Description
Technical field
The present invention relates to a kind of fixture, particularly relate to a kind of clamping device of plate-type flange dish.
Background technology
Flange is interconnective part between pipe and pipe, for the connection between pipe end; Existing a kind of plate-type flange dish is circular plate, normally carries out welding with pipe end using, and then fixes two ring flanges with bolt, to complete welding between pipe with pipe; Now for the plate-type flange dish of larger shape, owing to being all unfavorable for clamping with chuck or other conventional clamp, what therefore adopt is that bolt is screwed on pedestal, all bolt has been evenly arranged at the endoporus of plate-type flange dish and periphery, carry out spacing with bolt to ring flange, then screw bolt, make the upper surface of bolt head supported flange dish; Although the method fixing-stable, complex operation, and each fixture only can clamp the ring flange of same size; In addition because ring flange itself has error, but this fixture can not adjust according to error, so make the centralized positioning effect of this fixture to ring flange bad.
Summary of the invention
The invention is intended to the clamping device that a kind of plate-type flange dish is provided, to improve the centralized positioning effect to plate-type flange dish, improve the scope of application of this fixture simultaneously.
The clamping device of base case plate-type flange dish of the present invention, comprises pedestal and top pressure bolt; Also comprise compact heap; Described pedestal upper end is provided with a circular groove, and the center of circular groove has the drive screw that is fixed on pedestal; Described compact heap is threaded on drive screw, and compact heap is tapered, and the small end of compact heap down; The sidewall of described circular groove is evenly equipped with at least three screwed holes, described top pressure bolt is identical with the number of described screwed hole; The screw front end of described top pressure bolt is configured to coniform, and top pressure bolt is screwed in the screwed hole of described pedestal respectively, and the front end of top pressure screw rod is towards the center of pedestal.
In this base case, plate-type flange dish is placed in the circular groove of pedestal, before laying board-like ring flange, need first compact heap to be screwed off from drive screw, after placing plate-type flange dish, then compact heap is being installed, by rotating compact heap, compact heap being moved down, thus makes the conical surface of compact heap and the endoporus close contact of plate-type flange dish, centralized positioning can be carried out to plate-type flange dish, from the inner ring of plate-type flange dish, it be clamped simultaneously; More firm in order to clamp, also need to clamp from the outer ring of plate-type flange dish it, namely top pressure bolt is rotated, top is made to press the tip of bolt to move to the outer of plate-type flange dish, then the conical surface of top pressure bolt can form extruding to the outer of plate-type flange dish, thus plate-type flange dish is close on the datum level of pedestal, thus complete the clamping to plate-type flange dish.
Owing to adopting the conical surface of compact heap and the endoporus of plate-type flange dish to form taper fit in this programme, thus to plate-type flange dish, there is good centralized positioning effect; In addition because compact heap is conical, therefore a compact heap can be formed with the endoporus of the plate-type flange dish of different size and coordinate, and comparatively large for the adjustable range of the top pressure bolt of outside clamping, so this fixture can be used for the plate-type flange dish clamping different size; But the size range of the plate-type flange dish that same compact heap can clamp is also limited, so the compact heap of different size can be arranged, to increase the scope of application of this fixture.
This programme utilizes the compact heap of taper, not only increases centralized positioning precision when holing to plate-type flange dish, and what also add this fixture can the scope of application simultaneously.
Preferred version one, as the further optimization to base case, described compact heap is provided with turning handle, and turning handle is threaded with described compact heap; Turning handle is conducive to rotating compact heap, and turning handle is threaded with compact heap, when holing to plate-type flange dish, can be taken off by turning handle, thus prevents turning handle from forming interference to drill bit.
Preferred version two, as the further optimization to base case, described pedestal is also provided with cannelure; Cannelure is not only drill bit and leaves space, also has the effect of deposition iron filings simultaneously, prevents iron filings by plate-type flange dish jack-up, and cannot fit with datum plane.
Preferred version three, as the further optimization to base case, described top pressure bolt is provided with eight, and the screwed hole on described pedestal is also provided with eight; The quantity increasing top pressure bolt can make clamping effect better, but top pressure bolt is too many, and the operation right side is too loaded down with trivial details.
Preferred version four, as the further optimization to base case, the sidewall of described circular groove has also been offered several breach; To the iron filings that the boring of plate-type flange dish produces, mostly all can be accumulated in circular groove, the sidewall of circular groove has offered breach, facilitate the cleaning of iron filings.

Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description comprises: pedestal 1, compact heap 2, top pressure bolt 3, plate-type flange dish 4, drive screw 11, breach 12, cannelure 13, turning handle 21.
Embodiment is substantially as shown in accompanying drawing 1, Fig. 2: the clamping device of plate-type flange dish comprises pedestal 1, compact heap 2 and top pressure bolt 3; Wherein pedestal 1 upper end is provided with a circular groove, and the center of circular groove has a drive screw 11, and the lower end of drive screw 11 is welded on support; And compact heap 2 is threaded on drive screw 11, compact heap 2 is tapered, and the small end of compact heap 2 down; The sidewall of the circular groove of pedestal 1 is provided with eight equally distributed screwed holes, top pressure bolt 3 has eight equally, the screw front end of top pressure bolt 3 is configured to coniform, for the tip of top pressure bolt 3, top pressure bolt 3 is screwed in the screwed hole of support respectively, and the tip of top pressure bolt 3 is towards the center of pedestal 1.
As shown in Figure 2, plate-type flange dish 4 is placed in the circular groove of pedestal 1, before laying board-like ring flange 4, need first compact heap 2 to be screwed off from drive screw 11, then installing compact heap 2, by rotating compact heap 2, compact heap 2 is moved down, thus make the conical surface of compact heap 2 and the endoporus close contact of plate-type flange dish 4, centralized positioning can be carried out to plate-type flange dish 4, from the inner ring of plate-type flange dish 4, it be clamped simultaneously; More firm in order to clamp, also need to clamp from the outer ring of plate-type flange dish 4 it, namely top pressure bolt 3 is rotated, top is made to press the tip of bolt 3 to move to the outer of plate-type flange dish 4, then the conical surface of top pressure bolt 3 can form extruding to the outer of plate-type flange dish 4 thus plate-type flange dish 4 is close on the datum level of pedestal 1, thus completes the clamping to plate-type flange dish 4.
As shown in Figure 2, for the ease of rotating compact heap 2, compact heap 2 is provided with turning handle 21, and turning handle 21 is threaded with compact heap 2, when holing to plate-type flange dish 4, turning handle 21 can be taken off, thus prevent turning handle 21 pairs of drill bits from forming interference.Get into pedestal 1 when holing to plate-type flange dish 4 to prevent drill bit, so pedestal 1 corresponds to drill bit place be also provided with cannelure 13, cannelure 13 is not only drill bit and leaves space, also has the effect of deposition iron filings simultaneously.As shown in the figure, to the iron filings that plate-type flange dish 4 boring produces, mostly all can be accumulated in circular groove, for the ease of clearing up iron filings, the sidewall of circular groove has also been offered several breach 12, and in circular groove, the iron filings of accumulation directly can scan out from breach 12.
