Description

A kind of sleeping mill clamping device

Technical field

The utility model belongs to field of machining, is related to a kind of Quick-clamped tooling applied to sleeping Milling Machining.

Background technique

Sleeping milling is common processing method, and various shapes, the Workpiece clamping such as processable plane, groove mostly use vice, But for rod piece or shaft member, this clamping mode is line contact, above and below the frictional force prevention workpiece for clamping generation Displacement, so using parallels mostly below workpiece.For easily-consumed products this for the drill steel of quartering hammer, the structure of drill steel such as attached drawing Shown in 1, the cotter pilotage slot of drill steel can on horizontal milling machine rapid processing, but since the cotter pilotage slot of drill steel two sides has position of related features to want It asks, after the cotter pilotage slot processing of side, the positioning of drill steel, clamping are two devices respectively, also need to verify its verticality after clamping Or the depth of parallelism needs to unclamp repositioning clamping if it does not meet the requirements, causes the processing efficiency of second cotter pilotage slot extremely low, It is serious to restrict rhythm of production, cause working hour to increase, increased costs.

Summary of the invention

The technical issues of the utility model is solved is: providing a kind of sleeping Milling Machining fast fixture of drill steel, improves pricker The processing efficiency of bar cotter pilotage slot.

The technical scheme adopted by the utility model is

This sleeping mill clamping device is fixed on milling machine table table top by fastener, including two L-type locating pieces and pressure Tight mechanism；The hold-down mechanism includes L-type pedestal, axis, pressing plate, hold-down bolt, lead screw locating piece, lead screw and adjustable slide；Institute The centre for stating adjustable slide is machined with T-slot through front and back, is fixedly arranged at the front end with lead screw positioning in T-slot oriented manipulation person Block；The L-type pedestal is installed on above adjustable slide, is machined in the lower part of L-type pedestal and is matched with adjustable slide T-slot T-type convex block is machined with and the matched tapped through hole I of lead screw on the convex block；Lead screw passes through the tapped through hole I, is positioned by lead screw Block positioning；There are two pieces of risers on the top of the L-type pedestal, consistent through-hole I is machined on riser, pressing plate is placed on two pieces and erects The centre of plate is connect by the axis being mounted in through-hole I with L-type pedestal；It is threaded in the non-aid section of the pressing plate logical Hole II, the tapped through hole II and hold-down bolt cooperate.

The beneficial effect that the utility model obtains is: the device can realize Quick-clamped and the positioning of drill steel, greatly improve Drill steel crouches Milling Machining efficiency, has saved the time that is loaded, ensure that machining accuracy.

Specific embodiment

The sleeping milling fast fixture of the utility model is as shown in Fig. 2, including two L-type locating pieces 2 and hold-down mechanism.Institute L-type locating piece 2 is stated to be fixedly connected using fasteners such as bolt I 4, bolt III 14 and nuts I 3 with workbench 1.L-type locating piece 2 Structure is as shown in Fig. 3, and a bolt garden through-hole is machined on boss 2-1, and the long garden of bolt is machined on platform 2-2 Through-hole, to adjust the position of fixing bolt.

The hold-down mechanism includes L-type pedestal 5, axis 6, pressing plate 7, hold-down bolt 8, lead screw locating piece 9, lead screw 10 and adjustable Slide 11.

The adjustable slide 11 is tetragonal body structure, and as shown in Fig. 4, both sides are machined with fluting stepped bolt through-hole 11-1 is fixedly connected with workbench 1 by fasteners such as nut II 12, bolts II 13, is machined with the T through front and back in the middle Type groove 11-2.It is fixedly arranged at the front end with lead screw locating piece 9 towards operator in T-slot 11-2, for fixing lead screw 10.Lead screw positioning The structure of block 9 and lead screw 10 is shown in attached Figures 5 and 6.

The L-type pedestal 5 is installed on above adjustable slide 11, and structure is as shown in attached drawing 7 and attached drawing 8.In L-type pedestal 5 Lower part be machined with the T-type convex block 5-1 to match with the T-slot 11-2 of adjustable slide, be machined with and lead screw 10 on convex block 5-1 Matched I 5-4 of tapped through hole.Lead screw 10 passes through I 5-4 of the tapped through hole, is positioned by lead screw locating piece 9, when lead screw 10 rotates, The back-and-forth motion of adjustable L-type pedestal 5.There are two pieces of riser 5-2 on the top of L-type pedestal 5, is machined on riser 5-2 consistent I 5-3 of through-hole, pressing plate 7 are placed on the centre of two pieces of riser 5-2, pass through the axis 6 and L-type pedestal 5 being mounted in two I 5-3 of through-hole Connection.The structure of the pressing plate 7 is as shown in Fig. 9, and aid section 7-1 is machined with II 7-2 of through-hole cooperated with axis 6, and the other end is Non- aid section 7-3, is threaded II 7-4 of through-hole, to cooperate with hold-down bolt 8.When tightening or unclamping hold-down bolt 8, pressure Plate 7 is rotated around axis 6, for compressing or unclamping drill steel.

In use, two L-type locating pieces 2 to be first fixed on to the suitable position of milling machine table 1, then according to drill steel model With drill steel cotter pilotage groove location, hold-down mechanism is fixed.Drill steel 15 is placed on two L-type locating pieces 2, rotating threaded shaft 10 uses L The seal face of type pedestal 5 compresses drill steel 15.Then bolt 8 is rotatably compressed, compression bar 7 is rotated around axis 6, realizes the pressure to drill steel 15 Tightly.After drill steel clamps, the cotter pilotage slot for Milling Machining drill steel side of crouching.

First cotter pilotage slot after processing is completed, unclamps hold-down bolt 8 and lead screw 10, rough 180 ° of drill steel or so of rotation will The seal face of the cotter pilotage slot alignment L-type pedestal 5 processed, as shown in Fig. 10, rotating threaded shaft 10, L-type pedestal 5 compresses cotter pilotage Slot utilizes the Planar realization of the seal face and cotter pilotage slot since the table top of the seal face and workbench 1 of L-type pedestal 5 is perpendicular The quick positioning and pre- clamping of drill steel 15, then rotatably compress bolt 8, and compression bar 7 is rotated around axis 6, is realized to drill steel 15 again It clamps.After clamping, the cotter pilotage slot of the other side of drill steel is processed.

This sleeping milling fast fixture can Quick-clamped drill steel, positioned using machined cotter pilotage slot, ensure that two it is flat The position of related features of cotter way.The utility model can realize groove or plane of the rod-shaped or shaft-like class workpiece with relative positional relationship Sleeping Milling Machining, is either mutually perpendicular to or parallel groove or plan-position require, if guarantee the seal face of L-type pedestal 5 with Workbench is vertical.The device can realize Quick-clamped and the positioning of workpiece, substantially increase that drill steel etc. is rod-shaped or shaft-like The sleeping Milling Machining efficiency of class workpiece, has saved the time that is loaded, ensure that machining accuracy.
