The specific embodiment
The present invention is further illustrated below in conjunction with drawings and Examples.
Shown in Fig. 1～5.
A kind of gear shapping machine that has slide board type knife rack, comprise lathe bed 1, radially slide plate 2, column 3, transmission case 4, sliding carriage 5, knife rest 6, workbench 7, as shown in Figure 1, lathe bed 1 is provided with radial guidance 11 and workbench 7, radially slide plate 2 is installed on the radial guidance 11, and column 3 is installed in radially on the slide plate 2, and sliding carriage 5 is installed on the column 3, the top of sliding carriage 5 is equipped with transmission case 4, and the upper end of knife rest 6 is installed in the sliding carriage 5 and with transmission case 4 and links to each other; The both sides of sliding carriage 5 respectively be provided with one with column 3 on the guide rail 502,503 that matches of axial channel, the rear portion of sliding carriage 5 be provided with drive that it moves up and down, with column in the thread bush 501 that matches of the ball-screw installed; With respect to 502,503 liang of side positions of the guide rail on the sliding carriage 5 one cover counter weight device 8 is being installed respectively on the column 3; Knife rest 6 is positioned in the sliding carriage 5 by the support holes 504,505 of corresponding mounting groove both sides and the panel 506,507 of mounting groove two downsides in the sliding carriage 5.
In order to improve the integral rigidity of sliding carriage 5, on structural design, adopt double wall tubulose structure (as shown in Figure 2), reduce the weight of sliding carriage 5 on the one hand as far as possible, utilize computer to carry out force analysis on the other hand and reduce distortion.The swivel nut 501 of sliding carriage 5 by its rear portion is bearing on the ball screw and moves up and down, and is distributed in the guide rail 502 of both sides and the precision that guide rail 503 guarantees motion.The knife rest parts of gear shapping machine are positioned among the sliding carriage 5, mainly by the support holes 504,504 of slide plate both sides and panel 506,507 location of downside.
Because the direction of motion of sliding carriage 5 is vertical grounds, need carry out mass balance, otherwise the load change amount that sliding carriage 5 moves up and down is very big, even can't normally moves.Can utilize three-dimensional software to find the accurate position (as shown in Figure 3) of center of gravity earlier for this reason, owing to structural reason can't directly be carried out the application of force on this position, adopted counter weight device 8 to carry out weight balancing, counter weight device 8 is made up of oil cylinder 801, pulley 802,804 and chain 803 for this reason, one end of chain 803 links to each other with sliding carriage 5, the other end passes pulley 802,804 backs and links to each other with the axis of the piston of oil cylinder 801, when specifically implementing, oil cylinder 801 can be fixedly mounted on the back of column 3, as shown in Figure 4.
After sliding carriage 5 arrives the precalculated position, also need carry out the locking of sliding carriage 5 and just can carry out Gear Shaping.When Machine Tool design, adopt two cover locking devices 9,10, one cover carries out the locking (oil cylinder 902) of slide plate panel 901, one cover carries out the locking (oil cylinder 102 and oil cylinder 103) of the pressing plate 101 and the pressing plate 104 of operating slide guideway rail, as shown in Figure 5, two cover sliding carriage locking devices 9 are installed in column 3,10, wherein locking device 9 is formed by being adjacent to panel of installing on the another side in column 3, relative with corresponding datum level on the sliding carriage 5 901 and the locking cylinder 902 that is installed in the column 3, and the axis of the piston of locking cylinder 902 and panel 901 offset; Locking device 10 is by pressing plate 101,104, oil cylinder 102,103 form, the part of pressing plate 101,104 is fixed on the column 3, and another part contacts with locating surface on the sliding carriage 5, oil cylinder 102,103 are installed in respectively in the corresponding pressing plate 101,104, and its piston stretches out oil cylinder locating surface outer and on the sliding carriage 5 and contacts.
The part that the present invention does not relate to prior art that maybe can adopt same as the prior art is realized.
Adopt sliding carriage to realize the adjustment of stroke, carrying out weight balancing by oil cylinder, chain is core content of the present invention, and the gear shapping machine of all employing similar structures all is considered to equivalence of the present invention and replaces.
