Detailed Description
The present invention will be further described with reference to the accompanying drawings and embodiments.
Referring to fig. 1-5, in an embodiment of the present invention, a clamp for machining a numerically controlled lathe includes: a platform 1; the device comprises a first supporting plate 2 and a second supporting plate 3, wherein the first supporting plate 2 and the second supporting plate 3 are both fixedly arranged at the top of a platform 1; fixing mechanism, fixing mechanism locates the top of platform 1, fixing mechanism includes dwang 4, dwang 4 runs through first backup pad 2 and with first backup pad 2 rotates to be connected, the one end fixed mounting of dwang 4 has first installation piece 5, one side fixed mounting of first installation piece 5 has four springs 6, one side of first installation piece 5 is equipped with first splint 7, four the equal fixed mounting of one end that first installation piece 5 was kept away from to spring 6 is on first splint 7, one side fixed mounting of second backup pad 3 has pneumatic cylinder 8, rotate on pneumatic cylinder 8's the output shaft and install second splint 9.
The top fixed mounting of platform 1 has bracing piece 14, the top fixed mounting of bracing piece 14 sets up bracing piece 14 on pneumatic cylinder 8 for pneumatic cylinder 8 is more stable.
The last fixed mounting of pneumatic cylinder 8 has second installation piece 15, second screw hole 16 has been seted up on the second installation piece 15, the top of pneumatic cylinder 8 is equipped with second screw 17, second screw 17 runs through second screw hole 16 and with second screw hole 16 threaded connection, the fixed cover is equipped with third installation piece 18 on the output shaft of pneumatic cylinder 8.
