Detailed Description

The essential features and advantages of the invention will be further explained below with reference to examples, but the invention is not limited to the embodiments listed.

As shown in fig. 1 to 6, the multi-gear positioning fixture of the present embodiment includes a base plate 1, a partition plate 2 and a clamping device 3, wherein the partition plate 2 and the clamping device 3 are arranged on the base plate 1 at intervals. The clamping device 3 comprises a driving rod 4, a moving block 5, a sliding block 6 and an elastic component 7, wherein the moving block 5 is provided with a through hole 51, and the driving rod 4 is arranged in the through hole 51 in a penetrating mode and is in threaded connection with the bottom plate 1. The sliding blocks 6 are disposed on both sides of the moving block 5, the sliding blocks 6 and the moving block 5 are connected by a contact surface 8, and the contact surface 8 is disposed obliquely and has a plurality of bent portions 81. Elastic component 7 sets up in sliding block 6 both sides, and elastic component 7 connects two sliding blocks 6, sliding block 6 one side has the face of supporting 61. In the technical scheme, the gear 10 is placed on the bottom plate 1 and positioned between the partition plate 2 and the clamping device 3, and the gears 10 on two sides are clamped through the clamping device 3. By providing a plurality of spacers 2 and clamps 3, a plurality of gears 10 can be fixed to the base plate 1. Through the up-and-down movement of the driving rod 4 and the contact surface 8 which is obliquely arranged, the moving block 5 can drive the sliding block 6 to move horizontally, so that the sliding block compresses the two side gears 10. By providing the bent portion 81, the distance between the sliding block 6 and the moving block 5 can be restricted. By arranging the elastic component 7, when the driving rod 4 goes upwards, the two sliding blocks 6 can be closed by elastic force, and the gear 10 is released. Through the technical scheme, the clamping device 3 can simultaneously position the gears on two sides, so that the gears are synchronously machined, and the machining efficiency is high; in addition, can increase or reduce clamping device according to gear quantity, the dismouting of being convenient for between bottom plate and the clamping device, it is more nimble convenient to use. In this embodiment, the driving rod is a screw.

In this embodiment, the contact surface 8 is M-shaped, so that the contact area can be increased without causing relative left-right movement between the moving block 5 and the sliding block 6.
