Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1-3, a clamping mechanism is used in screw production, including base 1, holding tank 2 has been seted up at the top of base 1, holding tank 2's inside sliding connection has elevator 3, two transmission slots 4 that are the symmetric distribution have been seted up to base 1's inside, elevator 3's both sides are rotated and are connected with the transfer line 5 that is located transmission slot 4 inside, base 1's top sliding connection has two movable blocks 6 that are the symmetric distribution, movable block 6's bottom and transfer line 5 rotate to be connected, movable block 6's surface threaded connection has screw rod 7, screw rod 7's one end is rotated and is connected with grip block 16, specifically, grip block 16's surface is unevenness's stripe, improve the frictional force to the screw.

The scheme has the following working processes:

the large-size screw is placed on the base 1, then the lifting block 3 is pressed into the accommodating groove 2 by the weight of the screw, the lifting block 3 descends to drive one end of the transmission rod 5 to descend, the moving block 6 at the other end of the transmission rod 5 moves towards the middle of the base 1, then the screw is clamped through the clamping block 16, then the screw is processed, the screw is lifted after the processing is completed, a new screw is replaced for continuous processing, and when the screws with different sizes need to be processed, the distance between the clamping block 16 and the moving block 6 is adjusted through rotating the screw rod 7.

According to the working process, the following steps are known:

the two clamping blocks 16 are used for clamping screws through the weight of the screws with larger sizes, and the clamping blocks 16 can be adjusted through the screw rods 7, so that the clamping blocks 16 can clamp screws with different sizes, and the screws with different sizes can be conveniently clamped.

Further, the surface of the base 1 is provided with a sliding groove 8, the bottom of the moving block 6 is located inside the sliding groove 8, and specifically, the moving block 6 slides on the surface of the base 1 through the sliding groove 8.

Further, the top fixedly connected with support 9 of base 1, the surface of support 9 has extrusion piece 11 through first spring 10 elastic connection, and is concrete, gets into the extrusion through extrusion piece 11 to the screw of putting into base 1 top for the screw can not leave base 1 easily and make the unable centre gripping screw of grip block 16.

Further, constant head tank 12 has been seted up on the surface of screw rod 7, and the inside sliding connection of constant head tank 12 has dead lever 13, and a plurality of is the fixed slot 14 that the circumference distributes, and is concrete, makes screw rod 7 fixed after adjusting through dead lever 13 and fixed slot 14, prevents that screw rod 7 from rotating to make the centre gripping unstable.

Further, the cross-section of the positioning groove 12 is convex, and the cross-section of the fixing rod 13 is T-shaped, specifically, the fixing rod 13 is prevented from leaving the positioning groove 12, so that the screw 7 cannot be fixed.
