Description

Technical Field

[0001] This utility model relates to the field of clamping technology, and in particular to a pin alignment clamping fixture. Background Technology

[0002] In existing mechanical engineering processing, when the pin plate is welded to the pin, it will cause a large deformation, and the perpendicularity between the pin and the pin plate is difficult to guarantee. At this time, it is necessary to correct the welded pin plate. The most common method is to hold the pin and tap the pin plate with a rubber hammer to correct it. This method is not only laborious, but also unsafe. Utility Model Content

[0003] The purpose of this invention is to provide a pin alignment clamping fixture to replace hand-held clamping, which can safely and effortlessly align the pin plate.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A pin-shaft alignment clamping fixture includes two side plates vertically mounted on a worktable and a rear plate fixedly connected to the rear side of the two side plates; a fixed V-block is provided on the inner side of the rear plate, and the V-groove on it is located on the side away from the rear plate; a plurality of threaded holes are evenly distributed along the longitudinal direction on the front side of the side plate for connecting the fixed plate with bolts; the two side plates are symmetrically arranged, and a plurality of sliding grooves are provided along the longitudinal direction on the inner side of each plate for slidingly connecting the movable V-block, the V-groove on the movable V-block cooperating with the V-groove on the fixed V-block to clamp and align the workpiece; a screw is screwed to the middle of the fixed plate, one end of the screw is provided with a handle, and the other end is connected to the movable V-block for pushing the movable V-block to slide.

[0006] Preferably, the movable V-block is provided with two U-shaped connecting blocks on the side near the screw, and a connecting sleeve is provided on the screw. The connecting sleeve has a circumferential groove so that it can be rotatably connected to the U-shaped connecting block without disengaging.

[0007] Preferably, the screw has a large-pitch thread, which facilitates quick rotation of the screw to press the movable V-block.

[0008] Compared with the prior art, the advantages of this utility model are as follows: the utility model has a reasonable design structure and is easy to operate. It can quickly clamp and correct the deformed pin plate after welding, and can be used to correct pin plates of different lengths, thereby improving production efficiency and production safety.

[0012] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0013] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0014] like Figures 1 to 2 As shown, this embodiment of the utility model includes two side plates 2 vertically arranged on the workbench 1 and a rear plate 3 fixedly connected to the rear side of the two side plates 2; a fixed V-block 9 is provided on the inner side of the rear plate 3, and the V-groove on it is located on the side away from the rear plate 3; a number of threaded holes 201 are evenly distributed along the longitudinal direction on the front side of the side plate 2 for connecting the fixed plate 4 with bolts; the two side plates 2 are symmetrically arranged, and a number of sliding grooves 202 are provided along the longitudinal direction on the inner side of each side for slidingly connecting the movable V-block 8, and the V-groove on the movable V-block 8 cooperates with the V-groove on the fixed V-block 9 to clamp and correct the workpiece 10; a screw rod 5 is screwed to the middle of the fixed plate 4, one end of the screw rod 5 is provided with a handle 6, and the other end is connected to the movable V-block 8 for pushing the movable V-block 8 to slide.

[0015] like Figure 2 As shown, the movable V-shaped block 8 is provided with two U-shaped connecting blocks 7 on the side near the screw 5. The screw 5 is provided with a connecting sleeve 11, which has a circumferential groove so that it can be rotatably connected to the U-shaped connecting block 7 without detaching.
