Description

Technical Field

[0001] The utility model is applicable to the technical field of automobile parts processing, and particularly relates to an automobile parts clamping device. Background Art

[0002] At present, in the process of automobile assembly, in order to ensure the transportation of multiple liquids, hollow pipes are often needed for connected transportation. When producing hollow pipe accessories, the hollow pipes are clamped and fixed, and their outer wall surfaces are polished and deburred.

[0003] However, when clamping hollow pipes today, the clamping mechanism often clamps and secures them from the outside of the pipe. This clamping method easily blocks the pipe's outer wall, affecting the efficiency of subsequent surface deburring. Furthermore, the required clamping and securing operations are cumbersome, affecting the efficiency of the pipe clamping and securing process. Therefore, we propose a clamping device for automotive parts. Utility Model Content

[0008] A first connecting frame is movably sleeved on the middle portion of the outer side of the transmission gear, and a second connecting frame is movably sleeved on the outer side of the transmission gear. A follower rack is fixedly mounted on the top inner side of the first connecting frame and the bottom inner side of the second connecting frame, and the outer side of the follower rack is meshed with the outer side of the transmission rack.

[0009] Connecting rods are fixedly installed on both end surfaces of the outer side of the transmission plate, a lifting plate is slidably sleeved on the outer bottom of the fixed tube, and the inner side of the lifting plate is fixedly connected to the outer side of the connecting rod.

[0010] By adopting the above technical solution, through the meshing of the transmission gear and the transmission rack, and under the meshing transmission action of the follower rack and the transmission rack, the operator can put the pipe to be clamped and processed on the outside of the fixed pipe and continue to push it downward, thereby driving the fitting arc plate to move synchronously from the inside of the pipe to the outside and fit against the inner wall of the pipe to clamp it, while ensuring the stability of the pipe clamping and fixing, avoiding the clamping obstruction of the outer wall of the pipe and affecting the normal progress of subsequent processing.

[0011] As an optional solution of the technical solution of the present application, a transmission frame is vertically fixedly installed on the outer top surface of the first connecting frame and the second connecting frame, and the side of the transmission frame is fixedly connected to the outer side of the fitting arc plate.

[0012] By adopting the above technical solution, the transmission rationality of the entire device is ensured through the transmission connection of the transmission frame.

[0013] As an optional solution of the technical solution of the present application, sliding grooves are provided at both ends of the bottom side of the fixed tube, and the connecting rod is slidably installed inside the sliding groove.

[0014] By adopting the above technical solution, the vertical movement stability of the lifting plate is ensured by the guiding sliding action of the sliding groove on the connecting rod.

[0015] As an optional solution to the technical solution of the present application, mounting plates are fixedly installed on both side surfaces of the bottom of the lifting plate, and the mounting plates are slidably installed on the outside of the bottom of the fixed tube. A tightening bolt is screwed through the middle end of each mounting plate, and the tightening bolt is located on the outside of the fixed tube.

[0016] By adopting the above technical solution, the clamping and fixing stability of the pipeline is ensured by the tightening and limiting action of the tightening bolt.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The cam is engaged with the gear train of the driver and the control gear of the driver, and the cam is engaged with the gear train of the driver and the control gear of the driver, and the control gear of the driver and the control gear of the control gear are engaged with each other, so that the cam can be connected with the gear train of the driver and the control gear of the control gear of the control gear.

[0019] 2. The technical solution of the present application is an automobile parts clamping device, which is equipped with tightening bolts on both sides of the bottom of the lifting plate. Combined with the tightening and pushing action of the tightening bolts, the vertical movement of the lifting plate can be limited to prevent the lifting plate from moving arbitrarily and affecting the fitting stability of the arc plate against the inner wall of the hollow pipe.
