Description

Technical Field

[0001] This utility model belongs to the technical field of automotive parts processing equipment, and in particular relates to a positioning device for automotive parts processing. Background Technology

[0002] When processing automotive parts, fixtures are required to fix the position. Fixtures are process equipment used in machining, assembly and other production processes to accurately position and clamp the workpiece through components or combinations of components such as locating pins, locating blocks, and V-blocks, so as to ensure the accuracy of machining or assembly. Types of fixtures include special fixtures and combination fixtures.

[0003] Because automotive parts vary greatly in height, and most clamping fixtures that can clamp quickly have a very short travel, the fit between the fixtures and the automotive parts is relatively poor.

[0004] To address this issue, we propose a positioning device for automotive parts processing. Utility Model Content

[0005] The purpose of this invention is to solve the problem of low matching degree between fixtures and automotive parts, and to propose a positioning device for automotive parts processing.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A positioning device for processing automotive parts includes a hydraulic cylinder. A pressure claw is rotatably mounted on the piston rod of the hydraulic cylinder. A first connecting rod is rotatably connected to the side of the pressure claw, and a second connecting rod is rotatably connected to the lower part of the first connecting rod. A lifting frame is provided outside the hydraulic cylinder and the second connecting rod. The lower ends of the hydraulic cylinder and the second connecting rod are fixedly connected to the lower part of the lifting frame. A spring clip is provided inside the lifting frame, and the upper end of the spring clip is fixedly connected to the upper part of the lifting frame. A guide frame is slidably mounted inside the lifting frame, and the spring clip engages with the guide frame. Pushing the spring clip inward disengages it from the guide frame, and then pulling it upward causes the lifting frame to rise through the action of the spring clip. This, in turn, raises the hydraulic cylinder and the second connecting rod, increasing their base height. Conversely, the reverse operation lowers their base height, facilitating adjustment of the extrusion clamping height and improving compatibility with different automotive parts thicknesses.

[0008] Preferably, the guide frame includes a fixed plate, and a guide post is fixedly connected to the upper part of the fixed plate. The guide post has a locking groove at its corner. The guide post facilitates the lifting and lowering of the lifting frame, and the locking groove facilitates the fastening and fixing of the spring clips.

[0009] Preferably, the lifting frame includes a mounting plate, with the lower ends of the hydraulic cylinder and the second connecting rod fixedly connected to the upper end of the mounting plate. A portal frame is fixedly connected to the side of the mounting plate, and the portal frame is slidably mounted on a guide post. The mounting plate is in movable contact with the fixed plate. The guide post guides the portal frame to slide and rise, and the mounting plate acts on the hydraulic cylinder and the second connecting rod, facilitating the lifting frame to rise or fall.

[0010] Preferably, the lifting frame further includes a stop bar that slides against the side of the guide column. Using the stop bar against the side of the guide column increases the stability of the lifting frame's sliding position.

[0011] Preferably, the spring clip includes a spring piece, the upper end of which is fixedly connected to the door-shaped frame, and the lower part of which is fixedly connected to a latch block and a button. The latch block is fastened in a latch groove. Pressing the button inward causes the lower part of the spring piece to disengage the latch block from the latch groove, thereby disengaging the spring clip from the guide frame. Simultaneously, using both hands to open the spring clips on both sides, then adjusting the lifting frame higher or lower, and releasing the button allows the spring piece to use its own elasticity to act on the latch block, causing the latch block to re-fasten into the latch groove, facilitating control of the lifting frame's fixation or raising / lowering.

[0012] Preferably, the spring clip further includes a pressing plate, which is fixedly connected to the end of the button facing away from the spring piece. The pressing plate increases the force range of the spring clip and the hand, reducing the pressure exerted by the spring clip on the hand.

[0013] In summary, the technical effects and advantages of this utility model are as follows:

[0014] 1. Push the spring clip inward to disengage it from the guide frame, then pull it upward. The spring clip acts on the lifting frame, causing it to rise. The lifting frame then raises the hydraulic cylinder and the second connecting rod, increasing their base height. Similarly, reverse the operation to lower the base height of the hydraulic cylinder and the second connecting rod. This facilitates adjustment of the extrusion clamping height and improves the compatibility with the thickness of different automotive parts.

[0015] 2. The guide column guides the sliding and lifting of the portal frame, and the mounting plate acts on the hydraulic cylinder and the second connecting rod to facilitate the lifting frame to rise or fall.

[0016] 3. Press the button inward to act on the lower part of the spring piece, causing the buckle to disengage from the buckle groove, thereby releasing the spring buckle from the guide frame. At the same time, use both hands to open the spring buckles on both sides, then adjust the lifting frame up or down, release the button, and let the spring piece use its own elasticity to act on the buckle, causing the buckle to re-engage into the buckle groove, making it easy to control the fixing or raising and lowering of the lifting frame.

[0022] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0023] like Figure 1 As shown, a positioning device for processing automotive parts includes a hydraulic cylinder 1. A pressure claw 6 is rotatably mounted on the piston rod of the hydraulic cylinder 1. A first connecting rod 7 is rotatably connected to the side of the pressure claw 6, and a second connecting rod 5 is rotatably connected to the lower part of the first connecting rod 7. A lifting frame 3 is provided outside the hydraulic cylinder 1 and the second connecting rod 5. The lower ends of the hydraulic cylinder 1 and the second connecting rod 5 are fixedly connected to the lower part of the lifting frame 3. A spring clip 4 is provided inside the lifting frame 3, and the upper end of the spring clip 4 is fixedly connected to the upper part of the lifting frame 3. A guide frame 2 is slidably mounted inside the lifting frame 3, and the spring clip 4 is engaged with the guide frame 2. Driving the hydraulic cylinder 1 to retract pulls the tail of the pressure claw 6, causing the front of the pressure claw 6 to lift. Driving the hydraulic cylinder 1 to retract pulls the tail of the pressure claw 6, causing the head of the pressure claw 6 to press against the target automotive part.

[0024] like Figure 1 and 2 As shown, the guide frame 2 includes a fixed plate 21, and a guide post 22 is fixedly connected to the upper part of the fixed plate 21. The guide post 22 has a buckle groove 23 at its corner. The guide post 22 guides the lifting frame 3 to rise and fall, and the buckle groove 23 is used to engage the spring buckle 4.

[0025] like Figure 1 and 3 As shown, the lifting frame 3 includes a mounting plate 31. The lower ends of the hydraulic cylinder 1 and the second connecting rod 5 are fixedly connected to the upper end of the mounting plate 31. A portal frame 32 is fixedly connected to the side of the mounting plate 31. The portal frame 32 is slidably mounted on the guide post 22. The mounting plate 31 is in movable contact with the fixed plate 21. The guide post 22 guides the portal frame 32 to slide and rise, and the mounting plate 31 acts on the hydraulic cylinder 1 and the second connecting rod 5.

[0026] like Figure 1 and 3 As shown, the lifting frame 3 also includes a stop bar 33, which slides against the side of the guide post 22. The stop bar 33, positioned against the side of the guide post 22, increases the stability of the sliding position of the lifting frame 3.

[0027] like Figure 1 , 2 As shown in Figure 4, the spring clip 4 includes a spring piece 41. The upper end of the spring piece 41 is fixedly connected to the door frame 32, and the lower part of the spring piece 41 is fixedly connected to a buckle block 44 and a button 42. The buckle block 44 is fastened in the buckle groove 23. Pressing the button 42 inward causes the button 42 to act on the lower part of the spring piece 41, causing the buckle block 44 to disengage from the buckle groove 23, thereby disengaging the spring clip 4 from the guide frame 2. At the same time, use both hands to open the spring clips 4 on both sides, then adjust the lifting frame 3 up or down, release the button 42, and let the spring piece 41 use its own elasticity to act on the buckle block 44, causing the buckle block 44 to re-fasten into the buckle groove 23.

[0028] like Figure 1 and 4 As shown, the spring clip 4 also includes a pressing plate 43, which is fixedly connected to the end of the button 42 facing away from the spring piece 41. The pressing plate 43 increases the force range of the spring clip 4 and the hand, reducing the pressure of the spring clip 4 on the hand.

[0029] Working principle: Push the spring clip 4 inward to disengage it from the guide frame 2, then pull it upward. The spring clip 4 acts on the lifting frame 3, causing the lifting frame 3 to rise. The lifting frame 3 then drives the hydraulic cylinder 1 and the second connecting rod 5 to rise, increasing the base height of the hydraulic cylinder 1 and the second connecting rod 5. Similarly, the reverse operation lowers the base height of the hydraulic cylinder 1 and the second connecting rod 5, making it easier to adjust the extrusion clamping height.

[0030] The above description is only a preferred embodiment of the utility model, but the protection scope of the utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed by the utility model, based on the technical solution and the utility model concept, should be included within the protection scope of the utility model.

[0031] The description briefly mentions the application direction of the utility model in relation to existing technologies known to those skilled in the art without modification, and combines them with the utility model to form a complete technology; it avoids excessive popularization of technologies known to those skilled in the art, in order to help those skilled in the art quickly understand the main content of the utility model.
