[0004] To achieve the above objectives, this utility model proposes a machining fixture for automotive control arms.

[0005] The technical solution of this utility model is implemented as follows: A machining fixture for an automotive control arm includes a base, a bracket connected to the top of the base, a sleeve fixedly connected to the top of the bracket, an insertion hole on the outside of the bracket, a movable disk slidably connected to the outside of the bracket, a fixed frame fixedly connected to the top of the movable disk, an adjustment component on the movable disk, the adjustment component including a support frame, a movable block, a placement plate and a drive mechanism, a support frame fixedly connected to the outside of the movable disk, a movable block slidably connected inside the support frame, a placement plate fixedly connected to the top of the movable block, a drive mechanism on the movable disk, a placement frame fixedly connected to the top of the support frame, a pressing mechanism on the placement plate and the placement frame, a fixing mechanism on the support frame, a pin movably connected inside the movable disk, and a control arm movably mounted on the placement plate and the placement frame.

[0006] Preferably, the driving mechanism includes a handle, a first rotating rod, a first gear, a ring gear, a second gear, a second rotating rod, and a rack. The first rotating rod is rotatably connected inside the fixed frame, a handle is fixedly connected to the top of the first rotating rod, a first gear is fixedly connected to the outside of the first rotating rod, a ring gear is rotatably connected to the inside of the fixed frame, a second rotating rod is rotatably connected inside the moving disk, a second gear is fixedly connected to the outside of the second rotating rod, and a rack is fixedly connected to the bottom of the moving block.

[0007] Preferably, the bottom of the ring gear is provided with a ring slider with a "T" shaped cross-section, which is slidably connected to the moving disk.

[0008] Preferably, the ring gear is meshed with the first gear and the second gear, and the second gear is meshed with the rack.

[0009] Preferably, the extrusion mechanism includes a first groove, a second groove, a push block, a moving rod, a clamping plate, and a first spring. The first groove is provided on the top of the placement plate, and the second groove is provided on the top of the placement frame. The moving rod is slidably connected inside the placement plate and the placement frame. The push block is fixedly connected to the top of the moving rod, and the clamping plate is fixedly connected to one side of the moving rod. The first spring is provided inside the placement plate and the placement frame.

[0010] Preferably, the clamping plate is located inside the first groove on the placement plate and the second groove on the placement frame, and one end of the moving rod is fixedly connected to the first spring.

[0011] Preferably, the fixing mechanism includes a lead screw, a second spring, a pressure plate, a round rod, and a rotating block.

[0012] Preferably, one end of the second spring is fixedly connected to the support frame, and the other end of the second spring is fixedly connected to the pressure plate.

[0013] This utility model has the following beneficial effects:

[0014] 1. This automotive control arm machining fixture uses a handle to rotate a first rotating rod, which in turn rotates a first gear. The first gear then rotates a ring gear, which in turn rotates a second gear and a second rotating rod. The second gear then moves a rack, which in turn moves a moving block on a support frame. The moving block then moves a placement plate closer to the support frame, thus allowing adjustment of the distance between the placement plate and the support frame. This allows the fixture to accommodate control arms of different sizes, thereby improving its practicality.

[0015] 2. This automotive control arm machining fixture, by rotating the rotating block on the lead screw, moves the rotating block downwards on the lead screw, which in turn pushes the pressure plate downwards. The pressure plate then drives the round rod to slide within the support frame. The round rod ensures the stability of the pressure plate during movement. At the same time, the pressure plate also compresses the second spring. As the pressure plate moves, it moves with the control arm. When the rotating block can no longer rotate, the pressure plate fixes the control arm to the placement plate and the placement frame. This prevents the control arms from colliding with each other during movement and ensures the surface quality of the product. Attached Figure Description

The second gear 708 is meshed with the rack 710.

[0029] By adopting the above technical solution, the distance between the placement plate 703 and the placement rack 8 can be adjusted by the drive mechanism.

[0030] Furthermore, the bottom of the ring gear 707 is provided with a ring slider with a "T" shaped cross-section, which is slidably connected to the movable disk 5.

[0031] By adopting the above technical solution and using a ring slider design with a T-shaped cross-section, the stability of the ring gear 707 during movement can be effectively ensured.

[0032] Furthermore, the extrusion mechanism includes a first groove 9, a second groove 10, a push block 11, a moving rod 12, a clamping plate 13, and a first spring 14.

One end of the moving rod 12 is fixedly connected to the first spring 14.

[0033] By adopting the above technical solution, the control arms 21 of different sizes can be initially fixed on the placement plate 703 and the placement rack 8 through the extrusion mechanism.

[0034] Furthermore, the fixing mechanism includes a lead screw 15, a second spring 16, a pressure plate 17, a round rod 18, and a rotating block 19. The lead screw 15 is fixedly connected to the top of the support frame 701, and the second spring 16 is sleeved on the outside of the lead screw 15. The round rod 18 is slidably connected inside the support frame 701, and the pressure plate 17 is fixedly connected to the top of the round rod 18.

One end of the second spring 16 is fixedly connected to the support frame 701, and the other end of the second spring 16 is fixedly connected to the pressure plate 17.

[0035] By adopting the above technical solution, control arms 21 of different sizes can be fixed on the placement plate 703 and the placement rack 8 through the fixing mechanism.

[0036] Working principle: In use, first move the movable disk 5 to the appropriate position, then insert the pin 20 into the socket 4 on the bracket 2 to fix the movable disk 5 on the bracket 2. Then, turn the handle 704. The handle 704 drives the first gear 706 to rotate through the first rotating rod 705. The first gear 706 drives the ring gear 707 to rotate. The ring gear 707 drives the second gear 708 and the second rotating rod 709 to rotate. The second gear 708 drives the rack 710 to move. The rack 710 drives the movable disk 5 to move. The movable block 702 moves on the support frame 701, causing the placement plate 703 to move closer to the placement frame 8. Once the placement plate 703 reaches the appropriate position, the handle 704 stops rotating. Then, the push block 11 on the placement plate 703 is pushed, causing the moving rod 12 to compress the first spring 14. Simultaneously, the moving rod 12 causes the clamping plate 13 to move within the first groove 9 on the placement plate 703. Afterward, one end of the control arm 21 is placed into the first groove 9 on the placement plate 703, and then the push block 11 is released. A spring 14 resets the clamping plate 13, which then clamps the placement plate 703. Next, pushing the push block 11 on the placement frame 8 allows the other end of the control arm 21 to be placed into the second groove 10 on the placement frame 8, and the clamping plate 13, in conjunction with the placement frame 8, clamps the other end of the control arm 21. The control arm 21 is then suspended on the placement plate 703 and the placement frame 8. After that, rotating the rotating block 19 on the lead screw 15 causes the rotating block 19 to move downwards on the lead screw 15, pushing the pressure plate 17 towards... As the pressure plate 17 moves downward, it drives the round rod 18 to slide within the support frame 701. The round rod 18 ensures the stability of the pressure plate 17 during movement. At the same time, the pressure plate 17 also compresses the second spring 16. As the pressure plate 17 moves, it connects with the control arm 21. When the rotating block 19 can no longer rotate, the pressure plate 17 fixes the control arm 21 to the placement plate 703 and the placement frame 8. In this way, the control arm 21 can be processed in the deep well heat treatment furnace through the sleeve 3. This avoids collisions between the control arms 21 during movement, ensuring the surface quality of the product.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
