Description

Technical Field

[0001] This utility model relates to an adjustable control lever with multi-specification quick-change clamping mechanism. Background Technology

[0002] In automotive parts production lines, the processing, inspection, or assembly of control levers requires precise and stable clamping using fixtures to ensure processing accuracy and operational safety. Currently, such clamping mechanisms are extremely common in industrial applications, but existing technologies have significant shortcomings and urgently need improvement to adapt to the flexible production needs of diverse products and small batches.

[0003] Traditional clamping mechanisms typically employ a "one lever, one dedicated" design concept, meaning that a dedicated clamp must be customized for each length or specification of control lever (such as brake levers or gear shift levers for different car models). This design results in a severe lack of equipment versatility, requiring manufacturers to maintain a large inventory of dedicated clamps, which not only increases warehousing costs but also wastes resources. For example, when switching product specifications, operators need to disassemble the original clamp, install the new clamp, and perform tedious adjustments, a process that can take tens of minutes, significantly reducing the changeover efficiency and overall capacity of the production line. In view of this, this utility model proposes an adjustable control lever multi-specification quick-change clamping mechanism to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable control lever with multi-specification quick-change clamping mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An adjustable control lever multi-specification quick-change clamping mechanism includes a placement plate, wherein the placement plate is provided with an adjustment through groove;

[0007] The adjustment channel is provided with multiple sets of clamping claws, and the placement plate is provided with a lifting and lowering placement rod. The placement rod is provided with multiple sets of adjustment components, and the multiple sets of adjustment components are respectively connected to the multiple sets of clamping claws. The adjustment components are displaced and adjusted on the placement rod, so that the clamping claws are displaced and adjusted in the adjustment channel to adapt to different specifications of car control levers.

[0008] As an improvement to the above technical solution, the clamping claw is provided with a movable plate, which is slidably disposed in the adjustment slot;

[0009] The movable plate is provided with a movable block, and clamping rods are hinged to both ends of the movable block. Clamping blocks are provided on the clamping rods by bolts, and clamping plates are provided on the clamping blocks.

[0010] As an improvement to the above technical solution, a through moving hole is provided between the moving plate and the moving block, a moving rod is provided in the moving hole, a connecting plate is provided on the moving rod, and movable rods are hinged at both ends of the connecting plate. The two sets of movable rods are respectively hinged to two sets of clamping rods.

[0011] As an improvement to the above technical solution, guide grooves are provided on both sides of the adjustment channel, and guide plates are provided at both ends of the moving plate. The two sets of guide plates are slidably arranged in the two sets of guide grooves respectively.

[0012] As an improvement to the above technical solution, the adjustment component includes an adjustment block, the adjustment block having adjustment holes, and the placement rod being disposed in multiple sets of adjustment holes.

[0013] As an improvement to the above technical solution, the outer wall of the placement rod is provided with a threaded outer wall;

[0014] Adjusting nuts are provided on both sides of the adjusting block. The adjusting nuts are threaded into the outer wall of the threaded rod, so that the adjusting nuts are threaded onto the outer wall of the rod.

[0015] As an improvement to the above technical solution, the placement plate is provided with four sets of mounting rods, and the bottom end of the four sets of mounting rods is provided with a fixing plate;

[0016] The placement rod is provided with lifting plates at both ends, and the lifting plates are provided with lifting sleeves at both ends. The two sets of lifting sleeves are slidably mounted on the two sets of mounting rods on the same side.

[0017] As an improvement to the above technical solution, the fixing plate is provided with multiple sets of cylinder fixing holes, and the multiple sets of cylinder fixing holes are matched with the positions of the two sets of lifting plates.

[0018] A lifting cylinder is provided on the cylinder fixing hole to be connected to the lifting plate.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] By adjusting the axial displacement of the component along the placement rod, the linkage clamping claw slides synchronously in the adjustment slot, realizing stepless adjustment of the clamping distance. This structure allows a single clamping mechanism to be adapted to automotive control levers (such as brake levers and gear shift levers) of different lengths, breaking through the limitation of traditional clamps that are dedicated to one lever and significantly improving the versatility of the equipment.

[0021] The pre-adjustable quick positioning mechanism allows operators to set the gripper spacing simply by adjusting the components, eliminating the need to disassemble and replace the fixtures and effectively reducing changeover time.

[0022] The rigid pressing structure of the lifting placement rod ensures that multiple sets of clamping claws apply uniform and synchronous clamping force to the control rod, avoiding workpiece deflection or surface damage caused by asynchronous clamping. Attached Figure Description

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] Example:

[0032] like Figure 1-6 As shown, this embodiment proposes an adjustable control lever multi-specification quick-change clamping mechanism, including a placement plate 10, on which an adjustment through groove 13 is provided;

[0033] The adjustment slot 13 is provided with multiple sets of clamping claws 20, and the placement plate 10 is provided with a lifting and lowering placement rod 30. The placement rod 30 is provided with multiple sets of adjustment components 40. The multiple sets of adjustment components 40 are respectively connected to the multiple sets of clamping claws 20. The adjustment components 40 are displaced and adjusted on the placement rod 30, so that the clamping claws 20 are displaced and adjusted in the adjustment slot 13 to adapt to different specifications of car control levers.

[0034] In this embodiment, when clamping the car control lever, the adjustment component 40 is first adjusted to move along the axis of the placement rod 30 by adjusting the cooperation between the component 40 and the placement rod 30, thereby causing the clamping claw 20 to move in the adjustment slot 13 until the multiple clamping claws 20 are adjusted to fit the length of the car control lever to be clamped. Then, the car control lever is placed between the multiple clamping claws 20, and the placement rod 30 is pressed down so that the multiple clamping claws 20 clamp the car control lever at the same time, thereby completing the clamping process.

[0035] By adjusting the axial displacement of component 40 along the placement rod 30, the linkage clamping claw 20 slides synchronously in the adjustment slot 13, realizing stepless adjustment of the clamping distance. This structure allows a single clamping mechanism to be adapted to automotive control levers of different lengths, such as brake levers and gear shift levers, breaking through the limitation of traditional clamps that are dedicated to one lever and significantly improving the equipment's versatility.

[0036] The pre-adjustable quick positioning mechanism allows the operator to set the gripper spacing simply by adjusting component 40, eliminating the need to disassemble and replace the fixture and effectively reducing changeover time.

[0037] The rigid pressing structure of the lifting placement rod 30 enables multiple sets of clamping claws 20 to apply uniform and synchronous clamping force to the control rod, avoiding workpiece deflection or surface damage caused by asynchronous clamping.

[0038] Specifically, the clamping claw 20 is provided with a movable plate 21, which is slidably disposed in the adjustment slot 13;

[0039] The movable plate 21 is provided with a movable block 23, and the two ends of the movable block 23 are hinged with clamping rods 24. The clamping rods 24 are provided with clamping blocks 27 connected by bolts, and the clamping blocks 27 are provided with clamping plates 28.

[0040] In this embodiment, the movable plate 21 is slidably disposed in the adjustment slot 13, so that the clamping claw 20 can perform stepless linear displacement along a predetermined trajectory, thereby realizing rapid and precise adjustment of the clamping distance. This directly adapts to car control levers of different lengths, such as gear shift levers and brake levers, and the changeover time is shorter than that of traditional clamps.

[0041] Of course, when clamping the car control lever, a pre-clamping process can be performed first to make the clamping plate 28 contact the car control lever. When the clamping plate 28 on other clamping claws 20 cannot contact the car control lever, the clamping plate 28 can be replaced until the clamping claws 20 can successfully contact the car control lever to complete the clamping process. Of course, the thickness, shape, material, etc. of the clamping plate 28 can be adapted according to the function of the clamping area. The clamping block 27 is connected to the clamping rod 24 by bolts, and the clamping plate 28 can be independently changed in thickness, shape and material according to the function of the clamping area of ​​different control levers, such as surface curvature and force requirements. This can realize the modular replacement of clamping components without replacing the entire fixture, which greatly shortens the changeover time.

[0042] Specifically, a through moving hole 231 is provided between the moving plate 21 and the moving block 23. A moving rod 232 is provided in the moving hole 231. A connecting plate 26 is provided on the moving rod 232. Movable rods 25 are hinged at both ends of the connecting plate 26. The two sets of movable rods 25 are respectively hinged to two sets of clamping rods 24.

[0043] In this embodiment, when clamping the car control lever, the moving rod 232 is pulled down, which causes the connecting plate 26 to descend. Through the hinge between the movable rod 25 and the clamping rod 24, the two sets of clamping rods 24 are moved toward the axis of the moving rod 232, so that the two sets of clamping plates 28 perform the clamping process on the car control lever.

[0044] Specifically, guide grooves 14 are provided on both sides of the adjustment groove 13, and guide plates 22 are provided at both ends of the moving plate 21. The two sets of guide plates 22 are slidably disposed in the two sets of guide grooves 14 respectively.

[0045] In this embodiment, the sliding engagement between the guide groove 14 and the guide plate 22 effectively constrains the degree of freedom of movement of the moving plate 21 within the adjustment groove 13, ensuring that the moving plate 21 can only make linear displacement along the length direction of the guide groove 14, eliminating the risk of radial offset, and ensuring that the displacement trajectory of the gripper 20 is accurate and controllable.

[0046] Specifically, the adjustment component 40 includes an adjustment block 41, the adjustment block 41 has an adjustment hole 43, and the placement rod 30 is disposed in multiple sets of adjustment holes 43.

[0047] Specifically, the outer wall of the placement rod 30 is provided with a threaded outer wall 33;

[0048] Adjusting nuts 42 are provided on both sides of the adjusting block 41. The adjusting nuts 42 are threadedly engaged with the threaded outer wall 33, so that the adjusting nuts 42 are threadedly sleeved on the outer wall of the placement rod 30.

[0049] In this embodiment, when the clamping claw 20 is moved to adjust its displacement, the wrench drives the adjusting nut 42 to rotate. The displacement of the two sets of adjusting nuts 42 drives the adjusting block 41 to move on the placement rod 30, so as to adapt to different lengths of car control rods.

[0050] Specifically, the placement plate 10 is provided with four sets of mounting rods 12, and the bottom end of the four sets of mounting rods 12 is provided with a fixing plate 11;

[0051] The placement rod 30 is provided with lifting plates 31 at both ends, and lifting sleeves 32 are provided at both ends of the lifting plates 31. The two sets of lifting sleeves 32 are slidably arranged on the two sets of mounting rods 12 on the same side.

[0052] Specifically, the fixing plate 11 has multiple sets of cylinder fixing holes 15, and the multiple sets of cylinder fixing holes 15 are matched with the positions of the two sets of lifting plates 31.

[0053] A lifting cylinder connected to the lifting plate 31 is provided on the cylinder fixing hole 15.

[0054] In this embodiment, when the placement rod 30 is driven to rise and fall, the lifting cylinder is connected to the cylinder fixing hole 15, and then the piston rod of the lifting cylinder is connected to the lifting plate 31. The placement rod 30 is driven to rise and fall by the lifting cylinder, thereby controlling multiple sets of clamping claws 20 to perform the clamping process at the same time.

[0055] 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.
