[0002] Nowadays, with continuous product innovation, the shape and structure of sleeves are becoming more and more complex. Traditional positioning fixtures are difficult to effectively position and clamp these complex-shaped sleeves, and special positioning fixtures need to be developed to meet their processing requirements.

[0003] A spindle sleeve inner hole machining fixture with authorization announcement number CN222660865U includes a base plate, a fixing mechanism on the top of the base plate for clamping the sleeve, an adjustment mechanism in the inner cavity of the fixing mechanism for adjusting the clamping position, mounting blocks fixedly connected to both sides of the base plate, mounting bolts threadedly connected to the inner cavity of the mounting blocks, and a vertical plate including a vertical plate, a hydraulic cylinder threadedly connected to the inner cavity of the vertical plate, a movable plate fixedly connected to the piston rod of the hydraulic cylinder, and a fixed connection between the bottom of the vertical plate and the top of the base plate. This fixture has a fixed clamping position, which makes it difficult to meet the requirements of full welding processing of the outer surface of the sleeve, resulting in blind spots in the processing.

[0004] To address the aforementioned problems, a positioning fixture for sleeve machining is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a positioning fixture for sleeve processing, which solves the problem in the background art that the existing fixtures have fixed clamping positions, making it difficult to meet the full welding processing requirements of the outer surface of the sleeve, resulting in blind spots in the processing.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a positioning fixture for sleeve processing, comprising an adjusting mechanism, wherein a driving mechanism is movably sleeved at the output end of the adjusting mechanism, the driving mechanism is provided in two sets, and clamping mechanisms are rotatably arranged on both sides of the driving mechanism, with one set of the driving mechanism correspondingly connected to four sets of clamping mechanisms, the adjusting mechanism comprising a rotatably arranged bidirectional threaded rod, the driving mechanism being sleeved on the bidirectional threaded rod, the driving mechanism comprising a fixed plate, driven wheels rotatably arranged on both sides of the fixed plate, and steering wheels meshing at both ends of one driven wheel, the clamping mechanism comprising two sets of rotating rods meshing on one side of the steering wheel, and two sets of rotating rods meshing on one side of the driven wheel, the two sets of steering wheels being axially symmetrically arranged.

[0016] 1. The present invention provides a positioning fixture for sleeve processing. By adjusting the setting of the mechanism, the rotation of the bidirectional threaded rod drives two sets of drive mechanisms to move in opposite directions to adjust the position, so as to achieve double-sided fixation of the sleeve and initially solve the problem of welding stability of the sleeve.

[0017] 2.

The reversal of the driven wheel can realize the staggered replacement of the clamping points of the clamping mechanism, which meets the full welding requirements of the sleeve. It solves the problem that the existing fixtures have fixed clamping positions, which make it difficult to meet the full welding processing requirements of the outer surface of the sleeve, resulting in blind spots in the processing.

[0023] 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.

[0024] To further understand the content of this utility model, a detailed description of this utility model will be provided in conjunction with the accompanying drawings.

[0025] Combination Figure 1 This utility model discloses a positioning fixture for sleeve processing, comprising an adjusting mechanism 1, a driving mechanism 2 movably sleeved at the output end of the adjusting mechanism 1, two sets of driving mechanisms 2, and clamping mechanisms 3 rotatably arranged on both sides of the driving mechanism 2, with one set of driving mechanisms 2 correspondingly connected to four sets of clamping mechanisms 3. The adjusting mechanism 1 includes a rotatably arranged bidirectional threaded rod 13, the driving mechanism 2 being sleeved on the bidirectional threaded rod 13, the driving mechanism 2 including a fixed plate 21, driven wheels 23 rotatably arranged on both sides of the fixed plate 21, and steering wheels 231 meshing at both ends of one side of the driven wheel 23. The clamping mechanism 3 includes two sets of rotating rods 31 meshing on one side of the steering wheel 231, and two sets of rotating rods 31 meshing on one side of the driven wheel 23, with the two sets of steering wheels 231 arranged symmetrically.

[0026] Specifically, the rotation of the bidirectional threaded rod 13 drives the two sets of drive mechanisms 2 to move in opposite directions to adjust their positions, thereby fixing the sleeve on both sides. The rotation of the driven wheel 23 drives the two sets of rotating rods 31 set on one side of the fixed plate 21 to adjust their angles in the same direction. The setting of the steering wheel 231 allows the rotating rods 31 on both sides of the fixed plate 21 to adjust their angles in opposite directions to achieve clamping. The reversal of the driven wheel 23 can realize the staggered replacement of the clamping points of the clamping mechanism 3, meeting the full welding requirements of the sleeve.

[0027] The present invention will be further described below with reference to the embodiments.

[0028] Example 1:

[0029] Combination Figures 2-4 The adjustment mechanism 1 includes a U-shaped part 11, on which a slide rod 12 is fixedly mounted. The U-shaped part 11 is used to connect the slide rod 12, and the slide rod 12 realizes the sliding connection of the drive mechanism 2.

[0030] A motor component 14 is fixedly installed at one end of the U-shaped part 11, and a bidirectional threaded rod 13 is installed at the output end of the motor component 14. The motor component 14 drives the bidirectional threaded rod 13 to rotate to realize the opposite adjustment of the drive mechanism 2, and the slide rod 12 realizes the sliding limit of the drive mechanism 2.

[0031] The drive mechanism 2 also includes a clamping motor 22 fixedly mounted on one side of the fixed plate 21. The output end of the clamping motor 22 is connected to a drive wheel 221. The clamping motor 22 drives the drive wheel 221 to rotate, thereby realizing the drive adjustment of the clamping mechanism 3.

[0032] Driven wheel 23 and driving wheel 221 are meshed together. The two sets of driven wheels 23 on both sides of the fixed plate 21 rotate synchronously, thereby realizing the synchronous adjustment of the four sets of rotating rods 31.

[0033] One side of the fixed plate 21 is configured with a rotating rod 31, a driven wheel 23, and the rotating rod 31 meshing in sequence, while the other side is configured with the rotating rod 31, a steering wheel 231, a driven wheel 23, a steering wheel 231, and the rotating rod 31 meshing with each other. This structure enables the rotating rods 31 on both sides of the fixed plate 21 to rotate in opposite directions, thereby achieving the replacement of the clamping point.

[0034] Example 2:

[0035] Combination Figure 3 and Figure 4 The clamping mechanism 3 also includes a connecting rod 32 rotatably disposed on one side of the fixed plate 21. A gripper 33 is connected between the rotating rod 31 and the connecting rod 32. The gripper 33 adjusts the clamping angle and clamping force under the combined action of the connecting rod 32 and the rotating rod 31.

[0036] One side of the rotating rod 31 is provided with a half tooth 311 that meshes with the driven wheel 23, and the other side is provided with a limiting arc 312. The setting of the limiting arc 312 restricts the rotation adjustment of the driven wheel 23, and the setting of the half tooth 311 ensures that the rotating rod 31 can mesh with the driven wheel 23 to achieve rotation control.

[0037] One end of the gripper 33 is provided with a rubber part 333. The transition point between the gripper 33 and the rotating rod 31 is the first transition point 331, and the transition point between the connecting rod 32 and the gripper 33 is the second transition point 332. The rubber part 333 increases the gripping friction between the clamping mechanism 3 and the sleeve, thereby enhancing the stability of the positioning fixture.
