Description

Technical Field

[0001] This utility model belongs to the field of pressure sleeve tooling processing technology, and specifically relates to a positioning structure for pressure sleeve tooling. Background Technology

[0002] The positioning structure of a press-fit fixture is a crucial aspect of fixture design, designed to ensure the workpiece maintains accurate positioning and a stable state during the press-fitting process. This positioning structure is particularly critical when dealing with precision parts, complex shapes, or workpieces requiring high precision. A well-designed positioning structure can effectively improve production efficiency, reduce workpiece scrap rates, and ensure machining quality and accuracy.

[0003] Chinese patent publication number CN217257802U discloses a positioning structure for a resin compaction fixture, including a positioning base, a limiting seat installed on the upper side of the positioning base, a limiting pad installed on the upper end of the positioning base located on the side of the limiting seat, and a compaction fixture body disposed on the upper end of the positioning base located inside the limiting seat. In this positioning structure for a resin compaction fixture, the compaction fixture body is placed on the limiting seat and the limiting seat, and rotating the adjusting handle drives the adjusting threaded rod to rotate, thereby pushing the locking block to contact the side of the compaction fixture body, thus fixing and positioning the compaction fixture body. Simultaneously, the limiting seat and positioning fixing components are installed on the positioning base through mounting holes evenly distributed on the surface of the positioning base, facilitating the installation of the limiting seat and positioning fixing components in different positions, making it easy to adjust the positioning position of the fixture. The assembly and disassembly are convenient and quick, offering good flexibility and greatly improving practicality.

[0004] However, the current processing of press sleeve tooling has the following problems: the positioning device for workpiece processing mentioned above is difficult to apply to workpieces of different shapes. Therefore, we propose a positioning structure for press sleeve tooling. Utility Model Content

[0005] The purpose of this invention is to provide a positioning structure for a press sleeve tooling, which can solve the problem that positioning devices for workpieces during processing in related technologies are difficult to apply to workpieces of different shapes.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A positioning structure for a press sleeve tooling includes a worktable, a support leg fixedly connected to the bottom of the worktable, a placement platform fixedly connected to the top of the worktable, and a positioning device provided on the top of the worktable.

[0008] The positioning device includes a motor, the top of which is fixedly connected to the bottom of the worktable. The output shaft of the motor is fixedly connected to a rotating shaft. A bevel gear is fixedly connected to the front side of the rotating shaft. A support plate is fixedly connected to the side of the worktable. A bidirectional threaded rod is rotatably connected to the side of the support plate. A bevel gear is fixedly connected to the circumferential surface of the bidirectional threaded rod. A threaded sleeve is threadedly connected to the circumferential surface of the bidirectional threaded rod. A connecting strip is fixedly connected to the circumferential surface of the threaded sleeve. A positioning pin is slidably connected to the inner wall of a hollow block on the side of the connecting strip.

[0009] A limiting groove is provided on the top of the workbench, and the outer surface of the connecting strip is slidably connected to the inner wall of the limiting groove. The function of the limiting groove is to restrict the movement trajectory of the threaded sleeve by using the connecting strip when the threaded sleeve moves with the connecting strip.

[0010] A flexible spring is fixedly connected to the inner wall of the hollow block. The end of the flexible spring away from the hollow block is fixedly connected to the side of the positioning pin. The function of the flexible spring is to drive the positioning pin to reset when positioning is not required.

[0011] The circumferential surface of bevel gear one meshes with the circumferential surface of bevel gear two. The number of positioning pins and flexible springs is set to several, and they are arranged linearly along the vertical central axis of the hollow block. The number of threaded sleeves, connecting strips, hollow blocks, positioning pins, limiting grooves and flexible springs is set to two, and they are symmetrical to each other along the vertical central axis of the bidirectional threaded rod. The purpose of the circumferential surface of bevel gear one meshing with the circumferential surface of bevel gear two is to drive bevel gear two to rotate when bevel gear one rotates.

[0012] The top of the workbench is equipped with a feeding device, which includes a hydraulic cylinder. The bottom of the hydraulic cylinder is fixedly connected to the top of the workbench. One end of the hydraulic cylinder is slidably connected to a force rod through a piston. The other end of the hydraulic cylinder is slidably connected to a hydraulic rod through another piston. A push plate is fixedly connected to the front side of the hydraulic rod. A collection box is provided on the inner wall of the workbench. The function of the push plate is to feed the finished tooling.

[0013] A return spring is fixedly connected to the circumferential surface of the force-bearing rod. The end of the return spring away from the force-bearing rod is fixedly connected to the side of the hydraulic cylinder. The function of the return spring is to allow the force-bearing rod to reset when the connecting bar stops pushing it.

[0014] The side of the force-bearing rod is located on the displacement trajectory of the connecting bar, and the top of the collection box is located below the push plate. The purpose of the side of the force-bearing rod being located on the displacement trajectory of the connecting bar is to push the force-bearing rod when the connecting bar moves.

[0015] The technical effects achieved by this utility model are as follows:

[0016] 1. This utility model, through the setting of a positioning device, enables the hollow block to move by the connecting strip when the threaded sleeve moves towards the center. When the hollow block moves, it can drive the positioning pin to move. When the positioning pin moves, it can contact the workpiece. When the positioning pin contacts the workpiece, it will move into the hollow block due to the pressure of the workpiece. The positioning pin will continue to move into the hollow block until it can no longer move, thus completing the positioning of the workpiece. The setting of multiple positioning pins and flexible springs can better position the workpiece and can position workpieces of different shapes.

[0017] 2. The present invention, through the setting of the feeding device, causes the force rod to move into the hydraulic cylinder when it is squeezed by the connecting bar. As the force rod moves into the hydraulic cylinder, the hydraulic rod moves out of the hydraulic cylinder due to the squeezing force of the force rod. When the hydraulic rod moves, it can drive the push plate to move, so that when the push plate moves, it can push the workpiece processed on the placement table, and then the workpiece is pushed into the collection box to complete the feeding.

[0025] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0026] like Figure 1-5 As shown, a positioning structure for a press sleeve tooling includes a worktable 1, a support leg 2 fixedly connected to the bottom of the worktable 1, a placement platform 3 fixedly connected to the top of the worktable 1, and a positioning device 4 provided on the top of the worktable 1.

[0027] The positioning device 4 includes a motor 41, the top of which is fixedly connected to the bottom of the worktable 1. The output shaft of the motor 41 is fixedly connected to a rotating shaft 42. A bevel gear 43 is fixedly connected to the front side of the rotating shaft 42. A support plate 44 is fixedly connected to the side of the worktable 1. A bidirectional threaded rod 45 is rotatably connected to the side of the support plate 44. A bevel gear 46 is fixedly connected to the circumferential surface of the bidirectional threaded rod 45. A threaded sleeve 47 is threadedly connected to the circumferential surface of the bidirectional threaded rod 45. A connecting strip 48 is fixedly connected to the circumferential surface of the threaded sleeve 47. A positioning pin 410 is slidably connected to the inner wall of a hollow block 49 fixedly connected to the side of the connecting strip 48.

[0028] A limiting groove 411 is provided on the top of the workbench 1. The outer surface of the connecting bar 48 is slidably connected to the inner wall of the limiting groove 411. The function of the limiting groove 411 is to limit the movement trajectory of the threaded sleeve 47 by using the connecting bar 48 when the threaded sleeve 47 moves the connecting bar 48.

[0029] A flexible spring 412 is fixedly connected to the inner wall of the hollow block 49. The end of the flexible spring 412 away from the hollow block 49 is fixedly connected to the side of the positioning pin 410. The function of the flexible spring 412 is to drive the positioning pin 410 to reset when positioning is not required.

[0030] The circumferential surface of bevel gear 43 meshes with the circumferential surface of bevel gear 46. The number of positioning pins 410 and flexible springs 412 are set to several, and they are arranged linearly along the vertical central axis of the hollow block 49. The number of threaded sleeves 47, connecting bars 48, hollow blocks 49, positioning pins 410, limiting grooves 411 and flexible springs 412 are set to two, and they are symmetrical to each other along the vertical central axis of the bidirectional threaded rod 45. The function of the circumferential surface of bevel gear 43 meshing with the circumferential surface of bevel gear 46 is to drive bevel gear 46 to rotate when bevel gear 43 rotates.

[0031] Based on the above structure, firstly, when the device is needed to process a workpiece, the positioning device 4 can be used to fix the workpiece. By starting the motor 41, when the output shaft of the motor 41 rotates, it can drive the rotating shaft 42 to rotate. When the rotating shaft 42 rotates, it can drive the first bevel gear 43 to rotate. When the first bevel gear 43 rotates, it can drive the second bevel gear 46 to rotate. Thus, when the second bevel gear 46 rotates, it can drive the bidirectional threaded rod 45 to rotate on the support plate 44. Furthermore, when the bidirectional threaded rod 45 rotates, it can drive the two threaded sleeves 47 to move towards the middle. When the threaded sleeves 47 move towards the middle... During movement, the hollow block 49 can be moved by the connecting strip 48. When the hollow block 49 moves, it can move the positioning pin 410. When the positioning pin 410 moves, it can contact the workpiece. When the positioning pin 410 contacts the workpiece, it will move into the hollow block 49 due to the pressure of the workpiece. The positioning pin 410 will continue to move into the hollow block 49 until it can no longer move, thus completing the positioning of the workpiece. The arrangement of multiple positioning pins 410 and flexible springs 412 can better position the workpiece and can position workpieces of different shapes.

[0032] like Figure 1-5 As shown, a feeding device 5 is provided on the top of the workbench 1. The feeding device 5 includes a hydraulic cylinder 51. The bottom of the hydraulic cylinder 51 is fixedly connected to the top of the workbench 1. A force rod 52 is slidably connected to one end of the hydraulic cylinder 51 through a piston. A hydraulic rod 53 is slidably connected to the other end of the hydraulic cylinder 51 through another piston. A push plate 54 is fixedly connected to the front and side of the hydraulic rod 53. A collection box 55 is provided on the inner wall of the workbench 1. The function of the push plate 54 is to feed the finished tooling.

[0033] A return spring 56 is fixedly connected to the circumferential surface of the force-bearing rod 52. The end of the return spring 56 away from the force-bearing rod 52 is fixedly connected to the side of the hydraulic cylinder 51. The function of the return spring 56 is to allow the force-bearing rod 52 to be reset when the connecting bar 48 stops pushing it.

[0034] The side of the force-bearing rod 52 is located on the displacement trajectory of the connecting bar 48, and the top of the collection box 55 is located below the push plate 54. The purpose of the side of the force-bearing rod 52 being located on the displacement trajectory of the connecting bar 48 is to push the force-bearing rod 52 when the connecting bar 48 moves.

[0035] According to the above structure, the movement of the connecting bar 48 can drive the unloading device 5. When the workpiece is processed, the connecting bar 48 will separate to both sides through the threaded sleeve 47 and squeeze the force rod 52. When the force rod 52 is squeezed by the connecting bar 48, it will move into the hydraulic cylinder 51. When the force rod 52 moves into the hydraulic cylinder 51, the hydraulic rod 53 will move out of the hydraulic cylinder 51 due to the squeezing force of the moving force rod 52. When the hydraulic rod 53 moves, it can drive the push plate 54 to move, so that when the push plate 54 moves, it can push the processed workpiece on the placement table 3, and then the workpiece is pushed into the collection box 55 to complete the unloading.

[0036] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
