Description

Technical Field

[0001] This utility model relates to the field of automobile manufacturing technology, and in particular to a fixture for machining automobile pins. Background Technology

[0002] A pin clamp is a device specifically designed for clamping and positioning pins. It plays a crucial role in machining. Pin clamps can precisely position and hold pins, ensuring their stability and accuracy during machining, thereby improving machining precision and reducing errors. Pin clamps are mainly used to clamp and position pins during machining processes, ensuring the pins remain stable during drilling, milling, grinding, and other processes, thus improving machining accuracy and efficiency. They are widely used in the manufacturing and maintenance of machine tools, molds, automobiles, air conditioners, refrigerators, and other mechanical equipment.

[0003] Automotive pin machining fixtures are tooling equipment specifically designed for machining automotive pins. The main function of automotive pin machining fixtures is to fix and support the pins, ensuring normal operation during the machining process, so that the turned part meets the specified dimensions, ensuring that the machined pins meet the design requirements, and also helping to improve the automation level and processing speed of the production line.

[0004] Traditional fixtures for machining automotive pins require manual clamping, which not only increases the complexity of the work but also poses a risk of injury to workers. Furthermore, during operation, the clamping position may become unbalanced due to different material sizes, causing the material's center of gravity to shift and resulting in a dangerous situation of tool collision during the cutting process. Therefore, a new fixture for machining automotive pins is proposed. Utility Model Content

[0005] The purpose of this utility model is to solve the shortcomings of existing fixtures, such as cumbersome clamping process and small clamping range, and to propose a fixture for machining automotive pin shafts.

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

[0007] A fixture for machining automotive pins includes a guide plate and a mounting cylinder, which are fixedly connected. The top of the guide plate has multiple guide grooves that extend through the guide plate. Multiple clamping assemblies are provided on the guide plate, each clamping assembly including a clamping hydraulic cylinder and a clamping block. A rotating plate is rotatably connected to the inner side of the mounting cylinder. A drive assembly for the rotating plate is provided inside the mounting cylinder, the drive assembly including a motor, a gear disk, and a main gear.

[0008] The above technical solution further includes:

[0009] Guide blocks are slidably disposed on the inner side of the plurality of guide grooves, the guide blocks are fixedly connected to the clamping hydraulic cylinder, and the clamping hydraulic cylinder and the clamping blocks are rotatably connected.

[0010] The clamping block has a rotating groove on its outer side, and a slider is fixedly connected to the inner side of the clamping hydraulic cylinder. The slider is slidably connected to the rotating groove. Through the design of the rotating groove in the clamping assembly, the clamping block can clamp the material during the clamping process. When it is released, it will not block the material from being taken out. This improves the clamping stability and facilitates the removal and insertion of materials, reducing the complexity of the work.

[0011] The mounting cylinder is fixedly connected to the motor, and the motor is located inside the mounting cylinder. The output end of the motor is fixedly connected to the gear disk.

[0012] Multiple planetary gears mesh on the inner side of the gear disk, and these planetary gears mesh together with the main gear. A drive shaft is fixedly connected to the inner side of the main gear. The drive assembly allows the clamping block to move along the circumferential groove, which can increase the size range of the clamped material. The torque of the clamping block is increased by the main gear and multiple planetary gears, thereby improving the stability during the turning process.

[0013] The guide plate has a bearing groove on its inner side, and a bearing is fixedly connected to the inner side of the bearing groove. The bearing is fixedly connected to the drive shaft.

[0014] The drive shaft is fixedly connected to the rotating plate, and the rotating plate is rotatably connected to the guide plate.

[0015] The rotating plate has multiple circumferential grooves on the side near the gear disk. The number of circumferential grooves is the same as the number of guide grooves. The guide block is slidably connected to the circumferential grooves.

[0016] This utility model has the following beneficial effects:

[0017] 1. In this utility model, the design of the rotating groove in the clamping component allows the clamping block to fasten the material during the clamping process. When the material is released, it will not obstruct the removal of the material. This improves the clamping stability and facilitates the removal and insertion of materials, reducing the complexity of the work.

[0018] 2. In this utility model, the drive component allows the clamping block to move along the circumferential groove, which can increase the size range of the clamped material. The main gear and multiple planetary gears further increase the torque of the clamping block and improve the stability during the turning process. Attached Figure Description

[0025] 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.

[0026] Example 1

[0027] like Figures 1-5 As shown, the present invention proposes a fixture for machining automotive pin shafts, including a guide plate 1 and a mounting cylinder 2, which are fixedly connected. The top of the guide plate 1 is provided with multiple guide grooves 5, which pass through the guide plate 1. Multiple clamping components are provided on the guide plate 1, including a clamping hydraulic cylinder 3 and a clamping block 4. A rotating plate 11 is rotatably connected to the inner side of the mounting cylinder 2. A drive assembly for rotating the plate 11 is provided on the inner side of the mounting cylinder 2, including a motor 13, a gear disk 14, and a main gear 16.

[0028] Guide blocks 8 are slidably arranged on the inner side of multiple guide grooves 5. The guide blocks 8 are fixedly connected to the clamping hydraulic cylinder 3, and the clamping hydraulic cylinder 3 and the clamping blocks 4 are rotatably connected.

[0029] A rotating groove 10 is provided on the outer side of the clamping block 4, and a slider 9 is fixedly connected to the inner side of the clamping hydraulic cylinder 3. The slider 9 is slidably connected to the rotating groove 10.

[0030] The mounting cylinder 2 is fixedly connected to the motor 13, and the motor 13 is located inside the mounting cylinder 2. The output end of the motor 13 is fixedly connected to the gear disk 14.

[0031] In this embodiment, during use, for cylindrical materials, the bottom protrusion of the material is placed on the guide plate 1. Then, by controlling the rotation of the motor 13, the rotation of the motor 13 drives the rotation of the gear disk 14. The rotation of the gear disk 14 drives multiple planetary gears 15 to move in a circular motion along the gear disk 14. Subsequently, the movement of the multiple planetary gears 15 drives the rotation of the main gear 16. The rotation of the main gear 16 drives the rotation of the transmission shaft 7. The rotation of the transmission shaft 7 drives the rotation of the circumferential groove 12. At the same time, the guiding effect of the multiple circumferential grooves 12 and the limiting effect of the multiple guide grooves 5 are used to make the guide block 8 move along the guide groove 5 during the rotation of the circumferential grooves 12, thereby adjusting the distance between the multiple clamping hydraulic cylinders 3. For materials of different sizes, stable clamping can be achieved. In the above process, the clamping block 4 moves along the guide groove 5, which can improve the size range of the clamped material. The torque of the clamping block is increased by setting the main gear 16 and multiple planetary gears 15, thereby improving the stability during the turning process.

[0032] Example 2

[0033] like Figures 1-5 As shown, based on Embodiment 1, multiple planetary gears 15 mesh with the inner side of the gear disk 14, and the multiple planetary gears 15 mesh with the main gear 16. A transmission shaft 7 is fixedly connected to the inner side of the main gear 16.

[0034] A bearing groove 17 is provided on the inner side of the guide plate 1, and a bearing 6 is fixedly connected to the inner side of the bearing groove 17. The bearing 6 is fixedly connected to the drive shaft 7.

[0035] The drive shaft 7 is fixedly connected to the rotating plate 11, and the rotating plate 11 is rotatably connected to the guide plate 1;

[0036] The rotating plate 11 has multiple circumferential grooves 12 on the side near the gear disk 14. The number of circumferential grooves 12 is the same as the number of guide grooves 5. The guide block 8 is slidably connected to the circumferential grooves 12.

[0037] In this embodiment, when the material is T-shaped, the extension and retraction of the clamping block 4 are controlled by the hydraulic principle. When the material is placed on the guide plate 1, hydraulic oil is injected into the inside of the clamping hydraulic cylinder 3 by the hydraulic principle. At this time, the clamping block 4 will rotate and extend along the rotating groove 10 and the clamping hydraulic cylinder 3, guided by the rotating groove 10. The rotation and extension of the clamping block 4 allows it to clamp the protrusion at the bottom of the T-shaped platform. At the same time, for T-shaped objects of different sizes, the same process is used. The distance between multiple clamping blocks 4 is adjusted by controlling the rotation of the motor 13. In the above process, through the design of the rotating groove 10, the clamping block 4 can clamp the material during the clamping process. When it is released, it will not block the removal of the material. This improves the clamping stability and facilitates the removal and placement, reducing the complexity of the work.

[0038] 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.
