Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically a clamping and positioning device for manufacturing pins. Background Technology

[0002] In the manufacturing process of pins, clamping and positioning devices are crucial equipment for ensuring machining accuracy and efficiency. Traditional clamping devices typically employ simple mechanical clamping methods, such as manual bolt clamping or hydraulic clamping, which have several drawbacks. For example, manual clamping is cumbersome, inefficient, and the clamping force is difficult to control precisely, easily leading to pin displacement during machining and affecting machining accuracy. While hydraulic clamping can provide greater clamping force, the equipment is complex, costly, and requires extremely high sealing and stability from the hydraulic system; leaks or malfunctions will severely impact production progress. Furthermore, most existing clamping devices lack flexible positioning and adjustment functions, failing to adapt to pins of different sizes and shapes, thus limiting their application in diversified production. Therefore, developing a clamping and positioning device that is simple in structure, easy to operate, provides precise positioning, and can adapt to various pins is of great significance for improving the manufacturing quality and production efficiency of pins. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model relates to a clamping and positioning device for manufacturing pins. This device has a simple and reliable structure, effectively solves the aforementioned technical problems, and is suitable for widespread use. To achieve the above objectives, this utility model is implemented through the following technical solution:

[0004] A clamping and positioning device for manufacturing pins includes a motor, a support plate, a drive gear, a first driven gear, a second driven gear, a rotating gear, and a first clamping plate. The two support plates are arranged opposite each other. The housing of the motor is fixedly connected to the rear support plate. The output shaft of the motor passes through the support plate and is connected to the drive gear. The drive gear is located between the two support plates. The first driven gear, the second driven gear, and the rotating gear are rotatably arranged between the two support plates via support shafts. The drive gear meshes with the first driven gear and the rotating gear, respectively. The rotating gear also meshes with the second driven gear. When the drive gear rotates, it drives the first driven gear and the second driven gear to rotate synchronously.

[0005] The top of the support plate has an inward protrusion, and two first clamping plates are symmetrically arranged on the left and right. Each first clamping plate has a track at its bottom. The front and rear limiting grooves of the track are slidably engaged with the protrusions of the two support plates. The bottom of the track has a rack. The racks of the two first clamping plates mesh with the first driven gear and the second driven gear located below. The rotation of the first driven gear and the second driven gear causes the racks they mesh with to move along the straight direction of the track. Each first clamping plate has an arc-shaped limiting groove on one side.

[0006] Based on the above scheme and as a preferred embodiment of the above scheme: each of the first clamping plates is further provided with a corresponding second clamping plate on its front side, and the second clamping plate and the first clamping plate are connected by a spacing adjustment component, which is used to adjust the spacing between the second clamping plate and the first clamping plate.

The first clamping plate is provided with a threaded hole that runs through the front and rear. The screw is threadedly connected to the threaded hole. The front end of the screw is provided with a smooth rod portion. The smooth rod portion passes through the through hole of the second clamping plate and is fixedly connected to the limiting block. The diameter of the limiting block is larger than the diameter of the smooth rod portion. The rear end of the screw is provided with a gear-shaped knob. A telescopic rod is also provided between the first clamping plate and the second clamping plate.

[0008] Based on the above scheme and as a preferred embodiment of the above scheme: the first clamping plate has an inclined surface on the side away from the arc groove.

[0009] Based on the above scheme and as a preferred embodiment of the above scheme: two support plates are fixedly connected by bolt assembly, and a positioning support block is provided between the two support plates. The positioning support block is located at the bottom of the support plate, and the front and rear of the positioning support block respectively abut against and fit against the inner surfaces of the two support plates.

[0010] The outstanding and beneficial technical effect of this invention compared with the prior art is that the clamping and positioning device for manufacturing pins of this invention achieves efficient and precise clamping and positioning of pins through a motor-driven gear transmission system.

[0011] Its unique double-clamp design, combined with a spacing adjustment component, can flexibly adapt to pins of different sizes and shapes, significantly improving the versatility and applicability of the clamping device. Furthermore, by replacing traditional manual or hydraulic clamping methods with motor drive, operation is not only more convenient and faster, but it also effectively avoids uneven or unstable clamping force caused by human error or hydraulic system malfunctions, thereby significantly improving the precision and quality of pin machining.

[0020] Example 1

[0021] To solve the above technical problems, such as Figure 1-2As shown, this embodiment designs a clamping and positioning device for pin manufacturing, including a motor 1, a support plate 2, a driving gear 3, a first driven gear 4, a second driven gear 5, a rotating gear 6, and a first clamping plate 7. The two support plates 2 are arranged opposite each other. The housing of the motor 1 is fixedly connected to the rear support plate 2. The output shaft of the motor 1 passes through the support plate 2 and is connected to the driving gear 3. The driving gear 3 is located between the two support plates 2. The first driven gear 4, the second driven gear 5, and the rotating gear 6 are rotatably arranged between the two support plates 2 through support shafts. The driving gear 3 meshes with the first driven gear 4 and the rotating gear 6 respectively. The rotating gear 6 also meshes with the second driven gear 5. When the driving gear 3 rotates, it drives the first driven gear 4 and the second driven gear 5 to rotate synchronously. Using the motor 1 as a power source, it can provide stable and controllable power output. The speed and direction of motor 1 can be precisely adjusted by the controller, thereby achieving flexible control of clamping speed and clamping force. Compared with traditional manual or hydraulic clamping methods, motor 1 drive is not only more convenient to operate, but also avoids the problem of uneven clamping force caused by human factors, significantly improving the stability and reliability of clamping. Gear transmission has the characteristics of high precision and high efficiency, which can ensure the synchronization and accuracy of clamping action. At the same time, the self-locking performance of gear transmission can also prevent the clamping plate from loosening due to external force during the clamping process, further enhancing the stability of clamping.

[0022] The support plate 2 has an inwardly protruding part 9 on its top. Two first clamping plates 7 are symmetrically arranged on the left and right. Each first clamping plate 7 has a track 8 at its bottom. The front and rear limiting grooves of the track 8 are respectively slidably engaged with the protruding parts 9 of the two support plates 2. The bottom of the track 8 has a rack 10. The racks 10 of the two first clamping plates 7 are respectively engaged with the first driven gear 4 and the second driven gear 5 located below. The rotation of the first driven gear 4 and the second driven gear 5 causes the racks 10 engaged with each other to move along the straight direction of the track 8. Each first clamping plate 7 has an arc-shaped limiting groove on one side. The design of the track 8 and its sliding engagement with the protruding parts 9 of the support plate 2 provide precise guidance and limiting for the movement of the clamping plates. The front and rear limiting grooves of the track 8 can effectively prevent the clamping plates from deviating during movement, ensuring the straightness and stability of the clamping action. In addition, the engagement of the rack 10 at the bottom of the track 8 with the gears further enhances the precision control of the movement of the clamping plates, allowing the clamping position to be finely adjusted as needed to meet the processing requirements of pins of different sizes.

[0023] In this embodiment, it is further preferred that the first clamping plate 7 has an inclined surface on the side away from the arc groove, so that the clamping plate is approximately triangular. The triangular structure has natural stability because its three corners can evenly distribute the force, reducing deformation or tilting caused by excessive local force.

[0024] In this embodiment, it is further preferred that the two support plates 2 are fixedly connected by bolt assembly 11, and a positioning support block 17 is provided between the two support plates 2. The positioning support block 17 is located at the bottom of the support plate 2, and the front and rear of the positioning support block 17 abut against the inner surfaces of the two support plates 2 respectively. The setting of the positioning support block 17 can effectively prevent the support plates 2 from shifting or deforming during use. This design ensures that the relative position between the support plates 2 is always maintained. The use of bolt assembly 11 makes the installation and disassembly of the support plates 2 more convenient. Users can quickly complete the fixing or disassembly of the support plates 2 with simple tools, thereby improving maintenance efficiency and maintaining stability.

[0025] Example 2

[0026] In the manufacturing process of pins, the length of the first clamping plate 7 is usually limited by the structural design, making it difficult to meet the clamping requirements of longer pins. If only the first clamping plate 7 is used for clamping, longer pins may not be able to be stably positioned due to insufficient contact area, and may even loosen or shift during processing, thus affecting processing accuracy and quality.

[0027] To address this technical problem, this embodiment is further modified based on the above embodiments, such as... Figure 3 , 4 As shown, each of the first clamping plates 7 also has a corresponding second clamping plate 12 on its front side. The second clamping plate 12 is connected to the first clamping plate 7 via a spacing adjustment assembly, which is used to adjust the spacing between the second clamping plate 12 and the first clamping plate 7. By setting the second clamping plate 12, the contact area between the clamping device and the pin can be significantly increased. The second clamping plate 12 works in conjunction with the first clamping plate 7 to ensure that both ends of a longer pin can be stably clamped, thereby compensating for the problem of insufficient length of the first clamping plate 7 itself. The introduction of the second clamping plate 12 allows the clamping force to be evenly distributed at both ends of the pin, avoiding instability caused by the clamping force being concentrated at one end of the pin. This design ensures the stability of the longer pin during the processing and improves the processing accuracy.

[0028] In this embodiment, it is further preferred that the spacing adjustment assembly includes a screw 13, a telescopic rod 14, and a limiting block 15. The first clamping plate 7 is provided with a threaded hole that runs through the front and rear. The screw 13 is threadedly connected to the threaded hole. The front end of the screw 13 is provided with a smooth rod portion. The smooth rod portion passes through the through hole of the second clamping plate 12 and is fixedly connected to the limiting block 15. The diameter of the limiting block 15 is larger than the diameter of the smooth rod portion. The rear end of the screw 13 is provided with a gear-shaped knob 16. A telescopic rod 14 is also provided between the first clamping plate 7 and the second clamping plate 12. Since the smooth rod portion and the through hole are in a rotational fit, when the screw 13 rotates, the smooth rod portion will not drive the second clamping plate 12 to rotate together. Instead, the rotational motion is converted into linear motion through the threaded fit between the screw 13 and the threaded hole of the first clamping plate 7. This design cleverly utilizes the principle of threaded transmission to achieve linear movement of the second clamping plate 12. By rotating the gear-shaped knob 16 of the screw 13, the user can precisely control the movement distance of the second clamping plate 12. The thread pitch determines the distance the second clamping plate 12 moves with each rotation of the screw 13, thus achieving high-precision pitch adjustment. This precise control capability is crucial for adapting to pins of different lengths, ensuring the versatility and flexibility of the clamping device.

[0029] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made by those skilled in the art based on the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
