Description

Technical Field

[0001] This utility model relates to the field of cold heading machine manufacturing technology, and in particular to a power mechanism for a clamp longitudinally rotating 90° device. Background Technology

[0002] A cold heading machine is a device that cuts and cold-extrudes various processed metal wires, forming them into shapes within a mold. It is used to process various standard or non-standard fasteners. The clamping mechanism is the workpiece transfer mechanism within the cold heading machine's clamping system. When a workpiece is transferred from one station to the next, the clamps can open and close and rotate 180°, accurately transferring the workpiece from one station to the next, completing the workpiece reversal process. To process the side of the workpiece, the clamps need to be able to rotate the workpiece 90 degrees.

[0003] For example, Chinese Patent Publication (Announcement) No.: CN104190843A, patent title: Cold Heading Machine Clamp Piece Outward Flipping Mechanism, it discloses the technical solution of "

[0004] The present invention is implemented by the following technical solution: Cold Heading Machine Clamp Piece Outward Flipping Mechanism, including multiple feeding clamps that move back and forth in front of the cold heading machine bottom mold base, the lower end of the clamps are left and right jaws that can open or close, characterized in that: at least one clamp... when the flipping cam flips outward, it drives the clamp piece to flip outward" and achieves the technical effect of "

[0003] In view of the shortcomings of the background technology, the purpose of the present invention is to provide a cold heading machine clamp piece outward flipping mechanism that can realize the workpiece flipping outward by 90 degrees in the cold heading process, so that the workpiece can be upset in two mutually perpendicular directions, thereby greatly expanding the application space of the cold heading machine".

[0004] When processing two mutually perpendicular surfaces, it needs to move from the cold heading station M to the cold heading station N. That is, it cannot perform the cold heading process on two mutually perpendicular surfaces at the same station, resulting in low work efficiency. Therefore, the market urgently needs a device that can complete the cold heading process on two mutually perpendicular surfaces at the same station, as well as a mechanism that provides power to this device. Utility Model Content

[0005] The purpose of this utility model is to provide a power mechanism for a clamp that can be rotated 90° longitudinally, so as to solve the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical measures: a power mechanism for a clamp longitudinally rotating 90° device, characterized in that: it includes a rocker arm, one end of which provides initial power to the clamp longitudinally rotating 90° device; the other end of the rocker arm is hinged to a connecting rod; the other end of the connecting rod is hinged to a swing arm; the other end of the swing arm is fixedly connected to a drive wheel; the drive wheel meshes with a gear shaft to transmit power; the other end of the gear shaft is provided with a bearing; the bearing is driven by a rotating cam; the rotating cam is fixedly mounted on a transmission shaft; and one end of the transmission shaft is provided with a bevel gear that provides initial power.

[0007] Compared with existing technologies, the advantages of this invention are as follows: by adding a flipping cam to the existing transmission shaft, which drives a gear shaft via a bearing, the gear shaft drives a drive wheel on the rocker arm, and through a planar linkage mechanism composed of the rocker arm, connecting rod, and rocker arm, the rocker arm can ultimately produce a 90° swing amplitude back and forth. This new structure is simple and practical.

[0008] As an improvement of this utility model, a rack is provided at one end of the gear shaft, and a gear meshing with the rack is provided on the drive wheel. The purpose of this design is that the meshing transmission of the rack and gear can achieve good transmission smoothness, which is suitable for applications requiring long stroke and high load. In addition, since the position of the meshing line does not change, high precision and reliability of transmission can be guaranteed.

[0009] As an improvement of this utility model, a copper sleeve is provided around the gear shaft, and a shaft seat is provided around the copper sleeve. The purpose of this design is that the copper sleeve, as a friction-reducing element, can reduce the friction of the gear shaft, thereby extending the service life of the gear shaft. Secondly, the copper sleeve provides a stable support for the gear shaft, ensuring the concentricity and straightness of the gear shaft during operation, and improving the stability of the entire transmission.

[0010] As an improvement of this utility model, an anti-rolling surface is provided on the gear shaft. The purpose of this design is that, since the anti-rolling surface is a plane, it is constrained by the plane of the shaft seat, thus preventing the cylindrical gear shaft from turning over.

[0011] As an improvement of this utility model, the bearing is a needle roller bearing. The purpose of choosing this design is that, due to its compact structure, high load-bearing capacity, high-speed operation adaptability, and strong durability, needle roller bearings can withstand large impact loads and radial loads, making them more suitable for cam-driven scenarios.

[0019] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0020] Example 1

[0021] Please refer to Figure 1 -4.

[0022] This embodiment provides a power mechanism for a clamp longitudinally rotating 90° device, which is installed on the body 25 of a cold heading machine. The entire power mechanism includes a rocker arm 1. One end of the rocker arm 1 provides initial power to the clamp longitudinally rotating 90° device. The other end of the rocker arm 1 is hinged to a connecting rod 2. The other end of the connecting rod 2 is hinged to a swing rod 3. The other end of the swing rod 3 is fixedly connected to a drive wheel 4. The drive wheel 4 meshes with a gear shaft 5 to transmit power. The other end of the gear shaft 5 is provided with a bearing 6. The bearing 6 is driven by a rotating cam 7. The rotating cam 7 is fixedly installed on a transmission shaft 8. One end of the transmission shaft 8 is provided with a bevel gear 9 that provides initial power.

[0023] In the embodiments of this utility model application, please refer to Figure 3A rack 10 is provided at one end of the gear shaft 5, and a spur gear 11 that meshes with the rack 10 is provided on the drive wheel 4. This meshing transmission between the rack 10 and the spur gear 11 can achieve good transmission smoothness, which is suitable for applications that require long stroke and high load. In addition, since the position of the meshing line does not change, high precision and reliability of transmission can be guaranteed.

[0024] In the embodiments of this utility model application, please refer to Figure 4 A copper sleeve 12 is provided around the gear shaft 5, and a shaft seat 13 is provided around the copper sleeve 12. The copper sleeve 12 acts as a friction-reducing element, which can reduce the friction of the gear shaft 5, thereby extending the service life of the gear shaft 5. Secondly, the copper sleeve 12 provides a stable support for the gear shaft 5, ensuring the concentricity and straightness of the gear shaft 5 during operation, and improving the stability of the entire transmission.

[0025] Furthermore, the gear shaft 5 is provided with an anti-rolling surface 14. Since the anti-rolling surface 14 is a plane, it is constrained by the plane of the bearing seat 13, thus preventing the cylindrical gear shaft 5 from flipping.

[0026] Furthermore, the bearing 6 is a needle roller bearing. Due to its compact structure, high load-bearing capacity, high-speed operation adaptability, and strong durability, needle roller bearings can withstand large impact loads and radial loads, making them suitable for cam-driven applications.

[0027] This embodiment provides a power mechanism for a clamp longitudinal flipping 90° device. In normal use, it provides the initial power (i.e., the swinging of the rocker arm 1) to the clamp longitudinal flipping 90° device. The function of the clamp longitudinal flipping 90° device is to enable upsetting of mutually perpendicular surfaces at the same workstation. Specifically, the clamp longitudinal flipping 90° device, through the up-and-down swinging of the rocker arm 1, causes the rotating shaft 17, which is sleeved inside the rocker arm 1, to drive the rotating body 18 to flip longitudinally. The rotating body 18 contains a clamp assembly 19 (containing the product 15 to be processed). The height of the rotating body limiting plate 23 is adjusted to ensure that the clamp assembly 19 can accurately flip 90°. The clamp assembly 19 longitudinal flipping 90° device is fixed to the main mold box 22 of the cold heading machine via a base 21, which is fixed with a positioning pin 20.

[0028] The beneficial effects of this utility model are as follows: by adding a flipping cam 7 to the existing transmission shaft 8, which drives the gear shaft 5 through a bearing, and the gear shaft 5 drives the drive wheel 4 on the rocker arm 3, the rocker arm 1 is ultimately able to produce a 90° swing amplitude through the planar linkage mechanism composed of the rocker arm 3, the connecting rod 2 and the rocker arm 1. This new structure is simple and practical.
