Description

Technical Field

[0001] The utility model relates to the technical field of screw processing, in particular to a copper screw processing and positioning device. Background Art

[0002] Copper has good conductivity. Copper screws are generally used in connectors used in power transmission, especially when a long conductive path is required. When processing the screw, the two ends of the screw are usually fixed, and then a thread cutting tool or a thread milling tool is used to contact the screw, and the screw groove is cut as the screw rotates. On a CNC machining center, precise pitch and tooth profile can be controlled by programming. However, when processing some longer screws, the long screw has relatively weak resistance to deformation when subjected to local pressure. Even if the two ends are fixed, the distance between the fixed point and the contact point of the cutting head is large, which will form a long force arm. Under the action of the cutting force of the cutter head on the screw, torque and bending moment may be generated, resulting in slight elastic or plastic deformation of the screw locally. Once this cutting force continues and is large, it exceeds the yield strength of the screw material, which may cause obvious bending, affecting the processing accuracy and quality of the screw. Based on the above situation, it is necessary to design a copper screw processing positioning device to solve the above problems. Utility Model Content

[0003] The utility model provides a copper screw processing positioning device to solve the problem in the prior art that during screw processing, the cutting head generates a resistance cutting force on the middle part of the screw, causing slight elastic or plastic deformation of the screw locally, thereby affecting the screw processing quality.

DETAILED DESCRIPTION

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below with reference to specific illustrations.

[0020] Reference Figure 1-Figure 5 As shown, a copper screw processing and positioning device includes a workbench 1 and a cutting tool 4. A fixing mechanism 3 is provided on the workbench 1 for clamping the screw rod body 2 and driving the screw rod body 2 to rotate. The fixing mechanism 3 includes a fourth telescopic member 31 and a driving motor 32 connected to the fourth telescopic member 31. The movable end of the fourth telescopic member 31 and the output end of the driving motor 32 are both rotatably connected to a clamping disk 33, and the two clamping disks 33 are provided with coaxially arranged clamping grooves 34. The inner diameter of the clamping groove 34 gradually increases towards the center of the workbench 1. When in use, the two ends of the screw rod body 2 are respectively located in the two clamping grooves 34 so that the screw remains parallel to the horizontal plane of the workbench 1. The clamping disk 33 is then driven by the fourth telescopic member 31 to move in the direction of the driving motor 32. The screw rod body 2 is clamped by the two clamping disks 33, and one of the clamping disks is driven by the driving motor 32 The screw rod 2 is rotated by the first telescopic member 11 on the workbench 1, thereby driving the screw rod body 2 to rotate. When the screw rod body 2 cuts the screw groove, the height of the receiving plate 12 is adjusted by the first telescopic member 11 on the workbench 1, so that the receiving plate 12 drives the mounting seat 14 and the cutting knife 4 connected below the mounting seat 14 to adjust the height synchronously, which is suitable for cutting screw rod bodies 2 of different diameters. The cutting edge of the cutting knife 4 contacts the outer wall of the screw rod body 2. If the screw rod body 2 is long, the cutting force of the cutting knife 4 on the screw rod body 2 may cause the screw rod body 2 to generate torque and bending moment, affecting the processing of the screw. For this reason, the present invention is also provided with a support member 5, which is located on both sides of the lower end of the cutting knife 4 and can move synchronously with the movement of the cutting knife 4 to provide supporting force on both sides of the cutting force position of the screw rod body 2 to avoid bending moment of the screw. The support member 5 will be explained in detail below:

[0021] like Figure 1As shown, this is the first embodiment provided by the present invention, the support member 5 includes a receiving platform 51, and the receiving platform 51 is provided with two support seats 52 located below the screw rod body 2. Through the interference between the support seats 52 and the screw rod body 2, a supporting force is formed at the bottom of the screw rod body 2 to prevent the screw rod body 2 from forming a bending moment at the cutting force. The receiving platform 51 and the mounting seat 14 are connected by a retractable connecting plate 53, and the receiving platform 51 is slidably connected to the workbench 1, and when the second telescopic member 13 drives the mounting seat 14 to reciprocate, the receiving platform 51 is driven to slide on the workbench 1 by the retractable connecting plate 53 to achieve synchronous movement with the movement of the cutting knife 4.

[0022] like Figure 2 As shown, this is a second embodiment of the present invention, in which the support member 5 includes a receiving platform 51, and two support seats 52 are provided on the receiving platform 51, which are located below the screw rod body 2. The receiving platform 51 is connected to the mounting seat 14 through a third telescopic member 54. When supporting the screw rod body 2, the position of the receiving platform 51 is adjusted by the extension length of the third telescopic member 54, so that the support seat 52 can provide a supporting force below the screw rod body 2. The difference from the first embodiment is that the height of the support seat 52 is adjusted by the third telescopic member 54, so that it can adapt to supporting screw rod bodies 2 of different diameters. The height position of the support seat 52 is fixed, so it can only support the screw rod body 2 of a specific diameter. However, since the receiving platform 51 and the workbench 1 are slidingly connected, the force acting on the support seat 52 can be dispersed to the workbench 1, and is connected to the receiving platform 51 through the third telescopic member 54. When the support seat 52 is subjected to the resistance force of the screw rod body 2, the force will eventually be transmitted to the third telescopic member 54, generating a downward force on the third telescopic member 54, which may affect the service life of the third telescopic member 54 over time. However, it can provide support force at the lower end of the screw rod body 2 to avoid bending moment of the screw rod body 2 during cutting, and can be selected for use according to actual usage requirements.

[0023] The first telescopic member 11 , the second telescopic member 13 , the third telescopic member 54 and the fourth telescopic member 31 may all be hydraulic telescopic rods with a certain torque.

[0024] Furthermore, a rolling shaft 6 is provided inside the support seat 52. The rolling shaft 6 can be made of metal and have a solid structure to improve the service life. The rolling shaft 6 contacts the screw rod body 2, and the friction between the screw rod body 2 and the support seat 52 is reduced when the screw rod body 2 rotates. At the same time, a leakage groove can be provided at the bottom of the support seat 52 to allow cutting debris and cutting cooling oil to flow out, so as to prevent cutting debris and cutting oil from accumulating in the support seat 52.

[0025] Furthermore, after long-term use, the end of the screw rod body 2 with the screw groove cut out contacts the rolling shaft 6, which will cause damage to the surface of the rolling shaft 6. The rolling shaft 6 needs to be replaced regularly. Therefore, a connecting rod 61 is coaxially connected to the inside of the rolling shaft 6, and the two ends of the connecting rod 61 are threadedly connected to the mounting nuts 62. During installation, the connecting rod 61 is first passed through the rolling shaft 6, and then the connecting rod 61 and the rolling shaft 6 are placed in the support seat 52. By connecting the mounting nut 62 to the connecting rod 61, the connecting rod 61 is installed on the support seat 52, so that the rolling shaft 6 can be regularly disassembled and replaced.

[0026] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions are merely illustrative of the principles of the present invention. Various changes and improvements may be made to the present invention without departing from the spirit and scope of the present invention. Such changes and improvements are intended to fall within the scope of the present invention.
