Description

Technical Field

[0001] This utility model relates to the field of cable chain support technology, specifically a machine tool cable chain support section. Background Technology

[0002] Cable drag chains, also known as cable protection drag chains, are devices used to secure cables, wires, air hoses, and hydraulic hoses to facilitate their rotation and movement. They are primarily used to protect and pull these cables, reducing external damage, and to move with the machinery.

[0003] Cable chains are typically made of plastic or metal and are structurally composed of left and right chain plates and upper and lower cover plates. Each section can be opened for easy installation and maintenance. Plastic cable chains resemble tank tracks in appearance and are composed of numerous unit links that rotate freely between each other, making them suitable for high-speed movement with low noise.

[0004] When assembling existing cable chain support sections, the two parts are mostly connected by mortise and tenon joints between the shaft and the hole. However, there is no anti-detachment reinforcement structure after the shaft and the hole are connected. Therefore, in actual use, due to the torque or external force of the cable chain support section during operation, the shaft is easy to detach from the hole, which can easily lead to the breakage of the nodes of the total cable chain, affecting the performance and the overall service life. Utility Model Content

[0005] The purpose of this utility model is to provide a machine tool cable chain support section to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a machine tool cable carrier support section, comprising a first chain plate, a limiting shaft fixedly installed on the outer side of one end of the first chain plate, the limiting shaft having a hollow internal structure, four corner support members fixedly installed inside the limiting shaft, four limiting springs fixedly installed on the outer surface of the four corner support members, a spring seat fixedly installed at the top of each limiting spring, a limiting pin fixedly installed at the top of the spring seat, the top of the limiting pin penetrating the limiting shaft, and the limiting pin slidingly connected to the limiting shaft, a shaft hole being opened on the outer wall of the other side of the first chain plate, and an inner recessed track groove being opened in the shaft hole.

[0007] Preferably, the four limiting springs are circumferentially distributed at equal intervals around the center point of the limiting shaft.

[0008] Preferably, each of the limiting posts has a ball bearing installed inside its top end.

[0009] Preferably, the limiting shaft has an external cover that can be detachably installed on its exterior by screws.

[0010] Preferably, a second chain plate is provided on one side of the first chain plate, and the first chain plate and the second chain plate have the same structural dimensions.

[0011] Preferably, a chain plate bracket is fixedly installed between the first chain plate and the second chain plate, and the first chain plate, the second chain plate, and the chain plate bracket together form a drag chain bracket section assembly.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This utility model uses the limiting and blocking effect between the protruding limiting post and the inner track groove to limit the limiting shaft and prevent it from coming out of the shaft hole. This provides good anti-loosening stability during use and effectively prevents the drag chain bracket section from breaking due to the shaft coming out. It also improves the overall stability of the drag chain bracket section assembly and extends the service life of the overall structure, resulting in a better structural performance.

[0014] Meanwhile, each limiting pin has a ball bearing installed inside its top. With this structural design, when the limiting pin is inserted into the inner track groove, the ball bearing at its top can roll and connect with the inner wall of the inner track groove. This rolling connection method can effectively improve the smoothness of the node rotation between cable chain sections, reduce rotation resistance, and has a good practical effect.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-5 The present invention provides an embodiment of a machine tool cable carrier support section, including a first chain plate 1, a limiting shaft 4 fixedly installed on the outer side of one end of the first chain plate 1, the limiting shaft 4 having a hollow internal structure design, and four corner support members 5 fixedly installed inside the limiting shaft 4. The four corner support members 5 can be used as internal support structures for the limiting shaft 4, thereby achieving the practical purpose of strengthening the structural strength of the limiting shaft 4 and having a good strengthening effect.

[0025] Please refer to the instruction manual for details. Figure 4 As shown, four limiting springs 6 are fixedly installed on the outer surface of the four corner support members 5. The four limiting springs 6 are evenly distributed circumferentially through the center point of the limiting shaft 4. A spring seat 7 is fixedly installed at the top of each limiting spring 6. A limiting pin 8 is fixedly installed at the top of the spring seat 7. The top of the limiting pin 8 passes through the limiting shaft 4 and is slidably connected to the limiting shaft 4. A shaft hole 11 is opened on the outer wall of the other side of the first chain plate 1. An inner recessed inner track groove 12 is opened in the shaft hole 11.

[0026] Based on the above structure, when it is necessary to assemble the limiting shaft 4 into the inside of the shaft hole 11, the four spring seats 7 can be manually pressed inward simultaneously. When the four spring seats 7 are pressed, they will compress the inner limiting spring 6, thereby putting the limiting spring 6 in a compressed state.

[0027] During the compression of the limiting spring 6, the limiting pin 8 at the top of the spring seat 7 can retract inward, so that the limiting pin 8 can be retracted into the sliding groove hole of the limiting shaft 4. After the limiting pin 8 retracts, the limiting shaft 4 can be inserted into the shaft hole 11 of another chain plate, so as to complete the rotational connection between the limiting shaft 4 and the other shaft hole 11.

[0028] After the limiting pivot 4 is assembled with the pivot hole 11, the spring seat 7 is released. Since the limiting spring 6 is in a compressed state, the limiting spring 6 will elastically reset when the spring seat 7 is released. Through the elastic reset action of the limiting spring 6, the upper limiting pin 8 can be pushed, causing the limiting pin 8 to be pushed out and inserted into the inner track groove 12 of the pivot hole 11. Through the limiting blocking action between the protruding limiting pin 8 and the inner track groove 12, the limiting pivot 4 can be limited to prevent it from coming off. This effectively prevents the limiting pivot 4 from coming off from the pivot hole 11, thus providing good anti-loosening stability during use. It can effectively prevent the pivot from coming off and causing the cable chain bracket section to break, effectively improving the overall stability of the cable chain bracket section assembly and extending the service life of the overall structure, resulting in a better structural performance.

[0029] To improve the contact effect between the limiting pin 8 and the inner track groove 12, enhance the smoothness of the cable chain rotation, and reduce resistance, each limiting pin 8 has a rolling ball 9 installed inside its top. With this structural design, when the limiting pin 8 is inserted into the inner track groove 12, the rolling ball 9 at its top can roll and connect with the inner wall of the inner track groove 12. This rolling connection method can effectively improve the smoothness of the node rotation between cable chain sections, reduce rotational resistance, and has a better practical effect.

[0030] In this embodiment, in order to protect the internal structure of the limiting shaft 4, an outer cover 10 is detachably installed on the outside of the limiting shaft 4 by screws. After the limiting shaft 4 is connected to the shaft hole 11, the outer cover 10 can be installed on its outside. In this way, the outer cover 10 can seal and protect the internal structure. The screw connection method can facilitate assembly and disassembly, making it convenient to use and improving the efficiency of disassembly, assembly and maintenance.

[0031] In this embodiment, in order to ensure the performance of the cable chain support section assembly, a second chain plate 2 is provided on one side of the first chain plate 1. The first chain plate 1 and the second chain plate 2 have the same structural dimensions. A chain plate bracket 3 is fixedly installed between the first chain plate 1 and the second chain plate 2. The first chain plate 1, the second chain plate 2 and the chain plate bracket 3 together form the cable chain support section assembly.

[0032] Working principle: When it is necessary to rotate and assemble two cable chain support sections, the limiting shaft 4 needs to be fitted into the shaft hole 11 of the other cable chain support section. The specific operation is as follows:

[0033] During assembly, the four spring seats 7 can be manually pressed inward simultaneously. When the four spring seats 7 are pressed, they will compress the inner limiting spring 6, thereby putting the limiting spring 6 in a compressed state.

[0034] During the compression of the limiting spring 6, the limiting pin 8 at the top of the spring seat 7 can retract inward, so that the limiting pin 8 can be retracted into the sliding groove hole of the limiting shaft 4. After the limiting pin 8 retracts, the limiting shaft 4 can be inserted into the shaft hole 11 of another chain plate, so as to complete the rotational connection between the limiting shaft 4 and the other shaft hole 11.

[0035] After the limiting pivot 4 is assembled with the pivot hole 11, the spring seat 7 is released. Since the limiting spring 6 is in a compressed state, the limiting spring 6 will elastically reset when the spring seat 7 is released. Through the elastic reset action of the limiting spring 6, the upper limiting pin 8 can be pushed, causing the limiting pin 8 to be pushed out and inserted into the inner track groove 12 of the pivot hole 11. Through the limiting blocking action between the protruding limiting pin 8 and the inner track groove 12, the limiting pivot 4 can be limited to prevent it from coming off. This effectively prevents the limiting pivot 4 from coming off from the pivot hole 11, thus providing good anti-loosening stability during use. It can effectively prevent the pivot from coming off and causing the cable chain bracket section to break, effectively improving the overall stability of the cable chain bracket section assembly and extending the service life of the overall structure, resulting in a better structural performance.

[0036] After the limiting shaft 4 is connected to the shaft hole 11, the shaft body cover 10 is installed on its outside. The shaft body cover 10 can seal and protect the internal structure. The screw connection method can facilitate assembly and disassembly, making it convenient to use and improving the efficiency of disassembly, assembly and maintenance.

[0037] When it is necessary to disassemble the cable chain support sections, the outer cover 10 of the shaft outside the limiting shaft 4 can be removed first to expose the internal structure of the limiting shaft 4. Then, the four springs 7 are manually pressed inward to make the spring seat 7 drive the limiting pin 8 to retract inward. After the limiting pin 8 has retracted into the limiting shaft 4, the limiting shaft 4 can be removed from the shaft hole 11 of the other chain plate. The structure is convenient to use and easy to inspect and maintain.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
