Description

Technical Field

[0001] The utility model relates to the technical field of machine tools, in particular to an X-axis wiring structure of a machine tool. Background Art

[0002] Currently, explosion-proof pipes are commonly used as a protection method for X-axis wiring of machine tools. However, this design has some defects and shortcomings.

[0003] First, the fully enclosed nature of the explosion-proof tube makes it difficult to inspect and maintain the cables inside. Whenever cables need to be inspected, workers often have to dismantle the tube, a tedious process that significantly increases the time and cost of maintenance.

[0004] Secondly, the use of explosion-proof pipes limits the heat dissipation efficiency of the cables to a certain extent. Especially when the machine tool is operating for a long time or generating a large amount of heat energy, if the cable cannot effectively dissipate heat, it may cause unstable operation of the machine tool and even shorten the overall service life of the machine tool.

[0005] In addition, during the operation of the machine tool, the explosion-proof pipe will often interfere with other parts of the machine tool due to its irregular running trajectory. This not only increases the risk of pipeline damage, but may also have an adverse impact on the overall performance and safety of the machine tool.

[0006] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of the present disclosure, and therefore may include information that does not constitute prior art known to ordinary technicians in the field.

[0021] (3) Beneficial effects

[0022] Compared with the prior art, the X-axis routing structure of the machine tool provided by the present invention has the following beneficial effects:

[0023] Enhanced cable routing stability and reduced interference risk: During operation, cables are routed in an orderly fashion through the cable chain's wiring holes and protected by the cable chain. As the machine tool moves along the X-axis, the chain is dragged along by the connector. The chain's strip-shaped design and the pinned connections between the links, combined with the limiting action of the track plate's track grooves, ensure smooth and regular chain movement within the grooves, significantly reducing the risk of interference with other components.

[0024] Improve the convenience of line maintenance: Removable pins are used to connect the chain links and the chain links to the connectors. This design allows the chain links and connectors to be quickly separated by removing the pins when a line fault occurs, greatly simplifying the maintenance process and improving maintenance efficiency.

[0025] Optimized heat dissipation performance: Heat dissipation holes are specially designed on the chain links, and corresponding through holes are also provided on the track plate. This design effectively promotes the heat dissipation of the lines in the drag chain and improves the overall heat dissipation performance.

[0026] When the machine tool is in operation, the wiring is routed through the wiring holes of the drag chain and protected by the drag chain. The machine tool body moves along the X-axis direction and is dragged by a connector to move the chain. Because the chain is strip-shaped and the links are connected by pins, the chain links located in the track groove can move along the track groove of the track plate, thereby improving the regularity of its movement trajectory and reducing the risk of interference with other components. At the same time, the chain links and the link and the connector are detachably connected by pins. When a line fault occurs, the link and the connector can be separated by removing the pin, improving the convenience of line maintenance. Last but not least, the chain links are provided with heat dissipation holes, and the track plate is provided with through holes to make way for the heat dissipation holes, thereby improving the heat dissipation of the line in the drag chain. It can be seen that the X-axis wiring structure of the machine tool of the present invention can improve the heat dissipation of the wiring structure, the stability of movement, and the convenience of disassembly and assembly.

[0038] The existing X-axis routing structure of machine tools is insufficient in terms of heat dissipation, movement stability and ease of assembly and disassembly.

[0039] In order to solve the above technical problems, this embodiment provides a machine tool X-axis routing structure, please refer to Figures 1 to 5 As shown, Figure 1 is a three-dimensional diagram of the machine tool in the embodiment, Figure 2 is a schematic diagram of a machine tool in the embodiment, Figure 3 This is an exploded view of the drag chain and connection components in the embodiment. Figure 4 This is the main view of the drag chain and connection components in the embodiment. Figure 5 for Figure 4 A sectional perspective view of section A.

[0040] A machine tool X-axis routing structure of this embodiment includes: a drag chain 1, a track plate 2 and a connecting component 3.

[0041] The drag chain 1 includes several links 11 and two connectors 12. Unlike existing drag chains 1, the links 11 are detachably connected sequentially via pins 13 to form a strip-shaped chain. The pins 13 are parallel to each other, and the two connectors 12 are detachably connected to the ends of the chain via pins 13. Through holes are provided within the links 11 and connectors 12, and these through holes are connected sequentially to form wiring holes 101 for routing circuits. Each link 11 is provided with heat dissipation holes 102. It is understood that the number of links 11 can be increased or decreased depending on the desired length of the drag chain 1.

[0042] The track plate 2 is fixed relative to the frame 4 of the machine tool and is provided with a track groove 21 extending along the X-axis. A clearance through hole 22 is provided on the track groove 21 .

[0043] Among them, the two connecting heads 12 are respectively connected to the machine tool body 5 and the track plate 2 through the connecting component 3. The machine tool body 5 has the freedom to move along the X-axis for processing parts; at least part of the chain links 11 are movably arranged in the track groove 21, and the heat dissipation holes 102 of the chain links 11 in the track groove 21 are connected to the clearance holes 22.

[0044] When the machine tool of the above technical solution is working, the line is routed through the wiring hole 101 of the drag chain 1 and is protected by the drag chain 1. The machine tool body 5 moves along the X-axis direction and is dragged to move by a connector 12. Since the chain is in a strip shape and the chain links 11 are connected by a pin 13, the chain link 11 located in the track groove 21 can move along the track groove 21 of the track plate 2, thereby improving the regularity of its movement trajectory and reducing the risk of interference with other components; at the same time, the chain links 11 and the chain links 11 and the connector 12 are detachably connected by the pin 13, so that when a line fails, the chain link 11 and the connector 12 can be separated by removing the pin 13, thereby improving the convenience of line maintenance; last but not least, a heat dissipation hole 102 is provided on the chain link 11, and a makeshift through-hole 22 is provided on the track plate 2 to make way for the heat dissipation hole 102, so that the heat dissipation of the line in the drag chain 1 is improved. It can be seen that the X-axis wiring structure of the machine tool of the above technical solution can improve the heat dissipation, movement stability and convenience of disassembly and assembly of the wiring structure, which is beneficial to improving the stability and life of the machine tool.

[0045] In one embodiment of the connection between the connector 12 and the machine tool body 5 and the track plate 2 via the connection assembly 3, see Figure 3 and Figure 4As shown, the connecting assembly 3 includes a connecting seat 31, a pin 32 and a spring 33; the connecting seat 31 is connected to the track plate 2 or the machine tool body 5, such as by a bolt fixed connection, and a slot 301 is provided inside the connecting seat 31, and one end of the slot 301 is provided with a notch for the connector 12 to be inserted along the X-axis direction, and the other end is provided with a slot wall 302 for limiting the insertion depth of the connector 12, and the inner side of the slot 301 is also provided with a limiting wall 303 for limiting the movement of the connector 12 along the Y-axis and Z-axis directions. The Y-axis direction, the Z-axis direction and the X-axis direction are perpendicular to each other, and the connecting seat 31 is provided with a pin hole 304, and the two ends of the pin hole 304 are respectively connected to the slot 301 and the outside of the connecting seat 31; the pin 32 is movably provided in the pin hole 304, and has There are two states: inserting into the slot 301 and withdrawing from the slot 301. A guiding slope 305 is provided at one end of the pin 32 facing the slot 301, and the other end is exposed at the connecting seat 31; a spring 33 is provided between the connecting seat 31 and the pin 32, and is configured to drive the pin 32 to extend into the slot 301 when the pin 32 withdraws from the slot 301; wherein, the connector 12 is provided with a positioning hole 100; in the initial state, the spring 33 drives the pin 32 to extend into the slot 301; when the connector 12 is inserted into the slot 301, the guiding slope 305 is pushed to withdraw the pin 32 from the slot 301; when the positioning hole 100 is relative to the pin hole 304, the spring 33 drives the pin 32 to extend into the slot 301 and the positioning hole 100. With such arrangement, when the connector 12 is connected to the track plate 2 or the machine tool body 5, it only needs to be inserted into the slot 301 from the opening, and the pin 32 can be automatically inserted into the positioning hole 100 to position the connector 12. Combined with the limiting effect of the slot wall 302 and the limiting wall 303 on the connector 12, the connector 12 is completely fixed on the connecting seat 31. When disassembling, it is only necessary to pull the pin 32 out of the positioning hole 100, and the connector 12 can be pulled out from the connecting seat 31. It can be seen that the connection component 3 and the connector 12 of this embodiment have the advantages of easy disassembly and assembly and firm connection.

[0046] It can be understood that the connection seat 31 has a through hole for the line to pass through so as to connect to the machine tool body 5 .

[0047] Among them, see Figure 3 and Figure 4 As shown, the spring 33 can be a tension spring, and a head is provided at the end of the pin 32 facing away from the slot 301. The tension spring is sleeved around the outer periphery of the pin 32, and one end is connected to the connecting seat 31, and the other end is connected to the head. The tension spring drives the pin 32 to move toward the slot 301 by stretching elastic deformation.

[0048] Exemplarily, both ends of the tension spring are connected to the connecting seat 31 and the head by bonding or welding.

[0049] It is understandable that the spring 33 may also be a compression spring, and the drive pin 13 moves by being compressed.

[0050] In order to further improve the firmness of the connection between the connector 12 and the connector base 31, the connector 12 is provided with at least two positioning holes 100, and each positioning hole 100 is staggered with each other in the Y-axis direction. The connecting component 3 includes pins 32 with the same number and relative positions as the positioning holes 100, so that when the connector 12 is inserted into the slot 301, each positioning hole 100 and each pin hole 304 are positioned relative to each other at the same time, and each pin 32 is respectively inserted into each positioning hole 100, that is, the connector 12 and the connector base 31 are fixed together by multiple positioning holes 100 and pins 32 at the same time, thereby improving the firmness of the connection between them.

[0051] In order to facilitate the adjustment of the depth of the connector 12 inserted into the connector seat 31, refer to Figure 4 and Figure 5 As shown, the connector 12 is provided with at least two positioning holes 100, and each positioning hole 100 is arranged in sequence in the X-axis direction. The connecting component 3 includes a pin 32. It can be understood that the connector 12 cooperates with the pin 32 through different positioning holes 100 to adjust the depth of its cooperation with the connecting seat 31.

[0052] In order to make the connector 12 push the guide slope 305, see Figure 4 As shown, the action of the latch 32 withdrawing from the slot 301 is smoother. In the initial state, the guide slope 305 is partially located in the pin hole 304, and the resistance of the connector 12 to push the latch 32 can be adjusted by adjusting the slope of the guide slope 305.

[0053] In order to facilitate the insertion of the connector 31 into the slot 301, see Figure 3 As shown, illustratively, the limiting wall 303 is provided with a guide surface 306 extending toward the notch, so that the diameter of the notch gradually decreases along the direction in which the connector 12 is inserted into the slot 301 .

[0054] Exemplarily, one end of the pin 13 is limited to one side of the chain link 11 by an integrally formed large end, and the other end is threadedly connected to a nut and limited to the other side of the chain link by the nut.

[0055] Exemplarily, the above-mentioned machine tool is a horizontal machine tool.

[0056] Although the 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 variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
