Description

[Technical Field]

[0001] This utility model relates to the field of wire cutting machine technology, and in particular to a roller device and a wire cutting machine that are easy to replace. [Background Technology]

[0002] A wire EDM machine mainly consists of a support frame and a cutting assembly. The cutting assembly includes a mounting frame, several rollers rotatably mounted on the mounting frame, and two sets of wire take-up and unwinding systems. The cutting wire is drawn from the first set of take-up and unwinding systems and reciprocates around the rollers to form a cutting mesh. The end of the cutting wire is connected to the second set of take-up and unwinding systems. Driven by a rotary drive motor, the rollers can rotate in both directions. During this rotation, the rollers drive the cutting mesh to reciprocate and saw the material. During the cutting process, the first set of take-up and unwinding systems continuously releases new cutting wire, while the second set continuously retrieves the worn-out wire. Because the cutting wire can damage the rollers during actual use, they need to be replaced after a period of use. Therefore, there is an urgent need for a device that facilitates the replacement of the rollers. [Utility Model Content]

[0003] The technical problem to be solved by this utility model is to provide a roller device and wire cutting machine that are easy to replace, which can facilitate the replacement of rollers and improve the replacement efficiency of rollers.

[0004] This utility model is implemented as follows:

[0009] Furthermore, the first base has a first plane on the side away from the roller member, and a second plane on the side of the first base close to the roller member. The second plane is lower than the first plane, and a first vertical plane is formed between the first plane and the second plane. The bottom surface of the first roller support is in contact with the second plane, and the side of the first roller support away from the roller member is in contact with the first vertical plane.

[0010] The second base has a third plane on the side away from the roller and a fourth plane on the side close to the roller. The fourth plane is lower than the third plane. A second vertical plane is formed between the third plane and the fourth plane. The bottom surface of the second roller support is in contact with the fourth plane, and the side of the second roller support away from the roller is in contact with the second vertical plane.

[0011] Furthermore, both the first roller support and the second roller support extend outward along both sides perpendicular to the axis to form connecting portions. The connecting portion of the first roller support and the first base, as well as the connecting portion of the second roller support and the second base, are locked together by a first locking member.

[0012] Furthermore, both the first roller support and the second roller support are provided with oil seal end caps on both sides along the axial direction, and the first roller support and the second roller support are locked to the oil seal end caps by a second locking member.

[0013] Secondly, a wire cutting machine includes a frame, a support frame disposed on the frame, and the aforementioned roller assembly; two roller assemblies are disposed at the top and bottom of the support frame, and the roller assemblies are locked to the support frame by a third locking member.

[0014] Furthermore, a fifth keyway is provided axially between the top of the bearing frame and the bottom of the first and second bases of the roller assembly, and a fifth limiting key is provided in the fifth keyway.

[0015] Furthermore, the bottom of the first base and the second base of the roller assembly both extend downward on the side away from the roller to form a limiting protrusion, and the top and bottom surfaces of the support frame are both recessed downward to provide limiting steps that match the limiting protrusion.

[0044] Example 1

[0045] Please see Figures 1 to 8 As shown, this utility model discloses a roller device 100 that is easy to disassemble and replace. The roller device 100 includes a roller shaft body 1, a roller component 2 sleeved on the outside of the roller shaft body 1 (the roller component 2 and the roller shaft body 1 form a roller), a drive motor 3, a coupling 4, a first base 5, a second base 6, a first roller support 7, and a second roller support 8.

[0046] The first roller support 7 is detachably connected to the first base 5, and the second roller support 8 is detachably connected to the second base 6, so that the first roller support 7 and the first base 5, as well as the second roller support 8 and the second base 6, can be disassembled and separated during use; one end of the roller shaft body 1 is rotatably connected to the first roller support 7, and the other end of the roller shaft body 1 is rotatably connected to the second roller support 8; the output shaft 31 of the drive motor 3 is connected to one end of the roller shaft body 1 through a coupling 4, and during operation, the drive motor 3 can drive the roller shaft body 1 to rotate the roller component 2.

[0047] This invention detachably connects the first roller support 7 to the first base 5, and the second roller support 8 to the second base 6. It also rotatably connects both ends of the roller shaft body 1 to the first roller support 7 and the second roller support 8, respectively. Simultaneously, the output shaft 31 of the drive motor 3 is connected to one end of the roller shaft body 1 via a coupling 4. Therefore, in practical use, when the roller component 2 is damaged and needs replacement, it is only necessary to disassemble the first roller support 7 from the first base 5 and the second roller support 8 from the second base 6 to remove the roller shaft body 1 and the roller component 2 together from the wire cutting machine. After replacement, installation is completed simply by connecting the first roller support 7 to the first base 5 and the second roller support 8 to the second base 6. Thus, it greatly facilitates the replacement of the roller rollers, improving the replacement efficiency.

[0048] In some embodiments of this utility model, the second base 6 extends outward on the side away from the roller 2 and is provided with a motor support 65, and the drive motor 3 is mounted on the motor support 65 to realize the installation and fixation of the drive motor 3.

[0049] In some embodiments of this utility model, a first keyway 91 is provided axially (i.e., along the axis of the roller shaft body 1) between the inner wall of the coupling 4 and the outer wall of the roller shaft body 1, and a first limiting key (not shown) is provided in the first keyway 91; a second keyway 92 is provided axially (i.e., along the axis of the roller shaft body 1) between the inner wall of the coupling 4 and the output shaft 31 of the drive motor 3, and a second limiting key (not shown) is provided in the second keyway 92. This utility model assembles the coupling 4 and the roller shaft body 1, as well as the coupling 4 and the output shaft 31 of the drive motor 3, using keyways and keys. This ensures that, in practical use, the drive motor 3 can reliably drive the roller shaft body 1 to rotate in both directions after assembly, and also allows for quick separation of one end of the roller shaft body 1 from the coupling 4 when disassembling the roller roller, without having to disassemble the drive motor 3 as well.

[0050] In some embodiments of this utility model, a third keyway 93 is provided between the bottom of the first roller support 7 and the top of the first base 5 along the axial direction (i.e., along the axis of the roller shaft body 1), and a third limiting key (not shown) is disposed in the third keyway 93; a fourth keyway 94 is provided between the bottom of the second roller support 8 and the top of the second base 6 along the axial direction (i.e., along the axis of the roller shaft body 1), and a fourth limiting key (not shown) is disposed in the fourth keyway 94. By providing keyways and keys between the first roller support 7 and the first base 5, and between the second roller support 8 and the second base 6, this utility model can effectively improve the stability of the first roller support 7 and the first base 5, and between the second roller support 8 and the second base 6 after assembly, thereby ensuring the stability of the roller roller during operation.

[0051] In some embodiments of this utility model, the first base 5 has a first plane 51 formed on the side away from the roller member 2, and a second plane 52 formed on the side of the first base 5 close to the roller member 2. The second plane 52 is lower than the first plane 51, and a first vertical surface 53 is formed between the first plane 51 and the second plane 52. The bottom surface of the first roller support 7 is in contact with the second plane 52, and the side of the first roller support 7 away from the roller member 2 is in contact with the first vertical surface 53.

[0052] The second base 6 has a third plane 61 on the side away from the roller 2 and a fourth plane 62 on the side close to the roller 2. The fourth plane 62 is lower than the third plane 61. A second vertical surface 63 is formed between the third plane 61 and the fourth plane 62. The bottom surface of the second roller support 8 is in contact with the fourth plane 62, and the side of the second roller support 8 away from the roller 2 is in contact with the second vertical surface 63.

[0053] This invention designs a first base 5 with a first plane 51, a second plane 52, and a first vertical plane 53, with the second plane 52 being lower than the first plane 51. A second base 6 is designed with a third plane 61, a fourth plane 62, and a second vertical plane 63, with the fourth plane 62 being lower than the third plane 61. The bottom surface of the first roller support 7 is fitted with the second plane 52, and the side of the first roller support 7 away from the roller 2 is fitted with the first vertical plane 53. Simultaneously, the bottom surface of the second roller support 8 is fitted with the fourth plane 62, and the side of the second roller support 8 away from the roller 2 is fitted with the second vertical plane 63. This design ensures that, after assembly, the first base 5 reliably limits the position of the first roller support 7, and the second base 6 reliably limits the position of the second roller support 8, thereby improving the stability of the first roller support 7 and the second roller support 8 after assembly, and further ensuring the stability of the roller roller during operation.

[0054] In some embodiments of this utility model, the first roller support 7 and the second roller support 8 extend outward from both sides along the direction perpendicular to the axis (i.e., along the direction perpendicular to the axis of the roller shaft body 1) to form connecting portions 71 and 81. The connecting portion 71 of the first roller support 7 and the first base 5, as well as the connecting portion 81 of the second roller support 8 and the second base 6, are locked together by a first locking member (not shown). In specific implementations of this utility model, the first locking member can be a bolt or a screw, and at least two first locking members can be used to lock together the connecting portion 71 of the first roller support 7 and the first base 5, as well as the connecting portion 81 of the second roller support 8 and the second base 6, to ensure the reliability of the connection between the first roller support 7 and the first base 5, and between the second roller support 8 and the second base 6.

[0055] In some embodiments of this utility model, oil seal end caps 72 and 82 are provided on both sides along the axial direction (i.e., along the axial direction of the roller shaft body 1), and the first roller support 7 and the second roller support 8 are locked to the oil seal end caps 72 and 82 by second locking members (not shown). In specific implementations of this utility model, the second locking members can be bolts or screws, and multiple second locking members can be used to lock and connect the oil seal end cap 72 to the first roller support 7 and the oil seal end cap 82 to the second roller support 8. In the specific implementation process, in order to ensure that the roller shaft body 1 can rotate smoothly relative to the first roller support 7 and the second roller support 8, it is necessary to add lubricating oil to the first roller support 7 and the second roller support 8. Therefore, by equipping the first roller support 7 and the second roller support 8 with oil seal end caps 72 and 82 on both sides, it is possible to facilitate the assembly operation of the roller shaft body 1 and prevent the added lubricating oil from leaking out.

[0057] Please see Figures 1 to 12 As shown, this utility model discloses a wire cutting machine 200, including a frame 201, a support frame 202 mounted on the frame 201, and a roller assembly 100. The specific structure and technical effects of the roller assembly 100 are exactly the same as those in Embodiment 1. Please refer to the detailed description of Embodiment 1 for details, which will not be repeated here. Two roller assemblies 100 are provided at the top and bottom of the support frame 202, and the roller assembly 100 is locked to the support frame 202 by a third locking member (not shown) to facilitate the assembly and disassembly of the entire roller assembly 100. In specific implementation of this utility model, the third locking member can be a bolt.

[0058] In some embodiments of this utility model, a fifth keyway 95 is provided axially (i.e., along the axis of the roller shaft body 1) between the top of the support frame 202 and the bottom of the first base 5 and the second base 6 of the roller assembly 100. A fifth limiting key (not shown) is provided in the fifth keyway 95. By providing a keyway and a key between the support frame 202 and the first base 5 and the second base 6 of the roller assembly 100, this utility model can ensure the stability of the roller assembly 100 and the support frame 202 after assembly, thereby further ensuring the stability of the roller during operation.

[0059] In some embodiments of this utility model, in order to better assemble the roller device 100 with the support frame 202, the bottom of the first base 5 and the second base 6 of the roller device 100 extends downward on the side away from the roller 2 to form limiting protrusions 54 and 64. The top and bottom surfaces of the support frame 202 are both provided with limiting steps 2021 that match the limiting protrusions 54 and 64.
