Description

Technical Field

[0001] The utility model relates to the technical field of electric spark wire cutting machine tools, in particular to a walking mechanism of an electric spark wire cutting machine tool. Background Art

[0002] The wire-cut electric discharge machine is an electrical processing device, which is mainly used to process various molds, parts, etc. with high hardness and complex shapes. Due to its high processing accuracy, it is also widely used. For example, in the patent number "CN218694670U" and the patent name "A CNC wire-cut electric discharge machine", a cutting device is provided, and the cutting device and the cutting assembly are used together. Under the action of the output end of the driver, the driver drives the threaded column to rotate, thereby driving the fixed frame to slide on the fixed frame on the limit rod, so that the fixed frame can be limited to move in the left and right directions, thereby increasing the stability during cutting. By starting the cylinder, the output end of the cylinder drives the electric spark cutting head to move up and down through two sliders in two limit slots, so that the parts placed on the lower side can be cut, so that the electric spark cutting head can efficiently cut parts of different heights and sizes, thereby improving the efficiency and quality of cutting, and facilitating personnel to operate. However, the above structure still has the following problems in actual use:

[0003] The above structure drives the fixed frame to move in the left and right directions by rotating the threaded column, and drives it to move up and down by the cylinder, so that the cutting head can cut the workpiece. However, when it is necessary to cut a workpiece with a complex structure, the cutting component not only needs to move up and down, left and right, but also needs to move forward and backward. Therefore, the cutting component cooperates between the X-axis and the Y-axis to achieve cutting of complex workpieces.

[0004] Therefore, we proposed that the walking mechanism of the wire-cut EDM machine can solve the above problems well. Utility Model Content

[0005] The purpose of the utility model is to provide a walking mechanism for an electric spark wire cutting machine tool to solve the problem raised by the above background technology that when a workpiece with a complex structure needs to be cut in the current market, the cutting component not only needs to move up and down, left and right, but also needs to move forward and backward to achieve the cutting of the complex workpiece.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a walking mechanism of an electric spark wire cutting machine tool, comprising a workbench, a vertical plate being fixed on the upper surface of the workbench;

[0007] It also includes: a transverse guide plate is arranged on the front side of the vertical plate, and the transverse guide plate is slidably connected with both sides of the vertical plate through the side plate, and a first servo motor is fixed to the right side of the transverse guide plate by bolts, and the output end of the first servo motor is fixed to the first threaded rod, and the first threaded rod is arranged inside the transverse guide plate, and the left end of the first threaded rod is connected to the transverse guide plate bearing;

[0008] The outer side surface of the first threaded rod is threadedly connected to the longitudinal guide plate, and a second threaded rod is arranged inside the longitudinal guide plate, and the outer side of the second threaded rod is threadedly connected to a connecting slider, and the lower end of the connecting slider passes through the lower surface of the longitudinal guide plate and is fixed to the cutting assembly.

[0009] Preferably, a stabilizing block is fixed to the rear side of the upper surface of the longitudinal guide plate, and a sliding connection is formed between the stabilizing block and the transverse guide plate.

[0010] Preferably, the rear end of the second threaded rod is connected to the longitudinal guide plate in a bearing, and the front end of the second threaded rod is fixed to the second servo motor, and the second servo motor is bolted to the front side of the longitudinal guide plate.

[0011] Preferably, a processing groove is opened on the upper surface of the workbench, and a scraper is arranged inside the processing groove, and the lower end surface of the scraper is in contact with the workbench.

[0012] Preferably, both ends of the scraper pass through the workbench and are threadedly connected to the third threaded rod, and two groups of the third threaded rod are provided, and the third threaded rod is arranged inside the workbench.

[0013] Preferably, the front and rear ends of the third threaded rod are connected to the workbench bearing, and a torsion spring is sleeved on the outer side of the front end of the third threaded rod. At the same time, a pull rope is wrapped around the outer side of the rear end of the third threaded rod, and the other end of the pull rope passes through the upper surface of the workbench and is fixed to the transverse guide plate.

[0014] Preferably, a connecting plate is fixed to the rear side of the transverse guide plate, and the upper surface of the connecting plate is fixed to the cylinder, while the upper end of the cylinder is fixedly connected to the vertical plate.

[0015] Compared with the prior art, the utility model has the following beneficial effects: the walking mechanism of the wire-cut electric discharge machine not only enables the cutting assembly to move forward, backward, left, right, and up and down, so that it can cut workpieces with complex structures with higher cutting accuracy and better effect, but also can automatically clean up the debris in the processing groove, saving workers' cleaning time and improving the processing effect. The specific contents are as follows:

[0016] (1) The first threaded rod drives the threaded longitudinal guide plate to move left and right, and the second threaded rod drives the threaded connecting slider to move forward and backward, so that the connecting slider drives the cutting assembly to move forward and backward, so that the cutting assembly can move forward and backward, left and right, and can cut workpieces with complex structures;

[0017] Furthermore, when the longitudinal guide plate moves left and right, it also drives the stabilizing block to move together, and through the sliding connection formed between the stabilizing block and the transverse guide plate, the longitudinal guide plate is made more stable when moving;

[0018] Furthermore, by starting the cylinder to drive the connecting plate to descend, the connecting plate drives the transverse guide plate to descend together, and then the transverse guide plate drives the longitudinal guide plate and the cutting assembly to descend together, so that the cutting assembly can be lowered to a certain height and process the workpiece in the processing groove;

[0019] (2) When the cylinder drives the transverse guide plate to reset upward, it also drives the pull rope to rise together, so that the pull rope pulls the third threaded rod to rotate together, and then drives the threaded scraper to scrape the debris in the processing groove, so that the debris is scraped together for the convenience of cleaning by the staff, which saves the cleaning time and improves the processing efficiency;

[0020] When the pull rope no longer pulls the third threaded rod to rotate, the elastic force of the torsion spring drives the third threaded rod to reverse. The reversal of the third threaded rod can not only reel in the pull rope for next use, but also drive the scraper to reset, thereby facilitating the scraper to be used again.

[0031] Embodiment 1: In order to solve the problem in the prior art that when a workpiece with a complex structure needs to be cut, the cutting assembly 13 not only needs to move up and down, left and right, but also needs to move forward and backward to achieve the cutting of the complex workpiece, the following scheme is disclosed, including a workbench 1, and a vertical plate 2 is fixed to the upper surface of the workbench 1; it also includes: a transverse guide plate 5 is arranged on the front side of the vertical plate 2, and the transverse guide plate 5 is slidably connected to both sides of the vertical plate 2 through the side plates, and at the same time, a first servo motor 6 is fixed to the right side of the transverse guide plate 5 with bolts, and the output end of the first servo motor 6 is fixed to the first threaded rod 7, and the first threaded rod 7 is arranged inside the transverse guide plate 5, and the first threaded rod 7 is arranged inside the transverse guide plate 5.

[0032] First, the connecting plate 4 is driven down by starting the cylinder 3, so that the connecting plate 4 drives the transverse guide plate 5 to descend together, and then the transverse guide plate 5 drives the longitudinal guide plate 8 and the cutting assembly 13 to descend together, so that the cutting assembly 13 can be lowered to a certain height, and the workpiece in the processing groove 18 is processed, and during the processing, the first servo motor 6 is started, so that the first servo motor 6 drives the first threaded rod 7 to rotate together, and the first threaded rod 7 rotates, so that it drives the threaded longitudinal guide plate 8 to move left and right, and the longitudinal guide plate 8 moves left and right while also driving the stabilizing block 9 to move together. The sliding connection between the stabilizing block 9 and the transverse guide plate 5 makes the longitudinal guide plate 8 more stable when moving, so that the longitudinal guide plate 8 can drive the cutting assembly 13 to move left and right, and by starting the second servo motor 10, the second servo motor 10 drives the second threaded rod 11 to rotate together, so that the second threaded rod 11 drives the threaded connecting slide block 12 to move forward and backward, and the connecting slide block 12 drives the cutting assembly 13 to move forward and backward together, so that the cutting assembly 13 can move forward, backward, left and right, so that it can cut workpieces with complex structures;

[0033] Embodiment 2: Different from Embodiment 1, this embodiment facilitates scraping off the debris in the processing groove 18. For details, refer to Figure 1 and Figure 4-Figure 5 A processing groove 18 is provided on the upper surface of the workbench 1, and a scraper 16 is provided inside the processing groove 18, and the lower end surface of the scraper 16 is in contact with the workbench 1, and both ends of the scraper 16 pass through the workbench 1 and are threadedly connected to the third threaded rod 15, and the third threaded rod 15 is provided with two groups, and the third threaded rod 15 is arranged inside the workbench 1;

[0034] At the same time, when the processing is completed, the cylinder 3 drives the transverse guide plate 5 to reset upward, and at the same time, it also drives the pull rope 14 to rise together, so that the pull rope 14 pulls the third threaded rod 15 to rotate together, and the third threaded rod 15 rotates, so that it drives the threaded scraper 16 to move forward in the processing groove 18, so that the scraper 16 can scrape the debris in the processing groove 18 while moving, so that the debris is scraped together for the convenience of cleaning by the staff, which saves the cleaning time and improves the processing efficiency;

[0035] Embodiment 3: Different from Embodiment 2, this embodiment can drive the scraper 16 to reset, thereby facilitating the scraper 16 to be used again.

At this time, the elastic force of the torsion spring 17 drives the third threaded rod 15 to reverse. By reversing the third threaded rod 15, not only can the pull rope 14 be reeled in for the next use, but the scraper 16 can also be reset, thereby facilitating the use of the scraper 16 again. The descending height of the transverse guide plate 5 is fixed, thereby ensuring that the scraper 16 can move to the rearmost side when it is reset, so that the scraper 16 can scrape off the debris next time.
