Description

Technical Field

[0001] This utility model relates to the field of wire cutting device technology, and more specifically, to a lifting mechanism and a wire cutting device. Background Technology

[0002] Wire EDM is short for CNC wire electrical discharge machining. Wire EDM uses a moving metal wire as a tool electrode, and a pulsed current is passed between the metal wire and the workpiece. The workpiece is cut by the corrosive effect of the pulsed discharge. In machining processes, especially in wire EDM, it is often necessary to first build the wire threading path, such as molybdenum wire, copper wire, or galvanized wire, before cutting. To build the wire threading path, a wire threading mechanism is usually required to guide the wire threading. When using the wire threading mechanism, the position of the mechanism needs to be adjusted to move it near the workpiece. Therefore, the wire threading mechanism usually needs to be mounted on a movable rod that can move up, down, left, and right. Currently, the movable rod for adjusting the up and down movement of the wire threading mechanism in wire EDM is usually driven by a lead screw. However, the lead screw drive mode occupies a large space and has low utilization of the lifting space. Therefore, overcoming the defects of the existing technology is an urgent problem to be solved in this technical field. Utility Model Content

[0003] This utility model provides a lifting mechanism and a wire cutting device, aiming to improve the current wire cutting adjustment and wire threading mechanism, which usually uses a lead screw to drive its up and down movement. However, the lead screw drive mode occupies a large space and has a low utilization rate of the lifting space.

[0004] To achieve the above objectives, this utility model provides a lifting mechanism, the specific technical solution of which is as follows:

[0005] A lifting mechanism includes a mounting part, on which a lifting part is provided. The lifting part includes a driving component, and the output shaft of the driving component is provided with a gear. A rack is driven to one side of the gear. The rack is fixed to a lifting rod. The rotation of the gear can drive the rack to move up and down, thereby driving the lifting rod to move up and down. A guide part is provided between the mounting part and the lifting rod, and the lifting rod moves in a straight line under the guidance of the guide part.

[0006] In one embodiment, the mounting portion includes a mounting base, and the guide portion is disposed on the mounting base.

[0007] In one embodiment, the guide includes a slider disposed on one side of the mounting base, the slider being slidably connected to a guide rail, the guide rail being fixed to the lifting rod.

[0008] In one embodiment, a slider fixing seat is provided on one side of the mounting base, and the slider is disposed on the slider fixing seat.

[0009] In one embodiment, the driving element is a motor.

[0010] This utility model also provides a wire cutting device, including the lifting mechanism as described above, and a wire cutting device body, wherein the wire cutting device body includes a U-axis and a V-axis, and the V-axis is located below the U-axis.

[0011] In one embodiment, the U-axis or V-axis is connected to the mounting base.

[0012] In one embodiment, the wire cutting equipment body is provided with a wire threading mechanism, which is fixed on the lifting rod.

[0013] In one embodiment, the threading mechanism is provided with a telescopic threading guide tube, which can move up and down along the threading mechanism.

[0014] The beneficial effects of this embodiment are:

[0015] A driving component is fixed to the slider mounting base, and a gear is fixed to the output shaft of the driving component. The gear meshes with a rack, which is fixed to the lifting rod. The driving component drives the gear to rotate, and the rotation of the gear drives the rack to move up and down, which in turn drives the lifting rod to move up and down. At the same time, a slider is fixed to the slider mounting base, and a guide rail is fixed to the lifting rod. The guide rail and the slider cooperate, allowing the slider to slide on the guide rail.

[0016] The lifting boom uses a gear and rack drive to achieve overall lifting, which has the advantages of relatively saving height space, simple structure, and more coordinated installation sheet metal appearance. In addition, the guide rail is installed separately, which has higher straightness, enabling the lifting boom to move linearly and improving processing accuracy. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0032] The technical solutions provided by the embodiments of this utility model are described below with reference to the accompanying drawings.

[0033] Please see Figure 1 , Figure 2 and Figure 3 An embodiment of this utility model provides a lifting mechanism, including a mounting part 100. The mounting part 100 includes a mounting base 110. The slider 310 can be directly fixed on the mounting base 110, or a slider fixing base 120 can be fixed on one side of the mounting base 110 by bolts. One side of the slider fixing base 120 is fixedly connected to the slider 310 by bolts.

[0034] Please see Figure 1 , Figure 3 and Figure 4 Additionally, a lifting unit 200 is provided on the mounting part 100. The lifting unit 200 includes a driving component 210. Preferably, the driving component 210 is a motor, and the motor is a servo motor, which facilitates the control of the motor's operation through a PLC program, greatly improving the degree of automation. The driving component 210 is fixed to one side of the slider fixing seat 120 by bolts. A gear 220 is provided at the end of the output shaft of the driving component 210. A rack 230 is meshed and connected to one side of the gear 220. A lifting rod 240 is fixed to one side of the rack 230. The driving component 210 drives the gear 220 to rotate, and the rotation of the gear 220 can drive the rack 230 to move up and down, and the rack 230 drives the lifting rod 240 to move up and down.

[0035] Please see Figure 2 , Figure 3 and Figure 4 It should be noted that a guide part 300 is provided between the mounting part 100 and the lifting rod 240. The lifting rod 240 moves in a straight line under the guidance of the guide part 300. Specifically, the guide part 300 includes a slider 310 and a vertical guide rail 320 slidably connected to the slider 310. The guide rail 320 is fixed to the middle of the lifting rod 240 by bolts. The gear 220 drives the rack 230 to move up and down, and the rack 230 drives the lifting rod 240 to move up and down. In turn, the lifting rod 240 drives the guide rail 320 to slide up and down in the inner groove of the slider 310. The slider 310 positions the guide rail 320 when it moves, thereby achieving the guiding and positioning of the lifting rod 240 when it moves up and down. This enables the lifting rod 240 to lift as a whole, which has the advantages of relatively saving height space, simple structure, and more coordinated installation sheet metal shape. In addition, the guide rail 320 is installed separately, which has higher straightness, enabling the lifting rod 240 to move in a straight line and improving processing accuracy.

[0036] Please see Figure 1 , Figure 6 , Figure 7 , Figure 10 and Figure 11This utility model also provides a wire cutting device, which is equipped with the aforementioned lifting mechanism. The wire cutting device also includes a wire cutting device body 400, which includes a U-axis 410 and a V-axis 420. The V-axis 420 is located below the U-axis 410. Specifically, the U-axis 410 enables the lifting mechanism to move left and right, and the V-axis 420 enables the lifting mechanism to move forward and backward (e.g., ...). Figure 7 As shown); the mounting base 110 can be mounted on the U-axis 410 or the V-axis 420, and the lifting mechanism can be mounted on the U-axis 410 or the V-axis 420. Through the cooperation of the U-axis 410 and the V-axis 420, the lifting rod 240 on the lifting mechanism can move forward, backward, left and right in the horizontal direction, thereby realizing the adjustment of the horizontal position of the lifting rod 240.

[0037] Please see Figure 2 , Figure 5 , Figure 6 , Figure 8 and Figure 9 In addition, a wire threading mechanism 430 is provided on the wire cutting equipment body 400. The wire threading mechanism 430 can be fixed to the lower end of the lifting rod 240 or to the side of the lifting rod 240 perpendicular to the guide rail 320. Thus, the lifting rod 240 can drive the wire threading mechanism 430 to move up, down, left, right, forward, and backward, thereby accurately moving the wire threading mechanism 430 to the wire threading hole position on the workpiece to be processed, which facilitates wire threading between the wire threading mechanism 430 and the workpiece. Preferably, a telescopic wire threading guide tube 431 is provided inside the wire threading mechanism 430. The telescopic wire threading guide tube 431 can move up and down inside the wire threading mechanism 430. With this setting, depending on the different processing hole positions of the workpiece, the wire threading can be performed by directly threading the wire using the wire threading mechanism or by extending the telescopic wire threading guide tube 431 downwards from the wire threading mechanism 430 until it approaches the wire threading hole entrance of the workpiece to be processed, and then the electrode wire enters the wire threading hole of the workpiece along the telescopic wire threading guide tube 431, which greatly facilitates the wire threading work.

[0038] It should be noted that the motion state and trajectory of each mechanism in this device can be automatically controlled by CNC program or PLC programming, and automatic start-stop and automatic operation can be achieved in conjunction with position switches. The above-mentioned programs and programming are common knowledge to those skilled in the art, so they will not be described in detail here.

[0039] The specific model and specifications of the drive component 210 need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0040] The power supply and principle of the drive unit 210 are clear to those skilled in the art and will not be described in detail here.
