Description

Technical Field

[0001] This utility model relates to the technical field of positioning and guiding devices, specifically an automated wire cutting positioning and guiding device. Background Technology

[0002] Wire EDM is based on the principle of electrical discharge. During the process, a moving metal wire is used as an electrode. A pulse voltage is applied between the wire and the workpiece to create an instantaneous high-temperature heat source in the electrode gap. This causes the metal on the surface of the workpiece and the electrode wire to melt or even vaporize locally, thus achieving the cutting of the workpiece. When wire EDM plates, the plates need to be positioned and clamped.

[0003] For example, the authorized patent with announcement number CN218694667U (a positioning device for wire cutting processing) includes a base, on which top plates are fixedly installed on the left and right side walls by symmetrical brackets, and support seats are symmetrically embedded in the inner cavity of the top plates. The inner cavity of the support seats is rotatably connected to a movable shaft, and one end of a lead screw is fixedly connected to the lower end of the movable shaft. The other end of the lead screw is rotatably connected to the upper side wall of the base, and movable seats are symmetrically threaded to the outer side walls of the two lead screws. The two movable seats are symmetrically fixedly installed on the left and right side walls of the snap-fit ​​seat.

[0004] While the aforementioned existing technologies are convenient for adjustment based on the cutting position, they lack a feed guide structure, which makes automated feeding difficult during long-distance continuous wire cutting of sheet metal, resulting in reduced processing efficiency. Therefore, there is an urgent market need to develop an automated wire cutting processing positioning and guiding device to help solve the existing problems. Utility Model Content

[0005] The purpose of this invention is to provide an automated wire EDM positioning and guiding device to solve the problem mentioned in the background art, which is that it is not convenient to automatically feed the workpiece during long-distance continuous wire EDM, resulting in a decrease in processing efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automated wire EDM positioning and guiding device, comprising a table, a feed plate at the front end of the table, a linear motor below the table, a mounting plate fixedly installed at the front end of the linear motor, the mounting plate being fixedly connected to the table, an elongated slot being provided inside the table along the upper part of the linear motor, a transmission block being fixedly installed above the sliding end of the linear motor, the upper end of the transmission block penetrating the elongated slot and being fixedly connected to the feed plate, and clamping frames symmetrically arranged on both sides above the table, each clamping frame comprising a translation plate, clamping roller seats, clamping rollers, a positioning plate, and an electric cylinder, two clamping roller seats being provided and symmetrically fixedly installed at the front and rear ends of one side of the translation plate, and multiple clamping rollers being provided, the multiple clamping rollers being rotatably installed inside the clamping roller seats.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1-4 An embodiment of this utility model provides an automated wire EDM positioning and guiding device, comprising a table 1, a feed plate 2 at the front end of the table 1, a linear motor 9 at the bottom of the table 1, a mounting plate 10 fixedly installed at the front end of the linear motor 9, the mounting plate 10 being fixedly connected to the table 1, an elongated slot being provided inside the table 1 along the top of the linear motor 9, a transmission block being fixedly installed above the sliding end of the linear motor 9, the upper end of the transmission block passing through the elongated slot and being fixedly connected to the feed plate 2, and clamping frames 3 symmetrically arranged on both sides of the table 1, the clamping frame 3 comprising a translation plate 301, clamping roller seats 302, clamping rollers 303, a positioning plate 304 and an electric cylinder 305, two clamping roller seats 302 being provided and symmetrically fixedly installed at the front and rear ends of one side of the translation plate 301, and multiple clamping rollers 303 being provided, the multiple clamping rollers 303 being rotatably installed inside the clamping roller seats 302.

[0024] A linear motor 9 directly drives the feed plate 2, which, together with the long slots and transmission block structure inside the table plate 1, enables automatic feeding of the sheet metal for wire cutting and high-precision linear motion during the feeding process. This avoids the offset problems that may occur with traditional manual pushing. At the same time, the clamping frames arranged symmetrically on both sides adopt a multi-set clamping roller design, which can not only firmly clamp the sheet metal, but also greatly reduce frictional resistance through rolling contact, making long-distance continuous feeding more stable and smooth. This dual guiding mechanism not only ensures the linear stability of the sheet metal movement, but also improves the automation level and processing efficiency of continuous wire cutting.

[0025] Please see Figure 3 The positioning plate 304 is located in the middle of one side of the translation plate 301, and the electric cylinder 305 is fixedly installed in the middle of the other side of the translation plate 301. The push rod end of the electric cylinder 305 slides through the translation plate 301 and is fixedly connected to the positioning plate 304.

[0026] The position of the positioning plate 304 can be adjusted by the telescopic movement of the electric cylinder 305, thereby achieving a stable clamping of the plate. This design not only improves the versatility and flexibility of the clamping frame 3, but also ensures the stable clamping and positioning of the plate during wire cutting, thus increasing the quality of the wire cutting process.

[0027] Please see Figure 1 and Figure 3Both clamping frames 3 are equipped with transmission frames 4 on their outer sides. The transmission frame 4 includes a side plate 401, a folding plate 402, a flat plate 403, and a transmission plate 404. There are two side plates 401 and two folding plates 402. The two side plates 401 are fixedly installed at the front and rear ends of one side of the translation plate 301. The two folding plates 402 are fixedly installed below the two side plates 401 respectively. The flat plate 403 is fixedly installed between the two folding plates 402. The transmission plate 404 is fixedly installed on one side of the flat plate 403.

[0028] The transmission frame 4 enables a stable connection and transmission between the clamping frame 3 and the lead screw box 11. The side plate 401 and the folding plate 402 effectively disperse the stress during clamping and prevent deformation or displacement caused by uneven force. The flat plate 403 and the transmission plate 404 enable the transmission frame 4 to effectively transmit the driving force of the lead screw box 11 to the clamping frame 3, realizing the synchronous movement of the clamping frame 3. This design not only enhances the stability and reliability of the clamping frame, but also ensures the linear motion accuracy of the workpiece during processing and improves the quality of wire EDM.

[0029] Please see Figure 2 and Figure 4 A lead screw box 11 is fixedly installed below the platform 1. A ball screw 14 is rotatably installed inside the lead screw box 11. A drive motor for the ball screw 14 is provided on one side of the lead screw box 11. The two ends of the ball screw 14 on the outer side are threaded in opposite directions. Sliding blocks 15 are symmetrically slidably installed on the two ends of the ball screw 14 on the outer side. A connecting plate 16 is fixedly installed above the sliding blocks 15. One end of the transmission plate 404 slides into the interior of the lead screw box 11 and is fixedly connected to the connecting plate 16.

[0030] The ball screw 14 with bidirectional thread is installed in the screw box 11. Together with the sliding block 15 and the connecting plate 16, it realizes the synchronous and symmetrical movement of the clamping frames 3 on both sides, ensuring that the plate always maintains the center position during the feeding process, avoiding the skew problem caused by unilateral force, and increasing practicality.

[0031] Please see Figure 1 and Figure 3 A reinforcing plate 13 is provided on one side of the transmission frame 4. Guide rods 12 are symmetrically fixedly installed on the front and rear ends of the reinforcing plate 13 facing the transmission frame 4. One end of the guide rod 12 slides through the folding plate 402 and is fixedly connected to the platform 1.

[0032] The reinforcement plate 13 and guide rod 12 provide additional support and guidance for the transmission frame 4, improving the straightness and stability of the transmission frame 4 during transmission.

[0033] Please see Figure 1On both sides above the platform 1, upright plates 5 are symmetrically fixedly installed. A top plate 6 is fixedly installed above the upright plates 5. A pressure plate 7 is set below the top plate 6. An electric cylinder 8 is fixedly installed in the middle above the top plate 6. The push rod end of the electric cylinder 8 slides through the top plate 6 and is fixedly connected to the pressure plate 7.

[0034] By driving the pressure plate 7 to move up and down through the electric cylinder 2 8, the plate can be pressed and fixed in the vertical direction, which improves the positioning stability and accuracy of the plate during the processing and increases its practicality.

[0035] Working principle: During use, the workpiece is placed on the table 1. During the feeding process, the linear motor 9 drives the feed plate 2 to move linearly along the long slot of the table 1, realizing automatic feeding of the workpiece. The transmission frame 4, through the rigid structure composed of the side plate 401, the folding plate 402 and the flat plate 403, converts the rotational motion of the bidirectional threaded ball screw 14 in the screw box 11 into the synchronous symmetrical movement of the two clamping frames 3. The clamping frames 3, which are symmetrically arranged on both sides, form a rolling guide clamping of the workpiece through multiple sets of clamping rollers 303, which reduces frictional resistance and ensures the stability of the guide clamping. During the wire cutting process, the positioning plate 304 is moved by the electric cylinder 1 305 to stably clamp and position the workpiece. At the same time, the electric cylinder 2 8 drives the pressure plate 7 to apply a vertical clamping force to the workpiece, forming a three-dimensional positioning with the clamping frame 3, which improves the stability of the workpiece during the wire cutting process, thereby realizing the automated processing from precise positioning of the workpiece and automatic guide feeding.
