Description

Technical Field

[0001] This utility model relates to the field of diamond grinding wheel dressing technology, and in particular to a diamond grinding wheel dressing device. Background Technology

[0002] EDM dressing of diamond grinding wheels is a new type of dressing technology with significant advantages such as non-contact processing, high dressing accuracy, and high efficiency. It can effectively overcome the shortcomings of traditional methods and provide a new solution for dressing diamond grinding wheels. Figure 5 This is a commonly used EDM structure for dressing diamond grinding wheels. The upper roller A and the lower roller C form a three-roller positioning system. The upper roller applies downward pressure to fix the grinding wheel rod, while the lower roller rotates actively through a fixed shaft, causing the workpiece B and the upper roller A to rotate passively. At this point, the EDM can be started by moving the graphite electrode D closer to the workpiece B.

[0003] This processing mode can only hold one product at a time, which not only results in low processing efficiency but also causes inconsistent wear on the front and back of the graphite electrode. To avoid electrode wear affecting processing accuracy, the electrode surface needs to be smoothed after each discharge, and the smoothed electrode surface is much larger than the actual usable area, which increases the cost of consumables. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies, such as low processing efficiency and inconsistent graphite electrode wear, by proposing a diamond grinding wheel dressing device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: Design a diamond grinding wheel dressing device, including electrodes, and further comprising: A dual-clamping machining assembly includes a support frame. Four sets of rotating frames are bolted to the upper end of the support frame. The four sets of rotating frames are arranged in pairs, one in front of the other and the other behind the electrode. A sliding frame is bolted to the upper end of each rotating frame. A mounting frame is welded to the upper end of each sliding frame. Lower rollers are rotatably mounted inside each of the four sets of rotating frames. An upper roller is positioned above each of the four sets of lower rollers. A sleeve is rotatably fitted onto the middle of each upper roller. A telescopic motor is installed inside the mounting frame. The telescopic end of the telescopic motor is connected to the sleeve. Workpieces are clamped between one end of the two sets of lower rollers and one end of the upper roller on the same side. Two sets of workpieces are clamped together at both ends of the four sets of lower rollers and upper rollers.

[0006] Preferably, the mounting frame has multiple sets of through holes running vertically through its interior. A sliding rod is slidably installed inside each through hole. A drive motor is provided on one side of the upper roller. The housing of the drive motor is connected to the sliding rod. The output shaft of the drive motor is connected to the upper roller via a transmission rod.

[0007] Preferably, the sleeve is connected to the sliding rod, and the sliding rod improves the stability of the sleeve's up-and-down movement.

[0008] Preferably, the gap between the two sets of lower rollers and the upper rollers is smaller than the outer diameter of the workpiece.

[0009] Preferably, two sets of support frames are symmetrically arranged along the left and right sides of the electrode.

[0010] The diamond grinding wheel dressing device proposed in this utility model has the following advantages: The dual-clamping processing assembly includes four sets of lower rollers, which are arranged in pairs and respectively located on the front and rear sides of the electrode. The four sets of lower rollers share a common upper roller to press down and rotate the workpiece, enabling the simultaneous processing of two sets of workpieces. The two sets of workpieces are located on the front and rear sides of the electrode, ensuring consistent wear on the front and rear sides of the electrode. This improves processing efficiency while achieving synchronous wear on the front and rear sides of the electrode. By using a single upper roller to press down and rotate two sets of workpieces, the downward pressure on the workpieces is made consistent, and the contact surfaces between the two workpieces and the electrodes do not interfere with each other. Ignoring the difference in electrode wear during discharge, the dimensions of the two processed workpieces will be completely consistent. Theoretically, it is possible to achieve simultaneous discharge and obtain products with consistent dimensions. Attached Figure Description

[0013] 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.

[0014] Example 1 Reference Figures 1-4 A diamond grinding wheel dressing device includes an electrode 1, and further includes: The dual-clamping processing assembly includes a support frame 2. Four sets of rotating frames 3 are bolted to the upper end of the support frame 2. The four sets of rotating frames 3 are arranged in pairs and are respectively set on the front and rear sides of the electrode 1. A sliding frame 4 is bolted to the upper end of the rotating frame 3. A mounting frame 5 is welded to the upper end of the sliding frame 4. Lower rollers 7 are rotatably installed inside each of the four sets of rotating frames 3. An upper roller 8 is set above the four sets of lower rollers 7. A sleeve 10 is rotatably sleeved in the middle of the upper roller 8. A telescopic motor 11 is installed inside the mounting frame 5. The telescopic end of the telescopic motor 11 is connected to the sleeve 10. Workpieces 9 are clamped between one end of the two sets of lower rollers 7 and the upper roller 8 on the same side. The two ends of the four sets of lower rollers 7 and the upper roller 8 cooperate to clamp two sets of workpieces 9.

[0015] Furthermore, refer to Figure 2 , Figure 3 The mounting frame 5 has multiple through holes 6 running vertically through its interior. A sliding rod 12 is slidably installed inside the through holes 6. A drive motor 13 is provided on one side of the upper roller 8. The housing of the drive motor 13 is connected to the sliding rod 12. The output shaft of the drive motor 13 is connected to the upper roller 8 via a transmission rod 14. Furthermore, refer to Figure 2 , Figure 3 The sleeve 10 is connected to the sliding rod 12, and the sliding rod 12 improves the stability of the sleeve 10 moving up and down.

[0016] Furthermore, refer to Figure 4 The gap between the two sets of lower rollers 7 and upper rollers 8 is smaller than the outer diameter of the workpiece 9.

[0017] Furthermore, refer to Figure 1 , Figure 4 Two sets of support frames 2 are symmetrically arranged on the left and right sides of electrode 1.

[0018] Working principle: Reference Figure 2 The figure shows a complete double clamping processing assembly. In the figure, the two sets of lower rollers 7 and one end of the upper roller 8 on the same side form a triangular structure, which clamps the workpiece 9. At the same time, in order to prevent the workpiece 9 from detaching during rotation, the gap between the two sets of lower rollers 7 and the upper roller 8 should be smaller than the outer diameter of the workpiece 9.

[0019] To improve processing efficiency and synchronize the wear on both sides of the electrode 1, four sets of rotating frames 3 are installed on the support frame 2. Each of the four sets of rotating frames 3 has a lower roller 7 installed inside. The four sets of lower rollers 7 are paired up and respectively located on the front and rear sides of the electrode 1. The four sets of lower rollers 7 share a common upper roller 8 to press down and rotate the workpiece 9. This enables the two sets of workpieces 9 to be processed synchronously on the front and rear sides of the electrode 1, thus synchronizing the wear rate on the front and rear sides of the electrode 1.

[0020] When the drive motor 13 is started, the output shaft of the drive motor 13 drives the transmission rod 14 to rotate along its own central axis. The transmission rod 14 drives the upper roller 8 to rotate along its own central axis. When the upper roller 8 contacts the workpiece 9, the high-speed rotating upper roller 8 will drive the workpiece 9 to rotate along its own central axis. At this time, the two sets of lower rollers 7 that play a supporting role will rotate synchronously, thereby realizing the clamping and rotation drive of the workpiece 9.

[0021] When the telescopic motor 11 is started, the telescopic end of the telescopic motor 11 drives the sleeve 10 to move longitudinally. When the telescopic motor 11 drives the sleeve 10 to move downward, the sleeve 10 will drive the upper roller 8 to descend. At this time, the upper roller 8 contacts the workpiece 9 to achieve clamping. When the telescopic motor 11 drives the sleeve 10 to move upward, the sleeve 10 will drive the upper roller 8 to rise. At this time, the upper roller 8 will disengage from the workpiece 9, and the workpiece 9 can be taken out.

[0022] To further improve processing efficiency, refer to Figure 1 The support frame 2 is symmetrically arranged in two sets along the left and right sides of the electrode 1, as shown in the reference. Figure 4 This allows for the simultaneous processing of four sets of workpieces 9 by having eight sets of lower rollers 7 and two sets of upper rollers 8.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
