Description

Technical Field

[0001] This utility model relates to the field of grinding machine fixture technology, specifically a mold grinding machine fixture. Background Technology

[0002] Molds are widely used in the machinery manufacturing industry. The manufacturing and repair of various mold inserts require specialized grinding machines. Grinding machines are machines that use abrasive wheels to grind the surface of workpieces. Most grinding machines use high-speed rotating grinding wheels for grinding. Existing mold grinding machines typically use special mold fixtures to fix the mold parts to be ground before grinding. Therefore, the mold fixture plays a very important role in the grinding quality of mold parts.

[0003] Currently, the processing angle of existing mold fixtures cannot be flexibly adjusted. Therefore, they can only process workpieces with one grinding angle, which is not suitable for workpieces with complex surfaces. Different fixtures are required to complete the processing operation, resulting in low processing efficiency and high equipment costs. Furthermore, existing mold fixtures do not have dust removal functions, making it impossible to observe the progress of grinding on the workpiece surface in a timely manner. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, such as the inability to adjust the angle and the inability to remove dust in a timely manner, this utility model proposes a mold grinding machine fixture.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a mold grinding machine fixture, including a base body, a rotation limiting mechanism is provided at the upper end of the base body, and a clamping mechanism is provided at the upper end of the rotation limiting mechanism.

[0006] The clamping mechanism includes a lower limiting slide plate, a left clamping plate integrally formed on one side of the upper part of the lower limiting slide plate, and a right upright plate integrally formed on the other side of the lower limiting slide plate. A threaded pressure rod is threadedly connected to the right upright plate, and one end of the threaded pressure rod is rotatably connected to the right clamping plate. The right clamping plate is slidably connected to the lower limiting slide plate, and a dust removal component is slidably connected to the inner side of the right clamping plate.

[0007] Preferably, the upper surface of the base body is provided with a groove, and the two sides of the groove are provided with sliding grooves. The rotation limiting mechanism is disposed in the groove and the sliding grooves. The rotation limiting mechanism includes a central support column welded and fixed to the lower end of the lower limiting slide plate. A bearing is installed in the groove, and the lower end of the central support column is fixedly inserted into the inner ring of the bearing.

[0008] Preferably, a compression spring is welded and fixed in the groove, and a pressure block is welded and fixed to the end of the compression spring. The pressure block is slidably connected in the groove, and a limiting part is integrally formed on the outside of the central support column.

[0009] Preferably, the inner side of the pressing block is provided with an arc-shaped pressing part, and the inner side of the pressing part is integrally formed with a positioning post. The side of the positioning post is integrally formed with a limiting block. The outer wall of the limiting part is correspondingly provided with a limiting groove, and the limiting groove is arranged in a circular array of twelve sets.

[0010] Preferably, the right upright plate has a threaded hole, the threaded pressure rod is threadedly connected to the right upright plate through the threaded hole, and one end of the threaded pressure rod is integrally formed with a handle, and both the threaded pressure rod and the handle have air intake pipes inside.

[0011] Preferably, a rubber pad is fitted to the outside of the throttle, and a connecting tube is integrally formed at the end of the throttle, with anti-slip textures on the outer wall of the connecting tube.

[0012] Preferably, the dust removal assembly includes a hollow plug-in plate, a slot is provided on the inner side of the right clamping plate, the plug-in plate is slidably inserted into the slot, a bearing is embedded inside the slot, one end of the threaded pressure rod is fixedly inserted into the inner ring of the bearing, and a connection port is provided on one side of the plug-in plate, the connection port being connected to the threaded pressure rod.

[0014] The advantages of this utility model are:

[0015] 1. This utility model incorporates a rotation limiting mechanism between the base body and the clamping mechanism. This mechanism allows the workpiece, which is fixed at the top, to rotate 30° to adjust its position. After the position is adjusted, the limiting block will be inserted into the limiting slot under the action of the compression spring, achieving a locking effect. The workpiece will not rotate during processing, and it can be clamped by the left and right clamping plates and adjusted to any angle, achieving the effect of angle adjustment and solving the problem of inflexible adjustment of the processing angle.

[0016] 2. This utility model incorporates a dust removal component designed on the inner side of the right clamping plate. The plug-in plate in the dust removal component is inserted into the slot and works with the right clamping plate to fix the right side of the workpiece. After the workpiece is fixed, an air supply device is connected to the connecting pipe of the throttle. The air supply device sprays high-pressure gas to remove the debris generated on the surface of the workpiece during processing, achieving the effect of dust removal. After processing is completed, the plug-in plate can be directly pulled out, and the internal debris can be poured out from the connection port at the rear of the plug-in plate, solving the problem of dust removal.

A threaded pressure rod 304 is threadedly connected to the right upright plate 303. One end of the threaded pressure rod 304 is rotatably connected to a right clamping plate 305. The right clamping plate 305 is slidably connected to the lower limiting slide plate 301, and a dust removal component 30 is slidably connected to the inner side of the right clamping plate 305.

[0028] Reference Figure 1 and Figure 2 The upper surface of the base body 1 is provided with a groove 101, and the sides of the groove 101 are provided with sliding grooves 102. The rotation limiting mechanism 2 is set in the groove 101 and the sliding grooves 102. The rotation limiting mechanism 2 includes a middle support column 201 welded and fixed to the lower end of the lower limiting slide plate 301. A bearing is installed in the groove 101, and the lower end of the middle support column 201 is fixedly inserted into the inner ring of the bearing. The middle support column 201 can be inserted into the bearing in the groove 101, so that the upper clamping mechanism 3 can adjust the angle.

[0029] Reference Figure 1 and Figure 2 A compression spring 202 is welded and fixed inside the groove 101, and a pressure block 203 is welded and fixed to the end of the compression spring 202. The pressure block 203 is slidably connected inside the groove 102, and a limiting part 204 is integrally formed on the outside of the middle support column 201. The pressure block 203 can be popped out by the compression spring 202, realizing the connection between the pressure block 203 and the limiting part 204, so that the upper clamping mechanism 3 can be locked and will not rotate when the workpiece is processed.

[0030] Reference Figure 2 and Figure 3 The inner side of the pressing block 203 is provided with an arc-shaped pressing part 205. The positioning post 206 can fit with the limiting part 204.

After the plug plate 311 is fully inserted into the right clamping plate 305, the connection port 313 will be connected to the air intake pipe 308.

[0034] Reference Figure 3 and Figure 5 The slot 312 has a plate-removing groove 314 on both sides, and the surface of the plug-in plate 311 has a dust removal hole 315. The dust removal hole 315 is inclined downward at 15° and has several sets of rectangular arrays. The plug-in plate 311 can be pulled out for cleaning through the plate-removing groove 314. The connecting port 313 at the rear of the plug-in plate 311 can pour out the internal debris. The dust removal hole 315 is located on the upper part of the plug-in plate 311 and is set to blow downward air to blow away the debris on the upper surface of the workpiece. In this way, the processing progress of the workpiece can be observed in time.

[0035] Working principle: First, insert the plug plate 311 into the slot 312. Then, place the workpiece between the left clamping plate 302 and the right clamping plate 305. Rotate the handle 307 to move the right clamping plate 305 inward to initially fix the workpiece. Then, fine-tune the position of the workpiece and further rotate the handle 307 to further fix the workpiece. Then, connect the external air supply device and the connecting pipe 310, and start the air supply device and the external processing equipment to process the workpiece. If the position needs to be adjusted after the initial processing, the air supply device and the external processing equipment can be stopped first. Then, pull out the two pressure blocks 203 to unlock. Then, rotate the clamping mechanism 3 to a suitable angle and release to lock it again. Then, the air supply device and the external processing equipment can be started to further process the workpiece. After processing, remove the workpiece and pull out the plug plate 311 to clean up the debris generated during processing.
