Description

Technical Field

[0001] This utility model relates to a grinding device, and more particularly to a rapid grinding device for gaskets. Background Technology

[0002] Metal gaskets are components made of high-precision and high-hardness sheet materials. They are commonly used for the adjustment and measurement of precision molds or precision hardware, and are sometimes called mold gaskets or precision gap plates.

[0003] For example, a grinding device for processing metal gaskets, disclosed in Chinese Patent Publication No. CN212497006U, includes a protective cover, a transmission plate, and a base. The protective cover covers the upper part of the base. A linear guide rail is horizontally arranged in the middle of the upper surface of the base. The transmission plate is positioned above the linear guide rail and is slidably connected to it. A transmission fixing plate and a mounting plate are symmetrically arranged on both sides above the transmission plate. A transmission threaded rod is horizontally arranged in the middle of the transmission fixing plate. The external thread of the transmission threaded rod engages with the internal thread of the transmission fixing plate. An adjusting guide rail is located on the side of the transmission threaded rod near the mounting plate. This configuration of the transmission plate and clamping guide rail allows the device to simultaneously grind the sides and top surface of the metal gasket, solving the problems of narrow grinding range and low grinding efficiency in existing technologies.

[0004] The existing grinding device for processing metal gaskets has some problems. First, the metal gasket needs to be clamped with a clamping plate before processing, and clamping and disassembling takes a lot of time. Second, it can only clamp and process one metal gasket at a time, which leads to slow processing efficiency. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a rapid grinding device, including a base 1 and a workpiece 9 to be processed. A hydraulic cylinder 101 is fixedly connected to the base 1, and a first grinding disc 2 is fixedly connected to the upper end of the hydraulic cylinder 101. The workpiece 9 is placed on the first grinding disc 2. A stand 3 is fixedly connected to the base 1 near the rear edge. A limiting groove 301 is opened in the stand 3. A limiting slider 401 is slidably installed in the limiting groove 301. A support arm 4 is fixedly connected to the front of the limiting slider 401. A motor bracket 403 is fixedly connected to the support arm 4. A power motor 404 is fixedly connected to the motor bracket 403. A second grinding disc 5 is fixedly connected to the output end of the power motor 404. An anti-detachment ring 6 is connected to the bottom of the second grinding disc 5.

[0021] In this embodiment, by placing the workpiece 9 on the first grinding disc 2, activating the hydraulic cylinder 101 can move the first grinding disc 2 upwards. The upward movement of the first grinding disc 2 gradually inserts it into the anti-disengagement ring 6, at which point the anti-disengagement ring 6 will surround the first grinding disc 2. Activating the power motor 404 can drive the second grinding disc 5 to rotate. The rise of the first grinding disc 2 will cause the workpiece 9 to move closer to the second grinding disc 5, thereby utilizing the second grinding disc 5 to grind the workpiece 9. Simultaneously, since the workpiece 9 is directly placed on the first grinding disc 2, during the grinding process, the force on the workpiece 9 will be concentrated on the first grinding disc 2. The workpiece 9 moves on the first grinding disc 2, but the anti-detachment ring 6 covers the first grinding disc 2, thus preventing the workpiece 9 from being thrown off the edge. This ensures that the workpiece 9 can only move between the first grinding disc 2 and the second grinding disc 5. During the movement of the workpiece 9, the bottom of the workpiece 9 will rub against the top of the first grinding disc 2, thus grinding the top and bottom of the workpiece 9. At the same time, the workpiece 9 can be placed directly on the first grinding disc 2 without the need for cumbersome clamping, which effectively increases the grinding efficiency of the workpiece 9 and realizes the rapid grinding operation of the workpiece 9.

[0022] In order to achieve the purpose of adjusting the height of the second grinding disc 5, the device adopts the following technical solution: a threaded adjusting rod 302 is rotatably installed in the limiting slide groove 301, a knob 303 is fixedly connected to the upper end of the threaded adjusting rod 302, a scale 304 is engraved on the front of the stand 3 near one side edge, a threaded sleeve 402 is embedded in the limiting slider 401, and the threaded sleeve 402 is threadedly engaged with the threaded adjusting rod 302.

[0023] The screw adjustment rod 302 can be rotated by the knob 303. The screw adjustment rod 302 is threadedly engaged with the screw sleeve 402. The rotation of the screw adjustment rod 302 can move the support arm 4. The movement of the support arm 4 will move the power motor 404. The power motor 404 will then move the second grinding disc 5 up and down. By adjusting the gap between the second grinding disc 5 and the first grinding disc 2, and keeping the upward stroke of the hydraulic cylinder 101 constant, the height of the second grinding disc 5 can be adjusted to grind the workpiece 9 of different thicknesses. At the same time, the distance of the support arm 4 moving up and down can be easily observed by the scale 304.

[0024] In order to fix the anti-detachment ring 6 under the second grinding disc 5, the device adopts the following technical solution: a threaded connection hole 501 is opened at the lower part of the second grinding disc 5 near the periphery, a fixing foot 601 is fixedly connected around the anti-detachment ring 6, a fixing bolt 602 is provided in the fixing foot 601, the fixing bolt 602 is threadedly engaged with the threaded connection hole 501, and a washer 7 is provided between the anti-detachment ring 6 and the second grinding disc 5, and the washer 7 is sleeved on the fixing bolt 602.

[0025] By screwing the fixing bolt 602 through the fixing foot 601 into the threaded connection hole 501, and using the pad between the anti-detachment ring 6 and the second grinding disc 5, a certain gap is left between the anti-detachment ring 6 and the second grinding disc 5. This can prevent the space between the first grinding disc 2 and the second grinding disc 5 from being sealed after the anti-detachment ring 6 is put on the first grinding disc 2, and facilitate the discharge of the fumes generated during the grinding process.

[0026] The working principle and usage process of this utility model are as follows: The workpiece 9 to be processed is placed on the first grinding disc 2. The power motor 404 is started to drive the second grinding disc 5 to rotate. Subsequently, the first grinding disc 2 is started to move the workpiece 9 upwards. The first grinding disc 2 gradually inserts into the anti-detachment ring 6, so that the anti-detachment ring 6 is fitted around the first grinding disc 2. As the workpiece 9 gradually moves upwards, it comes into contact with the bottom of the second grinding disc 5. The rotating second grinding disc 5 then performs grinding operations on the top of the first grinding disc 2. During the grinding process, the workpiece 9 is subjected to force and moves on the first grinding disc 2. The anti-detachment ring 6 covers the top of the first grinding disc 2, thus preventing the workpiece 9 from being thrown off the edge. This ensures that the workpiece 9 can only move between the first grinding disc 2 and the second grinding disc 5. When the workpiece 9 moves relative to the first grinding disc 2, the bottom of the workpiece 9 is ground by the first grinding disc 2, thus simultaneously grinding both the top and bottom of the workpiece 9.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
