Description

Technical Field

[0001] This utility model relates to the technical field of benchtop grinding machines, specifically a benchtop grinding machine for parts processing. Background Technology

[0002] A bench grinder, also known as a grinding machine or polishing machine, is a tool that uses a rotating grinding wheel to grind, cut, and polish workpieces. It is widely used in the precision machining of metal, wood, and other workpieces, especially for the sharpening, grinding, and polishing of parts.

[0003] Existing benchtop grinders are typically placed on a tabletop and secured with screws through mounting holes at the four corners of their bottom. While bolts provide good stability for benchtop grinders, they also involve drilling holes in the tabletop, making the installation process cumbersome and hindering quick adjustments to the working position after installation. Therefore, we propose a benchtop grinder for parts processing. Utility Model Content

[0004] The utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] To this end, the technical solution adopted in this utility model is:

[0006] A benchtop grinding machine for machining parts includes: a grinding machine body, a mounting assembly, and a clamping assembly; the grinding machine body includes a base fixedly mounted at the bottom, and a coarse grinding wheel and a fine grinding wheel movably mounted at both ends respectively; the mounting assembly includes mounting openings on both sides of the bottom of the base, movable rods rotatably connected to the mounting openings, sliding grooves on the movable rods, pressure plates movably mounted in the sliding grooves, and clamping screws movably mounted in the movable rods; the clamping assembly includes mounting holes on the upper part of the movable rods, insert rods movably mounted in the mounting holes, and insertion holes on both sides of the lower part of the base.

[0007] Preferably, the pressure plate also has an installation cavity, in which multiple sets of movable T-blocks are arranged and installed.

[0008] Preferably, a first spring is fixedly installed on both sides of the bottom of the movable T-block, and the bottom of the first spring is fixedly connected to the pressure plate.

[0009] Preferably, a pressing hole is also provided on one side of the pressure plate, and the pressing hole is matched with the clamping screw.

[0010] Preferably, a protrusion is fixedly installed on the upper end of the insertion rod, and a second spring is movably sleeved on the outer end of the insertion rod on one side of the protrusion.

[0011] Preferably, the socket and the plug are matched.

[0012] By adopting the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0013] 1. In this utility model, when installing the bench grinder, the movable rods at opposite corners on both sides of the base can be rotated open, and the pressure plate in the movable rod can be pressed and clamped to both ends of the table by tightening the clamping screws inside the movable rod, thereby facilitating the installation and fixing of the bench grinder. The loosening of the clamping screws inside the movable rods on both sides also allows for easy changes in the usage position of the bench grinder, increasing its practicality. This is different from the problem of most bench grinders being fixed by bolts and thus inconvenient to move and adjust. At the same time, the movable T-block at the front end of the pressure plate can also retract during pressing to form a locking structure with the table, thereby increasing the stability of the bench grinder after installation.

[0014] 2. In this utility model, during the clamping process, the internal insert rods of the movable rods on both sides of the bottom of the base can be engaged with the insert holes on both sides of the base under the elastic force of the second spring, thereby clamping and fixing the movable rods in the clamping process, enhancing the stability of the movable rods during use, and ensuring the stability of the bench grinder.

[0027] The following describes, with reference to the accompanying drawings, some embodiments of the present invention, a benchtop grinding machine for machining parts.

[0028] Example 1:

[0029] Combination Figure 1-7 As shown, this utility model provides a benchtop grinding machine for parts processing, comprising: a grinding machine body 100, a mounting assembly 200, and a clamping assembly 300; the grinding machine body 100 includes a base 101 fixedly mounted at the bottom, and a coarse grinding wheel 102 and a fine grinding wheel 103 movably mounted at both ends; the mounting assembly 200 includes mounting openings 201 on both sides of the bottom of the base 101, movable rods 202 rotatably connected and mounted in the mounting openings 201, and sliding grooves 203 in the movable rods 202; the sliding grooves 203 contain... The pressure plate 204 and the movable rod 202 are both movably installed, and the clamping screws 205 are also movably installed inside them. The pressure plate 204 is also provided with an installation cavity 206. Multiple sets of movable T-blocks 207 are also movably installed in the installation cavity 206. The bottom sides of the movable T-blocks 207 are also fixedly installed with first springs 208, and the bottom of the first springs 208 are fixedly connected to the pressure plate 204. The pressure plate 204 is also provided with a pressing hole 209 on one side, and the pressing hole 209 matches the clamping screws 205.

[0030] Specifically, a benchtop grinder is a tool that uses a rotating grinding wheel to grind, cut, and polish workpieces. It is widely used for sharpening, grinding, and polishing parts. During installation, the movable rods 202 at opposite corners of the base 101 can be rotated open. By tightening the clamping screws 205 inside the movable rods 202, the pressure plates 204 in the movable rods 202 are pressed and clamped to both ends of the table, thus facilitating the installation and fixation of the benchtop grinder. Furthermore, the loosening of the clamping screws 205 inside the movable rods 202 on both sides also allows for easy... The design allows for a change in the usage position of the benchtop grinder, increasing its practicality and addressing the issue of most benchtop grinders being fixed with bolts and thus inconvenient to move and adjust. Simultaneously, the movable T-block 207 at the front end of the pressure plate 204 can retract during pressing to form a locking structure with the tabletop, thereby increasing the stability of the benchtop grinder after installation. During the pressing of the pressure plate 204, the clamping screw 205 inserts into the pressing hole 209 at the rear end of the pressure plate 204, ensuring the stability of the pressure plate 204 during pressing and thus guaranteeing the secure installation of the grinder body 100.

[0031] Example 2:

[0032] Combination Figure 4 and Figure 6 As shown in Embodiment 1, the clamping assembly 300 includes mounting holes 301 opened in the upper part of the movable rod 202, insert rods 302 movably installed in the mounting holes 301, and insertion holes 303 opened on both sides of the lower part of the base 101. A protrusion 304 is also fixedly installed on the upper end of the insert rod 302. A second spring 305 is movably sleeved on the outer end of the insert rod 302 on one side of the protrusion 304. The insertion hole 303 matches the insert rod 302.

[0033] Specifically, during clamping use, the movable rods 202 on both sides of the bottom of the base 101 can be engaged with the insertion rods 302 inside the base 101 by the elastic force of the second spring 305, thereby clamping and fixing the movable rods 202 in use, so as to enhance the stability of the movable rods 202 during use and ensure the stability of the bench grinder.

[0034] Working principle and usage process of this utility model:

[0035] When installing the grinding wheel body 100 on the tabletop, first stretch the insertion rod 302 at the rear end of the movable rod 202 in sequence, and rotate the movable rod 202 while stretching the insertion rod 302. After the movable rod 202 is rotated to be perpendicular to the base 101, the stretched insertion rod 302 can be released. Under the elastic force of the second spring 305 at its outer end, the front end of the insertion rod 302 is inserted into the insertion hole 303 in the base 101 to fix the rotated movable rod 202. After both movable rods 202 on both sides are fixed, rotate and remove the pressure plate 204 in the slide groove 203. Then, the grinding wheel body 100 can be placed horizontally on the tabletop. After installation, tighten the clamping screws 205 at the rear end of the movable rod 202 in sequence so that the clamping screws 205 move into the pressing hole 209 at the rear end of the pressure plate 204 and press the pressure plate 204. When the pressure plate 204 is pressed to the side of the table, it will press the movable T-block 207 at the front end according to the size of the table, so that the lower non-retractable part can be engaged with the table, thereby ensuring the stability of the grinding wheel body 100 after installation. When the position of the grinding wheel body 100 needs to be moved after it is fixedly installed, simply loosen the clamping screws 205 in the movable rods 202 at both ends, and the installation position of the grinding wheel body 100 can be easily adjusted at the top of the table.
