Description

Technical Field

[0001] The utility model relates to the technical field of bench grinders, and specifically, to a bench grinder that is easy to maintain. Background Art

[0002] A bench grinder is a commonly used device for grinding various tools and cutters. In addition to some common requirements of grinding machines, bench grinders also have the characteristics of high rotational speed, simple structure, wide application range, and generally manual operation. Bench grinders are frequently used in tool manufacturing, usually without fixed operators, and some are poorly maintained. Injury accidents caused by not following safety operating procedures during grinding operations also account for a considerable proportion.

[0003] In the prior art, for the utility model with the authorization announcement number: CN218697044U and the name: A bench grinder that is easy to maintain, this bench grinder is fixed on the processing table through a quick-release fixing mechanism. When positioning the bench grinder, positioning clamping plates are respectively clamped at the four corners of the grinder base, and then the position of the grinder is fixed through the cooperation of an elastic buffer plate and a spring, so that on the premise of ensuring the stable installation of the grinder, it is convenient for the later disassembly and maintenance of the grinder; the elastic buffer plate plays a certain role in shock absorption for the grinder.

[0004] In the prior art, for the utility model with the authorization announcement number: CN216098108U and the name: Bench grinder that is easy to maintain, this bench grinder that is easy to maintain is provided with a fixed mounting plate that can automatically rotate on the processing table, and splicing plates are arranged at the front end of the processing table. By installing the bench grinder main body on the top of the fixed mounting plate, when repairing the bench grinder main body, the fixed mounting plate is rotated to expose the grinder base plate of the bench grinder main body, and then the left and right sides of the bench grinder main body are limited and fixed through the limit clamping plates on the splicing plates, thus facilitating the repair work.

[0005] However, when disassembling, installing and maintaining the bench grinder with the above devices, it is necessary to adjust the position of the clamping plate by screwing the screw rod, and then clamp the grinder from the side. However, only limiting it through the side clamping method cannot ensure its stability during operation. In order to further optimize the stability of the installation of the bench grinder, for this reason, a bench grinder that is easy to maintain is proposed. Summary of the Utility Model

[0006] The utility model provides a bench grinder that is easy to maintain, and solves the problem of unstable installation effect in the related technology.

[0007] The technical solution of the present utility model is as follows: An easily maintainable bench grinder, including a workbench and a bench grinder body, a clamping mechanism and a positioning mechanism are provided between the workbench and the bench grinder body. The clamping mechanism includes four positioning blocks fixedly connected to the upper surface of the workbench and limiting grooves opened on the surface of the positioning blocks. Four positioning grooves are opened on the bottom surface of the bench grinder body. A movable limiting rod is sleeved on the inner wall of each positioning groove. A connecting block is fixedly connected to the outer surface of each limiting rod. A telescopic spring is fixedly connected to the outer surface of each connecting block. The positioning mechanism includes lead screws threadedly connected to both sides of the workbench.

[0008] Further, the four telescopic springs are respectively sleeved on the outside of the four limiting rods. One ends of the four telescopic springs are respectively fixedly connected to both sides of the outer surface of the bench grinder body. By defining the positional relationship of the telescopic springs, it is convenient to limit the position of the limiting rods and facilitate the disassembly and assembly of the bench grinder body.

[0009] Further, the output end of each limiting rod is rounded, and the top end of each positioning block is rounded. The dimension value of the limiting rod is the same as the dimension value of the limiting groove. By rounding the surfaces of the positioning block and the limiting rod, a faster installation work can be achieved.

[0010] Further, a handle is fixedly connected to the outer surface of each connecting block. The workbench and the bench grinder body are clamped through the clamping mechanism. By setting the handle, the contact area of the connecting block can be increased, which is convenient for pulling the connecting block, thus facilitating the disassembly of the bench grinder body and being beneficial to the maintenance work of the bench grinder body.

[0011] Further, a rotatable pressing block is installed at the top end of each lead screw, and a positioning post is fixedly connected to the bottom surface of each pressing block. By setting the pressing block and the positioning post, the positioning of the bench grinder body can be further carried out, improving the stability of the bench grinder body during installation.

[0012] Further, two symmetrically arranged positioning holes are opened on the surface of the bench grinder body. The diameter value of the positioning hole is the same as the diameter value of the positioning post. By setting the positioning hole, it is convenient to insert the positioning post into the positioning hole to facilitate the positioning of the bench grinder body.

[0013] Further, a knob is fixedly connected to the bottom end of each lead screw, and an anti-slip layer is coated on the outer surface of each knob. By setting the knob, it is convenient to rotate the lead screw, thus facilitating the adjustment of the height of the pressing block.

[0014] Furthermore, two storage boxes are fixedly connected to the bottom surface of the workbench, and a reinforcement base is fixedly connected to the bottom end of the workbench. By setting up the storage boxes, it is convenient to store other tools for processing. By setting up the reinforcement base, the stability of the workbench can be improved.

[0015] The working principle and beneficial effects of the present utility model are as follows:

[0016] 1. In the present utility model, through the mutual cooperation between the clamping mechanism and the positioning mechanism, the bench grinder body can be more quickly clamped on the workbench. At the same time, through the positioning mechanism to assist in positioning the bench grinder body, the stability during the installation of the bench grinder body can be effectively improved, which is convenient for the bench grinder body to grind various tools. At the same time, for the disassembly work of the bench grinder body, the screw rod can be rotated to release the positioning of the bench grinder body by the pressing block, and then the connecting block is pulled outwards to move the limiting rod out of the limiting groove, and the pressing block releases the positioning of the bench grinder body, and then the bench grinder body can be disassembled for maintenance work, which is more practical.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0024] Next, in combination with the embodiments of the present utility model, the technical solutions in the embodiments of the present utility model will be clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present utility model.

[0025] Embodiment 1

[0026] As Figures 1 to 5 shown, this embodiment proposes an easily maintainable bench grinder, which includes a workbench 1 and a bench grinder body 2. A clamping mechanism 3 and a positioning mechanism 4 are provided between the workbench 1 and the bench grinder body 2, and the workbench 1 and the bench grinder body 2 are clamped through the clamping mechanism 3.

[0027] The clamping mechanism 3 includes four positioning blocks 301 fixedly connected to the upper surface of the workbench 1 and limiting grooves 302 opened on the surfaces of the positioning blocks 301. By providing the positioning blocks 301, it is convenient to position and install the bench grinder body 2 on the upper surface of the workbench 1.

[0028] Four positioning grooves 303 are opened on the bottom surface of the bench grinder body 2. A movable limiting rod 304 is sleeved on the inner wall of each positioning groove 303. A connecting block 305 is fixedly connected to the outer surface of each limiting rod 304, and a telescopic spring 306 is fixedly connected to the outer surface of each connecting block 305.

[0029] The four telescopic springs 306 are respectively sleeved outside the four limiting rods 304. One ends of the four telescopic springs 306 are respectively fixedly connected to both sides of the outer surface of the bench grinder body 2. By limiting the positional relationship of the telescopic springs 306, it is convenient to limit the position of the limiting rods 304 and facilitate the disassembly and assembly work of the bench grinder body 2.

[0030] When the telescopic spring 306 deforms, it will generate an elastic force. Through the elastic force generated by the telescopic spring 306, it is convenient to reset the limiting rod 304.

[0031] The output ends of each limiting rod 304 are all rounded, and the tops of each positioning block 301 are all rounded. The dimensional values of the limiting rod 304 are the same as those of the limiting groove 302. By rounding the surfaces of the positioning block 301 and the limiting rod 304, faster installation work can be achieved.

[0032] The quick disassembly and assembly of the bench grinder body 2 can be achieved through the provided clamping mechanism 3. When the bench grinder body 2 needs to be disassembled, the four limit rods 304 can be removed from the corresponding limit slots 302 respectively by pulling the four handles 307 outwards to release the limit, and then the bench grinder body 2 can be disassembled from the workbench 1 for maintenance work.

[0033] For the installation of the bench grinder body 2, the four positioning slots 303 on the bottom surface of the bench grinder body 2 can be inserted corresponding to the four positioning blocks 301 on the upper surface of the workbench 1. During the insertion process, since the surfaces of the positioning blocks 301 and the limit rods 304 are both rounded, when inserting, the positioning blocks 301 will extrude the corresponding limit rods 304 outwards, and at the same time, the limit rods 304 will make the telescopic springs 306 in a stretched state. When the bottom surface of the bench grinder body 2 contacts the upper surface of the workbench 1, the limit rods 304 will be reset by the elastic force generated by the deformation of the telescopic springs 306, realizing that the limit rods 304 are snapped into the corresponding limit slots 302, and completing the work of clamping the bench grinder body 2 on the upper surface of the workbench 1. Compared with the mechanism in the comparative document, the installation method of the present application is more convenient.

[0034] A handle 307 is fixedly connected to the outer surface of each connecting block 305. By setting the handle 307, the contact area of the connecting block 305 can be increased, which is convenient for pulling the connecting block 305, thus facilitating the disassembly work of the bench grinder body 2 and being beneficial to the maintenance work of the bench grinder body 2.

[0035] Embodiment 2

[0036] As Figures 1 to 5 shown, based on the same concept as the above Embodiment 1, this embodiment also proposes that the positioning mechanism 4 includes lead screws 401 threadedly connected to both sides of the workbench 1. A rotatable pressing block 402 is installed at the top of each lead screw 401, and a positioning column 403 is fixedly connected to the bottom surface of each pressing block 402. By setting the pressing blocks 402 and the positioning columns 403, the positioning work of the bench grinder body 2 can be further carried out, improving the stability of the bench grinder body 2 during installation.

[0037] When the lead screw 401 rotates, it will drive the pressing block 402 and the positioning column 403 to move. The rotation of the lead screw 401 can change the height of the pressing block 402 and the positioning column 403, thus facilitating the further positioning work of the bench grinder body 2, improving the stability of the bench grinder body 2 during installation, and facilitating the grinding work through the bench grinder body 2.

[0038] The surface of the bench grinder body 2 is provided with two symmetrically arranged positioning holes 404. The diameter value of the positioning hole 404 is the same as that of the positioning column 403. By setting the positioning hole 404, it is convenient to insert the positioning column 403 into the positioning hole 404, which is convenient for positioning the bench grinder body 2.

[0039] A knob 405 is fixedly connected to the bottom end of each lead screw 401, and an anti-slip layer is coated on the outer surface of each knob 405. By setting the knob 405, it is convenient to rotate the lead screw 401.

[0040] As Figure 3 shown, this is the state when the workbench 1 and the bench grinder body 2 are not combined. As Figure 1 shown, at this time, the workbench 1 and the bench grinder body 2 are clamped together by the clamping mechanism 3. In order to further improve the installation stability of the bench grinder body 2, the pressing block 402 can be toggled to make the positioning column 403 directly above the positioning hole 404, and then the lead screw 401 is rotated to make the pressing block 402 move downward. During the rotation of the lead screw 401, the pressing block 402 needs to be held by hand to make the position of the positioning column 403 correspond to that of the positioning hole 404. Then, through the movement of the pressing block 402, the positioning column 403 can be inserted into the positioning hole 404, and at the same time, the pressing block 402 will press down the bench grinder body 2, thereby improving the installation stability of the bench grinder body 2.

[0041] Two storage boxes 5 are fixedly connected to the bottom surface of the workbench 1, and a reinforcing seat 6 is fixedly connected to the bottom end of the workbench 1. By setting the storage box 5, it is convenient to store other tools for processing. By setting the reinforcing seat 6, the stability of the workbench 1 can be improved.

[0042] Working principle: When maintenance of the bench grinder body 2 is required, the bench grinder body 2 can be disassembled from the workbench 1 for more comprehensive maintenance work. At this time, the knobs 405 on both sides can be rotated first to make the two pressing blocks 402 move upward until the positioning column 403 completely moves out of the positioning hole 404, and then the pressing block 402 is rotated to select the positioning column 403 to be as Figure 3In the shown state, then pull the four connecting blocks 305 outwards so that the four limiting rods 304 are respectively removed from the corresponding limiting grooves 302, and the bench grinder body 2 can be removed from the workbench 1 for maintenance work. After completing the maintenance work on the bench grinder body 2, the four positioning grooves 303 on the bottom surface of the bench grinder body 2 can be respectively inserted corresponding to the four positioning blocks 301 on the upper surface of the workbench 1. During the insertion process, the top end of the positioning block 301 will squeeze one end of the limiting rod 304, causing the limiting rod 304 to move outwards, so that the corresponding telescopic spring 306 is stretched to generate elastic force. When the bottom surface of the bench grinder body 2 contacts the upper surface of the workbench 1 after insertion, the limiting rod 304 will bounce into the corresponding limiting groove 302 by means of the elastic force of the telescopic spring 306, achieving the effect of quickly clamping the bench grinder body 2 on the workbench 1. Then rotate the pressing block 402 to adjust the positioning post 403 to the state as shown in Figure 1 . Then rotate the knob 405 to drive the pressing block 402 to drive the positioning post 403 to move downwards. During the rotation, it is necessary to hold the pressing block 402 by hand, so as to ensure that the positioning post 403 is inserted into the positioning hole 404, realizing the further positioning work of the bench grinder body 2. Compared with the comparative document mentioned in the background art, this device can have a more stable installation effect and is convenient for grinding work through the bench grinder body 2.

[0043] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
