Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, specifically to a lower grinding disc mechanism for a grinding machine. Background Technology

[0002] The lower grinding disc mechanism of a grinding machine mainly consists of a lower grinding disc, a support, a bearing housing, and a drive system. During the grinding process, the drive system is activated, causing the lower grinding disc to rotate. Simultaneously, the upper grinding disc also rotates or oscillates via a corresponding drive mechanism, creating relative motion with the lower grinding disc. The workpiece is clamped between the upper and lower grinding discs, and grinding is performed through the relative motion of the discs, gradually achieving the required surface roughness and parallelism. Because the workpiece needs to be clamped between the upper and lower grinding discs, the clamping structure can hinder the removal of debris from the lower grinding disc to some extent, making it difficult to use and exhibiting certain shortcomings. Therefore, we propose a lower grinding disc mechanism for a grinding machine. Utility Model Content

[0003] The present invention aims to solve the problems existing in the prior art or related technologies.

[0004] Therefore, the technical solution adopted by this utility model is as follows: a grinding disc mechanism for a grinding machine, including a supporting rotation assembly, a cylinder, a clamping assembly, a flushing assembly, and a cleaning assembly. The supporting rotation assembly includes a support base and a drain pipe arranged at the bottom of the support base. The cylinder is arranged at the bottom of the support base. The clamping assembly includes a surrounding plate arranged at the top of the cylinder, a clamping frame arranged inside the surrounding plate, a sealing ring arranged at the bottom of the clamping frame, a slot and a mounting hole opened on the clamping frame. The flushing assembly is arranged at the top of the surrounding plate. The cleaning assembly includes a fixing plate inserted into the slot, a screw arranged at the top of the fixing plate, a nut threadedly connected to the screw, and brush bristles and a baffle arranged at the bottom of the fixing plate.

[0005] Preferably, the supporting rotation assembly further includes a support rod disposed at the bottom of the support base, a lower grinding disc body connected to the bearing of the support base, a first gear disposed at the bottom end of the lower grinding disc body, a drive motor disposed at the bottom of the support base, and a second gear fixed to the output end of the drive motor and meshing with the first gear.

[0006] Preferably, there are two cylinders, which are symmetrically arranged on the support base.

[0007] Preferably, the clamping assembly further includes a plurality of machining holes formed on the clamping frame and a plurality of fastening knobs threadedly connected to the clamping frame.

[0008] Preferably, the flushing assembly includes a vertical plate disposed at the top of the enclosure and nozzles disposed on the vertical plate.

[0009] Preferably, the bottom of both the brush bristles and the baffle are in contact with the lower grinding disc body, and the length of the baffle is longer than the radius of the lower grinding disc body.

[0010] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows: By setting up a clamping component and a cleaning component, this utility model achieves the effect of cleaning while processing without affecting the clamping of the workpiece, greatly improving efficiency. At the same time, by setting up a cylinder, it is convenient to replace the cleaning component. During use, the rotating lower grinding disc body grinds the workpiece in the clamping frame. During the grinding process, the brush bristles of the cleaning component can block smaller and lighter debris, while the baffle can block larger and heavier debris. After being blocked, due to the centrifugal force, all the debris will automatically fall onto the support base and be discharged through the drain pipe. This process avoids the problem of the clamping frame obstructing the cleaning process, which facilitates cleaning and also improves processing efficiency. At the same time, the cylinder can be controlled to drive the clamping component and the cleaning component to move upward. After moving to a suitable height, the nut can be rotated to disengage from the screw. After disengagement, the fixing plate and the clamping frame can be directly separated, and the cleaning component can be disassembled for replacement. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings. It should be noted that, unless otherwise specified, the embodiments and features of the present utility model can be combined with each other.

[0022] The following describes some embodiments of the present invention with reference to the accompanying drawings, providing a grinding disc mechanism for a grinding machine.

[0023] Example 1:

[0024] Reference Figure 1-4 This is the first embodiment of the present invention. This embodiment provides a grinding disc mechanism for a grinding machine, including a supporting rotation component 100, a cylinder 200, a clamping component 300, a rinsing component 400, and a cleaning component 500.

[0025] Specifically, the rotating support assembly 100 includes a support base 101 and a drain pipe 107 located at the bottom of the support base 101. The rotating support assembly 100 also includes a support rod 102 located at the bottom of the support base 101, a lower grinding disc body 103 connected to the bearing of the support base 101, a first gear 104 located at the bottom of the lower grinding disc body 103, a drive motor 105 located at the bottom of the support base 101, and a second gear 106 fixed to the output end of the drive motor 105 and meshing with the first gear 104. In use, the drive motor 105 can be controlled to operate. The operation of the drive motor 105 can sequentially drive the lower grinding disc body 103 through the second gear 106 and the first gear 104. The rotating lower grinding disc body 103 will grind the workpiece for processing, and the debris on the support base 101 can be discharged through the drain pipe 107 for use.

[0026] Specifically, cylinder 200 is installed at the bottom of support base 101. There are two cylinders 200, which are symmetrically arranged on support base 101. In use, the two cylinders 200 can be controlled to extend and retract synchronously. The two cylinders 200 can drive the clamping component 300, flushing component 400 and cleaning component 500 to move up and down, so as to replace the cleaning component 500.

[0027] Specifically, the clamping assembly 300 includes a surrounding plate 301 disposed at the top of the cylinder 200, a clamping frame 302 disposed inside the surrounding plate 301, a sealing ring 305 disposed at the bottom of the clamping frame 302, a slot 306 and a mounting hole 307 formed on the clamping frame 302. The clamping assembly 300 also includes several machining holes 303 formed on the clamping frame 302 and several fastening knobs 304 threadedly connected to the clamping frame 302. In use, the workpiece can be placed in the machining hole 303, and then the fastening knob 304 can be rotated until the fastening knob 304 abuts against the workpiece. At this time, the workpiece can be firmly fixed for grinding. The surrounding plate 301 has a blocking effect and facilitates the collection of debris. The sealing ring 305 can improve the sealing effect between the surrounding plate 301 and the support base 101. The slot 306 and the mounting hole 307 are used to install the cleaning assembly 500.

[0028] Specifically, the rinsing assembly 400 is installed at the top of the enclosure 301. The rinsing assembly 400 includes a vertical plate 401 installed at the top of the enclosure 301 and a nozzle 402 installed on the vertical plate 401. In use, the nozzle 402 can be connected to a water pipe. After connection, the water pipe can be rotated to open. After opening, the water is delivered to the nozzle 402 and sprayed out. The sprayed water can rinse the lower grinding disc body 103, which is convenient for cleaning debris and for grinding workpieces.

[0029] Specifically, the cleaning component 500 includes a fixing plate 501 inserted into the slot 306, a screw 504 positioned at the top of the fixing plate 501, a nut 505 threadedly connected to the screw 504, and brush bristles 502 and a baffle 503 positioned at the bottom of the fixing plate 501. The bottoms of both the brush bristles 502 and the baffle 503 abut against the lower grinding disc body 103. The length of the baffle 503 is longer than the radius of the lower grinding disc body 103. In use, the brush bristles 502 can block smaller and lighter debris, while the baffle 503 can block larger and heavier debris. Due to the centrifugal force generated by the rotation of the lower grinding disc body 103, all the debris will automatically fall onto the support base 101 and be discharged through the drain pipe 107. This process avoids the problem of the clamping frame 302 obstructing the cleaning process, thus facilitating cleaning and improving processing efficiency. At the same time, the cylinder 200 can be controlled to drive the clamping component 300 and the cleaning component 500 to move upward. After moving to a suitable height, the nut 505 can be rotated to disengage from the screw 504. After disengagement, the fixing plate 501 and the clamping frame 302 can be directly separated, and the cleaning component 500 can be disassembled for replacement.

[0030] The working principle and usage process of this utility model are as follows: During use, the rotating lower grinding disc body 103 grinds the workpiece in the clamping frame 302. During the grinding process, the brush bristles 502 of the cleaning component 500 can block smaller and lighter debris, while the baffle 503 can block larger and heavier debris. After being blocked, due to the centrifugal force, all the debris will automatically fall onto the support seat 101 and be discharged through the drain pipe 107. This process avoids the problem of the clamping frame 302 obstructing the cleaning process, which facilitates cleaning and also improves processing efficiency. At the same time, the cylinder 200 can be controlled to drive the clamping component 300 and the cleaning component 500 to move upward. After moving to a suitable height, the nut 505 can be rotated to disengage from the screw 504. After disengagement, the fixing plate 501 and the clamping frame 302 can be directly separated, and the cleaning component 500 can be disassembled for replacement.
