Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a novel mechanical processing grinder. Background Art

[0002] After the workpiece is processed, it needs to be polished. A grinder is a machine tool that uses abrasive tools to grind the surface of a workpiece. Most grinders use high-speed rotating grinding wheels for grinding, and a few use other grinding tools such as oilstones and sanding belts and free abrasives for processing. A mechanical processing grinder with publication number CN213970408U includes a support frame and a mounting plate. By installing a water tank and an ultrasonic atomizer head installed inside the water tank, fine water mist can cool the grinding wheel and the workpiece, which is not only conducive to the continuous operation of the grinding wheel, but also reduces the generation of sparks during the grinding process, improving the safety of use. However, when performing the grinding work, the staff still needs to hold the workpiece for grinding, so there is still a certain safety risk. Utility Model Content

[0026] The base 1 is a rectangular structure, which serves as the installation foundation of the grinder. A workbench 2 is installed on the right side of the top of the base 1, and a grinding mechanism 3 is installed on the left side of the workbench 2. The working end of the grinding mechanism 3 extends to the upper end of the workbench 2 to facilitate grinding of the workpiece on the workbench 2. An adjustment box 4 is installed on the left side of the grinding mechanism 3 for adjusting the entire grinder. A movable plate 5 is movably installed on the top of the workbench 2, and a connecting column 7 is fixedly installed at the top center of the movable plate 5. A placement plate 6 is installed on the top of the connecting column 7. Two connecting rods 8 are symmetrically installed on the left and right sides of the bottom of the movable plate 5. The connecting rod 8 can be divided into an upper end and a lower end. The upper end is rod-shaped and the lower end is circular plate-shaped. A first sleeve 9 is mounted on the lower ends of the two connecting rods 8, and the first sleeve 9 is fixedly connected to the workbench 2 , and the first sleeve 9 is filled with hydraulic oil, two fixed piles 10 are symmetrically installed on the left and right sides of the workbench 2, and a first cavity 10-1 is opened in the fixed pile 10, and a connecting pipe 11 is installed at the bottom of the first sleeve 9, and the other end of the connecting pipe 11 is installed on the fixed pile 10, so that the hydraulic oil in the first sleeve 9 can enter the first cavity 10-1 of the fixed pile 10 through the connecting pipe 11.

[0027] The present embodiment also has a second cavity 2-1 opened in the side walls on both sides of the workbench 2, and a first rack 16 and a second rack 17 are slidably installed on the two side walls in the second cavity 2-1, and a gear 18 is rotatably installed between the first rack 16 and the second rack 17, and the gear 18 is respectively meshed with the first rack 16 and the second rack 17, and fixed blocks 15 are symmetrically installed on the left and right sides of the movable plate 5, the fixed block 15 and the first rack 16 are fixedly connected, and the fixed block 15 is located at the top of the first rack 16, and a mounting block 19 is fixedly installed at the bottom of the second rack 17, and a baffle 20 is installed on the mounting block 19 to protect the top of the workbench 2, thereby further improving the safety of the grinder.

[0028] Furthermore, in this embodiment, a spring 21 is mounted on the upper end of the connecting rod 8, and the two ends of the spring 21 are respectively fixedly connected to the bottom of the movable plate 5 and the top of the first sleeve 9, so that the lower end of the connecting rod 8 can slide along the inner wall of the first sleeve 9, thereby better squeezing the hydraulic oil in the first sleeve 9 into the first cavity 10-1 in the fixed pile 10.

[0029] Furthermore, in this embodiment, an inclined groove 22 extending into the interior of the workbench 2 is provided on the top of the workbench 2 to facilitate the diversion of the coolant sprayed from the ultrasonic atomizing head, and a filter screen 23 is also installed inside the inclined groove 22. Impurities in the coolant can be filtered through the filter screen 23 so that the coolant can smoothly flow into the workbench 2 and be collected. The connecting column 7 passes through the filter screen 23 to ensure that the connecting column 7 can work normally.

[0030] Furthermore, in this embodiment, a hydraulically controlled one-way valve 24 is installed at the inlet and outlet of one end where the connecting pipe 11 is connected to the fixed pile 10. The hydraulically controlled one-way valve 24 can not only prevent the hydraulic oil from entering the first cavity 10-1 in the fixed pile 10 from flowing back when the clamping head 14 is working, but also open the hydraulically controlled one-way valve 24 after the workpiece grinding is completed, so that the hydraulic oil in the first cavity 10-1 can flow back into the first sleeve 9 to facilitate the next clamping and fixing of the workpiece.

[0031] Furthermore, in this embodiment, a guide groove 25 is provided on the inner wall of the workbench 2 to cooperate with the fixed block 15, so that the fixed block 15 can move up and down along the inner wall of the workbench 2. A sliding groove 26 is also provided on the front and rear side surfaces of the workbench 2 to cooperate with the mounting block 19, so that the mounting block 19 can move up and down along the front and rear side surfaces of the workbench 2.

[0033] When in use, the workpiece to be polished is placed on the surface of the placement plate 6. Under the effect of the workpiece's own weight, the placement plate 6 drives the connecting column 7 to move downward along the surface of the filter screen 23, and the connecting column 7 drives the movable plate 5 to move downward. When the movable plate 5 moves, the spring 21 is squeezed to compress it, so that the lower end of the connecting rod 8 can slide along the inner wall of the first sleeve 9, so as to squeeze the hydraulic oil in the first sleeve 9 into the first cavity 10-1 of the fixed pile 10 through the connecting pipe 11. When the hydraulic oil rises to the position of the second sleeve 12, the sleeve rod 13 in the second sleeve 12 can be pushed to move outward, and the sleeve rod 13 drives the clamping head 14 to move toward the workpiece to achieve clamping and fixing of the workpiece. It should be noted that a compression spring (not shown in the accompanying drawings) is installed at the rear end of the sleeve rod 13, so that the sleeve rod 13 is always in the second sleeve 12 without being subjected to external force;

[0034] During the movement of the movable plate 5, the movable plate 5 will also drive the fixed block 15 to move downward. When the fixed block 15 moves, it can drive the first rack 16 to move downward. The first rack 16 drives the gear 18 to rotate. The rotation of the gear 18 drives the second rack 17 to move upward. When the second rack 17 moves, it can drive the mounting block 19 to move upward. The mounting block 19 drives the baffle 20 to move upward, thereby protecting the top of the workbench 2. During grinding, the user can also observe the processing of the workpiece through the window 27, thereby improving the safety of the grinder. After grinding, the hydraulically controlled one-way valve 24 can be opened to allow the hydraulic oil in the first cavity 10-1 to flow back into the first sleeve 9, and the clamping head 14 moves to both sides to facilitate the removal of the ground workpiece.

[0035] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
