DETAILED DESCRIPTION
[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0023] The utility model provides Figure 1-5A high-stability grinding machine workbench is shown, a high-stability grinding machine workbench includes a workbench 1 with a cavity. In order to make people use this device more conveniently, four supporting legs are fixedly installed on the bottom of the workbench 1, and the bottoms of the four supporting legs are respectively fixed with anti-slip sleeves. The friction between the supporting legs and the ground is increased by the anti-slip sleeves, so that the device can be placed on the ground more stably. A bidirectional screw rod 9 is rotatably installed in the cavity. In order to rotatably install the bidirectional screw rod 9 in the cavity, rotation grooves are respectively opened on the inner walls on both sides of the cavity. The two ends of the bidirectional screw rod 9 extend into the two rotation grooves respectively and are respectively fixed with bearings, and the outer rings of the two bearings are respectively fixedly connected to the inner walls of the two rotation grooves, so that the bidirectional screw rod 9 is rotatably installed in the cavity. The rotation in the cavity is more stable. Two vertical plates 11 are threadedly installed on the bidirectional screw rod 9, and the tops of the two vertical plates 11 extend to the outside of the workbench 1 and are slidably connected to the workbench 1. L-shaped placement plates 12 are fixedly installed on the tops of the two vertical plates 11, and frame plates 19 are fixedly installed on the outer walls on the sides away from each other of the two L-shaped placement plates 12. Rectangular plates 14 are slidably installed on the two frame plates 19. Slots 15 are respectively opened on the outer walls on the sides away from each other of the two rectangular plates 14. Clamping rods 16 are respectively slidably installed on the two frame plates 19, and the ends of the two clamping rods 16 that are close to each other extend into the two clamping grooves 15 respectively. Clamping plates 13 are fixedly installed on the tops of the two rectangular plates 14. When the workpiece is thin, move it first. The plate 17 drives the clamping rod 16 to move out of the clamping groove 15, so that the height of the clamping plate 13 protruding from the L-shaped placement plate 12 is lower than the height of the workpiece, so that the grinding plate 8 is always not in contact with the clamping plate 13 during grinding, making it more convenient for people to grind the workpiece. Four support rods 2 are fixedly installed on the top of the workbench 1, and the tops of the four support rods 2 are respectively fixedly installed with mounting plates 3, and the bottom of the mounting plate 3 is fixedly installed with two electric push rods 4, and the output shafts of the two electric push rods 4 are fixedly installed with a cross plate 6, and the top of the cross plate 6 is fixedly installed with a rotating motor 5, and the output shaft of the rotating motor 5 passes through the cross plate 6 and is rotatably connected to the cross plate 6, and the output shaft of the rotating motor 5 is fixed with a connecting plate, and the bottom of the connecting plate is fixed with a grinding plate 8, and the bidirectional screw 9 is fixedly sleeved with a worm gear 1 0, a worm 20 is rotatably installed in the cavity, the worm 20 is meshed with the worm wheel 10, and the bottom end of the worm 20 extends to the bottom of the workbench 1, and a plurality of limit grooves 22 are provided at the bottom of the workbench 1. Since the worm wheel 10 and the worm 20 are self-locking, the worm wheel 10 cannot drive the worm 20 to rotate, and the worm 20 is limited by the limit rod 21. Therefore, when the device vibrates during operation, the bidirectional screw 9 cannot rotate, so that the two clamping plates 13 are always stably maintained at the current position to stably clamp the workpiece, thereby ensuring the accuracy of the workpiece during grinding. A rotating plate 23 is fixedly installed at the bottom end of the worm 20, and two limit rods 21 are slidably installed on the rotating plate 23. In order to reduce the friction between the limit rod 21 and the rotating plate 23,In order to reduce the wear of the limit rod 21 and increase the service life of the limit rod 21, the rotating plate 23 is provided with two through holes, in which linear bearings are fixedly installed respectively, and the two limit rods 21 respectively penetrate the two linear bearings and are slidably connected with the inner walls of the two linear bearings respectively, and the top ends of the two limit rods 21 respectively extend into the corresponding two limit grooves 22, and the bottom ends of the two limit rods 21 are fixedly installed with adjustment plates 24.
[0024] In order to ensure that one end of the limiting rod 21 is always located in the limiting groove 22 without being affected by other external forces, and thereby clamp the worm 20 so that the worm 20 can be stably maintained in the current position, a force spring 25 is fixedly installed on the top of the adjusting plate 24, and the top end of the force spring 25 is fixedly connected to the rotating plate 23.
[0025] In order to ensure that one end of the clamping rod 16 is always located in the clamping groove 15 to clamp the rectangular plate 14 without being affected by other external forces, and thereby to stably maintain the clamping plate 13 in the current position, the two clamping rods 16 are respectively fixedly installed with movable plates 17 at one end away from each other, and compression springs 18 are respectively movably sleeved on the two clamping rods 16, and one end of the two compression springs 18 is respectively fixedly connected to the corresponding movable plates 17, and the other ends of the two compression springs 18 are respectively fixedly connected to the corresponding frame plates 19. In order to increase the service life of the compression springs 18 and the force springs 25, the compression springs 18 and the force springs 25 are tin-plated springs.
[0026] The working principle of the grinding machine workbench with high stability provided by the utility model is as follows: in the initial state, the compression spring 18 and the force spring 25 are both in a stretched state. When the workpiece needs to be ground, the workpiece is first placed on the two L-shaped placement plates 12, and the adjustment plate 24 is moved downward to drive the limit rod 21 to move downward out of the limit groove 22, and the adjustment plate 24 is rotated clockwise. The rotation of the adjustment plate 24 drives the rotating plate 23 to rotate, and the rotation of the rotating plate 23 drives the worm 20 to rotate. The rotation of the worm 20 drives the worm wheel 10 to rotate and drives the bidirectional screw rod 9 to rotate. The rotation of the bidirectional screw rod 9 drives the two vertical plates 11 to move closer to each other, and the two vertical plates 11 move closer to each other to drive the two L-shaped placement plates 12 to move closer to each other. The two L-shaped placement plates 12 move closer to each other and drive the two clamping plates 13 to move closer to each other to clamp and fix the workpiece, so that the workpiece is stable. The worm 20 is clamped on the two L-shaped placement plates 12. At this moment, the adjustment plate 24 is released, and the force spring 25 will return to its original state, driving the limit rod 21 to enter the corresponding limit groove 22, clamping and limiting the worm 20, starting the electric push rod 4, and the output shaft of the electric push rod 4 extends downward to drive the cross plate 6 to move downward. The cross plate 6 moves downward and drives the grinding plate 8 to move downward to grind the workpiece. Due to the self-locking property between the worm wheel 10 and the worm 20, the worm wheel 10 cannot drive the worm 20 to rotate, and the worm 20 is limited by the limit rod 21. Therefore, when the device vibrates during operation, the bidirectional screw 9 cannot rotate, so that the two clamping plates 13 are always stably maintained in the current position to stably clamp the workpiece, so that the workpiece always remains in a stable state during grinding, thereby ensuring the accuracy of the workpiece during grinding.
[0027] When the workpiece is thin, first move the movable plate 17 to drive the clamping rod 16 to move out of the clamping slot 15, and move the clamping plate 13 downward so that the height of the clamping plate 13 protruding from the L-shaped placing plate 12 is lower than the height of the workpiece, and then the grinding plate 8 is always out of contact with the clamping plate 13 during grinding, making it more convenient for people to grind the workpiece.
[0028] Compared with the related art, the grinding machine workbench with high stability provided by the utility model has the following advantages:
[0029] Beneficial effects:
[0030] The utility model provides a grinding machine workbench with high stability. First, the workpiece is placed on the two L-shaped placing plates 12, and the adjusting plate 24 is moved downward to drive the limit rod 21 to move downward out of the limit groove 22. The adjusting plate 24 is rotated to drive the two clamping plates 13 to approach each other to clamp and fix the workpiece, and the workpiece is stably clamped on the two L-shaped placing plates 12. At this time, the adjusting plate 24 is released, and the force spring 25 is restored to its original state to drive the limit rod 21 to enter the corresponding limit groove 22 to clamp and limit the worm 20, and the output shaft of the electric push rod 4 is extended downward to drive the grinding plate 8 to move downward to grind the workpiece. Due to the self-locking property between the worm wheel 10 and the worm 20, the worm wheel 10 cannot drive the worm 20 to rotate, and the worm 20 is limited by the limit rod 21. Therefore, when the device vibrates during operation, the bidirectional screw rod 9 cannot rotate, thereby making the two clamping plates 13 always stably maintain the current position to stably clamp the workpiece, thereby ensuring the accuracy of the workpiece during grinding.
[0031] When the workpiece is thin, first move the movable plate 17 to drive the clamping rod 16 to move out of the clamping slot 15, so that the height of the clamping plate 13 protruding from the L-shaped placement plate 12 is lower than the height of the workpiece, and then during grinding, the grinding plate 8 is always out of contact with the clamping plate 13, making it more convenient for people to grind the workpiece.
[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
