Description

Technical Field

[0001] This utility model relates to the field of grinding machine technology, and in particular to a lifting structure for a surface grinder with good stability. Background Technology

[0002] A surface grinder is a type of grinding machine that uses a rotating grinding wheel to grind workpieces to achieve the required flatness. With the development of society, surface grinders have been put into use in large quantities. Currently, most surface grinders are equipped with a lifting structure to process workpieces of different specifications.

[0003] Existing technologies, such as the utility model with publication number CN210588759U, disclose a lifting mechanism for a surface grinder. The upper surface of the bed has a column, guide rods on both sides of the column, a support plate at the rear end of the column, and a lead screw at the front end. The top of the column, the guide rods, and the lead screw are all connected to the lower surface of the support plate. Reinforcing plates are provided at the bottom of the column and the bottom of the support plate. A lifting drive motor is located on the upper surface of the support plate and connected to the lead screw. The lifting seat is connected to the column, guide rods, and lead screw. The grinding wheel is housed inside a grinding wheel cover, and a grinding wheel drive motor is connected to the grinding wheel. This utility model has a reasonable structure. The inverted "L"-shaped support plate on the upper surface of the bed not only guides but also supports and stabilizes the column. The reinforcing plates at the bottom of the support plate and the bottom of the column greatly improve stability, making the lifting seat more stable during operation.

[0004] The inventors discovered in their daily work that most surface grinders currently use lead screws to drive the grinding equipment for surface grinding operations. However, the platform on which the grinding equipment is installed is only connected to the lead screw, which easily leads to uneven force distribution. When adjusting the equipment, the grinding equipment is prone to vibration, resulting in defective products and increasing the economic losses of users. Therefore, improvements are needed to address this issue. Utility Model Content

[0005] The purpose of this utility model is to solve the problems in the existing technology where most surface grinders use lead screws to drive the grinding equipment for surface grinding operations. However, the platform on which the grinding equipment is installed is only connected to the lead screw, which easily leads to uneven force distribution. When adjusting the equipment, the grinding equipment is prone to shaking, resulting in defective products and increasing economic losses for the user. Therefore, this utility model proposes a surface grinder lifting structure with better stability.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: a surface grinder lifting structure with good stability, including a table, a guide rail fixedly connected to the upper surface of the table, a drive motor fixedly connected to the top of the guide rail, a lead screw fixedly connected to the drive end of the drive motor, the lead screw being rotatably connected to the surface of the table, a mounting bracket slidably connected in the guide rail, the mounting bracket being sleeved on the lead screw, the lead screw being threadedly connected to the inner wall of the mounting bracket, a grinding disc being mounted on the surface of the mounting bracket, a stabilizing device being provided on the surface of the mounting bracket, the stabilizing device including an inclined rod, the inclined rod being fixedly connected to the lower surface of a mounting block, a stabilizing block being fixedly connected to the end of the inclined rod away from the mounting block, the stabilizing block being sleeved on the lead screw, the stabilizing block sliding against the inner wall of the guide rail, the lead screw being threadedly connected to the inner wall of the stabilizing block, and a protective device being provided on the surface of the stabilizing block. By setting the stabilizing device, it is convenient to provide stable support for the mounting bracket, ensure the stable operation of the equipment, reduce the occurrence of grinding disc vibration during equipment operation, reduce the probability of defective materials, reduce the economic losses of users, and facilitate the normal use of the equipment.

[0007] Preferably, a positioning plate is connected to one side of the mounting frame, a support plate is fixedly connected to the surface of the positioning plate, a carrier plate is fixedly connected to the end of the support plate away from the positioning plate, and a roller is rotatably connected to the inner wall of the carrier plate to provide stable support for the mounting frame and ensure stable operation of the equipment.

[0008] Preferably, there are two positioning plates, which are arranged symmetrically between each other.

[0009] Preferably, the number of rollers is three, and the three rollers are arranged at equal intervals. In use, the drive motor drives the lead screw to rotate, and then the mounting frame drives the grinding disc to move to perform grinding operation on the material. During this process, the stabilizing block and the positioning plate move together with the mounting frame, which can provide stable support for the mounting frame. At the same time, when the positioning plate is displaced, it drives the rollers to slide stably on the surface of the guide rail through the support plate and the carrier plate.

[0010] Preferably, the protective device includes a slider and a mounting groove. The mounting groove is located on the lower surface of the stabilizing block. The slider slides against the inner wall of the mounting groove. A stop plate is fixedly connected to the lower surface of the slider. The protective device facilitates protective operation of the grinding disc, reduces the probability of the grinding disc contacting the table surface, and reduces safety hazards during equipment use.

[0011] Preferably, a spring is fixedly connected to the upper surface of the slider. The spring is located in the mounting groove, and the end of the spring away from the slider is fixedly connected to the inner wall of the mounting groove. When the grinding disc is close to the table surface, the protective strip on the abutment plate contacts the table surface first, and then the abutment plate squeezes the slider. The spring is deformed by force. When the mounting frame moves upward to reset, the spring pushes out the slider and the abutment plate.

[0012] Preferably, the lower surface of the abutment is fixedly connected with multiple protective strips for cushioning.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] In this invention, during use, the drive motor rotates the lead screw, and then the mounting frame moves the grinding disc to perform grinding operations on the material. During this process, the stabilizing block and the positioning plate move together with the mounting frame, providing stable support for the mounting frame. At the same time, when the positioning plate is displaced, it drives the roller to slide stably on the surface of the guide rail through the support plate and the carrier plate. By setting up a stabilizing device, it is easy to provide stable support for the mounting frame, ensuring stable operation of the equipment, reducing the occurrence of grinding disc vibration during operation, reducing the probability of defective materials, reducing economic losses for users, and facilitating normal use of the equipment.

[0015] In this invention, when the grinding disc is about to approach the table surface, the protective strip on the abutment plate contacts the table surface first, and then the abutment plate squeezes the slider, causing the spring to deform under force. When the mounting bracket moves upward to reset, the spring pushes out the slider and the abutment plate. Through the protective device, it is convenient to perform protective operation on the grinding disc, reduce the probability of the grinding disc contacting the table surface, and reduce safety hazards during equipment use.

The rod 72 is fixedly connected to the lower surface of the mounting block. A stabilizing block 71 is fixedly connected to the end of the inclined rod 72 away from the mounting block. The stabilizing block 71 is sleeved on the lead screw 6. The stabilizing block 71 slides against the inner wall of the guide rail 2. The lead screw 6 is threadedly connected to the inner wall of the stabilizing block 71. A protective device 8 is provided on the surface of the stabilizing block 71. By setting the stabilizing device, it is easy to provide stable support for the mounting frame 4, ensure the stable operation of the equipment, reduce the vibration of the grinding disc 3 during the operation of the equipment, reduce the probability of defective materials, reduce the economic losses of users, and facilitate the normal use of the equipment.

[0024] In this embodiment: a positioning plate 73 is connected to one side of the mounting frame 4, a support plate 74 is fixedly connected to the surface of the positioning plate 73, a carrier plate 76 is fixedly connected to the end of the support plate 74 away from the positioning plate 73, and a roller 75 is rotatably connected to the inner wall of the carrier plate 76 to provide stable support for the mounting frame 4 and ensure stable operation of the equipment.

[0025] Specifically, there are two positioning plates 73, which are arranged symmetrically between each other.

[0026] Specifically, there are three rollers 75, which are evenly spaced. In use, the drive motor 5 drives the lead screw 6 to rotate, and then the mounting frame 4 drives the grinding disc 3 to move to grind the material. During this process, the stabilizing block 71 and the positioning plate 73 move together with the mounting frame 4 to provide stable support for the mounting frame 4. At the same time, when the positioning plate 73 moves, it drives the rollers 75 to slide stably on the surface of the guide rail 2 through the support plate 74 and the carrier plate 76.

[0027] In this embodiment, the protective device 8 includes a slider 82 and a mounting groove 84. The mounting groove 84 is located on the lower surface of the stabilizing block 71. The slider 82 slides against the inner wall of the mounting groove 84. A stop plate 81 is fixedly connected to the lower surface of the slider 82. The protective device 8 facilitates the protective operation of the grinding disc 3, reduces the probability of the grinding disc 3 contacting the table surface 1, and reduces the safety hazards in the use of the equipment.

[0028] Specifically, a spring 83 is fixedly connected to the upper surface of the slider 82. The spring 83 is located in the mounting groove 84. The end of the spring 83 away from the slider 82 is fixedly connected to the inner wall of the mounting groove 84. When the grinding disc 3 is about to approach the table surface 1, the protective strip 85 on the abutment 81 contacts the table surface 1 first. Then the abutment 81 squeezes the slider 82, and the spring 83 is deformed by force. When the mounting bracket 4 moves upward to reset, the spring 83 pushes out the slider 82 and the abutment.

[0029] Preferably, a plurality of protective strips 85 are fixedly connected to the lower surface of the abutment plate 81 for cushioning operation.

[0030] Working Principle: During operation, the drive motor 5 drives the lead screw 6 to rotate, and then the mounting frame 4 moves the grinding disc 3 to grind the material. During this process, the stabilizing block 71 and the positioning plate 73 move together with the mounting frame 4, providing stable support for the mounting frame 4. At the same time, when the positioning plate 73 moves, it drives the roller 75 to slide stably on the surface of the guide rail 2 through the support plate 74 and the carrier plate 76. By setting up a stabilizing device, it is easy to provide stable support for the mounting frame 4, ensuring stable operation of the equipment, reducing the vibration of the grinding disc 3 during operation, reducing the probability of defective materials, reducing economic losses for users, and facilitating normal use of the equipment. When the grinding disc 3 is about to approach the table surface 1, the protective strip 85 on the abutment plate 81 contacts the table surface 1 first, and then the abutment plate 81 presses the slider 82, and the spring 83 deforms under force. When the mounting frame 4 moves upward to reset, the spring 83 pushes out the slider 82 and the abutment block. Through the protective device 8, it is easy to protect the grinding disc 3, reduce the probability of the grinding disc 3 contacting the table surface 1, and reduce safety hazards during use of the equipment.
