[0003] However, existing building material grinding machines have some shortcomings in actual use: 1. The clamping device of traditional building material grinding machines has a complex structure and is cumbersome to operate, making it difficult to quickly and accurately clamp building materials of different shapes and sizes; 2. Existing grinding machines are not flexible enough in adjusting the grinding position and angle, usually requiring a lot of manual adjustments, which not only wastes time and manpower, but also makes it difficult to guarantee the adjustment accuracy. Summary of the Invention

[0004] The main purpose of this utility model is to provide a convenient clamping grinding machine for building materials, which can effectively solve the problems in the background art.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

Support feet are fixedly connected to the four corners of the lower end of the main frame. A control button is provided on the front right side of the main frame. A clamping device is fixedly connected to the middle left side of the main frame. Electric telescopic rods are embedded in the upper left and upper right sides of the main frame. An adjustment device is fixedly connected to the output ends of the two electric telescopic rods.

[0007] The clamping device includes a cylinder, a second movable plate, and a gear. The cylinder is fixed to the left end of the main frame, and its output end is fixedly connected to the first movable plate through the main frame. The lower ends of the first and second movable plates are respectively provided with three sliding plates. Clamping blocks are fixedly installed on the upper inner sides of the first and second movable plates. The upper middle part of the upper end of the two clamping blocks is provided with a V-shaped clamping opening that runs vertically through the middle. Rectangular racks are installed on the lower inner sides of the first and second movable plates. The lower end of the gear is movably connected to the middle of the lower inner wall of the main frame through a bearing.

[0008] Preferably, the skateboard, the first movable plate, and the second movable plate are all manufactured using an integral molding process, and the six skateboards are connected in pairs to the three grooves.

[0009] By adopting the above technical solution, the sliding plate and the movable plate are integrally molded, resulting in a stable and high-strength structure, reducing potential risks associated with component connections. The six sliding plates are connected to the corresponding tracks in pairs, ensuring smooth and stable sliding of the first and second movable plates, making the clamping operation more reliable.

[0010] Preferably, the gear meshes with two rectangular racks.

[0011] By adopting the above technical solution, the gear and the rectangular rack mesh with each other, the linear motion of the first movable plate driven by the cylinder can be accurately transmitted to the second movable plate, so as to realize the synchronous reverse movement of the two and complete the material clamping action efficiently and stably.

[0012] Preferably, the adjusting device includes a U-shaped connecting frame, with a limiting groove formed on the lower inner wall of the U-shaped connecting frame. A rotary motor is fixedly connected to the right end of the U-shaped connecting frame, and a screw is fixedly connected to the output end of the rotary motor through the U-shaped connecting frame. A movable loop is threadedly connected to the outer surface of the screw, and a limiting plate is fixedly connected to the upper side of the outer surface of the movable loop. A grinding machine body is fixedly connected to the lower side of the outer surface of the movable loop. The lower left and lower right ends of the U-shaped connecting frame are respectively fixedly connected to the output ends of two electric telescopic rods.

[0013] By adopting the above technical solution: the adjustment device realizes the horizontal movement of the grinding machine body through a rotary motor and screw, and the vertical movement through an electric telescopic rod. With the help of the limiting groove and the limiting plate, the grinding position can be adjusted precisely and flexibly to meet different processing needs.

[0014] Preferably, the rotary motor is electrically connected to the control button.

[0015] By adopting the above technical solution, the rotary motor is electrically connected to the control button, allowing the operator to easily turn the rotary motor on, off, or adjust its speed at the control button, thereby precisely controlling the screw rotation and achieving convenient adjustment of the position of the grinding machine body.

[0016] Preferably, the limiting plate is disposed in the limiting groove, and the left end of the screw is movably connected to the left inner wall of the U-shaped connecting frame through a bearing.

[0017] By adopting the above technical solution: the limiting plate and the limiting groove cooperate to prevent the movable loop from rotating, allowing the grinding machine body to move smoothly in a straight line; the left end of the screw is connected by a bearing to ensure its flexible rotation and help to accurately adjust the grinding position.

[0018] Compared with the prior art, the present invention has the following beneficial effects:

[0019] In this invention, the clamping device uses a cylinder to push the first movable plate, which, in conjunction with the meshing transmission of gears and a rectangular rack, drives the second movable plate to move synchronously, achieving rapid clamping of building materials. This structure is simple and efficient. Furthermore, the cooperation between the sliding plate and the sliding groove ensures smooth movement of the movable plate, and the V-shaped clamping opening design can adapt to materials of different shapes, whether square stone, round pipes, or irregularly shaped wood, all can be firmly clamped. This solves the problems of traditional clamping devices being cumbersome to operate and difficult to adapt to materials of different shapes and sizes.

[0020] In this invention, the adjusting device includes an electric telescopic rod that adjusts the height of the U-shaped connecting frame, thus changing the vertical position of the grinder body. A rotary motor drives a screw to rotate, causing a movable loop to move the grinder body laterally along the screw. The limiting plate and limiting groove cooperate to ensure smooth movement. By controlling the electric telescopic rod and rotary motor via control buttons, the grinding position and angle can be precisely adjusted. Compared to extensive manual adjustments, this saves time and manpower, achieves higher adjustment accuracy, and meets diverse grinding needs. Attached Figure Description

[0029] Please see Figure 1-4 This utility model provides a technical solution:

[0030] A convenient clamping building material grinding machine includes a main frame 1. The lower inner wall of the main frame 1 has three sliding grooves 2. Support feet 3 are fixedly connected to the four corners of the lower end of the main frame 1. A control button 4 is provided on the front right side of the main frame 1. A clamping device 5 is fixedly connected to the middle of the left end of the main frame 1. Electric telescopic rods 6 are embedded and installed on the upper left and upper right sides of the main frame 1. An adjustment device 7 is fixedly connected to the output ends of the two electric telescopic rods 6.

[0031] In this embodiment, the clamping device 5 includes a cylinder 51, a second movable plate 53, and a gear 58. The cylinder 51 is fixed to the left end of the main frame 1, and its output end is fixedly connected to the first movable plate 52 through the main frame 1. The lower ends of the first movable plate 52 and the second movable plate 53 are respectively provided with three sliding plates 54. The upper inner side of the first movable plate 52 and the second movable plate 53 are respectively fixedly installed with clamping blocks 55. The upper middle part of the upper end of the two clamping blocks 55 is provided with a V-shaped clamping opening 56 that runs vertically through the middle. The lower inner side of the first movable plate 52 and the second movable plate 53 are respectively installed with rectangular racks 57. The lower end of the gear 58 is movably connected to the middle of the lower inner wall of the main frame 1 through a bearing. The sliding plates 54 are manufactured with the first movable plate 52 and the second movable plate 53 using an integral molding process. The six sliding plates 54 are respectively connected to the three sliding grooves 2 in pairs. The gear 58 is meshed with the two rectangular racks 57.

[0032] Through the above scheme: when it is necessary to clamp building materials, the operator activates the cylinder 51 fixed to the left end of the main frame 1 via the control button 4. The output end of the cylinder 51 drives the first movable plate 52, which is fixedly connected to it, to move. The slide plate 54, which is integrally formed at the lower end of the first movable plate 52 and the second movable plate 53, slides in the groove 2 on the inner wall of the main frame 1 to ensure the smooth movement of the movable plates. The rectangular rack 57 on the lower inner side of the first movable plate 52 and the second movable plate 53 meshes with the gear 58, which is movably connected to the middle of the inner wall of the main frame 1 via a bearing. When the cylinder 51 pushes the first movable plate 52 to move, its rectangular rack 57 drives the gear 58 to rotate, thereby driving the second movable plate 53 to move synchronously in the opposite direction. The clamping block 55 on the upper inner side of the first movable plate 52 and the second movable plate 53 has a V-shaped clamping port 56 at the middle of its upper end. When the movable plates move towards each other, it can adapt to different shaped building materials and clamp them firmly, which is convenient for subsequent grinding. When the material needs to be released, cylinder 51 moves in the opposite direction, the movable plate moves in the opposite direction, the clamping block 55 separates, and the material is released.

[0033] In this embodiment, the adjustment device 7 includes a U-shaped connecting frame 71. A limiting groove 72 is formed on the lower inner wall of the U-shaped connecting frame 71. A rotary motor 73 is fixedly connected to the right end of the U-shaped connecting frame 71. A screw 74 is fixedly connected to the output end of the rotary motor 73 through the U-shaped connecting frame 71. A movable loop 75 is threadedly connected to the outer surface of the screw 74. A limiting plate 76 is fixedly connected to the upper side of the outer surface of the movable loop 75. A grinding machine body 77 is fixedly connected to the lower side of the outer surface of the movable loop 75. The lower left and lower right ends of the U-shaped connecting frame 71 are fixedly connected to the output ends of two electric telescopic rods 6, respectively. The rotary motor 73 is electrically connected to the control button 4. The limiting plate 76 is disposed in the limiting groove 72. The left end of the screw 74 is movably connected to the left inner wall of the U-shaped connecting frame 71 through a bearing.

[0034] Through the above scheme: the adjusting device 7 is used to flexibly adjust the position of the grinding machine body 77. The operator controls the circuit connection with the rotary motor 73 through the control button 4. The rotary motor 73 is fixed to the right end of the U-shaped connecting frame 71. After starting, its output end drives the screw 74 fixedly connected to it to rotate. The left end of the screw 74 is movably connected to the left inner wall of the U-shaped connecting frame 71 through a bearing. The outer surface of the screw 74 is threaded with a movable loop 75. When the screw 74 rotates, the movable loop 75 will move linearly along the screw 74. To ensure the stability and accuracy of the movement of the movable lasso 75, a limiting plate 76 is fixedly connected to the upper side of its outer surface and is positioned within a limiting groove 72 formed on the lower inner wall of the U-shaped connecting frame 71. The limiting groove 72 guides and limits the limiting plate 76, preventing the movable lasso 75 from rotating with the screw 74 without moving linearly. Simultaneously, the lower side of the outer surface of the movable lasso 75 is fixedly connected to the grinding machine body 77. The linear movement of the movable lasso 75 drives the grinding machine body 77 to move horizontally, thereby achieving lateral adjustment of the grinding position. Furthermore, the lower left and lower right ends of the U-shaped connecting frame 71 are fixedly connected to the output ends of two electric telescopic rods 6, respectively. The operator controls the extension and retraction of the electric telescopic rods 6 via control button 4. The extension and retraction of the electric telescopic rods 6 causes the U-shaped connecting frame 71 to rise or fall, thereby moving the grinding machine body 77 vertically, achieving vertical adjustment of the grinding position. Through horizontal and vertical adjustments, the grinding machine body 77 can precisely reach the desired grinding position.

[0035] It should be noted that this utility model is a convenient clamping building material grinding machine. During use, first, the grinding machine is placed in a stable working area. The device is turned on using control button 4. The building material to be ground is placed between the two clamping blocks 55 of the clamping device 5. Control button 4 is pressed, and cylinder 51 starts, its output pushing the first movable plate 52 to move. Since gear 58 meshes with the rectangular rack 57 on the first movable plate 52 and the second movable plate 53, the movement of the first movable plate 52 drives gear 58 to rotate, thereby causing the second movable plate 53 to move synchronously in the opposite direction. The sliding plates 54 at the lower ends of the first and second movable plates 52 and 53 slide smoothly within the groove 2 on the inner wall of the main frame 1. Finally, the V-shaped clamping openings 56 on the two clamping blocks 55 firmly clamp the material. According to the grinding requirements of the building material, the electric telescopic rod 6 is extended or shortened using control button 4. The output of the electric telescopic rod 6 drives the U-shaped connecting frame 71 to rise or fall, thereby adjusting the vertical position of the grinding machine body 77. Next, control button 4 starts the rotary motor 73, whose output drives the screw 74 to rotate. The movable loop 75, threadedly connected to the screw 74, moves laterally along the screw 74. The limiting plate 76 on the movable loop 75 slides within the limiting groove 72 on the lower inner wall of the U-shaped connecting frame 71, ensuring the smooth movement of the movable loop 75. This precisely adjusts the lateral position and angle of the grinding machine body 77. After the position and angle are adjusted, the grinding machine body 77 is started to begin grinding. After grinding is completed, control button 4 is pressed to turn off the grinding machine body 77. Then, cylinder 51 is operated to release the clamping device 5, and the ground building material is removed. The power is turned off, and the equipment and work area are cleaned.
