Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-6 This utility model provides a technical solution: a positioning device for a surface grinder, comprising: The bed board 1 has mounting through holes 2 evenly distributed on its upper surface, and a device clamping component 3 is fixedly assembled in the mounting through holes 2. The lower end of the lifting mounting plate 4 is fixedly fitted with a mounting frame 5; The mounting frame 5 is equipped with clamping structures 6 at the front, back, left, and right. The lifting mounting plate 4 is equipped with a transverse guide structure 8 and a transverse drive structure 7 on the front and rear sides of its bottom. The upper front and rear sides of the mounting frame 5 are fixedly connected to the movable parts of the transverse guide structure 8 and the transverse drive structure 7, respectively.

[0025] Specifically in this embodiment, the rear side of the upper surface of the plate 1 is used to mount a grinding wheel rotating device; In this embodiment, the mounting through holes 2 are rectangular and are evenly distributed in the middle of the upper surface of the bed board 1. The mounting frame 5 is located outside the evenly distributed mounting through holes 2. Furthermore, the device clamping component 3 can be set in different mounting through holes 2. The device clamping component 3 is set around the outside of the device to be processed, and multiple device clamping components 3 are used to clamp the lower end of the outer wall of the device. When the device to be processed is high, the mounting frame 5 is raised and lowered to a suitable height by the lifting mounting plate 4. The clamping structure 6 distributed in the front, back and left and right of the mounting frame 5 is used to clamp and position the upper end of the outer wall of the device to be processed, thereby improving the stability of clamping and fixing.

[0026] More specifically, the lateral guide structure 8 and the lateral drive structure 9 are set to drive and guide the mounting frame 5 to the mounting position on the bottom surface of the lifting mounting plate 4, thereby causing the clamping positions of the four clamping structures 6 to change accordingly, which can adjust the position of the device to be processed and make it easier to process it at different positions. It is understandable that drilling equipment, cutting equipment, welding equipment, and other processing equipment of suitable size can be installed on the bed board 1 to replace the installation position of the grinding wheel rotating device, so that the device can be used for clamping and positioning of the device in different processing scenarios.

[0027] In some embodiments, the mounting frame 5 includes: A rectangular frame 51 has connecting rods 52 vertically fixedly assembled at the middle of the front and rear sides of its upper edge; The upper ends of the front and rear connecting rods 52 are fixedly connected to the movable parts of the transverse guide structure 8 and the transverse drive structure 7, respectively.

[0028] Specifically, in this embodiment, the rectangular frame 51 is a rectangular ring structure with openings on both the top and bottom sides; Furthermore, pre-drilled screw holes and pre-drilled through holes are provided in the middle of the left and right side walls and the front and rear side walls of the rectangular frame 51 for the installation of the clamping structure 6. More specifically, there are two connecting rods 52 on one side of the upper edge of the rectangular frame 51. These two connecting rods 52 are located on the left and right sides of the upper edge of one side of the rectangular frame 51, which improves the stability of the connection and fixation.

[0029] In some embodiments, the lateral drive structure 7 includes: The first strip groove 71 is horizontally opened on the rear side of the bottom surface of the lifting mounting plate 4; One end of the first screw 72 is rotatably connected to the left side of the inner wall of the first strip groove 71, and the other end extends through the right side wall of the first strip groove 71 to the outside. A first slider 73 is screwed to the middle of the outer wall of the first screw 72, and it is slidably assembled in the first strip groove 71. The bottom surface of the first slider 73 is fixedly connected to the rear side of the upper end of the mounting frame 5; The lateral guide structure 8 includes: The second strip groove 81 is horizontally opened on the front side of the bottom of the lifting mounting plate 4; A round rod 82 is laterally rotatably connected to the inner wall of the second strip groove 81; A second slider 83 is slidably sleeved in the middle of the outer wall of the round rod 82, and it is slidably assembled in the second strip groove 81. The bottom surface of the second slider 83 is fixedly connected to the front side of the upper end of the mounting frame 5.

[0030] Specifically in this embodiment, the outer wall of the first slider 73 is slidably fitted with the inner wall of the first strip groove 71; the outer wall of the second slider 83 is slidably fitted with the inner wall of the second strip groove 81. Furthermore, by rotating the first screw 72 to extend the first strip groove 71, the first slider 73 on the outer wall of the first screw 72 is driven to move left and right along the first strip groove 71, thereby causing the upper rear side of the mounting frame 5 fixed by the first slider 73 to move laterally. The second slider 83 on the upper front side of the mounting frame 5 slides on the outer wall of the round rod 82 to guide the lateral movement of the mounting frame 5. Understandably, the end of the first screw 72 extending out of the first strip groove 71 is provided with a hand-tightening round cap, which makes it convenient to grip and rotate the first screw 72.

[0031] In some embodiments, the device holder 3 includes: A flat plate 31, on the middle of its upper surface, is fixedly fitted with a vertical plate 32; A third screw 36 is screwed to the middle of the left and right side walls of the upright plate 32; The third screw 36 is rotatably fitted with the first clamping plate 33 at one end, and its lower end slides against the upper surface of the plate 31. A fourth screw 34 is vertically fixed to the bottom surface of the plate 31, and a fixing nut 35 is screwed onto its outer wall. The fixing nut 35 rests against the bottom surface of the bed board 1.

[0032] Specifically in this embodiment, the outer diameter of the fourth screw 34 is smaller than the inner diameter of the mounting through hole 2, and the outer diameter of the fixing nut 35 is larger than the inner diameter of the mounting through hole 2. Furthermore, during use, the fourth screw 34 is inserted into the mounting through hole 2 where it needs to be installed, and the fixing nut 35 is screwed into the lower end of the fourth screw 34 until it abuts against the bottom surface of the bed plate 1 where the mounting through hole 2 is located, so as to achieve the fixed installation of the device clamping part 3. The disassembly can be performed by reversing the operation, which makes it easy to adjust the fixed position of the device clamping part 3. More specifically, when using clamping, rotating the third screw 36 drives the first clamping plate 33 to move left and right along the plate 31. The first clamping plate 33 of the device clamping member 3 in multiple directions abuts against the lower end of the outer wall of the device to be clamped, which can clamp and position the lower end of the device to be clamped. When it is necessary to release the positioning, the operation is reversed. It is understandable that the fixed position of the device clamping member 3 in the mounting through hole 2 can be tilted, so that the device clamping member 3 is not set horizontally, and its clamping end can abut against the inclined outer wall of the irregular device, thereby improving practicality.

[0033] In some embodiments, the lifting mounting plate 4 includes: Mounting plate 41 is located directly above bed board 1; A hydraulic cylinder 42 is vertically fixedly mounted on the top center of the mounting plate 41, with its upper end fixedly installed.

[0034] Specifically in this embodiment, the hydraulic cylinder 42 is connected to an external hydraulic system, which is an existing technology application. The hydraulic cylinder 42 drives the mounting plate 41 to rise and fall, which in turn drives the mounting frame 5 to rise and fall. The height of the clamping structure 6 is adjusted according to the different heights of the workpiece to be processed. It is understandable that the upper end of the hydraulic cylinder 42 is fixed on the factory ceiling or other high-altitude mounting surface. If there is no suitable mounting surface, a corresponding mounting bracket can be designed as needed to fix the upper end of the hydraulic cylinder 42.

[0035] In some embodiments, a lifting guide structure 9 is installed between the bottom surface of the lifting mounting plate 4 and the upper surface of the bed board 1; The lifting guide structure 9 includes: The first guide rod 92 is vertically fixedly assembled at the four corners of the upper surface of the bed board 1; Through holes 91 are provided at all four corners of the lifting mounting plate 4; The upper end of the first guide rod 92 passes through the corresponding through hole 91.

[0036] Specifically, in this embodiment, the mounting plate 41 at the lower end of the lifting mounting plate 4 is a rectangular plate; the first guide rod 92 slides against the inner wall of the through hole 91; Furthermore, the mounting plate 41 is designed to move up and down along the outer wall of the vertically fixed first guide rod 92 through the through hole 91, which guides the movement of the mounting plate 41. Understandably, when the lifting mounting plate 4 is subjected to impact or collision, the first guide rod 92 in the through hole 91 can effectively prevent the lifting mounting plate 4 from shifting its position.

[0037] In some embodiments, a limiting block is integrally formed at the upper end of the first guide rod 92. The limiting block limits the lowest position of the first guide rod 92 as it descends, preventing the first guide rod 92 from coming out of the through hole 91.

[0038] In some embodiments, the clamping structure 6 includes: The fifth screw 61 is vertically screwed to the middle of the front, rear, left and right side walls of the mounting frame 5; The end of the fifth screw 61 located within the mounting frame 5 is rotatably fitted with the second clamping plate 62; The second guide rod 63 is vertically fixed to the outer edge of the second clamping plate 62, and its outer end passes through the same side of the mounting frame 5.

[0039] Specifically in this embodiment, rubber pads are attached to the surfaces of the second clamping plate 62 and the first clamping plate 33 that are in contact with the device to avoid direct contact with the outer wall of the device and cause wear to the device. Furthermore, rotating the fifth screw 61 drives the second clamping plate 62 to move along the guiding direction of the second guide rod 63; Adjust the multiple second clamping plates 62 to move inward and abut against the upper end of the outer wall of the workpiece to clamp and position the upper end of the workpiece. When it is necessary to release the positioning, reverse the operation. More specifically, the fifth screw 61 is screwed into the reserved screw hole on the same side of the outer wall of the mounting frame 5, and the second guide rod 63 is slidably inserted into the reserved through hole on the same side of the outer wall of the mounting frame 5, with the outer wall of the second guide rod 63 slidingly fitting against the inner wall of the reserved through hole.

[0040] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
