[0031] To further understand the content of the present utility model, the present utility model will be described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are only for explaining the present utility model and not for limiting it.

[0032] The following combines the attached Figures 1-5 This embodiment will be further described in detail.

[0033] As Figure 1 shown, a grinding machine for processing parts in this embodiment includes a workbench 100. Opposite mounting plates 110 are provided on the upper end surface of the workbench 100 at the front and rear sides. A grinding assembly for grinding parts is provided on the mounting plate 110 at the rear side. A slidable sliding plate 120 is provided between the two mounting plates 110. A bottom plate 130 is sleeved on the sliding plate 120. Opposite and movable driving plates 140 are provided on the bottom plate 130. A connecting assembly is provided on the lower end surface of the bottom plate 130. When one of the two driving plates 140 moves, the connecting assembly drives the other driving plate 140 to move relatively. A switchable clamping plate is provided on the driving plate 140. The two driving plates 140 approach each other to drive the two clamping plates to clamp workpieces of different shapes. A positioning assembly for positioning the movement of the driving plate 140 is provided on the bottom plate 130. A moving assembly for driving the bottom plate 130 to move along the sliding plate 120 is provided on the workbench 100.

[0034] In this embodiment, by placing the parts to be ground on the bottom plate 130, then driving one of the two driving plates 140 to move. At this time, the connecting assembly drives the other driving plate 140 to move relatively, realizing the mutual approach of the two driving plates 140. When the two driving plates 140 approach each other, the clamping plates on the two driving plates abut against the parts. Then, the position of the driving plate 140 is positioned through the positioning assembly, realizing the clamping and fixing of the parts on the bottom plate 130 by the two clamping plates. At this time, the surface of the parts can be ground through the grinding assembly;

[0035] Among them, both mounting plates 110 are fixedly installed on the workbench 100. Sliders 160 are fixedly installed on the two mounting plates 110 along their length directions. A chute 381 is formed on the sliding plate 120. When the slider 160 is snapped into the corresponding chute 381, the sliding plate 120 is slidably installed between the two mounting plates 110. At this time, when the grinding assembly grinds the part, the sliding of the sliding plate 120 can drive the bottom plate 130 to move, so that the part clamped and fixed on the bottom plate 130 moves left and right under the grinding assembly, so that the surface of the part located under the grinding assembly can be evenly ground;

[0036] Among them, when the part is evenly ground under the grinding assembly by moving left and right, there will be positions on the part that cannot be reached by the grinding assembly. At this time, the moving assembly drives the bottom plate 130 to move back and forth along the sliding plate 120, so that the part on the bottom plate 130 moves with the bottom plate 130. At this time, the unground surface of the part can be located under the grinding assembly. Then, the grinding assembly can grind the unground surface. When the grinding assembly grinds the unground surface, the sliding plate 120 slides again, so that the grinding assembly can better grind the surface of the part;

[0037] Among them, a handle 121 is fixedly installed on the sliding plate 120, and it is convenient to drive the sliding plate 120 to slide between the two mounting plates 110 through the handle 121;

[0038] Among them, when grinding parts of different shapes is required, the clamping plates on the driving plate 140 are switched. When the driving plate 140 drives the two clamping plates to approach each other, the two clamping plates can clamp and fix parts of different shapes. Compared with the existing ones, when this grinding machine for processing parts is actually used, parts of different shapes can be clamped and fixed on the bottom plate 130, and the practicability is better during actual use;

[0039] During its actual use, the grinding assembly includes a support plate 170 fixedly installed on the rear mounting plate 110. A cross plate 171 is fixedly installed on the upper end surface of the support plate 170. An electric telescopic rod 172 is fixedly installed on the cross plate 171. The lower end of the electric telescopic rod 172 penetrates through the cross plate 171. The lower end of the electric telescopic rod 172 is fixedly installed with a grinding seat 173. A motor 174 is fixedly installed on the side wall of the grinding seat 173. A grinding wheel 175 is installed on the output shaft of the motor 174. The grinding seat 173 can be driven to move up and down by the electric telescopic rod 172. When the grinding wheel 175 on the grinding seat 173 abuts against the part, the motor 174 drives the grinding wheel 175 to rotate to grind the part.

[0040] Such as Figures 1-5As shown, in this embodiment, one end of the driving plate 140 is bent downward to form a bending portion 300. Rack bars 400 with one end extending beyond the lower end surface of the bottom plate 130 are provided at both ends of the bending portion 300. The two rack bars 400 on the two bending portions 300 are arranged in a staggered manner.

[0041] The connecting component includes round rods 410 that are relatively arranged on the lower end surface of the bottom plate 130 and can rotate. Gears 420 that mesh with the two rack bars 400 are provided on the round rods 410. The movement of one of the two driving plates 140 is used to drive the rotation of the gear 420, and the rotation of the gear 420 is used to drive the relative movement of the other driving plate 140.

[0042] In this embodiment, as Figure 4 shown, through the settings of the bending portion 300, the rack bar 400, the round rod 410, and the gear 420, by fixedly installing the rack bar 400 on the bending portion 300, the rack bar 400 is fixedly installed on the bending portion 300, the round rod 410 is rotatably installed on the bottom plate 130 through a bearing, the gear 420 is fixedly installed on the round rod 410. When one of the two driving plates 140 drives the driving plate 140 to move, one end of the driving plate 140 can drive the corresponding rack bar 400 to move through the bending portion 300. When the rack bar 400 moves, the movement of the rack bar 400 will drive the gear 420 to rotate. When the gear 420 rotates, the rotation of the gear 420 will drive the rack bar 400 on the other driving plate 140 to move. In actual use, when the part is placed at the center position of the bottom plate 130, by driving one driving plate 140 to move, the clamping plates on the two driving plates 140 can be made to abut against the part to clamp the part, which is more convenient to use.

[0043] In actual use, in combination with Figure 3 shown, a slot 391 with both ends open is formed on the upper end surface of the bottom plate 130 along the moving direction of the driving plate 140. A clamping block 540 is fixedly installed on the driving plate 140. The cross-sections of the slot 391 and the clamping block 540 are both T-shaped. By inserting one end of the clamping block 540 into the slot 391, the sliding installation of the driving plate 140 on the bottom plate 130 can be realized.

[0044] As Figures 1-5 shown, in this embodiment, a positioning groove 311 is formed on one of the two driving plates 140 along its moving direction.

[0045] The positioning component includes a positioning rod 320 that is arranged on the bottom plate 130 and has one end passing through the positioning groove 311. A positioning ring 321 is sleeved on the positioning rod 320. The positioning ring 321 is used to abut against the driving plate 140 to realize the positioning of the sliding of the driving plate 140 by the positioning ring 321.

[0046] In this embodiment, through the settings of the positioning groove 311, the positioning rod 320, and the positioning ring 321, the positioning rod 320 is threadedly installed on the bottom plate 130. When the two driving plates 140 are moved to appropriate positions and the two clamping plates abut against the part, by rotating the positioning ring 321 on the positioning rod 320, the positioning ring 321 is tightened against the driving plate 140, thereby realizing the positioning of the position of the driving plate 140 by the positioning ring 321. At this time, the two clamping plates can always maintain the clamping and fixing of the part.

[0047] Among them, when the position of one of the two driving plates 140 is positioned, the position of the other driving plate 140 can also be positioned through the connecting component, thereby avoiding the situation that the other driving plate 140 is not positioned, resulting in the clamping plate on the other driving plate 140 being unable to clamp the part.

[0048] Among them, by rotating the positioning ring 321 to release the tightening of the driving plate 140, the positioning of the driving plate 140 can be released.

[0049] Among them, when the driving plate 140 slides, one end of the positioning rod 320 is always located in the positioning groove 311, so that the positioning rod 320 can limit the sliding distance of the driving plate 140, thereby preventing the driving plate 140 from sliding out of the bottom plate 130 and affecting the actual use.

[0050] During actual use, when the grinding wheel 175 grinds the part, debris may accumulate in the card slot 391. The debris in the card slot 391 may affect the sliding of the card block 540 in the card slot 391. By rotating the positioning rod 320 out of the bottom plate 130, one end of the positioning rod 320 is not located in the positioning groove 311. At this time, by sliding the two driving plates 140 out of the bottom plate 130, the debris in the card slot 391 can be cleaned.

[0051] As Figures 1-4 shown, in this embodiment, mounting grooves 111 penetrating through the mounting plates 110 are provided along the length direction of the two mounting plates 110, mounting blocks 200 are provided in the two mounting grooves 111, and a support 210 is provided on the lower end surface of the bottom plate 130.

[0052] The moving component includes a lead screw 230 disposed between the two mounting blocks 200 and threadedly penetrating through the support 210. The lead screw 230 is rotatably arranged, and the rotation of the lead screw 230 is used to drive the support 210 to move, realizing the movement of the bottom plate 130 along the slide plate 120.

[0053] In this embodiment, through the settings of the installation groove 111, the installation block 200, the support 210, and the lead screw 230, the support 210 is fixedly installed on the bottom plate 130, and both ends of the lead screw 230 are rotatably installed on the corresponding installation blocks 200 through the support 210. When the lead screw 230 rotates threadedly, the support 210 can drive the bottom plate 130 to move along the sliding plate 120, so that the grinding assembly can grind the unground surface of the part;

[0054] Among them, both ends of the lead screw 230 extend outside the installation block 200, and installation rings 220 that abut against the side wall of the installation plate 110 are threadedly installed on the extended ends of the lead screw 230. The two ends of the lead screw 230 are limited by the installation rings 220, so that the two installation blocks 200 can always slide within the corresponding installation grooves 111, thus preventing the two installation blocks 200 from sliding out of the corresponding installation grooves 111 and affecting the actual use;

[0055] During actual use, a hand crank 150 is fixedly installed on the extended end of one end of the lead screw 230, and the hand crank 150 is used to facilitate driving the lead screw 230 to rotate.

[0056] As Figures 1-5 shown, in this embodiment, the clamping plate includes a fixing rod 330 provided on the upper end surface of the driving plate 140. A rotatable fixing ring 500 is sleeved on the fixing rod 330. A plurality of mounting rods 340 are provided along the circumference of the fixing ring 500. Adaptation blocks 341 adapted to different parts are respectively provided on the mounting rods 340. The fixing ring 500 rotates to switch different adaptation blocks 341. A locking member for locking the rotation of the fixing ring 500 is also provided on the positioning rod 320.

[0057] In this embodiment, through the settings of the fixing rod 330, the fixing ring 500, the mounting rod 340, the adaptation block 341, and the locking member, the fixing rod 330 is fixedly installed on the upper end surface of the driving plate 140, the fixing ring 500 is rotatably installed on the fixing rod 330 through a bearing, the mounting rod 340 is fixedly installed on the fixing ring 500, and the adaptation block 341 is fixedly installed on the corresponding mounting plate 110. When clamping parts of different shapes is required, the fixing ring 500 is driven to drive the mounting rod 340 to rotate, so that the adaptation blocks 341 on the two driving plates 140 and adapted to the parts all face the part. Then, the rotation of the fixing ring 500 is locked by the locking member, so that the adaptation blocks 341 adapted to the part always face the part. At this time, by moving the two driving plates 140 closer to each other, the two adaptation blocks 341 can be driven to clamp and fix the part;

[0058] During actual use, when the locking member releases the locking of the fixing ring 500, the fixing ring 500 can continue to drive the mounting rod 340 to rotate, so that the adapter block 341 facing the part can be switched, so that the adapter block 341 can clamp and fix parts of different shapes.

[0059] As Figures 1-5 shown, in this embodiment, an intercepting plate 350 is provided at the upper end of the fixing rod 330. A plurality of fixing holes 501 are formed in the upper end surface of the fixing ring 500 along its circumference, and a jack 511 is formed in the upper end surface of the driving plate 140.

[0060] The locking member includes a locking ring 360 sleeved on the fixing rod 330. A plug rod 520 is provided at the lower end surface of the locking ring 360 and located at the edge. A spring 370 for driving the locking ring 360 to move downward is sleeved on the fixing rod 330 between the locking ring 360 and the intercepting plate 350. The downward movement of the locking ring 360 is used to drive the lower end of the plug rod 520 to pass through the corresponding fixing hole 501 and insert into the corresponding jack 511 to lock the rotation of the fixing ring 500.

[0061] In this embodiment, through the settings of the intercepting plate 350, the fixing holes 501, the jacks 511, the locking ring 360, the plug rod 520 and the spring 370, the plug rod 520 is fixedly installed on the locking ring 360, and the intercepting plate 350 is fixedly installed on the fixing rod 330. The spring 370 and the locking ring 360 on the fixing plate are intercepted by the intercepting plate 350 to realize the installation of the locking ring 360 and the spring 370 in the fixed installation. When the fixing ring 500 drives the adapter block 341 on the mounting rod 340 to face the part, the fixing holes 501 on the fixing ring 500 are communicated with the jacks 511. At this time, the spring 370 pushes the plug rod 520 on the locking ring 360 to move downward, so that the lower end of the plug rod 520 penetrates through the jack 511 on the fixing ring 500, and the lower end of the plug rod 520 is inserted into the jack 511, so as to lock the rotation of the fixing ring 500, so that the adapter block 341 adapted to the part can clamp and fix the part.

[0062] Among them, by moving the locking ring 360 upward, the lower end of the plug rod 520 on the locking ring 360 slides out of the end jack 511, so as to release the locking of the fixing ring 500. At this time, by driving the mounting rod 340 to rotate by the fixing ring 500, the adapter block 341 can be switched.

[0063] During actual use, a dial block 530 is fixedly installed on the locking ring 360. The dial block 530 is convenient for driving the locking ring 360 to move upward, so as to facilitate actual use.

[0064] Working principle: First, place the part to be polished on the bottom plate 130. Then, release the locking of the fixing ring 500 by the locking member, so that the fixing ring 500 drives the mounting rod 340 to rotate, and then the fitting block 341 adapted to the part faces the part. Then, lock the rotation of the fixing ring 500 through the locking member. At this time, drive one of the two driving plates 140 to move, so that the fitting blocks 341 on the two driving plates 140 abut against the part. Then, position the driving plate 140 through the positioning component to realize the clamping and fixing of the part by the fitting block 341. Then, polish the surface of the part through the polishing component. When the part is polished, drive the sliding plate 120 to move through the handle 121, so that the polishing component can polish the part. Move the position of the bottom plate 130 through the moving component, so that the polishing component can polish different positions on the upper surface of the part to improve the polishing effect. When the polishing of the part is completed, release the positioning of the driving plate 140 by the positioning component, and the polished part can be taken out.
