Description

Technical Field

[0001] This utility model belongs to the field of bucket grinding technology, specifically relating to a bucket grinding device with a protective structure. Background Technology

[0002] The bucket is a core structural component of an excavator, used for digging loose materials such as soil, sand, gravel, and construction waste. Its design, materials, and functional classification directly affect operational efficiency and applicability. The bucket consists of components such as tooth base plates, bottom plates, side plates, wall plates, lug plates, back plates, bucket lug plates, bucket lug sleeves, bucket teeth, tooth bases, and guard plates or bucket corners, all connected by welding. The welding quality directly affects the structural strength and service life of the bucket, requiring specialized equipment such as CNC plasma cutting machines and welding positioners for processing.

[0003] The core purpose of grinding the inner wall of the bucket ear plate during bucket production is to eliminate processing defects, improve dimensional accuracy, and reduce surface roughness, thereby ensuring the fit quality between the bucket ear and the pin and extending the service life of the bucket.

[0004] When existing bucket ear covers are polished using a polishing device, the special location and limited space of the bucket ear cover make it difficult for the polishing device to implement comprehensive and effective protective measures for the surrounding area during operation. This results in the polished area lacking necessary protection, which poses certain safety risks to the entire polishing process. Utility Model Content

[0005] The purpose of this utility model is to provide a bucket grinding device with a protective structure, which aims to solve the problem that in the prior art, grinding devices are difficult to implement comprehensive and effective protective measures for the surrounding area during operation, resulting in a lack of necessary protection for the grinding part, which makes the entire grinding process pose certain safety risks.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a bucket grinding device with a protective structure, comprising: an outer frame for support on the outside, a side frame connected to the side surface of the outer frame, a transverse moving assembly installed on the side surface of the side frame and extending into the interior, and a grinding part installed on the inner wall of the side frame by an adjusting rotating assembly, wherein the inner wall of the outer frame is connected to a clamping assembly for clamping and fixing. The clamping assembly includes a clamping part installed on the inner wall of the outer frame, a linkage part located at the bottom of the clamping part, and a driving part connected to the surface of the outer frame and connected to the clamping part. The adjusting rotation assembly includes a rotating part connected to the transverse moving assembly and an adjusting part installed inside the rotating part and connected to the grinding part.

[0007] As a preferred embodiment of the excavator bucket grinding device with protective structure of this utility model, the clamping part includes an upper clamping plate and a lower clamping plate disposed on the inner wall of the outer frame, and a screw tube that is respectively connected to both sides of the upper clamping plate and the lower clamping plate. A double-acting screw rod is respectively inserted inside the two screw tubes on the same side of the upper clamping plate and the lower clamping plate. The two double-acting screw rods are respectively installed on the inner wall of the outer frame through bearing seats, and sliders are respectively connected to both ends of the upper clamping plate and the lower clamping plate, as well as sliding grooves respectively opened on both sides of the inner wall of the outer frame.

[0008] As a preferred embodiment of the bucket grinding device with protective structure of this utility model, the linkage part includes pulleys respectively connected to the ends of two bidirectional lead screws and belt rings sleeved on the surfaces of the two pulleys.

[0009] As a preferred embodiment of the bucket grinding device with protective structure of this utility model, the drive unit includes a driven bevel gear connected to the top of the bidirectional lead screw, a first drive motor mounted on the upper surface of the outer frame, and an active bevel gear connected to the output end of the first drive motor and meshing with the driven bevel gear.

[0010] As a preferred embodiment of the bucket grinding device with protective structure of this utility model, the rotating part includes a cylinder connected to the movable end of the transverse component, a first bearing ring sleeved on the end surface of the cylinder, a circular tube sleeved on the surface of the first bearing ring, a gear ring connected to the surface of the circular tube, a second drive motor installed on the bottom side of the cylinder, and a gear connected to the output end of the second drive motor and meshing with the gear ring.

[0011] As a preferred embodiment of the bucket grinding device with protective structure of this utility model, the adjusting part includes a guide rod connected to the inner wall of the circular tube and penetrating the inner wall of the grinding part, a second bearing ring fitted and installed on the surface of the circular tube, and an adjusting screw penetrating and connecting the second bearing ring and the inside of the grinding part. The adjusting screw and the grinding part are threadedly connected, and the center line of the adjusting screw is parallel to the center line of the guide rod.

[0012] As a preferred embodiment of the bucket grinding device with protective structure of this utility model, the transverse movement component includes a guide portion connected to both sides of the cylinder and a telescopic rod that penetrates and is installed on the inner wall of the side frame and connected to the cylinder. The guide section includes guide rails connected to both sides of the inner wall of the side frame and guide sleeves connected to both sides of the cylinder and adapted to the guide rails.

[0013] Compared with the prior art, the beneficial effects of this utility model are: In this invention, when the first drive motor is running, it drives the active bevel gear to rotate. When the active bevel gear rotates, it drives the bidirectional lead screw to rotate through the driven bevel gear. When the bidirectional lead screw rotates, it drives another bidirectional lead screw to rotate through the pulley and belt ring.

When the upper clamping plate and the lower clamping plate move to the surface of both sides of the ear sleeve, the device can be fixedly installed on the surface of the ear sleeve. This can realize automatic polishing without manual handling, thereby achieving a protective effect.

[0014] In this invention, when the adjusting screw rotates, it drives the grinding part to move axially. When the grinding head of the grinding part contacts the inner wall of the bucket ear sleeve, the inner wall of the bucket ear sleeve can be ground by the grinding part, thus adapting to the grinding of the inner wall of bucket ear sleeves with different inner diameters.

[0015] In this invention, the second drive motor can drive the gear to rotate during operation. The rotation of the gear drives the round tube to rotate through the gear ring. When the round tube rotates, it can drive the grinding part to rotate on the inner wall of the ear sleeve through the adjustment part. In conjunction with the extension of the telescopic rod, it drives the cylinder to move laterally. The lateral movement of the cylinder drives the round tube to move laterally through the first bearing ring. In this way, by driving the grinding part to move laterally, the inside of the ear sleeve can be fully ground. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figures 1-5 The present invention provides the following technical solution: a bucket grinding device with a protective structure, comprising: an outer frame 11 for support on the outside, a side frame 12 connected to the side surface of the outer frame 11, a transverse moving component 4 installed on the side surface of the side frame 12 and extending into the inside, and a grinding part 13 installed on the inner wall of the side frame 12 by adjusting the rotation component 3, wherein the inner wall of the outer frame 11 is connected to a clamping component 2 for clamping and fixing. The clamping assembly 2 includes a clamping part 21 installed on the inner wall of the outer frame 11, a linkage part 22 provided at the bottom of the clamping part 21, and a driving part 23 connected to the surface of the outer frame 11 and connected to the clamping part 21. The adjusting rotation assembly 3 includes a rotating part 31 connected to the transverse moving assembly 4 and an adjusting part 32 installed inside the rotating part 31 and connected to the grinding part 13.

[0020] Preferably, the clamping part 21 includes an upper clamping plate 211 and a lower clamping plate 212 disposed on the inner wall of the outer frame 11, and threaded tubes 213 respectively connected to both sides of the upper clamping plate 211 and the lower clamping plate 212. A double-acting screw 214 is respectively inserted inside the two threaded tubes 213 on the same side of the upper clamping plate 211 and the lower clamping plate 212. The two double-acting screws 214 are respectively installed on the inner wall of the outer frame 11 through bearing seats 215. Slider blocks 216 are respectively connected to both ends of the upper clamping plate 211 and the lower clamping plate 212, and sliding grooves 217 are respectively opened on both sides of the inner wall of the outer frame 11.

[0021] In practical use, when the bidirectional lead screw 214 rotates, it can drive the two solenoids 213 to move closer to each other. When the two solenoids 213 move, they can drive the upper clamping plate 211 and the lower clamping plate 212 to move closer to each other. When the upper clamping plate 211 and the lower clamping plate 212 move, they can respectively drive the slider 216 to slide inside the slide groove 217, thereby restricting the movement direction of the upper clamping plate 211 and the lower clamping plate 212 and maintaining the stability of the movement.

[0022] Preferably, the linkage 22 includes pulleys 221 connected to the ends of two bidirectional lead screws 214 and belt rings 222 sleeved on the surfaces of the two pulleys 221.

[0023] In practical use, when the bidirectional lead screw 214 rotates, it can drive the pulley 221 to rotate. When the pulley 221 rotates, it can drive another pulley 221 to rotate through the belt ring 222, which in turn can drive the other bidirectional lead screw 214 to rotate through the pulley 221.

[0025] In practical use, when the first drive motor 232 is running, it can drive the active bevel gear 233 to rotate. When the active bevel gear 233 rotates, it can drive the driven bevel gear 231 to rotate through the meshing structure. When the driven bevel gear 231 rotates, it can drive the bidirectional lead screw 214 to rotate inside the bearing housing 215.

[0027] In practical use, when the second drive motor 315 is running, it can drive the gear 316 to rotate. The rotation of the gear 316 drives the gear ring 314 to rotate through the meshing structure. When the gear ring 314 rotates, it can drive the round tube 313 to rotate on the surface of the first bearing ring 312.

[0028] Preferably, the adjusting part 32 includes a guide rod 321 connected to the inner wall of the round tube 313 and penetrating the inner wall of the grinding part 13, a second bearing ring 322 fitted onto the surface of the round tube 313, and an adjusting screw 323 penetrating and connecting the second bearing ring 322 and the interior of the grinding part 13. The adjusting screw 323 and the grinding part 13 are threadedly connected, and the center line of the adjusting screw 323 is parallel to the center line of the guide rod 321.

[0029] In practical use, when the adjusting screw 323 rotates, it can drive the grinding part 13 to move axially through the threaded connection. When the grinding part 13 moves axially, it can slide on the surface of the guide rod 321, thereby adjusting the position of the grinding part 13 to adapt to ear sleeves with different inner diameters.

[0030] Preferably, the transverse moving assembly 4 includes a guide portion 41 connected to both sides of the cylinder 311 and a telescopic rod 42 that penetrates the inner wall of the side frame 12 and is connected to the cylinder 311; The guide section 41 includes guide rails 411 connected to both sides of the inner wall of the side frame 12 and guide sleeves 412 connected to both sides of the cylinder 311 and adapted to the guide rails 411.

[0031] In practical use, when the telescopic rod 42 is running, it can drive the cylinder 311 to move laterally. When the cylinder 311 moves laterally, it can drive the round tube 313 to move laterally through the first bearing ring 312. When the round tube 313 moves laterally, it can drive the grinding part 13 to move laterally through the adjusting part 32, thereby adjusting the lateral position of the grinding part 13.

[0032] Working principle: When using this bucket grinding device, firstly, the upper clamping plate 211 and lower clamping plate 212 are fitted onto the two sides of the protruding bucket ear sleeve by the outer frame 11. Then, the first drive motor 232 can be run. When the first drive motor 232 runs, it drives the active bevel gear 233 to rotate. When the active bevel gear 233 rotates, it drives the double-acting screw 214 to rotate through the driven bevel gear 231. When the double-acting screw 214 rotates, it drives the other double-acting screw 214 to rotate through the pulley 221 and belt ring 222. When the double-acting screw 214 rotates, it drives the upper clamping plate 211 and lower clamping plate 212 to move towards each other through the two solenoids 213. When the upper clamping plate 211 and lower clamping plate 212 move to the surface of the bucket ear sleeve respectively, the device can be fixedly installed on the surface of the bucket ear sleeve. Next, the telescopic rod 42 can be operated. When the telescopic rod 42 extends, it drives the cylinder 311 to move laterally. When the cylinder 311 moves laterally, it drives the round tube 313 to move laterally through the first bearing ring 312. When the round tube 313 moves laterally, it drives the grinding part 13 to move laterally through the adjustment part 32, thereby adjusting the lateral position of the grinding part 13. When the grinding head of the grinding section 13 moves into the inside of the ear sleeve, the adjusting screw 323 is rotated. When the adjusting screw 323 rotates, it drives the grinding section 13 to move axially. When the grinding head of the grinding section 13 contacts the inner wall of the ear sleeve, the second drive motor 315 is activated. When the second drive motor 315 runs, it can drive the gear 316 to rotate. The rotation of the gear 316 drives the round tube 313 to rotate through the gear ring 314. When the round tube 313 rotates, it can drive the grinding section 13 to rotate through the adjusting section 32, so that a full circle of grinding can be performed inside the ear sleeve. At the same time, the extension of the telescopic rod 42 drives the cylinder 311 to move laterally, and the first bearing ring 312 drives the round tube 313 to move laterally. In this way, the round tube 313 drives the grinding part 13 to move laterally, thereby adjusting the depth of the grinding head of the grinding part 13 inside the ear sleeve, so as to grind the inner wall of the far end of the ear sleeve.

[0033] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
