Description

Technical Field

[0001] The invention relates to the technical field of machining equipment, in particular to automatic grinding equipment for laser cladding and finishing of a middle groove. Background Art

[0002] The middle trough is mainly used for scraper conveyors and transfer machines in coal mines. The middle trough is the body of the scraper conveyor, which is composed of the middle plate and trough sides. The upper trough is used to transport coal and the lower trough is used for the return of the scraper chain. In order to improve its service life, it is necessary to perform wear-resistant cladding treatment on the surface of the middle bottom plate in the middle trough to increase the hardness of the middle bottom plate surface, making it more wear-resistant, thereby extending the service life of the scraper conveyor, reducing the cost of use, and improving production efficiency. After the laser cladding treatment, the middle trough needs to undergo a series of subsequent treatments to meet the use standards, among which grinding is a particularly important processing procedure.

[0003] There are two ways to grind the middle groove after laser cladding: manual grinding and mechanical grinding. Manual grinding requires the staff to use handheld grinding equipment to grind the middle groove, while mechanical grinding uses special grinding equipment to grind the middle groove. The former is not only troublesome to operate, time-consuming and labor-intensive, but also has a large labor burden, and it is difficult to ensure the smoothness of the grinding, and it also poses a certain threat to the health of the staff. The latter can realize the automatic grinding of the middle groove. For example: a Chinese patent with an authorization announcement number of CN221849712U discloses a special device for grinding the surface of the bottom plate in the middle groove of a scraper conveyor. The special device for grinding the surface of the bottom plate in the middle groove of a scraper conveyor includes: a base, a moving mechanism is fixedly installed on the top of the base, and a lifting device is fixedly installed on the top of the moving mechanism.

[0004] The technical solution in the above patent document makes it difficult to collect and process the dust generated by grinding the product, and the grinding tool needs to move back and forth on the product to achieve efficient grinding of the product, affecting the processing efficiency of a large number of middle grooves. The grinding of the middle grooves is divided into two steps: coarse grinding and fine grinding. The above grinding equipment cannot achieve two-step synchronous grinding of the product, and the grinding tool needs to be replaced or the product needs to be transferred to a transfer station, further reducing the processing efficiency of the product. In addition, during the grinding process, the product needs to be manually sprinkled with the corresponding treatment liquid and cleaned after grinding, which increases the burden and work risks of the staff.

[0048] A rectangular through slot is provided at the rear end of the inner rod 162, and a driven wedge 164 is installed inside the rectangular through slot. The inclined surface of the driven wedge 164 is slidably connected to the active wedge 165, and an adjustment rod 166 is fixedly connected to the side wall of the active wedge 165. A T-shaped slide slot is provided on the inclined surface of the driven wedge 164, and a T-shaped slide bar adapted to the T-shaped slide slot is integrally provided on the inclined surface of the active wedge 165, thereby ensuring the stability of the sliding between the active wedge 165 and the driven wedge 164.

[0049] The side of the adjusting rod 166 is provided with a cam 167 located on the coarse grinding roller 8 and the fine grinding roller 9. An annular groove is provided on the peripheral wall of the cam 167, and a slider is slidably connected in the annular groove. The end of the adjusting rod 166 away from the active wedge block 165 is fixedly connected to the corresponding slider by a screw. When the cam 167 rotates, the reciprocating motion of the corresponding active wedge block 165 is realized through the corresponding adjusting rod 166, and then the corresponding inner rod 162 is driven to move through the driven wedge block 164, so as to realize the reciprocating wiping effect of the wiping member 168.

[0050] The outer shell wall of the tube body 161 is symmetrically provided with support plates, and the side of the support plates away from the tube body 161 is fixedly connected to the corresponding loading parts 52 by bolts. The structural form of the support plates is adjusted accordingly according to the actual requirements of the tube body 161 loading.

[0051] The working principle of the present invention is as follows: when the product is used, the inspection panel 32 in the housing 3 is first opened, and then the appropriate coarse grinding roller 8, fine grinding roller 9 and wiping member 168 in the wiping mechanism 16 are loaded according to the specifications of the product to be processed, and then the electric push rod group 4 is started through the control panel set on the housing 3, so that the carrier 5 is moved down and adjusted, and it stops running after reaching the appropriate height. The side fence mechanism 2 in the conveying component is adjusted according to the specifications of the product to be processed. By adjusting the screw rod 22, the corresponding guide plate 23 is linearly displaced under the action of the auxiliary rod 24, so as to realize the side guidance of the product to be processed. After the adjustment of the side fence mechanism 2 is completed, the inspection panel 32 is closed, and then the motor 1 13 in the conveying mechanism 1, the motor 2 101 in the driving assembly 10 in the processing component and the dust collection device body 63 in the dust collection mechanism 6 are started through the control panel.

[0052] When the motor 13 is running, it drives the corresponding transmission roller to move, and then the conveyor belt 14 drives the ejection assembly 15 loaded thereon to move. The operation of the motor 2 101 makes the toothed chain 102 move, and then the coarse grinding roller 8 and the fine grinding roller 9 move synchronously.

[0053] When the equipment is deployed, the product to be processed after laser cladding is placed on the conveying mechanism 1. When the conveying mechanism 1 is running, the push-up assembly 15 in the conveying mechanism 1 pushes the product to be processed placed thereon. After the conveying mechanism 1 pushes the product to be processed into the range of the processing component, it first enters the rough station and then the fine station. Finally, the product after rough and fine processing will leave the range of the processing component and be unloaded with the movement of the conveying mechanism 1.

[0054] When the product to be processed enters the rough station, the spray assembly 72 of the spray mechanism 7 in the rough station contacts the product first. As the product to be processed continues to move, the contact sleeve 726 in the spray assembly 72 rotates due to contact with the product to be processed. When the contact sleeve 726 rotates, the end plate 723, the arc shield plate 722 and the corresponding blocking plate 725 are driven to rotate synchronously through the moving rod 724. Among them, the arc shield plate 722 is misaligned with the dripping hole on the outer tube 721 during rotation, so that the corresponding treatment liquid is intermittently dripped onto the product to be processed as the contact sleeve 726 rotates.

[0055] The product to be processed moves continuously, and when it contacts the rough grinding roller 8, since the rotation direction of the rough grinding roller 8 is opposite to the moving direction of the product to be processed, the product to be processed is rough ground.

[0056] Most of the dust generated during the rough grinding of the product to be processed is restrained by the wind hood 62 in the dust collection mechanism 6, and then the dust is collected by the parallel air duct 61, the vertical air duct and the air duct under the operation of the dust collection device body 63.

[0057] The product that has been rough-ground moves continuously under the action of the conveying mechanism 1. When it contacts the wiping mechanism 16, the rotation of the rough-ground roller 8 drives the movement of the cam 167, which in turn causes the adjustment rod 166 to reciprocate, causing the active wedge 165 thereon to move synchronously. The active wedge 165 is slidably connected to the driven wedge 164, so that the inner rod 162 can be reciprocated in the tube body 161, so that the ear plate 163 drives the corresponding wiping member 168 to reciprocate in the horizontal direction, thereby wiping and cleaning the product that has been rough-ground.

[0058] The roughly polished product moves continuously with the conveying mechanism 1 into the fine work area, and then leaves the processing part and is unloaded with the operation of the conveying mechanism 1 after a polishing treatment similar to that in the rough work area, thereby realizing multi-step, continuous and efficient processing of the product.

[0059] Since each spraying assembly 72 is respectively located on the right side of the coarse grinding roller 8 and the fine grinding roller 9, the treatment liquid intermittently dripped onto the product by the spraying assembly 72 will adhere to the coarse grinding roller 8 and the fine grinding roller 9 after contacting them, thereby ensuring that the coarse grinding roller 8 and the fine grinding roller 9 grind the un-dripping areas on the product, and reducing resource consumption by intermittent dripping of the treatment liquid.

[0060] The above are only preferred specific implementation modes of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solutions and inventive concepts of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
