Description

Technical Field

[0001] The invention relates to the technical field of track wheel surface treatment devices, in particular to a roller type shot blasting cleaning device for track wheels. Background Art

[0002] Track rollers are key components of tracked chassis. Their primary function is to support weight, requiring them to withstand significant pressure and possess extremely high strength requirements. Therefore, during production and processing, track rollers are often treated with shot blasting machines. This treatment removes scale, grease, dirt, rust, and other contaminants from the track roller surface. Simultaneously, the high-speed stream of shot blasting sprays onto the workpiece, causing plastic deformation and forming a thick reinforcement layer. To facilitate assembly line processing of track rollers, roller-type shot blasting machines are often used for surface treatment.

[0003] The roller-type shot blasting machine uses a conveyor roller to transport the rollers to be surface-treated to the discharge port of the shot blasting machine's cleaning chamber. The treated rollers are then transported to the next processing station. The high-speed shot streams thrown by the efficient shot blasters strike the oxide scale, rust, and other debris on the surface of the axle blank, giving it a fine, bright surface and revealing the workpiece's true metallic color. This helps improve the axle's coating quality, achieving corrosion protection, pipe protection, and extending the service life of steel pipes. The roller-type shot blasting machine primarily consists of a cleaning chamber, conveyor rollers, shot blasters, a shot circulation system (including an elevator, separator, screw conveyor, and shot delivery pipeline), dust removal, and electrical control.

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] See also Figure 1-9 The present invention provides a technical solution, a roller-type shot blasting cleaning device for supporting wheels, comprising a shot blasting machine body 1, a feed conveyor roller 2 and a discharge conveyor roller 3, a transfer base 4 is arranged at a position opposite to the material taking and discharging window of the shot blasting machine body 1, and the feed conveyor roller 2 and the discharge conveyor roller 3 are respectively arranged on both sides of the transfer base 4.

[0036] The transfer base 4 includes a fixed base 41 fixed to the ground with anchor bolts and a rotating cylinder 42 rotatably connected to the top of the fixed base 41. The inner cavity of the fixed base 41 is provided with a servo motor whose power output shaft is fixedly sleeved with the center of the bottom surface of the rotating cylinder 42. The middle part of the bottom surface of the horizontal cylinder 43 is fixed to the top surface of the rotating cylinder 42. A cylindrical shell 44 is fixed on both sides of the middle part of the horizontal cylinder 43. A driving gear 46 and a guide gear 47 are rotatably installed in the inner cavity of the cylindrical shell 44. A translation motor 45 is fixed on the top surface of the cylindrical shell 44 corresponding to the guide gear 47. The power output shaft of the translation motor 45 is transmission-connected with the driving gear 46; the horizontal beam body 5 is slidably sleeved in the inner cavity of the horizontal cylinder body 43, and a groove 51 is axially provided in the middle of the front and back of the horizontal beam body 5, and a rack 52 is respectively provided in the groove 51, which is meshed with the driving gear 46 and the guide gear 47.

[0037] The rotating motor 6 is fixed to the top surfaces of the two ends of the horizontal beam 5, and the rotating base 7 is respectively arranged below the two ends of the horizontal beam 5. The rotating base 7 includes a turntable 71 on the power output shaft of the rotating motor 6 at the center of the top surface and a material claw telescopic cylinder 72 vertically fixed to the two ends of the bottom surface of the turntable 71. The bottom end of the telescopic rod of the material claw telescopic cylinder 72 is fixed to the support base 8.

[0038] The support base 8 includes a horizontal plate body 81 and an ear plate 82 fixed in the middle of both sides of the horizontal plate body 81 and fixedly connected to the bottom end of the telescopic rod of the material claw telescopic cylinder 72. The paired material claw assemblies 9 are slidably clamped on the same support base 8 in the horizontal direction, and a slide groove 83 is respectively provided at a position near one end of the top front of the horizontal plate body 81 and near the other end of the rear. The top surface of the horizontal plate body 81 is respectively fixed with a clamping telescopic cylinder 85 at a position corresponding to the end of the slide groove 83. The material claw assembly 9 includes a crossbeam 91 slidably clamped in the slide groove 83, a vertical plate 92 fixed vertically at both ends of the bottom surface of the crossbeam 91 and fixedly connected to one side of the top of the air intake chuck 93 and the exhaust chuck 94, and a connecting plate 97 fixed at one end of the top surface of the crossbeam 91 and connected to the end of the telescopic rod of the corresponding clamping telescopic cylinder 85. The clamping telescopic cylinder 85 pushes the corresponding material claw assembly 9 to slide so that the outer end surface of the air intake chuck 93 and the inner end surface of the exhaust chuck 94 are respectively clamped to the two end surfaces of the supporting wheel. When the two paired material claw assemblies 9 on a supporting base 8 are installed, the two material claw assemblies 9 correspond to the two end positions of the horizontal plate body 81 at one end of the exhaust chuck 94, and the corresponding ends of the air intake chuck 93 are respectively located below the middle of the horizontal plate body 81, and the two air intake chucks 93 are staggered. That is, the air intake chuck 93 of one material claw assembly 9 is located between the air intake chuck 93 and the exhaust chuck 94 of the other material claw assembly 9, and the center lines of the exhaust chuck 94 and the air intake chuck 93 on the two material claw assemblies 9 are on the same horizontal straight line. When the two clamping telescopic cylinders 85 are extended at the same time, the two material claw assemblies 9 as a whole move toward the middle direction of the horizontal plate body 81 at the same time, so that the exhaust chuck 94 of one material claw assembly 9 and the air intake chuck 93 of the other material claw assembly 9 clamp the same supporting wheel, so as to ensure that the two ends of the central hole cavity of the supporting wheel are aligned with the purge hole 98 and the slag discharge hole 99 respectively.

[0039] The outer end face of the air intake chuck 93 is provided with a purge hole 98, and the inner end face of the air exhaust chuck 94 is provided with a slag discharge hole 99. The top surface of the crossbeam 91 is vertically opened with an air intake channel 95 corresponding to the position of the air intake chuck 93, and the bottom end is connected to the inner end of the purge hole 98. The air intake channel 95 is connected to the output end of the air pump through a pipeline. The outer end face of the exhaust chuck 94 is provided with an exhaust pipe 96 whose inner cavity is connected to the slag discharge hole 99. The exhaust pipe 96 is connected to the dust removal equipment through a pipeline.

[0040] In order to further ensure the stability of the horizontal sliding of the claw assembly 9 along the support base 8, the top surface of the horizontal plate body 81 is provided with a card slot 84 on both sides of the slide groove 83, which is slidably engaged with the end of the connecting plate 97.

[0041] In order to realize the automation and convenience of opening and closing the material taking and discharging window of the shot blasting machine body 1, the following method can be specifically adopted: a door panel 11 for closing the material taking and discharging window is slidably mounted in the vertical direction at the material taking and discharging window of the shot blasting machine body 1, and a door panel telescopic cylinder 12 is vertically installed at the position above the material taking and discharging window of the shot blasting machine body 1, and the bottom end of the telescopic rod of the door panel telescopic cylinder 12 is fixedly connected to the top end of the door panel 11.

[0042] In summary, the feed conveyor roller 2 is responsible for transporting the supporting rollers to be surface treated to the unloading position. When the feed conveyor roller 2 transfers the supporting rollers, it transports them in groups of two side by side; through the rotation of the rotating cylinder 42 and the horizontal driving action of the translation motor 45 on the horizontal beam 5 through the gear rack transmission, the material claw assembly 9 at one end of the horizontal beam 5 is transferred to directly above the two supporting rollers to be processed; through the rotation action of the rotating motor 6 on the turntable 71, the air intake chuck 93 and the exhaust chuck 94 are respectively opposite to the two side positions of the two supporting rollers at the unloading position; the material claw telescopic cylinder 72 is extended, so that the air intake chuck 93 and the exhaust chuck 94 respectively fall to the position facing the two end faces of the corresponding supporting rollers; then the clamping telescopic cylinder 85 is extended, so that the air intake chuck 93 and the exhaust chuck 94 complete the clamping action on the supporting rollers; then the material claw telescopic cylinder 72 contracts, so that the supporting rollers are separated from the feed conveyor roller 2.

[0043] The door panel telescopic cylinder 12 extends, causing the door panel 11 to fall, opening the material loading and unloading window of the shot blasting machine body 1. With the rotation of the rotating cylinder 42 and the horizontal drive of the horizontal beam 5 by the translation motor 45 through the gear rack transmission, one end of the horizontal beam 5 is made to penetrate into the material loading and unloading window, the claw telescopic cylinder 72 extends, and the clamping telescopic cylinder 85 contracts, so that the supporting roller to be processed is placed in the shot blasting cleaning station in the material loading and unloading window; the end of the horizontal beam 5 withdraws from the material loading and unloading window, and the door panel telescopic cylinder 12 contracts, causing the door panel 11 to rise to close the material loading and unloading window. At this time, the shot blasting cleaning equipment of the shot blasting machine body 1 is turned on to carry out the surface treatment process of the supporting roller.

[0044] After the surface treatment process of the supporting roller is completed, the material loading and unloading window is opened to complete the grabbing process of the supporting roller. Before placing the supporting roller on the discharge conveyor roller 3, the air pump is turned on, and high-pressure air is discharged from the air inlet channel 95 and the purge hole 98 through the pipeline to purge the central hole cavity of the supporting roller. The purged dust is transported to the dust removal equipment through the slag discharge hole 99 and the exhaust pipe 96 to complete the cleaning of the central hole cavity of the supporting roller and the collection process of the purged dust. Finally, the cleaned supporting roller is placed on the discharge conveyor roller 3 to be transported to the next processing station.
