[0002] Track shoes are one of the chassis parts of construction machinery and are a kind of vulnerable parts of the construction machinery used. They are now commonly used in construction machinery such as excavators, bulldozers, crawler cranes, and pavers. There are many processes in the processing of track shoes, including cutting, punching, painting, welding, etc.

[0003] After the track shoe is punched, there are some burrs on the edge of the hole on the punching end surface of the track shoe. These burrs need to be cleaned. When cleaning, the track shoe needs to be turned over first, and then the burrs on the edge of the hole are scraped off with a tool. The scraped burrs are attached to the track shoe, and the scraped burrs need to be cleaned again. The track shoe can be removed only after the scraped burrs are cleaned, and then it is moved to the next process for processing. In this process, turning over, scraping burrs, and cleaning burrs after punching are all performed separately, resulting in a lack of continuity in the processing process.

[0014] The present invention also provides a track shoe flipping method, which uses the above flipping device and includes the following steps: Step 1: Place the track shoe on the lower template, move the track shoe to embed it into the concave clamping plate, and then rotate the screw rod so that the pressure plate presses the track shoe tightly into the concave clamping plate; Step 2: The hydraulic cylinder extends and drives the upper template to move downward, so that the upper template punches the track shoe. When the upper template moves downward, it drives the connecting rod downward. When the connecting rod moves downward, it slides in the vertical groove 1, the inclined groove, and the vertical groove 2. When the connecting rod slides in the inclined groove, it squeezes the tooth plate to drive the tooth plate to move away from the stroke groove 2. At this time, the one-way bearing is not locked, and the tooth plate drives the gear and the outer ring of the one-way bearing to rotate, while the inner ring of the one-way bearing and the rotating rod do not rotate. That is, the track shoe is always located on the lower template and directly below the upper template during this process, so that the upper template can be punched after it moves downward; Step 3: After the track shoe is punched, the hydraulic cylinder contracts and drives the upper template to move upward, and the connecting rod moves upward in the second vertical groove. At this time, the tooth plate does not move. When the connecting rod moves into the inclined groove, the tooth plate is squeezed to drive the tooth plate to move toward the second stroke groove. At this time, the one-way bearing is locked. The movement of the tooth plate will drive the gear, the one-way bearing, and the rotating rod to rotate synchronously, thereby driving the track shoe to flip. When the connecting rod moves from the inclined groove to the first vertical groove, the track shoe after punching is flipped 180°, so that the end face of the track shoe punching faces upward, and the track shoe is placed on the pad; Step 4: When the track shoe is flipped, the hydraulic cylinder continues to contract and drives the upper template to move upward, so that the connecting rod moves upward in the vertical groove 1 and the travel groove 1. At this time, the connecting rod slides in the slide groove 1 to drive the rotating plate to rotate. When the rotating plate rotates, the slide groove 2 squeezes the L-shaped rod, that is, the L-shaped rod slides in the slide groove 2, and the L-shaped rod moves down in the travel groove 2, thereby driving the moving plate to move downward; Step 5: When the moving plate moves downward, it drives the cylinder and the cylindrical rod downward, so that the cylindrical rod extends into the punched hole in the track shoe, and the scraper is located on the edge of the hole. Then the moving plate continues to move downward, so that the cylindrical rod moves into the cylinder, and the convex column slides in the curved groove, thereby driving the cylindrical rod to rotate, so that the scraper scrapes off the burrs on the edge of the hole; Step 6: When the moving plate moves downward, the piston rod first contacts the track plate, causing the piston rod to move upward and drive the piston to move upward. When the piston moves upward, negative pressure is drawn into the lower chamber. At this time, under the action of atmospheric pressure, the sealing plate 1 rotates toward the direction of the air cylinder, so that the outside air is input into the air cylinder through the air intake pipe. When the piston moves upward, the spring 2 is compressed. At this time, the sealing plate 2 covers the triangular exhaust pipe opening; Step seven: After the scraper has scraped off the burrs on the edge of the hole, the hydraulic cylinder extends and drives the movable plate to move up. When the movable plate moves up, it drives the piston to move down under the elastic force of spring 2, so that the piston discharges the air in the lower chamber. At this time, sealing plate 1 is blocked by the baffle plate, so that sealing plate 1 blocks the air intake pipe, that is, the air in the lower chamber is discharged into the hollow plate through the connecting pipe, and then discharged from the hollow plate to the triangular exhaust pipe, so that the air blows sealing plate 2 so that sealing plate 2 no longer seals the opening of the triangular exhaust pipe, that is, the air is discharged from the triangular exhaust pipe and blows onto the track plate, blowing off the burrs scraped off the track plate.

[0015] It can be seen from the above technical solutions that the present application has the following beneficial effects: 1: After the track shoe is punched, the upper template moves up in the second vertical groove first. At this time, the tooth plate does not move. When the connecting rod moves in the inclined groove, it will squeeze the tooth plate and drive the tooth plate to move toward the direction of the second stroke groove. At this time, the one-way bearing is locked, and the movement of the tooth plate will drive the gear, the one-way bearing, and the rotating rod to rotate synchronously, thereby flipping the track shoe, so that the end surface of the track shoe punching is flipped upward, thereby facilitating the subsequent cleaning of burrs on the edge of the hole. The second vertical groove set in this process enables the connecting rod to move a distance in the second vertical groove first when the upper template moves up. The track shoe does not flip during the distance the connecting rod moves in the second vertical groove. When the connecting rod moves into the inclined groove, the track shoe flips. At this time, the upper template has been away from the track shoe for a distance, so as to avoid the upper template from blocking the flipping of the track shoe when the track shoe is flipped later.

[0016] 2: When the movable plate moves downward, it drives the cylindrical rod to extend into the punched hole in the track shoe. At this time, the scraper is located on the edge of the hole. When the movable plate continues to move downward, the cylindrical rod moves into the cylinder, and the convex column slides in the curved groove, thereby driving the cylindrical rod to rotate, so that the scraper scrapes off the burrs on the edge of the hole.

[0017] 3: When the moving plate moves up, the piston is driven downward by the elastic force of spring 2, so that the piston discharges the air in the lower chamber. At this time, sealing plate 1 blocks the air intake pipe, and the air in the lower chamber is discharged into the hollow plate through the connecting pipe, and then discharged from the hollow plate into the triangular exhaust pipe, so that the air blows sealing plate 2, so that sealing plate 2 no longer seals the opening of the triangular exhaust pipe, that is, the air is discharged from the triangular exhaust pipe and blows onto the track plate, blowing off the burrs scraped off the track plate.

[0022] Reference Figure 1-8 : Example

[0023] A track shoe flipping device includes a punching unit 100 and a burr processing unit 200. The punching unit 100 includes a processing table 101. A vertical plate 102 is fixed on the processing table 101. A top plate 103 is fixed on the top of the vertical plate 102. A hydraulic cylinder 104 is installed at the bottom of the top plate 103. An upper template 105 is fixed at the extended end of the hydraulic cylinder 104. A rectangular groove 106 is opened in the processing table 101. A lower template 107 is fixed in the rectangular groove 106. A rotating rod 108 is rotatably connected in the processing table 101. An inner concave clamping plate 109 is fixed on the outer side of the rotating rod 108. A track shoe 110 is arranged in the inner concave clamping plate 109. A pad 111 is fixed in the rectangular groove 106. The track shoe 110 can be placed on the lower template 107. and the pad 111, a flipping assembly for flipping the track shoe 110 is arranged on one side of the vertical plate 102, and the burr processing unit 200 includes a movable plate 201, a plurality of cylinders 202 are fixed at the bottom of the movable plate 201, a cylindrical rod 203 is slidably connected inside the cylinder 202, and a plurality of scrapers 204 are fixed at equal intervals along the radial direction on the outer side of the cylindrical rod 203, a lifting assembly for controlling the lifting of the movable plate 201 is arranged on one side of the vertical plate 102, and the scraper 204 scrapes off the burrs on the edge of the hole after punching the track shoe when the movable plate 201 descends, and a cleaning assembly for cleaning the scraped burrs from the track shoe is arranged at the bottom of the movable plate 201, and the cleaning assembly is driven to work when the movable plate 201 is lifted and lowered.

[0024] Among them, the inner thread of the concave clamping plate 109 is connected with a screw rod 113, and a pressure plate 112 is fixed at the bottom of the screw rod 113. The pressure plate 112 clamps the track shoe 110 in the concave clamping plate 109. A stroke groove 114 and a stroke groove 2 127 are opened in the vertical plate 102. A connecting rod 115 is fixed on one side of the upper template 105, and the connecting rod 115 slides in the stroke groove 114. An L-shaped rod 128 is fixed on one side of the movable plate 201, and the L-shaped rod 128 slides in the stroke groove 2 127. The flip assembly includes a tooth plate 116, and a one-way bearing 129 is fixed on the outer side of the rotating rod 108 extending to the outer end of the processing table 101. A gear 120 is fixed on the outer ring of the one-way bearing 129. The tooth plate 116 and the gear 120 are meshed. When the tooth plate 116 moves away from the stroke groove 2 127, the one-way bearing 129 is not locked, and the tooth plate 116 is provided with a tooth plate 116. The movable gear 120 and the outer ring of the one-way bearing 129 rotate, the inner ring of the one-way bearing 129 and the rotating rod 108 do not rotate, and the one-way bearing 129 is locked when the tooth plate 116 moves toward the direction close to the stroke groove 2 127. The movement of the tooth plate 116 will drive the gear 120, the one-way bearing 129, and the rotating rod 108 to rotate synchronously, thereby driving the track shoe 110 to flip. A vertical groove 117, an inclined groove 118, and a vertical groove 2 119 are provided in the tooth plate 116. The two ends of the inclined groove 118 are respectively connected to the vertical groove 117 and the vertical groove 2 119. The connecting rod 115 is slidably matched in the vertical groove 117, the inclined groove 118, and the vertical groove 2 119. Two rectangular plates 121 are fixed on the back of the vertical plate 102. Two guide rods 122 are fixed between the two rectangular plates 121. The guide rods 122 penetrate the tooth plate 116, and the tooth plate 116 is slidably matched outside the guide rods 122.

[0025] When in use, the upper template 105 moves downward to punch the track shoe 110. When the upper template 105 moves downward, it drives the connecting rod 115 to slide in the vertical groove 117, the inclined groove 118, and the vertical groove 2 119. When the connecting rod 115 slides in the inclined groove 118, it squeezes the tooth plate 116 and drives the tooth plate 116 to move away from the stroke groove 2 127. At this time, the one-way bearing 129 is not locked, and the tooth plate 116 drives the gear 120 and the one-way bearing 129 when moving. The outer ring rotates, and the inner ring of the one-way bearing 129 and the rotating rod 108 do not rotate, that is, the movement of the toothed plate 116 in this process only drives the gear 120 and the outer ring of the one-way bearing 129 to rotate, and the inner ring of the one-way bearing 129 and the rotating rod 108 do not rotate, so that the track shoe 110 will not flip over in this process, that is, the track shoe 110 is always located on the lower template 107 and directly below the upper template 105 in this process, and punching can be performed when the upper template 105 moves down.

[0026] It should be noted that after the track shoe 110 is punched, the hydraulic cylinder 104 contracts and drives the upper template 105 to move upward, and the connecting rod 115 moves upward in the second vertical groove 119. At this time, the connecting rod 115 does not squeeze the tooth plate 116, so that the tooth plate 116 does not move. When the connecting rod 115 moves from the second vertical groove 119 to the inclined groove 118, the connecting rod 115 squeezes the tooth plate 116 in the inclined groove 118 and drives the tooth plate 116 to move toward the direction close to the second stroke groove 127. At this time, the one-way bearing 129 is locked, and the movement of the toothed plate 116 will drive the gear 120, the one-way bearing 129, and the rotating rod 108 to rotate synchronously, thereby driving the track shoe 110 to flip. The second vertical groove 119 provided in this process enables the connecting rod 115 to move a certain distance in the second vertical groove 119 when the upper template 105 moves upward. The track shoe 110 does not flip during the distance that the connecting rod 115 moves in the second vertical groove 119. The track shoe 110 is turned over only when the connecting rod 115 moves from the inclined groove 118 to the vertical groove 117. At this time, the upper template 105 has been away from the track shoe 110 for a distance, so as to prevent the upper template 105 from blocking the turning of the track shoe 110 when the track shoe 110 turns over. When the connecting rod 115 moves from the inclined groove 118 to the vertical groove 117, the track shoe 110 has been turned over. At this time, the bottom of the piston rod 216 has not yet contacted the track shoe 110. 7 will drive the movable plate 201 to continue to move downward, and the burrs will be processed. In this process, when the connecting rod 115 moves from the inclined groove 118 to the vertical groove 117, the track shoe 110 after punching is automatically flipped 180°, so that the punching end surface of the track shoe 110 faces upward, and the track shoe 110 is placed on the pad 111. At this time, the punching end surface of the track shoe 110 is flipped to face upward, so as to facilitate the subsequent cleaning of the burrs on the edge of the hole.

[0027] In addition, the lifting assembly includes a central column 123 fixed to the back of the vertical plate 102, and the outer side of the central column 123 is rotatably connected to a rotating plate 124, and a slide groove 125 and a slide groove 2 126 are provided in the rotating plate 124, the connecting rod 115 slides in the slide groove 125, the L-shaped rod 128 slides in the slide groove 2 126, a curved groove 205 is provided in the cylinder 202, a convex column 206 is fixed to the outer side of the cylindrical rod 203, and the convex column 206 slides in the curved groove 205, and a spring 1 208 is arranged in the cylinder 202, and the two ends of the spring 1 208 are respectively against the inner wall of the cylinder 202 and the top of the convex column 206.

[0028] In addition, the cleaning assembly includes an air cylinder 209 fixed in the movable plate 201, a sealing plug 215 is fixed at the bottom of the air cylinder 209, a piston rod 216 is sealingly slidably disposed in the sealing plug 215, a piston 214 is fixed at the top of the piston rod 216, the piston 214 seals and slides in the air cylinder 209, and the piston 214 divides the air cylinder 209 into a lower chamber 224 and an upper chamber 225, two connecting plates 223 are fixed at the bottom of the movable plate 201, a hollow plate 210 is fixed at the bottom of the connecting plate 223, a connecting pipe 211 is fixed on the hollow plate 210 and is connected to the hollow plate 210, one end of the connecting pipe 211 away from the hollow plate 210 is fixed to the air cylinder 209 and is connected to the lower chamber 224, and the hollow plate 210 Triangular exhaust pipes 212 are fixed and connected on both sides, an intake pipe 213 is fixed at the bottom of the air cylinder 209 and the intake pipe 213 is connected to the lower chamber 224, a sealing plate 219 is rotatably connected inside the intake pipe 213, a baffle 220 for blocking the sealing plate 219 is fixed to the inner wall at the bottom of the intake pipe 213, two protrusions 221 are fixed on one side of the triangular exhaust pipe 212, a sealing plate 222 for sealing the opening of the triangular exhaust pipe 212 is rotatably connected between the two protrusions 221, a plurality of air holes 218 are opened on the top of the air cylinder 209, a spring 217 is arranged inside the air cylinder 209, and the two ends of the spring 217 are respectively against the inner wall of the air cylinder 209 and the piston 214.

[0029] When in use, when the movable plate 201 moves downward, the piston rod 216 first contacts the track shoe 110, so that the piston rod 216 moves upward and drives the piston 214 to move upward. When the piston 214 moves upward, the air in the upper chamber 225 is discharged from the air hole 218, and the piston 214 will compress the spring 217, and when the piston 214 moves upward, the lower chamber 224 is evacuated into a negative pressure. At this time, under the action of atmospheric pressure, the sealing plate 1 219 rotates toward the direction close to the air cylinder 209, so that the outside air is input into the air cylinder 209 through the air inlet pipe 213. At this time, the sealing plate 222 blocks the opening of the triangular exhaust pipe 212. When the movable plate 201 moves downward and drives the cylindrical rod 203 to extend into the hole punched in the track shoe 110, the scraper 204 is located on the edge of the hole. When the movable plate 201 continues to move downward, the cylindrical rod 203 moves into the cylinder 202, and the protruding column 206 is in the curved groove 20 5, thereby driving the cylindrical rod 203 to rotate, so that the scraper 204 scrapes the burrs on the edge of the hole. After the scraper 204 scrapes the burrs on the edge of the hole, the movable plate 201 moves up, and drives the piston 214 to move down under the elastic force of the spring 217, so that the piston 214 discharges the air in the lower chamber 224. At this time, the sealing plate 1 219 is in a vertical state under the action of gravity and is blocked by the baffle 220, so that the sealing plate 1 219 blocks the air inlet pipe 213. At this time, the air in the lower chamber 224 is discharged into the hollow plate 210 through the connecting pipe 211, and then discharged from the hollow plate 210 into the triangular exhaust pipe 212, so that the air blows the sealing plate 222, so that the sealing plate 222 no longer seals the opening of the triangular exhaust pipe 212, that is, the air is discharged from the triangular exhaust pipe 212 and blows onto the track shoe 110, so that the burrs scraped off the track shoe 110 are blown off the track shoe 110. Example

[0030] A track shoe flipping method, based on the first embodiment, comprises the following steps: Step 1: Place the track shoe 110 on the lower template 107, move the track shoe 110 to embed it into the concave clamping plate 109, and then rotate the screw 113 so that the pressure plate 112 presses the track shoe 110 tightly against the concave clamping plate 109; Step 2: The hydraulic cylinder 104 extends and drives the upper template 105 to move downward, so that the upper template 105 punches the track shoe 110. When the upper template 105 moves downward, it drives the connecting rod 115 to move downward. When the connecting rod 115 moves downward, it slides in the vertical groove 117, the inclined groove 118, and the vertical groove 2 119. When the connecting rod 115 slides in the inclined groove 118, the tooth plate 116 is squeezed to drive the tooth plate 116 to move away from the stroke groove 2 127. At this time, the one-way bearing 129 is not locked, and the tooth plate 116 drives the gear 120 and the outer ring of the one-way bearing 129 to rotate, and the inner ring of the one-way bearing 129 and the rotating rod 108 do not rotate, that is, the track shoe 110 is always located on the lower template 107 and directly below the upper template 105 during this process, so that the upper template 105 can be punched after moving downward; Step 3: After the track shoe 110 is punched, the hydraulic cylinder 104 contracts and drives the upper template 105 to move upward, and the connecting rod 115 moves upward in the vertical groove 119. At this time, the tooth plate 116 does not move. When the connecting rod 115 moves into the inclined groove 118, the tooth plate 116 is squeezed to drive the tooth plate 116 to move toward the direction of the stroke groove 127. At this time, the one-way bearing 129 is locked. The movement of the tooth plate 116 will drive the gear 120, the one-way bearing 129, and the rotating rod 108 to rotate synchronously, thereby driving the track shoe 110 to flip. When the connecting rod 115 moves from the inclined groove 118 to the vertical groove 117, the track shoe 110 after punching is flipped 180°, so that the punching end surface of the track shoe 110 faces upward, and the track shoe 110 is placed on the pad 111; Step 4: When the track shoe 110 is turned over, the hydraulic cylinder 104 continues to contract and drives the upper template 105 to move upward, so that the connecting rod 115 moves upward in the vertical groove 117 and the travel groove 114. At this time, the connecting rod 115 slides in the slide groove 125 and drives the rotating plate 124 to rotate. When the rotating plate 124 rotates, the slide groove 126 squeezes the L-shaped rod 128, that is, the L-shaped rod 128 slides in the slide groove 126, and the L-shaped rod 128 moves downward in the travel groove 127, thereby driving the moving plate 201 to move downward; Step 5: When the moving plate 201 moves downward, it drives the cylinder 202 and the cylindrical rod 203 downward, so that the cylindrical rod 203 extends into the hole punched in the track shoe 110, and the scraper 204 is located on the edge of the hole. Then, the moving plate 201 continues to move downward, so that the cylindrical rod 203 moves into the cylinder 202, and the protruding column 206 slides in the curved groove 205, thereby driving the cylindrical rod 203 to rotate, so that the scraper 204 scrapes off the burrs on the edge of the hole; Step 6: When the moving plate 201 moves downward, the piston rod 216 first contacts the track shoe 110, so that the piston rod 216 moves upward and drives the piston 214 to move upward. When the piston 214 moves upward, the lower chamber 224 is evacuated to a negative pressure. At this time, under the action of atmospheric pressure, the sealing plate 1 219 rotates toward the air cylinder 209, so that the outside air is input into the air cylinder 209 through the air inlet pipe 213. When the piston 214 moves upward, the spring 217 is compressed. At this time, the sealing plate 222 blocks the opening of the triangular exhaust pipe 212. Step seven: after the scraper 204 scrapes off the burrs on the edge of the hole, the hydraulic cylinder 104 extends and drives the movable plate 201 to move upward. When the movable plate 201 moves upward, it drives the piston 214 to move downward under the elastic force of the spring 217, so that the piston 214 discharges the air in the lower chamber 224. At this time, the sealing plate 1 219 is blocked by the baffle 220, so that the sealing plate 1 219 blocks the air intake pipe 213, that is, the air in the lower chamber 224 is discharged into the hollow plate 210 through the connecting pipe 211, and then discharged from the hollow plate 210 into the triangular exhaust pipe 212, so that the air blows the sealing plate 222 so that the sealing plate 222 no longer seals the opening of the triangular exhaust pipe 212, that is, the air is discharged from the triangular exhaust pipe 212 and blows onto the track shoe 110, so that the burrs scraped off the track shoe 110 are blown off the track shoe 110.
