Description

Technical Field

[0001] The invention relates to the technical field of pick processing, in particular to a pick processing fixture for a bolter digger used in coal mines. Background Art

[0002] In coal mining operations, bolter miners are key equipment and their picks are core components that directly participate in rock breaking. The performance of the picks will directly affect mining efficiency and safety. Figure 7 As shown, the pick includes a tooth body and an alloy cutter head. The lower part of the tooth body is cylindrical, the upper part of the tooth body is conical, and a shoulder is provided at the connection between the cylindrical and conical parts of the tooth body. A connecting hole is provided at the top of the conical part of the tooth body. The operator places the alloy cutter head in the connecting hole of the tooth body and welds the alloy cutter head and the tooth body. Brazing is commonly used in the existing welding method. By filling the brazing material in the part to be welded, the high-frequency electromagnetic field is used to heat the carbide cutter head, tooth body and brazing material, and the brazing material is melted to achieve the welding of the alloy cutter head and the tooth body. After welding, the pick is quenched and processed.

[0003] During the specific welding process, the existing fixture supports the lower side of the shoulder of the tooth body through multiple clamping rods and clamps the cylindrical part of the tooth body. Then the operator places the alloy cutter head in the connecting hole of the tooth body and fills the brazing material in the part that needs to be welded. Then, the tooth body and the alloy cutter head are transported to the induction heating system by the conveying equipment, and the fixture is started to drive the tooth body to rotate, so that the induction heating system evenly heats the carbide cutter head, tooth body and brazing material to complete the welding and forming of the pick. Finally, the conveying equipment transports the formed pick to the subsequent processing station.

[0004] However, the following problems exist in the above-mentioned welding process: 1. When it is necessary to form picks of different sizes and specifications, the existing fixture cannot adjust the height position of the clamped tooth body, resulting in changes in the distance between the connecting holes of the tooth bodies of different sizes and specifications and the induction coil, which affects the heating effect and thus affects the welding forming quality of the pick; 2. When the brazing material is filled between the alloy cutter head and the tooth body, there may be a problem of uneven distribution of the brazing material between the alloy cutter head and the tooth body, which will in turn reduce the welding forming quality of the pick; 3. During the heating process, the cylindrical part of the tooth body corresponding to the clamping position of the fixture cannot be fully heated, which leads to uneven heating of the surface of the cylindrical part of the tooth body, affecting the subsequent forming quality of the pick. Summary of the Invention

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: a coal mine anchor cutting machine cutting tool processing fixture, including a processing seat and a chain conveyor installed thereon, the chain conveyor includes a plurality of chain plates, a clamping unit is installed on the chain plate, and an adjustment matching unit is connected between the clamping unit and the corresponding chain plate; the clamping unit includes a driving group installed on the chain plate, a plurality of circumferentially evenly arranged clamping rods are installed on the driving group, and a clamping group is installed on the upper side of the clamping rod, and the clamping group clamps the tooth body and drives the tooth body to rotate through the driving group; the adjustment matching unit includes an adjusting plate arranged above the chain plate, and the positions of the corresponding clamping rods on the adjusting plate all slide radially A movable slider is installed, which is rotatably connected to the corresponding clamping rod.

When the clamping group drives the tooth body to rotate, the shaking group and the adjustment plate cooperate to shake the tooth body up and down through the clamping group to ensure that the solder is evenly filled in the welding place. At the same time, the clamping rod is driven by the toggle group to rotate based on its own central axis, so that the clamping position of the clamping group on the tooth body continues to change.

[0012] Preferably, the shifting group includes a matching sleeve movably mounted on the outside of the clamping rod, and the clamping rod passes through the matching sleeve.

[0017] 3. The present invention drives the clamping rod to rotate with its own central axis as the reference by setting a toggle group, so that the clamping group causes the tooth body to rotate relative to the clamping rod through friction, and then realizes the continuous change of the clamping position of the clamping group on the tooth body, preventing the continuous clamping of a single position of the tooth body, which causes the tooth body surface to be unevenly heated, thereby ensuring the processing quality of subsequent cutting teeth.

[0027] The embodiments described below are exemplary and are only used to explain the present invention, and are not to be construed as limiting the present invention. If no specific techniques or conditions are specified in the embodiments, the techniques or conditions described in the literature in the art or the product instructions shall be followed.

[0028] See Figure 1 and Figure 6 A coal mine anchor cutting machine cutting tool processing fixture includes a processing seat 1, a chain conveyor 2 is installed on the processing seat 1, the chain conveyor 2 includes a plurality of chain plates 21, a clamping unit 3 is installed on the chain plate 21, and an adjustment and matching unit 4 is connected between the clamping unit 3 and the corresponding chain plate 21.

[0029] The present invention is used for clamping cutting teeth. The present invention can adjust the height position of the clamped tooth body. When forming cutting teeth of different sizes, it ensures that the distance between the connecting hole of the tooth body and the induction coil does not change, thereby ensuring the welding forming quality of the cutting teeth. At the same time, the present invention can shake the tooth body up and down to ensure that the brazing material is evenly filled between the alloy cutter head and the tooth body, further ensuring the welding forming quality of the cutting teeth. The present invention ensures that the surface of the cylindrical part of the tooth body is evenly heated by continuously changing the clamping position of the cylindrical part of the tooth body, thereby improving the forming quality of the cutting teeth and ensuring the consistency of batch cutting teeth forming.

[0030] Specifically, the operator first places the tooth body in the clamping unit 3 on the right side of the chain conveyor 2, and places the alloy cutter head and the brazing material on the tooth body. Then the operator controls the adjustment unit 4 to adjust the height position of the tooth body clamped by the clamping unit 3 according to the size specifications of the tooth body, starts the chain conveyor 2 to drive the clamping unit 3 and the clamped tooth body to move intermittently to the left, and the tooth body intermittently moves to the left into the existing induction heating system (the induction heating system is a prior art, and its specific structure is not described here and is not shown in the figure), and controls the movement to the corresponding position in the induction heating system. The clamping unit 3 drives the corresponding tooth body to rotate, so that the induction heating system heats the alloy cutter head and the tooth body evenly. At the same time, the adjusting and matching unit 4 drives the alloy cutter head and the tooth body to shake up and down through the clamping unit 3 to ensure that the brazing material is evenly filled between the alloy cutter head and the tooth body. The adjusting and matching unit 4 can continuously change the clamping position of the clamping unit 3 on the tooth body, so that the surface of the tooth body is evenly heated. Finally, when the chain conveyor 2 drives the welded pick to move intermittently to the left to the extreme position, the clamping unit 3 is controlled to release the clamping, and the chain conveyor 2 continues to transport the welded tooth body to the subsequent processing station.

[0031] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The clamping unit 3 includes a driving group 31 installed on the chain plate 21, and a plurality of circumferentially evenly arranged clamping rods 32 are installed on the driving group 31. A clamping group 33 is installed on the upper side of the clamping rod 32. The driving group 31 drives the clamping group 33 to clamp the tooth body through the clamping rod 32, and the driving group 31 also drives the tooth body to rotate through the clamping group 33.

[0032] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6The adjustment and matching unit 4 includes an adjustment plate 41 arranged above the chain plate 21. The positions of the adjustment plate 41 corresponding to the clamping rod 32 are radially slidably installed with a giving slider 42, and the giving slider 42 is rotatably connected to the corresponding clamping rod 32. A height adjustment group 43 is connected between the adjustment plate 41 and the chain plate 21. The height adjustment group 43 adjusts the height of the tooth connecting block clamped by the clamping group 33 through the adjustment plate 41; a shaking group 44 is connected between the height adjustment group 43 and the adjustment plate 41, and a toggle group 45 is connected between the height adjustment group 43 and the clamping rod 32.

[0033] The clamping unit 3 is used to clamp the tooth body, and the adjustment and matching unit 4 is used to cooperate with the clamping unit 3 to adjust the height of the clamped tooth body; specifically, the operator places the tooth body between multiple clamping groups 33, the clamping group 33 supports the lower side of the tooth body shoulder, and there is a certain distance between the lower end surface of the tooth body and the adjustment plate 41. When the induction coil heats the tooth body, the adjustment plate 41 is located below the induction coil, so that only the clamping group 33 is located in the heating area of ​​the induction coil at this time, and then the driving group 31 is controlled to drive the clamping rod 32 to move inward synchronously, and the clamping rod 32 drives the clamping group 33 to move inward synchronously to clamp the tooth body. The clamping rod 32 also drives the corresponding give-way slider 42 to move synchronously. Then, by controlling the height adjustment group 43, the adjustment plate 41 is driven to move up and down. The adjustment plate 41 drives the corresponding clamping rod 32 to move up and down through the give-way slider 42, thereby realizing height adjustment of multiple clamping rods 32, and then realizing adjustment of the height position of the tooth body clamped by the clamping group 33, ensuring that when forming picks of different sizes and specifications, the distance between the tooth body connection hole and the induction coil will not change, thereby ensuring the welding forming quality of the pick.

[0034] When the tooth body moves into the existing induction heating system, the corresponding driving group 31 is started to drive the clamping rod 32 to rotate with the central axis of the adjustment plate 41 as the reference, and the clamping rod 32 drives the clamped tooth body to rotate through the clamping group 33, so that the induction heating system heats the tooth body and the alloy cutter head evenly. At the same time, under the action of the shaking group 44, the clamping group 33 drives the clamped tooth body to shake up and down, so that the brazing material between the alloy cutter head and the tooth body is evenly distributed under the shaking action. At the same time, the toggle group 45 causes the clamping rod 32 to rotate with its own central axis as the reference, so that the clamping position of the clamping group 33 on the cutting tooth continues to change, so as to achieve uniform heating of the tooth body. When the cutting tooth welding is completed, the control driving group 31 drives multiple clamping rods 32 to move outward synchronously, so that the clamping rod 32 drives the clamping group 33 to release the cutting tooth.

[0035] See Figure 1 、 Figure 2 、 Figure 3 and Figure 4The driving group 31 includes an active part 311 installed on the chain plate 21, and a plurality of circumferentially evenly arranged transmission sleeves 312 are slidably installed on the active part 311. A sliding block 313 is slidably installed in the transmission sleeve 312. The upper end of the sliding block 313 is rotatably connected to the clamping rod 32, and the upper end of the clamping rod 32 passes through the transmission sleeve 312. A torsion spring is installed at the rotation connection between the clamping rod 32 and the sliding block 313.

[0036] It should be noted that the active part 311 in the present invention adopts the existing technology, which can drive multiple transmission sleeves 312 to move synchronously inward and outward, and then the transmission sleeves 312 drive multiple clamping rods 32 to move synchronously inward and outward, and the active part 311 can also ultimately drive the clamped tooth body to rotate with the center axis of the tooth body as the reference through the transmission sleeve 312.

[0037] The driving group 31 is used to drive the clamping group 33 to clamp the cutting teeth through the clamping rod 32. The driving group 31 is also used to drive the tooth body to rotate through the clamping group 33. Specifically, the starting active member 311 drives multiple transmission sleeves 312 to move inward synchronously, and the transmission sleeve 312 drives multiple clamping groups 33 to move inward synchronously and clamp the tooth body through the clamping rod 32. When the tooth body moves into the existing induction heating system, by starting the corresponding active member 311, all the transmission sleeves 312 are driven to rotate at a low speed with the central axis of the adjustment plate 41 as the reference. The transmission sleeve 312 drives the tooth body to rotate through the clamping rod 32 and the clamping group 33, so that the induction heating system evenly heats the tooth body and the alloy cutter head. When the cutting teeth are welded, the control active member 311 drives multiple transmission sleeves 312 to move outward synchronously, so that the clamping group 33 releases the clamped tooth body.

[0038] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The height adjustment group 43 includes an adjustment ring 431 distributed above the chain plate 21. An adjustment component is connected between the adjustment ring 431 and the corresponding chain plate 21. A connecting ring 432 is rotatably installed on the inner wall of the adjustment ring 431. The connecting ring 432 is connected to the adjustment plate 41 for sliding up and down through multiple elastic connecting rods 433 evenly arranged in the circumference; the elastic connecting rod 433 is provided with a large elastic force. When the clamping group 33 clamps the tooth body, the elastic connecting rod 433 will not be compressed under the action of the total gravity of the tooth body, the alloy cutter head and the solder.

[0039] See Figure 2 、 Figure 3 and Figure 6 The adjustment assembly includes a plurality of circumferentially arranged guide rods 434 that are slidably mounted on the adjustment ring 431, and the lower ends of the guide rods 434 are fixedly connected to the corresponding chain plates 21. An adjustment screw 435 is threadedly connected to the adjustment ring 431, and the adjustment screw 435 is rotatably connected to the chain plates 21.

[0040] The height adjustment group 43 is used to adjust the height position of the tooth body; specifically, screwing the adjustment screw 435 drives the adjustment ring 431 to move through threaded cooperation, and the adjustment ring 431 only moves up and down under the guide limit of the guide rod 434, and the adjustment ring 431 drives the adjustment plate 41 to move up and down through the connecting ring 432 and the elastic connecting rod 433, and the adjustment plate 41 drives the corresponding clamping rod 32 to move up and down through the giving way slider 42, so as to realize the synchronous adjustment of the height of multiple clamping rods 32, and then realize the adjustment of the height of the tooth body clamped by the clamping group 33, ensuring that when forming picks of different sizes, the distance between the connecting hole of the tooth body and the induction coil will not change, thereby ensuring the welding forming quality of the pick.

[0041] See Figure 1 、 Figure 2 、 Figure 3 and Figure 6 The shaking group 44 includes a plurality of circumferentially evenly arranged matching blocks 441 fixedly mounted on the upper side of the adjustment plate 41, and the upper end surface of the matching block 441 is set as a slope; the shaking group 44 also includes a plurality of circumferentially evenly arranged L-shaped downward pressure rods 442 fixedly mounted on the upper side of the adjustment ring 431. When the adjustment plate 41 rotates, the L-shaped downward pressure rod 442 and the inclined surface of the matching block 441 cooperate to drive the adjustment plate 41 to move downward.

[0042] The shaking group 44 is used to cooperate with the adjustment plate 41 to shake the tooth body up and down through the clamping group 33; specifically, when the corresponding active part 311 is started to drive all the transmission sleeves 312 to rotate as a whole with the central axis of the adjustment plate 41 as the reference, the transmission sleeve 312 drives the adjustment plate 41 to rotate through the clamping rod 32 and the give way slider 42, and the adjustment plate 41 drives the connecting ring 432 to rotate through the elastic connecting rod 433, and the adjustment plate 41 drives the matching block 441 to rotate, and the adjusting ring 431 is in a stationary state under the action of the guide rod 434. When the matching block 441 rotates to the corresponding position of the L-shaped lower pressure rod 442, the inclined surface of the matching block 441 and the horizontal section of the L-shaped lower pressure rod 442 cooperate to make the matching block 441 and the adjustment plate 41 as a whole Move downward slightly and compress the elastic connecting rod 433 slightly. When the horizontal sections of the matching block 441 and the L-shaped pressing rod 442 are separated, the adjustment plate 41 returns to its initial position under the action of the rebound force of the elastic connecting rod 433. The matching block 441 and the L-shaped pressing rod 442 are both provided with multiple pieces so that the adjustment plate 41 can continuously vibrate up and down. The adjustment plate 41 drives the clamping rod 32 to vibrate up and down through the giving way slider 42, so that the clamping rod 32 drives the clamped tooth body to vibrate up and down through the clamping group 33. The solder between the alloy cutter head and the tooth body is evenly distributed under the action of the shaking, and the clamping group 33 drives the clamped tooth body to vibrate up and down with a smaller amplitude and frequency, so that the alloy cutter head will not move out of the tooth body under the action of the shaking.

[0043] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 6 The clamping group 33 includes a clamping sleeve 331 concentrically arranged on the outside of the upper end of the clamping rod 32. The clamping sleeve 331 is rotatably connected to the clamping rod 32 through a rotating plate 332 fixedly installed at its lower end. A one-way bearing 333 is also installed between the clamping sleeve 331 and the clamping rod 32.

[0044] See Figure 3 and Figure 5 The toggle group 45 includes a mating sleeve 451 movably mounted on the outside of the clamping rod 32, and the clamping rod 32 passes through the mating sleeve 451, and two circumferentially evenly arranged arc-shaped shift blocks 452 are fixedly mounted on the inside of the mating sleeve 451, and the upper side of the arc-shaped shift blocks 452 is provided with an inclined surface; the mating sleeve 451 is connected to the connecting ring 432 through two symmetrically arranged L-shaped connecting rods 453, and the connecting ends of the L-shaped connecting rods 453 and the connecting ring 432 are configured as a telescopic structure; two circumferentially evenly arranged mating columns 321 are fixedly mounted on the outside of the clamping rod 32, and the mating columns 321 and the corresponding arc-shaped shift blocks 452 are configured to be in contact with each other on the inclined surface. When the clamping rod 32 moves downward, the mating columns 321 drive the clamping rod 32 to rotate under the action of the inclined surface of the corresponding arc-shaped shift blocks 452.

[0045] It should be noted that the one-way bearing 333 adopts the existing technology, which can rotate freely in one direction and is locked in the other direction.

[0046] See Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 and Figure 6When the tooth body is in the state of being pressed down, the tooth body 31 is pressed downwards, and the tooth body 31 is in the state of being pressed down. When the tooth body 31 is in the state of being pressed down, the tooth body 31 is in the state of being pressed down. When the tooth body 31 is in the state of being pressed down, the tooth body 31 is in the state of being pressed down. The L-shaped connecting rod 453 is connected to the connecting ring 432, so that the mating sleeve 451 cannot rotate about its central axis. The clamping rod 32 drives the mating column 321 to move downward, and the mating column 321 and the inclined surface of the arc-shaped shift block 452 cooperate to drive the corresponding clamping rod 32 to rotate, but at this time the one-way bearing 333 is in a locked state, so the clamping rod 32 drives the transmission sleeve 312 to rotate together through the one-way bearing 333, and rotates about the central axis of the clamping rod 32. Since the transmission sleeve 312 is provided with multiple and circumferentially uniformly clamped on the outside of the cylindrical part of the tooth body, and the overall mass of the pick is relatively light, the transmission sleeve 312 rotates synchronously, in the same direction, and at the same speed, and then the multiple self-rotating transmission sleeves 312 use friction to make the tooth body rotate relative to the transmission sleeve 312, thereby changing the clamping position of the transmission sleeve 312 on the tooth body.

[0047] When the clamping rod 32 moves upward to the initial position, the matching column 321 does not contact the arc-shaped shift block 452, and the clamping rod 32 rotates to the initial position under the action of the torsion spring at the rotation connection between it and the sliding block 313. During this process, the one-way bearing 333 is in an unlocked state, that is, the clamping rod 32 rotates relative to the clamping sleeve 331, and then when the clamping rod 32 shakes up and down, the clamping sleeve 331 can intermittently rotate in one direction, so that the clamping position of the clamping sleeve 331 on the tooth body changes intermittently, and then the tooth body surface can be evenly heated. When the starting active part 311 drives multiple transmission sleeves 312 to move outward synchronously, the transmission sleeve 312 drives multiple clamping sleeves 331 to loosen the tooth body through the clamping rod 32 and the rotating plate 332.
