Description

Technical Field

[0001] This application relates to the technical field of chain plate processing, and in particular to a processing tool for die-forged chain plates. Background Art

[0002] A die-forged chain plate is a kind of chain plate manufactured by die-forging process, and is usually used in a chain drive system. Die-forging is a metal processing technology, in which the metal is heated to a certain temperature and then pressure is applied in a mold to form the required shape. Die-forged chain plates usually have high strength and wear resistance, and are suitable for heavy-load and high-speed drive systems.

[0003] After partial die-forged chain plates are stamped and formed, they need to be fixed on a tooling for further processing. An automatic clamping tooling for chain plate processing disclosed in the publication number: CN102729071B sleeved the die-forged chain plate on a positioning column to limit the swing of the die-forged chain plate on the workbench during processing. Then, the corner cylinder first drives the pressing plate to rotate above the die-forged chain plate, and the corner cylinder drives the pressing plate to descend, so that the pressing plate presses on the upper surface of the die-forged chain plate to fix the die-forged chain plate and limit the up-and-down shaking of the die-forged chain plate during processing.

[0004] In view of the above related technologies, when processing some die-forged chain plates, it is necessary to mill and polish the inner wall and part of the surface of the chain holes of the die-forged chain plates to make the surface and edges of the die-forged chain plates smoother. However, the tooling disclosed in the above patent and the currently existing tooling cannot be used to clamp die-forged chain plates that need to mill the inner wall and part of the surface of the chain holes. Utility Model Content

[0005] In order to enable the die-forged chain plate after clamping to directly mill the inner wall and part of the surface of the chain holes, this application provides a processing tooling for die-forged chain plates.

[0006] The processing tooling for die-forged chain plates provided by this application adopts the following technical solutions:

[0007] A processing tooling for die-forged chain plates includes a processing base, a first positioning plate, a second positioning plate, a first driving member, a pressing block and an adjusting member;

[0008] The first positioning plate is slidably arranged on the processing base, the second positioning plate is arranged on the processing base, and the first positioning plate and the second positioning plate are arranged opposite to each other;

[0009] The first driving member is arranged on the processing base, the first driving member is connected to the first positioning plate, and the first driving member drives the first positioning plate to approach or move away from the second positioning plate;

[0010] The processing base is provided with a second driving member, the second driving member is connected to the adjusting member, the adjusting member is connected to the pressing block, the adjusting member is used to adjust the position of the pressing block so that the pressing block is aligned with the upper edge of the chain plate, and the second driving member drives the adjusting member and the pressing block to perform lifting movements in turn.

[0011] By adopting the above technical scheme, when clamping the chain plate, the position of the pressure block is adjusted by the adjusting member according to the size of the chain plate, and then one end of the chain plate is contacted with the second positioning plate, and at the same time, the pressure block is aligned with the upper edge of the chain plate, and the other end of the chain plate is facing the first positioning plate, and then the first driving member drives the first positioning plate to move in the direction close to the second positioning plate, so that the first positioning plate and the second positioning plate clamp the chain plate, and limit the chain plate from swinging left and right on the processing base. Finally, the second driving member drives the pressure block to press the upper edge of the chain plate, and limit the chain plate from shaking up and down on the processing base, so that the clamped die-forged chain plate can be directly milled on the inner wall of the chain hole and part of the surface.

[0012] Optionally, the first positioning plate is provided with a first positioning groove, and the second positioning plate is provided with a second positioning groove. When the first positioning plate and the second positioning plate clamp the chain plate, the groove wall of the first positioning groove has at least two line contacts with the circumferential surface of the end of the chain plate, and the groove wall of the second positioning groove has at least two line contacts with the circumferential surface of the end of the chain plate.

[0013] By adopting the above technical solution, when clamping the chain plate, first abut one end of the chain plate against the wall of the second positioning groove, and face the other end of the chain plate toward the first positioning groove. When the first positioning plate approaches the second positioning plate, the wall of the first positioning groove contacts the chain plate and gradually corrects the chain plate, so that the position of the chain plate after each clamping is uniform, automatic calibration is achieved, and processing is convenient. At the same time, the slippage of the chain plate and the circumference of the first positioning plate and the circumference of the second positioning plate during the clamping process is reduced.

[0014] Optionally, a plurality of the first positioning plate, the second positioning plate, the first driving member, the pressing block, the adjusting member and the second driving member are provided.

[0015] By adopting the above technical solution, multiple chain plates can be clamped at the same time, thereby improving processing efficiency.

[0016] Optionally, the number of the first positioning plates is at least twice the number of the second positioning plates, each of the second positioning plates corresponds to at least two of the first positioning plates, each of the second positioning plates has at least two of the second positioning grooves, and the second positioning grooves correspond one-to-one to the first positioning grooves.

[0017] By adopting the above technical solution, when clamping chain plates of different sizes, it is necessary to first adjust the position of the second positioning plate to move the second positioning plate away from or closer to the first positioning plate. One second positioning plate corresponds to multiple first positioning plates. Reducing the number of second positioning plates can reduce the adjustment time of the second positioning plate and further improve the processing efficiency.

[0018] Optionally, a plurality of first adjustment holes are formed in the processing base, and the first adjustment holes are arranged in a plurality of rows and a plurality of columns. The second positioning plate is aligned with the first adjustment holes in the same row, and the second positioning plate is bolted to the processing base through the first adjustment holes.

[0019] By adopting the above technical solution, aligning the second positioning plate with the first adjustment holes in different rows and performing bolt connection can achieve the adjustment of the position of the second positioning plate.

[0020] Optionally, the adjusting member includes a linkage rod. A long slot is formed in the linkage rod, and a fixing hole is formed in the pressing block. The fixing hole communicates with the long slot. The long slot is arranged along the direction close to the die-forged chain plate. The linkage rod and the pressing block are detachably connected through the fixing hole and the long slot.

[0021] By adopting the above technical solution, moving the pressing block along the length direction of the linkage rod, and then through the cooperation of the fixing hole and the long slot, fixing the pressing block on the linkage rod with bolts or plug-in members can achieve the adjustment of the position of the pressing block, so that the pressing block can be aligned with the upper surface edge of chain plates of different sizes.

[0022] Optionally, a first slot is formed in the first positioning plate, and the first slot communicates with the first positioning groove. A second slot is formed in the second positioning plate, and the second slot communicates with the second positioning groove;

[0023] One end of the linkage rod corresponds to the first positioning plate, and the other end corresponds to the second positioning plate. Pressing blocks are detachably connected to both ends of the linkage rod. One pressing block corresponds to the first slot and can extend into the first slot, and the other pressing block corresponds to the second slot and can extend into the second slot.

[0024] By adopting the above technical solution, before fixing the chain plate, adjust the positions of the two pressing blocks so that one pressing block is located in the second slot, and then insert one end of the chain plate into the second positioning groove. At this time, the pressing block located in the second slot is aligned with the upper surface edge of one end of the chain plate;

[0025] Then, the first driving member drives the first positioning plate to move. When the other end of the chain plate is stuck into the first positioning groove, the other pressing block is located in the first slot, and the pressing block located in the first slot is aligned with the upper surface edge of the other end of the chain plate. Then, the second driving member drives the two pressing blocks to press the chain plate simultaneously, completing the fixation of the chain plate. The settings of the first slot and the second slot enable the pressing blocks not to interfere with the first positioning plate and the second positioning plate. The relative movement directions of the two pressing blocks, the first positioning plate, and the second positioning plate are all in the same straight-line direction. Thus, the occupied space of the first positioning plate, the second positioning plate, and the pressing blocks in the same group on the processing base can be reduced, allowing more first positioning plates, second positioning plates, and pressing blocks to be arranged on one processing base to clamp more chain plates simultaneously.

[0026] Optionally, the long slots at the end of the link rod corresponding to the second positioning plate are replaced with a plurality of second adjustment holes, and the arrangement direction of the second adjustment holes is parallel to the arrangement direction of each column of the first adjustment holes.

[0027] By adopting the above technical solution, before adjusting the second positioning plate, adjust the pressing block according to which column of the first adjustment holes the second positioning plate needs to be aligned with, so that the pressing block is connected to the link rod through the corresponding second adjustment hole, thereby quickly completing the position adjustment of the second positioning plate and the pressing block and keeping the relative position of the second positioning plate and the pressing block unchanged all the time.

[0028] Optionally, a clamping groove is formed on the first positioning plate, and the first driving member is connected with a clamping block located in the clamping groove. When the first driving member drives the clamping block to move, the clamping block abuts against the side wall of the clamping groove. When the first positioning plate moves in the vertical direction, the clamping block can be separated from the clamping groove. A supporting block is arranged on the processing base to support the first positioning plate, and a plurality of limiting plates are detachably connected to the processing base, and both sides of the first positioning plate are attached to the limiting plates on the same side.

[0029] By adopting the above technical solution, the first driving member pushes the clamping block to move, and the clamping block always abuts against the side wall of the clamping groove during the movement, thereby realizing the first driving member driving the first positioning plate to move. During the movement of the first positioning plate, the limiting plates are always attached to the side wall of the first positioning plate to guide the first positioning plate, and the supporting block elevates the first positioning plate, with a part of the bottom surface of the first positioning plate in a suspended state. Thus, the friction force received by the first positioning plate during movement is reduced, making the movement of the first positioning plate smoother.

[0030] Optionally, a slag removal hole is formed on the processing base, and the slag removal hole is communicated with the chain holes of the chain plate.

[0031] By adopting the above technical solution, when milling and grinding the chain hole of the chain plate, the waste chips can be discharged from the slag removal hole to the bottom of the processing base, avoiding the accumulation of waste chips between the chain hole and the processing base, causing the waste chips to scratch the chain hole during the grinding process, and at the same time reducing the amount of waste chips remaining on the processing base, affecting the processing of subsequent workpieces.

[0032] In summary, the present application includes at least one of the following beneficial technical effects:

[0033] 1. When clamping the chain plate, according to the size of the chain plate, use the adjusting member to adjust the position of the pressing block, then contact one end of the chain plate with the second positioning plate, align the pressing block with the upper edge of the chain plate, and move the other end of the chain plate toward the first positioning plate, and then the first driving member drives the first positioning plate to move in the direction close to the second positioning plate, so that the first positioning plate and the second positioning plate clamp the chain plate, and limit the chain plate from swinging left and right on the processing base. Finally, the second driving member drives the pressing block to press the upper edge of the chain plate, and limit the chain plate from swinging up and down on the processing base, so that the clamped die-forged chain plate can be directly milled on the inner wall of the chain hole and part of the surface;

[0034] 2. Multiple chain plates can be clamped at the same time to improve processing efficiency;

[0035] 3. The space occupied by the first positioning plate, the second positioning plate and the pressing block of the same group on the processing base can be reduced, so that more first positioning plates, second positioning plates and pressing blocks can be arranged on one processing base to clamp more chain plates at the same time.

[0047] The first positioning plates 2 are placed on two adjacent support blocks 14. The two sides of the first positioning plates 2 are respectively fitted with the side surfaces of the limiting plates 13 on the same side. The first positioning plate 2 has a snap-in groove 21 at one end facing the first driving member 11. The snap-in groove 21 is a convex groove.

[0049] like Figure 2 and Figure 5 Six second driving members 18 are installed in the cavity of the processing base 1. In the embodiment of the present application, the second driving member 18 is a cylinder. In other embodiments, the second driving member 18 can be an electric cylinder, a hydraulic cylinder or a motor with a lead screw; each second driving member 18 corresponds to a first driving member 11 one by one, and the second driving member 18 is arranged between the corresponding two slag removal holes 15, and the piston rod of the second driving member 18 is arranged vertically downward;

[0050] The piston rod of the second driving member 18 is connected with an adjusting member 4. The adjusting member 4 includes a linkage rod 41. Both ends of the linkage rod 41 are located below the slag removal holes 15 on the same side. One end of the linkage rod 41 close to the first positioning plate 2 is provided with a long hole 42. The long hole 42 is an oval hole and is arranged along the length direction of the linkage rod 41. There are two pressing blocks 5 arranged on one side of the linkage rod 41. The pressing blocks 5 are provided with fixing holes 51. The fixing hole 51 of one pressing block 5 communicates with the long hole 42. The pressing block 5 and the linkage rod 41 are fixed by a fixing bolt passing through the long hole 42 and the fixing hole 51 in sequence and using a fixing nut to fix the pressing block 5 and the linkage rod 41. The pressing block 5 extends out from the slag removal holes 15 on the same side and faces the first slot 23. A plurality of second adjusting holes 43 are provided at one end of the linkage rod 41 close to the second positioning plate 3. The second adjusting holes 43 are arranged at equal intervals along the length direction of the linkage rod 41. The fixing hole 51 of the other pressing block 5 corresponds to one of the second adjusting holes 43. The pressing block 5 and the linkage rod 41 are fixed by a fixing bolt passing through the second adjusting hole 43 and the fixing hole 51 in sequence and using a fixing nut to fix the pressing block 5 and the linkage rod 41. The pressing block 5 extends out from the slag removal holes 15 on the same side and extends into the second slot 32.

[0051] The pressing block 5 is an L-shaped block. One end of the pressing block 5 close to the linkage rod 41 is provided with a stepped groove 52. The pressing block 5 is supported on the linkage rod 41 through the stepped groove 52.

[0052] As Figure 1 , there are two main air supply valves 6 arranged on one side of the processing base 1. One main air supply valve 6 supplies air to all the first driving members 11, and the other main air supply valve 6 supplies air to all the second driving members 18. The main air supply valve 6 is provided with an operating handle 61 for controlling opening and closing.

[0053] Before fixing the chain plate, according to the size of the chain plate, it is necessary to first adjust the positions of the two pressing blocks 5 and the position of the second positioning plate 3: Move one pressing block 5 along the length direction of the linkage rod 41, and then through the cooperation of the fixing hole 51 and the long hole 42, fix the pressing block 5 on the linkage rod 41 with bolts. Then, according to which column of the first adjusting holes 16 the second positioning plate 3 needs to be aligned with, adjust the other pressing block 5 so that the other pressing block 5 is connected to the linkage rod 41 through the corresponding second adjusting hole 43. Then, adjust the second positioning plate 3 to align with one column of the first adjusting holes 16 and fix it with bolts, so that the position adjustment of the second positioning plate 3 and the pressing block 5 can be quickly completed, and the relative positions of the second positioning plate 3 and the pressing block 5 can always be kept unchanged.

[0054] When fixing the chain plate, first place the chain plate on the spacer block 17, then abut one end of the chain plate against the wall of the second positioning groove 31, and orient the other end of the chain plate towards the first positioning groove 22. Start the first driving member 11, and the first driving member 11 pushes the clamping block 12 to move. The clamping block 12 always abuts against the side wall of the clamping groove 21 during the movement, so as to realize the first driving member 11 driving the first positioning plate 2 to move. During the process of the first positioning plate 2 approaching the second positioning plate 3, the wall of the first positioning groove 22 contacts the chain plate and gradually corrects the chain plate, realizing the clamping of the chain plate by the first positioning plate 2 and the second positioning plate 3, restricting the left and right swing of the chain plate on the processing base 1. At this time, the pressing block 5 is aligned with the edge of the upper surface of the chain plate. Start the second driving member 18, and the second driving member 18 drives the pressing block 5 to press the edge of the upper surface of the chain plate, restricting the up and down shaking of the chain plate on the processing base 1, so that the die-forged chain plate after clamping can directly perform milling on the inner wall and part of the surface of the chain hole.

[0055] When milling and grinding the chain holes of the chain plate, the waste chips can be discharged from the slag removal hole 15 to the bottom of the processing base 1, avoiding the accumulation of waste chips between the chain holes and the processing base 1, which may cause the waste chips to scratch the chain holes during the grinding process, and at the same time reducing the amount of waste chips remaining on the processing base 1, which may affect the processing of subsequent workpieces.

[0056] Moreover, multiple chain plates can be placed on the processing base 1 at the same time. Just sequentially open the two main valves controlling the first driving member 11 and the second driving member 18, and the clamping of multiple chain plates can be carried out simultaneously, improving the processing efficiency.

[0057] The implementation principle of the embodiment of the present application is: when clamping the chain plate, according to the size of the chain plate, use the adjusting member 4 to adjust the position of the pressing block 5, then make one end of the chain plate contact the second positioning plate 3, and at the same time align the pressing block 5 with the edge of the upper surface of the chain plate, and orient the other end of the chain plate towards the first positioning plate 2. Then the first driving member 11 drives the first positioning plate 2 to move towards the second positioning plate 3, realizing the clamping of the chain plate by the first positioning plate 2 and the second positioning plate 3, restricting the left and right swing of the chain plate on the processing base 1. Finally, the second driving member 18 drives the pressing block 5 to press the edge of the upper surface of the chain plate, restricting the up and down shaking of the chain plate on the processing base 1, so that the die-forged chain plate after clamping can directly perform milling on the inner wall and part of the surface of the chain hole.

[0058] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
