Description

Technical Field

[0001] The invention relates to the technical field of stamping machinery, and in particular to a stamping machinery for batch processing of electric machinery parts. Background Art

[0002] When producing and processing plate-shaped electric machinery parts, since the plate-shaped electric machinery parts are thin and prone to deformation, it is usually necessary to stamp and shape the electric machinery parts to remove local deformation so that they can be in a flat state. At this time, stamping machinery is needed.

[0003] However, with regard to the currently available stamping machinery, when stamping a batch of plate-shaped electric machinery parts, the loading, processing and unloading of the plate-shaped electric machinery parts are all carried out separately, which not only makes the overall equipment bulky and space-consuming, but also requires staff to monitor between each step to ensure the continuity of the equipment. The separate execution of multiple steps not only makes the stamping process time-consuming and labor-intensive, but also easily causes wear to the parts when changing workstations. Therefore, the present invention solves the shortcomings of the above-mentioned technical problems. Summary of the invention

[0004] Based on the above existing technical problems, the present invention proposes a stamping machine for batch processing of electric machinery parts.

[0005] The present invention proposes a stamping machine for batch processing of electric machinery parts, comprising a feed conveyor belt and a feed conveyor belt, a support frame is arranged above the conveying end of the feed conveyor belt, the inner surface of the support frame is rotatably connected with a regular hexagonal workstation roller through a bearing, the outer surface of the workstation roller is provided with a plurality of positioning mechanisms distributed in a ring array, a stamping mechanism is arranged above the workstation roller, a material picking mechanism is arranged in front of the workstation roller, and a linkage mechanism is arranged between the stamping mechanism and the material picking mechanism.

[0006] Wherein, the positioning mechanism adsorbs the plate-shaped power accessories on the feed conveyor belt to the surface of the station roller and clamps and fixes them.

[0007] The punching mechanism reciprocates up and down to press and punch holes in the multiple plate-shaped power accessories clamped and fixed on the surface of the station roller one by one.

[0008] The material taking mechanism absorbs the stamped plate-shaped power accessories, so that they are separated from the station rollers and placed on the surface of the feeding conveyor belt for transmission.

[0009] Wherein, the linkage mechanism drives the stamping mechanism and the material taking mechanism synchronously.

[0010] Preferably, the positioning mechanism includes positioning grooves synchronously opened on multiple surfaces of the work station roller, a vacuum adsorption plate is slidably and retractably provided in the positioning groove, a punching groove is penetrated through the upper surface of the vacuum adsorption plate, and multiple telescopic hydraulic rods are installed inside the work station roller, and the upper surface of the telescopic end of the telescopic hydraulic rod is fixedly connected to the lower surface of the corresponding vacuum adsorption plate.

[0011] Through the above technical scheme, in order to pick up the plate-like power accessories transported in batches on the feed conveyor and facilitate the stamping and punching of their surfaces, after the plate-like power accessories are transported to the front end of the feed conveyor, the workstation roller rotates intermittently, so that multiple positioning grooves are aligned with the plate-like power accessories on the feed conveyor in turn, and then the vacuum adsorption plate is pushed to the upper surface of the plate-like power accessories through the telescopic hydraulic rod, so that the vacuum adsorption plate adsorbs it and then resets it, so that the plate-like power accessories are brought into the positioning groove, so that the reciprocating stamping mechanism stamps the batch of plate-like power accessories in turn, and the setting of the punching groove can facilitate the punching treatment of the surface of the plate-like power accessories.

[0012] Preferably, the positioning mechanism also includes a clamping positioning plate that is symmetrically distributed and slidingly attached to the inner wall of the positioning groove, the lower surface of the clamping positioning plate is slidably connected to the upper surface of the vacuum adsorption plate, the interior of the work station roller is respectively provided with an L-shaped telescopic groove and a plurality of telescopic holes, the inner wall of the telescopic groove is slidably connected with a telescopic rod, and one side surface of the telescopic rod is fixedly connected to one side surface of the clamping positioning plate.

[0013] Through the above technical scheme, in order to control the plate-shaped power accessory to be centrally set in the positioning groove to achieve the purpose of positioning it, after the vacuum adsorption plate drives the plate-shaped power accessory to reset, the four clamping positioning plates move forward synchronously, so that the four sides of the plate-shaped power accessory can be clamped at the same time, which not only realizes its clamping and fixing, but also realizes its positioning and adjustment through the extrusion of the clamping force, thereby achieving precise stamping and punching. In order to realize the extension and retraction of the clamping positioning plate, after the stamping mechanism is inserted from the top of the telescopic groove, the telescopic rod extends horizontally from the telescopic groove, thereby pushing the clamping positioning plate.

[0014] Preferably, the positioning mechanism also includes an oblique groove extending through the upper surface of the telescopic rod, a reset rod is fixedly connected to one side surface of the telescopic rod, the outer surface of the reset rod slides and telescopes with the inner wall of the telescopic hole, a reset spring is fixedly sleeved on the outer surface of the rear end of the reset rod, and the free end of the reset spring is fixedly connected to the inner wall of the telescopic hole.

[0015] Through the above technical scheme, in order to push the telescopic rod when the stamping mechanism descends, the special opening of the oblique square groove can enable the stamping mechanism to push the telescopic rod along the inclined path of the oblique square groove when it descends, and lose the squeezing of the telescopic rod when the stamping mechanism is reset. When the reset spring is reset, the reset rod drives the telescopic rod to reset, and after one stamping is completed, the positioning clamping plate loses its clamping of the stamped plate-shaped power accessory, so that the material picking mechanism can pick it up.

[0016] Preferably, the stamping mechanism includes a stamping plate arranged above the work station roller, the lower surface of the stamping plate is symmetrically distributed and fixedly connected with stamping blocks, the outer surface of the stamping block is slidably connected to the inner wall of the punching groove, the upper surface of the stamping plate is fixedly connected with a rectangular frame, the lower surface of the rectangular frame is symmetrically distributed and fixedly connected with extrusion blocks, and the outer surface of the extrusion block is slidably connected to the inner wall of the oblique square groove.

[0017] Through the above technical scheme, in order to stamp and flatten the upper surface of the plate-shaped power accessories and punch holes at the same time, the rectangular frame moves downward a specific distance, which can drive the stamping plate to press against the clamped surface of the plate-shaped power accessories to complete the flattening process. At the same time, the punching block presses against the punching slot to realize the punching process. The rectangular frame is reset after it descends. At this time, the work station roller also rotates intermittently once, so that another accessory to be stamped is flipped to the upper surface, and then the rectangular frame is repeatedly descended for stamping, and the accessories that have been stamped are taken out when they are flipped to one side.

[0018] Preferably, the stamping mechanism also includes guide blocks symmetrically distributed and fixedly connected to the outer surface of the rectangular frame, the inner surface of the support frame is fixedly connected to the guide rail via a connecting block, the inner surface of the guide block is slidably engaged with the outer surface of the guide rail, and the upper surface of the rectangular frame and the inner surface of the support frame are fixedly connected with a buffer telescopic rod with a buffer spring.

[0019] Through the above technical solution, in order to achieve precise stamping, the reciprocating rectangular frame is guided and limited, and the moving path of the rectangular frame is controlled by the cooperation of the guide block and the guide slide rail. In order to buffer the reciprocating rectangular frame, the buffer telescopic rod pulls the upper surface of the rectangular frame.

[0020] Preferably, the stamping mechanism also includes a stamping shaft that passes through the rectangular frame and is rotatably connected to the surface of the support frame through a bearing, both ends of the stamping shaft are rotatably sleeved with limit blocks, movable holes are opened through the two side surfaces of the rectangular frame, the stamping shaft passes through the movable holes, the outer surface of the limit block is slidably engaged with the outer surface of the rectangular frame, a cam block is fixedly sleeved on the middle outer surface of the stamping shaft, and an arc-shaped boss is fixedly connected to the inner bottom surface of the rectangular frame, and the surface of the cam block is in sliding contact with the surface of the arc-shaped boss.

[0021] Through the above technical solution, in order to drive the rectangular frame to move up and down reciprocatingly, the cam block is driven to rotate when the punching shaft rotates, so that when the convex surface of the cam block is squeezed with the arc-shaped boss, the rectangular frame can be squeezed to move downward, and when the convex surface of the cam block rotates to the inner top surface of the rectangular frame, the rectangular frame is reset, and when the rectangular frame moves back and forth, the movable hole of the rectangular frame slides on the outer surface of the punching shaft through the clamping of the limit block.

[0022] Preferably, the material picking mechanism includes a suction cup clamp arranged on the front side of the work station roller, the upper surface of the suction cup clamp is fixedly connected to a U-shaped movable frame, the inner surface of the support frame is rotatably connected to a support shaft, the outer surface of the support shaft is fixedly connected to a reset telescopic shaft, and the telescopic end of the reset telescopic shaft is fixedly connected to the upper surface of the movable frame.

[0023] Through the above technical solution, when the stamped plate-shaped power accessories are rotated to one side of the suction cup clamp, the support shaft rotates and deflects, so that the suction cup of the vertical suction cup clamp faces the surface of the work station roller. The suction cup clamp can be pushed to the surface of the accessory for adsorption by resetting the telescopic shaft. After the suction cup clamp is reset, the adsorbed plate-shaped power accessories can be placed on the feed conveyor belt for transportation.

[0024] Preferably, the material picking mechanism also includes a driving shaft rotatably connected to the inner surface of the support frame, a driving rod is fixedly sleeved on the middle outer surface of the driving shaft, the free end of the driving rod is hinged to the outer surface of the movable frame, the outer surfaces of both ends of the driving shaft are fixedly connected to eccentric rods, the outer surfaces of both ends of the stamping shaft are fixedly connected to power rods, and the surfaces of the power rod and the surfaces of the eccentric rod are hinged with a linkage shaft.

[0025] Through the above technical scheme, in order to drive the suction cup clamp to deflect and pick up materials, the punching shaft drives the power rod to rotate in a uniform circumferential direction when rotating, and the eccentric rod can be pulled by the linkage shaft to rotate in a fan shape. When the eccentric rod rotates in a fan shape, it can drive the driving shaft to rotate forward and reverse, thereby making the driving rod deflect forward and reverse. When it deflects counterclockwise when viewed from the side, it can drive the movable frame to deflect counterclockwise, so that the suction cup clamp is close to the work station roller for adsorption, and resets clockwise after picking up the material, so that the accessories can be released.

[0026] Preferably, the linkage mechanism includes a groove wheel fixedly sleeved on the outer surface of one end of the roller shaft of the work station roller, one side surface of the support frame is fixedly connected to a mounting frame, the outer surface of one end of the stamping shaft and the outer surface of the roller shaft of the work station roller are rotatably connected to the inner surface of the mounting frame through a bearing, the outer surface of the stamping shaft is fixedly sleeved with a transmission gear, one side surface of the support frame is rotatably connected with a linkage gear through a connecting shaft, the transmission gear is meshed with the linkage gear, the outer surface of the connecting shaft of the linkage gear is fixedly sleeved with a paddle wheel, the surface of the paddle wheel is fixedly connected with a protruding paddle roller, the outer surface of the paddle wheel is slidably connected to the concave surface of the groove wheel, the outer surface of the paddle roller is slidably engaged with the groove surface of the groove wheel, the outer surface of the mounting frame is fixedly connected with a reduction motor, and the outer surface of the output shaft of the reduction motor drives the stamping shaft to rotate through a bevel gear set.

[0027] Through the above technical scheme, in order to drive the punching shaft to rotate to realize the rotation of the cam block and drive the rectangular frame to move up and down reciprocatingly, the reduction motor realizes the uniform circumferential rotation of the punching shaft through the bevel gear group, and the uniform circumferential rotation of the punching shaft can drive the linkage shaft to pull the driving shaft of the material-taking mechanism to rotate forward and reversely. In order to drive the workstation roller to rotate intermittently and facilitate the material loading and taking operations on its surface, the punching shaft rotates, causing the transmission gear to rotate, which can drive the linkage gear to rotate. When the pulley on one side of the linkage gear contacts the concave surface of the groove wheel, the workstation roller does not rotate. When the pulley rotates into the slot of the groove wheel, the workstation roller can be pulled to rotate once, and the upper surface of the workstation roller is stamped, the lower surface is loaded, and one side of the material is taken during the intermittent time of the groove wheel. Therefore, through the linkage between the stamping mechanism and the material-taking mechanism, the stamping equipment has continuity and simple operation, which can improve the efficiency of batch processing and stamping of electric machinery parts.

[0028] The beneficial effects of the present invention are: 1. By setting up a positioning mechanism, the accessories on the feed conveyor belt can be picked up, and the surrounding side surfaces can be clamped and fixed. During the adjustment process, the vacuum adsorption plate is pushed to the upper surface of the plate-shaped power accessories through the telescopic hydraulic rod in the positioning groove, so that the vacuum adsorption plate adsorbs it, and the extrusion block is inserted into the oblique square groove of the telescopic rod, and continues to move downward along the inclined path of the oblique square groove, so that the telescopic rod can be squeezed to extend out of the telescopic groove, thereby pushing the clamping positioning plate, and the four clamping positioning plates move forward synchronously, so that the four sides of the plate-shaped power accessories can be clamped at the same time, which not only realizes its clamping and fixing, but also realizes its positioning adjustment through the extrusion of the clamping force, and can also place the warped edges of the accessories.

[0029] 2. By setting up a stamping mechanism, multiple plate-shaped power accessories clamped and fixed on the surface of the workstation roller can be pressed one by one and punched to open holes. During the adjustment process, the rotating stamping shaft just drives the convex surface of the cam block to squeeze the arc-shaped boss. At this time, the extrusion rectangular frame moves downward, driving the stamping plate to press against the plate-shaped power accessories in the positioning groove. When the stamping plate moves downward with the rectangular frame, the surface of the plate-shaped power accessories can be stamped flat, and the stamping block presses against the punching groove to realize punching processing. Through mechanical stamping, a large number of accessories can be produced in a very short time, which is suitable for mass production.

[0030] 3. By setting up a material-picking mechanism, the stamped plate-shaped power accessories can be adsorbed, so that they can be separated from the position roller and placed on the surface of the feed conveyor belt for transmission. During the adjustment process, the rotation of the stamping shaft drives the power rod to rotate circumferentially at a uniform speed, and the eccentric rod can be pulled by the linkage shaft to rotate in a fan shape. When the eccentric rod rotates in a fan shape, it can drive the drive shaft to rotate forward and reverse, thereby causing the drive rod to deflect forward and reverse, so that the suction cup of the vertical suction cup clamp faces the surface of the station roller. The suction cup clamp can be pushed to the surface of the accessory for adsorption by resetting the telescopic shaft. When the suction cup clamp is reset, the adsorbed plate-shaped power accessories can be placed on the feed conveyor belt for transportation, thereby improving the continuity of the overall equipment.

[0031] 4. By setting up a linkage mechanism, the stamping mechanism and the material-retrieving mechanism can be driven synchronously. During the adjustment process, the uniform circumferential rotation of the stamping shaft can drive the linkage shaft to pull the driving shaft of the material-retrieving mechanism in forward and reverse rotation, so that it can complete the action of retrieving and releasing materials. At the same time, when the stamping shaft rotates at a uniform speed, the transmission gear rotates, which can drive the linkage gear to rotate. When the pulley on one side of the linkage gear contacts the concave surface of the groove wheel, the station roller does not rotate. When the pulley rotates into the groove of the groove wheel, it can drive the station roller to rotate once, and complete the stamping of the upper surface of the station roller, the loading of the lower surface and the retrieving of one side during the intermittent time of the groove wheel. Therefore, the groove wheel of this set of equipment moves intermittently, and the stamping is linked with the picking and placing, so that the processing of accessories is continuous, thereby improving its processing efficiency.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Reference Figure 1-Figure 13 A stamping machine for batch processing of electric machinery parts includes a feed conveyor belt 1 and a feed conveyor belt 2. A support frame 3 is arranged above the conveying end of the feed conveyor belt 1. The inner surface of the support frame 3 is rotatably connected to a regular hexagonal station roller 4 through a bearing. The outer surface of the station roller 4 is provided with a plurality of positioning mechanisms 5 distributed in a ring array. A stamping mechanism 7 is arranged above the station roller 4, a material picking mechanism 8 is arranged in front of the station roller 4, and a linkage mechanism 9 is arranged between the stamping mechanism 7 and the material picking mechanism 8.

[0036] The positioning mechanism 5 absorbs the plate-shaped power accessories on the feed conveyor belt 1 to the surface of the station roller 4 and clamps and fixes them.

[0037] In order to facilitate the stamping and punching of the surface of the plate-shaped power accessories transported in batches on the feed conveyor belt 1, the positioning mechanism 5 includes positioning grooves 51 synchronously opened on multiple surfaces of the station roller 4, and a vacuum adsorption plate 52 is slidably and retractably arranged in the positioning groove 51. The upper surface of the vacuum adsorption plate 52 is penetrated by a punching groove 53, and a plurality of telescopic hydraulic rods 54 are installed inside the station roller 4. The upper surface of the telescopic end of the telescopic hydraulic rod 54 is fixedly connected to the lower surface of the corresponding vacuum adsorption plate 52, and the plate-shaped power accessories are transported to the feed conveyor belt 1. Behind the front end of the conveyor belt 1, the work station roller 4 rotates intermittently, so that the multiple positioning grooves 51 are aligned with the plate-like power accessories on the feed conveyor belt 1 in turn, and then the vacuum adsorption plate 52 is pushed to the upper surface of the plate-like power accessories through the telescopic hydraulic rod 54, so that the vacuum adsorption plate 52 adsorbs it and then resets it, so that the plate-like power accessories are brought into the positioning groove 51, so that the reciprocating stamping mechanism 7 punches the batch of plate-like power accessories in turn, and the setting of the punching groove 53 can facilitate the punching treatment of the surface of the plate-like power accessories.

[0038] In order to control the plate-like power accessories to be centrally set in the positioning groove 51 to achieve the purpose of positioning, the positioning mechanism 5 also includes a clamping positioning plate 55 that is symmetrically distributed and slides on the inner wall of the positioning groove 51. The lower surface of the clamping positioning plate 55 is slidably connected to the upper surface of the vacuum adsorption plate 52. After the vacuum adsorption plate 52 drives the plate-like power accessories to reset, the four clamping positioning plates 55 move forward synchronously, so that the four sides of the plate-like power accessories can be clamped at the same time, which not only achieves its clamping and fixing, but also can achieve its positioning and adjustment through the extrusion of the clamping force, so as to achieve precise stamping and punching. In order to achieve the extension and retraction of the clamping positioning plate 55, the interior of the station roller 4 is respectively provided with an L-shaped telescopic groove 56 and a plurality of telescopic holes 57. The inner wall of the telescopic groove 56 is slidably connected with a telescopic rod 58, and one side surface of the telescopic rod 58 is fixedly connected to one side surface of the clamping positioning plate 55. After the stamping mechanism 7 is inserted from the top of the telescopic groove 56, the telescopic rod 58 extends horizontally from the telescopic groove 56, so that the clamping positioning plate 55 can be pushed.

[0039] In order to push the telescopic rod 58 when the stamping mechanism 7 descends, the positioning mechanism 5 also includes an oblique groove 59 that penetrates and is opened on the upper surface of the telescopic rod 58. A reset rod 60 is fixedly connected to the surface of one side of the telescopic rod 58. The outer surface of the reset rod 60 slides and retracts with the inner wall of the telescopic hole 57. A reset spring 61 is fixedly sleeved on the outer surface of the rear end of the reset rod 60. The free end of the reset spring 61 is fixedly connected to the inner wall of the telescopic hole 57. The special opening of the oblique groove 59 can enable the stamping mechanism 7 to push the telescopic rod 58 along the inclined path of the oblique groove 59 when descending, and lose the squeezing of the telescopic rod 58 when the stamping mechanism 7 is reset. When the reset spring 61 is reset, the reset rod 60 drives the telescopic rod 58 to reset, that is, after one stamping is completed, the positioning clamping plate loses its clamping of the stamped plate-shaped power accessories, so that the material taking mechanism 8 can take the materials from it.

[0040] By setting up the positioning mechanism 5, the accessories on the feed conveyor belt 1 can be picked up, and the peripheral surface thereof can be clamped and fixed. During the adjustment process, the vacuum adsorption plate 52 is pushed to the upper surface of the plate-shaped power accessory by the telescopic hydraulic rod 54 in the positioning groove 51, so that the vacuum adsorption plate 52 adsorbs it, and is inserted into the oblique groove 59 of the telescopic rod 58 through the extrusion block 74, and continues to move downward along the inclined path of the oblique groove 59, so that the telescopic rod 58 can be squeezed to extend out of the telescopic groove 56, so that the clamping positioning plate 55 can be pushed, and the four clamping positioning plates 55 move forward synchronously, so that the four sides of the plate-shaped power accessory can be clamped at the same time, which not only realizes its clamping and fixing, but also realizes its positioning and adjustment through the extrusion of the clamping force, and can also place the warped edges of the accessories on all sides.

[0041] The punching mechanism 7 reciprocates up and down to press and punch holes in the multiple plate-shaped power accessories clamped and fixed on the surface of the station roller 4 one by one.

[0042] In order to punch and level the upper surface of the plate-shaped power accessories and punch holes at the same time, the punching mechanism 7 includes a punching plate 71 arranged above the station roller 4, and the lower surface of the punching plate 71 is symmetrically distributed and fixedly connected with a punching block 72, and the outer surface of the punching block 72 is slidably connected to the inner wall of the punching groove 53. The upper surface of the punching plate 71 is fixedly connected with a rectangular frame 73, and the lower surface of the rectangular frame 73 is symmetrically distributed and fixedly connected with an extrusion block 74, and the outer surface of the extrusion block 74 is slidably connected to the inner wall of the oblique square groove 59. After the rectangular frame 73 moves downward for a specific distance, it can drive the punching plate 71 to press against the surface of the clamped plate-shaped power accessories to complete the leveling process, and at the same time, the punching block 72 presses against the punching groove 53 to realize the punching process. The rectangular frame 73 is reset after it descends, and at this time the station roller 4 also rotates intermittently once, so that another accessory to be punched is turned over to the upper surface, and then the rectangular frame 73 is repeatedly descended for punching, and the accessory that has been completed by stamping is taken out when it is turned to one side.

[0043] In order to ensure precise stamping, the reciprocating rectangular frame 73 is guided and limited. The stamping mechanism 7 also includes guide blocks 75 symmetrically distributed and fixedly connected to the outer surface of the rectangular frame 73. The inner surface of the support frame 3 is fixedly connected to a guide rail 76 through a connecting block. The inner surface of the guide block 75 is slidably engaged with the outer surface of the guide rail 76. The moving path of the rectangular frame 73 is controlled by the cooperation of the guide block 75 and the guide rail 76. In order to buffer the reciprocating rectangular frame 73, the upper surface of the rectangular frame 73 is fixedly connected to the inner surface of the support frame 3 with a buffer telescopic rod 77 with a buffer spring. The buffer telescopic rod 77 pulls the upper surface of the rectangular frame 73.

[0044] In order to drive the rectangular frame 73 to reciprocate up and down, the stamping mechanism 7 also includes a stamping shaft 78 that penetrates the rectangular frame 73 and is rotatably connected to the surface of the support frame 3 through a bearing. Both ends of the stamping shaft 78 are rotatably sleeved with limit blocks 781. The two side surfaces of the rectangular frame 73 are penetrated with movable holes 731. The stamping shaft 78 penetrates the movable holes 731. The outer surface of the limit block 781 is slidably engaged with the outer surface of the rectangular frame 73. The middle outer surface of the stamping shaft 78 is fixedly sleeved with a cam block 79. The inner bottom surface of the rectangular frame 73 is fixed. An arc-shaped boss 732 is connected, and the surface of the cam block 79 is in sliding contact with the surface of the arc-shaped boss 732. When the punch shaft 78 rotates, the cam block 79 is driven to rotate. Therefore, when the convex surface of the cam block 79 is squeezed with the arc-shaped boss 732, the rectangular frame 73 can be squeezed to move downward, and when the convex surface of the cam block 79 rotates to the inner top surface of the rectangular frame 73, the rectangular frame 73 is reset. When the rectangular frame 73 moves back and forth, the movable hole 731 of the rectangular frame 73 slides on the outer surface of the punch shaft 78 through the clamping of the limit block 781.

[0045] By setting up the stamping mechanism 7, multiple plate-like power accessories clamped and fixed on the surface of the work station roller 4 can be pressed one by one and punched to open holes. During the adjustment process, the rotating stamping shaft 78 just drives the convex surface of the cam block 79 to squeeze the arc-shaped boss 732. At this time, the extrusion rectangular frame 73 moves downward, driving the stamping plate 71 to press against the plate-like power accessories in the positioning groove 51. When the stamping plate 71 moves downward with the rectangular frame 73, the surface of the plate-like power accessories can be stamped and flattened, and the stamping block 72 presses against the punching groove 53 to realize the punching process. Through mechanical stamping, a large number of accessories can be produced in a very short time, which is suitable for mass production.

[0046] The material taking mechanism 8 absorbs the stamped plate-shaped power accessories, so that they are separated from the station rollers 4 and placed on the surface of the feeding conveyor belt 2 for transmission.

[0047] The material picking mechanism 8 includes a suction cup clamp 81 arranged on the front side of the work station roller 4, and the upper surface of the suction cup clamp 81 is fixedly connected with a U-shaped movable frame 82, the inner surface of the support frame 3 is rotatably connected with a support shaft 83, and the outer surface of the support shaft 83 is fixedly connected with a reset telescopic shaft 84, and the telescopic end of the reset telescopic shaft 84 is fixedly connected to the upper surface of the movable frame 82. When the stamped plate-shaped power accessories are rotated to one side of the suction cup clamp 81, the support shaft 83 rotates and deflects, so that the suction cup of the vertical suction cup clamp 81 faces the surface of the work station roller 4, and the suction cup clamp 81 can be pushed to the surface of the accessory for adsorption by the telescopic resetting shaft 84. After the suction cup clamp 81 is reset, the adsorbed plate-shaped power accessories can be placed on the feed conveyor 2 for transportation.

[0048] In order to drive the suction cup clamp 81 to deflect and pick up materials, the picking mechanism 8 also includes a driving shaft 85 rotatably connected to the inner surface of the support frame 3, a driving rod 86 is fixedly sleeved on the middle outer surface of the driving shaft 85, and the free end of the driving rod 86 is hinged to the outer surface of the movable frame 82, and the outer surfaces of both ends of the driving shaft 85 are fixedly connected to eccentric rods 87, and the outer surfaces of both ends of the stamping shaft 78 are fixedly connected to power rods 88, and the surface of the power rod 88 is hinged to the surface of the eccentric rod 87. When the linkage shaft 89 and the punch shaft 78 rotate, they drive the power rod 88 to rotate in a uniform circumferential direction, that is, the linkage shaft 89 pulls the eccentric rod 87 to rotate in a fan shape. When the eccentric rod 87 rotates in a fan shape, it can drive the drive shaft 85 to rotate forward and reverse, thereby causing the drive rod 86 to deflect forward and reverse. When it deflects counterclockwise when viewed from the side, it can drive the movable frame 82 to deflect counterclockwise, so that the suction cup clamp 81 is close to the work station roller 4 for adsorption, and resets clockwise after taking the material, so that the accessories can be discharged.

[0049] By setting up the material picking mechanism 8, the stamped plate-shaped power accessories can be adsorbed, so that they can be placed on the surface of the feed conveyor belt 2 for transmission after being separated from the working roller. During the adjustment process, the power rod 88 is driven to rotate in a uniform circumferential direction by the rotation of the stamping shaft 78, and the eccentric rod 87 can be pulled by the linkage shaft 89 to rotate in a fan shape. When the eccentric rod 87 rotates in a fan shape, the driving shaft 85 can be driven to rotate forward and reverse, thereby causing the driving rod 86 to deflect forward and reverse, so that the suction cup of the vertical suction cup clamp 81 faces the surface of the working roller 4, and the suction cup clamp 81 can be pushed to the surface of the accessory for adsorption by resetting the telescopic shaft 84. When the suction cup clamp 81 is reset, the adsorbed plate-shaped power accessories can be placed on the feed conveyor belt 2 for transportation, thereby improving the continuity of the overall equipment.

[0050] The linkage mechanism 9 drives the punching mechanism 7 and the material taking mechanism 8 synchronously.

[0051] In order to drive the punching shaft 78 to rotate and realize the rotation of the cam block 79 to drive the rectangular frame 73 to move up and down reciprocatingly, and at the same time to drive the station roller 4 to present intermittent rotation to facilitate the feeding and taking operations on its surface, the linkage mechanism 9 includes a groove wheel 91 fixedly sleeved on the outer surface of one end of the roller shaft of the station roller 4, and a mounting frame is fixedly connected to the surface of one side of the support frame 3. The outer surface of one end of the punching shaft 78 and the outer surface of the roller shaft of the station roller 4 are both rotatably connected to the inner surface of the mounting frame through a bearing. The outer surface of the punching shaft 78 is fixedly sleeved with a transmission gear 92, and the surface of one side of the support frame 3 is rotatably connected with a linkage gear 93 through a connecting shaft. The transmission gear 92 meshes with the linkage gear 93, and the outer surface of the connecting shaft of the linkage gear 93 is fixedly sleeved with a dial wheel 94, and the surface of the dial wheel 94 is fixedly connected with a protruding dial roller 95, and the outer surface of the dial wheel 94 is slidably connected to the concave surface of the groove wheel 91, and the outer surface of the dial roller 95 is slidably engaged with the groove surface of the groove wheel 91. A reduction motor 96 is fixedly connected to the outer surface of the mounting frame. The outer surface of the output shaft of the reduction motor 96 drives the stamping shaft 78 to rotate through a bevel gear set. The reduction motor realizes the uniform circumferential rotation of the stamping shaft 78 through the bevel gear set, and the uniform circumferential rotation of the stamping shaft 78 can drive the linkage shaft 89 to pull the driving shaft 85 of the material-retrieving mechanism 8 to rotate forward and reverse. At the same time, when the stamping shaft 78 rotates, the transmission gear 92 rotates, which can drive the linkage gear 93 to rotate. When the dial wheel 94 on one side of the linkage gear 93 contacts the concave surface of the groove wheel 91, the station roller 4 does not rotate. When the dial roller 95 rotates into the slot of the groove wheel 91, it can drive the station roller 4 to rotate once, and during the interval of the groove wheel 91, the station roller 4 is stamped on the upper surface, material is fed on the lower surface, and one side of the material is taken. Therefore, through the linkage between the stamping mechanism 7 and the material-retrieving mechanism 8, the stamping equipment has continuity and simple operation, which can improve the efficiency of batch processing and stamping of electric machinery parts.

[0052] By setting the linkage mechanism 9, the punching mechanism 7 and the material picking mechanism 8 can be driven synchronously. During the adjustment process, the uniform circumferential rotation of the punching shaft 78 can drive the linkage shaft 89 to pull the driving shaft 85 of the material picking mechanism 8 in forward and reverse rotation, so that it can complete the material picking and discharging action. At the same time, when the punching shaft 78 rotates at a uniform speed, the transmission gear 92 rotates, which can drive the linkage gear 93 to rotate. When the dial wheel 94 on one side of the linkage gear 93 contacts the concave surface of the groove wheel 91, the station roller 4 does not rotate. When the dial roller 95 rotates into the slot of the groove wheel 91, it can drive the station roller 4 to rotate once, and during the intermittent time of the groove wheel 91, the station roller 4 is stamped on the upper surface, loaded on the lower surface and picked up on one side. Therefore, the groove wheel 91 of this set of equipment moves intermittently, and the stamping is linked with picking and placing, so that the processing of accessories is continuous, thereby improving its processing efficiency.

[0053] Working principle: In a specific embodiment of the present invention, the plate-shaped power accessories are transported on the feed conveyor belt 1. After being transported to the front end of the feed conveyor belt 1, the telescopic hydraulic rod 54 in the positioning groove 51 on the lower surface of the station roller 4 pushes the vacuum adsorption plate 52 to the upper surface of the plate-shaped power accessories, so that the vacuum adsorption plate 52 adsorbs it and resets it, so that the plate-shaped power accessories are brought into the positioning groove 51; When the plate-shaped power fitting in the positioning groove 51 rotates to the top with the station roller 4, the rotating stamping shaft 78 just drives the convex surface of the cam block 79 to squeeze the arc-shaped boss 732. At this time, the extrusion rectangular frame 73 moves downward. During its downward movement, the guide block 75 slides on the outer surface of the guide slide rail 76, and then drives the stamping plate 71 to press against the plate-shaped power fitting in the positioning groove 51. At this time, the extrusion block 74 is inserted into the oblique groove 59 of the telescopic rod 58 and moves along the inclined path of the oblique groove 59. Continue to move downward, so that the telescopic rod 58 can be squeezed out of the telescopic slot 56, so that the clamping and positioning plate 55 can be pushed, and the four clamping and positioning plates 55 move forward synchronously, so that the four sides of the plate-shaped power accessory can be clamped at the same time, not only to achieve its clamping and fixing, but also to achieve its positioning adjustment through the squeezing of the clamping force, when the stamping plate 71 moves downward with the rectangular frame 73, the surface of the plate-shaped power accessory can be stamped and flattened, and the stamping block 72 presses against the punching slot 53 to achieve punching processing; After the stamping of the parts in the positioning groove 51 on the upper surface of the station roller 4 is completed, the rectangular frame 73 is reset as the stamping shaft 78 rotates, and the station roller 4 also rotates once at this time, and the stamped parts are rotated to one side of the station roller 4, and the parts to be processed on the upper surface of the station roller 4 continue to be stamped. While the next stamping is being performed, as the stamping shaft 78 rotates, the power rod 88 is driven to rotate at a uniform speed in the circumferential direction, and the eccentric rod 87 can be pulled by the linkage shaft 89 to rotate in a fan shape, and the eccentric rod When 87 rotates in a fan shape, it can drive the driving shaft 85 to rotate forward and reverse, thereby causing the driving rod 86 to deflect forward and reverse. When it deflects counterclockwise when viewed from the side, it can drive the movable frame 82 to deflect counterclockwise, so that the suction cup of the vertical suction cup fixture 81 faces the surface of the station roller 4. By retracting the resetting telescopic shaft 84, the suction cup fixture 81 can be pushed to the surface of the accessory for adsorption. After taking the material, the suction cup fixture 81 is reset clockwise, and the accessory can be discharged, so that it can be placed on the upper surface of the feeding conveyor belt 2 for transmission; The reduction motor 96 realizes the uniform circumferential rotation of the punching shaft 78 through the bevel gear set, and the uniform circumferential rotation of the punching shaft 78 can drive the linkage shaft 89 to pull the driving shaft 85 of the material-taking mechanism 8 in forward and reverse directions, so that it can complete the material-taking and material-discharging actions. At the same time, when the punching shaft 78 rotates at a uniform speed, the transmission gear 92 rotates, which can drive the linkage gear 93 to rotate. When the dial wheel 94 on one side of the linkage gear 93 contacts the concave surface of the groove wheel 91, the station roller 4 does not rotate. When the dial roller 95 rotates into the slot of the groove wheel 91, it can pull the station roller 4 to rotate once, and complete the upper surface stamping, lower surface material feeding and one side material taking of the station roller 4 during the intermittent time of the groove wheel 91. Therefore, the groove wheel 91 of this set of equipment moves intermittently, and the stamping and picking and placing are linked, so that the processing of accessories is continuous.
