Description

TECHNICAL FIELD

[0001] The present application relates to the field of automatic deburring equipment, in particular to a wood disc piece automatic deburring device. BACKGROUND

[0002] With the increasing demand for power cables, the demand for wood discs for cable reels is also increasing. After the wood disc piece is formed, burrs will be left. During the assembly of the disc pieces and the operation of the disc assembly, accidents may occur due to the burrs, such as the hands of workers being cut, and the cables being scratched by the burrs, which is a considerable consumption of manpower and material resources. Therefore, deburring treatment must be performed. Some existing technologies can achieve automatic deburring operation. The existing technology includes a workbench, a base, a mechanical hand, a motor, a fixed block, a cutter bar, and a workpiece fixing device for fixing a workpiece to be deburred. The base is fixed on the workbench, the mechanical hand is fixed on the base, a lifting rod is arranged on the mechanical hand, the outer end of the lifting rod is connected with the fixed block, the motor is arranged on the fixed block, one end of the cutter bar penetrates through the fixed block and is connected with the working shaft of the motor, the other end of the cutter bar is provided with a brush head mounting rod, and the outer end of the brush head mounting rod is provided with a deburring brush head. The deburring brush head is moved by the mechanical hand to achieve deburring of the workpiece.

[0003] However, the existing deburring robot can only remove the burrs on the surface and the side of the wood disc piece. Due to the special structure of the wood disc piece, such as the through hole in the middle of the wood disc piece and the distribution of the roller blocking hole, screw hole and threading hole on the surface of the wood disc piece, the deburring robot needs to deburr not only the surface and the side of the wood disc piece, but also the inner end face of the through hole, roller blocking hole, screw hole and mounting hole on the wood disc piece. Since the position of the wood disc piece placed on the workbench is not fixed, the existing deburring robot cannot identify the position of the through hole, roller blocking hole, screw hole and mounting hole on the wood disc piece, and thus it is difficult to remove the burrs therein.

[0004] In view of the above-mentioned related technology, during the automatic deburring operation of the wood disc piece, the wood disc piece needs to be positioned during feeding to keep the fed wood disc piece at the same position, so that the mechanical hand can achieve the deburring operation of the wood disc piece through repeated actions. Therefore, there is an urgent need for an automatic deburring device capable of positioning the wood disc piece. SUMMARY

[0005] In order to solve the problem that the existing wood disc piece cannot be positioned during feeding in the prior art, thereby reducing the deburring efficiency and the deburring effect, the present application provides a wood disc piece automatic deburring device.

[0006] The wood disc piece automatic deburring device provided by the present application adopts the following technical solution:

[0007] The wood disc automatic deburring device comprises a workbench assembly for carrying materials, an up-down feeding assembly arranged on one side of the workbench assembly for feeding and discharging the workbench assembly, and a deburring assembly arranged on the other side of the workbench assembly for deburring and polishing the materials;

[0008] The workbench assembly comprises a workbench supported by a frame, a centering assembly arranged in the center of the workbench, the centering assembly comprising a conical shaft core penetrating the center of the workbench, a lifting and rotating mechanism connected below the shaft core to drive the shaft core to reciprocatingly lift and lower and protrude from the upper surface of the workbench, and the lifting and rotating mechanism also driving the shaft core to freely rotate;

[0009] At least two guide assemblies are symmetrically arranged on both sides of the centering assembly on the workbench, the guide assemblies comprising conical guide blocks reciprocatingly lifting and lowering and protruding from the upper surface of the workbench, and a sensor arranged in the middle of the upper end surface of the guide block;

[0010] A plurality of limiting assemblies are uniformly and circumferentially arranged at the bottom of the workbench, the limiting assemblies comprising limiting pins reciprocatingly lifting and lowering inside the workbench and protruding from the upper surface of the workbench, and a limiting pin lifting cylinder connected below the limiting pin to drive the limiting pin to reciprocatingly lift and lower;

[0011] At least two groups of travel switches are symmetrically arranged at the center of the edge of the bottom surface of the workbench, and the working end of the travel switch penetrates and protrudes from the upper surface of the workbench in the non-triggered state.

[0012] By adopting the technical scheme, the wood disc piece is grabbed and placed on the workbench in the workbench assembly by the feeding and discharging assembly. If the wood disc piece is correctly positioned on the workbench, the two ends of the wood disc piece are in contact with the working ends of the two travel switches, and the two travel switches are triggered at the same time. At this time, it is determined that the wood disc piece is positioned on the workbench and is correctly positioned. The lifting and rotating mechanism is started. The driving shaft core of the lifting and rotating mechanism moves upward. The shaft core enters the through hole in the center of the wood disc piece. Since the shaft core is conical, the wood disc piece is centered during the upward lifting of the wood disc piece by the shaft core. The shaft core drives the wood disc piece to rotate to a set height. When the blocking roller hole on the wood disc piece rotates to above the guide assembly, the sensor in the guide assembly senses the blocking roller hole. The guide assembly is started. The guide block moves upward and protrudes from the surface of the workbench to enter the blocking roller hole of the wood disc piece. Since the guide block is also conical, the guide block entering the blocking roller hole adjusts the position of the wood disc piece again, so that the wood disc piece is adjusted to a set position. At the same time, the limit pin lifting cylinder drives the limit pin to move upward into the screw hole on the wood disc piece. Then the shaft core and the guide block are lowered at the same time, so that the wood disc piece is lowered to the surface of the workbench, and the limit pin remains in the screw hole of the wood disc piece to limit the entire wood disc piece. Then the deburring assembly is started. The upper surface, side surface, middle through hole, blocking roller hole, screw hole and threading hole inside the wood disc piece are polished and deburred according to the set polishing track. After the work is completed, the limit pin is reset under the drive of the limit pin lifting cylinder. The feeding and discharging assembly takes out the polished wood disc piece, and the above operation is repeated. When the wood disc piece enters the workbench, if only one of the two travel switches is triggered, the position of the wood disc piece is incorrect. At this time, the middle through hole of the wood disc piece does not correspond to the centering assembly, and the shaft core in the centering assembly cannot enter the center through hole of the wood disc piece.

[0051] The implementation principle of the wood disc automatic deburring device in the embodiment is as follows: when deburring is performed, an operator places stacked wood disc materials in the feeding warehouse 4 on one side of the workbench assembly 2 and then starts the equipment. First, the feeding and discharging assembly 1 is started. The feeding and discharging assembly 1 places the wood disc on the workbench in the workbench assembly 1. When the feeding and discharging assembly 1 performs feeding and discharging, the lifting plate 43 moves up and down along the transverse plate 42, the transverse plate 42 reciprocates along the support 44, thereby driving the vacuum suction cup 50 to move freely along the X axis and the Y axis, the wood disc is fed and discharged by the vacuum suction cup 50, and the thin cylinder 48 is used to press down the vacuum suction cup, so that the vacuum suction cup 50 is tightly attached to the wood disc, and the adsorption effect of the vacuum suction cup 50 is improved;

[0052] When the wood disc enters the workbench 7 and is in the correct position, the two ends of the wood disc are in contact with the working ends of the travel switches 13, and the two travel switches 13 are triggered at the same time. At this time, it is determined that the wood disc is on the workbench and in the correct position, and the lifting and rotating mechanism 9 is started. The driving shaft core 36 of the lifting and rotating mechanism 9 moves upward. When the lifting and rotating mechanism 9 operates, the lifting cylinder 29 is first started, and the lifting cylinder 29 drives the lifting shaft 27 to move upward along the shaft sleeve 31. The lifting shaft 27 lifts the shaft core 36 upward, and the shaft core 36 enters the through hole in the center of the wood disc. Since the shaft core 36 is conical, the wood disc is centered during the lifting process of the shaft core 36. After the shaft core 36 lifts the wood disc to the set height, the wood disc is driven to rotate. The gear 26 on the lifting shaft 27 also moves upward during the upward movement of the lifting shaft 27. Since the gear 26 is engaged with the gear shaft 28, the gear 26 is always engaged with the gear shaft 28 during the lifting process. Therefore, when rotating, the rotating drive motor 30 drives the gear shaft 28 to rotate. The gear shaft 28 is engaged with the gear 26, thereby driving the lifting shaft 27 to rotate through the gear 26. During the upward lifting of the shaft core 36 in the centering assembly 6, the ball bearing lifting cylinder 38 in the rotating auxiliary assembly 8 is started synchronously. The piston rod in the ball bearing lifting cylinder 38 moves upward, driving the ball bearing 37 to move upward and contact the bottom surface of the wood disc, thereby supporting the edge of the wood disc. At the same time, when the wood disc is rotated by the centering assembly 6, the ball bearing 37 assists the wood disc in rotating. When the blocking roller hole on the wood disc rotates above the guide assembly 12, the sensor 33 in the guide assembly 12 senses the blocking roller hole, and the guide assembly 12 is started. The guide block lifting cylinder 35 drives the guide block 32 to move upward and protrude from the surface of the workbench 7 into the blocking roller hole of the wood disc. Since the guide block 32 is also conical, the guide block 32 enters the blocking roller hole to adjust the position of the wood disc again, so that the wood disc is adjusted to the set position. At the same time, the limit pin lifting cylinder 40 drives the limit pin 39 to move upward into the screw hole on the wood disc. Then the shaft core 36 and the guide block 32 descend at the same time. When the centering assembly 6 descends and resets, the ball bearing lifting cylinder 38 drives the ball bearing 37 to descend and reset synchronously, so that the wood disc descends to the surface of the workbench, and the limit pin 39 remains in the screw hole of the wood disc to limit the entire wood disc. Then the deburring assembly 3 is started. The mechanical hand drives the polishing and deburring device to polish and deburr the upper surface, side surface, middle through hole, blocking roller hole, screw hole, and threading hole inside the wood disc according to the set polishing track. After the work is completed, the limit pin 39 is reset under the drive of the limit pin lifting cylinder 40. The feeding and discharging assembly 1 takes the polished wood disc and places it in the discharging warehouse 5. Then the vacuum suction cup 50 is driven to move above the feeding warehouse 4 to repeat the above operation. When the wood disc enters the workbench, if only one of the two travel switches 13 is triggered, the position of the wood disc is incorrect. At this time, the middle through hole of the wood disc does not correspond to the position of the centering assembly 6, and the shaft core 36 in the centering assembly 6 cannot enter the center through hole of the wood disc.The operator needs to reposition the wood disc.

[0053] Embodiment two:

[0054] With reference to Figure 2 The difference between this embodiment and embodiment one is that when the wood disc deburring device is limited by the site and cannot use a mechanical hand with a long stroke, a reciprocating translation assembly 11 that drives the workbench to reciprocate and translate to one side of the deburring assembly 3 is arranged at the bottom of the workbench 7. Specifically, the reciprocating translation assembly 11 includes a base 19, two horizontal sliding rails 23 are arranged in parallel on the two sides of the base 19, the frame 10 is in sliding connection with the two horizontal sliding rails 23, a lead screw 17 is arranged above the base 19, the lead screw 17 is in rotary connection with the base 19 through a fixed seat 18 at both ends, a connecting seat 16 that is in threaded connection with the lead screw 17 is arranged in the middle of the frame 10, a driven wheel 15 is connected to one end of the lead screw 17, a translation driving motor 22 is arranged on one side of the base 19, a driving wheel 21 is connected to the output shaft of the translation driving motor 22, and the driving wheel 21 is in transmission connection with the driven wheel 15 through a transmission belt 20.

[0055] The implementation principle of the wood disc automatic deburring device in this embodiment is that when the movement stroke of the deburring assembly 3 is long and can perform circumferential movement around the entire edge of the wood disc, the reciprocating translation assembly 11 does not need to be arranged, and when the movement stroke of the deburring assembly 3 is short and the maximum stroke can only move to the middle position of the wood disc, the reciprocating translation assembly 11 is arranged. After the deburring assembly 3 polishes one half of the wood disc, the translation driving motor 22 in the reciprocating translation assembly 11 is started, the translation driving motor 22 drives the lead screw 17 to rotate through the driving wheel 21, the transmission belt 20 and the driven wheel 15, the lead screw 17 is in threaded connection with the connecting seat 16 on the frame 10, so as to drive the frame 10 to move along the horizontal sliding rail 23 to one side of the deburring assembly 3, so that the deburring assembly 3 can polish the other half of the wood disc.

[0056] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, so that: any equivalent changes made on the structure, shape and principle of the present application should be covered within the protection scope of the present application.
