Description

Technical Field

[0001] The present invention relates to the technical field of processing equipment, and in particular to a punching device, specifically a screw nut punching processing device. Background Art

[0002] At present, with the rapid development of industry, various transmission structures have been widely used, including screw transmission structures, and the screw nut is an indispensable part of the screw transmission structure. As a component connected to the screw, the screw nut exists as a connector between the screw and the fixed end, so the smoothness of movement between itself and the screw needs to be considered, so the screw nut needs to have oil nozzle holes and sealing holes. Traditional screw nut oil nozzle holes and sealing holes are processed separately for the screw nut. This processing efficiency is very low and the processing consistency is poor, and the yield rate cannot be guaranteed. Now we need a screw nut punching equipment that can punch holes in large quantities with good consistency. Summary of the invention

[0003] The present invention aims to solve the problems existing in the above-mentioned prior art and provide a screw nut punching processing equipment to solve the current problems of low efficiency and poor processing consistency in drilling oil nozzle holes and sealing holes in screw nuts, and meet the needs of large-scale, high-quality and efficient punching of screw nuts.

[0004] The technical solution adopted by the present invention to solve its technical problems is as follows: this screw nut punching processing equipment includes a frame, a horizontal turntable rotating along the center is rotatably connected to the frame, and positioning seats for automatically clamping and positioning screw nuts corresponding to the working process are evenly distributed on the circumference of the horizontal turntable. The frame surrounds the horizontal turntable in order of processing procedures, including a feeding robot, a flange hole punching device, a first sealing ring hole punching device, a first sealing ring hole tapping device, a flipping robot, a second sealing ring hole punching device, a second sealing ring hole tapping device, a nozzle hole punching device, a nozzle hole tapping device and a discharging robot. The flange hole punching device is composed of a group of flange hole machines that punch flange holes in pairs vertically and synchronously.

[0005] The first sealing ring hole punching device includes a first front sealing hole machine and a first rear sealing hole machine that punch the front section and the rear section respectively horizontally, and the first front sealing hole machine and the first rear sealing hole machine form the first front section sealing hole and the first rear section sealing hole respectively, and the first sealing ring hole tapping device includes a first front sealing hole tapping machine and a first rear sealing hole tapping machine that tap the front section sealing hole and the rear section sealing hole respectively; after the flipping manipulator flips, the second sealing ring hole punching device includes a second front sealing hole machine and a second rear sealing hole machine that punch the front section and the rear section respectively horizontally, and the second front sealing hole The machine and the second rear sealing hole machine correspond to form a second front section sealing hole and a second rear section sealing hole respectively, and the second sealing ring hole tapping device includes a second front sealing hole tapping machine and a second rear sealing hole tapping machine for tapping the front section sealing hole and the rear section sealing hole respectively; considering the length of the sealing holes on both sides, directly drilling and then tapping operations will greatly increase the probability of drill bit wear and greatly increase the processing cost, while drilling and tapping the sealing holes in front and back sections can effectively solve the problem of drill bit wear, reduce unnecessary wear of the drill bit and extend its service life.

[0006] The flip robot is used to rotate the screw nut horizontally by 180 degrees so that in subsequent processing, the processing surface is respectively aligned with the second sealing ring hole punching device, the second sealing ring hole tapping device, the oil nozzle hole punching device, and the oil nozzle hole tapping device.

[0007] The nozzle hole drilling device is a nozzle hole drilling machine for drilling the nozzle hole horizontally, and the nozzle hole tapping device is a nozzle hole tapping machine for tapping the nozzle hole.

[0008] The various workstations of the feeding robot 4, the flange hole punching device, the first sealing ring hole punching device, the first sealing ring hole tapping device, the flip robot 5, the second sealing ring hole punching device, the second sealing ring hole tapping device, the oil nozzle hole punching device, the oil nozzle hole tapping device and the discharging robot 6 start working at the same time. Compared with processing a single part one by one, the work efficiency is significantly improved, and unnecessary workstation devices or mechanisms can be closed individually according to processing requirements, thereby achieving the effect of improving efficiency while saving energy and reducing emissions.

[0009] A processing technology using the above-mentioned screw nut drilling processing equipment, the steps are:

[0010] A: The feeding robot grabs the unprocessed screw nut and places it at the designated position. At this time, the positioning seat rotates to clamp the screw nut, and the horizontal turntable starts to rotate;

[0011] B: When the positioning seat with the screw nut rotates to the bottom of the flange hole machine, it stops, and the flange hole machine starts to drill the flange holes vertically. Repeat the above actions until all the flange holes are drilled by the screw nut;

[0012] C: After the flange hole is completed, the positioning seat rotates to the bottom of the first sealing ring hole punching device. At this time, the first front sealing hole machine and the first rear sealing hole machine punch the first front section sealing hole and the first rear section sealing hole in turn. The first front section sealing hole and the first rear section sealing hole are combined into a sealing hole in a front and rear section relationship;

[0013] D: The positioning seat continues to rotate, and the first front sealing hole tapping machine and the first rear sealing hole tapping machine successively perform segmented tapping on the first front sealing hole and the first rear sealing hole;

[0014] E: The positioning seat rotates to the bottom of the flip robot, the positioning seat loosens the screw nut and the flip robot horizontally rotates the screw nut 180° to keep it stationary, the positioning seat clamps and holds it tightly, and then the flip robot loosens and resets;

[0015] F: Similar to the CD process, the second front sealing hole machine and the second rear sealing hole machine successively drill the second front section sealing hole and the second rear section sealing hole on the opposite side end surface, the second front section sealing hole and the second rear section sealing hole are combined into a sealing hole in a front and rear section relationship, and the second front sealing hole tapping machine and the second rear sealing hole tapping machine successively perform segmented tapping on the second front section sealing hole and the second rear section sealing hole;

[0016] G: After the positioning seat reaches the position of the nozzle hole machine, the nozzle hole is drilled, and the nozzle hole is tapped by the nozzle hole tapping machine;

[0017] H: After the nozzle hole is completed, the positioning seat rotates to the discharging position, the positioning seat loosens the screw nut and the discharging manipulator grabs the processed screw nut to discharging;

[0018] I: Repeat the above steps AH to complete the batch screw nut drilling operation.

[0019] A further improvement of the present invention is that a first puncher for expanding the first front-section sealing hole is fixed on the frame between the first sealing ring hole punching device and the first sealing ring hole tapping device, and the drill bit diameter of the first puncher is larger than the drill bit diameter of the first front-section sealing hole machine. A second puncher for expanding the second front-section sealing hole is fixed on the frame between the second sealing ring hole punching device and the second sealing ring hole tapping device, and the drill bit diameter of the second puncher is larger than the drill bit diameter of the second front-section sealing hole machine. With this arrangement, expansion is performed on the basis of the first front-section sealing hole and the second front-section sealing hole that have been previously punched, and the first front-section sealing hole and the second front-section sealing hole that are obtained after expansion are then tapped, which greatly reduces the difficulty of tapping the front section, and also provides convenient conditions for tapping the back section, thereby reducing the difficulty of tapping as a whole.

[0020] According to a further improvement of the present invention, the flange hole machine has a double drill bit structure, and the position of the flange hole machine is symmetrically arranged on the diameter according to the center of the screw nut. After such arrangement, the flange hole machine can quickly drill holes in pairs, ensuring the precise position between the paired holes, and reducing the error caused by individual drilling.

[0021] In a further improvement of the present invention, a driving motor with a speed reduction mechanism is fixed in the frame, and the driving motor is meshed with the horizontal turntable through a gear structure. Considering the requirements for the accuracy of the punching position, the rotation accuracy of the horizontal turntable needs to be guaranteed, and the driving motor with the gear meshing transmission can effectively meet the requirements of accurate rotation, ensuring that the punching position meets the requirements.

[0022] A further improvement of the present invention is that the feeding manipulator, the flipping manipulator and the discharging manipulator are all provided with air outlets for blowing away foreign matter. The air outlets move with the front end of the manipulator to face the clamping part of the positioning seat, and the air outlets are connected to the air pump. Considering that punching will produce fine particles, which are very likely to float into the clamping part of the positioning seat, the air outlet connected to the air pump is used to blow air into the clamping part of the positioning seat to blow away the particles in the clamping part of the positioning seat, thereby ensuring the accuracy of the clamping position and thus making the punching position meet the accuracy requirements.

[0023] A further improvement of the present invention is that an air slip ring is provided in the rotating shaft of the horizontal turntable, one end of the air slip ring is connected to the air pump as a fixed input end, and the other end is a rotating multi-branch output end connected to each positioning seat to form a complete air path. The air slip ring can be used to branch the air pump into multiple paths and connect them to the positioning seat, and after the horizontal turntable rotates, the air pipes also rotate synchronously without interference and entanglement, ensuring the normal operation of the positioning seat.

[0024] The beneficial effects of the present invention are as follows: the structure of the present invention is reasonable and compact, and the positioning seat is driven by the horizontal turntable to pass through the feeding robot, the flange hole punching device, the first sealing ring hole punching device, the first sealing ring hole tapping device, the flipping robot, the second sealing ring hole punching device, the second sealing ring hole tapping device, the oil nozzle hole punching device, the oil nozzle hole tapping device and the discharging robot in sequence, that is, after one circle, the entire punching process is completed, and the horizontal and vertical punching are completed at one time. Compared with the traditional single part punching processing, the processing efficiency is significantly improved, forming a large-scale processing and punching capability, the punching consistency is guaranteed, the use effect is good, and it is suitable for promotion.
