Description

Technical Field

[0001] This utility model relates to the field of resistance welding equipment technology, and in particular to an integrated machine for grinding and removing electrode caps. Background Technology

[0002] Currently, electrode caps are a type of welding electrode used in resistance welding equipment, such as fixed spot welding machines, suspended spot welding machines, and robotic spot welding machines. Because they are fitted onto the electrode connecting rod, they are called electrode caps.

[0003] After a period of use, the surface of the electrode cap will be oxidized or have impurities adhering to it, affecting the quality of the solder joint. Therefore, it is necessary to grind the surface of the electrode cap. When the electrode cap is close to its service life after multiple grindings, it is necessary to remove the electrode cap. Grinding and replacing the electrode cap generally requires two types of equipment: an electrode cap grinder and an electrode cap removal device. These two types of equipment require at least two rotating motors, which results in excessive costs. In addition, the existing electrode cap removal equipment also has some defects.

[0004] For example, a Chinese patent application with application number 2020201265693 discloses a floating electrode cap replacement machine, including a replacement machine body and a floating mounting frame. The replacement machine body includes a housing, a cap removal head, a drive device, and a damper. The housing has a receiving cavity, and the cap removal head is movably placed in the receiving cavity. The cap removal head includes a cap removal gear, a claw cover, and several claws. The claw cover includes an upper cover and a lower cover, which are located on both sides of the cap removal gear and are fixedly connected together by a connecting pin. The cap removal gear is located between the upper cover and the lower cover and can rotate relative to the claw cover. The decapping gear is a ring structure with several claws placed circumferentially inside the inner ring of the decapping gear. The rear end of each claw is hinged to the inner wall of the decapping gear around the first axis. The front end of each claw has a forward-protruding longitudinal clamping blade. Each clamping blade forms a disassembly channel. Each clamping blade has a forward clamping part and a reverse clamping part on both sides. Each claw is also hinged to the claw cover by a positioning pin. Each connecting pin, positioning pin and the first axis are parallel to the axis of the decapping gear. The housing and the claw cover have through holes that connect the disassembly channel for the electrode cap to pass through.

[0005] The technical solution has a reasonable structure. However, it does not take into account that each rotation of the motor in the drive device drives several jaws to clamp the electrode cap. After the electrode cap separates from the welding gun, the motor needs to reverse to drive several jaws to release the electrode cap before it can be detached. Such frequent forward and reverse rotation of the motor will affect its service life. Therefore, we propose an integrated electrode cap grinding and removal machine. Summary of the Invention

The first cap-removing gear meshes with the second cap-removing gear and the first transmission gear in the grinding mechanism. Therefore, the first transmission gear also drives the hollow cylindrical mounting base to rotate. The electrode cap is ground by the grinding component on the hollow cylindrical mounting base. The second cap-removing gear rotates in the opposite direction to the first cap-removing gear. Since the upper cap-removing component and the lower cap-removing component have the same structure, the effect is also opposite when the rotation direction of the second cap-removing gear is opposite to that of the first cap-removing gear. When the upper cap-removing component clamps the electrode cap, the lower cap-removing component will disengage from the electrode cap. When the upper cap-removing component disengages from the electrode cap, the lower cap-removing component will clamp the electrode cap. Therefore, each reverse rotation of the rotating motor will have two effects: clamping the electrode cap and disengaging the electrode cap. This reduces the wear and tear on the service life of the rotating motor due to excessive forward and reverse rotation. Attached Figure Description

[0029] In this embodiment, the transmission component 202 includes a rotating column 202a disposed in the first mounting groove 102c and the fourth mounting groove 106b. A second transmission gear 202b and a helical gear 202c are spaced apart on the middle of the outer wall of the rotating column 202a. A first bearing 202d and a second bearing 202e are respectively disposed on the upper and lower parts of the outer wall of the rotating column 202a. The outer walls of the first bearing 202d and the second bearing 202e are respectively disposed on the inner walls of the fourth mounting groove 106b and the first mounting groove 102c. An involute cylindrical helical gear 201b is disposed at the end of the output shaft of the rotating motor 201a. The involute cylindrical helical gear 201b passes through the transmission hole 102b and meshes with the helical gear 202c. The second transmission gear 202b meshes with the first unloading gear 402.

[0030] When the PLC controller is turned on, the rotating motor 201a is activated. The involute cylindrical helical gear 201b at the output shaft end of the rotating motor 201a meshes with the helical gear 202c, and the second transmission gear 202b meshes with the first unloading gear 402. Therefore, the helical gear 202c drives the first unloading gear 402 to rotate through the second transmission gear 202b.

[0031] In this embodiment, a fixing seat 405 is fixed at the first cap removal hole 102f, the second cap removal hole 102g, the third cap removal hole 106d, and the fourth cap removal hole 106e. A through hole 405a is provided in the middle of the fixing seat 405, and an abutment surface 405b is provided on the inner wall of the fixing seat 405 corresponding to the through hole 405a. Both the upper cap removal assembly 401 and the lower cap removal assembly 403 include a symmetrically arranged upper pressure cover 406 and a lower pressure cover 407. Both the upper pressure cover 406 and the lower pressure cover 407 include a cover body a and a bottom edge located on the cover body a. The outer edge b, the middle of the cap body a is provided with a cap removal hole c, the two cap bodies a are respectively passed through the through hole 405a and fixed to each other, a number of rotating grooves d are provided circumferentially between the two cap bodies a, and a connecting shaft e is provided between two opposite rotating grooves d. A clamping block 408 is rotatably provided on the connecting shaft e. The first cap removal gear 402 is rotatably provided between the upper pressure cover 406 and the lower pressure cover 407 in the upper cap removal assembly 401, and the second cap removal gear 404 is rotatably provided between the upper pressure cover 406 and the lower pressure cover 407 in the lower cap removal assembly 403.

[0032] In this embodiment, the first cap removal gear 402 and the second cap removal gear 404 are both provided with a sleeve hole g in the middle, which is sleeved on the outer wall of the cap body a. The inner walls of the first cap removal gear 402 and the second cap removal gear 404 are provided with a drive groove h at a position corresponding to a plurality of clamping blocks 408. The clamping block 408 is provided with a swing part 408a on the side facing the drive groove h. The swing part 408a is located in the drive groove h. The inner side of the clamping block 408 is provided with a clamping surface 408b. The clamping surface 408b is provided with a serration 408c. The first cap removal gear 402 and the second transmission gear 202b mesh with each other.

[0033] When the electrode cap on the welding torch needs to be removed, insert the electrode cap from the top of the welding torch into the removal hole c of the upper pressure cover 406 in the upper removal assembly 401. When the first removal gear 402 rotates clockwise, the second removal gear 404 will rotate counterclockwise. The clockwise rotation of the first removal gear 402 will cause the swinging part 408a of the clamping block 408 to rotate clockwise around the connecting shaft e through the drive groove h, until the clamping surface 408b on the inner side of the clamping block 408 clamps the electrode cap. At this time, the first removal gear... As wheel 402 continues to rotate, it causes several clamping blocks 408 to clamp the electrode cap and rotate between the electrode cap and the welding torch. Lifting the welding torch upwards separates it from the electrode cap. Then, the electrode cap below the welding torch is inserted into the cap removal hole c of the lower cap removal assembly 403's lower pressure cover 407. The rotating motor 201a is controlled to reverse, causing the first cap removal gear 402 to rotate counterclockwise, which in turn causes the second cap removal gear 404 to rotate clockwise. The counterclockwise rotation of the first cap removal gear 402 causes the drive groove h to squeeze several... The swinging part 408a of the clamping block 408 rotates counterclockwise around the connecting shaft e and releases the electrode cap. The electrode cap naturally falls off in the cap removal hole c of the upper cap removal assembly 401 due to gravity. When the second cap removal gear 404 rotates clockwise, several clamping blocks 408 in the lower cap removal assembly 403 clamp the electrode cap as in the upper cap removal assembly 401. At this time, the welding torch is pressed down to disengage the electrode cap from the welding torch. If the rotating motor 201a reverses again, the lower cap removal assembly... The electrode cap in the cap removal hole c in 403 falls off naturally due to gravity, and the upper cap removal component 401 re-clamps the electrode cap that has entered the cap removal hole c. Therefore, each reverse rotation of the rotating motor 201a can achieve one clamping and one release of the electrode cap through the upper cap removal component 401 and the lower cap removal component 403 respectively. Compared with the prior art, in which the rotating motor 201a removes and releases the electrode cap by each forward and reverse rotation, this reduces the wear caused by the frequent forward and reverse rotation of the rotating motor 201a.

[0034] In this embodiment, the top shell 106 has a fifth mounting groove 106f on one side of the third cap removal hole 106d and the fourth cap removal hole 106e, respectively. A damper 409 is provided in the fifth mounting groove 106f. The damper 409 includes a mounting head 409a movably disposed in the fifth mounting groove 106f. A damping rod 409b is fixed on one side of the mounting head 409a. The damping rod 409b is radially disposed along the fixing seat 405, and one end of the damping rod 409b passes through the fixing seat 405 and abuts against the outer wall of the cover body a of the upper pressure cover 406. The other side of the mounting head 409a is fixedly connected to one end of the compression spring 409c. The other end of the compression spring 409c is fixed to the inner wall of the fifth mounting groove 106f.

[0035] The damping rod 409b, under the elastic force of the compression spring 409c, abuts against the outer wall of the cover body a of the upper cap 406 in the upper cap removal assembly 401 and the lower cap removal assembly 403. During the process of the clamping block 408 being rotated under force until it clamps the electrode cap, the cover body a of the upper cap 406 is kept from rotating. After several clamping blocks 408 clamp the electrode cap, the upper cap 406 and the lower cap 407 are driven to rotate simultaneously.

[0036] In this embodiment, the upper housing 102 is provided with a first mounting ring 304 around the first grinding hole 102e, the top housing 106 is provided with a second mounting ring 305 around the second grinding hole 106c, and the hollow cylindrical mounting base 301 is provided with a third bearing 305a and a fourth bearing 304a distributed on the upper and lower parts of the first transmission gear 302. The outer walls of the third bearing 305a and the fourth bearing 304a are respectively fixed to the second mounting ring 305 and the first mounting ring. The inner wall of 304, the grinding assembly 303 includes two tool holders 303a respectively set at the upper and lower openings of the hollow cylindrical mounting base 301. The two tool holders 303a have through slots 303b on both sides. The middle part of the two tool holders 303a is recessed to form a fan-shaped platform 303c. The side of the fan-shaped platform 303c is recessed to form a locking groove 303d. A tool 303e is fixed in the locking groove 303d. The tool 303e has arc-shaped cutting surfaces 303e-1 symmetrically arranged on the upper and lower sides.

[0037] Regardless of whether the first cap removal gear 402 rotates forward or backward, it can drive the rotation of the hollow cylindrical mounting base 301 through the first transmission gear 302. When the electrode cap on the welding torch needs to be re-grinded, the electrode cap can be inserted into the fan-shaped platform 303c in the middle of the tool holder 303a. The tool 303e in the side retaining groove 303d of the fan-shaped platform 303c can perform re-grinding operations on the electrode cap.

[0038] In this embodiment, the first connecting member 3 includes a connecting plate 3a and a clamp 3b. The connecting plate 3a is located on the back of the control box 2, and the clamp 3b is located on one side of the outer wall of the column 1. Threaded posts 3c are provided at both ends of the clamp 3b. The threaded posts 3c pass through the connecting plate 3a and are threadedly connected to the nut 3d.

[0039] In this embodiment, the second connector 104 includes a first clamping block 104a and a second clamping block 104b clamped on both sides of the column 1. The first clamping block 104a has threaded holes 104c on both sides, and the second clamping block 104b has connecting holes 104d on both sides. The first clamping block 104a and the second clamping block 104b are connected by bolts 104e, and the bolts 104e pass through the connecting holes 104d and are threadedly connected to the threaded holes 104c.

[0040] Working principle: The PLC controller starts the rotating motor 201a. The involute cylindrical helical gear 201b at the output shaft end of the rotating motor 201a meshes with the helical gear 202c. The second transmission gear 202b meshes with the first cap-removing gear 402. Therefore, the helical gear 202c drives the first cap-removing gear 402 to rotate via the second transmission gear 202b. Regardless of whether the first cap-removing gear 402 rotates forward or backward, it can drive the rotation of the hollow cylindrical mounting base 301 via the first transmission gear 302. When the electrode cap on the welding torch needs to be reground, the electrode cap can be inserted into the sector-shaped platform 303c in the middle of the tool holder 303a. The tool 30 is held in the slot 303d on the side of the sector-shaped platform 303c. 3e allows for the grinding of the electrode cap. When the electrode cap on the welding torch needs to be removed, the electrode cap above the welding torch is inserted into the removal hole c of the upper pressure cover 406 in the upper removal assembly 401. When the first removal gear 402 rotates clockwise, the second removal gear 404 rotates counterclockwise. The clockwise rotation of the first removal gear 402 will cause the swinging part 408a of the clamping block 408 to rotate clockwise around the connecting shaft e through the drive groove h, until the clamping surface 408b on the inner side of the clamping block 408 clamps the electrode cap. At this time, the continued rotation of the first removal gear 402 will drive several clamping blocks 408 to clamp the electrode cap and cause the electrode cap and the welding torch to rotate, and the welding torch will move upward. The electrode cap can be separated from the welding torch. The electrode cap below the welding torch is then inserted into the cap removal hole c of the lower cap removal assembly 403's lower pressure cover 407. The rotating motor 201a is reversed, causing the first cap removal gear 402 to rotate counter-clockwise, which in turn causes the second cap removal gear 404 to rotate clockwise. The counter-clockwise rotation of the first cap removal gear 402 causes the drive groove h to squeeze the swinging part 408a of several clamping blocks 408 around the connecting shaft e, causing it to rotate counter-clockwise and release the electrode cap. The electrode cap naturally falls out of the cap removal hole c of the upper cap removal assembly 401 due to gravity. When the second cap removal gear 404 rotates clockwise, the several clamping blocks 408 in the lower cap removal assembly 403 move as described above in the upper cap removal assembly 401. Several clamping blocks 408 typically hold the electrode cap. At this time, the welding torch is pressed down, causing the electrode cap to detach from the welding torch. If the rotating motor 201a reverses again, the electrode cap in the cap removal hole c of the lower cap removal assembly 403 will naturally fall off due to gravity. The upper cap removal assembly 401 will then re-clamp the electrode cap that has entered the cap removal hole c. Therefore, each reverse rotation of the rotating motor 201a can achieve one clamping and one detachment of the electrode cap through the upper cap removal assembly 401 and the lower cap removal assembly 403, respectively. Compared with the prior art, where the rotating motor 201a removes and detaches the electrode cap by each forward and reverse rotation, this reduces the wear and tear caused by the frequent forward and reverse rotation of the rotating motor 201a.
