Description

Technical Field

[0001] This invention relates to the field of bracket manufacturing equipment technology, and in particular to a bracket manufacturing tapping and forming machine tool. Background Technology

[0002] In the production of computer monitor stands, tapping is a crucial process for ensuring assembly accuracy and connection stability. Currently available stand tapping equipment generally suffers from numerous technical defects, making it difficult to meet the demands of large-scale, high-precision production. Traditional tapping equipment often employs a single-station design, requiring manual handling of each stand to the processing position and its positioning. This is not only labor-intensive but also suffers from low transport efficiency and large positioning deviations, easily leading to tapping position misalignment and affecting product yield. Furthermore, the positioning mechanisms of existing equipment are mostly unidirectional clamping, failing to achieve precise locking of the stand from all directions. This causes the stand to wobble during processing, further reducing tapping accuracy. In addition, traditional tapping devices often have fixed tapping heads. When processing different sizes of stands or threaded holes in different positions, the entire tapping assembly must be disassembled and replaced, a cumbersome and time-consuming process that severely impacts production continuity. Moreover, most equipment uses a single power source to control the movement drive mechanism, failing to achieve independent and precise movement of the positioning and tapping mechanisms, further restricting improvements in processing accuracy and efficiency. Therefore, developing a support tapping device that can achieve automated conveying, omnidirectional precise positioning, rapid tapping head replacement, and independent precise drive has become a pressing technical problem for the industry.

[0037] The invention is used as follows: It has a reasonable and simple structure, low production cost, convenient installation, and complete functions. In use, several computer monitor stands are first placed sequentially on the conveyor belt 33 of the conveying device 3. Adjacent stands are separated by positioning blocks 36. The motor 34 is started, and its output shaft drives a roller 35 fixedly connected to it to rotate. This roller 35 drives another roller 35 to rotate synchronously via the conveyor belt 33. The conveyor belt 33 begins to transport the stands along the longitudinal groove 32. During transport, the guide block 37 guides and limits the stands on the left side, while the upper pressure block 39 limits the stands on the upper side, ensuring the stands are smoothly transported to the corresponding position on the left side of the positioning and locking device 4. When the stands reach the designated position, the motor 34 stops operating, the conveyor belt 33 stops transporting, and the motor 29 of the two-position moving device 2 is started. The output shaft of motor 29 synchronously drives screw 23 to rotate. Screw 23 drives moving seat 24 to move to the left along guide groove 22 through threaded engagement. Positioning locking device 4, which is fixedly connected to moving seat 24, moves to the left along with it until the right side of the bracket enters the housing 42. Then, the drive cylinder 413 and drive cylinder 418 of the bidirectional drive device 41 are activated: the piston rod of drive cylinder 413 pushes connecting plate 412 down. Connecting plate 412 drives piston 416 down in oil chamber 417 through connecting column 415. The hydraulic oil in oil chamber 417 is transported to the execution cylinder 431 of the upper and lower clamping and positioning structures 45 through oil pipe 44. The piston rod of execution cylinder 431 extends and pushes clamping block 435 to move inward along groove 432 to clamp and position the upper and lower sides of the bracket (tension spring 433 is stretched and stored).Simultaneously, the piston rod of the second drive cylinder 418 pushes the connecting plate 419 downward. The connecting plate 419, through the connecting column 4110, drives the piston 4111 to move downward within the oil chamber 4112. The hydraulic oil in the oil chamber 4112 is transported through the oil pipe 46 to the actuator cylinders 431 of the left and right clamping and positioning structures 43. The piston rods of the actuator cylinders 431 extend, pushing the clamping block 435 to move inward along the groove 432, clamping and positioning the left and right sides of the bracket, ultimately achieving precise positioning and locking of the bracket in all directions. After the bracket is positioned and locked, the motor 56 of the replaceable tapping device 5 is started. The output shaft of the motor 56 drives the transmission shaft 55 to rotate. The transmission shaft 55 passes through... The connecting chuck 54 drives the connecting groove 518 of the multi-position tapping head 51 and the second transmission shaft 512 to rotate. The driving gear 517 on the left side of the second transmission shaft 512 rotates synchronously. The driving gear 517 drives the multiple driven gears 513 meshing with it to rotate. The driven gears 513 drive the corresponding third transmission shaft 514 to rotate, thereby causing the tap 516 fixed to the drill chuck 515 on the left side of the third transmission shaft 514 to rotate synchronously. Then, the second motor 28 of the two-position moving device 2 is started. The output shaft of the second motor 28 drives the second screw 26 to rotate. The second screw 26 drives the second moving seat 25 to move to the left along the guide groove 22 through the threaded engagement. The replaceable tapping device 5, which is fixedly connected to the second moving seat 25, moves to the left along with it. The rotating tap 516 gradually approaches and penetrates the preset position on the right end of the support, completing the tapping process. During the tapping process, the two moving devices 2, through the precise control of motor 1 29 and motor 2 28, ensure the relative position stability of the positioning locking device 4 and the replaceable tapping device 5, guaranteeing tapping accuracy. After tapping is completed, motor 2 28 rotates in reverse, driving the replaceable tapping device 5 to move to the right and reset. Motor 4 56 stops rotating, and tap 516 stops rotating. Subsequently, the piston rods of the drive cylinders 1 413 and 2 418 of the bidirectional drive device 41 retract in the reverse direction, and pistons 1 416 and 2 4111 reset. The actuator cylinders 431 of the clamping and positioning structure 1 43 and clamping and positioning structure 2 45 are activated. Without hydraulic oil input, the tension spring 433 retracts and resets, causing the clamping block 435 to move and release the clamping lock on the bracket. Motor 29 reverses its rotation, causing the positioning locking device 4 to move to the right and reset. Finally, motor 34 restarts, and the conveyor belt 33 continues to transport the next bracket to the designated station, repeating the above positioning and tapping process. If different specifications of brackets or threaded holes in different positions need to be processed, the spring pin 52 can be pulled to release its fixation on the multi-position tapping head 51. The original multi-position tapping head 51 can be removed from the slot 53, and a suitable multi-position tapping head 51 can be replaced. After replacing it with a suitable multi-position tapping head 51, the spring pin 52 can be released to allow it to engage with the corresponding slot of the new multi-position tapping head 51, completing the quick replacement and allowing subsequent processing.
