Description

Technical Field

[0002] Fitness equipment is often classified into two major categories: single-function and comprehensive multi-function according to the number of training functions. When assembling and installing, holes need to be pre-drilled to facilitate subsequent installation. For example, a punching machine tool for fitness equipment production and processing that is easy to position described in the patent with the patent publication number CN116944541B. Through the design of the trigger rod cooperating with the through groove, no other mechanical structure or manual positioning is required, which facilitates the operation of the device. The design of the positioning device makes the device not slip when punching holes on the arc surface, increasing the accuracy during punching.

[0003] However, when this device punches holes in the equipment, it only simply positions the equipment. Since the equipment is not fixed, when the equipment is placed on the processing table, the equipment may tilt, resulting in crooked holes, which in turn affects subsequent installation.

When the threaded rod 303 rotates, the slider 305 can drive the fixed sleeve 306 to slide. At the same time, when the slider 305 at the bottom of the fixed sleeve 306 slides in the first chute 301, it will play a limiting role, so that the fixed sleeve 306 will not rotate accordingly and there will be no shaking during sliding. One set of fixed sleeves 306 drives the clamping block 310 to move to the right, and the other set of fixed sleeves 306 drives the clamping block 310 to move to the left. When the two sets of clamping blocks move inward, they will gradually clamp the equipment. At this time, the clamping block 310 will drive the sliding rod 309 and the first rack 312 to move backward, so that the sliding rod 309 squeezes the first spring 308, and when the first rack 312 moves, it will drive the circular gear 311 to rotate. The rotation of the circular gear 311 will drive the second rack 314 and the pressing plate 315 to move downward. When the pressing plate 315 moves downward, it will push the inclined equipment so that the equipment is placed flat on the equipment drilling and processing table 1. At the same time, when the pressing plate 315 can no longer push, the second rack 314 will block the circular gear 311, and the circular gear 311 will block the first rack 312, so that the clamping block 310 stops moving. The equipment can be fixed on the equipment drilling and processing table 1 through the two sets of clamping blocks 310 and the two sets of pressing plates 315 for subsequent drilling with the drill bit 707. According to the size of the hole to be drilled, a drill bit 707 of the corresponding style is used. Insert the drill bit 707 into the connection groove 701 through the limiting block 703. When the position is appropriate, release the drill bit 707 so that the limiting block 703 is inserted into the limiting groove 702 to clamp the limiting block 703 on the first rotating block 615. Then, turn the fixing rod 705 through the top block 706 so that the fixing rod 705 passes through the threaded hole 704 and is threadedly connected to the first rotating block 615. Furthermore, the drill bit 707 can be fixed on the first rotating block 615 through the limiting block 703. Then start the first electric push rod 603 to drive the clamping block 604 to move downward, so that the clamping block 604 is inserted into the lower clamping groove 618 opened at the top of the first rotating block 615 through the fixing groove 606 and the upper clamping groove 609. Then start the second driving motor 602, so that the second driving motor 602 can drive the clamping block 604 to rotate through the first electric push rod 603. The clamping block 604 can drive the first rotating block 615 and the fixed drill bit 707 to rotate. Then drive the drill bit 707 to move downward through the robotic arm 2 so that it can drill the equipment. When the drilling is completed, start the first electric push rod 603 to drive the clamping block 604 to move into the fixing groove 606, and start the second driving motor 602 to drive the clamping block 604 to rotate through the first electric push rod 603, so that it drives the first gear 605 to rotate through the clamping block 604. When the first gear 605 rotates, it can drive the second gear 607 and the turntable 608 to rotate, so that the turntable 608 rotates 180 degrees.Move the lower card slot 618 opened at the top of its second rotating block 616 to below the fixed slot 606 and the upper card slot 609 so that they are at the same horizontal level. Then start the first electric push rod 603 to drive the clamping block 604 to move downward, so that the clamping block 604 is inserted into the lower card slot 618 opened at the top of the second rotating block 616 through the fixed slot 606 and the upper card slot 609. Then start the second driving motor 602, so that the second driving motor 602 can drive the clamping block 604 to rotate through the first electric push rod 603. The second rotating block 616 and the second electric push rod 801 can be driven to rotate through the clamping block 604. Then drive the second electric push rod 801 to move above the opened hole through the robotic arm 2. Start the second electric push rod 801 to drive the grinding head 802 and the chamfering tool 803 to move downward. The sharp edge of the hole opening can be removed by the rotation of the chamfering tool 803, so that the burrs inside the hole can be cleaned up. Then polish the surface of the hole through the grinding head 802 to avoid being cut by burrs during use. The above is the working principle of this kind of punching machine tool for fitness equipment.
