Technical Field

[0001] This utility model relates to the field of tapping equipment technology, and in particular to an automatic tapping equipment for metal parts. Background Technology

[0002] Automatic tapping equipment for metal parts is a type of mechanical equipment used to automatically complete the internal threading of metal parts. It utilizes high-precision tapping tools and automated operation to tap the threaded holes of metal parts, and is widely used in industries such as machinery manufacturing, automotive, electronics, and aerospace.

[0003] Existing technologies, such as the utility model patent with publication number CN216575932U, disclose a tapping device, including a main frame and a clamping device. A worktable is fixedly connected to the upper surface of the main frame, and a collection box is disposed below the main frame. A placement platform is fixedly connected to the upper surface of the worktable, and a rotator is disposed on the upper surface of the worktable. The clamping device is disposed on the surface of the placement platform, and includes a clamping block and a rotating rod. The clamping block is slidably connected to the inner wall of the placement platform, and the rotating rod is rotatably connected to the inner wall of the clamping block. A slot is formed on the upper surface of the rotating rod, and a groove is formed on the lower surface of the rotating rod. A locking rod is slidably connected to the inner wall of the placement platform, and the locking rod engages with the inner wall of the slot on the upper surface of the rotating rod. This application, by setting up a clamping device, effectively stabilizes the material during operation, reduces the probability of material shaking during equipment operation, simplifies the use of the equipment, and improves the user's work efficiency.

[0004] During the process of automatically tapping metal parts using tapping equipment, it was found that when tapping metal parts, it is usually necessary to clamp and fix a variety of metal parts of different sizes. Since most of the positioning fixtures in the existing technology have a relatively single clamping size, they are mostly used to clamp and fix a specific and single metal part. When it is necessary to clamp and fix metal parts of different sizes, it is necessary to frequently change and install clamping fixtures of different sizes, which leads to the problem of inconvenience and slow tapping of metal parts. Utility Model Content

[0005] The purpose of this invention is to solve the problem that in the prior art, when tapping metal parts, it is usually necessary to clamp and fix a variety of metal parts of different sizes. Since most of the positioning fixtures in the prior art have relatively simple clamping dimensions, they are mostly used to clamp and fix a specific and single metal part. When it is necessary to clamp and fix metal parts of different sizes, it is necessary to frequently change and install clamping fixtures of different sizes, which makes it inconvenient to quickly tap metal parts.

[0006] To solve the above technical problems, this utility model provides an automatic tapping device for metal parts, comprising: a base plate, a tapping head, and an auxiliary device. A tapping machine is fixedly connected to one side of the base plate, and a control box is fixedly connected to one side of the tapping machine. The tapping head is fixedly connected to the tapping machine via the auxiliary device. A clamping device is provided on the surface of the base plate corresponding to the position of the tapping head. The clamping device includes a carrying plate, the lower surface of which is fixedly connected to the base plate. A carrying groove is formed on the surface of the carrying plate corresponding to the position of the tapping head. Two support blocks are fixedly connected to the upper surface of the carrying plate. The inner walls of the two support blocks are rotatably penetrated by the same threaded rod. The arc surface of the threaded rod is threaded... A movable block is attached, with its lower surface abutting against the surface of a carrying plate. Connecting seats are fixedly connected to both sides of the movable block. A connecting arm is rotatably connected to the inner wall of each connecting seat, and a movable seat is rotatably connected to the other end of each connecting arm. A pressing rod is fixedly connected to one side of the movable seat, and a sliding block is fixedly connected to the lower surface of the pressing rod. A slide rail slides through the inner wall of the sliding block, and the lower surfaces of the two slide rails are fixedly connected to the same carrying plate. A sliding rod is fixedly connected to one end of the pressing rod, and a fixed block slides through the arc surface of the sliding rod. The lower surfaces of the two fixed blocks are fixedly connected to the same carrying plate, and a clamping block is fixedly connected to the other end of the pressing rod.

[0007] The effect achieved by the above components is as follows: When the tapping machine is tapping a metal part, and the metal part needs to be clamped and fixed first, the metal part is placed in the loading groove. Then, the screw is rotated, causing the screw to move away from the metal part along with the moving block. The connecting seat moves with the moving block, and the connecting arm rotates. Since the pressing rod can only move along the slide rail, the rotation of the connecting arm will cause the pressing rod to move, causing the pressing rod to move along the slide rail towards the metal part along with the sliding block. At the same time, the sliding rod also slides along the inner wall of the fixed block, and the two clamping blocks also move towards each other until the clamping blocks are in close contact with the metal part, achieving the function of clamping and fixing. Then, the tapping machine can be started through the control box to tap the metal part.

[0008] Preferably, a slider is fixedly connected to the lower surface of the movable block, and a groove is formed on the surface of the carrier plate corresponding to the position of the slider, and the inner wall of the groove is slidably connected to the surface of the slider.

[0009] The effect achieved by the above components is that the slider slides along the groove when the moving block moves, which plays a guiding role.

[0010] Preferably, one end of the lead screw is fixedly connected to a handle, and the arc surface of the handle is provided with several grooves.

[0011] The effect achieved by the above components is that the screw can be turned with the help of a handle, which makes it more convenient.

[0012] Preferably, an anti-slip pad, which is a rubber pad, is fixedly connected to one side of the clamping block.

[0013] The effect achieved by the above components is that the rubber pad has good friction, so the anti-slip pad can make the clamping block more secure when holding metal parts.

[0014] Preferably, the auxiliary device is located on one side of the tapping machine, and the position of the auxiliary device corresponds to the position of the tapping head. The auxiliary device includes a connecting cylinder and a connecting block. The upper surface of the connecting cylinder is fixedly connected to the tapping machine, and the lower surface of the connecting block is fixedly connected to the tapping head. The arc surface of the connecting block is inserted into the inner wall of the connecting cylinder. Guide blocks are fixedly connected to both sides of the connecting block. A guide groove is formed on the inner wall of the connecting cylinder corresponding to the position of the guide block. The inner wall of the guide groove is slidably connected to the guide block. A limit rod is threadedly connected inside the connecting cylinder corresponding to the position of the guide block. An insertion hole is formed on the surface of the guide block corresponding to the position of the limit rod. The inner wall of the insertion hole is threadedly connected to the limit rod.

[0015] The effect achieved by the above components is as follows: When the tapping head needs to be replaced after long-term use, first use a tool to rotate the limiting rod to move it away from the insertion hole until the limiting rod is no longer in contact with the insertion hole. Then move the old tapping head downwards and insert the connecting block on the new tapping head into the inner wall of the connecting cylinder. At the same time, the guide block on the connecting block slides along the guide groove until the connecting block abuts against the connecting cylinder. At this time, the insertion hole on the guide block is exactly aligned with the limiting rod. Then rotate the limiting rod in the opposite direction to insert it into the insertion hole. In this way, the tapping head is replaced.

[0016] Preferably, an auxiliary pad, which is a silicone pad, is fixedly connected to the arc surface of the guide block.

[0017] The effect achieved by the above components is that the silicone pad has good sliding properties, so the auxiliary pad can prevent the guide block from getting stuck when the connecting block is inserted into the inner wall of the connecting cylinder.

[0018] Preferably, the arc surface of the limiting rod is threadedly connected to a limiting ring, and the arc surfaces of the two limiting rings are fixedly connected to the same connecting cylinder.

[0019] The effect achieved by the above components is that the limiting ring can limit the position of the limiting rod when it rotates, preventing the limiting rod from deviating.

[0020] Compared with related technologies, the automatic tapping device for metal parts provided by this utility model has the following advantages:

[0021] This invention provides an automatic tapping device for metal parts. Before tapping a metal part using a tapping machine, the metal part needs to be clamped and fixed. First, the metal part is placed in the loading slot. Then, by rotating the screw with the handle, the screw moves the moving block away from the metal part. The slider also moves along the slide rail, and the connecting seat moves with the moving block. The connecting arm rotates, and since the pressing rod can only move along the slide rail, the rotation of the connecting arm causes the pressing rod to move, moving the pressing rod and the sliding block along the slide rail towards the metal part. Simultaneously, the sliding rod slides along the inner wall of the fixing block, and the two clamping blocks move closer to each other until they are tightly against the metal part, achieving the clamping and fixing effect. Then, the tapping machine is started via the control box to tap the metal part. Through the operation of the clamping device, the function of clamping and fixing the metal part is achieved.

[0022] When a tapping head needs replacement after prolonged use, first use a tool to rotate the limiting rod, moving it away from the insertion hole until it no longer contacts it. Then, move the old tapping head downwards and insert the connecting block of the new tapping head into the inner wall of the connecting cylinder. Simultaneously, slide the guide block on the connecting block along the guide groove until the connecting block abuts against the connecting cylinder. At this point, the insertion hole on the guide block should be aligned with the limiting rod. Then, rotate the limiting rod in the opposite direction to insert it into the insertion hole. This completes the tapping head replacement. By operating the auxiliary device, the tapping head replacement can be achieved. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0033] Please see Figures 1 to 7 The present invention provides an automatic tapping device for metal parts, comprising: a base plate 1, a tapping head 4 and an auxiliary device 6. A tapping machine 2 is fixedly connected to one side of the surface of the base plate 1, and a control box 3 is fixedly connected to one side of the tapping machine 2. The tapping head 4 is fixedly connected to the tapping machine 2 by means of the auxiliary device 6. A clamping device 5 is provided on the surface of the base plate 1 corresponding to the position of the tapping head 4.

[0034] In the embodiments of this utility model, please refer to Figures 1 to 4The clamping device 5 includes a carrying plate 501, the lower surface of which is fixedly connected to the base plate 1. A carrying groove 516 is formed on the surface of the carrying plate 501 corresponding to the position of the tapping head 4. Two support blocks 502 are fixedly connected to the upper surface of the carrying plate 501. A single lead screw 503 rotatably passes through the inner walls of the two support blocks 502. A moving block 506 is threaded onto the arc surface of the lead screw 503. The lower surface of the moving block 506 abuts against the surface of the carrying plate 501. Connecting seats 508 are fixedly connected to both sides of the moving block 506. Connecting arms 509 are rotatably connected to the inner walls of the connecting seats 508. The other end of the connecting arm 509 is rotatably connected to a movable seat 510. A pressing rod 511 is fixedly connected to one side of the movable seat 510. A sliding block 517 is fixedly connected to the lower surface of the pressing rod 511. A slide rail 518 slides through the inner wall of the sliding block 517. The lower surfaces of the two slide rails 518 are fixedly connected to the same carrying plate 501. A sliding rod 512 is fixedly connected to one end of the pressing rod 511. A fixing block 513 is slidably connected to the arc surface of the sliding rod 512. The lower surfaces of the two fixing blocks 513 are fixedly connected to the same carrying plate 501. A clamping block 514 is fixedly connected to the other end of the pressing rod 511. When tapping machine 2 taps a metal part, it needs to clamp and fix the metal part first. First, place the metal part in the loading groove 516, then rotate the lead screw 503, so that the lead screw 503 moves the moving block 506 away from the metal part. The connecting seat 508 moves with the moving block 506. The connecting arm 509 rotates. Since the pressing rod 511 can only move along the slide rail 518, the rotation of the connecting arm 509 will cause the pressing rod 511 to move. The pressing rod 511 moves the sliding block 517 along the slide rail 518 towards the metal part. At the same time, the sliding rod 512 also slides along the inner wall of the fixing block 513. The two clamping blocks 514 also move towards each other until the clamping blocks 514 are close to the metal part, achieving the function of clamping and fixing. Then, the tapping machine 3 can be started through the control box 2 to tap the metal part. A slider 507 is fixedly connected to the lower surface of the movable block 506. A groove 505 is formed on the surface of the carrier plate 501 corresponding to the position of the slider 507, and the inner wall of the groove 505 is slidably connected to the surface of the slider 507. When the movable block 506 moves, the slider 507 slides along the groove 505, which serves as a guide. A handle 504 is fixedly connected to one end of the lead screw 503. Several grooves are formed on the arc surface of the handle 504. The lead screw 503 can be rotated with the help of the handle 504, achieving a more convenient effect. An anti-slip pad 515 is fixedly connected to one side of the clamping block 514. The anti-slip pad 515 is a rubber pad. The rubber pad has good friction, so the anti-slip pad 515 can make the clamping block 514 more secure when clamping metal parts.

[0035] In the embodiments of this utility model, please refer to Figures 5 to 7The auxiliary device 6 is located on one side of the tapping machine 2, and the position of the auxiliary device 6 corresponds to the position of the tapping head 4. The auxiliary device 6 includes a connecting cylinder 61 and a connecting block 62. The upper surface of the connecting cylinder 61 is fixedly connected to the tapping machine 2, and the lower surface of the connecting block 62 is fixedly connected to the tapping head 4. The arc surface of the connecting block 62 is inserted into the inner wall of the connecting cylinder 61. Guide blocks 64 are fixedly connected to both sides of the connecting block 62. A guide groove 63 is opened on the inner wall of the connecting cylinder 61 corresponding to the position of the guide block 64. The inner wall of the guide groove 63 is slidably connected to the guide block 64. A limit rod 68 is threadedly connected inside the connecting cylinder 61 corresponding to the position of the guide block 64. An insertion hole 65 is opened on the surface of the guide block 64 corresponding to the position of the limit rod 68. The inner wall of the insertion hole 65 is threadedly connected to the limit rod 68. When the tapping head 4 needs to be replaced after prolonged use, first use a tool to rotate the limiting rod 68, moving it away from the insertion hole 65 until it no longer contacts the hole. Then, move the old tapping head 4 downwards and insert the connecting block 62 on the new tapping head 4 into the inner wall of the connecting cylinder 61. Simultaneously, the guide block 64 on the connecting block 62 slides along the guide groove 63 until the connecting block 62 abuts against the connecting cylinder 61. At this point, the insertion hole 65 on the guide block 64 is aligned with the limiting rod 68. Then, rotate the limiting rod 68 in the opposite direction to insert it into the insertion hole 65. The tapping head 4 is now replaced. An auxiliary pad 66, made of silicone, is fixedly connected to the arc surface of the guide block 64. The silicone pad has good sliding properties, preventing the guide block 64 from getting stuck when the connecting block 62 is inserted into the inner wall of the connecting cylinder 61. The arc surface of the limiting rod 68 is threadedly connected to a limiting ring 67, and the arc surfaces of the two limiting rings 67 are fixedly connected to the same connecting cylinder 61. When the limiting rod 68 rotates, the limiting rings 67 can limit the position of the limiting rod 68 to prevent the limiting rod 68 from deviating.

[0036] The working principle of the automatic tapping device for metal parts provided by this utility model is as follows: When the tapping machine 2 is tapping the metal parts, it is necessary to clamp and fix the metal parts first. The metal parts are placed in the loading groove 516. Then, the screw 503 is rotated with the handle 504, so that the screw 503 moves the moving block 506 away from the metal parts. The slider 507 is also moved along the slide groove 505. The connecting seat 508 moves with the moving block 506. The connecting arm 509 rotates. Since the pressing rod 511 can only move along the slide rail 518, the rotation of the connecting arm 509 will cause the pressing rod 511 to move. The pressing rod 511 moves the sliding block 517 along the slide rail 518 towards the metal parts. At the same time, the sliding rod 512 also slides along the inner wall of the fixing block 513. The two clamping blocks 514 also move towards each other until the clamping blocks 514 are close to the metal parts, achieving the function of clamping and fixing. Then, the tapping machine 2 can be started to tap the metal parts through the control box 3.

[0037] When the tapping head 4 needs to be replaced after long-term use, first use a tool to rotate the limiting rod 68, moving the limiting rod 68 away from the insertion hole 65 until the limiting rod 68 no longer contacts the insertion hole 65. Then move the old tapping head 4 downwards and insert the connecting block 62 on the new tapping head 4 into the inner wall of the connecting cylinder 61. At the same time, make the guide block 64 on the connecting block 62 slide along the guide groove 63 until the connecting block 62 abuts against the connecting cylinder 61. At this time, the insertion hole 65 on the guide block 64 is exactly aligned with the limiting rod 68. Then rotate the limiting rod 68 in the opposite direction to insert the limiting rod 68 into the insertion hole 65. In this way, the tapping head 4 is replaced.
