Description

Technical Field

[0001] This utility model relates to the field of tapping machine technology, and in particular to a tapping clamp for a tapping machine. Background Technology

[0002] A tapping machine is a mechanical processing device that processes internal threads, screws, or threads on the inner surfaces of various through-hole or blind-hole parts such as machine housings, equipment end faces, nuts, and flanges. Tapping machines are also called thread tapping machines, thread tapping machines, and automatic tapping machines. The use of a tapping machine requires the use of a fixture.

[0003] The clamps currently used in the market for holding and fixing nuts rely on manual feeding and unloading, resulting in low automation levels. This is not conducive to the establishment of current automated production lines and affects processing efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by this patent application is how to provide a tapping jig for a tapping machine that can achieve automatic feeding and unloading, has a high degree of automation, and is easy to use.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A tapping fixture for a tapping machine includes a fixture base plate fixedly mounted on a machine base. Two supports are fixedly mounted on the fixture base plate, and rotating shafts are rotatably mounted on the supports. The inner ends of the two rotating shafts are fixedly connected to a tilting frame. A tilting motor is fixedly mounted on one of the supports, and the output shaft of the tilting motor is fixedly connected to one end of the rotating shaft. A moving cylinder is fixedly mounted inside the tilting frame. A mounting seat is fixedly mounted on the cylinder rod of the moving cylinder. The mounting seat has a mounting groove, and a clamping structure for moving two clamping plates closer together or further apart is installed in the mounting groove. The clamping plates are fixedly equipped with clamping blocks on both sides of the mounting base. The clamping blocks have clamping openings that conform to the shape of the nuts. The two sides of the clamp base plate are respectively equipped with a feeding track and a support base. The support base and the clamp base plate are provided with clearance holes. The feeding track has a track groove that allows a single row of nuts to pass through. The track groove is U-shaped. A limit plate is fixed to the end of the feeding track near the support base. The two sides of the end of the feeding track near the support base are provided with clearance parts. The size of the clearance parts along the length of the feeding track is larger than the diameter of the circle containing a single nut.

[0007] In this design, a vibratory feeder is connected to the feeding track. Nuts are fed into the track groove via the vibratory feeder and arranged in a single row within the track groove. When a nut moves to the position of the limiting plate, the limiting plate limits the nut. A clearance portion at the end allows the clamping block to hold the nut located at the end. During nut clamping, the clamping structure moves the two clamping plates closer together, using the clamping openings to hold the nut. The nut is a hexagonal nut, and the three surfaces of the clamping openings are in contact with the nut. Then, a flipping motor drives the flipping frame to rotate, causing the flipping frame to flip the nut to the support seat. A tapping structure then taps the nut. After tapping, a moving cylinder extends, moving the flipping frame and subsequently the nut outwards. The clamping structure releases, and the nut falls freely, completing the unloading process. This fixture enables automatic nut feeding and unloading, improving the level of automation, facilitating assembly into automated production lines, and providing ease of use.

[0008] The flipping frame has guide grooves on both sides, and guide blocks that slide in cooperation with the guide grooves are fixedly installed on both sides of the mounting base.

[0009] The clamping structure includes a clamping cylinder fixedly installed in the mounting groove. The cylinder rod of the clamping cylinder passes through the mounting base and is fixedly connected to one of the clamping plates. Two sets of power transmission components are installed between the two clamping plates.

[0010] The power transmission assembly includes two slide rails fixedly installed in the mounting groove. A rack is slidably fitted on the slide rails. A gear is rotatably installed in the mounting groove. Both sides of the gear mesh with the rack. A guide rod is fixed to one end of each rack that is far apart from the other. The guide rod passes through the mounting base and is fixedly connected to the clamp.

[0011] The feeding track has baffles protruding from both sides of the track groove.

[0012] A rubber pad is fixedly installed on the side wall of the clamping port.

[0013] In summary, the tapping fixture for this tapping machine has the advantages of automatic feeding and unloading, high degree of automation, and ease of use. Attached Figure Description

[0019] like Figure 1-4 As shown, a tapping fixture for a tapping machine includes a fixture base plate 2 fixedly mounted on a machine base 1. Two supports are fixedly mounted on the fixture base plate, and rotating shafts are rotatably mounted on the supports. The inner ends of the two rotating shafts are fixedly connected to a tilting frame 3. A tilting motor 4 is fixedly mounted on one of the supports, and the output shaft of the tilting motor is fixedly connected to one end of the rotating shaft. A moving cylinder 5 is fixedly mounted inside the tilting frame. A mounting seat 6 is fixedly mounted on the cylinder rod of the moving cylinder. The mounting seat has a mounting groove, and a clamping structure for moving two clamping plates 7 closer together or further apart is installed in the mounting groove. The clamping plates are fixedly equipped with clamping blocks 8 on both sides of the mounting base. The clamping blocks have clamping openings that conform to the shape of nuts 9. The two sides of the clamp base plate are respectively equipped with a feeding track 10 and a support base 11. The support base and the clamp base plate are provided with clearance holes 12. The feeding track has a track groove that allows a single row of nuts to pass through. The track groove is U-shaped. The end of the feeding track near the support base is fixed with a limit plate 13. The two sides of the end of the feeding track near the support base are provided with clearance parts. The size of the clearance parts along the length of the feeding track is larger than the diameter of the circle where a single nut is located.

[0020] In this design, a vibratory feeder is connected to the feeding track. Nuts are fed into the track groove via the vibratory feeder and arranged in a single row within the track groove. When a nut moves to the position of the limiting plate, the limiting plate limits the nut. A clearance portion at the end allows the clamping block to hold the nut located at the end. During nut clamping, the clamping structure moves the two clamping plates closer together, using the clamping openings to hold the nut. The nut is a hexagonal nut, and the three surfaces of the clamping openings are in contact with the nut. Then, a flipping motor drives the flipping frame to rotate, causing the flipping frame to flip the nut to the support seat. A tapping structure then performs a tapping operation on the nut. After tapping, a moving cylinder extends, moving the flipping frame and subsequently the nut outwards. The clamping structure releases, and the nut falls freely, completing the unloading process. This fixture enables automatic nut feeding and unloading, improving the level of automation, facilitating assembly into automated production lines, and providing ease of use. The clearance holes facilitate unloading during tapping.

[0021] In practice, guide grooves 14 are provided on both sides of the tilting frame, and guide blocks 15 that slide in cooperation with the guide grooves are fixedly installed on both sides of the mounting base. This facilitates guiding and supporting the movement of the tilting frame.

[0022] In implementation, the clamping structure includes a clamping cylinder 16 fixedly installed in the mounting groove. The cylinder rod of the clamping cylinder passes through the mounting base and is fixedly connected to one of the clamping plates. Two sets of power transmission components are installed between the two clamping plates. The clamping cylinder drives one of the clamping plates to move, and the power transmission components drive the other clamping plate to move, thereby realizing power transmission and enabling better clamping and loosening of the nut.

[0023] In implementation, the power transmission assembly includes two slide rails 17 fixedly installed in the mounting groove. A rack 18 is slidably fitted onto each slide rail. A gear 19 is rotatably installed in the mounting groove, with both sides of the gear meshing with the rack. Guide rods 20 are fixed to the ends of the two racks that are far apart from each other. The guide rods pass through the mounting base and are fixedly connected to the clamping plates. A clamping cylinder drives the clamping plates to move, which in turn moves the guide rods connected to the clamping plates. Under the transmission action of the gears and racks, the other clamping plate moves, thus realizing power transmission. Two guide rods are provided, each fixedly connected to one of the two clamping plates.

[0024] In practice, baffles 21 are provided on both sides of the feeding track, directly opposite the track groove. This helps to limit the nuts entering the track groove, preventing them from jumping vertically due to accumulation, thus making the feeding of nuts more stable.

[0025] During implementation, a rubber pad is fixedly installed on the side wall of the clamping opening. This increases friction, stabilizes the clamping of the nut, and also prevents damage to the nut surface, thus better ensuring the surface quality of the nut.

[0026] Specifically, it also includes a PLC controller, which is connected to the tilting motor, moving cylinder and clamping cylinder for controlling the operation. The model can be Siemens S7-200PLC, which is existing technology.

[0027] Finally, it should be noted that those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims and their equivalents, this utility model also intends to include these modifications and variations.
