[0031] The following is combined with Figure 1 -Attached Figure 3 This application is described in further detail.
[0032] At present, in order to improve the accuracy of the tapping feed length of a tapping machine, an embodiment of the present application proposes an auxiliary tooling for a tapping machine.
[0033] The present application embodiment discloses a tapping machine auxiliary tooling. Figure 1 A tapping machine auxiliary tooling includes a mounting block 1, a slider 2 slidably connected to the mounting block 1, a reaction mechanism 3 connected to the mounting block 1, and a limit component 4 connected to the mounting block 1. The limit component 4 limits the workpiece to the surface of the mounting block 1. When the workpiece is tapped, the limit component 4 can reduce the possibility of the workpiece swinging at will, thereby improving the stability and safety of the tapping process. The reaction mechanism 3 includes a response component 31 connected to the mounting block 1 and a control component 32 connected to the response component 31. The control component 32 is driven and connected to the tapping machine, so that the control component 32 drives the tapping machine to move, so that the tapping machine drives the tap 5 to rotate and drives the tap 5 to process the workpiece. At the same time, the tapping machine can be controlled not to work, and the slider 2 drives the response component 31, and the response component 31 drives the control component 32 to realize the control of the tapping machine, thereby improving the accuracy of the tapping feed length of the tapping machine.
[0034] Reference Figure 2 and Figure 3 The surface of the mounting block 1 is provided with a sliding hole 11, and the slider 2 is slidably connected to the inside of the sliding hole 11 along the axial direction of the sliding hole 11 to achieve the sliding connection of the slider 2. At the same time, the sliding hole 11 can limit the movement of the slider 2, making the movement of the slider 2 more stable. When processing a workpiece, the user places the position of the workpiece to be tapped above the sliding hole 11. When the tap 5 rotates, it is inserted into the inside of the sliding hole 11 to achieve the tapping process. When the tap 5 continues to move downward, it pushes the slider 2 to move in the direction close to the response component 31. When the slider 2 touches the response component 31, the response component 31 is controlled to work, thereby achieving the control of the response component 31.
[0035] Reference Figure 2 and Figure 3The cross-section of the slider 2 is a T-shaped truncated cone block, and a limiting ring 12 is arranged inside the sliding hole 11. The axis of the slider 2 coincides with the axis of the limiting ring 12. The bottom surface of the slider 2 is slidably connected to the inner diameter surface of the limiting ring 12, and the top of the slider 2 is slidably connected to the inner diameter surface of the sliding hole 11, so that the slider 2 can be limited by the inner diameters of the sliding hole 11 and the limiting ring 12 at the same time, and the movement of the Shudie slider 2 is more stable. At the same time, the limiting ring 12 limits the displacement of the slider 2, reducing the possibility of the slider 2 slipping out of the sliding hole 11.
[0036] Reference Figure 1 The response component 31 includes a first pneumatic valve 311 fixedly connected to the mounting block 1 and a second pneumatic valve 312 connected to the first pneumatic valve 311. The air inlet of the first pneumatic valve 311 is connected to an external air source, and the air outlet of the first pneumatic valve 311 is connected to the air inlet of the second pneumatic valve 312. The reset switch of the first pneumatic valve 311 is located at the bottom end of the sliding hole 11. In the embodiment of the present application, two sliding holes 11 are provided on the mounting block 1, which can realize tapping at two positions of the workpiece. The number of the first pneumatic valves 311 is equal to the number of the sliding holes 11, which can realize the control of two processing stations. The slider 2 moves in the direction close to or away from the reset switch of the first pneumatic valve 311. When the bottom of the slider touches the reset switch of the first pneumatic valve 311, the reset switch of the first pneumatic valve 311 is compressed, and the gas passes through the outlet of the first pneumatic valve 311 and enters the second pneumatic valve 312. The outlet of the second pneumatic valve 312 is connected to the control component 32. When the tapping machine drives the tap 5 to rotate and feed, the tap 5 pushes the slider 2 to move in the direction close to the reset switch of the first pneumatic valve 311. By driving the first pneumatic valve 311, the second pneumatic valve 312 is controlled.
[0037] Reference Figure 1 The control component 32 includes a pneumatic solenoid valve 321 connected to the second pneumatic valve 312, a cylinder 322 connected to the pneumatic solenoid valve 321, and a third pneumatic valve 323 connected to the pneumatic solenoid valve 321. A contact plate 3221 is provided at the output end of the cylinder 322.

When the contact plate 3221 touches the reset switch of the second pneumatic valve 312, the second pneumatic valve 312 can be controlled to open. When the contact plate 3221 touches the reset switch of the third pneumatic valve 323, the third pneumatic valve 323 can be controlled to open.
[0038] Furthermore, the pneumatic solenoid valve 321 and the third pneumatic valve 323 are both connected to an external air source, a piston is respectively arranged on both sides of the pneumatic solenoid valve 321, the pneumatic solenoid valve 321 is provided with an A airway hole 3211 and a B airway hole 3212, the air outlet of the second pneumatic valve 312 is connected to one of the pistons of the pneumatic solenoid valve 321, the air outlet of the third pneumatic valve 323 is connected to the other piston of the pneumatic solenoid valve 321, the A airway hole 3211 and the B airway hole 3212 are respectively connected to the two air holes of the cylinder 322, and the B airway hole 3212 is connected to the tapping machine. After the second pneumatic valve 312 is driven by the first pneumatic valve 311, the gas continuously sprays from the second pneumatic valve 312 on the piston of the pneumatic solenoid valve 321, so that the external gas source and the A airway hole 3211 are connected, and the gas is blown out from the A airway hole 3211 until it reaches the air hole of the cylinder 322, so that the abutment plate 3221 moves toward the direction close to the third pneumatic valve 323. At this time, the abutment plate 3221 is away from the reset switch of the second pneumatic valve 312, the second pneumatic valve 312 is closed, the A airway hole 3211 is closed, the tapping machine is cut off from air, and the tapping machine does not work, reminding the user that the feed length is sufficient and the tap 5 does not need to be forwardly rotated for tapping. At the same time, the second pneumatic valve 312 drives the output end of the cylinder 322 to move toward the reset switch of the third pneumatic valve 323 through the pneumatic solenoid valve 321, and the second pneumatic valve 312 is driven by the pneumatic solenoid valve 321 The purpose of driving the tapping machine to cut off the air; when the abutment plate 3221 abuts against the reset switch of the third pneumatic valve 323, the third pneumatic valve 323 is opened, and the gas flowing out of the outlet of the third pneumatic valve 323 is sprayed on the piston of the pneumatic solenoid valve 321, so that the B airway hole 3212 is connected, and the gas enters another air hole of the cylinder 322, so that the abutment plate 3221 can move toward the second pneumatic valve 312, and the B airway hole 3212 is connected to the tapping machine, and the tapping machine is turned on. At this time, the user controls the tapping machine to reverse, and the tap 5 reversely exits the sliding hole 11, the reset switch of the first pneumatic valve 311 is reset, and the slider 2 is pushed to reset, thereby achieving the purpose of the third pneumatic valve 323 driving the output end of the cylinder 322 to move in the opposite direction through the pneumatic solenoid valve 321, and at the same time achieving the purpose of the third pneumatic valve 323 driving the tapping machine to supply air through the pneumatic solenoid valve 321.
[0039] Reference Figure 2 and Figure 3 The limit assembly 4 includes a limit frame 41 fixedly connected to the mounting block 1 and a limit block 42 rotatably connected to the mounting block 1. The limit block 42 abuts against an opening on one side of the limit frame 41.
