[0002] In the field of mechanical manufacturing, thread is one of the most basic and widely used structural elements for connection, fastening, transmission and sealing. Almost all mechanical equipment, instruments and meters, automobiles, aerospace vehicles, electronic products and even daily necessities contain a large number of internal threaded holes, such as bolt and nut connections, equipment housing assembly, hydraulic and pneumatic joints, transmission screw matching, etc. Tapping is the core process of internal thread processing.

[0011] The present invention provides a tapping device for machining mechanical parts. It has the following beneficial effects: 1. When using the tapping device for machining mechanical parts, the user puts the mechanical parts to be machined into the storage bin and stores them for use in the next work. After the first pneumatic piston rod is started, it is extended and retracted. The telescopic movement of the first pneumatic piston rod drives the first push rod to move. The movement of the first push rod drives the mechanical parts to be machined in the storage bin to move. When the mechanical parts move to the position of the second pneumatic piston rod, the second pneumatic piston rod telescopic movement. The telescopic movement of the second pneumatic piston rod drives the second push rod to move. The movement of the second push rod drives the mechanical parts that have moved to the second pneumatic piston rod to move. Finally, the mechanical parts are moved to the carrying plate, and then the tapping device can perform tapping. The entire process only requires putting the mechanical parts into the storage bin for storage in advance. The rest of the process does not require manual participation, thereby completing the automatic loading operation, reducing manual intervention, and improving work efficiency.
[0012] The first gear rod is engaged with the gear column, so the first gear rod moves and drives the gear column to rotate. Since the gear column and the second gear rod are engaged, the gear column rotates and drives the second gear rod to move. The second gear rod moves and drives the second sliding base plate to slide on the second slide rail. The second gear rod moves and drives the second fixed rod to move. Under the back and forth telescopic movement of the third pneumatic piston rod, the first fixed rod and the second fixed rod can be driven to move back and forth, so that the mechanical parts on the carrying plate can be clamped and fixed, thereby avoiding the breakage of the tap due to unstable fixation caused by traditional manual fixation of mechanical parts, and avoiding the poor consistency caused by manual fixation, thereby reducing labor intensity.
[0013] 3. When the tapping device for machining mechanical parts is used, after the fixing device fixes the mechanical part on the supporting plate, when the tapping device is tapping, the tap rotates spirally on the mechanical part, and drills threads downward while rotating, thereby pressing the mechanical part. When the tapping speed is high, the rotation speed increases, the pressure on the mechanical part increases, and the pressure on the supporting plate increases, resulting in a certain rigid deformation that causes the supporting plate to move downward. The downward movement of the supporting plate drives the pressure detection plate to move downward, and the downward movement of the pressure detection plate drives the spring telescopic rod to move downward. The spring telescopic rod moves and contracts, thereby squeezing the pressure signal receiving module. The pressure signal receiving module can thereby receive the pressure signal and send a signal when a certain threshold is reached, thereby adjusting the tapping speed, avoiding the tap breakage caused by excessive tapping speed, reducing costs, and reducing safety hazards.
[0014] 4. When the tapping device for machining mechanical parts is used, since many mechanical parts need to be tapped at different positions, when tapping at different positions on the mechanical parts, a first sliding groove is provided on the bracket, and the first electric slider is started, so that it can slide up and down on the first sliding groove on the bracket, thereby realizing Z-axis movement in three-dimensional space. Since a second sliding groove is provided on the sliding beam, the second electric slider is started, so that it can slide on the second sliding groove on the sliding beam, and the movement of the second electric slider drives the sliding column to move, thereby realizing movement on the X-axis in three-dimensional space. Since a fourth pneumatic piston rod is fixedly connected to the sliding column, the fourth pneumatic piston rod is telescopically moved to drive multiple types of tapping devices to move, thereby realizing movement on the Y-axis in three-dimensional space. In summary, it can move on the X, Y, and Z axes in three-dimensional space, thereby realizing tapping operations at different positions on the mechanical parts, realizing automated operation, and reducing costs.
[0015] 5. When the tapping device for machining mechanical parts is used, when the mechanical parts have different tapping thread requirements, the servo motor is started, and the driving shaft of the servo motor rotates to drive the rotating plate to rotate. The rotation of the rotating plate drives the A-type tap, B-type tap, and C-type tap on the rotating plate to rotate around the center of the rotating plate. The tap that rotates to the top of the workpiece starts tapping it, thereby starting the corresponding stepper motor, and the driving shaft of the corresponding stepper motor rotates to drive the corresponding tap to rotate, so that it can cope with mechanical parts with different thread requirements, thereby reducing the time caused by frequent replacement of taps of different models and improving work efficiency.

[0021] When in use, after the second pneumatic piston rod 35 pushes the mechanical parts to the carrier plate 37, the operation of fixing the mechanical parts is performed, and the third pneumatic piston rod 48 is started to telescopically move, thereby driving the first gear rod 42 to move, and the movement of the first gear rod 42 drives the first sliding base plate 44 to slide on the first slide rail 46, and the movement of the first gear rod 42 drives the first fixing rod 49 to move. Since the first gear rod 42 is engaged with the gear column 41, the movement of the first gear rod 42 drives the gear column 41 to rotate. Since the gear column 41 is engaged with the second gear rod 43, the gear column 41 rotates. The second gear rod 43 is driven to move, and the movement of the second gear rod 43 drives the second sliding base plate 45 to slide on the second slide rail 47.

[0022] See also Figure 1-Figure 5 The present invention provides a technical solution: the pressure detection device 8 includes a pressure signal receiving module 81, the top of the pressure signal receiving module 81 is fixedly connected to a spring telescopic rod 82, the top of the spring telescopic rod 82 is fixedly connected to a pressure detection plate 83, the pressure signal receiving module 81 is fixedly connected to the top of the placement slot 7, and the pressure detection plate 83 is fixedly connected to the bottom of the supporting plate 37.
[0023] During use, after the fixing device 4 fixes the mechanical parts on the supporting plate 37, when the tapping device is tapping, the tap rotates spirally on the mechanical parts, drilling threads downward while rotating, thereby pressing the mechanical parts. When the tapping speed is high, the rotation speed becomes larger, the pressure on the mechanical parts becomes larger, and the pressure on the supporting plate 37 becomes larger.

The bracket 51 is fixedly connected to the top of the working platform 2, and the fourth pneumatic piston rod 58 is fixedly connected to the side of the multi-type tapping device 6.
[0025] During use, since many mechanical parts need to be tapped at different positions, when tapping different positions on the mechanical parts, since the first sliding groove 52 is provided on the bracket, the first electric slider 53 is started, so that it can slide up and down on the first sliding groove 52 on the bracket, realizing Z-axis movement in three-dimensional space. Since the second sliding groove 55 is provided on the sliding beam 54, the second electric slider 56 is started, so that it can slide on the second sliding groove 55 on the sliding beam 54.
