[0025] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.

[0026] Reference Figure 1 A multi-functional parts processing machine tool includes a machine tool body 1, a horizontally set worktable mounted on the machine tool body 1, a mounting fixture for positioning parts on the worktable, a drilling and milling power mechanism for processing the head of the parts, a shearing die mechanism for deburring the jaws of the parts, a torque detection mechanism for detecting the connection strength between the extension 29 and the tubular part 27, a bending resistance detection mechanism for detecting the connection strength between the connector 28 and the tubular part 27, and a cutting mechanism for processing the crescent groove inside the tail tube.

[0027] Reference Figure 1 and Figure 2 The installation fixture includes a support base 2 fixed on the worktable. A set of V-shaped frames 3 supporting two tubular parts 27 are provided on the support base 2. The two V-shaped frames 3 are supported near the middle of the tubular parts 27. A pair of vertically arranged positioning plates 4 are fixed on the worktable. A rotary motor 5 is fixed on the positioning plates 4. A positioning pressure plate 6 is fixed on the output shaft of the rotary motor 5 through a rotating shaft. The side walls of the two positioning pressure plates 6 abut against the end face of the tubular parts 27, and the lower end abuts against the connecting piece 28. The positioning pressure plate 6 is provided with a clearance groove to facilitate the subsequent processing of the crescent groove on the inner wall of the tubular parts 27 and to prevent the positioning pressure plate 6 from interfering with the processing. The rotary motor 5 drives the positioning pressure plate 6 to rotate outward, and the positioning pressure plate 6 separates from the corresponding tubular part 27, thereby facilitating the installation and disassembly of the workpiece.

[0028] Reference Figure 2 and Figure 3A vertically arranged rotary tension cylinder 7 is fixed on the support seat 2 between the two V-shaped frames 3. A horizontally arranged floating pressure plate 8 is fixed on the connecting rod of the rotary tension cylinder 7. The rotary tension cylinder 7 can be a 90-degree rotary tension cylinder 7. The rotary tension cylinder 7 drives the floating pressure plate 8 to rotate to the direction parallel to the tubular part 27, which facilitates the installation and disassembly of the workpiece. After the workpiece is installed, the rotary tension cylinder 7 drives the floating pressure plate 8 to rotate to the direction perpendicular to the tubular part 27, and drives the floating pressure plate 8 to move downward, so that the floating pressure plate 8 presses the tubular part 27 tightly.

[0029] Reference Figure 2 and Figure 3 The shearing die mechanism includes two stroke slides 9 fixed on the worktable. The two stroke slides 9 are located outside the two tubular parts 27 and face the jaws 30. A punch seat 10 is slidably mounted on the stroke slides 9. An execution cylinder 11 is mounted on the worktable, which connects to the punch seat 10 and drives the punch seat 10 to move. A punch 12 is mounted on the punch seat 10. A positioning seat 31 is mounted on the worktable and is located between the two tubular parts 27. Dies 13 that cooperate with the punch 12 are mounted on both sides of the positioning seat 31. A punching hole 14 is provided in the cutting edge of the die 13. The punching hole 14 is a flat cylindrical hole with an oblong cross section. The punch 12 cooperates with the punching hole 14 to remove the overflow material at the jaws 30. The end of the punch 12 is fixed with a guide boss 15 that is embedded in the punch hole 14. The guide boss 15 guides the punch 12. When the stroke slide 9 retracts and demolds, the guide does not disengage, ensuring that the cutting edge does not interfere.

[0030] Reference Figure 3 and Figure 4 Rotary bearings are provided on the die 13 and the punch 12. The rotary bearings are rotatably connected to the corresponding positioning seat 31 and punch seat 10, which allows the angles of the punch 12 and die 13 to be rotated when the jaws 30 of different workpieces have different angles, thus eliminating the trouble of changing the shearing die. In addition, the rotation function here also serves to synchronize the rotation when the torque detection mechanism is shared.

[0031] Reference Figure 4 and Figure 5 The torque detection mechanism includes a punch 12 as a rotating probe, a die 13 as a central support frame, and a punch seat 10 as a rotating transmission shaft. The punch seat 10 is provided with a transmission sprocket 16 that drives the punch 12 to rotate. A servo motor is fixed on the worktable. A reducer is connected to the output shaft of the servo motor. A drive sprocket 17 is coaxially fixed on the output shaft of the reducer. A transmission chain connected to the transmission sprocket 16 is provided on the drive sprocket 17.

[0032] When the torque mechanism is working, the servo motor outputs a preset fixed torque, which, through the combined action of the reducer, drive sprocket 17, drive chain, and transmission chain, drives the rotating shaft to rotate. The rotating probe then twists the workpiece jaws 30. If the workpiece strength meets the standard, the probe rotates within a limited range; if the workpiece strength does not meet the standard, the rotating probe will damage the workpiece jaws 30, continuing to rotate beyond the preset limited range. The driver controlling the servo motor will then output an alarm, and the CNC system will determine that the workpiece is unqualified.

[0033] Reference Figure 3 and Figure 4 The bending resistance testing mechanism includes a mounting frame 18 fixed on the workbench. The mounting frame 18 has a gantry structure. The connecting piece 28 is located below the mounting frame 18. A vertically arranged output cylinder 19 is fixed on the mounting frame 18. A bending resistance rod that penetrates the mounting frame 18 is fixed on the output shaft of the output cylinder 19 and acts on the bending resistance rod of the connecting piece 28.

[0034] When the bending resistance testing mechanism is working, since the V-shaped frame 3 is located in the middle of the workpiece and a certain distance from the pipe opening, the punch 12 and die 13 in the shearing die mechanism play a certain role in fixing the workpiece. By setting a preset pressure value, the output cylinder 19 is activated, and the bending resistance ejector rod acts on the double-pipe connection part of the workpiece. If the workpiece strength is qualified, the ejector rod's ejection distance is within the effective range; if the workpiece strength is unqualified, the ejector rod's ejection distance will exceed the effective range, and the position sensor on the side of the output cylinder 19 will send a signal to the CNC system to determine whether the workpiece is qualified.

[0035] Reference Figure 4 and Figure 5 The drilling and milling power mechanism includes two two-stage forming milling cutters for milling the bottom hole and burrs at the hole opening of the tube. The two-stage forming milling cutters correspond to the tubular component 27. A sliding seat 21 is provided on the worktable. The length direction of the sliding seat 21 is perpendicular to the axial direction of the tubular component 27 and slides along the axial direction of the tubular component 27. The sliding seat 21 is provided with two sliding brackets 22 that slide along the length direction of the sliding seat 21. The movement direction of the two sliding brackets 22 is perpendicular to the axis of the tubular component 27. A sliding block 23 that moves in the vertical direction is slidably provided on the sliding bracket 22. A lead screw is rotatably connected to both the sliding seat 21 and the sliding bracket 22. The lead screw is threadedly connected to the corresponding sliding bracket 22 and the sliding block 23, and the movement direction of the corresponding sliding bracket 22 and the sliding block 23 is controlled by the lead screw. A handle is fixed to the end of the lead screw. By rotating the handle, the corresponding sliding bracket 22 or the sliding block 23 is driven to move. The two-stage forming milling cutter is rotatably connected to the corresponding sliding block 23. The drilling and milling power mechanism also includes a drilling and milling servo motor and a drilling and milling reducer that drive the two-stage forming milling cutter to rotate. The worktable is rotatably connected to a ball screw that drives the sliding seat 21 to move toward the tubular part 27 and a drilling and milling servo motor that drives the ball screw to rotate.

[0036] The X-axis is the direction parallel to the axis of the tubular component 27, the Z-axis is the height direction, and the Y-axis is the horizontal direction perpendicular to the axis of the tubular component 27.

[0037] The operation involves rapid traverse along the X-axis to approach the workpiece machining position, cutting along the X-axis to the final position, and then rapid retraction along the X-axis to a safe position. All movements are on the X-axis, with no machining motion in the Y and Z axes. However, different workpiece models and specifications may have variations in the height of the hole center during clamping. Therefore, in designing the drilling and milling power mechanism, the X-axis movement is set as a sleeve-type telescopic automatic feed axis, controlled by a drilling and milling servo motor; the Y / Z axes are manually adjustable axes to meet the requirements of different product models.

[0038] Reference Figure 1 and Figure 6 The cutting mechanism includes two guide slides 20 fixed on the worktable and corresponding to the tubular component 27. The length direction of the guide slides 20 is parallel to the axial direction of the tubular component 27. A cutting slide 24 is slidably mounted on the guide slides 20. A vertically mounted lifting slide 25 is installed on the cutting slide 24. The lifting slide 25 and the cutting slide 24 have waist-shaped grooves along the direction perpendicular to the axis of the tubular component. Bolts are inserted into the waist-shaped grooves and nuts are tightened to position the lifting slide 25 on the cutting slide 24, facilitating adjustment. The relative distance between the two lifting slides 25 is specified. A cutting slide 26 that moves vertically is slidably connected to the lifting slide 25. Both the guide slide 20 and the lifting slide 25 are rotatably connected to ball screws. The ball screws are threadedly connected to the corresponding cutting slide 24 and cutting slide 26. The cutting mechanism also includes an adjusting servo motor that drives the corresponding ball screw to rotate. The cutting mechanism also includes a three-sided milling cutter that is rotatably mounted on the cutting slide 26 and a chip servo motor and a cutting reducer that control the rotation of the three-sided milling cutter.

[0039] The machining process involves rapid feed along the X-axis into the tube opening, accurately positioning it at the crescent groove position, cutting along the Z-axis to the desired depth, then rapid retraction along the Z-axis back to the feed start point, and finally rapid retraction along the X-axis to the safe position. All machining movements occur along the X and Z axes, with no machining movement along the Y-axis. For workpieces of different models and specifications, the center distance between the tube openings may change during clamping. Therefore, in designing the cutting mechanism, the X and Z-axis movements are set as automatic feed axes controlled by servo motors; the Y-axis is a manual quick-adjustment axis, with the center distance quickly adjusted by changing the quick-change positioning block.

[0040] Reference Figure 1 The machine tool body 1 is provided with an inverted conical opening, and a cooling chip collection system is provided at the bottom of the inverted conical opening. The cooling chip collection system includes a drawer-type chip collection box located on the upper layer and a water tank located on the lower layer. The bottom of the chip collection box is provided with a mesh densely distributed to isolate solid waste chips and allow the filtered coolant to flow to the water tank.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
