At the same time, the third sliding translator 29 is started, and the third sliding translator 29 drives the third linkage table 210 to move, and the third linkage table 210 drives the processing fixture 211 to move, so that the processing fixture 211 drives the workpiece to be processed to move in the longitudinal direction, so as to adjust the processing position of the drill bit 27 in the longitudinal direction.

[0049] Example 3

[0050] like Figure 5 - Figure 8As shown, the difference from the above embodiment is that the auxiliary mechanism 3 also includes a slide rail frame 31, the slide rail frames 31 are fixedly installed on both sides of the body 1, and the slide rail frames 31 are slidably matched with moving parts 32, and the moving trajectory of the moving parts 32 is in the vertical up and down direction.

The rail frame 35 is divided into two parts and arranged on both sides of the processing fixture 211. The rail frames 35 on both sides are symmetrically distributed. The rail frames 35 are rotatably matched with conveying rollers 36. The conveying rollers 36 on both sides are adjacent, and the conveying rollers 36 on both sides are respectively tensioned with conveyor belts 37. Stepper motors 38 are fixedly installed on the rail frames 35 on both sides. The stepper motors 38 on both sides are respectively connected to the single conveying rollers 36 on both sides, and the conveying rollers 36 on both sides use toothed belts for overall power transmission.

[0052] Furthermore, a main replacement frame 39 is fixedly installed on one side of the body 1. The main replacement frame 39 and the drill bit 27 are located at the same height. The main replacement frame 39 is a "U"-shaped structure. One end of the main replacement frame 39 adjacent to the drill bit 27 is an open end.

The placement port 312 is adapted to the drill bit 27.

[0053] Furthermore, a guide plate 313 is rotatably provided at the connection between the main replacement frame 39 and the auxiliary replacement frame 311, one end of the guide plate 313 extends into the main replacement frame 39, and the other end of the guide plate 313 extends into the auxiliary replacement frame 311. When the drill bit 27 pushes the guide plate 313 to rotate, one end of the guide plate 313 and the other end of the guide plate 313 both rotate toward the direction of the connection between the adjacent main replacement frame 39 and the auxiliary replacement frame 311, and a torsion spring 314 is sleeved on the shaft of the guide plate 313, one end of the torsion spring 314 is connected to the guide plate 313, and the other end of the torsion spring 314 is connected to the main replacement frame 39.

The drill bit 27 pushes against the guide plate 313. Because the guide plate 313 can only rotate counterclockwise when subjected to force, the guide plate 313 releases the clamping state between the drill bit 27 and the drilling motor 26, and uses the guide plate 313 to guide the removed drill bit 27 into the auxiliary replacement frame 311, so that the removed drill bit 27 will stop on the placement port 312. As the drilling motor 26 continues to move, the mounting seat on the drilling motor 26 is clamped and fixed with the drill bit 27 of another specification at the replacement port 310, and then the overall structure is reset, so that the specifications of the drill bit 27 can be smoothly replaced in a single processing flow.

[0055] The overall working principle:

[0056] First, the workpiece to be processed is placed on the conveyor belt 37, and the drilling processing equipment is started. The conveyor belt 37 conveys the workpiece to be processed to the processing fixture 211, and the workpiece to be processed is limited and fixed on the processing fixture 211, and then the drill bit 27 is started, and the drill bit 27 performs drilling processing on the workpiece to be processed. When the specification of the drill bit 27 needs to be changed, that is, when the drill bit 27 is replaced, the drill bit 27 is moved into the main replacement rack 39, so that the drill bit 27 is unloaded from the main replacement rack 39 through a snap-fit ​​connection mode, and the other drill bit 27 is snapped back, so that the drill bit 27 completes the specification conversion, so as to perform drilling processing of different specifications on the same workpiece to be processed, so that one device can perform drilling processing on drill bits of multiple specifications in one processing flow, thereby reducing the use cost of the equipment and improving the processing efficiency of a single part;

[0057] When drilling, after the workpiece is placed on the processing jig 211, the positioner 212 is started, and the positioner 212 limits and fixes the workpiece on the processing jig 211, and then the first sliding translator 22 on the fixed column 21 is started, the first sliding translator 22 drives the first linkage table 23 to move, the first linkage table 23 drives the second sliding translator 24 to move, the second sliding translator 24 is started, the second sliding translator 24 drives the second linkage table 25 to move, and the second linkage table 25 drives the drilling motor 26 to move. The drilling motor 26 is started, the drilling motor 26 drives the drill bit 27 to rotate, so that the drill bit 27 is pressed against the workpiece to be processed while rotating, thereby adjusting the position of the drill bit 27 in the horizontal direction and performing drilling processing on the workpiece to be processed. At the same time, the third sliding translator 29 is started, the third sliding translator 29 drives the third linkage table 210 to move, and the third linkage table 210 drives the processing fixture 211 to move, so that the processing fixture 211 drives the workpiece to be processed to move in the longitudinal direction, thereby adjusting the processing position of the drill bit 27 in the longitudinal direction;

[0058] When the workpiece to be processed is transmitted, the workpiece to be processed is placed on the conveyor belt 37, and the stepper motor 38 is started. The stepper motor 38 drives the conveyor roller 36 to rotate, and the conveyor roller 36 drives the conveyor belt 37 to rotate, so that the conveyor belt 37 drives the workpiece to be processed to move on the rail frame 35, so as to move the workpiece to be processed to a relative position with the processing fixture 211 and stop moving, and then the servo motor 34 is started, and the servo motor 34 drives the screw rod 33 to rotate, and the screw rod 33 drives the moving part 32 to move on the slide rail frame 31, and the moving part 32 drives the rail frame 35 to move, so that the rail frame 35 is lifted or lowered, so as to place the workpiece to be processed on the rail frame 35 on the processing fixture 211, so as to form an automatic transmission of the workpiece to be processed, and when the specifications of the drill bit 27 need to be changed , driving the drill bit 27 to move into the main replacement rack 39, and a drill bit 27 of another specification is placed on the replacement port 310 in advance, and the drill bit 27 pushes against the guide plate 313. Because the guide plate 313 can only rotate counterclockwise when subjected to force, the guide plate 313 releases the clamping state between the drill bit 27 and the drilling motor 26, and uses the guide plate 313 to guide the removed drill bit 27 into the auxiliary replacement rack 311, so that the removed drill bit 27 will be stopped on the placement port 312. As the drilling motor 26 continues to move, the mounting seat on the drilling motor 26 is clamped and fixed with the drill bit 27 of another specification at the replacement port 310, and then the overall structure is reset, so that the specifications of the drill bit 27 can be smoothly replaced in a single processing flow.

[0059] A drilling method for processing a relief valve, using the above-mentioned drilling processing equipment, comprises the following steps:

[0060] S1: placing the workpiece to be processed on the conveyor belt 37, and the conveyor belt 37 drives the workpiece to be processed to the processing fixture 211;

[0061] S2: The workpiece to be processed is fixed on the processing fixture 211, and the drill bit 27 performs drilling processing on the workpiece to be processed;

[0062] S3: When the drill bit 27 needs to be replaced, the drill bit 27 is moved into the main replacement frame 39, and the drill bit 27 is replaced on the main replacement frame 39 by a snap-fit ​​connection;
