The first screw rod 123 is vertically arranged on the carrying plate 110 and is rotationally connected with the carrying plate 110. The pressing plate 122 is arranged on the first screw rod 123 in a manner capable of ascending and descending, so that when the workpiece 140 is installed on the fixing seat 121, the pressing plate 122 is driven to ascend and descend by rotating the first screw rod 123, thereby pressing against the workpiece 140 and fixing the workpiece 140 on the carrying plate 110. Then, the carrying plate 110 is rotated at an angle by cooperating with a tool, so that the workpiece 140 is rotated at an angle relative to the tool, thereby machining the first machining area.

[0045] In some embodiments of the present application, the first clamping assembly 120 comprises a first clamping assembly 120 and a second clamping assembly 130. Figure 2 The first clamping assembly 120 comprises a first clamping assembly 120 and a second clamping assembly 130. Figure 3 The guide comprises a top plate 1241 and a telescopic rod 1242.

After the plug-in block 150 is inserted, the air in the avoiding groove 250 is discharged through the exhaust channel by controlling the switch of the exhaust pipeline 2100, so as to reduce the air pressure in the avoiding groove 250, so that the spring 291 drives the abutting block 280 to abut against the ball 260 again by the elastic force, so that the ball 260 abuts against the groove bottom of the abutting groove 151, so as to fix the relative position of the plug-in block 150 in the plug-in groove 240, so as to fix the relative position of the bearing plate 110 in the mounting seat 210, so as to complete the rapid installation of the bearing plate 110.

[0058] It can be understood that, in some embodiments of the present application, reference is made to Figure 7 The placing rack 300 comprises a base 310 and a bearing seat 320. The bearing seat 320 is borne on the base 310. The bearing seat 320 comprises a bottom plate 321 and two parallel support plates 322 vertically arranged on the bottom plate 321. The top of the support plate 322 is provided with a through groove 323. The through groove 323 is arranged along the length direction of the bottom plate 321 and penetrates through the two side walls of the support plate 322, so that the two ends of the bearing plate 110 can be borne in the two through grooves 323 respectively, thereby enabling the bearing plate 110 to be arranged between the two support plates 322. In some embodiments, the number of the bearing seats 320 is multiple. The multiple bearing seats 320 are arranged at intervals on the base 310, so that the placing rack 300 can bear multiple jigs.

[0059] The embodiment of the third aspect of the present application proposes a processing method applied to the processing system in the embodiment of the second aspect, which comprises the following steps:

[0060] Clamp the workpiece 140 to the first clamping assembly 120 to process the workpiece 140 in the first process; clamp the workpiece 140 to the second clamping assembly 130 to process the workpiece 140 in the second process;

[0061] When the workpiece 140 is processed in the first process, after the workpiece 140 is installed on the fixing base 121, the pressing plate 122 is driven to ascend or descend by rotating the first screw rod 123, so as to press the workpiece 140 and fix the workpiece 140 on the bearing plate 110;

[0062] The insertion blocks 150 at both ends of the bearing plate 110 are inserted into the insertion grooves 240 on the support table 230, the spring provides elastic force for the abutting block 280, so as to drive the abutting block 280 to abut against the ball 260, so that the ball 260 abuts against the abutting groove 151, thereby fixing the relative position of the insertion block 150 in the insertion groove 240, so that the jig is installed on the four-axis rotary table 221. At this time, the first reference surface of the workpiece 140 is obtained by online measurement of the machine tool, and the measurement result is automatically fed back to the machining program of the machine tool, so that the four-axis rotary table 221 drives the workpiece 140 to move or rotate according to the machining program, and at the same time, the first reference surface of the workpiece 140 is machined by cooperating with the tool;

[0063] When the first process is completed, the air compressor inputs air into the avoidance groove 250 through the air guide channel, so that a large air pressure is generated in the avoidance groove 250. When the air pressure is greater than the elastic force of the spring 291, the abutting block 280 is driven to move towards the groove bottom of the groove 270, so as to drive the ball 260 to move towards the groove bottom of the avoidance groove 250. The insertion block 150 can be separated from the insertion groove 240, so as to replace another set of jigs installed on the four-axis rotary table 221, thereby improving the processing efficiency of the workpiece 140;

[0064] At the same time, when a batch of workpieces 140 are processed in the first process, the first clamping assembly 120 is removed and clamped on the second clamping assembly 130 for the second process. At this time, the first clamping assembly 120 can clamp a new batch of workpieces 140 for the first process, thereby improving the utilization rate of the jig, so that more workpieces 140 can be processed in a single machine tool processing, thereby improving the processing efficiency of the workpiece 140;

[0065] When the second process is processed, the workpiece 140 is accommodated between the two clamping plates 132, and the positioning hole 141 formed by the first process is aligned with the positioning head 135 on the support seat 131, so that the workpiece 140 is positioned, and then the second screw 1341 is rotated to be screwed with the second screw hole, and then the pressing block 1342 is inserted into the limiting groove 1344, and the end of the pressing block 1342 is abutted against the end of the workpiece 140, so that the workpiece 140 is fixed on the second clamping assembly 130. At this time, the jig is installed on the four-axis rotary table 221 in the same way as described above, the second reference surface of the workpiece 140 is obtained by online measurement of the machine tool, and the measurement result is automatically fed back to the machining program, so that the four-axis rotary table 221 moves or rotates the workpiece 140 according to the machining program, and cooperates with the cutter to process the second reference surface of the workpiece 140.

[0066] The above processing method can process different processes of the workpiece 140 on the same jig, improve the utilization rate and adaptability of the jig, and in the process of replacing the workpiece 140, different groups of jigs can be replaced and processed synchronously, thereby improving the processing efficiency of the workpiece 140.

[0067] Among them, the first process and the second process are provided with four workstations, and the workpieces 140 clamped in different workstations are different in size, so that the workpiece 140 can select the appropriate workstation according to the size, thereby improving the adaptability of the first clamping assembly 120 and the second clamping assembly 130 to the workpiece 140.

[0068] The online measurement of the machine tool also uses trigonometric function calculation to automatically rotate and adjust the workpiece 140, thereby reducing the inclination of the workpiece 140 after clamping, and reducing the misalignment during compression and fixation, thereby improving the quality of workpiece processing.

[0069] At the same time, during processing, the features with strict size requirements on the workpiece 140 are processed first, and then the features with large excess on the workpiece 140 are processed, so as to reduce the loosening of the workpiece 140 during processing of the features with large excess.

[0070] The above are preferred embodiments of the present application, which do not limit the protection scope of the present application, therefore: any equivalent changes made on the structure, shape, principle of the present application shall be covered within the protection scope of the present application.
