DETAILED DESCRIPTION

[0056] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It is to be understood that the specific embodiments described herein are only used to explain the relevant invention, rather than to limit the invention. It is also necessary to explain that, for ease of description, only the parts related to the invention are shown in the accompanying drawings.

[0057] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0058] Example 1

[0059] Please refer to Figure 1 and Figure 2 , a workpiece processing system provided in this embodiment includes:

[0060] A reference base 1, at least two of which are provided; an absolute coordinate system is preset on the reference base 1;

[0061] The deviation measuring module 2 has a reference base 1 built therein, and the reference base 1 can be matched with a clamping base 3; the clamping base 3 has a workpiece coordinate system and the clamping base 3 has a clamping end capable of clamping a workpiece to be processed; the deviation measuring module 2 is configured to measure the deviation value between the workpiece coordinate system and the absolute coordinate system;

[0062] a compensation module, the compensation module being configured to receive the deviation value and generate compensation information;

[0063] A processing module, wherein the processing module has main processing information built therein, and the processing module is further configured to receive compensation information and generate information to be processed; the information to be processed includes: main processing information and compensation information;

[0064] A processing machine tool 4, wherein the processing machine tool 4 has a reference base 1 built therein, and the reference base 1 can be matched with a clamping base 3; the processing machine tool 4 comprises:

[0065] A control module, the control module is configured to obtain the information to be processed and generate a processing instruction;

[0066] The driving module 5 is configured to execute a processing instruction to process the workpiece to be processed.

[0067] In this workpiece processing system, since the reference base 1 is respectively provided on the processing machine 4 and in the deviation measurement module 2 for matching the clamping base 3, before processing each workpiece, it can be first fixed on the clamping base 3, and then the clamping base 3 is connected to the reference base 1 in the deviation measurement module 2. After measuring the deviation value, the processing instruction is generated by the compensation module, the processing module and the control module, and input into the driving module 5, and then the clamping base 3 with the above workpiece fixed is taken out from the deviation measurement module 2 and placed on the processing machine 4 in a set direction, and finally the driving module 5 performs the processing operation on the part. This processing system can move the measurement process of the deviation value to the outside of the processing machine 4. For a large number of workpieces with different processing requirements, the measurement of their deviation values ​​can be completed in advance. In large-scale processing and production, the interval preparation time required for changing workpieces is greatly reduced, and the processing efficiency of the processing machine 4 can be significantly improved.

[0068] In a preferred embodiment for improving machining accuracy, the reference base 1 has a first mating end, the clamping base 3 has a second mating end, and a detachable connection structure and a position locking mechanism are provided between the first mating end and the second mating end.

[0069] Since the detachable connection structure is provided between the first mating end and the second mating end, the process of removing the clamping base 3 fixed with the workpiece to be processed from the reference base 1 in the deviation measurement module and moving it to the reference base 1 on the processing machine 4 is more convenient. In addition, since the position locking mechanism is provided between the first mating end and the second mating end, the clamping base 3 and the reference base 1 can be connected more firmly. This can effectively prevent the clamping base 3 from being separated from the reference base 1 during the processing of the workpiece, thereby improving the accuracy of the deviation measurement module 2 in measuring the deviation value and improving the processing accuracy of the drive module 5 on the workpiece.

[0070] In a preferred embodiment to further improve the processing accuracy, an anti-rotation structure is further provided between the first mating end and the second mating end, including:

[0071] A first clamping member 11, wherein there are a plurality of first clamping members 11, and all of the first clamping members 11 are disposed on the first matching end;

[0072] There are a plurality of second clamping members 31 , which are disposed on the second matching end and are used for clamping and cooperating with the corresponding first clamping members 11 .

[0073] like Figure 3 and Figure 4 As shown in the figure, the clamping fit between the first clamping part 11 on the first mating end and the second clamping part 31 on the second mating end can effectively prevent relative rotation between the clamping base 3 and the reference base 1, so that the workpiece remains in the set position, the measurement result of the deviation value will be more accurate, and the accuracy of the processed workpiece will also be higher.

[0074] In a preferred embodiment of the position locking mechanism, the first mating end is provided with a first groove 101, the inner wall of the first groove 101 is provided with a plurality of first through holes 102, the first mating end is further provided with a plurality of locking spaces 103, the side walls of the locking spaces 103 are provided with second through holes 104, the first groove 101 is connected with each locking space 103 through each of the first through holes 102, the second mating end is provided with a first protrusion 301, the side wall of the first protrusion 301 is provided with a second groove 302,

[0075] The position locking mechanism comprises:

[0076] A locking ball 61, wherein the locking ball 61 is disposed in the first through hole 102, and the locking ball 61 can move between a first station and a second station. When the locking ball 61 is in the first station, one end of the locking ball 61 can be matched with the second groove 302, and the second matching end is in a clamping state with the first matching end; when the locking ball 61 is in the second station, the second matching end is in a non-clamping state with the first matching end;

[0077] A locking member 62, the locking member 62 is disposed in the locking space 103, and has a second protrusion 621 thereon. The locking member 62 can move between a third station and a fourth station. When the locking member 62 is in the third station, the second protrusion 621 is used to abut the locking ball 61 against the first station; when the locking member 62 is in the fourth station, the locking ball 61 can move from the first station to the second station;

[0078] An elastic member 63, which is also disposed in the locking space 103 and between the locking member 62 and an inner wall of the locking space 103, and is used to apply a force along a first direction to the locking member 62, wherein the first direction is perpendicular to an extension direction of the first through hole 102;

[0079] A pneumatic device, the output end of which is connected to each of the second through holes 104, for applying a force to the locking member 62 along a second direction, the second direction being opposite to the first direction;

[0080] The elastic member 63 cooperates with the pneumatic device to switch the state of the position locking mechanism. When the position locking mechanism is in a locked state, the locking member 62 is located at the third position; when the position locking mechanism is in a released state, the locking member 62 is located at the fourth position.

[0081] like Figure 5 As shown in , during the process of installing the clamping base 3 onto the reference base 1, since the pneumatic device is not turned on, during the process of inserting the first protrusion 301 on the second matching end into the first groove 101 on the first matching end, the second protrusion 621 on the locking member 62 is always in contact with the locking ball 61, and the locking ball 61 is always located in the first station. After the first protrusion 301 is inserted into the first groove 101, the other end of the locking ball 61 is engaged with the second groove 302, and the locking member 62 is located in the third station. The first matching end and the second matching end are in an engaged state, and the position locking mechanism is in the locked state; as shown in Figure 6As shown in, in the process of removing the clamping base 3 from the reference base 1, the pneumatic device is controlled to fill the locking space 103 with gas through the second through hole 104, and drives the locking member 62 to compress the elastic member 63. The locking member 62 is located in the fourth station, and the second protrusion 621 and the locking ball 63 are no longer abutted. When the first protrusion 301 is removed from the first groove 101, the locking ball 61 can be moved from the first station to the second station, the first mating end and the second mating end are in a non-clamping state, and the position locking mechanism is in the released state.

[0082] In a preferred embodiment for improving the ease of use of the workpiece processing system, an input module is also included, the input module includes a first barcode scanner and a second barcode scanner, the first barcode scanner is configured to convert the information to be processed into a first two-dimensional code, and scan the first two-dimensional code onto the clamping base 3; the second barcode scanner is configured to scan the first two-dimensional code, and convert the first two-dimensional code into the information to be processed and transmit it to the control module.

[0083] The information to be processed is converted into the first two-dimensional code by the first barcode scanner and scanned onto the clamping base 3, and then the clamping base 3 holding the workpiece to be processed is fixed onto the reference base 1 on the processing machine 4, and then the information on the first two-dimensional code is scanned to the control module by the second barcode scanner to control the processing of the workpiece by the driving module 5. In this way, when switching the clamping base holding the workpiece with different processing requirements, it can be faster and more convenient, which improves the convenience of use of the workpiece processing system.

[0084] In a preferred embodiment to further improve the usability of the workpiece processing system, the input module further includes:

[0085] An input device, the input device being configured to input call information;

[0086] A third barcode scanner, the third barcode scanner is configured to receive the call information, convert it into a second two-dimensional code, and scan it onto the reference base;

[0089] The control module is also configured to execute the calling instruction to call the information to be processed and convert it into the processing instruction.

[0090] Since the processing instructions corresponding to workpieces with different processing requirements are different, the programs used to convert the processing information into the processing instructions may also be different. Therefore, through the cooperation of the input device, the third barcode scanner and the second barcode scanner, different calling information can be conveniently input into the control module for executing the above operations.

[0091] In a preferred embodiment of improving the anti-misoperation performance of the workpiece processing system, the input device is further configured to input and set foolproof information;

[0095] It is better than the third barcode scanner converting the fool-proof information used to delete the compensation information into the third QR code and scanning it onto the reference base 1, so that the second barcode scanner can scan the fool-proof information into the control module. After the drive module 5 executes the processing instruction, other redundant operation information is input into the control module, and the workpiece processing system will not cause any misoperation, thereby effectively improving the yield of workpiece processing and saving costs.
