[0029] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to be used to explain the present invention, but cannot be understood as limiting the present invention.

[0030] Please refer to the following Figures 1 to 4 The following describes a tooling inspection tool according to an embodiment of the utility model.

[0031] like Figures 1 to 4As shown, the tooling inspection tool according to the embodiment of the utility model comprises: a workbench 1, a fixing block 2 and a detection assembly 3, the workbench 1 is provided with a plurality of mounting positions 11 for fixing different tools 6, there is at least one fixing block 2, and the fixing block 2 is arranged on any one of the plurality of mounting positions 11 for fixing the tooling 6. The detection assembly 3 comprises a controller (not shown) and a sensor assembly 31, the sensor assembly 31 is arranged on the workbench 1, the tooling 6 has a positioning pin 61 to be measured, the sensor assembly 31 is used to measure the deviation between the actual position of the positioning pin 61 to be measured and the target position, and the controller is electrically connected to the sensor assembly 31 to process the measurement data of the sensor assembly 31.

[0032] It should be noted that the target position of the positioning pin 61 is the initial position of the positioning pin 61 of the standard tool 6. In other words, the target position of the positioning pin 61 is the position of the positioning pin 61 when there is no error.

[0033] After the tooling 6 is used for a long time, the measured positioning pin 61 will be deformed to a certain extent, which will cause a certain deviation between the actual position and the target position of the measured positioning pin 61. The sensor assembly 31 can load the target position of the measured positioning pin 61 before measurement, so that when the sensor assembly 31 measures the actual position of the measured positioning pin 61, the deviation between the actual position and the target position of the measured positioning pin 61 can be obtained.

[0034] According to the tooling inspection fixture of the embodiment of the utility model, since a plurality of mounting positions 11 for fixing different tools 6 are provided on the workbench 1, the fixing block 2 can be connected to any one of the plurality of mounting positions 11, thereby different types of tools 6 can be fixed by the tooling inspection fixture, and the positions of the measured positioning pins 61 of different types of tools 6 can be measured by the sensor assembly 31. Therefore, the tooling inspection fixture of the embodiment of the utility model can detect different tools 6, which is beneficial to reducing production and maintenance costs.

[0035] It is understandable that each group of mounting positions corresponds to a different type of tooling 6, and multiple groups of mounting positions 11 can be arranged in different forms to correspond to different types of tooling 6. Since the tooling gauge of the embodiment of the utility model can take into account the measurement of different tooling 6, it is not necessary to set up multiple gauges in a targeted manner, thereby reducing the occupied space of the tooling gauge. In addition, the tooling gauge of the embodiment of the utility model uses the sensor assembly 31 to measure the position of the positioning pin 61 to be measured, which can improve the accuracy of the tooling 6 detection compared to manual measurement, and is conducive to saving measurement time and improving measurement efficiency.

[0036] The fixing block 2 may be one or more. In the example of the present application, there are multiple fixing blocks 2, thereby improving the reliability of the positioning of the tooling 6 and improving the measurement accuracy. For example, the tooling 6 is provided with multiple main positioning pins 62, and the multiple main positioning pins 62 are plugged into different fixing blocks 2, thereby fixing the tooling 6.

[0037] Optionally, each group of mounting positions 11 includes at least one sub-mounting position 111, and the sub-mounting position 111 is used to connect with the main positioning pin 62 of the tool 6. It can be understood that each group of mounting positions 11 has one or more sub-mounting positions 111. For example, when the structure of the tool 6 is relatively large (when the number of main positioning pins 62 is relatively large), a relatively large number of sub-mounting positions 111 can be arranged, thereby ensuring the reliability of the positioning of the tool 6. When the structure of the tool 6 is relatively small (when the number of main positioning pins 62 is relatively small), a relatively small number of sub-mounting positions 111 can be arranged, thereby saving the production cost of the tooling inspection fixture.

[0038] like Figure 1 and Figure 3 As shown, the number of fixed blocks 2 is less than the number of mounting positions 11, and the fixed blocks 2 are detachably connected to the mounting positions 11, for example, the fixed blocks 2 are connected to the mounting positions 11 by screws. It can be understood that a plurality of fixed blocks 2 correspond to some mounting positions 11 one by one, and since the fixed blocks 2 are detachably connected to the mounting positions 11, when the tooling gauge needs to measure other tools 6, the relative positions of the plurality of fixed blocks 2 and the mounting positions 11 can be switched so that the fixed blocks 2 can fix different tools 6. Since the number of fixed blocks 2 is less than the number of mounting positions 11, the number of parts of the tooling gauge can be reduced while ensuring the reliable positioning of the tooling 6, thereby reducing the production cost of the tooling gauge.

[0039] In some embodiments, the position of the sensor assembly 31 relative to the workbench 1 is adjustable to measure the different positions of the positioning pins 61. It is understandable that when it is necessary to measure the position of a certain positioning pin 61, the sensor assembly 31 can be moved to the position, thereby reducing the number of sensor assemblies 31 and reducing the production cost of the tooling inspection tool.

[0040] In one example, a plurality of measuring positions 12 are provided on the workbench 1, and different measuring positions 12 correspond to different positioning pins 61 to be measured. A sliding portion (not shown) is provided on the workbench 1, and the plurality of measuring positions 12 are all arranged on an extension path of the sliding portion. The position of the sensor assembly 31 along the extension direction of the sliding portion is adjustable to measure the positioning pins 61 to be measured corresponding to different measuring positions 12. This makes it convenient for the sensor assembly 31 to measure the positioning pins 61 to be measured at different positions, thereby reducing the number of arrangements of the sensor assembly 31 and reducing the production cost of the tooling inspection fixture.

[0041] In another example, if Figure 1 and Figure 3 As shown, a plurality of measuring positions 12 are provided on the workbench 1, and different measuring positions 12 correspond to different positioning pins 61 to be measured, and there is at least one sensor assembly 31, and the sensor assembly 31 is detachably connected to the measuring position 12. It can be understood that, since the sensor assembly 31 is detachably connected to the measuring position 12, the sensor assembly 31 can be installed at different measuring positions 12 to detect the positioning pins 61 to be measured at different positions.

[0042] In some embodiments, Figure 1 As shown, the sensor assembly 31 includes a first sensor 311 and a second sensor 312. The first sensor 311 and the second sensor 312 can be detachably mounted on the same measuring station 12. The first sensor 311 is used to measure the deviation between the actual position of the positioning pin 61 to be measured along the first direction and the target position. The second sensor 312 is used to measure the deviation between the actual position of the positioning pin 61 to be measured along the second direction and the target position. The first direction, the second direction and the thickness direction of the workbench 1 are orthogonal to each other. For example, Figure 2 As shown, the first direction may be the X direction, the second direction may be the Y direction, and the first sensor 311 and the second sensor 312 may both be displacement sensors. The first sensor 311 is used to measure the deviation of the measured positioning pin 61 along the X direction, and the second sensor 312 is used to measure the deviation of the measured positioning pin 61 along the Y direction. The controller communicates with external measurement software, thereby uploading the measurement data of the first sensor 311 and the second sensor 312 to the measurement system.

[0043] In another example, if Figure 2 and Figure 3 As shown, the sensor assembly 31 may only include the first sensor 311. After the first sensor 311 measures the position of the positioning pin 61 to be measured along the first direction, the first sensor 311 is removed and installed to the corresponding position to measure the position of the positioning pin along the second direction. In other words, the tooling inspection tool of the embodiment of the utility model can use one sensor (the first sensor 311) to complete the measurement of the tooling 6, thereby further reducing the production cost of the tooling inspection tool.

[0044] In some embodiments, Figure 2As shown, the detection assembly 3 also includes an adjustment member 32 and a fixed platform 33, the adjustment member 32 is mounted on the measuring position 12, the fixed platform 33 is mounted on the adjustment member 32 and the position relative to the adjustment member 32 is adjustable, and the sensor assembly 31 includes a first sensor 311, and the first sensor 311 is detachably mounted on the fixed platform 33. It can be understood that since the actual position of the measured positioning pin 61 of different tooling 6 is different from the target position (initial position) of the measured positioning pin 61, the operator needs to adjust the position of the first sensor 311 to measure the measured positioning pin 61 more accurately. In other words, after the tooling 6 is fixed, the adjustment member 32 and the fixed platform 33 can be used to bring the first sensor 311 close to the measured positioning pin 61. After the measurement is completed, the first sensor 311 is separated from the measured positioning pin 61 by using the adjustment member 32 and the fixed platform 33, thereby improving the convenience of using the tooling inspection tool.

[0045] In one example, if Figure 2 As shown, the adjusting member 32 is a slide rail, which extends in the direction toward the detection block 34. The fixing platform 33 is installed on the slide rail and its position relative to the slide rail is adjustable along the length direction of the slide rail, thereby facilitating the adjustment of the position movement of the first sensor 311, and the structural design is simple and easy to disassemble and assemble.

[0046] Alternatively, if Figure 2 As shown, the detection assembly 3 also includes a detection block 34, which is installed on the workbench 1. The detection block 34 is provided with a positioning hole 341 for inserting the positioning pin 61 to be measured. The detection block 34 is provided with a measuring plane 342 on the side facing the first sensor 311, and the first sensor 311 is against the measuring plane 342. It can be understood that since the positioning pin 61 to be measured is cylindrical, that is, the measured surface of the positioning pin 61 to be measured is a curved surface, when the first sensor 311 detects the positioning pin 61 to be measured, there is a problem of inaccurate positioning. Therefore, the positioning pin 61 to be measured can be inserted into the positioning hole 341 of the detection block 34, and the first sensor 311 can measure the value of the measuring plane 342 of the detection block 34 to indirectly measure the position of the positioning pin 61 to be measured, which is conducive to improving the measurement accuracy.

[0047] like Figure 2As shown, in order to reduce the error caused by the relative rotation between the detection block 34 and the positioning pin 61 to be measured, a plurality of marking positions 343 can be provided on the measurement plane 342 along a preset direction, and the position of the first sensor 311 relative to the fixed platform 33 along the preset direction can be adjusted so that the first sensor 311 can measure the positions of different marking positions 343. For example, there are two marking positions 343 and they are symmetrically arranged on the measurement plane 342. It can be understood that when measuring the detection block 34 (in the X direction or Y direction), the needle of the first sensor 311 is contacted with a marking position 343 of the detection block 34, and the value of one marking position 343 is obtained, and the value of another marking position 343 is measured in the same way. After the measurement is completed, the measurement software can automatically obtain the center point deviation through the two values, thereby improving the accuracy of the position measurement.

[0048] Optionally, the first sensor 311 is magnetically attracted to the fixed table 33, which makes it convenient for the operator to disassemble and adjust the first sensor 311, which is beneficial to improving the efficiency of the measurement of the tooling 6. Furthermore, the detection block 34 is magnetically attracted to the workbench 1, so when the operator needs to adjust the position of the detection block 34, only a certain external force is required to separate the detection block 34 from the workbench 1, so that the position adjustment of the detection block 34 can be made more convenient. In addition, due to the magnetic attraction between the detection block 34 and the workbench 1, the detection block 34 can be prevented from moving randomly during measurement, which is beneficial to ensure the accuracy of the measurement.

[0049] In some embodiments, Figure 1 and Figure 3 As shown, the tooling inspection tool also includes a display screen 4, which is arranged on the workbench 1 and is electrically connected to the controller. It is understandable that the sensor assembly 31 can upload the measured data to the display screen 4 after being processed by the controller to improve the visualization and intelligence of the tooling inspection tool.

[0050] Alternatively, if Figure 1 and Figure 3 As shown, the tooling inspection tool further includes a mobile frame 5, the lower end of the mobile frame 5 has a roller 51, and the workbench 1 is arranged at the upper end of the mobile frame 5. This makes it convenient for operators to transport the tooling inspection tool, thereby improving the convenience of using the tooling inspection tool.

[0051] In the embodiment of the present application, the tooling inspection tool can use the sensor assembly 31 to quickly measure the position deviation of the measured positioning pin 61 of the tooling 6, and can automatically upload the data to the measurement system, which can be viewed in real time using the display screen 4, and the deviation trend can be viewed based on big data to provide early warning. The sensor assembly 31 can switch different positions on the workbench 1 to measure the measured positioning pin 61 at different positions; the fixed block 2 can be switched on the workbench 1, thereby achieving the purpose of measuring different tools 6.
