[0002] Gauge standard parts are widely used in a variety of fields, including automotive manufacturing, mold making, and machining. In particular, during the automotive manufacturing process, various gauge standard parts are used to inspect parameters such as the size, shape, position, and quality of automotive parts to ensure they meet design requirements. Furthermore, during vehicle maintenance, gauge standard parts are also used to check the wear, assembly quality, and operating status of automotive parts.

[0003] In addition, the application document with publication number CN217900813U mentions an auxiliary positioning device for an exclusive product online inspection fixture. The device has a positioning component, and the standard part is installed on the second pad. A number of adjustable shafts running through the mesh plate are used to measure the shape of the standard part, and the part to be tested is installed on the first pad. The part to be tested contacts the contact sensors on the several shafts, and the part to be tested can be inspected. For products with exclusive shapes, the detection effect is good, the adjustment is convenient, and the application range is wide. However, there are still certain defects that need to be optimized. The specific defects are as follows: the operation of the device is relatively cumbersome, which reduces the detection effect.

[0004] Therefore, it is particularly important to design an auxiliary positioning device for the standard parts of the inspection fixture to change the above technical defects and improve the overall practicality. Utility Model Content

[0005] The purpose of the present utility model is to provide an auxiliary positioning device for a gauge standard part, so as to solve the problems raised in the above background technology.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] An auxiliary positioning device for a gauge standard part comprises a workbench, a fixed frame symmetrically provided on the top of the workbench, a slot provided inside the fixed frame, a CCD camera assembly provided inside the slot, a first vertical frame provided on the top of the workbench, a second vertical frame provided on one side of the first vertical frame, a plurality of first electric push rods provided inside the first vertical frame, an extrusion plate provided at the output ends of the plurality of first electric push rods, a first fixed block symmetrically provided on the extrusion plate, a plurality of second electric push rods provided inside the second vertical frame, a second fixed block symmetrically provided at the output ends of the plurality of second electric push rods, a laser beam emitter provided inside the second fixed block, a first laser rangefinder provided on the top of the first and second fixed blocks, and a second laser rangefinder provided on the inner side walls of the first and second vertical frames.

[0014] 1. In the utility model, an auxiliary positioning device for a gauge standard part is provided, and the structure of an extrusion plate, a fixed block, an electric push rod, a laser beam emitter, and a displacement sensor is utilized. By placing the workpiece to be tested and the standard part at a predetermined position, the electric push rod is activated to cooperate with the extrusion plate to adjust and fix the positions of the workpiece to be tested and the standard part. During this period, a laser rangefinder is used to calibrate the position to keep the distance between the workpiece to be tested and the standard part and the side walls of their respective vertical frames consistent. Then, the laser beam emitter is activated.

[0023] For examples, see Figure 1-3 , the utility model provides a technical solution:

[0024] An auxiliary positioning device for a gauge standard part includes a workbench 1, a fixed frame 101 is symmetrically provided on the top of the workbench 1, a slot 102 is provided inside the fixed frame 101, a CCD camera assembly 103 is provided inside the slot 102, a first vertical frame 2 is provided on the top of the workbench 1, a second vertical frame 3 is provided on one side of the first vertical frame 2, a plurality of first electric push rods 201 are provided inside the first vertical frame 2, an extrusion plate 203 is provided at the output end of the plurality of first electric push rods 201, and a first fixing block 203 is symmetrically provided on the extrusion plate 203 04, a plurality of second electric push rods 301 are provided inside the second vertical frame 3, and a second fixed block 302 is symmetrically provided at the output end of the plurality of second electric push rods 301, a laser beam emitter 303 is provided inside the second fixed block 302, a first laser rangefinder 4 is provided on the top of the first fixed block 204 and the second fixed block 302, and a second laser rangefinder 5 is provided on the inner side wall of the first vertical frame 2 and the second vertical frame 3. By placing the workpiece to be tested and the standard workpiece at the predetermined positions inside the second vertical frame 3 and the first vertical frame 2 respectively, the workpiece is started. The electric push rods inside the two vertical frames drive the squeezing plate 203 to adjust the positions of the workpiece to be tested and the standard part. At the same time, the two sets of first laser rangefinders 4 and second laser rangefinders 5 are used to align the distances to the side walls of the two vertical frames, so that the workpiece to be tested and the standard part reach the predetermined positions, ensuring that their positions are relative and consistent. Then, the laser beam emitter 303 is started. If there is no problem with the dimensions of the workpiece to be tested and the standard part, the laser beam can pass through the perforation to reach the fixed frame 101. At the same time, when the CCD camera components 103 on the two fixed frames 101 take pictures and record, since the positions of the workpiece to be tested and the standard part are relatively overlapped, the two CCD camera components 103 will only capture the relative workpiece to be tested and the standard part. If there is no overlap between the workpiece to be tested and the standard part, that is, if the dimensions of the workpiece to be tested are incorrect, the laser beam will directly hit the first fixed block 203 without passing through the perforation, and the operator can directly observe it with the naked eye. At the same time, the content captured by the two CCD camera components 103 will appear on the workpiece to be tested and the standard part at the same time. At this time, if there is a problem with the workpiece to be tested, the operator can perform relevant operations.

[0025] Among them, four groups of first electric push rods 201 and second electric push rods 301 are respectively provided, and the four groups of first electric push rods 201 and second electric push rods 301 are arranged at equal intervals. The four groups of electric push rods are used to fix the position of the workpiece to be tested or the standard part. A pressure sensor is provided on one side of the extrusion plate 203, and the extrusion plate 203 is provided with an anti-slip coating of polyurethane material to facilitate control of the extrusion force. A perforation is provided inside the first fixed block 204, and the laser beam emitter 303 is adapted thereto to facilitate the laser beam to pass through the perforation to form a straight line. The fixed frame 101, the first vertical frame 2, and the second vertical frame 3 are respectively fixedly connected to the workbench 1. A plurality of supporting legs are provided at the bottom end of the workbench 1 for support, which is convenient for support.

[0026] The working process of the utility model is as follows: when using the auxiliary positioning device for the inspection standard parts, first, the workpiece to be tested and the standard part are placed at the predetermined positions inside the second vertical frame 3 and the first vertical frame 2 respectively, and the electric push rods inside the two vertical frames are started to drive the extrusion plate 203 to adjust and fix the positions of the workpiece to be tested and the standard part. At the same time, the two sets of first laser rangefinders 4 and second laser rangefinders 5 are used to make the distance between the side walls of the two vertical frames consistent, so that the workpiece to be tested and the standard part reach the predetermined position, ensuring that the positions between them are relative and consistent. Then, the laser beam emitter 303 is started. If there is no problem with the size of the workpiece to be tested and the standard part, the laser beam emitter 303 is activated. The light beam can pass through the through hole to reach the fixed frame 101. At the same time, when the CCD camera components 103 on the two fixed frames 101 take pictures and record, since the positions of the test piece and the standard part are relatively overlapped, the two CCD camera components 103 will only capture the relative test piece and standard part. If the test piece and the standard part do not overlap, that is, the size of the test piece is wrong, the laser beam will directly hit the first fixed block 203 without passing through the through hole. The operator can observe it directly with the naked eye. At the same time, the content captured by the two CCD camera components 103 will show the test piece and the standard part at the same time. At this time, if there is a problem with the test piece, the operator can perform relevant operations.

[0027] The standard parts used in this application document can all be purchased from the market, and the specific connection methods of each part adopt conventional means such as mature bolts, rivets, welding, etc. in the existing technology. The machinery, parts and equipment all adopt conventional models in the existing technology. The control method is controlled by a controller, and the control circuit of the controller can be realized through simple circuit connection by technicians in this field. It is common knowledge in this field, so this application document will no longer explain the control method and circuit connection in detail.

[0028] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
