To achieve the purpose of inspecting the flatness of parts surfaces, gauges are generally composed of modules such as clamping mechanism, inspection mechanism, positioning mechanism, support mechanism and auxiliary mechanism. Each mechanism module is usually designed and installed independently on the inspection platform, which makes the operation of the gauge more complicated. At the same time, it increases the size of the gauge, making it larger and more inconvenient to use, thus increasing the inspection cost.
[0003] Therefore, how to improve the convenience of parts inspection has become a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation
[0026] The core of this application is to provide a parts inspection mechanism to improve the convenience of parts inspection.
[0027] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0028] In related fields, gauges are commonly used to inspect the flatness of parts surfaces. To achieve the purpose of inspecting the flatness of parts surfaces, gauges are generally composed of modules such as clamping mechanism, inspection mechanism, positioning mechanism, support mechanism and auxiliary mechanism. Each mechanism module is usually designed and installed independently on the inspection platform, which makes the operation of the gauge more complicated. At the same time, it increases the size of the gauge, making it larger and more inconvenient to use, thus increasing the inspection cost.
[0029] Therefore, such as Figure 1 As shown in the figure, this application discloses a part inspection mechanism 100, including a fixture connector 10, a pressure head assembly 20, a locking assembly 30, and a surface inspection component 40. By integrating a clamping mechanism, an inspection mechanism, and a positioning mechanism, no additional flipping mechanism is needed for inspection, reducing the complexity of the fixture. The prefabricated structure allows for easy replacement of worn parts, effectively reducing the design difficulty and complexity of the fixture. Furthermore, the surface inspection component 40 is a detachable structure, allowing for installation and inspection at any time when needed, improving the convenience and safety of the inspection operation.
[0030] The following will combine Figure 1 and Figure 2 The parts inspection mechanism 100 disclosed in the embodiments of this application will be explained and described in detail.
[0031] like Figure 1 and Figure 2 As shown, the fixture connector 10 may be provided with at least two positioning posts 11, that is, the number of positioning posts 11 may be two, three or more. The pressure head assembly 20 may include a positioning member 21 and a pressure head member 22. The positioning member 21 may be provided with positioning holes 211 adapted to the positioning posts 11, that is, two, three or more positioning holes 211 may be used corresponding to the positioning posts 11, so that the positioning posts 11 can be inserted into the positioning holes 211, thereby realizing the installation and positioning of the pressure head assembly 20. Multiple pressure head members 22 may be used, that is, two, three or more pressure head members 22 may be used, and each pressure head member 22 may be spaced apart on the positioning member 21. The pressure head assembly 20 and the fixture connector 10 can be locked by the locking member 30, and the pressure head member 22 can press the surface of the part 200. At this time, the profile detection component 40 can be detachably connected to the positioning component 21 by fasteners such as bolts, and the profile clearance of the part 200 at the location of the profile detection component 40 can be measured using a gap gauge. The profile detection component 40 can be detachably connected to the positioning component 21 so that the position of the profile detection component 40 can be adjusted, thereby measuring the profile clearance of the part 200 at different positions.
[0032] In some embodiments, such as Figure 1As shown, the positioning element 21 can be a cylindrical structure, and two positioning posts 11 can be used. The positioning posts 11 can be inserted into the fixture connector 10. The positioning element 21 can have two positioning holes 211 corresponding to the positioning posts 11. The positioning holes 211 can be through holes that pass through the positioning element 21, so that the positioning holes 211 of the positioning element 21 can be aligned with the positioning posts 11 on the fixture connector 10 for positioning and installation.
[0033] In some embodiments, such as Figure 2 As shown, a positioning sleeve 13 for mounting a positioning post 11 can be provided on the fixture connector 10. Two positioning sleeves 13 can be used to fit the positioning post 11 so that the positioning post 11 can be inserted into the positioning sleeve 13, thereby realizing the installation between the positioning post 11 and the fixture connector 10. At the same time, a movable sleeve 2111 for passing through the positioning post 11 can be provided in the positioning hole 211 so that the positioning post 11 on the fixture connector 10 can be inserted into the movable sleeve 2111. This can reduce the wear of the positioning post 11 on the fixture connector 10 and the positioning member 21, and extend the service life of the fixture connector 10 and the positioning member 21.
[0034] In some embodiments, such as Figure 1 As shown, three pressure head components 22 can be used, and the three pressure head components 22 can be distributed at intervals along the circumference of the positioning component 21. At the same time, the included angle between any two adjacent pressure head components 22 can be 120°, that is, the three pressure head components 22 can be evenly distributed at intervals along the circumference of the positioning component 21. Of course, the included angle between any two adjacent pressure head components 22 can also be different. For example, two of the three pressure head components 22 can be arranged collinearly, and the other can be arranged perpendicular to the above two. The specific arrangement can be determined according to the actual size of the part 200.
[0035] The part inspection mechanism 100 disclosed in this application can achieve the installation and positioning of the pressure head assembly 20 by cooperating with the positioning hole on the positioning member 21 and the positioning post 11 on the fixture connector 10. The pressure head assembly 20 and the fixture connector 10 can be locked by the locking assembly 30, and the pressure head member 22 of the pressure head assembly 20 presses against the surface of the part 200. At this time, the surface clearance at the location of the surface inspection member 40 can be measured using a clearance gauge.
[0036] The part inspection mechanism 100 disclosed in this application integrates a clamping mechanism, an inspection mechanism, and a positioning mechanism, eliminating the need for an additional flipping mechanism for inspection and reducing the complexity of the inspection fixture. By adopting an assembly structure, worn parts can be easily replaced, effectively reducing the design difficulty and complexity of the inspection fixture. At the same time, the surface inspection component 40 has a detachable structure, which allows it to be installed and inspected at any time when inspection is required, improving the convenience and safety of the inspection operation.
[0037] In some embodiments, such as Figure 1As shown, the pressure head 22 may include a pressure head 221 and a connecting block 222. The pressure head 221 may be connected to one end of the connecting block 222 so that the surface of the part 200 can be pressed through the pressure head 221. At the same time, the other end of the connecting block 222 may be detachably connected to the positioning member 21 by fasteners such as bolts, so that the pressure head 22 can be fixed on the positioning member 21.
[0038] In some embodiments, such as Figure 1 As shown, the connecting block 222 can adopt a cuboid structure, and the pressure head 221 can include a connecting screw 2211 and a pad 2212. The pad 2212 can be fixed to one end of the connecting screw 2211, so that it can contact the surface of the part 200. At the same time, the other end of the connecting screw 2211 can be threaded to one end of the connecting block 222 and can be locked and fixed by the lock nut 2213 to realize the connection and fixation between the pressure head 221 and the connecting block 222.
[0039] In some embodiments, such as Figure 1 As shown, the pad 2212 can be made of plastic to prevent damage to the surface of the part 200 when the pad 2212 is pressed against the part 200. For ease of understanding, the pad 2212 has a first end and a second end that are arranged opposite to each other, wherein the first end of the pad 2212 is the large-diameter end and the second end of the pad 2212 is the small-diameter end. Meanwhile, the outer diameter of the pad 2212 gradually decreases from the first end (large diameter) to the second end (small diameter), and the end face of the second end (small diameter) of the pad 2212 can contact the surface of the part 200 to reduce the contact area between the pad 2212 and the part 200, further reducing the risk of damage to the surface of the part 200 caused by the pad 2212. The diameter of the first end (large diameter) of the pad 2212 can be larger than the outer diameter of the connecting screw 2211, and the first end (large diameter) of the pad 2212 can contract towards the connecting screw 2211 to achieve connection with the connecting screw 2211, effectively reducing the risk of breakage between the pad 2212 and the connecting screw 2211 due to concentrated stress. It should be noted that the connecting screw 2211 and the pad 2212 can be connected by a detachable threaded connection or by an integral structure; this is not limited here.
[0040] In some embodiments, such as Figure 2As shown, the locking assembly 30 may include a locking screw 31. A limiting part 311 may be provided at one end of the locking screw 31, and the outer diameter of the limiting part 311 may be larger than the outer diameter of the locking screw 31. Simultaneously, a through hole capable of passing through the locking screw 31 may be provided at the center position of the positioning member 21. The outer diameter of the limiting part 311 must be larger than the diameter of the through hole so that the limiting part 311 can abut against the positioning member 21. Thus, the other end of the locking screw 31 can be threadedly connected to the fixture connector 10, thereby achieving the locking of the pressure head assembly 20 and the fixture connector 10 through the locking assembly 30.
[0041] In some embodiments, such as Figure 1 and Figure 2 As shown, the locking assembly 30 may further include a locking handle 32, which may be located at the end of the locking screw 31 away from the fixture connector 10, so that by rotating the locking handle 32, the locking screw 31 can be driven to achieve a threaded connection with the fixture connector 10. The locking handle 32 may be welded to the locking screw 31, or it may be threadedly connected to the locking screw 31; this is not limited to these specific details.
[0042] In some embodiments, such as Figure 2 As shown, a locking sleeve 12 may be provided on the fixture connector 10, and the locking sleeve 12 is provided with an internal thread so that the locking screw 31 can be threadedly connected with the internal thread of the locking sleeve 12, thereby reducing the wear on the fixture connector 10 and extending the service life of the fixture connector 10.
[0043] In some embodiments, such as Figure 2 As shown, the part inspection mechanism 100 may also include a support member 50, and the support member 50 may be disposed between the fixture connector 10 and the positioning member 21, so that a reserved gap that can accommodate the part 200 can be formed between the fixture connector 10 and the positioning member 21.
[0044] In some embodiments, such as Figure 2 As shown, the fixture connector 10 may be provided with a countersunk hole, and the locking sleeve 12 may be inserted into the countersunk hole so that the locking screw 31 can be threadedly connected with the locking sleeve 12. At the same time, the support member 50 may be located in the countersunk hole and protrude from the surface of the fixture connector 10, so that a reserved gap can be formed between the fixture connector 10 and the positioning member 21 to accommodate the part 200, thereby facilitating the measurement of the surface clearance of the part 200.
