[0002] A sheet metal part is a part made of metal plates, which is commonly used in different products in industrial design. The characteristics of non-standard parts make its application very extensive.

[0003] Among the existing types of sheet metal parts, the sill connecting plate is a relatively special sheet metal part. Its surface is strip-shaped and both ends are provided with holes for bolts to pass through. When detecting the sill connecting plate, it will be placed on the inspection tool. The existing inspection tool detects the holes on the surface of the sill connecting plate, and inserts the detected lead rod into the holes of the sill connecting plate, so as to measure whether the holes meet the specifications.

[0004] In the detection process of the sill beam connecting plate, since the inspection tool can only detect one direction and one hole diameter, it is necessary to continuously adjust the installation position of the sill beam connecting plate during the detection process, and the detection process needs to be adjusted many times, which is time-consuming and laborious. Therefore, the hole diameter detection of the existing sill beam connecting plate has the problems of cumbersome operation and low efficiency. Content of the Utility Model

[0026] In order to make the purpose, technical solutions and advantages of the present utility model clearer, the following further details the present utility model in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model

[0027] Refer to Figures 1-3 , the inspection tool includes an inspection tool base for fixing the detection and assembly. A telescopic device 2 and a driving device 3 are respectively arranged on the inspection tool base. The telescopic device 2 can drive a detection head to move towards the surface of the sheet metal part for detection, and the driving device 3 can form a linkage effect with the telescopic device 2 and perform detection towards the surface of the sheet metal part together under the drive of the telescopic device 2

[0028] Refer to Figures 1-3, the telescopic device 2 includes a telescopic rod 21. One side of the telescopic rod 21 is rotatably connected to a rotating member 22. One end of the rotating member 22 abuts against one end of the telescopic rod 21. The rotating member 22 is irregular in shape and its surface always contacts the telescopic rod 21. The telescopic device 2 further includes an extending member 24 fixedly arranged at one end of the telescopic rod 21. The surface of the extending member 24 is semi-circular and its surface fits with the surface of the rotating member 22. By the fitting of the semi-circular extending member 24 on the telescopic rod 21 and the surface of the rotating member 22, when the rotating member rotates, the telescopic rod 21 will be driven to perform telescopic movement due to friction. The telescopic device 2 further includes a fixing ring 25 fixedly arranged on the telescopic rod 21. Several telescopic seats 11 are fixedly connected to the fixture base. The telescopic seats 11 can support the surface of the telescopic rod 21 away from the fixture base. The telescopic rod 21 slides through the telescopic seats 11. An elastic member 26 is fixedly connected to the fixing ring 25. One end of the elastic member 26 is fixedly connected to the fixing ring 25 and the other end is fixedly connected to the surface of the telescopic seat 11. When the telescopic rod 21 expands and contracts, the elastic member 26 will be compressed. When the rotating member 22 stops rotating, under the elastic force of the elastic member 26, the telescopic rod 21 will drive the rotating member 22 to return to its original position. A rotating handle 4 is fixedly connected to the rotating member 22, which is convenient for manually controlling the rotation of the rotating member 22.

[0029] Reference Figures 1-3 , a detection plate 27 is fixedly connected to the front end of the telescopic rod 21. A telescopic detection head 28 is fixedly arranged on the detection plate 27. The other end of the telescopic rod 21 is also fixedly connected to a telescopic plate 23. The telescopic plate 23 is fixedly arranged on one side of the detection plate 27. During the telescopic process of the telescopic rod 21, the telescopic plate 23 can be driven to move synchronously, and the telescopic detection head 28 can be driven to move towards the surface of the sheet metal part. Telescopic teeth 32 are provided on the surface of the telescopic plate 23. The telescopic teeth 32 can mesh with a gear to form a linkage relationship, thus ensuring the effect that the telescopic part can drive some structures of the driving part to move synchronously.

[0030] Reference Figures 1-3 , the driving structure includes a driving gear 31. The driving gear 31 is rotatably connected to the fixture base and can form a meshing relationship with the telescopic teeth 32. When the telescopic plate 23 moves, the telescopic gear will be driven to rotate. A driving rod 33 is meshed on the opposite side of the driving gear 31 and the telescopic rod 21. The movement direction of the driving rod 33 is opposite to that of the telescopic rod 21. When the telescopic rod 21 extends forward, the driving rod 33 will move towards the direction of the telescopic rod 21. Several driving seats 12 are fixedly arranged on the detection base 1. The driving rod 33 passes through several driving seats 12. A driving plate 34 is fixedly arranged at the front end of the driving rod 33. A driving detection head 35 is fixed on the driving plate 34, which can synchronously move the driving detection head 35 in the opposite direction to the telescopic detection head 28. Through the linkage of the driving gear 31, the mechanism can perform synchronous detection on two surfaces of the sheet metal part.

[0031] When using this mechanism, the sheet metal is placed on the placement table 13 and fixed, with the surface of the sheet metal facing the drive detection head 35 and the telescopic detection head 28. At this time, the rotating handle 4 is turned, and the drive detection head 35 and the telescopic detection head 28 will synchronously detect the surface of the sheet metal. The drive detection head 35 and the telescopic detection head 28 will contact the surface of the sheet metal. After the rotating handle 4 is released, under the rebound force of the elastic member 26, the drive detection head 35 and the telescopic detection head 28 will move away from the surface of the sheet metal. At this time, the sliding cylinder 16 is started, the placement table 13 will slide on the sliding track 14, and the position of the sheet metal will also move. The rotating handle 4 is turned again to perform fixed-point detection on other positions, thereby realizing the process of double-sided multi-point detection.

[0032] The above embodiments are used to further illustrate the present invention, but the present invention is not limited to these specific implementations. Any modification, equivalent replacement and improvement made within the spirit and principle of the present invention should be understood to be within the protection scope of the present invention.
