DETAILED DESCRIPTION

[0018] In order to better understand the purpose, structure and function of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement it according to the description.

[0019] It should be noted that the experimental methods described in the following embodiments are conventional methods unless otherwise specified, and the reagents and materials are commercially available unless otherwise specified; in the description of the present invention, the terms "lateral", "longitudinal", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore cannot be understood as a limitation on the present invention.

[0020] like Figure 1 and Figure 2 As shown, the utility model provides an all-round slide rail detection mechanism, including a slide rail moving device 2, a supporting device 4 slidably connected to the slide rail moving device 2, a detection device 9 connected to the supporting device 4 with a connecting block, and a dial indicator arranged on the detection device 9, the slide rail moving device 2 includes a pair of transverse slide rails 21 and a longitudinal slide rail 22, forming an I-shaped structure, the two ends of the longitudinal slide rail 22 are slidably connected to the pair of transverse slide rails 21 and move synchronously along the transverse slide rails 21, the supporting device 4 is slidably connected to the longitudinal slide rail 22, so as to drive the detection device 9 to move in multiple directions, thereby realizing all-round detection of parts through the dial indicator.

[0021] By combining and utilizing the slide rail moving device 2, a three-slide rail mechanism is adopted, two slide rails are placed horizontally, the third slide rail in the longitudinal direction is connected by the slide block 31, and the third slide rail placed vertically is connected to the detection device 9 by the slide block 31. The slide rail placed horizontally drives the slide rail placed vertically to slide, and the longitudinal slide rail 22 drives the detection mechanism to slide, so as to realize multi-directional detection of large-area parts.

[0022] In another embodiment, it also includes a sliding positioning device 3, which includes a reference block 32, a sliding block 31 and a positioning pin 33. The reference block 32 is set in the middle of the transverse slide rail 21 and the longitudinal slide rail 22 and has a plurality of positioning holes arranged at intervals thereon. The two ends of the longitudinal slide rail 22 are slidably connected to the transverse slide rail 21 by setting the sliding block 31. The supporting device 4 is also slidably connected to the longitudinal slide rail 22 by setting the sliding block 31. The above-mentioned sliding blocks 31 are all provided with positioning holes. The positioning pin 33 is connected to the positioning hole on the sliding block 31 and the positioning hole on the reference block 32 to fix the longitudinal slide rail 22 and the supporting device 4.

[0023] The reference block 32 is fixedly provided with positioning holes, and the position remains unchanged. When the entire device slides to the corresponding detection position through the slide rail, the positioning pin 33 is inserted into the positioning holes on the sliding block 31 and the reference block 32 to realize the positioning and fixation of the detection device 9; if all parts of the parts are the same and there is no requirement for the detection position, this positioning device can be omitted and detection can be performed at any position.

[0024] In another embodiment, the support device 4 is vertically arranged on the longitudinal slide rail 22, and the top of the support device 4 is fixedly connected to the detection device 9 through a connecting device 5, and the connecting device 5 is a connecting block.

[0025] In another embodiment, the top of the connecting block has a U-shaped slot, the connecting block is hinged in the U-shaped slot through a pin and locked by a reference positioning locking device 6, the reference positioning locking device 6 is a locking block, which is vertically threaded to the top of the supporting device 4, and the outer periphery of the locking block protrudes from the top surface of the connecting block and is tightly pressed against the connecting block, thereby realizing the locking, positioning and fixation of the connecting block.

[0026] In another embodiment, the detection device 9 is provided with a plurality of detection holes 10, which respectively correspond to a plurality of zeroing devices 7 of different sizes. The zeroing devices 7 cooperate to adjust different zeroing intervals of the dial indicator, and the dial indicator is correspondingly installed in different detection holes.

[0027] Different zeroing devices 7 are set on the bottom plate 1 of the inspection tool, and different zeroing devices 7 are used, and then different dial gauge 8 detection holes 10 are arranged on the detection device 9, so that one detection device 9 can be used for multiple purposes and detect positions at different heights. The zeroing distances of the zeroing device 7 to the dial gauge 8 are different, and different detection holes 10 correspond to different zeroing devices 7, so that after zeroing through different zeroing devices 7, they are placed in the corresponding detection holes 10, and the detectable positions are also different. As many zeroing slots as there are different height positions. Multiple zeroing devices and multiple detection holes are set, and only one dial gauge is set. Reason 1 is space limitation: some detection positions are limited by space and need to control the height of the dial gauge. Reason 2 is standard unification: currently, when using a dial gauge, only one specification will be used when there is no special requirement, that is, a universal dial gauge to ensure the accuracy of the detection result. Reason 3 is diversity: there are many positions at different heights of parts. If all zeroing devices are used, more data will be arranged, and the number of matching in this application will be doubled.

[0028] In another embodiment, it further comprises a gauge base plate 1, and the slide rail moving device 2, the supporting device 4, the detecting device 9 and the zeroing device 7 are all arranged on the gauge base plate 1 to form an integral structure.

[0029] The detection method of the present application is mainly to move the detection device 9 to the part that needs to be detected by moving the sliding block 31 on the sliding rail, lock the part by using the sliding positioning device 3, and then lock the detection device 9 by the reference positioning locking device 6. Even the all-round sliding rail detection mechanism can accurately locate any part that needs to be detected on the part, thereby realizing all-round detection of the part, that is, one mechanism can realize multi-part detection of the part.

[0030] like Figure 3 The figure shows the application of the detection mechanism of the present invention on the door knocker inspection fixture. The lower slide rail moving device 2 drives the movement of the entire detection device 9. Only one sample knife is used to achieve comprehensive inspection of the illustrated part. The operation is convenient and the structure is simple. Compared with the traditional detection method, which has many columns, complex structure, increased weight of the inspection fixture, and uses a segmented detection method, the middle segment cannot be inspected, and the operation is complicated, the present application has better application prospects.

[0031] It can be understood that the present invention is described by some embodiments, and those skilled in the art know that various changes or equivalent substitutions can be made to these features and embodiments without departing from the spirit and scope of the present invention. Although the embodiments of the present invention have been disclosed as above, they are not limited to the applications listed in the specification and the implementation mode. They can be fully applied to various fields suitable for the present invention. For those familiar with the art, other modifications can be easily realized. Therefore, without departing from the general concept defined by the claims and the equivalent scope, the present invention is not limited to specific details and the illustrations shown and described here.
