[0021] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described below in conjunction with the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.

[0023] See also Figure 1 - Figure 3 The utility model provides a technical solution: a tool for quickly detecting the outer diameter of a part, comprising a device body 1, four device blocks 2 are installed on the top of the device body 1, and the four device blocks 2 are symmetrically distributed on the top of the device body 1 in pairs, wherein a detection stop 7 is arranged between two of the device blocks 2, and a detection through-port 8 is arranged between the other two device blocks 2, wherein stop adjustment grooves 3 are opened on the tops of two of the device blocks 2, and through-port adjustment grooves 4 are opened on the tops of the other two device blocks 2, two stop adjustment screws 5 are symmetrically installed inside the stop adjustment groove 3, and two through-port adjustment screws 6 are symmetrically installed on the inner side of the through-port adjustment groove 4, four threaded grooves 12 are opened on the surface of the device body 1, and the bottom ends of the stop adjustment screws 5 and the through-port adjustment screws 6 are threadedly connected to the threaded grooves 12, and two movable mechanisms 9 are installed in the inner cavity of the device body 1.

[0024] When conducting the inspection, it is first necessary to control the size of the inspection stop 7 and the inspection port 8. The inspection port 8 is set as the upper limit of the allowable deviation of the measured outer diameter, and the inspection stop 7 is set as the lower limit of the allowable deviation of the measured outer diameter. First, place the part at the inspection port 8 and move it. If the part can pass through the inspection port 8 smoothly, it means that its outer diameter is smaller than the size set for the inspection port 8. Then, continue to move the part to determine whether it can pass through the inspection stop 7. If the part can pass through the inspection stop 7, it means that its outer diameter is smaller than the size set for the inspection stop 7, and therefore does not meet the standard. On the contrary, if the part cannot pass through the inspection stop 7, it means that its outer diameter is between the inspection stop 7 and the inspection port 8, and meets the standard.

[0025] According to the inspection requirements of different parts, the size of the inspection stop 7 and the inspection through-port 8 can be adjusted. The stop adjustment screw 5 and the through-port adjustment screw 6 are turned so that they no longer squeeze the device block 2, so that the device block 2 can move freely. Since the bottom ends of the stop adjustment screw 5 and the through-port adjustment screw 6 are thinner, they cooperate with the stop adjustment groove 3 and the through-port adjustment groove 4 to allow the device block 2 to have a certain amount of movement space. In this way, when inspecting different parts, the size of the inspection stop 7 and the inspection through-port 8 can be adjusted as needed.

[0026] Finally, when testing a large number of parts, it is only necessary to put the parts into the testing device one by one, and determine whether they meet the standards by observing whether they can pass through the testing stop 7 and the testing opening 8. This method simplifies the testing process and improves the testing efficiency.

[0027] like Figure 4 As shown, the movable mechanism 9 includes a fixed rod 91 and a linkage rod 93, both ends of the fixed rod 91 are fixedly connected to the inner wall of the device body 1, and both ends of the fixed rod 91 are slidably connected to the outer surface with sliding sleeves 92, and both ends of the linkage rod 93 are fixedly connected to movable parts 97. When one device block 2 is moved, another device block 2 can be moved synchronously.

[0028] like Figure 4 As shown, one of the movable parts 97 is rotationally connected to the sliding sleeve 92, and the other movable part 97 is rotationally connected to the connecting block 96, so that the movable part 97 can be used to make the sliding sleeve 92 and the connecting block 96 move synchronously.

[0029] like Figure 4 As shown, a moving plate 94 is fixedly connected to the top of the connecting block 96 , and two moving rods 941 are symmetrically fixedly connected to the top of the moving plate 94 . When the moving plate 94 moves, the position of the device block 2 can be controlled by the moving rods 941 .

[0030] like Figure 4As shown, two slide bars 95 are slidably connected to the inner side of the moving plate 94, and one end of the slide bar 95 is fixedly connected to the inner wall of the device body 1, so as to limit the moving track of the moving plate 94 so that it remains straight when moving.

[0031] like Figure 4 As shown, a guide hole 11 is opened on the surface of the device body 1, and the top end of the moving rod 941 is slidably connected to the guide hole 11. The moving rod 941 is limited by the guide hole 11 to ensure that the moving rod 941 will not be skewed when driving the device block 2 to move.

[0032] like Figure 4 As shown, the top of the moving rod 941 is fixedly connected to the bottom of the device block 2, and can drive the device block 2 to slide.

[0033] The method of using this device and its working principle: When inspecting parts, you must first control the size of the inspection stop 7 and the inspection port 8. The inspection port 8 is set as the upper limit of the allowable deviation of the outer diameter, and the inspection stop 7 is set as the lower limit of the allowable deviation of the outer diameter. First, place the part at the inspection port 8 and move it. If the part can pass through the inspection port 8 smoothly, it means that its outer diameter is smaller than the size set for the inspection port 8. Then, continue to move the part to determine whether it can pass through the inspection stop 7. If the part can pass through the inspection stop 7, it means that its outer diameter is smaller than the size set for the inspection stop 7, and therefore does not meet the standard. On the contrary, if the part cannot pass through the inspection stop 7, it means that its outer diameter is between the inspection stop 7 and the inspection port 8, and meets the standard.

[0034] According to the inspection requirements of different parts, the size of the inspection stop 7 and the inspection through-port 8 can be adjusted. The stop adjustment screw 5 and the through-port adjustment screw 6 are turned so that they no longer squeeze the device block 2, so that the device block 2 can move freely. Since the bottom ends of the stop adjustment screw 5 and the through-port adjustment screw 6 are thinner, they cooperate with the stop adjustment groove 3 and the through-port adjustment groove 4 to allow the device block 2 to have a certain amount of movement space. In this way, when inspecting different parts, the size of the inspection stop 7 and the inspection through-port 8 can be adjusted as needed.

[0035] When the movable device block 2 moves, only one device block 2 needs to be moved to make the bottom movable rod 941 slide. This causes the movable rod 941 to slide inside the guide hole 11, and at the same time drives the movable plate 94 to slide on the surface of the slide rod 95. As the movable plate 94 slides, the bottom connecting block 96 also moves. The movable parts 97 at both ends of the connecting block 96 can drive the linkage rod 93 to move together, thereby controlling the sliding of the two sliding sleeves 92 on the surface of the fixed rod 91.

[0036] Then, when the two sliding sleeves 92 on the surface of the fixed rod 91 begin to slide, they will approach or move away from each other according to the moving direction of the previously active device block 2. Since the two sliding sleeves 92 are connected to another connecting block 96 through the linkage rod 93 and the movable member 97, the two connecting blocks 96 will slide synchronously. Through the coordinated action of the moving plate 94 and the moving rod 941, the other device block 2 will also begin to slide.

[0037] Therefore, when adjusting the two device blocks 2 to control the detection size of the detection stop 7 or the detection opening 8, the two device blocks 2 will move synchronously to ensure that the central axis of the detection stop 7 and the detection opening 8 are always located on the same straight line. This not only ensures the accuracy of the size adjustment, but also ensures that when the parts are inspected, they can be quickly inspected through the detection stop 7 and the detection opening 8.

[0038] The above description is only a preferred embodiment of the present invention and does not limit the present invention in other forms. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes and apply it to other fields. However, any simple modification, equivalent change and modification made to the above embodiment based on the technical essence of the present invention without departing from the content of the technical solution of the present invention still falls within the protection scope of the technical solution of the present invention.
