[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] like Figure 1As shown, a device for measuring the length and diameter of a bolt 4 includes a base plate 5, a door plate 22, a diameter measuring mechanism and a length measuring mechanism. The door plate 22 is mounted on the base plate 5, and a slide groove 8 is opened on both sides. The length measuring mechanism includes a top plate 12, a cylinder 14 and a first distance sensor 16. Slide blocks 19 are respectively provided at both ends of the top plate 12. The top plate 12 is vertically slidably connected to the slide groove 8 through the slide blocks 19. The cylinder 14 is arranged at the top center position of the door plate 22. The telescopic end of the cylinder 14 is connected to the frame plate 15. The frame plate 15 is fixedly connected to the upper surface of the top plate 12. The first distance sensor 16 is arranged at the top inside the slide groove 8 for monitoring the movable distance of the slider 19. The diameter measuring mechanism includes a motor 13, a pair of threaded rods 11, a pair of moving blocks 9, a pair of abutment plates 23, a pair of limit plates 7 and a second distance sensor 18. The motor 13 is fixedly arranged at the center position of the upper surface of the top plate 12. The motor 13 has two output ends and The cam 21 of the embodiment of the present invention is a kind of fixed plate 20 of the present invention, and the cam 21 of the embodiment of the present invention is a kind of fixed plate 20 of the present invention.

[0017] The detailed connection means are well known in the art. The following mainly introduces the working principle and process, which are as follows:

[0018] According to the instruction manual Figure 1It can be seen that when the present invention is used, the head of the bolt 4 is placed downward at the center position of the bottom plate 5, and the cylinder 14 works to drive the frame plate 15 and the top plate 12 to move downward. The sliders 19 on both sides of the top plate 12 are vertically slidably connected to the slide groove 8 of the door-shaped plate 22 to ensure the stability of the vertical movement and improve the measurement accuracy. The center position of the lower bottom surface of the top plate 12 abuts the top of the bolt 4. At this time, the first distance sensor 16 monitors the vertical movement distance of the slider 19 and feeds back to the external computer. At the same time, the motor 13 also works to drive the threaded rod 11 to rotate. Since the threaded rod 11 is screwed to the moving block 9 on the limit plate 7, and the limit plate 7 is horizontally slidably connected to the limit groove 20, the rotation of the threaded rod 11 drives the limit block to move horizontally. When measuring, it moves inward at the same time, thereby driving the fixed rod 21 and the abutment plate 23 to move inward and abut against the side surface of the bolt 4. At this time, the second distance sensor 18 monitors the horizontal movement distance of the limit plate 7 and feeds back to the external computer. The external computer can reversely calculate the length and direction of the screw through the initial value and the change value. The utility model can measure the diameter and length of the bolt 4 through the diameter measuring mechanism and the length measuring mechanism through one-time installation, which greatly improves the measurement efficiency and the convenience of measurement.

[0019] Among them, a mounting groove 2 is provided at the center position on the base plate 5, and the mounting seat 1 is seated in the mounting groove 2. The mounting groove 2 is provided with a contoured groove 3 that matches the head of the bolt 4. The mounting seat 1 can be disassembled and replaced. The contoured grooves 3 on different mounting seats 1 have different specifications, so that it is suitable for measuring more bolts 4 and has good stability during measurement.

[0020] Among them, a pressure sensor 6 is set at the center position of the bottom of the top plate 12, which is connected to the external control system for signal feedback of the cylinder 14 stopping and the motor 13 working, thereby improving the degree of automation.

[0021] Among them, a scale 17 is set at the position of the slide groove 8 on the outer wall of the door plate 22, which is used for manual observation and correction during maintenance as a reference.

[0022] Among them, a fixing plate 10 is provided on the upper outer surface of the top plate 12, and one end of the outer side of the threaded rod 11 is rotatably connected to the side surface of the fixing plate 10 to ensure the stability of the rotation of the threaded rod 11 and improve the measurement accuracy.

[0023] 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.
