DETAILED DESCRIPTION

[0021] 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 described embodiments 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 creative work are within the scope of protection of the present invention.

[0022] See also Figure 1-5In this embodiment, a portable spacing measuring device for testing the displacement accuracy of a converter slide comprises a slide seat 1 and a ruler 2. The slide 108 inside the slide seat 1 can be used to cooperate with the fixed plate 106 to realize the opening and closing of the feed port by sliding. The ruler 2 is arranged on the top of the slide seat 1. The ruler 2 can be assembled on the slide seat 1 to measure the accuracy of the slide 108 on the slide seat 1, predict the displacement size in advance, and take preventive measures. The ruler 2 comprises a support bar 3 as a supporting frame of the ruler 2, which is used to connect the entire ruler 2. A ruler tape 4 is attached to the front side of the support bar 3. The ruler tape 4 is divided into left and right scale marks, which is convenient for observing and understanding the installation of the slide 108 Whether there is a positive or negative deviation, a protective cover 5 is fixed on the front side of the support bar 3 to protect the front side of the ruler tape 4 to prevent the ruler tape 4 from being damaged. Connecting blocks 6 are fixed on both sides of the bottom of the support bar 3. Slide bars 7 are fixed at the bottom of the two connecting blocks 6. The connecting blocks 6 are used to assemble the slide bars 7 to fix the position of the slide bars 7. The outer sliding connection of the slide bar 7 is connected to a slide frame 8, which can slide on the slide bar 7 to cooperate with the displacement action of the slide plate 108. The front side of the slide frame 8 is threadedly connected with a centering screw 9, which is convenient for locking the slide frame 8 before measurement to achieve position calibration. The internal rotation of the slide frame 8 is connected with a rotating shaft 10, which is one of the main structures of the fixed foundation and can improve the rotation To transmit power, a rotating wheel 11 is fixed to the outside of the rotating shaft 10, which is convenient for the hand to hold the rotating shaft 10 to rotate. A pointer 12 is fixed to the top of the rotating shaft 10. The rotating shaft 10 located inside the sliding frame 8 is calibrated by the sliding frame 8 to ensure that the rotating shaft 10 and the pointer 12 are centered. The top of the pointer 12 extends to the inside of the protective cover 5, corresponding to the center of the ruler 4, which is convenient for observing the displacement of the slide 108 on the slide seat 1. A supporting frame 13 is fixed to the bottom of the sliding frame 8, and its bottom can bear the top of the sliding nozzle pipe 109 to ensure the position after installation. A mounting tube 14 is fixed to the inside of the supporting frame 13, which can be plugged into the sliding nozzle pipe 109. The slide plate 108 at the bottom of the nozzle tube 109 is slidable, and is used to drive the sliding nozzle tube 109 and the loading barrel 14 to move to achieve position change. A fastening mechanism 15 is fixed to the outside of the rotating shaft 10, which can be fastened to the inner wall of the sliding nozzle tube 109 and fixed after installation. Vertical bars 16 located on the side where the two connecting blocks 6 are separated are fixed on both sides of the bottom of the support bar 3. A threaded block 17 is fixed on the side of the vertical bar 16 away from the slide seat 1. The internal thread of the threaded block 17 is connected to a screw 18. A fastening plate 19 is fixed to the side of the screw 18 close to the slide seat 1. The threaded feed of the screw 18 can clamp the fastening plate 19 on the outside of the mounting seat 102 of the slide seat 1.

[0023] The fastening mechanism 15 in this embodiment includes a two-way cam 151. The two-way cam 151 is fixed to the outside of the rotating shaft 10. The two-way protrusion design can simultaneously have a two-way hinged basis, which is convenient for realizing motion transmission on both sides. The front and rear sides of the two-way cam 151 are hinged with connecting rods 152. The hinged connection relationship can ensure that there is no jamming during the motion transmission process. The side of the connecting rod 152 away from the two-way cam 151 is hinged with a fastening block 153, wherein the fastening block 153 is slidably connected to the mounting tube 14. The sliding design of the fastening block 153 can utilize the motion transmission of the connecting rod 152 to slide inside the mounting tube 14, so as to extend to the outside of the mounting tube 14 and fit on the inner wall of the sliding nozzle tube 109.

[0024] The working principle of the above embodiment is:

[0025] (1) When in use, the installation tube 14 is inserted into the sliding nozzle tube 109, and the ruler 2 is lifted by using the supporting frame 13 and the supporting foundation at the top of the sliding nozzle tube 109. The rotating wheel 11 is rotated so that it is driven by force to drive the rotating shaft 10 to move synchronously. While the rotating shaft 10 rotates inside the sliding frame 8, its bottom drives the two-way cam 151 to rotate. The two-way cam 151 links the connecting rod 152 and acts on the fastening block 153. The fastening block 153 slides along the guide plate and extends to the outside of the installation tube 14 until it fits on the inner wall of the sliding nozzle tube 109. At this time, the rotating shaft 10 is locked by rotating the locking screw, so that the fastening mechanism 15 connected to the rotating shaft 10 will not loosen or reset.

[0026] (2) After fixing the mounting tube 14, push the slide bar 7 to make it slide inside the slide frame 8 until the center of the scale tape 4 corresponds to the top of the pointer 12, and rotate the centering screw 9 to lock the slide bar 7 and the slide frame 8 to ensure the calibration of the pointer 12 and the scale tape 4. In addition, rotate the screws 18 on the two vertical bars 16 respectively to make the screws 18 feed along the threaded block 17 until the fastening plate 19 is pushed to fit the outer side of the mounting seat 102. Finally, through the action of the moving plate 107, the slide plate 108 and the sliding nozzle pipe 109 are pushed to move. After the movement, the sliding nozzle pipe 109 drives the mounting tube 14 and the pointer 12 to move. By observing the displacement of the pointer 12, it is convenient to understand the displacement distance of the slide plate 108 and realize the displacement size measurement of the slide plate 108.
