DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments.

[0022] Referring to Figures 1-4 A gap adjusting device for precision medical instrument manufacturing, comprising an operating table 1, wherein the operating table 1 is provided with an adjusting assembly;

[0023] The adjusting assembly comprises a slide rail 2 fixedly connected with the operating table 1, symmetrically arranged adjusting plates 3 slidably connected with the slide rail 2, strip-shaped grooves 4 formed in the adjusting plates 3, adjusting blocks 5 slidably connected in the strip-shaped grooves 4, limiting grooves 6 formed in the two sides of the adjusting blocks 5, limiting rods 8 slidably connected with the adjusting blocks 5, pressing plates 7 fixedly connected with the upper ends of the limiting rods 8, transverse rods slidably connected with the adjusting blocks 5, threaded rods 9 fixedly connected with the sides of the adjusting plates 3 away from each other, threaded sleeves 10 arranged on the threaded rods 9, and drive assemblies arranged on the threaded sleeves 10.

[0024] In this design, the directions of the strip-shaped grooves 4 and the slide rail 2 are perpendicular to each other, and the adjusting blocks 5 are used according to the actual needs of the user to adjust the instruments to adapt to the tooling, when the user needs to adjust the internal gap of the precision medical instrument, first place the instrument on the adjusting plate 3, and according to the specific specifications and shapes of the instrument and whether the gap needs to be expanded or reduced, slide the adjusting block 5 to the inside or outside of the instrument, and rotate the pressing plate 7 to cover the instrument, and finally slide the transverse rod to press the pressing plate 7, so as to ensure that the pressing plate 7 cannot move up and down, which can fix the instrument.

[0025] Then the user rotates the threaded sleeve 10 through the drive assembly, uses the threaded sleeve 10 to cooperate with the two threaded rods 9, drives the two adjusting plates 3 to move towards each other or away from each other, at this time, after the tooling on the adjusting block 5 abuts against the instrument, it can drive the instrument to deform, thereby achieving the purpose of adjusting the gap of the instrument, at the same time, this design uses the threaded sleeve 10 to cooperate with the threaded rod 9 to drive, which is more stable in control when operating, and is not easy to cause excessive adjustment and subsequent repeated adjustment, improves the adjustment efficiency and stability, and also avoids damaging the instrument during adjustment.

[0026] Further, the driving assembly comprises a sleeve ring 11 rotationally connected with the threaded sleeve 10, a crank 12 fixedly connected with the sleeve ring 11, and a through hole formed in the sleeve ring 11, a sliding rod 13 inserted into the through hole, and a ratchet 14 rotationally connected with the sliding rod 13 through a spring shaft at both ends of the sliding rod 13, and two ratchets 15 fixedly connected with the side wall of the threaded sleeve 10 and matched with the ratchets 14, wherein the teeth of the two ratchets 15 are oppositely directed.

[0027] In this design, the sleeve ring 11 cooperates with the crank 12 to drive the sliding rod 13 to rotate along the axis of the threaded sleeve 10, and in the case that the ratchets 14 are arranged at both ends of the sliding rod 13, when the user needs to move the two adjusting plates 3 in the direction of moving away from or moving close to each other, the sliding rod 13 is slid to make one of the ratchets 14 engage with the ratchet 15, and then the user only needs to swing the crank 12 to drive the threaded sleeve 10 to rotate, which greatly facilitates the user to select the operation of the threaded sleeve 10, and saves time and effort.

[0028] Further, a plurality of stepped grooves are formed in the cross bar, and the cross bar is arranged to press the limiting rod 8.

[0029] In this design, the instrument has a plurality of different specifications, and therefore the stepped grooves are arranged to adapt to instruments of different thicknesses or outer diameters, so that after the cross bar presses the limiting rod 8, the lower surface of the limiting rod 8 is just in contact with the instrument, and the instrument will not be displaced during the gap adjustment operation, thereby improving the fixing effect on the instrument.

[0030] Further, a rubber sleeve 16 is arranged in the through hole, the length of the sliding rod 13 is less than the distance between the two ratchets 15, and a push block 17 is fixedly connected with the sliding rod 13 at both ends.

[0031] In this design, the rubber sleeve 16 is arranged to increase the friction between the sliding rod 13 and the through hole, so as to avoid displacement of the sliding rod 13 due to shaking of the crank 12 by the user during operation, and the push block 17 is arranged to facilitate the user to adjust the position of the sliding block and to avoid the situation that the fingers are stuck between the ratchet 15 and the ratchet 14 during adjustment.

[0032] Further, left-hand threads and right-hand threads are respectively formed in the threaded rods 9 arranged on the two adjusting plates 3, and the pitches of the left-hand threads and the right-hand threads are the same, and the internal threads of the threaded sleeve 10 are also respectively matched with the external threads of the two threaded rods 9, so that in the case of this design, when the threaded sleeve 10 rotates, the two adjusting plates 3 can be simultaneously moved in the direction of moving away from or moving close to each other.

[0033] Further, an indicating scale 18 is arranged on the sliding rail 2, and a pointer is fixedly connected with the adjusting plate 3 on the side close to the indicating scale 18.

[0034] In the design, the indication scale 18 cooperates with the pointer to facilitate the user to determine the adjustment distance, and it should be noted that the movement of the two adjustment plates 3 is synchronous, so the movement distance of the pointer on the indication scale 18 is half of the actual adjustment distance.

[0035] The above merely describes a preferred embodiment of the present application, but the protection scope of the present application is not limited to this. Any skilled person in the art, according to the technical scheme and the inventive concept of the present application, can make equivalent replacement or change within the technical range disclosed by the present application, which should be covered in the protection scope of the present application.
