DETAILED DESCRIPTION

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-5As shown, the utility model provides a technical solution: a fixing structure for micrometer testing, comprising a clamping mechanism 1, the clamping mechanism 1 comprising a fixing seat 101, and a mounting groove 102 is symmetrically arranged inside the fixing seat 101, a limited clamping rod 103 is slidably installed inside the mounting groove 102, and a clamping spring 104 is arranged on the surface of the limited clamping rod 103 located inside the mounting groove 102, because the clamping spring 104 is arranged, the limited clamping rod 103 is clamped inside the mounting groove 102 under the rebound action of the clamping spring 104, so that the clamping block 105 can be close to the fixing seat 101;

[0023] One end of the two sets of limit clamping rods 103 passes through the mounting groove 102 and is fixedly mounted with a clamping block 105, and one side of the top of the clamping block 105 is symmetrically fixedly mounted with a clamping column 106. Since the clamping block 105 is provided, the distance between the clamping block 105 and the fixing seat 101 is controlled by moving the clamping block 105, so that the micrometer body 5 of different specifications can be clamped and fixed on the clamping block 105 and the top of the fixing seat 101;

[0024] An adjusting screw 2 is fixedly installed at the bottom of one side of the fixing seat 101 close to the clamping block 105, and one end of the adjusting screw 2 passes through the clamping block 105 and is fixedly installed with an end plate 201, and an adjusting screw sleeve 202 is provided on the surface of the adjusting screw 2 located on one side of the clamping block 105. Since the adjusting screw sleeve 202 is provided, the adjusting screw sleeve 202 is turned to control the maximum distance between the clamping block 105 and the fixing seat 101, ensuring that when the micrometer body 5 is clamped and fixed, the clamping block 105 will not arbitrarily move away from the fixing seat 101, causing the micrometer body 5 to fall off;

[0025] A mounting block 3 is fixedly installed on one side of the top of the clamping mechanism 1 away from the adjusting screw 2, and a second clamping column 301 is symmetrically fixedly installed on one side of the mounting block 3. A rectangular groove 302 is provided on the side of the mounting block 3 away from the second clamping column 301, and a second mounting groove 303 is symmetrically provided on one side of the inner wall of the rectangular groove 302, and a first slide groove 304 is provided at one end of the second mounting groove 303 away from the rectangular groove 302, and a limiting slide bar 305 is slidably installed inside the second mounting groove 303, and the limiting slide bar 305 penetrates the second mounting groove 303 and extends to the inside of the rectangular groove 302 and the first slide groove 304. By providing the limiting slide bar 305, the limiting slide bar 305 is controlled to slide inside the second mounting groove 303, so that the clamping strip 309 is retracted into or extended out of the rectangular groove 302, thereby controlling the clamping strip 309 to clamp or loosen the slide plate 402.

[0026] A clamping spring 306 is provided on the surface of the limiting slide bar 305 located inside the second installation groove 303. Due to the clamping spring 306, the limiting slide bar 305 is pushed toward the rectangular groove 302 under the elastic action of the clamping spring 306, so that the clamping strip 309 can always be clamped on the surface of the clamping rack 404, and the slide plate 402 is clamped and fixed;

[0027] A lever 307 is fixedly installed at one end of the limiting slide bar 305 located inside the slide slot 1 304, and two groups of levers 307 pass through the slide slot 1 304 and are fixedly installed with a connecting plate 308. A clamping strip 309 is fixedly installed at one end of the two groups of limiting slide bars 305 located inside the rectangular groove 302. Because of the connecting plate 308, the connecting plate 308 is pushed to control the synchronous movement of the two groups of limiting slide bars 305, so that the clamping strip 309 can move smoothly inside the rectangular groove 302 without tilting.

[0028] A concave seat 4 is fixedly installed on one side of the clamping mechanism 1 away from the adjusting screw 2, and two slide grooves 401 are symmetrically provided on both sides of the concave seat 4. A slide plate 402 is slidably installed inside the concave seat 4, and sliding protrusions 403 are fixedly installed on the bottom of both sides of the slide plate 402, and the sliding protrusions 403 pass through the two slide grooves 401. Because the two slide grooves 401 and the sliding protrusions 403 are provided, when the slide plate 402 slides inside the concave seat 4, the sliding protrusions 403 slide inside the two slide grooves 401, ensuring that the slide plate 402 will not separate from the concave seat 4.

[0029] A clamping rack 404 is provided on one side of the slide plate 402, and the clamping rack 404 corresponds to the clamping strip 309. By providing the clamping rack 404 and the clamping strip 309, the clamping strip 309 is clamped into the clamping rack 404 at different positions to control the different sliding heights of the slide plate 402 inside the concave seat 4;

[0030] A top seat 405 is fixedly installed on the top of the clamping rack 404. Since the top seat 405 is provided, after the top seat 405 is lifted to be in close contact with the micrometer body 5, the micrometer body 5 is supported to prevent the micrometer body 5 from tipping over.

[0031] A micrometer body 5 is provided between the top of the clamping mechanism 1 and the mounting block 3. The bottom of the micrometer body 5 is symmetrically provided with fixing holes 501, and the fixing holes 501 correspond to the clamping column 1 106 and the clamping column 2 301. Because the fixing holes 501 are provided, after the clamping column 1 106 and the clamping column 2 301 are inserted into the corresponding fixing holes 501, the micrometer body 5 is clamped and fixed.

[0032] The working principle of the utility model is:

[0033] The adjusting screw sleeve 202 is twisted away from the clamping block 105, and the clamping block 105 is pulled to move the clamping column 106 and the clamping column 2 301 away from each other, and the micrometer body 5 is placed between the clamping column 106 and the clamping column 2 301 accordingly. The clamping block 105 is loosened, and under the rebound effect of the compression spring 104, the clamping block 105 is pressed toward the fixing seat 101, so that the clamping column 106 and the clamping column 2 301 are clamped into the corresponding fixing hole 501. The adjusting screw sleeve 202 is tightened to clamp the clamping block 105 on the surface of the micrometer body 5, and the slide plate 402 is pushed upward until the top seat 405 is close to the surface of the micrometer body 5. Under the meshing and clamping effect of the clamping strip 309 and the clamping rack 404, the slide plate 402 is clamped and fixed inside the concave seat 4.

[0034] When disassembling the micrometer body 5, screw the adjusting screw sleeve 202 away from the clamping block 105, and pull the clamping block 105 at the same time to make the clamping column 106 disengage from the fixing hole 501, loosen and remove the micrometer body 5 from between the clamping column 106 and the clamping column 2 301, push the connecting plate 308 to drive the limiting slide bar 305 to slide inside the installation groove 2 303, control the clamping strip 309 to retract into the rectangular groove 302 away from the clamping rack 404, so that the slide plate 402 can slide down inside the concave seat 4.

[0035] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0036] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
