[0002] A gauge block is a length standard measuring tool, usually made of materials with high hardness and high precision, having very accurate length dimensions. The main function of a gauge block clamp is to firmly hold the gauge block so as to conveniently operate the gauge block during measurement, calibration and other work, and at the same time ensure that the gauge block will not move, slip, etc. during use, ensuring the accuracy and stability of measurement.
[0003] When calibrating the inner diameter and outer circle of large sizes, a gauge block clamp is often used. During the actual use of the existing gauge block clamps, although the function of basically clamping and fixing the gauge block can be realized, generally the existing gauge block clamps do not have the function of adjusting the length. If the length of the gauge block is greater than that of the gauge block clamp, at this time, the existing gauge block clamp will not be able to clamp and fix the gauge block, and a suitable gauge block clamp needs to be replaced to hold the gauge block, so that the use of the gauge block clamp has limitations, and therefore it needs to be improved.

Specific embodiments
[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0023] As Figures 1 to 5 shown, the present utility model provides a gauge block clamp capable of calibrating the inner diameter and outer circle of large sizes, including a gauge block clamp 1. The right side of the gauge block clamp 1 is movably connected with a rectangular block 2. The left side of the rectangular block 2 is fixedly connected with a connecting plate 3. The left side of the connecting plate 3 penetrates through the gauge block clamp 1 and extends to the inside of the gauge block clamp 1 and is movably connected with the inner surface of the gauge block clamp 1. The inside of the gauge block clamp 1 is movably sleeved with a movable shaft 4 located below the connecting plate 3. The right side of the movable shaft 4 penetrates through the gauge block clamp 1 and extends to the inside of the gauge block clamp 1 and is fixedly sleeved with a gear 5. The outer surface of the gear 5 is movably connected with the inner surface of the gauge block clamp 1. The outer surface of the gear 5 is meshed with a toothed plate 6. The top of the toothed plate 6 is fixedly connected with the bottom of the connecting plate 3. The top of the movable shaft 4 is fixedly connected with a turning handle 7.
[0024] Rotating the turning handle 7 will cause the movable shaft 4 to drive the gear 5 to rotate, and then cause the gear 5 to mesh with the toothed plate 6 and drive the entire connecting plate 3 to move to the right, thereby achieving the purpose of adjusting the length of the gauge block clamp 1.
[0025] Among them, the inside of the rectangular block 2 is threadedly connected with a threaded rod 8. The other end of the threaded rod 8 is movably sleeved with a movable clamping block 9. The outer surface of the movable clamping block 9 is movably connected with the inner surface of the gauge block clamp 1. The left side of the bottom of the inner cavity of the gauge block clamp 1 is fixedly connected with a fixed clamping block 10.
[0026] Rotating the threaded rod 8 to move leftward will drive the movable clamping block 9 to move leftward. With the cooperation of the movable clamping block 9 and the fixed clamping block 10, the gauge block is clamped and fixed, thus facilitating the calibration of the inner diameter and outer circle of large sizes.
[0027] Wherein, anti-slip sheets 11 are movably sleeved inside both the movable clamping block 9 and the fixed clamping block 10. The number of the anti-slip sheets 11 is two, and the outer surfaces of the two anti-slip sheets 11 are movably connected to the inner surface of the gauge block clamp 1.
[0028] The design of the anti-slip sheets 11 serves to prevent the gauge block from sliding.
[0029] Wherein, side cavities 12 are opened at the tops of both the movable clamping block 9 and the fixed clamping block 10. Springs 13 are fixedly connected inside the side cavities 12. The other ends of the springs 13 are fixedly connected to movable blocks 14. The number of the movable blocks 14 is two, and the outer surfaces of the two movable blocks 14 are movably connected to the inner surfaces of the side cavities 12.
[0030] When the two movable blocks 14 move away from each other to release the fixing effect on the anti-slip sheets 11, pulling the anti-slip sheets 11 upward at this time can achieve the purpose of quickly replacing the anti-slip sheets 11.
[0031] Wherein, pull rods 15 are fixedly connected to the tops of the two movable blocks 14, and the appearance of the pull rods 15 is rectangular.
[0032] The design of the pull rods 15 facilitates the operator to drive the movement of the movable blocks 14 by pulling the pull rods 15.
[0033] Wherein, limiting grooves 16 are opened at the bottoms of the inner cavities of both the gauge block clamp 1 and the connecting plate 3. Limiting blocks 17 are movably connected to the inner surfaces of the limiting grooves 16, and the tops of the limiting blocks 17 are fixedly connected to the bottoms of the movable clamping block 9.
[0034] The design of the limiting grooves 16 and the limiting blocks 17 serves to limit the movement of the movable clamping block 9.
[0035] Wherein, the number of the springs 13 is two, and the two springs 13 have the same size.
[0036] The design of the two springs 13 has a better reset effect on the two movable blocks 14.
[0037] Wherein, the outer surface of the limiting block 17 is smooth, and the width of the limiting block 17 is the same as the width of the limiting groove 16.
[0038] Such a design enables the limiting block 17 to slide better inside the limiting groove 16.
[0039] The working principle and usage process of the present utility model:
[0040] When the gauge block clamp 1 is not applicable to large-sized gauge blocks, rotating the turning handle 7 at this time will cause the movable shaft 4 to drive the gear 5 to rotate, and then the gear 5 will mesh with the toothed plate 6 and drive the connecting plate 3 to move to the right as a whole, thus achieving the purpose of adjusting the length of the gauge block clamp 1 and improving the applicable range of the gauge block clamp 1.
[0041] Since the anti-slip pieces 11 hold the gauge block for a long time, the anti-slip pieces 11 are severely worn and need to be replaced. At this time, pulling the two pull rods 15 to move away from each other will drive the two movable blocks 14 to move away from each other and compress the two springs 13. When the two movable blocks 14 move to the outside of the two anti-slip pieces 11, the fixing effect on the two anti-slip pieces 11 will be released. At this time, pulling the two anti-slip pieces 11 upward can quickly disassemble the anti-slip pieces 11, thus achieving the purpose of facilitating the replacement of the anti-slip pieces 11.
