[0016] 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.

[0017] See also Figure 1-4 The utility model provides a technical solution: a special gauge capable of measuring height error, including a main body 1, such as Figure 1As shown, the main body 1 is a flat plate structure, and two dial gauges 2 are provided on the surface of the main body 1. The straight line of the dial gauge 2 extends along the length direction of the main body 1. The end surface of the main body 1 is movably provided with a positioning pin 3. The main body 1 is placed on the reference surface under the action of gravity and is positioned by the positioning pin 3. Then, the error value can be measured by the dial gauge 2. The measurement method and operation steps are public technology and will not be repeated here. Figure 2 As shown, one of the dial gauges 2 needs to be tilted at a certain angle, and the specific angle is determined by factors such as the specific size and requirements of the workpiece to be measured;

[0018] Specifically, the end faces of the main body 1 are respectively penetrated by a movable groove 4 and a rotating groove 5, the inner surface of the movable groove 4 is slidably provided with a movable block 6, and the inner surface of the rotating groove 5 is rotatably provided with a rotating block 7, the movable block 6 can slide along the length direction of the main body 1, and the rotation axis of the rotating block 7 is arranged in the same direction as the width direction of the main body 1, the end faces of the movable block 6 and the rotating block 7 are respectively penetrated by a connecting mechanism, and the dial gauge 2 is connected to the movable block 6 and the rotating block 7 respectively through the connecting mechanism, so that the spacing between the two dial gauges 2 is adjusted by controlling the movable block 6 to slide inside the movable groove 4, and the inclination angle of the dial gauge 2 can be adjusted by rotating the rotating block 7, as shown in FIG. Figure 1 As shown, in order to facilitate the movement of the gauge, a corresponding handle can be provided on the upper surface of the main body 1;

[0019] Specifically, the connecting mechanism includes a connecting sleeve 8 fixed on the movable block 6 or the rotating block 7. The diameter of the connecting sleeve 8 is slightly larger than the outer diameter of the scale of the micrometer 2 to facilitate the insertion of the micrometer 2. The interior of the connecting sleeve 8 is symmetrically provided with a clamping member 9 that is slidably connected to the connecting sleeve 8. The clamping member 9 is an arc-shaped plate and is centrally symmetrically arranged to increase the fitting area between the scale and maintain stable fixation of the micrometer 2. An elastic element is provided between the connecting sleeve 8 and the movable block 6 or the rotating block 7 to enable the connecting sleeve 8 to move in the opposite direction of the insertion direction of the micrometer 2. Specifically, a limit ring can be provided at the outer circumference of both ends of the connecting sleeve 8 to prevent the connecting sleeve 8 from detaching from the corresponding movable block 6 or the rotating block 7. The elastic element can be a spring and is sleeved on the outside of the connecting sleeve 8. Under the action of the elastic element, the connecting sleeve 8 is located at the upper end. The outer circumference of the clamping member 9 is provided with a movable rod 10 that moves along the radial direction of the connecting sleeve 8. The clamping member 9 is slidably connected to the side wall of the connecting sleeve 8 under the action of the movable rod 10, and the clamping member 9 can slide along the radial direction of the connecting sleeve 8 under the action of the movable rod 10. The inner wall of the movable block 6 or the rotating block 7 is provided with an inclined groove 11 that cooperates with the movable rod 10. Under the action of the elastic element and the action of the inclined groove 11, the movable rod 10 drives the clamping member 9 to have a tendency to approach each other, so that after the dial indicator 2 is inserted, the connecting sleeve 8 overcomes the sliding of the elastic element. Under the action of the inclined groove 11, the two clamping members 9 can move away from each other. After full insertion, under the action of the elastic element, the connecting sleeve 8 has a tendency to reset, and the clamping member 9 moves close to clamp the dial indicator 2 scale, fixes the dial indicator 2, and enables quick installation between the dial indicator 2 and the device.

[0020] Specifically, a slide groove 12 is provided on one side surface of the movable groove 4 extending in the same direction, and a slider 13 fixed to the movable block 6 is slidably provided on the inner surface of the slide groove 12. A screw rod 14 screwed to the slider 13 is rotatably provided in the slide groove 12, and the extension direction of the screw rod 14 extends in the same direction as the slide groove 12. A first knob for controlling the rotation of the screw rod 14 is provided on the outside of the main body 1. When the screw rod 14 rotates, the slider 13 slides inside the slide groove 12 under the action of the threaded fit to adjust the position of the movable block 6.

[0021] Specifically, the rotating block 7 is coaxially connected to the adjusting worm wheel 15, and the main body 1 is provided with an adjusting worm 16 meshing with the adjusting worm wheel 15. Figure 4 As shown, a cavity for accommodating an adjusting worm wheel 15 is provided inside the main body 1, and an adjusting worm 16 is extended along the length direction of the main body 1. By rotating the adjusting worm 16, the tilt angle of the rotating block 7 is adjusted;

[0022] When the utility model is used, the main body 1 is moved by the handle, and after the main body 1 is placed on the reference surface, the main body 1 is positioned by the positioning pin 3, and the measurement is performed by the micrometer 2. By rotating the screw rod 14, the slider 13 is controlled to slide inside the slide groove 12 under the action of the thread cooperation, and the movable block 6 is driven to slide along the movable groove 4 to adjust the distance between the two micrometers. By rotating the adjusting worm 16, the adjusting worm wheel 15 is driven to rotate, and the inclination angle of the rotating block 7 is adjusted. Therefore, the inspection tool can be flexibly adjusted according to factors such as the size requirements of the workpiece to be measured, and has a wider applicability.
