[0025] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Reference Figure 1-6 , which is the first embodiment of the utility model, provides a gauge for a star-shaped sleeve, the gauge for the star-shaped sleeve comprises a workbench 1, a star-shaped sleeve 2 mounted on the surface of the workbench 1, and a test piece 3 is mounted on the surface of the workbench 1;

[0027] The test piece 3 includes a rotating plate 31 movably mounted on the surface of the workbench 1. A ring-shaped array of driving grooves 32 are provided inside the rotating plate 31. The driving grooves 32 are arranged in an arc shape. A positioning rod 33 is movably connected inside the driving groove 32. A rubber ball 34 is installed on one side of the positioning rod 33. The rubber ball 34 is located on the side of the star-shaped sleeve 2. The rubber ball 34 is located in the groove on the outer surface of the star-shaped sleeve 2, which can be conveniently clamped and positioned. At the same time, the concentricity of the star-shaped sleeve 2 is judged to be consistent according to the degree of connection between the six groups of rubber balls 34 and the grooves.

[0028] The outer surface of the rotating plate 31 is fixedly connected to a ring-shaped array of teeth 311, and the surface of the workbench 1 and one side of the teeth 311 are rotatably connected to a gear 312, the gear 312 and the teeth 311 are meshed with each other, and the top of the gear 312 is fixedly connected to a knob 313, and the outer surface of the knob 313 is fixedly connected to a ring-shaped array of rubber blocks, which can facilitate the rotation of the staff. At the same time, the setting of the knob 313 can conveniently drive the rotating plate 31 to rotate, so as to drive the positioning rods 33 to approach each other.

[0029] The surface of the positioning rod 33 is fixedly connected to a limiting ring 36. The limiting ring 36 is provided with two groups, which are respectively located at the top and the bottom of the rotating plate 31. The bottom of the positioning rod 33 is fixedly connected to a slider 37. The slider 37 is located inside the rotating plate 31 and is movably connected to it. The setting of the limiting ring 36 can position the positioning rod 33 on the surface of the rotating plate 31 and prevent it from being offset. The setting of the slider 37 can make the movement of the positioning rod 33 more stable.

[0030] Both sides of the slider 37 are fixedly connected to the limit strips 371, the interior of the workbench 1 is provided with a circular array of slide grooves 372, the inner side of the slide grooves 372 is provided with a limit slot 373, the slider 37 is located inside the slide grooves 372 and is movably connected thereto, the limit strips 371 are located inside the limit slots 373 and are movably connected thereto, thus ensuring the stability of the positioning rod 33 when it moves.

[0031] A placing plate 4 is provided on the top of the rotating plate 31, and a circular array of cavities 41 is opened inside the placing plate 4. The cavity 41 is located at the top of the driving groove 32. The surface of the placing plate 4 is fixedly connected with a circular array of legs 42, and the bottom of the legs 42 is fixedly connected to the workbench 1. The positioning rod 33 is located inside the cavity 41, and the star-shaped sleeve 2 is located on the surface of the placing plate 4 and is movably connected thereto. The positioning rod 33 is located inside the cavity 41 and passes through the cavity 41, which can facilitate the movement of the positioning rod 33 and prevent the placing plate 4 from interfering with its movement. In addition, it can prevent the star-shaped sleeve 2 from rotating with the rotation of the rotating plate 31.

[0032] A cover plate 5 is installed on the top of the star-shaped sleeve 2. A circular array of movable grooves 52 are provided inside the cover plate 5. The movable grooves 52 are located at the top of the driving grooves 32. Scales 51 are provided on the surface of the cover plate 5 and on both sides of the movable grooves 52. The movable grooves 52 are arranged in a straight line to facilitate the movement of the positioning rod 33.

[0033] The positioning rod 33 extends to the top of the cover plate 5 through the movable groove 52. Arrows 35 are provided on both sides of the top of the positioning rod 33. The positioning rod 33 is located inside the movable groove 52 and is movably connected thereto, so that the staff can observe the position of each set of scales 51 conveniently, so as to quickly observe whether the concentricity of the star sleeve 2 meets the standard.

[0034] The surface of the workbench 1 is fixedly connected with a positioning shaft 314, and the rotating plate 31, the placement plate 4, and the cover plate 5 are all sleeved on the surface of the positioning shaft 314 and movably connected thereto, which can facilitate the normal operation of the positioning rod 33 and avoid interference therewith.

[0035] During use, the star sleeve 2 is sleeved on the surface of the positioning shaft 314 so that the bottom of the star sleeve 2 is located on the top of the placement plate 4, and then the cover plate 5 is sleeved on the top of the positioning shaft 314 so that the bottom is located on the top of the star sleeve 2, and then the knob 313 is rotated to drive the gear 312 to rotate, and the rotating plate 31 is driven to rotate through the teeth 311, so that the rotating plate 31 drives the driving slot 32 to rotate;

[0036] At the same time, due to the rotation of the driving slot 32, the positioning rod 33 inside it will slowly move toward the positioning axis 314 as the driving slot 32 rotates. When the positioning rod 33 moves, it will move along the sliding slot 372 and the inside of the limiting slot 373 through the slider 37 at the bottom and the limiting strips 371 on both sides thereof, so as to ensure the stability of the positioning rod 33 when moving.

[0037] At the same time, the top of the positioning rod 33 will move through the cavity 41 along the inside of the moving groove 52 toward the outer surface of the star sleeve 2 until the rubber ball 34 inside the positioning rod 33 is completely in contact with the groove on the outer surface of the star sleeve 2. At this time, the specific position of the scale 51 pointed by the arrow 35 on the outer side of the top of the positioning rod 33 can be observed, and at the same time, it can be observed whether the star sleeve 2 is completely clamped by the rubber ball 34. If one or more groups of rubber balls 34 are completely fitted with their grooves, it is unqualified. At the same time, by squeezing the star sleeve 2, if it shakes slightly, it is unqualified. Otherwise, the concentricity is qualified.

[0038] In this way, the concentricity detection of the star sleeve 2 can be completed. At the same time, by rotating the knob 313, the rotating plate 31 drives the multiple groups of positioning rods 33 to move synchronously toward the star sleeve 2, so that the detection operation can be completed in one go, avoiding the phenomenon of rotating and adjusting the star sleeve 2, thereby saving time.

[0039] Moreover, the method of sleeve-arranging the cover plate 5 on the surface of the positioning shaft 314 removes some restrictions, and can facilitate the detection of star-shaped sleeves 2 at different heights. In addition, this method is simple to operate and easy to use, and has relatively low experience requirements.

[0040] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
