Technical Field
[0001] The utility model belongs to the technical field of machining, and particularly relates to a special measuring tool for a V-groove hoop. Background Art
[0002] A hoop is a component that holds or clamps another material, belonging to fasteners. It is formed by the butting connection of two semi-sheet-like hoops. Both semi-sheet-like hoops are in a semi-circular ring shape, and connecting ears are integrally formed at both ends of the semi-circular ring. The connecting ears are used to connect the two semi-sheet-like hoops to each other through bolts and other connecting pieces to achieve the fastening effect.
[0003] There is a kind of hoop structure that adopts the structure of a V-groove and a hoop band. Its structure is that a connecting piece is arranged at the connection of the hoop band, and a V-shaped card slot is arranged on the inner wall of the hoop band. During the production process of the hoop, it is necessary to detect the dimensions, and it is difficult to measure the bottom spacing of the V-groove hoop. Summary of the Utility Model
[0004] In order to solve the above technical problems, the utility model provides a special measuring tool for a V-groove hoop.
[0005] In order to achieve the purpose of the utility model, the technical scheme adopted by the utility model is as follows:
[0006] A special measuring tool for a V-groove hoop includes a hand-held pliers and a torsion spring. An arc-shaped measuring scale is fixedly connected to the end of one handle of the hand-held pliers, and an axial sliding groove is arranged at the end of the other handle. The measuring scale passes through the sliding groove so that this handle can slide along the measuring scale. Blocks are arranged at the ends of a pair of jaws of the hand-held pliers. The opposite surfaces of the two blocks are spherical and face the outside of the pair of jaws; the two ends of the torsion spring are respectively arranged on the pair of handles.
[0007] An alignment line corresponding to the measuring scale is arranged on the outer wall of the sliding groove of the utility model.
[0008] The handle and the jaw of the utility model are integrally formed.
[0009] The hand-held ends of the pair of handles of the utility model are close to each other.
[0010] Preferably, when the torsion spring is in a natural state, the hand-held ends of the pair of handles are parallel.
[0011] A stop block is arranged at one end of the measuring scale outside the sliding groove of the utility model.
[0012] The beneficial effects of the present utility model are as follows: Two outwardly extending clamping blocks are provided at a pair of clamping heads of the hand-held pliers. During measurement, the spherical surfaces of the two clamping blocks are respectively clamped on the opposite inner sides of the V-shaped groove. One of the handles slides along the measuring scale, and a measured value is obtained through the measuring scale and recorded as a reference value for measuring the size of the V-shaped groove hoop workpiece. The measurement is fast and the use is convenient. Description of the Drawings

[0016] In order to more clearly and detailedly illustrate the technical solution of the purpose of the present utility model, the present utility model will be further described below through relevant embodiments. The following embodiments are only for specifically illustrating the implementation method of the present utility model and do not limit the protection scope of the present utility model.
[0017] Embodiment 1
[0018] As Figure 1 shown, a special measuring tool for a V-shaped groove hoop includes a hand-held pliers and a torsion spring 5. An arc-shaped measuring scale 3 is fixedly connected to the end of one handle of the hand-held pliers, and an axial slide groove 11 is provided at the end of the other handle. The measuring scale 3 passes through the slide groove 11 so that this handle can slide along the measuring scale 3. Clamping blocks 4 are provided at the ends of a pair of clamping heads 2 of the hand-held pliers. The opposite surfaces of the two clamping blocks 4 are spherical surfaces and face the outside of the pair of clamping heads 2; both ends of the torsion spring 5 are respectively arranged on the pair of handles 1.
[0019] As Figure 2 shown, first, a standard part of the V-shaped groove hoop is taken for calibration. The pair of clamping heads 2 are directed towards the hoop, the two handles 1 are tightened inward, the two clamping blocks 4 are placed inside the hoop, and the handles 1 are released. Under the action of the torsion spring 5, the two clamping heads 2 open, and the spherical surfaces of the two clamping blocks 4 are respectively clamped on the opposite inner sides of the V-shaped groove 81. One of the handles 1 slides along the measuring scale 3, and a measured value is obtained through the measuring scale 3. Record it as a reference value for measuring the size of the V-shaped groove hoop workpiece. Whenever the error between the measured value and the reference value exceeds the threshold, it is unqualified.
[0020] Embodiment 2
[0021] Based on Embodiment 1 of the present utility model:
[0022] The handle 1 and the jaw 2 are integrally formed.
[0023] The hand-held ends of a pair of the handles 1 approach each other, and the measuring range is larger by the lever principle.
[0024] Embodiment 3
[0025] Based on Embodiment 1 of the present utility model:
[0026] When the torsion spring 5 is in a natural state, the hand-held ends of a pair of the handles 1 are parallel.
[0027] An alignment line 6 corresponding to the measuring scale 3 is provided on the outer wall of the sliding groove 11.
[0028] A stop block 7 is provided at one end of the measuring scale 3 outside the sliding groove 11 to prevent the measuring scale 3 from disengaging from the sliding groove 11.
[0029] The connection methods not mentioned in the present utility model are welding, clamping, riveting, hinging, threaded connection or bonding.
[0030] The above embodiments only represent the specific implementation manners of the present utility model. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
