Abstract
The utility model provides a tool used for measuring the depth of a conical hole in a deep hole. The tool comprises a cylindrical correcting measurement tool and a depth ruler, wherein the depth ruler comprises a depth measurement screw, an index plate, a zero-position dial, a handle and locking screws. One end of the depth measurement screw is provided with a conical end corresponding to a standard conical surface structure required by a to-be-measured workpiece, and the other end of the depth measurement screw is provided with the index plate, the zero-position dial, and the handle, and is further provided with the cylindrical correcting measurement tool matched with the depth ruler. The tool is used for measuring the distance between an end face of the depth hole and a small end face of the conical hole in the deep hole, and can accurately measure the processing depth of the conical hole in the workpiece. The tool can ensure the consistency of the processing size through the timely measurement when the internal conical surface is processed, so that the sealing effect of the tool can be ensured, and the pass percent of the tool can be conveniently enhanced. Compared with the prior art, the tool has the advantages that the tool is simple in structure and convenient to use, and the tool can reduce the production cost of the factory and the labor intensity of workers.
Description
Technical field
The utility model belongs to employed survey instrument in a kind of machining. be specifically related to a kind of instrument that reflects conical bore conical surface diameter crudy by the distance of measuring conical bore small end face and reference field.
Background technology
Keep sealing when in the prior art, having many product requirements that the liquid in the runner is dammed.And utilize the inside and outside circle cone match to reach the packoff of sealing effectiveness, the effective dimensions of its inside and outside Cone fit is one of key factor of impact sealing.Therefore must immediately measure the conical bore size of in the deep hole of this product, processing.But because of without proprietary survey instrument, in the production, be difficult to detect the taper hole accurate size in the product deep hole, generally adopt trial assembly product after the processing to determine whether qualified method of processing dimension, increased production process, time-consuming, and rejection rate is higher.
Summary of the invention
It is a kind of simple in structure that goal of the invention of the present utility model is to provide, and the instrument that is used for measuring the conical bore degree of depth in the deep hole easy to use, this instrument can realize that processing is measured immediately to the circular conical surface in the deep hole, to guarantee the consistance of processing dimension.
The technical solution of the utility model is: comprise a drum type brake check and correction measurer, a pit gauge.Pit gauge is comprised of depth measurement screw rod, index plate, 0 index dial, handle, lock-screw.Depth measurement screw rod one end has the conical surface termination corresponding with the desired standard round cone structure of measured workpiece; The depth measurement screw rod other end is equipped with index plate, 0 index dial, handle.Also comprise a drum type brake check and correction measurer that is used with pit gauge.
The described depth measurement screw rod other end has three grades of steps, on the axle of first step external thread is arranged, and the threaded hole of index plate through its center is loaded on the external thread of first step; Fill 0 index dial on the second step, on 0 index dial a cylinder table is arranged, a radial hole is arranged on the cylinder table, lock-screw is housed in the radial hole; Fill handle on the 3rd step.
The utility model is used for measuring the conical bore small end face distance in outlet of deep hole end face and the hole, can accurately measure the conical bore working depth in the workpiece, by the instant measurement in man-hour of internal conical surface, guaranteed the consistance of processing dimension, thereby guarantee the product sealing effectiveness, be convenient to improve the qualification rate of product.Compared with prior art, simple in structure, easy to use, reduced trial assembly product after the processing to determine whether qualified operation of processing dimension, reduced the production cost of factory and workman's labour intensity.

Embodiment
Fig. 1 is the pit gauge structural drawing.Pit gauge is by depth measurement screw rod 1, index plate 2,0 index dial 3, handle 4, lock-screw 5 and form.Depth measurement screw rod 1 one ends have the conical surface termination 6 corresponding with the desired standard round cone structure of measured workpiece.The other end has three grades of steps, on the axle of first step external thread is arranged, and index plate 2 is loaded on the external thread of first step through the threaded hole at its center.Filling on the second step on 3,0 index dials 3 of 0 index dial has a cylinder table, and a radial hole is arranged on the cylinder table, and lock-screw 5 is housed in the radial hole, is used for 0 index dial 3 is fixed in second step.Dress handle 4 on the 3rd step.
Wherein, the external thread on threaded hole and the depth measurement screw rod 1 of index plate 2, handle 4 by self on the corresponding step cooperates, and 0 index dial 3 is by second step external cylindrical surface realization connection corresponding on inner cylinder face and the depth measurement screw rod 1.
Wherein, index plate 2 is implemented in by the screw thread pair with depth measurement screw rod 1 first step composition and has moving axially of certain limit on the depth measurement screw rod 1; Handle 4 is by realizing self locking with the screw thread pair of depth measurement screw rod 1 the 3rd step composition; 0 index dial 3 can rotate around depth measurement screw rod 1 second step when lock-screw 5 unclamps.
Wherein, when lock-screw 5 was tightened, the one end withstood on depth measurement screw rod 1 second step in arc groove corresponding to end surface shape with it.
Fig. 2 is index plate 2 structural drawing.
Fig. 3 is 0 index dial 3 structural drawing.
Fig. 4 is the drum type brake check and correction measurer 7 that is used with pit gauge.
Utilize first the measurement face of drum type brake check and correction measurer 7 calibration index plates 2 and the small end face distance of depth measurement screw rod 1 front end conical surface termination 6 before the measurement.Rotate simultaneously 0 index dial 3, make 0 line of 0 bit alignment index plate 2 of 0 index dial 3, then fix 0 index dial 3 with lock-screw 5, avoid it to rotate at depth measurement screw rod 1.
Measurement face with index plate 2 during measurement is adjacent to the workpiece hole end face, and then turning handle makes the conical surface of depth measurement screw rod 1 front end conical surface termination 6 and the depth error that the applying of the workpiece conical surface can be read by the indicated index plate scale mark of 0 bit line of 0 index dial 3 taper hole.
