Abstract
The utility model discloses a thread verticality measuring gauge, which comprises a measuring gauge handle, the measuring gauge handle is connected with a measuring column, the other end of measuring column is connected with a measuring gauge stud, the thread pitch diameter of which is a small taper degree, and the thread pitch diameter of the thread verticality measuring gauge stud adopts 1:50 taper degree. The thread pitch diameter dimension D at the middle point L/2 of the thread verticality measuring gauge stud is the go-end dimension of a standard thread plug gauge, so as to enable at least half of the length of the measuring gauge stud thread to be revolved in the bolt hole of a measured part, because the dimension at the rear end of the measuring gauge stud is larger than the no-go end dimension of the thread plug gauge, the full length cannot be revolved in the bolt hole of the measured part, certain elastic deformation is generated between the screwed measuring gauge thread and the bolt hole thread of the part, the matching gap of the thread is eliminated, thereby the measuring error is eliminated, the problem of the measuring error exiting in the prior art is solved, and the quality reliability of the mechanical part and the economic efficiency of an enterprise are improved. The manufacturing of the utility model is simple, and the usage is convenient and reliable.
Description
Technical field
The utility model belongs to the Machining Technology field, relates to a kind of thread measuring tool, is specifically related to a kind of screw thread verticality gauge.
Background technology
In the machine-building process, many important components of machine all are provided with threaded hole, installation requirement in order to ensure part, the footpath has all proposed the verticality requirement in the double thread hole, the detection of threaded hole verticality is checked by screw thread verticality gauge, during use, the threaded portion that will have the external thread gauge of step all screws in the threaded hole of workpiece, the external thread gauge table top pastes mutually with the screw end face, fill in table top and screw end clearance with the measurement clearance gauge, check the screw thread verticality by the numerical value of measuring its gap; Perhaps measuring external thread gauge platform outer face with dial gauge checks the screw thread verticality whether to meet the drawing requirement.But, because external thread gauge screws in threaded hole and exists the measuring error that Screw Thread Fit Clearance produces, make that threaded hole squareness measurement result is not accurate enough, so just produced the phenomenon that the part unacceptable product is judged to certified products, the part that input is installed and used exists hidden danger of quality; Also can produce the phenomenon that the part certified products is judged to unacceptable product, the erroneous judgement that causes has brought unnecessary loss for enterprise and society.
Summary of the invention
The purpose of this utility model provides a kind of screw thread verticality gauge, it has been eliminated screw thread verticality gauge and has screwed in the interior tolerance clearance of threaded hole, solve the measuring error problem that measurement result exists in the prior art, improved product quality and economic benefit of enterprises.
The technical scheme that the utility model adopted is, a kind of screw thread verticality gauge comprises the gauge handle, and its characteristics are that the gauge handle links to each other with measurement column, and the measurement column other end is that a little cone gauge double-screw bolt links to each other with the pitch diameter of thread.
Characteristics of the present utility model are that also the screw thread verticality gauge double-screw bolt pitch diameter of thread adopts 1: 50 tapering.
The pitch diameter of thread of screw thread verticality gauge gauge double-screw bolt point midway L/2 is of a size of standard thread feeler gauge go side size.
Measurement column also can be designed to a test desk.
The utility model is designed to a little tapering with the screw thread verticality gauge double-screw bolt pitch diameter of thread, during measurement, it screws in the threaded hole, after tightening gauge, produce certain elastic deformation between gauge double-screw bolt screw thread and part screw screw thread, eliminated the tolerance clearance of screw thread fully, screw thread fits tightly, eliminate measuring error, obtained real measurement data, guaranteed product quality.

Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
The structure of the utility model screw thread verticality gauge as depicted in figs. 1 and 2, comprise gauge handle 1, gauge handle 1 links to each other with measurement column 2, and measurement column 2 other ends are that a little cone gauge double-screw bolt 3 links to each other with the pitch diameter of thread, and screw thread verticality gauge gauge double-screw bolt 3 pitch diameters of thread adopt 1: 50 tapering; The gauge pitch diameter of thread D of screw thread verticality gauge gauge double-screw bolt 3 point midway L/2 is of a size of standard thread feeler gauge go side size.Like this, can guarantee that gauge double-screw bolt 3 has at least the screw thread of half length can screw in tested part 5 threaded holes, because gauge double-screw bolt 3 rearward end sizes are greater than plug thread gauge not-go-end size, gauge double-screw bolt 3 just can all not screwed in the threaded hole of tested part 5, after tightening gauge screw thread is fitted tightly, between gauge screw thread and part screw screw thread, produce certain elastic deformation, eliminated the tolerance clearance of screw thread fully, also eliminate measuring error, thereby measured the actual verticality of workpiece hole exactly.And original thread verticality gauge when detecting part threaded hole verticality as shown in Figure 3, be to measure the gap width of each point between tested part 5 threaded hole end faces and the test desk 4 with measuring clearance gauge, owing to have Screw Thread Fit Clearance between gauge double-screw bolt 3 screw threads and tested part 5 screw screw threads, loosening Huo Do strength phenomenon can appear behind the screw-in, will produce measuring error, the accuracy of component test will reduce.
The utility model detects part threaded hole verticality as shown in Figure 4, measurement and positioning requirement according to tested part 5, when threaded hole is in the horizontal survey position, screw thread verticality gauge gauge double-screw bolt 3 is screwed in the threaded hole of tested part 5, screw thread is tightened to fit tightly, by measure the numerical value of measurement column 2 Up Highway UHW each points with dial gauge 6, obtain the screw thread perpendicularity deviation.
As shown in Figure 5, threaded hole is in the vertical survey position, screw thread verticality gauge measurement column 2 also can be designed to a test desk 4, both can measure the plane of test desk 4 with dial gauge 6, obtain screw thread perpendicularity deviation value, also can measure between test desk 4 and the tested part 5 threaded hole end faces everywhere gap width, obtain screw thread perpendicularity deviation value with clearance gauge 7.
A kind of screw thread verticality gauge is provided, screw thread is vertically measured and is directly adopted 1: 50 little tapering in the male screw, the pitch diameter of thread dimension D of screw thread verticality gauge gauge double-screw bolt point midway L/2 is passed through the end size for the standard thread feeler gauge, the screw thread that is threaded into rare half length that can guarantee the gauge double-screw bolt can screw in the tested part threaded hole, because gauge double-screw bolt rearward end size is greater than plug thread gauge not-go-end size, the gauge double-screw bolt can all not screw in the threaded hole of tested part, tightening gauge fits tightly screw thread, produce certain elastic deformation between gauge screw thread and part screw screw thread, eliminated the tolerance clearance of screw thread fully, also eliminated measuring error, solved the problem of the measuring error that exists in the prior art, measure the actual verticality of workpiece hole exactly, guarantee the accuracy of component test, improve the q﹠r of mechanical component, also improved economic benefit of enterprises simultaneously.The utility model manufacturing is simple, and is easy to use and reliable.
