Abstract
The utility model discloses an external thread detector of a taper thread, comprising a caliper rule and an indicating gauge, wherein the indicating gauge (1) is fixedly installed at the front end of a fixed claw (4) of the caliper rule, and a measuring head (2) and a measuring rod of the indicating gauge are parallel to a rule rod (3) of the caliper rule; and the front end of a movable claw (5) of the caliper rule is fixedly provided with a measuring head (6), and the measuring head (6) corresponds to the measuring head (2) of the indicating gauge and is positioned on the same axis with the measuring rod of the indicating gauge. When used for measuring, the external thread detector continuously measures on the specified space along the conical generatrix of the same thread to be measured, and the reading difference of the continuous measurement is the taper of an external thread. The external thread detector has the advantages of simple structure and convenient use, can accurately detect the taper of the external thread, judge whether the thread taper of a product is qualified or not, and provide relevant revision parameters for thread-adjusting processing equipment in a processing process in time.
Description
Technical field
The utility model belongs to survey instrument, and what relate to is a kind of thread taper measuring instrument, particularly a kind of taper thread external thread detector.
Background technology
At present, normally used to the detection of tapering external thread tapering is ring thread gage, and it judges with the degree of tight distance whether screw thread is qualified, and testing result is a kind of qualitative conclusion, does not have the data of quantification.This ring thread gage only is a kind of testing tool at finished product, can't provide relevant revision parameter for adjusting process equipment in the process of screw thread.
Summary of the invention
The purpose of this utility model provides a kind of external thread detector of taper thread, it can measure the externally threaded tapering numerical value of taper thread intuitively, exactly, numerical value can judge accurately that not only whether qualified the tapering of this screw thread is thus, can also revise parameter accurately for timely adjustment process equipment in the process provides.
The technical scheme that realizes above-mentioned purpose is: a kind of external thread detector of taper thread, comprise slide calliper rule and an indicating gauge, and described indicating gauge is fixedly mounted on the fixed claw front end of slide calliper rule, and the measuring head of indicating gauge and sounding rod are parallel with slide calliper rule chi bar; The movable claw front end of slide calliper rule is installed with a measuring head, and this measuring head is corresponding with the measuring head of indicating gauge and be positioned on the same axis with the sounding rod of indicating gauge.
During measurement, on the spacing of regulation, carry out continuous coverage along same tested screw thread element of cone, be about to two measuring heads and be stuck in the same alveolus of tested screw thread bottom, read the indicating gauge maximal value, spacing continuous coverage in accordance with regulations then, the difference of the reading of continuous coverage are exactly externally threaded tapering.
The utility model simple structure, easy to use, can accurately detect externally threaded tapering, both can judge whether the thread taper of product is qualified, and can in process, in time provide the related amendments parameter, thereby improve product percent of pass for adjusting thread processing equipment.
Description of drawings
Fig. 1 is the front organigram of an embodiment of the utility model.
Among the figure: 1. digital display indicating gauge, 2. indicating gauge measuring head, 3. slide calliper rule chi bar, 4. slide calliper rule fixed claw, 5. slide calliper rule movable claw, 6. movable claw measuring head, 7. lock-screw.
Embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The external thread detector of the utility model taper thread is made up of slide calliper rule and a digital display indicating gauge.In the present embodiment, indicating gauge is a kind of digital display indicating gauge, fixed claw 4 front ends of slide calliper rule have a through hole, the parallel axes of this through hole is in slide calliper rule chi bar 3, the measuring head 2 and the sounding rod of digital display indicating gauge pass described through hole, and digital display indicating gauge 1 is fixed on the through hole and keeps the axis of sounding rod parallel with slide calliper rule chi bar 3; The front end of slide calliper rule movable claw 5 is installed with a measuring head 6, and the sounding rod of this measuring head and indicating gauge is positioned on the same axis, as shown in Figure 1.
During measurement, earlier the utility model measurer is stuck on the outer cone par identical 1 zeroing of digital display indicating gauge with tested major diameter of thread, screwing lock-screw 7 makes movable claw 5 fixing, then two measuring heads 2,6 are stuck in the complete first alveolus of tested screw thread bottom, movable claw measuring head 6 maintains static, and indicating gauge measuring head 2 along this screw thread circle swing, is read maximal value, spacing continuous coverage in accordance with regulations again, the difference of the reading of continuous coverage are exactly externally threaded tapering.
The utility model can be measured the externally threaded tapering of taper thread of different size by the bulb diameter dimension that changes two measuring heads 2,6.
Claims (2)
1. the external thread detector of a taper thread comprises slide calliper rule and an indicating gauge, it is characterized in that: described indicating gauge (1) is fixedly mounted on slide calliper rule fixed claw (4) front end, and indicating gauge measuring head (2) and sounding rod are parallel with slide calliper rule chi bar (3); Slide calliper rule movable claw (5) front end is installed with a measuring head (6), and this measuring head (6) is corresponding with indicating gauge measuring head (2) and be positioned on the same axis with the sounding rod of indicating gauge.
