Abstract
The utility model discloses a coaxiality plug gauge for the internal thread and the inner hole of a cylinder barrel, which belongs to the field of machining inspection for hydraulic cylinders. The coaxiality plug gauge comprises a plug gauge and a handle, wherein the plug gauge is installed on the handle; an axial location sleeve extending forwards is arranged in the front direction of the thread of the plug gauge; and the thread of the plug gauge is fitted with the internal thread of the cylinder barrel, and the axial location sleeve is fitted with the inner hole of the cylinder barrel. The use method and principle are as follows: during inspection, if the axial location sleeve in front of the plug gauge can enter in the inner hole of the cylinder barrel, and the thread of the plug gauge can be screwed in the internal thread of the cylinder barrel, then the coaxiality between the internal thread of the cylinder barrel and the inner hole of the cylinder barrel is qualified; or else, the coaxiality is unqualified. According to the coaxiality plug gauge, the shortage that only thread specification can be inspected, of the traditional thread plug gauge, is improved; and the coaxiality plug gauge is capable of conveniently measuring the coaxiality deviation between the internal thread of the cylinder barrel and the inner hole of the cylinder barrel, simple in structure, and convenient to operate, thus shortening the inspection time, reducing the inspection difficulty, and increasing the production efficiency.
Description
Technical field
The utility model relates to a kind of feeler gauge, specifically is a kind of feeler gauge that detects cylinder barrel internal thread and cylinder barrel endoporus right alignment, belongs to special use and tests the tool field.Be specially adapted to the detection of cylinder barrel internal thread and cylinder barrel endoporus right alignment.
Background technology
At present, its structure of feeler gauge only is made of external thread.At home, hydraulic cylinder cylinder barrel internal thread and cylinder barrel endoporus right alignment detect and are mostly that the corresponding feeler gauge of screwing on utilizes dial gauge to beat the cylinder barrel endoporus and the feeler gauge beating degree detects internal thread and cylinder barrel endoporus right alignment after the correction of lathe secondary.This kind mode inefficiency, and take the machined into time, influence production efficiency.
Summary of the invention
The purpose of this utility model provides a kind of convenient to use, can check the feeler gauge of cylinder barrel internal thread and cylinder barrel endoporus right alignment.
The utility model is realized with following technical scheme: a kind of feeler gauge that detects cylinder barrel internal thread and cylinder barrel endoporus right alignment, comprise feeler gauge, and also comprise handle, described feeler gauge is installed on the handle; Be extended with an axial location cover forward in the place ahead of feeler gauge screw thread; Described feeler gauge screw thread and cylinder barrel screw-internal thread fit, described axial location cover cooperates with the cylinder barrel endoporus.
By cooperating of feeler gauge screw thread and axial location cover part and cylinder barrel internal thread and cylinder barrel endoporus, can Direct Test cylinder barrel internal thread and cylinder barrel endoporus right alignment.Use of the present utility model, replaced in the past lathe on the secondary, twist feeler gauge, the method of utilizing dial gauge to survey cylinder barrel endoporus and regular surface gauge beating degree detects the mode of right alignment, not only alleviated labor strength and the artificial collimation error, improved accuracy of detection, and machined owing to feeler gauge front end axial location cover part is divided into once being installed with the feeler gauge external thread part, with respect to the secondary beat degree that is installed, the right alignment testing accuracy is higher.
The beneficial effects of the utility model are: this novel feeler gauge, only need on the Workpiece storage frame, just to verify cylinder barrel internal thread and cylinder barrel endoporus right alignment, and can accurately check screw thread 6H grade and 0.04 right alignment requirement thereof.Well having solved needs gland to join car cylinder barrel internal thread or needs secondary to proofread and correct the problem that right alignment is detected in the back at lathe, and it is convenient to operation, has shortened proving time and check difficulty greatly.Simple to operation, saved lathe verification cost on the secondary, improved production efficiency greatly.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the utility model feeler gauge structural representation.
Among the figure: 1, handle, 2, feeler gauge, 3, cylinder barrel, 4, locating sleeve.
As shown in Figure 1, the feeler gauge of detection cylinder barrel internal thread of the present utility model and cylinder barrel endoporus right alignment comprises handle 1 and feeler gauge 2; Handle 1 conveniently is screwed into feeler gauge in the cylinder barrel 3.Be extended with axial location cover 4 forward in the place ahead of feeler gauge screw thread; Feeler gauge screw thread and cylinder barrel screw-internal thread fit, axial location cover 4 cooperate with cylinder barrel 3 endoporus.Feeler gauge 2 screw threads and axial location cover part once are installed and machine, and the two coaxial relation that has can play good test effect to the internal thread of cylinder barrel 3 and the right alignment of endoporus.
Using method and principle are: when testing, if the axial location in feeler gauge the place ahead cover part can enter the cylinder barrel endoporus, and the feeler gauge screw thread can be screwed onto the cylinder barrel internal thread, and then cylinder barrel internal thread and cylinder barrel endoporus right alignment are qualified, otherwise defective.
