Description

A kind of valve opening cuts groove depth detection device

Technical field

The utility model belongs to cubing technical field more particularly to a kind of valve opening cuts groove depth detection device.

Background technique

Engineering machinery is a kind of processing part of precision with hydraulic valve, due to technical requirements height design it is compact.Referring to Fig. 1, Wherein there is a valve design comparison special, slot is cut in the small inside of valve opening, and the size for cutting slot to bottom surface benchmark requires very high.It utilizes Traditional detection method can not be measured accurately.Presently, there are the problem of be that aperture d1 only has 12.37-12.63mm, cut groove width d2 For 0.99-1.07mm, the depth dimensions d3 for needing to detect groove to benchmark (A benchmark) is 1.0-1.13mm, general buckle depth Ruler is unable to measure.It is measured after mainly passing through dissection part early period, cost is very high, and product quality risk is very big.To subtract Low cost avoids dissection from detecting, and design specialized cubing, carries out detection control to product at any time in response to this problem.To promotion product Quality is of great significance with detection efficiency.

Utility model content

The application aims to solve at least one of the technical problems existing in the prior art.For this purpose, the purpose of this utility model One of be to provide a kind of valve opening easy to use, easy to operate and cut groove depth detection device.

In order to solve the above technical problems, the technical solution adopted by the utility model is:

A kind of valve opening cuts groove depth detection device, including mandrel component and the instrument group being arranged on the mandrel component Part；

The mandrel component includes contour sleeve and plug, and the plug is set in the sleeve and can be along quill To sliding, the plug bottom sidewall has extended to form hook plate, and the bottom face of the hook plate is concordant with the bottom face of the plug, The sleeve bottom end face is equipped with the evacuation notch axially extended, and the hook plate extend out to the sleeve from the evacuation notch Outside；

The instrument cluster includes dial gauge and set folder, and the set folder is placed on the top end face of the sleeve, and described hundred The top for dividing table to be installed in the set folder, the set folder are equipped with the through-hole for penetrating through its upper and lower end face, the measurement of the dial gauge Bar is arranged in the through-hole and plug described in measuring head face.

Further, the side wall of the set folder is equipped with bolt hole, and the dial gauge is fixed on set by clamping screw On folder.

Further, when the bottom face of the measuring head is concordant with the lower end surface that the set presss from both sides, the dial gauge zero.

Further, the material of the sleeve and plug is GCr15, heat treatment hardness 58-62HRC.

Further, the fit clearance of the sleeve and plug is 0.01-0.02mm.

Further, the bottom face of the set folder is equipped at least one annular groove.

Compared with prior art, it when the utility model measures, is cut in slot by the way that hook plate to be caught in, avoids notch alignment hook plate Sleeve is put into valve body hole, and makes bottom surface fitting detection datum level, because plug is contour with sleeve, plug top is stretched from sleeve Distance out is the depth to be measured for cutting slot, the instrument cluster after high-ranking officers " 0 " on the top end face of sleeve, the bottom face of pipe clamp with Sleeve is in close contact, and plug drives measuring rod to move upwards, and is directly read using percentage list index and is cut groove depth size, and number is measured According to accurate, reliable.Measure-axis is polished after cooperating with sleeve by flat stone mill, no cumulative errors.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of hydraulic valve to be checked；

Fig. 2 is the structural schematic diagram of the utility model；

Fig. 3 is the utility model middle sleeve main view；

Fig. 4 is plug top view in the utility model.

Specific embodiment

The utility model is further described below in conjunction with the drawings and specific embodiments.

Referring to figures 1-4, in one embodiment, which cuts groove depth detection device, including mandrel component and setting exist Instrument cluster on the mandrel component.

Mandrel component includes the equal sleeve 1 and plug 2 of height, and sleeve 1 is the hollow structure of both ends open, 1 He of sleeve The upper and lower end face of plug 2 is horizontal plane (can wear into mirror surface), and the material of sleeve and plug is GCr15, and heat treatment hardness is 58-62HRC.Plug 2 is coaxially set in sleeve 1 and can slide axially along sleeve 1, and 2 bottom sidewall of plug has extended to form hook The bottom face of plate 3, hook plate 3 is concordant with the bottom face of plug 2, and 1 bottom face of sleeve is equipped with the evacuation notch 4 axially extended, Hook plate 3 is extend out to outside sleeve 1 from evacuation notch 4；The fit clearance of sleeve 1 and plug 2 can be 0.01-0.02mm.

Instrument cluster includes dial gauge 5 and set folder 6, and the bottom face of set folder 6 is the horizontal plane for keeping being in close contact with sleeve 1 (can wear into mirror surface), set folder 6 are placed on the top end face of sleeve 1, and placement here directly can place in addition or pass through it He connects connector, in the present embodiment by the way of directly placing.Dial gauge 5 passes through the lock through set folder side wall bolt hole Tight bolt 7 is fixed on set ogival sections, and set folder 6 is equipped with the through-hole for penetrating through its upper and lower end face, and the setting of measuring rod 8 of dial gauge 5 exists In through-hole and measuring head face plug 2.

Referring to Fig. 1, in another embodiment, the bottom face of set folder 6 is equipped at least one annular groove 9, and annular groove 9 is arranged The bottom of set folder 6 and the contact area of sleeve 1 can be reduced, so that the accuracy of measurement is improved, while at school " 0 ", it can also To reduce the contact area with correction reference face.

This valve opening cuts the detection process of groove depth detection device are as follows: step 1: detection depthmeter first in platform colonel " 0 ", When the bottom face of measuring head is concordant with the lower end surface of set folder 6, dial gauge 5 is zeroed；Step 2: being inserted into core in workpiece to be detected Stick 2, and hook plate 3 is caught in groove, 3 bottom face of hook plate is abutted with groove lower wall；Step 3: the evacuation notch 4 of sleeve is aligned Hook plate 3 makes 1 bottom surface of sleeve fitting detection datum level A by 1 coaxial package of sleeve outside plug 2, because plug 2 and sleeve 1 are contour, 2 top of plug is stretched out from 1 top of sleeve；Step 4: instrument cluster, the bottom face and set of set folder 6 are put on 1 top end face of sleeve 1 top end face of cylinder is in close contact, and plug 2 drives detection bar 8 to move upwards, and the displacement of detection bar 8 is the depth of hook groove to be measured, The displacement of detection bar 8 is shown by dial gauge, is directly read by pointer and is cut groove depth size.

The utility model has the advantages that structure is simple, easy to use, when plug and sleeve wears away, it is only necessary to by plug It is polished with after sleeve cooperation by flat stone mill, reusable, no cumulative errors.

Above-described embodiment is only to clearly demonstrate examples for clearly illustrating the present invention, rather than the restriction to embodiment. For those of ordinary skill in the art, other various forms of variations can also be made on the basis of the above description Or it changes.Here without can not be also exhaustive to all embodiments.And the obvious variation thus amplified out Or it changes among still in the protection scope of the utility model.
