Abstract

The utility model discloses a length detection device, which is used for length detection over the top of a valve core. The detection device comprises a base, a first bump and a dial indicator, wherein the first bump is partially outwards extended from the upper surface of the base; a housing of the dial indicator is fixed on the base through a connecting strip; a measuring head of the dial indicator points to a first clamping groove which is reserved on the first bump to position the top; and an interval for detecting the length of the top is reserved between the measuring head and the first clamping groove. The detection device also comprises a second bump which is partially outwards extended from the surface of the base. A second clamping groove for fixing the valve core is reserved on the second bump. According to the length detection device, the length of the top of the valve core can be effectively and conveniently detected, and accuracy is high.

Description

A kind of device for detecting length

Technical field

The utility model relates to a kind of device for detecting length.

Background technology

Valve inside is a kind of important auto parts and components, is a vitals of motor car engine, and the effect of valve inside is to be responsible in engine input air specially and to discharge waste gas after burning; One of most important performance of valve inside is exactly a sealing property, for realizing its sealing property, to itself and cooperating of miscellaneous part requiring very high; Requirement to its machining precision in actual process also can be very high, check its processing whether one of them parameter up to standard whether be exactly valve inside top length up to standard, if the valve inside top length is not up to standard; Possibly cause the strength of joint between valve inside and other web members not enough, influence its actual usability, have a kind of device for detecting length in the prior art; The length detection that is used for the valve inside top; First convexity that pick-up unit comprises base, extended outward by the base upper surface part, its shell are through the dial gauge of connection strap firm banking, and the gauge head of dial gauge points to and is opened in first protruding first draw-in groove of going up with the top, location, between gauge head and first draw-in groove, reserves the spacing of detection top length; This device for detecting length can detect the length at finished product valve inside top whether in allowed band; Yet the problem of its existence is: because valve inside is longer, and the junction between the valve inside and first draw-in groove is narrower; Make and use in the process of this equipment in reality; Be difficult to valve inside is carried out good fixing, influence operator's practical operation, demand urgently improving.

The utility model content

The utility model provides a kind of device for detecting length, not only can effectively detect the valve inside bottom lengths, and detect conveniently, has higher degree of accuracy.

The utility model solves the problems of the technologies described above through following technical scheme; The utility model proposes a kind of device for detecting length; The length detection that is used for the valve inside top; Said pick-up unit comprises that base, first convexity, its shell of being extended outward by said base upper surface part pass through the dial gauge that connection strap is fixed said base; The gauge head of said dial gauge points to and is opened in said first protruding the going up to locate first draw-in groove at said top; Between said gauge head and said first draw-in groove, reserve the spacing that detects said top length, said pick-up unit also comprises second convexity that is extended outward by said susceptor surface part, offers second draw-in groove of fixing said valve inside on said second convexity.

Preferably, the breach that is opened in said valve inside table wall can stretch in said first draw-in groove

Based on disclosing of above technical scheme, the utlity model has following beneficial effect:

The utility model not only can be realized the length at valve inside top is detected; And, in the process that the length to the valve inside top detects, valve inside is fixed through 2; Make in the actual detected process; Valve inside is more stable, and its detected value is more credible, and degree of accuracy is higher.

Description of drawings

Below in conjunction with accompanying drawing the utility model is done further explanation:

Fig. 1 is the structure diagram of embodiment 1;

Fig. 2 is the structure diagram of valve inside;

1, base; 2, dial gauge; 21, shell; 22, gauge head; 3, connection strap; 4, first convexity; 41, first draw-in groove; 5, valve inside; 51, breach; 52, top; 6, second convexity; 61, second draw-in groove.

Embodiment

Following embodiment 1 and Fig. 1-2 of combining is described further the utility model:

Embodiment 1

Embodiment 1 proposes a kind of device for detecting length, is used for the detection of the length a ' b ' at valve inside 5 tops 52, and first protruding 4, its shell 21 that pick-up unit comprises base 1, extended outward by base 1 upper surface part is through the dial gauge 2 of connection strap 3 firm bankings 1; The gauge head 22 of dial gauge 2 points to and is opened on first protruding 4 with first draw-in groove 41 at top 52, location, between gauge head 22 and first draw-in groove 41, reserves the spacing ab that detects top 22 length a ' b ', is opened in the breach 51 that valve inside 5 shows on the walls and can snaps in first draw-in groove 41; The front end of valve inside 5 standard components is withstood the gauge head 22 of dial gauge 2, and when design the utility model, spacing ab is less than the top 22 length a ' b ' of valve inside standard component; Because gauge head 22 can carry out elastic telescopic, can gauge head 22 be headed into forward after the segment distance, then the breach 51 on the table wall of valve inside 5 standard components is snapped in first draw-in groove 41; The other part of valve inside 5 standard components is snapped onto in second draw-in groove 61 of second convexity 6,, make in use because valve inside 5 standard components have been carried out the fixing of two positions; Valve inside 5 standard components are more stable, regulate dial gauge 2 then, with it as object of reference; In the process that finished product valve inside 5 is detected; Only need take similar operation, adopt the front end of finished product valve inside 5 that gauge head 22 is withstood, the breach of then table of finished product valve inside 5 being closed 51 snaps in first draw-in groove 41; Finished product valve inside 5 other parts are snapped onto in second draw-in groove 61 of second convexity 6; Owing to valve inside 5 standard components have been carried out the fixing of two positions, have made that in use finished product valve inside 5 is more stable; Observe the reading of dial gauge 2 then; Can judge promptly with the standard component of valve inside 5 and compare that the error in length at finished product valve inside 5 tops 52 is whether in allowed band, if the error in length at these finished product valve inside 5 tops 52 is in allowed band; This finished product valve inside 5 is certified products; If the error in length at the top 52 of this finished product valve inside 5 not in allowed band, then is a unacceptable product, the utility model can detect the length at finished product valve inside 5 tops 52 very easily whether in allowed band.

The utility model is not limited thereto embodiment, and the related realization assembly that is the basis with the utility model thought is all in the protection domain of the utility model.
