Abstract

The utility model discloses a detection device of bottom taper of a valve core. The detection device comprises a base, a stand column, a first baffle, a second baffle, a sleeve, a limiting shaft, a connection plate and a dial indicator, wherein the stand column, the first baffle and the second baffle are fixedly connected with the base; the sleeve is sleeved on the stand column; the limiting shaft is used for braking the relative motion between the sleeve and the column; the connection plate is in rotary threaded connection with the limiting shaft; the shell of the dial indicator is fixedly connected with the connecting plate; and the first baffle, the second baffle and the measuring head of the dial indicator form an accommodating space for detecting the valve core. The detection device disclosed by the utility model has higher precision during use, can effectively detect the taper of the bottom of the valve core, thereby sorting out qualified products and unqualified products.

Description

A kind of valve inside bottom tapering pick-up unit

Technical field

The utility model relates to a kind of valve inside bottom tapering pick-up unit.

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, and whether one of them parameter up to standard is exactly the tapering of the valve inside bottom conical surface to check its processing, after product machines; Quality inspection personnel need take the bottom conical surface of the valve inside bottom conical surface and standard component to compare; In actual comparison process, because the special construction of valve inside makes that valve inside is difficult to be positioned; Increase comparison difficulty and degree of accuracy, demand urgently improving.

The utility model content

The utility model provides a kind of valve inside bottom tapering pick-up unit, can the tapering of valve inside bottom effectively be detected.

The utility model solves the problems of the technologies described above through following technical scheme; The utility model proposes a kind of valve inside bottom tapering pick-up unit; The limit shaft of relative motion between the sleeve pipe, the said sleeve pipe of braking that comprise base, is fixedly connected column and first baffle plate and second baffle, the said column of socket of said base and said column, rotate the be spirally connected web joint of said limit shaft, the dial gauge that its shell is fixedly connected said web joint, form the spatial accommodation of the said valve inside of detection between the gauge head three of said first baffle plate, said second baffle, said dial gauge.

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

The use of the utility model has higher degree of accuracy, can the tapering of valve inside bottom effectively be detected, thereby picks out certified products and unacceptable product.

Description of drawings

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

Fig. 1 is the three-dimensional structure diagram of embodiment 1;

Fig. 2 is the vertical view of embodiment 1;

Embodiment

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

Embodiment 1

A kind of valve inside bottom tapering pick-up unit comprises the spatial accommodation of formation detection valve inside 2 between gauge head 32 threes of the limit shaft 6 of

sleeve pipe

9,7 relative motions of brake casing 9 and column of base 1, the column 7 that is fixedly connected base 1 and first baffle plate 8 and second baffle 5, socket column 7, the web joint 4 that rotates the limit shaft 6 that is spirally connected, dial gauge that its shell 31 is fixedly connected web joint 43, the first baffle plates 8, second baffle 5, dial gauge 3; Because the bottom 21 of valve inside 2 is provided with the conical surface, the bottom surface is fixed on the base 1 with second baffle 5 for circle shape, first baffle plate 8; Form the angle of restriction valve inside 2 positions between first baffle plate 8 and the second baffle 5; Because dial gauge 3 can move up and down with respect to column 7, also can rotate with respect to limit shaft 6, so at first fix through the bottom surface of

first baffle plate

8 and 5 pairs of standard components of second baffle; Simultaneously; The front end of the gauge head 32 of dial gauge 3 is close on the conical surface of standard component, then gauge head 32 positions of dial gauge 3 and dial gauge 3 is fixed, when whether the conical surface that detects finished product valve inside 2 is qualified; Only need finished product valve inside 2 be placed into the position that the bottom is blocked by first baffle plate 8 and second baffle 5; Then through reading reading on the dial gauge 3 to the conical surface of judging these finished product valve inside 2 bottoms error with respect to standard component, if error in allowed band, then this finished product valve inside 2 is a pieces O.K.; If exceed the error range of permission; Then this finished product valve inside 2 is defective, so, can judge promptly whether finished product valve inside 2 is qualified; Testing process is simple, is suitable for mass detection.

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.

Claims

1. valve inside bottom tapering pick-up unit; It is characterized in that; The limit shaft of relative motion between the sleeve pipe, the said sleeve pipe of braking that comprise base, is fixedly connected column and first baffle plate and second baffle, the said column of socket of said base and said column, rotate the be spirally connected web joint of said limit shaft, the dial gauge that its shell is fixedly connected said web joint, form the spatial accommodation of the said valve inside of detection between the gauge head three of said first baffle plate, said second baffle, said dial gauge.
