Abstract

The utility model discloses a valve bounce gauge, which aims to overcome the defect that the measured valve in the prior art has bad positioning precision. The brief and accurate positioning datum is adopted, the axial positioning is increased and the measuring precision is improved. The key point is reflected that: the valve bounce gauge comprises a base; the two sides of the same common tangent plane vertical to the base are orderly symmetrically fixed with two pairs of the same spherical pads; the other single spherical pad is fixed on the base; the centre of a sphere of the single spherical pad is arranged in the above common tangent plane; each pair of the two pairs of the same spherical pads are formed in such a way that the same steel balls are symmetrically arranged at the two side of the same common tangent plane and tangential; the distance between the two pairs of the same spherical pads is one fourth to three fourth of the length of the measured valve stem; the distance from the single spherical pad to a pair of the spherical pads closest thereto is one fifth to three fifth of the length of the valve stem. Due to the adoption of the valve bounce gauge , the positioning stability of the valve is increased, the axial motion of the valve is controlled and the detection function for the face bounce is increased.

Description

The valve cubing of beating
Technical field
The utility model belongs to engine art, specifically relates to a kind of pick-up unit of engine valve.
Background technology
The development of car engine machine technology, to the also progressively upgrading of performance requirement of each parts, as the valve of one of vital part, its machining precision receives much concern from working as; Detection for valve, except general dimensional accuracy is measured, also to carry out strict detection to its shape and position relation, comprise the right alignment, each end face on the cylindricity on each section of valve face of cylinder, the relevant face of cylinder verticality to axis, in the actual detected, widespread use detects above-mentioned every accuracy of form and position requirement by detecting jerk value; The detection valve is beated, and prior art is to adopt to put valve stem on the V-type seat and slowly rotation, tests jerk value with testing tool facing to detected again, and this is the work of a very fine.China Patent No. ZL200420060543.4 for example, name is called the patent of valve detector, it comprises the PTO of table base, double as hold-down mechanism, the V-type anchor clamps and the inductance value instrument of placement determinand, and the PTO of double as hold-down mechanism and V-type anchor clamps are located at the both sides of table base respectively; One side of V-type anchor clamps is provided with two parallel electronic sensors at least, and an end of V-type anchor clamps also is provided with the oblique circle of the conical surface electronic sensor of beating; Described electronic sensor is connected with the inductance value instrument respectively by lead.This detector is used traditional V-type fixture support valve to be measured, but there is following deficiency in the mode of this detection:
1.V the V-type face machining precision of type anchor clamps is not high, the positioning reference plane low precision easily causes the valve stem swing with the support of V-type face in other words;
2.V the both sides of type anchor clamps are jagged or the precision of the fragile valve stem of wedge angle;
3. be easy to generate play back and forth, axial location low precision when valve rotates.
Summary of the invention
The utility model technical issues that need to address are, overcome prior art and measure valve the positioning reference plane low precision of V-type anchor clamps and the defective of axial location low precision, a kind of engine valve pick-up unit is provided, the employing brief positioning reference of trying one's best, and the increase axial location, improve measuring accuracy.
The purpose of this utility model is achieved by following technical proposals: a kind of valve cubing of beating, comprise base, prop up pad fixedly installing two pairs of identical spheries with the vertical same public tangent plane both sides of base symmetry successively, other have single sphere prop up the pad fixedly be located on the described base, this single sphere is propped up the centre of sphere of pad in above-mentioned public tangent plane, described two pairs of spheries prop up pad each to all being to be provided with and tangent along same public tangent plane symmetria bilateralis by two identical steel balls; Described two pairs of spheries prop up between the pad distance by survey valve stem length 1/4th to 3/4ths; Described single sphere prop up pad with respect to and its immediate a pair of sphere distance of propping up between the pad be 1/5th to 3/5ths of valve stem length.
Described sphere is propped up pad can be the standard steel ball, and steel ball size is 1~2 times of detected valve stem diameter.
As preferably, the steel ball size that described two pairs of spheries are propped up pad is all identical; The steel ball size that described single sphere is propped up pad props up the steel ball size of pad greater than described two pairs of spheries.
The beneficial effects of the utility model are:
1, increased the stability of valve location;
2, smooth steel ball can not damage valve;
3, the control valve moves axially;
4, increased measuring ability to face runout.
Description of drawings
Fig. 1 is the structural representation of a kind of embodiment of the utility model;
Fig. 2 is that synoptic diagram is looked on the right side of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and specific embodiments the utility model is further described.
Embodiment 1: in Fig. 1, a kind of valve cubing of beating, comprise base 1, prop up pad 2 fixedly installing two pairs of identical spheries with vertical same public tangent plane 5 both sides of base 1 symmetry successively, the two pairs of spheries prop up pad 2 each to all being to be provided with and tangent along same public tangent plane symmetria bilateralis by two identical steel balls 21, each of two pairs of steel balls all utilizes fixed bar 22 to fixedly connected with base 1, and the height of fixed bar 22 all equates; Other has single sphere to prop up pad 3 to utilize fixed bar 31 fixedly to be located on the base 1, and single sphere is propped up and filled up 3 the centre of sphere in above-mentioned public tangent plane; The two pairs of spheries prop up between the pad distance A by survey valve stem length 1/4th to 3/4ths; Single sphere prop up pad with respect to and its immediate a pair of sphere to prop up between the pad be 1/5th to 3/5ths of valve stem length apart from B.
Spherical pad can be the standard steel ball, also can be special non-standard steel ball, and the diameter of two pairs of steel balls is 1.5 times of detected valve stem diameter; The steel ball size that single sphere is propped up pad props up the steel ball size of pad greater than described two pairs of spheries; The diameter of single big steel ball is Φ 32mm, and the diameter of two pairs of small balls is Φ 14mm.Two pairs of small balls are tangent in pairs, and valve to be measured is placed on two pairs of steel balls, stability of rotation in the time of can making the valve test; The anti-air-stop gate test of single big steel ball produces axial float when rotating; The centre of sphere height of single big steel ball and the axis of tested valve are contour.
