Description
Technical field
The utility model belongs to Machine Design, size detection field, and in particular to a kind of adjustable height V-type of T-type screw thread
Block.
Background technology
It is a kind of common support that V-block, which is supported in size detection, is used as measuring basis and to measured workpiece
Weight bearing.Especially in geometric tolerance measurement, V-block can ensure the axis horizontal of measured workpiece and the survey of workpiece
Position is measured, it can be as the transmission of measuring basis.When floating heap fuel assembly in ocean detects, because of two reference position of fuel assembly
Diameter is different, is supporting reference position using the V-block of sustained height, tested measure feature is caused to be unable to measure cylindricity and cylinder
Bus straight line degree.Therefore, it is necessary to design a set of height-adjustable V-block, and according to the weight of support fuel assembly, support
Weight needs, in 100Kg or more, to support adjustable height in 0~50mm.
In this design, the advantage for having used T-type screw thread load capacity big, and combine being designed in vertical direction for screw thread
Performance for adjusting height preferably resolves the property that measured workpiece weight is big, and the highly desirable height of datum axis is adjusted
It can require.
Invention content
The purpose of this utility model is that：It is surveyed in geometric tolerances such as axial workpiece concentricity, cylinder bus straight line degree, bounces
When amount, realize that V-block height can be adjusted in a certain range.
The technical solution of the utility model is as follows：A kind of adjustable height V-block of T-type screw thread, including pedestal, pedestal pass through
Bolt is connect with detection platform；Two guide plates are arranged in parallel in the both sides of pedestal, guide plate is equipped with vertical guide groove；
Pedestal is equipped with bearing, and bearing outer ring is fixed on pedestal, the lower end of the inner ring connecting T-shaped threaded post of bearing, T-type threaded post it is upper
End connection V-block, the center of the V-block are equipped with T-type internal thread hole, and T-type threaded post passes through T-type internal thread hole and V-block
Cooperation；The V-block is located between two guide plates, and when turning T-type threaded post, V-block can be in guide groove up and down
Movement.
The middle part of the T-type threaded post is equipped with hexangle type cylinder, is rotated with spanner easy to use, and then adjusts V
The height of type block.
The guide plate is fixed on the base by soket head cap screw, ensures the guiding of vertical direction.
The V-type angle of the V-block is 90 °.
The V-type angle of the V-block is 120 °.
The remarkable result of the utility model is：Height function is adjusted using T-type stud in the utility model, compensates for solid
Determine the defect that height V-block height can not be adjusted, consistent function can be adjusted by realizing different height V-block height.The V-type
Block height is adjusted simply, and use is easy to operate.
