Description

Low noise ball bearing retainer mould ball-and-socket depth calibrator

Technical field

The utility model belongs to retainer mould pick-up unit, mainly proposes a kind of low noise ball bearing retainer mould ball-and-socket depth calibrator.

Background technology

In the present domestic bearing industry, the ribbon retainer precision in the ball bearing is more and more higher, and the ribbon retainer shaping mould is used for last one trimming of ribbon retainer, and its crucial mould is a correcting die, whole ball seat.The ball-and-socket that all has 15～20 quantity not wait on these two kinds of moulds, ball-and-socket size SR tolerance≤0.01mm, roughness Ra0.1, degree of depth h tolerance 0.01mm, 20 ball-and-socket degree of depth require phase mutual deviation≤0.005～0.01mm.Its measurement is to take dial gauge all the time, promptly dial gauge is fixed on the support, personnel selection is the following pointer of the pulling dial gauge h that fathoms on hand, and the drawback that this kind detection mode exists is: 1, to represent to be worth precision be 0.01 to dial gauge,, can't guarantee ball-and-socket phase mutual deviation precision.2, the dial gauge range is 6mm, and ball-and-socket degree of depth h can't detect during greater than 6mm.When 3, the ball-and-socket degree of depth was dark, dial gauge sensitivity reduced, and can not make zero, and measurement result poor reliability, the degree of depth are dark more, and the measurement result reliability is poor more.

Summary of the invention

The purpose of this utility model is to propose a kind of low noise ball bearing retainer mould ball-and-socket depth calibrator, makes it reach Testing requirement from precision and others.

The technical pattern that the utility model proposes is: it is made up of measuring basis spare and measurement mechanism two parts, and its measuring basis spare comprises ball-and-socket depth block and standard block gauge group; The ball-and-socket depth block upper flat plate cross-arm that wherein has center pit is on ring mould, and the bottom is positioned at the endoporus of mould, and ball-and-socket depth block bottom is connected with support plate and the standard block gauge group is placed on the support plate; Measure portion mainly is made of measuring sonde, sounding rod, clock gauge and cantilever, column and fine-tuning nut, measuring sonde is positioned at an end of sounding rod and the other end of sounding rod is connected with cantilever by extension spring, the sounding rod endoporus is provided with bearing and bearing is bearing on the sleeve by axle, one end of clock gauge contacts with the sounding rod rear portion, cantilever is enclosed within on the column can move up and down and be provided with the adjusting tightening wheel that makes the cantilever location along column, and column is provided with the fine-tuning nut of adjusting cantilever height on column simultaneously.

The testing process of the utility model measuring instrument:

1, selects different ball-and-socket depth block according to the degree of depth of ball-and-socket on the mould, place it on the tested mould, according to ball-and-socket degree of depth choice criteria slip gauge group, the height that it is placed on the support plate is consistent with designed mould ball-and-socket depth dimensions, because the height of standard block gauge group is known through selecting, mould ball-and-socket depth design size is known.

2, regulate the tightening wheel, cantilever is moved up and down along column, measuring sonde is placed on the standard block gauge group, clock gauge is made zero by fine-tuning nut.

3, after clock gauge makes zero, ball-and-socket depth block, standard block gauge group are taken out from mould, at this moment measuring sonde is placed in the mould ball-and-socket, and contact ball-and-socket bottom, according to the clock gauge value, determine whether the ball-and-socket degree of depth is consistent with design size, or the error size.

4, behind ball-and-socket of mensuration, rotate tested mould, measure next ball-and-socket then, so analogize, just can survey whole ball-and-sockets.

The utility model measuring instrument has following characteristics:

1, overcomes the existing dial gauge that adopts and measure, realize that clock gauge detects, and is accurate to 0.002mm by 0.01mm on the precision, repeatable accuracy 0.003mm.

2, the positive and negative 0.10mm of clock gauge range, the design fine-tuning nut is realized the gauge outfit oscilaltion under the prerequisite that guarantees precision.

3, the ball-and-socket depth block of design differing heights, all ball-and-socket degree of depth of realization can both be measured on the range, and use the standard block gauge group, as the standard component assembly, for measurement provides standard.

4, She Ji fine-tuning nut can make instrument make zero.

Because can being controlled at measuring error and repeatable accuracy, above structural design guarantees that the ball-and-socket degree of depth is mutually in the requirement of mutual deviation precision.
