Description

A kind of rigidity Simple measurement device of crossed roller turntable bearing

Technical field

The utility model belongs to crossed roller turntable bearing field of measuring technique, particularly relates to a kind of rigidity Simple measurement device of crossed roller turntable bearing.

Background technology

So-called rigidity refers to that component of machine is in the ability by resistance to deformation during External Force Acting, carrys out indirect inspection by the displacement measuring parts stress deformation.At present, bearing industry has the instrument can measuring rigidity at home, but device more complicated, price, testing expense is high, and needs to do special frock clamp before test, and method of testing is more loaded down with trivial details, test period is slow, also through complicated value computing, will be only applicable to single-piece test.Be not suitable for the user demand of product in batch inside workshop.In addition, also the method adopting theory calculate is had, the method is subject to bearing parts physical dimension, the restriction of the factors such as material, heat treatment process parameter and method, parts machining process flow process, accurately can not obtain the practical stiffness numerical value of bearing, especially for the bearing of accurate medical treatment device, the service precision of the value effect final host computer of its rigidity and the accuracy of host test result, so the test of this stiffness term object is particularly important.

Summary of the invention

In order to solve the problem of the measurement difficulty of prior art centre bearer rigidity, the purpose of this utility model is to provide a kind of rigidity Simple measurement device of crossed roller turntable bearing.

In order to realize foregoing invention object, the utility model adopts technical scheme as described below:

A kind of rigidity Simple measurement device of crossed roller turntable bearing, comprise base, turntable bearing, holder, semi-girder, clock gauge A and clock gauge B, the inner ring of turntable bearing is fixedly connected with base, the outer ring of turntable bearing is connected with holder, described semi-girder comprises vertical beam and crossbeam, vertical beam lower end is fixedly connected on holder upper surface, and vertical beam upper end is vertically connected with crossbeam; Clock gauge A and clock gauge B is fixedly connected on base respectively by dial framework, and the gauge head top of clock gauge A is attached on the outer ring of turntable bearing, and the gauge head top of clock gauge B is attached on vertical beam.

Further, the central axis of the vertical beam of described semi-girder and the central axes of turntable bearing.

Further, the gauge head top of described clock gauge A is attached to the middle part of turntable bearing outer ring.

Further, the gauge head top of described clock gauge B is attached to the center of vertical beam.

Further, described vertical beam is welded on holder.

Owing to adopting technique scheme, the utility model has following superiority:

The utility model is by imposed load on the crossbeam of semi-girder, axial displacement and the radial displacement of turntable bearing can be measured by clock gauge A and clock gauge B, and then axis and the radial rigidity numerical value of turntable bearing is drawn by rigidity formula, structure is simple, easy and simple to handle, measures quick and precisely.

Accompanying drawing explanation

Fig. 1 is structural representation of the present utility model;

In figure: 1-base; 2-turntable bearing; 3-holder; 4-clock gauge A; 5-clock gauge B; 6-vertical beam; 7-crossbeam; 8-load.

Embodiment

As shown in Figure 1, a kind of rigidity Simple measurement device of crossed roller turntable bearing, comprise base 1, turntable bearing 2, holder 3, semi-girder, clock gauge A4 and clock gauge B5, the inner ring of turntable bearing 2 is fixedly connected with by screw with base 1, outer ring and the holder 3 of turntable bearing 2 are connected by screw, described semi-girder comprises vertical beam 6 and crossbeam 7, vertical beam 6 lower end is fixedly connected on holder 3 upper surface, vertical beam 6 upper end is vertically connected with crossbeam 7, crossbeam 7 and the junction of vertical beam 6 are provided with reinforcement, ensure that integral rigidity is in order to avoid affect test result; Clock gauge A4 and clock gauge B5 is fixedly connected on base respectively by dial framework, and the gauge head top of clock gauge A is attached on the outer ring of turntable bearing, and the gauge head top of clock gauge B is attached on vertical beam.

The central axis of the vertical beam 6 of described semi-girder and the central axes of turntable bearing 2.

The gauge head top of described clock gauge A4 is attached to the middle part of turntable bearing 2 outer ring.

The gauge head top of described clock gauge B5 is attached to the center of vertical beam 6.

Described vertical beam is welded on holder.

The utility model is when embody rule, different loads △ P is applied by the punishment of fixed range on crossbeam level, the radial displacement △ S of bearing outside diameter is being measured by clock gauge A, by Rigidity Calculation formula K=△ P/ △ S, draw the radial rigidity numerical value K of bearing, the central axis of displacement △ S1 due to vertical beam and the central axes of turntable bearing of vertical beam skew is measured by clock gauge B, therefore, the axial displacement of △ S1 and turntable bearing, and then the axial rigidity numerical value K1 of bearing is drawn by Rigidity Calculation formula, the axial rigidity of bearing can be calculated by K and K1.

In order to ensure the accuracy of measurement result, in measuring process, often hanging a load and all will record the numerical value of clock gauge A, B, turntable bearing is rotated at every turn 90 ° of measurements once each circle all to survey 4 times, record weekly 8 secondary data.
