SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is that current bearing inner race groove diameter measuring apparatu supports unstablely, can produce measuring error, perhaps the structure is complicated, provides a simple structure for this and supports stable radial ball bearing inner race groove diameter measuring apparatu.
In order to achieve the above object, the present invention provides the following technical solutions: the measuring instrument comprises a base, a base plate fixedly connected to the base, a horizontal open slot and a vertical open slot which are perpendicular to each other and point to the center of the base plate, a horizontal measuring head and a vertical measuring head which are respectively arranged in the horizontal open slot and the vertical open slot, a cross backer fixedly connected to the center of the base plate, a gauge head support connected to one side of the base plate through a bolt, a gauge head which is arranged on the gauge head support and points to the center of the base plate, and an extension line where the gauge head is located is superposed with an extension line where the horizontal open slot/the vertical open slot is located.
In the above scheme, two at least bolt fixing grooves are formed in the bottom of the gauge outfit support, corresponding bolt holes are formed in the side face of the substrate, and bolts connected with the screw holes in a threaded mode are installed in the bolt fixing grooves.
In the above scheme, the base is a triangular base, and the substrate is located on the longest side of the triangular base.
In the scheme, the number of the triangular bases is two, and the two triangular bases are respectively positioned at two sides of the substrate.
In the scheme, the base plate and the gauge head support are plates.
The utility model has the advantages that: simple structure and low cost. The bearing inner ring groove diameter measuring instrument disclosed by the patent is made of plates, the whole structure of the existing bearing inner ring groove diameter measuring instrument is an iron casting, and the processing technology difficulty is far greater than that of the product disclosed by the invention; the measurement precision is high, and the consistency of repeated measurement is stable. When the existing bearing inner ring measuring instrument is used for measuring, the inner ring is easy to axially swing, so that the groove diameter measuring value of the inner ring is inaccurate. The utility model discloses use the cross backer to increase and measure the structure rigidity, can not take place the swing in the inner circle rotation measurement, make to measure numerical value and be bearing inner circle channel center department diameter all the time, also can guarantee repetition measurement's uniformity simultaneously.
