Background
At present, the positions of the grooves in domestic hub bearing grinding and turning can be measured through height dimension conversion or by a template.
When the groove position is measured by the altimeter, the requirement on a bearing supporting point is high, and when the accurate turning is performed, the groove is turned first, and the accurate turning position is measured by using the outer diameter reference of the rough turning, so that the error is too large, and the accurate size cannot be measured. And during measurement, the gauge head rotates due to the fact that the gauge head is in contact with a workpiece, and measurement accuracy is affected.
The method of measuring by a template has many defects in which the manufacturability of the template is poor and thus the accuracy is poor. Secondly, the sample plate has high requirements on quality of inspection staff, and cannot be well popularized.

The upper part and the lower part of the measuring head in the technical proposal of the invention are rectangular or cylindrical, and the grooves on both sides are rectangular grooves.
According to the technical scheme, the lower part of the measuring head is close to the chamfer angle of the outer side part of the steel ball.
In the technical scheme of the invention, a steel ball mounting hole is formed in the center of the bottom of the measuring head, and a steel ball is pressed in the steel ball mounting hole.
The former template structure is divided into three parts, wherein the template R part replaces the linear cutting R by a steel ball, the template thin measuring rod is replaced by a wide measuring rod, and the half measuring head part of the T-shaped groove measuring rod fixing rod is connected with the measuring rod. The gauge head part is processed by steel balls, the manufacturability is good, the grinding size is controllable, the tolerance of 0.005mm can be reached, and the precision is far higher than that of the traditional template. The measuring head part is connected with the measuring rod by a measuring head fixing rod, the position size of the measuring head part is adjustable, and the position size precision of the gauge can be within the tolerance of 0.005 mm. The wide measuring rod is used for replacing the narrow measuring rod, so that the result can be more conveniently checked.
The measuring head, the measuring head fixing rod and the measuring rod can be easily machined by machining. The T-shaped groove is processed on the measuring head fixing rod, so that the measuring head can be conveniently fixed.
The invention has the following positive effects:
the groove position can be accurately controlled when the groove is finely turned, so that the grinding amount of grinding is reduced, the risk that products with poor R in batches are processed after the grinding wheel is collided during grinding is reduced, the grinding production efficiency is improved, and the quality of the grinding products is improved.

Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 2, a hub unit groove position detection gauge of the present invention includes a gauge head 2, a gauge head fixing bar 3, and a gauge bar 5. The center of the upper part of the measuring head 2 is provided with a threaded hole and a measuring head fixing screw 4, two sides of the middle part are provided with symmetrical grooves, and the center of the bottom is provided with a steel ball 1. The upper part and the lower part of the measuring head 2 are square bodies, and can also be cuboid or cylinder, and the grooves on two sides are rectangular grooves. The center of the bottom of the measuring head 2 is provided with a steel ball mounting hole in which the steel ball 1 is pressed. The lower part of the measuring head 2 is close to the outer side chamfer of the steel ball 1. The measuring head fixing rod 3 is a cuboid, one side end of the measuring head fixing rod 3 is provided with a rectangular groove in the vertical direction, and two side walls of the rectangular groove are provided with symmetrical fixing rod through holes. The lower part of the measuring head fixing rod 3 is provided with a T-shaped groove in the horizontal direction, and the T-shaped groove is matched with grooves on the upper part and two sides of the measuring head 2. The upper part of the measuring head fixing rod 3 is provided with an adjusting groove communicated with the T-shaped groove, and the wall of the adjusting groove is provided with an adjusting groove through hole communicated with the rectangular groove. The measuring rod 5 is provided with a rectangular mounting groove matched with the rectangular groove, the inner side surface of the mounting groove is provided with a measuring rod adjusting through hole corresponding to the adjusting groove through hole, and the measuring rod 5 at the inner side of the mounting groove is provided with a measuring rod fixing through hole corresponding to the fixing rod through hole.
