Abstract
The utility model provides an axle sleeve internal diameter detects uses gauge head, includes the gauge head body, has seted up the mounting hole on the gauge head body, mounting hole and the coaxial setting of gauge head body, and the key is: the shape of gauge head body be cylindrical. The processing technology of gauge head is simple, and axle sleeve internal diameter and face of cylinder contacting area's size is all detected, and detection position is an area, and the detection position of gauge head is minimum, and this position is less than the inner chamfering of axle sleeve, can detect the axle sleeve internal diameter the most marginal position in both ends in the position apart from axle sleeve terminal surface 0.5mm height, if there is the undressed condition to the end at both ends, can be detected completely to guarantee the accuracy of axle sleeve internal diameter detection, avoided both ends processing defective work come into the market not in place conscientiously.
Description
Technical field
The utility model belongs to sleeve diameter checkout equipment technical field, relates to a kind of sleeve diameter detection gauge head.
Background technology
Axle sleeve is as a kind of component of machine, be widely used in industrial occasions, and the accuracy that sleeve diameter detects ensures that sleeve diameter and bearing pin reach the basic guarantee of design gaps, especially the two ends of sleeve diameter easily produce processing not risk to the end in process, two ends processing can directly not cause to the end bearing pin and sleeve diameter gap too small, even cannot normally load, as shown in Figure 1, there is following defect in existing sleeve diameter detection gauge head:
A, gauge head detect position thickness and only have 0.3mm, detection axis can only overlap an axial line;
The check point of b, gauge head is in the position apart from end face 2mm height, the position at most edge, axle sleeve two ends cannot be detected, cause sleeve diameter two ends to process not defective situation to the end cannot be detected, unacceptable product comes into the market, such axle sleeve is once load bore, and bearing pin and sleeve diameter tolerance clearance cannot ensure, even bearing pin cannot load, and axle sleeve external diameter and bore are interference fit, be difficult to take out once load.
Therefore for existing gauge head Problems existing set forth above, need to make further improvements gauge head.
Summary of the invention
The utility model, in order to overcome the defect of prior art, devises a kind of sleeve diameter detection gauge head, can detect sleeve diameter two ends processing not situation to the end, ensure the accuracy that sleeve diameter detects.
The concrete technical scheme that the utility model is taked is: a kind of sleeve diameter detection gauge head, comprises gauge head body, gauge head body offers mounting hole, and mounting hole and gauge head body are coaxially arranged, and key is: the shape of described gauge head body is cylindrical.
Wall thickness >=the 1mm of described gauge head body.
Described gauge head body height is vertically more than 1mm.
The diameter of described mounting hole is more than 3mm, and the diameter of gauge head body is more than 5mm.
The beneficial effects of the utility model are: the processing technology of gauge head is simple, the size at sleeve diameter and Cylindrical Surfaces Contact position is all detected, detecting position is set to a band, the detection position of gauge head is minimum in the position apart from end face of shaft bush 0.5mm height, this position is lower than chamfering in axle sleeve, the position at most edge, sleeve diameter two ends can be detected, if there is undressed situation to the end at two ends, can be detected completely, thus ensure that the accuracy that sleeve diameter detects, conscientiously avoid two ends to process unacceptable product not in place and come into the market.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing gauge head.
Fig. 2 is structural representation of the present utility model.
In accompanying drawing, 1 represents gauge head body, and 2 represent mounting hole.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is elaborated:
Specific embodiment, as shown in Figure 2, a kind of sleeve diameter detection gauge head, comprises gauge head body 1, gauge head body 1 offers mounting hole 2, mounting hole 2 and gauge head body 1 are coaxially arranged, the shape of gauge head body 1 is cylindrical, and the upper surface of gauge head body 1 is provided with chamfering, and lower surface does not have chamfering, the lower surface of gauge head body 1 is flushed with the lower surface of axle sleeve, the lowermost end of axle sleeve can be detected.Wall thickness >=the 1mm of gauge head body 1, the difference >=1mm namely between the radius of gauge head body 1 and the radius of mounting hole 2, gauge head body 1 height is vertically more than 1mm, and the diameter of mounting hole 2 is more than 3mm, and the diameter of gauge head body 1 is more than 5mm.During detection, gauge head is inserted in axle sleeve, the size of sleeve diameter and gauge head contact site is all detected, detecting position is set to the position corresponding with face of cylinder profile height, be a band, the detection position of gauge head is in the position apart from end face of shaft bush 0.5mm height, this position is lower than chamfering in axle sleeve, the position at most edge, sleeve diameter two ends can be detected, if there is undressed situation to the end at two ends, can be detected completely, thus ensure that the accuracy that sleeve diameter detects, conscientiously avoid two ends to process unacceptable product not in place and come into the market.
