Specifically, referring to fig. 1 to 3, the detecting stand 2 is provided with a reference step 21 and a first measurer 22, so that when the detecting stand 2 is inserted, the reference step 21 can be abutted against the step 11 to be detected of the shaft core inner hole 1, and the reference step 21 is provided with a reference plane 211, if the actual inclination angle of the inclined plane 112 to be detected is inconsistent with the preset inclination angle, a gap is formed between the plane 111 to be detected on the upper portion of the inclined plane 112 to be detected and the reference plane 211, at this time, a technician can detect the gap length through the first measurer 22, and determine whether the actual inclination angle of the inclined plane 112 to be detected is within a qualified range through a numerical value on the first measurer 22, so as to realize rapid detection of the inclined plane 112 to be detected.
Meanwhile, the detecting column 3 is provided with a detecting head 31 and a second measurer 32, the detecting head 31 and the detecting column 3 are arranged at an included angle, and the detecting head 31 is lifted and rotated together with the detecting column 3, so that a technician can move towards the direction of the step 11 to be detected and is abutted against the chamfer surface 113 of the step 11 to be detected by operating the lifting and rotating mode of the detecting head 31, wherein the second measurer 32 detects the height change of the detecting head 31 and feeds back the height change to the technician, so that the technician can judge whether the actual included angle between the chamfer surface 113 and the horizontal plane is in a qualified range or not, and the rapid detection of the chamfer surface 113 is realized.
It should be noted that, the inclined plane 112 to be measured is obliquely arranged from the connection position of the inclined plane 112 to be measured and the plane 111 to be measured to the axis direction of the shaft core inner hole 1, and the chamfer surface 113 is obliquely arranged to the inner wall direction of the shaft core inner hole 1, so as to play roles in positioning and fixing other components; if the actual inclination angle of the inclined plane 112 to be measured is outside the tolerance range of the preset inclination angle, and/or the actual included angle between the chamfer 113 and the horizontal plane is outside the tolerance range of the preset included angle, other components cannot be fully inserted into the inner bore 1 of the shaft core, so that the components are easy to separate from the inner bore 1 of the shaft core, and the precision of the final product is affected.
Further, in order to accurately detect whether the to-be-detected inclined plane 112 is qualified, the reference step 21 is provided with a reference inclined plane 212, the reference inclined plane 212 is connected with the reference plane 211, and the reference inclined plane 212 is located at the lower part of the reference plane 211, and the reference inclined plane 212 and the reference plane 211 are arranged at an included angle to each other so as to correspond to the structure and the position of the to-be-detected inclined plane 112 and the to-be-detected plane 111 in a preset state, so that when the actual inclination angle of the to-be-detected inclined plane 112 is inconsistent with the preset inclination angle, the reference inclined plane 212 cannot be completely attached to the to-be-detected inclined plane 112, and a gap is formed between the reference plane 211 located at the upper part of the reference inclined plane 212 and the to-be-detected plane 111 located at the upper part of the to-be-detected inclined plane 112, and the length of the gap can be fed back whether the actual inclination angle of the to-be-detected inclined plane 112 is within a qualified range. In order to further match with the inclined plane 112 to be measured, the reference inclined plane 212 is inclined from the connection position of the reference inclined plane 212 and the reference plane 211 toward the center direction of the detection base 2, so that the reference inclined plane 212 can abut against the inclined plane 112 to be measured of the step 11 to be measured.
Meanwhile, in order to accurately detect whether the chamfer surface 113 is qualified or not, in combination with fig. 3 and fig. 4, an abutment protrusion 311 is provided at the edge of the detecting head 31, and when the abutment protrusion 311 is located at a position where it can contact with the bottom of the reference step 21, the abutment protrusion 311 can just abut against the chamfer surface 113 in a preset state; therefore, when the actual included angle of the chamfer surface 113 is inconsistent with the preset included angle of the chamfer surface 113, the abutting protrusion 311 needs to rise or fall along with the detection head 31 to be abutted against the chamfer surface 113 in an actual state, and at this time, the height of the abutting protrusion 311 is changed, and the height change can be used for feeding back whether the actual included angle between the chamfer surface 113 and the horizontal plane is within the tolerance range of the preset included angle; therefore, the second measuring device 32 detects the change in the height of the abutment projection 311, and thereby feeds back whether the actual chamfer 113 is acceptable.
Wherein, because the detection column 3 can axially rotate relative to the detection pedestal 2, the detection head 31 can not only be lifted along with the detection column 3, but also rotate relative to the detection column 3, so that when the detection pedestal 2 is inserted into the shaft core inner hole 1, the detection head 31 can be accommodated in the detection pedestal 2 to avoid the step 11 to be detected; after the reference step 21 of the detection pedestal 2 abuts against the step 11 to be detected, the technician can rotate the detection head 31 to make the abutting protrusion 311 rotate along with the detection head 31 toward the chamfer surface 113 and abut against the chamfer surface 113, and then, the technician can adjust the height of the detection column 3 to make the abutting protrusion 311 just abut against the chamfer surface 113, so that the second measurer 32 detects the height change of the abutting protrusion 311.
Preferably, the detecting head 31 is further provided with a positioning column 312, the positioning column 312 is abutted against the detecting column 3, so that the detecting head 31 is not easy to rotate in a natural state, and the positioning column 312 is separated from the abutting protrusion 311 by a preset distance, so that the positioning column 312 and the abutting protrusion 311 are not interfered with each other.
It should be noted that, the first measurer 22 and the second measurer 32 may be digital display height gauges, so that a technician may measure the gap between the reference plane 211 and the plane 111 to be measured, and measure the height variation of the abutment protrusion 311.
On the other hand, in order to make the detection column 3 stably rotatable in the axial direction and vertically liftable, as shown in fig. 3 and 5, the detection pedestal 2 is provided with a mounting channel 231 and a positioning channel 232 which are communicated with each other in the vertical direction, the mounting channel 231 is located at the upper part of the positioning channel 232, and the diameter of the mounting channel 231 is larger than that of the positioning channel 232; correspondingly, the detecting column 3 includes a mounting section 331 and a positioning section 332 that are connected to each other in a vertical direction, the mounting section 331 is located at an upper portion of the positioning section 332, and a diameter of the mounting section 331 is larger than that of the positioning section 332, so that the positioning section 332 can be sequentially connected with the detecting head 31 through the mounting channel 231 and the positioning channel 232 in a shaft manner, thereby playing a role in positioning, preventing the detecting column 3 from moving left and right, and ensuring that the detecting column 3 can perform stable axial rotation; the mounting section 331 can only be inserted into the mounting channel 231, so as to limit the detecting column 3 and prevent the detecting column 3 from falling off when it is lifted up and down.
Further, in order to make the detection post 3 go up and down the back and can reset, the detection device of axle core hole step still includes extension spring 4, extension spring 4's one end with the junction looks butt of installation passageway 231 and location passageway 232, extension spring 4's the other end with the junction looks butt of installation section 331 and location section 332 makes detection post 3 when going up and down or rotating for detecting pedestal 2, extension spring 4 all can take place deformation to when detection post 3 does not receive the external force action, extension spring 4 can rebound and drive detection post 3 and reset. Preferably, the mounting section 331 is further provided with a grip 34, so that a technician can operate the detecting post 3 to lift and/or rotate through the grip 34. More preferably, the second measurer 32 is mounted on the mounting section 331.
