Description
Technical Field
The utility model relates to a sliding sleeve external splines and bearing excircle coaxiality short-term test device.
Background
The concentricity of an external spline of the sliding sleeve and the excircle of a bearing needs to be detected in a three-coordinate mode at present, the external spline in the whole circumferential direction of the sliding sleeve needs to be scanned by a probe, the scanning position is the tooth side, the external spline is detected one by one, then the excircle of the bearing is scanned, and finally whether the external spline is concentric or not can be obtained through complex calculation, the detection time of the detection method is shortest and is 30 minutes, the detection time is long, the detection efficiency is low, and the processing efficiency is influenced; and the burr of the spline of the sliding sleeve has a great influence on the scanning precision of the probe, and whether the probe scans the external spline and the bearing excircle are absolutely influenced by the experience of a scanning operator on the same circumference is great.
SUMMERY OF THE UTILITY MODEL
The utility model aims at solving the above-mentioned problem that exists among the prior art, provide a spline and the quick detection device of bearing circle axiality of sliding sleeve, it detects directly perceived, and check-out time is short, has shortened more than 6 times, and detection efficiency is high, and then has improved the machining efficiency of sliding sleeve.
In order to achieve the above object, the technical solution of the present invention is: a quick detection device for coaxiality of a spline of a sliding sleeve and a bearing circle comprises a bearing with an inner hole with taper, more than three same measuring rods, a fixing frame and a dial indicator or a dial indicator; the surface with the large diameter of the inner hole of the bearing is arranged below, the upper end of the fixing frame is fixed on the outer sleeve of the bearing through a screw, the lower end of the fixing frame is provided with a probe through hole of the dial indicator or the dial indicator, the probe penetrates through the probe through hole and is fixed in the probe through hole through a meter clamping sleeve, and the verticality of the central axis of the probe of the dial indicator or the dial indicator and the central axis of the bearing taper hole is ensured; when the detection is carried out, the external spline of the detected sliding sleeve is arranged in the bearing inner sleeve through the measuring rods which are uniformly distributed, one end of each measuring rod is tightly attached to the tooth surface of the external spline of the detected sliding sleeve, and the other end of each measuring rod is tightly propped against the inner wall of the bearing inner sleeve.
Further preferably, the measuring rod is 3, and the mutual 120 contained angles that become distribute, both saved the use of measuring rod, can guarantee again to be surveyed the straightness that hangs down of the center pin of sliding sleeve, detect with low costs.
During detection, a detected sliding sleeve is arranged or fixed on an operation platform with excellent levelness, then the spline part of the detected sliding sleeve is arranged in a bearing inner sleeve of a detection device, a rotary bearing, a probe of a dial indicator or a dial indicator rotates on the bearing outer circle of the detected sliding sleeve, and the concentricity between a measurement reference and a detected optical axis can be read out through the change of a pointer of a gauge head of the dial indicator or the dial indicator. The utility model discloses an involute external spline stick needle centering technique uses three (also can be evenly distributed's more than three) stick needle to place in the spline flank, is 120 contained angles respectively, recycles the second class measuring tool and entangles the stick needle outside to reach the purpose at definite spline center. The utility model discloses still adopted the rotation measurement technique to the bearing inner circle is the benchmark, will measure the gauge outfit and fix on the bearing outer circle, and swivel bearing makes the measuring gauge rotatory on being surveyed the excircle, changes through measuring gauge outfit pointer, can read out the concentricity between measuring basis and the measured optical axis. The utility model discloses directly perceived of detection, check-out time shortens to 5 minutes, and check-out time is short, has shortened more than 6 times, and detection efficiency is high, detects with low costs, and efficiency has promoted more than 83%, and then has improved the machining efficiency of sliding sleeve, has improved the output, reduces the processing cost.

Detailed Description
The present invention will be further described with reference to the following embodiments.
As shown in fig. 1 and fig. 2, the present embodiment includes a bearing 9 with a tapered inner bore, three (four, five, etc. that may also be uniformly distributed) identical measuring rods 4, a fixing frame 7, and a dial indicator 6 (which may also be a dial indicator). The side with the large diameter of the inner hole of the bearing 9 is arranged at the lower part. The upper end of the fixing frame 7 is fixed on the outer sleeve 3 of the bearing 9 through a screw 8, the lower end of the fixing frame is provided with a probe through hole 12 of the dial indicator 6, the probe 11 penetrates through the probe through hole 12 and is fixed in the probe through hole 12 through the indicator jacket 5, and the perpendicularity of the central axis of the probe 11 of the dial indicator 6 and the central axis of the bearing taper hole is ensured. During detection, the external spline of the detected sliding sleeve 10 is arranged in the bearing inner sleeve through the measuring rods 4 which are uniformly distributed, one end of each measuring rod 4 is tightly attached to the tooth surface of the external spline of the detected sliding sleeve 10, and the other end of each measuring rod is tightly propped against the inner wall of the bearing 9 inner sleeve. Preferably, the measuring rods 4 are 3 and are distributed at an included angle of 120 degrees with each other. 1. 2 are all screws.
