The existing measuring tool can only be suitable for detecting the circular runout of the tooth surface of the cylindrical spur gear. Therefore, a detection tool suitable for circular runout of the tooth surface of the worm wheel needs to be designed.
SUMMERY OF THE UTILITY MODEL
The utility model discloses a solve not enough that above-mentioned background art exists, design the worm wheel flank of tooth circle and beat and detect the frock, this detects the minimum that can be accurate find worm wheel pitch circle circular arc tooth's socket, and then carries out the circle to this position and beats and detect, has finally guaranteed measurement accuracy.
In order to realize the technical characteristics, the purpose of the utility model is realized as follows: the worm gear tooth surface circle run-out detection tool comprises a deflection instrument, sliding tables which are symmetrically arranged are matched on a sliding rail at the top of the deflection instrument in a sliding mode, a thimble is mounted on each sliding table, the tail end of each thimble is provided with a tip, a mandrel is supported between the tips, and a worm gear to be detected is mounted on the mandrel in a matching mode; a steel ball capable of freely rolling is placed at the position of a pitch circle arc groove of the worm wheel, a dial indicator for detection is arranged right above the static position of the steel ball, and the dial indicator is installed on the deflection instrument through a support structure.
And center holes matched with the center points are processed in the center positions of the two ends of the mandrel.
The thimble passes through the mounting hole of handle locking at the slip table.
The diameter size of the steel ball ensures that the steel ball can be tangent to the inner wall of the pitch circular arc groove and can roll in the pitch circular arc groove.
The support structure comprises a magnetic base, the magnetic base is connected with the deflection instrument through magnetic force, a vertical rod is fixed at the top of the magnetic base, a horizontal rod is installed on the vertical rod, and a dial indicator is installed on the horizontal rod.
The utility model discloses there is following beneficial effect:
through adopting the utility model discloses a detection frock owing to only at the minimum of worm wheel pitch circle circular arc tooth's socket, the circle that could the accurate measurement worm wheel is beated, consequently, measures through the tangent steel ball of adopting a diameter and worm wheel pitch circle, because the steel ball dead weight, can find the minimum on the worm wheel pitch circle arc surface by oneself, consequently, comes the beat of auxiliary measurement worm wheel flank of tooth with the steel ball, can guarantee the detection quality that worm wheel flank of tooth circle is beated.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a front view of the present invention.
In the figure: the device comprises a deflection instrument 1, a slide rail 2, a sliding table 3, a handle 4, a thimble 5, a mandrel 6, a worm wheel 7, a dial indicator 8, a horizontal rod 9, a steel ball 10, a vertical rod 11, a tip 12, a magnetic base 13 and a pitch circle arc groove 14.
Detailed Description
The following describes embodiments of the present invention with reference to the accompanying drawings.
Referring to fig. 1, the worm gear tooth surface circle run-out detection tool comprises a deflection instrument 1, sliding tables 3 which are symmetrically arranged are arranged on a sliding rail 2 at the top of the deflection instrument 1 in a sliding fit mode, an ejector pin 5 is installed on each sliding table 3, the tail end of each ejector pin 5 is provided with an apex 12, a mandrel 6 is supported between the apexes 12, and a worm gear 7 to be detected is installed on the mandrel 6 in a matched mode; the steel ball 10 capable of freely rolling is placed at the position of the pitch circle arc groove 14 of the worm wheel 7, the dial indicator 8 for detection is arranged right above the static position of the steel ball 10, and the dial indicator 8 is installed on the yaw meter 1 through a support structure. Through adopting the detection frock of above-mentioned structure, can be used for the flank of tooth circle of worm wheel 7 to beat and detect, it can utilize the steel ball dead weight, can find the minimum on the worm wheel pitch circle arc surface by oneself, consequently, comes the run-out of auxiliary measurement worm wheel flank of tooth with the steel ball, can guarantee the detection quality that the flank of tooth circle of worm wheel beats.
Further, a central hole for matching with the tip 12 is processed at the central position of the two ends of the mandrel 6. The central hole can ensure that the mandrel 6 can be accurately positioned and installed.
Further, the thimble 5 is locked in the mounting hole of the sliding table 3 through the handle 4. The mandrel 6 can be positioned by the thimble 5, and smooth rotation in the subsequent detection process can be ensured.
Further, the diameter of the steel ball 10 is ensured to be tangent to the inner wall of the pitch circular arc groove 14, and the steel ball can roll in the pitch circular arc groove 14.
