The worm gear pair manufacturing precision comprehensive detection tool consists of a tool base 1, a worm positioning assembly 2, a worm positioning assembly 3, a measurement dial indicator and the like.
The tool base 1 is fixed on a working table. The top surface of the tool base 1 is a horizontal plane.
The worm positioning mechanism comprises a first fixed support 11, a second fixed support 12, a first rolling bearing 13, a second rolling bearing 14, a first center 15, a second center 16 and the like. The first fixing support 11 and the second fixing support 12 are arranged on the top surface of the tool base 1. The first fixed support 11 is opposite to the second fixed support 12 from left to right. The first rolling bearing 13 is arranged on the first stationary support 11. The second rolling bearing 14 is arranged on the second stationary support 12. Wherein, the first rolling bearing 13 and the second rolling bearing 14 can both adopt deep groove ball bearings. The first center 15 is fixed to the inner ring of the first rolling bearing 13. The second center 16 is fixed to the inner ring of the second rolling bearing 14. The worm to be measured is arranged between the first center 15 and the second center 16. The first tip 15, the second tip 16 and the worm to be measured have a common axis extending in the left-right direction. The first tip 15 and the second tip 16 jointly support the worm to be tested, namely the first tip 15 is arranged on the first end face of the worm to be tested, and the second tip 16 is arranged on the second end face of the worm to be tested. The worm to be tested is provided with a driven gear 17.
Preferably, the position of the first rolling bearing 13 is fixed and the position of the second rolling bearing 14 is adjustable. Specifically, the outer ring of the first rolling bearing 14 is directly fixed to the first fixed mount 11. The second rolling bearing 14 corresponds to a movable intermediate seat 110. The outer ring of the second rolling bearing 14 is directly fixed to the movable intermediate seat 110. The movable intermediate seat 110 has a screw section. The screw segments extend in a left-right direction. The movable middle seat 110 screw section extends into the second fixed support 12. The movable middle seat 110 screw section is mutually screwed with the second fixed support 12. The movable middle seat 110 is rotated to drive the position of the second rolling bearing 14 to adjust leftwards or rightwards, so that the first rolling bearing and the second rolling bearing are pre-tightened by utilizing the screwing of the screw section of the movable middle seat 110, the axial play of the bearings can be eliminated, the rotation precision of the measured worm is higher, the first center 15 (or the second center 16) is matched with the end face of the measured worm more tightly, the axial position of the measured worm is limited, and the tight engagement of the measured worm and the worm wheel is ensured.
In other embodiments, the position of the first rolling bearing 13 is adjustable and the position of the second rolling bearing 14 is fixed; alternatively, the positions of the first rolling bearings 13 and the positions 14 of the second rolling bearings are fixed; further alternatively, the positions of the first rolling bearing 13 and the second rolling bearing 14 may be adjusted.
The first fixed support 11 is provided with a driving shaft 18. The driving rotation shaft 18 is parallel to the worm to be tested. The driving shaft 18 is rotatably and slidably engaged with the first fixed support 11. Preferably, a sliding bearing 111 is disposed between the first fixed support 11 and the driving shaft 18. The sliding bearing 111 has a journal and a bush. The driving shaft 18 passes through the journal and is displaceable in the left-right direction. A driving gear 19 corresponding to the driven gear 17 is disposed on the driving shaft 18. The driving gear 19 is selectively engaged with or disengaged from the driven gear 17 by moving the driving shaft 18. When the driving gear 19 moves to the driven gear, the driving gear and the driven gear are meshed, the driving rotating shaft 18 is rotated, and the driving rotating shaft 18 drives the worm to be tested to rotate through the driving gear 19 and the driven gear 17, namely, rotational power is provided for the worm. The driving shaft 18 can be rotated by a motor.
Preferably, the driving shaft 18 has a limit stop 112 thereon. The limit baffle 112 and the driving gear 19 are respectively disposed on the left and right sides of the first fixed support 11. If the limit stop 112 (the driving gear 17) abuts against the first fixed support 11, the driving shaft 18 stops moving right (left), so that the driving shaft 18 does not slip out of the first fixed support 11.
The worm wheel positioning mechanism has a third fixed support 21, a guide shaft 22, a slider assembly 25, a worm wheel spindle 24, and the like. The third fixing support 21 and the slide block assembly 25 are uniformly distributed on the top surface of the tool base 1. The third fixed support 21 is opposite to the slider assembly 25 in front-rear direction. The third fixing support 21 is fixed with the guide shaft 22. The guide shaft 22 extends in the front-rear direction. The slider assembly 25 has a lower slider 251 and an upper slider 252 disposed above the lower slider. The lower slider 251 and the upper slider 252 may be fixedly connected together by screws. The lower slider 251 is slidably connected to the guide shaft 22, and the lower slider 251 may slide back and forth along the guide shaft 22.
The worm gear spindle 24 is arranged above the slider assembly 25. The worm wheel core shaft extends in the up-down direction. The lower end of the worm wheel spindle 24 extends downward through the upper slider 252 to the inside of the lower slider 251. The lower end of the worm wheel mandrel 24 is matched with the shaft hole of the lower slider 251. Preferably, the lower end of the worm wheel mandrel 24 can adopt Morse taper, and the centering effect is good. The worm gear spindle 24 has a spindle shoulder. The mandrel shoulder is below the upper slider 252. The upper slider 252 presses down on the shoulder of the mandrel 24. The dimensional chain of the parts is controlled to ensure that the shoulders of the mandrel 24 are not compressed and are free to rotate.
The upper end of the worm wheel mandrel 24 is provided with the worm wheel to be tested. The worm wheel to be tested is horizontally arranged. The worm wheel to be tested is meshed with the worm to be tested.
The third fixing support 21 accommodates an adjusting nut 23 therein. The adjusting nut 23 is wrapped around the periphery (hollow sleeve) of the guide shaft 22. The third fixing support 21 and the adjusting nut 23 are mutually screwed. The adjusting nut 23 and the lower slider 251 have a compression spring 26. The compression spring 26 may be disposed around the periphery of the guide shaft 22. The compression spring 26 is always in a compressed state. Under the action of the elasticity of the compression spring 26, the tooth surfaces of the worm wheel to be tested and the worm to be tested are guaranteed to be in double-sided engagement in the engagement state, namely, the tooth surfaces of the two sides are in a close contact state, and zero backlash exists.
The distance between the adjusting nut 23 and the lower slider 251 can be changed by rotating the adjusting nut 23, so as to adjust the elastic force of the compression spring 23 on the lower slider 251, thereby adjusting the sensitivity of the micro-motion operation of the compression spring 23 on the lower slider 251.
The measuring dial indicator is arranged on the top surface of the tool base 1. The measuring dial indicator is fixedly connected with the tool base 1. The measurement dial gauge is used for sampling the micro movement of the lower slider 251. The measuring dial gauge has a measuring rod parallel to the guide shaft 22. The end of the measuring rod is propped against the lower slider 251 back and forth. The fluctuation of the center distance between the worm wheel to be measured and the worm to be measured in a rotation range is reflected in the fluctuation of the measurement dial indicator through the micro-motion of the lower slider 251.
Working principle analysis: the rotation of the worm to be tested drives the rotation of the worm wheel to be tested, the worm to be tested rotates one circle and the worm wheel to be tested rotates one tooth, and the worm wheel and the worm are meshed under the condition of double-sided zero side clearance due to the elastic force of the compression spring 23 in the meshing process. Because the manufacturing tolerance will cause the center distance of the worm gear and the worm to be in continuous micro-motion change when the worm gear and the worm are meshed, the lower slider 251 is in continuous micro-motion movement, the micro-motion movement of the lower slider 251 will cause the continuous change of the reading of the measuring dial indicator, and the jump quantity of the measuring dial indicator is the comprehensive manufacturing tolerance of the worm gear and the worm gear when the two sides are meshed.
If the jump value measured by the measuring dial indicator exceeds a preset range, the machining error of the worm gear is excessive, and warehousing acceptance and product assembly cannot be carried out. Once assembled, the problems of engagement jamming, serious heating, overlarge noise, transmission error, low efficiency and the like are very likely to be caused.
The beneficial effects of this embodiment are: expensive detection equipment is saved in the early stage of product development; the detection of the small-module worm and gear can be realized by flexible change of the center distance, and the blank of detection equipment in the field of the small-module worm and gear is made up; the worm gear and worm is selected before the product is assembled, the current detection equipment is used for detecting single worm gear and worm, sometimes the precision detection of the single worm gear and worm is qualified, various noise temperature rise efficiency problems can occur after the assembly, and the like.
While only embodiments of the invention have been shown and described in detail, it is not intended that the scope of the invention be limited thereby. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention. Accordingly, the scope of protection of the present invention is to be determined by the appended claims.
