Description
Technical Field
The utility model relates to a concentricity detects the instrument, especially relates to an utensil is examined to reduction gear shell bearing hole concentricity.
Background
The reduction gear serves to match the rotational speed and the torque transmission between the prime mover and the working machine or the actuator, and is used in modern machines in a very wide range of applications. The speed reducer can be divided into two categories of a general speed reducer and a special speed reducer according to purposes, and the design, the manufacture and the use characteristics of the general speed reducer and the special speed reducer are different.
As shown in the attached drawing 1, the existing speed reducer casing 1 is provided with an inner bearing hole 2 and an outer bearing hole 3, the concentricity of the inner bearing hole and the outer bearing hole is required to be kept within a rated error range by standard requirements, so that the concentricity of the inner bearing hole and the outer bearing hole needs to be detected, the existing detection tool without the concentricity of the inner bearing hole and the outer bearing hole of the special speed reducer casing needs to separately detect and calculate, and the detection process is complicated and inconvenient.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the utility model designs an utensil is examined to reduction gear shell bearing hole concentricity.
The utility model adopts the following technical scheme:
the utility model provides an utensil is examined to reduction gear shell bearing hole concentricity, the on-line screen storage device comprises a base, fixedly connected with circle inscription workstation on the base, the central point of circle inscription workstation puts and is provided with the logical groove that runs through circle inscription workstation and base, the logical inslot at the center of circle inscription workstation articulates there is the stick-up pole, stick-up pole both ends are worn out logical groove, and swing along circle inscription workstation center pin joint, fixedly connected with support frame on the circle inscription workstation, be connected with the amesdial on the support frame, the probe of amesdial passes the support frame and supports and lean on stick-up pole one end, stick-up pole other end fixedly connected with touching probe, fixedly connected with spring leaf that resets on the circle.
Preferably, the support frame is fixedly connected with a fastening spring piece, and the fastening spring piece is tilted outside the circular inscribed workbench.
Preferably, the touch probe is in threaded connection with the tilting rod.
Preferably, the return spring piece and the fastening spring piece are fixed by a bolt.
Preferably, the cross section of the circular inscribed worktable is a circular inscribed polygon.
The utility model has the advantages that: this reduction gear shell bearing hole concentricity examines circle inscription workstation location reduction gear shell outer bearing hole of utensil, through the touching probe contact reduction gear shell inner bearing hole of perk pole bottom end portion, it is vertical when perk pole upper end, perk pole only contact do not have the pressure amesdial probe, amesdial probe data is zero, and reduction gear shell inner bearing hole and outer bearing hole are the concentric state of no deviation this moment. The concentricity of the inner bearing hole and the outer bearing hole of the reducer shell is conveniently and quickly detected by the concentricity detection tool for the bearing hole of the reducer shell.
Drawings
FIG. 1 is a schematic diagram of a conventional reduction housing;
fig. 2 is a schematic structural view of the present invention;
in the figure: 1. the speed reducer comprises a speed reducer shell, 2, an inner bearing hole, 3, an outer bearing hole, 4, a base, 5, a circular inner connecting workbench, 6, a tilting rod, 7, a dial indicator, 8, a touch probe, 9, a reset spring piece, 10, a fastening spring piece, 11 and a support frame.
Detailed Description
The technical solution of the present invention is further described in detail by the following specific embodiments in combination with the accompanying drawings:
example (b): as shown in the accompanying drawing 2, an utensil is examined to reduction gear housing bearing hole concentricity, including base 4, fixedly connected with circle inscription workstation 5 on the base, the central point of circle inscription workstation puts and is provided with the logical groove that runs through circle inscription workstation and base, the logical inslot at the center of circle inscription workstation articulates there is stick-up pole 6, stick-up pole both ends are worn out logical groove, and swing along circle inscription workstation center pin joint, fixedly connected with support frame 11 on the circle inscription workstation, be connected with amesdial 7 on the support frame, the probe of amesdial passes the support frame and supports and lean on stick-up pole one end, stick-up pole other end fixedly connected with touches probe 8, fixedly connected with spring piece 9 that resets on the circle inscription workstation, the spring piece that resets. The support frame is fixedly connected with a fastening spring piece 10, and the fastening spring piece is tilted outside the circular inscribed workbench. The touch probe is in threaded connection with the tilting rod. The reset spring piece and the fastening spring piece are fixed through bolts. The cross section of the circular inscribed workbench is a circular inscribed polygon.
When the concentricity testing fixture for the bearing hole of the speed reducer shell is used, the circular inscribed workbench is positioned in the bearing hole outside the speed reducer shell, the spring leaf is fastened, the touch probe is contacted with the inner edge of the bearing hole inside the speed reducer shell, then the data of the dial indicator is checked, the concentricity rated error range is compared, and the concentricity of the bearing hole inside and outside the speed reducer shell is conveniently and quickly tested by the concentricity testing fixture for the bearing hole of the speed reducer shell.
The above-described embodiments are only preferred embodiments of the present invention, and are not intended to limit the present invention in any way, and other variations and modifications may be made without departing from the scope of the claims.
