Abstract
The invention discloses a thread ring base ring hole tapping fixture of an engineering truck main speed reducer. The main speed reducer comprises a shell; a large plane is arranged on the shell; the tapping fixture comprises a base, 3-6 support plates and an opening ring; the upper and lower ends of the support plates are respectively in fixed connection with the base and the opening ring; and the inner diameter of the opening ring is between the outer diameter of the shell and the outer diameter of the large plane. The thread ring base ring hole tapping fixture of the engineering truck main speed reducer is a special tapping fixture for the main speed reducer, and has the advantages of simple structure, convenience for operation and high machining precision and finished product pass percent.
Description
Technical field
The present invention relates to a kind of frock clamp, be specifically related to a kind of engineering truck main reducing gear threaded collar seat ring hole tapping clamp.
Background technology
Main reducing gear reduces rotating speed in automotive transmission, utilizes Bevel Gear Transmission to change power direction and to increase the critical piece of moment of torsion.Wherein, main reducing gear is made up of differential assembly, speed reducer assembly (active and passive gear), main reducing gear housing assy etc., and main reducing gear housing assy is the installation foundation of differential assembly and speed reducer assembly.Must ensure in main reducing gear that driving and driven gear has good engagement situation, them just can be made well to work.The correct engagement of main reducing gear middle gear, except relevant with the crudy of gear, equipment adjustment and bearing, also has close relationship with the rigidity of main reducing gear housing assy and machining accuracy.In order to the needs assembled, main reducing gear housing assy is made up of final drive casing and pair of bearings lid and related fittings usually.
Final drive casing and bearing cap utilize bolt to be connected, and two end axles bearing is provided with the screwed hole that internal diameter is d, and screwed hole utilizes tapping machine to process, as shown in Figure 1.This tapping procedures need use Special tooling clamp, to improve machining accuracy, process velocity and product qualified rate.
Summary of the invention
The object of the invention is to provide that a kind of structure is simple, easy to operate, machining accuracy and product qualified rate is high, the engineering truck main reducing gear threaded collar seat ring hole tapping clamp of enhancing productivity.
For achieving the above object, the technical solution used in the present invention is: a kind of engineering truck main reducing gear threaded collar seat ring hole tapping clamp, described main reducing gear comprises housing, this housing is provided with large plane, described tapping clamp comprises base, 3 ~ 6 gripper shoes and opening annulus, the upper and lower end of described gripper shoe is fixedly connected with opening annulus respectively at described base, and the internal diameter of described opening annulus is between the external diameter and the external diameter of large plane of described housing.
Preferably, described base is connected by 3 described gripper shoes with opening annulus.
In technique scheme, described base is cirque structure.
Further technical scheme, 3 described gripper shoes are along a circumference uniform distribution.
Utilize the threaded collar seat ring hole of the present invention to main reducing gear to carry out tapping to comprise the steps:
(1) workseat is located on tapping clamp, and the large planar support of workpiece is on opening annulus;
(2) utilize the two end axles bearing of self-made tapping machine to main reducing gear to carry out tapping, ensure the tooth number of screwed hole, large footpath and central diameter;
(3) take off on the workpiece thread tapping fixture after processing, complete the tapping of the two end axles bearing screwed hole of main reducing gear.
Because technique scheme is used, the advantage that the present invention compared with prior art has is:
1. the present invention is the special tapping clamp of main reducing gear, structure is simple, easy to operate, machining accuracy and product qualified rate high.
Accompanying drawing explanation
Fig. 1 is the structural representation of main reducing gear in background technology of the present invention;
Fig. 2 is the front view of the embodiment of the present invention one;
Fig. 3 is the top view of embodiment one;
Wherein: 1, base; 2, gripper shoe; 3, opening annulus.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one: shown in Fig. 2, Fig. 3, a kind of engineering truck main reducing gear threaded collar seat ring hole tapping clamp, described main reducing gear comprises housing, this housing is provided with large plane, described tapping clamp comprises base 1,3 gripper shoes 2 and opening annulus 3, the upper and lower end of described gripper shoe 2 is fixedly connected with opening annulus 3 respectively at described base 1, and the internal diameter of described opening annulus 3 is between the external diameter and the external diameter of large plane of described housing.
In the present embodiment, described base 1 is cirque structure.3 described gripper shoes 2 are along a circumference uniform distribution.
Utilize the threaded collar seat ring hole of the present embodiment a pair main reducing gear to carry out tapping to comprise the steps:
(1) workseat is located on tapping clamp, and the large planar support of workpiece is on opening annulus;
(2) utilize the two end axles bearing of self-made tapping machine to main reducing gear to carry out tapping, ensure the tooth number of screwed hole, large footpath and central diameter;
(3) take off on the workpiece thread tapping fixture after processing, complete the tapping of the two end axles bearing screwed hole of main reducing gear.
The present invention is the special tapping clamp of main reducing gear, structure is simple, easy to operate, machining accuracy and product qualified rate high.
The above is the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from principle of the present invention; can also make some improvement or replacement, these improve or replace and also should be considered as protection scope of the present invention.
