Abstract
The utility model discloses a tapping clamp of a ring hole of a thread ring base of a main speed reducer of an engineering truck. The main speed reducer comprises a shell which is provided with a large plate. The tapping clamp comprises a base, 3-6 supporting plates and an open round ring, the upper end and the lower end of each supporting plate are connected with the base and the opening round ring respectively and fixedly, and the inner diameter of the opening round ring ranges between the outer diameter of the shell and the outer diameter of the large plane. The tapping clamp is specially used for the main speed reducer, and is simple in structure, convenient to operate and high in machining precision and qualified rate of finished products.
Description
Technical field
the utility model relates to a kind of frock clamp, is specifically related to a kind of engineering truck main reducing gear threaded collar seat ring hole tapping clamp.
Background technology
main reducing gear is to reduce rotating speed in automotive transmission, utilize Bevel Gear Transmission to change power direction and to increase the critical piece of moment of torsion.Wherein, main reducing gear is comprised of differential assembly, speed reducer assembly (master, driven gear), main reducing gear housing assy etc., and the main reducing gear housing assy is the installation basis of differential assembly and speed reducer assembly.Must guarantee in main reducing gear that driving and driven gear has good engagement situation, just can make their good work.The correct engagement of main reducing gear middle gear, except the crudy with gear, equipment adjustment and bearing are relevant, also have close relationship with rigidity and the machining accuracy of main reducing gear housing assy.For the needs that assemble, the main reducing gear housing assy usually by final drive casing and pair of bearings, is covered and related fittings forms.
final drive casing utilizes bolt to be connected with bearing cap, and the 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 be used Special tooling clamp, to improve machining accuracy, process velocity and product qualified rate.
Summary of the invention
the engineering truck main reducing gear threaded collar seat ring hole tapping clamp that the utility model purpose is to provide a kind of simple in structure, easy to operate, machining accuracy and product qualified rate is high, enhance productivity.
for achieving the above object, the technical solution adopted in the utility model 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 the opening annulus respectively at described base, and the internal diameter of described opening annulus is between the external diameter on the external diameter of described housing and large plane.
preferably, described base is connected by 3 described gripper shoes with the opening annulus.
in technique scheme, described base is cirque structure.
further technical scheme, 3 described gripper shoes are along a circumference uniform distribution.
utilizing the utility model to carry out tapping to the threaded collar seat ring hole of main reducing gear comprises the steps:
(1) workseat is located on tapping clamp, and the large planar support of workpiece is on the opening annulus;
(2) utilize the self-made tapping machine to carry out tapping to the two end axles bearing of main reducing gear, guarantee the tooth number of screwed hole, large footpath and central diameter;
(3) by taking 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 utility model compared with prior art has is:
1. the tapping clamp that the utility model is the main reducing gear special use, simple in structure, easy to operate, machining accuracy and product qualified rate are high.
The accompanying drawing explanation
fig. 1 is the structural representation of main reducing gear in the utility model background technology;
fig. 2 is the front view of the utility model embodiment mono-;
fig. 3 is the top view of embodiment mono-;
wherein: 1, base; 2, gripper shoe; 3, opening annulus.
The specific embodiment
below in conjunction with drawings and Examples, the utility model is further described:
embodiment mono-: 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 1,3 gripper shoes 2 of base 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 on the external diameter of described housing and large plane.
in the present embodiment, described base 1 is cirque structure.3 described gripper shoes 2 are along a circumference uniform distribution.
utilizing the threaded collar seat ring hole of a pair of main reducing gear of the present embodiment to carry out tapping comprises the steps:
(1) workseat is located on tapping clamp, and the large planar support of workpiece is on the opening annulus;
(2) utilize the self-made tapping machine to carry out tapping to the two end axles bearing of main reducing gear, guarantee the tooth number of screwed hole, large footpath and central diameter;
(3) by taking 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 tapping clamp that the utility model is the main reducing gear special use, simple in structure, easy to operate, machining accuracy and product qualified rate are high.
the above is preferred embodiment of the present utility model; should be understood that; for those skilled in the art; under the prerequisite that does not break away from principle described in the utility model; can also make some improvement or replacement, these improvement or replacement also should be considered as protection domain of the present utility model.
