Problems solved by technology

However, there are two clampings in this method, so the grinding benchmark cannot be completely agreed, which greatly affects the final grinding accuracy
On the other hand, the method of directly clamping the steering gear shell by the claws will easily lead to deformation of the steering gear shell, which will eventually lead to scrapping and increase the production cost

Embodiment 1

[0036] Such as figure 1 , figure 2 As shown, a precision guidance steering gear casing grinding fixture includes: a mandrel 4 and a connecting block 5; the mandrel 4 passes through the connecting block 5, and the relative position of the connecting block 5 and the mandrel 4 along the circumference remains fixed, and the connecting block 5 can slide along the axis of the mandrel 4, but cannot rotate around the axis of the mandrel 4; the rear end of the mandrel 4 is used to connect the machine tool.

[0037] Such as Figure 6 , Figure 7 As shown, the housing of the steering gear clamped by the clamp of the present application includes a main housing 1 in a cylindrical structure and a base 2 arranged at the rear end of the main housing 1 . The inside of the main housing 1 is provided with a first seat hole 11, a second seat hole 12 and a through hole 13 sequentially from the back to the front. The front end of the through hole 13 has a conical hole 14. The inclined hole 15 ...

Embodiment 2

[0046] Such as figure 1 , image 3 As shown, the precision guidance steering gear housing grinding fixture also includes a limit block 6, which is arranged on the front end of the mandrel 4; when in use, the limit block 6 is located in the first seat hole 11, and the outer wall of the limit block 6 Fitting with the inner wall of the first seat hole 11, because the steering gear shell is a long tubular structure, away from the end clamped by the machine tool, the swing range is relatively large when rotating, which seriously affects the shape accuracy of the steering gear shell after grinding; the mandrel 4 passes through the limit The block 6 supports the rear end of the steering gear housing to improve the stability of the connection between the mandrel 4 and the steering gear housing, thereby reducing the swing range of the rear end of the steering gear housing and improving the processing quality.

specific Embodiment approach

[0051] Specific embodiments: when clamping, the mandrel 4 is inserted into the main housing 1 from one end of the through hole 13 , and the main housing 1 is connected and fixed to the mandrel 4 through the inclined hole 15 with screws. The connecting block 5 is loaded from the rear end of the main housing 1 so that the connecting block 5 is located at the mounting position of the cover plate 3 .

[0052] Install the cover plate 3, use the cover plate 3 to pre-fix the connecting block 5, install the positioning screw 7, fix the position between the connecting block 5 and the mandrel 4, then fully tighten the mounting screws of the cover plate 3, and use the cover plate 3 The connecting block 5 is finally fixed, so as to ensure the stability of the relative positions among the cover plate 3 , the mandrel 4 and the connecting block 5 , and also realize the second connection between the main casing 1 and the mandrel 4 .

[0053] Install the limiting block 6 , pull the limiting bl...

Abstract

The invention provides a precision guidance steering engine outer shell grinding clamp. The precision guidance steering engine outer shell grinding clamp comprises a mandrel and a connecting block; the mandrel penetrates through the connecting block, and the relative positions of the connecting block and the mandrel along the circumference are kept fixed; and the rear end of the mandrel is used for being connected with a machine tool. The front section of the mandrel penetrates into a main shell from the front end of the main shell of an steering engine; the connecting block is located in a second seat hole of the main shell, and the outer wall of the connecting block is attached to the inner wall of the second seat hole; a cone frustum is arranged at the position, corresponding to a conical hole of the main shell, of the mandrel, and the cone frustum is matched with the conical hole; and screws are arranged in inclined holes of the main shell in a penetrating manner and are used for being connected with the mandrel. A positioning screw rod is arranged on the periphery of the connecting block and penetrates through through holes formed in cover plates on the main shell. Overall grinding machining of a steering engine outer shell can be completed through one-time clamping, the grinding quality can be effectively improved, and the shape precision of the steering engine outer shell can be effectively guaranteed. Meanwhile, deformation of the steering engine outer shell can be avoided, the yield is improved, and therefore cost is reduced.

Description

technical field [0001] The invention belongs to the production and processing technology of a steering gear used in the field of precision guidance, and in particular relates to a grinding jig for a shell of a precision guidance steering gear. Background technique [0002] Steering gear is widely used in the field of precision guidance. Since precision guidance has strict requirements on guidance accuracy, flight stability and other aspects, the processing quality of the steering gear shell used for precision guidance is also very high. Such as Figure 6 , Figure 7 As shown, the steering gear housing mainly includes a main housing, a base, and multiple cover plates. In order to improve the overall processing quality of the outer wall of the steering gear housing, it is usually necessary to assemble the main housing, base, and cover plates for overall grinding. Since the overall casing of the steering gear has a tubular structure and is a thin-walled part, it is very inconv...
