Abstract
The utility model discloses a cylinder cover auxiliary bolt hole drilling jig for remanufacturing a diesel engine cylinder block, which comprises a drilling template. The drilling template is provided with a cylinder cover auxiliary bolt hole drilling bushing, a round hole-shaped positioning bushing, and a diamond positioning bushing, wherein the round hole-shaped positioning bushing corresponds to the cylindrical positioning pin on a cylinder block; and the diamond positioning bushing corresponds to a round stop pin additionally arranged on the cylinder block. by designing the positioning bushings and the drill bushing on the template, the dismounting of an original cylinder cover auxiliary bolt and the positioning pin is avoided, and the traditional positioning mode with two bolts on one surface is changed, the positioning pin is improved into a pin bushing for positioning, which favorably meets the positioning requirements and achieves accurate positioning and convenient and reliable clamping.
Description
Technical field
The utility model relates to a kind of drill jig of making the secondary bolt hole of diesel engine cylinder cover again.
Background technology
After market was returned machine and disassembled, that many cylinder block have was single, two rows or do not have the secondary bolt hole of cylinder cap, if continue to make engine again with this state assembling, did not satisfy and made the engine performance requirement of installing again, can cause many hidden danger of quality.
The utility model content
Technical problem to be solved in the utility model provides a kind of location, the reliable cylinder of diesel engine of convenient mounting and clamping is made with the secondary bolt hole drill jig of cylinder cap again.
For solving the problems of the technologies described above, the technical solution of the utility model is: cylinder of diesel engine is made with the secondary bolt hole drill jig of cylinder cap again, comprises bushing plate, and the secondary bolt hole drill bushing of cylinder cap is installed on the described bushing plate; The circle hole shape positioning sleeve also is installed on the described bushing plate, and described circle hole shape positioning sleeve is corresponding with the cylinder alignment pin on the described cylinder block; The rhombus positioning sleeve also is installed on the described bushing plate, and described rhombus positioning sleeve is corresponding with the other circular alignment pin on the described cylinder block.
As optimized technical scheme, also be provided with gripper shoe under the described bushing plate.
Owing to adopted technique scheme, cylinder of diesel engine to make again with the secondary bolt hole drill jig of cylinder cap, comprise bushing plate, the secondary bolt hole drill bushing of cylinder cap is installed on the described bushing plate; The circle hole shape positioning sleeve also is installed on the described bushing plate, and described circle hole shape positioning sleeve is corresponding with the cylinder alignment pin on the described cylinder block; The rhombus positioning sleeve also is installed on the described bushing plate, and described rhombus positioning sleeve is corresponding with the other circular alignment pin on the described cylinder block; Design has positioning sleeve and drill bushing on the bushing plate, avoided dismounting to secondary bolt of original cylinder cap and alignment pin, change traditional plane and two pits locate mode, alignment pin is improved the mode become the guide location well satisfied positioning requirements, accurate positioning, convenient mounting and clamping are reliable.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the upward view of Fig. 1;
Fig. 3 is the vertical view of Fig. 1.
The specific embodiment
As Fig. 1, Fig. 2 and shown in Figure 3, cylinder of diesel engine is made with the secondary bolt hole drill jig of cylinder cap again, comprises bushing plate 1, and the secondary bolt hole drill bushing 5 of cylinder cap is installed on the described bushing plate 1; On the described bushing plate 1 circle hole shape positioning sleeve 3 is installed also, described circle hole shape positioning sleeve 3 is corresponding with the cylinder alignment pin on the described cylinder block; Rhombus positioning sleeve 4 also is installed on the described bushing plate, and described rhombus positioning sleeve 4 is corresponding with the other circular alignment pin on the described cylinder block, and also designing under the described bushing plate has gripper shoe 2.
Design has circle hole shape positioning sleeve and rhombus positioning sleeve on the bushing plate, avoided dismounting to secondary bolt of original cylinder cap and alignment pin, change traditional plane and two pits locate mode, can satisfy the processing of finishing other secondary bolt hole under the situation of not tearing secondary bolt of original cylinder cap and alignment pin open, well satisfied positioning requirements, accurate positioning, convenient mounting and clamping are reliable.
