Problems solved by technology

Since the strength of aluminum casting plugs is not as strong as that of cast iron or cast steel plugs, the plugs are easily bent under the pressure of the drill bit during drilling operations, which affects the flatness of the end faces of the plugs, resulting in poor sealing of the plugs, etc. defect
In the traditional technology, in order to prevent the drilling process from affecting the flatness of the end face of the plug, most of them add a grinding process after the drilling process is completed, which will cause a waste of production resources

Embodiment Construction

[0024] Below in conjunction with embodiment the present invention is described in further detail:

[0025] Such as Figure 1 to Figure 4 As shown, the present invention is a fixture used for the drilling process of the blocking cap 1, which includes a seat plate 2, a blocking cap clamping device and a positioning slider 10 for angularly positioning the blocking cap 1.

[0026] The four corner threads of the seat plate 2 are provided with four movable legs, and loosening nuts are also installed on the upper ends of the movable legs. The seat plate 2 is provided with drill bit 14 through holes, and a drill sleeve 13 is embedded in each through hole to guide and protect the drill bit 14 . The both sides of seat board 2 also are equipped with the handle that is convenient for worker's carrying. In actual use, the base plate 2 is placed on the rocker drill floor by using the legs, and then the drill bit 14 extends from the drill sleeve 13 to the bottom of the base plate 2 to dril...

Abstract

The invention discloses a plug cover drilling fixture, and belongs to the field of fixtures. The plug cover drilling fixture comprises a base plate provided with movable support legs at four corners; the base plate is provided with drill bit passing holes corresponding to plug cover hole positions; a plug cover clamping device is mounted below the base plate, and includes a plug cover limiting plate fixedly mounted below the base plate; the plug cover limiting plate is provided with an annular projection matched with a plug cover annular groove; the plug cover clamping device further includes a plug cover pressing plate capable of bonding with the whole surface of the back surface of a plug cover; and the plug cover pressing plate is also provided with drill bit passing holes corresponding to the plug cover hole positions. The novel plug cover drilling fixture can prevent deformation of the plug cover in the drilling process, guarantees no influence on flatness of the end surface of the plug cover, and improves the quality of the plug cover.

Description

technical field [0001] The invention relates to a clamp, in particular to a plugging drilling jig, which is used for clamping the plugging during the drilling process of the plugging. Background technique [0002] Such as Figure 4 As shown, the plugging parts are a kind of key components on the diesel engine, which are used to block various through holes on the diesel engine box, such as the assembly access holes on the flywheel housing, the inspection holes on the oil pan, etc. The blocking cover is usually provided with an end face used for matching with the engine block, which is formed by turning, and a circular ring groove is also arranged on the end face, which is also formed by turning, and the ring groove is usually used for installing a sealing ring. Bolt through holes are usually also arranged on the blocking cover, which is convenient for installing the blocking cover on the engine by using bolts. [0003] Because its role on the engine is mostly to block the bo...
