Abstract

The utility model discloses a holding fixture for drilling an inclined hole on one end enclosure. The utility model is characterized in that two vertical bracing plates is fixedly connected to a base (1) provided with a connecting trough (2), wherein, the upper end face of each of the vertical bracing plates is a cambered surface, and the base (1) provided with the connecting trough (2) is arranged on the center of an edge of the utility model; one oblique fixing and connecting post (7) is fixed on the center of the base (1). The utility model is connected and fixed with a worktable along a lathe, an end enclosure is fixed on the utility model again, one or more oblique holes can be drilled on the end enclosure by a drilling tool, and oblique holes on different circumferences can also be drilled; during the operation of the utility model, safety performance is favorable, process steps are less, operation is simple, work efficiency is raised by eight to ten times, and process quality in drilling holes is guaranteed or raised.

Description

Bore the anchor clamps of end socket inclined hole

The utility model relates to a kind of anchor clamps, is specially a kind of anchor clamps that bore the end socket inclined hole.

Rat holing on the half elliptic that top or bottom had of metal can or semicircular end socket, now employed is radial drilling machine.When radial drilling machine bores the end socket inclined hole, need be provided with above or below end socket and reinforce object and reinforce, end socket is stressed easily impaired and cave in, and end socket easily rocks, and drill bit is fragile, and inclined to one side hole phenomenon occurs boring, and the up-to-standard degree of processing is low, has only 10-30%; Manufacturing procedure is many, takes manpower, and when taking a lot of work, efficient is low.

The purpose of this utility model provides a kind of anchor clamps that bore the envelope inclined hole, utilizes these anchor clamps to use drilling machine to bore the end socket inclined hole, end socket can be fastened on the anchor clamps, and end socket is not damaged and depression do not occur, and the end socket fixation has guaranteed the quality of processing, and has improved efficient.

To achieve these goals, the utility model is to have on the base of link slot, is fixedly connected with two vertical support plates, and a fixedly connected post that tilts is fixed in the center of base.

Below in conjunction with accompanying drawing and with embodiment the utility model is done to be described in detail:

Accompanying drawing is a structural representation of the present utility model

Can find out from accompanying drawing, the utility model is to have on the base 1 of link slot 2 in the center at its edge, being fixedly connected with the upper surface is two vertical support plates 3 of arcwall face, the center of base 1 is fixed with that tilt, the screwed fixedly connected post 7 in upper end, on the fixedly connected post 7 have thread segment below have backstop 6, be equipped with nut 4 on the thread segment of fixedly connected post 7, between nut 4 and backstop 6, be equipped with locating pad 5 on the fixedly connected post 7.

When using these anchor clamps to bore the inclined hole of end socket, the workbench of these anchor clamps by link slot on it and drilling machine is connected to a fixed, then nut and locating pad are taken off, end socket is covered on the anchor clamps, and the centre bore of end socket is inserted in the upper end that makes it joint pin, put locating pad again and the nut of screwing on, end socket is fixed on the anchor clamps, and the position that makes it the inclined hole that will bore places between two vertical support plates, again with the edge of drill bit near locating pad, drilling machine is started at the center that aligning will be holed, and just can get out inclined hole on end socket; Use these anchor clamps can not only bore an inclined hole, any position on same circumference and any angle use same locating pad all can hole; As boring a plurality of inclined holes on the end socket, on locating pad, to draw earlier good angle line; If a plurality of inclined holes not on same circumference, just need a plurality of locating pads, or rule, adjust the angle of base plate simultaneously on end socket.

Use anchor clamps of the present utility model, end socket can be fixed securely, end socket firm stable during boring, drill bit is not fragile, and end socket is unlikely and flies away from away, and the security during operation is good; Operation is few during boring, and is easy to operate, alleviated labour intensity, and time saving and energy saving saving of labor raises the efficiency 8-10 doubly; Be not prone to end socket depression problem, be not prone to and bore inclined to one side hole problem, guarantee or improved the crudy of boring.It not only is suitable for using on drilling machine, also is suitable for using on lathe, boring machine, milling machine and grinding machine, not only is used for rat holing, also can be used for processing hole, groove, face of other form etc.

Claims

1, a kind of anchor clamps that bore the end socket inclined hole, it is characterized in that: it is to have on the base (1) of link slot (2) in the center at its edge, being fixedly connected with the upper surface is two vertical support plates (3) of arcwall face, the center of base (1) is fixed with that tilt, the screwed fixedly connected post in upper end (7), fixedly connected post (7) go up have thread segment below have backstop (6), be equipped with nut (4) on the thread segment of fixedly connected post (7), go up at fixedly connected post (7) and between nut (4) and backstop (6), be equipped with locating pad (5).
