Abstract
The utility model provides a multi-head drilling machine with an adjustable hole spacing. A power mechanism, a gear group and a drilling bit disc are arranged on a frame; a plurality of drilling bits are distributed into a circle on the drilling bit disc through drilling bit holders; power output by the power mechanism is distributed by the gear group and then transferred to each drilling bit respectively; a plurality of guide blocks are distributed on the inner wall of the drilling bit disc; clamping columns are arranged at the centre of the drilling bit disc; each drilling bit holder is arranged in a slide way composed of the guide blocks, adhered to the side surface of the clamping column, and tightly pulled by a puller bolt; and the drilling bits are connected with the gear group by a universal shaft coupler. In the multi-head drilling machine with an adjustable hole spacing disclosed by the utility model, a plurality of drilling bits are disposed, thus increasing efficiency; simultaneously, clamping columns are arranged among the drilling bits, and the spacing among the drilling bits is changed by using the clamping columns with different dimensions, so as to be adapted to steel pipe flanges with different specifications. The multi-head drilling machine with an adjustable hole spacing disclosed by the utility model is simple in structure, simple and convenient in replacement of components, and convenient in maintenance and repair.
Description
Technical field
The utility model relates to the drilling machine of field of machining, specifically a kind of multiple drill press of adjustable pitch.
Background technology
Steel pipe has in producing and living widely and uses as a kind of transport pipeline.Connection between the steel pipe all is provided with flange at the two ends of steel pipe often, on flange, holes then, couples together with the flange of bolt with two sections steel pipes again.In the prior art, the boring method of steel pipe upper flange is: steel pipe is placed on the platform two ends and draws corresponding line, two ends boring then.Also there is bull to bore on the market now; But the drill bit distance is all fixed, and the diameter of steel pipe has plurality of specifications, and its flange drilling position, two ends also changes diametrically; Therefore; The drilling machine that needs a few bench drill head distances of extra preparation not wait is prepared against and on the steel pipe flange of different-diameter, is holed, and has improved production cost, has reduced production efficiency.
The utility model content
Be the problem that the distance that solves between the existing multiple drill press drill bit can't change, the utility model provides a kind of multiple drill press of adjustable pitch.
The utility model is that the technical scheme that solves the problems of the technologies described above employing is: a kind of multiple drill press of adjustable pitch, frame are provided with actuating unit, gear train and drill bit dish, and a plurality of drill headstocks are rounded to be distributed on the drill bit dish; Drill bit is arranged in the drill headstock, and the power of actuating unit output is passed to each drill bit respectively after distributing through gear train, and the drill bit dish is hollow circular ring structure; On the inwall of drill bit dish, be distributed with a plurality of guide pads; Each drill headstock all is arranged in the slideway that is made up of guide pad, is provided with the card post at the center of drill bit dish, and the card post is a regular prism shape; Its rib number equates with the quantity of drill headstock; And each side of card post all fits with a drill headstock, on the excircle of drill bit dish, is provided with and the corresponding puller bolt of drill headstock, and drill bit is connected with gear train through Hooks coupling universal coupling.
In the utility model, the size of card post can be according to the size change of institute's drill steel pipe flange, and drill bit moves in the slideway that guide pad forms, and puller bolt also changes thereupon simultaneously.
Beneficial effect: be provided with a plurality of drill bits in the utility model, improved efficient; Simultaneously, be provided with the card post between the drill bit, change the spacing between the drill bit through the card post that uses different size, to adapt to the steel pipe flange of different size.The utility model is simple in structure, and part exchanging is easy, is convenient to maintenance and repair.

The specific embodiment
As shown in the figure, a kind of multiple drill press of adjustable pitch, frame 1 is provided with actuating unit 2, gear train 3 and drill bit dish 9; A plurality of drill headstock 6 rounded being distributed on the drill bit dish 9, drill bit 7 is arranged in the drill headstock 6, and the power of actuating unit 2 outputs is passed to each drill bit 7 respectively after distributing through gear train 3; Drill bit dish 9 is hollow circular ring structure, on the inwall of drill bit dish 9, is distributed with a plurality of guide pads 5, and each drill headstock 6 all is arranged in the slideway that is made up of guide pad 5; Be provided with card post 8 at the center of drill bit dish 9; Card post 8 is a regular prism shape, and its rib number equates with the quantity of drill headstock 6, and each side of card post 8 all fits with a drill headstock 6; On the excircle of drill bit dish 9, be provided with and drill headstock 6 corresponding puller bolts 10, drill bit 7 is connected with gear train 3 through Hooks coupling universal coupling 4.
When the vary in diameter of institute's drill steel pipe upper flange; Respectively the puller bolt 10 of drill bit 7 is turned on; Take out card post 8 then, the card post 8 after will changing again is fixed on the center of drill bit dish 9, turns puller bolt 10 then respectively and makes drill bit 7 hold out against with card post 8 corresponding sides.
