Abstract

The utility model relates to a hole aligning device for hole drilling of a hydraulic type supporting seat. The device comprises a support, a hole aligning clamp, two hydraulic cylinders, two couplers, two drills, a control switch and a hydraulic pump station, wherein the support is a telescopic support, the hole aligning clamp is fixed above the support and is divided into an upper end face and a lower end face, and two through holes are symmetrically formed in the lower end face along the central axis of the hole aligning clamp; the two hydraulic cylinders are located over the two through holes in the lower end face of the hole aligning clamp respectively, one ends of the two hydraulic cylinders are connected with the upper end face of the hole aligning clamp through bolts, and the other ends of the two hydraulic cylinders are connected with the drills through couplers; the control switch is located on the side wall of the hole aligning clamp; the hydraulic pump station is located on the left of the support and provides power for the whole device. The hole aligning device for hole drilling of the hydraulic type supporting seat has the advantages of being simple in structure, convenient to operate, low in manufacturing cost and the like, and the hole drilling position of the supporting seat can be determined fast.

Description

A kind of fluid pressure type props up seat for drilling to aperture apparatus

Technical field

The utility model relates to field of machining, and a kind of fluid pressure type props up seat for drilling to aperture apparatus specifically.

Background technology

Along with coal-mining developing rapidly in recent years, it is also driving the emergence of this industry of mining machinery, mining machinery has very important status in coal mining, bearing is modal in mining machinery, the installation of a lot of mining machineries all be unable to do without it, for the bearing processing, all use drilling machine to get out through hole on its hanger, in this process, all generally manually bearing to be fixed on to drilling machine below, then by the mode of line, determine the center of circle of boring, with drill bit, aim at the center of circle again, by hand hammer, beat drill bit, on bearing hanger, mark, finally with drilling machine, hole, this mode not only wastes time and energy, and the larger deviation of existence.Therefore, existing in the urgent need to a kind of simple in structure, easy to operate and can determine fast the instrument of bearing bore position, a kind of fluid pressure type props up seat for drilling to aperture apparatus.

Summary of the invention

In order to make up the deficiencies in the prior art, the utility model provides a kind of fluid pressure type to prop up seat for drilling to aperture apparatus.

The utility model solves the technical scheme that its technical problem adopts: a kind of fluid pressure type props up seat for drilling to aperture apparatus, comprise support, to hole fixture, two hydraulic cylinders, two shaft couplings, two drill bits, gauge tap and hydraulic power units, described support is telescope support, for regulating the height to hole fixture; Described is fixed on support top to hole fixture, and hole fixture is divided into upper surface and lower surface, and the central axis of Yan Dui hole, lower surface fixture is symmetrically arranged with respectively two through holes; Two described hydraulic cylinders lay respectively at directly over two through holes in fixture lower surface, hole, and by bolt, are connected between the upper surface of Yu Dui hole, two hydraulic cylinder one end fixture, between its other end and drill bit, by shaft coupling, are connected; Described gauge tap is positioned on the sidewall of hole fixture, and gauge tap is used for controlling startup of the present utility model, regulates and cuts out; Described hydraulic power unit is positioned at the left of support, by hydraulic power unit, provides power for whole device.

The beneficial effects of the utility model are: a kind of fluid pressure type props up seat for drilling aperture apparatus is had to the features such as simple in structure, easy to operate and cost of manufacture is low, and it can realize the function of determining fast bearing bore position.

The specific embodiment

As shown in Figure 1, Figure 2 and Figure 3, a kind of fluid pressure type described in the utility model props up seat for drilling to aperture apparatus, comprise support 1, to hole fixture 2, two hydraulic cylinders 3, two shaft couplings 4, two drill bits 5, gauge tap 6 and hydraulic power units 7, described support 1 is telescope support, for regulating the height to hole fixture 2; Described is fixed on support 1 top to hole fixture 2, and hole fixture 2 is divided into upper surface and lower surface, and the central axis of Yan Dui hole, lower surface fixture 2 is symmetrically arranged with respectively two through holes; Two described hydraulic cylinders 3 lay respectively at directly over hole fixture 2 two through holes in lower surface, and by bolt, are connected between the upper surface of two hydraulic cylinder 3 Yu Dui hole, one end fixtures 2, between its other end and drill bit 5, by shaft coupling 4, are connected; Described gauge tap 6 is positioned on the sidewall of hole fixture 2, and gauge tap 6 is for controlling startup of the present utility model, regulate and cutting out; Described hydraulic power unit 7 is positioned at the left of support 1, by hydraulic power unit 7, provides power for whole device.

During work, first manually by two hangers in two through holes difference alignment pieces 999 on hole fixture 2 lower surfaces, by regulating support 1 that lower surface is contacted with workpiece 999 surfaces, then by gauge tap 6, control the synchronous outwards stretching, extension of two hydraulic cylinders 3, when drill bit 5 lower ends contact with workpiece 999 surfaces, the suitable spread length of regulator solution cylinder pressure 3 again, workpiece 999 leaves certain vestige with drill bit 5 lower ends by extruding, this vestige is exactly the position that workpiece 999 needs boring, finally by gauge tap 6, controlling two hydraulic cylinders 3 synchronously shrinks inwards, finally reach the object of determining fast bearing bore position.

More than show and described basic principle of the present utility model, principal character and advantage.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; description in above-described embodiment and description principle of the present utility model is just described; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
