Abstract
An integral boring machine for machining structural parts of a coal mine hydraulic support belongs to the field of mechanical manufacturing. The technical scheme includes that a power transmission device is fixed on a base through a thread pair and can be adjusted, a spindle of the power transmission device is connected with a boring bar spindle through double moving joints, the boring bar spindle is supported by four boring bar supports, two boring bar supports are fixed on the base, the other two boring bar supports are mounted on a fixed base, and a plurality of boring tools are mounted on the boring bar spindle and fastened via jackscrews. The integral boring machine for machining structural parts of the coal mine hydraulic support has the advantages that the boring bar spindle is connected with the power transmission device through the double moving joints so that the effect of vibration on the performance of the power transmission device during boring is lowered greatly, the integral boring machine for machining structural parts of the coal mine support such as a base, single (double) connecting bars, a top beam, a shield beam, a tail beam and a front beam can be used for machining holes of different hole pitches and diameters and can better guarantee coaxiality of multiple holes, assembly quality of the structural parts of the hydraulic support can be improved, and the integral boring machine is unique in design, reasonable in structure, simple in operation and easy in maintenance.
Description
Technical field
The utility model relates to a kind of whole boring machine of processing the colliery hydraulic support structural member, belongs to mechanical manufacturing field.
Background technology
Current, along with improving constantly of safety of coal mines, the use amount of middle and high end hydraulic support constantly increases, but the production occupied fund of hydraulic support structural member is bigger.In conjunction with the present reality of China; Numerous medium and small colliery hydraulic support manufacturer is not very strong to the purchasing power of equipment, can not break-through axle bore hole such as the processing difficult problem of base, back timber etc. and many assembly problems that produces owing to the hole decentraction to such an extent as in the process of production structure part, produced in the structural member.Press for a kind of simple in structure, good concentricity of development, boring machine that input cost is low.
Summary of the invention
The purpose of the utility model overcomes above defective exactly, develops the whole boring machine of a kind of simple in structure, good concentricity, processing colliery hydraulic support structural member that input cost is low.
The technical scheme of the utility model is: actuating unit is fixed on the base with screw thread pair and adjusts, and the main shaft of actuating unit is connected by the dual-active joint with the boring bar axle, and the boring bar axle is supported by four boring bar supports; Two boring bar supports are fixed on the base; In addition two boring bar supports are installed on the firm banking, are equipped with manyly boring cutter on the boring bar axle, all use jackscrew fastening; Symmetric arrangement four hydraulic cylinders in the middle of base and the firm banking, and workbench is installed on the hydraulic cylinder.Boring bar cover in the boring bar support adopts vinyon.Base and firm banking all adopt the assembly unit of Q345 steel plate to be welded.
The beneficial effect of the utility model is: through the dual-active joint boring bar axle and actuating unit are coupled together, greatly reduce in the bore hole process and vibrate the actuating unit Effect on Performance.
Be used for of the production and processing of colliery supporting structure spare like base, list (two) connecting rod, back timber, caving shield, tail boom, front-axle beam.The processing in different pitch-rows, aperture can be satisfied, the porous concentricity can be guaranteed preferably.Reduced the input of colliery support medium-sized and small enterprises, improved the assembly quality of hydraulic support structural member, designed unique, rational in infrastructure, easy and simple to handle, maintenance easily main equipment.
Description of drawings
