Abstract
A butt boring machine for machining structural parts of mining hydraulic supports belongs to the field of manufacture of machinery. The technical scheme includes that two power transmissions are respectively fixed onto fixing bases by threaded pairs and are adjusted, a spindle of each power transmission is connected with a boring bar shaft by double movable joints, each boring bar shaft is supported by three boring bar supports, a boring tool is mounted on each boring bar shaft and fixed by a jack screw, four hydraulic cylinders are symmetrically arranged between the two fixing bases, and an operating platform is mounted on the hydraulic cylinder. The butt boring machine has the advantages that components at two ends of the butt boring machine are symmetrically arranged and positioned by the same structure, the three boring bar supports at each end of the butt boring machine can simultaneously realize fixing and supporting effects, the requirement on concentricity of an assembling hole is met assuredly, and the butt boring machine is easy in operation and high in practicality. In addition, the butt boring machine can meet requirements of machining holes with different pitches and diameters, concentricity of multiple holes can be guaranteed, and assembling quality of the structural parts of the hydraulic supports is improved. Besides, the butt boring machine is novel in design, reasonable in structure, convenient in operation and easy to repair.
Description
Technical field
The utility model relates to a kind of correct 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 correct 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: two cover actuating units are fixed on the firm banking with screw thread pair respectively and adjust; The main shaft of every cover actuating unit is connected by the dual-active joint with the boring bar axle; Every boring bar axle supports by three boring bar supports, on the boring bar axle boring cutter is installed, and is fastening with jackscrew; Symmetric arrangement four hydraulic cylinders in the middle of two firm bankings, and workbench is installed on the hydraulic cylinder.Being equipped with four up and down and regulating bolts of boring bar support, middle boring bar cover adopts vinyon.Two firm bankings 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.The two ends symmetric arrangement adopts same structure location, and 3 boring bar supports of every end play the effect of fixed support simultaneously, has guaranteed the concentricity requirement of pilot hole.Easy to operate, practicality is stronger.Reduced the input of colliery support medium-sized and small enterprises to main equipment.Can satisfy the processing in different pitch-rows, aperture, can guarantee the porous concentricity, improve the assembly quality of hydraulic support structural member.Novel in design, rational in infrastructure, easy to operate, maintenance easily.

The specific embodiment
Specify the details and the working condition of the utility model in conjunction with Fig. 1, Fig. 2, Fig. 3.Two cover actuating units 1 are fixed on the firm banking 5 with screw thread pair respectively and adjust; The main shaft of every cover actuating unit 1 is connected by dual-active joint 2 with boring bar axle 4; Every boring bar axle 4 supports by three boring bar supports 3; Boring cutter 7 is installed on the boring bar axle 4, and fastening with jackscrew 8, boring bar axle 4 is along with the swivel feeding of actuating unit 1 main shaft carries out work; The vibrations that produce in the bore hole process can be reduced, and the bore hole of different in width support can be changed through the relative position of regulating two cover actuating units 1; Symmetric arrangement four hydraulic cylinders 9 in the middle of two firm bankings 5, and workbench 6 is installed on the hydraulic cylinder 9, can pass through the height of the lift adjustment workbench 6 of hydraulic cylinder 9, is implemented in the height of adjustment bore hole in the altitude range;
Being equipped with four up and down and regulating bolts 10 of boring bar support 3; Middle boring bar cover 11 adopts vinyon; Adjust the axiality of boring bar through the relative position of regulating bolt 10 around the adjustment; Boring bar cover 11 adopts vinyon, can reduce the vibrations and the noise of boring bar, and is convenient to change; Two firm bankings 5 all adopt the assembly unit of Q345 steel plate to be welded, and simple for production, structure is more stable.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.The two ends symmetric arrangement adopts same structure location, and 3 boring bar supports of every end play the effect of fixed support simultaneously, has guaranteed the concentricity requirement of pilot hole, and easy to operate, practicality is stronger, has reduced the input of colliery support medium-sized and small enterprises to main equipment.Can satisfy the processing in different pitch-rows, aperture, can guarantee the porous concentricity, improve the assembly quality of hydraulic support structural member.Novel in design, rational in infrastructure, easy to operate, maintenance easily.
