Abstract
The invention discloses a down-hole rock drilling bit pressing tooth guiding device, belongs to a pressing tool for pressing alloy teeth into drill bit tooth holes, and aims to provide a drill bit tooth pressing tool with convenience and fastness in operation, low labor intensity and capability of improving product quality. The guiding device comprises an upright post (5), a lifting arm (4) fixed on the upright post, a guiding sleeve (10) fixed on the lifting arm and provided with a feeding hole (15) on the lateral surface, a guiding pressure rod (8) arranged in the guiding sleeve, and a spring (9) sleeved on the guiding pressure rod. The guiding device thoroughly overcomes the defects that the efficiency is low and the labor intensity is high in manual preassembly of alloy teeth and the coaxiality of the alloy teeth and the tooth holes is difficult to ensure; and the guiding device has the advantages of simple structure, convenience in operation, high qualification rate and the like. The guiding device is process equipment for manufacturing a rock drilling bit.
Description
Technical field
The present invention relates to a kind of technological equipment of making rock drill bit, relate in particular to and a kind of carbide button is pressed into the press fitting device in the bore bit body perforation.
Background technology:The down-the-hole drilling bore bit is a drill rod commonly used in mine and the engineering construction, it by the termination be distributed with the bore bit body of a plurality of perforations, the spherical carbide button that is fixed in the said perforation constitutes.Normally adopt at present the mode of interference fit, utilize forcing press that carbide button is pressed in the perforation and fix.Yet, because the matching allowance between carbide button and the perforation is bigger, before being press-fitted, must adopt manual mode that carbide button is pre-installed on the perforation earlier, with "painted-face" character in opera it is knocked in then, with forcing press carbide button is pressed in the perforation fully more at last.This method not only troublesome poeration, efficient is low, and is difficult to guarantee that carbide button is coaxial with perforation during manual prepackage, is easy to generate waste product.
Summary of the invention:In order to overcome the defective that exists in the prior art, the present invention aims to provide a kind of down-the-hole drilling bore bit convenient to operation, that labour intensity is little, product percent of pass is high and presses the tooth guider.
To achieve these goals, the present invention adopts following technical scheme: it comprises column, be fixed on lifting arm on this column, be fixed on this lifting arm and the side be provided with charging aperture fairlead, be located at guiding depression bar in this fairlead, be enclosed within the spring on this guiding depression bar.
Column is a ball screw, and the feed screw nut who is located on this ball screw is arranged in the lower end of lifting arm; The position that on lifting arm, corresponds respectively to said ball screw and fairlead is provided with a set lever separately; The lower surface of guiding depression bar is provided with the pit of circular arc type.
With prior art relatively, the present invention has been owing to adopted technique scheme, overcome thoroughly therefore that manual prepackage carbide button efficient is low, labour intensity big, has been difficult to the defective that guarantees that carbide button and perforation are coaxial; Have plurality of advantages such as simple in structure, easy to operate, good product quality, qualification rate height.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Among the figure: T type bolt 1 base 2 feed screw nuts 3 lifting arms 4 columns 5 set levers 6 press ram 7 guiding depression bars 8 springs 9 fairleads 10 carbide buttons 11 bore bit bodies 12 positioning tools 13 workbench 14 charging apertures 15
The specific embodiment:Below in conjunction with accompanying drawing and concrete embodiment the present invention is described further:
As shown in Figure 1: column 5 is fixed on the base 2, is fixed with lifting arm 4 on this column, is fixed with fairlead 10 on this lifting arm; Be provided with guiding depression bar 8 moving up and down in this fairlead, spring 9 is enclosed within on this guiding depression bar.For the ease of regulating the height of lifting arm 4, column 5 adopts ball screws, in the lower end of lifting arm 4 feed screw nut 3 who is located on this ball screw is arranged, and rotates this feed screw nut and can promote the lifting arm 4 that sky is enclosed within on the said ball screw and move up and down; Be moved at work or rotate for fear of lifting arm 4, the position corresponding to ball screw on this lifting arm is provided with set lever 6.In order to adapt to the product of all size, fairlead 10 adopts dismountable structure; Rotate or move for fear of fairlead 10, the position corresponding to this fairlead on lifting arm 4 is provided with another set lever 6.In order to increase the contact area with carbide button 11, the lower surface of guiding depression bar 8 is provided with the pit that matches with the carbide button arc surface.
During work, base 2 is fixed on the workbench 14 through T type bolt 1, bore bit body 12 is fixed on the workbench 14 through positioning tool 13; Regulate the height of lifting arm 4 and guarantee that fairlead 10 is coaxial with the perforation of bore bit body 12; Then carbide button 11 is pushed from charging aperture 15; Make it fall into the perforation of bore bit body 12 and realize the location, through press ram 7 carbide button 11 is pressed in the perforation at last and gets final product along fairlead 10.
