Abstract
The invention relates to a twice grinding manufacturing method of drill points, which is characterized in that 180 degrees counterpoint is adopted on a leaving procedure; a first active face grinding is carried out after a pin pressing; the pin pressing is cancelled first in a returning procedure and then the drill points are rotated by 180 degrees; and then a second active face grinding is carried out after a pin pressing. The method has the advantages that half working procedure and working time are saved at the same feeding speed; the working efficiency of the drill point grinding can be improved; and the man-power and working hours can be saved.
Description
[technical field]
The present invention relates to drill point regrind manufacturing process, mainly is in the process of lapping, goes journey to grind one side sword face of drill point, grinds drill point another side sword face during backhaul again.
[background technology]
According to illustrated in figures 1 and 2 be front view and the vertical view of drill point, drill point 90 comprises two sword faces 91,92, sword face 91, the 92nd is made up of the back crack pin 94 of 15 ° front clearance angles 93 and 30 °, the grinding manufacturing process of tradition drill point 90 comprises two manufacturing process that go journey and backhaul, and wherein: first goes the manufacturing process of journey and backhaul to be: the grinding-backhaul of 90 ° of contraposition-90 ° rotation-pressing-first sword faces.Second is gone the manufacturing process of journey and backhaul to be: cancellation pressing-Rotate 180 °-pressing-second sword face grinding-backhaul.
The grinding manufacturing process of above-mentioned traditional drill point comprises that two are gone journey and backhaul, first goes journey to grind the first sword face earlier, get back to after the initial point, second is gone journey to grind the second sword face again, get back to initial point at last, whole grinding manufacturing process is not only wasted time and energy expense manually, and can't promote operating efficiency, and this is the problem place of this technology maximum.
[summary of the invention]
The present invention provides a kind of operating efficiency that improved for addressing the above problem, and saves time and the drill point regrind method of manpower.
The technical scheme that the present invention addresses the above problem is: a kind of drill point regrind manufacture method, it is characterized in that, and go journey to adopt 180 ° of contrapositions earlier, after the pressing, namely carry out the first sword face and grind, cancellation pressing earlier during backhaul, Rotate 180 ° again, after the pressing, namely carry out the second sword face and grind, whole grinding manufacturing process only needs one and goes journey and backhaul to finish, go journey to grind the first sword face earlier, the second sword face is ground in backhaul again.
The first sword face of drill point and the second sword face comprise 15 ° front clearance pin and 30 ° back crack pin.
The invention has the beneficial effects as follows: under identical work speed, save workflow and the working time of half, can promote the operating efficiency that drill point grinds, save manpower and man-hour.

[specific embodiment]
In order to make purpose of the present invention, technical scheme and advantage clearer, following examples are further elaborated to the present invention.Should be appreciated that specific embodiment described herein only in order to explaining the present invention, and be not used in restriction the present invention.
A kind of drill point regrind manufacturing process, according to shown in Figure 1: illustrated planar arrangement feature figure of the present invention, whole drill point grinding mechanism comprises: feeding mechanism 10, first mechanical arm 20, header turning tower structure 30, grinding mechanism 40, second mechanical arm 50, drill lip testing agency 60, the 3rd mechanical arm 70, discharging mechanism 80; Wherein: drill point 90 to be ground is delivered to the location by feeding mechanism 10 earlier, by first mechanical arm 20 drill point 90 to be ground is grasped to header turning tower structure 30 from feeding mechanism, two the sword faces 91,92 (comprising 15 ° front clearance pin 93 and 30 ° back crack pin 94) that grind out drill point 90 by header turning tower structure 40 are afterwards (as Fig. 4, shown in Figure 5: be to grind behind the drill point crack pin and front clearance foot-propelled described in the present invention to make schematic diagram more again.) being fixed by header turning tower structure 30 turns to drill lip testing agency 60 again, to grind drill point 90 by second robotic arm 50 again grasps to drill lip testing agency 60 from header turning tower structure 30, carry out drill lip and detect operation, drill point 90 after detecting, grasped to discharging mechanism 80 by the 3rd robotic arm 70 again, finish whole drill point and grind and the detection operator.
Workflow comprises that one is gone the drill point of journey and backhaul to grind manufacturing process, and wherein: removing the drill point grinding manufacturing process of journey is that 180 ° of contraposition-pressing-first sword faces grind; The drill point of backhaul grinds manufacturing process and grinds for cancellation pressing-Rotate 180 °-pressing-second sword face.
By the made drill point regrind manufacturing process of method provided by the present invention, on practical operation was used again: whole drill point ground manufacturing process, only needing one goes journey and backhaul just can finish, go journey to grind the first sword face 91 (comprising 15 ° front clearance pin 93 and 30 ° back crack pin 94) of drill point 90 earlier, the second sword face 92 (comprising 15 ° front clearance pin 93 and 30 ° back crack pin 94) of drill point 90 is ground in backhaul again, half workflow and working time can be saved, the operating efficiency that drill point grinds can be effectively promoted.
The above only is preferred embodiment of the present invention, not in order to limiting the present invention, all any modifications of doing within the spirit and principles in the present invention, is equal to and replaces and improvement etc., all should be included within protection scope of the present invention.
Claims (2)
1. a drill point regrind manufacture method is characterized in that, goes journey to adopt earlier 180 ° of contrapositions, after the pressing, namely carry out the first sword face and grind, and cancellation pressing earlier during backhaul, Rotate 180 ° after the pressing, namely carries out the second sword face and grinds again.
2. according to the described drill point regrind of claim manufacture method, it is characterized in that the first sword face of drill point and the second sword face comprise 15 ° front clearance pin and 30 ° back crack pin.
