Problems solved by technology

[0003] The grinding and manufacturing process of the above-mentioned traditional drill needle includes two forward and return strokes. The first forward stroke first grinds the first blade surface, and after returning to the origin, the second forward stroke grinds the second blade surface, and finally returns to the origin. The whole grinding manufacturing process is not only time-consuming and labor-intensive, but also cannot improve work efficiency, which is the biggest problem of this technology

Embodiment Construction

[0014] In order to make the object, technical solution and advantages of the present invention clearer, the following examples further describe the present invention in detail. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0015] A kind of drill pin secondary grinding manufacturing process, according to figure 1 Shown: schematically shows the plane configuration structure diagram of the present invention, the whole drill grinding mechanism includes: feeding mechanism 10, first mechanical arm 20, turret mechanism 30, grinding mechanism 40, second mechanical arm 50, drill edge detection mechanism 60. The third mechanical arm 70 and the discharging mechanism 80; wherein: the drill needle 90 to be ground is first transported to the position by the feeding mechanism 10, and then the first mechanical arm 20 grabs the drill needle 90 to be ground from the feeding mechanism to ...

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】 [0001] The invention relates to the manufacturing process of secondary grinding of drill pins, mainly aiming at grinding one edge surface of the drill pin in the forward stroke and grinding the other edge edge surface of the drill pin in the return stroke during the grinding process. 【Background technique】 [0002] according to figure 1 and figure 2 Shown are the front view and the top view of the drill. The drill 90 includes two blade surfaces 91, 92. The blade surfaces 91, 92 are composed of a clearance angle 93 of 15° and a backlash foot 94 of 30°. The traditional drill The grinding manufacturing process of 90 includes two forward and return manufacturing processes, among which: the first forward and return manufacturing process is: 90°alignment—90°rotation—needle pressing—the first blade surface grinding—return. The manufacturing process of the second forward and return strokes is: cancel pressing needle—rotate 180°—press needle—grind the second blad...
