Double-end-surface grinding equipment of micro drillstock

Abstract

The invention belongs to grinding tools, and particularly relates to double-end-surface grinding equipment of a micro drillstock. The double-end-surface grinding equipment of the micro drillstock comprises a machine body, and is characterized in that a grinding assembly is arranged on the machine body and is composed of two grinding wheels and a rotary crankset arranged between the two grinding wheels in parallel, a feeding hopper is arrange above the grinding assembly, a collection mechanism is arranged under the grinding assembly, the feeding hopper and the collection mechanism are both tangent with the rotary crankset, and a pressing belt is arranged at the edge of the rotary crankset between two tangent points. The double-end-surface grinding equipment of the micro drillstock improves the yield to above 99.98%, simplifies the whole operation procedure of micro drill production, accelerates the material circulation, improves production efficiency, relieves labor intensity, and saves labor cost.

Description

technical field [0001] The invention belongs to a grinding tool, in particular to a grinding device for double-end faces of a micro-drill handle. Background technique [0002] At present, the grinding of micro-drill shanks in China is mostly processed by surface grinding equipment. The length and size of each drill shank blank are different, and a series of problems will occur, which will affect product production. Therefore, for welding with different diameters, the flatness of the end surface of the drill shank blank It affects the quality of different-diameter welding, and the flatness of the end surface processed by the current surface grinding equipment cannot meet the requirements of reducing the defects of different-diameter welding, and it consumes a lot of manpower; the researchers have repeatedly studied the different-diameter plane automatic welding process machinery After the process follow-up test, it was found that the poor quality part in the welding process ...

Problems solved by technology

[0002] At present, the grinding of micro-drill shanks in China is mostly processed by surface grinding equipment. The length and size of each drill shank blank are different, and a series of problems will occur, which will affect product production. Therefore, for welding with different diameters, the flatness of the end surface of the drill shank blank It affects the quality of different-diameter welding, and the flatness of the end surface processed by the current surface grinding equipment cannot meet the requirements of reducing the defects of different-diameter welding, and it consumes a lot of manpower; the researchers have repeatedly studied the different-diameter plane automatic welding process machinery After the process follow-up test, it was found that the poor quality part in the welding process was caused by the different lengths of the drill shank blanks and the poor end faces. After repeated tests and adjustments, it was found that the main reason was the mismatch between the surface grinding equipment and the equipment fixtures. Perfect, resulting in low machining accuracy, rough and uneven material length and end surface, and complex process and low efficiency, and the original process requires three people to cooperate with the work when the original process is practical for surface grinding. The tool is locked with a hexagon socket head screw, and one person puts the jig with the drill shank on the magnetic table of the machine and locks it, and manually operates the machine to smooth the two ends of the drill shank blank and control the length. Large and low production capacity (750 pieces per jig, only one jig can be processed at a time)
