Description

Technical Field

[0001] The invention relates to the technical field of drilling machines, in particular to a drilling machine for machining a casing of an automobile wiper motor which is convenient for chip removal. Background Art

[0002] The car wiper motor housing is an important part of the car wiper motor. It is generally made of aluminum alloy and other materials, with good strength, corrosion resistance and heat dissipation. Its function is to protect the winding, commutator, brushes and other precision parts inside the wiper motor from external dust, moisture, vibration and other factors to ensure the normal operation of the motor. At the same time, the housing is usually provided with mounting holes and other structures to facilitate the installation of the wiper motor on the car, and the reasonable structural design is conducive to the connection and coordination between the motor and the wiper transmission mechanism to realize the swinging action of the wiper to meet the needs of the car to clean the windshield under different weather conditions; When processing the mounting holes on the automobile wiper motor housing, a large amount of chips are usually generated. The chips will accumulate in the hole, intensifying the friction between the drill bit and the hole wall and the chips, increasing the cutting force, causing the drill bit to wear faster or even break. The heat generated by the chip accumulation is difficult to dissipate, which increases the drill bit temperature, reduces its hardness and wear resistance, and affects its service life. Chip blockage will also cause the drilling size accuracy to decrease, the surface roughness to increase, the hole diameter to expand or decrease, the hole wall to be uneven, and other problems, which seriously affect the processing quality and even cause the workpiece to be scrapped. Therefore, we proposed a automobile wiper motor housing processing drilling machine that is easy to remove chips. Summary of the invention

[0013] The present invention has the beneficial effects: 1. The present invention sets a countersunk drill bit. When it is necessary to drill a countersunk hole, the position of the protruding column is adjusted to make it fit into the countersunk drill bit, and the countersunk drill bit and the hole-opening drill bit are driven to feed synchronously, so that the countersunk hole-shaped mounting hole can be opened at one time, reducing the auxiliary time caused by multiple operations, speeding up the production progress, avoiding the errors caused by multiple positioning, improving the hole opening accuracy, and ensuring the accuracy of the hole size and position.

[0016] 4. The present invention sets a buffer column, and the buffer cylinder slides on the surface of the buffer column.
