Abstract
The invention provides a process for manufacturing a vehicle glass lifting motor worm, relating to a production process of worms. The process comprises the procedures of: tooth surface cold extruding, drilling, boring, reaming and hole surface pressure polishing. The adopted material is high-quality carbon structural steel, i.e. No.45 steel; the center bore diameter of the worm is not more than 4 mm; and the roughnesses of the tooth surface and the hole surface are respectively 0.6 and 0.8, the radial jumping of reference circles relative to center holes is not more than 0.01 mm, and the bore diameter tolerance is 0.01 mm. Due to the adoption of the high-quality carbon structural steel, the product has the advantages of environment protection, high strength, good wear resistance, stable performance and long test service life up to above 1.1millions of times, thereby improving the quality of a vehicle glass lifter motor.
Description
Technical field:
The present invention relates to the manufacturing process of a kind of worm screw, be specifically related to a kind of vehicle glass lifting motor worm manufacturing process.
Background technology:
Along with people are more and more higher to the requirement of security, comfortableness and the reliability of automobile, design is again the key of car door design as vehicle body main accessories door accessories, how efficiently, accurately, intelligently carry out the door accessories design work, shortening the design cycle, is an emphasis of present automobile industry research.Automobile door and window glass will guarantee that not only the driver has enough visual angles, with safe driving and driving; Simultaneously, for satisfying the needs of ride comfort, the position of glass often needs to adjust, thereby the scope of glass adjustment and manipulation flexible just becomes important performance indications.Guarantee that the mechanism that vehicle glass is adjusted flexibly is exactly a glass-frame riser, it also is a vitals of automotive safety and comfortableness.
Micromachine is the heart of automobile glass lifter, and worm screw is the very crucial parts of motor, and it directly influences performances such as the noise of motor and service life.
At present both at home and abroad auto parts and components manufacturing enterprise all adopts low-carbon (LC) (homemade) or middle carbon (daily output) automatic steel to produce worm screw, because lead tolerance or sulfur content are higher in this type of material, pollution and waste material are seriously polluted in the process; Not environmental protection of product; Intensity is low; Wear no resistance; Unstable properties; The test life-span is 1-3 ten thousand times, yet the standard of automobile industry is more than 30,000 times, is design focal point so improve the quality of automobile glass lifter motor worm.
Summary of the invention:
The purpose of this invention is to provide a kind of vehicle glass lifting motor worm manufacturing process, it adopts carbon constructional quality steel, product environmental protection, the intensity height, wearability is good, stable performance, testing service life is more than 110,000 times, thereby has improved the quality of automobile glass lifter motor.
In order to solve the existing problem of background technology, the present invention is by the following technical solutions: its technological process of production is: flank of tooth cold extrusion → boring → bore hole → fraising → hole face press polish.
The material that the present invention adopts is: carbon constructional quality steel, i.e. No. 45 steel.
Adopt product center aperture that production technology of the present invention produces to be≤4mm, the flank of tooth of worm screw and hole surface roughness are 0.6 and 0.8, and its reference circle is with respect to the circular runout≤0.01mm of centre bore, and hole tolerance is 0.01mm.
The hollow microneedle worm screw that the present invention adopts carbon constructional quality steel production in enormous quantities form and position tolerance and roughness to have relatively high expectations, product environmental protection, intensity height, wearability is good, stable performance, testing service life is more than 110,000 times, thereby has improved the quality of automobile glass lifter motor.
Description of drawings:
Fig. 1 is a product structure schematic diagram of the present invention.
The specific embodiment:
With reference to Fig. 1, this specific embodiment by the following technical solutions: its technological process of production is: flank of tooth cold extrusion → boring → bore hole → fraising → hole face press polish.
The material that the present invention adopts is: carbon constructional quality steel, i.e. No. 45 steel.
Adopt product center aperture that production technology of the present invention produces to be≤4mm, the flank of tooth of worm screw and hole surface roughness are 0.6 and 0.8, and its reference circle is with respect to the circular runout≤0.01mm of centre bore, and hole tolerance is 0.01mm.
Because this specific embodiment adopts the cold-stamped mode to squeeze out the flank of tooth on to be processed, the extrusion sections dimensionally stable, any surface finish, and cold-extruded part stock utilization height can save material; The productivity ratio height: the efficient with cold extrusion method manufacturing machine part is very high, and particularly the big part of production lot is produced comparable machining with cold extrusion method and improved several times, tens times even hundred times; Cold-extruded part intensity height, wearability are good.
Adopt boring, can guarantee the concentricity of flank of tooth reference circle and centre bore; Adopt ream, can guarantee hole tolerance; Adopt press polish, can guarantee hole face fineness.
The hollow microneedle worm screw that this specific embodiment adopts carbon constructional quality steel production in enormous quantities form and position tolerance and roughness to have relatively high expectations, product environmental protection, intensity height, wearability is good, stable performance, testing service life is more than 110,000 times, thereby has improved the quality of automobile glass lifter motor.
