Description

A kind of processing technique of motor speed measuring tooth ring type thin wall members loading

Technical field

The present invention relates to the processing technique of a kind of thin-wall part, a kind of adding for motor speed measuring tooth ring type thin wall members loading Work technique.

Background technology

Along with commercial production quickly increases, the application of thin-walled workpiece is more and more extensive, due to these designs of part and wall Thick change complexity, traditional technique mainly has each step following: blanking, rough turn, half finish turning, boring, finish turning hole, gear hobbing, mill Scabbling face, the later stage processes, checks；The course of processing uses turnery processing, but in the course of processing, owing to detail rigidity is poor, holds Being easily generated deformation, the element precision therefore processed can not be guaranteed, and needs to use the method such as turning, technological compensa tion to correct shape, Cause its production efficiency low, difficult quality guarantee so that the efficiency of processing is difficult to play；The fierce market competition requires that product grinds Production cycle processed is shorter and shorter, and traditional processing technique and manufacture method have been difficult in adapt to the high-quality processing of this thin-walled parts Requirement.

Summary of the invention

It is simple that the technical problem to be solved in the present invention is to provide a kind of technique, and precision qualification rate is high, and the motor that efficiency is high Test the speed the processing technique of tooth ring type thin wall members loading.

In order to solve above-mentioned technical problem, the present invention provides the processing technique of a kind of motor speed measuring tooth ring type thin wall members loading, bag Include and have the following steps:

1) selection blanking:

Choose the seamless steel plate of Q345 of 12 millimeters thick, blanking blank outside diameter more than forming thin-walled part 10～11 millimeters, Inner circle is then less than forming thin-walled part 10～11 millimeters；

2) rough turn processing:

Rough turn ring gear inside and outside circle and end face on horizontal lathe, with profiled member ratio, cylindrical and interior circular error at 1.2 millimeters In, thickness error is in 1.1 millimeters；

3) finish turning drill jig seam:

Cooling at least 24 hours after rough turn, finish turning inner circle joins drill jig seam, and in finish turning, circular error is in 0.05 millimeter；

4) drilling and tapping:

Drilling machine uses drill jig boring, orifice chamfer 1X45 °；

5) finish turning two plane:

Using lathe finish turning two plane to drawing requirement, thickness error is in 0.100 millimeter, and roughness is to Ra3.2, and two is flat Beat less than 0.05 millimeter in face；

6) finish turning inside and outside circle:

With automobile-used chassis clamping ring gear on lathe, finish turning ring gear inside and outside circle to drawing requirement, chamfering deburring, cylindrical and The error of inner circle at 0.050 millimeter, roughness Ra 1.6；

7) burr processes:

Cylindrical gear hobbing, to drawing requirement, deburring, uses gear hobbing core tire J000.058 during gear hobbing；

8) zinc-plated carve characters:

Zinc-plated process is made on ring gear surface, and thickness of coating is 6～8 microns, uses metal Lettering pen to engrave ring gear numbering, it is simple to Inspection one by one record.

Employing the technical program following features: 1, owing to using vertical lathe to carry out turning ring gear, allows ring gear be nearly at certainly By suspended state, can effectively suppress the deformation of two planes of ring gear, the magnetic working table overcoming grinding machine can not solve ring gear change The problem of shape.Thus, efficiently solve the problem on deformation in the thin-wall part course of processing；2, due in finish turning drill jig step, After rough turn, need the cooling no less than 24 hours, its purpose is to avoid steel part to cross thermally-induced rigidity and be deteriorated；3, in finish turning Circle joins drill jig seam so that the precision of hole machined can be improved.

Further, in order in the step of drilling and tapping, it is to avoid thin-wall part deforms, and is lined with 20 millimeters during boring below ring gear Thick glass-cloth board, to prevent ring gear from deforming.

Detailed description of the invention

Specific embodiment is presented herein below technical solution of the present invention is further illustrated:

A kind of thin-wall part tests the speed the processing technique of ring gear, comprises the following steps that

1) selection blanking:

Choosing the seamless steel plate of Q345 of 12 millimeters, blank size is: Φ 430 × Φ 366 × 12 millimeters；Due to Q345 steel Material, has good mechanical property, can be with Reducing distortion；

2) rough turn processing:

Rough turn ring gear inside and outside circle and end face on C630 horizontal lathe, cylindrical is to Φ 422 ± 0.20 millimeters, inner circle to Φ 372 ± 0.20 millimeters, thickness to 9 ± 0.10 millimeter；Use horizontal lathe so that gravity balance suffered by ring gear, can reprocess Time reduce ring gear deformation；

3) finish turning drill jig seam:

Cooling at least 24 hours after rough turn, finish turning inner circle joins drill jig seam, finish turning inner circle to Φ 373+0.20 millimeters；By In heat can be produced in the course of processing, need the cooling no less than 24 hours, its purpose is to avoid steel part the most thermally-induced Rigidity is deteriorated；

4) drilling and tapping:

Drilling machine Z3035 uses drill jig bore 29-Φ 7 and 2-M8 hole, orifice chamfer 1X45 °, want below ring gear during boring Pad the glass-cloth board of upper 20 millimeters thick, it is ensured that ring gear is indeformable；

5) finish turning two plane:

Use lathe C518 finish turning two plane to drawing requirement, thickness car to 8+0.10 0 millimeter, roughness to Ra3.2, Two planes beat no more than 0.05 millimeter；

6) finish turning inside and outside circle:

With automobile-used chassis clamping ring gear on lathe C630, finish turning ring gear inside and outside circle to drawing requirement, chamfering deburring, outward Circle Φ 420 ± 0.05 millimeters, inner circle Φ 376+0.057 0 millimeter, roughness Ra 1.6；

7) burr processes:

8) zinc-plated carve characters:

Zinc-plated process is made on ring gear surface, and thickness of coating is 6 to 8 microns, uses metal Lettering pen to engrave ring gear numbering, it is simple to Inspection one by one record.

Above-described is only the preferred embodiment of the present invention, it is noted that for a person skilled in the art, Without departing under the processing technique premise of thin-wall part of the present invention, it is also possible to make some be made without creative work just can be complete The improvement become, these also should be considered as protection scope of the present invention, and these are all without effect and patent affect present invention enforcement Practicality.
