Abstract
The utility model relates to a special purpose machine tool used for pipe expanding of an aluminium alloy motor casing. The machine tool is characterized by mainly comprising a stander, a hydraulic mechanism and a hole expansion mechanism; the hole expansion mechanism fixed on the stander includes an expansion sleeve, an inner pull core and a positioning sleeve, wherein the expansion sleeve is an elastic whole comprising a plurality of equal expansion sleeve sections, the axial section of an expansion sleeve inner hole is an inverted-splay taper, circumferential grooves are arranged at two side ends of the expansion sleeve, circumferential springs are arranged in the grooves, the shape of the excircle at the front end of the inner pull core is matched with that of the expansion sleeve inner hole, and the inner pull core is placed in the expansion sleeve inner hole. The utility model has benefits that an ellipse appearing on the aluminium alloy motor casing after compression resistance is expanded by utilizing the expansion of an inner sleeve, so as to ensure the precision of the inner hole of the casing, and the hole expanding precision can be controlled within 0.04. As one aluminum alloy motor casing is machined through one inching of a pedal plate, the machining time is saved, the production efficiency is improved, one person can use the hole expanding machine to machine 100 aluminum alloy motor casings every day, and the dimensional tolerance completely meets the requirements of customers.
Description
Technical field
The utility model belongs to the aluminium alloy special processing equipment, relates in particular to a kind of aluminium alloy electric casing expander special purpose machine tool.
Background technology
The motor casing product need be very high to the tolerance grade requirement of motor casing endoporus because of motor configuration, and resistance to compression motor casing section bar can't reach tolerance in forming process.Usually take dual mode, a kind of is the internal diameter turning process, promptly with the special fixture motor casing that is installed internal diameter is carried out turning to reach processing request on lathe.This kind mode processing cost is higher, lathe personnel operation technical ability is also required very high, and percent defective is very high, processes quantity every day and is about 200.Another kind of mode is an endoporus inner core hydraulic way, is about to inner core and is placed in the casing bore ends and utilizes forcing press that inner core is pressed onto the other end from casing endoporus one end to get final product, and inner core overall dimensions precision can satisfy the common customer requirement.This kind method can guarantee the motor casing ovality.But for as servomotor, the motor casing that precision such as brushless electric machine are very high can't meet the demands at all, and can cause scuffing to endoporus in press process, and fineness can't be guaranteed.
The utility model content
The purpose of this utility model is to overcome the deficiency of above-mentioned technology; and provide a kind of aluminium alloy electric casing expander special purpose machine tool; the reaming lathe is that the ellipse that the expansion of rising of cover occurs after resistance to compression the aluminium alloy electric casing in utilizing carries out reaming; to guarantee casing endoporus precision, its reaming precision can be controlled in 0.04.
The utility model for achieving the above object, by the following technical solutions: a kind of aluminium alloy electric casing expander special purpose machine tool, it is characterized in that: mainly by frame, the hydraulic mechanism and the holes mechanism that rises constitute, the described holes mechanism that rises that is fixed on the frame comprises ringfeder, in draw core and positioning sleeve, described ringfeder constitutes elasticity integral body by the ringfeder lobe of some even five equilibriums, the axial cross section of ringfeder endoporus is the tapering of falling the Eight characters, described ringfeder two side ends is provided with circumferential groove, be equipped with the circumference spring in the groove, draw anterior cylindrical shape of core and ringfeder endoporus to mate in described, in draw core to place in the ringfeder endoporus.
Described ringfeder evenly is slit into the 4-8 equal portions respectively, and the ringfeder hole taper is 5 °.
Draw the core rear end to support in described, and be connected with the oil cylinder piston bar of hydraulic mechanism by adpting flange by the positioning sleeve that is fixed on the support.
Beneficial effect: the ellipse that the expansion of rising of cover occurs after resistance to compression the aluminium alloy electric casing in utilizing carries out reaming, and to guarantee casing endoporus precision, its reaming precision can be controlled in 0.04.Make product aborning need not every all measure, saved man-hour, its mode of operation is simple and practical, the every crawl of pedal is once promptly processed one, save process time, improved production efficiency, by statistics, staving press one people's processing capacity every day is 1000 now, and dimensional tolerance meets the requirements of the customers fully.

The specific embodiment
Describe the specific embodiment of the present utility model in detail below in conjunction with accompanying drawing and preferred embodiment.As shown in the figure,
A kind of aluminium alloy electric casing expander special purpose machine tool, mainly constitute by frame 1, hydraulic mechanism 7 and the holes mechanism 12 that rises, the described holes mechanism that rises that is fixed on the frame comprise ringfeder 2, in draw core 3 and positioning sleeve 4, described ringfeder constitutes elasticity integral body by the ringfeder lobe of some even five equilibriums, the axial cross section of ringfeder endoporus is the tapering of falling the Eight characters, described ringfeder two side ends is provided with circumferential groove 5, be equipped with circumference spring 6 in the groove, draw anterior cylindrical shape of core and ringfeder endoporus to mate in described, in draw core to place in the ringfeder endoporus.Described ringfeder evenly is slit into the 4-8 equal portions respectively, and the ringfeder hole taper is 5 °.Draw the core rear end to support in described, and be connected with oil cylinder 8 piston rods of hydraulic mechanism by adpting flange 11 by the positioning sleeve that is fixed on the support 10.
Operation principle: mainly be to draw the tapering of falling the Eight characters effect of cooperatively interacting between core and the outer expanding sleeve in relying on, operate that its tapering is 5 °.During operation, ringfeder evenly is slit into the 6-8 equal portions respectively, then with the tension of circumference spring handle ringfeder, ringfeder is drawn on the core in being enclosed within not split mode, utilize hydraulic power to draw the core retraction in making, ringfeder is then by the tapering interaction force, outwards evenly expansion, cover motor case 9 internal diameters are outside risen greatly, so just can reach its required precision.The digital navigation system of the size of installing on the lathe simultaneously, can guarantee the uniformity in the middle of the operating process fully.Reaming scope: warp in minimum:
50mm, maximum inner diameter:
450mm.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.Every foundation technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
