Abstract
The invention discloses a tubular rear axle press-fitting device which comprises a bottom plate, L-shaped positioning bases, a V-shaped supporting block, a type block, a positioning flange, a positioning pin and an oil cylinder. The bottom plate is in a long strip shape. The L-shaped positioning bases with side walls opposite are installed at the two ends of the upper surface of the bottom plate through bolts respectively. A V-shaped supporting block with an opening facing upwards is installed at the portion, between the two L-shaped positioning bases, of the bottom plate through a bolt. The positioning flange is installed on the outer side wall of the right-angle side of one L-shaped positioning base through a bolt, and the oil cylinder is installed on the inner side wall of the right-angle side of the other L-shaped positioning base through a bolt. A push rod of the oil cylinder penetrates through the side walls of the right-angle sides of the L-shaped positioning bases to be connected with an ejector pin. Positioning pins are arranged in the outer side walls of the right-angle sides of the L-shaped positioning bases and two positioning blocks in a penetrating mode respectively. The current situation that after an existing tubular rear axle is machined, coaxiality is not stable is eliminated, and the manufacturing cycle of a whole rear axle is shortened while the production efficiency is greatly improved.
Description
Technical field
The present invention relates to a kind of press-loading device of mechanical field, is a kind of equipment for press-fiting tubular type back axle specifically.
Background technology
Popularizing at present along with new-energy automobile equipment, the exploitation of novel low-speed electronic car and development, will become a part indispensable in later stage China Automobile Industry.In present whole automobile component part supply market, the processing and manufacturing of new forms of energy back axle all lacks ripe technological parameter and instructs and equipment support, the design and development of non-driven back axle also continues to use old and traditional processing technology and equipment in a large number, and this present situation often can not meet in enormous quantities, the Production requirement of high accuracy, high interchangeability.Although traditional postwelding processing eliminates part Guan Liang because welding the distortion caused, the multiple clamping of processing itself and sophisticated equipment are difficult to introduce the bottleneck becoming and restrict whole production, and this kind of mode can not ensure good stable axiality requirement.The instability of the accuracy of manufacture will directly affect the service life of whole vehicle body, eats tire, partially stops, travels the problems such as abnormal sound and also will in succession occur.
Summary of the invention
Object of the present invention provides a kind of equipment for press-fiting tubular type back axle, improves the stable axiality of tubular type back axle.
For achieving the above object, technical scheme of the present invention is: a kind of tubular type back axle press-loading device, comprise base plate, L-type positioning seat, V-type back-up block, locating flange, alignment pin, oil cylinder, described base plate is strip, respectively by bolt, the relative L-type positioning seat of sidewall is installed at upper surface two ends, described base, base plate between two L-type positioning seats is provided with the V-type back-up block of opening upwards by bolt, the lateral wall of a L-type positioning seat right-angle side is wherein provided with locating flange by bolt, the madial wall of another L-type positioning seat right-angle side is provided with oil cylinder by bolt, and the push rod of described oil cylinder runs through the sidewall of L-type positioning seat right-angle side and is connected with thimble, described base plate is also provided with the locating piece for positioning and fixing tube formula back axle of two groups of parallel arrangements, run through respectively on the lateral wall of described L-type positioning seat right-angle side and on two groups of locating pieces and have alignment pin, described thimble, the center of locating flange and two groups of locating pieces is on same perpendicular
Owing to adopting technique scheme, beneficial effect of the present invention: solve the present situation that existing tubular type back axle machines rear ensuring coaxiality instability, carry out automatically controlled fixed point to the combination of the Guan Liang after Boring, wheel hub installation shaft and brake caliper anchor plate to press-fit, eliminate the axiality that the gap in original manual press-loading process causes excessive, the problems such as brake caliper anchor plate angle asymmetry, shorten the manufacturing cycle of whole back axle while significantly enhancing productivity.
