Description
Technical field
The present invention relates to a kind of special fixture, relate in particular to a kind of special fixture of processing the rolling stock bogie side frame, can be widely used in the batch process of rolling stock Processing Side Frame, belong to technical field of tooling clamps.
Background technology
Bogie side frame is the important spare part of bogies for railway vehicles system, and its Performance And Reliability is for the technical merit important influence of rolling stock, and its quality good or not direct relation the traffic safety of rolling stock.
At present, the bogie side frame mechanical processing technique mainly contains central square frame two facades location, drawing strickle guide face location, several modes such as hydraulic clamp in the industry.But the product quality of utilizing the bogie side frame of these installation way location processing when actual processing is subjected to the restriction of spray quality, existence can not be according to the drawback of casting quality situation classification clamping and clamping difficulty, and the processing form and position tolerance is difficult to guarantee after causing the bogie side frame clamping easily, a delivery-check qualified rate of bogie side frame is low, finally influences the quality of bogie side frame and the control of production cost.
Summary of the invention
The technical program provides a kind of special fixture of processing the rolling stock bogie side frame, and the workbench work that partly cooperatively interacts by special fixture and centring means and bogie side frame production miller has effectively overcome bogie side frame complex contour clamping difficulty, size and form and position tolerance and has been difficult for guaranteeing, is difficult to realize shortcomings such as parts exchange.
A kind of special fixture of processing the rolling stock bogie side frame comprises centring means and positioning fixture two parts; Wherein centring means is the mounting platform of bogie side frame, and 3 alignment pins are arranged on the centring means, and the positioning key of symmetrical two projectioies is arranged on the work top of centring means; Positioning fixture comprises the anchor clamps base plate, claw, pressing plate and pressing plate screw rod, the positioning spline of two symmetries is arranged at the bottom of anchor clamps base plate, finish whole location for cooperating with the positioning key of processing work top, claw is positioned at the two ends, the left and right sides of anchor clamps base plate, leading screw on the claw is used for the degree of tightness of control claw, and pressing plate is symmetrical set between two claws, and each pressing plate is furnished with two pressing plate screw rods.
Working method: at first positioning fixture is hung on centring means, bogie side frame utilizes in the centring means alignment pin to finish preliminary centering then, positioning key by centring means compresses cooperate the location with the positioning spline of anchor clamps base plate in the positioning fixture after, utilizes leading screw to promote the clamping that claw is tentatively finished bogie side frame; The longitudinal median plane of bogie side frame is determined in line then, regulates the position of bogie side frame by the leading screw that rotates two ends, the left and right sides, holds out against the bogie side frame bottom, by pressing plate screw rod clamping platen, thereby finishes the location clamp operation; The axle box guide that guarantees arbitrary end face of bogie side frame by this special-purpose centralizer is not more than 4 to the symmetry of the longitudinal median plane of bogie side frame, and the axle box guide of an end is not more than 2 to the symmetry of the axle box guide of the other end.Sideframe pedestal keeps off two medial surfaces the perpendicularity of bogie side frame longitudinal centre line is not more than 0.5.
After finishing positioning and clamping work, utilize radial drilling machine to finish the processing in block key hole, then bogie side frame is specifically lifted bogie side frame production miller workbench together with exclusive clamps, the back, location clamps.Press right flank milling head, inclined-plane milling head button and left side circle navel face milling head respectively to the processing of drawing strickle guide face and central square frame two facades; Utilize special-purpose gauge self check simultaneously, in the quality that guarantees the bogie side frame product, shortened detection time.
Beneficial effect: utilize the cooperating of the workbench of the concrete and special drill press of special-purpose centring means, locating clip that the present invention designs to finish a clamping to foundry goods bogie side frame blank, accurate positioning can be widely used in the batch process of rolling stock Processing Side Frame.

The specific embodiment
As shown in Figure 1, a kind of special fixture of processing the rolling stock bogie side frame comprises centring means 2 and positioning fixture two parts; Wherein centring means 2 is the mounting platform of bogie side frame, and 3 alignment pins are arranged on the centring means 2, and the positioning key 3 of symmetrical two projectioies is arranged on the work top of centring means; Positioning fixture comprises anchor clamps base plate 4, claw 7, pressing plate 5 and pressing plate screw rod 6, the positioning spline of two symmetries is arranged at the bottom of anchor clamps base plate 4, finish whole location for cooperating with the positioning key 3 of work top, claw 7 is positioned at the two ends, the left and right sides of anchor clamps base plate, leading screw 8 on the claw 7 is used for the degree of tightness of control claw 7, and pressing plate 5 is symmetrical set between two claws 7, and each pressing plate 5 is furnished with two pressing plate screw rods 6.
At first positioning fixture is hung on centring means, bogie side frame utilizes in the centring means alignment pin to finish preliminary centering then, positioning key by centring means compresses cooperate the location with the positioning spline of anchor clamps base plate in the positioning fixture after, utilizes leading screw to promote the clamping that claw is tentatively finished bogie side frame; Find out the A1 point of bogie side frame one side afterwards, the A2 point, A3 point and bogie side frame opposite side symmetric points A1 ' point, A2 ' point, A3 ' point, determine A1A1 ', A2A2 ', A3A3 ' mid point is A1 " point; A2 " point, A3 " point; determine planes at these 3; this plane is the longitudinal median plane of bogie side frame measuring basis; the axle box guide of regulating arbitrary end face of bogie side frame according to longitudinal median plane is not more than 4 to the symmetry of the longitudinal median plane of bogie side frame; and the axle box guide of an end to the symmetry of the axle box guide of the other end to being not more than 2, sideframe pedestal keeps off two medial surfaces the perpendicularity of bogie side frame longitudinal centre line is not more than 0.5.This moment the hold-down bolt pressing plate, thereby finish the location clamp operation.
After finishing positioning and clamping work, utilize radial drilling machine to finish the processing in block key hole 12.
Then bogie side frame is specifically lifted bogie side frame production miller workbench together with exclusive clamps, the back, location clamps.Press right flank milling head, inclined-plane milling head button and left side circle navel face milling head respectively to the processing of drawing strickle guide face 10 and central square frame two facades 11; Utilize special-purpose gauge self check simultaneously, in the quality that guarantees the bogie side frame product, shortened detection time.
Facts have proved, the bogie side frame constant product quality of utilizing the positioner of the special use among the present invention and anchor clamps to cooperate aid such as special-purpose height gauge to produce, the bogie side frame qualification rate that casting back machine can be added processing is brought up to more than 95% by traditional 70%-80%.
