Abstract
The utility model discloses a four-hole-drill accurate positioning device for a flange head of a drive axle housing. The device comprises a vertical plate, an upper top plate, positioning guide rods, a drill bit, drill bushings, compression columns, an upper positioning base, spring and wedge pins, an angular positioning rod, a coarse positioning column, a middle sliding plate and an oil cylinder. Two sides of the whole device are fixed by a positioning guide rod respectively; four compression columns of the upper top plate are fixed at four corners and are provided with the drill bushings and the upper positioning base; and an inner bore coarse positioning column and the angular positioning device are arranged on the middle sliding plate. The four-hole-drill accurate positioning device for the flange head of the drive axle housing is simple in design structure and convenient to use; and the machining accuracy and the machining efficiency are improved.
Description
Technical field the utility model relates to field of mechanical technique, particularly driving axle housing flange head accurate positioning device.
The background technology driving axle housing is the important bearing part and the driving member of automobile, is the critical component that maintains vehicle operating safety, and the performance of axle housing directly influences the Acceptable life of automobile.Towards the driving axle housing of welding structure have that manufacturing process is simple, stock utilization is high, percent defective is low, productivity ratio is high and advantage such as low cost of manufacture outside, also have enough strength and stiffness, particularly its light weight, but than casting bridge shell safety and reliability.Therefore not only be used for light truck, car, minicar, also replace casting bridge shell gradually, be widely used in various in, heavy truck.
Flange head is applied on the driving axle housing as attaching parts.Weldering forward flange head is hole-drilled half smart base.Technology before is that flange head is not processed earlier, driving axle housing is dashed with three brill special planes flange head is carried out four hole drills again after weldering is accomplished.Require the four hole locations≤∮ 0.2 of flange head half smart base now, this just requires the location of multi-drill must precision high.At present, be that mandrel or outer shroud with fixed dimension carries out endoporus or external diameter location with four hole drill positioners of the similar product of driving axle housing flange head.Its shortcoming one is high to the size tolerance requirements of workpiece preorder turning position location, has increased difficulty of processing and processing cost; The 2nd, under the high tolerance requirement, carry out turning in enormous quantities processing, will inevitably occur slight overproof frequently, this can cause workpiece to put less than in the frock or be put into and be difficult on the frock take off, and the lifting workpiece difficulty has a strong impact on production efficiency; The 3rd, need constantly carry out frock during processing different model product and remodel, influence production efficiency.
The purpose of summary of the invention the utility model provides a kind of driving axle housing flange head four hole drill accurate positioning device; This positioner is to propose a solution to the problem that exists in the background technology, has that structural design is easy, machining accuracy is high, the efficient advantages of higher.
The purpose of the utility model realizes through following technical scheme: a kind of driving axle housing flange head four hole drill accurate positioning device; It is characterized in that comprising riser, upper plate, location guide, drill bit, drill bushing, compression leg, go up positioning pedestal, spring and taper, angle backstay, coarse positioning post, middle slide plate and oil cylinder; Respectively there is a location guide to fix in the both sides of whole device; Four compression legs of upper plate are at Corner Strapped; And drill bushing and last positioning pedestal are installed, and middle slide plate is provided with endoporus coarse positioning post and angle positioner.
Riser described in the technique scheme and location guide are two.
Compression leg described in the technique scheme, drill bushing, drill bit, spring and taper are four.
The basic ideas of technique scheme are that device is divided into three layers up and down; Four compression legs of upper plate are at Corner Strapped; Respectively adding a location guide in the both sides of whole device fixes; Place work piece on the middle slide plate, bottom is used as power and can be moved up and down along location guide by oil cylinder, and endoporus coarse positioning post and angle positioner are arranged on the middle slide plate.
The advantage of this driving axle housing flange head four hole drill accurate positioning device has: 1, project organization is simple, and is easy to use; 2, improve the precision and the efficient of processing.
Description of drawings Fig. 1 is the structural representation (profile) of the utility model.
Among the figure, riser (1), upper plate (2), location guide (3), drill bit (4), drill bushing (5), compression leg (6), last positioning pedestal (7), spring and taper (8), angle backstay (9), coarse positioning post (10), middle slide plate (11) and oil cylinder (12).
The specific embodiment is described further the utility model below in conjunction with accompanying drawing and embodiment.
In the present embodiment; Device has three layers up and down; Respectively there is a location guide (3) fixing in the both sides of whole device; (2) four compression legs of upper plate (6) are at Corner Strapped, and four drill bushings (5) and drill bit (6) are installed and go up positioning pedestal (7), and middle slide plate (11) is provided with endoporus coarse positioning post (10) and angle backstay (9).For reducing, use the big chamfering of dead eye instead and make benchmark the too high requirement of preorder position location machining accuracy.Convenient for lifting workpiece, reduce the number of times of remodeling, adopt workpiece small end endoporus to center roughly, side direction screw rod adjustable angle is to the location.Then, oil cylinder (12) is gone up automatically in top middle slide plate (11) process and is supportted the fine positioning that rises at the big chamfering of dead eye place, and last oil cylinder rises the top and puts in place the workpiece jam-packed.
The workpiece small end is put in the coarse positioning post (10), carries out coarse positioning, circumferentially turning of work piece; With angle backstay (9), carry out the angle location, oil cylinder (12) starts up; Middle slide plate (11) is up along 2 location guides (3), the big chamfering in up medi-spring and taper (8) contact bearing hole, and spring is begun compression; Taper one end moves with spring, the other end along the big chamfering of workpiece automatically with workpiece centering center; Last workpiece large end face liter is pushed up compression leg (6) and is gone up jam-packed, and last, device starts, and four drill bits (4) are realized accurately processing along four drill bushings (5) feeding simultaneously.
Test shows that this accurate positioning device can make flange head four hole locations≤∮ 0.2, and the clamping time average has shortened 2/3 than original device, and the endoporus chi has and becomes but the constant difference lane workpiece of four hole dimensions also need not have been remodeled.
