Description
Technical field
The utility model relates to auto parts and components processing tool field, in particular to a kind of processing tool of preceding leading arm.
Background technique
Suspension is all force transmission connections between the vehicle frame (or monocoque body) of automobile and vehicle bridge (or wheel)
General name, effect are that transmitting acts on power between wheel and vehicle frame and power is turned round, and buffer by uneven road surface be transmitted to vehicle frame or
The impact force of vehicle body, and shaken caused by reducing thus, to guarantee that automobile can be travelled smoothly.
Automobile is in motion due to the variation of load and road surface, it is desirable that suspension stiffness is with variation.Car requires on good road
Upper reduction bodywork height improves speed traveling；Bodywork height is improved on bad road, increases handling capacity, thus requires vehicle body height
It spends adjustable with requirement.Air spring type rigid axle suspension can satisfy such requirement.
It is made of compressor, gas receiver, levelling valve, air spring, control-rod etc., in addition there are dampers, guiding
Arm, stabilizer bar etc..Air spring is fixed between vehicle frame (body) and vehicle bridge, levelling valve is fixed on vehicle body, wherein
The end of piston rod and the transverse arm of control-rod are hinged, and the other end of transverse arm is again hinged with control-rod, and the midfoot support of transverse arm is in sky
The lower end on gas spring top, control-rod is fixed in vehicle bridge.It forms and links together by the road between each component of air spring.
The high pressure gas that compressor generates enters gas receiver through oil water separator and pressure regulator, passes through again after coming out from gas receiver empty
Air cleaner entry altitude control valve, the gas flowed out from levelling valve flow into air accumulator after air cleaner, storage
Gas tank is communicated with the air spring on each wheel, thus in each air spring gas pressure with aeration quantity increase pressure liter
Height, while vehicle body being lifted until the piston in levelling valve blocks the inflating port inflated into air accumulator.As
Elastic element air spring can will act on the shock loading on wheel from road surface, give when transmitting through vehicle bridge to vehicle body
It mitigates.Furthermore air suspension can also realize that bodywork height automatically adjusts.Piston is located at inflating port and puts in levelling valve
Position between port, the gas from gas receiver is inflated to air accumulator and air spring, and raises bodywork height.Work as piston
Inflating port upper position is in levelling valve, the gas in air spring flows back into gas vent through inflating port and enters greatly
Gas, air pressure decline in air spring, then bodywork height also declines.And control-rod and transverse arm thereon determine piston in height
Position in control valve.
The structure of leading arm is as shown in Figure 1 comprising rectangular shaped.It is difficult to accomplish one in leading arm vertical angle process
Secondary property is just processed into 90 degree.Although the tooling at processing right angle can theoretically process right angle, since material can be sprung back, cause to add
Degree after work is less than 90 degree.
Utility model content
The purpose of the utility model is to provide a kind of preceding leading arm processing tools, being capable of good progress right angle processing.
In order to solve the above technical problems, the utility model is realized as follows:
A kind of preceding leading arm processing tool, including upper plate, right fillet molded part connecting rod, two fillet molded parts, a left sides
Fillet molded part connecting rod, lower plate and lower plate roller, left fillet molded part connecting rod is connected with lower plate and vertical, the right side
Fillet molded part connecting rod is connected and vertical with upper plate, and two fillet molded parts are rotatably connected on right fillet molded part respectively
The end of connecting rod, left fillet molded part connecting rod, three lower plate rollers are embedded in lower plate, and three lower plate rollers
It can freely roll, upper plate is movable part, and lower plate is fixing piece；The radius ratio workpiece to be processed and circle of two fillet molded parts
The radius of the contact surface of angle molded part is big, and the radius of the fillet molded part connected in left fillet molded part connecting rod is greater than right circle
The radius of the fillet molded part connected in the molded part connecting rod of angle.
The good effect of the utility model is: a kind of processing tool of preceding leading arm of the utility model is due to using as above
Structure, therefore right-angle structure can be disposably processed, it processes or does over again without repeating, therefore substantially increase production efficiency.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the leading arm of the utility model.
Fig. 2 is a kind of structural schematic diagram of preceding leading arm processing tool of the utility model.
Specific embodiment
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
As shown in Fig. 2, a kind of preceding leading arm processing tool of the utility model one embodiment includes: upper plate 1, right circle
Angle molded part connecting rod 2, fillet molded part 4, left fillet molded part connecting rod 5, lower plate 6 and lower plate roller 7.Left fillet at
Type part connecting rod 5 is connected and vertical with lower plate 6, and right fillet molded part connecting rod 2 is connected and vertical with upper plate 1, and two
A fillet molded part 4 is rotatably connected on the end of right fillet molded part connecting rod 2, left fillet molded part connecting rod 5 respectively.Three
Lower plate roller 7 is embedded in 6 lower plates, and three lower plate rollers can be rolled freely.Upper plate is movable part 1, lower plate 6
For fixing piece.
The radius ratio workpiece to be processed and the radius of the contact surface of fillet molded part of two fillet molded parts 4 are big, and Zuo Yuan
The radius of the fillet molded part 4 connected in angle molded part connecting rod 5 be greater than in right fillet molded part connecting rod 2 fillet that connects at
The radius of type part 4.Lower plate roller 7 is from close to left fillet molded part connecting rod 5 to separate left round 5 direction of angle-piece connecting rod
Radius increases, while the variable quantity increased is between 1-5mm.
In workpieces processing 3, as long as workpiece 3 is placed between two 4 fillet molded parts, then 1 upper plate is moved downward,
Workpiece is bent by 4 fillet molded parts, because of 4 radius of fillet molded part on the right of the radius ratio of the fillet molded part 4 on the left side
It is larger, cause the vertical plane of workpiece 3 after processing a little to tilt to the right, the vertical plane of workpiece can be sprung back after workpiece 3 removes
It is some, just arrive vertical state.Lower plate roller 7 when workpieces processing 3 on lower plate 6 can be contacted with workpiece 3, with workpiece 3
Deformation and it is mobile with the contact surface of lower plate 6 when lower plate roller 7 play the role of reducing friction.
A kind of preceding leading arm processing tool of the utility model can be processed disposably due to using structure as above
Right-angle structure is processed or is done over again without repeating, therefore substantially increases production efficiency.
The utility model is not limited to above-mentioned preferred forms, anyone can obtain under the enlightenment of the utility model
Other various forms of products, however, make any variation in its shape or structure, it is all with identical as the utility model
Or similar technical solution, it all falls within the protection scope of the utility model.
