Description
Technical Field
The invention relates to the field of automobile part processing tools, in particular to a front guide arm processing tool.
Background
The suspension is a general term for all force-transmitting connecting devices between a frame (or a load-bearing vehicle body) and an axle (or a wheel) of an automobile, and has the functions of transmitting force and torque acting between the wheel and the frame, buffering impact force transmitted to the frame or the vehicle body from an uneven road surface, and reducing vibration caused by the impact force so as to ensure that the automobile can run smoothly.
When the automobile runs, the rigidity of the suspension is required to change along with the change of the load and the road surface. The car requires to reduce the height of the car body on a good road and improve the speed of the car; the height of the vehicle body is increased on a bad road, and the passing capacity is increased, so that the height of the vehicle body is required to be adjustable according to the use requirement. Air spring type non-independent suspensions can meet such requirements.
The air compressor comprises an air compressor, an air storage cylinder, a height control valve, an air spring, a control rod and the like, and further comprises a shock absorber, a guide arm, a transverse stabilizer bar and the like. The air spring is fixed between the vehicle frame (body) and the vehicle axle, the height control valve is fixed on the vehicle body, the tail end of the piston rod is hinged with the cross arm of the control rod, the other end of the cross arm is hinged with the control rod, the middle part of the cross arm is supported on the upper part of the air spring, and the lower end of the control rod is fixed on the vehicle axle. All the components forming the air spring are connected together through pipelines. High-pressure gas generated by the gas compressor enters the gas storage cylinder through the oil-water separator and the pressure regulator, the high-pressure gas flows out of the gas storage cylinder and then enters the height control valve through the air filter, the gas flowing out of the height control valve flows into the gas storage tank through the air filter, and the gas storage tank is communicated with the air springs on the wheels, so that the pressure of the gas in the air springs is increased along with the increase of the inflation quantity, and simultaneously, the vehicle body is lifted until a piston in the height control valve blocks an inflation port for inflating the gas storage tank. The air spring as an elastic member can reduce an impact load applied to the wheel from the road surface when the impact load is transmitted to the vehicle body through the axle. In addition, the air suspension can also realize automatic adjustment of the height of the vehicle body. The piston is positioned between the inflation port and the deflation port in the height control valve, and the air from the air storage cylinder inflates the air storage cylinder and the air spring and raises the height of the vehicle body. When the piston is positioned at the upper part of the inflation inlet in the height control valve, the air in the air spring flows back to the air release port through the inflation inlet to enter the atmosphere, the air pressure in the air spring is reduced, and then the height of the vehicle body is also reduced. And the control rod and its cross arm determine the position of the piston within the height control valve.
The guide arm is constructed as shown in fig. 1, and includes a right-angled shape. The guide arm is difficult to be processed into 90 degrees at one time in the process of processing the vertical angle of the guide arm. Although the tool for machining the right angle can theoretically machine the right angle, the degree after machining is smaller than 90 degrees due to the fact that materials can rebound.
Disclosure of Invention
The invention aims to provide a front guide arm machining tool which can be used for machining right angles well.
In order to solve the technical problem, the invention is realized as follows:
a front guide arm machining tool comprises an upper base plate, a right fillet forming piece connecting rod, two fillet forming pieces, a left fillet forming piece connecting rod, a lower base plate and a lower base plate roller, wherein the left fillet forming piece connecting rod is connected with and perpendicular to the lower base plate; the radius of two fillet formed parts is greater than the radius of the contact surface of waiting to process work piece and fillet formed part, and the radius of the fillet formed part of connecting on the left fillet formed part connecting rod is greater than the radius of the fillet formed part of connecting on the right fillet formed part connecting rod.
The invention has the positive effects that: the processing tool for the front guide arm adopts the structure, so that a right-angle structure can be processed at one time, repeated processing or reworking is not needed, and the production efficiency is greatly improved.
Drawings
Fig. 1 is a schematic structural view of a guide arm of the present invention.
Fig. 2 is a schematic structural diagram of a front guide arm machining tool of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
As shown in fig. 2, a front guide arm machining tool according to an embodiment of the present invention includes: the device comprises an upper bottom plate 1, a right fillet forming part connecting rod 2, a fillet forming part 4, a left fillet forming part connecting rod 5, a lower bottom plate 6 and a lower bottom plate roller 7. Left fillet formed part connecting rod 5 is connected and perpendicular with lower plate 6, and right fillet formed part connecting rod 2 is connected and perpendicular with upper plate 1, and two fillet formed parts 4 rotate respectively and are connected at the tip of right fillet formed part connecting rod 2, left fillet formed part connecting rod 5. Three lower base plate rollers 7 are embedded in the lower base plate 6, and the three lower base plate rollers can roll freely. The upper base plate is a movable part 1, and the lower base plate 6 is a fixed part.
The radius of two fillet formed part 4 is greater than the radius of the contact surface of waiting to process work piece and fillet formed part, and the radius of the fillet formed part 4 of connecting on the left fillet formed part connecting rod 5 is greater than the radius of the fillet formed part 4 of connecting on the right fillet formed part connecting rod 2. The radius of the lower bottom plate roller 7 is increased from the direction close to the left fillet profile connecting rod 5 to the direction far away from the left fillet profile connecting rod 5, and the increased variation is between 1 mm and 5 mm.
When processing work piece 3, as long as put work piece 3 between two 4 fillet formed parts, then 1 upper plate downstream, through 4 fillet formed parts with the work piece bending, because the radius of fillet formed part 4 on the left side is greater than the radius of fillet formed part 4 on the right side some, cause the vertical face of processing back work piece 3 to have some to the slope on the right, wait that the vertical face of work piece 3 back work piece of removing can kick-back some, just in time to vertical state. The lower plate rollers 7 on the lower plate 6 contact the workpiece 3 when the workpiece 3 is machined, and the lower plate rollers 7 play a role of reducing friction when the contact surface with the lower plate 6 moves along with the deformation of the workpiece 3.
Due to the adoption of the structure, the front guide arm machining tool can machine a right-angle structure at one time without repeated machining or reworking, so that the production efficiency is greatly improved.
The present invention is not limited to the above-mentioned preferred embodiments, and any other products in various forms can be obtained by anyone in the light of the present invention, but any changes in the shape or structure thereof, which have the same or similar technical solutions as the present invention, fall within the protection scope of the present invention.
