Description

Technical Field

[0001] The invention discloses a processing device and a control process for vehicle accessories based on profiled steel balls. Background Art

[0002] The anti-lock braking system is referred to as ABS. Its function is to automatically control the braking force of the brakes when the car brakes, so that the wheels are not locked and are in a state of rolling and sliding (slip rate is about 20%), so as to ensure that the adhesion between the wheels and the ground is at the maximum.

[0003] The anti-lock braking system can improve the safety factor of emergency braking of vehicles while driving. In other words, when a car without ABS is in an emergency, the tires are prone to lock, that is, the steering wheel cannot turn, which increases the risk factor and can easily lead to serious consequences.

[0004] Single-channel ABS generally controls both rear wheels together according to the low-selection principle. Single-channel ABS cannot fully utilize the adhesion of the two rear wheels, so the braking distance may not be significantly shortened. In addition, the front wheel brakes are not controlled, and the front wheels will still lock during braking, so the steering control ability is not improved. However, since the two rear wheels will not lock during braking, the directional stability during braking can be significantly improved, which is a major advantage in terms of safety. At the same time, it has the advantages of simple structure and low cost, so it is widely used in light trucks.

[0005] During braking, ABS can quickly determine the locked state of the wheel based on the speed signal from each wheel speed sensor, close the normally open input solenoid valve on the wheel that starts to lock, and keep the braking force unchanged. If the wheel continues to lock, the normally closed output solenoid valve is opened, and the brake pressure on this wheel moves down rapidly due to the pipeline directly connected to the brake fluid storage tank, preventing the wheel from being completely locked due to excessive braking force. Then keep the braking state at the optimal point (slip rate S is 20%), the braking effect is the best, and driving is the safest.

[0006] The brake fluid in the front chamber of the master brake cylinder is dynamic pressure brake fluid, which pushes the reaction sleeve to move to the right, and the reaction sleeve pushes the booster piston to move the brake pedal push rod to the right. Therefore, when ABS is working, the driver can feel the vibration of the pedal and hear some noise.

[0007] After the car slows down, once the ABS computer detects that the wheel lock state disappears, it will close the main control valve, so that the system can work under normal braking state. If the pressure of the accumulator drops below the safety limit, the red brake fault indicator light and the amber ABS fault indicator light will light up. In this case, the driver needs to use a greater force to brake the front and rear wheels in a deep pedal-type braking method to effectively brake the front and rear wheels.

[0008] The ABS system has multiple parts, among which the parts for hydraulic adjustment have a through hole in the middle for passing hydraulic oil, and a seal is blocked on the through hole. In order to ensure the sealing, the edge of the through hole will be processed so that the seal can better seal the through hole. However, in the prior art, a special tool is generally used to process the edge of the through hole so that the edge of the through hole and the seal can be in close contact. However, after processing by the existing tool, the edge of the through hole cannot be completely matched with the seal. The seal contacts the edge of the through hole only in a line, and the contact area is too small, the sealing is insufficient, and the performance of the ABS is affected. In addition, the cost of the tool used for processing is high, and the tool itself is easily damaged due to structural problems, so the cost of repair and replacement is also high. Summary of the invention

[0009] The purpose of the present invention is to solve the above deficiencies in the prior art and to provide a processing device and a control process for automotive accessories based on profiled steel balls.

[0010] A processing device for automotive accessories based on profiled steel balls, comprising a tool part, a fixture part, a workpiece to be processed and a sealing part;

[0013] The working principle of the present invention is as follows: a profiling steel bead-shaped cutter head with the same shape and specification as the seal is used to process the edge of the through hole on the workpiece to be processed, so that the processed surface formed after the edge of the through hole is matched with the seal, thereby maximizing the contact area between the seal and the through hole opening.

[0014] In order to adapt to different processing requirements, the seal and the cutter head include different specifications and shapes.

[0015] In order to ensure the lifting and lowering of the tool part, the lifting mechanism is a cylinder.

[0016] For the convenience of processing, a motor is arranged in the mounting seat, and the motor is connected to the tool. The rotation of the motor drives the tool to rotate, and the edge of the through hole is processed by grinding using the rotation force.

[0017] In order to facilitate the processing of multiple workpieces to be processed and improve the processing efficiency, a groove is provided in the bottom center of the mounting plate, a ball bearing is provided in the groove, the inner wall of the ball bearing is sleeved on the positioning column, the positioning column is cylindrical, and the positioning column is fixed on the base; a plurality of clamps are provided on the mounting plate, the clamps are distributed around the center circumference of the mounting plate, and the distance between the clamps and the center of the mounting plate is a predetermined distance.

Bolts are provided in the through holes, and the bolts are used to fix the fixture seat on the mounting plate.

[0022] After the inspection is completed, the pressure inside the workpiece is released, and the workpieces that meet the requirements are recycled, while the workpieces that do not meet the requirements are processed.

[0023] In order to ensure that it can accurately judge whether the workpiece to be processed meets the requirements after processing, the airtightness detector also includes inflation and pressure maintaining work. The inflation work is to inflate the interior of the workpiece to be processed. When the air pressure value inside the workpiece to be processed reaches a predetermined value, the inflation will be stopped and the pressure maintaining work will be performed. The pressure maintaining work is to stop inflating the interior of the workpiece to be processed and monitor the air pressure value inside the workpiece to be processed in real time.

[0027] The fixture part distributes multiple fixtures on the circumference of the mounting plate. When one workpiece is completed, the next workpiece can be processed by simply rotating the mounting plate. Each fixture is numbered to distinguish it, which improves the processing efficiency.
