Description

Technical Field

[0001] The utility model relates to the technical field of vehicle production auxiliary equipment, in particular to an automatic assembly device for a vehicle air release valve. Background Art

[0002] The bleed valve is a safety feature on vehicle hydraulic brakes. During vehicle hydraulic brake production, the bleed valve is installed and secured within the threaded mounting holes on the hydraulic brake's oil supply and return lines (the front and outer sides of the bleed valve are typically hexagonal for easy installation and removal). Currently, this is done by using a manual wrench or electric tightening tool to insert a sleeve around the outside of the bleed valve and then twisting it into the threaded holes on the oil supply and return lines. (The brake has two mounting holes on each side of the top for easy installation. The mounting holes are typically located similarly across different brake models, but the angles of the bleed valves vary.)

[0003] Although manual wrenches or electric tightening guns each have their own advantages and disadvantages and meet production needs to a certain extent, they are still subject to the following technical problems due to structural limitations. Specifically, before tightening the bleed valve, the brake needs to be manually fixed in a fixed position (after placing the brake between the two movable clamps in the fixed position, and then manually controlling or electrically clamping the brake) before operation can be performed. Subsequently, the staff is required to perform reverse operations to remove the processed brake. The above method will cause inconvenience to the staff and is not conducive to improving work efficiency. In addition, although the electric tightening gun does not require manual rotation of the sleeve, it brings convenience to the staff and reduces labor intensity to a certain extent. However, the staff still needs to hold the electric tightening gun to operate during the entire process, so there is still a problem of increasing the labor intensity of the staff and not being conducive to improving work efficiency. With the advancement of industrial technology, it has become a very mature technology to control the different working modes of one or more electrical devices (such as motors, solenoid valves, etc.) according to programming based on PLC or host computer, single-chip computer module (hereinafter referred to as control system). However, at present, there is no technology that can control the bleed valve of the electric tightening gun to automatically tighten the brake through the control system. Therefore, it is particularly necessary to provide a device based on the control system that can control the electric tightening gun to automatically fix the bleed valve. Utility Model Content

[0019] Figure 1 、 2As shown in Figures 3 and 4, this new model is based on a control system of a PLC or a host computer, a single-chip microcomputer module (this model adopts a PLC) and an electric tightening gun. Before first use, the staff will install the batch brakes with the bleed valve 8 as needed, and the installation angle of the bleed valve 8 (the staff will manually put the fixing holes 71 on both sides of the brake on the two top columns respectively). After turning the forward or reverse power switch S2 forward or backward, the rotating shaft of the motor reduction mechanism M2 will drive the driven wheel 53 to rotate clockwise or counterclockwise through the driving wheel 52 and the transmission belt 54, and then the shaft 43 will drive the rotating plate 55 and the electric tightening gun 1 to rotate clockwise or counterclockwise. When the front end sleeve of the electric tightening gun 1 is aligned and in a straight line with the bleed valve 8 of the brake 7, the forward or reverse power switch is turned off; after the staff turns the forward or reverse power switch S1 forward or backward, the motor of the electric linear slide M1 is energized, and its sliding block drives the electric tightening gun 1 to move left or right to the front side end of the brake and stop moving (the sleeve and the bleed valve installation position of the brake are in a straight line front and back). When the front end sleeve of the electric tightening gun 1 is aligned and in a straight line front and back with the bleed valve 8 of the brake 7, the forward or reverse power switch is turned off. The working process of this new type is as follows: (1) the staff puts the front end of a bleed valve 8 into the sleeve of the electric tightening gun, and the thread of the bleed valve 8 is located at the rear outer end of the sleeve. Then, the fixing holes 71 on both sides of the brake are respectively put on the two top pillars 64. The power switch of the PLC is turned on manually. The PLC controls the air inlet and exhaust solenoid valve DC1 at the upper end of the cylinder A62 to open the valve core for a period of time. In this way, the compressed air in the air compressor tank enters the upper end of the cylinder A62 through the air inlet of the air inlet and exhaust solenoid valve DC1 (the air at the lower end of the cylinder A62 is discharged through the exhaust port of the air inlet and exhaust solenoid valve DC2 at the lower end of the cylinder A). The piston rod of the cylinder A62 drives the pressure plate 63 downward (the linear bearing is the downward guide of the pressure plate), pressing the brake against the top pillar, and preparing for the subsequent screwing in of the bleed valve. (2) The PLC controls the solenoid valve DC3 at the front end of the cylinder 57 to be energized and the valve core is opened for a period of time. In this way, the compressed air in the air compressor tank enters the front end of the cylinder 57 through the air inlet of the air inlet and exhaust solenoid valve DC3 (the air at the rear end of the cylinder 57 is discharged through the exhaust port of the air inlet and exhaust solenoid valve DC4 at the rear end of the cylinder 57). The piston rod of the cylinder 57 drives the electric tightening gun 1 to move backward (the linear guide 56 plays a guiding role) and gradually approaches the installation position of the brake's air release valve. When the rear end of the air release valve 87 contacts the installation position, the PLC controls the electric tightening gun 1 to be energized and work for a period of time (the synchronous cylinder 57 continues to be energized and moves forward). The rotation of its sleeve will screw the rear end thread part of the air release valve 8 into the installation position of the brake's air release valve. After the air release valve is tightened, the electric tightening gun stops working.(3) The PLC controls the valve core of the air intake and exhaust solenoid valve DC4 at the rear end of the cylinder 57 to open for a period of time. In this way, the compressed air in the air compressor tank enters the rear end of the cylinder 57 through the air inlet of the air intake and exhaust solenoid valve DC4 (the air at the front end of the cylinder 57 is discharged through the exhaust port of the air intake and exhaust solenoid valve DC3 at the front end of the cylinder 57). The piston rod of the cylinder 57 drives the electric tightening gun 1 to move backward and gradually enlarge the installation position of the brake's air bleed valve, and then stops moving (with an interval of about 5 cm, to prepare for the next installation of the air bleed valve for the next brake). (4) During the time when the PLC controls the inlet and exhaust solenoid valve DC4 of the cylinder 57 to be energized synchronously, the PLC controls the inlet and exhaust solenoid valve DC2 at the lower end of the cylinder A62 to be energized and the valve core is opened for a period of time. In this way, the compressed air in the air compressor storage tank enters the lower end of the cylinder A62 through the inlet port of the inlet and exhaust solenoid valve DC2 (the air in the upper end of the cylinder A62 is discharged through the exhaust port of the inlet and exhaust solenoid valve DC1 at the upper end of the cylinder A62). The piston rod of the cylinder A62 drives the pressure plate 63 upward, and a certain distance (about 10 cm) is separated from the upper end of the brake pressure. The staff can remove the brake and complete the installation of the air release valve of a brake. The above process (1)-(4) is continuously circulated, and the air release valve can be continuously installed for the brake. This new model brings convenience to the staff and correspondingly improves work efficiency.
