Description

Technical Field

[0001] The utility model relates to the technical field of metal parts surface treatment equipment, in particular to an automatic polishing system for a motorcycle brake disc. Background Art

[0002] After the motorcycle brake disc is manufactured, it is usually necessary to polish and clean its surface to remove machining marks, surface oxide layer or metal chips, so as to obtain better appearance and performance. Traditional polishing, cleaning and drying are mostly dispersed processes, with frequent manual operations and low efficiency. The transfer between workpieces is also prone to collision or secondary surface contamination.

[0003] To solve the above problems, some existing automated equipment can combine polishing and cleaning, but there are still deficiencies in efficiency, quality and subsequent drying. For example, some equipment only realizes a single polishing or cleaning process, which requires manual transfer to the drying station; some equipment, although realizing multi-process linkage, lacks flexibility in electrical control and time sequence, and cannot adapt to different brake disc specifications or production capacity requirements.

[0004] Based on this, the present application provides an automatic polishing and drying system for motorcycle brake discs, which, through the cooperation of multiple motors and time relays, completes the polishing, flushing and centrifugal drying of the brake discs under the control of a set of circuits, and can be programmed to adjust according to different production needs. Utility Model Content

[0005] The utility model aims to provide an automatic polishing system for motorcycle brake discs. The automatic polishing system for motorcycle brake discs integrates polishing, cleaning and drying processes, improves production efficiency, and reduces manual participation and workpiece damage.

[0006] The above technical objectives of the utility model are achieved through the following technical solutions:

[0015] The automatic polishing system for motorcycle brake discs realizes the integration of polishing, cleaning and drying processes through circuit design. The system adopts the collaborative working mode of three motors. Motor M1 controls the grinding of the polishing wheel, motor M2 drives the rotation of the turntable, and motor M3 controls the drying of the fan. The system realizes full automation through the cooperation of four functional circuits (polishing wheel, solenoid valve, turntable and fan control circuit). The control circuit ensures the precise connection between processes through the linkage control of multiple groups of time relays: during the polishing process, the solenoid valve provides cooling water, and after the polishing is completed, the cleaning continues. Then the turntable rotates at high speed to dry, and finally the fan is started to complete the drying. Through the precise control of the time relay, each process is automatically switched without manual intervention, which not only improves production efficiency and reduces labor costs, but also ensures the consistency of product quality through programmed processing, while avoiding secondary contamination of workpieces during transportation.

[0019] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0020] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0021] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0022] like Figure 1 As shown, a motorcycle brake disc automatic polishing system includes three-phase power supplies L1, L2, and L3. The three-phase power supplies L1, L2, and L3 are connected to an air switch QF. The air switch QF is connected to a power circuit and a control circuit.

[0023] The power circuit includes three three-phase motors, namely motor M1, motor M2, and motor M3. Among them, motor M1: polishing motor, drives the polishing wheel to grind and polish the surface of the brake disc; motor M2: turntable motor, drives the brake disc installed on the turntable to rotate and polish and dry the moisture; motor M3: fan motor, flows and outputs air to the brake disc for drying.

[0024] Motor M1, motor M2, motor M3 are connected to thermal relay FR1, thermal relay FR2, thermal relay FR3 respectively. If an abnormal situation such as overload, stalling, etc. occurs, the thermal relay will be activated to cut off the circuit.

[0025] The thermal relays FR1, FR2 and FR3 are connected to contactors KM1, KM2 and KM3 respectively. The contactors KM1, KM2 and KM3 are used to control the opening and closing of the motors M1, M2 and M3.

[0026] The control circuit includes a panel switch SB1. The panel switch SB1 switches states each time it is clicked. In the initial state, clicking the panel switch SB1 once energizes the control circuit.

[0027] The control circuit also includes a polishing wheel control circuit, a solenoid valve control circuit, a turntable control circuit and a fan control circuit.

[0028] The polishing wheel control circuit includes a thermal contactor FR1. The thermal contactor FR1 is connected to a normally closed switch KT1. The normally closed switch KT1 is connected to a relay KM1. At the same time, the normally closed switch KT1 is connected in parallel with a power-on delay time relay KT1. When the control circuit is energized, current flows through the thermal contactor FR1 and the normally closed switch KT1, so that the relay KM1 is energized, thereby controlling the contactor KM1 to close, and the motor M1 starts to work, so that the polishing wheel polishes the brake disc. At the same time, the time relay KT1 is energized to start timing. After the timing is over, the normally closed switch KT1 is disconnected, so that the relay KM1 is de-energized and the motor M1 stops.

[0029] The solenoid valve control circuit includes a normally closed switch KT2. The normally closed switch KT2 is connected to a solenoid valve EV. The solenoid valve EV is used to control the on and off of clean water. It opens when the solenoid valve EV is energized and closes when the power is off. At the same time, the normally closed switch KT2 is connected in parallel with a power-on delay time relay KT2. When the control circuit is energized, current flows through the normally closed switch KT2, so that the solenoid valve EV is energized, the solenoid valve EV opens, and clean water is output to the brake disc. At this time, the time relay KT2 is energized and the timing starts. When the timing ends, the normally closed switch KT2 is disconnected, causing the solenoid valve EV to lose power, and then no water is discharged.

[0030] Furthermore, the setting time of the time relay KT2 is greater than the setting time of the time relay KT1. During the polishing process, the water discharge plays a cooling role. After the polishing is completed, the water continues to discharge for a period of time to clean the brake disc.

[0031] The turntable control circuit includes a thermal contactor FR2. The thermal contactor FR2 is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a relay KM2. When the control circuit is powered on, current flows through the thermal contactor FR2 and the normally closed switch KT3, so that the relay KM2 is powered on, thereby closing the contactor KM2, the motor M2 works, and the turntable keeps rotating. At the end of the cleaning process, the turntable continues to rotate, which can throw some water off the brake disc.

[0032] The fan control circuit includes a thermal contactor FR3. The thermal contactor FR3 is connected to a normally open switch KT2. The normally open switch KT2 is connected to a normally closed switch KT3. The normally closed switch KT3 is connected to a relay KM3. At the same time, the normally closed switch KT3 is connected in parallel with a power-on delay time relay KT3. When the time relay KT2 is in timing contact, water is no longer discharged. At the same time, the normally open switch KT2 is closed, and current flows through the thermal contactor FR3, the normally open switch KT2, and the normally closed switch KT3, so that the relay KM3 is energized, the motor M3 works, and the moisture on the brake disc is blown dry.

[0033] In addition, when the timing of the time relay KT3 ends, each normally closed switch KT3 is disconnected, and the relay KM2 and the relay KM3 are both powered off, so that the turntable stops rotating and the fan stops running.

[0034] After the above process is completed, replace the brake disc and click the panel switch SB1 twice at the same time to recycle the above operation. The above process integrates polishing, cooling, cleaning and drying, thereby improving the production efficiency of the brake disc polishing process and reducing labor costs.

[0035] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
