Description

Technical Field

[0001] The invention relates to the technical field of automobile brake processing and production, and in particular to a grinding device and a grinding method for automobile brake processing. Background Art

[0002] Automobile brakes are the braking devices of automobiles. Brakes used in automobiles are almost all friction type, which can be divided into two categories: drum type and disc type. The rotating element in the friction pair of drum brakes is the brake drum, whose working surface is a cylindrical surface; the rotating element of disc brakes is the rotating brake disc, whose end surface is the working surface.

[0003] During the production and processing of automobile brakes, the surface of the automobile brakes needs to be polished using a grinding wheel in a polishing equipment. The position between the grinding wheel and the disc wheel in the polishing equipment is usually very important and absolute parallelism needs to be maintained. If the two are not parallel, the grinding wheel may deviate or shake when rotating. In existing polishing equipment, visual inspection by staff is usually used to determine whether there is a large deviation between the grinding wheel and the disc wheel. However, a small deviation cannot be determined by the naked eye, which will result in uneven polishing of the workpiece surface and affect the quality. In addition, in existing polishing equipment, usually only one grinding wheel head is set to polish the automobile brakes, and multiple polishing of the automobile brakes cannot be performed, thereby reducing the overall processing efficiency of the automobile brakes.

The latter two beams are projected onto the contact point between the disc wheel and the fine grinding wheel, and then the two beams are reflected and returned to the laser transmitter again; Step S3, after the two light beams return to the laser transmitter, they merge to generate interference phenomenon. At this time, the two reflected light beam paths are received by the laser receiving board, and the reflected light is displayed on the laser receiving board. By observing the interference phenomenon reflected on the laser receiving board, whether interference fringes are generated, if the interference fringes are parallel and symmetrical, it means that the parallelism between the disk wheel and the fine grinding wheel is good, if the interference fringes are misplaced or deformed, offset occurs, triggering the displacement sensor, and then driving the three-primary color tube and buzzer in the laser driving circuit to run, at this time the three-primary color tube flashes, and buzzer B makes a sound, indicating that there is a parallelism error between the disk wheel and the fine grinding wheel, and similarly, the parallelism between the disk wheel and the coarse grinding wheel can be judged; Step S4, according to the interference phenomenon, after adjusting the positional relationship between the disc wheel and the fine grinding wheel and the coarse grinding wheel, start the servo motor 1 and the servo motor 2 in sequence, so that the support plate 2 moves to the position of the same axis as the fixed shaft, and the support plate 3 moves to the side of the fixed shaft, and adjusts and selects the most suitable grinding distance between the vehicle brake; Step S5, after the adjustment is completed, the electric cylinder above the rough grinding wheel is started to drive the connecting vertical plate to descend until the rough grinding wheel contacts the surface of the automobile brake, and then the rough grinding wheel is driven to rotate by the driving motor 2, so that the rough grinding wheel roughly grinds the surface of the automobile brake to remove uneven or excessively thick parts on the automobile brake and form a preliminary shape; Step S6, after the rough grinding of the automobile brake is completed, the electric cylinder above the fine grinding wheel drives the connecting vertical plate to descend, so that the fine grinding wheel contacts the surface of the automobile brake, and then the fine grinding wheel is driven to rotate by the driving motor 2, so that the fine grinding wheel finely grinds the surface of the automobile brake to provide a smooth and flat surface quality.

[0013] The beneficial effects of the present invention are: The automobile brake is clamped and fixed on the support table through the clamping assembly. By starting the laser parallelism meter and the laser transmitter, the laser transmitter emits a laser beam through the transmitter head, which is then divided into two beams by the beam splitter and projected onto the contact points between the disc wheel and the fine grinding wheel and the coarse grinding wheel.

[0029] In the present embodiment, specifically, when it is necessary to process and grind the surface of the automobile brake, first, insert the hole in the middle of the automobile brake into the fixed shaft 7, and insert the side of the automobile brake into the clamping groove 804, then pull the clamping plate 801 upward and oppositely, so that the clamping plate 801 clamps and fixes the automobile brake, and then start the servo motor 902. When the servo motor 902 is running, it drives the connecting screw 903 to rotate. When the connecting screw 903 rotates, the sliding block 904 slides. The sliding of the sliding block 904 drives the support plate 2 10 to move. When the support plate 2 10 moves, it drives the disc wheel 5 and the fine grinding wheel 501 to move to a position perpendicular to the laser parallelism meter 203. Furthermore, after the position and angle between the disk wheel 5 and the laser parallelism meter 203 are adjusted, the laser parallelism meter 203 is started. After the laser parallelism meter 203 is running, the laser emitter 204 is immediately started. The laser emitter 204 passes through the transmitter head 205 and drives the laser driving circuit to run. When the current enters the laser driving circuit and passes through the converter circuit composed of the transistor Q1 and the step-up transformer T2, due to the effect of the capacitor C2 and the magnetic bead filter T1, it will be briefly turned on before saturation, until the voltage across the capacitor C2 increases to make the base of the transistor Q1 reverse biased. At this time, the transistor Q1 is cut off, and the magnetic field of the coil in the step-up transformer T2 is weakened. Subsequently, an increased voltage is generated at a specific phase of the secondary of the step-up transformer T2, and at the same time, the secondary of the step-up transformer T2 is The increased square wave voltage is rectified by the rectifier diode D1, and then the current is stored through the capacitor C3 to balance the current energy supply and demand of the circuit and ensure the stable output of the subsequent current. Then the current flows through the resistor R5 through the timer I1, and the timer I1 outputs a trigger pulse at a fixed time. At this time, the timing of the timer I1 can be controlled by the resistor R8 and the capacitor C6. The output trigger pulse is output through the capacitor C4, and then a reverse overshoot is generated, and it is clamped by the clamping diode D2 and sent to the thyristor S1. Then the thyristor S1 is turned on, so that the current flows through the laser diode D3. When the current flows through the laser diode D3, it is discharged and then a current pulse is generated. At this time, the current pulse is turned on and off by the thyristor S1 to control the discharge of the capacitor C3, and then the laser diode D3 is prompted to emit light. At this time, the switch S is turned off; When the laser diode D3 emits light, it prompts the transmitter head 205 to emit a laser beam, which is divided into two beams after passing through the displacement sensor 207 and the beam splitter 208. The two beams are then projected onto the contact point between the disk wheel 5 and the fine grinding wheel 501. After being reflected by the contact point, the two beams pass through the displacement sensor 207 and then pass through the transmitter head 205 again to return to the laser transmitter 204. When the two laser beams return to the laser transmitter 204 and merge, interference will occur. At this time, the two reflected beam paths are received by the laser receiving board 209, and the reflected light is displayed on the laser receiving board 209. The displacement sensor 207 monitors the offset distance of the reflected light, and observes the interference phenomenon reflected on the laser receiving board 209 to see if interference fringes are generated. If the interference fringes are parallel and symmetrical, it means that the parallelism between the disk wheel 5 and the fine grinding wheel 501 is good. If the interference fringes are misplaced or deformed and offset, the displacement sensor 207 detects that the light position is offset. When the optical path is converted into an electrical signal, the trigger switch S is closed, and the current flows through the three-primary color tube RGB through the displacement sensor 207. At this time, the three-primary color tube RGB flashes. When the current flows through the transistor Q2 through the resistor R7, the transistor Q2 amplifies the current passing through its base, and then outputs a larger current at the collector. The current is amplified by the transistor Q2 and flows through the collector through the buzzer BUZ. At this time, the buzzer BUZ makes a sound prompt, thereby reminding the staff that there is a parallelism error between the disk wheel 5 and the fine grinding wheel 501. Then, the position between the disk wheel 5 and the fine grinding wheel 501 can be adjusted according to the interference phenomenon, so that the interference fringes are restored to parallelism and symmetry, thereby maintaining an absolute parallel relationship between the disk wheel 5 and the fine grinding wheel 501. After adjusting the parallelism of the disk wheel 5 and the fine grinding wheel 501, the coarse grinding wheel 502 is moved to a position perpendicular to the laser parallelism meter 203, and the above steps are repeated. Similarly, the parallelism relationship between the disk wheel 5 and the coarse grinding wheel 502 can be measured and adjusted; Further, after the positional relationship between the disc wheel 5 and the fine grinding wheel 501 and the coarse grinding wheel 502 is adjusted, the servo motor 1 902 and the servo motor 2 1012 are started in sequence. The servo motor 1 902 drives the support plate 2 10 to move to a position on the same axis as the fixed automobile brake. When the servo motor 2 1012 is running, it drives the connecting screw 2 1013 to rotate. When the connecting screw 2 1013 rotates, it drives the sliding block 2 1014 to slide along the track of the supporting slide rail 2 1011. When the sliding block 2 1014 slides, The support plate 3 11 is driven to move, and the support plate 3 11 moves, which drives the connecting plate 4 to move. When the connecting plate 4 moves, it drives the fine grinding wheel 501 and the coarse grinding wheel 502 to move to the side of the automobile brake. At the same time, the most suitable grinding distance between the automobile brake and the vehicle brake is adjusted and selected according to the position of the automobile brake. After the adjustment is completed, the electric cylinder 1102 above the coarse grinding wheel 502 is first started to drive the connecting block 1103 and the connecting vertical plate 1104 to descend along the track of the support slide rail 3 1101 until the coarse grinding wheel 502 and the automobile brake are aligned. The surface of the vehicle brake is contacted, and then the rough grinding wheel 502 is driven to rotate by the driving motor 2 1202. At this time, the driving motor 1 601 is started. When the driving motor 1 601 is running, it drives the fixed shaft 7 to rotate. When the fixed shaft 7 rotates, it drives the automobile brake to rotate. Therefore, when the automobile brake rotates, the rough grinding wheel 502 performs uniform and comprehensive preliminary grinding on the surface of the automobile brake, thereby removing the uneven or too thick parts on the automobile brake, forming a preliminary shape, and the automobile brake can be quickly trimmed. After the preliminary grinding of the automobile brake is completed, the electric cylinder 1102 above the fine grinding wheel 501 drives the connecting vertical plate 1104 to descend, so that the fine grinding wheel 501 contacts the surface of the automobile brake, and then the driving motor 2 1202 drives the fine grinding wheel 501 to rotate. When the fine grinding wheel 501 rotates, the surface of the automobile brake can be further finely ground to provide a smooth and flat surface quality, remove the traces left on the rough surface of the automobile brake after the preliminary grinding, provide higher surface accuracy and finish, and further improve the quality of automobile brake processing and grinding.

[0030] Embodiment 2 Reference Figure 2-8 Based on the second embodiment, a technical solution of a grinding method for automobile brake processing is provided, comprising the following steps: Step S1, insert the through hole in the middle of the automobile brake into the fixed shaft 7, insert the side edges of the automobile brake into the clamping groove 804 in sequence, and use the clamping assembly to clamp and fix the automobile brake; Step S2, move the support plate 2 10 and adjust the position and angle of the disk wheel 5 and the laser parallelism meter 203 to ensure that the laser beam can irradiate the contact point between the disk wheel 5 and the fine grinding wheel 501, then start the laser parallelism meter 203, and then start the laser emitter 204 after the laser parallelism meter 203 is running. The laser emitter 204 emits a laser beam through the emission head 205, and the beam is divided into two beams after passing through the beam splitter 208. The latter two beams are projected onto the contact point between the disk wheel 5 and the fine grinding wheel 501, and then the two beams are reflected and returned to the laser emitter 204 again; Step S3, after the two light beams return to the laser transmitter 204, they merge to generate interference phenomenon. At this time, the two reflected light beam paths are received by the laser receiving board 209, and the reflected light is displayed on the laser receiving board 209. By observing the interference phenomenon reflected on the laser receiving board 209, whether interference fringes are generated, if the interference fringes are parallel and symmetrical, it means that the parallelism between the disk wheel 5 and the fine grinding wheel 501 is good. If the interference fringes are misplaced or deformed, an offset is generated, triggering the displacement sensor 207, and then driving the three-primary color tube and the buzzer in the laser driving circuit to run. At this time, the three-primary color tube RGB flashes, and the buzzer BUZ makes a sound, indicating that there is a parallelism error between the disk wheel 5 and the fine grinding wheel 501.
