Description

TECHNICAL FIELD

[0001] The utility model relates to a polishing workbench technical field especially pad polishing workbench. BACKGROUND

[0002] In the field of mechanical structural assembly, the precise processing of assembly gap plays a key role in ensuring the assembly quality and strength. Usually, to solve this problem, the way of adding pads for compensation is adopted, among which the assembly gap compensation pad is mostly a large-size thin-walled part, and its thickness varies more complexly. When processing such pads, many challenges are faced. Due to its own structural characteristics, the large-size thin-walled form makes it prone to deformation during processing, seriously affecting the size accuracy and flatness of the pad and other quality indicators. Meanwhile, the traditional robot automatic polishing process also faces some problems. The polishing operation produces a large amount of dust, which not only pollutes the working environment, but also threatens the health of the operators. At the same time, the heat generated by polishing is difficult to dissipate, which easily leads to deformation of the pad due to overheating, further reducing the quality of the pad, and even making it scrap, increasing the production time and material cost. The traditional robot automatic polishing dust removal method mainly integrates a dust collection device at the polishing end. However, it is found in practice that this way cannot effectively solve the dust problem, and there will still be a large amount of powder remaining in the air, which cannot completely purify the working environment. Moreover, this method cannot cool the pad, and the deformation risk of the pad always exists during long-time polishing, which is difficult to guarantee the processing accuracy and quality stability of the pad.

The vacuum adsorption part 2 is arranged on the support surface of the support table 1 and is used for adsorbing and fixing the gasket. The vacuum adsorption part 2 can generate uniform and strong adsorption force on the gasket by arranging a vacuum pump in the support table 1 or using the negative pressure air source of the factory building to perform vacuumization, so that the gasket can be kept stable during polishing. The vacuum adsorption part 2 can be a vacuum adsorption groove arranged in a single ring on the support table 1 or a vacuum adsorption hole arranged in an intermittent ring. In addition, the vacuum adsorption part 2 can also be a plurality of vacuum adsorption grooves arranged in a ring on the support table 1 and / or a plurality of vacuum adsorption holes arranged in an intermittent ring. In the present embodiment, the vacuum adsorption part 2 is a vacuum adsorption groove arranged in a ring on the support table 1. The surrounding part 3 is arranged on the support surface of the support table 1 and forms a cleaning space. The vacuum adsorption part 2 is located in the cleaning space surrounded by the surrounding part 3. The surrounding part 3 can effectively prevent the cooling liquid and polishing dust from splashing out and can also converge and guide the cooling liquid in the cleaning space. In addition, the surrounding part 3 can be made of transparent high-strength plastic material, so that the polishing and cleaning of the gasket in the cleaning space can be clearly observed, and timely adjustment can be made according to the polishing condition. The liquid spray head 4 is arranged on the gasket polishing workbench and is arranged on the inner side wall of the surrounding part 3 in the present embodiment. The liquid spray head 4 can spray cooling liquid on the gasket to cool it, and the cooling liquid can also flush away the polishing dust to ensure the polishing quality of the gasket. The liquid discharge groove 5 is arranged on the support surface of the support table 1 and is located in the cleaning space surrounded by the surrounding part 3. The liquid discharge groove 5 is used for discharging the cooling liquid and polishing dust converged on the support table 1. In the present embodiment, the liquid discharge groove 5 is arranged opposite to the liquid spray head 4. The inertia of the cooling liquid sprayed out of the liquid spray head 4 is more conducive to the discharge of the cooling liquid.

[0034] Preferably, the gasket polishing workbench further comprises a liquid collecting tank 6. The liquid collecting tank 6 is arranged on the support table 1, and the liquid inlet of the liquid collecting tank 6 is communicated with the liquid discharge groove 5.

[0036] Preferably, in order to further ensure the stability of the gasket during polishing, the gasket polishing workbench further comprises a plurality of magnetic members 8, the magnetic members 8 can be adsorbed to the support table 1 and / or the vacuum adsorption part 2, and the gasket can be clamped between the support surface of the support table 1 and the plurality of magnetic members 8. Although the method of vacuum adsorption can fix the gasket and make the gasket bear force uniformly, the gasket is easy to be detached when the vacuum degree is low or when coolant, dust and other pollutants enter. Generally, the gasket is detached after the polishing device is still polishing, causing poor surface quality of the gasket, machining precision out of tolerance or even grinding through, which seriously reduces the qualified rate of gasket assembly machining. The combination of vacuum adsorption and magnetic adsorption can effectively avoid the detachment of the gasket during polishing. The magnetic member is made of high-strength permanent magnetic material and has strong magnetic force, which can firmly fix the gasket.

[0038] Preferably, a plurality of liquid nozzles 4 and a plurality of gas nozzles 9 are arranged, and the plurality of gas nozzles 9 and the plurality of liquid nozzles 4 are arranged alternately. Such design can make the coolant and the gas uniformly cover the surface of the gasket, improving the cleaning and drying effect.

[0039] Preferably, the bottom of the support table 1 is provided with a plurality of universal wheels 11, which facilitates the movement of the gasket polishing workbench in the workshop and adjusts the working position. The universal wheels are made of rubber material, which has good wear resistance and silent effect, avoiding generating large noise during movement. At the same time, the bottom of the support table 1 is also provided with telescopic legs 12, which can be extended after the workbench reaches the specified position, supporting on the ground to increase the stability of the workbench, preventing the polishing precision from being affected by vibration during polishing. The bottom of the telescopic leg is covered with a non-slip pad, which further improves the friction with the ground and ensures the stability of the workbench.

[0040] Preferably, the support surface of the support table 1 is arranged at an angle with the horizontal plane, the liquid nozzle 4 is located at the side of the support surface with higher height, and the liquid discharge groove 5 is located at the side of the support surface with lower height. This inclined design is mainly to solve the problem that when the grinding disc diameter is large, the grinding dust is easily blocked in the grinding disc and cannot be discharged when the grinding disc is completely attached to the workpiece during polishing. By inclining the workbench base at a certain angle, not only can the angle calibration of the machine tool and robot be avoided every time the polishing device is replaced, but also the problem of angle adjustment of some machine tools and polishing devices can be solved. In addition, the inclination of the support surface to the end of the liquid discharge groove 5 can also make the cooling liquid flow out of the liquid nozzle 4 and naturally flow along the surface of the gasket to the liquid discharge groove 5, thereby effectively flushing away the grinding dust on the surface of the gasket and avoiding the accumulation of liquid on the support table 1. In this embodiment, the angle between the support surface of the support table 1 and the horizontal plane is set to 5°, but it is not limited to 5°, and the angle between the support surface and the horizontal plane can be set according to the actual situation. Other angles are also within the protection scope of this embodiment.

[0041] The gasket polishing workbench provided by the utility model solves the problem of grinding dust blockage by inclining the support surface of the support table 1 at a certain angle with the horizontal plane, improves the polishing quality; at the same time, the gasket is fixed by combining vacuum adsorption and magnetic attraction, avoiding the gasket detachment phenomenon, ensuring the stability of the gasket during polishing, thereby improving the processing precision and surface quality of the gasket and reducing the scrap rate; the liquid nozzle 4 and the gas nozzle 9 are staggered, which can select different cleaning methods according to the size of the grinding dust, effectively flushing away the grinding dust and reducing the problem of gasket thermal deformation; after polishing, the gas nozzle 9 can blow dry the residual grinding dust and cooling liquid on the surface of the gasket, ensuring the cleanliness of the gasket surface; the universal wheels 11 and telescopic legs 12 provided at the bottom of the support table 1 are convenient for moving and fixing; the design of the filter assembly 61 of the liquid collecting tank 6 is convenient for cleaning grinding dust and maintaining the equipment, and also realizes the recycling of the cooling liquid, saving resources and reducing production cost.
