Description

Technical Field

[0001] The utility model relates to the technical field of material processing, and more specifically, to a grinding device for processing elevator door panels. Background Art

[0002] Elevator door panels are an important part of the elevator door system, mainly involving the door panels of the elevator car door and floor door (also known as the elevator hall door). In the current door panel processing industry, although the level of automation and mechanization is constantly improving, many factories still rely on traditional manual polishing methods for the door panel polishing process. This method is not only inefficient, but also has many technical challenges and limitations. Specifically, when manually holding polishing tools to polish door panels, it is difficult to ensure the uniformity and consistency of polishing due to the limitations of human strength and precision. More importantly, due to the lack of effective limiting and fixing measures for the door panels during the polishing process, the door panels are very likely to shift or shake under the action of the polishing force, which not only increases the labor intensity of the operators, but also requires them to constantly adjust the position of the door panels to ensure accurate polishing. Existing limit devices often have deficiencies in design and application, and it is difficult to meet the needs of efficient and accurate polishing. Most of these devices use simple clamping methods, such as clamping the door panels with a clamp or fixed bracket of a robotic arm. However, this clamping method can only provide an initial fixing effect. During the long-term grinding process, the clamping effect will gradually weaken or even fail due to factors such as vibration, wear and elastic deformation of the material itself. This will not only cause the door panel to move frequently during the grinding process, affecting the grinding accuracy and surface quality, but may also pose a safety hazard to the operator, such as injury accidents caused by sudden detachment of the door panel. In addition, manual grinding also faces problems such as high labor intensity, poor working environment, and serious dust pollution. Operators are very likely to suffer from occupational diseases such as pneumoconiosis if they are in this working environment for a long time. At the same time, the efficiency and accuracy of manual grinding are difficult to compare with automated and intelligent equipment, which to a certain extent restricts the overall development level and economic benefits of the door panel processing industry.

[0021] When in use, first move the elevator door panel to be polished to the inside of the polishing groove 2, and then the staff starts the motor 4 through the external switch. The power generated by the motor 4 causes the gear 3 to rotate. Since the two groups of motors 4 are meshed on the side of the gear 3, the gear 3 drives the two groups of motors 4 to move relative to each other while rotating. Since the connecting strip 7 is fixedly installed between the round rod 6 and the rack 5, the two groups of racks 5 move relative to each other while driving the two groups of round rods 6 to move synchronously. Then, the two groups of round rods 6 gradually move to both sides of the elevator door panel, so that the two groups of limit plates 11 fix the two sides of the elevator door panel. At the same time, the cooperation between the telescopic rod 9 and the spring 10 makes the limiting effect of the limit plate 11 better, and then the elevator door panel is polished by the polishing disc 21;

[0022] The power of motor 14 causes the racks 5 on both sides of the gear 3 to move relative to each other, so that the two groups of limit plates 11 move synchronously, and the elevator door panel is limited by the two groups of limit plates 11. At the same time, the limit of the limit plate 11 is improved by the cooperation between the telescopic rod 9 and the spring 10. Compared with the traditional device, this device can ensure that the limit plate 11 remains stable during the movement through the cooperation between the gear 3 and the rack 5, avoiding damage to the door panel due to shaking or deviation, so that the position of the limit plate 11 can be accurately controlled to accurately limit the two sides of the door panel. At the same time, the cooperation between the telescopic rod 9 and the spring 10 can increase the limiting strength of the clamping plate, so that it fits more closely on both sides of the door panel, thereby improving the limiting effect, and can also withstand a certain lateral force to prevent the door panel from offsetting or shaking during the processing, and this device can adapt to the processing requirements of elevator door panels of different sizes and thicknesses.

The power of the motor three 20 makes the grinding disc 21 rotate continuously to polish the surface of the door panel. Then the staff starts the motor two 15 through the external switch. The power generated by the motor two 15 makes the threaded rod 26 rotate. The rotation of the threaded rod 26 makes the socket block 16 on its surface move on the surface of the threaded rod 26, and the grinding disc 21 moves synchronously with the movement of the socket block 16, and the surface of the door panel is polished by the movement of the grinding disc 21;

[0025] The force of the cylinder 18 pushes the square plate 19 downward so that the grinding disc 21 contacts the surface of the door panel, and then the motor three 20 is started. The power of the motor three 20 causes the grinding disc 21 to rotate to grind the surface of the door panel. Then the power of the motor two 15 causes the sleeve block 16 to move on the surface of the threaded rod 26, so that the grinding disc 21 moves synchronously, thereby grinding the surface of the door panel. Compared with the traditional device, this device can adapt to elevator door panels of different thicknesses, avoids the complexity of replacing grinding discs of different sizes or adjusting the entire device, improves processing efficiency, and thus reduces the cost and time consumption caused by frequent replacement of grinding discs. At the same time, it can achieve precise control of the position of the grinding disc 21, thereby helping to ensure the uniformity and consistency of grinding and improve the surface quality of the door panel. By precisely controlling the position and force of the grinding disc 21, it can reduce equipment wear and damage caused by excessive grinding or improper operation, thereby helping to maintain the equipment in good operating condition, extend its service life and reduce maintenance costs.

[0030] Among them, four groups of legs 29 are fixedly installed at the bottom of the workbench 1, and leg pads 30 are fixedly installed at the bottom of the four groups of legs 29;

[0031] Four groups of legs 29 are fixedly installed at the bottom of the workbench 1, and leg pads 30 are fixedly installed at the bottom of the four groups of legs 29.

[0033] The inner diameter value of the slide groove 22 is set to be equal to the outer diameter value of the slide plate 24, and the inner diameter value of the transverse groove 23 is set to be equal to the outer diameter value of the slider 25, so that the slider 24 fits better when sliding inside the slide groove 22, and the slider 25 also fits better when sliding inside the transverse groove 23, thereby improving the stability of the rectangular plate 17.

[0034] The working principle and use process of this utility model:

[0035] When in use, first move the elevator door panel to be polished to the inside of the polishing groove 2, and then the staff starts the motor 4 through the external switch. The power generated by the motor 4 causes the gear 3 to rotate. Since the two groups of motors 4 are meshed on the side of the gear 3, the gear 3 drives the two groups of motors 4 to move relative to each other while rotating. Since the connecting strip 7 is fixedly installed between the round rod 6 and the rack 5, the two groups of racks 5 move relative to each other and drive the two groups of round rods 6 to move synchronously. Then, the two groups of round rods 6 gradually move to both sides of the elevator door panel, so that the two groups of limit plates 11 fix the two sides of the elevator door panel. At the same time, the cooperation between the telescopic rod 9 and the spring 10 makes the limiting effect of the limit plate 11 better, and then the elevator door panel is polished by the polishing disc 21.

[0036] When in use, the staff starts the cylinder 18 through the external switch. The force of the cylinder 18 pushes the square plate 19 downward and makes the grinding disc 21 contact the surface of the elevator door panel to be polished. Then the motor three 20 is started. The power of the motor three 20 makes the grinding disc 21 rotate continuously to polish the surface of the door panel. Then the staff starts the motor two 15 through the external switch. The power generated by the motor two 15 makes the threaded rod 26 rotate. The rotation of the threaded rod 26 makes the socket block 16 on its surface move on the surface of the threaded rod 26. The grinding disc 21 moves synchronously with the movement of the socket block 16, and the surface of the door panel is polished by the movement of the grinding disc 21.
