Description

Technical Field

[0001] This utility model relates to the field of electrical appliance casing processing technology, and more specifically, to a polishing device for the production and processing of electrical appliance casings. Background Technology

[0002] Polishing of appliance casings involves using tools such as sandpaper, polishing wheels, and polishing paste, either mechanically or manually, to remove burrs, scratches, and oxide layers from the casing surface, resulting in a smooth and glossy finish. This process not only enhances the product's appearance but also improves the casing's corrosion resistance and wear resistance, and is widely used in home appliances, electronic devices, and other fields.

[0003] A search revealed CN212735519U, which discloses a surface polishing device for electrical appliance processing housings. The device includes a base plate and an electro-hydraulic telescopic rod. The base plate has a pulley groove with a pulley mounted on it. A support seat is mounted on the pulley and welded to the bottom end of the electro-hydraulic telescopic rod. A hanging rail is welded between the top ends of the electro-hydraulic telescopic rod. A polishing machine is suspended from the hanging cabinet. The polishing machine includes a fixing device and a polishing machine housing. A first drive shaft and a second drive shaft pass through the polishing machine. A spline device is installed between the first and second drive shafts, and the spline device includes a sleeve and a shaft spline.

[0004] However, this type of electrical appliance casing surface polishing equipment still has some drawbacks. For example, although the technical solution improves the automation level and processing accuracy of the polishing machine by introducing the movement of pulleys and hanging wheels, and enhances the working stability of the equipment by using universal joints and spline devices, the obstruction of the fixture and the fact that the polishing machine can only polish a single surface of the electrical appliance casing in a single operation result in the inability to complete the polishing treatment at the connection between the two sides of the casing in one go. This design defect not only reduces the processing efficiency, but may also lead to inconsistency in the overall polishing accuracy, affecting the quality of the final product. Utility Model Content

[0028] The polishing mechanism 8 has three sets, which are respectively located at the bottom end of the hydraulic cylinder 7 and the bottom ends of the two sets of side auxiliary polishing components 9.

[0029] By setting up the hanging rail moving mechanism 5, which is a cam mechanism in the prior art, a mechanical device that converts rotational motion into linear motion or oscillating motion according to a specific law, mainly composed of a cam, a follower and a frame, the hanging rail moving mechanism 5 can move linearly on the top of the support 4. Combined with the linear guide rail mechanism 3, it realizes the multi-position adjustment of the polishing mechanism 8 and achieves a comprehensive grinding and polishing effect.

[0030] By setting up a polishing mechanism 8, the motor drives the rotating shaft and the external polishing belt to rotate, so that the polishing belt fits into the appliance shell for polishing.

[0031] The equipment also includes a clamping mechanism 2, a linear guide mechanism 3, and a polishing paste application assembly 10. The clamping mechanism 2 is symmetrically arranged in two sets on the upper surface of the middle part of the processing table 1.

[0032] By setting a linear guide mechanism 3, which is a ball screw mechanism in the prior art, the rotational motion of the threaded rod can be converted into linear motion by a motor. It has the characteristics of high efficiency, high precision and reversibility. Thus, the linear guide mechanism 3 is used to drive the threaded bracket 4, side connecting plate 93 and other components to move linearly.

[0034] The polishing paste application assembly 10 includes a hydraulic cylinder 100, a storage tank 105, and a nozzle 108. A rotating mechanism 101 is fixedly installed on the outer surface of the middle part of the hydraulic cylinder 100. A top plate 102 is fixedly installed on the top of the hydraulic cylinder 100. A motor 103 is fixedly installed on the upper surface of the middle part of the top plate 102. A brush 104 is fixedly sleeved at the output end of the motor 103.

Several nozzles 108 are provided on the inner surface of the top plate 102, and the top ends of the several nozzles 108 are connected to the inner surface of the top end of the connecting pipe 107.

[0035] By setting up the polishing paste application component 10, when the operator applies polishing paste to the surface of the electrical appliance casing, the electrical appliance casing can be flipped over after the single-sided application is completed, and the three surfaces that need to be processed can be applied sequentially. Then, the clamping mechanism 2 is used to clamp and fix the casing and perform subsequent polishing.

[0036] The rotating mechanism 101 includes a second motor 1010 and a driven gear 1012. The outer surface of the second motor 1010 is fixedly installed on the inner surface of the processing table 1.

Grooves for the movement of the outer shell 90 are provided in the middle of both sides of the fixing plate 6.

[0038] The working process of this utility model is as follows:

[0039] When polishing the appliance casing, the operator uses clamping mechanism 2 to clamp the casing. Then, the hydraulic cylinder 7 extends, causing the polishing mechanism 8, fixedly mounted at its bottom, to move downwards and fit against the upper surface of the casing. Simultaneously, the motor 94 starts, and the gear 95, fixedly sleeved at its output end, rotates inside the movable block 92, pulling the rack 91 meshing with the gear 95 downwards. The casing 90 moves downwards along the surface of the middle of the movable block 92, moving the polishing mechanism 8 at the bottom of the casing 90 to a position parallel to the side of the casing. Then, the linear guide mechanism 3 in the control device adjusts the position of the movable block 92. The polishing mechanism 8 at the bottom of the outer casing 90 is brought into contact with the side edge of the electrical casing, or the adjusting bracket 4 is moved along the width direction of the processing table 1, so that the polishing mechanism 8 installed at the bottom of the hydraulic cylinder 7 moves on the upper surface of the electrical casing. Therefore, when polishing the electrical casing once, the operator uses the linear guide mechanism 3, the hanging rail moving mechanism 5, the side auxiliary polishing component 9 and other structures to adjust the positions of the three polishing mechanisms 8 arranged in a "U" shape on the top and sides of the electrical casing to complete the polishing and grinding process of the electrical casing, thereby improving the polishing and grinding efficiency to a certain extent and improving the consistency of the overall surface quality.

[0040] Before polishing the appliance casing, the operator can control the motor 2 1010 to drive the main gear 1011 connected to the output end to rotate, which in turn drives the meshing slave gear 1012 and the hydraulic cylinder 2 100 fixed in the middle to rotate, causing the top plate 102 to rotate to the top of the clamped appliance casing. At this time, the polishing paste inside the storage tank 105 is pumped into the connecting pipe 107 by the liquid pump 106, and then flows into the nozzle 108 along the connecting pipe 107 and is sprayed onto the top of the appliance casing. Then, the operator controls the motor 3 103 to drive the brush 104 connected to the output end to rotate, and adjusts the brush 104 to fit the upper surface of the appliance casing by the extension and retraction of the hydraulic cylinder 2 100, so that the polishing paste on the surface is evenly applied, thereby further assisting the polishing mechanism 8 in polishing the appliance casing and improving product quality.
