Description

Technical Field

[0001] This utility model relates to a polishing machine, and more particularly to a novel eccentric polishing machine. Background Technology

[0002] An eccentric polishing machine is an industrial device that utilizes eccentric motion to improve surface treatment quality. Its core principle is to drive a polishing disc through a composite rotation (rotation combined with revolution) via an eccentric shaft, creating an irregular motion trajectory that avoids repetitive grinding paths, thereby uniformly removing surface defects. It is suitable for metals (such as automotive parts and molds), stone (tiles and countertops), glass, ceramics, and wood-plastic products, covering manufacturing, construction, and crafts industries. In existing eccentric polishing machines, the eccentric block is encapsulated inside the machine, and the eccentricity (amplitude) and rotation speed (such as the eccentric shaft speed) are pre-fixed by the mechanical structure, making dynamic adjustment impossible based on workpiece material, surface condition, or process requirements. Adjusting eccentric parameters requires stopping the machine, disassembling the casing, and manually replacing the eccentric block or adjusting the shaft system, which is cumbersome, poses safety hazards, and significantly reduces production efficiency. If multiple eccentric paths are required, multiple polishing machines with different parameters need to be purchased, increasing costs. Utility Model Content

[0003] A novel eccentric polishing machine features a main unit connected to an eccentric head. The eccentric head is detachable and replaceable, comprising an eccentric connector and an eccentric sleeve. The eccentric connector includes an eccentric block and is connected to the polishing head. Different sizes of eccentric blocks can be replaced with eccentric connectors for different applications. This invention solves the problem of non-adjustable eccentricity and rotation speed in existing eccentric polishing machines by providing a conveniently disassembled and replaceable eccentric head with an eccentric connector incorporating an eccentric block, allowing for the selection of different eccentricities and rotation speeds according to various applications.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A novel eccentric polishing machine has a main unit connected to an eccentric head. The eccentric head includes an eccentric connector and an eccentric sleeve. The eccentric connector is equipped with an eccentric block and is connected to the polishing head. The eccentric connector with different sized eccentric blocks can be replaced according to different uses.

[0006] Further, the power connection threaded hole of the eccentric connector is connected to the power output threaded shaft of the main unit to transmit the rotational kinetic energy of the main unit.

[0007] Furthermore, the polishing head locking hole of the eccentric head is connected to the connecting shaft of the polishing head, so as to transmit the power transmitted through the eccentric connector to the polishing head to realize the eccentric movement of the polishing head.

[0008] Further, the inner wall of the eccentric protective sleeve is provided with a fixing pin, which engages with the eccentric protective sleeve mounting position on the outer wall of the main unit, realizing a detachable connection between the eccentric protective sleeve and the main unit. The eccentric protective sleeve is used to prevent the user from coming into contact with the eccentric connecting parts and causing injury.

[0009] This invention solves the problem of the non-adjustable eccentricity and rotation speed of existing eccentric polishing machines by using an eccentric head that is easy to disassemble and replace, and an eccentric connector with an eccentric block built into the eccentric head.

[0017] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0019] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views of the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0021] like Figures 1-4 As shown: This utility model provides a new type of eccentric polishing machine. The main unit 1 is connected to the eccentric head 2. The eccentric head 2 includes an eccentric connector 3 and an eccentric protective sleeve 4. The eccentric connector 3 is provided with an eccentric block 32. The eccentric connector 3 is connected to the polishing head 5. The eccentric connector 3 with different sizes of eccentric blocks 32 can be replaced according to different uses.

[0022] The main unit 1 is equipped with a power output device, whose output end transmits rotational kinetic energy outward through a threaded power output shaft 11. To achieve stable power transmission, the eccentric connector 3 is provided with a matching power connection threaded hole 31. During assembly, the power connection threaded hole 31 on the eccentric connector 3 is screwed into the power output threaded shaft 11 of the main unit 1, thereby ensuring that the rotational energy output by the main unit can be reliably transmitted to the eccentric connector 3.

[0023] The eccentric head 2 consists of an eccentric connector 3 and an eccentric sleeve 4, and is detachable and replaceable. The eccentric connector 3 contains an eccentric block 32. When the workpiece or surface condition changes, the operator only needs to disassemble the eccentric head 2 and replace it with an eccentric connector 3 containing eccentric blocks 32 of different sizes to achieve different eccentric motion modes without requiring extensive modifications to the main unit or other transmission components.

[0024] The eccentric connector 3 is also connected to the polishing head 5 through a specially designed connection method. The eccentric head 2 is provided with a polishing head locking hole 33, while the polishing head 5 is provided with a connecting shaft 51. During assembly, the connecting shaft 51 of the polishing head 5 is inserted into the locking hole 33 in the eccentric head 2 and locked in place by a corresponding fixing device, so that the rotational kinetic energy transmitted through the eccentric connector 3 can be stably transmitted to the polishing head 5, thereby enabling the polishing head 5 to make a predetermined eccentric motion trajectory according to the design requirements.

[0025] To prevent potential safety hazards caused by direct contact with the eccentric connector 3 during use, an eccentric protective sleeve 4 is provided on the outside of the eccentric head 2. A fixing pin 41 is provided on the inner wall of the eccentric protective sleeve 4, which engages with the eccentric protective sleeve mounting position 12 on the outer wall of the main unit 1. This ensures a secure connection between the eccentric protective sleeve 4 and the main unit 1 while facilitating quick disassembly and installation. The eccentric protective sleeve 4 not only provides protection but also isolates the operator from direct contact with internal transmission components during equipment operation, reducing operational risks.

[0026] This invention enables flexible adjustment of the eccentricity and rotation speed of the eccentric polishing machine by replacing the eccentric connector 3 with different eccentric blocks 32. This technical solution has significant advantages in dealing with different materials, surface conditions, and processing requirements.

[0027] The adjustment and usage steps of this utility model are as follows:

[0028] 1. Fix the main unit 1 on the workbench and ensure that the main unit output shaft 11 is not loose and runs smoothly.

[0029] 2. Remove the existing eccentric head 2 and connect the new eccentric head 2 to the eccentric connector 3 and the power output threaded shaft 11 of the main unit 1 through a threaded connection.

[0030] 3. Insert the eccentric protective sleeve 4 into the main unit 1, so that the internal fixing pin 41 is engaged with the eccentric protective sleeve mounting position 12 on the outer wall of the main unit 1, to ensure safe operation after installation.

[0031] 4. Insert the connecting shaft 51 of the polishing head 5 into the polishing head retaining hole 33 on the eccentric head 2, and confirm that the connection is secure.

[0032] 5. Start the main unit 1 and observe the linkage of each component. If the eccentric motion does not meet the requirements, it can be adjusted by replacing the eccentric block 32 in the eccentric connector 3 until the expected effect is achieved.

[0033] The novel eccentric polishing machine disclosed in this embodiment employs a detachable and replaceable eccentric head design, allowing for rapid switching of eccentricity and rotation speed according to different processing requirements. Compared with existing technologies, this invention is not only simpler to operate and more flexible in adjustment, but also significantly improves equipment safety and production efficiency.

[0034] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no conflict in the mechanism, the features in the embodiments disclosed in the present invention can be combined with each other in any way. The lack of an exhaustive description of these combinations in this specification is merely for the sake of brevity and resource conservation. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
