Description

Technical Field

[0001] This utility model relates to the field of polishing equipment technology, and in particular to a polishing equipment for hand-made models. Background Technology

[0002] The creation of prototype models plays a crucial role in the product prototyping and design stages. It can visually demonstrate the appearance and structure of the product, helping designers and clients to better understand the design scheme. However, after the prototype model is made, its surface often has defects such as scratches and burrs, which affect its aesthetics and texture, and therefore requires polishing.

[0003] With the continuous development of industrial automation technology, various polishing equipment has emerged, providing convenience for the polishing of prototype models. These devices not only improve processing efficiency but also ensure the consistency of polishing quality. However, for small prototype models, most equipment is not very adaptable, so small prototype models mainly rely on manual polishing. However, this method is inefficient and it is difficult to guarantee the consistency of precision and surface quality. At the same time, it is labor-intensive and can easily cause physical injury to the producers.

[0004] Therefore, we propose a hand-made model polishing device. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of existing technologies and to achieve efficient and precise polishing of small prototype models, thereby reducing the workload of producers.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A hand-made model polishing device includes a polishing table, which is installed on a polishing production line. A side plate is provided between the polishing table and the water tank of the polishing production line. A water tank groove is opened below the side plate. A crank-slider-connecting rod mechanism is installed on one side of the polishing table.

[0008] The crank-slider-connecting rod mechanism includes a crank, a connecting rod, and a polishing bracket. The connecting rod connects the crank and the polishing bracket. The back of the polishing bracket is slidably connected to a side plate. A polishing frame is installed at the other end of the polishing bracket. Polishing sandpaper is installed around the periphery of the polishing frame.

[0009] Furthermore, the water tank is connected to the water tank on the polishing production line.

[0010] Furthermore, the crank-slider linkage mechanism also includes a servo motor, with the crank mounted on the output end of the servo motor.

[0011] Furthermore, a dust cover is installed around the servo motor and crank, and a controller is installed on the dust cover and electrically connected to the servo motor.

[0012] Furthermore, the two ends of the connecting rod are connected to the crank and the polishing bracket through a rotary joint, converting the rotational motion of the crank into the linear motion of the polishing bracket.

[0013] Furthermore, the back of the polishing bracket is provided with a slider, which moves reciprocatingly in a linear motion along a guide groove opened on the side plate.

[0014] Furthermore, the polishing bracket is provided with an installation groove for inserting and installing the polishing frame. The end of the installation groove away from the connecting rod is provided with a side threaded hole, and a positive threaded hole is provided on the same side as the installation groove away from the side threaded hole. A secondary groove is provided in the installation groove corresponding to the positive threaded hole.

[0015] Furthermore, one side of the polishing frame is provided with a mounting block for docking with a secondary groove. The mounting block is fixed to the polishing frame and the mounting block by bolts connecting the side threaded hole and the positive threaded hole, thereby installing the polishing frame.

[0016] Furthermore, the polishing sandpaper is fitted and adhered to the outer periphery of the polishing frame.

[0017] Compared with the prior art, the beneficial effects of this utility model are:

[0018] 1. Designed for small prototype models, the producer only needs to hold the prototype model in hand and press it against the polishing sandpaper to carry out the work. The small prototype model can be held with both hands, making it easy to change the angle. This solves the problem that most polishing equipment has poor adaptability to small prototype models and can meet the polishing needs of small prototype models.

[0019] 2. By using a crank-slider-connecting rod mechanism, the rotational motion of the servo motor is converted into the linear motion of the polishing bracket, enabling the polishing bracket and polishing sandpaper to perform efficient and precise polishing of small prototype models, thereby improving polishing efficiency and quality consistency.

[0020] 3. The semi-automated polishing method has changed the situation where small prototype models mainly rely on manual polishing, reducing the labor intensity of producers and reducing the risk of physical injury caused by manual polishing. Attached Figure Description

[0035] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0036] Example 1

[0037] like Figure 1-4 As shown, this utility model provides a technical solution: a hand-made model polishing device, including a polishing table 1, which is installed on a polishing production line. The polishing production line is usually equipped with a water tank for water application and cleaning operations.

[0038] A side plate 2 is provided between the polishing table 1 and the water tank of the polishing production line. A water tank trough 3 is provided below the side plate 2. The design of the water tank trough 3 allows the debris and wastewater generated during the polishing process to flow into the water tank for easy cleaning. It also makes it easy to wet and clean the prototype model. A crank-slider-connecting rod mechanism 4 is installed on one side of the polishing table 1.

[0039] The crank-slider-connecting rod mechanism 4 includes a crank 41, a connecting rod 42, and a polishing bracket 43. The connecting rod 42 connects the crank 41 and the polishing bracket 43. This connection method can convert the rotational motion of the crank 41 into the linear motion of the polishing bracket 43. The back of the polishing bracket 43 is slidably connected to the side plate 2, which ensures the stability (movement guidance) of the polishing bracket 43 during the movement. A polishing frame 5 is installed at the other end of the polishing bracket 43. Polishing sandpaper 6 is installed around the polishing frame 5. The polishing operation is achieved by the contact friction between the polishing sandpaper 6 and the hand model.

[0040] Example 2

[0041] like Figure 1-4 As shown, based on Example 1, the water tank 3 is connected to the water tank (the water is polishing liquid plus water) on the polishing production line, which ensures that the wastewater and debris generated during the polishing process can flow smoothly into the water tank, keeping the working environment clean, and at the same time facilitating the cleaning of the prototype model with water.

[0042] The crank-slider linkage mechanism 4 also includes a servo motor 44. The crank 41 is mounted on the output end of the servo motor 44. The servo motor 44 can provide precise speed and position control, making the polishing operation more stable and efficient.

[0043] A dust cover 7 is installed around the servo motor 44 and the crank 41. The dust cover 7 does not obstruct the extension of the connecting rod 42. The dust cover 7 can prevent dust, debris and other objects from entering the servo motor 44 and the crank 41, thus extending the service life of the equipment. A controller is installed on the dust cover 7 and is electrically connected to the servo motor 44. The controller can be used to easily set parameters and control the operation of the servo motor 44.

[0044] The two ends of the connecting rod 42 are connected to the crank 41 and the polishing bracket 43 through a rotating joint. This rotating joint connection method ensures the flexibility and accuracy of the motion, and reliably converts the rotational motion of the crank 41 into the linear motion of the polishing bracket 43.

[0045] The back of the polishing bracket 43 is provided with a slider 45. The slider 45 moves back and forth in a straight line along the guide groove 21 opened on the side plate 2. The guide groove 21 guides the movement of the slider 45, further ensuring the straightness and stability of the movement of the polishing bracket 43.

[0046] The polishing bracket 43 has an installation groove 51 for inserting and installing the polishing frame 5. The end of the installation groove 51 away from the connecting rod 42 has a side threaded hole 52, and the same side of the installation groove 51 away from the side threaded hole 52 has a positive threaded hole 53. The installation groove 51 extends into the groove and is corresponding to the positive threaded hole 53. This design makes the installation and disassembly of the polishing frame 5 more convenient, and facilitates the installation of the polishing sandpaper 6 after disassembly.

[0047] With the above installation structure, a mounting block 55 with a mating groove 54 is provided on one side of the polishing frame 5. The side threaded hole 52 and the positive threaded hole 53 are bolted to fix the polishing frame 5 and the mounting block 55, thereby installing the polishing frame 5. This bolt connection method is simple and reliable, ensuring the firmness of the polishing frame 5 during the polishing process.

[0048] The polishing sandpaper 6 is attached to the outside of the polishing frame 5. The polishing sandpaper 6 is a key component for achieving the polishing function. It removes surface imperfections and roughness through friction with the prototype model.

[0049] It is worth mentioning that since the polishing of the prototype model is carried out on the polishing production line, the selection of polishing sandpaper 6 can be fixed, thus enabling assembly line operation.

[0050] The working process of this utility model is as follows: When using a prototype model polishing device, firstly, according to the shape of the prototype model and the polishing requirements, select a suitable polishing frame 5, then fix the polishing frame 5 with the polishing sandpaper 6 glued on it on the polishing bracket 43 to ensure that the installation is firm, and install it in the mounting groove 51 of the polishing bracket 43 with bolts.

[0051] Next, the operating parameters of the servo motor 44, such as speed and running time, are set by the controller. The servo motor 44 is then started, and the servo motor 44 drives the crank 41 to rotate. The crank 41 converts the rotational motion into the linear reciprocating motion of the polishing bracket 43 through the connecting rod 42. The polishing frame 5 on the polishing bracket 43 then performs linear reciprocating motion. The polishing sandpaper 6 contacts the surface of the prototype model and generates friction, thereby realizing the polishing operation of the prototype model.

[0052] Among them, the contact between the polishing sandpaper 6 and the surface of the prototype model is carried out by the producer holding the prototype model with both hands or one hand (size);

[0053] During the polishing process, the prototype model is wetted to improve the polishing effect and can be cleaned. The generated debris falls into the water tank 3 and flows into the water tank of the polishing production line. After polishing is completed, the servo motor 44 is turned off, the polished prototype model is removed, and the polishing sandpaper 6 is replaced or maintained as needed.

[0054] Through the above workflow, the prototype model polishing equipment of this utility model can achieve efficient and stable polishing operations, improving the quality and surface finish of the prototype model.

[0055] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
