Abstract
Description
Technical Field
[0001] This utility model relates to the field of polishing technology, specifically to a wire drawing and polishing mechanism. Background Technology
[0002] Machining refers to the process of altering the shape, size, or properties of a workpiece using mechanical equipment to ultimately obtain the desired product. Grinding and polishing are important machining methods. Polishing refers to the process of reducing the surface roughness of a workpiece using mechanical, chemical, or electrochemical methods to obtain a bright and smooth surface. It involves using polishing tools, abrasive particles, or other polishing media to refine the surface of a workpiece. In recent years, with technological advancements, the cost of various products such as mobile phones, smartwatches, tablets, and VR glasses has decreased, leading to their widespread adoption. When purchasing products, users pay more attention to appearance in addition to the product's functionality. Taking watches as an example, in the watchmaking process, to ensure aesthetic appeal, the surface needs to be treated, such as creating brushed textures and polishing. In traditional production, surface treatment is done manually, with brushing and polishing controlled by workers. This is inefficient and prone to inconsistent results due to varying worker skill levels. While some automated polishing equipment has emerged, the polishing process requires applying pressure to the product surface. Existing equipment is prone to excessive pressure, affecting the polishing effect and even causing excessive wear and damage to the product surface. Utility Model Content

[0021] To facilitate understanding of this utility model by those skilled in the art, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.
[0022] Example 1
[0023] Reference Figures 1 to 3 This utility model provides a wire drawing and polishing mechanism, including a base 1, a floating guide rail assembly 2 disposed on the base 1, a base plate 3 connected to the floating guide rail assembly 2, a wire drawing and polishing assembly 4 disposed on the base plate 3, and a pressure monitoring assembly 5. The base plate 3 can move along the floating guide rail assembly 2. During the wire drawing and polishing process, when the wire drawing and polishing assembly 4 contacts the workpiece, there is a contact force between the wire drawing and polishing assembly 4 and the workpiece. The base plate 3 will move in the opposite direction along the floating guide rail assembly 2. At this time, the pressure monitoring assembly 5 can monitor the magnitude of the force and feed it back to the control system in real time. The control system judges and analyzes the actual contact force according to the preset force value range, and automatically adjusts or issues a prompt for the operator to adjust. For example, when the detected force value is greater than the preset range, the control system issues an alarm message, indicating that the current product pressure is too high.
[0024] The pressure monitoring component 5 includes a fixed bracket 51 mounted on the base 1, a pressure sensor 52 mounted on the fixed bracket 51, and a pressure sensing element 53 connected to the base plate 3 and matching the pressure sensor 52. The sensing end of the pressure sensor 52 faces outward from the base 1, and the position of the pressure sensing element 53 corresponds to the sensing end of the pressure sensor 52. That is, the fixed bracket 51 is positioned near the center of the base 1, while the pressure sensing element 53 is located near the center of the base 1. Figure 1 Taking the perspective of the workpiece as an example, when the workpiece is located on the right front side, the contact force between the polishing and brushing assembly and the workpiece will drive the substrate 3 to move in the opposite direction, that is, the pressure sensing element 53 moves toward the pressure sensor 52, so that the contact force can be measured.
[0025] The wire drawing and polishing mechanism includes a limiting component 6, which comprises a limiting plate 61 disposed on the base 1, a limiting seat 62 disposed on the substrate 3, and a limiting adjustment member 63 disposed on the limiting seat 62. The substrate 3 is provided with a limiting hole 31, the upper end of the limiting plate 61 passes through the limiting hole 31, the limiting plate 61 is located near the middle of the substrate 3, and the limiting seat 62 is located near the edge of the substrate 3. The limiting component 6 can limit the movement distance of the substrate 3, thereby preventing the wire drawing and polishing component 4 from deviating significantly from the set position.

[0027] A support connector 45 is provided on the substrate 3, and the transmission shaft 43 passes through the support connector 45.
[0028] The floating guide rail assembly 2 includes two fixed seats 21 disposed on the base 1, a guide rod 22 connected between the two fixed seats 21, and a sliding seat 23 connected to the guide rod 22. The base plate 3 is connected to the sliding seat 23. The floating guide rail is driven by gas, and the sliding seat 23 has a gas inlet.

[0030] Both sides of the upper end of the pressure sensor 53 are designed with connecting portions 55. The connecting portions 55 are provided with waist-shaped holes 56. Fasteners pass through the waist-shaped holes 56 to fix the pressure sensor 53 at the recessed portion 32.
[0031] In practical implementation, this utility model is fixed on a processing machine table and works in conjunction with a robotic arm to perform wire drawing and polishing operations. The robotic arm has a mechanism for gripping or fixing the workpiece. During processing, the robotic arm drives the workpiece close to the processing wheel 44 of the polishing assembly, bringing the workpiece into contact with the processing wheel 44 for wire drawing or polishing. Simultaneously, the robotic arm can control the movement or rotation of the workpiece, thereby processing multiple areas of the workpiece. During the processing, the pressure monitoring component 5 monitors the contact force between the processing wheel 44 and the surface of the workpiece in real time and transmits the detected force signal to the control system. The control system judges and analyzes the actual contact force according to the preset force value range and makes timely adjustments.
