Description

Technical Field

[0001] The invention belongs to the technical field of drilling and milling machine tools, and in particular relates to a processing device for metal accessories for doors and windows. Background Art

[0002] Hardware accessories processing is the process of processing metal materials (such as steel, aluminum, copper, etc.) into parts with specific shapes, sizes and performances through cutting, forming, connecting and other processes. It is widely used in machinery manufacturing, electronics, automobiles, furniture and other fields. Its core goal is to achieve high-precision, high-efficiency, low-cost mass production, while meeting the diverse needs of different industries for accessories strength, corrosion resistance, surface accuracy, etc.

[0003] In the field of hardware accessories processing, milling is a common process for forming keyways, planes and other features. However, the problem of metal debris splashing during high-speed milling has long existed. Traditional splash-proof devices are mostly fixed structures, and their protection range and angle cannot be dynamically adjusted with the speed of the milling cutter, resulting in violent debris splashing during high-speed processing. Not only may it cause scratch risks to operators, but it will also contaminate machine tool guides and transmission components, increase equipment wear and cleaning costs. In addition, fixed splash-proof devices usually use fully enclosed or fixed baffles, which are difficult to accurately match the splash path in the direction of travel of the milling cutter. There are blind spots in protection, and the observation and debugging of the processing process may be affected by blocking the line of sight. In the prior art, some splash-proof devices achieve angle adjustment through additional electronic control or hydraulic systems, but such solutions increase the complexity and energy consumption of the device, and are prone to electronic component failures or hydraulic leakage problems in long-term industrial environments, and are insufficiently reliable.

[0004] At the same time, the workpiece clamping devices of traditional processing equipment are mostly one-way fixed structures. When processing multi-directional keyways, the workpiece needs to be frequently disassembled and repositioned, resulting in low processing efficiency and the positioning accuracy is greatly affected by human operation. Summary of the invention

[0005] In view of the existing technical problems that traditional splash-proof devices are mostly fixed structures, their protection range and angle cannot be dynamically adjusted with the milling cutter speed, resulting in violent splashing of debris during high-speed processing, which may not only cause scratches to operators, but also contaminate machine tool guides and transmission components, increase equipment wear and cleaning costs, and thus a hardware accessories processing integrated device is proposed.

[0006] Its purpose is: the centrifugal force-driven dynamic splash-proof unit uses the centrifugal force when the milling cutter rotates as the power source, without the need for an additional drive system, to achieve adaptive adjustment of the splash-proof plate angle with the rotation speed, and to accurately block the splash of debris under different working conditions; at the same time, by improving the rotating clamping device, rapid positioning and multi-angle processing of the workpiece can be achieved, effectively improving processing safety, precision and efficiency, and making up for the shortcomings of traditional fixed splash-proof devices and one-way clamping structures.

[0007] The technical solution of the present invention is a hardware accessories processing integrated device, which is used for processing a workpiece, including a milling machine, a processing seat arranged on the milling machine, a rotating clamping device arranged on the processing seat, a driving device arranged on the milling machine, the workpiece is arranged on the rotating clamping device, a keyway is opened on the workpiece, a mounting seat arranged at the bottom of the driving device, a milling cutter arranged at the bottom of the mounting seat, and also includes a splash-proof unit arranged near the milling cutter; The splash-proof unit includes a mounting groove in a circular array on the mounting seat, a spring arranged in the mounting groove, a weight block arranged on one side of the spring, a support plate arranged at the bottom of the driving device, and a splash-proof plate arranged on the support plate. The splash-proof plate includes a driving part arranged on the support plate and a splash-proof part arranged on one side of the driving part. The splash-proof plate is formed by integrally connecting the driving part and the splash-proof part, and a through hole is opened in the middle of the splash-proof part for the milling cutter to pass through.

[0008] Furthermore, rotating rods are provided on both sides of the driving part, and the rotating rods are rotatably connected to the supporting plate through torsion springs.

[0009] Furthermore, the driving portion is in the shape of a three-quarter arc, and a gentle surface is provided on one side of the top thereof.

[0010] Furthermore, the bottom of the splash-proof portion is in a concave spherical shape.

[0011] Furthermore, sliding surfaces are provided on both sides of the driving part.

[0012] Furthermore, a side of the splash-proof portion away from the support plate is longer than another side of the splash-proof portion.

[0013] Furthermore, a slope is provided on one side of the slow surface, and both the slow surface and the slope have a smoothly curved arc in the radial direction of the driving part.

[0014] Furthermore, a baffle is provided at a position on the top of the driving portion, which is located on one side of the inclined surface, and the baffle has a smoothly curved arc in the radial direction of the driving portion.

[0015] Furthermore, the rotating clamping device includes a base arranged on the processing seat, a handle arranged on the side of the base, a clamping seat arranged on the base, a plurality of clamping blocks arranged in a circular array on the clamping seat, and the workpiece is clamped in the middle of the plurality of clamping blocks.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The splash-proof unit has a dynamic adaptive splash-proof function, which can accurately match the processing requirements. The splash-proof plate angle is automatically adjusted with the milling cutter speed. The faster the speed, the greater the displacement of the weight tension spring driven by centrifugal force, and the closer the splash-proof part is to the milling part, forming a dynamic match of "speed-splash-proof effect", which specifically blocks the more violently splashed debris during high-speed milling, avoiding the blind spot of the traditional fixed splash-proof device, and drives the splash-proof plate to rotate obliquely downward by centrifugal force, accurately blocking the debris splash path in the direction of the milling cutter, especially for the radial splash problem caused by the high-speed rotation of the tool during milling, the protection is more accurate and efficient; 2. The concave spherical shape can intercept the flying debris to the greatest extent and improve the interception effect of the debris. It can not only intercept the debris in the direction of the milling cutter, but also intercept the debris flying on both sides of the milling cutter, so as to avoid the pollution of the air in the processing plant caused by the flying debris, reduce the cleaning frequency of the equipment and working area after processing, improve the production efficiency and improve the workshop environment; 3. This device has no additional power drive and has a simple and reliable structure. It uses the centrifugal force of the milling cutter as the power source of the splashproof unit. It does not require additional electronic control or hydraulic systems, reduces the complexity and energy consumption of the device, improves stability and reliability, and reduces failure points.

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0026] Example 1, reference Figure 1-Figure 7 , which is the first embodiment of the present invention, provides a hardware accessories processing integrated device for processing a workpiece 4, including a milling machine 1, a processing seat 2 installed on the milling machine 1, a rotating clamping device 9 installed on the processing seat 2, a driving device 3 installed on the milling machine 1, the workpiece 4 is clamped on the rotating clamping device 9, a keyway 5 opened on the workpiece 4, a mounting seat 6 installed at the bottom of the driving device 3, a milling cutter 7 clamped and fixed at the bottom of the mounting seat 6, and also includes a splash-proof unit 8 installed near the milling cutter 7; the splash-proof unit 8 includes an annular array A mounting groove is provided on the mounting seat 6, a spring 81 fixedly connected in the mounting groove, a weight block 82 fixedly connected to one side of the spring 81, a support plate 83 fixedly connected to the bottom of the driving device 3, and a splash plate 84 rotatably connected to the support plate 83. The splash plate 84 includes a driving portion 841 rotatably connected to the support plate 83, and a splash plate 842 fixedly connected to one side of the driving portion 841. The splash plate 84 is formed by integrally connecting the driving portion 841 and the splash plate 842. A through hole 85 is provided in the middle of the splash plate 842 for the milling cutter 7 to pass through.

[0027] Specifically, when processing hardware accessories, the workpiece 4 is clamped on the rotating clamping device 9 and fixed, and the driving device 3 is started to rotate the milling cutter 7 at the bottom. At the same time, the rotating clamping device 9 is driven forward by the cylinder, so that the workpiece 4 is opened with a keyway 5 by the milling cutter 7. When the driving device 3 drives the milling cutter 7 to rotate, the mounting seat 6 is also driven to rotate synchronously. At this time, under the action of centrifugal force, the weight block 82 located in the mounting groove stretches the spring 81 and moves to the side away from the spring 81, so that one end of the weight block 82 squeezes the splash guard. The driving part 841 on the plate 84 drives the splash guard 842 to rotate obliquely downward in the direction of the milling cutter 7, so as to block the debris splashed from the direction of travel of the milling cutter 7 when the milling cutter 7 rotates. When the milling cutter 7 rotates faster, the centrifugal force on the weight block 82 is greater, and the weight block 82 will slide out of the mounting groove further, and the extrusion displacement of the driving part 841 will be greater, so that the driving part 841 drives the splash guard 842 to rotate at a greater angle, that is, the splash guard 842 is closer to the milling part of the milling cutter 7. Since the faster the milling speed of the milling cutter 7 is, the faster the speed of the debris generated and the intensity of the splashing are, the closer the splash guard 842 is to the milling part of the milling cutter 7, the further the debris splashing can be avoided. It has a dynamic adaptive splash-proof function, which can accurately match the processing requirements. The angle of the splash guard 84 is automatically adjusted with the rotation speed of the milling cutter 7. The faster the rotation speed, the greater the displacement of the weight 82 stretching the spring 81 driven by the centrifugal force, and the closer the splash guard 842 is to the milling part, forming a dynamic match of "rotation speed-splash guard effect", which can specifically block the more violent splashing of debris during high-speed milling, avoid the blind spot of traditional fixed splash guard devices, and drive the splash guard 84 to rotate obliquely downward by centrifugal force, accurately blocking the debris splashing path in the direction of travel of the milling cutter 7, especially for the radial splash problem caused by the high-speed rotation of the tool during milling, so that the protection is more accurate and efficient.

[0028] Reference Figure 4-Figure 5 The driving portion 841 is fixedly connected to two sides with a rotating rod 86 , and the rotating rod 86 is rotatably connected to the supporting plate 83 through a torsion spring (not shown in the figure).

[0029] Specifically, under the force of the torsion spring, when the milling cutter 7 does not rotate, the rotating rod 86 will drive the splash plate 84 to return and rotate, and fit against the bottom of the mounting seat 6. This design makes it easy to check and replace the milling cutter 7.

[0030] Reference Figure 5 The driving portion 841 is in the shape of a three-quarter arc, and a gentle surface 87 is provided on one side of its top, and the gentle surface 87 is in an arc shape.

[0031] Specifically, the drive part 841 and the splash-proof part 842 are integrally formed, which has a simple structure and rich effects. The arc-shaped design of the drive part 841 not only saves space and materials, but also can realize the splash-proof function of the drive splash-proof part 842. The structure is simple and efficient. When the milling cutter 7 rotates, the weight block 82 slides out under the action of centrifugal force and squeezes the slow surface 87, so that the drive part 841 drives the splash-proof part 842 to rotate downward, thereby realizing the splash-proof effect.

[0032] Reference Figure 6-Figure 7 The bottom of the splash guard 842 is in a concave spherical shape.

[0033] Specifically, the concave spherical shape can intercept the flying debris to the greatest extent, improve the interception effect of the debris, and can not only intercept the debris in the direction of the milling cutter 7, but also intercept the debris flying on both sides of the direction of the milling cutter 7, so as to avoid the pollution of the air in the processing plant caused by the flying debris, reduce the cleaning frequency of the equipment and working area after processing, improve production efficiency, and improve the workshop environment. In addition, the device has no additional power drive, and the structure is simple and reliable. The centrifugal force when the milling cutter 7 rotates is used as the power source of the splash-proof unit 8. No additional electric control or hydraulic system is required, which reduces the complexity and energy consumption of the device, improves stability and reliability, and reduces the failure points. The integrated design integrates the splash-proof unit 8 with the drive device 3 and the mounting seat 6, and the weight block 82, spring 81, splash-proof plate 84 and other components are compactly arranged, do not occupy additional space, adapt to the existing milling machine 1 structure, and are easy to install and maintain. The through hole 85 of the splash guard 842 allows the milling cutter 7 to move freely, and at the same time forms a dynamic protective barrier through angle adjustment, effectively reducing the risk of injury to operators caused by splashing metal debris during processing, as well as the wear and pollution of machine tool guide rails and transmission components caused by scattered debris.

[0034] Reference Figure 6 , sliding surfaces 88 are provided on both sides of the driving portion 841.

[0035] Specifically, the design of the sliding surface 88 facilitates the weight block 82 to quickly enter the gentle surface 87 when rotating.

[0036] Reference Figure 3 and Figure 5 , one side of the splash-proof portion 842 away from the support plate 83 is longer than the other side of the splash-proof portion 842 .

[0037] Specifically, the splash guard 842 is convenient for intercepting debris when rotating, thereby increasing its interception range.

[0038] Example 2, reference Figure 5-Figure 6 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that a slope 89 is provided on one side of the gentle surface 87, and both the gentle surface 87 and the slope 89 have a smoothly curved arc in the radial direction of the driving portion 841.

[0039] Specifically, the design of the inclined surface 89, relative to the gentle surface 87, can realize the rapid rotation of the driving part 841. When the rotation speed of the milling cutter 7 reaches the threshold, one end of the weight block 82 will enter the inclined surface 89 from the gentle surface 87, so that the driving part 841 can rotate to the specified angle at the fastest speed to block the violently splashing debris. The gentle surface 87 and the inclined surface 89 have a curved and smooth arc in the radial direction of the driving part 841. In order to facilitate the compression of the weight block 82 during the rotation process, the impact area of ​​the weight block 82 on the driving part 841 when the weight block 82 rotates is minimized. For high-speed milling scenarios (such as high-precision keyway 5 processing), the splash-proof effect automatically increases with the rotation speed, avoiding scratches or dimensional deviations on the processing surface caused by debris splashing, and indirectly improving the processing accuracy and quality stability. And without manual intervention, it can automatically adapt to different processing speeds (such as switching between rough milling and fine milling), meet the protection needs under multiple working conditions, and improve the versatility of the device.

[0040] Reference Figure 6 A baffle 90 is fixedly connected to the top of the driving portion 841 at a position on one side of the inclined surface 89 , and the baffle 90 also has a smoothly curved arc in the radial direction of the driving portion 841 .

[0041] Specifically, when the rotation speed of the milling cutter 7 reaches a certain value, the weight block 82 will be blocked by the baffle 90. If the rotation speed continues to increase, the driving part 841 will no longer drive the splash guard 842 to rotate, so as to prevent the splash guard 842 from rotating too much and affecting the milling of the milling cutter 7. The driving part 841 is also protected to prevent the weight block 82 from hitting the support plate 83 and causing damage to the support plate 83 and the weight block 82. The rest of the structure is the same as that of the first embodiment.

[0042] Example 3, reference Figure 1-Figure 2 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the rotating clamping device 9 includes a base 91 fixedly connected to the processing seat 2, a handle rotatably connected to the side of the base 91, a clamping seat 92 installed on the base 91, and a plurality of clamping blocks 93 slidably connected to the clamping seat 92 in an annular array, and the workpiece 4 is clamped in the middle of the plurality of clamping blocks 93.

[0043] Specifically, the rotating clamping device 9 is used to clamp and rotate the workpiece 4. When the workpiece 4 has milled a keyway 5, the handle is rotated so that the clamping seat 92 drives the clamping block 93 to rotate, thereby driving the workpiece 4 to rotate, so as to mill the next keyway 5. The remaining structure is the same as that of Example 2.

[0044] In summary, the working principle of the present invention is as follows: when processing hardware accessories, the workpiece 4 is clamped on the rotating clamping device 9 and fixed, the driving device 3 is started to rotate the milling cutter 7 at the bottom, and the rotating clamping device 9 is driven forward by the cylinder, so that the workpiece 4 is opened with a keyway 5 by the milling cutter 7. When the driving device 3 drives the milling cutter 7 to rotate, the mounting seat 6 is also driven to rotate synchronously. At this time, under the action of centrifugal force, the weight block 82 located in the mounting groove stretches the spring 81 and moves to the side away from the spring 81, so that the weight block 8 2 one end squeezes the driving part 841 on the splash plate 84, so that the driving part 841 drives the splash plate 842 to rotate obliquely downward in the direction of the milling cutter 7, thereby blocking the debris splashed from the direction of travel of the milling cutter 7 when the milling cutter 7 rotates, and when the milling cutter 7 rotates faster, the centrifugal force on the weight block 82 is greater, and it will slide out of the installation slot further, and the squeezing displacement of the driving part 841 is greater, so that the driving part 841 drives the splash plate 842 to rotate at a greater angle, that is, the splash plate 842 is closer to the milling part of the milling cutter 7. Since the faster the milling speed of the milling cutter 7, the greater the speed of generating debris and the intensity of splashing, at this time, the closer the splash plate 842 is to the milling part of the milling cutter 7, the further the debris splashing can be avoided. It has a dynamic adaptive splash-proof function, which can accurately match the processing requirements. The angle of the splash guard 84 is automatically adjusted with the rotation speed of the milling cutter 7. The faster the rotation speed, the greater the displacement of the weight 82 stretching the spring 81 driven by the centrifugal force, and the closer the splash guard 842 is to the milling part, forming a dynamic match of "rotation speed-splash guard effect", which can specifically block the more violent splashing of debris during high-speed milling, avoid the blind spot of traditional fixed splash guard devices, and drive the splash guard 84 to rotate obliquely downward by centrifugal force, accurately blocking the debris splashing path in the direction of travel of the milling cutter 7, especially for the radial splash problem caused by the high-speed rotation of the tool during milling, so that the protection is more accurate and efficient.

[0045] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
