Description

Technical Field

[0001] The present invention relates to the technical field of metal processing equipment, and more particularly, to a spinning machine. Background Art

[0002] A spinning machine is a key mechanical device for metal plastic forming. It fixes a blank on a clamping device, rotates it by means of a blank supporting device, and then applies pressure to the outside of the blank by a spinning wheel for shaping. This process causes plastic deformation of the metal blank and finally manufactures precise metal parts. Due to the unique advantages of the spinning machine in producing thin-walled and high-precision parts, it has been widely used in the metal processing industry. According to the number of spinning wheels, spinning machines can be divided into different types such as single-wheel, double-wheel, and three-wheel. Among them, the three-wheel spinning machine can meet the processing requirements of the vast majority of products due to its ability to process more complex parts, so it has been widely used in metal processing factories.

[0003] During the operation of the spinning machine, the role of the spinning wheel is crucial. If the wear degree of the spinning wheel exceeds the reasonable range, it may lead to the production of defective products. To reduce the wear of the spinning wheel, existing spinning machines are usually equipped with a lubrication device. When it is detected that the spinning wheel needs lubrication, the lubrication device will automatically spray lubricating oil on the spinning wheel to prevent excessive wear of the spinning wheel.

[0004] However, when the spinning machine is running, the distribution of lubricating oil on the surface of the spinning wheel may not be obvious. Coupled with the high-speed rotation of the spinning wheel, the spinning wheel will throw off the lubricating oil on its surface during high-speed rotation, making it difficult for the operator to timely and accurately judge whether the spinning wheel needs to be replenished with lubricating oil. This may cause the over-worn spinning wheel to continue to be used, thus producing defective parts. Summary of the Invention

[0005] The purpose of the present invention is to provide a spinning machine that can timely and accurately judge whether the spinning wheel needs to be replenished with lubricating oil and slow down the wear of the spinning wheel.

[0006] Embodiments of the present invention are achieved through the following technical solutions: A spinning machine includes a spinning machine body, on which a spinning wheel is rotatably arranged. A moving cover is slidably arranged on the spinning machine body. The moving cover is arranged on the periphery of the spinning wheel. A first adsorption wheel is rotatably arranged in the moving cover. The first adsorption wheel is used to abut against the edge of the spinning wheel. The surface of the first adsorption wheel adhesively adsorbs the lubricating oil on the surface of the spinning wheel. A collecting belt and a driving roller are rotatably arranged on the moving cover. The collecting belt is wound around the driving roller. The side surface of the first adsorption wheel also abuts against the surface of the collecting belt. An image acquisition camera and an analysis control host are arranged on the moving cover. The acquisition end of the image acquisition camera faces the surface of the collecting belt. The image acquisition camera acquires the lubricating oil trace of the first adsorption wheel on the surface of the collecting belt. The image acquisition camera is electrically connected to the data acquisition end of the analysis control host. The analysis control host analyzes the change in the color depth of the lubricating oil trace on the surface of the collecting belt. A spray nozzle is arranged on the moving cover on the periphery of the spinning wheel. When the color depth of the lubricating oil trace on the surface of the collecting belt is lower than a preset color depth threshold, the analysis control host controls the spray nozzle to spray lubricating oil towards the spinning wheel.

[0007] Further, a connecting rod is telescopically arranged on the moving cover. The connecting rod is connected to the rotating shaft of the first adsorption wheel. A damping spring is sleeved on the connecting rod.

[0008] Further, a first scraping plate is arranged on the moving cover. The first scraping plate abuts against the edge of the first adsorption wheel.

[0009] Further, a second adsorption wheel is also rotatably arranged on the moving cover. The second adsorption wheel is distributed in a staggered manner with the first adsorption wheel. The second adsorption wheel is used to abut against the spinning wheel and also abuts against the surface of the collecting belt. The distance between the first adsorption wheel and the spinning wheel is less than the distance between the second adsorption wheel and the spinning wheel.

[0010] Further, a second scraping plate is arranged on the moving cover. The second scraping plate abuts against the surface of the collecting belt.

[0011] Further, the widths of the first adsorption wheel and the second adsorption wheel are different.

[0012] Further, a first support rod and a second support rod are arranged inside the moving cover. The top end of the connecting rod is slidably arranged at the end of the first support rod. A first abutting spring is arranged on the first support rod. A first end of the first abutting spring is fixedly connected to the first support rod, and a second end of the first abutting spring abuts against the connecting rod. The second support rod is parallel to the first support rod. A sliding block is slidably arranged at the end of the second support rod. The sliding block is connected to the rotating shaft of the second adsorption wheel. A second abutting spring is arranged on the second support rod. A first end of the second abutting spring is fixedly connected to the second support rod, and a second end of the second abutting spring abuts against the sliding block. A jacking block is arranged on the moving cover, and the jacking block alternately compresses the first abutting spring and the second abutting spring.

[0013] Further, a jacking rod is slidably arranged inside the moving cover. The jacking block is arranged on the jacking rod. The jacking rod is perpendicular to the first support rod and the second support rod. A driving rack is arranged at one end of the jacking rod. A driving motor is arranged inside the moving cover.

[0014] Further, a temperature sensor is also arranged on the moving cover, and the acquisition end of the temperature sensor faces the rotating wheel.

[0015] Further, a wiping block is also arranged on the second scraper. The wiping block abuts against the surface of the acquisition belt. The second scraper is closer to the starting end of the rotating direction of the acquisition belt relative to the wiping block.

[0016] The technical solution of the embodiment of the present invention has at least the following advantages and beneficial effects: 1. In the present invention, the first adsorption wheel abuts against the rotating wheel, adheres to and adsorbs the lubricating oil on the surface of the rotating wheel, and prints the lubricating oil on the surface of the acquisition belt. The image acquisition camera takes pictures of the lubricating oil traces on the surface of the acquisition belt. By analyzing and controlling the host computer, the color depth of the lubricating oil traces in the taken pictures is compared with the preset color depth threshold in real time. When the color depth of the lubricating oil traces is lower than the preset color depth threshold, the analysis and control host computer automatically drives the spray nozzle to spray lubricating oil on the rotating wheel, realizing automatic, timely and accurate judgment of whether the rotating wheel needs to be replenished with lubricating oil, and slowing down the wear of the rotating wheel; 2. In the present invention, a second adsorption wheel is respectively arranged on the moving cover, so that the distances between the second adsorption wheel and the first adsorption wheel relative to the rotating wheel are different. Whether the wear of the rotating wheel exceeds a reasonable range is judged according to the distance from the second adsorption wheel approaching the rotating wheel until it adheres to the lubricating oil. Once it exceeds the reasonable range, the rotating wheel stops working and is replaced; 3. By providing a first abutting spring, a second abutting spring, and a jacking block, when the jacking block compresses the first abutting spring or the second abutting spring, the relative positions of the first adsorption wheel and the second adsorption wheel with respect to the rotating wheel are alternately changed, making the detection result more accurate.

Detailed implementation mode

[0020] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. The components of the embodiments of the present invention usually described and illustrated in the drawings here can be arranged and designed in various different configurations.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed present invention, but merely represents the selected embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention. Embodiment

[0022] The following is further described in conjunction with specific embodiments. Refer to Figures 1 - 10 As shown, the present invention is a spinning machine. Refer to Figure 1 , including a spinning machine body 10. A plurality of driving devices 11 are provided on the spinning machine body 10. The output end of the driving device 11 is provided with a spinning wheel 12. The spinning wheels 12 of the plurality of driving devices 11 are simultaneously oriented towards the main shaft in the spinning machine body 10.

[0023] Refer to Figure 2 and Figure 3, a moving cover 20 is also slidably arranged on the driving device 11. The moving cover 20 is located at the side end of the rotating wheel 12. The moving cover 20 is arc-shaped, and the radian of the moving cover 20 is the same as the radian of the edge of the rotating wheel 12. The rotating wheel 12 rotates along the direction from the first end to the second end of the moving cover 20. A temperature sensor 21 is installed on the first end of the moving cover 20. The acquisition end of the temperature sensor 21 faces the edge of the rotating wheel 12. The temperature sensor 21 collects the temperature on the surface of the rotating wheel 12 and uploads the temperature data to the background computer. When the background computer analyzes that the temperature data exceeds the temperature threshold, it is determined that the rotating wheel 12 may be in a state of lacking lubricating oil, and the moving cover 20 is pushed towards the rotating wheel 12 by the power component. The power component in this embodiment can be a motor or a cylinder.

[0024] Refer to Figures 3 - 5 , a first support rod 22 and a second support rod 23 are parallelly installed at the middle part of the moving cover 20. Both the first support rod 22 and the second support rod 23 are parallel to the rotation axis of the rotating wheel 12. A first abutting spring 221 and a connecting rod 222 are installed on the first support rod 22. The first abutting spring 221 is sleeved on the first support rod 22, and the first end of the first abutting spring 221 is fixedly connected to the first support rod 22. The top end of the connecting rod 222 is fixedly installed with a connecting block 223. A sliding hole is formed in the connecting block 223, and the first support rod 22 passes through the sliding hole, so that the connecting rod 222 can slide along the first support rod 22. The second end of the first abutting spring 221 is fixedly connected to the connecting block 223. The first abutting spring 221 is in a compressed state, and the first abutting spring 221 pushes the sliding block 231 towards the end of the first support rod 22. A first auxiliary rod 224 is also installed on the moving cover 20. The first auxiliary rod 224 is parallel to the first support rod 22. A first auxiliary hole is also formed at the top end of the connecting block 223. The first auxiliary rod 224 passes through the first auxiliary hole to limit the relative rotation of the connecting rod 222 with respect to the first support rod 22.

[0025] Refer to Figure 3 and Figure 4 , the connecting rod 222 is a telescopic rod. An installation frame 225 is installed at the bottom end of the connecting rod 222. A first adsorption wheel 226 is rotatably installed in the installation frame 225. A damping spring 227 is also sleeved on the connecting rod 222. The two ends of the damping spring 227 respectively abut against the bottom end of the connecting block 223 and the top end of the installation frame 225. The first adsorption wheel 226 is used to abut against the edge of the rotating wheel 12. The first adsorption wheel 226 is a sponge wheel. When the first adsorption wheel 226 abuts against the rotating wheel 12, the first adsorption wheel 226 adsorbs the lubricating oil on the surface of the rotating wheel 12, and the more lubricating oil there is on the surface of the rotating wheel 12, the more lubricating oil the first adsorption wheel 226 adsorbs.

[0026] Refer to Figure 3 and Figure 5, a sliding block 231 is slidably arranged on the second support rod 23, and the sliding block 231 slides along the length direction of the second support rod 23. A fixing rod 232 is arranged at the bottom end of the sliding block 231, and the length of the fixing rod 232 is between the maximum length and the minimum length of the connecting rod 222. A second adsorption wheel 233 is rotatably installed at the bottom end of the fixing rod 232. The first adsorption wheel 226 and the first adsorption wheel 226 are arranged in a staggered manner, and the width of the second adsorption wheel 233 is greater than the width of the first adsorption wheel 226, so as to facilitate distinguishing the lubricating oil traces of the first adsorption wheel 226 and the second adsorption wheel 233. The second adsorption wheel 233 is used for abutting against the edge of the rotating wheel 12. The second adsorption wheel 233 is a sponge wheel. When the second adsorption wheel 233 abuts against the rotating wheel 12, the second adsorption wheel 233 adsorbs the lubricating oil on the surface of the rotating wheel 12. When the second adsorption wheel 233 moves towards the rotating wheel 12 and abuts against the rotating wheel 12, if the moving distance of the second adsorption wheel 233 is greater than or equal to a predetermined value, it is determined that the rotating wheel 12 has reached the degree of wear, and the operator is reminded that the rotating wheel 12 needs to be replaced.

[0027] Refer to Figure 3 and Figure 5 , a second holding spring 234 is also sleeved on the second support rod 23. The first end of the second holding spring 234 is fixedly connected to the rod body of the second support rod 23, and the second end of the second holding spring 234 abuts against the surface of the sliding block 231. The second holding spring 234 is in a compressed state, and the second holding spring 234 pushes the sliding block 231 to move towards the end of the second support rod 23. A second auxiliary rod 235 is also installed on the moving cover 20. The second auxiliary rod 235 is parallel to the second support rod 23. A second auxiliary hole is also opened at the top end of the sliding block 231, and the second auxiliary rod 235 passes through the second auxiliary hole to limit the relative rotation of the connecting rod 222 with respect to the second support rod 23.

[0028] Refer to Figure 3 , Figure 6 and Figure 7, a jacking rod 24 is also slidably mounted on the moving cover 20. The jacking rod 24 is perpendicular to the first support rod 22 and the second support rod 23, and both ends of the jacking rod 24 face the ends of the first support rod 22 and the second support rod 23 respectively. A jacking block 241 is convexly mounted on the jacking rod 24, and the jacking block 241 is used to abut against the connecting block 223 and the sliding block 231. A driving rack 242 is provided on the rod body of the jacking rod 24, a driving motor 25 is mounted on the moving cover 20, a driving gear 251 is mounted on the output shaft of the driving motor 25, and the driving gear 251 meshes with the driving rack 242. The driving motor 25 drives the jacking rod 24 to move, controls the jacking block 241 to abut against the connecting block 223 or the sliding block 231 respectively, compresses the first holding spring 221 or the second holding spring 234 respectively, changes the positions of the first adsorption wheel 226 and the second adsorption wheel 233 relative to the rotating wheel 12, and improves the accuracy of extracting the lubricating oil stock.

[0029] Referring to Figure 8 , a plurality of driving rollers 26 are also rotatably mounted on the moving cover 20, and a power motor is mounted on the end of one of the driving rollers 26, and the body of the power motor is fixedly connected to the moving cover 20. A collecting belt 27 is wound around the driving rollers 26. The plurality of driving rollers 26 are distributed according to preset positions, so that the first adsorption wheel 226 and the second adsorption wheel 233 can simultaneously abut against the surface of the collecting belt 27, and the lubricating oil traces left by the first adsorption wheel 226 and the second adsorption wheel 233 on the collecting belt 27 are parallelly distributed. When the lubricating oil on the rotating wheel 12 is insufficient, the lubricating oil traces left by the first adsorption wheel 226 and the second adsorption wheel 233 on the collecting belt 27 are relatively light.

[0030] Referring to Figures 3 - 5 , a first scraper 28 is arranged in the moving cover 20 along the direction parallel to the rotation axis of the rotating wheel 12. The number of the first scrapers 28 is two. The two first scrapers 28 are respectively pressed tightly against the circumferences of the first adsorption wheel 226 and the second adsorption wheel 233, and the minimum distance between the rotation axis of the first adsorption wheel 226 or the second adsorption wheel 233 and the first scraper 28 is less than the radius of the first adsorption wheel 226 or the second adsorption wheel 233. The high end of the first scraper 28 is close to the circumference of the first adsorption wheel 226 or the second adsorption wheel 233, and the low end of the first scraper 28 is far from the circumference of the first adsorption wheel 226 or the second adsorption wheel 233. The first scraper 28 squeezes the first adsorption wheel 226 or the second adsorption wheel 233, so that the lubricating oil inside the first adsorption wheel 226 and the second adsorption wheel 233 is extruded, so as to make the first adsorption wheel 226 or the second adsorption wheel 233 abut against the rotating wheel 12 again, and avoid the influence of the residual lubricating oil on the accuracy of the lubricating oil traces left on the collecting belt 27. And the extruded lubricating oil can be collected or fall back onto the surface of the rotating wheel 12 under the action of gravity.

[0031] Referring to Figure 8 andFigure 9 Inside the moving cover 20, a second scraper 29 is installed. The edge of the second scraper 29 abuts against the surface of the collecting belt 27. The second scraper 29 is located at the end of the collecting belt 27 along the rotation direction. And the second scraper 29 is inclined. A collecting box 210 is installed below the lower end of the second scraper 29. The collecting box 210 is used to collect the lubricating oil scraped off from the collecting belt 27, so that the clean collecting belt 27 can be recycled by the first adsorption wheel 226 or the second adsorption wheel 233.

[0032] Refer to Figure 10 On the driving device 11, a support frame 211 is installed. An image acquisition camera 212 is fixedly installed on the support frame 211. The acquisition end of the image acquisition camera 212 faces the surface of the collecting belt 27, and photographs the lubricating oil traces left by the first adsorption wheel 226 and the second adsorption wheel 233 on the surface of the collecting belt 27. An analysis and control host is installed on the body 10 of the spinning press. The data input end of the analysis and control host is electrically connected to the image acquisition camera 212. The analysis and control host acquires the image photographed by the image acquisition camera 212, analyzes the color depth of the lubricating oil traces in the image, and compares the color depth with a preset color depth threshold. When the color depth is less than the preset color depth threshold, the analysis and control host will determine that the spinning wheel 12 is in a state of lacking lubricating oil.

[0033] Refer to Figure 10 Inside the moving cover 20, a spray nozzle 213 is also installed. The spray nozzle 213 is controlled by the analysis and control host. When the analysis and control host determines that the spinning wheel 12 is in a state of lacking lubricating oil, the analysis and control host drives the spray nozzle 213 to spray lubricating oil towards the spinning wheel 12.

[0034] The working process of this embodiment is as follows: During the working process of the spinning press, the temperature sensor 21 continuously acquires the temperature of the spinning wheel 12. When the background computer detects that the temperature of the spinning wheel 12 exceeds the temperature threshold, the power assembly is used to push the moving cover 20 closer to the edge of the spinning wheel 12. The first adsorption wheel 226 first abuts against the surface of the spinning wheel 12. The first adsorption wheel 226 absorbs the lubricating oil on the surface of the spinning wheel 12 and leaves lubricating oil traces on the surface of the collecting belt 27. The image acquisition camera 212 photographs the image of the lubricating oil traces left by the first adsorption wheel 226 on the collecting belt 27. The analysis and control host analyzes the color depth of the lubricating oil traces to determine whether the spinning wheel 12 is in a state of lacking lubricating oil. When the spinning wheel 12 is in a state of lacking lubricating oil, the analysis and control host controls the spray nozzle 213 to spray lubricating oil on the spinning wheel 12.

[0035] When the second adsorption wheel 233 abuts against the rotating wheel 12 and leaves a lubricating oil trace on the collecting belt 27, the wear degree of the rotating wheel 12 and whether it needs to be replaced are judged according to the moving distance of the second adsorption wheel 233 moving towards the rotating wheel 12. When the moving distance of the second adsorption wheel 233 is greater than or equal to a predetermined value, it is determined that the rotating wheel 12 has reached the wear degree, and the operator is reminded that the rotating wheel 12 needs to be replaced.

[0036] Control the driving motor 25 to act to drive the jacking rod 24 to move, and drive the jacking block 241 to compress the first jacking spring 221 or the second jacking spring 234 respectively, so as to change the positions of the first adsorption wheel 226 and / or the second adsorption wheel 233 relative to the rotating wheel 12, and collect the lubricating oil at different positions of the rotating wheel 12. And during the process of changing the positions of the first adsorption wheel 226 and / or the second adsorption wheel 233 relative to the rotating wheel 12, the moving cover 20 is temporarily moved away from the rotating wheel 12. After the positions of the first adsorption wheel 226 and / or the second adsorption wheel 233 change, the moving cover 20 moves towards the rotating wheel 12 again.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
