Description

Technical Field

[0001] This invention relates to the field of turning technology, and more specifically to a turning device for processing police shields. Background Technology

[0002] Police shields are essential protective equipment for police officers during operations, and their quality and performance directly impact their safety. With technological advancements and the diversification of criminal methods, the requirements for the protective performance and structural strength of police shields are increasingly stringent, making their manufacturing precision crucial. Turning, as a key process in police shield manufacturing, significantly influences the shield's shape and dimensions.

[0003] Existing turning equipment often struggles to flexibly adjust to the different shapes of police shields when positioning and clamping them, leading to insecure clamping or inaccurate clamping positions, which affects the precision and quality of the turning process. For example, for some irregularly shaped police shields, traditional clamping methods may not be able to adapt well to their contours, easily causing the workpiece to loosen or shift during the turning process.

[0053] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments. Examples of the invention are given for illustrative and descriptive purposes only and are not intended to be exhaustive or to limit the invention to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described to better illustrate the principles and practical application of the invention and to enable those skilled in the art to understand the invention and design various embodiments with various modifications suitable for a particular purpose.

[0054] Example 1: Please refer to Figures 1-4, Figure 7 , Figure 8 In this embodiment, a turning device for processing police shields is provided. The turning device for processing police shields includes: a turning frame 1; the turning frame 1 is axially symmetrically mounted with two sets of processing positioning mechanisms 2; the processing positioning mechanisms 2 are used to clamp and position the police shield workpiece 5, and can freely adjust the height position, lateral position and longitudinal position according to the shape of the police shield workpiece 5.

[0055] The clamping position of the machining positioning mechanism 2 is provided with a shifting component 22 for adjusting the position and angle of the police shield workpiece 5 on the turning frame 1; the shifting component 22, in conjunction with the machining positioning mechanism 2, can control the position of the police shield workpiece 5 inside the turning frame 1 after placement. The machining positioning mechanism 2 and its shifting component 22 each have four units for clamping and positioning the police shield workpiece 5, and the shifting component 22 is assembled inside the positioning clamping unit.

[0056] The processing positioning mechanism 2 includes a positioning cylinder 201 rotatably mounted on the turning frame 1, and four sets of adjusting plates 202 are fixedly assembled on the inner side of the positioning cylinder 201, and an inner square plate 21 is fixedly provided on one end of the inner side of each of the four sets of adjusting plates 202; each of the four sets of adjusting plates 202 is equipped with a clamping and positioning unit for clamping and positioning the police shield workpiece 5; the four sets of clamping and positioning units can be adjusted along the height position of the adjusting plate 202, and can also move along the inner side of the adjusting plate 202 to adjust the clamping position of the police shield workpiece 5;

[0057] It also includes a drive unit 3 installed inside the turning frame 1 and synchronously driving the machining positioning mechanism 2 to rotate; the two sets of machining positioning mechanisms 2 can be driven to rotate simultaneously through the drive unit 3 to fix and rotate the police shield workpiece 5 that is clamped and positioned.

[0058] The drive unit 3 includes a first helical tooth ring 301 fixedly installed on the bottom outer wall of the positioning cylinder 201 in a processing positioning mechanism 2, and a second helical tooth ring 302 fixed on the top outer wall of the positioning cylinder 201 in another processing positioning mechanism 2, and the first helical tooth ring 301 is meshed with a first helical gear 303.

[0059] A drive rod is fixedly assembled at the center of the first helical gear 303, and a second helical gear 304 that meshes with the second helical gear ring 302 is fixedly provided on the outer wall of the drive rod.

[0060] The bottom end of the drive rod is connected to a servo motor 305 that is fixedly installed on the inner side wall of the turning frame 1;

[0061] The servo motor 305 is used to actively drive the drive rod to rotate, and the rotating drive rod synchronously drives the first helical gear 303 and the second helical gear 304 to rotate synchronously, so that the first helical gear 303 meshes with the first helical gear ring 301 and the second helical gear 304 meshes with the second helical gear ring 302.

[0062] The two sets of processing and positioning mechanisms 2 are synchronized and rotate in the same direction along the inner side of the turning frame 1 to rotate the police shield workpiece 5.

[0063] Another set of the processing positioning mechanism 2 has a positioning cylinder frame 201 with a load-bearing shaft ring 6 rotatably mounted at the bottom, and the bottom end of the load-bearing shaft ring 6 is sealed with a waste liquid tank 7 for collecting cooling water and its waste residue.

[0064] The waste liquid tank 7 is equipped with an angled filter screen 9 inside;

[0065] The filter screen 9 is closely attached to a bottom scraper 13 for scraping and cleaning waste residue, and a transmission rod 12 is hinged to the middle of the bottom scraper 13. A fixing rod 11 is fixed to the top of the transmission rod 12, and the fixing rod 11 is fixedly set to the inner wall of the positioning cylinder 201 of another set of processing positioning mechanisms 2.

[0066] When the positioning cylinder frame 201 rotates, the transmission rod 12 connected by the fixed rod 11 drives the bottom scraper 13 to scrape and rotate along the filter screen 9, which is beneficial for cleaning the residual metal waste on the filter screen 9.

[0067] Furthermore, two sets of return springs 14 are installed between the bottom scraper 13 and the transmission rod 12. When the bottom scraper 13 rotates, the tilt angle with the filter screen 9 can be automatically adjusted by the return springs 14.

[0068] The waste liquid tank 7 has a slag discharge trough 15 at the top for discharging waste residue. A waste residue box 16 is sealed on the outside of the slag discharge trough 15. A drain pipe 8 is connected through the bottom side wall of the waste liquid tank 7. A controller 10 is installed on the outer wall of the turning frame 1.

[0069] Example 2: Please refer to Figure 7 , Figure 10 In this embodiment, a machining positioning mechanism 2 is provided in the turning device for processing police shields;

[0070] An inner baffle 203 is fixed in the middle of the adjusting plate 202, and a limiting groove 204 is provided in the middle of the inner baffle 203. An outer frame groove 205 is provided between the inner baffle 203 and the adjusting plate 202. A frame groove block 206 is slidably provided on the inner side of the outer frame groove 205 and sleeved on the outside of the inner baffle 203. A screw 209 is provided on one inner wall of the frame groove block 206 and is rotatably installed on the inner side of the outer frame groove 205.

[0071] A vertical rod frame 207 is movably provided inside the frame slot block 206, and a screw 208 that is screwed to the frame slot block 206 is rotatably installed inside the vertical rod frame 207. A bottom frame 210 is fixed to one end of the vertical rod frame 207, and a fixing plate 215 is fixed to the other end of the vertical rod frame 207.

[0072] One end of the screw 208 rotates through the inside of the base frame 210 and is connected to a servo motor 212;

[0073] The servo motor 212 is used to actively drive the screw 208 to rotate, and the rotating screw 208 drives the vertical rod frame 207 to spiral along the frame slot block 206.

[0074] The vertical rod frame 207, through the screw 209 of the frame slot block 206, can drive the clamping and positioning unit to move along the adjustment plate 202.

[0075] Furthermore, the clamping and positioning unit can be moved up and down along the frame slot block 206 via the helical drive of screw 208 to adjust its height position;

[0076] The positioning and clamping unit includes a vertical slide rod 211 that is slidably disposed on the inner walls of both sides of the bottom frame 210, and a load-bearing plate 213 is fixed at one end of the vertical slide rod 211. An electric hydraulic rod 214 is installed between the load-bearing plate 213 and the bottom frame 210.

[0077] The other end of the vertical slide bar 211 is fixedly provided with a clamping cylinder 216, and the end of the clamping cylinder 216 away from the vertical slide bar 211 is fixedly equipped with a clamping rubber 217 that contacts the police shield workpiece 5 when clamping.

[0078] During the retraction process, the electric hydraulic rod 214 shortens the distance between the load-bearing plate 213 and the bottom frame 210. The moving load-bearing plate 213 moves the two sets of vertical sliding rods 211, causing the vertical sliding rods 211 to push the distance between the clamping cylinder 216 and the fixed plate 215. This facilitates adjustment so that the clamping rubber 217 contacts and clamps the police shield workpiece 5, or moves away from the police shield workpiece 5 so that the shifting component 22 makes alternating contact.

[0079] Example 3: Please refer to Figures 5-6 , Figure 7 , Figure 11 , Figure 12 In this embodiment, a shifting component 22 is provided in the turning device for processing police shields;

[0080] The shifting assembly 22 includes a steering rod 2201 rotatably mounted at the center of the fixed plate 215, and the steering rod 2201 is slidably mounted at the center of the clamping cylinder 216; an assembly frame 2205 is fixedly mounted at the end of the steering rod 2201 away from the fixed plate 215, a limiting disc 2206 is fixedly mounted on the assembly frame 2205, and four sets of adjusting balls 2207 are rotatably arranged inside the limiting disc 2206;

[0081] Both ends of the inner side of the assembly frame 2205 are rotatably mounted with transmission rollers 2208, and a transmission belt that contacts the turning ball 2207 is sleeved on the outer side between the two transmission rollers 2208. Worm gears 2209 are fixedly mounted in the middle of the two transmission rollers 2208, and worm gears 2209 mesh with worms 2210. One end of worm gears 2210 is connected to a bidirectional motor 2211. Worm gears 2202 are fixedly mounted on the outer wall of the steering rod 2201 outside the clamping cylinder 216, and worm gears 2202 mesh with worms 2203. Worms 2203 is connected to a servo motor 2204 fixedly mounted on the fixed plate 215.

[0082] The bidirectional motor 2211 is used to actively drive the second worm gear 2210 to rotate, and the rotation of the second worm gear 2210 can mesh with and rotate the second worm wheel 2209, so that the second worm wheel 2209 drives the corresponding transmission roller 2208 to rotate. When the transmission roller 2208 rotates, the transmission belt on it moves along with it. Through the friction of the transmission belt on the adjusting ball 2207, the adjusting ball 2207 can adjust the trajectory of the police shield workpiece 5 in contact.

[0083] When adjusting the steering angle of the rotating ball 2207, the servo motor 3 2204 is started. The start of the servo motor 3 2204 can drive the worm gear 1 2203 to rotate. The rotation of the worm gear 1 2203 meshes with the worm wheel 1 2202 to rotate. The rotating worm wheel 1 2202 adjusts the angle of the steering rod 2201 on the fixed plate 215, which is beneficial for adjusting the movement and placement of the rotating ball 2207.

[0084] Example 4: Please refer to Figure 6 , Figure 9 , Figure 11 In this embodiment, an inner square plate 21 is provided in the turning device for processing police shields;

[0085] Four driven rods 2104, each integrally fixed to four screws 209, are rotatably mounted inside the inner square plate 21. A driven helical gear 2103 is fixedly mounted at the end of each driven rod 2104 away from the screws 209. The driven helical gear 2103 meshes with a driving helical gear 2102. A servo motor 2105 is connected to the top of the driving helical gear 2102. The servo motor 2105 is fixedly mounted on the inner wall of the inner square plate 21, and an assembly plate 2101, detachably mounted to the bottom of the driving helical gear 2102, is rotatably mounted to it. When the servo motor 2105 rotates, it drives the driving helical gear 2102 to rotate. The rotating driving helical gear 2102 meshes with the four driven helical gears 2103, causing the corresponding driven rod 2104 to drive the screws 209 to rotate.

[0086] The rotating screw 209 can provide helical drive to the frame slot block 206, which facilitates the movement of the frame slot block 206.

[0087] Example 5: Please refer to Figure 7 In this embodiment, a turning unit 4 is provided in the turning device for processing police shields;

[0088] The turning device for processing police shields also includes a turning unit 4 for turning police shield workpiece 5;

[0089] The turning frame 1 is fixedly provided with a slot for assembling the turning unit 4 in the middle.

[0090] The turning unit 4 includes an extension rod 401 slidably disposed inside the turning frame 1, and a turning tool 407 is detachably mounted on one end of the extension rod 401; a screw 403 is internally helically driven at the other end of the extension rod 401, and one end of the screw 403 rotatably passes through the inner wall of the turning frame 1 and is connected to a servo motor 404; when the servo motor 404 rotates, it drives the screw 403 to rotate actively, and the rotation of the screw 403 helically drives the extension rod 401, causing the extension rod 401 to extend the screw 403 to move inside the turning frame 1, which facilitates the adjustment of the position between the turning tool 407 and the police shield workpiece 5; a vertical slide is mounted on the outside of the servo motor 404, and the vertical slide is vertically slidably disposed between the vertical slide and the turning frame 1, and a vertical groove corresponding to the movement of the screw 403 is opened on the inner wall of the turning frame 1;

[0091] The extension rod 401 has a through groove in the middle, and a screw barrel 402 is slidably disposed inside the groove in an angle-locked state. Inside the screw barrel 402, a screw 405 is rotatably mounted on the inner side of the turning frame 1. The top of the screw 405 rotatably passes through the outer side of the turning frame 1 and is connected to a servo motor 406. When the servo motor 406 rotates, it drives the screw 405 to rotate. The rotating screw 405 can drive the screw barrel 402 to rotate along the screw 405, which can drive the extension rod 401 to adjust its height, which is beneficial for adjusting the height position of the turning tool 407.

[0092] According to the above embodiments, the working principle of this invention is as follows:

[0093] In the three-dimensional position adjustment, when adjusting the horizontal and height, servo motor 2105 drives the active helical gear 2102, which in turn drives the screw 209 to rotate through the driven helical gear 2103, causing the frame slot block 206 to slide horizontally along the outer frame slot 205; at the same time, servo motor 212 drives the screw 208, which drives the vertical rod frame 207 to move up and down along the frame slot block 206, thereby realizing the horizontal and height position adjustment of the clamping and positioning unit.

[0094] Angle and longitudinal fine adjustment: In the shifting assembly 22, the bidirectional motor 2211 drives the second worm gear 2210, which drives the transmission roller 2208 to rotate through the second worm wheel 2209. The transmission belt friction adjustment ball 2207 pushes the workpiece to move longitudinally and adjust the angle; the servo motor 3 2204 drives the first worm gear 2203, which rotates the steering rod 2201 through the first worm wheel 2202 to further precisely adjust the angle of the adjustment ball 2207;

[0095] When the electric hydraulic rod 214 retracts, it pushes the load-bearing plate 213 to move the vertical slide rod 211 and the clamping cylinder 216, so that the clamping rubber 217 is in close contact with the workpiece surface, thus achieving synchronous clamping of the four sets of clamping and positioning units.

[0096] The driving rotation principle is that the driving unit 3 drives the driving rod to rotate through the servo motor 305, which drives the first helical gear 303 and the second helical gear 304 to rotate synchronously. The first helical gear 303 meshes with the first helical ring gear 301, and the second helical gear 304 meshes with the second helical ring gear 302, so that the two sets of machining positioning mechanisms 2 rotate synchronously and in the same direction along the inner side of the turning frame 1, driving the clamped workpiece to make uniform circular motion, providing a rotational basis for turning.

[0097] Turning machining principle, turning tool 407 position adjustment, horizontal movement: servo motor 5 404 drives screw 3 403 to rotate, extension rod 401 slides horizontally along the inner side of turning frame 1, adjusting the horizontal distance between turning tool 407 and workpiece;

[0098] Height adjustment: Servo motor 406 drives screw 405 to rotate, which in turn drives extension rod 401 to move vertically through screw barrel 402, thus achieving height positioning of turning tool 407;

[0099] During turning, when the workpiece rotates under the drive unit 3, the turning tool 407 turns the workpiece surface at a preset position to complete the contour forming or surface treatment.

[0100] The principle of waste liquid and waste residue treatment is as follows: collection and filtration. The cooling water and waste residue generated during processing fall into the waste liquid tank 7 through the load-bearing shaft ring 6. After being filtered by the inclined filter screen 9, the waste liquid is discharged from the drain pipe 8, and the waste residue remains on the surface of the filter screen 9.

[0101] When the positioning cylinder 201 rotates, the fixed rod 11 drives the bottom scraper 13 to rotate along the filter screen 9 through the transmission rod 12, scraping off the waste residue and pushing it into the slag discharge trough 15 and into the waste residue box 16; the reset spring 14 ensures that the bottom scraper 13 is always in close contact with the filter screen 9 and adapts to its tilt angle.

[0102] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
