Description

Technical Field

[0001] This application relates to the field of steel roller processing technology, and specifically to a steel roller processing device. Background Technology

[0002] In ceramic machining, the ceramic firing equipment and post-kiln equipment on the production line require a large number of steel rollers for automated connection and long-distance transportation. In the processing of steel rollers, the edges of the steel rollers need to be chamfered and deburred to prevent the steel rollers from scratching the ceramic products during use and to ensure the safety of transportation.

[0003] Deburring equipment for steel rollers often employs a double-head chamfering machine. This machine clamps and fixes the steel roller on a worktable, and then uses motors at both ends to drive the cutting tools to rotate, thereby simultaneously chamfering both ends of the steel roller. However, existing steel rollers used for ceramic machinery processing and transportation come in various shapes, including stepped columnar and tubular shapes. Existing double-head chamfering machines only have a single clamping function, namely, abutting clamping for stepped columnar shapes. Abutting clamping is not suitable for tubular steel rollers. Therefore, this invention proposes a processing device with multi-shape clamping for steel rollers. Summary of the Invention

[0004] The purpose of this application is to provide a steel roller processing device in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application specifically adopts the following technical solution:

[0008] The cutting assembly includes a mounting block fixedly connected to a movable stage, a rotating tube rotatably installed inside the mounting block, and a cutting head detachably connected to the opposite ends of the two rotating tubes. A drive motor for driving the rotating tubes to rotate is mounted on the movable stage.

[0009] The clamping mechanism includes a positioning plate fixedly connected to the opposite ends of two moving platforms. A horizontal tube is slidably installed through the positioning plate and is movably inserted into the rotating tube. One end of the horizontal tube that movably passes through the rotating tube is provided with a wrapping clamping component for clamping the end of the steel roller. A pneumatic support component for abutting against and supporting the inner wall of the steel roller is also installed at the end of the horizontal tube.

[0010] The feeding mechanism is installed on the frame and vertically positioned between two positioning seats to push and lift the steel rollers between the two horizontal tubes.

[0011] Furthermore, a slide rail is fixedly connected to the top of the positioning seat, and the moving platform is slidably installed in the slide rail. Mounting plates are fixedly connected to the opposite ends of the two slide rails. A cylinder push rod is fixedly connected to the mounting plate. The output end of the cylinder push rod is fixedly connected to the moving platform. Two guide rods that slide through the mounting plate are fixedly connected to the moving platform.

[0012] Furthermore, each of the two rotating tubes has a polygonal annular groove at its opposite ends. The cutting head includes a polygonal annular plate that is slidably inserted into the polygonal annular groove. The rotating tube has multiple fixing bolts threaded through the polygonal annular plate on its side. The ends of the polygonal annular plate are connected to multiple beveled cutters in a circumferential array.

[0013] Furthermore, the bevel cutter includes multiple connecting blocks fixedly connected to the end of the polygonal ring plate. Both sides of the connecting blocks are constructed with beveled grooves, and blades are detachably connected to the beveled grooves by bolts.

[0014] Furthermore, the rotating tube includes two oppositely arranged connecting discs, and a rotating through-mounting block ring is fixedly connected between the two connecting discs. Two support bearings are fixedly connected inside the ring, and the horizontal tube slides through the two support bearings. A retaining ring is constructed in the middle of the horizontal tube, and a return spring is connected between the retaining ring and the inner ring of one of the support bearings.

[0015] Furthermore, the positioning plate includes a vertical plate, and a baffle is provided on the side of the vertical plate opposite to the mounting block. Two adjusting knobs with threads passing through the baffle are rotatably connected to the vertical plate, and the opposite ends of the two horizontal tubes are each constructed with stepped tubes that slide through the baffle.

[0016] Furthermore, each of the two horizontal tubes has a conical groove communicating with its interior at its opposite ends. The wrapping clamping member includes a sliding tube that is slidably inserted into the horizontal tube. One end of the sliding tube is fixedly connected to three fan-shaped clamping blocks arranged in a circumferential array and inserted into the conical groove. A cylindrical groove for wrapping the steel roller is constructed between the three fan-shaped clamping blocks, and a gap is constructed between each pair of fan-shaped clamping blocks.

[0017] Furthermore, the inner wall of the horizontal tube has an annular cavity, one end of which has a flow hole communicating with the inner hole of the horizontal tube. The circumferential side of the slide tube has multiple air inlets and outlets communicating with the flow hole. A one-way air valve is installed in the port of the slide tube. The pneumatic support includes multiple T-shaped support plates slidably inserted into the outer wall of the horizontal tube. The T-shaped support plates are arranged in a circumferential array and a rubber plunger is fixedly connected to one end facing the inside of the horizontal tube. The inner wall of the annular cavity has multiple movable grooves for wrapping the rubber plunger. The end of the rubber plunger is fixedly connected to the edge of the movable groove with an elastic sealing piece.

[0018] Furthermore, the outer wall of the sliding tube is constructed with a circumferential array of multiple strip grooves, and the inner wall of the horizontal tube is fixedly connected with multiple guide positioning blocks that are slidably inserted into the strip grooves.

[0019] Furthermore, the feeding mechanism includes a mounting base fixedly connected to the frame, a movable block slidably mounted on the mounting base, a cylinder push rod II with its output end connected to the mounting base fixedly connected to the mounting base, an inclined material holding rack fixedly connected to the frame and covering the mounting base, L-shaped grooves being constructed on both sides of the inclined material holding rack, a chain plate hinged to the movable block and slidably mounted in the L-shaped groove, and two Y-shaped lifting rods fixedly connected to the other end of the chain plate.

[0020] The beneficial effects of this application are as follows:

[0021] This application, by setting a movable stage on two positioning seats and using a cylinder push rod to move the movable stage, allows the end of the wrapping clamp on the movable stage to abut and clamp the two ends of the stepped steel rod, and also allows the wrapping clamp to wrap and clamp the end of the steel rod. Compared with abutment clamping, the wrapping clamping has a larger and more stable contact surface, which facilitates the chamfering operation on the stepped section of the steel rod. The setting of a gas support component can use air pressure to support and position the tubular steel rod on the inner wall, which facilitates the chamfering and deburring treatment of the end of the steel rod, thus improving the functionality and applicability of the device.

Detailed Implementation

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0035] like Figures 1-4 As shown, one embodiment of this application discloses a steel roller processing apparatus, comprising:

[0036] The frame 1 has two opposing positioning seats 101 fixedly connected to it. Each positioning seat 101 is slidably mounted with a moving platform 102, which can move along the length of the positioning seat 101.

[0037] The cutting assembly 2 includes a mounting block 201 fixedly connected to the moving table 102. A rotating tube 202 is rotatably installed inside the mounting block 201. A cutting head 203 is detachably connected to the opposite ends of the two rotating tubes 202. A drive motor 204 for driving the rotating tubes 202 to rotate is installed on the moving table 102. The drive motor 204 can drive the rotating tubes 202 to rotate axially, thereby realizing the function of rotational cutting.

[0038] The clamping mechanism 3 includes positioning plates 301 fixedly connected to the opposite ends of two moving platforms 102. A horizontal tube 302 is slidably installed through each positioning plate 301 and movably inserted into the rotating tube 202. One end of the horizontal tube 302 movably penetrates the rotating tube 202 and is provided with a clamping member 303 for clamping the end of the steel roller. A pneumatic support member 304 for abutting against and supporting the inner wall of the steel roller is also installed at the end of the horizontal tube 302. The horizontal tube 302 movably penetrates the interior of the rotating tube 202 but slidably penetrates the positioning plates 301. The positioning plate 301 can limit the rotation of the horizontal tube 302. Therefore, when the rotating tube 202 rotates, it will not drive the horizontal tube 302 to rotate. The rotating tube 202 can limit and support the position of the horizontal tube 302. When it is necessary to clamp the ends of the stepped steel rod, the movement of the moving table 102 can be used to bring the two wrapping clamping parts 303 closer together to clamp the two ends of the stepped steel rod. This makes it easier for the rotating tube 202 to drive the cutting head 203 to clamp the steel rod under the drive of the drive motor 204. The end edges are chamfered and deburred. The clamping component 303 can also clamp the end of the steel rod, facilitating the chamfering and deburring of the stepped edge of the steel rod by the cutting head 203 when the rotating tube 202 is rotating. When replacing the tubular steel rod, the pneumatic support component 304 can be used to position the inner wall of the tubular steel rod against the wall. Compared with the traditional end clamping, the contact surface is larger and the positioning is more stable, thus facilitating the chamfering and deburring of the end edge of the tubular steel rod by the cutting head 203. The deburring process increases the functionality and applicability of the device. It should be noted that the rotating tube 202 does not change position relative to the moving table 102, but can only rotate axially. When the two horizontal tubes 302 are clamped at both ends of the steel rod by the wrapping clamp 303 or the pneumatic support 304, the moving table 102 moves closer to each other again, which allows the cutting head 203 on the rotating tube 202 to move relative to the horizontal tube 302, thereby realizing the contact operation between the cutting head 203 and the edge of the steel rod end, ensuring the smooth progress of the chamfering process.

[0039] The feeding mechanism 4 is installed on the frame 1 and vertically positioned between the two positioning seats 101. It is used to push and lift the steel rollers between the two horizontal tubes 302. The feeding mechanism 4 is mainly used to automatically lift the arranged and transported steel rollers between the two horizontal tubes 302 so that the wrapping clamps 303 or pneumatic support members 304 on the horizontal tubes 302 can accurately clamp and limit the steel rollers.

[0040] like Figure 2 As shown, in some embodiments, a slide rail 1011 is fixedly connected to the top of the positioning seat 101, and the moving stage 102 is slidably installed in the slide rail 1011. Mounting plates 1012 are fixedly connected to the opposite ends of the two slide rails 1011. A cylinder push rod 1013 is fixedly connected to the mounting plate 1012. The output end of the cylinder push rod 1013 is fixedly connected to the moving stage 102. Two guide rods 1014 that slide through the mounting plate 1012 are fixedly connected to the moving stage 102. The cylinder push rod 1013 can be used to control the two moving stages 102 to move along the length direction of the slide rail 1011, while the guide rods 1014 are used to guide and limit the movement of the moving stage 102, so as to facilitate its deviation and improve the clamping accuracy of the device.

[0041] like Figure 5 As shown, in some embodiments, the opposite ends of the two rotating tubes 202 are each constructed with a polygonal annular groove 6. The cutting head 203 includes a polygonal annular plate 2031 slidably inserted into the polygonal annular groove 6. Both the polygonal annular groove 6 and the polygonal annular plate 2031 are hexagonal, which facilitates the synchronous rotation of the cutting head 203 by using the rotating tubes 202. The side of the rotating tube 202 is threaded with multiple fixing bolts 2032 that penetrate the polygonal annular plate 2031. The fixing bolts 2032 can be used to connect and disconnect the polygonal annular plate 2031. Multiple beveled cutters 2033 are connected in a circumferential array at the end of the polygonal annular plate 2031. The plug-in connection facilitates the replacement of the cutting head 203 as a whole, so as to adapt to the chamfering operation of steel rods of different sizes.

[0042] like Figure 6As shown, in some embodiments, the bevel cutter 2033 includes multiple connecting blocks 20331 fixedly connected to the end of the polygonal ring plate 2031. Both sides of the connecting blocks 20331 are constructed with beveled grooves 20332. Blades 20333 are detachably connected to each beveled groove 20332 via bolts. The inclination angle of the beveled groove 20332 is the beveling angle. The beveled grooves 20332 increase the tightness of the connection with the blades 20333, preventing the blades 20333 from detaching and improving the safety of the device. When a blade 20333 is damaged, only the individual blade 20333 can be removed and replaced without replacing the entire polygonal ring plate 2031, improving convenience. It should be noted that the two beveled grooves 20332 on the connecting block 20331 are arranged opposite each other. Therefore, two blades 20333 can be set on one connecting block 20331 to simultaneously bevele the outer and inner edges of the tubular steel rod, improving the functionality of the device and increasing the beveling efficiency.

[0043] like Figure 4 , Figure 5 and Figure 7 As shown, in some embodiments, the rotating tube 202 includes two oppositely arranged connecting discs 2021. A ring cylinder 2022 that rotatably passes through the mounting block 201 is fixedly connected between the two connecting discs 2021. Two support bearings 2023 are fixedly connected inside the ring cylinder 2022. The horizontal tube 302 slides through the two support bearings 2023. The position of the horizontal tube 302 can be limited by the two support bearings 2023, thereby limiting the height of the horizontal tube 302 by the rotating tube 202 to ensure clamping accuracy. A retaining ring 3021 is constructed in the middle of the horizontal tube 302. A return spring 3022 is connected between the retaining ring 3021 and the inner ring of one of the support bearings 2023. Because the inner ring of the support bearing 2023 and the horizontal tube 302 are fixedly connected, the horizontal tube 302 can be fixedly connected to the ring cylinder 2021. 02 Contact setting: When the rotating tube 202 rotates, it only drives the outer ring of the support bearing 2023 to rotate, without affecting the inner ring. Therefore, the inner ring and the retaining ring 3021 can remain stationary. When the clamping component 303 or the pneumatic support component 304 clamps the steel rod, and you want to perform chamfering work, you can use the moving table 102 to move closer to each other again, so that the rotating tube 202 moves relative to the horizontal tube 302. At this time, the return spring 3022 is compressed, thereby realizing the contact between the cutting head 203 and the end of the steel rod, which facilitates the chamfering cutting work. This coaxial clamping cutting method is safer than the traditional vertical feed cutting, and can ensure coaxiality and improve cutting accuracy.

[0044] like Figures 7-8As shown, in some embodiments, the positioning plate 301 includes a vertical plate 3011. A baffle 3012 is provided on the side of the vertical plate 3011 opposite to the mounting block 201. Two adjusting knobs 3013 with threads passing through the baffle 3012 are rotatably connected to the vertical plate 3011. The rotation of the two adjusting knobs 3013 allows them to engage with the baffle 3012, thereby adjusting the distance between the baffle 3012 and the vertical plate 3011. The opposite ends of the two horizontal tubes 302 are each equipped with a sliding section that passes through the baffle 3012. Regarding the stepped tube 3023, it should be noted that the horizontal tube 302 slides through the vertical plate 3011, and the outer diameter of the stepped tube 3023 is smaller than that of the horizontal tube 302. Therefore, after the connected end of the stepped tube 3023 and the horizontal tube 302 moves a certain distance, it will abut against the baffle 3012. This limits the distance that the horizontal tube 302 moves relative to the rotating tube 202. On the one hand, it can prevent excessive movement that would cause the cutting head 203 to feed too much. On the other hand, the abutment of the baffle 3012 can ensure the stability of the positioning of the steel rod.

[0045] like Figures 9-10 As shown, in some embodiments, each of the two horizontal tubes 302 has a conical groove 3024 communicating with its interior at its opposite ends. The clamping member 303 includes a sliding tube 3031 slidably inserted into the horizontal tube 302. One end of the sliding tube 3031 is fixedly connected to three fan-shaped clamps 3032 arranged in a circumferential array and inserted into the conical groove 3024. The end of the sliding tube 3031 connected to the fan-shaped clamps 3032 is closed, while the other end is open. A cylindrical groove 3033 for wrapping the steel roller is constructed between the three fan-shaped clamps 3032. The fan-shaped clamps 3032 are made of spring steel and have a certain elastic deformation capability. There is a gap between each pair of fan-shaped clamps 3032. It should be noted that each of the opposite ends of the horizontal tubes 302 is fixedly connected to a flexible hose connected to an external air pump for evacuating and over-inflating the horizontal tubes 302. When the diameter of the end of the steel roller is larger than the cylindrical groove 3033, The two horizontal tubes 302 can be moved closer together by the movement of the moving platform 102. The columnar body formed by the fan-shaped clamps 3032 can then be used to clamp and position the two ends of the steel rod, making it easier to chamfer the end edge of the steel rod. When the end diameter of the steel rod is smaller than the cylindrical groove 3033, the air pump can be used to extract the gas in the horizontal tube 302, causing the sliding tube 3031 to move towards the inside of the horizontal tube 302 under negative pressure. This will drive the three fan-shaped clamps 3032 towards the conical groove 3024. The edge of the conical groove 3024 will abut against the outer wall of the three fan-shaped clamps 3032, bringing them closer together. This reduces the size of the cylindrical groove 3033, making it easier to wrap and clamp the end of the steel rod on the inner wall. Compared with the abutment clamping method, the contact surface is larger and more stable, which facilitates the chamfering and cutting of the stepped edge of the stepped steel rod, improving the functionality and flexibility of the device.

[0046] like Figures 9-10 As shown, in some embodiments, an annular cavity 3025 is constructed within the inner wall of the horizontal tube 302. One end of the annular cavity 3025 has a flow hole 3026 communicating with the inner bore of the horizontal tube 302. Both the annular cavity 3025 and the flow hole 3026 are internal structures of the horizontal tube 302. Therefore, the horizontal tube 302 can be formed by steel casting or by separate processing followed by welding to ensure internal airtightness. The circumferential side of the slide tube 3031 has multiple air inlets 30311 and exhaust holes 30312 communicating with the flow hole 3026. A one-way valve 5 is installed inside the port of the slide tube 3031. The one-way valve 5 includes a sealing ball disposed within the opening of the slide tube 3031. The sealing ball is positioned between the sealing ball and the inner end of the slide tube 3031. Connected to a support spring, the slide tube 3031 has two forms: one where it moves toward the interior of the horizontal tube 302 and stops, in which case the exhaust port 30312 on the slide tube 3031 is connected to the flow port 3026; and the other where it moves toward the exterior of the horizontal tube 302 and stops, in which case the air inlet port 3031 on the slide tube 3031 is connected to the flow port 3026. The slide tube 3031 has a spacer inside. The exhaust port 30312 is located on the side of the spacer facing the fan-shaped clamp 3032, while the air inlet port 30311 is located on the side of the spacer facing the interior of the horizontal tube 302. The pneumatic support 304 includes multiple T-shaped support plates 3041 slidably inserted into the outer wall of the horizontal tube 302. The T-shaped support plates 3041 are arranged in a circumferential array and face... A rubber plunger 3042 is fixedly connected to one end of the horizontal tube 302. The rubber plunger 3042 is connected to the end of the T-shaped support plate 3041 and is used as a piston. Multiple movable grooves 3027 for wrapping the rubber plunger 3042 are constructed on the inner wall of the annular cavity 3025. An elastic sealing piece 3043 is fixedly connected to the edge of the movable groove 3027 at the end of the rubber plunger 3042. When an external air pump evacuates the horizontal tube 302, the one-way air valve 5 seals the opening of the slide tube 3031, thereby using negative pressure to move the slide tube 3031 towards the interior of the horizontal tube 302, so that the fan-shaped clamping blocks 3032 can approach each other and wrap and clamp the steel rod. When the external air pump blows air into the horizontal tube 302, it can utilize… The high-pressure contact one-way air valve 5 opens and drives the slide tube 3031 to move a certain distance toward the outside of the horizontal tube 302 before stopping. At this time, the air inlet 30311 on the slide tube 3031 will connect with the flow hole 3026, thereby using high air pressure to push the rubber plunger 3042 toward the outside of the horizontal tube 302, so that the T-shaped support plate 3041 can be used to contact and support the inner wall of the tubular steel rod, which is convenient for clamping and positioning operations. The elastic sealing plate 3043 is made of rubber, and its elastic deformation can expand with the movement of the rubber plunger 3042. When the gas supply is stopped and the gas is released through the exhaust hole 30312, the elastic sealing plate 3043 will use its own elasticity to pull the rubber plunger 3042 back to its original position, improving convenience.

[0047] like Figures 9-10 As shown, in some embodiments, the outer wall of the slide tube 3031 is circumferentially arrayed with multiple strip grooves 30313, and the inner wall of the horizontal tube 302 is fixedly connected with multiple guide positioning blocks 3028 that are slidably inserted into the strip grooves 30313. The strip grooves 30313 and the guide positioning blocks 3028 slidably installed therein can guide the sliding of the slide tube 3031 on the one hand, and limit the moving distance of the slide tube 3031 on the other hand, so that the air inlet 30311 and the exhaust 30312 can be accurately connected to the flow hole 3026.

[0048] like Figure 11 As shown, in some embodiments, the feeding mechanism 4 includes a mounting base 401 fixedly connected to the frame 1, a movable block 402 slidably mounted on the mounting base 401, and a cylinder push rod 403 with its output end connected to the mounting base 401. An inclined material holding rack 404, covering the mounting base 401, is fixedly connected to the frame 1. L-shaped grooves 405 are constructed on both sides of the inclined material holding rack 404. A chain plate 406, hinged to the movable block 402 and slidably mounted within the L-shaped grooves 405, is connected to the other end of the chain plate 406. Two Y-shaped lifting rods 407 are fixedly connected to the other end of the chain plate 406. The material is fed by the cylinder push rod 403. The push mechanism can move the chain plate 406 along the L-shaped slide 405. When the chain plate 406 enters the vertical section of the L-shaped slide 405, the Y-shaped lifting rod 407 is set vertically upward to lift the steel rod at the end of the inclined material rack 404, so that it can be gradually lifted between the two horizontal tubes 302 for easy clamping. Conversely, when the cylinder push rod 403 pulls the chain plate 406, the Y-shaped lifting rod 407 can be gradually restored to the horizontal state along the L-shaped slide 405 without affecting the subsequent sliding of the steel rod, ensuring the normal operation of the equipment, and automating the feeding and clamping, thus improving the convenience of the device.
