Description

Technical Field

[0001] This invention relates to the field of thickness gauge purging device technology, and particularly to a thickness gauge purging device. Background Technology

[0002] In existing technologies, thickness gauges used in hot rolling applications are typically installed at the F7 exit of the finishing mill. By accurately measuring the strip thickness at the finishing mill exit, the center thickness measurement data is sent to the primary PLC system and the secondary system to establish a strip shape data model. This model forms a closed-loop feedback control of the convexity with the strip shape control system. However, because the thickness gauge is located at the F7 exit, close to the water spray on the exit side, and due to external interference, a large amount of water vapor and mist can form above the thickness gauge's ray holes. Furthermore, it is difficult to prevent foreign objects, dirt, and dust from falling onto the ray shield, leading to inaccurate center thickness measurements. This causes the secondary model to automatically adjust the thickness, ultimately resulting in discrepancies in the thickness of strips in batches, causing incalculable consequences. To mitigate economic losses, some thickness gauges are equipped with purging devices. For example, a utility model with authorization announcement number CN214407402U discloses a water and mist removal device for a hot-rolled strip thickness gauge and width gauge. By designing the main guide groove as a grid beam structure and adding a purging device, residual water and mist are effectively removed, completely solving the problem of inaccurate measurement data caused by residual water and mist at the measurement position. This ensures the functionality of the measuring equipment and product quality. However, simply using air to clean the surface of the X-ray window is insufficient to guarantee thorough cleaning. Some foreign objects and dirt attached to the X-ray shielding plate are difficult to clean, affecting the final measurement data. Summary of the Invention

The first engaging mechanism is configured to drive the wrist to rotate around a first direction under the drive of the first drive mechanism. A first transmission mechanism is provided on the other side of the wrist, and a second drive mechanism is connected to the first transmission mechanism to drive the first transmission mechanism to move. A connecting portion is provided at the end of the wrist away from the forearm, and the connecting portion is connected to the first transmission mechanism.

[0024] It should be noted that this invention achieves multi-angle movement of the working tool by setting a first drive mechanism and a second drive mechanism on the forearm and placing the connecting part for connecting the working part on the wrist. The first drive mechanism controls the movement of the wrist relative to the forearm, and the second drive mechanism controls the movement of the connecting part relative to the wrist. Furthermore, placing the first transmission mechanism on the wrist further simplifies the transmission and wrist structures, reducing the size of the robotic arm and enabling it to simultaneously possess both a compact structure and multi-angle movement capabilities.

[0029] Optionally, a synchronous pulley is provided on the output shaft of the first drive motor, and a synchronous pulley is provided on the input shaft of the harmonic reducer. The synchronous pulleys on the first drive motor and the harmonic reducer achieve belt drive through a synchronous belt, thereby transmitting the power from the first drive motor to the harmonic reducer, and then from the harmonic reducer to the first mating mechanism.

[0030] In some embodiments, the first drive motor and harmonic reducer can also be driven by various transmission methods such as gear transmission and chain transmission. Those skilled in the art can adjust the transmission method according to the actual use and environment.

[0031] Based on the above technical solution, further embodiments that can be adopted by those skilled in the art include a first mating mechanism comprising multiple screw holes provided on the wrist and multiple screws connecting the output shaft of the harmonic reducer to the wrist.

[0032] Optionally, the wrist part is provided with multiple screw mounting holes, and the output shaft of the harmonic reducer is provided with multiple screw holes for screws to pass through. Multiple screws pass through the screw holes on the output shaft of the harmonic reducer and connect with the screw mounting holes on the wrist part, thereby realizing the connection between the harmonic reducer and the wrist part.

[0033] In some embodiments, the first mating mechanism can be a mating hole that engages with the output shaft of the harmonic reducer. A key is provided on the output shaft of the harmonic reducer, and a keyway is provided inside the mating hole. The output shaft and the mating hole are connected by the key, thereby realizing the connection between the output shaft of the harmonic reducer and the mating hole.

[0034] Based on the above technical solution, further implementation methods that can be adopted by those skilled in the art include: the second drive mechanism includes a second drive motor and an auxiliary drive component, wherein the second drive motor is disposed on one side of the forearm and located at the end of the forearm away from the wrist.

[0035] The auxiliary drive component is connected to the second drive motor and to the first transmission mechanism. The second drive motor drives the auxiliary drive component to rotate, and the auxiliary drive component drives the first transmission mechanism to move.

[0036] Optionally, the second drive motor is arranged opposite to the first drive motor, that is, the second drive motor and the first drive motor are arranged opposite to each other within the mounting space formed by the forearm housing and the forearm side plate. The second drive motor is fixed to the inside of the forearm housing by a motor mounting plate.

[0037] Optionally, the auxiliary driving component is a first bevel gear that is connected to the second drive motor.

[0038] Optionally, a synchronous pulley is provided on the output shaft of the second drive motor, and a synchronous pulley is connected to the first bevel gear. The synchronous pulley on the first bevel gear and the synchronous pulley on the second drive motor are connected by a synchronous belt drive.

[0039] Optionally, a bushing supporting the first bevel gear is provided on the forearm to ensure that the first bevel gear can rotate under the drive of the second drive motor.

[0040] Based on the above technical solution, the following implementation methods can be further adopted by those skilled in the art: the first transmission mechanism includes an axial member, a first transmission member and a second transmission member, the first transmission member is disposed at one end of the axial member, the first transmission member is connected to the auxiliary drive member, and the first transmission member is configured to drive the axial member to rotate under the drive of the auxiliary drive member.

[0041] The second transmission member is located at the other end of the axial member. The second transmission member is configured to rotate with the axial member. The second transmission member is connected to the connecting part in a transmission manner so that the connecting part rotates under the drive of the auxiliary drive member.

[0042] It should be noted that the wrist area has an internal space for installing the first transmission mechanism.

[0043] Optionally, the first transmission component is a second bevel gear that meshes with the first bevel gear. The second transmission component is a shaft gear, and the connecting part is provided with a gear structure that meshes with the shaft gear.

[0044] In some embodiments, the first transmission member and the axial member are detachably connected. The second transmission member and the axial member are also detachably connected.

[0045] Optionally, the axial member has an external gear assembly at the end connected to the second bevel gear. A shaft-shaped gear is located on the upper part of the second bevel gear. The external gear assembly connects to the shaft-shaped gear portion of the second bevel gear. A screw is provided at one end of the axial member, fixing the external gear assembly to the axial member so that the first bevel gear transmits power to the axial member through the second bevel gear, causing the axial member to rotate, thereby driving the shaft gear to rotate.

[0046] In some embodiments, the external gear assembly includes a bushing that meshes with the shaft-shaped gear of the second bevel gear. The bushing has a cavity and a pin hole on its gear plate surface for inserting a flat pin and a spring. The bushing's gear plate has a pin hole for inserting the pin. After the pin and bushing are fitted together, under the action of the spring's elastic force, the bushing and gear plate generate a rotational torque in the radial direction, thereby eliminating backlash when both simultaneously mesh with the shaft-shaped gear portion of the second bevel gear.

[0047] In some embodiments, the bushing gear disc surface is provided with a hole and external threads for mating with the bushing. The gear disc has a slotted hole to allow for a clearance fit between the gear disc and the bushing, while preserving an appropriate radial clearance reduction. After inserting the pin, radial movement between the bushing and the gear disc is achieved, thereby eliminating the clearance during meshing with the shaft gear.

[0048] A cross bearing is fitted on the outer side of the bushing. The outer diameter of the cross bearing fits into the inner cavity of the wrist housing to support the entire external gear assembly.

[0049] In some embodiments, a first bearing is provided outside the external gear assembly to ensure that the first transmission mechanism can rotate within the mounting space of the wrist. A spline sleeve is provided between the external gear assembly and the first bearing, and a retaining ring is provided on the spline sleeve to prevent cross-movement between the bearing and the spline sleeve.

[0050] In some embodiments, a helical compression spring is provided between the spline sleeve and the second bevel gear to eliminate the meshing gap with the first bevel gear by utilizing the axial preload of the second bevel gear.

[0051] In some embodiments, to prevent the second bevel gear from skipping due to sudden changes in transmitted torque between the first and second bevel gears, a retaining ring groove is designed on the outer circle of the second bevel gear, and a retaining ring is provided to control the retraction stroke of the second bevel gear.

[0052] In some embodiments, a spline groove is provided in the inner hole of the spline sleeve, and a matching spline groove is designed on the outer circle of the second bevel gear.

[0053] In some embodiments, an output flange is provided on the output side of the bushing. A cross-bearing is press-fitted into the bushing via a fit and screw connection to prevent axial movement between them. A mounting hole for direct tool connection is provided at the output end of the output flange for tool mounting.

[0054] In some embodiments, the axial component, the first bevel gear, and the shaft gear are integrated into a single structure.

[0055] In some embodiments, a pin bearing is mounted on an axial member above the shaft gear to support the shaft gear. The pin bearing is mounted above the shaft gear to ensure that the shaft gear can rotate within the mounting space of the wrist.

[0056] Specifically, a bearing retainer is provided between the nail roller bearing and the axial component to prevent the nail roller bearing from moving along the axial component.

[0057] Based on the above technical solution, the following implementation methods can be further adopted by those skilled in the art: the end of the forearm connected to the wrist has a first extension arm and a second extension arm that are arranged opposite to each other, there is a preset distance between the first extension arm and the second extension arm, one side of the wrist is connected to the first extension arm, and the other side of the wrist is connected to the second extension arm.

[0058] The first drive mechanism is arranged along the first extension arm, and the second drive mechanism is arranged along the second extension arm.

[0059] Understandably, by forming a hollow section at one end of the forearm through the first and second extension arms, space is provided for wrist rotation, facilitating wrist rotation and further saving the size of the robotic arm.

[0060] Based on the above technical solution, further implementation methods that can be adopted by those skilled in the art include having the first direction and the second direction perpendicular to each other.

[0061] Specifically, the axis of the first bevel gear is perpendicular to the axis of the second bevel gear, and the axis of the connecting part is parallel to the axis of the second bevel gear.

[0062] The present invention also provides a robot, including the aforementioned robotic arm. Since this robot possesses some or all of the technical effects of the aforementioned robotic arm embodiments, they will not be described in detail here. Figure 1-3 As shown, the present invention is a thickness gauge purging device, including a C-shaped frame 1, a strip steel 2 is arranged between the upper and lower support arms of the C-shaped frame 1, the strip steel 2 runs on the conveyor roller table in the hot rolling production line (the conveyor roller table is not shown in the figure), the strip steel 2 passes through the C-shaped frame 1 in the driving direction of the conveyor roller table, and the thickness gauge on the C-shaped frame 1 is used to detect the strip steel 2.

[0063] The upper and lower arms of the C-frame 1 are respectively provided with a radiation exit chamber 3 and a detection ionization chamber 4 on their sides that are close to each other. The radiation exit chamber 3 and the detection ionization chamber 4 are arranged correspondingly. A protective plate 5 is provided at the upper end of the radiation exit chamber 3. The C-frame 1 has an accommodating space, namely the radiation exit chamber 3. The radiation emitter is fixed in the radiation exit chamber 3. The C-frame 1 provides sealed protection for the radiation emitter. Several detection holes are opened on the upper arm of the C-frame 1 corresponding to the position of the radiation hole. As a preferred structure, the several detection ionization chambers 4 are arranged in a ring to improve space utilization.

[0064] The protective plate 5 is a metal plate, which protects the radiation outlet.

[0065] A fixed frame 6 is connected to one side of the upper end of the C-frame 1. A nozzle 7 is installed on the side of the fixed frame 6 near the X-ray exit chamber 3. The nozzle 7 is connected to a gas source component 9 through a gas guide pipe 8. The fixed frame 6 is connected to the lower wall fixed plate of the C-frame 1 by fasteners, such as bolts and nuts. The gas guide pipe 8 is connected to the nozzle 7. The gas source component 9 can be an air compressor or similar structure, which can blow air through the gas guide pipe 8 and out through the nozzle 7. The gas blown out from the nozzle 7 can purge the water vapor below the strip 2 and the upper surface of the protective plate 5, blowing away the water vapor, mist, and some impurities on the protective plate 5, ensuring the cleanliness of the protective plate 5, and thus improving the accuracy of the thickness gauge measurement data. The pressure of the purging gas is 5-10 bar, which is sufficient to ensure that the purging gas cleans the water vapor, dust, and other foreign matter on the upper surface of the protective plate 5.

[0066] The air guide pipe 8 is a flexible hose. The flexible hose is beneficial for the layout of the equipment in the hot rolling production line and improves flexibility.

[0067] A pressure stabilizing tank 10 is connected between the gas source component 9 and the nozzle 7. The pressure stabilizing tank 10 ensures the stability of the purging gas pressure. A manual valve is installed on the air guide pipe 8 between the pressure stabilizing tank 10 and the gas source component 9. The manual valve controls the delivery or cut-off of the purging gas in the gas source component 9.

[0068] There are two sets of nozzles 7. One set of nozzles 7 is set parallel to the protective plate 5, and the other set of nozzles 7 is set tilted downwards. The nozzles 7 parallel to the protective plate 5 can blow away the water vapor below the strip steel 2, and the nozzles 7 tilted downwards can blow the gas to the upper surface of the protective plate 5 to sweep away the mist and some debris.

[0069] A fixed base 11 is connected to the side of the C-shaped frame 1. A rotating shaft 12 is movably connected to the fixed base 11. A motor 13 is connected to the rotating shaft 12. The motor 13 is connected to an external power supply and a control switch. The rotating shaft 12 can be driven to rotate through the motor 13.

[0070] A rotating rod 14 is fixedly connected to the rotating shaft 12, and a wiping component 15 is movably connected to the bottom end of the rotating rod 14, such as... Figure 2 As shown, when the rotating shaft 12 rotates, it can drive the rotating rod 14 to rotate. The length of the rotating rod 14 is at least enough to cover the protective plate 5. The wiping component 15 can be a wiping cloth or other wiping component. When the rotating rod 14 rotates under the drive of the rotating shaft 12, the wiping component 15 passes over the upper surface of the protective plate 5 and wipes the upper surface of the protective plate 5 to sweep off and remove dirt or foreign objects attached to the protective plate 5. The water vapor brought to the protective plate 5 by the wiping component 15 can be dried by the gas sprayed from the nozzle 7. The connection between the wiping component 15 and the rotating rod 14 is detachable, which makes it easy to disassemble, replace or clean the wiping component 15.

[0071] The bottom end of the rotating rod 14 is provided with a hook and loop fastener female surface 16, and the top end of the wiping component 15 is provided with a hook and loop fastener female surface 17. The hook and loop fastener female surface 16 and the hook and loop fastener female surface 17 are configured to cooperate. By utilizing the cooperation between the hook and loop fastener female surface 16 and the hook and loop fastener female surface 17, a detachable connection can be achieved between the wiping component 15 and the bottom of the rotating rod 14, which is convenient for installation and disassembly.

[0072] A cleaning water tank 18 and a hot air box 23 are respectively installed on the fixed base 11. A cleaning brush 22 is connected to the cleaning water tank 18 via a linear drive 21. When the rotating rod 14 rotates above the cleaning water tank 18, the linear drive 21 drives the cleaning brush 22 to reciprocate at the bottom of the rotating rod 14, cleaning the wiping component 15. Simultaneously, the cleaning liquid in the cleaning water tank 18 works in conjunction with the cleaning brush 22 to clean the wiping component 15, improving the thoroughness of cleaning. After cleaning, the liquid in the cleaning water tank 18 can be drained, allowing the water on the wiping component 15 to drip back into the cleaning water tank 18. Then, the rotating rod 14 is used again to move the wiping component 15 above the hot air box 23, where the hot air box 23 dries the wiping component 15 for future use, improving the automation of cleaning and facilitating future use. When in use, the dried wiping piece 15 can be used directly to clean the upper surface of the protective plate 5, or the wiping piece 15 can be soaked in the cleaning water tank 18 first to clean the surface of the protective plate 5. The choice can be made according to the usage needs. The motor 13 can be a forward and reverse geared motor. When the dried wiping piece 15 is used to clean the upper surface of the protective plate 5, the rotating rod 14 placed on the hot air box 23 is rotated directly towards the protective plate 5 without passing through the cleaning water tank 18 side to achieve the cleaning of the protective plate 5 by the dried wiping piece 15. When the wet wiping piece 15 is used to clean the protective plate 5, clean water is first poured into the cleaning water tank 18, the wiping piece 15 is rotated to the top of the cleaning water tank 18 to soak the wiping piece 15 in clean water, and then the wiping piece 15 is rotated onto the protective plate 5 for cleaning. The specific cleaning method can be selected according to the usage needs.

[0073] The cleaning tank 18 is connected to an inlet pipe 19 and a drain pipe 20 on its side. The inlet pipe 19 and the drain pipe 20 are connected to a water storage tank and a liquid pump, which can be used to fill or drain water from the cleaning tank 18.

[0074] The linear drive component 21 includes a lead screw 211 and a lead screw nut 212. The lead screw 211 is movably connected inside the cleaning water tank 18. The lead screw 211 is connected to a drive component. The lead screw nut 212 is threaded onto the lead screw 211. The upper end of the lead screw nut 212 is connected to the cleaning brush 22. The lead screw 211 can be externally connected to a drive component such as a motor, which can drive the lead screw 211.

[0075] The above description is merely an optional embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made using the contents of the present invention's specification and drawings under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present invention.
