Description

Technical Field

[0001] This invention relates to the field of torque detection technology, and more particularly to a torque detection device for a rotating rod in tool processing equipment. Background Technology

[0002] When assembling a hand tool with a protective rotating rod, it is necessary to meet two requirements: the rotating rod can be manually driven to rotate around the rotating axis, and the rotating axis can be stably stopped at the target rotation angle by means of the clamping component after the hand is released. Therefore, the force required to drive the rotating rod to rotate must be accurately detected by a torque detection device. The existing solution includes a detection device with a pressure sensor and a thrust gauge, and a drive device for driving the detection device. First, the dimensions of the rotating shaft body need to be obtained in advance. Then, the pressure sensor is driven to contact the rotating shaft body through the drive device. Based on these dimensions, the height position of the detection device needs to be adjusted by the drive device to align the rotation center of the thrust gauge with the center of the rotating shaft for subsequent detection work. This results in a cumbersome process for detecting the torque of the rotating rod.

[0003] Therefore, a new rotating rod torque detection device is needed to solve the problem of cumbersome rotating rod torque detection procedures. Summary of the Invention

[0004] The purpose of this application is to provide a new rotating rod torque detection device that can solve the problem of cumbersome rotating rod torque detection procedures.

[0005] To achieve the above objectives, the embodiments of this application adopt the following technical solution: a torque detection device for a rotating rod of a tool processing equipment, comprising: a base, on which a slide rail and a guide assembly are provided; a sliding assembly, which is slidably disposed on the slide rail; a lifting assembly, which is fixedly disposed on the sliding assembly; a connecting shaft, which is fixedly disposed on the lifting assembly, and one end of the connecting shaft is provided with a driving device; a centering assembly, which is slidably disposed on the guide assembly, and the centering assembly is provided with a guide portion and a positioning cavity, wherein the positioning cavity is provided with a plurality of arc-shaped steps with different outer diameters, the arc-shaped steps being used to abut the edge of the rotating rod of the workpiece to be tested, the lifting assembly being used to drive the connecting shaft, so that the connecting shaft is aligned with the guide portion to determine the rotation center of the rotating rod; and a thrust gauge, which is mounted on the connecting shaft, the sliding assembly being used to drive the connecting shaft, so that the thrust gauge moves to the rotation path of the rotating rod, and the driving device being used to drive the connecting shaft, thereby driving the thrust gauge, so that the thrust gauge pushes the rotating rod to perform torque detection.

[0006] Furthermore, the guide assembly includes two sliding plates slidably disposed on the base; Furthermore, the sliding component includes a frame fixedly mounted on the base, an opening at the right end of the frame, a limit frame on the opening, and a sliding groove inside the limit frame. Furthermore, rack 1 is symmetrically arranged inside frame 1, and limit blocks are also arranged inside frame 1; Furthermore, the sliding component includes a second frame that is slidably disposed on the first frame, and four crossbars are provided on both sides of the second frame, which are symmetrically disposed on both sides of the limiting block. Furthermore, a receiving part is provided at the right end of frame two, and a receiving groove is provided on the receiving part. A gear is provided in the receiving groove, and the gear meshes with a rack. Furthermore, a horizontal plate is provided on the outer side of the second frame, and a buffer assembly is provided on the horizontal plate. The buffer assembly includes an eccentric wheel and a buffer tank. An eccentric shaft is fixedly provided on one side of the eccentric wheel. The eccentric shaft is connected to a gear. An eccentric groove is provided on the outer wall of the eccentric wheel. A buffer rod is provided on the buffer tank, and the buffer rod faces the eccentric groove. Furthermore, the sliding component also includes a frame three that is slidably disposed on the frame two, and a rack two is disposed on the frame three, which is meshed with a gear. Furthermore, the lifting assembly is fixedly installed on frame two, located at one edge of the frame. The lifting assembly includes a support frame fixedly installed on frame two, a connecting frame installed on the support frame, a drive shaft installed inside the connecting frame, a bearing seat installed on the rotating shaft, a connecting plate installed on the bearing seat, sliders installed at both ends of the connecting plate, the sliders being slidably installed on the connecting frame, and a handwheel installed at the end of the drive shaft. Furthermore, a sliding frame is provided on the connecting plate, and a connecting shaft is fixedly provided on the bottom of the sliding frame. A rotating part is provided at one end of the connecting shaft, and the rotating part is arranged crosswise with the connecting shaft. A centering hole is provided on the rotating part, and a chassis is provided at the end of the rotating part. A thrust gauge is provided at the edge of the chassis, and a drive motor is provided at the other end of the connecting shaft.

[0007] After obtaining the arc dimension of the end of the rotating rod in advance, the sliding component with the positioning cavity is driven to slide. The positioning cavity is equipped with several arc-shaped steps with different outer diameters. After obtaining the outer diameter dimension of the end of the rotating rod in advance, the sliding component is driven to slide so that the arc-shaped steps of the corresponding size in the positioning cavity abut against the edge of the rotating rod to determine the rotation axis of the rotating rod. Then, the axis of the connecting shaft is adjusted once by the lifting component to align it with the guide part. The thrust gauge can then be driven directly by the sliding component to move onto the rotation path of the rotating rod to detect the torque of the rotating rod, thus solving the problem of the cumbersome steps in detecting the torque of the rotating rod.

It should be understood that the specific embodiments described herein are only some, not all, embodiments of the present invention, and are merely illustrative of the embodiments of the present invention. They are not intended to limit the embodiments of the present invention. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

They are used only for the convenience of describing the invention and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the invention. Furthermore, the terms "a," "first," "second," "third," "fourth," "fifth," and "sixth" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0019] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0020] For purposes of simplicity and illustration, the principles of the embodiments are described primarily by way of example. In the following description, numerous specific details are set forth to provide a thorough understanding of the embodiments. However, it will be apparent to those skilled in the art that these embodiments may not be limited to these specific details in practice. In some instances, well-known methods and structures have not been described in detail to avoid unnecessarily obscuring these embodiments. Furthermore, all embodiments can be used in combination with each other.

[0021] like Figures 1 to 6This embodiment provides a torque detection device for a rotary rod in a tool processing equipment, such as in milling, where a worker cranks a handwheel, which drives a gear-driven rack, and the rack pushes the tool blank in the cutting direction. Later, to reduce the worker's workload and improve efficiency, a servo motor was used to drive the gear-driven rack. However, ordinary servo motors are controlled by PID controllers, and stoppages can cause back-and-forth oscillations leading to insufficient machining. Furthermore, for aesthetic reasons and to prevent excessively long, cantilevered shafts from deforming, or to prevent accidental contact with the shaft causing safety issues, the exposed shaft of the rotating rod 801 used for gripping in molds and most protective rotating rods 801 is generally designed to be relatively short. For example, several different specifications of hand-cranked gear 8 assemblies, including a bracket, rotating rod 801, gear 2021, and rack, are used to manually crank the rotating rod 801 to drive the gear 2021 to rotate. The gear 2021 then rotates the rack, moving the output end of the rack to a predetermined position. The bracket and rotating rod 801 are connected by a clamping assembly to prevent the rotating rod 801 from rotating due to its own weight and causing the rack to run erratically. However, if the clamping assembly provides insufficient clamping... Excessive force may prevent the rotating rod 801 from rotating. Insufficient clamping force from the clamping assembly will also prevent the rotating rod 801 from being clamped. Existing detection devices, such as those with a drive unit, thrust gauge, and pressure sensor, require obtaining the shaft dimensions or the arc dimension of the top edge of the rotating rod. Then, the pressure sensor is moved horizontally above the rotating rod. When the pressure sensor is lowered to contact the rotating shaft, the height of the detection device needs to be adjusted based on these dimensions using the drive unit to align the thrust gauge's rotation center with the rotating shaft's axis for subsequent detection. This process is cumbersome and prone to positioning errors due to the left-right position of the rotating rod's rotation center. A detection device that can solve these problems includes… Example

[0022] like Figures 1 to 6As shown, in this embodiment, the device capable of solving the above problems includes: a base 1, on which a slide rail guide assembly 5 is provided; a sliding assembly 2, which is slidably disposed on the slide rail; a lifting assembly 3, which is fixedly disposed on the sliding assembly 2; a connecting shaft 4, which is fixedly disposed on the lifting assembly 3, one end of which is provided with a driving device, and the other end of which is provided with a centering hole 403; and a centering assembly 6, which is slidably disposed on the guide assembly 5, and which is provided with a guide portion 603 and a positioning cavity 604. The device is equipped with several arc-shaped steps 6041 with different outer diameters. The arc-shaped steps 6041 are used to abut the edge of the rotating rod of the workpiece to be tested. The lifting assembly 3 can drive the connecting shaft 4 to align the centering hole 403 with the guide part 603 to determine the rotation center of the rotating rod 801. The thrust gauge 404 is mounted on the connecting shaft 4. The sliding assembly 2 drives the thrust gauge 404 to move to the rotation path of the rotating rod 801 of the workpiece to be tested. The driving device is used to drive the connecting shaft 4, thereby driving the thrust gauge 404, so that the thrust gauge 404 pushes the rotating rod 801 to perform torque detection.

[0023] By setting guide components 5 to adapt to the outer diameter of the shaft of the rotating rod 801 from both sides, and by setting the corresponding size of the arc-shaped step of the positioning cavity 604 to abut the top edge of the Z-shaped rotating rod 80 of the hand crank gear 8, and by setting sliding components 2 and lifting components 3 to adjust the position of the connecting shaft 4, the rotation center of the rotating rod 801 can be quickly found. Thus, the connecting shaft 4 can be driven by the drive device, the connecting shaft 4 can drive the thrust gauge 404, and the thrust gauge 404 can push the rotating rod 801 to rotate, outputting torque data in real time. This achieves simple operation and solves the problem of deviation caused by the instability of the fixed left and right position when detecting the manual torque of the rotating rod 801 in the hand tool.

[0024] Specifically, the guide assembly 5 includes two sliding plates slidably disposed on the base 1. A sliding seat is provided at the bottom of the sliding plate, and the sliding seat is fixedly disposed on the base 1, thereby realizing that the sliding plate is slidably disposed on the base 1 and enabling the sliding plate to perform opening and closing movements to adapt to the outer diameter of the shaft of the rotating rod 801. The two sliding plates are fixed in corresponding positions by locking screws to limit the left and right positions of the shaft of the rotating rod. A gap is formed between the two sliding plates to provide sliding space for the centering assembly 6 and facilitate the positioning and fixing of the hand crank gear.

[0025] Specifically, the sliding component 2 includes a frame 201 fixedly mounted on the base 1. The right end of the frame 201 has an opening, and a limiting frame 2011 is provided on the opening. A sliding groove is provided inside the limiting frame 2011. A boss is fixedly mounted on the base 1, and the frame 201 is fixedly mounted on the boss, so that the right end of the frame 201 is away from the upper surface of the base 1. The frame 201 is used to support other components of the sliding component 2 and the lifting component 3. Specifically, a rack 2012 is symmetrically arranged inside the frame 201, and a limit block 2013 is also provided inside the frame 201. The sliding component 2 includes a frame 202 slidably arranged on the frame 201. A crossbar 2022 is provided on both sides of the frame 202. There are four crossbars 2022. The crossbars 2022 are symmetrically arranged on both sides of the limit block 2013. The left and right positions of the limit block 2013 are restricted by two crossbars 2022 respectively, thereby guiding the sliding direction of the frame 202. Preferably, the limit block 2013 is a T-shaped block, which further increases the stability of the movement of the frame 202. Specifically, a receiving part is provided at the right end of frame 202, and a receiving groove is provided on the receiving part. A gear 2021 is provided in the receiving groove. The gear 2021 is meshed with rack 1 2012, so that when frame 202 moves along the direction of crossbar 2022, frame 202 is driven to drive the connecting shaft 4 to move laterally. The meshing of gear 2021 with rack 1 2012 drives gear 2021 to rotate. Specifically, a horizontal plate 2023 is provided on the outer side of frame 202, and a buffer assembly 7 is provided on the horizontal plate 2023. The buffer assembly 7 includes an eccentric wheel 702 and a buffer tank 701. An eccentric shaft is fixedly provided on one side of the eccentric wheel 702, and the eccentric shaft is connected to a gear 2021. An eccentric groove 703 is provided on the outer wall of the eccentric wheel 702. A buffer rod 704 is provided on the buffer tank 701, and the buffer rod 704 faces the eccentric groove 703. When frame 202 moves along the direction of the horizontal bar 2022, it will drive the gear 2021 to rotate, and at the same time drive the eccentric shaft to rotate. The eccentric wheel 702 rotates, and the center of the eccentric groove 703 is offset from the center of the eccentric shaft. This continuously presses down the buffer rod 704, causing the buffer rod 704 to move in a piston-like motion with the buffer cylinder. This allows the viscous fluid pre-filled in the buffer cylinder to slow down the speed of the piston movement, thereby absorbing the impact of the movement and preventing rigid movement from damaging the gear 2021 rack and centering assembly 6. Furthermore, the predetermined force based on the buffer cylinder reduces the positional error caused by the gear 2021 rack clearance, thereby further increasing the stability of the movement and increasing the stability of the connection between the guide part 603 and the centering hole 403. Specifically, the sliding component 2 also includes a frame 3 203 slidably disposed on the frame 2 202. The frame 3 203 is used to support the lifting component 3 and the connecting shaft 4. The frame 3 203 is provided with a rack 2 2031, which meshes with the gear 2021. The frame 3 203 has openings at both ends. There are four racks, which are symmetrically disposed at the upper and lower ends of the frame 3 203. The frame 3 203 is also provided with a strip-shaped sliding part 2032 corresponding to the direction of the racks. The frame 1 201 is provided with a corresponding sliding groove. The frame 2 202 can be driven to move within the frame 1 201, thereby driving the gear 2021 to rotate, so as to drive the frame 3 203 to move synchronously in the opposite direction, thereby realizing the sliding movement of the frame 3 203 to adjust the left and right position of the connecting shaft 4. Specifically, the lifting assembly 3 is fixedly installed on frame two 202, located at the end edge of frame one 201. The lifting assembly 3 includes a support frame 301 fixedly installed on frame two 202, a connecting frame 302 installed on the support frame 301, a drive shaft installed inside the connecting frame 302, a bearing seat installed on the rotating shaft, a connecting plate installed on the bearing seat, sliders 305 installed at both ends of the connecting plate, the sliders 305 slidingly installed on the connecting frame 302, and a handwheel installed at the end of the drive shaft. The connecting frame 302 has a top plate and a bottom plate at its upper and lower ends, respectively. A guide post is installed on the bottom plate, the sliders 305 slidingly installed on the guide post, and the handwheel is installed on the top plate. By rotating the handwheel, the drive shaft is rotated, which causes the rotating drive shaft to move the bearing seat up and down. The bearing seat drives the connecting plate, and the connecting plate drives the sliders 305, which slide along the guide post to guide the movement of the connecting plate.

[0026] Specifically, a sliding frame 303 is provided on the connecting plate, and a connecting shaft 4 is fixedly provided on the bottom of the sliding frame 303. A rotating part 402 is provided at one end of the connecting shaft 4. The rotating part 402 is arranged crosswise with the connecting shaft 4. A centering hole 403 is provided on the rotating part 402. A chassis is provided at the end of the rotating part 402. A thrust gauge 404 is provided at the edge of the chassis, so that the thrust gauge 404 can be driven by the moving component. The rotating rod 801 of the test piece is located on the movement path of the thrust gauge 404. A drive motor 401 is provided at the other end of the connecting shaft 4. The drive motor 401 is used to drive the connecting shaft 4 to rotate, thereby driving the thrust gauge 404 to rotate and push the rotating rod 801 to output a value.

[0027] Specifically, in order to limit the extreme movement position of frame two 202 and prevent the right push from causing the rack of gear 2021 to disengage, frame four 204 is fitted on the right end of frame one 201. The two sides of frame four 204 are provided with strip grooves, and the position of the strip grooves corresponds to the position of eccentric wheel 702.

[0028] Specifically, the centering component 6 is provided with a guide part 603 corresponding to the centering motion. The guide part 603 is used to guide the position of the connecting shaft 4 so as to quickly receive and adjust the position of the connecting shaft 4 for centering. This eliminates the need for complex corrections of straight line detection and avoids human error from manual measurement, resulting in more stable data that is closer to the actual manual torque value.

[0029] Specifically, in order to enable the positioning cavity 604 to more flexibly position the rotation center of the rotating rod 801, the centering assembly 6 is provided with a sliding member 601 and a positioning block 602. The sliding member 601 has a sliding groove on both sides, a connecting groove at one end of the sliding member 601, and a limiting groove communicating with the connecting groove at the other end. A guide rod 606 is provided on the connecting groove. One end of the guide rod 606 is fixedly set in the positioning, and the other end of the guide rod 606 is slidably set with a sliding column 6061, which is used to allow the positioning block 602 to be manually pulled out to adjust its position, so that the positioning cavity 604 can abut against the top edge of the vertical rod at the middle position of the rotating rod 801 to achieve centering of the rotation center of the rotating rod 801. Specifically, to facilitate the reset of the guide rod 606, the sliding column 6061 is inclined relative to the axis of the guide rod 606. A spring 6062 is provided between the sliding column 6061 and the guide rod 606. The spring 6062 is used to drive the sliding column 6061 to move outward, thereby driving the guide rod 606 to move inward. The guide rod 606 drives the positioning block 602 to reset the positioning block 602, and the centering accuracy can be further increased by the force of the positioning block 602 moving inward.

[0030] Specifically, in order to limit the guide rod 606, a limiting member 608 is provided in the limiting groove, an end cap 605 is provided at the right end of the sliding member 601, an inclined surface is provided on the limiting member 608, and a protrusion is provided at the other end of the guide rod 606, with a corresponding inclined surface on the protrusion; a limiting sleeve 607 is also provided in the limiting groove, the limiting sleeve 607 is located on the movement path of the protrusion, and is used to limit the extreme movement position of the guide rod 606.
