Technical Field

[0001] This application relates to the field of processing equipment technology, and in particular to a polishing apparatus for irregularly shaped parts. Background Technology

[0002] Irregular parts refer to components whose shape and structure differ significantly from traditional standard parts. Among them, rod or tube parts are particularly important in industrial equipment. In addition to round rods or tubes, there are rods or tubes with other cross-sectional shapes, as well as variable diameter tubes or rods with constantly changing cross-sectional areas.

[0003] When grinding and polishing irregular rods or pipes of the type mentioned above, the surface of irregular parts has curved or inclined surfaces and other irregular structures.

[0028] Example 1 See attached document Figures 1-3 This embodiment provides a polishing apparatus for irregularly shaped parts, comprising: Workbench 1; The polishing mechanism includes an upper grinding roller 2 and a lower grinding roller 3 disposed on a worktable 1. The upper grinding roller 2 and the lower grinding roller 3 can be driven to rotate to polish the outer surface of the part. The lifting mechanism includes two sets of upper lifting platforms 4 and lower lifting platforms 5 that are vertically slidably arranged on the worktable 1. The two ends of the upper grinding roller 2 are arranged on the lifting platform, and the two ends of the lower grinding roller 3 are arranged on the lower lifting platform 5. The upper lifting platform 4 and lower lifting platform 5 can be driven to move vertically to adjust the distance between the upper grinding roller 2 and the lower grinding roller 3. The horizontal adjustment mechanism includes a movable frame disposed on the worktable 1, a lifting mechanism disposed on the movable frame, and the movable frame can be driven to move along the length direction of the part; The distance acquisition unit, set on the movable frame, is used to detect the distance between the bottom of the upper grinding roller 2 and the top of the lower grinding roller 3 and the position of the part to be ground; The control unit is electrically connected to the lifting mechanism, the horizontal adjustment mechanism and the distance acquisition unit. The control unit is used to receive the data collected by the distance acquisition unit in order to adjust the distance between the upper grinding roller 2 and the lower grinding roller 3 according to the collected data.

[0029] The fixing mechanism is set on the base and located on both sides of the polishing mechanism, and is used to clamp and fix the two ends of the parts.

[0030] In this embodiment, the workbench 1 serves as the basic support structure of the entire polishing device. The workbench 1 can be constructed in various forms, such as welded steel structure, cast frame or modular aluminum profile. Its main function is to provide sufficient rigidity and stability to support all components such as polishing mechanism, lifting mechanism, horizontal adjustment mechanism, distance acquisition unit, control unit and fixing mechanism, and to ensure their relative positional accuracy during operation. For example, the workbench 1 can be a frame welded from rectangular steel pipes, with its bottom fixed to the ground and installation interfaces on the top and sides for installing other functional modules.

[0031] The upper grinding roller 2 and the lower grinding roller 3 can be made of various materials such as grinding wheels, polishing wheels or brush rollers to adapt to different polishing needs. The upper grinding roller 2 and the lower grinding roller 3 are driven to rotate by their respective drive devices. For example, each grinding roller can be directly driven by an independent servo motor. By adjusting the speed and direction of the motor, efficient polishing and grinding of the outer surface of the parts can be achieved.

[0032] The two ends of the upper grinding roller 2 are set on the upper lifting platform 4, and the two ends of the lower grinding roller 3 are set on the lower lifting platform 5. The upper lifting platform 4 and the lower lifting platform 5 can be driven to move vertically to adjust the distance between the upper grinding roller 2 and the lower grinding roller 3. For example, the lifting mechanism can adopt a simple screw transmission mechanism, in which a motor drives a screw to rotate, and the nut on the screw is connected to the lifting platform, thereby realizing the vertical movement of the lifting platform.

[0033] The distance acquisition unit can use a variety of non-contact sensors, such as laser rangefinders, ultrasonic sensors, or vision sensors. For example, a single laser rangefinder can be used to acquire the contour data of the part by scanning manually or along a preset path before polishing.

[0034] The control unit is used to receive the data collected by the distance acquisition unit, and adjust the distance between the upper grinding roller 2 and the lower grinding roller 3 according to the collected data. The control unit can be a programmable logic controller (PLC) or an industrial computer. For example, the control unit can preset a simple lookup table, determine the adjustment amount of the grinding roller distance by looking up the table according to the collected distance data, and then send the instruction to the drive device of the lifting mechanism.

[0035] The following is a specific implementation method for polishing an irregularly shaped rod with a complex variable diameter and curved surface structure. Both ends of the rod are fixed by a fixing mechanism, securing the rod between the upper grinding roller 2 and the lower grinding roller 3. The device is activated, causing the upper and lower grinding rollers 2 and 3 to rotate. A horizontal adjustment mechanism drives a moving frame on the moving frame to move along the length of the irregularly shaped rod. During the movement of the moving frame, a distance acquisition unit mounted on the moving frame continuously operates. This distance acquisition unit detects in real-time the distance between the bottom of the upper grinding roller 2 and the top of the lower grinding roller 3 and the position on the irregularly shaped rod to be polished. For example, when the moving frame moves to a variable diameter area of ​​the irregularly shaped rod, the distance acquisition unit detects the diameter change in that area, thereby obtaining real-time distance data between the grinding rollers and the surface of the part.

[0036] The distance data collected by the acquisition unit is transmitted to the control unit in real time. After receiving the data, the control unit analyzes the data according to the preset polishing strategy and algorithm. For example, the control unit calculates the optimal spacing between the upper grinding roller 2 and the lower grinding roller 3 required for the current position based on the detected distance data, so as to ensure that the grinding rollers can polish the surface of the part with appropriate pressure and contact area, while avoiding damage to the part.

[0037] Based on the optimal spacing calculated by the control unit, the control unit sends a command to the lifting mechanism. Upon receiving the command, the lifting mechanism drives the upper lifting platform 4 and the lower lifting platform 5 to move vertically. Since the two ends of the upper grinding roller 2 are set on the upper lifting platform 4 and the two ends of the lower grinding roller 3 are set on the lower lifting platform 5, the movement of the upper lifting platform 4 and the lower lifting platform 5 will precisely adjust the vertical spacing between the upper grinding roller 2 and the lower grinding roller 3. For example, when the diameter of the irregular rod increases, the control unit will command the lifting mechanism to increase the grinding roller spacing; when the diameter decreases, it will command to decrease the grinding roller spacing.

[0038] Throughout the process, the upper grinding roller 2 and the lower grinding roller 3 in the polishing mechanism are continuously driven to rotate. With the horizontal movement of the moving frame and the vertical adjustment of the lifting mechanism, the upper grinding roller 2 and the lower grinding roller 3 always maintain appropriate contact with the surface of the irregular rod, continuously polishing and grinding it. Working together, even when faced with irregular parts with complex curved surfaces and varying diameters, this device can achieve all-round and highly efficient polishing of their outer surfaces.

[0039] As an optional implementation, the leveling mechanism further includes: Two transverse guide rails 7 are set on the worktable 1 and located at both ends of the upper grinding roller 2 and the lower grinding roller 3; Slider 8 is slidably mounted on transverse guide rail 7, and the movable frame is used to connect slider 8 on the two transverse guide rails 7. Guide screw 9 is rotatably mounted on worktable 1, and guide screw 9 is threadedly engaged with slider 8; The first driving component 10 is disposed on the worktable 1 and is used to drive the guide screw 9 to rotate so that the slider 8 moves along the transverse guide rail 7.

[0040] In this embodiment, the two transverse guide rails 7 can be linear rolling guide rails, such as linear guide rail pairs using balls or rollers as rolling elements, which can provide high-precision, low-friction linear motion guidance; or, the transverse guide rails 7 can also be sliding guide rails, such as sliding bushings made of polymer materials that cooperate with the guide rails to achieve smooth sliding.

[0041] The slider 8 can be a linear bearing slider 8 that mates with a linear rolling guide rail, and it typically contains rolling elements to achieve low-friction sliding; alternatively, the slider 8 can also be a sliding block that mates with a sliding guide rail, and it is typically made of wear-resistant material; the guide screw 9 can be a ball screw, which has high transmission efficiency and positioning accuracy, and can efficiently convert rotary motion into linear motion; alternatively, the guide screw 9 can also be a trapezoidal screw, which has a relatively simple structure and a certain self-locking function; the first driving element 10 can be a servo motor, which achieves high-precision positioning and speed control through closed-loop control; alternatively, the first driving element 10 can also be a stepper motor, which achieves precise stepping movement through pulse control; alternatively, it can also be a DC motor, which, together with a reduction mechanism and an encoder, achieves position control.

[0042] The movable frame is slidably mounted on these transverse guide rails 7 via sliders 8, ensuring its stability and low friction during movement. The guide screw 9 is rotatably mounted on the worktable 1 and threadedly engaged with the slider 8. When the first drive member 10 drives the guide screw 9 to rotate, the rotational motion of the screw is converted into the linear motion of the slider 8 through the threaded pair, thereby driving the movable frame to move precisely along the transverse guide rails 7.

[0043] As an optional implementation, the mobile frame includes: Two longitudinal beams 11 are respectively set on one side of the two sliders 8, and two sets of upper lifting platforms 4 and lower lifting platforms 5 are respectively slidably set on the two longitudinal beams 11 along the vertical direction. The upper crossbeam 12 is used to connect the tops of the two longitudinal beams 11; The lower crossbeam 13 is used to connect the bottoms of the two longitudinal beams 11; The distance acquisition unit is set on the upper crossbeam 12 and the lower crossbeam 13.

[0044] In this embodiment, the longitudinal beam 11 can be made of high-strength, high-rigidity profiles, such as rectangular steel pipes, aluminum alloy extruded profiles, or precision-machined solid guide rails, to ensure sufficient strength and stability during vertical movement. The upper crossbeam 12 and the lower crossbeam 13 connect the top and bottom of the two longitudinal beams 11 respectively, forming a closed frame structure. The crossbeam can be made of structural components that match the longitudinal beams 11, such as I-beams, square tubes, or thick plates. The two longitudinal beams 11 are firmly connected together by welding, bolting, or other mechanical connection methods to enhance the overall rigidity and torsional resistance of the entire mobile frame.

[0045] By constructing a rigid frame structure consisting of two longitudinal beams 11, an upper crossbeam 12, and a lower crossbeam 13 inside the moving frame of the horizontal adjustment mechanism, the structural stability and deformation resistance of the entire polishing mechanism are significantly improved. Specifically, the two longitudinal beams 11 are respectively set on opposite sides of the two sliders 8, providing a solid and precise vertical sliding support surface for the upper lifting platform 4 and the lower lifting platform 5 in the lifting mechanism. The upper crossbeam 12 and the lower crossbeam 13 are respectively connected to the top and bottom of the two longitudinal beams 11, rigidly connecting the entire structure into a whole. This effectively resists the twisting and deformation that may occur during horizontal movement and vertical adjustment, ensuring the accuracy and stability of the relative position of the upper grinding roller 2 and the lower grinding roller 3 during polishing operations. Even under high-speed movement or frequent spacing adjustments, a high-precision polishing effect can be maintained.

[0046] In addition, the distance acquisition unit is set on the upper crossbeam 12 and the lower crossbeam 13, so that during the horizontal movement, the distance of the part to be polished area can be collected in real time, in multiple points or redundantly from multiple positions or different heights. This provides the control unit with more comprehensive and accurate data, so as to achieve precise adjustment of the distance between the upper grinding roller 2 and the lower grinding roller 3, which significantly improves the adaptability and polishing accuracy of the polishing device when processing irregular parts.

[0047] As an optional implementation, the lifting mechanism further includes: Two longitudinal guide rails 14 are respectively set on opposite sides of two longitudinal beams 11, and the upper lifting platform 4 and the lower lifting platform 5 are slidably set on the longitudinal guide rails 14. The double-ended lead screw 15 is rotatably mounted on the movable frame, and the two threaded sections of the double-ended lead screw 15 are respectively threadedly engaged with the upper lifting platform 4 and the lower lifting platform 5. The second driving component 16 is mounted on the movable frame and is used to drive the bidirectional lead screw 15 to rotate so that the upper lifting platform 4 and the lower lifting platform 5 move in opposite directions.

[0048] In this embodiment, the two longitudinal guide rails 14 can be linear rolling guide rails, such as ball guide rails or roller guide rails, or sliding guide rails, such as dovetail guide rails or rectangular guide rails. The bidirectional lead screw 15 is a lead screw with threads in two directions. By rotating it, it can simultaneously drive two nuts to move in opposite directions or at different speeds. Its function is to convert rotational motion into linear motion in two directions to synchronously and in opposite directions drive the upper lifting platform 4 and the lower lifting platform 5. The bidirectional lead screw 15 can be a left- or right-hand threaded lead screw, or a lead screw with two threaded sections having different pitches, or it can be achieved through differential threads. The second driving component 16 can be a stepper motor, servo motor, or DC motor, etc., and is connected to the bidirectional lead screw 15 through a reducer or coupling.

[0049] As an optional implementation, the distance acquisition unit includes: Mounting beam 17 is mounted on the upper crossbeam 12 and the lower crossbeam 13. Mounting beam 17 is perpendicular to the upper crossbeam 12 and the lower crossbeam 13, and its two ends extend to both sides of the upper grinding roller 2 and the lower grinding roller 3. Distance collectors 18 are positioned at both ends of the mounting beam 17 to collect the distance to the area of ​​the part to be polished.

[0050] In this embodiment, the mounting beam 17 can be a metal rod, profile, or plate with sufficient rigidity to ensure that it will not deform during operation, thereby guaranteeing the accuracy of distance acquisition. The mounting beam 17 can be made of aluminum alloy, stainless steel, or high-strength engineering plastics, etc. Its main function is to provide a stable mounting base for the distance acquisition device 18 and position it at a specific measurement location.

[0051] Distance acquisition units 18 are positioned at both ends of the mounting beam 17, enabling them to collect distance data from the sides of the upper and lower grinding rollers 2 and 3, i.e., the edges of the area to be polished on the part. This allows the distance acquisition unit to obtain distance information of the area to be polished on the part, thus providing a more comprehensive understanding of the complex surface contours of the irregularly shaped part. As the moving frame moves along the length of the part, the distance acquisition units 18 on the mounting beam 17 continuously collect distance data at different positions on the part. The collected data is then transmitted to the control unit. Based on this more comprehensive and accurate distance data, the control unit can more accurately determine the relative positions of the upper and lower grinding rollers 2 and 3 with the surface of the part, and then more precisely adjust the lifting mechanism to achieve dynamic adjustment of the distance between the upper and lower grinding rollers 2 and 3, ensuring that the grinding rollers always polish the part at the optimal distance.

[0052] As an optional implementation, multiple sets of fixing mechanisms are provided on the worktable 1 along the length direction of the upper grinding roller 2.

[0053] In this embodiment, multiple sets of fixing mechanisms are provided on the workbench 1. These mechanisms can simultaneously fix multiple parts of the same type, allowing the polishing mechanism to polish multiple parts at the same time. The distance acquisition unit corresponds to one of the parts and acquires the distance between that part and the upper grinding roller 2 and the lower grinding roller 3. The control unit processes the acquired data and controls the lifting mechanism to move the upper grinding roller 2 and the lower grinding roller 3 up and down. This allows for polishing multiple parts of the same type with higher efficiency.

[0054] As an optional implementation, the fixing mechanism includes: A clamping seat 19 is disposed on the worktable 1, and the clamping seat 19 is provided with a clamping hole 20 for the end of the part to pass through; The clamping plate 21 is slidably disposed on one side of the clamping seat 19. The clamping plate 21 can be driven to move on the clamping seat 19 to cooperate with the clamping hole 20 to clamp and fix the end of the part.

[0055] In this embodiment, the clamping base 19 is the basic structure used to support and position parts and other clamping components. It is usually made of high-strength materials (e.g., steel, aluminum alloy or composite materials) to ensure sufficient rigidity and stability during clamping and polishing. The clamping base 19 can be designed as a box structure, frame structure or plate structure, and its specific shape can be optimized according to the size and shape of the parts to be processed and the layout of the overall device.

[0056] The clamping hole 20 is a channel for the part to enter the fixing mechanism. Its shape and size are usually matched with or slightly larger than the end profile of the part to be processed, so as to facilitate the insertion and removal of the part. The clamping hole 20 can be a simple circular or rectangular through hole, or it can be an irregular hole customized according to the specific cross-sectional shape of the irregular part, designed to provide initial positioning and support.

[0057] The clamping plate 21 is driven to move on the clamping seat 19. When the clamping plate 21 moves into the area of ​​the clamping hole 20, the clamping plate 21 pushes the end of the part during the movement, so that the end of the part abuts against the inner wall of the clamping hole 20. The clamping plate 21 and the clamping hole 20 cooperate to achieve clamping and fixing of the part. As an optional implementation, the fixing mechanism further includes a drive component, the drive component comprising: The drive screw 22 is rotatably mounted on the worktable 1. The drive screw 22 passes through all the clamping plates 21 and is threadedly engaged with all the clamping plates 21. The third driving component 23 is disposed on the worktable 1 and is in transmission cooperation with the driving screw 22.

[0058] In this embodiment, the clamping plate 21 is made of a material with certain hardness and wear resistance, such as metal alloy or engineering plastic. Its surface can be treated according to the material of the part and polishing requirements, such as increasing friction or avoiding damage. The longitudinal clamping plate can be designed to have a flat clamping surface to adapt to the end of the part with a regular shape; or, the longitudinal clamping plate can also be designed to have a V-groove, an arc groove or a replaceable clamp to adapt to the end shape of different irregular parts and improve the versatility and stability of clamping.

[0059] A T-slot is provided on the side of the clamping seat 19. The clamping plate 21 is slidably set on the clamping seat 19 by cooperating with the T-slot. The drive screw 22 passes through all the clamping plates 21 and is threadedly engaged with the clamping plates 21. The third drive component 23 can take various forms. For example, it can be an electric motor, such as a servo motor or a stepper motor, which can achieve fine adjustment of the clamping action by precisely controlling its speed and angle; it can also be a pneumatic motor or a hydraulic motor, which can achieve power output by air pressure or hydraulic pressure. Through the transmission cooperation between the third drive component 23 and the drive screw 22, the synchronous start of all fixed components can be achieved, and multiple parts can be clamped and fixed at the same time.

[0060] In other embodiments, two drive screws 22 can be provided, with the two drive screws 22 passing through both ends of the clamping plate 21 respectively. For example, one drive screw is located below the clamping hole 20, and the other drive screw 22 is located above the clamping hole 20. The two drive screws 22 can rotate synchronously through belts, gears, etc., which can reduce the jamming of the clamping plate 21 during movement.

[0061] As an optional implementation, the worktable 1 is hollowed out to form a polishing area, the upper grinding roller 2 and the lower grinding roller 3 are located in the polishing area, and the fixing mechanism is disposed on both sides of the polishing area.

[0062] In this embodiment, a polishing area is formed by slotting on the worktable 1, so that the lower grinding roller 3 works under the worktable 1 via the longitudinal guide rail 14, and the upper grinding roller 2 works on the worktable 1 to grind and polish the parts clamped and fixed on the worktable 1.

[0063] As an optional implementation, two sliding plates 6 are provided on both sides of the polishing area on the worktable 1, which are used to install two sets of the fixing mechanisms respectively. The sliding plates 6 can be driven to move on the worktable 1 to adjust the distance between the fixing mechanisms on both sides of the polishing mechanism.

[0064] In this embodiment, a sliding groove or rail is provided on the worktable 1 to form a sliding engagement with the slide plate 6, allowing the slide plate 6 to slide on the worktable 1. In this embodiment, the driving method is implemented by an electric push cylinder 26, but a cylinder, lead screw motor, or other mechanism can also be used to drive it, allowing the slide plate 6 to move on the worktable 1. By connecting the slide plate 6 to the telescopic end of the electric push cylinder 26, the slide plate 6 can be moved by the electric push cylinder 26, adjusting the distance between the two sets of fixing mechanisms, so that the fixing mechanisms can fix parts of different lengths, making it more versatile.

[0065] As an optional implementation, the workbench 1 is provided with limit plates 24 on both sides of the slide plate 6, and the limit plates 24 are provided with pressure plates 25 on the top, which are attached to the two sides of the top of the slide plate 6.

[0066] In this embodiment, the limiting plates 24 on both sides of the slide plate 6 can guide the sliding of the slide plate 6. The cooperation of the two limiting plates 24 forms a sliding groove for the slide plate 6 to slide. The pressure plate 25 on the limiting plate 24 can act as a longitudinal fiber for the slide plate 6. When the end of the slide plate 6 moves into the polishing area, the pressure plate 25 can press down the part that is still on the worktable 1, so as to prevent the front end of the slide plate 6 from tilting downward under force, so that the pressure plate 25 can only move within the extension and retraction stroke of the electric push cylinder 26.

[0067] The above are merely preferred embodiments of this application and do not limit the patent scope of this application. Any equivalent structural or procedural transformations made using the content of this application's specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this application.
