Abstract

This invention discloses an angle-adjustable grinding equipment adapted to irregularly shaped products, relating to the field of spherical grinding technology. It includes a processing table, control panel, support mechanism, lifting mechanism, lifting frame, fixing mechanism, angle adjustment mechanism, and grinding wheel. The equipment achieves multi-point external support for workpieces of different diameters through the adaptive radial adjustment of the support mechanism. Combined with the bidirectional tensioning of the fixing mechanism, it completes the internal clamping and positioning of workpieces with through holes. The angle adjustment mechanism then enables continuous 360° adjustment of the grinding wheel's three-dimensional grinding angle. These three components work together without requiring tooling changes, enabling one-time high-precision grinding of various irregularly shaped spherical surfaces. This effectively reduces tooling preparation costs, while improving processing efficiency and forming accuracy compared to traditional equipment.

Description

Technical Field

[0001] This invention relates to the field of spherical grinding technology, and more particularly to a grinding equipment with adjustable angles to adapt to irregularly shaped products. Background Technology

[0002] Spherical grinding equipment refers to specialized machine tools used for grinding spherical or spherical workpieces. Its core function is to remove surface material from the workpiece through the relative motion between the grinding wheel and the spherical surface of the workpiece to achieve specified dimensional accuracy, shape accuracy, and surface roughness. Irregularly shaped spherical workpieces refer to non-standard, complete spherical parts, including spheres with a central through-hole, partially spherical parts, ball valve balls, articulated balls, and various spherical parts with asymmetrical features. These workpieces are widely used in valve manufacturing, precision machinery, aerospace, and medical devices.

[0003] Currently, most traditional spherical grinding equipment is designed for standard spheres, and its tooling fixtures and grinding angle adjustment mechanisms are all of fixed specifications. This has significant limitations when processing irregularly shaped spherical workpieces with through holes. For non-standard workpieces with different diameters and different spherical curvatures, it is usually necessary to pre-customize special clamping fixtures, and the grinding angle can only be adjusted in segments within a limited range. This makes it difficult to meet the processing needs of special structural workpieces such as local spherical surfaces and asymmetrical spherical surfaces. Therefore, there is an urgent need for improvement. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, the purpose of this invention is to provide an angle-adjustable grinding equipment suitable for irregular products, which aims to solve the technical problems of the above-mentioned traditional ball mill equipment with fixed tooling angles, difficulty in processing irregular spherical surfaces with holes, the need for customized fixtures, narrow adjustment range, and unsuitability for asymmetrical parts.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are: 1. Through the guiding cooperation between the arc groove and the transmission roller in the support mechanism, when the turntable rotates, the oblique motion component of the arc groove is converted into the radial driving force of the transmission roller, which drives multiple sets of support inclined plates to synchronously retract inward or expand outward along the radial direction. It can achieve adaptive multi-point external support positioning for spherical workpieces of different diameters without adjusting a single support point. This avoids the tedious operation of adjusting point by point and ensures that the force on each support point is uniform and the coaxiality accuracy of the support is higher. 2. Through the threaded engagement of the bidirectional lead screw and two moving nuts in the fixing mechanism, when the third motor drives the bidirectional lead screw to rotate, the two moving nuts drive the corresponding tapered chucks to move synchronously towards each other. After being inserted into the center through hole of the workpiece, a radial tension fixing can be formed from the inside, forming a double positioning constraint with the external support inclined plate, completely eliminating the risk of circumferential rotation and axial movement of the workpiece during the processing, and greatly improving the reliability and consistency of clamping and positioning. 3. Through the transmission cooperation between the drive gear, transmission gear and the ring track in the angle adjustment mechanism, the fourth motor drives the rotating frame to rotate 360° continuously around the workpiece axis. At the same time, in conjunction with the pitch angle adjustment of the angle adjustment frame around the third rotating roller, the grinding angle of the grinding wheel can be adjusted arbitrarily and continuously in three-dimensional space. Various non-standard spherical surfaces, partial spherical surfaces and asymmetric spherical surfaces can be ground in one go without changing the tooling or recalibrating the reference. This reduces the tooling investment cost and significantly improves the processing efficiency and forming accuracy of irregular spherical workpieces. Attached Figure Description

[0030] Reference Figures 1 to 8 The present invention provides a further description of an embodiment of an angle-adjustable grinding equipment for irregularly shaped products.

[0031] An angle-adjustable grinding equipment for irregularly shaped products includes a processing table 1, a control panel 2, a support mechanism, a lifting mechanism, a lifting frame 3, a fixing mechanism, an angle adjustment mechanism, and a grinding wheel 4. Control panel 2 is fixedly mounted on the upper surface of processing table 1; Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 In a preferred embodiment, the support mechanism is located at the center of the processing table 1 and is used to support irregular spherical workpieces of different diameters at multiple points. The support mechanism includes a first motor 5, a first rotating roller 6, a turntable 7, an arc groove 8, and a clamping assembly. The first motor 5 is fixedly mounted on the bottom surface of the processing table 1 and is electrically connected to the control panel 2; The first rotating roller 6 is rotatably mounted on the processing table 1, and one end is fixedly connected to the output end of the first motor 5; Turntable 7 is fixedly mounted at the other end of the first roller 6; Multiple arc-shaped grooves 8 are arranged in a ring on the turntable 7. This design allows the arc-shaped grooves 8 to drive the transmission rollers 11 in the clamping assembly to move when the turntable 7 rotates, thereby driving the I-beam slide 10 to move radially within the rectangular groove 9. This enables the inclined plate 12 to adaptively clamp and position the workpiece, ensuring the stability of irregularly shaped spherical workpieces of different diameters during the processing. Multiple clamping components are arranged in a ring on the processing table 1. The clamping components include a rectangular groove 9, an I-shaped slide table 10, a transmission roller 11, and a support inclined plate 12. The rectangular groove 9 is opened on the machining table 1; this design restricts the I-beam slide table 10 to linear reciprocating motion within the rectangular groove 9, avoiding deflection or swaying during radial movement, and ensuring the stability and accuracy of the movement of the support inclined plate 12. The I-beam slide 10 is disposed in the rectangular groove 9 and is slidably connected to the processing table 1; The transmission roller 11 is disposed through the arc groove 8, and one end is fixedly connected to the bottom end of the I-shaped slide 10, while the top end of the transmission roller 11 is fixedly connected to the bottom end face of the I-shaped slide 10. The bottom end face of the support inclined plate 12 is fixedly set on the top end face of the I-beam slide table 10. This setting allows the support inclined plate 12 to automatically adjust the support position according to the change of the workpiece diameter, ensuring that spherical workpieces of different specifications can obtain stable multi-point support. During operation, the first motor 5 is started via the control panel 2. The first motor 5 drives the first roller 6, which is fixedly connected to its output end, to rotate. The first roller 6 drives the turntable 7 to rotate. Since the I-beam slide 10 can only move in a straight line along the rectangular groove 9 under the guidance constraint of the rectangular groove 9, the turntable 7 drives the I-beam slide 10 to move radially along the rectangular groove 9 through the arc groove 8 and the transmission roller 11, which is fixedly connected to the I-beam slide 10. This drives the support inclined plate 12 to move synchronously, thus completing the adaptive multi-point support and clamping of spherical workpieces of different diameters and irregular shapes.

[0032] Reference Figure 1 , Figure 3 , Figure 4 , Figure 5 , Figure 7 and Figure 8 In a preferred embodiment, the lifting mechanism is located on the upper side of the processing table 1 and is used to drive the lifting frame 3 to move up and down. The lifting mechanism includes a eccentric column 13, a lifting groove 14, a second motor 15, a screw 16, a threaded sleeve 17 and a lifting slide 18. The offset column 13 is fixedly installed on the upper side surface of the processing table 1; The lifting groove 14 is provided on the eccentric column 13; The second motor 15 is fixedly mounted on the top surface of the offset column 13 and is electrically connected to the control panel 2; The screw 16 is rotatably mounted on the offset column 13, and one end is fixedly connected to the output end of the second motor 15; The threaded sleeve 17 is fitted onto the screw 16 and is threadedly connected to the screw 16; The lifting slide 18 is fixedly mounted on the threaded sleeve 17, slidably connected to the offset column 13, and fixedly connected to the lifting frame 3; Two lifting guide rods 40 are symmetrically fixed on the processing table 1, and two lifting limit plates 41 are symmetrically fixed on the lifting frame 3. A sliding sleeve 42 is fixed on the lifting limit plate 41, and the sliding sleeve 42 is slidably connected to the lifting guide rod 40. The lifting frame 3 is mounted on the lifting mechanism.

[0033] During operation, the second motor 15 is started via the control panel 2. The second motor 15 drives the screw 16, which is fixedly connected to the output end, to rotate. The rotation of the screw 16 drives the threaded sleeve 17, which is sleeved on it, to move axially. This drives the lifting slide 18, which is fixedly connected to the threaded sleeve 17, to move vertically up and down along the lifting groove 14 on the offset column 13. The lifting slide 18 drives the lifting frame 3 to move up and down synchronously. During this process, the sliding sleeve 42 on the lifting limit plate 41 slides along the lifting guide rod 40, providing auxiliary guidance and support for the lifting frame 3. This effectively counteracts the lateral torque and ensures the stability and verticality accuracy of the lifting frame 3 during its up and down movement, thereby achieving precise adjustment of the workpiece processing height. This continues until the rotation axis of the third roller 33, the central axis of the two conical chucks 24, and the central through hole of the spherical workpiece of the irregular product are all located in the same horizontal plane.

[0034] Reference Figure 2 , Figure 5 , Figure 7 and Figure 8 In a preferred embodiment, the fixing mechanism is set on the lifting mechanism and is used to insert into the central through hole of the irregular spherical workpiece to achieve fixing. The fixing mechanism includes a limiting groove 19, a third motor 20, a two-way lead screw 21, a moving nut 22, a moving plate 23 and a conical chuck 24. Two limiting slots 19 are symmetrically provided on the lifting frame 3; The third motor 20 is fixedly mounted on the lifting frame 3 and electrically connected to the control panel 2; The bidirectional lead screw 21 is rotatably mounted on the lifting frame 3, and one end is fixedly connected to the output end of the third motor 20; Two movable nuts 22 are symmetrically arranged on the bidirectional lead screw 21 and are threadedly connected to the bidirectional lead screw 21; Two movable plates 23 are slidably disposed in the limiting groove 19 and are fixedly connected to the movable nut 22; Two conical chucks 24 are fixedly mounted on a movable plate 23. This design allows for radial clamping and fixation of irregularly shaped spherical workpieces from the inside, ensuring the workpiece remains stable during processing and preventing displacement or shaking caused by cutting forces.

[0035] During operation, the third motor 20 is started via the control panel 2. The third motor 20 drives the bidirectional lead screw 21, which is fixedly connected to its output end, to rotate. The rotation of the bidirectional lead screw 21 drives the two movable nuts 22, which are symmetrically arranged on it, to move axially towards each other or away from each other. This, in turn, drives the two movable plates 23, which are fixedly connected to the movable nuts 22, to slide synchronously within the limiting groove 19, so that the two conical chucks 24 move closer to each other or further away from each other. When the conical chucks 24 are inserted into the central through hole of the irregular shaped spherical workpiece and spread apart, the radial clamping and fixing of the workpiece is achieved, ensuring that the workpiece does not shift or rotate during subsequent grinding.

[0036] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 7 In a preferred embodiment, the angle adjustment mechanism is mounted on the lifting frame 3 and is used to adjust the grinding angle of the grinding wheel 4. The angle adjustment mechanism includes a side frame 25, a fourth motor 26, a second rotating roller 27, a drive gear 28, a transmission gear 29, a ring track 30, a rotating frame 31, and an angle adjustment assembly.

The angle adjustment assembly includes a fifth motor 32, a third rotating roller 33, an angle adjustment frame 34, and a lifting drive unit. The fifth motor 32 is fixedly mounted on the rotating frame 31 and is electrically connected to the control panel 2; The third roller 33 is rotatably mounted on the rotating frame 31, and one end is fixedly connected to the output end of the fifth motor 32. The rotation axis of the third roller 33 and the central axis of the two conical chucks 24 are located in the same horizontal plane. Angle adjustment bracket 34 is fixedly mounted on the third rotating roller 33; The lifting drive unit is mounted on the angle adjustment frame 34. The lifting drive unit includes an electric telescopic rod 35, a guide groove 36, a moving frame 37, a sixth motor 38, and a drive roller 39. The electric telescopic rod 35 is fixedly installed on the top of the angle adjustment frame 34 and is electrically connected to the control panel 2; Two guide slots 36 are provided on the angle adjustment bracket 34; The movable frame 37 is slidably disposed in the guide groove 36, and its top end is fixedly connected to the output end of the electric telescopic rod 35; The sixth motor 38 is fixedly mounted on the side end face of the movable frame 37 and is electrically connected to the control panel 2; The drive roller 39 is rotatably mounted on the movable frame 37, with one end fixedly connected to the output end of the sixth motor 38 and fixedly connected to the grinding wheel 4; Grinding wheel 4 is mounted on the angle adjustment mechanism; During operation, the fourth motor 26 is activated via the control panel 2. The fourth motor 26 drives the second roller 27, which is fixedly connected to its output end, to rotate. The rotation of the second roller 27 drives the drive gear 28 to rotate. The drive gear 28, through meshing with the transmission gear 29, drives the transmission gear 29 and the rotating frame 31 fixed thereon to rotate along the annular track 30, thereby adjusting the spatial angle of the angle adjustment component. Simultaneously, the fifth motor 32 is activated via the control panel 2. The fifth motor 32 drives the third roller 33 to rotate, which in turn drives the angle adjustment frame 34 to rotate around the axis of the third roller 33, achieving fine adjustment of the grinding angle of the grinding wheel 4. During this process, the sixth motor 38 is activated via the control panel 2. The sixth motor 38 drives the drive roller 39 and the grinding wheel 4 to rotate at high speed for grinding operations. According to the processing requirements, the electric telescopic rod 35 is extended and retracted via the control panel 2. The electric telescopic rod 35 pushes the moving frame 37 to slide along the guide groove 36, thereby driving the grinding wheel 4 to move closer to or away from the workpiece surface, achieving precise control of the grinding depth.

[0037] Working Principle: In operation, the irregularly shaped spherical workpiece to be processed is first placed on the support mechanism of the processing table 1. The first motor 5 is activated via the control panel 2, driving the turntable 7 to rotate. The arc-shaped groove 8 on the turntable 7 drives the transmission roller 11 to move, which in turn drives the I-beam slide 10 to move radially along the rectangular groove 9. This causes multiple support inclined plates 12 to simultaneously move towards the center or expand outwards until they are tightly fitted to the outer surface of the workpiece, achieving adaptive multi-point support and initial positioning according to workpieces of different diameters. Subsequently, the second motor 15 is activated, driving the screw 16 to rotate. This causes the threaded sleeve 17 and the lifting slide 18 to move vertically along the offset column 13, thereby adjusting the height of the lifting frame 3 and aligning the axis of the conical chuck 24 of the fixing mechanism with the through hole at the center of the workpiece. Next, the third motor 20 is started, which drives the bidirectional lead screw 21 to rotate. The rotation of the bidirectional lead screw 21 drives the two movable nuts 22 symmetrically arranged on it to move axially towards each other or away from each other. This, in turn, drives the two movable plates 23 fixedly connected to the movable nuts 22 to slide synchronously in the limiting groove 19, so that the two conical chucks 24 are inserted into the center through hole of the workpiece and clamped, radially clamping and fixing the workpiece to ensure that the workpiece is stable and without displacement during processing. According to the grinding process requirements, the fourth motor 26 is started through the control panel 2. The fourth motor 26 drives the second rotating roller 27 fixedly connected to its output end to rotate. The rotation of the second rotating roller 27 drives the drive gear 28 to rotate. The drive gear 28, through meshing with the transmission gear 29, drives the transmission gear 29 and the rotating frame 31 fixed on it to rotate along the annular track 30, thereby adjusting the spatial angle of the angle adjustment component. At the same time, the fifth motor 32 is started through the control panel 2. The fifth motor 32 drives the third rotating roller 33 to rotate, which in turn drives the angle adjustment frame 34 to rotate around the axis of the third rotating roller 33, realizing the fine adjustment of the grinding angle of the grinding wheel 4. Finally, the sixth motor 38 is started to drive the grinding wheel 4 to rotate at high speed. By controlling the extension and retraction of the electric telescopic rod 35, the feed depth of the grinding wheel 4 is adjusted to perform precise grinding on the workpiece surface. The entire processing is centrally controlled through the control panel 2, realizing automatic clamping, multi-angle adaptation, and high-precision grinding of irregularly shaped spherical workpieces, effectively improving processing efficiency and product quality.
