Description

Technical Field

[0001] The invention relates to the technical field of mechanical processing, in particular to a spherical base surface grinding ultra-precision integrated machine tool. Background Art

[0002] The invention patent application with Chinese publication number CN115922452A discloses a method for achieving spherical base surface grinding by the Fancheng method. The patent is provided with a driving disk component, the driving disk rotates axially vertically, and the roller is located above the driving disk. The driving disk provides a rotational power to the roller during rotation. The cooperation of the clamping wheel and the stop block applies vertical pressure to the roller and applies a limiting function to realize the roller's self-rotation.

[0003] The driving disc generates centrifugal force during rotation. Although the block can offset the tangential motion force of the roller through the driving disc component, after the block is lifted, the roller is affected by the rotational force and centrifugal force applied by the driving disc component, and the roller will move away from the driving disc component. The distance between the roller and the processing grinding wheel is small, and the roller is thrown outward by the centrifugal force of the driving disc. The roller can easily touch the grinding wheel and cause damage to the machine. There must be no obstruction in the processing area of ​​the roller, so it is impossible to set an independent guide track on the top of the driving disc component to control the movement of the roller.

[0004] The drive disc component needs to rotate, and there is no fixed structure on the surface of the drive disc component to guide the roller movement. Vertical movement space for the pressure wheel, pressure block, and stopper needs to be reserved above the roller, and surrounding ribs cannot be set on the outer circumference of the drive disc component. Therefore, how to discharge the processed roller within a controllable range is the first problem to be solved in continuous processing.

[0005] The roller has a small diameter, and the roller spherical surface rotates very quickly during processing. The processing time of a single roller is short, so the material needs to be stacked in advance during continuous roller processing. Only one roller is processed at a time, and it is affected by the rotation of the clamping wheel. If two rollers enter the processing area at the same time or both rollers are affected by the clamping wheel, the rollers cannot be positioned and are easy to fly out, causing safety hazards. The diameter of the drive disc component is large and the drive disc component is a moving workpiece, which is not conducive to establishing a feeding structure.

[0006] In summary, it is necessary to solve the problem of determining the roller discharge position, and also to solve the problem of the dynamic and static combination of the roller feeding mechanism and the driving disk, so as to ensure that the roller can achieve continuous feeding processing in a limited space. Summary of the invention

[0007] The purpose of the present invention is to provide a ball-base surface grinding ultra-precision integrated machine tool, which is based on the motion trajectory of the lifting drive clamping locator. The regional critical barrier bracket uses the relationship between the exposed contact point of the roller and the friction force to limit the roller with an outward movement tendency to move inward or hinder the roller from further moving outward, so as to avoid the roller from contacting the grinding wheel when discharging, and uses the characteristics of the distance between the three-side frame axis and the arc track to achieve material positioning and feeding control. The non-pressed structure will not affect the roller and can meet the limit requirements of a slippery environment. The structure is simple and can be coupled with the lifting drive clamping locator, reducing maintenance costs and use costs. The above structure does not require a power source to further simplify the structure, reduce the volume, and realize the feeding and discharging problems encountered in the continuous processing of the three-point limit spin-type machine tool, so that the continuous processing of the three-point limit spin-type machine tool is more efficient and stable, so as to solve the problems raised in the above background technology.

The regional critical blocking bracket and the single-material lifting feeder are located on both sides of the lifting drive clamping positioner.

[0009] As a further solution of the present invention: the driving disk component has a processing area near the grinding wheel component, and the processing area includes a temporary retention area, a grinding area and a swing-out area. The arc track is tangent to the driving disk component at the junction of the temporary retention area and the grinding area. During the downward movement of the lifting drive clamping positioner, the single material lifting and feeding device fixes the single material in the arc track in the temporary retention area, and the regional critical barrier bracket moves away from the swing-out area. During the upward movement of the lifting drive clamping positioner, the single material lifting and feeding device releases a single material into the grinding area at a time, and the regional critical barrier bracket moves close to the swing-out area.

[0010] As a further solution of the present invention: the single-material lifting and feeding device includes a rotating rod, an extension rod, and an elastic rotator. The rotating rod rotates beside the lifting drive clamping locator through the elastic rotator. One end of the rotating rod is fixed with a resistance rod. The sliding plate of the lifting drive clamping locator is fixedly connected with a push pin that cooperates with the resistance rod.

[0011] As a further solution of the present invention: the other end of the rotating rod is fixedly connected to an extension rod, and one end of the extension rod close to the arc track is rotatably connected to a three-side frame.

[0012] As a further solution of the present invention: when the lifting drive clamping positioner descends to the lowest point, the distance between the rotation axis of the three-sided frame and the bottom surface of the arc track is smaller than the side length of the three-sided frame; when the lifting drive clamping positioner rises to the highest point, the distance between the rotation axis of the three-sided frame and the bottom surface of the arc track is greater than the side length of the three-sided frame.

[0013] As a further solution of the present invention: the shape of the regional critical barrier bracket is L-shaped, the regional critical barrier bracket is rotatably connected to the frame above the driving disk component, the top of the lifting drive clamping locator is fixedly connected with a vertical rod, the end of the regional critical barrier bracket is fixedly connected with a blocking baffle, the rotation point of the regional critical barrier bracket is located between the blocking baffle and the driving disk component, and the blocking baffle is located at the intersection of the edge of the rotation-out zone and the arc edge of the driving disk component.

[0014] As a further solution of the present invention: the width of the discharge track is greater than the width of the arc track, a blocking plate is arranged above the driving disk component, the blocking plate does not contact the driving disk component, and the blocking plate is flush with a side plate of the discharge track close to the driving disk component.

[0015] As a further solution of the present invention, the upper part of the lifting drive clamping positioner is driven to move up and down by a driving member: As a further solution of the present invention, the driving disk component rotates horizontally, the arc track is inclined with respect to the horizontal plane, and the end of the arc track close to the driving disk component is the lowest end; As a further solution of the present invention, one end of the arc-shaped track away from the driving disk component extends to the outside of the driving disk component body.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This technical solution is based on the motion trajectory of the lifting drive clamping locator. The regional critical barrier bracket uses the relationship between the exposed contact point of the roller and the friction force to limit the inward movement of the roller with an outward movement trend or hinder the roller from further outward movement, thereby avoiding contact between the roller and the grinding wheel during discharge, and solving the discharge problem of the three-point limit spin molding method machine tool processing.

[0017] The single-material lifting feeder adjusts the position of the three-side frame with the lifting drive clamping positioner, and uses the characteristics of the distance between the three-side frame axis and the arc track to realize the control of material positioning and feeding. The non-pressed structure will not affect the roller and can meet the limit requirements of slippery environments. The structure is simple and can be coupled with the lifting drive clamping positioner, reducing maintenance costs and use costs. The above structure does not require a power source to further simplify the structure and reduce the volume.

[0018] In summary, this technical solution solves the feeding and discharging problems encountered in the continuous processing of the three-point limit rotation fan method machine tool, making the continuous processing of the three-point limit rotation fan method machine tool more efficient and stable.

DETAILED DESCRIPTION

[0021] See also Figure 1-Figure 5: In this embodiment: it includes a grinding wheel component 1 and a driving disk component 2. The edge of the driving disk component 2 is symmetrically provided with an arc track 3 and a discharge track 4. A lifting drive clamping positioner 5 is vertically slidably connected above the driving disk component 2. A driving pressure wheel 51 and a top block 53 are installed on the side of the lifting drive clamping positioner 5. It also includes a regional critical blocking bracket 7 and a single material lifting feeder 8 that move synchronously up and down with the lifting drive clamping positioner 5. The regional critical blocking bracket 7 and the single material lifting feeder 8 are located on both sides of the lifting drive clamping positioner 5.

[0022] In this embodiment, the driving disk component 2 serves as the rotational driving force of the roller and the driving force for the roller conveying. The lifting driving clamping positioner 5 is driven down by the driving member 6. The top block 53, the driving pressure wheel 51, and the driving disk component 2 form a three-point limit to make the roller spin. The grinding wheel component 1 adjusts the contact angle with the roller to drive the grinding wheel to spin, and the grinding wheel performs spherical processing on the roller.

[0023] In order to solve the problem of orderly conveying of rollers and realizing directional discharge of rollers by means of the power of the driving disc component 2 after the driving disc component 2 is set, the following improvements are made in this embodiment: Improvement of the feeding structure: comprising an arc track 3, which is the connection area between the feeding area and the processing area 100, the material is fed through one end of the arc track 3, the driving disc component 2 rotates horizontally, the arc track 3 is inclined with the horizontal plane, and the end of the arc track 3 close to the driving disc component 2 is the lowest end. The arc track 3 is tangent to the driving disc component 2 at the junction of the temporary retention area 101 and the grinding area 102.

[0024] Feeding structure improvement effect: please refer to Figure 3 , the roller is put in through one end of the arc track 3, the arc track 3 is curved and tangent to the driving disk component 2, and the roller at one end of the arc track 3 close to the driving disk component 2 can directly enter the grinding area 102 through the temporary area 101, and the driving disk component 2, the driving pressure wheel 51, and the top block 53 cooperate to drive the roller to spin in the grinding area 102. The rollers are accumulated at one end of the arc track 3 close to the driving disk component 2 under the influence of gravity. The arc track 3 is located above the driving disk component 2, and the driving disk component 2 and the arc track 3 are relatively slidably connected. The arc track 3 can be fixed to the frame above the driving disk component 2. The rollers can reach the grinding area 102 through the arc track 3 with the help of gravity.

[0025] The difference between the feeding structure and the existing structure: the form of suspension conveying can convey the rollers to the grinding area 102 more quickly and accurately. The diameter of the driving disc component 2 is large, but the area of ​​the grinding area 102 is small. If the rollers are placed through other positions of the driving disc component 2, the rollers are easy to fly outward from the driving disc component 2 in the tangential direction when the driving disc component 2 rotates.

[0026] In this embodiment, in order to solve the problem that during the discharge process of the roller after the grinding area 102 is processed, the roller moves to a position away from the center of the driving disk component 2 through the joint between the grinding area 102 and the rotation-out area 103, causing the roller to collide with the grinding wheel of the grinding wheel component 1.

[0027] In order to solve this problem, the present embodiment makes the following improvements: the driving disk component 2 has a processing area 100 near the grinding wheel component 1, and the processing area 100 includes a temporary area 101, a grinding area 102 and a swing-out area 103. During the downward movement of the lifting and driving clamping positioner 5, the regional critical barrier bracket 7 moves away from the swing-out area 103. During the upward movement of the lifting and driving clamping positioner 5, the regional critical barrier bracket 7 moves close to the swing-out area 103.

[0028] The specific implementation method is as follows: the shape of the regional critical barrier bracket 7 is L-shaped, the regional critical barrier bracket 7 is rotatably connected to the frame above the driving disk component 2, the top of the lifting drive clamping locator 5 is fixedly connected with a vertical rod 52, and the end of the regional critical barrier bracket 7 is fixedly connected with a blocking baffle 71, and the rotation point of the regional critical barrier bracket 7 is located between the blocking baffle 71 and the driving disk component 2, and the blocking baffle 71 is located at the intersection of the edge of the rotation-out area 103 and the arc edge of the driving disk component 2.

[0029] Improvement purpose: Please refer to Figure 2 , the roller is close to the grinding wheel of the grinding wheel component 1 in the grinding area 102, and the diameter of the grinding wheel is larger than the diameter of the roller. The driving pressure wheel 51 and the top block 53 rise, and the roller loses its limiting function. During the rotation of the driving disk component 2, the roller will separate from the driving disk component 2. The roller is not limited in other directions, and the roller is easy to move in a direction away from the center of the driving disk component 2, resulting in the roller easily contacting with the grinding wheel of the grinding wheel component 1 and causing damage.

[0030] The improved usage is as follows: When the lifting drive clamping positioner 5 is in the lifting state, the driving pressure wheel 51 and the top block 53 are raised, the lifting drive clamping positioner 5 pushes the vertical rod 52 to rise, the end of the regional critical blocking bracket 7 away from the grinding wheel component 1 is raised, and the end of the regional critical blocking bracket 7 close to the grinding wheel component 1 is lowered, and the blocking baffle 71 moves toward the rotation-out area 103. If the roller passes through the grinding area 102 and enters the rotation-out area 103 and has a tendency to move outward, the blocking baffle 71 will block the part of the roller exposed in the driving disk component 2, and the contact surface between the roller and the driving disk component 2 is affected by the friction force, forcing the roller to rotate toward the center of the driving disk component 2.

[0031] The reason for setting the regional critical barrier bracket 7 to rotate is as follows: In order to maximize the inward rotation effect of controlling the driving disk component 2, the barrier baffle 71 needs to contact the side wall of the driving disk component 2. The barrier baffle 71 is easily worn due to long-term friction, and sharp edges will be produced after the barrier baffle 71 is worn, and the sharp edges will cause damage to the roller contact. Therefore, the regional critical barrier bracket 7 only needs to control the barrier baffle 71 to contact with the driving disk component 2 when the lifting drive clamping positioner 5 is lifted. At the same time, when the regional critical barrier bracket 7 is closed, the barrier baffle 71 moves toward the driving disk component 2. If the barrier baffle 71 is reset when the material passes through the barrier baffle 71, the force of the barrier baffle 71 to reset to the center of the driving disk component 2 is applied to the roller, providing an inward force to the roller.

[0032] In order to solve the problem that the grinding area 102 has a small space, after the driving pressure wheel 51 is set, the double rollers fall or the distance between the processing roller and the roller to be processed is small, which causes the rollers to be unable to be positioned or even fly out, the following improvements are made in this embodiment: In this embodiment, during the downward movement of the lifting drive clamping positioner 5, the single material lifting and feeding device 8 fixes the single material in the arc track 3 in the temporary retention area 101. During the upward movement of the lifting drive clamping positioner 5, the single material lifting and feeding device 8 releases the single material into the grinding area 102 at a time. The single material lifting and feeding device 8 includes a rotating rod 81, an extension rod 82, and an elastic rotator 83. The rotating rod 81 rotates on the side of the lifting drive clamping positioner 5 through the elastic rotator 83. One end of the rotating rod 81 is fixed to the contact rod 84. A top pin cooperating with the interference rod 84 is fixedly connected to the sliding plate of the lowering drive clamping locator 5, and the other end of the rotating rod 81 is fixedly connected to the extension rod 82. The extension rod 82 is rotatably connected to the three-side frame 85 at one end close to the arc track 3. When the lifting drive clamping locator 5 descends to the lowest point, the distance between the rotation axis of the three-side frame 85 and the bottom surface of the arc track 3 is less than the side length of the three-side frame 85. When the lifting drive clamping locator 5 rises to the highest point, the distance between the rotation axis of the three-side frame 85 and the bottom surface of the arc track 3 is greater than the side length of the three-side frame 85.

[0033] Purpose of improvement: The processing area 100 is small and a large feeding structure cannot be used. The traditional pressing block structure uses the lifting drive clamping positioner 5 to move up and down to press down the roller in the arc track 3, which is not stable. The pressing block mainly uses downward pressure to apply to the roller to fix the roller. A large amount of coolant will be generated during the processing. The coolant reduces the friction in the processing area 100. The contact between the pressing block and the roller is linear, and the roller is easy to fall. It is necessary to apply greater downward pressure to the roller, which makes the arc track 3 easy to deform or the roller surface to be crushed. If the pressing block is arc-shaped, the pressing block cannot guarantee that the arc surface can accurately press the roller during each downward pressing process. If the pressing is not in place, multiple rollers will enter the drive disk component 2, causing safety hazards.

[0034] Improvement principle: Please refer to Figure 5 In the downward pressing stage of the driving pressure wheel 51, the sliding plate top pin of the lifting driving clamping positioner 5 limits the resistance rod 84, and a torsion spring is arranged in the elastic rotator 83, and the torsion spring in the elastic rotator 83 is in an undeformed state.

[0035] See also Figure 5 , the lifting drive clamping positioner 5 drops to the lowest point. Since the distance between the rotation axis of the three-sided frame 85 and the bottom surface of the arc track 3 is smaller than the side length of the three-sided frame 85, the three-sided frame 85 cannot rotate counterclockwise, so the roller cannot be separated from the three-sided frame 85.

[0036] The rising stage of the driving pressure wheel 51 is the stage of discharging and feeding. After the lifting driving clamping positioner 5 is lifted, the abutting rod 84 drives the rotating rod 81 to rotate, and the torsion spring of the elastic rotator 83 is elastically deformed. When the lifting driving clamping positioner 5 rises to the highest point, the distance between the rotation axis of the three-side frame 85 and the bottom surface of the arc track 3 is greater than the side length of the three-side frame 85. The three-side frame 85 can rotate, and the rollers on the side of the three-side frame 85 away from the driving pressure wheel 51 push the three-side frame 85 to rotate into the triangular area. The lifting driving clamping positioner 5 is reset and descended, and the three-side frame 85 reaches the reset height. The distance between the rotation axis of the three-side frame 85 and the bottom surface of the arc track 3 is less than the side length of the three-side frame 85, and the three-side frame 85 cannot rotate.

[0037] Advantages of the improvement: The rotation is used to clamp a single material each time and separate the single material from the subsequent accumulated materials. The spacing height required for rotation is used as a limiting condition, and a non-pressed structure is adopted, which will not affect the roller and can meet the limit requirements of slippery environments. The structure is simple and can be coupled with the lifting drive clamping positioner 5, reducing maintenance costs and use costs. In addition, the above structure does not require a power source to further simplify the structure and reduce the volume.

[0038] Supplementary explanation: The width of the discharge track 4 is greater than that of the arc track 3, and a blocking plate 21 is provided above the driving disc component 2. The blocking plate 21 does not contact the driving disc component 2, and the blocking plate 21 is flush with the side plate of the discharge track 4 close to the driving disc component 2. The blocking plate 21 can prevent the material from continuing to rotate through the driving disc component 2. Under the dual influence of the blocking effect of the blocking plate 21 and the blocking effect of the blocking baffle 71 on the roller, the roller will fall into the discharge track 4 to complete the collection.

[0039] The upper part of the lifting drive clamping positioner 5 is driven to move up and down by a driving member 6. The driving member 6 is arranged at the upper part without affecting the space below, thereby alleviating the space pressure of the processing area below.

[0040] One end of the arc track 3 away from the driving disc component 2 extends to the outside of the body of the driving disc component 2. During the processing, workers can feed materials through the arc track 3 away from the processing area 100, thereby improving safety.

[0041] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
