Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a 180° flipping tooling. Background Art

[0002] Tooling is a commonly used tool and equipment in mechanical manufacturing and processing, and is an auxiliary tool in the mechanical manufacturing and processing process. Its main functions are to clamp workpieces, position, and assist in cutting and drilling. Compared with manual operation, using tooling can greatly improve the accuracy and efficiency of machining. The flipping tooling is a tool and equipment that facilitates rotating workpieces in the same tooling for multi-sided machining. Whether the fixture base or the flipping frame in the flipping tooling can be accurately limited is the key technology for the smooth progress of machining. In the prior art, as recorded in CN220299613U, by setting limit baffles at both ends of the slide rail, the movement of the slider on the slide rail is prevented from exceeding the stroke, and at the same time, the running range of the translation rack is restricted, and then the rotation range of the flipping gear is restricted, so as to prevent the components connected to the flipping gear from colliding with the support bottom plate. Although the limit baffles restrict the running range of the translation rack, due to the gap between the meshing of the translation rack and the gear, the meshing force is not enough to fix the flipping device in an accurate position, resulting in the shaking of the flipping device and reducing the accuracy and efficiency of machining on the flipping device. Summary of the Invention

[0003] Aiming at the defects existing in the prior art, the utility model provides a 180° flipping tooling to solve the problems of unstable positioning and shaking of the flipping device, resulting in poor machining accuracy and low efficiency.

[0004] The purpose of the utility model can be realized by the following technical solutions:

[0005] A 180° flipping tooling includes a cylinder, a bottom plate A, a bracket A, a bracket B, a bottom plate B, a guide rail, a rack A, a rack B, a rack C, a gear A, a gear B and a fixture base; a cylinder is installed at one end of the bottom plate A, and the bracket A and the bracket B are vertically and symmetrically arranged on both sides. After the fixture base and the gear B are fixedly connected, they are erected on the upper parts of the bracket A and the bracket B; the guide rail and the rack A are fixedly installed on the bottom plate A in sequence between the bracket A and the bracket B, and the bottom plate B is slidably installed on the guide rail; a rack C is installed on the upper surface of the bottom plate B, and a rack B is installed on the back; the top of the gear A meshes with the rack B, and the bottom meshes with the rack A; the bottom of the gear B meshes with the rack C, and it is characterized in that a limit bracket A is fixedly installed on the inner side of the bracket B, and a buffer A is installed on the limit bracket A; when the cylinder drives the gear A to rotate clockwise, through the conduction of the rack B, the bottom plate B and the rack C, the gear B is caused to rotate counterclockwise, and the fixture base rotates counterclockwise by 180° and then abuts against the buffer A.

[0006] When the cylinder works, it drives the gear A to rotate. FromFigure 4 Viewed from the front view angle of this 180° flipping tooling, it rotates clockwise. Since rack A is fixed on base plate A and does not move, gear A and rack B move forward simultaneously. Also, since rack B is fixed on the lower surface of base plate B, base plate B also moves forward. Further, since rack C is fixed on the upper surface of base plate B, the movement of base plate B drives rack C to move forward together. Furthermore, the forward movement of rack C causes gear B to rotate counterclockwise. Since gear B is fixedly connected to the fixture base, the fixture base undergoes a counterclockwise flip. From Figure 4 Viewed from the front view angle of this 180° flipping tooling, after the fixture base has flipped counterclockwise by 180°, it abuts against buffer A. At this time, the operator can machine the workpiece fixed on the fixture base.

[0007] In the above-mentioned 180° flipping tooling, a limit support B is detachably installed on the end face of support B far from the cylinder, and a buffer B is installed on the limit support B. When the cylinder operates, it drives gear A to rotate counterclockwise. Through the transmission of rack B, base plate B, and rack C, it causes gear B to rotate clockwise. After the fixture base has flipped clockwise by 90°, it abuts against buffer B. At this time, the operator can machine the workpiece fixed on the fixture base. This is a 90° flipping tooling. When the 180° flipping tooling is needed, the limit support B and buffer B can be removed.

[0008] In the above-mentioned 180° flipping tooling, it also includes a cylinder cushion block, a guide rail support block, a cylinder connection block, a gear connection block, and a rack fixing block; the cylinder is fixedly installed on the cylinder cushion block, and the cylinder cushion block is fixedly installed at one end of base plate A; on the upper surface of the said base plate A, a guide rail support block, rack A, and a rack fixing block are successively installed in parallel between support A and support B; a guide rail is laid on the guide rail support block, and base plate B is slidably installed on the guide rail; the output end of the cylinder is connected to the cylinder connection block, the cylinder connection block is connected to the gear connection block, and the gear connection block receives the torque force transmitted by the cylinder connection block to drive gear A to rotate; there are openings at the corresponding positions of the upper parts of support A and support B, bearings are installed in the holes, and the two ends of the transmission shaft extending through gear B and the fixture base can be rotatably inserted into the bearings respectively; the said transmission shaft is fixedly installed with gear B and rotates with gear B.

[0009] In the above-mentioned 180° flipping tooling, a spacer A and a spacer B are installed on the transmission shaft. The two ends of the fixture base axially abut against the spacer A and the spacer B respectively. The other end of the spacer A axially abuts against gear B, and the other end of the spacer B axially approaches support B. Through this technical solution, components such as support A, gear B, spacer A, fixture base, spacer B, and support A form axial fixation.

[0010] In the above-mentioned 90° flipping tooling, gear B and the fixture base are fixedly connected together with flat key A and flat key B, so that gear B and the fixture base rotate synchronously.

[0011] In the above 90° flipping tooling, retaining rings are installed on the outer sides of the bearings on support A and support B, and cover plates are encapsulated on the outer sides of the retaining rings.

[0012] In the above 90° flipping tooling, a fixture bottom plate is installed above the upper surface of the fixture seat, and the fixture bottom plate is locked to the fixture seat with fasteners. A clamping device is arranged above the fixture bottom plate for clamping the workpiece. By installing the fixture bottom plate above the upper surface of the fixture seat, the workpiece is fixed on the fixture bottom plate instead of directly on the fixture seat. In this way, for different types of workpieces, the size of the new type of workpiece can be adapted by replacing the fixture bottom plate, avoiding the inconvenience of work and cost waste caused by replacing the fixture seat.

[0013] In the above 90° flipping tooling, sensors are respectively installed on buffer A and buffer B. When the sensors sense the information that the process is over, they can transmit information to the background, causing the air cylinder to start and driving the fixture seat to reset, realizing automatic flipping during the processing, achieving simultaneous machining of both sides with one installation, and the workpiece is a finished product after one loading and unloading.

[0014] Compared with the prior art, the present 180° flipping tooling has the following advantages: The fixture seat directly abuts against the buffer, providing a stronger support for the fixture seat, ensuring that the flipping angle of the fixture seat is 180°, and preventing the situation of the fixture seat shaking, thus guaranteeing the accuracy and force of machining.

DETAILED DESCRIPTION

[0024] The following are specific embodiments of the present invention, and the technical solution of the present invention is further described in conjunction with the accompanying drawings, but the present invention is not limited to these two embodiments.

[0025] Embodiment 1:

[0026] like Figures 1-6 As shown, the 180° flip tooling includes a cylinder 1, a base plate A3, a bracket A4, a bracket B5, a base plate B17, a guide rail 29, a rack A9, a rack B14, a rack C15, a gear A16, a gear B21 and a fixture seat 26; the cylinder 1 is installed at one end of the base plate A3, and brackets A4 and brackets B5 are vertically and balancedly arranged on both sides, and the fixture seat 26 and the gear B21 are fixedly connected and erected on the upper part of the bracket A4 and the bracket B5; the guide rail 29 and the rack A9 are fixedly installed on the base plate A3 between the bracket A4 and the bracket B5 in turn, and the base plate B17 is slidably installed on the guide rail 29; the rack C15 is installed on the upper surface of the base plate B17, and the rack B14 is installed on the back; the top of the gear A16 is meshed with the rack B14, and the bottom is meshed with the rack A9; the bottom of the gear B21 is meshed with the rack C15. The key is to fix the limit bracket A11 on the inner side of the bracket B5, and install the buffer A12 on the limit bracket A11; the cylinder 1 drives the gear A16 to rotate clockwise, which is transmitted through the rack B14, the bottom plate B17, and the rack C15, causing the gear B21 to rotate counterclockwise, and the clamp seat 26 then flips 180° counterclockwise and rests on the buffer A12.

[0027] When the cylinder is working, the drive gear A16 rotates, Figure 4Viewed from the front view angle of this 180° flipping tooling, it rotates clockwise. Since the rack A9 is fixed on the bottom plate A3 without moving, the gear A16 and the rack B14 move forward synchronously. Also, since the rack B14 is fixed on the lower surface of the bottom plate B17, the bottom plate B17 also moves forward. Furthermore, since the rack C15 is fixed on the upper surface of the bottom plate B17, the movement of the bottom plate B17 drives the rack C15 to move forward together. Further, the forward movement of the rack C15 causes the gear B21 to rotate counterclockwise; since the gear B21 and the fixture base 26 are fixedly connected, the fixture base 26 undergoes a counterclockwise flip. From Figure 4 Viewed from the front view angle of this 180° flipping tooling, after the fixture base 26 has been flipped counterclockwise by 180°, it abuts against the buffer A12. At this time, the staff can process the workpiece 28 fixed on the fixture base 26.

[0028] Furthermore, a limit support B30 is detachably installed on the end face of the support B5 far from the cylinder 1, and a buffer B31 is installed on the limit support B30. The cylinder 1 drives the gear A16 to rotate counterclockwise. Through the transmission of the rack B14, the bottom plate B17, and the rack C15, the gear B21 rotates clockwise. After the fixture base 26 has been flipped clockwise by 90°, it abuts against the buffer B31. At this time, the staff can process the workpiece 28 fixed on the fixture base 26. This is a 90° flipping tooling. When the 180° flipping tooling is needed, the limit support B30 and the buffer B31 can be removed.

[0029] Furthermore, this embodiment also includes a cylinder spacer 2, a guide rail support block 6, a cylinder connection block 7, a gear connection block 8, and a rack fixing block 10; the cylinder 1 is fixedly installed on the cylinder spacer 2, and the cylinder spacer 2 is fixedly installed at one end of the bottom plate A3; on the upper surface of the bottom plate A3, the guide rail support block 6, the rack A9, and the rack fixing block 10 are sequentially and juxtaposed between the support A4 and the support B5; a guide rail 29 is laid on the guide rail support block 6, and the bottom plate B17 is slidably installed on the guide rail 29; the output end of the cylinder 1 is connected to the cylinder connection block 7, the cylinder connection block 7 is connected to the gear connection block 8, and the gear connection block 8 receives the torque force transmitted by the cylinder connection block 7 and drives the gear A16 to rotate; there are openings at the corresponding positions of the upper parts of the support A4 and the support B5, bearings 19 are installed in the holes, and the two ends of the transmission shaft 20 extending through the gear B21 and the fixture base 26 can be rotatably inserted into the bearings 19 respectively; the transmission shaft 20 is fixedly installed with the gear B21 and rotates with the gear B21.

[0030] Furthermore, a spacer A23 and a spacer B25 are installed on the transmission shaft 20. Both ends of the fixture seat 26 axially abut against the spacer A23 and the spacer B25. The other end of the spacer A23 axially abuts against the gear B21, and the other end of the spacer B25 axially approaches the bracket B5. Through this technical solution, components such as the bracket A4, the gear B21, the spacer A23, the fixture seat 26, the spacer B25, and the bracket A4 form axial fixation.

[0031] Furthermore, the gear B21 and the fixture seat 26 are fixedly connected together with a flat key A22 and a flat key B24, so that the gear B21 and the fixture seat 26 rotate synchronously.

[0032] Furthermore, a retaining ring 18 is installed on the outer side of the bearing 19 on the bracket A4 and the bracket B5, and a cover plate 13 is encapsulated on the outer side of the retaining ring 18.

[0033] Furthermore, a fixture base plate 27 is installed above the upper surface of the fixture seat 26, and the fixture base plate 27 is locked to the fixture seat 26 with fasteners. A clamping device is provided above the fixture base plate 27 for clamping the workpiece 28. By installing the fixture base plate 27 above the upper surface of the fixture seat 26, the workpiece 28 is fixed on the fixture base plate 27 instead of directly on the fixture seat 26. In this way, for different types of workpieces, the fixture base plate 27 can be replaced to adapt to the dimensions of the new type of workpiece 28, avoiding the inconvenience of work and cost waste caused by replacing the fixture seat 26.

[0034] Furthermore, sensors are respectively installed on the buffer A12 and the buffer B31.

[0035] Embodiment 2:

[0036] As Figures 1-3 、 Figure 7 、 Figure 8As shown in the figure, this 180° flipping tooling includes a cylinder 1, a bottom plate A3, a bracket A4, a bracket B5, a bottom plate B17, a guide rail 29, a rack A9, a rack B14, a rack C15, a gear A16, a gear B21, and a fixture seat 26. The cylinder 1 is installed at one end of the bottom plate A3, and the bracket A4 and the bracket B5 are vertically and symmetrically arranged on both sides. After the fixture seat 26 and the gear B21 are fixedly connected, they are erected on the upper parts of the bracket A4 and the bracket B5. The guide rail 29 and the rack A9 are successively fixedly installed on the bottom plate A3 between the bracket A4 and the bracket B5, and the bottom plate B17 is slidably installed on the guide rail 29. The rack C15 is installed on the upper surface of the bottom plate B17, and the rack B14 is installed on the back surface. The top of the gear A16 meshes with the rack B14, and the bottom meshes with the rack A9. The bottom of the gear B21 meshes with the rack C15. The key lies in that a limit bracket A11 is fixedly installed on the inner side of the bracket B5, and a buffer A12 is installed on the limit bracket A11. The cylinder 1 drives the gear A16 to rotate clockwise. Through the transmission of the rack B14, the bottom plate B17, and the rack C15, the gear B21 is caused to rotate counterclockwise, and the fixture seat 26 rotates counterclockwise by 180° and then abuts against the buffer A12.

[0037] When the cylinder works, it drives the gear A16 to rotate. From Figure 4 From the front view angle of this 180° flipping tooling, it rotates clockwise. Since the rack A9 is fixed on the bottom plate A3 and does not move, the gear A16 and the rack B14 move forward synchronously. Also, since the rack B14 is fixed on the lower surface of the bottom plate B17, the bottom plate B17 also moves forward. Further, since the rack C15 is fixed on the upper surface of the bottom plate B17, the movement of the bottom plate B17 drives the rack C15 to move forward together. Furthermore, the forward movement of the rack C15 causes the gear B21 to rotate counterclockwise. Since the gear B21 and the fixture seat 26 are fixedly connected, the fixture seat 26 rotates counterclockwise. From Figure 4 From the front view angle of this 180° flipping tooling, the fixture seat 26 rotates counterclockwise by 180° and then abuts against the buffer A12. At this time, the staff can process the workpiece 28 fixed on the fixture seat 26.

[0038] Furthermore, a limit bracket B30 is detachably installed on the end face of the bracket B5 far from the cylinder 1, and a buffer B31 is installed on the limit bracket B30. The cylinder 1 drives the gear A16 to rotate counterclockwise. Through the transmission of the rack B14, the bottom plate B17, and the rack C15, the gear B21 is caused to rotate clockwise, and the fixture seat 26 rotates clockwise by 90° and then abuts against the buffer B31. At this time, the staff can process the workpiece 28 fixed on the fixture seat 26. This is a 90° flipping tooling. When the 180° flipping tooling is needed, the limit bracket B30 and the buffer B31 can be removed.

[0039] Furthermore, this embodiment further includes a cylinder spacer block 2, a guide rail support block 6, a cylinder connection block 7, a gear connection block 8, and a rack fixing block 10. The cylinder 1 is fixedly installed on the cylinder spacer block 2, and the cylinder spacer block 2 is fixedly installed at one end of the bottom plate A3. On the upper surface of the bottom plate A3, the guide rail support block 6, the rack A9, and the rack fixing block 10 are sequentially and juxtaposedly installed between the support A4 and the support B5. A guide rail 29 is laid on the guide rail support block 6, and the bottom plate B17 is slidably installed on the guide rail 29. The output end of the cylinder 1 is connected to the cylinder connection block 7, the cylinder connection block 7 is connected to the gear connection block 8, and the gear connection block 8 receives the torque force transmitted by the cylinder connection block 7 to drive the gear A16 to rotate. There are openings at the corresponding positions of the upper parts of the support A4 and the support B5, and bearings 19 are installed in the holes. The two ends of the transmission shaft 20 that extend out after passing through the gear B21 and the fixture seat 26 are respectively rotatably inserted into the bearings 19. The transmission shaft 20 is fixedly installed with the gear B21 and rotates with the gear B21.

[0040] Furthermore, a spacer sleeve A23 and a spacer sleeve B25 are installed on the transmission shaft 20, and the two ends of the fixture seat 26 are axially abutted against the spacer sleeve A23 and the spacer sleeve B25. The other end of the spacer sleeve A23 is axially abutted against the gear B21, and a retaining ring 34 is provided at the other end of the spacer sleeve B25. The retaining ring 34 is inserted into the support B5 and abuts against one end of the inner ring of the bearing. A locking nut 35 is also threadedly connected to the transmission shaft 20, and the locking nut 35 abuts against the other end of the inner ring of the bearing, so that the inner ring of the bearing is axially positioned on the transmission shaft 20. Thus, the gear B21, the spacer sleeve A23, the fixture seat 26, and the spacer sleeve B25 are sequentially arranged axially to achieve axial positioning.

[0041] Furthermore, the gear B21 and the fixture seat 26 are fixedly connected together with a flat key A22 and a flat key B24, so that the gear B21 and the fixture seat 26 rotate synchronously.

[0042] Furthermore, a retaining ring 18 is installed outside the bearing 19 on the support A4, and a cover plate 13 is encapsulated outside the retaining ring 18. A convex ring 32 is provided at the top end of the support A4 where the cover plate 13 is snapped in, and the convex ring 32 abuts against the outer end of the outer ring of the bearing for axially positioning the outer ring of the bearing. The inner ring of the bearing abuts against the shoulder 33 to achieve axial positioning of the inner ring of the bearing.

[0043] Furthermore, a fixture bottom plate 27 is installed above the upper surface of the fixture seat 26, and the fixture bottom plate 27 is locked to the fixture seat 26 with fasteners. A clamping device is provided above the fixture bottom plate 27 for clamping the workpiece 28. By installing the fixture bottom plate 27 above the upper surface of the fixture seat 26, the workpiece 28 is fixed on the fixture bottom plate 27 instead of directly on the fixture seat 26. In this way, for different types of workpieces, the fixture bottom plate 27 can be replaced to adapt to the dimensions of the new type of workpiece 28, avoiding the inconvenience of work and cost waste caused by replacing the fixture seat 26.

[0044] Furthermore, sensors are respectively installed on buffer A12 and buffer B31. When the sensors sense the information indicating the end of the process, they can transmit information to the background, causing cylinder 1 to start and driving fixture seat 26 to reset, achieving automatic flipping during the machining process, enabling simultaneous machining of both sides in one installation, and making the workpiece a finished product after one loading and unloading.

[0045] In the above two embodiments, buffer A12 and buffer B31 directly support fixture seat 26, limiting the rotation angle of fixture seat 26 to 180° or 90°. The support of buffer A12 and buffer B31 for fixture seat 26 is firm and strong, and fixture seat 26 will not shake, thus improving the machining accuracy and efficiency.

Those skilled in the art to which the present invention pertains can make various modifications or supplements to the described specific embodiments or use similar ways to substitute, but will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
