Description

Technical Field

[0001] The utility model belongs to the technical field of mechanical manufacturing, and particularly relates to a 90° 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. A 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 to prevent the slider from moving beyond the stroke on the slide rail, while restricting the running range of the translation rack, and further restricting the rotation range of the flipping gear, so as to prevent the components connected to the flipping gear from colliding with the support base 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 sufficient 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 90° 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 achieved by the following technical solutions:

[0005] A 90° flipping tooling includes a cylinder I, a base plate, a rack, a bracket A, a bracket B, a fixture base, and a gear; the cylinder I and the rack are longitudinally connected and installed on the upper surface of one end of the base plate, and the bracket A and the bracket B are vertically arranged on both sides of the upper surface of the base plate and are parallel to each other; the fixture base and the gear are fixedly connected and erected on the upper parts of the bracket A and the bracket B. It is characterized in that a limit fixing block is fixedly installed on the base plate, and the limit fixing block is located between the rack and the bracket B, and a buffer A is installed on the limit fixing block; when the cylinder I pushes the rack forward, the fixture base is flipped backward by 90° and abuts against the buffer A.

[0006] When Cylinder Ⅰ works, it drives the rack to move forward, driving the gear to rotate. When the gear rotates, it drives the fixture base fixedly connected to the gear to rotate. The fixture base rotates towards Cylinder Ⅰ. When the fixture base rotates 90°, it abuts against Buffer A. At this time, the supporting effect of Buffer A on the fixture base is direct and stable, and the limitation of Buffer A on the 90° rotation of the fixture base is also accurate. Then the staff can process the workpiece fixed on the fixture base without the shaking situation in the prior art.

[0007] In the above 90° flipping tooling, a limit bracket is fixedly installed on Bracket B, and Buffer B is installed on the limit bracket; when Cylinder Ⅰ pulls the rack to retract, the fixture base rotates forward 90° and abuts against Buffer B. That is, when Cylinder Ⅰ works, it pulls the rack to move backward, driving the gear to rotate in the reverse direction. Since the gear is fixedly connected to the fixture base, the fixture base rotates in the opposite direction of Cylinder Ⅰ, that is, the fixture base rotates 90° to the opposite side of Buffer A and abuts against Buffer B. Then the staff can process the workpiece fixed on the fixture base without the shaking situation in the prior art.

[0008] In the above 90° flipping tooling, it also includes Cylinder Pad Ⅰ, connecting block, bearing, transmission shaft, and guide rail. Cylinder Pad Ⅰ is installed at one end of the bottom plate, and Cylinder Ⅰ is fixedly installed on it; the guide rail is installed on the upper surface of the bottom plate, and the connecting block is slidably installed on the guide rail; the output end of Cylinder Ⅰ is connected to the connecting block; there are openings at the corresponding positions on the upper parts of Bracket A and Bracket B, and bearings are installed in the holes; the transmission shaft is fixedly connected to the fixture base and the gear. After passing through the fixture base and the gear, the protruding parts on both sides can be rotatably inserted into the bearings; the bottom of the gear meshes with the rack fixedly installed on the upper surface of the connecting block, and the gear drives the transmission shaft to rotate synchronously, thereby driving the fixture base and the workpiece fixed on it to rotate synchronously.

[0009] In the above 90° flipping tooling, a spacer A and a spacer B are also installed on the transmission shaft. The two ends of spacer A axially abut against the gear and the fixture base, the two ends of the fixture base axially abut against spacer A and spacer B, and the other end of spacer B axially approaches Bracket B. That is, the gear, spacer A, fixture base, and spacer B axially abut in sequence to achieve axial positioning.

[0010] In the above 90° flipping tooling, key A and key B fix the gear and the fixture base together from two directions, enabling the gear and the fixture base to rotate synchronously.

[0011] In the above 90° flipping tooling, the two ends of the transmission shafts on both sides of the fixture base respectively pass through the bearings on Bracket A and Bracket B. Retaining rings are installed outside the bearings, and covers are encapsulated outside the retaining rings.

[0012] In the above-mentioned 90° flipping tooling, a fixture base plate is also installed above the upper surface of the fixture seat. The fixture base plate is locked to the fixture seat with fasteners. A stop block and a clamping block are provided on the fixture base plate. The middle gap between the stop block and the clamping block can accommodate the workpiece. The cylinder II cushion block is fixedly installed on the bottom plate of the fixture seat, and the cylinder II is installed on the cylinder II cushion block. The cylinder II can push the clamping block from the outside of the clamping block, thereby clamping the workpiece between the clamping block and the stop block. Lock the fixture base plate to the upper surface of the fixture seat with fasteners, which is fixedly connected to the fixture seat. For different types of workpieces, the fixture base plate can be replaced to adapt to the dimensions of the new type of workpiece, so as to avoid the inconvenience of work and cost waste caused by replacing the fixture seat.

[0013] In the above-mentioned 90° flipping tooling, there are three bumps on the working surface of the clamping block, which is beneficial to enhancing the clamping force. Also based on the principle that three points form a plane, this is beneficial to clamping the workpiece and providing a fixed working platform for machining.

[0014] In the above-mentioned 90° flipping tooling, sensors are respectively installed on the buffer A and the buffer B. When the sensors sense the information that the process is over, they can transmit information to the background, causing the cylinder I to start and push the fixture seat to reset, realizing automatic flipping during the machining process, achieving simultaneous machining of both sides with one installation, and the workpiece is a finished product after one loading and unloading.

[0015] Compared with the prior art, the 90° flipping tooling has the following advantages: The fixture seat directly abuts against the buffer, ensuring that the flipping angle of the fixture seat is 90°; and with direct abutment, the flipping device will not shake, providing a stronger support for the fixture seat, and guaranteeing the accuracy and force of machining.

Specific implementation mode

[0025] The following are specific embodiments of the present invention. The technical solutions of the present invention are further described in conjunction with the accompanying drawings, but the present invention is not limited to these two embodiments.

[0026] Embodiment 1:

[0027] As Figures 1-6 shown, this 90° flipping tooling includes Cylinder I 1, Base plate 3, Rack 5, Bracket A 6, Bracket B 12, Fixture seat 14, and Gear 24; the Cylinder I 1 and the Rack 5 are longitudinally connected and installed on the upper surface of one end of the Base plate 3, and the Bracket A 6 and the Bracket B 12 are vertically arranged on both sides of the upper surface of the Base plate 3 and are parallel to each other; the Fixture seat 14 and the Gear 24 are fixedly connected and erected on the upper parts of the Bracket A 6 and the Bracket B 12. The key lies in that a Limit fixing block 8 is also fixedly installed on the Base plate 3, and the Limit fixing block 8 is located between the Rack 5 and the Bracket B 12, and a Buffer A 9 is installed on the Limit fixing block 8; when the Cylinder I 1 pushes the Rack 5 to move forward, the Fixture seat 14 is flipped backward by 90° and abuts against the Buffer A 9.

[0028] When the Cylinder I 1 works, it drives the Rack 5 to move forward, drives the Gear 24 to rotate, and when the Gear 24 rotates, it drives the Fixture seat 14 fixedly connected to the Gear 24 to rotate. The Fixture seat 14 rotates towards the Cylinder I 1 direction. When the Fixture seat 14 rotates 90°, it abuts against the Buffer A 9. At this time, the supporting effect of the Buffer A 9 on the Fixture seat 14 is direct and stable, and the limitation of the Buffer A 9 on the 90° rotation of the Fixture seat 14 is also accurate. Then the staff can process the Workpiece 19 fixed on the Fixture seat 14.

[0029] Moreover, a limit bracket 10 is fixedly installed on the bracket B12, and a buffer B11 is installed on the limit bracket 10; when the air cylinder I1 pulls the rack 5 backward, the fixture seat 14 flips forward 90° and then abuts against the buffer B11. That is, when the air cylinder I1 works, it pulls the rack 5 backward, drives the gear 24 to rotate in the reverse direction. Since the gear 24 is fixedly connected to the fixture seat 14, the fixture seat 14 rotates in the direction opposite to that of the air cylinder I1. After the fixture seat 14 flips 90° to the opposite side of the buffer A9, it abuts against the buffer B11. Then the staff can process the workpiece 19 fixed on the fixture seat 14.

[0030] Furthermore, the above 90° flipping tooling further includes an air cylinder spacer I2, a connecting block 4, a bearing 21, a transmission shaft 22, and a guide rail 13. The air cylinder spacer I2 is installed at one end of the bottom plate 3, and the air cylinder I1 is fixedly installed thereon; the guide rail 13 is installed on the upper surface of the bottom plate 3, and the connecting block 4 is slidably installed on the guide rail 13; the output end of the air cylinder I1 is connected to the connecting block 4; there are openings at the corresponding positions on the upper parts of the bracket A6 and the bracket B12, and the bearing 21 is installed in the holes; the transmission shaft 22 is fixedly connected to the fixture seat 14 and the gear 24. After passing through the fixture seat 14 and the gear 24, the two protruding parts on both sides can be rotatably inserted into the bearing 21; the bottom of the gear 24 meshes with the rack 5 fixedly installed on the upper surface of the connecting block 4, and the gear 24 drives the transmission shaft 22 to rotate synchronously, thereby driving the fixture seat 14 and the workpiece 19 fixed thereon to rotate synchronously.

[0031] Furthermore, a spacer A25 and a spacer B27 are installed on the transmission shaft 22. The two ends of the spacer A25 are axially abutted against the gear 24 and the fixture seat 14, the two ends of the fixture seat 14 are axially abutted against the spacer A25 and the spacer B27, and the other end of the spacer B27 is axially close to the bracket B12. That is, the gear 24, the spacer A25, the fixture seat 14, and the spacer B27 are axially abutted in sequence to achieve axial positioning.

[0032] Furthermore, the gear 24 and the fixture seat 14 are fixedly connected together by a flat key A23 and a flat key B26 from two directions, so that the gear 24 and the fixture seat 14 rotate synchronously.

[0033] Furthermore, a retaining ring 20 is installed on the outer side of the bearing 21 on the bracket A6 and the bracket B12, and a cover plate 7 is encapsulated on the outer side of the retaining ring 20.

[0034] Furthermore, a fixture base plate 15 is also installed above the upper surface of the fixture seat 14. The fixture base plate 15 is locked to the fixture seat 14 with fasteners. A stop block 17 and a clamping block 28 are arranged above the fixture base plate 15. The middle gap between the stop block 17 and the clamping block 28 can accommodate the workpiece 19. The cylinder II 18 can push the clamping block 28 from the outside of the clamping block 28, thereby clamping the workpiece 19 between the clamping block 28 and the stop block 17. The fixture base plate 15 is locked to the upper surface of the fixture seat 14 with fasteners and is fixedly connected to the fixture seat 14. For different types of workpieces 19, the fixture base plate 15 can be replaced to adapt to the size of the new type of workpiece 19, so as to avoid the inconvenience of work and cost waste caused by replacing the fixture seat 14.

[0035] Furthermore, there are three bumps on the working surface of the clamping block 28, which enhances the clamping effect. And based on the principle that three points form a plane, this is beneficial to clamping the workpiece 19 and enables the machining to have a fixed working platform.

[0036] Furthermore, sensors are respectively installed on the buffer A 9 and the buffer B 11. When the sensors sense the information that the process is over, they can transmit information to the background, causing the cylinder I 1 to start and push the fixture seat 14 to reset, realizing automatic flipping during the machining process, achieving simultaneous machining of both sides with one installation, and the workpiece is a finished product after one loading and unloading.

[0037] Embodiment 2:

[0038] As Figures 1-3 、 Figure 7 、 Figure 8 shown, this 90° flipping tooling includes a cylinder I 1, a base plate 3, a rack 5, a bracket A 6, a bracket B 12, a fixture seat 14, and a gear 24; the cylinder I 1 and the rack 5 are longitudinally connected and installed on the upper surface of one end of the base plate 3, and the bracket A 6 and the bracket B 12 are vertically arranged on both sides of the upper surface of the base plate 3 and are parallel to each other; the fixture seat 14 and the gear 24 are fixedly connected and erected on the upper parts of the bracket A 6 and the bracket B 12. The key lies in that a limit fixing block 8 is also fixedly installed on the base plate 3, and the limit fixing block 8 is located between the rack 5 and the bracket B 12, and a buffer A 9 is installed on the limit fixing block 8; when the cylinder I 1 pushes the rack 5 forward, the fixture seat 14 is flipped backward by 90° and abuts against the buffer A 9.

[0039] When the cylinder I 1 works, it drives the rack 5 to move forward, drives the gear 24 to rotate, and when the gear 24 rotates, it drives the fixture seat 14 fixedly connected to the gear 24 to rotate. The fixture seat 14 rotates towards the cylinder I 1 direction. When the fixture seat 14 rotates 90° and abuts against the buffer A 9, at this time, the supporting effect of the buffer A 9 on the fixture seat 14 is direct and stable, and the limitation of the buffer A 9 on the 90° rotation of the fixture seat 14 is also accurate. Then the staff can machine the workpiece 19 fixed on the fixture seat 14.

[0040] Moreover, a limit bracket 10 is fixedly installed on the bracket B12, and a buffer B11 is installed on the limit bracket 10; when the cylinder I 1 pulls the rack 5 backward, the fixture seat 14 flips forward by 90° and then abuts against the buffer B11. That is, when the cylinder I 1 works, it pulls the rack 5 to move backward, driving the gear 24 to rotate in the reverse direction. Since the gear 24 is fixedly connected to the fixture seat 14, the fixture seat 14 rotates in the direction opposite to that of the cylinder I 1. After the fixture seat 14 flips 90° to the opposite side of the buffer A9, it abuts against the buffer B11. Then, the worker can process the workpiece 19 fixed on the fixture seat 14.

[0041] Furthermore, the above 90° flipping tooling further includes a cylinder spacer I 2, a connecting block 4, a bearing 21, a transmission shaft 22, and a guide rail 13. The cylinder spacer I 2 is installed at one end of the bottom plate 3, and the cylinder I 1 is fixedly installed thereon; the guide rail 13 is installed on the upper surface of the bottom plate 3, and the connecting block 4 is slidably installed on the guide rail 13; the output end of the cylinder I 1 is connected to the connecting block 4; there are openings at the corresponding positions on the upper parts of the bracket A6 and the bracket B12, and the bearing 21 is installed in the holes; the transmission shaft 22 is fixedly connected to the fixture seat 14 and the gear 24. After passing through the fixture seat 14 and the gear 24, the two protruding parts on both sides can be rotatably inserted into the bearing 21; the bottom of the gear 24 meshes with the rack 5 fixedly installed on the upper surface of the connecting block 4, and the gear 24 drives the transmission shaft 22 to rotate synchronously, thereby driving the fixture seat 14 and the workpiece 19 fixed thereon to rotate synchronously.

[0042] Furthermore, a spacer A 25 and a spacer B 27 are installed on the transmission shaft 22. The two ends of the spacer A 25 axially abut against the gear 24 and the fixture seat 14, and the two ends of the fixture seat 14 axially abut against the spacer A 25 and the spacer B 27. One end of the spacer B 27 is provided with a retaining ring 31, and the retaining ring 31 is inserted into the bracket B12 and abuts against one end of the inner ring of the bearing; a locking nut 32 is also threadedly connected to the transmission shaft 22, and the locking nut 32 abuts against the other end of the inner ring of the bearing, thereby axially positioning the inner ring of the bearing on the transmission shaft 22. Thus, the gear 24, the spacer A 25, the fixture seat 14, and the spacer B 27 are axially arranged in sequence to achieve axial positioning.

[0043] Furthermore, the gear 24 and the fixture seat 14 are fixedly connected together from two directions by a flat key A 23 and a flat key B 26, so that the gear 24 and the fixture seat 14 rotate synchronously.

[0044] Furthermore, a retaining ring 20 is installed outside the bearing 21 on the bracket A6, and a cover plate 7 is encapsulated outside the retaining ring 20; a convex ring 29 is provided at the top end of the cover plate 7 when it is snapped into the bracket A6, and the convex ring 29 abuts against the outer end of the outer ring of the bearing for axial positioning of the outer ring of the bearing; the inner ring of the bearing abuts against the shoulder 30 to achieve axial positioning of the inner ring of the bearing.

[0045] Furthermore, a fixture bottom plate 15 is also installed above the upper surface of the fixture seat 14. The fixture bottom plate 15 is locked on the fixture seat 14 with fasteners. A stop block 17 and a clamping block 28 are arranged above the fixture bottom plate 15. The intermediate gap between the stop block 17 and the clamping block 28 can accommodate the workpiece 19. The cylinder II 18 can push the clamping block 28 from the outside of the clamping block 28, thereby clamping the workpiece 19 between the clamping block 28 and the stop block 17. The fixture bottom plate 15 is locked on the upper surface of the fixture seat 14 with fasteners and is fixedly connected to the fixture seat 14. For different types of workpieces 19, the fixture bottom plate 15 can be replaced to adapt to the size of the new type of workpiece 19, so as to avoid the inconvenience of work and cost waste caused by replacing the fixture seat 14.

[0046] Furthermore, there are three bumps on the working surface of the clamping block 28, which enhances the clamping effect. And based on the principle of three points forming a plane, this is beneficial to clamping the workpiece 19 and provides a fixed working platform for machining.

[0047] Furthermore, sensors are respectively installed on the buffer A 9 and the buffer B 11. When the sensors sense the information that the process is over, they can transmit information to the background, causing the cylinder I 1 to start and push the fixture seat 14 to reset, realizing automatic flipping during the machining process, achieving simultaneous machining of both sides with one installation, and one loading and unloading being the finished product.

[0048] In the above embodiments, the buffer A 9 and the buffer B 11 directly support the fixture seat 14, limiting the rotation angle of the fixture seat 14 to 90°.
