Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-5 A tooling for gear forgings includes a base 1. A vertical threaded rod 2 is fixedly installed at the center of the surface of the base 1. A rotating disk 3 is threadedly connected to the vertical threaded rod 2. A rotatable support disk 4 is provided on the top of the rotating disk 3, and a vertical hollow threaded rod 6 is fixedly installed on the top of the support disk 4. Both the vertical hollow threaded rod 6 and the support disk 4 have hollow through holes. The support disk 4 and the vertical hollow threaded rod 6 are sleeved on the vertical threaded rod 2. A clamping assembly 5 is provided on the outside of the vertical hollow threaded rod 6. When it is necessary to clamp and fix the gear, The through hole at the center of the gear is fitted onto the outside of the vertical hollow threaded rod 6. Then, the vertical hollow threaded rod 6 is used to press against the inner wall of the through hole of the gear, thus clamping the gear. At this time, the bottom of the gear is in contact with the surface of the support plate 4. This device can fix the gear from the center point, eliminating the damage to the outside of the gear when clamping and fixing the gear from the side. At the same time, the vertical position of the rotating plate 3 on the vertical threaded rod 2 can be adjusted by rotating the rotating plate 3, thereby changing the vertical height of the support plate 4 and the clamping assembly 5, which makes it easy to adjust the vertical height of the fixed gear.

[0026] Furthermore, the bottom of the support plate 4 is provided with an annular groove 7, and the rotating plate 3 is integrally formed with an annular protrusion 8 at the position corresponding to the annular groove 7. The annular protrusion 8 and the annular groove 7 are rotatably engaged together.

[0027] Furthermore, the clamping assembly 5 includes a threaded connection assembly and a hinge assembly. The threaded connection assembly is threadedly connected to the external thread on the vertical hollow threaded rod 6, and the threaded connection assembly is positioned above the hinge assembly.

[0028] Furthermore, the hinge assembly includes two hinge rods 10 and a hinge connecting block 11 hinged to the two hinge rods 10. A strip groove 9 is provided on the lower outer wall of the vertical hollow threaded rod 6. Two rectangular blocks are provided inside the strip groove 9. The bottom rectangular block is fixedly connected to the support plate 4, and the upper rectangular block is slidably engaged inside the strip groove 9 and connected to the threaded connecting assembly. The two rectangular blocks are respectively hinged to the free end of the corresponding hinge rod 10.

[0029] Furthermore, a rubber contact block 12 is fixedly installed on the side wall of the hinged connecting block 11 away from the vertical hollow threaded rod 6. When it is necessary to clamp and fix the gear, the threaded connecting assembly is rotated. When the threaded connecting assembly moves downward, it will squeeze the upper rectangular block. At this time, the distance between the two rectangular blocks becomes smaller, and then the distance between the two hinged rods 10 becomes smaller. At this time, the position of the hinged connecting block 11 is close to the inner wall of the gear through hole until the rubber contact block 12 is in contact with the inner wall of the gear through hole, thus completing the clamping of the gear. This device can be used to fix gears with different through hole sizes and has a high degree of flexibility.

[0030] Furthermore, the threaded connection assembly includes a threaded connection tube 16 and an annular connection block 13. The threaded connection tube 16 and the annular connection block 13 are rotatably connected together, and the bottom of the annular connection block 13 is fixedly connected to the rectangular locking block at the top. The upper end of the threaded connection tube 16 is threadedly connected to the vertical hollow threaded rod 6. When the threaded connection tube 16 is rotated, the threaded connection tube 16 moves up and down on the surface of the vertical hollow threaded rod 6, which in turn drives the annular connection block 13 to move up and down, causing the rectangular locking block at the top to slide up and down inside the strip groove 9.

[0031] Furthermore, the bottom of the threaded connecting pipe 16 is provided with an annular groove 14, and the top of the annular connecting block 13 is integrally formed with an annular protrusion 15 corresponding to the position of the annular groove 14. The annular protrusion 15 and the annular groove 14 are rotatably engaged together.

[0032] Structural Description:

[0033] Base 1

[0034] Function and role: As the basic support component of the entire tooling, it provides a stable mounting platform for other parts. It bears the weight of the entire tooling and the gear being processed, ensuring the overall stability of the tooling during gear operation.

[0035] Structural features: The shape is usually a flat plate with a certain thickness and area, so that it can be placed stably on the workbench. There is a specific mounting position at the center of its surface for fixing the vertical threaded rod 2. This mounting position must ensure that the vertical threaded rod 2 can be firmly connected to the base 1, and welding, threaded connection or other reliable connection methods are generally used.

[0036] Vertical threaded rod 2

[0037] Function and role: It is an important connecting and supporting component of the entire tooling. On the one hand, it provides a guide and support for the rotating disk 3 to move up and down, so that the rotating disk 3 can be precisely adjusted in vertical position through the threaded connection; on the other hand, it passes through the support disk 4 and the vertical hollow threaded rod 6, playing a positioning and auxiliary support role for these two components, ensuring their relative position stability during operation.

[0038] Structural Features: It is a vertical threaded rod with a continuous threaded structure on its outer surface. The precision and strength of the thread must ensure smooth vertical movement of the rotating disk 3 during frequent rotation and position adjustments, while also bearing the weight of the rotating disk 3 and the components above it without thread deformation or damage. Its length is designed according to actual needs, to meet the stroke range required for the vertical movement of the rotating disk 3, support disk 4, and clamping assembly 5 when machining gears of different sizes.

[0039] Rotary disk 3

[0040] Function and purpose: Primarily used to adjust the vertical height of the support plate 4 and the clamping assembly 5. Through its threaded connection with the vertical threaded rod 2, when the rotary disc 3 is rotated, it can move up and down along the vertical threaded rod 2, thereby synchronously changing the height of the connected support plate 4 and clamping assembly 5 to adapt to different processing requirements. Simultaneously, it also provides a rotatable connection base for the support plate 4, allowing the support plate 4 to rotate relative to it.

[0041] Structural features: Generally, it has a disc-shaped structure with a threaded hole at its center that matches the vertical threaded rod 2, through which a threaded connection is achieved. At the top, corresponding to the annular groove 7 at the bottom of the support disc 4, an annular protrusion 8 is integrally formed. This annular protrusion 8 forms a rotating engagement structure with the annular groove 7 of the support disc 4, ensuring that the support disc 4 can rotate smoothly on the rotating disc 3 while preventing the support disc 4 from detaching from the rotating disc 3 during vertical movement.

[0042] Support plate 4

[0043] Functions and uses: First, it provides a bottom support surface for the gear when clamping and fixing it, ensuring that the gear remains horizontal and stable during clamping. Second, it serves as the mounting base for the vertical hollow threaded rod 6, firmly fixing the vertical hollow threaded rod 6 to its top, and together with the vertical hollow threaded rod 6, it is sleeved on the vertical threaded rod 2, ensuring the integrity and stability of the entire tooling structure. Third, through the rotating engagement structure between the annular groove 7 at its bottom and the annular protrusion 8 of the rotating disk 3, it achieves a rotatable connection with the rotating disk 3, so that when the rotating disk 3 moves up and down, the support disk 4 can move up and down synchronously with it, and can also rotate freely in its own plane.

[0044] Structural Features: Typically a circular, disc-shaped structure, its top center is reliably fixed to the vertical hollow threaded rod 6 using welding, threaded connection, or other methods. An annular groove 7 is provided at the bottom; the size and shape of the annular groove 7 must precisely match the annular protrusion 8 of the rotating disk 3 to achieve a good rotational engagement effect. Its thickness is designed according to actual needs, and must be able to withstand the weight of the gears and the pressure that may be generated during processing without deformation.

[0045] Clamping component 5

[0046] Function and role: It is responsible for the actual clamping and fixing of gears. It can adaptively adjust according to the different sizes of the gear through holes to ensure that gears of different specifications can be firmly and stably clamped to meet the needs of subsequent processing.

[0047] Structural features: It consists of two parts: a threaded connection assembly and a hinged assembly, which work together in coordination.

[0048] The threaded connection assembly mainly includes a threaded connecting pipe 16 and an annular connecting block 13. The threaded connecting pipe 16 is connected to the vertical hollow threaded rod 6 via threads. When the threaded connecting pipe 16 is rotated, it can move up and down on the surface of the vertical hollow threaded rod 6, thereby driving the annular connecting block 13 to move up and down. The annular connecting block 13 and the threaded connecting pipe 16 are rotatably engaged through an annular groove 14 and an annular protrusion 15, ensuring that they can rotate relative to each other while maintaining a connection. The bottom of the annular connecting block 13 is fixedly connected to a rectangular locking block at its upper end, establishing a connection with the hinge assembly through the upper rectangular locking block.

[0049] The hinge assembly includes two hinge rods 10 and a hinge connecting block 11 hinged to the two hinge rods 10. A strip groove 9 is formed on the lower outer wall of the vertical hollow threaded rod 6. Two rectangular locking blocks are disposed within the strip groove 9. The bottom rectangular locking block is fixedly connected to the support plate 4, while the upper rectangular locking block is slidably engaged inside the strip groove 9 and fixedly connected to the threaded connection assembly, specifically to the annular connecting block 13. The two rectangular locking blocks are respectively hinged to the free ends of the corresponding hinge rods 10. When the threaded connection assembly moves the upper rectangular locking block, the distance between the two hinge rods 10 changes, thereby driving the hinge connecting block 11 to move closer to or further away from the inner wall of the gear's through hole, ultimately achieving the clamping or releasing operation of the gear.

[0050] Vertical hollow threaded rod 6

[0051] Functions and uses: First, it serves as a mounting support component for clamping assembly 5, providing mounting positions and support for threaded connection assembly and hinge assembly; second, when clamping and fixing gears, the central through hole of the gear is fitted on its outer side, and through the action of clamping assembly 5, it can be tightly fitted with the inner wall of the through hole of the gear, thereby achieving clamping and fixing of the gear from the center point and avoiding damage to the outer side of the gear caused by clamping from the side.

[0052] Structural features: It is a hollow threaded rod, with its hollow interior forming a through channel for easy installation with other components. Its outer surface has a threaded structure for threaded connection with the threaded connecting pipe 16. A strip groove 9 is provided on the lower outer wall to provide a sliding and mounting position for the rectangular locking block in the hinge assembly.

[0053] Annular groove 7

[0054] Function and purpose: It is located at the bottom of the support plate 4 and forms a rotating engagement structure with the annular protrusion 8 of the rotating plate 3, so that the support plate 4 can rotate smoothly on the rotating plate 3. At the same time, it ensures the connection between the support plate 4 and the rotating plate 3 when the rotating plate 3 moves up and down, and prevents the support plate 4 from separating from the rotating plate 3.

[0055] Structural features: It is an annular groove structure surrounding the center of the bottom of the support plate 4. Its size and shape must be precisely matched with the annular protrusion 8 of the rotating plate 3, including the depth, width and circumferential shape of the groove, in order to achieve a good rotation and locking effect.

[0056] Annular protrusion - 8

[0057] Function and role: The one-piece molded top of the rotating disk 3 corresponds to the position of the bottom annular groove 7 of the support disk 4, forming a rotating snap-fit ​​structure with the annular groove 7, providing a rotatable connection base for the support disk 4, so that the support disk 4 can rotate smoothly on the rotating disk 3. At the same time, when the rotating disk 3 moves up and down, it ensures the connection between the support disk 4 and the rotating disk 3, and prevents the support disk 4 from detaching from the rotating disk 3.

[0058] Function and purpose: It is an annular protrusion structure that surrounds the center of the top of the rotating disk 3, corresponding to the position of the annular groove 7. Its size and shape must be precisely matched with the annular groove 7 of the support disk 4, including the height, width and circumferential shape of the protrusion, so as to achieve a good rotation and locking effect.

[0059] Slot 9

[0060] Function and role: Located on the lower outer wall of the vertical hollow threaded rod 6, it provides sliding and mounting positions for the two rectangular blocks in the hinge assembly. When the threaded connection assembly moves the upper rectangular block within the slot 9, the hinge relationship between the two rectangular blocks and the hinge rod 10 changes the distance between the two hinge rods 10, thereby driving the hinge connecting block 11 to move closer to or away from the inner wall of the gear's through hole, ultimately achieving the clamping or releasing operation of the gear.

[0061] Structural features: It is a strip-shaped groove structure longitudinally opened along the outer wall of the lower end of the vertical hollow threaded rod 6. Its length, width and depth need to be designed according to the size of the rectangular locking block and the actual operation requirements, so as to ensure that the rectangular locking block can slide smoothly in it without jamming or detachment.

[0062] Hinge rod 10

[0063] Function and role: It is an important component of the hinge assembly, with its two ends hinged to the corresponding rectangular locking blocks and hinge connecting blocks 11, respectively. When the distance between the rectangular locking blocks changes, the distance between the two hinge rods 10 can also change through the hinge relationship, thereby driving the hinge connecting blocks 11 to move closer to or away from the inner wall of the gear's through hole, ultimately realizing the clamping or releasing operation of the gear.

[0064] Structural features: Generally, it is a slender rod-shaped structure with specific hinge structures at both ends to facilitate smooth hinged connection with rectangular blocks and hinged connecting blocks 11. Its length is designed according to actual needs, so as to effectively move the hinged connecting blocks 11 to a suitable position to achieve the clamping or releasing operation of the gear when the spacing of the rectangular blocks changes.

[0065] Hinged connecting block 11

[0066] Function and role: It is hinged to two hinge rods 10. When the distance between the hinge rods 10 changes, its position will change accordingly, so that the rubber bonding block 12 fixedly installed on one side wall can fit against the inner wall of the gear through hole, thereby realizing the clamping operation of the gear.

[0067] Structural features: Generally a block structure, with hinged connection positions on both sides for connecting to the hinge rod 10, and a rubber bonding block 12 fixedly installed on one side wall. Its size is designed according to actual needs, so that when the spacing of the hinge rod 10 changes, the rubber bonding block 12 can be effectively moved to a suitable position to achieve the clamping or releasing operation of the gear.

[0068] Rubber bonding block 12

[0069] Function and purpose: It is fixedly installed on one side wall of the hinged connecting block 11. When the hinged connecting block 11 moves to the appropriate position as the distance between the hinge rods 10 changes, the rubber bonding block 12 can fit against the inner wall of the gear through hole, which plays a role in buffering and increasing friction. It can protect the inner wall of the gear through hole from being scratched and ensure that the gear is clamped more firmly.

[0070] Structural features: It is generally a block structure made of rubber. Its shape is usually designed according to the shape of the inner wall of the gear through hole. It is generally circular or similar to the shape of the inner wall of the through hole to ensure a good fit with the inner wall of the gear through hole.

[0071] Annular connecting block 13

[0072] Function and role: It is an important component of the threaded connection assembly. On the one hand, it is rotatably engaged with the threaded connection pipe 16 through the annular groove 14 and the annular protrusion 15, ensuring that the two can rotate relative to each other while maintaining the connection relationship. On the other hand, its bottom is fixedly connected to the rectangular locking block at the top, and it establishes a connection with the hinge assembly through the rectangular locking block at the top. When the threaded connection pipe 16 moves, it can drive the rectangular locking block at the top to move, thereby affecting the working state of the hinge assembly.

[0073] Structural features: Generally a block structure, with an annular protrusion 15 integrally formed at the top corresponding to the position of the annular groove 14, and the bottom is fixedly connected to the rectangular locking block at the top. Its dimensions are designed according to actual needs, so that when the threaded connecting pipe 16 moves, it can effectively drive the rectangular locking block at the top to move, thereby affecting the working state of the hinge assembly.

[0074] Annular groove 2.14

[0075] Function and role: It is opened at the bottom of the threaded connecting pipe 16 and forms a rotating locking structure with the annular protrusion 15 of the annular connecting block 13, so that the annular connecting block 13 can rotate smoothly on the threaded connecting pipe 16, while ensuring that the two can rotate relative to each other and maintain a connection relationship, so that when the threaded connecting pipe 16 moves, the annular connecting block 13 can move with it and drive the rectangular locking block at the upper end to move.

[0076] Structural features: It is an annular groove structure that surrounds the center of the bottom of the threaded connecting pipe 16. Its size and shape must be precisely matched with the annular protrusion 15 of the annular connecting block 13, including the depth, width and circumferential shape of the groove, so as to achieve a good rotation and snap-fit ​​effect.

[0077] Annular protrusion 215

[0078] Function and role: The ring connecting block 13 is integrally formed at the position of the annular groove 14 on the top, forming a rotating snap-fit ​​structure with the annular groove 14. This provides the ring connecting block 13 with a rotatable connection base on the threaded connecting pipe 16, allowing the ring connecting block 13 to rotate smoothly on the threaded connecting pipe 16. At the same time, it ensures that the two can rotate relative to each other while maintaining a connection relationship, so that when the threaded connecting pipe 16 moves, the ring connecting block 13 can move with it and drive the rectangular snap-fit ​​block at the top to move.

[0079] Structural features: It is an annular protrusion structure that surrounds the top center of the annular connecting block 13, corresponding to the position of the annular groove 14. Its size and shape must be precisely matched with the annular groove 14 of the threaded connecting pipe 16, including the height, width and circumferential shape of the protrusion, so as to achieve a good rotation and snap-fit ​​effect.

[0080] Threaded connecting pipe 16

[0081] Function and role: It is an important component of the threaded connection assembly. It is connected to the vertical hollow threaded rod 6 by threads. When the threaded connection tube 16 is rotated, it can move up and down on the surface of the vertical hollow threaded rod 6, thereby driving the annular connection block 13 to move up and down. This causes the rectangular locking block at the upper end to slide up and down inside the strip groove 9, ultimately affecting the working state of the hinge assembly and realizing the clamping or releasing operation of the gear.

[0082] Structural Features: It is a tubular structure with internal threads that match the vertical hollow threaded rod 6, enabling threaded connection between them. An annular groove 14 is formed at its bottom, creating a rotating engagement structure with the annular protrusion 15 of the annular connecting block 13, ensuring both relative rotation and connection. Its length is designed according to actual needs, ensuring effective movement of the annular connecting block 13 during rotation, thereby affecting the working state of the hinge assembly.

[0083] Working principle: The threaded connecting pipe 16 is rotated, and the threaded connecting pipe 16 moves up and down on the surface of the vertical hollow threaded rod 6. Then, it drives the annular connecting block 13 to move up and down, and drives the rectangular locking block at the upper end to slide up and down inside the strip groove 9. At this time, the distance between the two rectangular locking blocks becomes smaller, and then the distance between the two hinge rods 10 becomes smaller. At this time, the position of the hinge connecting block 11 is close to the inner wall of the gear through hole, until the rubber bonding block 12 is in contact with the inner wall of the gear through hole, thus completing the clamping of the gear. At the same time, the vertical position of the rotating disk 3 on the vertical threaded rod 2 can be adjusted by rotating the rotating disk 3, thereby changing the vertical height of the support disk 4 and the clamping assembly 5, which makes it easy to adjust the vertical height of the fixed gear.

[0084] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
