Description

Technical Field

[0001] This utility model relates to the field of joint shaping technology, specifically a joint inner hole shaping tool. Background Technology

[0002] The microchannel tooth pitch of the liquid-cooled plate is on the order of 0.1mm (compared to millimeters for air-cooled plates), requiring more precise design and manufacturing to consider flow channels and flow resistance. The water-cooled plate and mounting plate are integrated, ensuring no leakage. Each liquid-cooled server has an inlet and outlet water pipe, along with connectors. Using metal or ceramic powder as the main raw material, after injection molding, degreasing and sintering, the core components of the liquid-cooled connector are produced, resulting in low-cost, highly consistent, reliable, stable, high-density, and highly airtight components. During production, the inner hole is highly susceptible to deformation due to external impact or stress release during heat treatment, potentially becoming elliptical or polygonal. This necessitates reshaping operations, such as stamping the inner hole of the connector.

[0003] Traditional processing methods employ hydraulic presses with shaping rods corresponding to the inner hole of the joint. The fixed joint is then stamped and shaped using this method. To improve the shaping effect, the joint is repeatedly rotated. Current processing methods use three-jaw chucks or custom-made fixtures to fix the joint. After one or more stamping cycles, the joint is manually rotated for further stamping and shaping. However, the ease of operation still needs improvement. To address these issues, a new fixture for shaping the inner hole of a joint is proposed. Utility Model Content

[0018] In this invention, the clamping mechanism and the adjusting mechanism work together to center and clamp the joint workpiece, resulting in high clamping efficiency. This facilitates the shaping of the inner hole of the joint by the shaping rod in the subsequent shaping equipment. The three-way synchronous clamping avoids deformation of the joint workpiece caused by uneven force. The rotating mechanism assists the rotation of the support frame, clamping mechanism, and adjusting mechanism, avoiding frequent operation of the operator's hands in the clamping area.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0027] 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.

[0028] Please see Figures 1-5 In this embodiment, a tooling for shaping the inner hole of a connector includes...

[0029] The support frame 1 includes a three-pronged strut 11, a support rod 12 connected to the end of the three-pronged strut 11, and a rotating disk 13 connected to the bottom of the support rod 12. The support frame 1 serves as the basic load-bearing structure of the entire tooling and forms a triangular stable support structure through the three-pronged strut 11 to support and place the joint.

[0030] Rotating mechanism 2 is used to drive the support frame 1 to rotate;

[0031] The clamping mechanism 3 includes a toggle block 31 and a rotating shaft 32 connected to the toggle block 31 and rotatably engaged with the end of the trident support rod 11. Positioning blocks 33 are installed at both ends of the rotating shaft 32, and clamping members with adjustable horizontal positions are installed on the positioning blocks 33.

[0032] And the adjustment mechanism 4, which includes a mounting plate 41 and three sets of connecting rods 42 rotatably connected to the top of the mounting plate 41. The top end of the connecting rod 42 is rotatably connected to a connecting rod 43. The end of the connecting rod 43 away from the connecting rod 42 is fixedly connected to a toggle block 31. The rotating plate 13 is equipped with a lifting component for adjusting the lifting of the mounting plate 41.

[0033] Using the above scheme, the clamping mechanism 3 is rotatably engaged with the end of the three-pronged support rod 11 via the rotating shaft 32. The actuating block 31 can drive the rotating shaft 32 to rotate, thereby achieving the initial adjustment of the clamping angle. The three sets of clamping parts cooperate to fix the joint placed on the three-pronged support rod 11. Subsequently, the rotation mechanism 2 can be used to achieve the overall rotation adjustment of the support frame 1, which facilitates the fixing and rotation of the joint and makes it easy to shape the inner hole of the joint.

[0034] Please see Figure 4 The rotating mechanism 2 includes a large gear 21, a small gear 22, and a drive source 23. The large gear 21 is fixedly installed at the bottom of the rotating disk 13. The small gear 22 meshes with the large gear 21, but does not contact the rotating disk 13. The drive shaft at the power output end of the drive source 23 is connected to the shaft end of the small gear 22. The drive source 23 has a mounting base on the side away from the rotating disk 13. The drive source 23 is a servo motor or a stepper motor.

[0035] Specifically, the drive source 23 outputs power to drive the pinion 22 to rotate. The pinion 22 meshes with the large gear 21 fixed at the bottom of the rotating disk 13, transmitting power to the rotating disk 13, thereby driving the support frame 1 and the components connected to the support frame 1 to rotate as a whole, which can drive the joint to rotate and adjust its position.

[0036] In actual use, the rotating disk 13 is rotatably mounted on the shaping equipment, and the drive source 23 can be fixed on the shaping equipment through the mounting base.

[0037] Please see Figure 2 and 5 The clamping member includes a movable rod 34 and a clamping post 35 fixedly connected to the end of the movable rod 34. The positioning block 33 is provided with a rectangular hole for the movable rod 34 to slide. A clamping bolt 36 is threadedly connected to one side of the positioning block 33. The rod end of the clamping bolt 36 extends into the rectangular hole and contacts the side wall of the movable rod 34.

[0038] Specifically, the movable rod 34 can slide along the rectangular hole to adjust the horizontal position of the clamping column 35, adapting to workpieces of different sizes. After adjustment, the movable rod 34 is fixed by tightening the clamping bolt 36. The horizontal position of the clamping column 35 is adjustable, adapting to various specifications of joint inner hole workpieces, and has strong versatility.

[0039] Furthermore, the outer wall of the clamping column 35 is connected to an anti-slip rubber pad, which enhances the friction between the clamping column 35 and the workpiece and reduces damage to the workpiece during clamping.

[0040] Please see Figure 3 and 4 The top of the mounting plate 41 is fixedly connected to the guide post 45, and the bottom of the center of the three-pronged support rod 11 is fixedly connected to the guide sleeve 14. The outer wall of the guide post 45 is in sliding contact with the inner wall of the guide sleeve 14.

[0041] Specifically, as the mounting plate 41 rises and falls, the guide column 45 slides along the inner wall of the guide sleeve 14 at the bottom of the three-pronged strut 11 to ensure the straightness of the lifting and lowering of the mounting plate 41.

[0042] Please see Figure 3 The lifting component includes an electric telescopic rod 44 installed on the top of the rotating disk 13, and the movable rod end at the top of the electric telescopic rod 44 is connected to the center of the bottom of the mounting disk 41.

[0043] Specifically, the electric telescopic rod 44 drives the mounting plate 41 to rise and fall. When the mounting plate 41 rises and falls, it drives the three sets of connecting rods 42 to rotate. The connecting rods 42 pull the actuating block 31 through the connecting rod 43, thereby adjusting the opening angle of the clamping mechanism 3 and realizing the adjustment of the clamping tightness of the workpiece.

[0044] Please see Figure 3 The mounting plate 41 is fixedly connected to a rotating block at its top. Three sets of rotating blocks are arranged in a circular array, and the three sets of rotating blocks correspond to the three rod positions of the three-pronged support rod 11. The mounting plate 41 is rotatably connected to the connecting rod 42. The three sets of connecting rods 42 correspond to the three-pronged support rod 11, ensuring uniform force distribution, avoiding deformation of the clamping mechanism 3 due to force on one side, and extending the service life of the equipment.

[0045] The working principle of this utility model is as follows:

[0046] Before starting, the electric telescopic rod 44 is in the extended state, pushing the mounting plate 41 to a higher position. Through the linkage mechanism composed of three sets of connecting rods 42 and connecting rods 43, the actuating block 31 is pushed to an angle that opens the clamping mechanism 3. At this time, the space between the three clamping columns 35 is the largest. The operator places the joint workpiece to be shaped on the top of the three-pronged support rod 11.

[0047] The electric telescopic rod 44 retracts, pulling the mounting plate 41 downward. As the mounting plate 41 moves downward, the lower ends of the three sets of connecting rods 42 also descend. Since the connecting rods 42 and the mounting plate 41 are rotatably connected, their upper ends will retract towards the central axis. The retraction movement of the connecting rods 42 is transmitted to the actuating block 31 through the connecting rod 43. The connecting rod 43 moves downward near the end of the connecting rod 42, forcing the actuating block 31 to rotate around the axis of the rotating shaft 32. The positioning blocks 33 fixed at both ends of the rotating shaft 32 rotate, ultimately causing the tops of the three clamping columns 35 to tilt and approach the workpiece, thereby clamping the workpiece evenly from three directions.

[0048] If the workpiece dimensions vary, the position of each moving rod 34 in the rectangular hole of the positioning block 33 can be manually fine-tuned, and then the clamping bolt 36 can be tightened to fix it, thus achieving coarse adjustment. The anti-slip rubber pad protects the workpiece surface and increases friction.

[0049] When the workpiece is clamped and multi-angle shaping is required, the rotating mechanism 2 is started, the drive source 23 works, driving the small gear 22 to rotate, and the large gear 21 drives the entire support frame 1 to rotate.

[0050] The tooling can be installed in the forming equipment. The forming rod in the forming equipment is pressed into the inner hole of the joint from above the joint workpiece to perform forming stamping. Repeated stamping and rotation of the joint workpiece restores the roundness of the inner hole.

[0051] After the shaping is completed, the electric telescopic rod 44 extends again, the mounting plate 41 rises, and the three clamping columns 35 open, allowing the operator to remove the repaired workpiece.

[0052] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
