Description

Technical Field

[0001] This utility model belongs to the technical field of clamping and processing equipment, and in particular relates to a clamping device for processing cold-extruded non-ferrous metal parts. Background Technology

[0002] While various automated or semi-automated clamping solutions exist for the machining and clamping of cold-extruded non-ferrous metal parts, they still fall short of meeting the demands for high-efficiency, high-precision, and high-volume production in practical applications. For example, most current clamping equipment requires operators to clamp only one machine at a time, and each clamping operation necessitates stopping the machine to complete positioning, clamping, and alignment steps, resulting in long machine downtime, low equipment utilization, and severely restricting production efficiency. Furthermore, due to the low hardness and susceptibility to deformation of non-ferrous metals (such as aluminum and copper), traditional clamping devices like three-jaw chucks and pressure plate clamps are prone to clamping damage, deformation, or unstable positioning during clamping, especially when machining irregularly shaped cold-extruded parts, making it difficult to guarantee the stability and consistency of the machining process. Therefore, existing clamping equipment for machining cold-extruded non-ferrous metal parts still has significant shortcomings in terms of efficiency, precision, and stability, necessitating a new type of clamping equipment that can achieve multi-process machining in a single clamping operation while ensuring clamping stability and machining accuracy. Utility Model Content

[0003] In view of this, the present invention aims to provide a clamping device for processing cold-extruded non-ferrous metal parts, so as to solve the problem that the existing clamping devices have low clamping efficiency and poor clamping effect when clamping cold-extruded non-ferrous metal parts, which affects the processing efficiency and processing quality of the parts.

[0004] To achieve the above objectives, the technical solution of this utility model is implemented as follows: A clamping device for processing cold-extruded non-ferrous metal parts includes an indexing head and a rotating tailstock. The indexing head and the rotating tailstock are connected by a bridge plate. The bridge plate and the indexing head, as well as the bridge plate and the rotating tailstock, are detachably connected. The bridge plate is provided with assembly holes for cooperating with the parts to be processed. Multiple assembly holes are provided along the length of the bridge plate. The bridge plate is provided with deformation holes located on the side of the assembly holes facing the edge of the bridge plate, and the two ends of the deformation holes are respectively connected to two adjacent assembly holes. Fasteners are provided on the side wall of the bridge plate. The bridge plate is provided with mounting holes and threaded holes for installing the fasteners. The mounting holes and the threaded holes are respectively located on both sides of the deformation holes, and both are connected to the deformation holes. The threaded holes are located between two adjacent assembly holes. One end of the fastener passes through the mounting hole and the deformation hole and is threadedly connected to the threaded hole. The other end is provided with a limiting part that can abut against the side wall of the bridge plate.

[0005] Furthermore, the assembly holes are arranged in pairs, and each pair of assembly holes is connected by a deformation hole.

[0006] Furthermore, the deformation hole is a strip-shaped hole, and the length direction of the strip-shaped hole is the same as the length direction of the bridge plate.

[0007] Furthermore, the assembly hole is a circular hole, and one inner wall of the deformation hole is tangent to the inner wall of the assembly hole.

[0008] Furthermore, the bridge plate is provided with a first elastic deformation part and a second elastic deformation part at the position between two adjacent mounting holes. The first elastic deformation part and the second elastic deformation part are respectively located on both sides of the deformation hole. The mounting hole is located in the first elastic deformation part, and the threaded hole is located in the second elastic deformation part.

[0009] Furthermore, the fastener includes a smooth rod portion and a threaded portion, the diameter of the smooth rod portion is larger than the diameter of the threaded portion, and the smooth rod portion and the threaded portion are transitioned by a guide cone surface; the second elastic deformation portion is provided with a deformation opening that can cooperate with the guide cone surface, the length direction of the deformation opening is the same as the length direction of the threaded hole, and the two are connected.

[0010] Furthermore, the inner wall of the deformation opening is provided with a guide slope that can cooperate with the guide cone surface.

[0011] Compared with the prior art, the clamping equipment for processing cold-extruded non-ferrous metal parts according to this utility model has the following advantages: This utility model discloses a clamping device for processing cold-extruded non-ferrous metal parts. It features a simple structure, ease of operation and use, and is suitable for clamping and processing cold-extruded non-ferrous metal parts. It provides good clamping and fixing effects, high efficiency, and is less likely to damage the parts after clamping, thus improving processing efficiency and accuracy. By setting mounting holes on the bridge plate that conform to the shape of the workpiece, and utilizing the limiting parts on the fasteners to abut against the bridge plate to achieve elastic deformation, the workpiece can remain stable under the clamping of the inner sidewall of the conforming mounting holes. This further improves the stability and uniformity of clamping the workpiece, reducing the possibility of deformation before and after clamping. Attached Figure Description

Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; 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; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0018] A clamping device for processing cold-extruded non-ferrous metal parts, such as Figures 1 to 4 As shown, the device includes an indexing head 1 and a rotating tailstock 2. The indexing head 1 and the rotating tailstock 2 are connected by a bridge plate 3. The bridge plate 3 is detachably connected to both the indexing head 1 and the rotating tailstock 2. Specifically, the bridge plate 3 and the indexing head 1, and the bridge plate 3 and the rotating tailstock 2, can be detachably connected using bolts or other methods. This invention does not involve any improvement to the indexing head 1 and the rotating tailstock 2. Those skilled in the art can select appropriate indexing heads 1 and rotating tailstock 2 according to actual needs, and choose other suitable methods to achieve the detachable assembly of the bridge plate 3 on the indexing head 1 and the rotating tailstock 2, so that the bridge plate 3 can rotate under the drive of the indexing head 1 and the rotating tailstock 2, facilitating the subsequent processing of the workpiece clamped on the bridge plate 3. Further details are omitted here.

[0019] The main improvement of this utility model lies in the bridge plate 3. Specifically, the bridge plate 3 is provided with assembly holes 7 that mate with the parts to be processed. Multiple assembly holes 7 are provided along the length of the bridge plate 3. The bridge plate 3 is provided with deformation holes 6, which are located on the side of the assembly holes 7 facing the edge of the bridge plate 3, and both ends of the deformation holes 6 are respectively connected to two adjacent assembly holes 7. Fasteners 5 are provided on the side wall of the bridge plate 3. The bridge plate 3 is provided with mounting holes and threaded holes 12 for installing the fasteners 5. The mounting holes and threaded holes 12 are respectively located on both sides of the deformation holes 6, and both are connected to the deformation holes 6. The threaded holes 12 are located between two adjacent assembly holes 7. One end of the fastener 5 passes through the mounting hole and the deformation hole 6 and is threadedly connected to the threaded hole 12. The other end is provided with a limiting part 10 that can abut against the side wall of the bridge plate 3. The diameter of the limiting part 10 is larger than the diameter of the mounting hole.

[0020] Using the above configuration, when it is necessary to clamp and fix the workpiece 4 to be processed on the bridge plate 3, the workpiece 4 can be inserted into the assembly hole 7 first, and the assembly hole 7, which is contoured to the workpiece, can be used to achieve initial positioning. Then, the fastener 5 is tightened, and the fastener 5 cooperates with the threaded hole 12, so that the limiting part 10 on the fastener 5 can push the side wall of the bridge plate 3 to move towards the middle of the bridge plate 3 and undergo elastic deformation. At this time, the deformation hole 6 can meet the elastic deformation stroke requirements of the side wall of the bridge plate 3. In this way, under the abutting action of the upper limiting part 10 of the fastener 5, the inner wall of the assembly hole 7 can clamp and fix the workpiece 4 to be processed, so as to ensure that the workpiece 4 remains stable during subsequent processing.

[0021] Correspondingly, when the workpiece is finished and needs to be removed, the fastener 5 can be turned in the opposite direction to release the pushing force of the upper limit part 10 of the fastener 5 on the side wall of the bridge plate 3. After the inner side wall of the assembly hole 7 is no longer clamped and fixed to the workpiece, the workpiece can be easily picked up and put down. The operation is very simple. Moreover, since the elastic deformation force of the bridge plate 3 is small, it is not easy to damage the workpiece 4 to be processed during the clamping process. This is conducive to improving the reliability, stability, safety and clamping efficiency of this equipment when clamping cold extruded non-ferrous metal parts.

[0022] In a preferred embodiment of this invention, the assembly holes 7 are arranged in pairs, with each pair of assembly holes 7 connected by a deformation hole 6. By arranging multiple assembly holes 7 in pairs, the workpiece 4 to be processed can be clamped and fixed together by two assembly holes 7 in the same group, which is beneficial to improving the clamping and fixing effect of the workpiece 4 to be processed by this device. In addition, by setting multiple sets of assembly holes 7, multiple workpieces 4 to be processed can be clamped on one bridge plate 3 at one time, which is beneficial to improving the processing efficiency of the workpiece 4 to be processed.

[0023] In a preferred embodiment of this invention, the deformation hole 6 is a strip-shaped hole, and the length direction of the strip-shaped hole is the same as the length direction of the bridge plate 3. By using a strip-shaped hole as the deformation hole 6 and setting the length direction of the deformation hole 6 to be the same as the length direction of the bridge plate 3, the deformation hole 6 can be set along the edge of the bridge plate 3, making it easier for elastic deformation to occur at the deformation hole 6 at the edge of the bridge plate 3. This helps to reduce the difficulty of tightening the fastener 5 and improve the service life and reliability of the fastener 5.

[0024] In practical applications, the assembly hole 7 is a circular hole, and one inner wall of the deformation hole 6 is tangent to the inner wall of the assembly hole 7. Specifically, the inner wall of the deformation hole 6 near the edge of the bridge plate is tangent to the inner wall of the assembly hole 7. Thus, when the fastener 5 is tightened, as the fastener 5 continuously presses against the side wall of the bridge plate 3, causing elastic deformation at the edge of the bridge plate 3, the inner wall of the assembly hole 7 will also deform and move towards the center of the bridge plate 3. This, in turn, can drive the inner wall of the assembly hole 7 to deform and move, enabling the inner wall of the assembly hole 7 to further clamp and fix the workpiece 4 to be processed in the length direction of the fastener 5, which is beneficial to improving the clamping and fixing effect of this equipment on the workpiece 4 to be processed.

[0025] In a preferred embodiment of this invention, a first elastic deformation portion 8 and a second elastic deformation portion 9 are provided on the bridge plate 3 at positions corresponding to two adjacent mounting holes 7. The first elastic deformation portion 8 and the second elastic deformation portion 9 are respectively located on both sides of the deformation hole 6. The mounting hole is located in the first elastic deformation portion 8, and the threaded hole 12 is located in the second elastic deformation portion 9. Specifically, the first elastic deformation portion 8 is located on the side of the deformation hole 6 near the sidewall of the bridge plate 3, while the second elastic deformation portion 9 is located on the side of the deformation hole 6 near the middle of the bridge plate 3. It should be noted that, to ensure better elastic deformation performance of the first elastic deformation portion 8, its thickness can be reduced, or it can be made of materials such as spring steel.

[0026] For example, the fastener 5 includes a smooth rod portion 14 and a threaded portion 13. The diameter of the smooth rod portion 14 is larger than the diameter of the threaded portion 13, and the smooth rod portion 14 and the threaded portion 13 are connected by a guide cone surface 15. The second elastic deformation portion 9 is provided with a deformation opening 11 that can cooperate with the guide cone surface 15. The length direction of the deformation opening 11 is the same as the length direction of the threaded hole 12, and the two are connected.

[0027] Using the above configuration, when the fastener 5 is tightened and the limiting part 10 on the fastener 5 abuts against the side wall of the bridge plate 3, the limiting part 10 can push the first elastic deformation part 8 to deform, thereby clamping and fixing the workpiece 4 to be processed along the length direction of the fastener 5. At the same time, as the guide cone surface 15 on the fastener 5 extends into the deformation opening 11, the guide cone surface 15, whose diameter gradually increases, can also push the deformation opening 11 to expand along the inner side wall of the deformation opening 11, thereby pushing the second elastic deformation part 9 on both sides of the deformation opening 11 to deform. At this time, the second elastic deformation part 9 can drive the remaining inner side wall of the assembly hole 7 to clamp and fix the workpiece 4 to be processed along the length direction of the bridge plate 3. In this way, the workpiece 4 to be processed can be clamped not only by the inner wall of the mounting hole 7 in the length direction of the fastener 5, but also by the inner wall of the mounting hole 7 in the length direction of the bridge plate 3, so as to realize the all-round clamping and fixing of the workpiece 4 to be processed, further improving the stability and uniformity of the clamping device for the workpiece 4 to be processed, reducing the possibility of deformation of the workpiece 4 to be processed before and after clamping, thereby helping to improve the processing accuracy and processing quality of the workpiece 4 to be processed.

[0028] Optionally, the inner wall of the deformation opening 11 is provided with a guide slope that can cooperate with the guide cone surface 15. By providing a guide slope on the inner wall of the deformation opening 11, when the fastener 5 is tightened and the guide cone surface 15 on the fastener 5 extends into the deformation opening 11, the guide cone surface 15 can cooperate better with the guide slope, reducing friction and blockage, ensuring that the guide cone surface 15 can smoothly and continuously penetrate into the deformation opening 11, and driving the deformation opening 11 to expand and cause the second elastic deformation part 9 to deform.

[0029] Optionally, fastener 5 can be an M6 screw. In this case, the clamping equipment for processing cold-extruded non-ferrous metal parts can be used with reference to the following steps: S1. Install the indexing head 1, the rotating tailstock 2, and the bridge plate 3 onto the CNC equipment work platform. Use a dial indicator to adjust the position and straightness of the indexing head 1, the rotating tailstock 2, and the bridge plate 3 relative to the T-slot of the CNC equipment. After adjustment, use M12 bolts to tighten the indexing head 1 and the rotating tailstock 2 to the T-slot of the CNC equipment and fix them in place.

[0030] S2. Place the workpiece 4 to be processed into the pre-machined contoured cavity (i.e., assembly hole 7), and tighten the M6 ​​screws with an electric screwdriver each time to clamp and fix the workpiece 4 to be processed.

[0031] S3. Click the CNC equipment cycle button to process multiple parts at once.

[0032] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
