Description

Technical Field

[0001] This utility model relates to the field of clamping carrier technology, specifically a thin-walled shell processing anti-deformation metal clamping carrier. Background Technology

[0002] The anti-deformation metal clamping carrier for thin-walled shell machining is an auxiliary tooling specifically designed to address the issue of deformation due to insufficient rigidity during the machining of thin-walled parts. It is typically made of high-strength, low-expansion-coefficient metals (such as aluminum alloys and alloy steels). Through a precision structure that conforms to the shell's shape, it provides uniform clamping force from multiple directions, preventing deformation caused by single-point stress. Its core function is to provide rigid support for the shell throughout the entire machining process (such as milling and drilling), ensuring dimensional accuracy and shape stability. After machining, it can be separated from the workpiece through a specific structure (such as a breakable groove). It is widely used in the efficient machining of thin-walled components in aerospace, precision instruments, and other fields.

[0003] Chinese Patent No. 202421381604.0 discloses a clamping device for preventing deformation during the processing of thin-walled metal parts, including a base, a bidirectional threaded rod disposed at the center of the base, a crank handle disposed on one side of the base, threaded plates threadedly connected to both sides of the surface of the bidirectional threaded rod, and a spacer disposed at the center of the surface of the bidirectional threaded rod.

[0004] When this utility model is in use, the spring of the clamping plate is prone to shaking when clamping, which leads to unstable clamping and causes the material to shake. Utility Model Content

[0005] The purpose of this invention is to provide a thin-walled shell processing anti-deformation metal clamping carrier to solve the problems raised in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a thin-walled shell processing anti-deformation metal clamping carrier, including a clamping device, the clamping device consisting of a placement platform, a moving mechanism and a clamping mechanism, the moving mechanism being installed at both ends of the placement platform, the clamping mechanism being installed on the upper side of the moving mechanism, a placement groove being provided at the upper end of the placement platform, a sliding groove being provided around the inside of the placement groove, an adjusting plate being slidably installed inside the sliding groove, an adjusting mechanism being installed on one side of the adjusting plate, and the adjusting mechanism being installed around the outside of the placement platform.

[0007] Preferably, the adjustment mechanism consists of a first telescopic rod and a mounting frame, wherein the first telescopic rod is installed at both ends of the placement platform, and the mounting frame is installed at the front end of the first telescopic rod.

[0008] Preferably, the clamping mechanism consists of a second telescopic rod and a clamping plate, wherein the second telescopic rod is installed on one side of the upper end of the moving mechanism, and the clamping plate is installed on the bottom end of the second telescopic rod.

[0009] Preferably, a rubber pad is provided at the bottom end of the clamping plate, and the rubber pad is attached to the bottom end of the clamping plate with adhesive.

[0010] Preferably, the moving mechanism consists of a threaded rod and a threaded cylinder. The threaded cylinder is installed around the placement platform at the corresponding slide groove position. The threaded rod is rotatably installed inside the threaded cylinder, and one end of the threaded rod extends into the slide groove and is rotatably installed below one side of the clamping plate.

[0011] Preferably, a handle is provided on the outer side of the threaded rod, and the handle is installed on one side of the threaded rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. The adjustment mechanism drives the adjustment plate to move along the slide groove, which can reduce or expand the effective space of the placement groove according to the actual size of the thin-walled shell, so that the placement groove fits the outer wall of the workpiece and prevents the workpiece from shaking in the groove; the moving mechanism at both ends of the placement table can adjust the lateral position of the clamping mechanism, so that the clamping mechanism is precisely aligned with the clamping point of the workpiece; the clamping mechanism applies a stable and uniform clamping force to the workpiece through its own action, fixing the workpiece in the placement groove.

[0014] 2. After the thin-walled shell workpiece is placed in the placement slot and positioned by the adjusting plate, the moving mechanism adjusts the clamping mechanism to a suitable position. Then, the second telescopic rod extends, driving the clamping plate downward until the bottom of the clamping plate contacts the upper surface of the workpiece and applies a certain pressure. The clamping force is controlled by the extension and retraction of the second telescopic rod, which firmly fixes the workpiece in the placement slot to prevent workpiece displacement during processing. After processing is completed, the second telescopic rod retracts, driving the clamping plate upward to release the clamping of the workpiece and facilitate removal.

[0015] 3. When the clamping plate clamps the workpiece downwards under the action of the second telescopic rod, the rubber pad directly contacts the upper surface of the thin-walled shell workpiece. The rubber pad has a certain elasticity and can undergo slight deformation during clamping, increasing the contact area with the workpiece surface and distributing the clamping force evenly in the contact area, thus avoiding rigid contact between the clamping plate and the workpiece. At the same time, the friction coefficient of the rubber pad is higher than that of metal, which can enhance the friction between the clamping plate and the workpiece and prevent the workpiece from sliding during processing.

[0016] 4. When it is necessary to adjust the position of the clamping mechanism, rotate the threaded rod. The threaded rod moves axially under the thread constraint of the threaded cylinder, thereby driving the clamping plate connected to it to move along the direction of the slide groove. By rotating the threaded rod forward or backward, the clamping plate can be moved closer to or further away from the center of the placement groove until it is adjusted to a suitable clamping position.

[0023] 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.

[0024] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 In this embodiment of the utility model, a thin-walled shell processing anti-deformation metal clamping carrier includes a clamping device 1. The clamping device 1 consists of a placement platform 2, a moving mechanism 3, and a clamping mechanism 4. The moving mechanism 3 is installed at both ends of the placement platform 2, and the clamping mechanism 4 is installed on the upper side of the moving mechanism 3. A placement groove 5 is provided at the upper end of the placement platform 2. A sliding groove 11 is provided around the inside of the placement groove 5. An adjusting plate 6 is slidably installed inside the sliding groove 11 to adjust the size of the placement groove 5 according to the size of the material. An adjusting mechanism 7 is installed on one side of the adjusting plate 6 and is installed around the outside of the placement platform 2.

[0025] The adjustment mechanism 7 consists of a first telescopic rod 12 and a mounting frame 14. The first telescopic rod 12 is installed at both ends of the placement platform 2, and the mounting frame 14 is installed at the front end of the first telescopic rod 12. When it is necessary to adjust the size of the placement slot 5, the first telescopic rod 12 is extended or shortened. The telescopic end drives the adjustment plate 6 to slide along the slide groove 11 through the mounting frame 14. If the workpiece size is small, the first telescopic rod 12 retracts, pulling the adjustment plate 6 towards the center of the placement slot 5, reducing the effective space of the placement slot 5. If the workpiece size is large, the first telescopic rod 12 extends, pushing the adjustment plate 6 towards the edge of the placement slot 5, expanding the effective space of the placement slot 5, until the adjustment plate 6 is tightly fitted to the outer wall of the workpiece.

[0026] The clamping mechanism 4 consists of a second telescopic rod 13 and a clamping plate 16. The second telescopic rod 13 is installed on one side of the upper end of the moving mechanism 3, and the clamping plate 16 is installed on the bottom end of the second telescopic rod 13. When the thin-walled shell workpiece is placed in the placement slot 5 and positioned by the adjusting plate 6, the moving mechanism 3 adjusts the clamping mechanism 4 to a suitable position. Then, the second telescopic rod 13 extends, driving the clamping plate 16 to move downward until the bottom end of the clamping plate 16 contacts the upper surface of the workpiece and applies a certain pressure. The clamping force is controlled by the extension and retraction force of the second telescopic rod 13, which firmly fixes the workpiece in the placement slot 5 to prevent workpiece displacement during processing. After processing is completed, the second telescopic rod 13 retracts, driving the clamping plate 16 to move upward, releasing the clamp on the workpiece and facilitating removal.

[0027] A rubber pad 15 is provided at the bottom end of the clamping plate 16, and the rubber pad 15 is attached to the bottom end of the clamping plate 16 with adhesive. When the clamping plate 16 clamps the workpiece downward under the action of the second telescopic rod 13, the rubber pad 15 directly contacts the upper surface of the thin-walled shell workpiece. The rubber pad 15 has a certain degree of elasticity and can undergo slight deformation during clamping, increasing the contact area with the workpiece surface and distributing the clamping force evenly in the contact area, thus avoiding rigid contact between the clamping plate 16 and the workpiece. At the same time, the coefficient of friction of the rubber pad 15 is higher than that of metal, which can enhance the friction between the clamping plate 16 and the workpiece and prevent the workpiece from sliding during processing.

[0028] The moving mechanism 3 consists of a threaded rod 9 and a threaded cylinder 8. The threaded cylinder 8 is installed around the placement platform 2 at positions corresponding to the slide groove 11. The threaded rod 9 is rotatably installed inside the threaded cylinder 8, with one end of the threaded rod 9 extending into the slide groove 11 and rotatably installed below one side of the clamping plate 16. When it is necessary to adjust the position of the clamping mechanism 4, the threaded rod 9 is rotated, and the threaded rod 9 moves axially under the thread constraint of the threaded cylinder 8, thereby driving the clamping plate 16 connected to it and the second telescopic rod 13 above it to move along the slide groove 11. By rotating the threaded rod 9 forward or backward, the clamping plate 16 can be moved closer to or further away from the center of the placement groove 5 until it is adjusted to a suitable clamping position.

[0029] A handle 10 is provided on the outside of the threaded rod 9, and the handle 10 is installed on one side of the threaded rod 9. The handle 10 is fixedly connected to one side of the threaded rod 9 to form a force-saving lever structure. When it is necessary to rotate the threaded rod 9 to adjust the position of the moving mechanism 3, the operator holds the handle 10 and applies a rotational force. The lever effect of the handle 10 amplifies the force, making it easier for the threaded rod 9 to rotate inside the threaded cylinder 8, thereby driving the clamping plate 16 to move. The clockwise / counterclockwise rotation direction of the handle 10 controls the forward or reverse rotation of the threaded rod 9, thereby moving the clamping plate 16 closer or further away.

[0030] The working principle and usage process of this utility model are as follows: The placement groove 5 at the upper end of the placement platform 2 is used to position the thin-walled shell workpiece, and the sliding groove 11 around the groove provides a sliding track for the adjustment plate 6; the adjustment mechanism 7 drives the adjustment plate 6 to move along the sliding groove 11, which can reduce or expand the effective space of the placement groove 5 according to the actual size of the thin-walled shell, so that the placement groove 5 fits against the outer wall of the workpiece and prevents the workpiece from shaking in the groove; the moving mechanism 3 at both ends of the placement platform 2 can adjust the lateral position of the clamping mechanism 4, so that the clamping mechanism 4 is accurately aligned with the clamping point of the workpiece; the clamping mechanism 4 applies a stable and uniform clamping force to the workpiece through its own action, fixing the workpiece in the placement groove 5, preventing the thin-walled shell from deforming due to uneven force or vibration during processing; the various mechanisms work together to achieve both adaptation to thin-walled shells of different sizes and ensure processing stability through the dual fixation of "positioning + clamping".

[0031] Finally, it should be noted that the above are merely preferred embodiments of this utility model and are not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
