Description

Technical Field

[0001] The present application relates to the technical field of inner clamping tooling, and in particular to a support-disc type projectile inner clamping tooling. Background Art

[0002] During the production and maintenance of projectiles, various operations are often required to be performed on the interior of the projectile, such as inspection, cleaning, and repair. These operations usually require the use of clamps to fix and position the projectile.

[0003] However, the widely used three-jaw chuck clamping tool can provide a stable clamping force, but it cannot adjust its position inside the projectile, thereby limiting the flexibility and efficiency of the operation. Utility Model Content

[0004] The problem to be solved by the present application is that although the existing three-jaw chuck clamping tool for projectiles can provide a stable clamping force, it cannot adjust its position inside the projectile, thereby limiting the flexibility and efficiency of operation.

[0005] In order to solve the above technical problems, the present application provides a support disc type elastic body clamping tool, which is characterized in that it includes a support ring and a support plate, the cross-section of the support plate is arc-shaped, and the outer surface of the support plate is symmetrically arranged with surrounding support plates in the width direction, and the interior of the support ring is also arranged with an adjustment component for adjusting the expansion range of the support plate.

[0006] Since the internal clamping fixture of the present application is designed with a support ring, a support plate and an adjustment component, it is possible to achieve effective support inside the projectile through the support ring and the support plate, and the opening and closing angle of the support ring can be adjusted through the adjustment component to facilitate the removal and adjustment of the position of the support ring inside the projectile, thereby solving the problem that the existing three-jaw chuck clamping fixture for projectiles can provide a stable clamping force but cannot adjust its position inside the projectile, thereby limiting the flexibility and efficiency of the operation.

[0012] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application. Example

[0013] This application relates to a support disc type projectile body clamping tool, such as Figure 1-4 As shown, the inner clamping tool includes a support ring 3, a support plate 2, and a handle 6. The support ring 3 serves as the basic structure of the tool. The support ring 3 has sufficient strength and rigidity to withstand various forces and torques during operation. The inner surface of the support ring 3 is symmetrically provided with handles 6, which are convenient for the operator to hold and apply force. The design of the handle 6 conforms to the principle of ergonomics and can reduce hand fatigue during operation. The cross-section of the support plate 2 is arc-shaped, which matches the inner wall of the projectile 1 to ensure good contact and clamping effect. The support plate 2 has a notch 4, which makes it easy to enter and exit the interior of the projectile 1 during the clamping process. The outer surface of the support plate 2 is symmetrically arranged with support plates 2 arranged around it in the width direction. The adjustment component 5 is arranged inside the support ring 3 for adjusting the expansion amplitude of the support plate 2. By operating the adjustment component 5, the expansion degree of the support plate 2 can be accurately controlled to adapt to projectiles 1 of different diameters. The design of the adjustment component 5 is sophisticated and easy to operate, and the adjustment action of the support plate 2 can be completed in a short time.

[0014] The adjustment assembly 5 is mainly composed of a grip 12, a frame plate 13, a screw 8, a screw sleeve 7, a ratchet 9, a pawl 10 and a spring pin 11. The grip 12 is arranged between the frame plates 13. The grip 12 is the part that the operator directly holds. By moving the grip 12, the engagement state of the pawl 10 and the ratchet 9 can be controlled, thereby changing the rotation direction of the screw 8. The frame plates 13 are fixed on both sides of the ratchet 9 to support the pawl 10 and the spring pin 11 to ensure their stable operation. The screw 8 is a key component in the adjustment assembly 5. It is connected to the screw sleeve 7 through a thread. When the screw 8 rotates, the screw sleeve 7 will move axially along the screw 8. The screw sleeve 7 is symmetrically arranged on the inner side of the support ring 3 and can rotate freely. The threaded connection between the sleeve 7 and the screw 8 enables the sleeve 7 to move axially when the screw 8 rotates. The ratchet 9 is sleeved on the middle position of the upper part of the screw 8 and is fixedly connected to the screw 8. The function of the ratchet 9 is to transmit the movement of the grip 12 to the screw 8, thereby controlling the movement direction of the sleeve 7. The pawl 10 is arranged between the frame plates 13 and can be engaged with the ratchet 9. The pawl 10 is designed as a V-shaped structure that can be engaged in both directions, so that the grip 12 can control the rotation direction of the ratchet 9 when the grip 12 is in different positions. The spring pin 11 is arranged at the end of the grip 12, which can limit the pawl 10. Through the cooperation of the spring pin 11 and the pawl 10, the ratchet 9 can be engaged in one direction or two directions.

[0015] When using the support disc type clamping tooling of the present application for the projectile 1, the operator first adjusts the adjustment component 5 according to the diameter of the projectile 1 so that the support plate 2 reaches the appropriate expansion range, and then inserts the tooling into the projectile 1 through the handle 6 until it reaches the desired position. Finally, the clamping force is applied by the adjustment component 5 to make the support plate 2 fit tightly against the inner wall of the projectile 1, thereby achieving stable clamping and positioning. It should be noted that the physical size of the support ring 3 is not infinitely expandable. Under normal circumstances, the adjustment component 5 mainly drives the support ring 3 to shrink inward so that it can easily enter the interior of the projectile 1, and then expands it outward to a perfect circle state so that the support plate 2 can be in stable and uniform contact with the inner wall of the projectile 1. On this basis, appropriate fine-tuning can also be performed to reduce the possibility of the support plate 2 and the inner wall of the projectile 1 not being firmly fixed due to processing errors.

[0016] When the expansion range of the support plate 2 needs to be adjusted, the operator first determines the rotation direction of the screw 8 according to the needs; then, by moving the handle 12, the spring pin 11 is engaged with one side or the other side of the pawl 10;

[0017] When the spring pin 11 is engaged with one side of the pawl 10, one end of the pawl 10 can be engaged with the ratchet 9. At this time, rotating the handle 12 will drive the ratchet 9 and the screw 8 to rotate in one direction. As the screw 8 rotates, the two screw sleeves 7 will simultaneously move away from or towards each other along the axial direction of the screw 8, thereby adjusting the expansion range of the support plate 2.

[0018] When the rotation direction of the screw 8 needs to be changed, the operator only needs to move the handle 12 to the other side so that the spring pin 11 is engaged with the other side of the pawl 10. At this time, the other end of the pawl 10 will be engaged with the ratchet 9, thereby realizing the reverse rotation of the screw 8.
