Description

Technical Field

[0001] This utility model belongs to the field of machining technology, specifically relating to a fixture for aircraft cargo hold parts. Background Technology

[0002] Because cargo inside the aircraft cabin can shift during flight if not secured, it poses a flight safety hazard. Therefore, securing cargo within the cabin to prevent movement is essential. A cargo hold floor can be covered with a positioning layer composed of small modular units, making it easy to install and remove.

[0003] Utility model patent CN217434177U discloses a special fixture for machining parts used in aircraft cargo hold flooring, including a base, a limiting component, and a pressure block. This fixture positions and clamps the workpiece, but it cannot perform symmetrical machining on both sides of the part. Utility Model Content

[0004] To address the technical problem of symmetrical machining of both sides of a part, this utility model provides a fixture for aircraft cargo hold parts.

[0005] To achieve the objective of this utility model, the technical solution adopted by this utility model is as follows:

[0006] A clamp for aircraft cargo hold parts includes a base plate, a pressure plate, and a support plate. The base plate has a screw hole with a screw installed in it. The pressure plate is fitted onto the screw. A first return spring is provided between the pressure plate and the support plate. Vertical positioning rods are provided on both sides of the screw hole. The pressure plate has two positioning holes, with the tops of the two positioning rods located in the corresponding positioning holes. A groove is also provided on both sides of the screw hole, located directly below the pressure plate. A support plate is inserted into the groove. A pin hole is provided at the bottom of the support plate, with a limit pin inserted in it. Vertical grooves corresponding to the ends of the limit pins are provided on the opposite side walls of the groove. A second return spring is provided below the support plate.

[0007] The groove of this invention has limiting grooves on its opposite side walls to accommodate the second reset spring.

[0008] The pin hole of this invention is located on the protrusion at the bottom of the support plate, and a second return spring is respectively abutted on both sides of the protrusion.

[0009] The base plate of this utility model is provided with two sets of pressure plates and corresponding support plates.

[0010] The support plate of this utility model is provided with a positioning plate at its top end, and the pressure plate is provided with a positioning groove corresponding to the positioning plate.

[0011] Preferably, when the second return spring is in a free state, the positioning plate does not dislodge from the positioning groove.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. By turning the nut upwards, the pressure plate moves upwards under the action of the first return spring. After the part is installed, turning the nut downwards presses the pressure plate down. Under the action of the second return spring, the support plate is pushed upwards, allowing the pressure plate and support plate to clamp the part more securely. The support plate not only serves as a clamping device but also acts as the central axis of the part, enabling symmetrical machining of both sides of the part.

[0014] 2. A positioning plate is installed at the top of the support plate, and a corresponding positioning groove is provided on the pressure plate. This ensures that the support plate and the pressure plate will not shift when moving up and down, making the movement smoother. Attached Figure Description

[0020] To more clearly and in detail illustrate the objective technical solution of this utility model, the present utility model will be further described below through relevant embodiments. The following embodiments are merely illustrative of the implementation methods of this utility model and do not limit the scope of protection of this utility model.

[0021] Example 1

[0022] like Figure 1As shown, a jig for aircraft cargo hold parts includes a base plate 1, a pressure plate 2, and a support plate 3. The base plate 1 has a screw hole 11, a screw 4 is provided in the screw hole 11, and the pressure plate 2 is sleeved on the screw 4. A first return spring 5 is provided between the pressure plate 2 and the support plate 3. Vertical positioning rods 7 are provided on both sides of the screw hole 11. The pressure plate 2 has two positioning holes 21, and the tops of the two positioning rods 7 are located in the corresponding positioning holes 21. A groove 12 is also provided on both sides of the screw hole 11. The groove 12 is located directly below the pressure plate 2, and a support plate 3 is inserted into the groove 12. The bottom of the support plate 3 has a pin hole, and a limit pin 8 is inserted into the pin hole. Vertical sliding grooves 121 corresponding to the ends of the limit pins 8 are provided on the opposite side walls of the groove 12. A second return spring 6 is provided below the support plate 3.

[0023] Turn the nut 41 upwards. Under the action of the first return spring 5, the pressure plate 2 moves upwards, inserting the part 10 along the support plate 3. Figure 4 After part 10 is installed, turn the nut downwards and the pressure plate presses down. Under the action of the second return spring 6, the support plate 3 is pushed upwards, so that the pressure plate 2 can fix part 10 more securely.

[0024] Example 2

[0025] This example is based on Example 1:

[0026] The opposite side walls of the groove 12 are provided with limiting grooves 122 to accommodate the second reset spring 6, so that the second reset spring 6 fits more closely with the support plate 3 and the groove 12, and the support plate 3 is more stable when moving up and down.

[0027] Example 3

[0028] This example is based on Example 1:

[0029] The pin hole is located on the protrusion at the bottom of the support plate 3, and a second return spring 6 is respectively abutted on both sides of the protrusion, making the up and down movement more stable.

[0030] The base plate 1 is provided with two sets of pressure plates 2 and corresponding support plates 3.

[0031] Example 4

[0032] This example is based on Example 1:

[0033] The top of the support plate 3 is provided with a positioning plate 9, and the pressure plate 2 is provided with a positioning groove 22 corresponding to the positioning plate 9. This ensures that the support plate 3 and the pressure plate 2 will not shift when moving up and down, making the movement smoother.

[0034] When the second reset spring 6 is in a free state, the positioning plate 9 does not dislodge from the positioning groove 22.

[0035] Connection methods not mentioned in this utility model include welding, snap-fitting, riveting, hinge, threaded connection, or bonding.

[0036] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
