Description

TECHNICAL FIELD

[0001] The utility model relates to aviation accessory processing technical field, concretely relates to a clamp for aviation accessory production and processing. BACKGROUND

[0002] In the aviation industry, the machining of aviation accessories is a highly demanding work in terms of precision and quality. These accessories not only need to meet strict design specifications, but also need to maintain extremely high precision and stability during the machining process. In order to achieve this goal, aviation accessory machining usually relies on special clamps, which are used to fix the accessories to ensure their accurate position during the machining process.

[0003] However, some existing aviation accessory machining clamps are too focused on fixing ability, i.e. ensuring that the accessories do not move during the machining process. Although it meets the basic fixing needs, it lacks sufficient flexibility. In the face of the increasingly complex machining requirements of aviation accessories, such as cutting, drilling and milling at multiple angles, these clamps often cannot effectively adapt. This lack of flexibility limits the efficiency and quality of the machining process, resulting in more time and labor required for machining complex accessories, and also increasing the possibility of machining errors. SUMMARY

[0004] Therefore, the utility model provides a clamp for aviation accessory production and processing, which can provide more machining angles for aviation accessories, improve the flexibility of the clamp, and meet various complex machining requirements.

[0005] To solve the above technical problems, the utility model provides a clamp for aviation accessory production and processing, which comprises a support table and an adjusting assembly. The top of the support table is inclined, and the higher side of the top of the support table is hingedly connected with a support plate. The middle part of the support plate is fixedly connected with a base, and the top of the base is provided with a clamping assembly. The adjusting assembly comprises two symmetrically distributed slide rails fixedly connected to the top of the support table. The middle part of each slide rail is rotatably connected with a screw rod, and the middle part of each screw rod is threadedly connected with a sliding block. The bottom of each sliding block is slidably connected with the adjacent slide rail. One end of each screw rod is fixedly connected with a chain wheel, and the two chain wheels are drivingly connected through a chain. The top of each sliding block is fixedly connected with a roller. The bottom of the support plate is fixedly connected with a plurality of guide frames, and the middle part of each roller is slidably connected with the middle part of the adjacent guide frame. This design allows the aviation accessory to have more machining angles when it is fixed by the clamping assembly, effectively improving the flexibility and adaptability of the clamp, and meeting various complex machining requirements.

[0006] The middle part of each roller is fixedly connected with two limiting plates, and the spacing between the limiting plates located on the same roller is equal to the thickness of the guide frame. The limiting plates are in close contact with the adjacent guide frames. This design ensures the stable relative position between the roller and the guide frame, preventing excessive movement of the roller during adjustment.

[0007] The two rollers are fixedly connected with a synchronous rod, so that the two rollers can move synchronously, ensuring the synchronism and consistency when the angle of the support plate is adjusted.

[0008] The clamping assembly comprises a bidirectional screw rod rotatably connected to the middle part of the base, the middle part of the bidirectional screw rod is threadedly connected with two symmetrical clamping blocks, and the clamping blocks are slidably connected to the middle part of the base.

[0009] The top of each clamping block is arc-shaped, and a plurality of clamping blocks are fixedly connected to the inner arc surface of each clamping block.

[0010] The base is provided with a guide groove on each side of the top thereof, the clamping block is provided with a guide block fixedly connected to the bottom of each side thereof, and the bottom of the guide block is slidably connected to the adjacent guide groove.

[0011] The base is provided with a passive gear fixedly connected to the bottom thereof, the support plate is provided with a driving gear rotatably connected to the bottom thereof, the support plate is provided with a rotating motor fixedly connected to one side of the top thereof, and the output shaft of the rotating motor is fixedly connected to the bottom of the driving gear.

[0012] Compared with the prior art, the present application has at least one of the following beneficial technical effects:

[0013] 1. As the position of the roller is close to or away from the connecting part of the support table and the support plate, the support plate rotates around the hinge, thereby adjusting the angle of the top of the support plate, which makes the aviation accessory have more processing angles when being fixed by the clamping assembly, effectively improves the flexibility and adaptability of the clamp, and meets various complex processing requirements.

[0014] 2. When the clamping block moves, the guide block slides in the guide groove, ensuring the linearity and stability of the clamping block during movement. The transverse movement of the clamping block when clamping or releasing the accessory is prevented, and the accuracy and repeatability of the clamping action are ensured.

[0023] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the appendices of the embodiments of this utility model. Figures 1-4 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0024] like Figures 1-4 As shown: This embodiment provides a fixture for manufacturing and processing aviation parts, including a support platform 100 and an adjustment assembly 200. The top of the support platform 100 is inclined, and a support plate 101 is hinged to the higher side of the top of the support platform 100. A base 102 is fixedly connected to the middle of the support plate 101, and a clamping assembly 300 is provided on the top of the base 102. The adjustment assembly 200 includes two symmetrically distributed slide rails 201 fixedly connected to the top of the support platform 100. A screw 202 is rotatably connected to the middle of each slide rail 201. Each of the slides 203 is threadedly connected to the middle section. The bottom of each slide 203 is slidably connected to the adjacent slide rail 201. One end of each screw 202 is fixedly connected to a sprocket. The two sprockets are connected by a chain drive. A synchronous motor is fixedly connected to one side of the support platform 100. The output shaft of the synchronous motor is fixedly connected to the middle of the adjacent sprocket. Rollers 204 are fixedly connected to the top of each slide 203. Multiple guide frames 205 are fixedly connected to the bottom of the support plate 101. The middle of each roller 204 is slidably connected to the middle of the adjacent guide frame 205.

[0025] When in use, by controlling the synchronous motor to operate, the adjacent sprocket drives the two sprockets to rotate synchronously through the chain, and the two sprockels drive the slider 203 to move synchronously along the slide rail 201, and the position of the roller 204 changes in the guide frame 205. As the position of the roller 204 approaches or moves away from the connection between the support table 100 and the support plate 101, the support plate 101 rotates around the hinge, thereby adjusting the angle of the top of the support plate 101. This allows the aircraft parts to have more processing angles when fixed by the clamping assembly 300, effectively improving the flexibility and adaptability of the clamp, and meeting various complex processing requirements.

[0026] The limiting plate 206 is as shown in Figure 4

[0027] The middle part of the roller 204 is fixedly connected with two limiting plates 206, and the spacing between the limiting plates 206 of the same roller 204 is equal to the thickness of the guide frame 205. The limiting plate 206 is in close contact with the adjacent guide frame 205.

[0028] The limiting plate 206 can keep the relative position between the roller 204 and the guide frame 205 stable, prevent the roller 204 from moving excessively during adjustment, and ensure the accuracy and stability of the angle adjustment of the support plate 101.

[0029] The synchronous rod 207 is as shown in Figure 1 , 3 , 4,

[0030] The synchronous rod 207 is fixedly connected between the rollers 204.

[0031] The synchronous rod 207 enables the two rollers 204 to move synchronously, ensuring the synchronization and consistency when adjusting the angle of the support plate 101. It avoids the inclination or unevenness of the support plate 101 caused by the asynchronous movement of the roller 204, thereby ensuring the stability and precision of the aircraft parts during processing.

[0032] The bidirectional screw rod 301 is as shown in Figure 1 , 2 ,

[0033] The clamping assembly 300 comprises a bidirectional screw rod 301 rotatably connected to the middle part of the base 102. The middle part of the bidirectional screw rod 301 is threadedly connected with two symmetrically distributed clamping blocks 302. The clamping blocks 302 are slidably connected with the middle part of the base 102. One side of the base 102 is fixedly connected with a clamping motor. The output shaft of the clamping motor is fixedly connected to the middle part of one end of the bidirectional screw rod 301.

[0034] ​When clamping the aviation accessory, the synchronous bidirectional movement of the clamping block 302 can be realized by controlling the clamping motor, so as to realize the clamping and loosening of the aviation accessory. When the clamping motor is started, the output shaft drives the bidirectional screw rod 301 to rotate, and due to the thread characteristics of the bidirectional screw rod 301, the clamping block 302 moves axially along the bidirectional screw rod 301. If the accessory needs to be clamped, the clamping block 302 will move towards the center until it contacts the accessory and exerts sufficient clamping force. If the accessory needs to be loosened, the clamping block 302 will move in the opposite direction, away from the accessory, to achieve loosening operation.

[0035] The clamping block 302 is shown in Figure 1 , 2 ,

[0036] The top of the clamping block 302 is arc-shaped, and the inner arc surface of the clamping block 302 faces the middle part of the base 102. A plurality of clamping blocks 303 are fixedly connected to the middle part of the inner arc surface of the clamping block 302.

[0037] The arc-shaped clamping block 302 can better adapt to and clamp aviation accessories of different shapes, and the inner arc surface of the clamping block 302 can ensure that the accessory is firmly fixed between the clamping block 302 and the base 102 during clamping. The clamping block 303 can form more contact points with the surface of the accessory, further enhancing the stability and safety of clamping.

[0038] The guide block 104 is shown in Figure 1 , 2 ,

[0039] The base 102 is provided with a guide groove 103 on both sides of the top, and the clamping block 302 is fixedly connected with a guide block 104 on both sides of the bottom. The bottom of the guide block 104 is slidably connected with the adjacent guide groove 103.

[0040] When the clamping block 302 moves, the guide block 104 slides in the guide groove 103, ensuring the linearity and stability of the clamping block 302 during movement. It prevents the clamping block 302 from moving horizontally when clamping or loosening the accessory, ensuring the accuracy and repeatability of the clamping action.

[0041] The passive gear 105 is shown in Figure 4 ,

[0042] The base 102 is fixedly connected with a passive gear 105, and the bottom of the support plate 101 is rotatably connected with a driving gear 106. The top side of the support plate 101 is fixedly connected with a rotating motor 107, and the height of the rotating motor 107 is lower than the height of the base 102. The output shaft of the rotating motor 107 is fixedly connected with the bottom of the driving gear 106.

[0043] The rotation of the rotating motor 107 can drive the driving gear 106 to rotate, and then the driven gear 105 is synchronously rotated through gear transmission, the base 102 is rotated on the relative horizontal plane of the support plate 101, and the aviation accessory can obtain more processing angles, so that the diversified processing requirements can be met. The height of the rotating motor 107 is lower than the height of the base 102, and such a layout helps to reduce the overall height of the clamp, so that the clamp is more compact and suitable for use in a processing environment with limited space. Meanwhile, the layout is also conducive to reducing the influence of the rotating motor 107 on the operation line of sight and improving the operation convenience.

[0044] In addition, it should be further pointed out that, in the description of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connection" should be understood in a broad sense, for example, can be fixed connection, can also be detachable connection, or integral connection, can be mechanical connection, can also be electrical connection, can be directly connected, can also be indirectly connected through an intermediate medium, can be the communication inside two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0045] The above is the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements and refinements can be made, which should also be considered as the protection scope of the present application.
