Description

Technical Field

[0001] This utility model relates to the field of machining technology, and in particular to a fixture for machining internally threaded aluminum tubes that is easy to fix. Background Technology

[0002] Internally threaded aluminum tubes are widely used in automotive heat exchangers, air conditioning refrigeration systems, aerospace hydraulic lines, and other fields, and their processing accuracy directly affects product performance. However, due to the special properties of aluminum, such as low elastic modulus, easy elastic deformation, and easy surface scratches, traditional fixtures are difficult to meet processing requirements.

[0003] Existing internal thread aluminum tube processing fixtures are not adaptable to aluminum tubes of different sizes, requiring fixture replacement for different sizes, resulting in low efficiency. At the same time, the fixture is in direct contact with the aluminum tube, which can easily scratch the surface of the aluminum tube. Furthermore, if the clamping force of the fixture is too great, it can cause deformation of the aluminum tube, resulting in material waste. Utility Model Content

[0004] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a convenient fixing fixture for internally threaded aluminum tubes, thereby further improving the fixture's adaptability to aluminum tubes.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A fixture for machining internally threaded aluminum tubes that is easy to fix includes a hydraulic cylinder, a connecting rod fixedly provided at the output end of the hydraulic cylinder, a connecting block rotatably provided on the outside of the connecting rod, an upper clamping component provided at the bottom end of the connecting block, and a lower clamping component provided at the bottom of the upper clamping component;

[0007] Both the upper clamping component and the lower clamping component are provided with tube adaptation components on their inner sides. Each tube adaptation component includes multiple hollow rods, which are respectively fixedly connected to the upper clamping component and the lower clamping component. A spring is fixedly provided on the inner side of each hollow rod, and a long rod is fixedly provided at one end of each spring. The long rod is slidably connected to the hollow rod, and a rubber pad is fixedly provided at one end of the long rod.

[0008] Preferably, the upper clamping component includes a first clamp, the surface of which has a mounting hole, and a square locking block is fixed inside the mounting hole.

[0009] Preferably, both ends of the square card block extend to the outside of the mounting hole, the upper end of the square card block is fixedly connected to the connecting block, and the lower end of the square card block is rotatably provided with a locking strip.

[0010] Preferably, the lower clamping component includes a second clamp, which is rotatably connected to the first clamp. The surface of the second clamp is provided with a square slot, and the inner side of the square slot is provided with a through hole. The shape of the through hole is consistent with that of the snap-fit ​​strip, and a fixing block is provided below the through hole.

[0011] Preferably, the surface of the fixing block is provided with a fixing groove, the shape of the fixing groove is consistent with the snap-fit ​​strip, the fixing block is rotatably connected to the second clamp, the bottom of the fixing block is provided with a fixing rod, and the bottom end of the fixing rod is provided with a knob.

[0012] This utility model has the following beneficial effects:

[0013] 1. Easy to fix: Simply place the aluminum tube inside the second clamp and use the hydraulic cylinder to push the upper clamp component to make it fit with the lower clamp component. At this time, the snap-fit ​​strip should be in the fixing groove opened on the surface of the fixing block. By rotating the knob, the aluminum tube can be fixed, which is convenient, quick and easy to operate.

[0014] II. Applicable to multiple sizes: When selecting aluminum tubes of different diameters, simply place the aluminum tube inside the second clamp and fix the first clamp to the second clamp. Since both the first clamp and the second clamp are equipped with tube adaptation components, during the downward movement of the first clamp, the upper tube adaptation component contacts the aluminum tube. In order to adapt to the diameter of the aluminum tube, during the downward pressing process, the long rod will squeeze the spring in the opposite direction to adapt to the diameter of the aluminum tube by contracting inward.

[0015] 3. Avoid direct contact: When fixing the aluminum tube, the first part that comes into contact is the rubber pad at the front end of the long rod. The rubber pad is soft and will not scratch the surface of the aluminum tube. After it is completely fixed, only the rubber pad comes into contact with the aluminum tube. At the same time, the device is elastic and will not apply too much force to the aluminum tube while adapting to it, so that the aluminum tube will not be deformed. Attached Figure Description

[0022] 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 skilled in the art without creative effort are within the protection scope of the present utility model.

[0023] according to Figures 1 to 4 As shown, a fixture for processing internally threaded aluminum tubes that is easy to fix includes a hydraulic cylinder 1, a connecting rod 2 fixedly provided at the output end of the hydraulic cylinder 1, a connecting block 3 rotatably provided on the outside of the connecting rod 2, an upper clamping component 4 provided at the bottom end of the connecting block 3, and a lower clamping component 5 provided at the bottom of the upper clamping component 4.

[0024] Both the upper clamping component 4 and the lower clamping component 5 are provided with tube adaptation components 6 on their inner sides. The tube adaptation component 6 includes multiple hollow rods 61, which are fixedly connected to the upper clamping component 4 and the lower clamping component 5 respectively. A spring 62 is fixedly provided on the inner side of the hollow rod 61. A long rod 63 is fixedly provided at one end of the spring 62. The long rod 63 is slidably connected to the hollow rod 61. A rubber pad 64 is fixedly provided at one end of the long rod 63.

[0025] Hydraulic cylinder 1 can be fixed in a suitable position. As the main power source of the device, hydraulic cylinder 1 plays a pushing role in fixing the upper clamping component 4 and the lower clamping component 5.

[0026] The connecting rod 2 fixed at the output end of the hydraulic cylinder 1 is used to connect the connecting block 3. When the hydraulic cylinder 1 outputs thrust in its output direction, the upper clamping component 4 moves downward in an arc around the axis of its rotational connection with the lower clamping component 5. Since the connecting block 3 is fixed to the square clamping block 43 and the square clamping block 43 is fixed to the first clamping device 41, when the first clamping device 41 moves downward in an arc, the connecting block 3 moves in an arc at the same time. Since the connecting block 3 and the connecting rod 2 are rotatable, when the hydraulic cylinder 1 outputs thrust in its output direction, it will not be unable to move, but will convert the linear motion into an arc motion.

[0027] Since the through holes 53 and fixing grooves 55 on the second clamp 51 and fixing block 54 are identical in shape to the snap-fit ​​strip 44, when the first clamp 41 and the second clamp 51 are fully fitted together, the snap-fit ​​strip 44 falls right into the fixing groove 55. At this time, the operator rotates the knob 57, which drives the fixing rod 56 to rotate and simultaneously drives the fixing block 54 to rotate. Because the snap-fit ​​strip 44 is rotatably connected to the square snap-fit ​​block 43, the snap-fit ​​strip 44 rotates accordingly, thus achieving the fixation of the first clamp 41 and the second clamp 51. At the same time, because the square snap-fit ​​block 43 is provided, and the second clamp 51 has a square snap-fit ​​groove 52, the square snap-fit ​​block 43 snaps into the square snap-fit ​​groove 52, causing the control device to shift during fixation.

[0028] After the first clamp 41 and the second clamp 51 are fully closed, the aluminum tube is fixed between the two clamps. Because the device is elastic, the aluminum tube is clamped between the tube adapting member 6. At this time, the aluminum tube exerts a compressive force on the tube adapting member 6, and the tube adapting member 6 also exerts a compressive force on the aluminum tube. Therefore, due to the elastic effect of the spring 62, the device can firmly fix the aluminum tube between the clamps, and has a good fixing effect on the aluminum tube.

[0029] When processing vibration causes axial displacement of the aluminum tube, the release of the elastic potential energy of spring 62 allows the arc-shaped pressure plate to automatically follow the movement of the tube, maintaining a constant contact area and avoiding local stress concentration.

[0030] When the first clamp 41 and the second clamp 51 fix the aluminum tube, in order to prevent damage to the aluminum tube and deformation of the aluminum tube, resulting in loss, rubber pads 64 are set at the top of the long rod 63. At the same time, the device is elastic, so the long rod 63 can be protected by the elasticity of the device and the rubber pads 64.

[0031] The above are merely specific embodiments of this utility model, but the technical features of this utility model are not limited thereto. Any simple changes, equivalent substitutions, or modifications made based on this utility model to solve essentially the same technical problems and achieve essentially the same technical effects are all covered within the protection scope of this utility model.
