[0001] The utility model relates to the technical field of aluminum fitting processing and clamping, in particular to a clamping fixture for aluminum fitting processing. Background Technique

[0002] Aluminum fitting processing refers to processing aluminum materials into fittings with specific shapes and sizes through various machining technologies to meet the needs of industries such as industry, construction, automotive, and electronics. Due to the advantages of aluminum materials such as light weight, high strength, and corrosion resistance, aluminum fittings are widely used in modern manufacturing. In order to ensure the fixed position and stability of aluminum fittings during processing, a clamping fixture for aluminum fitting processing is required, thereby improving processing accuracy and consistency and avoiding dimensional deviations and shape errors caused by workpiece movement.

[0003] During the use of traditional clamping fixtures for aluminum fitting processing, the aluminum fittings are placed on the fixture and accurately positioned through clamping devices. The clamping device makes the surrounding clamping blocks move uniformly through a threaded rod, and can apply uniform pressure during operation to ensure that the fittings do not move or vibrate. After clamping, the fixture fixes the workpiece on the machine tool to ensure that the position and angle of the workpiece remain unchanged during processing.

[0004] However, during the clamping process of aluminum fittings, the problem that operators need to cooperate with tools to disassemble or install parts on the fixture has not been solved, so the processing efficiency of aluminum fittings is low, affecting the production efficiency of aluminum fitting processing. Content of the Utility Model

[0005] In order to make up for the above deficiencies, the utility model provides a clamping fixture for aluminum fitting processing, aiming to improve the problem that operators need to cooperate with tools to disassemble or install parts on the fixture, so the processing efficiency of aluminum fittings is low.

[0006] To achieve the above object, the utility model adopts the following technical scheme: A clamping fixture for aluminum fitting processing, including a base, a first support column is fixedly connected to the top of the base, a support plate is arranged on one side of the first support column, a connecting column is fixedly connected to the top of the support plate, a top plate is fixedly connected to one end of the connecting column, an electric push rod is arranged at the bottom of the top plate, a cross bracket is fixedly connected to the output end of the electric push rod, a limiting component is arranged at the bottom of the top plate, the limiting component is used to limit the cross bracket, a connecting rod is rotatably connected inside the cross bracket, one end of the connecting rod is rotatably connected to an L-shaped support rod, the outer wall of the L-shaped support rod is slidably connected inside the top plate, a clamping block is fixedly connected to the top of the L-shaped support rod, and an anti-slip strip is fixedly connected to one side of the clamping block.

[0009] As a further description of the above technical solution:

[0010] A second support column is fixedly connected to the outer wall of the support plate, and a first sleeve is fixedly connected inside the second support column.

[0011] As a further description of the above technical solution:

[0012] A first limiting block is fixedly connected inside the first sleeve, and a first limiting groove is formed inside the first sleeve.

[0013] As a further description of the above technical solution:

[0014] A second sleeve is fixedly connected to the top of the first support column. The outer wall of the second sleeve is rotatably connected inside the first limiting groove, and a second limiting groove is formed inside the inner wall of the second sleeve.

[0031] Specifically, when fixing the aluminum fitting, only need to place the aluminum fitting on the top plate 5, and then retract the output end of the electric push rod 10 to drive the cross bracket 8 to descend. The cross bracket 8 is limited by the limiting column 9, and at the same time, the connecting rod 7 drives the L-shaped support rod 6 to move towards the center direction inside the top plate 5, so as to drive the clamping block 11 to clamp and fix the aluminum fitting. An anti-slip strip 12 is installed between the clamping block 11 and the aluminum fitting to ensure that the aluminum fitting will not slide during the clamping process, thus realizing quick fixation. When it is necessary to remove the aluminum fitting, only need to extend the output end of the electric push rod 10 to drive the clamping block 11 to release the aluminum fitting.

[0032] Referring to Figure 3 , a second support column 13 is fixedly connected to the outer wall of the support plate 3, a first sleeve 14 is fixedly connected inside the second support column 13, a first limiting block 16 is fixedly connected inside the first sleeve 14, a first limiting groove 15 is opened inside the first sleeve 14, a second sleeve 17 is fixedly connected to the top of the first support column 2, the outer wall of the second sleeve 17 is rotatably connected inside the first limiting groove 15, a second limiting groove 18 is opened on the inner wall of the second sleeve 17, a limiting plate 20 is slidably connected inside the first sleeve 14, a third limiting groove 21 is opened inside the limiting plate 20, the limiting plate 20 is slidably connected to the outer wall of the first limiting block 16 through the third limiting groove 21, a locking shaft 19 is fixedly connected to one side of the limiting plate 20, a second limiting block 22 is fixedly connected to the outer wall of the locking shaft 19, the outer wall of the locking shaft 19 passes through the inside of the second sleeve 17, and the outer wall of the second limiting block 22 is slidably connected inside the second limiting groove 18. A spring 23 is disposed inside the first sleeve 14, one end of the spring 23 is fixedly connected to the other side of the limiting plate 20, and the other end of the spring 23 is fixedly connected to the inside of the first sleeve 14;

[0033] Specifically, when adjusting the inclination angle of the top plate 5 according to different usage environments, the locking shaft 19 needs to be pressed to squeeze the spring 23 so that it retracts into the inner part of the first sleeve 14. Then, rotate the second support column 13 to adjust the inclination angle of the top plate 5. After the adjustment is in place, release the locking shaft 19. The locking shaft 19 will reset under the tension of the spring 23, and the locking shaft 19 will be pushed back to its original position by pushing the limiting plate 20. The limiting plate 20 is limited by sliding on the outer wall of the first limiting block 16 in the first sleeve 14 through the third limiting groove 21. At the same time, the second limiting block 22 on the outer wall of the locking shaft 19 will slide into the second limiting groove 18 to lock with the first sleeve 14, thereby fixing the angle of the support plate 3.

[0034] Working principle: When using the clamping fixture for aluminum fitting processing, first, when adjusting the inclination angle of the top plate 5 according to different usage environments, press the locking shaft 19 to squeeze and compress the spring 23 into the inner part of the first sleeve 14. Subsequently, rotate the second support column 13 to adjust the inclination angle of the top plate 5. After it is in place, release the locking shaft 19. The locking shaft 19 will reset under the tension of the spring 23 and drive the locking shaft 19 to reset by pushing the limiting plate 20. The limiting plate 20 is limited by sliding on the outer wall of the first limiting block 16 in the first sleeve 14 through the third limiting groove 21. At the same time, the second limiting block 22 on the outer wall of the locking shaft 19 slides into the second limiting groove 18 to lock with the first sleeve 14, and the angle of the support plate 3 can be fixed. Subsequently, when fixing the aluminum fitting, just place the aluminum fitting on the top plate 5. Then, the output end of the electric push rod 10 retracts to drive the cross bracket 8 to descend. The cross bracket 8 is limited by the limiting column 9, and the cross bracket 8 drives the L-shaped support rod 6 to be limited inside the top plate 5 through the connecting rod 7, so that the L-shaped support rod 6 moves towards the center of the top plate 5, thereby driving the clamping block 11 to clamp and fix the aluminum fitting. The anti-slip strip 12 is used for anti-slip between the clamping block 11 and the aluminum fitting, and thus the aluminum fitting can be quickly fixed. When unloading, the output end of the electric push rod 10 extends to drive the clamping block 11 to release the aluminum fitting.
