Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mechanical processing, and in particular to a positioning fixture for processing aluminum alloy shells. Background Technology

[0002] Aluminum alloy housings are widely used in many fields, such as electronic device housings, automotive parts, and aerospace components. During machining operations on aluminum alloy housings, such as drilling, milling, and boring, positioning fixtures are required to ensure the positional accuracy and stability of the housing during the machining process.

[0003] However, current aluminum alloy housing machining positioning fixtures on the market have many shortcomings. On the one hand, some fixtures have low positioning accuracy, which cannot meet the requirements of high-precision machining processes, resulting in deviations in dimensional accuracy and geometric tolerances of the machined aluminum alloy housing, affecting the assembly performance and overall quality of the product. On the other hand, aluminum alloy housings cannot be cooled down quickly after cutting and grinding, making it inconvenient to remove them from the positioning fixture in a timely manner. Waiting for natural cooling is very time-consuming, affecting the machining efficiency of aluminum alloy housings. Therefore, a positioning fixture for machining aluminum alloy housings is provided. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a positioning fixture for machining aluminum alloy shells. By turning the second adjusting bolt with a wrench, two adjusting rods and two support rods can be moved, facilitating fine-tuning of the position of the aluminum alloy shell. By turning the first adjusting bolt, the fixed bottom pressure plate can be moved down to press the aluminum alloy shell in place. A third electric push rod pushes the L-shaped clamping plate down and clamps it on the upper side of the aluminum alloy shell, improving the stability of the aluminum alloy shell after fixing, thereby further improving the positioning accuracy of the aluminum alloy shell and effectively meeting the requirements of high-precision machining processes. Furthermore, a cooling fan can blow cold air onto the aluminum alloy shell to cool it down after machining, facilitating timely disassembly of the finished aluminum alloy shell and reducing waiting time, thus overcoming the shortcomings of existing technologies.

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

[0006] A positioning fixture for machining aluminum alloy shells includes a base plate. A lifting bracket is fixed to one side of the upper end of the base plate. An L-shaped mounting rod is installed on the lifting bracket. A strip-shaped hole is opened on the horizontal section of the L-shaped mounting rod. An I-beam adjusting block is slidably engaged at the strip-shaped hole. A first adjusting bolt is screwed onto the I-beam adjusting block. The lower end of the first adjusting bolt is rotatably connected to a fixed bottom pressure plate through a bearing. An L-shaped support is fixed to the upper end face of the base plate. An adjusting bracket and a cooling component are installed on the L-shaped support.

[0007] As a further embodiment of this utility model: a first electric push rod is connected to the top of one side of the I-shaped adjusting block, and one end of the first electric push rod is fixed to one side of the vertical section of the L-shaped mounting rod.

[0008] As a further improvement of this utility model: the adjusting bracket includes two support rods that are movably inserted into the bottom of the vertical section of the L-shaped support, and an adjusting rod is connected to one end of the two support rods away from the vertical section of the L-shaped support.

[0009] As a further embodiment of this utility model: a connecting block is fixed on one side of the upper surface of the horizontal section of the L-shaped support, and a second adjusting bolt is screwed onto the connecting block. One end of the second adjusting bolt is rotatably connected to one side of the adjusting rod through a bearing.

[0010] As a further improvement of this utility model: the cooling component includes two mounting holes opened on the vertical section of the L-shaped support, and a cooling fan is installed in each of the two mounting holes.

[0011] As a further improvement of this utility model, two limiting rods are symmetrically fixed to the upper end of the horizontal section of the adjusting rod.

[0013] As a further embodiment of this utility model: a third electric push rod is fixed to the lower end face of the lifting rod and the side near the L-shaped mounting rod, and the lower end of the third electric push rod is connected to an L-shaped clamping plate.

[0014] The beneficial effects of this utility model are as follows:

By turning the first adjusting bolt, the fixed bottom pressure plate can be moved down to press the aluminum alloy shell in place. The third electric push rod pushes the L-shaped clamping plate down and clamps it on the upper side of the aluminum alloy shell, improving the stability of the aluminum alloy shell after it is fixed, thereby further improving the positioning accuracy of the aluminum alloy shell and effectively meeting the requirements of high-precision processing.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Example 1, referring to Figure 1-4 A positioning fixture for processing aluminum alloy shells includes a base plate 1. A lifting bracket is fixed to one side of the upper end of the base plate 1. An L-shaped mounting rod 13 is installed on the lifting bracket. A strip hole 21 is opened on the horizontal section of the L-shaped mounting rod 13. An I-beam adjusting block 20 is slidably engaged at the strip hole 21. A first adjusting bolt 18 is screwed onto the I-beam adjusting block 20. The lower end of the first adjusting bolt 18 is rotatably connected to a fixed bottom pressure plate 12 through a bearing. An L-shaped support 4 is fixed to the upper end face of the base plate 1. An adjusting bracket and a cooling component are installed on the L-shaped support 4.

[0023] The top of one side of the I-beam adjusting block 20 is connected to a first electric push rod 19, and one end of the first electric push rod 19 is fixed to one side of the vertical section of the L-shaped mounting rod 13.

[0024] The adjusting bracket includes two support rods 16 that are movably inserted into the bottom of the vertical section of the L-shaped support 4. The ends of the two support rods 16 away from the vertical section of the L-shaped support 4 are connected to adjusting rods 5. The upper end of the horizontal section of the adjusting rods 5 is symmetrically fixed with two limit stops 6.

[0025] A connecting block 14 is fixed on one side of the upper end face of the horizontal section of the L-shaped support 4. A second adjusting bolt 15 is screwed onto the connecting block 14. One end of the second adjusting bolt 15 is rotatably connected to one side of the adjusting rod 5 through a bearing.

[0026] The cooling component includes two mounting holes on the vertical section of the L-shaped support 4, and a cooling fan 17 is installed in each of the two mounting holes.

[0027] The aluminum alloy shell is placed on two support rods 16. By turning the second adjusting bolt 15 with a wrench, the two adjusting rods 5 and the two support rods 16 can be moved, which facilitates fine adjustment of the position of the aluminum alloy shell. By sliding the I-beam adjusting block 20 along the strip hole 21, the position of the first adjusting bolt 18 can be adjusted. By turning the first adjusting bolt 18, the fixed bottom plate 12 can be moved down to press down the aluminum alloy shell, thereby fixing the aluminum alloy shell and facilitating the processing of the aluminum alloy shell. The cooling fan 17 can blow cold air onto the aluminum alloy shell to cool it down after processing, which facilitates the timely disassembly of the finished aluminum alloy shell and reduces waiting time.
