Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy frame processing technology, specifically, to a fixture for processing aluminum alloy frames for refrigerator drawers. Background Technology

[0002] To facilitate assembly, the aluminum alloy frames of refrigerator drawers generally need to be milled with grooves or holes. However, existing fixtures require calibration of the positioning reference after each clamping of the aluminum alloy frame to reduce the form and position errors during processing. However, the above calibration operation is time-consuming and has low production efficiency in mass production. Utility Model Content

[0003] This utility model provides a processing fixture for aluminum alloy frames of refrigerator drawers, which can overcome some or all the defects of the prior art.

[0004] A refrigerator drawer aluminum alloy frame processing fixture according to the present invention includes a base plate. At least two clamping mechanisms are spaced apart along the length direction on one side of the base plate. Each clamping mechanism includes a mounting plate fixedly engaged with the base plate. At least one mounting groove is formed on the side of the mounting plate away from the base plate. The mounting groove is used to place the aluminum alloy frame to be processed. A pressure plate is provided on the side of the mounting plate away from the base plate. The pressure plate is used to abut against the aluminum alloy frame. A first driving part is provided on the side of the base plate away from the mounting plate. The first driving part is used to drive the pressure plate to approach and move away from the aluminum alloy frame. A limiting mechanism is provided on the base plate along the extension direction of the mounting groove. The limiting mechanism includes a limiting block that moves along the height direction. The limiting block is used to abut against one end of the aluminum alloy frame when installing the aluminum alloy frame to be processed. The limiting mechanism also includes a second driving part. The second driving part is used to drive the limiting block to approach and move away from the base plate.

[0005] Preferably, the drive unit includes a first cylinder with a retractable first piston rod. The end of the first piston rod forms a mating shaft with a square cross-section. A through square hole is formed at the pressure plate, and a screw is provided at the square hole for threaded connection with the mating shaft through the square hole.

[0006] Preferably, a mating boss is formed on the side of the first cylinder near the base plate, a first mating hole is formed on the base plate, and a second mating hole is formed on the mounting plate. The mating boss passes through the first and second mating holes.

[0007] Preferably, the second drive unit includes a second cylinder located on the side of the base plate away from the mounting plate, the second cylinder having a retractable second piston rod, the end of the second piston rod being fixedly engaged with a limiting block.

[0008] Preferably, the base plate has two side plates spaced apart on the side away from the mounting plate.

[0009] Beneficial effects: The mounting slot can hold the aluminum alloy frame, and the first driving unit can drive the pressure plate to press the aluminum alloy frame, thereby achieving the clamping of the aluminum alloy frame. The limiting block can abut against one end of the aluminum alloy frame, thereby enabling the aluminum alloy frame to be accurately positioned. The limiting block can move closer to or further away from the base plate, so it can separate from the aluminum alloy frame after positioning, thus avoiding interference with the cutting tool during the processing of the aluminum alloy frame. In this utility model, the aluminum alloy frame is positioned by abutting against the limiting block during clamping, eliminating the need for measurement, thus significantly improving production efficiency.

[0014] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.

[0015] Seen in Figure 1-4 This embodiment provides a refrigerator drawer aluminum alloy frame processing fixture, which includes a base plate 1. At least two clamping mechanisms 2 are provided at intervals along the length direction on one side of the base plate 1. The clamping mechanism 2 includes a mounting plate 21 fixedly engaged with the base plate 1. At least one mounting groove 211 is formed on the side of the mounting plate 21 away from the base plate 1. The mounting groove 211 is used to place the aluminum alloy frame to be processed. A pressure plate 22 is provided on the side of the mounting plate 21 away from the base plate 1. The pressure plate 22 is used to abut against the aluminum alloy frame. A first driving part 3 is provided on the side of the base plate 1 away from the mounting plate 21. The first driving part 3 is used to drive the pressure plate 22 to approach and move away from the aluminum alloy frame. A limiting mechanism 4 is provided on the base plate 1 along the extension direction of the mounting groove 211. The limiting mechanism 4 includes a limiting block 41 that moves along the height direction. The limiting block 41 is used to abut against one end of the aluminum alloy frame when installing the aluminum alloy frame to be processed. The limiting mechanism 4 also includes a second driving part 5. The second driving part 5 is used to drive the limiting block 41 to approach and move away from the base plate 1.

[0016] According to the solution provided in this embodiment, the mounting slot 211 can hold the aluminum alloy frame, the first driving part 3 can drive the pressure plate 22 to press the aluminum alloy frame, thereby realizing the clamping of the aluminum alloy frame, the limiting block 41 can abut against one end of the aluminum alloy frame, thereby enabling the aluminum alloy frame to be accurately positioned, the limiting block 41 can approach and move away from the base plate 1, so it can separate from the aluminum alloy frame after positioning, thereby avoiding interference with the tool when processing the aluminum alloy frame.

[0017] With the above structure, the aluminum alloy frame is positioned by abutting against the limiting block 41 during clamping, eliminating the need for measurement and thus improving production efficiency.

[0018] Furthermore, the drive unit includes a first cylinder 31, the first cylinder 31 having a telescopic first piston rod 32, the end of the first piston rod 32 forming a mating shaft 321 with a square cross-section, a corresponding through square hole 221 formed at the pressure plate 22, a screw provided at the square hole 221, the screw being used to pass through the square hole 221 and threadedly connect with the mating shaft 321.

[0019] Specifically, the first cylinder 31 can drive the pressure plate 22 to approach and move away from the mounting plate 21, thereby achieving the clamping and releasing of the aluminum alloy frame. In conjunction with the shaft 321 and the square hole 221, the pressure plate 22 can be prevented from deflecting relative to the first piston rod 32, thus achieving a better stable clamping of the aluminum alloy frame by the pressure plate 22.

[0020] Among them, a mating boss 311 is formed on the side of the first cylinder 31 near the base plate 1, a first mating hole 11 is formed on the base plate 1, and a second mating hole 212 is formed on the mounting plate 21. The mating boss 311 passes through the first mating hole 11 and the second mating hole 212, which facilitates the installation of the first cylinder 31.

[0021] Furthermore, the second drive unit 5 includes a second cylinder 51 located on the side of the base plate 1 away from the mounting plate 21. The second cylinder 51 has a telescopic second piston rod 52, the end of which is fixedly engaged with the limiting block 41.

[0022] Specifically, the second cylinder 51 can drive the second piston rod 52 to extend and retract, thereby driving the limiting block 41 to move closer to and away from the base plate 1. This enables the limiting block 41 to move away from the base plate 1 during the installation of the aluminum alloy frame, facilitating the end of the aluminum alloy frame to abut against the limiting block 41. After positioning is completed, the limiting block 41 is driven closer to the base plate 1, thereby avoiding interference with the cutting tool.

[0023] Furthermore, the base plate 1 has two side plates 6 spaced apart on the side away from the mounting plate 21.

[0024] Specifically, the side plate 6 can lift the base plate 1, thereby facilitating the installation of the first cylinder 31 and the second cylinder 51.

[0025] Working principle:

[0026] When clamping the aluminum alloy frame, the second cylinder 51 drives the limiting block 41 away from the base plate 1, placing the aluminum alloy frame to be processed into the mounting groove 211, with one end abutting against the limiting block 41. The first cylinder 31 drives the pressure block to abut against the aluminum alloy frame to be processed. Then, the second cylinder 51 drives the limiting block 41 closer to the base plate 1, separating the limiting block 41 from the aluminum alloy frame to be processed, thus completing the clamping of the aluminum alloy frame to be processed. After that, the aluminum alloy frame can be CNC machined.

[0027] After processing, the first cylinder 31 drives the pressure block away from the mounting plate 21, causing the pressure block to separate from the processed aluminum alloy frame, so that the user can remove the processed aluminum alloy frame.
