Description

Technical Field

[0001] This utility model relates to the field of aluminum alloy handle manufacturing technology, and in particular to a clamping device for thread processing of die-cast aluminum alloy handles. Background Technology

[0002] Refrigerator doors typically use aluminum alloy handles, which are formed by die casting and then surface treated. To facilitate installation, threaded holes are also made on the back of the handle for installation.

[0003] During mass production, machining the threaded holes of aluminum alloy handles requires quick clamping of the handles and effective positioning of the quick-clamped handles to meet machining needs. Existing clamping equipment requires removing the handle and turning it around after machining the threaded hole at one end, and then re-clamping it, which takes a lot of time and requires repeated positioning and installation, posing a risk of affecting the machining progress. Utility Model Content

[0004] This utility model addresses the deficiencies in the prior art by providing a clamping device for thread processing of die-cast aluminum alloy handles.

[0005] This utility model is achieved through the following technical solution:

[0006] A clamping device for thread processing of die-cast aluminum alloy handles includes a base assembly, a switching assembly, a pressure applying mechanism, and a handle. The switching assembly is clamped to the inner top of the base assembly, the pressure applying mechanism is fixedly disposed on the top of the switching assembly, and the handle is clamped to the top of the switching assembly. The base assembly includes a sliding seat, a clamping plate, a control knob, and a pressure block. The clamping plate is fixedly disposed on the inner side of one end of the sliding seat, the control knob is threadedly connected to one end of the sliding seat, and the pressure block is movably connected to the end of the control knob. The switching assembly includes a slider, a rotating shaft, a clamping block, and inserts. The slider is clamped to the bottom of the sliding seat, the rotating shaft is fixedly disposed on the top of the slider, the clamping block is movably connected to the rotating shaft, and the inserts are fixedly disposed on both ends of the slider.

[0007] In a preferred embodiment of the present invention, the pressure applying mechanism includes a mounting frame, a guide shaft, a pressure applying seat, a spring, and a pressure applying knob. The guide shaft is fixedly disposed on the inner side of the top of the mounting frame, the pressure applying seat and the spring are sleeved on the surface of the guide shaft, and the pressure applying knob is snapped onto the top of the mounting frame.

[0008] After the handle is positioned in the corresponding groove on the top of the card block, pressure can be applied to the top of the handle by controlling the pressure seat of the pressure device to move down, thereby effectively achieving limit fixation.

[0009] In a preferred embodiment of this utility model, the bottom of the pressure knob is movably connected to the top of the pressure seat. The bottom of the pressure knob is a round shaft structure, and its top is a threaded structure. The top of the mounting bracket is provided with a threaded hole that mates with it.

[0010] The cylindrical structure at the bottom of the pressure knob facilitates quick adjustment of the pressure seat position, while the threaded structure at the top facilitates fixing the pressure seat when it is pressed down.

[0011] In a preferred embodiment of this utility model, the bottom of the guide shaft is fixed to the top of the slider, and the spring is located between the pressure seat and the slider to ensure that when the pressure knob is released to apply pressure to the pressure seat, the spring can quickly move the pressure seat upward, which facilitates the disassembly and installation of the handle.

[0012] In a preferred embodiment of the present invention, the bottom of the slider is provided with a sliding block that cooperates with the sliding seat, and the bottom of the pressure block is provided with a sliding block that cooperates with the sliding seat.

[0013] In a preferred embodiment of this utility model, a slot for engaging with an insert is provided on the inner side of one end of the card plate.

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

[0015] This clamping equipment for machining threaded parts of aluminum alloy handle die castings is mainly used to process threaded holes for handle installation. After the handle is pressed and fixed, it can be quickly positioned to ensure the machining position. After the single-sided mounting hole is machined, the machining area can be quickly switched by rotation without repeated disassembly and clamping, effectively ensuring machining accuracy and improving machining efficiency.

The directional terms mentioned in this utility model, such as "up," "down," "front," "back," "left," "right," "top," and "bottom," are only for reference to the accompanying drawings. Therefore, the directional terms used are for the purpose of explaining and understanding this utility model, and not for limiting this utility model.

[0021] like Figure 1-3 The clamping device for thread processing of die-cast aluminum alloy handles shown includes a base assembly 1, a switching assembly 2, a pressure applying mechanism 3, and a handle 4. The switching assembly 2 is clamped on the inner side of the top of the base assembly 1, the pressure applying mechanism 3 is fixedly installed on the top of the switching assembly 2, and the handle 4 is clamped on the top of the switching assembly 2. The base assembly 1 includes a sliding seat 11, a clamping plate 12, a control knob 13, and a pressure block 14. The clamping plate 12 is fixedly installed on the inner side of one end of the sliding seat 11, the control knob 13 is threadedly connected to one end of the sliding seat 11, and the pressure block 14 is movably connected to the end of the control knob 13. The switching assembly 2 includes a slider 21, a rotating shaft 22, a clamping block 23, and an insert 24. The slider 21 is clamped on the bottom of the sliding seat 11, the rotating shaft 22 is fixedly installed on the top of the slider 21, the clamping block 23 is movably connected to the rotating shaft 22, and the insert 24 is fixedly installed on both ends of the slider 21.

[0022] Specifically, the pressure applying mechanism 3 includes a mounting frame 31, a guide shaft 32, a pressure applying seat 33, a spring 34, and a pressure applying knob 35. The guide shaft 32 is fixedly installed on the inner side of the top of the mounting frame 31. The pressure applying seat 33 and the spring 34 are sleeved on the surface of the guide shaft 32. The pressure applying knob 35 is snapped onto the top of the mounting frame 31. The bottom of the pressure applying knob 35 is movably connected to the top of the pressure applying seat 33. The bottom of the pressure applying knob 35 is a round shaft structure, and its top is a threaded structure. The top of the mounting frame 31 has a threaded hole that mates with it. The bottom of the guide shaft 32 is fixed to the top of the slider 21. The spring 34 is located between the pressure applying seat 33 and the slider 21. The bottom of the slider 21 is provided with a sliding block that mates with the sliding seat 11. The bottom of the pressure block 14 is provided with a sliding block that mates with the sliding seat 11. The inner side of one end of the clamping plate 12 has a slot that mates with the insert 24.

[0023] In this embodiment, the handle 4 is first secured to the top of the card block 23 according to the groove on the top of the card block 23. Then, the pressure knob 35 is pressed down, the pressure seat 33 is pressed down and the spring 34 is contracted. The pressure knob 35 is rotated so that its top threaded end is connected to the top threaded hole of the mounting bracket 31, ensuring the pressure seat 33 has a good effect on fixing the handle 4.

[0024] Furthermore, rotating the control knob 13 controls the pressure block 14 to push the sliding seat 11 forward until the insert 24 on the outer side of one end of the clamping block 23 is engaged in the slot on the inner side of one end of the clamping plate 12. One end of the handle is engaged in the slot at one end of the sliding seat 11, and the other end is engaged in the slot at the top of one end of the pressure block 14, thereby effectively clamping and fixing the handle 4 and effectively positioning it, which facilitates the processing of the mounting hole on one side. After processing is completed, rotating the control pressure block 14 backward will move the sliding seat 11 until the insert 24 is separated from the clamping plate 12. The clamping block 23 can then be rotated through the rotating shaft 22 to achieve the effect of switching the processing area. Rotating the control knob 13 again will push the sliding seat 11 forward to clamp and position it, thus realizing the processing of the threaded hole on the other end.
