Description

Technical Field

[0001] This utility model relates to the technical field of quick-change milling cutter devices, specifically a quick-change device for contour milling cutters for processing curved surfaces of solid wood furniture. Background Technology

[0002] The quick-change profile milling cutter device for machining curved surfaces of solid wood furniture is a device used in the manufacturing process of solid wood furniture to quickly change profile milling cutters when machining curved surfaces. Solid wood furniture has a variety of curved surface shapes, and different curved surfaces require different shaped milling cutters for machining. Therefore, it may be necessary to frequently change milling cutters when machining curved surfaces of solid wood furniture.

[0003] Current technology requires operators to use two wrenches when changing milling cutters. One wrench holds the milling cutter's spindle, and the other wrench holds and rotates the locking nut to loosen the nut and release the cutter. A new cutter is then installed and the wrench is re-clamped. This method forces operators to use only one hand for each wrench, impacting milling cutter replacement efficiency. Furthermore, most milling cutters are made of brittle materials, and without proper clamping protection during replacement, they are prone to falling and damage, increasing furniture processing costs. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a quick-change device for profile milling cutters in the processing of curved surfaces of solid wood furniture. It has the advantages of high milling cutter replacement efficiency and good protective performance, thus solving the problems mentioned in the background technology.

[0005] This utility model provides the following technical solution: a quick-change device for contour milling cutters for processing curved surfaces of solid wood furniture, including a fixing mechanism. The fixing mechanism internally holds a milling cutter seat. A milling cutter shaft is rotatably connected to the lower end face of the milling cutter seat. A milling cutter body is snapped onto the lower end face of the milling cutter shaft. A locking nut is threaded onto the lower end face of the milling cutter shaft. A height adjustment mechanism is slidably connected to the front end face of the fixing mechanism. Two clamping mechanisms are fixedly installed on the upper end face of the height adjustment mechanism.

[0006] As a preferred technical solution of this utility model, the fixing mechanism includes a first fixing plate and a second fixing plate. Multiple first elastic blocks are fixedly installed on the inner sides of the first fixing plate and the second fixing plate. Two bolts are threadedly connected between the first fixing plate and the second fixing plate, and an adjusting nut is threadedly connected to one side of each bolt.

[0007] As a preferred technical solution of this utility model, a sliding groove is provided on the front end face of the first fixing plate, a fixing wrench is fixedly installed on the front end face of the first fixing plate, and a gripping handle is fixedly installed on the rear end face of the first fixing plate.

[0008] As a preferred embodiment of the present invention, the clamping mechanism includes a connecting plate, and a telescopic rod is fixedly installed on one side of the connecting plate.

[0009] As a preferred embodiment of this utility model, a clamping block is fixedly installed on one side of the telescopic rod, and a second elastic block is fixedly installed on one side of the clamping block.

[0010] As a preferred embodiment of this utility model, the height adjustment mechanism includes a support plate, a slider is fixedly installed on the rear end face of the support plate, a threaded rod is threadedly connected to the upper end face of the slider, and a rotating handle is fixedly installed on the lower end face of the threaded rod.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This quick-change device for contour milling cutters used in the processing of curved surfaces of solid wood furniture uses a fixed mechanism to clamp the milling cutter holder with a first and second fixing plate. Tightening the adjusting nut fixes the quick-change device to the outside of the milling cutter to be replaced. At the same time, the fixing wrench engages and locks the milling cutter shaft. Afterwards, the operator can use both hands to use a wrench to remove the locking nut, thereby improving the efficiency of milling cutter replacement and the reliability of installation.

[0013] 2. This quick-change device for contour milling cutters for solid wood furniture curved surface processing uses a clamping mechanism and a height adjustment mechanism installed at the front end of the fixed mechanism. By rotating the handle, the height of the support plate can be adjusted, thereby changing the height of the clamping mechanism. This allows the clamping mechanism to better hold the milling cutter body, effectively preventing the milling cutter body from falling off and being damaged during disassembly, thus reducing costs.

[0020] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figures 1-5 A quick-change device for contour milling cutters for processing curved surfaces of solid wood furniture includes a fixing mechanism 1, a milling cutter seat 2 held inside the fixing mechanism 1, a milling cutter shaft 3 rotatably connected to the lower end face of the milling cutter seat 2, a milling cutter body 5 snapped onto the lower end face of the milling cutter shaft 3, a locking nut 4 threadedly connected to the lower end face of the milling cutter shaft 3, a height adjustment mechanism 7 slidably connected to the front end face of the fixing mechanism 1, and two clamping mechanisms 6 fixedly installed on the upper end face of the height adjustment mechanism 7.

[0022] In the above structure, the milling cutter holder 2 and the milling cutter shaft 3 are fixed by the fixing mechanism 1, so that the workers can use wrenches with both hands to disassemble the locking nut 4, thereby improving the efficiency of milling cutter replacement and the reliability of installation. The height adjustment mechanism 7 and the clamping mechanism 6 clamp and fix the milling cutter body 5, thereby preventing the milling cutter body 5 from falling and being damaged when the locking nut 4 is disassembled, thus reducing the cost of solid wood furniture processing.

[0023] In a preferred embodiment, the fixing mechanism 1 includes a first fixing plate 104 and a second fixing plate 107. Multiple first elastic blocks 101 are fixedly installed on the inner sides of the first fixing plate 104 and the second fixing plate 107. Two bolts 102 are threadedly connected between the first fixing plate 104 and the second fixing plate 107. An adjusting nut 106 is threadedly connected to one side of each bolt 102. A sliding groove 105 is opened on the front end face of the first fixing plate 104. A fixing wrench 108 is fixedly installed on the front end face of the first fixing plate 104. A grip handle 103 is fixedly installed on the rear end face of the first fixing plate 104.

[0024] In the above structure, by rotating the adjusting nut 106, the first fixing plate 104 and the second fixing plate 107 can clamp and fix the milling cutter holder 2, thereby fixing the quick-change device of the milling cutter on the outside of the milling cutter to be replaced. At the same time, the fixing wrench 108 will lock and fix the milling cutter shaft 3, thereby freeing the operator's hands and allowing the operator to use both hands to use the wrench to disassemble the locking nut 4, thereby improving the efficiency of milling cutter replacement and the reliability of installation.

[0025] In a preferred embodiment, the clamping mechanism 6 includes a connecting plate 601, a telescopic rod 602 is fixedly installed on one side of the connecting plate 601, a clamping block 603 is fixedly installed on one side of the telescopic rod 602, and a second elastic block 604 is fixedly installed on one side of the clamping block 603.

[0026] In the above structure, the distance between the two clamping blocks 603 is changed by the extension and retraction of the telescopic rod 602, so that the clamping blocks 603 can clamp and fix the milling cutter body 5 of different sizes. The second elastic block 604 can not only protect the milling cutter body 5, but also increase the friction between the clamping block 603 and the milling cutter body 5, preventing the milling cutter body 5 from falling off and being damaged during disassembly, thereby reducing the processing cost of solid wood furniture.

[0027] In a preferred embodiment, the height adjustment mechanism 7 includes a support plate 701, a slider 704 is fixedly installed on the rear end face of the support plate 701, a threaded rod 703 is threadedly connected to the upper end face of the slider 704, and a rotating handle 702 is fixedly installed on the lower end face of the threaded rod 703.

[0028] In the above structure, the height of the support plate 701 can be adjusted by rotating the handle 702, thereby changing the height between the two clamping mechanisms 6, so that the clamping mechanism 6 can better clamp and fix the milling cutter body 5.

[0029] The working principle is as follows: the quick-change device for the milling cutter is fixed to the outside of the milling cutter to be replaced by the first fixing plate 104 and the second fixing plate 107. At the same time, the internal fixing wrench 108 will lock and fix the milling cutter shaft 3, so that the operator can use both hands to use the wrench to disassemble the locking nut 4, thereby improving the efficiency and reliability of the milling cutter replacement. Before the milling cutter is replaced, the height adjustment mechanism 7 and the clamping mechanism 6 are used to clamp and fix the milling cutter body 5, which can effectively prevent the milling cutter from falling off and being damaged during the disassembly process, thereby reducing the processing cost of solid wood furniture.

[0030] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
