[0023] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0024] The utility model provides a chamfering clamping tool for metal decorative strips of luggage, including a workbench 1, a fixture 2, a plurality of first positioning columns 3 and a plurality of second positioning columns 4, the fixture 2 includes a first fixture 21, a second fixture 22, a third fixture 23, a fourth fixture 24 and a fifth fixture 25, the first fixture 21 and the second fixture 22 are respectively arranged at the two ends of the left half of the workbench 1, the third fixture 23 and the fourth fixture 24 are respectively arranged at the two ends of the right half of the workbench 1, and the fifth fixture 25 is arranged at the center of the right half of the workbench 1, the left half of the workbench 1 is distributed with a plurality of first positioning columns 3, and the right half of the workbench 1 is distributed with a plurality of second positioning columns 4, the blank 7 includes a first part and a second part at different positions, the first fixture 21 and the second fixture 22 can respectively press down two first parts of the left blank 7 on the workbench 1 in a symmetrical relationship, the third fixture 23 and the fourth fixture 24 can respectively press down two second parts of the right blank 7 on the workbench 1 in a symmetrical relationship, and the fifth fixture 25 can press down the center of the right blank 7 on the workbench 1.

[0025] Chamfering steps:

[0026] 1. Place the blank on the left half of the workbench so that it is exactly located at the corresponding position of the first positioning column, so that the first positioning column pre-positions the blank;

[0027] 2. Press down two symmetrical first portions of the blank with a first clamp and a second clamp;

[0028] 3. Start the lathe and chamfer the position other than the first part of the blank. After completion, the lathe automatically shuts down and the first and second clamps release the pressure on the blank.

[0029] 4. Place the blank that has been chamfered at the first part in step 3 onto the right half of the workbench so that it is exactly located at the corresponding position of the second positioning post, so that the second positioning post can pre-position the blank;

[0030] 5. Use the third and fourth clamps to press down the two symmetrical second portions of the blank, and use the fifth clamp to press down the middle portion of the blank 7;

[0031] 6. Start the lathe and chamfer the second part and the position other than the middle part of the blank. After completion, the lathe automatically shuts down, and the third, fourth and fifth clamps release the pressure on the blank, completing the entire chamfering work of the blank.

[0032] The blank was clamped twice from the left half to the right half of the workbench and chamfered in stages because the clamped position could not be chamfered when it was clamped for the first time. Therefore, the blank was clamped in a different position during the second clamping, so that the position that was not processed in the first clamping could be chamfered.

[0033] In order to improve the efficiency of chamfering, all the first positioning columns form a first positioning profile 31 and a second positioning profile 32 which are symmetrically arranged in front and back on the left half of the workbench. The first positioning profile can position the blank I, and the second positioning profile can position the blank II. The first clamp 21 can press down the left ends of the blank I and the blank II, and the second clamp 22 can press down the right ends of the blank I and the blank II. In this way, during the process of S3, the lathe can chamfer the blank I and the blank II at the same time, and process two blanks 7 at the same time at one time;

[0034] Also, in order to improve the efficiency of chamfering, all the second positioning columns 4 form a third positioning contour 41 and a fourth positioning contour 42 that are symmetrical and arranged front to back on the right half of the workbench 1. The third positioning contour can position the blank III, and the fourth positioning contour can position the blank IV. The third clamp 23 can press down the left ends of the blank III and the blank IV, the fourth clamp 24 can press down the right ends of the blank III and the blank IV, and the fifth clamp 25 can press down the middle of the blank III and the blank IV at the same time; in this way, during the S5 process, the lathe can chamfer the blank III and the blank IV at the same time, and process two blanks 7 at the same time.

[0035] Specifically, each fixture includes a pressure plate 211 and a telescopic cylinder 212. The pressure plate 211 is located above the workbench 1. A first boss is provided at the bottom of the pressure plate 211. The telescopic cylinder 212 is fixed below the workbench 1. The boss passes through the workbench 1 and is fixed to the telescopic rod of the telescopic cylinder 212. When the telescopic rod of the telescopic cylinder 212 is shortened, the pressure plate 211 descends, pressing the blank 7. When the telescopic rod of the telescopic cylinder 212 is extended, the pressure plate 211 ascends, releasing the pressure on the blank 7.

[0036] In order to enable the telescopic cylinder 212 to be fixed on the present invention instead of being fixed on the ground, so as to facilitate the movement of the present invention, a plurality of pillars 5 are fixed to the bottom surface of the workbench 1, and the bottoms of the plurality of pillars 5 are fixed to a base plate 6. The telescopic cylinders 212 are all fixed to the top surface of the base plate 6, so that the entire processing tooling can be moved to meet the need of changing the position next time.

[0037] The first positioning column 3 includes first clamping columns 33 on the left and right sides and a first sleeve column 34 in the middle. The first clamping columns 33 can clamp the end of the blank 7 on the left side of the workbench 1 in pairs. A number of positioning holes 71 are provided in the center of the blank 7 on the left side of the workbench 1, and the positioning holes 71 can be sleeved outside the first sleeve column 34; the second positioning column 4 includes second clamping columns 43 on the left and right sides and a second sleeve column 44 in the middle. The second clamping columns 43 can clamp the end of the blank 7 on the right side of the workbench 1 in pairs. A number of positioning holes 71 are provided in the center of the blank 7 on the right side of the workbench 1, and the positioning holes 71 can be sleeved outside the second sleeve column 44.

[0038] Chamfering the blank 7 can remove edge burrs and make the edges more rounded, preventing the product from stabbing or cutting people.

[0039] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
