[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] according to Figures 1 to 3As shown, the utility model is a small machine tool for flange processing, including a fixing mechanism 1 and a grinding mechanism 2 arranged on one side of the fixing mechanism 1. The fixing mechanism 1 includes a fixing plate 3, a first clamping base 4 and a second clamping base 5 are provided on the fixing plate 3, a processing groove 30 is provided between the first clamping base 4 and the second clamping base 5, and a flange support column 8 is provided on the processing groove 30. The flange for processing is fixed on the flange support column 8, and the first clamping base 4 is provided with a first clamping disk 6, and the second clamping base 5 is provided with a second clamping disk 7. The flange support column 8 is clamped between the two, and the flange is fixed on the flange support column 8 to ensure its stability during the processing. In order to further improve the fixing effect, the second clamping base 5 is provided with a protrusion 9, and the protrusion 9 is hinged with a swing arm 10, which can rotate flexibly. The third clamping disk 11 is installed on the swing arm 10. The third clamping disk 11 is adjusted by the swing arm 10 and abuts against the front end of the flange support column 8, thereby stabilizing the support column and preventing it from displacement during processing. The grinding mechanism 2 includes a grinding disc 12, the position of which corresponds to the flange support column 8, and is used to precisely grind the surface of the flange to ensure processing accuracy. The first clamping disc 6 and the second clamping disc 7 are respectively provided with a first offset groove 13 and a second offset groove 14. The third clamping disc 11 can pass through these two offset grooves and tightly abut against the flange support column 8 without colliding with the first clamping disc 6 and the second clamping disc.

[0028] according to Figure 4 As shown, a limit plate 15 is provided between the first clamping base 4 and the second clamping base 5 to limit the range of movement of the flange support column 8. The limit plate 15 is tightly abutted against the rear end of the flange support column 8 to avoid displacement or loosening during processing. A limit column 16 is provided on the limit plate 15, which is located between the fixed plate 3 and the fixed block 17. With the support of the limit column 16, the limit plate 15 is more stable and reliable, effectively improving the processing accuracy. The second clamping base 5 is provided with a handle 18 for driving the swing arm 10 to rotate. The handle 18 is connected to a gear 19, which meshes with a rack 20. The rack 20 is also provided with a push rod 21. The push rod 21 is directly abutted against the swing arm 10 to promote the rotation of the swing arm 10. Through the rotation of the handle 18, the gear 19 drives the rack 20 to move, and the movement of the rack 20 further pushes the push rod 21, thereby causing the swing arm 10 to rotate around the hinge point.

[0029] A driving motor 22 is provided at the rear end of the second clamping base 5 , and the driving motor 22 drives the second clamping plate 7 to rotate inward, so that the first clamping plate 6 and the second clamping plate 7 clamp the flange support rod.

[0030] according to Figure 5As shown, the grinding mechanism 2 includes a grinding base 23, on which is a movable plate 24, and a grinding bracket 25 is mounted. The grinding bracket 25 is the main structure for mounting the grinding disc 12. The grinding disc 12 is fixed to the grinding bracket 25 and is used to precisely grind the flange on the flange support column 8. Slide rails 26 parallel to the flange support column 8 are provided on both sides of the grinding base 23, allowing the grinding mechanism 2 to move axially along the flange support column 8. A first slider 27 is slidably mounted on the slide rail 26. The first slider 27 is fixed to the grinding base 23, ensuring smooth movement of the grinding base 23 on the slide rail 26. At the same time, the movable plate 24 is also provided with a slide groove 28 perpendicular to the slide rail 26. A second slider 29 is slidably mounted in the slide groove 28. The second slider 29 is fixed to the bottom of the grinding bracket 25. The movement of the second slider 29 in the slide groove 28 can achieve left and right adjustment of the grinding bracket 25, conveniently adjusting the position and angle of the grinding disc 12.

[0031] When the present invention is used, first, the flange to be processed is fixed on the flange support column 8, and the flange support column 8 is placed between the first clamping plate 6 and the second clamping plate 7 of the machine tool. The operator can drive the rotation of the swing arm 10 through the handle 18, so that the third clamping plate 11 abuts against the front end of the flange support column 8, and the gear 19 on the handle 18 engages with the rack 20, and the swing arm 10 is further pushed by the push rod 21, thereby completing the clamping of the flange support column 8. In order to ensure the stability of the rear end of the support column, the limit plate 15 is abutted against the flange support column 8, and cooperated with the fixed plate 3 and the fixed block 17 through the limit column 16 to further enhance the support and fixing effect. Next, we are ready to start grinding. The movable plate 24 can move back and forth through the slide rail 26 and the slider. According to the grinding requirements, the position of the movable plate 24 can be adjusted by the cylinder so that the grinding disc 12 is accurately aligned with the area of ​​the flange that needs to be ground. At the same time, the grinding bracket 25 slides in the slide groove 28 perpendicular to the slide rail 26 through the second slider 29 at its bottom, so that the grinding disc 12 can move left and right to adapt to the position of the flange support column 8 and achieve precise surface grinding.

[0032] The beneficial effects brought by the utility model are:

[0033] The utility model clamps and fixes the flange support column at multiple points through multiple clamping plates, thereby ensuring that the flange remains stable during the processing and improving the processing accuracy.

[0034] The utility model can be used for processing flanges of different sizes, is adapted to processing tasks of various types of flanges, and meets a variety of industrial processing needs.

[0035] The operator can adjust the position of the swing arm through simple manual operation, easily clamping and releasing the flange support column, and improving work efficiency.

[0036] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
