[0001] This patent relates to the field of mechanical processing technology, specifically a five-axis machining center that is easy to clamp. Background Art

[0002] The five-axis machining center is a high-tech, high-precision machining center specially used for machining complex curved surfaces. During machining, the workpiece needs to be clamped on a rotatable chuck;

[0003] A five-axis machining center with convenient clamping is proposed in the publication number CN220145296U. In order to facilitate clamping, a gear ring is arranged on the outer side of the threaded sleeve so that it can synchronously drive multiple threaded sleeves to rotate, thereby achieving the purpose of convenient clamping;

[0004] However, in the above document, the gear ring is located on the outside of the workpiece, which will block the workpiece and make it impossible to process the outer side of the workpiece. Utility Model Content

[0007] The auxiliary clamping mechanism includes a base, a fixed column, a sliding groove and a top holding plate. The base is clamped and installed on the chuck. The upper wall of the base is installed with a fixed column. The left and right sides of the fixed column are provided with sliding grooves. Top holding plates are slidably installed in the two sliding grooves. The side walls of the top holding plates are inclined. The annular workpiece is sleeved on the outer side of the fixed column, and the side walls of the top holding plate are in contact with the inner ring of the annular workpiece.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of this patent to clearly and completely describe the technical solutions in the embodiments of this patent. Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0020] See also Figure 1-3This patent provides a technical solution: a five-axis machining center that is convenient for clamping, including a five-axis machining center machine tool 1 and a chuck 2, the chuck 2 is installed on the rotatable turntable in the middle of the five-axis machining center machine tool 1, the upper wall of the chuck 2 is clamped and installed with an auxiliary clamping mechanism 3, and the outside of the auxiliary clamping mechanism 3 is clamped with a ring-shaped workpiece 4;

[0021] According to the size of the annular workpiece 4, it is determined whether the annular workpiece 4 is fixed directly by the chuck 2 or by the auxiliary clamping mechanism 3.

[0022] When a larger annular workpiece 4 is fixed by the chuck 2, the claws on the upper side of the chuck 2 can be clamped on the inner ring of the annular workpiece 4, thereby fixing the annular workpiece 4;

[0023] When a smaller annular workpiece 4 is fixed by the auxiliary clamping mechanism 3, the annular workpiece 4 is sleeved on the fixing column 32, and then the two holding plates 34 are pushed upward by rotating the nut 8 to be inserted into the inner ring of the annular workpiece 4, and then the annular workpiece 4 is fixed by the pressing plate 7 on the bolt 6;

[0024] The auxiliary clamping mechanism 3 includes a base 31, a fixed column 32, a slide groove 33 and a top holding plate 34. The base 31 is clamped and installed on the chuck 2. The upper wall of the base 31 is installed with a fixed column 32. The left and right sides of the fixed column 32 are provided with a slide groove 33. The top holding plates 34 are slidably installed in the two slide grooves 33. The side walls of the top holding plates 34 are inclined. The annular workpiece 4 is sleeved on the outer side of the fixed column 32, and the side walls of the top holding plates 34 are in contact with the inner ring of the annular workpiece 4.

[0025] Since the side wall of the top holding plate 34 in the device is an inclined surface, it can be suitable for annular workpieces 4 of different sizes.

[0026] Specifically, a threaded hole 5 is opened on the upper wall of the fixing column 32 , a bolt 6 is rotatably installed in the threaded hole 5 , a pressure plate 7 is sleeved on the outside of the bolt head above the bolt 6 , and the lower wall of the pressure plate 7 is in contact with the upper wall of the annular workpiece 4 .

[0027] Specifically, an external thread is provided on the outer side of the fixing column 32 , and a nut 8 is rotatably installed on the outer side of the fixing column 32 through the external thread. A top ring 9 is installed on the upper wall of the nut 8 , and the upper wall of the top ring 9 is in contact with the lower wall of the top holding plate 34 .

[0028] Specifically, a rubber pad 10 is fitted on the upper wall of the fixed column 32. There are two rubber pads 10. The two rubber pads 10 are respectively arranged on both sides of the fixed column 32. The two rubber pads 10 can cover the slide groove 33. The rubber pad 10 can be arranged between the annular workpiece 4 and the top holding plate 34.

[0029] On the one hand, the rubber pad 10 can shield the slide groove 33 to prevent iron filings in the corners from entering the slide groove 33 during processing and affecting the sliding of the top holding plate 34. On the other hand, it can also prevent the top holding plate 34 from scratching the inner wall of the annular workpiece 4.

[0030] Specifically, the upper wall of the pressing plate 7 is provided with a groove 11, and the groove 11 is in a cross shape;

[0031] By inserting an external cross screwdriver into the screw groove 11 , it is convenient for a worker to rotate the bolt 6 .

[0032] Specifically, a rubber ring 12 is fitted on the lower wall of the pressing plate 7, and the rubber ring 12 fits on the upper wall of the annular workpiece 4;

[0033] The rubber ring 12 can protect the annular workpiece 4 and prevent the pressing plate 7 from scratching the upper wall of the annular workpiece 4 .

[0034] Working principle: When machining a larger annular workpiece 4, the annular workpiece 4 is clamped directly by the chuck 2, and then the machining program is input and started on the control panel of the five-axis machining center 1, and the annular workpiece 4 is cut by the milling cutter on the five-axis machining center 1;

[0035] If the annular workpiece 4 is small, directly clamping it with the chuck 2 will affect the cutting. In this case, the annular workpiece 4 needs to be fixed with the auxiliary clamping mechanism 3.

[0036] First, the annular workpiece 4 is sleeved on the fixing column 32 , and then the nut 8 is rotated to push the two supporting plates 34 upward so that they are inserted into the inner ring of the annular workpiece 4 , and then the annular workpiece 4 is fixed by the pressing plate 7 on the bolt 6 .

[0037] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be considered exemplary and non-restrictive in all respects, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
