[0034] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention clearer and more understandable, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0035] Example 1

[0036] See also Figures 1 to 3 , is a rotary clamp for auxiliary processing as embodiment 1 of the utility model, which can be used in conjunction with an ordinary three-axis milling machine and is used to process the outer surface of the workpiece 01 to be processed, including a base 10, a clamping mechanism 20, a positioning member 30, and a locking member 40. At least two first positioning holes 11 are arranged on the base 10; the clamping mechanism 20 is used to install the workpiece 01 to be processed and is arranged on the base 10, and a plurality of second positioning holes 211 are arranged on the clamping mechanism 20; at least two positioning members 30 are arranged and are arranged corresponding to the first positioning holes 11, and the positioning member 30 passes through the first positioning hole 11 and is embedded in the second positioning hole 211; at least one locking member 40 is arranged and is used to lock the clamping mechanism 20 on the base 10. The locking member 40 of this embodiment can be directly bolted, and quick-release bolts can be used to improve the efficiency of locking and loosening. The utility model rotary clamp is provided with a clamping mechanism 20 on a base 10 for clamping a workpiece 01 to be processed, and a first positioning hole 11 and a second positioning hole 211 are provided for positioning. The clamping mechanism 20 is rotated, and a plurality of second positioning holes 211 correspond to the first positioning hole 11 in sequence to realize processing at different positions.

[0037] The workpiece 01 involved in the utility model is cylindrical as a whole and hollow inside, and a plurality of processing positions 02 need to be processed on the outer surface. The processing position 02 is any one of a through hole, a groove or a stepped hole. The processing positions 02 are arranged in sequence along the central axis direction of the workpiece 01 to be processed and cover the outer surface of the workpiece 01 to be processed. During processing, a row of processing positions 02 are first processed along the central axis direction of the workpiece 01 to be processed, and then the clamping mechanism 20 is rotated to process a plurality of rows of processing positions 02 in sequence. The number of second positioning holes 211 is set according to the number of rows of the processing positions 02. Specifically, the plurality of second positioning holes 211 are arranged in a circular array on the surface of one end of the clamping mechanism 20; the positioning member 30 passes through the first positioning hole 11 and is embedded in the second positioning hole 211.

[0038] The clamping mechanism 20 includes a fixed disk 21, a fixed plate 22 and a first bolt 23. When the workpiece 01 is clamped, the workpiece 01 is arranged between the fixed disk 21 and the fixed plate 22, and the first bolt 23 is screwed to the fixed disk 21 after fixing the plate 22 and the fixed plate 22 in sequence; a plurality of second positioning holes 211 are arranged on the fixed disk 21.

[0039] A positioning step 212 for positioning the workpiece 01 to be processed is provided on the end surface of the fixed disk 21, and the inner side wall of the workpiece 01 to be processed is sleeved on the positioning step 212, which plays a role in positioning the workpiece 01 to be processed. The locking member 40 passes through the base 10 and is screwed to the fixed disk 21. The fixed plate 22 is provided with a first hole position 221 for the threaded end of the first bolt 23 to pass through and can prevent the head of the first bolt 23 from passing through. When the clamping mechanism 20 is clamped, the fixed plate 22 and the first bolt 23 are first removed, the workpiece 01 to be processed is placed on the fixing plate, and sleeved on the positioning step 212, and then the fixed plate 22 is pressed against the end face of the workpiece 01 to be processed, the end of the first bolt 23 passes through the fixed plate 22 in turn and is screwed to the workpiece 01 to be processed and the fixed disk 21, and the first bolt 23 is rotated and locked so that the workpiece 01 to be processed is fixed or restricted between the fixed disk 21 and the fixed plate 22, and an internal threaded hole is provided on the fixed disk 21 for connecting with the first bolt 23.

[0040] The base 10 of the present invention is L-shaped as a whole, including a vertical portion and a horizontal portion, and the angle between the vertical portion and the horizontal portion is determined according to the processing position 02 of the workpiece 01 to be processed.

[0041] After the installation of the clamping mechanism 20 of the utility model is completed, the clamping mechanism 20 with the workpiece 01 to be processed is positioned on the base 10 through the positioning member 30, and is locked on the base 10 by the locking member 40. When the processing of the processing position 02 located in the same row is completed, the locking member 40 is released, and the positioning member 30 is pushed out of the second positioning hole 211, and the positioning member 30 is rotated and moved. After the next second positioning hole 211 is aligned with the first positioning hole 11, the positioning member 30 is inserted, and then the locking member 40 is locked to process the next row of processing positions 02. The operations are performed in sequence so that the processing can cover the entire outer surface of the workpiece 01 to be processed, so that the processing of the workpiece 01 to be processed can be completed using an ordinary three-axis milling machine.

[0042] Example 2

[0043] See also Figures 4 to 7, is a rotating clamp for auxiliary processing as embodiment 2 of the utility model. The difference between this embodiment and embodiment 1 is that the clamping mechanism 20 also includes a limit plate 24. Specifically, a first hole position 221 for the threaded end of the first bolt 23 to pass through is set on the fixing plate 22, and the inner diameter of the first hole position 221 is larger than the outer diameter or the circumscribed circle diameter of the head of the first bolt 23. The clamping mechanism 20 also includes a limit plate 24 for preventing the fixing plate 22 from passing through the head of the first bolt 23. After the workpiece 01 is clamped, the limit plate 24 is located between the head of the first bolt 23 and the fixing plate 22; a second hole position 241 is set inside the limit plate 24, and the outer wall is set at a clamping channel 242 connected to the second hole position 241. When clamping using the clamping mechanism 20 of Example 2, first screw the first bolt 23 onto the fixed plate 21 and reserve enough assembly space. Then, the workpiece 01 to be processed and the fixed plate 22 are passed through the head of the first bolt 23 in turn. Then, the limiting plate 24 is inserted from the side wall of the first bolt 23. Finally, the first bolt 23 is tightened. After the workpiece 01 to be processed is processed, it is only necessary to loosen the first bolt 23 and remove the limiting plate 24. The fixed plate 22 and the processed workpiece 01 can be removed in turn without completely unscrewing the first bolt 23. This can improve the efficiency of assembly and disassembly.

[0044] The end surface of the fixing plate 22 is also provided with a limiting groove 222 for embedding the limiting plate 24. When the limiting plate 24 is placed on the first bolt 23, the limiting plate 24 is directly embedded in the limiting groove 222, and the first bolt 23 can be rotated without manual support, thereby further improving the assembly efficiency. At the same time, a magnet can be embedded at the bottom of the limiting plate 24 to absorb the metal fixing plate 22, so that the limiting plate 24 is better confined in the limiting groove 222 of the fixing plate 22.

[0045] Example 3

[0046] See also Figures 5 to 6 , is a rotary clamp for auxiliary processing as embodiment 3 of the utility model. The difference between this embodiment and embodiment 1 or 2 is that a rotating step 213 is added to the fixing plate to facilitate the rotation and transposition of the clamping mechanism 20. Specifically, a rotating step 213 is also provided on the fixing plate 21, and a rotating hole 12 for cooperating with the rotating step 213 is provided on the base 10. When the rotating step 213 is not only used for the rotation of the clamping mechanism 20 but also for positioning, only one first positioning hole 11 and one positioning member 30 are provided at this time, and multiple positioning members 30 can also be provided at that time. After a row of processing positions 02 is processed, when rotation switching is required, the locking member 40 is released, and the positioning member 30 is withdrawn from the second positioning hole 211. After the next second positioning hole 211 is manually rotated to the first positioning hole 11, the positioning member 30 is inserted, and finally the locking member 40 is locked, which further improves the efficiency of rotation switching.

[0047] In order to better make the clamping structure rest against the base 10, the end of the rotating step 213 passes through the base 10 and is screwed with a nut 50. A spring 60 is also arranged between the nut 50 and the step. The spring 60 is sleeved on the rotating step 213 to make the clamping mechanism 20 rest against the base 10.

[0048] In summary, the utility model rotary clamp is provided with a clamping mechanism on the base for clamping the workpiece to be processed, and a first positioning hole and a second positioning hole are provided for positioning, and the clamping mechanism is rotated, and a plurality of second positioning holes correspond to the first positioning holes in sequence to realize processing at different positions.

[0049] The utility model is described above by way of example in conjunction with the accompanying drawings. It is obvious that the specific implementation of the utility model is not limited to the above-mentioned method. As long as various non-substantial improvements are made using the method concept and technical solution of the utility model, or the concept and technical solution of the utility model are directly applied to other occasions without improvement, they are all within the protection scope of the utility model.
