[0025] The clamp 3 includes: a guide rail 31, a first clamping arm 32, a second clamping arm 33 and a clamping drive mechanism 34. The guide rail 31 is fixed on the flip seat 2. The first clamping arm 32 and the second clamping arm 33 are installed on the guide rail 31.

[0026] The first clamping arm 32 includes: a first sliding seat 321, a first connecting arm 322 and a first positioning arm. The first sliding seat 321 is slidably connected to the slide rail. The first sliding seat 321 is connected to the first connecting arm 322. The first positioning arm is fixed to the first connecting arm 322. The first positioning arm is used to position the arc block 10, the first inclined block 11 and the second inclined block 12 on the first side wall of the workpiece to be processed.

[0027] The first positioning arm includes: a first side upper clamping block 323 and a first side lower clamping block 324, both of which are fixed on the first connecting arm 322, the first side upper clamping block 323 is used to clamp the T-shaped structure formed by connecting the arc block 10 and the first inclined block 11, and the first side lower clamping block 324 is used to clamp the second inclined block 12.

[0028] The first side upper clamping block 323 is provided with a first V-shaped groove and a first upper insertion groove, the first V-shaped groove is for the arc block 10 at the T-shaped structure to be inserted, and the first upper insertion groove is for the first inclined block 11 at the T-shaped structure to be inserted; the first side lower clamping block 324 is provided with a first lower insertion groove, and the first lower insertion groove is for the second inclined block 12 to be inserted.

[0029] The clamping drive mechanism 34 drives the first clamping arm 32 and the second clamping arm 33 in the X direction, the X direction is parallel to the first surface of the workpiece to be processed, the Y direction is parallel to the cylindrical hole in the workpiece to be processed, the Z direction is perpendicular to the X direction and the Y direction, and the X direction is perpendicular to the Z direction and the Y direction.

[0030] There is a distance between the first upper clamping block 323 and the first lower clamping block 324 in the Y direction, and there is a distance between the first upper clamping block 323 and the first lower clamping block 324 in the Z direction.

[0031] The second clamping arm 33 includes: a second sliding seat 331, a second connecting arm 332 and a second positioning arm. The second sliding seat 331 is slidably connected to the slide rail. The second sliding seat 331 is connected to the second connecting arm 332. The second connecting arm 332 is fixed with a second positioning arm. The second positioning arm is used to position the arc edge 13 and the strip edge 14 on the second side wall of the workpiece to be processed.

[0032] The first positioning arm includes: a second side upper clamping block 333 and a second side lower clamping block 334, both of which are fixed on the second connecting arm 332, the second side upper clamping block 333 is used to clamp the fork-shaped structure formed by connecting the arc-shaped edge 13 and the strip-shaped edge 14, and the second side lower clamping block 334 is used to clamp the strip-shaped edge 14.

[0033] First, the clamp 3 is designed to include: a guide rail 31, a first clamping arm 32, a second clamping arm 33 and a clamping drive mechanism 34, so that the entire clamp 3 presents a U-shaped structure, that is, the clamp 3 holds the first side wall and the second side wall of the workpiece to be processed, so that the first surface and the second surface of the workpiece to be processed can be exposed, so as to avoid the clamp 3 blocking the processing of the first surface and the second surface of the workpiece to be processed. Then, since the first surface and the second surface of the workpiece to be processed need to be exposed, the workpiece to be processed needs to be positioned in the X direction, the Y direction and the Z direction when the workpiece to be processed is flipped, so as to avoid the workpiece to be processed from being separated from the first positioning arm and the second positioning arm at will. Based on the above reasons, the first clamping arm 32 is designed to include the first positioning arm, and the second clamping arm 33 is designed to include the second positioning arm. The components on the first side wall and the second side wall of the workpiece to be processed of the present application cooperate with the first positioning arm and the second positioning arm, so as to achieve all-round positioning from the X direction, the Y direction and the Z direction. Specifically, The first positioning arm includes: a first side upper clamping block 323 and a first side lower clamping block 324. The first side upper clamping block 323 positions the arc block 10 and the first inclined block 11 to form a T-shaped structure, and the first side lower clamping block 324 positions the second inclined block 12. Since the arc block 10 is not parallel to any direction in the Y direction and the Z direction, after the arc block 10 is clamped, the workpiece to be processed will not move relative to the first positioning arm in a direction not parallel to the arc block 10. In order to maintain the stability of the first side upper clamping block 323 after being clamped, a first opening is provided on the first side upper clamping block 323. The first upper insertion groove is inserted into the first inclined block 11 at the T-shaped structure. The first inclined block 11 and the arc block 10 form a T-shaped structure, thereby limiting the movement of the first positioning arm along the arc block 10. Then, the first side lower clamping block 324 is used to clamp the second point on the first side wall of the workpiece to be processed. Since there is a downward pressure when processing the workpiece to be processed, and the workpiece to be processed is heavy, the two points on the first side wall are clamped and supported, so as to avoid the first inclined block 11 being clamped and supported only by the first side upper clamping block 323, resulting in the first inclined block 11 in the workpiece to be processed. 1 deformation damage, and also avoid the deformation of the first inclined block 11 during the machining process to affect the machining quality due to the change of the relative position of the machining. The first side lower clamping block 324 cooperates with the second inclined block 12 in the workpiece to be machined, and also has the function of supporting the entire workpiece to be machined, ensuring the supporting strength, and realizing double support for the first inclined block 11 and the second inclined block 12, avoiding the deformation of the first inclined block 11 and the second inclined block 12, and there is a spacing between the first side upper clamping block 323 and the first side lower clamping block 324 in the Z direction and the Y direction, thereby ensuring a wider clamping range and avoiding only one point of poor stability.In the second positioning arm, a second side upper clamping block 333 is set to hold the arcuate edge 13 and the strip edge 14 to form a fork-shaped structure, and the fork-shaped structure is a "cross" structure. The arcuate edge 13 is parallel to the first surface of the workpiece to be processed. The second side upper clamping block 333 clamps the arcuate edge 13 connected to the strip edge 14, that is, the strip edge 14 in the fork-shaped structure passes through the arcuate edge 13, so that the two sections of the arcuate edge 13 on both sides of the strip edge 14 are clamped, and the clamping range is wide, which avoids deformation of the arcuate edge 13 caused by only holding one section of the arcuate edge 13. The arcuate edge 13 mainly limits the movement of the workpiece to be processed in the Y direction, and simultaneously positions the strip edge 14 in order to avoid The workpiece to be processed moves in the Z direction. At the same time, since there are at least two strip edges 14 and arc edges 13, a number of square slots are formed. The second side upper clamping block 333 extends into the four square slots, so that the second side upper clamping block 333 can support the four arc edges 13 from the Y direction, avoiding deformation and damage of the arc edge 13 caused by supporting only a small arc edge 13. Since the second side upper clamping block 333 can already support the four arc edges 13 from the Y direction, the second side lower clamping block 334 does not need to support the arc edge 13 from the Y direction. The second side lower clamping block 334 is used to position the strip edge 14 to ensure the positioning support strength in the Z direction. Finally, the first positioning arm and the second positioning arm move closer to the middle, so that the workpiece to be processed is positioned in the X direction.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the present invention, which should be included in the scope of the claims of the present invention.
