[0041] A plurality of adjustable pressing pieces 20, which are arranged in the first grooves 11 one by one and connected with the base 10;

[0042] A stop piece 30 connected with the base 10 and arranged at the second groove 12, which, together with the adjustable pressing pieces 20, presses the semicircular arc part 100 at the first grooves 11, and the stop piece 30 has a plurality of third grooves 31, two of which form a group, the groups are arranged at intervals, each group of the third grooves 31 is aligned with one semicircular arc part 100, and one third groove 31 corresponds to one machined hole 101 on the semicircular arc part 100;

[0043] Specifically, in implementation, the base 10 forms a reliable support structure, which is conducive to connecting the adjustable pressing pieces 20 and the stop piece 30, the adjustable pressing pieces 20 are arranged at the first grooves 11, the stop piece 30 is arranged at the second groove 12, the semicircular arc part 100 is pressed between the adjustable pressing pieces 20 and the stop piece 30, and the third grooves 31 are used to drill and tap the machined holes 101 on the semicircular arc part 100, so that the clamping operation is relatively convenient, the clamping precision is relatively unified, the machining precision is ensured, and the semicircular arc part 100 is not damaged;

[0044] Another embodiment:

[0045] As shown in the figure; a clamp for quickly positioning and clamping a semicircular arc part, comprising:

[0046] Figure 1 , Figure 2 ​As shown; in practice, the base 10 is a rectangular plate structure with a regular shape, which is conducive to processing and manufacturing, and is also relatively aesthetically pleasing;

[0047] The base 10 has four first stepped through holes 13, which are spaced apart from the first groove 11 and the second groove 12. The first stepped through holes 13 facilitate the insertion of bolts to connect the base 10, for example, connecting the base 10 to a drilling machine, which makes assembly relatively convenient.

[0048] The first groove 11 includes: a first region 11-1 for setting the adjustable pressure member 20; and a second region 11-2, one end of which communicates with the first region 11-1 and the other end extends toward and communicates with the second groove 12. The second region 11-2 is used to set the semi-circular arc-shaped part 100. The presence of the first region 11-1 and the second region 11-2 facilitates the setting of the adjustable pressure member 20 and the semi-circular arc-shaped part 100, and facilitates the clamping of the semi-circular arc-shaped part 100 between the adjustable pressure member 20 and the stop member 30. The clamping operation is relatively convenient, the clamping accuracy is relatively uniform, and the semi-circular arc-shaped part 100 will not be damaged.

[0049] The length dimension A of the second groove 12 is greater than the width dimension B of the first groove 11; the width dimension B is the width between the starting edge of the first first groove 11 and the ending edge of the last first groove 11. For example, if there are five first grooves 11, the width dimension B is the width between the starting edge of the first first groove 11 and the ending edge of the fifth first groove 11. The control of the size is beneficial for the stop 30 to block the semi-circular arc part 100, and the semi-circular arc part 100 is pressed between the adjustable pressure member 20 and the stop 30.

[0050] Another implementation method:

[0051] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown; during implementation, the number of adjustable pressure pieces 20 is five, which matches the number of the first groove 11. In one clamping, five semi-circular arc-shaped parts 100 can be clamped. The clamping operation is relatively convenient, the clamping accuracy is relatively uniform, and the processing efficiency is improved.

[0052] The adjustable pressure member 20 includes: a threaded sleeve 21 connected to the base 10 and disposed in the first groove 11; two support blocks 22 symmetrically disposed in the first groove 11; a slider 23 disposed between the support blocks 22 and slidably connected to the support blocks 22; and a first bolt 24 passing through the slider 23, movably connected to the slider 23, and threadedly connected to the threaded sleeve 21.

[0053] The threaded sleeve 21 is a common structure in the prior art. It is connected to the base 10 and threadedly connected to the first bolt 24. When the threaded sleeve 21 is damaged, only the threaded sleeve 21 needs to be replaced, which protects the base 10 and reduces the cost of use.

[0054] The support block 22 has a right-angled trapezoidal structure and a groove 22-1 on one side wall; the groove 22-1 is a "T" shaped through groove, which facilitates the sliding position of the slider 23.

[0055] The slider 23 includes: a middle block 23-1, which has a second stepped through hole 23-11 through which the first bolt 24 passes; and two side blocks 23-2, which are symmetrically connected to the middle block 23-1 and slidably connected to the groove 22-1; the middle block 23-1 is roughly an isosceles trapezoidal structure, and the side blocks 23-2 are roughly T-shaped; the middle block 23-1 and the side blocks 23-2 are integrally formed.

[0056] The first bolt 24 is an internal hex bolt, which passes through the second stepped through hole 23-11 and is threadedly connected to the threaded sleeve 21.

[0057] In use, by rotating the first bolt 24, the slider 23 is moved along the slide groove 22-1 on the support block 22, thereby moving the support block 22 along the first groove 11. The support block 22 pushes the semi-circular part 100 to move towards the baffle 32 until the semi-circular part 100 is pressed between the support block 22 and the baffle 32, making the clamping operation relatively convenient.

[0058] Another implementation method:

[0059] like Figure 1 , Figure 2 As shown; in implementation, the stop 30 includes: a baffle 32 disposed at the second groove 12, the baffle 32 having the third groove 31; at least two positioning pins 33 connecting the baffle 32 and the base 10; and a plurality of second bolts 34 connecting the baffle 32 and the base 10;

[0060] The third groove 31 is a U-shaped through groove, and there are ten of them. It is beneficial to guide the drill bit and tap to process the hole 101.

[0061] The baffle 32 is a rectangular plate structure with a regular shape, which is conducive to processing and manufacturing, and is also relatively aesthetically pleasing.

[0062] There are two locating pins 33, such as cylindrical pins, used for positioning and connecting the baffle 32 and the base 10, which improves the positioning accuracy and facilitates the alignment of the third groove 31 with the machined hole 101.

[0063] The second bolt 34 is an internal hex bolt, used to connect the locking baffle 32 and the base 10, which is relatively easy to install and remove.

[0064] After the baffle 32 is connected to the second groove 12, one side surface C of the baffle 32 is flush with one end face D of the base 10. The surface C is the upper surface of the baffle 32, and the end face D is the upper end face of the base 10, which is relatively aesthetically pleasing.

[0065] Another implementation method:

[0066] like Figure 1 , Figure 2 As shown; in practice, it also includes: a number of process holes 40, which are respectively set at the corners of the first groove 11 and the second groove 12; the process holes 40 are round holes, which play a role in avoiding obstruction, preventing the adjustable pressure piece 20 from being blocked by the corner when it is inserted into the first groove 11, resulting in improper fit, and also preventing the baffle 32 from being blocked by the corner when it is inserted into the second groove 12, resulting in improper fit, and the clamping operation is relatively convenient;

[0067] Regarding the semi-circular arc-shaped part 100:

[0068] See Figure 1 The semi-circular arc-shaped part 100 has a semi-circular arc-shaped structure. After being pressed by the adjustable pressure member 20 and the stop member 30, it drills and taps the machined hole 101. Those skilled in the art can directly and without doubt know how to set it up after seeing the disclosed content. They do not need to put in creative effort or conduct excessive experiments.

[0069] The working principle is as follows: The adjustable pressure member 20 is set at the first groove 11, and the stop member 30 is set at the second groove 12. The semi-circular arc part 100 is pressed between the adjustable pressure member 20 and the stop member 30. Then, the machined hole 101 on the semi-circular arc part 100 is drilled and tapped from the third groove 31. This makes the clamping operation relatively convenient, the clamping accuracy relatively uniform, and ensures the machining accuracy without damaging the semi-circular arc part 100.
