[0002] During workpiece machining, it is generally necessary to first position the workpiece using a positioning device. Existing positioning devices typically include two clamping blocks, with the distance between the two blocks adjusted by a screw to clamp the workpiece, facilitating the machining of designated areas on the workpiece.

[0003] However, when a workpiece has multiple parts with different angles that need to be machined, after machining one part of the workpiece, the workpiece needs to be removed from the positioning device, and after adjusting the workpiece angle, it needs to be reinstalled on the positioning device in order to machine the other parts.

[0004] Therefore, the workpiece needs to be installed and removed from the positioning device multiple times, making it difficult to guarantee the positional accuracy of the workpiece after each clamping, and the efficiency is low. Utility Model Content

[0090] The accompanying drawings, which are incorporated in and form part of this specification, illustrate embodiments consistent with this application and, together with the description, serve to explain the principles of this application. Detailed Implementation

[0091] To better understand the technical solution of this application, the embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0092] It should be understood that the described embodiments are merely some, not all, of the embodiments in this application. All other embodiments obtained by those skilled in the art based on the embodiments in this application without inventive effort are within the scope of protection of this application.

[0093] The terminology used in the embodiments of this application is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The singular forms “a,” “the,” and “the” used in the embodiments of this application and the appended claims are also intended to include the plural forms unless the context clearly indicates otherwise.

[0094] It should be understood that the term "and / or" used in this article is merely a description of the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, and B existing alone. Additionally, the character " / " in this article generally indicates that the preceding and following related objects have an "or" relationship.

[0095] It should be noted that the directional terms such as "upper," "lower," "left," and "right" described in the embodiments of this application are used to describe the angles shown in the accompanying drawings and should not be construed as limiting the embodiments of this application. Furthermore, in the context, it should be understood that when it is mentioned that an element is connected "upper" or "lower" to another element, it can be directly connected to the other element "upper" or "lower," or indirectly connected to the other element "upper" or "lower" through an intermediate element.

[0096] During the machining process, the workpiece generally needs to be fixed onto a positioning device such as a fixture or tooling to ensure its stability. Existing positioning devices typically include two clamping blocks, with the distance between the two blocks adjusted by a screw to clamp the workpiece, facilitating the machining of designated areas on the workpiece, such as machining designated surfaces.

[0097] However, when a workpiece has multiple parts with different angles that need to be machined, after machining one part, the workpiece needs to be removed from the positioning device, its angle adjusted, and then reinstalled on the positioning device to machine the other parts. This requires repeatedly installing and removing the workpiece from the positioning device, making it difficult to guarantee the positional accuracy of the workpiece after each clamping, and is also inefficient.

[0098] Furthermore, the existing positioning device that uses two clamping blocks to fix the workpiece is suitable for two opposite sides of the workpiece that are parallel to each other. However, for two opposite sides of the workpiece that are not parallel, it is not possible to stably clamp them with two clamping blocks. It is necessary to manufacture additional contour clamping blocks, which increases costs. Replacing the clamping blocks also reduces processing efficiency.

[0099] Figure 1 This is a schematic diagram of the structure of a positioning device provided in one embodiment of this application, as shown below. Figure 1 As shown in the figure, this application embodiment provides a positioning device, which includes a body 1, a rotating member 2, a platform assembly 3, and a clamping assembly 4. The rotating member 2 is rotatably connected to the body 1, and has a first rotating shaft C1 around which it rotates. The platform assembly 3 is rotatably connected to the rotating member 2, and has a second rotating shaft C2 around which it rotates. The extending direction of the first rotating shaft C1 intersects the extending direction of the second rotating shaft C2. The clamping assembly 4 is movably connected to the platform assembly 3 for clamping a workpiece (not shown in the figure).

[0100] The main body 1 is the supporting structure of the positioning device. For example, the main body 1 may include a base plate 11, and the rotating part 2, the platform assembly 3 and the clamping assembly 4 can all be set above the base plate 11. The base plate 11 can be installed on the corresponding fixture to facilitate the overall movement and installation of the positioning device.

[0101] The rotating component 2 can rotate around the first axis C1 within a certain angle range. For example, the rotating component 2 can rotate within a 90° range or a 180° range around the first axis C1, and of course, it can also rotate within other angle ranges. Since the clamping assembly 4 is connected to the rotating component 2, the rotating component 2 can drive the clamping assembly 4 to move around the first axis C1.

[0102] The clamping assembly 4 can rotate relative to the rotating member 2 around the second rotating axis C2, and can rotate within a 360° range around the second rotating axis C2. Exemplarily, the extending direction of the first rotating axis C1 is perpendicular to the extending direction of the second rotating axis C2. In this embodiment, the clamping assembly 4 can both rotate with the rotating member 2 around the first rotating axis C1 and rotate relative to the rotating member 2 around the second rotating axis C2. Therefore, through the cooperation of the rotating member 2 and the clamping assembly 4, the processing angle of the workpiece can be adjusted, enabling processing at multiple different angles on the workpiece without disassembling it, and ensuring the consistency of the workpiece's positional accuracy on the positioning device.

[0103] For example, in this embodiment, when the workpiece to be processed is a cuboid, the five sides of the workpiece can be processed by rotating and adjusting the rotating component 2 and the clamping component 4, thereby effectively improving processing efficiency and processing accuracy.

[0104] Figure 2 This is a state diagram of the positioning device provided in one embodiment of this application when machining the top surface of a workpiece, as shown below. Figure 2 As shown, when the workpiece is clamped on the clamping assembly 4, the top surface of the workpiece faces upward, thus allowing the top surface of the workpiece to be machined. Here, "upper" refers to the side perpendicular to the base plate 11 and located on the side of the base plate 11 facing the stage assembly 3.

[0105] Figure 3 This is a state diagram of the positioning device provided in one embodiment of this application when processing the side of a workpiece. The positioning device is composed of... Figure 2 The status shown has been switched to Figure 3 In the indicated state, the rotating component 2 has rotated a certain angle relative to the body 1, for example, 90°. In this state, the side of the workpiece faces upward, thus allowing the side of the workpiece to be machined.

[0106] Figure 4 This is a state diagram of the positioning device provided in another embodiment of this application when machining the side of a workpiece. Figure 3 In the state shown, the platform assembly 3 can be switched to a position after rotating 90° relative to the rotating member 2 around the second axis C2. Figure 4 The state shown allows the other side of the workpiece to face upwards, thus enabling the processing of different sides of the workpiece without disassembling it.

[0107] Figure 5 This is an exploded view of the interaction between the rotating member 2 and the base 12 in a positioning device provided in one embodiment of this application. Figure 5 As shown, the rotating component 2 can be rotatably connected to the body 1 via the rotating shaft 5. Specifically, the rotating component 2 can be rotatably connected to the base 12 in the body 1 via the rotating shaft 5, thereby ensuring the stable rotation of the rotating component 2 relative to the body 1.

[0108] like Figure 5 As shown, the body 1 includes a first limiting surface 121 and a second limiting surface 122, which are distributed around a first rotation axis C1 and intersect. The rotating member 2 can rotate between the first limiting surface 121 and the second limiting surface 122. The body 1 includes a base 12, and the rotating member 2 is rotatably connected to the base 12. The first limiting surface 121 and the second limiting surface 122 are formed on the base 12, and the included angle between the first limiting surface 121 and the second limiting surface 122 can be 90° or greater than 90°. The rotating member 2 can achieve rotational limitation by contacting the first limiting surface 121 or the second limiting surface 122.

[0109] Figure 6 This is an exploded view of the engagement between the platform assembly 3 and the rotating member 2 in a positioning device according to an embodiment of this application. Figure 6 As shown, the platform assembly 3 includes a first support 31 and a second support 32, which are fixedly connected, for example, by screws. The first support 31 is rotatably connected to the end of the rotating member 2 away from the rotating shaft 5 around the second rotating shaft C2, and the clamping assembly 4 is movably connected to the second support 32. The first support 31 and the second support 32 are independent structures and can be assembled separately. For example, during the assembly of the positioning device, the first support 31 can be assembled independently with the rotating member 2, thereby ensuring the assembly accuracy of the first support 31 and the rotating member 2 and facilitating assembly operations. The clamping assembly 4 and the second support 32 can be assembled independently, and then the assembled clamping assembly 4 and the second support 32 can be integrally assembled onto the first support 31, thus facilitating assembly operations.

[0110] like Figure 6 As shown, the rotating member 2 may be provided with a shaft portion 21, and the first support 31 is provided with a first through hole 311. The first support 31 is rotatably sleeved on the shaft portion 21 through the first through hole 311, thereby ensuring that the first support 31 can rotate smoothly relative to the rotating member 2, while preventing the first support 31 from being displaced relative to the rotating member 2.

[0111] like Figure 6As shown, the rotating component 2 is also provided with a limiting part 22. The shaft part 21 is located on the side of the limiting part 22 away from the main body 1. The diameter of the limiting part 22 is larger than the diameter of the shaft part 21 and the diameter of the first through hole 311. The limiting part 22 is used to limit the first support 31. After the first support 31 is installed on the rotating component 2, the part of the first support 31 located around the first through hole 311 can contact the limiting part 22 to achieve limitation, preventing the first support 31 from moving axially relative to the rotating component 2 in the axial direction of the first through hole 311, and ensuring stability during the workpiece processing.

[0112] like Figure 6 As shown, the first support 31 is also provided with a second through hole 312, which communicates with the first through hole 311. The second through hole 312 is located on the side of the first through hole 311 away from the rotating member 2, and the diameter of the second through hole 312 is larger than the diameter of the first through hole 311. The axial length of the shaft portion 21 on the rotating member 2 is greater than the axial length of the first through hole 311. After the first support 31 and the rotating member 2 are assembled, at least a portion of the shaft portion 21 can extend into the second through hole 312. The positioning device also includes a limiting plate 6, which can be disposed in the second through hole 312, and the diameter of the limiting plate 6 is larger than the diameter of the first through hole 311. The limiting plate 6 is fixedly connected to the shaft portion 21.

[0113] The limiting plate 6 can be fixedly connected to the shaft 21 with screws. During assembly, the first support 31 can be sleeved on the shaft 21 of the rotating part 2 through the first through hole 311, and then the limiting plate 6 can be locked onto the shaft 21 with screws. Since the axial length of the shaft 21 is greater than the axial length of the first through hole 311, after the limiting plate 6 is fixed to the shaft 21, the distance between the limiting plate 6 and the limiting part 22 on the rotating part 2 is greater than the axial length of the first through hole 311. The limiting plate 6 and the limiting part 22 on the rotating part 2 will not clamp the first support 31, thus ensuring that the first support 31 can rotate normally relative to the rotating part 2. At the same time, the limiting plate 6 and the limiting part 22 on the rotating part 2 can achieve axial limitation of the first support 31, preventing the first support 31 from wobbling significantly in the axial direction, thereby ensuring the stability of the workpiece processing.

[0114] like Figure 6 As shown, the clamping assembly 4 includes a first clamping arm 41 and a second clamping arm 42. A clamping space for setting a workpiece is provided between the first clamping arm 41 and the second clamping arm 42. Both the first clamping arm 41 and the second clamping arm 42 are slidably connected to the second support 32. By sliding the first clamping arm 41 and the second clamping arm 42 relative to the second support 32, the distance between the first clamping arm 41 and the second clamping arm 42 can be easily adjusted, thereby enabling the clamping of workpieces of different sizes.

[0115] Figure 7An exploded view of the clamping component 4 and the second support 32 in the positioning device provided in this application embodiment, as shown below. Figure 7 As shown, the first clamping arm 41 and the second clamping arm 42 are provided with slide rails 4b, and the second support 32 is provided with a slide groove 32b that is slidably connected to the slide rails 4b. The cooperation between the slide rails 4b and the slide groove 32b ensures that the first clamping arm 41 and the second clamping arm 42 can slide smoothly relative to the second support 32, preventing the first clamping arm 41 and the second clamping arm 42 from wobbling in different directions relative to the second support 32.

[0116] In some embodiments, the first clamping arm 41 and the second clamping arm 42 may be provided with a sliding groove, and the second support 32 may be provided with a slide rail that is slidably connected to the sliding groove, thereby ensuring that the first clamping arm 41 and the second clamping arm 42 slide smoothly relative to the second support 32.

[0117] like Figure 7 As shown, the positioning device also includes a lead screw 7, which comprises a first section 71 and a second section 72. Both the first section 71 and the second section 72 are provided with external threads, and the thread direction of the first section 71 and the thread direction of the second section 72 are opposite. The first section 71 is threadedly connected to the first clamping arm 41, and the second section 72 is threadedly connected to the second clamping arm 42. Since the first clamping arm 41 and the second clamping arm 42 can slide relative to the second support 32 through the aforementioned cooperation of the slide rail and slide groove, but cannot rotate relative to the second support 32, when the lead screw 7 is rotated, because the external threads on the first section 71 and the second section 72 of the lead screw have opposite directions of rotation, the first clamping arm 41 and the second clamping arm 42 can be moved closer or further apart synchronously. This allows for adjustment of the distance between the first clamping arm 41 and the second clamping arm 42, enabling the clamping of workpieces of different sizes.

[0118] The end of the first segment 71 that is away from the second segment 72 can protrude from the outer surface of the first clamping arm 41, and / or the end of the second segment 72 that is away from the first segment 71 can protrude from the outer surface of the second clamping arm 42. Thus, the part of the lead screw 7 that protrudes from the outer surface of the first clamping arm 41 or the second clamping arm 42 can be clamped by tools such as wrenches to control the rotation of the lead screw 7, thereby facilitating operation.

[0119] In one embodiment, such as Figure 6 As shown, the second support 32 can be an integrally formed structure, and the second support 32 can be fixed to the first support 31 by screws.

[0120] Figure 8 An exploded view of a positioning device provided in one embodiment of this application, as shown below. Figure 8As shown, the positioning device also includes a limiting component 10, which is slidably connected to the main body 1. The limiting component 10 is used to restrict the rotation of the rotating member 2 and the platform assembly 3, or to release the restriction on the rotating member 2 and the platform assembly 3. After adjusting the machining angle of the workpiece by rotating the platform assembly 3, the limiting component 10 can be slidably engaged with the platform assembly 3 to position the platform assembly 3, preventing it from rotating freely after the rotation angle is adjusted. Simultaneously, it prevents the rotating member 2 from rotating, ensuring stable machining of the workpiece after the angle adjustment.

[0121] like Figure 8 As shown, the limiting component 10 includes a first limiting member 101 and a second limiting member 102, which are respectively disposed on opposite sides of the platform component 3. Both the first limiting member 101 and the second limiting member 102 can slide relative to the body 1 and can limit the platform component 3 from opposite sides. For example, the first limiting member 101 and the second limiting member 102 abut against opposite sides of the platform component 3 to restrict the rotation of the platform component 3 and the rotating member 2, thereby ensuring the positional stability of the platform component 3 and the rotating member 2.

[0122] like Figure 8 As shown, the main body 1 includes a base 12 and two support plates 13, which are arranged in parallel. The base 12 is disposed between the two support plates 13, and the limiting component 10 is slidably connected to the two support plates 13. Exemplarily, the two ends of the first limiting member 101 can be slidably connected to the two support plates 13 respectively, and the two ends of the second limiting member 102 can also be slidably connected to the two support plates 13 respectively. The first limiting member 101 and the second limiting member 102 are parallel to each other.

[0123] Among them, such as Figure 8 As shown, the positioning device also includes a stop 14, which can be disposed at the end of the support plate 13 along the sliding direction of the limiting component 10, thereby limiting the limiting component 10 and preventing the limiting component 10 from disengaging from the support plate 13.

[0124] In some embodiments, the stop 14 can also slide on the body 1, and the stop 14 can abut against the limiting component 10 to restrict the movement of the limiting component 10. For example, as... Figure 8As shown, the stop 14 can slide on the support plate 13. Two stops 14 can be provided on each support plate 13. On each support plate 13, one stop 14 is located on the side of the first limiting member 101 away from the second limiting member 102, and the other stop 14 is located on the side of the second limiting member 102 away from the first limiting member 101. After the positions of the first limiting member 101 and the second limiting member 102 are adjusted, the two stops 14 can be moved to abut against the first limiting member 101 and the second limiting member 102 respectively, thereby limiting the first limiting member 101 and the second limiting member 102 and preventing them from moving freely after the position is adjusted. The stop 14 can be locked onto the support plate 13 with screws after its position is adjusted.

[0125] like Figure 8 As shown, a groove 313 is provided on the side of the first support 31, and a locking part 103 is provided on the limiting component 10, which engages with the groove 313. Exemplarily, the locking part 103 of the first limiting member 101 and the second limiting member 102 can be a thin plate, and the groove 313 on the side of the first support 31 can be a long, narrow slot. The first limiting member 101 and the second limiting member 102 can be inserted into the corresponding long slot, thereby limiting the first support 31. In other embodiments, the locking part 103 of the first limiting member 101 and the second limiting member 102 can also be a protrusion. The shape of the protrusion can be circular, elliptical, or polygonal, etc. Correspondingly, the groove 313 on the side of the first support 31 can also be circular, elliptical, or polygonal, etc., capable of engaging with the protrusion.

[0126] Figure 9 This is a schematic diagram of the structure of a positioning device provided in another embodiment of this application, as shown below. Figure 9 As shown, the positioning device also includes a positioning element 20, which is connected to the limiting component 10 or the first support 31, and is used to position the limiting component 10 on the body 1. When the limiting component 10 slides relative to the body 1 to the target position, the positioning element 20 can be operated to position the limiting component 10 on the body 1 to ensure the stability of the limiting component 10 in position.

[0127] For example, such as Figure 9 The positioning element 20 shown can be a magnet. Figure 9 In the illustrated embodiment, a magnet may be provided only on the first support 31, and the materials of the first limiting member 101 and the second limiting member 102 may be metals or magnetically conductive materials capable of attracting the magnet. This generates a mutual attractive force between the first support 31 and the first and second limiting members 101 and 102, ensuring the stability of the positions of the first and second limiting members 101 and 102.

[0128] In other embodiments, magnets may also be provided on both the first limiting member 101 and the second limiting member 102, and magnets may also be provided on the first support 31. The magnets on the first limiting member 101 and the second limiting member 102 can generate a magnetic force that attracts each other with the magnet on the first support 31. When the first limiting member 101 or the second limiting member 102 slides to the target position, the stability of the first limiting member 101 and the second limiting member 102 can be ensured by the attractive force between the magnet on the first support 31 and the corresponding magnets on the first limiting member 101 and the second limiting member 102.

[0129] Figure 10 This is a schematic diagram of the positioning device provided in another embodiment of this application. Figure 11 An exploded view of a positioning device provided in another embodiment of this application, as shown below. Figure 10 and Figure 11 As shown, the positioning device includes a body 1, which includes a base plate 11 and a base 12. The base 12 is fixed on the base plate 11, and the rotating component 2 is rotatably connected to the base 12 via a rotating shaft 5. The platform assembly 3 includes a first support 31 and a second support 32. The second support 32 can be fixed on the first support 31. The first support 31 is rotatably connected to the end of the rotating component 2 away from the base 12. A limiting plate 6 is fixedly connected to the rotating component 2. The limiting plate 6 and the rotating component 2 are located on both sides of the first support 31. The axial limiting of the first support 31 can be achieved through the cooperation of the limiting plate 6 and the rotating component 2. The clamping assembly 4 includes a first clamping arm 41 and a second clamping arm 42. The first clamping arm 41 and the second clamping arm 42 are slidably connected to the second support 32, and there is a space between the first clamping arm 41 and the second clamping arm 42 for clamping the workpiece. The positioning device also includes a limiting component 10, which includes a first limiting member 101 and a second limiting member 102. The first limiting member 101 and the second limiting member 102 are slidably connected to the base 12, and are located on opposite sides of the platform assembly 3, respectively, to limit the platform assembly 3 and prevent it from rotating freely. After the positions of the first limiting member 101 and the second limiting member 102 are adjusted, they can be locked onto the base 12 by the positioning member 20.

[0130] like Figure 11 As shown, the side of the first support 31 is provided with a groove 313, and the limiting component 10 is provided with a locking part 103, which engages with the groove 313. Exemplarily, the locking part 103 of the first limiting member 101 and the second limiting member 102 can also be a protrusion, and the shape of the protrusion can be circular, elliptical, or polygonal, etc. Correspondingly, the groove 313 on the side of the first support 31 can also be circular, elliptical, or polygonal, etc., that can cooperate with the protrusion.

[0131] exist Figure 10 In the state shown, when the workpiece is clamped in the clamping assembly 4, the top surface of the workpiece can be machined.

[0132] Figure 12 A state diagram of the positioning device provided in another embodiment of this application when machining the side of a workpiece, as shown below. Figure 12 As shown, the positioning device is composed of Figure 10 The status shown has been switched to Figure 12 In the indicated state, the rotating component 2 has rotated a certain angle relative to the base 12, for example, 90°. In this state, the side of the workpiece faces upward, thus allowing the side of the workpiece to be machined.

[0133] Figure 13 This is a state diagram of the positioning device provided in another embodiment of this application when machining the side of a workpiece. Figure 12 In the state shown, the platform assembly 3 can be switched to a position after rotating 90° relative to the rotating member 2 around the second axis C2. Figure 13 The state shown allows the other side of the workpiece to face upwards, thus enabling the processing of different sides of the workpiece without disassembling it.

[0134] Figure 14 This is a schematic diagram showing the second support 32 and the clamping assembly 4 in the positioning device provided in the embodiments of this application, from one perspective. Figure 15 for Figure 14 Exploded view, such as Figure 14 and Figure 15 As shown, the second support 32 includes a first side and a second side that are opposite to each other. The second support 32 is provided with a guide groove 323 that extends through the second support 32 from the first side to the second side. The first side and the second side of the second support 32 are two sides along its thickness direction. The first clamping arm 41 and the second clamping arm 42 are slidably disposed on the first side of the second support 32 and can move closer to or further away from each other along the extending direction of the guide groove 323.

[0135] Figure 16 A schematic diagram of the second support 32 and the clamping assembly 4 in the positioning device provided in the embodiments of this application, showing their cooperation from another perspective, as shown below. Figure 16 As shown, the second support 32 has multiple positioning parts 322 on its second side surface, which are arranged along the sliding direction of the first clamping arm 41 and the second clamping arm 42. The positioning device also includes a locking member, with the first clamping arm 41 and the second clamping arm 42 each connected to a locking member. The locking member passes through the guide groove 323 and engages with any one of the multiple positioning parts 322 to restrict the movement of the first clamping arm 41 and the second clamping arm 42.

[0136] In this embodiment, the locking member can move with the corresponding clamping arm in the guide groove 323, and the corresponding clamping arm can be locked and positioned at any position by the locking member cooperating with the positioning part 322 at the corresponding position, thereby facilitating the position adjustment of the two clamping arms and making it easier to adapt the distance between the two clamping arms to workpieces of various sizes and specifications.

[0137] Combination Figures 14 to 16 The second support 32 may include two mounting blocks 321 with a gap between them. This gap may be formed as a guide groove 323, the length direction of which is parallel to the distribution direction of the first clamping arm 41 and the second clamping arm 42.

[0138] like Figure 15 As shown, both the first clamping arm 41 and the second clamping arm 42 are provided with oblique holes 4c, the axis of which intersects the distribution direction of the first support 31 and the second support 32. In this embodiment, the first clamping arm 41 and the second clamping arm 42 are provided with sliding grooves 4a, and the second support 32 is provided with a slide rail 32a that is slidably connected to the sliding grooves 4a. The cooperation between the slide rail 32a and the sliding grooves 4a ensures that the first clamping arm 41 and the second clamping arm 42 can slide smoothly relative to the second support 32, preventing the first clamping arm 41 and the second clamping arm 42 from wobbling in different directions relative to the second support 32.

[0139] like Figure 16 As shown, each of the two mounting blocks 321 has a positioning part 322 on the side facing the first support 31. The positioning part 322 can be a slot. Each mounting block 321 can have multiple positioning parts 322, which are distributed along the length of the aforementioned guide groove 323, and the positioning parts 322 on the two mounting blocks 321 are aligned one by one.

[0140] like Figure 16 As shown, the locking component includes a pull rod 8 and a bolt 9. The pull rod 8 is engaged in the positioning part 322, and the bolt 9 passes through the inclined hole 4c and the guide groove 323 and is threadedly connected to the pull rod 8. The axial direction of the bolt 9 intersects with the distribution direction of the first support 31 and the second support 32.

[0141] During assembly, one bolt 9 can be passed through the oblique hole 4c and guide groove 323 on the first clamping arm 41 and pre-tightened to the corresponding pull rod 8 via a threaded connection. Similarly, another bolt 9 can be passed through the oblique hole 4c and guide groove 323 on the second clamping arm 42 and pre-tightened to the corresponding pull rod 8 via a threaded connection. The distance between the first clamping arm 41 and the second clamping arm 42 is adjusted according to the workpiece to be clamped, so that the two pull rods 8 engage with the corresponding positioning part 322. Then, the bolt 9 can be tightened, and the tension between the bolt 9 and the corresponding pull rod 8 secures the corresponding first clamping arm 41 and second clamping arm 42 to the mounting block 321, simultaneously clamping the workpiece. Then, the second support 32 can be fixed as a whole to the first support 31.

[0142] Figure 17 for Figure 14 The sectional view at point AA, as shown Figure 17 As shown, since the axial direction of the inclined hole 4c intersects with the distribution direction of the first support 31 and the second support 32, when the bolt 9 is installed in the inclined hole 4c, the axial direction of the bolt 9 is the same as the axial direction of the inclined hole 4c. That is, the axial direction of the bolt 9 intersects with the distribution direction of the first support 31 and the second support 32. The bolt 9 is inclined and locked with the corresponding tie rod 8. The direction of the force F between the bolt 9 and the tie rod 8 is at an angle to the sliding direction of the first clamping arm 41 and the second clamping arm 42. Therefore, when the bolt 9 is tightened with the tie rod 8, the bolt 9 will generate a component force F1 on the corresponding first clamping arm 41 and the second clamping arm 42. The direction of this component force F1 is parallel to the sliding direction of the first clamping arm 41 and the second clamping arm 42 relative to the second support 32. Thus, the first clamping arm 41 and the second clamping arm 42 can be clamped with this component force F1 to ensure the stability of the workpiece during the processing.

[0143] As explained above, such as Figure 11 As shown, the first limiting member 101 and the second limiting member 102 can be slidably connected to the base 12. Optionally, both the first limiting member 101 and the second limiting member 102 can be slidably connected to the base 12 through the cooperation of a sliding groove and a sliding rail. For example, the first limiting member 101 and the second limiting member 102 are provided with sliding grooves, and the base 12 is provided with a sliding rail; or, the first limiting member 101 and the second limiting member 102 are provided with sliding rails, and the base 12 is provided with sliding grooves. This ensures the stability of the sliding of the first limiting member 101 and the second limiting member 102 relative to the base 12.

[0144] As explained above, after the positions of the first limiting member 101 and the second limiting member 102 are adjusted, the positioning member 20 can lock the first limiting member 101 and the second limiting member 102 onto the base 12. Figure 11As shown, the positioning element 20 can be a screw, and both the first limiting element 101 and the second limiting element 102 can be provided with threaded holes, which the screw can engage with. After the position of the first limiting element 101 or the second limiting element 102 is adjusted, the screw can be rotated to pass through the threaded hole and abut against the base 12, thereby achieving the positioning of the first limiting element 101 or the second limiting element 102.
