Moreover, the specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.

[0037] As Figure 1 and Figure 2 shown, an embodiment of the present application provides an adjustable-angle machining fixture. The adjustable-angle machining fixture includes a base 102, a clamping assembly, and a locking assembly. Among them, the clamping assembly is used to clamp the workpiece 101. The clamping assembly together with the workpiece 101 rotates relative to the base 102, so as to adjust the angle of the workpiece 101. The locking assembly locks the workpiece 101 at the adjusted angle, facilitating the staff to perform machining at different angles and improving the machining efficiency. At the same time, the machining position of the workpiece 101 on the clamping assembly is close to the rotation center of the clamping assembly, so that the height of the workpiece 101 is less affected during the rotation of the clamping assembly, without the need for the staff to significantly change their working posture, improving the comfort of the staff and further ensuring the machining efficiency.

[0038] In addition, the workpiece 101 adapted to the adjustable-angle machining fixture of the present application is formed into a plate-like structure. Specifically, the workpiece 101 includes a board.

[0039] In some examples, the base 102 is used to support the clamping assembly and the locking assembly. Among them, the base 102 is formed into a plate-like structure and is placed on a device such as a workbench with a larger-area board surface to improve the overall stability of the fixture by increasing the contact area. It can be understood that during the working process of the fixture, the position of the base 102 is fixed.

[0040] Furthermore, as Figure 3 shown, the clamping assembly is rotatably connected to the base 102. The clamping assembly includes a clamping unit. The clamping unit is used to clamp the workpiece 101 so that the workpiece 101 is positioned on the clamping assembly. When the clamping assembly rotates relative to the base 102, the workpiece 101 also rotates together, thereby adjusting the angle of the workpiece 101.

[0041] Specifically, when the base 102 is placed approximately horizontally, when the clamping assembly fits against the base 102, the clamping assembly is also approximately horizontal; during the process of the clamping assembly rotating relative to the base 102, the clamping assembly moves away from the base 102, and the angle formed between the clamping assembly and the base 102 continuously changes, and the angle of the workpiece 101 also changes accordingly.

[0042] It should be noted that the clamping assembly has a certain length. When the position where the clamping unit clamps the workpiece 101 is far from the position where the clamping assembly is rotatably connected to the base 102, since the workpiece 101 is far from the rotation center of the clamping assembly, as the clamping assembly rotates, the height change range of the workpiece 101 is relatively large. That is, when the workpiece 101 is at different angles, there is a large height difference. Then, when the worker processes the workpiece 101 at different angles, it is necessary to greatly adjust the working posture, which is likely to cause discomfort to the worker and thus reduce the processing efficiency.

[0043] In this application, the position where the clamping unit clamps the workpiece 101 is close to the position where the clamping assembly is rotatably connected to the base 102. Since the workpiece 101 is close to the rotation center of the clamping assembly, as the clamping assembly rotates, the height change range of the workpiece 101 is relatively small. Then, when the worker processes the workpiece 101 at different angles, only a small adjustment of the working posture is required, or even no adjustment of the working posture is needed, so as to avoid affecting the processing efficiency of the worker.

[0044] In some examples, the clamping unit includes a first fixing member 201 and a moving member 202. The first fixing member 201 and the moving member 202 are generally formed in a block structure. The position of the first fixing member 201 in the clamping assembly is fixed, while the moving member 202 can move in the clamping assembly.

[0045] Among them, the moving member 202 is arranged in parallel with the first fixing member 201, and the moving member 202 moves closer to or away from the first fixing member 201. During the process of clamping the workpiece 101 by the clamping unit, the moving member 202 first moves away from the first fixing member 201, increasing the distance between the moving member 202 and the first fixing member 201, so as to facilitate placing the workpiece 101 on the side of the first fixing member 201 close to the moving member 202, making the workpiece 101 located between the moving member 202 and the first fixing member 201; after the workpiece 101 is placed, the moving member 202 gradually moves closer to the first fixing member 201, that is, gradually moves closer to the workpiece 101 until the moving member 202 abuts against the workpiece 101, then the moving member 202 and the first fixing member 201 form a clamping action on the workpiece 101, and the workpiece 101 is positioned.

[0046] Furthermore, since the moving member 202 makes a clamping action by moving, and the position of the first fixing member 201 is fixed, the position of the first fixing member 201 determines the clamping position of the workpiece 101 in the clamping assembly. Therefore, the first fixing member 201 is close to the position where the clamping assembly is rotatably connected to the base 102, so as to ensure that the workpiece 101 is clamped at a position close to the rotation center of the clamping assembly, and the height change range of the workpiece 101 during the rotation of the clamping assembly is relatively small.

[0047] In addition, for workpieces 101 with different structures and shapes, the shapes of the moving member 202 and the first fixing member 201 can be set according to the actual situation of the workpiece 101 to ensure that the workpiece 101 is stably clamped between the moving member 202 and the first fixing member 201.

[0048] In some examples, the clamping assembly further includes a driving unit that provides the driving force for the movement of the moving member 202 and also provides the clamping force for the moving member 202 against the workpiece 101.

[0049] Among them, the driving unit drives the moving member 202 to move, so that the moving member 202 approaches the first fixing member 201 or moves away from the first fixing member 201.

[0050] In some examples, the driving unit includes a second fixing member 203 and a screw 204. The second fixing member 203 is generally formed in a block structure. The second fixing member 203, the moving member 202, and the first fixing member 201 are arranged in parallel, and there is a gap between the second fixing member 203 and the first fixing member 201. The moving member 202 is located between the second fixing member 203 and the first fixing member 201.

[0051] Among them, the position of the second fixing member 203 in the clamping assembly is fixed, and a nut 206 is fixedly arranged on the second fixing member 203. The nut 206 is threadedly connected to the screw 204, so that the second fixing member 203 and the screw 204 form a screw-nut structure.

[0052] Furthermore, the screw 204 is rotatably connected to the moving member 202. Here, the rotational connection means that the screw 204 can freely rotate on the moving member 202 but always remains connected to the moving member 202 to ensure that the screw 204 can continuously exert a force on the moving member 202.

[0053] It can be understood that the moving member 202 is provided with a connecting member, and the end of the screw 204 close to the moving member 202 is rotatably connected to the moving member 202 through the connecting member. Specifically, the connecting member includes a bearing. The end of the screw 204 close to the moving member 202 is inserted into the inner edge of the bearing and achieves an interference fit, and the outer edge of the bearing is fixed to the moving member 202. Among them, the bearing can be embedded inside the moving member 202, and a sealing piece is installed at the insertion opening of the moving member 202 to prevent the bearing from accidentally detaching from the moving member 202.

[0054] During use, since the position of the nut 206 in the clamping assembly is fixed, the screw 204 rotates under the limitation of the nut 206. During the rotation process, the screw 204 will move axially, thereby driving the moving part 202 to move accordingly. At the same time, by setting the axial direction of the screw 204 to limit the moving direction of the moving part 202, the moving part 202 reciprocates between the first fixing part 201 and the second fixing part 203, and the first fixing part 201 and the second fixing part 203 define the moving limit positions of the moving part 202.

[0055] In addition, for the convenience of the staff to rotate the screw 204, a handle 205 is provided at the end of the screw 204 away from the moving part 202, and the handle 205 is detachably connected to the screw 204 for easy replacement.

[0056] As Figure 3 shown, in some examples, the clamping assembly further includes a rotating seat 207, and the rotating seat 207 is generally formed in a plate-like structure. Both the clamping unit and the driving unit are connected to the rotating seat 207. When the rotating seat 207 rotates, the workpiece 101 clamped by the clamping unit is adjusted in angle.

[0057] Among them, the clamping assembly further includes a rotating member 208, and the rotating member 208 connects the rotating seat 207 and the base 102, enabling the rotating seat 207 and the base 102 to be rotatably connected. It can be understood that the rotation center of the clamping assembly relative to the base 102 is located at the rotating member 208.

[0058] At the same time, on the premise that the rotating member 208 connects the rotating seat 207 and the base 102, the rotating member 208 is located close to the first fixing part 201, ensuring that the first fixing part 201 is close to the rotation center of the clamping assembly, that is, ensuring that the clamping position of the workpiece 101 is close to the rotation center of the clamping assembly.

[0059] Furthermore, the rotating member 208 includes a hinge. The two connecting parts of the hinge are fixedly connected to the rotating seat 207 and the base 102, and the rotating shaft of the hinge is the rotation center of the clamping assembly. Specifically, one connecting part of the hinge fits on the side edge of the rotating seat 207, and the other connecting part of the hinge fits on the plate surface of the base 102 facing the rotating seat 207, so that the rotating shaft of the hinge is located at the junction position of the rotating seat 207 and the base 102. At this time, during the process of the rotating seat 207 rotating away from the base 102, there is no situation where each position of the rotating seat 207 continues to approach the base 102, avoiding rotational interference between the rotating seat 207 and the base 102. In addition, setting the edge of the rotating seat 207 connected to the hinge as an arc can also avoid interference between the rotating seat 207 and the base 102 during the rotation process.

[0060] As Figure 4 andFigure 5 As shown, in some examples, to further guide the movement process of the moving part 202, the moving part 202 includes a first sliding part 301, and the first sliding part 301 is connected to the main body part of the moving part 202. The rotating seat 207 is provided with a first installation groove 302, and the first installation groove 302 extends from the first fixing part 201 to the second fixing part 203. The first sliding part 301 is embedded in the first installation groove 302 and is slidably connected to the inner wall of the first installation groove 302, so that the first sliding part 301 slides along the first installation groove 302, and the moving part 202 also moves along the first installation groove 302.

[0061] In some examples, the moving part 202 further includes a second sliding part 303. The second sliding part 303 is connected to the first sliding part 301, and the first sliding part 301 is located between the main body part of the moving part 202 and the second sliding part 303. The base 102 is provided with a second installation groove 304, and the second installation groove 304 extends from the first fixing part 201 to the second fixing part 203. The second sliding part 303 is embedded in the second installation groove 304 and is slidably connected to the inner wall of the second installation groove 304.

[0062] Furthermore, the width of the second sliding part 303 is greater than the width of the first sliding part 301. It can be understood that the width of the first installation groove 302 matches the width of the first sliding part 301, and the width of the second installation groove 304 matches the width of the second sliding part 303, so the width of the second installation groove 304 is greater than the width of the first installation groove 302. Therefore, the rotating seat 207 is stuck between the main body part of the moving part 202 and the second sliding part 303. On the premise of ensuring the sliding connection between the moving part 202 and the rotating seat 207, it is avoided that the first sliding part 301 disengages from the first installation groove 302, that is, the moving part 202 is prevented from disengaging from the rotating seat 207. As the clamping assembly rotates, the second sliding part 303 can disengage from the second installation groove 304.

[0063] Specifically, the contact surfaces between the moving part 202 and the rotating seat 207 need to be polished smoothly to reduce friction and ensure smooth sliding connection. Similarly, the contact surfaces between the moving part 202 and the base 102 also need to be polished smoothly.

[0064] In some examples, after the clamping assembly rotates to the required position, the locking assembly locks the position of the clamping assembly, thereby maintaining the workpiece 101 at the adjusted angle, which is convenient for the staff to process at this angle.

[0065] Among them, the locking component includes a guiding component 501 and a locking component 504. The base 102 is fixedly provided with a supporting component 503. The guiding component 501 is connected to the supporting component 503 and thus fixed to the base 102. The guiding component 501 has a certain length. After the clamping component rotates to the required position, the locking component 504 connects the clamping component to the guiding component 501, thereby locking the position of the clamping component. It can be understood that when the clamping component rotates to different positions, the locking component 504 connects the clamping component to different positions of the guiding component 501. Specifically, the guiding component 501 extends along the rotation direction of the clamping component.

[0066] In some examples, the guiding component 501 is provided with a guiding groove 502, and the guiding groove 502 also extends along the rotation direction of the clamping component. After the clamping component rotates to the required position, the locking component 504 passes through the corresponding position of the guiding groove 502 and connects the clamping component. Under the fastening action of the locking component 504, the clamping component is connected to the guiding component 501.

[0067] Among them, since the locking component 504 can connect the clamping component at any position within the guiding groove 502, the guiding groove 502 has a limiting effect on the rotation range of the clamping component. Therefore, the length of the guiding groove 502 needs to be set according to the stroke of the clamping component.

[0068] Specifically, as Figure 6 and Figure 7 shown, when the locking component 504 connects the clamping component at the end of the guiding groove 502 close to the base 102, the clamping component is in the first limit position; as Figure 8 and Figure 9 shown, when the locking component 504 connects the clamping component at the end of the guiding groove 502 far from the base 102, the clamping component is in the second limit position. Then the clamping component can be positioned at any position between the first limit position and the second limit position.

[0069] In some examples, the clamping component further includes a positioning component 505. The positioning component 505 is connected to the rotating seat 207 or connected to the second fixing component 203. The positioning component 505 is provided with a jack. The locking component 504 passes through the guiding groove 502 and inserts into the jack to realize the connection between the guiding component 501 and the clamping component.

[0070] Among them, the size of the insertion end of the locking component is smaller than the width of the guiding groove 502, which is convenient for passing through the guiding groove 502. At the same time, the size of the clamping end of the locking component is larger than the width of the guiding groove 502, so that the clamping end of the locking component is stuck on the side of the guiding component 501 away from the clamping component. Then the clamping end of the locking component and the positioning component 505 clamp the guiding component 501.

[0071] Specifically, the locking component includes a locking screw. The jack is provided with internal threads, and the locking screw is inserted into the jack through threaded connection, thereby achieving the fastening effect.

[0072] In the actual implementation process, rotate the screw rod 204 counterclockwise to drive the moving component 202 away from the first fixed component 201, and then rotate the screw rod 204 clockwise to drive the moving component 202 closer to the first fixed component 201. During this process, the workpiece 101 is clamped between the two, positioning the workpiece 101 in the clamping assembly; when the angle of the workpiece 101 needs to be adjusted, first loosen the locking component 504 and rotate the clamping assembly. When the clamping assembly is adjusted to the required position, tighten the locking component 504 to connect the clamping assembly to the guiding component 501, and the workpiece 101 is maintained at the adjusted angle.

[0073] The workpiece 101 is clamped at a position close to the rotation center of the clamping assembly. During the rotation process of the workpiece 101, only a small height change occurs, avoiding the need for the staff to make large adjustments to their working postures and ensuring the processing efficiency.

For example, depending on the functions / operations involved, two consecutive blocks shown may actually be executed substantially simultaneously or the blocks can sometimes be executed in the reverse order.
