[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] First embodiment:

[0026] See Figures 1-2 As shown, this utility model provides a novel positioning fixture, including a base plate 1, which is used to support the workpiece to be processed. A support frame 2 is provided on the upper surface of the base plate 1. The support frame 2 is cuboid and is bolted to the surface of the base plate 1. Two corresponding clamping structures 3 are rotatably connected to the movable end of the support frame 2. The support frame 2 is provided with a driving component 4 that drives the two clamping structures 3 to rotate in opposite directions.

[0027] The clamping structure 3 includes an arc frame 301, with corresponding inner arc surfaces and an inner template 303 matching the workpiece to be processed on the inner side. The movable end of the arc frame 301 is provided with a protrusion 302, and the base plate 1 is provided with a locking assembly 5 for limiting the protrusion 302.

[0028] When the device is in use, the drive assembly 4 drives the two clamping structures 3 to rotate, so that the two clamping structures 3 are in an open state. The two inner templates 303 move away from each other, and the workpiece is placed between the two inner templates 303. The drive assembly 4 drives the two clamping structures 3 to rotate in opposite directions, so that the two inner templates 303 close to each other can press the workpiece. In order to further ensure the fixing effect of the workpiece, the locking assembly 5 is used to limit and fix the protrusion 302, thereby fixing the movable end of the arc frame 301, thus achieving the overall fixing of the workpiece and the clamping structure 3. After the processing is completed, the locking assembly 5 is released from fixing the two protrusions 302. The drive assembly 4 drives the two clamping structures 3 to rotate in opposite directions, so that the two inner templates 303 move away from each other, and the limiting fixation of the workpiece can be released. The device is simple and convenient to operate, and the installation and disassembly of the workpiece are more convenient. It also fixes the workpiece more firmly and is conducive to processing workpieces with cylindrical and square cross sections. It is highly practical.

[0029] In a preferred embodiment, the inner template 303 is bolted to the arc frame 301, and the outer wall of the inner template 303 matches the inner wall of the arc frame 301. The inner template 303 is fixed by bolts, which facilitates the installation and replacement of the inner template 303. The inner wall of the inner template 303 is V-shaped, which can help to position components with square and circular cross-sections.

[0030] The second embodiment differs from the first embodiment in that:

[0031] Locking assembly 5 includes a second electric push rod 501, the telescopic end of which is connected to a portal frame 502, and the portal frame 502 is correspondingly arranged with the protrusion 302.

[0032] The protrusions 302 are right-angled trapezoids with their right-angled ends corresponding to each other. Their small end faces extend towards the inside of the gantry frame 502. There is a gap between the right-angled ends of the protrusions 302. After the second electric push rod 501 extends, the gantry frame 502 moves toward the protrusions 302. The inner end of the gantry frame 502 corresponds to the protrusions 302. Then, the small end of the protrusions 302 enters the gantry frame 502 first for guidance. As the gantry frame 502 gradually moves toward the protrusions 302, the protrusions 302 can be pressed together by the side walls of the gantry frame 502. Because there is a gap between the protrusions 302, the protrusions 302 can gradually approach each other until the parts are pressed together, resulting in a good fixing effect on the parts.

[0033] The inner wall of the sealing end of the portal frame 502 is provided with a pressure sensor 503 corresponding to the protrusion 302. The base plate 1 is provided with a battery and an indicator light that are electrically connected to the pressure sensor 503. When the two protrusions 302 are fixed by the portal frame 502, the inner template 303 clamps the parts. After the pressure sensor 503 contacts the protrusion 302, the protrusion 302 is subjected to the pressure of the protrusion 302. When the indicator light is lit, it indicates that the parts are completely fixed, so that machining operations can be performed.

[0034] Furthermore, the bottom of the protrusion 302 is provided with a slider, and the base plate 1 is provided with a sliding groove 101 corresponding to the slider. The sliding groove 101 is used to guide the slider and assist the smooth rotation of the protrusion 302.

[0035] The third embodiment differs from the first embodiment in that:

[0036] The drive assembly 4 includes a sliding sleeve 402 that slides on the outside of the support frame 2. A rotating arm 401 is rotatably connected between the sliding sleeve 402 and the clamping structure 3. The support frame 2 is fixed with a first electric push rod 404 that pushes the sliding sleeve 402 to slide on the outside of the support frame 2. After the first electric push rod 404 extends or retracts, it can assist the sliding sleeve 402 to slide on the outside of the support frame 2, thereby pulling the two rotating arms 401 to rotate and pull the clamping structure 3. This assists the two clamping structures 3 in opening or closing operations. When the two clamping structures 3 are open, it is convenient to place and remove parts. When the two clamping structures 3 are closed, they can clamp and fix the parts, which can assist the machine tool in processing.

[0037] Preferably, the support frame 2 has an internal cavity, in which the first electric push rod 404 is installed. The surface of the support frame 2 has a guide groove 201 extending along the sliding direction of the sliding sleeve 402. The telescopic end of the first electric push rod 404 is connected to a sliding seat 403 that slides in cooperation with the guide groove 201. The sliding seat 403 passes through the guide groove 201 and is connected to the sliding sleeve 402. In this way, the support frame 2 supports the first electric push rod 404. By sliding the sliding seat 403 and the support frame 2, the sliding seat 403 and the sliding sleeve 402 can be guided, so that the sliding sleeve 402 can slide smoothly. Moreover, the cross-section of the sliding seat 403 is trapezoidal, which can increase the connection area between the first electric push rod 404 and the sliding seat 403 and improve the connection stability between the first electric push rod 404 and the sliding seat 403.

[0038] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
