DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] The utility model provides Figure 1 - Figure 4 A manual positioning clamp is shown, comprising a fixed seat 1, the inner wall of which is rotatably provided with a rotating seat 2, and the surface of the rotating seat 2 is provided with a positioning clamp part 3 for positioning and clamping the object. The positions of multiple positioning clamps 301 can be adjusted by manually pushing the rotating rod 444 to slide left and right, so that it can fit tightly against the outer side of the special-shaped part. The operation method is simple and intuitive, which not only improves the stability of the clamping, but also greatly simplifies the operation process.

[0022] The positioning fixture part 3 includes a positioning fixture 301, which is slidably set on the surface of the fixed seat 1. There are multiple arc grooves 302 arranged at equal intervals on the rotating seat 2. Sliding grooves 303 are equidistantly opened on the surface of the fixed seat 1. The positioning fixture 301 is slidably connected to the inner wall of the arc groove 302. A limiting rod 304 is set at the bottom of the positioning fixture 301, and the limiting rod 304 is slidably connected to the inner wall of the arc groove 302.

[0023] An escape groove 333 is provided on the outer side of the fixed seat 1, and a rotating rod 444 is provided on the outer side wall of the rotating seat 2 to facilitate the staff to rotate the rotating disk.

[0024] When the object needs to be clamped, the rotating rod 444 is pushed to slide rightward by hand, and the rotating seat 2 rotates to push the limiting rod 304 to slide along the arc groove 302. Under the influence of the arc groove 302, the limiting rod 304 slides forward along the inner wall of the sliding groove 303 with the positioning fixture 301, so that the positioning fixture 301 clamps the object;

[0025] When the push rod 444 moves to the left, the rotating seat 2 rotates to push the limiting rod 304 to slide along the arc groove 302, so that the limiting rod 304 moves the positioning fixture 301 backward along the inner wall of the sliding groove 303, thereby releasing the positioning fixture 301 from contact with the object.

[0026] The utility model also provides a manual positioning device, including a storage box 400, which is fixedly arranged on the top of the positioning fixture 301. The storage box 400 is provided with a positioning device 4 for positioning the object. When the positioning fixture 301 clamps the special-shaped part, the positioning part 403 can be flexibly adjusted according to the difference in shape, size and other requirements of the special-shaped part and effectively position it, so as to adapt to the processing of workpieces of different types and specifications, and save the time and cost of fixture replacement.

[0027] The positioning device 4 includes a sliding plate 401, which is slidably set on the inner wall of the storage box 400. A spring 402 is set on the inner wall of the storage box 400. One end of the spring 402 is fixed to the sliding plate 401. The inner wall of the storage box 400 has multiple positioning members 403 that are equidistantly slidably set. A rotating bead 404 is slidably set on the side of the inner wall of the storage box 400 away from the spring 402, and the side of the positioning member 403 close to the rotating bead 404 is in squeeze contact with the rotating bead 404.

[0028] An anti-slip sleeve 407 is provided on one side of the positioning member 403 away from the rotating bead 404 to enhance the friction between the positioning member 403 and the special-shaped member when in contact, thereby ensuring a close fit and a firm clamping between the two, and also reducing the wear of the positioning member 403 on the outer side of the special-shaped member;

[0029] When the positioning fixture 301 contacts the object, after the positioning member 403 contacts the object, due to the different shapes of the outer sides of the objects, each positioning member 403 will slide toward the inner wall of the storage box 400 to varying degrees according to the actual shape of the object. During this process, the positioning member 403 will squeeze the rotating bead 404, and the rotating bead 404 will further squeeze the sliding plate 401 after being squeezed. While being squeezed, the sliding plate 401 will compress the spring 402 to cause it to deform. When the positioning member 403 completes the initial squeezing and adaptation of the object, the spring 402 begins to reset. During the resetting of the spring 402, the sliding plate 401 will be pushed by the spring 402, thereby pushing the rotating bead 404 to reversely squeeze the positioning member 403. After being squeezed by the sliding plate 401, the positioning member 403 will reversely squeeze the outer side of the object, thereby making it possible to position the outer side of the special-shaped part.
