[0016] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0017] All features disclosed in this specification, or all steps in all disclosed methods or processes, may be combined in any way, except for mutually exclusive features and / or steps.

[0018] Any feature disclosed in this specification (including any appended claims, abstract, and drawings) may be replaced by other equivalent or similar features, unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is merely one example of a series of equivalent or similar features.

[0019] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the present invention discloses a quick clamping and positioning fixture structure for a horizontal milling machine, comprising a worktable 1 mounted on the horizontal milling machine and multiple fixtures mounted on the worktable 1. Each fixture includes a slider 3, a movable seat 5, and a clamping seat 6. The sliders 3 are all slidably disposed in the T-slots 2 of the worktable 1. One end of each slider 3 is bent to form a fixing part 4. The fixing parts 4 are all flatly disposed on the surface of the worktable 1. The movable seats 5 are all disposed on the surface of the fixing parts 4, and the clamping seats 6 are all disposed on the surface of the movable seats 5.

[0020] In this embodiment, each of the fixed parts 4 is provided with an adjustment groove 11, and each of the inner sides of the movable seat 5 is provided with an adjustment block 12 opposite to the adjustment groove 11. The adjustment blocks 12 are slidably disposed in the adjustment groove 11. One end of each of the fixed parts 4 is provided with a screw hole communicating with the adjustment groove 11. Each screw hole is threaded with a screw rod 7. One end of each screw rod 7 abuts against the adjustment block 12, and the other end is disposed on the outside and is provided with a rotating block 8.

[0021] In this embodiment, a half rod is installed at one end of both the movable seat 5 and the clamping seat 6, and a stud 10 is formed by combining adjacent half rods. Nuts 9 that press the fixed seat and the movable seat 5 together are threadedly connected to the outside of the stud 10.

[0022] In this embodiment, the cross-sections of both the adjusting groove 11 and the adjusting block 12 are trapezoidal, and one end of the adjusting groove 11 is open. Because one end of the adjustment slot is open, the movable seat can move outward along the opening of the adjustment slot until the adjustment block disengages from the adjustment slot. This allows the movable seat and clamping seat to be replaced, and allows the installation of other movable seats and clamping seats of different sizes that match the adjustment block, thus increasing the efficiency of replacement.

[0023] In this embodiment, the sliders 3 are all T-shaped and match the T-slots 2 on the worktable 1, so that the fixture can only move back and forth along the T-slots, thus preventing it from detaching from the worktable.

[0024] In this embodiment, one end of the clamping seat 6 is flush with one end of the movable seat 5, and the other end of both protrudes from the movable seat 5. Multiple hinges are installed between the clamping seat 6 and the movable seat 5, and the other end of the clamping seat can be fixed by the hinges.

[0025] In this embodiment, all rotating blocks 8 are hexagonal in shape, which makes the rotating blocks match the nuts, allowing wrenches or other equipment to be fitted onto the outside of the rotating blocks, thus facilitating the rotation of the screw.

[0026] In use, the fixture can be slidably installed in the T-slot of the worktable via a slider. After being moved into place, the rotating block can be rotated by a wrench or automatic equipment. The rotation of the rotating block drives the screw, which moves along the screw hole. The movement of the screw can push the adjusting block, the moving seat, and the clamping seat. The clamping seat can quickly complete the clamping operation of the workpiece by approaching each other. The directional pressure generated during the clamping process can make the slider and the T-slot come into close contact. The mutual force can complete the clamping of the workpiece and the fixation of itself. As attached Figure 5 As shown, when changing to a taller workpiece, the nut can be removed, and the clamping seat can be raised upwards around the hinge until the clamping seat is set vertically. Since one end of the clamping seat protrudes from the moving seat, after rotation, the excess end can rest against the end faces of the moving seat and the fixed part. Therefore, after the vertical pressing seat contacts the workpiece, the lower part can be pressed by the fixed part and the moving seat to ensure the stability of the clamping seat after it is vertical. The height of the clamping seat increases the contact area with the workpiece to ensure its stability.

[0027] 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 changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
