However, the following embodiments are only the preferred embodiments of the present utility model and not all of them. Based on the embodiments in the embodiments, other embodiments obtained by those skilled in the art without creative efforts all fall within the protection scope of the present utility model.

[0022] The following specifically describes a flat ejector pin fixture according to an embodiment of the present utility model with reference to the accompanying drawings.

[0023] Embodiment 1

[0024] For ease of understanding, please refer to Figures 1 to 3 , an embodiment of a flat ejector pin fixture provided by the present utility model, which includes a base 1. A pressurizing component capable of moving, a lower clamping member 3, and an upper clamping member 4 are provided on the base 1. The pressurizing component includes a rotating rotating arm 7 and an inverted "V"-shaped precise pressurizing member 8. The precise pressurizing member 8 rotates on the rotating arm 7, and the rotating arm 7 is supported on the tops of the mutually butted lower clamping member 3 and upper clamping member 4.

[0025] The lower clamping member 3 includes a lower housing 31 and a lower clamping block 32. The lower clamping block 32 is fixedly connected in the lower housing 31. The upper clamping member 4 includes an upper housing 41 and an upper clamping block 42. The upper clamping block 42 is fixedly connected in the upper housing 41. And the materials of the lower clamping block 32 and the upper clamping block 42 are both made of high-speed steel.

[0026] It should be noted that the top of the base 1 installs and supports the entire pressurizing component, the lower clamping member 3, and the upper clamping member 4. Among them, the lower clamping member 3 is composed of a lower housing 31 and a lower clamping block 32 embedded therein, while the upper clamping member 4 includes an upper housing 41 and an upper clamping block 42 fixed therein. The clamping blocks of both are made of high-speed steel materials to ensure good wear resistance and compressive strength. Through the inverted "V" shape structure setting of the precise pressurizing member 8, uniform pressure can be applied during rotation, avoiding workpiece damage caused by local overpressure and improving processing stability.

[0027] In an alternative embodiment: The pressurizing component further includes a slide rail 5 and a sliding frame 6. The slide rail 5 is fixedly connected to one side of the top of the base 1, and the sliding frame 6 is slidably matched on the slide rail 5.

[0028] It should be noted that the slide rail 5 is fixed to one side of the top of the base 1, and the sliding frame 6 can slide smoothly on the slide rail 5, which is convenient for quick disassembly after the fixture is clamped.

[0029] In an alternative embodiment: The rotating arm 7 is rotatably connected to the top of the sliding frame 6 through a rotating shaft. An installation groove 71 is opened at the top of the rotating arm 7, and the precise pressurizing member 8 is rotatably connected in the installation groove 71.

[0030] It should be noted that the rotating arm 7 is installed on the top of the sliding carriage through a rotating shaft, and an installation groove 71 is provided on its top. The precise pressing member 8 can rotate freely within the installation groove 71, forming a flexible inverted "V" - shaped pressure point to achieve precise positioning and uniform pressing of the workpiece.

[0031] In an alternative embodiment: One side of the top of the base 1 is fixedly connected with a screw rod 9, and a groove for installing the screw rod 9 is provided at the position where the rotating arm 7 contacts the screw rod 9. A locking nut 10 is fixedly installed on the screw rod 9, and the locking nut 10 supports on the top of the rotating arm 7.

[0032] It should be noted that a screw rod 9 is fixedly installed on one side of the base, which cooperates with the groove on the rotating arm 7. By adjusting the locking nut 10, the user can finely adjust the position of the rotating arm 7, and thus adjust the pressure of the precise pressing member 8 on the workpiece. The rotating arm 7 realizes stable pressing and clamping through the precise pressing member 8, and also ensures that the pressure remains stable during the operation process.

[0033] In an alternative embodiment: Matching sliding grooves are provided on both sides of one end of the lower housing 31 and the lower clamping block 32, and a precise positioning column 13 is slidably connected in the matching sliding grooves. The bottom of the lower clamping member 3 is fixedly connected with a positioning seat 2, a fitting groove 21 is provided at the bottom of the positioning seat 2, and a sliding strip 11 is fixedly connected to the top of the base 1, and the positioning seat 2 is slidably connected to the sliding strip 11 in a matching manner.

[0034] It should be noted that matching sliding grooves are provided on both sides of one end of the lower housing 31 and the lower clamping block 32, with a precise positioning column 13 inside, which can ensure precise positioning provided by the lower clamping member 3 and the upper clamping member 4 when the workpiece is placed. At the same time, the bottom of the lower clamping member 3 is slidably connected to the sliding strip 11 on the top of the base 1 through the positioning seat 2, enabling the entire lower clamping member 3 to slide and adjust its position along the sliding strip 11 as needed, further enhancing the flexibility and versatility of the fixture.

[0035] Working principle: First, place the fixture on the workbench to ensure the stability of the base 1. The lower clamping member 3 is slidably connected to the slide bar 11 on the top of the base through the positioning seat 2 at its bottom and adjusted to a suitable position according to actual needs. The upper clamping member 4 is directly located above the lower clamping member, and the two together form a closed space for accommodating the workpiece to be processed. The workpiece is placed in the space between the lower clamping member 3 and the upper clamping member 4. By using the sliding grooves on the sides of the lower housing 31 and the lower clamping block 32 and the built-in precise positioning posts 13, ensure that the workpiece is in an accurate position before processing and guarantee the accuracy. The operator flips the rotating arm 7 and supports the precise pressing member 8 on the rotating arm 7 directly above the upper clamping member 4. Due to its inverted "V" shape design, the precise pressing member 8 at the top of the rotating arm can apply a uniform and adjustable pressure to the workpiece during rotation. At this time, the groove body at one end of the rotating arm 7 is located on the side wall of the screw 9, and then rotate the locking nut 10 to finely adjust and finally lock the position of the rotating arm 7, so that the precise pressing member 8 can apply pressure to the surface of the upper clamping member 4 to achieve a comprehensive and precise clamping, and the workpiece remains stable without slipping, avoiding machining errors. After clamping, the locking nut 10 can be rotated to loosen. When the locking nut 10 disengages the acting force on the rotating arm 7, the rotating arm 7 slides on the slide rail 5 through the slide carriage 6 until it gets out of the restricted range of the locking nut 10 on the rotating arm 7. Therefore, the rotating arm 7 can be opened to operate the lower clamping member 3 and the upper clamping member 4.

[0036] As described above, the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
