[0002] The machining fixture for the inner frame of the hook tail frame refers to a special tool specifically designed for machining the inner frame component of the hook tail frame. It is usually designed according to the structural characteristics and machining requirements of the inner frame of the hook tail frame, aiming to improve machining accuracy and efficiency. It can ensure the stable positioning of the inner frame of the hook tail frame during machining. By using the machining fixture, the batch and high-precision production of the inner frame of the hook tail frame can be realized, meeting the high requirements for the quality and efficiency of parts in mechanical manufacturing and industrial production.

[0003] Chinese Patent Publication No. CN105537996B discloses a method for machining the inner bend of the tail of a hook tail frame, comprising: adjusting the horizontal machining reference of the hook tail frame using a first pad and a second pad; positioning the hook tail frame using two locating pins and a T-shaped locating block; and fixing the tail and front-middle parts of the hook tail frame using a first clamping mechanism and a second clamping mechanism. This method has the advantages of simple process, convenient tooling and fixture installation, accurate positioning, and high machining precision, ensuring machining quality, greatly improving production efficiency, and using a horizontal milling machine to replace CNC machine tool machining, thus optimizing the production process and saving fixed asset purchase costs and production costs.

[0004] The above-mentioned hook tail frame processing method is difficult to fix during processing. It requires the sequential use of T-shaped positioning blocks, second pressure plates, positioning pins, first pressure plates, second pads, and first pads to restrict the hook tail frame. The fixing process is cumbersome, inconvenient for users, and affects the processing efficiency of the hook tail frame. Utility Model Content

[0005] The purpose of this utility model is to provide a machining fixture for producing the inner frame of a forged hook tail frame. The second transmission frame slides longitudinally along the extension strip. While sliding longitudinally, the horizontal position of the pressing plate inside the second transmission frame can be adjusted so that the two pressing plates can contact the upper and lower ends of the hook tail frame respectively. The hook tail frame is fixed by the hook tail frame fitting and limiting ring, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a machining fixture for producing the inner frame of a forged hook tail frame, comprising a base, a limiting ring welded to one side of the upper end of the base, a first transmission frame disposed at the middle position of the upper end of the base, a second transmission frame mirror-displayed above the first transmission frame, a pressing plate disposed inside the first and second transmission frames facing the inside of the hook tail frame, a sliding rail disposed at one end of the pressing plate, the pressing plate being embedded inside the sliding rail and slidably connected to the sliding rail, and a first threaded rod longitudinally disposed inside the sliding rail that threadedly engages with the pressing plate.

[0007] Preferably, handles are provided at the upper end of the first threaded rod inside the first transmission frame and the lower end of the first threaded rod inside the second transmission frame, and the handles are welded and fixed to the first threaded rod respectively.

[0008] Preferably, an extension strip is provided in the middle of one end of the second transmission frame, and a support strip is welded to the front end of the extension strip. The extension strip is embedded inside the second transmission frame and slidably connected to the second transmission frame.

[0009] Preferably, a second threaded rod is provided through the extension bar and the second transmission frame, and a nut is provided on one side of the outer side of the second threaded rod, and the inside of the nut is engaged with the external thread of the second threaded rod.

[0010] Preferably, the support bar is welded and fixed to the limiting ring.

[0011] Preferably, the upper end of the first transmission frame and the lower end of the second transmission frame are both recessed with mounting grooves, and the interior of the mounting grooves is connected to the external slot of the pressing plate.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] When the bend of the inner frame of the hook tail frame is fixed and machined by a milling cutter, the side of the hook tail frame is attached to the limiting ring, and the upper and lower contact positions of one end of the hook tail frame respectively contact the first transmission frame and the second transmission frame. When the handles corresponding to the first transmission frame and the second transmission frame are rotated, the rotation of the handles can drive the corresponding external pressing plates to move toward the inner wall of the hook tail frame, directly pushing the upper and lower ends inside the hook tail frame, thereby directly limiting and fixing the hook tail frame. The two handles are close to each other and in close position, which is convenient for the user to use and operate. Furthermore, the pushing from the inside of the hook tail frame to the upper and lower ends, combined with the limitation of the side of the limiting ring, can improve the stability of the hook tail frame during processing.

[0020] The present invention will be further described below with reference to specific embodiments.

[0021] Example 1

[0022] like Figure 1 As shown, a processing fixture for producing the inner frame of a forged hook tail frame in this embodiment includes a base 1. A limiting ring 2 is provided on one side of the upper end of the base 1, and the limiting ring 2 is welded and fixed to the upper end of the base 1. When fixing the hook tail frame, one side of the hook tail frame is attached to the limiting ring 2. A first transmission frame 4 is provided at the middle position of the upper end of the base 1. A second transmission frame 5 is mirrored on the upper end of the first transmission frame 4. One end of the hook tail frame is attached to the first transmission frame 4 and the second transmission frame 5.

[0023] A milling cutter 3 is provided on one side of the front end of the limiting ring 2. When the milling cutter 3 is pushed toward the hook tail frame, it can process the inner frame of the hook tail frame.

[0024] Among them, the first transmission frame 4 and the second transmission frame 5 are provided with a pressing plate 7 facing the inside of the hook tail frame. One end of the pressing plate 7 is provided with a sliding rail 6. The pressing plate 7 is embedded in the sliding rail 6 and slidably connected to the sliding rail 6. The pressing plate 7 slides along the sliding rail 6 and moves toward the hook tail frame, which can clamp and fix the hook tail frame.

[0025] In addition, a first threaded rod 8 is longitudinally arranged inside the sliding rail 6, and the first threaded rod 8 penetrates the part of the pressing plate 7 embedded in the sliding rail 6. The outside of the first threaded rod 8 is threadedly engaged with the pressing plate 7. By rotating the first threaded rod 8 in conjunction with the restriction of the pressing plate 7 by the sliding rail 6, the longitudinal horizontal position can be adjusted. The two pressing plates 7 move longitudinally relative to each other and simultaneously contact the upper and lower ends of the inner wall of the hook tail frame to restrict the hook tail frame.

[0026] To facilitate adjustment of the first threaded rod 8, such as Figure 2 and Figure 3 As shown, handles 12 are provided at the upper end of the first threaded rod 8 inside the first transmission frame 4 and the lower end of the first threaded rod 8 inside the second transmission frame 5. The handles 12 are welded and fixed to the first threaded rod 8 respectively. The first threaded rod 8 can be directly adjusted by rotating the protruding handles 12, and the pressing plate 7 can be adjusted quickly and efficiently.

[0027] To accommodate different sizes of hook-tail frames, such as Figure 4 and Figure 5 As shown, an extension bar 11 is provided in the middle of one end of the second transmission frame 5, and a support bar 10 is provided at the front end of the extension bar 11. The extension bar 11 and the support bar 10 are welded and fixed. The extension bar 11 is embedded in the second transmission frame 5 and is slidably connected to the second transmission frame 5. The second transmission frame 5 can be adjusted by sliding outside the extension bar 11. The adjustment of the horizontal position of the second transmission frame 5 directly adjusts the sliding range of the pressing plate 7.

[0028] A second threaded rod 13 is provided through the extension bar 11 and the second transmission frame 5. A nut 14 is provided on one side of the outer side of the second threaded rod 13, and the inside of the nut 14 is engaged with the external thread of the second threaded rod 13. When the second transmission frame 5 slides outside the extension bar 11 and is adjusted longitudinally, the second threaded rod 13 and the rotation of the nut 14 can directly fix the second transmission frame 5 after the position adjustment.

[0029] To facilitate fixing the support bar 10, such as Figure 1 and Figure 4 As shown, the support bar 10 is welded and fixed to the limiting ring 2. The support bar 10 can be fixed to the outside of the limiting ring 2 to support the second transmission frame 5.

[0030] To facilitate the storage of the pressing plate 7, the upper end of the first transmission frame 4 and the lower end of the second transmission frame 5 are both recessed with mounting grooves 9, and the interior of the mounting grooves 9 is connected to the external slot of the pressing plate 7. When the first transmission frame 4 and the second transmission frame 5 are not in use, the pressing plate 7 will be stored in the mounting grooves 9 and the storage will be completed.

[0031] Working principle: When using the device to fix and process the hook tail frame, when fixing the hook tail frame, one side of the hook tail frame is attached to the limiting ring 2, and one end of the limiting ring 2 is first attached to the first transmission frame 4. According to the size of the hook tail frame, the second transmission frame 5 slides longitudinally within the support bar 10. The second threaded rod 13 passes through the extension bar 11 and fixes the second transmission frame 5 to the outside of the extension bar 11. After rotating the handles 12 corresponding to the second transmission frame 5 and the first transmission frame 4, the rotation of the handles 12 can drive the first threaded rod 8 to rotate respectively. The rotation of the first threaded rod 8 can generate relative movement with the pressing plate 7 inside the first transmission frame 4 and the second transmission frame 5 respectively. The pressing plate 7 is restricted by the sliding rail 6 and can move longitudinally toward the inner wall of the hook tail frame. The longitudinal pushing of the pressing plate 7 is matched with the hook tail frame to attach to the limiting ring 2, restricting and fixing the hook tail frame, driving the milling cutter 3, and the milling cutter 3 processes the inner frame corner of the hook tail frame.
