Embodiment
[0020] As Figures 1-4 shown, a double - headed punch auxiliary tooling for easy installation includes a punch holder 1 and an auxiliary fastening mechanism. A plurality of punch clamping holes 11 are uniformly arranged along a straight line direction at the top of the punch holder 1. The punch clamping holes 11 penetrate through the bottom of the punch holder 1. The size of the punch clamping holes 11 matches the size of the double - headed punch, and the double - headed punch can just extend into the punch clamping holes 11. At the side of the punch holder 1 corresponding to each punch clamping hole 11, there is a punch fastening hole. The punch fastening hole is perpendicular to and communicates with the corresponding punch clamping hole 11. Each punch fastener 5 of the auxiliary fastening mechanism extends into the punch fastening hole of the punch holder 1, thereby fastening the double - headed punch penetrating into the punch clamping hole 11.
[0021] The side of the punch rod clamping seat 1 is provided with fastening screw holes and fastening guide holes, which are used for auxiliary fastening mechanism installation and adjustment. The auxiliary fastening mechanism is arranged on the side of the punch rod clamping seat 1, and the auxiliary fastening mechanism includes a fastening plate 2, a fastening screw 3 and a fastening guide rod 4. The fastening plate 2 is arranged on the side of the punch rod clamping seat 1, and a fastening guide rod 4 is arranged on the fastening plate 2. Each fastening guide rod 4 is movably inserted into each fastening guide hole on the punch rod clamping seat 1. With the cooperation of the fastening guide rod 4 and the fastening guide hole, the fastening plate 2 can only approach or move away from the punch rod clamping seat 1 along the length direction of the fastening guide rod 4.
[0022] The fastening plate 2 is provided with a screw clearance hole at the position corresponding to the fastening screw hole, and the fastening screw 3 is movably passed through the screw clearance hole. One end of the fastening screw 3 is inserted into the fastening screw hole on the punch rod clamping seat 1 and the fastening screw 3 is threadedly matched with the fastening screw hole. The fastening screw 3 is parallel to the fastening guide rod 4. Limiting parts are provided on both sides of the fastening plate 2 on the fastening screw 3, and the limiting parts cannot pass through the screw clearance hole. Rotating the fastening screw 3 can drive the fastening plate 2 to approach or move away from the punch rod clamping seat 1 along the length direction of the fastening guide rod 4.
[0023] Punch rod fasteners 5 are provided at the positions corresponding to the punch rod fastening holes on the fastening plate 2. The fastening screw 3 is rotated to drive the fastening plate 2 to approach the punch rod clamping seat 1 along the length direction of the fastening guide rod 4, and each punch rod fastener 5 moves into the punch rod fastening hole and finally clamps the punch rods in each punch rod clamping hole 11. The fastening screw 3 is rotated to drive the fastening plate 2 to move away from the punch rod clamping seat 1 along the length direction of the fastening guide rod 4, and each punch rod fastener 5 moves out of the punch rod fastening hole and finally releases the punch rods in each punch rod clamping hole 11.
[0024] In the tooling of this embodiment, the punch fasteners 5 of the auxiliary fastening mechanism can move synchronously. Compared with the tooling of the prior art, there is no need to manually adjust each punch fastener 5 individually, which effectively facilitates the clamping and loosening of the double-headed punch, improves the clamping efficiency of the double-headed punch, and thus improves the processing efficiency of the double-headed punch.
[0025] As a preferred embodiment, a fastening screw hole is provided at the middle position of the side of the punch rod clamping seat 1, and at least one fastening guide hole is provided on both sides of the fastening screw hole on the punch rod clamping seat 1, and at least two fastening guide rods 4 are provided on the fastening plate 2, and each fastening guide rod 4 corresponds to the fastening guide hole respectively.
[0026] See also Figures 2-4, the punch fastener 5 includes a fastening sleeve 51 and a fastening rod 52. An annular clamping groove is provided on the outer end face of the fastening rod 52. The fastening sleeve 51 is sleeved outside the fastening rod 52 and located within the annular clamping groove. The annular clamping groove restricts the axial movement of the fastening sleeve 51 along the fastening rod 52. The fastening sleeve 51 can rotate relative to the fastening rod 52 within the annular clamping groove. When the punch fastener 5 is installed on the fastening plate 2, only the fastening sleeve 51 is connected to the fastening plate 2, and the fastening rod 52 can rotate relative to the fastening plate 2. A fastening notch 53 is provided at the end of the fastening rod 52 facing the punch clamping seat 1. The fastening notch 53 is a U-shaped groove. By rotating the fastening rod 52, the orientation of the fastening notch 53 can be adjusted so that the orientation of the fastening notch 53 can match the orientation of the double-headed punch within the punch clamping hole 11, thereby enabling better clamping and fixing of the double-headed punch.

The adjustment screw 23 is parallel to the adjustment guide hole and the top end of the adjustment screw 23 is rotatably connected to the bottom of the fastening plate 2 through a bearing or other structure. Rotating the adjustment screw 23 can drive the adjustment support member 22 to move along the length direction of the adjustment guide rod 21, thereby adjusting the adjustment support member 22 to a suitable height position.
[0031] When using the tooling of this embodiment to process double-headed punches, adjust each positioning support 22 to a suitable height, insert the double-headed punch into each punch clamping hole 11, and when the bottom end of the double-headed punch is supported on the corresponding positioning support 22, the double-headed punch is at a height suitable for being clamped for processing, and then the auxiliary fastening mechanism clamps each double-headed punch to the punch clamping seat 1 for processing.
[0032] In some embodiments, in order to improve the structural strength of the fastening plate 2, a reinforcement support frame 24 is provided on the end face of the fastening plate 2 away from the punch clamping seat 1. The reinforcement support frame 24 includes a middle support member, an end support member, and a diagonal brace. The middle support member is provided in the middle position of the fastening plate 2. The end support members are provided at both ends of the fastening plate 2. The middle support member and the two end support members are connected by diagonal braces. A plurality of sub-support members are provided between the diagonal brace and the fastening plate 2. Each sub-support member is staggered with the punch fastener 5. The middle support member and the fastening plate 2 of the reinforcement support frame 24 are both between the two limit members.
[0033] In order to further improve the efficiency, there are two punch rod clamping seats 1, and the two punch rod clamping seats 1 are connected by a connecting base plate 12. An auxiliary fastening mechanism is arranged on the end faces of each punch rod clamping seat 1 that are away from each other.
