[0021] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.
[0022] The tooling for punching holes in thin-walled tube parts, such as Figure 1 and Figure 2 As shown, it includes a base 1 and a support column 2 fixedly connected to the base 1 by welding, a fixed semi-cylinder 3 which is horizontally arranged and has an arc surface located directly below the support column 2 is fixedly connected by welding to the side wall of the support column 2, a sliding semi-cylinder 4 with a radius consistent with the fixed semi-cylinder 3 is detachably connected to the support column 2 and the fixed semi-cylinder 3, and a thin-walled tube part is sleeved on the fixed semi-cylinder 3 and the sliding semi-cylinder 4, so that the fixed semi-cylinder 3 and the sliding semi-cylinder 4 can achieve stable support and limit the inner wall of the thin-walled tube part, thereby reducing the extrusion deformation of the thin-walled tube part during the punching process, thereby affecting the punching quality and punching accuracy, the arc surface of the sliding semi-cylinder 4 is located directly above it and a long groove 5 for making way is opened on its arc surface, and the long groove 5 for making way is set It is used to achieve stable yielding during the punching process of thin-walled tube parts, ensuring that drill bits and other tools can stably perform punching processing on thin-walled tube parts. At the same time, the sliding semi-cylinder 4 is set to a detachable connection structure. The widths of the long grooves on different sliding semi-cylinders 4 are different, so that users can choose and replace suitable sliding semi-cylinders 4 according to their usage requirements, thereby ensuring that the overall adaptability of the structure is better. A locking portion that can be abutted against the bottom surface of the fixed semi-cylinder 3 is provided on the base 1 below the fixed semi-cylinder 3. With the help of the provided locking portion, a pressing force can be applied to the thin-walled tube parts, so that the thin-walled tube parts can be stably pressed and limited, ensuring that the thin-walled tube parts can be kept in a stable position during processing, thereby ensuring that the quality of the thin-walled tube parts being punched is better.
[0023] like Figure 1 and Figure 2As shown, the locking portion includes a plurality of vertically arranged support blocks 6, and the plurality of support blocks 6 are distributed in an array along the length direction of the fixed semi-cylinder 3. A locking screw 7 which is vertically arranged and can be tightened against the bottom surface of the fixed semi-cylinder 3 is threadedly connected to the support block 6. An adjusting block 8 is integrally formed and fixedly connected to the top of the locking screw 7. A plurality of circumferentially distributed force rods 9 are fixedly connected to the side wall of the adjusting block 8. The user can choose the number of locking screws 7 to be used according to needs, so that the overall adaptability of the structure is better. The setting of the force rod 9 allows the user to better apply a force to the locking bolt, so that the locking screw 7 can rotate relative to the support block 6, and then with the help of the threaded connection between the locking screw 7 and the support block 6, the locking screw 7 can slide up and down vertically, thereby driving the adjusting block 8 to tighten and loosen the thin-walled tube parts.
[0024] like Figure 1 and Figure 2 As shown, an elastic arc-shaped piece 10 is fixedly connected to the top surface of the adjusting block 8 by welding, and the concave surface of the elastic arc-shaped piece 10 faces the fixed semi-cylinder 3. A plurality of weakening grooves 11 distributed circumferentially are provided on the elastic arc-shaped piece 10, and the weakening groove 11 on the side away from the center line of the elastic arc-shaped piece 10 is arranged through. The weakening groove 11 is used to weaken the structural strength of the elastic arc-shaped piece 10, so that the elastic arc-shaped piece 10 can be better elastically deformed when it contacts with the thin-walled tube parts. Driven by the adjusting block 8, the elastic arc-shaped piece 10 will resist the thin-walled tube parts and gradually squeeze the elastic arc-shaped piece 10 to deform, so as to achieve buffering of the contact process between the adjusting block 8 and the thin-walled tube parts, and at the same time increase the contact area of the locking part as a whole and the thin-walled tube parts, so that the distribution of the force applied by the locking part to the thin-walled tube parts is more uniform, and the degree of extrusion and deformation of the thin-walled tube parts by the locking part is reduced, so that the thin-walled tube parts can be better punched.
[0025] like Figure 1 and Figure 2 As shown, a plurality of limiting screw holes 12 are provided just below the arc surface of the fixed semi-cylinder 3, and one of the limiting screw holes 12 is internally threadedly connected to a limiting inner hexagonal bolt 13. The plurality of limiting screw holes 12 are provided so that the user can adjust the inner hexagonal bolt 13 according to the length of the thin-walled tube parts and install it in a suitable limiting hole, so that the overall applicability of the structure is better. When the thin-walled tube parts are installed, the initial limiting of the thin-walled tube parts is achieved by abutting against the side wall of the screw head of the inner hexagonal bolt 13, thereby making the installation process and installation effect of the thin-walled tube parts better.
[0026] like Figure 1-Figure 4As shown, a T-shaped mounting groove 14 is provided on the support column 2 and the fixed semi-cylinder 3, and the T-shaped mounting groove 14 on the side away from the fixed semi-cylinder 3 is horizontally penetrated, and a T-shaped mounting block 15 that is interlocked with the T-shaped mounting groove 14 is fixedly connected to the sliding semi-cylinder 4 by welding. When the T-shaped mounting block 15 and the T-shaped mounting groove 14 are interlocked with each other, the end surface of the fixed semi-cylinder 3 on the side away from the support column 2 is flush with the end surface of the sliding semi-cylinder 4, and the plug-in connection between the T-shaped mounting block 15 and the T-shaped mounting groove 14 has a good structural stability to strengthen the connection stability between the sliding semi-cylinder 4 and the support column 2 and the fixed semi-cylinder 3 A through hole is vertically penetrated on the upper edge of the sliding semi-cylinder 4, and a tightening screw 16 is arranged in the through hole and is threadedly connected to the support column 2. The preliminary connection between the sliding semi-cylinder 4 and the support column 2 and the fixed semi-cylinder 3 is achieved by the joint action of the T-shaped mounting block 15 and the T-shaped mounting groove 14, and the sliding semi-cylinder 4 is further limited by the limiting of the locking bolt to ensure that the sliding semi-cylinder 4 can be kept in a stable position when drilling, and to ensure that the supporting and limiting functions of the sliding semi-cylinder 4 are more stable. The tightening screw 16 is threadedly connected to the support column 2, and the sliding semi-cylinder 4 is stably limited by the tightening screw 16.
