Abstract
Description
Technical Field
[0001] This utility model relates to the field of bogie component fixing technology, specifically a positioning auxiliary device for a CNC bending machine for bogie components. Background Technology
[0002] During the bending process of bogie parts, the auxiliary fixing device ensures accurate positioning of the parts and prevents displacement or deformation during bending, thereby improving bending accuracy and production safety. In use, the parts are placed on the base, the bending position is determined by adjusting the positioning blocks, and then the fastening bolts are tightened to clamp the parts with the clamping arms. The pressure of the clamping arms is transmitted through the mechanical lever principle, ensuring that the parts remain stationary during the bending process.
[0003] Authorization announcement number CN219520112U discloses a fixing mechanism for a bending machine. This device mainly uses a cylinder to easily adjust the spacing of the limit blocks. When the aluminum profile needs to be adjusted to different curvatures, the spacing of the limit blocks can be adjusted simply by pushing and pulling the cylinder. It is simple to operate and convenient to use. By setting a positioning mechanism, aluminum profiles of different diameters can be fixed, which facilitates the bending of the aluminum profile by the hydraulic cylinder. However, the device still has the following defects in actual use:
[0004] The aforementioned patent mainly uses a cylinder for push-pull control, which can adjust the spacing of the limit blocks and fix aluminum profiles of different diameters. However, when the bending machine assists in fixing bogie parts, due to the different shapes of the bending machine parts, the single clamping plate structure is difficult to stabilize the parts during actual fixing. This results in local bulging of the parts during bending, affecting the bending accuracy. Furthermore, it is not easy to calibrate and limit the bending position of the parts during bending, thereby increasing the amount of repeated bending operations and reducing the bending efficiency of the parts.

[0016] 1. Through the structural cooperation of the auxiliary positioning mechanism and the reinforcement mechanism, the spacing of the trapezoidal positioning seats can be adjusted to clamp and fix parts of different sizes. At the same time, during the movement of the positioning seat, the sleeve rod, sleeve and reinforcement block are moved synchronously so that the reinforcement block with reinforcement function can be adjusted synchronously with the spacing of the positioning seat, which increases the auxiliary adjustment effect of the positioning structure. After the positioning seat fixes the part, the lifting and lowering of the slide plate can make the two reinforcement blocks press against the part and fit against the inclined surface of the positioning seat. This not only increases the secondary positioning effect of the part, but also improves the stability of the positioning seat clamping the part and increases the bending accuracy of the bogie parts.
[0017] 2. By adjusting the structure of the limiting component, the square block can easily extend out of the square hole, and the position can be fixed by the meshing structure of the toothed plate and the toothed block, so that the end face of the square block is a limiting structure. Adjust the specified bending point and maintain the position, so that the bending mechanism can be automatically calibrated at the bending point of repeatedly assembled parts of the same model, thereby improving the work efficiency of bending operation.

The two rack plates 25 mesh with the gear 22. The meshing of the rack plate 25 with the gear 22 facilitates the movement of the fixed structure towards each other.
[0026] The reinforcement mechanism 3 includes a slide plate 31, which is connected to the output end of the electric push rod 4. Sliders 32 are symmetrically arranged on the inner side of the slide plate 31, and a reinforcement block 33 is provided at the bottom of the slide block 32. A sleeve 34 is installed on the side of the two reinforcement blocks 33 that are far apart from each other. A sleeve rod 35 is provided on the side of the two positioning seats 26 that are far apart from each other. The two sleeves 34 and the two sleeve rods 35 are adapted to each other. A limiting component 5 is provided inside the two positioning seats 26.
[0027] The inner side of the mounting base 1 is a processing platform, and through slots are staggered on the processing platform. The bottom of the two positioning bases 26 is provided with mounting blocks, and the mounting blocks pass through the through slots and are connected to the sleeve block 24, so as to make the position of the positioning base 26 adjustable to fix parts of different sizes.
[0028] The limiting component 5 includes two sets of square holes 51. The two square holes 51 are opened inside the two positioning seats 26. The two square holes 51 are provided with matching square blocks 52 inside. The two square blocks 52 are provided with grooves 53 on the side away from each other. The inner side of the grooves 53 is evenly arranged with toothed blocks 54. The two positioning seats 26 are fitted with adjusting bolts 57 on the side away from each other. The outer side of the adjusting bolts 57 is provided with matching internal threaded blocks 56.
[0029] A toothed plate 55 is provided on one side of the two internally threaded blocks 56 that are close to each other, and the toothed plate 55 is adapted to the toothed block 54.

[0030] A limiting groove is provided on one side of the two square holes 51, and the limiting groove is matched with the internal thread block 56 for limiting. The two grooves 53 are opposite to the horizontal plane of the limiting groove, which facilitates fixing the position of the square holes.
[0031] Example 1, as Figure 1-3 As shown, the two positioning seats 26 are trapezoidal structures, and the two reinforcing blocks 33 are inverted trapezoidal structures. The inclined surfaces on the outer sides of the two positioning seats 26 are perpendicular to the inclined surfaces on the outer sides of the two reinforcing blocks 33.

At this time, the square block 52 with the specified length can be used as a calibration structure to facilitate the positioning and calibration of the bending part of the same model of part, and facilitate repeated high-precision bending operations.
[0033] Working principle: In the positioning auxiliary device of the CNC bending machine for this bogie component;
[0034] When the bogie components are bent, the components can be placed on the processing table inside the mounting base 1. Then, the servo motor 21 is started to drive the gear 22 to rotate, causing the gear 22 to mesh synchronously with the two sets of rack plates 25. Then, the interlocking rack plates 25 drive the sleeve block 24 to slide on the outside of the mounting rod 23, and the sleeve block 24 drives the positioning seat 26 to move closer to each other, clamping the component to be bent in the center so that the position of the component is fixed. At the same time as the position of the positioning seat 26 moves, the sleeve rod 35, the sleeve 34 and the reinforcing block 33 move synchronously, causing the reinforcing block 33 to drive the slider 32 to move horizontally inside the slide plate 31 so as to synchronously adjust the reinforcing structure of the reinforcing mechanism 3.
[0035] After the bogie components are fixed, the electric push rod 4 drives the slide plate 31 and the slider 32 with synchronous position adjustment to descend vertically with the reinforcing block 33, causing the reinforcing block 33 to contact the positioning seat 26 opposite the vertical plane, so as to calibrate and position the positioning seat 26. At the same time, the bottom surface of the reinforcing block 33 fixes the component, greatly improving the fixing effect of the component and increasing the stability and quality of the component bending.
