Description

Technical Field

[0001] This utility model relates to the field of punching equipment technology, and in particular to an automated punching equipment for frame parts. Background Technology

[0002] Traditional frame component punching operations largely rely on manual operation or semi-automated equipment. Workers need to manually place the frame components on the punching equipment, then perform positioning and punching operations. Each hole requires repetitive and tedious actions, which is time-consuming and labor-intensive for mass production, making it difficult to meet the needs of efficient production. Furthermore, the precision of manual operation is difficult to guarantee. Accurate positioning is crucial for ensuring punching quality during frame component processing. However, manual positioning is easily affected by various factors, such as worker skill level and fatigue, leading to deviations in punching position, which in turn affects the assembly and performance of the frame components, increases the defect rate, and causes economic losses for the company. In addition, while traditional semi-automated punching equipment improves production efficiency to some extent, it still has shortcomings in terms of automation and flexibility. For example, some equipment still requires manual intervention in the conveying, positioning, and post-punching collection of frame components, failing to achieve fully automated production. Moreover, these machines are often only suitable for frame components of specific specifications; when encountering frame components of different sizes or shapes, complex adjustments are required, resulting in poor adaptability. Summary of the Invention

[0003] The purpose of this invention is to address the deficiencies of the existing technology by providing an automated punching device for frame components.

A second drive motor is also connected to the lower side of the vertical rotating shaft of the second driving wheel. The second belt is wound between the second driving wheel and the second driven wheel. The plurality of second positioning flange bearings are respectively arranged on the inner side of the second belt on the upper side of the second base plate through vertical positioning shafts with equal spacing.

[0007] The advantages of the above technical solution are: convenient conveying, the conveying and pressing mechanism can prevent the rear end of the frame component from tilting upwards during conveying, and the first belt conveyor and the second belt conveyor can adjust the spacing according to the spacing adjustment mechanism and work together to transport the frame component, so as to facilitate precise processing in subsequent processes.

[0008] A further technical solution of this utility model is: the conveying and pressing mechanism includes a lifting pressure roller and three conveying rollers. The lifting pressure roller is disposed on the upper side of the first belt and the second belt. The conveying rollers are located below the first belt and the second belt and are equidistantly installed on the surface of the first base plate and the second base plate. When the frame component is conveyed backward between the first belt conveyor and the second belt conveyor, the lifting pressure roller and the conveying rollers can jointly press and position the frame component.

[0009] The beneficial effects of the above technical solution are that the frame component can be fixed by the conveying and pressing mechanism so that the frame component can be fed into the marking and processing device in an orderly manner, ensuring the stability and accuracy of the conveying.

[0010] A further technical solution of this utility model is: the spacing adjustment mechanism includes a bidirectional hydraulic cylinder and a connecting piece I.

[0014] A further technical solution of this utility model is as follows: the precision punching mechanism includes an alignment laser pointer, an upper punching die, a lower punching die, a processing hydraulic assembly, a processing mounting frame, and a waste collection box. The lower punching die is installed between the rear end of the front transfer device and the front end of the rear transfer device. A parallel notch is provided in the lateral direction of the lower punching die to limit the lateral movement of the frame component. The processing hydraulic assembly is installed above the lower punching die through an n-shaped processing mounting frame.

When the frame is conveyed to the workpiece collecting platform, the positioning roller and the rubber clamping block clamp the frame together.

[0017] The beneficial effect of the above technical solution is that the distance between the positioning roller and the rubber clamping block can be adjusted by the dual-axis cylinder, so that the positioning roller and the rubber clamping block can clamp the frame part together, which is suitable for production situations where the frame part needs to be fixed.

A first drive motor 135 is also connected to the lower side of the vertical rotating shaft of the first drive wheel 132, and the first drive motor 135 is used to drive the first drive wheel 132 to move. The first belt 134 is wound between the first driving wheel 132 and the first driven wheel 133. A plurality of first positioning flange bearings 15 are respectively arranged on the inner side of the first belt 134 on the upper side of the first base plate 131 through vertical positioning shafts with equal spacing. The bottom end of the vertical positioning shaft is installed in the first base plate 131, and the first positioning flange bearings 15 are installed at the top end of the vertical positioning shaft. The first positioning flange bearings 15 and the first belt 134 are at the same height. The first positioning flange bearings 15 play the role of positioning the first belt 134. In this embodiment, four first positioning flange bearings 15 are provided. Of course, different numbers of first positioning flange bearings 15 can be provided according to the length of the belt.

[0029] like Figure 3As shown, the second belt conveyor 14 includes a second base plate 141, a second drive wheel 142, a second driven wheel 143, multiple second positioning flange bearings 16, and a second belt 144. The second base plate 141 extends in the front-to-back direction and has the same structure as the first base plate 131, and is arranged parallel to one side of the first base plate 131. The second drive wheel 142 and the second driven wheel 143 are respectively mounted on the front and rear ends of the second base plate 141 via vertical shafts. In this embodiment, the second drive wheel 142 is mounted on the rear end of the second base plate 141, and the second driven wheel 143 is mounted on the front end of the second base plate 141. Of course, as a variation of this utility model, the positions of the second drive wheel 142 and the second driven wheel 143 can be interchanged. A second drive motor 145 is also connected to the lower side of the vertical shaft of the second drive wheel 142, and the second drive motor 145 is used to drive the first drive wheel 132 to move. The second belt 144 is wound between the second driving pulley 142 and the second driven pulley 143.

[0030] like Figure 3 As shown, the conveying and pressing mechanism 11 includes a warping pressure roller 111 and three conveying rollers 112. The warping pressure roller 111 is located on the upper side of the first belt 134 and the second belt 144. One end of the warping pressure roller 111 is connected to a swing arm, and a swing arm control device for controlling the deflection of the swing arm is connected to the outside of the swing arm. The swing arm control device is mounted on the frame 6 outside the warping pressure roller 111. The conveying rollers 112 are located below the first belt 134 and the second belt 144 and are equidistantly installed on the surfaces of the first base plate 131 and the second base plate 141. When the frame component 4 is conveyed backward between the first belt conveyor 13 and the second belt conveyor 14, the warping pressure roller 111 and the conveying rollers 112 can jointly press and position the frame component 4. Through the pressing action of the warping pressure roller 111 and the conveying rollers 112, the warping or displacement of the frame component 4 during the conveying process is prevented, ensuring the smoothness and accuracy of the conveying.

[0031] like Figure 3As shown, the spacing adjustment mechanism 12 includes a bidirectional hydraulic cylinder 121 and a connecting member I 122. The bidirectional hydraulic cylinder 121 is installed below the first belt conveyor 13 and the second belt conveyor 14. The hydraulic push rod at the left end of the bidirectional hydraulic cylinder 121 is connected to the first belt conveyor 13 via the connecting member I 122 (specifically, the connecting member I 122 is connected to the outside of the first base plate 131 of the first belt conveyor 13). The hydraulic push rod at the right end of the bidirectional hydraulic cylinder 121 is connected to the second belt conveyor 14 via the connecting member I 122 (specifically, the connecting member I 122 is connected to the outside of the second base plate 141 of the second belt conveyor 14). The hydraulic push rods at both ends of the bidirectional hydraulic cylinder 121 move synchronously. The bidirectional hydraulic cylinder 121 can effectively adjust the spacing between the first belt conveyor 13 and the second belt conveyor 14, making it suitable for a wider range of applications.

Figure 4 As shown, the marking mechanism 21 includes an ink marking head 211, a marking linear module 212, a lifting linear module 213, a transverse linear module 214, and a marking bracket 215. The bottom end of the marking bracket 215 is connected to the frame 6 on one side of the rear end of the front transfer device 1. The inner side of the top end of the marking bracket 215 is connected to the transverse linear module 214. The transverse linear module 214 is then connected to the upper end of the lifting linear module 213. The lower end of the lifting linear module 213 extends downward and connects to the marking linear module 212. The ink marking head 211 is installed at the bottom end of the marking linear module 212. The marking linear module 212 is a module capable of linear movement in the x-axis direction, the lifting linear module 213 is a module capable of linear movement in the y-axis direction, and the transverse linear module 214 is a module capable of linear movement in the z-axis direction. The marking linear module 212, the lifting linear module 213, and the transverse linear module 214 are not existing structures, so a simplified drawing method is used in the figure, and their structures are not described in detail here. The precise marking of the processing position of the frame component 4 can be achieved through the cooperation of three linear modules. The three-axis movement of the ink marking head 211 can be realized by the marking linear module 212, the lifting linear module 213, and the horizontal linear module 214, resulting in good marking effect.

[0033] like Figure 5As shown, the precision punching mechanism 22 includes a positioning laser pointer 221, an upper punching die 222, a lower punching die 223, a processing hydraulic assembly 224, a processing mounting frame 225, and a waste collection box 226. The lower punching die 223 is installed between the rear end of the front transfer device 1 and the front end of the rear transfer device 5. The lower punching die 223 has parallel notches in the lateral direction to limit the lateral movement of the frame component 4. The processing hydraulic assembly 224 is installed above the lower punching die 223 through the n-shaped processing mounting frame 225. The upper punching die 222 is installed at the end of the hydraulic rod 2241 of the hydraulic assembly and corresponds to the position of the lower punching die 223. The waste collection box 226 is located below the lower punching die 223. The positioning laser pointer 221 is installed on the inner side of the front end of the top wall of the processing mounting frame 225.

[0034] like Figure 1-2 and Figure 6 As shown, the rear transfer device 5 is located behind the precision punching mechanism 22. The rear transfer device 5 and the transfer device have the same structure, so the structure of the rear transfer device 5 will not be described here. The workpiece collection table 3 is connected to the rear of the rear transfer device 5. The workpiece collection table 3 includes a positioning roller 31, a dual-axis cylinder 32, and a rubber clamping block 33. The dual-axis cylinder 32 is installed on the inner side of the frame 6 near the bottom. The rubber clamping block 33 is connected to the outer end of the piston rod of the dual-axis cylinder 32 through a connector II 34. The positioning roller 31 is connected to the inner side of the frame 6 through a connector III 35, and the positioning roller 31 and the rubber clamping block 33 are positioned correspondingly. When the frame part 4 is transferred to the workpiece collection table 3, the positioning roller 31 and the rubber clamping block 33 jointly clamp the frame part 4. The distance between the positioning roller 31 and the rubber clamping block 33 can be adjusted by the dual-axis cylinder 32, so that the positioning roller 31 and the rubber clamping block 33 can clamp the frame part 4 together, which is suitable for production situations where the frame part 4 needs to be fixed.

[0035] During operation, the frame component 4 is conveyed backward by the front transfer device 1 to the position of the marking mechanism 21. The ink marking head 211 on the marking mechanism 21 accurately marks the processing position. Then, the alignment laser pen 221 on the precision punching mechanism 22 aligns and calibrates with the marking, and the precision punching mechanism 22 punches holes in the frame component 4. After that, the frame component 4 continues to be conveyed to the next stage, and the rear transfer device 5 conveys the frame component 4 to the workpiece collection table 3 for unloading.
