Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of guardrail drilling, in particular to a punching machine for connecting cross bars of guardrails. Background Art
[0002] During the installation of existing guardrails, cross bars usually need to be drilled at corresponding positions to facilitate connection by fixing means such as bolts. However, traditional drilling methods are usually carried out one by one, that is, first fix a cross bar, then drill multiple holes on it, and finally remove the cross bar and fix the next cross bar in turn. Although this method ensures the stability of the cross bar, it greatly reduces the efficiency of drilling processing and increases the operation time and cost.
[0003] To solve this problem, we propose a punching machine for connecting cross bars of guardrails, which can punch multiple cross bars at one time. This can not only improve the efficiency of punching operations, but also reduce the time and labor costs caused by multiple disassembly and reassembly of cross bars. Content of the Utility Model
[0004] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides a punching machine for connecting cross bars of guardrails to solve the above problems.
[0005] To achieve the above object, a punching machine for connecting cross bars of guardrails of the utility model includes a machine base. Above the surface of the machine base, a drilling machine is installed. On one side of the drilling machine on the surface of the machine base, a sliding seat is horizontally slidably arranged along the length direction. A clamp for fixing the cross bar is installed on the sliding seat. The clamp includes a fixed block, a movable block and a clamping cylinder. The fixed block and the clamping cylinder are respectively fixed on both sides of the surface of the sliding seat. The movable block is located between the fixed block and the clamping cylinder. The movable block close to the clamping cylinder is fixedly connected to the telescopic end of the clamping cylinder. When the telescopic end of the clamping cylinder extends, it can push the movable block to slide towards the fixed block.
[0006] An elastic clamping member for clamping the cross bar is arranged inside the movable block. On the other side of the drilling machine on the surface of the machine base, a cross bar alignment push plate is provided. The cross bar alignment push plate is specifically arranged as follows: the sliding seat fixes the cross bar through the clamp and drives the cross bar to move. When one end of the cross bar contacts the cross bar alignment push plate, relative sliding will occur between the cross bar and the elastic clamping member.
[0007] The utility model has the following advantages compared with the prior art: 1) Through the arrangement of the fixed block, the clamping cylinder and multiple movable blocks, when the clamping cylinder extends, it can push multiple movable blocks to move together and clamp multiple crossbars at the same time, improving the processing efficiency; 2) Through one clamping of the clamping cylinder of the crossbar punching machine for the guardrail connection of the utility model, the length direction of the crossbar can be kept consistent with the length direction of the machine base. Through the arrangement of the crossbar alignment push plate, the quick alignment of the end of the crossbar and the quick adjustment of the punching position can be realized. After adjusting the position of the crossbar, the clamping cylinder can clamp the crossbar quickly for the second time, which is convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] The following further describes in detail the specific embodiments of the utility model with reference to the Figures 1-4 drawings.
[0014] From Figures 1-4Provided is a punching machine for the connecting cross bars of a guardrail, which comprises a machine base 10. Above the surface of the machine base 10, a drilling machine 20 is installed. Along the length direction, a sliding seat 30 is horizontally slidably arranged on one side of the drilling machine 20 on the surface of the machine base 10. A clamp 50 for fixing the cross bar 40 is installed on the sliding seat 30. The clamp 50 includes a fixed block 51, a movable block 52 and a clamping cylinder 53. The fixed block 51 and the clamping cylinder 53 are respectively fixedly installed on both sides of the surface of the sliding seat 30. Among them, the number of movable blocks 52 is at least two, and the movable blocks 52 are located between the fixed block 51 and the clamping cylinder 53. When fixing the cross bar 40, the cross bar 40 can be placed in the gaps between the movable block 52 and the fixed block 51 and between adjacent movable blocks 52. The movable block 52 close to the clamping cylinder 53 is fixedly connected to the telescopic end of the clamping cylinder 53. When the telescopic end of the clamping cylinder 53 extends, it can push the movable block 53 to slide towards the fixed block 51. The sliding direction of the movable block 53 is perpendicular to the sliding direction of the sliding seat 30. When the cross bar 40 is placed between the fixed block 51 and the movable block 52, when the telescopic end of the clamping cylinder 53 extends, it can push all the movable blocks 52 to slide together and clamp the cross bar 40, so as to fix multiple cross bars 40 at one time.
[0015] An elastic clamping member 60 for clamping the cross bar 40 is arranged on the inner side of the movable block 52. On the other side of the drilling machine 20 on the surface of the machine base 10, a cross bar alignment push plate 70 is arranged. The cross bar alignment push plate 70 is specifically arranged as follows: the sliding seat 30 fixes the cross bar 40 through the clamp 50 and drives the cross bar 40 to move. When one end of the cross bar 40 contacts the cross bar alignment push plate 70, relative sliding will occur between the cross bar 40 and the elastic clamping member 60. During work, first place the cross bar 40 on the sliding seat 30, so that the cross bar 40 is stacked in the gaps between the movable block 52 and the fixed block 51 and between adjacent movable blocks 52. Then the clamping cylinder 53 extends a small distance, and the cross bar 40 is pressed tightly through the elastic clamping member 60. After the cross bar 40 is pressed tightly, its length direction will be consistent with the length direction of the machine base 10. Then the sliding seat 30 drives multiple cross bars 40 to move towards the drilling machine 20 together. During the movement, the end of the cross bar 40 will contact the cross bar alignment push plate 70 and thus cannot continue to move. In this way, the end of the cross bar 40 can be quickly aligned and positioned.
[0016] Furthermore, a moving groove is arranged on the surface of the machine base 10. The lower end of the cross bar alignment push plate 70 is slidably arranged in the moving groove. A screw rod 80 is rotatably arranged in the moving groove. The screw rod 80 is threadedly connected to the lower end of the cross bar alignment push plate 70. A hand wheel is fixed at the end of the screw rod 80. By rotating the screw rod 80 through the hand wheel, the cross bar alignment push plate 70 can be driven to slide. The final position of the cross bar 40 is restricted by the cross bar alignment push plate 70. By adjusting the position of the cross bar alignment push plate 70, it is convenient to adjust the fixing position of the cross bar 40, so as to realize punching at different positions on the cross bar 40.
[0017] The following is a specific embodiment of the elastic clamping member 60:
[0018] The elastic clamping member 60 includes a movable plate 61 slidably disposed inside the movable block 52, a first spring 62 connected between the movable plate 61 and the movable block 52, and a clamping guide wheel 63 mounted outside the movable plate 61. The elongation of the clamping cylinder 53 is divided into two steps. The first elongation drives the elastic clamping member 60 to simply clamp the cross bar 40. After the cross bar 40 is positioned by the cross bar alignment push plate 70, the clamping cylinder 53 will undergo a second elongation. During the second elongation, the elastic clamping member 60 will enter the interior of the movable block 52, and the cross bar 40 will be completely clamped by the movable block 52.
[0019] A slider is fixed to the bottom of the movable block 52. A chute is embedded on the surface of the slide base 30. The slider is slidably connected to the chute, and a second spring 521 is connected between the slider and the chute.
[0020] A motor screw rail 90 for driving the movement of the slide base 30 is fixedly provided on the upper surface of the machine base 10.
[0021] A bracket 11 is fixed to the upper surface of the machine base 10. An electric cylinder 100 is connected between the drilling machine 20 and the bracket 11.
[0022] The working principle of a punching machine for connecting cross bars of a guardrail according to the present utility model is as follows:
[0023] During use, first place the cross bar 40 in the gaps between the movable block 52 and the fixed block 51 and between adjacent movable blocks 52. Then, the clamping cylinder 53 performs the first clamping, driving the elastic clamping member 60 to simply clamp the cross bar 40. Then, the slide base 30 drives multiple cross bars 40 to move together in the direction of the drilling machine 20. The ends of the multiple cross bars 40 abut against the cross bar alignment push plate 70 to achieve the alignment position. After the cross bar 40 is positioned by the cross bar alignment push plate 70, the clamping cylinder 53 performs the second clamping. During the second clamping, the elastic clamping member 60 will enter the interior of the movable block 52, and the cross bar 40 will be completely clamped by the movable block 52.
[0024] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
