Description

Technical Field

[0001] The utility model relates to the technical field of electric forklift connecting rod processing, in particular to a double-head punching device for the electric forklift connecting rod. Background Art

[0002] The connecting rod of an electric forklift is a part that connects the fork arm and the frame. It is usually made of metal material and has a certain strength and rigidity. The main function of the connecting rod is to support and fix the fork arm so that it can bear the weight and inertia of the goods during operation and transfer it to the frame. At the same time, it can also keep the relative position and angle between the fork arm and the frame stable. The double-head punching device of the electric forklift connecting rod can be a tool specially designed for punching holes at both ends of the electric forklift connecting rod.

[0003] The punching mechanism in the punching equipment is the core part of the equipment, which is used to realize the double-head punching function. It usually includes a pair of punching heads, which can punch holes at both ends of the connecting rod at the same time. The punching mechanism can be driven by hydraulic, pneumatic or electric means to provide sufficient force and speed for the punching operation.

[0004] Since the original design of the electric forklift connecting rod does not take double-end punching into consideration, the bearing capacity of the connecting rod will be exceeded during the punching process, resulting in insufficient strength and fracture in the middle of the connecting rod. In addition, the punching tool will generate vibration when punching the connecting rod, and the vibration will cause the connecting rod to resonate, thereby increasing the stress in the middle of the connecting rod and making it easy to break, reducing the processing quality of the connecting rod and increasing losses. At the same time, the punching mechanism of the existing punching equipment is usually fixed on a workbench, and the front and rear horizontal positions of the connecting rod are adjusted so that the holes at both ends are punched close to the punching mechanism. However, since the connecting rods of different models of electric forklifts have different sizes, lengths and shapes, the punching equipment is fixed and cannot adapt to connecting rods of different lengths, reducing the versatility and practicality of the punching mechanism.

Those skilled in the art will appreciate that these descriptions are only descriptive and exemplary and should not be construed as limiting the protection scope of the present invention.

[0020] It should be noted that like reference numerals denote similar items in the following drawings, and thus, once an item is defined in one drawing, it may not be further defined or explained in subsequent drawings.

[0021] This embodiment mainly describes a double-head punching device for an electric forklift connecting rod, as follows:

[0022] like Figure 1-3As shown, a double-head punching device for an electric forklift connecting rod comprises a workbench 1, a slide slot 2 is provided at the rear side of the upper end of the workbench 1, an adjustment component 3 is arranged inside the slide slot 2, a support adjustment plate 4 is fixedly installed on both sides of the upper end and left and right sides of the adjustment component 3, a drive motor 5 is fixedly installed at the rear end of the support adjustment plate 4, a drill bit 6 is fixedly installed at the output end of the drive motor 5, a first cylinder 7 is fixedly installed at the front side of the upper end of the workbench 1, a support table 8 is fixedly installed at the output end of the first cylinder 7, and the support table 8 and the workbench are fixedly installed. 1 is arranged in a parallel position relationship, a rod body 9 is placed on the upper end of the support platform 8, the rod body 9 and the drill bit 6 are on the same horizontal plane, a second cylinder 10 is fixedly installed on the left and right sides of the upper end of the support platform 8, a clamping block 11 is fixedly installed on the output ends of the two second cylinders 10, a fixed plate 12 is fixedly installed on the left and right sides of the upper end of the support platform 8, a stabilizing component 13 is arranged in the middle of the upper end of the support platform 8, the stabilizing component 13 includes a pad 131, and a third gas is fixedly installed on the front side of the upper end of the pad 131 Cylinder 132, the output end of the third cylinder 132 is fixedly installed with a stabilizing plate 133, the upper rear side of the pad 131 is fixedly installed with a fixing plate 14, the rod 9 is located in the middle of the opposite surfaces of the stabilizing plate 133 and the fixing plate 14, the rod 9 is placed on the support platform 8, the clamping block 11 is pushed to move by the two second cylinders 10, and the clamping block 11 cooperates with the fixed plate 12 to clamp and fix the rod 9 to ensure the stability of the rod 9 during processing, and the support platform 8 is pushed back by the first cylinder 7 to move an end distance, at this time the drill bit 6 contacts the positions of the two ends of the rod body 9, and as the rod body 9 slowly moves backward, the driving motor 5 drives the drill bit 6 to rotate rapidly, thereby punching holes at both ends of the rod body 9 at the same time; by starting the third cylinder 132, the third cylinder 132 pushes the stabilizing plate 133 to move backward, and cooperates with the fixing plate 14 to contact and clamp the middle position of the rod body 9. By supporting and clamping at the middle position of the connecting rod body 9, the load on the connecting rod body 9 can be evenly dispersed, so that the connecting rod body 9 is more evenly stressed. This can effectively reduce the stress concentration in the middle of the connecting rod and reduce the risk of fracture. During the processing, the punching tool will vibrate when punching the connecting rod body 9, and the vibration will cause the connecting rod body 9 to resonate, thereby increasing the stress in the middle of the connecting rod body 9. By supporting and clamping in the middle position, the vibration and resonance effects of the connecting rod body 9 can be reduced, the stress in the middle of the connecting rod body 9 can be reduced, breakage can be prevented, the processing quality of the connecting rod can be guaranteed, and losses can be reduced; by moving the support adjustment plate 4 to adjust the position of the drive motor 5 and the drill bit 6, the punching mechanism, i.e., the drill bit 6, can be adjusted according to the length of the connecting rod body 9, so that it can adapt to connecting rods of different lengths, thereby improving the versatility and practicality of the punching equipment.

[0023] A storage box 15 is placed on both sides of the upper end of the workbench 1. The storage box 15 is used to connect the metal scraps generated by the punching of the rod body 9.

[0024] A support bar 16 is fixedly installed on both sides of the upper end of the workbench 1, and the support platform 8 is overlapped on the support bar 16. The support bar 16 is provided to support and stabilize the workbench 1.

[0025] Four supporting legs 17 are fixedly mounted on the lower end of the workbench 1 , and the supporting legs 17 provide support for the workbench 1 .

[0026] like Figure 3 As shown, the adjustment component 3 includes a positive and negative threaded rod 31, and a servo motor 32 is fixedly installed on the right end of the positive and negative threaded rod 31. The left and right parts of the outer surface of the positive and negative threaded rod 31 are threadedly connected with an adjustment block 33. The adjustment block 33 and the support adjustment plate 4 are fixedly connected. The servo motor 32 is fixedly connected to the right end of the workbench 1. The positive and negative threaded rod 31 is movably connected to the inside of the slide groove 2. The servo motor 32 drives the positive and negative threaded rod 31 to rotate. Since the left and right ends of the positive and negative threaded rod 31 have threads with different rotation directions respectively, the nuts or adjustment blocks with nuts provided at both ends of the positive and negative threaded rod 31 can move relative to each other. When the adjustment block 33 slides left and right along the positive and negative threaded rod 31, it drives the two support adjustment plates 4 to move left and right, so as to facilitate the adjustment of the position of the support adjustment plate 4.

[0027] When in use, the rod body 9 is placed on the support platform 8, and the two second cylinders 10 push the clamping block 11 to move. The clamping block 11 cooperates with the fixed plate 12 to clamp and fix the rod body 9 to ensure the stability of the rod body 9 during processing. The first cylinder 7 pushes the support platform 8 to move backward a distance. At this time, the drill bit 6 contacts the two end positions of the rod body 9. As the rod body 9 slowly moves backward, the drive motor 5 drives the drill bit 6 to rotate rapidly, so that the two ends of the rod body 9 are punched at the same time, and metal debris falls into the storage box 15 below for storage. By starting the third cylinder 132, the third cylinder 132 pushes the stabilizing plate 133 to move backward, and cooperates with the fixed plate 14 to contact and clamp the middle position of the rod body 9. By supporting and clamping at the middle position of the connecting rod body 9, the load on the connecting rod body 9 can be evenly dispersed, so that the connecting rod body 9 is more evenly stressed. This can effectively reduce the stress concentration in the middle of the connecting rod and reduce the risk of fracture. During the processing, the punching tool will generate vibration when punching the connecting rod body 9, and the vibration will cause the connecting rod body 9 to resonate, thereby increasing the stress in the middle of the connecting rod body 9. By supporting and clamping at the middle position, the vibration and resonance effect of the connecting rod body 9 can be reduced, the stress in the middle of the connecting rod body 9 can be reduced, fracture can be prevented, the processing quality of the connecting rod can be guaranteed, and the loss can be reduced. The servo motor 32 drives the positive and negative threaded rod 31 to rotate. Since the left and right ends of the positive and negative threaded rod 31 have threads with different rotation directions, the nuts or adjustment blocks 33 with nuts provided at both ends of the positive and negative threaded rod 31 can move relative to each other. When the adjustment block 33 slides left and right along the positive and negative threaded rod 31, it drives the two support adjustment plates 4 to move left and right. The position of the drive motor 5 and the drill bit 6 is adjusted by moving the support adjustment plate 4, so that the punching mechanism, that is, the drill bit 6, can be adjusted according to the length of the connecting rod body 9. In this way, it can adapt to connecting rods of different lengths and sizes, thereby improving the versatility and practicality of the punching equipment.
