Description

Technical Field

[0001] This utility model relates to the technical field of milling and welding integrated machines, and in particular to a clamping unit for milling and welding integrated machines. Background Technology

[0002] Existing milling, splicing, and welding integrated machines are a type of integrated equipment used to form large-sized steel plates by first milling, then splicing, and finally welding smaller steel plates. This equipment typically includes a fixed end, a moving end, a pusher mechanism, and a roller table. Both the fixed and moving ends include a frame and multiple clamping units installed within the frame. These clamping units are used to firmly hold the steel plates to complete the milling, splicing, and welding processes.

[0003] However, existing clamping units include an upper lifting device and a lower pressing device, but both the upper lifting device and the lower pressing device are controlled by hydraulic cylinders. This structure is fine for splicing small steel plates of the same thickness into large steel plates, but once it is necessary to splice small steel plates of different thicknesses into large steel plates, the existing clamping units are no longer suitable for production needs. Utility Model Content

[0004] In order to solve the above-mentioned problems of the prior art, the present invention provides a clamping unit for a milling and welding integrated machine that can be used to produce a large steel plate made of small steel plates of different thicknesses.

[0005] To achieve the above objectives, this utility model provides a clamping unit for a milling and welding integrated machine, which is suitable for multiple units to be installed side-by-side within the frame of the milling and welding integrated machine. The clamping unit includes:

[0006] The upper lifting device includes an upper lifting plate, an upper lifting electric cylinder and a pair of upper lifting guide plates. The upper lifting electric cylinder is mounted on the frame and its piston is fixedly connected to the upper lifting plate. The pair of upper lifting guide plates are symmetrically fixed on the upper lifting plate and slidably connected to the frame.

[0007] The pressing device includes a pressing plate, a pressing cylinder and a pair of pressing guide plates. One end of the pressing cylinder is connected to the frame and the other end is connected to the pressing plate. The pair of pressing guide plates are symmetrically fixed on the pressing plate and slidably connected to the frame.

[0008] By incorporating an upper electric cylinder in the upper lifting device, the upper lifting action can be precisely determined through numerical control if the steel plates being spliced ​​have different thicknesses. This allows the milling, splicing, and welding integrated machine to simultaneously clamp steel plates of different thicknesses for milling, splicing, and welding. The aforementioned structure of a pair of guide plates in both the upper and lower pressing devices ensures smoother vertical movement of the upper and lower plates, resulting in more stable clamping of the steel plates by the clamping unit.

[0009] Furthermore, the lifting device includes a pair of lifting electric cylinders, which are symmetrically located on both sides of the pair of lifting guide plates and arranged in a cross shape with the pair of lifting guide plates.

[0010] The above structural arrangement makes the upper jacking device more stable, and the upward force of the upper jacking plate more balanced and stable.

[0011] Furthermore, a central slot is provided on the upper top plate, and the upper lifting device also includes an upper lifting cylinder. The upper lifting cylinder is fixedly installed at the central slot of the upper top plate at its top. The piston of the upper lifting cylinder is equipped with an upwardly protruding guide column universal ball at its top end, which is configured to be able to move between the upward lifting position and the downward retracted position through the central slot. In the upward lifting position of the piston of the upper lifting cylinder, the guide column universal ball is higher than the upper surface of the upper top plate; in the downward retracted position of the piston of the upper lifting cylinder, the guide column universal ball is lower than or flush with the upper surface of the upper top plate.

[0012] With the above structural design, the upper hydraulic cylinder is installed at the center of the upper plate, with a pair of upper electric cylinders and a pair of upper guide plates, making the structure very stable. At the same time, driven by the piston of the upper hydraulic cylinder, the universal ball of the guide column can protrude from the upper surface of the upper plate when needed (i.e. when the steel plate moves), thereby avoiding wear on the upper plate during the movement of the steel plate.

[0013] Furthermore, the guide post universal ball includes a bullseye bearing mounted on the top of the piston of the upper cylinder and a rolling steel ball mounted in the center of the bullseye bearing. When the piston of the upper cylinder moves between its upward lifting position and its downward retracting position, the rolling steel ball is higher or lower than the upper surface of the upper plate.

[0014] Furthermore, the upper top plate has symmetrical mounting slots on both sides of its central slot, and the piston of the upper electric cylinder has a stud installed at its top. The stud passes through the mounting slot and is fixedly connected to the upper top plate by a nut.

[0015] The above structural design ensures that the piston of the upper electric cylinder is fixedly connected to the upper plate, thereby stably driving the upper plate to move.

[0016] Furthermore, the upper guide plate is an inverted L-shape with an upper horizontal part and a lower vertical part. The upper horizontal part is fixedly connected to the upper top plate, and the lower vertical part is equipped with a slider, which is slidably connected to the slide rail on the frame.

[0017] Furthermore, the lower pressure guide plate is L-shaped and has a lower horizontal part and an upper vertical part. The lower horizontal part is fixedly connected to the lower pressure plate, and the upper vertical part is equipped with a slider, which is slidably connected to the slide rail provided on the frame.

[0018] The above structural design allows the upper guide plate and the lower pressure guide plate to be stably connected to the upper plate and the lower pressure plate, respectively, while also being slidably connected relative to the frame.

[0019] Furthermore, one end of the pressure cylinder is pivotally connected to the frame, and the other end is pivotally connected to the pressure plate.

[0020] These and other aspects of the present invention will be more clearly illustrated by referring to the embodiments described below. Attached Figure Description

[0032] The specific embodiments of this utility model will now be described in conjunction with the accompanying drawings.

[0033] like Figures 1 to 3 This invention illustrates a clamping unit 100 for a milling and welding integrated machine according to a specific embodiment of the present invention, which is suitable for multiple units to be installed side-by-side, such as... Figure 4 and Figure 5 The milling and welding integrated machine 1000 shown is housed within the frame 302 of its fixed end 200 and movable end 300. It should be understood that, as... Figure 4 The milling and welding integrated machine 1000 shown has multiple clamping units 100 arranged horizontally inside the frame 302.

[0034] like Figures 1 to 10 As shown, each clamping unit 100 includes an upper lifting device 2 and a lower pressing device 4. The upper lifting device 2 includes an upper lifting plate 21, a pair of upper lifting electric cylinders 23, and a pair of upper lifting guide plates 25. The pair of upper lifting guide plates 25 are symmetrically fixed to the upper lifting plate 21 and slidably connected to the side wall 332 of the frame 302 (see Figure 1). Figure 5 The pair of upper electric cylinders 23 are symmetrically located on both sides of the pair of upper guide plates 25 and are mounted on the frame 302 at their bottom, so that the pair of upper electric cylinders 23 and the pair of upper guide plates 25 are arranged in a cross shape, and the piston 230 of the upper electric cylinder 23 is fixedly connected to the upper plate; the lower pressing device 4 includes a lower pressing plate 41, a lower pressing cylinder 43 and a pair of lower pressing guide plates 45. One end of the lower pressing cylinder 43 is pivotally connected to the frame 302 and the other end is pivotally connected to the lower pressing plate 41. The pair of lower pressing guide plates 45 are symmetrically fixed on the lower pressing plate 41 and slidably connected to the frame 302.

[0035] like Figures 6 to 10 As shown, in this embodiment, a central slot 210 is provided on the upper top plate 21. Additionally, the upper lifting device 2 includes an upper lifting cylinder 27. The upper lifting cylinder 27 is fixedly installed at the central slot 210 of the upper top plate 21 via a fixing bolt 271 at its top 273. Furthermore, the piston 270 of the upper lifting cylinder 27 has an upwardly protruding guide post universal ball 272 mounted at its top end. The piston 270 is configured to penetrate the central slot 210 in the upward lifting position (see...). Figure 8 The height of the lift is H1) and the downward retraction position (see Figure 7 Activities between ) . Among them, such as Figure 8 As shown, when the piston 270 of the upper cylinder 27 is in the upward lifting position, the guide column universal ball 272 is higher than the upper surface of the upper plate 21. Thus, the guide column universal ball 272 can lift the moving workpiece 22 (specifically a steel plate in this embodiment), thereby preventing wear on the upper plate 21 during the movement of the workpiece 22. Figure 7 As shown, when the piston 270 of the upper cylinder 27 is in the downward retracted position, the guide column universal ball 272 is lower than or flush with the upper surface of the upper plate 21.

[0036] like Figure 9 As shown, in this embodiment, the upper top plate 21 has symmetrical mounting slots 212 on both sides of its central slot 210. The piston 230 of the upper top electric cylinder 23 has a stud 232 mounted on its top end. The stud 232 passes through the mounting slot 212 and is fixedly connected to the upper top plate 21 by a nut (not shown).

[0037] like Figure 9 and Figure 10 As shown, in this embodiment, the guide post universal ball 272 includes a bullseye bearing 2721 mounted on the top of the piston 270 of the upper cylinder 27 and a rollable steel ball 2723 mounted in the center of the bullseye bearing. When the piston 270 of the upper cylinder 27 moves between its upward lifting position and downward retraction position, the rollable steel ball 2723 is higher or lower than the upper surface of the upper plate 21 to cope with the moving and non-moving states of the workpiece 22.

[0038] For example Figure 1 , Figure 3 and Figure 10 As shown, in this embodiment, the upper guide plate 25 is an inverted L-shape with an upper horizontal part 251 and a lower vertical part 253. The upper horizontal part 251 is fixedly connected to the upper top plate 25, and the lower vertical part 253 is equipped with a slider 26, which is slidably connected to the slide rail 312 provided on the frame 302.

[0039] For example Figure 1 and Figure 3 As shown, in this embodiment, the lower pressure guide plate 45 is L-shaped and has a lower horizontal part 451 and an upper vertical part 453. The lower horizontal part 451 is fixedly connected to the lower pressure plate 41, and the upper vertical part 453 is equipped with a slider 46, which is slidably connected to the slide rail 312 provided on the frame 302.

[0040] In this embodiment, when the workpiece 22 enters the frame 302 of the fixed end 200 of the milling and welding integrated machine 1000, the control system (not shown) of the entire milling and welding integrated machine 1000 first detects the thickness of different parts of the workpiece 22 within the range of multiple horizontally arranged clamping units 100, and then starts the clamping unit 100 accordingly. The upper lifting device 2 of each clamping unit 100 determines the upward movement distance of the piston 230 of its upper lifting cylinder 23 according to the thickness of the workpiece 22 within its clamping range, thereby splicing plates of different thicknesses while keeping the upper surface of the workpiece 22 flat.
