Detailed Embodiments

[0016] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] Please refer to Figures 1-3, the present utility model provides a technical solution: a clamping device for a numerically controlled steel plate sawing and milling machine tool, including a workbench 1, on which a first slide rail 2, a steel plate cushion table 3 and a second slide rail 4 are successively arranged from front to back. The first slide rail 2 and the second slide rail 4 are arranged in parallel; the number of steel plate cushion tables 3 is 2, which are respectively adjacent to the first slide rail 2 and the second slide rail 4. Moving plates 5 are slidably arranged on the left and right sides of the first slide rail 2 and the second slide rail 4 respectively. Sliders are arranged under the moving plates 5 and are slidably connected to the corresponding first slide rail 2 or second slide rail 4 through the sliders; parallel clamping plates 6 are arranged on both sides of the moving plates 5, and the height of the steel plate cushion table 3 is higher than the height of the lower end surface of the parallel clamping plates 6; a saw slot 7 is arranged in the middle of the parallel clamping plates 6, and the positions of the two saw slots 7 correspond to each other. The parallel clamping plates 6 are driven by a hydraulic cylinder 8.

[0018] Specifically, a hydraulic cylinder 8 is arranged on the workbench 1. The driving end of the hydraulic cylinder 8 is hinged with a connecting arm 9. A rotating rod 10 is arranged in the middle of the connecting arm 9. The lower end of the rotating rod 10 is arranged on the upper side of the workbench 1. One end of the connecting arm 9 is hinged with a first connecting rod 11, and the other end is hinged with a second connecting rod 12. The first connecting rod 11 and the second connecting rod 12 are respectively connected to the moving plates 5 on both sides.

[0019] Specifically, both the first connecting rod 11 and the second connecting rod 12 are composed of a spherical plain bearing and a hexagonal pillar. The number of spherical plain bearings is 2, which are respectively arranged at both ends of the hexagonal pillar. The two spherical plain bearings are respectively connected to the moving plate 5 and the connecting arm 9. The spherical plain bearing 2 is a spherical sliding bearing, and its sliding contact surface is an inner spherical surface and an outer spherical surface. It can rotate and swing at any angle during movement. It is made by using a variety of special process treatment methods such as surface phosphating, chipping, padding, and spraying. The spherical plain bearing has the characteristics of large load capacity, impact resistance, corrosion resistance, wear resistance, self-aligning, good lubrication, etc. The spherical plain bearing can bear a large load. According to its different types and structures, it can bear radial load, axial load or combined load of radial and axial loads existing simultaneously. Since a composite material is inlaid on the outer spherical surface of the inner ring, the bearing can generate self-lubrication during operation. It is generally used for swing movements at low speeds and low-speed rotations, and can also make inclined movements within a certain angle range. When the concentricity between the supporting shaft and the shaft housing hole is relatively large, it can still work normally.

[0020] Specifically, the parallel clamping plate 6 is composed of a first clamping plate 6-1 and a second clamping plate 6-2. The first clamping plate 6-1 and the second clamping plate 6-2 are parallel to each other and are respectively adjacent to the two end heads on both sides of the moving plate 5. There is enough distance between the first clamping plate 6-1 and the second clamping plate 6-2 to ensure sufficient stability when clamping the steel plate.

[0021] Specifically, the inner ends of the first clamping plate 6-1 and the second clamping plate 6-2 are provided with abrasive plates 13. The provided abrasive plates 13 increase the friction between the first clamping plate 6-1 and the second clamping plate 6-2 and the steel plate, avoiding sliding displacement of the steel plate during cutting.

[0022] Working principle: When the utility model is working, the provided steel plate pad 3 can pre-place the steel plate. The parallel clamping plates 6 on the moving plate 5 can quickly clamp the steel plate. When the hydraulic cylinder 8 is started, it drives the connecting arm 9 to rotate. The rotating connecting arm 9 drives the first connecting rod 11 and the second connecting rod 12 to move, indirectly driving the moving plates 5 on both sides to move in adjacent or opposite directions. When the moving plates 5 on both sides move in the adjacent direction, the first clamping plates 6-1 and the second clamping plates 6-2 provided on both sides quickly position and clamp the steel plate. The provided saw slot 7 facilitates the cutting of the steel plate.

[0023] In the description of the present invention, unless otherwise clearly specified and limited, the terms "installation", "connection", "connection", and "fixation" shall be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or integrated; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0024] The standard parts used in the present invention can all be purchased from the market. The special-shaped parts can be customized according to the description of the specification and the drawings. The specific connection methods of each part all adopt conventional means such as bolts, rivets, and welding that are mature in the prior art.
