Description

A metal product processing clamping device Technical Field

[0001] This utility model relates to the field of clamping equipment technology, specifically a clamping device for metal product processing. Background Technology

[0002] In the field of metal processing, clamping devices are core equipment that ensures processing accuracy and operational safety, and are widely used in the manufacturing processes of structural metal components, precision tools, packaging containers, and daily hardware parts. With the increasing demand for industrial automation and precision machining, the scenarios for processing metal products are becoming more complex, and clamping devices often need to operate independently of the worktable, placing higher demands on their flexibility, stability, and adaptability.

[0003] In the existing patent CN222289482U, the position of the rotating plate is adjusted by manually rotating a lever, which has low operating efficiency and poor consistency. In terms of rotation angle, it can only rotate 360 ​​degrees in a plane, cannot be separated from the worktable, and lacks rotation in a vertical plane. Its ability to adapt to multiple angles is limited, making it difficult to deal with complex shaped workpieces. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this utility model provides a metal product processing clamping device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A metal product processing clamping device includes an inverted U-shaped bracket and a rotating ring. The top of the inverted U-shaped bracket is fixedly connected to a fixed frame by welding. A support beam is provided above the fixed frame and is fixedly connected to the shaft of a rotary motor. A lifting seat is provided above the rotary motor for fixing the clamping device to the lifting bracket. Threaded holes around the base of the rotary motor are connected and fixed to the lifting seat by screws. Bearing seat grooves are provided on both sides of the inner wall below the inverted U-shaped bracket. A first clamping rotating component and a second clamping rotating component are respectively provided on the bearing seat grooves on both sides. The first clamping rotating component and the second clamping rotating component pass through square through holes on both sides of the rotating ring and are fixedly connected to the rotating ring.

[0007] The first clamping rotating assembly is the same as the second clamping rotating assembly and operates simultaneously. The rotating ring rotates manually. The first clamping rotating assembly includes a pressure plate, a cylinder, a conversion component, and a bearing seat. The rear side of the pressure plate is fixedly connected to the telescopic rod on the cylinder. The cylinder passes through a square through hole on one side of the rotating ring and is fixed by an outer fixing component of the ring. The cylinder base is fixedly connected to the conversion component. The circular rotating shaft on the rear side of the conversion component is rotatably connected to the bearing in the bearing seat. The bearing seat is fixed in the bearing seat groove. An independent lifting platform is provided below the rotating ring. The lifting platform is used to lift metal products.

[0008] Preferably, screw one and screw two are respectively provided on the left and right sides of the outer ring fixing member.

[0009] Preferably, the conversion component has a base groove on one side and a circular rotating shaft on the other side. The rotating surface of the circular rotating shaft has multiple circular through holes, which are embedded and fixed to the telescopic screw on the bearing in the bearing seat.

[0010] Compared with the prior art, the present invention provides a metal product processing clamping device, which has the following beneficial effects:

[0011] By employing a composite structure design of an inverted U-shaped bracket and a rotating ring, traditional planar rotation is extended to 360° omnidirectional rotation in the vertical plane. A rotary motor drives the support beam to achieve axial rotation of the foundation. Simultaneously, manual adjustment of the rotating ring can cause the first and second clamping rotating components, symmetrically arranged on both sides, to deflect vertically around the bearing seat. This dual-degree-of-freedom rotation mechanism allows the workpiece to complete spatial posture adjustment without relying on a fixed worktable. It is particularly suitable for multi-angle processing requirements of irregularly shaped metal parts, such as curved containers and asymmetrical hardware parts, solving the core defects of the single rotation dimension and poor adaptability in the CN222289482U patent.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] This embodiment of a metal product processing clamping device, as shown in Figures 1-3, includes an inverted U-shaped bracket 4. The top of the inverted U-shaped bracket 4 is rigidly connected to a fixed frame 2 by welding. A support beam 14 is vertically arranged above the fixed frame 2. The support beam 14 is fixedly connected to the rotating shaft of a rotary motor 3 by a flange, forming an axial rotation base structure. The top of the rotary motor 3 is connected to a lifting base 15 by a screw. The surface of the lifting base 15 is provided with a standard industrial lifting interface for suspending the entire device on a workshop lifting bracket.

[0018] The inverted U-shaped bracket 4 has symmetrical bearing seat grooves 12 machined on both inner walls. The first clamping rotating assembly 5 and the second clamping rotating assembly are respectively installed in the two sets of bearing seat grooves 12. The two sets of clamping assemblies have the same structure and work synchronously. They pass through the square through holes 13 on both sides of the rotating ring 1 and form a rigid connection with the rotating ring 1. The outer edge of the rotating ring 1 is machined with anti-slip texture to facilitate manual rotation and adjustment by the operator.

[0019] The first clamping and rotating assembly 5 includes a pressure plate 6, a cylinder 8, a conversion component 10, and a bearing seat 11. The pressure plate 6 is made of high-carbon steel, and its rear end is fixedly connected to the telescopic rod of the cylinder 8 by bolts. After the cylinder 8 passes through the square through hole 13 of the rotating ring 1, it is radially limited and fixed by the outer fixing component 9 of the ring. The conversion component 10 adopts a split design. Its front end is fixed to the base of the cylinder 8 by a base groove 101, and its rear end forms a rotating pair with the bearing in the bearing seat 11 by a circular rotating shaft 102 with a circular through hole.

[0020] An independent lifting platform 7 is located directly below the rotating ring 1. The lifting platform 7 is hydraulically driven and has a replaceable workpiece positioning module on its surface.

[0021] In some examples, the lifting platform 7 can be precisely controlled by a PLC controller to meet the positioning requirements of metal products of different sizes. The bottom of the lifting platform 7 is integrated with a laser positioning module, which projects a cross-shaped positioning laser beam during operation to help operators quickly align the metal product processing reference surface.

[0022] In some examples, screw 902 and screw 903 are respectively provided on both sides of the fixing member 9. The fixing stability of the cylinder 8 is enhanced by the double screw diagonal locking method, which prevents the component from shifting due to high frequency vibration.

[0023] In some examples, the surface of the circular shaft 102 of the conversion element 10 is evenly distributed with 12 sets of circular through holes with a diameter of 6mm, which together with the telescopic lead screw in the bearing seat 11 form a multi-point positioning structure, enabling precise angle locking.

[0024] In some examples, the contact surface of the pressure plate 6 is coated with a rubber layer with a high coefficient of friction, and the surface of the rubber layer is processed with staggered anti-slip grooves, which can improve the friction of clamping metal products.

[0025] In some examples, a shock-absorbing washer assembly is provided at the connection between the hoisting base 15 and the rotary motor 3. The assembly uses a composite structure of rubber and stainless steel wave springs, which can effectively absorb high-frequency vibrations during equipment operation.

[0026] In some examples, the inner wall of the inverted U-shaped bracket 4 is provided with a hollow guide groove and is made of aluminum alloy material, which enables lightweight adjustment that can be operated with one hand.

[0027] The working principle of this utility model is as follows:

[0028] The operator first suspends the entire device on the workshop hoisting bracket using the standard industrial interface of the hoisting base 15, ensuring that the hoisting base 15 and the rotary motor 3 are securely connected by screws. The fixed frame 2 at the top of the inverted U-shaped bracket 4 and the supporting beam 14 form a rigid support structure. The rotating shaft of the rotary motor 3 is fixed to the supporting beam 14 through a flange, providing a power base for horizontal rotation.

[0029] When the rotary motor 3 is started, its shaft drives the support beam 14 to rotate horizontally around the vertical axis, causing the inverted U-shaped bracket 4 and the clamping assembly to rotate as a whole. This axial rotation allows the metal product to be adjusted at the processing angle on the horizontal plane, meeting the orientation requirements of processes such as drilling and milling.

[0030] The operator manually rotates the rotating ring 1, which synchronously drives the first clamping rotating assembly 5 and the second clamping rotating assembly to deflect around the axis of the bearing seat 11 through the square through holes 13 on both sides. Since the circular rotating shaft 102 of the conversion component 10 forms a rotating pair with the bearing in the bearing seat 11, and the multiple sets of circular through holes on the circular rotating shaft 102 are embedded and fixed with the telescopic screw in the bearing seat, the pressure plate 6 of the clamping assembly can be adjusted 360° in the vertical plane along with the rotating ring 1.

[0031] Metal products are placed on the lifting platform 7. After the lifting platform 7 is adjusted to the target height by hydraulic drive, the cylinder 8 pushes the pressing plate 6 forward, using its high-friction rubber layer to press the workpiece. During the processing, if it is necessary to adjust the spatial posture of the workpiece, the horizontal rotation of the rotary motor 3 and the vertical deflection of the manual rotating ring 1 can be linked together, and the vertical lifting of the lifting platform 7 can be combined to form omnidirectional positioning in three-dimensional space, without disassembling the workpiece or relying on a fixed worktable.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
