A clamping device for angle steel

Abstract

This utility model relates to the field of angle steel processing technology, specifically to a clamping device for angle steel, including a frame with rotating components mounted on it. A turntable is fixed between the rotating components, and multiple clamping components are mounted on the turntable. This clamping device uses the clamping components to engage with three sets of downward pressure blocks via protruding posts on a support platform. The protruding posts can be embedded into the grooved structure of the angle steel to form a positioning mechanism. The long downward pressure blocks on both sides and the support blocks correspondingly press the two wings of the angle steel, while the short downward pressure block in the middle provides auxiliary fixation, achieving multi-point, multi-dimensional stable clamping and preventing the angle steel from shifting during processing. The rotating components are directly driven by a drive motor to rotate the shaft, thereby causing the turntable and the clamped angle steel to rotate synchronously. Angle adjustment can be completed without disassembling the angle steel. In conjunction with the auxiliary components, a push cylinder drives a push rod to press against the side of the angle steel, enhancing the stability of long angle steel rotation and processing.

Description

Technical Field

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

[0002] Angle steel is widely used as a common profile in fields such as machining, building construction and steel structure assembly. Its processing often involves multiple steps such as cutting, drilling and welding. In order to ensure processing accuracy and operational safety, angle steel needs to be firmly fixed by clamping devices, and its spatial angle can be flexibly adjusted according to different processing requirements.

[0003] Currently, some angle steel clamping devices on the market can only fix the angle steel in a single position. They cannot adjust the orientation and angle of the angle steel according to changes in the processing procedure. When different sides or inclined parts of the angle steel need to be processed, it is necessary to disassemble, reposition and clamp it multiple times. This is not only cumbersome to operate, but also prone to errors due to repeated positioning, affecting the processing accuracy. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution: a clamping device for angle steel, comprising a frame, on which a rotating assembly is mounted, and a turntable is fixed between the rotating assemblies, with multiple clamping assemblies mounted on the turntable; the rotating assembly includes two sets of bearing seats fixed on the frame, with a rotating shaft connected to the turntable fixed on the inner side of the bearing seats, and a drive motor for driving one side of the rotating shaft to rotate is mounted on the top of the frame; the clamping assembly includes a support platform and a support plate, with a push cylinder hinged to one side of the support plate and a pressure rod hinged to the top of the support plate above the support platform, one end of the pressure rod being hinged to the piston rod of the push cylinder.

[0005] Furthermore, the top of the support platform is fixed with a protruding column and support blocks fixed on both sides of the protruding column.

[0006] Furthermore, three sets of pressing blocks are fixed to the other end of the pressing rod, one of which is shorter than the other two. The protruding post is located at the center of the three sets of pressing blocks, with the two longer sets of pressing blocks opposite to their corresponding support blocks.

[0007] Furthermore, the turntable is equipped with a number of auxiliary components located between the clamping components. The auxiliary components include a vertical plate, a push cylinder is hinged to the side of the vertical plate, and a push rod is hinged to the top of the vertical plate. One end of the push rod is hinged to the piston rod of the push cylinder.

[0008] Furthermore, a turntable is fixed to the outer side of one of the rotating shafts, a side block is fixed to the outer side of the turntable, rubber blocks are installed on both sides of the side block, and a limit platform is fixed on both sides of the turntable on the frame.

[0009] Furthermore, the turntable has multiple slots on its outer side, and a base plate located below the turntable is fixed on the frame. An upper cylinder is installed on the surface of the base plate, and an upper plate is fixed to the piston rod of the upper cylinder. A limiting post that matches the slots is fixed to the top of the upper plate.

[0010] Furthermore, a guide block is fixed on the surface of the base plate, and a pair of guide rods that pass through the guide block are fixed on the top plate, with the limiting post passing through the guide block.

[0011] Compared with the prior art, the technical solution of this application has the following beneficial effects:

[0012] The angle steel clamping device uses a clamping assembly that engages with the protruding post on the support platform and three sets of downward pressure blocks. The protruding post can be embedded into the groove structure of the angle steel to form a positioning. The long downward pressure blocks on both sides and the support block correspondingly press the two wings of the angle steel, while the short downward pressure block in the middle assists in fixing, achieving stable clamping at multiple points and in multiple dimensions, preventing the angle steel from shifting during processing. The rotating assembly is directly driven by a drive motor to rotate the shaft, thereby driving the turntable and the clamped angle steel to rotate synchronously. Angle adjustment can be completed without disassembling the angle steel. In conjunction with the push cylinder of the auxiliary assembly, the push rod is driven to press the side of the angle steel, which can enhance the stability of long angle steel during rotation and processing.

[0018] 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.

[0019] Please see Figure 1-4 The clamping device for angle steel in this embodiment includes a frame 1. Bearing seats 2 are fixed on both sides of the frame 1. A rotating shaft 3 is rotatably connected to the bearing seat 2 through a bearing. A turntable 4 is fixedly connected between the two rotating shafts 3. A drive motor 7 is installed on the right side of the frame 1. The output shaft of the drive motor 7 is connected to the right rotating shaft 3 through a coupling, which can drive the rotating shaft 3 to rotate the turntable 4.

[0020] Among them, such as Figure 3 As shown, two sets of clamping assemblies 5 are installed at intervals along the length of the turntable 4. The clamping assembly 5 includes a bearing platform 55 fixed on the turntable 4 and a support plate 51 distributed opposite to the bearing platform 55. A push cylinder 52 is hinged to the back of the support plate 51, and a pressure rod 53 is hinged to its top. The pressure rod 53 is horizontal and located directly above the bearing platform 55. One end of the pressure rod near the support plate 51 is hinged to the piston rod of the push cylinder 52 through a pin. A protruding post 56 is fixed at the middle of the top of the bearing platform 55, and symmetrical support blocks 57 are fixed on both sides of the protruding post 56. The top surface of the support block 57 The bottom of the lower pressure rod 53, which is attached to the bottom surface of the flange of the angle steel, is fixed with three sets of lower pressure blocks 54 at the bottom of the end away from the support plate 51. There are two sets of lower pressure blocks 54 on the left and one on the right. The length of the lower pressure block 54 on the left is greater than the length of the lower pressure block 54 on the right. The protrusion 56 is located directly below the three sets of lower pressure blocks 54. The two long lower pressure blocks 54 on both sides correspond to the two support blocks 57 on the top and bottom respectively. They are supported by the bearing platform. Their protrusions extend to the inner side of the angle steel for limiting. The support blocks reduce the friction damage of the angle steel. Then, the lower pressure rod is driven to press down by the push cylinder. The lower pressure blocks can limit and press the angle steel, improving the stability of the positioning.

[0021] In addition, such as Figure 4As shown in the diagram, two sets of auxiliary components 6 are installed on the turntable 4 between the two sets of clamping assemblies 5. Each auxiliary component 6 includes a vertical plate 61 fixed to the turntable 4. The vertical plate 61 is horizontally positioned and coaxial with the protruding column 56. A push-up cylinder 63 is hinged to the back of the vertical plate 61, and a push-up rod 62 is hinged to its top. One end of the push-up rod 62 is hinged to the piston rod of the push-up cylinder 63. The push-up rod 62 is located inside the angle steel. When the clamping assembly clamps and fixes the angle steel, the push-up rod, located inside the angle steel, is lifted by the push-up cylinder, thus providing an upward force and improving the clamping stability in conjunction with the clamping assembly.

[0022] like Figure 2 A turntable 8 is fixed to the outer end of the right rotating shaft 3. A side block 9 is fixed to the outer peripheral wall of the turntable 8. Rubber blocks are fixed to both sides of the side block 9. Limiting platforms 10 are fixed on both the left and right sides of the turntable 8 on the frame 1. The movement trajectory of the limiting platform 10 corresponds to that of the side block 9, which can limit the rotation angle of the turntable 8. Four slots are also evenly opened on the outer peripheral wall of the turntable 8. The slots are distributed at intervals along the circumference of the turntable 8. A base plate 11 is fixed on the frame 1 directly below the turntable 8. A guide block 13 and an upper cylinder 12 are fixed on the surface of the base plate 11. The piston rod of the upper cylinder 12 is vertically upward and fixedly connected to the upper plate 15. A limiting post 14 is fixed in the middle of the top surface of the upper plate 15. The top of the limiting post 14 passes through the guide block 13 and is adapted to the slot of the turntable 8. Guide rods 16 are also fixed on both sides of the top surface of the upper plate 15. The guide rods 16 slide through the guide block 13 to ensure the stability of the limiting post 14 when it is raised or lowered.

[0023] The working principle of the above embodiments is as follows:

[0024] Place the single angle steel to be processed on the support platform, so that the channel structure of the angle steel fits over the outside of the convex column. The two flanges of the angle steel rest on the support blocks on both sides. Activate the jacking cylinder, and the piston rod of the jacking cylinder extends, pushing the downward pressure rod to drive the three sets of downward pressure blocks to descend synchronously until the long downward pressure blocks on both sides press against the top surface of the angle steel flanges, and the short downward pressure block in the middle presses against the top surface of the angle steel inside the channel, thus completing the clamping and fixing of the angle steel. Activate the push cylinder, and the piston rod of the push cylinder extends to push the push rod, so that the end of the push rod presses against the side of the angle steel, enhancing the lateral stability of the angle steel. When it is necessary to adjust the processing angle of the angle steel, first activate the upper jacking cylinder, and the piston rod of the upper jacking cylinder retracts, causing the upper jacking plate to descend. This causes the limiting post to disengage from the turntable's bayonet, activating the drive motor. The drive motor drives the rotating shaft, turntable, and turntable to rotate synchronously until the angle steel rotates to the target processing angle. The drive motor is then turned off, and the upper cylinder is activated. The piston rod extends and pushes the limiting post into the corresponding bayonet on the turntable, completing the angle locking. During the turntable's rotation, the side block rotates with the turntable. When the side block contacts the limiting table, the rubber block buffers the impact, limiting the turntable's continued rotation and preventing excessive rotation. After the angle is locked, the angle steel can be cut, drilled, and processed. After processing, each cylinder is turned off in sequence, resetting the lower pressure block and push rod. The processed angle steel is then removed, completing one processing cycle.
