Description

Technical Field

[0001] This utility model relates to the field of channel steel processing technology, and in particular to a clamping and rotating device for processing H-shaped channel steel. Background Technology

[0002] In the processing of H-beams for forklift masts, a reliable, safe, and fast conveying, clamping, and rotating device is crucial. In existing technology, H-beams are lifted into the processing equipment by personnel using an overhead crane for support and leveling before processing. After one side is processed, the overhead crane is used to flip and rotate the H-beam before processing the other side. This process is inefficient and involves high manual labor intensity.

[0003] Based on the above reasons, considering automatic clamping and rotary machining, the realization of machining different faces of H-shaped channel steel for forklift masts at the same horizontal position has become a new issue in process equipment design. Summary of the Invention

[0004] In view of the above-mentioned defects or deficiencies, the purpose of this utility model is to provide a clamping and rotating device for processing H-shaped channel steel.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A clamping and rotating device for processing H-shaped channel steel includes: a fixed frame, an outer roller mounted on the fixed frame, an inner tilting roller mechanism rotatably mounted on the outer roller, a hydraulic clamp mounted on the inner tilting roller mechanism, and a power mechanism for tilting the inner tilting roller mechanism connected to the inner tilting roller mechanism.

[0007] The inner tilting roller mechanism includes: an inner roller rotatably mounted on an outer roller; sealing end caps are installed on both end faces of the inner roller; a driven wheel is installed between one sealing end cap and the inner roller; and a hydraulic chuck is installed between the other sealing end cap and the inner roller; a hydraulic clamping sliding mechanism is installed on both sealing end caps; rollers are installed on the hydraulic clamping sliding mechanism; and an auxiliary clamping device is installed on one hydraulic clamping sliding mechanism.

[0008] The hydraulic clamping sliding mechanism includes: a platform mounted on a sealing end cover, on which a first slider and a second slider are mounted, the first slider being mounted on the sealing end cover.

[0009] The outer roller has an outer roller oil passage machined on its inner wall, the inner roller has an inner roller oil passage, and the sealing end cap has a sealing end cap oil passage. The outer roller oil passage, the inner roller oil passage, and the sealing end cap oil passage together constitute a built-in hydraulic oil passage, except for the auxiliary clamping device and the hydraulic caliper, which provides power output for the hydraulic clamping sliding mechanism. The auxiliary clamping device and the hydraulic caliper are powered by hydraulic oil pipes connected to the built-in hydraulic oil passage.

[0010] The force mechanism includes: a drive wheel installed at the output end of a servo motor, and the drive wheel and the driven wheel are connected by a belt.

[0011] The hydraulic caliper clamps the hydraulic chuck on the inner tilting roller mechanism, enabling machining of different surfaces at the same horizontal position. Compared with the prior art, the beneficial effects of this utility model are:

[0012] This invention provides a clamping and rotating device for processing H-shaped channel steel. The H-shaped channel steel is transported by rollers, clamped by a hydraulic clamping sliding mechanism, and its inner rotating roller is rotated by a servo motor to achieve multi-position processing. Hydraulic calipers ensure the stability of the inner rotating roller during processing, enabling the transport, clamping, and rotating processing of the H-shaped channel steel to be completed at the same workstation. Furthermore, this invention meets the requirements of simple, quick, and reliable installation and debugging during processing. Attached Figure Description

Detailed Implementation

[0018] The present invention will now be described in detail with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the protection scope of the present invention.

[0019] like Figure 1-4 As shown, this utility model provides a clamping and rotating device for processing H-shaped channel steel, including: a fixed frame 1, an outer roller 4, a servo positioning device 5, a hydraulic caliper 6, and an inner tilting roller mechanism 8. The outer roller 4 is mounted on the fixed frame 1, the inner tilting roller mechanism 8 is rotatably mounted on the outer roller 4, the hydraulic caliper 6 is mounted on the inner tilting roller mechanism 8, and a power mechanism 5 for tilting the inner tilting roller mechanism 8 is connected to the inner tilting roller mechanism 8.

[0020] The fixed frame 1 is equipped with an outer roller 4 for supporting the inner tilting roller mechanism 8. The fixed frame 1 is also equipped with a servo positioning device 5 for pulling the inner tilting roller mechanism 8. The fixed frame 1 is further equipped with a hydraulic caliper 6 for ensuring the stability of the inner tilting roller mechanism 8 during processing.

[0021] Specifically, the inner tilting roller mechanism 8 includes: an inner roller 81 rotatably mounted on the outer roller 4; sealing end caps 82 are installed on both end faces of the inner roller 81; a driven wheel 86 is installed between one sealing end cap 82 and the inner roller 81; and a hydraulic chuck 61 is installed between the other sealing end cap 82 and the inner roller 81; a hydraulic clamping sliding mechanism 84 is installed on both sealing end caps 82; a roller 83 is installed on the hydraulic clamping sliding mechanism 84; and an auxiliary clamping device 85 is installed on one hydraulic clamping sliding mechanism 84. The H-shaped channel steel can be conveyed through the roller 83.

[0022] In this utility model, the hydraulic clamping sliding mechanism 84 includes: a platform mounted on the sealing end cover 82, on which a first slider 841 and a second slider 842 are mounted, and the first slider 841 is mounted on the sealing end cover 82.

[0023] Preferably, the inner wall of the outer roller 4 is machined with an outer roller oil passage 41, the inner roller 81 has an inner roller oil passage 811 arranged inside, and the sealing end cap 82 has a sealing end cap oil passage 821 arranged inside. The outer roller oil passage 41, the inner roller oil passage 811, and the sealing end cap oil passage 821 together constitute a built-in hydraulic oil passage except for the auxiliary clamping device 85 and the hydraulic caliper 6, which provides power output for the hydraulic clamping sliding mechanism 84. The auxiliary clamping device 85 and the hydraulic caliper 6 are connected to hydraulic oil pipes from the built-in hydraulic oil passage to provide power output.

[0024] For example, the servo positioning device 5 is equipped with a drive wheel 51, and the belt 52 is connected to the driven wheel 86 on the inner flipping roller mechanism 8. The flipping of the workpiece is controlled by the belt drive. During processing, the hydraulic caliper 6 clamps the hydraulic chuck 61 on the inner flipping roller mechanism 8 to ensure the stability of the processing and realize the processing of different surfaces at the same horizontal position.

[0025] The working process of this utility model is as follows:

[0026] Initially, roller 83 is in a horizontal position. The H-shaped channel steel enters the inner roller 81 through roller 83. Simultaneously, the H-shaped channel steel is fixed by the hydraulic clamping sliding mechanism 84 and the auxiliary clamping device 85. After the H-shaped channel steel is fixed, the servo positioning device 5 pulls the inner rotating roller mechanism 8 to rotate 90° or 270° via belt drive. After rotating into position, the hydraulic caliper 6 fixes the inner rotating roller mechanism 8. After fixing, the machined surface of the H-shaped channel steel is milled and drilled in a horizontal position. After machining is completed, the hydraulic caliper 6 is released, the servo positioning device 5 pulls the inner rotating roller mechanism 8 back to the initial working state, the hydraulic clamping sliding mechanism 84 and the auxiliary clamping device 85 release the H-shaped channel steel, and the H-shaped channel steel exits the rotary clamping device through roller 83 to the next station.

[0027] This utility model's clamping and rotating device can automatically clamp the workpiece during processing, ensuring that different machining surfaces are processed at the same horizontal position. Simultaneously, it meets the requirements of simple, quick, and reliable installation and debugging during processing.

Therefore, any improvements or modifications that those skilled in the art may make to certain parts of this utility model still embody the principles of this utility model and achieve its purpose, and all fall within the scope of protection of this utility model.
