Description

Technical Field

[0001] This utility model relates to the field of auxiliary devices for equipment processing, and more specifically, to a hydraulic device for equipment processing. Background Technology

[0002] In modern machining industries, reliable clamping devices are indispensable for the precise machining of workpieces. Traditional clamping methods and equipment have many problems, which seriously affect machining quality and production efficiency.

[0003] Some clamping devices have simple structures, insufficient clamping force, and difficulty in evenly distributing it, which makes the workpiece prone to displacement or shaking during processing. For example, some mechanical clamping methods rely solely on simple screws or clamps for fixation. When faced with complex processing techniques or large processing forces, they cannot guarantee the stability of the workpiece, thus greatly reducing processing accuracy and resulting in a high defect rate.

[0004] In addition, traditional clamping equipment has poor versatility, often only capable of clamping workpieces of specific shapes or sizes. Once the specifications of the workpiece change, the entire clamping device needs to be replaced, which not only increases production costs but also extends the production cycle, failing to meet diverse production needs.

[0005] Meanwhile, the installation and disassembly of some clamping devices are cumbersome, requiring specialized tools and complex operating procedures. This wastes a significant amount of time and manpower during equipment maintenance, workpiece replacement, or process adjustment, reducing the overall efficiency of the equipment.

[0006] Moreover, some existing clamping devices lack effective positioning and fixing measures, making it difficult to accurately align with processing equipment, thus affecting the accuracy and stability of processing. Utility Model Content

[0007] Based on the above-mentioned technical problems, this utility model proposes a hydraulic device for equipment processing.

[0008] A hydraulic device for machining includes a base, which serves as the fundamental support for the entire device. Fixed screws are installed at all four corners of the base to securely fix it to the machining equipment, ensuring that the base does not shift during machining. Multiple symmetrically distributed grooves are formed in the center of the base, allowing the clamping force to be evenly applied to the workpiece placed at the center. Clamping seats that slide along the grooves are installed within the grooves. A hydraulic cylinder is located at the rear end of the grooves and is connected and fixed to the clamping seats. The hydraulic cylinder provides power to the clamping seats, pushing them to move along the grooves, thereby achieving the clamping and releasing operation of the workpiece.

[0009] The clamping seat has a detachable clamping head on the inside. This design allows for easy replacement of the appropriate clamping head when dealing with workpieces of different shapes and sizes, improving the versatility of the equipment. The bottom of the slide has a bottom groove, which is an inverted T-shaped groove. The lower part of the clamping seat has a limiting part that matches the bottom groove. The cooperation between the inverted T-shaped groove and the limiting part can effectively prevent the clamping seat from falling out of the slide during the sliding process, enhancing the stability and reliability of the equipment operation.

[0010] Preferably, the base has a positioning groove on its lower side, which matches the positioning protrusion on the workstation of the processing equipment. This design enables the base to be quickly and accurately positioned in the appropriate position on the processing equipment when installing hydraulic equipment, improving the accuracy and efficiency of installation and ensuring precise docking between the hydraulic equipment and the processing equipment.

[0011] Preferably, the fixing screw and the base are rotatably connected. The lower part of the fixing screw is provided with external thread. The lower end of the fixing screw is aligned with the positioning screw hole on the processing equipment and tightened. This rotatable connection method makes it more convenient to install and disassemble the fixing screw. Furthermore, the height of the base can be changed by rotating the fixing screw to adapt to clamping requirements of different heights.

[0012] Preferably, the upper part of the clamping seat is provided with a fixing screw hole, and the clamping head is provided with a mounting screw hole aligned with the fixing screw hole. After the mounting screw hole is aligned with the fixing screw hole, it is tightened with bolts and nuts. This connection method is simple and reliable, and facilitates quick disassembly and installation when the clamping head needs to be replaced.

[0013] Preferably, the inner end of the mounting screw hole is provided with an embedded groove, which is concentric with the mounting screw hole, and the bolt nut is embedded in the embedded groove. The embedded groove can prevent the bolt nut from protruding from the surface of the clamping head, thus avoiding damage to the workpiece surface when clamping the workpiece. It also makes the appearance of the clamping head flatter, which is conducive to better fit to the workpiece.

[0014] Beneficial effects:

[0015] 1. Stable and uniform clamping: The circumferentially symmetrically distributed grooves and hydraulically driven clamping seats can provide uniform and powerful clamping force, effectively preventing the workpiece from shifting or shaking during processing, greatly improving processing accuracy and reducing product defect rate.

[0016] 2. High versatility: The detachable clamping head design allows the equipment to adapt to workpieces of various shapes and sizes without the need for frequent replacement of the entire clamping device, reducing production costs, shortening the production cycle, and meeting diverse production needs.

[0017] 3. Easy installation and disassembly: The rotating connection between the fixing screw and the base, and the connection between the clamping head and the clamping seat via bolts and nuts, make the installation, disassembly and maintenance of the entire hydraulic equipment simple and quick, saving a lot of time and manpower and improving the efficiency of equipment use;

[0018] 4. Precise positioning: The positioning groove on the underside of the base matches the positioning protrusion on the processing equipment station, ensuring precise docking between the hydraulic equipment and the processing equipment, further improving the accuracy and stability of processing;

[0019] 5. Protect the workpiece: The embedded groove design at the inner end of the mounting screw hole avoids damage to the workpiece surface caused by bolts and nuts, which helps protect the appearance and quality of the workpiece. Attached Figure Description

Detailed Implementation

[0026] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0027] like Figures 1-5 The hydraulic device shown is used for equipment processing. The specific implementation process and clamping principle of this device are as follows:

[0028] 1. Equipment installation: First, clean the workstation of the processing equipment to ensure that there are no debris on the surface of the positioning protrusion. Then, align the positioning groove 12 on the lower side of the base 1 of the hydraulic equipment with the positioning protrusion on the workstation of the processing equipment to initially position the base 1. Next, by rotating the fixing screws 6 at the four corners of the base 1, tighten the external thread at the lower end of the fixing screws 6 with the positioning screw hole on the processing equipment, thereby firmly fixing the base 1 to the processing equipment.

[0029] It should be noted that if it is necessary to adjust the height of the base 1 on the workstation, it can be done by rotating the fixing screw 6. The principle is that the fixing screw 6 and the base 1 are rotated together, that is, the base 1 is located on the upper part of the fixing screw 6. The upper part of the fixing screw 6 has no external thread, so the base 1 will not move up and down along the fixing screw 6. The fixing screw 6 is relatively long, and a section of its lower part is exposed to facilitate changing the distance between the base 1 and the workstation.

[0030] 2. Installation of clamping head 7: Select a suitable clamping head 7 according to the shape and size of the workpiece to be processed. Align the mounting screw hole of clamping head 7 with the fixing screw hole on the upper part of clamping seat 3. Pass the bolt 9 through the mounting screw hole and the fixing screw hole, and then screw the nut 10 on the other end of the bolt 9 and tighten it to fix the clamping head 7 inside the clamping seat 3.

[0031] It is important to note in this step that the nut of bolt 9 must be inserted into the recessed groove 8 at the inner end of the mounting screw hole.

[0032] 3. Workpiece clamping and processing: Place the workpiece in the center of the base 1, start the hydraulic cylinder 11, and the hydraulic cylinder 11 pushes the clamping seat 3 to move along the slide 2 toward the workpiece until the clamping head 7 contacts and clamps the workpiece. At this time, the processing equipment can be started to process the workpiece.

[0033] As the clamping seat 3 moves along the slide groove 2, its inverted T-shaped limiting part 5 slides along the bottom groove 4. The cooperation between the bottom groove 4 and the limiting part 5 can effectively prevent the clamping seat 3 from coming out of the slide groove 2 during the sliding process, which can enhance the stability and reliability of the equipment operation.

[0034] 4. Workpiece release and equipment disassembly: After processing, control the hydraulic cylinder 11 to move in the reverse direction, so that the clamping seat 3 drives the clamping head 7 to release the workpiece. If it is necessary to replace the workpiece or perform equipment maintenance, the bolts 9 and nuts 10 that fix the clamping head 7 can be unscrewed first, and the clamping head 7 can be replaced. If the entire hydraulic equipment is to be disassembled, rotate the fixing screw 6 to separate it from the positioning screw hole on the processing equipment, and the base 1 can be removed from the processing equipment.

[0035] Through the above specific embodiments, the hydraulic equipment for equipment processing of the present invention can efficiently and stably complete the clamping operation of the workpiece, providing strong support for equipment processing. The above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. For those skilled in the art, the present invention can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
