Abstract
Description
Technical Field
[0001] This utility model relates to a hydraulic component transfer fixture, which is particularly suitable for the handling and fixing of heavy hydraulic components such as hydraulic cylinders and hydraulic valves, and belongs to the technical field of mechanical processing auxiliary equipment. Background Technology
[0002] In the production, processing, and assembly of hydraulic components, transfer fixtures are often required for handling and securing these components. Hydraulic cylinders, valves, and other parts are typically heavy and irregularly shaped, making manual handling inefficient and posing safety hazards. Existing hydraulic component transfer fixtures mostly employ fixed clamping structures, which are ill-suited for hydraulic components of different sizes and shapes. Frequent fixture changes are necessary when transferring hydraulic components of varying sizes, increasing operating costs and time. Furthermore, improper fixture fit can lead to loosening or slippage of hydraulic components during transfer, causing damage or even accidents. Therefore, designing a transfer fixture capable of automatically adjusting the clamping force point and magnitude according to the different sizes of hydraulic components is of significant practical importance. Utility Model Content
[0003] Purpose of the utility model: The purpose of this utility model is to provide a hydraulic component transfer fixture. By adopting a linkage clamping method, the clamping force can be automatically adjusted according to the different dimensions of the hydraulic components to improve the versatility of the fixture and the clamping stability of the hydraulic components, thereby reducing operating costs and safety risks.
[0004] Technical Solution: This technical solution relates to a hydraulic component transfer fixture, including a base, a switch, a clamping mechanism, a top plate, guide columns, and a cylinder assembly. The cylinder assembly includes a cylinder and a piston rod. The cylinder is mounted on the top plate, and the piston rod extends downwards after passing through the top plate from below the cylinder. The lower end of the piston rod has external threads on its outer circumferential surface. The clamping mechanism includes a connecting plate assembly and multiple gripping rods. The connecting plate assembly has a threaded hole I at its center, which is adapted to the external threads of the piston rod. The piston rod and the connecting plate assembly can be connected and fixed through the external threads and the threaded hole I. The connecting plate assembly also includes multiple guide columns. The assembly includes a guide plate and multiple steering connecting plates. The guide plate has a through hole I through which a guide post can pass. The upper end of the guide post is fixed to the top plate, and the lower end is fixed to the base, allowing the connecting plate assembly to move vertically along the direction of the guide post. The gripper is an integrated structure consisting of a steering rod and a claw. The upper end of the steering rod is hinged to the steering connecting plate of the connecting plate assembly, and the lower end of the steering rod is movably connected to the base. When the connecting plate assembly moves vertically, the vertical angle of the steering rod changes, thereby causing the vertical angle of the claw to change, thus opening or closing the claw.
[0005] Specifically, the switch is fixedly installed on the base. The switch is equipped with air port I, and the cylinder is equipped with air port II. Air port I and air port II are connected by a pipe. The switch controls the air intake and exhaust of the cylinder, and the piston moves up and down, causing the connecting plate assembly to move along the vertical direction of the guide column, which in turn drives the gripper rod to move up and down, causing the claws to close and open.
[0006] Specifically, the base consists of multiple metal structural components and an inner ring base plate.
[0007] Specifically, the metal structural components include an outer ring base plate, an inner ring body, and a set of base connecting plates distributed at both ends. The outer ring base plate is welded and fixed to the inner ring base plate, and each base connecting plate is provided with screw holes II of the same size.
[0008] Specifically, the bottom of the steering rod is provided with a through hole II. The steering rod is placed between two base connecting plates of different metal structural components, and the through hole II is aligned with the screw hole II. The different metal structural components are connected and fixed by bolts and nuts, so that the bottom of the steering rod is fixed between the two base connecting plates and can rotate around the bolt, realizing the movable connection between the steering rod and the base.
[0009] Specifically, the base includes three metal structural components: six guide pillars, three guide plates, three steering connection plates, and three grab bars. Each guide plate has two through holes, and the six guide pillars pass through the six through holes.
[0010] Specifically, it also includes two overhead crane lifting rings, symmetrically arranged on the top plate, providing lifting points for cranes or overhead cranes, so that the hydraulic component transfer clamps can be easily lifted and moved onto transport vehicles.
[0011] Specifically, each base connecting plate is provided with no less than two screw holes II, which allows different metal structural components to be better fixed and connected, reducing loosening or displacement caused by external forces. Especially under large loads or vibrations, it can significantly improve the stability of the structure.
[0012] Specifically, a rectangular prism-shaped mounting block is set around the lower outer ring of the guide post, and the guide post is fixed to the base by welding the mounting block.
[0013] Beneficial effects: This utility model adopts a linkage clamping method, which drives the linkage assembly to move through a switching piston mechanism. It can automatically adjust the point of application and magnitude of clamping force according to different sizes of hydraulic components, eliminating the need for frequent clamp replacement, improving the versatility and work efficiency of the clamp, and reducing operating costs.

Detailed Implementation
[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions will be clearly and completely described below in conjunction with the accompanying drawings. All other embodiments obtained by those skilled in the art based on the described embodiments without inventive effort are within the scope of this disclosure.
[0021] Reference Figures 1-5 A hydraulic component transfer fixture includes a base 1, a switch 2, a clamping mechanism 3, a top plate 4, a guide post 5, and a cylinder assembly 6.
[0022] The base 1 consists of three metal structural components 11 and one inner ring base plate 12. Each metal structural component 11 includes an outer ring base plate 111, an inner ring body 112, and a set of base connecting plates 113 distributed at both ends. The outer ring base plate 111 and the inner ring base plate 12 are welded and fixed together to complete the basic structure of the base. Each base connecting plate 113 has two identical screw holes II114 for subsequent connection and fixing.
[0023] Switch 2 is fixedly installed on the base. Air port I on switch 2 is connected to air port II on cylinder 61 through a pipe to form an air circuit control structure.
[0024] The clamping mechanism 3 consists of a connecting plate assembly 31 and three gripping rods 32. The connecting plate assembly 31 includes three guide plates 311 and three steering connecting plates 312. Each guide plate 311 has two through holes I313, through which six guide posts 5 pass, allowing the connecting plate assembly to move vertically along the direction of the guide posts. The three gripping rods 32 are all integrated structures, consisting of a steering rod 321 and a claw 322. The upper end of the steering rod 321 is hinged to the steering connecting plate 312 of the connecting plate assembly 31, and the bottom end of the steering rod 321 has a through hole II323. The steering rod 321 is placed between two base connecting plates 113 of different metal structural parts 11, aligning the through hole II323 with the screw hole II114, and is fixed by bolts and nuts, allowing the bottom end of the steering rod 321 to rotate around the bolt, thus achieving a movable connection with the base.
[0025] Two crane lifting rings 7 are symmetrically installed on the top plate 4 to provide lifting points for cranes or overhead cranes. The rectangular column-shaped mounting blocks 8 on the lower outer ring of the six guide columns 5 are welded and fixed to the base 1, and the upper ends of the guide columns 5 are fixed to the top plate 4.
[0026] The cylinder assembly 6 includes a cylinder 61 and a piston rod 62. The cylinder 61 is mounted on the top plate 4. The piston rod 62 passes through the top plate 4 from below the cylinder and extends downward. The external thread on the lower outer circumference of the piston rod 62 is adapted to connect with the threaded hole I33 in the center of the connecting plate assembly 31.
[0027] When hydraulic components need to be transferred, the operator activates switch 2. Switch 2 controls cylinder 61 to release air, causing piston rod 62 to move upward, which in turn drives connecting plate assembly 31 to move vertically upward along guide post 5. Since the upper end of the steering rod 321 of gripper 32 is hinged to connecting plate assembly 31, and the lower end of steering rod 321 is movably connected to base 1, as connecting plate assembly 31 moves upward, the vertical angle of steering rod 321 changes, causing the vertical angle of claw 322 to change, thus gradually tightening claw 322.
[0028] During the tightening process, the claw 322 automatically adjusts the point of application and magnitude of the clamping force according to the shape and contour of the hydraulic component, stably holding the hydraulic component. Then, a crane or overhead crane hooks onto the overhead crane lifting ring 7 on the top plate 4, lifting the clamp holding the hydraulic component and moving it onto the transport vehicle, completing the transfer of the hydraulic component. Upon arrival at the destination, the operator operates switch 2 to allow air to enter cylinder 61, causing piston rod 62 to move downwards, connecting plate assembly 31 to move down, and claw 322 to open, unloading the hydraulic component.
[0029] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
