Description

Multi-station hydraulic machining device

Technical Field

The utility model relates to the technical field of automatic production equipment, in particular to a multi-station hydraulic machining device.

Background

An automation device generally refers to an industrial production device which adopts an automatic control system and a detection device to process, convey, store and control and manage materials, semi-finished products and finished products in a production process. Currently, automation devices can be classified into stand-alone type automation devices and combination type automation devices; the single-machine type automatic equipment refers to: the single equipment consists of a host and an auxiliary device, has simple structure and convenient operation, is limited by a manufacturing process and is generally only suitable for small-scale production with small batch and multiple varieties. The combined type automatic equipment is as follows: the combination body with multiple functions formed by adding or reducing certain necessary components on the basis of a single machine type can meet the requirements of various products, the requirements of improving the reliability of the quality of the products and the like.

Both of the single-machine type automation equipment and the combined-type automation equipment require the use of processing aids, such as motorized jigs, etc. As the most widely used auxiliary devices in the machine industry, the motorized clamps can be generally classified into hydraulic drive clamps and pneumatic drive clamps. The pneumatic transmission clamp has the advantages that the clamping action is rapid, and the environmental pollution is avoided; and the automatic control is convenient, and the system faults are few. In the cutting process after clamping, the clamping force on the clamped workpiece is continuously maintained by mainly relying on the potential energy of compressed air, and energy is not consumed any more, so that the energy utilization rate of the pneumatic transmission clamp is high. However, the disadvantages are also obvious, and the main disadvantage is that compressed air is easy to leak; therefore, the system pressure is low, typically 0.4 to 0.7MPa, and thus, the defect of too small clamping force is easily caused. In contrast, the main advantages of the described hydraulically driven clamp are high system pressure and high clamping force. However, the main disadvantages are low energy utilization, loud noise of the hydraulic pump, and easy occurrence of environmental pollution caused by oil leakage and volatilization. Nevertheless, the use of hydraulically driven clamps is indispensable where clamping forces are required. The application range of the hydraulic transmission clamp disclosed by the prior art is narrow, clamping work of a single workpiece can be met, the installation structure of the existing hydraulic transmission clamp is complex, the disassembling and replacing steps are complicated, and the overall machining efficiency in the machining process is reduced.

Based on this, chinese patent CN116021314a discloses a hydraulic clamp comprising: the clamping mechanism comprises a positioning component and a jacking component. The base assembly comprises a base and a bridge plate, wherein the bridge plate is arranged on the base, a hydraulic channel is arranged in the bridge plate, a plurality of mounting positions are arranged on the bridge plate, and the hydraulic channel is communicated with a plurality of mounting positions. The positioning assembly and the propping assembly are arranged on the bridge plate at intervals along a first direction, the positioning assembly and the propping assembly are detachably connected with the mounting position, and hydraulic oil can be introduced into the hydraulic channel so that the positioning assembly and the propping assembly prop up and release a workpiece. The hydraulic clamp has the advantages of simple structural design, convenience in disassembly and assembly, wider application range and the like.

However, there is still room for improvement in the clamping efficiency of the hydraulically driven clamps disclosed above. Specifically, in the actual production application of the automation equipment, the auxiliary processing device capable of clamping only one attack at a time has a large influence on the rhythm of mechanical automatic production, and a user needs to continuously assemble and disassemble a clamp for processing the automation equipment so as to facilitate the feeding of workpieces to be processed and the blanking of the processed workpieces.
