Floating pressure head device

Abstract

The invention discloses a floating pressure head device. The floating pressure head device comprises an oil distributing base, a base, an index plate, a positioning plate and multiple pressure head assemblies in a sequential overlaying mode. Multiple through installation grooves are formed in the base and the index plate. The pressure head assemblies are correspondingly arranged in the installation grooves. Each pressure head assembly can horizontally move in the corresponding installation groove. A cavity is formed in the oil distributing base, and the oil distributing base is provided with an oil filling port which leads to the cavity. A one-way valve is installed on the oil distributing base, and multiple oil outlets are respectively formed in the oil distributing base and lead to the cavity. Hydraulic hoses are correspondingly connected between the oil outlets and the pressure head assemblies. Hydraulic oil in all the pressure head assemblies is communicated, so that press fitting force of pressure heads of all the pressure head assemblies is even, press fitting is performed on each part in place, and press fitting precision is improved. Multiple parts can be pressed into the device in a one-off mode, so that time is saved, efficiency is improved, operation is convenient and cost is reduced, and the number of the pressure heads of all the pressure head assemblies can be designed according to workpieces.

Description

technical field [0001] The invention relates to the field of press-fitting devices, in particular to a high-precision floating press head device for simultaneously press-fitting multiple parts. Background technique [0002] In the mechanical press-fitting industry, when pressing multiple parts, the method often used is to vertically fix multiple indenters on a plate. When pressing parts, each indenter corresponds to multiple parts. , and then apply pressure to the entire plate, and transmit the pressure to the parts through the pressure head. In this method, the pressing force of multiple pressure heads is uneven, and the parts cannot be guaranteed to be in place at the same time, and the processing requirements are relatively high. There is also a method of press-fitting multiple parts one by one. This method has many press-fit steps, long press-fit time and low efficiency. Another method is to set multiple driving sources, each corresponding to a part, but this method is ...

When pressing parts, each indenter corresponds to multiple parts. , and then apply pressure to the entire plate, and transmit the pressure to the parts through the pressure head. In this method, the pressing force of multiple pressure heads is uneven, and the parts cannot be guaranteed to be in place at the same time, and the processing requirements are relatively high.

There is also a method of pressing multiple parts one by one. This method has many pressing steps, long pressing time and low efficiency.

Another method is to set up multiple driving sources, each corresponding to a part, but this method is costly and complicated to install
