Description
Technical field
The present invention relates to the press-loading device applied technical fields of machinery manufacturing technology field more particularly to heavy load, specifically
It is related to a kind of single input multistation heavy load pressure head automatic switching control equipment.
Background technique
In industrial automation, the press-loading device of heavy load using very universal, pressure assembling force range from 3T to 30T not
Deng.According to the design structure and assembly technology of components, usually requires that and multiple components are pressed using same positioning datum, due to
The press fitting force parameter of these components is different, when press-loading device is pressed these components, before positioning tool remains unchanged
It puts, press-loading device needs to be pressed these components using different pressure heads.In the prior art, it is usually changed planes fastly by pressure head
Structure mode and press-loading process split mode to be pressed the different components of press fitting force parameter.Wherein, pressure head quick-changing mechanism mainly by
One heavy load press fitting actuator, a force snesor, a pressing head seat and multiple pressure heads composition, pressure head and pressing head seat pass through axis
Hole cooperation, and fixed by rotation pin or holding screw, when replacing different pressure heads, manually rotation pin is extracted or unclamped
Holding screw.It is that the part that will need to be pressed is split on equal number of station or station and presses that press-loading process, which splits mode,
It fills, is configured in each station or station a set of by a heavy load press fitting actuator, a force snesor and a press head group
At press-loading device.
But for pressure head quick-changing mechanism mode, when replaceable pressure head, need that manually rotation pin is extracted or unclamped tight
After determining screw, then original pressure head unloaded, then install new pressure head, then rotation pin is screwed in or tightened clamp screw
Nail, it is difficult to which the continuous automatic press mounting for realizing multiple parts influences production efficiency；In addition, in order to realize press fitting function, heavy load pressure
The corresponding pressure head heavier-weight of mounting mechanism is required to staff's quick change press head, working strength in each press fitting working cycles
Danger big and there are pressure head landing, jeopardizes the security of the lives and property of personnel.For press-loading process fractionation mode, each
The part that difference press fitting requires is required to configure a set of press-loading device, and heavy load press fitting actuator and force snesor therein belong to
Expensive in high-precision equipment, input cost is high；And press-loading process is split to equal number of station or station, equipment
Space greatly increases, deficiency in economic performance.
Therefore, one of ordinary skill in the art need to research and develop a kind of heavy load pressure head mechanism for automatically switching, mitigate staff
Labor intensity under the premise of guaranteeing worker safety, improves production efficiency.
Summary of the invention
In view of this, the technical problem to be solved in the present invention is that provide a kind of single input multistation heavy load pressure head automatic
Switching device, solves that existing press-loading device production efficiency is low, and labour intensive is more, and there are problems that security risk.
In order to solve the above-mentioned technical problem, a specific embodiment of the invention provides a kind of single input multistation heavy load pressure
Head automatic switching control equipment, comprising: guide rod；Rack is arranged on the guide rod, and the rack is moved along the guide rod；
Docking mechanism is arranged in the rack, for docking with press fitting actuator；Multiple-station rotation mechanism is arranged in the rack
On, for switching the pressure head of power output.
Above-mentioned specific embodiment according to the present invention it is found that single input multistation heavy load pressure head automatic switching control equipment extremely
Have the advantages that there is pressure head automatic switching control equipment a press fitting actuator input interface and the installation of multiple pressure heads to connect less
Head is successively acted on the power output for being pressed actuator by the automatic switchover of the pressure head automatic switching control equipment to multiple pressure heads
On pressure head, multiple and different press fitting parameter request parts are pressed using same positioning datum, equipment occupation space is few, realizes
Multiple pressure heads accurately automatically switch and lock, and switching precision is high, and press fitting quality is stablized.Meanwhile manual intervention replacement is not needed
Pressure head reduces artificial working strength, greatly improves production efficiency；Heavy load is pressed the power outbound course of actuator and work is pressed
Head is coaxial, can anti-stop-band moment of flexure press fitting, the service life of mechanism is high, has efficiently automatic, at low cost, time saving and energy saving, safety can
The advantages that leaning on, be compact-sized.
