Abstract
An automatic accessory-head tensioning mechanism belongs to the technical field of design and manufacture of automatic accessory-head tensioning mechanisms of heavy numerical control boring-milling machine. A wedge block is disposed between a pull hook and a piston, a positioning sleeve is sleeved outside the pull hook, a pull claw is disposed inside a pull claw notch, a pull claw positioning sleeve is disposed between the pull claw and a cylinder, and a rivet is disposed inside the pull claw. The automatic accessory-head tensioning mechanism is mounted inside four cavities of a transition connecting disc of a heavy numerical control boring miller, and is characterized in that oil inside the transition connecting disc enters from a lower oil inlet of the tensioning piston cylinder, the piston moves upwards to drive the wedge block to slide inside the piston, the positioning sleeve clamps the pull claw, and the pull claw catches the rivet. When the oil in the transition connecting disc enters from an upper oil inlet, the piston moves downwards to prevent the wedge block clamping the pull hook, the pull hook moves upwards to push the pull claw to unfold, and the rivet pops out when a spring inside the pull hook pushes a protective cover. When an accessory head is placed on a head removable machine, a slide base of a machine tool can move to a certain position, and the rivet on the accessory head can be grabbed by lifting a ram, thereby realizing the purpose of automatically tensioning and replacing.
Description
Technical field
The utility model belongs to the design and the manufacturing technology field of the automatic tensioning mechanism of heavy type numerical control boring and milling machine annex head.
Background technology
The manually-operateds of adopting that are installed of heavy type numerical control plane milling and boring machine annex head at present, the annex head is contained on the main shaft end face, with trip bolt it is fixed then more.This mounting means bothers very much, and labour intensity is also bigger.Because the weight of annex head itself is just heavier.When changing the annex head, at first to manually lay down it, change another annex head then, manually install again after the aligned position.Poor stability, inefficiency, the error ratio that manually is installed is bigger, can cause machining accuracy low.
Summary of the invention
It is little that the purpose of this utility model provides a kind of volume, easy for installation, and working pulling force is big, and loading and unloading can be saved the automatic tensioning mechanism of annex head of a lot of manpower and materials, to solve the problem that exists when existing annex head is installed.
Structure of the present utility model is as shown in drawings: piston is housed in cylinder body.In the inside of piston one drag hook is arranged.Centre at drag hook has spring.One voussoir is arranged between drag hook and piston.Voussoir is that drag hook plays the location.The certain position of suit cover outside the outside of drag hook.At the rear portion of drag hook one pulling claw mouth is arranged, grasping has a pulling claw in the mouth.One pulling claw positioning sleeve is arranged between pulling claw and cylinder body.Have blind flange at the cylinder body rear portion.There is a protective cover outside of spring.The inside at pulling claw has blind rivet.Hexagonal trip bolt on the periphery of flange, having.Fuel feed hole on the top of cylinder body has, bottom have following fuel feed hole.
Installation of the present utility model is four cavity the insides that it is installed in the transition terminal pad of heavy type numerical control plane milling and boring machine, fixes by the hexagonal trip bolt on the blind flange.Its operation principle is: when the oil in the transition terminal pad from the following fuel feed hole of tension piston cylinder when entering, piston moves up, and causes voussoir to slide at internal piston, positioning sleeve blocks pulling claw, pulling claw is caught blind rivet.When the oil in the transition terminal pad when last fuel feed hole enters, piston moves down, thereby makes voussoir no longer block drag hook, moves on the drag hook to promote pulling claw and open, blind rivet ejected when the spring in the drag hook promoted protective cover.When the annex head being put into when changing on the car, can allow the slide of lathe go to a certain position, grasp blind rivet on the annex head by the lifting of ram, realize the purpose that tension is automatically changed.Can reduce many work operations like this, improve efficient.Characteristics of the present utility model are, volume is little, and is easy for installation, are active in one's movements accurately, and working pulling force is big, and is safe and reliable, the automatic tensioning mechanism of annex head that efficient is high.
