Abstract
The invention relates to the field of mechanical auxiliary devices, in particular to a fixture for turning a piston combustion chamber. The fixture for turning the piston combustion chamber comprises a connecting disc with a boss, and a threaded sleeve. The fixture for turning the piston combustion chamber is characterized in that the boss of the connecting disc is connected with a left lock nut and a right lock nut through threads, the left lock nut and the right lock nut are connected through a bolt, the boss of the connecting disc is connected with a rabbet disc by a bolt, the threaded sleeve penetrates through the center of the connecting disc and is in threaded connection with a pull ring which penetrates through the center of the rabbet disc, a pull rod is arranged at the other end of the pull rod, the axis of the pull rod is perpendicular to the axis of the pull ring, and one end of the pull rod is connected with the right lock nut through a connecting piece. The fixture for turning the piston combustion chamber has the advantages that the structure is simple, the fixture is simple to operate, the combustion chamber position adjusting accuracy is high, the adjusting time spent by workers during process machining is greatly shortened, the working efficiency is improved and the machining waste is reduced.
Description
Technical field
The present invention relates to assist field, be specifically related to turning piston combustion bowl fixture.
Background technology
Piston is the critical moving components in internal combustion engine, and it bears alternate load repeatedly at high temperature under high pressure, is called as the heart of internal combustion engine.Along with the fast development that internal combustion engine requires to high pressure, high-power, low emission, also more and more higher to the requirement on machining accuracy of piston, and piston-top surface combustion chamber is the power source of piston, the processing of piston combustion bowl is the important component part of Piston Machining, main processing method has forming cutter to process, hydraulic tracing control is processed, numerical control.Due to widely using of Digit Control Machine Tool, processing piston combustion bowl with Digit Control Machine Tool has become main processing mode.Especially all the more so for the unmanageable eccentric piston of combustion chamber of abnormity.During with Digit Control Machine Tool machining piston combustion chamber. without the need to again with difform forming-tool and pattern, only need the procedure changing part can be in eccentric position by engine piston combustion chamber center opposing pistons cylindrical axis majority.Various piston bias is inconsistent.And position accuracy demand is very high, locating and machining is very difficult.Traditional piston combustion bowl eccentric combustion chamber fixture is just used as shift fork with a montant.Pull-rod is not fixed at circumferencial direction. and when easily there is gap between pull-rod and pull bar after tension, positioning precision is very poor.Moreover when processing different piston product variety, the position adjustment of montant also comparatively bothers.
Summary of the invention
In order to solve the problem, the invention provides a kind of structure simple, easy to operate, high to position, combustion chamber Adjustment precision, greatly shorten workman operation processing in regulation time, increase work efficiency, reduce processing waste product turning piston combustion bowl fixture.
A kind of turning piston combustion bowl of the present invention fixture, comprise the terminal pad with boss and silk braid, the boss of described terminal pad is threaded connection left locking nut and right locking nut, described left locking nut is connected by bolt with right locking nut, described terminal pad boss has been bolted a seam dish, described silk braid is through the center of terminal pad, and be threaded with the draw ring through seam disk center, the other end of described draw ring is provided with a pull-rod, the axis of pull-rod and the axis perpendicular of draw ring, described pull-rod one end is connected with right locking nut by connector.
Preferably, connector is a shift fork, and described shift fork one end to be arranged on terminal pad and to be bolted together, is provided with pull-rod in the socket of the described shift fork other end.
Preferably, shift fork is a thin plate has a U-shaped opening, and the both sides of U-shaped opening are equal to the distance on thin plate both sides.
Structure of the present invention is simple, easy to operate, high to position, combustion chamber Adjustment precision, greatly shorten the regulation time of workman in operation processing, increase work efficiency, and reduces processing waste product.

Fig. 1 is the structural representation of turning piston combustion bowl fixture.
Fig. 2 is shift fork top view.
Reference numeral: 1-terminal pad, the left locking nut of 2-, the right locking nut of 3-, 4-shift fork, 5-pull-rod, 6-silk braid, 7-draw ring, 8-seam dish.
Detailed description of the invention
Turning piston combustion bowl fixture of the present invention, comprise the terminal pad 1 with boss and silk braid 6, the boss of described terminal pad 1 left locking nut 2 and right locking nut 3 have been threaded connection, described left locking nut 2 is connected by bolt with right locking nut 3, described terminal pad 1 boss has been bolted a seam dish 8, described silk braid 6 is through the center of terminal pad 1, and be threaded with the draw ring 7 through seam dish 8 center, the other end of described draw ring 7 is provided with a pull-rod 5, the axis of pull-rod 5 and the axis perpendicular of draw ring 7, described pull-rod 5 one end is connected with right locking nut 3 by connector.Connector is a shift fork 4, and described shift fork 4 one end to be arranged on terminal pad 1 and to be bolted together, is provided with pull-rod 5 in the socket of described shift fork 4 other end.Described shift fork 4 is a thin plate has a U-shaped opening, and the both sides of U-shaped opening are equal to the distance on thin plate both sides.
By rotating two locking nuts, shift fork 4 position be in a circumferential direction embedded on locking nut can be adjusted arbitrarily in a circumferential direction, adjust the tension direction of the pull-rod 5 be connected with shift fork 4 simultaneously, then left locking nut 2 and right locking nut 3 are carried on the back tightly by bolt, the position of shift fork 4 just secures.Be threaded owing to adopting between locking nut with terminal pad 1, fine setting can be realized, by the tensioning function of silk braid 6, draw ring 7, piston is made to be fixed on position, determination direction on seam dish 8, by the two-way location of shift fork 4, pull-rod 5 is fixed at circumferencial direction, and operator's adjustment is got up easily, and positioning precision is high; The present invention has that method of adjustment is simple, positioning precision is high, greatly can shorten the tool setting time of workman in operation processing, the feature of processing cost of increasing work efficiency, save.
