Abstract
The utility model relates to a friction welder with highly reliable structure. For decades, friction welding technique keeps developing and is limited by the development of processing equipment at present. Because friction welding procedure needs to be accomplished with high pressure and a large number of revolutions, a mainshaft load bearing not only rotates at a high speed but also bears strong axial working pressure in the welding process. Therefore, the service life of the bearing is extremely short, the integral reliability index of the equipment is influenced, and great waste is caused to a user; and the user needs to replace the bearing frequently. The utility model comprises a friction welder bed body, wherein, rotating chucks are respectively arranged at both ends of a central driving wheel (3) which is connected with a mainshaft (2) of the friction welder bed body; a pair of coaxial clamping devices (8) are arranged correspondingly to workpiece chucks; and a pair of sliding clamping devices are installed on a slideway of a tail bracket of the bed body. The utility model is applied to friction welding.
Description
Technical field:
The utility model relates to a kind of high reliability structure friction-welding machine.
Background technology:
Friction welding technique sustainable development in decades has been subjected to the restriction of process equipment development so far.Because friction-welding technique needs high pressure, high revolution is finished.The load bearing is not only being born the task of rotation at a high speed, but also to bear powerful axial operating pressure in the welding procedure, cause the working life of this bearing extremely short, thereby influence equipment whole reliability index, cause great waste to the user, often change bearing.
Summary of the invention:
The purpose of this utility model provides a kind of friction-welding machine that can eliminate the high reliability structure of the powerful axial compressive force of main shaft bearing.
Above-mentioned purpose realizes by following technical scheme:
High reliability structure friction-welding machine, its composition comprises: friction welding (FW) lathe body, rotary chuck is equipped with at the center drive two ends that the main shaft of described friction welding (FW) lathe body connects respectively, corresponding to described workpiece chuck a pair of same shaft clamping device is housed, described a pair of sliding fixture is installed on the slideway of tailstock of described bed body.
The beneficial effects of the utility model:
The welding operation simultaneously of the utility model two bond pads workpiece, application of force direction is relative, and operating pressure is cancelled out each other.The axial force that this bearing bore is zero, thereby reaches the purpose in the service life of very big prolongation bearing, has alleviated the overall weight of equipment simultaneously, thereby has improved the equipment whole reliability, has saved great deal of steel, and operating efficiency has improved nearly one times.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present utility model.
The specific embodiment:
Embodiment 1:
The new structure friction-welding machine, its composition comprises: the agent structure of the friction-welding machine of prior art comprises drive mechanism and fuselage 1, the main shaft of friction-welding machine originally is that an end contacts with rotational workpieces 5 by rotary chuck 4, axial force when bearing friction welding by bearing, the main shaft 2 of this product contacts with workpiece by two chucks that driving wheel 3 two ends are provided with, carry out friction welding at two ends, the axial force of having cancelled out each other.Be equipped with a pair of with shaft clamping device 8 corresponding to described workpiece chuck, be used to tighten the workpiece 7 of stationary end, described sliding fixture is installed on the slideway of tailstock 10 of described bed body, can apply the friction welding equilibrant force of equity by tailstock or sliding fixture.
The rotary chuck 4 that is described new structure friction-welding machine is fixed on the main shaft 2 by bearing 9, and described rotary chuck 4 is connected with rotational workpieces 5, and described rotational workpieces 5 connects operation with static workpiece 7 by friction and produces friction welding face 6.
Its work main points are a pair of sliding fixture applies welding (equal and opposite in direction, direction is opposite) synchronously to central principal axis friction pressures.Causing the suffered axial force of main shaft bearing is zero.
Claims (1)
1. high reliability structure friction-welding machine, its composition comprises: friction welding (FW) lathe body, it is characterized in that: rotary chuck is equipped with at the center drive two ends that the main shaft of described friction welding (FW) lathe body connects respectively, corresponding to described workpiece chuck a pair of same shaft clamping device is housed, described a pair of sliding fixture is installed on the slideway of described bed body tailstock.
