Abstract
The utility model discloses an auxiliary supporting device for a floor type machine tool, which comprises two sets of carrier roller assemblies and a connecting rod, wherein the carrier roller assemblies comprise carrier rollers and carrier roller seats, and the two sets of carrier roller assemblies are connected together through the connection between the connecting rod and the two carrier roller seats; and the auxiliary supporting device is characterized in that the connecting rod is connected with the carrier roller seats in a hinged manner. With the adoption of the auxiliary supporting device, adaptive follow-up of the carrier roller seats can be realized under the action of a smaller force under the condition that a cylindrical workpiece has a larger cylindricity error so as to ensure the carrier rollers to be always in good contact with the cylindrical workpiece to ensure the carrier rollers to be only subjected to a radial force all the while to guarantee the machining accuracy and stability of a cylinder.
Description
Technical field
The utility model relates to a kind of auxiliary support apparatus that processing is used above the large-diameter cylinder body workpiece of the equipment range of work on face lathe.
Background technology
When the process equipment standard is with interior large-diameter cylinder body workpiece on face lathe, generally take an end to fix with the floral disc claw, the other end is with the fixing installation way of tailstock thimble.When barrel diameter is bigger, when the cylindrical shell quality exceeds the thimble weight capacity, need adorn a backing ring at the cylindrical of cylindrical shell, the mode that adopts carrying roller to support backing ring is then processed.When barrel diameter is increased to a certain degree, if adorn a backing ring at the cylindrical shell cylindrical, be subjected to the high restriction in lathe center, the distance between backing ring and the lathe flat board will can not load carrying roller, therefore can only remove backing ring, with the direct supporting workpiece of carrying roller in the auxiliary support apparatus.Existing auxiliary support apparatus two groups of idler assemblies and a connecting rod is again formed, and the roller seat in connecting rod and the idler assembly is rigidly connected.Because the cylindrical shell workpiece is generally rolled by coiling machine and forms, there are certain deviation from circular from and deviation from cylindrical form in its surface, and general barrel diameter is big more, and these errors are also just big more.The unescapable deviation from cylindrical form of cylindrical shell workpiece can constantly change cylindrical shell and carrying roller contact wire, and being rigidly connected between connecting rod and two roller seats can't be made follow-up adjustment to carrying roller, thereby influences the stability and the precision of the processing of cylindrical shell workpiece.
The utility model content
The purpose of this utility model is to provide a kind of auxiliary support apparatus that is used to land lathe, to guarantee the stability and the machining accuracy of the super scope large-diameter cylinder body workpiece of face lathe processing.
The utility model provides this auxiliary support apparatus that is used to land lathe, comprise two groups of idler assemblies and connecting rod, described idler assembly comprises carrying roller and roller seat, connecting rod is characterized in that by connecting together with making two groups of idler assemblies being connected of two roller seats being connected to of described connecting rod and roller seat is hinged.
A quarter butt is respectively arranged on described two roller seats, and two carrying rollers are by quarter butt and described rod hinge connection.Described quarter butt is connected with roller seat.
The utility model two roller seats because and rod hinge connection, when cylindrical shell workpiece deviation from cylindrical form bigger, when cylindrical shell and carrying roller contact wire can constantly change, roller seat produces adaptive servo-actuated under the effect that is subjected to less power, to adapt to the variation of contact wire, make carrying roller keep excellent contact with the cylindrical shell workpiece all the time, allow carrying roller only be subjected to radial load all the time, thereby guarantee the machining accuracy and the stability of cylindrical shell.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is a vertical view of the present utility model.
The specific embodiment
That land machine tooling as can be seen from Fig. 1 and Fig. 2 is the cylindrical shell workpiece A of a super-large diameter, is being supported by the utility model auxiliary support apparatus.The utility model comprises two groups of idler assemblies 1 and connecting rod 2, and idler assembly 1 is on the dull and stereotyped B of lathe, and it comprises on carrying roller 11 and roller seat 12, two roller seats and is connected with a quarter butt 13 respectively, and the two ends of connecting rod 2 are hinged with two quarter butts 13 respectively.So that carrying roller keeps excellent contact with the cylindrical shell workpiece all the time, allow carrying roller only be subjected to radial load all the time, thereby guarantee the machining accuracy and the stability of cylindrical shell.
