Abstract
Provided is a locating tool for a cylinder barrel of a steering oil cylinder of a forklift. The locating tool for the cylinder barrel of the steering oil cylinder of the forklift comprises a connection chassis and a central spindle connected to the center of the chassis, the central spindle is sleeved with an inner-diameter brace piece and a supporting ring, a small block shaft penetrates through the central spindle and is connected to the center of the connection chassis, the small block shaft presses the inner-diameter brace piece and the supporting ring on the central spindle through a gland, the connection chassis and the central spindle are connected through an inner hexagon screw and a spring washer, the small block shaft is connected with the chassis through a thread, and an O-type ring is installed outside the supporting ring. The locating tool for the cylinder barrel of the steering oil cylinder of the forklift is simple in structure, convenient to operate and high in practicability and reliability, and well solves the problem that the cylinder barrel is difficult to locate when being machined. Meanwhile, by means of the locating tool, the machining processes are reduced, the machining efficiency is improved, and especially the concentricity of two end hole threads is improved greatly.
Description
Technical field
The utility model relates to field of machining, especially a kind of fork-truck steering cylinder tube positioning tool.
Background technology
Oil cylinder [1] is the device that utilizes fluid pressure to carry out transferring power and control in hydraulic support, mainly cylinder body, piston rod, piston and sealing parts etc., consists of.In these parts of oil cylinder, the cylinder barrel processing in cylinder body is the most complicated, and its endoporus dimensional accuracy is high, and roughness value is little, and will guarantee the cylindricity of endoporus, the axiality requirement of two head threads.Existing processing method positioning difficulty is large, and manufacturing procedure is many, is difficult to guarantee the machining accuracy of cylinder barrel.
Summary of the invention
For guaranteeing machining accuracy, the utility model proposes a kind of fork-truck steering cylinder tube positioning tool, comprise connecting base plate and the mandrel that is connected to chassis central authorities, mandrel outer casing internal diameter support sheet and support ring, the little axle of push and block is connected to connecting base plate center through mandrel, and the little axle of push and block, by gland, internal diameter is supportted to sheet and support ring is pressed on mandrel; The described chassis that connects adopts soket head cap screw to be connected with spring shim with mandrel, and the little axle of described push and block is connected employing and is threaded with chassis, and described support ring is equipped with O type circle outward.
The beneficial effects of the utility model are: tool structure is simple, easy to operate, and practicality and reliability are high, have solved well in cylinder barrel processing and have located difficult problem.Use this frock to reduce manufacturing procedure simultaneously, improved working (machining) efficiency, particularly the axiality of hole, two screw thread is required to be greatly improved.
Accompanying drawing explanation
Fig. 1 fork-truck steering cylinder tube positioning tool master looks cutaway view
Reference numeral: 1-connecting base plate, 2-soket head cap screw, 3-spring washer, 4-mandrel, 5-internal diameter support sheet, 6-support ring, the little axle of 7-push and block, 8-O type circle, 9-gland.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
A kind of fork-truck steering cylinder tube positioning tool as shown in Figure 1, comprise connecting base plate 1 and the mandrel 4 that is connected to chassis central authorities, mandrel 4 outer casing internal diameter support sheet 5 and support rings 6, the little axle 7 of push and block is connected to connecting base plate 1 center through mandrel 4, and the little axle 7 of push and block, by gland 9, internal diameter is supportted to sheet 5 and support ring 6 is pressed on mandrel 4; The described chassis 1 that connects adopts soket head cap screw 2 to be connected with spring shim 3 with mandrel 4, and the little axle 7 of described push and block is connected employing and is threaded with chassis 1, the outer O type circle 8 that is equipped with of described support ring 6; In figure, frock outside dotted portion is workpiece to be processed fork-truck steering cylinder tube.
A kind of fork-truck steering cylinder tube positioning tool using method: connecting base plate is arranged on to lathe three and grabs on chuck, then cylinder tube is enclosed within to frock outside, then rotating the little axle of push and block makes internal diameter support sheet and support ring external diameter become large, thereby tensioner cylinder barrel clamps cylinder barrel from endoporus, so just can while turning and internal thread.
