Description
Technical field
The utility model relates to the technical field in Structure of Mechanical Parts, the design of specifically a kind of pull rod is to be applied to
For connecting the pull rod of hollow chuck and solid oil cylinder in mechanical equipment.
Background technique
In mechanical equipment, the clamp system using hydraulic hollow chuck and solid angling cylinder is a kind of in machine industry
Using the method for clamping that extremely wide part is processed, part is completed to the reliable grip of part by the claw of oild chuck
Cutting, hydraulic power is the claw for being transferred to chuck by pull rod by the oil cylinder of lathe tail portion.The mechanism structure is simple, performance can
Lean on and can be improved the degree of automation of lathe.Traditional pull rod design for connecting hollow chuck and solid oil cylinder is using monoblock type
Structure, though rigidity wastes material (for unitary solid bar) or period longer (for forging and forming) well and manufacturing procedure is multiple
Miscellaneous, the process-cycle is long.Therefore, it is necessary to design, a kind of rigidity is preferable, the processing is simple and economical and practical welded type connecting rod
To substitute traditional monoblock type pull rod.
Utility model content
Goal of the invention: the utility model provides a kind of economical and practical, property to overcome the deficiencies in the prior art
It reliably welded type pull rod can be used to connect hollow chuck and solid oil cylinder.
Technical solution: in order to solve the above technical problems, the utility model adopts the following technical solution:
A kind of pull rod connecting hollow chuck and solid oil cylinder, including chuck swivel nut connector 1, long pipe sleeve 3 and cylinder connector
4, wherein the chuck swivel nut connector 1 is connect by chuck connecting flange 7 with the hollow chuck 8 of right end, the cylinder connector 4
It is connect by oil cylinder connecting flange 6 with the solid oil cylinder 5 of left end, the long pipe sleeve 3 is located at chuck swivel nut connector 1 and cylinder connector
Between 4.
Further, connected between the chuck swivel nut connector 1, cylinder connector 4 and the long pipe sleeve 3 of centre by welding manner
It is connected in integral structure.
Further, the long pipe sleeve 3 selects seamless steel pipe.
Further, further include U type slot, the left side shaft shoulder of pull rod is set, for cooperating special tooling spanner to exist
It is used when pull rod is installed, the boss of special tooling spanner setting is matched with the U type slot size of the pull rod.
Further, the O-ring seal 2 for further including O-shaped seal groove and being mounted in O-shaped seal groove, O-shaped seal groove setting
In the periphery of chuck swivel nut connector 1, for preventing coolant liquid from entering machine tool chief axis inner hole.
The utility model has the following beneficial effects:
As the design of one of mechanical equipment Structure of Mechanical Parts, processing and manufacturing cost, and the pull rod are reduced
Design structure is simple, processing technology is simple, reliable, and there is good rigidity, economic and practical and novel, more particularly to
Into the machinery field for the clamp system for configuring hydraulic hollow chuck and solid angling cylinder.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Appended drawing reference therein are as follows: chuck swivel nut connector 1, O-ring seal 2, long pipe sleeve 3 and cylinder connector 4, solid oil cylinder
5, oil cylinder connecting flange 6, chuck connecting flange 7, hollow chuck 8.
Specific embodiment
1 pair of the utility model is further described with reference to the accompanying drawing.
As shown in Figure 1, the hollow chuck and the pull rod of solid oil cylinder described in the utility model of connecting includes that chuck swivel nut connects
First 1, O-ring seal 2, long pipe sleeve 3 and cylinder connector 4.Chuck swivel nut connector 1 is connected with the chuck of right end, cylinder connector 4 and left
The oil cylinder 5 at end connects, and the long pipe sleeve 3 of chuck swivel nut connector 1, cylinder connector 4 and centre is allowed to be integrated by welding procedure
That is solid oil cylinder 5 of the welded type pull rod for hollow chuck 8 and left side on the right side of connecting machine tool.Welding back stay blank, there are one
Fixed deformation, in order to guarantee the machining accuracy of part, according to processing technology, the chuck swivel nut connector 1,4 and of cylinder connector
Long pipe sleeve 3, which is both needed to stay before welding, puts certain processing chipping allowance, and welding back stay blank carries out multiple tracks work as integration
Sequence is processed to meet the morpheme size tolerance and roughness requirements of drawing.
The material of the long pipe sleeve 3 requires to select the seamless steel of suitable national standard specification according to the size of inner hole and outer diameter
Pipe, had not only had economy but also had reduced machining allowance.
The shaft shoulder is arranged a U type slot and is used to cooperate the use when installing pull rod of special tooling spanner on the right side of the pull rod,
The boss of special tooling spanner setting must be matched with the U type slot size of the pull rod.
An O-shaped seal groove assembly sealing ring, which is arranged, in the pull rod in large cylindrical prevents coolant liquid from entering in machine tool chief axis
Hole.For good sealing effect, the O-ring seal 2 (considers pull rod intensity) under conditions of pull rod is permitted, and line footpath is most
It may be more greatly.
Chuck connecting flange 7 is arranged in hollow 8 inside of chuck and is located at the outside of chuck swivel nut connector 1.Oil cylinder connection method
Orchid 6 is arranged between solid oil cylinder 5 and scuffing of cylinder bore.
To optimize above-mentioned technical proposal, the concrete measure taken further include:
Pull rod is connected by screw thread with hollow chuck and solid oil cylinder, to guarantee that the accuracy class of pull rod connection screw thread is wanted
It asks, the left and right screw thread of the welded type pull rod is required to postwelding processing.
The above is only the preferred embodiment of the utility model, it should be pointed out that: for the common skill of the art
For art personnel, without departing from the principle of this utility model, several improvements and modifications can also be made, these improve and
Retouching also should be regarded as the protection scope of the utility model.
