A kind of Height Adjustable connection handle
The present invention relates to metal forming machinery technical field, especially a kind of Height Adjustable connection handle.
Existing upper die of bending machine clamp system has mechanical and fluid pressure type, be mechanically manually slack adjuster and realize
The release and clamping of upper mould, because mounting screw is more, there is (each mounting clamp skill amount size is different) in human factor, and it is present
The deficiency of length of not clamping and die change time, the needs of modern production far can not be realized；Fluid pressure type be by installed in
Ejecting force caused by hydraulic cylinder on a certain pressing plate and clamp mould.In order to improve existing upper die of bending machine clamp system, market
On there are many improvement mechanisms, these follow-on clamp systems for convenience be connected with Digit Control Machine Tool, mostly can at top
Connection handle is installed, but the most structure of these connection handles is fixed, and can not highly be adjusted with structure, causes the rule of corresponding Digit Control Machine Tool
Lattice extremely limit to, and the scope of application is very single.
The content of the invention
The technical problem to be solved in the present invention is：In order to solve problem present in above-mentioned background technology, there is provided Yi Zhonggai
The Height Adjustable connection handle entered, solve to fix currently used for the most structure of the connection handle of clamp system, highly can not with structure
The problem of regulation, the specification for causing to correspond to Digit Control Machine Tool are extremely limited to, and the scope of application is very single.
The technical solution adopted for the present invention to solve the technical problems is：A kind of Height Adjustable connection handle, including connection
Handle body, described connection handle body lower end are welded with the fixed plate with inner bolt hole, described connection handle body interior
Longitudinal direction offers longitudinal drive cavity, and the left side being connected with inside longitudinal drive cavity is offered on described connection handle body left side wall
Control mouth is put, is offered on described connection handle body right side wall and puts control mouth with the right side being connected inside longitudinal drive cavity, institute
The connection handle body right side wall stated is put to offer above control mouth positioned at the right side puts lifting with the right side being connected inside longitudinal drive cavity
Mouthful, the corresponding right side puts hatchway position and is provided with clamp and lower clamp on the right side of described connection handle body, described upper clamp and
Lower clamp left end is respectively provided with driver plate, and described driver plate upper and lower end has been fixedly connected with extrusion spring, described longitudinal transmission
Intracavitary portion is longitudinally connected with the left screw and right screw being parallel to each other, and described left screw upper end is through driver plate on the inside of upper clamp
It is threadedly coupled with upper clamp, described right screw upper end is threadedly coupled through driver plate on the inside of lower clamp with lower clamp, described
Control mouth position is put positioned at a left side in left screw and be fixedly connected with left-handed button for controlling left screw to rotate, in described right screw
Positioned at the right side put control mouth position be fixedly connected with for control right screw rotate dextrorotation button.
Further, the through hole corresponding with right screw is offered on the driver plate on the inside of the upper clamp.
Further, a described left side puts control mouth and the right side to put control open height identical and size is identical.
Further, described through hole internal orifice dimension is more than right screw overall diameter.
The invention has the advantages that a kind of Height Adjustable connection handle of the present invention, by connection handle body interior
The longitudinal drive cavity for built-in two screw mandrels is opened up, controls and adjust respectively the height of upper and lower clamp using the knob on screw mandrel
Degree and spacing so that the connection handle structure is adjustable, and control mode is simple and convenient, and the scope of application greatly enhances.

In conjunction with the accompanying drawings, the present invention is further explained in detail.These accompanying drawings are simplified schematic diagram, only with
Illustration illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of Height Adjustable connection handle shown in Fig. 1 and Fig. 2, including connection handle body 1, the weldering of the lower end of connection handle body 1
Connect and be fixed with the fixed plate 2 with inner bolt hole, the inside of connection handle body 1 longitudinal direction offers longitudinal drive cavity 3, connection handle body 1
Offered on left side wall and put control mouth 4 with the left side being connected inside longitudinal drive cavity 3, offered on the right side wall of connection handle body 1
Control mouth 5 is put with the right side being connected inside longitudinal drive cavity 3, and the right side wall of connection handle body 1, which is located at the right side, to be put the top of control mouth 5 and open up
Have and put hatchway 6 with the right side being connected inside longitudinal drive cavity 3, the setting of the position of hatchway 6 is put on the corresponding right side in the right side of connection handle body 1
There are upper clamp 7 and lower clamp 8, upper clamp 7 and the lower left end of clamp 8 are respectively provided with driver plate 9, and the upper and lower end of driver plate 9 is fixedly connected with
There is extrusion spring 10, be longitudinally connected with the left screw 11 and right screw 12 being parallel to each other inside longitudinal drive cavity 3, in left screw 11
End is threadedly coupled through the upper inner side driver plate 9 of clamp 7 with upper clamp 7, and the lower inner side driver plate 9 of clamp 8 is run through in the upper end of right screw 12
It is threadedly coupled with lower clamp 8, putting the position of control mouth 4 positioned at a left side in left screw 11 is fixedly connected with for controlling left screw 11 to rotate
Left-handed button 13, put the position of control mouth 5 positioned at the right side in right screw 12 and be fixedly connected with dextrorotation for controlling right screw 12 to rotate
Further, the through hole 15 corresponding with right screw 12 is offered on the driver plate 9 of the upper inner side of clamp 7, further
Ground, control mouth 4 is put on a left side and the right side puts that control mouth 5 is highly identical and size is identical, and further, the internal orifice dimension of through hole 15 is more than right screw
12 overall diameters, a kind of Height Adjustable connection handle of the invention, it is used for built-in two silks by being opened up inside connection handle body 1
The longitudinal drive cavity 3 of bar, the height and spacing of upper and lower clamp 8 is controlled and adjusted respectively using the knob on screw mandrel so that the company
It is adjustable to connect handle structure, control mode is simple and convenient, and the scope of application greatly enhances.
