Put, including hollow body, gripping block, power transmission component, contiguous block, cover plate, push rod and power set, the body is interior to be arrived in the past
After the gripping block, power transmission component, contiguous block and cover plate be installed, the power transmission component includes butterfly spring, force-transmitting block, cylinder
Spring, guide rod and guide pad, butterfly spring are arranged between rear end and the force-transmitting block of gripping block, and the push rod is close to tail
Diameter increase suddenly to be to form a step at portion, the gripping block be circumferentially provided with it is multiple be used to installing the push rod and with institute
State step and form the stepped hole being slidably matched, the back-end central of gripping block is provided with a screwed hole for being used to install guide rod, passed
The centre of power block is provided with a through hole, and the guide rod passes through the through hole, and the guide pad centre is provided with a use
In the stepped hole for penetrating guide rod, the cylindrical spring is arranged between force-transmitting block and guide pad and is set with the guide bar, institute
State contiguous block to be fixedly connected with guide pad, contiguous block centre is provided with a through hole for being used to install the power set, institute
State and one is provided with the middle part of cover plate is used for the through hole that contiguous block penetrates, cover plate is fixedly connected with body.
The butterfly spring is multilayer and its external profile diameter is less than composition on the inside of 3 larger cylinders of push rod tail diameter
Diameter of a circle.
Coupled between the cover plate and body, between contiguous block and guide pad using soket head cap screw.
Beneficial effects of the present invention are：Mechanism is ingenious, simple in construction, easy to use, is total in cylindrical spring and butterfly spring
Workpiece is clamped under same-action, workbench or other fixtures are withstood in push rod, push rod produces reaction force to force-transmitting block,
In the case where thickness of workpiece is certain, if power set power continues to increase, push rod produces reaction force to force-transmitting block to be caused
Force-transmitting block can not continue to move to gripping block, so as to keep clamping force constant to avoid being caught broken brittle workpiece.
Brief description of the drawings
Fig. 1 is the structural representation of the present invention；
Fig. 2 is the complete section schematic diagram of the present invention；
Fig. 3 is embodiments of the invention schematic diagram；
Fig. 4 is the left view in Fig. 1.
Embodiment
The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, apparent is clearly defined so as to be made to protection scope of the present invention.
As Figure 1-Figure 4, the clamping device of a kind of Double-spring constant force control, including hollow body 1, gripping block 2,
Power transmission component, contiguous block 8, cover plate 9, push rod 10 and power set 14, the gripping block is installed from front to back in the body 1
2nd, power transmission component, contiguous block 8 and cover plate 9, the power transmission component include butterfly spring 3, force-transmitting block 4, cylindrical spring 5, guide rod 6
With guide pad 7, butterfly spring 3 is arranged between rear end and the force-transmitting block 4 of gripping block 2, and the push rod 10 is at afterbody
Diameter increase suddenly to form a step, the gripping block 2 be circumferentially provided with it is multiple be used to installing the push rod 10 and with institute
To state step and form the stepped hole being slidably matched, the back-end central of gripping block 2 is provided with a screwed hole for being used to install guide rod 6,
The centre of force-transmitting block 4 is provided with a through hole, and the guide rod 6 passes through the through hole, and the centre of guide pad 7 is provided with
One stepped hole for penetrating guide rod 6, the cylindrical spring 5 are arranged between force-transmitting block 4 and guide pad 7 and are sleeved on guiding
On bar 6, the contiguous block 8 is fixedly connected with guide pad 7, and the centre of contiguous block 8 is provided with one and is used to install the power dress
14 through hole is put, the middle part of cover plate 9 is provided with one and is used for the through hole that contiguous block 8 penetrates, and cover plate 9 is fixedly connected with body 1, work
When making, the push rod 10, which is withstood in frame, is used for the mounting surface for placing workpiece.
The butterfly spring 3 is multilayer and its external profile diameter is less than on the inside of 3 larger cylinders of the tail diameter of push rod 10
