Intensity.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model clamping device；
Fig. 2 is the structural schematic diagram of check body in the utility model clamping device.
In figure, 1. clamp base, 2. column oil har openings, 3. check body fixing seats, 4. check bodies, 5. resetting apparatuses.
Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, a kind of check clamping device with initial clamping force of the utility model, including rectangular clamping base
1, it clamps 1 center of base and offers column oil har opening 2.Even circumferential setting along column oil har opening 2 is inverse there are four check body 4
Only 4 body cross-section of body is the rectangle that one group of opposite side is in 1/4 circular arc, and the 1/4 circular arc homodromic deflection of group, 4 main body of check body
Upper and lower surface centre be respectively and fixedly connected with a cylindrical body, and two cylindrical bodies are coaxial, and the path length of two cylindrical bodies is consistent, two
The height of cylindrical body is consistent (as shown in Figure 2).Check body 4 is bolted to connection with check body fixing seat 3, and check body is fixed
Seat 3 is bolted to connection with base 1 is clamped.Be provided with resetting apparatus 5 on check body 4, resetting apparatus 5 include a spring and
One cuboid spring mounting post, cuboid spring mounting post are fixed in a side of the non-cambered surface of check body 4, and spring one end is affixed
In side of the spring mounting post far from column oil har opening 2, the other end of spring is fixed in check body fixed pedestal 3 far from column oil
The inner wall of the side of cylinder holes 2.
The utility model has the working principle of the check clamping device of initial clamping force are as follows: the main function of the utility model
Energy part is check body, and 4 body cross-section of check body is the rectangle that one group of opposite side is in 1/4 circular arc, and 1/4 circular arc of group is in the same direction
Deflection, with the increase of linear velocity, eccentric distance is continuously increased, and forms wedge-shaped clamping mechanism.
The utility model has the course of work of the check clamping device of initial clamping force are as follows: moves column oil cylinder dismantling machine
It moves to working region, the utility model clamping device is installed on the corresponding position of column oil cylinder dismantling machine, then, by column
Oil cylinder passes through column oil har opening 2, clamps guide sleeve with the guide sleeve retaining part of column oil cylinder dismantling machine, then, starts column
Oil cylinder disassembles machine, and guide sleeve starts to rotate counterclockwise, when initial, because guide sleeve is closely connect with column oil cylinder, therefore, column
Rotation counterclockwise therewith, i.e. column oil cylinder are rotated along 4 circular arc of check body direction from low to high, due to the effect of resetting apparatus 5,
4 column oil cylinder outer wall of check body forms initial clamping force.When column oil cylinder dismantling machine drives column oil cylinder to reversely rotate, i.e.,
When rotating clockwise, due to the effect of frictional force, check body 4 is reversely rotated, i.e. rotation counterclockwise, with column oil cylinder linear velocity
Increase, the reversed clamping force of 4 column oil cylinder of check body increases with it (formed wedge-shaped clamping mechanism), and guide sleeve is gradually split
It removes.Then, it closes column oil cylinder and disassembles machine, the linear velocity of column oil cylinder is gradually reduced, the folder between column oil cylinder and check body 4
Clamp force is gradually reduced, and after column oil cylinder stops operating, column oil cylinder is taken out from the utility model clamping device, finally,
Check body 4 resets under the action of resetting apparatus 5.
