Description
Technical field
The present invention relates to assembly small tool field, specifically a kind of core-theaded type cylindrical screw pressure spring pre-tightening apparatus.
Background technique
Cylindrical screw pressure spring is used widely in production as a kind of mechanical energy storage element.In production and application,
The structure type of some products is the pressure spring being placed in counterbore, because of the restriction by the space assembled when this pressure spring is installed,
Cause that pressure spring is difficult to install, craftsmanship is poor, working efficiency is low, particularly the biggish pressure spring of elastic force, safety are poor.Such as a kind of end
Pressure type floor, pressure spring one end head on the counterbore of end floor side, and other end heads on wallboard, and wallboard and floor side it
Between gap≤12mm., this floor pressure spring is to pull tight pressure spring in advance to be placed in the counterbore of floor in advance using its perfect condition,
It is placed in beside wallboard again, waits Integral floors all to lay and remove pressure spring preload again, make it at natural compressive state, and it is this
Up to the present core-theaded type cylindrical screw pressure spring pre-tightening apparatus not yet occurs in the market.
Summary of the invention
The purpose of the present invention is to solve drawbacks described above present in existing pressure spring installation operating procedure, provide a kind of letter
Just the manual pre-tightening apparatus of practical cylindrical screw pressure spring makes pressure spring facilitate installation under compression, heavy suitable for being placed on
The installation of pressure spring used in hole.
The purpose of the present invention is achieved through the following technical solutions: a kind of manual cylindrical screw pressure spring preload dress of core-theaded type

Specific embodiment
Present invention is further described in detail with reference to the accompanying drawing, and the embodiment is only for explaining the present invention, not structure
At limiting the scope of the present invention.
As shown in Fig. 1 ~ 9, the present invention includes a kind of manual cylindrical screw pressure spring pre-tightening apparatus of core-theaded type, including adjustable bottom feet
1, bottom plate 2, liner plate 3, guide sleeve 4, pressing plate 5, L shape barrier support 6, L shape screw bracket 9 and pressure spring to be installed 17；The adjustable bottom
The upper end of foot 1 is connected with bottom plate 2, and the both ends of the bottom plate 2 are connected separately with L shape barrier support 6 and L shape screw bracket 9, in institute
It states and is connected with liner plate 3 on the bottom plate 2 between L shape barrier support 6 and L shape screw bracket 9, the L shape screw bracket 9 and screw rod 7
It is spirally connected, 7 tail end of screw rod and rotational handle 8 are affixed, and the guide sleeve 4 is placed on liner plate 3, and the pressing plate 5 is pressed in guiding
On set 4, the pressing plate 5 is vertical with hold-down bolt 10 to be connect, the hold-down bolt 10 is spirally connected with dish shape nut 11, the compression spiral shell
Bolt 10 and it is vertical with bottom plate 2 connect, the L shape barrier support 6 is hinged with one end of lever 12, at the both ends of the guide sleeve 4
It is equipped with stretching screw and pays 16, wirerope lock 15 is equipped in one end close to the L shape screw bracket 9, in the wirerope
Wirerope 13 is connected on lock 15；The barrier support is parallel with L screw bracket to be installed, and each two supporting surface is all orthogonal；
The center of the L shape barrier support 6 is provided with round tube hole 601, is symmetrically provided with above the through-hole 601 along vertical center line
Through slot 602；The through-hole 601 and guide sleeve 4 of the L shape barrier support 6 and the screw hole 901 of L shape screw bracket 9 are in same central axis
Line；The internal diameter of the guide sleeve 4 and outer diameter, the outer diameter of the screw rod 7 and the internal diameter of interior guide sleeve 14 of support sleeve 15 are gap
Cooperation；The internal diameter of the length > pressure spring 17 to be installed of the wirerope lock 14；Spherical pit is provided in the end of the screw rod 7；
The hinged center of the lever 12 is higher than 6 through hole center of L shape barrier support, and upper edge is following lower than 6 through-holes of L shape barrier support
Edge, the spiral shell, 7 ends are provided with spherical pit；(13 ~ 16 be the pre- required auxiliary material of pressure spring in figure).
Working principle of the invention is as follows:
By the wirerope for putting on belt lock catch in 17 centre bore of pressure spring to be installed, (screw round end or lock diameter are necessarily less than outside screw rod
Diameter) or cheese head screw, pressure spring together with the wirerope of screw rod or belt lock catch is then placed in 4 inner hole of guide sleeve and by screw
Then guide sleeve 4 is adjusted to and 601 center of barrier support hole, the screw rod by head or lock end against the screw rod 7
The same center line of 7 axis, rotational handle 8 make 7 head end of screw rod push head of screw or first button and advance together with pressure spring tail portion along axis,
It since pressure spring head end is blocked by the barrier support hole 601, and compresses pressure spring 17 to be installed along interior guide sleeve, is compressed to pressure spring
To when requiring length, screw just is lockked with nut or steel cord ends lock locks wirerope, due to there is the support of support sleeve 14,
It ensure that the straightness of compressed pressure spring；Then by compressed pressure spring i.e. together with screw pay or wirerope and head and the tail latch into
Nut or wirerope head button bit for convenient for finally unlocking, therefore need to be set and be stayed in outside counterbore by preset counterbore.It is installed to pressure spring carrier
After in place, remove nut or the wirerope head that comes loose buckled, pressure spring hold out against state naturally.
The invention has the following advantages that
