Specific embodiment
As shown in Figure 1, including in the present embodiment: linear slide mechanism a, front end hold-down mechanism b and pedestal fixed transfer machine
Structure c, in which: pedestal fixed transfer mechanism c is fixedly connected with linear slide mechanism a, the both ends of camera lens d to be measured and side difference
It is in contact with pedestal fixed transfer mechanism c, front end hold-down mechanism b and linear slide mechanism a.
As shown in Fig. 2, the linear slide mechanism a includes: fixed block 7, rotation stick harness 8, stop screw 9, U-shaped bloom
10, extension spring 11, limited post 12, sliding block, line slide rail 14, top shoe 17 and the pre- bearing seat 18 of camera lens.
The top shoe 17, sliding block pass through the auxiliary slider of at least three sunk screws 9 and line slide rail 14 respectively
15 and line rail 16 it is fixed, so that sliding block is only axially had freedom degree in camera lens.
The pre- bearing seat 18 of the camera lens is fixed with top shoe 17 by least three sunk screws 9, and actually camera lens is pre-
Bearing seat 18 is not close to camera lens, and there are small gaps, prevent camera lens deformation as caused by Planar Mechanisms, guarantees performance.
The top shoe 17, sliding block passes through limited post 12 respectively, cheese head screw 9 is connected with a spring, it is therefore an objective to
Make have restoring force between two sliding blocks.
The top shoe 17 is connected by sunk screw 9 and fixed block 7 with rotary plunger.
The sliding block inlays U-shaped bloom 10 in specific position x, and the rotary plunger being connected with top shoe 17 can automatic clamping
In U-shaped bloom 10, when pull-up rotary plunger, front end hold-down mechanism can be automatically springed open, but due to stop screw 9
In the presence of the fixing end and movable end of fixture can maintain within the scope of certain distance, due to the presence of U-shaped bloom 10, spiral stick harness 8
Abrasion with sliding block substantially reduces, and increases the service life of fixture.

The bottom of plate 3 is connected by least three sunk screws 9 with sliding block, and through-hole 4 there are four setting, and elastic 1 bottom end of steel column is equipped with
Ring-shaped groove 2, and 3 through-hole 4 of pressing plate is passed through, stub end blocks towards camera lens and built-in spring, 2 end of groove backwards to camera lens, C-shaped ring 6
The firmly ring-shaped groove 2 of elastic steel column 1, during compressing fixture gradually, the top of elastic steel column 1 first contacts the screw of camera lens
9, spring is slowly compressed until rotary plunger is caught in U-shaped bloom 10 later, and the pressing force of pressing plate 3 acts on the screw of camera lens at this time
At 9, there is also pretightning force when due to camera lens mounting screw 9, this power will not make when the compression of pressing plate 3 almost on performance without influence
The performance change of camera lens.
As shown in figure 3, the pedestal fixed transfer mechanism c includes: general-purpose interface adapter ring 20 and camera lens positioning seat 19,
Wherein: general-purpose interface adapter ring 20 can be directly installed on projection light machine, and the camera lens fixture of any size may be designed to
Size accordant interface, come the projection light machine for cooperating factory unified, lens fixing base passes through at least three screws 9 and general-purpose interface
Adapter ring 20 is fixed, and general-purpose interface adapter ring 20 is equipped with several 9 holes of screw, and lens fixing base is equipped at least three sunk screws 9
Arc groove 21, when entire fixture screws in ray machine by general-purpose interface adapter ring 20, line rail 16 not necessarily in the underface of fixture,
For convenience of producing line clamping, lens fixing base and general-purpose interface adapter ring 20 can freely be arranged in pairs or groups by rotation and sunk screw 9 and be reached
The purpose that can be fixed to any angle, lens fixing base is kept by the positioning column of location hole and camera lens and camera lens optical axis connects
It is close to be overlapped.
Above-mentioned specific implementation can by those skilled in the art under the premise of without departing substantially from the utility model principle and objective with
Different modes carries out local directed complete set to it, and the protection scope of the utility model is subject to claims and not by above-mentioned specific
Implementation is limited, and each implementation within its scope is by the constraint of the utility model.
