Specific embodiment
The utility model is described in detail with reference to the accompanying drawings of the specification.
As shown in Figure 1, the anti-seamless special fixture of prism plated film in a kind of triangle provided by the utility model, including substrate
10, clamping device, clamping micro-adjusting mechanism and prefastening force adjustment mechanism.
Wherein for substrate 10 for connecting with coating machine, clamping device includes two support arms for being used for holding parts, two branch
Arm is worn on the substrate 10.
Clamping micro-adjusting mechanism includes the lock cylinder 20 being threaded through on two support arms, and lock cylinder 20 can move in the horizontal direction.
Specifically, the outer wall of lock cylinder 20 is equipped with the first screw thread, and support arm is equipped with the second spiral shell compatible with the first screw thread
Line, lock cylinder 20 are rotatably arranged on support arm, realize lock cylinder 20 in the horizontal direction by the relative rotation of the first screw thread, the second screw thread
Movement, structure is simple, easy to use.
As shown in Figures 2 and 3, ground is advanced optimized, lock cylinder 20 includes two the first lock cylinders being disposed in parallel on support arm
21 and second lock cylinder 22 being arranged in below the first lock cylinder 21, the second lock cylinder 22 pair of two the first lock cylinders 21 is set
Claim on line, make the second lock cylinder 22 and two the first lock cylinder 21 composition triangular shapes, and the lock cylinder 20 on two support arms is oppositely arranged,
The reliability for increasing Clamp blocks, prevents part from falling off in coating process, use is safer.
Support arm includes the connecting column worn on the substrate 10 and the connecting plate 41 for connecting column bottom is arranged in simultaneously, further
Optimally, connecting plate 41 includes the trapezoidal plate that the rectangular slab of connection column bottom is arranged in and is arranged in below rectangular slab, trapezoidal plate
Long bottom edge connect with rectangular slab.First lock cylinder 21, the second lock cylinder 22 may be arranged on connecting plate 41, reasonable utilization space, contracting
The volume of small entire fixture increases practicability.
Prefastening force adjustment mechanism includes the locking bar 30 being threaded through in lock cylinder 20, is equipped with bullet between 20 bottom of locking bar 30 and lock cylinder
Spring 31, the other end of locking bar 30 stretch out locking bar 30 and withstand part, keep part stress uniform, while can autonomous alignment jig clamping
Dynamics, avoid fixture high temperature deformation extrusion sections or expansion clearance be excessive that part is caused to fall off, increase the safety used
And reliability.
Substrate 10 is equipped with through-hole, and pillar 40 includes for first pillar fixed with connecting plate 41 and being arranged first
Second pillar of post top portion, the diameter of the first pillar are greater than the diameter of the second pillar, and the second pillar passes through through-hole, the first pillar
End withstand on the bottom surface of substrate 10, the end of the first pillar is locked by nut 50, and structure is simple, convenient for support arm to be fixed on
