Detailed description of the invention
For making the purpose of the present invention, content and advantage clearer, below in conjunction with the accompanying drawings and real Execute example, the detailed description of the invention of the present invention is described in further detail.
The invention provides a kind of circuit board clamp, such as accompanying drawing 1 circuit board clamp structure schematic diagram Shown in, accompanying drawing 2 is circuit board clamp front view, and accompanying drawing 3 is circuit board clamp side view.Circuit Board clamp includes the guide rod 1 being positioned at bottom, the bracing frame being slidably connected with guide rod 1, and is positioned at The clamping device on support top.
Specifically, as shown in Figure 1 and Figure 2, fixture includes 2 cylinder guides 1, leads for two Bar 1 be arranged in parallel.Bracing frame includes left support frame 5 and right support frame 10, left support frame 5 and the right side Bracing frame 10 is placed in parallel, bracing frame be cross section be the sheet material of triangle.Two jiaos of bracing frame Being fixed by guide rod 1, bracing frame realizes fastening, the top of bracing frame by screw 2 with guide rod 1 It is provided with clamping device.
Clamping device include successively along direction, guide rod 1 axis left chuck 6, right chuck 7, handle 8, Spring force regulating part 9 and spring 11.
Left chuck 6 is identical with the main part of the structure of right chuck 7, is: include a cylinder, The circuit board intermediate plate of cylindrical top welding U-shaped structure, cylindrical bottom is provided with annular Projection, annular protrusion has the effect of location.Except for the difference that, as it is shown in figure 5, the circle of right chuck 7 The bottom of cylinder is not only provided with annular protrusion 12, and cylinder is additionally provided with the installing hole 13 of handle 8, The axis direction of installing hole 13 is mutually perpendicular to cylindrical axis direction.Right chuck 7 and handle 8 Between be threaded.
Left support frame 5 top is provided with and coordinates the circular hole installed with left chuck 6, and circular hole is along left support frame Left support frame 5 is run through in 5 direction, plate faces, and left chuck 6 realizes fastening by screw 2 with left support plate 5; Fig. 6 is right support frame structural representation;Fig. 7 is Section A-A structure chart in Fig. 6;As it is shown in fig. 7, Right support frame 10 top is provided with the mounting groove of spring 11, and the cross section of mounting groove is for falling " mountain " word Structure, spring 11 is cylindrical spring, and spring is centrosymmetric distribution in mounting groove.Left support Being provided with back-up ring 3 between frame 5 and left chuck 6, the effect of back-up ring 3 is to reduce left support frame 5 and left folder Sliding friction between 6, and the tightness between bracing frame and chuck can be improved.
Fig. 4 is spring force regulating part structural representation;As shown in Figure 4, spring force regulating part 9 is Circular ring structure, annulus radial thickness closes with the mounting groove matching size on right support frame 10 top, bullet Spring force regulating part 9 with right support frame 10 for threadeding, when spring force regulating part 9 is to compression spring When the direction of 11 is tightened, can the clamping force of increasing circuit board clamp, when spring force regulating part 9 to When the direction of release spring 11 is tightened, then reduce the clamping force of circuit board clamp.
Right chuck 7 slides in right support frame 10, belongs to matched in clearance, and both constitute moving sets, Right chuck 7 is connected with right support frame 10 by threaded spring force regulating part 9, prevents right chuck 10 drop out right support frame 10 in sliding process.
Circuit board clamp operation principle:
1, clamping circuit board:
Hand steered circuit board 4, puts into circuit board 4 left end in left chuck 6, stirs handle 8 simultaneously Move right, compression spring 11;
By release handle 8 after the circuit board 4 right-hand member right chuck 7 of alignment, under spring force, Compress circuit board 4;Now, circuit board 4 is not limited around the degree of freedom of central rotation, arbitrarily may be used Adjust, when determining circuit board degree of freedom, screw 2 can be tightened to limit it around central rotation Degree of freedom;
Owing to circuit board ratio is relatively thin, poor rigidity, thrust is the most yielding, therefore need to enter spring force Row sum-equal matrix, spring force regulating part 9, for regulating the decrement of spring 11, regulates the work of spring 11 Firmly.
2, circuit board is unclamped:
Stir to the right handle 8, unclamp circuit board 4, taken off.
3, when needing the circuit board 4 clamping other dimensions, if being adjusted by regulation spring force Joint part 9 can not clamp circuit board 4, can unclamp screw 2 to adjust left support plate 5 and right support plate Distance between 10, thus meet the clamping to different size specification circuit board 4.
As can be seen from the above embodiments, the present invention is back-outed by being screwed into of spring force regulating part, The maximum compressibility of regulation spring, thus reach to regulate the purpose of the clamping force size of spring force, The clamping dynamics making circuit board is moderate, solve circuit board maintenance time move or rock ask Inscribing, and clamping thin-walled plate parts is unlikely to deform, clip clamp force is easy to adjust, positions, presss from both sides Tightly, work piece operations is unclamped convenient, reliably;Designed by the structure of clamping device so that circuit The plate face of plate can be positioned on arbitrarily angled, it is simple to dual platen is carried out prompt operation.Further, By regulation trip bolt, mobile left support plate and right support plate, sizes rule can be clamped The circuit board of lattice;After the piece-holder of a kind of specification completes, a labelling can be done on guide rod, So that the position of gripper shoe when quickly determining the clamping of different size size workpiece, improve clamping effect Rate.Present configuration is simple, convenient processing and manufacture;The size range of holding parts is big, is suitable for Scope is wide.
The above is only the preferred embodiment of the present invention, it is noted that lead for this technology For the those of ordinary skill in territory, on the premise of without departing from the technology of the present invention principle, it is also possible to Making some improvement and deformation, these improve and deformation also should be regarded as protection scope of the present invention.
