The cramping apparatus has simple structure and convenient use, a PCB board sample can be clamped through the clamping mechanism and can be directly placed on a cut film grinding machine for grinding and polishing, the step of using a special-purpose transparent box for packing and fixing PCB boards in the original art is saved, and the cramping apparatus is convenient for operation, and lowers inspection cost.
Description
Technical field
The utility model relates to a kind of anchor clamps, specifically is meant a kind of PCB section clamp for grinding that uses in the PCB testing process.
Background technology
In the PCB manufacturing, for guaranteeing PCB production board quality, various tests and check are absolutely necessary.Wherein a kind of pcb board slice probing is performed such: at first take a sample on pcb board with punch press, then sample is placed in the dedicated transparent box, and fix with quick epoxy encapsulation, again with metallographic grinder with the sample sanding and polishing, at last with microscopic examination and measure.During detection, because sample is fixed in the transparent box, can not adjust sightingpiston, make and detect inconvenience, required transparent box can only be used once i.e. calcellation in said process in addition, and it is higher that it detects cost.
The utility model content
The utility model is intended to solve the cost height, the sightingpiston that exist in the above-mentioned PCB slice probing and is difficult for the problem of adjustment, and then a kind of PCB section clamp for grinding is provided.
For addressing the above problem, the technical scheme that the utility model is taked is: a kind of PCB section clamp for grinding, the clamping device that can relative support on comprising support and being installed on support moves up and down, this clamping device comprises two clamping limbs, two clamping limbs are the spring jaw type and connect, the lower end is provided with fastening spring between two clamping limbs by the pin pin joint together, and two clamping limb lower ends are clamped condition under the fastening spring nature.
A kind of concrete scheme is: a clamping limb of described clamping device is installed on the support by two bearings, is provided with gear on the support between two bearings in addition, establishes the adjustment handle on the gear, and this clamping limb side correspondence is established the sliding rail of tooth bar and loading bearing.Pull the adjustment handle, driven gear rolls along the tooth bar of clamping limb side, and the reaction force of gear can drive whole clamping device and move downward or upward, to adjust the height of clamping device.
Preferably, be provided with strut between described two clamping limbs, strut one end is fixed on the clamping limb, and the other end vertically passes another clamping limb, and this clamping limb strut relatively slides, and spring housing is connected on the strut; The end that described strut stretches out clamping limb is provided with push rod, and this push rod is vertical with strut and be connected by pin.
The utility model is simple for structure, and is easy to use; It clamps the pcb board sample by clamping device can be placed directly into grinding and polishing on the metallographic grinder, has saved and has used the fixedly step of pcb board of dedicated transparent box encapsulation in the conventional art, is convenient to operation, and has reduced the detection cost.
Description of drawings
Fig. 1 forms schematic diagram for the utility model structure.
The specific embodiment
For ease of it will be appreciated by those skilled in the art that the utility model is described in further detail below in conjunction with drawings and Examples.
As shown in Figure 1, described PCB section grinding clamp comprises support 1, is installed on the support 1 clamping device 2 that support relatively moves up and down.Described clamping device 2 comprises that left clamping limb 11, right clamping limb 12, two clamping limbs below link together by pin, and is provided with spring 10 between two clamping limbs, and this spring struts two clamping top positions, makes two clamping limb lower ends be clamped condition.
As figure, during use support 1 is fixed to grinder 100 tops, clamping device 2 clamps the PCB section after the sampling, makes its position correspondence on the grinding rotating disk 101 of grinder, and starter motor grinds rotating disk 101 and rotates, and realizes grinding and polishing to the PCB section.
Be handled easily, described clamping device 2 support relatively moves up and down.Among the embodiment, this structure is by get at 2 on support 1 vertical direction two bearings to be set, and a place establishes a gear 16 between the two bearings.The corresponding sliding rail 121 of establishing loading bearing on clamping limb 12 vertical directions, two bearings is installed on this track and can slides up and down in this track; The tooth bar 122 of also corresponding setting of the side of right clamping limb 12 and gear 16 interlocks is established on the gear 16 and is adjusted handle 17.Upwards pull and adjust handle 17, gear scrolls up along the tooth bar 122 of clamping limb 12 sides, and two bearings is corresponding the slip along the slide rail road, and the reaction force of gear can promote whole clamping device 2 and move downward; Reverse pulling handle 17, clamping device 2 moves up, and realizes Height Adjustment.
Clamping device 2 relies on the support power of fastening springs 10, under the nature about two clamping limb lower ends be clamped condition.Among the embodiment, set firmly a strut 13 above right clamping limb 12, strut 13 vertically passes clamping limb 11, and spring 10 is socketed on the strut 13; The end that this strut 13 stretches out clamping limb 11 is provided with push rod 14, and push rod 14 and strut 13 is vertical mutually and be connected by pin.Promote push rod 14 to the right, spring 10 closes up on two clamping limbs by compression, and then unclamp the lower end, conveniently replaced pcb board section.
The foregoing description only is a preferred implementation of the present utility model, and in addition, the utility model can also have other implementations.That is to say that under the prerequisite that does not break away from the utility model design, any conspicuous replacement and minor variations all should fall into protection domain of the present utility model.
