The purpose of the invention is as follows: in order to overcome the not enough of existence among the prior art, the utility model provides a PCB circuit board drilling location frock to prevent that the little deformation of PCB board from causing the drilling deviation.

The technical scheme is as follows: in order to achieve the purpose, the PCB drilling positioning tool comprises a positioning plate and a clamping plate, wherein the clamping plate is covered above the positioning plate; the positioning plate is provided with a fixed support column and is connected with at least one movable support column, and the fixed support column is provided with two baffle plates which are vertical to each other; the locating plate is connected with a lower guide sleeve in a sliding mode, the clamping plate is connected with an upper guide sleeve in a sliding mode, and the upper guide sleeve and the lower guide sleeve are opposite to each other from top to bottom in a sliding mode.

Furthermore, a plurality of fixing grooves which are perpendicular to each other are formed in the positioning plate, and the bottom ends of the movable support columns are connected into the fixing grooves.

Further, be connected with first guide arm and first screw rod on locating plate and the clamp plate respectively, first guide arm and first screw rod parallel arrangement, sliding connection has first fixed block on first guide arm and the first screw rod, be connected with second guide arm and second screw rod on the first fixed block respectively, second guide arm and second screw rod sliding connection have the second fixed block, go up uide bushing/down the uide bushing can dismantle to be connected on the second fixed block.

Furthermore, a groove is formed in the middle of the clamping plate, and a second fixing block connected to the clamping plate slides in the groove.

Furthermore, a plurality of clamping nails are connected to the second fixing block connected to the clamping plate.

Furthermore, the four corners department of locating plate is provided with the support column, the one end and one of them support column swivelling joint of pinch-off blades, the other end and another support column joint of pinch-off blades.

Has the advantages that: the utility model discloses a PCB drilling positioning tool, which is provided with an upper guide sleeve and a lower guide sleeve; when the PCB is drilled, the lower guide sleeve and the upper guide sleeve move to a preset position, the lower guide sleeve supports the PCB plate, micro deformation of the PCB in the drilling process can be reduced, and the accuracy of drilling is guaranteed.

Detailed Description

The present invention will be further described with reference to the accompanying drawings.

A drilling and positioning tool for a PCB comprises a positioning plate 1 and a clamping plate 2. Four corners departments of locating plate 1 upwards extend and form support column 17, pinch-off blades 2 are covered and are established 1 top of locating plate, one of them one corner of pinch-off blades 2 and one of them support column 17 swivelling joint, another corner department and another support column 17 joint of pinch-off blades 2. Specifically, a top bead is arranged at the other corner of the clamping plate 2, a limiting groove 18 is arranged on the top surface of one of the supporting columns 17, and the clamping plate 2 rotates to enable the top bead to be connected with the limiting groove 18 so as to relatively fix the positioning plate 1 and the clamping plate 2.

One of them support column 17 forms fixed support column 3 for the location PCB board, for the location is stable, still be connected with two movable support columns 4 on the locating plate. Two baffles 10 which are perpendicular to each other are arranged on the fixed support 3, the two baffles are respectively used for limiting the freedom degree of movement in the direction of X, Y, the movable support and the fixed support form a support plane for limiting the movement in the Z direction, and the freedom degree of rotation in the direction of X, Y achieves complete positioning. Specifically, a plurality of fixing grooves 6 perpendicular to each other are formed in the positioning plate 1, and the bottom ends of the movable pillars 4 are connected to the fixing grooves 6, so as to facilitate PCB boards of different sizes. Be connected with first guide arm 7 and first screw rod 8 on locating plate 1 and the clamp plate 2 respectively, first guide arm 7 and first screw rod 8 parallel arrangement, sliding connection has first fixed block 9 on first guide arm 7 and the first screw rod 8, be connected with second guide arm 11 and second screw rod 12 on the first fixed block 9 respectively, second guide arm 11 and second screw rod 12 sliding connection have second fixed block 13. The second fixing block 13 connected to the positioning plate is connected to the lower guide sleeve 5, and the second fixing block 13 connected to the clamping plate is connected to the upper guide sleeve 14. The first fixed block 9 can be driven to move by rotating the first screw 8, and the second fixed block 13 can be driven to move by rotating the second screw 12. The top end of the upper guide sleeve 14/lower guide sleeve 5 is provided with a flange which is pressed against the second fixed block 13, the upper guide sleeve 14/lower guide sleeve 5 and the second fixed block 13 form detachable connection, and the corresponding upper guide sleeve 14 and lower guide sleeve 5 are replaced when holes with different diameters are drilled.
