Present way is when part welds, to add part to set upright briquetting and reduce that part tilts, floating high level.This sets upright briquetting is to guarantee that its fit clearance scope of up and down smoothness of briquetting is all looser when setting upright guiding; Therefore when placement is fixedly set upright pressing plate; Receive the influence that pressure and spring force liquidate each other; Part can not guarantee to receive force direction fully perpendicular to horizontal direction in stressed moment, causes part welding back floating high, crooked, can't satisfy the shell matching requirements.
The utility model content
The purpose of the utility model is to overcome the deficiency that prior art exists, and provides a kind of PCB of being used for to cross the tool of stove location, can be convenient to the welding of part, and guarantees because of floating high, the crooked product process and poor welding tool that causes of part.
The purpose of the utility model realizes through following technical scheme:
A kind of PCB of being used for crosses the tool of stove location; Comprise the load plate and the pressing plate that is used for positioning component that are used to carry circuit board to be welded; Pressing plate is fastened on the top of load plate; Also be provided with several mechanical assistance positioners between pressing plate and the load plate and be used for fixing the positioner of electronic component with several, said positioner comprises screw thread guide wire, depression bar, part briquetting and the built-in spring that is fastened between pressing plate and the load plate.
Preferably, fixing between said load plate and the pressing plate through several fastening hook mechanisms connections.
Preferably, between pressing plate and load plate, be connected with four auxiliary locators, the setting that on pressing plate, is centrosymmetric of four auxiliary locators.
Further, said pressing plate is similar foursquare centrosymmetric image, and said four auxiliary locators are arranged on four angles of pressing plate.A supporting part briquetting of auxiliary locator and a built-in spring, auxiliary locator is arranged on the below of pressing plate, and part briquetting and built-in spring are connected in turn between auxiliary locator and the load plate.
Preferably, be fastened between pressing plate and the load plate to several screw thread guide wires and depression bar irregular alignment, said screw thread guide wire schedules on the pressing plate through screw thread and nut locking, and the inwall of screw thread guide wire is provided with guide hole, is with the guiding cover on the outer wall.
Compared with prior art, the advantage of the technical scheme of the utility model is:
1, utilizes the snap device of simple operation, significantly reduced operating personnel's operation complexity and labour intensity;
2, be utilized on four angles of positioning component fixed head auxiliary locator is set, can guarantee electronics
The stressed position of parts and positioning component fixed head activity direction are parallel to the load plate of circuit board fully;
3, spring adopts the built-in foreign matter of avoiding to be splashed into the normal use of influence;
4, utilize the screw thread guide wire, can carry out electrodeless adjusting pressure size and compression travel according to concrete part actual height;
5, utilize the guide hole of long and microgap, guarantee that positioning component movable smooth and easy and application of force direction when the application of force guarantees perpendicular to the positioning component fixed head.

The specific embodiment
In conjunction with Fig. 1-shown in Figure 3, a kind of PCB of being used for of the utility model crosses the tool of stove location, comprises the load plate 1 and the pressing plate 2 that is used for positioning component that are used to carry circuit board to be welded,
Pressing plate 2 is that similar foursquare center symmetry is dull and stereotyped, and pressing plate 2 is fastened on the load plate 1 at the symmetrically arranged fastening hook mechanism 3 of limit portion through two,
Also be provided with four mechanical assistance positioners 8 between pressing plate 2 and the load plate 1 and be used for fixing the positioner of electronic component with several, four auxiliary locators are arranged on four angles of pressing plate,
Positioner comprises screw thread guide wire 4, depression bar 6, built-in spring 9 and the part briquetting 7 that is connected between pressing plate 2 and the load plate 1.Auxiliary locator 8 supporting part briquettings 7 and a built-in spring 9, auxiliary locator 8 is arranged on the below of pressing plate 2, and part briquetting 7 and built-in spring 9 are connected in turn between auxiliary locator 8 and the load plate 1; Be fastened between pressing plate 2 and the load plate 1 to several screw thread guide wires 4 and depression bar 6 irregular alignments, screw thread guide wire 4 schedules on the pressing plate 2 through screw thread and nut locking, and the inwall of screw thread guide wire 4 is provided with guide hole, is with guiding cover 5 on the outer wall.
When need welding electronic component is set upright, only need to set upright pressing plate and be positioned on the load plate 1 of carrying through auxiliary locator 8 location, the both hands balance exert pressure downwards just can will make corresponding parts vertical fully be close to circuit board.Because of pressing plate can only move perpendicular to load plate after stressed, so electronic component can not cause skew, crookedly produce floating high, inclination because of stress point personnel gimmick and depression bar gap factor.
