Further improvement as above-mentioned technical proposal:
The clamping device that board positioning mechanism includes base and is installed on base of marking time, the clamping device include clamping and driven Moving part and clamping briquetting, the clamping briquetting is installed in the output end of clamping actuator, and is pushed in the driving of clamping actuator The tight or relieving step plate.
The board positioning mechanism of marking time also includes the position-limit mechanism being installed on base, and the position-limit mechanism includes spacing drive Moving part and spacer pin, the spacer pin are installed in the output end of spacing actuator, and stretch under the driving of spacing actuator or The positioning hole exited on the step plate.
The base includes slide, slide unit and slide unit actuator, and the slide is fixed on pedestal, and the slide unit passes through straight Line guide rail is slidedly arranged on slide, and the output end of the slide unit actuator is connected with slide unit, and the clamping device and position-limit mechanism are equal It is installed on the slide unit.
Compared with prior art, the advantage of the invention is that:
The chip main chord welding positioning tool of the present invention, is equiped with step plate positioning on pedestal by each rolling support device Mechanism, for being positioned to the step plate of chip main chord, compared to traditional step plate line erection method, the present invention spells Dress operation is easier, and positioning precision is high, and can ensure that the step plate position dimension of each chip main chord is unified, is positioned in step plate In the presence of mechanism, step plate keeps effective fixed in welding process, is shunk so as to reduce welding to step plate positional precision Influence, finally make the assembling of chip main chord easier, quick;Board positioning mechanism of marking time is arranged on by rolling support device Side, when board positioning mechanism of marking time drive step plate and chip main chord against when, chip main chord is at the contact point due to having The support of rolling support device, so as to be less prone to deformation, make the welding positioning precision of step plate and chip main chord higher.

Embodiment
As depicted in figs. 1 and 2, the chip main chord welding positioning tool of the present embodiment, including the positioning of pedestal 1, fish platee Mechanism 2, end jacking mechanism 3, primary nip mechanism 4 and two pieces rolling support device 5, fish tail board positioning mechanism 2 and end are held out against Mechanism 3 is divided into the both ends of pedestal 1, and primary nip mechanism 4 is divided into main clamping machine located at the middle part of pedestal 1, two pieces rolling support device 5 The both sides of structure 4, it is equiped with by each rolling support device 5 on pedestal 1 and is stepped on for what is positioned to the step plate of chip main chord Walk board positioning mechanism 6.The chip main chord welding positioning tool of the present invention, is installed on pedestal 1 in each side of rolling support device 5 Mark time board positioning mechanism 6, for being positioned to the step plate of chip main chord, rule compared to traditional step plate assembled Mode, the assembled operation of the present embodiment is easier, and positioning precision is high, and can ensure that the step plate position dimension system of each chip main chord One, in the presence of board positioning mechanism 6 of marking time, step plate keeps effective fixed in welding process, is shunk so as to reduce welding Influence to step plate positional precision, finally make the assembling of chip main chord easier, quick;Board positioning mechanism 6 of marking time is set On the side of rolling support device 5, when board positioning mechanism 6 of marking time drive step plate and chip main chord against when, chip main chord Due to there is the support of rolling support device 5 at the contact point, so as to be less prone to deformation, make step plate and chip main chord It is higher to weld positioning precision.
In the present embodiment, board positioning mechanism 6 of marking time includes base 63 and the clamping device 61 being installed on base 63, clamping Mechanism 61 includes clamping actuator 611 and clamping briquetting 612, and clamping briquetting 612 is installed in the output end of clamping actuator 611, And compressed under the driving of clamping actuator 611 or decontrol step plate, when needing to position step plate and welded, clamping Briquetting 612 compresses step plate under the driving of clamping actuator 611, and after the welding to step plate is completed, clamping briquetting 612 exists Clamp and decontrol step plate under the driving of actuator 611.
In the present embodiment, board positioning mechanism 6 of marking time also includes the position-limit mechanism 62 being installed on base 63, position-limit mechanism 62 Including spacing actuator 621 and spacer pin 622, spacer pin 622 is installed in the output end of spacing actuator 621, and in spacing drive The positioning hole for being stretched into or exiting on step plate under the driving of moving part 621, it is spacing when needing to position step plate and welded Pin 622 stretches into the positioning hole on step plate under the driving of spacing actuator 621, spacing after the welding to step plate is completed Pin 622 exits the positioning hole on step plate under the driving of spacing actuator 621.
In the present embodiment, base 63 includes slide 631, slide unit 632 and slide unit actuator 633, and slide 631 is fixed on pedestal On 1, slide unit 632 is slidedly arranged on slide 631 by line slideway, and the output end of slide unit actuator 633 is connected with slide unit 632, folder Hold mechanism 61 and position-limit mechanism 62 is assembled on slide unit 632.When clamping device 61 and position-limit mechanism 62 are completed to marking time jointly After the positioning of plate, slide unit 632 moves integrally under the driving of slide unit actuator 633 and close to chip main chord, when completion is to stepping on After the welding for walking plate, clamping device 61 decontrols step plate, the positioning hole that position-limit mechanism 62 is exited on step plate, the He of clamping device 61 Position-limit mechanism 62 completely disengages with step plate, and now the driving lower slide unit 632 in slide unit actuator 633 moves integrally and away from piece Formula main chord, so that chip main chord is deviate from from the chip main chord welding positioning tool of the present invention.
