Description

Detection and calibration integrated device for welding frame

Technical Field

The invention mainly relates to the field of automatic welding equipment, in particular to a detection and correction integrated device for a welding frame.

Background

In the existing production, a large frame piece needs to be welded, and the large frame piece is formed by welding a plurality of material parts. Because the heat and internal force generated in the welding process change, the formed product can be deformed greatly, so that detection, correction and model correction are required after the welding is finished. The traditional detection basically relies on measuring tools such as a manual holding tape measure, a caliper, an angle square and the like to measure welding joints one by one, marks after detecting places needing to be calibrated, and then carries out subsequent calibration operation. In the traditional correction, the weldment is cooled rapidly after being heated locally in a flame heating mode, so that the internal stress is changed. At present, the mode is dependent on manual operation skill requirements, has no universality and has the following technical problems:

Firstly, the working efficiency is low. During detection, the welding points of the large frame piece are more because the measuring tools such as a tape measure, a caliper and a square are needed to be manually held to measure the welding points one by one, so that the detection working efficiency is extremely low, and the development of the follow-up correction operation is seriously influenced. Meanwhile, during the calibration, the welding points to be calibrated are heated and calibrated one by means of a plurality of tools such as a flame gun, a calibration tool and the like, and then cooled in a water cooling mode and the like, so that the calibration efficiency is extremely low, and the follow-up operation is seriously influenced.

And secondly, the detection and the correction are not unified, and the accuracy is poor. Because the manual detection comparison depends on the skills and experience of quality inspection personnel, the operation methods, experience and the like of each manual detection have no uniformity, so that the detection results among different batches of frame piece products or among different welding spots of the same frame piece product have no uniformity, the detection accuracy is poor, the later correction precision is also influenced, and the quality and the strength of the product are finally influenced. Meanwhile, the existing correction method mostly has the purposes of locally heating a workpiece, then carrying out water cooling and the like to change the stress of the workpiece so as to deform the workpiece, and the method also depends on the operation skills and experience of workers, so that the operation method and experience of manual correction are not uniform at each time, the correction results among different batches of frame piece products or among different welding spots of the same frame piece product are not uniform, the correction accuracy is poor, and finally the quality and strength of the product are influenced.

Thirdly, labor intensity is high, and mistakes are easy to occur. Because of adopting manual detection and manual correction, the labor intensity of personnel is high; and because the welding points of the large frame part are more, the condition that a certain welding point forgets to detect or forgets to correct the shape, skips to detect or skips to correct the shape often occurs, and the quality and the strength of a product are seriously influenced.

Fourth, the degree of automation and intelligence is low. The detection and the correction are performed manually, and meanwhile, the manual feeding and the manual discharging are required before and after the detection and before and after the correction, so that the detection and the correction cannot be used together with other automatic equipment (such as an automatic feeding and discharging transmission equipment cannot be connected); meanwhile, integrated operation cannot be realized between detection and correction, and two different operation requirements lead to large operation occupation, cannot meet the operation requirements of high efficiency and automation, and cannot form automation and systemization operation.

Fifthly, the operation risk is high. The detection is performed manually, and the welding frame is heavy, so that the operation risk of collision and pressing is easy to occur. Meanwhile, during the correction, welding joints are heated and corrected one by means of a plurality of tools such as a flame gun, a correction tool and the like, and then cooled in a water cooling mode and the like, so that dangerous components such as high temperature, flame, cooling water vapor and the like exist on an operation site, misoperation danger of staff is easy to occur, and potential safety hazards exist on the site.

And secondly, the vertical roller supports and the transmission double gears are matched, so that the rollers can protrude upwards through the roller grooves respectively when lifted, and the transmission is effectively ensured.

The welding frame detection and correction integrated device forms excellent positioning coordination through more than two positioning blocks and more than two positioning driving assemblies capable of pushing the welding frame to translate, so that even if the welding frame transmitted each time moves in the transmission, descending and other processes, the welding frame can be positioned accurately before detection or correction; and the device is fixed during detection or correction, so that the position is not moved due to the pressing down of the detection mechanism, and the position is not moved due to the pressing down and the stretching of the correction.

Secondly, the detection tool frame has a detection function, and meanwhile, if a raised welding flaw part appears, the downward pressing detection fixture block can just press and shape the protrusion downwards, so that the purpose of correction is realized, namely, the detection tool frame disclosed by the application has the functions of detection and partial correction, the working content of the follow-up special correction is reduced, and the operation time is shortened.

Tenth, the detection and correction integrated device for the welding frame comprises a movable base, wherein the movable base is provided with a lateral correction device and a lifting correction device, namely, the device can realize lateral correction and also can realize correction in the up-down direction, can meet the correction requirements of different flaws of different welding spots, and has high correction efficiency and good correction effect.

Eleven is the detection and correction integrated device for the welding frame, which is provided by the invention, the adjusting seat is lifted up and down by rotating the screw rod assembly so as to adjust the up and down correction positions of the correction block.

As shown in fig. 1 to 8, the invention provides a detection and calibration integrated device for a welding frame, which comprises a frame platform 2 for being in butt joint with an external transmission mechanism, wherein the frame platform 2 is provided with a platform plate, and the height of the frame platform 2 is between 0.2 meters and 2 meters. A liftable roller transmission mechanism 3 is arranged below the frame platform 2, and is used for continuously transmitting the welding frame 1 transmitted by the external transmission mechanism to the frame platform 2 after lifting, and enabling the welding frame 1 to fall on the frame platform 2 after descending; the frame platform 2 is provided with a positioning and fixing mechanism 4 and a liftable detection mechanism 5, wherein the positioning and fixing mechanism 4 is used for adjusting and fixing the position of the welding frame 1 after being placed, and the detection mechanism 5 is lowered and pressed on the welding frame 1 to carry out detection operation; the frame platform 2 is also provided with more than one movable calibration mechanism 6 for calibrating the welding frame 1, and the movable calibration mechanism 6 can transversely move on the side edge of the frame platform 2 along the transmission direction of the frame platform 2 so as to be used for calibrating the welding frame 1 after detection at different positions. The specific implementation is as follows:

the front end and the rear end of the frame platform 2 can be directly butted with an external transmission mechanism (such as a roller transmission belt and the like as shown in the figure B) to automatically feed and discharge. In operation, the roller transmission mechanism 3 below the frame platform 2 is lifted and enters a rolling transmission state, and forms transmission butt joint with the external transmission mechanism at the front end. The welding frame 1 transferred from the external transfer mechanism is then further transferred to the rack platform 2. At this time, the roller transfer mechanism 3 stops transferring and descends so that the welding frame 1 originally carried on the roller transfer mechanism 3 falls on the rack platform 2. At this time, the positioning and fixing mechanism 4 starts the operation, and adjusts and fixes the position of the welding frame 1 after being dropped. That is, the welding frame 1 is positioned before being inspected, so as to ensure the accurate operation of the subsequent inspection mechanism 5. After positioning and fixing, the detection mechanism 5 descends and is pressed on the welding frame 1, detection operation is carried out through the detection mechanism 5, which welding positions have problems and follow-up correction operation is needed, meanwhile, the detection mechanism 5 ascends and withdraws to the original position, and when the positioning and fixing mechanism 4 still enables the welding frame 1 to be positioned and fixed. Then, the movable calibration mechanism 6 starts to move transversely for performing calibration operations at different positions on the fixed welding frame 1 according to the detection result. In this embodiment, a movable calibration mechanism 6 is mounted on both sides of the frame platform 2, so that efficient calibration can be performed from both sides at the same time. After the correction is finished, the positioning and fixing mechanism 4 can loosen the welding frame 1, and enable the roller transmission mechanism 3 below the frame platform 2 to be lifted to support the welding frame 1, then the roller transmission mechanism 3 enters a rolling transmission state again, and the welding frame 1 after the correction is continuously transmitted to an external transmission mechanism at the rear end, so that automatic feeding, detecting, correction and falling operations are formed. Through the special scientific design, the method has the following advantages:

The integrated device for detecting and calibrating the welding frame is high in integration level, the frame platform 2, the roller transmission mechanism 3, the positioning and fixing mechanism 4, the liftable detection mechanism 5 and the movable calibration mechanism 6 capable of transversely moving are matched and mutually supported, a series of actions of automatic feeding and discharging, automatic positioning, automatic fixing, automatic detection and automatic calibration can be formed, a plurality of measuring tools such as a tape measure, a caliper and an angle square are not needed to be manually held for measuring welding points one by one, a plurality of tools such as a flame gun are not needed to be manually held for calibrating the welding points one by one, detection and calibration work efficiency is greatly improved, and efficient follow-up operation is effectively ensured. Meanwhile, the high integration level effectively reduces the field use area of the equipment, and greatly reduces the operation area requirement on a factory building.

Secondly, the detection and correction integrated device for the welding frame has uniformity and high accuracy in detection and correction. Because the accurate location of position has been realized through location fixed establishment 4, the rethread detection mechanism 5 realizes that push down once promptly accurately detects the state of all welding points, and rethread removes the correction mechanism 6 and unifies and carry out the correction, has reduced the dependence to quality inspection personnel's skill and experience for the detection and correction between the frame spare product of different batches, or between the different welding points of same frame spare product all have unification, check and correction precision is high, has finally improved the quality and the intensity of product.
