Description

Technical Field

[0001] The utility model relates to the field of metal plate (aluminum plate, copper plate, steel plate, etc.) processing and manufacturing, in particular to a metal material purging and testing device. Background Art

[0002] Metal materials, especially metal sheets, are manufactured by rolling or casting, and the size of the produced sheets is determined by the size of the rolling mill rolls or the size of the crystallizer of the casting machine. Taking aluminum alloy sheets as an example, there are hot-rolled, cold-rolled, precision-cast sheets, etc. Among them, the precision-cast sheet is an aluminum flat ingot cast from a crystallizer, which is then cross-cut into several flat sheets after being heat-saturated and stress-relieved. The surface of the sheet is then milled to finally obtain a precision-cast aluminum alloy sheet with a mirror effect. This type of precision-cast sheet is often used in the fields of substrates for large electronic equipment and has high economic value.

[0003] After the milling of the precision casting plate is completed, it needs to be inspected manually to prevent the internal defects of metal casting on the plate surface, such as casting holes, sand holes, inclusions, etc., or bumps and scratches during processing or transportation. The above defects are all factors that determine the scrapping of precision casting plates. Therefore, during the manual inspection of the surface, it is necessary for the quality inspector to manually inspect one or both sides of the precision casting plate in detail. Before the manual inspection, due to the large amount of cutting oil, aluminum chips and impurities left on the plate surface during milling, the production staff needs to clean and purge the plate surface. Usually, the operator uses the high-pressure air in the factory to spray on the surface of the plate through a spray gun to blow away the cutting oil and aluminum chips. However, due to the large area of ​​the plate surface, first, the operator cannot reach the entire area of ​​the plate with a handheld spray gun, and needs to walk back and forth around the plate to purge, which is time-consuming and labor-intensive; secondly, due to the point-like spraying of the handheld spray gun, the cutting oil and other liquid impurities at the spray point will only be blown around other positions on the plate surface, and the cutting oil cannot be completely removed from the plate surface. Third, since some products are double-sided milled precision casting plates, both sides need to be purged and inspected. During the production process, the plate surface can only be turned over manually for purging and manual inspection, which is a complicated process and consumes a lot of manpower, material resources and time. Summary of the invention

[0004] The utility model provides a metal material purging inspection device, which can be used for cleaning the surface of metal materials, especially large-area precision casting plates, and can greatly improve the efficiency of purging the surface of workpieces, with excellent purging and cleaning effects. It can also realize automatic turning over of workpieces.

[0005] In order to achieve the above objectives, the technical solution of the utility model is as follows:

[0006] A metal material purging inspection device, a rotating shaft is arranged on the upper part of a frame, a turning frame is installed on the rotating shaft, step-shaped support beams are arranged at both ends of the turning frame, the upper plane of the low step of the support beam supports the edge of the precision casting plate, and rotating cylinders are arranged at both ends of the step-shaped support beam; the upper plane of the high step of the support beam supports and guides the two ends of the upper purge horizontal frame.

[0007] When the rotary cylinder is not clamped, its pressure head is swung out horizontally, which makes it convenient for the precision casting plate to be hoisted and placed from above. After clamping, the pressure head rotates 90 degrees to clamp and fix the precision casting plate on the turning frame.

[0008] The upper purge frame moves horizontally, and the jet array on the lower end of the frame sprays high-pressure air downward, which can achieve comprehensive purge of the entire plate surface. Different from the point-like spraying of traditional compressed air spray guns, the purge frame is a moving linear spraying area, which can blow out the cutting oil on the plate surface through the side. Therefore, not only the purge efficiency is greatly improved, but also the purge quality and effect are significantly improved.

[0009] An upper guide wheel groove is arranged on the upper plane of the high step of the step-shaped support beam, and a travel wheel is arranged at a matching position at the end of the upper purge cross frame, and the travel wheel is embedded in the upper guide wheel groove for travel.

[0010] The guiding function of the travel wheel and the upper guide wheel groove enables the upper purge cross frame to travel in a straight line on the top surface of the step-shaped support beam; in practice, limit mechanisms should also be set at both ends of the guide wheel groove to prevent the travel wheel from slipping out of the wheel groove.

[0011] A lower guide wheel groove is arranged on the lower plane of the high step of the step-shaped support beam, and a travel wheel is arranged at a matching position at the end of the lower purge cross frame, and the travel wheel is embedded in the lower guide wheel groove for travel.

[0012] The upper purge horizontal frame + the lower purge horizontal frame realize the simultaneous purge of the front and back sides of the precision casting plate, which is suitable for double-sided milling precision casting plate products. The double-sided purge can double the efficiency and ensure the purge quality.

[0013] A full-length rack track is arranged on the side of the step-shaped support beam, and the travel drive mechanism travels on the rack track. A travel wheel groove parallel to the rack track is also arranged on the side of the step-shaped support beam. Travel wheels are arranged at matching positions on the travel drive mechanism, and the travel wheels are embedded in the travel wheel grooves for travel. The travel drive mechanism is fixedly connected to the ends of the upper purge cross frame and the lower purge cross frame.

[0014] The travel drive mechanism includes a travel motor, a transmission gear and a travel gear meshed with a rack. The travel wheel groove can further limit the travel track and walking posture of the travel drive device, so that the travel gear and the rack always maintain a good meshing state; in practice, limit mechanisms should be set at both ends of the travel wheel groove and the rack to prevent the travel drive mechanism from escaping. The motor of the travel drive mechanism can realize forward and reverse rotation through the controller, so that the travel drive mechanism can reciprocate on the step-shaped support beam.

[0015] One end of the rotating shaft is connected to the flip driving mechanism, and the flip driving mechanism is installed on the frame. The flip driving mechanism includes a motor, a motor shaft is connected to a worm, a worm wheel is installed at the shaft end of the rotating shaft, and the worm gear is meshed and driven, so that the motor drives the flip frame to rotate; the motor adopts a brake motor, when the motor stops rotating, the flip frame remains stable and motionless, and the worm gear mechanism itself also has a self-locking function, and the braking and stopping ability is good.

[0016] Utility model advantages:

[0017] 1. The purge beam of the utility model can realize linear purge operation on the plate surface, changing the disadvantages of point-like purge of traditional purge guns. The purge area is large, the purge efficiency is greatly improved, and the purge quality and effect are better, saving manpower, material resources and time required for production, and improving production efficiency.

[0018] 2. The utility model is provided with purge beams on both the upper and lower surfaces, which can realize double-sided purge at the same time, and is suitable for the production and inspection of double-sided precision casting plates; and the purge beam has an automatic walking function, without the need for manual intervention, and the degree of automation is greatly improved; the walking motor program can be set to reciprocate for several times, and after the purge beam has been purged multiple times, the plate surface is cleaner.

[0019] 3. The utility model can realize the turning over or tilting of the precision casting plate, which is convenient for the inspectors to inspect the back of the plate surface without manual turning over, thus saving manpower.

[0020] 4. The utility model can be applied to the purging inspection operation of various metal material workpieces, and can be expanded to a wide range.
