Description

Technical Field

[0001] This invention relates to the field of automotive parts processing equipment technology, and in particular to a precision detection device for calibrating the rotating platform of the top mold table in a casting production line. Background Technology

[0002] Castings account for a large proportion of automotive parts. During the production of castings, the rotating platform used for changing molds needs to rotate frequently and is not rigidly connected to the sand box and top mold table. After a period of use, the amount of mold misalignment between the rotating platform and the sand box and top mold table increases, which easily leads to mold misalignment. This not only reduces the machining accuracy, but also takes a long time for maintenance and debugging, thereby reducing production efficiency.

[0003] The current practice is to periodically check the position of the rotating platform by hand, and to use handheld gauges and handheld pry bars for adjustment. Due to the small space inside the equipment and the inconvenience of operation, this method not only results in a large workload for workers and low efficiency, but also generally low accuracy. Summary of the Invention

[0004] The present invention aims to address the shortcomings of the prior art by providing a precision detection device for calibrating the rotating platform of the top mold table in a casting production line.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precision testing device for calibrating the rotating platform of a casting production line's top mold table includes a horizontal cylinder. Telescopic rails are provided on both sides of the horizontal cylinder, and the rails are arranged parallel to the cylinder. The cylinder body and the telescopic rails are both fixedly connected to the inner wall of the casting equipment's housing. A gauge is provided on the telescopic rails, and the gauge includes a support plate located below the sand box and above the top mold table. The bottom ends of the support plate are slidably connected to the two telescopic rails respectively. A locking block is fixed to the end of the horizontal cylinder's piston rod, and a locking groove is provided on the top of the support plate to cooperate with the locking block.

[0007] The support plate is equipped with two CCD cameras at the top and bottom for data acquisition of the top mold table and sand box. It also has at least one non-contact displacement sensor at both the top and bottom. Both the CCD cameras and the non-contact displacement sensors are electrically connected to the control system of the casting production line. The bottom of the support plate has two pairs of legs arranged in a figure-eight pattern. One leg in each pair has a positioning block at its bottom, which mates with a positioning hole on the top of the top mold table.

[0008] The rotating platform used for changing molds has several segmented positioning columns on its inner side. The bottom of the support plate is equipped with segmented positioning holes that cooperate with the segmented positioning columns. The bottom of the top mold table is equipped with a lifting mechanism for driving the top mold table to rise and fall.

[0009] Preferably, the lifting mechanism includes a connecting plate, which is fixedly connected to the bottom of the top mold table, and a vertical cylinder is fixedly installed at the bottom of the connecting plate. The bottom of the vertical cylinder is fixedly connected to the bottom of the casting equipment housing.

[0010] Preferably, the telescopic track is driven by an electric telescopic rod.

[0011] Preferably, the telescopic track is slidably connected to the support plate via several rollers.

[0012] Preferably, the positioning block is cylindrical and has a chamfer on the bottom edge to facilitate entry into the positioning hole.

[0013] Preferably, the slot includes two vertical limiting plates. When the slot is engaged with the locking block of the horizontal cylinder, the locking block is located between the two vertical limiting plates. The vertical limiting plate on the side closer to the horizontal cylinder is provided with a U-shaped groove to facilitate the horizontal cylinder piston rod to pass through, enter, and move out.

[0014] The beneficial effects of this invention are: by using a CCD camera to collect data from the top mold stage twice, the data is used as the basis for adjusting the mold misalignment of the rotating platform. This method not only reduces the workload of workers and improves the efficiency of inspection and adjustment, but also improves the accuracy of inspection and adjustment, thereby increasing the yield rate.

[0020] The following will describe in detail, with reference to the accompanying drawings, embodiments of the present invention. Detailed Implementation

[0021] The present invention will be further described below with reference to embodiments:

[0022] A precision testing device for calibrating the rotating platform of a casting production line top mold table includes a horizontal cylinder 1. Telescopic rails 2 are provided on both sides of the horizontal cylinder 1, and the telescopic rails 2 are arranged parallel to the horizontal cylinder 1. The cylinder body of the horizontal cylinder 1 and the telescopic rails 2 are both fixedly connected to the inner wall of the casting equipment housing. A gauge is provided on the telescopic rails 2, and the gauge includes a support plate 3. The support plate 3 is located below the sand box 15 and above the top mold table 12. The bottom ends of the support plate 3 are slidably connected to the two telescopic rails 2 respectively. A locking block 5 is fixedly provided at the end of the piston rod of the horizontal cylinder 1, and a locking groove 4 is provided on the top of the support plate 3 to cooperate with the locking block 5.

[0023] The support plate 3 has two CCD cameras 6 at its top and bottom for data acquisition of the top mold table 12 and sand box 15. The support plate 3 also has at least one non-contact displacement sensor 7 at its top and bottom. Both the CCD cameras 6 and the non-contact displacement sensors 7 are electrically connected to the control system of the casting production line. The bottom of the support plate 3 has two pairs of legs 8 arranged in a figure-eight shape. One leg 8 in each pair has a positioning block 9 at its bottom, which engages with the positioning hole on the top of the top mold table 12.

[0024] The rotating platform 11 used for changing molds has several segmented positioning columns 10 on its inner side. The bottom of the support plate 3 is provided with segmented positioning holes that cooperate with the segmented positioning columns 10. The bottom of the top mold table 12 is provided with a lifting mechanism for driving the top mold table 12 to rise and fall.

[0025] Preferably, the lifting mechanism includes a connecting plate 13, which is fixedly connected to the bottom of the top mold table 12. A vertical cylinder 14 is fixedly installed at the bottom of the connecting plate 13, and the bottom of the vertical cylinder 14 is fixedly connected to the bottom of the casting equipment housing.

[0026] Preferably, the telescopic track 2 is driven by an electric telescopic rod.

[0027] Preferably, the telescopic track 2 is slidably connected to the support plate 3 via several rollers.

[0028] Preferably, the positioning block 9 is cylindrical and has a chamfer on the bottom edge to facilitate entry into the positioning hole.

[0029] Preferably, the slot 4 includes two vertical limiting plates. When the slot 4 is engaged with the locking block 5 of the horizontal cylinder 1, the locking block 5 is located between the two vertical limiting plates. The vertical limiting plate on the side closer to the horizontal cylinder 1 is provided with a U-shaped groove that facilitates the piston rod of the horizontal cylinder 1 to pass through, enter, and move out.

[0030] When this invention is used, the horizontal cylinder 1 and the telescopic rail 2 extend simultaneously, moving the inspection tool directly above the top mold platform 12. The vertical cylinder 14 pushes out, causing the top mold platform 12 to move upward until the two positioning blocks 9 are inserted into the positioning holes at the top of the top mold platform 12. The telescopic rail 2 retracts, causing it to lose its supporting function on the support plate 3. The vertical cylinder 14 retracts a certain distance, causing the locking block 5 of the horizontal cylinder 1 to disengage from the locking groove 4, and the horizontal cylinder 1 retracts.

[0031] The vertical cylinder 14 is ejected to the designated position. The control system of the casting production line controls the ejection height of the vertical cylinder 14 through the non-contact displacement sensor 7 located on the top of the support plate 3 to maintain a suitable distance from the sand box 15 above. The CCD camera 6 located at the top collects data from the two guide sleeves of the sand box 15, and the CCD camera 6 located at the bottom collects data from the two guide sleeves of the top mold table 12. The collected data is transmitted to the CCD imaging module of the control system of the casting production line for storage.

[0032] The vertical cylinder 14 retracts, causing the fixture to descend. When the fixture descends to the height of the rotating platform 11, the first segment of the segmented positioning column 10 initially positions the fixture. The top mold table 12 continues to descend until it reaches the designated height. The control system of the casting production line controls the retraction height of the vertical cylinder 14 through the non-contact displacement sensor 7 located at the bottom of the support plate 3 to maintain a suitable distance between the fixture and the top mold table 12 below. After the fixture is removed from the top mold table 12, the segmented positioning column 10 and the segmented positioning hole on the support plate 3 are fully engaged and positioned. At this time, the CCD camera 6 located at the bottom of the support plate 3 collects data from the two guide sleeves of the top mold table 12 again and transmits the collected data to the CCD imaging module of the control system of the casting production line for comparison with the previous collected data. This allows the calculation of the misalignment between the rotating platform 11, the top mold table 12, and the sand box 15. The control system of the casting production line can then correct the misalignment of the rotating platform 11 by using a hydraulically driven adjustment mechanism based on the calculation results.

[0033] After adjustment, the horizontal cylinder 1 extends, positioning the locking block 5 directly above the slot 4. The vertical cylinder 14 extends and lifts the fixture, disengaging it from the rotating platform 11, until the locking block 5 engages in the slot 4. The telescopic rail 2 extends to support the support plate 3 again. The vertical cylinder 14 retracts, resetting the top mold platform 12. Simultaneously, the horizontal cylinder 1 and the telescopic rail 2 retract, resetting the fixture. The inspection and adjustment are now complete. This method not only reduces worker workload and improves inspection and adjustment efficiency but also enhances the accuracy of inspection and adjustment, increasing the yield rate.
