Conventional processing methods can only process single parts in each process, which takes a long time and has low work efficiency.

[0003] Due to the irregular shape of the continuous casting roll bearing housing, it is difficult to select the lathe reference surface, the milling machine process reference surface, and stack them; the lathe processing clamping is to use a four-jaw chuck to clamp the outer shape of the bearing housing, and the outer shape is the rough surface. Each time the bearing housing is processed, the jaws need to be calibrated, which is troublesome and time-consuming, and the efficiency is low; when milling the bottom surface and the lower stop, the work efficiency of single milling is very low, and there are many idle strokes of the milling cutter. Each time the bearing housing is processed, the tool setting position of the milling cutter also needs to be adjusted, and the calibration and processing operations are troublesome and time-consuming, and the efficiency is low; when drilling the inclined hole on the bottom surface of the bearing housing, due to the inability to position the drill bit, the inaccurate placement of the bearing housing leads to a large drilling deviation, and it is necessary to first mill the drill bit drilling plane on the milling machine before drilling; when processing the inclined hole on the bottom surface and the end face screw hole of the bearing housing, a special drill jig tooling also needs to be designed.

[0004] The invention patent with the publication number of CN102152075A discloses a processing method for a continuous casting machine bearing housing on August 17, 2011, which includes: after rough milling the blank, rough turning the inner hole, milling the water cooling groove, and drilling the water hole of the bearing housing body in sequence, removing and grinding the burrs of the water tank and the water hole, then sending it into a high-temperature furnace for heating for 4 hours, and keeping the temperature of the bearing housing body at 120-150°C, and finally entering the welding process; welding process: using manual argon arc welding to seal and weld the stainless steel cover plate, and then heat preservation; the front and rear planes of the bearing housing body are precisely ground to the drawing size on a grinding machine, and then the bottom surface of the bearing housing body is ground with the rear plane as the reference through a fixture, and the perpendicularity between the front and rear planes and the bottom surface is controlled within the range of ±0.05 mm; using wire cutting processing method to process the key groove on the bottom surface, and then using the bottom surface key groove as the reference, controlling the center height and symmetry through a fixture, and leaving a margin after semi-finishing turning; finally, precisely turning the inner hole of the bearing seat body to the drawing size. This processing method for the continuous casting machine bearing housing cannot solve the above-mentioned technical problems either. Summary of the Invention

[0039] The following is a further detailed description of the specific embodiments of the present invention with reference to the accompanying drawings through the description of the embodiments, aiming to help those skilled in the art have a more complete, accurate and in-depth understanding of the inventive concept and technical solution of the present invention and facilitate its implementation.

[0040] The batch processing method of the continuous casting roll bearing housing includes the following steps:

[0041] Step S1, draw the contour line for rough turning;

[0042] Step S2, rough turn the inner hole 20 and the end face 22 of the bearing housing;

[0043] Step S3, assemble the bearing housing through a series of toolings, and mill the bottom plane and the lower stop 2 of the bearing housing;

[0044] Step S4, mill the bottom surface holes of the bearing housing with a CNC milling machine;

[0045] Step S5, clamp the bearing housing through a lathe tooling, and finish turn the inner hole 20 and the end face 22 of the bearing housing;

[0046] Step S6, clamp the bearing housing through a drill press tooling, and machine the end face holes and the bottom surface oblique holes;

[0047] Step S7: The fitter taps the screw holes and welds the side plates of the water channel 19.

[0048] Step S8: Conduct a hydrostatic pressure test and conduct a final inspection of the product.

[0049] As Figures 1 - 3 shown, in step S3, the following steps are included: S3-1: Set two relatively arranged bearing seats as a group, and install the support cylinder 3 in the inner hole 20 of each group of bearing seats; S3-2: Place each group of bearing seats coaxially in sequence; S3-3: Pass the mandrel 4 through the bearing seat and the support cylinder 3 in sequence; S3-4: Weld the square steel 5 on both sides of the bearing seat. The bearing seats are arranged alternately, and the side with the larger opening end size is set to be in contact as a group. Install the support cylinder 3 in the inner hole 20 of each group of bearing seats, and form a supporting effect inside the bearing seat, further improving the overall stability of multiple bearing seats, creating batch positioning conditions for milling processing. The mandrel 4 can not only connect the bearing seats in series as a whole, but its axis is coaxial with the axis of the inner hole 20 of the bearing seat, providing a positioning reference for the milling machine process, realizing batch processing of the milling machine, reducing processing errors, and ensuring that the quality of the same batch of products is uniformly qualified. The square steel 5 plays a role in further reinforcement.

[0050] As Figures 4 - 6 shown, in step S5, the following steps are included: S5-1: Disassemble the series connection tooling; S5-2: Locate the lower stop 2 of the bearing seat through the support 7; S5-3: Axially position the bearing seat through the leveling screw 10; S5-4: Tighten the compression bolt 9 to compress the outside of the bearing seat. The four-jaw chuck is calibrated accurately when machining the first-piece bearing seat, and the product accuracy requirements are met after machining the bearing seat. After that, every time as long as the bearing seat is installed on the lathe, there is no need to adjust the lathe chuck, and only need to tighten the product fixing bolts on the lathe tooling, which greatly improves the work efficiency of the bearing seat lathe process.

[0051] As Figures 7 - 9 shown, in step S6, the following steps are included: S6-1: Locate the lower stop 2 of the bearing seat through the positioning platform 12; S6-2: Tighten the compression screw 15 to compress the bearing seat; S6-3: Drill holes after installing the straight-hole drill bushing 17 and the inclined-hole drill bushing 18.

[0052] As Figure 1 shown, the outer diameter of the support cylinder 3 is matched with the inner hole 20 of the bearing seat, and the inner diameter of the support cylinder 3 is matched with the mandrel 4; the support cylinder 3 is shorter than the sum of the lengths of the inner holes 20 of the two bearing seats. The outer diameter of the support cylinder 3 is matched with the inner hole 20 of the bearing seat, realizing connecting a pair of bearing seats as a whole, playing a limiting and restraining effect. At the same time, the inner diameter of the support cylinder 3 is matched with the mandrel 4, forming a limiting and restraining effect on all the series-connected bearing seats. The stability is reliable, so that the machining position of the bearing seat will not be distorted or displaced relative to each other, and further ensures the milling dimension accuracy.

[0053] As Figures 1 - 3 shown, the series tooling includes a mandrel 4, a support cylinder 3 and a square steel 5. The mandrel 4 is horizontally arranged. The support cylinder 3 is arranged in the inner hole 20 of the bearing seat. The mandrel 4 penetrates through the bearing seat and the support cylinder 3. The square steel 5 is welded and fixed outside the bearing seat. In the series tooling, since the inner hole 20 of the bearing seat has not undergone the finish turning process, the setting of the support cylinder 3 will not affect the forming accuracy of the inner hole 20. There are four square steels 5. Two square steels 5 are welded on each side outside the bearing seat, further improving the fixing effect of the series bearing seats.

[0054] As Figures 4 - 6 shown, the lathe tooling includes a first steel plate 6. A support 7 is provided at the bottom end of the first steel plate 6. A plurality of pressing seats 8 are provided on the first steel plate 6. A pressing bolt 9 is threadedly connected to the pressing seat 8. The end of the pressing bolt 9 extends out of the pressing seat 8. A leveling screw 10 is threadedly connected to the first steel plate 6. The leveling screw 10 is horizontally arranged. The use of the pressing bolt 9 has a fastening effect on the bearing seat and can also adapt to the irregular outer shape structure of the bearing seat. The use of the leveling screw 10 positions the bearing seat front and back. For the same batch of bearing seats, after only positioning its lower stop 2, there is no need to level again. Just use the pressing bolt 9 to press the bearing seat to ensure the positioning accuracy and guarantee the processing quality. Among them, the support 7 is installed on the steel plate in a detachable manner, and the two are positioned by a flat key.

[0055] As Figures 7 - 9 shown, the drill press tooling includes a second steel plate 11. A positioning platform 12 is provided in the middle of the second steel plate 11. A limiting plate 13 and a mounting plate 14 are respectively provided on both sides of the second steel plate 11. A pressing bolt 9 is threadedly connected to the mounting plate 14. The end of the pressing bolt 9 extends out of the mounting plate 14. The positioning platform also forms a positioning for the lower stop 2 of the bearing seat. The pressing bolts 9 on the limiting plate 13 and the mounting plate 14 form a front and back positioning for the bearing seat, thereby ensuring the processing accuracy of drilling.

[0056] In step S1, a finish machining allowance of 3 mm is reserved for the contour line. The contour line is marked during rough turning, and a 3-mm machining allowance is left for finish turning, reducing the requirements for product alignment and machining operation accuracy in the next process.

[0057] When machining the bottom surface of the bearing housing and the lower locating collar 2, to achieve batch processing, the key is to have a reliable machining reference surface. Add a rough machining process for the blank before the milling process. Rough machine the inner hole 20 and the end face 22 of the bearing housing. After stringing the bearing housings together with the inner hole 20 of the bearing housing as the reference, then mill the bottom surface of the bearing housing and the lower locating collar 2 as a whole. By selecting the lower locating collar 2 of the bearing housing as the positioning reference, design a positioning fixture for the lower locating collar 2 and fix it on the lathe. By operating in this way, the complex steps of scribing and lathe calibration are omitted. Each time, directly place the bearing housing on the fixture and fix it to ensure accurate position. Direct machining can ensure product accuracy and greatly improve the lathe efficiency; when drilling the inclined hole on the bottom surface of the bearing housing, use a drill jig fixture, and use the drill bushing of the drill jig to guide the drill bit to ensure that the inclined hole does not deviate.

[0058] The processing procedures are: scribing → rough turning → assembling the bearing housings with a series connection fixture → milling the bottom plane and the lower locating collar 2 on a CNC milling machine → milling the bottom hole of the bearing housing on a CNC milling machine → clamping the bearing housing with a lathe fixture to machine the inner hole 20 and the end face 22 → machining the end face hole and the bottom inclined hole with a drill press fixture → tapping the screw hole by a fitter → welding the water channel 19 steel plate → hydrostatic test → final inspection of the product.

[0059] The specific steps are as follows:

[0060] Step 1: Scribe and rough machine the inner hole 20 and the end face 22 of the bearing housing.

[0061] Scribe the rough turning contour line.

[0062] Rough machine the inner hole 20, leaving a 3-mm finishing allowance on each side. Rough machine the two side end faces 22, leaving a 3-mm machining allowance on each side. Since the contour line is scribed during rough machining and a 3-mm machining allowance is left for finish turning, the calibration and machining accuracy requirements for all products are not very high, and the machining efficiency and difficulty are not much affected.

[0063] Step 2: Use a series connection fixture to string 8 - 10 bearing housings into one body, ensuring that the reference of the inner hole 20 is consistent and firm and reliable;

[0064] Series connection operation steps:

[0065] 1. Insert the mandrel 4 into the bearing housing and the support cylinder 3 in sequence;

[0066] 2. The structure of the support cylinder 3 is that its outer diameter fits with the inner hole 20 of the bearing housing, and its inner hole 20 fits with the mandrel 4;

[0067] 3. The length of the support cylinder 3 is longer than the length of the inner hole 20 of a single bearing housing and slightly shorter than the length of the inner holes 20 of a pair of bearing housings, so that a pair of bearing housings can sleeve the support cylinder 3. After inserting the mandrel 4 into the support cylinder 3, the reference of each bearing housing can be kept consistent;

[0068] Among them, the number of assembled bearing seats can be determined according to the size of the bearing seat and the processing length of the processing milling machine. After all are assembled as shown in the figure, 4 square steels 5 are welded on both sides of the bearing seat, so that after all the bearing seats are assembled, they are connected into a whole, and the position will not be distorted or displaced relative to each other.

[0069] Step 3: Place the strung bearing seats on the CNC milling machine, use the mandrel 4 as the positioning reference for positioning, and machine the lower counterbore 2; this method can not only ensure the machining accuracy of machining the lower counterbore 2, but also greatly improve the machining efficiency.

[0070] Taking the width of the lower counterbore of the bearing seat as 170 mm and the thickness as 95 mm as an example, using a milling cutter head with a diameter of 80 mm, the milling cutter path for machining a single bearing seat is (80 + 95) mm * 3 = 525 mm. If 8 bearing seats are strung together, its milling cutter path is (110 * 8) mm * 3 = 2640 mm. After being strung, the milling cutter path per single bearing seat is 2640 mm / 8 = 330 mm, which is about 1.6 times higher than the original machining efficiency. (Note: The machining thickness of the bottom surface of the bearing seat is 95 mm, and the total thickness including the protruding part at the tail is 110 mm.)

[0071] Step 4: Disassemble the bearing seats from the series connection fixture.

[0072] Step 5: Place the bearing seats on the lathe, and use the lathe fixture for positioning and clamping.

[0073] Precision turning positioning operation steps:

[0074] 1. Use the lower counterbore 2 support 7 to position the bearing seat 1, which can ensure the accuracy of the center height and left - right alignment.

[0075] 2. Use three leveling screws 10 to adjust the fixed position, which can ensure the flatness of the bearing seat and the front - rear positioning of the bearing seat.

[0076] Step 6: Place the bearing seats in the drilling process, and use a special drilling fixture for drilling.

[0077] Drilling positioning operation steps:

[0078] 1. Use the counterbore of the steel plate to position with the counterbore of the bearing seat;

[0079] 2. After tightening the compression screw 15, the bearing seat can be fixed to the drilling fixture to prevent loosening;

[0080] 3. Straight hole drill sleeves 17 and inclined hole drill sleeves 18 are installed in each hole, and the drilling positions are set according to the processing requirements.

[0081] When drilling an inclined hole, the bearing housing needs to be adjusted to the position consistent with the inclined hole before drilling. Since the drill bit hole of the drilling die has a guiding function, and the drill bushing adopts a quenching process and has extremely high hardness, it can guide the drill bit to meet the processing requirements and improve the drilling efficiency. For drilling the end face hole, a similar drilling tooling as above is also used, embedding the end face hole, installing the drill bit and drill bushing to meet the drilling requirements.

[0082] Step Seven: Weld the side plate of the bearing housing.

[0083] Step Eight: Tap the bearing housing.

[0084] Step Nine: Conduct a hydrostatic test on the bearing housing.

[0085] The batch processing method of this continuous casting roll bearing housing realizes the combined use with the series tooling by adding a rough turning process in the front production process of the bearing housing. It not only achieves the purpose of batch milling processing, greatly improves the production efficiency, but also has the effect of pre-guaranteeing the dimensional accuracy of the lower stop 2 of the bearing housing, enabling the bearing housing to use its own lower stop 2 as the positioning reference, solving the problems of the selection of the machining reference surface and the stacking difficulty of the bearing housing in the current technology, ensuring the dimensional accuracy and machining quality of the milling, turning, drilling and other processes in the subsequent processes, and combining the use of the lathe tooling and the drilling tooling, saving the steps of adjusting the jaws, eliminating the positioning deviation caused by inaccurate placement in the subsequent processes, with convenient operation steps and effectively improving the production efficiency; the series tooling is reasonably designed. By using the mandrel 4, the support cylinder 3 and the square steel 5, a reliable positioning of multiple support seats is formed, ensuring its stability during the milling process and meeting the purpose of batch processing.

[0086] The present invention has been described exemplarily in combination with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited by the above methods. As long as various non-substantive improvements are made by adopting the method concept and technical solution of the present invention; or without improvement, the above concept and technical solution of the present invention are directly applied to other occasions, they are all within the protection scope of the present invention.
