Description

Technical Field

[0001] This invention relates to the field of glass processing technology, and in particular to a traction roller concentricity compensation device and compensation method. Background Technology

[0002] In glass processing, the traction rollers play a crucial role in guiding the glass within the furnace, directly impacting the quality of the glass substrate and significantly affecting product quality aspects such as warpage, bow, and height. Because the roller shaft is repeatedly used in high-temperature environments, various operating conditions lead to shaft deformation. The amount of deformation determines the runout of the boss in the coating material after processing. Therefore, roller core deformation directly affects the concentricity error between the two bearing seats and the boss. The concentricity of the roller core and the boss directly affects the amount of floating after the glass is clamped by the traction rollers on the machine. Currently, conventional processing methods result in boss runout of approximately 0.1-0.15mm, with a floating amount of approximately 0.3mm after roller core pairing on the machine.

[0003] Currently, during the processing of traction rollers, the runout of the roller core support position is checked through the bearing housing. Only when the runout is within the specified requirements can the runout of the tooling inspection boss on the short roller after processing be guaranteed to meet the design requirements. Since the conventional center support is fixed on the machine bed, if the runout of the roller core at the corresponding support position exceeds the tolerance, the operator will check and mark the qualified position and adjust the center support position accordingly. However, constantly moving the center support position is not conducive to improving work efficiency.

[0004] Therefore, in order to ensure the pass rate of traction short roll processing and further improve the coaxiality accuracy, a processing device to overcome roll core deformation was designed to meet the processing difficulty caused by roll core deformation, reduce the number of roll core corrections, and reduce the workload of operators repeatedly inspecting the roll core. Summary of the Invention

[0005] To address the technical problems existing in the background art, the present invention proposes a traction roller concentricity compensation device and compensation method.

[0006] The present invention proposes a method for compensating for the concentricity of traction rollers, comprising the following steps:

[0007] S1. Measure the runout of the roller core;

[0008] S2. Clamp one end of the bushing with a chuck and support the middle of the bushing with a central bracket so that the bushing is set parallel to the axis of the bearing seat.

[0009] S3. Pass the end of the roller core away from the short roller through the bushing so that the annular support part of the roller core corresponds to the end of the bushing away from the chuck.

[0010] S4. Adjust the position of the annular support relative to the end of the roller core away from the chuck based on the runout obtained in S1, so as to compensate for the runout.

[0011] Preferably, in S1, the measurement of the runout of the roller core is specifically performed by: horizontally mounting the roller core of the traction roller on the bearing seat, rotating the roller core, setting a distance measuring instrument on the side of the roller core near the short roller, and measuring the distance between at least three points on the annular support portion of the roller core near the short roller end using the distance measuring instrument to obtain the runout of the roller core.

[0012] Preferably, in S2, the support position of the bushing is adjusted by the positioning bolts on the central support so that the bushing is set parallel to the axis of the bearing seat.

[0013] Preferably, the bushing has a plurality of circumferentially distributed clamping members at the end away from the chuck, and the roller core is supported on the end of the bushing away from the chuck by the clamping members;

[0014] In S4, adjusting the position of the annular support relative to the end of the roller core away from the chuck specifically involves adjusting the radial feed amount of the clamping member.

[0015] In this invention, the proposed method for compensating for the concentricity of the traction roller involves clamping one end of the bushing with a chuck and supporting the middle of the bushing with a central bracket, ensuring the bushing is parallel to the axis of the bearing seat. The end of the roller core furthest from the short roller passes through the bushing, aligning the annular support portion of the roller core with the end of the bushing furthest from the chuck. The position of the annular support portion relative to the end of the roller core furthest from the chuck is adjusted based on the measured runout of the roller core to compensate for the runout. Through this optimized compensation method, before the material is applied to the outside of the short roller boss of the traction roller, the mating position of the roller core and the bushing is adjusted according to the runout of the roller core. This compensates for the eccentricity of the traction roller relative to the axis of the bearing seat, ensuring the concentricity of the short roller boss during material application and thus preventing the impact of traction roller deformation on glass production.

[0016] The present invention also proposes an adjustment device for realizing the above-mentioned traction roller concentricity compensation method, comprising: a chuck, a central support, a bushing, and an adjustment assembly;

[0017] The chuck holds one end of the bushing, the central bracket supports the middle of the bushing, and the adjustment assembly includes a clamping seat, at least three clamping parts, and a drive mechanism.

[0018] The adjustment assembly is installed at the end of the bushing away from the chuck. The clamping seat has an opening in the middle for the roller core to pass through. The plurality of clamping members are distributed around the opening. The drive mechanism is used to adjust the extension length of the clamping member in the opening to adjust the clamping end position of the clamping member.

[0019] Preferably, it further includes:

[0020] The testing mechanism is used to detect the runout of the support portion on the core of the traction roller relative to the axis of the bearing housing.

[0021] Preferably, the detection mechanism includes a bearing housing for mounting the roller core and a rangefinder located on one side of the roller core;

[0022] The distance measuring instrument is used to measure the distance to the annular support on the outer wall of the roller core.

[0023] Preferably, the central support includes a frame and a plurality of positioning bolts mounted on the frame, with the ends of the positioning bolts abutting against the outer wall of the bushing.

[0024] Preferably, the drive mechanism includes multiple drive motors, each drive motor being connected to each clamping member for driving the clamping member to feed or retract.

[0025] Preferably, the clamping base is provided with a threaded locking screw, which extends away from the clamping member, and the clamping member is provided with an external thread that engages with and limits the end of the locking screw.

[0026] The traction roller concentricity compensation device proposed in this invention has similar technical effects to the compensation method described above, so it will not be described in detail here. Attached Figure Description

[0030] like Figures 1 to 3 As shown, Figure 1 This is a schematic diagram of the detection mechanism of one embodiment of the traction roller concentricity compensation device proposed in this invention. Figure 2 This is a schematic diagram of the adjustment section of one embodiment of the traction roller concentricity compensation device proposed in this invention. Figure 3 This is a partial structural diagram of the clamping member and the roller core in one embodiment of the traction roller concentricity compensation device proposed in this invention.

[0031] Reference Figure 1 and 2 The present invention proposes a traction roller concentricity compensation device, comprising: a chuck 1, a central support, a bushing 2, and an adjustment assembly;

[0032] The chuck 1 clamps one end of the bushing 2, the central bracket supports the middle of the bushing 2, and the adjustment assembly includes a clamping seat 51, at least three clamping parts 52 and a drive mechanism.

[0033] The adjustment assembly is installed on the end of the bushing 2 away from the chuck 1. The clamping seat 51 has an opening in the middle for the roller core 10 to pass through. The plurality of clamping members 52 are distributed around the opening. The drive mechanism is used to adjust the extension length of the clamping member 52 in the opening to adjust the clamping end position of the clamping member 52.

[0034] The compensation method of the compensation device in this embodiment includes the following steps:

[0035] S1. Measure the runout of the roller core 10;

[0036] In this embodiment, the compensation device further includes a detection mechanism for detecting the runout of the annular support portion on the roller core 10 of the traction roller relative to the axis of the bearing seat. Specifically, the detection mechanism includes a bearing seat 4 for mounting the roller core 10 and a distance measuring instrument 3 located on one side of the roller core 10; the distance measuring instrument 3 is used to measure the distance to the annular support portion on the outer wall of the roller core 10.

[0037] In the specific measurement of runout, the roller core 10 of the traction roller is first horizontally mounted on the bearing seat 4, engaging with the two bearing stops of the bearing seat. The roller core 10 is then rotated, and a distance measuring instrument 3 is placed on the side of the roller core 10 closest to the short roller 20. The distances to at least three points on the annular support portion of the outer wall of the roller core 10 closest to the short roller 20 are measured using the distance measuring instrument 3 to obtain the runout of the roller core 10. In actual use, a laser distance measuring instrument can be used to ensure measurement accuracy.

[0038] S2. Clamp one end of the bushing 2 with the chuck 1 and support the middle part of the bushing 2 with the central bracket, so that the bushing 2 is set parallel to the axis of the bearing seat 4.

[0039] In the specific design of the central support, the central support includes a frame 61 and multiple positioning bolts 62 mounted on the frame 61. The ends of the positioning bolts 62 abut against the outer wall of the bushing 2. During installation, the bushing 2 has multiple circumferentially distributed clamping members 52 at the end away from the chuck 1, and the roller core 10 is supported on the end of the bushing 2 away from the chuck 1 by the clamping members 52. During adjustment, the support position of the bushing 2 is adjusted by the clamping members 52 on the central support, so that the bushing 2 is set parallel to the axis of the bearing seat 4.

[0040] S3. Pass the end of the roller core 10 away from the short roller 20 through the bushing 2, so that the annular support part of the roller core 10 corresponds to the end of the bushing 2 away from the chuck 1.

[0041] S4. Adjust the position of the annular support relative to the end of the roller core 10 away from the chuck 1 based on the runout amount obtained in S1, so as to compensate for the runout amount.

[0042] During the adjustment and compensation process, the position of the annular support portion of the roller core is adjusted by adjusting the radial feed amount of the clamping member 52.

[0043] To avoid errors caused by the roller core installation position during compensation and measurement, a circumferentially extending scale can be set on the roller core. The roller core is installed with reference to the scale on the scale, and the detected roller core runout is precisely correlated with the radial adjustment direction of the adjustment component.

[0044] In addition, in order to achieve automated adjustment and ensure adjustment accuracy, in the specific design of the adjustment component in this embodiment, the drive mechanism includes multiple drive motors 53, each drive motor 53 is connected to a clamping member 52 for driving the clamping member 52 to feed or retract.

[0045] Reference Figure 3 In a further specific design, the clamping seat 51 is equipped with a threaded locking screw 54, which extends away from the clamping member 52. The clamping member 52 has an external thread that engages with the end of the locking screw 54 for positioning. After compensation adjustment, the position of the clamping member is locked by the engagement of the locking screw with the external thread on the outer wall of the clamping member. During subsequent processing, the chuck drives the bushing to rotate, thereby driving the rotation of the roller core, ensuring the uniformity of the axis between the two bearing seats of the bearing housing when processing the coating material on the short roller boss.

[0046] To achieve automated detection, during actual measurement, the roller core can be connected to the servo motor 7. Every 60 degrees the servo motor rotates, the distance measuring instrument detects the distance to the roller core shaft surface. Through data processing, the chuck automatically adjusts and clamps accordingly using the compensation part.

[0047] In this embodiment, the proposed traction roller concentricity compensation device and method clamp one end of the bushing with a chuck and support the middle of the bushing with a central bracket, so that the bushing is parallel to the axis of the bearing seat. The end of the roller core away from the short roller passes through the bushing, so that the annular support part of the roller core corresponds to the end of the bushing away from the chuck. The position of the annular support part relative to the end of the roller core away from the chuck is adjusted according to the measured runout of the roller core to compensate for the runout. Through the above-described optimized compensation method, before the material is wrapped around the short roller boss of the traction roller, the mating position of the roller core and the bushing is adjusted according to the runout of the roller core, and the eccentricity of the traction roller relative to the axis of the bearing seat is compensated, ensuring the concentricity of the short roller boss when wrapping the material, thereby avoiding the impact of traction roller deformation on glass production.

[0048] In actual operation, the bearing housing can be directly adopted from the mounting base of the traction roller in the glass traction equipment. During testing, the bearing housing and roller core are tested as a whole. After the compensated short roller is covered with a coating material, the roller core is remounted on the glass traction device through the bearing housing to adapt to the actual working environment of the traction roller.

[0049] Similarly, the compensation device can directly modify the short roller boss material coating equipment. The chuck adopts the driving chuck of the coating equipment to compensate for the runout of the boss before coating in the coating equipment.

[0050] The following examples illustrate the specific compensation process of the traction roller concentricity compensation device and method in this embodiment.

[0051] This embodiment provides a processing device for overcoming roller core deformation. The device includes a roller core runout detection section and an automatic adjustment and compensation clamping section for the jaws. The roller core runout detection section includes a bearing housing, a rangefinder, a servo motor, and a dial; the automatic adjustment and compensation section for the jaws includes a three-jaw chuck, a bushing, a servo motor, a single-acting jaw, fastening screws, and a center rest.

[0052] The roller core is inspected on the tooling to reflect the change in distance between the centerline of the two bearing stops and the surface of the roller core material. The actual deformation is detected by a lever dial indicator. Based on this idea, an invention was made on how to avoid and overcome deformation while ensuring the coaxiality requirement of the two bearing stops. A servo motor is installed on the bearing housing, and a rangefinder is installed at the support position. The traction roller is installed on the bearing housing. The servo motor is driven by a program to measure once every 60 degrees, detecting the actual distance on the shaft surface and the position difference of the three fixed points. The data is processed in the background and transmitted to the servo motor to drive the single chuck to move. The actual detection data is compensated to ensure that the roller core and the single chuck directly contact the roller core surface. At the same time, the three chucks cooperate to firmly clamp the roller core and keep it fixed. The rotation of the machine tool drives the outer roller to rotate.

[0053] Therefore, during the detection of roller core runout, the roller core is mounted on the bearing seat. Every 60 degrees the servo motor rotates, the distance measuring instrument detects the distance to the roller core shaft surface. Through data processing, the chuck automatically adjusts and clamps accordingly using the compensation part.

[0054] During automatic adjustment and compensation of the chuck jaws, the bushing needs to be concentric with the three-jaw chuck, and the center support part also needs to be aligned and the concentricity of the support position needs to be checked. After the above operations are completed, keep it still, insert the roller core into the bushing and cooperate with the bearing stop at the front end of the roller core, start the program to control the individual chuck jaws to place the roller core according to the detection data of the roller core detection part and the corresponding detection position, and the action of the individual chuck jaws to compensate and clamp the roller core according to the detection distance difference. At the same time, tighten the locking screws. After the above steps are completed, ensure the coaxiality requirement of the two bearing stops of the roller core, start the machine tool to drive the bushing on the three-jaw chuck to rotate, and process the short roller boss part to avoid physical interference caused by the deformation of the support position.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
