Through the rotation of the drive motor, the workbench can slide along the length direction of the bed.

[0052] The workbench is equipped with a clamping assembly for clamping the corrugating roller, and the clamping assembly can drive the corrugating roller to rotate. The clamping assembly in this embodiment includes two work brackets 4, a clamping device, and a rotating device. More than two work brackets can be provided; the two work brackets are respectively arranged at the two ends of the workbench in the longitudinal direction. The clamping device and driving device are arranged at one end of the workbench. In this embodiment, the clamping device is a four-jaw chuck 5, and the rotating device is a workpiece indexing turntable 6. The four-jaw chuck is used to clamp the end of the corrugating roller. The four-jaw chuck is arranged at the output end of the workpiece indexing turntable. The rotation of the workpiece indexing turntable can drive the four-jaw chuck to rotate, thereby rotating the corrugating roller. In addition, there is a cross slide between the workpiece indexing turntable and the four-jaw chuck. The cross slide allows the corrugated roller workpiece to always be in contact with the working bearing when the corrugated roller workpiece rotates, so that the rotation accuracy and grinding accuracy of the corrugated roller workpiece are no longer affected by the different axial quantities between the axis of the corrugated roller workpiece and the axis of the workpiece indexing turntable. The workpiece indexing turntable only needs to provide rotation, thereby minimizing the impact on the grinding accuracy of the corrugated roller workpiece; the four-jaw chuck, workpiece indexing table and cross slide are all existing technologies.

[0053] The work bracket mainly includes a work support plate 41 that is slidably mounted on the workbench, a work pad 42, and a work bearing 43. The work pad is mounted on the work support plate, and two work bearings are provided.

A crossbeam motor 321 is provided at the end of the crossbeam chute, and a crossbeam screw 322 is provided at the output end of the crossbeam motor. A crossbeam slider is provided on the mounting plate to cooperate with the crossbeam screw. The crossbeam motor drives the crossbeam screw to rotate, causing the mounting plate to slide along the crossbeam chute, thereby enabling the grinding head, grinding wheel dresser, and tool setting and measuring device to slide synchronously in the transverse direction of the worktable. In addition, a grating scale is also provided on the mounting plate to accurately record the displacement of the mounting plate on the crossbeam, thereby accurately recording the displacement of the grinding head and tool setting and measuring device in the transverse direction of the worktable.

A mounting plate motor 711 is provided at the end of the mounting plate slot, and a mounting plate screw is provided at the output end of the mounting plate motor. A mounting plate slider that cooperates with the mounting plate screw is provided on the grinding head support plate; the mounting plate motor drives the mounting plate screw to rotate, so that the grinding head support plate slides along the mounting plate slot, thereby controlling the grinding head, the grinding wheel dresser and the tool setting measuring device to move downward synchronously, so that the tool setting measuring device can contact the surface of the corrugated roller workpiece, thereby measuring the parameter coordinates related to the corrugated roller workpiece.

[0059] A grinding head chute is provided on the grinding head support plate, and the dresser support plate is slidably provided on the grinding head chute. A grinding head motor 723 is provided at the end of the grinding head chute, and a grinding head screw is provided at the output end of the grinding head motor. A dresser slider matching the grinding head screw is provided on the dresser support plate; the grinding head motor drives the grinding head screw to rotate, so that the dresser support plate moves along the grinding head chute, so that the grinding wheel dresser can move toward or away from the grinding head, thereby realizing the grinding of the grinding head.

[0060] The working principle of the present invention is as follows, mainly including the following three situations:

[0061] 1. Clamping of corrugated roller

[0062] There are bearing blocks at both ends of the corrugated roller workpiece. First, before clamping the corrugated roller workpiece, select the thickness of the corresponding adjustment gasket according to the shaft diameter of the bearing blocks at both ends of the corrugated roller, so that the axis center of the corrugated roller workpiece and the axis center of the workpiece indexing turntable are at the same height, and adjust the distance between the two working brackets so that the bearing blocks at both ends of the corrugated roller can just abut against the working bracket; then place the corrugated roller workpiece to be ground on the corresponding working bearing, so that the bearing blocks at both ends of the corrugated roller workpiece abut against the working bearing, thereby installing the corrugated roller workpiece on the workpiece bracket; then use a four-jaw chuck to clamp one end of the corrugated roller workpiece, and the clamping of the corrugated roller workpiece is completed.

[0063] 2. Blade setting of corrugated roller

[0064] In the first step, the workpiece indexing turntable rotates to rotate the corrugating roller workpiece, and the tool setting measuring device is moved to measure the center coordinates of the tooth root of the corrugating roller workpiece, so that the axis of the tooth root center of the corrugating roller can be calculated. Similarly, the center coordinates of the bearing blocks at both ends are measured by the tool setting measuring device to calculate the axis of the corrugating roller workpiece; and the center axis of the corrugating roller workpiece and the center axis of the tooth root are made to coincide in the same vertical plane.

[0065] In the second step, the workpiece indexing turntable rotates to rotate the corrugating roller workpiece, and the tool setting measuring device is moved to measure the center coordinates of the tooth profile (the average value of the contact coordinates of the two sides of the tooth profile and the tool setting measuring device at the same height during measurement) to obtain the axis coordinates of the tooth profile center; and by rotating the workpiece indexing turntable, the center axis of the tooth profile of the corrugating roller workpiece and the axis of the corrugating roller workpiece are made to coincide in the same vertical plane;

[0066] In the third step, the grinding wheel dresser moves downward to dress the grinding head and shape it. Then the grinding head descends to grind the tooth surface so that the side surfaces of the two adjacent teeth are in contact with the grinding head, so that the side surfaces of the teeth on both sides are polished to a shine at the same time.

[0067] The fourth step is to measure the center coordinates of the two visible tooth profiles (when measuring, at the same height, the average value of the contact coordinates of the tooth profile on both sides and the tool setting measuring device), and obtain the axis coordinate of the center of the visible tooth profile. Compare the axis coordinate of the center of the visible tooth profile with the axis coordinate of the corrugated roller workpiece. If there is a deviation between the two coordinates, move the grinding head along the horizontal direction of the workbench to make the two center coordinates consistent.

[0068] 3. Grinding of corrugated rollers

[0069] The workbench drives the workpiece indexing turntable, the workpiece bracket and the corrugated roller workpiece to move along the bed; the grinding head support plate does not move laterally; when the grinding wheel is disengaged from the corrugated roller workpiece and the workbench is ready to change direction, the dresser support plate drives the grinding wheel dresser to move downward, and the grinding wheel dresser grinds the grinding head; because both the dresser support plate and the grinding head support plate are provided with grating scales, after the grinding wheel dresser grinds the grinding head, the grinding amount of the grinding wheel dresser can be compensated to the feed amount of the grinding head, so that after each grinding of the grinding head, the grinding head can perform precise feed, thereby achieving precise control of the grinding amount.

[0070] This embodiment has the following advantages:

[0071] 1. The tool setting operation is simple and convenient, and can be quickly performed without the use of third-party tools;

[0072] 2. The grinding head and tool setting measuring device are fixedly installed on the same grinding head support plate, which makes the tool setting highly accurate and eliminates the error of the measuring tool;

[0073] 3. The grinding wheel dresser is arranged above the grinding head, which can dress the grinding wheel at any time without the need for workbench travel, saving dressing time and improving the efficiency of grinding tooth profile, thereby improving the efficiency of the entire corrugated roller workpiece processing;

[0074] 4. Both the dresser support plate and the grinding head support plate are equipped with grating scales. Therefore, after the grinding wheel dresser grinds the grinding head, the grinding amount of the grinding wheel dresser can be compensated to the feed amount of the grinding head, realizing precise control of the grinding amount.

[0075] 5. The workpiece grinding accuracy is separated from the workpiece clamping accuracy, reducing the dependence on workers' technical skills.

[0076] Example 2: Reference Figures 1 to 4 As shown, this embodiment is similar in structure to the first embodiment, except that a mounting slot 411 is provided on the work support plate, extending along the width of the workbench, and the bottom of the work pad is mounted within the mounting slot. Fixing blocks 412 are provided at both ends of the mounting slot, each having a fixing hole 413. Bolts are threaded into the fixing holes, and the bolts engage with the fixing holes, with the ends of the bolts abutting the work pad. By rotating the bolts, the bolts abut against the work pad, thereby enabling fine-tuning of the work pad in the lateral direction of the workbench. In the first embodiment, vertical axis deviation can be adjusted by controlling the raising and lowering of the grinding head.

[0077] Therefore, by cooperating with the working pad and the bolt, it is possible to easily adjust the error in the horizontal direction.

[0078] Example 3: A gantry-type corrugated roller grinder tool setting method, which utilizes the gantry-type corrugated roller grinder in Example 1 or Example 2, mainly includes the following steps:

[0079] The first step is to use the tool setting measuring device to measure the center coordinates of the corrugating roller bearing gear and calculate the axis of the corrugating roller workpiece;

[0080] The second step is to use the tool setting measuring device to measure the center coordinates of the tooth root of the corrugated roller workpiece, calculate the axis coordinates of the tooth root center of the corrugated roller workpiece, and adjust the corrugated roller so that the axis of the tooth root center of the corrugated roller workpiece and the axis of the corrugated roller workpiece are in the same vertical plane;

[0081] The third step is to use the tool setting measuring device to measure the center coordinates of the tooth profile of the corrugated roller workpiece, calculate the axis of the tooth profile center of the corrugated tube workpiece, and adjust the corrugated roller so that the axis of the tooth profile center of the corrugated roller workpiece and the axis of the corrugated roller workpiece are in the same vertical plane;

[0082] The fourth step is to grind the tooth surface of the corrugated roller with the grinding head so that the side surfaces of the two adjacent teeth are in contact with the grinding head, so that the side surfaces of the teeth on both sides are polished to a light finish at the same time;

[0083] Step 5. Measure the center coordinates of the two visible tooth shapes to obtain the axis of the center of the visible tooth shape. Compare the coordinates of the center axis of the visible tooth shape with the center coordinates of the axis of the corrugated roller workpiece. If there is a deviation between the two coordinates, move the grinding head along the horizontal direction of the workbench to make the two center coordinates consistent; complete the tool setting.

[0084] In this embodiment, through the above steps, accurate and rapid tool setting can be achieved, effectively improving the processing efficiency of the corrugated roller workpiece.

[0085] The above-described embodiments are only preferred solutions of the present invention and are not intended to limit the present invention in any form. Other variations and modifications are possible without exceeding the technical solutions described in the claims.
