[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0027] like Figure 1 As shown, the gear shaping cutter installation and correction device includes a gear shaping cutter body 3 and also includes:

[0028] The fixing mechanism 1 is arranged at the bottom of the gear shaping cutter body 3 and is used for fixing the gear shaping cutter body 3 .

[0029] The correction mechanism 2 is arranged on the top of the fixing mechanism 1 and is used for correcting the installation of the gear shaping cutter body 3 .

[0030] In order to conveniently install and fix the correction mechanism 2, as Figure 2 and Figure 3 As shown, the fixing mechanism 1 includes a fixing base 101, a mounting groove 102 is provided on the top of the fixing base 101, mounting holes 104 are provided at both ends of the outer wall of one side of the fixing base 101, the mounting groove 102 can be used to install and fix the permanent magnet 201, and the mounting hole 104 can be used to install and fix the calibration bar 204.

[0031] In order to conveniently correct the installation of the gear shaping cutter body 3, as Figure 2 and Figure 4 As shown, the correction mechanism 2 includes a permanent magnet 201 and a calibration bar 204. The permanent magnet 201 is arranged on the inner wall of the mounting groove 102. The top of the permanent magnet 201 is magnetically connected to the bottom of the gear shaping cutter body 3. A countersunk screw 203 is arranged between the inner wall of the permanent magnet 201 and the fixed base 101. The calibration bar 204 is arranged on the outer wall of one end of the fixed base 101. Fastening bolts 206 are arranged between both ends of the inner wall of the calibration bar 204 and the two mounting holes 104. The radial direction of the gear shaping cutter body 3 can be limited by the calibration bar 204, and the installation of the gear shaping cutter body 3 can be calibrated.

[0032] In order to conveniently install and remove the permanent magnet 201, Figure 2-4 As shown, the fixing mechanism 1 includes a fixing hole 103, which is opened at the middle position of the bottom of the inner wall of the installation groove 102, and the inner wall of the fixing hole 103 is threadedly connected with the screw part of the countersunk screw 203. A fixing groove 202 is opened in the middle of the inner wall of the permanent magnet 201, and the fixing groove 202 is arranged directly above the fixing hole 103. The inner wall of the fixing groove 202 is movably connected with the screw head part of the countersunk screw 203, and the countersunk screw 203 passes through the fixing groove 202 and is threadedly connected with the inner wall of the fixing hole 103, so that the permanent magnet 201 can be stably fixed to the installation groove 102.

[0033] In order to facilitate the installation and removal of the calibration strip 204, Figure 2-4 As shown, the correction mechanism 2 includes a connecting hole 205, and two connecting holes 205 are provided. The two connecting holes 205 are respectively opened on the inner walls of the two ends of the calibration strip 204, and the inner wall of the connecting hole 205 is threadedly connected to the outer wall of the adjacent fastening bolt 206. The side of the fastening bolt 206 away from the connecting hole 205 is threadedly connected to the inner wall of the adjacent mounting hole 104. The fastening bolt 206 passes through the connecting hole 205 and is threadedly connected to the inner wall of the adjacent mounting hole 104, so that the calibration strip 204 can be stably fixed to the outer wall of one side of the fixed base 101, so that it can stably correct the installation of the gear cutter body 3.

[0034] In order to enable the device to stably calibrate the gear shaping cutter body 3, as Figure 2 As shown, the top end surface of the installed permanent magnet 201 is 0.5 mm lower than the top end surface of the fixed base 101, the top end surface of the permanent magnet 201 is 1 mm lower than the top end surface of the calibration bar 204, and the outer diameter of the permanent magnet 201 is larger than the top circle diameter of the gear cutter body 3.

[0035] The specific implementation method is as follows: when installing and calibrating the gear shaping cutter body 3, the permanent magnet 201 is placed on the top of the installation groove 102, so that the fixing groove 202 can be aligned with the fixing hole 103, and then the countersunk screw 203 is used to penetrate the inner wall of the fixing groove 202 and is threadedly connected to the inner wall of the fixing hole 103, so that the permanent magnet 201 can be stably fixed to the top of the installation groove 102, and the end face of the installed permanent magnet 201 is 0.5mm lower than the top end face of the fixed base 101, and then the calibration bar 204 is installed to one end opening of the fixed base 101, so that the connecting hole 205 can be aligned with the adjacent mounting hole 104, and then the fastening bolt 206 is used to penetrate the connecting hole 205 and is threadedly connected to the inner wall of the adjacent mounting hole 104, so that the calibration bar 204 can be stably fixed to the outer wall of one side of the fixed base 101, so that the upper end face of the calibration bar 204 is 1mm higher than the end face of the permanent magnet 201, which plays a role in limiting the radial direction of the gear shaping cutter body 3 in the fixed base 101.

[0036] The main function of the utility model is to provide a correction auxiliary device when adjusting the angle of the gear shaping cutter, so as to help the gear shaping machine obtain the angle parameter that needs to be adjusted.

[0037] When the utility model is used to install and correct the gear shaping cutter, the existing parameter rotation adjustment function of the gear shaping machine itself is used.

[0038] like Figure 5 and Figure 6 As shown, the gear shaping cutter body 3 is installed on the gear shaping machine spindle. After the first part is processed and qualified, the gear shaping machine spindle returns to the original position (zero position) and records the current gear shaping machine spindle angle coordinate value. The device is adsorbed on the tip surface of the gear shaping cutter body 3, and the device is moved horizontally along the Y axis and slowly rotated until the two tooth top edges of the gear shaping cutter body 3 are completely in contact with the front end surface of the calibration bar 204, as shown in FIG. Figure 6 A micrometer is set on the gear shaping machine workbench, and the micrometer head is perpendicular to the front end surface of the calibration bar 204. The gear shaping machine spindle is moved left and right along the X-axis direction. According to the change of the micrometer value, the gear shaping machine spindle angle is adjusted until the micrometer value changes within 0.001. The gear shaping machine spindle angle coordinate value at this time is recorded, and the adjustment angle coordinate difference of the gear shaping cutter body 3 (original spindle angle coordinate value - corrected spindle angle coordinate value) is calculated.

[0039] When replacing the gear shaping cutter body 3, return the gear shaping machine spindle to its original position (the position after calibration in the previous stage). Remove the gear shaping cutter to be replaced, install the new gear shaping cutter body 3, and calibrate the newly installed gear shaping cutter body 3 according to the above-mentioned calibration method. Record the spindle angle coordinate value after the calibration is completed. Calculate the spindle angle coordinate value required for adjustment (the spindle angle coordinate value after calibration + the adjustment angle coordinate difference of the previous gear shaping cutter). Input the calculated spindle angle coordinate value into the spindle angle parameter of the gear shaping machine. After starting the gear shaping machine, the spindle rotates according to the input angle parameter value to ensure that the replaced gear shaping cutter body 3 has the same angular position as the gear shaping cutter body 3 before replacement, thereby ensuring that the center symmetry of the processed part teeth or tooth grooves meets the precision requirements. This embodiment specifically solves the problem in the prior art that the installation of the gear shaping cutter cannot be corrected, which affects the machining accuracy.
