[0026] The utility model is further described in detail below in conjunction with the accompanying drawings. It is necessary to point out that the following specific implementation methods are only used to further illustrate the utility model and cannot be understood as limiting the scope of protection of the utility model. Technical personnel in this field can make some non-essential improvements and adjustments to the utility model based on the above application content.

[0027] Example:

[0028] like Figure 1 , 2 As shown in Figure 3, the utility model provides an adjustable gear hobbing cutter correction seat, which is used to correct the gear hobbing cutter (not shown) sleeved on the cutter bar 301, including a base 101, on which a rotating assembly, an abutting assembly and a limiting mechanism are arranged, and the cutter bar 301 is driven to rotate by the rotating assembly, and the rotating assembly includes a rotating spindle 103, and the rotating spindle 103 is rotatably arranged on the base 101 along its axis, and the end of the cutter bar 301 is inserted into the rotating spindle 103, and a clamping groove 302 is opened at the end of the cutter bar 301, and a clamping block 104 is arranged in the rotating spindle 103, and the clamping block 104 is clamped in the clamping groove 302. A rotating member 105 is arranged at the end of the rotating spindle 103.

[0029] When the correction seat is in use, the gear hobbing cutter is mounted on the cutter bar 301, and the cutter bar 301 is fixed to the cutter bar 301 by bolts. After fixing, the end of the cutter bar 301 is inserted into the inner opening of the rotating spindle 103, and the rotating spindle 103 is controlled to rotate by the rotating member 105, so as to drive the cutter bar 301 and the gear hobbing cutter mounted thereon to rotate. In addition, it can be understood that in some embodiments, the rotating member 105 can be manually controlled to rotate to drive the rotating spindle 103 to rotate, and the rotating member 105 can also be connected to the output shaft of the motor or motor to rotate the rotating member 105 by electric control.

[0030] like Figure 1 , 2 As shown, in this embodiment, the abutment assembly is connected to the other end of the tool rod 301 to axially limit the tool rod 301. The abutment assembly includes a threaded sleeve 201. A slide groove 102 is provided on the base 101. The threaded sleeve 201 can be slidably clamped in the slide groove 102. An abutment rod 202 is threaded in the threaded sleeve 201. An abutment cone 203 is provided at the end of the abutment rod 202. The abutment cone 203 is inserted into the clamping hole at one end of the tool rod 301.

[0031] In the process of connecting one end of the tool rod 301 with the rotating main shaft 103, the abutment rod 202 can also be rotated to make it move horizontally in the threaded sleeve 201, so that the abutment cone 203 at its end is inserted into the clamping hole at one end of the tool rod 301, so as to prevent the tool rod 301 from axially moving and disengaging from the rotating main shaft 103 during the process of controlling the rotation of the tool rod 301, thereby improving the stability during correction. In addition, the threaded sleeve 201 can only slide in the slide groove 102 but cannot rotate, so that when installing the tool rod 301, the abutment rod 202 can be moved up and down to quickly align the abutment cone 203 with the clamping hole at the end of the tool rod 301, thereby improving the installation efficiency, and the position of the abutment rod 202 can be adjusted to adapt to the use of tool rods 301 of different lengths.

[0032] like Figure 1 , 3 As shown, in this embodiment, the limiting mechanism abuts against the circumference of the knife rod 301 to radially limit the knife rod 301. The limiting mechanism includes two sets of sliders 404. The base 101 is provided with a mounting groove 401. Both sets of sliders 404 are slidably mounted in the mounting groove 401. An adjustment component for driving the two sets of sliders 404 to slide is also provided in the mounting groove 401. The sliders 404 are provided with limiting rollers 405, and the limiting rollers 405 abut against the circumference of the knife rod 301. The adjustment component includes a bidirectional screw 402. The bidirectional screw 402 is rotatably arranged in the mounting groove 401 along its axis. The two sets of sliders 404 are respectively screwed at both ends of the bidirectional screw 402. An adjustment wheel 403 is also provided at the end of the bidirectional screw 402.

[0033] After the knife bar 301 is installed, the bidirectional screw 402 can be driven to rotate by rotating the adjusting wheel 403. During the rotation process, the bidirectional screw 402 can drive the two sets of sliders 404 to slide in opposite directions in the installation groove 401 through the threads at both ends rotating in opposite directions. By controlling the two sets of sliders 404 to close, the two sets of limiting rollers 405 are driven to close until the two sets of limiting rollers 405 abut against the knife bar 301, which can effectively prevent the knife bar 301 from moving during the rotation process and improve the correction accuracy. The spacing between the two sets of limiting rollers 405 can also be adjusted to adapt to the use of knife bars 301 with different diameters.

[0034] Specific usage and beneficial effects of the utility model:

[0035] When the correction seat is in use, the gear hobbing cutter sleeve is placed on the cutter bar 301 and the gear hobbing cutter is fixed by bolts, and then one end of the cutter bar 301 is connected to the rotating spindle 103, and the clamping block 104 is clamped in the clamping groove 302, and the other end is used to axially limit the cutter bar 301 through the cooperation of the abutment rod 202 and the abutment cone 203, and the cutter bar 301 is radially limited by the abutment of the limiting roller 405 with the peripheral side of the cutter bar 301 to prevent the cutter bar 301 from lateral movement, and the rotating spindle 103 is controlled to rotate. 03 rotates to drive the tool bar 301 and the gear hobbing cutter to rotate. The runout of the gear hobbing cutter is measured by a runout meter during the rotation of the gear hobbing cutter, so that it can be known whether the installation position of the gear hobbing cutter on the tool bar 301 meets the use standard. If the runout value is too large, the bolt is adjusted to quickly correct the installation of the gear hobbing cutter. The installation position of the gear hobbing cutter can be quickly corrected through the correction seat, and the movement of the tool bar 301 during the rotation process can be reduced as much as possible to improve the accuracy of the gear hobbing cutter processing.

For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments. On the basis of the utility model, some modifications or improvements can be made thereto, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not departing from the spirit of the utility model all belong to the scope of protection claimed by the utility model.
