In actual use, The operator first places the gear 8 to be processed on the top of the rotating table 13, and allows the top of the column 131 to penetrate the top of the gear 8 to be processed, and then places the pressing sleeve 14 on the top surface of the gear 8 to be processed, and allows the top of the column 131 to be inserted into the inner side of the pressing sleeve 14. At this time, the push rod 12 is rotated downward clockwise so that the bottom end of the push rod 12 presses the pressing sleeve 14 tightly, and the vertical pressing limit of the gear 8 to be processed can be achieved. At this time, the gear hobbing machine is started, and the motor seat 3 drives the rotating seat 7 to rotate. When the rotating seat 7 rotates, the rod seat 15, the support rod 16, the rotating table 13 and the gear 8 to be processed will also rotate. When the gear hobbing machine is started, the gear hobbing cutter 6 will also start to rotate. At the same time, the sliding machine seat 2 will slide toward the gear hobbing cutter 6, causing the gear hobbing cutter 6 to contact the edge of the gear 8 to be processed, and the gear hobbing of the gear 8 to be processed can be achieved. An adjustment mechanism is provided between the rod seat 15 and the support rod 16;

[0020] The adjusting mechanism includes a socket 171, an adjusting through-block 172 and a through-hole 173. The front and rear surfaces of the rod seat 15 are penetrated with a socket 171 corresponding to the adjusting through-block 172. The surface of the support rod 16 is penetrated with a plurality of through-holes 173 corresponding to the adjusting through-block 172. The adjusting through-block 172 penetrates one of the through-holes 173, and the two ends of the adjusting through-block 172 are respectively located in the two sockets 171 on the front and rear surfaces of the rod seat 15. The adjusted through-block 172 after penetration can be inserted between the rod seat 15 and the support rod 16 to ensure the supporting stability of the support rod 16. Subsequently, the height of the support rod 16, the rotating table 13 and the gear 8 to be processed can be changed by only passing the adjusting through-block 172 through the through-holes 173 at other positions.

[0021] Among them, a movable groove 151 is opened inside the rod seat 15, and side sliding grooves 152 are opened on the inner walls on both sides of the movable groove 151. The bottom end of the support rod 16 slides in the movable groove 151, and side sliding blocks 161 are fixed on both sides of the bottom end of the support rod 16. The side sliding blocks 161 slide in the side sliding grooves 152, so that the support rod 16 can be stably raised and lowered at the top of the rod seat 15, and the support rod 16 will also rotate with the rod seat 15.

[0022] Among them, the adjustment mechanism also includes an inner groove 174 opened in the adjustment wear block 172, and a spring 175 and a telescopic bead 176 are arranged in the inner groove 174. A limiting card hole 177 corresponding to the telescopic bead 176 is opened on the inner wall of one side of the through hole 173. The telescopic bead 176 is movably installed in the inner groove 174 through the spring 175, and the top of the telescopic bead 176 pops out into one of the limiting card holes 177 to achieve the engagement and limitation of the adjustment wear block 172 after it passes through the through hole 173. If the height of the rotating table 13 and the gear 8 to be processed is to be adjusted later, it is only necessary to push the adjustment wear block 172 with force from the socket 171 on the surface of the rod seat 15, so that the telescopic bead 176 is squeezed and gradually squeezed into the inner groove 174, so that the telescopic bead 176 can be prevented from The adjusting threading block 172 is then limited. At this time, the adjusting threading block 172 can be smoothly pushed out, so that the support rod 16 is no longer limited. At this time, the operator can slide the support rod 16 up and down to adjust the height of the rotating table 13 and the gear 8 to be processed. When it is adjusted to a suitable height, the adjusting threading block 172 is inserted back into the insertion hole 171 again, and the adjusting threading block 172 can pass through the through holes 173 at other positions until the top of the telescopic card bead 176 can be inserted into the limiting card hole 177 on the inner wall of the through hole 173 under the push of the spring 175, and the adjusting threading block 172 can be limited again. At this time, the adjusting threading block 172 is inserted between the rod seat 15 and the support rod 16, thereby completing the stable limitation of the support rod 16, thereby completing the height adjustment of the rotating table 13 and the gear 8 to be processed.

[0023] Among them, a lifting seat 10 is arranged on the right side surface of the vertical plate 9, and a base block 11 is fixed on the right side surface of the lifting seat 10. A push rod 12 is threaded through the base block 11, and the bottom end of the push rod 12 extends to the top of the gear 8 to be processed and presses the pressing sleeve 14 tightly, so that after the subsequent pressing sleeve 14 is placed on the top of the gear 8 to be processed, the operator can rotate and twist the push rod 12 so that the push rod 12 rotates and moves downward under the action of the thread until the bottom end of the push rod 12 presses the pressing sleeve 14 tightly, thereby realizing the pressing and limiting of the gear 8 to be processed, which is convenient for the subsequent gear hobbing processing of the gear 8 to be processed.

[0024] Example 2

[0025] See also Figures 1 to 5, which is the second embodiment of the utility model. This embodiment is based on the previous embodiment, and the difference is that the gear 8 to be processed can be placed on the top of the rotating table 13 and fixed tightly by setting a fixed structure, so as to ensure the stability during the subsequent gear hobbing process.

[0026] Specifically, it also includes a fixed structure, which is arranged on the column 131. The fixed structure includes an active cavity 132 that penetrates and is opened on the surface of the column 131. Two rotating support blocks 138 are rotatably installed in the active cavity 132, and the bottom end of the rotating support block 138 extends to the outside of the column 131 and is in close contact with the inner wall of the gear 8 to be processed, so that the gear 8 to be processed can be tightly limited to prevent the gear 8 to be processed from sliding horizontally. A lifting shaft 135 is also slidably arranged at the inner center of the active cavity 132. The top ends of the two rotating support blocks 138 are rotatably sleeved on the lifting shaft 135. A top groove 133 is opened on the top surface of the column 131, and an end seat 139 is arranged in the top groove 133. The end seat 139 A screw rod 134 is welded and fixed to the bottom of 39, and the screw rod 134 passes through the inner side of the movable cavity 132 and is rotatably connected to the lifting shaft 135. Later, when the operator places the gear 8 to be processed on the top of the rotating table 13 and puts it on the column 131, the operator can use a wrench to rotate the end seat 139 clockwise to make the screw rod 134 rotate and move downward, and move the lifting shaft 135 downward. During the downward movement of the lifting shaft 135, the bottom end of the rotating support block 138 will rotate upward until the bottom end of the rotating support block 138 is tightly pressed against the inner wall of the gear 8 to be processed, so that the gear 8 to be processed can be pressed and fixed, ensuring the stability of the gear 8 to be processed during the subsequent gear hobbing process and preventing horizontal slippage.

[0027] Among them, a threaded hole is opened through the top groove 133 and the movable cavity 132, and the threaded hole corresponds to the screw rod 134, so that the screw rod 134 can be smoothly rotated and twisted, and the inner walls on both sides of the movable cavity 132 are opened with side rod grooves 136, and the two ends of the lifting shaft 135 are respectively slid in the two side rod grooves 136, so that the lifting shaft 135 can stably lift and slide in the movable cavity 132, and two rotating shafts 137 are fixed to the inner side of the movable cavity 132. The center of the rotating support block 138 is rotatably sleeved on the rotating shaft 137, so that the rotating support block 138 can smoothly rotate up or down with the lifting and lowering of the lifting shaft 135.
