[0044] Furthermore, the card plate 7 includes a transverse positioning plate 7-1 and a longitudinal indicator plate 7-2. A card slot 7-3 is provided at one end of the transverse positioning plate 7-1. The central angle of the card slot 7-3 is greater than 180°. The transverse positioning plate 7-1 is mounted on the annular groove 5 of the limit block 4 by means of the card slot 7-3. The parts of the transverse positioning plate 7-1 located on both sides of the card slot 7-3 are close to or away from each other. The longitudinal indicator plate 7-2 is arranged below the end of the transverse positioning plate 7-1 away from the card slot 7-3. The inner wall of the longitudinal indicator plate 7-2 contacts the scale surface of the scale 6. Figure 3 , Figure 4 and Figure 5 As shown, during installation, the parts of the transverse positioning plate 7-1 located on the upper and lower sides of the card slot 7-3 are moved away, and then the transverse positioning plate 7-1 is put onto the limit block 4 and the transverse positioning plate 7-1 is located at the annular groove 5. When the limit block 4 is rotated, the limit block 4 will drive the card plate 7 to move along the length direction of the guide rod 3. When not in use, the card plate 7 can be removed. The structure is simple and easy to disassemble and assemble.

[0045] Furthermore, it also includes a rotating disk 8 and a rotating drive mechanism 9, wherein the rotating disk 8 is rotatably arranged above the slide seat 2; an upper slide groove 10 is provided on the upper end surface of the base 1, and a lower slide groove 11 is provided on the base 1, wherein the lower end of the upper slide groove 10 is connected to the lower slide groove 11, and the rotating drive mechanism 9 is slidably arranged in the lower slide groove 11, and the output shaft of the rotating drive mechanism 9 passes through the upper slide groove 10 and the slide seat 2 and then is connected to the rotating disk 8.

The open end of the lower chute 11 is sealed by the first sealing plate 12, and the part of the upper chute 10 located on the right side of the slide seat 2 is sealed by the second sealing plate 13, which can reduce the probability of dust, debris, etc. entering the upper chute 10 and the lower chute 11. By increasing the length of the slide seat 2 located on the left side of the rotation drive mechanism 9, the slide seat 2 can cover the part of the upper chute 10 located on the left side of the rotation drive mechanism 9.

[0047] Furthermore, it also includes a shielding plate 14, which is arranged above the first sealing plate 12, and the second sealing plate 13 is located between the shielding plate 14 and the slide seat 2.

[0048] Furthermore, the lower end of the shielding plate 14 is plugged into the first sealing plate 12. When the position of the slide 2 needs to be moved, the shielding plate 14 is removed, and then the second sealing plate 13 is removed, and after adjusting the position of the slide 2, the second sealing plate 13 of a suitable length is installed, and finally the shielding plate 14 is inserted into the first sealing plate 12, without disassembling the first sealing plate 12, which is simpler and more convenient.

[0049] Furthermore, it also includes an insertion strip 15, which is arranged on both sides of the second sealing plate 13, and a slot is arranged on the groove wall of the upper slide groove 10, and the insertion strip 15 is plugged into the slot, and the slot is located on the inner side of the shielding plate 14. The insertion strip 15 cooperates with the slot to realize the connection between the second sealing plate 13 and the base 1, which has a simple structure, is convenient and quick to disassemble and assemble, saves time and effort, and the shielding plate 14 shields the second sealing plate 13, the insertion strip 15 and the slot, making the appearance more neat and beautiful.

[0050] Furthermore, a vertical dovetail strip 16 is provided on the inner wall of the first sealing plate 12, and a vertical dovetail groove is provided on the outer wall of the base 1. The upper end surface of the vertical dovetail groove is flush with the upper end surface of the base 1, and the height of the vertical dovetail groove is less than the height of the base 1. The vertical dovetail strip 16 is plugged into the vertical dovetail groove. Figure 8As shown, the first sealing plate 12 can be installed on the base 1 by inserting the vertical dovetail strip 16 into the vertical dovetail groove from top to bottom. The structure is simple, the connection is firm and reliable, and the assembly and disassembly is convenient and fast, saving time and effort.

[0051] Furthermore, it also includes a deflector 17, which is arranged above the second sealing plate 13, the lower end surface width of the deflector 17 is greater than the width of the upper slide 10, the lower end surface of the deflector 17 contacts the upper end surface of the base 1, and the height of the deflector 17 gradually decreases from the middle to both sides along the width direction of the upper slide 10. Figure 8 and Fig. 9 As shown, the left and right sides of the air deflector 17 are tilted downward, so that dust, debris, etc. that fall onto the air deflector 17 will slide onto the base 1 on both sides of the air deflector 17, avoiding entering the interior of the base 1 through the gap between the second sealing plate 13 and the base 1, thereby achieving a better sealing effect.

[0052] Furthermore, a gap is left between the limit block 4 and the upper end surface of the base 1, so as to avoid friction caused by direct contact between the limit block 4 and the base 1 when the limit block 4 is rotated, thereby saving more effort.

[0053] In this embodiment, the length direction of the left and right guide rods 3 is arranged along the front-back direction, and each guide rod 3 is threadedly connected with two front and rear limit blocks 4, and an annular groove 5 is provided on the left and right limit blocks 4 at the rear end, and a clamping plate 7 is provided in the annular groove 5, and a scale 6 is provided on the left and right walls of the base 1, and the slide 2 can move forward and backward along the guide rods 3. A sink groove is provided on the side wall of the base 1, and the first sealing plate 12 is arranged in the sink groove, so that the surface of the base 1 is flat.

[0054] The gear milling machine further includes a lifting mechanism 18 and a milling cutter 19. The lifting mechanism 18 is hoisted above the base 1 and located on the left side of the slide 2. The milling cutter 19 is arranged below the lifting mechanism 18. The milling cutter 19 contacts or separates from the workpiece 20 to be processed on the rotating disk 8 by means of the extension and retraction of the lifting mechanism 18. Figure 1 As shown, the lifting mechanism 18 extends to push the milling cutter 19 down, so that the milling cutter 19 processes the workpiece 20. When the diameter of the workpiece 20 changes, the distance that the slide 2 needs to move can be determined based on the diameter difference between the two workpieces 20, and then the limit block 4 is moved. In the process of moving the limit block 4, the clamping plate 7 moves along the scale 6, and the moving distance can be checked at all times through the scale surface on the scale 6. When the clamping plate 7 moves into place, it means that the limit block 4 also moves into place, and then the two limit blocks 4 can be used to clamp the slide 2. The structure is simple, the adjustment is convenient and quick, and it saves time and effort.

[0055] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
