Technical Field

[0001] The utility model relates to the technical field of grooving tool adjustment, and particularly relates to a grooving tool with a large cutting depth that is convenient for adjustment. Background Art

[0002] A grooving tool is a tool used for cutting materials such as metal and wood to make grooves or slots. It usually has a blade with a relatively long cutting edge and can cut straight or curved grooves on a workpiece. Grooving tools are mainly used in woodworking, metal processing and other manufacturing fields and have a wide range of uses. The operation mode of the grooving tool can be manual operation or automatic cutting through mechanical equipment. In industrial production, the grooving tool can be used in conjunction with other tools and equipment, such as milling machines and lathes, to achieve efficient processing production.

[0003] Currently, for the grooving tool installed on the milling machine spindle, the surface of the spindle is equipped with an annular base, and at the end of the spindle, a threaded cap is used to firmly clamp the grooving tool. However, whenever it is necessary to replace it with a thinner grooving tool, the staff needs to replace the matching new cap to ensure the stable clamping of the grooving tool. Therefore, it is rather troublesome and the applicability is insufficient, which needs to be improved. Content of the Utility Model

[0004] (I) Technical Problems to be Solved

[0005] Aiming at the deficiencies of the prior art, the utility model provides a grooving tool with a large cutting depth that is convenient for adjustment, and solves the technical problem of insufficient applicability of the existing spindle.

By inserting the tip of a cross screwdriver into the inside of the lead screw and rotating it, the lead screw rotates and engages in a threaded drive with the top ring. As a result, the top ring drives the limit ring to slide upward inside the ring-shaped part, respectively, within the ring groove and the limit groove. The top ring will lift the lower surface of the grooving tool body until the top ring and the cap clamp the grooving tool body, at which point the rotation of the lead screw can be stopped. Thus, the grooving tool body of any thickness can be tightened without replacing the cap, thereby improving the practicality and applicability. Additionally, by optimizing the structure and layout of the adjustment mechanism, the adjustment mechanism is simple to operate and can be conveniently installed additionally on the existing end of the main shaft, facilitating promotion and having strong practicality.

[0024] Embodiment

[0025] As Figures 1 - 5 shown, the technical solution in the embodiment of the present application effectively solves the technical problem of insufficient applicability of the existing main shaft. The general idea is as follows:

[0026] In view of the problems existing in the prior art, the present utility model provides an easily adjustable grooving tool with a large depth of cut, which includes a connecting main shaft 11, and a main shaft end head 12 is provided at the upper end of the connecting main shaft 11;

[0027] An adjustment mechanism is fixedly installed on the circumferential surface of the main shaft end head 12;

[0028] The adjusting mechanism includes an annular member 18. An annular groove 19 is provided inside the annular member 18. A limiting groove 21 is provided on the side wall of the annular groove 19. A rotating groove 22 is provided on the inner wall of the annular groove 19. A counterbore 23 is provided on the inner wall of the rotating groove 22. A lead screw 24 is rotatably installed inside the rotating groove 22. The cross head of the lead screw 24 is located inside the counterbore 23. A top ring 25 is slidably installed inside the limiting groove 21. A limiting ring 26 is fixedly installed on the inner side of the top ring 25. The limiting ring 26 is located inside the limiting groove 21 and is slidably installed with the limiting groove 21. By inserting the tip of a cross screwdriver into the lead screw 24 and rotating it, the lead screw 24 rotates and engages in a threaded drive with the top ring 25. Then, the top ring 25 drives the limiting ring 26 to slide upward inside the annular member 18, inside the annular groove 19 and the limiting groove 21 respectively. The top ring 25 will lift the lower surface of the grooving tool body 17 until the top ring 25 and the cap 14 clamp the grooving tool body 17, and then the rotation of the lead screw 24 can be stopped. Thus, the grooving tool body 17 with any thickness can be tightened without replacing the cap 14, thereby improving the practicability and applicability.

[0029] The lead screw 24 is threadedly installed with the limiting ring 26. The limiting ring 26 is in contact with the lower end of the grooving tool body 17. A threaded groove 13 is provided inside the spindle end head 12. A cap 14 is snap-fitted on the upper end of the spindle end head 12. A stepped groove 15 is provided through the cap 14. A screw 16 is threadedly installed between the stepped groove 15 and the threaded groove 13. The grooving tool body 17 is slidably installed on the circumferential surface of the spindle end head 12. The grooving tool body 17 is in contact with the lower end of the cap 14. When it is necessary to replace a thinner grooving tool body on the spindle end head 12, the staff can first use a cross screwdriver to remove the screw 16. Then, the staff can take out the cap 14 and directly take out the grooving tool body 17. After the grooving tool body 17 is taken out, at this time, the staff can directly place the grooving tool body 17 to be replaced on the spindle end head 12 of the connecting spindle 11. At this time, the grooving tool body 17 will slide down to the limiting ring 26 due to the action of gravity. Then, the staff can install the cap 14 on the spindle end head 12 again and screw the screw 16 into the stepped groove 15 and the threaded groove 13.

[0030] Working principle:

[0031] First step, when it is necessary to replace the thinner grooving tool body 17 on the spindle end head 12, the staff can first use a cross screwdriver to remove the screw 16. Subsequently, the staff can take out the cap 14 and directly remove the grooving tool body 17. After the removal of the grooving tool body 17 is completed, at this time, the staff can directly place the grooving tool body 17 to be replaced on the spindle end head 12 connecting the spindle 11. At this time, the grooving tool body 17 will slide down to the limiting ring 26 due to the action of gravity. Subsequently, the staff can install the cap 14 on the spindle end head 12 again and screw the screw 16 into the stepped groove 15 and the threaded groove 13;

[0032] Second step, since the replaced grooving tool body 17 is thinner than the original one, there will be a certain gap between the grooving tool body 17 and the lower surface of the cap 14. At this time, the staff can insert the tip of the cross screwdriver into the screw rod 24 and rotate it, so that the screw rod 24 rotates and engages in a screw drive with the top ring 25. As a result, the top ring 25 drives the limiting ring 26 to slide upward in the annular groove 19 and the limiting groove 21 inside the annular part 18 respectively. The top ring 25 will jack up the lower surface of the grooving tool body 17 until the limiting ring 26 and the cap 14 clamp the grooving tool body 17, and then the rotation of the screw rod 24 can be stopped.

[0033] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present invention.
