DETAILED DESCRIPTION

[0023] A specific implementation of the present utility model is described in detail below in conjunction with the accompanying drawings, but it should be understood that the protection scope of the present utility model is not limited by the specific implementation mode.

[0024] Embodiment 1:

[0025] like Figure 1-5 As shown, an automatic tool sharpening machine provided by the embodiment of the utility model comprises a chassis 1, a sharpening mechanism, a tool positioning mechanism, a tool fixing mechanism, and a tool feeding mechanism.

[0026] The tool positioning mechanism includes a movable lever 21 and an induction switch 22 for sensing the position of the movable lever 21. The movable lever 21 is hingedly connected to the Y-axis reciprocating mechanism 31. The movable lever 21 can swing through the hinged connection and is driven to reciprocate along the Y-axis through the Y-axis reciprocating mechanism 31. The end of the movable lever 21 close to the tool fixing mechanism is the tool contact end 23.

[0027] Specifically, the grinding mechanism includes a Y-axial reciprocating mechanism 31 and an electric grinder 32. The electric grinder 32 is driven by the Y-axial reciprocating mechanism 31 to reciprocate along the Y-axial direction. The Y-axial reciprocating mechanism 31 is a Y-axial electric slide. The electric grinder 32 is fixed on the Y-axial slide seat 33 of the Y-axial electric slide. The movable lever 21 is hingedly connected to the Y-axial slide seat 33 through a hinge seat assembly. The induction switch 22 is fixed on the Y-axial slide seat 33. The induction switch 22 can be set below the other end of the movable lever 21. The induction switch 22 can be a proximity switch.

[0028] Specifically, the articulated seat assembly includes a limit slot 24, a connecting plate 25 and a hinge shaft 26. The opening of the limit slot 24 is upward. The movable lever 21 is close to one end of the tool fixing mechanism through the limit slot 24 and is hingedly connected through the hinge shaft 26. The connecting plate 25 stabilizes the limit slot 24 on the Y-axis slide 33. The tool contact end 23 is a contact plate arranged above this end of the movable lever 21.

[0029] Preferably, the tool fixing mechanism includes a rotary body 41 and a tool chuck 42. The rotary body 41 is connected to a dividing mechanism, and dividing is performed through the dividing mechanism.

[0030] Specifically, the tool fixing mechanism is a pneumatic spring chuck mechanism, the tool chuck 42 is a spring chuck, which is connected to the pneumatic component 43, and the indexing mechanism includes an indexing servo motor 51 and a transmission belt 52. The indexing servo motor 51 drives the rotating body 41 to index through the transmission belt 52, and the transmission belt 52 is a synchronous belt.

[0031] Specifically, the tool feeding mechanism drives the tool fixing mechanism to realize the feeding of the tool, which includes an X-axis electric slide 61 , and the tool fixing mechanism is fixed on an X-axis slide seat 62 of the X-axis electric slide 61 .

[0032] In some instances, the X-axis electric slide 61 includes a vertical motor 63 and a rack 64. The vertical motor 63 is fixed on the X-axis slide 62. The rack 64 is fixed on the slide rail 65 of the X-axis electric slide 61 or on the chassis 1. The output end of the vertical motor 63 is provided with a gear 66 meshing with the rack 64. The transmission design of the vertical motor 63 and the rack 64 reduces the volume of the product to a certain extent, and the space design is more reasonable.

[0033] The working principle of the utility model is as follows: the movable lever 21 is driven by the Y-axis reciprocating mechanism 31 to move toward the tool fixing mechanism, that is, to drive it to move toward the tool. After the front end contact plate contacts one of the blades of the tool, the front end of the movable lever 21 will be slightly tilted, and the other end of the movable lever 21 will approach the sensing switch 22. The sensing switch 22 receives the signal and transmits it to the control system. The control system controls the Y-axis reciprocating mechanism 31 to stop running, and records the tool position, that is, the tool processing position, and controls the Y-axis reciprocating mechanism 31 to return. Corresponding processing can be performed according to the program setting. If the tool has multiple blades, it can be automatically indexed by the indexing mechanism, that is, the entire processing can be completed with one clamping.

[0034] The above disclosures are only several specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
