Technical Field

[0001] The utility model relates to the technical field of equipment manufacturing, in particular to a rotary knife-taking device for a knife sharpener. Background Art

[0002] In the field of equipment manufacturing, CNC knife sharpeners are often used in equipment manufacturing technology. The knife sharpening racks of commonly used CNC knife sharpeners mostly use fixtures to fix the tools. During the knife sharpening process, multiple sets of tools need to be sharpened at one time according to actual usage needs. In order to ensure the tool clamping stability after changing different tools during sharpening, as well as the efficiency of tool loading and unloading, it is necessary to use automated equipment to replace the manual operation of the knife loading and unloading action, so as to improve the working efficiency of the knife sharpener. Therefore, a rotary knife removal device for the knife sharpener is needed. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a rotary knife-removing device for a knife sharpener, which is used to solve the problem of how to replace the knife in the knife sharpener in the prior art.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0005] A rotary knife-taking device for a knife sharpener, comprising:

[0006] A machine tool, wherein a tool clamping assembly is provided on the upper side of the machine tool, and a tool holder is provided on the machine tool, and a tool sharpening frame which can be raised and lowered is provided on the tool holder;

[0007] A knife taking assembly is provided on the lower side of the knife sharpening frame, and the knife taking assembly includes a knife taking base detachably connected to the knife sharpening frame, a knife seat driving member is provided on the knife taking base, a knife taking seat is provided at the movable end of the knife seat driving member, and the knife seat driving member drives the knife taking seat to rotate in the vertical direction;

[0008] The tool clamping seat is rotatably connected to the upper side of the machine tool along the horizontal direction.

[0009] To implement the above technical solution, a knife-taking assembly is provided at the lower side of the knife sharpening frame, and the lifting and lowering movement of the knife sharpening frame can be utilized to drive the knife-taking assembly to lift and lower, while the knife seat driving member drives the knife-taking seat to rotate in the vertical direction. When it is necessary to move downward to take the knife, the knife seat driving member drives the knife-taking seat to rotate in the vertical direction to a working state in which the knife-taking seat faces downward. Moreover, in this working state, the height of the lower side of the knife-taking seat is lower than that of the lower side of the knife sharpening frame. In this way, the knife-taking seat can be used to take the knife, and the knife-taking seat after taking the knife is rotated to a horizontal state, and the knife clamping seat clamps the knife. When it is necessary to sharpen the knife, the knife seat driving member drives the knife-taking seat to rotate in the vertical direction to a working state in which the knife is facing upward, thereby providing sufficient sharpening space for the sharpening working surface of the knife sharpening frame.

[0010] In one embodiment of the present invention, a material seat is provided between the bottom of the tool clamping seat and the machine tool. The material seat is connected to the machine tool in a forward and backward sliding manner. A material table is provided on one side of the material seat.

[0011] To implement the above technical solution, the material holder is connected to the machine tool by sliding it forward and backward, and the tool holder is rotated to a horizontal state after the tool is taken out, so as to send the tool clamping holder to the tool holder, clamp the tool on the tool holder, and then sharpen the tool with the sharpening rack.

[0012] In one embodiment of the present invention, a rotating drive member is provided in the material seat, a rotating table is provided on the material table, and the rotating table and the material table are slidably matched. The rotating table is provided at the movable end of the rotating drive member, and the rotating drive member drives the rotating table to rotate on the material table.

[0013] The above technical solution is implemented by setting up a sliding fit between the rotating table and the material table, and using the material table to limit the rotating table, thereby ensuring the stability of the rotating drive member driving the rotating table to rotate on the material table, thereby ensuring the stability of the tool clamping seat during the tool sharpening process.

[0014] In one embodiment of the present invention, the tool clamping seat is arranged on the upper side of the rotating table, and a tool clamping drive component is provided on the tool clamping seat, a tool clamping head is provided at the movable end of the tool clamping drive component, and the fixed end of the tool clamping drive component is detachably connected to the tool clamping seat.

[0015] By implementing the above technical solution and detachably connecting the fixed end of the tool clamping drive member to the tool clamping seat, the cooperation stability between the tool clamping drive member and the tool clamping seat can be improved, thereby ensuring the stability of the tool during the sharpening process.

[0016] In one embodiment of the present invention, a cutter head bracket is provided between the lower side of the cutter head and the rotating platform, and the cutter head bracket supports the cutter head.

[0017] To implement the above technical solution, a cutter head bracket is arranged between the lower side of the cutter head and the rotating table to support the cutter head, so that the stability of the cutter head when subjected to force can be improved. When sharpening the knife, the cutter head is subjected to greater force. Therefore, the stability of the cutter head is of great significance to the sharpening process of the tool.

[0018] In one embodiment of the present invention, a transverse driving member is provided in the tool holder, the tool sharpening frame is provided at a movable end of the transverse driving member, and the transverse driving member drives the tool sharpening frame to move in the transverse direction.

[0019] To implement the above technical solution, the lateral drive member can be used to drive the sharpening rack to move in the lateral direction, thereby completing the switching action of the tool to be sharpened.

[0020] In one embodiment of the present invention, a transverse guide rail is further provided in the tool holder, and the tool sharpening holder is slidably engaged with the transverse guide rail.

[0021] To implement the above technical solution, the lateral movement of the knife sharpening frame can be limited by providing a lateral movement guide rail, thereby ensuring the stability and accuracy of the lateral movement of the knife sharpening frame.

[0022] When the knife needs to be sharpened, the knife seat driving member drives the knife seat to rotate in the vertical direction to the working state where the knife seat is facing downward, thereby providing sufficient sharpening space for the sharpening working surface of the knife frame.
