Technical Field

The utility model relates to the technical field of tool handle assembly, in particular to a CNC tool handle assembly device.

Background Art

CNC machining usually refers to computer digital controlled precision machining. The tool handle is mainly used to connect the mechanical spindle and the tool in CNC machining. The tool handle includes a rivet, a tool handle body (also known as a tool handle) and a collet. One end of the rivet is connected to the machine tool bayonet, and the other end of the rivet is threadedly connected to one end of the tool handle body. The collet is threadedly connected to the other end of the tool handle body through the collet screw and can be used to clamp the tool.

At present, the assembly of the rivet, the tool handle body and the collet is mostly done manually. The tool is placed in the collet manually, and then the collet is placed in the tool handle. The length of the tool head is aligned with the length positioning fixture, and then the collet screw is turned by an electric screwdriver to complete the installation between the collet and the tool handle body. Finally, the rivet is locked to the end of the tool handle body manually.

However, after the extension length of the tool head is determined by the length positioning jig, manually locking the collet and the tool handle body may cause the tool to shake or cause the tool head extension length error due to inconsistent locking force, thereby affecting the CNC processing quality. In addition, when manually assembling the rivet, tool handle body and collet, the labor intensity of the staff is high and the efficiency is low.

Therefore, the above problems need to be solved urgently.

In addition, the terms "first" and "second" are only used to distinguish in the description and have no special meaning.

At present, the assembly of the rivet, the tool handle body and the collet is mostly done manually. The tool is placed in the collet manually, and then the collet is placed in the tool handle. The length of the tool head is aligned with the length positioning fixture, and then the collet screw is turned by an electric screwdriver to complete the installation between the collet and the tool handle body. Finally, the rivet is manually locked to the end of the tool handle body. However, after the extension length of the tool head is determined by the length positioning fixture, when the collet and the tool handle body are manually locked, the tool may shake or the tool head extension length error may occur due to inconsistent locking force, thereby affecting the CNC processing quality. In addition, when the rivet, the tool handle body and the collet are manually assembled, the labor intensity of the staff is high and the efficiency is low.

Therefore, when assembling the rivet, the tool handle body and the collet, a limit assembly needs to be added to prevent the tool from shaking, thereby affecting the assembly quality.

Based on the above, please refer to Figures 1 to 4. In this embodiment, a CNC tool handle assembly device is proposed, which is used to assemble a rivet 300, a tool handle body 100 and a collet 200 with a tool. The CNC tool handle assembly device includes a tool handle fixture 1, a moving component 2, a length detection component 3, a limit component 4, a push component 5, a collet locking component 6 and a rivet installation component 7. The tool handle fixture 1 is used to fix the tool handle body 100 with the collet 200 installed; the tool handle fixture 1 is arranged at the moving end of the moving component 2, and the moving component 2 is configured to drive the tool handle fixture 1 to move along a preset path; the length detection component 3 is arranged at an initial position in the preset path, and is configured to detect the tool The length of the tool; the limit assembly 4 is arranged on the downstream side of the length detection member 3 in the preset path; the moving end of the push assembly 5 is connected to the limit assembly 4, and the push assembly 5 is electrically connected to the length detection member 3, and the push assembly 5 is configured to push the limit assembly 4 according to the length of the tool until it abuts against the tool and the collet 200; the collet locking assembly 6 is arranged opposite to the limit assembly 4 and is located on both sides of the tool handle fixture 1, and the collet locking assembly 6 is configured to lock the collet 200 and the tool; the rivet installation assembly 7 is arranged on the downstream side of the limit assembly 4 in the preset path, and the rivet installation assembly 7 is configured to install the rivet 300 on the end of the tool handle body 100 away from the collet 200. In this embodiment, the length detection member 3 is a length sensor, and the length sensor and its use are both existing technical means, which will not be described in detail here.

It can be understood that the tool handle body 100 is fixed to the tool handle fixture 1, and then the length of the tool is detected by using the length detection member 3, and the detection result is fed back to the pushing component 5. The pushing component 5 pushes the limiting component 4 according to the detection result, so that the limiting component 4 limits the collet 200 and the tool, thereby preventing the collet 200 or the tool from shaking when the collet locking component 6 locks the collet 200, thereby improving the assembly efficiency between the tool handle body 100 and the collet 200. After the tool handle body 100 and the collet 200 are assembled, the tool handle fixture 1 is moved to the rivet installation component 7 under the action of the moving component 2. Under the action of the rivet installation component 7, the assembly between the rivet 300 and the tool handle body 100 can be completed. In the assembly process of the collet 200, the tool handle body 100 and the rivet 300, manual participation can be reduced, thereby reducing the labor intensity of the staff and improving the assembly efficiency.

In actual application, the position of the length detection member 3 is the first working position, the position of the limit assembly 4, the push assembly 5 and the collet locking assembly 6 is the second working position, and the position of the rivet installation assembly 7 is the third working position. Before assembly, the staff first installs the tool on the collet 200, then preliminarily installs the collet 200 with the tool on the handle body 100, and then fixes the handle body 100 on the handle fixture 1. Under the action of the moving assembly 2, the handle fixture 1 is moved to the first working position, and the length of the tool is detected by the length detection member 3. Then, under the action of the moving assembly 2, it is moved to the second working position. The push assembly 5 pushes the limit assembly 4 to approach the handle fixture 1 according to the length of the tool detected by the length detection member 3, and the limit assembly 4 can limit the collet 200 and the tool to prevent the collet 200 and the tool from shaking when the collet locking assembly 6 assembles the collet 200 and the handle body 100. After the assembly between the collet 200 and the handle body 100 is completed, the handle fixture 1 can be transferred from the second working position to the third working position under the action of the moving assembly 2. When the handle fixture 1 is in the third working position, the rivet 300 is assembled to the handle body 100 through the rivet installation assembly 7. After the collet 200, the handle body 100 and the rivet 300 are assembled, the handle fixture 1 can be moved to the unloading station under the action of the moving assembly 2, and the staff will remove the assembled handle, and then the moving assembly 2 drives the handle fixture 1 to repeat the above path.
