Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathe equipment, in particular to a tool holder pin extraction mechanism for a numerically controlled lathe. Background Art

[0002] The tool holder pin puller mechanism of CNC lathe is a device used to quickly change tools in CNC lathes. Its main purpose is to improve production efficiency and processing accuracy. The following is some basic introduction and working principle of the tool holder pin puller mechanism of CNC lathe.

[0003] Basic introduction:

[0004] In CNC lathes, the tool holder is the part where the tool is installed, and the tool holder pin mechanism is used to fix or release the tool holder so that the tool can be quickly replaced when needed. This mechanism is usually designed to be very precise and stable to ensure accuracy and repeatability during processing.

[0005] Working principle:

[0006] 1. Pinning operation: When the tool needs to be replaced, the operator will issue a command through the CNC system to activate the pinning mechanism. The pinning mechanism usually includes one or more hydraulically or pneumatically driven pins that can be inserted or withdrawn from the locking hole between the tool holder and the turret (tool holder).

[0007] 2. Locking and unlocking: When inserted, the pull pin locks the tool holder in a predetermined position, ensuring the stability and accuracy of the tool position during processing. When the tool needs to be changed, the pull pin will be withdrawn, releasing the tool holder, and the operator or automatic tool changer can remove the old tool and install the new one.

[0008] 3. Automatic tool change: In more advanced CNC lathes, the tool holder pin puller mechanism is often used in conjunction with the automatic tool change system (ATC) to achieve fully automated tool change, greatly improving processing efficiency and precision.

[0009] Key Benefits:

[0010] Improved productivity: Tool changes reduce machine downtime.

[0011] Improve machining accuracy: ensure repositioning accuracy after each tool change and reduce errors.

[0012] Reduce labor intensity: Automatic tool changing reduces the operator's physical labor.

[0013] Maintenance and precautions:

[0014] Check the hydraulic or pneumatic system of the pin puller regularly to ensure there are no leaks and that adequate pressure is maintained.

[0015] Ensure that the puller pin and its drive mechanism are clean to avoid accumulation of dust and swarf that could cause mechanical failure.

[0016] Lubricate and maintain the pin puller mechanism regularly to keep it in good working condition and extend its service life.

[0017] In short, the tool holder pin extraction mechanism is a key component of the CNC lathe, which plays a vital role in improving production efficiency and processing quality. Proper maintenance and operation can ensure the efficient and stable operation of the mechanism.

[0018] However, the device cannot guarantee quick installation when in use.

[0019] Therefore, in view of this, the existing deficiencies are studied and improved, and a tool holder pin extraction mechanism for a CNC lathe is proposed. Utility Model Content

[0024] Furthermore, a magnetic attraction layer is provided on the surface of the stop block, so that the stop block can easily attract the outside of the external connection device.

[0025] Furthermore, an elastic connection is formed between the spring rod and the embedded block, which facilitates the contraction of the spring rod.

[0026] Furthermore, the thickness of the stop block is greater than the original length of the spring rod, so as to prevent the stop block from being too short and entering the inner side of the embedded block.

[0027] Furthermore, the auxiliary structure includes a first telescopic component, a splint, a second telescopic component and an embedded shaft. The bottom end of the bottom groove is provided with an embedded shaft, the bottom end of the embedded shaft is provided with a splint, the outer side of the splint is provided with a first telescopic component, one end of the first telescopic component is provided with a second telescopic component, and a telescopic structure is formed between the second telescopic component and the first telescopic component to facilitate the left and right movement of the splint.

[0028] Furthermore, the inner diameter of the embedded shaft is larger than the width of the clamping plate, so that the embedded shaft can be clamped on the outer side of the clamping plate.

[0029] Compared with the prior art, the beneficial effects of the utility model are:

[0030] 1. The utility model inserts the external connection device into the inner side of the card position piece, and the spring rod and the stop block on the inner side of the embedded block are squeezed and recovered by the external connection device, and the stop block is set against one side of the external connection device, so that when the external connection device is connected with the transmission component, the pin-pulling base, etc., the more complicated installation steps are omitted;

At this time, the clamping plate inside the embedded shaft is separated by pressure, and the structure formed between the second telescopic assembly and the first telescopic assembly helps the clamping plate reduce the pressure it receives, so that the area formed between the clamping plate and the embedded shaft can stabilize the bottom end of the knife assembly.

[0042] 1. Quick connection and disassembly: Through the mechanism of the combination of the spring rod 802 and the stop block 801, the external connection device 3 can be quickly inserted and fixed in the locking piece 9, and when disassembly is required, such a structure can also quickly release the connection device, making the connection and disassembly process more convenient and efficient.

[0043] 2. Reduce component wear: The spring rod 802 provides the necessary elasticity and pressure, so that during the connection and disassembly process, the block 801 can effectively absorb and relieve external forces, reducing component wear caused by direct hard contact.

[0044] 3. Improve structural stability: The abutment block 801 is tightly pressed against one side of the external connection device 3, which increases the stability of the overall structure and avoids loosening due to vibration or external force during use.
