Description

Technical Field

[0001] The utility model relates to the technical field of locking structures, in particular to a tool holder locking structure for combined turning and milling. Background Art

[0002] Machine tools refer to mechanical equipment that processes workpieces. With the continuous development of modern mechanical equipment and the continuous improvement of precision, the precision requirements for the parts of assembled mechanical equipment are also constantly increasing. High-precision parts processing often requires multiple machine tools to perform composite processing. The cutter head is a consumable part on the machine tool. The processing of large quantities of parts requires frequent maintenance of the cutter head.

[0003] The existing lathe and milling machine power tool holder tool holder generally uses key positioning and screw fixing to fix the tool head. It is very inconvenient to replace the tool and it needs to be realigned after replacement, which affects the processing efficiency. It cannot meet the requirements of rapid replacement of multiple tools in machine tools during turning and milling combined processing. Therefore, a tool holder locking structure for turning and milling combined is proposed. Utility Model Content

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a tool holder locking structure for combined turning and milling, which facilitates the removal and fixation of the tool handle, improves the tool changing efficiency and thus the processing efficiency, and is conducive to improving the practicability of the device.

[0005] To solve the above technical problems, the utility model provides the following technical solutions: a tool holder locking structure for combined turning and milling, comprising a tool holder shell, a first cavity and a second cavity are provided in the tool holder shell, the first cavity and the second cavity are connected, an axial hole is provided at the top of the tool holder shell on one side of the second cavity, the axial hole is connected with the second cavity, a tool holder interface is fixedly installed on the tool holder shell near the first cavity, a locking rod is passed through the first cavity and the second cavity, an eccentric shaft is passed through the axial hole, the eccentric shaft is connected to the locking rod for transmission, a claw sleeve is abutted between the inner wall of the first cavity near the second cavity and the tool holder interface, a limiting claw is clamped in the claw sleeve, the limiting claw sleeve is arranged on the surface of the locking rod, and a spring is abutted between the locking rod and the claw sleeve.

[0006] Preferably, a square groove is formed on one side of the locking rod located in the second cavity and passes through it from top to bottom, an integrally formed stopper is provided on the locking rod, and a top block is provided on one end of the locking rod located in the first cavity.

[0007] Preferably, the eccentric shaft includes an integrally formed rotating shaft, a convex shaft, and an adjusting seat, and the convex shaft is located in the square groove.

[0008] Preferably, a limiting groove and an adjusting hole are provided on the top of the adjusting seat, and the limiting groove has an angle of 210°.

[0009] Preferably, a limiting hole is provided at the top of the tool holder housing on one side of the axial hole, the limiting hole is communicated with the axial hole, a limiting block is fixedly installed in the limiting hole, and the limiting block is movably abutted against both sides of the limiting groove.

[0010] Preferably, a groove is formed on the claw sleeve, a baffle is provided on the side of the claw sleeve close to the stopper, the spring abuts between the stopper and the baffle, and a ridge is formed on the limiting claw, which is engaged in the groove.

[0011] Preferably, the limiting claw is movably abutted against the top block, and a clamping block is provided on the top of one side where the limiting claw abuts against the top block.

[0012] Preferably, the tool handle interface is a CAPTO tool handle interface.

[0013] The working principle of the tool lock structure of the tool holder for turning and milling compound of the utility model is as follows: the cam on the eccentric shaft is located in the square groove, and the rotation of the cam drives the locking rod to move. When moving backward, the top block on the locking rod pushes the limit claw to expand outward, so that the card block enters the keyway of the tool handle to lock the tool handle. When dismantling, the cam is rotated in the opposite direction, and the cam pushes the locking rod to move forward. The spring compresses and squeezes the claw sleeve, so that the limit claw contracts the card block to disengage from the keyway of the tool handle, and the tool handle is released to complete the replacement of the tool head. The tool handle interface adopts the CAPTO tool handle interface, which makes it more convenient and quick to replace the tool, and has high repeated positioning accuracy, further reduces the difficulty of tool changing, thereby improving the tool changing efficiency, and sets the angle of the limit groove to 210° to prevent the eccentric shaft from rotating too much and the locking rod from resetting and rebounding. The angle limitation makes the fixation of the tool head more stable.

[0014] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0015] 1. The locking rod is driven to move by the eccentric shaft, and the locking rod movement drives the limit claw to move, so as to fix and remove the cutter head placed in the cutter handle interface. The disassembly and assembly method is simple, and the fixing structure is stable and reliable, which greatly improves the tool changing efficiency and is conducive to improving the practicality of the device.

[0016] 2. Set the tool holder interface to the CAPTO tool holder interface. The CAPOT interface has good rigidity, makes tool replacement easier, has high repeat positioning accuracy, and further improves tool change efficiency. BRIEF DESCRIPTION OF THE DRAWINGS
