Description

Technical Field

[0001] The utility model relates to the technical field of tool turrets, in particular to a milling shaft structure of a tool turret. Background Art

[0002] The tool turret is a crucial component of a CNC lathe, responsible for mounting and positioning cutting tools to enable automated workpiece machining. It primarily consists of a turret body, toolholder, transmission mechanism, and locking mechanism. Overtime use of traditional tool turrets can lead to wear between indexing plates A and B, which can increase the clearance between the toolholders. This can cause the toolholder to wobble or lift outward during rotation or under cutting forces, potentially interfering with the driven toolholder and the milling spindle angle head gear. This clearance can also affect the toolholder's stability and accuracy. Utility Model Content

[0005] Furthermore, in order to facilitate the extension of the rotating gear shaft, an opening is provided on the side wall of the retaining ring, one end of the rotating gear shaft passes through the opening, and the end of the rotating gear shaft protrudes from the side wall of the retaining ring.

[0006] Furthermore, to ensure the retaining ring presses against the power tool holder and prevent interference between the rotating gear shaft and the power tool holder, the rotating gear shaft protrudes 0.05mm from the retaining ring sidewall. This ensures that the retaining ring's outer diameter is just large enough to press against the power tool holder and also allows for angle adjustment of the rotating gear shaft.

[0007] Furthermore, one end of the rotating gear shaft protruding from the retaining ring is provided with a fork-shaped portion, and a socket is provided on the fork-shaped portion. When adjusting the angle, the end of the corresponding power tool seat is inserted into the socket, and the power tool seat is driven to rotate by the rotation of the rotating gear shaft, thereby realizing the adjustment of the power tool seat angle.

[0008] Furthermore, the angle adjustment assembly also includes a bevel gear, a gear transmission shaft and an angle motor, the bevel gear is arranged at the front end of the gear transmission shaft, the rear end of the gear transmission shaft is connected to the angle motor, a second bearing is provided on the outside of the bevel gear, and it is rotatably connected to the milling shaft angle head through the second bearing, and the front end tooth surface of the bevel gear is meshed with the rotating gear shaft. The angle motor drives the bevel gear to rotate through the gear transmission shaft, and the bevel gear is meshed with the rotating gear shaft, driving the rotating gear shaft to rotate.

[0009] Furthermore, the turret box is also provided with a dividing plate A, a dividing plate B and a sleeve. The sleeve is arranged on the outside of the gear transmission shaft, and the dividing plate B is coaxially arranged on the outside of the sleeve and connected to the turret body. The dividing plate A is arranged on the outside of the dividing plate B. The outside of the dividing plate A is provided with a transmission tooth surface, and the transmission tooth surface of the dividing plate A is connected to the driving gear on the output shaft of the turret motor through an intermediate transmission gear pair.

[0010] Furthermore, a coupling is included, and the gear transmission shaft and the angle motor are connected to each other through the coupling. The coupling connection can reduce the influence of coaxial error during assembly.

[0011] Preferably, the bevel gear is a 90° double bevel gear.

[0012] The beneficial effects of the present invention are as follows: the milling shaft structure of the turret provided by the present invention effectively blocks the power tool holder when the turret is lifted by adding a retaining ring, so that it runs in a fixed position, avoiding the power tool holder from lifting outward, thereby preventing mutual interference between components; the retaining ring limits the position of the power tool holder, avoiding the power tool holder from being affected by the wear between the dividing plate A and the dividing plate B, thereby ensuring the stability and accuracy of the turret.

[0031] like Figure 7 and Figure 8 As shown, the retaining ring 10 is generally in the shape of a hollow straw hat, with an opening 10.1 provided on the side wall of the retaining ring 10. One end of the rotating gear shaft 12 passes through the opening 10.1, and the end of the rotating gear shaft 12 protrudes from the side wall of the retaining ring 10.

[0034] Working principle:

[0035] The turret mechanism in this embodiment is a traditional ordinary turret with an additional rotating shaft added inside, referred to as a power turret. Its structural principle is that the angle adjustment component adopts an internal direct drive motor - angle motor 4, which reduces the transmission mechanism, and cooperates with the milling axis angle head 5 and the power tool holder 3 to realize the milling function on the traditional lathe. Among them, the milling angle head is an important structure, and its interior is a 90° double bevel gear 8, which well guarantees accuracy and rigidity. A retaining ring 10 is designed and installed on the housing of the milling axis angle head 5, which can effectively avoid mechanical wear caused by long-term operation, resulting in interference between the power tool holder 3 and the rotating gear shaft 12, and the outward lifting of the power tool holder 3.
