Problems solved by technology

For manufacturers of CNC machining centers, the T-shaped ram spindle is an outsourced part, and the cost of the spindle with the cutter cylinder device is nearly 10,000 yuan higher than the spindle without the cutter cylinder structure.
However, the T-shaped ram spindle with its own cutter cylinder is prone to hydraulic oil leakage. Once the hydraulic oil leaks, the leaked hydraulic oil will directly enter the spindle bearing, causing the bearing to burn out.
Therefore, the existing T-shaped ram spindle has certain deficiencies in terms of cost and safety of use.

Embodiment 1

[0025] Embodiment 1: The cylinder knife-beating mechanism of T-type ram main shaft, such as figure 1 and figure 2 As shown, the cylinder knife mechanism includes a cylinder 1, a lever 2, a support ring 3 and two cylindrical roller bearings 4. The cylinder 1 is purchased from SMC Company, and a solenoid valve (not shown in the figure) is arranged in the cylinder 1. The bottom of the cylinder 1 is provided with a cylinder piston 11, and the cylinder 1 is arranged on the outside of a T-shaped ram 51 whose model is BT50. On the outer wall of one side of the T-shaped ram 51, one end of the lever 2 is connected with the cylinder piston 11 through a pin 21, and the other end of the lever 2 is connected with a second fixed bracket 23 through a pin 22, and the second fixed bracket 23 is fixed. On the inner wall of the other side of the T-shaped ram 51, the lever 2 is provided with a longitudinal through hole 24, which is close to the connection between the lever 2 and the inner wall ...

Embodiment 2

[0026] Embodiment 2: The structure of the cylinder knife punching mechanism of the T-type ram main shaft of Embodiment 1 is basically the same, the difference is that a limit switch 55 is installed on the outer wall of the side of the T-type ram 51 close to the cylinder piston 11, Such as image 3 and Figure 4 As shown, the limit switch 55 is used to detect whether the cylinder piston 11 is accurately reset. The effect diagram after the cylinder knife punching mechanism of embodiment 2 is installed on the main shaft of BT50 T-shaped ram is shown in Figure 5 .

[0027] In the above embodiments, the outer ring surfaces of the two cylindrical roller bearings 4 and the upper surface of the supporting ring 3 can be subjected to surface quenching heat treatment, so as to increase the surface hardness and wear resistance, and improve the service life of the knife punching mechanism.

Abstract

The invention discloses a cylinder knife beating mechanism of a T-shaped ram main shaft. The mechanism comprises a cylinder, a lever, a bearing ring and two cylindrical roller bearings, wherein the cylinder is arranged at the outer side of a T-shaped ram; a cylinder body of the cylinder is connected to a first fixed bracket through a pin shaft; one end of the lever is connected with a piston of the cylinder through a pin shaft, and the other end of the lever is mounted on the inner wall of the other side of the T-shaped ram through a pin shaft; a longitudinal through hole is formed in the lever; two fixed shafts are arranged on the lever, and are respectively positioned at the two sides of the longitudinal through hole; the two cylindrical roller bearings are respectively fixed on the two fixed shafts; the bearing ring is arranged rightly below the two cylindrical roller bearings, and coats the outer side of a piston of a knife beating cylinder of a T-shaped main shaft; a transverse through hole is formed in the bearing ring; and a bearing rod is inserted in the transverse through hole. The knife beating mechanism is simple in structure and convenient for installation and maintenance, can finish a knife beating action by only needing less knife beating force, and can radically solve the oil leaking problem of a traditional knife beating cylinder.

Description

technical field [0001] The invention belongs to the technical field of numerical control machining centers, and relates to a tooling mechanism for a T-shaped ram main shaft, in particular to a cylinder tooling mechanism for a T-shaped ram main shaft. Background technique [0002] The rear end of the existing T-type ram main shaft is equipped with a cutter cylinder, and the cutter cutter process is completed by the hydraulic oil in the cutter cylinder. For manufacturers of CNC machining centers, the T-shaped ram spindle is an outsourced part, and the cost of the spindle with the cutter cylinder device is nearly 10,000 yuan higher than the spindle without the cutter cylinder structure. However, the T-shaped ram spindle with its own cutter cylinder is prone to hydraulic oil leakage. Once the hydraulic oil leaks, the leaked hydraulic oil will directly enter the spindle bearing, causing the bearing to burn out. Therefore, the existing T-shaped ram main shaft has certain deficien...
