Description

Technical Field

[0001] The utility model relates to the technical field of numerically controlled lathes, in particular to a numerically controlled lathe used for gear processing. Background Art

[0002] Gears are mechanical components with teeth on the wheel rim that can continuously mesh to transmit motion and power. Gears are generally formed on CNC lathes through milling, gear shaping, gear hobbing and other methods. Since the debris on the tooth column during processing is relatively small and sharp, the direction of the flying debris cannot be well controlled during the processing, causing the debris to fly in all directions. If there is no protective mechanism around, it is easy to injure people. In addition, during the cleaning process, it is necessary to use a brush to clean in many aspects to prevent debris from remaining on the machine tool. If there is no protective mechanism, it will increase the difficulty of cleaning the debris and reduce the cleaning efficiency. Utility Model Content

DETAILED DESCRIPTION

[0018] The present invention will be further described in detail below with reference to the accompanying drawings and specific implementation methods.

[0019] A CNC lathe for gear machining, such as Figures 1 to 4 As shown, it includes a machine tool 1 and a controller, a tool feed box 2 is slidably provided on the left side of the machine tool 1, a workpiece feed box 3 is slidably provided on the right side of the machine tool 1, an ash hopper 4 whose top is flush with the surface of the machine tool 1 is installed in the central through hole 10 opened in the center of the machine tool 1, the bottom of the ash hopper 4 is connected to the collecting box 5, a protective component is slidably installed around the ash hopper 4 for protection, and lifting cylinders 6 connected to the protective component are symmetrically provided on the left and right sides of the collecting box 5, and the controlled ends of the tool feed box 2, the workpiece feed box 3 and the lifting cylinder 6 are connected to the output end of the controller.

[0020] The protection assembly includes a U-shaped base 9 connected to the lifting cylinder 6. Figure 3 As shown, a left baffle 11, a right baffle 12, a front baffle and a rear baffle are respectively provided at the inner edges around the base 9, and adjacent baffles are connected by connecting members.

[0021] The left baffle plate 11 is provided with a first side hole 18 for the tool mounting bracket 7 on the tool feeding box 2 to pass through, and a flexible protective ring 20 is provided around the first side hole 18 .

[0022] The right baffle plate 12 is provided with a second side hole 19 for the clamper 8 on the workpiece feeding box 3 to pass through, and a flexible protective ring 20 is provided around the second side hole 19 .

[0023] The front baffle includes a front fixed baffle 14 fixedly arranged on the front side of the inner circle of the base 9. The front fixed baffle 14 is hinged to the top front movable baffle 13 through a hinge joint 17. When installing the workpiece and the tool, the front movable baffle 13 can be flipped and laid flat for easy operation.

[0024] The rear baffle plate includes a rear fixed baffle plate 16 fixedly arranged on the rear side of the inner circle of the base 9 , and the rear fixed baffle plate 16 is hinged to the rear movable baffle plate 15 at the top through a hinge joint 17 .

[0025] The connecting member includes a connecting plate 22 and positioning pins 21 respectively arranged on both sides of the baffle. Figure 4 As shown, the two positioning pins 21 between the connecting plate 22 and the adjacent baffles are assembled to connect the adjacent baffles.

[0026] The tool feed box 2 is provided with a travel motor for driving the tool feed box 2 and a rotary motor for driving the tool mounting frame 7 .

[0027] A driving motor for driving the workpiece feeding box 3 and a motor for driving the clamper 8 are arranged in the workpiece feeding box 3 .

[0028] When gear forming processing is required, the protective assembly is first lifted to the top of the machine tool 1 by the lifting cylinder 6 to align it with the center of the tool mounting frame 7 and the clamp 8.
