Description

Technical Field

[0001] The utility model relates to a gear processing machine tool. Background Art

[0002] Gear machining machine tools are machine tools specially used for machining the gear parts of various cylindrical gears, bevel gears and other toothed parts. Gear machining machine tools are of various types and specifications, including small machine tools for machining gears with a diameter of several millimeters, large machine tools for machining gears with a diameter of more than ten meters, high-efficiency machine tools for mass production and high-precision machine tools for machining precision gears.

[0003] Existing gear processing machines generally require manual loading, where the corresponding gear to be cut is fixed on one side of a gear shaping device, and then the gear shaping device cuts teeth of the same pitch on the surface of the gear, and then the gear is taken out after completion. However, the above loading method is relatively cumbersome, and the gear cutting takes a long time, resulting in low work efficiency. Utility Model Content

[0004] The utility model aims to provide a gear processing machine tool which can automatically load materials, has a high gear cutting speed and high working efficiency.

[0005] The above technical objectives of the utility model are achieved through the following technical solutions:

[0006] A gear processing machine tool comprises: a frame; a workbench arranged in the middle of the frame, for placing the gear to be cut; a driving rod arranged above the workbench, and a gear cutter is arranged at the bottom of the driving rod; a cylinder connected to the top of the driving rod; wherein a gear piece is connected to one side of the driving rod, and a gear is meshed with one side of the gear piece, and the gear is connected to a rotating shaft connected to the frame bearing.

[0007] The utility model is further configured as follows: a gear rod is meshed at one side of the bottom of the gear, and a push plate is connected to one side of the gear rod.

[0008] The utility model is further configured to include a feeding rack suspended on the workbench, wherein the feeding rack is used for placing a plurality of gears to be cut which are arranged in a longitudinal direction.

[0009] The utility model is further configured that: the shape of the gear cutter matches the shape of the outer teeth of the gear.

[0010] The utility model is further configured as follows: the push plate is arranged below the feeding rack.

[0011] The utility model is further configured that: when the cylinder drives the driving rod to move downward, the gear tooth part drives the gear to rotate clockwise.

[0012] The utility model is further configured that: when the gear rotates clockwise, the gear rod moves left and right on the workbench.

[0013] The utility model is further configured that: when the push plate moves to the left and is not below the feeding rack, the gear to be cut in the feeding rack enters onto the workbench.

[0014] The utility model is further configured that: when the cylinder drives the driving rod to move upward, the push plate moves to the right side to push the gear to be cut into the lower part of the gear cutter.

[0015] In summary, the utility model has the following beneficial effects: the gear processing machine tool can automatically load materials and has a fast gear cutting speed and high working efficiency. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "page", "bottom", "inside", "outside", "clockwise", "counterclockwise", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0021] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features.

[0022] In the description of the present utility model, "multiple" means two or more than two, unless otherwise clearly specified and specifically defined. In the present utility model, unless otherwise clearly specified and defined, the terms "installed", "connected", "connected", "fixed" and the like should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal connection of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to the specific circumstances.

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] like Figure 1-Figure 3 As shown, a gear 7 processing machine tool includes a frame 1. A workbench 2 for placing a gear 12 to be cut is arranged in the middle of the frame 1. A driving rod 3 is arranged on the frame 1 above the workbench 2, and a gear cutter 4 matching the outer tooth shape of the gear 7 is arranged at the bottom of the driving rod 3. A cylinder 5 is connected to the top of the driving rod 3. When the cylinder 5 moves down to overlap with the gear 12 to be cut, the outer edge of the gear 12 to be cut can be cut into a tooth shape, thereby achieving a faster gear cutting speed.

[0025] Correspondingly, a gear member 6 is connected to one side of the driving rod 3. A gear 7 is meshed with one side of the gear member 6. The gear 7 is connected to a rotating shaft 8. The rotating shaft 8 is connected to the frame 1 by a bearing. When the driving rod 3 moves downward under the action of the cylinder 5, the gear 7 can be driven to rotate.

[0026] A gear rod 9 is meshed on one side of the bottom of the gear 7. A push plate 10 is connected to one side of the gear rod 9. When the gear 7 rotates, the gear rod 9 can be driven to move left and right on the workbench 2, thereby driving the push plate 10 connected to the gear rod 9 to slide left and right.

[0027] Correspondingly, a feeding rack 11 for placing a plurality of gears 12 to be cut arranged in a longitudinal direction is provided above the push plate 10. The feeding rack 11 is suspended on the workbench 2.

[0028] As mentioned above, when the cylinder 5 drives the driving rod 3 to move downward, it can drive the gear member 6 to move downward, driving the gear 7 to rotate clockwise. The gear 7 drives the gear rod 9 to Figure 1 The left side movement shown in the figure drives the push plate 10 to move to the left. The push plate 10 moves outwards until the push plate 10 is no longer under the feeding rack 11, and the gear 12 to be cut in the feeding rack 11 enters the workbench 2.

[0029] When the cylinder 5 drives the driving rod 3 to move upward, the push plate 10 moves to the right, pushing the gear 12 to be cut into the lower part of the gear cutter 4. Repeating the above steps, the outer edge of the gear 12 to be cut is cut into a tooth shape, and the purpose of automatically conveying the gear 12 to be cut is achieved.

[0030] It should be noted that an empty slot is provided at the position of the workbench 2 corresponding to the gear member 6 to prevent interference between the gear member 6 and the workbench 2 .

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed, but such modifications are protected by patent law as long as they are within the scope of the claims of the present invention.
