Description

Technical Field

[0001] The utility model relates to the technical field of drilling rigs, in particular to a gear hobbing machine base for machining transmission gears of drilling rigs. Background Art

[0002] The transmission gear transmits the power of the motor or engine to other parts of the drilling rig, such as the drill bit and drill rod, so that they can rotate and perform drilling operations. The shaft hole diameters of the transmission gears in different functional parts are also different.

[0003] The base of the existing gear hobbing machine used for drilling rig transmission gear processing is a mechanism that rotatably supports the raw material disk of the gear. The conventional operation is to set the axial hole of the disk on the central shaft rod and rotate and tighten it based on the threaded disk. However, due to different requirements of different parts, the diameter of the axial hole of the disk also has certain differences, resulting in the axial hole of some disks and the axis of the central shaft rod being offset, affecting the accuracy of gear processing.

[0004] Existing drilling rig gear processing suffers from the following drawbacks: The diameter of the central shaft column in the base supporting the material tray cannot be adjusted, resulting in a limited size of the material tray that can be accommodated and fixed. This prevents the material tray from being properly and coaxially fixed, limiting the processing range of the gear hobbing machine. Therefore, we propose a gear hobbing base for drilling rig transmission gear processing. Summary of the Invention

[0005] The main purpose of the utility model is to provide a gear hobbing machine base for drilling rig transmission gear processing, which can effectively solve the problems in the background technology.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0007] A gear hobbing machine base for processing transmission gears of a drilling rig includes a machine base, a turntable and a claw-type expansion sleeve, a threaded column and a tapered pressure cylinder. A bearing is provided on the top of the machine base, a turntable is provided on the top of the bearing, a claw-type expansion sleeve is welded and connected at the center of the top of the turntable, a threaded column is inserted in the claw-type expansion sleeve, the bottom of the threaded column is welded and connected to the turntable, and a tapered pressure cylinder is sleeved on the threaded column.

[0008] Furthermore, an internal threaded hole corresponding to the threaded column is opened at the center of the conical pressing cylinder, and the conical pressing cylinder is threadedly connected to the threaded column through the internal threaded hole. A handle is welded and connected to the periphery of the conical pressing cylinder at equal distances.

[0009] Furthermore, a servo motor is installed on the bottom of the machine base through bolts, and the driving end of the servo motor is installed and connected to the center of the bottom circle of the turntable.

[0010] Furthermore, the bottom of the outer sleeve of the bearing is installed and connected to the machine base through bolts, and the top of the inner sleeve of the bearing is installed and connected to the turntable through bolts.

[0011] Compared with the prior art, the present invention has the following beneficial effects: through the assembly consisting of a machine base, a turntable, a claw-type expansion sleeve, a threaded column and a tapered pressure cylinder, a machine base is provided for a gear hobbing machine used for drilling rig transmission gear processing, and a set of outward-expanding gear fixing mechanisms are set up, which can meet the installation of disc materials of various diameters. The expansion structure is used to expand and tighten the shaft hole of the disc material to be processed into a gear, so that the disc material can rotate with the turntable for rolling milling by the milling head of the gear hobbing machine, which solves the problem that the diameter of the shaft column in the machine base of the existing gear hobbing machine that cannot be adjusted and changed, resulting in a limited size of the disc that can be adapted and fixed, making it impossible for the disc to be coaxially tightened and installed, affecting the processing range of the gear hobbing machine.

[0018] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0019] like Figure 1-5 As shown, a gear hobbing machine base for drilling rig transmission gear processing includes a machine base 1, a turntable 2 and a claw-type expansion sleeve 3, and also includes a threaded column 4 and a conical pressure cylinder 5. A bearing 6 is provided on the top of the machine base 1, and a turntable 2 is provided on the top of the bearing 6.

When working, the material tray that needs gear hobbing is placed on the turntable 2, and the axial hole of the material tray is sleeved on the outer periphery of the claw-type expansion sleeve 3, and then the conical pressing cylinder 5 is sleeved on the threaded column 4. By rotating the conical pressing cylinder 5, the cone bottom of the conical pressing cylinder 5 gradually drops into the claw-type expansion sleeve 3, and as the conical pressing cylinder 5 continues to drop, the conical pressing cylinder 5 will expand the claw-type expansion sleeve 3, so that the claw-type expansion sleeve 3 can expand and press the axial diameter of the material tray while maintaining the inconvenience with the axis of the material tray, so that the material tray can be stably pressed on the turntable 2, and the turntable 2 is driven by the servo motor 7 to rotate the material tray, so that the material tray is firmly supported in rotation, so that the gear hobbing machine can perform gear hobbing processing on the rotated and fixed material tray.
