Description

Technical Field

[0001] The utility model relates to the technical field of gear heads for machining centers, in particular to a horizontal gear head for machining centers. Background Art

[0002] Traditional horizontal gearheads used in machining centers typically rely on manual shifting to adjust speed and torque output, which is not only time-consuming and labor-intensive but also prone to human error. With the advancement of industrial automation, the demand for improving production efficiency and reducing labor costs is growing. Therefore, the development of a horizontal gearhead with automatic shifting and self-locking functions has become an inevitable trend in the industry. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the present invention is to provide a horizontal gear head for a machining center, which is used to solve the problem of time-consuming and labor-intensive manual gear shifting in the prior art.

[0004] To achieve the above-mentioned and other related purposes, the present invention provides the following technical solutions:

[0005] A horizontal gear head for a machining center includes a gear box, a spindle arranged at one end of the gear box, and a motor arranged at the other end of the gear box. A pad is provided between the motor and the gear box, and a knife-beating cylinder is provided on the pad. The gear box is also provided with a shift cylinder on one side of the motor; slides for installation on the machining center are symmetrically provided on both sides of the gear box.

[0006] To implement the above technical solution, the horizontal gear head consists of a gear box, a spindle and a motor. One end of the gear box is connected to the spindle for installing the tool, and the other end is connected to the motor for providing power. A pad is set between the motor and the gear box, and a tool cylinder is installed on the pad to realize the automatic tool changing function. A shift cylinder is provided on one side of the gear box to control the switching of gears and achieve different speeds and torque outputs. Slides are symmetrically provided on both sides of the gear box. These slides are used to install the gear head on the machining center to ensure its accurate and stable positioning.

[0007] In one embodiment of the present invention, the shift cylinder includes an upper oil circuit seat, a base plate, a base embedded in the base plate, and a sleeve arranged between the upper oil circuit seat and the base; a shift rod is provided in the sleeve, a shift piston is provided on the shift rod, and the inner cavity of the sleeve is divided into a rod cavity and a rodless cavity by the shift piston; a high-speed oil port connected to the rodless cavity is provided on the upper oil circuit seat, and a low-speed oil port connected to the rod cavity is provided on the base.

[0008] To implement this technical solution, the base is embedded in the baseplate, forming a closed cylinder space with the upper oil manifold. The upper oil manifold has a high-range oil port for connecting to the rodless chamber, while the base has a low-range oil port for connecting to the rod chamber. By controlling the opening and closing of these ports, the flow of hydraulic oil can be changed, thereby achieving gear shifting. When the hydraulic system supplies oil to the rodless chamber, the shift piston pushes the shift rod to shift to a high gear; conversely, supplying oil to the rod chamber enables a low gear shift.

[0009] In one embodiment of the present invention, a push head is provided in the rodless cavity, and a push head piston corresponding to the shift piston is sleeved on the push head; a top groove is provided on the side of the shift rod close to the push head, and a push rod is provided on the push head which is threadedly connected to the top groove.

[0010] To implement this technical solution, a push rod is installed on the side of the ram near the shift lever, and a top groove is provided on the shift lever for the push rod to fit in. When the rodless chamber is filled with hydraulic oil, the generated thrust acts on the ram piston, which is then transmitted to the shift lever through the push rod. The push rod fits into the top groove of the shift lever, ensuring that the shift lever can stably move to the predetermined position under the action of hydraulic oil pressure and lock the gear in a specific gear. The design of the ram piston ensures the accuracy of the shift action and reduces errors caused by hydraulic oil pressure fluctuations.

[0011] In one embodiment of the present invention, an annular locking groove is provided on the plug, and a self-locking device for locking the plug through the locking groove is provided on the upper oil passage seat.

[0012] To achieve this technical solution, the mandrel is specially designed with an annular locking groove and a self-locking device integrated into the upper oil channel seat. This device interacts with the mandrel through the annular locking groove to achieve a self-locking function. The use of the self-locking device improves shifting reliability, ensuring that the gear head maintains the shift position even under long-term operation or in vibrating environments.

[0013] In one embodiment of the utility model, the self-locking device includes a fixed plate, a connecting plate connecting the upper oil circuit seat and the fixed plate, the inner cavity of the fixed plate and the connecting plate form a self-locking cavity that passes through the rodless cavity; a locking head that can abut against the locking groove is provided in the self-locking cavity, and a spring is provided between the locking head and the fixed plate.

[0014] To implement the above technical solution, a lock head is installed in the self-locking cavity, which abuts against the annular lock groove on the top head. A spring is installed between the lock head and the fixed plate, ensuring that the lock head is stably retained in the lock groove under the action of the spring force, thus achieving self-locking. To unlock, pressurized oil is introduced into the rodless cavity, and the pressure causes the lock head to withdraw from the lock groove, allowing the shift lever to move to another position and achieve gear shifting.

[0015] In one embodiment of the present invention, a fuel filling port is provided on the gear box.

[0016] To implement the above technical solution, a refueling port is specially designed on the gearbox, which is located at a convenient position to facilitate users to add lubricating oil to the gearbox. At the same time, when there is too much lubricating oil in the gearbox, the refueling port can serve as an oil drain port.

[0017] In one embodiment of the present invention, the gear box is provided with an oil mirror and a plurality of universal curved tubes on one side of the main shaft.

[0018] To implement the above technical solution, the gearbox is equipped with an oil mirror on one side of the spindle. This is a transparent window that allows the operator to directly observe the lubricating oil condition inside the gearbox; the universal curved pipe is integrated with the distributor to ensure that the coolant, cutting fluid or gas can be efficiently distributed to the key parts of the workpiece, thereby improving the processing quality.

[0019] As described above, the horizontal gear head for the machining center of the utility model has the following beneficial effects: by setting the tool-beating cylinder and the shifting oil cylinder, the automatic tool changing and gear shifting functions are realized, which greatly reduces manual intervention, improves the degree of automation of the equipment, and thus significantly improves production efficiency; the automatic gear shifting function reduces the workload of the operator and reduces the risk of errors due to human factors; the slides symmetrically arranged on both sides provide better support and positioning, ensure the stable installation of the equipment on the machining center, and improve the smoothness and reliability of the equipment operation; the design of the self-locking device improves the reliability of gear switching and reduces the problem of unstable gear shifting caused by vibration or long-term work.
