Description

Technical Field

[0001] This utility model relates to the field of CNC center tooling equipment technology, and in particular to a four-axis rotary table with a rear-mounted motor. Background Technology

[0002] A four-axis rotary table, also known as a CNC indexing table or fourth axis, is a core accessory of CNC machine tools. By adding a rotational degree of freedom, it links with the X, Y, and Z axes to achieve high-precision machining of complex geometric shapes. Essentially, it is a high-precision rotary worktable that, controlled by a CNC system, allows the workpiece to rotate around a certain axis during machining, thereby completing multi-angle and multi-faceted machining tasks.

[0003] Four-axis rotary tables have become an indispensable functional component in CNC machining centers. Currently, most four-axis rotary tables on the market adopt a side-mounted motor structure. This motor arrangement takes up a lot of space. When the machine tool worktable is small, or when multiple four-axis rotary tables need to be arranged on the same worktable, the side-mounted motor method is often limited. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a four-axis turntable with a rear-mounted motor.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A four-axis rotary table with a rear-mounted motor includes a housing. A drive gear is installed on the back of the housing via a motor drive, and the drive gear drives a driven gear through an intermediate gear.

[0007] The cam shaft end is equipped with a driven gear, the cam shaft is provided with rollers, the housing is equipped with a turret, and the rollers are fixedly installed on the turret.

[0008] The cylinder housing is fixedly mounted on the housing, and a brake ring is fitted on the piston rod of the cylinder housing. Brake pads are also fitted on the turret to match the brake rings.

[0009] In addition, a preferred structure is that a motor connecting plate is fixedly installed at the rear of the housing, the motor is fixedly mounted on the motor connecting plate, and the drive gear transmission is installed on the output shaft of the motor.

[0010] In addition, a preferred structure is that a transition gear mounting plate is fixedly provided on the motor connecting plate, and a transition gear is rotatably mounted on the transition gear mounting plate via a rotating shaft. The transition gear is located between the driving gear and the driven gear, and the transition gear meshes with the driving gear and the driven gear respectively for transmission.

[0011] Furthermore, in a preferred configuration, the driven gear is fixed to the end of the cam by a shrink sleeve.

[0012] Furthermore, in a preferred configuration, the camshaft has a groove in the middle, and rollers are engaged within the groove.

[0013] In addition, a preferred structure is that the housing is provided with a turntable bearing, and the turret is fixedly installed on the end face of the turntable bearing.

[0014] Furthermore, in a preferred configuration, the dial is located at the front end of the turntable bearing.

[0015] The beneficial effects of this utility model are as follows: the output of motor power can be realized through the meshing transmission between the driving gear, the intermediate gear and the driven gear, and the matching arrangement between the roller and the turret. Braking can be realized through the matching arrangement between the brake ring and the brake pad. In this solution, the motor is arranged at the rear end of the housing, which reduces the left and right width of the overall turntable. It can also be arranged on a small machine tool workbench, saving space. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Reference Figure 1-3A four-axis rotary table with a rear-mounted motor includes a housing 4. A drive gear 15 is mounted on the back of the housing 4 via a motor 16, and the drive gear 15 drives a driven gear 10 via a transition gear 12. The driven gear 10 is mounted on the shaft end of a cam 5, and rollers 6 are mounted on the shaft of the cam 5. A turret 3 is installed inside the housing 4, and the rollers 6 are fixedly mounted on the turret 3. A cylinder housing 9 is fixedly mounted on the housing 4, and a brake ring 8 is fitted onto the piston rod of the cylinder housing 9. Brake pads 7 are fitted onto the turret 3 corresponding to the brake ring 8.

[0022] A motor connecting plate 14 is fixedly installed at the rear of the housing 4. The motor 16 is fixedly mounted on the motor connecting plate 14, and the drive gear 15 is driven and installed on the output shaft of the motor 16. The motor connecting plate 14 enables the motor 16 to be fixedly installed on the back of the housing 4.

[0023] The motor connection plate is fixedly equipped with a transition gear mounting plate 13. A transition gear 12 is rotatably mounted on the transition gear mounting plate 13 via a rotating shaft. The transition gear 12 is located between the driving gear 15 and the driven gear 10, and meshes with both the driving gear 15 and the driven gear 10 for transmission. The transition gear mounting plate 13 allows for the installation of the transition gear 12, enabling the driving gear 15 to drive the transition gear 12 and rotate the driven gear 10.

[0024] The driven gear 10 is fixed to the shaft end of the cam 5 by a tension sleeve 11. The tension sleeve 11 allows the driven gear 10 to be stably mounted on the end of the cam 5.

[0025] The camshaft has a groove in the middle, and the rollers 6 are engaged in the groove. When the cam 5 rotates, the rollers also drive the turret 3 to rotate.

[0026] The housing 4 is equipped with a turntable bearing 2, and the turret 3 is fixedly installed on the end face of the turntable bearing 2.

[0027] The dial 1 is located at the front end of the turntable bearing 2. The dial 1 facilitates the arrangement and clamping of products by the customer.

[0028] In this embodiment, the motor 16 is arranged at the rear end of the housing 4 and connected by the motor connecting plate 14. The drive gear 15 is mounted on the shaft of the motor 16 and fixed as one piece, so that the motor 16 can transmit power to the drive gear 15.

[0029] The intermediate transition gear 12 is mounted on the shaft of the transition gear mounting plate 13 and can rotate freely around the shaft. It meshes with the driving gear 15 and the driven gear 10 meshes with the transition gear, thus realizing the transmission of the driven gear 10.

[0030] The driven gear is fixed to the end of the cam 5 shaft by the shrink sleeve 11. A roller 6 is engaged in the groove on the cam 5 shaft. The roller 6 is fixedly installed on the turret 3. When the cam 5 rotates, the roller 6 also drives the turret 3 to rotate.

[0031] The turret 3 is fixed to the end face of the turntable bearing 2, the turntable bearing 2 is fixed to the housing 4, the rear end of the turret 3 is fixed with a brake pad 7, and the cylinder housing 9 is fixed to the housing 4.

[0032] A brake ring 8 is provided on the piston rod on the cylinder housing 9. When braking, the oil / gas entering the chamber of the cylinder housing 9 pushes the brake ring 8, causing it to press against the brake pad 7 and against the left side of the housing end face of the brake pad 7, thereby achieving braking.

[0033] This structure differs from conventional four-axis rotary tables with the motor mounted on the side. Its motor 16 is located at the rear end of the housing 4, which greatly reduces the overall width of the rotary table. It can be arranged on smaller machine tool worktables. On normal-sized machine tool worktables, compared to conventional four-axis rotary tables, it can achieve multi-rotor arrangement or more optimized arrangement schemes.

[0034] In this invention, the output of motor power can be achieved through the meshing transmission between the driving gear 15, the transition gear 12 and the driven gear 10, and the matching arrangement between the roller 6 and the turret 3. Braking can be achieved through the matching arrangement between the brake ring 8 and the brake pad 7. In this solution, the motor 16 is arranged at the rear end of the housing 4, which reduces the left and right width of the overall turntable. It can also be arranged on a smaller machine tool workbench, saving space.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
