Description

Technical Field

[0001] The utility model belongs to the technical field of gear processing, and particularly relates to a processing machine tool applicable to gears of different sizes. Background Technique

[0002] A gear refers to a mechanical element with teeth on the rim that continuously meshes to transmit motion and power. Gears can be divided into parts such as teeth, tooth spaces, end faces, normal faces, addendum circles, dedendum circles, base circles, and pitch circles according to their structures. The application of gears in transmission has emerged very early. Gear processing machine tools are required in the process of gear processing. Gear processing machine tools are used to process the tooth parts of various cylindrical gears, bevel gears, and other toothed parts. Gear processing machine tools are widely used in various machinery manufacturing industries such as automobiles, construction machinery, mining machinery, metallurgical machinery, petroleum, instruments, airplanes, and spacecraft.

[0003] In the prior art, there is a gear processing machine tool with the patent publication number of CN220480450U. The above patent includes a processing machine tool body and a rotating mechanism. The rotating mechanism includes a rotating rod, a motor, a clamping block, a gear, and a processing component. The processing component provides processing conditions for the processing machine tool body to process gears. The motor provides rotation conditions for the rotating rod to drive the gear to rotate. The clamping block provides a clamping function for the gear. When the gear is processed, the inner side wall of the gear first sleeves on the outer side wall of the rotating rod, and then the two ends of the gear are fastened along the outer side wall of the rotating rod through the clamping block, so that the clamping block firmly fixes the gear. Then, the motor is driven to rotate the rotating rod, and the rotating rod drives the gear to rotate, enabling the gear to rotate, solving the problem of gear rotation. However, there are still the following deficiencies in actual use: Most gear processing machine tools are only applicable to gears of the same size. When processing gears of different sizes, different processing machine tools or different fixtures need to be replaced, resulting in low processing efficiency, and it is not easy to collect and process the waste materials generated during gear processing in a timely manner. The accumulation of waste materials on the machine tool easily affects the processing effect.

[0004] Therefore, a processing machine tool applicable to gears of different sizes is needed to solve the problems in the prior art that it is not easy to fix gears of different sizes with the processing machine tool and it is not easy to collect the waste materials generated during processing.

[0009] Further, it is worth noting that a driven gear is tightly sleeved on the outer surface of the threaded rod close to the turntable, a first motor is embedded and installed on the outer wall of the turntable close to the threaded rod, and a driving gear meshed with the driven gear is coaxially fixedly connected to the output end of the first motor.

A fixing seat 2 is fixedly connected to the top surface of the body 1. A same rotating shaft 3 is rotatably connected between the centers of the outer walls on both sides of the fixing seat 2. A turntable 4 is coaxially and fixedly connected to the outer wall on one side of the rotating shaft 3. A fixing mechanism 5 is arranged on the side of the turntable 4 away from the rotating shaft 3. A cleaning component 6 is arranged inside the body 1;

[0023] The fixing mechanism 5 includes a threaded rod 51. One outer wall of the threaded rod 51 is rotatably connected to the center of the outer wall of the turntable 4. A threaded sleeve 52 is threadedly connected to the outer surface of the threaded rod 51. A rotating ring 53 is rotatably connected to the outer surface of the threaded sleeve 52. Four first connecting rods 54 distributed in a circular pattern are hinged to the outer surface of the rotating ring 53 through lugs and pin shafts. One end of each of the four first connecting rods 54 away from the rotating ring 53 is hinged to a top plate 55 through a pin shaft. Two fixing rings 56 distributed in parallel are tightly sleeved on the outer surface of the threaded rod 51. Second connecting rods 57 are hinged to the outer surfaces of the two fixing rings 56 and the bottom surfaces of the four top plates 55 through lugs and pin shafts.

[0024] Further, as shown in Figure 1 and Figure 4 It is worth specifically stating that the cleaning component 6 includes a collection tank 61 and a discharge port 62. The collection tank 61 is opened on the top surface of the machine body 1. The discharge port 62 is opened on one outer wall of the machine body 1 and is communicated with the collection tank 61. A conveyor belt 63 is arranged between the inner end walls of the collection tank 61 and the discharge port 62.

[0025] Further, as shown in Figure 2 and Figure 3 It is worth specifically stating that a driven gear 7 is tightly sleeved on the outer surface of the threaded rod 51 close to the turntable 4. A first motor 8 is embedded and installed on the outer wall of the turntable 4 close to the threaded rod 51. The output end of the first motor 8 is coaxially and fixedly connected to a driving gear 9 that meshes with the driven gear 7.

[0026] Further, as shown in Figure 1 and Figure 2 It is worth specifically stating that a driven bevel gear 10 is coaxially and fixedly connected to the outer wall of the rotating shaft 3 away from the turntable 4. A protective shell 11 is fixedly connected to one outer wall of the fixed seat 2 corresponding to the driven bevel gear 10. A second motor 12 is fixedly connected to the top surface of the machine body 1. The output end of the second motor 12 extends into the protective shell 11 and is coaxially and fixedly connected to a driving bevel gear 13 that meshes with the driven bevel gear 10.

[0027] Further, as shown in Figure 3 It is worth specifically stating that both the first connecting rod 54 and the second connecting rod 57 are inclined. The first connecting rod 54 and the adjacent second connecting rod 57 are symmetrically arranged, which is convenient for the threaded sleeve 52 to push the top plate 55 upward when moving.

[0028] Further, as shown in Figure 1 and Figure 3 It is worth specifically stating that the top surface of the top plate 55 is arc-shaped, which is convenient for fitting the inner wall of the shaft hole of the gear to be processed, improving the fixing effect.

[0029] In summary: When the processing machine tool is in use, first, the gear to be processed is sleeved on the outer surfaces of the four top plates 55. The first motor 8 is started to drive the driving gear 9 to rotate. Under the meshing action, the driven gear 7 is driven to rotate. The driven gear 7 drives the threaded rod 51 to rotate. Under the action of the thread, the threaded sleeve 52 moves towards the fixed ring 56. When the threaded sleeve 52 moves, it pushes the first connecting rod 54 to rotate. At the same time, with the cooperation of the second connecting rod 57, the top plates 55 move upward. When the top surfaces of the four top plates 55 synchronously move to contact the inner wall of the gear shaft hole to be processed, the fixation of the gear to be processed is realized. The operation is simple, suitable for gear workpieces of different sizes, and effectively avoids the problem that the processing machine tool is not easy to fix gears of different sizes.

[0030] When processing the gear workpiece, the second motor 12 is started to drive the driving bevel gear 13 to rotate. Under the meshing action, the driven bevel gear 10 is driven to rotate. The driven bevel gear 10 drives the turntable 4 and the fixing mechanism 5 as a whole to rotate through the rotating shaft 3, which is convenient for processing the gear workpiece. The waste generated during the processing falls into the collection tank 61 and lands on the top surface of the conveyor belt 63. The conveyor belt 63 is started to discharge the waste through the discharge port 62, effectively avoiding the problem that the processing machine tool is not easy to collect the waste generated during processing.

[0031] The first motor 8 and the second motor 12 can be purchased on the market. The first motor 8 and the second motor 12 are equipped with power supplies, which are mature technologies in this field and have been fully disclosed. Therefore, they are not repeated in the specification.
