Description

Technical Field

[0001] The utility model relates to the field of fixtures, and particularly relates to a fixture for a planetary carrier tooling. Background Art

[0002] A planetary gear set is a complex gear system, which is widely used in multiple fields, especially in the automotive industry, machine tools and industrial machinery, aerospace, ships and marine engineering, as well as household appliances and consumer goods. The planetary gear set mainly consists of a sun gear, multiple planetary gears, an outer gear ring (or inner gear ring), and a planetary carrier, four core components. Its working principle can achieve different transmission ratios and transmission directions through different power input and output methods. For example, power can be input from the sun gear, transmitted through the planetary gears to the outer gear ring or the planetary carrier for output; or power can be input from the planetary carrier, transmitted through the planetary gears to the sun gear or the outer gear ring for output, etc.

[0003] During the assembly process of the planetary gear set, a fixture is required to fix the planetary carrier to facilitate the installation of the planetary gear set. After the installation of the planetary gear set is completed, a fixture is also required to fix the outer gear ring to facilitate the detection of whether the assembled planetary gears can rotate normally in the outer gear ring. The existing fixtures can only fix the planetary carrier and the outer gear ring separately, and the fixtures need to be repeatedly replaced during the assembly process, which is inconvenient to use. Therefore, a fixture for a planetary carrier tooling is proposed. Content of the Utility Model

Specific embodiments

[0021] In order to make the technical means, creative features, achieved purposes and effects of the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0022] As Figure 1 Figure 2 shown, a planet carrier tooling fixture includes an equipment base 1.

The fixture assembly 5 can respectively fix the planet carrier 3 and the external gear ring, facilitating the user to install the entire planetary gear set 2. At the same time, the detection mechanism 6 can facilitate the user to detect whether the assembled planet gears can run stably within the external gear ring.

[0023] As Figure 3As shown, the fixture assembly 5 includes a fixture frame body 501 fixedly installed at the edge of the equipment base 1. A first oil cylinder 503 and a second oil cylinder 504 are fixedly installed on the fixture frame body 501. Buffer rubber pads 502 are fixedly installed at the output ends of the first oil cylinder 503 and the second oil cylinder 504. The fixture assembly 5 further includes a first installation groove 506 and a second installation groove 507 opened on the fixture frame body 501. Oil cylinder pipes 505 are connected to both the first oil cylinder 503 and the second oil cylinder 504.

[0024] Specifically, during use, the planet carrier 3 can be placed on the equipment base 1. After the planet carrier 3 is placed on the equipment base 1, the first oil cylinder 503 can be controlled to extend. After the first oil cylinder 503 extends, its end will press against the side wall of the planet carrier 3, thereby fixing planet carriers 3 of different sizes. After the planet carrier 3 is fixed, it is convenient for the user to install the entire planetary gear set 2. After the planetary gear set 2 is installed, the first oil cylinder 503 can be retracted and the second oil cylinder 504 can be controlled to extend. After the second oil cylinder 504 extends, its end will press against the outer gear ring of the planetary gear set 2, thereby fixing the outer gear ring.

[0025] As Figure 4 shown, the detection mechanism 6 includes a sliding frame body 603 movably installed inside the equipment base 1. A drive motor 602 is fixedly installed on the sliding frame body 603. A first helical gear 605 is fixedly installed at the output end of the drive motor 602. A drive shaft 604 is movably installed on the sliding frame body 603. A drive disk 607 is fixedly installed at the upper end of the drive shaft 604. A second helical gear 606 is fixedly installed at the middle position of the drive shaft 604. The detection mechanism 6 further includes a movable slide plate 601 movably installed inside the movable chute 4, and the lower end of the movable slide plate 601 is fixed to the sliding frame body 603.

[0026] Specifically, after the outer gear ring is fixed, the drive motor 602 can be started. After the drive motor 602 is started, it will drive the first helical gear 605 to rotate. After the first helical gear 605 rotates, it will drive the drive shaft 604 on the second helical gear 606 to rotate. After the drive shaft 604 rotates, it will drive the drive disk 607 to rotate. Then, the movable slide plate 601 can be manually pushed forward to make the rotating drive disk 607 abut against the planet carrier 3, driving the planet carrier 3 to rotate, and detecting whether the assembled planet gears can run stably within the outer gear ring.

[0027] It should be noted that the present utility model is a fixture for a planet carrier. During actual use, first place the planet carrier 3 on the equipment base 1. Since the first oil cylinder 503 is installed on the fixture frame 501 through the first installation groove 506, and the second oil cylinder 504 is installed on the fixture frame 501 through the second installation groove 507, and both the first oil cylinder 503 and the second oil cylinder 504 are installed on the edge of the equipment base 1 through the fixture frame 501. After the planet carrier 3 is placed on the equipment base 1, the first oil cylinder 503 or the second oil cylinder 504 can be controlled to extend. After the first oil cylinder 503 extends, its end will press against the side wall of the planet carrier 3, thereby fixing the planet carrier 3, which is convenient for the user to install the entire planetary gear set 2. After the second oil cylinder 504 extends, its end will press against the outer gear ring of the planetary gear set 2, thereby fixing the outer gear ring. After the outer gear ring is fixed, the drive motor 602 can be started. Since the second helical gear 606 is movably installed on one side of the first helical gear 605 through the drive shaft 604, and the first helical gear 605 meshes with the second helical gear 606, after the drive motor 602 is started, it will drive the drive disk 607 to rotate. After the drive disk 607 rotates, the movable slide plate 601 can be manually pushed forward. When the movable slide plate 601 moves forward, it will drive the sliding frame 603 forward. After the sliding frame 603 moves forward, the drive disk 607 will contact the planet carrier 3, and the rotating drive disk 607 will drive the planet carrier 3 to rotate to detect whether the assembled planet gears can run stably within the outer gear ring.
