Description

A rotating jig Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a rotary fixture. Background Technology

[0002] Rotary fixtures are used to control the rotation of workpieces. Mobile phone chips need to be mounted and processed using this type of rotary fixture. In order to improve efficiency, a multi-axis output structure is usually adopted. In the past, a transition gear was used to drive between two adjacent axes. This structure is not stable enough, and the gap between the gears cannot be adjusted, resulting in poor transmission accuracy. If a synchronous belt control is used, two adjacent gears need to be connected by a synchronous belt, which is complex and costly. Therefore, further improvements are needed. Summary of the Invention

[0003] The purpose of this invention is to provide a rotary fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A rotary fixture includes a housing, an input shaft, and several output shafts. The input shaft extends into the housing from the bottom. The several output shafts are arranged horizontally and vertically rotatably connected to the housing via two first bearings. It also includes several sets of transmission components and adjustment components. A drive gear is mounted on the input shaft. A driven gear is mounted in the middle of each output shaft. The transmission components are installed inside the housing and spaced apart between the input and output shafts. Two sets of transmission components are diagonally distributed on both sides of the output shaft. Each transmission component includes a rotating shaft, a transmission gear, and two second bearings. The upper and lower ends of the rotating shaft are rotatably connected to the housing via the second bearings. The transmission gear is mounted in the middle of the rotating shaft. The number of adjustment components is the same as the number of transmission components. The adjustment components are installed on the front and rear sides of the housing and apply pressure towards the inside of the housing, contacting the transmission components.

[0006] Further description of this utility model: the adjustment assembly includes a grommet screw and a compression spring; two screw holes are provided on the front and rear sides of the housing near the transmission assembly, one above the other; the grommet screw is installed in the screw hole; the compression spring is located in the screw hole and its two ends abut against the end of the grommet screw and the second bearing, respectively.

[0007] As further described in this utility model, a corrugated gasket is installed at the bottom of the first bearing below each of the output shafts.

[0008] In a further description of this utility model, a set of transition gear assemblies is provided between the input shaft and its adjacent input shaft; the structure of the transition gear assembly is the same as that of the transmission assembly and is connected between the two sets of transmission assemblies.

[0009] In a further description of this utility model, the input shaft is located in the middle of the housing; the output shaft is distributed on the left and right sides of the input shaft.

[0010] In a further description of this utility model, the housing includes an upper shell and a lower shell; the upper shell and the lower shell are positioned by a locating pin and fixed by screws.

[0011] The beneficial effects of this utility model are as follows:

[0012] This design uses transmission components diagonally distributed on both sides of the input and output shafts for transmission. The transmission components are then pressed towards the inside of the housing by the adjustment component, which can effectively eliminate gaps, achieve close cooperation between the gears, and improve transmission accuracy.

[0017] The present invention will be further described below with reference to the accompanying drawings:

[0018] As shown in Figures 1-4, a rotary fixture includes a housing 1, an input shaft 2, and several output shafts 3. The input shaft 2 extends into the housing 1 from the bottom. The several output shafts 3 are arranged horizontally and vertically rotatably connected to the housing 1 via two first bearings 31. The fixture also includes several sets of transmission components 4 and adjustment components 5. A drive gear 21 is mounted on the input shaft 2. A driven gear 32 is mounted in the middle of the output shaft 3. The transmission components 4 are installed inside the housing 1 and spaced apart between the input shaft 2 and the output shafts 3. Two sets of transmission components 4 located on both sides of the output shaft 3 are diagonally distributed on both sides of the output shaft 3, while only one set of transmission components 4 is needed on the side of the output shaft 3 furthest from the input shaft 2. The transmission components 4 include a rotating shaft 41 and transmission gears. The shaft 41 has a wheel 42 and two second bearings 43; the upper and lower ends of the shaft 41 are rotatably connected to the housing 1 through the second bearings 43; the transmission gear 42 is installed in the middle of the shaft 41; the number of adjustment components 5 is the same as the number of transmission components 4; the adjustment components 5 are installed on the front and rear sides of the housing 1, and apply pressure to the transmission components 4 in the direction of the housing 1; the input shaft 2 of this design is connected to the drive device to input power, and the power is transmitted to the output shaft 3 through the transmission components 4, which drives each output shaft 3 to rotate synchronously. The transmission components 4 are diagonally distributed on both sides of the output shaft 3 for transmission, and the adjustment components 5 press the transmission components 4 in the direction of the housing 1, thereby effectively eliminating gaps, realizing close cooperation of each gear, and improving transmission accuracy.

[0019] The adjustment assembly 5 includes a grommet screw 51 and a compression spring 52; the front and rear sides of the housing 1 are provided with two screw holes distributed vertically on the side near the transmission assembly 4; the grommet screw 51 is installed in the screw hole; the compression spring 52 is located in the screw hole and its two ends abut against the end of the grommet screw 51 and the second bearing 43 respectively. By adjusting the installation depth of the grommet screw 51, the clamping force of the compression spring 52 on the second bearing 43 is adjusted, so that the transmission gear 42 closely cooperates with its two adjacent gears.

[0020] Each of the first bearings 31 below the output shaft 3 is equipped with a corrugated gasket 33 to prevent hard contact and provide a certain degree of protection.

[0021] A set of transition gear assembly 6 is provided between the input shaft 2 and its adjacent input shaft 2; the structure of the transition gear assembly 6 is the same as that of the transmission assembly 4 and is connected between the two sets of transmission assemblies 4. This arrangement can increase the distance between the input shaft 2 and the output shaft 3 to adapt to the requirements of the operating environment.

[0022] The input shaft 2 is located in the middle of the housing 1; the output shaft 3 is distributed on the left and right sides of the input shaft 2, transmitting power from the middle to both sides.

[0023] The housing 1 includes an upper shell 11 and a lower shell 12; the upper shell 11 and the lower shell 12 are positioned by locating pins and fixed by screws.

[0024] The above description does not limit the technical scope of this invention. Any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of this invention shall still fall within the scope of the technical solution of this invention.
