Description

Technical Field

[0001] This utility model relates to the field of rotary drive technology, specifically to a device for a gear-driven rack rotation mechanism. Background Technology

[0002] Rotary mechanisms are commonly used in product manufacturing to drive the product to different processing stations. For example, they are used to process a mechanism consisting of multiple parts sequentially at different stations.

[0003] For the above processing, a rotary mechanism using a divider turntable is typically employed. However, this type of rotary mechanism requires a large installation space and is difficult to control in terms of rotational precision, resulting in significant deviations in the rotational angle. Summary of the Invention

[0004] The purpose of this invention is to provide a device for a gear-driven rack rotation mechanism to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for a gear-driven rack rotation mechanism, comprising:

[0006] The outer casing, drive gear, rotating shaft, load-bearing platform, and rack;

[0007] The rotating shaft is rotatably installed inside the outer casing, and the upper end of the rotating shaft penetrates the outer casing and extends to the upper part of the outer casing. The bearing platform is installed at the upper end of the rotating shaft, and the drive gear is sleeved on the outer wall of the rotating shaft.

[0008] A through groove is provided on the side wall of the outer casing, and the rack is movably disposed in the through groove and meshes with the drive gear. It also includes a drive mechanism, which is used to drive the rack to move and drive the drive gear to rotate.

[0009] Preferably, a bearing is embedded in the lower side of the inner cavity of the outer shell, and the rotating shaft is rotatably connected to the outer shell through the bearing.

[0010] Preferably, both ends of the outer wall of the rack are slidably connected to a bearing seat.

[0011] Preferably, the drive mechanism includes two side plates, which are fixedly connected by a connecting plate, and a rodless cylinder is disposed between the two side plates, with the rack connected to the rodless cylinder.

[0012] Preferably, a second connecting plate is connected to the moving end of the rodless cylinder, and the second connecting plate is connected to the rack.

[0013] Preferably, a distance sensor is installed on the outer wall of the side plate, and the distance sensor corresponds to the position of the moving end of the rodless cylinder.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The rack and pinion mechanism, which works in conjunction with the drive gear, drives the platform to rotate. This design results in a relatively small overall space requirement. Furthermore, the movement of the rack allows the platform to rotate within a certain angular range. The rotation angle of the platform can be controlled by adjusting the movement of the rack, resulting in high accuracy. Attached Figure Description

Therefore, they should not be construed as limitations on this utility model.

[0022] Example 1:

[0023] Please see Figure 1-3 This utility model provides a technical solution: a device for a gear-driven rack rotation mechanism, comprising: a housing 1, a drive gear 4, a rotating shaft 3, a bearing platform 5, and a rack 7;

[0024] The rotating shaft 3 is rotatably installed inside the outer shell 1, and the upper end of the rotating shaft 3 passes through the outer shell 1 and extends to the upper part of the outer shell 1. The bearing platform 5 is installed on the upper end of the rotating shaft 3. The drive gear 4 is sleeved on the outer wall of the rotating shaft 3. A through groove is opened on the side wall of the outer shell 1. The rack 7 is movably disposed in the through groove and meshes with the drive gear 4. The system also includes a drive mechanism, which is used to drive the rack 7 to move and drive the drive gear 4 to rotate.

[0025] Analysis of the above content: When using it, follow as follows Figure 3 The diagram shows the device mounted on other supports or components. This solution is suitable for reciprocating rotary drives, but not for continuously rotating drives, such as... Figure 1 As shown, the two parts being processed on the carrier platform 5 can switch between processing. When one part is processed, the carrier platform 5 is rotated 180 degrees so that the other part can be processed. The movement of the rack 7 drives the drive gear 4, the rotating shaft 3, and the carrier platform 5 to rotate.

[0026] Example 2:

[0027] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: a bearing 2 is embedded in the lower side of the inner cavity of the outer shell 1, and the rotating shaft 3 is rotatably connected to the outer shell 1 through the bearing 2.

[0028] Based on the above analysis, the setting of bearing 2 ensures that the rotating shaft 3 operates smoothly.

[0029] Example 3:

[0030] Please see Figure 1-3 Based on Embodiment 1, this utility model provides a technical solution: both ends of the outer wall of the rack 7 are slidably connected to a bearing seat 6.

[0031] Analysis of the above content: By setting the bearing seat 6, the rack 7 is supported and bears the load, so that the rack 7 moves smoothly.

[0032] Example 4:

[0033] Please see Figure 1-3 This utility model provides a technical solution based on Embodiment 1: The driving mechanism includes two side plates 10, which are fixedly connected by a connecting plate 11. A rodless cylinder 9 is disposed between the two side plates 10, and a rack 7 is connected to the rodless cylinder 9. A connecting plate 8 is connected to the moving end of the rodless cylinder 9, and the connecting plate 8 is connected to the rack 7. A distance sensor 12 is installed on the outer wall of the side plate 10, and the distance sensor 12 corresponds to the position of the moving end of the rodless cylinder 9.

[0034] Analysis of the above content: The rodless cylinder 9 here adopts existing technology. The moving end of the rodless cylinder 9 (that is, it can move under pneumatic drive) can drive the connecting plate 8 and the rack 7 to move. During the movement of the moving end of the rodless cylinder 9, the distance sensor 12 monitors the position of the moving end of the rodless cylinder 9 in real time. Based on the moving position of the moving end of the rodless cylinder 9, the moving distance of the rack 7 can be determined, and the rotation angle of the drive gear 4, the rotating shaft 3, and the bearing platform 5 can also be determined.
