一种轴系拼装结构

Abstract

本实用新型公开了一种轴系拼装结构，包括托盘、输入轴定位座、输出轴定位座以及中间轴定位座，输入轴定位座固定在托盘上，装有输入齿轮的输入轴由输入轴定位座支撑并可在输入轴定位座上转动，输出轴定位座固定在托盘上，装有输出齿轮的输出轴由输出轴定位座支撑并可在输出轴定位座上转动，中间轴定位座设置在托盘上，装有中间齿轮的中间轴由中间轴定位座支撑，并且中间轴定位座可以使中间轴朝向输入轴定位座与输出轴定位座之间移动。本实用新型在拼装时，输入轴和输出轴均为固定位置，只有中间轴可以移动，相较于现有技术，本实用新型减少移动部件的数量，结构更简单，更方便轴系的拼装。

2. The shafting assembly structure according to claim 1, characterized by Intermediate shaft positioning seat includes The mounting base is fixed to the tray; The guide rail is fixed on the tray, with one end facing the fixed base and the other end facing the direction between the input shaft positioning base and the output shaft positioning base; Sliding seat A is set on the guide rail and can slide along the length of the guide rail. Sliding seat A is provided with intermediate shaft support A, which can rotate relative to sliding seat A and is used to support the intermediate shaft from the bottom when in use. One or more guide rods A, one end of which is fixedly connected to the sliding seat A, and a spring A is fitted on each guide rod A; Sliding seat B, the other end of guide rod A passes through sliding seat B, sliding seat B and guide rod A can slide relative to each other, and a stop is set at the end of guide rod A, the two ends of spring A abut against sliding seat A and sliding seat B respectively; and The blocking block is set on the fixed base and can move vertically relative to the fixed base. The blocking block is used to prevent the sliding block B from moving towards the sliding block A. The blocking block moves downward to release the obstruction of the sliding block B.

3. The shafting assembly structure according to claim 2, characterized by The intermediate shaft positioning seat also includes Guide rod B, one end of which is fixed to sliding seat A, and the other end passes through fixed seat and can slide relative to fixed seat; and Spring B is sleeved on guide rod B, with its two ends abutting against sliding seat A and fixed seat respectively.

4. The shaft assembly structure according to claim 2, characterized in that, There are two blocking blocks. Two lifting slots are opened on the fixed base. At each end of the fixed base, there is a waist-shaped hole communicating with the lifting slot. The two blocking blocks are respectively set in the two lifting slots. A pressure rod is fixed on the side of the blocking block facing the waist-shaped hole. The pressure rod extends out of the waist-shaped hole. At least one spring C is set at the bottom of the blocking block. When the pressure rod is pressed down, the blocking block moves down. When the pressure rod is released, the spring C pushes the blocking block up.

5. The shaft assembly structure according to claim 2, 3, or 4, characterized in that, The top of the blocking block has a trapezoidal weight-reducing groove that runs through both sides of the blocking block.

6. The shaft assembly structure according to claim 2, 3, or 4, characterized in that, It also includes an intermediate shaft support B, which is fixed to the sliding seat B and is used to support the intermediate shaft from the bottom during use.

7. The shaft assembly structure according to claim 2, characterized in that, It also includes an anti-collision buffer device, which is set on the tray and located at the other end of the guide rail, and is used to abut against the slide seat A to provide cushioning for the sliding of the slide seat A when the slide seat A moves.

8. The shafting assembly structure according to claim 1, characterized by Input shaft positioning seat includes The mounting base body A is fixed on the tray; as well as The support sleeve is rotatably mounted inside the fixed base. In use, the bottom end of the input shaft extends into the support sleeve and is supported by the support sleeve.

9. The shafting assembly structure according to claim 1, characterized by Output shaft positioning seat includes The mounting base body B is fixed on the tray; as well as The output shaft support is rotatably mounted inside the fixed base body B and is used to support the output shaft from the bottom when in use.

10. The shaft assembly structure according to claim 1, characterized in that, Also includes Multiple bearing supports are used to hold the bearings to be installed on the input shaft, output shaft, and intermediate shaft during use.
