Description

Technical Field

[0001] The utility model relates to the technical field of planetary reducer series assembly, in particular to a planetary gear quick pressing pin device for a planetary reducer. Background Art

[0002] For a long time, the three pins that fix the planetary gears on the output shaft of the planetary reducer cannot be pressed at the same time, resulting in slow pressing speed, reduced assembly efficiency, and affected delivery time. At the same time, the technical requirements for press workers are also very high, and the positions cannot be flexibly deployed. Therefore, the pressing process has always been one of the biggest problems in assembling planetary reducers.

[0003] The traditional pressing method is to use a lever press and manually press one by one. The assembly and pressing time is long. After placing the output shaft of the reducer into the pressing tool, a planetary gear needs to be placed in the window of the input shaft, and the planetary gear needs to be aligned with the roller hole of the output shaft with a guide rod. The roller is placed in the roller hole, and the tool is placed in the center of the lever manual press, and the roller is pressed into place. This pressing method is cumbersome and time-consuming, and this pressing method has low safety. During the pressing, the operator needs to hold the roller by hand, which poses a safety hazard. In view of this, we need a quick pressing device for planetary gears of planetary reducers. Utility Model Content

[0004] The utility model aims to provide a planetary gear quick pressing pin device for a planetary reducer to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a quick pinning device for planetary gears of a planetary reducer, comprising a base plate, a connecting column is arranged above the base plate, a pressure head is sleeved inside the connecting column, the pressure head and the connecting column are fixed by fixing bolts, a guide shaft is fixedly installed on the outer wall of the base plate, the guide shaft passes through the interior of the upper plate, a load-bearing spring is sleeved on the outer wall of the guide shaft, one end of the load-bearing spring is fixedly connected to the outer wall of the base plate, and the other end of the load-bearing spring is fixedly connected to the bottom wall of the upper plate, and a pinning mechanism is arranged on the base plate.

[0006] Preferably, the pin pressing mechanism comprises a connecting block, the connecting block is fixedly mounted on the outer wall of the bottom plate, and a latch is fixedly mounted on the connecting block.

[0007] Preferably, a positioning block is fixedly mounted on the upper plate, a positioning groove is provided inside the positioning block, and the latch passes through the inside of the positioning groove.

[0008] Preferably, an output shaft is placed on the positioning block, and a guide rod is slidably penetrated inside the output shaft.

[0010] Preferably, a gasket is provided at the end of the guide shaft, and the gasket is fixedly installed at the end of the guide shaft by a fastening bolt.

[0011] Compared with the prior art, the utility model provides a planetary gear quick pressing pin device for a planetary reducer, which has the following beneficial effects:

[0012] 1. The planetary gear quick pressing device for the planetary reducer can save the pressing program formula. The subsequent output shaft pressing only needs to call out the formula and press the switch with both hands at the same time, which greatly improves the assembly efficiency, reduces the operating difficulty of the process and the dependence on the operator's experience, and reduces the fluctuation of the assembly quality of the same batch of parts.

[0013] 2. The planetary gear quick pressing pin device for the planetary reducer can press-fit three groups of rollers at the same time by setting the positioning groove in the pressing pin mechanism, eliminating the safety hazard of workers holding the rollers with their hands and improving work efficiency.

DETAILED DESCRIPTION

[0019] like Figure 1-Figure 4As shown, the utility model provides a technical solution: a planetary gear quick pressing pin device for a planetary reducer, comprising a base plate 1, a connecting column 9 is arranged above the base plate 1, a pressing head 10 is sleeved inside the connecting column 9, the pressing head 10 is driven by the connecting column 9 to move downward to press the output shaft 75 downward to complete the pressing work, the pressing head 10 and the connecting column 9 are fixed by fixing bolts 11, a guide shaft 2 is fixedly installed on the outer wall of the base plate 1, the guide shaft 2 passes through the interior of the upper plate 3, a gasket 5 is arranged at the end of the guide shaft 2, the gasket 5 is fixedly installed on the end of the guide shaft 2 by fastening bolts 6, a load-bearing spring 4 is sleeved on the outer wall of the guide shaft 2, one end of the load-bearing spring 4 is fixedly connected to the outer wall of the base plate 1, and the other end of the load-bearing spring 4 is fixedly connected to the bottom wall of the upper plate 3, the upper plate 3 can be driven to move upward for reset by the elastic force of the load-bearing spring 4, so as to facilitate re-pressing, and a pressing pin mechanism 7 is arranged on the base plate 1.

[0020] In this embodiment, a pinning mechanism 7 is provided on the base plate 1. Through the setting of the positioning grooves in the pinning mechanism 7, three groups of rollers can be pressed at the same time, eliminating the safety hazard of workers holding the rollers with their hands and improving work efficiency.

[0021] The above-mentioned pin pressing mechanism 7 includes a connecting block 71, which is fixedly mounted on the outer wall of the base plate 1, a latch 72 is fixedly mounted on the connecting block 71, and a positioning block 73 is fixedly mounted on the upper plate 3. A positioning groove is provided inside the positioning block 73, and a roller to be pinned is placed inside the positioning groove for press-fitting. The latch 72 passes through the inside of the positioning groove, and the roller is supported by the latch 72 inside the positioning groove, so that the roller can be press-fitted into the inside of the planetary gear 8. An output shaft 75 is placed on the positioning block 73, and a guide rod 76 is slidably penetrated inside the output shaft 75, and the planetary gear 8 can be fixed by the guide rod 76. A window 77 is provided inside the output shaft 75, and the planetary gear 8 is placed inside the window 77 inside the output shaft 75 for press-fitting. The planetary gear 8 is placed inside the window 77.

[0022] After the pressing is completed, the connecting column 9 drives the pressing head 10 to move upward and no longer press the output shaft 75, and the output shaft 75 drives the bottom of the bottom positioning block 73 to move downward. Finally, the roller is supported by the pin 72 in the positioning groove and is pressed into the interior of the planetary gear 8. When the guiding rod 76 is pushed out by the roller, the roller is pressed into place. At this time, the pressing program formula is saved, and the subsequent press-fitting of the output shaft 75 only needs to call out the formula, and the press-fitting can be performed by pressing the switch with both hands at the same time. After the press-fitting is completed, the connecting column 9 drives the pressing head 10 to move upward and no longer squeezes the output shaft 75. The elastic force of the load-bearing spring 4 drives the upper plate 3 to move upward for reset, which is convenient for pressing again.

Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
