[0002] The planetary shaft of the reducer is mainly used in the reduction box to install and position the planetary gears. In order to increase the service life of the bearings installed on the planetary shaft, lubrication channels are usually drilled on the planetary shaft to facilitate the circulation of lubricating oil and increase the lubrication of the bearings.

[0003] In the process of implementing this application, it was found that the technology has the following problems: most of the existing reducer planetary core shaft positioning and clamping devices are irregular in shape, which requires the staff to use multiple sets of positioning parts when positioning the core shaft, which in turn makes the subsequent staff spend a long time in installing and removing the core shaft, thus reducing the practicality of the equipment.

[0004] For this purpose, a planetary spindle positioning and clamping device for a reducer is proposed. Utility Model Content

[0005] The purpose of the utility model is to solve the problem that most of the existing planetary mandrel positioning and clamping devices for reducers are of irregular shapes, which requires the staff to use multiple sets of positioning parts when positioning the mandrel, and thus causes the subsequent staff to spend a long time in installing and removing the mandrel. The utility model provides a planetary mandrel positioning and clamping device for reducer.

[0008] Furthermore, the positioning mechanism includes a motor and four groups of fixed rods, the motor is installed at the bottom of the inner wall of the U-shaped base, the output shaft of the motor is installed with gear 2, the four groups of fixed rods are respectively rotatably connected to the four groups of through holes in the U-shaped base, the lower surfaces of the four groups of fixed rods are installed with gear 1, the external teeth of the four groups of gear 1 are meshed and connected to the external teeth of gear 2, the outer surfaces of the four groups of fixed rods are installed with limit plates, and the four groups of limit plates are installed with arc-shaped limit blocks on the side away from the adjacent group of fixed rods.

[0009] Furthermore, a fixed ring is installed on the upper surface of the U-shaped base, the axis of the fixed ring is parallel to the axis of the gear 2, and the inner contour of the fixed ring is matched with the outer contour of the positioning spindle base of the positioning mechanism.

[0010] Furthermore, the upper surfaces of the four groups of arc-shaped limit blocks are all in contact with the upper surface of the fixed ring.

[0011] Furthermore, the protective mechanism includes two groups of guide rails, which are respectively installed on the front and rear sides of the U-shaped base, and the insides of the two groups of guide rails are slidably connected with baffles, and side panels are installed between adjacent sides of the two groups of baffles.

The utility model starts a motor to drive gear two, four sets of gear one and four sets of fixed rods to rotate, and makes the four sets of arc-shaped limit blocks abut against the four side outer surfaces of the core shaft on the side away from the adjacent set of fixed rods, so that the four sets of limit plates and the four sets of arc-shaped limit blocks can position the position of the core shaft at the upper end of the U-shaped base, and then the positioning mechanism can position the position of the core shaft by a card-connection manner, so that subsequent staff can quickly use the device to install and disassemble the core shaft, thereby shortening the time and labor consumed by subsequent staff when using the device to detect or maintain the core shaft, thereby improving the practicality of the device.

[0015] 2.

[0025] like Figures 1 to 4As shown, a planetary mandrel positioning and clamping device for a reducer comprises a U-shaped base 1, the upper surface of the U-shaped base 1 is provided with four groups of through holes, the four groups of through holes of the U-shaped base 1 are rotatably connected with a positioning mechanism 3, the lower surface of the positioning mechanism 3 is mounted on the bottom of the inner wall of the U-shaped base 1, and the front and rear sides of the U-shaped base 1 are provided with a protective mechanism 2 for shielding and protecting the positioning mechanism 3; specifically, by starting the positioning mechanism 3, the mandrel is positioned at the upper end of the U-shaped base 1, so that the positioning mechanism 3 uses a clamping method to position the position of the mandrel, thereby This enables subsequent staff to quickly use the device to install and disassemble the core shaft, thereby shortening the time and labor spent by subsequent staff when using the device to detect or maintain the core shaft, thereby improving the practicality of the device; the protective mechanism 2 is used to shield and protect the partial structure of the positioning mechanism 3 inside the groove of the U-shaped base 1, thereby minimizing the possibility that the staff's hands and the positioning mechanism 3 are in contact with the partial structure inside the groove of the U-shaped base 1 when the staff is operating the device, thereby minimizing the possibility that the staff's hands will be injured, thereby improving the safety of the device during use.

[0026] like Figure 1 , Figure 2 and Figure 4 As shown, the positioning mechanism 3 includes a motor 301 and four groups of fixed rods 303, the motor 301 is installed at the bottom of the inner wall of the U-shaped base 1, the output shaft of the motor 301 is installed with a gear 2 306, the four groups of fixed rods 303 are respectively rotatably connected to the inside of the four groups of through holes of the U-shaped base 1, the lower surfaces of the four groups of fixed rods 303 are all installed with gears 1 302, the external teeth of the four groups of gears 1 302 are all meshed and connected to the inside of the external teeth of gear 2 306, the outer surfaces of the four groups of fixed rods 303 are all installed with limit plates 304, and the sides of the four groups of limit plates 304 away from the adjacent group of fixed rods 303 are all installed with arc-shaped limit blocks 305;

[0027] Specifically, when the core shaft is placed on the upper surface of the U-shaped base 1 and is located between the four groups of arc-shaped limit blocks 305, the motor 301 is started to drive gear 2 306, four groups of gear 1 302 and four groups of fixed rods 303 to rotate, and the four groups of arc-shaped limit blocks 305 are abutted against the four side outer surfaces of the core shaft away from the adjacent group of fixed rods 303, so that the four groups of limit plates 304 and four groups of arc-shaped limit blocks 305 can position the position of the core shaft at the upper end of the U-shaped base 1, and then the positioning mechanism 3 can position the position of the core shaft by a clamping manner, so that subsequent staff can quickly use the device to install and disassemble the core shaft, thereby shortening the time and labor consumed by subsequent staff when using the device to detect or maintain the core shaft, thereby improving the practicality of the device.

[0028] like Figure 2As shown, a fixed ring 4 is installed on the upper surface of the U-shaped base 1, the axis of the fixed ring 4 is parallel to the axis of the gear 2 306, and the inner contour of the fixed ring 4 is matched with the outer contour of the positioning spindle base of the positioning mechanism 3; specifically, before the four groups of arc-shaped limit blocks 305 position the spindle, the spindle is pushed and clamped in the inside of the fixed ring 4, so that the fixed ring 4 quickly positions the spindle between the four groups of arc-shaped limit blocks 305, so that the staff can quickly install the spindle to the positioning area, thereby shortening the time spent by subsequent staff on positioning the spindle, thereby improving the practicality of the device.

[0029] like Figure 1 and Figure 2 As shown, the upper surfaces of the four groups of arc limit blocks 305 are all in contact with the upper surface of the fixed ring 4; specifically, when the four groups of arc limit blocks 305 are in contact with the outer surface of the core shaft on one side away from the adjacent group of fixed rods 303, the positions of the four groups of arc limit blocks 305 are set at the upper ends of the fixed ring 4 and the core shaft base, so that the four groups of arc limit blocks 305 limit the position of the core shaft moving upward inside the fixed ring 4, thereby minimizing the subsequent upward movement of the core shaft inside the fixed ring 4 during inspection or maintenance.

[0030] like Figures 1 to 3 As shown, the protection mechanism 2 includes two sets of guide rails 201, which are respectively installed on the front and rear sides of the U-shaped base 1, and the insides of the two sets of guide rails 201 are slidably connected with baffles 202, and a side plate 204 is installed between the adjacent sides of the two sets of baffles 202. A control panel 203 is arranged on the front side of the front set of baffles 202, and the control panel 203 is electrically connected to the control end of the motor 301. A push plate 205 is installed on the upper surface of the side plate 204, and the push plate 205 is located at the upper end of the U-shaped base 1.

[0031] Specifically, the two groups of baffles 202 are driven to slide inside the two groups of guide rails 201 by pushing the side plate 204, and the positions of the two groups of baffles 202 are moved to the front and rear sides of the U-shaped base 1, so that the protective mechanism 2 shields and protects the partial structure of the positioning mechanism 3 inside the groove of the U-shaped base 1, thereby avoiding as much as possible the contact between the hands of the staff and the partial structure of the positioning mechanism 3 inside the groove of the U-shaped base 1 when the staff operates the device, thereby improving the safety of the device during use; the side plate 204 and the two groups of baffles 202 are driven to move by pulling the push plate 205, so that the staff can quickly pull the two groups of baffles 202 to move, thereby shortening the time spent by subsequent staff in maintaining the partial structure of the positioning mechanism 3 inside the groove of the U-shaped base 1, thereby improving the practicality of the device during use.

[0032] At the same time, when the protective mechanism 2 blocks the motor 301, the motor 301 is started by operating the control panel 203, so that the staff does not need to adjust the position of the mobile protective mechanism 2 during the process of starting the motor 301, thereby reducing the labor consumed by subsequent staff in the process of starting the motor 301 and starting the positioning mechanism 3.

[0033] like Figure 2 and Figure 3 As shown, an insertion rod 5 is provided on the side of the side plate 204 close to the positioning mechanism 3, and a slot is provided on the side of the U-shaped base 1 close to the protective mechanism 2, and the position of the slot is located on the moving path of the insertion rod 5; specifically, by pushing the protective mechanism 2, the insertion rod 5 is clamped in the slot of the U-shaped base 1, so that the insertion rod 5 limits the moving position of the two groups of baffles 202 on the front and rear sides of the U-shaped base 1, thereby avoiding as much as possible the subsequent movement of the protective mechanism 2 during use, which causes the protective mechanism 2 to be unable to shield and protect part of the internal structure of the positioning mechanism 3.

[0034] In summary: by starting the motor 301 to drive the gear 2 306, the four groups of gears 1 302 and the four groups of fixed rods 303 to rotate, the four groups of arc limit blocks 305 are abutted against the four side outer surfaces of the core shaft away from the adjacent group of fixed rods 303, so that the four groups of limit plates 304 and the four groups of arc limit blocks 305 can position the position of the core shaft at the upper end of the U-shaped base 1, and then the positioning mechanism 3 uses a clamping method to position the position of the core shaft, so that subsequent staff can quickly use the device to install and disassemble the core shaft; by pushing the core shaft, the core shaft is clamped inside the fixed ring 4, so that the fixed ring 4 quickly positions the core shaft between the four groups of arc limit blocks 305, so that the staff can quickly install the core shaft to the positioning area.

[0035] At the same time, by pushing the side panels 204, the two groups of baffles 202 are driven to slide inside the two groups of guide rails 201, and the positions of the two groups of baffles 202 are moved to the front and rear sides of the U-shaped base 1, so that the protective mechanism 2 shields and protects the partial structure of the positioning mechanism 3 inside the groove of the U-shaped base 1, thereby minimizing the possibility that the hands of the staff and the positioning mechanism 3 contact the partial structure inside the groove of the U-shaped base 1 when the staff operates the device, causing injuries to the hands of the staff; the motor 301 is started by operating the control panel 203, so that the staff does not need to adjust the position of the mobile protective mechanism 2 during the process of starting the motor 301.
