As shown in fig. 1, a lifting structure 10 applied to a lifting table includes: a mounting bracket 11 and a motor 12. The mounting rack 11 is fixedly mounted on a table plate of the lifting table. The motor 12 is mounted in the mounting frame 11. The lifting structure 10 applied to the lifting table further comprises: driving claw 15, driving head 16, driving pipe 17, sleeve 18, lifting nut 19 and lifting screw 20. One end of the elevating screw 20 is rotatably connected to the leg of the elevating table. The specific structure is as follows:
a first hexagonal hole 121 is formed in the motor 12. The hexagonal mandrel 13 is arranged in the first hexagonal hole 121. The hexagonal mandrel 13 is matched with the first hexagonal hole 121, the installation error of the transmission structure in the radial direction is small, the transmission precision is high, and no clearance exists in the transmission structure in the radial direction.
The driving dog 15 is rotatably connected to the mounting frame 11, and the driving head 16 is connected to the driving dog 15. The driving pawl 15 is formed in a second hexagonal hole 151 for fitting the hexagonal spindle 13. One end of the hexagonal mandrel 13 is inserted into the second hexagonal hole 151 formed by the driving claw 15 to drive the driving claw 15 to rotate relative to the mounting frame 11, so as to drive the driving head 16 to rotate. The hexagonal mandrel 13 and the second hexagonal hole 151 are matched to drive the transmission structure of the transmission claw 15, the transmission precision is high, and the transmission structure does not have a gap in the radial direction.
The transmission pipe 17 is sleeved on the outer periphery of the elevating screw 20 and connected to the transmission head 16. At the same time, the drive tube 17 drives the lifting spindle 20 by means of a toothed engagement. Specifically, one end of the transmission pipe 17 is connected to the transmission head 16 through a tooth engagement and the other end is connected to the lift screw 20 through a tooth engagement, that is, the transmission pawl 15 and the lift screw 20 are each formed with external teeth. The drive head 16 is formed with internal teeth for mating with the external teeth. The transmission head 16 is sleeved on the periphery of the transmission claw 15 and is connected to the transmission claw 15 in a follow-up manner through meshing of internal teeth and external teeth. Meanwhile, the driving head 16 is sleeved on the outer periphery of the lifting screw 20, and the lifting screw 20 is connected to the driving head 16 by the engagement of the outer teeth of the lifting screw 20 and the inner teeth of the driving head 16. Thus, when the driving head 16 rotates, the driving pipe 17 is driven to rotate, so that the lifting screw 20 is driven to rotate relative to the leg of the lifting table through the teeth meshed with the driving pipe. Also, the lifting screw 20 is driven to rotate by the transmission pipe 17 in a tooth meshing manner, so that the transmission precision is high, and a gap in the radial direction can be avoided.
The lifting nut 19 is screwed on the outer periphery of the lifting screw 20. The sleeve 18 is sleeved on the periphery of the transmission pipe 17, and one end of the sleeve is connected with the lifting nut 19 and the other end of the sleeve is connected with the mounting frame 11. When the elevating screw 20 is rotated, the elevating nut 19 is driven to move up and down in the extending direction of the elevating screw 20. The lifting nut 19 can drive the sleeve 18 to move up and down when moving up and down, so as to drive the table plate of the lifting table positioned at the upper end of the sleeve 18 to move up and down, thereby realizing the lifting function.
Specifically, the overall transmission structure in the above-mentioned case has no gap in the radial direction, and the occurrence of idle rotation and impact of the transmission structure due to the gap caused by the load can be avoided.
As a specific embodiment, the drive head 16 is formed with a threaded bore 161. One end of the hexagonal spindle 13 passes through the driving pawl 15 and is screwed into the threaded hole 161. Such structure makes hexagon dabber 13, driving pawl 15 and transmission head 16 become a whole, can not take place axial float between the three to guarantee the ascending installation accuracy of axial, thereby guarantee the ascending transmission accuracy of axial.
Further, one end of the hexagonal mandrel 13 is also threaded with a limit nut 14. The limit nut 14 presses the drive head 16 from the side of the drive head 16 remote from the drive pawl 15. This further ensures the accuracy of the axial fit between the hexagonal socket 13, the driving pawl 15 and the driving head 16.
As a specific embodiment, one end of the sleeve 18 is fixed to the mounting bracket 11 by welding, and the structural stability is high. The drive head 16 is also formed with a retaining ring 21. The retainer 21 serves to limit the axial position of the sleeve 18 from one end of the sleeve 18 to prevent play of the sleeve 18 in the axial direction. The inner side surface of the sleeve 18 is formed with a limit groove 182 for receiving the retainer ring 21.
Further, the other end of the sleeve 18 is fixedly connected to the outer circumference of the lifting nut 19 by a shaft pin. Such a connection structure is high in structural stability in the axial direction.
Further, the lifting nut 19 is formed with an interference step 191. The sleeve 18 is formed with a mating step 181. The engagement step 181 is for engaging the interference step 191. The interference step 191 is for interfering with the engagement step 181 of the one end of the sleeve 18 to prevent the sleeve 18 from moving axially, and also to move the sleeve 18 up and down from below the sleeve 18 by the interference force. The structure is simple and the reliability is high.
Particularly, the utility model provides a be applied to elevation structure 10 of lift table can avoid elevation structure's whole emergence axial float, and axial stability is stronger.
