Detailed Description
The utility model is explained in further detail below with reference to the figures and the specific embodiments.
As shown in fig. 1-4, a lifting platform for machining includes a table top 1, fixed cylinders 2, screw sleeves 3, transmission sprockets 4, screws 5, a base 6, anti-slip pads 7, chains 8, and a transmission device 9, wherein four fixed cylinders 2 are fixed at four corners of the bottom of the table top 1, the screw sleeves 3 rotate in the fixed cylinders 2, the transmission sprockets 4 are fixed on the outer walls of the screw sleeves 3, the screws 5 are in threaded fit with the bottom of the screw sleeves 3, the base 6 is fixed at the bottom of the screws 5, the anti-slip pads 7 are bonded on the bottom surface of the base 6, the chains 8 are mounted on the four transmission sprockets 4 to enable the four transmission sprockets to rotate synchronously, and the transmission device 9 is mounted below the table top 1 in front of the chains 8.
The transmission device 9 comprises a shaft sleeve 10, a rotating shaft 11, a driving chain wheel 12, a rotating handle 13, a fixing plate 14, an adjusting screw rod 15 and a rotating handle 16, the shaft sleeve 10 is provided with the rotating shaft 11 at the bottom of the shaft sleeve 10, the driving chain wheel 12 is fixed on the outer wall of the rotating shaft 11, the rotating handle 13 is fixed at the bottom of the rotating shaft 11, the fixing plate 14 is fixed with the table board 1, the adjusting screw rod 15 is in threaded fit with the fixing plate 14, the rear end of the adjusting screw rod 15 rotates along the outer wall of the shaft sleeve 10, and the rotating handle 16 is fixed at the front end of the adjusting screw rod 15.
