Screw rod drive push rod device with embedded guide rail

Abstract

The invention provides a screw rod drive push rod device with an embedded guide rail. The screw rod drive push rod device with the embedded guide rail comprises a base, wherein a sliding chute is formed in the base; a slide rail is arranged on the sliding chute; a ball screw is arranged in the base and comprises a push rod; a sliding block is connected onto the push rod; reversers are arranged onthe sliding block; a circulating channel is arranged between the reversers; steel balls are arranged in the circulating channel and are matched with the slide rail; a screw rod nut is arranged in thesliding block; a screw rod is connected onto the screw rod nut, rightwards penetrates through the sliding block so as to extend into the push rod, and leftwards penetrates through first bearings so asto be connected with a coupler; the coupler is connected with a motor; a second baffle plate is arranged at the left end of the base; the push rod penetrates through the second baffle plate so as tobe connected with a connector; and a second bearing is arranged between the second baffle plate and the push rod. The screw rod drive push rod device with the embedded guide rail provided by the invention is simple in structure and convenient and rapid to use; and with the unique design of the embedded guide rail, no riveted fixing is needed, so that the service life is effectively prolonged, theprocessing cost is saved, and the later-period maintenance can be carried out conveniently.

Description

technical field [0001] The invention relates to an automatic production line, in particular to a guide rail embedded screw drive push rod device. Background technique [0002] The existing technical solutions mainly include the embedded guide rail rolling guide represented by Japan's IAI and Taiwan's TOYO, and other manufacturers' solutions by installing mechanical anti-rotation on the push rod; the existing embedded guide rail solution is the motor The ball screw is connected to the ball screw through a coupling, and the rotation of the motor drives the ball screw to rotate; in order to convert the rotary motion into a linear motion, the screw rotates while restricting the rotation of the screw nut, and this solution is embedded in the profile Guide rail, and cooperate with the upper guide rail groove of the push rod slide seat (the inner sleeve has a screw nut), and balls are installed between the guide rail grooves to eliminate the backlash and now the screw nut rotates, ...

AI Technical Summary

Problems solved by technology

For the processing of the rod slider, IAI uses the same method as the base, and the guide rail is embedded and riveted before grinding, while TOYO is grinding on the rod slider (no additional guide rail is installed); now There are technical disadvantages: first, the embedded guide rail on the base needs to be riveted and fixed after installation, which increases the assembly process and increases the assembly cost; second, after the embedded guide rail is embedded, it needs to be ground again , this process is more difficult to process and clamp, especially for the push rod cylinder with a longer stroke, the processing is more difficult; third, in order to process after the base is embedded in the guide rail, the base profile cannot be made into a single closed profile, The cylinder body needs to be split into upper and lower halves. Compared with a single closed profile, this structure increases the types of profiles, increases the amount of machining, increases the workload of assembly, reduces the overall rigidity of the finished product, and increases the sealing application of the product. Difficulty; Fourth, the push rod cylinder with this structure is embedded in the guide rail and the push rod of the push rod cylinder is arranged eccentrically, which finally makes the performance of the push rod different in each direction
