Problems solved by technology

The traditional high-thrust high-speed electric cylinder has the following defects: first, the thrust is small, the thrust is limited and the thrust is difficult to reach more than 35 tons, the price is expensive and the cost of use is high; second, the structure is complex, and the screw or screw nut is prone to damage. free rotation
[0004] Although the above-mentioned scheme has the above advantages, there are at least the following defects in this scheme: the above-mentioned low thrust and the technical problems that the screw mandrel or the screw nut are prone to free rotation cannot be improved, and the practicability is poor.

Embodiment 1

[0033] Such as figure 1 and Figure 3-4 As shown, the high-thrust high-speed electric cylinder includes a cylinder body 1 with a chamber 1a, on the cylinder body 1 there are at least two driving rods 2 respectively pierced in the chamber 1a and parallel to each other, and the driving rods 2 are evenly distributed And the two ends of each driving rod 2 are respectively pierced through the two ends of the cylinder body 1, and the driving rod 2 is connected with the cylinder body 1 in rotation. A positioning blind hole is provided inside one end of the cylinder body 1, and one end of the driving rod 2 is inserted into the positioning blind hole and a first fixing seat 21 is provided between the positioning blind hole and the driving rod 2, and at the other end of the cylinder body 1 Several positioning through holes are provided, and a second fixing seat is arranged in the positioning through holes, and the other end of the driving rod 2 extends to the outside of the cylinder bo...

Embodiment 2

[0044] Such as Figure 7 As shown, the structure and principle of this embodiment are basically the same as those of Embodiment 1, so we won’t repeat them here. The drive ring gear 54 is connected to the driving device 55 capable of driving the drive ring gear 54 to rotate. The driving device 55 here includes a multi-point meshing flexible transmission connected to the driving ring gear 54 . The structure of the multi-point meshing flexible transmission device is a prior art, so no further details will be given here.

[0045] By driving the rotation of the ring gear 54 to drive multiple planetary gears 51 to rotate simultaneously, the consistency of power output is ensured.

Embodiment 3

[0047] Such as Figure 8 As shown, the structure and principle of the present embodiment are basically the same as those of the second embodiment, and will not be described in detail here. The difference is that the drive device 55 includes a plurality of drive gears 55a that are meshed with the drive ring gear 54 respectively. , the drive gear 55a is connected to the driver 55b. The driver 55b is a drive motor.

Abstract

The invention belongs to the mechanical power source technical field and relates to a large-thrust high-speed electric cylinder. With the large-thrust high-speed electric cylinder of the invention adopted, technical problems such as low thrust and low practicability in the prior art can be solved. The large-thrust high-speed electric cylinder comprises a cylinder body with a chamber; the cylinder body is provided with at least two driving rods which pass through the chamber and are parallel to each other; a push plate which is connected with the driving rods is arranged in the chamber; a connection structure which can drive the push plate to move in a reciprocating manner along the axial direction of the driving rods when the driving rods rotate is arranged between the driving rods and the push plate; the push plate is provided with at least one push rod which can move relative to the cylinder body; and the driving rods are connected with a driving mechanism which can drive the driving rods to rotate synchronously. Compared with the prior art, the large-thrust high-speed electric cylinder of the invention has the advantages large thrust and high practicability.

Description

technical field [0001] The invention belongs to the technical field of precision mechanical power sources, and in particular relates to a high-thrust high-speed electric cylinder. Background technique [0002] The high-thrust high-speed electric cylinder is a mechanical device that can generate a power source, and is currently widely used in mechanical equipment in various fields. For example: automatic servo injection molding machines and presses and other mechanical equipment. The structure of the traditional large-thrust high-speed electric cylinder includes a cylinder body and a screw rod installed in the cylinder body. A screw nut is set on the screw rod. The screw nut is connected to the piston rod. The drive motor drives the screw rod to rotate. The nut walks on the screw rod to make the piston rod move, and an anti-rotation guide groove is provided in the cylinder body to prevent the screw nut from rotating. The traditional high-thrust high-speed electric cylinder ...
