Abstract
Description
Technical Field
[0001] The utility model relates to a servo electric cylinder lifting platform, belonging to the field of workpiece lifting drive. Background Art
[0002] The existing technologies for moving the workpiece up and down are all through the air cylinder and oil cylinder methods. The distance dimension accuracy cannot be guaranteed through these methods, and when the air pressure and oil pressure are unstable, the lifting will be unstable and jammed. These methods of ejection also require the addition of a limit device to prevent shaking and instability caused by complete ejection, which increases the processing cost. Another existing technology is a lifting platform connected by a linear motor. Since the linear motor is connected to a ball bearing, the overall precision dimension can only reach 0.01mm, which cannot meet the high-precision requirements. Utility Model Content
[0003] In order to overcome the defects of the prior art, the utility model provides a servo electric cylinder lifting platform. The technical solution of the utility model is:
[0004] A servo electric cylinder lifting platform comprises a base plate, a servo electric cylinder, a guide column, a platform plate and a pressure plate. The servo electric cylinder is installed on the base plate and is arranged in a horizontal direction. Several guide columns are arranged on the base plate adjacent to the servo electric cylinder. Each of the guide columns is slidably matched with the base plate through a linear bearing. The platform plate is installed on the upper end of the guide column, and the pressure plate is installed on the platform plate. A lifting guide unit is installed on the base plate under the platform plate, and the lifting guide unit is driven by the servo electric cylinder.
[0005] The lifting guide unit includes a slide plate, a slider, a roller and a roller frame. The slide plate is slidably installed on the base plate, and the slider is fixedly installed on the slide plate and reciprocates on the base plate with the slide plate; the upper end surface of the slider forms a guide slope; a roller frame is installed at the lower part of the carrier plate, and the roller is rotatably installed on the roller frame and rollingly cooperates with the guide slope.
[0006] The servo electric cylinder is installed on the base plate through a baffle.
[0007] It also includes a pull rod, one end of which is transmission-connected to the driving end of the servo electric cylinder, and the other end of which is connected to the sliding block.
[0008] Side plates are installed on the bottom plates at both sides of the slider, and the side plates are used to guide the slider.
[0009] A supporting column is installed at the bottom of the base plate.
[0010] The advantages of the utility model are: the drive is achieved through a servo electric cylinder, and this servo electric cylinder adopts a screw with a five-head nut and a tap with a five-head nut. The overall accuracy and transmission ratio rate are increased and stable, and the accuracy of the linear transmission runout value can reach 0002mm. The material used for the slider components in the lifting platform of this servo electric cylinder is tungsten steel. Due to the high wear resistance of tungsten steel, the service life of the overall tooling is greatly extended. The guide connection of the guide column in the up and down directions uses high-precision linear bearings. The overall up and down movement is smoother and the accuracy is guaranteed. The carrier plate in the tooling parts can be changed in style according to actual needs to meet the needs of different productions, and the application surface is wider.

[0014] The present invention is further described below in conjunction with specific embodiments, and the advantages and features of the present invention will become clearer as the description proceeds. However, these embodiments are merely exemplary and do not constitute any limitation to the scope of the present invention. It should be understood by those skilled in the art that the details and forms of the technical solution of the present invention may be modified or replaced without departing from the spirit and scope of the present invention, but these modifications and replacements fall within the scope of protection of the present invention.
[0015] See also Figures 1 to 3 The utility model relates to a servo electric cylinder lifting platform, including a base plate 11, a servo electric cylinder 1, a guide column 5, a platform plate 4 and a pressure plate 3. The servo electric cylinder 1 is installed on the base plate 11, and the servo electric cylinder 1 is arranged in a horizontal direction. A plurality of guide columns 5 are arranged on the base plate 11 adjacent to the servo electric cylinder 1. Each of the guide columns 5 is slidably matched with the base plate 11 through a linear bearing 6. The platform plate 4 is installed at the upper end of the guide column 5, and the pressure plate 3 is installed on the platform plate 4. A lifting guide unit is installed on the base plate 11 at the lower part of the platform plate 4, and the lifting guide unit is driven by the servo electric cylinder 1.

The slide plate 9 is slidably installed on the base plate 11, and the slider 8 is fixedly installed on the slide plate 9 and reciprocates on the base plate 11 with the slide plate 9; the upper end surface of the slider 8 forms a guide slope; a roller frame is installed at the lower part of the carrier plate 4, and the roller 13 is rotatably installed on the roller frame and rollingly cooperates with the guide slope.
[0017] The servo electric cylinder 1 is mounted on the base plate 11 through a baffle 10 .
[0018] It also includes a pull rod 2, one end of which is transmission-connected to the driving end of the servo electric cylinder 1, and the other end of which is connected to the slider 8.

[0021] The working principle of the utility model is: place the workpiece to be lifted on the carrier plate, energize the servo electric cylinder, and drive the pull rod to move through the servo electric cylinder, thereby driving the slider to move. When the pull rod drives the slider, the roller on the upper part of the slider and the side plate make the slider move back and forth. The starting position of the roller is at the high end of the guide inclined surface. When the pull rod drives the slider to move back and forth, the upper roller rotates, and the slider moves to the inclined surface angle position, the roller and the carrier plate descend together, and the carrier plate is moved up and down through the cooperation of the linear bearing and the guide column, thereby realizing the precise up and down distance lifting and lowering movement of the workpiece.
