Abstract
Description
Technical Field
[0001] This utility model relates to the field of electric cylinder technology, and specifically to a sliding table type electric cylinder. Background Technology
[0002] In existing sliding table electric cylinders, other components are mounted on the mounting base. The motor assembly drives the piston rod to move, and the piston rod pushes the mounting base to move. Since the piston rod is connected to the end cap at the front end of the mounting base, the mounting base will generate torque around the piston rod during operation, causing wobbling. This affects other components fixed on the mounting base, thus affecting production.
[0003] Therefore, based on the aforementioned shortcomings of existing slide-table electric cylinders, improvements are needed. Utility Model Content
[0004] The purpose of this utility model is to provide a sliding table electric cylinder to address the shortcomings of the existing technology. This sliding table electric cylinder solves the defects of existing electric cylinders, such as the mounting base being prone to shaking.
[0005] To achieve the above objectives, this utility model is implemented through the following technical solution.
[0006] A sliding table type electric cylinder includes a cylinder body and a mounting base. The mounting base is located above the cylinder body, and a slider is mounted on the cylinder body. The mounting base has vertical side edges on both sides, and the two side edges are formed with limit grooves. The limit grooves are opened along the axis of the mounting base, and ball bearings are embedded between the slider and the limit grooves of the mounting base.
[0007] Furthermore, the front and rear ends of the slider are respectively connected to an inner frame, and the two sides of the inner frame protrude outward to form side protrusions. The side protrusions are embedded in the limiting groove of the mounting base, which enables the mounting base to be stably assembled with the inner frame and makes the mounting base move smoothly.
[0008] Furthermore, the outer end of the inner frame is connected to the outer shell, and the two sides of the outer shell protrude outward to form side protrusions. The side protrusions are embedded in the limiting groove of the mounting base, which enables the mounting base to be stably assembled with the inner frame and makes the mounting base move smoothly.
[0009] Furthermore, the slider has inwardly recessed grooves formed on both sides along the axial direction. The ball bearings are embedded between the inner grooves of the slider and the limiting groove of the mounting seat, which enables the ball bearings to be installed better and ensures that the mounting seat moves smoothly.
[0010] Furthermore, the front end face of the inner frame protrudes to form a positioning pin, and the rear end face of the slider is provided with a positioning hole. The positioning pin is inserted into the positioning hole, making the assembly of the slider more convenient and quick.
[0011] Furthermore, the front end face of the inner frame is recessed to form a positioning groove, and the ball is sandwiched between the positioning groove of the front inner frame, the inner groove of the slider, and the positioning groove of the rear inner frame, making the installation of the ball more stable.
[0012] The beneficial effects of this utility model are as follows: when the motor assembly drives the mounting base to move, the mounting base can always maintain stable contact with the ball bearings, which can maintain support for the mounting base on the one hand, and ensure the stability of movement on the other hand.

Detailed Implementation
[0018] The present invention will be further described below with reference to the accompanying drawings.
[0019] See Figure 1 —— Figure 3 This utility model discloses a sliding table type electric cylinder, comprising: a motor assembly 1 and a cylinder body 12. The motor assembly 1 and the cylinder body 12 are fixedly installed. A coupling 2, a rear bearing sleeve 3, a bearing 4, a front bearing sleeve 5, a lead screw nut 6, a lead screw 7, an anti-rotation assembly 8, a piston rod 9, a piston head 10, and a piston sleeve assembly 11 are installed inside the motor assembly 1 and the cylinder body 12. The piston head 10 is connected to an end cover 13, and a mounting seat 14 is connected to the upper rear end of the end cover 13. The mounting seat 14 is located above the cylinder body 12. When the motor assembly 1 is working, it drives the lead screw piston rod 9 to move, thereby moving the mounting seat 14.
[0020] The cylinder body 12 of this utility model is equipped with a slider 15. The two sides of the mounting base 14 are formed with limit grooves. The limit grooves are opened along the axis of the mounting base 14. A ball bearing 17 is embedded between the slider 15 and the limit groove of the mounting base 14. With the setting of the ball bearing, the mounting base 14 can always maintain balance when it moves and can maintain smooth operation.
[0021] The front and rear ends of the slider 15 of this utility model are respectively connected to the outer shell 16 and the inner frame 18 by screws, with the outer shell 16 located at the outer end of the inner frame 18. The outer shell 16 and the inner frame 18 have side protrusions 19 protruding outward on both sides, and the side protrusions 19 are embedded in the limiting groove of the mounting base, so that the movement of the mounting base 14 is balanced.
[0022] The slider 15 of this utility model has inwardly recessed grooves 20 formed on both sides along the axial direction, and the ball bearing 17 is embedded between the inner groove 20 of the slider 15 and the limiting groove of the mounting seat 14.
[0023] The inner frame 18 of this utility model has a protruding positioning pin 21 on its front end face, and a positioning hole is provided on the rear end face of the slider 15, into which the positioning pin 21 is inserted.
[0024] The inner frame 18 of this utility model has a positioning groove 22 recessed on its front end face. The ball bearing 17 is sandwiched between the positioning groove 22 of the front inner frame 18, the inner groove 20 of the slider 15 and the positioning groove 22 of the rear inner frame 18, which can better assemble the ball bearing 17.
[0025] In this invention, the motor assembly 1 drives the piston rod 9 to move, and the piston rod 9 pushes the mounting base 14 to move. The mounting base 14 can make stable contact with the ball bearing 17, ensuring the stability of the movement.
