Description

Technical Field

[0001] The utility model belongs to the technical field of electric cylinders, and particularly relates to a micro slide table electric cylinder with an easily replaceable slide table. Background Art

[0002] When replacing the slide table of a slide table electric cylinder, it is often necessary to disassemble multiple connecting components. This process is not only cumbersome but also consumes a lot of time, resulting in a long replacement cycle and inability to quickly resume production. The main reasons for this problem include the unreasonable structural connection method between the slide table and the electric cylinder. Most traditional slide table electric cylinders adopt a fixed design. Each replacement not only requires the disassembly of the slide table itself but also requires appropriate adjustment of the surrounding equipment.

[0003] Conventional countermeasures include designing a more convenient disassembly connection method, such as using quick connectors to replace the slide table. However, these methods also have certain disadvantages. Although using quick connectors can improve the replacement efficiency, it may reduce the connection stability, resulting in loosening under high-load operations. Therefore, we hope to design a slide table electric cylinder with a new structure to solve this problem. Summary of the Utility Model

A second threaded hole is opened downward at the bottom of each positioning hole, and the inner wall of the positioning hole is designed to be smooth. The diameter of the positioning hole is larger than that of the second threaded hole.

[0010] As a preferred embodiment, the sliding table body includes a mounting seat and a fixing seat. A fixing seat is integrally provided at the left end and the right end of the mounting seat respectively. The structure and dimensions of the lower surface of the mounting seat match the structure and dimensions of the upper end of the sliding seat.

[0011] As a preferred embodiment, a first fixing hole is formed through the middle of the left end and the middle of the right end of the mounting seat respectively.

Obviously, the described embodiments are only some embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0024] Please refer to Figures 1 to 4 , the present invention provides a technical solution: a micro slide table electric cylinder with an easily replaceable slide table, including: an electric cylinder body 100, a slide table assembly 200. A plurality of slide table assemblies 200 are slidably installed inside the electric cylinder body 100, and a cylinder block 110 is provided at the front end of the electric cylinder body 100;

[0025] A cover 120 is fixed to the upper side of the cylinder block 110 by hexagon socket head cap screws. A slide rail 130 is installed on the left and right sides of the bottom of the cylinder block 110 respectively. A slider 140 is slidably installed on the upper side of each slide rail 130. A drive shaft 150 is rotatably installed inside the cylinder block 110.

[0026] The slide table assembly 200 includes a slide base 210 and a slide table body 220. The slide table body 220 is fixed to the upper side of the slide base 210. The left and right sides of the lower end of the slide base 210 are respectively fixedly connected to a slider 140.

[0027] Please refer to Figures 1 to 4 , a first threaded hole is respectively opened in the middle of the left side and the middle of the right side of the upper end of the slide base 210. A positioning hole is respectively opened downward on the left front side, the left rear side, the right front side, and the right rear side of the upper end of the slide base 210. The slide table assembly 200 is divided into the slide base 210 and the slide table body 220, which facilitates the subsequent replacement of the slide table body 220.

[0028] A connection hole 211 runs through the middle of the slide base 210 from front to back. A second threaded hole is respectively opened downward at the bottom of each positioning hole. The inner wall of the positioning hole is designed to be smooth, and the diameter of the positioning hole is larger than the diameter of the second threaded hole.

[0029] The slide table body 220 includes a mounting seat 222 and a fixing seat 221. A fixing seat 221 is integrally provided at the left end and the right end of the mounting seat 222 respectively. The structure and size of the lower surface of the mounting seat 222 match the structure and size of the upper end of the slide base 210.

[0030] A first fixing hole 223 runs through the middle of the left end and the middle of the right end of the mounting seat 222 downward respectively. The quantity, size, and distribution position of the first fixing holes 223 match the quantity, size, and distribution position of the first threaded holes.

[0031] As the first embodiment of the present invention, by dividing the slide table assembly 200 into two parts, namely the slide base 210 and the slide table body 220, the slide base 210 that is not easily damaged and does not need to be replaced is placed inside the cylinder block 110 and is slidably connected to the slide rail 130 through the slider 140. The slide table body 220 is fixed to the upper side of the slide base 210 by hexagon socket head cap screws. When replacement is needed, only the cover 120 needs to be opened to disassemble the slide table body 220, without disassembling the entire slide table assembly 200, and even less need to disassemble more components in the electric cylinder body 100. This greatly improves the disassembly and assembly efficiency of the slide table body 220 and reduces the difficulty of its later maintenance.

[0032] Please refer to Figure 4, on the left front side, left rear side of the left end of the mounting base 222, and on the right front side and right rear side of the right end, a second fixing hole 224 is formed by penetrating downward respectively. On the left front side, left rear side of the lower surface of the mounting base 222, and on the right front side and right rear side of the right end, a positioning post 225 is provided respectively. The number and distribution position of the positioning posts 225 are matched with the number and distribution position of the second fixing holes 224. The positioning posts 225 can position the installation of the slide body 220 and have the function of preventing deviation.

[0033] The lower end of each second fixing hole 224 extends downward through the positioning post 225. The axis of the positioning post 225 is collinear with the axis of the second fixing hole 224. The number, size and distribution position of the positioning posts 225 are matched with the number, size and distribution position of the positioning holes.

[0034] As the second embodiment of the present invention, based on the above first embodiment, in actual use, if it is necessary to install the replaced slide body 220 on the upper side of the slide base 210, the user aligns the four positioning posts 225 with the four positioning holes on the upper side of the slide base 210 respectively, and inserts the positioning posts 225 into the positioning holes (the first fixing hole 223 is convenient for fixing the slide base 210 and the slider 140). Then, the hexagon socket head cap screw can be inserted into the second fixing hole 224. Since a second threaded hole is opened downward at the bottom of each positioning hole, and an internal thread is provided on the inner wall of the bottom of each second threaded hole, the lower end of the hexagon socket head cap screw located in the second fixing hole 224 is threadedly connected with the second threaded hole, thereby firmly fixing the slide body 220 on the slide base 210. During the movement, the four positioning posts 225 can still play the role of limiting and preventing deviation, greatly improving the stability of the slide body 220 in use.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
