Description

Technical Field

[0001] This utility model relates to the field of electric cylinder technology, and in particular to an electric cylinder module with a maintenance window. Background Technology

[0002] Servo electric cylinders are modular products that integrate servo motors and ball screws. They convert the rotary motion of the servo motor into linear motion, while optimizing the servo motor for precise rotational speed control, precise torque control, and precise rotational speed control. Therefore, they are widely used in material handling, high-precision machining and manufacturing, aerospace testing equipment, six-degree-of-freedom simulators, robots, injection molding machines, mold control, valve control, precision machine tools, and automotive manufacturing equipment.

[0003] To prevent dust from affecting the components in the electric cylinder, some manufacturers use enclosed electric cylinders in certain environments.

[0004] Couplings used in enclosed electric cylinders are prone to various problems that affect the driving effect of the electric cylinder as the usage time increases. Therefore, regular maintenance of the coupling is required. However, the coupling is located inside the protective housing of the enclosed electric cylinder, which means that the operator has to disassemble the housing to maintain the coupling, which is too cumbersome and affects the maintenance efficiency. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] To address the aforementioned problems, this utility model provides the following technical solution:

[0007] An electric cylinder module with a maintenance window includes an electric cylinder body and a first protective shell fastened to one end of the electric cylinder body having an output shaft. A coupling is connected to the output shaft of the electric cylinder body, and the first protective shell is sleeved on the coupling. Both ends of the coupling are provided with a cut-out, and a pressing component for driving the cut-out to close. One side of the first protective shell is provided with a window that can be opened and closed corresponding to the coupling. When maintenance is required, opening and closing the window allows the pressing component to drive the cut-out to close / open, so as to facilitate the maintenance of the coupling.

[0008] Based on the above technical solution, the present invention can be further improved as follows.

[0009] As a preferred embodiment of the electric cylinder module with an inspection window of this utility model, the cut-off is set on the X-axis and the extrusion component is set on the Y-axis.

[0010] As a preferred embodiment of the electric cylinder module with an inspection window of this utility model, the extrusion assembly includes a threaded port that passes through the coupling and a screw threadedly connected to the threaded port, with the threaded port passing through the cut end.

Detailed Implementation

[0021] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0023] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0024] Example 1

[0025] Reference Figures 1 to 3 This is an embodiment of the present invention, which provides an electric cylinder module with an inspection window, such as... Figure 1 As shown, the device includes an electric cylinder body 100 and a first protective shell 200 fastened to one end of the electric cylinder body 100 having an output shaft. A coupling 300 is connected to the output shaft of the electric cylinder body 100, and the first protective shell 200 is sleeved on the coupling 300. The device is characterized in that: both ends of the coupling 300 are provided with a cut-out 301, and a pressing component 302 for driving the cut-out 301 to close. One side of the first protective shell 200 is provided with a window 201 that can be opened and closed corresponding to the coupling 300. When maintenance is required, opening and closing the window 201 allows the pressing component 302 to be driven to close / open the cut-out 301, so as to facilitate the maintenance of the coupling 300.

[0026] Specifically, the window 201 on the first protective housing 200 allows operators to directly perform maintenance (such as adding lubricating oil or tightening bolts) on the coupling 300 housed inside the first protective housing 200 through the window 201. This facilitates daily maintenance of the coupling 300. At the same time, the window 201 can be opened and closed. Closing the window 201 can prevent dust from entering the first protective housing 200 and then the coupling 300 during daily use, thus preventing increased wear on the coupling 300 during daily use.

[0027] The cut-off point 301 is positioned on the X-axis, and the extrusion assembly 302 is positioned on the Y-axis. For example... Figure 2 The X-axis shown can be considered as the horizontal axis and the Y-axis can be considered as the vertical axis. This allows the cut 301 on the coupling 300 to close under the pressure of the extrusion assembly 302 when the extrusion assembly 302 is running, thereby strengthening the tightness of the connection between the coupling 300 and the rod inserted therein.

[0028] The extrusion assembly 302 includes a threaded opening 302-1 that passes through the coupling 300 and a screw 302-2 that is threaded into the threaded opening 302-1. The threaded opening 302-1 passes through the cut-off end 301. When the screw 302-2 is twisted, because the screw 302-2 has a screw head that is larger than the threaded opening 302-1, when one end of the screw head extrudes the coupling 300, the cut-off end 301 on the coupling 300 begins to close. The threaded connection between the threaded opening 302-1 and the screw 302-2 ensures the stability of the cut-off end 301 after it closes.

[0029] The window 201 includes a placement platform 201-1 formed on the outer surface of the first protective shell 200, and a detachable plate 201-2 disposed on the placement platform 201-1. The portion of the plate 201-2 that overlaps with the placement platform 201-1 may have a locking opening, and a screw may be threaded into the locking opening, so that the opening and closing of the window 201 can be achieved by separating and inserting the plate 201-2 from the placement platform 201-1, and the screw can enhance the stability of the plate 201-2 after it is placed into the placement platform 201-1.

[0030] The first protective shell 200 includes a first cavity 202, a second cavity 203, and a third cavity 204 that are integrally formed and connected in sequence, with a coupling 300 disposed in the first cavity 202. The diameter of the second cavity 203 is smaller than that of the first cavity 202, and the diameter of the first cavity 202 is smaller than that of the third cavity 204, so as to accommodate parts of different sizes.

[0031] The second cavity 203 is cylindrical and has a first end 203-1 and a second end 203-2 that are respectively inserted into the first cavity 202 and the third cavity 204. The second cavity 202 extends into the first cavity 202 and the third cavity 204 through the first end 203-1 and the second end 203-2, allowing it to function as a screw nut retainer. Because the second cavity 203 is integrally formed within the first protective shell 200, it has higher strength and greater stability compared to a detachable screw nut retainer.

[0032] A snap-fit ​​cavity 205 is provided between the outer wall of the second end 203-2 and the inner wall of the third cavity 204, and a positioning cylinder 206 is inserted into the snap-fit ​​cavity 205. The positioning cylinder 206 can protect the components located in the third cavity 204.

[0033] It is important to note that the constructions and arrangements of this application shown in several different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, those who consult this disclosure will readily understand that many modifications are possible (e.g., changes in the size, dimensions, structure, shape and proportion of various elements, as well as parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, color, orientation, etc.) without substantially departing from the novel teachings and advantages of the subject matter described in this application). For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of elements may be inverted or otherwise altered, and the nature or number or position of discrete elements may be changed or altered. Therefore, all such modifications are intended to be included within the scope of this utility model.

In the claims, any "device plus function" clause is intended to cover the structure described herein that performs the function, and not only structural equivalents but also equivalent structures. Without departing from the scope of this invention, other substitutions, modifications, alterations, and omissions may be made in the design, operation, and arrangement of the exemplary embodiments. Therefore, this invention is not limited to the specific embodiments, but extends to various modifications that still fall within the scope of the appended claims.
