Description

Technical Field

[0001] The utility model relates to the technical field of transmission, in particular to a novel folding base for an electric cylinder device. Background Art

[0002] In the existing electric cylinder device with a reversible seat on the market, the position of the drive motor device is generally not adjustable after it is fixed on the reversible seat. Therefore, in the early assembly process, because the position of the drive motor is fixed, it will be relatively cumbersome to assemble the synchronous belt. Moreover, with long-term use, the synchronous belt may become loose. Because the position of the drive motor is fixed, it is generally necessary to replace the synchronous belt. When replacing the synchronous belt, some problems will also be faced during the assembly process.

[0003] In addition, the existing electric cylinder device generally has a ball screw with a flange structure and a piston with a push rod installed in the cylinder body. The push rod is installed at the front end of the piston, and then the piston is sleeved on the nut of the ball screw. The ball screw nut drives the piston to drive in the cylinder body of the electric cylinder.

[0004] However, the screw nuts of existing standard ball screws are generally designed with a raised flange structure, so there are strict requirements for their application scenarios. Because the existing ball screw nuts have a flange structure, when they are assembled into an electric cylinder or a slide, there are strict requirements for the space inside the electric cylinder. The internal space must be larger than the diameter of the flange, otherwise the screw with the flange will not be able to be assembled into the electric cylinder.

[0005] However, in some application scenarios of electric cylinders, there are strict requirements on the size of the electric cylinder. If the size of the electric cylinder is reduced, the ball screw and its nut structure inside it also need to be reduced. After the reduction, the pressure that the ball screw and nut structure can withstand will also be reduced accordingly. Therefore, it will not be able to meet the production requirements.

[0006] Moreover, when the lead screw composed of a nut with a flange structure is used, it needs to be matched with a piston adapter push rod. Therefore, when it is produced and processed, more parts are required and the assembly process is also more complicated. Utility Model Content

[0007] The technical problem solved by the utility model is to provide a novel folding base which is convenient for assembling and maintaining an electric cylinder.

[0008] The technical solution adopted by the utility model to solve its technical problems is:

[0009] A new type of folding base for an electric cylinder device comprises an upper base and a lower cover plate, wherein the upper base and the lower cover plate are fixed together by a plurality of bolts; the upper end of the upper base is divided into two parts, one end is a cylinder body mounting seat for mounting a cylinder body, and the other end is a motor mounting seat for mounting a motor, cylinder body fixing holes are arranged at the four corners of the cylinder body mounting seat, and a first through hole is opened in the middle for the screw rod to extend therethrough, motor limiting holes are arranged at the four corners of the motor mounting seat, and a second through hole is opened in the middle for the motor shaft to extend therethrough, and the motor limiting holes are strip-shaped and are arranged in parallel along the arrangement direction of the cylinder body and the motor.

[0010] Furthermore, the four sides of the cylinder mounting seat are regularly provided with positioning openings for facilitating the positioning and assembly of the cylinder.

[0011] Further, the positioning port is arranged at a middle position between the front and rear sides or the left and right sides of the cylinder mounting seat, or at a middle position between the front and rear sides and the left side of the cylinder mounting seat.

[0012] Furthermore, the inner bottom surface of the lower cover plate is also regularly provided with synchronous pulley limiting grooves.

[0015] Furthermore, a single fixing stud and a single fixing column thereunder form a group and are respectively arranged at four walls and a middle position inside the upper base and the lower cover plate.

[0028] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation methods of the utility model are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific embodiments disclosed below.

[0029] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art in the technical field of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The term "and / or" used herein includes any and all combinations of one or more related listed items.

[0030] like Figure 1 As shown, the utility model provides a novel folding base for an electric cylinder device, comprising an upper base 1 and a lower cover plate 2. The upper base 1 and the lower cover plate 2 are locked and fixed together by a plurality of bolts 3 to form the novel folding base of the utility model.

[0031] The upper end of the upper base 1 is divided into two parts, one end is a cylinder mounting seat 11, and the other end is a motor mounting seat 12. Figure 1 As shown, the cylinder mounting seat 11 is arranged on the left side of the upper base 1, and the motor mounting seat 12 is arranged on the right side of the upper base 1. Cylinder fixing holes 1103 are arranged at the four corners of the cylinder mounting seat 11, and a first through hole 1101 is opened in the middle thereof. Motor limiting holes 1202 are also arranged at the four corners of the motor mounting seat 12, and a second through hole 1201 is opened in the middle thereof.

[0032] Among them, Figure 1 and Figure 3 As shown, the first through hole 1101 is used for the lead screw in the cylinder body to pass through to install the synchronous pulley 6, and the second through hole 1201 is used for the rotating shaft at the front end of the motor to pass through to install another synchronous pulley. The synchronous pulley on the lead screw and the synchronous pulley 6 on the motor shaft are connected for transmission through a synchronous belt 7.

[0033] Furthermore, the cylinder fixing hole 1103 is a circular through hole, and the motor limiting hole 1202 is a strip-shaped limiting hole. Figure 3As shown, the cylinder body 4 is arranged and installed on the cylinder body mounting seat 11, and the four corners are bolted from the lower end of the upper base 1 through the cylinder body fixing hole 1103 and matched with the threaded hole at the bottom end of the cylinder body 4, so that the cylinder body 4 is locked and fixed on the left side of the upper base. The motor 10 is arranged and installed on the motor mounting seat 12 on the right side of the upper base, and the four corners are also bolted from the upper end of the motor base through the motor base and the motor limit hole 1202 in sequence to the lower end of the upper base 1, and then the motor is locked and fixed on the right side of the upper base through nuts.

[0034] Further, the strip-shaped motor limiting hole 1202 is horizontally arranged along the arrangement direction of the cylinder body and the motor. Through the strip-shaped limiting hole, the distance between the motor and the cylinder body can be easily adjusted, thereby facilitating the early assembly of the synchronous belt and the maintenance or replacement of the synchronous belt in the later stage.

[0035] like Figure 3 As shown, the lower end of the cylinder body 4 is a rear end cover 41, and a limit bolt can be arranged between the rear end cover 41 and the motor 5. The limit bolt is fixed in the threaded hole of the rear end cover, and its top end contacts the motor. Thus, the distance between the motor and the rear end cover, that is, the distance between the motor and the cylinder body can be adjusted by adjusting the limit bolt. In other words, by adjusting the limit bolt, the distance between the synchronous pulley on the motor shaft and the synchronous pulley 6 at the rear end of the ball screw can be quickly adjusted to quickly adjust the tightness of the synchronous belt 7 on the synchronous pulley. This can facilitate the assembly of the synchronous belt in the early stage, as well as the maintenance and replacement of the synchronous belt in the later stage.

[0036] like Figure 1 As shown, in order to facilitate the installation of the cylinder body on the cylinder body mounting seat 11, the four sides of the cylinder body mounting seat are regularly provided with positioning holes 1102. During use, the rear end cover 41 can be redesigned, and a protruding positioning block is provided at the corresponding position of the rear end cover 41. Therefore, the cylinder body 4 can be quickly assembled to the cylinder body mounting seat 11 by quickly inserting the protruding positioning block into the positioning holes 1102 on the four sides of the cylinder body mounting seat.

[0037] Preferably, the positioning opening 1102 can be arranged at the middle position of the front and rear sides or the left and right sides of the cylinder mounting base 11, or as Figure 1 As shown in , it is arranged at the middle position of the front and rear sides and the left side of the cylinder body mounting seat 11.

[0038] like Figure 2 As shown, the interior of the lower cover plate 2 is also regularly provided with synchronous belt pulley limiting grooves 22. When the stroke is too long, in order to avoid the shaking of the synchronous belt pulley, a ball bearing can be further arranged and installed in the synchronous belt pulley limiting groove. The tail of the screw rod and the motor shaft pass through the synchronous belt pulley and are inserted into the ball bearing in the synchronous belt pulley limiting groove, thereby improving stability and avoiding the shaking of the synchronous belt pulley.

[0039] like Figure 1 and Figure 2 As shown, the bolt 3 passes through the bottom of the lower cover plate 2 to lock and install it with the upper base. Therefore, a plurality of fixing studs 13 are regularly arranged inside the upper base 1, and a threaded hole is arranged at the lower end of the fixing stud 13 to match the bolt 3. A plurality of fixing columns 21 are regularly arranged inside the lower cover plate 2 at the corresponding position, and through holes are arranged above and below the fixing columns 21 to facilitate the insertion of the bolts 3, and the through holes penetrate to the lower end of the lower cover plate 2.

[0040] Furthermore, a plurality of fixing studs 13 and a plurality of fixing columns 21 inside the upper base 1 and the lower cover plate 2 are respectively arranged on the four walls and the middle position inside the upper base 1 and the lower cover plate 2. Figure 1 As shown, a group of fixing columns and fixing studs are respectively arranged at the middle positions of the left and right inner walls, a group of fixing columns and fixing studs are respectively arranged at about one-third and two-thirds of the front and rear inner walls, and a group of fixing columns and fixing studs are arranged at the middle position of the interior. Therefore, for the cylinder mounting seat 11 and the motor mounting seat 12 of the upper base, the middle positions of the four sides of the cylinder mounting seat 11 and the motor mounting seat 12 include fixing columns and fixing studs.

[0041] The specific embodiments described above further illustrate the purpose, technical solutions and beneficial effects of the present invention. It should be understood that the above description is only a specific embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
