[0003] The purpose of this utility model is to provide an electric drawing device to solve the problems mentioned in the background art. Currently, the drawing devices on the market are mainly divided into two categories: manual drawing devices and simple electric drawing equipment. Most small drawing devices rely on manual operation and apply pulling force through structures such as rocker arms and lead screws. Some mechanical drawing equipment is inconvenient to position the workpiece, making operation inconvenient and reducing work efficiency.

[0004] To achieve the above objectives, this utility model provides the following technical solution: an electric pulling device, including a fixed base, a servo cylinder at the bottom of the fixed base, a linear guide rail on the back of the fixed base, a fixture clamping cylinder fixedly installed at the middle of both sides of the fixed base, a movable base fixedly connected to the output end of the fixture clamping cylinder, an upper protective clamping plate at the bottom of the movable base, a pulling fixture fixedly installed on one side of the upper protective clamping plate, a movable cylinder connected to the output end of the servo cylinder, a lifting angle frame at the top of the movable cylinder, an end piece on one side of the lifting angle frame, protective sleeve clamping cylinders installed on both sides of the lifting angle frame, a lower protective clamping plate connected to the output end of the protective sleeve clamping cylinder, and a guide positioning fixture at the top of the end piece.

[0005] As a preferred technical solution of this utility model, a sliding sleeve matching the linear guide rail is fixedly installed on the back of the fixed base. The sliding sleeve is slidably connected to the linear guide rail, which facilitates the connection between the fixed base and the linear guide rail.

[0006] As a preferred technical solution of this utility model, the bottom of the servo electric cylinder is fixedly connected to a base, and one corner of the servo electric cylinder is fixedly connected to a mounting base, which facilitates the installation and fixation of the servo electric cylinder.

[0007] As a preferred technical solution of this utility model, a fixing frame is fixedly connected to the bottom of one side of the servo electric cylinder, and a threaded hole is opened on the top of the fixing frame for easy installation and fixing.

[0008] As a preferred technical solution of this utility model, the upper protective clamp plate corresponds to the lower protective clamp plate, the pulling fixture corresponds to the guide positioning fixture, and the fixing seat is provided with fixing holes on both sides.

[0009] Compared with the prior art, the beneficial effects of this utility model are:

[0010] The workpiece is inserted into the guide positioning fixture. The workpiece is held steady with one hand, while the fixture clamping cylinder and the protective sleeve clamping cylinder are activated. The fixture clamping cylinder pushes the moving seat and the upper protective clamping plate towards the center. The pulling fixture on the upper protective clamping plate clamps the workpiece from above. The protective sleeve clamping cylinder pushes the lower protective clamping plate to clamp and position the workpiece. During the pulling test, the moving cylinder moves up and down through the servo electric cylinder. The moving cylinder causes the lifting angle frame and end plate to move, thereby indirectly pulling the lower protective clamping plate and pulling the workpiece for the pulling test. The entire electric pulling device has good workpiece positioning effect, is easy to operate, and improves work efficiency. Attached Figure Description

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1-3This utility model provides an electric pulling device, including a fixed base 1, a servo cylinder 10 at the bottom of the fixed base 1, a linear guide rail 2 on the back of the fixed base 1, a jig clamping cylinder 3 fixedly installed in the middle of both sides of the fixed base 1, a movable base 4 fixedly connected to the output end of the jig clamping cylinder 3, an upper protective clamping plate 5 at the bottom of the movable base 4, a pulling jig 9 fixedly installed on one side of the upper protective clamping plate 5, a movable cylinder 12 connected to the output end of the servo cylinder 10, a lifting angle bracket 13 at the top of the movable cylinder 12, an end piece 14 on one side of the lifting angle bracket 13, protective sleeve clamping cylinders 7 installed on both sides of the lifting angle bracket 13, a lower protective clamping plate 8 connected to the output end of the protective sleeve clamping cylinder 7, and a guide positioning jig 18 at the top of the end piece 14.

[0017] See Figure 1-3 A sliding sleeve 17 matching the linear guide rail 2 is fixedly installed on the back of the fixed base 1. The sliding sleeve 17 is slidably connected to the linear guide rail 2. A base 15 is fixedly connected to the bottom of the servo electric cylinder 10. A mounting base 11 is fixedly connected to one corner of the servo electric cylinder 10.

[0018] In this embodiment, the workpiece is manually placed on the front of the fixed seat 1, placed vertically, and clamped into the guide positioning fixture 18. The workpiece is held steady with one hand. The fixture clamping cylinder 3 and the protective sleeve clamping cylinder 7 are activated. The fixture clamping cylinder 3 pushes the moving seat 4 and the upper protective clamping plate 5 towards the center. The pull-out fixture 9 on the upper protective clamping plate 5 clamps the workpiece from above. The protective sleeve clamping cylinder 7 pushes the lower protective clamping plate 8 to clamp and position the workpiece.

[0019] See Figure 1-3 A fixed bracket 16 is fixedly connected to the bottom of one side of the servo electric cylinder 10. The top of the fixed bracket 16 is provided with a threaded hole. The upper protective clamp 5 corresponds to the lower protective clamp 8. The pulling fixture 9 corresponds to the guide positioning fixture 18. Fixed holes 6 are provided on both sides of the fixed seat 1.

[0020] In this embodiment, during the pull-out test, the servo electric cylinder 10 moves the moving cylinder 12 up and down, and the moving cylinder 12 causes the lifting angle frame 13 and the end piece 14 to move, thereby indirectly pulling the lower protective clamping plate 8 to move, thereby pulling the workpiece for pull-out test. After the pull-out test, the servo electric cylinder 10 descends, and all clamping cylinders retract back to their original positions.

[0021] In practical use, the electric pulling device of this utility model involves manually placing the workpiece on the front of the fixed seat 1, positioning it vertically, and clamping it onto the guide positioning fixture 18. The workpiece is held steady with one hand. Simultaneously, the fixture clamping cylinder 3 and the protective sleeve clamping cylinder 7 are activated. The fixture clamping cylinder 3 pushes the moving seat 4 and the upper protective clamping plate 5 towards the center. The pulling fixture 9 on the upper protective clamping plate 5 clamps the workpiece from above. The protective sleeve clamping cylinder 7 pushes the lower protective clamping plate 8 to clamp and position the workpiece. During the pulling test, the servo electric cylinder 10 moves the moving cylinder 12 up and down. The moving cylinder 12 causes the lifting angle frame 13 and the end plate 14 to move, indirectly pulling the lower protective clamping plate 8, thus pulling the workpiece for the pulling test. After the pulling test, the servo electric cylinder 10 descends, and all clamping cylinders retract to their original positions. The entire electric pulling device provides good workpiece positioning, is easy to operate, and improves work efficiency.

[0022] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
