Description

Technical Field

[0001] This utility model relates to the field of motor stator transfer tooling technology, and in particular to an auxiliary device for clamping and transferring the inner and outer circles of a motor stator. Background Technology

[0002] After the motor stator or segmented gear stator is wound, because the entire stator is circular, there is no space or structure for hoisting and transferring it. This means that the stator must be manually moved each time, which is very strenuous and inconvenient, and also poses safety hazards. It is easy for it to fall and injure people, damage products, seriously affect production progress, increase production costs, and cause workplace injuries. To address these problems, this utility model provides an auxiliary device for clamping and transferring the inner and outer circles of the motor stator. Summary of the Invention

[0003] The purpose of this invention is to provide an auxiliary device for clamping and transferring the inner and outer circles of a motor stator.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution: An auxiliary device for clamping and transferring the inner and outer circles of a motor stator includes a pull rod, an outer lever arm, an inner lever arm, an inner clamping rod, an outer clamping rod, an outer clamping block, and an inner clamping block. The number of inner and outer clamping rods is multiple and equal. Each inner clamping rod is hinged to one end of two vertically parallel inner lever arms, and the other end of the two inner lever arms is hinged to the pull rod. The outer side of the bottom end of each inner clamping rod is fixedly connected to an inner clamping block. Each outer clamping rod is hinged to one end of two vertically parallel outer lever arms, and the other end of the outer lever arm is hinged to the pull rod. The inner side of the bottom end of each outer clamping rod is fixedly connected to an outer clamping block. The outer clamping block is located outside the inner clamping block. The two sides are arranged in pairs to form a clamping structure. The side wall of the pull rod is also provided with the same number of guide arms as the number of outer clamping rods. Each guide arm is provided with a guide groove for the corresponding inner clamping rod and outer clamping rod to pass through. The side of the inner clamping rod and outer clamping rod in contact with the guide arm is provided with a longitudinal groove. The side of the guide arm is provided with a transverse groove that intersects with the longitudinal groove. A guide bearing rod is installed at the intersection of the transverse groove and the longitudinal groove. The guide bearing rod can be moved laterally along the transverse groove and longitudinally along the longitudinal groove. Specifically, the guide bearing rod consists of a guide rod and bearings installed at both ends of the guide rod. The bearings are locked inside the transverse grooves on both sides of the guide groove.

[0005] Furthermore, both the outer and inner clamping blocks are arc-shaped structures, and the curvature of their arc structures is adapted to the curvature of the motor stator to be clamped, thereby increasing the contact area during clamping and fitting the inner and outer sides of the motor stator.

[0006] Furthermore, there are four inner clamping rods and four outer clamping rods, and four outer clamping blocks and four inner clamping blocks. The specific number can be designed according to the diameter of the motor stator. Generally, the larger the diameter, the more blocks are needed to ensure the distribution of clamping force.

[0007] Furthermore, the top of the pull rod is provided with a pull ring, which facilitates the connection between the crane and the pull rod to lift the tooling body.

[0008] In summary, this utility model has the following beneficial effects: This utility model adopts the directional and calibrating transmission force of the guide bearing rod, and uses a crane or upward force to lift the fixture. The arc structure of the fixture automatically clamps the workpiece through the transmission of the lever arm. The greater the weight of the workpiece, the greater the clamping force, and the more firmly and reliably the workpiece is clamped, which improves work efficiency and product qualification rate, and reduces safety risks in the work process.

[0010] The present invention will be further described in detail below with reference to the accompanying drawings. The technical solutions in the embodiments of the present invention will be clearly and completely described. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present invention.

[0011] like Figure 2-4As shown, an auxiliary device for clamping and transferring the inner and outer circles of a motor stator includes a pull rod 3, an outer force arm 4, an inner force arm 5, an inner clamping rod 6, an outer clamping rod 7, an outer clamping block 9, and an inner clamping block 10. There are multiple inner clamping rods 6 and 7, and the number of both is equal. Each inner clamping rod 6 is hinged to one end of two vertically parallel inner force arms 5, and the other end of the two inner force arms 5 is hinged to the pull rod 3. The outer side of the bottom end of each inner clamping rod 6 is fixedly connected to an inner clamping block 10. Each outer clamping rod 7 is hinged to one end of two vertically parallel outer force arms 4, and the other end of the outer force arms 5 is hinged to the pull rod 3. The inner side of the bottom end of each outer clamping rod 7 is fixedly connected to an outer clamping block 9. The outer clamping blocks 9 are located outside the inner clamping blocks 10, two to three times a day. The components are grouped to form a clamping structure. The side wall of the pull rod 3 is also provided with the same number of guide arms 8 as the outer clamping rod 7. Each guide arm 8 is provided with a guide groove 11 through which the corresponding inner clamping rod 6 and outer clamping rod 7 pass. The side of the inner clamping rod 6 and outer clamping rod 7 in contact with the guide arm 8 is provided with a longitudinal groove 13. The side of the guide arm 8 is provided with a transverse groove 12 that intersects with the longitudinal groove 13. A guide bearing rod 14 is installed at the intersection of the transverse groove 12 and the longitudinal groove 13. The guide bearing rod 14 can be moved laterally along the transverse groove 12 and longitudinally along the longitudinal groove 13. Specifically, the guide bearing rod 14 consists of a guide rod and bearings installed at both ends of the guide rod. The bearings are fitted inside the transverse grooves 12 on both sides of the guide groove 11.

[0012] Furthermore, such as Figure 3 As shown, both the outer clamping block 9 and the inner clamping block 10 are arc-shaped structures, and the curvature of their arc structures is adapted to the curvature of the motor stator 2 to be clamped, thereby increasing the contact area during clamping and fitting the inner and outer sides of the motor stator 2.

[0013] Furthermore, there are four inner clamping rods 6 and four outer clamping rods 7, and four outer clamping blocks 9 and four inner clamping blocks 10. The specific number can be designed according to the diameter of the motor stator. Generally, the larger the diameter, the more blocks are needed to ensure the distribution of clamping force.

[0014] Furthermore, the top of the pull rod 3 is provided with a pull ring, which facilitates the connection between the crane and the pull rod 3 to lift the tooling body 1.

[0015] Working principle: such as Figure 1 and Figure 5 As shown, the tooling equipment is moved to the workpiece area by a crane, initially aligning the tooling with the center of the workpiece. Then, the crane quickly descends to the highest point of the workpiece, and then slowly descends to fit over the inner and outer circumference of the workpiece. After initial fitting, the crane slowly rises, allowing the tooling to automatically clamp onto the workpiece due to its own weight. Once clamped, the workpiece is lifted and moved to the designated placement position. This completes the entire motor stator transfer process.

[0016] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
