Description

Technical Field

[0001] This utility model relates to the technical field of electric motor manufacturing equipment, specifically an electric motor manufacturing assembly machine. Background Technology

[0002] In the manufacturing process of electric motors, assembly fixtures are indispensable auxiliary tools. Existing assembly fixtures, such as the utility model patent with patent number 202222470740.4, provide an adjustable electric motor assembly fixture. This fixture, through structures such as a suspension plate, a U-shaped mounting bracket, a clamping plate, and a movable plate, enables the adjustment of the angle and height of the motor casing during assembly, providing convenience for assembly personnel. However, this device mainly focuses on fixing the casing and adjusting the angle, and still has limitations in assembling internal components of the electric motor, especially in terms of compatibility with different specifications of electric motors.

[0003] Furthermore, traditional assembly fixtures typically rely on rigid clamping structures when fixing electric motors. This type of structure can easily damage the motor housing during the fixing process, especially for high-precision motor components. Rigid clamping can cause housing deformation, thereby affecting the assembly accuracy and performance of the motor.

[0004] In summary, existing electric motor assembly fixtures are inadequate in terms of adapting to electric motors of different specifications and protecting the motor housing, and there is an urgent need for an assembly machine that can effectively solve these problems. Utility Model Content

[0005] (a) Technical problems to be solved

[0006] In view of the shortcomings of the prior art, this utility model provides an electric motor manufacturing and assembly machine, which solves the problems mentioned in the background art.

[0007] (II) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: an electric motor manufacturing assembly machine, comprising a third base, a support base, and a fixing component. The support base is fixedly installed on the upper center of the third base, and an arc-shaped groove for placing the main body of the electric motor is provided on the upper part of the support base. The fixing component includes two clamping assemblies, both of which are installed on the third base and are located on opposite sides of the support base. Each clamping assembly includes a second support plate, a second movable rod, a first movable rod, and an arc-shaped plate. The lower end of the second support plate is fixedly connected to the third base. The second movable rod is C-shaped, with its middle part hinged to the second support plate, and its upper end fixedly connected to the arc-shaped plate. A sliding groove is provided at the lower end of the second movable rod, and the lower end of the first movable rod is slidably connected to the second movable rod through the sliding groove. The upper end of the first movable rod obliquely penetrates the support base and is slidably connected to it, with the upper end of the first movable rod located within the arc-shaped groove of the support base.

[0009] Optionally, the clamping assembly further includes an electric telescopic rod and a wedge block. The electric telescopic rod is fixedly installed on one side wall of the support base, and the wedge block is fixedly installed on the output shaft end of the electric telescopic rod. A limit hole is opened in the middle of the first movable rod, and the electric telescopic rod drives the wedge block to insert into or pull out of the limit hole of the first movable rod.

[0010] Optionally, the support base has two grooves in its arc-shaped groove; the upper end of the first movable rod is T-shaped and passes through the groove of the support base.

[0011] Optionally, it also includes a first base and a second base. Multiple servo electric cylinders are fixedly installed on the first base, and the second base is fixedly installed on the output shaft end of each servo electric cylinder. Each servo electric cylinder synchronously pushes the second base to move up and down.

[0012] Optionally, two hinge seats are fixedly connected to the second base, and the third base is hingedly mounted on the two hinge seats. A motor is fixedly mounted on the second base, and the motor is connected to the third base for transmission. The motor drives the third base to rotate partially.

[0013] (III) Beneficial Effects

[0014] This utility model provides an electric motor manufacturing and assembly machine, which has the following beneficial effects:

[0015] 1. This electric motor manufacturing assembly machine, through its unique clamping component design, enables rapid adaptation to electric motors of different specifications. The first and second movable rods in the clamping component work together to form a flexible clamping mechanism. When placing electric motors of different sizes, the first movable rod slides along the arc-shaped groove of the support base under the weight of the motor, causing the second movable rod to rotate around the hinge point. During this process, the arc-shaped plate moves accordingly, achieving adaptive clamping of the motor housing. Simultaneously, the arc-shaped groove and recess design of the support base provides sufficient space for the movement of the first movable rod, ensuring smooth and unobstructed clamping action. This adaptive clamping function allows the assembly machine to quickly switch between assembling different models of electric motors without changing fixtures or making complex adjustments, greatly improving production efficiency and reducing production costs, making it particularly suitable for multi-variety, small-batch electric motor production scenarios.

[0016] 2. This utility model employs a flexible clamping method in its clamping assembly, avoiding the risk of damage to the motor housing caused by traditional rigid clamping. A torsion spring is installed at the connection between the second movable rod and the arc-shaped plate. During clamping, the elastic deformation of the torsion spring absorbs part of the clamping force, providing a buffering effect. When the electric telescopic rod drives the wedge block to insert into the limiting hole, the first movable rod continues to move, causing a slight deformation of the arc-shaped plate through the linkage mechanism, tightly fitting the surface of the motor housing. This flexible clamping not only ensures the stability of the motor during assembly but also effectively prevents deformation of the housing due to uneven force, ensuring the assembly accuracy of the motor. Simultaneously, the curved surface design of the arc-shaped plate increases the contact area with the motor housing, further reducing the pressure per unit area and minimizing the possibility of damage caused by excessive localized force, providing a reliable guarantee for the assembly of high-precision motors.

[0023] Please see Figures 1 to 4 The present invention provides a technical solution: the electric motor manufacturing assembly machine shown in the present invention is used to assist in the assembly of components in the main body of the electric motor.

[0024] The electric motor manufacturing and assembly machine includes a third base 6, a support base 7, and a fixing component. The support base 7 is fixedly installed in the upper middle part of the third base 6, and the upper part of the support base 7 has an arc-shaped groove for placing the main body of the electric motor.

[0025] The fixing component includes two clamping assemblies, both of which are mounted on the third base 6 and are located on both sides of the support base 7.

[0026] The clamping assembly includes a second support plate 11, a second movable rod 10, a first movable rod 8, and an arc-shaped plate 12. The lower end of the second support plate 11 is fixedly connected to the third base 6. The second movable rod 10 is C-shaped, with its middle section hinged to the second support plate 11 and its upper end fixedly connected to the arc-shaped plate 12. A sliding groove is provided at the lower end of the second movable rod 10, and the lower end of the first movable rod 8 is slidably connected to the second movable rod 10 through the sliding groove. The upper end of the first movable rod 8 obliquely penetrates the support base 7 and the two are slidably connected. The upper end of the first movable rod 8 is located in the arc-shaped groove of the support base 7.

[0027] The second movable rod 10 is C-shaped, and its middle part is hinged to the second support plate 11. This hinge structure allows the second movable rod 10 to rotate around the hinge point at a certain angle. The shape of the arc plate 12 is adapted to the curved surface of the motor housing, providing uniform clamping force. The sliding connection between the first movable rod 8 and the second movable rod 10 allows the first movable rod 8 to move flexibly along the sliding groove of the second movable rod 10. A torsion spring is also provided at the hinge point between the second movable rod 10 and the second support plate 11. When assembling the motor, the motor is first placed in the arc groove of the support base 7. At this time, the bottom of the motor contacts the support base 7, and the side wall of the motor contacts the upper end of the first movable rod 8. Under the action of the motor's own weight, the upper end of the first movable rod 8 is pushed downward. As the first movable rod 8 moves, its lower end drives the second movable rod 10 to rotate around the hinge point with the second support plate 11. When the second movable rod 10 rotates, the arc-shaped plate 12 swings toward the motor and begins to clamp the motor housing. At this time, the torsion spring (installed at the hinge between the second movable rod 10 and the second support plate 11) deforms, stores elastic potential energy, and plays a buffering role to prevent excessive clamping force from damaging the motor housing.

[0028] Specifically, the clamping assembly also includes an electric telescopic rod 13 and a wedge block 9. The electric telescopic rod 13 is fixedly installed on one side wall of the support base 7, and the wedge block 9 is fixedly installed on the output shaft end of the electric telescopic rod 13. A limit hole 14 is opened in the middle of the first movable rod 8, and the electric telescopic rod 13 drives the wedge block 9 to insert into or pull out of the limit hole 14 of the first movable rod 8.

[0029] When the first movable rod 8 moves to the alignment of its limiting hole 14 with the wedge block 9 of the electric telescopic rod 13, the electric telescopic rod 13 is activated, driving the wedge block 9 to insert into the limiting hole 14. During insertion, the wedge-shaped surface of the wedge block 9 gradually rises, pushing the first movable rod 8 further into the groove 15. During this process, the arc-shaped plate 12 further presses against the motor housing, achieving precise clamping. Once the wedge block 9 is fully inserted into the limiting hole 14, the position of the first movable rod 8 is locked, ensuring a stable clamping force of the arc-shaped plate 12 on the motor housing. At this point, the motor is securely fixed to the support base 7, providing a stable platform for subsequent component assembly.

[0030] Specifically, two grooves 15 are formed in the arc-shaped groove of the support base 7. The upper end of the first movable rod 8 is T-shaped and passes through the groove 15 of the support base 7.

[0031] The T-shaped end of the first movable rod 8 can fit perfectly into the groove 15. This structural design allows the first movable rod 8 to have a certain degree of freedom of movement within the arc-shaped groove of the support 7, providing a basis for the self-adaptation of the clamping assembly.

[0032] Specifically, the electric motor manufacturing assembly machine also includes a first base 1 and a second base 3. Multiple servo electric cylinders 2 are fixedly mounted on the first base 1, and the second base 3 is fixedly mounted on the output shaft end of each servo electric cylinder 2. Each servo electric cylinder 2 synchronously pushes the second base 3 to move up and down. Two hinge seats 4 are fixedly connected to the second base 3, and a third base 6 is hingedly mounted on the two hinge seats 4. A motor 5 is fixedly mounted on the second base 3, and the motor 5 is connected to the third base 6 via a transmission connection, driving the third base 6 to rotate partially.

[0033] The first base 1 serves as the fundamental support structure for the entire assembly machine. The lifting height of the second base 3 can be precisely controlled through the synchronized extension and retraction of multiple servo electric cylinders 2. This height adjustment function allows the assembly machine to adapt to motors of different sizes and production tasks with varying assembly height requirements. The motor 5 is connected to the third base 6 via a transmission mechanism (such as gears or connecting rods). Starting the motor 5 drives the third base 6 to rotate partially, thereby causing the support base 7 and clamping components mounted on it to rotate synchronously. This rotation function facilitates multi-angle assembly of the motor, allowing assembly personnel to complete component assembly work in various directions without frequently adjusting the motor's position, significantly improving assembly efficiency.

[0034] It should be noted that, for those skilled in the art, it is obvious that this utility model is not limited to the details of the above exemplary embodiments, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this utility model. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this utility model is defined by the appended claims rather than the foregoing description. Therefore, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within this utility model, and no reference numerals in the claims should be construed as limiting the scope of the claims.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
