Description

Technical Field

[0001] This utility model relates to the field of motor assembly equipment technology, and in particular to a heavy-duty motor sleeve assembly device. Background Technology

[0002] In high-speed, high-load applications, an interference fit is typically used between the motor housing and the bushing to ensure stable connection. This requires significant pressing force when assembling the bushing and motor housing, especially when both are made of metal. Existing manual presses use a gear and rack mechanism to drive the pressure bar. Under impact loads, stress concentration at the tooth roots of the gear and rack can lead to fracture. While negative displacement design or increasing the module to enhance the gear and rack structure's strength would significantly increase the structural volume and weight, this approach would not be feasible.

[0003] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0004] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a heavy-duty motor sleeve assembly device to improve the high-load performance of manual presses.

[0005] The technical solution of this utility model is as follows:

[0006] A heavy-duty motor sleeve assembly device, the heavy-duty motor sleeve assembly device comprising:

[0007] Base plate, which supports the workpiece;

[0008] The crossbeam is connected to the base plate via columns;

[0009] A reinforcing column is provided on the base plate; the upright column passes through the reinforcing column;

[0010] A pressure rod passes through the reinforcing column; a first limiting groove is provided on the pressure rod along its length.

[0011] A swing arm is rotatably connected to the crossbeam at one end; the rotation plane of the swing arm coincides with the axis of the pressure rod; a second limiting groove is formed on the swing arm along its length.

[0012] The column and the pressure rod are arranged perpendicular to the base plate; a limiting screw is provided on the reinforcing column; the limiting screw passes through the first limiting groove; the end of the pressure rod away from the base plate passes through the crossbeam; a sliding screw is provided on the pressure rod passing through the crossbeam, and the sliding screw passes through the second limiting groove.

[0013] A first insertion hole is provided on the base plate. The first insertion hole is a blind hole. The column extends into the first insertion hole.

[0014] Perpendicular to the base plate, the reinforcing column has a first fixing hole and a second fixing hole in parallel; the column passes through the reinforcing column along the first fixing hole; the pressure rod passes through the reinforcing column along the second fixing hole.

[0015] The crossbeam is provided with a second insertion hole, which is a blind hole; the column extends into the second insertion hole.

[0016] A bent portion extends from the side away from the base plate, and the swing arm is rotatably connected to the bent portion.

[0017] At the end of the bent portion, two extension portions are provided in parallel, with a gap between the two extension portions; the swing arm extends into the gap.

[0018] A limiting ring is provided on the pressure bar between the reinforcing column and the crossbeam; an elastic element is sleeved on the pressure bar between the limiting ring and the reinforcing column.

[0019] A slider is provided at the end of the pressure rod away from the base plate, and a groove is formed on the slider; the swing arm passes through the slider along the groove; and the sliding screw is provided on the slider.

[0020] The end of the swing arm away from the crossbeam bends toward the side closer to the pressure bar.

[0021] An adjusting screw is also provided on the crossbeam; the adjusting screw is set perpendicular to the base plate; the axis of the adjusting screw is in the rotation plane of the swing arm.

[0022] The beneficial technical effects of this utility model are as follows:

[0023] (1) In the heavy-duty motor sleeve assembly device of this utility model, the rotation plane of the swing arm coincides with the axis of the pressure rod. When the pressure rod is driven to move, the swing arm is directly rotated, and the pressure rod is directly squeezed by the swing arm, driving the pressure rod to squeeze the bushing to the installation position. By extending the length of the swing arm, the length of the lever arm between the swing arm and the pressure rod can be increased, so that the pressure rod can be squeezed by the swing arm with greater force. If the strength of the swing arm is insufficient, the volume of the swing arm can be directly increased. The swing arm with a larger volume has greater structural strength and greater self-weight. The self-weight of the swing arm is directly superimposed on the pressure rod, which makes it easier to press the bushing into the installation position with greater force by the pressure rod. At the same time, a second limiting groove is opened on the swing arm, and the swing arm is connected to the pressure rod through the second limiting groove. The pressure rod is also limited in its travel by the limiting screw, thereby limiting the swing travel of the swing arm, avoiding excessive swing amplitude of the swing arm, and reducing the occurrence of safety accidents.

[0024] (2) Furthermore, a first insertion hole is provided on the base plate. While the column is limited by the first fixing hole, the base plate further restricts the position of the column through the first insertion hole, thereby improving the stability of the column fixation. Moreover, the column is inserted into the base plate and the reinforcing column, which facilitates the replacement of the column and the maintenance of the heavy motor sleeve assembly device.

[0025] (3) Furthermore, the swing arm is connected to the crossbeam through a bend. The bend moves the center of rotation of the swing arm away from the base plate, thus avoiding interference between the swing arm and the crossbeam when the swing arm rotates. Attached Figure Description

[0035] The heavy-duty motor sleeve assembly device includes a base plate 1, which supports the workpiece; a crossbeam 4, connected to the base plate 1 via a column 3; a reinforcing column 2, mounted on the base plate 1; a column 3 passing through the reinforcing column 2; a pressure rod 5, passing through the reinforcing column 2; and a first limiting groove 51 formed on the pressure rod 5 along its length; and a swing arm 6, rotatably connected to the crossbeam 4 at one end. The rotation plane of the swing arm 6 coincides with the axis of the pressure rod 5. When the pressure rod 5 is moved, the swing arm 6 is rotated directly, directly pressing the pressure rod 5 and driving the pressure rod 5 to press the sleeve into the installation position. Extending the length of the swing arm 6 increases the length of the lever arm between the swing arm 6 and the pressure rod 5, allowing for greater force to press the pressure rod 5. If the strength of the swing arm 6 is insufficient, its volume can be increased. A larger volume swing arm 6 has greater structural strength and a greater self-weight, which is directly superimposed on the pressure rod 5, facilitating a greater force to press the sleeve into the installation position. Along the length of the swing arm 6, a second limiting groove 61 is formed on the swing arm 6. The column 3 and the pressure rod 5 are set perpendicular to the base plate 1. A limiting screw 221 is installed on the reinforcing column 2. The limiting screw 221 passes through the first limiting groove 51. The end of the pressure rod 5 away from the base plate 1 passes through the crossbeam 4. A sliding screw 542 is installed on the pressure rod 5 passing through the crossbeam 4, and the sliding screw 542 passes through the second limiting groove 61. The crossbeam 4 is connected to the pressure rod 5 through the second limiting groove 61. The movement of the pressure rod 5 is simultaneously limited by the limiting screw 221, thereby limiting the swing stroke of the swing arm 6, preventing excessive swing amplitude of the swing arm 6, and reducing the occurrence of safety accidents.

[0036] A first insertion hole 11 is provided on the base plate 1. The first insertion hole 11 is a blind hole. The column 3 extends into the first insertion hole 11. While the column 3 is limited by the first fixing hole 21, the base plate 1 further restricts the position of the column 3 through the first insertion hole 11, improving the stability of the column 3. Moreover, the column 3 intersects with the base plate 1 and the reinforcing column 2, which facilitates the replacement of the column 3 and the maintenance of the heavy motor sleeve assembly device.

[0037] Preferably, a first fixing hole 21 and a second fixing hole 22 are provided parallel to each other on the reinforcing column 2, perpendicular to the base plate 1. The column 3 passes through the reinforcing column 2 along the first fixing hole 21. The pressure rod 5 passes through the reinforcing column 2 along the second fixing hole 22. The first fixing hole 21 and the second fixing hole 22 restrict the position of the pressure rod 5 of the column 3.

[0038] In some embodiments, an adjusting screw 43 is also provided on the crossbeam 4. The adjusting screw 43 is disposed perpendicular to the base plate 1. The axis of the adjusting screw 43 lies in the rotation plane of the swing arm 6. The adjusting screw 43 limits the swing range of the swing arm 6, preventing the swing arm 6 from directly contacting and damaging the crossbeam 4.

[0039] A second insertion hole 41 is provided on the crossbeam 4. The second insertion hole 41 is a blind hole. The column 3 extends into the second insertion hole 41. The column 3 and the second insertion hole 41 are interference-fitted to connect the crossbeam 4 and the column 3.

[0040] Preferably, a bend 42 extends from the crossbeam 4 away from the base plate 1, and the swing arm 6 is rotatably connected to the bend 42. The bend 42 allows the swing arm 6 to move its rotational weight away from the base plate 1, thus preventing interference between the swing arm 6 and the crossbeam 4 when it rotates.

[0041] More preferably, at the end of the bent portion 42, two extension portions 421 are provided in parallel, with a gap 422 between the two extension portions 421. The swing arm 6 extends into the gap 422. The two extension portions 421 limit the range of movement of the swing arm 6 and enhance the strength of the connection between the crossbeam 4 and the swing arm 6.

[0042] A limiting ring 52 is installed on the pressure bar 5 between the reinforcing column 2 and the crossbeam 4. An elastic element 53 is sleeved on the pressure bar 5 between the limiting ring 52 and the reinforcing column 2. After the swing arm 6 descends and presses the pressure bar 5, the elastic element 53 stores elastic potential energy. After the operator no longer drives the swing arm 6 to swing, the elastic element 53 rebounds and pushes the swing arm 6 and the pressure bar 5 back to their original positions, realizing automatic reset.

[0043] Preferably, a slider 54 is provided at the end of the pressure rod 5 away from the base plate 1, and a groove 541 is formed on the slider 54. The swing arm 6 passes through the slider 54 along the groove 541. A sliding screw 542 is provided on the slider 54. The slider 54 restricts the degree of freedom of the swing arm 6 through the groove 541, thereby improving the connection strength between the swing arm 6 and the slider 54.

[0044] More preferably, the end of the swing arm 6 furthest from the crossbeam 4 is bent towards the side closer to the pressure rod 5. Lowering the height of the swing arm 6 makes it easier for the operator to press the swing arm 6 and drive it to rotate.

[0045] The specific workflow of this utility model is as follows:

[0046] When pressing the bushing, first, according to the size and model of the bushing, rotate the adjusting screw 43 to adjust the relative position of the crossbeam 4 and the adjusting screw 43. Then move the base plate 1 below the bushing's pressure rod 5. The operator presses down on the swing arm 6 until the swing arm 6 contacts the adjusting screw 43. At this time, the bushing is pressed into the installation position by the pressure rod 5. Finally, the operator releases the swing arm 6, and the elastic element 53 releases its elastic force. The elastic element 53 drives the pressure rod 5 upward by pushing the limiting ring 52, and at the same time drives the swing arm 6 to swing upward until the elastic element 53 tends to be balanced, completing the automatic reset of the pressure rod 5 and the swing arm 6. During the automatic reset process, the sliding screw 542 slides in the second limiting groove 61. The second limiting groove 61 cooperates with the sliding screw 542 to limit the swing angle of the swing arm 6.

[0047] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0048] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
