Description

Technical Field

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

[0002] A sleeve needs to be installed on the end cover of the motor, and the end cover is rotatably connected to the shaft via the sleeve. The sleeve compensates for the thermal expansion of the shaft and its components, and the sleeve itself is replaceable, simplifying the motor maintenance process. The end cover and sleeve have an interference fit, and installing the sleeve requires sufficient pressure and the selection of appropriate pressure stroke and pressure angle. When installing sleeves in small batches, the cost of automated equipment is too high. Manual assembly by operators is inefficient, wastes manpower, and has an excessively long production cycle. It should be noted that the information disclosed in the above background section is only for enhancing 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

[0003] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a motor shaft sleeve assembly device to balance assembly efficiency and investment cost.

[0004] The technical solution of this utility model is as follows:

[0005] A motor shaft sleeve assembly device, comprising:

[0006] The base supports the workpiece;

[0007] A crossbeam is connected to the base via a column; a drive shaft is mounted on the crossbeam.

[0008] A pressure rod is mounted on the crossbeam perpendicular to the base; the pressure rod is slidably connected to the base along its length, and a driven tooth is provided on the pressure rod; a driving tooth is provided circumferentially on the drive shaft; the driving tooth meshes with the driven tooth.

[0009] The crossbeam is also provided with a limit rod, and the pressure rod and the limit rod are slidably connected; the limit rod is provided with an elastic element and a limit block; the elastic element is connected to the pressure rod, and the elastic element and the limit block are located on the side of the pressure rod away from the crossbeam.

[0010] A further technical solution is that a fixing block extends from the base; an arc-shaped clamp is provided on the surface of the fixing block near the column to hold the column.

[0011] A further technical solution is that a fixing hole is opened on the base, and the column extends into the fixing hole.

[0012] A further technical solution is that a protrusion is provided at the end of the pressure rod near the base; when the sleeve is installed, the protrusion extends into the through hole of the sleeve.

[0013] A further technical solution is that the limiting rod is arranged parallel to the pressure rod; a slider is provided at the end of the pressure rod away from the base, and the slider is slidably connected to the limiting rod.

[0014] A further technical solution is that the end of the limiting rod away from the base is bent to form a bent portion; the elastic element connects the bent portion to the limiting rod.

[0015] A further technical solution is that the limiting rod is threadedly connected to the crossbeam.

[0016] A further technical solution is that a first limiting screw is provided on the limiting block; the first limiting screw passes through the limiting block and is then driven into the limiting rod.

[0017] A further technical solution is that a handle is provided on the drive shaft along its radial direction.

[0018] A further technical solution is that a second limiting screw is provided on the crossbeam, and the second limiting screw passes through the crossbeam and is nailed into the column.

[0019] The beneficial technical effects of this utility model are as follows:

[0020] (1) The motor shaft sleeve assembly device of this utility model has a sliding pressure rod that meshes with the drive shaft. Driving the drive shaft to rotate drives the pressure rod to slide back and forth along the crossbeam, pressing the sleeve into the installation position. The pressure rod slides along a preset trajectory, preventing deviation in the direction of the pressure applied by the pressure rod and eliminating the need for operators to repeatedly determine the angle of pressure application. Simultaneously, the pressure of the pressure rod is directly transmitted by the drive shaft, facilitating adjustments to the assembly pressure by the operator. Furthermore, the limiting rod is also designed with an elastic element and a limiting block. When the pressure rod is driven downwards for assembly, the elastic element can automatically reset the pressure rod, simplifying operation and significantly improving the working efficiency of the motor shaft sleeve assembly device. The limiting block restricts the stroke of the pressure rod, preventing it from being too small to perform the assembly action properly, and also preventing it from being too large, resulting in excessive wasted stroke and hindering overall work efficiency.

[0021] (2) Furthermore, the base is provided with fixing holes, and the fixing block is also provided with arc-shaped clamps. The fixing holes and arc-shaped clamps work together to fix the column at multiple points, thereby improving the strength and stability of the column fixing.

[0022] (3) Furthermore, the limiting block is slidably set on the limiting rod. By adjusting the position of the limiting block along the limiting rod, the sliding stroke of the pressure rod can be quickly adjusted. The adjustment is simple and improves the flexibility of the motor shaft sleeve assembly device to adapt to the installation of sleeves of different sizes and specifications.

[0031] Figure 1 The diagram shows a front view of a motor shaft sleeve assembly device according to an embodiment of the present disclosure, with the pressure rod moved to the top of its stroke. Figure 2 The diagram shows a front view of a motor shaft sleeve assembly device according to an embodiment of the present disclosure, with the pressure rod moved to the bottom of its stroke. Figure 3 A schematic diagram of the mating structure between the drive shaft and the pressure rod in a motor shaft sleeve assembly device according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3 The motor shaft sleeve assembly device includes a base 1 for supporting the workpiece, a crossbeam 3 connected to the base 1 via a column 2, a drive shaft 51 mounted on the crossbeam 3, and a pressure rod 4 mounted perpendicular to the base 1 on the crossbeam 3. The pressure rod 4 is slidably connected to the base 1 along its length, and has a driven tooth 41. The drive shaft 51 has a circumferentially ... The elastic element 61 is located on the outside of the crossbeam 3 for easy observation and maintenance by operators. The elastic element 61 connects to the pressure rod 4, and the elastic element 61 and the limiting block 62 are located on the side of the pressure rod 4 away from the crossbeam 3. When the pressure rod 4 is driven downwards for assembly, the elastic element 61 can drive the pressure rod 4 to automatically reset, simplifying operation and significantly improving the working efficiency of the motor shaft sleeve assembly device. The limiting block 62 restricts the stroke of the pressure rod 4, preventing it from being too short and unable to perform the assembly action properly, and also preventing it from being too long and having too much unnecessary stroke, which would drag down the overall working efficiency.

[0032] In some embodiments, the elastic element 61 may be a spring.

[0033] Figure 4 This diagram shows a top view of the base in a motor shaft sleeve assembly device according to an embodiment of the present disclosure. Please refer to... Figure 1 and Figure 4 A fixing block 11 extends from the base 1. An arc-shaped clamping plate 111 is provided on the surface of the fixing block 11 near the column 2 to clamp the column 2. In this embodiment, two arc-shaped clamping plates 111 are symmetrically arranged around the axis of the column 2. The arc surface of the arc-shaped clamping plate 111 is in contact with the outer arc surface of the column 2, and the two arc-shaped clamping plates 111 cooperate to fix the position of the column 2.

[0034] Meanwhile, fixing holes 12 are made on the base 1, and the column 2 extends into the fixing holes 12. The fixing holes 12 and the arc-shaped clamping plate 111 work together to fix the column 2 at multiple points, improving the strength and stability of the column 2.

[0035] In some embodiments, a protrusion 42 is provided at the end of the pressure rod 4 near the base 1. When the sleeve is installed, the protrusion 42 extends into the through hole of the sleeve to position the relative position of the sleeve and the pressure rod 4.

[0036] Please refer to Figure 1 and Figure 2 The limiting rod 6 is set parallel to the pressure rod 4. A slider 43 is set at the end of the pressure rod 4 away from the base 1, and the slider 43 is slidably connected to the limiting rod 6. The limiting rod 6 guides the sliding trajectory of the pressure rod 4 and enhances the stability of the pressure rod 4 when sliding.

[0037] Preferably, the end of the limiting rod 6 away from the base 1 is bent to form a bent portion 7. The elastic element 61 is connected to the bent portion 7 and the limiting rod 6 to ensure that the extension and retraction direction of the elastic element 61 coincides with the sliding direction of the pressure rod 4, so as to facilitate the elastic element 61 to pull the reset pressure rod 4.

[0038] In some embodiments, the limiting rod 6 is threadedly connected to the crossbeam 3, which allows for quick connection between the limiting rod 6 and the crossbeam 3, while also facilitating adjustment of the height of the limiting rod 6. This, in turn, allows for overall adjustment of the elastic force of the elastic element 61 and the sliding stroke of the pressure rod 4, thereby improving the flexibility of the motor shaft sleeve assembly device.

[0039] Please refer to Figure 1 and Figure 2 A first limiting screw 621 is provided on the limiting block 62. The first limiting screw 621 passes through the limiting block 62 and is driven into the limiting rod 6. The limiting block 62 and the limiting rod 6 are movably connected, which facilitates the adjustment of the position of the limiting block 62 along the limiting rod 6, thereby adjusting the stroke of the pressure rod 4 and improving the flexibility of the motor shaft sleeve assembly device.

[0040] In some embodiments, a handle 5 is provided on the drive shaft 51 along its radial direction. When an operator drives the drive shaft 51 to rotate via the handle 5, the handle 5 significantly amplifies the force applied by the operator through a lever arm. This simplifies and makes rotating the drive shaft 51 more efficient.

[0041] In some embodiments, a second limiting screw 31 is provided on the crossbeam 3. The second limiting screw 31 passes through the crossbeam 3 and is driven into the column 2 to movably connect the crossbeam 3 and the column 2, facilitating the adjustment of the position of the crossbeam 3 along the column 2 and improving the flexibility of the motor shaft sleeve assembly device. In this embodiment, the second fastening screw can be a fastening screw with a handle 5.

[0042] The specific workflow of this utility model is as follows:

[0043] The operator first moves the end cap onto the base 1 and then moves the sleeve so that the protrusion 42 extends into the through hole of the sleeve, vertically aligning the sleeve with the installation position of the end cap. Then, the operator pulls the handle 5, which drives the pressure rod 4 downwards via the active tooth 511 and the driven tooth 41. The downward-moving pressure rod 4 presses the sleeve into the installation position of the end cap. At this point, the operator releases the handle 5, and the elastic element 61 rebounds, pulling up the pressure rod 4 until the slider 43 contacts the limit block 62. The pressure rod 4 then automatically resets, completing the installation of one sleeve.

[0044] 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.

[0045] 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.
