Description

Technical Field

[0001] This utility model relates to an axial pressing device for motor workpieces, belonging to the field of electric motor assembly technology. Background Technology

[0002] A motor is a device that converts energy in the form of electricity, pneumatic energy, or hydraulic energy into mechanical energy. It is widely used in industrial manufacturing, transportation, and home appliances. Its basic structure typically includes a stator, rotor, bearings, and housing. The stator generates a magnetic field through an electric current, and the rotor rotates under the influence of the magnetic field, thereby driving the mechanical equipment.

[0003] Existing motors are equipped with pre-made gears before leaving the factory. The industry commonly uses a press-fit method, where the gear and motor are fitted with a transition fit. The steps are as follows: the motor is fixed to a tooling table, the inner diameter of the gear is clamped and aligned with the motor output shaft using a tool, and then the gear is pushed onto the motor output shaft using a pressing tool. However, the gear is very prone to misalignment, causing the inner diameter of the gear to expand during the press-fit process, resulting in poor accuracy of the transition fit, an unreliable connection between the motor output shaft and the gear, and low assembly efficiency.

After the pin contacts the motor's output shaft, the pressing assembly continues to press down. The outer edge of the movable slot pushes the motor gear into the motor's output shaft, while the pin is pushed into the movable slot by the motor's output shaft. At this point, the pin retracts along the movable slot, preventing misalignment when the motor gear is pressed down onto the motor's output shaft.

[0038] Example

[0039] This embodiment aims to address the shortcomings of existing press-fitting methods for gears, which are prone to misalignment. This causes the gear's inner diameter to expand during the press-fitting process, leading to decreased precision in the transition fit, unreliable connection between the motor output shaft and the gear, and low assembly efficiency. Therefore, referring to... Figure 1-3 As shown, this embodiment provides an axial pressing device for a motor workpiece. A pin 3 is provided in the pressing device 2. The pin 3 can be inserted into the motor gear 200, and the axis of the pin 3 corresponds to the axis of the mounting station 11, that is, it is adapted to the size of the motor output shaft and is coaxial. The power component 4 can drive the pressing assembly 21 to move towards the motor in the mounting station 11. After the pin 3 is aligned and contacted with the output shaft of the motor, the pressing assembly 21 continues to press down. The outer edge of the port of the movable through groove 211 can push the motor gear 200 into the output shaft of the motor. At the same time, the pin 3 is pushed into the movable through groove 211 by the output shaft of the motor. At this time, the pin 3 is guided and retracted along the movable through groove 211. Therefore, when the motor gear 200 is pressed down to the output shaft of the motor, it is not easy for it to deviate. That is, when one end of the motor gear 200 is inserted, the other end is not easily deviated from the axis. This avoids the inner diameter of the gear from expanding during pressing, and improves assembly efficiency and quality.

[0040] Reference Figure 1-3 As shown, an axial pressing device for a motor workpiece includes: a base 1, a pressing device 2, a pin 3, and a power component 4. The base 1 includes a mounting station 11 located on the top of its main body, which can hold a motor. For example, the mounting station 11 is an annular protrusion 12, the size of which is adapted to the diameter of the motor. One side of the annular protrusion 12 has an opening slot 13 for the motor's wires to be led out. Thus, the annular protrusion 12 can position and mount the bottom of the motor 100, and its wires can be led out from the opening slot 13.

[0041] The axial pressing device for the motor workpiece also includes a pressing device 2 mounted on the base 1, the pressing device 2 including a pressing assembly 21. A through movable slot 211 is provided in the middle of the pressing assembly 21, the movable slot 211 being vertically downward and aligned with the mounting position 11; wherein the size of the pin 3 is adapted to the output shaft of the motor 100, i.e., using the same diameter; the pin 3 is slidably connected to the movable slot 211, the movable slot 211 guiding the pin 3 to slide vertically, and at least a portion of the pin 3 protrudes from the bottom of the pressing assembly 21, i.e., exposing the movable slot 211, exposing the movable slot 211. At least a portion of the pin 3 in slot 211 can be fitted into the motor gear 200; the axis of the pin 3 corresponds to the axis of the mounting station 11; the press-fit principle is to align the pin 3 with the output shaft of the motor, and the outer edge of the port of the movable through slot 211 can continuously press down to push the motor gear 200 from the pin 3 onto the motor output shaft. During the pressing process, the pin 3 can retract into the movable through slot 211 to guide the assembly and prevent the pressed motor gear 200 from radially shifting. The bottom of the power component 4 is detachably connected to the top of the pressing assembly 21; the power component 4 can drive the pressing assembly 21 to move towards the motor in the mounting station 11 and push the motor gear 200 into the motor output shaft, while the pin 3 pushes the motor output shaft into the movable through slot 211. For example, the pin 3 includes a locking shaft disposed within the movable through slot 211 and an insert shaft located outside the movable through slot 211, with a magnetic connection between the insert shaft and the locking shaft; thus, after completing one assembly of the motor gear 200, another insert shaft with another motor gear 200 can be replaced for the assembly of the next motor. For example, the power component 4 can be a cylinder slide, a lead screw slide, or a hydraulic slide, capable of driving the pressing device 2 to move up and down.

[0042] Reference Figure 1-3 As shown, the pressing assembly 21 further includes a support plate 212 and a pressing cylinder 213. The support plate 212 is detachably connected to the power component 4. A movable through groove 211 is provided in the middle of the pressing cylinder 213; the pin 3 has a limiting protrusion 31 at its end located within the movable through groove 211, and the inner wall of the movable through groove 211 is provided with a guide rail adapted to the limiting protrusion 31; the top of the pressing cylinder 213 is detachably connected to the support plate 212.

[0043] Reference Figure 1-3As shown, the pressing cylinder 213 includes a first cylinder 213a, a second cylinder 213b sleeved on the first cylinder 213a, and a travel limiting member 213c. The second cylinder 213b can extend and retract relative to the bottom of the first cylinder 213a, and the pin 3 can retract into the movable through groove 211 of the second cylinder 213b. The travel limiting member 213c is detachably connected to the top of the first cylinder 213a, and at least a portion of the travel limiting member 213c can extend into the movable through groove 211 of the first cylinder 213a. The end of the travel limiting member 213c can limit the sliding of the second cylinder 213b relative to the first cylinder 213a. It should be noted that after the pin 3 abuts against the motor's output shaft, the power component 4 continuously drives the pressing device 2 to move downwards. The second cylinder 213b slides and retracts relative to the first cylinder 213a until it abuts against the travel limit component 213c, achieving hard contact. The outer edge of the port of the second cylinder 213b can push the motor gear 200 from the position of the pin 3 into the motor's output shaft. It should be added that the sliding and retracting of the second cylinder 213b relative to the first cylinder 213a can serve as a buffer stroke. The pin 3 can first abut against the motor's output shaft, buffer a stroke, and then achieve top-to-top insertion. Before operation, the motor gear 200 configured on the pin 3 is usually not penetrated through the entire motor gear 200. Instead, the pin 3 is inserted from one end to the chamfered tail of the other end, leaving the chamfered port unused. When connecting the motor's output shaft, this chamfer can effectively guide the motor's output shaft to align with the pin 3.

[0044] Reference Figure 1-3 As shown, the motor workpiece axial pressing device also includes a pressure-stopping component 5, which is used to control the power component 4 to stop and output in reverse when the motor gear 200 is fully inserted into the output shaft of the motor. The pressure-stopping component 5 is detachably connected to the pressing component 21.

[0045] The pressure-stopping assembly 5 includes a pressure sensor 51, a controller, and a stop member 52. The pressure sensor 51 is electrically connected to the controller; the controller is electrically connected to the power component 4, and the controller can receive pressure information from the pressure sensor 51 and control the opening and closing of the power component 4; the stop member 52 is connected to the power component 4 via the pressure sensor 51; the position of the stop member 52 corresponds to the end face of the motor at the installation station 11. When the motor gear 200 is fully pushed into the motor's output shaft, the bottom of the stop member 52 contacts the end face of the motor, simultaneously pressing against the pressure sensor 51. The pressure sensor 51 transmits pressure information to the controller. When the pressure information exceeds a preset threshold, the controller controls the power component 4 to stop and reverse its output, causing the output end of the power component 4 to return to its initial position.

[0046] The support plate 212 includes a first support plate 212a and a second support plate 212b, which are detachably connected by at least two first connecting rods 214. A sandwich space is formed between the first support plate 212a and the second support plate 212b for placing a pressure sensor. The abutment member 52 includes a third support plate 521 disposed between the first support plate 212a and the second support plate 212b, and a fourth support plate 522 disposed below the second support plate 212b. The top of the pressure sensor 51 is connected to the bottom of the first support plate 212a, and the bottom of the pressure sensor 51 is connected to the top of the third support plate 521.

[0047] The fourth support plate 522 is detachably connected to the third support plate 521 via at least two second connecting rods 53. The second support plate 212b is provided with multiple through holes adapted to the at least two second connecting rods 53, each capable of passing through one of the two connecting rods 53. The fourth support plate 522 is provided with a passage slot for the pressing assembly 21 to pass through. The through holes and the at least two second connecting rods 53 are relatively slidable. While the power component 4 pushes the support plate 212 downwards, the abutment member 52 and the pressing cylinder 213 operate independently. The abutment member 52 does not interfere with the pressing cylinder 213's process of installing the motor gear 200. When the abutment member 52 abuts against the end face of the non-central part of the motor top, the pressure sensor 51 is triggered, the power component 4 stops forward output, the pressing of the motor gear 200 is completed, and the controller outputs a reverse command to the power component 4. For example, refer to... Figure 1-3 As shown, the abutment member 52 also includes an abutment sleeve for abutting against the end face of the non-central part of the top of the motor. The abutment sleeve is detachably connected to the bottom of the fourth support plate 522. The inner diameter of the abutment sleeve is adapted to the passage slot, and the diameter of the passage slot is larger than that of the motor gear 200.

The top of the workpiece positioning component 14 is provided with an installation station 11; the top surface of the worktable 15 is detachably connected to the positioning component; the top of the base body is detachably connected to the worktable 15.

[0049] Reference Figure 1-3 As shown, the pressing device 2 also includes a control box 6, which is connected to the base 1 via a support beam 7 so that the control box 6 can be supported directly above the base 1; the bottom of the control box 6 is provided with a power output window, and the power component 4 is located inside the control box 6, with the output end of the power component 4 extending out of the control box 6 through the power output window.
