Description

Technical Field

[0001] This utility model relates to the field of motor manufacturing and processing technology, and in particular to a device for pressing together the end cover and housing of a DC motor. Background Technology

[0002] In the dispensing process of DC motor production, adhesive is applied to the top of the motor housing to meet installation tightness and sealing requirements at the joint between the motor end cover and the motor housing. The motor end cover is then pressed onto the housing. Currently, manual hammering is used to connect the end cover and the housing. However, this method can lead to uneven force on the end cover during hammering, affecting the connection. Therefore, a pressing device is now widely used to connect the end cover and the housing. The existing pressing device works by using a clamp to fix the motor housing, then placing the end cover on the housing, and finally using a drive device to press down a pressure plate to press the end cover onto the housing. However, a drawback is that the drive device can easily apply excessive pressure during the pressing process, potentially damaging the end cover. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a DC motor end cover and housing pressing device, which solves the problem that existing pressing devices are prone to damaging the end cover during the pressing process between the motor end cover and the housing.

[0004] According to an embodiment of this utility model, a DC motor end cover and housing pressing device includes: a base, a mounting plate, and a crossbeam. A support bracket is provided at the bottom of the base, and two side plates are symmetrically arranged at the top of the base. The crossbeam is fixed between the two side plates, and a hydraulic cylinder is mounted on the crossbeam. The output end of the hydraulic cylinder extends vertically downwards, and the mounting plate is horizontally fixed to the output end of the hydraulic cylinder. Several sets of clamping assemblies for clamping the motor housing are provided at the top of the base. A driving assembly for driving each clamping assembly to clamp or release the motor housing is provided on the support bracket. A pressing assembly is provided on the top of the mounting plate directly above each clamping assembly. Each pressing assembly includes: a mounting post, an elastic contraction mechanism, and a pressing plate. The mounting post is vertically fixed to the bottom of the mounting plate, and a mounting groove is provided at the bottom of the mounting post. One end of the elastic contraction mechanism is disposed in the mounting groove, and the pressing plate is horizontally fixed to the other end of the elastic contraction mechanism.

[0005] Compared with the prior art, this utility model has the following advantages: by setting several sets of clamping components on the top of the base to clamp the motor housing, and then fastening the end cover on the housing, the mounting plate is driven down by the hydraulic cylinder, the mounting plate pushes the pressing plate down, and the pressing plate pushes the end cover to press it onto the motor housing. By setting an elastic contraction mechanism in the mounting groove of the mounting column, a buffering effect can be achieved to prevent the pressing plate from damaging the end cover due to excessive driving force of the hydraulic cylinder.

[0006] Each of the aforementioned elastic contraction mechanisms includes: a spring and a connecting column, one end of which is slidably disposed in the mounting groove, the spring being connected between the top of the mounting groove and the top of the connecting column, and the bottom end of the connecting column being fixedly connected to the pressing plate.

[0007] Each of the aforementioned press plates has a rubber pad at its bottom.

[0008] Each of the clamping components includes a clamping seat and a sliding seat, wherein the clamping seat is fixedly disposed on the top of the base and the sliding seat is slidably disposed on the top of the base.

[0009] The drive assembly includes a drive motor and a lead screw. The lead screw is horizontally and rotatably mounted on the bracket. The drive motor is mounted on one side of the bracket. The output end of the drive motor is fixedly connected to the end of the lead screw. One end of a sliding rod is fixedly connected to the bottom of each sliding seat. The other end of the sliding rod is sleeved on the lead screw. Each sliding rod is threadedly connected to the lead screw.

A hydraulic cylinder 5 is provided on the crossbeam 4, and the output end of the hydraulic cylinder 5 extends vertically downward. The mounting plate 6 is horizontally fixed to the output end of the hydraulic cylinder 5. The top of the base 1 is provided with several sets of clamping components for clamping the motor housing. The support bracket 2 is provided with a driving component that drives each clamping component to clamp or release the motor housing. A pressing component is provided on the top of the mounting plate 6 directly above each clamping component. Each pressing component includes: a mounting post 7, an elastic contraction mechanism, and a pressing plate 9. The mounting post 7 is vertically fixed to the bottom of the mounting plate 6, and the bottom of the mounting post 7 is provided with a mounting groove 8. One end of the elastic contraction mechanism is provided in the mounting groove 8, and the pressing plate 9 is horizontally fixed to the other end of the elastic contraction mechanism.

[0016] The motor housing is clamped by several sets of clamping components set on the top of the base 1. Then the end cover is fastened on the housing. The mounting plate 6 is driven to press down by the hydraulic cylinder 5. The mounting plate 6 pushes the pressing plate 9 down. The pressing plate 9 pushes the end cover to press it onto the motor housing. By setting an elastic contraction mechanism in the mounting groove 8 of the mounting column 7, a buffering effect can be achieved to prevent the pressing plate 9 from damaging the end cover due to excessive driving force of the hydraulic cylinder 5.

[0017] like Figure 2 As shown, each of the elastic contraction mechanisms includes a spring 11 and a connecting post 10. One end of the connecting post 10 is slidably disposed in the mounting groove 8. The spring 11 is connected between the top of the mounting groove 8 and the top of the connecting post 10. The bottom end of the connecting post 10 is fixedly connected to the pressing plate 9. The spring 11 can buffer the pressing plate 9 to prevent excessive pressure on the pressing plate 9 from damaging the end cap. A rubber pad 12 is also provided at the bottom of the pressing plate 9, which can also protect the end cap.

[0018] Furthermore, each of the clamping components includes a clamping seat 13 and a sliding seat 14. The clamping seat 13 is fixedly disposed on the top of the base 1, and the sliding seat 14 is slidably disposed on the top of the base 1. The driving component includes a driving motor 15 and a lead screw 16. The lead screw 16 is horizontally and rotatably disposed on the bracket 2.

One end of a sliding rod 17 is fixedly connected to the bottom of each sliding seat 14. The other end of the sliding rod 17 is sleeved on the lead screw 16. Each sliding rod 17 is threadedly connected to the lead screw 16. The top of the base 1 is provided with a plurality of sliding grooves for the sliding rods 17 to slide in the horizontal direction.

[0019] Specifically, the drive motor 15 drives the lead screw 16 to rotate, and the lead screw 16 drives the sliding rod 17 to move horizontally to the left or right. The sliding rod 17 drives the sliding seat 14 to move closer to or away from the clamping seat 13, thereby achieving the clamping or release of the motor housing. In this way, multiple motor end covers can be installed at one time, improving the pressing efficiency of the motor end covers.

[0020] Furthermore, mounting bases 18 are fixedly provided at both ends of the mounting plate 6, and rollers 19 are rotatably provided on the opposite sides of the two mounting bases 18. The two rollers 19 are respectively connected to the side walls of the two side plates 3, thereby guiding the vertical movement of the mounting plate 6.
