Description

Technical Field

[0001] This utility model belongs to the field of motor assembly, specifically, it relates to a motor that is easy to install. Background Technology

[0002] An electric motor is an electromagnetic device that converts or transmits electrical energy based on the law of electromagnetic induction, or converts one form of electrical energy into another. Its main function is to generate driving torque, serving as a power source for electrical appliances or various machines.

[0003] An electric motor generally consists of a housing, stator, rotor, rear end housing, and front end housing. To ensure the strength of the motor, the housing and end housings need to be made of metal with good protective properties, which results in a large weight. Therefore, it is quite troublesome for workers to assemble the housing, rear end housing, and front end housing. They need to lift the end housing with one hand and align it with the housing before screwing in the bolts. This requires a lot of physical strength from the assembler and is inconvenient. In view of this, this utility model is proposed. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a motor that is easy to install.

[0005] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by this utility model is as follows:

[0006] An easy-to-install motor includes a housing, a rotor, a front cover, and a rear cover. The housing has multiple stators inside. Both the front and rear ends of the housing have front and rear covers for mounting the rotor shafts. Both ends of the housing have insertion slots for mounting the front and rear covers. Alignment rods that match the internal dimensions of alignment holes are fixedly installed on both sides of the two insertion slots. The alignment holes are opened on the contact surfaces of the front and rear covers and the insertion slots.

[0007] The outer wall surfaces of the front and rear covers are provided with limiting holes for the spring pin head to abut against. The spring pin is installed on the outside of the housing. A clearance cavity for the spring pin head to move is provided in the middle of the housing. A positioning hole is provided through the middle of the spring pin rod.

[0008] Support blocks are fixed to the upper and lower exterior sides of the housing. A fixing rod is hinged to the end of each support block. The end of each fixing rod is placed in the middle of the U-shaped block. The end of the fixing rod is provided with threads that match the internal thread groove of the nut.

[0009] Optionally, both the front and rear covers have reserved slots in the middle for installing dustproof components. The dustproof components have dustproof nets in the middle, and the upper and lower ends of the dustproof components have slots on their outer sides that are adapted to the outer contour of the T-shaped rail. The T-shaped rail is fixed inside the reserved slots.

[0010] Optionally, the side of the reserved slot is fixed with an inner fixing ring for inserting an outer fixing ring, the outer fixing ring is fixed to the side of the dustproof component, and the surface of the inner fixing ring is provided with a groove for embedding an annular magnetic block.

[0011] Optionally, the front end cover has a through hole in the middle for the rotor shaft to pass through, and a first bearing is provided inside the through hole. The first bearing is limited by a screw and an annular cover.

[0012] Optionally, a support block is fixed on the inner side of the rear end cover for placing the other end shaft of the rotor. The support block is provided with a second bearing, and a heat dissipation blade is fixedly sleeved on the outside of the other end shaft of the rotor.

[0013] Optionally, the contact surfaces of the front end cover and the rear end cover with the embedded groove are both fixed with sealing elements, and the outer shape of the sealing elements is a ring structure design.

[0014] Optionally, the contact surfaces of the front cover and the rear cover with the embedded groove are each fixed with an annular telescopic airbag. The other end of the annular telescopic airbag abuts against the embedded groove, and the upper end of the annular telescopic airbag is connected to the air nozzle at the upper end of the front cover or the rear cover through a pipe. The lower end of the annular telescopic airbag is connected to the pressure gauge at the lower end of the front cover or the rear cover through a pipe.

[0015] Optionally, a support is fixed to the bottom of the housing, and a spirit level is fixed to the middle of the support.

[0016] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0017] This invention uses alignment holes and alignment rods to initially position the front and rear covers and the machine housing. At this point, the assembly worker does not need to use force to lift the front and rear covers; they only need to hold them, reducing the physical burden on the assembly worker. Next, the rod, which is pre-inserted into the positioning hole in the middle of the pin head, is removed. At this time, the pin head of the spring pin is inserted into the limiting hole, completing the secondary positioning. During the secondary positioning process, the assembly worker can free their hands to perform the third positioning. The third positioning only requires rotating the fixing rod to the middle of the U-shaped block and then tightening the nut so that the nut abuts against the U-shaped block. Compared with the existing method that requires aligning the front and rear covers with the machine housing before tightening the bolts, this method is more convenient and easier to assemble.

Detailed Implementation

[0030] The present invention will now be described in further detail with reference to the accompanying drawings.

[0031] Please see Figures 1 to 6This utility model provides a technical solution: a motor that is easy to install, including a housing 1, a rotor 3, a front cover 4 and a rear cover 5. The housing 1 is provided with multiple stators 2 inside. The front cover 4 and the rear cover 5 are provided at both ends of the housing 1 for mounting the shafts at both ends of the rotor 3. The housing 1 is provided with an embedding groove 6 at both ends for mounting the front cover 4 and the rear cover 5. Alignment rods 8 that are adapted to the internal size of alignment holes 7 are fixedly installed on both sides of the two embedding grooves 6. The alignment holes 7 are opened on the contact surfaces of the front cover 4 and the rear cover 5 and the embedding grooves 6.

[0032] Both the front cover 4 and the rear cover 5 have a limiting hole 10 on their outer wall surfaces for the head of the spring pin 9 to abut. The spring pin 9 is installed on the outside of the housing 1. The housing 1 has a clearance cavity 11 in the middle for the head of the spring pin 9 to move. The pin rod of the spring pin 9 has a positioning hole through the middle.

[0033] Support blocks 12 are fixed to the upper and lower exterior sides of the housing 1. A fixing rod 13 is hinged to the end of each support block 12. The end of each fixing rod 13 is placed in the middle of the U-shaped block 14. The end of the fixing rod 13 is provided with threads that match the internal thread groove of the nut 15. The alignment holes 7 and alignment rods 8 provide initial positioning between the front cover 4 and the rear cover 5 and the housing 1. At this time, the assembly worker does not need to use force to lift the front cover 4 and the rear cover 5, but only needs to hold them, which reduces the physical burden on the assembly worker. Next, the rod body pre-inserted into the positioning hole in the middle of the pin head is pulled out. At this time, the pin head of the spring pin is inserted into the limiting hole 10, and the second positioning is completed. During the second positioning process, the assembly worker can take out both hands to perform the third positioning. The third positioning only requires rotating the fixing rod 13 to the middle of the U-shaped block 14, and then tightening it with the nut 15 so that the nut 15 abuts against the U-shaped block 14. Compared with the existing method that requires aligning the front cover 4 and the rear cover 5 with the housing 1 before tightening the bolts, it is more convenient and easier to assemble.

[0034] The front cover 4 and the rear cover 5 both have reserved slots in the middle for the installation of the dustproof component 16. The dustproof component 16 has a dustproof net 17 in the middle, and the upper and lower ends of the dustproof component 16 are provided with slots 19 that are adapted to the outer contour of the T-shaped rail 18. The T-shaped rail 18 is fixed inside the reserved slot. By setting the dustproof component 16, the dust entering the machine housing 1 is isolated, ensuring that the inside of the device is not covered by dust and affecting its use.

[0035] The reserved slot has an inner fixing ring 21 fixed on its side for inserting the outer fixing ring 20. The outer fixing ring 20 is fixed to the side of the dustproof component 16. The surface of the inner fixing ring 21 has a groove for embedding the annular magnetic block 22. By setting the inner fixing ring 21 and the outer fixing ring 20, the front end cover 4 and the rear end cover 5 are quickly installed with the dustproof component 16. The presence of the annular magnetic block 22 strengthens the inner fixing ring 21 and the outer fixing ring 20 after docking. The magnetic force of the annular magnetic block 22 will be used to help fix the inner fixing ring 21 and the outer fixing ring 20.

[0036] The front cover 4 has a through hole in the middle for the shaft of one end of the rotor 3 to pass through. The first bearing 23 is provided inside the through hole, and the first bearing 23 is limited by screws in conjunction with the annular cover 24. The annular cover 24 plays a role in limiting the first bearing 23.

[0037] The inner side of the rear cover 5 is fixed with a support block 25 for placing the other end shaft of the rotor 3. The support block 25 is equipped with a second bearing 26, and the other end shaft of the rotor 3 is fixedly sleeved with a heat dissipation blade 27. The heat dissipation blade 27 is used to dissipate heat from the device.

[0038] Among them, the contact surfaces of the front cover 4 and the rear cover 5 with the embedded groove 6 are all fixed with sealing elements 28, and the outer shape of the sealing element 28 is a ring structure design. By setting the sealing element 28, the contact surfaces of the front cover 4 and the rear cover 5 with the embedded groove 6 are sealed.

[0039] Among them, the contact surfaces of the front cover 4 and the rear cover 5 with the embedded groove 6 are fixed with annular telescopic airbags 29. The other end of the annular telescopic airbag 29 abuts against the embedded groove 6, and the upper end of the annular telescopic airbag 29 is connected to the air nozzle 30 at the upper end of the front cover 4 or the rear cover 5 through a pipe. The lower end of the annular telescopic airbag 29 is connected to the air pressure gauge 31 at the lower end of the front cover 4 or the rear cover 5 through a pipe. By setting the annular telescopic airbag 29, it plays an auxiliary sealing role between the front cover 4, the rear cover 5 and the housing 1. At the same time, the degree of fixation between the housing 1 and the front and rear covers can be detected by the air pressure gauge 31. That is, when the front cover 4 and the rear cover 5 are loose, the air pressure value detected by the air pressure gauge 31 is small.

[0040] The bottom of the housing 1 is fixed with a support 32, and a level 33 is fixed in the middle of the support 32. The level 33 is used to detect the levelness of the support 32, thus preventing the device from being installed in an inclined state.

[0041] This utility model is not limited to the above-described embodiments. Anyone should know that structural changes made under the guidance of this utility model, and any technical solutions that are the same as or similar to this utility model, fall within the protection scope of this utility model. Technical aspects, shapes, and structures not described in detail in this utility model are all publicly known technologies.
