Abstract
Description
Technical Field
[0001] This utility model relates to the field of motor manufacturing technology, and in particular to a high-precision microcar motor housing. Background Technology
[0002] The motor that controls the spindle rotation operates at high speeds and requires high manufacturing precision. These spindle motors are equipped with a motor housing, which includes a cylindrical body for mounting the stator and rotor cores and a base for connecting the cylindrical body to external components. Both are usually cast as a single piece, resulting in low processing efficiency and poor overall performance.
[0003] Currently, existing high-precision spindle motor housings (such as patent number: CN213602472U) disclose a high-precision spindle motor housing comprising: a housing body, the housing body including a cylindrical inner cylinder, the outer wall of the inner cylinder having at least three positioning seats arranged in a ring array at equal intervals around its axis, the two end faces of the positioning seats respectively having end cap mounting holes; a base, the base including a support plate and a bracket, the bracket having a positioning groove for any of the positioning seats to be inserted into, the support plate having an adjusting screw hole, the adjusting screw hole having an adjusting screw whose end abuts against the positioning seat inserted into the positioning groove; and the bracket having a locking screw hole, the locking screw hole having a locking screw whose end abuts against the positioning seat inserted into the positioning groove. This spindle motor housing achieves split manufacturing, greatly improving processing efficiency, and the axis of the overall output shaft of the assembled motor can be finely adjusted up and down, making it flexible and convenient to use, with complete overall functions and strong practicality.
[0004] However, during the implementation of the above technical solution, at least the following technical problems were found: The base and the shell of the existing device are fixed by the compression of four locking screws. However, the heat dissipation groove on the positioning seat and the positioning groove on the support plate of the existing device are not equipped with a limit mechanism. When the four locking screws loosen and the base and the shell cannot be fixed together, the base and the shell may separate under the action of gravity. If the device is in an inverted state (the base is on top and the shell is on the bottom), the shell and the motor body may fall to the ground, thereby damaging the motor. Therefore, the existing device has low stability during use and may damage the motor body. Utility Model Content
[0005] (a) Technical problems to be solved
[0006] To address the shortcomings of existing technologies, this utility model provides a high-precision microcar motor housing, solving the technical problem that existing devices have low stability during use and may damage the motor body.
[0007] (II) Technical Solution
[0008] To achieve the above objectives, this utility model provides the following technical solution:
[0009] A high-precision microcar motor housing includes an inner shell and four connecting seats. The four connecting seats are distributed and fixed on the surface of the inner shell. Multiple T-shaped grooves are opened on the side of the four connecting seats away from the inner shell. Both ends of the inner shell are provided with explosion-proof mechanisms. The connecting seats are slidably connected to a base. The explosion-proof mechanism includes an end plate and an explosion-proof plate. The base includes a base plate.
[0010] Preferably, all four connecting seats have through holes, and the inner shell has a sealing groove at the end near the end plate.
[0011] Preferably, eight bolts are fixedly connected to the side of the end plate near the inner shell, and a sealing gasket is provided between the end plate and the inner shell. The sealing gasket is penetrated by the eight bolts and slidably connected to the bolts.
[0012] Preferably, the explosion-proof plate has eight through holes on its surface, the sealing gasket and the end plate are both snapped into the inside of the sealing groove, the ends of the eight plugs away from the end plate are respectively sleeved with the eight through holes, and the ends of the eight plugs that pass through the explosion-proof plate are all threaded with hexagonal nuts.
[0013] Preferably, a C-shaped seat is fixedly connected to the top surface of the substrate. Each of the two side walls of the C-shaped seat has three threaded holes. Multiple T-shaped sliders are provided on the inner bottom surface of the C-shaped seat. Hexagonal bolts are threaded into each of the six threaded holes and are pressed together with the connecting seat.
[0014] Preferably, the T-shaped slider is adapted to the substrate.
[0015] (III) Beneficial Effects
[0016] I. This application, by setting a T-shaped slider and a T-shaped groove, allows for easy installation. First, the T-shaped slider and T-shaped groove are aligned from one end of one of the connecting seats, allowing the base to slide through the T-shaped slider and T-shaped groove. Since both the T-shaped groove and the T-shaped slider are T-shaped, the base can only slide out from both ends after being connected to the connecting seat. Then, six hexagonal bolts are tightened in the threaded holes to press the connecting seat and fix the base to the connecting seat. Because the T-shaped slider and T-shaped groove have a mutual interlocking function, when the hexagonal bolts of this application loosen, the T-shaped slider and T-shaped groove will lock the base to the connecting seat, giving this application high stability and solving the problem that existing devices have low stability during use and may damage the motor body.
[0017] II. In this application, by setting up an explosion-proof mechanism, after the base and connecting seat are fixed, the sealing gasket is first placed in the sealing groove, and then the eight plugs that are fixed to the end plate are inserted into the eight through holes. The end plate is pushed into the sealing groove, at which point the eight plugs protrude from the end of the through hole away from the end plate. Then, the eight through holes of the explosion-proof plate are connected to the eight plugs, and then hexagonal nuts are screwed on the ends of the plugs to complete the installation of the explosion-proof mechanism. The explosion-proof mechanism, together with the four connecting seats, surrounds the front and rear ends and the four sides of the inner shell, so that the inner shell is protected by the explosion-proof mechanism. At the same time, the inner shell protects the motor body installed inside, so that this application has a high protection function and stability.
[0018] Third, this application, by providing a base support that is slidably connected to the connecting seat, allows the operator to adjust the position of the base support on the connecting seat as needed. The adjustable base support makes this application highly applicable. Attached Figure Description

[0025] This application provides a high-precision microcar motor housing, which effectively solves the problem that existing devices have low stability during use and may damage the motor body.
[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, the technical solution in this application embodiment effectively solves the technical problem that existing devices have low stability during use and may damage the motor body. The overall idea is as follows:
[0027] To address the problems existing in the prior art, this utility model provides a high-precision microcar motor housing, including an inner shell 1 and four connecting seats 2. The four connecting seats 2 are distributed and fixed on the surface of the inner shell 1. Multiple T-shaped grooves 201 are opened on the side of the four connecting seats 2 away from the inner shell 1. Explosion-proof mechanisms are provided at both ends of the inner shell 1. The connecting seats 2 are slidably connected to a base support 5. The explosion-proof mechanism includes an end plate 3 and an explosion-proof plate 4. The base support 5 includes a base plate 501.
[0028] Each of the four connecting seats 2 has a through hole 202, and the inner shell 1 has a sealing groove 101 at the end near the end plate 3.
[0029] Eight bolts 301 are fixedly connected to the side of the end plate 3 near the inner shell 1. A sealing gasket 7 is provided between the end plate 3 and the inner shell 1. The sealing gasket 7 is penetrated by the eight bolts 301 and is slidably connected to the bolts 301.
[0030] The explosion-proof plate 4 has eight through holes 401 on its surface. The sealing gasket 7 and the end plate 3 are both snapped into the inside of the sealing groove 101. The ends of the eight plugs 301 away from the end plate 3 are respectively sleeved with the eight through holes 401. The ends of the eight plugs 301 that pass through the explosion-proof plate 4 are all threaded with hexagonal nuts 8.
[0031] A C-shaped seat 502 is fixedly connected to the top surface of the substrate 501. Three threaded holes 504 are provided on both side walls of the C-shaped seat 502. Multiple T-shaped sliders 503 are provided on the inner bottom surface of the C-shaped seat 502. Hexagonal bolts 6 are threaded into the six threaded holes 504. The hexagonal bolts 6 are pressed together with the connecting seat 2.
[0032] The T-shaped slider 503 is adapted to the substrate 501.
[0033] By incorporating a T-shaped slider 503 and a T-shaped groove 201, during installation, the T-shaped slider 503 and T-shaped groove 201 are first joined from one end of one of the connecting seats 2, allowing the base support 5 to slide through the T-shaped slider 503 and T-shaped groove 201. Since both the T-shaped groove 201 and the T-shaped slider 503 are T-shaped, the base support 5 can only slide out from both ends after being connected to the connecting seat 2. Subsequently, six hexagonal bolts 6 are tightened in the threaded holes 504, pressing the connecting seat 2 and fixing the base support 5 to the connecting seat 2. Because the T-shaped slider 503 and T-shaped groove 201 have a mutual interlocking function, when the hexagonal bolts 6 of this application loosen, the T-shaped slider 503 and T-shaped groove 201 will lock the base support 5 to the connecting seat 2, giving this application high stability and solving the problem that existing devices have low stability during use and may damage the motor body.
[0034] Working principle:
[0035] In the first step, during installation, the T-shaped slider 503 is first connected to the T-shaped groove 201 from one end of one of the connecting seats 2, so that the base support 5 is slidably connected to the T-shaped groove 201 through the T-shaped slider 503. Since both the T-shaped groove 201 and the T-shaped slider 503 are T-shaped, after the base support 5 is connected to the connecting seat 2, it can only slide out from both ends. Then, the six hexagonal bolts 6 are tightened in the threaded holes 504 to press the connecting seat 2 and fix the base support 5 to the connecting seat 2.
[0036] The second step is to place the sealing gasket 7 into the sealing groove 101 after the base 5 is fixed to the connecting seat 2. Then, insert the eight plugs 301 that are fixed to the end plate 3 into the eight through holes 202 and push the end plate 3 into the sealing groove 101. At this time, the eight plugs 301 protrude from the end of the through hole 202 away from the end plate 3. Then, connect the eight through holes 401 of the explosion-proof plate 4 with the eight plugs 301. Finally, screw the hexagonal nut 8 on the end of the plug 301 to complete the installation of the explosion-proof mechanism.
[0037] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
