Description

Technical Field

[0001] This utility model relates to the field of permanent magnet speed regulator technology, specifically a highly stable and easily adjustable mobile base. Background Technology

[0002] When a motor is in operation, it is often mounted on a movable base to facilitate horizontal movement and coordination with mechanical devices such as speed controllers. Typically, existing movable bases use a sliding structure—a slider and a guide rail—along with a drive mechanism to adjust the base's displacement. However, existing guide rails and sliders are not installed at the corners of the movable base. During motor operation, the corners of the movable base lack fixation, making them prone to vibration, reducing the stability of the movable base and affecting motor performance. Furthermore, because the movable base needs to move horizontally, and the motor itself is quite heavy, adjusting the movable base becomes extremely inconvenient when the sliding and drive mechanisms lack lubrication, potentially impacting production schedules in severe cases. Utility Model Content

[0003] The technical problem this utility model aims to solve is that existing mobile bases, due to the position of the sliding structure, cause instability in the corner areas, affecting the normal operation of the device. Furthermore, a lack of lubricating grease in the sliding structure affects the adjustment of the mobile base. To address these problems, a highly stable and easily adjustable mobile base is proposed, comprising a base moving part, a base fixing part, a locking component, a slider mechanism, and a drive mechanism. The slider mechanism has four sets, each located at one of the four corners of the base fixing part. The slider mechanisms are connected to the base moving part. A locking component for fixing and installing the motor is located in the middle of each set of slider mechanisms. The drive mechanism is located on the base fixing part and connected to the base moving part. The drive mechanism has a grease nipple for adding lubricating grease, which extends out of the base moving part.

[0004] The technical solution of this utility model, by setting four sets of slider mechanisms, are respectively located at the corners of the base moving part. When the motor is working, since there are connections at the corners of the base moving part, the base moving part is not prone to vibration, which can improve the stability of motor installation and operation. At the same time, each set of slider mechanisms is equipped with three linear guides. The linear guides are standard parts with small errors. Therefore, the three linear guides can ensure the flatness of one corner of the base moving part. Combined with the other three sets of slider mechanisms, the entire base moving part can be kept flat. By setting grease nipples, a first grease check port and a second grease check port, the grease nipples facilitate the addition of lubricating grease to the drive mechanism, while the first grease check port and the second grease check port facilitate the addition of lubricating grease to all slider mechanisms. Therefore, all moving mechanisms can be lubricated to ensure smooth sliding and facilitate the horizontal movement of the motor.

[0005] In a preferred embodiment of the present invention, the locking element is a screw and a nut; the surface of the movable part of the base is provided with a through hole for the screw to pass through, the diameter of which is larger than the diameter of the screw; the side wall of the fixed part of the base is provided with an installation opening for tightening the locking element. The screw and nut cooperate to firmly fix the motor on the movable part of the base. The through hole diameter is larger than the screw diameter, which facilitates fine adjustment of the motor shaft during alignment. The installation opening facilitates tightening the screw and nut after fine adjustment to fix the motor.

[0006] In a preferred embodiment of the present invention, each set of slider mechanisms includes three linear guide rails, each linear guide rail including a slider and a guide rail. The sliders of two linear guide rails are connected to the base moving part, and the guide rails are connected to the base fixing part; the slider of the other linear guide rail is connected to the base fixing part, and the guide rails are connected to the base moving part. The three linear guide rails can ensure that the corners are fixed, flat and stable, and since three linear guide rails are provided at each of the four corners, the base is more stable.

[0007] In a preferred embodiment of the present invention, the upper surface of the base moving part is provided with a first oil inspection port for cooperating with the slider, and the side wall of the base fixing part is provided with a second oil inspection port for cooperating with the slider. The first oil inspection port and the second oil inspection port cooperate with each other, so that lubricating oil can be added to all the sliders, thus ensuring smooth displacement of the base moving part.

[0008] In a preferred embodiment of the present invention, the side wall of the fixed part of the base is provided with scale lines, and the side wall of the movable part of the base is provided with a pointer that cooperates with the scale lines. By cooperating with the scale lines and the pointer, the displacement distance of the movable part of the base can be observed.

[0009] In a preferred embodiment of the present invention, the driving mechanism includes a connecting flange, a rotating shaft, a fixed shaft seat, a coupling, a lead screw, a moving block, and a positioning shaft seat. The rotating shaft passes through the fixed shaft seat, which is located inside the base fixing part. One end of the rotating shaft extends out of the base fixing part and is connected to an external power mechanism through the connecting flange. The other end of the rotating shaft is connected to one end of the lead screw through the coupling. The lead screw passes through the positioning shaft seat. The moving block is threadedly connected to the lead screw and connected to the base moving part. The rotating shaft drives the lead screw to rotate, allowing the moving block to move on the lead screw, thereby causing the base moving part to slide.

[0010] In a preferred embodiment of the present invention, the movable block comprises a main body, mounting bolts, a baffle, and a nut block. The top of the main body is connected to the movable part of the base via mounting bolts. The main body has a hollow structure with holes at both ends. The nut block is fixed on one side of the holes and is threadedly connected to a lead screw. The baffle is fixed on the other side of the holes, and the center of the baffle has a circular hole through which the lead screw passes. The grease nipple is located at the upper end of the main body and communicates with the cavity. Lubricating grease can be injected into the interior of the main body of the movable block through the grease nipple. When the movable block moves along the lead screw, it can be lubricated, making the movement smooth.

[0011] In a preferred embodiment of the present invention, the upper surface of the movable part of the base is provided with an inspection port for easy replacement of the coupling. The inspection port facilitates direct replacement of the coupling without disassembling the entire base, making the operation convenient.

[0012] In a preferred embodiment of the present invention, the highly stable and easily adjustable mobile base further includes multiple fasteners for temporarily fixing the mobile part and the fixed part of the base. The fasteners are used to connect the mobile part and the fixed part of the base, facilitating transportation or use as a fixed base.

[0013] In a preferred embodiment of the present invention, the surface of the base moving part is provided with a plurality of adjusting components for fine-tuning the position of the motor. The adjusting components are opposite to the four sides of the motor, which facilitates fine-tuning of the motor position in the horizontal direction.

[0014] The advantages of this utility model compared with the prior art are: The technical solution of this utility model, by setting four sets of slider mechanisms, are respectively located at the corners of the base moving part. When the motor is working, since there are connections at the corners of the base moving part, the base moving part is not prone to vibration, which can improve the stability of motor installation and operation. At the same time, each set of slider mechanisms is equipped with three linear guides. The linear guides are standard parts with small errors. Therefore, the three linear guides can ensure the flatness of one corner of the base moving part. Combined with the other three sets of slider mechanisms, the entire base moving part can be kept flat. By setting grease nipples, a first grease check port and a second grease check port, the grease nipples facilitate the addition of lubricating grease to the drive mechanism, while the first grease check port and the second grease check port facilitate the addition of lubricating grease to all slider mechanisms. Therefore, all moving mechanisms can be lubricated to ensure smooth sliding and facilitate the horizontal movement of the motor. Attached Figure Description

Detailed Implementation

[0016] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model will be described in detail below. Example 1

[0017] like Figure 1-4 As shown, this utility model is a highly stable and easily adjustable mobile base, including a base moving part 1, a base fixing part 2, a locking part 3, a slider mechanism 4, and a driving mechanism 5.

[0018] The base moving part 1 is plate-shaped, and the base fixing part 2 is dish-shaped. The base moving part 1 is located above the base fixing part 2, and the base moving part 1 can slide in the horizontal direction. The motor is installed on the upper surface of the base moving part 1 and is fixed by the locking member 3.

[0019] The locking component 3 consists of a screw and a nut. The screw passes through the base moving part 1 and the motor base in sequence, and then the nut and the screw are locked together by threads to connect the motor to the base moving part 1.

[0020] The surface of the base moving part 1 is provided with a through hole 11 for the screw to pass through. The motor base is also provided with a hole of the same specification, so the screw can pass through. Since the diameter of the screw is slightly smaller than the diameter of the through hole 11, the position of the motor can be slightly adjusted so that the motor shaft can be aligned and connected to the load shaft or coupler.

[0021] Slight motor adjustments are achieved through adjusting components 7, which are fixedly mounted on the base moving part 1. There are multiple adjusting components 7, located on the four sides of the motor base, opposite to it. For example, adjusting component 7 includes a fixed plate and an adjusting top block. The fixed plate is fixedly connected to the base moving part 1, and the adjusting top block is threadedly connected to the fixed plate and is opposite to the motor base. By rotating the adjusting top block, it can be moved to fit against the motor base and move slightly, thus achieving fine adjustment of the motor.

[0022] After fine-tuning, the motor is fixed by the locking member 3. It should be noted that when the locking member 3 is fixed, gaskets need to be provided on both sides that fit the base moving part 1 and the motor base to avoid the through hole 11 being too large, which is not conducive to the fixing and locking of the locking member.

[0023] Meanwhile, an installation opening 21 is provided on the side wall of the base fixing part 2. The installation opening 21 is close to the position of the locking member 3. Through the installation opening 21, it is convenient to tighten the locking member 21 to firmly fix the motor.

[0024] There are four sets of slider mechanisms 4, and each set of slider mechanisms 4 is located at the corners of the base moving part 1 respectively.

[0025] Each set of slider mechanisms 4 includes three linear guides. The linear guides belong to the prior art and are standard parts with small errors. Therefore, three linear guides in each set can ensure that one corner of the base moving part 1 remains flat. Cooperating with the other three sets of linear guides can make the entire base moving part 1 remain flat.

[0026] Each linear guide includes two parts: a slider and a guide rail. The slider is connected to the base moving part 1 by screws, and the guide rail is connected to the base fixing part 2 by screws. And the three linear guides in each set are distributed in a "pin" shape, and the through hole 11 is located in the middle of the three linear guides.

[0027] The installation operations of the other three sets of slider mechanisms 4 are the same as the above.

[0028] Of course, for the consideration of saving space, one of the three linear guides needs to be installed reversely, that is, the slider of this linear guide is connected to the base fixing part 2, and the guide rail is connected to the base moving part 1, and this linear guide is close to the two side walls of the base fixing part 2 at the same time.

[0029] Each slider is provided with a lubricating grease filling port. For the three linear guides in each set of slider mechanisms 4, the sliders of two of them are connected to the base moving part 1, and two first oil inspection ports 12 are provided at the corresponding positions on the surface of the base moving part 1. The slider of the other one is connected to the base fixing part 2, and a second oil inspection port 22 is provided at the corresponding position on the side wall of the base fixing part 2. Through the first oil inspection port 12 and the second oil inspection port 22, lubricating grease can be added to the sliders in sequence without disassembling and separating the base moving part 1 and the base fixing part 2, and the operation is simpler.

[0030] The base moving part 1 and the base fixing part 2 can move horizontally through the cooperation of the slider mechanisms 4. A scale line is provided on the side wall of the base fixing part 2, and a pointer cooperating with the scale line is provided on the side wall of the base moving part 1. When moving, the distance of the displacement of the base moving part 1 can be obtained through the pointer and the scale line.

[0031] This device also includes multiple fixing components 6, each consisting of a bonding plate and multiple fixing screws. The fixing components 6 simultaneously bond to both the base moving part 1 and the base fixed part 2. The screws then pass through the bonding plate and fix both the base moving part 1 and the base fixed part 2, securing them in place. The base moving part 1 and the base fixed part 2 cannot move relative to each other. This configuration applies to transportation or situations where the motor is directly connected to the load, and the motor does not require adjustment; in these cases, the base is a fixed base. Under normal circumstances, however, the base moving part 1 needs to be moved, and the fixing components 6 are removed.

[0032] The drive mechanism 5 provides power so that the base moving part 1 can be displaced.

[0033] The drive mechanism 5 includes a connecting flange 51, a rotating shaft 52, a fixed shaft seat 53, a coupling 54, a lead screw 55, a moving block 56, and a positioning shaft seat 57.

[0034] The rotating shaft 52 is installed in the base fixing part 2 through the fixed shaft seat 53. One end of the rotating shaft 52 extends out of the base fixing part 2 and is connected to the connecting flange 51. The connecting flange 51 can be connected to an external power mechanism, such as a motor, so that the rotating shaft 52 can be driven to rotate through the power source. The other end of the rotating shaft 52 is connected to the lead screw 55 through the coupling 54.

[0035] The lead screw 55 is supported by two positioning shaft seats 57, which connect it to the base fixing part 2. The rotating shaft 52 can drive the lead screw 55 to rotate together. The moving block 56 is threadedly connected to the lead screw 55 and is located between the two positioning shaft seats 57. The moving block 56 is connected to the base moving part 1.

[0036] The movable block 56 includes a main body 561, mounting bolts 562, grease nipple 563, baffle 564, and nut block 565.

[0037] The top of the main body 561 is connected to the base moving part 1 by mounting bolts 562. The main body 561 has a hollow structure with holes at both ends. Nut block 565 is fixed on one side of the hole and is threadedly connected to lead screw 55. Baffle 564 is fixed on the other side of the hole. The center of baffle 564 has a circular hole through which lead screw 55 passes. The grease nipple 563 is located at the upper end of the main body 561 and connects to the cavity. Lubricating grease can be added to the cavity of the main body 561 through the grease nipple 563.

[0038] An inspection port is provided on the upper surface of the base moving part 1, through which the coupling can be directly replaced, avoiding disassembly and reducing the difficulty of operation.

[0039] The base moving part 1 and the base fixing part 2 are also provided with mechanical limiting structures to prevent the base moving part 1 from displacing excessively. The mechanical limiting structure includes a limiting block or two stops. The limiting block is fixedly connected to the base moving part 1 by screws, and the stops are fixedly connected to the base fixing part 2 by screws. The limiting block is located between the two stops. Through the constraint of the two stops, the displacement range of the limiting block is limited, that is, the movement range of the base moving part 1 is limited.

[0040] The above embodiments are only for illustrating the technical concept of this utility model and should not be used to limit the protection scope of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the protection scope of this utility model.
