Description

Technical Field

[0001] This utility model belongs to the technical field of linear motors, and in particular relates to a linear motor base that facilitates the fixing of the stator. Background Technology

[0002] Linear motors, as drive devices that directly convert electrical energy into linear motion, are widely used in automation equipment, precision machining, rail transportation, and other fields. Among them, the stator, as one of the core components of a linear motor, directly affects the motor's operating accuracy, stability, and service life through its fixing method.

[0003] Currently, the main methods for fixing the stator of a linear motor are as follows:

[0004] Bolt fixing: The stator is fastened to the base with bolts. Although the structure is simple, the fixing process is cumbersome, and the preload of the bolts may cause the stator to deform, affecting the uniformity of the air gap and the performance of the motor.

[0005] Adhesive fixing: High-strength adhesive is used to bond the stator to the base. Although this avoids mechanical stress, the curing time is long, and it is difficult to repair or replace later. It is also prone to failure under high temperature environments.

[0006] Pressure plate fixing: Pressure plates are set on both sides of the stator and locked with bolts. Although this can reduce stator deformation, the structure is complex, occupies a lot of space, and is not conducive to compact design.

[0007] Therefore, there is a need to provide a linear motor stator fixing structure that is easy to fix and accurate in positioning. Utility Model Content

[0031] The technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are merely exemplary embodiments of this utility model, and not the only embodiments.

[0032] Example 1

[0033] like Figures 1 to 4 As shown, a linear motor base 1 for facilitating stator fixing includes a base 1 with a stator fixing structure. The stator fixing structure includes a stator seat 2, a first limiting post 3, and a second limiting post 4. The stator seat 2 is mounted on the base 1 and arranged along its length. The first limiting post 3 and the second limiting post 4 are symmetrically arranged on both sides of the stator seat 2. The first limiting post 3 has a first slot 30 on its top side facing the stator seat 2, and the second limiting post 4 has a second slot 40 on its top side facing the stator seat 2. Both the first slot 30 and the second slot 40 are made of elastic materials, such as silicone rubber, polyurethane, or thermoplastic elastomer. The first slot 30 and the second slot 40 are arranged opposite each other. The first slot 30 and the second slot 40 respectively engage the two sides of the stator 6 to fix the stator 6 on the stator base 2. When installing the stator, the stator 6 is first placed on the stator base 2 along the length of the base 1, and then the first slot 30 and the second slot 40 are respectively engaged to fix the stator 6, thereby fixing the stator 6 on the base 1 of the linear motor.

[0034] Specifically, the first slot 30 includes a first inclined surface 300, a first arc groove 301, and a first arc surface 306 connected sequentially from top to bottom. The first inclined surface 300 and the first arc surface 306 contact the upper and lower sides of one side of the stator 6, respectively. After the stator 6 is placed on the stator base 2, the first inclined surface 300 applies pressure to the upper side of one side of the stator 6 by pressing the first slot 30, and the first arc surface 306 applies pressure to the lower side of one side of the stator 6 by pressing the first slot 30. Under the combined action of the first inclined surface 300 and the first arc surface 306, the first slot 300 forms a compression and snap-fit ​​type limiting fixation on one side of the stator 6; the second slot 40 includes a second inclined surface 300, a first arc groove 301, and a first arc surface 306 connected sequentially from top to bottom. The second arc groove 401 and the second arc surface 406, the second inclined surface 400 and the second arc surface 406 respectively contact the upper and lower sides of the other side of the stator 6. Similar to the way the first slot 30 fixes one side of the stator 6, after the stator 6 is placed on the stator base 2, the second inclined surface 400 applies pressure to the upper side of the other side of the stator 6 by pressing the second slot 40, and at the same time, the second arc surface 406 applies pressure to the lower side of the other side of the stator 6 by pressing the second slot 40. Under the combined action of the second inclined surface 400 and the second arc surface 406, the second slot 40 forms a limiting fixation on the other side of the stator 6. Thus, under the combined action of the first slot 30 and the second slot 40, the stator 6 is fixed in the base 1 of the linear motor.

[0035] The first arc surface 306 and the second arc surface 406 are both protruding from the side of the stator 6. Specifically, the protruding parts of the first arc surface 306 and the second arc surface 406 abut against the corresponding side of the stator 6. In this way, the first arc surface 306 and the second arc surface 406 can better squeeze and apply pressure to the corresponding side of the stator 6, thereby strengthening the fixing effect on the stator 6.

[0036] Both the first slot 30 and the second slot 40 are made of elastic material. In actual use, the stator 6 is fixed by a compression buckle, which requires the first limiting post 3 and the second limiting post 4 to have the function of deformation. That is, the first slot 30 and the second slot 40 have the function of deformation. In this way, the first slot 30 and the second slot 40 can change the contact state with the stator 6 according to the actual contact situation between the first limiting post 3 and the second limiting post 4 and the stator 6. The elasticity of the first slot 30 allows the first inclined surface 300 and the first arc surface 306 to have deformation space, which can better apply pressure to the side of the stator 6. Similarly, the elasticity of the second slot 40 allows the second inclined surface 400 and the second arc surface 406 to have deformation space, which can better apply pressure to the side of the stator 6.

[0037] The upper surface of the stator base 2 that contacts the stator 6 is symmetrically provided with a boss 5. The boss 5 is set along the length direction of the base 1, and the protruding part of the boss 5 contacts the bottom of the stator 6. In the actual process of installing the stator 6 on the stator base 2, there may be some minor impurities entering the stator base 2. As a result, during the operation of the linear motor, the impurities will affect the operation of the linear motor, such as causing imbalance and wear. The boss 5 can avoid this situation. Even if there are minor impurities, the presence of the boss 5 can create a gap between the stator base 2 and the stator, so as not to affect the normal operation of the linear motor. Furthermore, the boss 5 makes it easy for the user to pick up the stator 6 when maintaining or replacing it, making the operation convenient. In addition, the boss 5 can distribute the load stress of the stator base 2, reduce the risk of local deformation of the stator base 2, effectively ensure the structural integrity of the stator base 2, and thus ensure the motion function of the linear motor base 1.

[0038] Example 2

[0039] Except for the following technical features, the other technical features of this embodiment are the same as those of embodiment one.

[0040] like Figures 5 to 8 As shown, the first slot 30 in this embodiment includes, from top to bottom, a first inclined surface 300, a first arc groove 301, a first inclined side 302, a first concave surface 303, a first pressing surface 304, a first groove 305, a first arc surface 306, and a first limiting groove 307 connected sequentially. The first pressing surface 304, the first groove 305, and the first arc surface 306 respectively contact the upper end face, corner, and upper side of one side of the stator 6. The bottom of the first limiting groove 307 contacts the lower side of one side of the stator 6. After the stator 6 is placed on the stator base 2, the first inclined surface 300 of the first slot 300 is pressed towards the upper end face of the stator 6, so that the first pressing surface 304 contacts the upper end face of one side of the stator 6 and provides pressure to one side of the stator 6. A downward pressure is applied to the upper end surface, causing the first groove 305 to cover the corner of one side of the stator 6 and the recessed part of the first groove 305 to abut against the corner of one side of the stator 6 and apply pressure to it facing the one side of the stator 6. The first arc surface 306 contacts the upper side of one side of the stator 6 and applies pressure to one side of the stator 6. The first limiting groove 307 contacts the lower side of one side of the stator 6 to fix it to the lower side of one side of the stator 6. Under the combined action of the first inclined surface 300, the first pressing surface 304, the first groove 305, the first arc surface 306 and the first limiting groove 307, the first slot 30 forms a pressing buckle-type limiting fixation on one side of the stator 6.

[0041] The second slot 40 includes, from top to bottom, a second inclined surface 400, a second arc groove 401, a second inclined edge 402, a second concave surface 403, a second pressing surface 404, a second groove 405, a second arc surface 406, and a second limiting groove 407 connected sequentially. The second pressing surface 404, the second groove 405, and the second arc surface 406 respectively contact the upper end face, corner, and upper side of the other side of the stator 6. The bottom of the second limiting groove 407 contacts the lower side of the other side of the stator 6. Similar to the way the first slot 30 fixes one side of the stator 6, after the stator 6 is placed on the stator base 2, the second inclined surface 400 of the second slot 40 is pressed towards the upper end face of the stator 6, so that the second pressing surface 404 contacts the upper end face of one side of the stator 6 and applies downward pressure to the upper end face of the other side of the stator 6. The second groove 405 covers the corner of the other side of the stator 6, and the recessed part of the second groove 405 abuts against the corner of the other side of the stator 6, applying pressure to it in the direction facing the other side of the stator 6. The second arc surface 406 contacts the upper side of the other side of the stator 6, applying pressure to the other side of the stator 6. The second limiting groove 407 contacts the lower side of the other side of the stator 6, fixing it to the lower side of the other side of the stator 6. Under the combined action of the second inclined surface 400, the second pressing surface 404, the second groove 405, the second arc surface 406, and the second limiting groove 407, the second locking groove 40 forms a pressing and buckling type limiting fixation on the other side of the stator 6. Thus, under the combined action of the first locking groove 30 and the second locking groove 40, the stator 6 is fixed in the base 1 of the linear motor.

[0042] Both the first pressing surface 304 and the second pressing surface 404 protrude towards the upper end face of the stator 6, and both the first arc surface 306 and the second arc surface 406 protrude towards the side of the stator 6. Specifically, the protruding parts of the first pressing surface 304 and the second pressing surface 404 respectively contact the upper end face of the stator 6 on the corresponding side. In this way, the first pressing surface 304 and the second pressing surface 404 can better apply downward pressure to the upper end face of the stator 6 on the corresponding side, thereby strengthening the fixing effect of the stator 6. At the same time, the protruding parts of the first arc surface 306 and the second arc surface 406 abut against the side of the stator 6 on the corresponding side. In this way, the first arc surface 306 and the second arc surface 406 can better squeeze and apply pressure to the side of the stator 6 on the corresponding side, thereby strengthening the fixing effect of the stator 6.

[0043] The first limiting post 3 has several first slots 30 along the length of the base 1, and the second limiting post 4 has several second slots 40 symmetrically arranged with the first slots 30 along the length of the base 1. The arrangement of multiple first slots 30 and multiple second slots 40 can improve the fixing effect of the first limiting post 3 and the second limiting post 4 on the stator 6.

[0044] Understandably, for either Embodiment 1 or Embodiment 2, if maintenance or replacement of the stator 6 is required, the elasticity of the first slot 30 and the second slot 40 can be used to pull the first limiting post 3 and the second limiting post 4 outwards, causing the first slot 30 and the second slot 40 to disengage from the stator 6, and then the stator 6 can be removed.

[0045] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
