Description

Technical Field

[0001] This utility model belongs to the technical field of linear motors, and in particular relates to a linear motor module with a bearing-assisted guiding structure. Background Technology

[0002] Linear motor modules are widely used in industrial automation due to their advantages such as high speed, high acceleration, and high positioning accuracy. However, linear motor modules still have the following problems under high-speed motion or high-load conditions: the mover is not stable when sliding within the base of the linear motor module, and is prone to positional deviation, which affects the working performance of the linear motor module and is not conducive to high-speed or high-load motion.

[0003] Therefore, there is a need to provide a linear motor module with a bearing-assisted guiding structure that can solve the above-mentioned technical problems. Utility Model Content

[0004] The main purpose of this utility model is to provide a linear motor module with a bearing-assisted guiding structure to address the shortcomings of the existing technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A linear motor module with a bearing-assisted guiding structure includes a base, a stator, a mover, and a movable seat. The stator is mounted on the base, the mover is mounted on the stator, and the movable seat is mounted on the mover. Bearing-assisted guiding structures are fixedly mounted on both sides of the mover. Each bearing-assisted guiding structure includes a bearing connecting block. A first bearing and a second bearing are mounted on the front and rear ends of the bearing connecting block. The first bearing and the second bearing are rotatably connected to the bearing connecting block and are arranged at a 90° angle to each other. The inner walls of both sides of the base are provided with sliding grooves to allow the first bearing and the second bearing to slide along the sliding grooves within the base.

[0006] Preferably, the bearing connecting block is a right pentagonal prism structure, and the two bottom surfaces of the bearing connecting block are convex pentagons. The convex pentagon includes a bottom edge, a first side edge, a second side edge, a first inclined edge, and a second inclined edge. The bottom edge contacts the side end of the moving part. The first side edge is close to the bottom of the base. The second side edge is arranged opposite to the first side edge with respect to the axis of the convex pentagon. One end of the first inclined edge is connected to the first side edge, and the other end of the first inclined edge is connected to one end of the second inclined edge. The other end of the second inclined edge is connected to the second side edge. The first inclined edge is close to the bottom of the base. The second inclined edge is arranged opposite to the first inclined edge with respect to the axis of the convex pentagon. The first inclined edge and the second inclined edge are arranged at 90°.

[0007] Preferably, the first inclined side is provided with a first screw hole, and the second inclined side is provided with a second screw hole, and the first screw hole and the second screw hole are arranged at a 90° angle to each other.

[0008] Preferably, the first bearing has a first screw, the second bearing has a second screw, the first screw and the first screw hole cooperate with each other to enable the first bearing to be rotatably connected to the first inclined side, and the second screw and the second screw hole cooperate with each other to enable the second bearing to be rotatably connected to the second inclined side.

[0009] Preferably, the slide groove is K-shaped, and the slide groove includes a lower sliding surface and an upper sliding surface. The lower sliding surface is close to the bottom of the base, and the upper sliding surface is arranged opposite to the lower sliding surface with respect to the axis of the slide groove. The upper sliding surface and the lower sliding surface are arranged at 90°. The lower sliding surface contacts the sliding end of the first bearing, and the upper sliding surface contacts the sliding end of the second bearing.

[0010] Preferably, the slide groove is provided with a buffer groove that is consistent with its path. One end of the buffer groove is connected to the lower sliding surface, and the other end of the buffer groove is connected to the upper sliding surface.

[0011] Preferably, the side wall of the movable seat is provided with an outlet pipe for connecting the moving element.

[0012] Compared with the prior art, the present invention will have at least the following beneficial effects: The bearing-assisted guiding structure assists the mover in sliding within the base, improving the performance of the linear motor module. The first and second bearings are positioned at a 90° angle to each other, allowing them to slide within the groove without interference. Furthermore, this 90° angle arrangement ensures smooth sliding of the mover within the base.

[0013] The first bearing has a first screw, and the second bearing has a second screw. When the first screw and the first screw hole are engaged, the first bearing and the first inclined side are rotatably connected. When the second screw and the second screw hole are engaged, the second bearing and the second inclined side are rotatably connected.

[0014] While the sliding end of the first bearing contacts the lower sliding surface, the sliding end of the second bearing contacts the upper sliding surface. In this way, during operation, the first bearing sliding along the lower sliding surface will not interfere with the second bearing sliding along the upper sliding surface, and similarly, the second bearing sliding along the upper sliding surface will not interfere with the first bearing sliding along the lower sliding surface. Therefore, it can be ensured that the first bearing and the second bearing slide simultaneously in the slide groove. The 90° setting of the upper and lower sliding surfaces ensures that the first bearing and the second bearing always maintain a 90° cross-shaped setting when sliding along the slide groove.

[0017] 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.

[0018] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationships based on the directional or positional relationships shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0019] like Figures 1 to 10 As shown, a linear motor module with a bearing-assisted guiding structure includes a base 1, a stator 2, a mover 3, and a movable seat 11. The stator 2 is mounted on the base 1, the mover 3 is mounted on the stator 2, and the movable seat 11 is mounted on the mover 3. The movable seat 11 is used to support the components that require the use of the linear motor module in this embodiment. Bearing-assisted guiding structures are fixedly installed on both sides of the mover 3. The bearing-assisted guiding structures are used to assist the mover 3 in sliding smoothly within the base 1, thereby improving the performance of the linear motor module. Specifically: The bearing auxiliary guide structure includes a bearing connecting block 4. A first bearing 5 and a second bearing 6 are installed at both the front and rear ends of the bearing connecting block 4, and the first bearing 5 and the second bearing 6 are rotatably connected to the bearing connecting block 4. The first bearing 5 and the second bearing 6 are arranged at a 90° angle. The inner walls on both sides of the base 1 are provided with sliding grooves 9 so that the first bearing 5 and the second bearing 6 can slide along the sliding grooves 9 in the base 1. Specifically, the sliding ends of the first bearing 5 and the second bearing 6 are in contact with the sliding grooves 9. The 90° angle arrangement of the first bearing 5 and the second bearing 6 can reduce the frictional force of the first bearing 5 and the second bearing 6 in contact with the sliding grooves 9, thereby reducing the frictional force of the moving part 3 connected to the bearing connecting block 4 sliding along the base 1. The 90° angle arrangement of the first bearing 5 and the second bearing 6 can ensure that the moving part 3 slides smoothly in the base 1.

[0020] Furthermore, the bearing connecting block 4 is a right pentagonal prism structure, and the two bottom surfaces of the bearing connecting block 4 are convex pentagons, that is, the two end cross-sections of the bearing connecting block 4 are convex pentagons. The convex pentagon includes a base 400, a first side 401, a second side 402, a first inclined side 403, and a second inclined side 404. The base 400 contacts the side end of the mover 3. The first side 401 is close to the bottom of the base 1. The second side 402 is positioned opposite to the first side 401 along the axis of the convex pentagon. The first inclined side 403... One end is connected to the first side 401, the other end of the first inclined side 403 is connected to one end of the second inclined side 404, and the other end of the second inclined side 404 is connected to the second side 402. The first inclined side 403 is close to the bottom of the base 1, and the second inclined side 404 and the first inclined side 403 are arranged opposite each other with the axis of the convex pentagon. The first inclined side 403 and the second inclined side 404 are arranged at 90°. This arrangement facilitates the rotational connection between the first bearing 5 and the first inclined side 403, and the rotational connection between the second bearing 6 and the second inclined side 404.

[0021] Furthermore, to achieve a rotatable connection between the first bearing 5 and the first inclined side 403, a first screw hole 405 is provided on the first inclined side 403. To achieve a rotatable connection between the second bearing 6 and the second inclined side 404, a second screw hole 406 is provided on the second inclined side 404. To ensure that the first bearing 5 and the second bearing 6 are rotatably connected after the first bearing 5 and the first inclined side 403 are rotatably connected, and that the first bearing 5 and the second bearing 6 are rotatably connected after the second bearing 6 is rotatably connected, the first screw hole 405 and the second screw hole 406 are rotatably connected at 90° to each other.

[0022] The first bearing 5 has a first screw 7, and the second bearing 6 has a second screw 8. When the first screw 7 is engaged with the first screw hole 405, the first bearing 5 is rotatably connected with the first inclined side 403. When the second screw 8 is engaged with the second screw hole 406, the second bearing 6 is rotatably connected with the second inclined side 404.

[0023] Furthermore, the slide groove 9 is K-shaped. Specifically, the slide groove 9 includes a lower sliding surface 900 and an upper sliding surface 901. The lower sliding surface 900 is located near the bottom of the base 1, and the upper sliding surface 901 is positioned opposite the lower sliding surface 900 along the axis of the slide groove 9, forming a 90° angle with the lower sliding surface 900. The lower sliding surface 900 contacts the sliding end of the first bearing 5, and the upper sliding surface 901 contacts the sliding end of the second bearing 6. Through the above arrangement, while the sliding end of the first bearing 5 contacts the lower sliding surface 900, the sliding end of the second bearing 6 contacts the upper sliding surface 901. The sliding surfaces 901 are in contact, so that when the first bearing 5 slides along the lower sliding surface 900 during operation, it will not interfere with the second bearing 6 sliding along the upper sliding surface 901. Similarly, when the second bearing 6 slides along the upper sliding surface 901, it will not interfere with the first bearing 5 sliding along the lower sliding surface 900. Therefore, it can be ensured that the first bearing 5 and the second bearing 6 slide simultaneously in the slide groove 9. The 90° setting of the upper sliding surface 901 and the lower sliding surface 900 ensures that the first bearing 5 and the second bearing 6 always maintain a 90° cross-shaped setting when sliding along the slide groove 9.

[0024] To further ensure that the first bearing 5 does not contact the upper sliding surface 901 when sliding along the lower sliding surface 900, and the second bearing 6 does not contact the lower sliding surface 900 when sliding along the upper sliding surface 901, a buffer groove 10 is provided in the slide groove 9 with the same path. One end of the buffer groove 10 is connected to the lower sliding surface 900, and the other end of the buffer groove 10 is connected to the upper sliding surface 901. In this way, the first bearing 5 and the second bearing 6 will not interfere with each other when sliding in the slide groove 9.

[0025] The side wall of the movable base 11 is provided with a cable outlet pipe 12 for connecting the mover 3. The mover 3 can place the wire along the cable outlet pipe 12, which can save the longitudinal space of the mover 3, save the volume of the linear motor module, and meet the design requirements of equipment miniaturization.

[0026] 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.
