Description

Technical Field

[0001] This utility model relates to the field of servo motor technology, and in particular to a shock-absorbing mounting structure for a servo motor. Background Technology

[0002] Existing servo motor mounting structures typically include a base, a support frame, and the mounting body. The support frame and mounting body are equipped with corresponding oblong holes or grooves. Bolts passing through the oblong holes are used to fix both components and adjust their height. When actually adjusting the motor's mounting height, the bolts must first be loosened, the mounting body moved along the extension direction of the groove or oblong hole to the target area, and then the bolts tightened to complete the fixation.

[0003] However, the existing structure lacks a temporary locking mechanism for the mounting base during height adjustment. After loosening the bolts, the mounting base is prone to displacement due to its own weight, minor external impacts, or the weight of the motor, requiring operators to continuously support it or repeatedly reposition it, increasing the complexity of the adjustment process. At the same time, the displacement will reduce the accuracy of the installation height adjustment, requiring repeated adjustments and fixing steps, thus reducing installation efficiency. Utility Model Content

[0004] The present invention aims to improve at least one technical problem in the background art.

[0005] This utility model provides a vibration damping mounting structure for a servo motor, comprising: Base The upright is mounted on the base. The upright is provided with a first sliding groove that extends in the vertical direction. The right end of the first sliding groove is connected to the outside through an opening. The upright is provided with a through first base fixing hole, which is an oblong hole. The mounting base is located on the right side of the upright frame. The mounting base has a through second base fixing hole, which communicates with the first base fixing hole to allow bolts to be inserted to fix the upright frame and the mounting base together. The mounting base also has a temporary fixing hole, which communicates with the first sliding groove through an opening. A temporary fixing component includes a cam portion, a connecting portion, and a locking portion connected in sequence. The cam portion is movably disposed in the first slide groove. The connecting portion passes through the temporary fixing hole and is rotatably connected to the temporary fixing hole. The locking portion includes a plurality of outwardly extending locking rods. The cam portion includes a short end and a long end. The length of the short end is less than the width of the first slide groove, and the length of the long end is greater than the width of the first slide groove. A movable locking sleeve is movably fitted outside the connecting part. The movable locking sleeve is located between the upright and the locking part. The movable locking sleeve is slidably connected to the mounting base. A locking groove is provided on the right side of the movable locking sleeve. The locking groove is used to cooperate with the locking rod to limit the rotation direction of the temporary fixing part. A spring, the two ends of which abut against the movable locking sleeve and the upright respectively, is used to provide elastic force to the movable locking sleeve to lock the rotation direction of the fixing member.

[0006] The beneficial effects of this utility model are as follows: by cooperating with the temporary fixing parts, the movable locking sleeve and the spring, the mounting base can be temporarily locked in the vertical direction when adjusting the installation height of the servo motor, so as to measure the installation height of the servo motor and improve the convenience and efficiency of the installation height adjustment operation.

[0007] As a sub-solution of the above technical solution, a second sliding groove is provided on the outer side of the mounting base, and a second slider is provided on the outer side of the movable locking sleeve. The second slider is slidably connected to the second sliding groove. The sliding engagement between the second slider and the second sliding groove makes the movement of the movable locking sleeve more directional, optimizes the smoothness of the engagement between the movable locking sleeve and the locking part, and further improves the stability of the temporary locking action.

[0008] As a sub-solution of the above technical solution, a limiting block is provided on the outer side of the mounting base, and the second sliding groove is formed on the limiting block on the side facing the movable locking sleeve. The limiting block provides a stable mounting base for the second sliding groove, enhances the structural load-bearing capacity of the second sliding groove, makes the sliding fit between the second slider and the second sliding groove more reliable, and ensures the stable realization of the temporary locking function.

[0009] As a sub-solution of the above technical solution, the number of locking slots is six, and the six locking slots are evenly arranged along the circumference of the movable locking sleeve. The six evenly arranged locking slots expand the lockable angle range of the temporary fixing member, improve the adaptability of the temporary locking action, and facilitate the quick finding of the locking point at different installation heights and adjustment positions.

[0010] As a sub-solution of the above technical solution, the number of locking rods is six, and the six locking rods are evenly arranged along the circumference of the temporary fixing member. The six evenly arranged locking rods correspond one-to-one with the locking slots, which improves the matching accuracy between the locking rods and the locking slots, enhances the stability of the temporary fixing member after locking, and reduces the accidental rotation of the temporary fixing member during the debugging process.

[0011] As a sub-solution of the above technical solution, the outer wall of the cam portion is covered with a silicone layer. The silicone layer on the outer wall of the cam portion can reduce the contact friction between the cam portion and the inner wall of the first slide groove, reduce the wear of both, and at the same time improve the buffering effect when the cam portion contacts the first slide groove, thus extending the service life of the temporary fixing component.

Detailed Implementation

[0014] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0015] The following is combined with Figures 1 to 4 The embodiments of this utility model are described below.

[0016] This utility model provides an embodiment of a shock-absorbing mounting bracket structure for a servo motor, including a base 1, a stand 2, a mounting bracket 3, a temporary fixing component 4, a movable locking sleeve 5, and a spring 6.

[0017] The base 1 is a plate-like structure used for fixed connection with the mounting surface, providing a stable support foundation for the entire mounting structure. The upright frame 2 is fixedly installed on the upper surface of the base 1. The upright frame 2 is a vertically extending plate shape, and a first sliding groove 21 is provided on the upright frame 2. The first sliding groove 21 extends vertically, and its right end connects to the outside through an opening 22, the width of which is the same as the width of the first sliding groove 21. The upright frame 2 also has a through first mounting hole (not shown in the figure). The first mounting hole is an oblong hole, its length extending vertically to accommodate the vertical adjustment stroke of the mounting base 3, thus changing the installation height of the motor.

[0018] Mounting base 3 is located on the right side of the upright 2, and is fitted against the right side wall of the upright 2. Mounting base 3 has a through-hole (not shown in the figure) for bolts to pass through and fix the upright 2 and mounting base 3 together. When the mounting height of the servo motor needs to be adjusted, loosening the bolts allows mounting base 3 to move vertically. After adjusting to the target height, tightening the bolts completes the fixation. Mounting base 3 also has a temporary fixing hole 32, which is a circular through hole that connects to the first slide groove 21 through opening 22. The axis of the temporary fixing hole 32 is perpendicular to the extension direction of the first slide groove 21.

[0019] The temporary fixing component 4 includes a cam portion 41, a connecting portion 42, and a locking portion 43, which are integrally formed sequentially. The cam portion 41 is movably disposed within the first slide groove 21. The connecting portion 42 passes through the temporary fixing hole 32 and is rotatably connected to the temporary fixing hole 32. A gap is provided between the connecting portion 42 and the temporary fixing hole 32 to ensure rotational flexibility. The locking portion 43 includes several outwardly extending locking rods 431, which extend radially along the connecting portion 42. The cam portion 41 has an eccentric structure, including a short end and a long end. The length of the short end is less than the width of the first slide groove 21, and the length of the long end is greater than the width of the first slide groove 21. When the long end of the cam portion 41 abuts against the inner wall of the first slide groove 21, the mounting base 3 can be temporarily locked by friction.

[0020] The movable locking sleeve 5 is movably fitted outside the connecting part 42. The movable locking sleeve 5 is located between the upright 2 and the locking part 43. The movable locking sleeve 5 is slidably connected to the mounting base 3 and can move left and right along the axis of the connecting part 42. A locking groove 51 is provided on the right side wall of the movable locking sleeve 5. The shape of the locking groove 51 is adapted to the shape of the locking rod 431 and is used to cooperate with the locking rod 431 to restrict the rotation direction of the temporary fixing part 4 and prevent the temporary fixing part 4 from rotating accidentally in the locked state.

[0021] Spring 6 is disposed between movable locking sleeve 5 and mounting base 3. Spring 6 is sleeved outside connecting part 42. One end of spring 6 abuts against the left side wall of movable locking sleeve 5 and the other end abuts against the right side wall of mounting base 3. Spring 6 is in a compressed state to provide rightward elastic force to movable locking sleeve 5, so that locking groove 51 and locking rod 431 are engaged, thereby locking the rotation direction of temporary fixing part 4.

[0022] Furthermore, in one embodiment of the present invention, a second sliding groove 311 is provided on the outer side of the mounting base 3, and a second slider 52 is provided on the outer side of the movable locking sleeve 5. The second slider 52 is slidably connected to the second sliding groove 311. The second slider 52 is integrally formed with the movable locking sleeve 5, and the second sliding groove 311 extends in the left-right direction. Through the cooperation between the second slider 52 and the second sliding groove 311, the movement of the movable locking sleeve 5 is guided, making the left-right movement of the movable locking sleeve 5 more stable.

[0023] Furthermore, in one embodiment of the present invention, a limiting block 31 is provided on the outer side of the mounting base 3, and a second sliding groove 311 is formed on the limiting block 31 on the side facing the movable locking sleeve 5. The limiting block 31 is fixed to the outer wall of the mounting base 3 by bolts. The material of the limiting block 31 is the same as that of the mounting base 3. Its setting can enhance the structural strength of the second sliding groove 311, avoid deformation of the second sliding groove 311 due to long-term sliding, and ensure the stability of the cooperation between the second slider 52 and the second sliding groove 311.

[0024] Furthermore, in one embodiment of the present invention, the number of locking slots 51 is six, and the six locking slots 51 are evenly arranged along the circumference of the movable locking sleeve 5, with an included angle of 60 degrees between two adjacent locking slots 51. The arrangement of six locking slots 51 allows the temporary fixing member 4 to be locked at multiple angles, improving the flexibility of temporary locking during debugging.

[0025] Furthermore, in one embodiment of the present invention, there are six locking rods 431, which are evenly arranged along the circumference of the temporary fixing member 4, and each of the six locking rods 431 corresponds to one of the six locking slots 51. The length of the locking rod 431 is adapted to the depth of the locking slot 51. When the locking rod 431 is embedded in the locking slot 51, it can effectively restrict the rotation of the temporary fixing member 4 and improve the stability of the lock.

[0026] Furthermore, in one embodiment of the present invention, the outer wall of the cam portion 41 is covered with a silicone layer, which is fixed to the outer wall of the cam portion 41 by adhesive bonding. The thickness of the silicone layer is 1-3mm. Its arrangement can reduce the coefficient of friction between the cam portion 41 and the inner wall of the first slide groove 21, reducing wear on both. At the same time, the silicone layer has a certain degree of elasticity, which can improve the buffering effect when the cam portion 41 abuts against the first slide groove 21, making the temporary locking more stable. In addition, the silicone layer covering the outside of the cam portion 41 can also reduce vibration between the mounting base 3 and the upright 2.

[0027] The working process of this embodiment is as follows: When adjusting the installation height of the servo motor, first loosen the bolts passing through the first and second base fixing holes, and push the mounting base 3 to move up and down to the approximate target position. At this time, push the movable locking sleeve 5 to the left, the movable locking sleeve 5 compresses the spring 6 and moves to the left, and the locking rod 431 disengages from the locking groove 51, releasing the rotation restriction on the temporary fixing member 4. Rotate the temporary fixing member 4 so that the long end of the cam part 41 faces the inner wall of the first slide groove 21 until the silicone layer on the outer side of the long end is in close contact with the inner wall of the first slide groove 21, and use friction to temporarily lock the mounting base 3. Release the movable locking sleeve 5, and the spring 6 pushes the movable locking sleeve 5 to the right under the action of elasticity, and the locking rod 431 re-embeds into the corresponding locking groove 51, restricting the rotation of the temporary fixing member 4, and completing the temporary locking operation. At this point, the installation height of the servo motor can be measured and finely adjusted. After completion, push the movable locking sleeve 5 to the left again, rotate the temporary fixing piece 4 so that the short end of the cam part 41 faces the first slide groove 21, release the temporary lock, adjust the mounting base 3 to the final target height, and tighten the bolts to complete the fixation. Of course, in order to further strengthen the connection between the mounting base 3 and the stand 2, the mounting base 3 and the stand 2 can also be welded as needed to further ensure the stability of the servo motor operation.

[0028] With the above structural design, the mounting base 3 can be temporarily locked quickly and easily during the servo motor mounting height adjustment process, reducing the positional offset of the mounting base 3 during the adjustment process, improving adjustment efficiency and accuracy, while ensuring stable cooperation among components and a long service life.
