Description

Technical Field

[0001] The present application relates to the technical field of linear motors, and in particular to a spliced ​​linear motor. Background Art

[0002] A linear motor is a transmission device that converts electrical energy directly into linear motion mechanical energy without any intermediate conversion mechanism. It can be regarded as a rotating motor cut radially and unfolded into a plane. Linear motors are also called linear motors, linear motors, linear motors, and push rod motors.

[0003] Since linear motors do not require intermediate transmission mechanisms and have high transmission efficiency, they have been widely used in industrial fields such as rail transportation, industrial control, and CNC machine tools. With the increase in the application scenarios of linear motors in various fields, the use of high-speed and long-stroke conditions has increased, and the demand for ultra-long linear motors has increased day by day. However, ultra-long motors are difficult to transport, and engineering generally relies on splicing multiple short motors.

[0004] The invention patent currently published with the publication number CN111786532A discloses a spliced ​​linear motor module, including a module body, a reference column and at least three adjustment column assemblies; the module body includes a carrier and at least two mutually spliced ​​guide rail assemblies, and the carrier is slidably arranged on the guide rail assembly; one of the guide rail assemblies is jointly supported by the reference column and at least one adjustment column assembly, and the remaining guide rail assemblies are jointly supported by at least two adjustment column assemblies, and all the guide rail assemblies are spliced ​​end to end in sequence along the extension direction of the module body; the top end of each adjustment column assembly is abutted against the bottom end of the corresponding guide rail assembly, and can be extended and retracted to drive the guide rail assembly to move vertically based on the height of the reference column.

[0005] The above-mentioned patent disclosure adopts bolts to lift the linear motor. However, when the flatness of the installation plane is poor or there are steps on the installation plane, it becomes more difficult to connect the linear motors with each other with high precision. When the linear motor is lifted by bolts, the contact between the bolts and the linear motor is point contact during the lifting process. The force borne by the bolts is relatively concentrated. When the mover in the linear motor moves and the load is transferred, the bolts are easily damaged, resulting in failure of the lifting, which in turn affects the high-precision connection between the linear motors. Summary of the invention

[0006] In order to solve the problem that a spliced ​​linear motor is difficult to connect when the installation plane conditions are poor, the present application provides a spliced ​​linear motor.

[0007] The present application provides a spliced ​​linear motor, which adopts the following technical solution: A spliced ​​linear motor comprises at least two linear motor bodies located above a mounting plane and a plurality of adjustment support modules, at least two of the linear motor bodies are respectively arranged linearly, the adjustment support modules comprise a support plate, a support body and an upper adjustment seat, two adjacent linear motor bodies are jointly arranged on the top surface of the support plate, the upper adjustment seat is arranged on the bottom surface of the support plate, the support body is arranged on the top surface of the mounting plane, a raised adjustment piece is arranged between the support body and the upper adjustment seat, and the adjustment support module is provided with a connecting component for connecting and fixing the upper adjustment seat and the support body.

[0008] By adopting the above technical solution, multiple adjustment support modules are used to support two adjacent linear motor bodies. When supporting the spliced ​​linear motor in an environment with a poor installation plane, the adjustment support body is first swung with the raised adjustment piece as the axis so that the adjustment support body is perpendicular to the installation plane. Then, the upper adjustment seat is connected and fixed to the support body through a connecting assembly. At this time, the adjustment support module supports the linear motor body through the support plate, which is beneficial to improve the stability of the spliced ​​motor support connection in an environment with poor installation plane conditions.

[0010] By adopting the above technical solution, when supporting the spliced ​​linear motor in an environment with a poor installation plane, first swing and adjust the lower adjustment seat. Since the raised adjustment piece is located between the upper adjustment seat and the lower adjustment seat, the lower adjustment seat can be swung and adjusted at any angle with the raised adjustment piece as the axis, so that the base plate is adapted to the installation plane, which is beneficial to improve the swing adjustment of the support body and the stability of adapting to the installation plane.

After the swing adjustment of the lower adjusting seat is completed, swing the adjustment screw in the strip hole, and then tighten the nut upward. At this time, the nut is pressed against the bottom surface of the lower adjusting seat, and the upper adjusting seat and the lower adjusting seat are pressed and fixed by the raised adjustment piece, which is beneficial to improve the stability of the support body after the swing adjustment and the adjustment and fixation with the upper adjusting seat.

[0013] Optionally, the adjusting device includes a lifting rod, which is slidably arranged in the supporting tube, and the top end of the lifting rod passes through the supporting tube and the lower adjustment seat in sequence. The top end of the lifting rod is universally rotatably provided with a support plate, and the support plate is supported by the raised adjusting piece. The bottom plate is provided with a driving mechanism for driving the lifting rod to rise and fall.

The lifting rod drives the raised adjustment part to rise and fall through the support plate, and the raised adjustment part then drives the upper adjustment seat to rise and fall. By separately raising and lowering and adjusting multiple adjustment support modules, the two adjacent linear motors are finally leveled, which is beneficial to improving the stability of the flat splicing of the linear motor bodies.

[0015] Optionally, the driving mechanism includes an air cylinder, which is arranged on one side of the top surface of the base plate, and the base plate is provided with an air passage for connecting the air cylinder and the support tube.

[0016] By adopting the above technical solution, when it is necessary to drive the upper adjusting seat to rise, the pressing rod is squeezed downward, the pressing rod squeezes the spring, and drives the piston to move downward. At this time, the air pressure passes through the air cylinder, the air channel and the support cylinder in sequence, and then the air pressure pushes the lifting rod upward.

[0023] Optionally, the raised adjustment member is a sphere.

[0024] By adopting the above technical solution, the spherical surface of the sphere is connected to the upper adjustment seat and the lower adjustment seat respectively, which is beneficial to increase the contact area between the raised adjustment member and the upper adjustment seat and the lower adjustment seat respectively, and improve the support and adjustment stability of the adjustment support module.

[0030] The following is combined with Figure 1-5 This application is described in further detail.

[0031] See also Figure 1 and Figure 2 , a spliced ​​linear motor, comprising a linear motor body 1, the linear motor body 1 is composed of a stator unit 2, a mover unit and a sliding member 4. In this embodiment, the number of linear motor bodies 1 is two, the two linear motor bodies 1 are respectively arranged linearly, and the two linear motor bodies 1 are spliced ​​in parallel. The bottom surface support of the splicing of the two linear motor bodies 1 is connected with a support plate 5, and three adjustment support modules 6 are installed on the bottom surface of the support plate 5. The three adjustment support modules 6 are arranged in a triangular shape on the bottom surface of the support plate 5. Among them, the adjustment support module 6 includes a support body 7 and an upper adjustment seat 8. The upper adjustment seat 8 is fixedly connected to the bottom surface of the support plate 5, the support body 7 is fixed on the mounting plane 3, and a protruding adjustment member 9 is installed between the support body 7 and the upper adjustment seat 8. The adjustment support module 6 also includes a connecting component, which is used to connect and fix the support body 7 to the upper adjustment seat 8.

[0032] The three adjustment support modules 6 use the stability of the triangle to support the two linear motor bodies 1. When the spliced ​​linear motor needs to be supported in an environment with a poor installation plane 3, the adjustment support body 7 is first swung with the raised adjustment member 9 as the axis, so that the adjustment support body 7 is vertically abutted and fixed to the installation plane 3, and then the upper adjustment seat 8 and the support body 7 are connected and fixed through the connecting assembly. At this time, the three adjustment support modules 6 support the two spliced ​​linear motor bodies 1 through the support plate 5, completing the splicing and support of the two linear motor bodies 1.

[0033] See also Figure 2 and Figure 3 In order to facilitate the support body 7 to support the spliced ​​linear motor body 1, the support body 7 includes a bottom plate 10, the top surface of the base is fixedly connected with a support cylinder 11, the top surface of the support cylinder 11 is fixedly connected with a lower adjustment seat 12, and the upper adjustment seat 8 is arranged opposite to the lower adjustment seat 12. The raised adjustment member 9 is installed between the upper adjustment seat 8 and the lower adjustment seat 12, one end of the raised adjustment member 9 is matched with the upper adjustment seat 8, and the top surface of the lower adjustment seat 12 is provided with a receiving groove 13, and the other end of the raised adjustment member 9 is matched with the lower adjustment seat 12 through the receiving groove 13.

[0034] Among them, embodiment one: See also Figure 2 The upper adjustment seat 8 is provided with an arc-shaped groove 34 adapted to the raised adjustment piece 9. When the upper adjustment seat 8 rotates in the arc-shaped groove 34 of the raised adjustment piece 9 with the upper adjustment seat 8 as the center, the raised adjustment piece 9 and the arc-shaped groove 34 are always in contact with each other to form a surface-to-surface fit. Compared with the reference document in the background technology that uses point contact between the stud and the surface, this type of fit is more evenly stressed.

[0035] Embodiment 2: See also Figure 3 The upper adjustment seat 8 is provided with a conical groove 35. During the rotation of the raised adjustment member 9 at the upper adjustment seat 8, the raised adjustment member 9 and the upper adjustment seat 8 are always in line contact. Compared with the point contact mode, this type of cooperation has less concentrated stress.

[0036] Compared with the arc-shaped groove 34 , the conical groove 35 has a lower processing cost and can be adapted to a plurality of raised adjustment members 9 with different diameters.

[0037] Specifically, in order to facilitate the connection of the upper adjustment seat 8 and the lower adjustment seat 12 after the swing adjustment, see Figure 2The connection assembly includes a screw rod 14 and a nut 15. The bottom edge of the upper adjustment seat 8 is universally hinged with a ball head 16. The number of screw rods 14 corresponds to four. The top surface of the lower adjustment seat 12 is penetrated by a bar hole 17. The number of bar holes 17 is two. The two bar holes 17 are symmetrically arranged about the vertical center axis of the lower adjustment seat 12. The fixed end of the screw rod 14 penetrates the bar hole 17, and the fixed end of the screw rod 14 is threadedly connected to the ball head 16. The number of nuts 15 corresponds to the number of screw rods 14. The nut 15 is threadedly sleeved on the screw rod 14, and the nut 15 is located below the lower adjustment seat 12.

[0038] After the lower adjustment seat 12 swings with the raised adjustment member 9 as the axis, the screw rod 14 is swung in sequence to make the screw rod 14 swing in the bar hole 17, and then the nut 15 is tightened. At this time, the nut 15 is pressed against the bottom surface of the lower adjustment seat 12, and the upper adjustment seat 8 is relatively fixed with the lower adjustment seat 12. In this way, the support body 7 adapts to the installation plane 3 while supporting the upper adjustment seat 8.

[0039] It should be noted that the diameter of the strip hole 17 is larger than the diameter of the screw rod 14, so that the screw rod 14 can swing and adjust in the strip hole 17. In addition, when connecting and fixing the upper adjustment seat 8 and the lower adjustment seat 12, the number of screw rods 14 should be selected according to the actual situation to reduce the interference of the screw rods 14 and ensure that the lower adjustment seat 12 can swing and adjust through the protruding adjustment member 9.

[0040] See also Figure 2 and Figure 4 In order to facilitate the leveling of the spliced ​​linear motor body 1, the support body 7 is equipped with an adjustment device, which is used to adjust the height of the raised adjustment member 9. The adjustment device includes a lifting rod 18, which is slidably installed in the support tube 11, and the top of the lifting rod 18 passes through the support tube 11 and the lower adjustment seat 12 in sequence, and the top of the lifting rod 18 is universally rotatably connected with a support plate 19. The support plate 19 is used to support the raised adjustment member 9, and the top surface of the support plate 19 is adapted to the outer wall surface of the raised adjustment member 9, and the bottom surface of the support plate 19 is adapted to the groove wall of the accommodating groove 13 of the lower adjustment seat 12.

[0041] In addition, the bottom plate 10 is equipped with a driving mechanism, which is used to drive the lifting rod 18 to rise and fall. The driving mechanism includes an air cylinder 20, which is fixedly connected to one side of the top surface of the bottom plate 10. An air passage 21 is provided inside the bottom plate 10, and the air passage 21 is used to connect the air cylinder 20 and the support cylinder 11. A piston 22 is slidably installed in the air cylinder 20, and a pressing rod 23 is fixedly connected to the top surface of the piston 22, and the top end of the pressing rod 23 extends above the air cylinder 20. A spring 24 is sleeved on the side wall of the pressing rod 23, one end of the spring 24 is fixedly connected to the side wall of the pressing rod 23, and the other end of the spring 24 is fixedly connected to the top surface of the air cylinder 20.

[0042] When the pressing rod 23 is pressed downward, the pressing rod 23 drives the piston 22 to move downward, and the pressing rod 23 squeezes the spring 24. The piston 22 squeezes the airflow downward, and the airflow passes through the support cylinder 11, the air passage 21 and the support cylinder 11 in sequence, and then pushes the lifting rod 18 upward. At this time, the lifting rod 18 drives the raised adjustment member 9 to move upward, and the raised adjustment member 9 drives the upper adjustment seat 8 to move upward, thereby realizing the leveling of the spliced ​​linear motor body 1.

[0043] See also Figure 2 In order to block the flow of air pressure in the support tube 11 and fix the lifting rod 18 at the current lifting position, the support tube 11 is equipped with a blocking assembly, which includes a blocking seat 25 and a blocking ball 26. The blocking seat 25 is fixedly connected to the inner wall of the support tube 11, and a blocking port 27 is penetrated through the bottom surface of the blocking seat 25. The blocking ball 26 is movably installed in the blocking seat 25, and the blocking ball 26 is plugged into the blocking port 27.

[0044] In addition, in order to improve the stability of the blocking ball 26 in blocking or opening the blocking port 27, the blocking seat 25 includes an inverted cone 28, which is fixedly connected to the inner wall of the support tube 11, the inside of the inverted cone 28 is through-set, and the blocking port 27 is opened on the bottom surface of the inverted cone 28. The blocking ball 26 is movably installed in the inverted cone 28, and a blocking rod 29 is fixedly connected to the top surface of the inverted cone 28. The blocking rod 29 is tilted in a direction close to the vertical axis of the inverted cone 28. There are multiple blocking rods 29, and the multiple blocking rods 29 together block the blocking ball 26 to prevent the blocking ball 26 from escaping from the inverted cone 28.

[0045] When the airflow is lifted upward along the support tube 11, the airflow drives the blocking ball 26 to move upward, at which time the blocking ball 26 is separated from the blocking port 27, and the airflow flows toward the lifting rod 18 through the blocking port 27, so that the airflow drives the lifting rod 18 to rise. When the airflow is stopped, the blocking ball 26 is reset and inserted into the blocking port 27 under the action of its own gravity. At this time, the airflow between the lifting rod 18 and the blocking seat 25 maintains the air pressure unchanged, so that the lifting rod 18 maintains the current lifting height.

[0046] It should be noted that see Figure 2 The side wall of the support tube 11 is fixedly connected with an exhaust pipe 30, the height of the exhaust pipe 30 is located above the plug seat 25, and the exhaust pipe 30 is fixedly connected with an air valve 31. When the jacking rod 18 needs to be lowered, the air valve 31 is opened to allow the air flow in the support tube 11 to circulate with the outside, so that the jacking rod 18 is lowered.

[0047] In addition, the support tube 11 can also be configured as a transparent side wall and provided with a scale, so as to facilitate regulating the lifting height of the lifting rod 18 through the scale.

[0048] It is worth noting that see Figure 2An air flow gap 32 is reserved between the peripheral side of the piston 22 and the inner wall of the cylinder 20 , and air holes 33 are evenly distributed on the top surface of the cylinder 20 .

[0049] When the piston 22 is stretched upward, the external airflow flows into the air cylinder 20 through the air holes 33 and the airflow gap 32 in sequence. When the piston 22 is pressed downward, the piston 22 further presses the airflow in the air cylinder 20 into the support tube 11.

[0050] See also Figure 2 The raised adjusting member 9 is a sphere, the upper adjusting seat 8 is connected to the spherical surface of the sphere through the arc groove 34, and the lower adjusting seat 12 is connected to the spherical surface of the sphere through the receiving groove 13. Under the action of the sphere, it is beneficial to ensure the stability of the swing adjustment of the lower adjusting seat 12 with the sphere as the axis.

[0051] Similarly, see Figure 5 The raised adjustment member 9 can also be a hemispherical body, and the plane of the hemispherical body is fixed to the bottom surface of the upper adjustment seat 8, or plugged into the top surface of the lower adjustment seat 12.

[0052] Working principle of a spliced ​​linear motor: When it is necessary to support the spliced ​​linear motor in an environment with a poor installation plane 3, first support the support plate 5 at the joint of the bottom surfaces of the two linear motor bodies 1, and then pre-place the positions of the three adjustment support modules 6 so that the three adjustment support modules 6 are supported in a triangular manner. Then drive the support tube 11 to swing, and the support tube 11 drives the lower adjustment seat 12 to swing with the raised adjustment member 9 as the axis until the bottom plate 10 completely abuts against the installation plane 3. Then, the fixed end of the screw rod 14 passes through the bar hole 17 and is threadedly connected to the ball head 16, and finally the nut 15 is tightened. At this time, the nut 15 is pressed against the bottom surface of the lower adjustment seat 12, and the support body 7 is fixedly connected to the upper adjustment seat 8 through the raised adjustment member 9. The spliced ​​linear motor is supported in an environment with a poor installation plane 3.

[0053] When the three adjustment support modules 6 need to be leveled, first loosen the nut 15, then press the pressing rod 23 downward, the pressing rod 23 squeezes the spring 24, and drives the piston 22 to move downward, the piston 22 drives the airflow to squeeze into the support tube 11, the airflow drives the blocking ball 26 to separate from the blocking port 27, the airflow drives the lifting rod 18 to lift upward after passing through the blocking seat 25, and the lifting rod 18 drives the upper adjustment seat 8 to move upward through the protruding adjustment member 9. Repeat this process, and finally the three adjustment support modules 6 are leveled.

[0054] In summary, under the action of the raised adjustment member 9, the adjustment support module 6 supports the linear motor body 1 through the support plate 5, which is beneficial to improve the stability of the spliced ​​motor support connection in an environment where the installation plane 3 is in poor condition.

[0055] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
