Description

Technical Field

[0001] This invention relates to the field of automated assembly technology, specifically to an electromagnet push rod installation and adjustment device and an electromagnet push rod installation and adjustment method. Background Technology

[0002] Electromagnetic pilot valves are mainly used in hydraulic industry control systems. The push rod in the electromagnet of the electromagnetic pilot valve has very high precision requirements during the assembly process, especially the extension length and coaxiality after assembly, which directly affect the product quality of the electromagnet.

[0003] The existing method involves manual assembly. Operators first position the armature and the guide cylinder inside the electromagnet housing, then screw the push rod into the threaded hole of the armature. Finally, a dial indicator is used to check the extension length of the push rod, and adjustments are made continuously to ensure the extension length meets the acceptable standard. Manual assembly and adjustment result in low accuracy of the electromagnet push rod extension length, affecting the quality of the electromagnet and electromagnetic pilot valve. Furthermore, the measurement and adjustment process is cumbersome, leading to long assembly cycles and low production efficiency. Summary of the Invention

[0004] The present invention aims to at least partially solve one of the technical problems in the related art.

[0005] Therefore, this invention provides an electromagnet push rod installation and adjustment device, which can install the push rod of the electromagnet and adjust the extension length of the push rod.

[0006] This invention also proposes a method for installing and adjusting an electromagnet push rod.

[0007] The electromagnet push rod mounting and adjusting device of this invention includes a frame, a first clamping unit, a measuring unit, a sleeve, and a tightening unit.

[0008] The first clamping unit is disposed on the frame, and the first clamping unit is used to clamp the electromagnet to position the electromagnet;

[0009] The measuring unit is used to detect the displacement of the push rod relative to the electromagnet, and to send a displacement signal when the displacement reaches a set range;

[0010] The sleeve is provided with a positioning groove, and the positioning groove is provided with a positioning surface and an anti-rotation surface. The positioning surface is used to position the push rod axially, and the anti-rotation surface is used to prevent the push rod from rotating. The push rod has a first position and a second position in the positioning groove. In the first position, the lower end face of the push rod is in contact with the positioning surface and the push rod is rotatable relative to the sleeve. In the second position, the outer periphery of the push rod is anti-rotated with the anti-rotation surface.

[0011] The tightening unit is connected to the sleeve, and the tightening unit is used to drive the sleeve to rotate and move along the axial direction of the push rod. During the rotation of the sleeve, the push rod can move from the first position to the second position. When the push rod is in the second position, it is driven to rotate by the tightening unit to screw into the electromagnet.

[0012] The tightening unit can receive the displacement signal from the measuring unit and stop driving the sleeve to rotate after receiving the displacement signal.

[0013] In the electromagnet push rod installation and adjustment device of this invention, the sleeve is provided with a positioning groove, and the push rod has a first position and a second position within the positioning groove. In the first position, the lower end face of the push rod contacts the positioning surface, facilitating the initial mounting of the electromagnet onto the outer circumference of the push rod. In the first position, the push rod can rotate relative to the sleeve. During the rotation of the sleeve driven by the tightening unit, the push rod can move from the first position to the second position, achieving a mating process between the push rod and the sleeve. Due to this mating process, there is no need to manually control the placement angle of the push rod when placing it in the positioning groove. In the second position, the outer circumference of the push rod engages with the anti-rotation surface, allowing the tightening unit to drive the push rod to rotate via the sleeve to screw in the electromagnet.

[0014] During the screwing of the push rod into the electromagnet, the measuring unit detects the displacement of the push rod relative to the electromagnet and sends the displacement signal to the tightening unit. Once the tightening unit receives the displacement signal, it stops driving the sleeve to rotate. This process ensures that the extension length of the push rod is within the set range, and the entire installation and adjustment process of the push rod can be completed automatically, saving manpower and improving production efficiency.

[0015] In some embodiments, the tightening unit includes a lifting platform, a driving component, a screwing component, and an elastic component. The lifting platform is slidably connected to the frame. The driving component is connected between the frame and the lifting platform and is used to drive the lifting platform to move up and down relative to the frame. The screwing component is fixedly connected to the sleeve and slidably connected to the lifting platform. The elastic component is disposed between the screwing component and the lifting platform.

[0016] In some embodiments, the tightening unit includes a guide rod connected between the lifting platform and the frame.

[0017] In some embodiments, the electromagnet push rod mounting and adjusting device includes a second clamping unit located between the first clamping unit and the sleeve, the second clamping unit being used to clamp the push rod.

[0018] In some embodiments, the electromagnet push rod mounting and adjusting device includes a fiber optic switch, which is connected to the second clamping unit and is used to detect the push rod and control the second clamping unit to clamp the push rod.

[0019] In some embodiments, the measuring unit includes an indenter and a displacement measuring probe, the indenter being used to contact the electromagnet, and the displacement measuring probe being used to contact the push rod and measure the displacement of the push rod relative to the electromagnet.

[0020] In some embodiments, the electromagnet top rod mounting and adjusting device includes a transport unit, which includes a slide rail, a slide table, and a fixing component. The fixing component is disposed on the slide table and used to fix the electromagnet. The slide table is movable along the slide rail to transport the electromagnet to the first clamping unit.

[0021] The electromagnet push rod installation and adjustment method of this invention is based on the electromagnet push rod installation and adjustment device in the above embodiments, and includes the following steps:

[0022] S1: Place the push rod in the first position of the sleeve to position the push rod axially, and then fix the push rod;

[0023] S2: Position the electromagnet housing using the first clamping unit;

[0024] S3: Release the fixing of the push rod, and measure the displacement of the push rod relative to the electromagnet using the measuring unit;

[0025] S4: Drive the sleeve to rotate by tightening unit, so that the push rod moves from the first position to the second position;

[0026] S5: Drive the sleeve to rotate and move along the axial direction of the push rod by the tightening unit to screw the push rod into the electromagnet.

[0027] In some embodiments, in step S4, the tightening unit drives the sleeve to rotate in the opposite direction so that the push rod moves from the first position to the second position; step S5 includes the following steps:

[0028] S51: Drive the sleeve to rotate in the forward direction through the tightening unit and detect the torque. When the torque reaches the set value, stop driving the sleeve to rotate in the forward direction.

[0029] S52: The sleeve is driven to rotate in the reverse direction by the tightening unit. When the displacement measured by the measuring unit reaches the set range, the reverse rotation of the sleeve is stopped, and the push rod and the electromagnet are assembled.

[0030] In some embodiments, in step S4, the lifting platform is driven to move a set distance along the axial direction of the top rod by the driving member, and during the movement of the lifting platform, the screwing member drives the sleeve to rotate in the opposite direction. After the threaded section of the top rod contacts the threaded hole section of the electromagnet, it reacts to the screwing member, so that the screwing member moves relative to the lifting platform and causes the elastic member to deform.

[0031] In step S5, the deformation of the elastic element is restored and drives the screwing component to move. At the same time, the screwing component drives the sleeve to rotate in the forward direction so that the threaded section of the push rod engages with the threaded hole section of the electromagnet.

Detailed Implementation

[0046] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0047] like Figures 1-12 As shown, the electromagnet top rod installation and adjustment device of this embodiment includes a frame 1, a first clamping unit 2, a measuring unit 3, a sleeve 4, and a tightening unit 5.

[0048] like Figures 1-5 As shown, the first clamping unit 2 is disposed on the frame 1, and the first clamping unit 2 is used to clamp the electromagnet 9 to position the electromagnet 9. Specifically, the first clamping unit 2 includes a fixed block 21 and a movable block 22. The electromagnet 9 is placed between the fixed block 21 and the movable block 22, and the movable block 22 can move toward the fixed block 21 to clamp and position the electromagnet 9.

[0049] like Figures 1-5 As shown, the measuring unit 3 is used to detect the displacement of the push rod 91 relative to the electromagnet 9, and emits a displacement signal when the displacement reaches a set range. The measuring unit 3 is configured to detect the displacement of the push rod 91 relative to the electromagnet 9, ensuring that the extension length of the push rod 91 is within a set range after assembly.

[0050] like Figures 10-12 As shown, the sleeve 4 is provided with a positioning groove 41, and a positioning surface 42 and an anti-rotation surface 43 are provided in the positioning groove 41. The positioning surface 42 is used to position the push rod 91 axially, and the anti-rotation surface 43 is used to prevent the push rod 91 from rotating. The push rod 91 has a first position and a second position in the positioning groove 41. In the first position, the lower end face of the push rod 91 is in contact with the positioning surface 42 and the push rod 91 can rotate relative to the sleeve 4. In the second position, the outer periphery of the push rod 91 is anti-rotated in conjunction with the anti-rotation surface 43.

[0051] Specifically, the sleeve 4 is arranged vertically, and the positioning groove 41 is located at the end of the sleeve 4. Two positioning surfaces 42 are provided within the positioning groove 41, and these surfaces are arranged horizontally. When the push rod 91 is placed in the positioning groove 41, the lower end face of the push rod 91 can contact and stop with the positioning surface 42. Rotating the sleeve 4 can adjust the angle between the push rod 91 and the sleeve 4, thereby allowing the push rod 91 to move from a first position to a second position. Two anti-rotation surfaces 43 are provided. The outer periphery of the push rod 91 is machined with a flat surface 911. When the push rod 91 is in the second position, its outer surface 911 engages with the anti-rotation surface 43 of the sleeve 4 to prevent rotation. The tightening unit 5 can drive the push rod 91 to rotate via the sleeve 4 to screw it into the electromagnet 9. Furthermore, the anti-rotation surface 43 in the positioning groove 41 also serves to position the push rod 91, ensuring good coaxiality between the push rod 91 and the armature 92 inside the electromagnet 9 after assembly.

[0052] like Figures 1-5 As shown, the tightening unit 5 is located at the lower part of the sleeve 4 and connected to the sleeve 4. The tightening unit 5 is used to drive the sleeve 4 to rotate and move along the axial direction of the push rod 91. During the rotation of the sleeve 4, the push rod 91 can move from the first position to the second position. When the push rod 91 is in the second position, it is driven to rotate by the tightening unit 5 to screw into the electromagnet 9. The tightening unit 5 can receive the displacement signal of the measuring unit 3 and stop driving the sleeve 4 to rotate after receiving the displacement signal.

[0053] In the electromagnet push rod installation and adjustment device of this invention, the sleeve is provided with a positioning groove, and the push rod has a first position and a second position within the positioning groove. In the first position, the lower end face of the push rod contacts the positioning surface, facilitating the initial mounting of the electromagnet onto the outer circumference of the push rod. In the first position, the push rod can rotate relative to the sleeve. During the rotation of the sleeve driven by the tightening unit, the push rod can move from the first position to the second position, achieving the engagement between the push rod and the sleeve. Due to this engagement process, there is no need to manually control the placement angle of the push rod when placing it in the positioning groove. In the second position, the outer circumference of the push rod engages with the anti-rotation surface, allowing the tightening unit to drive the push rod to rotate via the sleeve, completing the engagement between the threaded section of the push rod and the armature inside the electromagnet.

[0054] During the screwing of the push rod into the electromagnet, the measuring unit detects the displacement of the push rod relative to the electromagnet and sends the displacement signal to the tightening unit. Once the tightening unit receives the displacement signal, it stops driving the sleeve to rotate. The assembly precision between the push rod and the electromagnet is high, and the entire installation and adjustment process of the push rod can be completed automatically, saving manpower and improving production efficiency.

[0055] In some embodiments, such as Figure 1 , 2As shown in Figures 4 and 6, the tightening unit 5 includes a lifting platform 51, a driving component 52, a screwing component 53, and an elastic component 54. The lifting platform 51 is slidably connected to the frame 1. The driving component 52 is connected between the frame 1 and the lifting platform 51, and is used to drive the lifting platform 51 to move up and down relative to the frame 1. The screwing component 53 is fixedly connected to the sleeve 4 and slidably connected to the lifting platform 51. The elastic component 54 is disposed between the screwing component 53 and the lifting platform 51. The tightening unit 5 also includes a guide rod 55, which is connected between the lifting platform 51 and the frame 1.

[0056] Specifically, the screwing component 53 can be a tightening gun. The upper part of the lifting platform 51 is slidably assembled with the frame 1 via two guide rods 55, and the lower part of the lifting platform 51 is slidably engaged with the screwing component 53. The driving component 52 can be a cylinder, the telescopic end of which is connected to the lifting platform 51 and can drive the lifting platform 51 to rise and fall. The elastic component 54 is disposed between the screwing component 53 and the lifting platform 51. When the screwing component 53 slides relative to the lifting platform 51, the elastic component 54 can generate elastic deformation. The upper part of the screwing component 53 is fixedly connected to the lower part of the sleeve 4 and is used to drive the sleeve 4 to rotate.

[0057] During the installation of the push rod, the tightening unit 5 operates as follows: the drive component 52 moves the lifting platform 51 and the screwing component 53 upwards together, while the screwing component 53 drives the sleeve 4 to rotate in the opposite direction. During the rotation of the sleeve 4, the push rod 91 moves to the second position in the positioning groove 41 and rotates together with the sleeve 4. Because the sleeve 4 drives the push rod 91 to rotate in the opposite direction, the threaded section of the push rod 91 cannot engage with the threaded hole of the armature 92 in the electromagnet 9, and the push rod 91 stops moving upwards. The drive component 52 continues to move the lifting platform 51 upwards. Due to the stopping effect of the push rod 91, the screwing component 53 no longer moves upwards, and the elastic component 54 is compressed. After the drive component 52 stops driving the lifting platform 51 upwards, the elastic component 54 has a certain amount of compression. Then the screwing component 53 rotates clockwise, the elastic component 54 extends and drives the screwing component 53 to move upwards, and the threaded section of the push rod 91 begins to engage with the threaded hole of the armature 92. During the process of the threaded section of the push rod 91 engaging with the threaded hole of the armature 92, the screwing component 53 is driven upward by the elastic component 54, making it less likely for mechanical jamming to cause thread damage.

[0058] In some embodiments, such as Figure 1 , 2As shown in Figures 4 and 6, the electromagnet push rod mounting and adjusting device includes a second clamping unit 6, which is located between the first clamping unit 2 and the sleeve 4. The second clamping unit 6 is used to clamp the push rod 91. Specifically, the second clamping unit 6 can be a gripper. After the push rod 91 is placed in the positioning groove 41 of the sleeve 4, the lower end face of the push rod 91 contacts the positioning surface 42. At this time, the axial positioning of the push rod 91 is completed, but the push rod 91 can still move in the circumferential direction. By clamping and fixing the outer periphery of the push rod 91 through the second clamping unit 6, the movement of the push rod 91 in the circumferential direction is restricted, making it easier to fit the electromagnet 9 onto the outer periphery of the push rod 91. Before the tightening unit 5 is activated, the second clamping unit 6 can release the push rod 91.

[0059] In some embodiments, such as Figure 1 , 2 As shown in Figures 4 and 6, the electromagnet push rod installation and adjustment device includes a fiber optic switch 7. The fiber optic switch 7 is connected to the second clamping unit 6, and the fiber optic switch 7 is used to detect the push rod 91 and control the second clamping unit 6 to clamp the push rod 91. Specifically, the fiber optic switch 7 is located on one side of the sleeve 4. The fiber optic switch 7 is used to detect whether the push rod 91 is inserted into the positioning groove 41 of the sleeve 4. When the push rod 91 is detected to be in the positioning groove 41, the second clamping unit 6 is controlled to clamp the push rod 91 to facilitate the installation of the electromagnet 9.

[0060] In some embodiments, such as Figure 1 , 4 As shown in Figure 7, the measuring unit 3 includes a pressure head 31 and a displacement measuring probe 32. The pressure head 31 is used to contact the electromagnet 9, and the displacement measuring probe 32 is used to contact the push rod 91 and measure the displacement of the push rod 91 relative to the electromagnet 9. Specifically, the displacement measuring probe 32 is slidably fitted inside the pressure head 31, and the pressure head 31 contacts the upper end face of the armature 92 inside the electromagnet 9. The push rod 91 passes through the armature 92 and extends into the interior of the pressure head 31, with the upper end face of the push rod 91 contacting the displacement measuring probe 32. The measuring unit 3 detects the displacement of the push rod 91 relative to the armature 92 through the above configuration, thereby determining the extension length of the push rod 91.

[0061] In some embodiments, such as Figures 1-5As shown, the electromagnet push rod mounting and adjusting device includes a transport unit 8, which includes a slide rail 81, a slide table 82, and a fixing component 83. The fixing component 83 is disposed on the slide table 82 and used to fix the electromagnet 9. The slide table 82 can move along the slide rail 81 to transport the electromagnet 9 to the first clamping unit 2. Specifically, the transport unit 8 is located above the first clamping unit 2. The slide rail 81 is fixedly connected to the frame 1. The slide table 82 slides and fits on the slide rail 81. The fixing component 83 is used to fix the slide table 82. The measuring unit 3 is disposed on the fixing component 83. The transport unit 8 first moves the electromagnet 9 horizontally from its original position to above the table, then lowers it and places the electromagnet 9 on the table. The distance of descent is limited by the limiting device 84. After the push rod 91 and the electromagnet 9 are assembled, the transport unit 8 then transports the electromagnet 9 back to its original position.

[0062] The working process of the electromagnet push rod installation and adjustment device according to an embodiment of the present invention is described below:

[0063] like Figures 1-5 As shown, the push rod 91 is placed in the sleeve 4. After the fiber optic switch 7 detects the push rod 91, it controls the second clamping unit 6 to clamp the push rod 91. The transport unit 8 transports the electromagnet 9 to the table. At this time, the upper part of the push rod 91 passes through the electromagnet 9, and the first clamping unit 2 clamps and positions the electromagnet 9. After the electromagnet 9 is clamped and positioned, the second clamping unit 6 releases the push rod 91.

[0064] The driving component 52 drives the lifting platform 51 and the screwing component 53 to move upward together. At the same time, the screwing component 53 drives the sleeve 4 to rotate in the opposite direction. During the rotation of the sleeve 4, the push rod 91 moves to the second position in the positioning groove 41 and rotates together with the sleeve 4.

[0065] As the sleeve 4 drives the push rod 91 to rotate in the opposite direction, the threaded section of the push rod 91 cannot engage with the threaded hole of the armature 92 inside the electromagnet 9. The push rod 91 moves upward until the threaded section contacts the threaded hole of the armature 92 and then stops moving upward. Meanwhile, the drive component 52 continues to drive the lifting platform 51 to move upward. Due to the stopping effect of the push rod 91, the screwing component 53 no longer moves upward, and the elastic component 54 is compressed. After the drive component 52 stops driving the lifting platform 51 to move upward, the elastic component 54 has a certain amount of compression.

[0066] The screwing component 53 drives the push rod 91 to rotate in the forward direction. The elastic element 54 extends and drives the screwing component 53 to move upward. The threaded section of the push rod 91 begins to engage with the threaded hole of the armature 92. After the screwing component 53 reaches the set torque, it stops driving the push rod 91 to rotate. At this time, the push rod 91 is in an over-tightened state. This step can be used to check whether the threaded hole is qualified.

[0067] The screwing component 53 drives the push rod 91 to rotate in the opposite direction, and the push rod 91 begins to move downward. When the measuring unit 3 detects that the displacement of the push rod 91 has reached the set range, the screwing component 53 stops rotating in the opposite direction, and the push rod 91 and the electromagnet 9 are assembled. The driving component 52 drives the lifting platform 51, the screwing component 53 and the sleeve 4 to move downward and reset. The transport unit 8 transports the assembled electromagnet 9 back to its original position, and then the installation of the next set of electromagnet 9 push rods 91 can begin.

[0068] The following describes the installation and adjustment method of the electromagnet push rod according to an embodiment of the present invention.

[0069] The electromagnet push rod installation and adjustment method of this invention is based on the electromagnet push rod installation and adjustment device in the above embodiments, and includes the following steps:

[0070] S1: Position the push rod 91 in the first position of the sleeve 4 to position the push rod 91 axially, and then fix the push rod 91. After fixing the push rod 91, it is easy to install the electromagnet 9 on it.

[0071] S2: The electromagnet 9 housing is positioned by the first clamping unit 2. Clamping and positioning the electromagnet ensures that the position of the electromagnet 9 is fixed when the top rod 91 is installed, resulting in good installation accuracy.

[0072] S3: Release the fixing of the push rod 91, and measure the displacement of the push rod 91 relative to the electromagnet 9 through the measuring unit 3.

[0073] S4: The tightening unit 5 drives the sleeve 4 to rotate, causing the push rod 91 to move from the first position to the second position. The movement of the push rod 91 from the first position to the second position is a positioning process, at which the push rod 91 and the sleeve 4 stop rotating. This process eliminates the need to adjust the angle of the push rod 91 when placing it on the sleeve 4, simplifying the assembly process and improving assembly efficiency.

[0074] S5: Drive the sleeve 4 to rotate and move along the axial direction of the push rod 91 by tightening unit 5 to screw the push rod 91 into the electromagnet 9.

[0075] In some embodiments, in step S4, the tightening unit 5 drives the sleeve 4 to rotate in the opposite direction so that the push rod 91 moves from the first position to the second position; step S5 includes the following steps:

[0076] S51: The sleeve 4 is driven to rotate forward by the tightening unit 5 and the torque is detected. When the torque reaches the set value, the forward rotation of the sleeve 4 is stopped.

[0077] S52: The sleeve 4 is driven to rotate in the reverse direction by the tightening unit 5. When the displacement measured by the measuring unit 3 reaches the set range, the reverse rotation of the sleeve 4 is stopped, and the push rod 91 and the electromagnet 9 are assembled.

[0078] First, the push rod 91 is screwed into the armature 92 of the electromagnet 9 by setting the torque. During this process, the thread quality of the push rod 91 and the armature 92 can be determined based on the torque value and the displacement data detected by the measuring unit 3. Then, the extension height of the push rod 91 is adjusted to the set range by reverse screwing.

[0079] In some embodiments, in step S4, the lifting platform 51 is driven to move a set distance along the axial direction of the top rod 91 by the driving member 52, and during the movement of the lifting platform 51, the screwing member 53 drives the sleeve 4 to rotate in the opposite direction. After the threaded section of the top rod 91 contacts the threaded hole section of the electromagnet 9, it reacts to the screwing member 53, so that the screwing member 53 moves relative to the lifting platform 51 and causes the elastic member 54 to deform.

[0080] In step S5, the elastic element 54 recovers its deformation and drives the screwing element 53 to move. At the same time, the screwing element 53 drives the sleeve 4 to rotate in the forward direction so that the threaded section of the push rod 91 engages with the threaded hole section of the electromagnet 9.

[0081] During the process of the threaded section of the push rod 91 engaging with the threaded hole of the armature 92, the screwing component 53 is driven to move by the elastic component 54, making it less likely for the push rod 91 and the armature 92 inside the electromagnet 9 to experience mechanical jamming that could damage the threads.

[0082] In the description of this invention, it should be understood that the terms "center," "longitudinal," "lateral," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," "outer," "clockwise," "counterclockwise," "axial," "radial," and "circumferential" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.
