Description

Technical Field

[0001] The present invention relates to the technical field of shaft threading equipment, in particular to a shaft threading device with a guide structure. Background Art

[0002] Currently, the process of threading the shaft between two folded metal sheets on a product can usually only be completed manually, which is a bottleneck process on the production line. Manual production has disadvantages such as high labor costs and high labor intensity. Because the length of the product shaft is compatible with the spacing between the axial holes in the two metal sheets, if a clamping component such as a finger cylinder is simply used to clamp the upper end of the product shaft and insert it through the axial hole in the metal sheet, during assembly, the product shaft will inevitably not be able to be inserted into the axial hole of the metal sheet on the bottom side of the product due to the length limitation (and the upper end is partially clamped by the clamping component). Therefore, the clamping component needs to be loosened. When the clamping component is loosened, the lower end of the product shaft, because it has not yet been inserted into the axial hole of the metal sheet on the bottom side, may become skewed, which may affect the threading defect. Therefore, an external tool is required to guide the insertion to ensure that the lower end of the product shaft can be smoothly inserted into the axial hole on the bottom side of the product. This assembly process is not only difficult to operate, which affects overall efficiency, but also labor-intensive and time-consuming, which is not conducive to reducing production costs. Summary of the Invention

[0003] In view of the shortcomings of the prior art, the present invention provides a shaft threading device with a guide structure, which mainly solves the technical problem that the shaft threading and assembly process of the product shaft in the two shaft holes of the product in the prior art is relatively difficult.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0005] A shaft threading device with a guiding structure includes a shaft threading mechanism and a guiding mechanism arranged relatively upper and lower, and a positioning support part arranged between the shaft threading mechanism and the guiding mechanism. The product to be threaded is positioned on the positioning support part. The shaft threading mechanism is provided with a first lifting drive component and a clamping component driven by the first lifting drive component to perform lifting movement. The shaft of the product to be assembled is clamped and positioned on the clamping component and corresponds axially to the two shaft holes of the product in the upper and lower directions. The guiding mechanism is provided with a second lifting drive component and a guiding rod driven by the second lifting drive component to perform lifting movement. The guiding rod corresponds axially to the shaft hole of the product in the upper and lower directions, and the guiding rod is configured to generate a magnetic attraction force on the product shaft, and then the lifting action of the guiding rod generates a traction and correction effect on the shaft threading process of the product shaft in the shaft hole of the product.

[0006] Furthermore, the axis threading mechanism includes an axis threading mechanism main body, an axis threading mechanism lifting part is provided on the axis threading mechanism main body, the first lifting drive component is fixed on the axis threading mechanism main body, and the axis threading mechanism lifting part is driven to move up and down relative to the axis threading mechanism main body by the first lifting drive component, and the clamping component is provided on the axis threading mechanism lifting part, the guide mechanism includes a guide mechanism main body, a guide mechanism lifting part is provided on the guide mechanism main body, the second lifting drive component is fixed on the guide mechanism main body, and the guide mechanism lifting part is driven to move up and down relative to the guide mechanism main body by the second lifting drive component, and the guide rod is provided on the guide mechanism lifting part.

[0007] Furthermore, the guide rod is a guide rod structure made of magnetic material.

[0008] Furthermore, the guide rod is a guide rod structure made of a magnetically friendly material, and a permanent magnet is connected to the guide rod structure.

[0009] Furthermore, the clamping component on the lifting part of the shaft-threading mechanism is a finger cylinder.

[0010] Furthermore, the first lifting drive component is a servo motor, which is fixedly arranged on the main body of the through-axis mechanism, and the driving end of the servo motor is mechanically connected to the lifting part of the through-axis mechanism through the cooperation of the screw rod and the nut sleeve, and then the lifting part of the through-axis mechanism is driven by the servo motor to lift up and down relative to the main body of the through-axis mechanism.

[0011] Furthermore, a plurality of positioning holes are provided on the positioning support portion, and the shaft-penetrating mechanism and / or the guiding mechanism are provided with positioning pins for positioning and cooperating with the positioning holes.

[0012] Furthermore, a lower pressure block is provided on the lifting part of the through-axis mechanism, which is lifted and lowered synchronously with the clamping part, and a pressed block is provided on the lifting part of the guide mechanism. The lower pressure block and the pressed block are arranged correspondingly up and down. The second lifting drive component is a cylinder, and when the solenoid valve of the second lifting drive component is switched to the middle deflation state to release the thrust of the cylinder, the lifting part of the guide mechanism is configured to be able to descend synchronously with the first lifting drive component by the mutual cooperation of the descending lower pressure block and the pressed block.

[0013] Furthermore, when the lower pressing block descends and presses on the pressed block, the opposite ends of the product shaft and the guide rod approach or abut against each other.

[0014] The above technical solution has the following advantages or beneficial effects:

[0015] In the shaft threading device with a guide structure described in the present invention, the product to be assembled is positioned on a positioning support, the upper end of the product shaft is partially clamped and fixed on the clamping component, and the guide mechanism is located below the shaft threading mechanism. During operation, a second lifting drive component on the guide mechanism drives the guide rod to rise and then insert it into the shaft hole on the bottom side of the product. The product shaft is then inserted into the shaft hole on the top side of the product through the shaft threading mechanism. By controlling the insertion stroke of the two, the product shaft and the guide rod are brought closer to each other. The guide rod and the product shaft then descend synchronously. The magnetic attraction force of the guide rod on the product shaft guides the shaft threading process until the guide rod exits the shaft hole on the bottom side of the product. The guide rod then guides the lower end of the product shaft to pass through the corresponding shaft hole on the bottom side of the product, thereby completing the shaft threading assembly process of the product shaft between the two shaft holes of the product. The shaft threading device with a guide structure has a relatively simple overall structure, is quick, convenient, and efficient to operate, and facilitates the magnetic attraction to guide the shaft threading operation, thereby reducing the alignment accuracy requirements between the guide rod and the product shaft and facilitating guidance.

[0023] Please refer to the attached Figure 1 To the attached Figure 3 An embodiment of the present invention provides an axis threading device with a guiding structure, including an axis threading mechanism 1 and a guiding mechanism 2 arranged opposite to each other in an upper and lower direction, and a positioning support part 3 arranged between the axis threading mechanism 1 and the guiding mechanism 2. The product 4 to be threaded is positioned on the positioning support part 3. The axis threading mechanism 1 is provided with a first lifting drive component 11 and a clamping component 12 driven by the first lifting drive component 11 to perform lifting movement.

The guiding rod 22 corresponds axially to the axis hole 41 of the product 4 in the upper and lower directions, and the guiding rod 22 is configured to generate a magnetic attraction force on the product shaft 5, and then the lifting action of the guiding rod 22 generates a traction and correction effect on the axis threading process of the product shaft 5 in the axis hole 41 of the product 4. It can be understood that in one of the preferred application scenarios of this embodiment, the product 4 to be assembled is positioned on the positioning support part 3, the upper end of the product shaft 5 is partially clamped and fixed on the clamping part 12, and the guiding mechanism 2 is located below the axis penetration mechanism 1. During operation, the second lifting drive part 21 on the guiding mechanism 2 drives the guiding rod 22 to rise and then insert it from the axis hole 41 on the bottom side of the product 4, and then the product shaft 5 is inserted from the axis hole 41 on the top side of the product 4 through the axis penetration mechanism 1. By controlling the insertion stroke of the two, the product shaft 5 and the guiding rod 22 are close to each other, and then the guiding rod 22 and the product shaft 5 are synchronously lowered, and the magnetic attraction force of the guiding rod 22 on the product shaft 5 is used to guide the axis penetration process of the product shaft 5, until the guiding rod 22 exits the axis hole 41 on the bottom side of the product 4 downward, the guiding rod 22 can guide the lower end of the product shaft 5 to pass through the axis hole 41 on the bottom side of the product 4 accordingly, thereby completing the axis penetration assembly process of the product shaft 5 between the two axis holes 41 of the product 4. The overall structure of the shaft threading device with a guiding structure is relatively simple, the operation is quick, convenient and efficient, and it is beneficial to guide the shaft threading operation of the product shaft 5 by magnetic attraction, which is beneficial to reducing the alignment accuracy requirements between the rod 22 and the product shaft 5 and facilitating guidance.

[0024] Please refer to the attached Figure 1 To the attached Figure 3In one preferred embodiment, the axis threading mechanism 1 includes an axis threading mechanism main body 13, and an axis threading mechanism lifting part 14 is provided on the axis threading mechanism main body 13. The first lifting driving component 11 is fixed on the axis threading mechanism main body 13, and the axis threading mechanism lifting part 14 is driven to move up and down relative to the axis threading mechanism main body 13 by the first lifting driving component 11, and the clamping component 12 is provided on the axis threading mechanism lifting part 14. The guiding mechanism 2 includes a guiding mechanism main body 23, and a guiding mechanism lifting part 22 is provided on the guiding mechanism main body 23. The second lifting driving component 21 is fixed on the guiding mechanism main body 23, and the guiding mechanism lifting part 24 is driven to move up and down relative to the guiding mechanism main body 23 by the second lifting driving component 21, and the guiding rod 22 is provided on the guiding mechanism lifting part 24.

[0025] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the guide rod 22 is a guide rod structure made of a magnetic material, and a permanent magnet 25 (such as a neodymium iron boron permanent magnet) is connected to the guide rod structure. However, those skilled in the art will appreciate that in other embodiments, the guide rod 22 can also be a guide rod structure made of a magnetic material, so that the guide rod 22 itself can generate a magnetic attraction force on the product shaft 5 (a product shaft made of a magnetic metal such as iron).

[0026] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the clamping member 12 on the lifting portion 14 of the threading mechanism is a finger cylinder. However, those skilled in the art will appreciate that in other embodiments, the clamping member 12 may also be other conventional clamping and fixing structures in the prior art, and is not limited to the specific implementation disclosed in this embodiment.

[0027] Please refer to the attached Figure 1 To the attached Figure 3 In one preferred embodiment, the first lifting drive component 11 is a servo motor, which is fixedly mounted on the shaft-threading mechanism body 13, and the driving end of the servo motor is mechanically connected to the shaft-threading mechanism lifting part 14 through the cooperation of the screw rod and the nut sleeve, and then the shaft-threading mechanism lifting part 14 is driven by the servo motor to lift up and down relative to the shaft-threading mechanism body 13.

[0028] Please refer to the attached Figure 1 In one preferred embodiment, the positioning support portion 3 is provided with a plurality of positioning holes 31, and the shaft threading mechanism 1 and / or the guide mechanism 2 are provided with positioning pins 6 for cooperating with the positioning holes 31. The cooperating positioning of the positioning pins 6 on the shaft threading mechanism 1 and / or the guide mechanism 2 with the positioning holes 31 on the positioning support portion 3 can improve the positioning accuracy of the product 4 to be threaded.

[0029] Please refer to the attached Figure 1 To the attached Figure 3 In one of the preferred embodiments, a lower pressure block 15 is provided on the shaft-threading mechanism lifting part 14, which is synchronously lifted and lowered with the clamping part 12, and a pressed block 26 is provided on the guiding mechanism lifting part 24. The lower pressure block 15 and the pressed block 26 are arranged correspondingly up and down. The second lifting drive component 21 is a cylinder, and the cylinder origin is at a low position. When the cylinder is inhaled, the guiding mechanism lifting part 22 is lifted to a high position. When the solenoid valve of the cylinder is switched to the middle deflation state, both ends of the cylinder body are connected to the atmosphere, the cylinder thrust is released, and the guiding mechanism lifting part 22 is maintained at its original high position, and can be moderately pressed down and lowered under the downward pressure of the lower pressure block 15. In this way, the guiding mechanism lifting part 24 is configured to be able to fall synchronously with the first lifting drive component 11 by the mutual cooperation of the descending lower pressure block 15 and the pressed block 26. In one preferred embodiment, when the lower pressing block 15 descends and presses on the pressed block 26, the opposite ends of the product shaft 5 and the guide rod 22 are close to or abut against each other. During operation, the second lifting drive component 21 first controls the guide rod 22 to rise so that the guide rod 22 is correspondingly inserted into the shaft hole 41 on the bottom side of the product 4, and then, the axis-threading mechanism 1 controls the product shaft 5 to be inserted into the shaft hole 41 on the top side of the product 4, until the lower pressure block 15 descends and presses on the pressed block 26. At this time, the opposite ends of the product shaft 5 and the guide rod 22 are close to or against each other, and then, the clamping component 12 is released to release the clamping fixation on the upper end of the product shaft 5, and the axis-threading mechanism 1 controls the lower pressure block 15 to continue to descend, and the lower pressure block 15 presses the pressed block 26 to descend synchronously. In this way, the descending guide rod 22 guides the product shaft 5 to descend synchronously through the magnetic force until the lower end of the product shaft 5 is correspondingly inserted into the shaft hole 41 on the top side of the product 4, thereby completing the assembly of the product shaft 5 between the two shaft holes 41 of the product 4. In this embodiment, preferably, the positioning support portion 3 can be fixed on a circularly rotating turntable, and a plurality of positioning support portions 3 can be arranged in a ring shape during assembly, so that continuous through-shaft assembly of the product can be achieved.
