Description

Technical Field

[0001] This utility model relates to the field of fan main shaft production technology, and in particular to a bonding and fixing device for an air-suspended fan main shaft. Background Technology

[0002] In the manufacturing process of the main shaft of an air-suspended blower, the main shaft, as the core power component, must possess extremely high magnetic properties to achieve efficient energy conversion. Its operating speed often exceeds 40,000 rpm, and it is precisely connected to high-speed rotating components such as the impeller and cooling fan. Because the main shaft has frictional contact with the bearings during start-up and shutdown, and is subjected to complex alternating loads over long periods, it places almost stringent requirements on its material strength, wear resistance, and dynamic balance performance. The manufacturing quality of the main shaft directly affects the blower's operational stability, energy efficiency, and lifespan.

[0003] Traditional bonding and fixing devices typically place the spindle horizontally in a fixing fixture. This method reveals significant defects in the process: in the horizontally fixed state, the highly fluid adhesive tends to accumulate on the lower side of the spindle under the influence of gravity, resulting in an excessively thin adhesive layer on the upper side or even localized lack of adhesive, while the adhesive layer on the lower side is too thick and accumulates, causing radial eccentricity after curing. Utility Model Content

[0004] Purpose of the invention: The purpose of this utility model is to provide a bonding and fixing device for the main shaft of an air suspension fan. Through a control mechanism driven by a servo motor, the base can automatically tilt during the main shaft placement stage, so that the installation space of the upper module is tilted upward, which facilitates the quick alignment of the main shaft and improves the installation efficiency of the workers. After the upper and lower modules are closed, the base automatically returns to the vertical state, ensuring that the main shaft is in the optimal gravity distribution position during the curing process, eliminating problems such as adhesive layer deviation or air bubble residue, and increasing the bonding qualification rate to over 97%.

[0005] Technical solution:

[0006] A bonding and fixing device for the main shaft of an air-suspended fan includes a lower module, one end of which is fixedly mounted with a baffle, and the other end of which is provided with a pressing mechanism. An upper module is detachably mounted on the upper end of the lower module. The lower module, the upper module, the baffle, and the pressing mechanism form a fixing space for the main shaft. The lower module, the baffle, and the pressing mechanism are all fixedly mounted on a base. The base is connected to a control mechanism that controls the rotation of the main shaft, thereby driving the main shaft to rotate in the plane containing its axial and height directions.

[0007] Furthermore, the pressing mechanism includes a push rod and a control component, and a pressing head is provided at one end of the push rod near the fixed space.

[0008] Furthermore, the control component is a cylinder.

[0009] Furthermore, the control mechanism includes a base, on which a servo motor is mounted, and the servo motor is connected to a rotating shaft, which is fixedly connected to the base.

[0010] Furthermore, the end of the baffle near the lower module is provided with a positioning groove adapted to one end of the spindle.

[0011] Furthermore, the lower module has a threaded groove on its side end, and the upper module has a mounting groove corresponding to the threaded groove. The screw passes through the mounting groove and is threaded into the threaded groove.

[0012] Furthermore, the lower module has a positioning shaft on its side, and the upper module has a corresponding positioning hole on its side.

[0013] Furthermore, the control mechanism controls the base to rotate at an angle greater than or equal to 60°, and one extreme position of the rotation is the position where the main axis is vertical.

[0014] Beneficial effects:

[0015] 1. Through the control mechanism driven by the servo motor, the base can automatically tilt during the spindle placement stage, so that the installation space of the upper module is tilted upward, which facilitates the quick alignment of the spindle and improves the installation efficiency of the workers. After the upper and lower modules are closed, the base automatically returns to the vertical state, ensuring that the spindle is in the optimal gravity distribution position during the curing process, eliminating problems such as glue layer deviation or bubble residue, and increasing the bonding qualification rate to over 97%.

[0020] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1-4As shown, a bonding and fixing device for the main shaft of an air-suspended fan includes a lower module 1. A baffle 2 is fixedly installed at one end of the lower module 1, and a pressing mechanism 3 is provided at the other end of the lower module 1. An upper module 4 is detachably installed at the upper end of the lower module 1. The lower module 1, upper module 4, baffle 2, and pressing mechanism 3 form a fixing space for the main shaft 5. The lower module 1, baffle 2, and pressing mechanism 3 are all fixedly installed on a base 6. The base 6 is connected to a control mechanism 7 that controls its rotation, thereby driving the main shaft 5 to rotate in the plane containing its axial and height directions. The closure of the lower module 1 and upper module 4 forms an annular fixing space. With the limiting effect of the baffle 2 and the pressing effect of the pressing mechanism 3, the circumferential constraint of the main shaft 5 is achieved. The control mechanism 7 drives the base 6 to rotate, causing the main shaft 5 to tilt or be vertically positioned in the axial-height plane.

[0023] In this embodiment, the pressing mechanism 3 includes a push rod 31 and a control component 32. A pressing head 33 is provided at one end of the push rod 31 near the fixed space. The control component 32 (such as a cylinder) drives the push rod 31 to move axially, thereby causing the pressing head 33 to apply radial clamping force to the spindle 5. The contact surface between the pressing head 33 and the spindle is covered with a flexible material (such as polyurethane), which ensures uniform distribution of clamping force and prevents damage to the spindle surface, making it particularly suitable for protecting the brittle coating of magnetic rotors.

[0024] In this embodiment, the control component 32 is a cylinder.

[0025] In this embodiment, the control mechanism 7 includes a base 71, on which a servo motor 72 is mounted. The servo motor is connected to a rotating shaft 73, which is fixedly connected to the base 6. After receiving an angle command, the servo motor 72 drives the rotating shaft 73 to rotate, thereby causing the base 6 and the module assembly fixed thereon to rotate as a whole. The servo motor controls the angle with an accuracy of ±0.1°, ensuring that the spindle tilt angle can accurately match the glue flow characteristics.

[0026] In this embodiment, the end of the baffle 2 near the lower module 1 is provided with a positioning groove 21 that is adapted to one end of the main shaft.

[0027] In this embodiment, the lower module 1 has a threaded groove 11 on its side, and the upper module 4 has a mounting groove 41 corresponding to the threaded groove. The screw 8 passes through the mounting groove and is threaded into the threaded groove. After the screw 8 is screwed into the threaded groove 11, the upper module 4 is pressed onto the lower module 1 by the thread preload.

[0028] In this embodiment, a positioning shaft 12 is provided on the side end of the lower module 1, and a positioning hole 42 is correspondingly provided on the side end of the upper module 4. When the upper module 4 is closed, the positioning shaft 12 is inserted into the positioning hole 42 to achieve radial alignment of the upper and lower modules.

[0029] In this embodiment, the control mechanism 7 controls the base 6 to rotate at an angle greater than or equal to 60°, and one extreme position of the rotation is the vertical position of the main axis. In the vertical position, the adhesive flows evenly and horizontally along the circumference of the main axis under the action of gravity, and air bubbles rise to the non-stressed area and are discharged.

[0030] Working principle: such as Figure 1 As shown, the control mechanism 7 drives the base 6 to rotate to an inclined angle, creating an inclined fixed space formed by the lower module 1 and the baffle 2. At this time, the operator slides the main shaft 5 into the inclined direction from the high-end opening side. Under the action of gravity, the main shaft 5 naturally falls into the positioning groove 21 of the baffle 2, achieving rapid axial positioning. The positioning hole 42 of the upper module 4 is inserted into the positioning shaft 12 of the lower module 1 to eliminate radial misalignment. The screw 8 is screwed in to rigidly connect the upper and lower modules, forming a closed annular fixed space. The pressing mechanism 3 is activated: the cylinder 32 drives the push rod 31 and the pressing head 33 to apply radial pressing force to the main shaft 5. After the main shaft 5 is loaded, the upper module 4 is closed.

[0031] like Figure 2 As shown, after the upper and lower modules and the pressing mechanism 3 fix the main shaft, the servo motor 72 of the control mechanism 7 drives the base 6 to rotate to a vertical position, and the axis of the main shaft 5 is parallel to the direction of gravity. In this state, the high viscosity glue flows evenly in the circumferential direction under the action of gravity.

[0032] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
