DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present disclosure.

[0028] In common coating equipment, since the cavity sizes of different coating equipment are different, it is necessary to select magnetic fluids of different specifications according to the cavity size, which leads to many problems such as poor versatility, high production cost, and difficult installation.

[0029] In response to the above problems, the present embodiment provides a magnetic fluid component, in which the magnetic fluid body is connected to the rear support component through an extension shaft and locked by a locking component. When the cavity size changes, the extension shaft is removed and replaced to adapt to the change in cavity size without replacing the magnetic fluid body. This effectively improves versatility and helps reduce production and use costs and installation difficulty.

[0030] The following will be combined Figures 1 to 9 The magnetic fluid component of this embodiment is described. The magnetic fluid component of this embodiment is applied to a coating device, which includes a cavity and a carrier plate 700 located in the cavity. The magnetic fluid component is installed in the cavity to realize power transmission, drive the carrier plate 700 to move, and realize rotation sealing at the connection position with the cavity.

[0031] like Figures 1 to 3As shown, the magnetic fluid assembly of the embodiment of the present disclosure includes a magnetic fluid body 100, an extension shaft 200, a locking assembly 300 and a rear section support assembly 400. Among them, the magnetic fluid body 100 has an input end 110 and an output end 120, and the input end 110 is used to connect the driving source. When the driving source is powered by the input end 110, the output end 120 of the magnetic fluid body 100 can output power, and the magnetic fluid body 100 can be installed on the cavity to achieve power transmission and transfer sealing. Since the main improvement content of this embodiment does not lie in the structure of the magnetic fluid body 100, the structure of the magnetic fluid body 100 is not repeated. The extension shaft 200 is coaxially arranged with the magnetic fluid body 100, and the first end of the extension shaft 200 is detachably connected to the output end 120. The locking assembly 300 is connected to the output end 120 and the first end of the extension shaft 200 respectively, and is configured to lock the relative position between the output end 120 and the first end of the extension shaft 200. The rear support assembly 400 is detachably connected to the second end of the extension shaft 200 .

[0032] In this embodiment, the first end of the extension shaft 200 and the output end 120 and the second end of the extension shaft 200 and the rear support assembly 400 are all detachably connected, so the extension shaft 200 can be disassembled and replaced, and the appropriate extension shaft 200 size can be selected according to the cavity structure of different sizes of the coating equipment, which has good versatility and does not need to design the magnetic fluid assembly separately according to the cavity size, effectively reducing the production and use costs and installation difficulty. The locking assembly 300 can realize the position locking between the output end 120 and the extension shaft 200 to ensure the stability of power transmission. When the extension shaft 200 needs to be replaced, the locking assembly 300 can be unlocked for easy operation.

[0033] Combination Figure 1 , Figure 4 and Figure 5 In some embodiments of the present disclosure, the locking assembly 300 includes a first locking member 310 and a second locking member 320. The first locking member 310 is located on one side of the position where the output end 120 and the extension shaft 200 meet, and the second locking member 320 is located on the other side of the position where the output end 120 and the extension shaft 200 meet, and the second locking member 320 is detachably connected to the first locking member 310.

[0034] In this embodiment, when the first locking member 310 and the second locking member 320 are connected, the output end 120 and the extension shaft 200 can be limited and clamped on both sides of the connection position between the output end 120 and the extension shaft 200 to ensure that the relative position of the output end 120 and the extension shaft 200 is fixed. When the extension shaft 200 needs to be disassembled or replaced, the first locking member 310 and the second locking member 320 can be removed so that the extension shaft 200 can be detached from the output end 120.

[0035] In some embodiments of the present disclosure, the first locking member 310 includes a first arc-shaped portion and first ears disposed at both ends of the first arc-shaped portion, and the inner side of the first arc-shaped portion is in contact with the output end 120 and the first end of the extension shaft 200. The second locking member 320 includes a second arc-shaped portion and second ears disposed at both ends of the second arc-shaped portion, and the inner side of the second arc-shaped portion is in contact with the output end 120 and the first end of the extension shaft 200. The two first ears correspond to the two second ears one by one, and the first ears are fixed to the corresponding second ears by bolts.

[0036] Specifically, the first arc portion, the first ear portion, the second arc portion and the second ear portion are all plate structures. The first arc portion is arranged opposite to the second arc portion, and the inner diameter of the first arc portion and the second arc portion is equal to or slightly larger than the diameter of the output end 120 and the extension shaft 200. Two first ears and two second ears are respectively provided, and the two first ears and the two second ears are connected by bolts one by one. For example, the first ear portion and the second ear portion are respectively provided with through holes, and the bolts are passed through the through holes of the first ear portion and the second ear portion and locked by nuts; or, one of the first ear portion and the second ear portion is provided with a through hole, and the other is provided with a threaded hole, and the bolts are passed through the through hole and connected to the first ear portion or the second ear portion through the threaded hole to lock the first ear portion and the second ear portion.

[0037] Optionally, the first locking member 310 and the second locking member 320 are symmetrically arranged, thereby reducing the production difficulty and the production cost.

[0038] In some embodiments of the present disclosure, the output end 120 is provided with a first positioning groove 121, and the first end of the extension shaft 200 is provided with a second positioning groove 201. The locking assembly 300 has a first limiting structure 311 and a second limiting structure 312, the first limiting structure 311 is located in the first positioning groove 121, and the second limiting structure 312 is located in the second positioning groove 201.

[0039] The first positioning groove 121 and the second positioning groove 201 are preferably annular groove structures. Accordingly, the first limiting structure 311 and the second limiting structure 312 are preferably annular protrusions, and the first limiting structure 311 and the second limiting structure 312 are arranged on the inner side of the first arc-shaped portion and / or the second arc-shaped portion. When the magnetic fluid body 100 and the extension shaft 200 are docked, the first limiting structure 311 is located in the first positioning groove 121, and the second limiting structure 312 is located in the second positioning groove 201.

[0040] Under the action of the first limiting structure 311 and the second limiting structure 312, the magnetic fluid body 100 and the extension shaft 200 can be axially limited to avoid axial relative sliding of the magnetic fluid body 100 and the extension shaft 200, thereby improving the stability of the connection between the magnetic fluid body 100 and the extension shaft 200.

[0041] In some embodiments of the present disclosure, a first inclined surface is provided on one side of the first positioning groove 121 close to the second positioning groove 201 and / or on one side of the second positioning groove 201 close to the first positioning groove 121. Preferably, a first inclined surface is provided on each side of the first positioning groove 121 and the second positioning groove 201 close to each other. The first inclined surface intersects the radial direction of the extension shaft 200 and the axial direction of the extension shaft 200, respectively, so that the first positioning groove 121 and / or the second positioning groove 201 is an expanded annular groove structure with a right-angle trapezoidal cross section. The first inclined surface contacts and cooperates with the first limiting structure 311 or the second limiting structure 312.

[0042] By setting the first inclined surface, clamping can be achieved by utilizing the pressure of the first limiting structure 311 and the second limiting structure 312. Specifically, when the first locking member 310 and the second locking member 320 are locked by bolts, the first limiting structure 311 and / or the second limiting structure 312 on the first locking member 310 and the second locking member 320 apply a force to their corresponding first inclined surfaces. This force can make the magnetic fluid body 100 and the extension shaft 200 tend to approach each other, thereby achieving clamping and ensuring that the magnetic fluid body 100 and the extension shaft 200 do not loosen during rotation.

[0043] Optionally, the first limiting structure 311 and / or the second limiting structure 312 are provided with a second inclined surface that is parallel to and in contact with the first inclined surface. Preferably, the first limiting structure 311 and the second limiting structure 312 are respectively provided with a second inclined surface that is parallel to and in contact with the corresponding first inclined surface. Providing the second inclined surface is conducive to increasing the contact area between the first limiting structure 311 or the second limiting structure 312 and the first inclined surface, preventing the first inclined surface from being damaged by extrusion deformation, and can also reduce the friction between the first limiting structure 311 or the second limiting structure 312 and the first inclined surface, so that the magnetic fluid body 100 and the extension shaft 200 are more likely to slide in a direction close to each other, achieving a better locking effect, and in addition, it can also reduce the difficulty of installation.

[0044] Combination Figure 6In some embodiments of the present disclosure, the locking assembly 300 further includes a first positioning member (not shown in the figure) and a second positioning member (not shown in the figure). The first positioning member and the second positioning member are threaded members, such as bolts or screws. The first locking member 310 and / or the second locking member 320 are provided with a first positioning hole 330 and a second positioning hole 340. The first positioning hole 330 and the second positioning hole 340 are threaded holes. The first positioning hole 330 and the second positioning hole 340 are arranged at intervals along the axial direction of the extension shaft 200. The first positioning member is connected to the first locking member 310 or the second locking member 320 through the first positioning hole 330, and abuts against the side wall of the output end 120. The second positioning member is connected to the first locking member 310 or the second locking member 320 through the second positioning hole 340, and abuts against the side wall of the extension shaft 200.

[0045] When the first positioning member and the second positioning member are in a tightened state, the first positioning member presses against the output end 120 and the second positioning member presses against the extension shaft 200, which can limit the output end 120 and the extension shaft 200 to prevent the output end 120 and the extension shaft 200 from relative movement or rotation.

[0046] One or more first positioning members and one or more second positioning members may be provided. The present embodiment does not specifically limit the number of the first positioning members and the second positioning members.

[0047] Combination Figure 5 In some embodiments of the present disclosure, a mating groove 122 is provided at the end surface of the output end 120, and the mating groove 122 extends along the axial direction of the output end 120. A mating shaft 204 is provided at the first end of the extension shaft 200, and the mating shaft 204 extends along the axial direction of the extension shaft 200 and is plugged into and mated with the mating groove 122. The side wall of the mating shaft 204 contacts and fits with the inner wall of the mating groove 122.

[0048] The plug-in structure of the matching shaft 204 and the matching groove 122 is beneficial to increase the connection strength between the extension shaft 200 and the output end 120 and improve the stability.

[0049] Optionally, the mating shaft 204 is a spline shaft, and the mating groove 122 is a spline groove, so as to realize a spline connection between the output end 120 and the extension shaft 200 , and further avoid relative rotation between the magnetic fluid body 100 and the extension shaft 200 .

[0050] Combination Figure 7In some embodiments of the present disclosure, a second threaded hole (not shown in the figure) is provided at the second end of the extension shaft 200, and the second threaded hole extends along the axial direction of the extension shaft 200. The rear support assembly 400 includes a support member 410 and a threaded fixing member (not shown in the figure), and the support member 410 is provided with a countersunk hole 411, and the countersunk hole 411 extends along the axial direction of the extension shaft 200. In the axial direction of the extension shaft 200, the countersunk hole 411 is aligned with the second threaded hole. The threaded fixing member can be a bolt or a screw structure, and the threaded fixing member is provided along the axial direction of the extension shaft 200, and the threaded fixing member is penetrated in the countersunk hole 411. One end of the threaded fixing member is connected to the extension shaft 200 through the second threaded hole, and the threaded fixing member can fix the support member 410 on the extension shaft 200, so that the support member 410 can rotate synchronously with the extension shaft 200.

[0051] Optionally, the second threaded hole is eccentrically arranged on the extension shaft 200, and the countersunk hole 411 is eccentrically arranged on the support member 410, so that the axis of the threaded fixing member is misaligned with the axis of the extension shaft 200, which is beneficial to prevent relative rotation between the support member 410 and the extension shaft 200.

[0052] In some embodiments of the present disclosure, the support member 410 is provided with a blind hole 412, which is connected to the counterbore 411 and extends to the end of the support member 410 away from the counterbore 411. The second end of the extension shaft 200 is provided with a stepped groove 203, which is an annular groove arranged along the circumference of the extension shaft 200. The diameter of the extension shaft 200 at the position of the stepped groove 203 is equal to the inner diameter of the blind hole 412. The second end of the extension shaft 200 is plugged and matched with the support member 410 through the blind hole 412.

[0053] The rear section support assembly 400 also includes a support ring 420, which is sleeved on the outside of the extension shaft 200 and located in the stepped groove 203. One end of the support ring 420 abuts against the side wall of the stepped groove 203, and the other end abuts against the end of the rear section support assembly 400.

[0054] The support ring 420 and the threaded fixing member jointly limit the support member 410, so that the relative position of the support ring 420 and the extension shaft 200 is fixed. When there is a deviation in the relative position of the support member 410 and the carrier plate 700, the relative position of the support member 410 and the extension shaft 200 can be adjusted by replacing the support ring 420 with different lengths.

[0055] In some embodiments of the present disclosure, the rear support assembly 400 further includes a shock absorber (not shown in the figure), which is arranged outside the support member 410. The shock absorber can adopt an elastic annular structure, and the shock absorber can produce elastic deformation under pressure to achieve the purpose of shock absorption.

[0056] Optionally, the outer side of the support member 410 is provided with a plurality of positioning ring grooves, and the shock absorber cooperates with the positioning ring grooves. Specifically, the shock absorber can be arranged in the positioning ring groove, or a protrusion structure adapted to the positioning ring groove is arranged on the radial inner side of the shock absorber, and the protrusion structure is located in the positioning ring groove. The axial positioning of the shock absorber can be achieved by the cooperation between the shock absorber and the positioning ring groove. The number of shock absorbers can be one or more. When the number of shock absorbers is one, the shock absorber can cooperate with a plurality of positioning ring grooves. When the number of shock absorbers is more than one, each shock absorber can cooperate with one positioning ring groove.

[0057] Combination Figure 3 and Figure 4 In some embodiments of the present disclosure, the magnetic fluid assembly further includes a mounting member 500 and a guide wheel 600. The mounting member 500 is detachably connected to the magnetic fluid body 100, and the guide wheel 600 is rotatably connected to one end of the mounting member 500 near the rear support assembly 400.

[0058] Specifically, the extension direction of the mounting member 500 is parallel to the axial direction of the extension shaft 200, one end of the mounting member 500 is detachably connected to the side wall of the magnetic fluid body 100, and the other end is provided with a mounting groove and a mounting axis, the mounting groove passes through the mounting member 500 along the arrangement direction of the extension shaft 200 and the mounting member 500, the mounting axis is perpendicular to the axial direction of the extension shaft 200, and perpendicular to the arrangement direction of the extension shaft 200 and the mounting member 500, and the guide wheel 600 is located in the mounting groove and connected to the mounting axis.

[0059] Combination Figure 8 and Fig. 9 When the rear support assembly 400 cooperates with the groove on the carrier 700, the wheel surface of the guide wheel 600 abuts against the bottom of the groove on the carrier 700, thereby limiting the carrier 700 and correcting the deviation of the carrier 700 during its travel.

[0060] Optionally, the mounting member 500 has an adjustment hole 501, which penetrates the mounting member 500 in the radial direction of the extension shaft 200, and the adjustment hole 501 extends in the axial direction of the extension shaft 200, and a first threaded hole is provided on the side wall of the magnetic fluid body 100. The magnetic fluid assembly also includes an adjustment member 502, which is a structure such as a bolt or a screw, and the adjustment member 502 is penetrated in the adjustment hole 501 and connected to the magnetic fluid body 100 through the first threaded hole. The mounting member 500 and the magnetic fluid body 100 are detachably connected through the adjustment member 502. When the adjustment member 502 is loosened, the relative position between the mounting member 500 and the guide wheel 600 and the magnetic fluid assembly can be adjusted along the axial direction of the extension shaft 200 to adapt to the change of the cavity size and meet different working conditions.

[0061] Optionally, there are multiple adjusting holes 501 and multiple adjusting members 502, and the mounting member 500 is connected to the magnetic fluid body 100 through multiple adjusting members 502. The mounting method of multiple adjusting members 502 can prevent the mounting member 500 from rotating around the adjusting member 502, thereby increasing the stability of the structure.
