[0043] Typical embodiments that embody the features and advantages of the present invention will be described in detail in the following description. It should be understood that the present invention can have various changes in different embodiments without departing from the scope of the present invention, and the descriptions and illustrations therein are essentially used for illustration purposes rather than for limiting the present invention.

[0044] like Figures 1 to 6 As shown, this embodiment provides a ceramic bead threading device for use in electric heating tube processing equipment, which includes a workbench 1, a feeding mechanism 2, a first clamping mechanism 3, a first moving mechanism 4, a second clamping mechanism 5, a rotating cylinder 6 and a second moving mechanism 7.

[0045] The workbench 1 is installed on the frame of the electric heating tube processing equipment and serves as the main bearing body of the device.

[0046] The first clamping mechanism 3 includes a first clamping cylinder 31 and a first clamping arm 32. The first clamping arm 32 is mounted on the clamping claw of the first clamping cylinder 31 and is provided with an arc-shaped first positioning groove adapted to the shape of the large end 110 of the ceramic bead 100. The first clamping cylinder 31 drives the two first clamping arms 32 to close or move away, thereby clamping and releasing the large end 110 of the ceramic bead 100.

[0047] The first moving mechanism 4 is disposed on the workbench 1 and is in driving connection with the first clamping cylinder 31 , driving the first clamping arm 32 to reciprocate between the feeding mechanism 2 and the second clamping mechanism 5 .

[0048] The second clamping mechanism 5 includes a second clamping cylinder 51 and a clamping portion 52. The second clamping cylinder 51 is in transmission connection with the clamping portion 52, driving the second clamping arm 53 in the clamping portion 52 to close or move away, thereby clamping and releasing the small end 120 of the ceramic bead 100 without interfering with the first clamping arm 32 clamping the large end 110.

[0049] The rotary cylinder 6 is in driving connection with the clamping part 52, driving the clamping part 52 and the ceramic beads 100 in the second clamping arm 53 to rotate back and forth together. However, it can be understood that in other embodiments, a high-precision servo motor or stepper motor can also be used to drive the clamping part 52 to rotate.

[0050] The second moving mechanism 7 is disposed on the workbench 1 and is in driving connection with the rotary cylinder 6 to drive the rotating clamping portion 52 to approach or move away from the guide rod 200 of the electric heating tube.

[0051] The clamping part 52 is driven to rotate by the rotating cylinder 6, so that the porcelain bead 100 in the clamping part 52 also rotates. At the same time, the second moving mechanism 7 drives the rotating porcelain bead 100 forward, automatically correcting the position between the through hole of the porcelain bead 100 and the guide rod 200, making it easier for the guide rod 200 to penetrate into the porcelain bead 100, thereby greatly improving the production yield.

[0052] Specifically, continue to refer to Figure 3 The feeding mechanism 2 includes a vibration plate 21 and a feeding tube 22. The vibration plate 21 is installed on the workbench 1. One end of the feeding tube 22 is connected to the vibration plate 21, and the other end extends horizontally toward the first clamping mechanism 3. The ceramic beads 100 enter the feeding tube 22 after being vibrated by the vibration plate 21, and the large end 110 of the ceramic beads 100 faces outward. The ceramic beads 100 are arranged in order in the feeding tube 22 with the large end 110 facing outward through the vibration plate 21, which not only realizes automatic feeding, but also automatically arranges each ceramic bead 100 into the required feeding direction, reduces labor costs, and improves work efficiency.

[0053] The feeding mechanism 2 further includes a straight vibrator 23. The straight vibrator 23 is disposed on the workbench 1. The feeding tube 22 is connected to the upper surface of the straight vibrator 23. The straight vibrator 23 drives the feeding tube 22 and the porcelain beads 100 in the tube to vibrate, thereby accelerating the movement of the porcelain beads 100 in the tube and increasing the feeding speed.

[0054] Still reference Figure 3The first moving mechanism 4 includes a lifting cylinder 41, a linear cylinder 42, a first slide rail and a second slide rail 43. The piston rod of the lifting cylinder 41 is fixedly connected to the cylinder body of the first clamping cylinder 31, driving the first clamping cylinder 31 and the first clamping arm 32 to move up and down along the first slide rail, thereby driving the first clamping arm 32 to approach or move away from the second clamping arm 53 of the clamping portion 52. The linear cylinder 42 is installed on the workbench 1 through a bracket, and the slider of the linear cylinder 42 is fixedly connected to the cylinder body of the lifting cylinder 41, driving the lifting cylinder 41 to move along the second slide rail 43, thereby driving the first clamping arm 32 to reciprocate between the clamping portion 52 and the tube end of the feeding tube 22.

[0055] refer to Figures 7 to 13 The clamping portion 52 includes a second clamping arm 53 , a housing 54 and a push rod 55 .

[0056] Among them, Fig.10 As shown, a cavity is provided in the housing 54. The housing 54 includes a mounting seat 541 provided with the cavity and a cover 542 covering the open end of the cavity. The mounting seat 541 is composed of two cylinders with different diameters. A notch is provided on the mounting seat 541 and the cover 542 to avoid the movement of the second clamping arm 53. The output end of the rotary cylinder 6 is fixedly connected to the mounting seat 541, thereby driving the housing 54 and the internal structure thereof to rotate together.

[0057] One end of the second clamping arm 53 is inserted into the cavity, and the other end extends out of the cavity. Fig.11 As shown, one end of the second clamping arm 53 inserted in the cavity is provided with a first inclined surface 531 and a T-shaped groove 532 parallel to the first inclined surface 531, and the other end extending out of the cavity is in an "L" shape, and is provided with an arc-shaped second positioning groove adapted to the shape of the small end 120 of the porcelain bead 100, so as to firmly clamp the small end 120 of the porcelain bead 100. Preferably, in this embodiment, there are three second clamping arms 53, and the angle between adjacent clamping arms is 120°. The three second clamping arms 53 form a "Y" shape, so that no interference occurs when the first clamping arm 32 descends.

[0058] The left end of the push rod 55 is inserted into the cavity, and the right end extends out of the cavity. Fig.12 As shown, one end of the push rod 55 inserted in the cavity is provided with a second inclined surface 551 parallel to the first inclined surface 531 and a T-block 552 parallel to the second inclined surface 551 , and the other end extends out of the cavity and is connected to the piston rod of the second clamping cylinder 51 .

[0059] like Fig.13As shown, the T-block 552 is inserted into the T-slot 532, and the T-slot 532 and the T-block 552, the first inclined surface 531 and the second inclined surface 551 can slide relative to each other. When the piston rod of the second clamping cylinder 51 is extended, the second clamping arm 53 moves toward the outside along the second inclined surface 551, thereby releasing the porcelain bead 100; when the piston rod of the second clamping cylinder 51 is retracted, the second clamping arm 53 moves toward the center along the second inclined surface 551, thereby clamping the small head end 120 of the porcelain bead 100. The structure of the clamping part 52 of this embodiment is small and compact, and the clamping and placing action of the porcelain bead 100 is efficient and fast.

[0060] For reference Figure 6-8 , Fig.14 , Fig.15 The second clamping mechanism 5 also includes a connecting rod 56, a transfer block 57 and a connecting frame I 58. The right end of the connecting rod 56 is provided with an annular protrusion, and the left end is provided with an external thread. The end of the push rod 55 away from the cavity is provided with an internal thread that matches the external thread. Fig.14 As shown, the adapter block 57 is in the shape of a roller, and a receiving hole is provided inside thereof to cooperate with the annular protrusion. The connecting rod 56 passes through the adapter block 57 and is threadedly connected to the push rod 55. Fig.15 As shown, the connecting frame I58 is a hollow annular body, and one end is connected to the piston rod of the second clamping cylinder 51, and the other end is provided with a notch for avoiding the connecting rod 56. The above-mentioned adapter block 57 is located inside the connecting frame I58. When the rotary cylinder 6 drives the clamping part 52 to rotate, the connecting rod 56 threadedly connected to the push rod 55 also rotates together. Since the connecting frame I58 is in contact connection with the two end surfaces of the adapter block 57 and in rolling connection with the side surface of the adapter block 57, the connecting rod 56 will not generate obvious torque on the piston rod of the second clamping cylinder 51 when rotating, thereby extending the service life of the second clamping cylinder 51.

[0061] Continue to refer Figures 4 to 8 The second moving mechanism 7 includes a propulsion cylinder 71, a mounting plate 72 and a third slide rail 73. The cylinder body of the propulsion cylinder 71 is fixed on the workbench 1. The bottom surface of the mounting plate 72 is connected to the third slide rail 73 provided on the frame, and the right end is fixed to the piston rod of the propulsion cylinder 71, and expands and contracts with the piston rod of the propulsion cylinder 71. The above-mentioned rotary cylinder 6 is installed on this mounting plate 72, so the position accuracy during movement will be higher.

[0062] Still reference Figures 5 to 8The second moving mechanism 7 is also provided with a buffer assembly, which includes a connecting frame Ⅱ74, a compression spring 75 and a buffer tube 76. The right end of the buffer tube 76 is fixedly connected to the piston rod of the propulsion cylinder 71, and the left end is provided with an annular baffle. The connecting frame Ⅱ74 is fixedly connected to the upper surface of the mounting plate 72. The connecting frame Ⅱ74 is a hollow structure and has a notch at one end close to the buffer tube 76. One end of the buffer tube 76 provided with an annular baffle is inserted into the connecting frame Ⅱ74. One end of the compression spring 75 is connected to the annular baffle, and the other end is connected to the inner wall of the connecting frame Ⅱ74. After the porcelain bead 100 is inserted into the guide rod 200, when it touches the tube body, the compression spring 75 is compressed, thereby realizing the function of buffering and shock absorption.

[0063] Reference again Figure 6 , the second moving mechanism 7 also includes a vertical plate 77 and an adjusting screw 78. A longitudinal strip hole is provided on the vertical plate 77. The lower end of the vertical plate 77 is fixedly connected to the mounting plate 72, and the upper end is fixedly connected to the cylinder body of the rotating cylinder 6 through the strip hole to lift the rotating cylinder 6. The lower end of the adjusting screw 78 is threadedly connected to the mounting plate 72, and the upper end abuts against the bottom surface of the rotating cylinder 6. When facing electric heating tubes of different diameters, the height of the rotating cylinder 6 can be changed by screwing the adjusting screw 78, and then the rotating cylinder 6 is fixed to the vertical plate 77 using ordinary screws and the strip hole, which greatly improves the compatibility of the device.

[0064] Based on the above structural description of the device for threading porcelain beads 100, the working mode of the device is described in detail below in conjunction with the accompanying drawings:

[0065] Semi-finished electric heating tube 300( Fig.16 ) is fixed by the positioning mechanism, and the guide rod 200 faces the clamping part 52.

[0066] The vibrating plate 21 delivers the ceramic beads 100 into the feeding pipe 22 with the large end 110 facing outward, thus completing the feeding action.

[0067] The linear cylinder 42 drives the first clamping arm 32 to move above the tube end of the feed tube 22. The lifting cylinder 41 drives the first clamping arm 32 to descend to the tube end position, and the first clamping cylinder 31 drives the two first clamping arms 32 to close together to clamp the large end 110 of the ceramic bead 100 at the tube end. Then the lifting cylinder 41 drives the first clamping arm 32 to rise, and the linear cylinder 42 drives the first clamping arm 32 to move above the clamping portion 52.

[0068] The piston rod of the second clamping cylinder 51 extends, driving the connecting rod 56 and the push rod 55 to move forward, thereby driving the three second clamping arms 53 to open. The lifting cylinder 41 drives the first clamping arm 32 to descend to the center position of the three second clamping arms 53. Then the piston rod of the second clamping cylinder 51 retracts, driving the connecting rod 56 and the push rod 55 to move backward, thereby driving the three second clamping arms 53 to close, clamping the small end 120 of the ceramic bead 100, and completing the material removal action.

[0069] The piston rod of the push cylinder 71 extends, and the rotating cylinder 6 drives the clamping part 52 and the porcelain bead 100 thereon to rotate back and forth. The porcelain bead 100 rotates while approaching the guide rod 200, and finally the porcelain bead 100 is inserted into the guide rod 200, completing the feeding action. The process of inserting the porcelain bead 100 is now completed.

[0070] The piston rod of the second clamping cylinder 51 extends again, driving the three second clamping arms 53 to open and release the porcelain bead 100. The piston rod of the propulsion cylinder 71 retracts, driving the clamping part 52 to reset, waiting for the next time to wear the porcelain bead.

[0071] Although the present invention has been described with reference to the above typical embodiments, it should be understood that the terms used are illustrative and exemplary, rather than restrictive. Since the present invention can be implemented in a variety of forms without departing from the spirit or essence of the invention, it should be understood that the above embodiments are not limited to any of the foregoing details, but should be interpreted broadly within the spirit and scope defined by the appended claims, so all changes and modifications falling within the claims or their equivalents should be covered by the appended claims.
