Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarette components, in particular to a clamping ring mounting fixture for a heating tube. Background Art

[0002] E-cigarettes primarily consist of four components: e-liquid (containing nicotine, flavoring, and the solvent propylene glycol), a heating system (including the heating tube), a power supply, and a filter. Through heating and atomization, smokers produce an aerosol with a specific aroma. Currently, the heating tube of an e-cigarette requires a retaining ring during assembly to ensure a tight seal. This retaining ring is typically installed using a manual press, which lacks precise positioning and can easily over-press the heating tube, causing the retaining ring to be excessively pressed into the tube and potentially causing deformation and damage.

Therefore, it should not be construed as a limitation to the present application. The terms "first" and "second" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. That is, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In addition, unless otherwise specified, the meaning of "a plurality" is two or more.

[0028] As Figures 1-4 shown, the clamping ring installation jig for the heating tube of the embodiment of the present utility model includes a base 1, a first positioning block 2, a driving assembly 3, and a measuring assembly 4.

[0029] The first positioning 2 block is installed on the base 1. The upper surface of the first positioning block 2 has a positioning groove 21 for positioning the heating tube 5. A through hole 22 is provided at the lower part of the first positioning block 2 and extends along the horizontal direction X.

[0030] The driving assembly 3 is arranged on the base 1 and is disposed opposite to the first positioning block 2. The driving assembly 3 includes a cylinder 31, a slider 32 connected to the power output end of the cylinder 31, a push rod 33 disposed on the side of the slider 32 away from the cylinder 31, and a limiting rod 34. The push rod 33 is disposed on the limiting rod 34. The push rod 33 is configured to move in the direction close to the heating tube 5 and press the clamping ring 6 into the heating tube 5. The limiting rod 34 is configured to move in the through hole 22 along the horizontal direction X. The cylinder 31 can drive the push rod 33 and the limiting rod 34 to move along the horizontal direction X.

[0031] The measuring assembly 4 is arranged on the side of the first positioning block 2 away from the driving assembly 3. The measuring assembly 4 includes a micrometer 41 and a fixing block 42. The fixing block 42 is fixed on the base 1. The micrometer 41 includes a measuring end 41a and a micrometer screw 41b installed on the measuring end 41a. The measuring end 41a is fixed on the side of the fixing block 42 away from the first positioning block 2. The measuring end 41a is configured to adjust the micrometer screw 41b to move in the through hole 22 along the horizontal direction X through the fixing block 42. Among them, the micrometer 41 adopts the existing structure of the micrometer 41, but the frame needs to be removed, which is convenient for installation and use.

[0032] In this embodiment, when the clamping ring 6 is pressed into the heating tube 5 by the push rod 33, one end of the micrometer screw 41b abuts against one end of the limiting rod 34 in the through hole 22. Therefore, by adjusting the position of the micrometer screw 41b in the through hole 22 through the measuring end 41a, the stroke of the push rod 33 can be adjusted.

[0033] During operation, the snap ring 6 is pre-installed at one end of the heating tube 5. At this time, the snap ring 6 is not tightly clamped in the heating tube 5. Then, the heating tube 5 is installed in the positioning groove 21 of the first positioning block 2. The air cylinder 31 is activated to drive the push rod 33 and the limiting rod 34 to move along the horizontal direction X, so that the snap ring 6 is tightly pressed in the heating tube 5. At this time, one end of the micrometer screw 41b abuts against one end of the limiting rod 34 in the through hole 22. By adjusting the position of the micrometer screw 41b in the through hole 22 through the measuring end 41a, the stroke of the push rod 33 can be adjusted, so as to accurately press the snap ring 6 into the heating tube 5 and avoid damaging the heating tube 5.

[0034] As Figure 3 shown, in one embodiment, the snap ring installation fixture for the heating tube further includes a foot switch 7, and the air cylinder 31 is connected to the air source through the foot switch 7. By stepping on the foot switch 7, the operation of the air cylinder 31 can be controlled, thus not interfering with the work of the hand.

[0035] As Figure 1 and 4 shown, in one embodiment, the heating tube 5 includes a first section 51 and a second section 52. The diameter of the second section 52 is smaller than that of the first section 51. The first section 51 is installed in the positioning groove 21 of the first positioning block 2, and the second section 52 extends out of the positioning groove 21.

[0036] Optionally, the snap ring installation fixture for the heating tube further includes a second positioning block 8. The second positioning block 8 is installed on the side of the first positioning block 2 away from the driving assembly 3. The second positioning block 8 abuts against the end of the first section 51. The upper surface of the second positioning block 8 has a slot 81. The width of the slot 81 is smaller than the diameter of the first section 51 and larger than the diameter of the second section 52. The second section 52 is arranged in the slot 81 and one end extends out of the slot 81. By providing the second positioning block 8, when the heating tube 5 is subjected to the thrust of the push rod 33, it will not move in the positioning groove 21.

[0037] Optionally, the snap ring installation fixture for the heating tube further includes a third positioning block 9. The third positioning block 9 is installed on the side of the first positioning block 2 close to the driving assembly 3. The upper part of the third positioning block 9 has a through hole 91, and one end of the push rod 33 passes through the through hole 91. This keeps the moving position of the push rod 33 stable.

[0038] As Figure 1 shown, in one embodiment, the driving assembly 3 further includes a sliding seat 35. The sliding seat 35 is installed on the base 1, and the sliding seat 35 has a sliding groove 351. The slider 32 is slidably installed in the sliding groove 351. By providing the sliding seat 35, the movement of the slider 32 is kept stable.

[0039] Specifically, the shape of the slider 32 is adapted to the shape of the sliding groove 351, and the cross-section perpendicular to the horizontal direction X is in a "convex" shape. This enables the slider 32 to only move along the horizontal direction X and prevents it from slipping off in the vertical direction.

[0040] In one embodiment, the driving assembly 3 further includes a guiding block 36. The guiding block 36 is installed on the base 1. The guiding block 36 is provided with a guiding hole extending along the horizontal direction X, and the guiding hole is configured to allow the limiting rod 34 to pass through. The limiting rod 34 passing through the guiding hole makes the movement of the limiting rod 34 stable.

[0041] In one embodiment, the driving assembly 3 further includes a fixing plate 37. The fixing plate 37 is fixed to the base 1, and the side surface of the fixing plate 37 is fixedly connected to the end of the air cylinder 31 away from the slider 32. The fixing plate 37 makes the installation structure of the air cylinder 31 stable.

[0042] In one embodiment, the axial direction of the push rod 33 coincides with the axial direction of the heating tube 5. This enables the push rod 33 to accurately apply a thrust to the end of the heating tube 5, thereby pressing the snap ring 6 into the heating tube 5.

[0043] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and replacements can be made, and these improvements and replacements should also be regarded as the protection scope of the present invention.
