[0041] Example 1

[0042] See also Figures 1 to 5 , is a powder filling tooling jig for a heating tube as embodiment 1 of the utility model, used for filling magnesium oxide powder into the interior of the heating tube, comprising a base 10, a positioning seat 20, a first fixing member 30, a plug 40, and a powder filling sleeve 50, wherein the positioning seat 20 is arranged on the base 10; the first fixing member 30 is arranged on the base 10, and is used to fix or restrict the heating tube on the base 10; the plug 40 is detachably arranged at one end of the heating tube and prevents magnesium oxide powder from falling out; the powder filling sleeve 50 is detachably arranged at the other end of the heating tube and is used to fill magnesium oxide powder into the interior of the heating tube. The powder filling tooling jig of the utility model, by arranging the plug 40 under the heating tube to prevent magnesium oxide powder from falling out, cooperates with the powder filling sleeve 50 to facilitate the rapid filling of powder into the heating tube, thus filling the gap of the current lack of powder filling for small heating tubes.

[0043] Please refer to Figure 1 The positioning seat 20 is detachably arranged on the base 10. Specifically, the positioning seat 20 is locked on the base 10 by two bolts to achieve detachable connection. Since it is suitable for the powder filling of heating tubes with different outer diameters, the positioning seat 20 is detachable. When it is necessary to fill powder for heating tubes with different outer diameters, the bolts can be loosened to achieve rapid replacement of the positioning seat 20. At the same time, in order to adapt to wires of different lengths and different models, a plurality of scale lines 13 are also arranged on the base 10. The scale can be used to assist in positioning, further improving the applicability of the powder filling tool.

[0044] Please refer to Figure 3 The upper end surface of the positioning seat 20 is provided with a first groove 21 for embedding the outer wall of the heating tube, and the positioning seat 20 is detachable. The sizes of the first groove 21 corresponding to different types of heating tubes are different. The size of the first groove 21 is set according to the actual heating tube model and corresponds to different scale lines 13.

[0045] The heating tube of the utility model is hollow inside, and openings are set at both ends. A magnesium oxide tube is set inside the heating tube, and a heating wire is set inside the magnesium oxide tube. Wires are connected to both ends of the heating wire. Magnesium oxide powder is filled between the heating tube and the magnesium oxide tube, and inside the magnesium oxide tube. Therefore, when filling, a plug 40 needs to be set at one end. Since the inner diameter of the heating tube is small, the powder filling operation is facilitated by setting a powder filling sleeve 50. Optionally, the outer diameter range of the heating tube is 2.5mm-5mm, and the wall thickness is 0.15-0.25mm. Before filling with magnesium oxide powder, the outer wall of the heating tube is cylindrical, and a groove matching the outer wall of the heating tube is set on the positioning seat 20.

[0046] Please refer to Figure 1 The base 10 is provided with a second groove 11 for avoiding the wire, and the base 10 is also provided with an avoidance groove 12 for avoiding the plug 40 and the powder filling sleeve 50. The second groove 11 is adapted to the outer side of the wire, and the diameter can be slightly larger than the outer diameter of the wire. After the wire is embedded in the second groove 11, the second groove 11 will protrude, so that the fixing part is fixed on the outer wall of the wire.

[0047] Please refer to Figure 1 The first fixing members 30 are provided with three pieces, and all of them are fixedly provided on the base 10, and are used to fix the outer wall of the heating tube and the outer wall of the wire, and can also assist in centering the heating tube and the wire. The first fixing member 30 adopts a quick clamp, and is directly fixedly provided on the base 10. The specific structure and fixing method of the quick clamp are all prior art, and will not be described in detail.

[0048] Please refer to Figure 1 , 4 The powder filling tooling fixture also includes a buckle 60 for the wire to pass through. After the buckle 60 restricts the wire, the wire is more accurately restricted in the magnesium oxide tube, and the wire is kept at the center line position of the magnesium oxide tube as much as possible. The buckle 60 is fixed or detachably arranged on the base 10, and can be specifically locked by multiple bolts so that the buckle 60 can be detachably arranged on the base 10. The buckle 60 is also provided with a tapered hole 61 for the wire to pass through. After the wire passes through the buckle 60, two first fixing members 30 for clamping the wire are matched, so as to better restrict or fix the wire on the base 10 and avoid the deviation of the heating wire.

[0049] Please refer to Figure 5 The plug 40 is sleeved on one end of the heating tube, and a hole is set in the middle for the wire to pass through. The powder filling sleeve 50 is hollow inside, and is adapted to be sleeved on the outer wall of the heating tube at the bottom. The upper diameter of the powder filling sleeve 50 is larger than the diameter of the lower opening, and the space inside the powder filling sleeve 50 can meet the amount of magnesium oxide powder filled at one time. It only takes one time to fill the magnesium oxide tube to achieve complete filling, so as to facilitate more efficient filling.

[0050] Example 2

The frame 70 includes a support seat 71 arranged around and used to support the powder filling jig, and a second fixing member 72 arranged on the frame 70 and used to fix or limit the powder filling jig; the cross section of the support seat 71 perpendicular to the long side is in an "L" shape, so that a slot is formed between the support seat 71 and the frame 70 to prevent the base 10 from being stuck. In combination with the second fixing member 72, the base 10 can be well fixed around the frame 70. The second fixing member 72 adopts a quick clamp to facilitate the quick clamping of the base 10. The second fixing member 72 is arranged above the supporting seat 71 to better fix the powder filling tooling fixture. A plurality of bases 10 can be arranged around the frame 70 to realize powder filling of a plurality of heating tubes, thereby greatly improving the filling efficiency.

[0052] The working principle of the powder filling equipment of this utility model is as follows:

[0053] First, install the heating tube: put the plug 40 on one end of the hollow heating tube, and set the powder filling sleeve 50 on the other end, then install the hollow heating tube on the positioning seat 20 through the first fixing member 30, put the magnesium oxide tube into the heating tube, and prevent it from falling under the action of the plug 40, and then pass the heating wire with the wire through the powder filling sleeve 50, the magnesium oxide tube and the plug 40 in turn, align the corresponding scale line 13, the heating wire is accurately located in the magnesium oxide tube, and finally put the magnesium oxide powder into the powder filling sleeve 50;

[0054] Second, place the installed base 10 on the support base 71, then fix the base 10 by the second fixing member 72, start the oscillation device, and the filling is completed after the specified time.

[0055] To sum up, the powder filling tool of the utility model first centers the wire through the buckle and the first fixing seat, and then assists in powder filling through the plug. Specifically, a plug is arranged under the heating tube to prevent the magnesium oxide powder from falling out, and at the same time, it cooperates with the powder filling sleeve to facilitate the rapid filling of the heating tube with powder, which fills the gap in the current lack of powder filling for small heating tubes. The powder filling tool of the utility model is matched with the powder filling equipment and the powder filling sleeve to realize one-time filling. After the vibration device vibrates, the powder filling operation can be completed.
