Abstract
Description
Technical Field
[0001] This utility model belongs to the field of tooling equipment, specifically relating to a positioning tooling for a kettle. Background Technology
[0002] Commercially available kettles typically consist of a kettle body, a heating plate mounted at the bottom of the kettle body, and a handle mounted on the side of the kettle body. The heating plate is used to heat the liquid inside the kettle. Kettles have an anti-overflow structure near the handle. To enhance the aesthetics of transparent kettles, a silkscreen pattern is printed on the handle mounting area on the outer surface of the kettle body to conceal the anti-overflow structure.
[0003] However, current kettle positioning fixtures typically use three semi-circular positioning grooves to position the heating base, which in turn position the three riveting studs at the bottom of the heating base. Since the inner diameter of the positioning grooves is larger than the outer diameter of the riveting studs, the gap between the riveting studs and the inner wall of the positioning grooves provides a certain amount of rotational allowance for the heating base. This results in a positioning error due to the kettle's rotation. Furthermore, the subsequent manual placement and bonding of the kettle body onto the heating base also introduces errors. The cumulative positioning error from these two processes means that the through-holes on the heating base for inserting the temperature sensor and the through-holes on the kettle body for inserting the handle cannot be precisely aligned. This leads to misalignment of the silkscreen pattern during subsequent silkscreen printing, preventing the silkscreen from accurately covering the anti-overflow structure and resulting in a high product defect rate. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a positioning fixture for a kettle, so as to solve the problem that the mounting hole of the handle and the mounting hole of the temperature sensor of the heating plate cannot be accurately aligned during the assembly of the kettle.
[0005] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a positioning fixture for a kettle, the kettle including a kettle body and a heating base, the kettle body having a mounting hole for mounting a handle, and the heating base having a through hole for mounting a temperature sensor, the through hole being eccentrically positioned on the heating base. The positioning fixture includes a positioning seat and a positioning bracket. The positioning seat has a positioning post, which is inserted into the through hole to circumferentially limit the heating base placed on the positioning seat. The positioning bracket is installed on one side of the positioning seat and has a positioning protrusion, which is inserted into the mounting hole to circumferentially limit the kettle body embedded in the heating base, so that the central axes of the heating base, the through hole, and the mounting hole are coplanar. This technical solution has the following technical effects:
[0006] This invention features a positioning post on the positioning base and a positioning protrusion on the positioning bracket. During assembly of the heating base and the kettle body, the positioning post can be inserted into an eccentrically positioned through-hole to circumferentially limit the heating base placed on the positioning base, preventing rotation. The positioning protrusion can be inserted into a mounting hole on the side wall of the kettle body to circumferentially limit the kettle body embedded in the heating base. When the adhesive cures to bond and fix the heating base and kettle body, the through-hole on the heating base and the mounting hole on the kettle body remain on the same plane. This prevents misalignment of the mounting hole on the kettle body and the through-hole on the heating base due to rotational errors during assembly. In other words, it avoids assembly errors between the kettle body and the heating base, ensuring that the screen-printed pattern is centered on the handle mounting position during subsequent screen printing, accurately covering the anti-overflow structure and reducing product defect rates.
[0007] In the aforementioned positioning fixture for a kettle, the positioning seat includes a lower seat and an upper seat with positioning posts. The upper seat is installed above the lower seat to circumferentially limit the heating base placed above it. By setting the positioning seat in a structure where the lower seat and the upper seat are combined and installed, after the kettle body and the heating base are glued together, the upper seat can be detached from the lower seat, and the kettle body and the heating base can be detached from the lower seat together with the upper seat. Then, the kettle body, the heating base, and the upper seat are placed together on a turnover rack for the adhesive to cure. This reduces the difficulty of separating the heating base from the positioning seat when the heating base and the kettle body are not firmly glued.
[0008] In the aforementioned positioning fixture for a kettle, the bottom of the heating base is provided with multiple studs arranged around the central axis of the heating base. The upper seat is provided with insertion slots for inserting the studs, and the inner wall of the insertion slot away from the positioning post is provided with positioning ribs for abutting against the sides of the studs. The positioning ribs can abut against the side walls of the studs to fill the gap between the insertion slot and the stud, preventing the heating base from rotating. The insertion slot with the positioning ribs can cooperate with the positioning post to circumferentially limit the heating base at two different positions, resulting in better limiting effect and making the heating base more stable on the upper seat.
[0009] In the aforementioned positioning fixture for a kettle, the lower seat has a limiting hole, and the bottom of the upper seat has a limiting post that engages with the limiting hole. The limiting post is eccentrically positioned. By engaging the eccentrically positioned limiting post with the limiting hole, when the upper seat is mounted on the lower seat, the lower seat can circumferentially limit the upper seat through the engaging limiting post and limiting hole. This prevents the upper seat from rotating relative to the lower seat, which would affect the alignment of the through hole on the heating plate and the mounting hole on the kettle body, ensuring the accuracy of subsequent silkscreen printing.
[0010] In the aforementioned positioning fixture for a kettle, one side of the lower seat has an upward-opening mounting groove, into which the bottom of the positioning bracket is inserted. By installing the positioning bracket on the lower seat, the positioning bracket can both limit the circumferential movement of the kettle body and prevent the mounting bracket from detaching from the lower seat along with the upper seat when the kettle body and heating base are separated from the lower seat to cure the adhesive, thus facilitating operation. The insertion of the positioning bracket into the mounting groove on the lower seat makes the assembly and disassembly of the positioning bracket and the positioning seat more convenient, and facilitates the individual replacement of either the positioning bracket or the lower seat if either is damaged.
[0011] In the aforementioned positioning fixture for a kettle, the positioning bracket includes a fixed component and a movable component with a positioning protrusion. The fixed component is fixed to the positioning seat, and the movable component is rotatably connected to the top of the fixed component, so that the positioning protrusion can be inserted into or disengaged from the mounting hole by swinging. By setting the positioning bracket in a structure in which the movable component and the fixed component are rotatably connected, the movable component with the positioning protrusion can be swung to drive the positioning protrusion to be inserted into or disengaged from the mounting hole. When the movable component swings to a vertical position, the positioning protrusion is inserted into the mounting hole to circumferentially limit the kettle body, so that the mounting hole on the kettle body is aligned with the through hole on the heating base. When the end of the movable component with the positioning protrusion swings to a position that avoids the kettle body, the positioning protrusion is disengaged from the mounting hole of the kettle body, so that the kettle body can be installed on the heating base or the assembled kettle body and heating base can be removed together, avoiding the positioning protrusion from obstructing the placement or removal of the kettle body, and facilitating the assembly of the kettle body and the heating base.
[0012] In the aforementioned positioning fixture for a kettle, the positioning protrusion includes an mounting end fixed to a movable part and a limiting end for inserting into a mounting hole. The limiting end has a guide surface, which is inclined to avoid collisions between the positioning protrusion and the kettle body around the mounting hole during the swinging motion of the movable part. As the positioning protrusion swings with the movable part to insert into the mounting hole, the guide surface avoids collisions between the positioning protrusion and the kettle body during rotation, resulting in smoother insertion of the positioning protrusion into the mounting hole.
[0013] In the aforementioned positioning fixture for a kettle, limiting ribs are provided on both sides of the limiting end. When the positioning protrusion is inserted into the mounting hole, the two sides of the positioning protrusion abut against the inner wall of the mounting hole through the limiting ribs. The limiting ribs can fill the gap between the positioning protrusion and the inner wall of the mounting hole, allowing the positioning protrusion to stably abut against the inner wall of the mounting hole. This enables the positioning protrusion to stably limit the kettle body in the circumferential direction, ensuring that the mounting hole on the kettle body is precisely aligned with the through hole on the heating base for subsequent screen printing.
[0014] In the aforementioned positioning fixture for a kettle, the fixed part is provided with a stop protrusion. When the movable part rotates to the positioning position where the positioning protrusion and the mounting hole are inserted, the stop protrusion abuts against the movable part to prevent the movable part from continuing to rotate, thus avoiding excessive rotation of the movable part and impacting the kettle body. This keeps the positioning protrusion and the mounting hole in a stable insertion position, thereby providing circumferential stability for the kettle body.
[0015] In the aforementioned positioning fixture for a kettle, a magnetic component and a magnetic adsorption component are respectively embedded in the stop protrusion and the movable part. The magnetic component and the magnetic adsorption component engage magnetically to hold the movable part in the positioning position. When the movable part is rotated toward the stop protrusion, the magnetic component and the magnetic adsorption component engage magnetically, causing the movable part to rotate quickly to the positioning position where the positioning protrusion intersects with the mounting hole, thus holding the movable part in the positioning position and preventing the positioning protrusion from freely disengaging from the mounting hole. This ensures that the positioning protrusion on the movable part can stably limit the circumferential movement of the kettle body.
[0016] The features and advantages of this utility model will be disclosed in detail in the following specific embodiments and accompanying drawings. Attached Figure Description

[0028] This utility model proposes a positioning fixture for a kettle. The kettle includes a kettle body and a heating base. The kettle body has a mounting hole for mounting a handle, and the heating base has a through hole for mounting a temperature sensor. The through hole is eccentrically positioned on the heating base. The positioning fixture includes a positioning seat and a positioning bracket. The positioning seat has a positioning post that is inserted into the through hole to circumferentially limit the heating base placed on the positioning seat. The positioning bracket is installed on one side of the positioning seat and has a positioning protrusion that is inserted into the mounting hole to circumferentially limit the kettle body embedded in the heating base, so that the central axes of the heating base, the through hole, and the mounting hole are coplanar. This invention features a positioning post on the positioning base and a positioning protrusion on the positioning bracket. During assembly of the heating base and the kettle body, the positioning post can be inserted into an eccentrically positioned through-hole to circumferentially limit the heating base placed on the positioning base, preventing rotation. The positioning protrusion can be inserted into a mounting hole on the side wall of the kettle body to circumferentially limit the kettle body embedded in the heating base. When the adhesive cures to bond and fix the heating base and kettle body, the through-hole on the heating base and the mounting hole on the kettle body remain on the same plane. This prevents misalignment of the mounting hole on the kettle body and the through-hole on the heating base due to rotational errors during assembly. In other words, it avoids assembly errors between the kettle body and the heating base, ensuring that the screen-printed pattern is centered on the handle mounting position during subsequent screen printing, accurately covering the anti-overflow structure and reducing product defect rates.

[0034] Example 1:
[0035] A positioning fixture for a kettle, such as Figures 1 to 6As shown, the kettle 100 includes a kettle body 110 and a heating base 120. The heating base 120 is installed at the bottom of the kettle body 110 to form a kettle cavity 130 for holding liquid together with the kettle body 110. The heating base 120 is used to heat the liquid in the kettle cavity 130. A through hole 121 is provided on the heating base 120. The through hole 121 is eccentrically set on the heating base 120. A temperature sensor extends into the kettle cavity 130 through the through hole 121 to detect the temperature of the liquid in the kettle cavity 130. A handle is provided on the outer wall of the kettle body 110. The kettle body 110 is also provided with a mounting hole 111 that penetrates the side wall of the kettle body 110. The end of the handle is inserted into the mounting hole 111 to be installed on the outer wall of the kettle body 110. The positioning fixture includes a positioning seat 200 and a positioning bracket 300. A positioning post 221 is provided on the positioning seat 200. The positioning post 221 is located on the top of the positioning seat 200 and extends vertically upward. The positioning bracket 300 is installed on one side of the positioning seat 200 and a positioning protrusion 330 is provided on the positioning bracket 300.
[0036] When assembling the kettle body 110 and the heating base 120, first apply glue to the glue groove of the heating base 120, and then place the glued heating base 120 on the positioning seat 200. Align the positioning pin 221 with the through hole 121 so that the positioning pin 221 is inserted into the through hole 121. The positioning seat 200 can limit the horizontal movement of the heating base 120 placed on it, preventing the heating base 120 from moving horizontally. The positioning pin 221, inserted into the through hole 121, can limit the circumferential movement of the heating base 120 placed on the positioning seat 200, preventing the heating base 120 from rotating. Then, place the kettle body 110 on the heating base 120, with the bottom of the kettle body 110 embedded in the glue groove of the heating base 120. Next, insert the positioning protrusion 330 on the positioning bracket 300 into the mounting hole 111. The inner part is used to circumferentially limit the kettle body 110 embedded on the heating base 120, so that the central axis of the heating base 120, the central axis of the through hole 121 and the central axis of the mounting hole 111 are coplanar. That is, when the colloid is cured to bond and fix the heating base 120 and the kettle body 110, the plane formed by the central axis of the through hole 121 on the heating base 120 and the central axis of the mounting hole 111 on the kettle body 110 passes through the central axis of the heating base 120, so that the through hole 121 on the heating base 120 and the mounting hole 111 on the kettle body 110 are aligned.
[0037] This invention, by providing a positioning post 221 on the positioning base 200 and a positioning protrusion 330 on the positioning bracket 300, allows the heating base 120 and the kettle body 110 to be assembled. The positioning post 221 can be inserted into the eccentrically positioned through hole 121 to circumferentially limit the heating base 120 placed on the positioning base 200, preventing rotation. The positioning protrusion 330 can be inserted into the mounting hole 111 on the side wall of the kettle body 110 to circumferentially limit the kettle body 110 embedded in the heating base 120, allowing the colloid to solidify and support the heating base 120. When the heating base 120 and the kettle body 110 are bonded and fixed, the through hole 121 on the heating base 120 and the mounting hole 111 on the kettle body 110 are kept on the same plane. This prevents the mounting hole 111 on the kettle body 110 and the through hole 121 on the heating base 120 from being misaligned due to rotational errors during the assembly process. In other words, it avoids assembly errors between the kettle body 110 and the heating base 120, ensuring that the screen-printed pattern is centered on the handle mounting position during the later screen printing process, so as to accurately cover the anti-overflow structure and reduce the product defect rate.
[0038] like Figure 2 and Figure 4 As shown, the positioning base 200 includes an upper base 220 and a lower base 210. The upper base 220 and the lower base 210 are separately arranged. The upper base 220 is installed above the lower base 210. The upper base 220 is provided with an upwardly extending positioning post 221. When the heating base 120 is placed on the upper base 220, the positioning post 221 is inserted into the through hole 121 of the heating base 120 to limit the heating base 120 in the circumferential direction. By setting the positioning seat 200 into a structure where the upper seat 220 and the lower seat 210 are combined and installed, after the kettle body 110 and the heating base 120 are aligned and bonded, the upper seat 220 can be detached from the lower seat 210. The kettle body 110 and the heating base 120 can then be detached from the lower seat 210 together with the upper seat 220. Then, the kettle body 110, the heating base 120 and the upper seat 220 are placed together on a turnover rack for the adhesive to cure. This reduces the difficulty of separating the heating base 120 from the positioning seat 200 when the heating base 120 and the kettle body 110 are not firmly bonded.
[0039] Multiple studs 122 are provided at the bottom of the heating base 120, and the studs 122 are arranged around the central axis of the heating base 120. The upper seat 220 is provided with insertion slots 222 for inserting the studs 122. When the heating base 120 is placed on the upper seat 220, each stud 122 is inserted into its corresponding insertion slot 222. Figure 3As shown, a positioning rib 223 is provided in the insertion groove 222 away from the positioning post 221. The positioning rib 223 is provided on the inner wall of the insertion groove 222 to abut against the outer wall of the stud 122. The positioning rib 223 can fill the gap between the insertion groove 222 and the stud 122 by abutting against the outer wall of the stud 122, thus preventing the heating base 120 from rotating. The insertion groove 222 with the positioning rib 223 can cooperate with the positioning post 221 to circumferentially limit the two different positions of the heating base 120, resulting in a better limiting effect and making the heating base 120 more stable on the upper seat 220.
[0040] like Figure 4 As shown, in this embodiment, a limiting hole 211 is provided on the lower seat 210, and a limiting post 224 is provided at the bottom of the upper seat 220. The limiting post 224 is eccentrically positioned. When the upper seat 220 is installed on the lower seat 210, the limiting post 224 is inserted into the limiting hole 211 to engage with it. By engaging with the limiting hole 211 through the eccentrically positioned limiting post 224, when the upper seat 220 is installed on the lower seat 210, the lower seat 210 can limit the upper seat 220 circumferentially through the interlocking limiting post 224 and the limiting hole 211, preventing the upper seat 220 from rotating relative to the lower seat 210 and affecting the alignment of the through hole 121 on the heating base 120 and the mounting hole 111 on the kettle body 110, thus ensuring the accuracy of the subsequent screen printing position.
[0041] In this embodiment, as Figure 4 As shown, the lower seat 210 has an upward-opening mounting groove 212 on one side. The bottom of the positioning bracket 300 is inserted into the mounting groove 212. By installing the positioning bracket 300 on the lower seat 210, the positioning bracket 300 can limit the circumferential movement of the kettle body 110. At the same time, when the kettle body 110 and the heating base 120 are detached from the lower seat 210 along with the upper seat 220 to cure the adhesive, the mounting bracket will not detach from the lower seat 210 along with the upper seat 220, which is convenient for operation. The positioning bracket 300 is inserted into the mounting groove 212 on the lower seat 210, which makes the disassembly and assembly of the positioning bracket 300 and the positioning seat 200 more convenient. When the positioning bracket 300 or the lower seat 210 is damaged, it is convenient to replace them separately. Preferably, a plurality of longitudinally extending strip-shaped ribs 2121 are provided on the inner wall of the mounting groove 212. The strip-shaped ribs 2121 can fill the gap between the side wall of the mounting bracket and the inner wall of the mounting groove 212, making the insertion between the two tighter and preventing the mounting bracket from shaking.
[0042] In this embodiment, the positioning bracket 300 includes a fixing member 310 and a movable member 320. The bottom of the fixing member 310 is inserted into the mounting groove 212 to fix it on the positioning seat 200. The movable member 320 is rotatably connected to the top of the fixing member 310 via a horizontally arranged rotating shaft 313. A positioning protrusion 330 is provided on the movable member 320. When the end of the movable member 320 with the positioning protrusion 330 swings up and down, the positioning protrusion 330 swings together with the movable member 320. By setting the positioning bracket 300 in a structure in which the movable member 320 and the fixing member 310 are rotatably connected, the movable member 320 with the positioning protrusion 330 can swing to drive the positioning protrusion 330 to be inserted into or disengaged from the mounting hole 111. Figure 2 As shown, when the movable part 320 swings to a vertical position, the positioning protrusion 330 is inserted into the mounting hole 111 to circumferentially limit the kettle body 110, so that the mounting hole 111 on the kettle body 110 is aligned with the through hole 121 on the heating base 120. Figure 6 As shown, when the end of the movable part 320 with the positioning protrusion 330 swings to a position that avoids the pot body 110, the positioning protrusion 330 is disengaged from the mounting hole 111 of the pot body 110. The pot body 110 can be installed on the heating base 120 or the assembled pot body 110 and the heating base 120 can be removed together. This avoids the positioning protrusion 330 from obstructing the placement or removal of the pot body 110, and facilitates the assembly of the pot body 110 and the heating base 120.
[0043] like Figure 3As shown, in this embodiment, the positioning protrusion 330 is vertically disposed on the movable member 320, with its two ends being a mounting end 331 fixed on the movable member 320 and a limiting end 332 away from the movable member 320, respectively. When the movable member 320 swings to a vertical state, the limiting end 332 is horizontally inserted into the mounting hole 111 to circumferentially limit the pot body 110. A guide surface 3321 is provided on the limiting end 332. The guide surface 3321 is inclined around the central axis of the limiting end 332, so that... The axial section of the portion of the limiting end 332 with guide surface 3321 gradually increases from the side away from the movable part 320 toward the movable part 320. As a result, during the process of the positioning protrusion 330 swinging with the movable part 320 to insert into the mounting hole 111, the guide surface 3321 can avoid the pot body 110 around the mounting hole 111, preventing the positioning protrusion 330 from colliding with the pot body 110 during rotation, making the insertion of the positioning protrusion 330 into the mounting hole 111 smoother. Preferably, the limiting end 332 is further provided with limiting ribs 333 on both sides. The limiting ribs 333 extend along the central axis of the limiting end 332 on the outer side wall of the limiting end 332. When the positioning protrusion 330 is inserted into the mounting hole 111, the two sides of the positioning protrusion 330 abut against the inner wall of the mounting hole 111 through the limiting ribs 333. The limiting ribs 333 can fill the gap between the positioning protrusion 330 and the inner wall of the mounting hole 111, so that the positioning protrusion 330 can stably abut against the inner wall of the mounting hole 111. This allows the positioning protrusion 330 to stably limit the circumferential position of the kettle body 110, ensuring that the mounting hole 111 on the kettle body 110 is precisely aligned with the through hole 121 on the heating base 120 for subsequent screen printing.
[0044] In this embodiment, a stop protrusion 311 is provided on the fixing member 310, such as... Figure 2 As shown, when the movable part 320 rotates to the vertical position, it is positioned at a fixed position. At this time, the stop protrusion 311 abuts against the movable part 320 to prevent it from continuing to rotate towards the pot body 110, thus avoiding excessive rotation and impact with the pot body 110. This ensures that the positioning protrusion 330 and the mounting hole 111 remain in a stable insertion position, providing circumferential stability for the pot body 110. Figure 5 As shown, in this embodiment, a first limiting groove 314 is provided on the stop protrusion 311, and a magnetic component 312 is embedded in the first limiting groove 314. A second limiting groove 322 is provided on the movable component 320, and a magnetic adsorption component 321 is embedded in the second limiting groove 322. When the movable component 320 is rotated toward the stop protrusion 311, as... Figure 2As shown, the magnetic component 312 and the magnetic adsorption component 321 can magnetically engage, allowing the movable component 320 to quickly rotate to the positioning position where the positioning protrusion 330 engages with the mounting hole 111. This positions the movable component 320 in the positioning position, preventing the positioning protrusion 330 from freely detaching from the mounting hole 111 and ensuring that the positioning protrusion 330 on the movable component 320 can stably limit the circumferential movement of the kettle body 110. Preferably, the openings of the first limiting groove 314 and the second limiting groove 322 face the same side, facilitating the installation of the magnetic component 312 and the magnetic adsorption component 321 while preventing the magnetic component 312 from detaching from the first limiting groove 314 or the magnetic adsorption component 321 from detaching from the second limiting groove 322 due to strong magnetic attraction between them. Of course, it is understood that the magnetic adsorption component 321 in this embodiment can be a magnet with opposite poles to the magnetic component 312, or it can be a metal component composed of iron, cobalt, nickel, or their alloys that magnetically attracts a magnet. In another embodiment, the mounting positions of the magnetic component and the magnetic adsorption component can also be interchanged.
[0045] Example 2:
[0046] The difference between this embodiment and embodiment one is that in this embodiment, the positioning bracket is horizontally inserted into one side of the lower seat. When the positioning bracket is horizontally inserted into the lower seat, the positioning protrusion on the positioning bracket is inserted into the mounting hole. When the positioning bracket is horizontally disengaged from the lower seat, the positioning protrusion on the positioning bracket is disengaged from the mounting hole.
