Description

Technical Field

[0001] This utility model relates to the field of shaft detection technology, and in particular to a tool for detecting the support shaft of a cooking machine furnace core. Background Technology

[0002] With the continuous development of technology, the emergence of intelligent cooking machines allows people to enjoy delicious food without having to cook themselves. During the cooking process, the wok unit automatically flips the wok body via a drive mechanism. The wok unit has a furnace core support shaft connected to its side. However, during use, the applicant discovered that the bending of the furnace core support shaft (referring to the bending deformation of the shaft system under external force or the influence of its own material properties) causes the wok body to wobble during flipping. Therefore, how to detect the bending of the furnace core support shaft has become an urgent problem for the applicant to solve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a tool for detecting the bending of the core support shaft of a cooking machine.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows: A tool for detecting the support shaft of a cooking machine furnace core includes a sleeve with a standard channel in the shape of a hollow cylinder. The top and bottom surfaces of the sleeve are open structures. A standard flat substrate is provided on the top surface of the sleeve. The standard flat substrate has a central through hole that is coaxial with the standard channel, penetrates the standard flat substrate, and is circular. The length of the sleeve is the same as the length of the main body section of the standard furnace core support shaft. The diameter of the central through hole is the same as the diameter of the bearing limiting ring of the light shield fixing platform provided on the main body section of the standard furnace core support shaft. The surface of the standard flat substrate is parallel to the surface of the light shield fixing platform on the standard furnace core support shaft.

[0005] Preferably, three openings are provided around the central through hole, and a wide notch and a narrow notch are provided on the peripheral wall of the sleeve, which extend axially and penetrate the sleeve. The wide notch is on the same side as two of the three openings, and the narrow notch is on the same side as the remaining opening.

[0006] Preferably, the inspection tool for testing the furnace core support shaft of the cooking machine further includes a cover, the cover having a hollow cavity adapted to the upper section of the standard furnace core support shaft.

[0007] Preferably, the top of the cover is provided with a through hole that communicates with the hollow cavity.

[0008] Preferably, the height of the standard planar substrate is the same as the height of the bearing limiting ring of the light-shielding plate fixing platform.

[0009] Preferably, a first notch is provided on one side of the standard planar substrate for observing the height of the bearing limiting ring of the furnace core support shaft under test.

[0010] Preferably, the cover has a second notch on its side for observing the upper section height of the furnace core support shaft to be tested.

[0011] Preferably, the bottom end face of the sleeve is provided with two positioning blocks that extend toward the channel axis in the diametrical direction and are connected to the peripheral wall of the sleeve.

[0012] Preferably, the two positioning blocks are of different sizes.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The inspection tool for testing the core support shaft of a cooking machine has a sleeve with a standard hollow cylindrical channel. The main body of the core support shaft to be tested is inserted into the standard channel of the sleeve. It can not only detect the length of the main body of the core support shaft, but also detect the coaxiality between the axis of the main body of the core support shaft and the reference axis of the standard channel of the sleeve. This can detect the shaft system bending of the core support shaft, thus effectively preventing the wok body from shaking during the flipping process due to the shaft system bending of the core support shaft. A standard planar base plate is provided on the top surface of the sleeve. The standard planar base plate has a central through hole that is coaxial with the standard channel and passes through the standard planar base plate. When the bearing limiting ring of the light shield fixing stage on the main body section of the standard furnace core support shaft is inserted into the central through hole, the plate surface of the standard planar base plate is parallel to the table surface of the light shield fixing stage on the standard furnace core support shaft. Therefore, the coaxiality of the axis of the bearing limiting ring under test and the reference axis of the central through hole of the standard planar base plate, and the parallelism of the table surface of the light shield fixing stage under test and the plate surface of the standard planar base plate can be detected to further discover the shaft system bending of the furnace core support shaft under test.

[0023] The cooking machine features automatic ingredient feeding, automatic cooking, automatic dish dispensing, and automatic pot washing. To achieve these functions, it is equipped with a station changing device, which includes six fixed stations: ingredient feeding, cooking, observation, dish dispensing, pot washing, and water emptying. The wok body rotates around the furnace core support shaft and stays at each of the six fixed stations for a set time as needed. The station changing device also includes a emitting plate, a receiving plate, a light-shielding plate, and a light sensor group corresponding to each of the six fixed stations. The emitting plate and the receiving plate are positioned opposite each other, and the light-shielding plate is rotatably positioned between them. The light sensor group includes a light emitting sensor and a light receiving sensor, with the light emitting sensor located on the emitting plate and the light receiving sensor on the receiving plate. The light-shielding plate has a light-transmitting hole. When the light-shielding plate rotates to the corresponding fixed station, the light-transmitting hole is positioned opposite the corresponding light emitting sensor and light receiving sensor, thus forming a light path between them.

[0024] like Figure 1 As shown, the furnace core support shaft is a shaft independently developed for cooking machines. It includes a main body section 1, an upper section 2, and a light shield mounting platform 3 set in the main body section 1. The light shield mounting platform 3 is provided with three screw holes 4 for fixing and installing the light shield.

[0025] During the production process, it is crucial to check whether the furnace core support shaft meets the standards (see the background art of this invention). Therefore, as... Figures 2 to 6 As shown, this utility model provides a tool for testing the support shaft of a cooking machine's furnace core. The tool includes a sleeve 5, a standard flat base plate 7, and a cover 12.

[0026] 1. Sleeve 5

[0027] The sleeve 5 has a hollow cylindrical standard channel 6, and its top surface 51 is open. The length of the sleeve 5 is the same as the length of the main body section 1 of the standard furnace core support shaft. Since the furnace core support shaft is located between the outer shell of the cooking machine and the wok, the accuracy of its length is critical. The main body section 1 of the furnace core support shaft to be tested is inserted into the standard channel 6 of the sleeve 5. If the main body section 1 of the furnace core support shaft to be tested exhibits shaft bending, it will not be able to be inserted into the standard channel 6 of the sleeve 5, or it will rub against the inner wall of the standard channel when rotating within it. Therefore, not only can the length of the main body section 1 of the furnace core support shaft to be tested be detected, but also the coaxiality of the axis of the main body section 1 of the furnace core support shaft to be tested with the reference axis of the standard channel 6 of the sleeve 5 can be detected to identify shaft bending of the furnace core support shaft. This effectively prevents the wok body from shaking during inversion due to shaft bending of the furnace core support shaft.

[0028] The sleeve 5 has a wide notch 10 and a narrow notch 11 extending axially and penetrating through the sleeve 5. The length of the main body section 1 can be observed through the wide notch 10 or the narrow notch 11. To observe whether its length is too long, observe whether the top of the main body section 1 is level with the top of the standard channel 6. To observe whether its length is too short, observe whether the bottom of the main body section 1 is level with the bottom of the standard channel 6.

[0029] The bottom end face 52 of the sleeve 5 is provided with two positioning blocks 17 extending axially towards the channel and serving as anti-foolproof features. Both positioning blocks 17 are connected to the peripheral wall 53 of the sleeve 5. The two positioning blocks 17 are of different sizes, corresponding to the positioning slots on both sides of the main body section 1. Specifically, one positioning block 17 is wider than the other. Furthermore, the bottom end face 52 of the sleeve 5 can be a closed structure or an open structure. This invention preferably adopts an open structure. The open structure of the bottom end face 52 not only facilitates observation of the positioning of the main body section 1 and the blocks, but also enhances the light transmittance inside the sleeve 5.

[0030] II. Standard Planar Substrate 7

[0031] The standard planar substrate 7 is positioned above the top surface 51 of the sleeve 5. The standard planar substrate 7 can be circular or square; the present invention preferably uses a square structure. The upper surface of the standard planar substrate 7 is flat, facilitating observation of the positional relationship between the light-shielding plate mounting platform 3 and the standard planar substrate 7. The standard planar substrate 7 has a circular central through-hole 14 that is coaxial with the standard channel 6 and extends through the standard planar substrate 7. The diameter of the central through-hole 14 is the same as the diameter of the bearing limiting ring 31 of the light-shielding plate fixing platform located on the main body section 1 of the standard furnace core support shaft. When the bearing limiting ring 31 of the light-shielding plate fixing stage on the main body section 1 of the standard furnace core support shaft is adapted to be inserted into the central through hole 14, the plate surface of the standard planar substrate 7 is parallel to the platform surface of the light-shielding plate fixing stage on the standard furnace core support shaft. Therefore, the coaxiality of the axis of the bearing limiting ring 31 under test and the reference axis of the central through hole 14 of the standard planar substrate 7, and the parallelism of the platform surface of the light-shielding plate fixing stage under test and the plate surface of the standard planar substrate 7 can be detected to further discover the shaft system bending of the furnace core support shaft under test.

[0032] Three openings 9 are provided around the central through hole 14, and the size and position of the three openings 9 are consistent with the hole position of the light shield. The wide notch 10 is on the same side as two of the three openings 9, and the narrow notch 11 is on the same side as the remaining opening 9. At this time, in addition to the functions mentioned above, the wide notch 10 and the narrow notch 11 also provide light transmission, which makes it easy to observe whether the setting position of the three screw holes 4 of the light shield mounting platform 3 is accurate, and avoids the light transmission hole from failing to form a light path between the light emitting sensor and the light receiving sensor due to assembly errors between the light shield and the light shield mounting platform 3.

[0033] The workstation changing device is installed inside the square box of the cooking machine and is connected to the drive motor or the sleeve shaft of the wok body via the furnace core support shaft. To prevent the square box from shifting and coming into contact with the workstation changing device when the furnace core support shaft rotates, thereby affecting the signal transmission between the transmitting sensor and the receiving sensor, a bearing limiting ring 31 is provided in the main body section 1. Due to the limited internal space of the square box, there are certain requirements for the height of the bearing limiting ring 31. Therefore, a first notch 15 is provided on one side of the standard planar substrate 7 for observing the height of the bearing limiting ring 31 of the furnace core support shaft under test. Preferably, the height of the standard planar substrate 7 is the same as the height of the bearing limiting ring 31 of the light shield fixing stage.

[0034] III. Cover 12

[0035] The cover 12 has a hollow cavity 13 that matches the upper section 2 of the furnace core support shaft. When the cover 12 is placed on the upper section 2 of the furnace core support shaft to be tested, if the upper section 1 of the furnace core support shaft to be tested has a axial bend, the cover 12 will not be able to close with the upper section 2, or it will rub against the upper section 2 when the cover 12 is rotated. Therefore, the length of the upper section 2 of the furnace core support shaft to be tested can also be detected, and the coaxiality of the axis of the upper section 2 of the furnace core support shaft to be tested with the reference axis of the hollow structure of the cover 12 can be detected to further discover the axial bend of the furnace core support shaft to be tested. Furthermore, the top of the cover 12 is provided with a through hole 14 that communicates with the hollow cavity 13. With the help of the through hole 14, the internal condition of the furnace core support shaft under test can be observed without removing the cover 12. The side of the cover 12 is provided with a second notch 16. The height of the upper section 2 of the furnace core support shaft under test can be observed through the second notch 16. If the height is too high, there is a gap between the cover 12 and the light shield mounting platform 3. If the height is too low, there is a gap between the top surface 51 of the upper section 2 and the top of the cover 12.

[0036] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model in any way. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the scope of the technical solution of the present utility model.
