Description

Technical Field

[0001] This utility model relates to the field of tooling and testing technology, and in particular to a tooling for testing the feeding action of a cooking machine. Background Technology

[0002] With the advent of the smart era, cooking machines are gradually entering people's daily lives, allowing them to enjoy delicious meals without having to cook themselves. When using a cooking machine, users need to place the chopped ingredients into the feeding mechanism. Upon receiving the feeding command, the corresponding drive component rotates the mechanism 180 degrees, and then the drive component pushes the push rod to open the door, allowing the ingredients to fall into the wok. Therefore, the drive component plays a crucial role in whether the cooking machine can complete the feeding action. How to verify whether the drive component's stroke is complete and in the optimal position has become a problem that the applicant urgently needs to solve. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a project testing fixture for inspecting the feeding action of a cooking machine, which can check whether the driving stroke of the driving component is in place and in the optimal position.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] This utility model provides a test fixture for inspecting the feeding action of a cooking machine, including a base frame. The base frame has push rod assemblies on both the front and rear sides. Each push rod assembly includes a mounting seat on the base frame, a push rod passing through the mounting seat, a latch on the push rod for abutting against the door panel, a reset spring in the mounting seat for resetting the push rod, and a detection component on the base frame for detecting when the push rod moves to the unlocked position under the drive of the driving component.

[0006] Preferably, the inspection fixture for testing the feeding action of the cooking machine also includes a reference reference for testing the width of the inner cavity space where the feeding mechanism is installed on the cooking machine.

[0007] Preferably, the reference reference members are disposed on the left and right sides of the base frame.

[0008] Preferably, the left and right sides of the base frame are respectively provided with a main slider and a slave slider, and the outer side plates of the main slider and the slave slider are protrusions extending toward the support frame for installing the feeding mechanism inside the cooking machine, and the protrusions serve as the reference reference parts.

[0009] Preferably, the detection component is one of a micro switch, a proximity switch, and a photoelectric switch disposed on the mounting base.

[0010] Preferably, the detection component is a photoelectric switch mounted on the base frame and used to detect whether the door panel is open, a weight is fixed to the door panel, and the base frame has a limiting cylinder to prevent the door panel from over-twisting.

[0011] Preferably, the base frame also has a bracket for mounting the photoelectric switch.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The project's testing fixture includes a base frame, with push rod assemblies on both the front and rear sides. Each push rod assembly includes a mounting base, a push rod, a latch, and a return spring. A testing component is mounted on the base frame. When the corresponding drive component inside the cooking machine receives the feeding signal, its core extends and pushes the push rod. The push rod moves within the mounting base. When the push rod reaches the unlocked position (the latch opens the door panel), it triggers the testing component, thus verifying the drive stroke of the drive component. The operation of the drive component used to open the door panel and feed material in the finished product, after testing by this fixture, fully meets the company's technical standards.

[0023] like Figures 1 to 7 As shown, this utility model provides a testing fixture for inspecting the feeding action of a cooking machine. The testing fixture includes a base frame 10, a push rod assembly 11, a testing component 13, and a reference datum 14, and can verify whether the drive stroke of the drive component 20 is complete and in the optimal position.

[0024] I. Base frame 10

[0025] The base frame 10 is horizontally suspended and supports components including the push-pull assembly and the door panel 12. The base frame 10 includes an outer frame with a rectangular outer contour. The outer frame is divided into a front frame, a rear frame, a left frame, and a right frame that are connected in sequence. Preferably, the base frame 10 is provided with four discharge ports. A crossbeam is connected between the inner sides of the left and right frames, and a longitudinal beam is provided between the crossbeam and the front and rear frames, respectively. The outer frame, the crossbeam, and the two longitudinal beams are connected to each other to form the four discharge ports.

[0026] The base frame 10 has a main slider 15 and a slave slider 16 on its left and right sides, respectively. The motor output shaft mounted on the cooking machine frame is connected to the main slider 15 via a rotating shaft sleeve 21, and the slave slider 16 is connected to another rotating shaft sleeve 21 mounted on the frame opposite to the motor. This detection fixture can be quickly installed inside the cooking machine via the main slider 15 and the slave slider 16.

[0027] By setting the main slider 15 and the slave slider 16, it is possible to detect whether the rotating sleeve 21 is fully fitted onto the motor output shaft. If the rotating sleeve 21 is not fully fitted onto the motor output shaft, the rotating sleeve 21 cannot be locked with the main slider 15 or the slave slider 16 by the elastic pin, and thus the feeding mechanism cannot be flipped.

[0028] II. Push Rod Assembly 11

[0029] The push-pull assembly is located on the front and rear sides of the base frame 10. The push rod assembly 11 includes a mounting base 111, a push rod 112, a latch 113, and a return spring 114. This utility model provides two specific assembly methods for the push-pull assembly.

[0030] 1. For example Figure 4 and Figure 5 As shown, the first assembly method of the push rod assembly 11

[0031] Mounting base 111 has a detachable limiting block 22 and a sealing cover 23. The limiting block 22 is a vertical plate. To improve the stability of the push rod 112 when it moves in a straight line, there are at least two limiting blocks 22 and they are spaced apart. Each limiting block 22 is provided with a through hole. All through holes are coaxially arranged, and the push rod 112 can move freely in the through hole.

[0032] The sleeve of the latch 113 is fixedly sleeved on the push rod 112. Preferably, in order to enhance the stability of the latch 113 during installation and movement, another positioning rod can be added to the side of the push rod 112, which is fixed to the limit block 22 and parallel to the push rod 112. Correspondingly, a positioning hole is opened on the sleeve, and the positioning rod passes through the positioning hole with a clearance fit.

[0033] The sealing cover 23 is a hollow elongated tube. Two sets of push rod assemblies 11 on the same side share a single return spring 114. The two ends of the return spring 114 are respectively sleeved on the push rod 112. The sealing cover 23 seals the return spring 114, preventing water and dust from entering and also preventing the intrusion of smoke or juices from the inner cavity during cooking. In addition, each of the two sets of push rod assemblies 11 on the same side can have a corresponding return spring 114 (not shown in the figure). The two return springs 114 face each other, with one end of the return spring 114 sleeved on the end of the corresponding push rod 112, and the other end of the return spring 114 abutting against the limiting block 22 set inside the sealing cover 23.

[0034] The limiting block 22 has a limiting effect on the movement of the latch 113. Preferably, for a wider door panel 12, one or more additional limiting blocks 22 can be set between the two limiting blocks 22 to improve the stability of the push rod 112 when it moves in a straight line. The limiting block 22 closest to the latch 113 can also limit the outward movement of the latch 113 (outward refers to the direction closer to the drive component 20). A sealing cover 23 can be set between two adjacent limiting blocks 22 on the outer side of the latch 113 to prevent smoke, juice or impurities in the inner cavity of the cooking machine from entering the gap between the push rod 112 and the limiting block 22, and to prevent the push rod 112 from being stuck by impurities.

[0035] 2. For example Figure 6 and Figure 7 As shown, the second assembly method of the push rod assembly 11

[0036] Mounting base 111 is mounted on base frame 10 and is a long cylindrical shape with a hollow channel inside. A limiting block 22 is located in the middle section of mounting base 111, and the cross-sectional shape of the limiting block 22 is the same as that of the middle section. The limiting block 22 has an axial through hole, and both ends of mounting base 111 also have axial through holes. The two ends of push rod 112 pass through one end of mounting base 111 and the axial through holes in limiting block 22, respectively, and can move freely. One end of push rod 112 protrudes from limiting block 22 and is screwed with a nut or inserted with a pin to limit the outward movement of push rod 112 during reset, preventing it from moving out of limiting block 22 and causing malfunction. Furthermore, this invention preferably integrates mounting base 111 and limiting block 22 into a single structure for easier assembly and disassembly.

[0037] The top of the mounting base 111 is provided with a channel communicating with the hollow channel. The sleeve of the latch 113 is inserted into the hollow channel through the corresponding channel. The hook of the latch 113 is connected to the outer end of the sleeve. Its cross-sectional shape is "7". The horizontal side of the hook rests on the top surface of the long strip of the channel. The vertical side of the hook faces the feed port. There is a distance between the hook and the channel that allows the latch 113 to move inward to completely offset from the locking tongue. A part of the inner end of the sleeve abuts against the inner wall of the hollow channel, so that the latch 113 is accurately positioned with the hollow channel and moves inward smoothly, while preventing the latch 113 from dislodging from the channel when it moves outward to reset.

[0038] The return spring 114 is placed between the inner end of the sleeve and the corresponding limiting block 22 and is sleeved on the push rod 112. In order for the latch 113 to move inward with the push rod 112, the push rod 112 is a stepped shaft. The step on the stepped shaft is located on the outer side of the sleeve. When the push rod 112 moves inward, the step pushes the latch 113 to move inward. When the push rod 112 is reset, the return spring 114 acts on the latch 113 to make the latch 113 also complete the reset.

[0039] III. Detection Component 13

[0040] The detection component 13 is mounted on the base frame 10 and is used to detect whether the push rod 112 moves to the unlocked position (the latch 113 opens the compartment door 12) under the drive of the drive component 20. The detection component 13 is mounted on the base frame 10 in the following two ways:

[0041] In the first case, the detection component 13 is one of a micro switch, a proximity switch, or a photoelectric switch mounted on the mounting base 111. The photoelectric switch is preferred in this invention. Specifically, the photoelectric switch is preferably positioned between the starting position (the position where the push rod 112 just triggers the latch 113 to open the door panel 12 during its movement) and the extreme position (the furthest position the push rod 112 continues to move after triggering the latch 113 to open the door panel 12). When the push rod 112 reaches this intermediate position, the photoelectric switch generates a sensor and transmits a data signal to the terminal system. The microcontroller of the terminal system determines whether the drive stroke of the drive component 20 is complete based on the data signal and displays the result on the terminal system's display screen, thereby realizing the detection of the drive component 20. The above-mentioned configuration can better ensure the stability of the drive component 20 being tested, and prevent the latch 113 from failing to open the door panel 12 when the drive component 20 ages and the thrust weakens. At the same time, it can also prevent the drive component 20 from having excessive thrust, causing the push rod 112 to collide and generate large noise during the feeding process of the cooking machine.

[0042] The second method involves a photoelectric switch, 13, mounted on the base frame 10, used to detect whether the door panel 12 is open. This method indirectly detects the drive component 20 by opening and closing the door panel 12. Specifically, when the drive component 20 is activated, it pushes the push rod 112, causing the latch 113 on the push rod 112 to disengage from the door panel 12, thus opening the door panel 12. At this time, the photoelectric switch generates a sensor and transmits a data signal to the terminal system. More specifically, a weight 17 simulating the weight of food is fixed to the door panel 12. The weight 17 causes the door panel 12 to disengage from the latch 113 and automatically flip. The base frame 10 has a limiting cylinder 18 to prevent the door panel 12 from over-flipping. The limiting cylinder 18 ensures that the door panel 12 can flip within a range of less than 180 degrees, facilitating automatic reset within this range. In order for the photoelectric switch to better sense the opening and closing of the door panel 12, this utility model preferably uses a through-beam photoelectric switch. The transmitter / receiver of the through-beam photoelectric switch is set on the bracket 19 of the base frame 10, and correspondingly, the receiver / transmitter of the through-beam photoelectric switch is set on the limiting cylinder 18 of the base frame 10.

[0043] IV. Reference Component 14

[0044] The reference reference 14 is used to detect the width of the inner cavity space of the feeding mechanism installed on the cooking machine, so as to prevent the feeding mechanism from shifting to the left or right during installation, which would affect the accuracy of detecting whether the driving stroke of the drive component 20 is sufficient to open the door plate 12. If the reference reference 14 is not set in the project detection fixture, when the project detection fixture is inserted into the cooking machine, there is a possibility of overall shifting to the left. In this case, the detection of the drive component 20 will be inaccurate. The reason is that even if the driving stroke of the drive component 20 does not meet the requirements (the stroke is too short), the door plate 12 will still be opened, and the detection on the other side will also have problems.

[0045] The setting method for reference component 14 is as follows:

[0046] The first type is to set the reference reference 14 on the left and right sides of the base frame 10.

[0047] The second type has a main slider 15 and a slave slider 16 on the left and right sides of the base frame 10, respectively. The outer side plates of the main slider 15 and the slave slider 16 are protrusions extending towards the support frame of the feeding mechanism installed in the cooking machine. These protrusions serve as reference reference parts 14.

[0048] 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.
