Description

Technical Field

[0001] The utility model relates to the field of pressure cooker assembly, in particular to an assembly fixture for an exhaust valve core of a pressure cooker. Background Art

[0002] At present, there are phenomena of air leakage or insufficient exhaust in pressure cookers. The main reasons are that when assembling, the exhaust valve core is not completely flush with the pot lid and is offset, resulting in inclination and air leakage. In addition, the valve core hole is blocked, the aperture is small, and the exhaust volume cannot meet the design requirements. The existing technology requires prior assembly, and then checking whether there is inclination, whether there is blockage, and whether the hole is small, resulting in low assembly efficiency. Moreover, this assembly method is prone to defective products and cannot ensure the consistency of product quality. Summary of the Utility Model

[0003] To solve the above problems, the present technical solution provides an assembly fixture for an exhaust valve core of a pressure cooker.

[0004] To achieve the above object, the present technical solution is as follows:

[0005] An assembly fixture for an exhaust valve core of a pressure cooker includes a base. A support portion for supporting the pot lid is provided on the base. The assembly fixture further includes a pneumatic chuck. A plurality of jaws for clamping or unlocking the exhaust valve core are circumferentially provided on the pneumatic chuck. A center between the plurality of jaws is provided with a pin passing through a through hole of the exhaust valve core for positioning and anti-blocking aperture detection.

[0006] In some embodiments, a sensor for detecting the pot lid is provided between the plurality of support portions.

[0007] In some embodiments, the support portion is adjustably connected to a bracket.

[0008] In some embodiments, the support portion is mounted on the bracket through a nut.

[0009] In some embodiments, the bracket is provided with an oval mounting hole.

[0010] The beneficial effects of the present application are as follows:

[0011] In this application, first, the inner hole of the exhaust valve core is passed through the positioning anti-blocking aperture detection needle, which is used to check whether the hole is blocked. Second, it is used to position the vertical position of the exhaust valve core. To ensure the complete assembly of the exhaust valve core and the pot lid later, then the pot lid is placed on the support part, and then the clamping jaws clamp the exhaust valve core. Since the upper end face of the clamping jaw is perpendicular to the outer circumference of the valve core, and the end face of the support part is flush with the end face of the clamping jaw, the valve core and the pot lid are in a flush state. Finally, the operator can lock it. Therefore, this fixture prevents the valve core from tilting during the assembly process. Moreover, there is no need to check the aperture size and whether the hole is blocked again later, which greatly improves the assembly efficiency and reduces the wear of the air screwdriver and other auxiliary fixtures, effectively solving the product performance and quality problems that customers have discovered and complained about many times during the use of such products: 1. The exhaust valve core is offset and leaks air poorly; 2. The hole is blocked and the exhaust is poor; 3. The aperture is too small and the exhaust is poor. It greatly improves the quality, reduces the number of customer complaints and the return rate, and reduces the manufacturing cost. Description of the Drawings

[0012] In order to more clearly illustrate the technical solutions in the embodiments of the present invention, the following briefly introduces the drawings required for the description of the embodiments.

[0013] Figure 1 It is a schematic structural diagram of an embodiment of the present invention. Detailed Embodiments

[0014] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the following further details the present invention with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0015] Please refer to Figure 1 As shown, an assembly fixture for a pressure cooker exhaust valve core includes a base 1. A support part 2 for supporting the pot lid is provided on the base 1. It also includes a pneumatic chuck 3. A plurality of clamping jaws 5 for clamping or unlocking the exhaust valve core 4 are circumferentially provided on the pneumatic chuck 3. An insertion pin 6 for positioning and anti-blocking aperture detection is provided at the center among the plurality of clamping jaws 5 and passes through the through hole of the exhaust valve core 4.

[0016] (One needle with multiple uses: 1. Positioning function; 2. Unclogging the inner hole to prevent blockage of the inner hole by foreign objects; 3. Detecting the size of the inner hole and ensuring effective exhaust of the designed exhaust volume during use). In this application, first, the inner hole of the exhaust valve core passes through the positioning anti-blocking aperture detection needle to check whether the hole is blocked and the aperture size. Secondly, it is used to position the vertical position of the exhaust valve core to ensure the complete assembly of the exhaust valve core and the pot lid. Then, the pot lid is placed on the support part, and then the clamping jaws clamp the exhaust valve core. Since the upper end surface of the clamping jaw abuts perpendicularly against the outer circumference of the valve core, and the end surface of the support part is flush with the end surface of the clamping jaw, the valve core and the pot lid are in a vertically flush state. Finally, the operator can lock it. Therefore, this fixture prevents the valve core from tilting during the assembly process. Moreover, there is no need to check the aperture size and whether the hole is blocked again later, which greatly improves the assembly efficiency and reduces the wear of the pneumatic screwdriver and other auxiliary fixtures, effectively solving the product performance and quality problems that customers have found and complained about many times during the use of such products: 1. Exhaust valve core offset and air leakage; 2. Inner hole blockage and poor exhaust; 3. Too small aperture and poor exhaust. It greatly improves the quality, reduces customer complaints and return rates, and reduces manufacturing costs.

[0017] In this embodiment, a sensor 7 for detecting the pot lid is provided between the plurality of support parts 2. When the pot lid is placed on the support part, the sensor detects a signal and sends a signal to the pneumatic chuck to drive the three clamping jaws to move closer to each other to clamp the valve core, which not only has an anti-mistake effect but also increases efficiency. After assembly, the clamping jaws are unlocked by pressing a button.

[0018] In this embodiment, the support part 2 is adjustably connected to the bracket 8 for adjusting the up and down position of the support part.

[0019] In this embodiment, the support part 2 is installed on the bracket 8 through a nut 9 for adjusting the up and down position of the support part.

[0020] In this embodiment, the bracket 8 is provided with an oval mounting hole 10 for adjustment according to the size of the pot lid.

[0021] The above are only the preferred embodiments of this application and are not used to limit the scope of implementation of this application. All those whose principles and basic structures are the same as or similar to this application are within the protection scope of this application.
