Description

Technical Field

[0001] This utility model relates to the field of oxygen-sensing ceramic processing technology, and in particular to an auxiliary tooling for pressing oxygen-sensing ceramics. Background Technology

[0002] An oxygen sensor is primarily used to determine whether there is excess oxygen in the exhaust gas after engine combustion, i.e., the oxygen content. This oxygen content is converted into a voltage signal and transmitted to the engine computer, enabling the engine to achieve closed-loop control with an excess air coefficient as the target. This ensures that the three-way catalytic converter has maximum conversion efficiency for the three pollutants in the exhaust gas: hydrocarbons (HC), carbon monoxide (CO), and nitrogen oxides (NOx), maximizing the conversion and purification of emission pollutants. If the oxygen sensor malfunctions, the electronic fuel injection system's computer will not receive information about the oxygen concentration in the exhaust pipe, thus failing to perform feedback control of the air-fuel ratio. This will increase engine fuel consumption and exhaust pollution, and cause engine problems such as unstable idling, misfires, and engine flare.

[0003] When pressing oxygen sensors, the cross-sectional area of ​​the pressing groove for the oxygen sensing ceramic is generally larger than the outer wall of the oxygen sensing ceramic. To prevent uneven stress during the pressing process from damaging the ceramic layer, longitudinal stability needs to be maintained. A common method is lateral clamping, but this method is prone to lateral damage to the ceramic layer. Since the oxygen sensing ceramic structure has a connecting nut, an auxiliary tooling can be designed to work with the connecting nut for clamping. This will maintain the stability of the oxygen sensing ceramic during the pressing process and prevent displacement, which could lead to damage to the oxygen sensing ceramic. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide an auxiliary tooling for pressing oxygen sensing ceramics, which can solve the problem that the oxygen sensing ceramic layer is easily damaged during the pressing process of traditional oxygen sensing ceramics due to displacement.

[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is: an auxiliary tooling for pressing oxygen-sensing ceramics, the innovation of which is: it includes an oxygen-sensing ceramic rotary table and an oxygen-sensing ceramic positioning and locking module; the oxygen-sensing ceramic positioning and locking module is set on the oxygen-sensing ceramic rotary table. A pressing device for pressing oxygen sensing ceramics is provided above one side of the oxygen sensing ceramic rotary table; the oxygen sensing ceramic rotary table has a disc-shaped structure, and several receiving grooves for pressing oxygen sensing ceramics are arranged in a ring array near the edge of the oxygen sensing ceramic rotary table; the oxygen sensing ceramics in the receiving grooves located directly below the output end of the pressing device are pressed by the pressing device, and the location of the pressing device is the oxygen sensing ceramic pressing station. The oxygen-sensing ceramic positioning and locking module has several units and is correspondingly arranged at the edge positions of the upper surface of each receiving slot; the oxygen-sensing ceramic positioning and locking module includes a locking mounting plate, a hinge ear plate, a drive handle, a hook seat, and a locking hook; the locking mounting plate has several units and is in the shape of a rectangular plate, and the locking mounting plate is vertically arranged at the edge of each receiving slot on the upper surface of the oxygen-sensing ceramic rotating platform.

The drive handle has a U-shaped structure, and the outer side of the open end of the drive handle is provided with a pin that is hinged to the hinge hole on the hinge ear plate. The hook seat is a cylindrical structure, and both ends of the hook seat are hinged to the drive handle by pins. The hook seat has a threaded through hole in the direction perpendicular to the axis. The locking hook includes a bent hook section and a screw section; the bent hook section is connected to one end of the screw section, and the other end of the screw section engages with a threaded through hole on the hook seat to install the locking hook on the hook seat. The length of the bent hook section extending out of the hook seat can be adjusted by rotating the locking hook. The locking hook can drive the hook seat to rotate around the drive handle, and the end of the bent hook section hooks onto the oxygen sensing ceramic placed in the receiving groove, thereby pressing the oxygen sensing ceramic into the receiving groove.

[0006] Furthermore, a rubber sleeve is nested on the drive handle.

[0007] Furthermore, the receiving groove at the edge of the oxygen-sensing ceramic rotary table is provided with a profile that fits against the bottom end of the oxygen-sensing ceramic.
