Description

Technical Field

[0001] The invention belongs to the technical field of oxygen sensor processing and manufacturing, and particularly relates to a float gasket assembly device for an oxygen sensor. Background Art

[0002] As large-displacement motorcycles become increasingly common, they place increasing pressure on the environment. Consequently, governments are tightening regulations on exhaust emissions. Oxygen sensors emerged in response to this demand. Typically installed in the exhaust pipe, these sensors detect the oxygen concentration in the exhaust and send feedback signals to the ECU, which then controls the fuel injection rate, thereby maintaining the air-fuel ratio of the mixture close to the theoretical value.

[0003] The oxygen sensor generally includes components such as the outer cover assembly, the element, the buoy gasket, the talc ring, the insulator and the gasket. The processing and production of the oxygen sensor includes the step of installing the buoy gasket in the outer cover assembly. In the original processing technology, workers pick up the buoy gasket and manually distinguish the front and back sides of the buoy gasket, and then manually install the buoy gasket in the outer cover assembly. Manual installation has the following disadvantages: 1. Manual installation of the buoy gasket wastes manpower, and there is a risk of incorrectly distinguishing the front and back sides of the buoy gasket during manual installation, resulting in failure; 2. Manual installation, because the position of the buoy gasket on the outer cover assembly is a barrel-shaped structure, manual installation cannot ensure the coaxiality of the buoy gasket with the outer cover assembly after installation, resulting in the skewness of the buoy gasket; 3. It affects the production structure and leads to low production efficiency.

[0004] Therefore, how to provide a buoy gasket assembly device for an oxygen sensor that can save manpower, better ensure the installation accuracy of the buoy gasket, and have a higher degree of automation to better adapt to the production rhythm has become a technical problem to be solved by technical personnel in this field. Summary of the Invention

[0005] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is: how to provide a buoy gasket assembly device for an oxygen sensor that can save manpower, better ensure the installation accuracy of the buoy gasket, and has a higher degree of automation to better adapt to the production rhythm.

[0006] In order to solve the above technical problems, the present invention adopts the following technical solutions:

[0007] The buoy gasket assembly device of the oxygen sensor includes a frame, and a shock material tray is provided at the rear end of the frame; it is characterized in that a support block is horizontally provided at the front end of the frame, and a U-shaped support opening is vertically penetrated through the inner end of the support block, and support grooves are provided on both sides of the support opening to form a support station, and the support station is connected with the discharge end of the shock material tray so that the buoy gasket can be transported to the support station one by one, and the two sides of the buoy gasket can each slide in the support groove; a holding block is provided below the support block and is used to place the outer cover assembly; a vertical assembly rod is provided above the support block, and a vertical movement control structure is provided between the assembly rod and the frame, and a translation control structure is provided between the support block and the frame, the vertical movement control structure can drive the lower end of the assembly rod to vertically insert into the buoy gasket and then insert into the outer cover assembly, and the translation control structure can drive the support block to move outward and make the buoy gasket separate from the support station to fall along the vertical guide of the assembly rod and be assembled into the outer cover assembly.

[0008] In this way, when the above-mentioned device is working, the buoy gaskets in the vibration disk are sorted and output from its discharge end and can enter the support station on the support block one by one. The buoy gaskets sorted by the vibration disk can be set so that the installation surface that is in contact with the inner bottom surface of the outer cover assembly is downward. When the buoy gasket is on the support station, the two sides of the buoy gasket are slidably fitted in the support grooves on the two side walls of the support port. After that, the vertical movement control structure drives the assembly rod to move vertically downward, and the lower end of the assembly rod can be vertically extended into the inner hole of the buoy gasket. At the same time, the translation control structure drives the support block to move outward and causes the buoy gasket to translate outward in the support groove and detach from the support station. After detaching from the support station, the buoy gasket can use the assembly rod as a guide and fall into the outer cover assembly accordingly, thereby allowing the buoy gasket to be installed in the outer cover assembly. In the above-mentioned device, mechanical equipment replaces manual operation, eliminating the need for workers in this area and saving labor costs. It also reduces the uncertainty caused by manual operation and better avoids the risk of missing or incorrect installation. The installation of the buoy gasket using the above-mentioned device can also achieve a more uniform production cycle and improve the production efficiency of the entire production line. Finally, in the above-mentioned assembly method, the assembly rod is inserted into the outer cover assembly, and the assembly rod serves as a guide, allowing the buoy gasket to be more accurately assembled. The coaxiality between the buoy gasket and the outer cover assembly is improved, thereby improving the accuracy and reliability of the assembly.

[0009] Furthermore, the lower end of the assembly rod has a rounded corner structure, and the assembly rod is arranged as a stepped shaft with a smaller diameter at the lower end and a larger diameter at the upper end. In this way, the structural design is more reasonable and more convenient to use.

[0010] As an optimization, the support block includes a horizontal lower support block and an upper support block stacked above the lower support block, and the lower surface of the outer end of the upper support block protrudes downward to form a support protrusion, and the lower surface of the support protrusion is supported on the upper surface of the lower support block. The support block also includes a support sheet arranged between the front ends of the upper support block and the lower support block, and the width of the support opening on the support sheet is set to be larger than the width of the upper support openings of the upper support block and the lower support block, so that the support groove is formed between the upper support block, the lower support block and the support sheet.

[0011] In this way, the structure of the entire support block is simpler, the support groove can be more easily obtained on the support block, it is more convenient to process, and it is more convenient to adjust the width of the support groove.

A barrel-shaped limit sleeve is sleeved on the lower end of the mounting rod, and the lower end of the coil spring is supported on the bottom surface of the limit sleeve, and the upper end of the coil spring is sleeved on the lower surface of the mounting block.

[0021] In this way, the assembly rod as a whole has a certain degree of contractility in the vertical direction, which can prevent the assembly rod from abutting against the outer cover assembly and damaging it, thereby having the effect of protecting the outer cover assembly.

[0022] Furthermore, a guide sleeve is provided in the mounting hole, the mounting rod is installed inside the guide sleeve, and a shaft shoulder or a limit nut is provided at the upper end of the mounting rod to prevent the upper end of the mounting rod from falling out of the guide sleeve.

[0045] In this way, when the above-mentioned device is working, the buoy gaskets in the vibration disk are sorted and output from its discharge end and can enter the support station on the support block one by one. The buoy gaskets sorted by the vibration disk can be set so that the installation surface that is in contact with the inner bottom surface of the outer cover assembly is downward.
