According to the gulp valve, stable reset of the gulp valve in use can be achieved, meanwhile, vibration caused by loads and impact vibration in the reset process is reduced, then damage to the gulp valve caused by external force loads in use is effectively reduced, meanwhile, the gulp valve in the use process is monitored in real time, adjustment is convenient, and the use function is stable.

The invention relates to the technical field of switch machines, and discloses a manufacturing method of a friction plate for a switch machine, which comprises the following steps of: preparing materials required by a middle reinforced substrate according to a set ratio, and mixing the materials; a layer of friction material is firstly loaded into a pressing machine, then a layer of middle reinforcing base plate mixed material is loaded, then a layer of friction material is loaded, and the three layers of materials are integrally pressed to form a pressed blank; then the pressed blank is subjected to pressure sintering; the overall strength of the product can be improved through integral forming, and in the subsequent sintering step, the integrally-formed pressed blank is not prone to dislocation. The material of the middle reinforced substrate and the friction material are pressed together to form the friction plate, the substrate does not need to be prepared firstly and then the friction plate does not need to be prepared, the production process of the product is simplified, the production efficiency is improved, and meanwhile it can be guaranteed that the reject ratio is reduced.

The invention relates to the technical field of automobile skylight glass machining, in particular to an edge grinding machine for automobile skylight glass machining, which comprises a base, a bearing plate is fixedly mounted on the upper surface of the base through a bracket mechanism, and two auxiliary sliding tables are mounted on the lower surface of the bearing plate through a vertical moving mechanism; a transverse moving sliding table is installed on the outer sides of the two auxiliary sliding tables through a transverse moving mechanism, a grinding machine is fixedly installed on the front surface of the transverse moving sliding table through a telescopic mechanism, a rotating disc is installed above the bearing plate through a mold pressing mechanism, and a Z-shaped folding piece is installed on the upper surface of the rotating disc through a positioning mechanism; the arc-shaped glass is positioned through the Z-shaped folding piece, so that the arc-shaped glass can be placed on the lower mold in an attached mode, dislocation is not prone to occurring, the clamping plates are contracted through the clamping telescopic cylinders to clamp the upper mold and the arc-shaped glass, the situation that the arc-shaped glass is driven to move due to large force when the grinding machine moves and grinds is avoided, and therefore the percent of pass is increased.

The application relates to the field of screw driving equipment and discloses a screw automatic mounting device which comprises a rack, a tooling arranged on the rack and a pressing mechanism, a pressing plate is arranged on the pressing mechanism, a pressing block is arranged on the pressing plate, the pressing mechanism drives the pressing block to press down the end of a wire harness through the pressing plate; the screw automatic mounting device further comprises a screw supply mechanism, a three-axis driving mechanism and a driving mechanism, the screw supply mechanism delivers screws to a specified area, the three-axis driving mechanism drives the driving mechanism to move to the specified area, the driving mechanism sucks the screws, the three-axis driving mechanism drives the driving mechanism to move above the wire harness assembly, and the driving mechanism drives the screws into the wire harness assembly. The application has the advantages that the wire harness can be pressed by adopting a mechanical pressing mode, the installation between the wire harness and the substrate is not prone to dislocation deviation, mechanical full-automatic screw driving is adopted, the screw installation is more firm, and the situation of missed driving does not occur, so that the qualified rate of the wire harness assembly is greatly improved.

The utility model discloses a freely spliced strip-shaped parquet floor, which particularly relates to the technical field of floors, and comprises a floor main body, a fixed frame is movably arranged on one side of the floor main body, a plurality of slots are arranged on the floor main body, and four second inserting barrels are movably arranged in the fixed frame. And one ends of the two second inserting barrels extend into the two inserting grooves correspondingly, a connecting assembly is arranged in the fixing frame, and the connecting assembly comprises a connecting frame, two first lead screws and four second lead screws. The fixing frame is placed on one side of the floor body, then the two second inserting barrels are sequentially rotated, when the two second inserting barrels are inserted into the two inserting grooves respectively, the floor body and the fixing frame are locked, and finally the long bolts are rotated and extend into the ground, so that the two floor bodies are fixed to the ground. The structure is simple, the two floor bodies are not prone to dislocation, and the using effect is good.

A new energy vehicle battery structure is characterized in that a serpentine cooling tube is used for temperature control. The serpentine cover is formed by bending a double-layer metal sheet structure. A communicating flow cavity is provided between the double-layer metal sheets to improve the heat dissipation performance of the battery. By arranging a cooling cycle heat collection component, the low temperature environment of the battery can be insulated. At low temperatures, the heat collected inside the cooling cycle heat collection component is transferred to the flow cavity of the serpentine cover to maintain the temperature of the battery after parking, prevent the storage and conversion of electricity from being affected by the excessively low temperature, and improve the battery performance. When dissipating heat, the heat generated by the battery body will be absorbed by the serpentine cooling tube inside the serpentine cover, so that the heat on the surface of the battery body is reduced, and a large amount of heat accumulation is avoided to cause damage to the battery. The heat can also be stored in the phase change heat storage material when the car is running, so that there is no need to waste extra battery energy when the battery is insulated.
