6results about How to "Increase the fixed area" patented technology

The utility model relates to welding equipment technical field, the utility model discloses a kind of welding equipment with high-efficiency welding tool, by setting fixing device and auxiliary mechanism, fixing device is used to fixedly for welding plate, auxiliary mechanism is used to expand fixed area, solve the welding equipment on current market when handling different size plate, lack a kind of high-efficiency welding tool that can realize adaptive fixed, this leads to when carrying out welding operation face many inconvenience, traditional welding equipment usually needs manual adjustment or replacement different fixture to adapt to different size plate, this process not only time-consuming and laborious, also prone to the problem of inaccurate positioning due to human factors, and further influence welding quality, in addition, for some special shape or size plate, the existing fixed mode can not provide sufficient support and stability, increase the risk problem of deviation in welding process.

The utility model relates to the technical field of cable test detection, in particular to a robot cable winding torsion test device which mainly comprises a supporting bottom plate, a connecting frame is arranged on one side of the top end of the supporting bottom plate, one end of the connecting frame is connected with a servo motor, and a torsion end clamping block is connected to one side of the connecting frame. A U-shaped groove is formed in the twisting end clamping block, a clamping plate is arranged on one side of the twisting end clamping block, the limiting sliding frame is arranged in front of the top end of the supporting bottom plate, and a protection plate is arranged at the top end of the limiting sliding frame. According to the robot cable winding torsion test device, when a cable is positioned and clamped, the end portion of the cable is bent and penetrates through the U-shaped groove, then the two horizontally protruding sections of the cable are stably clamped, and therefore the fixing area of the cable during fixing is increased; and the contact friction force between the cable and the twisting end clamping block is relieved, so that the cable fixing stability is improved, and the test efficiency of equipment is ensured.

The application discloses a stamping device for lightening aluminum parts, and relates to the stamping technical field. Specifically comprising: a workbench, a rotating assembly is fixedly connected to the bottom of the workbench, a first motor box is arranged at the bottom of the rotating assembly, a base is fixedly connected to the bottom of the first motor box, a punch press is mounted outside the base, and a filter cartridge is arranged inside the workbench; the stamping device for lightening aluminum parts further comprises: a limiting mechanism which is used for placing and fixing aluminum parts, the limiting mechanism is arranged above the workbench, the limiting mechanism comprises a fixed groove, an angle plate is fixedly connected to the inside of the fixed groove, and a placing assembly is mounted in the angle plate; and an absorption mechanism which is used for air extraction treatment on the limiting mechanism and a punch head, the absorption mechanism is arranged above the filter cartridge. The stamping device for lightening aluminum parts achieves the purpose of improving the use efficiency of equipment.

The utility model discloses a kind of screw fixing device suitable for complex working condition, including bottom plate, the bottom plate top is fixedly connected with support base, support base top is fixedly connected with limiting mechanism, bottom plate top is fixedly connected with movable rotating block, movable rotating block top is fixedly connected with hydraulic telescopic rod, and the hydraulic telescopic rod top is fixedly connected with the side of the limiting mechanism bottom plate fixedly connected with side plate, bottom plate side bottom fixedly connected with two fixed angle blocks by side plate, and side plate side fixedly connected with two fixed angle blocks, side plate side fixedly connected with connecting sleeve, connecting sleeve inside is fixedly connected with locking mechanism, the utility model fixes two parts of screw support base and screw round bar, adapts to different installation demand and different specification screw, so that screw can also be firmly fixed under complex working condition, improve the fixed stability and firmness of screw in support base one end, effectively resist the external force action under complex working condition, reduce the risk of screw loosening.

The invention provides a catheter and an assembling method thereof, a sputum suction tube assembly and an endoscope kit, and relates to the technical field of medical instruments. The catheter comprises a catheter body, a transparent film and a fixing piece, the transparent film covers the opening, and a regular light-transmitting area can be formed through the end face of the opening, so that the light-transmitting area is smoother and more reliable, and the imaging quality is effectively improved. The fixing piece is located on the periphery of the edge part of the transparent film. The catheter body, the transparent film and the fixing piece are relatively fixed and connected in a sealed mode. The fixing position of the transparent film can be arranged on the periphery of the catheter body on the basis that the catheter opening is sealed, so that the light-transmitting part and the fixing part of the transparent film are independently arranged. Even if the glue overflows, shrinks and the like occur in the assembly process, the transparent film can still meet the design requirements even if the light-transmitting part, corresponding to the opening, of the transparent film only changes slightly or does not change, and the image acquisition effect of the endoscope is ensured.

The invention relates to a voltage transformation control device, a motor controller and a vehicle. The voltage transformation control device comprises a transformer; the transformer comprises a first circuit board; a main board; the main board comprises a second circuit board; a first reinforcing connection layer; the first circuit board faces one side of the second circuit board; the first reinforcing connection layer comprises a first reinforcing bonding pad; a second reinforcing connection layer; the second circuit board faces one side of the first circuit board; the second reinforcing connection layer comprises a second reinforcing bonding pad; the first reinforcing bonding pad and the second reinforcing bonding pad are welded and fixed, and the first reinforcing bonding pad and the second reinforcing bonding pad are not electrically connected. Through the technical scheme disclosed by the invention, the use reliability of the transformer is improved, the risk that the transformer falls off from the mainboard is reduced, the area of the transformer does not need to be additionally increased, and the cost of the transformation control device is reduced.
