5results about How to "Improve vertical accuracy" patented technology

The present invention provides a geological survey sampler with an angle adjustment bracket, comprising a sampler body, wherein the sampler body comprises a driving device and a drill bit, and the driving device and the drill bit are transmission-mounted, and the bottom of the driving device is located on both sides of the drill bit mounting position and is rotatably mounted with two sets of lifting handles through a rotating shaft. Compared with the prior art, the vertical accuracy of the drill bit drilling can be effectively improved, and compared with rough manual estimation, the accuracy is higher, and the soil sampling is more accurate. By reducing the impact of the drill bit's shaking on the surrounding environment and the squeezing effect on the ground around the borehole, the phenomenon of ground cracking around the borehole is reduced, and the surrounding environment is protected. It is simpler and more labor-saving to pull out the device later, and the ground will not be damaged. It has strong adaptability to the ground in different environments, can be adjusted and fixed on the ground according to the ground conditions, and the stability of the bottom of the device is enhanced.

The application discloses an adaptive foot pressing device for a robot end effector and the end effector. The end effector comprises a base unit, and the device comprises a receiver, a foot pressing unit, an elastic reset assembly and a non-contact distance measuring assembly. The foot pressing unit is movably connected with the receiver and can adaptively deflect to fit a workpiece when pressed; the distance measuring assembly detects the distance between the base and the workpiece, and feeds back to guide the robot to adjust the posture to realize normal alignment. The end effector is also provided with a switching unit which integrates drilling, hole diameter and hole depth measurement and hole detection hole units, and through movement, the units can successively share a second channel to work. The application solves the problems of difficult normal alignment and rigid collision of complex curved surfaces, realizes the full-process automation and closed-loop control of normal alignment, hole making, dust collection and detection, and significantly improves the machining precision and efficiency.

The utility model relates to the technical field of stamping dies, and discloses a guiding and supporting integrated aluminum foil container stamping die which comprises a lower die assembly and further comprises an installation base fixed to the outer side of the lower die assembly, an installation rod is fixedly connected to the interior of the installation base, a guiding supporting column is fixedly connected to the outer side of the installation rod, and the guiding supporting column is fixed to the lower die assembly. The guide supporting column is matched with the guide sleeve to guide the movement of the lower die assembly, the guide sleeve is arranged to ensure good vertical precision of the lower die assembly, and the guide sleeve is matched with the guide supporting column to achieve the guide effect, so that the die is more compact in structure, more die cavities can be arranged in a smaller size range, and the production efficiency is improved. The utilization rate of raw materials during production of aluminum foil container products is improved, the production cost is reduced, meanwhile, the structure is simplified, the number of parts of the mold is reduced, the reliability of the mold is improved, and the manufacturing cost of the mold is reduced.

The vertical quenching furnace comprises a deep well heating furnace, a quenching liquid pool, a feeding port, a discharging port, a heating wire and a communicating structure, the feeding port is formed in the top of the deep well heating furnace, the discharging port is formed in the bottom of the deep well heating furnace, the top of the quenching liquid pool is connected with the discharging port of the deep well heating furnace, and the heating wire is installed on the inner wall of the deep well heating furnace. The furnace pipe is of a detachable structure, the communicating structure is connected with the deep well heating furnace and the quenching liquid pool, the heights and sizes of the quenching liquid pool and the deep well heating furnace are adjusted according to the size of a workpiece, and through the design of vertical hoisting and closed connection, the contact time of the workpiece and air in the process from discharging to quenching is effectively shortened, the oxidation risk is reduced, and the quenching quality is improved; the device has the advantages of reducing temperature difference and hardness difference, improving workpiece quality, being environment-friendly, safe and the like, and is suitable for quenching requirements of different workpieces in different scenes.

The invention discloses an assembling method of an oil-leakage-proof press-resistant ultrathin fan, which comprises the following steps: preparing a base, a sliding bearing, a rotor assemblage and a supporting assembly, and integrally forming a supporting column on a middle pipe to obtain the supporting assembly; riveting a supporting assembly at the mounting hole to obtain a first semi-finished product; arranging the FPC and the stator outside the first semi-finished product; the first gap and the second gap which are different in size are defined by the grooves of the supporting columns and the inner wall of the shaft core, lubricating grease of the first gap and the second gap generates high pressure, lubricating oil between the outer surface of the shaft core and the sliding bearing is prevented from overflowing from the second gap, and the sliding bearing is prevented from overflowing through the pumping effect or the labyrinth sealing effect generated by the grooves when the rotor rotates. Lubricating oil is actively prevented from overflowing and leaking along the shaft core, so that a dynamic sealing mechanism is more reliable compared with traditional static sealing, the problem that lubricating oil leaks when an ultrathin fan runs for a long time or in a high-temperature environment is solved, and stability and cleanliness of the fan in long-term running are guaranteed.
