The utility model relates to the technical field of garment processing, and discloses an automatic cutting device for garment processing, which comprises a bottom plate, a workbench is fixedly connected to the middle of the top end of the bottom plate, a supporting block is fixedly connected to the middle of the bottom end of the workbench, and first fixing plates are fixedly connected to the left side and the right side of the top of the bottom plate. A supporting pad is fixedly connected to the position, close to the edge, of the left side of the top of the bottom plate, a motor is fixedly connected to the top of the supporting pad, a threaded rod is fixedly connected to the output end of the motor, a U-shaped frame is slidably connected to the top of the bottom plate, and a first telescopic rod is fixedly connected to the middle of the bottom end of the U-shaped frame. According to the cloth cutting device, the motor drives the threaded rod to rotate, the first telescopic rod enables the cutting blade to move up and down for cutting, the second telescopic rod enables the U-shaped frame to move front and back, in this way, cloth can be rapidly positioned to the proper position below the cutting blade during cutting, the cloth does not need to be moved manually, and the positioning efficiency and precision are improved.

The utility model relates to a tool sharpener head fixing frame which comprises a mounting plate which is of a rectangular structure, and a grinding mechanism is fixedly mounted at the upper end of the front side face of the mounting plate and used for grinding a cutting edge of a tool. The positioning mechanism is fixedly mounted at the lower end of the front side face of the mounting plate, a positioning hole is formed in the middle of the positioning mechanism, and the lower end of the polishing mechanism penetrates through the positioning hole. The telescopic mechanism is fixedly mounted in the middle of the rear side face of the mounting plate and can drive the grinding mechanism to move front and back to adapt to the cutter edge radian of the cutter. Through the linkage design of the telescopic mechanism and the positioning mechanism, the grinding mechanism can dynamically adjust the front-back movement track along with the radian of a tool edge, so that the grinding head automatically forms an arc-shaped movement path and is accurately attached to a blade curve, and the problem that the radian area is not fully machined due to traditional linear grinding is effectively solved; and the uniformity and sharpness of the blade are obviously improved.

This application belongs to the field of hydro-generator installation and discloses a stator core slot clamping device for hydro-generators with measuring function. It includes a support cylinder and an insert block disposed at the front end of the support cylinder. The first end face of the insert block has outwardly extending lugs on both sides, and the opening formed by the lugs and the first end face mates with the slot opening of the hydro-generator stator core slot. A measuring scale is provided on the outer side of the insert block. A pressure sensor is provided on the inner side of the first end face of the insert block. A threaded through hole is provided in the middle of the insert block, and a screw rod is provided inside the support cylinder. The screw rod passes through the threaded through hole and is threadedly connected to the insert block. This reduces the difficulty of clamping the stator core wires in the hydro-generator and improves installation efficiency. The pressure sensor, in conjunction with the measuring scale, can determine whether the stator wires are clamped firmly and tightly against the bottom surface of the core slot, solving the problem that the stator wires are not easily fully lowered to the bottom of the stator core slot during installation, thus affecting the installation of the slot wedges.

This invention provides a casting process for fixing markings on high-manganese steel frogs. A support block is fitted between the marking sand mold on the side of the model rail wall and the bottom of the model rail wall within the sand box. The marking sand mold has a special cross-sectional structure to prevent displacement. One side of the marking sand mold is tightly attached to the model rail wall; the lower side is supported and fixed by the support block; and the surrounding area is tightly wrapped with molding sand. After hardening and demolding, the support block area is filled and solidified with molding sand to ensure that the marking sand mold and the model rail wall remain coplanar. This reduces the amount of grinding required due to non-coplanarity between the marking sand mold and the model rail wall, and also standardizes the position of the markings on frogs of the same model. This invention solves the technical problems of marking sand mold displacement and excessive grinding of the markings on the castings; the markings on the cast frogs of the same model are standardized and neat, making it suitable for widespread application.

The invention discloses building steel structure intelligent welding complete equipment, and relates to the technical field of welding, the building steel structure intelligent welding complete equipment comprises a sliding rail, a fixing plate fixedly connected to the outer side of a sliding table, a supporting frame arranged on the inner side of the sliding rail, and a hydraulic telescopic rod fixedly connected to the outer side of the fixing plate, the telescopic end of the hydraulic telescopic rod is fixedly connected with a fixing frame; the electric rod at one end below the sliding plate pushes the connecting plate to descend, so that the grinding mechanism at the bottom of the connecting plate pretreats the weld joint of the two plates, surface oxide layers, oil stains and impurities are effectively removed, the risks of defects such as air holes, welding slag and cracks generated in the welding process are remarkably reduced, and therefore the compactness and structural strength of the weld joint are ensured.

This invention discloses an intelligent bed, including a bed frame, a mattress, a pillow, a pillow drive mechanism, and a control system. The pillow has a head support area and a neck support area at its top. A frame is installed inside the pillow, and the frame includes a neck support section. The pillow drive mechanism includes a mounting base, a rotary drive device, and a rotating shaft. An eccentrically positioned swing member is sleeved on the rotating shaft. The top of the swing member is connected to the bottom of the frame. The rotary drive device drives the rotating shaft to rotate back and forth at a certain angle via a transmission component, which in turn drives the neck support section to swing up and down via the swing member. A detachable strap is attached to the pillow. The control system has a cervical spine anti-arch traction mode. In this mode, the first lifting mechanism and the pillow drive mechanism simultaneously reciprocate to achieve anti-arch traction correction of the neck by the neck support section. The detachable strap ensures that the neck is in close contact with the neck support area, improving the massage effect of the cervical spine anti-arch traction.

The application discloses a kind of plasma arc welding equipment with smoking function for medical instrument processing, it is related to medical instrument welding relevant technical field, in traditional technology, for the welding process of medical instrument with smoking function, gas is ejected from welding site, gas will quickly drift away from welding site, thus causing gas waste, and in the welding process, high-temperature welding slag produced will also be blown by gas and splash, easily hurt operator;And the device forms a semi-closed welding area by the protective shell main body in the protection mechanism and the movable protective shell, forces the inert or active gas ejected by welding module to slowly dissipate from both ends, rather than quickly drift away, greatly reduces gas consumption, optimizes gas utilization rate, limits welding slag inside the protective shell, this closed environment avoids the harm of welding slag splashing to operator, especially when high-frequency welding medical instrument, reduces safety risk.
