The invention relates to an automatic oblique inserting device for a wireless network card, which is used for oblique inserting test on the wireless network card and belongs to the technical field of auxiliary tools. The device of the invention comprises a positioning plate; an insulated cover plate is arranged on the positioning plate; the wireless network card is arranged between the positioning plate and the insulated cover plate; a supporting seat is arranged on the insulated cover plate; a slope is arranged behind the supporting seat; a rotation shaft is arranged on the supporting seat; two ends of the rotation shaft are inserted in a fixing plate; a fixing block is arranged above the supporting seat; the bottom surface of the fixing block is contacted with the slope; the fixing block is connected with the fixing plate via fixing screws; springs are also arranged on the fixing block and the supporting seat; and an adjusting bolt is arranged on the fixing block. A lifting mechanism of the existing stock is used, through a lever principle, conventional straight inserting thinking is broken, automatic oblique inserting and separating of the wireless network card are completed, the test efficiency is high, and the product is not damaged.

The invention discloses a preparation method of an abrasion resistant layer of a stripping die device. The stripping die device includes a mounting seat, a through groove is formed in the mounting seat, a rolling bearing is movably mounted in the through groove, an inner core is fixedly mounted in the rolling bearing, a die head is movably mounted on the inner part, close to one end part of the rolling bearing, of the inner core, a jacking core is connected with the inner part, close to the other end part, of the rolling bearing, of the inner core in a threaded mode and is used for jacking thedie head, and two limiting grooves are symmetrically formed in the two ends of the through groove correspondingly. The stripping die device for aluminum welding wire production is provided, mountingis convenient, performance is stable, the service life is long, stripping quality is good, the direction of a tool edge is convenient to adjust, the situation that pickling equipment is used for removing oil contamination of the surface of the aluminum welding wire in a traditional technology can be replaced, the defects that the environment is polluted by pickling, and skins of operation staff are prone to being corroded can be overcome, the environmental protection effect is achieved, meanwhile the production cost of the aluminum welding wire can be saved, and the preparation method is worthy promoting and popularizing.

The invention discloses a bearing with high-temperature resistance and low speed, comprising a bearing support, at least three roller shafts and a plurality of rollers clearance fitly sleeved on the roller shafts; wherein, the bearing support is fixedly arranged on a non-rotatable part of a rotary machinery; the roller shafts are arranged on the bearing support, and the roller shafts and the rotating shaft are parallel and evenly distributed around a rotating shaft; external circle of the roller is rolling fitted with the rotating shaft. The bearing with high-temperature resistance and low speed has the advantages that the bearing can work under working environment with high temperature and lower rotational speed; any lubricant is not needed; normal and long cycle of production can be maintained and production and maintenance cost are saved.

The invention discloses a method for preventing a knife drum from being abraded. A sunken abrasion-resisting plate installation plane is placed on an inclined plane part corresponding to length direction of an arc-shaped cutting groove, wherein the inclined plane part is placed at the outer end of a fly-cutter support seat. A bolt hole is formed in the fly-cutter support seat corresponding to vertical direction of the abrasion-resisting plate installation plane, and an abrasion-resisting plate fixing bolt is placed in the bolt hole and is in threaded connection with an abrasion-resisting plate. The abrasion-resisting plate is installed on the abrasion-resisting plate installation plane, the surface of the abrasion abrasion-resisting plate is aligned to the inner surface of the arc-shaped cutting groove to jointly form a cutting groove. When timber enters the cutting groove, the timber scrapes and rubs the abrasion-resisting plate and is not directly contacted with the fly-cutter support seat. The method for preventing the knife drum from being abraded has the advantages of protecting the knife drum from not being abraded under a situation of not affecting cutting processes, effectively prolonging service life of the knife drum and saving labor power and material resources. The invention further discloses a knife drum structure capable of preventing abrasion of a drum type chipping machine.

The invention discloses a fixing mechanism of clothes production equipment. The fixing mechanism comprises a main sleeve ring and two elastic retractable mechanisms, wherein each elastic retractable mechanism comprises a first connecting rod and a second connecting rod; one end of each first connecting rod is fixed on the main sleeve ring and the other end of each first connecting rod movably penetrates through one end face of the corresponding second connecting rod; a first supporting plate is arranged on an outer wall of each first connecting rod and a second supporting plate is arranged onthe outer wall of each second connecting rod; a first spring is arranged between each first supporting plate and the corresponding second supporting plate; each second connecting rod is provided witha bearing seat and a baffle plate; the bottoms of supporting columns are hinged to the bearing seats through pin shafts; side faces of the supporting columns are connected with second springs; the second springs are fixed on the baffle plates; the baffle plates are located between the bearing seats and the main sleeve ring. According to the fixing mechanism of the clothes production equipment, a framework of a sewing coil does not swing greatly relative to a fixing column of a coil disc, so that the sewing coil stably rotates around the fixing column; the fixing column, the framework and a sewing thread are effectively protected and the working efficiency is improved.
