The inner wall of the plate is flush ④ Prepare some L-shaped angle steels (8) ⑤ Unequal L-shaped angle steels (8) are arranged on the inner wall, and the long screw rod (11) is screwed into the embedded spiral pipe (9) by the nut ⑥ Equilateral L The profiled angle steel (8) is arranged on the outer wall (7) to seal with caulking mortar (3), and the middle layer of cast-in-place concrete in the middle of the laminated wallboard is poured. The prefabricated bay window of the present invention has no everted edge, occupies a small space, and is easy and convenient to manufacture, store and transport. It is suitable for the factory flow operation of building window frames and laminated wall panels. It is easy to assemble on site, speed up the construction, shorten the construction period, have high construction quality and save costs.

This invention relates to one-way clutch bearings. The outer ring and the inner ring are divided into a rolling element installation section and a needle roller installation section in the axial direction. Raceways are arranged on the inner wall of the outer ring and the outer wall of the inner ring of the rolling element installation section, and several rolling elements are arranged on the outer ring and the inner ring. In the upper raceway, the rolling element cage evenly separates several rolling elements; several groups of needle roller groups are arranged between the inner wall of the outer ring and the outer wall of the inner ring of the needle roller installation section, and the needle roller cage separates several groups of needle rollers. The groups are evenly separated; each needle roller group includes the first needle roller and the second needle roller, the first needle roller and the second needle roller are installed in the holding groove on the needle roller cage, the first needle roller and the second needle roller There is a pressure angle between the center line of the two needle rollers and the contact pressure direction of the inner ring; the first needle roller is located at the radially inner end of the retaining groove, the first needle roller is in contact with the outer wall of the inner ring, and the second needle roller is located radially outward of the retaining groove end, the second needle roller is in contact with the inner wall of the outer ring. The invention has the advantages of simple and compact structure, good processability, high precision and guaranteed product quality.

The invention relates to a numerically-controlled drill mechanism for drilling angled oil holes in large-sized engine crankshafts and belongs to the technical field of mechanical equipment. The numerically-controlled drill mechanism comprises a main frame and a bit mechanism; the bit mechanism comprises an axial movement mechanism; a transverse movement mechanism perpendicular to the axial movement mechanism is slidably connected to the upper portion of the axial movement mechanism. A turntable mechanism is slidably connected to the upper portion of the transverse movement mechanism and comprises a turntable mounting plate with the bottom slidably connected to the transverse movement mechanism. The upper portion of the turntable mounting plate is fixedly connected with the bottom of a rotating shaft sleeve. An inner ring of the rotating shaft sleeve is movably connected with a mounting sleeve through a connection structure. An outer ring of the rotating shaft sleeve sleeves the turntable. The upper portion of the turntable is fixedly connected with the upper portion of the mounting sleeve. A rotating gear is fixed to the outside of the turntable and connected with a first motor. The turntable allows the angle of a bit to be automatically adjusted as required.

The present invention discloses a bag type filter including a filtering basket, a filtering bag, a cylinder and several supporting legs. Said filtering bag is provided on the inner wall of the filtering basket which is fixed in the cylinder, the supporting legs are arranged on the bottom of the cylinder. The filter also includes an upper liquid feeding part, a lower press plate and a top cover. The upper liquid feeding part is provided with a locating fin on the inner wall and a liquid feeding por in the side surface, the upper liquid feeding part is fixed on the mouth of the cylinder via thelocating fin, and a liquid feeding flange is arranged at the liquid feeding port, the tope cover is sealed over the upper liquid feeding part, a lower liquid discharging part is arranged on the bottom of the cylinder and is provided with a liquid discharging port, and a liquid discharging flange is arranged at the liquid discharging port. The product of the invention has a reasonable structure and easily replaceable parts, and can avoid the inner leakage such that the quality of product is guaranteed. The filter is made entirely of plastics, which reduces the yield cost and use cost. It adopts UPVC material which makes the product work normally under the condition of acid-alkali and humidification.

The invention discloses a tea capable of digesting and smoothing intestine. The tea is prepared from the effective ingredients of the following raw materials by mass percent: 5%-30% of India Buead, 5%-30% of semen raphani, 10%-25% of semen cassiae, 10%-25% of dandelion, 10%-25% of hawthorn, and 10%-20% of folium mori, and the total mass percent of the above components is 100%. The invention further discloses a preparation method of the tea capable of digesting and smoothing intestine. The method comprises the following steps: cleaning weighed raw materials, and then mixing; crushing accordingto a general method, shaping, sterilizing and drying. The tea capable of digesting and smoothing intestine has the effects of clearing heat and detoxicating, improving appetite and promoting digestion, smoothing intestine and relieving constipation and promoting metabolism, has obvious effects of treating indigestion and constipation, and cannot produce toxic side effect on a human after drinkingfor a long time.

The invention relates to a special combined fixture for machining the upper end face and the lower end face of a round mold crystallizer copper tube and a use method of the special combined fixture. The fixture comprises an installation bottom plate, a first set of upper and lower clamping plates, a second set of upper and lower clamping plates and a positioning plate. The installation bottom plate is used for arranging the fixture on a machine tool or a worktable. The first set of upper and lower clamping plates are vertically arranged at one end of the installation bottom plate, the second set of upper and lower clamping plates are vertically arranged at the other end of the installation bottom plate, the upper clamping plates correspond to the lower clamping plates from the upper portion, and preset shapes are formed between the upper clamping plates and the lower clamping plates so that the copper tube to be machined can be positioned and fixed. The positioning plate is arranged on the machine tool or the worktable and used for positioning the installation bottom plate. By means of the fixture, the standard of upper end face and lower end face machining of the copper tube difficult to precisely position is ingeniously transferred to the fixture, and precise installation and positioning of the copper tube are guaranteed through the specially designed structure of the fixture. Accordingly, errors caused by a lineation method or a simple backer are avoided, it is guaranteed that machined parts are precise and reliable, product quality is improved, and defective products are reduced.
