The invention relates to a multipoint positioning auxiliary device. The multipoint positioning auxiliary device comprises a cylindrical base and a cylindrical indexing and positioning mechanism on the base. The indexing and positioning mechanism comprises an indexing disc and an aligning disc which can rotate relatively, the aligning disc is provided with a hemispherical positioning base, the positioning base is provided with a cross positioning groove penetrating through the hemisphere, a positioning wing groove is formed in the position, corresponding to the notch of the cross positioning groove, of the aligning disc, a spherical positioning groove is formed in the centre of sphere of the positioning base, a universal ball connected with a cylindrical scale pole is embedded in the spherical positioning groove, a positioning rod and a positioning wing are arranged between the universal ball and a scale pole body in sequence, the positioning rod is matched with the cross positioning groove, the section of the positioning rod is square, the positioning wing is matched with the positioning wing groove, and a positioning vernier which can slide along the scale pole body is arranged on the scale pole. The multipoint positioning auxiliary device has the advantages of being simple in structure, accurate in positioning, convenient to operate, store and carry and the like, multipoint positioning can be achieved conveniently and rapidly, operation is simplified, and working efficiency is improved.

A bearing for a vehicle, enabling a load sensor to be compactly installed on the vehicle and capable of detecting a load on a wheel with good sensitivity. A ring member (22) is attached to a circumferential surface or an end surface of a stationary member out of an outer member (1) and an inner member (2). The ring member (22) has at an intermediate section of it a first contactless ring section (22b (22f, 22i)) not in contact with the stationary member, has at one end a first contact ring section (22a (22g)) in contact with the stationary member, and has at the other end the following (A) or (B): (A) a second contactless ring section (22c(22d)) having greater wall thickness than the first contactless ring section (22b); (B) a second contact ring section (22e, (22h)) in contact with the stationary member. In (A), a sensor (23) for measuring strain of the ring member (22) is installed on the first contactless ring section (22b), and in (B), the sensor (23) is installed on the first contactless ring section (22f) or first contact ring section (22g) having the smallest wall thickness.

The invention discloses a terminal bending device, comprising: a frame; and a bending tool pivotally installed on the frame. A row of accommodating grooves is formed on the bottom surface of the bending tool, and the terminals to be bent are adapted to be accommodated and positioned in the corresponding accommodating grooves; when the bending tool is rotated, they are accommodated in the corresponding accommodating grooves The terminal is bent under the push of the bending tool. In the present invention, the bending of the terminal can be realized only by turning the bending tool, thereby improving the bending efficiency of the terminal. In addition, a row of terminals can be bent simultaneously by using the bending tool, thereby further improving the bending efficiency of the terminals. The mechanism of this bending device uses the frame as the body, which is respectively fixed on the frame or moves or rotates along the guide rail or rotating shaft fixed on the frame, and can reach any given position within the working range under the action of the driving mechanism. The working position, so as to realize the bending process of digital positioning.

The invention discloses a novel form-removal-free concrete construction technology. A first net, a second net and a steel reinforcement framework are included, wherein two clamps sleeve two sides of the steel reinforcement framework, the clamps located on the two sides of the steel reinforcement framework respectively are opposite, each clamp comprises a first semi-circular plate, the two first semi-circular plates are located on the two sides of the steel reinforcement framework respectively and are opposite, a first buffer layer is arranged on one side, close to the steel reinforcement framework, of each first semi-circular plate, a first arc plate is arranged on one side, far away from each first semi-circular plate, of each buffer layer and contacted with the steel reinforcement framework, and a rotating rod is arranged on each first semi-circular plate. Tamping and form removal are avoided, the cost is lower, and the first net and the second net are mounted on the steel reinforcement framework conveniently and cannot be moved during pouring of self-compacting and tamping-free concrete, so that the concrete pouring effect is good.
