The invention provides a shaft spring which, compared with the prior art, is not limited by changing of weight on the spring during emergency break at full commission, provides high riding comfort, reducing non-linear characteristics of shaking, preventing increasing of parts number and structural complexity due to non-linear characteristics and is excellent in endurance. The shaft spring comprises a main shaft, an outer cylinder which is configured in such a manner of, when viewed from the axis center of a main shaft, enclosing the main shaft, and an elastic portion which is formed in such a manner of laminating alternatively with radial inner and outer directions of an intermediate hard cylinder and the axis center of an elastic layer and installing between the main shaft and the outer cylinder. The main shaft is provided with blocks made of elastic materials, and the blocks approach to each other with the main shaft on the axis center direction of the outer cylinder with preset amount. A body fixed outside the outer cylinder abuts against the blocks, and the blocks are detachably installed on the main shaft.

The invention discloses a variable-density square frame beam metallic combination reed, which is characterized in that a plurality of unit reeds in different density specifications are parallelly arranged in a square hollow casing pipe of a reed frame according to the design requirements of warp density; two ends of the casing pipe are screwed to be fixed by a bolt; each unit reed is a short reed which is demountable, and equivalent in height; two ends of the frame beam of each unit reed are flat-top ends; and the adjacent unit reeds are butted by the flat-top end. The variable-density square frame beam metallic combination reed provided by the invention is not only suitable for producing various variable-density textiles, but also suitable for balancing on-loom density textiles and off-loom density textiles; and meanwhile, a structure of the reed is easy to assemble, disassemble and reassemble, and is suitable for low-volume production of the textiles in various varieties. Compared with the traditional reed in fixed density, the variable-density square frame beam metallic combination reed provided by the invention can be well suitable for the requirements of market variations; and the unit-combined variable-density reed is simple in structure, reasonable in assembly, convenient in dismounting, and is also suitable for standardized manufacturing and production of accessories.

The invention relates to an automatic solder robot comprising a soldering bit, an X-axis module, a Y-axis module, a Z-axis module, a carrying board, a wire feeding mechanism and an electric control box as well as a soldering bit motion mechanism and an accurate solder wire positioning mechanism. The soldering bit motion mechanism comprises a moving device which is connected with the soldering bitand comprises a connecting block, an air cylinder, a sliding plate and a linear sliding rail; the connecting block is used for connecting the upper end of the soldering bit with the cylinder body of the air cylinder together and connected with the sliding plate which is glidingly connected with the linear sliding rail; a solder wire nozzle of the accurate solder wire positioning mechanism is connected with the connecting block through a connecting rod, the connecting block is connected with a connecting shaft which is fixedly connected with a deflection block and is in rotating connection with an elevation block, a clamping block is connected with the elevation block and fixed at the upper end of the soldering bit, a horizontal adjusting screw is in rotating connection with the deflectionblock, and the front end of the horizontal adjusting screw is glidingly connected with the elevation block. The invention can accurately solder melted tin solder in a needed position and improve the efficiency, the product quality consistency and stability.
