In a method for producing exhaust-gas-conducting devices, in particular exhaust-gas-cleaning devices, the outer geometry of each substrate (10) is determined and, as a function of this outer geometry, an outer housing (14) with coordinated geometry is manufactured, in which the substrate (10) is accommodated and clamped together with a compensating element (12).

The invention discloses a fixture constrained by full degrees of freedom for an impact fatigue testing machine. Under the reciprocating impact of the impact fatigue testing machine, the general fixture cannot guarantee reliable clamping, and may even cause damage to the fixture itself. The present invention is composed of a distance adjusting mechanism, an X-direction clamping mechanism, a Y-direction clamping mechanism, a Z-direction clamping mechanism and a Z-direction clamping self-locking mechanism; The length of the sample; the X-direction clamping mechanism, the Y-direction clamping mechanism and the Z-direction clamping mechanism are used to clamp the sample and constrain all the degrees of freedom of the sample; the Z-direction clamping self-locking mechanism is used to prevent The Z-direction clamping mechanism is loose. The invention can be used for clamping a rectangular cross-section sample used in an impact fatigue testing machine, can restrain all degrees of freedom of the sample, and is provided with a self-locking device in the impact direction, thereby ensuring the reliability and safety of sample clamping.

A gripping arm for a clamping attachment for a forklift has a load engaging inner arm including portions defining a load face. The inner arm is pivotal about a first axis parallel to the load face and pivots about a second axis normal to the first axis to engage and secure a load.

The invention discloses a clamping device for clamping films, comprising a film pressing strip (1), a buckling element and a film pressing strip fixed structure, wherein the film pressing strip (1) is provided with a groove (11) which is in run-through on two ends; the buckling element can be clamped in the groove (11) of the film pressing strip (1) in a detachable mode to clamp the films; the film pressing strip fixed structure fixes the film pressing strip (1) on a strut bar. The clamping device is characterized in that the upper edge and the lower edge of the opening of the groove (11) of the film pressing strip (1) are oppositely provided with an extending blocking part (12) which is generally parallel to the bottom of the groove. The structure has the advantages that the buckling element can be stably clamped and fixed in the groove of the film pressing strip due to the blockage of the extending blocking parts when the buckling element is clamped in the groove of the film pressing strip, thereby being capable of firmly clamping the film in the groove of the film pressing strip. The clamping device has simple and reasonable design structure.

A pneumatic fixture for the mainshaft of machine-tool is composed of a mainshaft with bearings, a central pull rod in said mainshaft and with front end connected to clamping spring and back end with clamp releasing mechanism, a steel ball sleeve on said pull rod and with radial through holes, pull rod sleeve in said steel ball sleeve and with a ring slot, steel balls in said ring slot and matched with external sleeve via said radial through holes, a piston module with bevel bearing, and a cylinder module.

The invention discloses a moving device for large flower pots. The moving device comprises a moving rod I, a moving rod II, a buffer pad I, a buffer pad II, a moving left template, a moving right template, a check bolt I, a check bolt II, a check nut I and a check nut II, wherein the moving left template and the moving right template are symmetrical; an arc side is arranged in the middle part of the inner side of each of the moving left template and the moving right template; the upper surfaces at the two ends of the inner side of each of the moving left template and the moving right template are provided with bosses; and a through hole is formed in a part, close to the outer side of each of the moving left template and the moving right template; the buffer pad I and the buffer pad II are separately adhered onto the surfaces of the upper arc sides of the moving left template and the moving right template through gluing; the buffer pad I and the buffer pad II cling to an outer wall below the upper edge of a flower pot; the check bolts are separately inserted into circular holes in the bosses, and are locked by the check nuts; the moving rod I and the moving rod II are inserted into the outer side through holes in the moving left template and the moving right template; and two people can move a large flower pot by holding the moving rod I and the moving rod II by hand. The moving device is simple in structure and convenient to operate; the moving is labor-saving; the clamping is safe and reliable; and the moving work efficiency is high.
