This utility model discloses a deburring fixture for steel pipe processing, comprising two grinding machines, each grinding machine having a movable grinding disc, and further comprising: a clamping mechanism, disposed between the two grinding machines, for rotating and transporting multiple steel pipes, and individually clamping the steel pipe at the grinding position during transport to maintain its stability during the grinding process; an adjusting mechanism, connected to the bottom of the two grinding machines and the clamping mechanism respectively, for adjusting the distance between the two grinding machines and the clamping distance of the clamping mechanism; and a guiding mechanism, fixedly connected to one side of the clamping mechanism, for guiding the ground steel pipe and removing debris from the ground surface of the steel pipe through vibration. The deburring fixture for steel pipe processing disclosed in this utility model ensures processing stability while shortening the clamping time required, thus improving work efficiency.

The utility model discloses a kind of clamp mould assemblies for TEF pipe expander, including rack, pipe upper clamp mould, pipe lower clamp mould and forming die, the upper wedge block is provided on the pipe upper clamp mould, the lower wedge block that is matched with upper wedge block is provided on the pipe lower clamp mould, the clamping port is provided on the pipe upper clamp mould and pipe lower clamp mould, the chute is opened in the pipe lower clamp mould, a pair of spacing block is provided between the pipe lower clamp mould, the pipe upper clamp mould and pipe lower clamp mould are all installed with clamping pipe, clamping recess is opened in the clamping pipe, the clamping recess is through the pipe upper clamp mould and pipe lower clamp mould. Compared with prior art, the beneficial effects of the utility model are that the upper and lower clamp moulds of clamp mould for TEF pipe expander are provided with interfitting inclined wedge structure, through the cooperation of inclined wedge structure, the upper and lower clamp moulds realize the quick clamping of pipe fittings, improve the stability of clamping, shorten clamping time, thereby improve the production efficiency of TEF pipe expander.

This utility model discloses an automatic adjusting fixture, comprising: a base plate, a cylinder, a double-sided rack, a single-sided rack, a gear mechanism, and a fixture body. The cylinder is fixedly mounted on the base plate, and its telescopic rod end drives the double-sided rack to move via a connecting piece. The double-sided rack and two vertically arranged symmetrical single-sided racks are driven and engaged by the gear mechanism, which includes a first gear and a second gear. The first gear meshes with the double-sided rack, and the second gear meshes with the single-sided rack. Through gear transmission, linear motion is converted into rotational motion, driving the single-sided rack to slide and causing the fixture body to close or open. Through the synergistic effect of the cylinder drive and the gear and rack transmission, the linear motion of the cylinder is converted into rotational motion through the double-sided rack, and then driven by the meshing of the first and second gears, the symmetrically arranged single-sided racks slide synchronously, thereby causing the fixture body to close or open, shortening the clamping time and improving production efficiency.

The utility model discloses a lathe clamp for single end face multi -hole position processing, including disc, support disc, T type bolt, hook shape pressboard, hand pull positioner, positioning pin, Y -shaped piece, support plate, screw rod, round pressure block. Hook shape pressboard has linkage function when pressing tightly, be provided with a plurality of with hand pull positioner matching's positioning hole on the disc, rotate support disc with hand pull positioner, and can change workpiece hole's processing position after through the cooperation of positioning hole on the disc, reduced workpiece positioning, clamping time and processing hole position's conversion time, and once positioning clamping can carry out workpiece single end face multi -hole position's processing, and processing cost is low, and processing efficiency is high.
