Detailed Description

The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.

Referring to fig. 1-6, a positioning block for a clamp stop comprises a movable slider 1 and a positioning block 2, the positioning block 2 is fixed on a station, the movable slider 1 is connected with the fixed block 2, and the position of the movable slider 1 can be adjusted on the fixed block 2 to adapt to workpieces with different sizes.

Referring to fig. 2, a limiting groove 5 is formed on the upper surface of the positioning block 2, the limiting groove 5 is used for limiting the moving range of the movable slider 1 on the positioning block 2, the limiting groove 5 is a strip-shaped groove, the cross section of the limiting groove is trapezoidal, the trapezoidal shape limits the moving range of the movable slider 1 in the axial direction of the limiting groove 5, and the movable slider 1 is prevented from moving in the axial direction perpendicular to the limiting groove 5.

Referring to fig. 3, the lower surface of the movable slider 1 is provided with a limiting protrusion 4, the limiting protrusion 4 is a bar-shaped protrusion, the cross section of the limiting protrusion is in the shape of an inverted trapezoid, and the limiting protrusion 4 and the limiting groove 5 are matched with each other and move axially along the limiting groove 5.

The number of the limiting grooves 5 can be multiple, and two are taken as an example in the embodiment. Two limiting grooves 5 in the embodiment are respectively arranged on two sides of the upper surface of the positioning block 2 to stably limit the movable sliding block 1. A screw hole 7 is formed in one limiting groove 5, and a second strip-shaped hole 8 is formed in the other limiting groove 5.
