Universal trundle movable support punching device and punching method

Abstract

The invention discloses a universal trundle movable support punching device. The device comprises an upper base plate, wedges, guide plates, a punching sleeve fixing plate, punching sleeves, punches, punch cover plates, sliding seats and a lower base plate, wherein the two wedges are symmetrically installed, the upper ends of the wedges are connected to the upper base plate, the lower ends of the wedges obliquely extend outwards relative to the upper ends to form a splayed shape, the two symmetrically-installed sliding seats are arranged under the lower ends of the wedges, the guide plates, the punches and the punch cover plates are symmetrically installed on the left side and the right side of the punching sleeve fixing plate from near to far respectively, and when the upper base plate is pressed downwards, the wedges push the two sliding seats to be close to the middle, and the two punches are inserted into the two punching sleeves respectively to punch two shaft holes. The invention further discloses a machining method for simultaneously punching the two shaft holes in a movable support at a time by using the universal trundle movable support punching device. According to the universal trundle movable support punching device and the machining method, the two shaft holes in the movable support can be symmetrically punched at a time, and the hole position precision is effectively guaranteed.

Description

technical field [0001] The invention relates to a punching device, in particular to a punching device for a movable bracket of a universal caster, which can be used for punching holes on the bracket of a universal caster. Background technique [0002] Swivel casters are assembled from movable brackets, single wheels, etc. Such as figure 1 As shown, the two side walls 32 of the movable bracket 31 are provided with symmetrical shaft holes 33 for installing a single wheel. The position accuracy of the shaft hole 33 affects the accuracy of the movable caster after assembly. When the position accuracy of the shaft hole 33 is poor, it will cause the related facilities where the movable caster is installed to be unstable, and the shaking will tilt or even overturn when moving, affecting the normal use of the facility. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a punching device for the movable bracket of the univ...
