Description

Support piece and frock for peening Technical Field The application relates to the technical field of surface treatment, in particular to a support piece and a tool for shot blasting. Background Shot peening is a surface strengthening process widely used in factories, i.e., a cold working process in which the work piece surface is bombarded with shot particles and residual compressive stress is implanted to improve the fatigue strength of the work piece. Is widely used for improving the mechanical strength, wear resistance, fatigue resistance, corrosion resistance and the like of parts. Shot blasting generally adopts steel shot, and the steel shot is spherical particle made of special materials through special heat treatment. The steel shot can be divided into steel shot (better toughness, service life several times longer than cast iron shot, wide application), cast iron shot (very brittle, very easy to break, short in service life, and not widely applied. The steel shot is mainly used in places requiring high shot blasting strength), glass shot (mainly used in stainless steel, titanium, aluminum, magnesium, and other situations where iron pollution is not allowed). At present, when a columnar workpiece is subjected to shot blasting operation, the workpiece is required to be supported by using a tool, the tool comprises two supporting pieces which are arranged at intervals, the supporting pieces are arranged into bearing wheel groups, each bearing wheel group comprises two bearing wheels which are arranged oppositely, the bearing wheels are connected through bearings in a rotating mode, a supporting gap is formed between the two bearing wheels, and one bearing wheel group is driven to rotate through a gear motor. In practice, the two sides of the columnar workpiece are placed on the supporting gap, so that the supporting action is realized, the gear motor drives the supporting wheel to rotate, the columnar workpiece is driven to rotate, and the full shot blasting of the surface of the columnar workpiece is realized. The diameter of one end of the columnar workpiece is fixed, but the diameter of the other end of the columnar workpiece can be changed according to actual demands, namely, the columnar workpiece has different sizes, the supporting gap of the existing supporting piece cannot be changed, different supporting pieces need to be replaced to adapt to the workpiece, the axis of the workpiece is horizontal, the rotation can be stable, namely, the applicability of the existing supporting piece is not strong, and improvement exists. Disclosure of Invention In order to adapt to the support of columnar workpieces with different sizes, the application provides a support piece for shot blasting and a tool. The application provides a support piece for shot blasting, which adopts the following technical scheme: the utility model provides a support piece for peening, includes the base, slide on the base and be connected with two back shafts, two the back shaft slides along the direction that is close to each other or keeps away from, two all rotate on the back shaft and be connected with the bearing wheel, two be formed with the support clearance between the bearing wheel, be provided with the driving piece that is used for driving the back shaft to slide on the base. Through adopting above-mentioned technical scheme, utilize driving piece drive back shaft to slide for two back shafts remove along the direction that is close to each other or keep away from, and the back shaft is rotated and is connected on the back shaft, consequently follow the direction that is close to each other or keep away from between two back shafts and remove, realized promptly that the regulation of supporting the clearance changes, the adaptation is not unidimensional columnar work piece carries out the shot blasting operation, helps improving the suitability of this back member promptly. Preferably, the base is located the both sides of arbitrary support wheel and all is provided with the connecting block, two all set up the groove that slides on the connecting block, the back shaft both ends slide respectively in two grooves that slide, the driving piece sets up to the screw rod, screw rod and connecting block threaded connection, just the length direction of screw rod has always with the length direction in groove that slides, the tip and the back shaft butt of screw rod. Through adopting above-mentioned technical scheme, rotate the screw rod, the screw rod is linear motion along the groove that slides, because the tip and the back shaft butt of screw rod realize that the back shaft slides in the groove that slides promptly, and then realize the regulation of the support clearance between two bearing wheels. Preferably, the sliding groove is the opening setting, just the opening in sliding groove all is the direction setting towards the support wheel, the sliding groove is the slope setting, the sliding groove is the slope along t
