Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of pipe fitting processing, in particular to a vacuum suction cup auxiliary tooling for pipe fittings. Background Art
[0002] During CNC machining operations, the workpiece to be machined needs to be clamped. Currently, this is done by a vacuum square suction cup. An adsorption plate is provided on the top of the vacuum suction cup, and a plurality of air holes are provided on the adsorption plate. The air holes apply negative pressure to the workpiece through the adsorption force of an air pump so that the workpiece does not move. However, when the existing vacuum suction cup is used to clamp tubular workpieces or workpieces of irregular shapes, it is limited by the plane form of the adsorption plate and cannot be fully applied to workpieces of special shapes. Utility Model Content
[0003] The utility model aims to provide a vacuum suction cup auxiliary tooling for a tubular pipe fitting to be processed in view of the deficiencies in the prior art.
[0004] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a vacuum suction cup auxiliary tooling for pipe fittings, including a vacuum suction cup, a processing part, and an auxiliary adsorption tooling, the vacuum suction cup including a groove-shaped shell, an adsorption plate is provided in the groove of the groove-shaped shell, the upper surface of the adsorption plate is flush with the upper surface of the groove edge of the groove-shaped shell, the groove edge of the groove-shaped shell is provided with a plurality of screw holes, the adsorption plate is provided with a plurality of air holes arranged in an array, an auxiliary adsorption tooling is provided above the vacuum suction cup, the auxiliary adsorption tooling includes a bottom plate and a positioning plate, the top of the bottom plate is provided with a processing groove, the positioning plate is located on both sides of the bottom plate, one side of the positioning plate is tightly fitted with the bottom plate, and the positioning plate is provided with through holes corresponding to the screw holes and matching screws. It needs to be further explained that when the workpiece is a pipe, if the bottom of the pipe is placed directly on the adsorption plate, it cannot be adsorbed at all because the pore size is often larger than the thickness of the pipe. Even if the thickness of the pipe is larger than the pore size, the adsorption contact area is often too small, resulting in very small adsorption force and poor clamping effect. Therefore, a bottom plate is set as the adsorption contact surface to strengthen the clamping force, and further positioning and fixing with the workpiece is formed by processing grooves and positioning steps.
[0005] Preferably, the bottom of the processing piece is inserted into and fits into the processing groove.
[0006] Preferably, the processing groove is determined according to the shape of the bottom of the workpiece, including a single or a combination of a plurality of circles, rectangles and U-shaped grooves.
[0007] Preferably, a plurality of positioning steps are provided around the processing groove.
[0008] Preferably, the positioning step fixes the workpiece in an inserted or fitting manner according to the shape of the workpiece. It should be further noted that since there are mounting screw holes for self-assembly at the bottom of some workpieces, the mounting screw holes of the workpiece are directly used as positioning points here, and the shape and position of the positioning step are set according to the existing notches and mounting screw holes of the workpiece, which is convenient and fast.
[0009] Compared with the prior art, the utility model has the following advantages: by setting an auxiliary adsorption tooling, the adsorption area is increased, so that the clamping effect is better; the position transfer and positioning of the workpiece are realized through the bottom plate and the positioning plate, which is convenient to adjust and fix the position of the workpiece; the workpiece is fixed on the auxiliary adsorption tooling through the processing groove and the positioning step, which is convenient for the positioning of the workpiece when it is taken repeatedly, reduces the time for repositioning after each processing, and greatly improves the processing efficiency.
