Description

Technical Field

[0001] The utility model belongs to the technical field of collecting hoppers, and particularly relates to a bolt collecting hopper and a positioning device thereof. Background Art

[0002] In the existing production process, the bolt blank needs to be lubricated by injecting oil, which will cause a lot of lubricating oil on the surface of the bolt. After forming, the bolt oil-throwing and drying line needs to be used to remove the lubricating oil, otherwise it will affect the subsequent processes, not only affecting the heat treatment process, but also the hot-dip process.

[0003] The discharge port at the end of the existing bolt oil-throwing and drying line is about 1 meter above the ground, and the bolts or workpieces sent out from the discharge port will directly fall into the bottom of the collection hopper below the discharge port for collecting bolts, making the bottom of the hopper directly in rigid contact with the workpiece, causing the hopper's anti-corrosion layer to fall off, and also causing the risk of damage to the workpiece surface. In addition, the existing collection hopper has a large position deviation during operation, which is not conducive to the subsequent automatic guided vehicle (AGV) transmission and positioning.

[0034] Figure 1 This is a schematic diagram of the bolt collection hopper structure of the utility model embodiment. Figure 1The bolt collecting hopper includes a quadrilateral bottom plate and four quadrilateral side walls thereon, and the bottom plate and the four side walls together enclose a closed collecting space with only the top open. One of the four side walls is a collecting side wall, and the collecting side wall is inclined toward the outside of the bolt collecting hopper. The collecting side wall and the bottom plate form an obtuse angle α, 90°<α≤135°, preferably 105°≤α≤120°. A layer of buffer pad covering the bottom of the bolt collecting hopper is provided on the bottom plate. A positioning seat is provided under the bottom plate, and the positioning seat includes one or more rectangular plates (two plates in the figure) or a frame, and has four bottom angles. Among them, the quadrilateral bottom plate is preferably a rectangular bottom plate. During operation, the collecting side wall of the bolt collecting hopper is placed below the discharge port. When the discharge port discharges, the workpiece falls from the discharge port to the upper part of the collecting side wall and then slides along the collecting side wall to the buffer pad at the bottom of the bolt collecting hopper. Thereby, damage to the workpiece and the hopper caused by the vertical drop during discharge is reduced or avoided. In order to further improve the effect of reducing or avoiding damage to the workpiece and the hopper, a thin shock-absorbing pad can be arranged on the inner side of the collecting side wall. The buffer pad and the thin shock-absorbing pad can be made of sponge or soft foam.

[0035] During operation, the bolt collecting hopper is placed on a positioning device, and the positioning device includes a base and four positioning blocks thereon. The base can be a rectangular platform or a flat plate, and the axis of symmetry perpendicular to the upper surface of the rectangular platform or the flat plate is referred to as the vertical axis of symmetry. The four positioning blocks are arranged at the four corners of the upper surface of the rectangular platform or the flat plate, and the four positioning blocks are arranged in axisymmetric relation to the vertical axis of symmetry, and are mirror-symmetrical relative to a plane passing through the vertical axis of symmetry and perpendicular to the length direction or width direction of the rectangular platform or the flat plate. Each positioning block is provided with a notch toward the vertical axis of symmetry, and the notch has two smooth surfaces, and the two smooth surfaces gradually incline toward the outside of the rectangular platform or the flat plate from bottom to top, so that the intersection of the two smooth surfaces inclines radially outward along the vertical axis of symmetry as the height or thickness of the positioning block increases. The two smooth surfaces and their intersection form an inclined slideway, and the positioning seat of the lower bolt collecting hopper can be accommodated between the four positioning blocks. Each positioning block is used to correspond to one of the four bottom corners of the positioning seat of the bolt collecting hopper. The four bottom corners of the positioning seat of the bolt collecting hopper are accurately positioned at the working position through the four positioning blocks, thereby facilitating the bolt collecting hopper to accurately find the working position and facilitating the subsequent automatic guided vehicle to accurately position the hopper.

[0036] The bolt collecting hopper provided by the utility model reduces damage to workpieces and hoppers caused by vertical drop; the bolt collecting hopper positioning device provided by the utility model improves the accuracy of subsequent AGV transmission positioning, increases the circulation speed of the entire production line, and improves work efficiency.

[0037] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
