DETAILED DESCRIPTION
[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings. The examples given are only used to explain the present invention and are not used to limit the scope of the present invention.
[0035] refer to Figure 1 and Figure 2 The utility model provides an auxiliary material guiding device for a plate, comprising: a guide component 1, a material guiding component 2, an elastic adjustment component 3 and a macro measuring instrument 4; the guide component 1 is slidably arranged on the material guiding component 2, the elastic adjustment component 3 drives and adjusts the guide component 1 to slide, thereby changing the position of the guide component 1 on the material guiding component 2, and the macro measuring instrument 4 is used to measure the sliding distance of the guide component 1.
[0036] refer to Figure 3 , Figures 6 to 8The guide assembly 1 includes an upper guide 10, a lower guide 11 and a movable base 12. The upper guide 10 and the lower guide 11 are both trapezoidal plate-shaped. The upper guide 10 and the lower guide 11 are arranged opposite to each other at intervals. The upper guide 10 and the lower guide 11 are positioned and connected by four columns 13 at the four corners of the upper guide 10 and the lower guide 11; a lower convex block 101 is arranged on the lower surface of the upper guide 10, and an upper convex block 111 is arranged on the upper surface of the lower guide 11. A gap for conveying the workpiece 5 is reserved between the lower convex block 101 and the upper convex block 111. The lower convex block 101 and the upper convex block 111 are arranged opposite to each other and the butt joint surfaces are both planes. The height of any part of the butt joint surface of the upper convex block 111 and the lower convex block 101 is the same, that is, the butt joint surface of the upper convex block 111 and the lower convex block 101 are parallel.
[0037] A bearing 14 is installed on the column 13 between the upper convex pressure block 111 and the lower convex pressure block 101. The bearing 14 is a ball bearing, whose inner ring is fixed to the outer wall of the column 13, and whose outer ring is located on both sides of the workpiece 5 and connected to the side walls of the workpiece 5. When the workpiece 5 is dragged and moved, the outer ring of the bearing 14 rotates, thereby guiding the movement of the workpiece 5.
[0038] Generally, the straight line where the outer ring of the bearing 14 on the same side of the lower guide member 11 is located is parallel to the straight line where the outer ring of the bearing 14 on the other side is located, that is, the gap between the lower convex block 101 and the upper convex block 111 is of the same height and width. The gap is adapted to the thickness of the workpiece 5. On the one hand, the workpiece 5 passing through the gap can be flattened and shaped, and at the same time, the feeding angle of the conveyed workpiece 5 can be ensured to be always accurate, thereby ensuring the quality of the stamping product.
[0039] Screw holes are provided on the side walls of the upper guide 10 and the lower guide 11, and clamping screws 15 are threadedly connected in the screw holes. The screw holes are arranged perpendicular to the column 13, and the inner end surface of the clamping screw 15 is an arc surface, which is matched with the outer wall surface of the column 13. When the clamping screw 15 is tightened, the column 13 can be pressed against the upper guide 10 or the lower guide 11, so that the spacing between the upper guide 10 and the lower guide 11 is determined. By adjusting the gap height between the upper guide 10 and the lower guide 11, workpieces 5 of different thicknesses can be flattened and conveyed.
[0040] As an example, a slot 102 is provided on the lower convex block 101 of the upper guide member 10. Fig. 9 The workpiece 5 is provided with a convex ridge 50, which is stuck in the slot 102. During the conveying process, the workpiece 5 can be moved in the slot 102 by the convex ridge 50, thereby ensuring that the feeding angle of the workpiece 5 is consistent.
[0041] In order to prevent the bearing 14 on the column 13 from sliding down, two bearing stop washers 17 are sleeved on the column 13. The two bearing stop washers 17 are respectively located outside the upper and lower end surfaces of the bearing 14 and are spaced apart from the bearing 14. The bearing stop washers 17 are circular rings, sleeved and fixed on the outer wall of the column 13, and the outer edge diameter is equal to the inner ring diameter of the bearing 14. When the bearing 14 is stable, the bearing stop washers 17 will not affect the rotation of the outer ring of the bearing 14. When the bearing 14 falls off and slides down, the bearing stop washers 17 can support the bearing 14 to prevent the outer ring of the bearing 14 from rubbing against the lower guide member 11.
[0042] Continue to refer Figure 3 The movable base 12 is arranged below the lower guide member 11, and the movable base 12 includes a slider 121 and a connecting groove plate 122, and the connecting groove plate 122 is arranged on the top of the slider 121; a buckle groove is arranged at the lower part of the lower guide member 11, and the connecting groove plate 122 is stuck in the buckle groove and is positioned and connected by a positioning pin 16, so that the movable base 12 is connected to the upper guide member 10 and the lower guide member 11 as a whole. When the movable base 12 moves, it will drive the upper guide member 10, the lower guide member 11 and the workpiece 5 to move together.
[0043] refer to Figure 4 The material guide assembly 2 includes a mounting base 20, a limiting slide rail 21, a first end fixing block 22 and a second end fixing block 23. The two limiting slide rails 21 are relatively arranged on the top surface of the mounting base 20 to form a sliding cavity. The size and shape of the sliding cavity are adapted to the slider 121 of the mobile base 12 to ensure that the mobile base 12 always slides in a straight line without deflection. The limiting slide rail 21 is L-shaped and is connected to the mounting base 20 by a latch and a countersunk screw. The width of the sliding cavity between the two limiting slide rails 21 is the same at any two locations.
[0044] The first end fixing block 22 and the second end fixing block 23 are respectively arranged at both ends of the limiting slide rail 21 and connected to the mounting base 20. The first end fixing block 22 and the second end fixing block 23 have the same shape and are arranged opposite to each other, the elastic adjustment component 3 is arranged on the second end fixing block 23, and the macro measuring instrument 4 is arranged on the first end fixing block 22.
[0045] Preferably, the macrometer 4 is a micrometer, the measuring end face of the micrometer is connected to the side of the slider 121, and when the slider 121 is adjusted to move by the elastic adjustment component 3, the moving distance of the slider 121 can be accurately measured by the macrometer 4. The micrometer in this embodiment only uses the measuring part of the standard micrometer, and removes its other card joint.
[0046] refer to Figure 5The elastic adjustment assembly 3 includes an adjustment screw 30, a spring 31 and an adjustment nut 32. The adjustment screw 30 passes through the side wall of the second end fixing block 23 and is threadedly connected thereto. An end cap is provided at one end of the adjustment screw 30, and the end cap is connected to the side wall of the movable base 12. The adjustment nut 32 is threadedly matched with the adjustment screw 30 and is provided on the outer wall surface of the second end fixing block 23. The spring 31 is sleeved on the adjustment screw 30, and its two ends are respectively connected to the end cap and the second end fixing block 23. When the adjusting nut 32 is turned, the adjusting screw 30 will be relatively displaced with the second end fixing block 23. When the adjusting screw 30 moves outward relative to the second end fixing block 23, the spring 31 is compressed, and the movable base 12 slides toward the second end fixing block 23. At the same time, the end cap is pressed against the movable base 12 by the elastic force of the spring 31. When the adjusting screw 30 moves inward relative to the second end fixing block 23, the compressed spring 31 rebounds, and the end cap pushes the movable base 12 toward the first end fixing block 22, thereby completing the adjustment of the position of the guide assembly 1. The adjusting screw 30 is a smooth rod on one side of the end cap, which is convenient for sleeve installation of the spring 31.
[0047] The device of the utility model is generally installed on a punching machine and at the feeding end of a die.
