Description

Rolling guide rail automated cutting production line

Technical field

The invention belongs to the technical field of mechanical cutting equipment, and specifically relates to an automated cutting production line for rolling guide rails.

Background technique

Rolling guide rails are widely used in modern CNC machine tools and automation equipment. At present, most of the rolling guide rails used in China are imported. For the sake of precision, economy and transportation convenience of guide rail manufacturing, rolling guide rails are generally made about 4 meters long, with various widths, and the commonly used ones are generally between 15 mm and 65 mm. However, different users have different requirements for the specifications, length, etc. of the guide rails, which requires corresponding cutting of the guide rails. Therefore, most rolling guide rail agents need to cut large quantities and multiple varieties of guide rails before distribution.

There are two traditional ways to cut rolling guide rails. One is manual feeding, hydraulic clamping, and cutting with a special cutting machine. Since the material of the rolling guide rails is alloy steel and has been quenched, it has a very high hardness and cannot be cut with traditional cutting methods. The cutting tool can only be cut by grinding with a grinding wheel. The distance between the cutting end face of the rolling guide rail and the installation positioning hole has accuracy requirements. It is difficult to control the accuracy with manual feeding and the efficiency is very low. The second method is to manually insert a tapered pin into the installation positioning hole of the rolling guide rail as a positioning reference for automatic feeding and cutting. The pin also serves as a transmission mechanism, so the position is fixed. Therefore, for rolling guide rails of different specifications, it must be manually inserted. It is very inefficient to use the mounting hole to align the pin, and the pin and the hole are in line contact and cannot be limited laterally (the width specifications are different), so it is easy to shake left and right during transmission. On the fixture, if the reference plane on the same side is positioned and the other side is clamped, the guide rail will be deformed to a certain extent, thus affecting the accuracy of the guide rail.

The initial positioning mechanism 4 is mainly used to limit the bottom and side positions of the rolling guide rail 13 during transportation to ensure that the surface of the rolling guide rail 13 will not cause large rigid friction with the device during transportation and damage the surface. The mechanism 4 includes a bottom limit component and a side limit component. The bottom limit component is composed of several longitudinal bottom limit rollers 41 distributed at equal distances in the transverse direction. The side limit component is composed of alternating front and rear sides of the rolling guide rail. It is composed of several side limiting rollers 42 arranged.

The fixed plate has a sliding rail 48 adapted to it at a position corresponding to the sliding block 47. The sliding block 47 can move longitudinally along the sliding rail 48. When manually loading materials on the automatic feeding device 1, the The positioning plate 43 moves upward along the slide rail 48 under the action of the cylinder one 45 to resist the right side of the rolling guide rail 13 for limiting. When the loading is completed, the limiting block 43 is moved downward to cancel the limiting so as to facilitate the process. The following steps include three-axis control pins and visual identification.

The rolling guide rail is transported from left to right on the automatic feeding device, so generally the positioning hole at the leftmost end of the rolling guide rail is used as the reference hole and is positioned with a pin. Generally, pin positioning uses a centering method. However, since the diameters of the positioning holes of rolling guide rails of various specifications are different, in order to use one pin to position rolling guide rails of all specifications, this design creatively uses tangent points as the The positioning reference is to determine the diameter of the latch (smaller than the positioning hole) based on the size of the smallest rolling guide mounting hole. Since the diameter of the latch is smaller than the positioning hole, the center of the hole cannot be determined, so this design uses a three-axis control mechanism to make the pin and the guide rail The positioning holes are tangent, and the tangent point is used as a reference to locate the position in the length direction of the guide rail, thereby achieving accurate cutting.

Since the side of the rolling guide rail 13 is the same positioning datum, and the right end face is also the same datum, so for rolling guide rails 13 of different specifications, the position of the first hole on the left end is different, so there must be X-axis and Y-axis movement Only in this way can the positioning holes of the rolling guide rails 13 of different specifications be aligned.

The Y-axis transmission mechanism 6 is connected behind the support plate 2 51 . There are longitudinal sliding rails 2 62 at the left and right ends of the base plate 61 .

The rear bearing seat 75 is fixedly connected to the bracket 76.

The servo motor 71 drives the ball screw 72 to rotate, so that the screw nut 77 connected to it makes linear motion in the horizontal direction, so that the base plate 61 fixedly connected to the screw nut 77 can be driven in the X-axis direction, and finally It drives the Y-axis transmission mechanism 6 and the Z-axis transmission mechanism 5 to drive in the horizontal direction. After the pin 56 on the auxiliary Z-axis transmission mechanism 5 is smoothly inserted into the positioning hole, it is tangent to the positioning hole to find the reference point. After the positioning is completed, the rolling guide 13 Under the horizontal transmission of the X-axis transmission mechanism 7, it is smoothly transported to the cutting device for cutting.

Since the diameter of the mounting hole and the distance from the left end face of the rolling guide rails 13 of different specifications are different, in order to realize the automatic latch, on the basis of using a three-axis transmission mechanism, the present invention also adopts a visual recognition mechanism, mainly using an industrial camera. 8 to identify the location.
