Description

Technical Field

[0001] This utility model relates to the field of automotive connecting rod forging technology, and in particular to a connecting rod alignment mechanism for an engine connecting rod feeding production line. Background Technology

[0002] In the rapid development of modern manufacturing, engine connecting rod forging plays a crucial role, involving the production of key equipment such as engines. However, with continuous technological advancements, the manufacturing industry faces increasingly higher demands for production efficiency and product quality. Against this backdrop, automated production has become an urgent need to reduce costs, improve efficiency, minimize human intervention, and ensure the production of high-quality products.

[0003] A crucial step in connecting rod forging is point-to-point inspection to ensure product quality and performance. However, traditional point-to-point inspection requires transporting the connecting rod to a designated position beforehand. But because the position of the connecting rod cannot be guaranteed to be uniform during the feeding and transport process, deviations occur in the position of each connecting rod, leading to frequent inaccuracies in subsequent automatic point-to-point inspections. Utility Model Content

[0022] See Figure 1-4This embodiment provides a connecting rod correction mechanism for an engine connecting rod feeding production line, comprising: two connecting rod correction mechanisms 1 symmetrically arranged on both sides of a conveyor line. The two connecting rod correction mechanisms 1 are used to correct the connecting rods on the conveyor line from irregular angles to angles parallel to the conveyor line direction. Each of the two connecting rod correction mechanisms 1 includes: a correction bracket 2 mounted on a frame on both sides of the conveyor line; a correction cylinder (not shown) mounted on the correction bracket 2 and perpendicular to the conveyor line direction; a support plate 3 fixed to the piston rod of the correction cylinder; and a connecting rod head correction assembly and a connecting rod tail correction assembly fixed to the support plate 3. The connecting rod head correction assembly and the connecting rod tail correction assembly are respectively used to correct one side of the connecting rod in the horizontal direction. Both the head and tail positions of the connecting rod include: a wear-resistant top block 4, a trapezoidal nut 5, a countersunk bolt 6, an adjusting screw 7, a hand-tightening handle 8, a support guide rod 9, a guide plate 10, and a rectangular adjusting block 11. The support plate 3 is a rectangular copper block with a strip-shaped notch 12 that runs horizontally through it. The side wall of the support plate 3 has bolt connection holes that connect to the strip-shaped notch 12. The rectangular adjusting block 11 is fixed to the support plate 3 by a threaded connection to a top-holding bolt in the bolt connection hole. When it is necessary to adjust the position of the head and tail positions of the connecting rod according to the length of the connecting rod, it is only necessary to adjust the left and right positions of the rectangular adjusting block 11 in the strip-shaped notch 12. The rectangular adjusting block 11 has a threaded hole and a mounting hole along the horizontal direction for the adjusting screw 7 and the support guide rod 9 to pass through. The adjusting screw 7 and the support guide rod 9 pass through the threaded hole and the mounting hole of the rectangular adjusting block 11 respectively and are set parallel to the piston rod of the straightening cylinder. The adjusting screw 7 is threaded in the threaded hole of the rectangular adjusting block 11 and can be adjusted back and forth in the threaded hole, so that the connecting rod straightening mechanism 1 can handle different types of connecting rods. The side wall of the rectangular adjusting block 11 has a set screw hole that communicates with the threaded hole. The adjusting screw 7 is fixed in the threaded hole by the set screw installed in the set screw hole to ensure the stability of the adjusting screw 7 when moving back and forth. When adjusting the screw 7, the position of the adjusting screw 7 can be adjusted by simply removing the set screw. The support guide rod 9 is fixed in the mounting hole of the rectangular adjusting block 11. The trapezoidal nut 5 is threaded onto one end of the adjusting screw 7 and located on the side near the conveyor line. The hand-tightening handle 8 is fixed onto the other end of the adjusting screw 7. The wear-resistant top block 4 is fixed to the trapezoidal nut 5 by two countersunk bolts 6. The guide plate 10 is fixed to the two support guide rods 9 and located on the side near the conveyor line. The guide plate 10 has a guide hole for the adjusting screw 7 to pass through. The adjusting screw 7 is located above the two support guide rods 9. The wear-resistant top block 4 is made of plastic. The large end of the trapezoidal nut 5 has two threaded holes and is fixed to the wear-resistant top block 4 by two countersunk bolts 6. The small end of the trapezoidal nut 5 has one threaded hole and is threaded to the adjusting screw 7.

[0023] Work process:

[0024] Step S1: Set a pre-correction section on the connecting rod conveyor line. Add a pre-correction component at the pre-correction section position to guide the connecting rod on the conveyor line to the center position of the connecting rod conveyor line. The pre-correction component consists of two stops symmetrically installed on the frame on both sides of the connecting rod conveyor line. The two stops guide the passing connecting rod to the center line position of the connecting rod conveyor line.

[0025] Step S2: Set a correction section on the connecting rod conveyor line. The correction section is located behind the pre-correction section. Add two connecting rod correction mechanisms 1 and a sensor at the correction section position. The sensor is used to detect whether the head position of the connecting rod on the conveyor line is at the preset position. The two connecting rod correction mechanisms 1 are used to correct the connecting rod on the conveyor line from an irregular angle to an angle parallel to the direction of the conveyor line.

[0026] Step S21: When the sensor detects that the head position of the connecting rod has been delivered to the set position, the straightening cylinder located on the left side of the conveyor line is activated first. The piston rod of the straightening cylinder pushes the support plate 3. The support plate 3 drives the wear-resistant top block 4 in the connecting rod head straightening assembly located on the left side of the conveyor line to push and straighten the head position of the left side of the connecting rod. At the same time, the support plate 3 drives the wear-resistant top block 4 in the connecting rod tail straightening assembly located on the left side of the conveyor line to push and straighten the tail position of the left side of the connecting rod.

[0027] Step S22: After the piston rod of the straightening cylinder on the left side of the conveyor line is pushed to the set stroke (at this time, the angle of the connecting rod is close to the pre-examination angle), the straightening cylinder on the right side of the conveyor line is started. The piston rod of the straightening cylinder pushes the support plate 3. The support plate 3 drives the wear-resistant top block 4 in the connecting rod head straightening assembly on the right side of the conveyor line to push the head position of the right side of the connecting rod. At the same time, the support plate 3 drives the wear-resistant top block 4 in the connecting rod tail straightening assembly on the right side of the conveyor line to push the tail position of the right side of the connecting rod. At this time, the two sides of the head and tail of the connecting rod contact the wear-resistant top blocks 4 of the two connecting rod correction mechanisms 1 to complete the straightening and positioning of the connecting rod.

[0028] Step S23: After the piston rod of the straightening cylinder located on the right side of the conveyor line is pushed to the set stroke (at this time, the angle of the connecting rod is corrected), the straightening cylinders located on the left and right sides of the conveyor line control the piston rod to return to the initial position.

[0029] Step S3: Repeat steps S21 to S23 to complete the continuous correction and positioning of the connecting rods on the conveyor line.

[0030] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
