Description

Technical Field

[0001] The present invention relates to the technical field of engine connecting rods, and particularly relates to a single-row to double-row mechanism for an automobile engine connecting rod with an anti-connected part function. Background Art

[0002] In the forging processing manufacturing industry of engine connecting rods, with the rapid development of modern manufacturing industry, using molds for forging processing or stamping forming has become the mainstream development trend in today's manufacturing industry, which will greatly improve the production efficiency of the manufacturing industry.

[0003] After the connecting rod is forged and formed, it needs to be quickly transported into the heat preservation furnace for heat treatment preparation. To prevent the connecting rod forging from cooling too fast and not meeting the process requirements, the existing transmission mechanism connected to the heat preservation furnace needs to quickly transport the connecting rod forging into the heat preservation furnace. However, the transmission chain in the heat preservation furnace is relatively wide, and due to process requirements, the feeding speed of the heat preservation furnace is slow. This results in the connecting rod forgings transported by the transmission mechanism being easily stacked together on the transmission chain. In addition, if there are special situations such as the distance between two connecting rods being too close during the connecting rod transmission process, problems such as the connecting rod colliding with the flap mechanism or the transfer mechanism and causing equipment damage will occur. Summary of the Invention

[0004] In view of the above problems, the purpose of the present invention is to provide a single-row to double-row mechanism for an automobile engine connecting rod with an anti-connected part function, which overcomes the above-mentioned deficiencies of the prior art by adding a material separation function and a single-row to double-row function.

[0005] The single-row to double-row mechanism for an automobile engine connecting rod with an anti-connected part function provided by the present invention includes: a base, a material receiving and transferring mechanism, a material pushing mechanism, a flap mechanism, a transition slideway, and a material separation slide plate installed on the base;

[0006] Among them, the transition slideway is used to receive workpieces and transport them to the material receiving and transferring mechanism. The transition slideway includes: a feeding plate arranged obliquely, the feeding plate is installed at the top position on one side of the base, and the discharge port of the feeding plate is docked with the material receiving and transferring mechanism and the material separation slide plate;

[0007] Among them, the material receiving and transferring mechanism is used to receive the workpieces from the transition slideway and transport the workpieces to the material pushing mechanism. The material receiving and transferring mechanism includes: a group of guide shafts horizontally arranged on the base, a material receiving plate slidably connected to the guide shafts through linear bearings, a pulling cylinder installed on the base for pushing the material receiving plate to slide on the guide shafts, the piston rod of the pulling cylinder is connected to the material receiving plate, and the pulling cylinder drives the material receiving plate to move between the discharge port of the feeding plate and the material pushing mechanism;

[0008] Among them, the pushing mechanism is used to push the workpiece into the tipping mechanism. The pushing mechanism includes: a pallet installed on the base, a plurality of pushing cylinders installed on the pallet, and a blanking plate installed on the piston rod of the pushing cylinder. The blanking plate on the pushing cylinder is used to push the workpiece on the material holding plate into the tipping mechanism;

[0009] Among them, the tipping mechanism is used to turn over the workpiece conveyed by the pushing mechanism. The tipping mechanism is located below the material holding and transferring mechanism. The tipping mechanism includes: a tipping shaft installed on the base and arranged parallel to the guide shaft, a tipping plate fixedly connected to the tipping shaft, and a tipping cylinder installed on the base and driving the tipping shaft. The tipping plate is composed of two tipping plates arranged at an acute angle. The piston rod of the tipping cylinder is hinged to the tipping shaft, and the tipping cylinder drives the tipping plate to rotate through the tipping shaft;

[0010] Among them, the material dividing slide plate is used to divide and convey the workpieces with too close spacing. The material dividing slide plate includes: a first slide plate installed on the base and directly below the discharge port of the feeding plate, and a second slide plate installed on the base and docked with the first slide plate. The first slide plate is inclined between the feeding plate and the second slide plate, and the second slide plate is inclined between the discharge port of the first slide plate and the transmission chain in the heat preservation furnace.

[0011] As a preference of the present invention, the top feeding port and the bottom discharge port of the feeding plate are arranged at 45°, and a photoelectric switch for detecting the workpiece is arranged at the feeding port of the feeding plate.

[0012] As a preference of the present invention, the pushing direction of the pushing cylinder is perpendicular to the pulling direction of the pulling cylinder.

[0013] As a preference of the present invention, there are two pushing cylinders in the pushing mechanism, and the two pushing cylinders are installed side by side on the pallet.

[0014] As a preference of the present invention, a blowing support is fixed on the pallet, and a fixed air pipe for regularly cleaning the scale accumulated on the material holding plate is arranged on the blowing support.

[0015] As a preference of the present invention, the first slide plate is arranged at 40° relative to the ground.

[0016] As a preference of the present invention, the base is composed of support plates on both sides and a bottom cushion plate.

[0017] The advantages and positive effects of the present invention are:

[0018] 1. The present invention cooperates with the material conveying mechanism, the material pushing mechanism, the flap mechanism and the transition slideway to complete the single-row transmission to two-row transmission while maintaining a certain distance between the front-end connecting rods, and the transmission direction is also changed by 90 degrees, thereby avoiding the phenomenon of connecting rods piling up in the insulation furnace.

[0019] 2. The present invention solves the problem of too close transmission spacing between front-end connecting rods through a material dividing slide. One of the two workpieces that are too close enters the conveying connection of the insulation furnace through the material holding and transferring mechanism, the material pushing mechanism and the flap mechanism in turn, and the other directly enters the conveying connection of the insulation furnace through the material dividing slide, thereby avoiding equipment damage caused by the failure of the pushing mechanism and the flap mechanism to react due to the too close spacing between the connecting rods.

[0020] 3. In addition to completing the transmission from single row to double row, the present invention can also turn over the connecting rod through the flipping mechanism, thus avoiding the problem of poor heat treatment caused by inconsistent hardness of the upper and lower surfaces of the connecting rod due to long-distance transmission before the connecting rod enters the holding furnace.

[0027] Figures 1-3Shows a schematic diagram of the overall structure according to an embodiment of the present invention.

[0028] Such as Figures 1-3As shown in the figure, the single-row to double-row mechanism for an automotive engine connecting rod with an anti-connection function provided by an embodiment of the present invention includes: a base 1, a first mounting plate 2, a second mounting plate 3, a material loading plate 4, a first pusher cylinder 5, a second pusher cylinder 6, a support plate 7, a first guide shaft 8, a second guide shaft 9, a pulling cylinder 10, a first turning plate 11, a second turning plate 12, a transition chute (feeding plate) 13, an opposed photoelectric switch 14, a turning shaft 15, a blowing bracket 16, a first slide plate 17, a second slide plate 18, a turning cylinder 19, a first pusher plate 20, and a second pusher plate 21; the base 1 is composed of the first mounting plate 2 and the second mounting plate 3 located on both sides and a backing plate located at the bottom. Two parallelly arranged first guide shafts 8 and second guide shafts 9 are installed at the top position between the first mounting plate 2 and the second mounting plate 3. The material loading plate 4 is installed on the first guide shaft 8 and the second guide shaft 9 through linear bearings. The pulling cylinder 10 is fixed on the first mounting plate 2, and the piston rod of the pulling cylinder 10 is connected to the material loading plate 4. The pulling cylinder 10 drives the material loading plate 4 to reciprocate on the first guide shaft 8 and the second guide shaft 9 and stop at the discharge port of the transition chute 13, the first pusher plate 20, and the second pusher plate 21. The support plate 7 is installed between the first mounting plate 2 and the second mounting plate 3. The chute formed by the first guide shaft 8 and the second guide shaft 9 is arranged in parallel with the support plate 7. The first pusher cylinder 5 and the second pusher cylinder 6 are fixed side by side on the support plate 7 to form two pusher stations. The piston rods of the first pusher cylinder 5 and the second pusher cylinder 6 are fixedly installed with the first pusher plate 20 and the second pusher plate 21. The first pusher plate 20 and the second pusher plate 21 are used to push the connecting rods on the material loading plate 4. The blowing bracket 16 equipped with an air pipe is fixed on the support plate 7 and is located on the side of the second pusher cylinder 6. The transition chute 13 is connected to the second mounting plate 3. The transition chute 13 is inclined at 45° to the ground, and the inclined bottom is slightly higher than the height of the material loading plate 4. The inlet of the transition chute 13 is docked with the discharge port of the external transmission mechanism, and the discharge port of the transition chute 13 is docked with the material loading plate 4. The opposed photoelectric switch 14 is fixed at the inlet of the transition chute 13. The opposed photoelectric switch 14 is used to detect the presence or absence of the connecting rods. The turning shaft 15 is rotatably connected to the front lower part between the first mounting plate 2 and the second mounting plate 3 and is arranged in parallel with the first guide shaft 8; the back of the intersection of the first turning plate 11 and the second turning plate 12 arranged at 90° is connected to the turning shaft 15. The extended part of the back of the intersection of the first turning plate 11 and the second turning plate 12 is hinged to the piston rod of the turning cylinder 19. The turning cylinder 19 drives the top of the first turning plate 11 to be docked with the edge of the material loading plate 4 through the turning shaft 15. The first pusher plate 20 or the second pusher plate 21 pushes the connecting rod from the material loading plate 4 onto the first turning plate 11. The first turning plate 11 turns the connecting rod under the drive of the turning shaft 15 and falls onto the second turning plate 12. The connecting rod on the second turning plate 12 automatically falls due to gravity.The first slide plate 17 is arranged at an angle of 45° with the ground. The upper inclined end of the first slide plate 17 is installed on the second mounting plate 3 and is directly below the discharge port of the transition slideway 13. The position of the first slide plate 17 is slightly lower than the material receiving plate 4 and is docked with the transition slideway 13. The lower inclined end of the first slide plate 17 is docked with the second slide plate 18. The second slide plate 18 is inclined and arranged between the first mounting plate 2 and the second mounting plate 3. The second slide plate 18 is arranged at an angle of 30° with the ground. An avoidance opening is provided on the second slide plate 18 for the turning cylinder 19 to be hinged with the first turning plate 11. The inclined top of the second slide plate 18 is slightly lower than the first guide shaft 8.

[0029] Working principle: The connecting rod after high-temperature forging is transported to the transition slideway 13 along the conveying mechanism. When passing through the opposed switch 14, it is judged whether the transmission of this connecting rod is normal transmission to determine two different processing methods. The position between two connecting rods is at a normal spacing for normal operation, and the position between two connecting rods is too close for special operation.

[0030] Among them, under normal circumstances: The pulling cylinder 10 drives the material receiving plate 4 to move below the transition slideway 13. Under the action of gravity, the connecting rod slides onto the material receiving plate 4. The pulling cylinder 10 drives the material receiving plate 4 to move to the first pushing cylinder 5. The first pushing cylinder 5 pushes the first pushing plate 20, and the pushing plate 20 pushes the connecting rod on the material receiving plate 4 to the front end of the first turning plate 11 and slides along the first turning plate 11 to the connection with the second turning plate 12. The pushing cylinder 5 drives the pushing plate 20 to return, and the pulling cylinder 10 drives the material receiving plate 4 to return to its original position. At the same time, the turning cylinder 19 acts, so that the first turning plate 11 and the second turning plate 12 rotate about 90 degrees along the turning shaft 15. The connecting rod is turned over under the action of gravity and then slides along the second turning plate 12 to one side of the heat preservation furnace transport chain. The turning cylinder 19 returns, driving the first turning plate 11 and the second turning plate 12 to reset; when the next connecting rod passes through the opposed switch 14 on the transition slideway 13, the pulling cylinder 10 drives the material receiving plate 4 to move below the transition slideway 13. After the connecting rod slides onto the material receiving plate 4, the pulling cylinder 10 drives the material receiving plate carrying the connecting rod to return to the second pushing cylinder 6. The second pushing cylinder 6 pushes the second pushing plate 21, and the pushing plate 21 pushes the connecting rod on the material receiving plate to the front end of the turning plate 11 and slides along the first turning plate 11 to the connection with the second turning plate 12. The pushing cylinder 6 drives the second pushing plate 20 to return to its original position. At the same time, the turning air cylinder 19 acts, and the first turning plate 11 and the second turning plate 12 rotate 90 degrees along the turning shaft 15. The connecting rod is turned over under the action of gravity and then slides along the second turning plate 12 to the other side of the heat preservation furnace transport chain. The turning cylinder 19 resets, driving the first turning plate 11 and the second turning plate 12 to reset, and so on in a cycle to complete the single-row to double-row transmission and turning of the connecting rod under normal circumstances.

[0031] Under special circumstances: when the material pulling cylinder 10 does not act or stops during the action and returns to its original position, the connecting rod directly slides onto the heat preservation furnace transmission chain through the transition slideway 113, the first slide plate 17, and the second slide plate 18 by relying on gravity, without performing the transmission and turning actions of changing from single row to double row. To prevent special circumstances after the material receiving plate 4 receives the material, after the material pulling cylinder 10 resets, the second material pushing cylinder 6 and the turning cylinder 19 will perform a material pushing action and a turning action once to ensure that there is no connecting rod on the material receiving plate 4 when the material receiving plate 4 is in the material receiving state. The air pipe fixed on the air blowing support 16 will regularly clean the scale accumulated on the material receiving plate 4 to ensure that the connecting rod slides to a certain position on the material receiving plate 4 under the action of gravity.

[0032] The above is only the specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention can easily think of changes or substitutions, which should all be covered within the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the protection scope of the claims.
