Description

Technical Field

[0001] This utility model relates to the field of coding tooling technology, specifically to an automatic coding tooling for hot-state casting cylinder heads. Background Technology

[0002] Currently, cylinder head products are equipped with traceability codes for identification, enabling full-process traceability management in subsequent production processes. In existing technologies, subsequent traceability operations for cylinder head traceability codes are typically concentrated in the heat treatment process. However, this traceability model has significant drawbacks: firstly, it requires additional manpower for traceability code operations, leading to a significant increase in labor costs; secondly, if quality problems occur in the casting, machining, or other upstream processes before heat treatment, the traceability nodes are lagging, making it difficult to quickly locate the source of the problem and efficiently retrieve production data from these upstream processes, such as processing parameters and inspection records. This low traceability efficiency directly results in the inability to fundamentally resolve similar quality problems in cylinder heads, leading to a high recurrence rate. This affects production stability and reduces the overall product qualification rate. Therefore, it is necessary to develop an automatic coding fixture for hot-working cast cylinder heads.

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0026] Please see Figures 1-3 The diagram shows a structural schematic of an embodiment of an automatic marking fixture for hot-line casting of cylinder heads according to this utility model. Please refer to [link / reference]. Figures 1-3 This paper provides a detailed introduction to an automatic marking fixture for hot-process casting of cylinder heads.

[0027] An automatic marking fixture for hot-state casting cylinder heads includes a picking track 100, which is a long, horizontally arranged strip serving as the basic structure for conveying and carrying cylinder heads. It is recommended to use high-temperature resistant Q235B steel plate, with a typical thickness of 8-12mm. The length can be determined based on the production line cycle time and available space, generally 2-3m. A hot-state marking fixture body 200 is bolted to the lower end of the picking track 100. The hot-state marking fixture body 200 provides a positioning reference and marking execution space for the marking machine. It is recommended to use 45# steel forging, with surface quenching treatment to improve wear resistance. The hardness after quenching should be controlled at HRC40-45. The marking points of the marking machine are positioned corresponding to the area above the hot-state marking fixture body 200 to ensure accurate marking.

[0028] The first limiting block 201 and the second limiting block 202 are respectively vertically fixed to the two sides of the picking track 100 and are arranged opposite each other. They are located on both sides of the width direction of the picking track 100. It is recommended to make them with wear-resistant cast iron to avoid excessive wear caused by long-term contact with the cylinder head. The height is designed to be 100-150mm, and the height of the two blocks is the same. The first limiting block 201 and the second limiting block 202 are only fixed to the two sides of the picking track 100. The fixing method can be welding followed by bolt reinforcement to improve the connection stability. The tops of both blocks protrude from the upper surface of the picking track 100. The protrusion height is not less than the distance from the bottom of the cylinder head to the upper surface of the picking track 100, which is usually 50-80mm. This can form a preliminary blocking limit on the cylinder head, which helps to prevent the cylinder head from shifting in the width direction during the conveying process.

[0029] Mounting base 204 and inductive switch 203: Mounting base 204 is a cylindrical structure, embedded between the first limiting block 201 and the second limiting block 202. Its bottom is fixed to the upper surface of the part-retrieving track 100 by bolts. It is recommended to use 45 steel for machining, with a diameter of 50-80mm and a length that matches the width of the part-retrieving track 100. The top of mounting base 204 is fixed to inductive switch 203 by snap-fit. It is recommended to use a diffuse reflection photoelectric switch for inductive switch 203 to adapt to the high temperature environment of the hot wire. The sensing end of inductive switch 203 is set upwards to quickly detect whether the cylinder head is in place, reduce cylinder head waiting time, and improve coding efficiency.

[0030] The lifting cylinder 300 is vertically fixed inside the lower part of the part-retrieving track 100. It is recommended to use a pneumatic lifting cylinder with a cylinder diameter of 80-100mm and a stroke of 50-80mm to ensure that the cylinder head can be completely lifted off the surface of the part-retrieving track 100. The top of the output end of the lifting cylinder 300 is horizontally fixed to the lifting tray 301 by bolts. It is recommended that the lifting tray 301 be made of 304 stainless steel plate to avoid rusting in high temperature environments. The steel plate thickness is 10-15mm, and the area is slightly smaller than the contact area of ​​the bottom of the cylinder head. The lifting tray 301 is located directly below the first limit block 201 and the second limit block 202. When lifting, it can drive the cylinder head to smoothly detach from the part-retrieving track 100, avoiding friction between the cylinder head and the track surface during subsequent positioning adjustments, which would affect the positioning accuracy.

[0031] The bracket 402 has an L-shaped structure and is connected to the top of the part-retrieving track 100 on the side away from the feed end. It is recommended to use 50×50×5mm angle iron for welding and fixing to ensure that the bracket 402 has sufficient support. It is recommended to use pneumatic grippers for the clamping mechanism 400, with the clamping force controlled at 500-800N, which can ensure the clamping of the cylinder head while avoiding damage to the cylinder head due to excessive clamping force. The output end of the clamping mechanism 400 is fixedly installed with the end gripper 401 by screws. The end gripper 401 faces the area between the first limit block 201 and the second limit block 202. It is recommended to wrap the clamping surface of the end gripper 401 with polyurethane material to reduce hard contact with the cylinder head surface and avoid scratching the cylinder head. The end gripper 401 is initially in a non-fully clamped state and is only fully clamped after the cylinder head is accurately positioned to prevent cylinder head displacement.

[0032] The sliding mechanism 500 includes a base 502, a slide rail 503, and sliders 504. The base 502 is positioned below the part-retrieving track 100 and is arranged horizontally, serving as the basic support for the sliding mechanism. It is recommended to use gray cast iron HT200 to improve overall stability. The base 502 is designed to be 3-4m long, with a width matching the part-retrieving track 100. The top of the base 502 is horizontally fixed to the slide rail 503 with bolts. There are two slide rails 503, which are parallel to each other and spaced apart, typically with a spacing of 200-300mm. It is recommended to use HGR20 linear guides to ensure smooth sliding. At least two sliders 504 are slidably connected to each slide rail 503. The sliders 504 are evenly distributed along the length of the slide rail 503 and are adapted to the slide rail 503. The bottom of the part-retrieving track 100 is fixed to the top of the sliders 504 with bolts, allowing the part-retrieving track 100 to slide along the slide rail 503 with the sliders 504, thus improving the stability of the cylinder head movement.

[0033] The first cylinder 501 is horizontally fixed on one side of the top of the base 502. It is recommended to use a standard pneumatic cylinder with a cylinder diameter of 60-80mm and a stroke of 200-300mm to meet the moving distance requirements of the part-picking track 100. The output end of the first cylinder 501 is fixedly connected to the bottom side of the part-picking track 100 through a flange. When the first cylinder 501 is started, it can drive the part-picking track 100 to drive the slider 504 to slide back and forth along the slide rail 503, realizing the automatic switching of the cylinder cover between the coding position and the initial position, reducing manual pushing operation.

[0034] The side-top mechanism 600 includes a second cylinder 601, which is fixed to the top of the base 502 by a bracket and located on one side of the width direction of the picking track 100. It is recommended to use a pneumatic cylinder with a cylinder diameter of 50-60mm and a stroke of 80-100mm. The output end of the second cylinder 601 faces the inside of the picking track 100 and can push the cylinder cover closer to the second limit block 202 to achieve precise positioning of the cylinder cover in the width direction of the picking track 100, further improving the consistency of the marking position.

[0035] The technical solution of this utility model will be further described in detail below with reference to the specific operation process:

[0036] Initial placement and limiting of cylinder head: The hot cylinder head is placed at the end of the picking track 100 by the hoisting equipment or the production line conveyor. The first limiting block 201 and the second limiting block 202 on both sides of the picking track 100 form an initial block against the cylinder head to prevent the cylinder head from shifting along the width direction of the picking track 100. At this time, the bottom of the cylinder head is in contact with the upper surface of the picking track 100.

[0037] Cylinder head detection and lifting: When the induction switch 203 on the top of the mounting base 204 detects the cylinder head, it sends a signal to the control system, which then activates the lifting cylinder 300. The output end of the lifting cylinder 300 extends upward, driving the top lifting tray 301 to lift upward until the bottom of the cylinder head is disengaged from the surface of the part removal track 100. The lifting height should be such that the distance between the bottom of the cylinder head and the track surface is 5-10mm to avoid frictional resistance during subsequent positioning adjustments.

[0038] Cylinder head precise positioning and clamping: After the lifting is completed, the control system activates the second cylinder 601 of the side lifting mechanism 600. The output end of the second cylinder 601 pushes out towards the inside of the part-removing track 100, pushing the cylinder head towards the second limiting block 202 until the side wall of the cylinder head is in close contact with the second limiting block 202, thus achieving precise positioning of the cylinder head in the width direction of the part-removing track 100. After positioning is completed, the control system activates the clamping mechanism 400. The clamping mechanism 400 drives the end gripper 401 to move towards the area between the first limiting block 201 and the second limiting block 202 until the end gripper 401 clamps the side wall of the cylinder head, fixing the precisely positioned cylinder head and preventing displacement during subsequent movement.

[0039] Cylinder head movement and marking: After the cylinder head is clamped and fixed, the control system starts the first cylinder 501. The output end of the first cylinder 501 pushes the part-removing track 100. The part-removing track 100 drives the bottom slider 504 to slide along the top slide rail 503 of the base 502, thereby driving the overall structure and the clamped cylinder head to move towards the hot marking fixture body 200. When the cylinder head moves to the position directly above the hot marking fixture body 200, i.e. the preset marking position of the marking machine, the first cylinder 501 stops moving. The marking machine completes the marking operation at the designated position of the cylinder head based on the positioning reference of the hot marking fixture body 200.

[0040] Tooling reset and cylinder head removal: After the coding machine completes coding, it sends a signal to the control system. The control system controls the first cylinder 501 to reverse, and the output end of the first cylinder 501 pulls the part-removing track 100 and the overall structure along the slide rail 503 back to the initial position. Then, the clamping mechanism 400 controls the end gripper 401 to release the cylinder head, and the output end of the second cylinder 601 retracts to the initial state. Finally, the output end of the lifting cylinder 300 retracts downward, driving the lifting tray 301 to reset downward. The cylinder head is then placed back on the part-removing track 100, and the operator or subsequent conveying mechanism can remove the coded cylinder head and proceed to the next production process.

[0041] Although the present invention has been described above with reference to embodiments, various modifications can be made and components can be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the features in the embodiments disclosed in this invention can be combined with each other in any way.
