Description

Technical Field

[0001] This utility model belongs to the field of automotive parts technology, specifically relating to a lathe processing device for automotive products. Background Technology

[0002] In the field of automotive parts processing, the fuel injection ring is a core precision component of the engine fuel system, and its machining quality is crucial to engine performance. Therefore, it places stringent requirements on the positioning stability, clamping efficiency, and cooling accuracy of the lathe machining equipment. However, existing automotive fuel injection ring lathe machining equipment has significant technical shortcomings: In terms of positioning and clamping, most adopt a single-reference positioning structure, which cannot adapt to the multi-reference characteristics of the fuel injection ring. During machining, workpiece offset or rotation is prone to occur, resulting in insufficient machining accuracy. Moreover, clamping often relies on manual operation, which is inefficient, and rigid clamping can easily damage the workpiece. In terms of cooling and protection, the cooling system is mostly an external open design, making it difficult for the cooling oil to accurately cover the critical cutting area, affecting machining quality and tool life. At the same time, the cooling oil lacks an effective recovery and sealing structure, which is prone to leakage, contamination, or damage to the equipment. In terms of automation and stability, there is a lack of intelligent control modules, requiring repeated manual parameter adjustments, resulting in large operational errors. Furthermore, the machining table slides without dedicated limit guides, which is prone to offset and misalignment with the machining equipment, making it difficult to meet the needs of mass precision production.

[0003] To address the shortcomings of existing equipment, multi-dimensional design optimization is required: designing a clamping mechanism adapted to the multi-reference features of the fuel injection ring to achieve precise positioning and rapid clamping, avoiding workpiece damage; improving the cooling system by adopting targeted fuel injection and diversion design to ensure that the cooling oil is precisely applied to the cutting area; adding a cooling oil recovery sealing component and a machining table limiting structure to prevent leakage and ensure sliding stability; and integrating an intelligent control module to achieve automatic preset and execution of machining parameters, reducing manual intervention. This will solve the problems of low machining accuracy, poor efficiency, and high wear of existing equipment, and meet the precision machining requirements of automotive fuel injection rings. Utility Model Content

[0004] The purpose of this utility model is to provide a machining device for automotive products on a lathe, which aims to solve the problems of existing automotive fuel injection ring machining devices, such as insufficient machining accuracy, low clamping efficiency, and easy damage to the workpiece due to the inability of the positioning and clamping structure to adapt to the multi-reference features of the fuel injection ring, and the difficulty of the cooling system to accurately cover the key cutting area and easy oil leakage.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A lathe machining apparatus for automotive products, comprising: A support base is provided, with a first cylinder fixedly connected to its front end, a processing table slidably connected to its top end, a cooling assembly installed at the front end of the processing table, a concave connecting plate fixedly connected to its top end, a second cylinder embeddedly fixedly connected to its top end, a processing device fixedly connected to the telescopic end of the second cylinder, and the processing device slidably connected within the concave connecting plate. Two clamping rings are slidably connected to the machining table, which consists of a cooling oil interface, a built-in cooling channel, and a targeted oil injection hole. The two clamping rings are interlocked with each other. A connecting mechanism is provided inside the machining table to drive the two clamping rings to engage with the oil injection rings.

[0006] As a preferred embodiment of this utility model, the connecting mechanism includes: A lead screw, which is rotatably connected to the inner walls of both sides of the processing table; Two nuts are fixedly connected to two clamping rings respectively, and the two nuts are threaded to the circumferential surface of the lead screw in the left and right directions respectively; Multiple plastic rings are fixedly connected to two clamping rings respectively; The motor is fixedly connected to one side of the processing table, and the output end of the motor is fixedly connected to one end of the lead screw.

[0007] As a preferred embodiment of this utility model, a flow divider is embedded and fixedly connected to the rear end of the processing table, and the target oil injection hole of the processing table is horizontally aligned with the flow divider.

[0008] As a preferred embodiment of this utility model, the top of the support base is provided with a storage groove, and a sealing ring is movably engaged in the middle of the bottom inner wall of the storage groove.

[0009] In a preferred embodiment of this utility model, an intelligent controller is fixedly connected to the rear end of the concave connecting plate, and two label stickers are fixedly connected to the front end of the processing table.

[0010] In a preferred embodiment of this utility model, two limiting rods are fixedly connected to the adjacent ends of the support base and the concave connecting plate, and the processing table is slidably connected to the circumferential surface of the two limiting rods.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This solution solves the problems of insufficient positioning and clamping accuracy, low clamping efficiency, and easy workpiece damage in existing technologies by using a linkage mechanism of motor, lead screw, double nuts, and clamping ring, combined with the plastic ring inside the clamping ring. The motor drives the lead screw to rotate, and the double nuts, due to the engagement of their left and right threads, drive the clamping ring to move synchronously in opposite directions, achieving multi-reference ring-like positioning of the oil spraying ring and preventing workpiece displacement; the elastic contact of the plastic ring prevents indentation and reduces the scrap rate; at the same time, it replaces manual clamping, significantly shortens clamping time, is suitable for mass production, and improves processing accuracy and efficiency.

[0012] 2. This solution improves upon the shortcomings of existing technologies, such as low cooling precision and easy oil leakage, by utilizing the distribution plate of the machining table, the targeted oil injection holes, the collection groove of the support base, and the sealing ring. The distribution plate ensures that the cooling oil is evenly distributed to the targeted oil injection holes, accurately covering the cutting area of ​​the oil injection ring, reducing thermal deformation and extending tool life; the collection groove recovers leaked oil, and the sealing ring seals the gap between the machining table and the support base, preventing oil from contaminating the internal components of the device, reducing maintenance costs, and ensuring a clean machining environment.

Detailed Implementation

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Example 1 Please see Figures 1-4 The present invention provides the following technical solution: A lathe machining apparatus for automotive products, comprising: Support base 1, a first cylinder 2 is fixedly connected to the front end of support base 1, a processing table 3 is slidably connected to the top end of support base 1, a cooling component 301 is installed at the front end of processing table 3, a concave connecting plate 4 is fixedly connected to the top end of support base 1, a second cylinder 5 is fixedly connected to the top end of concave connecting plate 4, a processing device 6 is fixedly connected to the telescopic end of the second cylinder 5, and the processing device 6 is slidably connected inside the concave connecting plate 4; Two clamping rings 7 are slidably connected to the processing table 3. The processing table 3 consists of a cooling oil interface, an internal cooling channel and a targeted oil injection hole. The two clamping rings 7 are interlocked with each other. The processing table 3 is equipped with a connecting mechanism, which is used to drive the two clamping rings 7 to engage the oil injection ring.

[0017] In a specific embodiment of this utility model, the support base 1 is a basic load-bearing component made of high-strength cast iron or steel, used to fix the first cylinder 2, the concave connecting plate 4, etc. Lathe adapter mounting holes or positioning grooves are provided at the bottom to prevent shaking during machining, providing support for the overall structural stability and machining accuracy.

[0018] The first cylinder 2 is the horizontal drive source of the processing table 3. Through its telescopic movement, it drives the processing table 3 to slide along the top guide rail of the support base 1, so as to accurately push the oil injection ring to the processing position or remove it after processing, thereby improving the automation level and positioning accuracy of loading and unloading.

[0019] The machining table 3 is a workpiece support platform for placing the oil spray ring and positioning it in conjunction with the clamping ring 7. It integrates a cooling assembly 301 and has a reserved sliding track for the clamping ring 7, serving as the core carrier connecting positioning, clamping, and cooling functions.

[0020] The cooling component 301 is a sub-component of the machining table 3. It includes a cooling oil interface for connecting to an external system, an internal channel for guiding the cooling medium, and a targeted oil spray hole for spraying oil onto the cutting position. This can quickly remove cutting heat, prevent thermal deformation of the oil spray ring, and extend tool life.

[0021] The concave connecting plate 4 is the installation and guiding frame for the processing equipment 6. The concave structure forms a vertical slide rail, which guides the processing equipment 6 to move up and down, ensuring that its trajectory is coaxial with the oil injection ring axis and guaranteeing processing accuracy.

[0022] The vertical drive component of the second cylinder 5 machining equipment 6 moves the machining equipment 6 along the slide rail of the concave connecting plate 4 via telescopic movement, realizing tool feed and retraction. The speed and thrust are adjustable to adapt to the machining of oil injection rings made of different materials.

[0023] The processing equipment 6 is a processing execution component. Replaceable cutting tools such as internal turning tools and drills are installed at the bottom. It moves precisely under the drive of the second cylinder 5 to complete precision machining operations such as turning the oil injection ring groove and drilling the oil injection hole.

[0024] The two clamping rings 7 are made of wear-resistant alloy. The inner side is adapted to the outer circle of the oil spray ring. The shape can be interlocked to form a complete ring, realizing a ring-like clamping, preventing the workpiece from rotating circumferentially or shifting radially, and ensuring the accuracy of oil groove coaxiality, oil spray hole position, etc.

[0025] The clamping ring 7 drive mechanism in the processing table 3 of the connecting mechanism includes gears, racks, or pneumatic push rods, etc., which are connected to an external power source. It can drive the two clamping rings 7 to move closer to each other for clamping or move away from each other for loosening, thus affecting the clamping efficiency. It works with the cylinder to achieve automated processing cycle.

[0026] Please refer to the details. Figures 1-4 The connecting mechanism includes: Lead screw 9 is rotatably connected to the inner walls of both sides of the processing table 3; Two nuts 901 are fixedly connected to two clamping rings 7 respectively, and the two nuts 901 are threaded to the circumferential surface of the lead screw 9 in the left and right directions respectively; Multiple plastic rings 701 are fixedly connected to two clamping rings 7 respectively; Motor 8 is fixedly connected to one side of the processing table 3, and the output end of motor 8 is fixedly connected to one end of lead screw 9.

[0027] In this embodiment: when it is necessary to clamp the oil injection ring, the motor 8 starts and rotates forward, driving the lead screw 9 to rotate; since the two nuts 901 form left and right threaded engagements with the lead screw 9 respectively, when the lead screw 9 rotates, the two nuts 901 will move synchronously towards each other along the axial direction of the lead screw 9, thereby driving the two clamping rings 7 to move closer to each other; the plastic ring 701 on the inner side of the clamping ring 7 contacts the outer circle of the oil injection ring and gradually fits together until the oil injection ring is firmly clamped.

[0028] When the fuel injection ring needs to be released, the motor 8 reverses, driving the lead screw 9 to rotate in the opposite direction. The two nuts 901 drive the clamping ring 7 to move synchronously in the opposite direction, separating the plastic ring 701 from the fuel injection ring, thus completing the release action. The entire process is precisely controlled by the forward and reverse rotation of the motor 8 to open and close the clamping ring 7, achieving rapid and stable positioning and clamping of the fuel injection ring.

[0029] Please refer to the details. Figures 1-3 The rear end of the processing table 3 is embedded and fixedly connected to a flow divider 303, and the target oil injection hole of the processing table 3 is horizontally aligned with the flow divider 303.

[0030] In this embodiment, the flow divider 303 is embedded and fixed at the rear end of the machining table 3. One end is connected to the built-in cooling channel of the machining table 3, and the other end receives the cooling oil delivered by the external cooling system. Since the flow divider 303 is horizontally aligned with the target oil injection hole of the machining table 3, the cooling oil can be uniformly distributed by the flow divider 303 and synchronously delivered to each target oil injection hole, ensuring that the cooling oil pressure and flow rate of each oil injection hole are consistent, and achieving uniform cooling of the cutting area of ​​the oil injection ring.

[0031] Please refer to the details. Figure 2 The top of the support base 1 is provided with a storage groove 101, and a sealing ring 102 is movably engaged in the middle of the bottom inner wall of the storage groove 101.

[0032] In this embodiment: the receiving groove 101 at the top of the support base 1 surrounds the sliding area of ​​the processing table 3 and is used to receive the cooling oil leaking from the target oil injection hole on the processing table 3, so as to prevent the oil from flowing to the outside of the support base 1; the sealing ring 102, which is movably snapped into the middle of the bottom inner wall of the receiving groove 101, fits against the bottom edge of the processing table 3, and can seal the gap between the processing table 3 and the receiving groove 101, preventing the cooling oil in the receiving groove 101 from seeping into the inside of the support base 1 and damaging the components.

[0033] Please refer to the details. Figures 1-4 The rear end of the concave connecting plate 4 is fixedly connected to an intelligent controller 401, and the front end of the processing table 3 is fixedly connected to two label stickers 302.

[0034] In this embodiment: The intelligent controller 401 at the rear end of the concave connecting plate 4 is connected to the motor 8, the first cylinder 2, and the second cylinder 5 via lines. It can preset parameters such as the clamping force of the clamping ring 7 and the moving distance of the processing table 3, and automatically control the motor 8 to drive the clamping ring 7 to open and close, the first cylinder 2 to drive the processing table 3 to slide, and the second cylinder 5 to drive the processing equipment 6 to feed. The two labels 302 at the front end of the processing table 3 are respectively marked with the specification range of the compatible oil injection ring and the recommended pressure of the cooling oil, so that the operator can quickly check the equipment compatibility parameters and avoid misoperation.

[0035] Please refer to the details. Figures 1-3 Two limiting rods 10 are fixedly connected to the near ends of the support base 1 and the concave connecting plate 4, and the processing table 3 is slidably connected to the circumferential surface of the two limiting rods 10.

[0036] In this embodiment: two limiting rods 10 are fixed at the near ends of the support base 1 and the concave connecting plate 4, and are parallel to the sliding direction of the processing table 3; the processing table 3 has a sliding hole through which it is adapted to the limiting rods 10, and is slidably connected to the circumferential surface of the limiting rods 10; when the first cylinder 2 drives the processing table 3 to slide along the support base 1, the limiting rods 10 can limit the left and right offset of the processing table 3, ensuring that the processing table 3 always moves along the preset trajectory and maintains precise alignment with the processing equipment 6.

[0037] The working principle and usage process of this utility model are as follows: The operator first confirms the parameters through the label 302 on the processing table 3, and then uses the intelligent controller 401 of the concave connecting plate 4 to preset parameters such as the clamping force of the motor 8 and the stroke of the cylinder. The controller commands the first cylinder 2 to drive the processing table 3 to slide along the limit rod 10 to the loading position. After the oil injection ring is placed, the motor 8 drives the lead screw 9 to rotate, causing the nut 901 with the clamping ring 7 to move towards each other, and the plastic ring 701 to fit against the workpiece to achieve precise clamping.

[0038] Subsequently, the first cylinder 2 slides the machining table 3 to the machining position, while the second cylinder 5 pushes the machining equipment 6 down along the concave connecting plate 4 for cutting. At the same time, cooling oil is distributed through the distributor plate 303 and sprayed from the target oil injection hole to the cutting area. Leaking oil is recovered by the collection tank 101, and the sealing ring 102 prevents seepage. After machining, all components are reset, the motor 8 reverses to loosen the clamp, and the workpiece is removed to enter the next cycle.

[0039] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
