Technical Field
[0001] This utility model relates to the field of crankshaft processing equipment technology, and in particular to a crankshaft grinding and rust-proof soaking linkage treatment device. Background Technology
[0002] As a key core component of an engine, the crankshaft's machining precision directly affects the engine's performance and lifespan. Precision grinding of the outer cylindrical surface is a crucial step in crankshaft manufacturing, ensuring a good fit between the crankshaft and bearings. The ground crankshaft surface is highly reactive and easily oxidizes and corrodes when exposed to air, thus requiring immediate rust prevention treatment.
[0003] In current production practices, crankshaft grinding and rust prevention treatment are usually two independent processes. Operators first grind the crankshaft on a dedicated grinding machine, then remove the finished crankshaft from the machine and transport it manually or using transfer equipment to another separate soaking tank for rust prevention soaking.
[0004] This production model, which separates processes, has significant drawbacks. First, the process is cumbersome, involving multiple transfers and secondary clamping of workpieces between different machines. This not only consumes substantial labor and time costs but also significantly reduces overall production efficiency. Second, during the transfer process, the precision-machined crankshaft surface is at risk of being bumped and scratched, potentially leading to a decrease in product yield.
[0005] Furthermore, the grinding process itself generates a large amount of metal dust and debris. These pollutants disperse in the workshop air, severely polluting the working environment and posing a potential threat to the health of operators. Existing treatment methods often involve post-processing cleaning or the use of independent dust removal equipment, which makes it difficult to achieve synchronous and real-time treatment with the pollution source, resulting in unsatisfactory results. This production method has a low level of automation and integration, making it difficult to meet the requirements of modern, high-efficiency, and green production.
[0006] Therefore, this utility model proposes a crankshaft grinding and rust-proof soaking linkage treatment device to overcome the shortcomings of the prior art. Utility Model Content
[0007] In view of the problems of existing crankshaft grinding and rust prevention immersion integrated treatment devices, such as scattered processes, low degree of automation, incompatibility with workpieces of different specifications, and environmental pollution caused by grinding dust, this utility model aims to provide a crankshaft grinding and rust prevention immersion integrated treatment device with improved structure that can effectively solve the above problems.
[0008] This utility model provides a crankshaft grinding and rust-proof soaking linkage treatment device, including a frame and a first three-jaw chuck rotatably connected to the frame and driven by a motor; the device also includes an adjustment component, a second three-jaw chuck, an electric slide rail, a lifting head, a grinder, an adsorption component, and a soaking tank.
[0009] The adjustment assembly includes a guide rod slidably connected to the frame, a hydraulic rod fixed to the frame, and a movable plate fixedly connected to one end of the guide rod. A second three-jaw chuck is rotatably connected to the movable plate and coaxially arranged with the first three-jaw chuck. The output end of the hydraulic rod is connected to the movable plate, thereby driving the movable plate to reciprocate along the axial direction of the guide rod. An electric slide rail is fixed to the frame, a lifting head is mounted on the electric slide rail, and a grinder is fixed to the lifting head, with its output end connected to a grinding head. The adsorption assembly includes an adsorption cover covering the grinding head and the grinding area of the crankshaft to be processed, a storage chamber, an adsorption tube connecting the storage chamber and the adsorption cover, and an air pump for generating negative pressure in the storage chamber. The soaking tank is integrally formed or fixed to the frame.
[0010] Through the above structural combination, the functions of crankshaft clamping and adjustment, rotary grinding, real-time dust collection and rust prevention soaking are organically integrated on the same frame to form a complete automated linkage processing system.
[0011] Preferably, the electric slide rail is fixedly arranged along the axial direction of the first three-jaw chuck. This arrangement facilitates the stable reciprocating motion of the grinding head along the length direction of the crankshaft to be processed, thereby achieving uniform grinding of the outer circle of the crankshaft.
[0012] Preferably, the lifting head drives the grinder to slide along a straight trajectory perpendicular to the length direction of the electric slide rail. Through this vertical movement, the radial feed of the grinder head and the contact depth with the crankshaft surface can be precisely controlled, ensuring processing accuracy.
[0013] Preferably, the air pump is connected to the storage chamber via an air extraction pipe. This structure provides a clear and reliable pipeline connection for achieving a negative pressure environment inside the storage chamber, ensuring the stability of the adsorption function.
[0014] Preferably, the device further includes a collection bin located below the storage bin. Furthermore, the bottom of the storage bin is provided with an openable and closable valve communicating with the collection bin. By opening and closing this valve, waste temporarily stored in the storage bin can be conveniently transferred to the collection bin in a timely or quantitative manner for centralized processing.
[0015] Preferably, the motor is fixed to the frame, and the output end of the motor is directly connected to the first three-jaw chuck. This direct connection reduces intermediate transmission links and improves transmission efficiency and reliability.
[0016] Preferably, there are multiple guide rods arranged in parallel to each other. This parallel structure of multiple guide rods can provide a more stable and reliable guide for the moving plate, effectively preventing it from deflecting or shaking during movement, thereby ensuring the moving accuracy of the second and third jaw chucks.
[0017] This utility model has the following beneficial effects: 1. This utility model integrates the crankshaft grinding mechanism, rust-proof soaking tank, and adaptive clamping mechanism onto the same frame, solving the problems of scattered grinding and rust-proofing processes, multiple transfers and clamping, and low production efficiency in the prior art. It achieves the technical effects of linkage processing, simplified production process, and significantly improved overall processing efficiency.
[0018] 2. This utility model solves the problem of existing equipment being incompatible with crankshafts of different lengths and specifications and having poor versatility by setting an adjustment assembly consisting of a hydraulic rod, a guide rod, and a moving plate, which drives the second three-jaw chuck to move axially. It achieves the technical effect of conveniently and quickly adjusting the clamping distance, adapting to different workpieces, and enhancing the versatility of the device.
[0019] 3. This utility model, by setting up an adsorption component that works synchronously with the grinding process, uses the adsorption cover to create negative pressure in the grinding area, which solves the problem of metal dust and debris generated during grinding polluting the working environment and endangering the health of operators, and achieves the technical effect of real-time and efficient collection of waste, keeping the working environment clean, and realizing green production.

[0022] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0023] Example: Please refer to Figures 1 to 4 This utility model provides a crankshaft grinding and rust prevention soaking linkage treatment device, which aims to solve the problems of the existing technology, such as the separation of crankshaft grinding and rust prevention treatment processes, low degree of automation, incompatibility with workpieces of different specifications, and the environmental pollution caused by grinding dust.
[0024] like Figure 1 and Figure 2 As shown, the crankshaft grinding and rust-proof soaking linkage treatment device includes a frame 1, which serves as the mounting base for the entire device. The frame 1 is integrated with a structure for workpiece clamping and driving, a structure for performing grinding, a structure for adaptive adjustment, a structure for waste adsorption, and a structure for subsequent treatment.
[0025] Specifically, a motor 10 is fixedly mounted on the frame 1, and the output end of the motor 10 is directly connected to the first three-jaw chuck 6. The first three-jaw chuck 6 is rotatably connected to the frame 1. An adjustment component 8 is also provided on the frame 1. (Refer to...) Figure 3 The adjustment assembly 8 includes a guide rod 802 slidably connected to the frame 1, a hydraulic rod 801 fixed to the frame 1, and a movable plate 803 fixedly connected to one end of the guide rod 802. The movable plate 803 is connected to the output end of the hydraulic rod 801. The second three-jaw chuck 7 is rotatably connected to the movable plate 803, and the second three-jaw chuck 7 is coaxially arranged with the first three-jaw chuck 6. The movable plate 803 is driven to reciprocate along the length direction of the guide rod 802 by the hydraulic rod 801, which can adjust the distance between the first three-jaw chuck 6 and the second three-jaw chuck 7. There are multiple guide rods 802, and they are arranged in parallel to ensure the stability of movement.
[0026] An electric slide rail 2 is fixed on the frame 1, and a lifting head 3 is installed on the electric slide rail 2. A grinder 4 is fixed on the lifting head 3, and a grinding head 5 is connected to the output end of the grinder 4. The electric slide rail 2 is fixed along the axial direction of the first three-jaw chuck 6, and the lifting head 3 drives the grinder 4 to slide along a straight track perpendicular to the length direction of the electric slide rail 2. The combined motion of the two achieves the precise positioning of the grinding head 5 in space.
[0027] Reference Figure 4 To achieve a clean and environmentally friendly grinding process, an adsorption assembly 9 is installed on the frame 1. The adsorption assembly 9 includes an air pump 901, an air extraction pipe 902, a storage chamber 903, an adsorption tube 904, and an adsorption cover 905. The air pump 901 is connected to the storage chamber 903 through the air extraction pipe 902. One end of the adsorption tube 904 is connected to the storage chamber 903, and the other end is connected to the adsorption cover 905. The adsorption cover 905 covers the grinding area of the grinding head 5 and the crankshaft to be processed. In addition, the frame 1 is also equipped with an soaking tank 11 and a collection chamber 12 for subsequent processing. The soaking tank 11 is integrally formed or fixed on the frame 1. The collection chamber 12 is located below the storage chamber 903. The bottom of the storage chamber 903 is equipped with an openable and closable valve that communicates with the collection chamber 12.
[0028] To solve the above-mentioned technical problems, the technical solution of this embodiment lies in the specific structural cooperation and connection relationship formed between the adjustment component 8, the electric slide rail 2, the lifting head 3, and the adsorption component 9, the frame 1, and the clamping mechanism.
[0029] Please refer to the following carefully. Figure 3 The adjustment component 8 will be described in detail below: The adjustment assembly 8 is designed to achieve adaptive clamping of crankshafts of different lengths. It includes guide rods 802 and hydraulic rods 801, as well as a movable plate 803 fixedly connected to one end of the guide rods 802. There are multiple guide rods 802, which are arranged parallel to the axis of the first three-jaw chuck 6, providing precise guidance and limiting for the reciprocating motion of the movable plate 803. The cylinder of the hydraulic rod 801 is fixed to the frame 1, and its output end, i.e., the piston rod, is fixedly connected to the movable plate 803. The base of the second three-jaw chuck 7 is rotatably connected to the surface of the movable plate 803. By controlling the extension and retraction of the hydraulic rods 801, the movable plate 803 can be driven to move precisely axially along the guide rods 802 with the second three-jaw chuck 7, thereby changing the distance between it and the first three-jaw chuck 6. This sliding adjustment structure, in which the hydraulic rods 801 provide driving force and the guide rods 802 provide guidance, ensures a smooth and fast clamping adjustment process and provides sufficient and stable clamping force.
[0030] Please refer to the following carefully. Figure 1 and Figure 2 The grinding actuator will be described in detail below: The track of the electric slide rail 2 is horizontally fixed to the upper part of the frame 1 along the axial direction of the first three-jaw chuck 6. The slider of the lifting head 3 is slidably engaged in the track of the electric slide rail 2. The lifting head 3 itself also has a lifting drive mechanism perpendicular to the length direction of the electric slide rail 2. The grinder 4 is firmly installed on the lifting head 3. The lifting head 3 drives the grinder 4 and the grinding head 5 to move axially along the electric slide rail 2 and can control their radial lifting movement. This two-dimensional coordinate motion mechanism enables the grinding head 5 to accurately reach any predetermined processing position on the crankshaft surface, ensuring the grinding coverage and processing accuracy.
[0031] Please refer to the following carefully. Figure 4 The adsorption component 9 will be described in detail below: The adsorption hood 905 has a hollow structure, and its opening end is aligned with and as close as possible to the grinding area where the grinding head 5 contacts the crankshaft during operation. One end of the adsorption tube 904 is connected to the top or side wall of the adsorption hood 905, and the other end is connected to the inlet of the storage chamber 903. The air pump 901 evacuates air from the sealed storage chamber 903 through the air extraction pipe 902, creating a negative pressure environment inside. This negative pressure is conducted to the internal space of the adsorption hood 905 through the adsorption tube 904, thereby generating a strong suction at the opening of the adsorption hood 905. This real-time adsorption structure based on the principle of negative pressure ensures that the metal dust and debris generated during the grinding process are immediately sucked away before they splash and spread, ensuring a clean working environment.
[0032] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, in order to achieve uniform axial grinding of the outer circle of the crankshaft, the track of the electric slide rail 2 is fixed parallel to the axis of the first three-jaw chuck 6 on the frame 1. This arrangement allows the lifting head 3 to drive the grinding head 5 to move smoothly back and forth along the length of the crankshaft, covering the entire area to be processed.
[0033] As another preferred embodiment, in order to achieve radial feed and grinding depth control of the crankshaft, the internal lifting mechanism of the lifting head 3 can drive the grinder 4 to slide along a straight trajectory perpendicular to the length direction of the electric slide rail 2, thereby precisely controlling the contact and separation between the grinding head 5 and the crankshaft surface, as well as the cutting depth during the processing.
[0034] As a specific connection method of the adsorption component 9, in order to effectively establish a negative pressure environment in the storage chamber 903, the air outlet of the air pump 901 is airtightly connected to the upper part or side wall of the storage chamber 903 through the air extraction pipe 902, realizing a direct and reliable connection between the negative pressure source and the negative pressure space.
[0035] As a further optimization of the waste disposal solution, in order to facilitate the centralized collection and treatment of waste, the device also includes a collection bin 12. The collection bin 12 is an independent container located directly below the storage bin 903. A discharge port is opened at the bottom of the storage bin 903. An openable and closable valve connected to the collection bin 12 is installed on the discharge port. The valve can be a butterfly valve, a ball valve, or a slide valve, used to control the timed or quantitative discharge of waste in the storage bin 903.
[0036] As a preferred drive structure, in order to simplify the transmission structure and improve transmission efficiency, the motor 10 body is fixed on the frame 1, and the output shaft of the motor 10 is directly connected to the input end of the first three-jaw chuck 6 through a coupling to achieve efficient power transmission.
[0037] To optimize the stability of the adjustment component 8, and to ensure the high stability and anti-deflection capability of the moving plate 803 during movement, multiple guide rods 802 are provided. These multiple guide rods 802 are slidably connected to the frame 1 in parallel with each other. The moving plate 803 is fixed to one end of the multiple guide rods 802, ensuring the coaxiality of the second three-jaw chuck 7 during axial movement.
[0038] The working principle of this crankshaft grinding and rust-preventive immersion combined treatment device is as follows: During processing, the crankshaft to be processed is first placed between the first three-jaw chuck 6 and the second three-jaw chuck 7. The hydraulic rod 801 in the adjustment assembly 8 is activated. The hydraulic rod 801 pushes the moving plate 803 to move axially along the guide rod 802 until the second three-jaw chuck 7 tightly engages the other end of the crankshaft. This adjustment process allows the device to adapt to crankshafts of different lengths and achieve stable coaxial centering clamping.
[0039] Subsequently, motor 10 starts, driving the first three-jaw chuck 6, crankshaft, and second three-jaw chuck 7 to rotate synchronously. Simultaneously, electric slide rail 2 drives the lifting head 3 to move horizontally. The lifting head 3 then drives the grinder 4 to move downwards, bringing the grinding head 5 into contact with the rotating crankshaft surface for outer diameter grinding. The precise combined movement of the electric slide rail 2 and the lifting head 3 ensures grinding accuracy and coverage. During grinding, the air pump 901 in the adsorption assembly 9 starts, creating negative pressure in the storage chamber 903 through the suction pipe 902. This negative pressure acts on the inside of the adsorption hood 905 through the adsorption pipe 904, efficiently drawing iron filings and dust generated in the grinding area into the storage chamber 903, achieving clean production.
[0040] When the waste material in the storage bin 903 reaches a certain amount, the valve at its bottom is opened, and the waste falls into the collection bin 12 below under gravity for centralized processing. After grinding is completed, the motor 10 and the grinder 4 stop working, and the hydraulic rod 801 drives the moving plate 803 to retract and release the crankshaft, transferring the crankshaft to the soaking tank 11 for rust prevention soaking treatment, thus completing the entire linkage process of grinding and rust prevention soaking. Through the synergistic effect of the above components, this utility model solves the problems of dispersed processes, low efficiency, poor versatility, and environmental pollution in the prior art.
[0041] The above description is merely a specific embodiment 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 protection scope of the claims.
