Description

Technical Field

[0001] The present invention relates to a turning processing device for a connecting rod, and more specifically, to an external hexagonal turning processing device for a connecting rod and its control method. Background Art

[0002] CNC cutting tools are tools used for cutting processing in mechanical manufacturing, also known as cutting tools. Among CNC cutting tools, disposable inserts are the type of product that accounts for the largest proportion among all processing tools and are also the most common type of tool in the manufacturing process. Disposable inserts are further divided into two major categories: turning inserts and milling inserts according to different usage ranges. Currently, the more common turning inserts on the market are inserts in the shapes of regular triangles, rhombuses, convex triangles, regular quadrilaterals, etc.

[0003] Currently, the processing of connecting rods is usually achieved through turning processing. Turning processing can select different shapes and models of inserts according to the influence of the shape, size, material, etc. of the product. For the external hexagonal turning method of connecting rods, it usually forms the processing of six faces of the connecting rod through the coordinated movement of the tool and the workpiece. However, the feeding before processing the connecting rod usually adopts manual operation, and the accuracy of feeding is poor. At the same time, the feed rate during the processing also needs to be adjusted manually, consuming a large amount of human resources. At the same time, each device needs to be equipped with an independent processing personnel, and the processing efficiency is low. Moreover, manual operation is difficult to fully adapt to repetitive work and is prone to errors during the processing, resulting in personal safety accidents. Summary of the Invention

[0004] Aiming at the deficiencies of the existing technology, the purpose of the present invention is to provide an external hexagonal turning processing device for a connecting rod and its control method with high automation, which can efficiently process the external hexagon of the connecting rod and can detect the processing effect of the connecting rod during the processing to ensure the qualified rate of the processed products.

[0005] To achieve the above purpose, the present invention provides the following technical solution: An external hexagonal turning processing device for a connecting rod, including a processing machine tool, and further including a feeding structure arranged at one end of the processing machine tool and a loading and unloading structure arranged at the other end of the processing machine tool. A turning structure is arranged between the feeding structure and the loading and unloading structure. The turning structure includes a connecting rod channel and a turning component arranged on one side of the connecting rod channel. The turning component includes a driving motor, a processing tool holder arranged on the driving motor, and a plurality of tool heads arranged along the circumferential direction of the processing tool holder.

[0006] The present invention is further arranged as follows: A limiting component is further arranged at the top of the connecting rod channel. The limiting component includes a pushing cylinder and a baffle arranged on the pushing cylinder. The pushing cylinder is used to push the baffle to move in the vertical direction. A pressure sensor is further arranged on the baffle, and the pressure sensor is used to detect the contact state between the connecting rod and the baffle.

[0007] The present invention is further configured as follows: the loading and unloading structure includes a material transport rack arranged on one side of the processing machine tool and a loading assembly arranged on the material transport rack, and a loading push rod is also provided at the end of the loading assembly away from the turning structure. The loading assembly includes a top plate arranged on the material transport rack and a loading channel arranged on the processing machine tool, and the position of the loading channel matches the position of the connecting rod channel.

[0008] Preferably, the material transport rack is also provided with a discharging assembly, which includes a transmission belt arranged at the bottom of the material transport rack and a discharging platform arranged at the rear end of the material transport rack, and the movement direction of the transmission belt is opposite to the movement direction of the loading push rod.

[0009] The present invention is further configured as follows: the material pushing structure comprises a positioning frame arranged on the processing machine tool and a material discharging push rod arranged on the positioning frame, and the position of the material discharging push rod matches the position of the connecting rod channel.

[0010] The present invention is further configured as follows: a fixed chuck is also provided at one end of the connecting rod channel close to the turning structure, a plurality of claws are provided in the fixed chuck, and the claws are used to clamp the connecting rod during the processing; a rotating motor is provided between the connecting rod channel and the fixed chuck, and the rotating motor is configured to drive the fixed chuck to rotate.

[0011] Preferably, the machining tool head of each of the turning assemblies comprises a mounting frame and a blade arranged in the mounting frame, and the rotation direction of the machining tool holder is the same as the rotation direction of the fixed chuck.

[0012] The present application also provides a control method for connecting rod external hexagonal turning processing equipment, the control method comprising the following steps: S1, starting the device, and at the same time, the feeding component lifts up the connecting rod in the material transport frame and pushes the connecting rod into the feeding channel of the feeding component;

[0013] S2, the feeding push rod at the rear end of the pushing assembly pushes the connecting rod in the feeding channel to move in the direction of the connecting rod channel, so that the connecting rod is pushed into the feeding channel;

[0014] S3, the push cylinder in the limit assembly pushes the baffle plate to move downward and fix the baffle plate, and at the same time, the pressure sensor on the baffle plate detects the pressure P it is subjected to. If P=0, it is determined that the current connecting rod does not conflict with the baffle plate, and the push cylinder continues to push the connecting rod. On the contrary, if P≠0, it is determined that the current connecting rod reaches the baffle plate, the fixed chuck locks the connecting rod, and jumps to S4 for processing;

[0015] S4, the push cylinder of the limit assembly drives the baffle plate to move upward to remove the blockage of the connecting rod, and at the same time, the fixed chuck and the processing tool holder rotate, and the processing tool holder in the turning assembly approaches the connecting rod at the connecting rod channel and processes the connecting rod;

[0016] S5. After the connecting rod is processed, the processing tool rest in the turning assembly moves away from the connecting rod. At the same time, the discharge push rod in the material pushing structure pushes the connecting rod in the connecting rod channel towards the loading and unloading structure.

[0017] S7. The transmission belt in the discharge assembly starts. The connecting rod in the connecting rod channel is pushed by the discharge push rod onto the transmission belt, and the transmission belt transports the connecting rod to the discharge table to complete the discharge.

[0018] Preferably, the step S4 further includes a processing method for the connecting rod, including the following steps: S41. Each processing tool bit in the processing tool rest detects the pressure Pd received at its end. If Pd≠0, it is determined that the current processing tool bit has not completed cutting the connecting rod, and the processing tool rest continues to cut the connecting rod. Conversely, if Pd = 0, it is determined that the current connecting rod has been cut, the processing tool rest moves away from the connecting rod, and at the same time, it jumps to S42 to continue the detection.

[0019] S42. The fixed chuck continues to rotate. At the same time, the jaws in the fixed chuck detect the pressures they receive as P1, P2, and P3 respectively. If the difference between P1, P2, and P3 is not more than 1.5, it is determined that the currently turned connecting rod is qualified. Conversely, it is determined that the current connecting rod is unqualified, and a waste mark is made on the connecting rod.

[0020] By adopting the above technical solutions, the beneficial effects are as follows: 1. By integrating the material pushing structure, the loading and unloading structure, and the turning structure, the present application realizes the full-automatic processing operation of the connecting rod. Specifically, through the cooperation of the material transporting frame, the top plate, and the loading push rod, the present application realizes the automatic sorting and loading of the connecting rod and the discharging of the finished connecting rod after processing, improving the overall processing efficiency. At the same time, in the turning assembly of the present application, the turning direction of the processing tool rest is the same as that of the fixed chuck, so that the processing tool rest performs relative movement with the connecting rod at the position where it contacts the connecting rod, further improving the processing efficiency. And before processing, the position state of the connecting rod is positioned by the limiting component, so that the reference positions of each connecting rod before processing are kept consistent, and there is no need to additionally adjust the position of the connecting rod, ensuring the processing accuracy and the product qualification rate. Moreover, during the processing of the connecting rod, through real-time pressure detection and judgment, abnormal conditions during the processing are prevented, and the qualification rate of the finished product is improved. The above structural design effectively solves the problems generated during manual intervention, improves the production efficiency, and reduces the production cost.

[0021] 2. Further, the fixed chuck of the present application jointly clamps the connecting rod through multiple jaws, and detects the eccentricity of the connecting rod through the pressure difference received by each jaw. Specifically, when the turning of the connecting rod is offset, since the externally hexagonally turned part is not located at the center position of the connecting rod, an eccentric force appears during the rotation of the connecting rod, resulting in different pressures on the jaws at different positions, which can effectively avoid the problem of asymmetry of the externally hexagon of the connecting rod. And the machining tool head can detect the pressure it receives. When the pressure it receives is abnormal, it is determined that the center position of the current end of the connecting rod is offset, that is, the shape of the externally hexagonally turned part is damaged or the externally hexagon formed by turning is not at the center position of the connecting rod, avoiding dimensional problems caused by tool wear or the hardness of the connecting rod.

[0022] 3. At the same time, after the turning process is completed, the processed connecting rod is detected by the grasping of the fixed chuck, which can automatically detect the abnormal products after processing, ensuring the qualified rate of the products. And the discharging method is realized by arranging a conveyor belt moving in the opposite direction to the feeding direction inside the feeding channel for feeding. The above setting makes the discharging component, the feeding component, the connecting rod channel and the discharging push rod relatively arranged on the same straight line. For the feeding before the connecting rod processing and the discharging of the connecting rod after processing, there is no need to adjust the positions of the various components of the equipment, which is convenient for processing, has high processing efficiency, and can prevent the connecting rod from colliding with the equipment during feeding or discharging, resulting in workpiece damage.

[0023] 4. And the turning structure can detect the pressure received by the end of each machining tool head during the processing. Specifically, since the externally hexagon of the connecting rod needs a fixed feed rate and turning speed to be formed, an externally hexagonal structure is turned on the outer surface of the connecting rod. Further, after the externally hexagonal structure of the connecting rod is turned, the machining tool head will no longer contact the current connecting rod, and the pressure value received by the machining tool head is 0. By detecting the pressure of the machining tool head, it is convenient to obtain whether the current connecting rod is processed. At the same time, the various data obtained during the processing can be stored and compared synchronously, so as to detect the state and life of the equipment, effectively preventing the equipment from malfunctioning and stopping, and having good processing effects.

[0039] Preferably, the cutting heads 45 of each turning component 42 have a mounting frame and a blade 46 arranged inside the mounting frame, and the rotating direction of the processing tool holder 44 is the same as the rotating direction of the fixed chuck 7.

[0040] The present application also provides a control method for connecting rod external hexagonal turning processing equipment, the control method comprising the following steps: S1, starting the device, and at the same time, the feeding component lifts up the connecting rod in the material transport frame and pushes the connecting rod into the feeding channel of the feeding component;

[0041] S2, the feeding push rod at the rear end of the pushing assembly pushes the connecting rod in the feeding channel to move in the direction of the connecting rod channel, so that the connecting rod is pushed into the feeding channel;

[0042] S3, the push cylinder in the limit assembly pushes the baffle plate to move downward and fix the baffle plate, and at the same time, the pressure sensor on the baffle plate detects the pressure P it is subjected to. If P=0, it is determined that the current connecting rod does not conflict with the baffle plate, and the push cylinder continues to push the connecting rod. On the contrary, if P≠0, it is determined that the current connecting rod reaches the baffle plate, the fixed chuck locks the connecting rod, and jumps to S4 for processing;

[0043] S4, the push cylinder of the limit assembly drives the baffle plate to move upward to remove the blockage of the connecting rod, and at the same time, the fixed chuck and the processing tool holder rotate, and the processing tool holder in the turning assembly approaches the connecting rod at the connecting rod channel and processes the connecting rod;

[0044] S5. After the connecting rod is processed, the processing tool holder in the turning assembly moves away from the connecting rod, and at the same time, the discharge push rod in the push structure pushes the connecting rod in the connecting rod channel to move toward the upper and lower feeding structure;

[0045] S7, the transmission belt in the discharging assembly is started, the connecting rod in the connecting rod channel is pushed onto the transmission belt by the discharging push rod, and the transmission belt transports the connecting rod to the discharging platform to complete the discharging.

[0046] Preferably, the step S4 also includes a connecting rod processing method, comprising the following steps: S41, each processing tool head in the processing tool holder detects the pressure Pd on its end, if Pd≠0, it is judged that the current processing tool head has not completed cutting the connecting rod, and the processing tool holder continues to cut the connecting rod, otherwise, if Pd=0, it is judged that the current connecting rod cutting is completed, the processing tool holder is away from the connecting rod, and jumps to S42 to continue testing;

[0047] S42, the fixed chuck keeps rotating, and at the same time, the jaws in the fixed chuck detect the pressures they are subjected to, which are P1, P2, and P3 respectively. If the difference between P1, P2, and P3 is ≯1.5, the currently turned connecting rod is judged to be qualified. Otherwise, the currently turned connecting rod is judged to be unqualified and is marked as scrap.

[0048] By integrating the material pushing structure 2, the loading and unloading structure 3, and the turning structure 4, the present application realizes the full-automatic processing operation of the connecting rod. Specifically, through the cooperation of the material transporting rack 31, the ejector plate 34, and the loading push rod 33, the present application realizes the automatic sorting and loading of the connecting rod and the discharging of the finished connecting rod after processing, improving the overall processing efficiency. At the same time, in the turning component 42 of the present application, the rotation direction of the processing tool rest 44 is the same as that of the fixed chuck 7, so that the processing tool rest 44 performs relative movement with the connecting rod at the position where it contacts the connecting rod, further improving the processing efficiency. And before processing, the position state of the connecting rod is positioned through the limiting component 5, so that the reference positions of each connecting rod before processing are kept consistent, and there is no need to adjust the position of the connecting rod additionally, ensuring the processing accuracy and the qualified rate of the product. And during the processing of the connecting rod, by performing pressure detection and judgment in real time, abnormalities during the processing are prevented, and the qualified rate of the finished product is improved.

Specifically, when the turning of the connecting rod is offset, since the turned external hexagon is not relatively located at the center position of the connecting rod, an eccentric force appears during the rotation of the connecting rod, resulting in different pressures received by the jaws at different positions, which can effectively avoid the problem of asymmetry of the external hexagon of the connecting rod. And the processing tool bit 45 can detect the pressure it receives. When the pressure it receives is abnormal, it is determined that the center position of the current end of the connecting rod is offset, that is, the shape of the turned external hexagon is damaged or the turned external hexagon is not located at the center position of the connecting rod, avoiding size problems caused by tool wear or the hardness of the connecting rod.

[0050] At the same time, after the turning processing is completed, the processed connecting rod is detected through the grasping of the fixed chuck 7, and the abnormal products after processing can be automatically detected, ensuring the qualified rate of the product. And the discharging method is realized by arranging a transmission belt 61 moving in the opposite direction to the loading direction inside the loading channel 35 for feeding.

[0051] Moreover, the turning structure 4 can detect the pressure received by the end of each cutting tool head 45 during the machining process. Specifically, since the external hexagonal turning of the connecting rod requires a fixed feed rate and turning speed, an external hexagonal structure is turned on the outer surface of the connecting rod. Further, after the turning of the external hexagonal structure of the connecting rod is completed, the cutting tool head 45 will no longer contact the current connecting rod, and the pressure value received by the cutting tool head 45 is 0. By detecting the pressure of the cutting tool head 45, it is convenient to obtain whether the current connecting rod has been machined.
