Description

Technical Field

[0001] This utility model belongs to the field of lathes, and in particular relates to an automatic turning mechanism for lathes used for machining rotating shafts. Background Technology

[0002] An automatic workpiece flipping mechanism for lathe machining of shaft components is disclosed. This mechanism enables automatic workpiece flipping, thereby improving machining efficiency and accuracy. The automatic flipping mechanism mainly comprises a flipping device and a control system. The flipping device achieves the workpiece flipping action through a mechanical transmission mechanism, while the control system controls the movement of the flipping device through programming to ensure the precise position and angle of the workpiece during the flipping process. The advantage of this automatic flipping mechanism is its ability to achieve rapid and precise workpiece flipping, thus improving lathe machining efficiency and accuracy.

[0003] The existing automatic tilting mechanism for lathes used in machining shaft parts presents numerous problems in actual production scenarios. The main operational inconvenience stems from the cumbersome control logic, often requiring complex training for operators to master its operation. For example, adjusting the clamping angle of a part necessitates repeatedly switching parameters between multiple control panels, lacking intuitive visual guidance. Novice operators are highly prone to setting incorrect parameters, leading to part clamping misalignment or tilting angle deviation. Utility Model Content

[0004] The purpose of this utility model is to provide an automatic turning mechanism for lathes used for machining rotating shaft parts. By meshing the driving gear on the rotating shaft with the driven gear on the rotating shaft, the existing automatic turning problem is solved.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is an automatic turning mechanism for lathes used for machining rotating shaft parts, including a spindle box, a support base fixedly connected to the bottom of the spindle box, a bed fixedly connected to the side of the spindle box, a tailstock slidably connected to the top of the bed, a telescopic support frame fixedly connected to the top of the spindle box, and an automatic turning device provided on the telescopic support frame.

[0007] The automatic flipping device includes a support plate, the side of which is fixedly connected to the top of the telescopic support frame. A motor is fixedly connected to the side of the support plate, and a pulley is fixedly connected to the output shaft of the motor. A belt is provided on the circumferential surface of the pulley. A rotating shaft is rotatably connected through the top of the telescopic support frame. A pulley is fixedly connected to the circumferential surface of the rotating shaft, and a drive gear is fixedly connected to the circumferential surface of the rotating shaft. A driven gear is fixedly connected to the circumferential surface of the rotating shaft.

[0008] Furthermore, the driving gear and the driven gear mesh with each other, and the first pulley is connected to the circumferential surface of the second pulley via a belt drive. The belt drive has a buffering and shock absorption function, which can reduce the impact when the motor starts and improve the stability during operation. The gear meshing transmission has high precision, ensuring the accuracy of the workpiece flipping angle.

[0009] Furthermore, an electric telescopic rod is fixedly connected to one end of the rotating shaft, and an adjustable clamp is fixedly connected to one end of the electric telescopic rod. The electric telescopic rod, in conjunction with the adjustable clamp, allows for control and adjustment of the clamping position and force, adapting to rotating shafts of different diameters and lengths. The electric telescopic rod can adjust the overall movement trajectory for vertical movement.

[0010] Furthermore, the top of the adjustable clamp is located at the bottom of the electric telescopic rod, a chuck is rotatably connected to the side of the spindle box, and a baffle is fixedly connected to the top of the bed. The chuck provides clamping for the workpiece, ensuring its rigidity during machining, while the baffle prevents cutting debris from splashing.

[0011] Furthermore, a lubrication device is provided at the top of the telescopic support frame. The lubrication device includes a rotating column, the bottom of which is fixedly connected to the top of a rotating shaft. A sliding plate is slidably connected to the circumferential surface of the rotating column. A limit plate is slidably connected to one end of the sliding plate. A lubrication box is fixedly connected to the side of the telescopic support frame. A pressure plate is slidably connected to the inner wall of the lubrication box. A spring is fixedly connected to the side of the pressure plate. One end of the spring is fixedly connected to the inner wall of the lubrication box.

[0012] Furthermore, the side of the limiting slide plate has a groove, the top of the limiting plate has a groove, and the top of the bed is slidably connected to a tool holder. The groove of the limiting slide plate and the groove of the limiting plate ensure the stability of the sliding plate's movement trajectory and improve the reliability of the lubrication device 7.

[0013] Furthermore, a fine-tuning handle is rotatably connected to the side of the tool holder, and six springs are arranged in a linear array on the side of the pressure plate. The tool holder, in conjunction with the fine-tuning handle, enables high-precision position adjustment, and the six linearly arrayed springs ensure even force distribution on the pressure plate, guaranteeing stable lubricant output.

[0014] This utility model has the following beneficial effects:

[0015] This utility model's automatic flipping device transmits rotational motion to the rotating shaft through the meshing of a driving gear on the rotating shaft and a driven gear on the rotating shaft. This ultimately drives the workpiece held by the electric telescopic rod and adjustable clamp to flip, enabling the switching of processing on different sides of the workpiece on the rotating shaft. The modular design integrates support, processing, and flipping functions, resulting in a compact structure and high stability. The electric telescopic rod and telescopic support frame can adapt to the processing needs of workpieces of different heights. The automatic flipping device replaces manual flipping, improving the degree of automation and reducing manual labor intensity.

[0016] This utility model lubrication device automatically triggers the lubrication process through the linkage of an automatic flipping device, eliminating the need for manual lubrication, reducing operational intensity, and adapting to the automated machining needs of lathes. In addition, the lubricant is released only when the rotating shaft moves, i.e. during the workpiece flipping process, and when the friction of key components intensifies, avoiding waste caused by continuous lubrication and improving the utilization rate of lubricant.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The automatic tilting device 6 includes a support plate 61, the side of which is fixedly connected to the top of the telescopic support frame 5. A motor 62 is fixedly connected to the side of the support plate 61. A pulley 63 is fixedly connected to the output shaft of the motor 62.

A rotating shaft 68 is rotatably connected through the top of the telescopic support frame 5. A driven gear 69 is fixedly connected to the circumferential surface of the rotating shaft 68.

[0029] As shown in the figure, the driving gear 67 and the driven gear 69 mesh with each other, and pulley 63 is connected to the circumference of pulley 66 via belt 64. Belt drive has a buffering and shock absorption function, which can reduce the impact when the motor 62 starts and improve the stability during operation. The gear meshing transmission has high precision, ensuring the accuracy of the workpiece flipping angle.

[0030] As shown in the figure, one end of the rotating shaft 68 is fixedly connected to an electric telescopic rod 11, and the other end of the electric telescopic rod 11 is fixedly connected to an adjustable clamp 12. The electric telescopic rod 11, in conjunction with the adjustable clamp 12, allows for control and adjustment of the clamping position and force, adapting to rotating shafts of different diameters and lengths. The electric telescopic rod 11 can adjust the overall movement trajectory for vertical movement.

[0031] As shown in the figure, the top of the adjustable clamp 12 is located at the bottom of the electric telescopic rod 11, the side of the spindle box 1 is rotatably connected to the chuck 8, and the top of the bed 13 is fixedly connected to the baffle 4.

[0032] As shown in the figure, a lubrication device 7 is provided on the top of the telescopic support frame 5. The lubrication device 7 includes a rotating column 71, the bottom of which is fixedly connected to the top of the rotating shaft 68. A sliding plate 72 is slidably connected to the circumferential surface of the rotating column 71. A limiting slide plate 73 is slidably connected to one end of the sliding plate 72. A lubrication box 74 is fixedly connected to the side of the telescopic support frame 5. A pressure plate 75 is slidably connected to the inner wall of the lubrication box 74.

[0034] As shown in the figure, a fine-tuning handle 10 is rotatably connected to the side of the tool holder 9. Six springs 76 are arranged in a linear array on the side of the pressure plate 75. The tool holder 9, in conjunction with the fine-tuning handle 10, can achieve high-precision position adjustment. The six linearly arrayed springs 76 ensure that the pressure plate 75 is subjected to uniform force, guaranteeing stable lubricating oil output.

[0035] One specific application of this embodiment is as follows: The automatic flipping device 6 is used to realize the automated flipping operation of the workpiece. When the workpiece needs to be flipped, the motor 62 fixed to the side of the support plate 61 is started. The output shaft of the motor 62 drives the pulley 63 fixedly connected to it to rotate synchronously. The pulley 63 transmits power to the pulley 66 through the belt 64 set on its circumferential surface, so that the pulley 66 rotates synchronously with the pulley 63. Since the pulley 66 is fixed on the circumferential surface of the rotating shaft 65, and the rotating shaft 65 rotates on the top of the telescopic support frame 5, the rotation of the pulley 66 drives the rotating shaft 65 to rotate synchronously on the telescopic support frame 5 along its axis. When the rotating shaft 65 rotates, the drive gear 67 fixedly connected to its circumferential surface... The rotating shaft 68 rotates synchronously with the rotating shaft 65. Since the driving gear 67 and the driven gear 69 mesh with each other, and the driven gear 69 is fixedly connected to the circumferential surface of the rotating shaft 68, which also passes through and is rotatably connected to the top of the telescopic support frame 5, the rotation of the driving gear 67 drives the driven gear 69 to rotate through gear meshing transmission, thereby driving the rotating shaft 68 to rotate along its axis on the telescopic support frame 5. The rotation of the rotating shaft 68 directly drives the electric telescopic rod 11 and the adjustable clamp 12, which are fixedly connected to one end of it, to rotate synchronously, ultimately realizing the automated rotation action of the workpiece held by the adjustable clamp 12. By controlling the forward and reverse rotation and output speed of the motor 62, the rotation angle and rotation speed of the workpiece can be precisely adjusted to adapt to the needs of different processing conditions. For shaft-type workpieces of different lengths, the telescopic support frame 5 can change the distance between the adjustable clamp 12 and the rotating shaft 68 by extending or shortening it, ensuring that the clamp can accurately align with the clamping point of the workpiece. In conjunction with the adjustment structure of the adjustable clamp 12, the adaptability range of the device to workpieces of different specifications is further expanded. As a key component that directly contacts the workpiece, the core function of the adjustable clamp 12 is to achieve precise clamping and release of the workpiece through opening and closing actions. Through its own jaw opening and closing mechanism, the opening and closing range can be adjusted according to the diameter of different shaft parts, so as to achieve stable clamping of workpieces of various specifications and solve the problem of insufficient adaptability of single-specification clamps.

[0036] The lubrication device 7 is used to automatically lubricate the key moving parts of the automatic tilting device 6. Its operation relies on mechanical linkage. When the rotating shaft 68 rotates under the drive of the automatic tilting device 6, the rotating column 71 fixed to the top of the rotating shaft 68 rotates synchronously with it. Since the circumferential surface of the rotating column 71 slides in contact with the sliding plate 72, the rotation of the rotating column 71 will push the sliding plate 72 to slide horizontally along the groove on the top of the limiting plate 78. The limiting plate 78 is fixed to the top of the telescopic support frame 5, which plays a guiding role. When the sliding plate 72 slides, the limiting slide plate 73 at one end pushes the pressure plate 75 in the lubrication box 74 through the side groove, so that the pressure plate 75 moves into the lubrication box 74 and compresses the spring 76. Its other end is fixed to the inner wall of the lubrication box 74. At this time, the pressure plate 75 exerts pressure on the lubricant, such as lubricating oil, in the lubrication tank 74, forcing the lubricant to flow out through the oil outlet pipe 77 on the side of the lubrication tank 74. The oil outlet end of the oil outlet pipe 77 is equipped with a sealing port, which will only open when a certain pressure is generated, and then drip precisely onto easily worn parts such as the meshing joint of the driving gear 67 and the driven gear 69. When the pressure plate 75 and the sliding plate 72 are no longer in contact after rotating to a certain angle, the spring 76 returns to its initial position, waiting for the next lubrication. In addition, the lubricant is released only when the rotating shaft 68 moves, i.e., during the workpiece flipping process, when the friction of key components intensifies, avoiding waste caused by continuous lubrication and improving the utilization rate of lubricant.
