Description

Technical Field

[0001] The invention relates to the technical field of workpiece processing, and in particular to a combined processing lathe. Background Art

[0002] Lathe processing is a part of mechanical processing. It is to fix the workpiece and perform precision processing through high-speed rotation of the workpiece and lateral and longitudinal movement of the turning tool.

[0003] However, in the prior art, many workpieces, including non-standard workpieces, need to be processed at both ends of the workpieces, such as rod parts. This requires the processing end of the workpiece to be turned around. One method is to manually clamp the workpiece with a hook and then turn it around. This method is likely to cause the workpiece angle to shift during the turn control. After one end of some workpieces is processed, the relative position of the other end that needs to be processed needs to correspond one to one. However, when turning it around by using a grab hook, the workpiece is offset due to the lack of support on the outside, making it difficult to make the axis of the workpiece the same after it is turned, thereby affecting the coaxiality of the two ends after processing, and further affecting the quality of product production. The resulting error will affect the work The use of parts, and manual use of the hook is also very cumbersome and inconvenient, and it is impossible to turn the workpiece quickly, accurately and effectively. Another method is to use a double-end processing lathe. This type of machine tool has changed the traditional process of first processing one end of the part and then turning around to process the other end. However, the existing double-end turning machine tools all use a single spindle drive to clamp the middle of the workpiece for rotation processing, which leads to a large change in the processing length range, and the clamping position will affect the processing, and effective and accurate processing cannot be achieved. At the same time, for a small number of non-standard workpieces, the double-end lathe is used for processing, and it is also necessary to readjust the process, which is costly. Therefore, it is still chosen to be used in conjunction with manual labor.

[0004] Therefore, a combined processing lathe is proposed, which can quickly and accurately switch the two ends of the workpiece. Summary of the invention

After reaching the set position, the driving unit continues to move upward through the transmission member to drive the connecting member, and the connecting member causes the bottom shell, the transmission rod and the fixing clip to rotate synchronously by 180 degrees.

[0008] Furthermore, the driving unit includes a round shaft fixedly connected to the output end of the telescopic cylinder, a connecting spring connected between the round shaft and the support frame, and a bar tooth clamped on the top of the round shaft. The round shaft is located inside one end of the support frame, and the connecting spring is a strong spring.

[0010] Furthermore, the transmission member includes a shaft rotatably connected to the top of the support frame, a pawl clamped at one end of the shaft, a sleeve shaft rotatably connected to the top of the support frame, a wheel claw arranged at an equal angle inside one end of the sleeve shaft, a spur gear clamped at the other end of the shaft, and a first bevel gear clamped at the other end of the sleeve shaft.

[0011] The ratchet pawl is in contact with the wheel pawl, the bar teeth are meshed with the spur gear, the gear transmission ratio of the bar teeth and the spur gear is one to two, the first helical gear is meshed with the second helical gear and the transmission ratio of the two is one to one.

[0012] Furthermore, the support frame includes a sleeve connected to the connecting spring, a flat frame with one end clamped to the sleeve, and a controller arranged inside the sleeve. The round shaft is located inside the sleeve, and the controller is located above the connection between the round shaft and the connecting spring. The controller is electrically connected to the telescopic cylinder.

[0013] Furthermore, a guide rod is provided inside the bottom shell, the fixing clamp is slidably connected to the outside of the guide rod, a rotating shaft sleeve is provided on the top of the bottom shell, a slot is provided in the middle of the top of the bottom shell, and the length of the slot is greater than the length of the transmission rod.

The transmission rod and the fixed clamp are automatically clamped through a single drive, and automatic rotation is achieved through transmission through the transmission member. Very precise positioning and control can be achieved to ensure that the workpiece can be accurately positioned to the correct processing position during the U-turn process, thereby ensuring the consistency and accuracy of the processing at both ends. The automated U-turn process is faster and the workpiece clamping and workpiece rotation actions can be completed in a short time, thereby saving the processing cycle, improving production efficiency, reducing the need for manual operation, and reducing errors introduced by human operation. Precise control can reduce minor errors caused by re-clamping the workpiece.

[0020] Different workpieces are fixed by controlling the transmission rod and the fixing clamp, and the spring is connected to ensure that the workpiece is rotated after being clamped, which can reduce the risk of workpiece deviation and shaking caused by insufficient or unstable clamping, thereby improving the accuracy of the production process. At the same time, workpieces of different sizes can be reliably clamped through the control of the telescopic cylinder, thereby improving the flexibility and adaptability of production, effectively reducing the time for adjusting and calibrating the clamped workpiece, and saving clamping time and procedures.

[0021] By integrating the clamping and rotation functions of the transmission rod and the fixing clamp through a single telescopic cylinder, the operator only needs to use one control unit to complete all necessary operations, which reduces the complexity of the operation and the possibility of operating errors. The operator can complete the control of the clamping and rotation of the workpiece through simple operating steps, while simplifying the maintenance and repair process of the equipment, thereby reducing the overall cost.

DETAILED DESCRIPTION

[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0034] Example 1, reference Figure 1-9, which is the first embodiment of the present invention, provides a combined processing lathe, including a processing bed 1, and also includes a mounting shell 2 slidably connected to the outside of the processing bed 1, a bottom shell 3 rotatably connected to the bottom of the mounting shell 2, a telescopic cylinder 4 fixedly connected to the inside of the mounting shell 2, a driving unit 5 clamped at the output end of the telescopic cylinder 4, a support frame 6 slidably connected to the inside of the mounting shell 2, a transmission member 7 rotatably connected to the inside of the support frame 6, a connecting member 8 rotatably connected to the bottom of the support frame 6, and a clamping member 9 slidably connected to the inside of the bottom shell 3, the driving unit 5 is connected to the support frame 6, the two ends of the transmission member 7 are respectively engaged with the support frame 6 and the connecting member 8, and the clamping member 9 is connected to the bottom end of the connecting member 8.

[0035] The clamping member 9 includes a transmission rod 91 with one end hinged to one side of the bottom end of the connecting member 8, and a fixing clip 92 slidably connected to the inside of the bottom shell 3. The other end of the transmission rod 91 is hinged to the top end of the fixing clip 92. Two transmission rods 91 and two fixing clips 92 are provided and are symmetrical about the central axis of the connecting member 8. The driving unit 5 moves upward and drives the transmission rod 91 upward through the connecting member 8, so that the transmission rod 91 drives the two fixing clips 92 to slide toward the central axis of the connecting member 8. After reaching the set position, the driving unit 5 continues to move upward and drives the connecting member 8 through the transmission member 7. The connecting member 8 causes the bottom shell 3, the transmission rod 91 and the fixing clip 92 to rotate synchronously by 180 degrees.

[0036] Among them, when the transmission rod 91 is pulled by the connecting member 8, since the mounting shell 2 will not move, and the bottom shell 3 cannot move, the bottom shell 3 limits the position of the transmission rod 91, so that the transmission rod 91 can only translate inside the bottom shell 3, thereby realizing the movement of the two transmission rods 91 and the fixing clamp 92, so that the workpiece is locked and clamped by the fixing clamp 92, and then rotated, so that the clamping force is evenly and stably applied to the workpiece, ensuring that the workpiece maintains a stable shape and position during rotation, thereby ensuring the processing accuracy and quality.

[0037] Optionally, the rotation is controlled by electric current and fixed with a cylinder, but this method requires manual control of different drives, and the motor is directly installed at the output end of the cylinder during the initial design to provide accurate rotational force. However, this method is affected by the spatial arrangement when installing auxiliary structures such as reducers, and it is unable to effectively control the position changes of the motor and the cylinder. It is very susceptible to the influence of the auxiliary structure, causing serious interference to the processing, and when in use, manual experience is required to observe whether the fixture is clamped on the workpiece, which still results in errors.

[0038] Specifically, by integrating and avoiding external power supply and control systems, control through a single telescopic cylinder 4 can reduce the number of control devices and save the space occupied by the equipment. This is especially important for processing sites with limited range of activities, and can make the production space more compact and efficiently utilize the space.

[0039] Reference Figure 2-4 The driving unit 5 includes a round shaft 51 fixedly connected to the output end of the telescopic cylinder 4, a connecting spring 52 connected between the round shaft 51 and the support frame 6, and a gear 53 clamped on the top of the round shaft 51. The round shaft 51 is located inside one end of the support frame 6, and the connecting spring 52 is a strong spring.

[0040] Specifically, the round shaft 51 is connected to the support frame 6 through the supporting force of the connecting spring 52, and when the round shaft 51 moves upward, it will drive the support frame 6 to move upward synchronously. At the same time, there is an air pressure state between the round shaft 51 and the support frame 6. When the support frame 6 cannot move, the round shaft 51 will squeeze the connecting spring 52, and the round shaft 51 can still move inside the support frame 6, and the support frame 6 will not block the round shaft 51.

[0041] Reference Figure 2-4 The connecting member 8 includes a round sleeve rod 81 rotatably connected to the middle part of the support frame 6, and a second bevel gear 82 clamped on the top end of the round sleeve rod 81. The bottom end of the round sleeve rod 81 is hinged with two transmission rods 91, and the second bevel gear 82 is meshed with the transmission member 7, so as to serve as an intermediate transmission structure. The upward movement of the round sleeve rod 81 will drive the second bevel gear 82 and the transmission rod 91. Similarly, the rotation of the round sleeve rod 81 also drives the second bevel gear 82 and the transmission rod 91, so that the transmission rod 91 receives the power support provided by the telescopic cylinder 4.

[0042] Reference Figure 3-5 The transmission member 7 includes a shaft 71 rotatably connected to the top of the support frame 6, a pawl 72 clamped at one end of the shaft 71, a sleeve shaft 73 rotatably connected to the top of the support frame 6, a wheel claw 74 arranged at an equal angle inside one end of the sleeve shaft 73, a spur gear 75 clamped at the other end of the shaft 71, and a first bevel gear 76 clamped at the other end of the sleeve shaft 73. The wheel claw 74 is composed of a spring and an arc-shaped claw, and the sleeve shaft 73 and the wheel claw 74 form a ratchet structure similar to that of the ratchet.

[0043] Among them, taking the surface of one end of the pawl 72 as the main perspective, the spur gear 75 rotates counterclockwise when driven by the bar teeth 53, and the pawl 72 also rotates counterclockwise synchronously. The pawl 72 will therefore engage with the wheel claw 74, so that the wheel claw 74 drives the sleeve shaft 73 and the first bevel gear 76 to rotate. However, when the bar teeth 53 move downward, it will drive the spur gear 75 to rotate clockwise, and the pawl 72 will rotate clockwise. At this time, due to the concave angle of the wheel claw 74, the wheel claw 74 will only be squeezed by the pawl 72 and cannot transmit. This makes the transmission rod 91 rotate only once, and the workpiece also rotates only once, accurately changing the processing end.

[0044] The pawl 72 is fitted with the wheel claw 74, the bar teeth 53 is meshed with the spur gear 75, the gear transmission ratio of the bar teeth 53 and the spur gear 75 is one to two, the first bevel gear 76 is meshed with the second bevel gear 82, and the transmission ratio of the two is one to one.

[0045] Specifically, when the spur gear 75 is driven by the upward movement of the bar teeth 53, the support frame 6 is affected by the workpiece and cannot move. As the bar teeth 53 drives the spur gear 75 to rotate half a circle, the shaft 71 and the pawl 72 will be driven synchronously, and then the pawl 72 drives the sleeve shaft 73 and the first bevel gear 76 to rotate through the wheel claw 74. The first bevel gear 76 is driven to rotate one hundred and eighty degrees. When the first bevel gear 76 rotates, it drives the second bevel gear 82 and the circular sleeve rod 81 to rotate. The circular sleeve rod 81 is connected to the transmission rod 91 and the fixing clamp 92, which causes the workpiece and the bottom shell 3 to rotate one hundred and eighty degrees.

[0046] Reference Figure 2-7 The support frame 6 includes a sleeve 61 connected to the connecting spring 52, a flat frame 62 with one end engaged with the sleeve 61, and a controller 63 arranged inside the sleeve 61. The round shaft 51 is located inside the sleeve 61, and the controller 63 is located above the connection between the round shaft 51 and the connecting spring 52. This allows the round shaft 51 to quickly squeeze the controller 63 when moving inside the sleeve 61. The controller 63 is electrically connected to the telescopic cylinder 4, causing the telescopic cylinder 4 to stop driving.

[0047] The spur gear 75 is engaged with the bar teeth 53 and the circular shaft 51 is moved upwards by the sleeve 61. When the circular shaft 51 is restricted by the workpiece and cannot move, the bar teeth 53 will drive the spur gear 75. However, the chuck 102 still fixes the workpiece and the workpiece cannot rotate. The spur gear 75 cannot be driven by the bar teeth 53 either, so the bar teeth 53 is also restricted. Therefore, when the circular shaft 51 does not move inside the sleeve 61, the position of the top of the bar teeth 53 is at a certain distance from the spur gear 75. At the same time, the controller 63 is located above the connection between the circular shaft 51 and the connecting spring 52. The distance between the controller 63 and the connection position is equal to the distance from the top of the bar teeth 53 to the spur gear 75. The circular shaft 51 can move to a certain extent to trigger the controller 63 to prevent jamming and prevent parts collision. At this time, the workpiece can be locked by the chuck 102.

[0048] Specifically, the telescopic cylinder 4 can utilize the existing technology in conjunction with the solenoid valve, and two switches can be set at the control panel position of the main body 101, which can be divided into a and b. Pressing switch a can control the telescopic cylinder 4 to start moving upward. When the circular shaft 51 triggers the controller 63, the telescopic cylinder 4 automatically stops. Then, pressing switch a again can make the telescopic cylinder 4 rise to the highest point, and pressing switch b can make the telescopic cylinder 4 move downward. When moving downward, the circular shaft 51 triggers the controller 63 and will not stop driving the telescopic cylinder 4 until the telescopic cylinder 4 moves down to the lowest point and stops automatically. Manual control of the two switches is required to achieve clamping and rotation of the workpiece and control the movement of the mounting shell 2 at the same time. The left and right movement of the mounting shell 2 can be achieved by setting a ball screw in the existing technology in the main body 101.

[0049] It is understandable that when the arc clamp 922 fixes the workpiece, the driving unit 5 automatically reaches the set position, and at this time, the telescopic cylinder 4 will automatically stop squeezing the controller 63 because the round shaft 51 reaches the set position.

[0050] Reference Figure 2-4 A guide rod 31 is provided inside the bottom shell 3, and a fixing clip 92 is slidably connected to the outside of the guide rod 31. A rotating shaft sleeve 32 is provided on the top of the bottom shell 3. A strip notch 10 is provided in the middle of the top of the bottom shell 3. The length of the strip notch 10 is greater than the length of the transmission rod 91, thereby ensuring that when one end of the transmission rod 91 is pulled, the end of the transmission rod 91 moves up and does not contact the inner wall of the bottom shell 3, and the bottom of the mounting shell 2 at this position is not provided with a thin wall, which will not cause obstruction to the transmission rod 91. When the fixing clip 92 and the transmission rod 91 rotate, since the fixing clip 92 is located outside the guide rod 31, and the two sides of the fixing clip 92 slide inside the bottom shell 3, the fixing clip 92 drives the bottom shell 3 to rotate when it rotates.

[0051] Reference Figure 2-6 The fixing clamp 92 is divided into a left clamp 9201 and a right clamp 9202. The fixing clamp 92 includes a slider 921 slidably connected to the outside of the guide rod 31, and an arc clamp 922 clamped at the bottom end of the slider 921. Two arc clamps 922 are clamped at the bottom of the left clamp 9201, and one arc clamp 922 is clamped at the bottom of the middle of the right clamp 9202. The length between the two arc clamps 922 is equal to the width of a single arc clamp 922.

[0052] Specifically, when the slider 921 and the arc clamp 922 move with the transmission rod 91, the two sliders 921 provide sufficient support for the workpiece, and different numbers of arc clamps 922 are set under different sliders 921, and the arc clamps 922 are staggered to avoid collision when the arc clamps 922 are fixed to the workpiece.

[0053] Reference Figure 1-4The top notch 22 is provided with a top groove 22 on one side of the mounting shell 2, and the top groove 22 is located directly above the bar tooth 53. Since the bar tooth 53 will move up with the circular shaft 51, the top groove 22 is used to provide a moving space for the bar tooth 53. In addition, a protective cover can also be provided at the position of the top groove 22. If the mounting shell 2 is raised as a whole, it will waste materials and costs. Therefore, the top groove 22 can provide a moving space for the bar tooth 53. The mounting shell 2 is provided with a mounting sleeve 23 on the outside of the bottom shell 3. One end of the flat frame 62 is slidably connected to the outside of the positioning rod 21, which means that one side of the support frame 6 is stabilized by the circular shaft 51, and the other side is stabilized by the positioning rod 21, thereby ensuring that the support frame 6 moves up and down smoothly without deviation. The rotating shaft sleeve 32 is rotatably connected to the inside of the mounting sleeve 23, thereby providing support for the rotation of the bottom shell 3. The connection between the two is similar to installing a bearing between the two, and other methods can also be used to ensure that the bottom shell 3 can rotate.

[0054] Reference Figure 1-9 The processing bed 1 includes a main body 101, a chuck 102 rotatably connected to the output end of the main body 101, a turning tool 103 and a positioning member 104 slidably connected to the top of the main body 101, the chuck 102 is located on the left side of the turning tool 103, and the positioning member 104 is located on the right side of the turning tool 103. The mounting shell 2 is placed on the rightmost side of the main body 101 when not in use to avoid affecting the processing of the workpiece. The diameter of the arc clamp 922 is larger than the diameter of the chuck 102, so that it can cope with all sizes of workpieces that can be processed by the processing bed 1. A plurality of serrations 9221 are arranged inside the arc clamp 922 to further increase the fixing effect.

[0055] The working principle of the present invention is as follows: the workpiece is clamped by the chuck 102, and then the positioning member 104 is moved to stabilize the workpiece, and then one end of the workpiece is processed by controlling the turning tool 103. After completion, the turning tool 103 is retracted, and the mounting shell 2 is controlled to translate by the main body 101, and the mounting shell 2 is translated to a position roughly in the middle of the workpiece, and then the circular shaft 51 is driven to move upward by controlling the telescopic cylinder 4. The circular shaft 51 drives the sleeve 61 and the flat plate frame 62 to move upward synchronously through the connecting spring 52. At this time, the flat plate frame 62 drives the circular sleeve rod 81 and the second bevel gear 82 to move upward synchronously, and the circular sleeve rod 81 then pulls the top ends of the two transmission rods 91, and the transmission rod 91 is limited by the bottom shell 3 and the guide rod 31, and the transmission rod 91 is then pulled by the circular sleeve rod 81. After that, it moves along the path of the guide rod 31, and the two transmission rods 91 drive the slider 921 and the arc clamp 922 to move toward the workpiece position. When the two arc clamps 922 clamp the workpiece, the two arc clamps 922 are in contact with the workpiece and cannot move, so the round sleeve rod 81 and the second bevel gear 82 are restricted in movement, and the flat frame 62 and the sleeve 61 are also restricted by the round sleeve rod 81 and the second bevel gear 82. At this time, the round shaft 51 cannot drive the sleeve 61 to move, so the round shaft 51 will compress the connecting spring 52 after being pushed, and the round shaft 51 will move inside the sleeve 61. The round shaft 51 triggers the controller 63, so that the telescopic cylinder 4 stops driving, and then releases the lock of the chuck 102 on the workpiece, driving the mounting shell 2 to drive the arc The clamp 922 drives the workpiece to move to an unobstructed rotatable area, and then the telescopic cylinder 4 is started again to drive the circular shaft 51, and the circular shaft 51 drives the bar teeth 53 to move, and the bar teeth 53 drives the spur gear 75 to rotate, and the spur gear 75 drives the shaft rod 71 and the ratchet 72 to rotate, and the ratchet 72 is fitted with the wheel claw 74, and when the ratchet 72 rotates, the wheel claw 74 is used to rotate unidirectionally, and the ratchet 72 is then meshed with the wheel claw 74, so that the wheel claw 74 drives the sleeve shaft 73 to rotate, and the sleeve shaft 73 synchronously rotates the first bevel gear 76, and the first bevel gear 76 is meshed with the second bevel gear 82, so that the second bevel gear 82 is driven by the first bevel gear 76 to drive the circular sleeve rod 81 to rotate, and the circular sleeve rod 81 makes the two bottom ends The transmission rod 91 rotates, and the transmission rod 91 is transmitted to the slider 921 and the arc clamp 922, so that the two drive the bottom shell 3 and the workpiece to rotate 180 degrees, and then the mounting shell 2 is moved to insert the processed end of the workpiece into the inside of the chuck 102 for fixation. At this time, the round shaft 51 is pulled by the telescopic cylinder 4, and the round shaft 51 moves down. However, due to the strong elastic force of the connecting spring 52, the sleeve 61 will not move during the descent of the round shaft 51. At this time, the round shaft 51 also pulls the bar teeth 53 to drive the spur gear 75 when moving, but the rotation of the spur gear 75 drives the shaft rod 71 and the ratchet 72 to rotate. Since the ratchet 72 squeezes the surface of the wheel claw 74 when rotating, the two cannot mesh, and the rotation force cannot be transmitted to the workpiece position.As the round shaft 51 continues to move downward, the connecting spring 52 is no longer compressed, and the sleeve 61 and the flat frame 62 also move downward. The flat frame 62 drives the round sleeve rod 81 and the second bevel gear 82 to move downward. The round sleeve rod 81 makes one end of the two transmission rods 91 move downward, so the two transmission rods 91 are squeezed from the middle, so that the other ends of the two transmission rods 91 gradually move away from each other. The transmission rod 91 then drives the bottom slider 921 and the arc clamp 922 away from the workpiece. At this time, after separating from the workpiece, the part is moved to an area that does not affect the processing by moving the mounting shell 2, and then the turning tool 103 continues to process.
