Description

Technical Field

[0001] The utility model relates to the technical field of mechanical processing, in particular to a numerically controlled lathe for processing an eccentric shaft. Background Art

[0002] The eccentric shaft is a special workpiece, which is characterized by the outer circle and the axis of the outer circle being parallel but not overlapping. This design enables the eccentric shaft to transmit not only rotation but also revolution when rotating. The eccentric shaft is usually composed of two main parts: the shaft and the eccentric sleeve. The shaft is usually made of metal material and is a cylindrical structure with a specific length. One section is carved into an eccentric shape to transmit force to other components. The eccentric sleeve is an annular component sleeved on the shaft, with an eccentric hole inside, which allows the eccentric sleeve to rotate on the shaft and change the distance between the shaft and the sleeve.

[0003] Eccentric shaft processing is generally completed by CNC lathes. CNC lathes use digital control systems to accurately control the processing process of workpieces. At present, when using CNC lathes to process eccentric shafts, the blanks are generally placed on a placement tray, and then the placement tray is moved to the gripping range of the CNC lathe's robotic arm. The robotic arm can then grab the blanks in the placement tray one by one and process them in the CNC lathe, and the processed eccentric shafts are placed back in the placement tray. After all the blanks in the placement tray are processed, the CNC lathe needs to be stopped or paused, and then the placement tray is removed from the gripping station of the robotic arm, and then the next placement tray with the blanks is placed in the gripping station. Such operation is more troublesome and affects the processing efficiency. Utility Model Content

[0004] In order to overcome the disadvantage that the existing processing process needs to stop the machine when replacing the blank, which affects the processing efficiency, the purpose of the utility model is to provide a CNC lathe for processing eccentric shafts that can perform continuous processing without stopping the machine.

[0005] The technical solution is: a CNC lathe for processing eccentric shafts, including a CNC lathe body, a mechanical arm, a support platform, an electric push rod, a movable plate and a receiving tray. The CNC lathe body is equipped with a mechanical arm, a support platform is connected to the middle right side of the CNC lathe body, an electric push rod is installed on the right rear side of the support platform, a movable plate is slidably arranged in the support platform, a telescopic rod of the electric push rod is connected to the movable plate, and two receiving trays are placed in the movable plate.

[0006] As a further preferred solution, slide grooves are provided on both sides of the movable plate, and strip-shaped protrusions are provided on both sides of the receiving tray, and the receiving tray is slidably matched with the slide grooves through the strip-shaped protrusions.

[0007] As a further preferred solution, it also includes legs and a placement frame. The right rear part of the support table is fixedly connected to the placement frame by bolts, a receiving tray is placed in the placement frame, and legs are installed at the bottom of the placement frame.

[0008] As a further preferred solution, it also includes a baffle, a reset spring and a handle. The upper front side of the placement frame is slidably connected with a baffle, the baffle blocks the front side of the receiving tray in the placement frame, two reset springs are connected between the baffle and the placement frame, and the top of the baffle is connected with a handle.

[0009] As a further preferred solution, a magnet is also included. The middle of the movable plate is embedded with a magnet, and the side of the receiving plate is connected with an iron block that is attracted and matched with the magnet.

[0010] As a further preferred solution, a protective cover is also included. The right side of the support table is connected to the protective cover. The electric push rod is located in the protective cover. The protective cover protects the electric push rod to prevent iron chips from falling on the electric push rod during processing and affecting its normal use.

[0011] As a further preferred solution, it also includes rollers. Five rollers are rotatably connected to the bottom of the placement frame. The rollers reduce the friction between the receiving tray and the placement frame, making it convenient to place or take the receiving tray.

[0012] As a further preferred solution, an anti-slip cover is also included. The outer side of the handle is covered with the anti-slip cover, which plays an anti-slip role and facilitates the movement of the baffle by pulling the handle.

[0013] The utility model has the following advantages: the utility model drives the movable plate to move forward and backward through the electric push rod, thereby driving the blank into the grasping range of the robot arm through the receiving tray, and the receiving tray with the processed eccentric shaft is moved out from the grasping range, at which time the corresponding receiving tray can be taken out to collect the eccentric shaft, and at the same time a new receiving tray can be placed in the movable plate, and the blanks can be arranged on this receiving tray, so that the eccentric shaft processing operation can be continuously carried out without stopping, thereby improving work efficiency; the receiving tray is placed in the placement frame, which is convenient for taking and collecting the receiving tray.

[0020] The technical solution is further described below in conjunction with specific embodiments. It should be noted that the words indicating directions such as up, down, left, and right mentioned in this article are only for the position of the structure shown in the corresponding drawings. The serial numbers of the parts in this article, such as first, second, etc., are only used to distinguish the objects described and do not have any order or technical meaning. The words such as connection and coupling in this application include direct and indirect connection (coupling) unless otherwise specified.

[0021] A CNC lathe for machining eccentric shafts, such as Figure 1 , Figure 2 and Figure 5 As shown, it includes a CNC lathe body 1, a mechanical arm 2, a support platform 3, an electric push rod 4, a movable plate 5 and a receiving tray 6. The CNC lathe body 1 is equipped with the mechanical arm 2. The middle part of the right side of the CNC lathe body 1 is connected to the support platform 3. The electric push rod 4 is installed on the right rear part of the support platform 3. A movable plate 5 is slidably arranged in the support platform 3. The telescopic rod of the electric push rod 4 is connected to the movable plate 5. Two receiving trays 6 are placed in the movable plate 5. Slide grooves 7 are arranged on the left and right sides of the movable plate 5. Strip protrusions are arranged on the left and right sides of the receiving tray 6. The receiving tray 6 slides with the slide grooves 7 through the strip protrusions.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, it also includes a support leg 8, a placement frame 801, a baffle 9, a reset spring 10, a handle 11, a roller 14 and an anti-skid sleeve 15. The right rear part of the support platform 3 is fixedly connected to the placement frame 801 by bolts. A receiving tray 6 is placed in the placement frame 801. Five rollers 14 are rotatably connected to the bottom of the placement frame 801. The rollers 14 reduce the friction between the receiving tray 6 and the placement frame 801, so as to facilitate the placement or removal of the receiving tray 6. The bottom of the placement frame 801 is equipped with a support leg 8. The upper front side of the placement frame 801 is slidably connected to the baffle 9. The baffle 9 blocks the front side of the receiving tray 6 in the placement frame 801. Two reset springs 10 are connected between the baffle 9 and the placement frame 801. The top of the baffle 9 is connected to the handle 11. The outside of the handle 11 is covered with an anti-skid sleeve 15. The anti-skid sleeve 15 plays an anti-skid role, so as to facilitate the movement of the baffle 9 by pulling the handle 11.

[0023] like Figure 4 and Figure 5 As shown, a magnet 12 is also included. The middle of the movable plate 5 is embedded with the magnet 12, and the side of the receiving plate 6 is connected with an iron block that is attracted and matched with the magnet 12.

[0024] like Figure 1 and Figure 4 As shown, a protective cover 13 is also included. The right side of the support platform 3 is connected to the protective cover 13. The electric push rod 4 is located in the protective cover 13. The protective cover 13 protects the electric push rod 4 to prevent iron filings from falling on the electric push rod 4 during processing and affecting its normal use.

[0025] In the initial state, the telescopic rod of the electric push rod 4 is in an extended state, and the moving plate 5 is located at the front position; when the eccentric shaft needs to be processed, the blank is first arranged and placed on the receiving tray 6 in front of the moving plate 5, and then the telescopic rod of the electric push rod 4 is started to shorten, thereby driving the moving plate 5 to move backward, and then the electric push rod 4 is closed. At this time, the receiving tray 6 located in front of the moving plate 5 moves into the grasping range of the robot arm 2, and the receiving tray 6 located behind the moving plate 5 moves backward out of the grasping range of the robot arm 2. At this time, the CNC lathe body 1 can be started to work, and the robot arm 2 can grab the blank on the receiving tray 6 and carry it into the CNC lathe body 1 for eccentric shaft processing operation. After the processing of this blank is completed, the robot arm 2 will move the processed blank to the receiving tray 6. The eccentric shaft is taken out and placed on the original blank placement position, and then the next blank is grabbed for processing, and this reciprocating process is repeated, and the blanks on the receiving tray 6 are processed one by one continuously. During this period, the operator arranges the blanks and places them on the receiving tray 6 behind the movable plate 5; after all the blanks on the front receiving tray 6 are processed, the telescopic rod of the electric push rod 4 is started to extend, so as to drive the receiving tray 6 to move forward through the movable plate 5, and the front receiving tray 6 drives the processed eccentric shaft to move forward out of the grasping range of the robot arm 2, and the rear receiving tray 6 drives the blank to move forward to the grasping range of the robot arm 2, so that the robot arm 2 can continue to grasp and process the blank without stopping the operation, thereby improving the processing efficiency;

[0026] The operator can then pull the handle 11 upwards to drive the baffle plate 9 to move upwards, and the return spring 10 is deformed. The baffle plate 9 no longer blocks the receiving tray 6 in the placement frame 801, and a receiving tray 6 can be pulled forwards. The handle 11 is released, and under the action of the return spring 10, the baffle plate 9 moves downwards to block the front side of the receiving tray 6 in the placement frame 801 to prevent the receiving tray 6 from accidentally falling. The taken receiving tray 6 is then placed in the front of the movable plate 5, and the magnet 12 attracts the receiving tray 6 to limit and fix the receiving tray 6. Then, the blanks are arranged and placed on the front receiving tray 6. The outer side of the blank on the rear receiving tray 6 is processed, and then the telescopic rod of the electric push rod 4 is controlled to shorten to drive the movable plate 5 to move backwards, so that the blank of the front receiving tray 6 is moved to the work station. This is repeated, and the eccentric shaft processing operation can be continuously carried out without stopping in the middle, thereby improving the processing efficiency.
