The rotating shaft is hinged on both sides of the slide, the axis arm swings at one end of the rotating shaft, the hinge is hinged on the inner side of the axis arm, and the sliding column is located at the end of the axis arm away from the rotating shaft.

[0018] As a further solution of the present invention: the rotating shaft is connected to the upper end of the shaft arm, the shaft arms are distributed on both sides of the lower end of the slide, the shaft arms are grouped in pairs, and each group of shaft arms is diamond-shaped, and a sliding column is connected to the connection point of each group of shaft arms, and the shaft arms are arranged vertically as a whole.

[0023] As a further solution of the present invention: the transformation method comprises the following steps. The specific operation steps are as follows:

[0024] S1: Place the part on the upper end of the clamping frame, which can clamp the part, and manually lift the slide upward. The upper end of the shaft arm swings synchronously through the rotating shaft. At this time, the distance between the shaft arms on both sides of the slide is reduced, and the hinge in the middle of the shaft arm is spaced from the inner wall of the track. The hinge cannot assist the slide to be tightly connected to the inner wall of the track.

[0025] S2: When the slide moves upward, the lining plate moves upward at the lower end of the inner wall of the track. The lining plate drives the sliding column to move downward in the slide slot of the slide through the connecting rod by utilizing the weight of the lining plate. After the sliding column slides downward, it can stretch to the lower end of the shaft arm. The shaft arm is stretched vertically as a whole, thereby further reducing the distance between the hinges and the shaft arms on both sides of the slide;

[0026] S3: Therefore, the entire slide needs to be manually lifted up, and then slide on the inner side of the track, and then push the slide, the lower end of the slide slides on the inner side of the track, and the transmission frame and the clamping frame slide synchronously when the slide slides. After the adjustment is completed, move the slide downward;

[0027] S4: When the slide moves downward, the slide can assist the lower end of the lining plate to fit with the lower end of the inner wall of the track. When the lining plate is in a stationary state, the connecting rod at the upper end of the lining plate can be squeezed to the lower end of the sliding column, thereby assisting the sliding column to slide upward in the slide groove of the slide, and the sliding column slides upward;

[0028] S5: The shaft arm moves toward the inside of the track as a whole. Since the space inside the track is limited, the shaft arm is compressed in the space inside the track, and the shaft arms at both ends of the hinge swing synchronously. Since the shaft arm is arranged vertically as a whole and the middle part of the shaft arm is hinged, the shaft arm can swing in opposite directions, and then the two ends of the shaft arm can swing in opposite directions;

[0029] S6: At this time, the distance between the shaft arms on both sides of the slide increases, and the hinge can form a horizontal contact with the inner wall of the track. When the slide slides downward, the shaft arms and the hinge are deformed as a whole, and the lower end of the slide is embedded in the track;

[0030] S7: Manually operate the control panel. The control panel controls the drive motor to start. The drive motor drives tool 1 and tool 2 to rotate respectively. The tool heads at one end of tool 1 and tool 2 can process both sides of the part at the same time. Beneficial Effects

[0031] 1. Manual operation control panel, the control panel controls the drive motor to start, the drive motor drives tool 1 and tool 2 to rotate respectively, the tool heads at one end of tool 1 and tool 2 can process both sides of the part at the same time, tool 1 and tool 2 are arranged inside the lathe, so that the internal mechanical transmission of the lathe is transformed, and the tool changing device of the current CNC machine tool is dismantled, which solves the problem of special machine tool processing, makes the processing more flexible, and solves the disadvantages of single-axis processing of CNC machine tools, so that the lathe can realize simultaneous processing of both sides;

[0032] 2. Place the parts on the upper end of the clamping frame, which can clamp the parts. Manually lift the slide upwards, then push the slide, and the lower end of the slide slides on the inner side of the track. When the slide slides, the transmission frame and the clamping frame slide synchronously. After the adjustment is completed, move the slide downward. At this time, the lower end of the slide is embedded in the track, which can facilitate manual adjustment of the position of the parts on the upper end of the clamping frame, thereby facilitating the rapid turning of the parts by tool 1 and tool 2.

[0033] 3. When the slide moves downward, the shaft arm moves toward the inside of the track as a whole. Due to the limited space inside the track, the shaft arm is compressed in the space inside the track, and the shaft arms at both ends of the hinge swing synchronously. Since the shaft arms are arranged vertically as a whole and the middle of the shaft arms are hinged with hinges, the shaft arms can swing in opposite directions, and then the two ends of the shaft arms can swing in opposite directions. At this time, the distance between the shaft arms on both sides of the slide increases, and the hinge can form a horizontal contact with the inner wall of the track. When the slide slides downward, the shaft arm and the hinge are deformed as a whole, which can assist the slide to be tightly connected to the inner side of the track, thereby avoiding the movement of the slide during the turning process of tool 1 and tool 2;

[0034] 4. When the carriage moves upward, the upper end of the shaft arm swings synchronously through the rotating shaft. At this time, the distance between the shaft arms on both sides of the carriage is reduced, and the hinge in the middle of the shaft arm is spaced from the inner wall of the track. The hinge cannot assist the carriage to be tightly connected to the inner wall of the track. Therefore, the carriage as a whole needs to be manually lifted up and then slide on the inner side of the track.

[0035] 5. When the slide moves downward, the slide can assist the lower end of the lining plate to fit with the lower end of the inner wall of the track. When the lining plate is in a stationary state, the connecting rod at the upper end of the lining plate can be squeezed to the lower end of the sliding column, thereby assisting the sliding column to slide upward inside the slide slot of the slide. The sliding column slides upward, which can further assist the distance between the shaft arms on both sides of the slide to increase, thereby assisting the inner hinge of the shaft arm to fit tightly with the inner wall of the track;

[0036] 6. When the slide moves upward, the lining plate moves upward at the lower end of the inner wall of the track. Using the weight of the lining plate, the lining plate drives the sliding column to move downward inside the slide groove of the slide through the connecting rod. After the sliding column slides downward, it can stretch to the lower end of the shaft arm, and the shaft arm is stretched vertically as a whole, thereby further reducing the hinges on both sides of the slide and the distance between the shaft arms.

[0058] Among them: the transmission frame 3 and the clamping frame 301, the transmission frame 3 is installed on the upper end of the slide 4 by bolts, when the slide 4 slides horizontally, the transmission frame 3 slides synchronously, the clamping frame 301 is concave, and the parts are placed on the upper end of the clamping frame 301;

[0059] The parts are placed on the upper end of the clamping frame 301, and the parts are parts that need to be turned;

[0060] A slide 4, a slide groove is provided on one side of the lower end of the slide 4, the slide groove is arranged vertically, and a limiting mechanism is provided at the lower end of the slide 4;

[0061] The slide 4 needs to be pushed manually to facilitate the lower end of the slide 4 to slide inside the track 103;

[0062] Among them: the part is placed on the upper end of the clamping frame 301, the clamping frame 301 can clamp the part, and the slide 4 is manually taken upward, and then the slide 4 is pushed, and the lower end of the slide 4 slides on the inner side of the track 103. When the slide 4 slides, the transmission frame 3 and the clamping frame 301 slide synchronously. After the adjustment is completed, the slide 4 is moved downward. At this time, the lower end of the slide 4 is embedded in the inside of the track 103, which can facilitate manual adjustment of the position of the part on the upper end of the clamping frame 301, thereby facilitating the rapid turning of the part by the tool 1 2 and the tool 2 201;

[0063] Example 3: Please refer to the attached manual Figure 7-9 It can be seen that the difference between Example 3 and Examples 1 and 2 is that the limiting mechanism includes a rotating shaft 401, an axis arm 402, a hinge 403 and a sliding column 404, the rotating shaft 401 is hinged to both sides of the slide 4, the axis arm 402 swings at one end of the rotating shaft 401, the hinge 403 is hinged to the inner side of the axis arm 402, and the sliding column 404 is located at the end of the axis arm 402 away from the rotating shaft 401;

[0064] Among them: the rotating shaft 401 and the shaft arm 402, the rotating shaft 401 is connected to the upper end of the shaft arm 402, the shaft arm 402 is distributed on both sides of the lower end of the slide 4, the shaft arms 402 are grouped in pairs, and each group of shaft arms 402 is in a diamond shape, and the connection of each group of shaft arms 402 is connected with a sliding column 404, and the shaft arms 402 are arranged vertically as a whole;

[0065] The rotating shaft 401 is connected to the upper end of the shaft arm 402, and the shaft arm 402 can be conveniently swung at an angle of 25-90° through the rotating shaft 401;

[0066] The shaft arms 402 are grouped in pairs, and each group of shaft arms 402 is in a diamond shape. Figure 8 and 9 As shown;

[0067] Hinge 403, hinge 403 is hinged at the middle of shaft arm 402, shaft arms 402 at both ends of hinge 403 swing in opposite directions, hinge 403 is arranged in three sections, two of which are connected to shaft arms 402 respectively;

[0068] The hinge 403 is provided in three sections, two of which are respectively connected to the shaft arms 402, so that the shaft arms 402 at both ends of the hinge 403 can swing in opposite directions.

[0069] When the slide 4 moves downward, the shaft arms 402 at both ends of the hinge 403 swing in opposite directions, so that the two ends of the shaft arms 402 can swing in opposite directions. At this time, the distance between the shaft arms 402 on both sides of the slide 4 increases. Figure 8 As shown, the hinge 403 can form a horizontal contact with the inner wall of the track 103;

[0070] When the carriage 4 moves upward, the upper end of the shaft arm 402 swings synchronously through the rotating shaft 401. At this time, the distance between the shaft arms 402 on both sides of the carriage 4 is reduced. Fig. 9 As shown, the hinge 403 in the middle of the shaft arm 402 is spaced apart from the inner wall of the track 103;

[0071] A sliding column 404, one end of which slides in the slide groove on the side of the slide 4, and both sides of the other end of the sliding column 404 are connected to the shaft arm 402, and the sliding column 404 slides vertically in the slide groove of the slide 4;

[0072] A slide groove is provided on one side of the lower end of the slide 4, and the slide groove is arranged vertically to limit the sliding direction of the slide column 404;

[0073] Among them: when the slide 4 moves downward, the shaft arm 402 moves toward the inside of the track 103 as a whole. Since the internal space of the track 103 is limited, the shaft arm 402 is compressed in the internal space of the track 103, and the shaft arms 402 at both ends of the hinge 403 swing synchronously. Since the shaft arms 402 are arranged vertically as a whole and the middle part of the shaft arms 402 is hinged with the hinge 402, the shaft arms 402 can swing in opposite directions, and then the two ends of the shaft arms 402 can swing in opposite directions. At this time, the distance between the shaft arms 402 on both sides of the slide 4 increases, and the hinge 403 can form a horizontal tight contact with the inner wall of the track 103. When the slide 4 slides downward, the shaft arm 402 and the hinge 403 are deformed as a whole, which can assist the slide 4 to be tightly connected to the inner side of the track 103, thereby avoiding the movement of the slide 4 during the turning process of the tool 1 2 and the tool 2 201;

[0074] When the slide 4 moves upward, the upper end of the shaft arm 402 swings synchronously through the rotating shaft 401. At this time, the distance between the shaft arms 402 on both sides of the slide 4 is reduced, and the hinge 403 in the middle of the shaft arm 402 is spaced from the inner wall of the track 103. The hinge 403 cannot assist the slide 4 to be tightly connected to the inner wall of the track 103. Therefore, the slide 4 as a whole needs to be manually lifted up and then slide on the inner side of the track 103.

[0075] Example 4: Please refer to the attached manual Figure 7-9 It can be seen that the difference between Example 4 and Examples 1-3 is that the limiting mechanism further includes a connecting rod 405 and a lining plate 406, the connecting rod 405 is slidably connected to the lower end of the sliding column 404, and the lining plate 406 slides on the lower end of the connecting rod 405;

[0076] Among them: connecting rod 405 and lining plate 406, lining plate 406 runs through the bottom of the slide 4, lining plate 406 is located on the inner side of the track 103, lining plate 406 is linked with the sliding column 404 through connecting rod 405, and the weight of lining plate 406 is 200-300g;

[0077] When the slide 4 moves downward, the slide 4 can assist the lower end of the lining plate 406 to fit with the lower end of the inner wall of the track 103. When the lining plate 406 is in a stationary state, the connecting rod 405 at the upper end of the lining plate 406 can be squeezed to the lower end of the sliding column 404, thereby assisting the sliding column 404 to slide upward inside the slide groove of the slide 4. The sliding column 404 slides upward, which can further assist the distance between the shaft arms 402 on both sides of the slide 4 to increase, thereby assisting the inner hinge 403 of the shaft arm 402 to fit tightly with the inner wall of the track 103.

[0078] When the slide 4 moves upward, the lining plate 406 moves upward at the lower end of the inner wall of the track 103. With the weight of the lining plate 406, the lining plate 406 drives the sliding column 404 to move downward inside the slide slot of the slide 4 through the connecting rod 405. After the sliding column 404 slides downward, it can stretch to the lower end of the shaft arm 402. The shaft arm 402 is vertically stretched as a whole, so that the distance between the hinges 403 and the shaft arm 402 on both sides of the slide 4 can be further reduced. Example

[0079] The transformation method includes the following steps:

[0080] S1: Place the part on the upper end of the clamping frame 301, which can clamp the part, and manually take the slide 4 upward, the upper end of the shaft arm 402 swings synchronously through the rotating shaft 401, and the distance between the shaft arms 402 on both sides of the slide 4 is reduced. The hinge 403 in the middle of the shaft arm 402 is spaced from the inner wall of the track 103, and the hinge 403 cannot assist the slide 4 to be tightly clamped on the inner wall of the track 103;

[0081] S2: When the slide 4 moves upward, the lining plate 406 moves upward at the lower end of the inner wall of the track 103. With the weight of the lining plate 406, the lining plate 406 drives the sliding column 404 to move downward inside the slide groove of the slide 4 through the connecting rod 405. After sliding downward, the sliding column 404 can be stretched to the lower end of the shaft arm 402, and the shaft arm 402 is stretched vertically as a whole, so that the distance between the hinges 403 and the shaft arm 402 on both sides of the slide 4 can be further reduced;

[0082] S3: Therefore, the entire slide 4 needs to be manually lifted up, and then slides on the inner side of the track 103, and then pushes the slide 4, the lower end of the slide 4 slides on the inner side of the track 103, and when the slide 4 slides, the transmission frame 3 and the clamping frame 301 slide synchronously. After the adjustment is completed, the slide 4 is moved downward;

[0083] S4: When the slide 4 moves downward, the slide 4 can assist the lower end of the lining plate 406 to fit with the lower end of the inner wall of the track 103. When the lining plate 406 is in a stationary state, the connecting rod 405 at the upper end of the lining plate 406 can be pressed to the lower end of the sliding column 404, thereby assisting the sliding column 404 to slide upward in the sliding groove of the slide 4, and the sliding column 404 slides upward;

[0084] S5: The shaft arm 402 moves toward the inside of the track 103 as a whole. Since the space inside the track 103 is limited, the shaft arm 402 is compressed in the space inside the track 103, and the shaft arms 402 at both ends of the hinge 403 swing synchronously. Since the shaft arm 402 is arranged vertically as a whole and the hinge 402 is hinged in the middle of the shaft arm 402, the shaft arm 402 can swing in opposite directions, and thus the two ends of the shaft arm 402 can swing in opposite directions;

[0085] S6: At this time, the distance between the shaft arms 402 on both sides of the slide 4 increases, and the hinge 403 can form a horizontal contact with the inner wall of the track 103. When the slide 4 slides downward, the shaft arms 402 and the hinge 403 are deformed as a whole, and the lower end of the slide 4 is embedded in the track 103.

[0086] S7: Manually operate the control panel 101, the control panel 101 controls the drive motor 102 to start, and the drive motor 102 drives the tool 1 2 and the tool 2 201 to rotate respectively, and the tool heads 202 at one end of the tool 1 2 and the tool 2 201 can process both sides of the part at the same time.

[0087] The above are only preferred embodiments of the present invention. It should be pointed out that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present invention. These should also be regarded as the protection scope of the present invention. These will not affect the effect of the implementation of the present invention and the practicality of the patent.

3. A method for modifying a bidirectional outer diameter turning CNC machine tool, characterized in that: The modification method of the bidirectional outer diameter turning CNC machine tool according to any one of claims 1-2 comprises the following steps: S1: The part is placed on the upper end of the clamping frame (301), and the clamping frame (301) is capable of clamping the part, while the slide (4) is manually lifted upward, and the upper ends of the shaft arms (402) are synchronously swung through the rotating shaft (401). At this time, the distance between the shaft arms (402) on both sides of the slide (4) is reduced, and a distance is generated between the hinge (403) in the middle of the shaft arm (402) and the inner wall of the track (103), so that the hinge (403) cannot assist the slide (4) to be tightly connected to the inner wall of the track (103); S2: When the slide (4) moves upward, the lining plate (406) moves upward at the lower end of the inner wall of the track (103). The lining plate (406) drives the sliding column (404) to move downward inside the slide groove of the slide (4) through the connecting rod (405) by utilizing the weight of the lining plate (406). After the sliding column (404) slides downward, it can stretch to the lower end of the shaft arm (402), and the shaft arm (402) is stretched vertically as a whole, thereby further reducing the distance between the hinges (403) and the shaft arms (402) on both sides of the slide (4); S3: Therefore, the entire slide (4) needs to be manually lifted upwards, and then slides on the inner side of the track (103), and then the slide (4) is pushed, and the lower end of the slide (4) slides on the inner side of the track (103). When the slide (4) slides, the transmission frame (3) and the clamping frame (301) slide synchronously. After the adjustment is completed, the slide (4) is moved downwards; S4: When the slide (4) moves downward, the slide (4) can assist the lower end of the lining plate (406) to fit with the lower end of the inner wall of the track (103); when the lining plate (406) is in a stationary state, the connecting rod (405) at the upper end of the lining plate (406) can be pressed to the lower end of the sliding column (404), thereby assisting the sliding column (404) to slide upward inside the sliding groove of the slide (4), and the sliding column (404) slides upward; S5: the shaft arm (402) moves as a whole toward the inside of the track (103). Since the space inside the track (103) is limited, the shaft arm (402) is compressed in the space inside the track (103), and the shaft arms (402) at both ends of the hinge (403) swing synchronously. Since the shaft arm (402) is arranged vertically as a whole and the hinge (403) is hinged in the middle of the shaft arm (402), the shaft arm (402) can swing in opposite directions, and thus the two ends of the shaft arm (402) can swing in opposite directions. S6: At this time, the distance between the shaft arms (402) on both sides of the slide (4) increases, and the hinge (403) can form a horizontal contact with the inner wall of the track (103). When the slide (4) slides downward, the shaft arms (402) and the hinge (403) are deformed as a whole, and at this time, the lower end of the slide (4) is embedded in the interior of the track (103); S7: manually operating the control panel (101), the control panel (101) controls the driving motor (102) to start, the driving motor (102) drives the tool 1 (2) and the tool 2 (201) to rotate respectively, and the tool heads (202) at one end of the tool 1 (2) and the tool 2 (201) can process both sides of the part at the same time.
