DETAILED DESCRIPTION

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of specific embodiments of the present invention.

[0034] Please refer to Figures 1 to 10 As shown:

[0036] Among them, the control rod b302 and the driving sprocket 305 are both provided with synchronous tooth grooves 3051, and one end of the rod body of the contact rod 304 is provided with a synchronous gear 3041, and the synchronous gear 3041 is inserted into the synchronous tooth groove 3051. In use, when the contact rod 304 is not pressed by external force, the multi-control component 3 is in a reset state. At this time, the control rod a301 or the control rod b302 can be rotated alone to realize the movement operation of the moving seat 201, so as to realize the moving feeding operation of the blank clamped and positioned on the positioning component 4. One end of the control rod a301 is provided with a single control gear a3011, and the control rod b One end of 302 is provided with a single-control gear b3021, the frame cross section of the holder 303 is designed in an "L" shape, and the bottom of the horizontal frame of the holder 303 is rotatably connected to the functional gear 3031, and the gear teeth on both sides of the functional gear 3031 are respectively engaged with the gear teeth of the single-control gear a3011 and the single-control gear b3021 for transmission. Taking the rotation of the control rod a301 alone as an example, when the control rod a301 is rotated alone, the single-control gear a3011 of the control rod a301 can drive the single-control gear b3021 to reverse synchronously through the functional gear 3031 (that is, the control rod b302 will also reverse synchronously with the control rod a301), and the multi-control group When the member 3 is in the reset state, the locking top spring 2022 synchronously inserts the synchronous gear 3041 of the contact rod 304 into the synchronous tooth groove 3051 of the driving sprocket 305 and the single-control gear b3021 through the locking block 202. That is, at this time, the single-control gear b3021 and the driving sprocket 305 are used as a whole and the motion state of this whole is always the same, so that when the single-control gear b3021 rotates, it can drive the driving sprocket 305 to rotate synchronously under the cooperation of the synchronous gear 3041 and the synchronous tooth groove 3051, and when the driving sprocket 305 rotates, it can drive the moving sprocket 306 to rotate through the chain. The screw 102 is fixedly installed inside the guide seat 101, so that the guide screw 102 can never rotate on its own. When the moving sprocket 306 rotates, it can move outside the guide screw 102 through the rod thread of the guide screw 102, so that the moving sprocket 306 can drive the moving seat 201 to move synchronously and change the use position when moving, thereby completing the feed adjustment operation of the blank during the hollow metal tube processing operation, and the above operation can also be achieved when the control rod b302 is rotated alone. When the control rod b302 is rotated alone, the control rod a301 will rotate synchronously with the control rod b302 in the opposite direction. It is convenient and flexible to use, and the adjustment is fast and efficient.

[0037] Among them, a locking tooth groove 3032 is provided inside the rotating shaft of the retaining frame 303, and a locking gear 2021 is provided on the side of the locking block 202 facing the retaining frame 303, the locking gear 2021 is inserted into the locking tooth groove 3032, and one end of the abutting rod 304 abuts against the side of the locking gear 2021. This design makes it possible for the multi-control component 3 to be in the reset state, because the retaining frame 303 cannot rotate by itself, so that at this time, only synchronous reverse rotation can be achieved between the control rod a301 and the control rod b302, and synchronous and unidirectional rotation operation cannot be achieved. The use is stable and interference between the two adjustment methods is avoided. The use is stable. The multi-control component 3 is in the reset state and the positioning component 4 is in the self-locking state, thereby avoiding the phenomenon of accidental loosening of the positioning component 4 when adjusting the use position of the moving component 2. Occurs, when the multi-control component 3 is in the reset state, at this time, under the action of the locking top spring 2022, the locking gear 2021 is inserted into the locking tooth groove 3032, the side of the locking block 202 is provided with a positioning groove 2023, and the interior of the moving seat 201 is provided with a positioning block 2011, and the positioning block 2011 is inserted into the interior of the positioning groove 2023. Since the locking block 202 is unable to rotate by itself under the cooperation of the positioning block 2011 and the positioning groove 2023, the locking block 202 can prevent the retaining frame 303 from rotating under the cooperation of the locking gear 2021 and the locking tooth groove 3032, thereby locking the retaining frame 303 and the driving rod 404 in the use state so that they cannot rotate, thereby realizing the function of locking the use state of the positioning component 4 in the reset state of the multi-control component 3, and the processing is stable.

[0038] Among them, a driving gear 3033 is provided outside the rotating shaft of the holder 303, and an adjusting gear 4041 is provided at one end of the driving rod 404. The gear teeth of the driving gear 3033 and the adjusting gear 4041 are engaged and transmitted. In use, the multi-control component 3 can also adjust the use state of the positioning component 4. When the use state of the positioning component 4 needs to be adjusted by the multi-control component 3, it is necessary to press and maintain the pressed state of the resistance rod 304, and then rotate the control rod a30 synchronously and in the same direction. 1 and control rod b302, when the contact rod 304 is pressed, the contact rod 304 can contact the locking gear 2021 out of the locking tooth groove 3032 through one end of the rod body, so that the retaining frame 303 can rotate freely inside the moving seat 201, because the rotation directions of the single control gear a3011 and the single control gear b3021 in normal transmission are always opposite under the action of the functional gear 3031, so when the control rod a301 and the control rod b3021 are rotated synchronously and in the same direction, 2, the single-control gear a3011 and the single-control gear b3021 cannot rotate normally independently, but the single-control gear a3011 and the single-control gear b3021 can clamp the functional gear 3031 and drive it to rotate along the rotation axis of the control rod a301 and the control rod b302, so that the functional gear 3031 can drive the retaining frame 303 to rotate synchronously when rotating along the axis of the control rod a301 and the control rod b302, and the driving gear 3033 can drive the driving rod 404 to rotate through the national adjustment gear 4041 when the retaining frame 303 rotates, and the driving rod 404 can drive the clamping screw 402 to rotate under the transmission action of the worm gear when rotating, so that the clamping screw 402 can drive the two clamping blocks 403 to move synchronously and in opposite directions through the rod body thread when rotating to realize the loosening operation of the blank, which is convenient to use, and the multi-control component 3 set at the same position can realize the operation and regulation of the moving component 2 and the positioning component 4 in different ways, which is convenient to use and improves the work efficiency.

[0039] Among them, a locking top spring 2022 is provided inside the locking block 202, and the two ends of the locking top spring 2022 are respectively against the inside of the locking block 202 and the inside of the moving seat 201. Under the action of the locking top spring 2022, when the interference rod 304 is not subjected to external force, the synchronous gear 3041 is simultaneously inserted into the synchronous tooth groove 3051 of the control rod b302 and the driving sprocket 305, and the gear outer diameter of the synchronous gear 3041 is smaller than the tooth groove inner diameter of the locking tooth groove 3032. In use, when the interference rod 304 is pressed, the synchronous gear 3041 will slip out of the synchronous tooth groove 3051 of the single-control gear b3021, thereby releasing the overall relationship between the driving sprocket 305 and the single-control gear b3021, and the locking gear The inner diameter of the groove 3032 is larger than the outer diameter of the synchronous gear 3041, so that when the single-control gear b3021 rotates driven by the control rod b302 or the control rod a301, the driving sprocket 305 will not rotate with the single-control gear b3021, so that when the use position of the positioning component 4 is adjusted, it will not interfere with the use state of the moving component 2. The two can be adjusted and used independently, and the stability is extremely strong. After the use state of the positioning component 4 is adjusted, after the resistance rod 304 is released, the resistance rod 304 can drive the locking gear 2021 and the synchronous gear 3041 to automatically reset under the action of the locking top spring 2022, so as to prepare for the subsequent adjustment of the use position of the moving component 2 through the multi-control component 3, which is easy to operate and flexible to use.

[0040] Example 2: On the basis of Example 1, the cross-section of the seat body of the moving seat 201 is "T"-shaped, and a track groove a1011 is provided inside the guide seat 101. The moving seat 201 is inserted into the track groove a1011. The track groove a1011 can limit the moving trajectory of the moving seat 201, so that the moving seat 201 will not be skewed or twisted during movement, causing the device to get stuck and fail, and the use is stable.

[0041] Example 3: On the basis of Example 1 and Example 2, the cross-sectional shape of the clamping block 403 is "T" shaped, and a track groove b4011 is provided inside the positioning seat 401, and the clamping block 403 is inserted into the track groove b4011. The track groove b4011 can limit the moving trajectory of the clamping block 403, thereby avoiding the phenomenon that the clamping block 403 is skewed or twisted during the adjustment and movement, causing the device to get stuck and fail, thereby further improving the stability of the device.

[0042] Specific usage and function of this embodiment: In the present invention, the multi-control component 3 can realize the movement and positioning of the moving component 2 and the loosening operation of the positioning component 4 on the blank. First, the blank to be processed is clamped and fixed on the positioning component 4. When it is necessary to adjust the use state of the positioning component 4 through the multi-control component 3, it is necessary to press and maintain the pressing state of the interference rod 304, and then synchronously and in the same direction The rotation control rod a301 and the control rod b302 can be used. When the interference rod 304 is pressed, the interference rod 304 can use one end of the rod body to contact the locking gear 2021 out of the locking tooth groove 3032, so that the retaining frame 303 can rotate freely inside the moving seat 201. Because the single-control gear a is under the action of the functional gear 3031 The rotation directions of 3011 and the single-control gear b3021 during normal transmission are always opposite, so that when the control rod a301 and the control rod b302 are rotated synchronously and in the same direction, the single-control gear a3011 and the single-control gear b3021 cannot rotate independently and normally, but the single-control gear a3011 and the single-control gear b3021 can clamp the functional gear 3031 and drive it to rotate along the rotation axis of the control rod a301 and the control rod b302, so that the functional gear 3031 can drive the retaining frame 303 to rotate synchronously when rotating along the axis of the control rod a301 and the control rod b302, and the driving gear 3033 can drive the driving rod 404 to rotate through the national adjustment gear 4041 when the retaining frame 303 rotates. When the worm gear is pressed, the synchronous gear 3041 will be out of the synchronous tooth groove 3051 of the single-control gear b3021, thereby releasing the overall relationship between the driving sprocket 305 and the single-control gear b3021, and the inner diameter of the locking tooth groove 3032 is larger than the outer diameter of the synchronous gear 3041, so that when the single-control gear b3021 is in the control rod b302 or the control rod b302, the synchronous gear 3041 will be out of the synchronous tooth groove 3051 of the single-control gear b3021, thereby releasing the overall relationship between the driving sprocket 305 and the single-control gear b3021, and the inner diameter of the locking tooth groove 3032 is larger than the outer diameter of the synchronous gear 3041, so that when the single-control gear b3021 is in the control rod b302 or the control rod b302, the synchronous gear 3041 will be out of the synchronous tooth groove 3051 of the single-control gear b3021, thereby releasing the overall relationship between the driving sprocket 305 and the single-control gear b3021, and the inner diameter of the locking tooth groove 3032 is larger than the outer diameter of the synchronous gear 3041, When driven by rod a301 to rotate, driving sprocket 305 will not rotate with single-control gear b3021, so that when adjusting the use position of positioning assembly 4, it will not interfere with the use state of moving assembly 2. The two can be adjusted and used independently. After the blank is fixed, the movement of moving assembly 2 is controlled by multi-control assembly 3 to realize the feeding operation of the blank during hollow metal tube processing. When the use state of positioning assembly 4 is adjusted, after releasing the resistance rod 304, the resistance rod 304 can drive the locking gear 2021 and the synchronous gear 3041 to automatically reset under the action of locking top spring 2022, so as to prepare for the subsequent adjustment of the use position of moving assembly 2 by multi-control assembly 3. When the resistance rod 304 is not pressed by external force, the multi-control assembly 3 is in a reset state.At this time, rotating the control rod a301 or the control rod b302 alone can realize the movement operation of the moving seat 201, so as to realize the moving feeding operation of the blank clamped and positioned on the positioning component 4. Taking the rotation of the control rod a301 alone as an example, when the control rod a301 is rotated alone, the single-control gear a3011 of the control rod a301 can drive the single-control gear b3021 to reverse synchronously through the functional gear 3031 (that is, the control rod b302 will also reverse synchronously with the control rod a301). When the multi-control component 3 is in the reset state, the locking top spring 2022 synchronously inserts the synchronous gear 3041 of the contact rod 304 into the driving sprocket 305 and the single-control gear b3 through the locking block 202. 021, that is, at this time, the single-control gear b3021 and the driving sprocket 305 are used as a whole and the motion state of this whole is always the same, so that when the single-control gear b3021 rotates, it can drive the driving sprocket 305 to rotate synchronously under the cooperation of the synchronous gear 3041 and the synchronous tooth groove 3051, and the driving sprocket 305 can drive the moving sprocket 306 to rotate through the chain when rotating. Since the guide screw 102 is fixedly installed inside the guide seat 101, the guide screw 102 can never rotate by itself. When the moving sprocket 306 rotates, it can move outside the guide screw 102 through the rod thread of the guide screw 102, so that the moving sprocket 306 moves when moving. It can drive the moving seat 201 to synchronously move and change the use position, so as to complete the feed adjustment operation of the blank during the hollow metal tube processing operation, and the above operation can also be achieved when the control rod b302 is rotated alone. When the control rod b302 is rotated alone, the control rod a301 will rotate synchronously with the control rod b302 in the opposite direction. When the multi-control component 3 is in the reset state, since the retaining frame 303 cannot rotate by itself, the control rod a301 and the control rod b302 can only realize synchronous reverse rotation action, and cannot realize synchronous and same-direction rotation operation. It is stable to use and avoids interference between the two adjustment methods. The multi-control component 3 is in the reset state and the positioning component 4 is in the self-locking state, so To avoid the accidental loosening of the positioning assembly 4 when adjusting the use position of the moving assembly 2, when the multi-control assembly 3 is in the reset state, the locking gear 2021 is inserted into the locking tooth groove 3032 under the action of the locking top spring 2022. Since the locking block 202 cannot rotate by itself under the cooperation of the positioning block 2011 and the positioning groove 2023, the locking block 202 can prevent the retaining frame 303 from rotating through the cooperation of the locking gear 2021 and the locking tooth groove 3032, thereby locking the use state of the retaining frame 303 and the driving rod 404 so that they cannot rotate, thereby realizing the function of locking the use state of the positioning assembly 4 in the reset state of the multi-control assembly 3.
