[0002] With the continuous improvement of the requirements for part processing accuracy, production efficiency, and automation level in the machining industry, the traditional workpiece clamping and tool setting methods have gradually revealed many limitations. Existing chuck processing equipment usually relies on manual operation for workpiece clamping and tool setting. The operator needs to determine the relative position between the tool and the workpiece through visual judgment, manual adjustment, or with the help of simple measuring tools.

[0003] After retrieval, the invention patent with the publication number CN117102999B discloses a processing device with an automatic tool setting chuck tooling, which only requires one shutdown to replace parts, can reduce the time wasted in replacing parts, improve work efficiency, and can process different-shaped special-shaped parts. The tooling plate can be disassembled and interchanged from the mounting plate without disassembling the chuck.

[0004] Most of the existing chuck structures in existing chuck processing equipment adopt fixed-shaped jaws, which are only suitable for workpieces of a single shape (cylindrical or specific cross-sectional shape). When changing workpieces with different outer shapes, it is often necessary to manually replace the jaws or fixture components, which is inefficient, cumbersome to operate, and there are positioning errors. The clamping method cannot be switched. When processing different workpieces, it is necessary to make human judgments, interventions, and even shutdowns to replace the fixture; in addition, usually a single-sided feeding or single-station operation mode is adopted, and the processing process must wait for the workpiece to be replaced, resulting in a long idle time of the equipment, a low processing beat, and the inability to synchronize processing and feeding. Summary of the Invention

A sliding guide groove for corresponding to the clamping part one is arranged on the end surface of the chuck. A spring one is installed inside the guide groove. One end of the spring one is fixed to the clamping part one. A clamping part for the square workpiece to be clamped is arranged on the end surface of the clamping part one, and a fitting part for the cylindrical workpiece to be clamped is arranged on the inner wall surface of the clamping part one.

[0010] A further technical improvement of the present invention is that: a driving part driven by a bevel gear is arranged on the end surface of the chuck, and the driving part is threadedly sleeved with an installation seat at the bottom of the driving seat.

[0011] A further technical improvement of the present invention is that: docking seats are installed on both sides of the moving frame, and a sealing abutting component for contacting the square workpiece or the cylindrical workpiece is arranged at the end of the inner wall surface of the docking seat in a lifting manner; The sealing abutting component includes two groups of lifting units, and sealing parts adapted to the square workpiece or the cylindrical workpiece are respectively installed at the driving ends of each group of lifting units.

[0012] A further technical improvement of the present invention lies in that linear guide rails are rotatably installed on both sides of the top of the moving frame, a pushing unit is installed on the slide seat outside the linear guide rail, and a milling cutter and a chamfering cutter for processing are respectively provided at the pushing ends of the two pushing units.

[0013] A further technical improvement of the present invention lies in that a second clamping member for positioning the other end of a square or cylindrical workpiece is embedded on the inner wall surface of the docking seat.

[0014] A further technical improvement of the present invention lies in that there are four second clamping members, and the four second clamping members slide along the rail grooves in the docking seat. A slope is provided on the end face of the second clamping member close to the workpiece, and a locking portion is provided inside the end face of the second clamping member. A limiting portion is provided on the inner wall surface of the second clamping member; A trigger sensor for judging that the workpiece is inserted in place and clamped is provided at the inner wall end of the docking seat.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the clamping switching assembly, when the workpiece is cylindrical, due to the sliding of the driving seat, the arc portion at the end of the second positioning portion drives the clamping of the outer part of the cylindrical workpiece; the armature in the electromagnet pushes the connecting rod to extend. At this time, the key block portion connected by the connecting rod reaches the card slot in the first positioning portion from the card slot in the second positioning portion, realizing the clamping connection between the driving seat and the first positioning portion. The connecting rod slides in the slideway and drives the contact portion at the end of the first positioning portion to clamp the square workpiece, realizing the effective positioning and clamping of the four sides of the square workpiece. Through this clamping switching assembly, the chuck can automatically select a suitable positioning component for clamping according to the shape of the workpiece, with strong structural versatility. The clamping action switching does not require manual replacement of the jaws, and the two clamping states do not interfere with each other; 2. The moving frame slides on the base (to the left) to approach the other end face of the workpiece, and then the center of the right chuck continues to feed. The moving frame slides to the right, the workpiece on the left is completed and continues to be fed, while the right side continues to be processed, in an alternating operation mode, thus effectively avoiding the downtime waiting during the processing, and improving the processing rhythm and overall efficiency of the equipment; 3. By setting the sealing abutting assembly, when processing the workpiece, different lifting units are opened according to the shape of the workpiece, and the corresponding lifting units drive the corresponding sealing portions to closely fit with the square workpiece or the cylindrical workpiece, thereby ensuring the sealing effect of the processing; 4. When processing a workpiece, according to the processing sequence of milling first and then chamfering, an accurate reference plane and dimensional boundaries are formed through milling. When chamfering, based on this boundary, the chamfer width is ensured. By identifying the current position of the workpiece, following the rotation of the linear guide rail, the circumferential angle is changed to achieve automatic alignment with the workpiece posture, and sliding on the linear guide rail enables the milling tool and the chamfering tool to reach the target machining position on the end face of the workpiece, that is, precise tool setting is achieved. And through the pushing unit, the forward machining of the milling tool and the chamfering tool can be ensured. 5. When the end face of the workpiece is inserted into the second clamping member, the four second clamping members move outward along the rail groove, driving the plug-in board connected to them to slide synchronously. The trigger board on the plug-in board finally contacts the trigger sensor, so that the system detects that the workpiece has been inserted in place and is effectively clamped, ensuring that subsequent machining operations are started on the premise of the reliable position of the workpiece. When receiving a signal, machining is performed to avoid misoperation. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] To further elaborate on the technical means and effects adopted by the present invention to achieve the intended invention purpose, the following, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation manners, structures, features and their effects of the present invention as follows.

[0020] Please refer to Figures 1-7 As shown, the present invention provides a chuck positioning processing device for automatic tool setting, including fixing frames 1 arranged on both sides of a base. A moving frame 3 is slidably arranged between the two fixing frames 1. A chuck 2 is fixedly installed on the side surface of the fixing frame 1. A central hole 12 is arranged in the middle of the surface of the chuck 2, and a clamping unit for adaptively positioning one end of a square or cylindrical workpiece is arranged on the inner wall surface of the chuck 2. Three driving seats 13 are slidably installed on the surface of the chuck 2, and a clamping switching assembly is installed on each driving seat 13; A sliding side plate 10 is arranged on the outer side of each driving seat 13. A positioning part one 16 and a positioning part two 17 are respectively slidably arranged in the sliding side plate 10. A contact part for contacting the square workpiece is arranged on the end surface of the positioning part one 16, and an arc part for contacting the cylindrical workpiece is arranged on the end surface of the positioning part two 17; The clamping switching assembly includes an electromagnet 14 embedded in the driving seat 13, and an armature in the electromagnet 14 is connected with a plugging column; The plugging column includes a connecting rod 22, and a key block part 21 is arranged on one side of the end of the connecting rod 22; Slots 18 are arranged on the surfaces of both the positioning part one 16 and the positioning part two 17, and a slideway 19 communicating with the slot 18 is arranged on the surface of the positioning part two 17; The key block part 21 is pushed by the connecting rod 22 and slides from one slot 18 into another slot 18; When processing the workpiece, refer to Figure 1 As shown, the end face positions of cylindrical and square-structured workpieces are both positioned and loaded into the central hole 12 by the clamping unit, and then the three driving seats 13 on the chuck 2 move simultaneously towards the same center; Before the non-moving state, that is, initially, refer to Figure 3 and Figure 4 As shown, the positioning part one 16 and the positioning part two 17 are in a vertically parallel state and are both located in the sliding side plate 10; According to the shape of the workpiece (square or cylindrical), the clamping switching assembly switches to different positions so that the positioning part one 16 or the positioning part two 17 positions and clamps the workpiece; When the workpiece is cylindrical, the electromagnet 14 does not work. At this time, the key block part 21 connected by the connecting rod 22 is clamped in the slot 18 in the positioning part two 17. Due to the sliding of the driving seat 13, the arc part at the end of the positioning part two 17 clamps the outside of the cylindrical workpiece. The three driving seats 13 work simultaneously to ensure the consistency of clamping; When installing a square workpiece, the electromagnet 14 starts to work, that is, the armature in the electromagnet 14 pushes the connecting rod 22 to extend. At this time, the key block part 21 connected to the connecting rod 22 reaches the slot 18 in the first positioning part 16 from the slot 18 in the second positioning part 17, realizing the clamping of the driving seat 13 and the first positioning part 16. When the driving seat 13 slides, the connecting rod 22 slides in the slideway 19, avoiding the movement interference with the first positioning part 16, and driving the contact part at the end of the first positioning part 16 to clamp the square workpiece, realizing the effective positioning and clamping of the four sides of the square workpiece. Through this clamping switching component, the chuck 2 automatically selects a suitable positioning component for clamping according to the shape of the workpiece, with strong structural versatility. The clamping action switching does not require manual replacement of the jaws, and the two clamping states do not interfere with each other; Immediately afterwards, the moving frame 3 slides (to the left) on the base, so that the moving frame 3 approaches the other end face of the cylindrical or square structural workpiece. Then, another set of workpieces continues to be loaded onto the center of the chuck 2 on the other fixed frame 1. Machining and loading work simultaneously without the need to stop the machine; when the moving frame 3 slides to the right, the workpiece on the left is completed with machining and loading, while the machining continues on the right, forming a set of continuous cyclic machining processes, realizing the alternating operation mode of machining on the left and loading on the right, or machining on the right and loading on the left, thus effectively avoiding the downtime waiting during the machining process and improving the machining beat and overall efficiency of the equipment.

[0021] Refer to Figure 4 As shown, two sliding grooves 11 are provided on the surface of the sliding side plate 10. Sliders 20 are installed on the surfaces of the first positioning part 16 and the second positioning part 17. The sliders 20 are slidably arranged with the sliding grooves 11, and an elastic member connected to the sliding grooves 11 is provided at one end of the slider 20; Initially, the first positioning part 16 and the second positioning part 17 are kept parallel, and the connected elastic members are all in the elastic free state. The first positioning part 16 and the second positioning part 17 both slide in the two sliding grooves 11 in the sliding side plate 10, driving the corresponding elastic members to undergo elastic expansion and contraction. Through the guiding sliding, the guiding effect of their sliding is ensured, and the stability effect is increased.

[0022] Refer to Figure 2 As shown, the clamping unit includes a plurality of first clamping members 7. A sliding guiding groove 5 for corresponding to the first clamping members 7 is provided on the end face of the chuck 2. A first spring 6 is installed inside the guiding groove 5. One end of the first spring 6 is fixed to the first clamping member 7. A clamping part 8 into which a square workpiece is inserted is provided on the end face of the first clamping member 7, and a fitting part 9 into which a cylindrical workpiece is inserted is provided on the inner wall surface of the first clamping member 7; When installing a cylindrical workpiece, the workpiece directly pushes against the fitting part 9. At this time, the first clamping member 7 slides in the guiding groove 5 and compresses the first spring 6; When installing a square workpiece, the end face of the workpiece is inserted by four corresponding clamping parts 8. The openings of the clamping parts 8 face outward. When the workpiece enters, it pushes against the clamping parts 8, thereby driving the first clamping part 7 to slide in the guide groove 5, so as to adapt to the positioning of the end face of the square or cylindrical workpiece.

[0023] Refer to Figure 3 As shown, the end face of the chuck 2 is provided with a driving part 15 driven by bevel gears. The driving part 15 is threadedly sleeved with the mounting seat at the bottom of the driving seat 13. The corresponding driving seat 13 is driven to move by the driving part 15, and the three driving seats 13 move synchronously, that is, move towards or away from the center at the same time, ensuring the consistency of the movement.

[0024] Refer to Figure 1 and Figure 6 As shown, docking seats 4 are installed on both sides of the moving frame 3. Sealing abutting components that contact the square workpiece or the cylindrical workpiece are arranged at the end parts of the inner wall surfaces of the docking seats 4 in a lifting manner. The sealing abutting components include two groups of lifting units 28. Sealing parts 29 adapted to the square workpiece or the cylindrical workpiece are respectively installed at the driving ends of each group of lifting units 28. When the moving frame 3 slides horizontally in the direction of the base, it drives the docking seat 4 to cover the other end part of the workpiece. Different lifting units 28 are opened according to the shape of the workpiece. The corresponding sealing parts 29 are driven by the corresponding lifting units 28 to closely fit the square workpiece or the cylindrical workpiece, so as to ensure the sealing effect of the processing.

[0025] Refer to Figure 6 As shown, linear guide rails 23 are rotatably installed on both sides of the top of the moving frame 3. A pushing unit 24 is installed on the slide seat outside the linear guide rail 23. The pushing unit 24 uses a micro electric push rod. Milling cutters and chamfering cutters for processing are respectively arranged at the pushing ends of the two pushing units 24. Industrial cameras are installed on the mounting seats of the milling cutters and the chamfering cutters. Through the industrial camera, the current position of the workpiece is identified, it rotates following the linear guide rail 23, changes the circumferential angle, realizes automatic alignment with the workpiece posture, and slides on the linear guide rail 23, so that the milling cutter and the chamfering cutter reach the target processing position on the end face of the workpiece, that is, realizes automatic and accurate tool setting. And through the pushing unit 24, it can ensure the forward processing of the milling cutter and the chamfering cutter. The processing sequence for both shaped workpieces is milling first and then chamfering. After milling, an accurate reference plane and size boundary are formed. When chamfering, based on this boundary, the chamfer width is ensured.

[0026] Refer to Figure 6 and Figure 7As shown in the figure, a second clamping member 25 for positioning the other end of a square or cylindrical workpiece is embedded in the inner wall surface of the docking seat 4; There are four second clamping members 25, and the four second clamping members 25 are distributed in a cross-symmetrical manner and are located within the docking seat 4. Moreover, the four second clamping members 25 slide radially along the rail grooves within the docking seat 4. The end face of the second clamping member 25 close to the workpiece is provided with a slope, and a locking portion is provided inside the end face of the second clamping member 25. A limiting portion is provided on the inner wall surface of the second clamping member 25; A trigger sensor 26 for determining that the workpiece is inserted in place and clamped is provided at the inner wall end of the docking seat 4. A second spring 27 is installed outside the second clamping member 25. One end of the second spring 27 is connected to a plugging plate 30, and a trigger plate in contact with the trigger sensor 26 is installed on one plugging plate 30; The second clamping member 25 is also applicable to clamping the other end face of two types of (cylindrical and square) workpieces. During the clamping process, the cylindrical workpiece reaches the inner wall surface of the second clamping member 25 through the slope, causing the four second clamping members 25 to slide outward within the docking seat 4, and the end face of the workpiece is blocked by the limiting portion; Since one end face of the square workpiece has been positioned, the other end face abuts against the locking portion, causing the four second clamping members 25 to slide outward, improving the coaxiality of the workpiece and the stability of the end face fitting; During the sliding process, the second clamping member 25 moves outward along the rail groove under the action of the workpiece insertion force, driving the plugging plate 30 connected thereto to slide synchronously. The trigger plate on the plugging plate 30 finally contacts the trigger sensor 26, so that the system detects that the workpiece has been inserted in place and is effectively clamped, ensuring that subsequent processing operations are started on the premise that the position of the workpiece is reliable. The processing is carried out when the signal is received, avoiding misoperation.

[0027] When the present invention is in use, by setting a clamping switching assembly, when the workpiece is cylindrical, due to the sliding of the driving seat 13, the arc portion at the end of the second positioning portion 17 drives the clamping of the outer part of the cylindrical workpiece; the armature in the electromagnet 14 pushes the connecting rod 22 to elongate. At this time, the key block portion 21 connected to the connecting rod 22 reaches the slot 18 in the first positioning portion 16 from the slot 18 in the second positioning portion 17, realizing the clamping connection between the driving seat 13 and the first positioning portion 16. The connecting rod 22 slides in the slideway 19 and drives the contact portion at the end of the first positioning portion 16 to clamp the square workpiece, realizing the effective positioning and clamping of the four sides of the square workpiece. Through this clamping switching assembly, the chuck 2 automatically selects a suitable positioning component for clamping according to the shape of the workpiece, with strong structural versatility. The clamping action switching does not require manual replacement of the jaws, and the two clamping states do not interfere with each other; The moving frame 3 slides (leftward) on the base, approaching the other end face of the workpiece. Then, the center of the right chuck 2 continues to feed the workpiece. The moving frame 3 slides to the right. The workpiece on the left is completed and processed while continuing to feed, and the right side continues to be processed in an alternating operation mode, thus effectively avoiding downtime waiting during the processing and improving the processing rhythm and overall efficiency of the equipment; By providing a sealing abutting component, when processing the workpiece, different lifting units 28 are opened according to the shape of the workpiece, and the corresponding sealing parts 29 are driven by the corresponding lifting units 28 to closely fit the square workpiece or the cylindrical workpiece, thereby ensuring the sealing effect of the processing; When processing the workpiece, according to the processing sequence of milling first and then chamfering, an accurate reference plane and dimensional boundary are formed through milling. When chamfering, based on this boundary, the chamfering width is ensured. By identifying the current position of the workpiece, it rotates along the linear guide rail 23, changes the circumferential angle, and realizes automatic alignment with the posture of the workpiece. Then, it slides on the linear guide rail 23 so that the milling cutter and the chamfering cutter reach the target processing position on the end face of the workpiece, that is, accurate tool setting is achieved. And through the pushing unit 24, it can ensure the forward processing of the milling cutter and the chamfering cutter; When the end face of the workpiece is inserted into the second clamping part 25, the four second clamping parts 25 move outward along the rail groove, driving the plug-in board 30 connected to them to slide synchronously. The trigger board on the plug-in board 30 finally contacts the trigger sensor 26, so that the system detects that the workpiece has been inserted in place and is effectively clamped, ensuring that the subsequent processing actions are started on the premise of the reliable position of the workpiece. When receiving the signal, the processing is carried out to avoid misoperation.
