[0024] like Figures 1 to 12 As shown, this application provides an automatic tool holder assembly device 100 for assembling a first tool holder body 11 and a second tool holder body 12 into a tool holder 10. The device includes a frame 20 and a fixture 31 mounted on the frame 20. The frame 20 is equipped with a first tool holder body acquisition mechanism 40, a second tool holder body acquisition mechanism 50, a riveting mechanism 60, and a finished product handling mechanism 70. The first tool holder body 11 has a through hole 111. A positioning member 322 is provided on the fixture 31, and the positioning member 322 is configured to cooperate with the through hole 111 to position the first tool holder body 11 on the fixture 31. The first tool holder body acquisition mechanism 40 includes a clamping member 41 and a positioning member 42. The clamping member 41 is configured to hold the first tool holder body 11 and move from a first position to a second position along a first direction; the positioning member 42 is movably disposed on the clamping member 41 by means of an elastic member 43, and the positioning member 42 is configured to cooperate with the through hole 111; wherein, at the first position, the positioning member 42 is restricted from further movement in the first direction by the positioning member 322, and the clamping member 41 continues to move along the first direction to the second position by compressing the elastic member 43, so that the positioning member 42 is separated from the through hole 111, and at the same time the positioning member 322 extends into the through hole 111 to place the first tool holder body 11 in the clamp 31.
[0025] During equipment operation, the positioning member 42 extends into the through hole 111 of the first tool holder body 11; the clamping member 41 clamps the first tool holder body 11; the clamping member 41 moves the first tool holder body 11 to the first position, at which point the positioning member 42 is restricted from further movement in the first direction by the positioning member 322; the clamping member 41 continues to move along the first direction to a second position by compressing the elastic member 43, at which point the positioning member 42 separates from the through hole 111, and the positioning member 322 extends into the through hole 111 to place the first tool holder body 11 on the fixture 31, achieving precise positioning and fixation of the first tool holder body 11 on the fixture 31. Subsequently, the clamping member 41 releases the first tool holder body 11 and retracts, completing the placement process of the first tool holder body 11, providing a precise positioning basis for the subsequent assembly and riveting process of the second tool holder body 12.
[0026] The automatic tool holder assembly equipment 100 achieves high-precision and rapid positioning of the first tool holder body 11 on the fixture 31 through the precise fit design between the positioning component 322 and the through hole 111 of the first tool holder body 11, combined with the automatic separation mechanism of the elastic positioning component 42. This effectively solves the assembly defects caused by positioning deviations in the traditional assembly process, and significantly improves the accuracy consistency and production efficiency of the tool holder 10 assembly.
[0027] In this embodiment, as Figure 3 As shown, both the first tool holder body 11 and the second tool holder body 12 are generally plate-shaped structures. During the assembly of the tool holder 10, the second tool holder body 12 is placed above the first tool holder body 11. The first tool holder body 11 has a riveting portion 112, and the second tool holder body 12 has a riveting groove that mates with the riveting portion 112. When the second tool holder body acquiring mechanism 50 places the acquired second tool holder body 12 onto the first tool holder body 11, the riveting portion 112 is located in the riveting groove. Then, the riveting mechanism 60 rivets the riveting portion 112 into the riveting groove to fix the first tool holder body 11 and the second tool holder body 12. The riveting portions are located above the first tool holder body 11, and there are multiple riveting portions 112. The number of riveting grooves corresponds to the number of riveting portions 112, so that the riveting portions 112 extend into the corresponding riveting grooves.
[0028] In this embodiment, as Figures 1 to 3As shown, the frame 20 serves as the support structure for the equipment. The frame 20 supports the fixture 31, the first tool holder acquisition mechanism 40, the second tool holder acquisition mechanism 50, the riveting mechanism 60, and the finished product handling mechanism 70, ensuring the stability and reliability of the entire equipment. The structure of the frame 20 is not strictly limited; it only needs to support the fixture 31, the first tool holder acquisition mechanism 40, the second tool holder acquisition mechanism 50, the riveting mechanism 60, and the finished product handling mechanism 70, etc., and will not be further elaborated here. For example, the frame 20 can be a frame structure.
[0029] In this embodiment, as Figures 2 to 3 As shown, the automatic tool holder assembly equipment 100 also includes a turntable 30 and multiple clamps 31, which are spaced apart circumferentially around the turntable 30. The turntable 30 is configured to rotate about a fixed axis and is mounted on the frame 20; the rotation of the turntable 30 enables assembly line operation and improves assembly efficiency. In operation, the turntable 30 rotates about a vertical axis. The automatic tool holder assembly equipment 100 also includes a motor for driving the turntable 30.

During rotation, the turntable 30 drives the fixture 31, giving the fixture 31 multiple workstations; each workstation corresponds to one of the first tool holder body acquiring mechanism 40, the second tool holder body acquiring mechanism 50, the riveting mechanism 60, or the finished product picking mechanism 70.
[0031] In this embodiment, as Figures 2 to 3 As shown, the fixture 31 is fixed to the turntable 30; the fixture 31 is used to support and position the components in the tool holder 10, ensuring stability and accuracy during the assembly process. The number of fixtures 31 is not strictly required and can be adjusted according to actual needs, which will not be further elaborated here. For example, eight fixtures 31 can be used to improve the working efficiency of the automatic tool holder assembly equipment 100.
[0032] In this embodiment, as Figures 2 to 3 As shown, the fixture 31 includes a fixed base 311 and a plurality of positioning pins 312. The fixed base 311 is fixedly connected to the turntable 30. The plurality of positioning pins 312 are spaced around the outer periphery of the first tool holder body 11 and cooperate with the positioning member 322 to position the first tool holder body 11 on the fixed base 311.
[0033] In this embodiment, as Figures 2 to 3As shown, the shape of the fixing seat 311 is not strictly limited; for example, the shape of the fixing seat 311 is roughly a block structure; the fixing seat 311 can be fixed to the turntable 30 by welding or bolts.
[0034] In this embodiment, as Figures 2 to 3 As shown, both the positioning element 322 and the positioning post 312 are rod-shaped structures; the fixing base 311 has multiple fixing holes, and the positioning element 322 and the positioning post 312 extend into the corresponding fixing holes and are fixed to the fixing base 311 by welding or bolts. Both the positioning element 322 and the positioning post 312 protrude outward from the top of the fixing base 311, so that the positioning element 322 can extend into the through hole 111 on the first tool holder body 11, and the positioning post 312 is located on one side of the first tool holder body 11.
[0035] In this embodiment, as Figures 2 to 3 As shown, the length of the positioning member 322 is greater than the length of the through hole 111. When the first tool holder body 11 is placed on the clamp 31, the top of the positioning member 322 is higher than the first tool holder body 11, so that the positioning member 42 can be completely separated from the through hole 111. To facilitate the guidance of the positioning member 322 into the through hole 111, the positioning member 322 is provided with a guide portion 3221, which is configured to guide the positioning member 322 into the through hole 111. The guide portion 3221 is located at the top of the positioning member 322; the cross-section of the guide portion 3221 decreases from the end connected to the positioning member 322 to the end away from the positioning member 322, so as to facilitate the guide portion 3221 into the through hole 111.
[0036] In this embodiment, as Figure 2 as well as Figure 4 As shown, the first tool holder body acquisition mechanism 40 further includes a first tool holder body conveying line 45 for conveying the first tool holder body 11; the positioning member 42 extends into the through hole 111 of the first tool holder body 11 located on the first tool holder body conveying line 45, and clamps the first tool holder body 11 by the clamping member 41. The first tool holder body acquisition mechanism 40 also includes a first tool holder body vibratory feeder 44, which conveys the first tool holder body 11 to the first tool holder body conveying line 45 to organize the scattered first tool holder bodies 11 into an orderly state for subsequent operations. The first tool holder body conveying line 45 and the first tool holder body vibratory feeder 44 can both employ existing technologies, and will not be further elaborated here.
[0037] In this embodiment, as Figure 2 as well as Figure 4As shown, the first tool holder body conveying line 45 includes a first tool holder body conveying line 451 and a first tool holder body transfer line 452. One end of the first tool holder body conveying line 451 is connected to the first tool holder body vibrating plate 44 so that the first tool holder body 11 output from the first tool holder body vibrating plate 44 enters the first tool holder body conveying line 451. The first tool holder body transfer line 452 is connected to the first tool holder body conveying line 451 so that the first tool holder body 11 in the first tool holder body conveying line 451 enters the first tool holder body transfer line 452. The positioning member 42 extends into the through hole 111 of the first tool holder body 11 located on the first tool holder body transfer line 452, and clamps the first tool holder body 11 by the clamping member 41.
[0038] In this embodiment, as Figure 2 as well as Figure 4 As shown, the first tool holder body transfer line 452 includes a first tool holder body fixing seat 4521, a first tool holder body transfer seat 4522, and a first tool holder body driving member 4523; the first tool holder body transfer seat 4522 is used to receive the first tool holder body 11 transported by the first tool holder body transport line 451; the first tool holder body transfer seat 4522 is movably configured on the first tool holder body fixing seat 4521; the first tool holder body driving member 4523 drives the first tool holder body transfer seat 4522 to move from the third position to the fourth position. At the third position, the first tool holder body conveyor line 451 conveys the first tool holder body 11 to the first tool holder body transfer seat 4522. The first tool holder body drive member 4523 drives the first tool holder body transfer seat 4522 to move from the third position to the fourth position. At the fourth position, the positioning member 42 extends into the through hole 111 of the first tool holder body 11 located on the first tool holder body transfer line 452, and clamps the first tool holder body 11 by the clamping member 41.
[0039] In this embodiment, as Figure 2 as well as Figure 4 As shown, the first tool holder body conveyor line 451 is fixed to the frame 20 by bolts or welding. The first tool holder body conveyor line 451 has a first tool holder body conveying channel connected to the first tool holder body vibratory feeder 44; the first tool holder body 11 output from the first tool holder body vibratory feeder 44 is conveyed to the first tool holder body conveying channel. The first tool holder body fixing seat 4521 is fixed to the frame 20 by bolts or welding. The first tool holder body transfer seat 4522 is located above the first tool holder body fixing seat 4521 and has a first tool holder body placement area for placing the first tool holder body 11; at the third position, the first tool holder body placement area corresponds to the first tool holder body conveying channel. The first tool holder body driving component 4523 is a cylinder or push rod motor.
[0040] In this embodiment, as Figure 2 as well as Figure 4As shown, at the fourth position, the first tool holder placement area and the first tool holder conveying channel are offset to prevent the first tool holder 11 in the first tool holder conveying channel from affecting the gripping of the first tool holder 11 in the first tool holder placement area. The first tool holder placement area has first tool holder clearance areas on both sides to facilitate the gripping member 41 to grip both sides of the first tool holder 11.
[0041] In this embodiment, as Figures 2 to 8 As shown, the clamping member 41 includes a movable seat 411 and a gripper 412 disposed on the movable seat 411; the movable seat 411 drives the gripper 412 to move, thereby moving the gripper 412 to the first tool holder body transfer seat 4522, the first position, and the second position. Existing technology can be used to drive the movable seat 411 to move; for example, the clamping member 41 includes a first guide rail 413, a movable seat 414, a second guide rail 415, a first cylinder, and a second cylinder; the first guide rail 413 is horizontally arranged, and the movable seat 414 is movably attached to the first guide rail 413; the first cylinder drives the movable seat 414 to move along the first guide rail 413; the second guide rail 415 is vertically arranged and movably attached to the movable seat 414; the second cylinder drives the second guide rail 415 to move in the vertical direction; the movable seat 411 is fixed to the bottom of the second guide rail 415. When the first cylinder drives the movable seat 414 to move along the first guide rail 413, it drives the movable seat 411 and the gripper 412 to move horizontally via the second guide rail 415; when the second cylinder drives the second guide rail 415 to move vertically, it drives the movable seat 411 and the gripper 412 to move vertically. The gripper 412 can be a pneumatic gripper.
[0042] In this embodiment, as Figures 2 to 8 As shown, the positioning member 42 is generally rod-shaped. To facilitate the insertion of the positioning member 42 into the through hole 111, the positioning member 42 is provided with a guide portion 3221, which is configured to guide the positioning member 42 into the through hole 111. The guide portion 3221 is located at the top of the positioning member 42; the cross-section of the guide portion 3221 decreases from the end connected to the positioning member 42 to the end away from the positioning member 42, so as to facilitate the insertion of the guide portion 3221 into the through hole 111.
[0043] In this embodiment, as Figures 2 to 8As shown, one of the positioning member 322 and the positioning component 42 is provided with a positioning protrusion 3222, and the other is provided with a positioning groove 421; at the first position, the positioning protrusion 3222 is located within the positioning groove 421. The positioning protrusion 3222 and the positioning groove ensure that the first tool holder 11 maintains a stable posture during the transfer process, avoiding positioning errors caused by vibration or offset, and allowing the positioning member 322 to smoothly extend into the through hole 111 of the first tool holder 11 for precise placement, significantly improving the repeatability of positioning during the assembly process and the stability of equipment operation. The cross-sectional area of the positioning groove decreases from the opening to the bottom wall. The positioning protrusion 3222 is at least a part of the guide portion 3221.
[0044] In this embodiment, as Figures 2 to 8 As shown, the positioning member 42 is movably disposed on the movable seat 411 by means of the elastic member 43. The first tool holder body acquisition mechanism 40 further includes a connecting part 46 and a fixing part 47; the connecting part 46 is fixedly connected to the movable seat 411 and has a sliding hole that mates with the positioning member 42; the fixing part 47 is fixedly connected to the positioning member 42, and the elastic member 43 is disposed between the connecting part 46 and the fixing part 47.
[0045] In this embodiment, as Figures 2 to 8 As shown, there are two connecting portions 46, which are spaced apart along the moving direction of the positioning member 42; the fixing portion 47 is located between the two connecting portions 46. Of the two connecting portions 46, the connecting portion 46 closer to the clamp 31 is the first connecting portion 461, and the connecting portion 46 farther from the clamp 31 is the second connecting portion 462; the first connecting portion 461 is located below the second connecting portion 462; the elastic member 43 presses against the fixing portion 47 and the second connecting portion 462. The elastic member 43 is a spring.
[0046] In this embodiment, as Figure 2 and Figure 9 As shown, the second tool holder body acquisition mechanism 50 includes a second tool holder body vibratory feeder 51, a second tool holder body conveying line 52, and a second tool holder body gripper 53. The second tool holder body vibratory feeder 51 conveys the second tool holder body 12 to the second tool holder body conveying line 52 to organize the scattered second tool holder bodies 12 into an orderly state for easy subsequent operations. The second tool holder body conveying line 52 is used to transport the second tool holder body 12. The second tool holder body gripper 53 grasps the second tool holder body 12 conveyed by the second tool holder body conveying line 52 and places the grasped second tool holder body 12 on the first tool holder body 11. The second tool holder body vibratory feeder 51, the second tool holder body conveying line 52, and the second tool holder body gripper 53 can all adopt existing technologies, and will not be further described here.
[0047] In this embodiment, as Figure 2 , Figure 10 and Figure 11 As shown, the riveting mechanism 60 includes a punch 61 and a support member 62. The punch 61 is configured to punch the riveting part 112 to rivet the riveting part 112 into the riveting groove. The support member 62 is configured to support the fixture 31 when the punch 61 punches the riveting part 112. When the second tool holder 12 is placed on the first tool holder 11, the punch 61 moves downward and applies an impact force to the riveting part 112 of the first tool holder 11, causing the material of the riveting part 112 to undergo plastic deformation so that it is riveted into the riveting groove to form a mechanical connection. At this time, the support member 62 simultaneously presses against the bottom of the fixture 31, effectively absorbing the punching impact force and preventing the fixture 31 from shifting or vibrating during the riveting process.
[0048] In this embodiment, as Figure 10 and Figure 11 As shown, the riveting mechanism 60 includes multiple punches 61; the number of punches 61 corresponds one-to-one with the number of riveting portions 112 of the first tool holder body 11, ensuring that each riveting portion 112 receives synchronous punching force. The riveting mechanism 60 also includes a first riveting drive member 64, which provides controllable impact kinetic energy to the punches 61, driving the punches 61 to descend at high speed and precisely punch the riveting portions 112. The first riveting drive member 64 utilizes existing technology; it only needs to be able to drive the punches 61. For example, the first riveting drive member 64 can be a cylinder.
[0049] In this embodiment, as Figure 10 and Figure 11 As shown, the riveting mechanism 60 for the support member 62 also includes a second riveting drive member 63. When riveting the tool holder 10 on the fixture 31, the second riveting drive member 63 drives the support member 62 to press upward against the bottom of the fixture 31. After the tool holder 10 on the fixture 31 is riveted, the second riveting drive member 63 reverses its action, driving the support member 62 to move downward, making room for the fixture 31 to be smoothly transferred to the next work position. The second riveting drive member 63 can be any existing technology, as long as it can drive the support member 62; for example, the second riveting drive member 63 can be a cylinder, etc.
[0050] In this embodiment, as Figure 2 and Figure 12As shown, the finished product handling mechanism 70 includes a handling gripper 71 and a dispensing box 72. After the tool holder 10 assembly process is completed, the handling gripper 71 moves above the fixture 31 to grasp the riveted finished tool holder 10, then transfers it to the dispensing box 72. Finally, the handling gripper 71 opens to place the tool holder 10 into the dispensing box 72, thus achieving automatic finished product collection and buffering. The movement and gripping of the handling gripper 71 can utilize existing technology and will not be further elaborated here.
[0051] like Figures 1 to 12 As shown, this application also provides an assembly method for an automatic tool holder assembly device based on the above embodiments, including the following steps: S100, The positioning component extends into the through hole of the first tool holder body. The first tool holder body vibratory plate organizes the scattered first tool holder bodies into an orderly state, and then conveys them to the first tool holder body transfer seat via the first tool holder body conveyor line; the positioning component extends into the through hole of the tool holder body on the conveyor line.
[0052] S200, The clamping member clamps the first tool holder body.
[0053] S300, the clamping member moves the first tool holder body to the first position, at which time the positioning member is restricted from further movement in the first direction by the positioning element. When the positioning member is restricted from further movement in the first direction by the positioning element, the positioning protrusion of the positioning member engages with the positioning groove of the clamp positioning element.
[0054] S400, the clamping member continues to move to a second position along the first direction by compressing the elastic member. At this time, the positioning member separates from the through hole, and the positioning member extends into the through hole to place the first tool holder body in the clamp.
[0055] S500, the turntable rotates and drives the fixture to the next station. The second tool holder body, conveyed by the second tool holder body vibratory plate, is transported by the second tool holder body conveyor line. The second tool holder body gripper grabs the second tool holder body and stacks it on the first tool holder body, so that the multiple riveting parts of the first tool holder body are inserted into the riveting grooves of the second tool holder body, forming a pre-assembly state.
[0056] S600, the turntable drives the fixture to rotate to the next station, the second riveting drive pushes the support component to the bottom of the fixture; the first riveting drive drives multiple punches to move down synchronously, applying a controllable impact force to the riveting part, causing the material of the riveting part to plastically deform and be riveted to the riveting groove.
[0057] After the S700 riveting is completed, the turntable drives the fixture to rotate to the next station, the pick-up claw grabs the finished tool holder and transfers it to the material box.
[0058] The technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered to be within the scope of this specification. When technical features of different embodiments are embodied in the same drawing, it can be regarded as the drawing also disclosing examples of combinations of the various embodiments involved.
[0059] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
