Description

Technical Field

[0001] This invention relates to the field of screw-locking equipment technology, and in particular to a multifunctional long screw flexible clamping anti-sway positioning assembly mechanism. Background Technology

[0002] The screw-locking device used in the factory is an electric tightening device on the production line that replaces manual labor. The feeder sorts and blows or sucks the screws into the screwdriver bit. The robotic arm or lifting module presses down with the electric screwdriver bit, and after the bit bites the screw head, it rotates and drives into the threaded hole of the workpiece. Its core functions are automatic feeding, automatic alignment, and automatic tightening, which improves the assembly cycle and consistency and reduces labor costs.

[0003] Existing technology provides an automatic screw-locking device compatible with multiple screw sizes, publication number CN121552066B. This invention includes a main support and a screw-locking mounting bracket fixedly mounted on the main support. A lifting platform is slidably connected to the surface of the screw-locking mounting bracket. Four evenly distributed compensating rods are arranged below the lifting platform. Each compensating rod contains a tool changer. Each tool changer contains three rotating shafts, which are grouped together. Each group of three rotating shafts has a corresponding screwdriver clamped below it. Through the design of three sets of different specifications of screwdriver heads in the tool changer, it can quickly switch to adapt to the tightening requirements of different screw sizes. The screwdriver head size can also be flexibly changed according to the processing environment. At the same time, it can effectively reduce manual labor. However, the existing technology still has the following problems:

[0004] Screws with a large length-to-diameter ratio lack restraint at the tail when driven from one end. During rotation, centrifugal force can easily cause the screw to swing, making it impossible to accurately guide the screw into the threaded hole. Forcing it in will inevitably result in skewed threads, stripped threads, and damage to the workpiece. At the same time, traditional clamping structures either block the screw head from reaching the bottom or press a pit into the workpiece surface when the screw head needs to be fully depressed. The screw must be inserted axially from the front end of the chuck, which is awkward to operate and slow for batch operations. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0006] In view of the problems existing in the above and / or existing multifunctional long screw flexible clamping anti-sway positioning assembly mechanisms, the present invention is proposed.

[0007] Therefore, the problem to be solved by this invention is how to ensure that both ends of a long screw are positioned, the middle is prevented from swaying, and the end clamping block can be positioned throughout the entire process from loading to tightening.

[0008] To solve the above technical problems, the present invention provides the following technical solution: a multifunctional long screw flexible clamping anti-sway positioning assembly mechanism, including a long screw positioning transmission component and a drive motor that provides power to the long screw positioning transmission component, wherein the drive motor is plugged into and installed with the long screw positioning transmission component; The long screw positioning transmission assembly includes a sleeve, a positioning mechanism, and a flexible clamping mechanism. A transmission rod and a sleeve are slidably connected inside the sleeve. The top end of the transmission rod is inserted into the output shaft of a drive motor, and the bottom end of the transmission rod is provided with a connector. The connector is used to limit the top end of the long screw and provide torque. The bottom of the positioning mechanism is rotatably connected to the flexible clamping mechanism. The flexible clamping mechanism is used to position the bottom end of the long screw. The positioning mechanism is slidably connected to the inside of the sleeve and resets under the elastic force of a spring.

[0009] Preferably, the positioning mechanism includes a mounting sleeve and two telescopic brackets. A slider is fixed on the top surface of the two telescopic brackets. A limiting groove is correspondingly opened on the bottom surface of the mounting sleeve. The slider is slidably connected in the limiting groove. The tops of the two telescopic brackets are slidably connected through a reset member. The bottom end of the sleeve is set as a cone. Guide wheels are respectively installed on the inner side of the top of the two telescopic brackets. With the telescopic bracket extended from the sleeve, the cone acts on the guide wheel, causing the two telescopic brackets to move in opposite directions on the mounting sleeve via the slider.

[0010] Preferably, the reset component includes an L-shaped plate and a spring. The two telescopic brackets have notches on opposite sides and on both sides. The L-shaped plates are fixed in the notches and are mirror-flipped. Symmetrical fixing posts are fixed to the side walls of the two L-shaped plates, and the two ends of the spring are sleeved on the fixing posts.

[0011] Preferably, the bottom side wall of the telescopic bracket has a rotating groove, and the flexible clamping mechanism is rotatably installed in the rotating groove. The flexible clamping mechanism includes a movable clamping block and a shaft pin. The movable clamping block is rotatably connected in the rotating groove through the shaft pin, and a torsion spring is sleeved on the side wall of the shaft pin. A limit rod is fixedly installed on the telescopic bracket located below the movable clamping block. The end of the movable clamping block located inside the telescopic bracket has a long screw through hole for the bottom end of a long screw to pass through. The bottom sides of the sleeve have clearance grooves for the outer end of the movable clamping block to move.

[0012] Preferably, a negative pressure mechanism is fixedly installed on the top of the sleeve. The negative pressure mechanism includes an air guide slip ring, and an air nozzle is provided on the side wall of the air guide slip ring. A negative pressure air groove is opened inside the transmission rod. The negative pressure air groove is connected to the air nozzle through the air guide slip ring. A hexagonal groove for installing the head of a long screw is opened on the bottom surface of the connector. The negative pressure air groove is located on the bottom surface of the hexagonal groove.

[0013] Preferably, the top sidewall of the sleeve has a threaded groove, and an adjusting ring is threaded onto the threaded groove. The end of the second spring abuts against the adjusting ring. The second spring is located in the gap between the sleeve and the bushing. The top sidewall of the bushing has an adjusting groove for adjusting the position of the adjusting ring.

[0014] Preferably, the long screw positioning transmission assembly and the first drive motor are both fixedly installed via a movable frame. A vertical moving assembly is installed on the side wall of the movable frame. The vertical moving assembly includes a second drive motor and a support frame. The top of the support frame is fixedly installed to the second drive motor via a motor frame. A lead screw is installed on the output shaft of the second drive motor. A nut seat is threadedly connected to the side wall of the lead screw. A movable seat is installed on the side wall of the nut seat. The movable frame is fixedly installed to the side wall of the movable seat.

[0015] Preferably, a mounting bracket is fixedly installed on the side wall of the support frame, a main shaft is inserted and fixedly connected to the side wall of the mounting bracket, a lateral movement component is slidably connected to the side wall of the main shaft, and a reversing component is fixedly installed at the tail of the main shaft.

[0016] Preferably, the lateral movement component includes a vertical plate, a linear module, and a cylinder. The bottom of the vertical plate is slidably connected to the base via the linear module. The base has a second sliding groove, and the side wall of the vertical plate has a first sliding groove. The main shaft is slidably connected in the first sliding groove under the reversing motion of the reversing component. A fixing plate is fixedly connected to the bottom surface of the vertical plate. The cylinder is fixedly installed on the bottom surface of the base, and the telescopic shaft of the cylinder is fixedly installed to the side wall of the fixing plate.

[0017] Preferably, the reversing assembly includes a guide plate, the side wall of which is provided with a guide groove in the shape of an "L" and two pulleys are slidably connected in the guide groove. The two pulleys are respectively fixedly installed on one end of a rotating plate, and the main shaft is fixedly installed on the other side of the rotating plate.

[0018] The beneficial effects of this invention are: 1. The connector at the end of the transmission rod applies torque and axial support to the head of the long screw. At the same time, the movable clamping block, which is rotatably mounted at the bottom of the telescopic bracket, forms a radial clamping on the bottom of the long screw. Throughout the entire process from the screw tip contacting the workpiece to the screw head being fully screwed in, both ends are constrained, and the screw cannot swing laterally. When the screw is screwed to the end, the connector first abuts against the top surface of the two movable clamping blocks, causing them to rotate outward around the pivot pin. The clearance groove provides space for the clamping blocks to fold outward. The clamping blocks actively make way, without hindering the connector from continuing to advance, ensuring that the screw head is in place without impacting the workpiece surface. This solves the problem that long screws are prone to swinging, cannot be accurately inserted into the threaded hole, and will inevitably cause skewed threads, stripping, and damage to the workpiece if forced in.

[0019] 2. In the positioning mechanism, the tops of the two telescopic brackets are radially slidably connected to the mounting sleeve via sliders, and the centripetal restoring force is provided by spring one in the reset component. The cone at the bottom of the sleeve and the guide wheel on the inner side of the top of the telescopic bracket form an interference position, so that when spring two pushes the telescopic bracket out of the sleeve and it is not in working state, the cone is forcibly inserted between the two guide wheels, and the two telescopic brackets are opened by the cone surface, which drives the movable clamp at the bottom to separate in opposite directions. The long screw hole is opened to the side, and the operator can directly put the long screw in from the side without having to insert it axially from the front end of the clamp.

[0020] Meanwhile, in conjunction with the vertical moving component, the horizontal moving component, and the reversing component, it is easy to assist the screw feeding device in directly loading long screws from the side, or to quickly load them manually. After loading is completed, the reversing component and the horizontal moving component reverse their movements, and the device returns to the vertical screw-driving posture, simplifying the loading operation and adapting to rapid batch operations and automated feeding docking.

[0033] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0034] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0035] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0036] Example 1, referring to Figures 1-5 This is the first embodiment of the present invention. This embodiment provides a multifunctional long screw flexible clamping anti-sway positioning assembly mechanism, including a long screw positioning transmission component 1 and a drive motor 2 that provides power to the long screw positioning transmission component 1. The drive motor 2 is plugged into and installed with the long screw positioning transmission component 1. The long screw positioning transmission component 1 provides the installation position for the long screw and can maintain the perpendicularity of the long screw when driving the long screw into the product, preventing the long screw from shifting or shaking during the process of screwing it into the threaded hole of the equipment.

[0037] The long screw positioning transmission assembly 1 includes a sleeve 11, a positioning mechanism 12, and a flexible clamping mechanism 13. A transmission rod 15 and a sleeve 16 are slidably connected inside the sleeve 11. The top end of the transmission rod 15 is inserted and installed into the output shaft of the drive motor 2. The bottom end of the transmission rod 15 is provided with a connector 151, which is used to limit the top end of the long screw and provide torque. The bottom of the positioning mechanism 12 is rotatably connected to the flexible clamping mechanism 13. The flexible clamping mechanism 13 is used to position the bottom end of the long screw. The positioning mechanism 12 is slidably connected to the inside of the sleeve 11 and resets under the elastic force of the spring 17.

[0038] The working principle is as follows: The output shaft of the drive motor 12 is inserted into the top of the transmission rod 15. The torque is transmitted to the head of the long screw through the transmission rod 15 and the connector 151. When not pressed down, the spring 2 17 pushes the positioning mechanism 12 together with the flexible clamping mechanism 13 towards the lower end of the sleeve 11. The bottom end of the long screw is radially limited by the long screw through hole 132 on the movable clamping block 131, and the top end is circumferentially driven by the connector 151. When pressed down, the sleeve 11 moves relative to the downward workpiece, the spring 2 17 is compressed, and the movable clamping block 131 always clamps the bottom end of the screw to keep it vertical until the screw is driven into the threaded hole of the product. When the sleeve 11 is not pressed down, it is reset under the elastic force of the spring 2 17, preparing for the next long screw to be screwed in.

[0039] The positioning mechanism 12 includes a mounting sleeve 121 and two telescopic brackets 122. Two telescopic brackets 122 are mounted on the bottom of the mounting sleeve 121. A rotating groove 125 is formed on the bottom side wall of each telescopic bracket 122. A flexible clamping mechanism 13 is rotatably mounted in the rotating groove 125. The flexible clamping mechanism 13 includes a movable clamping block 131 and a pin 135. The movable clamping block 131 is rotatably connected in the rotating groove 125 via the pin 135. A torsion spring 133 is sleeved on the side wall of the pin 135, with one end abutting against the telescopic bracket 122. 22, one end abuts against the movable clamping block 131 to provide torque, and a limit rod 134 is fixedly installed on the telescopic bracket 122 located below the movable clamping block 131, so that the free ends of the two movable clamping blocks 131 approach each other until they are blocked by the limit rod 134 and cannot continue to rotate inward. The end of the movable clamping block 131 located inside the telescopic bracket 122 is provided with a long screw through hole 132 for the bottom end of the long screw to pass through, and the bottom sides of the sleeve 11 are provided with relief grooves 112 for the outer end of the movable clamping block 131 to move.

[0040] When the long screw is driven to the end, the connector 151 needs to pass over the movable clamp 131 to allow the slot 112 to provide space for the movable clamp 131 to enter the sleeve 11. The connector 151 first abuts against the top surface of the two movable clamps 131. As the movable clamps 131 rotate along the axis, the connector 151 is placed between the two inclined movable clamps 131, thereby driving the long screw completely into the product.

[0041] During this process, the two movable clamping blocks 131 continuously position the bottom of the long screw, so that from the moment the long screw is screwed into the threaded hole of the product until it is fully screwed in, both ends of the long screw are always positioned and in a vertical state, thus ensuring the stability of the long screw and preventing it from shaking or tilting.

[0042] Furthermore, a threaded groove 172 is provided on the top side wall of the sleeve 16, and an adjusting ring 171 is threadedly connected to the threaded groove 172. The end of the second spring 17 abuts against the adjusting ring 171. The second spring 17 is located in the gap between the sleeve 16 and the sleeve 11. An adjusting groove 111 is provided on the top side wall of the sleeve 11 for adjusting the position of the adjusting ring 171. One end of the second spring 17 abuts against the adjusting ring 171, and the other end abuts against the inner step or end face of the sleeve 11. The compression of the second spring 17 is changed by rotating the adjusting ring 171 to change its axial position. The adjustment of the adjusting ring 171 can be adjusted by adjusting the adjusting groove 111 with the help of a tool. When the adjusting ring 171 moves toward the connector 151, the pre-compression of the second spring 17 increases, and vice versa. Thus, a suitable pre-pressure can be preset for screws of different lengths and different self-tapping resistances.

[0043] Furthermore, a rubber pad 18 is fixed to the bottom surface of the telescopic bracket 122 by screws. The rubber pad 18 reduces friction with the surface of the workpiece or product, so as to ensure that the surface of the workpiece or product is not easily damaged during the tightening of the screw.

[0044] Example 2, refer to Figures 4-8 This is the second embodiment of the present invention, which is based on the previous embodiment. The positioning mechanism 12 includes a mounting sleeve 121 and two telescopic brackets 122. The upper ends of the two telescopic brackets 122 are changed to be slidably connected. A slider 123 is fixed on the top surface of the two telescopic brackets 122. A limit groove is correspondingly opened on the bottom surface of the mounting sleeve 121. The slider 123 is slidably connected in the limit groove. The tops of the two telescopic brackets 122 are slidably connected through a reset member 124. The bottom end of the sleeve 16 is set as a cone head 161. Guide wheels 126 are respectively installed on the inner side of the top of the two telescopic brackets 122. When the telescopic brackets 122 are extended from the sleeve 16, the cone head 161 acts on the guide wheel 126, so that the two telescopic brackets 122 move in opposite directions on the mounting sleeve 121 through the slider 123.

[0045] When the cone 161 is not in operation, under the elastic force of the second spring 17, as the telescopic bracket 122 fully extends from the sleeve 11, the cone 161 inserts between the inner tops of the two telescopic brackets 122, and the cone surface presses against the guide wheel 126, forcibly pushing the two telescopic brackets 122 outward. At this time, the two movable clamping blocks 131 move away from the telescopic brackets 122, and the long screw hole 132 opens, forming a laterally open filling space. When the screw is pressed down, the cone 161 moves upward and disengages from the guide wheel 126, and the telescopic bracket 122 enters the sleeve 11. Under the spring push of the reset member 124, the telescopic bracket 122 resets and closes, and the movable clamping block 131 closes again, clamping the bottom end of the screw.

[0046] Specifically, the reset component 124 includes an L-shaped plate 1242 and a spring 1244. The two telescopic brackets 122 have notches 1241 on opposite sides. The L-shaped plates 1242 are fixed in the notches 1241 and are mirror images of each other. Symmetrical fixing posts 1243 are fixed on the side walls of the two L-shaped plates 1242, and the two ends of the spring 1244 are sleeved on the fixing posts 1243.

[0047] When the conical surface presses on the guide wheel 126, it forces the two telescopic brackets 122 to open outward, and the spring 1244 is compressed. When the screw is pressed down, the conical head 161 moves up and disengages from the guide wheel 126. The spring 1244 rebounds and pushes the two L-shaped plates 1242 away, so that the telescopic brackets 122 reset and close, and the movable clamping block 131 closes again to clamp the bottom end of the screw.

[0048] Furthermore, such as Figure 2As shown, the long screw positioning transmission assembly 1 and the drive motor 2 are both fixedly installed via the movable frame 3. The side wall of the movable frame 3 is equipped with a vertical moving assembly 4, which includes a drive motor 41 and a support frame 43. The top of the support frame 43 is fixedly installed with the drive motor 41 via a motor frame 42. The output shaft of the drive motor 41 is equipped with a lead screw 44. The side wall of the lead screw 44 is threadedly connected to a nut seat 45. The side wall of the nut seat 45 is equipped with a movable seat 46. The movable frame 3 is fixedly installed with the side wall of the movable seat 46.

[0049] The second drive motor 41 is mounted on the top of the support frame 43 via the motor frame 42. Its output shaft drives the lead screw 44 to rotate. The lead screw 44 drives the nut seat 45 and the movable seat 46 fixed thereto to move along the axial direction of the lead screw 44. The movable frame 3 is fixed to the side wall of the movable seat 46. Therefore, the second drive motor 41 can drive the entire screw-driving device to rise and fall vertically by reversing forward and reverse. The downward screw-driving action is controlled by the feed of the second drive motor 41, rather than by manual pressure, which solves the problems of screw floating, stripping, or workpiece damage caused by uncontrollable manual downward pressure.

[0050] As an optimized solution of this embodiment: a negative pressure mechanism 14 is fixedly installed on the top of the sleeve 11. The negative pressure mechanism 14 includes an air guide slip ring 141. An air nozzle 142 is provided on the side wall of the air guide slip ring 141. A negative pressure air groove 153 is opened inside the transmission rod 15. The negative pressure air groove 153 is connected to the air nozzle 142 through the air guide slip ring 141. A hexagonal groove 152 for installing the head of a long screw is opened on the bottom surface of the connector 151. The negative pressure air groove 153 is located on the bottom surface of the hexagonal groove 152.

[0051] The air nozzle 142 is connected to an external negative pressure source. The negative pressure is introduced into the negative pressure air groove 153 inside the transmission rod 15 through the air guide slip ring 141. The air groove 153 is directly connected to the hexagonal groove 152 on the bottom surface of the connector 151. When the head of the long screw is inserted into the hexagonal groove 152, the negative pressure attracts the screw head to the bottom of the groove, and the screw is axially held in place. When the transmission rod 15 rotates, the outer ring of the air guide slip ring 141 is relatively stationary, while the inner ring rotates with the transmission rod 15, keeping the air passage connected and preventing entanglement. When the screw is driven to the bottom and disengages from the connector 151, the hexagonal groove 152 opens, the negative pressure disappears, and the screw is automatically separated. This solves the problem that long screws are easy to fall off the connector 151 after initial loading, improving the reliability of feeding and the continuity of operation.

[0052] Example 3, referring to Figures 9-10 This is the third embodiment of the present invention. This embodiment is based on the first two embodiments. The function of this embodiment is to enable the long screw positioning transmission assembly 1 to rotate 90° when screwing is not required, so that the vertical long screw positioning transmission assembly 1 can be set horizontally, so that the long screw can be provided to the long screw positioning transmission assembly 1 by the auxiliary screw feeding device, and at the same time, it can also facilitate the filling of long screws.

[0053] A mounting bracket 5 is fixedly installed on the side wall of the support frame 43. A main shaft 6 is inserted and fixed on the side wall of the mounting bracket 5. A transverse movement component 7 is slidably connected to the side wall of the main shaft 6. A reversing component 8 is fixedly installed at the tail of the main shaft 6.

[0054] Specifically, the lateral movement component 7 includes a vertical plate 71, a linear module 73, and a cylinder 75. The bottom of the vertical plate 71 is slidably connected to the base 9 via the linear module 73. The base 9 has a second sliding groove 91, and the side wall of the vertical plate 71 has a first sliding groove 72. The main shaft 6 is slidably connected in the first sliding groove 72 under the reversing movement of the reversing component 8. A fixing plate 74 is fixedly connected to the bottom surface of the vertical plate 71. The cylinder 75 is fixedly installed on the bottom surface of the base 9, and the telescopic shaft of the cylinder 75 is fixedly installed on the side wall of the fixing plate 74.

[0055] Working principle: The bottom of the vertical plate 71 slides horizontally on the slide groove 91 of the base 9 via the linear module 73. The cylinder 75 extends and retracts to drive the vertical plate 71 to move laterally along the slide groove 91. A vertical slide groove 72 is opened on the side wall of the vertical plate 71. The end of the main shaft 6 can slide in the slide groove 72. When the vertical plate 71 moves laterally, the slide groove 72 generates a horizontal thrust or pull on the main shaft 6. The main shaft 6 moves along its own axis. At the same time, the reversing component 8 applies a rotational constraint to the main shaft 6 through the guide groove 82. The two motions are coupled to complete the reversing and displacement.

[0056] Specifically, the reversing assembly 8 includes a guide plate 81, and a guide groove 82 is provided on the side wall of the guide plate 81. The guide groove 82 is "L" shaped, and two pulleys 83 are slidably connected in the guide groove 82. The two pulleys 83 are respectively fixedly installed on one end of the rotating plate 84, and the main shaft 6 is fixedly installed on the other side of the rotating plate 84.

[0057] When the lateral movement component 7 pushes the main shaft 6 to move, the main shaft 6 drives the rotating plate 84 to translate. The two pulleys 83 first move linearly within the vertical section of the guide groove 82, keeping the device vertical. When they reach the L-shaped corner, with continued pushing, the pulleys 83 are forced to turn along the horizontal section of the guide groove 82, driving the rotating plate 84 to rotate 90°. The main shaft 6, along with the entire screw-driving device, synchronously rotates to the horizontal. Upon resetting, the cylinder 75 reverses its action, and the pulleys 83 return to the vertical section along their original path, restoring the device to verticality. This facilitates the auxiliary screw-feeding device to directly fill long screws from the side, or to quickly fill them manually. After filling, the reversing component 8 and the lateral movement component 7 reverse their actions, and the device returns to the vertical screw-driving posture.
