Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of machining tools, in particular to an assembly device for manufacturing flat jaw pliers. BACKGROUND

[0002] Flat jaw pliers are basic clamps used for fixing and clamping workpieces in machine tool processing, belonging to the category of production tools, and are mainly used for planar, groove and angle processing of equipment such as planers, milling machines, drilling machines, grinding machines and slotting machines. The tool is composed of a plier base, a movable plier block, a plier mouth guard plate, a screw rod and other components. In the manufacturing process of flat jaw pliers, separate parts need to be assembled together, and the plier mouth guard plate needs to be fixed on the plier mouth of the plier base through bolts.

[0003] However, in the prior art, when installing the plier mouth guard plate, the guard plate needs to be aligned at the plier mouth through the bolt hole first, then the bolt is inserted into the hole and tightened, and the guard plate needs to be positioned with reference to the plier base, and the bolt needs to be positioned according to the bolt hole. The assembly of the guard plate and the bolt needs to be completed through two feeding and positioning processes, which increases the complexity of the assembly process. SUMMARY

[0004] The purpose of the present application is to solve the shortcomings in the prior art and provide an assembly device for manufacturing flat jaw pliers. The feeding mechanism is provided, so that when the intercepting plate drives the floating frame to move below the storage groove, the lowermost guard plate in the storage groove falls onto the receiving frame. When the floating frame drives the guard plate to approach the plier base on the transfer frame and passes below the storage cylinder, the guard plate pushes the intercepting rod to deflect upward, so that the bottom end outlet of the storage cylinder is opened. When the mounting hole on the guard plate is aligned with the bottom end outlet of the storage cylinder, the lowermost bolt in the storage cylinder slides into the mounting hole on the guard plate, thereby achieving the effect of one-time feeding of the guard plate and the bolt.

[0007] Preferably, a linear motor is installed on the outer wall of the base, the intercepting plate is fixed to the output end outer wall of the linear motor, and the linear motor drives the intercepting plate to move between the transfer frame and the storage groove.

[0008] Preferably, a pair of symmetrically distributed guide grooves are formed in the outer wall of the intercepting plate, a stroke groove is formed in the outer wall of the floating frame in the horizontal direction, and a slide column slidingly inserted into the guide groove and the stroke groove is arranged on the outer wall of each receiving frame.

[0009] Preferably, a limiting rod vertically upward is arranged on the bottom outer wall of the intercepting plate, the floating frame is slidingly sleeved on the outer wall of the limiting rod, and a first spring sleeved on the outer wall of the limiting rod is arranged between the outer wall of the floating frame and the outer wall of the intercepting plate.

[0010] Preferably, the auxiliary mechanism includes a mounting slot inside the floating frame, a pressure sensor is fixed on the inner wall of the mounting slot, a triangular magnetic block capable of adsorbing the protective plate is slidably inserted into the inner wall of the mounting slot near the transfer frame, the tip of the triangular magnetic block extends to the outer side of the mounting slot, and a sorting motor for driving the transfer frame to rotate is installed on the outer wall of the base.

[0011] Preferably, a second spring is provided on the outer wall of one side of the triangular magnetic block located in the mounting groove, and an abutment block is fixed on the outer wall of the end of the second spring away from the triangular magnetic block.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. The present invention, through its feeding mechanism, enables the bottom guard plate in the storage tank to fall onto the receiving frame when the interceptor plate moves the floating frame below the storage tank. The floating frame then moves the guard plate towards the clamp seat on the transfer frame and passes under the storage cylinder. At this point, the guard plate pushes the interceptor rod upward, thereby opening the bottom outlet of the storage cylinder. When the mounting hole on the guard plate aligns with the bottom outlet of the storage cylinder, the bottom bolt in the storage cylinder slides into the mounting hole on the guard plate. This achieves the effect of feeding the guard plate and bolt in one go. Furthermore, the positioning rod automatically completes the positioning before feeding, shortening the assembly steps of the flat-jaw pliers and greatly improving work efficiency.

[0015] 2. The present invention uses an intercepting rod to ensure that, in the initial state, the floating frame is located below the storage tank. At this time, under the action of the coil spring, the intercepting rod blocks the bottom outlet of the storage cylinder. When the intercepting plate moves the floating frame closer to the transfer frame, the guard plate on the receiving frame pushes the intercepting rod to rotate, thereby opening the bottom outlet of the storage cylinder. At the same time, the intercepting rod drives the pressure rod to press the storage cylinder, achieving the effect of limiting and locking the storage cylinder. This prevents the positioning rod from losing its positioning effect after the last guard plate in the storage tank is loaded, thus avoiding the situation where the storage cylinder shifts.

[0016] 3. This invention, through the auxiliary mechanism, ensures that when the protective plate falls onto the receiving frame, it abuts against the triangular magnetic block. The magnetic attraction of the triangular magnetic block ensures that the protective plate will not fall off the receiving frame, thus guaranteeing the stability of the device. When the pressure sensor's detection value is greater than the threshold, it indicates that the protective plate is installed correctly. At this time, the pressure sensor drives the sorting motor to rotate the transfer frame to one side of the discharge port via the controller signal. Similarly, when the pressure sensor's detection value is less than the threshold, it indicates that the protective plate is not installed correctly. At this time, the pressure sensor drives the sorting motor to rotate the transfer frame to the other side of the discharge port via the controller signal, thereby achieving the effect of automatic sorting of the flat-jaw pliers after the protective plate is assembled.

[0029] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0030] See Figures 1 to 10 As shown, an assembly device for manufacturing flat-jaw pliers includes a base 1. A transfer frame 2 for clamping a plier seat 9 is rotatably connected to the outer wall of the base 1. A storage trough 11 for stacking guard plates 91 is provided on the outer wall of the base 1. A second electric push rod 3 is installed on the top outer wall of the storage trough 11. A pair of fastening motors 31 are fixedly installed on the outer wall of the output end of the second electric push rod 3. Each fastening motor 31 has a mating block 32 on the shaft end wall that can rotate a bolt 92 through an internal hexagonal groove. The base 1 is provided with a feeding mechanism and an auxiliary mechanism. A positioning groove 22 facing the storage trough 11 is opened on the outer wall of the transfer frame 2. A first electric push rod 23 is fixed on the inner wall of the positioning groove 22. A clamping plate 24 for fixing the plier seat 9 is installed on the outer wall of the output end of the first electric push rod 23.

[0031] The feeding mechanism includes an intercepting plate 4 slidably inserted into the outer wall of the base 1. The intercepting plate 4 abuts against the bottom end of the storage trough 11. A floating frame 5 is slidably inserted into the outer wall of the intercepting plate 4 near the transfer frame 2. A pair of receiving frames 53 for receiving the protective plate 91 are slidably connected to the outer wall of the floating frame 5 away from the intercepting plate 4. A pair of storage cylinders 13 for arranging and storing bolts 92 are slidably inserted into the outer wall of the storage trough 11 near the transfer frame 2. The bottom ends of the storage trough 11 and the storage cylinders 13 are flush. A sliding rod 7 is slidably inserted into the outer wall of each storage cylinder 13. A positioning rod 71 extending into the storage trough 11 is provided on the outer wall of each sliding rod 7 away from the storage cylinder 13. The positioning rod 71 is slidably inserted into the mounting hole on the protective plate 91 inside the storage trough 11. A limiting block 112 for intercepting the floating frame 5 is provided on the wall. A linear motor 41 is installed on the outer wall of the base 1. The intercepting plate 4 is fixed on the outer wall of the output end of the linear motor 41. The linear motor 41 drives the intercepting plate 4 to move between the transfer frame 2 and the storage tank 11. A pair of symmetrically distributed guide grooves 42 are provided on the outer wall of the intercepting plate 4. A stroke groove 51 is provided on the outer wall of the floating frame 5 in the horizontal direction. A sliding column 531 is provided on the outer wall of each receiving frame 53, which is slidably inserted into the guide groove 42 and the stroke groove 51. A vertically upward limiting rod 43 is provided on the bottom outer wall of the intercepting plate 4. The floating frame 5 is slidably sleeved on the outer wall of the limiting rod 43. A first spring 52 sleeved on the outer wall of the limiting rod 43 is provided between the outer wall of the floating frame 5 and the outer wall of the intercepting plate 4.

[0032] It should be noted that in the initial state, the linear motor 41 drives the interceptor plate 4 to move away from the transfer frame 2. The interceptor plate 4 drives the floating frame 5 to move below the storage tank 11, so that the limit block 112 is engaged at the outer edge of the floating frame 5. This prevents the floating frame 5 from moving downward under the gravity of the guard plate 91 in the storage tank 11. The distance between the receiving frame 53 and the storage tank 11 is the thickness of one guard plate 91. At this time, the bottom guard plate 91 in the storage tank 11 falls onto the receiving frame 53, while the subsequent guard plates 91 remain in the storage tank 11. When the floating frame 5 drives the guard plate 91 to move towards the clamp seat 9 on the transfer frame 2, the interceptor plate 4 can block the storage tank 11. This process is repeated to achieve automatic feeding of the guard plate 91. The first spring 52 can bear the weight of one guard plate 91 and all components on the floating frame 5 without deformation.

[0033] Before assembly, the intercepting plate 4 is driven by the linear motor 41 to block the bottom outlet of the storage trough 11 and the storage cylinder 13. The protective plates 91 are stacked in the storage trough 11, and the bolts 92 are arranged axially in the storage cylinder 13. The positioning rod 71 is inserted into the mounting hole on the protective plate 91, so that the positioning rod 71 can automatically adjust the spacing between the storage cylinders 13 according to the spacing of the mounting holes on the protective plate 91, so as to achieve the effect of automatic positioning of the protective plate 91 and the bolts 92. The clamp seat 9 is placed vertically in the positioning groove 22 on the transfer frame 2 with the jaw side facing down. The clamping plate 24 is pushed by the first electric push rod 23 to clamp and fix the clamp seat 9, and the mounting hole at the jaw is aligned with the rotating shaft of the fastening motor 31. After the above-mentioned protective plate 91 loading process is completed, the intercepting plate 4 is driven by the linear motor 41. As the floating frame 5 moves closer to the transfer frame 2, the protective plate 91 moves closer to the clamp seat 9 on the transfer frame 2. When the floating frame 5 moves the protective plate 91 past the storage cylinder 13, the protective plate 91 pushes the intercepting rod 6 to deflect upward, thereby opening the bottom outlet of the storage cylinder 13. Since the storage cylinder 13 and the storage trough 11 are flush, the protective plate 91 on the receiving frame 53 will continue to block the storage cylinder 13. When the mounting hole on the protective plate 91 is aligned with the bottom outlet of the storage cylinder 13, the lowest bolt 92 in the storage cylinder 13 slides into the mounting hole on the protective plate 91, while the remaining bolts 92 remain in the storage cylinder 13. This achieves the effect of feeding the protective plate 91 and bolts 92 at one time. Furthermore, the positioning is automatically completed by the positioning rod 71 before feeding, shortening the assembly steps of the flat-jaw pliers and greatly improving work efficiency.

[0034] The sorting motor 21 is a stepper motor with a self-locking mechanism. In the initial state, the sorting motor 21 drives the positioning groove 22 on the transfer frame 2 to face the side where the storage trough 11 is located, so that the jaws of the clamp seat 9 are automatically aligned with the guard plate 91 in the storage trough 11. When the floating frame 5 moves the guard plate 91 to abut against the inner wall of the jaws of the clamp seat 9, the guard plate 91 and the clamp seat 9 complete the hole alignment process. The second electric push rod 3 is activated to extend downward. The second electric push rod 3 drives the mating block 32 on the fastening motor 31 to insert into the recess on the bolt 92. Inside the slot, the fastening motor 31 is started and the first electric push rod 23 is extended, causing the bolt 92 to rotate and move downwards, so that the bolt 92 is screwed into the mounting hole on the clamp seat 9 and the guard plate 91 is fixed. As the bolt 92 is tightened, the guard plate 91 pushes the two receiving brackets 53 to move downwards, so that the two receiving brackets 53 gradually move away from each other along the guide groove 42 through the sliding column 531, thereby allowing the receiving brackets 53 to avoid the guard plate 91, ensuring that the guard plate 91 can be installed in a state of complete contact with the clamp seat 9.

[0035] A fixing sleeve 111 is provided on the outer wall of the storage tank 11. An intercepting rod 6 is rotatably connected to the outer wall of the storage tank 11 via a rotating shaft. The intercepting rod 6 is used to block the bottom outlet of the storage cylinder 13. A coil spring 61 for resetting the intercepting rod 6 is provided between the outer wall of the rotating shaft of the intercepting rod 6 and the inner wall of the fixing sleeve 111. A pressure rod 62 that can abut against the storage cylinder 13 is provided on the outer wall of the intercepting rod 6.

[0036] It should be noted that in the initial state, the floating frame 5 is located below the storage tank 11. At this time, under the action of the coil spring 61, the intercepting rod 6 blocks the bottom outlet of the storage cylinder 13.

[0037] When the interceptor plate 4 moves the floating frame 5 closer to the transfer frame 2, the guard plate 91 on the receiving frame 53 pushes the interceptor rod 6 to rotate, so that the bottom outlet of the storage cylinder 13 is opened. At the same time, the interceptor rod 6 drives the pressure rod 62 to press the storage cylinder 13, thereby achieving the effect of limiting and locking the storage cylinder 13. This prevents the positioning rod 71 from losing its positioning effect after the last guard plate 91 in the storage trough 11 is filled, which would cause the storage cylinder 13 to shift.

[0038] The auxiliary mechanism includes a mounting groove 54 inside the floating frame 5. A pressure sensor 541 is fixed on the inner wall of the mounting groove 54. A triangular magnetic block 55 capable of adsorbing the guard plate 91 is slidably inserted into the inner wall of the mounting groove 54 near the transfer frame 2. The tip of the triangular magnetic block 55 extends to the outside of the mounting groove 54. A sorting motor 21 for driving the transfer frame 2 to rotate is installed on the outer wall of the base 1. A second spring 551 is provided on the outer wall of the side of the triangular magnetic block 55 located in the mounting groove 54. An abutment block 552 is fixed on the outer wall of the end of the second spring 551 away from the triangular magnetic block 55. The abutment block 552 abuts against the sensing surface of the pressure sensor 541. The pressure sensor 541 is electrically connected to the sorting motor 21 through a controller signal. A pair of symmetrically distributed discharge ports 12 are provided on the outer wall of the base 1 on both sides of the transfer frame 2.

[0039] It should be noted that when the protective plate 91 falls onto the receiving frame 53, the protective plate 91 abuts against the triangular magnetic block 55. The magnetic attraction of the triangular magnetic block 55 ensures that the protective plate 91 will not fall off the receiving frame 53, guaranteeing the stability of the device. During the installation of the protective plate 91, as the bolts 92 are tightened, the protective plate 91 pushes the floating frame 5 downwards through the receiving frame 53, causing the tip of the triangular magnetic block 55 to be positioned between the contact surfaces of the protective plate 91 and the clamp seat 9. When the protective plate 91 is in place, it fully abuts against the clamp seat 9. The gap between the protective plate 91 and the clamp seat 9 is insufficient to accommodate the triangular magnetic block 55, thus pushing the triangular magnetic block 55 completely into the mounting groove 54. At this time, the second spring 551 is highly compressed, resulting in a large detection value from the pressure sensor 541. Similarly, when the protective plate... When the guard plate 91 is not installed correctly, there is a gap between the guard plate 91 and the clamp seat 9. At this time, the triangular magnetic block 55 stays in the gap between the guard plate 91 and the clamp seat 9, and the detection value of the pressure sensor 541 is small. This causes the detection value of the pressure sensor 541 to be compared with the preset value. When the detection value is greater than the threshold, it means that the guard plate 91 is installed correctly. At this time, the pressure sensor 541 drives the sorting motor 21 to turn the transfer frame 2 to the discharge port 12 on one side through the controller signal. Similarly, when the detection value of the pressure sensor 541 is less than the threshold, it means that the guard plate 91 is not installed correctly. At this time, the pressure sensor 541 drives the sorting motor 21 to turn the transfer frame 2 to the discharge port 12 on the other side through the controller signal, thereby realizing the effect of automatic sorting of the flat jaw clamp after the guard plate 91 is assembled.

[0040] Working principle: Before assembly, the intercepting plate 4 is driven by the linear motor 41 to block the bottom outlet of the storage tank 11 and the storage cylinder 13. The guard plate 91 is stacked in the storage tank 11. The clamp seat 9 is placed vertically in the positioning slot 22 on the transfer frame 2 with the jaw side facing down. The clamp plate 24 is pushed by the first electric push rod 23 to clamp and fix the clamp seat 9, and the mounting hole at the jaw is aligned with the rotating shaft of the fastening motor 31.

[0041] Under the action of the feeding mechanism, the linear motor 41 drives the intercepting plate 4 to move away from the transfer frame 2. The intercepting plate 4 drives the floating frame 5 to move below the storage tank 11, so that the limiting block 112 is engaged with the outer edge of the floating frame 5, thus preventing the floating frame 5 from moving downward under the gravity of the guard plate 91 in the storage tank 11. The distance between the receiving frame 53 and the storage tank 11 is the thickness of one guard plate 91. At this time, the bottom guard plate 91 in the storage tank 11 falls onto the receiving frame 53, while the subsequent guard plates 91 remain in the storage tank 11. After the above guard plate 91 feeding process is completed, the linear motor 41 drives the intercepting plate 4 to move closer to the transfer frame 2, so that the floating frame 5 drives the guard plate 91 to move away from the transfer frame 2. When the clamp seat 9 on the transfer frame 2 approaches, and the floating frame 5 drives the guard plate 91 past the storage cylinder 13, the guard plate 91 pushes the intercepting rod 6 to deflect upward, thereby opening the bottom outlet of the storage cylinder 13. Since the storage cylinder 13 and the storage trough 11 are flush, the guard plate 91 on the receiving frame 53 will continue to block the storage cylinder 13. When the mounting hole on the guard plate 91 is aligned with the bottom outlet of the storage cylinder 13, the lowest bolt 92 in the storage cylinder 13 slides into the mounting hole on the guard plate 91, while the remaining bolts 92 remain in the storage cylinder 13. This achieves the effect of one-time loading of the guard plate 91 and bolts 92. Furthermore, the positioning is automatically completed by the positioning rod 71 before loading, shortening the assembly steps of the flat-jaw pliers and greatly improving work efficiency.

[0042] When the interceptor plate 4 moves the floating frame 5 closer to the transfer frame 2, the guard plate 91 on the receiving frame 53 pushes the interceptor rod 6 to rotate, so that the bottom outlet of the storage cylinder 13 is opened. At the same time, the interceptor rod 6 drives the pressure rod 62 to press the storage cylinder 13, thereby achieving the effect of limiting and locking the storage cylinder 13. This prevents the positioning rod 71 from losing its positioning effect after the last guard plate 91 in the storage trough 11 is filled, which would cause the storage cylinder 13 to shift.

[0043] Under the action of the auxiliary mechanism, when the guard plate 91 falls onto the receiving frame 53, the guard plate 91 abuts against the triangular magnetic block 55. The magnetic attraction of the triangular magnetic block 55 ensures that the guard plate 91 will not fall off the receiving frame 53, guaranteeing the stability of the device. During the installation of the guard plate 91, as the bolts 92 are tightened, the guard plate 91 pushes the floating frame 5 downwards through the receiving frame 53, causing the tip of the triangular magnetic block 55 to be positioned between the contact surfaces of the guard plate 91 and the clamp seat 9. When the guard plate 91 is in place, it fully abuts against the clamp seat 9. The gap between the guard plate 91 and the clamp seat 9 is insufficient to accommodate the triangular magnetic block 55, thus pushing the triangular magnetic block 55 completely into the mounting groove 54. At this time, the compression degree of the second spring 551 is large, resulting in a large detection value for the pressure sensor 541. Similarly, when… When the guard plate 91 is not installed correctly, there is a gap between the guard plate 91 and the clamp seat 9. At this time, the triangular magnetic block 55 stays in the gap between the guard plate 91 and the clamp seat 9, and the detection value of the pressure sensor 541 is small. This causes the detection value of the pressure sensor 541 to be compared with the preset value. When the detection value is greater than the threshold, it means that the guard plate 91 is installed correctly. At this time, the pressure sensor 541 drives the sorting motor 21 to turn the transfer frame 2 to the discharge port 12 on one side through the controller signal. Similarly, when the detection value of the pressure sensor 541 is less than the threshold, it means that the guard plate 91 is not installed correctly. At this time, the pressure sensor 541 drives the sorting motor 21 to turn the transfer frame 2 to the discharge port 12 on the other side through the controller signal, thereby realizing the effect of automatic sorting of the flat jaw clamp after the guard plate 91 is assembled.

[0044] When the floating frame 5 moves the guard plate 91 to abut against the inner wall of the jaw of the clamp seat 9, the guard plate 91 and the clamp seat 9 complete the hole alignment process. The second electric push rod 3 is activated to extend downward. The second electric push rod 3 drives the mating block 32 on the fastening motor 31 to insert into the groove on the bolt 92. The fastening motor 31 is activated and the first electric push rod 23 is further controlled to extend, so that the bolt 92 rotates and moves downward, thereby screwing the bolt 92 into the mounting hole on the clamp seat 9 and fixing the guard plate 91. As the bolt 92 is tightened.
