Description
Technical Field
[0001] This utility model relates to the field of nut installation technology, and in particular to a hot melt nut driving device. Background Technology
[0002] To securely insert a nut into a plastic part, the nut must first be heated until its surface temperature exceeds the melting point of the plastic. Then, the nut is quickly driven into the plastic. During this process, the plastic melts instantly due to the high temperature, and a molten pool is formed at the point of contact between the two. After cooling, the nut and the plastic part are tightly bonded. During the process of driving the nut into the plastic, due to the excessively high surface temperature of the nut, a tool is needed to drive the nut into the plastic.
[0003] During the process of driving the nut into the plastic part, the worker needs to fix the plastic part to prevent it from shaking during the driving process, which would cause the nut to deviate. In the existing technology, in order to ensure efficiency, a groove is made on the surface of the worktable when fixing the plastic part, and the plastic part is placed in the groove for limiting. However, the plastic part is elastic and will deform during the driving process, and then shake in the groove, which will cause the nut to deviate. Utility Model Content
[0004] To solve the above problems, this utility model provides a hot melt nut driving device.
[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a hot melt nut driving device, including a base, a support block fixedly disposed on the upper surface of the base, a worktable fixedly disposed on the upper surface of the base, a slot opened on the upper surface of the worktable, a movable groove opened on the side wall of the support block near the worktable, a movable component slidably disposed in the movable groove, a plurality of heating rods fixedly disposed on the side wall of the movable component near the worktable, a cylinder fixedly disposed on the side wall of the support block, the piston rod of the cylinder passing through the support block and extending into the movable groove and fixed to the movable component, and a fixing device for fixing plastic parts disposed on the worktable.
[0006] By adopting the above technical solution, when workers need to drive the nut into the plastic part, they need to place the nut on a heating rod to heat it. Then, the workers place the plastic part into the slot. At this point, the workers use a fixing device to secure the plastic part in the slot. Once the plastic part is secured, the workers activate the cylinder, causing the piston rod to extend. This moves the moving part and the heating rod under the cylinder's action, driving the nut into the plastic part. After driving, the workers retract the piston rod. During this process, the fixing device secures the plastic part, reducing the probability of it shaking during driving and thus reducing the probability of deviation during nut driving.
[0007] Furthermore, the upper surface of the workbench is symmetrically provided with sliding grooves, and the inner wall of the sliding grooves is provided with fixing grooves. The fixing device includes a U-shaped fixing member that is slidably disposed in the two sliding grooves. The side wall of the U-shaped fixing member is provided with a blocking groove that is directly opposite to the fixing groove. The fixing device also includes a fixing rod with its two ends slidably disposed in the fixing groove and the blocking groove respectively, and a first spring fixedly disposed on the side wall of the fixing rod. The other end of the first spring is fixedly disposed on the inner wall of the fixing groove. The upper surface of the fixing rod has a first inclined surface on the edge where it intersects with the side wall away from the first spring.
[0008] By adopting the above technical solution, when workers need to fix plastic parts, they place the plastic parts into the slots. Then, the workers slide both ends of the U-shaped fixing member into the two grooves respectively, causing the U-shaped fixing member to gradually approach and eventually press against the first inclined surface. This allows the fixing rod to slide into the fixing groove under the action of the U-shaped fixing member. Subsequently, when the fixing groove and the blocking groove are aligned, one end of the fixing rod slides into the blocking groove under the action of the first spring, thus fixing the U-shaped fixing member in the groove. During this process, the upper and lower surfaces of the plastic part abut against the inner top wall of the U-shaped fixing member and the inner bottom wall of the slot, respectively, thereby fixing the plastic part.
[0009] Furthermore, a receiving groove is formed on the inner bottom wall of the fixing groove, and a rotating groove is formed through the inner wall of the receiving groove. A connecting piece is fixedly provided on the bottom surface of the fixing rod, a rotating rod is rotatably provided in the rotating groove, and a driving piece is fixedly provided on the outer wall of the rotating rod.
[0010] By adopting the above technical solution, after the nut is driven in, the worker needs to remove the plastic part. The worker needs to rotate the rotating rod, which in turn causes the driving component to rotate, thereby moving the connecting component under the action of the driving component. This, in turn, causes the fixing rod to slide away from the blocking groove under the action of the connecting component, thus separating the fixing rod from the blocking groove. At this time, the worker slides the U-shaped fixing component upward to separate the U-shaped fixing component from the sliding groove. Then, the worker can remove the plastic part.
[0011] Furthermore, an annular groove is formed on the inner wall of the rotating groove, and an annular block is rotatably arranged in the annular groove, the annular block being fixed to the rotating rod.
[0012] By adopting the above technical solution, when the operator rotates the rotating rod, the annular block rotates synchronously with the rotating rod under the action of the rotating rod. In this process, the annular block reduces the probability of the rotating rod moving, thereby improving the stability of the device.
[0013] Furthermore, a second spring is fixedly installed on the inner bottom wall of each of the two grooves, and the other end of each of the two second springs abuts against the bottom surface of the U-shaped fastener.
[0014] By adopting the above technical solution, when the fixing rod and the blocking groove are separated from each other, the U-shaped fixing part slides upward under the action of the second spring. During this process, the staff does not need to manually slide the U-shaped fixing part upward, thereby reducing the difficulty of the staff's work.
[0015] Furthermore, a limiting groove is formed on the inner top wall of the fixing groove, and a limiting block is slidably arranged in the limiting groove, and the limiting block is fixed to the fixing rod.
[0016] By adopting the above technical solution, when the fixed rod slides, the limiting block slides synchronously with the fixed rod. During this process, when the side wall of the limiting block abuts against the inner wall of the limiting groove, the first inclined surface is directly opposite the U-shaped fixing piece, thereby improving the stability of the device.
[0017] Furthermore, the lower end of the U-shaped fastener is chamfered.
[0018] By adopting the above technical solution, the chamfering reduces the difficulty for workers to slide the U-shaped fastener into the groove, thereby reducing the difficulty of the workers' work.
[0019] In summary, this utility model has the following beneficial effects:
[0020] 1. In this application, when a worker needs to drive a nut into a plastic part, the worker needs to place the nut on a heating rod to heat the nut. Then, the worker places the plastic part into a slot. At this point, the worker uses a fixing device to secure the plastic part in the slot. Once the plastic part is secured, the worker activates a cylinder, causing the piston rod to extend. This moves the moving part and the heating rod under the cylinder's action, driving the nut into the plastic part. After driving, the worker retracts the piston rod. During this process, the fixing device secures the plastic part, reducing the probability of the plastic part shaking during driving, thus reducing the probability of deviation during nut driving.
[0021] 2. In this application, when a worker needs to fix a plastic part, the worker places the plastic part into the slot. At this time, the worker slides both ends of the U-shaped fixing member into the two sliding grooves respectively, so that the U-shaped fixing member gradually approaches and finally presses against the first inclined surface, thereby causing the fixing rod to slide into the fixing groove under the action of the U-shaped fixing member. Subsequently, when the fixing groove and the blocking groove are aligned, the fixing rod slides one end into the blocking groove under the action of the first spring, thereby fixing the U-shaped fixing member in the sliding groove. During this process, the upper surface and the bottom surface of the plastic part abut against the inner top wall of the U-shaped fixing member and the inner bottom wall of the slot respectively, thereby fixing the plastic part.
[0022] 3. In this application, after the nut is driven in, the worker needs to remove the plastic part. The worker needs to rotate the rotating rod, which in turn causes the driving component to rotate, thereby moving the connecting component under the action of the driving component. This causes the fixing rod to slide away from the blocking groove under the action of the connecting component, thus separating the fixing rod from the blocking groove. At this time, the worker slides the U-shaped fixing component upward to separate the U-shaped fixing component from the sliding groove. Then, the worker can remove the plastic part.

[0028] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.
[0029] like Figure 1-4 As shown in the illustration, this application discloses a thermoplastic nut-driving device, including a base 1, a support block 11, a worktable 12, a movable component 13, a heating rod 14, a cylinder 15, a fixing device 3, a connecting component 4, a rotating rod 41, a driving component 42, an annular block 5, a second spring 6, and a limiting block 7. The base 1 is a rectangular plate structure, and the support block 11 is a cuboid structure, fixedly mounted on the upper surface of the base 1. The worktable 12 is a cuboid structure, fixedly mounted on the upper surface of the base 1. A movable groove 2 is formed on the side wall of the support block 11 near the worktable 12, and a slot 21 is formed on the upper surface of the worktable 12. The movable component 13 is a rectangular block structure, slidably mounted within the movable groove 2. Multiple heating rods 14 are provided and fixedly mounted on the side wall of the movable component 13 near the worktable 12, used for heating the nut. The cylinder 15 is fixedly mounted on the side wall of the support block 11, and the axis of its piston rod is horizontal. The piston rod of the cylinder 15 passes through the support block 11 and extends into the movable groove 2, where it is fixed to the movable part 13.
[0030] When the worker needs to drive the nut into the plastic part, the worker needs to put the nut on the heating rod 14 and heat the nut through the heating rod 14. Then, the worker puts the plastic part into the slot 21. At this time, the worker uses the fixing device 3 to fix the plastic part in the slot 21. After the plastic part is fixed in the slot 21, the worker needs to activate the cylinder 15, which causes the piston rod of the cylinder 15 to extend, thereby moving the movable part 13 and the heating rod 14 under the action of the cylinder 15, thus driving the nut into the plastic part. After driving it in, the worker can retract the piston rod of the cylinder 15. During this process, the fixing device 3 fixes the plastic part, thereby reducing the probability of the plastic part shaking during driving, and thus reducing the probability of deviation when driving the nut in.
[0031] The upper surface of the workbench 12 is symmetrically provided with sliding grooves 22, and the inner wall of the sliding grooves 22 is provided with fixing grooves 23. The U-shaped fixing member 31 has a U-shaped cross-section and is slidably disposed in the two sliding grooves 22. The side wall of the U-shaped fixing member 31 is provided with a blocking groove 24 that is directly opposite to the fixing groove 23. The fixing rod 32 is a rectangular rod structure, and its two ends are respectively slidably disposed in the fixing groove 23 and the blocking groove 24. One end of the first spring 33 is fixedly disposed on the side wall of the fixing rod 32, and the other end of the first spring 33 is fixedly disposed on the inner wall of the fixing groove 23. The upper surface of the fixing rod 32 has a first inclined surface 34 on the edge where it intersects with the side wall away from the first spring 33.
[0032] When workers need to fix the plastic part, they place the plastic part into the slot 21. At this time, the workers slide both ends of the U-shaped fixing member 31 into the two sliding grooves 22 respectively, so that the U-shaped fixing member 31 gradually approaches and finally presses against the first inclined surface 34, thereby causing the fixing rod 32 to slide into the fixing groove 23 under the action of the U-shaped fixing member 31. Subsequently, when the fixing groove 23 is aligned with the blocking groove 24, the fixing rod 32 slides one end into the blocking groove 24 under the action of the first spring 33, thereby fixing the U-shaped fixing member 31 in the sliding groove 22. During this process, the upper surface and the bottom surface of the plastic part abut against the inner top wall of the U-shaped fixing member 31 and the inner bottom wall of the slot 21 respectively, thereby fixing the plastic part.
[0033] A receiving groove 25 is provided on the inner bottom wall of the fixed groove 23, and a rotating groove 26 is provided through the inner wall of the receiving groove 25. The connecting piece 4 is fixedly installed on the bottom surface of the fixed rod 32. The rotating rod 41 is a round rod structure with its axis horizontal. The rotating rod 41 is rotatably installed in the rotating groove 26, and the driving piece 42 is fixedly installed on the outer wall of the rotating rod 41.
[0034] After the nut is driven in, the worker needs to remove the plastic part. The worker needs to rotate the rotating rod 41, which in turn causes the driving component 42 to rotate. This, in turn, moves the connecting component 4, causing the fixing rod 32 to slide away from the blocking groove 24 under the action of the connecting component 4, thus separating the fixing rod 32 from the blocking groove 24. At this point, the worker slides the U-shaped fixing component 31 upwards to separate it from the sliding groove 22. The worker can then remove the plastic part.
[0035] An annular groove 27 is provided on the inner wall of the rotating groove 26. The annular block 5 is rotatably disposed in the annular groove 27, and its axis coincides with the axis of the rotating rod 41. The annular block 5 and the rotating rod 41 are fixed to each other.
[0036] When the operator rotates the rotating rod 41, the annular block 5 rotates synchronously with the rotating rod 41 under the action of the rotating rod 41. During this process, the annular block 5 reduces the probability of the rotating rod 41 moving, thereby improving the stability of the device.
[0037] Two second springs 6 are provided. One end of each second spring 6 is fixedly mounted on the inner bottom wall of the two slide grooves 22, and the other end of each second spring 6 abuts against the bottom surface of the U-shaped fixing member 31.
[0038] When the fixing rod 32 separates from the blocking groove 24, the U-shaped fixing part 31 slides upward under the action of the second spring 6. During this process, the staff does not need to manually slide the U-shaped fixing part 31 upward, thereby reducing the difficulty of the staff's work.
[0039] A limiting groove 28 is provided on the inner top wall of the fixing groove 23. The limiting block 7 is a rectangular block structure. The limiting block 7 is slidably disposed in the limiting groove 28. The limiting block 7 is fixed to the fixing rod 32.
[0040] When the fixed rod 32 slides, the limiting block 7 slides synchronously with the fixed rod 32. During this process, when the side wall of the limiting block 7 abuts against the inner wall of the limiting groove 28, the first inclined surface 34 is directly opposite the U-shaped fixing member 31, thereby improving the stability of the device.
[0041] To reduce the difficulty of the work for the workers, the lower end of the U-shaped fastener 31 is provided with a chamfer 8. The chamfer 8 reduces the difficulty for the workers to slide the U-shaped fastener 31 into the slide groove 22, thereby reducing the difficulty of the workers' work.
[0042] The working principle of the hot-melt nut-driving device in this embodiment is as follows: When the worker needs to drive the nut into the plastic part, the worker needs to put the nut on the heating rod 14 and heat the nut through the heating rod 14. Then, the worker puts the plastic part into the slot 21. At this time, the worker fixes the plastic part in the slot 21 using the fixing device 3. After the plastic part is fixed in the slot 21, the worker needs to activate the cylinder 15, which causes the piston rod of the cylinder 15 to extend, thereby moving the movable part 13 and the heating rod 14 under the action of the cylinder 15, thus driving the nut into the plastic part. After driving, the worker can retract the piston rod of the cylinder 15. During this process, the fixing device 3 fixes the plastic part, thereby reducing the probability of the plastic part shaking during the driving process, and thus reducing the probability of deviation when driving the nut.
[0043] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
