Description

Technical Field

[0001] This utility model belongs to the field of screw manufacturing technology, and in particular relates to a clamping device for screw manufacturing. Background Technology

[0002] In the production of screws, the screws need to be clamped at the tail. The existing clamping device requires the operator to manually install the screw onto the clamping device. After processing, the screw also needs to be manually removed. This requires two manual steps, which is a cumbersome process and puts a lot of labor intensity on the workers.

[0003] Chinese utility model patent CN219093886U includes a workbench with a base. A lower arc-shaped groove penetrating the base is formed on the upper surface of the base along a left-right direction. A pressure plate is slidably mounted above the base. A lifting mechanism is provided between the pressure plate and the workbench. An upper arc-shaped groove with the same inner diameter as the lower arc-shaped groove is formed on the lower surface of the pressure plate, corresponding vertically to the lower arc-shaped groove. A support plate is provided on the right side of the pressure plate, and a telescopic mechanism is provided on the support plate. The telescopic mechanism is connected to an iron push rod extending coaxially with the lower arc-shaped groove, and an electromagnet is connected to the iron push rod. This utility model replaces manual material feeding, reducing the labor intensity of operators.

[0004] However, the above-mentioned device has the following technical problems in actual use:

[0005] 1. The aforementioned device proposes that when the telescopic mechanism moves the sleeve away from the base, the screws inside the sleeve will naturally fall into the lower unloading window. However, in actual operation, after the screws are inserted into the sleeve, some screws will remain inside the sleeve. When the screws fall, they may be stuck in the sleeve due to the obstruction of the part inside the sleeve, and cannot fall down. Afterwards, manual removal is required, which increases the amount of manual labor. At the same time, the aforementioned device also lacks an ejection mechanism to push out the screws inside the sleeve.

[0006] Second, in addition, there is a certain height difference between the sleeve and the hopper below in the above device. When the screw falls, it will hit the hopper and may cause damage to the screw. At the same time, when there are many screws stored in the hopper, the collision between the screws will also cause damage to the screws. Utility Model Content

[0007] This utility model provides a clamping device for screw production, which aims to solve the problems mentioned in the background art. During the screw falling process, due to the large drop between the sleeve and the hopper, the screw may hit the inside of the hopper or collide with other screws, which can easily cause damage to the screw. At the same time, the lack of an ejection mechanism in the above-mentioned device may cause the screw to get stuck when it is detached from the sleeve, and manual removal is required afterward, which increases the workload.

[0008] This utility model is implemented as follows: a clamping device for screw production includes: a workbench with a material feeding groove, and a receiving box corresponding to the bottom of the material feeding groove; a processing mechanism on the workbench, comprising: a fixing component and a pushing component respectively disposed on both sides of the material feeding groove; the pushing component having: a movable seat and a sleeve slidably disposed within the movable seat; the sleeve partially accommodating screws; and a toggle component disposed on the movable seat, the toggle component being movably connected to the sleeve and used to drive the sleeve to move horizontally within the movable seat; a rotating block rotatably connected within the material feeding groove, and a receiving component disposed on the rotating block; the receiving component being used for... The device receives screws discharged from the sleeve. In this scheme, the tail end of the screw is inserted into the sleeve. Then, after the electromagnet is energized, the screw is attracted by the push rod. The output end of the second cylinder pushes the moving seat to move the screw towards the fixing component. After the screw is fixed by the fixing component, it is processed. After processing, the rotating disk rotates and the cooperation of the toggle block and toggle rod drives the sleeve to slide away from the fixing component along the push rod. At this time, the electromagnet is de-energized. When the end of the sleeve close to the fixing component is level with the end of the push rod on the same side, the screw will fall out of the sleeve and fall into the receiving box along the drop chute. This method can avoid the screw getting stuck inside the sleeve during the feeding process and reduce the amount of manual handling work afterwards.

[0009] In addition, in this device, a rotating block is rotatably installed inside the feeding trough. The rotation of the rotating block causes different receiving grooves on its outer peripheral wall to rotate sequentially to the top and receive the falling screws. The screws fall into the receiving grooves and then move out of the receiving grooves as the rotating block rotates, falling into the receiving box below. The purpose of setting up the rotating block (receiving groove) is to reduce the falling height of the screws and to receive the screws one by one, avoiding damage caused by the screws falling from a height and hitting the receiving box or other screws.

[0010] Preferably, the fixing component includes: a first fixing seat fixedly installed on the top wall of the workbench, the top wall of the first fixing seat having a first arc-shaped groove, a second fixing seat disposed above the first fixing seat, and the bottom wall of the second fixing seat having a second arc-shaped groove corresponding to the first arc-shaped groove, and a first cylinder fixedly installed on the workbench on both sides of the second fixing seat, and the output end of the first cylinder being fixedly connected to the second fixing seat; in this scheme, the height of the inner tube of the sleeve is consistent with the height of the center of the first arc-shaped groove and the second arc-shaped groove after they are closed. When it is necessary to clamp and fix the screw, the output ends of the first cylinders on both sides extend to push the second fixing seat upward and away from the first fixing seat. Then the screw approaches the first fixing seat and is inserted into the first arc-shaped groove. Then the output end of the first cylinder retracts to pull the second fixing seat closer to the first fixing seat, so that the second arc-shaped groove is stuck on the outside of the screw, cooperating with the first arc-shaped groove to surround and fix the screw.

[0011] Preferably, the pushing assembly further includes: a support base fixedly installed on the worktable, a sliding plate fixedly connected to the side wall of the support base facing the fixed assembly, a movable seat slidably disposed on the sliding plate, and a second cylinder fixedly connected to the side wall of the support base, the output end of which is fixedly connected to the side wall of the movable seat. A sliding groove is formed on the side wall of the movable seat, the sleeve is slidably connected in the sliding groove, and a pushing rod is fixedly connected to the side wall of the movable seat away from the fixed assembly. An electromagnet is fixedly connected to the outer wall of the pushing rod, and one end of the pushing rod extends... The push rod extends into the sliding groove and transitionally fits into the sleeve. In this design, the push rod is made of conductive material and is fixedly installed on the side wall of the movable seat away from the fixed component. One end of the push rod is exposed on the outside of the movable seat, and an electromagnet is fixedly connected to the outer wall. The electromagnet is electrically connected to an external power supply device. At the same time, the other end of the push rod is inserted into the sliding groove and extends into the sleeve (there is a certain gap between the end of the push rod near the fixed component and the end of the sleeve near the fixed component to facilitate screw insertion and fixing). The sleeve is slidably disposed in the sliding groove and slides outside the push rod.

[0012] It should be noted that when the tail end of the screw is inserted into the sleeve, it abuts against the end of the push rod. Then the electromagnet is energized, and the screw is fixed by electromagnetic attraction. Then the output end of the second cylinder pushes the moving seat to slide horizontally on the sliding plate and approach the fixing component. After the screw is fixed by the fixing component, it is convenient to carry out subsequent processing.

[0013] Preferably, the actuating assembly includes: a moving groove formed on the top wall of the moving seat and communicating with the sliding groove; an actuating rod fixedly connected to the outer wall of the sleeve and slidably disposed in the moving groove; a return spring sleeved on the outer side of the push rod between the sleeve and the sliding groove; a mounting block fixedly connected to the top wall of the moving seat; a first motor fixedly connected to its side wall; a rotating disk fixedly connected to the output end of the first motor; and multiple actuating blocks fixedly connected at equal angles on the outer peripheral wall of the rotating disk. In this embodiment, when the output end of the first motor rotates, it controls the rotating disk to rotate, and the rotating disk drives the multiple actuating blocks on its outer peripheral wall to rotate circumferentially. When one of the actuating blocks contacts the actuating rod, it drives the actuating rod to slide along the moving groove away from the fixed assembly. The actuating rod pulls the sleeve to move synchronously and slides outside the push rod. At this time, the return spring is gradually compressed. When the sleeve moves to a certain distance, the actuating block and the actuating rod separate, and the sleeve returns to its original position under the rebound action of the return spring.

[0014] It should be noted that the sliding of the sleeve makes the ends of the sleeve and the ejector rod on the same side level during the material feeding process, which prevents the tail end of the screw from getting stuck inside the sleeve. The ejector rod acts as a pusher, pushing the screw out of the sleeve.

[0015] Preferably, a limiting groove is formed on the inner side wall of the sleeve, and a limiting block is fixedly connected to the outer wall of the push rod. The limiting block is slidably disposed in the limiting groove. In this scheme, when the return spring rebounds, the limiting block and the limiting groove can play a limiting role, thereby preventing the sleeve from coming out of the sliding groove (and further preventing the sleeve and the push rod from separating).

[0016] Preferably, the receiving component includes: rotating shafts fixedly connected to both sides of the rotating block and rotatably connected to the material drop trough, and a second motor fixedly connected to the side wall of the workbench, the output end of the second motor being fixedly connected to the rotating shafts, and multiple material receiving grooves being formed at equal angles on the outer peripheral wall of the rotating block; in this scheme, when the output end of the second motor rotates, it drives the rotating block to rotate, and the rotating block controls the material receiving grooves to move one by one above the workbench, and to receive the screws falling from the sleeve.

[0017] Compared with the prior art, the beneficial effects of this utility model are: This utility model provides a clamping device for screw production.

[0018] 1. This device inserts the tail end of the screw into the sleeve. Then, after the electromagnet is energized, the screw is attracted by the push rod. The output end of the second cylinder pushes the moving seat to move the screw towards the fixing component. After the screw is fixed by the fixing component, it is processed. After processing, the rotating disk rotates and the cooperation of the toggle block and toggle rod drives the sleeve to slide away from the fixing component along the push rod. At this time, the electromagnet is de-energized. When the end of the sleeve close to the fixing component is level with the end of the push rod on the same side, the screw will fall out of the sleeve and fall into the receiving box along the drop chute. This method can avoid the screw getting stuck inside the sleeve during the feeding process and reduce the amount of manual handling work afterwards.

[0019] 2. In this device, a rotating block is rotatably installed inside the feeding trough. The rotation of the rotating block causes different receiving grooves on its outer peripheral wall to rotate sequentially to the top and receive the falling screws. The screws fall into the receiving grooves and then move out of the receiving grooves as the rotating block rotates, falling into the receiving box below. The purpose of setting up the rotating block (receiving groove) is to reduce the falling height of the screws and to receive the screws one by one, avoiding damage caused by the screws falling from a height and hitting the receiving box or other screws.
