Description

Technical Field

[0001] This invention belongs to the technical field of screw plug production equipment, and more specifically, relates to a screw plug assembly device. Background Technology

[0002] Plugs are used to connect two or more parts, often to seal off unnecessary openings in pipes. Plugs typically contain a retaining ring and a steel ball. Current plug installation methods involve workers inserting the steel ball into the plug and then using pliers to install the retaining ring. This current method of plug assembly is primarily manual, resulting in low efficiency. Summary of the Invention

[0003] The purpose of this invention is to provide a screw plug assembly device, which aims to solve the problem of low efficiency in existing screw plug assembly methods.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is: to provide a screw plug assembly device, comprising: Base; A base connected to the machine base, the base having an assembly slot for holding steel balls, snap rings and screw plugs; Assembly mechanism; which is connected to the base; and A top seat is connected to the assembly mechanism, which drives the top seat into or away from the assembly slot.

[0005] In one possible implementation, a steel ball feeding mechanism is connected to the machine base; the steel ball feeding mechanism includes: A storage bin is connected to the base; the bottom of the storage bin has a steel ball discharge port for all steel balls to be discharged sequentially. Control components, which are slidably connected to the base; and The discharge guide rail is connected to the machine base and is received by the steel ball discharge port and the assembly groove.

[0006] In one possible implementation, the steel ball feeding mechanism further includes: a first mounting base connected to the machine base, the storage bin and the discharge guide rail both connected to the first mounting base, and the control component slidably connected to the first mounting base.

[0007] In one possible implementation, the storage bin is tilted.

[0008] In one possible implementation, a snap ring feeding mechanism is further included, which is disposed on the machine base; a snap ring inlet is provided on one side of the base, and the snap ring inlet communicates with the assembly slot; the snap ring feeding mechanism includes: A retaining ring storage element is connected to the base, and the retaining ring storage element is vertically arranged; A second mounting base is connected to the base and is disposed below the snap ring storage member. The snap ring stored in the snap ring storage member can fall onto the second mounting base. A retaining ring feeder is slidably disposed between the second mounting base and the retaining ring storage component; the retaining ring feeder is used to push the retaining ring on the second mounting base into the assembly slot through the retaining ring feed port.

[0009] In one possible implementation, a gap for storing the retaining ring is provided between the second mounting base and the retaining ring storage member.

[0010] In one possible implementation, a limiting member is connected to the second mounting base, the limiting member being disposed on one side of the snap ring feed member, the limiting member being used to restrict the sliding direction of the snap ring feed member.

[0011] In one possible implementation, a drive mechanism is also included, which includes: A drive unit, which is connected to the control unit and the snap ring feed unit; A drive spring, one end of which is connected to the drive component and the other end of which is connected to the base; The traction rope has one end connected to the drive component and the other end connected to the top seat or assembly mechanism. When the assembly mechanism drives the top seat into the assembly slot, the traction rope drives the snap ring feeder and the control component to slide through the drive component. When the assembly mechanism drives the top seat away from the assembly slot, the drive spring drives the drive component to reset.

[0012] In one possible implementation, the control component has a receiving groove, and the control component has a feeding groove on the side near the steel ball outlet and a discharge groove on the other side away from the steel ball outlet; the feeding groove and the discharge groove are offset.

[0013] In one possible implementation, when the assembly mechanism drives the top seat into the assembly slot, the driving member drives the snap ring feeder to slide out of the snap ring feed port so that the snap ring falls on the second mounting seat. The driving member drives the control member to slide so that the feed slot coincides with the steel ball discharge port so that the steel ball enters the receiving slot from the steel ball feed port. When the assembly mechanism drives the top seat away from the assembly slot, the drive spring drives the drive component to reset, and the drive component drives the snap ring feeder to push the snap ring on the second mounting seat from the snap ring feed port into the assembly slot. The drive component drives the control component to slide so that the discharge slot coincides with the feed guide rail, so that the steel ball enters the feed guide rail from the receiving slot.

[0014] The beneficial effects of the screw plug assembly device provided by this invention are as follows: Compared with the prior art, the screw plug assembly device of this invention reduces the use of manpower. Workers only need to place the steel ball, retaining ring, and screw plug into the assembly groove of the base, and then use the assembly mechanism to drive the top seat to press into the assembly groove. During the pressing process, the top seat presses the retaining ring and steel ball into the screw plug and fixes them in the designated position, thereby completing the screw plug assembly. The assembly process does not require workers to use pliers to insert the retaining ring into the screw plug, thus improving the efficiency of screw plug assembly. Attached Figure Description

[0018] To make the technical problems to be solved, the technical solutions, and the beneficial effects of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and are not intended to limit the present invention.

[0019] Reference Figure 1 and Figure 8 The screw plug assembly device provided by the present invention will now be described. The screw plug assembly device includes a base 1, a base 2 mounted on the base 1, an assembly mechanism 3, and a top seat 4 mounted on the assembly mechanism 3. The base 1 includes a base plate, a fixing seat bolted to the base plate, a vertical plate welded to the base plate, and a horizontal plate welded to the vertical plate, the horizontal plate being located directly above the base plate. A mounting groove is provided on the fixing seat, and the base 2 is fixed inside the mounting groove. An upward-opening assembly groove 21 is formed on the base 2. The assembly mechanism 3 is a cylinder mounted on the horizontal plate, and the top seat 4 is fixed to the piston rod of the cylinder by threaded connection or welding. The piston rod can push the top seat 4 into the assembly groove 21 or lift the top seat 4 from the assembly groove 21.

[0020] It should be noted that in this embodiment, the cylinder is used as an example to describe the assembly mechanism 3. Those skilled in the art can also use other devices, such as hydraulic cylinders or other structures and devices, as long as they can push the top seat 4 into the assembly slot 21 or lift the top seat 4 out of the assembly slot 21.

[0021] Compared with existing technologies, the screw plug assembly device provided by this invention allows workers to place the steel ball, retaining ring, and screw plug into the assembly groove 21 in a specific order during assembly. The assembly mechanism 3 then presses the top seat 4 into the assembly groove 21, thus completing the screw plug assembly. This invention eliminates the need for workers to use calipers to install the retaining ring; they only need to place the steel ball, retaining ring, and screw plug into the assembly groove 21, and then control the assembly mechanism 3 to press the top seat 4 into the assembly groove 21. This simplifies the worker's operation and improves the efficiency of screw plug assembly.

[0022] Reference Figure 1 and2 In a preferred embodiment, the plug assembly device further includes a steel ball feeding mechanism 5 disposed on one side of the fixed base. The steel ball feeding mechanism 5 includes a first mounting base 54 bolted to the fixed base, and a storage bin 51, a control element 52, and a discharge guide rail 53 mounted on the first mounting base 54. A mounting base is bolted to the top of the first mounting base 54. The storage bin 51 and the discharge guide rail 53 are mounted on the mounting base, and a space is reserved between the storage bin 51 and the discharge guide rail 53 for mounting the control element 52. The control element 52 overlaps the mounting base and can slide horizontally along the mounting base in a direction perpendicular to the discharge guide rail 53.

[0023] Both the storage chamber 51 and the discharge guide rail 53 are inclined, with the inclination angle of the storage chamber 51 being greater than that of the discharge guide rail 53. The side of the storage chamber 51 and the discharge guide rail 53 closest to the base 2 is lower than the other side. A steel ball discharge port 511 is located at the bottom of the storage chamber 51, corresponding to the discharge guide rail 53. The end of the discharge guide rail 53 closest to the fixed base is located above the fixed base. The width of the steel ball discharge port 511 and the discharge guide rail 53 is equal to the diameter of the steel ball. Steel balls can only flow out one at a time from the steel ball discharge port 511 and flow in a single row within the discharge guide rail 53.

[0024] Under the influence of gravity, the steel balls in the storage compartment 51 flow out one by one from the steel ball outlet 511. Under the control of the control component 52, only one steel ball can flow into the discharge guide rail 53 at a time. After entering the discharge guide rail 53, the steel ball is guided by the discharge guide rail 53 to enter the interior of the assembly tank 21 from the top of the assembly tank 21.

[0025] Reference Figure 2 and 3 One side of the control component 52 abuts against the steel ball outlet 511, and the other side abuts against the discharge guide rail 53. The control component 52 has a receiving groove 521, a feeding groove 522 on the side of the control component 52 near the storage compartment 51, and a discharge groove 523 on the other side of the control component 52. Both the feeding groove 522 and the discharge groove 523 communicate with the receiving groove 521. The control component 52 is elongated. The receiving groove 521 can accommodate multiple steel balls along the length of the control component 52, but can only accommodate one steel ball in the direction perpendicular to the control component 52. Only one steel ball is allowed to pass through the feeding groove 522 and the discharge groove 523 at a time. The feed chute 522 and the discharge chute 523 are misaligned. That is, when the feed chute 522 is aligned with the steel ball discharge port 511, the discharge chute 523 is misaligned with the discharge guide rail 53, and the steel balls in the receiving chute 521 cannot enter the discharge guide rail 53; when the discharge chute 523 is aligned with the discharge guide rail 53, the feed chute 522 is misaligned with the steel ball discharge port 511, and the steel balls cannot enter the receiving chute 521 from the feed chute 522.

[0026] The storage chamber 51 can store a large number of steel balls. Due to the inclined design of the storage chamber 51 and the low height of the steel ball outlet 511, the steel balls flow out from the outlet 511 under the influence of gravity. During assembly, by controlling the position of the control component 52, only one steel ball is fed into the discharge guide 53 at a time. The inclination angle of the discharge guide 53 is smaller than that of the storage chamber 51, which prevents the rolling speed of the steel balls from being too high and avoids the steel balls jumping out of the storage tank. Utilizing the steel balls' own gravity to flow from the storage chamber 51 into the assembly tank 21 eliminates the need for a dedicated drive structure and energy source, simplifying the structure and saving energy.

[0027] Reference Figure 1 and 4 In a preferred embodiment, the plug assembly device further includes a snap ring feeding mechanism 6 mounted on the base 1. The snap ring feeding mechanism 6 includes: a snap ring storage member 61 mounted on the upright plate, a second mounting base 62 mounted on a fixed base, a snap ring feed member disposed between the second mounting base 62 and the snap ring storage member 61, and a limiting member 64 bolted to the second mounting base 62. The snap ring storage member 61 is mounted on the upright plate via a connector, one end of which is welded to the snap ring storage member 61, and the other end is welded to the upright plate.

[0028] The snap ring storage component 61 is vertically arranged, and a guide post adapted to the shape of the snap ring is provided on the snap ring storage component 61. The snap ring is sleeved on the guide post, and the snap ring can fall directly onto the second mounting base 62 from the guide post. It should be noted that the shape of the snap ring storage component 61 in this embodiment is only illustrative and not limiting. Those skilled in the art can use other shapes, such as a vertical storage groove on the snap ring storage component 61. The storage groove is a through groove, and its shape is adapted to the shape of the snap ring, so that the snap ring can fall directly onto the second mounting base 62 from the storage groove.

[0029] Reference Figure 5 and 6 A gap is provided between the retaining spring storage component 61 and the second mounting base 62. This gap is greater than or equal to the thickness of one retaining spring and less than the thickness of two retaining springs. The retaining spring feed component 63 is disposed in the gap between the retaining spring storage component 61 and the second mounting base 62. A retaining spring feed port 22 is provided on the side of the base 2 and the fixed seat, and the bottom of the retaining spring feed port 22 is flush with the top of the second mounting base 62.

[0030] Reference Figure 7Two limiting members 64 are bolted to the second mounting base 62, and the two limiting members 64 are respectively located on both sides of the retaining ring feed member 63. The distance between the two limiting members 64 is equal to the width of the retaining ring feed member 63. A fixing member is bolted above the two limiting members 64, and the fixing member is located on the side away from the mounting base. The distance between the fixing member and the second mounting base 62 is equal to the thickness of the retaining ring feed member 63. The thickness of the retaining ring feed member 63 is less than or equal to the thickness of one retaining ring. The retaining ring feed member 63 can slide between the two limiting members 64, thereby pushing the retaining ring located at the bottom of the retaining ring storage member 61 into the assembly groove 21 through the retaining ring feed port.

[0031] Gravity is used to automatically drop the snap ring onto the second mounting base 62. At the same time, the distance between the second mounting base 62 and the snap ring storage component 61 is controlled so that the snap ring feeder 63 can only push one snap ring at a time. No additional material picking structure or driving energy is required. The structure is simple, saves energy, and reduces costs.

[0032] It should be noted that the limiting member 64 and the fixing member used to limit the circlip feed member 63 in this embodiment are only illustrative. Those skilled in the art can also use other methods. For example, the limiting member 64 can be a T-shaped slide rail or a dovetail slide rail fixed on the upper surface of the second mounting base 62, and a T-shaped groove or a dovetail groove can be provided on the lower surface of the circlip feed member 63. The circlip feed member 63 can be limited and slid by the slide rail and the groove.

[0033] Reference Figure 8 In a preferred embodiment, the screw plug assembly mechanism 3 further includes a drive mechanism 7 for sliding the control component 52 and the snap ring feed component 63. The drive mechanism 7 includes a drive component 71, a traction rope 73 connected to the drive component 71, a drive spring 72, and three guide wheels. Both the control component 52 and the snap ring feed component 63 are bolted to the drive component 71. Two drive springs 72 are provided. The two drive springs 72 are respectively located at both ends of the drive component 71 and on both sides of the mounting base. One end of each drive spring 72 is connected to the drive component 71, and the other end is bolted to the mounting base on the machine base 1.

[0034] A through hole is provided at the top and bottom of the upright plate. A guide wheel is installed on the lower surface of the horizontal plate, and two guide wheels are installed on the side of the upright plate away from the fixed seat. The two guide wheels correspond to the positions of the two through holes. One end of the traction rope 73 is connected to the top seat 4 or the piston head of the cylinder, and the other end passes sequentially through the guide wheel on the horizontal plate, the through hole and guide wheel at the top of the upright plate, and the through hole and guide wheel at the bottom of the upright plate before connecting to the drive component 71.

[0035] During the initial assembly, the top seat 4 is at its highest point, and the drive unit 71 is positioned closest to the fixed seat. At this time, the feed groove 522 in the control unit 52 coincides with the ball discharge port 511, and the balls in the storage chamber 51 enter the receiving groove 521 through the ball discharge port 511 and the feed groove 522. The retaining ring on the retaining ring storage unit 61 rests on the retaining ring feed unit 63. At this time, the operator manually places the retaining ring, balls, and screw plug into the assembly groove 21. Subsequently, the assembly mechanism 3 is activated, which pushes the top seat 4 into the assembly groove 21, thereby assembling the screw plug.

[0036] During this process, as the height of the top seat 4 gradually decreases, the traction rope 73 drives the drive component 71 away from the fixed seat. Simultaneously, the drive component 71 drives the control component 52 and the snap ring feed component 63 to slide, stretching the drive spring 72. The feed groove 522 on the control component 52 gradually de-aligns with the ball discharge port 511, and the discharge groove 523 gradually aligns with the discharge guide rail 53. When the height of the top seat 4 is at its lowest, the feed groove 522 and the ball discharge port 511 are completely de-aligned, and the discharge groove 523 and the discharge guide rail 53 are completely aligned. The balls at the ball discharge port 511 cannot enter the receiving groove 521. The balls in the receiving groove 521 enter the discharge guide rail 53 through the discharge groove 523, and the balls begin to roll towards the assembly groove 21 in the discharge guide rail 53. The drive spring 72 is the longest. When the top seat 4 is at its lowest height, the snap ring feeder 63 is at its furthest distance from the base 2. At this time, the snap ring feeder 63 is located on the side of the snap ring storage piece 61 away from the base 2, and the snap ring on the snap ring storage piece 61 falls onto the second mounting seat 62. Afterwards, the assembly mechanism 3 carries the top seat 4 out of the assembly slot 21 and back to its initial position. During this process, the traction rope 73 loses its traction force, and the drive spring 72 drives the drive piece 71 to reset. During this process, the snap ring feeder 63 pushes the snap ring on the second mounting seat 62 into the assembly slot 21 through the snap ring feed port 22. A steel ball rolls onto the discharge guide rail 53 into the assembly slot 21. The drive piece drives the control piece 52 to reset. At this time, the feed slot 522 re-aligns with the steel ball discharge port 511, and the discharge slot 523 is completely disaligned with the discharge guide rail 53, allowing a steel ball to enter the receiving slot 521. Driven by the drive unit 71, the steel ball feeding mechanism 5 and the snap ring feeding mechanism 6 complete the work of supplying steel balls and snap rings to the assembly slot 21. The operator only needs to add screw plugs to the assembly slot 21 and then control the assembly mechanism 3 to restart the assembly work.

[0037] During the use of this invention, the operator only needs to replenish steel balls, snap rings, and screw plugs into the assembly slot 21 during the first assembly process. In subsequent assembly operations, the drive mechanism 7 drives the steel ball feeding mechanism 5 and the snap ring feeding mechanism 6 to feed materials into the assembly slot 21. The operator only needs to replenish the screw plugs and control the assembly mechanism 3. This invention reduces the labor intensity of the operator, simplifies the operation, lowers the requirements for the operator in the assembly work, and improves the efficiency of screw plug assembly.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
