Abstract
Description
Technical Field
[0001] This invention relates to the field of buoy assembly technology, specifically to a quick-installation device for an insertable positioning pin and its usage method. Background Technology
[0002] In the assembly process of a certain buoy depth-fixing component, the hook assembly is mainly done by manually pressing it into the pin hole of the φ2.1 depth-fixing ring using a φ2.3 pin. Currently, tweezers are used to hold the positioning pin and a modified flathead screwdriver to manually press it in place. During the assembly process, the concentricity of the hook pin hole and the depth-fixing ring pin hole is manually adjusted, and the force is controlled evenly by both hands. As a result, cases of misalignment due to non-vertical force and damage to parts due to excessive force often occur. The labor intensity is high, and the installation time for the two hooks of each depth-fixing component is about 2 to 3 minutes, which is inefficient and cannot meet the requirements of the assembly line cycle. Summary of the Invention
[0003] The technical problem to be solved by the present invention is to provide a quick installation device and method for inserting positioning pins. The quick installation device for inserting positioning pins can control the installation depth of the positioning pins, improve assembly consistency and quality, and can be used to quickly install two asymmetrical hooks of a fixed-depth ring, reduce labor intensity, improve production efficiency, and solve the problem of production line cycle time.
[0004] The technical solution of the present invention is to provide a quick installation device for an insertable positioning pin, the installation device comprising:
[0005] The depth ring and hook positioning mechanism is installed at the center of the installation device. The depth ring and hook positioning mechanism is provided with a depth ring positioning groove, a hook positioning post and a limiting hole. The depth ring positioning groove and hook positioning post are adapted to the size of the depth ring and hook to be assembled and can position them. The depth ring positioning groove and hook positioning post are matched with the size of the depth component. The size is determined according to the size of the depth ring and the installation position of the hook, so that the position of the depth ring and hook to be assembled is relatively fixed, which plays the role of concentricity of the mounting pin hole, thereby replacing manual intervention and adjustment during the assembly process.
[0006] The positioning pin insertion type propulsion mechanism includes a positioning pin insertion structure adapted to the installation dimensions of a positioning ring and a hook, a movable cavity, and a pin installed inside the movable cavity. The positioning pin insertion structure has an axially extending mechanism at its front end and an axially extending connecting end at its rear end. The extending mechanism and the positioning pin insertion structure each have an internal cavity through which the positioning pin to be assembled passes, and these cavities are interconnected. The positioning pin insertion structure also has a first inlet port that opens upwards at 90°, and the first inlet port connects with the positioning pin insertion mechanism. The deep-penetrating structural component is connected to the internal cavity, and the connecting end is connected to the front end of the movable cavity. The connecting end is connected to the movable cavity. A spring is sleeved on the ejector pin, and the rear end of the ejector pin has a cylindrical boss that cooperates with the spring. The outer diameter of the cylindrical boss is smaller than the inner diameter of the movable cavity. The function of the spring is to first push the fixed-depth insertion mechanism component into the fixed-depth ring mounting pin hole when the lever mechanism is pushed horizontally. After contacting the limit hole, the spring stops moving forward, and the horizontal thrust then pushes the ejector pin together with the positioning pin into the mounting pin hole, so as to realize the installation of the hooks on both sides in one step.
[0007] There are two lever mechanisms, located on both sides of the installation device. Each lever mechanism consists of a connecting rod and a pressure rod. The connecting rod is connected to the depth ring and the hook positioning mechanism, while the pressure rod is connected to the positioning pin insertion type propulsion mechanism. The pressure rod achieves horizontal concentric thrust through the connecting rod.
[0008] The stroke control mechanism has two parts, which are fixed on both sides of the mounting device. The stroke control mechanism is provided with a second inlet that matches the first inlet, and a slide chamber for the positioning pin insertion type propulsion mechanism to slide. The positioning pin insertion type propulsion mechanism is located in the slide chamber and slides with it. The positioning pin insertion type propulsion mechanism is driven by a pressure rod. The stroke control mechanism is also provided with a pressure rod stroke limit part that cooperates with the lever mechanism. The pressure rod stroke limit part is used to control the working stroke of the positioning pin insertion type propulsion mechanism.
[0009] This invention, through positioning with a depth-fixing ring and hook, centering and advancing with a positioning pin, stroke control, and lever function, ultimately reduces the assembly time of each depth-fixing component from the original 2-3 minutes to an average of 15 seconds, increasing efficiency by more than 8 times. This device significantly improves assembly efficiency, reduces manual labor intensity, and enhances quality consistency. Furthermore, the device is highly versatile.
[0010] Preferably, the limiting hole is a stepped hole, which includes a countersunk hole at the outer end that matches the outer diameter of the spring, and a reduced diameter hole that communicates with the countersunk hole. The reduced diameter hole passes through the side wall of the depth ring and the hook positioning mechanism and communicates with the positioning groove of the depth ring.
[0011] Preferably, the front end of the insertion mechanism is provided with a semi-circular observation port to enable visual inspection.
[0012] Preferably, the ejector pin has a conical boss at its front end, which is adapted to the locating pin to be assembled. Preferably, the slide of the locating pin insertion type propulsion mechanism has an open structure, and the ejector pin inside the slide is driven to connect with the pressure rod, which facilitates effective connection between the ejector pin and the pressure rod.
[0013] Preferably, the stroke control mechanism is also provided with a pressure rod boss that cooperates with the pressure rod. The pressure rod boss is used to reduce the friction between the pressure rod and the structural components during the assembly process.
[0014] As a preferred embodiment, the cylindrical boss is also provided with a rear circular hole on its circumference. The rear circular hole is connected to the pressure rod through a cylindrical pin, so that the positioning pin is subjected to uniform force when it is pushed forward stably.
[0015] Preferably, the cross-section of the movable cavity is oval-shaped, which allows for limiting and controlling the depth of the positioning pin installation, ensuring consistent positioning pin installation.
[0016] Preferably, the depth ring and hook positioning mechanism are also provided with an installation and removal expansion groove, which is similar in shape to a semi-circle. The installation and removal expansion groove is located outside the positioning groove of the depth ring and communicates with the positioning groove of the depth ring.
[0017] Furthermore, the depth-fixing ring and hook positioning mechanism are also provided with a base fixing hole, a stroke control mechanism connection hole, and a fulcrum connection hole that cooperates with the connecting rod.
[0018] The present invention also provides a method for using the aforementioned quick-installation device for insertable positioning pins, comprising the following steps:
[0019] Step 1: Prepare the depth ring, hook, and positioning pin;
[0020] Step 2: Retract the pressure rods of the mounting device to both sides;
[0021] Step 3: Place the depth ring and hook to be installed into the positioning structure of the depth ring and hook in sequence;
[0022] Step 4: Insert the positioning pin into the second inlet.
[0023] Step 5: Push the two pressure bars towards the center until they are in place;
[0024] Step 6: Move the pressure rod of the installation device to the limit position on both sides;
[0025] Step 7: Remove the assembled depth-fixing component from the mounting and unmounting expansion slot in the depth-fixing ring and hook positioning structure;
[0026] Step 8: Complete the assembly process.
[0027] Compared with the prior art, the beneficial effects of the present invention are: through this installation device, the positioning of the depth ring and hook, the centering and insertion of the positioning pin, the stroke control, and the lever function are realized. The assembly time of each depth component is shortened from the original 2-3 minutes to an average of 15 seconds, which greatly improves the assembly efficiency, reduces the intensity of manual labor, and improves the consistency of quality. In addition, the device has a reasonable structure and is easy to operate. Attached Figure Description

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:
[0034] like Figure 1-5 As shown, a quick-installation device for an insertable positioning pin is provided. The installation device mainly includes a depth-fixing ring and hook positioning mechanism 100, a positioning pin insertable propulsion mechanism 200, a lever mechanism 400, and a stroke control mechanism 300. Figure 1 This is a schematic diagram of the overall structure in use.
[0035] like Figure 2 As shown, the depth ring and hook positioning mechanism 100 is installed at the center of the installation device. The depth ring and hook positioning mechanism 100 has a depth ring positioning groove 110, a hook positioning post 120, and a limiting hole 160. The depth ring positioning groove 110 and the hook positioning post 120 are adapted to the dimensions of the depth ring 10 and hook 20 to be assembled and can position them. The limiting hole is coaxially arranged with the pin holes of the depth ring 10 and hook 20 respectively placed on the depth ring positioning groove 110 and hook positioning post 120. In other words, the depth ring positioning groove 110 and hook positioning post 120 fit the dimensions of the depth-fixing component, determined according to the dimensions of the depth ring 10 and the installation position of the hook 20, so that the positions of the depth ring 10 and hook 20 to be assembled are relatively fixed, achieving the function of concentric installation pin holes, thus replacing manual intervention and adjustment during the assembly process.
[0036] like Figure 3As shown, the positioning pin insertion type propulsion mechanism 200 includes a fixed-depth insertion structure 210 adapted to the installation dimensions of the fixed-depth ring and the hook, a movable cavity 220, and a pin 230 installed inside the movable cavity 220. The fixed-depth insertion structure 210 has an insertion mechanism 211 axially positioned at its front end and a connecting end 214 axially positioned at its rear end. The insertion mechanism 211 and the fixed-depth insertion structure 210 each have an inner cavity through which the positioning pin to be assembled passes, and their inner cavities are interconnected. The fixed-depth insertion structure 210 also has a first pin inlet 212 opening upwards at 90°, which communicates with the inner cavity of the fixed-depth insertion structure 210. The connecting end 214 is connected to the front end of the movable cavity 220. The connector 214 is connected to the movable cavity 220 to allow the positioning pin to fall naturally into place. A spring 240 is sleeved on the ejector pin 230. The rear end of the ejector pin 230 has a cylindrical boss 232 that mates with the spring 240. The outer diameter of the cylindrical boss 232 is smaller than the inner diameter of the movable cavity 220. When the fixed depth insertion component 210 is pushed into the fixed depth ring mounting pin hole, the front end of the spring 240 abuts against the limiting hole 160 to limit the insertion. That is, the function of the spring 240 is to first push the fixed depth insertion component 210 into the fixed depth ring mounting pin hole when the lever mechanism 400 is pushed horizontally. After contacting the limiting hole, the spring 240 stops moving forward. The horizontal thrust then pushes the ejector pin 230 together with the positioning pin into the mounting pin hole, so that the hooks on both sides can be installed in one step.
[0037] like Figure 5 As shown, there are two lever mechanisms 400, which are respectively located on both sides of the installation device. Each lever mechanism 400 consists of a connecting rod 410 and a pressure rod 420. The connecting rod 410 is connected to the depth ring and the hook positioning mechanism 100, and the pressure rod 420 is connected to the positioning pin insertion type propulsion mechanism 200. The pressure rod 420 achieves horizontal concentric thrust through the connecting rod 410.
[0038] travel control mechanism such as Figure 4 As shown, there are two stroke control mechanisms 300, fixed on both sides of the mounting device. Each stroke control mechanism 300 has a second inlet 310 adapted to the first inlet 212, and a slide chamber 320 for the positioning pin insertion type propulsion mechanism 200 to slide in. The positioning pin insertion type propulsion mechanism 200 is disposed in and slidably engages with the slide chamber 320. The positioning pin insertion type propulsion mechanism 200 is driven by a pressure rod 420. The stroke control mechanism 300 also has a pressure rod stroke limiting part 330 that cooperates with the lever mechanism 400. The pressure rod stroke limiting part 330 is used to control the working stroke of the positioning pin insertion type propulsion mechanism 200. In this embodiment, the pressure rod stroke limiting part 330 is a groove structure, and stroke control is achieved through the groove sidewalls on the left and right sides of the groove.
[0039] In one embodiment, the limiting hole 160 is a stepped hole, which includes a countersunk hole at the outer end that is adapted to the outer diameter of the spring 240, and a reduced diameter hole that communicates with the countersunk hole. The reduced diameter hole passes through the side wall of the depth ring and the hook positioning mechanism 100 and communicates with the positioning groove 110 of the depth ring.
[0040] As one implementation, the front end face of the insertion mechanism 211 is provided with a semi-circular observation port 213, enabling visual inspection.
[0041] In this embodiment, the front end of the ejector pin 230 has a conical boss 231, which is adapted to the positioning pin to be assembled, making it easy to push the positioning pin forward.
[0042] In another implementation, the slide 320 has an open structure, and the ejector pin 230 inside the slide 320 is driven to connect with the pressure rod 420.
[0043] As another implementation, the stroke control mechanism 300 is also provided with a pressure rod boss 340 that cooperates with the pressure rod 420. The pressure rod boss 340 is used to reduce the friction between the pressure rod and the structural component during the assembly process.
[0044] As another implementation, the cylindrical boss 232 is also provided with a rear end circular hole 233 on its circumference. The rear end circular hole 233 is connected to the pressure rod 420 through a cylindrical pin, so that the positioning pin is subjected to uniform force when it is pushed forward stably.
[0045] In this embodiment, the cross-section of the movable cavity 220 is shaped like an oblong hole 221. This design allows for limiting and controlling the insertion depth of the locating pin, ensuring consistent installation of the locating pin.
[0046] In addition, the depth ring and hook positioning mechanism 100 is also provided with an installation and removal expansion groove 130, which is similar in shape to a semi-circle. The installation and removal expansion groove 130 is located outside the depth ring positioning groove 110 and communicates with the depth ring positioning groove 110.
[0047] Furthermore, the depth-fixing ring and hook positioning mechanism 100 are also provided with a base fixing hole 140, a stroke control mechanism 300 connection hole 170, and a fulcrum connection hole 150 that movably cooperates with the connecting rod 410.
[0048] The method of using the above-mentioned quick-installation device for insert-type positioning pins includes the following steps:
[0049] Step 1: Prepare a depth-fixing ring 10, a line hook 20, and a positioning pin;
[0050] Step 2: Retract the pressure rod 420 of the mounting device to both sides;
[0051] Step 3: Place the depth-fixing ring 10 and the line hook 20 to be installed into the depth-fixing ring and line hook positioning mechanism 100 in sequence;
[0052] Step 4: Insert the positioning pin into the second inlet 310;
[0053] Step 5: Push the two pressure rods 420 towards the center into place;
[0054] Step 6: Move the pressure rod 420 of the installation device to the limit position on both sides;
[0055] Step 7: Remove the assembled depth-fixing component from the mounting and unmounting expansion slot 130 in the depth-fixing ring and hook positioning mechanism 100;
[0056] Step 8: Complete the assembly process.
[0057] This invention, through positioning with a depth-fixing ring and hook, centering and advancing with a positioning pin, stroke control, and lever function, ultimately reduces the assembly time of each depth-fixing component from the original 2-3 minutes to an average of 15 seconds, increasing efficiency by more than 8 times. This device significantly improves assembly efficiency, reduces manual labor intensity, and enhances quality consistency. Furthermore, the device is highly versatile.
[0058] The above description only illustrates preferred embodiments of the present invention and should not be construed as limiting the scope of the claims. Any equivalent structural or procedural modifications made using this specification are included within the patent protection scope of the present invention.
