Description

Technical Field

[0001] This invention relates to the field of pipe manufacturing and processing equipment, and in particular to a pressure plate pin mounting device and its usage method. Background Technology

[0002] Currently, in the pipe fitting processing flow, some pipes require the installation of pins. The traditional method of pressing in pins mainly relies on manual operation. After the operator places the pin, they gently hammer it in with a hammer, and the depth of hammering depends on the operator's experience. This method is inefficient, the depth of hammering is difficult to control, and it is also easy to injure one's hand.

[0003] There are also some semi-automatic pin pressing devices on the market. The pins are manually placed into the tooling fixture and then automatically pressed into the pressure plate. However, these devices are still based on manual labor and cannot improve processing efficiency.

[0004] Meanwhile, due to the high degree of manual involvement in current press-fit pin equipment, it is difficult to automate the equipment in the preceding and following processes, further reducing the overall processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a pressure plate pin-installing device and its method of use that improves the efficiency of pin installation and ensures the depth of pin installation.

[0006] To solve the above-mentioned technical problems, the present invention provides a pressure plate pin mounting device, including a base, a contour clamping mold disposed on one side of the base, and a guide assembly disposed on the base. The guide assembly includes an upper cavity and a lower cavity, forming a guide channel between the upper cavity and the lower cavity. The pin is placed in the guide channel. The contour clamping mold is used to clamp the workpiece, and one end of the guide channel faces the pin hole of the workpiece. A ejector pin is mounted on one side of the guide assembly. The ejector pin can move along the guide channel to push the pin. The device also includes a material platform and a liftable lifting platform disposed on the material platform. A material clamping mold is movably connected to one side of the lifting platform. The material clamping mold is used to clamp the end of the workpiece away from the contour clamping mold, so that the material clamping mold drives the workpiece to detach from the contour clamping mold.

[0007] Furthermore, a guide rail is provided on the base, and the lower cavity is movably mounted on the guide rail so that when the pin is pushed to the pin hole of the workpiece, the sides of the lower cavity and the upper cavity abut against the copying clamping mold.

[0008] Furthermore, the ejector pin is connected to the ejector pin seat, and a limiting seat matching the ejector pin seat is movably provided on one side of the lower cavity. A compression spring is connected between the lower cavity and the copying mold. When the lower cavity abuts against the copying mold, the compression spring extends.

[0009] Furthermore, a second material detection element is provided on the side of the upper cavity near the guide channel. When the second material detection element detects the pin, the ejector pin moves.

[0010] Furthermore, a feeding channel is provided on one side of the base, and a feeding port is opened at the top of the upper cavity. The feeding port is connected to the guide channel, and the discharge port at one end of the feeding channel matches the feeding port.

[0011] Furthermore, a linear track is provided on one side of the lifting platform, the material clamping mold is connected to the movable seat, and the movable seat and the linear track are in movable cooperation.

[0012] Furthermore, a moving rod is provided on the side of the moving seat away from the workpiece, and a drive rod is rotatably mounted on the side of the material platform. The drive rod is located above the moving rod, and both the drive rod and the moving rod have threads on their outer circumferences so that the moving rod and the drive rod are threaded together when they come into contact.

[0013] Furthermore, the cross-section of the inner hole of the material clamping mold is stepped.

[0014] Furthermore, a pad is provided on one side of the lower part of the drive rod, and the pad matches the end of the moving rod.

[0015] The present invention also discloses a method of using a pressure plate pin mounting device, which includes the following steps:

[0016] Step 1: Place the workpiece in the material clamping mold, and move the workpiece to the contour clamping mold for fixing by the movement of the material clamping mold and the lifting platform.

[0017] Step 2: Load the pins into the guide channel;

[0018] Step 3: Push the pin with the top pin so that the pin moves along the guide channel to the pin hole of the workpiece, and then press the pin in place.

[0019] Step 4: The ejector pin retracts, the copying mold releases the workpiece, and the workpiece is unloaded by the movement of the material clamping mold and the lifting platform.

[0020] The beneficial effects of this invention are that, during the pin pressing process, the workpiece is placed in a conformal mold for fixation, and the pin is placed in a guide channel with the end of the pin facing the pin hole of the workpiece. Then, the ejector pin moves along the guide channel and pushes one end of the pin during the movement, so that the ejector pin presses the pin into the pin hole to complete the pin pressing process. In this process, no manual assistance is required, which can improve the overall processing efficiency. At the same time, since the movement stroke of the ejector pin is controllable, the pressing depth of the pin can also be accurately controlled.

[0021] Meanwhile, the lifting platform and material clamping mold are designed to coordinate the lifting of the lifting platform and the movement of the material clamping mold, thereby allowing the workpiece to be lifted and moved accordingly. This ensures that the workpiece can be automatically and stably loaded or unloaded to the conforming clamping mold, eliminating the need for manual intervention in the loading and unloading of pins and workpieces. This allows the equipment of the preceding and following processes to be integrated into the pin pressing equipment of this solution, greatly improving the efficiency of the overall processing.

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention are within the scope of protection of the present invention.

[0030] Those skilled in the art should understand that, in the disclosure of this invention, the terms "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limiting this invention.

[0031] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number.

[0032] like Figure 1-6 The present invention provides a pin-loading device for a pressure plate, comprising a base 1, a contour clamping mold 2 disposed on one side of the base 1, and a guide assembly disposed on the base 1. The guide assembly includes an upper cavity 3 and a lower cavity 4, forming a guide channel 5 between the upper cavity 3 and the lower cavity 4. The pin 6 is placed in the guide channel 5. The contour clamping mold 2 is used to clamp the workpiece 7, and one end of the guide channel 5 faces the pin hole of the workpiece 7. A ejector pin 8 is mounted on one side of the guide assembly. The ejector pin 8 can move along the guide channel 5 to push the pin 6. The device also includes a material platform 21 and a liftable lifting platform 22 disposed on the material platform 21. A material clamping mold 23 is movably connected to one side of the lifting platform 22, and the material clamping mold 23 is used to clamp the end of the workpiece 7 away from the contour clamping mold 2, so that the material clamping mold 23 can drive the workpiece 7 to detach from the contour clamping mold 2.

[0033] When pressing pins, the workpiece is placed in a mold for fixation, and the pin is placed in a guide channel with the end of the pin facing the pin hole of the workpiece. Then, the ejector pin moves along the guide channel and pushes one end of the pin during the movement, so that the ejector pin presses the pin into the pin hole to complete the pin pressing process. No manual assistance is required in this process, which can improve the overall processing efficiency. At the same time, since the movement stroke of the ejector pin is controllable, the pressing depth of the pin can also be accurately controlled.

[0034] Meanwhile, the lifting platform and material clamping mold are designed to coordinate the lifting of the lifting platform and the movement of the material clamping mold, thereby allowing the workpiece to be lifted and moved accordingly. This ensures that the workpiece can be automatically and stably loaded or unloaded to the conforming clamping mold, eliminating the need for manual intervention in the loading and unloading of pins and workpieces. This allows the equipment of the preceding and following processes to be integrated into the pin pressing equipment of this solution, greatly improving the efficiency of the overall processing.

[0035] The contour clamping mold adopts a double-clamping mold structure on both sides. The two clamping molds are controlled by a cylinder to move closer or further apart, thereby clamping and fixing the workpiece. The material platform has a built-in cylinder, which controls the lifting of the lifting platform. The material clamping mold adopts a double-clamping mold structure on both sides. The two clamping molds are controlled by a cylinder to move closer or further apart, thereby clamping and fixing the end of the workpiece.

[0036] In one embodiment of this solution, a robotic arm can be used to load the workpiece onto the material clamping mold or unload it from the material clamping mold, thus avoiding the situation where the gripping space of the contouring mold is too small, making it difficult for the robotic arm to reach into the contouring mold.

[0037] It is worth mentioning that the workpiece 7 processed in this solution is a tube 71 with a pressure plate 72 sleeved on it. The pressure plate 72 has a pin hole. In this solution, the pin 6 is pressed into the pin hole.

[0038] In one embodiment of this solution, the upper cavity and the lower cavity are fixedly connected.

[0039] Preferably, a guide rail 9 is provided on the base 1, and the lower cavity 4 is movably mounted on the guide rail 9 so that when the pin 6 is pushed to the pin hole of the workpiece 7, the lower cavity 4 and the side of the upper cavity 3 abut against the contour clamping mold 2.

[0040] Specifically, when pushing the pin, the upper and lower cavities first move along the guide rail, so that the guide channel is close to the copying mold, and the sides of the upper and lower cavities abut against the copying mold, so as to prevent the pin from falling out of the gap between the guide channel and the copying mold, and at the same time ensure the stability of the relative position of the upper and lower cavities and the copying mold during the processing.

[0041] Preferably, the ejector pin 8 is connected to the ejector pin seat 10, and a limiting seat 11 matching the ejector pin seat 10 is movably provided on one side of the lower cavity 4. A compression spring 12 is connected between the lower cavity 4 and the contouring mold 2. When the lower cavity 4 abuts against the contouring mold 2, the compression spring 12 extends.

[0042] Specifically, when the push pin needs to be ejected, the ejector seat moves closer to the workpiece and drives the ejector pin to move along the guide channel. At the same time, the clamping spring is adjusted from the compressed state to the extended state. During this process, the clamping spring drives the lower cavity to move closer to the mold clamping position. Then, after the clamping spring is fully extended, the lower cavity abuts against the mold clamping position. At this time, the ejector seat continues to drive the ejector pin to push. After the pin is pressed in, the ejector seat resets and drives the limit seat and the lower cavity to reset and move, causing the clamping spring to retract, so as to ensure that the lower cavity can be moved by the clamping spring in the future.

[0043] The ejector pin seat is moved by a cylinder.

[0044] It is worth mentioning that a guide rod 20 is provided on the side of the mold close to the lower cavity. The guide rod 20 passes through the lower cavity 4, and one end of the compression spring 12 is connected to the end of the guide rod 20 away from the mold 2. The other end of the compression spring 12 is connected to the lower cavity 4, so that when the compression spring extends, it can drive the lower cavity to move closer to the mold. When the lower cavity moves away from the mold, the compression spring retracts.

[0045] In one embodiment of this solution, a pull block is provided on the ejector pin or ejector pin seat. When the ejector pin seat and ejector pin are reset by the pull block, the pull block pulls the limiting seat to move away from the mold-forming clamping die, thereby compressing the clamping spring. It is worth mentioning that when the ejector pin pushes the pin to the workpiece, there is a certain gap between the pull block and the limiting seat. This ensures that during the initial stroke of the ejector pin seat and ejector pin reset, the pull block does not pull the limiting seat to reset. At the same time, it ensures that after the lower cavity abuts against the mold-forming clamping die, the ejector pin seat and ejector pin will continue to have a certain gap at one end, so as to make room for the gap between the pull block and the limiting seat, and to ensure that the ejector pin can move and push while the lower cavity is stationary.

[0046] In other words, the movement of the lower cavity in this scheme is as follows: the compression spring is in a compressed state, the ejector pin seat and the lower cavity maintain the initial position → the ejector pin seat moves towards the mold clamping position, and the compression spring simultaneously pushes the lower cavity towards the mold clamping position (during this process, the pull block maintains contact with the limit seat) → the compression spring is fully extended, the lower cavity abuts against the mold clamping position, and the ejector pin seat drives the ejector pin to move and push → after the pushing is completed, the ejector pin seat returns to a certain distance, the pull block contacts the limit seat and pulls the lower cavity to return to its original position, and the compression spring retracts.

[0047] In one embodiment of this solution, the limiting seat 11 has a corner structure 14, and the corner structure 14 corresponds to the outer edge of the lower cavity 4.

[0048] Preferably, a second material detection element 13 is provided inside the upper cavity 3 on the side near the guide channel 5. When the second material detection element 13 detects the pin 6, the ejector pin 8 moves.

[0049] Specifically, the second material detection component is used to check whether the pin is located in the guide channel to ensure the stability of the pin's push.

[0050] The second material detection component uses an infrared detection component.

[0051] Preferably, a feeding channel 15 is provided on one side of the base 1, and a feeding port 16 is provided on the top of the upper cavity 3. The feeding port 16 is connected to the guide channel 5, and the discharge port 17 at one end of the feeding channel 15 matches the feeding port 16.

[0052] Specifically, when the pin is fed into the guide channel, the pin moves along the feeding channel and falls from the drop port into the feed port, and then enters the guide channel from the feed port, ensuring the stability and accuracy of the pin feeding.

[0053] In one embodiment of this solution, a vibratory feeder is connected to the end of the feeding channel away from the guide channel, and the vibratory feeder sequentially transports each pin into the feeding channel.

[0054] Preferably, the feeding channel 15 has a first material detection element 18 built in, and the feeding channel 15 has a feeding cylinder 19 on the side away from the upper cavity 3. When the first material detection element 18 detects the pin 6, the feeding cylinder 19 pushes the pin 6 in the feeding channel 15.

[0055] Specifically, the first material detection component is used to detect the pins in the feeding channel to ensure that the feeding cylinder pushes the pins in the feeding channel stably and accurately.

[0056] It is worth mentioning that in this solution, the feeding cylinder can only be activated to push the material after the upper cavity has been reset to its initial position along with the lower cavity, so as to ensure the matching of the feeding port and the discharge port.

[0057] The first material detection component uses an infrared detection component.

[0058] Preferably, a linear track 24 is provided on one side of the lifting platform 22, the material clamping mold 23 is connected to the movable seat 25, and the movable seat 25 and the linear track 24 are in movable cooperation.

[0059] Specifically, when the pin is pressed into the workpiece, the material clamping mold always keeps the end of the workpiece fixed. Then, when it is necessary to unload the workpiece, the copying mold releases the workpiece, and then the lifting platform lifts the workpiece to get off the copying mold. After the lifting platform rises to the specified stroke, the moving seat moves along the straight track to a position away from the copying mold, so that the workpiece can be completely removed from the position of the copying mold and leave enough gripping space for the robot arm.

[0060] Preferably, a moving rod 26 is provided on the side of the movable seat 25 away from the workpiece 7, and a drive rod 27 is rotatably mounted on one side of the material platform 21. The drive rod 27 is located above the moving rod 26, and both the drive rod 27 and the moving rod 26 have threads on their outer circumferences so that the moving rod 26 and the drive rod 27 are threaded together when they come into contact.

[0061] Specifically, after the lifting platform raises the movable seat to the specified stroke, the moving rod contacts the drive rod. At this time, the drive rod rotates and drives the moving rod to move through the threaded engagement, so that the movable seat moves along the linear track to ensure the stability of the movable seat during the movement process.

[0062] The material platform has a built-in servo motor, which controls the rotation of the drive rod.

[0063] Preferably, the inner cross-section of the material clamping mold 23 is stepped, so that the material clamping mold can adapt to workpieces of different pipe diameters.

[0064] Preferably, a pad 28 is provided on one side of the lower part of the drive rod 27, and the pad 28 matches the end of the moving rod 26.

[0065] Specifically, when the drive rod moves the moving rod, a pad can be used to limit the end of the moving rod to prevent the end of the moving rod from colliding with the material platform.

[0066] The pad is made of rubber.

[0067] The present invention also discloses a method of using a pressure plate pin mounting device, which includes the following steps:

[0068] Step 1: Place the workpiece 7 at the material clamping mold 23. Through the moving cooperation between the material clamping mold 23 and the lifting platform 22, move the workpiece 7 to the contour clamping mold 2 for fixing.

[0069] Step 2: Load pin 6 into guide channel 5;

[0070] Step 3: The ejector pin 8 pushes the pin 6 so that the pin 6 moves along the guide channel 5 to the pin hole of the workpiece 7, and then the pin 6 is pressed in.

[0071] Step 4: The ejector pin 8 retracts, the contour clamping mold 2 releases the workpiece 7, and the workpiece 7 is unloaded through the moving cooperation of the material clamping mold 23 and the lifting platform 22.

[0072] This invention is not limited to the preferred embodiments described above. Anyone can derive other products in various forms under the guidance of this invention. However, regardless of any changes in shape or structure, any technical solution that is the same as or similar to this application falls within the protection scope of this invention.
