[0002] Hole enlargement is mainly used to enlarge holes with pre-cast holes or bottom holes in order to improve the dimensional accuracy and positional accuracy of the holes and reduce surface roughness.

[0003] By using different tools to enlarge holes, products can have multiple hole sizes based on the original holes, allowing them to be used under different requirements. Traditional hole enlargement methods generally involve manually adjusting the hole diameter using tools. However, since the enlargement tools themselves are large and heavy, they can put a heavy burden on workers, making it difficult to use them for extended periods and affecting their efficiency and ease of use over long periods.

[0004] Therefore, we provide a quick-release faucet hole enlarging device. Utility Model Content

[0005] The purpose of this utility model is to address the aforementioned technical problems by providing a quick-release faucet hole-expanding device that achieves the effect of rapid and efficient hole expansion through product movement.

[0006] In view of this, the present invention provides a quick-release faucet hole-expanding device, including a processing table and a cylinder installed above the processing table. A threaded cylinder is installed at the output end of the cylinder. A connecting screw head is threadedly connected to the inner wall of the threaded cylinder. A connecting rod is fixedly connected to the end of the connecting screw head away from the threaded cylinder. A connecting rod is threadedly connected to the inner wall of the end of the connecting rod away from the connecting screw head. A punch is installed at the outer end of the connecting rod. An expanding head is inserted into the punch. The expanding head passes through a limiting plate. The limiting plate is installed on the upper surface of the processing table, and the punch passes through the limiting plate.

[0007] Preferably, a control switch is provided at the center of the lower part of the processing table, and the control switch is used to control the operation of the cylinder.

[0008] Preferably, a plurality of anti-slip strips are installed on the middle of the outer surface of the connecting rod, and the anti-slip strips are distributed perpendicular to the rotation direction of the connecting rod.

[0009] Preferably, the punch rod is provided with a guide ring, and the punch rod extends out of the outer end of the guide ring and is provided with a retaining ring. The retaining ring and the guide ring are integral structures, and the size of the guide ring is smaller than the size of the retaining ring.

[0010] Preferably, the retaining ring has a retaining groove on the side near the limiting plate, the expanding head is inserted into the retaining groove, and a fastening bolt is provided through one side of the retaining ring, the fastening bolt being threadedly connected to the limiting plate.

[0011] Preferably, a guide groove is provided through the limiting plate, and an auxiliary groove is provided on the side of the limiting plate near the retaining ring. The auxiliary groove is larger than the guide groove, and the auxiliary groove and the guide groove are concentric circles.

[0012] Preferably, the outer half of the expanding head is inserted into the auxiliary groove, the front half of the expanding head penetrates the guide groove, the punch penetrates the expanding head, and the specifications of the punch are slightly larger than the specifications of the inner wall of the front half of the expanding head.

[0013] Compared with the prior art, this utility model provides a quick-release faucet hole-expanding device, which has the following beneficial effects:

[0014] 1. This utility model, driven by a cylinder and connected by a threaded cylinder, connecting screw head, connecting rod, and connecting screw rod, causes the punch rod to move back and forth in the horizontal direction. Under the positioning of the expanding head by the limiting plate, the punch rod punches out from the inside of the expanding head, causing the product sleeved on the outside of the expanding head to deform and expand due to the impact of the punch rod. This causes the product sleeved on the outside to expand synchronously, thereby forming the effect of expanding the hole in the product.

[0015] 2. This utility model, supported by the reciprocating drive of a cylinder, allows the device to reset after the hole enlargement is completed, relieving the pressure on the enlarger head and allowing it to automatically reset, facilitating the removal of the product. Before the next movement stroke, the next product is placed on the outside of the enlarger head to form the next hole enlargement operation. This allows the operator to simply move the product and control the hole enlargement device to perform the hole enlargement operation, ultimately making the device simple in structure and highly efficient in its operating stroke.

[0016] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "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 utility model 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, they should not be construed as limitations on this utility model.

[0024] Example 1: A quick-release faucet hole-expanding device, such as... Figure 1 - Figure 4 As shown, the machine includes a processing table 1 and a cylinder 2 installed on the upper part of the processing table 1. A threaded cylinder 4 is installed at the output end of the cylinder 2. A connecting screw head 6 is threadedly connected to the inner wall of the threaded cylinder 4. A connecting rod 5 is fixedly connected to the end of the connecting screw head 6 away from the threaded cylinder 4. A connecting screw rod 701 is threadedly connected to the inner wall of the end of the connecting rod 5 away from the connecting screw head 6. A punch rod 7 is installed at the outer end of the connecting screw rod 701. An expansion head 13 is inserted into the punch rod 7. The expansion head 13 passes through a limit plate 12. The limit plate 12 is installed on the upper surface of the processing table 1, and the punch rod 7 passes through the limit plate 12.

[0025] Driven by cylinder 2 and connected by threaded cylinder 4, connecting screw head 6, connecting rod 5, and connecting screw 701, punch 7 is driven to move back and forth horizontally. With the positioning of the expanding head 13 by the limiting plate 12, punch 7 punches out from inside the expanding head 13. The product fitted on the outside of the expanding head 13 is deformed and expanded by the impact of punch 7, causing the expanding head 13 to expand synchronously, thus creating a hole-expanding effect on the product. This allows the device to quickly expand the hole of the product. With the reciprocating drive support of cylinder 2, the device resets after the hole-expanding is completed, relieving the pressure on the expanding head 13 and allowing it to automatically reset, facilitating the removal of the product. Before the next movement stroke, the next product is fitted on the outside of the expanding head 13 to form the next hole-expanding operation. The operator only needs to move the product and control the hole-expanding device to perform the hole-expanding operation. Ultimately, the device has the effect of simple structure and efficient use of the operating stroke.

[0026] like Figure 1 - Figure 4 As shown, a control switch 3 is installed in the middle of the lower part of the processing table 1. The control switch 3 is used to control the operation of the cylinder 2.

[0027] By placing the control switch 3 at the bottom of the device, operators can control the cylinder 2 by stepping on it, which facilitates manual movement of the product and improves the convenience and efficiency of the device.

[0028] like Figure 1 - Figure 4 As shown, several anti-slip strips 8 are installed in the middle of the outer surface of the connecting rod 5, and the anti-slip strips 8 are distributed perpendicular to the rotation direction of the connecting rod 5.

[0029] By setting multiple anti-slip strips 8, the connecting rod 5 has a rotational anti-slip effect, ensuring stable and rapid rotation of the connecting rod 5.

[0030] Example 2: A quick-release faucet hole-expanding device, such as... Figure 1 - Figure 4 As shown, a guide ring 11 is provided through the punch rod 7, and a retaining ring 9 is provided through the outer end of the punch rod 7 extending from the guide ring 11. The retaining ring 9 and the guide ring 11 are an integral structure, and the size of the guide ring 11 is smaller than the size of the retaining ring 9.

[0031] The retaining ring 9 has a retaining groove 901 on the side near the limiting plate 12. The expanded head 13 is inserted into the retaining groove 901. A fastening bolt 10 is provided through one side of the retaining ring 9 and is threadedly connected to the limiting plate 12.

[0032] With the fastening bolt 10 tightened, the guide ring 11 and retaining ring 9 are positioned on one side of the limiting plate 12, providing a guiding effect for the movement of the punch 7, ensuring the accuracy of the running angle of the punch 7 during operation, and with the insertion and positioning of the expansion head 13 in the slot 901, ensuring the stability of the position of the expansion head 13 when it is used, and ensuring its high efficiency when expanding the hole.

[0033] like Figure 1 - Figure 4 As shown, a guide groove 1202 is provided through the limiting plate 12, and an auxiliary groove 1201 is provided on the side of the limiting plate 12 near the retaining ring 9. The auxiliary groove 1201 is larger than the guide groove 1202, and the auxiliary groove 1201 and the guide groove 1202 are concentric circles.

[0034] The outer half of the expanded head 13 is inserted into the auxiliary groove 1201. The front half of the expanded head 13 passes through the guide groove 1202. The punch 7 passes through the expanded head 13, and the specifications of the punch 7 are slightly larger than the specifications of the inner wall of the front half of the expanded head 13.

[0035] The combined limiting effect of the auxiliary groove 1201 further improves the positioning effect of the expansion head 13. The further limiting effect of the guide groove 1202 on the front half of the expansion head 13 stabilizes the working position of the expansion head 13. The removal of the retaining ring 9 facilitates the replacement of the expansion head 13, thereby ensuring the stability of the position of the expansion head 13 during use and the convenience of its adjustment and replacement.

[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
