[0002] A bathtub is a device for people to bathe. Therefore, for those who like to take a bath, their homes are generally equipped with a bathtub. The faucet is an indispensable component of the bathtub. The faucet shell is usually cast. After the shell is formed, its holes need to be further punched and corrected to achieve a round hole structure that meets the regulations.

However, this method is often inefficient, and there are often excess materials and burrs on the inner wall of the hole of the shell after casting. During the punching correction, these burr excesses may affect the roundness of the hole after correction.

[0023] The following describes the embodiments of the present invention with reference to the accompanying drawings. In the process, to ensure clarity and convenience of the description, we may exaggerate the width of the lines or the size of the components in the drawings.

[0024] In addition, the following terms are defined based on the functions of the present invention and may vary depending on the intention or custom of the user or operator. Therefore, these terms are defined based on the entire content of this specification.

[0025] like Figures 1 to 5 As shown, a bathtub faucet shell punching device includes a storage base 1, a positioning assembly 2 is installed in the middle of the rear end of the storage base 1, and the lower end of the shell is internally supported by the positioning assembly 2. A driving assembly 3 used in conjunction with the positioning assembly 2 is evenly installed on the storage base 1, and a punching and tapping assembly 4 is slidably provided on the driving assembly 3. The punching and tapping assembly 4 collects the waste generated by the punching and tapping of the shell and transports it to the inner cavity of the storage base 1.

[0026] During the actual operation, the shell is placed on the positioning component 2, and then the positioning component 2 is structurally adjusted to support and position the lower end of the shell, and the driving component 3 used in conjunction with the positioning component 2 drives the punching and tapping components 4 to move collectively toward the middle to perform aligned inner hole grinding and outer wall tapping operations on the interfaces around the shell.

[0027] Reference Figure 3 As shown, the positioning assembly 2 includes an intermediate column 21, which is installed on the storage base 1. A connecting column 22 is coaxially installed on the upper end of the intermediate column 21, and a positioning unit 23 is provided on the connecting column 22. A connecting sleeve 24 used in conjunction with the positioning unit 23 is provided on the horizontal electric turntable, and the horizontal electric turntable is installed on the outer wall of the intermediate column 21. The outer sleeve of the connecting sleeve 24 is installed with a main bevel gear 25.

[0028] Reference Figure 3As shown, the positioning unit 23 includes a threaded sleeve 231, which is slidably arranged on the connecting column 22 up and down, and the threaded sleeve 231 and the connecting sleeve 24 are threadedly connected. The upper end of the threaded sleeve 231 is provided with an extrusion head 232, and a positioning piece 233 used in conjunction with the extrusion head 232 is horizontally slidably arranged in a hidden groove 234 opened on the side wall of the connecting column 22, and the positioning piece 233 and the hidden groove 234 are elastically connected; the lower end of the positioning piece 233 is provided with a guide groove, which is composed of an extrusion groove and a linear groove, and the linear groove and the extrusion groove are connected to each other up and down. The inclined surface of the extrusion groove is a structure that gradually tilts inward from bottom to top, which reduces the difficulty of extrusion, and the guide groove corresponds to the position of the extrusion head 232. When the extrusion head 232 contacts the extrusion groove, the positioning member 233 is squeezed outward. When the upper end of the extrusion head 232 enters the linear groove, the positioning member 233 is fully extended. The horizontal position of the subsequent positioning member 233 remains stationary, but the connecting sleeve 24 will continue to rotate to ensure that the punching and tapping assembly 4 enters the interface of the shell side wall for grinding and tapping (at this time, the extrusion head 232 continues to rise and is inserted into the linear groove).

[0029] During actual operation, the lower end of the shell is inserted into the connecting column 22, and the connecting sleeve 24 is driven to rotate by the horizontal electric turntable. Under the threaded cooperation between the connecting sleeve 24 and the threaded sleeve 231, the threaded sleeve 231 is in an upward movement, and the synchronously rising extrusion head 232 extrude the guide groove so that the positioning piece 233 extends as a whole and is stuck in the inner wall of the lower end of the shell to position the shell.

[0030] Reference Figure 2 As shown, the driving assembly 3 includes a mounting frame 31, which is mounted on the storage base 1. A lead screw 32 is rotatably arranged between the mounting frame 31, and a sliding block 33 is arranged on the lead screw 32. Due to the different pitches of the lead screw 32 and the threaded sleeve 231, the rising height of the connecting sleeve 24 and the sliding distance of the sliding block 33 are different. The lower end of the sliding block 33 is slidably arranged in a sliding groove opened in the storage base 1, and a driven bevel gear 34 is installed at the inner end of the lead screw 32, which is meshed with the main bevel gear 25.

[0031] During actual operation, the rotating connecting sleeve 24 drives the main bevel gear 25 to rotate, and according to the engagement of the main bevel gear 25 and the driven bevel gear 34, the lead screw 32 is driven to rotate forward and reverse, thereby driving the sliding block 33 to move inward or outward.

[0032] Reference Figure 2As shown, the punching and tapping assembly 4 includes a connecting frame 41, which is installed on the sliding block 33. A connecting pipe 42 is connected between the connecting frame 41 and the inner cavity of the storage base 1. An electric rotating part 43 is provided inside the connecting frame 41, and a punching and tapping head 44 is installed inside the electric rotating part 43; the middle part of the connecting pipe 42 is a retractable flexible pipe structure, the lower half of the connecting pipe 42 is connected to the air pump 45, and the air pump 45 is installed on the storage base 1, and the waste generated by grinding is sucked into the connecting frame 41 by the air pump 45 and then transported from the connecting pipe 42 to the inner cavity of the storage base 1.

[0033] Reference Figure 2 、 Figure 4 As shown, the punching and tapping head 44 includes a punching and grinding sleeve 441 and a tapping sleeve 442. The punching and grinding sleeve 441 is detachably connected to the electric rotary part 43, and the tapping sleeve 442 is coaxially installed on the outside of the punching and grinding sleeve 441. The outer surface of the punching and grinding sleeve 441 is paved with a grinding layer, and the front half of the punching and grinding sleeve 441 is evenly provided with a leakage groove 1 along its circumference, and the middle part of the punching and grinding sleeve 441 is evenly provided with a leakage groove 2 along its circumference, and the leakage groove 1 and the leakage groove 2 arranged on the left and right are arranged in a staggered manner in a ring. The opening of the leakage groove 1 and the leakage groove 2 serves as the channel entrance for the polished waste to enter the connecting frame 41.

[0034] During the actual operation process, when the punching and tapping assembly 4 is about to approach the shell side wall interface, the electric rotary member 43 drives the punching and tapping head 44 to rotate at high speed. When the punching and tapping head 44 contacts the interface, the punching and tapping head 44 is polished on the inner wall of the interface hole by the punching and polishing sleeve 441 to polish the burrs, and the tapping sleeve 442 is used to tap the outer wall of the interface.

[0035] In addition, it should be understood that although this specification is described in terms of implementation methods, not every implementation method contains only one independent technical solution. This narrative method of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other implementation methods that can be understood by those skilled in the art.
