DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Example 1

[0043] See also Figure 1-4A milling machine tool for faucet processing includes a bed 1, a moving platform 11 and a ram 2 are respectively installed at one end of the bed 1, a connecting frame 10 is installed at one end of the ram 2, a tool holder 4 is installed at the lower end of the connecting frame 10, a first hydraulic column 14 is installed at one end of the tool holder 4, a through groove 27 is arranged at the lower end of the tool holder 4, a second hydraulic column 13 is installed inside the tool holder 4, one end of the second hydraulic column 13 is connected to the first hydraulic column 14, a first trigger device 3 and a second trigger device 5 are respectively arranged at both ends of the tool holder 4, and the first trigger device 3 and the second trigger device 5 are used to resist the faucet.

[0044] A transmission shaft 12 is installed at the lower end of the second hydraulic column 13, and a milling cutter 15 is connected to the lower end of the transmission shaft 12. The milling cutter 15 is used to mill the end face of the faucet. The milling cutter 15 is slidably connected to the through groove 27. A friction device 7 is installed inside the milling cutter 15. The friction device 7 is used to rub the burrs on the end face of the faucet. The friction device 7 includes a round shaft rod 71 installed inside the transmission shaft 12, and a friction strip 72 is installed at the lower end of the round shaft rod 71. The lower end of the milling cutter 15 is provided with a receiving groove 75 for receiving the friction strip 72.

[0045] The processing of faucets requires sand casting, and then part of the excess material is removed by milling. The most important thing is to mill the end face of the faucet base to reach the standard size. However, since the existing faucets are all in an inverted "J" shape and are slender, when a large amount of faucet excess material is milled, the faucet will be squeezed and deformed by the milling cutter 15 or the milling cutter 15 will be worn and damaged. And because the faucet is a casting, there may be excess material at its water outlet, so it is impossible to completely mill all the excess material near the end face through a simple CNC program. In this regard, the device detects the milling cutter 15 by setting a first trigger device 3, a second trigger device 5 and a detection device 6. When excess material appears, a signal will be sent, and the first hydraulic column 14 and the second hydraulic column 13 will control the milling cutter 15 to automatically adjust its position, so as to adapt to milling under different conditions;

[0046] like Figure 1 , 2As shown in , 8-9, a fixture 17 is installed at the upper end of the mobile platform 11, and a plurality of faucets 28 are placed inside the fixture 17. The faucets 28 are clamped by the fixture 17, and then the milling cutter 15 is started to set a coordinate point for the first faucet 28 by the milling cutter 15. Then, a numerical control program is set by programming, and the fixture 17 is driven to move by the mobile platform 11, and the upper end surface of the first faucet 28 is milled by the milling cutter 15. Since there is a gap between every two faucets 28, when the milling cutter 15 mills the first faucet 28, the first trigger device 3 will slide in the gap. , and as the milling cutter 15 completes milling of the end face of the first faucet 28, its first trigger device 3 will contact the second faucet 28. When the end face height of the second faucet 28 is greater than the milling amount of the milling cutter 15, as the milling cutter 15 slides toward the second faucet 28, the second faucet 28 will squeeze the first trigger device 3 to slide upward, thereby causing the first trigger device 3 to send a signal, and the second hydraulic column 13 receives the signal, and the transmission shaft 12 is pulled up a certain distance by the second hydraulic column 13, thereby avoiding the situation where the milling cutter 15 is fully loaded and milling the faucet 28.

[0047] It should be noted that the milling amount of the milling cutter 15 is fixed, so it is only necessary to raise the milling cutter 15 by half the milling amount.

[0048] Subsequently, after the milling cutter 15 mills the second faucet 28, since the milling cutter 15 is lifted up first during milling, it needs to be milled again, so that it contacts the second faucet 28 through the second trigger device 5. When the second trigger device 5 is contacted by the second faucet 28, the second trigger device 5 will send a signal to the motor of the mobile platform 11, causing the motor of the mobile platform 11 to reverse, and the second hydraulic column 13 will push the milling cutter 15 down to the milling position after receiving the signal, and then drive the second faucet 28 in the opposite direction through the mobile platform 11 to contact the milling cutter 15 again for milling, so that the faucet 28 with excessive residual material can be automatically identified and the milling cutter 15 can be adjusted for milling. It is no longer necessary to measure each faucet 28 individually to set coordinate points and program it. It can be automatically identified through the cooperation of the first trigger device 3 and the second trigger device 5. Therefore, only a simple program is needed to deal with the situation where there is too much residual material in milling the faucet 28.

[0049] according to Figure 4 As shown, a round shaft 71 and a friction strip 72 are installed inside the transmission shaft 12. When the milling cutter 15 rotates, the milling cutter 15 drives the friction strip 72 to rotate together. Since the friction strip 72 is made of soft material, the friction strip 72 is driven to rotate by the milling cutter 15. The friction strip 72 rotates on the lower end surface of the receiving groove 75 under the action of centrifugal force. The high-speed rotating friction strip 72 is used to rub the end surface of the faucet 28, so as to remove burrs on the faucet 28.

[0050] It should be particularly noted that a receiving groove 75 is provided at the lower end of the milling cutter 15 . When the friction strip 72 and the faucet 28 conflict with each other, the friction strip 72 is squeezed by the faucet 28 and received in the receiving groove 75 , thereby preventing the friction strip 72 from affecting the milling of the milling cutter 15 .

[0051] Example 2

[0052] This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-5 The first trigger device 3 and the second trigger device 5 have the same structure, both of which include a slide groove 34 arranged on the hydraulic cylinder 41, one end of the slide groove 34 is slidably connected with a connecting block 36, the connecting block 36 and the tool holder 4 are connected through a first spring 37, one end of the connecting block 36 is installed with a second rod 32 and a first rod 31, the lower end of the first rod 31 is installed with a contact block 33, and a first button 35 is installed inside the tool holder 4, and the connecting block 36 is used to squeeze the first button 35.

[0053] One end of the connecting block 36 is rotatably connected to a pressing plate 39 , and the pressing plate 39 and the connecting block 36 are connected via a spring sheet 30 . A limiting plate 38 is also installed at one end of the connecting block 36 , and the pressing plate 39 can be operably abutted against the limiting plate 38 .

[0054] See also Figure 4 and Figure 5 When the second faucet 28 squeezes the contact block 33 to slide upward, the squeezing plate 39 is driven to slide upward through the first rod 31, the second rod 32 and the connecting block 36. At this time, the first button 35 is not squeezed first to prevent the milling cutter 15 from being lifted up while it is still milling the first faucet 28. The contact block 33 is squeezed upward by the second faucet 28 first, and then when the milling cutter 15 completes milling of the first faucet 28 and approaches the second faucet 28, its contact block 33 will inevitably slide off the second faucet 28, thereby contacting the first button 35 through the squeezing plate 39 on the connecting block 36, and limiting the squeezing plate 39 through the limiting plate 38, so that the squeezing plate 39 can only squeeze the first button 35. The ratchet structure can be referred to, and the structural principle is the same, so that only after the current faucet 28 is processed, the contact block 33 will send a signal of whether the milling cutter 15 needs to be lifted.

[0055] The sizes of the first rod 31 and the second rod 32 can be replaced and adjusted according to actual conditions to adapt to the distribution of the faucet 28 held by the adapter clamp 17 .

[0056] It should be particularly noted that the first trigger device 3 and the second trigger device 5 have the same structure. When the second trigger device 5 is hit by the faucet 28 , the signal of the second trigger device 5 takes precedence over the signal of the first trigger device 3 .

[0057] Example 3

[0058] This embodiment is an improvement made on the basis of embodiment 2. For details, please refer to Figure 1-9 , detection devices 6 are installed on both sides of the tool holder 4, and the detection device 6 includes a circular ring 64 sleeved on the transmission shaft 12, and a limit strip 65 is installed at one end of the circular ring 64.

[0059] A sliding groove 62 is provided at one end of the tool holder 4, and a square column 69 is slidably connected inside the sliding groove 62. A square sleeve 68 is sleeved on one side of the square column 69, and a detection plate 61 is installed on one side of the square sleeve 68. A second groove 67 and a first groove 66 are provided on the detection plate 61. The square sleeve 68 is slidably connected to the second groove 67, and the limit strip 65 is slidably connected to the first groove 66. A second button 63 is installed inside the sliding groove 62, and the square column 69 is used to squeeze the second button 63.

[0060] See also Figure 8 and Fig. 9 , are top views of the two milling situations, Figure 8 The size of the middle milling cutter 15 is larger than the faucet 28, so the faucet 28 can be completely milled. Fig. 9 The size of the milling cutter 15 is smaller than the faucet 28, so that after the milling cutter 15 mills a circle, some residual material will remain on the faucet 28, or other residual material will remain when the faucet 28 is cast. In order to deal with this situation, a detection device 6 is installed on both sides of the tool holder 4, see Figure 6 As shown, the outer surface of the transmission shaft 12 is sleeved with a circular ring 64, and one end of the circular ring 64 is installed with a limit strip 65. The limit strip 65 is slidably connected to the detection plate 61, and the detection plate 61 is located at the rear position of the maximum diameter of the milling cutter 15. When the milling cutter 15 cuts the residual material, the detection plate 61 will contact the residual material, so that the residual material will squeeze the detection plate 61 to slide, thereby sliding and squeezing the second button 63 through the detection plate 61, and a signal is sent through the second button 63, so that the first hydraulic column 14 hydraulically drives the transmission shaft 12 and the milling cutter 15 to slide significantly along the through groove 27, thereby increasing the milling area of ​​the milling cutter 15, thereby avoiding the occurrence of residual material.

[0061] It should be particularly noted that when the first hydraulic column 14 drives the transmission shaft 12 to slide back and forth, the transmission shaft 12 will also pull the two detection plates 61 to slide through the circular ring 64, and the sliding of the detection plates 61 is achieved through the cooperation of the square sleeve 68 and the square column 69.

[0062] Example 4

[0063] This embodiment is an improvement made on the basis of embodiment 3. For details, please refer to Figure 1-12A circular ring 73 is installed inside the transmission shaft 12, and a second spring 74 is installed on the outer surface of the circular shaft rod 71. The second spring 74 is connected to the circular shaft rod 71, and the second spring 74 abuts against the upper end surface of the circular ring 73. An extrusion column 16 is installed at one end of the transmission shaft 12, and a conical disk 22 is also installed on the outer surface of the circular shaft rod 71. The extrusion column 16 can be operated to squeeze the conical disk 22 to slide downward.

[0064] A protrusion 21 is also installed inside the through groove 27, and the squeezing column 16 can be operated to squeeze the protrusion 21 to slide;

[0065] A gear ring 23 is installed on the inner wall of the transmission shaft 12, a short shaft 26 is also installed on the lower end of the second hydraulic column 13, a first gear 24 is installed on the lower end of the short shaft 26, and a second gear 25 is installed on the upper end surface of the round shaft rod 71. The gear ring 23 meshes with the first gear 24, and the first gear 24 meshes with the second gear 25.

[0066] See also Figure 3 The outer surface of the transmission shaft 12 is also slidably connected with an extrusion column 16. When the transmission shaft 12 rotates, the transmission shaft 12 will abut against the protrusion 21. Fig.12 As shown, the protrusion 21 will squeeze the squeezing column 16 to slide toward the axis of the transmission shaft 12, and squeeze the cone disk 22 through the squeezing column 16. When the squeezing column 16 squeezes the cone disk 22 to slide downward, the cone disk 22 drives the round shaft rod 71 to slide downward. When the squeezing column 16 no longer squeezes the cone disk 22, the elastic potential energy of the second spring 74 pulls the round shaft rod 71 to slide upward. In this way, according to Figure 4 As shown, when the round shaft rod 71 slides up and down, the round shaft rod 71 drives the friction strip 72 to slide up and down, and the friction strip 72 is used to rotate up and down to rub the faucet 28, so as to better rub and remove the burrs on the faucet 28.

[0067] according to Fig.12 As shown, in order to improve the removal effect of the friction strip 72, the first gear 24 is rotatably connected to the lower end of the second hydraulic column 13. When the transmission shaft 12 rotates, the transmission shaft 12 will drive the internal ring gear 23 to rotate, the ring gear 23 drives the first gear 24 to rotate, the first gear 24 drives the second gear 25 to rotate, and the second gear 25 drives the round shaft rod 71 to rotate, so that the rotation speed of the round shaft rod 71 is different from the rotation speed of the transmission shaft 12, so that the round shaft rod 71 and the friction strip 72 can autonomously rub the burrs on the faucet 28, thereby improving the friction effect.

[0068] Example 5

[0069] This embodiment is an improvement made on the basis of embodiment 4. For details, please refer to Figure 1-12 , a transmission device 8 is installed at one end of the tool holder 4, and the transmission device 8 is used to drive the transmission shaft 12 to rotate;

[0070] The transmission device 8 includes a power device 81 installed at one end of the tool holder 4, a round rod 82 is installed at the lower end of the power device 81, a smooth ring 85 is sleeved on the outer surface of the transmission shaft 12, and a strip groove 86 is also provided on the outer surface of the transmission shaft 12. A limit block 87 is installed on the smooth ring 85, and the limit block 87 is slidably connected to the strip groove 86. A baffle 88 is also installed inside the tool holder 4, and the smooth ring 85 abuts against the baffle 88. At least one telescopic column 84 is provided on the outer surface of the smooth ring 85, and a belt 83 is sleeved between the round rod 82 and the telescopic column 84.

[0071] The telescopic column 84 includes a circular sleeve, a push column, a third spring and an arc plate. The circular sleeve is installed on the smooth ring 85. A push column is installed at one end of the circular sleeve. An arc plate is installed at one end of the push column. The third spring is connected between the circular sleeve and the push column.

[0072] The belt 83 is driven to rotate by the round rod 82 , the belt 83 drives the telescopic column 84 to rotate, and the telescopic column 84 drives the transmission shaft 12 to rotate.

[0073] When the second hydraulic column 13 drives the transmission shaft 12 to move upward, the smooth ring 85 will be slidably connected to the transmission shaft 12, so that the driving position of the belt 83 remains unchanged.

[0074] When the first hydraulic column 14 drives the second hydraulic column 13 to slide back and forth to remove the excess material, the belt 83 pulls the telescopic column 84 to adjust the wheelbase, thereby lengthening the size of the belt 83, so that when the second hydraulic column 13 slides back and forth, the belt 83 can still drive the transmission shaft 12 to rotate.

For details, please refer to Figure 1-12 A hydraulic cylinder 41 is installed inside the tool holder 4, a hydraulic rod 42 is installed at the upper end of the hydraulic cylinder 41, a second solenoid valve 44 and a first solenoid valve 43 are installed on both sides of the hydraulic cylinder 41, a second delivery pipe 19 is installed at one end of the second solenoid valve 44, and the second delivery pipe 19 is connected to the first hydraulic column 14, a first delivery pipe 18 is installed at one end of the first solenoid valve 43, and the first delivery pipe 18 is connected to the second hydraulic column 13.

[0077] A pressure relief chamber 45 is also installed inside the tool holder 4 . A first one-way valve 46 and a second one-way valve 47 are installed at one end of the pressure relief chamber 45 . The first one-way valve 46 and the second one-way valve 47 are respectively connected to the hydraulic cylinder 41 .

[0078] By installing a hydraulic rod 42 inside the tool holder 4, the first hydraulic column 14 and the second hydraulic column 13 are piston cylinders. When the first trigger device 3 sends a signal, the first solenoid valve 43 opens the valve, and the hydraulic rod 42 moves, and the hydraulic rod 42 squeezes the liquid inside the hydraulic cylinder 41, and squeezes the liquid to the first delivery pipe 18 through the hydraulic rod 42, so that the liquid is delivered to the inside of the second hydraulic column 13, see Figure 3 , thereby lifting the milling cutter 15 upward, the movement of the first hydraulic column 14 is the same as the movement of the second hydraulic column 13, and no further details are given. A pressure relief chamber 45 is installed at one end of the hydraulic cylinder 41, and the hydraulic pressure squeezed by the hydraulic rod 42 is sufficient to push the first hydraulic column 14 and the second hydraulic column 13 to move. However, when only one valve of the first solenoid valve 43 and the second solenoid valve 44 is opened, the pressure will be overloaded, so the pressure is relieved through the pressure relief chamber 45. When the pressure value is too large, the second one-way valve 47 will be opened to allow excess liquid to enter the pressure relief chamber 45. When the hydraulic rod 42 is reset, the liquid is transmitted through the first one-way valve 46.

[0079] The present invention also provides a milling method of a milling machine tool for faucet processing, comprising the following steps:

[0080] S1, placing a number of faucets on the fixture 17 at the upper end of the mobile platform 11, and milling the end faces of the faucets with the milling cutter 15;

[0081] S2, using the first trigger device 3 to detect faucet end faces of different heights, when the faucet end face is higher than the set value, the second hydraulic column 13 pulls the milling cutter 15 upward to avoid large-scale milling of the faucet end face causing deformation of the faucet or wear and damage of the milling cutter 15;

[0082] S3, when there is residual material on the faucet, the residual material is contacted by the detection device 6, and the detection device 6 sends a signal, so that the first hydraulic column 14 drives the milling cutter 15 to slide back and forth, thereby milling the residual material;

[0083] S4, during the milling process, the friction strip 72 is rotated to hit and rub the burrs on the faucet using the friction strip 72 rotating at a high speed;

[0084] S5, the processing is completed, and the processed faucet is removed from the fixture 17.

[0085] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0086] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
