[0006] The applicant encountered the following problems while using existing water-jet polishing machines: The clamping and rotating device is typically located above the adhesive bonding station. The adhesive powder box at the adhesive bonding station contains adhesive powder, and the high-speed, high-frequency rotation of the clamping and rotating device (10-30 times per minute) is equivalent to a fan blowing the adhesive powder up, resulting in a large amount of suspended dust in the production workshop. Simultaneously, water-jet polishing requires a large amount of water, and the dust dissolves in the water, forming mud. In existing technology, to solve the dust problem, a dust extraction hood is installed directly above the clamping and rotating device to absorb the dust. However, even with the dust extraction hood, a small amount of dust still exists in the workshop. Alternatively, more workstations could be added so that the clamping and rotating device is not located above the adhesive bonding station, but this solution has the following problems: more workstations are required, increasing the energy consumption of each clamp and leading to increased costs. Summary of the Invention

[0007] To address the aforementioned issues, this invention provides a dust-free high-speed water-cooled drilling and polishing machine, adding two workstations to separate the fixture rotation device from the adhesive bonding station. In existing technologies, the adhesive bonding station involves numerous actions; separating the fixture rotation device from the adhesive bonding station allows for an increase in its speed. However, this increased speed necessitates increasing the processing speed of other workstations. This patent improves the fixture's moving speed and reduces the dwell time of the fixture at each workstation. Furthermore, the applicant discovered that in existing technologies, a high-frequency heating structure is installed on one side of the transfer station, with the high-frequency heating pipe and cooling pipe fixed to corresponding sliding blocks. The high-frequency heating tube is located inside the fixture and below the adapter before rotation. When the adapter rotates, the high-frequency heating tube moves outward to allow the rotating frame to rotate. Therefore, the five actions at the adapter station (high-frequency heating tube inward movement, high-frequency heating tube heating, high-frequency heating tube stopping heating and cooling tube operation, high-frequency heating tube outward movement, and rotating frame rotation) are the most time-consuming. To reduce the bottleneck of dwell time at each station, the applicant improved the adapter. In summary, this water drill polishing machine can increase the speed of water drill processing, ensure that the cost of a single fixture does not increase, and also reduce dust generation. The technical solution is as follows:

[0008] This invention provides a dust-free high-speed water-jet polishing machine, comprising a frame arranged in a front-to-back direction, two clamping and rotating devices at both ends of the frame, and two polishing production lines on both sides of the frame. Each polishing production line includes a clamping and rotating device and at least one polishing device. A connecting and cooperating device is provided between the two polishing production lines. The clamping and rotating devices are driven by corresponding servo motors. The connecting and cooperating device includes a rotating frame, a high-frequency heating structure, and two clamping seats on the left and right sides of the rotating frame. The high-frequency heating structure includes a high-frequency heating main unit, a high-frequency heating head, a high-frequency heating tube, and a cooling tube. The tube is located next to the high-frequency heating tube; the feature is that two empty workstations are added at both ends of the frame and the speed of the clamp translation device and the clamp rotation device is increased. The two clamp rotation devices are respectively located at the two empty workstations. No adhesive device is set at the empty workstations and no unloading device is set thereon. The connecting and mating device adds a high-frequency heating structure and reduces the rotation speed of the rotating frame. The two high-frequency heating tubes are respectively fixed on the left and right sides of the rotating frame and are respectively located at the two clamp seats. The two high-frequency heating heads are respectively located on the upper and lower sides of the rotating frame. The two cooling tubes are respectively fixed on the left and right sides of the rotating frame.

[0009] In this embodiment of the invention, the two polishing production lines are arranged in a ring via two clamping and rotating devices. One polishing production line sequentially includes a first empty station 101, a first adhesive bonding station 102, a loading station 103, at least one first grinding and polishing station, a first water blowing station 108, a first transfer station 109, a first unloading station 110, and a second empty station 111. The other polishing production line sequentially includes a third empty station 201, a second adhesive bonding station 202, a second transfer station 203, and a cooling station 204. The facility includes at least one second grinding and polishing station, a second water blowing station 209, a heating station 210, and a second unloading station 211. The first transfer station 109 and the second transfer station 203 are arranged back-to-back and are equipped with a transfer and fitting device. The first empty station 101 and the second unloading station 211 are arranged back-to-back and are equipped with a clamping and rotating device. The second empty station 111 and the third empty station 201 are arranged back-to-back and are equipped with another clamping and rotating device. Each grinding and polishing station is equipped with a grinding and polishing device.

[0010] Specifically, in this embodiment of the invention, both polishing production lines are provided with four grinding and polishing stations, which include two grinding stations and two polishing stations arranged in sequence. Correspondingly, there are 11 stations on each side of the frame.

[0011] Furthermore, in this embodiment of the invention, the translation servo motor is connected to the fixture translation device via a rack and pinion drive structure; the speed of the fixture translation device is increased by increasing the power of the translation servo motor and increasing the number of teeth on the gear on the output shaft of the translation servo motor.

[0012] Specifically, in this embodiment of the invention, the movement time of the fixture at each station is 0.5-0.6s, and the dwell time at each station is 1.5-1.8s; the rotation time of the rotating frame is 1.5-1.8s, and the power of the translation servo motor is 10-15KW with 50-70 teeth on its gears.

[0013] Furthermore, the clamp translation device in this embodiment of the invention is provided with a fork lifting structure, and the grinding and polishing device is provided with a surface changing drive structure. Both the fork lifting structure and the surface changing drive structure are driven by corresponding servo motors.

[0014] The face-changing drive structure in this embodiment includes a slide rail 1 mounted on the frame in the left-right direction, a slider 2 on the slide rail 1, a face-changing motor mounting plate 3 mounted vertically on the slider 2, a face-changing connector 4 at the lower part of the face-changing motor mounting plate 3, a face-changing motor 5 at the upper part of the face-changing motor mounting plate 3 for driving the face-changing connector 4, and a translation mechanism for driving the slider 2 to slide forward and backward. The translation mechanism includes a face-changing servo motor 6, a crank 7 on the drive shaft of the face-changing servo motor 6, a slider connecting seat 8 on the slider 2, and a connecting rod 9 arranged in the forward and backward direction. The face-changing servo motor 6 is arranged vertically and is located inside the slider 2. The connecting rod 9 is located above or below the slide rail 1, and its two ends are respectively hinged to the slider connecting seat 8 and the crank 7 through vertical pins.

[0015] In this embodiment of the invention, the fork lifting structure includes a fork shaft, multiple forks spaced back-to-back on the fork shaft, a T-shaped transmission box, and a fork servo motor. The fork shaft is arranged in the front-to-back direction and is rotatably mounted on a clamp translation device. The T-shaped transmission box and the fork servo motor are both fixed on the clamp translation device. The fork servo motor is connected to the input shaft of the T-shaped transmission box. The output shaft of the T-shaped transmission box is arranged in the front-to-back direction and has upper synchronous pulleys coaxially at both ends. A lower synchronous pulley is coaxially arranged on the fork shaft and directly below each upper synchronous pulley. The upper synchronous pulleys are connected to the lower synchronous pulleys directly below them via synchronous belt transmission.

[0016] Specifically, in this embodiment of the invention, two high-frequency heating main units are respectively located on the left and right sides of the frame. The middle part of the rotating frame is rotatably mounted on the frame via a front-to-back rotating shaft. The rotating shaft is a hollow shaft with through holes on both its upper and lower sides. The clamp seat is located directly below the clamp translation device and includes a fixed clamp seat and a movable clamp seat. The fixed clamp seat and the movable clamp seat are arranged opposite each other vertically. The movable clamp seat is driven to move up and down by a corresponding cylinder. The high-frequency heating structure also includes insulating seats on the left and right sides of the rotating frame. The high-frequency heating tube is arranged in the front-to-back direction, with its front and rear ends fixed on the insulating seats on the corresponding sides. It is located between the fixed clamp seat and the movable clamp seat. The cooling tube is arranged in the front-to-back direction, with its front and rear ends fixed on the insulating seats on the corresponding sides. It has an air blowing hole on its inner side, located on the outer side of the high-frequency heating tube on the corresponding side. The water cooling tube of the high-frequency heating head passes through the through hole and then exits from the end of the rotating shaft, finally connecting to the water cooling circulation structure. The air tube of the cooling tube passes through the through hole and then exits from the end of the rotating shaft, finally connecting to the air supply structure.

[0017] Preferably, in this embodiment of the invention, the high-frequency heating tube is preheated during the process of moving from the second transfer station 203 to the first transfer station 109, and the corresponding cooling tube is not ventilated; the high-frequency heating tube does not work during the process of moving from the first transfer station 109 to the second transfer station 203, and the corresponding cooling tube is ventilated.

[0018] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0019] (1) Two workstations were added to separate the fixture rotation device from the adhesive bonding workstation, eliminating the need for dust hoods and ensuring that there is virtually no dust on the production site.

[0020] (2) Improve the speed of water drill processing. The processing time of each station can be reduced from about 3.0s to about 2.2s, that is, a water drill with a fixture can be output every 2.2s (processed), which improves production efficiency by about 27%.

[0021] (3) The cost of water drilling is approximately: energy consumption 30%, labor 30%, and raw materials 40%. Although the energy consumption of the water drilling polishing machine of this patent increases, the cost of water drilling per fixture does not increase due to the increased efficiency.

[0022] (4) Although the dwell time at each station is reduced, the number of actions is reduced from 5 to 2 (heating and rotation) due to the improved transfer and matching device. At the same time, the high-frequency heating tube can be preheated before heating. In fact, the heating time and cooling time (cooling is achieved during rotation) of the high-frequency heating tube are both extended, which can improve the docking accuracy and thus improve the yield rate. The yield rate can be increased from about 82% to about 85%. Attached Figure Description

[0030] To make the objectives, technical solutions, and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings.

[0031] Example 1

[0032] See Figure 2 Example 1 provides a dust-free high-speed water-cooled drilling and polishing machine, including a frame arranged in the front-to-back direction, two clamping and rotating devices at both ends of the frame, and two polishing production lines on both sides of the frame. The two polishing production lines are used to process pavilion surfaces and crown surfaces, respectively, and are connected in a ring by the two clamping and rotating devices. Each polishing production line includes a clamping and translating device and at least one grinding and polishing device, and may also include a powder feeding device, a material feeding device, a drying device, a heating device, or a drill unloading device as needed. A connecting and cooperating device is provided between the two polishing production lines. The clamping and translating device is driven to move in the front-to-back direction by a corresponding translation servo motor. The connecting and cooperating device includes a rotating frame, a high-frequency heating structure, and two clamping seats on the left and right sides of the rotating frame. The high-frequency heating structure includes a high-frequency heating host, a high-frequency heating head, a high-frequency heating tube, and a cooling tube. The high-frequency heating host, the high-frequency heating head, and the high-frequency heating tube are electrically connected in sequence and equipped with a water-cooling pipe, which is located next to the high-frequency heating tube. Two empty workstations are added at both ends of the frame, and the speeds of the fixture translation and rotation devices are increased (power needs to be increased). The two fixture rotation devices are respectively located at the two empty workstations. No adhesive bonding device is installed at the empty workstations, and a material unloading device may or may not be installed there; specifically, a material unloading device is installed at one empty workstation, and not at the other. A high-frequency heating structure (two in total) is added to the transition and mating device, and the rotation speed of the rotating frame is reduced. Two high-frequency heating tubes are fixed to the left and right sides of the rotating frame, respectively, and are located at the two fixture seats. The high-frequency heating tubes are arranged along the direction of fixture movement. Two high-frequency heating heads are located on the upper and lower sides of the rotating frame, respectively, and two cooling pipes are fixed to the left and right sides of the rotating frame, respectively.

[0033] Furthermore, in this embodiment of the invention, the translation servo motor is connected to the fixture translation device via a rack and pinion drive structure (existing structure). The speed of the fixture translation device is increased by increasing the power of the translation servo motor and increasing the number of teeth on the gear on the output shaft of the translation servo motor.

[0034] Specifically, for the 11-station configuration, the fixture in this embodiment of the invention has a movement time of 0.5-0.6 seconds at each station and a dwell time of 1.5-1.8 seconds at each station. The rotating frame has a flip time of 1.5-1.8 seconds, the translation servo motor has a power of 10-15 kW, and its gears have 50-70 teeth. In the prior art, the fixture has a movement time of 0.68 seconds at each station and a dwell time of 2.34 seconds at each station. The rotating frame has a flip time of less than 1.2 seconds, the translation servo motor has a power of 5.5 kW, and its gears have 28 teeth.

[0035] Specifically, in this embodiment of the invention, two high-frequency heating main units are respectively located on the left and right sides of the frame. The middle part of the rotating frame is rotatably mounted on the frame via a front-to-back rotating shaft. The rotating shaft is a hollow shaft with through holes on both its upper and lower sides. The rotating shaft is driven by a corresponding docking motor. Due to the addition of the high-frequency heating head, the power of the docking motor is increased, and the dual high-frequency heating head configuration also makes the rotation more stable. The clamping seat is located directly below the clamping translation device and includes a fixed clamping seat and a movable clamping seat. The fixed clamping seat and the movable clamping seat are arranged vertically opposite each other and both are arranged in the front-to-back direction. Both the fixed clamping seat and the movable clamping seat can fix the clamp and cooperate with the clamping translation device. The movable clamping seat is driven by a corresponding cylinder to move up and down (when the clamp is translated, the clamp is located above the high-frequency heating tube; when heating, the clamp moves downward to the high-frequency heating tube). The high-frequency heating structure also includes insulating seats on the left and right sides of the rotating frame. The high-frequency heating tube is arranged in a front-to-back direction, with its front and rear ends fixed to the corresponding insulating seats. It is located between the fixed clamp seat and the moving clamp seat, and its structure is the same as that of the prior art. The cooling tube is arranged in a front-to-back direction, with its front and rear ends fixed to the corresponding insulating seats. It has an air blowing hole on its inner side, located on the outer side of the high-frequency heating tube on the corresponding side, and its structure is the same as that of the prior art. The water cooling tube of the high-frequency heating head passes through the through hole and then exits from the end of the rotating shaft (front or rear end, specifically the end away from the drive motor), and finally connects to the water cooling circulation structure. The air tube of the cooling tube passes through the through hole and then exits from the end of the rotating shaft (front or rear end, specifically the end away from the drive motor), and finally connects to the air supply structure. The above structure ensures that the rotating frame can rotate.

[0036] Example 2

[0037] See Figure 2Example 2 provides a face-changing device for a water-drill grinding and polishing machine. Its structure is basically the same as that of Example 1, except that: in this example, a polishing production line (for processing glass beads) includes, in sequence, a first empty station 101, a first adhesive station 102, a feeding station 103, at least one first grinding and polishing station, a first water blowing station 108, a first transfer station 109, a first unloading station 110 (equivalent to a powder brushing station), and a second empty station 111. Another polishing production line (for processing the other end of the glass beads) includes, in sequence, a third empty station 201, a second adhesive station 202, a second transfer station 203, a cooling station 204, at least one second grinding and polishing station, a second water blowing station 209, a heating station 210, and a second unloading station 211. The cooling station 204 can be understood as an empty station to ensure stable transfer. Due to the addition of stations, in this patent, water blowing and heating can be set in two separate stations, and the second unloading station and the fixture rotation device are located in the same station. The first transfer station 109 and the second transfer station 203 are arranged back-to-back and are equipped with transfer and mating devices. The first empty station 101 and the second unloading station 211 are arranged back-to-back (forming an additional empty station) and are equipped with a clamping and rotating device. The second empty station 111 and the third empty station 201 are arranged back-to-back (forming another additional empty station) and are equipped with another clamping and rotating device. Each grinding and polishing station is equipped with a grinding and polishing device. The above is only one specific implementation of this embodiment. This embodiment can also adopt other implementations, such as another polishing production line that sequentially includes a third empty station, a second adhesive station, a second transfer station, a cooling station, at least one second grinding and polishing station, a second water blowing and heating station, a second unloading station, and a fourth station.

[0038] Specifically, in this embodiment of the invention, both polishing production lines are equipped with four grinding and polishing stations. The number of grinding and polishing stations can be set as needed. The four grinding and polishing stations include two grinding stations and two polishing stations arranged sequentially. Thus, one polishing production line sequentially includes a first empty station 101, a first adhesive bonding station 102, a loading station 103, two first grinding stations 104, two first polishing stations 106, a first water blowing station 108, a first transfer station 109, a first unloading station 110, and a second empty station 111. The other polishing production line sequentially includes a third empty station 201, a second adhesive bonding station 202, a second transfer station 203, a cooling station 204, two second grinding stations 205, two second polishing stations 207, a second water blowing station 209, a heating station 210, and a second unloading station 211. Correspondingly, there are 11 stations on each side of the frame.

[0039] Preferably, in this embodiment of the invention, the high-frequency heating tube is preheated during its movement from the second transfer station 203 to the first transfer station 109, and the corresponding cooling tube is not ventilated. During the movement of the high-frequency heating tube from the first transfer station 109 to the second transfer station 203, it is not operational, and the corresponding cooling tube is ventilated.

[0040] Example 3

[0041] Example 3 provides a face-changing device for a water-drill grinding and polishing machine. Its structure is basically the same as that of Example 2, except that: the two polishing production lines in this example are each equipped with six grinding and polishing stations. The six grinding and polishing stations include three grinding stations and three polishing stations arranged in sequence. Correspondingly, there are 13 stations on both sides of the frame.

[0042] Example 4

[0043] Example 4 provides a face-changing device for a water-drill grinding and polishing machine. Its structure is basically the same as that of Example 1, except that the clamping translation device in this example is equipped with a fork lifting structure, and the grinding and polishing device is equipped with a face-changing drive structure. Since the dwell time at each station is reduced, the speed of the processing devices at some stations needs to be increased. In the prior art, both the fork lifting structure and the face-changing drive structure are driven by corresponding cylinders and positioned by a buffer block made of elastic material. During positioning, the slider actually needs to move back and forth within a small range to achieve positioning, which takes time. To increase speed, both the fork lifting structure and the face-changing drive structure in this example are driven by corresponding servo motors.

[0044] Among them, see Figure 3-4 The face-changing drive structure in this embodiment of the invention includes a slide rail 1 mounted on the frame in a left-right direction, a slider 2 on the slide rail 1, a face-changing motor mounting plate 3 mounted vertically on the slider 2, a face-changing connector 4 at the lower part of the face-changing motor mounting plate 3, a face-changing motor 5 at the upper part of the face-changing motor mounting plate 3 for driving the face-changing connector 4, and a translation mechanism for driving the slider 2 to slide back and forth. The translation mechanism includes a face-changing servo motor 6, a crank 7 on the drive shaft of the face-changing servo motor 6, a slider connecting seat 8 on the slider 2, and a connecting rod 9 arranged in a back-to-back direction. The face-changing servo motor 6 is vertically arranged and located inside the slider 2. The connecting rod 9 is located above or below the slide rail 1 (preferably below to reduce the influence of dust), and its two ends are hinged to the slider connecting seat 8 and the crank 7 respectively through vertical pins.

[0045] The fork lifting structure in this embodiment includes a fork shaft, multiple forks spaced back-to-back on the fork shaft, a T-shaped transmission box, and a fork servo motor. Each workstation corresponds to one fork, which can move to adjacent workstations. The fork shaft is arranged in the front-to-back direction and rotatably mounted on a fixture translation device. The T-shaped transmission box and the fork servo motor are both fixed to the fixture translation device. The fork servo motor is connected to the input shaft (vertically positioned) of the T-shaped transmission box, which is located above the T-shaped transmission box. The output shaft of the T-shaped transmission box is arranged in the front-to-back direction, with two upper synchronous pulleys coaxially at both ends. Two lower synchronous pulleys (located in front and behind a fork) are coaxially positioned on the fork shaft and directly below each upper synchronous pulley. The upper synchronous pulleys are connected to their corresponding lower synchronous pulleys via a synchronous belt (vertically positioned).

[0046] Example 5

[0047] Example 5 provides a face-changing device for a water-jet polishing machine. Its structure is basically the same as that of Example 1, except that: in this embodiment, the clamp's movement time at each station is 0.55s, and its dwell time at each station is 1.65s. The rotating frame's flipping time is 1.5s, and the translational servo motor has a power of 13KW and its gears have 60 teeth.

[0048] In this embodiment of the invention, "first", "second", "third" and "fourth" serve only as distinguishing terms and have no other special meaning.

[0049] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
