Description

Technical Field

[0001] The invention relates to the technical field of metal precision engraving, in particular to automated precision engraving equipment for a metal keyboard frame. Background Art

[0002] Metal keyboards are generally made of aluminum alloy or other metals. Due to different usage environments, most factory controls require metal keyboards or some high-end customized keyboards are also metal keyboards. When making such keyboards, a precision engraving machine is often required to engrave characters or specially customized patterns or logos on the metal keyboard to achieve durable, beautiful and high-end visual and practical effects. However, in the actual precision engraving process, the precision engraving characters required for the keyboard are relatively small, and the waste chips generated by the precision engraving of the tool head often have no time to be discharged, and will accumulate at the precision engraving tool head, thereby affecting the precision engraving effect. In addition, the tool head needs to be continuously cooled during the precision engraving process to avoid overheating and damage to the tool head. The existing technology generally uses wind blowing or water pipes to dissipate heat. The wind blowing effect is poor, and the waste chips are raised, affecting the cleanliness of the working environment. The water pipes are always facing the heat dissipation. In order to save water resources as much as possible, the water flow is generally small, so it is not conducive to waste discharge, and the cooled water is directly discharged, which is not conducive to resource recycling. The effects of the above two methods are not very ideal.

[0016] S2: Turn on the lifting cylinder, so that the lifting cylinder drives the mounting platform to move down and sink under the water surface of the base frame, and be flush with the position of the isolation plate;

[0017] S3: Adjust the engraving machine to achieve alignment, and then perform engraving. When engraving starts, turn on the circulation pump. During engraving, the circulation pump continuously delivers water from the top of the mounting table to the bottom of the mounting table through the circulation channel, so that the water flow on the top of the mounting table maintains a circulation effect of flowing from all sides to the edge, and the waste chips produced by the engraving carried by the water flow are promptly washed away and concentrated on the isolation plate;

[0019] S4: After the fine carving is completed, the circulation pump is turned off, and the mounting table is raised by connecting the lifting cylinder, so that the finely carved keyboard frame is lifted out of the water surface and the finely carved keyboard frame is removed, and at the same time, the isolation plate is driven to rotate, and the waste chips accumulated on the isolation plate are dumped into the base frame for deposition.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] Before use, the base frame of the present invention is filled with suitable water or coolant, and the circulation pump is turned on during fine carving. During fine carving, the circulation pump continuously transports water from the top of the mounting platform to the bottom of the mounting platform through the circulation channel, so that the water flow on the top of the mounting platform maintains a circulation effect of flowing from all sides to the edge, and the waste chips generated by fine carving are promptly washed away and concentrated on the isolation plate by the water flow; during fine carving, the fine carving spindle drives the bottom cutter head to rotate and drives the spoiler fan to rotate at the same time, and the waste chips generated by fine carving are immediately rolled up by the water flow at the fine carving location, generating a large water flow impact force, flushing the waste chips generated by fine carving, and quickly dispersing the generated waste chips to the discharge port under the action of the centrifugal force of the water flow. The inner wall of the waste sleeve is flushed open by the water flow, so that the waste chips are discharged through the outer guard sheet, and the waste chips generated at the waste sleeve are promptly sent to the edge of the mounting table under the flow of external water flow, and the external water flows through the inner guard sheet and is filtered by the folded filter screen before re-entering the waste sleeve, so that the waste sleeve is replaced with new water without waste chips in time, and at the same time, it has a cooling effect on the precision carving spindle, and the cooling and waste water is the water filled in the base frame, without the need to constantly replenish water, which greatly reduces water consumption and saves water resources, and the immersion precision carving has a significant cooling effect and a significant waste discharge effect, and there will not be a lot of dust in the environment, etc., which greatly reduces the residual waste chips at the precision carving and improves the precision carving quality.

[0034] 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.

[0035] See also Figure 1-9 , the present invention provides a technical solution:

[0036] The automated fine carving equipment for a metal keyboard frame comprises a fine carving machine 1 and a fine carving spindle 2, wherein a base frame 3 is fixedly provided inside the fine carving machine 1, a mounting platform 4 is slidably connected inside the base frame 3, a plurality of circulation holes 5 are provided at the bottom of the mounting platform 4, water suction grooves 6 are fixedly connected to the four walls of the base frame 3, a circulating pump 7 is installed on the water suction grooves 6, isolation plates 8 are rotatably connected to the four walls of the base frame 3, a waste discharge sleeve 9 is matched and installed at the bottom of the fine carving spindle 2, a spoiler fan 10 is rotatably connected to the waste discharge sleeve 9, a plurality of through grooves 11 are provided on the outer wall of the waste discharge sleeve 9, inner guard plates 12 and outer guard plates 13 are rotatably connected to the through grooves 11, and a folded filter screen 14 is fixedly connected between the end of the inner guard plate 12 and the inner wall of the waste discharge sleeve 9.

[0037] Before use, the present invention first fills the base frame 3 with suitable water or coolant, installs the keyboard frame to be finely engraved on the mounting table 4, and installs the suitable waste discharge sleeve 9 on the fine engraving spindle 2; turns on the lifting cylinder 23, so that the lifting cylinder 23 drives the mounting table 4 to move down and sink under the water surface of the base frame 3, and is flush with the position of the isolation plate 8; adjusts the fine engraving machine 1 to achieve alignment, and then fine engraving is performed, and the circulation pump 7 is turned on at the beginning of fine engraving. During fine engraving, the circulation pump 7 always transports the water on the top of the mounting table 4 to the bottom of the mounting table 4 through the circulation channel 28, so that the water flow on the top of the mounting table 4 maintains a circulation effect of flowing from the surrounding to the edge, and the waste generated by fine engraving is carried by the water flow and is promptly washed away and concentrated on the isolation plate 8;

[0038] At the same time of fine carving, the fine carving main shaft 2 drives the bottom cutter head to rotate and drives the spoiler fan 10 to rotate at the same time. When the waste discharge sleeve 9 blocks the external water flow as much as possible, the spoiler fan 10 rotates to quickly disturb the water flow in the waste discharge sleeve 9, that is, the fine carving position of the cutter head, and immediately rolls up the waste generated by the fine carving through the water flow, generates a large water flow impact force, washes away the waste generated by the fine carving, and quickly disperses the generated waste to the inner wall of the waste discharge sleeve 9 under the action of the centrifugal force of the water flow, and flushes the outer guard sheet 13 open under the action of the water flow, so that the waste is discharged through the outer guard sheet 13 and discharged to the outside. The water flow will promptly deliver the waste chips produced at the waste discharge sleeve 9 to the edge of the mounting table 4, and the external water will re-enter the waste discharge sleeve 9 after being filtered through the folded filter screen at the inner guard plate 12, so that the waste discharge sleeve 9 will be replaced with new water without waste chips in time, and at the same time, it will cool down the fine carving spindle, and the cooling and waste water is the water filled in the base frame 3, and there is no need to replenish water all the time, which greatly reduces the water consumption and saves water resources. The immersion-type fine carving has a significant cooling effect and a significant waste discharge effect. There will not be a lot of dust in the environment, etc., which greatly reduces the residual waste chips at the fine carving and improves the quality of fine carving.

[0039] During fine carving, the mounting platform 4 and the isolation plate 8 form a closed plane to cover most of the water surface below the mounting platform 4, thereby minimizing the impact on the water at the bottom of the mounting platform 4 during fine carving water circulation and avoiding stirring up waste chips deposited at the bottom of the base frame 3.

[0040] After the fine carving is completed, the circulation pump 7 is turned off, and the mounting table 4 is raised by connecting the lifting cylinder 23, so that the finely carved keyboard frame is lifted out of the water surface and the finely carved keyboard frame is removed. At the same time, the isolation plate 8 is driven to rotate, and the waste accumulated on the isolation plate 8 is poured into the base frame 3 for deposition. After a period of use, the debris in the base frame 3 can be collected and removed, which is convenient for the recycling and reuse of waste. The water in the base frame 3 can also be replaced and used regularly.

[0041] Among them, the four walls of the mounting platform 4 are all provided with edge grooves, and the edge grooves are rotatably connected with rotating clamps 15. The rotating clamps 15 are located at the bottom of the mounting platform 4 and are rotatably connected with pull rods 16. A rotating driving member is provided at the bottom of the mounting platform 4, and the rotating driving member is used to drive the pull rod 16 to move and position.

[0042] Among them, the rotating driving part includes a fixed shaft 17 fixedly connected to the bottom of the mounting platform 4, the fixed shaft 17 is rotatably connected to a synchronous ring 18 outside, a plurality of inclined grooves 19 are provided inside the synchronous ring 18, the ends of the pull rod 16 are fixedly connected to a connecting shaft 20, the connecting shaft 20 corresponds to the inclined groove 19 and slides in cooperation, and the fixed shaft 17 is externally threadedly connected to a tightening sleeve 21.

[0043] Among them, a plurality of slide bars 22 are fixedly connected to the bottom of the synchronization ring 18 . The slide bars 22 are distributed around the tightening sleeve 21 and penetrate into the tightening sleeve 21 to slide with it. The tightening sleeve 21 is originally located at the bare rod section of the fixed shaft 17 .

[0044] The required fine-carved keyboard frame is installed on the mounting table 4. The specific steps are as follows: place the keyboard frame on the mounting table 4, manually rotate the tightening sleeve 21, and drive the synchronous ring 18 to rotate together through the slide rod 22. The rotation of the synchronous ring 18 drives the connecting shaft 20 to move in the inclined slide groove 19, so that the connecting shaft 20 approaches or moves away from the fixed shaft 17, thereby driving the rotating clamping plate 15 to rotate through the pull rod 16, so that the upper end of the connecting shaft 20 rotates inward to synchronously clamp the keyboard frame or rotates outward to release the keyboard frame. The inward clamping is achieved by the threaded connection between the tightening sleeve 21 and the fixed shaft 17 to achieve self-locking, fix the state of the rotating clamping plate 15, so that the keyboard frame is clamped and fixed inside, the fixation is simple and convenient, and the four sides are positioned at the same time, and the positioning is accurate. When fixing, since the rotating clamping plate 15 is in an inclined state, the contact with the four sides of the keyboard frame is line contact, which minimizes the damage of clamping and fixing.

[0045] Among them, a lifting cylinder 23 is fixedly installed in the base frame 3, and the output end of the lifting cylinder 23 is fixedly connected to the bottom of the mounting platform 4. The four walls of the base frame 3 are rotatably connected with a reversing rod 24. A reverse rope 25 is fixedly connected between the end of the isolation plate 8 and the bottom edge of the mounting platform 4, and the reverse rope 25 bypasses the reversing rod 24.

[0046] The four walls of the base frame 3 are rotatably connected with a supporting telescopic rod 26, one end of which is rotatably connected to the isolation plate 8. The four walls of the base frame 3 are fixedly connected with a fixed rod 27, one end of which is rotatably connected to the isolation plate 8. The transition point between the fixed rod 27 and the isolation plate 8 is located outside the transition point between the supporting telescopic rod 26 and the isolation plate 8. The supporting telescopic rod 26 is an elastic telescopic rod.

[0047] After the fine carving is completed, the lifting cylinder 23 lifts the mounting platform 4 out of the water and drives one end of the reverse rope 25 to move upward, thereby pulling the end of the isolation plate 8 to rotate downward around the end of the fixed rod 27. When the mounting platform 4 is raised to the highest position, the isolation plate 8 is pulled and rotated to 90 degrees, so that the debris accumulated on the top surface is completely poured into the base frame 3, and then deposited in the base frame 3, which is convenient for batch collection of debris and recycling.

[0048] A circulation channel 28 is provided on the inner wall of the base frame 3 , one end of the circulation channel 28 is located in the water absorption groove 6 and the other end is located below the mounting platform 4 . The water absorption end of the water absorption groove 6 is fixedly connected with a centralized filter screen 29 , and the bottom end of the circulation hole 5 is fixedly connected with a bottom filter screen 30 .

[0049] When the circulation pump 7 starts the circulating water flow, the water sucked through the water suction groove 6 is filtered through the centralized filter screen 29 and then enters the bottom of the mounting platform 4 through the circulation channel 28, so as to prevent debris from clogging the pump body or the circulation channel 28, and enable the debris to be concentrated on the isolation plate 8 at the centralized filter screen 29, so as to facilitate the dumping, collection and treatment of the debris. Thus, the water flowing back upward from the bottom of the mounting platform 4 passes through the circulation hole 5 and is filtered through the bottom filter screen 30 and then enters the top of the mounting platform 4, and is reused as flushing, waste discharge and cooling water.

[0050] A cross slide 31 is fixedly installed inside the precision engraving machine 1, a telescopic cylinder 32 is fixedly installed at the bottom of the cross slide 31, the output end of the telescopic cylinder 32 is fixedly connected to the precision engraving spindle 2, the waste discharge sleeve 9 is fixedly installed outside the precision engraving spindle 2 by bolts, and the spoiler fan 10 is installed outside the adapted cutter head.

[0051] The cross slide 31 provides the precision carving spindle 2 with freedom in the X and Y directions, so that the precision carving spindle 2 can reach any position of the mounting table 4. The telescopic cylinder 32 provides the precision carving spindle 2 with freedom in the Z direction, and can adjust the precision carving depth, so as to realize a variety of precision carving patterns and effects.
