Description

Technical Field

[0001] The invention relates to the technical field of numerical control machining, in particular to a high-precision boring device for a frame of a diamond wire cutting machine. Background Art

[0002] The diamond wire cutting machine is equipped with multiple transmission shafts for driving the diamond wire to rotate and cut objects. Among them, frames for supporting the transmission shaft are provided at both ends of the transmission shaft, so that the transmission shaft can be quickly installed on the bed of the diamond wire cutting machine. At the same time, the frames at both ends of the transmission shaft need to ensure that they are coaxial after installation to meet high-precision cutting requirements. Especially for equipment for cutting semiconductors, the installation accuracy requirements are higher. Therefore, when processing pairs of frames, different processing accuracy causes the paired frame shaft holes to be unable to ensure coaxiality after installation, making it impossible to adjust the coaxiality of the transmission shaft after installation, affecting the processing accuracy.

[0003] In the prior art, conventional boring machines bore a frame independently each time they bore a hole. As a result, it is impossible to ensure that the mounting holes of the two frames used in a group after installation are aligned in the same axial direction during boring. This causes a decrease in subsequent transmission accuracy, and the mounting holes of two adjacent parts cannot be kept on the same axis, which increases the resistance of the transmission process and thus reduces the transmission efficiency.

[0004] Secondly, it is difficult to find the positioning reference point during boring, resulting in the inability to ensure that the two frames are aligned each time boring, affecting the boring accuracy. Summary of the Invention

[0005] The purpose of the present invention is to address the shortcomings of the existing technology and provide a high-precision boring equipment for a frame of a diamond wire cutting machine. First, the end faces of the two sets of frames installed on the positioning and adjustment unit are fine-ground, and the fine-ground surfaces are used as the boring positioning reference surfaces to ensure that the two sets of frames pressed together remain on the same axis during boring, thereby improving the processing accuracy. In addition, by fine-tuning the coaxial components inserted into the interior of the two sets of frames and expanding them outward, the holes to be bored by the two sets of frames remain on the same axis, further improving the subsequent boring accuracy, thereby improving the processing accuracy of the synchronous processing of the cutting machine.

[0133] The fixing sleeve 304 is configured to be in an arc shape.

[0134] As an improvement, a guide plate 3011 is connected to the middle of the lower end of the fixing seat 301;

[0136] A second guide groove 3021 is provided inside the mounting seat 302 and outside the guide plate 3011;

[0140] A tightening rod 3023 is slidably inserted into the third guide groove 3022 for adjusting the position of the mounting seat 302 relative to the guide plate 3011;

[0141] A second pre-tightening spring 3024 is sleeved outside the tightening rod 3023 and inside the third guide groove 3022 .

[0142] Furthermore, Figure 9 As shown, an extension rod 3012 is connected to the lower end of the fixing seat 301 and located on the side of the mounting seat 302;

[0143] The extension rod 3012 is provided with a threaded hole 30121 inside;

[0144] A threaded tightening rod 3013 for locating the mounting seat 302 is rotatably connected to the threaded hole 30121 .

[0145] It should be added that the driving motors in the present invention preferably use electrical signals to control the automatic start and stop sequence.

[0146] It should be noted that, when in use, the two sets of matching racks are placed on the left and right sets of mounting bases 302 respectively and the end of the rack that needs to be bored is inserted into the pre-insertion hole 3020. Figure 2 As shown, the second cylinder 303 is started, and the second cylinder 303 drives the fixing sleeve 304 to move downward to press the machine frame to be processed onto the mounting base 302, and the clamping shaft 305 at the lower part of the fixing sleeve 304 is pushed into the C hole at the lower part of the machine frame, completing the installation of the machine frame;

[0147] Start the first cylinder 221, which drives the grinding wheel 224 downward to the end face of the frame through the telescopic rod 223, and then starts the driving motor for driving the grinding wheel 224 to rotate. The driving motor drives the grinding wheel 224 to rotate, and at the same time starts the driving motor at the lower part of the driving gear 212. The driving motor drives the racks 215 meshed with it on both sides to rotate through the driving gear 212, and the racks 215 drive the guide blocks 213 to move along the third guide rail 2111 through the support beam 214. The guide blocks 213 drive the mounting blocks 302 to move through the fixed seats 301, and the two sets of mounting seats 302 synchronously drive the frames to move toward each other to the rotating grinding wheel 224. Figure 3 As shown, the connection end of the supporting rack is further ground flat, thereby reducing the defect of uneven connection end surface of the subsequent supporting rack that reduces installation accuracy;

[0148] After the end surface of the rack used in conjunction is ground flat, the first cylinder 221 drives the grinding wheel 224 to move upward to the initial position through the telescopic rod 223. At this time, Figure 4-Figure 8 As shown, the first support seat 1112 drives the adjustment cylinder 112 to move along the first guide rail 1111 and inserts it into the holes a and b at both ends of the matching frame in sequence. Subsequently, the driving motor for driving the rotating shaft 113 in the first support seat 1112 drives the push rod 1131 to rotate through the rotating shaft 113, and the push rod 1131 cooperates with the first inclined portion 11311 and the second inclined portion 1140 to drive the coaxial rod 114 to move upward along the through slot 1121, so that the multiple groups of coaxial rods 114 are synchronously pushed to the inner walls of the a and b holes, so that the a and b holes that were originally not on the same axis are moved to the same axis under the outward pushing force of the coaxial rod 114, thereby achieving the effect of inserting the coaxial assembly 11 into the two groups of frames for outward expansion, so that the holes to be bored in the two groups of frames are on the same axis, further improving the subsequent boring accuracy.

[0149] It should be noted that, in the present invention, when the coaxial rod 114 expands outward in the a and b holes, the two sets of racks are always mounted on the mounting base 302 during this process. If the two sets of racks are misaligned, such as Figure 9 、 Figure 10 As shown, as the coaxial rod 114 expands in the a and b holes, the guide plate 3011 moves upward or downward along the second guide slot 3021, causing the guide plate 3011 to push the tightening rod 3023 upward or downward to compress the second preload spring 3024 and move along the third guide slot 3022. Until the two sets of racks are aligned up and down, the guide plate 3011 stops moving up and down relative to the second guide slot 3021. If the two sets of racks are misaligned left and right, the mounting seat 302 will slide along the guide plate 3011 relative to one end of the tightening rod 3023 until the two sets of corresponding a and b holes are completely on the same axis. The threaded tightening rod 3013 is rotated, and the threaded tightening rod 3013 rotates along the threaded hole 30121 and moves toward the mounting seat. The mounting seat 302 moves, so that the mounting seat 302 is fixed, and the rotating shaft 113 is rotated in the opposite direction, so that the coaxial rod 114 is reset under the elastic force of the first preloaded spring 1143 and the limit block 1141, and the first support seat 1112 is controlled to move along the first guide rail 1111 to bring out the adjusting cylinder 112. The mounting seat 302 presses the two sets of frame end faces after fine grinding under the transmission action of the driving gear 212, so that the subsequent boring is carried out with the fine grinding end faces as the reference, thereby achieving the end face fine grinding of the two sets of frames installed on the positioning and adjusting unit 3, and using the fine grinding surface as the boring positioning reference surface, ensuring that the two sets of frames pressed together remain on the same axis during boring, thereby improving the processing accuracy.

[0151] like Figure 11 As shown, the components identical or corresponding to those in the first embodiment are designated by the corresponding reference numerals in the first embodiment. For simplicity, only the differences from the first embodiment are described below. The second embodiment differs from the first embodiment in that:

[0152] The boring assembly 12 comprises:

[0154] The upper end of the second base 121 is connected to a second guide rail 1211;

[0155] A driving mechanism is provided at the connection between the second support base 122 and the second guide rail 1211 for driving the second support base 122 to move along the second guide rail 1211;

[0156] A driving motor for driving the rotating column 123 to rotate is provided at the connection between the second supporting base 122 and the rotating column 123;

[0157] The upper end of the second guide rail 1211 is slidably connected to the second support base 122;

[0158] The second support seat 122 is internally rotatably connected to a rotating column 123;

[0159] A boring tool 124 is installed at one end of the outer side of the rotating column 123 .

[0160] It should be noted that the two holes a and b to be bored in the two sets of racks used in conjunction are on the same axis, and then the second support seat 122 is controlled to move along the second guide rail 1211, and the second support seat 122 is controlled to drive the rotating column 123 to rotate. The rotating column 123 drives the boring tool 124 to rotate and pass through the b and a holes in turn to bore the matching racks, thereby achieving the goal of boring two parts of the racks at one time, and the boring efficiency is high.

[0161] 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 and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
