Description

Technical Field

[0001] The invention relates to the technical field of taps, in particular to an automatic production system for taps. Background Art

[0002] A tap is a tool for machining internal threads, also called a screw tap. It has a groove along the axial direction and is widely used by operators in the manufacturing industry for tapping. Taps are the main tools for machining various medium and small-sized internal threads, used for cutting or trimming internal threads. For small-sized internal threads, taps are almost the only machining tool.

[0003] In the production process of taps, the taps are machined into cylindrical shapes by lathes, and the accuracy of their diameter and length is ensured. The outer surface of the taps is ground by grinders to improve their surface roughness and roundness. Grinding is also one of the main ways of finishing taps, because the tool steel after heat treatment is very hard and can only be processed by grinders. After that, the cutting part of the tap is sharpened by a sharpener to ensure the cutting performance and thread quality of the taps.

[0004] During the grinding process, the tap needs to be installed on the fixture of the grinder to ensure that it is firmly fixed. The position of the fixture should be adjusted so that the cutting part of the tap contacts the grinding wheel. The pressure and speed should be kept uniform during grinding to avoid over-sharpening or under-sharpening. Based on the above description, the tap needs to be adjusted and clamped during grinding, and the movement of the fixture or grinder needs to be controlled to achieve grinding. The operation requirements are high and the batch processing efficiency is low. At the same time, the positioning of the tap on the fixture is inaccurate, which may cause the shape deviation of the cutting part of the tap after grinding, affecting the processing accuracy of the thread. The grinding wheel grinds the cutting part of the tap unevenly, which may cause inconsistent sharpness of the cutting edge and affect the processing quality of the thread. Summary of the invention

DETAILED DESCRIPTION

[0030] 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.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: when processing taps, in many cases only one tap can be processed, and the processing efficiency is not high. Since the taps need to be fixed during the processing of the taps, the tool needs to be aligned afterwards. Even if batch processing can be carried out without tool alignment, the taps still need to be clamped. Even if the clamping is very fast, the equipment that meets the above requirements is often expensive, and the processing cost is relatively expensive. The equipment that can reduce the cost and automatically process the taps in batches currently needs to be further improved. A tap automatic production system is proposed, such as Figure 1 As shown, the equipment for processing the tap body 5, its various components as shown in the figure, include a base 1, a clamping part 2 and a supporting part 3 are installed on the base 1, the tap body 5 is clamped between the clamping part 2 and the supporting part 3, and a grinding part 4 for processing the tap body 5 is also installed on the base 1, the clamping part 2 and the supporting part 3 limit the tap body 5, so that the grinding part 4 processes the tap body 5, and realizes the forming of the outer cutting cone of the tap body 5;

[0032] like Figure 3 As shown, the grinding part 4 includes a support seat 41 fixed on the base 1 and a cutting disc 42 that can slide along the support seat 41. The upper end of the cutting disc 42 is used to cut the cutting cone from the tap body 5. When the tap body 5 is processed, the cutting disc 42 needs to grind the surface of the tap body 5 to form the cutting cone. The grinding operation is performed, and the cutting cone can be easily processed even if the tap body 5 has been heat-treated.

[0033] like Figure 2As shown, the clamping part 2 includes a fixing seat 11, a clamping motor 12 and a clamping plate 13;

[0034] The fixing seat 11 is fixed on the base 1, one end of the fixing seat 11 is fixed to the clamping motor 12, and the other end is connected to the clamping plate 13, the clamping plate 13 is connected to the clamping motor 12, the clamping plate 13 is used to limit the tap body 5, and the clamping motor 12 is used to drive the rotation of the tap body 5 so that the tap body 5 can be processed at any position.

[0035] like Figure 2 and Figure 3 As shown, the support portion 3 includes a second fixing seat 31 fixed on the base 1, and a mounting groove 311 is provided at the upper end of the second fixing seat 31. A hydraulic cylinder 33 is provided in the mounting groove 311. The hydraulic cylinder 33 is used to abut against the tap body 5 on the clamping plate 13. A limiting ring layer 32 is rotatably installed on the outer end of the hydraulic cylinder 33. The limiting ring layer 32 is rotatably installed in the mounting groove 311 and is used to control the rotation of the tap body 5. The hydraulic cylinder 33 abuts the tap body 5 against the mounting hole 132. Therefore, even in the case of rotation, the tap body 5 will not move outward, so that the tap body 5 is limited. In addition, under the action of the hydraulic cylinder 33 and the mounting hole 132, the tap body 5 is sleeved in the mounting hole 132, and the tap body 5 fits against the inner wall of the mounting hole 132, so that the tap body 5 is prevented from tilting, thereby achieving a stable effect.

[0036] like Figure 5 As shown, the clamping disk 13 includes a disk body 131 and an inner supporting spring 133. One side of the disk body 131 is fixed to the output end of the clamping motor 12, and the other side thereof is provided with a mounting hole 132. The inner supporting spring 133 is fixed in the mounting hole 132. The tap body 5 is sleeved in the mounting hole 132 and abuts against the inner supporting spring 133. The inner end of the tap body 5 abuts against the inner supporting spring 133, and the inner supporting spring 133 is squeezed to the innermost end, which is also the position where the tap body 5 needs to be processed and positioned, ensuring that both ends of the tap body 5 are limited so that the tap body 5 rotates. Then, the hydraulic cylinder 33 is loosened, so that the inner supporting spring 133 can push the tap body 5 outward, automatically causing the tap body 5 to fall, completing the processing of the tap, and also facilitating the installation of the tap body 5 to be processed later.

[0037] like Figure 5As shown, a slide groove 411 is provided at the upper end of the support seat 41, and an internal threaded shaft 412 is rotatably installed inside the slide groove 411. One end of the internal threaded shaft 412 extends out of the slide groove 411, and a transmission gear 413 is fixed to the extended end of the internal threaded shaft 412. A driving gear 134 is fixedly sleeved on the outer side of the disk body 131, and the driving gear 134 is meshed with the transmission gear 413. The blade disk 42 is arranged at the upper end of the support seat 41. When the internal threaded shaft 412 rotates, it can drive the blade disk 42 to move horizontally, so as to cut the cutting on the tap body 5. The driving gear 134 is meshed with the transmission gear 413. When the tap body 5 rotates, the cutting disc 42 also moves horizontally, so that a uniform cutting cone is processed on the working part of the tap body 5. The rotation of the clamping disc 13 and the horizontal movement of the cutting disc 42 work simultaneously, and the two affect each other, so that the cutting cone of the working part of the tap body 5 is uniform. When the clamping disc 13 rotates forward and reverse, the cutting disc 42 reciprocates, and the tap body 5 is reciprocated. The machining position is accurate, and the precision of the tap body 5 can be further improved.

[0038] like Figure 6 As shown, a sliding table 425 is slidably installed in the sliding groove 411, the internal threaded shaft 412 passes through the sliding table 425, and the two are threadedly connected. An adjustable fixed sheet layer 421 is installed on the upper end of the sliding table 425, a driving motor 422 is fixed on one side of the fixed sheet layer 421, and the cutting disc 42 is arranged on the other side thereof, and the output end of the driving motor 422 is fixed to the cutting disc 42. The driving motor 422 is used to drive the cutting disc 42 to rotate, so that the cutting disc 42 has a grinding effect on the tap body 5. The driving motor 422 can control the rotation speed so that the cutting disc 42 avoids a large squeezing effect on the tap body 5.

[0039] like Figure 6 As shown, both sides of the fixed sheet layer 421 have extension sheets 423 extending outward, and the extension sheets 423 are threadedly connected with fastening bolts 424, and the fastening bolts 424 penetrate the extension sheets 423 downward, and an inlay opening 426 is opened at the upper end of the sliding platform 425, and an inlay shaft 427 is fixed at the lower end of the fixed sheet layer 421, and the inlay opening 426 cooperates with the inlay shaft 427;

[0040] The inlay opening 426 and the inlay shaft 427 are both in an inverted "T" shape. The fastening bolt 424 is rotated to lift the fixed sheet layer 421 upward and fix it. By loosening the fastening bolt 424, the matching condition of the inlay opening 426 and the inlay shaft 427 can be adjusted, so that the fixed sheet layer 421 can be loosened, and the position of the fixed sheet layer 421 can be rotated so that the position of the blade disk 42 can be adjusted. Then, the fastening bolt 424 is tightened to move the fixed sheet layer 421 upward, and the inlay opening 426 and the inlay shaft 427 are abutted against each other to achieve fastening.

[0041] The blade disc 42 is a circular grinding wheel, which processes the cutting cone of the tap body 5 by grinding, and while forming the cutting cone, avoids excessive squeezing force on the tap body 5, so that the tap body 5 remains stable.

[0042] The working principle of the present invention is as follows: the tap body 5 is clamped between the clamping plate 13 and the hydraulic cylinder 33 through the extension and retraction of the hydraulic cylinder 33, and is rotated under the action of the clamping motor 12, and the tap body 5 is also rotated, and the grinding part 4 at the lower end grinds the tap body 5 and moves to grind a cutting cone on the outer side of the tap body 5, and then the hydraulic cylinder 33 is loosened, the tap body 5 is disassembled, and the processing is continued.

[0043] Based on the above, when the tap body 5 is clamped, it is squeezed by the hydraulic cylinder 33 and directly supported in the mounting hole 132. The tap body 5 is supported at both ends, which is convenient for installing and removing the tap body 5. The clamping motor 12 can make the clamping plate 13 and the hydraulic cylinder 33 rotate, which is convenient for processing different positions of the tap body 5. Secondly, the grinding part 4 at the lower end is operated by grinding with the blade disc 42. During the grinding process of the tap body 5, the extrusion force of the blade disc 42 on the tap body 5 does not need to be too large to grind the tap body 5, so that the tap body 5 can be ground with marks. At the same time, the tilting force on the tap body 5 is relatively small. When the tap body 5 is fixed, the clamping of the clamping plate 13 and the hydraulic cylinder 33 can fix the tap body 5. Based on this, the tap body 5 can be conveniently installed and disassembled, and marks can be ground on the tap body 5. There is no need to fix the tap body 5 in multiple directions or structures, thereby improving production efficiency.

[0044] Secondly, the internal threaded shaft 412 is driven to rotate through the set driving gear 134 and the transmission gear 413, so that the moving cutting disc 42 is ground during the rotation of the tap body 5. The two can operate synchronously to ensure that the cutting cone on the tap body 5 is processed. At the same time, the position and proportion of the cutting cone are accurate, thereby improving the quality of the tap body 5.

[0045] It should be noted that, generally, the diameter of the portion of the tap body 5 used for processing the internal threaded hole is large, while the diameter of the shank is relatively small. When the tap body 5 is installed, the cutting disc 42 can be located at the lower end of the shank, so the tap body 5 can be directly clamped between the clamping disc 13 and the hydraulic cylinder 33 for easy operation. When the fastening bolt 424 is moved upward and the fixing sheet layer 421 is moved downward, the inclination angle of the cutting disc 42 can be adjusted to fit the cutting cone of the tap, and can be adjusted for different tap bodies 5.

[0046] Through the driving action of the clamping motor 12, forward and reverse rotation can be achieved, and the tap body 5 can be processed reciprocatingly with higher precision. In addition, the tap body 5 can be replaced in one reciprocating rotation, which facilitates the operation and improves the precision.
