Description

Technical Field

[0001] This utility model relates to the field of spiral cutting tap technology, and in particular to a high-performance general-purpose spiral cutting tap. Background Technology

[0002] A spiral cutting tap, also known as a spiral tap or spiral groove tap, is a tool specifically designed for making and repairing threads.

[0003] Utility model patent No. 202022768859.0 discloses a high-performance spiral forward-tilt tap, belonging to the field of tap technology. It solves the problem of poor performance of straight flute forward-tilt taps in existing technologies. This high-performance spiral forward-tilt tap includes a tap body with a fixed square head. The front end of the tap body is provided with a tap working part for machining the workpiece. A transition section is provided between the fixed square head and the tap working part. The tap working part has several threaded cutting teeth, which, together with the tap working part on the tap body, form several spiral grooves. A groove for coolant flow is formed on the fixed square head along the shaft direction. Several holes communicating with the spiral grooves are formed on the inner walls of the four grooves. The spiral grooves and the central axis of the tap body form an angle α.

[0004] However, the above-mentioned devices still have some drawbacks in actual use. The most obvious one is that the existing spiral cutting taps tend to generate a lot of heat during the machining process, which causes the tap temperature to rise. After long-term use, the tap is prone to deformation and damage. When the existing tap is damaged, the entire tap needs to be replaced, and the undamaged parts, such as the tap shank at the top of the tap, will also be replaced, which easily leads to a waste of resources.

[0005] Therefore, it is necessary to invent a high-performance universal spiral cutting tap to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a high-performance universal spiral cutting tap. A tap shank is fixedly connected to the bottom end of the tap body.

[0034] like Figures 1-3 As shown, a high-performance general-purpose spiral cutting tap disclosed herein may include a tap body 1, a plurality of cutting edges 11 uniformly arranged on the inner side of the tap body 1, a cutting cone 12 provided at the top end of the tap body 1, a chip removal groove 13 provided at the bottom end of the tap body 1, the angle between the cutting cone 12 and the tap body 1 is 60°, the angle of the cutting edge is in the range of 120°-160°, and the chip removal groove 13 is connected to the cutting edge.

[0035] The bottom end of the tap body 1 is fixedly connected to the tap shank 2, the bottom end of the tap shank 2 is provided with a connecting rod 4, the outside of the connecting rod 4 is provided with a screw 3, and the bottom end of the connecting rod 4 is provided with a mounting part 5.

[0036] A sealing ring 21 is fixedly connected to the bottom end of the cone shank 2, a fixing block 6 is fixedly connected to the bottom end of the sealing ring 21, and a snap-fit ​​block 62 is fixedly connected to both sides of the bottom end of the fixing block 6.

[0037] The inner side of the connecting rod 4 is provided with a placement groove 42, the bottom end of the placement groove 42 is provided with a snap-fit ​​groove 43, the fixing block 6 is provided on the inner side of the placement groove 42, and the snap-fit ​​block 62 is provided on the inner side of the snap-fit ​​groove 43.

[0038] Therefore, by fixing a sealing ring 21 to the bottom end of the taper shank 2, fixing a fixing block 6 to the bottom end of the sealing ring 21, and fixing a snap-fit ​​block 62 to both sides of the bottom end of the fixing block 6, the fixing block 6 is located inside the placement groove 42, and the snap-fit ​​block 62 is located inside the snap-fit ​​groove 43, so that the taper shank 2 and the connecting rod 4 can be fixedly connected. At the same time, when the connecting rod 4 rotates, the fixing block 6 and the snap-fit ​​block 62 snap into the inside of the connecting rod 4, thereby effectively driving the tap body 1 to rotate. The mounting part 5 has the same structure as described above and can be quickly replaced in the same way, that is, the tap body 1 and the mounting part 5 can be replaced effectively, which effectively improves the performance of use.

[0039] like Figure 1 and Figure 2 As shown, in a preferred embodiment, a hidden groove 41 is provided in the middle of the connecting rod 4, the screw 3 is provided inside the hidden groove 41, and a screw hole 61 is provided inside the fixing block 6, and the screw 3 is threaded to the inside of the screw hole 61.

[0040] Therefore, by setting the hidden groove 41, the screw 3 can be effectively hidden. By setting the screw 3, the screw 3 is threaded to the inside of the screw hole 61, thereby effectively fixing the fixing block 6 to the inside of the connecting rod 4.

[0041] like Figure 3 As shown in this disclosure, threaded grooves 63 are provided on both sides of the fixing block 6, and mounting block 7 is threadedly connected to the inner side of the threaded groove 63. A connecting block 74 is fixedly connected to one side of the mounting block 7, and the connecting block 74 is located on the outer side of the fixing block 6.

[0042] Therefore, by setting the threaded groove 63, the outer side of the mounting block 7 is provided with external threads, which makes it easy to thread the mounting block 7 to be fixedly connected to the threaded groove 63. By setting the connecting block 74, the connecting block 74 can effectively drive the mounting block 7 to rotate.

[0044] Therefore, by setting slider 72, slider 72 is limited to sliding inside the mounting block 7, and spring 71 is set on one side of slider 72. In actual use, spring 71 presses slider 72 tightly on one side of mounting block 7, and causes limiting block 73 to be pressed on the outside of mounting block 7. Pressing limiting block 73 will cause limiting block 73 to retract to the inside of mounting block 7, and spring 71 will be compressed.

[0045] like Figure 3As shown in this disclosure, through holes 44 are provided on both sides of the connecting rod 4, and the limiting block 73 is disposed inside the through hole 44.

[0046] Therefore, by setting the through hole 44, the limiting block 73 can be set inside the through hole 44. In actual use, press the limiting blocks 73 on both sides so that the limiting blocks 73 are retracted into the inner side of the mounting block 7, thereby facilitating the setting of the fixing block 6 inside the placement groove 42, so that the limiting block 73 slides inside the placement groove 42 and finally locks into the inner side of the through hole 44. When the fixing block 6 needs to be removed, press the limiting block 73 into the inner side of the mounting block 7 from the through hole 44, pull the taper handle 2 to drive the fixing block 6 to slide out from the inner side of the connecting rod 4, which facilitates the replacement of the tap body 1.

[0047] In actual use, the tap body 1, connecting rod 4 and mounting part 5 can be used normally. After a period of use, if the tap body 1 is damaged due to high temperature deformation, the tap body 1 should be replaced.

[0048] When replacing, remove screw 3 from the inside of the hidden groove 41, press the limiting block 73 into the inside of the mounting block 7 through the through hole 44, pull the taper handle 2 to drive the fixing block 6 to slide out from the inside of the connecting rod 4, so as to facilitate the replacement of the tap body 1.

[0049] Replace the tap body 1 with a new one, press the limiting blocks 73 on both sides so that the limiting blocks 73 are retracted into the inner side of the mounting block 7, so that the fixing block 6 can be set in the inner side of the placement groove 42. The limiting block 73 slides in the inner side of the placement groove 42 and finally snaps into the inner side of the through hole 44. Then, use the screw 3 to thread it into the inner side of the screw hole 61, so as to effectively fix the fixing block 6 to the inner side of the connecting rod 4.

[0050] Those skilled in the art should understand that the above embodiments are merely for illustrating the present disclosure and are not intended to limit the scope of the disclosure.
