Fastening chamfering cutter

Technical Field

The utility model relates to the technical field of pipe body processing, and more specifically, to a fastening chamfering cutter.

Background Art

A chamfering knife is a tool used to chamfer the edge of a steel pipe. When chamfering a steel pipe, a chamfering machine is used, and a chamfering knife is used on the chamfering machine to process the steel pipe. Not only that, the chamfering knife has a wide range of applications. It is not only suitable for chamfering of ordinary machined parts, but also more suitable for chamfering and deburring of precision and difficult-to-chamfer parts.

A wear-resistant chamfering tool disclosed in a Chinese patent with announcement number CN217492727U has the following technical points: it includes a chamfering head and a spring, a blade is provided on the front end surface of the chamfering head, a support column is installed on the upper end of the chamfering head, and a threaded column is provided on the top of the support column, a first clamping seat is installed on the outside of the support column, and a card is provided on the lower end surface of the first clamping seat, a first fixing ring is installed on the upper end of the first clamping seat, the spring is located on the upper end surface of the first fixing ring, a first mounting hole is provided at the rear end of the chamfering head near the blade, a diamond wear-resistant layer is installed on the surface of the chamfering head, a first connecting ring is provided on the inside of the first clamping seat near the first fixing ring, and a second mounting hole is installed on the surface of the first connecting ring.

Although the above scheme solves the wear resistance problem of the chamfering knife, it does not solve the problem that the chamfering knife will loosen due to constant vibration after long-term use. In the process of processing steel pipes, the steel pipes need to be chamfered to remove sharp edges. At this time, a chamfering machine will be used. The chamfering machine is equipped with a chamfering knife. During the operation, the chamfering knife will constantly contact the steel pipe, which will generate vibration. The screw will rotate in the opposite direction during the vibration, and the vibration will cause the screw on the chamfering knife to loosen. The loosening of the screw will lead to a decrease in the chamfering accuracy, and the surface of the processed product will become rough, resulting in defective products. For this reason, it is necessary to provide a chamfering knife that can make the screw difficult to loosen.

Therefore, new solutions need to be proposed to solve this problem.

DETAILED DESCRIPTION

The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

The fastening chamfering tool, as shown in Figures 1 to 4, includes a chamfering tool rod 1. During the chamfering process, the chamfering tool rod 1 will continuously rotate. A first groove 4 is opened at one end of the chamfering tool rod 1. A clamping tool part 2 is fixedly connected to the inner bottom surface of the first groove 4. The clamping tool part 2 is used to clamp the milling cutter. A fastener 3 is fixedly connected to the top surface of the clamping tool part 2. The fastener 3 is a hexagon socket screw. The top surfaces of the clamping tool part 2 and the fastener 3 are provided with an indicating portion indicating that the fastener 3 is rotated to a suitable position. If the fastener 3 rotates under the action of vibration, the indicating portion will It can be seen that the rotation of the fastener 3 is caused by looseness, and the relevant staff can understand whether the fastener 3 is loose through the indicator part. A second groove 5 is opened on the bottom surface of the clamping knife 2. The cross-section of the second groove 5 is circular. A shockproof part is fixedly connected to the inner bottom surface of the second groove 5. The shockproof part is used to reduce the vibration transmitted to the fastener 3. The shockproof part is fixedly connected to the inner bottom surface of the second groove 5. The fastener 3 passes through the shockproof part, so the shockproof part will wrap the fastener 3, and the vibration will be transmitted to the shockproof part first, and then to the fastener 3.

As shown in Figures 1 to 4, the shockproof part includes a shock-absorbing layer 6 and an elastic layer 7. The main material of the shock-absorbing layer 6 is sponge, and the material of the elastic layer 7 is rubber. The top surface of the elastic layer 7 is provided with a third groove 14, and the bottom end of the fastener 3 is located in the third groove 14. The cross-section of the third groove 14 is circular, and a thread 13 is provided on the outer wall of the fastener 3. The fastener 3 is fixed in the clamping tool 2 through the thread 13. The fastener 3 makes the clamping tool 2 fixedly connected to the chamfering tool rod 1, and the inner peripheral wall of the third groove 14 is provided with a thread that is connected to the thread The screw groove 15 matches the groove 13, and the screw groove 15 cooperates with the thread 13, so as to increase the friction between the thread 13 and the elastic layer 7. The shock-absorbing layer 6 is fixedly connected to the outer wall of the elastic layer 7, and the shock-absorbing layer 6 is adhered to the outer side of the elastic layer 7 by gluing. The shock-absorbing layer 6 is against the inner circumferential wall of the second groove 5. Because both the elastic layer 7 and the shock-absorbing layer 6 have elastic deformation properties, and because of the material, the sponge is softer than rubber, so under the extrusion of the elastic layer 7, the shock-absorbing layer 6 is against the inner circumferential wall of the second groove 5.

As shown in FIGS. 1, 2 and 5, the indicating portion includes a first indicating member 8 and a second indicating member 9. The first indicating member 8 is a groove with a triangular cross section, and the second indicating member 9 is a groove with a rectangular cross section. The first indicating member 8 is provided on the top surface of the fastener 3, and the second indicating member 9 is provided on the top surface of the clamping knife member 2. When the fastener 3 is tightened, the first indicating member 8 points to the second indicating member 9. When the first indicating member 8 does not point to the second indicating member 9, the fastener 3 is in a loose state and needs to be tightened with a hexagonal wrench. The indicating portion also includes a protrusion 10 And the inclined groove 11, the protrusion 10 is fixedly connected to the outer side wall of the fastener 3, the protrusion 10 and the fastener 3 are integrally formed, the protrusion 10 is hemispherical, the inclined groove 11 is opened on the top surface of the clamping knife part 2, and the fastener 3 will eventually be screwed into the inclined groove 11 during the process of screwing into the third groove 14. The inclined groove 11 is provided with a guide surface 12 for the protrusion 10 to be screwed into. Under the action of vibration, the fastener 3 will be screwed out in the opposite direction. During the screwing out process, the protrusion 10 will resist the guide surface 12, and the guide surface 12 will generate a force to prevent the fastener 3 from being screwed out.

Working principle: when the clamping tool 2 is installed on the chamfering tool rod 1, the fastener 3 needs to be screwed into the clamping tool 2 with a hexagonal wrench. When the bottom end of the fastener 3 is screwed into the third groove 14, the thread 13 cooperates with the screw groove 15, so that the friction between the fastener 3 and the elastic member increases. At this time, a greater force is required to screw the fastener 3 into the third groove 14. When the fastener 3 is completely screwed through the third groove 14, the first indicator 8 and the second indicator 9 are located in the same direction, and the protrusion 10 is screwed into the inclined groove 11; when the chamfering tool rod 1 starts to rotate, the blade on the clamping tool 2 will contact the steel pipe, thereby continuously generating vibrations. The vibrations will first be transmitted to the shock-absorbing layer 6, and the shock-absorbing layer 6 will reduce part of the vibrations. The vibrations continue to be transmitted to the elastic layer 7. The elastic layer 7 has the function of increasing the friction between it and the fastener 3, and at the same time, it also has the function of reducing vibrations. After the clamping tool 2 has been used for a long time, the relevant staff can judge whether the fastener 3 is tightened according to the direction indicated by the first indicator 8.
