Example 1:

the cutter angle adjusting mechanism for the pipeline beveling machine as shown in figure 1 comprises a cutter mounting mechanism 2, a cutter angle adjusting mechanism and a cutter angle adjusting mechanism, wherein the cutter mounting mechanism 2 is used for mounting a cutter 4 and enabling the cutter 4 to be close to or far away from the axis of a pipeline along the radial direction of the pipeline; the angle adjusting bracket 3 is detachably connected with the cutter mounting mechanism 2 and enables the cutter mounting mechanism 2 to rotate so as to change the included angle between the cutting edge 402 of the cutter 4 and the axis of the pipeline; the center of the rotating base 1 is provided with a through hole for a pipeline to pass through, and the angle adjusting bracket 3 is fixedly installed and rotates around the axis of the pipeline.

The working principle is as follows:

this application uses rotating base 1 as the basis, and rotating base 1 goes up fixed angle adjusting bracket 3, connects cutter installation mechanism 2 on the angle adjusting bracket 3, sets up cutter 4 again on cutter installation mechanism 2, and then rotating base 1's rotation actually makes cutter 4 rotate around the pipeline axis, and the action that cooperation cutter 4 is close to the pipeline axis on cutter installation mechanism 2 for the processing of groove is accomplished to cutter 4. Specifically, before machining, a cutting edge 402 of the tool 4 is firstly contacted with the outer edge of the end face of the pipeline, which can be regarded as the zero position of the tool 4, then the rotating base 1 starts to rotate, and simultaneously the tool 4 moves relative to the tool mounting mechanism 2 and moves towards the direction close to the center of the pipeline along the radial line of the pipeline, after each rotation of the rotating base 1 for one circle or two circles, the tool 4 approaches a point towards the center of the pipeline until the requirement of the depth of the groove is met, the movement of the tool 4 approaching the center of the pipeline and the rotation of the rotating base 1 are stopped, and the tool 4 moves towards the direction far away from the center of the pipeline and retreats to the original zero position, thereby completing the groove machining.

Because the cutting tool 4 includes two main portions, a shank portion and a cutting portion, the shank portion is used for fixing the cutting tool 4, and in order to avoid the influence of the shank portion on the cutting portion during operation, a certain included angle is formed between the cutting portion and the shank portion, which is mainly embodied in the included angle between the cutting edge 402 and the shank portion. The cutting edge 402 is a portion directly contacting with the workpiece, the cutting edge 402 is an intersection line between the rake face and two faces of the main rear face, and in order to ensure the smoothness of the machined surface of the workpiece, the rake face and the main rear face form an acute angle, so that the contact area between the main rear face and the workpiece is reduced. The end of the cutting edge 402 is the cutting edge 401 and is also one end of the tool 4. Because behind the groove preparation, the surface of groove and cutting edge 402 accomplish the coincidence, consequently, the contained angle of cutting edge 402 and pipeline axis equals the contained angle of groove crest line and pipeline axis, and the cooperation of angle modulation support 3 in this application and cutter installation mechanism 2 is then in order to adjust the contained angle of cutting edge 402 and pipeline axis. Specifically, the angle of the cutting edge 402 with respect to the pipe axis in the direction shown in fig. 1 is viewed from above, and thus the rotation of the tool mounting mechanism 2 and the tool 4 is about a vertical line. It should be noted that the rotation of the tool mounting mechanism 2 inevitably causes the position of the tool 4 relative to the pipe to change, for example, in the case of not providing the arc-shaped guide rail 301, the rotation of the tool mounting mechanism 2 in place may cause the distance between the two tools 4 on the rotating disc to be shortened, so that the zero point position of the tool 4 needs to be readjusted, and in the case of exceeding the zero point adjustment range, the pipes with the same diameter cannot be machined with different bevel angles.

It should be noted that the rotating base 1 in the adjusting mechanism provided in this embodiment is a part rotatably mounted on the beveling machine, and the rotating base 1 is connected to the driving mechanism in the beveling machine in a transmission manner, as shown in fig. 1, an example of the transmission manner is shown, that is, the periphery of the rotating base is provided with transmission teeth, and the transmission manner is connected to the power source in the beveling machine in a transmission manner by matching of gears, which is well known in the art and will not be described in detail herein.

Example 2:

this example is further optimized and defined based on example 1.

As shown in fig. 1 and 5, the angle adjusting bracket 3 includes an arc guide rail 301 fixedly connected to the rotating base 1, a circle center of the arc guide rail 301 coincides with the knife tip 401, and a rotation track of the angle adjusting bracket 3 is adapted to the arc guide rail 301. Cutter installation mechanism 2 is connected with arc guide rail 301 through coupling mechanism, coupling mechanism includes the mount pad 303 with 2 fixed connection of cutter installation mechanism, arc guide rail 301 surface adaptation pitch arc camber is equipped with the spout 302 that supplies mount pad 303 to run through arc guide rail 301, spout 302 surface is the cockscomb structure, rotate the cover on the mount pad 303 and be equipped with the gear 304 with spout 302 sawtooth engaged with, the one side that cutter installation mechanism 2 was kept away from to arc guide rail 301 is equipped with and passes through screw-thread fit and with the knob 305 of arc guide rail 301 surface butt with fixed cutter installation mechanism 2 with mount pad 303.

When the angle of the tool 4 needs to be adjusted, the knob 305 is rotated a little from the mounting base 303 so that the knob 305 does not abut against the surface of the arc-shaped guide rail 301, then the position of the tool nose 401 is kept fixed, the tool mounting mechanism 2 is rotated around the tool nose 401, the gear 304 rotates relative to the mounting base 303 when the tool mounting mechanism 2 rotates and keeps a meshing state with the saw teeth in the sliding groove 302, and after the adjustment is completed, the knob 305 is screwed into the mounting base 303, and the knob 305 abuts against the surface of the arc-shaped guide rail 301 tightly.

It should be noted that the adjustment of the angle of the tool 4 can be realized only by rotating around the vertical line as the axis, the rotation of the tool mounting mechanism 2 inevitably causes the rotation of the tool 4, the center of the arc-shaped guide rail 301 in this embodiment coincides with the knife tip 401, when the angle of the tool 4 is adjusted, the position of the knife tip 401 is preferably kept unchanged, the tool mounting mechanism 2 rotates around the knife tip 401, and during the rotation, the mounting base 303 slides along the sliding groove 302 of the arc-shaped guide rail 301. The centering of the cutting edge 401 is to avoid the change of the contact point of the cutter 4 with the outer edge of the pipeline, so that the fixed position of the pipeline is not required to be readjusted to ensure the depth of the groove.

Example 3:

in this embodiment, further optimization and limitation are performed on the basis of embodiment 2.

As shown in fig. 4, the tool mounting mechanism 2 includes a housing 201 fixedly connected to a mounting seat 303, a screw is rotatably mounted in the housing 201, a nut seat is slidably disposed on the screw, and the nut seat is fixedly connected to a tool rack 202 disposed outside the housing 201 and used for mounting a tool 4; one end of the screw rod is connected with a driving mechanism.

Example 4:

this embodiment is further optimized and defined based on any one of the above embodiments.

As shown in fig. 2 and 5, the surface of the arc-shaped guide rail 301 is provided with angle scale lines distributed along the edge of the sliding groove 302, and the angle scale lines correspond to the angle of the edge of the casing 201 rotating around the knife tip 401.

The arrangement of the scale lines increases the accuracy of the rotation angle of the tool mounting mechanism 2, and the preferable arrangement mode is that when the sawtooth in the sliding groove 302 is matched with the gear 304 to enable the gear 304 to rotate by one sawtooth every time, the tool mounting mechanism 2 rotates by one degree by taking the tool tip 401 as the center of a circle, because the position of the tool tip 401 is not hinged with any component, the rotation center of the tool mounting mechanism 2 is difficult to guarantee, and the arrangement of the angle scale lines increases the reference of the rotation angle of the tool mounting mechanism 2. For example, if the initial position of the tool mounting mechanism 2 is a position that coincides with the angle scale line of 30 degrees and adjustment to 45 degrees is required, if the center of the cutting edge 401 cannot be ensured, the number of teeth that the gear 304 rotates is controlled to correspond to 15 degrees, and then the position of the gear 304 is held fixed, and the housing 201 and the mounting base 303 are rotated relative to the gear 304 until the edge of the housing 201 coincides with the angle scale line of 45 degrees, which is also the edge that originally coincides with the 30 degree scale line. In addition, as shown in the figure, angle scale marks can be arranged on the arc-shaped guide rail 301 along two arc-shaped edges of the sliding groove 302, and in order to enable the scale marks on the two arc-shaped edges to correspond to two different edges of the shell 201 respectively, the two angle scale marks are slightly staggered.

Preferably, the angle adjusting mechanism enables the angle adjusting range of the cutter 4 to be 0-90 degrees. Fig. 1 shows an example of the included angle between the cutting edge 402 of the cutter 4 and the pipeline axis being 0 °, which corresponds to the 0 ° scale mark on the arc-shaped guide rail 301 for the convenience of illustration, and fig. 3 shows a position schematic diagram of the cutter 4 after rotating a certain angle.

The above description is only a preferred embodiment of the present application and is not intended to limit the present application, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
