example one

As shown in fig. 1, in order to machine different shapes and different parts of the polymer tube bar, three different-shaped machining tools 56 are provided in this embodiment. The three differently shaped cutters 56 are capable of cutting the exterior, interior and top of the bar as required by the particular operating conditions. Because the tube and bar are cut by rotation in the cutting process, the cut shape of the tube and bar is annular. In addition, since the tube and bar are only rotated and not moved during the cutting process, the cutting of different parts of the tube and bar is realized by moving the cutter 56.

For accurate position of moving the tool 56, a transverse translation mechanism and a longitudinal translation mechanism are provided in this embodiment, the transverse translation mechanism includes a bottom plate 31 and a transverse guide rail 32, the bearing plate 51 is clamped on the transverse guide rail 32, the transverse guide rail 32 is installed on the bottom plate 31, the servo motor is connected with the bearing plate 51, the bearing plate 51 is driven by the servo motor to move along the transverse guide rail 32, and thus the bearing plate 51 drives the three tools 56 to move transversely together. The longitudinal translation mechanism comprises a base 21 and a longitudinal guide rail 22, a bottom plate 31 is clamped on the longitudinal guide rail 22, the longitudinal guide rail 22 is installed on the base 21, a servo motor is connected with the bottom plate 31, the bottom plate 31 is driven by the servo motor to move along the longitudinal guide rail 22, and therefore the bottom plate 31 drives the bearing plate 51 and the three cutters 56 to move longitudinally together. In order to prevent the components in fig. 1 from shielding each other and affecting the clear representation of the components in the figure, the servo motor and the connection structure thereof are not shown in fig. 1.

As shown in fig. 1 and fig. 2, in order to prevent filiform scraps generated during the machining of the polymer tube and bar material from being wound around the periphery of the tube and bar material, or wound around the cutter 56, or falling into the inner hole of the tube and bar material, thereby affecting the normal machining of the next process step, a scrap blowing mechanism and a scrap sucking mechanism are provided in this embodiment.

Three fixing seats 52 and three corresponding inner positioning blocks 55 are mounted on the bearing plate 51, and the inner positioning blocks 55 are bent into an L shape, so that the two bent plates are perpendicular to each other. One end of the inner positioning block 55 is fixed to the carrier plate 51, and the inner positioning blocks 55 fixed to the carrier plate 51 are distributed in a horizontal direction. The other end of the inner positioning block 55 extends out of the bearing plate 51, the inner positioning block 55 extending out of the other end of the bearing plate 51 is vertically erected, and a through inner air hole is formed at one end of the inner positioning block 55 extending out of the bearing plate 51. A C-shaped frame 33 is installed on the outer side of the bottom plate 31, the C-shaped frame 33 has three sides, and the C-shaped frame 33 is distributed in the horizontal direction. An outer positioning block 34 is installed at a middle position of the second side of the frame 33, and the outer positioning block 34 is perpendicular to the second side of the frame 33. The upper end of the outer positioning block 34 is provided with a through outer air hole, and the movable bearing plate 51 can enable the outer positioning block 34 to be attached to any one of the three inner positioning blocks 55. Since the height of the outer air hole is the same as or slightly different from the height of the three inner air holes, the inner air holes can communicate with the outer air holes when the inner positioning block 55 and the outer positioning block 34 are attached together.

The scrap suction mechanism comprises an inner suction pipe 53 and an outer suction pipe 42, in this embodiment, in order to facilitate the installation and fixation of the inner suction pipe 53 on the inner positioning block 55, a tubular elastic rubber suction pipe joint 54 is firstly vulcanized and fixed on the inner positioning block 55, and then one end of the inner suction pipe 53 is installed in the suction pipe joint 54 in an interference fit manner. Thus, one end of the inner air suction pipe 53 is installed on the inner positioning block 55, and the inner air suction pipe 53 is communicated with the inner air hole on the inner positioning block 55. One end of the outer air suction pipe 42 is installed and fixed on the outer positioning block 34, and the outer air suction pipe 42 is communicated with the outer air hole on the outer positioning block 34.

In this embodiment, one end of the outer suction pipe 42 is connected to the outer positioning block 34, and the other end of the outer suction pipe 42 is connected to a suction device, which is preferably an industrial vacuum cleaner. When the cutter 56 moves to the inside of the pipe and bar material to cut the inside of the pipe and bar material, chips are produced and fall into the pipe and bar material at any time during the cutting process. At this time, the industrial vacuum cleaner is started to vacuumize the outer suction pipe 42, and air and debris in the inner suction pipe 53 communicating with the outer suction pipe 42 are sucked into the outer suction pipe 42 by the vacuum negative pressure of the outer suction pipe 42. In order to clean the debris in the outer air suction pipe 42 in time, a sealed valve can be arranged at the bottom of the other end of the outer air suction pipe 42, and the valve can be opened after air suction is completed, so that the debris in the outer air suction pipe 42 falls into a garbage can below the valve.

As shown in fig. 1, 2 and 3, in addition, in order to prevent the small gap between the outer positioning block 34 and the inner positioning block 55 from generating air leakage, an elastic gasket 35 may be disposed between the outer positioning block 34 and the inner positioning block 55, and an air hole 351 is formed in the middle of the gasket 35, so that the air hole 351 is communicated with both the outer air hole and the inner air hole. When vacuum pumping is performed, because the outer positioning block 34 and the inner positioning block 55 are both made of metal, under the adsorption action of vacuum negative pressure, because the gap between the outer positioning block 34 and the inner positioning block 55 is very small, the outer positioning block 34 and the inner positioning block 55 can be close to each other until being attached together, and the elastic gasket 35 can play a role in sealing and preventing air leakage.

The other end of each internal air suction pipe 53 penetrates through and extends out of a fixed seat 52, and the fixed seat 52 can play a role in adjusting the height of the internal air suction pipe 53 and supporting the internal air suction pipe 53. And the three inner air suction pipes 53 extend out of the top end of the fixed seat 52 for cutting, a section of bearing head 531 is cut at the top end of the inner air suction pipe 53, the section of the bearing head 531 is in an arc shape, and the cutter 56 is installed on the bearing head 531. The scrap blowing mechanism comprises an air blowing pipe 41 and an air compressor, one ends of the three air blowing pipes 41 are combined together to form one air blowing pipe 41, and the top end of the air blowing pipe 41 is connected to the air compressor. The air compressor is started to blow air flowing at high speed into the air blowing pipes 41, and the air flowing at high speed is respectively sprayed out from the air outlet ends of the three air blowing pipes 41. The air outlet port of the air blowing pipe 41 is arranged outside the cutter 56, so that the direction of the air flow can be adjusted, and the direction of the air flow is directly opposite to the part processed by the cutter 56. Therefore, when the cutter 56 cuts the outside of the pipe or rod, the high-speed air flow ejected from the air blowing pipe 41 blows the chips generated by cutting the outside of the pipe or rod onto the ground.

When the tip of the tube or bar is machined, chips are generated on the outside and inside of the tube or bar. Therefore, the scrap blowing mechanism and the scrap sucking mechanism are both required to be started at the moment, and the scrap treatment is carried out on the outer portion and the inner portion of the pipe bar simultaneously. The three cutters 56 in this embodiment, which are used for machining the outside of the pipe and bar, which are used for machining the top end of the pipe and bar, and what shape of the pipe and bar is cut, can be adjusted according to specific conditions.

It will be apparent that modifications and variations are possible without departing from the principles of the invention.
