DETAILED DESCRIPTION

[0028] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0029] like Figure 1 and Figure 2 As shown, an embodiment of the utility model provides an internal expansion type flange A end face processing machine for processing the end face of flange A; it includes: a frame 1, the frame 1 has a locking surface 11 and a pressing surface 12 arranged opposite to each other along a first direction; the tool holder feeding mechanism 2 is arranged on the frame 1 in an adjustable position along a second direction, for making the cutter 23 on the tool holder feeding mechanism 2 contact with the flange A, and the first direction is perpendicular to the second direction; the adjustment component 3 is arranged on the frame 1, for adjusting the contact between different cutting surfaces of the cutter 23 and the flange A; the driving mechanism 4 is arranged on one side of the pressing surface 12; the base structure 5 corresponds to the locking surface 11 of the frame 1, and the base structure 5 is used to install the flange A.

[0030] It should be noted that the internal expansion flange A end surface processing machine includes a frame 1, a tool holder feeding mechanism 2, an adjustment component 3, a driving mechanism 4 and a base structure 5, wherein the frame 1 has a locking surface 11 and a pressing surface 12, and the locking surface 11 and the pressing surface 12 are arranged relative to each other along a first direction. A tool holder feeding mechanism 2 is provided on the frame 1, and the tool holder feeding mechanism 2 can move relative to the frame 1 along a second direction, and the first direction is perpendicular to the second direction. A cutter 23 is provided on the tool holder feeding mechanism 2. In order to facilitate the adjustment of the direction of the cutter 23, an adjustment component 3 provided on the frame 1 is used to adjust the cutter 23. When it is necessary to process the end face of flange A to different degrees of roughness, the cutter 23 is adjusted by the action of the adjustment component 3. When it is necessary to fine-process the end face of flange A, the adjustment component 3 is moved to select the cutting surface that the cutter 23 can perform fine-processing; when it is necessary to rough-process the end face of flange A, the adjustment component 3 is moved to select the cutting surface that the cutter 23 can perform rough-processing; the action of the adjustment component 3 is used to quickly adjust the cutter 23 without replacing the cutter 23 on the tool holder feed mechanism 2, thereby realizing the use of one cutter 23 to achieve the processing of different degrees of roughness of the end face of flange A, thereby improving efficiency. Along the first direction, a base structure 5 is provided at the bottom of the pressing surface 12 of the frame 1. The base structure 5 is used to install the flange A, fix the flange A relative to the fixed structure, and then fix the base structure 5 relative to the locking surface 11 of the frame 1. In this way, the relative position of the end face of flange A relative to the cutter 23 on the tool holder feed mechanism 2 and the end face of flange A can be determined. When the end face of flange A needs to be processed, the tool holder feed mechanism 2 is controlled by the driving mechanism 4 to rotate relative to the flange A, thereby realizing the processing of the end face of flange A by the cutter 23 on the tool holder feed mechanism 2.

[0031] When it is necessary to groove or perform other operations on the end face of flange A, the tool holder feed mechanism 2 only needs to be replaced as needed, that is, the cutter 23 on the tool holder feed mechanism 2 is replaced according to the function, so that the end face of flange A can be processed using the cutter 23. Specifically, the tool holder feed mechanism 2 is mounted on the frame 1 by means of bolts or the like.

[0032] In some specific embodiments, the internal expansion flange A end-facing machine provided by the present invention further includes a transmission assembly 6, which is disposed on the machine frame 1 and is in driving connection with the tool holder feed mechanism 2. The tool holder feed mechanism 2 includes a mounting seat 21 and a tool holder 22 mounted on the mounting seat 21; the mounting seat 21 is slidably disposed on the machine frame 1 and is in driving connection with the transmission assembly 6; the tool holder 22 is rotatably disposed on the mounting seat 21 and is detachably connected to the cutter 23.

[0033] For ease of understanding, the movement process of the tool holder feeding mechanism 2 is explained. The transmission assembly 6 arranged on the frame 1 specifically includes a screw 61 and a handle 62 that is transmission-connected to one end of the screw 61. When the handle 62 rotates, it drives the screw 61 to rotate. The mounting seat 21 in the tool holder feeding mechanism 2 is transmission-connected to the other end of the screw 61, that is, when the handle 62 is rotated, the handle 62 drives the screw 61 to rotate, and the screw 61 drives the mounting seat 21 to move, thereby realizing the movement of the mounting seat 21 along the second direction.

[0034] For example, the tool holder feed mechanism 2 can feed the cutter at any angle. To adjust the cutter's angle, loosen the two locking screws, rotate the mounting base 21 to the desired angle, and then tighten. Of course, depending on the shape or function of the cutter, a different mounting base 21 can be selected to match it. The mounting base 21 can be shaped, for example, V-shaped, which effectively saves space.

[0035] Of course, in order to ensure the smooth movement of the tool holder feeding mechanism 2 and ensure the effect of the cutting knife 23 on the tool holder feeding mechanism 2 on the end face processing of the flange A, the frame 1 has a guide groove 13. The limiting effect of the guide groove 13 improves the smooth movement of the tool holder feeding mechanism 2. The extension line direction of the guide groove 13 is parallel to the first direction; the mounting seat 21 is slidably arranged in the guide groove 13.

[0036] In some specific embodiments, such as Figure 3 As shown, the base structure 5 also includes: a base 51 and an installation locking assembly 52; the base 51 is sleeved with the flange A, the flange A has a first installation port, and the base 51 has a second installation port. When the base 51 is located in the installation port, the first installation port and the second installation port are coaxially arranged, and the installation locking assembly 52 is located in the second installation port and is connected to the base 51, and is used to lock the base 51 and the flange A relative to each other.

[0037] For ease of understanding, the first mounting opening of flange A is circular. A base 51 is disposed within the first mounting opening, located in the center of flange A, for embedded mounting with flange A. A mounting locking assembly 52 is provided within the base 51, which locks the base 51 to flange A. The mounting locking assembly 52 is screwed into the correct base 51, ensuring that the diameter of the base 51 is approximately 6 mm smaller than the actual diameter of the first mounting opening of flange A to be machined.

[0038] like Figure 3 As shown, please refer to Figure 4The mounting and locking assembly 52 includes an adjustment plate 521 and a mounting claw 522. The adjustment plate 521 is located in the second mounting opening. One end of the mounting claw 522 is detachably connected to the adjustment plate 521, that is, one end of the mounting claw 522 is connected to the adjustment plate 521 via a second connector; the other end is detachably connected to the base 51, that is, the other end is connected to the base 51 via a first connector. The first and second connectors can be bolts and nuts, etc., and there is no specific limitation here, as long as they can achieve a connection.

[0039] When there are four mounting claws 522, the four mounting claws 522 are symmetrically arranged relative to the adjustment plate 521; the four mounting claws 522 are symmetrically arranged, that is, the angle between any two adjacent mounting claws 522 is 90°; of course, the number of mounting claws 522 can be an odd number or an even number, for example, there can be three or five mounting claws 522, etc. Of course, no matter how the number of mounting claws 522 is set, the angle between any two adjacent mounting claws 522 is equal. Such a setting can ensure the stability of the adjustment plate 521 and the flange A.

[0040] In addition, the mounting and locking assembly 52 also includes a telescopic member 523 located at the second mounting opening. One end of the telescopic member 523 is connected to the adjustment plate 521, and the other end can be telescopically moved toward or away from the base 51. When the base 51 is inserted into the first mounting opening of the flange A, there is a certain gap between the two, and the base 51 is not completely locked. At this time, the telescopic member 523 extends and provides thrust to the base 51, tightly fitting the base 51 to the flange A.

[0041] Continue to refer Figure 4 The mounting claw 522 has a plurality of connection holes 5221 arranged along its length. A matching base 51 can be selected based on the size of the flange A, and a matching mounting and locking assembly 52 can be selected for the base 51. However, the size of the base 51 and the adjustment plate 521 in the mounting and locking assembly 52 may differ significantly. By selecting connection holes 5221 at different locations, the base 51 and the adjustment plate 521 can be matched.

[0042] For example, the driving mechanism 4 includes a motor or a motor, and the motor and the motor structure can be selected according to needs.

[0043] Obviously, those skilled in the art may make various changes and modifications to the embodiments of the present invention without departing from the spirit and scope of the present invention. Thus, if such modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is intended to include such modifications and variations.
