Description

Technical Field

[0001] The invention relates to the technical field of parts processing, and in particular to a tubular parts inner hole honing device and a honing method thereof. Background Art

[0002] Honing is a finishing process of the finished surface with the honing strips embedded in the honing head. The contact area between honing and the hole surface is large, and the processing efficiency is high. During honing, the workpiece is installed on the honing table or in the fixture, and the honing head with several honing strips is inserted into the processed hole. The machine tool spindle drives it to rotate and make axial reciprocating motion. The honing strips contact the hole wall with a certain pressure, and a very thin layer of metal can be cut off.

[0003] The existing honing equipment mainly uses threaded rods and moving blocks to drive the pipe fittings to move, so that the honing mechanism moves inside the pipe fittings. However, in the actual operation process, due to the long length of some pipe fittings, if the inner wall of the pipe fittings is to be completely honed, a longer threaded rod needs to be set to drive the pipe fittings, which makes the occupied area of ​​the entire device larger; and in order to achieve the honing effect on the inner hole of the pipe fitting, the existing honing structure needs a longer time to perform the honing work, and the long operation time affects the honing efficiency of the pipe fittings.

[0018] The present invention also discloses a honing method of a tubular part inner hole honing device, comprising the following steps:

[0019] S1: Place the pipe fitting on the lower clamp seat, and rotate the threaded rod to make the connecting plate drive the upper clamp seat to move downward, and the upper clamp seat cooperates with the lower clamp seat to clamp and position the pipe fitting;

[0020] S2: Then, according to the size of the pipe fitting, the screw is rotated to adjust the distance between the abutment plate and the fixed plate, so that the ball on the surface of the abutment plate abuts against the inner wall of the pipe fitting, and the adjusting tube is rotated at the same time to move the adjusting tube axially relative to the connecting tube, thereby adjusting the position of the tapered block, so that when the subsequent tapered block abuts against the wedge block, the wedge block drives the honing stick to move the maximum distance and can abut against the inner wall of the pipe fitting;

[0021] S3: Control the operation of the hydraulic pump and drive motor:

[0022] The hydraulic pump introduces the hydraulic oil into the hydraulic pipe through the pipeline. The piston block in the hydraulic pipe moves under the force and drives the flexible member to move to the outside of the hydraulic pipe. The flexible member moves out smoothly under the guidance of the arc-shaped guide tube. The flexible member pushes the honing head to move from one end of the inner hole of the pipe to the other end.

[0023] When the driving motor is running, it drives the main bevel gear to mesh with the first bevel gear and the second bevel gear respectively. Since the first bevel gear is fixedly connected to the housing, the main bevel gear moves relative to the first bevel gear during rotation. When the main bevel gear rotates, it drives the rotating seat to rotate relative to the housing and the flexible member, so that the honing strip on the rotating seat rotates in the pipe fitting while moving axially in the pipe fitting, thereby honing the inner wall of the pipe fitting.

[0024] When the second bevel gear rotates, it drives the reciprocating screw to rotate relative to the rotating seat, and the sleeve drives the push seat to move back and forth in the rotating seat, so that the push seat pushes the wedge block on the outside of the honing bar back and forth, and cooperates with the elastic telescopic rod connected to the honing bar to make the honing bar reciprocate relative to the rotating seat when honing the inner hole of the pipe fitting, so as to facilitate the rapid discharge of waste chips generated during the honing of the inner hole of the pipe fitting;

[0025] S4: When the reciprocating screw rotates, it drives the large gear to rotate, and the small gear on the large gear shaft engages and transmits, and the small gear drives the active bevel gear and the auxiliary bevel gear to engage and transmit, so that the wire brush at the end of the rotating rod rotates, and the rotation direction of the wire brush is different from the rotation direction of the honing bar, and the inner wall of the pipe is honed from different directions.

[0026] Compared with the prior art, the present invention has the following beneficial effects:

[0027] The tubular parts inner hole honing device and the honing method thereof, by arranging a pushing assembly in a hydraulic pipe arranged parallel to the side of the pipe fitting, and using a flexible member to push the honing head, solves the problem that when honing the inner wall of a long pipe fitting, a long threaded rod needs to be arranged to drive the pipe fitting, resulting in a large occupied area of ​​the entire device, and effectively reduces the space occupied when honing the pipe fitting;

[0028] 2. The inner hole honing device for tubular parts and the honing method thereof drive the reciprocating screw to rotate relative to the rotating seat when the second bevel gear rotates, and the sleeve drives the push seat to move back and forth in the rotating seat, so that the push seat reciprocates the wedge block on the outer side of the honing bar, and cooperates with the elastic telescopic rod connected to the honing bar to make the honing bar reciprocate relative to the rotating seat when honing the inner hole of the pipe fitting, so that the honing bar will not always abut against the inner wall of the pipe fitting, which is convenient for the rapid discharge of waste chips generated when honing the inner hole of the pipe fitting, avoiding the debris from affecting the honing work of the inner wall of the pipe fitting, and ensuring the honing effect of the pipe fitting;

[0029] 3. The inner hole honing device and the honing method of tubular parts are provided with an adjustable abutment plate on the outer shell and the housing so that the abutment plate abuts against the inner wall of the pipe, so that the flexible part can push the honing head to improve the stability of the movement of the honing head in the pipe, ensure the honing process is stable and reliable, and is suitable for the inner hole processing of pipes of different sizes, with strong applicability;

[0030] 4. The inner hole honing device for tubular parts and the honing method thereof drive the large gear to rotate when the reciprocating screw rotates, and the small gear on the rotating shaft of the large gear engages and transmits, and the small gear drives the active bevel gear and the auxiliary bevel gear to engage and transmit, so that the wire brush at the end of the rotating rod rotates, and the rotation direction of the wire brush is different from the rotation direction of the honing bar, and the inner wall of the pipe is honed from different directions, so that the honing amount of the inner hole of the pipe is increased in unit time, the honing efficiency and honing quality of the inner hole of the pipe are improved, and the product qualification rate is improved.

DETAILED DESCRIPTION

[0048] A pushing assembly is arranged in the hydraulic pipe 4 , a honing head 6 is arranged at the end of the pushing assembly, and the honing head 6 is movably arranged in the pipe fitting 3 .

[0049] Furthermore, the pushing assembly includes a piston block 401 slidably arranged in the hydraulic pipe 4, an elastic element 402 (the elastic element 402 is set as a spring) is arranged between the piston block 401 and the inner wall of the hydraulic pipe 4, and a flexible member 403 is connected to the piston block 401, and one end of the flexible member 403 away from the piston block 401 passes through the hydraulic pipe 4 and is connected to the honing head 6.

[0051] Specifically, the pipe fitting 3 is clamped and positioned by the clamping part 2, and then the hydraulic pump 5 and the pushing assembly are controlled to work. The hydraulic pump 5 introduces the hydraulic oil into the hydraulic pipe 4 through the pipeline. The piston block 401 in the hydraulic pipe 4 is forced to move and drive the flexible member 403 to move to the outside of the hydraulic pipe 4. The flexible member 403 moves out smoothly under the guidance of the arc-shaped guide tube 404. The flexible member 403 pushes the honing head 6 from one end of the inner hole of the pipe fitting 3 to the other end, so that the honing head 6 moves axially along the pipe fitting 3. A pushing assembly is arranged in the hydraulic pipe 4 arranged parallel to the side of the pipe 3, and the flexible member 403 is used to push the honing head 6, which solves the problem that when the inner wall of a longer pipe 3 is honed, a longer driving rod needs to be arranged to drive the pipe 3 to move, resulting in a large area occupied by the entire device. The space occupied when honing the pipe 3 is effectively reduced, and the flexible member 403 swings during the pushing process of the honing head 6, friction processing is performed on the inner wall of the pipe 3 after honing, thereby improving the honing effect of the pipe 3.

[0053] Specifically, when the driving motor 7 is running, it drives the main bevel gear 701 to mesh with the first bevel gear 702 for transmission. When the first bevel gear 702 rotates, it drives the rotating seat 602 to rotate relative to the outer shell 601 and the flexible member 403, so that the honing strip 8 on the rotating seat 602 rotates in the pipe fitting 3 while moving axially in the pipe fitting 3, thereby honing the inner wall of the pipe fitting 3.

[0055] Specifically, when the driving motor 7 is running, it drives the main bevel gear 701 and the second bevel gear 1001 to engage and transmit. When the second bevel gear 1001 rotates, it drives the reciprocating screw 10 to rotate relative to the housing 601.

[0058] Example 5: Reference Figure 7 , Figure 8 , Fig. 9 , Fig.10 and Fig.11 , a tubular part inner hole honing device, based on Example 4, further, the bottom of the rotating seat 602 is connected to the shell 12 through a connecting block, the shell 12 is rotatably connected with a rotating rod 122, the two ends of the rotating rod 122 placed on the outside of the shell 12 are also connected with wire brushes 1222, the wire brush 1222 is movably against the inner wall of the pipe 3, the shell 12 is rotatably connected with a large gear 121 connected to the reciprocating screw rod 10, the shell 12 is connected with a small gear 123 meshing with the large gear 121 through a rotating shaft, the small gear 123 is provided with an active bevel gear 1231, and the rotating rod 122 is provided with a secondary bevel gear 1221 meshing with the active bevel gear 1231.

[0060] Example 6: Reference Figure 3 , Figure 4 and Figure 5A tubular part inner hole honing device, based on Example 5, further, the outer shell 601 and the shell 12 are both connected to a fixing plate 13, the fixing plate 13 is threadedly connected to a screw 131, one end of the screw 131 is movably connected to an abutment plate 132, and the abutment plate 132 is provided with a ball 1321 that movably abuts against the inner wall of the pipe 3.

[0061] Specifically, according to the size of the pipe 3, the screw 131 is rotated to adjust the distance between the abutment plate 132 and the fixed plate 13, so that the ball 1321 on the surface of the abutment plate 132 abuts against the inner wall of the pipe 3, so that the flexible member 403 can push the honing head 6 to improve the stability of the movement of the honing head 6 in the pipe 3, thereby ensuring that the honing process is stable and reliable, and is suitable for the inner hole processing of pipes 3 of different sizes, with strong applicability.

[0063] Specifically, when positioning the pipe fitting 3, the pipe fitting 3 is placed on the lower clamping seat 201, and the threaded rod 202 is rotated to make the connecting plate 2021 drive the upper clamping seat 203 to move downward, and the upper clamping seat 203 cooperates with the lower clamping seat 201 to clamp and position the pipe fitting 3.

[0064] The present invention also discloses a honing method of a tubular part inner hole honing device, comprising the following steps:

[0067] S3: Then control the hydraulic pump 5 and the drive motor 7 to operate;

[0068] The hydraulic pump 5 introduces the hydraulic oil into the hydraulic pipe 4 through the pipeline. The piston block 401 in the hydraulic pipe 4 is moved by force and drives the flexible member 403 to move to the outside of the hydraulic pipe 4.

A honing method for a tubular part inner hole honing machine according to claim 3, characterized in that: The following steps are involved: S1: placing the pipe fitting (3) on the lower clamping seat (201), and rotating the threaded rod (202) so that the connecting plate (2021) drives the upper clamping seat (203) to move downward, and the upper clamping seat (203) cooperates with the lower clamping seat (201) to clamp and position the pipe fitting (3); S2: Then, according to the size of the pipe (3), the screw rod (131) is rotated to adjust the distance between the abutting plate (132) and the fixing plate (13), so that the ball (1321) on the surface of the abutting plate (132) abuts against the inner wall of the pipe (3), and at the same time, the adjusting tube (112) is rotated to make the adjusting tube (112) move axially relative to the connecting tube (111), thereby adjusting the position of the conical block (113), so that when the conical block (113) abuts against the wedge block (801), the wedge block (801) drives the honing bar (8) to move to the maximum distance and abut against the inner wall of the pipe (3); S3: then controlling the hydraulic pump (5) and the drive motor (7) to operate; The hydraulic pump (5) introduces hydraulic oil into the hydraulic pipe (4) through a pipeline, and the piston block (401) in the hydraulic pipe (4) is moved by force and drives the flexible member (403) to move toward the outside of the hydraulic pipe (4). The flexible member (403) moves out smoothly under the guidance of the arc-shaped guide tube (404), and the flexible member (403) pushes the honing head (6) to move from one end of the inner hole of the pipe (3) to the other end; When the driving motor (7) is in operation, it drives the main bevel gear (701) to mesh with the first bevel gear (702) and the second bevel gear (1001) for transmission. Since the first bevel gear (702) is fixedly connected to the housing (601), the main bevel gear (701) moves relative to the first bevel gear (702) during rotation. When the main bevel gear (701) rotates, it drives the rotating seat (602) to rotate relative to the housing (601) and the flexible member (403). When the honing bar (8) on the rotating seat (602) moves axially in the pipe (3), it also rotates in the pipe (3), thereby honing the inner wall of the pipe (3). When the second bevel gear (1001) rotates, it drives the reciprocating screw rod (10) to rotate relative to the rotating seat (602), and the sleeve (1002) drives the push seat (11) to move back and forth in the rotating seat (602), so that the push seat (11) pushes the wedge block (801) on the outside of the honing bar (8) back and forth, and cooperates with the elastic telescopic rod (901) connected to the honing bar (8) to make the honing bar (8) reciprocate relative to the rotating seat (602) when honing the inner hole of the pipe fitting (3), so as to facilitate the rapid discharge of waste chips generated when honing the inner hole of the pipe fitting (3); S4: When the reciprocating screw (10) rotates, it drives the large gear (121) to rotate, and the small gear (123) on the rotating shaft of the large gear (121) engages in transmission. The small gear (123) drives the active bevel gear (1231) to engage in transmission with the auxiliary bevel gear (1221), so that the wire brush (1222) at the end of the rotating rod (122) rotates, so that the rotation direction of the wire brush (1222) is different from the rotation direction of the honing bar (8), and the inner wall of the pipe (3) is honed from different directions.
