Description

Technical Field

[0001] The present invention belongs to the field of processing of particulate filter tubes, and particularly relates to a limiting tooling for a particulate filter tube sleeved with a two-way rubber tube. Background Art

[0002] In order to prevent soot particles from escaping into the environment, vehicles with a fuel engine are equipped with a device for post-treating the exhaust gas of the fuel engine - an Otto particulate filter (OPF). The Otto particulate filter captures the soot particles in the exhaust gas of the fuel engine and prevents the soot particles from escaping into the environment. Therefore, the Otto particulate filter is loaded with soot particles over time and its load state increases. Once the Otto particulate filter reaches a high load state, it can no longer perform or cannot fully perform the function of filtering the exhaust gas. It is necessary to replace the Otto particulate filter in a timely manner so that the exhaust gas of the fuel engine remains within the pre-specified standard limits.

[0003] When the particulate filter tube of the particulate filter is produced, it is necessary to sleeve a rubber tube. At present, the rubber tube is mainly sleeved manually. The installation process is laborious, the installation efficiency is low, and the product production quality is poor. Summary of the Invention

[0004] The purpose of the present invention is to provide a limiting tooling for a particulate filter tube sleeved with a two-way rubber tube, which improves the sleeving efficiency of the rubber tube and the accuracy of the installation position, and improves the production quality and production efficiency of the product.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solution: a limiting tooling for a particulate filter tube sleeved with a two-way rubber tube, comprising: a substrate, a rubber tube installation mechanism, a fixed limiting member, a first movable limiting member and a second movable limiting member. The rubber tube installation mechanism is fixedly installed on the substrate. The fixed limiting member, the first movable limiting member and the second movable limiting member are arranged in sequence on the substrate along the length direction of the rubber tube installation mechanism. One end of the pipe fitting is positioned on the base of the fixed limiting member. The first movable limiting member and the second movable limiting member are abutted against the lower part of the pipe fitting. The first movable limiting member is slidably connected to the substrate through a first slide rail, and the first slide rail is perpendicular to the pipe fitting. The second movable limiting member is slidably connected to the substrate through a second slide rail, and the second slide rail is parallel to the first slide rail.

[0006] As a further description of the above technical solution:

[0007] The rubber tube installation mechanism includes a slideway, a sliding seat and a rubber tube clamping member. The slideway is fixedly installed on the substrate. The sliding seat is slidably connected to the slideway. The rubber tube clamping member is fixedly installed on the sliding seat. The rubber tube is placed in the rubber tube clamping member.

[0008] As a further description of the above technical solution:

[0009] The fixed limiting member further includes an elbow clamp and a buckle. The pipe fitting is placed on the base, one end of the pipe fitting abuts against the side plate of the base, the elbow clamp is fixedly installed on the base, and the clamping head of the elbow clamp presses the pipe fitting on the base. The buckle is fixedly installed on the base, and the pipe fitting is buckled in the buckle.

[0010] As a further description of the above technical solution:

[0011] An avoidance groove is further provided on the base, and the flange at the end of the pipe fitting is clamped in the avoidance groove.

[0012] As a further description of the above technical solution:

[0013] The first movable limiting member includes a mounting frame, a first support arm and two second support arms. The mounting frame is slidably connected to the first slide rail. The first support arm is hinged to the mounting frame. A first stop block is provided on the first support arm. The two second support arms are symmetrically arranged at both ends of the first support arm and fixed by fasteners. The first support arm and the second support arm form a "V"-shaped structure.

[0014] As a further description of the above technical solution:

[0015] The first stop block is threadedly connected to the first support arm.

[0016] As a further description of the above technical solution:

[0017] A second stop block is further provided at one end of the slideway, and the height of the second stop block is equal to the height of the first stop block.

[0018] As a further description of the above technical solution:

[0019] A plurality of positioning points are provided on the pipe fitting. The positioning points include two convex ribs arranged in parallel along the axial direction of the pipe fitting. The rubber hose is clamped in the positioning points, and the two convex ribs are symmetrically arranged at both ends of the rubber hose.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0021] 1. In the present invention, the pipe fitting on which the hose is to be installed is placed on a fixed limiter for positioning. The pipe fitting is positioned by a buckle and two elbow clamps. The first movable limiter and the second movable limiter are against the bottom of the pipe fitting (forming a support). The first movable limiter and the second movable limiter have the same structure. The hose is placed in the hose clamp of the hose installation mechanism. The hose clamp slides along the slideway on the base plate through the sliding seat to sleeve the clamped hose onto the pipe fitting. The position of the sliding seat is limited by the blocks on the first movable limiter and the second movable limiter and the block at one end of the slideway. When the sliding seat is pressed by the block and stops moving, the hose clamp sleeves the hose to the set position on the pipe fitting. Since multiple hoses need to be sleeved on the pipe fitting, after the hose clamp sleeves one hose, it returns to its position and replenishes the hose, and then repeats the above action. At the same time, since multiple hoses need to be installed on the pipe fittings, in order to avoid the front movable stopper affecting the installation of the rear hoses, the movable stopper can be avoided by sliding on the slide rail. In order to avoid interference with the pipe fittings during sliding, the fasteners can be loosened and the first support arm and the second support arm can be rotated and leveled. After the hose installation is completed, the elbow clamp is opened and the pipe fittings are taken out. The mechanical structure improves the efficiency of hose installation and the accuracy of the installation position, thereby improving product production quality and production efficiency.

[0022] 2. In the present invention, in order to further ensure the accuracy of the hose sleeve position, a number of positioning points are set on the pipe fitting, and the positioning points include two convex ribs arranged parallel to the axial direction of the pipe fitting. The hose is clamped in the positioning points, and the two convex ribs are symmetrically arranged at both ends of the hose. The two convex ribs limit the displacement of the hose in the pipe fitting.

[0032] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the scope of protection of the present invention.

[0033] Please refer to Figures 1-6 , the present invention provides a technical solution: a particle filter tube limiting tooling for a two-way rubber hose, including: a substrate 1, a rubber hose installation mechanism 2, a fixed limiting member 3, a first movable limiting member 4 and a second movable limiting member 5. The rubber hose installation mechanism 2 is fixedly installed on the substrate 1. The fixed limiting member 3, the first movable limiting member 4 and the second movable limiting member 5 are arranged in sequence on the substrate 1 along the length direction of the rubber hose installation mechanism 2. One end of the pipe fitting 6 is positioned on the base 31 of the fixed limiting member 3. The first movable limiting member 4 and the second movable limiting member 5 are abutted against the lower side of the pipe fitting 6. The first movable limiting member 4 is slidably connected to the substrate 1 through the first slide rail 41. The first slide rail 41 is perpendicular to the pipe fitting 6. The second movable limiting member 5 is slidably connected to the substrate 1 through a second slide rail. The second slide rail is parallel to the first slide rail 41.

[0034] The hose installation mechanism 2 includes a slideway 21, a sliding seat 22 and a hose clamping member 23. The slideway 21 is fixedly installed on the base plate 1. The sliding seat 22 is slidably connected to the slideway 21. The hose clamping member 23 is fixedly installed on the sliding seat 22. The hose 7 is placed inside the hose clamping member 23.

[0035] The fixed limiting member 3 further includes an elbow clamp 32 and a buckle 33. The pipe fitting 6 is placed on the base 31. One end of the pipe fitting 6 abuts against the side plate 311 of the base 31. The elbow clamp 32 is fixedly installed on the base 31, and the clamping head 321 of the elbow clamp 32 presses the pipe fitting 6 onto the base 31. The buckle 33 is fixedly installed on the base 31, and the pipe fitting 6 is buckled inside the buckle 33 to fully position the pipe fitting 6.

[0036] An avoidance groove 312 is further provided on the base 31. The flange at the end of the pipe fitting 6 is clamped inside the avoidance groove 312 to ensure the positioning quality of the pipe fitting 6 and ensure the smooth sleeving of the hose.

[0037] The first movable limiting member 4 includes a mounting frame 42, a first support arm 43 and two second support arms 44. The mounting frame 42 is slidably connected to the first slide rail 41. The first support arm 43 is hinged to the mounting frame 42. A first stop block 431 is provided on the first support arm 43. The two second support arms 44 are symmetrically arranged at both ends of the first support arm 43 and are fixed by a fastener 45. The first support arm 43 and the second support arms 44 form a "V" - shaped structure. The first support arm 43 and the second support arms 44 can rotate to adjust the included angle to ensure the supporting effect on the pipe fitting and the flexible detachment from the pipe fitting.

[0038] The first stop block 431 is connected to the first support arm 43 by threads, and the position of the first stop block can be flexibly adjusted, thereby adjusting the position where the sliding seat 22 stops, and further controlling the installation position of the hose.

[0039] A second stop block 8 is further provided at one end of the slideway 21. The height of the second stop block 8 is equal to the height of the first stop block 431 to accurately control the position where the sliding seat 22 stops and precisely control the installation of the hose.

[0040] A number of positioning points 61 are provided on the pipe fitting 6. The positioning points 61 include two ribs arranged in parallel along the axial direction of the pipe fitting 6. The hose 7 is clamped inside the positioning points 61. The two ribs are symmetrically arranged at both ends of the hose 7, and the two ribs limit the displacement of the hose on the pipe fitting.

[0041] Working principle: Place the pipe fitting to be installed with the hose on the fixed limiter for positioning. The pipe fitting is positioned by the buckle and two elbow clamps. The first movable limiter and the second movable limiter are against the bottom of the pipe fitting (forming a support). The first movable limiter and the second movable limiter have the same structure. Place the hose in the hose clamp of the hose installation mechanism. The hose clamp slides along the slideway on the base plate through the sliding seat to sleeve the clamped hose onto the pipe fitting. The position of the sliding seat is limited by the blocks on the first movable limiter and the second movable limiter and the block at one end of the slideway. When the sliding seat is pressed by the block and stops moving, the hose clamp sleeves the hose to the set position on the pipe fitting. Since multiple hoses need to be sleeved on the pipe fitting, after the hose clamp sleeves one hose, it returns to its position and replenishes the hose, and then repeats the above action. At the same time, since multiple hoses need to be installed on the pipe fitting, in order to avoid the movable limiter in the front from affecting the installation of the hose at the back, the movable limiter can be avoided by sliding on the slide rail. In order to avoid interference with the pipe fitting during sliding, the fastener can be loosened and the first support arm and the second support arm can be rotated to level. After the hose is installed, open the elbow clamp and take out the pipe fitting. The mechanical structure improves the efficiency of hose installation and the accuracy of the installation position, and improves product production quality and production efficiency. In order to further ensure the accuracy of the hose installation position, a number of positioning points are provided on the pipe fitting. The positioning points include two convex ribs arranged parallel to the axial direction of the pipe fitting. The hose is clamped in the positioning points. The two convex ribs are symmetrically arranged at both ends of the hose. The two convex ribs limit the displacement of the hose in the pipe fitting.

Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
