Description

Technical Field

[0001] This utility model relates to the field of hollow rod materials, and in particular to a hollow rod material feeding and guiding component. Background Technology

[0002] In the field of machining, such as the canes used in medical assistive devices, hollow rods are assembled by welding. One of the main raw materials is the hollow rod, which is typically tens of meters long, requiring precise cutting. Traditional feeding methods often use clamping conveyors, pushing the rod forward with a clamping device. However, this method has significant drawbacks: when the rod is conveyed forward, its end is suspended in the air, and due to gravity, the end tends to sag. This not only prevents the rod from remaining horizontal during cutting, affecting cutting accuracy, but can also cause uneven stress on the cutting tool, reducing tool life and increasing production costs. More importantly, the cut products often fail to meet dimensional accuracy requirements, leading to a lower product yield. Utility Model Content

[0003] To address the shortcomings of existing technologies, this utility model provides a hollow rod material feeding and guiding assembly. This assembly can accurately guide hollow rod materials, preventing them from sagging due to gravity and ensuring cutting accuracy.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a hollow rod material feeding and guiding assembly, comprising:

[0005] A mounting backplate, wherein a through hole is provided in the middle of the mounting backplate;

[0006] A mounting plate is fixed to a mounting back plate. Several guide wheel components are fixed on the mounting plate in a uniform ring shape. The through hole is located in the central area of ​​the guide wheel components. Rotatable guide wheels are connected to the guide wheel components. The guide wheels are made of flexible material. A cleaning component is also fixed on each guide wheel component. The cleaning component is in contact with the guide wheel.

[0007] An adjustment mechanism is provided, which is connected to a guide wheel component, which is connected to a guide groove.

[0008] Furthermore, the number of guide wheel components is four, wherein the first guide wheel component and the second guide wheel component are distributed horizontally and located in the upper region, and the third guide wheel component and the fourth guide wheel component are distributed vertically and located in the lower region.

[0009] Furthermore, the guide wheel component adopts a guide block, and the front end of the guide block is provided with a fork, and the guide wheel is rotatably connected in the fork.

[0010] Furthermore, a mounting base is fixed on the guide block, and the cleaning component is a brush roller installed in the mounting base, with the brush roller in contact with the guide wheel.

[0011] Furthermore, the guide block is slidably connected in the guide groove of a limiting seat.

[0012] Furthermore, the adjustment mechanism includes a first ball screw mechanism and a second ball screw mechanism, each driven by a motor. The first and second ball screw mechanisms have two helical sections with opposite helical directions on their screws. A first adjusting block and a second adjusting block are respectively connected to the two helical sections of the first ball screw mechanism. The first and second adjusting blocks are fixedly connected to the first guide wheel component and the second guide wheel component, respectively. A third adjusting block and a fourth adjusting block are connected to the two helical sections of the screw of the second ball screw mechanism. The third and fourth adjusting blocks are fixedly connected to the third guide wheel component and the fourth guide wheel component, respectively.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. This hollow rod material feeding and guiding assembly can accurately guide the hollow rod material, preventing it from sagging due to gravity and ensuring cutting accuracy. At the same time, the flexible guide wheel can prevent the outer surface of the hollow rod material from being scratched.

Hollow rod material; Detailed Implementation

[0021] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0022] like Figures 1 to 3 The hollow rod feeding and guiding assembly shown includes:

[0023] A mounting backplate 1, wherein a through hole 2 is provided in the middle of the mounting backplate 1;

[0024] A mounting plate 3 is fixed on a mounting back plate 1. Several guide wheel components are fixed on the mounting plate 3 in a uniform ring shape. The through hole 2 is located in the central area of ​​several guide wheel components. A rotatable guide wheel 4 is connected to the guide wheel component. The guide wheel 4 is made of flexible material. A cleaning component is also fixed on each guide wheel component. The cleaning component is in contact with the guide wheel 4.

[0025] An adjustment mechanism is provided, which is connected to a guide wheel component, which is connected to a guide groove 5.

[0026] The process of using this utility model is as follows: First, the mounting back plate 1 is installed on the frame. The frame can be a portal frame or other brackets that facilitate the installation of the mounting back plate 1. Since the mounting back plate 1 has a through hole 2, which is usually set to be large enough to accommodate hollow rods 23 of different diameters, the guide wheel components can be directly installed on the mounting plate 3 through the mounting plate 3. Then, the mounting plate 3 is fixed on the mounting back plate 1. The position of the guide wheel components is adjusted according to the outer diameter of the hollow rod 23 through the adjustment mechanism so that the spacing between the guide wheels 4 matches the hollow rod 23. During feeding, the robot at the rear end grabs the hollow rod 23 and feeds it into the through hole 2. The outer edge of the hollow rod 23 contacts the guide wheel 4, thereby completing the guidance of the hollow rod 23. After reaching the appropriate position, the robot stops moving forward, and the cutting component at the front end of the guiding component begins to cut. In this way, the front end of the hollow rod 23 is prevented from sagging due to gravity, which would affect the cutting accuracy. Furthermore, since the guide wheel 4 is rotatable and made of flexible material, it experiences rolling friction with the hollow rod 23, preventing damage to the outer edge of the hollow rod 23. During the guiding process, if there are iron filings or impurities on the hollow rod 23, they will adhere to the guide wheel 4. At this time, the cleaning component can scrape off the iron filings on the guide wheel 4, preventing the accumulation of iron filings that could obstruct the guiding process.

[0027] Furthermore, there are four guide wheel components. First guide wheel components 6 and 7 are horizontally distributed in the upper region, while third guide wheel components 8 and 9 are vertically distributed in the lower region. This distribution of four guide wheel components ensures that the hollow rod 23 receives omnidirectional support, especially during cutting, where horizontal and vertical forces are balanced, ensuring cutting accuracy. Simultaneously, the staggered distribution of first guide wheel components 6 and 7 in the upper region and third and fourth guide wheel components 8 and 9 in the lower region prevents interference between the guide wheel components due to excessive proximity.

[0028] Furthermore, the guide wheel component adopts a guide block 10, and the front end of the guide block 10 is provided with a fork head 11, in which the guide wheel 4 is rotatably connected. Because the guide block 10 is used as the guide wheel component, and its front end is provided with a fork head 11, with the guide wheel 4 rotatably connected within the fork head 11, this structure makes the installation of the guide wheel 4 more stable and reliable. Even during long-term high-speed operation and frequent use, it is less prone to loosening or falling off, ensuring the continuity and stability of the guiding process.

[0029] Furthermore, a mounting base 12 is fixed on the guide block 10, and the cleaning component is a brush roller 13 installed in the mounting base 12, which contacts the guide wheel 4. Specifically, the cleaning component of this utility model is designed as a brush roller 13 installed on the guide block 10, and the brush roller 13 contacts the guide wheel 4. Due to the good elasticity and cleaning ability of the brush roller 13, it can more effectively clean the surface of the guide wheel 4. At the same time, during the rotation of the guide wheel 4, the brush roller 13 can continuously clean away the tiny impurities and dust adhering to the guide wheel 4, ensuring that the surface of the guide wheel 4 is always clean, further improving the accuracy and reliability of the guide, and reducing problems such as rod material conveying deviation that may be caused by impurities.

[0030] Furthermore, the guide block 10 is slidably connected in the guide groove of a limiting seat 14. Specifically, by slidably connecting the guide block 10 in the limiting seat 14, the guide block 10 can move only in the horizontal or vertical direction, ensuring that the guide wheel 4 on it will not deviate, thereby ensuring that the hollow rod 23 can maintain horizontal movement when guiding the hollow rod 23.

[0031] Furthermore, the adjustment mechanism includes a first ball screw mechanism 16 and a second ball screw mechanism 17, both driven by a motor 15. The first ball screw mechanism 16 and the second ball screw mechanism 17 have two helical sections 18 with opposite helical directions on their screws. A first adjusting block 19 and a second adjusting block 20 are respectively connected to the two helical sections 18 of the first ball screw mechanism 16. The first adjusting block 19 and the second adjusting block 20 are fixedly connected to the first guide wheel component 6 and the first guide wheel component 7, respectively. A third adjusting block 21 and a fourth adjusting block 22 are connected to the two helical sections 18 of the screw of the second ball screw mechanism 17. The third adjusting block 21 and the fourth adjusting block 22 are fixedly connected to the third guide wheel component 8 and the fourth guide wheel component 9, respectively. Specifically, in order to enable the first guide wheel component 6 and the first guide wheel component 7 to move synchronously and ensure the coordination and consistency of the movement of the guide wheel components during the adjustment process, when adjusting the spacing of the guide wheels 4, it is only necessary to start the motor 15 on them. This will prevent the two guide wheels 4 from contacting the hollow rod material 23 at the same time. Similarly, the third guide wheel component 8 and the fourth guide wheel component 9 have the same movement effect.

[0032] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
