[0003] Currently, to solve the problem of root cleaning and back chipping of angle iron, the following methods are generally adopted in the industry: one is to complete the root cleaning and back chipping work through manual operation, and the operator uses a grinding wheel or a chisel to clean the angle iron; the second is to use a simple fixed fixture in cooperation with manual tools for semi-automatic operation; the third is to adopt special root cleaning and back chipping equipment, which usually includes a clamping device and a processing tool and can realize the basic clamping and cleaning functions of the angle iron. However, although these methods can meet the processing requirements to a certain extent, there are still many deficiencies.

[0004] Among the above methods, manual operation has a large labor intensity, low efficiency, and it is difficult to ensure processing accuracy; although the method of using a fixed fixture in cooperation with manual tools has been slightly improved, there are still defects in the limit and stability in the length direction of the angle iron; and the existing special equipment often has a complex structure, is difficult to adapt to the processing requirements of angle irons of different sizes, and at the same time, due to the lack of a limiting structure along the length direction of the angle iron, the angle iron may move along the length direction, and the reliability of processing is not good. Therefore, there is an urgent need for a device that can stably complete the root cleaning and back chipping work of angle iron to solve the problem of unstable clamping in the prior art.

[0010] By adopting the above technical scheme, the clamping driving member can drive the clamping lead screw to rotate, and the clamping lead screw drives the two clamping sliders to move towards or away from each other, so as to realize the clamping or release of the angle iron by the two clamping members. This scheme has a high degree of automation in the clamping process, is convenient to operate, improves the work efficiency, and can adapt to angle irons of different sizes, with good versatility.

[0011] Optionally, the clamping member is provided with a clamping groove, the clamping groove is used for clamping the end of the angle iron along the width direction, and the limiting component is matched with the clamping groove.

[0012] By adopting the above technical solution, the clamping member is provided with a clamping groove capable of accurately clamping the end of the angle iron in the width direction, ensuring the stability of the angle iron during the clamping process and avoiding vertical displacement during processing. The limiting component cooperates with the clamping groove, further enhancing the limiting effect on both ends of the angle iron in the length direction within the horizontal plane, effectively preventing the angle iron from loosening or shaking during the root clearing and back chipping process, thereby improving the processing accuracy and efficiency.

[0013] Optionally, there are two groups of the limiting components, the limiting components are arranged corresponding to the clamping member, the limiting component includes a limiting driving member, a limiting lead screw, and two limiting sliders.

[0014] By adopting the above technical solution, the clamping member is provided with a clamping groove for fixing the end of the angle iron, and the limiting component cooperates with the clamping groove to further enhance the fixing effect. In the limiting component, the limiting driving member drives the limiting lead screw to rotate, and the limiting lead screw drives the two limiting sliders to move towards or away from each other in the clamping groove, realizing precise limiting on both ends of the angle iron in the length direction, ensuring the stability of the angle iron during the root clearing and back chipping process, avoiding position deviation caused by vibration or external force, thereby improving the processing accuracy and efficiency, and being applicable to angle irons of different lengths.

[0015] Optionally, the root clearing and back chipping mechanism includes a root clearing component, the root clearing component includes a root clearing driving member, a gear, a first rack, and a root clearing knife.

[0016] By adopting the above technical solution, the root clearing and back chipping mechanism can realize the root clearing operation on the angle iron. Specifically, the root clearing driving member drives the first rack to slide along the support mechanism through the meshing transmission between the gear and the first rack, thereby driving the root clearing knife to move horizontally, so that the lower end of the root clearing knife precisely acts on the root of the angle iron for root clearing treatment. This solution ensures the automation and high efficiency of the root clearing operation, and at the same time improves the accuracy and consistency of root clearing.

[0018] By adopting the above technical solution, the cooperation of the first support member, the first elastic member, and the first pushing member can effectively clean the root of the angle iron. Specifically, the root cleaning knife can push the first pushing member to move towards the first support member, thereby pre-cleaning the impurities on the angle iron before root cleaning and reducing the risk of damage to the angle iron caused by impurities during root cleaning; the setting of the first elastic member enables the first pushing member to automatically move backward and reset after being not pushed by the root cleaning knife, thereby performing secondary cleaning on the upper surface of the angle iron after root cleaning, reducing impurity residue, and improving the root cleaning quality; the sliding connection mode of the first pushing member and the support mechanism ensures the stability of its movement, thereby improving the cleaning efficiency and accuracy.

The meshing transmission between the second rack and the gear enables the chamfering knife to reciprocate stably on the support mechanism, thereby efficiently completing the root chamfering task of the bottom of the angle iron. In addition, the position design of the chamfering knife ensures that it can accurately act on the part to be processed of the angle iron, improving the processing accuracy and efficiency; since the first rack and the second rack are both meshed with the same gear, the root cleaning and root chamfering of the angle iron can be simultaneously achieved through the rotation of the gear, improving the processing efficiency.

After the back-shoveling blade releases the pushing action on the second pusher, the second elastic member enables the second pusher to automatically reset, so that the back-shoveling blade can realize the pushing action on the second pusher again; the sliding connection mode between the second pusher and the support mechanism ensures the smoothness of its movement, further improving the reliability of cleaning the bottom of the angle iron.

[0023] Optionally, the lower end of the first pusher has the same shape as the lower end of the root cleaning knife, and the upper end of the second pusher has the same shape as the upper end of the back-shoveling knife.

[0025] Optionally, a first protrusion is provided on one side of the first pusher close to the root cleaning knife, and a second protrusion is provided on one side of the second pusher close to the back-shoveling knife.

[0026] By adopting the above technical solution, the first protrusion and the second protrusion are arranged so that there is a gap between the lower end of the root cleaning knife and the first pusher, and there is a gap between the lower end of the back-shoveling knife and the second pusher, thereby reserving space for the discharge of impurities, avoiding jamming caused by impurity accumulation and damage to the angle iron, and improving stability and processing quality.

[0037] As Figure 1 , Figure 2 and Figure 3 shown, an undercutting and back chipping machine for angle iron of steel structure parts (hereinafter simply referred to as "undercutting and back chipping machine") is disclosed in an embodiment of this application. The undercutting and back chipping machine includes a support mechanism 1, a clamping mechanism 2, and an undercutting and back chipping mechanism 3, which are used to realize reliable clamping of the angle iron 100 of the steel structure part and simultaneously realize undercutting and back chipping of the angle iron 100 of the steel structure part.

[0038] As Figure 1 , Figure 3 and Figure 4 shown, the clamping mechanism 2 is arranged on the support mechanism 1. The clamping mechanism 2 includes a clamping drive assembly 21, a clamping assembly 22, and a limiting assembly 23.

The clamping assembly 22 is used to clamp the angle iron 100. The limiting assembly 23 is arranged on the clamping assembly 22. The clamping assembly 22 is used to limit the two ends of the angle iron 100 along the length direction.

[0039] The undercutting and back chipping mechanism 3 is arranged on the support mechanism 1. The undercutting and back chipping mechanism 3 is used to perform undercutting and back chipping on the angle iron 100. On the basis that the angle iron 100 is stably clamped, the undercutting and back chipping mechanism 3 can reliably complete the undercutting and back chipping work of the angle iron 100, improve the processing accuracy and efficiency, and reduce the complexity and labor intensity of manual operation.

[0040] As Figure 1 , Figure 3 and Figure 4As shown, optionally, the clamping drive assembly 21 includes a clamping driver 211, a clamping lead screw 212, and two clamping sliders 213. The clamping assembly 22 includes two clamping members. The clamping driver 211 is connected to the support mechanism 1. One end of the clamping lead screw 212 is drivingly connected to the clamping driver 211, and the other end of the clamping lead screw 212 is rotatably connected to the support mechanism 1. The two clamping sliders 213 are screwed onto the clamping lead screw 212, and the two clamping sliders 213 are slidably connected to the support mechanism 1. The clamping members are correspondingly arranged with the clamping sliders 213, and the clamping members are correspondingly connected to the clamping sliders 213. The clamping lead screw 212 drives the two clamping sliders 213 to move towards or away from each other, so that the two clamping members clamp or release the angle iron 100.

[0041] The clamping driver 211 can drive the clamping lead screw 212 to rotate, and the clamping lead screw 212 drives the two clamping sliders 213 to move towards or away from each other, thereby realizing the clamping or release of the angle iron 100 by the two clamping members. Moreover, the clamping mechanism 2 can adapt to angle irons 100 of different sizes and has good versatility. The clamping driver 211 can be a motor, and the clamping lead screw 212 can be a bidirectional lead screw, that is, a lead screw with opposite thread pitches at both ends.

[0042] As Figure 1 、 Figure 3 and Figure 4 shown, optionally, the clamping member is provided with a clamping groove 221 for clamping the end of the angle iron 100 in the width direction. The clamping member is provided with the clamping groove 221, which can accurately clamp the end of the angle iron 100 in the width direction, ensure the stability of the angle iron 100 during the clamping process, and avoid vertical displacement during processing. The limiting assembly 23 cooperates with the clamping groove 221, further enhancing the limiting effect on both ends of the angle iron 100 in the length direction in the horizontal plane, effectively preventing the angle iron 100 from loosening or shaking during the root clearing and back chipping process, thereby improving the processing accuracy and efficiency.

[0043] As Figure 1 、 Figure 3 and Figure 4 shown, optionally, there are two groups of limiting assemblies 23, and the limiting assemblies 23 are correspondingly arranged with the clamping members. The limiting assembly 23 includes a limiting driver 231, a limiting lead screw 232, and two limiting sliders 233. The limiting driver 231 is arranged on the clamping member. One end of the limiting lead screw 232 is drivingly connected to the output end of the limiting driver 231, and the other end of the limiting lead screw 232 is rotatably connected to the clamping member. The two limiting sliders 233 are both screwed onto the limiting lead screw 232. The limiting sliders 233 are slidably matched with the clamping groove 221, and the limiting lead screw 232 can drive the two limiting sliders 233 to move towards or away from each other. The clamping member is provided with a sliding groove, and the limiting sliders 233 are slidably matched with the sliding groove.

[0044] The limit driving member 231 drives the limit lead screw 232 to rotate, and the limit lead screw 232 drives the two limit sliders 233 to move towards or away from each other in the clamping groove 221, achieving precise limit on both ends of the angle iron 100 in the length direction, ensuring the stability of the angle iron 100 during the root cleaning and back chipping process, avoiding position deviation caused by root cleaning and back chipping operations, vibration or external forces, etc., thereby improving the processing accuracy and efficiency, and being applicable to angle irons 100 of different lengths. The limit driving member 231 can be a motor, and the limit lead screw 232 can be a bidirectional lead screw.

[0045] As Figure 1 , Figure 3 and Figure 4 shown, optionally, the root cleaning and back chipping mechanism 3 includes a root cleaning assembly, and the root cleaning assembly includes a root cleaning driving member 311, a gear 312, a first rack 313 and a root cleaning tool 314. The root cleaning driving member 311 is arranged on the support mechanism 1, the output end of the root cleaning driving member 311 is drivingly connected to the gear 312, the first rack 313 is slidably connected to the support mechanism 1, the first rack 313 meshes with the gear 312, the end of the first rack 313 is connected to the root cleaning tool 314, so that the root cleaning tool 314 is arranged above the angle iron 100, the upper end of the root cleaning tool 314 is slidably connected to the support mechanism 1, and the lower end of the root cleaning tool 314 is used for root cleaning of the angle iron 100.

[0046] Through the meshing transmission between the gear 312 and the first rack 313, when the root cleaning driving member 311 drives the gear 312 to rotate, it can drive the first rack 313 to slide along the support mechanism 1, thereby driving the root cleaning tool 314 to move horizontally, so that the lower end of the root cleaning tool 314 precisely acts on the root of the angle iron 100 for root cleaning. This solution ensures the automation and high efficiency of the root cleaning operation, and at the same time improves the accuracy and consistency of root cleaning. The root cleaning driving member 311 can be a motor, which is mounted on the support mechanism 1.

[0047] As Figure 1 , Figure 3 and Figure 4 shown, optionally, the root cleaning assembly includes a first support member 315, a first elastic member 316 and a first pushing member 317, and the cooperation of the first support member 315, the first elastic member 316 and the first pushing member 317 can effectively clean the root of the angle iron 100. The first support member 315 is connected to the support mechanism 1, one end of the first elastic member 316 is connected to the first support member 315, and the other end of the first elastic member 316 is connected to the first pushing member 317. The upper end of the first pushing member 317 is slidably connected to the support mechanism 1, the first pushing member 317 is arranged above the angle iron 100, and the lower end of the first pushing member 317 is used for cleaning the root of the angle iron 100.

[0048] The root cleaning tool 314 pushes the first pushing member 317 to move towards the first support member 315, thereby pre-cleaning the impurities on the angle iron 100 before root cleaning and reducing the risk of damage to the angle iron 100 caused by impurities during root cleaning. The setting of the first elastic member 316 enables the first pushing member 317 to automatically move back in the direction away from the first support member 315 after being pushed by the root cleaning tool 314, thereby performing secondary cleaning on the upper surface of the angle iron 100 after root cleaning, reducing impurity residue, and improving the root cleaning quality. The sliding connection mode of the first pushing member 317 with the support mechanism 1 ensures the stability of its movement, thereby improving the cleaning efficiency and accuracy.

[0049] As Figure 1 , Figure 3 and Figure 4 shown, optionally, the root cleaning and back chipping mechanism 3 includes a back chipping assembly, and the back chipping assembly includes a second rack 321 and a back chipping tool 322. The second rack 321 is slidably connected to the support mechanism 1, and the end of the second rack 321 is connected to the back chipping tool 322. The second rack 321 meshes with the gear 312, so that when the gear 312 rotates, the moving directions of the first rack 313 and the second rack 321 are opposite. Both the second rack 321 and the back chipping tool 322 are located below the angle iron 100, and the back chipping tool 322 is used for back chipping the angle iron 100.

[0050] The meshing transmission of the second rack 321 with the gear 312 enables the back chipping tool 322 to reciprocate stably on the support mechanism 1, thereby efficiently completing the back chipping task at the bottom of the angle iron 100. In addition, the position design of the back chipping tool 322 ensures that it can accurately act on the part to be processed of the angle iron 100, improving the processing accuracy and efficiency. Since both the first rack 313 and the second rack 321 are meshed with the same gear 312, the root cleaning and back chipping of the angle iron 100 can be achieved simultaneously by the rotation of the gear 312, improving the processing efficiency.

[0051] As Figure 1 , Figure 2 and Figure 4 shown, the support mechanism 1 is provided with a chute for supporting the second rack 321 and a through hole for avoiding the first rack 313, so that the first rack 313 and the second rack 321 can move smoothly. This root cleaning and back chipping machine includes necessary avoiding structures. For example, the first pushing member 317 is provided with a through hole, so that the first rack 313 slides through the through hole to avoid interference between the first rack 313 and the first pushing member 317.

[0052] As Figure 1 , Figure 3 and Figure 4As shown, optionally, the root clearing component and the back chipping component have similar implementation principles. The back chipping component includes a second support member 323, a second elastic member 324, and a second pushing member 325. The second support member 323 is connected to the support mechanism 1. One end of the second elastic member 324 is connected to the second support member 323, and the other end of the second elastic member 324 is connected to the second pushing member 325. The lower end of the second pushing member 325 is slidably connected to the support mechanism 1. The second pushing member 325 is disposed below the angle iron 100, and the upper end of the second pushing member 325 is used to clean the bottom of the angle iron 100. The second pushing member 325 can be horizontally moved under the action of the second elastic member 324, so as to clean the angle iron 100 before and after the back chipping of the angle iron 100 by the back chipping tool 314, reduce the damage of impurities to the angle iron 100 during the back chipping process, and reduce the residue of impurities at the bottom of the angle iron 100, improving the back chipping processing quality. The second support member 323 provides a stable installation base for the second elastic member 324, ensuring the reliability of the entire back chipping component structure. The second elastic member 324 enables the second pushing member 325 to automatically reset after the back chipping tool 322 releases the pushing action on the second pushing member 325, so that the back chipping tool 322 can realize the pushing action on the second pushing member 325 again. The sliding connection mode of the second pushing member 325 and the support mechanism 1 ensures the smoothness of its movement, further improving the reliability of cleaning the bottom of the angle iron 100. Both the first elastic member 316 and the second elastic member 325 can be springs, and the type and specific size of the springs can be selected according to needs.

[0053] As Figure 1 , Figure 3 and Figure 4 shown, optionally, a first protrusion is provided on the side of the first pushing member 317 close to the root clearing tool 314, and a second protrusion is provided on the side of the second pushing member 325 close to the back chipping tool 322. The settings of the first protrusion and the second protrusion can make a gap between the lower end of the root clearing tool 314 and the first pushing member 317, and a gap between the lower end of the back chipping tool 322 and the second pushing member 325, so as to reserve space for the discharge of impurities, avoid the accumulation of impurities causing jamming and damage to the angle iron 100, and improve the stability and processing quality. The initial positions and the end positions of the first pushing member 317, the root clearing tool 314, the second pushing member 325, and the back chipping tool 322 can be set according to needs; at the same time, the positions of the first support member 315 and the second support member 323 are also set according to actual needs.

[0054] As Figure 4 , Figure 5 and Figure 6 shown, optionally, the lower end of the first pushing member 317 has the same shape as the lower end of the root clearing tool 314, and the upper end of the second pushing member 325 has the same shape as the upper end of the back chipping tool 322, which can avoid damaging the angle iron 100 during the cleaning process while effectively cleaning, ensuring the processing quality.

[0055] As Figure 1 、 Figure 3 and Figure 4 shown, the support mechanism 1 includes a support table 11 and an upper support member 12. The support table 11 plays an overall support role. The upper support member 12 is erected above the support table 11. The upper support member 12 is used for sliding connection with the root clearing knife 314 and the first pushing member 317, and the upper support member 12 is fixedly connected to the first support member 315. The shape of the upper support member 12 is not limited, and it can be plate-shaped or rod-shaped, and the volume of the upper support member 12 is relatively small, so that the angle iron 100 can be put in or taken out through the gap between the upper support member 12 and the clamping member. The putting in and taking out of the angle iron 100 can be realized by using a clamping jaw or other structures that can achieve clamping. The upper support member 12 is erected on the support table 11 through an upper support bracket 13. The root clearing assembly may further include a first guiding rod (not shown in the figure). One end of the first guiding rod is connected to the first support member 315, and the other end of the first guiding rod is connected to the upper support bracket 13. The first guiding rod slidably penetrates through the first pushing member 317 and the root clearing knife 314, so that the first elastic member 316 is sleeved on the outer periphery of the first guiding rod, thereby providing a guiding effect for the first elastic member 316 through the first guiding rod.

[0056] As Figure 1 、 Figure 3 and Figure 4 shown, similarly, the support mechanism 1 includes a lower support member 14. The lower support member 14 is connected to the support table 11. The second support member 323 is fixedly connected to the lower support member 14. Both the second pushing member 325 and the back chipping knife 322 are slidably connected to the lower support member 14. Similarly, the back chipping assembly may include a second guiding rod (not shown in the figure). One end of the second guiding rod is connected to the second support member 323, and the other end of the second guiding member is connected to the lower support member 14. The second guiding rod slidably penetrates through the second pushing member 325 and the back chipping knife 322, so that the second elastic member 324 is sleeved on the outer periphery of the second guiding member, thereby playing a guiding role for the second elastic member 324. In other embodiments, other forms of guiding structures may also be selected to improve the guiding performance of the first elastic member 316 and the second elastic member 324, or the guiding structure may not be provided.

[0057] It can be understood that the root clearing and back chipping machine further includes necessary structures for functions such as connection, support, drive, positioning, limiting, and control, so that the root clearing and back chipping machine can operate normally; parameters such as the shape, size, material, and set quantity of each part of the root clearing and back chipping machine can be determined according to needs as long as the corresponding functions can be achieved.

[0058] The implementation principle of the root cleaning and back chipping machine for angle iron of steel structure parts in the embodiments of the present application is as follows: The clamping and driving assembly 21 drives the clamping assembly 22 to firmly clamp the angle iron 100, and the limiting assembly 23 restricts the movement of the angle iron 100 along the length direction. The root cleaning and back chipping mechanism 3 can simultaneously complete the root cleaning and back chipping operations on the angle iron 100 when the angle iron 100 is limited in both the vertical and horizontal directions, ensuring high efficiency and reliable quality in the processing process. Through reasonable structural design and coordinated work among components, the entire device realizes precise limiting and efficient processing of the angle iron 100.

[0059] The above are all preferred embodiments of the present application. The protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application shall be covered within the protection scope of the present application.
