[0002] Automobiles are the most important means of transportation for people to travel now and have entered tens of millions of families. Due to the large number of internal parts of automobiles, the automobile processing industry is also growing stronger; various pipelines are required for automobile parts, and the pipelines need to be cut into different lengths during the processing process so as to be applied to different products.

[0003] After the round tube is cut, burrs adhering to the inner wall of the round tube will appear on the cut surface. These burrs will affect the subsequent processing and use of the round tube. Therefore, the burrs need to be removed first after cutting. The existing burr removal process uses a steel brush to brush the cut surface of the round tube, and the burrs at the cut of the round tube are removed by friction. However, this method can only cut the flat cut surface, and has great limitations in use. When facing a special-shaped cut surface, it is impossible to remove the burrs on the sunken cut surface, and it cannot meet the processing requirements of different products. Therefore, it is necessary to study a new technical solution to solve the above problems. Summary of the Utility Model

[0004] In view of this, aiming at the deficiencies existing in the prior art, the main purpose of the utility model is to provide a burr removing device for round tubes, which can effectively solve the problems that the existing burr removal method can only be carried out on the flat cut surface, has great limitations in use and cannot meet the processing requirements of different products.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A burr removing device for round tubes includes a base, a support frame, a processing head, a first driving mechanism and a fixing component; the support frame is arranged on the base, and there are two support frames arranged symmetrically horizontally. Each support frame is provided with an adaptation groove for cooperating with an external round tube; the processing head is arranged on the base so as to be able to move back and forth horizontally and is located outside the support frame. The processing head corresponds to the adaptation groove axially and cooperates with the external round tube. There is a through hole with an outer end opening in the processing head. The outer end surface of the processing head is integrally concave inwardly with grooves. The grooves are multiple and arranged at equal angles. The multiple grooves divide the side wall of the processing head into multiple elastic parts. The outer end side wall of each elastic part is integrally convex outwardly with a convex part for cooperating with the inner side wall of the round tube; the first driving mechanism is arranged on the base and drives the processing head to move back and forth horizontally; the fixing component is arranged on the base and is located between the two support frames.

[0007] As a preferred solution, there are two processing heads arranged symmetrically left and right, which are respectively arranged on the outer sides of the corresponding support frames. Correspondingly, there are also two first driving mechanisms, and each first driving mechanism drives the corresponding processing head to move horizontally back and forth.

[0008] As a preferred solution, an arc-shaped guiding portion adapted to the opening of the external circular tube is provided at the outer end of the convex portion.

[0009] As a preferred solution, the fixing assembly includes a support base, a pressing rod and a second driving mechanism; the support base is arranged on the base and located between the two support frames, and the upper end of the support base is flush with the bottom of the matching groove; the pressing rod is rotatably and vertically movable above the support base; the second driving mechanism is arranged on the base and drives the pressing rod to move back and forth.

[0010] As a preferred solution, the second driving mechanism is a rotary pressing cylinder.

[0011] As a preferred solution, a strengthening base is arranged on the base, the strengthening base is arranged between the first driving mechanism and the corresponding support frame, and the processing head can horizontally slide through the strengthening base.

[0012] Compared with the prior art, the present utility model has obvious advantages and beneficial effects. Specifically, as can be seen from the above technical solutions:

The grooves are multiple and arranged at equal angles, and the multiple grooves divide the side wall of the processing head into multiple elastic parts. An outer convex part adapted to the inner side wall of the circular tube is integrally protruded on the outer side wall of each elastic part, so that the processing head first extends inward into the circular tube. At this time, the elastic part extends outward and fits with the inner side wall of the circular tube. When the processing head moves outward, the burrs attached to the inner side wall of the circular tube are removed by the convex part. Regardless of the shape of the cut surface of the product, the burrs attached to the inner side wall can be removed, the use limitation is smaller, and the processing requirements of more products can be met.

[0028] Please refer to Figures 1 to 4 as shown, which shows the specific structure of the preferred embodiment of the present utility model, including a base 10, a support frame 20, a processing head 30, a first driving mechanism 40, and a fixing component 50.

[0029] The support frame 20 is arranged on the base 10. There are two support frames 20 arranged symmetrically horizontally. Each support frame 20 is provided with an adaptation groove 201 for cooperating with an external circular tube 60. During processing, the external circular tube 60 is placed in the adaptation grooves 201 on the two support frames 20; in this embodiment, a reinforcing base 11 is arranged on the base 10.

[0030] The processing head 30 is arranged on the base 10 so as to be movable horizontally back and forth and is located outside the support frame 20. The processing head 30 corresponds axially to the position of the fitting groove 201 and cooperates with the external circular tube 60. A through hole 301 with an outer end opening is provided in the processing head 30. A groove 302 is integrally recessed inward on the outer end face of the processing head 30. A plurality of the grooves 302 are arranged at equal angles. The plurality of grooves 302 divide the side wall of the processing head 30 into a plurality of elastic parts 31. An outer convex part 32 that cooperates with the inner side wall of the circular tube 60 is integrally provided on the outer side wall of each elastic part 31. In this embodiment, there are two processing heads 30 arranged symmetrically left and right, and they are respectively arranged outside the corresponding support frames 20. An arc-shaped guiding part 321 that cooperates with the opening of the external circular tube 60 is provided at the outer end of the convex part 32. This guiding part 321 is used to facilitate the process of the processing head 30 entering the interior of the circular tube 60 inward.

[0031] The first driving mechanism 40 is arranged on the base 10 and drives the processing head 30 to move horizontally back and forth; in this embodiment, there are also two first driving mechanisms 40 arranged. Each first driving mechanism 40 drives the corresponding processing head 30 to move horizontally back and forth, so that deburring processing can be simultaneously performed on the cut surfaces at both ends of the circular tube 60. The aforementioned reinforcing seat is arranged between the first driving mechanism 40 and the corresponding support frame 20. The processing head 30 can slide horizontally through the reinforcing seat 11. This reinforcing seat 11 is used to play a certain supporting role for the processing head 30. When the processing head 30 extends out for a long distance, it can ensure the structural stability of the processing head 30.

[0032] The fixing assembly 50 is arranged on the base 10 and is located between the two support frames 20. The fixing assembly 50 is used to fix the circular tube 60 on the two support frames 20, so as to prevent it from sliding left and right and shifting during the processing. In this embodiment, the fixing assembly 50 includes a support seat 51, a pressing rod 52 and a second driving mechanism 53; the support seat 51 is arranged on the base 10 and is located between the two support frames 20, and the upper end of the support seat 51 is flush with the bottom of the fitting groove 201; the pressing rod 52 is arranged above the support seat 51 so as to be rotatable back and forth and movable up and down; the second driving mechanism 53 is arranged on the base 10 and drives the pressing rod 52 to move back and forth. Through the downward pressing of the pressing rod 52 and the cooperation of the support seat 51, the fixing of the position of the circular tube 60 is realized. The second driving mechanism 53 is a rotary pressing cylinder, so that when the circular tube 60 is placed and removed, the pressing rod 52 can be rotated to one side, thus avoiding interference with the pressing rod 52.

[0033] The working principle of this embodiment is described in detail as follows:

[0034] During processing, first place the circular tube 60 in the fitting groove 201 on the two support frames 20. At this time, the circular tube 60 just contacts the support seat 51. Then, the second driving mechanism 53 drives the pressing rod 52 to first rotate to directly above the support seat 51, and then move downward and press tightly on the circular tube 60 to fix the position of the circular tube 60. Then, the first driving mechanism 40 drives the processing head 30 to move towards the cut of the circular tube 60 and enter the inside of the circular tube 60. When it is completely inside, at this time, the convex part on the elastic part 31 is tightly attached to the inner side wall of the circular tube 60 under the action of elastic force. Then, the first driving mechanism 40 drives the processing head 30 to move towards the outer end of the circular tube 60, and removes the burrs tightly attached to the inner side wall of the circular tube 60 through the convex part 32. When the processing head 30 completely moves out, the second driving mechanism 53 drives the pressing rod 52 to reset, and then the circular tube 60 can be taken off.

[0035] The design focus of the present utility model lies in: by providing a support frame and a processing head, and the processing head is arranged on the base so as to be able to move horizontally back and forth. There is a through hole with an open outer end in the processing head. The outer end face of the processing head is integrally concave inwardly with grooves. The grooves are multiple and arranged at equal angles. The multiple grooves divide the side wall of the processing head into multiple elastic parts. The outer side wall of each elastic part is integrally convex outwardly with a convex part that cooperates with the inner side wall of the circular tube. So that it first extends inward into the circular tube through the processing head. At this time, the elastic part extends outward and fits with the inner side wall of the circular tube. When the processing head moves outward, the burrs attached to the inner side wall of the circular tube are removed through the convex part. No matter what shape the cut surface of the product is, it can remove the burrs attached to the inner side wall, with less use limitation and can meet the processing requirements of more products.

[0036] The above is only a preferred embodiment of the present utility model, and does not impose any limitation on the technical scope of the present utility model. Therefore, any minor modification, equivalent change and modification made to the above embodiment according to the technical essence of the present utility model still fall within the scope of the technical solution of the present utility model.
