However, since the power assembly reciprocates to push the upper and lower guide rods to move, and the working states of the upper and lower guide rods are opposite, that is, the two clamping assemblies will cause the radiator shell to swing back and forth, so that the sandblasting tube can perform sandblasting and grinding around the hole at multiple angles, and the burrs on the edges of the holes can be better removed.

[0023] The present invention cooperates with structures such as a drilling component and a radiator shell. After the two clamping components clamp the radiator shell, four hydraulic cylinders and motor 1 can be started. The hydraulic cylinder drives motor 1 and the drill bit to rise, and the top of the hydraulic cylinder gradually contacts and supports one side of the two guide blocks, so that they move outward together with the two protective covers respectively. Only then can the drill bit contact and drill holes in the radiator shell. When the drilling component is not in a working state, the spring sheet bounces the protective cover, and the spring sheet and the protective cover on the other side are in the same state, so that the drill bit will not be exposed when not working, thereby preventing the sandblasting tube from causing damage to the drill bit during the sandblasting process, thereby extending the subsequent maintenance cycle of the device.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0034] like Figures 1 to 8 As shown, the present invention provides a drilling tool for radiator processing, including a storage component 1 and a motor 2 7 fixed to the side of the storage component 1, the output shaft of the motor 2 7 is connected to a reciprocating threaded rod 8, and also includes:

[0035] Two clamping assemblies 5 are arranged inside the storage assembly 1, the upper clamping assembly 5 moves inside the storage assembly 1, and the lower clamping assembly 5 is fixed inside the storage assembly 1, and the radiator shell 4 is clamped between the two clamping assemblies 5;

[0036] The storage assembly 1 comprises a working box 11, and a threaded rod 14 is threadedly penetrated through the top of the working box 11;

[0037] The clamping assembly 5 includes an air storage box 51 movably mounted inside the working box 11, the top of the air storage box 51 is mounted on a bearing of the threaded rod 14, a sealing box 59 is arranged inside the air storage box 51, a sealing plate 53 is movably mounted inside the sealing box 59, a derivation rod 52 is fixedly mounted on one side of the sealing plate 53, two tension springs 54 are fixedly mounted on the other side of the sealing plate 53, three cylinders 55 are arranged at equal angles in the annular direction at the bottom of the air storage box 51, a guide rod 56 is movably mounted inside the cylinder 55, and a clamping plate 58 is connected to the bottom of the guide rod 56 through a spring 57;

[0038] The power assembly 2 is fixed to the side of the storage assembly 1, and the motor 2 7 drives the power assembly 2 to reciprocate and push the two derivation rods 52 through the reciprocating threaded rod 8;

[0039] An air supply component 3 is arranged on the power component 2;

[0040] The drilling assembly 6 and the sandblasting tube 9 are arranged inside the storage assembly 1 . There are four sandblasting tubes 9 and four drilling assemblies 6 respectively and they are arranged at four corners of the radiator shell 4 .

[0041] A first chamber is formed between the sealing box 59 and the sealing plate 2 53, and a second chamber is formed between the sealing plate 2 53 and the gas storage box 51. One cylinder 55 passes through the gas storage box 51 and is connected to the first chamber, and the other two cylinders 55 are connected to the second chamber. Two vertical grooves are symmetrically arranged on the inner wall of the working box 11, and the upper gas storage box 51 moves in the vertical grooves.

[0042] The above solution is adopted: since the upper gas storage box 51 moves in the vertical groove, the gas storage box 51 can only move in the vertical direction, and the lower clamping assembly 5 is fixed inside the working box 11, the threaded rod 14 is rotated to press the upper clamping assembly 5 down and clamp the radiator shell 4 together with the lower clamping assembly 5;

[0043] However, the power assembly 2 is started by the motor 2 7 and the reciprocating threaded rod 8, which drives the derivation rod 52 to move, such as Figure 6The derivation rod 52 shown in the figure pulls the sealing plate 2 53 to move to the right, and the air in one of the cylinders 55 is extracted to the first chamber. Similarly, the sealing plate 2 53 squeezes the air in the second chamber to make it enter the two cylinders 55 and force the two guide rods 56 to descend, that is, the guide rod 56 in the cylinder 55 connected to the first chamber descends, and the two guide rods 56 in the two cylinders 55 connected to the second chamber rise. However, due to the reciprocating push of the power assembly 2, the upper and lower derivation rods 52 move, and as shown in FIG. Figure 7 The two derivation rods 52 shown in the figure have the upper derivation rod 52 and the lower derivation rod 52 in opposite working states, that is, the two clamping assemblies 5 will swing the radiator shell 4 back and forth, so that the sandblasting tube 9 can perform sandblasting and grinding at multiple angles around the hole, and the burrs on the edge of the hole can be better removed;

[0044] The clamping plate 58 is connected to the ball shaft of the guide rod 56 and is kept in a horizontal state by the spring 57. This allows the clamping assembly 5 to drive the radiator shell 4 to tilt while the clamping plate 58 can still fit and fix the position of the radiator shell 4, thereby ensuring the stability of the device operation.

[0045] like Figure 1-Figure 4 As shown, the power assembly 2 includes a main air pipe 21 fixedly mounted on the side of the working box 11, the top and bottom of the main air pipe 21 are respectively connected to an air pipe 23 and an air pipe 3 27, the bottom of the air pipe 23 is connected to an air pipe 2 26 via a bellows 25, a protective pipe 24 is movably penetrated through the top of the working box 11, the internal sealing of the main air pipe 21 is clamped with a sealing plate 28, the top and bottom of the main air pipe 21 are respectively connected to two extension boxes 22, and the sealing plate 28 is movable in the extension box 22.

[0046] The sealing plate 1 28 is threadedly connected to the reciprocating threaded rod 8, and the output shaft of the motor 2 7 drives the sealing plate 1 28 to reciprocate in the vertical direction through the reciprocating threaded rod 8.

[0047] The air pipe three 27 is connected to the lower air storage box 51 , the bellows one 25 is located inside the protective tube one 24 , the air pipe two 26 is connected to the inside of the upper air storage box 51 , and the guide rod 52 is sealed and connected to the air pipe two 26 .

[0048] The above scheme is adopted: start the motor 2 7, and its output shaft drives the sealing plate 1 28 to move back and forth in the vertical direction through the reciprocating threaded rod 8. When the sealing plate 1 28 rises, the air inside the main air pipe 21 is squeezed into the air pipe 1 23, and finally pushes the derivation rod 52 to move through the bellows 1 25 and the air pipe 2 26. At the same time, the air below the main air pipe 21 is extracted by the sealing plate 1 28, so that the air in the air pipe 3 27 is extracted and the lower end derivation rod 52 is pulled by the negative pressure. At this time, the two derivation rods 52 are in a staggered moving state, that is, the activity states of the two clamping components 5 are opposite, and can drive the radiator shell 4 to tilt and swing back and forth, and improve the sandblasting effect of the sandblasting tube 9 on the radiator shell 4;

[0049] The threaded rod 14 is rotated to drive the gas storage box 51 to descend and clamp the radiator shell 4. At the same time, the bellows 25 will be pulled and stretched to adapt to the moving position of the gas storage box 51, and the protective tube 24 outside the bellows 25 will always move with the bellows 25, which can reduce the damage of the particles sprayed by the sandblasting tube 9 to the bellows 25 and prevent the internal pressure of the bellows 25 from increasing and causing it to burst;

[0050] Since the sealing plate 28 needs to push the air in the main air pipe 21 to move, and the moving distance is very long, in order to ensure that the main air pipe 21 is still in a sealed state while the sealing plate 28 moves, the upper and lower parts of the sealing plate 28 are both moved in the extension box 22, so that when the power component 2 is working, there will be no leakage, which will cause the working effect of the clamping component 5 to deteriorate.

[0051] like Figure 1 , Figure 2 , Figure 5 As shown, the air supply assembly 3 includes a protective tube 2 34 fixed on the top of the working box 11, and the air pipe 1 23 is connected to the bellows 2 31 through a valve 32. A tension spring 1 33 is arranged inside the bellows 2 31.

[0052] The above scheme is adopted: during the movement of the air storage box 51, the bellows 25 is pulled and stretched, and the air pressure inside it will become low. In order to ensure normal air pressure and that the clamping assembly 5 can better perform the reciprocating tilting work of the radiator shell 4, the valve 32 is opened, and the tension spring 1 33 will pull the bellows 2 31, thereby causing the air pressure inside the bellows 2 31 to enter the bellows 25 and restore the air pressure, further ensuring the working effect of the device.

[0053] like Figure 1-Figure 3 As shown, the storage assembly 1 includes a cover plate 12 hinged to the side of the working box 11, a handle 13 is hinged on the cover plate 12, a lock buckle 16 is fixedly installed on the side of the working box 11, the handle 13 and the lock buckle 16 are in a snap-connected state, and the working box 11 is supported on the ground by a bracket 15.

[0054] The above scheme is adopted: the handle 13 is moved to disengage it from the lock 16. At this time, the cover 12 is in an active state and can be opened. Then, a new radiator shell 4 is placed on the top of the lower clamping assembly 5. Then, the threaded rod 14 is rotated to lower the upper clamping assembly 5 and clamp the radiator shell 4 in conjunction with the lower clamping assembly 5. Similarly, the position of the radiator shell 4 can also be manually adjusted so that the position where the hole needs to be punched is compatible with the drilling assembly 6, thereby improving the convenience of the device.

[0055] like Figure 2 , Figure 7 , Figure 8 As shown, the drilling assembly 6 includes a hydraulic cylinder 61 fixedly mounted inside the working box 11, a motor 62 is disposed on the top of the hydraulic cylinder 61, and a drill bit 63 is connected to the output shaft of the motor 62 in a transmission manner.

[0056] The drilling assembly 6 further includes a protective cover 64 hinged to the inside of the working box 11 . The protective cover 64 is elastically hinged to the working box 11 via a spring sheet 65 . A guide block 66 is disposed inside the protective cover 64 .

[0057] There are two protective covers 64, two spring sheets 65 and two guide blocks 66 respectively, which are symmetrically arranged on both sides of the motor 1 62, and the side of the guide block 66 close to the motor 1 62 is inclined.

[0058] The above scheme is adopted: after the two clamping assemblies 5 clamp the radiator shell 4, the four hydraulic cylinders 61 and the motor 1 62 can be started, the hydraulic cylinder 61 drives the motor 1 62 and the drill bit 63 to rise, and the top of the hydraulic cylinder 61 gradually contacts and supports one side of the two guide blocks 66, so that they move outward together with the two protective covers 64 respectively, and then the drill bit 63 can contact and punch the radiator shell 4. When the drilling assembly 6 is not in a working state, the spring sheet 65 bounces the protective cover 64, and the spring sheet 65 and the protective cover 64 on the other side are in the same state, so that the drill bit 63 will not be exposed when not working, thereby preventing the sandblasting tube 9 from causing damage to the drill bit 63 during the sandblasting process, thereby extending the subsequent maintenance cycle of the device.

[0059] The working principle and use process of the present invention:

[0060] The handle 13 is turned to disengage the lock 16. At this time, the cover plate 12 is in an active state and can be opened. Then, a new radiator shell 4 is placed on the top of the lower clamping assembly 5. The position of the radiator shell 4 is manually adjusted so that the position where the hole needs to be punched matches the drilling assembly 6. Then, the threaded rod 14 is rotated to make the upper clamping assembly 5 descend and clamp the radiator shell 4 in conjunction with the lower clamping assembly 5.

[0061] The four hydraulic cylinders 61 and the motor 1 62 are started. The hydraulic cylinder 61 drives the motor 1 62 and the drill 63 to rise. The top of the hydraulic cylinder 61 gradually contacts and supports one side of the two guide blocks 66, so that the two guide blocks 66 move outward together with the two protective covers 64. The drill 63 contacts and punches holes in the radiator shell 4.

[0062] Start the motor 2 7, and its output shaft drives the sealing plate 1 28 to move back and forth in the vertical direction through the reciprocating threaded rod 8. When the sealing plate 1 28 rises, the air inside the main air pipe 21 is squeezed into the air pipe 1 23, and finally pushes the derivation rod 52 to move through the bellows 1 25 and the air pipe 2 26. At the same time, the air below the main air pipe 21 is extracted by the sealing plate 1 28, so that the air in the air pipe 3 27 is extracted and the lower end derivation rod 52 is pulled by the negative pressure. At this time, the two derivation rods 52 are in a staggered moving state;

[0063] The guide rod 52 pulls the sealing plate 2 53 to move to the right, and the air in one of the cylinders 55 is extracted into the first chamber. The sealing plate 2 53 squeezes the air in the second chamber, causing it to enter the two cylinders 55 and force the two guide rods 56 to descend, that is, the guide rod 56 in the cylinder 55 connected to the first chamber descends, and the two guide rods 56 in the two cylinders 55 connected to the second chamber rise. However, due to the reciprocating movement of the upper and lower guide rods 52 by the power component 2, the working states of the upper guide rod 52 and the lower guide rod 52 are opposite, that is, the two clamping components 5 will cause the radiator shell 4 to swing back and forth, so that the sandblasting tube 9 can sandblast and grind the periphery of the hole at multiple angles.

[0064] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0065] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
