Description

Technical Field

[0001] The present invention relates to the technical field of filter opening, and particularly to an automatic filter element hole punching device for filters. Background Art

[0002] A filter is a component that filters impurities or gases through a filter paper. Generally, it refers to an automotive filter, which is a component of an engine. The filter element of the filter is divided into a folded type and a wound type. The wound filter element is formed by winding multiple layers of filter paper outside the core tube. Its filtration area, dirt holding capacity, and service life are much larger than those of the folded type. The wound filter element is ensured the flow of its medium by an external force, and holes need to be evenly opened in the circumferential direction of the core tube to ensure the smooth flow of the filtering medium.

[0003] During the process of opening holes in the core tube, the feeding of the drill bit will generate a radial pressure on the core tube. At this time, the core tube will have a slight deformation, which leads to irregular hole opening. The solution is to reduce the feeding amount and increase the rotation speed to reduce the deformation of the core tube, so as to ensure the hole opening quality. However, as the number of holes opened gradually increases, the anti-deformation ability of the core tube itself will also gradually decline. Even a small amount of feeding will cause deformation of the core tube, ultimately affecting the forming quality of the core tube. Summary of the Invention

Detailed implementation manners

[0032] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0033] Please refer to Figures 1 - 9 , an automatic filter element hole punching device provided by an embodiment of the present invention includes a frame 1, a hydraulic cylinder 2, a slow release mechanism 3 and a base 4. The hydraulic cylinder 2 and the base 4 are connected through the slow release mechanism 3. The base 4 is used for the insertion of the core tube 10, and the hydraulic cylinder 2 is used to drive the core tube 10 to displace in the vertical direction. The hydraulic cylinder 2 has a first state, a second state and a third state according to different extension amounts. It further includes:

[0034] The slow release mechanism 3 includes a first disc 31, a second disc 32 and a first elastic member 34. The second disc 32 is fixedly installed on the output shaft of the hydraulic cylinder 2. The first elastic member 34 is arranged between the first disc 31 and the second disc 32. The base 4 is rotatably connected to the upper part of the first disc 31;

[0035] An anti-deformation assembly, which includes a clamping part 8 and a stop baffle 7. In the first state, the stop baffle 7 is inserted into the core tube 10. In the second state, the core tube 10 presses the clamping part 8, and the clamping part 8 drives the stop baffle 7 to expand so that the stop baffle 7 abuts against the inner wall of the core tube 10;

[0036] A second driving motor 9. In the second state, the second driving motor 9 can drive the core tube 10 to rotate;

[0037] A drilling assembly, which includes a driving part 5, a drill bit 6 and a self-locking structure 57. The driving part 5 is used to drive the drill bit 6 to rotate, and the self-locking structure 57 is used to fix the position of the drill bit 6;

[0038] In the third state, the self-locking structure 57 is unlocked passively, and the drill bit 6 moves towards the direction where the core pipe 10 is located, so that the drill bit 6 drills along the radial direction of the core pipe 10.

[0039] The telescopic movement of the hydraulic cylinder 2 can control the height of the base 4 to change accordingly. The base 4 is rotatably connected to the first disc 31, and the first disc 31 and the second disc 32 are connected by a first elastic member 34. Therefore, during the upward movement, when the first disc 31 is blocked, the first elastic member 34 is compressed. When the first disc 31 is stationary, the second disc 32 can still move. The hydraulic cylinder 2 has a first state, a first state, a second state, and a third state during the extension stroke. In these three states, the height of the second disc 32 gradually increases;

[0040] In the state as shown in the attached Figure 2 figure, at this time, the core pipe 10 can be placed on the base. By extending the hydraulic cylinder 2, the core pipe 10 will move upward until it extends to the first state, so that the stop baffle 7 can be smoothly inserted into the inner wall of the core pipe 10. When changing from the first state to the second state, at this time, as the hydraulic cylinder 2 continues to extend, the core pipe 10 will squeeze the clamping portion 8 upward. As shown in the attached Figure 2 figure, it makes the clamping portion 8 drive the stop baffle 7 to unfold passively, so that a pair of stop baffles 7 respectively abut against both sides of the inner wall of the core pipe 10. At this time, the clamping portion 8 is used in cooperation with the stop baffle 7 to position and clamp the core pipe 10 to ensure the stability during drilling;

[0041] At this time, the rotation of the second drive motor 9 can be used to synchronously drive the core pipe 10 and the base 4 to rotate. By rotating the core pipe 10, holes can be drilled on the circumferential wall of the core pipe 10 by using the drill bit 6;

[0042] After clamping the core pipe 10, the hydraulic cylinder 2 continues to extend, from the second state to the third state. As shown in the attached Figure 5 figure, at this time, the first elastic member 34 is compressed, and the self-locking structure 57 is triggered to unlock during the continuous upward movement of the first disc 31. After unlocking, the drill bit 6 moves towards the direction where the core pipe 10 is located, so that the drill bit 6 drills along the radial direction of the core pipe 10. During drilling, due to the supporting effect of the stop baffle 7, the core pipe 10 will not deform, making the hole size standard and improving the forming quality. And compared with the existing small feed and high speed in the technology, the feed amount of the drill bit 6 is large, reducing the drilling time. The low speed of the drill bit 6 can significantly reduce heat generation and avoid the hole from being charred at high temperature.

[0043] After the drilling is completed, the core tube 10 needs to be turned over to facilitate drilling at the next position. The hydraulic cylinder 2 is retracted from the third state to the second state, and the second disc 32 is used to drive the drilling assembly to reset, so that the drill bit 6 is separated from the core tube 10. When the second drive motor 9 is rotated, the clamping part 8 can be driven to rotate. Synchronously, the core tube 10 and the base 4 rotate synchronously. After rotating a certain angle, the hydraulic cylinder 2 continues to retract, so that the core tube 10 does not pressurize the clamping part 8, so that the clamping part 8 will drive a pair of stop plates 7 to separate from the core tube 10. At this time, the second drive motor 9 can be rotated to make the stop plates 7 rotate synchronously, and the stop plates 7 can correspond to the drill bit 6 again. In this way, it is ensured that the stop plates 7 can still support the core tube 10 during the drilling process next time.

[0044] In the embodiments of the present invention, please refer to Figure 1 , Figure 2 , Figure 7 and Figure 8 The clamping portion 8 includes an end cover 81, a displacement block 82, a lifting rod 83, a limit frame 84, and a pulling arm 85. The limit frame 84 is fixedly mounted on the end cover 81, the displacement block 82 is slidably connected in the limit frame 84, the displacement block 82 and the stop plate 7 are fixedly connected, one end of the pulling arm 85 is hinged on the displacement block 82, and the other end of the pulling arm 85 is hinged on the lifting rod 83, the lifting rod 83 slides through the limit frame 84, and the upper end of the lifting rod 83 is fixedly mounted on the output shaft of the second drive motor 9.

[0045] During the upward displacement of the core tube 10, the stop plate 7 will first be inserted into the inner wall of the core tube 10, and the core tube 10 will be continuously driven upward by the hydraulic cylinder 2. The core tube 10 will squeeze the end cover 81, and the end cover 81 will be displaced upward under the force. The end cover 81 will be displaced upward while the position of the lifting rod 83 remains unchanged. Synchronously, the height of the displacement block 82 will move upward, and the tension arm 85 will rotate. When the tension arm 85 rotates, a thrust will be applied to the displacement block 82, so that the displacement block 8 2 will drive the stop plate 7 to expand outwards, and the stop plate 7 will contact the inner wall of the core tube 10 after expanding outwards, and the core tube 10 is positioned and supported by the stop plate 7, so that the core tube 10 is automatically clamped and positioned to improve the stability of the core tube 10 during drilling. The position of the stop plate 7 corresponds to the drill bit 6. When drilling, the core tube 10 is supported in the radial direction by the stop plate 7, which can avoid the deformation of the core tube 10 during the drilling process and improve the hole forming quality.

[0046] See also Figure 7 The stop plate 7 is provided with a through hole, and the position of the through hole corresponds to the drill bit 6. By providing a through hole corresponding to the drill bit 6 on the stop plate 7, the drill bit 6 can smoothly penetrate the through hole when rotating the hole, so as to make way for the drill bit 6.

[0047] In an embodiment of the present invention, refer to Figures 1 - 6 and Figure 9 , the driving part 5 includes a sliding frame 51, a chuck 61, a second elastic member 53, a belt 54, a first driving motor 55, and a release block 56. The sliding frame 51 is slidably connected to the frame 1, the chuck 61 is rotatably connected to the sliding frame 51, and a plurality of the chucks 61 are drivingly connected by the belt 54. The drill bit 6 is clamped in the chuck 61. The first driving motor 55 is used to drive the chuck 61 to rotate. The release block 56 is fixedly installed at the bottom of the sliding frame 51, and the second elastic member 53 applies a thrust to the sliding frame 51 towards the center of the frame 1. The self-locking structure 57 includes a centering shaft 571, a third elastic member 572, a movable block 573, a pin block 574, and a trigger block 575. The centering shaft 571 is fixedly installed on the sliding frame 51, the movable block 573 is slidably sleeved on the centering shaft 571, the third elastic member 572 is sleeved on the centering shaft 571, the pin block 574 is fixedly installed at one end of the movable block 573, and the trigger block 575 is fixedly installed at the other end of the movable block 573. The release block 56 has an inclined surface section 561 and a vertical section 562. In the second state, the second disc 32 contacts the vertical section 562, and in the third state, the second disc 32 abuts against the inclined surface section 561.

[0048] The sliding frame 51 is slidably connected to the frame 1, and the second elastic member 53 always applies a thrust to the sliding frame 51. The chuck 61 is rotatably connected to the sliding frame 51, and the drill bit 6 is clamped by the chuck 61. Therefore, when the sliding frame 51 undergoes a horizontal displacement, the drill bit 6 can be driven to displace synchronously. A pulley is provided outside the chuck 61, so that the chuck 61 can be driven by the belt 54 in cooperation with the pulley to achieve synchronous rotation of multiple drill bits 6. The output shaft of the first driving motor 55 is fixedly connected to one of the chucks 61. In this way, the first driving motor 55 can be used to drive the chuck 61 to rotate to achieve synchronous rotation of the drill bits 6. The first driving motor 55 is fixedly installed on the sliding frame 51. Therefore, when the sliding frame 51 undergoes a displacement, the first driving motor 55 moves synchronously;

[0049] The self-locking structure 57 is arranged on the sliding frame 51, attached Figure 3As shown, a downward thrust is always applied to the movable block 573 by the third elastic member 572, so that the movable block 573 is located at the lower part of the sliding frame 51. The pin block 574 is fixed to one end of the movable block 573, and the lower part of the pin block 574 is embedded in the frame 1. In this way, the transverse movement of the sliding frame 51 is resisted by the pin block 574, and the position of the sliding frame 51 is fixed by the pin block 574. The sliding frame 51 is restricted and cannot displace towards the center of the frame 1. As the hydraulic cylinder 2 extends, the first disc 31 presses against the trigger block 575, and the trigger block 575 displaces upward against the elastic force of the third elastic member 572. The pin block 574 disengages from the frame 1. In the appendix Figure 4 In the figure, at this time, the hydraulic cylinder 2 is in the second state. The first disc 31 abuts against the trigger block 575, forcing the trigger block 575 to move upward. At this time, the pin block 574 disengages from the frame 4. At this time, the second disc 32 just abuts against the release block 56. The second disc 32 abuts against the vertical section 562. At this time, the movement of the sliding frame 51 is restricted by the release block 56. As the hydraulic cylinder 2 continues to extend, the hydraulic cylinder 2 reaches the third state. At this time, as shown in the appendix Figures 5 - 6 As shown, the second disc 32 contacts the inclined section 561. Due to the inclined setting of the inclined section 561, at this time, under the elastic force of the second elastic member 53, the sliding frame 51 will displace towards the location of the core pipe 10, and the drill bit 6 will contact the core pipe 10 and drill it. According to the different extension amounts of the hydraulic cylinder 2, the automatic feeding of the drill bit 6 is controlled, and no additional operation is required. Compared with the traditional manual control, during the loading and unloading process, the possibility of the movement of the drill bit 6 is completely eliminated, so the safety is greatly improved during the loading process.

[0050] After the drilling is completed, the core pipe 10 needs to be flipped to drill at the next position. By lowering the hydraulic cylinder 2, the hydraulic cylinder 2 retracts from the third state to the second state. When the hydraulic cylinder 2 retracts, the height of the second disc 32 decreases, and the second disc 32 will change from the appendix Figure 5 shown to as shown in the appendix Figure 4As shown, in this process, first, the height of the second disc 32 decreases. The second disc 32 will squeeze the release block 56, and the second disc 32 moves from the inclined plane section 561 to the vertical section 562. At this time, the release block 56 drives the sliding frame 51 to reset. After the sliding frame 51 is reset, the drill bit 6 will disengage from the core pipe 10. By rotating the second drive motor 9, the clamping part 8 can be driven to rotate. Since at this time, the stop baffle 7 and the core pipe 10 are in close contact, under the action of friction, synchronously, the core pipe 10 and the base 4 rotate synchronously. After rotating a certain angle, it stops. The hydraulic cylinder 2 continues to retract, so that the core pipe 10 does not squeeze the end cover 81. In this way, the clamping part 8 will retract, and the clamping part 8 drives a pair of stop baffles 7 to disengage from the core pipe 10. At this time, the second drive motor 9 can be rotated, so that the stop baffles 7 rotate synchronously, and the stop baffles 7 can correspond to the drill bit 6 again. In this way, without manually adjusting the position of the core pipe 10, the core pipe 10 can be evenly drilled on the circumferential surface.

[0051] Please refer to Figure 3 , a groove adapted to the pin block 574 is formed on the frame 1. In the first state, the pin block 574 is embedded in the groove. The setting of the groove enables the pin block 574 to be embedded in the frame 1 to fix the sliding frame 51.

[0052] Please refer to Figure 7 , the second drive motor 9 is fixedly installed on the top of the frame 1, and the output shaft of the second drive motor 9 penetrates through the upper part of the frame 1. The rotation of the second drive motor 9 can synchronously drive the lifting rod 83 to rotate, thereby changing the angle of the clamping part 8.

[0053] Please refer to Figure 2 , the upper part of the first elastic member 34 is fixedly installed on the first disc 31, and the lower part of the first elastic member 34 is fixedly installed on the second disc 32. The first elastic member 34 exerts an upward thrust on the first disc 31.

[0054] Please refer to Figure 2 , further comprising a telescopic sleeve 33. The upper part of the telescopic sleeve 33 is fixedly installed on the first disc 31, and the lower part of the telescopic sleeve 33 is fixedly installed on the second disc 32. The setting of the telescopic sleeve 33 can limit the first disc 31 and the second disc 32, and the first disc 31 and the second disc 32 can only change their heights in the vertical direction.

[0055] The height of the stop baffle 7 is adapted to the height of the core pipe 10. In this way, when the extrusion force is large, by the stop baffle 7 abutting against the base 4, deformation caused by excessive axial pressure can be avoided.

[0056] Only certain exemplary embodiments of the present invention have been described by way of illustration, and it is understood that, without departing from the spirit and scope of the present invention, various modifications can be made to the described embodiments by those of ordinary skill in the art. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of the claims of the present invention.
