Description

Technical Field

[0001] This utility model relates to the field of filter element end cap pressing technology, specifically a pressing device for filter element end caps. Background Technology

[0002] In the manufacturing process of oil filters, the pressing device plays a crucial role, requiring precise pressing of the end cap and filter element together. A search reveals that most existing filter element end cap pressing devices employ a horizontal pressing method. For example, Chinese Utility Model Patent Application No. 202322375937.4 discloses an oil filter element end cap pressing device, such as... Figure 5 As shown, the device includes a fixed base 13 with two discs 12. In actual use, the oil filter element 8 and the end cap 6 are placed in the middle of the outer wall of the two discs 12. Then, the servo motor is started, which drives the output shaft and the discs 12 to rotate. The rotation of the discs 12 causes the slide column to move towards the center of the discs 12 simultaneously under the vertical guidance of the track and the arc guidance of the arc-shaped through hole, thereby quickly achieving self-centering clamping of the oil filter element 8 and the end cap 6.

[0003] However, in the aforementioned existing technology, the filter element 8 is generally made of paper and is relatively long. When fixing the filter element 8 by placing it horizontally, a considerable force must be applied to clamp it. During this process, the paper filter element 8 is easily damaged, affecting product quality and production efficiency. Furthermore, since the disc 12 stands vertically and is positioned face-to-face, when fixing the filter element 8 and end cap 6, the operator needs to insert the filter element 8 and end cap 6 horizontally into the disc 12. This requires the operator to bend over and turn sideways, which is quite strenuous.

[0004] Therefore, it is necessary to propose a pressing device for filter element end caps to solve the problem that filter elements are easily damaged by clamping due to the filter element structure and disc arrangement in the prior art. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the existing technology by providing a pressing device for filter element end caps to solve the problems in the background technology.

An outer ring is fixed to the lower end of the negative pressure cavity. A negative pressure hole communicating with the negative pressure cavity is provided through the lower end face of the outer ring. A fixing block for inserting into the inner side of the end cap opening is fixed at the center position of the lower end of the negative pressure cavity. Several abutting blocks are slidably provided on the side of the fixing block. The fixing block is equipped with a driving mechanism for driving the abutting blocks to move outward and make tight contact with the inner wall of the end cap.

[0008] Preferably, the driving mechanism includes a drive motor fixed in the negative pressure cavity, a first bevel gear fixed to the output shaft of the drive motor, a sliding groove embedded in the side of the fixing block, a sliding connection between the abutting block and the sliding groove, a screw rotatably disposed in the sliding groove, one end of the screw being threadedly connected to the abutting block, and a second bevel gear meshing with the first bevel gear fixed to the other end of the screw.

[0009] Preferably, the number of the clamping blocks is three, and the three clamping blocks are evenly distributed around the axis of the negative pressure cavity.

[0010] Preferably, the guide rail is provided with a motor screw mechanism for driving the sliding block to move.

[0011] Preferably, a rubber pad is fixed to the lower end face of the outer ring.

[0012] Preferably, the upper surface of the fixing seat is provided with an end cap limiting groove for limiting the end cap.

[0013] Preferably, the limiting device includes two limiting cylinders fixed on the fixed base, and the telescopic ends of the two limiting cylinders are fixed with two limiting plates.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: The pressing device for filter cartridge end caps of this utility model, through the horizontally set guide rail and gripping mechanism, allows the positioning of the end cap and filter cartridge to be performed while standing, without the need for the operator to bend over and turn to the side for positioning; at the same time, the gripping mechanism adopts negative pressure adsorption and clamping block positioning, which can accurately grip and adjust the position of the end cap, and cooperate with the limiting device to limit the filter cartridge, effectively solving the problem of filter cartridges being easily damaged by clamping in the prior art.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model discloses a filter element end cap pressing device, including a fixed base 4. The upper surface of the fixed base 4 is provided with a limiting device 7 for limiting the filter element 8. A horizontally arranged guide rail 10 is fixed to the upper end of the fixed base 4. A sliding block 9 is movably arranged inside the guide rail 10. A telescopic cylinder 2 is fixed to the sliding block 9. A gripping mechanism 3 for gripping the end cap 6 is fixed to the lower end of the telescopic cylinder 2. In use, the filter element 8 is placed on the surface of the fixed base 4 and fixed by the limiting device 7. The end cap 6 is placed on the surface of the fixed base 4. The gripping mechanism 3 grips the end cap 6 and moves it to the upper end of the filter element 8, which facilitates the subsequent pressing steps. The operator can stand and operate the device during the entire operation, which is more convenient. Compared with the prior art, such as the oil filter element end cap pressing device disclosed in Chinese Utility Model Patent Application No. 202322375937.4, this device solves the problem of having to bend over and turn to the side to accurately insert the filter element into the disc 12 during installation.

[0023] In this embodiment, the gripping mechanism 3 includes a negative pressure cavity 31 fixed to the lower end of the telescopic cylinder 2. A negative pressure pipe 37 is provided on the side of the negative pressure cavity 31. The negative pressure pipe 37 can be connected to a vacuum pump to generate negative pressure in the negative pressure cavity 31. An outer ring 32 is fixed to the lower end of the negative pressure cavity 31. A negative pressure hole 33 communicating with the negative pressure cavity 31 is provided through the lower end face of the outer ring 32. A fixing block 34 for inserting into the inner side of the opening of the end cap 6 is fixed at the center position of the lower end of the negative pressure cavity 31. A plurality of abutting blocks 36 are slidably provided on the side of the fixing block 34. The fixing block 34 is equipped with a driving mechanism 35 for driving the abutting blocks 36 to move outward and make tight contact with the inner wall of the end cap 6.

[0024] With the above structure, when gripping the end cap 6, the gripping mechanism 3 is first moved to directly above the end cap 6. Then, the telescopic cylinder 2 extends and drives the negative pressure cavity 31 to move downward, so that the negative pressure hole 33 contacts the upper surface of the end cap 6. Then, the driving mechanism 35 drives the clamping block 36 to move outward. When the clamping block 36 moves outward, it makes close contact with the opening of the end cap 6, thereby adjusting the position of the end cap 6 so that the center of the end cap 6 coincides with the center of the negative pressure cavity 31. Then, the negative pressure pump is started to generate negative pressure, and the end cap 6 is sucked up by the negative pressure.

[0025] like Figure 3 As shown, in one embodiment of this application, the drive mechanism 35 includes a drive motor fixed in a negative pressure cavity 31. The output shaft of the drive motor is fixed with a first bevel gear 351. A groove is embedded in the side of the fixing block 34. The abutting block 36 is slidably connected to the groove. A screw 353 is rotatably provided in the groove. One end of the screw 353 is threadedly connected to the abutting block 36. The other end of the screw 353 is fixed with a second bevel gear 352 that meshes with the first bevel gear 351. In use, when the external power supply of the motor is turned on, the output shaft of the motor rotates, driving the first bevel gear 351 to rotate. When the first bevel gear 351 rotates, it drives the second bevel gear 352 to rotate. When the second bevel gear 352 rotates, it drives the screw 353 to rotate. When the screw 353 rotates, it drives the abutting block 36 to slide in the groove.

[0026] There are three clamping blocks 36, which are evenly distributed around the axis of the negative pressure cavity 31.

[0027] To facilitate the movement of the sliding block 9, the guide rail 10 is equipped with a motor screw mechanism for driving the sliding block 9 to move. The motor screw mechanism is existing technology and will not be described in detail here.

[0028] To increase the sealing performance when the outer arc 31 contacts the end cap 6 and ensure suction, a rubber pad 11 is fixed to the lower end face of the outer ring 31.

[0029] The upper surface of the fixed base 4 is provided with an end cover limiting groove 5 for limiting the end cover 6. The diameter of the end cover limiting groove 5 is larger than the diameter of the end cover 6. The end cover 6 can be placed into the end cover limiting groove 5, and the positioning and gripping functions can be realized by the gripping mechanism 3, which is convenient to use.

[0030] In one embodiment of this application, the limiting device 7 includes two limiting cylinders 71 fixed on the fixed base 4. The telescopic ends of the two limiting cylinders 71 are fixed with two limiting plates 72. When limiting the filter element 8, the filter element 8 is first placed between the two limiting plates 72, and then the limiting cylinders 71 are activated to push the two limiting plates 72 closer to each other and clamp the filter element 8. It can be understood that in this embodiment, the function of the limiting plates 72 is to limit the filter element 8, and it is not necessary to clamp the filter element 8, so the filter element 8 can be well prevented from being damaged.

[0031] In summary, this utility model aims to provide a pressing device for filter element end caps. This device, through a horizontally arranged guide rail 10 and a gripping mechanism 3, allows operators to assemble the filter element 8 and end cap 6 simply by placing the end cap 6 and filter element 8 between the end cap limiting groove 5 and the two limiting plates 72. Compared to the prior art, which requires the end cap 6 or filter element 8 to be horizontally inserted into the disc 12 for fixation, this eliminates the need for bending over and turning sideways, making operation much more convenient. Simultaneously, the gripping mechanism 3 employs negative pressure adsorption and positioning with the clamping block 6, accurately gripping the end cap 6 and adjusting its position. Combined with the limiting device 7, this effectively solves the problem of filter elements being easily damaged when horizontally inserted into the disc 12 for fixation in the prior art.

[0032] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
