Description

Technical Field

[0001] The present invention relates to the technical field of filter element processing, and in particular to a method and a device for adjusting the width of a fixture used for filter element processing. Background Art

[0002] It is a professional term for filtering and purification functions. In order to purify the resources of the original fluid and separate the resources, the filter element is mainly used in the filtration industry such as oil filtration, air filtration, and water filtration.

[0003] Currently, during the processing of filter elements, a clamp is usually required to clamp and fix them. However, the existing filter element clamp is usually composed of two baffles and a base plate. The baffles are fixed vertically on the same surface of the base plate to form a U shape. There is a long hole on the base plate. The fixed baffle and screw move along the long hole. After the baffle moves to the appropriate position, the screw is tightened to complete the adjustment. The cumbersome and difficult adjustment is one disadvantage of this clamp. Another disadvantage is that the current clamp is fixed in the installation direction and is difficult to install on a conveyor belt for recycling. As a result, the overall use of the clamp is time-consuming and labor-intensive, and the accuracy is not high. Therefore, a method and device for adjusting the width of the clamp for filter element processing are proposed to solve the above problems. Summary of the Invention

[0015] Preferably, the first baffle and the second baffle have the same orientation, the third baffle and the fourth baffle have the same orientation, the first baffle and the second baffle have opposite orientations to the third baffle and the fourth baffle, and the first baffle, the second baffle, the third baffle and the fourth baffle are all L-shaped.

[0016] Preferably, the adjusting member includes a bidirectional screw fixedly connected to the output shaft of the third servo motor, the outer sides of the bidirectional screw are respectively threadedly connected with a first screw nut and a second screw nut, the outer side of the first screw nut is fixedly connected with a group of first fixing plates, the outer side of the second screw nut is fixedly connected with a group of second fixing plates, and the first fixing plate and the second fixing plate are fixedly connected with a fork at one end away from the bidirectional screw.

[0017] Preferably, the threads on the inner walls of the first screw nut and the second screw nut are symmetrically distributed and matched with the threads on the outer side of the bidirectional screw.

[0018] Preferably, the two first fixing plates and the second fixing plates are both U-shaped, and the ends of the four fork-shaped devices are used to limit the first spline hole synchronization wheel and the third circular hole synchronization wheel, the second spline hole synchronization wheel and the fourth circular hole synchronization wheel, the second circular hole synchronization wheel and the fourth spline hole synchronization wheel, the first circular hole synchronization wheel and the third spline hole synchronization wheel that are in contact with each other on the same side.

[0020] The method for adjusting the width of a fixture for processing a filter element comprises the following steps:

[0021] S1. When the first servo motor is started and drives the first spline shaft to rotate, the first spline hole synchronous wheel and the second spline hole synchronous wheel can be driven to rotate accordingly, so as to drive the first drive structure and the second drive structure to move in the same direction to adjust the position of the first baffle and the second baffle toward the parallel horizontal plane. When the second servo motor is started and drives the second spline shaft to rotate, the third spline hole synchronous wheel and the fourth spline hole synchronous wheel can be driven to rotate, so as to drive the third drive structure and the fourth drive structure to move, so as to drive the third baffle and the fourth baffle to move toward the position parallel to the horizontal plane. The machine controls the distance between the first baffle, the second baffle and the third baffle and the fourth baffle, thereby realizing the adjustment of the overall clamp length.

[0022] S2. By starting the third servo motor to drive the bidirectional screw to rotate, the first screw nut and the second screw nut can be moved in opposite directions for adjustment, thereby driving the two first fixing plates, the second fixing plates and the fork-shaped device as well as the spline hole synchronization wheel and the round hole synchronization wheel attached on the same side to adjust the spacing, thereby realizing the width adjustment of the entire clamp;

[0023] S3. After the horizontal positions of the first baffle, the second baffle, the third baffle and the fourth baffle are adjusted, the first servo motor and the second servo motor can be kept running synchronously at a constant speed to realize the circulation of the fixture, and the first servo motor, the second servo motor and the third servo motor are respectively controlled by the three first servo drive modules, the second servo drive modules and the third servo drive modules on the human-machine interface. The operator only needs to input numerical values ​​on the human-machine interface to control the fixture width at will and accurately.

[0024] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0025] 1. The method and device for adjusting the width of the fixture used for filter element processing realizes precise adjustment of the width of the filter element fixture through precise position control of the servo motor, accurately controls the width and movement of the fixture according to the preset width value, thereby ensuring that the adjustment accuracy of the fixture width reaches the millimeter level or even higher, improving the automation level of the production line and making the preset width more intuitive.

[0026] 2. The method and device for adjusting the width of the fixture used for filter element processing change the cumbersome manual adjustment operation of the existing filter element fixture. It only needs to set parameters through the human-machine interface. By controlling the first servo motor and the second servo motor, the distance between the first baffle, the second baffle, the third baffle and the fourth baffle can be adjusted, that is, it can be easily adjusted to adapt to the width adjustment needs of filter element fixtures of different specifications and sizes. When the product size changes, the fixture width is automatically adjusted without manual re-adjustment of the fixture, and the adaptation can be completed in a short time, which greatly shortens the changeover time of the production line, enables production to quickly switch to the production of the next product, and improves the overall production convenience.

[0027] 3. Compared with traditional manual adjustment fixtures, the method and device for adjusting the width of the fixture used for filter element processing have a rapid and accurate automatic adjustment process, avoiding long downtime and debugging caused by unskilled manual adjustment or errors, thereby ensuring the continuous and stable operation of the production line, effectively improving the equipment's operating rate, and thus improving production efficiency.

[0028] 4. The method and device for adjusting the width of the clamp used for filter element processing can automatically adjust the clamp width and can be adaptively adjusted according to the precise size requirements of different products, ensuring that appropriate and stable clamping force can be provided each time the product is clamped, so that the product can always maintain accurate positioning during the processing or assembly process, effectively reducing the processing error or assembly deviation caused by inaccurate clamp positioning, and improving the dimensional accuracy and consistency of the product.

[0029] 5. The method and device for adjusting the width of the fixture used for filter element processing can meet new production requirements by simply modifying the human-machine interface program or replacing some hardware equipment when the production process or product requirements change, thereby improving the versatility and adaptability of the equipment. The method and device are easy to use and can be operated independently after simple training for operators, reducing dependence on professionals and, to a certain extent, reducing the company's equipment investment costs and labor costs.

[0030] 6. This method and device for adjusting the width of the filter element fixture used in manufacturing allows the entire automated system to automatically record relevant data for each filter element fixture width adjustment, such as adjustment time, adjustment width value, and number of adjustments, through a human-machine interface. This data is extremely valuable for a company's production management and quality control, helping it analyze production process problems, optimize production processes, and improve product quality. This eliminates the inability to access historical data when equipment quality issues arise. This invention can quickly trace back to specific production batches and adjustment parameters, making it easier for companies to identify the root cause of the problem and implement appropriate improvement measures, thereby improving product quality traceability and after-sales service levels.

When the second servo motor 20 is started and the second spline shaft 18 is driven to rotate, and the third spline hole synchronous wheel 11 and the fourth spline hole synchronous wheel 15 are driven to rotate, the third drive structure 10 and the fourth drive structure 14 can be driven to move, so as to drive the third baffle 9 and the fourth baffle 13 to move toward the position parallel to the horizontal plane. The machine controls the spacing between the first baffle 1, the second baffle 5 and the third baffle 9, the fourth baffle 13, and the adjustment of the overall clamp length is achieved.

[0049] In the present invention, the first driving structure 2, the second driving structure 6, the third driving structure 10 and the fourth driving structure 14 can be any one of: chain drive, belt drive, gear drive or screw drive.

[0050] Among them, the specifications of the inner sides of the first spline hole synchronization wheel 3 and the second spline hole synchronization wheel 7 are adapted to the specifications of the outer side of the first spline shaft 17, so that the rotating first spline shaft 17 can drive the first spline hole synchronization wheel 3 and the second spline hole synchronization wheel 7 to rotate synchronously, and the specifications of the inner sides of the third spline hole synchronization wheel 11 and the fourth spline hole synchronization wheel 15 are adapted to the specifications of the outer side of the second spline shaft 18, so that the rotating second spline shaft 18 can drive the third spline hole synchronization wheel 11 and the fourth spline hole synchronization wheel 15 to rotate synchronously.

[0051] In addition, the first baffle 1 and the second baffle 5 have the same orientation, the third baffle 9 and the fourth baffle 13 have the same orientation, the first baffle 1 and the second baffle 5 are in opposite orientations to the third baffle 9 and the fourth baffle 13, the first baffle 1, the second baffle 5, the third baffle 9 and the fourth baffle 13 are all L-shaped, and the L ends of the first baffle 1, the second baffle 5, the third baffle 9 and the fourth baffle 13 are fixed to the drive structure by conventional bolts.

[0052] In an optional embodiment, the output shaft of the third servo motor 21 is provided with an adjusting member for adjusting the spacing between the first drive structure 2, the second drive structure 6, the third drive structure 10 and the fourth drive structure 14, and the adjusting member includes a bidirectional screw rod 22 fixedly connected to the output shaft of the third servo motor 21, and the outer sides of the bidirectional screw rod 22 are respectively threadedly connected with a first screw rod nut 23 and a second screw rod nut 24, and the outer side of the first screw rod nut 23 is fixedly connected with a group of first fixing plates 25, and the outer side of the second screw rod nut 24 is fixedly connected with a group of second fixing plates 26, and the first fixing plate 25 and the second fixing plate 26 are fixedly connected with a fork 31 at one end away from the bidirectional screw rod 22.

[0054] Among them, the threads on the inner walls of the first screw nut 23 and the second screw nut 24 are symmetrically distributed, and are adapted to the threads on the outer side of the bidirectional screw 22, so that the rotating bidirectional screw 22 can drive the first screw nut 23 and the second screw nut 24 to move and adjust toward the opposite or opposite side, that is, to adjust the distance between the first screw nut 23 and the second screw nut 24.

[0055] In addition, the two first fixing plates 25 and the second fixing plates 26 are both U-shaped, and the ends of the four fork-shaped devices 31 are used to limit the first spline hole synchronous wheel 3 and the third circular hole synchronous wheel 12, the second spline hole synchronous wheel 7 and the fourth circular hole synchronous wheel 16, the second circular hole synchronous wheel 8 and the fourth spline hole synchronous wheel 15, the first circular hole synchronous wheel 4 and the third spline hole synchronous wheel 11 that are in contact with each other on the same side. The end of the fork-shaped device 31 is U-shaped, that is, it can be inserted into the outside of the spline shaft without affecting the rotation of the spline shaft.

[0056] The method for adjusting the width of a fixture for processing a filter element comprises the following steps:

[0057] S1. When the first servo motor 19 is started and drives the first spline shaft 17 to rotate, the first spline hole synchronous wheel 3 and the second spline hole synchronous wheel 7 can be driven to rotate accordingly, so as to drive the first drive structure 2 and the second drive structure 6 to move in the same direction to adjust the position of the first baffle 1 and the second baffle 5 toward the parallel horizontal plane. When the second servo motor 20 is started and drives the second spline shaft 18 to rotate, the third spline hole synchronous wheel 11 and the fourth spline hole synchronous wheel 15 can be driven to rotate, so as to drive the third drive structure 10 and the fourth drive structure 14 to move, so as to drive the third baffle 9 and the fourth baffle 13 to move toward the position parallel to the horizontal plane. The machine controls the spacing between the first baffle 1, the second baffle 5 and the third baffle 9, the fourth baffle 13, thereby realizing the adjustment of the overall clamp length.

[0058] S2. By starting the third servo motor 21 and driving the bidirectional screw 22 to rotate, the first screw nut 23 and the second screw nut 24 can be driven to move in opposite directions or opposite directions for adjustment, thereby driving the two first fixing plates 25, the second fixing plate 26 and the fork 31 as well as the spline hole synchronization wheel and the round hole synchronization wheel attached to the same side to adjust the spacing, thereby achieving the width adjustment of the entire clamp;

[0059] S3. After the horizontal positions of the first baffle 1, the second baffle 5, the third baffle 9 and the fourth baffle 13 are adjusted, the first servo motor 19 and the second servo motor 20 can be kept running synchronously at the same speed to realize the circulation of the clamp, and the first servo motor 19, the second servo motor 20 and the third servo motor 21 are respectively controlled by the three first servo drive modules 28, the second servo drive module 29 and the third servo drive module 30 on the human-machine interface 27. The operator only needs to input numerical values ​​on the human-machine interface 27 to control the clamp width at will and accurately.

[0060] The working principle in the above embodiment is:

[0061] The operator inputs the required length and width values ​​of the clamp on the human-machine interface 27, and the first servo drive module 28 and the third servo drive module 30 can accurately and quickly transmit the instructions to the first spline shaft 17 and the second spline shaft 18, and make relevant responses. The human-machine interface 27 can provide the operator with a more intuitive and flexible display, so that the operator can view the clamp values ​​more conveniently and accurately.

[0062] The first servo motor 19 and the second servo motor 20 control the distance between the first baffle 1, the second baffle 5 and the third baffle 9, the fourth baffle 13 to complete the adjustment of the clamp length, and by starting the third servo motor 21, the first fixed plate 25, the second fixed plate 26, the fork 31, the four synchronous wheels, the drive structure, and the baffle are driven to move to achieve the adjustment of the clamp width. When the horizontal orientation of the first baffle 1, the second baffle 5, the third baffle 9, and the fourth baffle 13 meets the requirements, the third circular hole synchronous wheel 12 and the fourth circular hole synchronous wheel 16 move simultaneously to achieve parallel transportation of the clamp. After the overall clamping meets the requirements, the first servo motor 19 and the second servo motor 20 can be kept running synchronously at a constant speed to achieve the circulation of the clamp. During the process, the operator only needs to perform convenient data entry on the human-machine interface 27 to achieve automatic clamp adjustment, without excessive manual operation, saving labor costs, and the entire clamp can be operated in an automated working mode through the operation method, which can improve the clamp accuracy, improve efficiency, and greatly save production time.

[0063] While 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 these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
