Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of filter manufacturing, in particular to a filter element upper cover pressure-maintaining tooling. Background Art
[0002] The existing filter element upper cover pressure maintaining tooling is positioned by a guide sleeve installed on the cylinder mounting plate by a guide shaft frame. The cylinder drives the lower pressure plate to press down as a whole. The longer the downward distance, the more unstable the overall structure of the lower pressure plate is, resulting in uncertain contact position when the pressure plate contacts the product upper cover, and occasionally the pressure will be offset, resulting in product scrapping. Summary of the invention
[0003] The utility model provides a filter element upper cover pressure maintaining tooling to overcome the deficiencies of the prior art.
[0004] In order to achieve the above-mentioned purpose, a filter element upper cover pressure maintaining tooling is designed, including a base plate, characterized in that: guide shafts are fixed on both sides above the base plate, a cylinder mounting plate is fixed above the guide shaft, a cylinder is fixed on the cylinder mounting plate, the piston rod of the cylinder is connected to the lower pressure plate, both sides of the lower pressure plate are connected to the guide shaft through linear bearings, a clamping plate is fixed below the lower pressure plate, and a filter element positioning plate is fixed above the base plate.
[0005] The lower pressing plate is provided with a process hole, and the pressing plate is made of a transparent material.
[0006] The cylinder is controlled by a two-hand button.
[0007] The filter element positioning plate is provided with a groove.
[0008] Avoidance holes are provided in the groove of the filter element positioning plate, and the avoidance holes are symmetrically arranged in pairs.
[0009] Compared with the prior art, the utility model adopts a structure of a guide shaft plus a linear bearing, so the overall structure is stable, the repetition accuracy of the pressing position is high, and the deviation and misalignment will not occur. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0017] The utility model is further described below with reference to the accompanying drawings.
[0018] like Figure 1-Figure 6 As shown, guide shafts 2 are fixed on both sides above the base plate 1, a cylinder mounting plate 3 is fixed above the guide shaft 2, a cylinder 4 is fixed on the cylinder mounting plate 3, the piston rod of the cylinder 4 is connected to the lower pressure plate 5, both sides of the lower pressure plate 5 are connected to the guide shaft 2 through linear bearings 6, a clamping plate 7 is fixed below the lower pressure plate 5, and a filter element positioning plate 8 is fixed above the base plate 1. The structure of the guide shaft 2 plus the linear bearing 6 is adopted, and the lower pressure plate 5 as a whole is in any position within the stroke of the cylinder 4 to ensure that the mechanism is stable and reliable without displacement or misalignment. The filter element 9 with the modified upper cover is placed in the filter element positioning plate 8 for positioning, and the cylinder 4 is driven to drive the lower pressure plate 5 to press down, and the pressure is maintained for the set time. When changing the model, you only need to replace the clamping plate 7 and the filter element positioning plate 8.
[0019] The lower pressing plate 5 is provided with a process hole 5-1, and the pressing plate 7 is made of a transparent material. Through the process hole 5-1 and the pressing plate 7, the contact position between the pressing plate 7 and the filter element upper cover can be visually seen, which is convenient for adjustment and ensures the quality of the pressing of the filter element 9.
[0020] Cylinder 4 is controlled by a two-hand button, which improves safety and prevents hands from being pinched during operation.
[0021] A groove 8-1 is formed on the filter element positioning plate 8. The groove 8-1 matches the shape of the filter element 9, and the filter element 9 is placed in the groove to achieve positioning.
[0022] The groove 8-1 of the filter element positioning plate 8 is provided with avoidance holes 8-2, which are arranged symmetrically in pairs. The avoidance holes 8-2 can prevent the protrusion 9-1 of the filter element 9 from interfering with the filter element positioning plate 8. Figure 6 When the filter element 9 has a protrusion 9 - 1 at the lower side as shown, the avoidance holes 8 - 2 symmetrically arranged in pairs can achieve that the direction of the filter element 9 does not need to be distinguished when the product is placed.
[0023] When the utility model is used, the filter element 9 with glue injection and upper cover is placed in the groove of the filter element positioning plate 8 to realize the positioning of the filter element 9; the two-hand button is started to drive the cylinder 4, which drives the lower pressure plate 5 and the clamping plate 7 to be pressed down steadily under the guidance of the linear bearing 6; the clamping plate 7 presses the upper cover of the product and maintains the pressure to the set time, and is automatically unlocked, and the cylinder 4 drives the lower pressure plate 5 and the clamping plate 7 to move up as a whole; the worker takes out the product and flows into the next workstation.
