Description

Technical Field

[0001] The invention relates to the technical field of aviation rubber product molding, in particular to an eight-position sector-shaped bonded ultra-thin combined filter disc deburring tool and method. Background Art

[0002] A certain type of eight-position sector-shaped bonded ultra-thin combined filter, which is used in a certain type of engine, is an important component of an air separator with a metal chip signal. Its function is to separate the oil from the gas in the lubricating oil and send out an electrical signal when metal appears in the lubricating oil. It is composed of 0.16mm glass fiber reinforced phenolic resin and 0.8mm stainless steel gasket. The phenolic glass fiber pressed plastic of the eight sector-shaped structure is evenly and firmly bonded to the metal gasket.

[0003] This type of eight-position sector-shaped bonded ultra-thin combination filter disc is equipped with 32 pieces per machine, and the annual demand is about 10,000 pieces. After the parts are produced, there are 8 phenolic glass fiber pressed plastic burrs in the middle area of ​​the 8 sector-shaped phenolic glass fiber pressed plastics. The thickness of the burrs is only about 0.2mm, and they are firmly bonded to the thin metal gasket. Because the machining method will cause the stainless steel gasket to deform, and the cured phenolic glass fiber pressed plastic material is brittle and easy to crack, the machining process to remove the residual burrs will cause the phenolic glass fiber pressed plastic to crack and fall into pieces. Therefore, you can only use a file to grind the 8 burrs in small amounts many times. It takes at least 25 minutes for each piece. After a few pieces, the physical exhaustion is serious. After 8 hours a day, less than 20 products are deburred. In addition, manual deburring is easy to damage the phenolic glass fiber pressed plastic area on the parts, and the burrs are unevenly removed, affecting the appearance and quality of the product. Summary of the invention

[0004] Purpose of the present invention: The present invention proposes a deburring device and method for an eight-position sector-shaped bonded ultra-thin combined filter disc, so as to solve the problem that the phenolic glass fiber pressed plastic area on the parts is easily bruised by manual deburring of the eight-position sector-shaped bonded ultra-thin combined filter disc, and the burrs are unevenly removed, thus affecting the appearance and quality of the product.

[0005] Technical solution:

[0006] A deburring device for an eight-position fan-shaped bonded ultra-thin combined filter comprises an upper die and a lower die, wherein a positioning groove is arranged in the middle area of ​​the lower die, and a positioning boss is arranged at the center position of the bottom of the upper die, and the positioning boss and the positioning groove are slidably matched to realize center positioning, and the upper die is a fan structure, comprising eight fan blades arranged at equal intervals around the positioning boss, and the fan blades are fitted one by one with eight glass fiber reinforced phenolic resin areas of the eight-position fan-shaped bonded ultra-thin combined filter.

[0007] Furthermore, the upper die and the lower die are fixed by means of a hexagonal socket.

[0008] Furthermore, a groove with a depth of 0.4 mm is set at the bottom of the fan blade near one end of the positioning boss, and an annular groove with a depth of 0.7 mm is set on the surface of the lower mold. The groove at the bottom of the fan blade and the annular groove of the lower mold form 8 protection areas, and the eight glass fiber reinforced phenolic resin areas of the eight-position fan-shaped bonded ultra-thin combination filter are set in the protection area.

[0009] Furthermore, the thickness of the 8 blades of the upper mold ranges from 4 to 6 mm.

[0010] Furthermore, the thickness of the 8 blades of the upper mold is 5 mm.

[0011] Furthermore, the maximum outer circle of the fan blade is 10mm-11mm larger than the outer circle of the filter, and the part of the fan blade close to the outer circle is an inclined surface, and the angle between the inclined surface and the horizontal line is 30°.

[0012] Furthermore, there is a gap between the protection area and the eight-position sector-shaped bonded ultra-thin combined filter disc, which can be used as a storage trough to store plastic chips generated during deburring.

[0013] Furthermore, the depth of the annular groove on the surface of the lower mold is 0.05 mm less than the thickness of the glass fiber reinforced phenolic resin area of ​​the eight-position sector-shaped bonded ultra-thin combined filter.

[0014] A method for deburring an eight-position sector-shaped bonded ultra-thin combined filter disc, using the device, comprises the following steps:

[0015] Step 1, install the eight-position sector-shaped bonded ultra-thin combined filter into the lower model cavity;

[0016] Step 2, the upper die is matched with the positioning groove of the lower die through the positioning boss, and the eight-position fan-shaped bonded ultra-thin combined filter disc is moved along the circumferential direction, so that the eight fan-shaped glass fiber reinforced phenolic resin areas on the filter disc are matched with the protection area, the eight non-deburred areas are protected, and the other eight areas to be deburred are exposed;

[0017] Step 3: Fasten the upper and lower molds together from top to bottom using the hexagon socket screws.

[0018] Step 4: Use an adjustable speed electric grinder with a conical diamond grinding needle, adjust it to a medium speed, and use a small amount of grinding multiple times to remove large areas of burrs in the 8 areas that need to be deburred. Finally, use the diamond grinding needle tip to fit the edge of the protection area and carefully grind the edge of the filter phenolic glass fiber pressed plastic;

[0019] Step 5: While removing the burrs, push the generated plastic scraps into the storage trough to prevent the plastic scraps from affecting your vision;

[0020] Step 6. After deburring, remove the hexagonal screws and use the air duct to clean the plastic chips on the mold and filter.

[0038] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are 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 making creative work are within the scope of protection of the present invention.

[0039] The features and illustrative embodiments of various aspects of the present invention will be described in detail below. In the detailed description below, many specific details are proposed to provide a comprehensive understanding of the present invention. However, it is obvious to those skilled in the art that the present invention can be implemented without the need for some of these specific details. The following description of the embodiments is only to provide a better understanding of the present invention by illustrating examples of the present invention. The present invention is by no means limited to any specific settings and methods proposed below, but covers any improvements, replacements and modifications of structures, methods, devices without departing from the spirit of the present invention. In the accompanying drawings and the following description, known structures and technologies are not shown to avoid unnecessary ambiguity in the present invention.

[0040] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments can be combined with each other, and the embodiments can refer to and quote each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0041] like Figure 1As shown, the present invention proposes a deburring device for an eight-position fan-shaped bonded ultra-thin combined filter, comprising an upper mold 1 and a lower mold 2, a positioning groove is arranged in the middle area of ​​the lower mold 2, a positioning boss is arranged at the center position of the bottom of the upper mold 1, the positioning boss and the positioning groove are slidably matched to achieve center positioning, the upper mold 1 is a fan structure, comprising 8 fan blades arranged at equal intervals around the positioning boss, and the fan blades are fitted one by one with the eight glass fiber reinforced phenolic resin areas of the eight-position fan-shaped bonded ultra-thin combined filter.

[0042] The deburring device and method for eight-position sector-shaped bonded ultra-thin combined filter discs proposed in the present invention are easy to load and unload, can accurately position the eight-position sector-shaped bonded ultra-thin combined filter discs, and ensure that the phenolic glass fiber pressed plastic of the deburred parts has accurate dimensions and clear and uniform edges; and an electric grinder is used in combination with a conical diamond grinding needle instead of a file, which reduces labor intensity and increases the deburring efficiency by more than 5 times.

[0043] Among them, the upper mold 1 and the lower mold 2 of the eight-position fan-shaped bonded ultra-thin combined filter disc deburring device are both made of P20 material, which is wear-resistant and has a long service life.

[0044] Among them, the upper mold 1 and the lower mold 2 are connected and fixed by the hexagon socket screw 3. The positioning groove and the positioning boss are designed in the middle area of ​​the upper and lower molds 2 for sliding fit, and a center positioning structure is adopted. The center of the mold is connected and fixed with the hexagon socket screw 3, which is easy to disassemble and firmly positioned without affecting the deburring action.

[0045] Among them, the device of the present invention can perfectly match the eight-position fan-shaped bonded ultra-thin combined filter cavity with the phenolic glass fiber pressed plastic area, and can accurately position the filter component to ensure the deburring size and accuracy.

[0046] Among them, a groove with a depth of 0.4mm is set at the bottom of the fan blade near one end of the positioning boss, and a ring groove with a depth of 0.7mm is set on the surface of the lower mold 2. The groove at the bottom of the fan blade and the ring groove of the lower mold 2 form 8 protection areas, and the eight glass fiber reinforced phenolic resin areas of the eight-position fan-shaped bonded ultra-thin combined filter are set in the protection area. The upper mold 1 is designed as a fan structure, and the 8 fan blades are connected to the convex positioning platform in the middle. 8 grooves with a depth of 0.4mm are designed near the positioning platform to facilitate positioning and protection of the 8 fan-shaped glass fiber reinforced phenolic resins on the filter, and at the same time, the area to be deburred is exposed to facilitate the removal of burrs.

[0047] The thickness of the eight blades of the upper mold 1 ranges from 4 to 6 mm, preferably from 5 mm, the maximum outer circle of the blade is 10 to 11 mm larger than the outer circle of the filter disc, and the blade is inclined near the outer circle, and the angle between the inclined surface and the horizontal line is 30°. This can maintain the mechanical strength of the corresponding device of the present invention and avoid the inconvenience of deburring caused by the blade being too thick.

[0048] There is a gap between the protection area and the eight-position sector-shaped bonded ultra-thin combination filter disc, which can be used as a storage tank to store plastic scraps generated during deburring, so as to prevent plastic scraps from covering the filter disc and affecting the deburring sight. The depth of the annular groove on the surface of the lower mold is 0.05mm less than the thickness of the glass fiber reinforced phenolic resin area of ​​the eight-position sector-shaped bonded ultra-thin combination filter disc. This ensures that the area to be deburred is completely exposed to the outside of the device and prevents excessive deburring from damaging the filter disc metal parts.

[0049] The present invention also proposes a method for deburring an eight-position sector-shaped bonded ultra-thin combined filter disc, which is carried out using the device and comprises the following steps:
