Description

Technical Field

[0001] The invention belongs to the technical field of friction plate preparation equipment, and in particular relates to a composite fiber reinforced friction plate surface treatment equipment. Background Art

[0002] In the prior art, the manufacturing method of the friction plate includes the following steps: pulping, papermaking, drying, resin soaking, curing, punching, stamping, heat treatment, surface treatment, surface gluing, patch assembly, and hot pressing. The general process of patch assembly is to glue a single sheet made of a composite material as a substrate onto a skeleton. In this process, the problem of glue overflow is prone to occur, which not only reduces the cleanliness of the surface of the friction plate itself, but also affects the equipment that is in direct contact with the friction plate. If it is not cleaned in time, it will affect the quality of the final product and the life of the equipment. Therefore, how to remove the glue overflow of the friction plate is a technical problem to be solved.

[0003] The document with authorization announcement number CN221983381U discloses a friction material laser degumming device, including a body frame, with rotating rods movably installed on both sides of the left and right sides of the body frame, and wheels movably installed on the front and back sides of the rotating rods, a first installation bin is opened in the middle part of the top of the body frame, a laser control host is movably installed on the left side of the inner cavity of the first installation bin, a connecting pipe is fixedly connected to the left side of the laser control host, and a laser degumming mechanism is fixedly installed on the bottom of the connecting pipe, a second installation bin is opened at the bottom of the body frame, and a cleaning mechanism is movably installed in the inner cavity of the second installation bin.

[0004] However, the above equipment has the following limitations in actual application scenarios: the laser glue removal mechanism has a good cutting effect on glue that is close to solidification, so the device cannot be used immediately after the patch assembly, but needs to wait for the glue to solidify, which is time-consuming; or the glue removal is performed after hot pressing, at which time the glue is completely solidified, but this will cause the overflowed glue to adhere to the surface of the hot press, increasing the difficulty of cleaning.

[0005] To this end, the inventors have proposed a composite fiber reinforced friction plate surface treatment device, which operates after the patch assembly step and is used to immediately remove uncured overflow glue. Summary of the invention

[0006] In view of the above-mentioned problems, the purpose of the present invention is to provide a composite fiber reinforced friction plate surface treatment equipment, which mainly realizes the effect of synchronously removing overflow glue on the inner and outer annular surfaces of the friction plate by means of the clamping effect of the internal and external glue removal structure on the inner and outer sides of the friction plate and the main driving structure driving the internal and external glue removal structures to rotate synchronously.

DETAILED DESCRIPTION

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "inside", "outside", "left", "right", etc. indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings, or are directions or positional relationships in which the product of the invention is usually placed when in use, or are directions or positional relationships commonly understood by those skilled in the art. These directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms such as "setting" and "connection" should be understood in a broad sense. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection: it can be a mechanical connection or an electrical connection: it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0025] The structure of the friction plate a in the present invention is as shown in the attached figure. Figure 1 As shown, it is composed of a skeleton and multiple single-piece friction materials bonded to the skeleton. Among them, the friction material is woven with composite fiber yarns composed of common fibers such as carbon fiber, aramid fiber, glass fiber, etc. to form a bottom layer, and copper fiber yarns are further woven on the surface of the bottom layer, and finally impregnated with resin liquid. The subsequent preparation process includes drying and curing, high-temperature sintering and other commonly used processing processes in this field. The friction material finally obtained has the advantages of high specific strength, stable friction coefficient, excellent wear resistance and heat resistance.

[0026] For glue removal, the glue overflow on the inner and outer sides of the friction plate a has the greatest impact, while the glue overflow on the upper surface of the friction plate a has a smaller impact. The reason is that there are gaps between the single-piece friction materials, or there are grooves on the friction materials, and the glue overflow on the upper surface will preferentially flow to the gaps or grooves, that is, the glue overflow is not easy to contact other equipment components. Therefore, the surface treatment equipment provided by the present invention is mainly aimed at removing glue from the inner and outer annular surfaces of the friction plate. The specific embodiments are as follows: Example 1 As attached Figure 2 and attached Figure 3As shown, a composite fiber reinforced friction plate surface treatment device provided by the present invention is used for removing glue from the inner and outer annular surfaces of a friction plate a, comprising a base 1, an annular boss 2 arranged on the base 1 for placing the friction plate a, a mounting plate 3 arranged at the upper end of the base 1, an inner glue removal structure 4 rotatably arranged on the mounting plate 3 and located at the side end of the inner annular surface of the annular boss 2, a first driving structure 5 arranged on the mounting plate 3 and used to drive the inner glue removal structure 4 to rotate, an outer glue removal structure 6 slidably arranged on the mounting plate 3 and located at the side end of the outer annular surface of the annular boss 2, a second driving structure 7 arranged on the mounting plate 3 and used to drive the outer glue removal structure 6 to approach / move away from the annular boss 2, and a main driving structure 8 arranged on the base 1 and used to drive the mounting plate 3 to rotate; the projection of the rotation center of the mounting plate 3 on the base 1 is located within the inner annular surface of the annular boss 2.

[0027] It is worth noting that the annular boss 2 protrudes from the upper surface of the base 1 to ensure that the annular boss 2 can support the friction plate a at a certain distance away from the upper surface of the base 1, thereby facilitating the operation of the internal and external glue removal structures. The internal glue removal structure 4 and the external glue removal structure 6 are respectively abutted against the inner and outer ring sides of the friction plate a, and move together under the drive of the mounting plate 3, thereby achieving the processing of the overflow of glue at the inner and outer rings of the friction plate a. It should be noted that the main drive structure 8 not only plays the role of driving the mounting plate 3 to rotate, but also has the function of determining the rotation center of the mounting plate 3. Under ideal conditions, the rotation center of the mounting plate 3 coincides with the circular shape of the annular boss 2 and the friction plate a, and at this time, the friction plate a will not move under the working state of the internal and external degumming structures; under actual conditions, due to the different sizes of the friction plates a to be processed, the position of the main drive structure 8 is moved to preferentially ensure that the inner ring side of the friction plate a fits with the internal degumming structure 4, and then the second drive structure 7 is controlled to drive the external degumming structure 6 to move until it fits with the outer ring side of the friction plate a. At this time, the rotation center of the mounting plate 3 is inconsistent with the circle of the friction plate a, but due to the clamping effect of the internal and external degumming structures and the rotation effect of the internal degumming structure 4 itself, the friction plate a itself will move, so that the internal and external degumming structures can still degumming the entire inner and outer ring side of the friction plate a, and the degumming effect will not be reduced. It can be understood that after the internal and external degumming structures fit with the friction plate a, the position of the main drive structure 8 needs to be fixed and remain unchanged, so the main drive structure 8 is preferably detachably connected to the base 1.

[0028] In this embodiment, the main driving structure 8 includes a fixing member 81 connected to the base 1, a first motor 82 arranged on the fixing member 81, a rotating hole 83 arranged on the end of the mounting plate 3 close to the center of the annular boss 2, a rotating shaft 84 arranged on the output end of the first motor 82 and passing through the rotating hole 83, a first external thread section 85 arranged on the rotating shaft 84, and two first limiting nuts 86 screwed on the first external thread section 85 and located on both sides of the mounting plate 3 for fixing the mounting plate 3. Furthermore, the fixing member 81 includes a fixing cylinder 811 arranged on the base 1 and rotatably connected to the rotating shaft 84.

[0029] It is worth noting that the position of the fixing member 81 on the base 1 determines the rotation center of the mounting plate 3, so the lower end of the fixing cylinder 811 is detachably connected to the base 1, and the connection method can be any one of the common connection methods such as snap connection, bolt connection, magnetic adsorption connection, etc. The rotation hole 83 is connected to the rotation shaft 84 to ensure that the mounting plate 3 can be driven to rotate when the rotation shaft 84 rotates. The two first limit nuts 86 are used to fix the position of the mounting plate 3 on the rotation shaft 84 to ensure the rotation stability of the mounting plate 3.

[0030] In this embodiment, the internal glue removal structure 4 includes a mounting hole 41 provided on the mounting plate 3, a first rod body 42 rotatably provided in the mounting hole 41, a first cleaning outer cylinder 43 provided on the outer peripheral side of the end of the first rod body 42 away from the mounting plate 3, a second external thread section 44 provided on the first rod body 42, and two second limiting nuts 45 screwed on the second external thread section 44 and located on both sides of the mounting plate 3 for fixing the mounting plate 3. Among them, the inner diameter of the mounting hole 41 is larger than the outer diameter of the first rod body 42 to avoid friction between the two to affect the rotation of the first rod body 42. The two second limiting nuts 45 are used to fix the position of the first rod body 42 on the mounting plate 3, and will rotate with the rotation of the first rod body 42. The first cleaning outer cylinder 43 is detachably connected to the lower end of the first rod body 42 for easy replacement, and the material can be selected from commonly used cleaning materials such as sponge, cloth, rubber, etc. to ensure a good glue removal effect.

[0031] In this embodiment, the first driving structure 5 includes a first pulley 51 disposed on the end of the first rod body 42 away from the base 1, a driving wheel 52 disposed on the rotating shaft 84, and a transmission belt 53 for connecting the driving wheel 52 and the first pulley 51. Furthermore, the rotation speed of the driving wheel 52 is less than or greater than the rotation speed of the rotating shaft 84, and the rotation direction is the same, or the driving wheel 52 and the rotating shaft 84 have the same rotation speed and opposite rotation directions, or the driving wheel 52 and the rotating shaft 84 have different rotation speeds and opposite rotation directions. The above three different situations of the driving wheel 52 and the rotating shaft 84 can be realized by existing structures such as gears, in order to ensure that the rotating shaft 84 can simultaneously drive the rotation of the mounting plate 3 and the first rod body 42, which cannot be achieved when the driving wheel 52 and the rotating shaft 84 have the same rotation speed and rotation direction.

[0032] In this embodiment, the external glue removal structure 6 includes a strip hole 61 provided on the mounting plate 3, a second rod body 62 slidably connected to the strip hole 61, and a second cleaning outer cylinder 63 provided on the outer peripheral side of the end of the second rod body 62 away from the mounting plate 3. It is worth noting that the material selected for the second cleaning outer cylinder 63 can be the same as that of the first cleaning outer cylinder 43, and the method of detachable connection between the second rod body 62 and the second rod body 62 is preferably end-to-end bonding, which can be achieved by using a parent-child Velcro fastener. The advantage of such a setting is that the difficulty of disassembly is low, the second cleaning outer cylinder 63 can be quickly replaced, and the glue removal effect is prevented from being reduced as the work proceeds. In this embodiment, the second driving structure 7 includes a driving cylinder 71 disposed on the mounting plate 3 and having the same stroke as the strip hole 61, and a clamping member 72 disposed on the end of the driving cylinder 71 and used to fix the end of the second rod body 62. The clamping member 72 is preferably two detachably connected clamps, which facilitates rapid completion of locking with the second rod body 62. The driving cylinder 71 can adopt existing structures such as a cylinder and a hydraulic cylinder, so it is not repeated in this embodiment.

[0033] The working principle of the surface treatment equipment provided in this embodiment is: place the friction plate a on the annular boss 2, adjust the position of the fixing part 81 on the base 1 so that the first cleaning outer cylinder 43 abuts against the inner side surface of the friction plate a, start the second driving structure 7 to adjust the position of the second rod body 62 so that the second cleaning outer cylinder 63 abuts against the outer side surface of the friction plate a, and the two cleaning outer cylinders clamp the friction plate a; start the first motor 82, and the rotating shaft 84 simultaneously drives the rotation of the mounting plate 3 and the first rod body 42, and the two cleaning outer cylinders make a circular motion to synchronously remove the glue from the inner and outer annular surfaces of the friction plate a.

[0034] Example 2 In this embodiment, the structure of the fixing member 81 is optimized on the basis of the embodiment 1. Figure 4 As shown, the details are as follows: The fixing member 81 includes a vertical threaded rod 814 and a vertical guide rod 815 which are arranged on the base 1 and are parallel to each other, a second motor 816 for driving the vertical threaded rod 814 to rotate, a lifting plate 817 which is parallel to the mounting plate 3, a threaded hole 818 which is arranged on the lifting plate 817 and is adapted to the vertical threaded rod 814, and a through hole 819 which is arranged on the lifting plate 817 and allows the vertical guide rod 815 to pass through.

[0035] It is worth noting that the second motor 816 can drive the vertical threaded rod 814 to rotate, and the lifting plate 817 can move up and down under the guidance of the vertical guide rod 815, thereby adjusting the height position of the mounting plate 3, thereby adjusting the height of the two cleaning outer cylinders. The advantage of this arrangement is that the contact area between the two cleaning outer cylinders and the friction plate a can be increased, thereby improving the cleaning effect.

[0036] It is worth noting that at this time, the position of the fixing part 81 on the substrate 1 is fixed. Therefore, in the preparation stage, the lifting plate 817 is first lifted to place the friction plate a on the annular boss 2, and then the lifting plate 817 is lowered to a suitable position, and the position of the friction plate a on the annular boss 2 is adjusted to ensure that its inner annular surface is in contact with the first cleaning outer cylinder 43, and then the position of the second cleaning outer cylinder 63 is adjusted so that the two cleaning outer cylinders clamp the friction plate a.

[0037] As a further preferred embodiment of the present invention, the fixing member 81 further comprises a weight cylinder 812 sleeved on the outside of the fixing cylinder 811, and a third cleaning outer cylinder 813 sleeved on the outside of the weight cylinder 812. The advantage of such a configuration is that the stability of the fixing member 81 is improved, and the third cleaning outer cylinder 813 can also transfer the glue adhered to the first cleaning outer cylinder 43 in real time, thereby improving the service life and cleaning effect of the first cleaning outer cylinder 43.

[0038] Example 3 The difference between this embodiment and embodiment 2 is that Figure 5 As shown, the fixing member 81 does not have the fixing cylinder 811, the weight cylinder 812, and the third cleaning outer cylinder 813. Although this arrangement loses some stability and cleaning effect, it is more conducive to the placement and removal of the friction plate a, so it is practical.

[0039] Example 4 The difference between this embodiment and the second embodiment is that the fixing member 81 only includes the fixing cylinder 811, the counterweight cylinder 812, and the third cleaning outer cylinder 813, and does not include the vertical threaded rod 814, the vertical guide rod 815, the second motor 816, the lifting plate 817, etc. At this time, the fixing member 81 is mainly fixed on the base 1 by the deadweight of the counterweight cylinder 812, and not only the position can be adjusted, but also the stability is good, and it also has good practicality.

[0040] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
