Abstract
The utility model discloses a plane grinding machine for mobile phone glass. The grinding machine comprises a sun gear, an inner gear ring coaxially arranged with the sun gear and a free-center gear arranged between the sun gear and the inner gear ring, a clamping groove used for fixing glass is formed in the body of the free-center gear, a plurality of teeth are arranged on the outer edge of the free-center gear, the root portion of a tooth groove between every two adjacent teeth is arranged in the shape of an arc, the inner gear ring and the sun gear are provided with pins matched with the root portions of the tooth grooves, and the free-center gear is driven to rotate through the pins. According to the grinding machine, the mode that the pins are meshed with the teeth in a transmission mode to replace the traditional mode that teeth are meshed with teeth in a transmission mode, the service life of the free-center gear can be greatly prolonged, and flat grinding yield of glass products is improved.
Description
Technical field
The utility model belongs to electronic equipment screen glass processing technical field, is specifically related to a kind of mobile phone glass face lapping mill.
Background technology
As everyone knows, the screen glass of the electronic equipment such as mobile phone, computer or flat panel TV need to carry out planar thickness attrition process by grinder.Current grinder, comprise sun gear, with the ring gear of the coaxial setting of sun gear and be arranged on sun gear and ring gear between trip heart wheel.Trip heart wheel meshes with sun gear and ring gear respectively by tooth, by sun gear and ring gear, is rotated simultaneously and is driven trip heart wheel to rotate, and the screen glass being fastened in the middle of trip heart wheel body rubs with upper and lower abrasive sheet under the drive of trip heart wheel, thereby completes grinding.
As previously mentioned, existing trip heart wheel meshes by tooth and sun gear and ring gear, due to its tooth module less (2.5～3), profile of tooth is sharper, trip heart wheel is less with the contact-making surface of gear ring, because trip heart wheel material is glass mat, easily causes biting to trip heart wheel when carrying out cutting engagement with sun gear and ring gear, thereby it is shorter service life to cause swimming heart wheel, need to often change.And, after trip heart foot wheel abrasion, be out of shape easily and in motion process, drawn distortion and cause glass to damage by sun gear and ring gear, cause lower product yield.
Utility model content
Main purpose of the present utility model is to provide a kind of mobile phone glass face lapping mill, is intended to solve in prior art as spent material trip heart wheel shorter technical problem of life-span conventional in glass planar grinding.
The utility model provides a kind of mobile phone glass face lapping mill, comprise sun gear, with the ring gear of the coaxial setting of sun gear, and the wheel of the trip heart between described sun gear and described ring gear, the body of described trip heart wheel is provided with the draw-in groove of establishing mobile phone glass for blocking, the outward flange of trip heart wheel is provided with some teeth, the curved setting of its root of teeth groove between two teeth, described ring gear and described sun gear are provided with the pin coordinating with the root of described teeth groove, by described pin, drive trip heart wheel to rotate.
Preferably, described pin is straight pin or semicircle pin.
Preferably, described pin is embedded on described ring gear and described sun gear.
Preferably, the diameter of described pin is 6～10mm.
Preferably, described pin and described ring gear and described sun gear removably connect.
In the utility model mobile phone glass face lapping mill, the outward flange of trip heart wheel is provided with some teeth, the curved setting of teeth groove of tooth, and ring gear and sun gear are provided with the pin coordinating with the root of teeth groove, by pin, drive trip heart wheel to rotate.Because teeth groove root is arc setting, and pin is mated, and has increased the contact area of trip heart wheel with ring gear, mainly stressed by tooth root part in process of lapping, and stressed the diminishing of tooth top part, therefore life cycle increases, extended the service life of trip heart wheel.After test, improving, can reach 6-10 times before improvement the service life of trip heart wheel.In addition, even if wear and tear, pin turned to or change, without changing whole ring gear or sun gear, having extended the service life of ring gear or sun gear.Further, because the trip heart wheel life-span is longer, the probability that glass damages is lowered, and has promoted the yield of product.
Accompanying drawing explanation
Fig. 1 is the structural representation of mobile phone glass face lapping mill in the utility model one embodiment.
The realization of the utility model object, functional characteristics and advantage, in connection with embodiment, are described further with reference to accompanying drawing.
The specific embodiment
Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
The utility model embodiment provides a kind of mobile phone glass face lapping mill, as shown in Figure 1, this mobile phone glass face lapping mill at least comprise sun gear 1, with the ring gear 2 of the coaxial setting of sun gear 1, and the wheel of the trip heart between described sun gear 1 and described ring gear 23, the body of described trip heart wheel 3 is provided with the draw-in groove 31 of establishing mobile phone glass for blocking, the outward flange of trip heart wheel 3 is provided with the curved setting of teeth groove 33 its root between some tooth 32, two teeth.Ring gear 2 and sun gear 1 are provided with the pin 4 coordinating with teeth groove 33 roots, by pin 4, drive trip heart wheel 3 to rotate.
Concrete, in the utility model embodiment, by sun gear 1 and ring gear 2, rotated simultaneously, by the pin 4 arranging on sun gear 1 and ring gear 2, coordinate with teeth groove 33 roots of trip heart wheel 3, drive the trip heart 3 to rotate, be fastened on the trip heart and take turns 3 screen glass in the middle of bodies and rub with upper and lower abrasive sheet under the drive of trip heart wheel 3, thereby complete grinding.In the utility model embodiment, because teeth groove 33 roots are arc setting, and sell 4, be mated, increased the contact area of trip heart wheel 3 with ring gear 2, mainly stressed by tooth root part in process of lapping, and stressed the diminishing of tooth top part, therefore life cycle increases, extend the service life of trip heart wheel 3, therefore life cycle increases, extended the service life of trip heart wheel 3.After test, improving, can reach 6-10 times before improvement the service life of trip heart wheel 3.
In the utility model embodiment, selling 4 can be arranged on by the mode of inlaying on described ring gear 2 and described sun gear 1.Further, selling 4 removably connects with ring gear 2 and sun gear 1.Because pin 4 and ring gear 2 and sun gear 1 removably connect, even if sell 4, wear and tear, pin 4 is turned to or changed, for example half wearing and tearing of hypothesis pin 4, can, by pin 4 Rotate 180 degree, allow the part that wearing and tearing do not occur coordinate with teeth groove 33 roots; After pin 4 circumference all wear and tear, only need to change pin 4, without changing whole ring gear 2 or sun gear 1, extended the service life of ring gear 2 or sun gear 1.Further, due to the trip heart, to take turns for 3 life-spans longer, and the probability that glass damages is lowered, and has promoted the yield of product.
In the utility model embodiment, the root of teeth groove 33 can be circular arc, sells 4 for straight pin or semicircle pin.
In the utility model embodiment, selling 4 diameter has multiple choices scheme, is preferably 6～10mm.For example, in one embodiment, selling 4 diameter is 6mm; In another embodiment, selling 4 diameter is 8mm; In another embodiment, selling 4 diameter is 10mm.In diameter span explanation the utility model embodiment of above-mentioned pin 4, the modulus value of tooth 32 is relatively large.
These are only preferred embodiment of the present utility model; not thereby limit the scope of the claims of the present utility model; every equivalent structure or conversion of equivalent flow process that utilizes the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
