Description

Technical Field

[0001] This invention relates to the field of eyeglass manufacturing technology, and in particular to a processing technology for elastic hinges for eyeglasses. Background Technology

[0002] To make eyeglasses more comfortable and convenient to wear, manufacturers and designers usually incorporate a spring hinge into the folding part of the glasses, where the temples meet the frame.

[0003] For example, patent CN208314361U discloses a spring hinge for eyeglasses, belonging to the field of eyeglasses manufacturing technology. It solves problems such as poor support in existing eyeglasses spring hinges. This eyeglasses spring hinge includes a housing, a spring, a core, and a blocking member. The housing has a cavity, and one end of the housing has a plug hole communicating with the cavity. The core includes a head, a middle section, and a tail section. The middle and tail sections are located within the housing, and the plug hole guides the middle section. The head section extends out of the housing and has a hook and a hinge hole. The spring is fitted onto the tail section, and the end of the tail section has a stop for the inner end of the spring to abut. The blocking member passes through the tail section, and the end of the blocking member facing the plug hole has an outwardly protruding blocking piece. The inner wall of the housing has a groove for the blocking piece to be embedded. The outer end of the spring acts on the blocking member to provide elastic force, and the rigidity or elasticity of the blocking piece itself ensures that the blocking piece always tends to be embedded in the groove. This utility model has the advantages of simple structure and good support.

[0004] However, the applicant found that to obtain the groove portion inside the housing for the insertion of the blocking plate, precise grooving of the inner wall of the housing is required. However, due to the small space inside the housing, it is difficult to control the cutting accuracy in actual grooving operations, which can easily lead to the scrapping of the housing. There is an urgent need for an elastic hinge with a simple structure, easy processing and good support. Summary of the Invention

[0005] In view of the shortcomings of the existing technology, the purpose of this invention is to provide a processing technology for elastic hinges for eyeglasses.

[0006] The technical solution of this invention is implemented as follows: a manufacturing process for an elastic hinge for eyeglasses, comprising the following steps:

[0007] S1. Remove the shell blank;

[0008] S2. Cut the shell blank into shape;

[0009] S3. Perform a tumble burnishing process on the cut blank.

[0010] S4. After cleaning, install it on a milling machine and mill it into shape;

[0011] S5. Place the milled blank on the hole-opening device and open a plug hole at its end. Then, open a first locking hole through one side wall of the plug hole at the lower end of the blank through the hole-opening device. Then, open a second locking hole coaxial with the first locking hole through the first locking hole on the other side wall of the plug hole through the hole-opening device.

[0012] S6. Clean and dry the milled housing;

[0013] S7. Insert the core into the housing for assembly;

[0014] S8, stability test, warehousing.

[0015] By adopting the above technical solution, compared with the grooves produced by transmission boring, the side-opening clasp of the housing has a visual operation, is simple to operate, and is easy to process, effectively improving processing efficiency and yield. It can quickly prepare housings for assembly with the core. Compared with manual positioning drilling of transmission, it is more efficient and practical, effectively improving production efficiency and having good practical effect.

[0026] By adopting the above technical solution, the operator only needs to place the milled blank without drilling on the feeding device. The blank is then fed into the fixed seat on the turntable and fixed. Then, the servo motor drives the turntable to rotate, causing the fixed seat to enter the drilling station. The first drilling device drills plug holes at the end of the blank, and the second drilling device performs side hole processing on the blank. After processing, the servo motor drives the turntable to move the fixed seat into the slag discharge station for plug hole cleaning. Then, the blank enters the unloading workpiece and the cleaned shell is discharged into the receiving box for collection. The usage effect is good.

[0028] The slot is located on the side of the fixed base away from the central axis of the turntable;

[0029] The first through slot is formed on the lower wall of the slot, and the lower end of the turntable is provided with a second through slot connected to the first through slot.

[0030] Several air extraction holes are located at the bottom of the slot.

[0031] By adopting the above technical solution, the slot is used to insert the blank, and then air is extracted through multiple air extraction holes to firmly attach the blank to the fixed base, resulting in good performance.

[0032] The present invention is further configured such that: the first drilling device includes:

[0033] The first hydraulic lifting platform is fixedly installed on the inner wall of the machine body, and the movement trajectory of the output end of the first hydraulic lifting platform is parallel to the ground.

The second hydraulic lifting platform is fixedly installed on the lower end face of the machine body, and the second electric drill is fixedly installed on the upper end of the second hydraulic lifting platform. The extension line of the axis of the output end of the first electric drill intersects and is perpendicular to the extension line of the axis of the output end of the second electric drill.

[0036] By adopting the above technical solution, end holes and side holes can be quickly made on the blank, which can effectively improve production efficiency and reduce labor costs.

[0037] The present invention is further configured such that the opening device also includes:

[0038] The drive belt is located on the left side of the machine body.

[0039] Several miniature material-bearing cylinders are fixedly installed on the transmission belt and are equidistantly spaced along the length of the transmission belt.

[0042] By adopting the above technical solution, the blank can be placed in a miniature material support cylinder, making it less likely to deviate when the blank is conveyed on the conveyor belt, and the edge robotic arm clamps the blank and inserts it into the slot of the fixed seat.

[0043] The present invention is further configured such that: the turntable includes:

[0044] The first fixed plate includes a rotating ring and a lower fixed plate fixedly installed at the lower end of the rotating ring.

The upper end face of the rotating ring abuts against the bottom of the annular groove. The rotating ring is provided with a first air extraction chamber and an air filling chamber at intervals along its circumference. The upper ends of the first air extraction chamber and the air filling chamber are open. The first air extraction chamber is located in the interval between the loading station, the drilling station and the slag discharge station. The air filling chamber is located in the interval between the unloading station.

[0045] The second fixed plate is fixedly installed on the upper surface of the turntable;

[0046] Several second suction chambers are circumferentially spaced within the second fixed plate, and ventilation holes penetrating the bottom of the annular groove are provided on the lower wall of the second suction chamber.

[0047] The system includes an inflation chamber connected to an external inflation pump, a first suction chamber connected to an external suction pump, and a fixed base corresponding to a second suction chamber. The suction port of the fixed base is connected to its corresponding second suction chamber via a suction pipe. When the fixed base is located within the area of ​​the loading station, drilling station, and slag discharge station, the vent of its corresponding second suction chamber is located directly above the first suction chamber, and the second suction chamber is under negative pressure. When the fixed base is located within the area of ​​the unloading station, the vent of the second suction chamber is located directly above the inflation chamber, and the second suction chamber is under positive pressure.

[0048] By adopting the above technical solution, the blank is firmly adsorbed in the fixed seat in the interval between the loading station and the slag discharge station, preventing the blank from loosening during transportation or processing and causing it to fall or produce processing errors. Then, it passes through the unloading station. At this time, the second air extraction chamber corresponding to the unloading station is connected to the air filling chamber. The second air extraction chamber located in the unloading station interval is in a positive pressure state. High-pressure air pushes the blank in the fixed seat out through the air extraction hole. The pushed-out blank will fall into the receiving box below. The structure is simple and the use effect is good.

[0049] The present invention is further configured such that the filter cake device includes:

[0050] The receiving box is fixedly installed on the upper edge of the servo motor, and a support rod is fixedly installed between the receiving box and the lower fixed plate.

[0051] The first liquid inlet is located on the left side wall of the container;

[0052] The filter tube is fixedly installed inside the housing box on the left side by bolts;

[0053] The filter cylinder is located inside the filter tube.

[0054] The screw is located inside the filter cylinder. The upper end of the screw passes through the filter cylinder and the filter tube in sequence and protrudes from the upper end of the filter tube, where it is connected to the first umbrella-shaped tooth.

[0055] A micro motor is fixedly installed on the left side of the receiving box. The output end of the micro motor extends through the receiving box into the receiving box and is keyed to a second bevel tooth that meshes with the first bevel tooth.

[0056] The first partition is fixedly installed at the lower end of the filter cylinder. The edge of the first partition abuts against the inner wall of the filter tube. The first partition has a first liquid outlet hole in the middle.

[0057] The second partition is integrally formed in the middle of the filter tube body. The middle of the second partition has a through hole for the filter tube body to pass through, and the outer wall of the filter tube body abuts against the wall of the through hole.

[0058] A rotating ring is fixedly installed in the middle of the upper end of the filter cylinder, and the rotating ring is provided with an internal thread that is threaded to the screw.

[0059] The outer diameter of the filter cylinder is smaller than the inner diameter of the filter tube. A second liquid inlet is provided on the outer side of the filter cylinder, which is connected to the first liquid inlet. The horizontal height of the second liquid inlet is higher than the horizontal height of the upper surface of the first partition. There is a gap between the first partition and the lower surface of the filter cylinder. A second liquid outlet is provided at the lower end of the filter cylinder. A slag discharge hole is provided on the right side wall of the receiving box. The slag discharge hole is at the same horizontal height as the second liquid inlet. The horizontal height of the lower end of the second partition is higher than the horizontal height of the second liquid inlet.

[0060] By adopting the above technical solution, the support rod limits the first fixed plate. By setting up a slag filter device, the cutting fluid mixed with copper slag washed down from the slag discharge station can be filtered and cleaned. The micro motor and screw can drive the filter cylinder to rotate and descend, increasing the filtration area and continuously changing the position of the impact part of the filter cylinder located on the right side of the second liquid inlet to avoid continuous impact, blockage and aging, and prevent the filter screen from clogging. The filtered cutting fluid enters the first liquid outlet pipe through the first liquid outlet and the second liquid inlet and is then extracted and discharged for reuse, with good performance.

[0061] The present invention is further configured such that the filter cake device also includes:

[0062] The first outlet tube is located inside the container;

[0063] The slag suction cylinder is horizontally fixedly installed in the receiving box and located on the right side of the filter cylinder. The slag suction cylinder includes a first cylinder and a second cylinder that are interconnected. The outer diameter of the first cylinder is larger than the outer diameter of the second cylinder. From bottom to top, a first slag discharge pipe and a second slag discharge pipe that are connected to the first cylinder are fixedly installed on the end of the first cylinder away from the second cylinder. The liquid inlet end of the first slag discharge pipe is fixedly connected to the slag discharge hole.

[0064] The first plug is slidably connected to the first cylinder, and an elastic element is connected between the first plug and the right side wall of the first cylinder.

[0065] The second plug is slidably connected to the inside of the second cylinder;

[0066] The first electric telescopic rod is fixedly installed on the right side of the receiving box. The output end of the first electric telescopic rod passes through the receiving box and the second cylinder in sequence and is fixedly connected to the second plug.

One-way valves are installed in the first slag discharge pipe, the second slag discharge pipe, the first outlet pipe and the second outlet pipe.

[0068] By adopting the above technical solution, under normal conditions, the first plug is confined to the middle of the first cylinder by the elastic element and is not affected by the piston movement of the second plug. The first electric telescopic rod drives the second plug to perform piston movement in the second cylinder, drawing the cutting fluid from the first inlet pipe into the second cylinder and then discharging it through the second outlet pipe. The separated copper shavings are trapped in the area between the first and second partitions. When the filter screen between the first and second partitions is blocked, the first electric telescopic rod drives the second plug to extend into the first cylinder and push the first plug to the left. Afterwards, the second plug retracts, and the first plug resets due to the elastic force of the elastic element, creating a negative pressure on the left side of the first cylinder to draw copper shavings from the area between the first and second partitions into the first cylinder. The elastic element is a highly elastic spring or sheet. Then, the second plug extends again, pushing the first plug to squeeze the copper shavings into the second slag discharge pipe and then discharge them. Afterwards, the micro motor starts to increase the filtration range of the filter cylinder, and the second plug moves again in the second cylinder to draw in the cutting fluid. The one-way valve prevents backflow in the pipelines during transportation, resulting in good performance.

[0069] The present invention is further configured to include:

[0070] The second electric telescopic rod is fixedly installed at the lower end of the first fixed plate and located within the slag discharge station;

[0071] The cutting fluid spray nozzle includes a first horizontal pipe, a second horizontal pipe, and a vertical pipe for connecting the first horizontal pipe and the second horizontal pipe. The second horizontal pipe is attached to the output end of the second electric telescopic rod. The cutting fluid spray nozzle is made of stainless steel. A hose is connected between the input end of the second horizontal pipe and the output end of the second outlet pipe. The horizontal height of the first horizontal pipe is equal to the horizontal height of the first electric drill bit.

[0072] When the second electric telescopic rod retracts, the output end of the first horizontal tube is inserted into the plug hole of the housing located in the fixed seat at the slag discharge station. The lower end of the machine body is equipped with a liquid receiving box and a slag discharge box. The upper end of the liquid receiving box is normally open and located directly below the slag discharge station. A liquid inlet pipe is connected between the first liquid inlet and the bottom of the liquid receiving box. The output end of the second slag discharge pipe is connected to the slag discharge box.

[0073] By adopting the above technical solution, the shell after drilling can be cleaned quickly. The cutting fluid mixed with copper shavings flows into the receiving tank through the second channel or the edge of the turntable. Then, the cutting fluid mixed with copper shavings in the receiving tank is extracted, filtered, and then transported back to the cutting fluid spray pipe. The discharged copper shavings enter the slag discharge box for sedimentation and separation. The structure is simple and the effect is good. Attached Figure Description

At this time, the second suction chamber is in a positive pressure state.

[0140] By adopting the above technical solution, the blank is firmly adsorbed in the fixed seat in the interval between the loading station and the slag discharge station, preventing the blank from loosening during transportation or processing and causing it to fall or produce processing errors. Then, it passes through the unloading station. At this time, the second air extraction chamber corresponding to the unloading station is connected to the air filling chamber. The second air extraction chamber located in the unloading station interval is in a positive pressure state. High-pressure air pushes the blank in the fixed seat out through the air extraction hole.

[0156] This embodiment provides a manufacturing process for an elastic hinge for eyeglasses. In addition to the technical solutions described in the above embodiments, it also has the following technical features.

[0157] In this embodiment of the invention, the filter residue device further includes:

[0158] The first liquid outlet tube 40 is located inside the receiving box 30;

[0159] The slag suction cylinder is horizontally fixedly installed inside the receiving box 30 and located on the right side of the filter cylinder 33. The slag suction cylinder includes a first cylinder 41 and a second cylinder 42 that are connected to each other. The outer diameter of the first cylinder 41 is larger than the outer diameter of the second cylinder 42.

[0164] By adopting the above technical solution, under normal conditions, the first plug is confined to the middle of the first cylinder by the elastic element and is not affected by the piston movement of the second plug. The first electric telescopic rod drives the second plug to perform piston movement in the second cylinder, drawing the cutting fluid from the first inlet pipe into the second cylinder and then discharging it through the second outlet pipe. The separated copper shavings are trapped in the area between the first and second partitions. When the filter screen between the first and second partitions is blocked, the first electric telescopic rod drives the second plug to extend into the first cylinder and push the first plug to the left. Afterwards, the second plug retracts, and the first plug resets due to the elastic force of the elastic element, creating a negative pressure on the left side of the first cylinder to draw copper shavings from the area between the first and second partitions into the first cylinder. The elastic element is a highly elastic spring or sheet. Then, the second plug extends again, pushing the first plug to squeeze the copper shavings into the second slag discharge pipe and then discharge them. Afterwards, the micro motor starts to increase the filtration range of the filter cylinder, and the second plug moves again in the second cylinder to draw in the cutting fluid. The one-way valve prevents backflow in the pipelines during transportation, resulting in good performance.
