Description

Technical Field

[0001] This utility model belongs to the field of eyeglasses processing technology, specifically relating to a fixture for eyeglasses. Background Technology

[0002] Common eyeglasses include prescription glasses, hyperopia glasses, astigmatism glasses, and progressive multifocal glasses. They generally consist of temples, frames, and lenses. Frames include semi-rimless, full-rim, rimless, folding, brow-length, and combination frames. Regular lenses have a fixed prescription, requiring the user to choose the appropriate strength; therefore, lenses often have curved surfaces, resulting in more complex frame shapes. Furthermore, the market offers a variety of eyeglass frames with unique and distinctive shapes designed for aesthetics, individuality, and market appeal.

[0003] Currently, when mounting lenses into eyeglass frames, the lenses are typically held manually, and the edges are polished using a grinding machine based on experience to bend, round, or curve them, making gradual corrections step by step. However, this mounting method suffers from low polishing precision, high labor intensity, and long processing time, and further improvements are necessary. Utility Model Content

[0004] The purpose of this invention is to provide a fixture for eyeglasses to solve the problems of low lens polishing accuracy, high labor intensity, and long time consumption in the existing eyeglass clamping process.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

One end of the lens clamp is mounted in the mounting opening, and the other end of the lens clamp has a clamping position for holding a lens. A protective ring protrudes from the mounting opening along its outer edge. A shaping ring is mounted on the fixture table, coaxially positioned around the protective ring. A shaping layer is provided between the shaping ring and the protective ring. A guide block is embedded in the shaping layer, and the embedding path of the guide block follows the shape of the outer edge of the lens template. A slider is slidably connected to the guide block, and a connecting rod connects the slider to the middle of the lens clamp. A driving component is mounted on the fixture table, and the driving component is coupled to the slider to drive the slider to move under the guidance of the guide block.

[0007] In the application, the lens template is a standard reference obtained after the lens is polished; the driving element drives the movement of the sliding block, and the movement of the sliding block is guided under the guidance of the guide splicing block, and the length of the connecting rod is fixed; therefore, during the movement of the sliding block around the lens clamp, the lens clamp is deflected by the connecting rod, and the trajectory of the deflection can be regarded as a virtual trajectory line of the sliding block in the clamping position of the lens clamp, so that the polished lens is finally the same as the lens template, and the same polishing quality and consistency of the product can be obtained by replacing manual polishing, and the efficiency is higher than that of manual polishing.

[0008] Further, a shaping area is arranged between the shaping ring and the protective ring, and a mold wax is arranged in the shaping area to form a shaping layer.

[0009] The mold wax can be heated and cooled, which facilitates the replacement and adjustment of the splicing shape of the guide splicing block, so as to more flexibly adapt to the polishing requirements of lenses of various shapes.

[0010] Further, an electric heating element is arranged on the tooling table, and a heating area of the electric heating element corresponds to the shaping area.

[0011] Further, an inner profiling ring is arranged between the shaping ring and the protective ring, and the shape of the inner profiling ring is profiled on a lens template; and an inner circle of the guide splicing block is attached to an outer surface of the inner profiling ring during splicing. The arranged inner profiling ring can facilitate the shaping of the spliced guide splicing block and ensure the machining precision of the tooling.

[0012] Further, the lens clamp comprises a gas suction nozzle, a ball joint and a ball joint seat, the ball joint is installed on the mounting port through the ball joint seat, and a main rod is connected between the ball joint and the gas suction nozzle.

[0013] Further, the driving element comprises a mounting frame, a driver, a rotating shaft and a magnetic block, the mounting frame is installed on a side of the tooling table away from the lens clamp, the driver is installed on the mounting frame, the rotating shaft is rotatably installed on the mounting frame, one end of the rotating shaft is provided with a connecting plate for fixing the magnetic block, and the other end of the rotating shaft is in transmission connection with the driver.

[0014] Further, the connecting plate is arranged in a circumferential array and has two or more than two; and the end of each connecting plate is fixed with the magnetic block.

[0015] Further, an enclosure is arranged on the outside of the tooling table, a negative pressure dust suction hole is arranged on the inner surface of the enclosure, an air outlet is arranged at the bottom of the enclosure, and the air outlet is connected with a recovery pipeline.

[0016] Through the set cavity, combined with the negative pressure dust hole on it, the dust falling in the polishing process is adsorbed, and the external environment of the tooling can be avoided from being affected by the polishing process.

[0017] The utility model has the advantages that:

[0018] In the application, the sliding block is driven by the driving member to move under the guidance of the guide splicing block; the movement path of the sliding block is the same as the shape of the lens template, and the length of the connecting rod is fixed, so that the lens clamped by the lens clamp can be tilted, and the tilt is adapted to the shape of the lens template, so that the final product after polishing of the lens reaches the precision of the lens template; the automatic polishing mode ensures the quality and consistency of the polishing of the lens edge, has higher precision, improves the processing efficiency, and has high practicability.

DETAILED DESCRIPTION

[0027] The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that similar or identical parts are referred to by the same reference numerals in the drawings or description. Implementations not shown or described in the drawings are forms known to those skilled in the art. Furthermore, directional terms mentioned in the embodiments, such as "up," "down," "top," "bottom," "left," "right," "front," and "back," are only for reference to the directions in the drawings and are not intended to limit the scope of protection of the present invention.

[0028] like Figures 1-5 As shown, an eyeglass clamping fixture according to an embodiment of the present invention includes a fixture table 101 and a lens clamp. The fixture table 101 has a mounting opening in the middle, and one end of the lens clamp is mounted in the mounting opening, which is threaded to facilitate connection with the lens clamp. The other end of the lens clamp has a clamping position for holding a lens 111. A polishing tool for polishing the lens 111 can be mounted on the fixture table 101 to polish the lens 111 in the clamping position. A protective ring protruding from the mounting opening is provided on the outer edge of the mounting opening. A shaping ring 107 is provided on the fixture table 101, coaxially arranged around the protective ring. A shaping layer is provided between the shaping ring 107 and the protective ring, and a guide splicing block 104 is embedded in the shaping layer. The embedding path of the guide splicing block 104 follows the shape of the outer edge of the lens template. When the shaping layer melts, the protective ring can prevent leakage of the shaping layer and thus avoid damage. The guide splicing block 104 is slidably connected to a slider 106. A connecting rod 109 is connected between the slider 106 and the middle of the lens clamp. A connecting ring 110 is rotatably connected to the middle of the lens clamp. The connecting ring 110 is hinged to the connecting rod 109. A driving component is installed on the tooling table 101. The driving component is coupled to the slider 106 to drive the slider 106 to move under the guidance of the guide splicing block 104.

[0029] The driving component includes a mounting bracket 102, a driver 118, a rotating shaft 121, and a magnetic block. The mounting bracket 102 is installed on the side of the tooling table 101 away from the lens fixture. The driver 118 is installed on the mounting bracket 102. The rotating shaft 121 is rotatably mounted on the mounting bracket 102 via bearings. One end of the rotating shaft 121 is equipped with a connecting plate for fixing the magnetic block, and the other end of the rotating shaft 121 is connected to the driver 118 via a gear pair, which includes a driving gear 119 and a driven gear 120. The coupling between the driving component and the slider 106 can be configured as follows: a magnetic block is installed on the slider 106, and the magnetic blocks are arranged opposite each other; the magnetic block serves as the driving magnetic block 122, and the magnetic block serves as the following magnetic block 105, with the driving magnetic block 122 coupled to the following magnetic block 105.

[0030] In the embodiment, the lens template is a standard reference obtained after the lens 111 is polished; the guide splicing block 104 can be spliced in advance according to the lens template, and then the sliding block 106, the connecting rod 109 and the lens clamp are assembled. The driving member works to drive the sliding block 106 to move. The movement of the sliding block 106 is guided by the guide splicing block 104 and moves according to the shape of the lens template. It should be noted that the movement path of the sliding block 106 is the same in shape as the lens template, but the size does not need to be the same and can be appropriately selected according to the actual situation. Therefore, during the movement of the sliding block 106 around the lens clamp, the lens clamp is deflected by the connecting rod 109. The trajectory of the deflection can be regarded as a virtual trajectory line of the sliding block 106 in the clamping position of the lens clamp. In this way, the shape of the polished lens 111 is finally the same as the lens template (or the same as the lens direction of the lens template). The tooling of the embodiment replaces manual polishing of the lens 111, and finally the same polishing quality and consistency of the product can be obtained, and the efficiency is higher than manual polishing, and the practicality is high.

[0031] In the embodiment, the connecting plate is arranged in a circumferential array with four connecting plates; and the end of each connecting plate is fixed with a magnetic block.

[0032] For example, the connecting plate of the embodiment can also be provided with three, five or six connecting plates according to requirements; the magnetic block has strong magnetism and can have magnetic attraction to the ferromagnetic sliding block 106 or the following magnetic block 105 with opposite magnetism. The sliding block 106 and the connecting rod 109 are connected through the hinge joint 108.

[0033] The driving device 118 can be selected from a motor or a pneumatic motor. The output end of the driving device 118 is provided with a driving wheel 119. A driven wheel 120 is arranged at the middle part of the rotating shaft 121. The driven wheel 120 is engaged with the driving wheel 119. The driving device 118 drives the rotating shaft 121 to rotate through the driving wheel 119 and the driven wheel 120. The rotating shaft 121 drives the connecting plate and the magnetic block to rotate. The magnetic block drives the sliding block 106 coupled thereto to rotate. Since the sliding block 106 and the magnetic block are in a coupled relationship but not a hard connection relationship, the movement track of the sliding block 106 can have a small difference or difference from the movement track of the magnetic block. The difference or difference enables the sliding block 106 to move under the guidance of the guide splicing block 104.

[0034] In addition, the size of the magnetic block can be designed to be larger, so that the magnetic field of the magnetic block completely covers the movement of the sliding block 106, realizes the magnetic attraction traction of the sliding block 106, and drives the sliding block 106 to move.

[0035] In one embodiment, the lens clamp comprises an air suction nozzle 112, a ball joint 114 and a ball joint seat 115, the ball joint 114 is installed in the mounting port through the ball joint seat 115, and a main rod 113 is connected between the ball joint 114 and the air suction nozzle 112. The ball joint 114 can be omni-directionally rotated in the ball joint seat 115, so that the main rod 113 is deflected by the connecting rod 109.

[0036] In the middle part of the main rod 113, a connecting groove is arranged, the connecting ring 110 is limited by the connecting groove, and the connecting ring 110 can be rotated relative to the main rod 113; an outer surface of the connecting ring 110 is provided with a connecting hole, and the connecting hole is connected with the hinge hole of the end of the main rod 113.

[0037] For example, the air suction nozzle 112 and the main rod 113 are connected in a plug-in manner, the air suction nozzle 112 is provided with an air inlet and outlet, the air inlet and outlet is connected with an air pump, the lens 111 to be polished is placed on the suction nozzle cap 125 of the air suction nozzle 112, and the suction nozzle cap 125 and the lens 111 form a negative pressure space through air pumping of the air pump, so that the lens 111 is negatively adsorbed.

[0038] For example, the air suction nozzle 112 and the main rod 113 are connected in a threaded connection manner, so that the air suction nozzle 112 can be conveniently installed and replaced, and the practicability is high.

[0039] In the embodiment, a shaping area 116 is arranged between the shaping ring 107 and the protection ring, and a mold wax is arranged in the shaping area 116 to form a shaping layer.

[0040] Exemplarily, the one circle of the guide splicing blocks 104 spliced in the shaping area 116 can be shaped and fixed by making a wax mold; when the guide splicing blocks 104 need to be adjusted, the wax mold is melted; and after the splicing adjustment, the shaping is performed again. In this process, the wax mold used is an important material for making the wax mold. The common wax molds include the following several kinds: paraffin wax: having the characteristics of low melting point, small hardness, easy to melt when heated, good fluidity, etc. In the molten state, it can well fill the mold cavity, and after cooling, it can form a wax mold with a certain shape. However, the wax mold made of pure paraffin wax has relatively low strength and is easy to deform. Bee wax: the melting point of bee wax is slightly higher than that of paraffin wax, and it has good toughness and viscosity. Mixing with paraffin wax can improve the flexibility and strength of the wax mold, so that the wax mold is not easy to break or deform during the making and subsequent processing. Stearic acid: a kind of high-grade saturated fatty acid. In the wax mold, the stearic acid mainly plays the role of plasticizing and lubricating, which can reduce the hardness of the wax mold, increase its flexibility, and at the same time, it can also improve the surface finish of the wax mold, preventing the wax mold from sticking to the mold during the forming process. Polyethylene wax: a kind of polyethylene with low molecular weight, which is polymerized from ethylene monomer under high or low pressure conditions. It has good thermal stability, wear resistance and chemical corrosion resistance. Adding polyethylene wax to the wax mold can improve the strength, hardness and heat resistance of the wax mold, so that it is not easy to soften and deform in a high-temperature environment.

[0041] The guide splicing blocks 104 shaped by the shaping area 116 can be heated and cooled when installed and replaced, which facilitates the replacement and adjustment of the splicing shape of the guide splicing blocks 104, so as to more flexibly adapt to the polishing requirements of various shapes of lenses 111.

[0042] Exemplarily, an inner profiling ring 117 is arranged between the shaping ring 107 and the protection ring, and the shape of the inner profiling ring 117 is profiled to the lens template; the inner circle of the guide splicing block 104 is attached to the outer surface of the inner profiling ring 117 when splicing. The inner profiling ring 117 can facilitate the shaping of the spliced guide splicing blocks 104 and ensure the processing precision of the tooling.

[0043] The shape, size and specification of the inner profiling ring 117 can be prefabricated according to the determined lens template; when the inner profiling ring 117 is installed, the inner profiling ring 117 can be selected according to the specification of the lens 111 to be polished, and the guide splicing blocks 104 are limited by the inner profiling ring 117, and then the spliced guide splicing blocks 104 are shaped by cooling the wax mold.

[0044] In this embodiment, an electric heating element is arranged on the tooling table 101, and the heating area of the electric heating element corresponds to the shaping area 116. For example, the shaping area 116 is formed on the upper surface of the tooling table 101, and the electric heating element can be installed at the corresponding position of the lower surface of the tooling table 101. The wax mold is heated by the electric heating element, so that the wax mold is melted.

[0045] For example, the electric heating element includes a heating plate 124, a power supply and a switch; a support ring 123 is installed on the mounting frame 102, a heat insulation column is installed in the support ring 123, the heating plate 124 is installed on the heat insulation column, and the heating plate 124 is connected to the power supply through the switch; when the switch is closed, the power supply is powered on to the heating plate 124, so that the heating plate 124 generates heat.

[0046] In this embodiment, the outer side of the tooling table 101 is provided with a surrounding cavity, which is an annular shell in the middle of the inside, the inner surface of the surrounding cavity is provided with a negative pressure dust suction hole, the bottom of the surrounding cavity is provided with an air outlet, and the air outlet is connected with a recovery pipeline. In order to facilitate the installation of the tooling table 101, an ear seat 103 is arranged on the outer wall of the surrounding cavity, which is used for the installation and fixation of the tooling table 101 at a specified position.

[0047] The recovery pipeline comprises a recovery pipe and a negative pressure pump connected with the recovery pipe, a filter cavity is arranged on the recovery pipe, and a filter screen is arranged in the filter cavity. Through the surrounding cavity and the negative pressure dust suction hole arranged thereon, the dust falling during polishing can be adsorbed, and the external environment of the tooling during polishing can be avoided.

[0048] The eyeglass clamp tool provided in the embodiment drives the sliding block 106 to move under the guidance of the guide splicing block 104 through the driving piece; the movement path of the sliding block 106 is the same as the shape of the lens template, and the length of the connecting rod 109 is fixed, so that the lens 111 clamped by the lens clamp can be tilted, and the tilt is adapted to the shape of the lens template, so that the final product of the polished lens 111 reaches the precision of the lens template. This automatic polishing method ensures that the polishing quality and consistency of the lens 111 edge are the same, the precision is higher, the processing efficiency is improved, the practicality is high, and the use of the eyeglass clamp tool is more flexible and rich.
