Description

Technical Field

[0001] The utility model relates to the technical field of processing positioning devices, in particular to a processing positioning mechanism and a lens drilling machine. Background Art

[0002] When fitting rimless glasses, the polished lenses are transparent and colorless, and there are no specific coordinates on the lenses. Traditional punching machines rely on manual drilling, which makes it difficult to accurately position and symmetrically position the holes when assembling rimless glasses. If there is even a small error in the hole position between the two lenses, the assembled glasses will be crooked, making them look very unsightly when worn. Generally, demanding customers will ask the optician to re-fit the lenses or even return the products, which causes great losses to the store (because some lenses are very expensive, such as German Zeiss lenses).

[0033] Example 1

[0034] In order to solve the problems of processing accuracy and efficiency during material processing (using drilling processing as an example), the embodiment of the present application discloses a processing positioning structure and a lens drilling machine to improve the processing accuracy and efficiency during the processing process; the processing positioning structure can be an auxiliary device for drilling, polishing, cutting, etc. For ease of understanding, drilling is used as an example below.

[0035] Please refer to the attached Figure 1-4 The first aspect of the embodiment of the present application discloses a processing positioning mechanism, comprising a base 100; a positioning platform 200, slidably connected to the base 100 and used to position a workpiece to be processed; at least two sets of stroke limiting components 300, connected to the base 100, and respectively limiting the sliding stroke of the positioning platform 200 in opposite sliding directions of the positioning platform 200, and the distance between the stroke limiting component 300 and the positioning platform 200 is adjustable; Figure 3 As shown, the travel limiting assemblies 300 are provided in two groups.

[0036] In the above embodiment, the designated workpiece to be processed is positioned by the positioning platform 200, and the positioning platform 200 is controlled to slide to abut against one set of stroke limiting components 300 to process the workpiece to be processed at the first position; after the first position of the workpiece to be processed is processed, the positioning platform 200 is controlled to slide in the opposite direction to abut against another set of stroke limiting components 300, and then the workpiece to be processed is processed at the second position; and the distance between the stroke limiting component 300 and the positioning platform 200 is adjustable, so the user can preset the processing position on the workpiece to be processed according to his own needs; and after processing the first position, it can be quickly and accurately switched to the second processing position by simple sliding, which helps to improve processing accuracy and improve processing efficiency; for ease of understanding, for example, you can refer to Figure 3 , the positioning platform 200 moves to the left, driving the abutment portion 330 located on the front side of the positioning platform 200 to abut against the limiting piece 320 on the front side of the positioning platform 200; this is the first processing position; after processing, the positioning platform 200 moves to the right, and the abutment portion 330 on the right side of the positioning platform 200 abuts against the limiting piece 320 on the right side of the positioning platform 200, which is the second processing position.

[0037] In some embodiments of the present application, a connecting positioning structure (not shown) is provided between the stroke limiting component 300 and the positioning platform 200, so that when the positioning platform 200 abuts against the stroke limiting component 300 and needs to be processed, the connecting positioning structure fixes the position between the positioning platform 200 and the stroke limiting component 300 to prevent the positioning platform 200 from moving when subjected to force during processing.

[0038] Furthermore, the connection and positioning structure can be selected as a quick-install and quick-disassemble structure, which can facilitate the quick connection and quick disassembly between the positioning platform 200 and the stroke limiting component 300; for example, the connection and positioning structure includes a first magnetic block and a second magnetic block, and the first magnetic block and the second magnetic block are respectively connected to the positioning platform 200 and the stroke limiting component 300; for example, the connection and positioning structure includes a slot and a protrusion, and the protrusion and the slot are interference fit, and the protrusion and the slot are respectively connected to the positioning platform 200 and the stroke limiting component 300, and the quick connection and quick separation between the positioning platform 200 and the stroke limiting component 300 are achieved by quick plugging and unplugging between the protrusion and the slot, and the positioning platform 200 can be effectively prevented from being force-displaced during processing.

[0039] In some embodiments of the present application, the stroke limiting assembly 300 includes a connecting bracket 310, a limiting member 320 and an abutment portion 330, and the base 100 is connected to the limiting member 320 through the connecting bracket 310; the abutment portion 330 is arranged on one side of the positioning platform 200 and is opposite to the limiting member 320, and the distance between the limiting member 320 and the abutment portion 330 is adjustable.

[0040] In the above embodiment, the limit member 320 is connected to the base 100 through the connecting bracket 310, and the abutment portion 330 is connected to the positioning platform 200 and is also arranged opposite to the limit member 320; when the positioning platform 200 moves, it drives the abutment portion 330 to approach or move away from the limit member 320. When the positioning platform 200 drives the abutment portion 330 to abut against the limit member 320, it is a processing position at this time, and the workpiece to be processed can be processed by drilling equipment, grinding equipment, etc.; and the distance between the limit member 320 and the abutment portion 330 is adjustable, so before processing, the user can preset the distance between the two according to the actual processing needs of the workpiece to be processed (here the workpiece to be processed has two or more processing positions). After preset, it can quickly switch between different processing positions of the workpiece to be processed.

[0041] In some embodiments of the present application, Figure 3 As shown, the limiter 320 is configured as a caliper and at least the measuring end of the caliper can move closer to or farther from the abutment 330 in the horizontal direction. That is, when the caliper is a measuring tool such as a vernier caliper that can retract the measuring end by rotation, the user can directly and accurately control the distance between the abutment 330 and the limiter 320 through the caliper reading. If the caliper is a measuring tool whose measuring end cannot retract, the caliper itself and the measuring end can be configured to move as a whole to control the distance between the abutment 330 and the limiter 320, and the reading can be read in real time. It is convenient to set the preset distance; in another embodiment, the limit member 320 is configured as a bolt, which is threadedly connected to the connecting bracket 310, and the bolt moves in the horizontal direction close to or away from the abutment portion 330; it should be understood that since the present case has at least two sets of travel limit assemblies 300, it represents that there are multiple limit members 320, and the multiple limit members 320 can all be configured as calipers, or can all be configured as bolts, or some of the limit members 320 can be calipers and some of the limit members 320 can be bolts; Figure 3 As shown, a first set of stroke limiting components 300 (caliper type) is provided on the side, and a second set of stroke limiting components 300 (bolt type) is provided in the sliding direction of the positioning platform 200 .

[0042] In some embodiments of the present application, the stroke limiting assembly 300 is arranged on one side of the sliding direction of the positioning platform 200, and the abutment portion 330 extends from one side of the positioning platform 200 and is arranged opposite to the limiting member 320; it can reduce the overall length of the entire structure and facilitate miniaturization.

[0043] In some embodiments of the present application, the stroke limiting component 300 can also be set in the sliding direction of the positioning platform 200 to directly limit the positioning platform 200; since there are multiple stroke limiting components 300, it can be understood that, for example Figure 3As shown, a portion of the stroke limiting assembly 300 is disposed on one side of the sliding direction of the positioning platform 200 , and another portion of the stroke limiting assembly 300 is disposed in the sliding direction of the positioning platform 200 .

[0044] In some embodiments of the present application, the positioning platform 200 is arranged on the base 100, and the positioning platform 200 and the base 100 are connected by a sliding connection structure 600; the sliding connection structure 600 includes a fixed plate 610 and a slider 620, and a horizontal sliding groove is provided in the fixed plate 610, and the slider 620 can slide in the horizontal sliding groove; one side of the base 100 is connected to one of the fixed plate 610 and the slider 620; the positioning platform 200 is connected to the other one of the fixed plate 610 and the slider 620; the sliding connection structure 600 can also be other structural designs, which are not limited here.

[0045] In some embodiments of the present application, the processing positioning mechanism further includes a mounting frame 400, the base 100 is rotatably connected to the mounting frame 400, and the angle between the base 100 and the horizontal plane is adjustable; in this way, the inclination angle of the positioning platform 200 on the base 100 can be adjusted. When processing curved products such as eyeglass lenses or lenses of different thicknesses, the inclination angle of the positioning platform 200 can be adjusted to achieve vertical processing between the drill bit and the lens, thereby facilitating drilling; at the same time, it can also complete some other required inclined hole processing; optionally, such as Figure 4 As shown, the mounting bracket 400 includes two relatively arranged rotating seats 410, and the same rotating shaft 420 is passed through and rotatably arranged between the two rotating seats 410. The rotating shaft 420 is fastened by an arc buckle 430, and the arc buckle 430 and the rotating shaft 420 are locked on the base 100 by screws, so that the base 100 can drive the rotating shaft 420 to rotate around the axis of the two rotating seats 410.

[0046] In some embodiments of the present application, the first end of the base 100 is rotatably connected to the mounting frame 400, and the second end of the base 100 is connected to a height adjustment mechanism 500, which is used to adjust the height of the second end of the base 100; when in use, the second end of the base 100 is raised or lowered by the height adjustment mechanism 500, while the first end of the base 100 is rotatably connected and its height does not change, so the inclination angle of the base 100 and the positioning platform 200 will also change accordingly.

[0047] In some embodiments of the present application, the height adjustment mechanism 500 includes a ruler 510, which is vertically arranged and at least the measuring end of the ruler 510 can be moved in a vertical plane and locked in position; through the setting of the ruler 510, the height reading can be observed in real time, thereby accurately controlling the inclination angle of the positioning platform 200 to facilitate the completion of the processing requirements of the hole to be processed.

[0048] In some embodiments of the present application, the ruler 510 is a vernier caliper or micrometer with a retractable measuring head. The extension and retraction of the measuring head is controlled by screwing the ruler 510, thereby controlling the height of the base 100; and when the action of screwing the ruler 510 stops, the measuring end of the ruler 510 is automatically locked, making the operation more convenient.

[0049] In some embodiments of the present application, a positioning member 210 protruding from the positioning platform 200 is provided on the positioning platform 200, and a centering line 220 used in conjunction with the positioning member 210 is also provided on the positioning platform 200; the positioning member 210 is used as a support for the workpiece to be processed, and the centering line 220 is used as a reference line; for example, when processing the lens, the position where the hole needs to be punched on the lens is determined. Generally speaking, the installation of frameless glasses requires two or four holes on the same straight line. Therefore, a line is first drawn at the position where the hole needs to be punched on the lens to connect multiple holes, and then one side of the lens is abutted against the positioning member 210, and the drawn line on the lens is aligned with the centering line 220, and the positioning platform 200 is moved to abut against one set of stroke limiting components 300 to punch the first hole; then the positioning platform 200 is moved in the opposite direction to abut against the other set of stroke limiting components 300 to punch the second hole, making the entire operation process simple, accurate and fast.

[0050] The second aspect of the embodiment of the present application discloses a lens drilling machine, which is characterized in that it includes the above-mentioned processing positioning mechanism and a bench drill 700, and the bench drill 700 is installed on one side of the processing positioning mechanism, and the eyeglass lens positioned on the processing positioning mechanism is drilled by the bench drill 700.
