Description

Technical Field

[0001] This utility model belongs to the field of iron frame mirror inlay technology, specifically relating to a positioning fixture for iron frame mirror inlay. Background Technology

[0002] Framed mirrors typically refer to mirrors where lenses are embedded in a metal frame, commonly found in eyeglasses, decorative mirrors, or mirrors for special purposes. This process involves meticulous craftsmanship and precise operation to ensure the lens is securely set in the frame, achieving both practicality and aesthetics. To prevent the frame from shifting under external forces during the frame-setting process, positioning fixtures are used to ensure stability.

[0003] Existing positioning fixtures for framed mirrors are usually quite fixed and not flexible enough, especially when positioning and processing items of different sizes or sizes. They are not as flexible as some more adjustable or modular fixtures, which reduces their adaptability. Furthermore, because fixed and non-adjustable positioning fixtures lack flexibility, more time is needed to change and adjust to suitable positioning fixtures, which reduces production efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a positioning fixture for setting mirrors in iron frames. It can be adjusted according to the size of different frames, adapting to the processing of frames of various specifications. This avoids the problem of frequently changing fixtures when using fixed fixtures, and improves the flexibility and continuity of production.

[0005] The specific technical solution adopted by this utility model is as follows:

[0006] A positioning fixture for setting mirrors in iron frames includes a processing table, the interior of which is a cavity, and a positioning mechanism is provided inside the processing table.

[0007] The positioning mechanism includes: a base plate, which is disposed inside the processing table;

[0008] A fixing block, which is fixedly installed on the top of the base plate;

[0009] Ear plate, one end of which is connected to both sides of the fixing block via a rotating shaft;

[0010] A positioning element, which is connected to the other end of the ear plate via a pivot and is located on the inner side of the ear plate;

[0011] An electric telescopic rod is fixedly installed at the bottom of the base plate, and the top end of the electric telescopic rod extends through to the top of the base plate;

[0012] A connecting frame is fixedly installed at the top of the electric telescopic rod, and the connecting frame is connected to the end of the positioning component via a rotating shaft;

[0013] An adjustment mechanism is provided at the bottom of the positioning mechanism.

[0014] Preferably, the adjusting mechanism includes a bidirectional lead screw, a guide rod, and connecting blocks. One end of the bidirectional lead screw is connected to the rear side of the inner wall of the processing table via a bearing, and the other end of the bidirectional lead screw extends to the front side of the processing table. The guide rod is fixedly connected to the inner wall of the processing table and is located on both sides of the bidirectional lead screw. Both connecting blocks are threaded to the surface of the bidirectional lead screw and slidably connected to the surface of the guide rod. The two connecting blocks are respectively fixedly connected to the top of the electric telescopic rod.

[0015] Preferably, a knob is fixedly connected to the end of the bidirectional lead screw, and the knob is circular in shape.

[0016] Preferably, sliding blocks are fixedly connected to both sides of the base plate, and sliding rods are fixedly connected to the inner wall of the processing table and located on both sides of the base plate, with the sliding blocks slidably connected to the surface of the sliding rods respectively.

[0017] Preferably, the top of the processing table has two vertical grooves, and the positioning element is slidably connected to the inside of the two vertical grooves respectively.

[0018] Preferably, a pressing member is fixedly connected to the bottom of the positioning member, and the pressing member is square.

[0019] The technical effects achieved by this utility model are as follows:

[0020] In this invention, when processing a mirror frame inlay and positioning the frame, the frame can be placed under two positioning components on the processing table. Then, two electric telescopic rods are operated simultaneously. The operation of the electric telescopic rods pushes the connecting frame upwards, which in turn pushes one end of each positioning component upwards. With the support of the ear plate, the other end of each positioning component is pressed downwards. When both ends of the positioning components are pressed downwards simultaneously, the frame is pressed down and limited on the processing table. When positioning and fixing frame frames of different sizes, the double-ended lead screw can be rotated clockwise using a knob. The rotation of the double-ended lead screw drives the two threaded connecting blocks to move outwards simultaneously under the auxiliary guidance of the guide rod. Lateral movement: When the two connecting blocks move outward simultaneously, the top electric telescopic rod and the positioning mechanism move in opposite directions, increasing the distance between the two positioning parts. When positioning small iron frames for mirror inlay, the double-sided lead screw can be rotated counterclockwise to move the two positioning mechanisms relative to each other, thus reducing the distance between the two positioning parts and providing auxiliary positioning for small iron frames. Through the cooperation of the adjustment mechanism and the positioning mechanism, adjustments can be made according to the size of different iron frames, adapting to the processing of various specifications of iron frames. This avoids the problem of frequent tooling changes required when using fixed tooling, improving the flexibility and continuity of production. Attached Figure Description

[0026] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0027] like Figures 1-3As shown, a positioning fixture for setting mirrors in iron frames includes a processing table 1, the interior of which is hollow, and a positioning mechanism is provided inside the processing table 1. The positioning mechanism includes: a base plate 201, which is disposed inside the processing table 1; a fixing block 202, which is fixedly installed on the top of the base plate 201; an ear plate 203, one end of which is connected to both sides of the fixing block 202 via a pivot; a positioning element 204, which is connected to the other end of the ear plate 203 via a pivot and is located inside the ear plate 203; an electric telescopic rod 205, which is fixedly installed on the bottom of the base plate 201, and the top end of the electric telescopic rod 205 extends through to the top of the base plate 201; a connecting frame 206, which is fixedly installed on the top end of the electric telescopic rod 205 and is connected to the end of the positioning element 204 via a pivot; and an adjustment mechanism, which is disposed within the positioning mechanism. At the bottom, the adjustment mechanism includes a bidirectional lead screw 301, a guide rod 302, and connecting blocks 303. One end of the bidirectional lead screw 301 is connected to the rear side of the inner wall of the processing table 1 via a bearing, and the other end of the bidirectional lead screw 301 extends to the front side of the processing table 1. The guide rod 302 is fixedly connected to the inner wall of the processing table 1 and is located on both sides of the bidirectional lead screw 301. Both connecting blocks 303 are threaded to the surface of the bidirectional lead screw 301 and slidably connected to the surface of the guide rod 302. The two connecting blocks 303 are respectively fixedly connected to the top of the electric telescopic rod 205. Through the cooperation of the positioning mechanism and the adjustment mechanism, the distance between the two positioning parts 204 of the positioning mechanism can be flexibly adjusted. The adjustable positioning fixture can adapt to different sizes of frames, improving the versatility of the fixture. The same set of fixtures can be used for a variety of different products, reducing the number of times and time to change fixtures, and significantly improving the processing efficiency of setting mirrors in iron frames.

[0028] like Figures 1-2 As shown, a knob 304 is fixedly connected to the end of the bidirectional lead screw 301. The knob 304 is circular in shape. When adjusting the positioning mechanism, the bidirectional lead screw 301 can be adjusted manually by the operator without the need for additional complicated tools. Fine adjustment can be achieved by rotating the knob 304, and the bidirectional lead screw 301 can be adjusted in small steps as needed.

[0029] like Figures 2-3 As shown, sliding blocks 401 are fixedly connected to both sides of the base plate 201, and sliding rods 402 are fixedly connected to the inner wall of the processing table 1 and located on both sides of the base plate 201. The sliding blocks 401 are slidably connected to the surface of the sliding rods 402 respectively. When the positioning mechanism is moved, the base plate 201 can drive the sliding blocks 401 to slide on the surface of the sliding rods 402. With the cooperation of the sliding blocks 401 and the sliding rods 402, the base plate 201 and the positioning mechanism can be limited and assisted to move smoothly, preventing the positioning mechanism from shaking or deviating due to lack of limiting assistance when moving.

[0030] like Figure 1 As shown, the top of the processing table 1 has two vertical grooves 5. The positioning component 204 is slidably connected to the inside of the two vertical grooves 5 respectively. When the positioning mechanism moves, the positioning component 204 will slide flexibly inside the vertical grooves 5 to avoid the positioning component 204 from colliding with the processing table 1 and causing motion interference.

[0031] like Figures 1-3 As shown, a pressing member 6 is fixedly connected to the bottom of the positioning member 204. The pressing member 6 is square. When the positioning member 204 presses down on the iron frame for positioning, the positioning member 204 will drive the rubber pressing member 6 to press down and fix the iron frame. The rubber pressing member 6 can increase the friction when it contacts the surface of the iron frame, preventing the iron frame from sliding or moving when subjected to external force. The softness of the rubber allows it to better fit the uneven surface and provide a stronger fixing effect. At the same time, the rubber material is soft and will not easily scratch or damage the iron frame or other surfaces like metal, thus protecting the processed iron frame.

[0032] The working principle of this utility model is as follows: When processing a mirror frame inlay and positioning the iron frame is required, the iron frame can be placed under the two positioning parts 204 on the processing table 1. Then, the two electric telescopic rods 205 are operated simultaneously. The operation of the electric telescopic rods 205 will push the connecting frame 206 upward. The upward movement of the connecting frame 206 can simultaneously push one end of the positioning part 204 upward, and under the connection and support of the ear plate 203, the other end of the positioning part 204 is pressed downward. When the ends of the two positioning parts 204 are pressed downward at the same time, the iron frame can be pressed down and limited on the processing table 1. When positioning and fixing iron frames of different sizes, the double-acting screw 301 can be rotated clockwise by the knob 304. The rotation of the double-acting screw 301 can drive the two threaded connecting blocks 30 3. Under the auxiliary guidance of the guide rod 302, both connecting blocks 303 move outward simultaneously. When both connecting blocks 303 move outward simultaneously, the top electric telescopic rod 205 and the positioning mechanism move in opposite directions, increasing the distance between the two positioning parts 204. When positioning a small iron frame for mirror inlay, the double-acting screw 301 can be rotated counterclockwise to move the two positioning mechanisms relative to each other, thereby reducing the distance between the two positioning parts 204 and assisting in positioning the small iron frame. Thus, through the cooperation of the adjustment mechanism and the positioning mechanism, adjustments can be made according to the size of different iron frames, adapting to the processing of iron frames of various specifications. This avoids the problem of frequently changing tooling when using fixed tooling, improving the flexibility and continuity of production.

[0033] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
