Description

Technical Field

[0001] The utility model relates to the field of fixtures, and more specifically to a tooling fixture for detecting the strength of optical glass. Background Art

[0002] Optical glass is a special glass material with excellent optical properties and is widely used in the optical field. However, when the optical glass is clamped in the existing tooling fixture and the strength test is performed on the refractometer, it is impossible to quickly clamp, install and test the optical glass. Therefore, it is necessary to improve the tooling fixture used to clamp the optical glass.

[0003] The document with the prior art announcement number CN221224417U provides a tooling fixture for optical glass strength testing. This technical solution drives the buffer cylinder, buffer rod, mounting block, clamp and spring washer to move during the closing process of the observation window, so that two groups of spring washers can synchronously clamp the optical glass. When the slide drives the buffer cylinder to continue to move in the direction close to the clamp, the buffer rod stretches the first spring and squeezes the hydraulic oil in the buffer cylinder to transport it into the working cylinder. At this time, under the action of the buffer rod, the clamping force of the clamp and spring washer on the optical glass driven by the buffer cylinder is neutralized, so that the clamping force of the two groups of spring washers on the optical glass is moderate, avoiding the buffer cylinder driving the clamp and spring washer to excessively clamp the optical glass, and improving the safety of the tooling fixture in clamping the optical glass.

[0004] Although the device has many beneficial effects, the following problems still exist: when the buffer mechanism is driven by the opening and closing of the observation window to clamp the optical glass sample, the top of the placed optical glass has no infinite position structure, which can easily cause the side of the optical glass to tilt when squeezed, which is not conducive to the use of optical glass detection.

[0005] In view of this, we propose an optical glass strength testing fixture. Utility Model Content

[0025] 3. Beneficial effects

[0026] Compared with the prior art, the beneficial effects of the utility model are:

[0027] 1. The present application utilizes the optical glass to be inserted between two clamps and when it is in rolling friction contact with the arc roller plate, the arc roller plate squeezed by the optical glass pushes the pressing roller plate to move up, thereby increasing the pressing gap between the pressing roller plate and the lifting roller plate, so that the optical glass can be placed more flat, and the lifting roller plate squeezed by the optical glass pulls the elastic stretching member to elastically stretch, thereby increasing the clamping distance between the two symmetrically arranged lifting roller plates, so that the device can clamp and fix optical glasses of different specifications and sizes, thereby improving the flexibility of the device for optical glass clamping detection, and the rollers that are rotatably connected to the roller pressure plate, the lifting roller plate, the pressing roller plate and the arc roller plate are all made of rubber material, so that they can meet the rolling transmission of the optical glass, reduce friction resistance, and ensure the stability of the placement of the optical glass.

[0028] 2. In the present application, when the optical glass is inserted between two clamps for fixing, the optical glass squeezes the arc-shaped seesaw, thereby pushing the pressure plate to limit and elastically flip. At this time, the elastically flipped pressure plate drives the externally rotating rod frame to limit and lift, so that the lifted rod frame drives the guide plate that is slidably connected and hingedly installed in the slot plate to limit and flip to form an inclined surface, thereby effectively discharging the debris that has fallen into the slot plate, sliding it into the debris box for collection, and keeping the slot plate clean. The hinged installation of the guide plate can discharge the fallen debris through effective actions, thereby enhancing the discharge effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0038] See also Figure 1-4 ,The utility model provides a technical solution:

[0039] An optical glass strength testing fixture, comprising: a strength tester body 1, a slot plate 2, a guide rod frame 3, a roller pressing plate 4, an elastic stretching member 5 and a fixture member 6;

[0040] The slot plate 2 is fixedly installed in the mounting slot inside the strength detector body 1;

[0041] The guide rod frame 3 is fixedly mounted in the middle of the slot plate 2 and is slidably limited with the clamp member 6;

[0042] The roller pressure plate 4 is fixedly mounted on one side of the guide rod frame 3;

[0043] The elastic stretching member 5 is installed in the guide rod frame 3 and is hingedly installed with the clamp member 6;

[0044] There are two clamping parts 6, which are respectively arranged on both sides of the guide rod frame 3. The clamping parts 6 include a slide rail plate 61, a lifting roller plate 62, a pressure rod 63, a pressing roller plate 64 and an arc roller plate 65.

[0045] The slide rail plate 61 is slidably connected to the outside of the guide rod frame 3 and is hingedly installed with the elastic stretching member 5;

[0046] The pressure rod 63 is fixedly mounted on one side of the pressing roller plate 64 and is slidably connected to the lifting roller plate 62. An elastic element is sleeved on the outer side of the pressure rod 63. The pressing roller plate 64 and the lifting roller plate 62 are elastically connected through the elastic element. The lifting roller plate 62 is fixedly mounted on one side of the slide rail plate 61.

[0047] The arc roller plates 65 are fixedly mounted on one side of the pressing roller plate 64 and the lifting roller plate 62 respectively;

[0048] The rollers rotatably connected in the roller pressing plate 4, the lifting roller plate 62, the pressing roller plate 64 and the arc roller plate 65 are all made of rubber.

[0049] This technical solution utilizes the optical glass to be inserted between the two clamps 6 and to be in rolling friction contact with the arc roller plate 65. The arc roller plate 65 squeezed by the optical glass pushes the pressing roller plate 64 to move upward, thereby increasing the pressing gap between the pressing roller plate 64 and the lifting roller plate 62, so that the optical glass can be placed more flat. The lifting roller plate 62 squeezed by the optical glass pulls the elastic stretching member 5 to elastically stretch, thereby increasing the clamping distance between the two symmetrically arranged lifting roller plates 62, so that the device can clamp and fix optical glasses of different specifications and sizes, thereby improving the flexibility of the device for optical glass clamping detection. The rollers rotatably connected in the roller pressure plate 4, the lifting roller plate 62, the pressing roller plate 64 and the arc roller plate 65 are all made of rubber material, so that they can meet the rolling transmission of the optical glass, reduce friction resistance, and ensure the stability of the placement of the optical glass.

[0050] Reference Figure 5 and Figure 6 The slot plate 2 is arranged in a grid-like structure, and a debris box 21 is fixedly connected to one side of the slot plate 2 arranged in a grid-like structure, and a material guide plate 22 is hingedly installed inside the slot plate 2, and a rod frame 43 is slidably connected in a limit frame installed on the side wall of the material guide plate 22, and a pressing plate 41 is rotatably connected to the outside of the rod frame 43, and one end of the pressing plate 41 arranged in a right-angle structure is fixedly connected to an arc-shaped rocker plate 42, and the pressing plate 41 is elastically hingedly installed on one side of the roller pressure plate 4 through a torsion spring.

[0051] This technical solution utilizes the optical glass inserted between the two clamps 6 for fixing. The optical glass squeezes the arc-shaped seesaw 42, thereby pushing the pressing plate 41 to elastically flip over. At this time, the elastically flipped pressing plate 41 drives the externally rotatably connected rod frame 43 to limit and lift, so that the lifted rod frame 43 drives the guide plate 22 slidably connected and hingedly installed in the slot plate 2 to limit and flip over to form an inclined surface, thereby effectively discharging the debris that has fallen into the slot plate 2, sliding it into the debris box 21 for collection, and keeping the slot plate 2 clean. The hinged installation of the guide plate 22 can discharge the fallen debris through effective actions.

[0052] Reference Figure 7 and Figure 2 , the elastic stretching member 5 includes a positioning shaft 51, a sliding sleeve seat 52 and a push-pull rod 53;

[0053] The positioning shaft 51 with the spring member is fixedly installed in the guide rod frame 3 and slidably cooperates with the sliding sleeve seat 52;

[0054] There are two push-pull rods 53 , which are hingedly mounted on the outside of the sliding sleeve seat 52 in a symmetrical structure, and the other end of each push-pull rod 53 is hingedly mounted on one side of the sliding rail plate 61 .

[0055] This technical solution utilizes that when the optical glass is inserted between two clamp members 6 for fixing, the clamp member 6 that is squeezed and expanded outward by the optical glass pulls the hinged push-pull rod 53 to limit the extension. At this time, the extended push-pull rod 53 drives the sliding sleeve seat 52 that is hingedly installed at the other end to limit the position outside the positioning shaft 51 of the sleeve spring member to squeeze the spring member to displace, and elastically holds the clamp member 6 that is squeezed and expanded outward by the optical glass, thereby ensuring that the clamp member 6 can clamp and fix optical glasses of different specifications and sizes.
