Description

Technical Field

[0001] This application relates to the field of polishing stand technology, specifically to a lens polishing stand with adjustable angle. Background Technology

[0002] In the manufacturing process of optical lenses and spectacle lenses, grinding (or polishing) is a crucial finishing step. Its purpose is to eliminate fine scratches on the lens surface, improve surface accuracy, and achieve the required optical performance. A search revealed a utility model patent with publication number CN111604757A, which discloses a grinding fixture for lens processing. This fixture includes a cup-shaped support body with an annular rubber support ring on its upper surface, a flexible sealing ring on the upper surface of the annular rubber support ring, a pressure relief valve on one side of the cup-shaped support body, an air distribution block inside the cup-shaped support body, a connecting body connected to the bottom of the cup-shaped support body, a fixed base on the outer side of the connecting body, an air extraction pipe connected to the bottom of the connecting body, and a blower connected to the other end of the air extraction pipe.

[0003] However, during polishing, the lens often needs to be tilted at a specific angle so that the polishing tool can better match the curved surface of the lens to achieve uniform and efficient polishing. Traditional lens fixing stands are mostly horizontally fixed, with a limited angle adjustment range. In addition, some simple threaded adjustment mechanisms lack effective self-locking functions, which can easily loosen and shift, causing the polishing angle to deviate and affecting product quality. Utility Model Content

[0004] The purpose of this invention is to provide a lens grinding stand with adjustable angle, which solves the problems of limited adjustment range and easy loosening of traditional lens fixing stands.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a lens grinding stand with adjustable angle, comprising a base, an adjusting seat fixedly connected to the upper middle part of the base, a hinged seat hinged to the left side of the adjusting seat, a tooling plate fixedly connected to the top of the hinged seat, a threaded shaft mounted inside the adjusting seat via a bearing, the threaded shaft penetrating the adjusting seat, a movable seat threadedly connected to the outer side of the threaded shaft via a thread, the movable seat slidably connected to the inner side of the adjusting seat, a connecting arm hinged to the top of the movable seat, the other end of the connecting arm hinged to the bottom of the tooling plate, and an adjusting locking mechanism jointly provided between the threaded shaft and the adjusting seat.

[0006] Preferably, the tooling tray has an internal cavity, a positioning groove in the upper center, and several through holes at the bottom of the positioning groove that communicate with the cavity. A connecting pipe is fixedly connected to the right side of the tooling tray, and the connecting pipe also communicates with the cavity. By connecting the connecting pipe to the exhaust / exhaust mechanism, the lens can be fixed in the positioning groove using a suction method.

[0007] Preferably, a rotating wheel, made of stainless steel, is welded to one end of the threaded shaft outside the adjusting seat. The rotating wheel facilitates the rotation of the threaded shaft.

[0008] Preferably, the adjusting locking mechanism includes a locking disc fixedly connected to the threaded shaft body. A hollow shell is fixedly connected to the inner side of the adjusting seat. An inclined block is slidably connected inside the hollow shell. A locking pin is fixedly connected to the inclined block. The locking pin passes through the hollow shell and is slidably connected to it. The locking pin is inserted into the locking disc. A push rod is slidably connected to the top of the hollow shell. The push rod passes through the hollow shell. The lower end of the push rod contacts the inclined surface of the inclined block. A pressing block is fixedly connected to the upper end of the push rod. By adjusting the locking mechanism, the threaded shaft is locked and prevented from loosening after adjustment.

[0009] Preferably, the lock disc has multiple insertion holes inside, and these holes are arranged in a circular array along the circumference of the lock disc. The locking pin is inserted into these insertion holes. The insertion holes facilitate the insertion of the locking pin after the lock disc rotates with the threaded shaft.

[0010] Preferably, a guide rod is fixedly connected to the inner wall of the hollow shell, and the guide rod is slidably connected to the inclined block. A spring is installed inside the inclined block, one end of which is fixedly connected to the guide rod, and the other end of which is fixedly connected to the inner surface of the inclined block. The guide rod and spring provide auxiliary repositioning for the inclined block.

[0011] Preferably, a corrugated sleeve is fixedly connected to the bottom of the pressing block, and the bottom of the corrugated sleeve is fixedly connected to the upper end of the hollow shell. The corrugated sleeve prevents the pressing block and push rod from falling off.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model achieves precise adjustment of the lens clamping angle through the linkage design of the threaded shaft, the moving seat, and the connecting arm, combined with the hinge structure at the bottom of the tooling tray. At the same time, combined with the vacuum adsorption fixing method, it effectively avoids lens displacement or vibration during the grinding process, thus improving the stability of lens processing.

[0014] 2. This utility model provides an adjustment and locking mechanism at the threaded shaft used for adjustment.

A connecting pipe 44 is fixedly connected to the right side of the tooling tray 4, and the connecting pipe 44 communicates with the cavity 41. By connecting the connecting pipe 44 to a suction / exhaust mechanism, the lens can be fixed by suction when placed in the positioning groove 42.

[0022] Please see Figures 1-3Inside the adjusting seat 2, a threaded shaft 5 is mounted via bearings, and the threaded shaft 5 penetrates the adjusting seat 2. A movable seat 6 is threadedly connected to the outer side of the threaded shaft 5, and the movable seat 6 is slidably connected to the inner side of the adjusting seat 2. A connecting arm 7 is hinged to the top of the movable seat 6, and the other end of the connecting arm 7 is hinged to the bottom of the tooling plate 4. A rotating wheel 8, made of stainless steel, is welded to one end of the threaded shaft 5 located outside the adjusting seat 2. The rotating wheel 8 facilitates the rotation of the threaded shaft 5.

[0023] Please see Figures 3-4 An adjusting locking mechanism 9 is provided between the threaded shaft 5 and the adjusting seat 2. This mechanism locks the threaded shaft 5 after adjustment, preventing loosening. The adjusting locking mechanism 9 includes a locking disc 91 fixedly connected to the shaft body of the threaded shaft 5. A hollow shell 92 is fixedly connected to the inner side of the adjusting seat 2. An inclined block 93 is slidably connected inside the hollow shell 92. A locking pin 94 is fixedly connected to the inclined block 93, penetrating and slidably connected to it. The locking pin 94 is inserted into the locking disc 91. A push rod 97 is slidably connected to the top of the hollow shell 92, penetrating it. The lower end of the push rod 97 contacts the inclined surface of the inclined block 93, and a pressing block 98 is fixedly connected to the upper end of the push rod 97. The locking disc 91 has multiple insertion holes arranged in a circular array along its circumference. The locking pin 94 is inserted into these holes. The insertion hole facilitates the insertion of the locking pin 94 after the locking disc 91 rotates with the threaded shaft 5. A guide rod 95 is fixedly connected to the inner wall of the hollow shell 92, and the guide rod 95 is slidably connected to the inclined block 93. A spring 96 is installed inside the inclined block 93, with one end fixedly connected to the guide rod 95 and the other end fixedly connected to the inner surface of the inclined block 93.

The corrugated sleeve 99 prevents the pressing block 98 and the push rod 97 from falling off.

[0024] The specific implementation process of this utility model is as follows: First, the lens to be polished is placed in the positioning groove 42 at the upper end of the tooling tray 4. Then, the external vacuum equipment is connected to the connecting pipe 44 on the right side of the tooling tray 4 through a hose and started. The negative pressure is transmitted to the cavity 41 through the connecting pipe 44, and then acts on the bottom of the lens through several through holes 43. The atmospheric pressure is used to firmly and evenly adsorb the lens into the positioning groove 42, completing the clamping. If it is necessary to adjust the angle of the tooling tray 4, the operator only needs to rotate the threaded shaft 5 through the rotating wheel 8. The rotation of the threaded shaft 5 will drive the moving seat 6, which is threaded with it, to slide back and forth along the inner side of the adjusting seat 2. The moving seat 6... The hinged connecting arm 7 pushes and pulls the bottom of the tooling plate 4. Then, under the pushing and pulling action of the connecting arm 7, the tooling plate 4 will be raised or lowered around the hinge point, thereby achieving angle adjustment until the desired ideal grinding angle is reached. In addition, before the threaded shaft 5 rotates, the push rod 97 needs to be pushed down by the pressing block 98. The lower end of the push rod 97 presses the inclined surface of the inclined block 93, so that the inclined block 93 overcomes the elastic force of the spring 96 and slides backward along the guide rod 95, thereby removing the locking pin 94 from the insertion hole of the locking plate 91. After the adjustment is in place, the pressing block 98 is released, and the locking pin 94 will automatically spring into the new insertion hole position under the elastic force of the spring 96, completing the locking.
