Description

A lens barrel clamping mechanism Technical Field

[0001] This utility model belongs to the field of metal surface treatment technology, specifically relating to a lens barrel clamping mechanism. Background Technology

[0002] Cylindrical metal parts, such as microscope tubes, are used in microscopes or cameras as housing frames; they are manufactured from metal tubing using cutting processes such as lathes, milling machines, and cam groove machining centers.

[0003] To ensure the scope barrel meets usage standards, the inner wall surface of the scope barrel undergoes deburring. The existing method involves replacing the drill rod of the drilling machine with a brush, which is fixed to the spindle of the drilling machine. The brush bristles rotate, and the operator holds the outer wall of the scope barrel, inserts the scope barrel onto the brush, and rubs the brush against the scope barrel to remove the burrs. After completion, the operator removes the scope barrel from the brush and repeats the process with the next scope barrel.

[0004] Operators often experience arm and arm pain from prolonged work, reducing their grip strength on the lens barrel. If not careful, this can lead to the brush rubbing against their skin, posing a risk. Manual hand-held friction is also subject to subjective factors, with variations in friction time and angle, making it difficult to consistently control product quality. Therefore, a device is needed to replace manual hand-held lens barrel handling. Summary of the Invention

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments;

[0029] This embodiment provides a lens barrel clamping mechanism, including a U-shaped base 01, with pull-back mechanisms 02 installed on both side walls of the base 01, and a first spring 03 clamping between the pull-back mechanisms 02 and the base 01.

[0030] The base 01 is installed on the workbench and bolts pass through the base 01 for fixation; the first spring 03 supports the pull-back mechanism 02, and when the pull-back mechanism 02 is pulled in the opposite direction, the first spring 03 is compressed; when the pull-back mechanism 02 is released, the first spring 03 extends and the pull-back mechanism 02 returns to its original position; the base 01 and the pull-back mechanism are elastically connected.

[0031] It also includes a first pressure plate 04, which is disposed on one side of the pull-back mechanism, and a second spring 05 is clamped between the first pressure plate 04 and the pull-back mechanism;

[0032] The second spring 05 supports the first pressure plate 04, and the first pressure plate 04 is elastically connected to the return mechanism.

[0033] An elastic pad 07 is installed on one side of the first pressure plate 04, and a first slot 070 is formed on the inner side of the elastic pad 07; the lens barrel is clamped between two elastic pads 07. The first pressure plate 04 drives the elastic pads 07 to move;

[0034] As described above, in the specific usage process, the base 01 is installed below the brush. Pulling the pull-back mechanism 02 in the opposite direction causes the first pressure plate 04 and the elastic pads 07 to move in the opposite direction, placing the lens barrel between the two elastic pads 07. Releasing the pressure causes the two elastic pads 07 to move closer together, clamping the lens barrel. Starting the machine allows the brush to descend and remove burrs. After processing, the lens barrel is pulled open and removed. Repeating these actions reduces the operator's workload by only needing to place and retrieve the product. Besides processing lens barrels, other cylindrical metal products can also be processed, such as metal water cup shells.

[0035] Furthermore, the base 01 includes a first base plate 010, and first side plates 011 are provided on opposite edges of the two sides of the first base plate 010; holes are provided on the first base plate 010, and bolts pass through the holes to connect with the workbench and the first side plates 011, so as to achieve a detachable connection without affecting the original function of the equipment; the first base plate 010 and the first side plates 011 are also connected by bolts, which can be replaced to match products of different specifications.

[0036] The pull-back mechanism 02 includes a first handle 020, one end of which is connected to a pull member 021; the first handle 020 is frustoconical in shape for easy gripping, and the pull member 021 is a metal block.

[0037] One end of the first guide rod is connected to the pull member 021. The first guide rod passes through the first side plate 011, and the other end of the first guide rod is connected to the first connecting plate 022. The first guide rod is a metal cylinder, and the first connecting plate 022 is moved by the first guide rod.

[0038] The first connecting plate 022 has a C-shaped cross section. The first spring 03 is sandwiched between the middle wall of the first connecting plate 022 and the first side plate 011. The first spring 03 is sleeved on the first guide rod. The top and bottom walls of the first connecting plate 022 are provided with first threaded pits 0220. The first connecting plate 022 is made of metal plate.

[0039] The first pressure plate 04 has a C-shaped cross-section. First oblong holes 040 are provided on both the top and bottom walls of the first pressure plate 04. A first bolt 041 passes through the first oblong hole 040 and connects to a first threaded hole. A second spring 05 is sandwiched between the middle wall of the first pressure plate 04 and the middle wall of the first connecting plate 022. The first pressure plate 04 is also made of metal plate, and the two are nested together. The first bolt 041 is inserted into the first oblong hole 040, serving as a connection and limiting mechanism. The first pressure plate 04 can only move within the range of the first oblong hole 040. Simultaneously, the first bolt 041 connects the first connecting plate 022 to the first pressure plate 04, and the first connecting plate 022 drives the first pressure plate 04 to move. The second spring 05 is used to support the two plates, allowing for elastic gap adjustment. The first spring 03 also provides more compression margin, making it suitable for large-sized products.

[0040] The middle wall of the first pressure plate 04 is connected to the elastic pad 07 by bolts; the bolts pass through the first pressure plate 04 and are connected to the elastic pad 07; the elastic pad 07 can be a silicone pad, rubber pad, or other elastic material.

[0041] It also includes a ball screw 06, which is threaded to the top and bottom walls of the first connecting plate 022. The ball bearings of the ball screw 06 support the top and bottom walls of the first pressure plate 04. The ball screw 06 supports the first pressure plate 04, restricting its wobbling and ensuring stability during deburring.

[0042] As described above, in the specific usage process, the operator pulls open the first handle 020 on one side, the first guide rod moves accordingly, driving the first connecting plate 022 and the first pressure plate 04 to move in the opposite direction, the elastic pad 07 separates, the lens barrel is inserted, the first handle 020 is released, the first spring 03 and the second spring 05 return to their original positions, and the elastic pad 07 clamps the lens barrel.

[0043] Furthermore, a first through groove 0110 is provided on the top surface of the first side plate 011, and a first through hole 0111 is provided on the bottom surface of the first side plate 011.

[0044] As described above, the first through groove 0110 is used to provide a clearance effect for the top walls of the first connecting plate 022 and the first pressure plate 04; the first through hole 0111 is used to provide a clearance effect for the bottom walls of the first connecting plate 022 and the first pressure plate 04; pulling in the opposite direction will not cause a collision, and at the same time, it will increase the displacement.

[0045] Furthermore, the upper and lower ends of the pull member 021 are respectively provided with first countersunk holes 0210;

[0046] The first side plate 011 has a second countersunk hole 0112 that is directly opposite to the first countersunk hole 0210; it also includes a first bushing 023, one end of the first bushing 023 is inserted into the second countersunk hole 0112 and fixed by a bolt, and the other end of the first bushing 023 is inserted into the first countersunk hole 0210; the first bushing 023 plays a limiting and guiding role for the first guide rod, which facilitates the movement of the first guide rod;

[0047] The first guide rod passes through the first bushing 023 and is inserted into the first countersunk hole 0210 and is connected by bolts. The first spring 03 presses against the first bushing 023.

[0048] As described above, in Figure 3, one end of the first guide rod is inserted into the second countersunk hole 0112, and the bolt passes through the puller 021 and is connected to the first guide rod. The other end of the first guide rod is threadedly connected to the first connecting plate 022. Two first bushings 023 are provided to make the movement more stable and the upper and lower clamping tubes are subjected to uniform force.

[0049] In another embodiment, a first guide rod is installed in the middle of the pull member 021;

[0050] Furthermore, two first oblong holes 040 are respectively opened on the top and bottom walls of the first pressure plate 04, and four first bolts 041 pass through the first oblong holes 040 and connect to the first threaded holes.

[0051] The two first oblong holes 040 limit the movement of the first pressure plate 04, ensuring smooth movement without any deviation.

[0052] A first blind hole 0221 is formed by a recess on the middle wall of the first connecting plate 022, and a second blind hole 042 is formed by a recess on the middle wall of the first pressure plate 04. The two ends of the second spring 05 are respectively inserted into the first blind hole 0221 and the second blind hole 042 for fixation.

[0053] As described above, the two ends of the second spring 05 are respectively inserted into the blind holes to prevent the second spring 05 from falling out;

[0054] Furthermore, the first slot 070 is V-shaped, and clearance pits 071 are provided on both sides of the first slot 070.

[0055] As mentioned above, the first slot 070 has a larger opening on the outside and a smaller opening on the inside, which can better clamp cylindrical products; the clearance pit 071 is suitable for products with larger diameters and is more practical.
