Description
Technical Field
[0001] The present invention relates to the technical field of sight processing, and specifically to a barrel drilling device. Background Art
[0002] A sight, or an optical sighting device, its origin is difficult to verify. It is said that at least in the 16th century in Europe, people have tried to fix spectacle lenses on the gunstock. Sights are mainly divided into the following three categories: telescopic sights, collimator sights, and reflex sights. Among them, telescopic sights and reflex sights are the most popular. When the main barrel of the sight is processed, holes need to be drilled on the main barrel to facilitate the installation of an adjustment knob for adjusting the aiming accuracy.
[0003] There are many problems in the prior art when drilling the sight barrel:
[0004] Since sights are usually made of relatively hard metal materials, when drilling, the drill bit will heat up due to hard friction every time it drills through a hole. If continuous drilling is carried out, it is easy to cause serious wear of the drill bit and reduce its service life;
[0005] The barrel diameters at both ends of the sight barrel are different. Before drilling, it is necessary to position both ends separately. The positioning requires manual locking of both ends by hand, and it is very difficult to ensure that the barrel can remain horizontal after positioning, which will cause tilting during drilling. Summary of the Invention
[0006] The technical solution of the present invention provides a solution significantly different from the prior art for the technical problem that the prior art solution is too single. Specifically, the purpose of the present invention is to provide a barrel drilling device to solve the problem that continuous drilling will reduce the service life of the drill bit as mentioned in the above background art.
[0007] To achieve the above purpose, the present invention provides the following technical solution: A barrel drilling device includes a processing box body. A first cylinder is installed on the top of the processing box body. The inner wall of the top end of the first cylinder is connected with a first spring. The bottom of the first spring is connected with a first piston that is slidably matched with the first cylinder. The bottom of the first piston is connected with a first movable rod. The bottom of the first movable rod is fixedly connected with a connecting plate. An air pump is installed on the top of the processing box body. A gas transmission pipeline is connected between the output end of the air pump and the top of the first cylinder. A drilling mechanism is arranged at the bottom of the connecting plate. A positioning mechanism is arranged below the drilling mechanism at the bottom of the processing box body.
[0008] Preferably, the drilling mechanism includes a connecting shaft rotatably connected to the bottom of the connecting plate. The bottom of the connecting shaft is fixedly connected with a mounting plate. Two groups of rotating shafts rotatably connected to the mounting plate are symmetrically arranged on the mounting plate. Drills are installed at the bottoms of the two groups of rotating shafts, and drive shafts are connected to the tops of the two groups of rotating shafts. A transmission belt is arranged between the drive shafts. A motor is installed on the top of the mounting plate. The output end of the motor is connected to the top of one of the drive shafts. A roller is sleeved on the outer wall of the connecting shaft. A ratchet mechanism is arranged between the connecting shaft and the roller. A driving component for driving the roller to rotate is arranged on the connecting plate.
[0009] Preferably, the connecting shaft is located at the center of the top of the mounting plate, and limiting plates are arranged at both ends of the roller on the outer wall of the connecting shaft.
[0010] Preferably, the driving component includes a second cylinder arranged on the connecting plate. The top end of the second cylinder is communicated with the air delivery pipeline through a pipeline. A second spring is connected to the inner wall of the top end of the second cylinder. The bottom of the second spring is connected with a second piston slidably matched with the second cylinder. The bottom of the second piston is connected with a second movable rod. The bottom of the second movable rod is connected with a friction block. A guide rod is connected to the side wall of the second movable rod. A guide groove slidably matched with the guide rod is obliquely opened on the outer wall of the roller.
[0011] Preferably, the positioning mechanism includes a bottom plate arranged on the processing box body. Two groups of fixing rings are symmetrically arranged on the top of the bottom plate. Two groups of clamping components are symmetrically arranged at the centers of the two groups of fixing rings. Each clamping component includes two partition plates arranged inside the fixing ring. A third piston slidably matched with the fixing ring is arranged between the two partition plates. A third spring is connected between the third piston and one of the partition plates. A sliding rod slidably sealed with the fixing ring is arranged on one side of the third piston. The end of the sliding rod is connected with a clamping plate. An arc-shaped plate is arranged on the outer wall of one side of the third piston. A third movable rod slidably sealed with the partition plate is connected between the third piston of one group of clamping components and the arc-shaped plate of the other group of clamping components.
[0012] Preferably, a connecting pipe is connected between the two groups of fixing rings, and the connection part of the connecting pipe is located between the arc-shaped plates close to the partition plates. The connecting pipe is communicated with the air delivery pipeline through a pipeline. Air holes are opened on the outer wall of the fixing ring on one side of one of the partition plates. The clamping plate is arranged in an arc shape, and a rubber pad is arranged on the concave surface of the clamping plate.
[0013] Preferably, the two arc-shaped plates are symmetrically arranged at the center inside the fixing ring. A chute is obliquely opened inside the arc-shaped plate. A sliding column slidably matched with the corresponding chute is arranged on the outer wall of the sliding rod.
[0014] Compared with the prior art, the beneficial effects of the present invention are:
[0015] The present invention, after starting the air pump to inflate, the gas will be first delivered to the fixed ring on the left side, and then delivered to the fixed ring on the right side. With the filling of gas, the third piston slides in the fixed ring and squeezes the third spring, and balances the air pressure on both sides of the third piston when it slides through the air hole. The third piston drives the arc plate to move, and slides in the slide groove through the slide column, so that the arc plate drives the slide rod to slide toward the center of the fixed ring. Under the action of the third movable rod, the two groups of clamping components in one group of fixed rings are symmetrically distributed in the center, so that the two groups of slide rods move close to each other, and the two groups of slide rods drive the two groups of clamping plates to clamp the ends of the lens barrel. Similarly, even if the sizes of the two ends of the lens barrel are different, when inflating, the clamping plates in the two groups of fixed rings will adapt to the sizes of the two ends of the lens barrel and clamp and fix it, and it is convenient and quick to position the lens barrel.
[0016] In the present invention, after clamping the two ends of the lens barrel, the positioned lens barrel and the two sets of fixing rings 71 are located on the same central axis, thereby ensuring the horizontality of the lens barrel after positioning and avoiding the hole groove from being skewed after drilling;
[0017] According to the present invention, after the lens barrel is clamped, gas enters the second cylinder body to push the second piston to slide, and the second piston pulls the second spring, and the second piston drives the second movable rod to move, and the second movable rod moves downward to drive the friction block to press against the top surface of the mounting plate to prevent the drilling mechanism from rotating during drilling. At the same time, the second movable rod drives the guide rod to move downward, and the guide rod slides in the guide groove of the outer wall of the roller column, wherein the opening angle of the guide groove on the outer wall of the roller column is 180°, then the guide rod drives the roller column to rotate clockwise, and under the action of the ratchet mechanism, the roller column rotates on the outer wall of the connecting shaft, and when the drilling is completed and reset, the guide rod drives the roller column to rotate counterclockwise when moving upward, and under the action of the ratchet mechanism, the roller column drives the connecting shaft to rotate 180°, and the third spring loosens the clamped lens barrel, so that the drill bit that has not been drilled can be rotated to the drilling position to drill the next lens barrel, and the drill bit that has been drilled is cooled, thereby improving the service life of the drill bit.

[0029] The positioning mechanism includes a bottom plate 7 arranged on the processing box body 1. Two groups of fixing rings 71 are symmetrically arranged on the top of the bottom plate 7. Two groups of clamping assemblies are symmetrically arranged at the center of the inside of the two groups of fixing rings 71. The clamping assembly includes two groups of partition plates 72 arranged inside the fixing ring 71. A third piston 73 that is slidably matched with the fixing ring 71 is arranged between the two groups of partition plates 72. A third spring 74 is connected between the third piston 73 and one of the partition plates 72. A slide rod 75 that is slidably sealed with the fixing ring 71 is arranged on one side of the third piston 73. A clamping plate 76 is connected to the end of the slide rod 75. An arc-shaped plate 77 is arranged on the outer wall of one side of the third piston 73. A third movable rod 710 that is slidably sealed with the partition plate 72 is connected between the third piston 73 of one group of clamping assemblies and the arc-shaped plate 77 of the other group of clamping assemblies.
[0030] A connecting pipe is connected between the two groups of fixing rings 71, and the connection part of the connecting pipe is located between the arc-shaped plates 77 close to the partition plates 72. And the connecting pipe is communicated with the gas transmission pipeline 4 through a pipeline. Air holes are formed on the outer wall of the fixing ring 71 on one side of one group of partition plates 72. The clamping plate 76 is arranged in an arc-shaped structure, and a rubber pad is arranged on the concave surface of the clamping plate 76.
[0031] The two groups of arc-shaped plates 77 are symmetrically arranged at the center inside the fixing ring 71. A chute 78 is obliquely formed inside the arc-shaped plate 77. A sliding column 79 that is slidably matched with the corresponding chute 78 is arranged on the outer wall of the slide rod 75.
[0032] Working principle: When using this lens barrel drilling and processing device, first, place the lens barrel to be drilled in the two groups of fixing rings 71. The air pump 3 is of the type that can be used for both pumping and charging. And the elastic force of the first spring 21 is greater than the elastic force of the second spring 63, and the elastic force of the second spring 63 is greater than the elastic force of the third spring 74;
[0033] Then, start the motor 56. The motor 56 drives the transmission shaft 54 to rotate. Under the action of the transmission belt 55, the two groups of rotating shafts 52 drive the drill bits 53 to rotate synchronously. Then, start the air pump 3 to inflate. The gas is transported to the air delivery pipe 4. The gas will first be transported into the left fixing ring 71 and at the same time into the right fixing ring 71. As the gas is filled, the third piston 73 slides in the fixing ring 71 and presses the third spring 74, and balances the air pressure on both sides of the third piston 73 during sliding through the air holes. The third piston 73 drives the arc-shaped plate 77 to move. By sliding the sliding column 79 in the sliding groove 78, the arc-shaped plate 77 drives the sliding rod 75 to slide towards the center of the fixing ring 71. Under the action of the third movable rod 710, the two clamping components in one group of fixing rings 71 are symmetrically distributed around the center, so that the two sliding rods 75 move closer to each other. The two sliding rods 75 drive the two clamping plates 76 to clamp the end of the lens barrel, and make the end of the lens barrel centered at the center of the fixing ring 71. Similarly, even if the sizes of the two ends of the lens barrel are different, during inflation, the clamping plates 76 in the two groups of fixing rings 71 will adapt to the sizes of the two ends of the lens barrel and clamp and fix it. And the positioned lens barrel and the two groups of fixing rings 71 are located on the same central axis, thus ensuring the levelness of the lens barrel after positioning;
[0034] After positioning the lens barrel, the third piston 73 cannot continue to slide. The gas enters the second cylinder body 62 and pushes the second piston 64 to slide. And the second piston 64 pulls the second spring 63, and the second piston 64 drives the second movable rod 65 to move. The downward movement of the second movable rod 65 drives the friction block 66 to press against the top surface of the mounting plate 51, preventing the drilling mechanism from rotating during drilling. At the same time, the second movable rod 65 drives the guide rod 67 to move downward. The guide rod 67 slides in the guide groove 68 on the outer wall of the roller 6. The opening angle of the guide groove 68 on the outer wall of the roller 6 is 180°. Then the guide rod 67 will drive the roller 6 to rotate clockwise. Under the action of the ratchet mechanism 61, the roller 6 will rotate on the outer wall of the connecting shaft 5 and be limited by the limit plates at both ends;
[0035] After the friction block 66 abuts against the top surface of the mounting plate 51, the second piston 64 cannot continue to slide, and the gas then starts to push the first piston 22 to slide within the first cylinder body 2. The first piston 22 pulls the first spring 21, and the first piston 22 drives the first movable rod 23 to move downward. The first movable rod 23 drives the connecting plate 24 to move, causing the drilling mechanism to start moving downward. A set of drill bits 53 located above the lens barrel then start to drill. After the drilling is completed, the air pump 3 is started to pump air. The first spring 21 causes the drilling mechanism at the bottom of the connecting plate 24 to start resetting, and the second spring 63 causes the second movable rod 65 to start resetting. When the guide rod 67 moves upward, it drives the roller 6 to rotate counterclockwise. Under the action of the ratchet mechanism 61, the roller 6 drives the connecting shaft 5 to rotate 180°. The third spring 74 loosens the clamped lens barrel, and the undrilled drill bit 53 can be rotated to the drilling position to drill the next lens barrel. The drilled drill bits are then cooled down.
[0036] Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
