Abstract
Description
Technical Field
[0001] This utility model relates to the field of waterjet cutting technology, specifically to a clamping device based on a linkage mechanism. Background Technology
[0002] Waterjet cutting, also known as high-pressure water jet cutting, is favored for its ability to cut materials without altering their physical and chemical properties. Through continuous technological improvements, abrasives such as garnet and corundum have been added to the high-pressure water to assist cutting, significantly increasing the cutting speed and thickness.
[0003] Patent publication number CN218745609U discloses a clamping mechanism for laser cutting, including a worktable. A support base is fixedly connected to one side of the top of the worktable. A moving mechanism and a clamping mechanism are provided on the side of the top of the worktable. The moving mechanism includes a circular hole opened at the center of one side of the support base. A cylinder is inserted through the inner wall of the circular hole. A rack is provided in the middle of the outer wall of the cylinder. A gear is meshed with one side of the rack. A transmission shaft is fixedly connected to the center of the gear. A partition is provided on one side of the gear. One end of the transmission shaft is movably connected to one side of the partition. A motor is fixedly connected to one side of the partition.
[0004] To address the issue of adapting to workpieces of varying widths, existing technologies employ a method where a motor drives a gear to rotate, which in turn drives a rack forward, causing the cylinder to propel the base forward. However, this approach still fails to achieve underwater cutting, and due to the characteristics of waterjet cutting, the chuck is particularly prone to jamming due to the entry of quartz sand, thus affecting processing efficiency.

[0005] The purpose of this invention is to provide a clamping device based on a linkage mechanism to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0007] A clamping device based on a linkage mechanism includes a fixed base, the surface of which is provided with a telescopic component, and the surface of which is provided with a clamping mechanism.
[0008] The clamping mechanism includes a support platform, which is fixedly installed on the surface of the telescopic component. The surface of the support platform is provided with limit holes. Support columns are fixedly installed on the surface of the support platform. The support columns are L-shaped and there are four sets of them.

[0015] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows:
[0016] 1. This utility model provides a clamping device based on a linkage mechanism. It employs a support platform, support column, first connecting rod, support rod, support plate, second connecting rod, adjusting column, movable column, fixed block, L-shaped connecting rod, and clamping block. By fitting a round tube onto the clamping mechanism, the support platform supports the round tube. At this time, the telescopic component pulls the movable column, which in turn moves the fixed block downwards. The L-shaped connecting rod on the surface of the fixed block rotates in a circle around the fixed block until the clamping block on the surface of the L-shaped connecting rod clamps the top of the round tube. Simultaneously, one end of the L-shaped connecting rod presses downwards, causing the adjusting column to push the support rod outwards. The first and second connecting rods on the surface of the support column, in conjunction with the support rod, push the support plate until the support plate supports and fixes the round tube, completing the clamping process and improving the adaptability of the device.
[0017] 2. This utility model provides a clamping device based on a linkage mechanism, which uses a cylinder, a first push rod, a second push rod, and a limiting post. When a round tube needs to be clamped, the cylinder retracts, causing the first push rod to move downward. At this time, the first push rod causes the second push rod to move downward. The limiting post prevents the second push rod from moving. The second push rod pulls the movable post, causing the clamping mechanism to clamp the round tube. When it is necessary to remove the round tube, the first push rod pushes the second push rod, causing the second push rod to push the movable post. When the clamping mechanism no longer clamps the round tube, the round tube can be removed, thus improving the adaptability of the device. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to embodiments:
[0025] Example 1
[0026] like Figure 1-5As shown, this utility model provides a clamping device based on a linkage mechanism, including a fixed base 1. A telescopic assembly 3 is provided on the surface of the fixed base 1. A clamping mechanism 2 is provided on the surface of the telescopic assembly 3. The clamping mechanism 2 includes a support platform 201, which is fixedly installed on the surface of the telescopic assembly 3. Limit holes are provided on the surface of the support platform 201. Support columns 202 are fixedly installed on the surface of the support platform 201. The support columns 202 are L-shaped and there are four sets of them. The support columns 202 are equidistantly distributed on the top of the support platform 201. First connecting rods 203 are movably installed on the surface of the support columns 202. Four sets of first connecting rods 203 are evenly distributed on the surface of the support columns 202. A support rod 204 is movably mounted at one end, a support plate 205 is fixedly mounted on the surface of the support rod 204, a second connecting rod 206 is movably mounted on the surface of the support rod 204, one end of the second connecting rod 206 is fixedly mounted on the top of the support column 202, an adjusting column 207 is movably mounted on the surface of the support rod 204, the clamping mechanism 2 also includes an L-shaped connecting rod 210, the L-shaped connecting rod 210 is fixedly mounted on the adjusting column 207, a clamping block 211 is fixedly mounted at one end of the adjusting column 207, a fixing block 209 is movably mounted on the surface of the clamping block 211, a movable column 208 is fixedly mounted at the bottom end of the fixing block 209, the movable column 208 is movably mounted inside the support column 202, and the support column 202 is fixedly mounted on the top of the telescopic assembly 3.
[0027] In this embodiment, by fitting the round tube onto the clamping mechanism 2, the support platform 201 supports the round tube. At this time, the telescopic component 3 pulls the movable column 208, which drives the fixed block 209 to move downward. The L-shaped connecting rod 210 on the surface of the fixed block 209 moves in a circle around the fixed block 209 until the clamping block 211 on the surface of the L-shaped connecting rod 210 clamps the top of the round tube. At the same time, one end of the L-shaped connecting rod 210 presses downward, causing the adjusting column 207 to push the support rod 204 to expand outward. The first connecting rod 203 and the second connecting rod 206 on the surface of the support column 202 cooperate with the support rod 204 to push the support plate 205 until the support plate 205 supports and fixes the round tube, completing the clamping and improving the adaptability of the device.
[0028] Example 2
[0029] like Figure 1-5As shown, based on Embodiment 1, this utility model provides a technical solution: Preferably, the telescopic component 3 includes a cylinder 31, which is fixedly installed at the bottom end of the fixed base 1. A first push rod 32 is movably installed on the surface of the cylinder 31, and a second push rod 33 is fixedly installed on the surface of the first push rod 32. The second push rod 33 extends into the interior of the support platform 201 and is fixedly connected to the movable column 208. A limiting column 34 is movably installed on the surface of the second push rod 33. The limiting column 34 is fixedly installed at the top end of the fixed base 1 and at the bottom end of the support platform 201. The second push rod 33 extends into the interior of the support platform 201 and is fixedly connected to the movable column 208. The limiting column 34 is movably installed on the surface of the second push rod 33. The limiting column 34 is fixedly installed at the top end of the fixed base 1 and at the bottom end of the support platform 201.
[0030] In this embodiment, when the round tube needs to be clamped, the cylinder 31 retracts, causing the first push rod 32 to move downward. At this time, the first push rod 32 causes the second push rod 33 to move downward. The limiting post 34 prevents the second push rod 33 from moving. The second push rod 33 pulls the movable post 208, causing the clamping mechanism 2 to clamp the round tube. When the round tube needs to be removed, the first push rod 32 pushes the second push rod 33, causing the second push rod 33 to push the movable post 208. When the clamping mechanism 2 no longer clamps the round tube, the round tube can be removed, improving the adaptability of the device.
[0031] In this embodiment, it is done.
[0032] The working principle of this clamping device based on a linkage mechanism will be explained in detail below.
[0033] like Figure 1-5 As shown, by fitting the round tube onto the clamping mechanism 2, the support platform 201 supports the round tube. The cylinder 31 retracts, causing the first push rod 32 to move downwards. At this time, the first push rod 32 causes the second push rod 33 to move downwards. The limiting post 34 prevents the second push rod 33 from moving. The second push rod 33 pulls the movable post 208, which causes the fixed block 209 to move downwards. The L-shaped connecting rod 210 on the surface of the fixed block 209 moves in a circular motion around the fixed block 209 until the clamping block 211 on the surface of the L-shaped connecting rod 210 clamps the round tube. The top end is clamped, and at the same time, one end of the L-shaped connecting rod 210 is pressed, causing the adjusting column 207 to push the support rod 204 outward. The first connecting rod 203 and the second connecting rod 206 on the surface of the support column 202 cooperate with the support rod 204 to push the support plate 205 until the support plate 205 supports and fixes the round tube, thus completing the clamping. When it is necessary to remove the round tube, the first push rod 32 pushes the second push rod 33, which pushes the movable column 208. When the clamping mechanism 2 no longer clamps the round tube, the round tube can be removed, which improves the adaptability of the device.
[0034] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
