Abstract
Description
Technical Field
[0001] The utility model relates to the field of clamping mechanisms, in particular to a clamping mechanism for laser cutting of pipes. Background Technique
[0002] In modern manufacturing, various pipes are an indispensable part. According to requirements, pipes need to be cut. Currently, cutting equipment mainly uses a saw or a laser as the cutting blade. Among them, laser cutting is more cost-effective than saw cutting. There is no problem of blade consumption, and at the same time, noise and pollution are reduced. Moreover, the cutting accuracy is higher, and the production quality compliance rate is relatively high. For existing pipe laser cutting devices, the pipes need to be clamped by a clamping mechanism to facilitate laser cutting.
[0003] The existing clamping mechanism mainly fixes the pipe at the required position through multiple single, double, or quadruple jaw chucks, and a pushing component advances the pipe forward until the laser cuts the pipe completely.
[0004] However, due to slight errors in the use of multiple jaw chucks, when at the laser cutter, the errors will be amplified, resulting in a lot of time being consumed in the early stage to align multiple chucks. It has relatively high requirements for the skills of workers and takes a long time, and the production efficiency is not high. Content of the Utility Model
[0005] Based on this, the purpose of the utility model is to provide a clamping mechanism for laser cutting of pipes to solve the technical problem of easy deviation in clamping of the existing clamping mechanism.
[0006] To achieve the above purpose, the utility model provides the following technical solution: A clamping mechanism for laser cutting of pipes, including a base and a fixed block. A fixed block is fixed on one side of the base. A cylinder is installed inside the fixed block, and a limiting block is fixed at the movable end of the cylinder. A laser cutter is installed at the bottom of the fixed block. A limiting groove is installed on the top of the base. A pushing block is installed on one side of the base, and a connecting rod is fixed on one side of the pushing block. One end of the connecting rod is fixed with a sliding block. A square groove is opened on the top of the base, and a reciprocating lead screw is installed inside the square groove. A square pipe is placed inside the limiting groove.
[0007] By adopting the above technical solution, the problem of easy deviation in clamping of the existing clamping mechanism is solved. When the square pipe is placed in the limiting groove, the pushing block pushes the square pipe forward, and the limiting block presses downwards. The V-shaped inner walls of the limiting groove and the limiting block are used to fit the square pipe, so that the square pipe can only be fixed in one place and will not easily shift, resulting in cutting errors.
[0008] The utility model is further set as follows: A moving block is installed on the top of the pushing block. A cylinder is installed inside the moving block, and a limiting block is fixed at the movable end of the cylinder.
[0009] By adopting the above technical solution, the moving block moves together with the pushing block, and the air cylinder can push the limiting block to always limit one end of the square tube together with the pushing block, preventing the square tube from moving.
[0010] The present utility model is further configured such that a plurality of groups of holes are formed inside the limiting groove, and a universal ball assembly is installed inside the holes.
[0011] By adopting the above technical solution, when the square tube moves, the universal ball assembly can reduce the friction between the square tube and the limiting groove, facilitating the pushing block to push the square tube.
[0012] The present utility model is further configured such that the universal ball assembly includes a limiting shell installed inside a base, and a spring is installed inside the limiting shell, and a steel ball is installed on the top of the spring.
[0013] By adopting the above technical solution, when the spring is in a free state, the steel ball can roll freely, facilitating the movement of the square tube. When the square tube is limited and fixed, the steel ball presses the spring, and the steel ball sinks into the limiting shell, without affecting the limiting and fixing of the square tube.
[0014] The present utility model is further configured such that the cross-section of the limiting groove is V-shaped, and the cross-section of the limiting block is V-shaped.
[0015] By adopting the above technical solution, the two V-shaped limiting slots can clamp the square tube up and down, and the square tube can be limited and fixed at the required position.
[0016] The present utility model is further configured such that the bottom shape of the pushing block fits the cross-section of the limiting groove.
[0017] By adopting the above technical solution, the pushing block can push the square tube installed inside the limiting groove to move forward.
[0018] The present utility model is further configured such that a motor is provided inside the base, and a reciprocating lead screw is connected to the output end of the motor, and circuit elements are provided inside both the fixed block and the moving block.
[0019] By adopting the above technical solution, the reciprocating lead screw can drive the push rod to move back and forth, and the circuit elements of the fixed block and the moving block provide power for the air cylinder inside.
[0020] The present utility model is further configured such that the limiting block installed at the bottom of the fixed block is flush with the limiting groove.
[0021] By adopting the above technical solution, when the laser cutter cuts, the square tube will not warp or tilt, causing the problem of unqualified cutting.
[0022] In summary, the present utility model mainly has the following beneficial effects:
[0023] 1. The utility model solves the problem of easy deviation in clamping of the existing clamping mechanism by setting a fixed block, a moving block, a cylinder, a limiting block, a pushing block, a limiting groove and a reciprocating lead screw. When the square pipe is placed in the limiting groove, the pushing block pushes the square pipe forward, and the limiting block presses downward. The V-shaped inner walls of the limiting groove and the limiting block are used to fit the square pipe, so that the square pipe can only be fixed in one place and will not easily shift, resulting in cutting errors.
[0024] 2. The utility model solves the problem of inconvenient movement of the square pipe by setting a pushing block, a limiting groove and a universal ball assembly. The direct contact between the square pipe and the limiting groove results in a large frictional force. When the universal ball assembly is used to move the square pipe above the steel balls without the limiting block restricting the square pipe, the frictional force is small. When the limiting block restricts the square pipe, the steel balls can be squeezed into the limiting shell without affecting the fitting of the square pipe and the limiting groove.

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.
[0032] The following will explain the embodiments according to the overall structure of the present utility model.
[0033] A clamping mechanism for laser cutting of pipes, as Figure 1 - Figure 5As shown, it includes a base 1 and a fixed block 2, and the fixed block 2 is fixed on one side of the base 1.
[0034] Specifically, a cylinder 4 is installed inside the fixed block 2, and a limiting block 5 is fixed to the movable end of the cylinder 4. When the cylinder 4 inside the fixed block 2 and the moving block 3 starts to work, the limiting block 5 is pushed downward. A laser cutter 12 is installed at the bottom of the fixed block 2, and a limiting groove 9 is installed at the top of the base 1. The limiting block 5 pushes the square tube 13 to closely fit with the limiting groove 9. A push block 6 is installed on one side of the base 1, and a connecting rod 7 is fixed to one side of the push block 6. One end of the connecting rod 7 is fixed with a slider 8. A square groove 101 is opened at the top of the base 1, and a reciprocating lead screw 10 is installed inside the square groove 101. The reciprocating lead screw 10 starts to rotate, and the reciprocating lead screw 10 drives the slider 8 sleeved on the outer wall of the reciprocating lead screw 10 to move forward, so that the push block 6 moves forward and pushes the square tube 13 to move below the laser cutter 12. The square tube 13 is placed inside the limiting groove 9.
[0035] Please refer to Figure 1 - Figure 3 , a moving block 3 is installed on the top of the push block 6, a cylinder 4 is installed inside the moving block 3, and a limiting block 5 is fixed to the movable end of the cylinder 4. The moving block 3 moves together with the push block 6, and the cylinder 4 can push the limiting block 5 to always limit one end of the square tube 13 together with the push block 6 to prevent the square tube 13 from moving.
[0036] Please refer to Figure 4 , multiple groups of holes 91 are opened inside the limiting groove 9, and a universal ball assembly 11 is installed inside the holes 91. When the square tube 13 moves, the universal ball assembly 11 can reduce the friction between the square tube 13 and the limiting groove 9, facilitating the push block 6 to push the square tube 13.
[0037] Please refer to Figure 5 , the universal ball assembly 11 includes a limiting shell 1102 installed inside the base 1, a spring 1103 is installed inside the limiting shell 1102, and a steel ball 1101 is installed on the top of the spring 1103. When the spring 1103 is in a free state, the steel ball 1101 can roll freely, facilitating the movement of the square tube 13. When the square tube 13 is limited and fixed, the steel ball 1101 squeezes the spring 1103, and the steel ball 1101 sinks into the limiting shell 1102, without affecting the limiting and fixing of the square tube 13.
[0038] Please refer to Figure 1 - Figure 4 , the cross-section of the limiting groove 9 is V-shaped, and the cross-section of the limiting block 5 is V-shaped. The two V-shaped limiting grooves can clamp the square tube 13 up and down, and the square tube 13 can be limited and fixed at the required position.
[0039] Please refer to Figure 1 - Figure 3, the bottom shape of the pushing block 6 fits the cross-section of the limiting groove 9, and the pushing block 6 can push the square pipe 13 installed inside the limiting groove 9 to move forward.
[0040] Please refer to Figure 1 - Figure 3 , a motor is provided inside the base 1, and a reciprocating lead screw 10 is connected to the output end of the motor. Circuit elements are provided inside both the fixed block 2 and the moving block 3. The reciprocating lead screw 10 can drive the pushing block 6 to move back and forth, and the circuit elements of the fixed block 2 and the moving block 3 provide power for the cylinder 4 inside.
[0041] Please refer to Figure 1 , the limiting block 5 installed at the bottom of the fixed block 2 is flush with the limiting groove 9, so that when the laser cutter 12 cuts, the square pipe 13 will not warp or tilt, causing the problem of unqualified cutting.
[0042] The working principle of the present utility model is as follows: When it is necessary to cut the square pipe 13, the square pipe 13 is placed in the limiting groove 9, the motor inside the base 1 is started, the reciprocating lead screw 10 starts to rotate, and the reciprocating lead screw 10 drives the slider 8 sleeved on the outer wall of the reciprocating lead screw 10 to move forward, so that the pushing block 6 moves forward and pushes the square pipe 13 to move under the laser cutter 12. The square pipe 13 rolls above the steel balls 1101, and the steel balls 1101 can reduce the friction between the square pipe 13 and the limiting groove 9, facilitating the movement of the square pipe 13.
[0043] Before the laser cutter 12 starts cutting, the cylinders 4 inside the fixed block 2 and the moving block 3 start to work, push the limiting block 5 downward until the limiting block 5 pushes the square pipe 13 to fit tightly with the limiting groove 9, squeeze the steel balls 1101 into the limiting shell 1102, so that the square pipe 13 will not displace. At this time, the laser cutter 12 starts cutting. After cutting, the cut square pipes 13 fall into the storage box below the laser cutter 12. The limiting block 5 moves upward, and the spring 1103 rebounds, so that the steel balls 1101 continue to lift the uncut square pipes 13, facilitating the pushing block 6 to push the square pipe 13 and start the next cutting.
