Description

Technical Field

[0001] This utility model relates to the field of welding technology, and in particular to a sample clamping device suitable for laser butt welding. Background Technology

[0002] During laser welding, the large heat input of the laser heats the weld area in a very short time, causing it to melt and then rapidly cool and solidify to form the weld. Excessively rapid heating and cooling rates can cause deformation in the localized heat-affected zone due to drastic temperature changes, leading to weld misalignment or defective joints, affecting its mechanical properties. To eliminate this effect, the substrates on both sides need to be clamped and fixed during welding to prevent displacement and warping during thermal expansion, creating bidirectional compressive stress. This increases the size of the weld nugget and plastic ring, minimizing keyholes and defects in the weld pool, thereby improving the strength of the weld joint.

[0003] Application number CN202023258507.7 discloses a board fixing fixture for processing household wardrobes, including support legs and other structures. Several sets of springs are set under the fixing plate. The clamps press down to fix the board to the fixing plate. When the clamps are too tight, the downward pressure is buffered by the springs and distributed to all parts of the board, thereby effectively protecting the board and preventing it from being damaged by excessive force. When the clamps are too loose, the board will be subjected to the upward pressure of the fixing plate, making the fixation more secure and improving the performance. At the same time, the outer frame can be rotatably connected to the frame via a pivot. During cleaning, simply rotate and tilt the outer frame to pour the wood chips and dust into the dust collection box. Cleaning is very convenient, saving time and effort, and is convenient for our production and use.

[0004] In practical use, each time the board is fixed, the screws need to be tightened one by one in order to compress multiple areas of the board. Although this method is simple, it is very inconvenient to operate. Utility Model Content

[0005] The main objective of this invention is to provide a sample clamping device suitable for laser butt welding, which can effectively solve the problems in the background art.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0007] A sample clamping device suitable for laser butt welding includes a support mechanism, a clamping mechanism, and a loading and unloading mechanism. The support mechanism includes a fixed plate and a slot on the top of the fixed plate. The clamping mechanism includes multiple bearings embedded in the top of the fixed plate, screws movably connected to the bearings, and two pressure bars located on both sides of the slot and connected between the two screws. The loading and unloading mechanism includes two plate sleeves connected to the fixed plate, a horizontal plate sliding through the plate sleeves, multiple toothed blocks connected to the top of the horizontal plate, and a connecting rod connecting the two horizontal plates. The multiple toothed blocks are evenly spaced and arranged in four rows, with each of the four rows of toothed blocks meshing with one of the four screws.

[0008] Preferably, the fixing plate is rectangular, and the bent part of the fixing plate is processed into an arc surface. This shape design reduces the probability of the operator being injured by the bent part of the fixing plate, and improves the safety of the device during use.

[0009] Preferably, the pressure strip consists of a plate and two protrusions, with the two protrusions located near both ends of the pressure strip. The protrusions are integrally formed with the plate. The top of the fixing plate has a slot suitable for inserting the protrusions. The depth of the slot is equal to the height of the protrusions. The structural design of the pressure strip allows it to fit completely against the top of the fixing plate, ensuring that the fixing plate and the pressure strip can clamp extremely thin plates, thus improving the applicability of this device.

[0010] Preferably, multiple bearings are located on the outside of multiple protrusions, and the top of the bearings is flush with the top of the fixing plate. This layout design ensures that the rotation of the screw is not affected by the protrusions.

[0011] Preferably, the screw is T-shaped, and the outer edge of the top of the screw has multiple notches. The multiple notches are evenly spaced and arranged in a ring. This structural design allows the screw to rotate smoothly and the pressure bar to rise and fall smoothly.

[0012] Preferably, the pressure strip is located between two horizontal plates, and the top of the horizontal plates is flush with the top of the pressure strip. With this layout design, the movement of the horizontal plates will not be obstructed by the pressure strip, ensuring that the horizontal plates can move smoothly.

[0013] Preferably, the connecting rod is U-shaped and located on one side of the fixed plate. This shape design makes it convenient for the operator to pull the connecting rod.

[0014] Preferably, the fixing plate is screwed with multiple threaded fasteners arranged in a matrix. The use of threaded fasteners facilitates the connection of the fixing plate to external equipment, and the layout design ensures that the fixing plate can be securely installed.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. In this utility model, the plate is inserted between the fixing plate and the pressure strip, and then the connecting rod is pulled outward from the fixing plate. Then, the two horizontal plates move horizontally with multiple rows of toothed blocks. The toothed blocks affect the rotation of the screw, and the screw affects the lifting and lowering of the pressure strip. When the bottom of the pressure strip squeezes the top of the plate, the connecting rod is stopped. When disassembling the plate, it is only necessary to push the connecting rod inward from the fixing plate. This makes it convenient for operators to remove the plate, optimizes the loading and unloading steps, improves the clamping and disassembly of the plate, and enhances the comfort of use.

[0017] 2. In this utility model, the fixing plate is installed on the external laser welding equipment by multiple threaded fasteners. The layout design of the threaded fasteners ensures that the fixing plate can be firmly installed, thereby improving the overall structural stability of the device. Attached Figure Description

[0030] The loading and unloading mechanism 300 includes two plate sleeves 310 connected to the fixed plate 110, a horizontal plate 320 that slides through the plate sleeves 310, a plurality of toothed blocks 330 connected to the top of the horizontal plate 320, and a connecting rod 340 connecting the two horizontal plates 320. The plurality of toothed blocks 330 are evenly spaced and arranged in four rows, and the four rows of toothed blocks 330 respectively mesh with four screws 220.

[0031] Furthermore, the fixing plate 110 is rectangular, and the bent part of the fixing plate 110 is processed into an arc surface. This shape design reduces the probability of the operator being injured by the bent part of the fixing plate 110, and improves the safety of the device during use.

[0032] Preferably, the pressure strip 230 is composed of a plate 231 and two protrusions 232. The two protrusions 232 are respectively close to both ends of the pressure strip 230. The protrusions 232 are integrally formed with the plate 231. The top of the fixing plate 110 is provided with a slot 233 suitable for the protrusions 232 to be inserted. The depth of the slot 233 is equal to the height of the protrusions 232. The structural design of the pressure strip 230 allows the pressure strip 230 to fit completely against the top of the fixing plate 110, ensuring that the fixing plate 110 and the pressure strip 230 can clamp extremely thin plates, thus improving the applicability of this device.

[0033] Preferably, multiple bearings 210 are located on the outside of multiple protrusions 232, and the top of the bearings 210 is flush with the top of the fixing plate 110. This layout design ensures that the rotation of the screw 220 is not affected by the protrusions 232.

[0034] Preferably, the screw 220 is T-shaped, and the outer edge of the top end of the screw 220 is provided with multiple notches. The multiple notches are evenly spaced and arranged in a ring. This structural design allows the screw 220 to rotate smoothly and the pressure bar 230 to rise and fall smoothly.

[0035] Preferably, the pressure strip 230 is located between two horizontal plates 320, and the top of the horizontal plate 320 is flush with the top of the pressure strip 230. With this layout design, the movement of the horizontal plate 320 will not be obstructed by the pressure strip 230, ensuring that the horizontal plate 320 can move smoothly.

[0036] Preferably, the connecting rod 340 is U-shaped and located on one side of the fixed plate 110. This shape design makes it convenient for operators to pull the connecting rod 340.

[0037] Preferably, the fixing plate 110 is screwed with a plurality of threaded fasteners 400, which are arranged in a matrix. The threaded fasteners 400 facilitate the connection of the fixing plate 110 to external equipment, and their layout design ensures that the fixing plate 110 can be securely installed.

[0038] Working principle: In this utility model, the fixing plate 110 is installed on the external laser welding equipment by multiple threaded fasteners 400. Then, the plate is inserted between the fixing plate 110 and the pressure bar 230. Then, the connecting rod 340 is pulled outward from the fixing plate 110. Then, the two horizontal plates 320 move horizontally with multiple rows of toothed blocks 330. Then, the toothed blocks 330 affect the rotation of the screw 220, and the screw 220 affects the lifting and lowering of the pressure bar 230. When the bottom of the pressure bar 230 squeezes the top of the plate, the pulling of the connecting rod 340 is stopped, and the welding operation begins. Then, when removing the welded plate, the connecting rod 340 is pushed inward from the fixing plate 110. Under the same material, the screw 220 reverses, and then the pressure bar 230 stops squeezing the plate, thereby loosening the plate and making it easier for the operator to remove the plate. This optimizes the loading and unloading steps, improves the clamping and disassembly of the plate, and improves the comfort of use.
