[0002] Metallic materials are a class of materials widely used in various industrial and construction fields. They possess many unique physical and chemical properties, such as electrical conductivity, thermal conductivity, and corrosion resistance. Metal processing refers to the engineering process of transforming raw metallic materials into desired shapes, sizes, and properties through various methods and processes. Different combinations of processing methods and processes can meet various application requirements regarding material properties, precision, and appearance.

[0003] A search revealed that patent CN221936478U discloses an adjustable clamping device for metal material testing. By incorporating a cylinder, telescopic rod, fixed rod, connecting seat, rotating sleeve, and rotating shaft, it allows for convenient multi-angle adjustment of metal materials, making the metal material testing process more convenient and improving the testing effect and efficiency. Furthermore, by including a clamping seat, clamping arm, clamping disc, screw, and rotating wheel, it can effectively clamp metal materials according to their size, improving the stability of the clamping process and further enhancing the practicality of the equipment.

[0004] While the above solution can effectively clamp metal materials of different sizes, it is difficult to effectively clamp and fix the workpiece using the clamping disc and rubber anti-slip pad when the two clamped surfaces of the workpiece are not parallel or the clamped surfaces are not a single plane. This needs to be improved. Utility Model Content

[0005] The purpose of this invention is to provide an adjustable clamping device for testing metal materials, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] An adjustable clamping device for metal material testing includes a column, a mounting frame connected to the column via a lifting mechanism, a second reduction motor fixedly mounted inside the mounting frame, a connecting seat fixedly connected to the output shaft of the second reduction motor, a slide block slidably mounted on the outer wall of the connecting seat, a bidirectional drive mechanism provided inside the connecting seat for driving two slide blocks to move simultaneously in opposite directions, a U-shaped tube fixedly connected to the outer wall of the slide block, two push rods slidably mounted through through holes in the outer wall of the slide block, both ends of the U-shaped tube communicating with corresponding through holes, a clamping plate hinged to the end of each push rod outside the slide block, and steel balls filling both the U-shaped tube and the through holes.

[0008] As a further embodiment of this utility model: the outer wall of the top rod is provided with a guide groove, and both outer walls of the slide are provided with positioning pins, one end of which is located in the corresponding guide groove.

[0009] As a further embodiment of this utility model: a spring is provided in one end of the guide groove located in the through hole, one end of the spring abuts against the positioning pin, and the other end of the spring abuts against the inner wall of the guide groove.

[0010] As a further embodiment of this utility model: the bidirectional drive mechanism includes a bidirectional screw rotatably installed in the connecting seat. The bidirectional screw is symmetrically fitted with two second threaded blocks on the outer wall of the connecting seat. Each of the second threaded blocks has a threaded hole adapted to the bidirectional screw. The second threaded blocks are fixedly connected to the corresponding slide block. One end of the bidirectional screw passes through the connecting seat and is fixedly connected to a handwheel.

[0011] As a further embodiment of this utility model: the lifting mechanism includes a first screw rod rotatably installed inside the column, a first reduction motor is fixedly installed at the top of the column, the output shaft of the first reduction motor is fixedly connected to the top of the first screw rod, a first threaded block is fitted onto the outer wall of the first screw rod, the first threaded block has a threaded hole adapted to the first screw rod, and the first threaded block is fixedly connected to the mounting bracket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] In this invention, the two slide blocks are brought closer together by a bidirectional drive mechanism, which allows the clamping plate to contact the workpiece surface. This pushes the push rod to slide into the through hole, and the corresponding push rod is pushed out of the through hole by steel balls until the clamping plates at the ends of the four push rods are in close contact with the workpiece surface. This achieves the fixation and clamping of the workpiece. The operation is simple and convenient, and it can adapt to the fixation of different types of irregular material workpieces, with good performance. Attached Figure Description

[0018] The components include: column 1, first geared motor 2, first screw 3, first threaded block 4, mounting bracket 5, second geared motor 6, connecting seat 7, double screw 8, handwheel 9, second threaded block 10, slide 11, through hole 12, U-tube 13, steel ball 14, top rod 15, clamping plate 16, guide groove 17, positioning pin 18, and spring 19. Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figures 1-4 In this embodiment of the present invention, an adjustable clamping device for metal material testing includes a column 1. A mounting frame 5 is connected to the column 1 via a lifting mechanism. A second reduction motor 6 is fixedly installed inside the mounting frame 5. The output shaft of the second reduction motor 6 is fixedly connected to a connecting seat 7, and the connecting seat 7 is rotatably connected to the mounting frame 5 via a turntable bearing. A slide block 11 is slidably installed on the outer wall of the connecting seat 7. A bidirectional drive mechanism is provided inside the connecting seat 7. The bidirectional drive mechanism is used to drive two slide blocks 11 to move in opposite directions simultaneously. A U-shaped tube 13 is fixedly connected to the outer wall of the slide block 11. Two top rods 15 are slidably installed through a through hole 12 on the outer wall of the slide block 11. Both ends of the U-shaped tube 13 are connected to the corresponding through hole 12. A clamping plate 16 is hinged to the end of each top rod 15 outside the slide block 11. Steel balls 14 are filled in both the U-shaped tube 13 and the through hole 12.

[0021] By adopting the above-mentioned scheme, this utility model places an irregular material workpiece between two slide blocks 11, and then uses a bidirectional drive mechanism to bring the two slide blocks 11 closer together, so that the clamping plate 16 contacts the workpiece surface, thereby pushing the push rod 15 to slide into the through hole 12, and using the steel ball 14 to push the corresponding push rod 15 to move out of the through hole 12 until the clamping plate 16 at the ends of the four push rods 15 are in close contact with the workpiece surface, thus achieving the fixation and clamping of the workpiece. The operation is simple and convenient, and it can adapt to the fixation of different types of irregular material workpieces, with good performance.

[0022] Specific combination Figure 3 In one embodiment of the present invention, the outer wall of the top rod 15 is provided with a guide groove 17, and both outer walls of the slide block 11 are provided with positioning pins 18, one end of the positioning pin 18 being located in the corresponding guide groove 17.

[0023] The guide groove 17 and the positioning pin 18 work together to limit the range of motion of the push rod 15 within the through hole 12, so as to prevent the push rod 15 from coming out of the through hole 12.

[0024] Specific combination Figure 3 Furthermore, based on the previous embodiment, each end of the guide groove 17 located within the through hole 12 is provided with a spring 19, one end of the spring 19 abutting against the positioning pin 18, and the other end of the spring 19 abutting against the inner wall of the guide groove 17.

[0025] Through the cooperation of spring 19 and positioning pin 18, a thrust can always be applied to push rod 15 to move into through hole 12, so that when the workpiece is not clamped, the steel ball 14 can be used to keep the length of the two push rods 15 extending out of slide 11 consistent.

[0026] Specific combination Figure 2 In one embodiment of the present invention, the bidirectional drive mechanism includes a bidirectional screw 8 rotatably installed in the connecting seat 7. Two second threaded blocks 10 are symmetrically fitted on the outer wall of the bidirectional screw 8 inside the connecting seat 7. Each of the second threaded blocks 10 has a threaded hole adapted to the bidirectional screw 8. The second threaded blocks 10 are fixedly connected to the corresponding slide block 11. One end of the bidirectional screw 8 passes through the connecting seat 7 and is fixedly connected to a handwheel 9.

[0027] By rotating the double-acting screw 8 with the handwheel 9, the two slide blocks 11 can be driven to move in opposite directions simultaneously by the engagement of the double-acting screw 8 with the threaded hole on the second screw block 10. The operation is simple and convenient.

[0028] Specific combination Figure 1 In one embodiment of the present invention, the lifting mechanism includes a first screw 3 rotatably installed inside the column 1, a first reduction motor 2 fixedly installed at the top of the column 1, the output shaft of the first reduction motor 2 being fixedly connected to the top of the first screw 3, a first thread block 4 being fitted onto the outer wall of the first screw 3, the first thread block 4 having a threaded hole adapted to the first screw 3, and the first thread block 4 being fixedly connected to the mounting bracket 5.

[0029] The first geared motor 2 is started to drive the first screw 3 to rotate. The screw 3 and the threaded hole on the first screw block 4 are used to drive the mounting bracket 5 to move up and down, so as to adjust the height of the material workpiece.

[0030] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
