Description
Technical Field
[0001] The utility model belongs to the field of heat treatment auxiliary devices, and particularly relates to a sample clamping device for heat treatment experiments. Background Technique
[0002] Heat treatment is a metal hot working process that obtains the expected structure and properties through a series of treatment methods such as annealing, normalizing, quenching, and tempering. During the heat treatment process of workpieces, clamping devices are often used to complete operations such as the entry and exit of workpieces from the furnace, heating, and cooling. To reduce the deformation of workpieces during clamping, the commonly used heat treatment clamping devices in actual production usually have the inner wall shape of the clamping end fitting the outer wall shape of the workpiece, so as to increase the contact area between the workpiece and the clamping device, reduce the force deformation of the workpiece, and improve the stability effect during the clamping process to prevent the workpiece from falling during the movement. However, during the heat treatment experiment process, the types and shapes of test samples are diverse, and a single-style clamping device cannot be applied to different test samples, which is not convenient and safe during the heat treatment experiment of samples. Content of the Utility Model
[0003] The purpose of the utility model is to provide a sample clamping device for heat treatment experiments, so as to solve the technical problems that during the heat treatment experiment process, the types and shapes of test samples are diverse, a single-style clamping device cannot be applied to different test samples, and it is not convenient and safe during the heat treatment experiment of samples.
[0004] To achieve the above purpose, the specific technical solution of a sample clamping device for heat treatment experiments of the utility model is as follows:
[0005] A sample clamping device for heat treatment experiments includes an extension rod; a fixing member is fixedly arranged at one end of the extension rod; clamping heads are symmetrically and rotatably arranged on both sides of the fixing member away from the extension rod; an arc-shaped connecting rod is rotatably arranged on one side of the clamping head; a moving block is rotatably arranged in the fixing member at the ends of the two arc-shaped connecting rods away from the clamping head; a cylinder is arranged inside the extension rod near the fixing member; one side of the moving block opposite to the cylinder is fixedly connected to the cylinder head; a sliding groove is arranged in the middle of the opposite sides of the two clamping heads; a plurality of clamping pads are arranged side by side in the sliding groove; a spring is arranged between the clamping pad and the clamping head; a control button is arranged at the end of the extension rod away from the fixing member.
[0006] Furthermore, the clamping pad is composed of a plurality of independently arranged cushion blocks; springs are arranged between each cushion block and the clamping head.
[0007] Furthermore, multiple groups of anti-slip lines are arranged on both sides of the cushion block.
[0008] Furthermore, a fastening knob is arranged at the end of the clamping head away from the fixing member at a position opposite to the clamping pad through threaded connection.
[0009] The sample clamping device for heat treatment experiments of the present utility model has the following advantages: By arranging a cylinder inside the extension rod, the cylinder is used to push the moving block. The movement of the moving block drives the arc-shaped connecting rod to push the chuck to rotate on the fixing piece. The chuck is used to clamp and move or place the heat treatment sample. By driving the chuck to clamp the sample with the cylinder, compared with the conventional manually operated clamping device, the clamping force can be preset and adjusted, meeting the clamping requirements of different workpiece samples. The clamping process is more stable. The manually operated clamping device is often limited by the skills and hand strength of the operator and is difficult to maintain long-term stable clamping. Moreover, the clamping driven by the cylinder can effectively reduce the labor intensity of the operator and increase work efficiency. By slidingly arranging a plurality of clamping pads inside the two chucks and cooperating with the springs arranged between the clamping pads, when clamping the sample, the protruding position of the sample will squeeze the opposite clamping pad, causing the opposite spring to compress. The clamping pads opposite to the concave position of the sample will protrude relatively under the thrust of the spring, so that the plurality of clamping pads arranged on the chuck form a shape that fits the outer wall of the sample as a whole. Then, the positions of the plurality of clamping pads are fixed by the fastening knobs, which is convenient for clamping and using this sample, increasing the contact area between the workpiece and the chuck and the clamping pads, reducing the force-induced deformation of the workpiece, and increasing the stability effect during the clamping process, preventing the workpiece from falling during the movement and reducing sample damage.

[0015] In order to better understand the purpose, structure and function of the present utility model, the following will further describe in detail a sample clamping device for heat treatment experiments of the present utility model with reference to the accompanying drawings.
[0016] As Figures 1-4As shown in the figure, a sample clamping device for heat treatment experiments of the present utility model includes an extension rod 1; a fixing member 2 is fixedly arranged at one end of the extension rod 1; clamping heads 3 are symmetrically and rotatably arranged on both sides of the end of the fixing member 2 away from the extension rod 1; an arc-shaped connecting rod 4 is rotatably arranged on one side of the clamping head 3; a moving block 5 is rotatably arranged in the fixing member 2 at the ends of the two arc-shaped connecting rods 4 away from the clamping head 3; a cylinder 6 is arranged inside the end of the extension rod 1 close to the fixing member 2; one side of the moving block 5 opposite to the cylinder 6 is fixedly connected to the cylinder head of the cylinder 6; a sliding groove 301 is arranged in the middle of the opposite sides of the two clamping heads 3; a plurality of clamping pads 7 are arranged side by side in the sliding groove 301; a spring 8 is arranged between the clamping pad 7 and the clamping head 3; a control button 9 is arranged at the end of the extension rod 1 away from the fixing member 2; a fastening knob 12 is arranged at the end of the clamping head 3 away from the fixing member 2 through threaded connection at the position opposite to the clamping pad 7.
[0017] Combined with Figures 1-4 As shown in the figure, during the use process, a cylinder 6 is arranged inside the extension rod 1, and the cylinder 6 is used to push the moving block 5. The movement of the moving block 5 drives the arc-shaped connecting rod 4 to push the clamping head 3 to rotate on the fixing member 2. The clamping head 3 and the clamping pad 7 are used to clamp, move or place the heat treatment sample. By driving the clamping head 3 and the clamping pad 7 to clamp the sample through the cylinder 6, compared with the conventional manually operated clamping device, the clamping force size can be preset and adjusted to meet the clamping requirements of different workpiece samples, and the clamping process is more stable. The manually operated clamping device is often limited by the skills and hand strength of the operator and is difficult to maintain long-term stable clamping. Moreover, the clamping driven by the cylinder 6 can effectively reduce the labor intensity of the operator and increase the work efficiency. The control button 9 is used to operate the cylinder 6, which is simple, convenient and easy to operate.
[0018] By arranging a plurality of clamping pads 7 slidably in the two clamping heads 3 and cooperating with the spring 8 arranged between the clamping pads 7 and the clamping heads 3, when the cylinder 6 drives the clamping head 3 to use the clamping pad 7 to clamp the sample, the protruding position of the sample will squeeze the opposite clamping pad 7, causing the opposite spring 8 to compress. The clamping pad 7 opposite to the concave position of the sample will protrude relatively under the thrust of the spring 8 to fit on the sample. The plurality of clamping pads 7 arranged on the clamping head 3 will form a shape that fits the outer wall of the sample as a whole. Then, the positions of the plurality of clamping pads 7 are fixed through the fastening knob 12, which is convenient for clamping and using this sample, increases the contact area between the workpiece and the clamping head 3 and the clamping pad 7, reduces the stress deformation of the workpiece, and can increase the stable effect during the clamping process, prevent the workpiece from falling during the movement process, and reduce sample damage.
[0019] The clamping pad 7 is composed of a plurality of independently arranged cushion blocks 10; springs 8 are arranged between each cushion block 10 and the chuck 3. The clamping pad 7 composed of a plurality of independent cushion blocks 10 can also form a corresponding conforming shape in the vertical direction according to the shape of the sample, making the application range of this clamping device larger. When replacing samples of different shapes for heat treatment tests, only the cylinder 6 needs to be used to drive the chuck 3 to clamp the sample, and then the fastening knob 12 is used to fix the plurality of clamping pads 7 and cushion blocks 10 to obtain a clamping tool that conforms to the shape of the test sample. The operation is convenient and the fitting degree is relatively high, protecting the sample from deforming due to stress during placement, increasing the stability during the clamping process, and having a wide application range.
[0020] A plurality of groups of anti-slip lines 11 are arranged on both sides of the cushion block 10. When the fastening knob 12 is rotated to fix the plurality of clamping pads 7 together by using the fastening knob 12, the anti-slip lines 11 arranged oppositely on two adjacent cushion blocks 10 are attached together, forming a good anti-slip and fixing effect, and preventing the cushion block 10 from shifting and sliding during the clamping process of the heat test sample.
[0021] It can be understood that the present utility model is described through some embodiments. As is known to those skilled in the art, without departing from the spirit and scope of the present utility model, various changes or equivalent replacements can be made to these features and embodiments. Additionally, under the teaching of the present utility model, these features and embodiments can be modified to adapt to specific situations and materials without departing from the spirit and scope of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed herein, and all embodiments falling within the scope of the claims of this application belong to the scope protected by the present utility model.
