Description

Technical Field

[0001] This utility model belongs to the field of metal material testing technology, and in particular relates to an environmental chamber support for high and low temperature tensile testing. Background Technology

[0002] Environmental chambers are widely used and are essential testing devices for high and low temperature tensile testing. During high and low temperature tensile testing, environmental chambers are used to test and determine the parameters and performance of materials and other products after changes in high, low, or constant test temperature environments. Currently, the installation method for high and low temperature tensile testing environmental chambers is usually a "front and rear push-pull type," where the environmental chamber is installed on a bracket at the rear of the tensile testing machine. During the test, the environmental chamber is pushed into the testing space of the testing machine via guide rails mounted on the bracket at the rear of the machine. After the test, the environmental chamber is pushed back along the guide rails. Although this method solves the installation and use problems of the environmental chamber, the bracket installation occupies space at the rear of the testing machine. Combined with the space of the environmental chamber itself, this makes the rear space of the testing machine very compact, causing significant inconvenience for some tests that require the use of space at the front and rear of the testing machine. Utility Model Content

[0018] This utility model provides a 16-bracket for an environmental chamber used in high and low temperature tensile testing, such as... Figure 1 As shown, the device includes a base 4 mounted on a testing machine, a vertical rod 1 mounted on the base 4, a first collar 2 and a second collar 3 fitted on the vertical rod 1, and an adjusting rod 7 connected to the end of the first collar 2 and the second collar 3 away from the vertical rod 1. The bottom of the adjusting rod 7 is a threaded section 9 and its top is a measuring scale 8. A support rod assembly is also mounted on the adjusting rod 7. The support rod assembly is located between the first collar 2 and the second collar 3. The support rod assembly is connected to the environmental chamber 16 through a rotating assembly. An anti-deviation assembly is also mounted on the support rod assembly. It should be noted that in this embodiment, the rotating component and multi-stage transmission method are used to achieve flexible adjustment of the environmental chamber 16 support, while reducing the space occupied by the testing machine. The anti-deviation component can also effectively prevent the environmental chamber 16 from shifting its position during the test. In one embodiment, the first collar 2 or the second collar 3 has a threaded hole that matches the threaded section 9; Specifically, such as Figure 1 As shown, the second collar 3 has a threaded hole that matches the threaded section 9, while the first collar 2 has a through hole through the adjusting rod 7. In one embodiment, such as Figure 1 As shown, the strut assembly includes a first strut and a second strut sleeved on the adjusting rod 7. Both the first strut and the second strut extend in the horizontal direction. The ends of the first strut and the second strut away from the adjusting rod 7 are connected to the environmental box 16 through a rotating assembly. That is, the first strut and the second strut are used to connect to the environmental box 16 while facilitating the positioning of the measuring ruler 8. In one embodiment, the rotating assembly includes a first rotating rod 13 with its two ends respectively disposed within a first support rod and a second support rod. Two parallel connecting rods are disposed on the first rotating rod 13. The end of the connecting rod away from the first rotating rod 13 passes through a second rotating rod 15. The second rotating rod 15 is connected to the environmental chamber 16. That is, the first rotating rod 13 and the second rotating rod 15 form a multi-stage conduction method. By adopting a multi-stage conduction method, the space occupied by the testing machine is reduced, while the support of the environmental chamber 16 is flexibly adjusted. Specifically, the environmental chamber 16 has protrusions on both sides of the connecting rod on the side near the rotating component. Both ends of the second rotating rod 15 are connected to the protrusions. That is, the second rotating rod 15 passes through the two connecting rods and is connected to the protrusions. The environmental chamber 16 is fixed by the threads set at the ends, and the environmental chamber 16 is rotated on the second rotating rod 15 to adjust the left and right position of the environmental chamber 16. In one embodiment, such as Figure 1 As shown, the anti-deviation assembly includes a first anti-deviation rod 12 and a second anti-deviation rod 14. The two ends of the first anti-deviation rod 12 are respectively disposed in the first support rod and the second support rod, and the two ends of the second anti-deviation rod 14 are respectively disposed in two parallel connecting rods. The first rotating rod 13 is located between the first anti-deviation rod 12 and the second anti-deviation rod 14. That is, the first anti-deviation rod 12 and the second anti-deviation rod 14 provide vertical support force to prevent the environmental box 16 from shifting. In one embodiment, a support assembly connected to the connecting rod is also provided below the second anti-deviation rod 14; Specifically, such as Figure 1 As shown, the support assembly includes a threaded sleeve 17 installed at the bottom of the connecting rod and a screw 18 sleeved in the threaded sleeve 17. That is, the screw 18 can provide further support to the environmental box 16 after the position is adjusted, thereby improving its stability. In one embodiment, fixing bolts are provided at the top corners of the base 4; like Figure 1 As shown, the base 4 is provided with a first fixing bolt 5 and a second fixing bolt 6 at the top corner, and a third fixing bolt and a fourth fixing bolt (not shown) are also provided on the other side. In one embodiment, such as Figure 1 As shown, locking bolts are also provided on the side walls of the first collar 2 and the second collar 3, that is, the first collar 2 and the second collar 3, which have been adjusted in position, are fixed to the upright 1 by the locking bolts; In one embodiment, the working principle of this device is as follows: The base 4 is installed on the testing machine by the first fixing bolt 5, the second fixing bolt 6, the third fixing bolt and the fourth fixing bolt; Loosen the bolts on the first collar 2 and the second collar 3, and adjust the first collar 2 and the second collar 3 to their approximate positions for coarse adjustment. At the same time, the environmental chamber 16 can be moved left and right by adjusting the angle of the first collar 2 and the second collar 3. Rotate the adjusting bolt to move the adjusting rod 7 up and down, while observing the position of the second ring 3 corresponding to the measuring scale 8, and then accurately adjust the environmental chamber 16 to the required position for the test. The position of the environmental chamber 16 is adjusted a second time by adjusting the angles of the first support rod 10 and the second support rod 11. The position of the environmental chamber 16 is adjusted a third time by adjusting the angle of the first rotating rod 13. The position of the environmental chamber 16 is adjusted a fourth time by adjusting the angle of the second rotating rod 15. This reduces the space occupied by the testing machine while allowing for flexible adjustment of the environmental chamber 16 support through multi-level precise adjustment. At the same time, the anti-deviation component can effectively prevent the environmental chamber 16 from shifting its position during the test.
