Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4A tensile testing machine auxiliary device includes a base 100. A load-bearing block 101 is fixedly connected to the lower side of the base 100. Four sets of feet 102 are fixedly connected to the lower side of the load-bearing block 101. Rubber pads 103 are fixedly connected to the lower side of the feet 102. By setting the load-bearing block 101, the center of gravity of the device is lowered, improving the stability of the device during use. The feet 102 and rubber pads 103 improve the stability of the device when placed. A support column 110 is fixedly connected to the upper side of the base 100. An upper plate 120 is fixedly connected to the upper side of the support column 110. An air valve is fixedly connected to the upper side of the base 100. A cylinder 130 is fixedly connected to a lower plate 140 at its telescopic end. A laser rangefinder 150 is fixedly connected to the lower side of an upper plate 120. A clamp 200 is fixedly installed on the opposite sides of the upper plate 120 and the lower plate 140. Two sets of guide rods 141 are fixedly connected to the upper side of a base 100, passing through the left and right sides of the lower plate 140 respectively. The guide rods 141 improve the stability of the lower plate 140 during its up-and-down movement, thereby improving the accuracy of subsequent testing. An elongation measuring scale 160 is connected to the front of the upper plate 120 and the lower plate 140. The elongation measuring scale 160 improves the stability of the lower plate 140 during its up-and-down movement. The accuracy of this device allows it to calculate the tensile strength of the test item not only by measuring the distance between the upper plate 120 and the lower plate 140 using the laser rangefinder 150, but also by calculating the tensile strength using the elongation measuring scale 160. The upper clamp 200 is fixed at the 0 position of the elongation measuring scale 160, while the lower clamp 200 is the movable position of the elongation measuring scale 160. The test item is fixed using the two clamps 200. Then, the cylinder 130 is activated to move the lower plate 140 downwards, which in turn moves the lower clamp 200 downwards. The lower clamp 200 moves downward to pull the object under test, and the laser rangefinder 150 measures the distance between the upper plate 120 and the lower plate 140 to calculate the tensile strength of the object under test. The two clamps 200 are set in a mirror image. By setting up the support column 110, upper plate 120, cylinder 130, lower plate 140, clamps 200, elongation measuring ruler 160, and laser rangefinder 150 in combination, the workpiece can be quickly inspected. During the inspection process, it can be used with devices such as a display screen to facilitate the staff to view the inspection results, improve the boundary of the use of this device, and increase the inspection speed.

[0026] The fixture 200 includes a housing 210. A motor 220 is fixedly connected to the right side of the housing 210. A screw 230 is fixedly connected to the transmission end of the motor 220. A clamping plate 240 is screwed to the outer side of the screw 230. A sliding groove matching the clamping plate 240 is provided on the rear side of the housing 210. When the motor 220 is started, the screw 230 is rotated. The rotation of the screw 230 causes the clamping plate 240 to move left and right. The clamping plate 240 moves to the left and closer to the housing 210 to complete the clamping of the object to be measured, improving the ease of use of the device. By setting the fixture 200, the object to be measured can be quickly fixed and released, improving the ease of use of the device. A limit rod 250 is connected to the front side of the housing 210. The left side of the limit rod 250 passes through the rear side of the clamping plate 240. By setting the limit rod 250, the stability of the clamping plate 240 during operation is improved, which indirectly improves the stability of the fixture 200 and improves the clamping efficiency of the workpiece.

[0027] Auxiliary devices 260 are bolted to the left side of clamping plate 240 and the left side wall of chassis 210. The left and right auxiliary devices 260 are mirror images of each other. The left auxiliary device 260 includes a fixing plate 261 with mounting holes for easy replacement of different auxiliary devices 260 and maintenance. The right side of fixing plate 261 has multiple through holes and multiple springs 262 are fixedly connected to it. The right side of springs 262 is fixedly connected to a locking block 263. Both springs 262 and locking blocks 263 are located inside the through holes of fixing plate 261. During use, the operator can choose to clamp and fix the test item through the two fixing plates 261, or use the elastic force generated by the deformation of springs 262 to drive the locking block 263 to fix the item. By setting springs 262 and locking blocks 263, the efficiency of this device in dealing with different test items is improved, and the efficiency of testing irregular items is enhanced. The fixing plate 261 allows the operator to switch between different auxiliary devices 260.
