Description

Technical Field

[0001] The utility model relates to the technical field of metal tool strength detection, in particular to a strength testing device for promoting metal tools. Background Technique

[0002] With the development of society, metal tools are widely used in life, bringing convenience to people's work. In order to ensure the use safety of metal tools, it is necessary to detect their strength before promotion. However, in actual use, a strength testing device for promoting metal tools with a similar structure still has many defects. For example, existing metal tools lack practical strength testing equipment, resulting in potential safety hazards during the use after the promotion of metal tools. And currently, most of the few strength detection devices do not have a height adjustment mechanism, which brings inconvenience to the detection of metal tools at different heights. Therefore, it is necessary to design a strength testing device for promoting metal tools. Content of the Utility Model

[0003] The purpose of the utility model is to provide a strength testing device for promoting metal tools to solve the problems raised in the above background technique.

[0004] To achieve the above purpose, the utility model provides the following technical solution: A strength testing device for promoting metal tools, including a main body of metal tool strength detection equipment, a column, and a servo motor. A lead screw fixed to the output end of the servo motor is rotatably installed inside the column. A collar is sleeved outside the lead screw. A connecting rod is fixedly installed at the front end of the collar. The front end of the connecting rod is fixedly connected to a support plate. A hydraulic cylinder is fixedly installed on the top of the support plate. One side of the top of the main body of metal tool strength detection equipment is fixedly connected to a hydraulic oil tank. An oil delivery pipe is fixedly installed between the hydraulic cylinder and the hydraulic oil tank. A strength testing pressure plate fixed to the output end of the hydraulic cylinder is movably installed at the bottom of the support plate. A groove is opened at the top of the main body of metal tool strength detection equipment, and a pressure sensor main board is fixedly installed inside the groove.

[0005] First, the staff adjusts the device according to the height of the metal tool to be tested. The output end of the servo motor drives the lead screw to rotate, so that the collar can move up and down outside the lead screw to adjust the height. After the collar adjusts the hydraulic cylinder to a suitable height through the connecting rod and the support plate, the metal tool to be tested is placed on the top of the pressure sensor main board. Then, the hydraulic oil inside the hydraulic oil tank is transported to the inside of the hydraulic cylinder through the oil delivery pipe. The output end of the hydraulic cylinder drives the strength testing pressure plate to extend downward to squeeze the metal tool, so that the pressure sensor main board is subjected to pressure. The strength of the metal tool can be tested and analyzed through the pressure sensor main board, avoiding potential safety hazards during the use after the promotion of the metal tool under the condition of uncertain strength.

[0006] Preferably, a display panel is fixedly installed on one side of the front end of the main body of the metal tool strength detection device, and a switch is fixedly connected to the other side of the front end of the main body of the metal tool strength detection device. The detected strength of the metal tool is displayed by the display panel, and the switch can control the on / off of the device, improving the practicability of the device.

[0007] Preferably, a rubber pad is fixedly installed on the top of the pressure sensor main board, and anti-slip lines are evenly distributed on the surface of the rubber pad. The metal tool is placed on the rubber pad on the top of the pressure sensor main board and contacts the anti-slip lines on the surface of the rubber pad, making the placement of the metal tool more stable, avoiding the sliding of the metal tool on the top of the pressure sensor main board during the detection process and affecting the accuracy of the test results.

[0008] Preferably, sliding grooves are formed on both sides of the column, and threaded sliding rods fixed to the collar are slidably installed inside the sliding grooves. Nuts are rotatably installed at the ends of the threaded sliding rods away from each other. When the collar slides inside the column, the threaded sliding rods slide inside the sliding grooves, making the adjustment of the collar more stable. Then, when the collar is adjusted to the appropriate height, the nut is rotated at one end of the threaded sliding rod to fix the collar more firmly in place, enhancing the supporting force of the support plate.

[0009] Preferably, support legs are fixedly installed at the bottom of the main body of the metal tool strength detection device, and the number of support legs is four. The support legs make the placement of the main body of the metal tool strength detection device more stable, improving the stability of the device.

[0010] Preferably, suction cups are fixedly connected to the bottoms of the support legs, and the number of suction cups is four groups. The suction cups can adsorb on the platform, making the placement of the main body of the metal tool strength detection device more firm.

[0011] Preferably, a liquid inlet is formed through one side of the top of the hydraulic oil tank, and a sealing plug is slidably installed inside the liquid inlet. The staff can add hydraulic oil into the hydraulic oil tank through the liquid inlet and then seal the liquid inlet with the sealing plug, improving the operation convenience of the device.

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

[0013] 1. By providing a main body of a metal tool strength detection device, a column, a servo motor, a lead screw, and a collar, the output end of the servo motor drives the lead screw to rotate, so that the collar can move up and down to adjust the height outside the lead screw. Thus, the collar can adjust the height of the hydraulic cylinder through a connecting rod and a support plate, facilitating the strength test of metal tools at different heights and improving the adjustability of the device.

[0014] 2. By setting up a hydraulic cylinder, a hydraulic oil tank, an oil pipeline, a strength test pressing plate, and a pressure sensor main board, the hydraulic oil inside the hydraulic oil tank is transported through the oil pipeline to the inside of the hydraulic cylinder. The output end of the hydraulic cylinder drives the strength test pressing plate to extend downward to squeeze the metal tool, causing the pressure sensor main board to be pressured. The strength of the metal tool can be tested and analyzed through the pressure sensor main board, avoiding potential safety hazards when the metal tool is sold and used under uncertain strength conditions.
