Description

Technical Field

[0001] The invention relates to an adjustable conical shell hardness inspection and positioning tool. Background Art

[0002] Some metal conical shells need to withstand chemical energy impact during work. Not only do they need to measure the hardness parameters, but they also need to directly link their hardness values ​​with the effect of withstanding chemical energy impact during the test. Therefore, the product cannot be scrapped after the hardness inspection, and it needs to be used for assembly and testing later. The position where the testing equipment is used to check the hardness of the metal conical shell must be within 1-10mm from the large end face of the conical shell, so as to ensure that the product can still be used later after the hardness test, and the same positioning tool is required to be compatible with multiple types of conical shells, but there is no equipment in the prior art that meets the above requirements.

[0008] The above-mentioned adjustable conical shell hardness inspection and positioning tool, the locking piece is a first screw, and a waist-shaped hole is provided on one side of the adjustment seat. The first screw passes through the washer and the waist-shaped hole in sequence to lock the adjustment seat on the fixed seat.

[0009] The above-mentioned adjustable conical shell hardness inspection and positioning tool has a mounting groove on the other side of the adjustment seat, and the lower matching part of the cone is placed in the mounting groove. Pin holes are provided on both sides of the groove wall of the mounting groove. The pin passes through the pin hole and the lower matching part of the cone to position the lower matching part of the cone.

[0010] The above-mentioned adjustable conical shell hardness inspection and positioning tool has a second screw at the bottom of the mounting groove, and the adjustment seat and the matching part at the lower part of the cone are connected and fixed by the second screw.

[0011] The above-mentioned adjustable conical shell hardness inspection and positioning tool has a knurled high-head screw on the side of the adjustment seat for tightening the fixing seat from the side.

[0012] The beneficial effects of the present invention are as follows: the present invention has a simple structure and is easy to operate, and can be used to measure the hardness of a series of conical shells. The conical shells whose hardness has been measured can be directly used in subsequent production assembly and testing, thus avoiding waste, and obtaining direct test data, which meets the requirements of lean production and cost reduction of manufacturing enterprises.

[0017] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0018] like Figure 1-Figure 4 As shown, an adjustable conical shell hardness inspection and positioning tool includes a fixing seat 5, an adjusting seat 1 and a cone 8.

[0019] A cylinder 51 is protruded from the bottom of the fixing seat 5, and the cylinder 51 is inserted into the mounting hole of the detection device. The axis of the mounting hole of the detection device coincides with the center line of the indenter of the detection device for checking hardness.

[0020] The adjusting seat 1 can be slidably mounted on the fixing seat 5 and locked by a locking member. The lower matching part of the cone 8 is fixedly mounted on the adjusting seat 1 , and the workpiece 9 to be measured is sleeved on the cone 8 .

[0021] A dovetail groove 11 is provided in the middle of the bottom surface of the adjusting seat 1 , and trapezoidal rails 52 are provided on both sides of the top surface of the fixing seat 5 . The dovetail groove 11 of the adjusting seat 1 is sleeved on the trapezoidal rails 52 of the fixing seat 5 .

[0022] The locking member is a first screw 3 . A waist-shaped hole 13 is provided on one side of the adjustment seat 1 . The first screw 3 passes through the washer 2 and the waist-shaped hole 13 in sequence to lock the adjustment seat 1 on the fixing seat 5 .

[0023] A mounting groove 12 is provided on the other side of the adjustment seat 1, and the lower matching part of the cone 8 is placed in the mounting groove 12. Pin holes 14 are provided on both sides of the groove wall of the mounting groove 12. The pin 7 passes through the pin hole 14 and the lower matching part of the cone 8 to position the lower matching part of the cone 8.

[0024] A second screw 6 is provided at the bottom of the mounting groove 12 , and the adjustment seat 1 and the matching part at the lower part of the cone 8 are connected and fixed by the second screw 6 .

[0025] The side of the adjusting seat 1 is provided with a knurled high head screw 4 for tightening the fixing seat 5 from the side.

[0026] The specific working mode of the present invention is:

[0027] First, insert the bottom cylinder 51 of the fixed seat 5 into the mounting hole of the testing equipment, and the axis of the mounting hole coincides with the center line of the indenter of the testing equipment for checking hardness. Then, put the dovetail groove 11 of the adjustment seat 1 on the trapezoidal rail 52 of the fixed seat 5, insert the lower matching part of the cone 8 into the mounting groove 12 of the adjustment seat 1, and use the pin 7 for positioning and the second screw 6 for connection and fixing.

[0028] Put the conical shell (i.e. the workpiece to be tested 9) on the cone 8, move the position of the adjustment seat 1 so that the position of the pressure head for checking the hardness is within the range of 1-10mm of the large end surface of the conical shell, use the washer 2 and the first screw 3 to lock the adjustment seat 1 and the fixed seat 5, and tighten the side of the knurled high head screw 4.

[0029] Since the nut head hole for installing the first screw 3 is a waist-shaped hole, when replacing a conical shell of different size but the same taper for inspection, it is only necessary to loosen the first screw 3 and the knurled high head screw 4, move the adjustment seat 1 to the required position and then tighten it; if the taper of the conical shell is different, just replace the cone 8.
