[0021] The following will describe the detailed embodiments of the present utility model with reference to the drawings.
[0022] As Figures 1 to 3 shown, the present utility model provides a tooling for hardness testing of nuclear power embedded parts, which is used for the 1 / 2-section specimen A of nuclear power engineering embedded parts and the 1 / 4-section specimen B of nuclear power engineering embedded parts.
[0023] The tooling includes a base 1, a clamping assembly, and a support assembly.
[0024] As Figure 4 and 5 shown, the clamping assembly is arranged on the base 1, and clamps the square part of the 1 / 2-section sample A of the nuclear power engineering embedded part or the 1 / 4-section sample B of the nuclear power engineering embedded part.
[0025] The supporting assembly is located on the front side of the clamping assembly and includes a 1 / 2 movable dovetail supporting seat 31 and a 1 / 4 movable dovetail supporting seat 32. The 1 / 2 movable dovetail supporting seat 31 is V-shaped, and the 1 / 4 movable dovetail supporting seat 32 is arrow-shaped pointing downwards. The 1 / 2 movable dovetail supporting seat 31 is arranged on the base 1, and the curved surface part of the 1 / 2-section sample A of the nuclear power engineering embedded part is placed in the groove of the 1 / 2 movable dovetail supporting seat 31 to make the test surface of the sample reach a horizontal state. Alternatively, the 1 / 4 movable dovetail supporting seat 32 is arranged on the base 1, and the curved surface part of the 1 / 4-section sample B of the nuclear power engineering embedded part is placed in one of the grooves of the 1 / 4 movable dovetail supporting seat 32 to make the test surface of the sample reach a horizontal state.
[0026] The clamping assembly is used to clamp the square part of the 1 / 2-section sample A of the nuclear power engineering embedded part or the 1 / 4-section sample B of the nuclear power engineering embedded part. When the tooling is used for the 1 / 2-section sample A of the nuclear power engineering embedded part, the 1 / 2 movable dovetail supporting seat 31 is used and arranged on the front side of the clamping assembly to support the curved surface part of the 1 / 2-section sample A of the nuclear power engineering embedded part. When the tooling is used for the 1 / 4-section sample B of the nuclear power engineering embedded part, the 1 / 4 movable dovetail supporting seat 32 is used and arranged on the front side of the clamping assembly to support the curved surface part of the 1 / 4-section sample B of the nuclear power engineering embedded part. By supporting the curved surface part of the sample, the test surface of the sample reaches a horizontal state.
[0027] Specifically, the supporting assembly further includes a fixed dovetail supporting seat 33. The fixed dovetail supporting seat 33 is V-shaped, and the bottom end is fixed on the base 1. The 1 / 2 movable dovetail supporting seat 31 or the 1 / 4 movable dovetail supporting seat 32 is placed in the groove of the fixed dovetail supporting seat 33. The fixed dovetail supporting seat 33 is used to support the 1 / 2 movable dovetail supporting seat 31 or the 1 / 4 movable dovetail supporting seat 32 so that it can be stably arranged on the base 1, thereby stably supporting the 1 / 2-section sample A of the nuclear power engineering embedded part or the 1 / 4-section sample B of the nuclear power engineering embedded part.
[0028] The support assembly further includes a number of adjustable dovetail support seats 34. The adjustable dovetail support seats 34 are V-shaped.

Of course, if the height when the 1 / 2 movable dovetail support seat 31 or the 1 / 4 movable dovetail support seat 32 is directly placed on the fixed dovetail support seat 33 can make the test surface of the sample reach horizontal, then the adjustable dovetail support seats 34 may not be used.
[0029] The clamping assembly includes two clamping members that can move in the left-right direction. The two clamping members move towards the middle to clamp the 1 / 2 cross-section sample A of the nuclear power project embedded part or the 1 / 4 cross-section sample B of the nuclear power project embedded part. The two clamping members move towards both sides to release the 1 / 2 cross-section sample A of the nuclear power project embedded part or the 1 / 4 cross-section sample B of the nuclear power project embedded part.
[0030] Specifically, the clamping member is a clamping rod 21 arranged in the horizontal direction. The clamping rod 21 is equipped with a fixing plate 22. The fixing plate 22 is fixed on the base 1. The fixing plate 22 has an adjustment hole penetrating through from left to right. The clamping rod 21 is threadedly connected to the adjustment hole and moves left and right by rotation. In a specific embodiment, an adjustment nut 221 is embedded in the adjustment hole of the fixing plate 22. The surface of the clamping rod 21 has an external thread matching the internal thread of the adjustment nut 221, and the clamping rod 21 is threadedly connected to the adjustment nut 221.
[0031] In a preferred embodiment, a clamping block 23 is provided at the inner end of the clamping rod 21. The clamping block 23 is rotatably connected to the end of the clamping rod 21 and can rotate relative to the clamping rod 21 and move left and right therewith. The clamping rod 21 clamps the 1 / 2 cross-section sample A of the nuclear power project embedded part or the 1 / 4 cross-section sample B of the nuclear power project embedded part through the clamping block 23, so as to achieve a more stable clamping function. The bottom of the clamping block 23 contacts the base 1 to prevent the clamping rod 21 from rotating when it rotates, so as to better achieve the clamping function.
[0032] In a preferred embodiment, a hand-held nut 24 is fixed to the outer end of the clamping rod 21, and the clamping rod 21 can be more conveniently screwed through the hand-held nut 24.
[0033] The working process of the tool for hardness test of nuclear power embedded parts of the present utility model is as follows:
[0034] When used for the 1 / 2-section specimen A of the embedded parts in nuclear power engineering, according to the height of the curved surface part of the 1 / 2-section specimen A of the embedded parts in nuclear power engineering, one or more adjustable dovetail support seats 34 are placed in the grooves of the fixed dovetail support seat 33, and then the 1 / 2 movable dovetail support seat 31 is placed in the grooves of the adjustable dovetail support seat 34. Or the 1 / 2 movable dovetail support seat 31 is directly placed in the grooves of the fixed dovetail support seat 33 (that is, the adjustable dovetail support seat 34 is not placed). Then, the square part of the 1 / 2-section specimen A of the embedded parts in nuclear power engineering is placed between two clamping blocks 23, and the curved surface part is placed in the grooves of the 1 / 2 movable dovetail support seat 31, so that its test surface is in a horizontal state. Then, by holding the nut 24 and rotating the two clamping rods 21, the clamping blocks 23 are driven to move towards the middle to clamp the square part of the 1 / 2-section specimen A of the embedded parts in nuclear power engineering, so that the test surface of the 1 / 2-section specimen A of the embedded parts in nuclear power engineering remains in a horizontal state. Next, the hardness test of the 1 / 2-section specimen A of the embedded parts in nuclear power engineering can be carried out in combination with other equipment.
[0035] When used for the 1 / 4-section specimen B of the embedded parts in nuclear power engineering, according to the height of the curved surface part of the 1 / 4-section specimen B of the embedded parts in nuclear power engineering, one or more adjustable dovetail support seats 34 are placed in the grooves of the fixed dovetail support seat 33, and then the 1 / 4 movable dovetail support seat 32 is placed in the grooves of the adjustable dovetail support seat 34. Or the 1 / 4 movable dovetail support seat 32 is directly placed in the grooves of the fixed dovetail support seat 33 (that is, the adjustable dovetail support seat 34 is not placed). Then, the square part of the 1 / 4-section specimen B of the embedded parts in nuclear power engineering is placed between two clamping blocks 23, and the curved surface part is placed in one of the grooves of the 1 / 4 movable dovetail support seat 32, so that its test surface is in a horizontal state. Then, by holding the nut 24 and rotating the two clamping rods 21, the clamping blocks 23 are driven to move towards the middle to clamp the square part of the 1 / 4-section specimen B of the embedded parts in nuclear power engineering, so that the test surface of the 1 / 4-section specimen B of the embedded parts in nuclear power engineering remains in a horizontal state. Next, the hardness test of the 1 / 4-section specimen B of the embedded parts in nuclear power engineering can be carried out in combination with other equipment.
