Abstract
Description
Technical Field
[0001] This invention relates to the technical field of hardness testing equipment for castings and forgings, specifically to a device for testing the hardness of processed castings and forgings. Background Technology
[0002] Castings and forgings play an important role in machine tool manufacturing, automobile manufacturing, shipbuilding, power plants, weaponry, steel manufacturing and other fields. As very important components, their processes and processing are relatively complex. The usual process is to melt and cast ingots, then forge or remelt and cast them into shape, and finally obtain the required shape, size and technical requirements through a high-frequency heating machine to meet the needs of different scenarios.
[0003] When testing the hardness of castings and forgings, due to the diverse shapes of these parts, such as valve components (model V-2021, ductile iron, arc-shaped sealing surface design), pressure needs to be applied to the outer wall of the casting or forging during hardness testing. Due to the increased pressure and the imbalance of pressure points, the casting or forging may break off. To address these issues, the following solutions are proposed. Summary of the Invention
[0004] To solve the above-mentioned technical problems, the present invention provides a hardness testing device for castings and forgings, including a housing, a slide rail fixedly connected to the side wall of the housing, a movable frame slidably connected to the inner wall of the slide rail, a screen fixedly connected to the side wall of the housing, and a probe fixedly connected to the bottom of the movable frame, and further comprising:
[0005] The adapting mechanism is rotatably connected to the inner wall of the chassis and is used to clamp the arc-shaped castings and forgings.
[0006] The orientation mechanism is fixedly connected to the inner wall of the chassis. After the adaptation mechanism completes clamping, the orientation mechanism will block the adaptation mechanism.
[0007] The snap-fit mechanism is fixedly connected to the top of the chassis and is used to clamp and restrict the outer wall of the casting or forging.
[0008] Before use, the casting or forging is pressed into the inner wall of the adapting mechanism. Then, the adapting mechanism is rotated to force the snapping mechanism to extend inward and fit against the outer wall of the casting or forging. The adapting mechanism is then rotated again until the orientation mechanism completes the snapping.
[0009] Preferably, the adapting mechanism includes:
[0010] Auxiliary components are rotatably connected to the inner wall of the through-hole in the chassis via rotating parts;
[0011] The rotating component includes a rotating cylinder rotatably connected to the inner wall of the through hole of the chassis, and two limiting rings are fixedly connected to the outer wall of the rotating cylinder;
[0012] The pressure-bearing component is fixedly connected to the inner wall of the rotating cylinder via a flow-through component;
[0013] The flow component includes a cavity at the bottom of the rotating cylinder, and several grooves are provided on the inner wall of the rotating cylinder. A pressure rod is slidably connected to the inner wall of the grooves.
[0014] Before use, the cavity and the inside of the slide groove need to be filled with hydraulic oil, and it is necessary to ensure that there is no air residue inside. When it is necessary to clamp the casting or forging, the casting or forging is first pressed on the top of the pressure rod. Multiple pressure rods will adapt to the changes in the outer wall of the casting or forging.
[0015] Preferably, the orientation mechanism includes:
[0016] The fixing component is fixedly connected to the inner wall of the chassis by positioning parts;
[0017] The positioning component includes an L-shaped rod fixedly connected to the inner wall of the chassis, and a round tube fixedly connected to the other end of the L-shaped rod;
[0018] The obstruction component is fixedly connected to the top of the round tube by a limiting member;
[0019] The limiting component includes a disc fixedly connected to the end of the round tube away from the L-shaped rod, and a flow hole is provided on the outer wall of the disc.
[0020] During the rotation of the rotating cylinder, the disc and the L-shaped rod remain stationary. This results in the flow hole being completely misaligned with the slide groove after the rotating cylinder has fully rotated.
[0021] Preferably, the latching mechanism includes:
[0022] The pushing component is fixedly connected to the inner wall of the rotating cylinder via a pressure component;
[0023] The pressure component includes several positioning blocks that are fixedly connected to the inner wall of the rotating cylinder;
[0024] The limiting component is fixedly connected to the top of the chassis via a barrier.
[0025] The obstruction includes a fixed bracket fixedly connected to the top of the chassis, and a ring fixedly connected to the other end of the fixed bracket. The outer wall of the ring is rotatably connected to the inner wall of the rotating cylinder, and an outer moving rod is rotatably connected to the top of the ring.
[0026] As the rotating cylinder rotates, the pushing component forces the limiting component to rotate outward and covers the top of the casting or forging.
[0027] Preferably, the auxiliary component includes a partition plate 1 fixedly connected to the bottom of the rotating cylinder, and the inner wall of the through hole of the partition plate 1 is rotatably connected to the outer wall of the hollow tube.
[0028] Before the rotating cylinder rotates, it is necessary to ensure that the castings and forgings are in a horizontal position and located at the center of the inner wall of the rotating cylinder.
[0029] Preferably, the pressure-bearing component includes a spring fixedly connected to the bottom of the pressure-bearing rod, with the end of the spring away from the pressure-bearing rod fixedly connected to the inner wall of the groove;
[0030] When the compression rod moves under pressure, the spring will deform under pressure and accumulate potential energy.
[0031] Preferably, the fixing component includes a hollow tube formed in the outer wall of the circular tube;
[0032] The hollow tube ensures that the flow hole at the center of the disc is in a state of flow with the other flow holes.
[0033] Preferably, the obstruction component includes a snap-fit spring piece fixedly connected to an outer wall of the disk, and a slot block fixedly connected to the inner wall of the cavity;
[0034] During equipment use, as the rotating drum rotates, it will cause the slot block to move closer to the snap-fit spring. As the pressure increases, the snap-fit spring will lift upward and eventually enter the inner wall of the slot block to complete the snap-fit restriction.
[0035] Preferably, the pushing component includes a pushing rod rotatably connected to the outer wall of the positioning block, with one end of the pushing rod away from the positioning block rotatably connected to the inner wall of the outer moving rod;
[0036] As the rotating cylinder rotates, it pushes the push rod, which in turn forces the outer moving rod to rotate inward around the connection point.
[0037] Preferably, the limiting component includes an arc-shaped rotating rod rotatably connected to the inner wall of the outer moving rod, and a torsion spring is fixedly connected to the inner wall of the arc-shaped rotating rod;
[0038] In this configuration, the torsion spring forces the arc-shaped rotating rod to open outwards under normal conditions. When the outer moving rod rotates inwards, the end of the arc-shaped rotating rod will contact the outer wall of the casting or forging. As the outer moving rod rotates, the arc-shaped rotating rod will rotate around the torsion spring.
[0039] The present invention has the following beneficial effects:
[0040] (1) This invention addresses the issue of arc-shaped cast and forged parts easily shattering under pressure. The worker holds the cast and forged part and places it at the center of the rotating cylinder, then presses down on the top of the part. At this time, multiple pressure rods will adapt to the change in the outer wall of the cast and forged part, causing them to slide. Hydraulic oil inside the groove will enter the cavity and force the remaining pressure rods to move upwards. The worker then twists the rotating cylinder. During this process, the L-shaped rod restricts the flow hole through the round tube, keeping the flow hole stationary. When the rotating cylinder rotates to its maximum angle, the flow hole and the groove will be misaligned. Figure 4 The state of G in the middle becomes Figure 5 In state F, because the flow hole and the chute are blocked, the liquid inside the chute cannot flow, and the sliding of all the pressure rods is restricted. Through the application of the above components, when the equipment faces the curved outer wall of the casting or forging, multiple pressure rods can adapt to the outer wall of the casting or forging, preventing the phenomenon of flying off due to the instability of the contact point during pressure testing because the outer wall of the casting or forging is curved.
[0041] (2) This invention utilizes the rotational characteristics of the rotating cylinder described above, and includes a latching mechanism inside the equipment. When the rotating cylinder rotates, it drives the positioning block to rotate synchronously. The positioning block, through a push rod, pushes the outward-moving rod to rotate around the connection point. Figure 9 The R state changes to the H state and covers the top outer wall of the casting or forging. Through the application of the above components, it is prevented that when the probe squeezes the outer wall of one end of the casting or forging, the other end of the casting or forging will be tilted due to pressure, which would cause excessive differences in the data collected by the probe.
[0042] (3) This invention utilizes the outward rotation characteristic of the above-mentioned external moving rod and sets an arc-shaped rotating rod inside the equipment. Under normal conditions, the torsion spring will force the arc-shaped rotating rod to open outward. When the external moving rod rotates inward, the end of the arc-shaped rotating rod will contact the outer wall of the convex casting and forging. As the external moving rod rotates, the arc-shaped rotating rod will rotate around the torsion spring and cover the outer wall of the casting and forging. In addition, as the rotating cylinder rotates, the rotating cylinder will drive the slot block to move closer to the snap-fit spring. As the extrusion pressure increases, the snap-fit spring will lift up and finally enter the inner wall of the slot block to complete the snap-fit restriction. Through the application of the above components, it can adapt to castings and forgings with different external curvatures.
[0043] (4) The present invention utilizes the characteristics of the outer moving rod and the torsion spring to restrict the outer wall of the casting and forging. When the rotating cylinder rotates to half an angle, the outer moving rod will cover the top of the casting and forging. At this time, the operator can release the pressure on the casting and forging. The spring will release potential energy and push the casting and forging to move upward, so that the top outer wall of the casting and forging is in contact with the bottom of the outer moving rod and the torsion spring. Since multiple outer moving rods and torsion springs are located on the same horizontal plane, when the equipment completes the clamping of the casting and forging, the casting and forging will be in a horizontal state with the plane of the machine box.

[0057] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0058] Example 1, please refer to Figure 1 - Figure 3 This invention relates to a device for testing the hardness of castings and forgings, comprising a housing 13, a slide rail 14 fixedly connected to the side wall of the housing 13, a movable frame 15 slidably connected to the inner wall of the slide rail 14, a screen 16 fixedly connected to the side wall of the housing 13, and a probe 17 fixedly connected to the bottom of the movable frame 15, and further comprising:
[0059] The adapting mechanism 1 is rotatably connected to the inner wall of the housing 13 and is used to clamp the arc-shaped casting and forging.
[0060] Orientation mechanism 2 is fixedly connected to the inner wall of the chassis 13. After the adaptation mechanism 1 completes clamping, the orientation mechanism 2 will block the adaptation mechanism 1.
[0061] The latching mechanism 3 is fixedly connected to the top of the housing 13 and is used to clamp and restrict the outer wall of the casting and forging.
[0062] Before use, the casting or forging is pressed into the inner wall of the adapting mechanism 1, and then the adapting mechanism 1 is rotated to force the snapping mechanism 3 to extend inward and fit against the outer wall of the casting or forging. Then the adapting mechanism 1 is rotated again until the directional mechanism 2 completes the snapping.
[0063] Adaptive mechanism 1 includes:
[0064] Auxiliary component 11 is rotatably connected to the inner wall of the through hole of the chassis 13 via a rotating component;
[0065] The rotating component includes a rotating cylinder 111 rotatably connected to the inner wall of the through hole of the housing 13, and two limiting rings 112 are fixedly connected to the outer wall of the rotating cylinder 111.
[0066] The pressure-bearing component 12 is fixedly connected to the inner wall of the rotating cylinder 111 via a flow-through component;
[0067] The flow component includes a cavity 121 opened at the bottom of the rotating cylinder 111, and a plurality of sliding grooves 122 are opened on the inner wall of the rotating cylinder 111. A pressure rod 123 is slidably connected to the inner wall of the plurality of sliding grooves 122.
[0068] Before use, the cavity 121 and the slide groove 122 must be filled with hydraulic oil and it must be ensured that there is no air residue inside. When it is necessary to clamp the casting or forging, the casting or forging is first pressed on the top of the pressure rod 123. The multiple pressure rods 123 will slide adaptively according to the changes in the outer wall of the casting or forging.
[0069] Targeted agency 2 includes:
[0070] The fixing component 21 is fixedly connected to the inner wall of the chassis 13 by a positioning member;
[0071] The positioning component includes an L-shaped rod 211 fixedly connected to the inner wall of the chassis 13, and a round tube 212 fixedly connected to the other end of the L-shaped rod 211.
[0072] Obstruction component 22 is fixedly connected to the top of the circular tube 212 by a limiting member;
[0073] The limiting component includes a disc 221 fixedly connected to one end of the round tube 212 away from the L-shaped rod 211, and a flow hole 222 is provided on the outer wall of the disc 221.
[0074] Before use, the machine casing 13 is fixed in the required position. Then, the operator holds the casting and forging and places it in the center of the rotating cylinder 111. Then, the top of the casting and forging is pressed down. At this time, multiple pressure rods 123 will slide adaptively according to the change of the outer wall of the casting and forging. The hydraulic oil inside the slide groove 122 will enter the cavity 121 and force the remaining pressure rods 123 to move upward. Then, the operator twists the rotating cylinder 111. During this process, the L-shaped rod 211 restricts the flow hole 222 through the round tube 212, so that the flow hole 222 is in a stationary state.
[0075] The latching mechanism 3 includes:
[0076] Pushing component 31 is fixedly connected to the inner wall of rotating cylinder 111 via a pressure component;
[0077] The pressure component includes several positioning blocks 311 that are fixedly connected to the inner wall of the rotating cylinder 111;
[0078] The limiting component 32 is fixedly connected to the top of the chassis 13 by means of a barrier;
[0079] The obstruction includes a fixed bracket 321 fixedly connected to the top of the chassis 13, and a ring 322 fixedly connected to the other end of the fixed bracket 321. The outer wall of the ring 322 is rotatably connected to the inner wall of the rotating cylinder 111, and an outer moving rod 323 is rotatably connected to the top of the ring 322.
[0080] When the rotating cylinder 111 rotates, the pushing component 31 will force the limiting component 32 to rotate outward and cover the top of the casting or forging.
[0081] Example 2, please refer to Figure 6 - Figure 10 The present invention is a hardness testing device for casting and forging parts. Based on Example 1, the auxiliary component 11 includes a partition plate 113 fixedly connected to the bottom of the rotating cylinder 111, and the inner wall of the through hole of the partition plate 113 is rotatably connected to the outer wall of the hollow tube 213.
[0082] When the rotating cylinder 111 rotates to its maximum angle, the flow hole 222 and the slide groove 122 will be misaligned. Figure 4 The state of G in the middle becomes Figure 5 In state F, since the flow hole 222 and the slide groove 122 are blocked, the liquid inside the slide groove 122 cannot flow, and the sliding of all the pressure rods 123 is restricted. Through the application of the above components, when the equipment faces the curved outer wall of the casting or forging, the multiple pressure rods 123 can adapt to the outer wall of the casting or forging, preventing the phenomenon of flying off due to the instability of the contact point during pressure testing because the outer wall of the casting or forging is curved.
[0083] The pressure-bearing component 12 includes a spring 124 fixedly connected to the bottom of the pressure-bearing rod 123, and the end of the spring 124 away from the pressure-bearing rod 123 is fixedly connected to the inner wall of the slide groove 122.
[0084] Utilizing the rotational characteristic of the rotating cylinder 111, a latching mechanism 3 is installed inside the equipment. When the rotating cylinder 111 rotates, it drives the positioning block 311 to rotate synchronously. The positioning block 311, in turn, pushes the outward moving rod 323 via the push rod 312 to rotate around the connection point. Figure 9The R state changes to the H state and covers the top outer wall of the casting or forging. Through the application of the above components, it is prevented that when the probe 17 presses the outer wall of one end of the casting or forging, the other end of the casting or forging will be tilted due to pressure, which would cause excessive differences in the data collected by the probe 17.
[0085] The fixing component 21 includes a hollow tube 213 formed on the outer wall of the circular tube 212;
[0086] Among them, the hollow tube 213 ensures that the flow hole 222 at the center of the disk 221 is in a state of flow with the other flow holes 222.
[0087] The obstruction component 22 includes a snap-fit spring piece 223 fixedly connected to the outer wall of the disk 221, and a slot block 224 fixedly connected to the inner wall of the cavity 121.
[0088] When the equipment is in use, as the rotating cylinder 111 rotates, it will drive the slot block 224 to move closer to the snap-fit spring 223. As the pressure increases, the snap-fit spring 223 will lift up and eventually enter the inner wall of the slot block 224 to complete the snap-fit restriction.
[0089] The pushing assembly 31 includes a pushing rod 312 rotatably connected to the outer wall of the positioning block 311, and one end of the pushing rod 312 away from the positioning block 311 is rotatably connected to the inner wall of the outer moving rod 323;
[0090] Utilizing the characteristics of the outer displacement rod 323 and torsion spring 325 restricting the outer wall of the casting and forging, when the rotating cylinder 111 rotates to half an angle, the outer displacement rod 323 will cover the top of the casting and forging. At this time, the operator can release the pressure on the casting and forging, and the spring 124 will release potential energy and push the casting and forging to move upward, so that the top outer wall of the casting and forging is in contact with the bottom of the outer displacement rod 323 and torsion spring 325. Since multiple outer displacement rods 323 and torsion spring 325 are located on the same horizontal plane, when the equipment completes the clamping of the casting and forging, the casting and forging will be in a horizontal state with the plane of the machine box 13.
[0091] The limiting component 32 includes an arc-shaped rotating rod 324 rotatably connected to the inner wall of the outer moving rod 323, and a torsion spring 325 is fixedly connected to the inner wall of the arc-shaped rotating rod 324;
[0092] Utilizing the outward rotation characteristic of the aforementioned outward-moving rod 323, an arc-shaped rotating rod 324 is installed inside the equipment. Under normal conditions, the torsion spring 325 forces the arc-shaped rotating rod 324 to open outward. When the outward-moving rod 323 rotates inward, the end of the arc-shaped rotating rod 324 contacts the outer wall of the convex casting or forging. As the outward-moving rod 323 rotates, the arc-shaped rotating rod 324 rotates around the torsion spring 325 and covers the outer wall of the casting or forging. In addition, as the rotating cylinder 111 rotates, it drives the slot block 224 to move closer to the snap-fit spring 223. As the extrusion pressure increases, the snap-fit spring 223 lifts upward and eventually enters the inner wall of the slot block 224, completing the snap-fit restriction. Through the application of the above components, castings and forgings with different external curvatures can be accommodated.
[0093] A specific application of this embodiment is as follows: Before use, the chassis 13 is fixed in the required position. Then, the operator holds the forged casting and places it in the center of the rotating cylinder 111, and then presses down on the top of the forged casting. At this time, multiple pressure rods 123 will adapt to the change of the outer wall of the forged casting and slide accordingly. The hydraulic oil inside the groove 122 will enter the cavity 121 and force the remaining pressure rods 123 to move upward. Then, the operator twists the rotating cylinder 111. During this process, the L-shaped rod 211 restricts the flow hole 222 through the round tube 212, so that the flow hole 222 is in a stationary state. When the rotating cylinder 111 rotates to the maximum angle, the flow hole 222 and the groove 122 will be misaligned. Figure 4 The state of G in the middle becomes Figure 5 In state F, since the flow hole 222 and the slide groove 122 are blocked, the liquid inside the slide groove 122 cannot flow, and the sliding of all the pressure rods 123 is restricted. Through the application of the above components, when the equipment faces the curved outer wall of the casting or forging, the multiple pressure rods 123 can adapt to the outer wall of the casting or forging, preventing the phenomenon of flying off due to the instability of the contact point during pressure testing because the outer wall of the casting or forging is curved.
[0094] Taking advantage of the rotational characteristics of the rotating cylinder 111, a latching mechanism 3 is installed inside the equipment. When the rotating cylinder 111 rotates, it drives the positioning block 311 to rotate synchronously. The positioning block 311, in turn, pushes the outward moving rod 323 to rotate around the connection point via the push rod 312. Figure 9 The R state changes to the H state and covers the top outer wall of the casting or forging. Through the application of the above components, it is prevented that when the probe 17 presses the outer wall of one end of the casting or forging, the other end of the casting or forging will be tilted due to pressure, which would cause excessive differences in the data collected by the probe 17.
[0095] Utilizing the outward rotation characteristic of the aforementioned outward-moving rod 323, an arc-shaped rotating rod 324 is installed inside the equipment. Under normal conditions, the torsion spring 325 forces the arc-shaped rotating rod 324 to open outward. When the outward-moving rod 323 rotates inward, the end of the arc-shaped rotating rod 324 contacts the outer wall of the convex casting or forging. As the outward-moving rod 323 rotates, the arc-shaped rotating rod 324 rotates around the torsion spring 325 and covers the outer wall of the casting or forging. In addition, as the rotating cylinder 111 rotates, it drives the slot block 224 to move closer to the snap-fit spring 223. As the extrusion pressure increases, the snap-fit spring 223 will lift upward and eventually enter the inner wall of the slot block 224 to complete the snap-fit restriction. Through the application of the above components, castings and forgings with different external curvatures can be adapted.
[0096] Utilizing the characteristics of the outer displacement rod 323 and the torsion spring 325 restricting the outer wall of the casting and forging, when the rotating cylinder 111 rotates to half an angle, the outer displacement rod 323 will cover the top of the casting and forging. At this time, the operator can release the pressure on the casting and forging, and the spring 124 will release potential energy and push the casting and forging to move upward, so that the top outer wall of the casting and forging is in contact with the bottom of the outer displacement rod 323 and the torsion spring 325. Since multiple outer displacement rods 323 and torsion springs 325 are located on the same horizontal plane, when the equipment completes the clamping of the casting and forging, the casting and forging will be in a horizontal state with the plane of the machine box 13.
