Description

Technical Field

[0001] This application relates to the technical field of cast steel detection, and particularly to a strength detection device for cast steel products. Background Art

[0002] Cast steel parts refer to parts made of cast steel, which are similar in properties to cast iron but have better strength than cast iron. After the production of cast steel is completed, quality inspection is usually required, and quality inspection generally includes categories such as tensile strength, compressive strength, plasticity, and hardness.

[0003] When performing compressive strength detection on long strip-shaped cast steel products, the cast steel products to be detected are usually set up overhead, and then a downward pressing mechanism is combined to press the middle of the product to determine the compressive strength of the product. However, during the above detection process, the product may break, and when the product breaks, a relatively violent oscillation will occur, thus affecting the clamping components of the product and causing damage to the clamping components. Summary of the Invention

[0004] This application provides a strength detection device for cast steel products, which solves the technical problem that during the compressive strength detection of long strip-shaped cast steel products in the prior art, the product may break, and when the product breaks, a relatively violent oscillation will occur, thus affecting the clamping components of the product and causing damage to the clamping components. It realizes that at the moment when the product breaks, the device disengages from the contact with the product, thereby avoiding the oscillation of the workpiece breakage from affecting the device.

[0005] This application provides a strength detection device for cast steel products, including a detection platform, and the following are arranged on the detection platform:

[0007] The separable fixing mechanism includes a first support component and a second support component, the first support component and the second support component are arranged at intervals, and both ends of the workpiece to be detected are respectively placed on the first support component and the second support component;

[0008] The first support component and the second support component have the same structure, and both include a sliding groove, the sliding groove is perpendicular to the connection line of the first support component and the second support component, a first sliding seat and a second sliding seat are slidably arranged in the sliding groove, first electromagnetic plates and second electromagnetic plates are respectively arranged on the opposite surfaces of the first sliding seat and the second sliding seat, the first electromagnetic plate is installed on the first sliding seat, the second electromagnetic plate is installed on the second sliding seat, and electromagnets are arranged in the first electromagnetic plate and the second electromagnetic plate.

[0011] At the moment when the current direction of the electromagnet in the first electromagnetic plate is switched, the first spring releases the stored potential energy, pushing the first sliding seat and the second sliding seat apart.

[0012] Further, a fourth electromagnetic plate and a fifth electromagnetic plate are respectively provided on the opposite surfaces of the first sliding seat and the second sliding seat. The fourth electromagnetic plate is installed on the first sliding seat, the fifth electromagnetic plate is installed on the second sliding seat, and a third electromagnetic plate and a sixth electromagnetic plate are respectively provided at both ends of the sliding groove;

[0014] Further, the first support assembly has two forms:

[0015] Combined form. When in the combined form, the magnetic poles of the first electromagnetic plate and the second electromagnetic plate are opposite, and there is an attraction force between them, so they are combined together. The magnetic poles of the third electromagnetic plate and the fourth electromagnetic plate are the same, and there is a repulsive force between them, so they repel the first sliding seat away from the left end of the sliding groove. The magnetic poles of the fifth electromagnetic plate and the sixth electromagnetic plate are the same, and there is a repulsive force between them, so they repel the second sliding seat away from the right end of the sliding groove, making the first sliding seat and the second sliding seat fit together;

[0016] Separation form. When in the separation form, the magnetic poles of the first electromagnetic plate and the second electromagnetic plate are the same, and there is a repulsive force between them, so they quickly separate. The magnetic poles of the third electromagnetic plate and the fourth electromagnetic plate are opposite, and there is an attraction force between them, so they attract the first sliding seat close to the left end of the sliding groove. The magnetic poles of the fifth electromagnetic plate and the sixth electromagnetic plate are opposite, and there is an attraction force between them, so they attract the second sliding seat close to the right end of the sliding groove, making the first sliding seat and the second sliding seat separate.

When the first sliding seat and the second sliding seat are attached together, the second spring is in a stretched state;

[0018] At the moment when the current direction of the electromagnet in the third electromagnetic plate is switched, the second spring releases the stored potential energy, drags the first sliding seat towards the end of the sliding groove, and further separates the first sliding seat and the second sliding seat.

When the first sliding seat and the second sliding seat are attached together, the third spring is in a stretched state;

[0020] At the moment when the current direction of the electromagnet in the fifth electromagnetic plate is switched, the third spring releases the stored potential energy, drags the second sliding seat towards the end of the sliding groove, and further separates the first sliding seat and the second sliding seat.

[0021] Further, a first bearing notch is provided at the top of the first sliding seat, and a second bearing notch is provided at the top of the second sliding seat. When the first sliding seat and the second sliding seat are closely attached together, the first bearing notch and the second bearing notch are combined to form a bearing groove for receiving the end of the workpiece.

[0022] Further, a lifting support assembly is provided between the first support assembly and the second support assembly. The lifting support assembly includes a lifting groove formed in the detection platform, a first lifting cylinder is provided in the lifting groove, the output end of the first lifting cylinder is vertically upward and connected to a lifting flat plate, and the lifting flat plate matches the size of the lifting groove.

[0023] Further, when the output end of the first lifting cylinder is in a retracted state, the lifting flat plate is embedded in the lifting groove;

[0024] When the output end of the first lifting cylinder is fully extended, the lifting flat plate moves to be flush with the first sliding seat. Thus, when the workpiece is placed on the lifting flat plate, the end of the workpiece faces the first bearing notch and the second bearing notch, so as to facilitate the first support assembly to clamp the workpiece;

[0025] After the workpiece is clamped by the first support assembly, the lifting support assembly resets to avoid affecting the operation of the pressing mechanism.

[0026] The technical solution provided by this application has at least the following technical effects or advantages:

[0027] 1. Since a split fixing mechanism is adopted, when the first sliding seat and the second sliding seat in the split fixing mechanism are combined, they can carry and clamp the workpiece. The first sliding seat and the second sliding seat are magnetically attracted together. At the moment when the workpiece breaks, the magnetic attraction of the electromagnet in the first sliding seat changes, thereby pushing the first sliding seat and the second sliding seat to separate and break away from the contact with the workpiece, avoiding the oscillation when the workpiece breaks from affecting the equipment.

[0028] 2. Since the first spring, the second spring and the third spring are adopted, when the first sliding seat and the second sliding seat are attached together, the first spring is compressed, and the second spring and the third spring are stretched, so as to have more potential energy. At the moment when the workpiece breaks, the current directions of the magnets in the first sliding seat, the third electromagnetic plate and the fifth electromagnetic plate are switched, so that the separation speed of the first sliding seat and the second sliding seat is accelerated, avoiding the oscillation when the workpiece breaks from affecting the equipment.

[0045] The embodiments of the present application disclose a strength detection device for cast steel products. Since the split fixing mechanism 2 is adopted, when the first sliding seat 212 and the second sliding seat 213 in the split fixing mechanism 2 are combined together, they can carry and clamp the workpiece, and the first sliding seat 212 and the second sliding seat 213 are attracted together by magnetic force. At the moment when the workpiece breaks, the magnetic attraction of the electromagnet in the first sliding seat 212 changes, thereby pushing the first sliding seat 212 and the second sliding seat 213 to separate and break away from the contact with the workpiece, avoiding the oscillation when the workpiece breaks from affecting the device.

[0046] In order to better understand the above technical solution, the above technical solution will be described in detail below in combination with the specification drawings and specific embodiments.

[0047] Embodiment 1

[0048] Refer to Figures 1 to 8, a strength detection device for a cast steel product provided by the present invention includes a detection platform 1, and a separable fixing mechanism 2 is arranged on the detection platform 1. The separable fixing mechanism 2 is used for overhead supporting and fixing the workpiece to be detected. The separable fixing mechanism 2 includes a first support component 21 and a second support component 22. The first support component 21 and the second support component 22 are arranged at intervals, and both ends of the workpiece to be detected are respectively placed on the first support component 21 and the second support component 22.

[0049] It should be noted that with reference to Figures 4 to 8 , in this embodiment, the structures of the first support component 21 and the second support component 22 are the same, and both include a sliding groove 211. The sliding groove 211 is perpendicular to the connection line of the first support component 21 and the second support component 22. A first sliding seat 212 and a second sliding seat 213 are slidably arranged in the sliding groove 211. First electromagnetic plates 216 and second electromagnetic plates 217 are respectively arranged on the opposite surfaces of the first sliding seat 212 and the second sliding seat 213. The first electromagnetic plate 216 is installed on the first sliding seat 212, and the second electromagnetic plate 217 is installed on the second sliding seat 213. Electromagnets are arranged in the first electromagnetic plate 216 and the second electromagnetic plate 217. The electromagnets have magnetism when energized and have different magnetic poles according to different current directions.

[0050] Specifically, with reference to Figure 5 , a first bearing notch 214 is arranged at the top of the first sliding seat 212, and a second bearing notch 215 is arranged at the top of the second sliding seat 213. When the first sliding seat 212 and the second sliding seat 213 are closely attached together, the first bearing notch 214 and the second bearing notch 215 are combined together to form a bearing groove, and the bearing groove is used for receiving the end of the workpiece.

[0051] Based on the above settings, in this embodiment, the first sliding seat 212 and the second sliding seat 213 are attracted together by magnetic force to clamp the workpiece. At the moment when the workpiece breaks, the magnetic attraction change of the electromagnet in the first sliding seat 212 pushes the first sliding seat 212 and the second sliding seat 213 to separate and break away from the contact with the workpiece, avoiding the oscillation when the workpiece breaks from affecting the device.

[0052] Furthermore, with reference to Figure 5, on the opposite surfaces of the first sliding seat 212 and the second sliding seat 213, a fourth electromagnetic plate 219 and a fifth electromagnetic plate 2110 are respectively arranged. The fourth electromagnetic plate 219 is installed on the first sliding seat 212, and the fifth electromagnetic plate 2110 is installed on the second sliding seat 213. At both ends of the sliding groove 211, a third electromagnetic plate 218 and a sixth electromagnetic plate 2111 are respectively arranged. Electromagnets are arranged inside the third electromagnetic plate 218, the fourth electromagnetic plate 219, the fifth electromagnetic plate 2110, and the sixth electromagnetic plate 2111, which are magnetic when energized and have different magnetic poles according to different current directions.

[0053] The first support assembly 21 of this embodiment has two forms:

[0054] Combined form. When in the combined form, the magnetic poles of the first electromagnetic plate 216 and the second electromagnetic plate 217 are opposite, and there is a large suction force between them, so they are combined together. The magnetic properties of the third electromagnetic plate 218 and the fourth electromagnetic plate 219 are the same, and there is a large repulsive force between them, so as to repel the first sliding seat 212 away from the left end of the sliding groove 211. The magnetic properties of the fifth electromagnetic plate 2110 and the sixth electromagnetic plate 2111 are the same, and there is a large repulsive force between them, so as to repel the second sliding seat 213 away from the right end of the sliding groove 211, making the first sliding seat 212 and the second sliding seat 213 fit together;

[0055] The combined action of the first electromagnetic plate 216, the second electromagnetic plate 217, the third electromagnetic plate 218, the fourth electromagnetic plate 219, the fifth electromagnetic plate 2110, and the sixth electromagnetic plate 2111 makes the first sliding seat 212 and the second sliding seat 213 move to the middle part of the sliding groove 211 and fit together to clamp the workpiece;

[0056] Separation form. When in the separation form, the magnetic poles of the first electromagnetic plate 216 and the second electromagnetic plate 217 are the same, and there is a large repulsive force between them, so they are quickly separated. The magnetic properties of the third electromagnetic plate 218 and the fourth electromagnetic plate 219 are opposite, and there is a large suction force between them, so as to attract the first sliding seat 212 close to the left end of the sliding groove 211. The magnetic properties of the fifth electromagnetic plate 2110 and the sixth electromagnetic plate 2111 are opposite, and there is a large suction force between them, so as to attract the second sliding seat 213 close to the right end of the sliding groove 211, making the first sliding seat 212 and the second sliding seat 213 separate;

[0057] The combined action of the first electromagnetic plate 216, the second electromagnetic plate 217, the third electromagnetic plate 218, the fourth electromagnetic plate 219, the fifth electromagnetic plate 2110 and the sixth electromagnetic plate 2111 causes the first sliding seat 212 and the second sliding seat 213 to separate quickly, so that the end of the workpiece is no longer supported by the first support assembly 21, and there is no contact between them, avoiding the oscillation of the first support assembly 21 caused by the fracture of the workpiece.

[0058] This embodiment further includes a downward pressing mechanism. The output end of the downward pressing mechanism is located above the workpiece, and the output end of the downward pressing mechanism is located above the connection line between the first support assembly 21 and the second support assembly 22. The downward pressing mechanism is used to press the workpiece. The output end of the downward pressing mechanism is connected with a pressure sensor, and the pressure sensor is used to display the pressure value. The pressure sensor is connected with a control chip, and the control chip is connected with the electromagnet controller. When the instantaneous change of the pressure detection is zero, it indicates that the workpiece breaks at this time. At this time, the control chip controls the reversal of the electromagnet current, causing the first support assembly 21 to separate.

[0059] It should be noted that when the workpiece breaks, it is no longer pressed by the downward pressing mechanism. Therefore, the pressure applied by the downward pressing mechanism cannot be transmitted to the first support assembly 21. Therefore, the separation action of the first support assembly 21 can be carried out smoothly.

[0060] In this embodiment, by setting the split fixing mechanism 2, when the first sliding seat 212 and the second sliding seat 213 in the split fixing mechanism 2 are combined together, they can carry and clamp the workpiece, and the first sliding seat 212 and the second sliding seat 213 are attracted together by magnetic force. At the moment when the workpiece breaks, the magnetic attraction of the electromagnet in the first sliding seat 212 changes, thereby pushing the first sliding seat 212 and the second sliding seat 213 to separate, disengaging from the contact with the workpiece, and avoiding the oscillation when the workpiece breaks from affecting the equipment.

[0061] Embodiment Two

[0062] Refer to Figures 1 to 8 On the basis of Embodiment One, a first inserting rod 2112 is arranged on the first sliding seat 212, and a first inserting hole 2113 corresponding to the first inserting rod 2112 is arranged on the second sliding seat 213. A first spring 2114 is sleeved outside the first inserting rod 2112.

[0063] When the first sliding seat 212 and the second sliding seat 213 are attached together, the first inserting rod 2112 is inserted into the first inserting hole 2113, compressing the first spring 2114 so that the first spring 2114 stores potential energy;

[0064] At the moment when the current direction of the electromagnet in the first electromagnetic plate 216 is switched, the first spring 2114 releases the stored potential energy, pushing the first sliding seat 212 and the second sliding seat 213 apart.

[0065] Similarly, referring to Figures 6 to 8 , a second jack 2115 is provided at the left end of the sliding groove 211. A second plug rod 2116 corresponding to the second jack 2115 is provided on the first sliding seat 212. A second spring 2117 is provided on the second plug rod 2116. Both ends of the second spring 2117 are connected to the end of the sliding groove 211 and the first sliding seat 212 respectively. When the first sliding seat 212 and the second sliding seat 213 are attached together, the second spring 2117 is in a stretched state;

[0066] At the moment when the current direction of the electromagnet in the third electromagnetic plate 218 is switched, the second spring 2117 releases the stored potential energy, dragging the first sliding seat 212 towards the end of the sliding groove 211, and further separating the first sliding seat 212 and the second sliding seat 213.

[0067] Furthermore, a third jack 2118 is provided at the right end of the sliding groove 211. A third plug rod 2119 corresponding to the third jack 2118 is provided on the second sliding seat 213. A third spring 2120 is provided on the third plug rod 2119. The third spring 2120 is connected to the end of the sliding groove 211 and the second sliding seat 213. When the first sliding seat 212 and the second sliding seat 213 are attached together, the third spring 2120 is in a stretched state;

[0068] At the moment when the current direction of the electromagnet in the fifth electromagnetic plate 2110 is switched, the third spring 2120 releases the stored potential energy, dragging the second sliding seat 213 towards the end of the sliding groove 211, and further separating the first sliding seat 212 and the second sliding seat 213.

[0069] In this embodiment, by providing the first spring 2114, the second spring 2117, and the third spring 2120, when the first sliding seat 212 and the second sliding seat 213 are attached together, the first spring 2114 is compressed, and the second spring 2117 and the third spring 2120 are stretched, thus having more potential energy. At the moment when the workpiece breaks, the current directions of the magnets in the first sliding seat 212, the third electromagnetic plate 218, and the fifth electromagnetic plate 2110 are switched, thereby pushing the first sliding seat 212 and the second sliding seat 213 apart, disengaging from the contact with the workpiece, and avoiding the oscillation when the workpiece breaks from affecting the equipment.

[0070] Embodiment Three

The output end of the first lifting cylinder 232 is vertically upward and connected to a lifting flat plate 233. The lifting flat plate 233 matches the size of the lifting groove 231.

[0072] It should be noted that when the output end of the first lifting cylinder 232 is in the retracted state, the lifting flat plate 233 is embedded in the lifting groove 231;

[0073] When the output end of the first lifting cylinder 232 is fully extended, the lifting flat plate 233 moves to be flush with the first sliding seat 212. Thus, when a workpiece is placed on the lifting flat plate 233, the end of the workpiece is opposite to the first bearing notch 214 and the second bearing notch 215, so as to facilitate the first support assembly 21 to clamp the workpiece;

[0074] After the first support assembly 21 clamps the workpiece, the lifting support assembly 23 resets to avoid affecting the operation of the pressing mechanism.
