Description

Technical Field

[0001] The utility model relates to the technical field of engines, in particular to a blockage detection device. Background Art

[0002] This section merely provides background information related to the present disclosure and is not necessarily prior art.

[0003] There is a seam layer at the water cavity of the engine cylinder casting due to the cooperation between the sand cores. It needs to be removed so that the cooling water can circulate smoothly and cool the engine. At present, the operator uses a tool to check whether the seam is unobstructed. The manual inspection is time-consuming and labor-intensive, and the efficiency is low. In addition, due to the hidden location, it is difficult to observe with the naked eye, and the probability of missed inspection is high. Utility Model Content

[0004] The purpose of the utility model is to at least solve the problem that manual inspection of water cavity holes in engine cylinder castings is time-consuming and labor-intensive, inefficient and has a high probability of missed inspection. This purpose is achieved through the following technical solutions:

When performing detection, the product to be detected moves in the direction close to the detection piece, and the detection piece extends into the hole to be detected on the product to be detected. If the hole to be detected is blocked, the detection piece will be subjected to resistance and drive the trigger piece to move toward one end close to the sensing component, so that the trigger piece is within the sensing distance of the sensing component. At this time, the trigger piece triggers the sensing component, which means that the hole to be detected is blocked, so as to remind it to be cleaned. If the detection piece can pass through the hole to be detected without being moved by force, and the trigger piece is not within the sensing distance of the sensing component at this time, it means that the hole to be detected is not blocked. The utility model of the blockage detection device can replace manual automatic detection of the water cavity hole of the engine cylinder casting, saving time and labor, improving detection efficiency, and greatly reducing the occurrence of missed detection.

[0028] like Figure 1 to Figure 2As shown, according to an embodiment of the utility model, a blockage detection device is proposed, including a detection component and a sensing device, the detection component including a detection piece 1, the detection piece 1 is used to be set on one side of the product 2 to be detected, the sensing device includes a sensing component 3 and a triggering piece 4, the sensing component 3 is spaced apart on the side of the detection piece 1 away from the product 2 to be detected, and is spaced apart from the detection piece, the triggering piece 4 is set at one end of the detection piece 1 close to the sensing component 3, the detection piece can drive the triggering piece to move toward or away from the sensing component, the sensing component 3 is used to sense whether the triggering piece 4 is within the sensing distance of the sensing component 3, so as to perform blockage detection on the hole 21 to be detected of the product 2 to be detected.

[0029] The blockage detection device of the utility model is provided with a detection member 1 on one side of the product to be detected 2, and the detection member 1 is provided along the moving direction of the product to be detected 2, a trigger member 4 is provided at one end of the detection member 1, and a sensing component 3 is provided at intervals on the detection member 1. When performing detection, the product to be detected 2 moves in the direction close to the detection member 1, and the detection member 1 extends into the hole 21 to be detected on the product to be detected 2. If the hole 21 to be detected is blocked, the detection member 1 will be subjected to resistance and drive the trigger member 4 to move toward one end close to the sensing component 3, so that the trigger member 4 is within the sensing distance of the sensing component 3. At this time, the trigger member 4 triggers the sensing component 3, which means that the hole 21 to be detected is blocked, so as to remind the personnel to clean it. If the detection member 1 can pass through the hole 21 to be detected without being moved by force, at this time, the trigger member 4 is not within the sensing distance of the sensing component 3, which means that the hole 21 to be detected is not blocked. The blockage detection device of the utility model can replace manual automatic detection of the water cavity hole of the engine cylinder casting, saving time and labor, improving detection efficiency, and greatly reducing the occurrence of missed detection. In addition, the above-mentioned blockage detection device does not need to be connected to a separate cylinder device, saving energy and space and reducing production costs.

[0030] In some embodiments of the present utility model, the sensing device further includes an alarm 8 and a controller, the signal input end of the controller is connected to the signal output end of the sensor 30, and the signal output end of the controller is connected to the signal input end of the alarm 8. Specifically, a control box 9 is provided on the side of the first bracket away from the second bracket, the control box 9 is provided with a controller, and the alarm 8 is provided on the top of the control box 9. When the trigger 4 triggers the sensing component 3, it indicates that the hole 21 to be detected is blocked. At this time, the sensing component 3 sends a sensing signal to the controller, and the controller controls the alarm 8 to sound an alarm to remind personnel to clean it. The automation is high, labor is saved, and the detection efficiency and accuracy are improved.

[0031] In some embodiments of the present invention, the sensing component 3 includes a sensor 30 and a first bracket 31. The sensor 30 is arranged at an end of the detection member 1 away from the product to be detected 2 through the first bracket 31. The minimum distance between the sensor 30 and the trigger member 4 is less than the sensing distance, and the maximum distance between the sensor 30 and the trigger member 4 is greater than the sensing distance. Specifically, the first bracket 31 is arranged at the end of the detection member 1 away from the product 2 to be detected, and the sensor 30 is arranged at the top of the first bracket 31 and is in the same horizontal plane as the trigger member 4. When the product 2 to be detected moves toward the detection member 1, the detection member 1 extends into the hole 21 to be detected on the product 2 to be detected. If the hole 21 to be detected is blocked, the detection member 1 is subjected to resistance and will drive the trigger member 4 to move toward the end close to the sensor 30, while the sensor 30 remains stationary. The minimum distance between the sensor 30 and the trigger member 4 is less than the sensing distance. At this time, the sensor 30 can sense the trigger member 4, which is in a triggered state; and the maximum distance between the sensor 30 and the trigger member 4 is greater than the sensing distance. At this time, the sensor 30 cannot sense the trigger member 4, so that the sensor 30 has two states, namely, a triggered state and a non-triggered state. Then, the hole 21 to be detected of the product 2 to be detected can be accurately detected according to the different states of the sensor 30, which saves time and effort, improves detection efficiency, reduces missed detection, and improves detection consistency.

[0032] It should be noted that the way in which the sensor 30 senses the trigger member 4 is not limited, and can be contact sensing, that is, the sensor 30 and the trigger member 4 are in contact to achieve sensing, or non-contact sensing, that is, the sensor 30 and the trigger member 4 can achieve sensing without contact. In this embodiment, the sensor 30 is a proximity sensor, and the trigger member 4 is a magnet. By setting the proximity sensor and the magnet for use, the switching between the on state and the off state is achieved according to the position change of the magnet. In the process of the product 2 to be detected moving toward the detection member 1, the minimum distance between the magnet and the proximity sensor is less than the sensing distance of the proximity sensor. At this time, the proximity sensor can sense the magnet, showing the on state, and the proximity sensor sends the on signal to the controller, and the controller controls the alarm 8 to alarm to remind the personnel to clean it. The maximum distance between the magnet and the proximity sensor is greater than the sensing distance of the proximity sensor. At this time, the proximity sensor cannot sense the magnet, showing the off state.

[0033] It should be noted that the alarm 8 can be an audible and visual alarm or a photoelectric alarm or an audible and photoelectric alarm, etc., and the number and setting positions of the alarm 8 are not limited and can be set according to actual needs.

[0034] Since the types and sizes of the products 2 to be detected are different in actual production, the requirements for the setting distance between the sensor 30 and the trigger member 4 are different. Based on the above reasons, in some embodiments of the utility model, the sensing device also includes a sliding member, which is connected to the first bracket 31 so that the sensing component 3 can move relative to the detection component along the moving direction of the product 2 to be detected. In this embodiment, the sliding member includes a slide 11 and a slider 10 arranged at the bottom of the first bracket 31. The slide 11 extends along the moving direction of the product 2 to be detected. The slider 10 is slidably arranged in the slide 11. By setting the slider 10 and the slide 11, the first bracket 31 can slide along the slide 11, and then the sensor 30 arranged on the first bracket 31 slides relative to the detection member 1 to adjust the distance between the sensor 30 and the detection member 1, so as to adapt to the detection of different products 2 to be detected, and the applicability is strong.

[0035] In some embodiments of the utility model, the detection member 1 includes a rod body, and a guide member 5 is provided on the outer sleeve of the rod body. The guide member 5 is used to guide the movement of the rod body so that the rod body moves axially relative to the guide member 5. In this embodiment, a tip is provided at one end of the rod body close to the product 2 to be detected, and the tip can be inserted into the hole 21 to be detected. The guide member 5 includes a guide sleeve, and a second bracket 6 is provided at the bottom of the guide sleeve. The guide sleeve is fixedly arranged on the top of the second bracket 6. The guide sleeve can guide the movement of the rod body to ensure that the rod body moves along the guide sleeve. The axis of the guide sleeve, the axis of the rod body and the axis of the proximity sensor coincide, so that when the rod body moves relative to the guide sleeve, the movement direction of the rod body corresponds to the proximity sensor, ensuring the accuracy of the induction and the detection effect.

[0036] In other embodiments, the guide member 5 may also be a guide rod provided on the rod body to guide the movement of the rod body, but this embodiment is not limited to this.

[0037] In some embodiments of the utility model, the detection assembly further includes an elastic member 7, which is sleeved on one end of the rod body close to the sensing member, one end of the elastic member 7 is connected to the guide sleeve, and the other end of the elastic member 7 is connected to the end of the rod body. In this embodiment, the elastic member 7 includes a spring, which is sleeved on the outside of the rod body, and a limiting portion is provided at one end of the rod body close to the proximity sensor, and one end of the spring close to the limiting portion is connected to the limiting portion, so that the end of the spring close to the limiting portion is limited, and the other end of the spring is connected to the end of the guide sleeve. When the hole 21 to be detected is blocked, the rod body is pushed to move toward the end close to the proximity sensor, so that the spring is stretched by the movement of the rod body. When the blocked hole is cleared, the rod body is reset under the elastic action of the spring, and manual reset is not required, thereby improving detection efficiency and saving manpower.

[0038] In some embodiments of the utility model, the rod body is a metal part or a plastic part. When the rod body rubs against the surface of the detected product during detection, the rod body made of plastic will not cause wear to the surface of the detected product, but the surface of the detected product will cause wear to the surface of the rod body, so the rod body needs to be replaced regularly. In this embodiment, the rod body can be a nylon plastic part. The rod body made of metal will not wear for a long time, but the rod body will wear the surface of the detected product. Therefore, technicians in this field can select a rod body of suitable material according to the material of the detected product and the required detection accuracy.

[0039] When the blockage detection device of the utility model is working, the robot clamps the product 2 to be detected and moves it to a preset position, aligns the hole 21 to be detected with the rod body, and then moves the product toward the rod body for a distance (i.e. Figure 2 If the hole 21 to be detected is blocked, the rod body will be driven by resistance to move the magnet to the end close to the proximity sensor, so that the magnet is within the sensing distance of the proximity sensor. At this time, the magnet triggers the proximity sensor, which means that the hole 21 to be detected is blocked. The proximity sensor sends the sensing signal to the controller, and the controller controls the alarm 8 to alarm to remind the personnel to clean it. When the blocked hole is manually cleaned, the rod body is reset under the elastic action of the spring. When the rod body can pass through the hole 21 to be detected without being moved by force, the magnet is not within the sensing distance of the proximity sensor, which means that the hole 21 to be detected is not blocked, and the above operation can be repeated to make the device operate normally.

[0040] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that can be easily thought of by a person skilled in the art within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
