Description

Technical Field

[0001] This utility model relates to the field of cylinder testing technology, specifically a cylinder block porosity testing device. Background Technology

[0002] As a key actuator in industrial automation, the airtightness of the cylinder body directly affects the operational stability and service life of the equipment. During manufacturing, due to factors such as casting processes or machining, tiny defects such as pores or cracks may exist inside the cylinder body. These defects can cause leakage under high-pressure operating conditions, severely impacting the operating efficiency and safety performance of the equipment. Therefore, rigorous airtightness testing must be performed during cylinder production.

[0003] Currently, the industry generally uses the water immersion leak detection method to test the airtightness of cylinders. Although the existing testing equipment can achieve basic testing functions, it requires a complete shutdown during the testing process to install and disassemble the cylinder under test, resulting in a long downtime during the testing process, which seriously restricts the continuous testing efficiency of the production line. Utility Model Content

[0004] The purpose of this invention is to provide a cylinder block porosity detection device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A cylinder block porosity detection device, comprising:

[0007] The base has a water tank fixedly connected to its top center, and a partition is fixedly connected to the middle of the water tank.

[0008] The brackets are symmetrically and fixedly connected to the top of both sides of the base. A crossbar is fixedly connected to the top of the brackets on both sides, and a lifting mechanism is provided in the middle of the crossbar.

[0009] A fixing mechanism is provided at the bottom end of the lifting mechanism.

[0010] Preferably, the lifting mechanism includes a movable slot that runs through the middle of the cross frame and racks symmetrically arranged on the inner walls at both ends of the movable slot. A gear is rotatably connected to the middle of the movable slot via a bearing. The gear meshes with the racks on both sides. A motor is fixedly connected to the middle of the front of the cross frame, and the output shaft of the motor is fixedly connected to the gear.

[0011] Preferably, mounting seats are fixedly connected to the top of the cross frame and to both sides of the movable groove. A locking cylinder is fixedly connected to the external end of the mounting seat away from the movable groove. A positioning hole that cooperates with the locking cylinder is opened in the middle of the side of the rack away from the gear.

[0012] Preferably, the fixing mechanism includes a support plate that is laterally fixed to the opposite sides of the bottom ends of the two racks, a mounting bracket that is fixedly connected to the top of the side of the support plate away from the racks, a clamping cylinder that is fixedly connected to the outside of the end of the mounting bracket away from the racks, and a clamping plate that is fixedly connected to the output shaft of the clamping cylinder.

[0013] Preferably, the toothed grooves of the rack are located on its upper half;

[0014] Preferably, drain pipes are fixedly connected to both ends of the bottom front of the water tank.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This cylinder body air hole detection device, through the meshing of gears and racks on both sides in the lifting mechanism, and the synergistic effect of locking cylinder and positioning hole, realizes the alternating lifting and lowering movement of the left and right support plates, so that while one side of the cylinder is being immersed in water for testing, the other side can be loaded and unloaded.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] like Figure 1-4 As shown, this utility model provides a technical solution:

[0025] A cylinder block porosity detection device includes a base 1, a water tank 2 fixedly connected to the top center of the base 1, a partition 3 fixedly connected to the middle of the water tank 2, and brackets 4 symmetrically fixedly connected to the tops of both sides of the base 1. A crossbeam 5 is fixedly connected to the top of the two side brackets 4. A lifting mechanism is provided in the middle of the crossbeam 5. The lifting mechanism includes a movable groove 6 extending through the middle of the crossbeam 5, and racks 7 symmetrically arranged on the inner walls at both ends of the movable groove 6. A gear 8 is rotatably connected to the middle of the movable groove 6 via a bearing. The gear 8 meshes with the racks 7 on both sides. A motor 9 is fixedly connected to the middle of the front of the crossbeam 5. The output shaft of the motor 9 is fixedly connected to the gear 8. A crossbeam 5 is also fixedly connected to the top of the crossbeam 5 on both sides of the movable groove 6. A mounting base 10 is fixedly connected to the rack 7. A locking cylinder 11 is fixedly connected to the end of the mounting base 10 away from the movable groove 6. A positioning hole 12 that cooperates with the locking cylinder 11 is opened in the middle of the side of the rack 7 away from the gear 8. A fixing mechanism is set at the bottom of the lifting mechanism. The fixing mechanism includes a support plate 13 that is horizontally fixedly connected to the opposite sides of the bottom ends of the two racks 7. A mounting bracket 14 is fixedly connected to the top of the side of the support plate 13 away from the rack 7. A clamping cylinder 15 is fixedly connected to the end of the mounting bracket 14 away from the rack 7. A clamping plate 16 is fixedly connected to the output shaft of the clamping cylinder 15. The tooth groove of the rack 7 is set in its upper half. Drain pipes 17 are fixedly connected to both ends of the bottom front of the water tank 2.

[0026] In this embodiment, the alternating lifting and lowering motion of the left and right support plates 13 is achieved through the meshing of the gear 8 and the racks 7 on both sides in the lifting mechanism, as well as the synergistic effect of the locking cylinder 11 and the positioning hole 12. This allows the cylinder on one side to be immersed in water for testing while the cylinder on the other side can be loaded and unloaded. This effectively solves the problem of low testing efficiency caused by the need to stop the existing testing equipment for loading and unloading, and realizes continuous and uninterrupted testing operations.

[0027] Furthermore, by using the clamping cylinder 15 and the clamping plate 16 in the fixing mechanism, the cylinder to be tested can be quickly clamped and fixed. Combined with the alternating working mode of the lifting mechanism, the cylinder loading and unloading operation during the testing process can be carried out simultaneously with the testing operation, which significantly improves the testing efficiency of the production line.

[0028] Working principle: The cylinder body to be tested is fixed to the support plate 13 on one side by the clamping cylinder 15 driving the clamping plate 16, and one air hole of the cylinder is blocked, while the other air hole is connected to the external air supply line; the motor 9 is started to drive the gear 8 to rotate, driving the racks 7 on both sides to move in opposite directions, so that the support plate 13 with the cylinder fixed is lowered and immersed in the water tank 2, while the other support plate 13 is raised to the highest position to install the next cylinder to be tested; when the cylinder is completely immersed in the water, the locking cylinder 11 extends out and inserts into the positioning hole 12 of the rack 7 to achieve positioning and fixation; compressed air is injected into the cylinder through the external air supply line, and the presence of air bubbles in the water is observed to determine whether there are air hole defects in the cylinder body; after the test is completed, the motor 9 reverses to raise the support plate 13 away from the water surface, while the other support plate 13 drives the next installed cylinder to lower and be immersed in the water for testing. This cycle is repeated to achieve continuous testing. During the test, the water level of the water tank 2 can be adjusted or the water can be changed through the drain pipe 17.

[0029] In the specific implementation of this technical solution, the connection between the cylinder to be tested and the external air supply pipeline can be configured with conventional pneumatic quick couplings (such as threaded connections, clamp connections, or plug-in connections) found in existing technologies. Although such connection devices are not described in detail in the technical solution, they are supporting components that can be conventionally selected by those skilled in the art based on actual testing needs. Their structural form and working principle follow the well-known technology in this field and do not affect the implementation of the core innovation of this solution.

[0030] In practical applications, pneumatic quick couplings are mainly used to achieve rapid connection and separation between the detection air circuit and the cylinder under test. However, their specific types and connection methods can be adjusted according to the automation level of the production line and the detection cycle requirements, all of which fall within the reasonable extension range of this technical solution.

[0031] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
