Description

Technical Field

[0001] This utility model relates to the field of testing fixture technology, and in particular to a testing device for positioning machine housings. Background Technology

[0002] A housing is a protective shell used to protect kinetic energy equipment, such as a cylinder. The housing is designed with airflow channels on its inner wall to allow airflow into the housing. During the production of the housing, it is usually required to perform operations such as molding, cutting, and grinding. There are debris left on the housing, so it is necessary to flush the housing with water to check the airflow channels to confirm that the channel inlet and outlet are unobstructed and that there are no foreign objects or processing residues inside the channels.

[0003] Existing water flushing inspections of machine casings typically involve workers placing the casing on a workbench, holding it down with one hand, and using the other to align the water hose opening with the airflow channel inlet. This operation is cumbersome. Furthermore, water flushing inspections usually involve using a high-pressure water gun for rapid rinsing. During this process, the water flow can back up when encountering resistance in the airflow channel, potentially splashing onto workers, such as into their eyes, posing a safety hazard. Secondly, the lack of drainage mechanisms on the workbench allows splashed water to flow onto the floor, creating a slippery surface and again increasing the risk of accidents. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing the following technical solution:

[0005] A detection device for positioning a housing includes a lower plate, which includes a base plate. A guide plate is fixedly installed on the upper surface of the base plate, and a drainage hole is provided in the middle of the base plate. Support seats are fixedly installed on both sides of the base plate. An upper plate is placed on the upper part of the base plate, and the upper plate includes a positioning plate for positioning the housing. A placement groove is provided on the surface of the positioning plate, and an expansion spline is provided above the placement groove. A limiting block for auxiliary limiting is installed on both sides of the positioning plate. A lifting component for adjusting the height of the positioning plate is fixedly installed on one side of the support seat. The lifting component includes a push rod. One end of the push rod is fixedly installed on one side of the support seat, and the other end of the push rod is fixedly connected to the bottom of the positioning plate. Buffer components for auxiliary buffering are fixedly installed on both sides of the base plate.

[0006] As an improvement to the above technical solution, the lifting assembly further includes a mounting block, a first hinge seat, and a second hinge seat. The mounting block is fixedly installed on one side of the support base, the first hinge seat is fixedly installed on the upper part of the mounting block, and the two sides of the second hinge seat are bolted to the bottom of the positioning plate. One end of the second hinge seat is connected to the telescopic end of the push rod.

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0020] Please see Figure 1-5 This utility model provides a technical solution:

[0021] The detection device for positioning the housing includes a lower plate 1, which includes a base plate 11. A guide plate 12 is fixedly installed on the upper surface of the base plate 11 by welding. A drain hole 13 is provided in the middle of the base plate 11. Support seats 14 are fixedly installed on both sides of the base plate 11 by welding. An upper plate 2 is placed on the upper part of the base plate 11. The upper plate 2 includes a positioning plate 21 for positioning the housing. A placement groove 22 is provided on the surface of the positioning plate 21. An expansion spline 23 is provided above the placement groove 22. Both sides of the support base 11 are equipped with auxiliary limiting blocks 24. A lifting component 3 for adjusting the height of the positioning plate 21 is fixedly installed on one side of the support base 14. The lifting component 3 includes a push rod 33. One end of the push rod 33 is fixedly installed on one side of the support base 14 by bolt hinge. The other end of the push rod 33 is fixedly connected to the bottom of the positioning plate 21 by bolt hinge. Buffer components 4 for auxiliary buffering are fixedly installed on both sides of the base plate 11. The buffer components 4 are bolted to the upper part of the support plate 41.

[0022] In this embodiment, the bottom plate 11 of the lower plate 1 serves as the foundation of the entire device. The design of the bottom plate 11 needs to be stable and able to withstand a certain weight and pressure. The guide plate 12 helps to guide the wastewater generated during the flushing process to the drain hole 13, reducing water stains and cleaning work. The support base 14 is not only used to support the upper plate 2, but also serves as the fixing point of the lifting component 3. The positioning plate 21 of the upper plate 2 is the work station for placing the housing. The placement groove 22 is designed according to the shape and size of the housing to ensure that the housing can be placed stably on the positioning plate 21. The expansion spline 23 can firmly clamp the housing to prevent the housing from moving or falling off during the flushing inspection. This design is both convenient and safe. The push rod 33 lifts the positioning plate 21 to a suitable height for the flushing operation. The design of the buffer component 4 is used to reduce the impact and vibration of the positioning plate 21 during the lifting or lowering process, protecting the housing and the detection device itself.

[0023] Operating Procedure: Adjust the expansion spline 23 to a relaxed state. Carefully place the housing to be tested into the placement slot 22 on the positioning plate 21 of the upper plate 2. Adjust the expansion spline 23 according to the shape and size of the housing to expand and firmly clamp the housing. Activate the lifting assembly 3 to lift the upper plate 2 and the fixed housing to a suitable height via the push rod 33 for water flushing inspection. During the lifting process, the buffer assembly 4 will reduce impact and vibration, protecting the housing and the testing device. Aim the nozzle of the high-pressure water gun at the channel inlet. During the flushing process, carefully observe the water flow in the channel, noting whether the water flows smoothly through the channel inlet and outlet, and whether any foreign objects or processing residues are flushed out. If channel blockage, poor water flow, or foreign object residue is found, record and mark the location for subsequent processing. Wastewater flows through the guide plate 12 to the drain hole 13 and is finally discharged outside the device. Observe the casing for leaks, deformation, or other abnormalities, and record the inspection results for subsequent analysis and processing. After completing the flushing inspection, lower the upper plate 2 back to its original position using the lifting assembly 3. During the descent of the positioning plate 21, the buffer assembly 4 protects the casing and detection device from impact and vibration. Remove the casing, adjust the expansion spline 23 to a relaxed state, and remove the casing from the placement slot 22. The well-designed placement slot 22 and expansion spline 23 can quickly and accurately fix the casing, reducing the time required for placement and fixing, thereby improving inspection efficiency and protecting the casing and device. The design of the buffer assembly 4 effectively reduces the impact and vibration of the upper plate 2 during lifting and lowering, protecting the casing and inspection device from damage. The design of the guide plate 12 and drain hole 13 allows wastewater to drain smoothly, reducing water stains and the burden of cleaning work. The operation is simple, reduces safety risks during operation, and ensures the personal safety of operators.

[0024] Specifically, the lifting assembly 3 also includes a mounting block 31, a first hinge seat 32, and a second hinge seat 34. The mounting block 31 is fixedly installed on one side of the support base 14 by bolt installation. The first hinge seat 32 is fixedly installed on the upper part of the mounting block 31 by bolt installation. The bolts on both sides of the second hinge seat 34 are installed on the bottom of the positioning plate 21. One end of the second hinge seat 34 is connected to the telescopic end of the push rod 33.

[0025] In this embodiment, the mounting block 31 is bolted to one side of the support base 14, ensuring that the motor and the hinge base can be stably mounted on the support base 14 and withstand the force and torque generated during the lifting process. The push rod 33 is at one end of the first hinge base 32, driving the positioning plate 21 to rotate. When the push rod 33 is started, the extension and retraction movement of the push rod 33 is transmitted to the positioning plate 21 through the second hinge base 34, causing the positioning plate 21 and the housing on it to move vertically. During the lifting process, the buffer component 4 will play a role in reducing impact and vibration. Through the drive of the motor, the automatic control of the lifting component 3 is realized, improving the automation level of the detection process.

[0026] Specifically, the buffer assembly 4 includes a support plate 41, a buffer 42, a buffer pad 43, and a limiting rod 44. The support plate 41 is fixedly installed on both sides of the base plate 11, the buffer 42 is fixedly installed on the upper part of the support plate 41 by bolt installation, the buffer pad 43 is sleeved on the top of the buffer 42, and the bottom of the limiting rod 44 is fixedly installed inside the buffer 42 by bolt installation.

[0027] In this embodiment, the support plate 41 is fixedly installed on the base plate 11 with bolts to ensure that it will not loosen or fall off during use. The buffer 42 can be a hydraulic buffer. The buffer 42 is the core component of the buffer assembly 4. The hydraulic buffer is bolted to the upper part of the support plate 41. When the housing comes into contact with the buffer pad 43 during lifting or lowering, the buffer 42 will absorb and reduce the resulting impact force and vibration. The buffer pad 43 is usually made of rubber elastic material, which has good wear resistance, corrosion resistance and elastic recovery ability. The buffer pad 43 is fixedly installed by sleeve on the top of the buffer 42 to ensure that it can fit tightly against the housing and effectively absorb the impact force. When the housing descends to a certain position, the limit rod 44 will prevent the buffer 42 from continuing to compress, thereby preventing the housing from colliding or being damaged with other components of the detection device.

[0028] Specifically, a limiting groove 241 is formed on the surface of the limiting block 24, and the upper part of the limiting rod 44 is inserted into the limiting groove 241. In this embodiment, the main function of the limiting groove 241 is to provide a precise guiding and limiting function, ensuring that the housing can move along a predetermined path and position during descent. The limiting rod 44 is part of the buffer assembly 4, and its upper part is inserted into the limiting groove 241. By limiting the descent position of the housing, the limiting groove 241 and the limiting rod 44 together constitute a safety protection device, avoiding the risk of collision or compression between the housing and other components of the detection device.

[0029] Specifically, the guide plate 12 has a wave-shaped structure. In this embodiment, the wave-shaped structure can guide the water flow more effectively, allowing the wastewater to flow along a predetermined path during the rinsing process. Compared with the planar guide plate 12, the wave-shaped design increases the contact area and turbulence of the water flow, which helps the wastewater flow to the drain hole 13 more quickly, reducing water stains and the difficulty of cleaning.

It should be noted that those skilled in the art can make various modifications and improvements without departing from the technical solution of the present invention, and these should also be considered within the scope of protection of the present invention.
