Description

Technical Field

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

[0002] As a key structural component inside the variable frequency generator, the flywheel housing uses high-strength, corrosion-resistant pickled plate as the base material, is formed through a precise stamping process, and supplemented by meticulous subsequent processing to ensure that it perfectly fits the working requirements of the generator. This housing not only bears the weight of the flywheel assembly inside the generator, but also serves as the core link of power transmission and support, and plays a vital role in maintaining the stable operation of the generator. During the production process, the flywheel housing of the variable frequency generator must undergo rigorous pressure resistance testing. The testing device can verify the housing's bearing capacity under extreme working conditions, ensuring the reliability and safety of the flywheel housing of the variable frequency generator when facing various extreme operating conditions.

[0003] The existing Chinese patent with announcement number CN220960980U discloses a pressure resistance testing device, including a base, a removable shell cover is installed on the upper surface of the base, a U-shaped frame is installed on the upper surface of the shell cover, a hydraulic cylinder is installed in the middle position of the upper surface of the horizontal part of the U-shaped frame, the movable end of the hydraulic cylinder passes through the U-shaped frame and is installed with a pressure head for extruding plastic particles, a circular opening is opened in the middle position of the upper surface of the shell cover, a tray for supporting plastic particles is inserted in the circular opening, a plurality of evenly arranged vertical connecting rods are connected and fixed to the lower surface of the tray, a pressure plate is installed at the lower end of the connecting rod, an anchor pressure gauge is provided on the lower side of the pressure plate, the anchor pressure gauge is installed on the upper surface of the base, and a cleaning part is installed on the upper surface of the tray.

[0004] Although the above scheme can perform pressure resistance testing on objects, it lacks fixation of the object to be tested during testing. If the detection point is too offset, the object to be tested may fall out, affecting the progress of the test. In addition, there is a lack of effective protection. If the flywheel housing falls out during testing, it is easy to injure people and pose a safety threat to the operator. Therefore, it does not meet the existing needs. In this regard, we have proposed a flywheel housing detection device. Utility Model Content

[0005] The purpose of the present invention is to provide a flywheel housing detection device to solve the problem that the pressure resistance detection device proposed in the above background technology is prone to lack of effective fixation when performing pressure resistance detection on the flywheel housing, which may cause it to fall out, affect the detection process, and easily injure people.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solutions: a flywheel housing detection device, comprising a main body, wherein a detection cavity is formed on the upper side of the main body;

[0007] The apparatus further comprises a transmission cavity, which is provided on the lower side of the interior of the main body. Three threaded rods equidistantly distributed in an annular shape are rotatably provided on the lower side of the interior of the transmission cavity. The outer sides of the threaded rods are all threadedly connected to a moving block, and one end of the moving block extends into the interior of the detection cavity.

[0008] It also includes an arc-shaped clamping block, which is arranged at the lower end inside the detection cavity, and three arc-shaped clamping blocks are arranged in a circular and equidistant manner. The arc-shaped clamping block is connected to one end of the moving block located inside the detection cavity, and the arc-shaped clamping block slides with the detection cavity. A sliding cavity is provided inside the arc-shaped clamping block, and a number of sliding cavities are distributed in a rectangular array. An extrusion rod is slidably provided inside the sliding cavity, and one end of the extrusion rod extends to the outside of the sliding cavity.

[0009] Preferably, a motor is provided at the lower end of the transmission cavity, a rotating rod is provided at the output end of the motor via a coupling, and the rotating rod is rotatably connected to the transmission cavity.

[0010] Preferably, a first bevel gear is provided on the outer wall of the rotating rod, a second bevel gear is provided at one end of each threaded rod, and the second bevel gear is meshed and connected with the first bevel gear.

[0011] Preferably, three guide rods equidistantly distributed in a circular shape are welded to the upper side of the interior of the transmission cavity, and the guide rods all pass through the moving block and are in sliding engagement with the moving block.

[0012] Preferably, one end of the extrusion rod located inside the sliding cavity is connected to the sliding cavity via a return spring.

[0014] Preferably, a hydraulic cylinder is installed at the upper end of the detection chamber, and a detection head is installed at the output end of the hydraulic cylinder.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] 1. The utility model opens a transmission cavity on the lower side of the main body. When the flywheel housing is tested, the flywheel housing can be placed at the lower end of the detection cavity. After starting the motor, the three moving blocks can be moved in opposite or opposite horizontal straight lines under the meshing transmission of the first bevel gear and the second bevel gear. When the three moving blocks move toward each other, they will drive the arc-shaped clamping blocks to move synchronously, so that the flywheel housing can be clamped and fixed in three directions, thereby effectively preventing the flywheel housing from falling out during subsequent pressure resistance testing, ensuring the smooth progress of the test, and also avoiding accidental injury to the operator, thereby improving safety.

[0017] 2. The utility model provides a plurality of sliding cavities distributed in a rectangular array inside the arc-shaped clamping block, and an extrusion rod is provided inside the slide through a reset spring. Since there are many types of flywheel housings, the outer wall shape is not necessarily circular. When the arc-shaped clamping block is clamped and fixed, the extrusion rod will first contact the flywheel housing with the annular clamping block. The protruding part of the flywheel housing will cause the extrusion rod to squeeze the reset spring, and the concave part of the flywheel housing will cause the reset spring to extend, thereby enabling the arc-shaped clamping block to adaptively fit the different outer wall shapes of the flywheel housing. Whether it is a convex or concave part, a tight and uniform clamping effect can be achieved through the interaction between the extrusion rod and the reset spring, thereby achieving a good fixing effect on the flywheel housing.

[0018] 3. The utility model has a protective door installed on one side of the front end of the main body. The protective door can be closed during inspection, and the inside of the inspection chamber can be observed through the transparent glass window. The protective door can further protect the operator and avoid accidental injury to the operator when the flywheel housing falls out, thereby further improving the protection effect.

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] See also Figure 1-5 , the utility model provides a technical solution: a flywheel housing detection device, comprising a main body 1, wherein a detection cavity 3 is opened on the upper side of the interior of the main body 1;

[0027] It also includes a transmission chamber 6, which is opened on the lower side of the interior of the main body 1. Three threaded rods 7 are rotatably arranged on the lower side of the interior of the transmission chamber 6 and are equidistantly distributed in a ring shape. The outer sides of the threaded rods 7 are all threadedly connected to a moving block 9. One end of the moving block 9 extends into the interior of the detection chamber 3.

[0028] It also includes an arc-shaped clamping block 14, which is arranged at the lower end of the detection cavity 3, and three arc-shaped clamping blocks 14 are equidistantly distributed in a ring shape. The arc-shaped clamping block 14 is connected to one end of the moving block 9 located inside the detection cavity 3, and the arc-shaped clamping block 14 slides with the detection cavity 3. A sliding cavity 16 is provided inside the arc-shaped clamping block 14, and a number of sliding cavities 16 are distributed in a rectangular array. An extrusion rod 15 is slidably provided inside the sliding cavity 16, and one end of the extrusion rod 15 extends to the outside of the sliding cavity 16.

[0029] When in use, open the protective door 2, place the flywheel housing in the detection chamber 3, start the motor 10, and the motor drives the three second bevel gears 13 and the threaded rod 7 to rotate synchronously through the rotating rod 11 and the first bevel gear 12. The threaded rod 7 drives the moving block 9 to slide along the guide rod 8 to achieve relative or opposite movement in the horizontal direction. During this process, the arc-shaped clamping block 14 moves with the moving block 9, and the adaptive adjustment of the extrusion rod 15 and the return spring 17 is utilized to closely fit the various concave and convex surfaces of the flywheel housing. After fixing the flywheel housing, close the protective door 2, and the hydraulic cylinder 4 drives the detection head 5 to descend for detection. The operator can observe the detection process through the transparent glass window 18. The protective door 2 ensures safety and improves the overall protection effect.

[0030] See also Figure 4 A motor 10 is provided at the lower end of the transmission chamber 6. A rotating rod 11 is provided at the output end of the motor 10 through a coupling. The rotating rod 11 is rotatably connected to the transmission chamber 6. The power of the motor 10 can be directly and efficiently transmitted to the rotating rod 11, thereby achieving stable power transmission.

[0031] See also Figure 3 and Figure 4, a first bevel gear 12 is provided on the outer wall of the rotating rod 11, and a second bevel gear 13 is provided at one end of each of the threaded rods 7, and the second bevel gears 13 are meshed and connected with the first bevel gear 12. Through the meshing transmission of the first bevel gear 12 and the second bevel gear 13, the power is dispersed and synchronously transmitted, so that the three threaded rods 7 can rotate simultaneously and synchronously, thereby ensuring the coordination and consistency of the arc-shaped clamping block 14 during the clamping process;

[0032] See also Figure 2 Three guide rods 8 are welded to the upper side of the transmission cavity 6 and are equidistantly distributed in a circular shape. The guide rods 8 all pass through the moving block 9 and slide with the moving block 9. The guide rods 8 provide a stable sliding track for the moving block 9, limiting the rotational freedom of the moving block 9 so that it can only move linearly along the guide rods 8, thereby ensuring the stability and accuracy of the arc-shaped clamping block 14 during the clamping process;

[0033] See also Figure 5 One end of the extrusion rod 15 located inside the sliding cavity 16 is connected to the sliding cavity 16 via a return spring 17. The return spring 17 can be adaptively adjusted according to the shape of the flywheel housing. When the extrusion rod 15 encounters a convex part of the flywheel housing, the return spring 17 is compressed, and when it encounters a concave part, the return spring 17 is extended, thereby achieving a tight and uniform clamping effect of the arc-shaped clamping block 14 on the flywheel housing;

[0034] See also Figure 1 A protective door 2 is installed on one side of the front end of the main body 1, and a transparent glass window 18 is installed inside the protective door 2. The protective door 2 can effectively isolate adverse factors such as noise and splashing that may be generated during the detection process, thereby protecting the safety of the operator; and the transparent glass window 18 allows the operator to clearly observe the situation inside the detection chamber 3 without opening the protective door, thereby facilitating real-time monitoring;

[0035] See also Figure 1 and Figure 2 A hydraulic cylinder 4 is installed at the upper end of the detection chamber 3, and a detection head 5 is installed at the output end of the hydraulic cylinder 4. The hydraulic cylinder 4 can provide stable and controllable thrust, so that the detection head 5 can accurately contact and apply pressure to the flywheel housing to perform pressure resistance testing.

[0036] Working principle: When in use, open the protective door 2 and place the flywheel housing in the middle position of the lower end of the detection chamber 3, start the motor 10, the motor 10 will drive the rotating rod 11 to rotate, and the rotating rod 11 will drive the first bevel gear 12 to rotate. Since the first bevel gear 12 and the three second bevel gears 13 are engaged with each other, the second bevel gear 13 will be driven to rotate synchronously, and the threaded rod 7 will drive the moving block 9 to rotate synchronously. Since the moving blocks 9 are all slidably matched with the guide rod 8, the moving blocks 9 will be axially limited, and the rotation of the three moving blocks 9 will be converted into horizontal linear movement in opposite directions. When the three moving blocks 9 move toward each other, they will drive the arc clamping block 14 to move synchronously. Before the arc clamping block 14 contacts the flywheel housing, the extrusion rod 15 will first contact the flywheel housing. When the flywheel housing contacts the flywheel housing, the protruding part of the flywheel housing will cause the extrusion rod 15 to squeeze the reset spring 17, and the concave part of the flywheel housing will cause the reset spring 17 to extend, so that the arc-shaped clamping block 14 can adaptively fit the different outer wall shapes of the flywheel housing. No matter whether it is a convex or concave part, a tight and uniform clamping effect can be achieved through the interaction between the extrusion rod 15 and the reset spring 17, thereby achieving a good fixing effect on the flywheel housing. After fixing the flywheel housing, close the protective door 2, start the hydraulic cylinder 4 to move the detection head 5 down to contact the flywheel housing for pressure resistance testing, and the operator can observe the inside of the detection chamber 3 through the transparent glass window 18. The protective door 2 can protect the operator to avoid accidental injury to the operator when the flywheel housing falls out, thereby improving the protection effect.

Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and all variations within the meaning and range of equivalents of the claims are intended to be encompassed within the present invention.
