Description

Technical Field

[0001] This utility model relates to the field of testing devices, and in particular to a device for testing the compressive strength of mechanical parts. Background Technology

[0002] Metal parts refer to a collective term for metal blocks, metal rods, metal tubes, etc. of various specifications and shapes made of metal materials. They are widely used in many fields such as machinery manufacturing, automobiles, aviation, and aerospace. When designing and manufacturing metal parts, it is necessary to use testing equipment to conduct compressive strength tests on their mechanical properties.

[0003] Existing testing devices apply continuous pressure to metal parts through a pressurizing structure during use. During the application of pressure, vibrations usually occur under the action of force, generating noise. Furthermore, due to changes in pressure, the vibrations may intensify, leading to an increase in noise. This strong noise can easily cause harm such as hearing loss and permanent deafness.

[0004] Therefore, in view of the harm that strong noise can easily cause to hearing loss and permanent deafness, a mechanical parts compressive strength testing device can be designed. By designing and installing a soundproof enclosure around the testing platform to block the transmission of noise, the above problems can be solved. Utility Model Content

[0005] In order to overcome the limitations of existing detection devices, which require continuous pressure to be applied to metal parts during use, vibration and noise are usually generated under the action of force. At the same time, due to changes in pressure, the vibration may be aggravated, resulting in increased noise. This strong noise can easily lead to problems such as hearing loss and permanent deafness.

[0006] The technical solution of this utility model is as follows: a mechanical parts compressive strength testing device, including a testing platform, a pressurizing component, a front door, side railings and a rear railing; a pressurizing component for pressurizing mechanical parts is provided above the testing platform, the pressurizing component includes a column and a crossbeam, a rear railing for absorbing and blocking noise is provided at the rear end of the testing platform, two sets of side railings for assisting in blocking noise are provided on both sides of the testing platform, and a front door is provided at the front end of the testing platform.

[0007] Preferably, by combining a front door, side railings, and rear railings, this application addresses the problem of existing testing devices on the market being prone to damaging the hearing of workers due to strong noise. By surrounding the testing platform with a front door, side railings, and rear railings that have sound insulation and sound absorption structures, strong noise is significantly attenuated when it passes through the front door, side railings, and rear railings, thereby protecting the hearing safety of workers.

[0008] Preferably, there are two sets of columns, which are located at the center edges of the two sides of the testing platform. The crossbeam is mounted on the upper end of the two sets of columns. The center of the crossbeam has a pressure hole, and the center of the pressure hole has a pressure column. The lower end of the pressure column has a pressure hammer. By combining the columns and the crossbeam, the pressure assembly can be fixed above the testing platform to apply pressure to the mechanical parts for pressure resistance testing of the metal parts.

[0009] Preferably, the upper end of the pressure column is provided with a transmission beam, and two sets of hydraulic rods are respectively provided below both ends of the transmission beam. The upper ends of the two sets of hydraulic rods are connected to the transmission beam, and two sets of hydraulic cylinders are matched with the two sets of hydraulic rods. Both sets of hydraulic cylinders are located at the lower end of the crossbeam, and the lower ends of the two sets of hydraulic rods pass through the crossbeam and are connected to the two sets of hydraulic cylinders. Through the combination of the two sets of hydraulic rods and the two sets of hydraulic cylinders, the hydraulic cylinders can drive the hydraulic rods to retract during the pressurization process. The hydraulic rods drive the pressure column to press down through the transmission beam, thereby causing the pressure column to push the pressure hammer to press on the mechanical parts and apply pressure.

[0010] Preferably, the testing platform has a rear locking groove at the rear edge, side locking grooves at both sides, a door groove at the front, movable holes at both sides of the door groove, and a positioning frame at the top. The positioning frame has a positioning groove at its center. The combination of the positioning frame and the positioning groove allows the metal parts to be positioned when pressure is applied.

[0011] Preferably, the lower end of the rear fence is provided with a rear locking strip, and the lower end of the side fence is provided with a side locking strip. The rear locking strip and the side locking strip are respectively matched and locked with the rear locking groove and the side locking groove. By combining the rear locking strip and the side locking strip, the rear fence and the side fence can be installed on both sides and the rear end of the testing platform respectively.

[0012] Preferably, the upper ends of the side railings, rear railings, and front door are all provided with sound insulation grooves. Multiple sets of partitions are linearly arranged inside the sound insulation grooves, and multiple sets of sound insulation cavities are opened between the multiple sets of partitions. The upper ends of the rear railings, side railings, and front door are respectively provided with a primary cover plate, a secondary cover plate, and a tertiary cover plate. The primary cover plate, the secondary cover plate, and the tertiary cover plate are matched and fastened with the sound insulation grooves. The inner sides of the rear railings, side railings, and front door are all fitted with sound-absorbing cotton. Through the combination of sound-absorbing cotton and multiple sets of sound insulation cavities, when noise passes through the sound-absorbing cotton, the sound-absorbing cotton can absorb part of the noise sound waves. When the sound waves penetrate the sound insulation cavities, the sound insulation cavities act as damping layers, which consume the energy of the sound and cause the sound to gradually attenuate.

[0013] Preferably, the lower end of the front door is provided with a movable shaft, which is located inside the door groove. Both ends of the movable shaft extend into the interior of the movable hole. Two sets of magnetic strips are attached to the inner ends of the front door. By combining the magnetic strips with the movable shaft, the front door can be opened and closed by rotating along the movable hole via the movable shaft, and closed by being attracted by the magnetic strips.

[0014] The beneficial effects of this utility model are:

[0015] 1. By combining a front door, side railings, and rear railings, this application addresses the problem of existing testing devices on the market being prone to damaging workers' hearing due to strong noise. This is achieved by using sound-absorbing and sound-insulating structures around the front door, side railings, and rear railings of the testing platform. This significantly attenuates strong noise as it passes through these railings, protecting workers' hearing. A combination of columns and beams allows the pressure-applying components to be fixed above the testing platform to apply pressure to mechanical parts for pressure testing. Two sets of hydraulic rods and two sets of hydraulic cylinders combine to drive the hydraulic rods to contract during pressurization. The hydraulic rods, through a transmission beam, drive the pressure column downwards, causing the pressure column to push the pressure hammer onto the mechanical parts. A combination of sound-absorbing cotton and multiple sound-insulating cavities allows the cotton to absorb some of the noise waves as they pass through. The sound-insulating cavities act as damping layers, consuming sound energy and gradually attenuating the sound. Attached Figure Description

A pressure hole 206 is provided at the center of the crossbeam 202, and a pressure column 205 is located at the center of the pressure hole 206. A pressure hammer 208 is located at the lower end of the pressure column 205. By combining the columns 201 and the crossbeam 202, the pressure assembly 2 can be fixed above the testing platform 1 to apply pressure to the mechanical parts for pressure resistance testing of the metal parts. A transmission beam 204 is provided at the upper end of the pressure column 205. Two sets of hydraulic rods 203 are respectively provided below both ends of the transmission beam 204.

Two sets of hydraulic cylinders 207 are matched with the two sets of hydraulic rods 203, and both sets of hydraulic cylinders 207 are located at the lower end of the crossbeam 202. The lower end of the hydraulic rod 203 passes through the crossbeam 202 and connects to two sets of hydraulic cylinders 207. The combination of the two sets of hydraulic rods 203 and the two sets of hydraulic cylinders 207 allows the hydraulic cylinders 207 to drive the hydraulic rods 203 to retract during pressurization. The hydraulic rods 203 drive the pressure column 205 to press down through the transmission beam 204, thereby pushing the pressure hammer 208 to press on the mechanical parts and apply pressure.

Through the combination of the rear locking strip 15 and the side locking strip 19, the rear fence 3 and the side fence 4 can be installed on the sides and rear end of the testing platform 1 respectively. The upper ends of the side fence 4, the rear fence 3, and the front door 5 are all provided with sound insulation grooves 12.

Matching and fastening, the inner sides of the rear fence 3, side fence 4 and front door 5 are all fitted with sound-absorbing cotton 17. The sound-absorbing cotton 17 is combined with multiple sets of sound insulation cavities 14, so that when noise passes through the sound-absorbing cotton 17, the sound-absorbing cotton 17 can absorb part of the noise sound waves. When the sound waves penetrate the sound insulation cavity 14, the sound insulation cavity 14 acts as a damping layer, which will consume the sound energy and make the sound gradually attenuate. The lower end of the front door 5 is provided with a movable shaft 22. The movable shaft 22 is located inside the door groove 10. The two ends of the movable shaft 22 extend into the interior of the movable hole 11 respectively. Two sets of magnetic strips 21 are attached to the inner ends of the front door 5.

[0026] During operation, the combination of column 201 and crossbeam 202 allows the pressurizing assembly 2 to be fixed above the testing table 1 to apply pressure to the mechanical parts for pressure resistance testing of the metal parts. During the pressurization process, hydraulic cylinder 207 can drive hydraulic rod 203 to retract. Hydraulic rod 203 drives pressurizing column 205 downward through transmission beam 204, thereby causing pressurizing column 205 to push pressurizing hammer 208 to press on the mechanical parts to apply pressure.

[0027] When noise is generated, the sound-absorbing cotton 17 is combined with multiple sets of sound insulation cavities 14 so that when the noise passes through the sound-absorbing cotton 17, the sound-absorbing cotton 17 can absorb part of the noise sound waves. When the sound waves penetrate the sound insulation cavity 14, the sound insulation cavity 14 acts as a damping layer, which consumes the energy of the sound and causes the sound to gradually attenuate.

[0028] Through the above steps, by combining the front door 5, side railing 4 and rear railing 3, compared with the current testing devices on the market, which are prone to damage to the hearing of staff due to strong noise, this application protects the hearing safety of staff by surrounding the testing platform 1 with the front door 5, side railing 4 and rear railing 3 which have sound insulation and sound absorption structures.
