Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic universal testing machines, in particular to a hydraulic universal testing machine. Background Art

[0002] Hydraulic universal testing machines are mainly used for mechanical property tests of metals, non-metals, composite materials and products in ways such as tension, compression, bending, and shearing.

[0003] A hydraulic universal testing machine disclosed in Chinese Patent CN214408406U includes a frame, an upper fixture and a lower fixture arranged on the frame. The frame is also provided with a driving member for driving the upper fixture to slide up and down. The upper fixture includes a clamping body, a cylinder arranged in the frame body, a first plate and a second plate hinged to the piston rod of the cylinder. The side wall of the first plate close to the piston rod of the cylinder abuts against the second plate. The clamping body is provided with guide surfaces abutting against the opposite surfaces of the first plate and the second plate. The guide surfaces are used to abut against the first plate and the second plate to gather towards the middle to clamp the steel bar. The lower fixture has the same structure as the upper fixture. Although this patent clamps the steel bar by setting the first plate and the second plate and using the drive of the cylinder, so that the first plate and the second plate gather and clamp the steel bar under the abutment of the guide surfaces, instead of manually adjusting the clamping member to clamp the steel bar, which shortens the time and labor required for clamping the steel bar, thus having the advantage of being convenient for the staff to clamp the steel bar.

[0004] However, the above testing machine does not have a cleaning component. When the test material breaks, the generated debris often remains in the jaws and the device, which not only affects the normal closing and clamping effect of the jaws, but also increases the difficulty of subsequent manual cleaning. Manual cleaning is time-consuming and laborious, and is also easily scratched by the tips of some debris, and does not have a protective cover for protection. Summary of the Utility Model

[0005] In order to solve the technical problem of the existing difficult manual cleaning, the utility model provides a hydraulic universal testing machine.

[0006] The technical solution of the utility model is realized through the following scheme: A hydraulic universal testing machine includes a hydraulic universal testing machine, a protective cover and a cleaning carrier. The protective cover is installed on the hydraulic universal testing machine. The hydraulic universal testing machine is clamped with the cleaning carrier through a clamping member. The working surface of the cleaning carrier is provided with a pneumatic cleaning component and a dust suction component. The pneumatic cleaning component is movably installed on the working surface of the cleaning carrier through a first screw component. The pneumatic cleaning component is adapted to the clamping part of the hydraulic universal testing machine.

[0007] Through the above technical solutions, the cleaning carrier vehicle is flexibly clamped on the hydraulic universal testing machine through the clamping parts, and the flexibility of the cleaning component is effectively improved in cooperation with the first lead screw assembly. The protective housing not only effectively protects the main components of the testing machine from the influence of the external environment, but also provides a relatively enclosed working environment, reducing the splashing of debris generated during the test into the surrounding environment. The pneumatic cleaning component and the dust suction component can quickly and efficiently carry out the cleaning work. After the pneumatic cleaning component loosens and raises debris, dust, etc., the dust suction component can quickly suck it away, avoiding the problems of secondary pollution and incomplete cleaning, thereby reducing the risk of the staff being scratched by debris and improving the cleaning efficiency at the same time.

[0008] Preferably, the pneumatic cleaning component includes a first pneumatic cleaning pipe, a second pneumatic cleaning pipe and a pneumatic cleaning seat. The first pneumatic cleaning pipe is fixedly installed on the pneumatic cleaning seat. The second pneumatic cleaning pipe is movably installed on the pneumatic cleaning seat through a second lead screw assembly. The first pneumatic cleaning pipe and the second pneumatic cleaning pipe have the same structure. The pneumatic cleaning seat is movably installed on the cleaning carrier vehicle through a first lead screw assembly.

[0009] Preferably, the first pneumatic cleaning pipe includes a blower and a ventilation pipe. The blower is connected to the ventilation pipe. The ventilation pipe is adapted to the clamping part of the hydraulic universal testing machine. A plurality of air blowing ports are opened on the ventilation pipe, and filter screen plates are provided at the plurality of air blowing ports.

[0010] Through the above technical solutions, the second pneumatic cleaning pipe is movably installed on the pneumatic cleaning seat through the second lead screw assembly, enhancing the flexibility of cleaning. The staff can adjust the position of the second pneumatic cleaning pipe according to the actual situation of the lower clamping part of the testing machine, so as to achieve precise cleaning of the lower clamping part at different working positions. The air flow impact can effectively loosen and raise debris, dust, etc., laying a foundation for the subsequent cleaning work of the dust suction component. The filter screen plate can effectively prevent large debris or foreign objects from entering the ventilation pipe and protect the normal operation of the blower and the ventilation pipe.

[0011] Preferably, the dust suction component includes a first dust collector, an air suction pipe, a first support block, a second support block and a second dust collector. The first dust collector is connected to the first support block through the air suction pipe. The second dust collector is connected to the second support block through the air suction pipe. The number of air suction pipes is two. Dust suction ports are opened on both the first support block and the second support block.

[0012] Preferably, the first support block is located on one side of the first pneumatic cleaning pipe close to the first dust collector, and the second support block is located on one side of the second pneumatic cleaning pipe close to the second dust collector.

[0013] Preferably, a clamping groove adapted to the clamping part is opened on the hydraulic universal testing machine.

[0014] Preferably, a controller is provided at the handle of the cleaning carrier vehicle, and the pneumatic cleaning assembly, the dust suction assembly, the first lead screw assembly and the second lead screw assembly are all electrically connected to the controller.

[0015] Through the above technical solutions, the design of the double dust suction system improves the dust suction efficiency, can more quickly remove the debris and dust in the pneumatic cleaning assembly and its surrounding areas, and the dust suction port makes the dust suction range wider, can cover more cleaning areas, improves the comprehensiveness and effect of cleaning, and works in coordination with the pneumatic cleaning assembly, greatly improving the cleaning efficiency and effect.

The pneumatic cleaning assembly and the dust suction assembly can quickly and efficiently carry out the cleaning work. After the pneumatic cleaning assembly loosens and raises the debris, dust, etc., the dust suction assembly can quickly suck them away, avoiding the problems of secondary pollution and incomplete cleaning, thereby reducing the risk of staff being scratched by debris and improving the cleaning efficiency at the same time.

Detailed implementation manners

[0026] In order to be able to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the drawings and embodiments.

[0027] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the specific embodiments disclosed in the following specification. The present utility model will be further described in detail below with reference to the drawings.

[0028] A hydraulic universal testing machine, as Figures 1 - 5As shown, it includes a hydraulic universal testing machine, a protective cover shell 1 and a cleaning carrier. The hydraulic universal testing machine is installed with a protective cover shell 1. The hydraulic universal testing machine is clamped to the cleaning carrier through a clamping piece 6. The working surface of the cleaning carrier is provided with a pneumatic cleaning component 2 and a dust suction component 5. The pneumatic cleaning component 2 is movably installed on the working surface of the cleaning carrier through a first screw component 3. The pneumatic cleaning component 2 is adapted to the clamping portion of the hydraulic universal testing machine. The protective cover shell 1 wraps the hydraulic universal testing machine and has front and rear doors. The hydraulic universal testing machine is provided with a clamping groove adapted to the clamping piece 6. The clamping groove is opened on the base of the hydraulic universal testing machine, opposite to the clamping piece 6 at the front end of the cleaning carrier, and away from the clamping groove. One side is a measuring pulling door, and the side close to the card slot is a lifting door. The lifting door is controlled by a screw assembly to rise and fall, so that the cleaning carrier can be connected and cleaned when not in use. The clamping part 6 can be easily and at any time separated from the hydraulic universal testing machine to avoid damage to the cleaning carrier due to the strong kinetic energy generated by the breakage of the object when the hydraulic universal testing machine is working, thereby extending its service life. The wheels at the bottom of the cleaning carrier are preferably brake wheels, and the clamping part is blown by the pneumatic cleaning component 2. The blown debris is absorbed by the dust suction component 5, which effectively cleans the debris generated after the test material breaks, thereby significantly improving the cleaning efficiency and reducing the time and labor of manual cleaning.

[0029] like Figure 5 As shown, the clamping member 6 is composed of a reset spring and two connecting blocks. The two connecting blocks are relatively installed in the protruding block in front of the cleaning carrier vehicle. A slideway is provided in the protruding block. The protruding block is adapted to the clamping groove. Grooves adapted to the two connecting blocks are provided on both sides of the clamping groove. When clamping, the connecting block is pressed down. At this time, the protruding connecting blocks on both sides of the protruding block are received in the slideway. The protruding block easily enters the clamping groove of the hydraulic universal testing machine. After releasing, it is reset by the reset spring in the center of the two connecting blocks. At this time, the protruding connecting blocks on both sides of the protruding block pop out to lock the clamping.

[0030] The pneumatic cleaning assembly 2 includes a first pneumatic cleaning pipe 21, a second pneumatic cleaning pipe 22 and a pneumatic cleaning seat 23. The first pneumatic cleaning pipe 21 is fixedly installed on the pneumatic cleaning seat 23. The second pneumatic cleaning pipe 22 is movably installed on the pneumatic cleaning seat 23 through a second lead screw assembly 4. The first pneumatic cleaning pipe 21 and the second pneumatic cleaning pipe 22 have the same structure. The clamping part on the hydraulic universal testing machine is in a fixed state. Therefore, the first pneumatic cleaning pipe 21 is fixedly installed. The second lead screw assembly 4 is installed on the movable seat of the second lead screw assembly 4 and moves up and down. During cleaning, it can be easily adjusted to the position where the lower clamping part of the hydraulic universal testing machine stops, and inserted into the clamping part for blowing. The pneumatic cleaning seat 23 is movably installed on the cleaning carrier vehicle through a first lead screw assembly 3. The pneumatic cleaning seat 23 is driven by the first lead screw assembly 3 to move left and right on the working surface of the cleaning carrier vehicle, so as to drive the two cleaning pipes to insert into or withdraw from the clamping part. The first lead screw assembly 3 is horizontally arranged, and the second lead screw assembly 4 is vertically arranged. The first lead screw assembly 3 is installed on the working surface of the cleaning carrier vehicle, and the second lead screw assembly 4 is installed on the pneumatic cleaning seat 23.

[0031] The first pneumatic cleaning pipe 21 includes a blower and a ventilation pipe. The blower is connected to the ventilation pipe. The ventilation pipe is adapted to the clamping part of the hydraulic universal testing machine. A number of air blowing ports are opened on the ventilation pipe. Filter plates are provided at each of the a number of air blowing ports. The multiple air blowing ports are arranged in a circular array along the axial position of the ventilation pipe. The clamping part of the hydraulic universal testing machine is blown through the air blowing ports on the ventilation pipe to effectively remove dust and impurities. The filter plates on the ventilation pipe effectively prevent debris from entering the ventilation pipe when there is no blowing and cleaning, and improve the service life of the equipment.

[0032] A controller 7 is provided at the handle of the cleaning carrier vehicle. The pneumatic cleaning assembly 2, the dust suction assembly 5, the first lead screw assembly 3 and the second lead screw assembly 4 are all electrically connected to the controller 7. The operation of each device is carried out through the controller 7, reducing manual operation.

[0033] The dust suction assembly 5 includes a first vacuum cleaner 51, a suction pipe 52, a first support block 53, a second support block 54, and a second vacuum cleaner 55. The first vacuum cleaner 51 is connected to the first support block 53 through the suction pipe 52, and the second vacuum cleaner 55 is connected to the second support block 54 through the suction pipe 52. The number of suction pipes 52 is two. Dust suction ports are provided on both the first support block 53 and the second support block 54. The suction pipe 52 is a hose that is long enough and has sufficient toughness. When the first support block 53 and the second support block 54 move along with the first pneumatic cleaning pipe 21 and the second pneumatic cleaning pipe 22, they will not be overly restricted and maintain a high degree of flexibility. The two suction pipes 52 respectively pass through the first support block 53 and the second support block 54 and are connected to the dust suction ports thereon. The first support block 53 is located on the side of the first pneumatic cleaning pipe 21 close to the first vacuum cleaner 51, and the second support block 54 is located on the side of the second pneumatic cleaning pipe 22 close to the second vacuum cleaner 55. The first support block 53 is closely adjacent to the first pneumatic cleaning pipe 21, and the second support block 54 is closely adjacent to the second pneumatic cleaning pipe 22. It is installed on the movable seat of the second lead screw assembly 4 in the same way as the second pneumatic cleaning pipe 22 and moves up and down simultaneously with the second pneumatic cleaning pipe 22. During the cleaning process, the front side sliding door is in the closed state, and only the rear lifting door is opened, ensuring that the dust and impurities blown out during the cleaning process of the two cleaning pipes can be sucked away in a timely and effective manner. The coordinated action of the dust suction assembly 5 and the pneumatic cleaning assembly 2 can form a more comprehensive cleaning effect, ensuring that the clamping part and other key parts of the hydraulic universal testing machine are thoroughly cleaned.

[0034] For the parts and equipment, conventional models in the prior art are adopted, and for the circuit connection, a conventional connection method in the prior art is used, which will not be elaborated here. The content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0035] Working principle: After the hydraulic universal testing machine finishes working, open the front side sliding door to pick up the workpiece. After picking up the workpiece, further close the front side sliding door and raise the rear lifting door. At this time, the operator snaps the cleaning carrier vehicle onto the hydraulic universal testing machine, controls the second lead screw assembly 4 through the controller 7 to drive the second pneumatic cleaning pipe 22 to adjust so that it is adjusted to the relative position with the lower clamping part of the hydraulic universal testing machine. Further start the first lead screw assembly 3 to drive the pneumatic cleaning seat 23 to move, so that the first pneumatic cleaning pipe 21 and the second pneumatic cleaning pipe 22 enter the clamping part of the hydraulic universal testing machine. Further start the blower and the vacuum cleaner to perform blowing and dust suction to complete the cleaning.
