Description

Technical Field

[0001] This utility model relates to the field of universal testing machine technology, specifically to a clamping device for a microcomputer-controlled electronic universal testing machine. Background Technology

[0002] A universal testing machine is a material testing machine that integrates tensile, bending, compression, shear, and ring stiffness testing functions. It is mainly used for mechanical property testing of metallic and non-metallic materials and is an ideal testing equipment for industrial and mining enterprises, research institutions, universities, and engineering quality supervision stations. Patent number CN202021714975.8 discloses a clamping device for a microcomputer-controlled electronic universal testing machine. Through the design of the clamping components, it can meet the clamping requirements of different materials and is easy to operate, disassemble, and assemble. However, when using the microcomputer-controlled electronic universal testing machine, the objects clamped between the clamping components are prone to bursting during the test, and the bursting debris can easily fly everywhere, causing certain impacts. Therefore, we propose a clamping device for a microcomputer-controlled electronic universal testing machine. Utility Model Content

[0003] To address the problems in the existing technology, this utility model provides a clamping device for a microcomputer-controlled electronic universal testing machine.

[0004] The technical solution adopted by this utility model to solve its technical problem is a clamping device for a microcomputer-controlled electronic universal testing machine, including a machine body. A bracket is mounted on the top surface of the machine body, and a slot is opened on the outer wall surface of the bracket. There are multiple sets of slots. A frame seat for support is engaged between two sets of slots. A frame plate that fits with the frame seat is hinged to the outer wall surface of the frame seat. A tempered glass plate for protection is installed inside the frame plate. An ear seat for support is integrally constructed on the outer wall surface of the frame plate. A magnetic block is mounted on the opposite side of the ear seat and the frame seat.

[0005] The outer wall surface of the frame plate is integrally constructed with a lug plate for support, and the outer wall surface of the frame base is equipped with lugs that fit the lug plate. There are two sets of lugs, and pin holes are opened on the top surface of the lugs and the top surface of the lug plate. Pins for limiting are inserted into the pin holes.

[0006] By adopting the above technical solution, when using the microcomputer-controlled electronic universal testing machine, the clamping structure inside the bracket can be used to clamp the object and facilitate testing. When installing the object, the frame plate can drive the tempered glass plate to fit with the frame seat on the outside of the bracket. The magnetic blocks on the ear seat on the outside of the frame plate can be magnetically connected with the magnetic blocks on the outside of the frame seat, which facilitates the limiting of the frame plate. This makes the internal clamping structure more stable and reduces the impact of objects scattering everywhere when they break, making the universal testing machine more stable.

[0007] When the frame plate and the frame base are fitted together, the ear plates on the outer side of the frame plate fit together with the two sets of ear blocks on the outer side of the frame base. The pin is then removed so that the pin can be inserted into the pin hole on the top of the ear block and into the pin on the outer side of the ear plate. This makes it easy to limit the position of the frame plate and to lift the pin, thereby releasing the restriction on the frame plate. This makes it easy to open and close the frame plate and to install objects on the clamping structure for testing.

[0008] Specifically, the outer wall surface of the ear plate is hinged with a handle for lifting via a pivot.

[0009] By adopting the above technical solution, the handle makes opening and closing the frame panel simpler and more convenient.

[0010] Specifically, the outer wall surface of the bracket is provided with insertion holes, and there are multiple sets of insertion holes. A support cylinder is screwed into the insertion hole, and a cross slide rod that is inserted into the frame plate is slidably installed in the cylinder. A spring for pushing the cross slide rod to move is assembled in the cylinder.

[0011] By adopting the above technical solution, when the frame seat and the slot on the outside of the bracket are engaged with each other, the spring inside the cylinder seat in the insertion hole on the outside of the bracket can push the cross slide rod, so that one end of the cross slide rod can extend out of the cylinder seat and engage with the frame seat inside the slot. This makes it easy to limit the position of the frame seat engaged inside the slot, so that the frame seat can be stably connected with the bracket and is easy to disassemble and assemble.

[0012] Specifically, a pull block is fitted at one end of the cross slide rod located on the outside of the cylinder seat.

[0013] By adopting the above technical solution, the pull block makes the sliding connection of the cross slide bar simple and convenient.

[0014] Specifically, protective rubber seats are fitted between the two sets of ear blocks and on the outer wall surface of the frame base, and the rubber seats fit into the ear blocks. A protective sponge pad is adhered to the outer wall surface of the frame base.

[0015] By adopting the above technical solution, the sponge pad on the outside of the frame base has good elasticity, making it easy and convenient to open and close the frame plate hinged on the outside of the frame base. At the same time, the rubber seat has good elasticity, making the ear seat on the outside of the frame plate more stable and fit with the rubber seat. In addition, the rubber seat between the two ear blocks can protect the ear plate, so that the ear block can stably fit with the two sets of ear blocks.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. The technical solution of this application, through the design of a bracket, slot, frame base, frame plate, tempered glass plate, ear base, and magnetic block, enables the clamping structure within the bracket to clamp objects and facilitate testing when using a microcomputer-controlled electronic universal testing machine. Furthermore, when installing objects, the frame plate allows the tempered glass plate to engage with the frame base on the outside of the bracket, and the magnetic block on the ear base on the outside of the frame plate magnetically connects with the magnetic block on the outside of the frame base, facilitating the limiting of the frame plate. This allows the internal clamping structure to operate more stably and reduces the impact of objects scattering when they break, thus enabling the universal testing machine to operate more stably.

[0018] 2. The technical solution of this application, through the design of ear plates, ear blocks, pin holes and pins, allows the ear plates on the outer side of the frame plate to engage with the two sets of ear blocks on the outer side of the frame base when the frame plate and the frame base are fitted together. The pins can be removed so that they can be inserted into the pin holes on the top of the ear blocks and into the pins on the outer side of the ear plates. This facilitates the positioning of the frame plate and makes it easy to lift the pins, thereby releasing the restriction on the frame plate. This makes the frame plate easy to open and close, and facilitates the installation of objects on the clamping structure for testing. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figure 1-3This utility model provides a technical solution: a clamping device for a microcomputer-controlled electronic universal testing machine, including a body 1, a bracket 2 mounted on the top surface of the body 1, and a slot 3 with multiple sets of slots 3 on the outer wall surface of the bracket 2. A frame seat 4 for support is clamped between two sets of slots 3, and a frame plate 5 that fits into the frame seat 4 is hinged to the outer wall surface of the frame seat 4. A tempered glass plate 6 for protection is mounted inside the frame plate 5, and an ear seat 7 for support is integrally constructed on the outer wall surface of the frame plate 5. A magnetic block 8 is mounted on the opposite side of the ear seat 7 and the frame seat 4. An ear plate 11 for support is integrally constructed on the outer wall surface of the frame plate 5, and an ear block 10 that fits into the ear plate 11 is mounted on the outer wall surface of the frame seat 4. There are two sets of ear blocks 10, and pin holes 12 are opened on the top surface of the ear block 10 and the top surface of the ear plate 11. A pin 13 for limiting is inserted into the pin hole 12.

[0026] When using the microcomputer-controlled electronic universal testing machine, the clamping structure inside the bracket 2 can clamp the object and facilitate testing. When installing the object, the frame plate 5 can drive the tempered glass plate 6 to fit with the frame seat 4 on the outside of the bracket 2. The magnetic block 8 on the ear seat 7 on the outside of the frame plate 5 can be magnetically connected with the magnetic block 8 on the outside of the frame seat 4, which facilitates the limiting of the frame plate 5. This makes the internal clamping structure more stable and reduces the impact of objects scattering everywhere when they break, making the universal testing machine operate more stably.

[0027] When the frame plate 5 and the frame base 4 are engaged, the ear plate 11 on the outer side of the frame plate 5 engages with the two sets of ear blocks 10 on the outer side of the frame base 4. The pin 13 is then removed so that the pin 13 can be inserted into the pin hole 12 on the top of the ear block 10 and into the pin 13 on the outer side of the ear plate 11. This facilitates the positioning of the frame plate 5 and makes it easy to lift the pin 13, thereby releasing the restriction on the frame plate 5. This allows the frame plate 5 to be opened and closed easily, and facilitates the installation of objects on the clamping structure for testing.

[0028] like Figure 1 and Figure 2 As shown, the outer wall surface of the ear plate 11 is hinged with a handle 14 for lifting via a pivot.

[0029] When in use, the handle 14 makes it easier and more convenient to open and close the frame 5.

[0030] like Figure 1 and Figure 3 As shown, the outer wall surface of the bracket 2 is provided with insertion holes 15, and there are multiple sets of insertion holes 15. A support cylinder 16 is screwed into the insertion hole 15, and a cross slide rod 17 that is inserted into the frame plate 5 is slidably installed in the cylinder 16. A spring 18 for pushing the cross slide rod 17 to move is assembled in the cylinder 16.

[0031] When in use, when the frame base 4 and the slot 3 on the outside of the bracket 2 are engaged with each other, the spring 18 inside the cylinder base 16 in the insertion hole 15 on the outside of the bracket 2 can push the cross slide rod 17, so that one end of the cross slide rod 17 can extend out of the cylinder base 16 and engage with the frame base 4 inside the slot 3. This makes it easy to limit the position of the frame base 4 engaged inside the slot 3, so that the frame base 4 can be stably connected with the bracket 2 and is easy to disassemble and assemble.

[0032] like Figure 1 and Figure 3 As shown, a pull block 19 is fitted at one end of the cross slide bar 17 located outside the cylinder seat 16.

[0033] When in use, the pull block 19 makes the sliding connection of the cross slide bar 17 simple and convenient.

[0034] like Figure 1 and Figure 2 As shown, the two sets of ear blocks 10 are fitted with protective rubber seats 9 on the outer wall surface of the frame base 4, and the rubber seats 9 fit with the ear seats 7. The outer wall surface of the frame base 4 is bonded with a protective sponge pad 20.

[0035] When in use, the sponge pad 20 on the outside of the frame base 4 has good elasticity, making it easy and convenient to open and close the frame plate 5 hinged on the outside of the frame base 4. At the same time, the rubber seat 9 has good elasticity, making the ear seat 7 on the outside of the frame plate 5 more stable and fit together with the rubber seat 9. In addition, the rubber seat 9 between the two ear blocks 10 can protect the ear plate 11, so that the ear block 10 can stably fit together with the two sets of ear blocks 10.

[0036] The working principle and usage process of this utility model are as follows: In use, first install the corresponding structural components in suitable positions. When using the microcomputer-controlled electronic universal testing machine, the clamping structure within the bracket 2 can clamp the object and facilitate testing. When installing the object, the frame plate 5 can drive the tempered glass plate 6 to engage with the frame seat 4 on the outside of the bracket 2. Furthermore, the magnetic blocks 8 on the outer ear seat 7 of the frame plate 5 can magnetically connect with the magnetic blocks 8 on the outer side of the frame seat 4, facilitating the limiting of the frame plate 5. This allows the internal clamping structure to operate more stably and reduces [the risk of damage]. The impact of the object shattering and scattering in all directions makes the universal testing machine operate more stably. At the same time, when the frame plate 5 and the frame base 4 are engaged, the ear plate 11 on the outside of the frame plate 5 and the two sets of ear blocks 10 on the outside of the frame base 4 are engaged. The pin 13 is then removed so that the pin 13 can be inserted into the pin hole 12 on the top of the ear block 10 and into the pin 13 on the outside of the ear plate 11. This makes it easy to limit the position of the frame plate 5 and easy to lift the pin 13, thereby releasing the restriction on the frame plate 5. This makes the frame plate 5 easy to open and close, and makes it easy to install objects on the clamping structure for testing.
