Abstract
Description
Technical Field
[0001] This utility model relates to the field of fixture technology, specifically to a sample handling fixture for a hot pressing sintering furnace. Background Technology
[0002] In the operation of a hot pressing sintering furnace, the handling of samples is a crucial step. Traditional handling methods often suffer from poor clamp stability and are prone to sample damage, which not only affects the integrity of the samples but also reduces the working efficiency of the hot pressing sintering furnace.
[0003] According to a public disclosure (publication number: CN208620813U), a sample handling fixture for a vacuum hot-pressing sintering furnace includes a first clamping block mechanism and a second clamping block mechanism. The end of the first clamping mechanism is movably connected to the end of the second clamping mechanism via a hinge. The fixture has a first groove and a second groove, both of which have anti-slip protrusions. This increases the contact area with the sample surface when the fixture handles the sample, resulting in a more secure grip and preventing damage to internal furnace components due to slippage. The fixture also includes a first telescopic rod and a second telescopic rod, allowing for adjustable fixture length and easier handling.
[0004] In the aforementioned applications, the cooperation between the first and second mechanism components may still result in insufficient overall stability of the fixture and inconvenient operation when gripping samples. Therefore, we propose a sample handling fixture for a hot-pressing sintering furnace. Utility Model Content

[0007] The rotational stabilizing device includes a first fixed block, the side of which is fixedly connected to one end of clamp A.

[0009] The number of spring one is set to two, and they are symmetrical to each other along the vertical central axis of the fixing block one. The number of spring two is set to two, and they are symmetrical to each other along the vertical central axis of the fixing block two.

[0010] The circumferential surface of the first limiting post is slidably connected to the inner circumferential surface of the first through hole, and the circumferential surface of the second limiting post is slidably connected to the inner circumferential surface of the second through hole. Their function is to provide a limiting effect. Because the spring is flexible, this makes the clamping more stable.
[0011] Two through holes are provided, and they are symmetrical about each other along the vertical central axis of the fixing block 1 and the fixing block 2. The side sections of the clamping plate 1 and the clamping plate 2 are set as arcs, which can better fit the surface of the sample when clamping the sample, thereby improving the stability and reliability of clamping.
[0012] According to another aspect, at least one embodiment of this utility model also provides a hot-press sintering furnace sample handling fixture, comprising: a protective auxiliary device provided on the side of the main board, the protective auxiliary device including a connecting column, one end of the connecting column being fixedly connected to the side of the main board, a protective plate being fixedly connected to the end of the connecting column away from the main board, a fixing block; a connecting column being fixedly connected to the side of the main board, the protective plate being fixedly connected to the end of the connecting column away from the main board, a perforated plate being fixedly connected to the side of clamp A; a clamping plate being fixedly connected to the side of clamp B; a clamping post sleeve being fixedly connected to the end of the clamping plate away from clamp B; a clamping post being slidably connected to the inner circumferential surface of the clamping post sleeve; a pressure spring being fixedly connected to the inner side of the clamping post sleeve; an annular clamping plate being fixedly connected to the end of the pressure spring away from the clamping post sleeve; the side of the annular clamping plate penetrating and being fixedly connected to the circumferential surface of the clamping post; its function is to provide protection and self-locking when the sample is taken out at high temperature, thereby enhancing the structural stability and safety of the entire fixture.

[0015] The first type of connecting post has two parts, which are symmetrical about each other along the central axis of the first main board. The second type of connecting post has two parts, which are symmetrical about each other along the central axis of the second main board. Their function is to enhance the structural stability of the entire protection and make the clamp more stable and reliable during use.
[0016] The side sections of the first and second protective plates are L-shaped. The circumferential surface of the clamping post and the through hole on the side of the perforated plate improve the connection stability, prevent the experimental sample from slipping during the handling process, and further enhance the safety performance of the entire fixture.

[0034] like Figures 1-6 As shown, it illustrates a hot-press sintering furnace sample handling fixture according to an embodiment of the present invention, including clamp A1, a main shaft 2 is rotatably connected through the side of clamp A1, clamp B3 is rotatably connected to the circumferential surface of the main shaft 2, and a rotation stabilizing device 4 is provided at the top of clamp A1.
[0035] The rotation stabilizing device 4 includes a fixing block 401, the side of which is fixedly connected to one end of the clamp A1. A rotating sleeve 402 is fixedly connected to the side of the fixing block 401. A rotating shaft 403 is rotatably connected to the inner circumferential surface of the rotating sleeve 402. A main plate 404 is fixedly connected to one end of the rotating shaft 403. A spring 405 is fixedly connected to the side of the main plate 404. A clamping plate 406 is fixedly connected to the side of the spring 405 away from the main plate 404. A limit post 407 is fixedly connected to the side of the clamping plate 406. A through hole 408 is provided on the side of the main plate 404. One end of clamp B3 is fixedly connected to a fixing block 409. The side of fixing block 409 is fixedly connected to one end of clamp A1. The side of fixing block 409 is fixedly connected to a rotating sleeve 410. The inner circumferential surface of rotating sleeve 410 is rotatably connected to a rotating shaft 411. The two ends of rotating shaft 411 are fixedly connected to a main plate 412. The side of main plate 412 is fixedly connected to a spring 413. The side of spring 413 away from main plate 412 is fixedly connected to a clamping plate 414. The side of clamping plate 414 is fixedly connected to a limit post 415. The side of main plate 412 has a through hole 416.
[0036] In some examples, a protective sleeve 5 is fixedly connected to the side of clamp A1, and a protective sleeve 6 is fixedly connected to the side of clamp B3. The purpose of this is to increase the comfort of the operator's hands and improve the operator's work efficiency.
[0037] Two springs 405 are provided, and they are symmetrical about each other along the vertical central axis of the fixing block 401. Two springs 413 are provided, and they are symmetrical about each other along the vertical central axis of the fixing block 409. Their function is to improve the stability and balance of clamping the sample and prevent the sample from shifting or falling during the clamping process.
[0038] The circumferential surface of the limiting post 407 is slidably connected to the inner circumferential surface of the through hole 408, and the circumferential surface of the limiting post 415 is slidably connected to the inner circumferential surface of the through hole 416. Their function is to provide a limiting effect. Because the spring is flexible, this makes the clamping more stable.
[0039] There are two through holes 408 and 416, which are symmetrical about each other along the vertical central axis of the fixing block 401 and the fixing block 409. The side sections of the clamping plate 406 and the clamping plate 414 are set to be arc-shaped, which can better fit the surface of the sample when clamping the sample, thereby improving the stability and reliability of clamping.
[0040] For example, such as Figures 1-6 As shown, when it is necessary to clamp a sample in the hot pressing sintering furnace, the operator can hold clamps A1 and B3 and place the sample between clamping plate 406 and clamping plate 414. After the operator clamps the sample, the elastic action of springs 405 and 413 makes clamping plate 406 and clamping plate 414 firmly hold the sample. At this time, limiting post 407 and limiting post 415 slide in through hole 408 and through hole 416 respectively, which plays a role in limiting and stabilizing the clamping. Then, clamps A1 and B3 are lifted, and the sample is released. In addition, main plate 404 and main plate 412 are rotatably connected to fixing block 401 and fixing block 409 through rotating shaft 403 and rotating shaft 411, which can be flexibly adjusted to a vertical position, making it convenient for the operator to pick up and put down the sample.
[0041] like Figures 1-6As shown, this invention illustrates a sample handling fixture for a hot-pressing sintering furnace according to another embodiment of the present invention. A protective auxiliary device 7 is provided on the side of the main board 404. The protective auxiliary device 7 includes a connecting post 701, one end of which is fixedly connected to the side of the main board 404, and a protective plate 702 fixedly connected to the end of the connecting post 701 away from the main board 404. A fixing block is also present. A connecting post 703 is fixedly connected to the side of the main board 412, and a protective plate 704 is fixedly connected to the end of the connecting post 703 away from the main board 412. A perforated plate is fixedly connected to the side of the clamp A1. 705. A clamping plate 706 is fixedly connected to the side of clamp B3. A clamping post sleeve 707 is fixedly connected to the end of clamping plate 706 away from clamp B3. A clamping post 708 is slidably connected to the inner circumferential surface of clamping post sleeve 707. A pressure spring 709 is fixedly connected to the inner side of clamping post sleeve 707. An annular clamping plate 710 is fixedly connected to the end of pressure spring 709 away from clamping post sleeve 707. The side of an annular clamping plate 710 penetrates and is fixedly connected to the circumferential surface of clamping post 708. Its function is to protect the test sample from high temperatures when it is taken out, while also providing self-locking, thus enhancing the structural stability and safety of the entire clamp.
[0042] In some examples, the circumferential surface of the locking pin 708 is slidably connected to the top of the locking pin sleeve 707, and the pressure spring 709 is located inside the locking pin sleeve 707. Its function is to utilize the elasticity of the pressure spring 709 to enable the locking pin 708 to automatically reset.
[0043] The side of the perforated plate 705 has several through holes. The side of the perforated plate 705 is located on the displacement trajectory of the side of the annular clamping plate 710. Its function is to use the elasticity of the pressure spring 709 to ensure that the clamping post 708 can be clamped more tightly and more safely.
[0044] There are two connecting posts 701, which are symmetrical to each other along the central axis of the main board 404. There are two connecting posts 703, which are symmetrical to each other along the central axis of the main board 412. Their function is to enhance the structural stability of the entire protection, making the clamp more stable and reliable during use.
[0045] The side sections of the protective plate 702 and the protective plate 704 are set in an L shape. The circumferential surface of the clamping post 708 and the through hole on the side of the perforated plate 705 improve the connection stability, prevent the experimental object from slipping during the handling process, and further enhance the safety performance of the entire fixture.
[0046] For example, such as Figures 1-6As shown, the protective auxiliary device 7 further enhances the safety and practicality of the fixture. When the sample is removed from the hot-pressing sintering furnace, the protective plate 702 and the protective plate 704 effectively insulate against heat due to the high temperature of the sample, protecting the operator from burns. Simultaneously, the cooperation of the locking post 708 with the locking post sleeve 707 and the annular locking plate 710, with the locking post 708 inserted into the locking plate 706, achieves the self-locking function of the fixture, enhancing its structural stability and safety. When the locking post 708 is elastically engaged by the pressure spring 709 and tightly locked into the through hole of the perforated plate 705, the stability of the fixture when holding the sample is ensured.
