Description

Technical Field

[0001] The utility model relates to the technical field of lifting equipment, in particular to a sample lifting structure used in conjunction with a heating table. Background Art

[0002] The sample is placed on a heating table and heat-treated as needed, but the sample needs to be cooled to room temperature before it can be taken out and placed, which is time-consuming and inefficient. When the sample is in contact with the heating table, it is difficult to take and place the sample, and the sample may be damaged.

[0003] After searching, Chinese patent CN214495558U was found and announced, which disclosed a heater lifting device. By setting a limit platform between the bottom plate and the lifting platform and limiting the moving range of the lifting platform through the limit platform, the lifting platform is prevented from colliding with the bottom equipment and causing damage to the equipment, thereby improving the safety of the equipment. This patent starts the drive motor to drive the lead screw to rotate forward and reverse, so that the lifting platform can be lifted and lowered under the vertical guidance of the guide rod. However, this patent realizes the up and down movement through the rotation of a lead screw, and there is only one support point for driving the movement of the lifting platform, which can easily cause the lifting platform area away from the lead screw to shift, thereby affecting the balance during the lifting process. In view of this, a sample lifting structure for use with a matching heating platform is proposed. Utility Model Content

The cover plate 4 is interspersed with mounting screws threadedly connected to the protective frame 3. The cover plate 4 can be disassembled and assembled. A mounting plate 5 is fixedly installed on the top of the fixed plate 1 and on the outside of the protective frame 3.

[0020] See also Figure 1-3 A lifting assembly 6 for lifting the sample 2 is provided on the mounting plate 5. The lifting assembly 6 includes a movable shaft 61, a servo motor 62, a cam body 63, a bevel gear 64, a push rod 65, a heating platform body 66 and a push pin 67. The movable shaft 61 is rotatably connected to the mounting plate 5. The movable shaft 61 is rotatably connected to the protective frame 3. The protective frame 3 can support the movable shaft 61. The servo motor 62 is fixedly mounted on the outer surface of the mounting plate 5. The output shaft of the servo motor 62 is fixedly mounted on the movable shaft 61. When the servo motor 62 is started, the movable shaft 61 rotates, and the lifting and lowering work is gradually performed.

[0021] In addition, the cam body 63 is fixedly mounted on the outer surface of the movable shaft 61, and the cam body 63 can rotate with the movable shaft 61. The bevel gear 64 is fixedly mounted on the tail of the movable shaft 61. The rotation of the movable shaft 61 can drive the bevel gear 64 to rotate. The bevel gear 64 is located in the protective frame 3. The bevel gears 64 and the bevel gears 64 are meshed with each other. Under the mutual meshing of the bevel gears 64, multiple movable shafts 61 can be driven to rotate together. The push rod 65 is arranged on the outer surface of the cam body 63, and the tail of the push rod 65 is connected to the cam body The outer surfaces of 63 are in contact with each other, and the rotation of the cam body 63 can push the push rod 65 to move upward. The number of the movable shaft 61, the cam body 63, the bevel gear 64 and the push rod 65 are all four. The heating platform 66 is fixedly installed on the top of the push rod 65, and the ejector pin 67 is fixedly installed on the top of the heating platform 66. The sample 2 is placed on the ejector pin 67. The heating platform 66 and the ejector pin 67 can be lifted and lowered under the drive of the ejector pin 65, thereby realizing the lifting and lowering of the sample 2. The heating platform 66 does not need to stop working, thereby improving the overall work efficiency.

[0022] See also Figure 3 A guide assembly 7 is provided on the cam body 63, and the guide assembly 7 includes a cam plate 71, a cam groove 72 and a connecting column 73. The cam plate 71 is fixedly mounted on both ends of the cam body 63, and the cam plate 71 is fixedly mounted on the movable shaft 61. The cam plate 71 can rotate following the movable shaft 61. The cam groove 72 is provided on the cam plate 71 and corresponds to the cam body 63. The cam groove 72 can rotate following the cam plate 71. The connecting column 73 is fixedly mounted on both ends of the ejector rod 65 and extends into the inner wall of the cam groove 72. The connecting column 73 is movably connected to the inner wall of the cam groove 72. Because the connecting column 73 extends into the cam groove 72, when the cam plate 71 moves, it will force the ejector pin 67 to move up and down.

[0023] See also Figure 1-3 A guide assembly 8 is provided between the fixed plate 1 and the heating platform 66. The guide assembly 8 includes a sleeve 81 and an optical axis 82. The sleeve 81 is fixedly mounted on the top of the fixed plate 1 and is located on the outside of the protective frame 3 and the mounting plate 5. The optical axis 82 is fixedly mounted on the bottom of the heating platform 66 and is located on the outside of the ejector 65. The optical axis 82 is slidably connected in the sleeve 81. Under the vertical cooperation and guidance of the sleeve 81 and the optical axis 82, the heating platform 66 and the ejector pin 67 can only move vertically up and down and will not move in other directions.

[0024] When this embodiment is in use, the servo motor 62 is started, and under the mutual meshing transmission of the bevel gears 64, the multiple movable shafts 61 rotate together, driving the multiple cam bodies 63 to rotate together, gradually pushing the ejector rod 65 to move upward or fall due to gravity, so that the heating platform 66 and the ejector pin 67 rise and fall accordingly, thereby realizing the lifting function of the sample 2.

[0025] The beneficial effects of the above embodiments are:

[0026] The sample lifting structure used in conjunction with the heating table is provided with a lifting component 6. After use, the lifting component 6 can be meshed with multiple bevel gears 64. When one of the movable shafts 61 rotates, the remaining movable shafts 61 are driven to rotate together, so that the multiple cam bodies 63 rotate accordingly, and then the push rods 65 are lifted or dropped, so that the heating table body 66 and the push pin 67 can perform lifting and lowering movements. Since the heating table body 66 is lifted by the multiple push rods 65, the stability during the lifting process is guaranteed, and the heating table body 66 is avoided from deflecting during the lifting process as much as possible. The cam body 63 only needs to rotate half a circle to completely lift the heating table body 66, thereby ensuring the lifting speed, realizing rapid cooling of the sample 2, and the heating table body 66 does not need to stop working, thereby improving the overall work efficiency. When the sample 2 is lifted, there is a certain space between the sample 2 and the heating table body 66, which is convenient for the operator to take and put the sample 2.

[0027] In addition, by setting the guide component 7, the guide component 7 can make the connecting column 73 always located in the cam groove 72 on the cam plate 71 after use, and the connecting column 73 is fixedly installed with the push rod 65. When the cam body 63 rotates, the push rod 65 can be pulled, thereby avoiding the heating platform 66 from being stuck during the movement process as much as possible, and ensuring the smoothness of the heating platform 66 during the lifting and lowering process.
