Description

Technical Field

[0001] The utility model relates to the technical field of sampling tools for a punching machine, in particular to a sampling device for a punching machine. Background Art

[0002] The punching machine uses hydraulic power to punch the required samples into small discs with a diameter of about 1 cm. The small discs fall directly into the innermost side of the airway below the punching platform. The equipment airway is generally set horizontally to connect the argon tube. After the sample preparation is completed, the argon gas is turned on, and the small sample pieces in the airway are blown out by the argon gas. However, there are often samples trapped in the inner side of the airway and cannot be blown out completely, causing problems such as sample confusion and missing. Therefore, it is necessary to remove the argon tube and switch to manual sampling. The samples are repeatedly taken out of the airway using a long stick and a medicine spoon. The operation is more troublesome. There is no special sample extraction tool, which is time-consuming and labor-intensive, and the work efficiency is low. If the long stick or medicine spoon used has a protrusion or a cutting edge, it is easy to damage the inner diameter of the airway or the sample when taking out the sample. The sample is easy to fall into the gap of the punching machine after being taken out. Utility Model Content

[0015] like Figure 1-Figure 4 As shown, the sampling device of the punching machine of the utility model includes a telescopic rod 1, a sponge head 2 and a fixed tube 3. The telescopic rod 1 is slidably connected in the fixed tube 3. The length of the telescopic rod 1 is greater than the length of the fixed tube 3. The front and rear ends of the telescopic rod 1 both extend out of the fixed tube 3. The sponge head 2 is fixedly connected to the front end of the telescopic rod 1.

[0016] When the utility model is in use, the telescopic rod 1 is first slidably inserted into the interior of the fixed tube 3, and the sponge head 2 is also located in the fixed tube 3. During operation, the telescopic rod 2 can be rotated to allow the sponge head 2 to smoothly enter the interior of the fixed tube 3. After ensuring that the sponge head 2 does not extend out of the fixed tube 3, the fixed tube 3 is inserted into the airway. At this time, the tail of the telescopic rod 1 is held to ensure that the telescopic rod 1 does not rotate, and then the fixed tube 3 is slowly rotated outwards to slowly expose the sponge head 2 inside the fixed tube 3, so that the sponge head 2 fills the innermost side. After the sponge head 2 is completely exposed, the fixed tube 3 is no longer rotated or slid, and then the telescopic rod 1 is slowly pulled outwards, and the sponge head 2 fills the sample inside the airway. All the samples are rubbed out because the sponge head 2 has filled the inner side of the airway. In this process, the sponge head 2 contacts the sample, and the surface and edge of the sample are not smooth, and there are small burrs. When the telescopic rod 1 is pulled outward, the sample in contact with the sponge head 2 is easily hung on the sponge head 2. At the same time, the sample becomes the force-bearing party because of the squeezing, and most of the external force is an outward drag force exerted by the sponge head 2. Therefore, this process can easily bring out all the samples. After pulling one end of the telescopic rod 1 outward a distance, the fixed tube 3 can be pulled outward, so that the telescopic rod 1 is continuously pulled to allow the sponge head 2 to enter the fixed tube 3 here.

[0017] To prevent the taken out samples from falling, the utility model has a sliding ring seat 4 slidably connected to the outer wall of the fixed tube 3, the sliding ring seat 4 is provided with a center hole 401, the center hole 401 is slidably connected to the outer wall of the fixed tube 3, a connecting column 5 is fixedly connected to the bottom of the sliding ring seat 4, and a sample tray box 6 is fixedly connected to one end of the connecting column 5 away from the sliding ring seat 4. When in use, the sliding ring seat 4 is operated to make the sample tray box 6 located below the air inlet, so that the taken out sample enters the sample tray box 6 after falling.

[0018] The top of the sliding ring seat 4 is provided with a screw hole 402, and a set screw 7 is connected in the screw hole 402, and the front end of the set screw 7 is connected to the outer wall of the fixed tube 3. The arrangement of the screw hole 402 and the set screw 7 enables the sliding ring seat 4 and the sample holder box 6 to slide and adjust their positions, which is convenient for use.

[0019] The sample tray box 6 is a rectangular box body with an open top surface; the side of the sample tray box 6 away from the connecting column 5 is open, and the opening on the side of the sample tray box 6 is connected to the side wall of the punch below the airway. The side of the sample tray box 6 away from the connecting column 5 is set as an opening so that the sample tray box 6 can be better connected to the side wall of the punch, making it more convenient for the sample to fall into the sample tray box 6, so that the sample will not collide with the side wall of the sample tray box 6 and bounce when it falls.

[0020] The present invention provides a special tool for taking out samples of a punching machine. Sampling is convenient and quick, and the working efficiency is high. The sample can be taken out from the airway of the equipment quickly and completely, and the sample can be prevented from being lost or falling into the gap of the equipment. The utility model is simple to manufacture, low in cost, and has promotion value.
