Description

Technical Field

[0001] This utility model belongs to the field of positioning mechanism technology, specifically a positioning mechanism for cutting columnar geological samples. Background Technology

[0002] A handheld columnar geological sample cutting and positioning mechanism is a portable device used to fix and position columnar geological samples for precise cutting. It is typically equipped with adjustable clamps and positioning components, allowing for stable clamping and position adjustment of the columnar sample through manual operation. During cutting, the mechanism ensures that the sample does not shift or shake, thus improving cutting accuracy and efficiency. Its applications are wide-ranging, primarily including geological exploration, mineral resource surveys, and geotechnical engineering. In these fields, researchers need to cut and analyze collected columnar geological samples to obtain information on the physical and chemical properties of rock strata; the handheld columnar geological sample cutting and positioning mechanism provides convenience and assurance for this process.

[0003] Existing positioning mechanisms for cutting columnar geological samples typically use a cable tie at one end of the placement tube to secure the sample. However, relying solely on locking one end can easily cause the sample to slip and shift during the cutting process, resulting in poor performance. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a positioning mechanism for cutting columnar geological samples, which effectively solves the problem that existing positioning mechanisms for cutting columnar geological samples usually fix the sample by setting a cable tie at one end of the placement tube, and relying solely on locking one end can easily cause the sample to slip and shift during the cutting process.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a positioning mechanism for cutting columnar geological samples, comprising a cutting machine body, a protective cover fixedly installed at one end of the cutting machine body, a cutting blade fixedly installed at the output end of the cutting machine body and installed inside the protective cover, a battery detachably installed at the other end of the cutting machine body, a connecting seat rotatably installed at one end of the protective cover via a hinge, a rotating frame fixedly installed at the bottom of the connecting seat, a placement cylinder rotatably installed in the middle of the rotating frame, two clamping hoops symmetrically arranged inside the placement cylinder, anti-slip pads fixedly installed on the sides of the two clamping hoops that are close to each other, a handle provided at one end of the placement cylinder, a transmission component provided at the lower part of the handle, the transmission component being connected to the two clamping hoops, and when the handle rotates, power is output to the two clamping hoops through the transmission component, so that the two clamping hoops clamp and fix the sample.

[0006] Preferably, the transmission assembly includes a support arm, which is fixedly installed on the lower part of the handle. A threaded sleeve is fixedly installed on the bottom of the support arm. An external thread is provided on one end surface of the placement cylinder. The threaded sleeve is threadedly connected to the surface of the placement cylinder through the external thread. A push cover is fixedly installed on one side of the threaded sleeve.

[0007] Preferably, the upper part and the lower part of the inside of the push cover are both closely attached to contact balls, and a squeezing plate is fixedly installed on the side of the two contact balls that are close to each other. A rectangular slide rod is fixedly installed on the side of the two squeezing plates that are close to each other.

[0008] Preferably, two rectangular grooves are symmetrically formed on the upper part and lower part of the middle of the surface of the placement cylinder. A rectangular sliding hole is formed in the middle of each of the two rectangular grooves. Two rectangular sliding rods are slidably installed inside the two rectangular sliding holes. A return spring is sleeved on the surface of each of the two rectangular sliding rods. The two ends of the two return springs are fixedly connected to the extrusion plate and the rectangular groove, respectively. The ends of the two rectangular sliding rods that are close to each other extend into the interior of the placement cylinder and are fixedly connected to the two clamping hoops, respectively.

[0009] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the operator inserts the columnar geological sample into the placement tube, and then the operator drives the support arm and threaded sleeve to rotate by gripping the handle. When the threaded sleeve rotates, the external thread will drive the push cover to move to one side of the cutting blade. When the push cover moves, it will push the two contact balls to move towards each other. When the two contact balls move towards each other, they will drive the rectangular slide rod to move towards each other along the inside of the rectangular slide hole through the extrusion plate. The two extrusion plates will also extrude the two return springs, thereby ensuring the stability of the movement of the two rectangular slide rods while giving them the ability to elastically return. When the two rectangular slide rods move towards each other, they will drive the two clamping hoops to move towards each other, thereby driving the two anti-slip pads to tightly clamp and position the columnar geological sample over a large area, preventing the sample from shifting and slipping.

[0010] The operator then starts the main body of the cutting machine, causing the cutting blade to rotate. The protective cover then causes the main body of the cutting machine to rotate along the connecting seat and hinge, so that the cutting blade comes into contact with the sample and phase to cut it. At the same time, the rotating frame causes the main body of the cutting machine and the cutting blade to rotate along the surface of the placement cylinder, thus completing the cutting of the sample from all directions. This allows the positioning mechanism for cutting columnar geological samples to stably clamp and fix the columnar geological samples over a large area, preventing sample displacement and slippage, and has a very good performance.

When the handle 9 rotates, the power is output to the two clamping hoops 8 through the transmission component, so that the two clamping hoops 8 clamp and fix the sample.

[0020] In use, the operator inserts the columnar geological sample into the placement cylinder 6. Then, the operator drives the transmission component by gripping the handle 9. When the transmission component is running, it causes the two clamping hoops 8 to move towards each other, thereby causing the two anti-slip pads 21 to tightly clamp and position the columnar geological sample over a large area, preventing the sample from shifting or slipping. Then, the operator starts the cutting machine body 1, causing the cutting blade 10 to rotate. Then, through the protective cover 5, the cutting machine body 1 rotates along the connecting seat 3 and hinge 4, so that the cutting blade 10 comes into contact with the sample and phase for cutting. At the same time, the rotating frame 2 causes the cutting machine body 1 and the cutting blade 10 to rotate along the surface of the placement cylinder 6, thereby completing the cutting of the sample from all directions.
