Technical Field

The utility model relates to a metallography is ground and is thrown technical field, concretely relates to metallography is ground and is thrown quick-witted sample fixing device.

Background

The metallographic specimen grinding and polishing machine is an economic machine type which combines specimen pre-grinding and polishing operations into a whole, and the turntable obtains different rotating speeds through the rotating speed ratio of the belt wheel, so that the grinding and polishing function is realized, and the metallographic specimen grinding and polishing machine is ideal equipment for manufacturing specimens of small and medium-sized enterprises. Meanwhile, the device is one of indispensable devices for preparing samples in a laboratory.

The existing common metallographic grinding and polishing machine has the following characteristics:

the first disk and the second disk are pre-grinding disks and polishing disks respectively. Thereby realizing two requirements of pre-grinding and polishing by one machine;

secondly, during pre-grinding, cooling water is continuously injected into the rotating grinding disc through the rotary water nozzle, and manual water injection is not needed to realize cooling of the device;

and thirdly, the sand paper can be tightly attached to the grinding disc under the action of atmospheric pressure, so that the sand paper does not need to be bonded or clamped. During polishing, the polishing fabric can be flatly laid on the polishing disc, then the fabric is fastened by the fastening ring, and then polishing is carried out, so that the fabric and the polishing disc can be replaced timely and conveniently.

In actual operation, a common grinding and polishing machine sample in a laboratory is manually held, the wheel disc is inevitably touched when the sample is held by hands, and the rotating speed of the wheel disc is too high, so that fingers of an operator are easily abraded.

Disclosure of Invention

The utility model aims at overcoming not enough among the prior art, providing a throw sample fixing device in addition on the metallography machine of throwing that grinds, sample can be fixed to this device, for the operator provides convenience and guarantees operator's safety, compensatied not enough of ordinary mill machine of throwing.

In order to solve the technical problem, the utility model discloses a realize through following technical scheme:

the utility model provides a metallography grinding and polishing machine sample fixing device, includes handheld pole, fixed frame, adjustable supporting rod and grip block, and wherein handheld pole is the T font, including horizon bar and vertical pole, vertical pole is located horizon bar length direction's central point and puts, and the operator is handheld at the both ends of horizon bar, and the lower extreme of vertical pole links firmly on fixed frame's top, and fixed frame's bottom is rotated and is connected a plurality of adjustable supporting rods, and the one end of adjustable supporting rod links firmly the grip block.

Preferably, the adjustable clamping rod is a screw rod and is in threaded connection with the bottom end of the fixed frame.

Further, fixed frame includes two square boards, four prisms and four trapezoidal boards, and four prismatic vertical settings are between two square boards, and are located the four corners of two square boards respectively, and four prisms are perpendicular with two square boards, have linked firmly four trapezoidal boards on the bottom surface of the square board that is located the below, and four trapezoidal boards are located four sides of square board respectively. The fixing frame is used for clamping and fixing the sample and is also used for fixing the handheld rod, the handheld rod is well connected with the sample, and the design structure is strong in stability, simple in design and convenient to process.

Further, a screw rod is connected to each trapezoidal plate in a threaded mode. The screw rod has simple structure and convenient use.

Preferably, a screw is threadedly connected to the square plate located below. One end of the screw rod is fixedly provided with a clamping plate, the screw rod is rotated to move the clamping plate to a sample, and the sample is fixedly clamped in the fixed frame by one clamping plate at the top of the sample and four clamping plates around the sample.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model discloses can fix and treat the mill and throw the sample, solve the manual work and held the sample and grind the inconvenience of throwing, can guarantee operator's safe in utilization to a certain extent. The utility model discloses well adjustable screw rod and fixed frame can be used for matcing not unidimensional sample, and the suitability is wide. Meanwhile, compared with the existing full-automatic grinding and polishing machine, the clamp is cheap and easy to obtain and is easy to popularize.
