Further, one side of the fixed block, which is far away from the sliding block, is provided with a handle.
Further, all be equipped with the through-hole on fixed block and the sliding block to and the hinge point department at rhombus frame both ends, the bolt passes behind the through-hole and locks rhombus frame and fixed block and sliding block through nut and gasket.
Further, be equipped with the horizon bar between fixed block and the sliding block, horizon bar one end and fixed block fixed connection, sliding block slidable installs on the horizon bar.
Further, the horizontal rods comprise two round rods which are arranged in parallel.
Further, the rhombus frame is articulated each other by V-arrangement connecting rod and X-shaped connecting rod and forms, and wherein the V-arrangement connecting rod is articulated to be constituted by two connecting rod one ends, and the X-shaped connecting rod is articulated to be constituted by two connecting rod middle parts, the V-arrangement connecting rod includes two, is located fixed block and sliding block respectively, and the X-arrangement connecting rod includes a plurality ofly, articulates back both ends in proper order and then hinges with two V-arrangement connecting rods respectively.
The invention has the beneficial effects that: the diamond-shaped frame with the adjustable opening size is used for clamping samples, so that the samples with different model sizes can be stably clamped, meanwhile, the damage to the human body and the waste of materials caused by manual grinding can be avoided, the clamping grinding of a plurality of samples can be carried out simultaneously, the working efficiency is greatly improved, and the clamp can be folded to be folded and retracted, and is convenient and fast to use.
Drawings
FIG. 1 is a schematic diagram of the present invention.
Marked in the figure as 1-diamond frame, 2-fixed block, 3-sliding block, 4-antiskid rubber mat, 5-handle, 6-through hole, 7-horizontal rod, 11-V-shaped connecting rod and 12-X-shaped connecting rod.
Detailed Description
The invention is further described below with reference to the accompanying drawings.
As shown in fig. 1, the metallographic specimen grinding fixture comprises a rhombic frame 1 formed by hinging a plurality of connecting rods, wherein a fixed block 2 and a sliding block 3 are respectively arranged at the hinging parts at two ends of the rhombic frame 1, and the fixed block 2 and the sliding block 3 can lock the hinging points at two ends of the rhombic frame 1 through bolts and nuts.
The using process of the invention is as follows: firstly, the connection between the fixed block 2 and the sliding block 3 and the diamond-shaped frame 1 is loosened to open the middle cavity of the diamond-shaped frame 1, then a sample to be ground is placed in the middle cavity of the diamond-shaped frame 1, then the fixed block 2 and the sliding block 3 are pulled to reduce the middle cavity of the diamond-shaped frame 1 until the sample is clamped, and finally the fixed block 2 and the sliding block 3 are locked to prevent the diamond-shaped frame 1 from moving again to clamp the sample. After the grinding clamp is clamped, a sample can be held more stably, so that the grinding work efficiency and quality are improved.
In order to better clamp a sample, an anti-skid rubber pad 4 is arranged on the inner side wall of the diamond-shaped frame 1. The anti-skid rubber mat 4 can increase the friction force between the diamond-shaped frame 1 and a test sample, thereby improving the clamping force of the diamond-shaped frame 1.
For better holding the clamp, a handle 5 is arranged on one side of the fixed block 2 far away from the sliding block 3. When the sample is ground, the handle 5 is directly held by a hand, so that the hand is far away from the sample, and fingers can be prevented from being injured.
To specific locking mode, this application is in on fixed block 2 and the sliding block 3 to and the articulated point department at 1 both ends of rhombus frame all is equipped with through-hole 6, the bolt passes behind the through-hole 6 and locks rhombus frame 1 and fixed block 2 and sliding block 3 through nut and gasket.
Further, be equipped with horizon bar 7 between fixed block 2 and the sliding block 3, horizon bar 7 one end and fixed block 2 fixed connection, sliding block 3 slidable installs on horizon bar 7. The horizontal rod 7 is arranged to play a certain auxiliary stabilizing role, so that the rocking and deformation of the rhombic frame 1 can be avoided, and the integral structural strength is improved. To avoid twisting of the rhomboid frame 1, the horizontal bars 7 are preferably two round bars arranged in parallel.
In order to carry out the centre gripping to a plurality of samples simultaneously and grind, but this application has adopted the structural style that splices. Specifically, the rhombic frame 1 is formed by mutually hinging a V-shaped connecting rod 11 and an X-shaped connecting rod 12, wherein the V-shaped connecting rod 11 is formed by hinging one ends of two connecting rods, the X-shaped connecting rod 12 is formed by hinging the middle parts of the two connecting rods, the two V-shaped connecting rods 11 are respectively positioned on the fixed block 2 and the sliding block 3, the X-shaped connecting rods 12 comprise a plurality of X-shaped connecting rods 12, the X-shaped connecting rods 12 in specific number can be selected according to actual needs to be spliced, and then the two spliced ends are respectively hinged with the two V-shaped connecting rods 11.
The diamond-shaped frame with the adjustable opening size is used for clamping samples, so that the samples with different models and sizes can be stably clamped, the damage to a human body and the waste of materials caused by manual grinding can be avoided, the number of the diamond-shaped frames can be flexibly adjusted according to the number of the samples, the clamping and grinding of a plurality of samples can be simultaneously realized, the working efficiency is greatly improved, the clamp can be folded and unfolded, the use is convenient and rapid, and the diamond-shaped frame type grinding machine has good practicability and application prospect.
