The slider 500 is slidably connected to the horizontal rail 400.
The first driving mechanism is connected to the slider 500 to drive the slider 500 to move left and right along a track defined by the horizontal rail 400 between a position near the left end face of the handpiece and a position far from the left end face of the handpiece. Advantageously, the first driving mechanism includes a first motor 610 and a first ball screw 620,6, the first motor 610 is provided on the body 100, one end of the first ball screw 620 is connected to the first motor 610, the other end of the first ball screw 620 is connected to the body 100, and a nut of the first ball screw 620 is connected to the slider 500.
The operation of the horizontal brinell hardness tester according to an embodiment of the present invention is briefly described as follows.
As shown in fig. 1, the workpiece is placed on the working platform 200, the first motor 610 drives the first ball screw 620 to rotate, the nut of the first ball screw 620 moves rightward on the first ball screw 620, and drives the slider 500, and the slider 500 pushes the right end surface of the workpiece rightward against the left end surface of the machine head. In other words, the slider 500 and the head function as a clamp for clamping the object to be measured. The second driving mechanism 330 drives the pressing head 320 leftwards and extends out of the left end face of the machine head so as to detect the hardness of the tested piece. After the detection is completed, the second driving mechanism 330 drives the pressing head 320 to the right to retract into the left end face of the machine head, and the first motor 610 reverses to enable the sliding block 500 to move leftwards to be far away from the left end face of the machine head, so that the detected piece is taken away.
