In one embodiment, as shown in fig. 4 and 8, the first block 10 is provided with a first avoidance groove 102 on a side facing the wedge block 20, the second block 30 is provided with a second avoidance groove 302 on a side facing the wedge block 20, and bottom surfaces of the first avoidance groove 102 and the second avoidance groove 302 are flat; the two ends of the first fixing member 70 are respectively provided with a step, the end surface of the step at one end of the first fixing member 70 can be abutted against the bottom surface of the first avoidance groove 102, the axis of the first fixing member 70 is perpendicular to the bottom surface of the first avoidance groove 102, and/or the end surface of the step at the other end of the first fixing member 70 can be abutted against the bottom surface of the second avoidance groove 302, and the axis of the first fixing member 70 is perpendicular to the bottom surface of the second avoidance groove 302. The first avoiding groove 102 and the second avoiding groove 302 are arranged on the inclined surfaces of the first cushion block 10 and the second cushion block 30 to avoid the step of the first fixing member 70, so as to ensure that the inclined surfaces of the first cushion block 10 and the second cushion block 30 can be attached to two side surfaces of the wedge block 20. In this embodiment, the bottom surfaces of the first avoiding groove 102 and the second avoiding groove 302 are set to be flat surfaces, and the end surfaces of the steps at the two ends of the first fixing member 70 abut against the bottoms of the first avoiding groove 102 and the second avoiding groove 302, so that the reliability of the relative fixation between the first fixing member 70 and the first cushion block 10 and the second cushion block 30 can be improved, and the wedge block 20 can be moved more stably and reliably through the transmission rod 601. In this embodiment, the first avoiding groove 102 is disposed at an end of the first accommodating groove 101, and a bottom surface of the first avoiding groove 102 is parallel to a side surface of the first cushion block 10 departing from the wedge block 20; the corresponding second avoiding groove 302 is disposed at an end of the second accommodating groove 301, and a bottom surface of the second avoiding groove 302 is parallel to a side surface of the second cushion block 30 departing from the wedge block 20. The arrangement of the axis of the first fixing member 70 perpendicular to the bottom surface of the first avoiding groove 102 and/or the bottom surface of the second avoiding groove 302 simplifies the structure of each component and makes the height adjustment process of the whole machine tool block more stable and reliable.

In one embodiment, as shown in fig. 7, the wedge block 20 is further provided with a plurality of weight-reducing grooves 204 at positions avoiding the sliding groove 201, the first guide groove 202 and the second guide groove 203. A plurality of weight-reducing slots 204 are formed in the wedge block 20 to reduce the weight of the wedge block 20, so that the wedge block 20 can be moved more easily, thereby saving labor. The structural form of the lightening groove 204 is not limited as long as the structural strength of the entire wedge block 20 is not affected and the other guide grooves of the slide groove 201 and the like are not affected.

In one embodiment, as shown in fig. 1, the machine tool head block further comprises a damping member 90, the damping member 90 being fixed to a surface of the first head block 10 facing away from the wedge block 20. The damper 90 is bonded to the first block 10. In this embodiment, the damping member 90 is a rubber mat, the structure of the mat is consistent with the upper surface of the first mat 10, and the mat is adhered to the first mat 10 by glue. The vibration damping member 90 made of rubber can further absorb the vibration of the machine tool, and can also play a role in skid resistance.

The application provides an assembly and use of lathe cushion as follows:

fixing the second guide 50 on the second cushion block 30, placing the wedge block 20 on the inclined surface of the second cushion block 30, and attaching the inclined surface of the wedge block 20 and the inclined surface of the second cushion block 30, at this time, the second guide 50 extends into the second guide groove 203 on the wedge block 20. One end of the first fixing member 70 is inserted into the second receiving groove 301 of the second block 30. The transmission rod 601 is inserted into the through hole at the end of the wedge-shaped block 20, the second fixing member 602 (including the washer 6022 and the nut 6021) is connected with the transmission rod 601, then the transmission portion 6013 of the transmission rod 601 is screwed with the screw hole 701 of the first fixing member 70, and the second fixing member 602 is installed in place by screwing the transmission rod 601 so that the limiting surface 6011a of the driving portion 6011 of the transmission rod 601 abuts against the end surface of the wedge-shaped block 20. The two retaining members 80 are then connected to the transmission rod 601. The first guide member 40 is fixed to the first block 10, then the other end of the first fixing member 70 is aligned with the first receiving groove 101, the first guide member 40 is aligned to the position of the first guide groove 202, and then the inclined surface of the first block 10 is fitted to the side surface of the wedge block 20. By rotating the transmission rod 601 clockwise or counterclockwise, the wedge 20 is moved along with the movement of the transmission rod 601, and the height of the machine tool block is changed.
