The positioning seat 133 is slidably connected to the base 134. The positioning screw 135 is rotatably connected to the base 134, in other words, the positioning screw 135 can only rotate relative to the base 134, and the positioning screw 135 cannot move axially relative to the base 134, specifically, as shown in fig. 4, the upper portion of the positioning screw 135 can be fittingly sleeved with a limiting sleeve 137 (it should be noted that only fig. 4 illustrates the limiting sleeve 137), the limiting sleeve 137 can be fixed to the positioning screw 135 by a set screw, the positioning screw 135 is formed with a shoulder which is connected to the base 134 in an abutting manner, the shoulder and the limiting sleeve 137 respectively abut against the upper and lower sides of the corresponding portion which sandwiches the base 134, and thus the positioning screw 135 cannot move along the axial direction of the positioning screw 135; in some embodiments, the upper portion of the positioning screw 135 and the corresponding portion of the base 134 may be connected by a bearing, in which case the shoulder is transformed into a butting connection with the lower end face of the inner race of the corresponding bearing. As shown in fig. 6 and 8, the positioning screw 135 is screwed with the positioning seat 133, the cutter wheel 131 is rotatably connected to one end of the connecting arm 132, and the other end of the connecting arm 132 corresponding to the positioning seat 133 is mounted and connected.

The working principle of the groove extruding mechanism of the utility model is briefly explained as follows: fig. 12 schematically shows an operation state in which the cutter wheel 131 machines the upper side surface of the heat sink base plate 98, and fig. 12 is a left side view, and a station feeding direction of the heat sink base plate 98 is an arrow direction in fig. 12.

Fig. 12 schematically illustrates the position of the saw blade 1111. As shown in fig. 1 and fig. 2, since the base 134 of the groove-extruding mechanism of the present invention is installed and connected with the groove-cutting insert device 1, so that in the process of moving and feeding the grooving insert device 1 leftwards, the knife wheel 131 is driven by the grooving insert device 1 to move and feed leftwards, as shown in fig. 12, so that the cutter wheel 131 can be pressed against the upper side of the heat sink base plate 98, and the machining depth of the cutter wheel 131 is adjusted by rotating the positioning screw 135, so that the cutter wheel 131 presses the upper side surface of the heat sink substrate 98 to form a pit on the heat sink substrate 98 (note that the cutting edge 1311 is not formed by cutting the heat sink substrate 98, so the pit is not formed by separating the material of the heat sink substrate 98), since the cutting edge 1311 is close to the clamping groove 981, the material of the walls of the clip groove 981 is forced to plastically deform and narrow the clip groove 981 so that the clip groove 981 clamps and secures the heat sink 99 in good contact. The height position of the cutter wheel 131 can be adjusted to adapt to the radiator base plates 98 with different thickness specifications by arranging the positioning screw 135 and combining with the lifting mechanism of the positioning seat 133. As shown in fig. 12, in order that the cutter wheel 131 does not touch the heat sink 99, the distance between the cutting edge 1311 of the cutter wheel 131 and the saw blade 1111 in the direction of the arrow in fig. 12 should be smaller than the pitch of the heat sink 99 inserted into the heat sink substrate 98, and in order that the cutter wheel 131 can press the upper side of the heat sink substrate 98 beside the corresponding clip groove 981, the cutting edge 1311 of the cutter wheel 131 should be disposed at the front position of the saw blade 1111 in the station feeding direction of the heat sink substrate 98. From the foregoing, because the utility model discloses an extrusion groove mechanism can process the last side of extrusion radiator base plate 98 at grooving inserted sheet device 1's the in-process of feeding, so on grooving inserted sheet radiator preparation equipment original moving mechanism's basis, realized simply that the double-layered groove 981 plastic deformation centre gripping fixed cooling fin 99 that makes radiator base plate 98 compares with the mode of the last side of the staff combination hand tool of passing through of prior art chiseling radiator base plate 98 on the next door of double-layered groove 981, the utility model discloses an extrusion groove mechanism is favorable to improving work efficiency, is favorable to reducing intensity of labour.
