The knife block mounting plate is fixed on the side of the knife bar by the knife bar splint bolt, and the top of the knife block mounting plate A sinking pressure plate limit groove is formed relative to the knife rod and the knife bar splint, and the positioning mounting boss on the inner side of the pressure plate is correspondingly snapped into the pressure plate limit groove, and the knife block is fixed and clamped to the limit knife block on the top edge of the knife block mounting plate. The rigidity of the front end of the positioning mounting boss of the pressure plate acts on the rear end of the knife block on the full-length limiting groove. The technical scheme of the knife block assembly is rigid, the assembly accuracy is maintained for a long time, and the normal service life is prolonged, and the length of the knife block mounting plate fully meets the required regrinding feed after the knife block is worn, which greatly reduces the consumption of processing costs.

Description

Assembled Machine Clamp Grooving Knife Holder

technical field

The utility model relates to a turning and grooving tool handle of a machine tool, which is used for clamping a cutting tool block.

Background technique

The grooving knife is the tool with the highest damage rate in machine tool processing. As shown in Figure 1 to Figure 3, the knife block and the knife handle are connected by contact, and there are many parts and complex assembly. The knife block 2 is positioned on the positioning groove of the knife block mounting plate 1', the knife block mounting plate 1' is fixed in the notch at the front end of the knife bar 7' by bolts, and the upper part of the knife block 2 is fixed on the pressure plate 3' of the knife bar by one end. Press, the cutter block rear portion is pressed by the adjusting bolt 4 that is threaded on the adjusting mounting block 5. It can be seen that the existing structure of the grooving knife handle has the technical problem of poor rigidity of the knife block installation. The pressure plate is only fixed by bolts. During the process of applying force, the phenomenon of clamping shifting and loosening is easy to occur, and the assembly accuracy cannot be maintained for a long time. The installation stiffness of the knife block is affected by the assembly clearance and the thread fit accuracy of the adjusting bolt, which is the main source of damage to the grooving knife, and the length of the knife block mounting plate is limited, and the damage of the knife block will cause serious damage to the knife block mounting plate and the knife rod , can not be re-sharpened, only the whole set of tool handle can be scrapped, the service life is extremely short, the processing consumption is large, and the cost is high.

Contents of the invention

The purpose of the invention of the present utility model is to provide an assembled machine clip grooving knife handle with high rigidity for knife block assembly and regrinding for continuous use. The utility model provides the technical scheme of the assembled machine clip grooving knife handle, and its main technical content is: an assembled machine clip grooving knife handle, which consists of a knife block, a knife block mounting plate, a knife rod and a pressure plate, The knife block mounting plate is fixed on the side of the knife bar by bolts of the knife bar splint, and the part extending from the front end relative to the knife bar is used as the knife block mounting section. The rod and the tool bar splint form a sinking pressure plate limit groove. The pressure plate is fixed on the knife bar. The positioning installation boss on the inner side of the pressure plate is correspondingly snapped into the pressure plate limit groove, and the knife block is fixed and clamped on the top edge of the knife block mounting plate. On the limited groove of the full length of the limited knife block, the rigidity of the front end of the positioning mounting boss of the pressing plate acts on the rear end of the knife block.

The utility model discloses the technical scheme of the assembled machine clip grooving knife handle, the limit groove of the clamping pressure plate formed by the knife block mounting plate between the knife rod and the knife rod splint, ensures that the fixing state of the pressure plate is stable, long-lasting, and does not slip It not only provides a reliable rigid back end for the knife block, but also enhances the stability and reliability of the clamping of the knife block, ensures the rigidity of the knife block assembly, maintains the assembly accuracy for a long time, and prolongs the normal service life. Another great advantage of this technical solution is that it overcomes the technical defect that the entire set of tool handles cannot be reground. The length of the knife block mounting plate fully meets the required regrinding feed after the knife block is worn, which increases the continuous use of the entire set of tool handles. Time, can greatly reduce the consumption of processing costs.

Detailed ways

The utility model discloses an assembled machine clip grooving knife handle, which consists of a knife block 2, a knife block mounting plate 1, a knife bar 7, a knife bar splint 6 and a pressure plate 3, and the knife bar 7 is a square fixed base , its side is shaped with a number of screw holes for fixing the knife block mounting plate 1 and the knife bar splint 6, the knife block mounting plate 1 is fixed on the side of the knife bar 7 by bolts of the outer knife bar splint 6, and the knife block mounting plate 1 is fixed on the knife bar 7 Between it and the knife bar clamping plate 6, a sinking pressure plate limit groove 11 is formed on the top, and the pressure plate 3 is fixed on the upper plane of the knife bar 7, and the inner side of the pressure plate 3 is provided with a positioning installation boss 30, which is compatible with the described positioning installation boss 30. The position of the pressure plate limit groove 11 is corresponding, so that the pressure plate 3 is accurately and firmly fixed and limited, so that the firm pressing end of the pressure plate 3 acts on the knife block 2. In this implementation structure, the outside of the pressure plate 3 is also provided with Clamping plate hook edge 31, to further enhance the stability of the pressing plate 3 and the fixing of the knife bar clamping plate 6.

The part extending from the front end of the knife block mounting plate 1 relative to the knife bar 7 is used as the fixed clamping section of the knife block 2. The top edge of the knife block mounting plate 1 is shaped with a long V-shaped limiting groove 10, and the bottom of the knife block 2 is connected to the The V-shaped limiting groove fits the limit, and is clamped and fixed on the knife block mounting plate 1 by the pressure plate 3, and the front end of the positioning installation convex 30 of the pressure plate 3 acts rigidly on the knife block 2 rear end.

The fixed bolt interval length of the cutter block mounting plate 1 is the regrinding feed rate. When the cutter block 2 is worn to a certain extent, the cutter block mounting plate 1 moves forward for a fixed bolt interval feeding amount, and the rear part is installed or replaced with a fixed top plate 4 of the corresponding size, and then ground according to the cutting amount of the cutter block 2 The excess part of the knife block 2 and the knife block mounting plate 1 is reused. The knife block mounting plate 1 is rigidly limited by the top plate 4 to ensure the position of the knife block mounting plate 1 and not to move when it is stressed during processing.
