The technical solution adopted by the utility model is: a tool clamping device for a CNC boring and milling machine, including a tool handle body and a clamping part. The tool handle adopts a standard tapered tool handle structure, and the front large end surface is fixedly connected to the clamping part. , the clamping part is a square strip structure, and there is a connected groove between the two ends of the strip, which is perpendicular to the length direction of the handle body and faces the opposite direction of the handle body, and the side wall of the groove is provided with a lock Tighten the screw, put the turning tool into the groove, adjust it to a proper position, and tighten the locking screw to realize the use of the boring and milling cutter.

Preferably, there are three locking screws, which can hold the tool more firmly, have higher reliability, and ensure machining accuracy.

Preferably, screw holes are provided on both side walls of the above-mentioned groove, so as to ensure that the tool is tightened through the screw hole at the other end after the tool is reversed, and the operation is more convenient.

A tool clamping device for a CNC boring and milling machine also includes a spacer for clinging to the tool, which is arranged at the place where the locking screw contacts the tool, and contacts the surface of the tool through the spacer, which increases the contact area, the friction force is greater, and the tool is more firm Reliable, better guarantee the machining accuracy, and can effectively protect the tool surface from being damaged due to stress concentration.

Preferably, the symmetry plane in the length direction of the groove coincides with the axis of the tapered part of the tool handle body, so as to reduce the serious wear of the tool caused by tool deviation and benefit the service life of the tool.

Preferably, the handle body and the clamping portion are fixedly connected by welding, so that the connection is more reliable and the manufacture is more convenient.

Beneficial effects of the utility model: Compared with the prior art, the utility model adopts the tool clamping part provided on the large end surface of the standard tool, puts the tool into the groove of the clamping part, and adjusts it to a suitable position, and then it can Realize boring and milling processing, which effectively solves the problems of difficult, expensive, inapplicable and large amount of knives in the workshop. This structure has the advantages of convenient loading and unloading, high reliability, good use effect and condition, and can be realized by locking screws. The tool length is adjustable, the processing range is wider, and it has the characteristics of simple structure and strong applicability, which greatly saves the production cost.

Detailed ways

As shown in Figures 1 to 4, a tool clamping device for a CNC boring and milling machine includes a tool handle body 1 and a clamping part 2. The tool handle 1 adopts a standard tapered tool handle structure, and the front large end surface is fixedly connected and clamped. Part 2, the clamping part 2 is a square strip structure, and there is a connected groove 6 between the two ends of the strip, which is perpendicular to the length direction of the handle body 1, facing the opposite direction of the handle body 1, and on the side wall of the groove 6 There is a locking screw 4, put the turning tool into the groove 6, adjust it to a suitable position, tighten the locking screw 4, and the use of the boring and milling cutter can be realized. The tool clamping part, put the tool into the groove of the clamping part, adjust it to a suitable position, and then the boring and milling process can be realized, which effectively solves the difficulty of buying knives in the workshop, the cost of buying knives, the inapplicability of buying knives and the large amount of knives consumed The structure has the characteristics of convenient loading and unloading, high reliability, good use effect and condition, adjustable tool length through locking screws, wider processing range, and simple structure, which greatly saves production costs.

Preferably, the above-mentioned locking screws 4 are provided with three, which can hold the tool more firmly, have higher reliability, and ensure machining accuracy; the two side walls of the above-mentioned groove 6 are provided with screw holes to ensure that the tool 3 can pass through after reversing. The screw hole at the other end tightens the tool, which makes the operation more convenient; the symmetry plane in the length direction of the above-mentioned groove 6 coincides with the axis of the taper part of the tool handle body 1, which reduces the serious wear of the tool 3 caused by the deviation of the tool 3 and is beneficial to the service life of the tool ; The handle body 1 and the clamping portion 2 are fixedly connected by welding, the connection is more reliable, and the manufacture is more convenient.
