Description

CNC machine tool holder

This creation relates to the adjustment elements mounted on the turret of the processing machine, in particular to a tool holder design that can fine-tune the tool hole in the Y-axis direction to align the tool to the cutting position of the workpiece.

Referring to FIG. 1 and FIG. 2, according to the conventional CNC machining machine, when machining the surface of the workpiece a, the inner hole or the outer diameter of the workpiece a, the workpiece a must be first clamped on the chuck 1 of the processing machine, and the workpiece a is The center of the chuck 1 is the same as the center of the chuck 1 , and if the length of the workpiece a is long and the surface of the workpiece a is to be machined to a predetermined size, the force of the turning tool 5 on the workpiece a is required to be laterally pushed. The clamping of the workpiece a can achieve the preset precision and safety problems of the workpiece a, so the ejector pin 3 of the tailstock 2 of the processing machine needs to be placed on the end surface of the workpiece a, so that the workpiece a is clamped. The rotation of the head 1 is rotated together to facilitate the surface machining of the turning tool 5 on the processing machine turret 4 close to the workpiece a.

Referring to FIG. 3 to FIG. 5, since the ejector pin 3 of the CNC machine is placed at the end of the workpiece a, a counterbore b must be machined on the end face of the workpiece a with the center drill 5a to match the tapered shape of the thimble 3. And the top is in the counterbore b. Further, one end of the workpiece a is clamped by the chuck 1 of the processing machine, and then the other turning tool 5 is used to machine a plane on the end surface of the workpiece a as shown in Fig. 1, and then the end of the workpiece a is drilled by the center drill 5a. Surface processing b, the counterbore b is provided to the top pin 3 of the processing machine tailstock 2 to be close to the top, so that the center of the collet 1 and the counterbore b are on the same axis, so as to fit the collet 1 to clamp the workpiece a in both directions.

Referring to FIG. 5 and FIG. 8 together, the conventional center drill 5a is mounted on a fixing seat 9 of the turret 4, and after the counterbore b is machined to the workpiece a, the turret 4 is rotated by an angle to cut the outer diameter of the cutter. When the turning tool 5 cuts the outer diameter of the workpiece a as shown in Fig. 1, the ejector pin 3 of the tailstock 2 of the processing machine needs to protrude against the counterbore b, and the protruding length A1 of the thimble 3 exceeds the width B1 of the fixing seat 9 plus The upper center drill 5a protrudes from the length C1 of the fixing seat 9 to contact the counterbore b of the workpiece a, otherwise the workpiece a will not be reached, and the tailstock 2 of the processing machine is moved at this time, but the tailstock is moved by the tailstock 2 The backing of the chuck 1 is very time consuming and troublesome, and the tailstock 2 slips on the guide rail 6 of the processing machine base 7 with a slight error, which directly affects the accuracy of the workpiece a.

Since the conventional CNC machining machine is a two-axis machining machine, that is, the X-axis and the Z-axis are axially aligned, so that the turning tool 5 or the center drill 5a can process the workpiece a corresponding to the chuck 1 because the turret 4 is Placed on a carriage 8, referring to FIG. 1 and FIG. 5, the turret 4 is moved obliquely downward along the carriage 8 and is axially adjusted to the workpiece a. The direction of the carriage 8 is The length direction of the processing machine is vertical, and the bottom of the sliding seat 8 is matched with the base 7 of the processing machine, so that the sliding seat 8 can be moved back and forth to the chuck 1 or away from the chuck 1 for Z-axis adjustment, when the workpiece a It is clamped to the chuck 1 and the center drill 5a is mounted on the fixed seat 9, then the slide 8 is moved and the turret 4 is moved, so that the turning tool 5 is moved to the center point of the workpiece a facing the workpiece a. The workpiece a is machined, and it can be seen that the turning tool 5 on the conventional turret 4 can only approach the workpiece a along the base 7 of the processing machine, and then the turning tool 8 of the processing machine causes the turning tool 5 to lean against the workpiece a, only Adjusting the position of the X axis and the Z axis in two directions, causing an error in the Y axis. As a result, the cutting position of the adjustment center drill 5a cannot be completely accurate, which may cause defective products. As shown in FIGS. 6 and 7, when the inner hole is machined to the workpiece a using the turning tool 5b for cutting the inner diameter of the workpiece a, if the turning tool 5b cannot accurately reach the center of the workpiece a, the workpiece a follows the chuck. 1 rotation will generate pressure p on the turning tool 5b, not only the turning tool 5b will be beaten or even broken, and the processed inner hole will lose precision.

Therefore, the main purpose of this creation is to solve the problem that the turning tool and the center drill which are used to process the outer diameter or the inner diameter of the workpiece cannot be adjusted in the Y-axis, so that when the turning tool or the center drill and the center of the chuck are corrected, It is not easy to reach a precise position, causing the tool to jump or even be damaged, and the size of the machined workpiece is not accurate enough.

Another purpose of this creation is to solve the problem that the processing machine uses a fixed seat on the turret to install a drilling tool to machine a countersunk hole, and then change another tool to cut the outer diameter of the workpiece for processing. The length of the ejector pin must extend beyond the width of the holder and the length of the knives protruding from the holder to reach the workpiece. It is often subject to the thimble being fully extended but not reaching the workpiece, but moving the tail The trouble of the seat, and the problem that the turning tool is not easy to be aligned with the workpiece when the small inner diameter is processed.

In order to achieve the above object, the present invention provides a tool holder for a CNC machine, comprising: a carrier and an adjusting component, the carrier is a long rod and is screwed and fixed on a turret rotatable by the processing machine. An assembly portion is disposed at an end away from the turret, and the assembly portion is provided with a set of matching slots and two first screw holes in the same direction as the carrier, the first screw holes communicate with the pair of matching slots and are perpendicular to each other The adjusting component is provided with a cutter hole for assembling a cutter, and the adjusting component is provided with the matching groove a protruding strip and a second elongated hole are provided for the first screw to be threaded, and the first screw is screwed with the first screw hole of the combined portion.

The adjusting portion is provided with a limiting slot that communicates with the group of matching slots and intersects with the group of matching slots, and the adjusting component is provided with an adjusting protrusion matched with the limiting slot, the limiting slot The width is greater than the width of the adjustment protrusion.

Wherein, the width of the limiting groove is greater than the width of the adjusting protrusion is 4 mm.

The upper and lower sides of the combination portion facing the direction of the limiting slot are respectively provided with an upper screw hole and a lower screw hole, wherein the upper screw hole is screwed by an upper screw, and the lower screw hole is screwed by a screw. The end of the lower screw presses the adjustment protrusion.

Wherein, the carrier is a square long rod, the tool hole of the adjusting component is a circular hole and is perpendicular to the grouping groove direction, and the top of the adjusting component is provided with two pressing screw holes, and the pressing screw hole is provided with a pressing screw Screwed, the end of the pressing screw is tight against the tool.

Thereby, when a lever gauge device is mounted on the chuck of the processing machine, a probe protruding from the lever gauge contacts the cutter hole of the adjusting component, and is rotated by hand. When the chuck corrects the center of the tool hole to the center of the chuck, the assembly groove of the carrier and the adjustment convex portion of the adjustment element have a pitch of +-2 mm, and the Y-axis direction is adjusted, and the difference is made. In the traditional processing machine, only the Z axis and the X axis are adjusted in the axial direction. This creation can finely adjust the tool hole in the Y axis direction, so that the X, Y and Z axes can be adjusted to make the center of the tool hole. To the center of the chuck, the workpiece is bored or bored by the tool to achieve precise size and position.

In addition, this creation installs the tool with the adjustment component, and it is more customary to install the machining tool with the fixed seat of the turret. Because the width of the original adjustment component is smaller than the width of the fixed seat, when the tail pin of the processing machine needs to be extended to stand against the workpiece At the end of the counterbore, the creation facilitates the thimble to the workpiece and eliminates the trouble of moving the tailstock. Therefore, the use of the present invention can solve the trouble of moving the tailstock, thereby improving work efficiency.

Even if the workpiece is subjected to cutting inner diameter and drilling without using the ejector pin of the tailstock, the tool life and machining accuracy can be greatly improved because the turning tool can accurately reach the center of the workpiece.
