Description

Technical Field

[0001] The utility model relates to the technical field of machine tool equipment manufacturing, in particular to a workbench extension device for a four-axis machining center. Background Art

[0002] When clamping parts, the four-axis machining center equipment is affected by the four-axis indexing head and tailstock top. The actual length of the parts that can be clamped is much shorter than the length of the machine table and the effective travel of the X-axis, thus limiting the range of parts that can be processed. For example, a certain type of machine tool has a table length of 2200mm, an X-axis travel of 1800mm, and is equipped with a four-axis indexing head and a tailstock top. When clamping parts with one clamp and one top, affected by the four-axis indexing head and tailstock top, the actual maximum length of the parts that can be clamped is only 1390mm; assuming that when processing a part with a length of 1800mm, the equipment's table and X-axis travel are both met, but it exceeds the range that can be clamped, so only a larger specification of machine tool equipment can be selected, which will reduce the utilization rate of the machine tool and increase the equipment investment and the manufacturing cost of parts.

[0003] Therefore, how to improve the processing range of a four-axis machining center is a technical problem that technical personnel in this field currently need to solve. Utility Model Content

[0031] Specifically, a tailstock center 003 and a four-axis dividing head 004 are installed on the working platform 002 of the four-axis machining center 001. In order to extend the travel range of the tailstock center 003 and the four-axis dividing head 004 on the working platform 002, an extension plate 100 is fixed to both ends of the working platform 002, wherein the length of the extension plate 100 can be set according to the actual extension length required. After the extension plate 100 is installed, the tailstock center 003 and the four-axis dividing head 004 are respectively installed on the extension plate 100.

At the same time, a positioning key 110 is provided on the lower side of the extension plate 100, and the positioning key 110 is just inserted into the first slide groove 021. It should be noted that the positioning keys 110 of the two extension plates 100 need to be inserted into the same first slide groove 021, so that the extension plates 100 can be positioned so that the two extension plates 100 are on the same straight line, and the processing position of the workpiece clamped by the tailstock top 003 and the four-axis dividing head 004 can be adjusted by adjusting the position of the extension plate 100, that is, the positioning key 110 is matched in the first slide groove 021 at different positions.

[0036] Preferably, a plurality of second slide grooves 120 which are parallel to each other and have equal spacing are disposed on the upper side of the extension plate 100 .

[0037] It can be understood that in order to be able to change the position of the part in the front-to-back direction relative to the four-axis machining center 001, that is, perpendicular to the extension direction of the working platform 002, when the position of the workpiece is not suitable, the tailstock center 003 and the four-axis dividing head 004 can be adjusted to be installed in different second slide grooves 120; it should be noted that although the tailstock center 003 and the four-axis dividing head 004 are respectively installed on different extension plates 100, they are also located on a straight line parallel to the extension direction of the working platform 002.

[0038] Preferably, the first slide groove 021 and the second slide groove 120 have an inverted T-shaped cross section, and the tailstock center 003 and the four-axis dividing head 004 are respectively installed inside the second slide groove 120 located on the same straight line on the two extension plates 100.

[0040] Preferably, the extension plate 100 is provided with a plurality of waist-shaped countersunk holes 130 on both sides of the second slide groove 120 .

[0041] It can be understood that the extension plate 100 needs to be installed on the working platform 002, so a number of holes are symmetrically set on both sides of the extension plate 100. At the same time, in order to prevent the fixing parts from being located on the surface of the extension plate 100 after the extension plate 100 is fixed, affecting the installation of the tailstock top 003 and the four-axis dividing head 004.

[0042] Preferably, the tailstock center 003 and the four-axis dividing head 004, the extension plate 100 and the working platform 002 are fixed by T-shaped nuts and fixing screws 140, and the T-shaped nuts are respectively installed in the first slide groove 021 and the second slide groove 120.

[0043] In this embodiment, in order to be able to more stably and conveniently install the extension plate 100 on the working platform 002 and install the tailstock center 003 and the four-axis dividing head 004 on the extension plate 100, a T-shaped nut and a fixing screw 140 are used for connection; wherein, the overall structure of the T-shaped nut is the same as the first slide groove 021 and the second slide groove 120, and the head of the T-shaped nut can be just embedded in the first slide groove 021 and the second slide groove 120, and then matched with the fixing screw 140 for connection; in the installed state, the T-shaped nut is located in the first slide groove 021 and the second slide groove 120, and the fixing screw 140 is located in the waist-shaped countersunk hole 130.

[0044] Preferably, a distance sensor is provided on the tailstock top 003 or the four-axis dividing head 004 , and the distance sensor can detect the distance from the four-axis dividing head 004 or the tailstock top 003 .

[0045] In another embodiment, a distance sensor is provided on the tailstock top 003 or the four-axis dividing head 004, and the distance sensor can measure the distance to the opposite side, that is, the distance between the tailstock top 003 and the four-axis dividing head 004. This setting can intuitively and quickly determine the processing range of the four-axis machining center 001.

[0046] Preferably, the outer ends of the two extension plates 100 are provided with telescopic cylinders, the tailstock top 003 and the four-axis dividing head 004 are connected to the movable ends of the telescopic cylinders, the telescopic direction of the telescopic cylinders is parallel to the extension direction of the working platform 002, and a control box is also provided on the working platform 002. The distance sensor and the telescopic cylinder are both connected to the control box. The control box can adjust the extension distance of the telescopic cylinder according to the detection results of the distance sensor, thereby changing the distance between the tailstock top 003 and the four-axis dividing head 004.

[0047] Furthermore, telescopic cylinders are connected to the outer sides of the tailstock top 003 and the four-axis dividing head 004, and the telescopic cylinders are respectively installed on the extension plates 100 on both sides. The telescopic ends of the telescopic cylinders are respectively connected to the tailstock top 003 and the four-axis dividing head 004, and the telescopic cylinders are controlled by a control box. The control box is also connected to a distance sensor. In this way, when it is necessary to clamp the processed parts, the distance between the tailstock top 003 and the four-axis dividing head 004 is first read out by the distance sensor. The operator compares the distance with the actual length of the clamped parts, and controls the tailstock top 003 and the four-axis dividing head 004 to move to the appropriate position through the control box, thereby realizing automatic adjustment of the clamping range of the parts.

[0048] Preferably, limit sensors are provided at the outer ends of the two extension plates 100 , and the limit sensors are connected to the control box to prevent the tailstock top 003 or the four-axis dividing head 004 from exceeding the travel range of the extension plates 100 .
