Description

Technical Field

[0001] The utility model relates to the technical field of numerical control machine tools, in particular to a guide rail machining and positioning device for numerical control machine tools. Background Art

[0002] The moving parts of CNC machine tools all run along the guide rails on its bed, columns, beams and other parts. The guide rails play a supporting and guiding role. The quality of the guide rails has a great influence on the rigidity, processing accuracy and service life of the machine tool. There are many types of guide rails for existing CNC machine tools. For vertical T-type slide plate guide rails, the existing vertical T-type slide plate guide rails are as follows: Figure 1 As shown, when processing a hole in the middle of the vertical T-type slide slider guide rail, it is necessary to position the vertical T-type slide slider guide rail. When the existing positioning device is in use, it can only perform a simple press positioning on the vertical T-type slide slider guide rail. When drilling, due to the large rotation force of the drill bit, it is easy to cause the vertical T-type slide slider guide rail to be offset after positioning. Moreover, multiple drilling operations are required, which requires the staff to frequently adjust the position of the vertical T-type slide slider guide rail, which is cumbersome and has low accuracy.

DETAILED DESCRIPTION

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Example

[0019] Reference Figure 2 and 3 A CNC machine tool guide rail machining positioning device comprises a first fixing plate 1 and a plurality of supporting legs 2, wherein the plurality of supporting legs 2 are all fixed on the first fixing plate 1, and a plurality of positioning mechanisms are symmetrically fixed on the first fixing plate 1, wherein the positioning mechanism comprises a second fixing plate 3, wherein the second fixing plate 3 is fixed on the first fixing plate 1, and a fixing block 4 is fixed on the second fixing plate 3, and an electric telescopic rod 5 is obliquely fixed on the fixing block 4, and a fixing column 6 is fixed on the push rod of the electric telescopic rod 5, and a first broken line with an acute angle is fixed on the fixing column 6 The clamping block 7, the first clamping block 7 with an acute angle and a broken line shape is more matched with the shape of the vertical T-shaped slide slide rail, so that when multiple first clamping blocks 7 clamp the vertical T-shaped slide slide rail, the vertical T-shaped slide slide rail can be clamped and positioned more firmly. Two second clamping blocks 8 are symmetrically fixed on each first clamping block 7. Multiple holes 9 are penetrated and connected on the first fixed plate 1. The multiple holes 9 correspond to the positions where holes need to be punched on the vertical T-shaped slide slide rail, ensuring smooth punching of the vertical T-shaped slide slide rail.

[0020] Working principle: When in use, place the vertical T-shaped slide plate slider guide rail on the first fixed plate 1, start multiple electric telescopic rods 5, extend the multiple electric telescopic rods 5, and evenly and symmetrically engage the multiple first clamping blocks 7 on the vertical T-shaped slide plate slider guide rail. Position the vertical T-shaped slide plate slider guide rail firmly on the first fixed plate 1, and at this time, multiple holes 9 correspond to the positions where holes need to be punched on the vertical T-shaped slide plate slider guide rail. When drilling the vertical T-shaped slide plate slider guide rail, the vertical T-shaped slide plate slider guide rail will not be offset. While reducing the workload of the staff, it can also ensure that the position of the vertical T-shaped slide plate slider guide rail is always accurate. Example

[0021] In the first embodiment, the waste chips falling from the plurality of holes 9 will directly fall onto the floor of the workshop below the first fixing plate 1, which is easy to pollute the floor of the workshop. Figure 2-4 As another preferred embodiment of the utility model, the difference from Embodiment 1 is that a box body 10 is fixed on the first fixed plate 1, and multiple holes 9 are arranged inside the box body 10. The box body 10 is used to collect waste chips that fall from the multiple holes 9 respectively, so as to prevent the waste chips from falling onto the floor of the workshop, thereby facilitating the unified collection of waste chips by the staff.

[0022] A discharge mechanism is fixed on the box body 10, and the discharge mechanism includes two discharge holes 14. The two discharge holes 14 are symmetrical and penetrate the bottom wall of the box body 10. A push plate 11 is slidably inserted in the box body 10 between the two discharge holes 14. The two discharge holes 14 are at a distance from the waste chips collected in the box body 10, so that the waste chips collected in the box body 10 will not be discharged through the two discharge holes 14 when not pushed by the push plate 11. Two push-pull components are symmetrically fixed on the push plate 11. The two push-pull components push the waste chips received in the box body 10 to the two discharge holes 14, and when discharging, the discharge position of the waste chips is reduced, which is convenient for the unified discharge of the waste chips in the box body 10.

[0023] The push-pull assembly includes a limiting groove 15, which is arranged on the side wall of the box body 10. A push rod 12 is inserted through the limiting groove 15 and slidably installed. One end of the push rod 12 is fixed on the push plate 11, and the other end is fixed with a baffle 13. By pulling the two baffles 13 back and forth, the two push rods 12 can drive the push plate 11 to move back and forth in the box body 10, thereby pushing the waste chips in the box body 10 to the two discharge holes 14.

[0024] Working principle: When in use, the waste chips generated when drilling the vertical T-type slide rail slide rail fall into the box body 10 through the multiple holes 9 respectively. When the waste chips collected in the box body 10 need to be processed uniformly, the two baffles 13 are pulled back and forth, and the two push rods 12 can drive the push plate 11 to move back and forth in the box body 10. The reciprocating push plate 11 is used to push the waste chips in the box body 10 to the two discharge holes 14, and discharged through the two discharge holes 14, which is convenient for the staff to collect the waste chips.

[0025] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
