Description

Technical Field

[0001] The utility model belongs to the technical field of cutting machines, and in particular relates to an automatic cutting machine for sliding bearings. Background Art

[0002] The cutting machine comprises an operating table, a clamping mechanism, a cutting mechanism and a lifting mechanism. The cutting mechanism is lifted and installed in the cutting area by the lifting mechanism, and the clamping mechanism is used to clamp the workpiece in the cutting area.

[0003] A cutting machine is required in the production of sliding bearings. When the cutting machine cuts the sliding bearings, the size of the sliding bearings is determined manually, and then fixed by a clamping mechanism. Manual size measurement is inefficient and has low accuracy, which is not conducive to the continuous production of sliding bearings. In addition, the existing sliding bearings do not hold the cutting sections during cutting, which causes the sliding bearings to vibrate during cutting. The vibrating sliding bearings will hit the cutting blade of the cutting mechanism, causing damage to the cutting blade and reducing the service life of the cutting blade. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] refer to Figure 1-2 As shown, the utility model provides an automatic cutting machine for sliding bearings, comprising: an equipment body with a cutting machine body 6, a feeding area for conveying columnar materials 3 facing the cutting machine body 6 is provided on the equipment body, a first clamping sleeve 4 and a second clamping sleeve 8 are symmetrically installed on both sides of the equipment body and are coaxially movable with the feeding area, a clamping space for clamping the columnar material 3 is formed on the first clamping sleeve 4 and the second clamping sleeve 8, and a cutting area for cutting the columnar material 3 is formed between the equipment body and the first clamping sleeve 4 or the second clamping sleeve 8.

[0025] In the present utility model, combined with Figure 2 and Figure 4 As shown, the equipment body of this embodiment includes a machine tool 1, and a material feeding hole 16 is horizontally penetrated through the machine tool 1. The material feeding area is formed between the first clamping sleeve 4, the material feeding hole 16 and the second clamping sleeve 8.

[0026] Combination Figure 3 As shown, the first cylinder 5 and the first clamping block 9 are installed in sequence from top to bottom at the top of the first clamping sleeve 4 and the second clamping sleeve 8 , and the first clamping block 9 is in contact with the columnar material 3 .

[0027] As described above, in the use of the cutting machine body 6, the equipment body, the first clamping sleeve 4 and the second clamping sleeve 8 provided by the utility model, the columnar material 3 is placed on the machine tool 1 through the feed hole 16. In the figure, the cutting machine body 6 is arranged on the side of the top of the machine tool 1 close to the second clamping sleeve 8. When the equipment is in use, the columnar material 3 is inserted into the first clamping sleeve 4 and the feed hole 16. At this time, the first clamping sleeve 4 clamps the columnar material 3. When the first clamping sleeve 4 moves to one side of the machine tool 1, one end of the columnar material 3 is abutted against the clamping part on the second clamping sleeve 8. At this time, the columnar material 3 is in the initial position on the equipment body, and the first clamping sleeve 4 always keeps clamping the columnar material 3. At this time, the first clamping sleeve 4 The clamping part on the second clamping sleeve 8 rises, allowing the first clamping sleeve 4 to move to one side of the machine tool 1 again. At this time, the distance moved by the machine tool 1 is the length that the columnar material 3 needs to be cut. When the columnar material 3 stops moving, the columnar material 3 is clamped by the clamping part in the second clamping sleeve 8. At this time, the cutting machine body 6 is lifted and lowered to cut the columnar material 3. Since the second clamping sleeve 8 clamps the end of the columnar material 3, the columnar material 3 is prevented from vibrating and contacting the cutting blade on the cutting machine body 6 during cutting. When the first clamping sleeve 4 and the second clamping sleeve 8 clamp the columnar material 3, the first clamping block 9 is driven by the first cylinder to abut against the columnar material 3, thereby completing the clamping of the columnar material 3.

[0028] In the present utility model, combined with Figure 2 As shown, the machine tool 1 of this embodiment is also equipped with two moving mechanisms for driving the first clamping sleeve 4 and the second clamping sleeve 8 to move.

[0029] Combination Figure 2 As shown, the moving mechanism includes a moving rod 2 and a screw 14 screwed to the moving rod 2. A mounting bin 17 parallel to the feed hole 16 is provided on the machine tool 1. Each screw 14 is rotatably mounted in the corresponding mounting bin 17. One ends of the two moving rods 2 are bent and extended to the bottom ends of the first clamping sleeve 4 and the second clamping sleeve 8 respectively. A driving member for rotational driving is installed at one end of each screw 14.

[0030] As described above, when using the moving mechanism provided by the utility model, the screw 14 in the moving mechanism is rotatably installed on the machine tool 1 through the mounting bin 17, and each moving rod 2 is installed on the screw 14. When the driving member is started, the moving rod 2 is driven to move in the mounting bin 17, thereby driving the first clamping sleeve 4 or the second clamping sleeve 8 to approach the machine tool 1 or move away from the machine tool 1.

[0031] Further, in order to accurately determine the size of the columnar material 3 to be cut, refer to Figure 2As shown, the driving member is a servo motor 12. The servo motor 12 can drive the screw 14 to rotate, so as to drive the moving rod 2 to move. At the same time, the moving distance of the moving rod 2 can be detected by the number of revolutions of the servo motor 12, so as to adjust the feeding length of the columnar material 3, and then accurately position the cutting size of the columnar material 3, so as to realize the automatic feeding function of the equipment.

[0032] Further, in order to improve the stability of the movement of the moving rod 2, refer to Figure 3-5 As shown, each installation bin 17 is provided with a limit slot 15 in the axial direction, and each moving rod 2 is provided with a limit block 13 that can move in the corresponding limit slot 15. The moving rod 2 is guided to move linearly in the installation bin 17 through the limit block 13 and the limit slot 15 to prevent the moving rod 2 from deflecting when moving.

[0033] Further, in order to clamp the columnar material 3 in the feeding hole 16, refer to Figure 2 As shown, a groove 10 is also provided at the top of the feeding hole 16 near the cutting machine body 6, and the second cylinder 7 and the second clamping block 11 are sequentially installed in the groove 10 from top to bottom, and the second clamping block 11 abuts against the columnar material 3. The second cylinder 7 and the second clamping block 11 are longitudinally installed above the columnar material 3 through the groove 10. When the cutting machine body 6 cuts the columnar material 3, the second cylinder 7 is started, driving the second clamping block 11 to abut against the columnar material 3, thereby fixing the cutting area of ​​the columnar material 3.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
