Description

Technical Field

[0001] The utility model relates to the technical field of laser tube cutting chucks, in particular to a chuck slideway protective cover. Background Art

[0002] The chuck is a widely used tool for clamping the workpiece. For example, the laser cutting production line needs to use a chuck to clamp the workpiece before laser cutting. Common chucks of this type usually consist of a front cover, a rear cover, a pair of horizontal jaws and a pair of longitudinal jaws movably arranged on the front cover, a cylinder for driving the two pairs of jaws to move, a transmission mechanism arranged between the cylinder and the two pairs of jaws, a synchronization mechanism for realizing the synchronous movement of the two pairs of jaws, a frame as an installation basis, and a rotation drive mechanism arranged on the frame for driving the overall rotation of other mechanisms except the frame. The front cover is provided with two slide grooves in the longitudinal and transverse directions, and a slider is arranged in the slide groove. The jaws are fixedly mounted on the slider. The slider moves in the slide groove driven by the transmission mechanism arranged inside the chuck to drive the jaws to move. In order to prevent dust, foreign matter and chips from the cutting process from entering the inside of the chuck, a protective cover is required on the outside of each slide groove of the chuck, such as Figure 1 As shown, the slide groove protection cover of the existing chuck generally adopts an accordion-type protection cover 100 made of fireproof cloth. The disadvantage is that the accordion-type protection cover 100 made of cloth is easily damaged due to hanging, touching, open flame, oil aging and the like during use, and it is necessary to stop the machine in time to replace the slide groove protection cover, which seriously affects the work efficiency of the production line. If the slide groove protection cover is not replaced in time after being damaged, it is easy for processing chips to enter the inside of the chuck, causing damage to the internal transmission mechanism and / or synchronization mechanism of the chuck, so that the chuck cannot work normally and needs to be stopped for maintenance or replacement.

[0030] The materials of the first covering member 3 , the second covering member 4 , the third covering member 5 and the fourth covering member 6 are all steel plates.

[0031] In this embodiment, a set of chuck slot protection covers is provided at each slot 102 of the chuck. Figure 2 The chuck shown in the figure has four slide grooves, and the chuck slide groove protection covers of this embodiment are correspondingly provided with four sets on the chuck.

[0032] The working process and principle of the chuck slideway protective cover of this embodiment are briefly described as follows:

[0033] During the working process, when the slider 103 of the chuck is driven by the driving mechanism of the chuck to move from the outside to the inside from the set starting position in the slide groove 102, driving the clamping jaws 104 to move toward the center hole 101-1 to clamp the workpiece, the movement of the slider 103 synchronously drives the fourth cover member 6 fixed on the slider 103 to move inward. When a certain distance is reached, the sixth hanging plate 62 of the fourth cover member 6 is hung with the third cover member 5 and the fifth hanging plate 53, driving the third cover member 5 to move toward the inside of the chuck. When a certain distance is reached, the fourth hanging plate 52 of the third cover member 5 is hung with the third hanging plate 43 of the second cover member 4, driving the second cover member 4 to move toward the inside of the chuck. When the centripetal movement of the slider 103 reaches the set maximum distance, the second hanging plate 42 of the second cover member 4 is close to the first hanging plate 34 of the first cover member 3 but leaving a gap to prevent pulling. When the slider 103 drives the clamping jaws 104 to move away from the center hole 101-1 to release the workpiece, that is, the slider 103 performs a reset movement, the slider 103 drives the fourth covering member 6 to move outward for a certain distance, and then the limit driving member 2 fixed on the slider 103 contacts the fifth hanging plate 53 of the third covering member 5 to push the third covering member 5 to move outward, and after continuing to move for a distance, the limit driving member 2 contacts the third hanging plate 43 of the second covering member 4 to push the second covering member 4 to move into the first covering member 3, and the slider 103 stops moving when it moves to the set starting position.

[0034] As can be seen from the above, in both motion states, the front cover 101, the slider 103, the two guide plates 1, the first cover 3, the second cover 4, the third cover 5 and the fourth cover 6 always surround each slide groove 102 to form a closed cavity, thereby effectively preventing external dust, chips, etc. from entering the interior of the chuck, and playing the role of a protective cover. At the same time, since the various cover parts of the chuck slide groove protective cover of this embodiment are made of steel plates, it can effectively solve the corresponding technical problems caused by the accordion-type protective cover 100 made of fireproof cloth generally used in the existing similar chuck slide groove protective covers.

[0035] The above embodiments are descriptions of specific implementation methods of the present invention, rather than limitations of the present invention. Technical personnel in the relevant technical field can make various changes and modifications to obtain corresponding equivalent technical solutions without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should be included in the patent protection scope of the present invention.
