Description

Technical Field

[0001] The utility model relates to the technical field of chucks used in laser cutting production lines, in particular to an integral chuck with a speed reduction mechanism. Background Art

[0002] The chuck is a necessary auxiliary tool for clamping the workpiece on the laser cutting production line. Common chucks at present include a double gear ring transmission chuck disclosed in the Chinese patent document with the authorization number CN220761400U, and a gear rack transmission full-stroke heavy-duty laser tube cutting chuck disclosed in the Chinese patent document with the application publication number CN114985921A. Such chucks are usually composed of a front cover, a rear cover, a pair of transverse clamping jaws and a pair of longitudinal clamping jaws movably arranged on the front cover, a synchronous driving mechanism driving the two pairs of clamping jaws to move synchronously, a frame as an installation base, and a rotating driving mechanism arranged on the frame for driving the front cover and the rear cover and the related mechanisms arranged thereon to rotate as a whole so that the two pairs of clamping jaws can clamp the workpiece and rotate together during operation. The rotating driving mechanism mainly includes a large gear arranged on the frame and connected to the rear cover, a reducer connected to the large gear, and the reducer is connected to the power motor for rotational drive when in use. At present, the common practice in the industry of this type of chuck is that the manufacturer does not install the reducer on the chuck when shipping. The customer has to configure and install the reducer and connect it to the large gear transmission by himself, or the manufacturer provides the reducer and ships it separately to the customer for self-installation upon customer's needs. Although this method may save customers' costs to a certain extent, it also has its shortcomings: it is not only laborious for customers to install the reducer by themselves, but more importantly, since they are not the manufacturer of the chuck, it is easy to install it eccentrically, which affects the performance and service life of the chuck. Summary of the invention

[0003] The purpose of the utility model is to provide an integral chuck with a speed reduction mechanism in view of the problems existing in the prior art.

[0004] The technical scheme of the utility model is as follows: the integral chuck with a speed reduction mechanism of the utility model comprises a frame, a front cover and a rear cover arranged on the frame, a pair of clamping jaws are arranged in the horizontal direction and in the longitudinal direction on the front side of the front cover, a synchronous driving mechanism arranged between the front cover and the rear cover for driving the two pairs of clamping jaws to move, and a rotation driving mechanism for driving the front cover, the rear cover, the clamping jaws and the synchronous driving mechanism to rotate as a whole, and its structural characteristics are as follows: the above-mentioned rotation driving mechanism comprises a large gear box detachably fixed on the frame, a small gear box detachably fixed on the large gear box, a large gear rotatably arranged in the large gear box and connected to the rear cover for transmission, a transmission shaft rotatably arranged in the small gear box, a first transmission gear arranged in the small gear box and fixedly connected to the transmission shaft, a second transmission gear arranged in the small gear box and meshing with the first transmission gear, a third transmission gear arranged in the large gear box and meshing with the large gear, and a connecting shaft whose two ends are respectively fixedly connected to the second transmission gear and the third transmission gear; the first transmission gear and the second transmission gear constitute a primary speed reduction, and the third transmission gear and the large gear constitute a secondary speed reduction.

[0005] A further solution is that the diameters of the first transmission gear, the third transmission gear, the second transmission gear and the large gear increase in sequence.

[0006] A further solution is that the above-mentioned integrated chuck with speed reduction mechanism also includes a dust cover fixedly arranged on the outer periphery between the above-mentioned front cover and the rear cover.

[0007] The utility model has positive effects: the utility model provides a two-stage reduction structure design in the rotary drive mechanism, and arranges it on the chuck to form an integral chuck. When using, the customer only needs to connect the transmission shaft of the rotary drive mechanism with the power motor used for rotary drive, without having to install the reducer by themselves and then connect it to the power motor, thereby effectively solving the technical problems in the prior art that the reducer must be installed by the customer himself, which is laborious and easy to install eccentrically, affecting the performance and service life of the chuck.

Detailed implementation manners

[0014] The present utility model will be further described in detail below with reference to the drawings and specific implementation manners.

[0015] (Embodiment 1)

[0016] See Figures 1 to 4 , the integral chuck with a speed reduction mechanism in this embodiment mainly consists of a frame 1 as an installation base, a front cover 2 and a rear cover 3 provided on the frame 1, a pair of clamping jaws 4 respectively arranged horizontally and vertically on the front side of the front cover 2, a synchronous drive mechanism (not labeled in the figure) provided between the front cover 2 and the rear cover 3 for driving the two pairs of clamping jaws 4 to move, a dust cover 5 provided on the outer periphery between the front cover 2 and the rear cover 3, and a rotary drive mechanism 6 for driving the overall rotation of the front cover 2, the rear cover 3, the clamping jaws 4, the synchronous drive mechanism, and the dust cover 5, so as to finally make the clamping jaws 4 clamp the workpiece to be processed and rotate; among them, the dust cover 5 is set as a preferred mode. It should be noted that in the foregoing structure of the integral chuck with a speed reduction mechanism in this embodiment, except for the rotary drive mechanism 6, the others are all prior arts and will not be elaborated.

[0017] The rotary drive mechanism 6 in this embodiment mainly consists of a large gearbox 61, a small gearbox 62, a large gear 63, a transmission shaft 64, a first transmission gear 65, a second transmission gear 66, a connecting shaft 67, and a third transmission gear 68.
