Description

Technical Field

[0001] The present invention relates to the field of clamping equipment, in particular to an electric intelligent chuck. Background Art

[0002] Laser cutting is one of the most important applications in the laser processing industry. Due to its high speed, high precision, and zero workpiece deformation, it has been widely used in the automotive and rolling stock manufacturing, aviation, chemical, light industry, electrical and electronics, petroleum, and metallurgy industries. In recent years, laser cutting technology has developed rapidly, with an annual growth rate of 20% to 30% internationally. The vast application market for laser cutting, coupled with the rapid development of modern science and technology, has led scientific and technological workers at home and abroad to continuously explore and research laser cutting technology, driving the continuous development of laser cutting technology.

[0003] In the prior art, the chuck is generally driven by the extension and retraction of the cylinder output shaft to drive the claws to open and close, but this structure has great limitations. The cylinder is generally arranged in the bearing seat of the chuck and works with transmission components such as connecting rods, which occupies a large volume. Moreover, the cylinder is pushed by gas when working, which requires an external air circuit. However, the chuck needs to rotate continuously during operation, and the external air circuit pipe will have the problem of entanglement and extrusion when the chuck rotates. A corresponding airtight structure needs to be set during the arrangement to adapt to it. In addition, the pneumatic drive has poor precision and slow response when in use. Summary of the Invention

[0004] In view of the above problems, the present invention aims to provide an electric smart chuck with small size, simple structure and high precision.

[0005] In order to solve the above technical problems, the technical solution adopted by the present invention is as follows: an electric intelligent chuck, comprising a chuck body, a bearing seat, a driving mechanism and a rotating mechanism, the chuck body being mounted on the bearing seat, the driving mechanism being mounted in the bearing seat, and being able to drive the claw assembly on the chuck body to open and close, the rotating mechanism being able to drive the chuck body to rotate, the driving mechanism comprising a driving motor, a transmission assembly, a geared disc assembly and a bridge gear set, the driving motor driving the geared disc assembly to rotate through the transmission assembly, and driving the claw assembly on the chuck body to open and close through the bridge gear set.

[0006] In the above technical solution, the clamping claw assembly includes a sliding block, a fixed claw and a clamping piece. The fixed claw is fixedly arranged on one side of the sliding block close to the geometric center of the chuck body, and the clamping piece is installed at the end of the fixed claw.

[0007] In the above technical solution, a rack is provided on the side of the sliding block, and the bridge gear set is transmission-connected to the rack on the side of the sliding block.

[0008] In the above technical solution, the rotating mechanism includes a rotating motor and a rotating gear, the rotating motor drives the rotating gear to rotate, and the chuck body is fixedly connected to the rotating gear.

[0009] In the above technical solution, the driving mechanism includes two driving motors, and the gear disc assembly includes a first gear disc, a second gear disc and a third gear disc. The two driving motors drive the first gear disc and the second gear disc respectively, and the third gear disc is fixedly connected to the second gear disc.

[0010] In the above technical solution, the first gear plate and the second gear plate are both drivingly connected to two bridge gear sets, and each of the bridge gear sets is drivingly connected to the claw assembly.

[0011] In the above technical solution, the driving mechanism includes a driving motor, which drives the sprocket of the sprocket assembly and drives several bridge gear sets that are transmission-connected to the sprocket, and each bridge gear set is transmission-connected to the claw assembly.

[0012] In the above technical solution, two proximity switches are provided on the bearing seat.

[0013] In summary, the technical solution of the present invention has the following beneficial effects compared with traditional technical means:

[0014] The driving mechanism in the present invention adopts the form of a motor combined with gears. Compared with traditional pneumatic chucks, the overall rotational inertia is smaller and can achieve high rotation speed. At the same time, the motor drive accuracy is higher, and the clamping force of the clamping jaws can be quickly and effectively adjusted by the motor, which can effectively clamp thin-walled tubes. It has wider applicability and does not require a special airtight structure, effectively reducing costs.

[0015] Compared with other traditional electric chucks, since the motor peripherals are located outside the bearing seat, no collector rings are required to arrange the circuits, which has a long service life and the chuck is more durable. At the same time, the motor is located outside the chuck, which is easy to maintain and repair. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0027] The following is a guide based on the ideal embodiments of the present invention. Through the following description, relevant personnel can make various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.

[0028] The present invention will be further described with reference to the following drawings:

[0029] like Figures 1 to 9As shown, an electric intelligent chuck includes a chuck body 100, a bearing seat 200, a driving mechanism 300 and a rotating mechanism 400. The chuck body 100 is mounted on the bearing seat 200, and the driving mechanism 300 is mounted in the bearing seat 200, and can drive the claw assembly 110 on the chuck body 100 to open and close. The rotating mechanism 400 can drive the chuck body 100 to rotate. The driving mechanism 300 includes a driving motor 310, a transmission assembly 320, a geared disc assembly 330 and a bridge gear set 340. The driving motor 310 drives the geared disc assembly 330 to rotate through the transmission assembly 320, and drives the claw assembly 110 on the chuck body 100 to open and close through the bridge gear set 340.

[0030] like Figure 1 As shown, the chuck body 100 is mounted on a bearing and is rotatably connected to the bearing seat 200 through the bearing.

[0031] like Figure 9 As shown, the jaw assembly 110 includes a sliding block 111, a fixed jaw 112 and a clamping member 113. The fixed jaw 112 is fixedly arranged on one side of the sliding block 111 close to the geometric center of the chuck body 100. The clamping member 113 is installed at the end of the fixed jaw 112. Two fixed jaws 112 are provided on the sliding block 111, and each fixed jaw 112 is provided with a clamping member 113, which can ensure that the clamping is more stable.

[0032] like Figure 9 As shown, a rack is provided on the side of the sliding block 111, and the bridge gear set 340 is connected to the rack on the side of the sliding block 111. The sliding block 111 is driven to move along the preset track through the cooperation of the gear and the rack, with higher precision.

[0033] like Figure 2 As shown, the rotating mechanism 400 includes a rotating motor 410 and a rotating gear 420. The rotating motor 410 drives the rotating gear 420 to rotate. The chuck body 100 is fixedly connected to the rotating gear 420. The rotating mechanism 400 controls the overall rotation of the chuck.

[0034] like Figure 5 、 6 As shown in Figures 7 and 8, the drive mechanism 300 includes two drive motors 310, and the gear plate assembly 330 includes a first gear plate 331, a second gear plate 332 and a third gear plate 333. The two drive motors 310 drive the first gear plate 331 and the second gear plate 332 respectively. The third gear plate 333 is fixedly connected to the first gear plate 331. In order to avoid the transmission assembly 320 being too long and to ensure the strength, a linkage relationship between the first gear plate 331 and the third gear plate 333 is set. While driving the first gear plate 331, the third gear plate 333 drives the bridge gear set 340.

[0035] The first gear plate 331 and the second gear plate 332 are both transmission-connected to two bridge gear sets 340, and each bridge gear set 340 is transmission-connected to a claw assembly 110. Any number of bridge gear sets 340 can be transmission-connected to each gear plate, and the claw assemblies 110 on different bridge gear sets 340 on the same gear plate will open and close synchronously.

[0036] Of course, the driving mechanism 300 may also include a driving motor 310, which drives the gear of the gear assembly 330 and drives several bridge gear sets 340 that are connected to the gear, and each bridge gear set 340 is connected to the claw assembly 110. In this way, the claw assemblies 110 that are connected to the bridge gear set 340 are opened and closed synchronously. If properly debugged, three, four or even more bridge gear sets 340 can also achieve material clamping.

[0037] Of course, the gear assembly 330 can also include several gears, each of which is connected to the corresponding bridge gear set 340. For example, if four gears are set and each gear is connected to a bridge gear set 340, the four claw assemblies can operate independently.

[0038] like Figure 1 、 2 As shown, two proximity switches 210 are provided on the bearing seat 200 for monitoring the real-time position of the chuck.

[0039] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
