Description

Technical Field

[0001] This utility model relates to the field of clamping equipment technology, and in particular to an independent modular pneumatic chuck jaw opening and closing module. Background Technology

[0002] A chuck is a type of clamping equipment that clamps the workpiece to be processed by controlling the movement of the jaw mechanism. A drive mechanism is set inside the chuck, which drives the jaw mechanism to open and close. In the existing technology, the drive mechanism is generally set along the center, and the jaw assembly, opening and closing module and rotation module are connected in series. However, the overall size of the pneumatic chuck is very large, which makes installation and maintenance very inconvenient, and this problem is even more obvious during transportation.

[0003] Moreover, the existing chucks are relatively large in size. Traditional opening and closing mechanisms occupy a large radial volume in order to ensure sufficient chuck travel, causing many inconveniences. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide an independent modular pneumatic chuck jaw opening and closing module, which can effectively reduce the radial space occupied, shrink the chuck volume, and facilitate transportation.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: an independent modular pneumatic chuck jaw opening and closing module, comprising jaw assemblies and an opening and closing mechanism arranged along the outer periphery of the chuck main shaft. The opening and closing mechanism includes an opening and closing slider and a lifting seat. The lifting seat is mounted on the chuck main shaft and can move up and down along the chuck main shaft. The lifting seat is provided with a slider groove, which is inclined. The opening and closing slider includes a mounting part and a wedge-shaped sliding part. Multiple jaw assemblies are mounted on the end face of the chuck. Each jaw assembly includes a jaw and a jaw seat. The jaw seat is inserted into the mounting part of the opening and closing slider. The sliding part of the opening and closing slider is installed in the slider groove and can move along the slider groove when the lifting seat moves up and down, thereby driving the jaw assembly on it to move.

[0006] In the above technical solution, the opening and closing slider is provided with multiple adjustment holes, and the claw seat is fixed on the adjustment holes.

[0007] In the above technical solution, the upper part of the chuck spindle is provided with a flange sealing edge, the end face of the chuck is provided with a jaw seat groove, the jaw seat is installed in the jaw seat groove, a sealing plate is provided between the jaw seat and the flange sealing edge, one end of the sealing plate is embedded in the jaw seat groove and fixed by bolts, and the other end is fastened to the flange sealing edge.

[0008] In the above technical solution, the lifting seat is ring-shaped and mounted on the chuck spindle, and can move axially under the push of the cylinder shaft in the cylinder unit.

[0009] In the above technical solution, the chuck spindle is provided with two lifting seats, and each lifting seat is symmetrically provided with two slider slots.

[0010] In the above technical solution, the inner lifting seat is mounted on the chuck spindle, and the outer lifting seat is mounted on the outer wall of the inner lifting seat. The outer peripheral surface of the outer lifting seat is provided with two connecting holes, which are symmetrically arranged. The inner lifting seat is provided with two connecting ears, which are symmetrically arranged.

[0011] In the above technical solution, the groove opening of the slider groove is provided with a limiting stop, and the sliding part of the opening and closing slider is provided with a limiting step corresponding to the limiting stop.

[0012] In the above technical solution, the bottom of the claw seat is provided with a cross-shaped mounting protrusion, and the mounting part of the opening and closing slider is provided with an adjustment slot, and the mounting protrusion can be engaged into one of the adjustment slots.

[0013] In summary, the advantages of this utility model over traditional technologies are as follows: This utility model optimizes the structure of the pneumatic chuck opening and closing mechanism. The slider groove and the opening and closing slider are set at an angle, which greatly reduces the radial size of the chuck, reduces the volume of the chuck, facilitates transportation, installation and maintenance, and the clamping force is changed from the previous horizontal output to the current inclined output, making the clamping of the jaws more stable.

[0017] The present invention will be further described with reference to the following figures: like Figures 1-7 As shown, an independent modular pneumatic chuck jaw opening and closing module includes a jaw assembly 200 and an opening and closing mechanism 300 arranged along the outer periphery of the chuck main shaft 100. The opening and closing mechanism 300 includes an opening and closing slider 310 and a lifting seat 320. The lifting seat 320 is mounted on the chuck main shaft 100 and can move up and down along the chuck main shaft 100. The lifting seat 320 is provided with a slider groove 330, which is inclined. The opening and closing slider 310 includes... The chuck end face 400 is equipped with a mounting part 311 and a wedge-shaped sliding part 312. Multiple jaw assemblies 200 are mounted on the chuck end face 400. Each jaw assembly 200 includes a jaw 210 and a jaw seat 220. The jaw seat 220 is inserted into the mounting part 311 of the opening and closing slider 310. The sliding part 312 of the opening and closing slider 310 is installed in the slider groove 330 and can move along the slider groove 330 when the lifting seat 320 is raised and lowered, thereby driving the jaw assembly 200 on it to move.

[0018] like Figure 7 As shown, the opening and closing slider 310 is provided with multiple adjustment holes 313, and the claw seat 220 is fixed on the adjustment holes 313.
