SUMMERY OF THE UTILITY MODEL

The utility model provides a be not enough to prior art, the utility model provides a work piece clamping device for industrial robot drilling has solved adjustment work piece processing angle, highly inconvenient, and is relatively poor to the size adaptability of work piece, and fixed not jail and produce the problem of displacement in the use, and can fix simple curved surface (like "U" type curved surface).

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a work piece clamping device for industrial robot drilling, includes the workstation, be fixed with four guide rails on the workstation, all be provided with the slider on the guide rail, all be fixed with on the slider from locking-type hydraulic stem, be connected with the clamping part on the hydraulic stem from locking-type, the clamping part includes stationary dog, no pole cylinder and the follow-up splint that link to each other rather than.

Preferably, the tail end of the sliding block is connected with a pneumatic clamping device.

Preferably, a first positioning block and a second positioning block are arranged on two sides of the clamping part.

Preferably, a swinging cylinder is mounted at the tail end of the self-locking hydraulic rod and connected with the clamping part.

Preferably, an angle sensor is installed on the side surface of the clamping part and connected with the swing cylinder.

Preferably, a scale is engraved on the self-locking hydraulic rod.

Preferably, four limit stop blocks are fixed at four corners of the workbench.

The utility model provides a pair of a work piece clamping device for industrial robot drilling has following beneficial effect: the four clamping jaws fixed on the guide rail can realize translation and pitching to match the size of a workpiece and adjust the machining angle of the workpiece, and the clamping part is provided with the angle sensor, so that the angle of the clamping part can be detected, the self-locking hydraulic rod is engraved with a scale, and the lifting height can be visualized. One end of the sliding block is connected with a pneumatic clamping device, so that the locking of the sliding block moving along the direction of the guide rail can be realized. Through setting up no pole cylinder at the clamping part, drive follow-up splint and stationary dog formation clamping face, because of pressing from both sides tightly through four clamping jaw multi-angles, can possess better fixed effect, prevent to produce the displacement because of the processing atress, improve machining precision and clamping device's suitability, through the removal of slider on the guide rail, the position of adjustable four clamping jaws matches the work piece of equidimension not, has increased clamping device's suitability, and can fix simple curved surface.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.

In the description of the present invention, it is to be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.

Referring to fig. 1 to 4, a workpiece clamping device for industrial robot drilling comprises a workbench 3, four guide rails 2 are fixed on the workbench 3, sliding blocks 4 are arranged on the guide rails 2, self-locking hydraulic rods 7 are fixed on the sliding blocks 4, clamping portions 6 are connected on the self-locking hydraulic rods 7, and each clamping portion 6 comprises a fixed claw 64, a rodless cylinder 61 and a follow-up clamp plate 66 connected with the fixed claw 64 and the rodless cylinder 61. The tail end of the slide block 4 is connected with a pneumatic clamping device 1. The first positioning block 63 and the second positioning block 65 are disposed on both sides of the clamping portion 6. The tail end of the self-locking hydraulic rod 7 is provided with a swinging cylinder 8, and the swinging cylinder 8 is connected with the clamping part 6. An angle sensor 62 is arranged on the side surface of the clamping part 6, and the angle sensor 62 is connected with the swing cylinder 8. Four limit stops 5 are fixed at four corners of the workbench 3.

In the embodiment, the positions of the four sliders 4 are adjusted according to the size of the workpiece, so that the edges of the workpiece are tightly attached to the first positioning block 63 and the second positioning block 65, the pneumatic clamp 1 is used for locking the sliders 4, and the rodless cylinder 61 is connected with the follow-up clamp plate 66 to form a clamping surface with the fixed claw 64, so as to clamp and fix the workpiece. And the proper processing height and angle are obtained by adjusting the expansion of the self-locking hydraulic rod 7 and the rotation of the swinging cylinder 8, the structure is simple, the operation is easy, and because the rodless cylinder 61, the self-locking hydraulic rod 7 and the swinging cylinder 8 are used, some manual operations are reduced, and the service efficiency of the whole clamping device is higher.
