The piston is driven to move by utilizing the air charging and discharging at the two ends of the piston, so that the external slide block moves along with the piston. Because the piston rod is not telescopic, the requirement of installation space is greatly reduced.

As a further improvement, a guide shaft coaxial with the track body is arranged in the track body, and the piston is movably sleeved on the guide shaft. And the deflection is avoided for the piston guiding.

As another further improvement, the device also comprises a mounting plate fixed on the sliding block, wherein the mounting plate is vertically arranged; the grabbing mechanism is fixed on the front surface of the mounting plate; the back of the mounting plate is vertically provided with a grabbing oil cylinder or an air cylinder for driving the clamping jaw to open and close.

As an improvement, the clamping jaws are arranged side by side and share the same grabbing oil cylinder or air cylinder for driving to open and close. Can grab a plurality of work pieces simultaneously, improve conveying efficiency.

As an improvement, the gripper clamp comprises a left clamping block and a right clamping block, and the two clamping blocks are respectively fixed on a left clamping arm and a right clamping arm of the clamping jaw; the inner sides of the left clamping block and the right clamping block are both provided with arc-shaped grooves for clamping workpieces. The gripper clamp is used for matching different workpieces, so that the applicability of the equipment is improved.

As an improvement, the track is horizontally arranged on the rack, and the guide rod is parallel to the track; the sliding block is movably sleeved on the track and the guide rod; the grabbing mechanism is hung on the sliding block and is positioned below the track.

As an improvement, telescopic supporting legs are arranged below the machine frame. The height of the frame can be adjusted to adapt to different working conditions.

The invention has the advantages that: the material grabbing and conveying device with the structure has the advantages that the existing conveying belt is replaced by the grabbing and conveying mode, the equipment is small in size when the conveying is carried in a short distance, the requirement on installation space is low, the safety is high, and the material grabbing and conveying device is suitable for short-distance conveying of small workpieces.

Detailed Description

In order that those skilled in the art will better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the following embodiments.

As shown in fig. 1-4, the present invention comprises a frame 1, and a retractable leg 7 is provided below the frame 1. The transfer mechanism comprises a track 2 fixed on the rack 1 and a slide block 3 capable of sliding back and forth along the track 2; the slide block 3 is provided with a grabbing mechanism 5; the track 2 is horizontally arranged on the rack 1, and the guide rod 4 parallel to the track 2 is also included; the slide block 3 is movably sleeved on the track 2 and the guide rod 4; the grabbing mechanism 5 is hung on the sliding block 3 and is positioned below the track 2. The claw taking mechanism 5 comprises a plurality of clamping jaws 51 and a claw clamp 5 which is matched with the clamping jaws 51 and used for grabbing a workpiece; and the lifting oil cylinder or the air cylinder 6 is used for driving the grabbing mechanism 5 to lift. Specifically, the device further comprises a mounting plate 8 fixed on the sliding block 3, wherein the mounting plate 8 is vertically arranged; the grabbing mechanism 5 is fixed on the front surface of the mounting plate 8; and a grabbing oil cylinder or air cylinder 53 for driving the clamping jaw 51 to open and close is vertically arranged on the back surface of the mounting plate 8.

The track 1 comprises a hollow track body 21, and a piston 22 capable of sliding along the axial direction of the track 1 is arranged in the hollow track body; the piston 22 and the slide block 3 are mutually attracted by magnetism; the two ends of the track body 21 are connected with air pipes 24, and the piston 22 is driven to move through air charging and discharging. A guide shaft 23 coaxial with the track body 21 is arranged in the track body 21, and the piston 22 is movably sleeved on the guide shaft 23.

The clamping jaws are arranged side by side and share the same grabbing oil cylinder or air cylinder to drive the opening and closing. The gripper clamp comprises a left clamping block and a right clamping block, and the two clamping blocks are respectively fixed on a left clamping arm and a right clamping arm of the clamping jaw; the inner sides of the left clamping block and the right clamping block are both provided with arc-shaped grooves for clamping workpieces.
