Detailed Description
For the convenience of understanding by those skilled in the art, the structure of the present utility model will now be described in further detail with reference to the accompanying drawings:
In the description of the present utility model, the terms "first," "second," and the like are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. The terms "upper," "lower," "side," "end," and the like are used for convenience in describing and simplifying the present utility model based on the orientation or positional relationship shown in the drawings, and do not denote or imply that the device or element in question must have a specific orientation, be constructed and operated in a specific orientation, and thus should not be construed as limiting the present utility model.
Referring to fig. 1-3, a part positioning fixture comprises a cylinder 2, a fixing piece 3, a workbench 4 for placing parts and a push plate 51 assembly 5.
The cylinder 2, the fixing piece 3, the workbench 4 and the push plate 51 assembly 5 are all arranged on a base frame, and the base frame is composed of 2 vertical straight frames 11 and 1 horizontal frame 12 which is horizontally arranged.
The cylinder 2 is a three-section cylinder 2, and the cylinder 2 is mounted on a transverse frame 12 through a mounting piece 8, wherein the mounting piece 8 is a conventional hardware component.
The fixing piece 3 is a vacuum adsorption platform, and a CNC vacuum chuck platform can be adopted. In order to facilitate the up-and-down displacement of the fixing piece 3, 2 slide rails are arranged on the straight frame 11 of the base frame for the installation of the fixing piece 3.
The number of the work tables 4 is 2, and the 2 work tables 4 are arranged side by side with a gap reserved in the middle.
The push plate 51 assembly 5 comprises a push plate 51 and a movable part for displacing the push plate 51; the push plate 51 is located on the surface of the table 4. The movable part comprises a connecting arm 52 fixedly connected with the push plate 51, a screw 53 penetrating through the connecting arm 52, a worm wheel 54 arranged at one end of the screw 53, a worm 55 meshed with the worm wheel 54, and a servo motor 56 for driving the worm 55 to rotate; the connecting arm 52 is placed in the reserved gap between the 2 work tables 4; the screw 53 is in threaded connection with the connecting arm 52; the connecting arm 52 is provided with a screw hole for inserting the screw 53. When the servo motor 56 is started, the worm 55 rotates to drive the worm wheel 54 to rotate, so that the screw 53 rotates, the connecting arm 52 achieves the displacement effect through threads on the screw 53, and the push plate 51 is driven to move on the workbench 4 through the connecting arm 52, so that the push plate 51 can push parts on the workbench 4 to displace. The driving structure of the worm wheel 54 and the worm 55 can avoid the condition that the push plate 51 is retracted after the parts are stressed.
The balls 57 are provided on both sides of the connecting arm 52, and the balls 57 are attached to the 2 tables 4. The connecting arm 52 is limited through the 2 work tables 4, so that the connecting arm 52 is prevented from rotating along with the rotation of the screw 53; and secondly, friction between the connecting arm 52 and the workbench 4 is reduced, so that the connecting arm 52 can be displaced more smoothly.
Preferably, a scale 6 for measuring the height of the workbench 4 is arranged on one side of the workbench 4. So when the part is placed behind workstation 4, scale 6 can be used to measure both total heights, carries out corresponding regulation to cylinder 2 through electric cabinet 7 that locates the bed frame rear side.
Working principle: by placing the part on the workbench 4, then starting the cylinder 2, the piston of the cylinder 2 drives the fixing piece 3 to move downwards to press the part and perform vacuum adsorption fixing, and then the part can be processed. When the position of a part on the workbench 4 needs to be regulated, the fixing piece 3 is disconnected, the piston of the air cylinder 2 is retracted, then the servo motor 56 drives the worm 55, the worm 55 rotates to drive the worm wheel 54 to rotate in a rolling way, so that the screw 53 rotates, the connecting arm 52 realizes displacement through threads on the screw 53, and the connecting arm 52 drives the push plate 51 to move on the workbench 4, so that the push plate 51 can push the part on the workbench 4 to displace.
