Detailed Description
The present utility model will be described in further detail with reference to the drawings and examples, in order to make the objects, technical solutions and advantages of the present utility model more apparent. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the utility model.
As shown in fig. 1-7, a fixture for a lamp frame support comprises a base plate 1,
the clamping assemblies 2 are arranged in three, and the three clamping assemblies 2 are distributed in a triangle;
the fool-proof assembly 3 is arranged on the bottom plate 1, and the fool-proof assembly 3 is used for guiding the assembly of the workpiece;
the auxiliary support assembly 4, auxiliary support assembly 4 sets up a plurality of, and auxiliary support assembly 4 sets up the processing station department at the work piece.
In the structure, the three clamping assemblies 2 are main clamping pieces, and the three points of the workpiece are clamped to determine the clamping plane, so that the workpiece is stably clamped; the workpiece placement direction is determined through the fool-proof assembly 3, so that the workpiece is prevented from being inclined, the workpiece is guided, and the workpiece is convenient to be installed. The auxiliary supporting component 4 is used for supporting the workpiece so as to prevent deformation of a processing part during processing.
In one embodiment, as shown in fig. 1-7, to ensure that the workpiece is mounted in place, a positioning assembly 5 is also provided, the workpiece mounting position being defined by the positioning assembly 5. Specifically, the positioning assembly 5 includes a positioning seat 51 and a diamond pin 52 disposed on the positioning seat 51; blind holes suitable for the hidden positions of the workpieces are utilized; when clamping the workpiece, the blind holes are inserted into the diamond pins 52 to position the workpiece.
In one embodiment, as shown in fig. 1-7, the fool-proof assembly 3 includes at least three fool-proof rods 31, a fixing base 32 is disposed at the lower end of the fool-proof rod 31, and a waist-shaped hole 33 is disposed on the fixing base 32. The fixed orifices are preset to bottom plate 1, prevent slow-witted pole 31 and be connected with the base through the bolt, through bolt and waist type hole cooperation, but the position of horizontal adjustment prevents slow-witted pole 31, and then according to the distance of product shape adjustment slow-witted pole and work piece.
