Description
A special fixture for processing thin-wall workpieces.
Technical Field
The invention belongs to the technical field of machining, and particularly relates to a special clamp for machining a thin-wall workpiece.
Background
in the machining process of a thin-wall workpiece, the clamp shown in the attached drawing 1 is generally adopted for positioning, the clamp comprises a clamp bottom plate (1), a horizontal pressing plate (2) and a V-shaped positioning block (3) are fixed on the clamp bottom plate (1), the workpiece (4) is positioned by the V-shaped positioning block (3), the horizontal pressing plate (2) is pressed tightly, and the workpiece is a thin-wall workpiece, so that deformation is generated in the clamping process, the inner roundness of the machined workpiece is out of tolerance, and the roundness of an inner hole is unqualified after boring.
Disclosure of Invention
In order to make up for the defects of the prior art, the invention provides the special fixture for machining the thin-wall workpiece, which can reduce the clamping deformation, improve the machining precision of the product and ensure that the roundness of the inner hole of the workpiece is qualified.
The invention is realized by the following technical scheme:
A special fixture for processing thin-wall workpieces is characterized in that: the clamp comprises a clamp bottom plate, a bracket is fixed on the clamp bottom plate, and a horizontal pressing plate is fixed at the top of the bracket; an inverted V-shaped pressing block is movably connected below the horizontal pressing plate; a movable V-shaped positioning block is arranged right below the inverted V-shaped pressing block; the inverted V-shaped pressing block corresponds to the V-shaped positioning block vertically, and the workpiece fixing clamp is placed between the inverted V-shaped pressing block and the V-shaped positioning block.
As a preferred scheme, the horizontal pressing plate is movably connected with the inverted V-shaped pressing block through a connecting screw I.
Furthermore, a waist-shaped groove is formed in the horizontal pressing plate, a connecting screw I penetrates through the waist-shaped groove and is movably connected with the inverted V-shaped pressing block, and the connecting screw I moves left and right in the waist-shaped groove to move to achieve the position movement of the inverted V-shaped pressing block.
Furthermore, one end of the V-shaped positioning block is fixed on the vertical rod in the vertical direction, the connecting screw II penetrates through the waist-shaped groove and is movably connected with the vertical rod, and the connecting screw II moves left and right in the waist-shaped groove to realize position movement of the V-shaped positioning block.
The invention has the beneficial effects that: the invention has simple structure, can realize accurate positioning of the workpiece, can effectively reduce clamping deformation, improves the processing precision of products, ensures that the roundness of the inner hole of the workpiece is qualified, and improves the product quality.
Drawings
Fig. 1 is a schematic diagram of a prior art structure.
Fig. 2 is a schematic structural diagram of the present invention.
In the figure, 1 clamp bottom plate, 2 horizontal pressing plates, 3V-shaped positioning, 4 workpieces, 5 supports, 6 waist-shaped grooves, 7 connecting screws I, 8V-shaped pressing, 9 vertical rods and 10 connecting screws II are arranged.
Detailed Description
The present invention will be described in further detail with reference to the drawings and detailed description, so as to enable those skilled in the art to more fully, accurately and deeply understand the concept and technical solution of the present invention, and the scope of the present invention includes but is not limited to the following examples, and any modifications made to the details and form of the technical solution of the present invention can be made within the scope of the present invention without departing from the spirit and scope of the present application.
The drawing is an embodiment of the invention. The clamp comprises a clamp bottom plate 1, a bracket 5 is fixed on the clamp bottom plate 1, and a horizontal pressing plate 2 is fixed at the top of the bracket 5; an inverted V-shaped pressing block 8 is movably connected below the horizontal pressing plate 2; a movable V-shaped positioning block 3 is arranged right below the inverted V-shaped pressing block 8; the inverted V-shaped pressing block 8 corresponds to the V-shaped positioning block 3 up and down, and the workpiece 4 is fixedly clamped between the inverted V-shaped pressing block 8 and the V-shaped positioning block 3; the horizontal pressing plate 2 is movably connected with the inverted V-shaped pressing block 8 through a connecting screw I7; a waist-shaped groove 6 is formed in the horizontal pressing plate 2, and a connecting screw I7 penetrates through the waist-shaped groove 6 to be movably connected with an inverted V-shaped pressing block 8; one end of the V-shaped positioning block 3 is fixed on the vertical rod 9 in the vertical direction, and the connecting screw II 10 penetrates through the waist-shaped groove 6 to be movably connected with the vertical rod 9.
The workpiece 4 of this embodiment is a rotary thin-walled workpiece, when using, select suitable position fixed bolster 5 on anchor clamps bottom plate 1, place workpiece 4 needs the clamping position on V type locating piece 3, then tighten connecting screw II 10, drive type V compact heap 8 with connecting screw I7 in waist type groove 6 and move to directly over workpiece 4 and then tighten connecting screw I7 and compress tightly workpiece 4 with type V compact heap 8, easy operation, this method can effectively reduce the clamping and warp, improve product machining precision, ensure that the work piece hole circularity is qualified.
