Automobile part turning tool

Abstract

The invention discloses an automobile part turning tool. The automobile part turning tool comprises a flange plate bottom plate, left and right slide blocks, a center automatic-aligning inclined supporting block, a slide block bracket, a slide supporting block, a pulling rod, a rotary shaft and a pin, wherein a screw hole is formed in a flange plate to lock with a numerical-control lathe main shaft; a hole for allowing the pulling rod to pass through is formed in the flange plate; the automatic-aligning inclined supporting block and the slide supporting block are fixedly arranged on the flangeplate; the slide block bracket is connected with a pulling rod movable joint; and the two ends of the bracket are connected with the left and right slide blocks through rotary shafts. The product appearance has symmetrical inclined surfaces, so that in the X direction, a product inner cavity has symmetrical inclined surfaces, and in a Y direction, the left and right slide blocks automatically align, position and clamp in the X direction; the center automatic-aligning inclined supporting block is automatically centered, aligned and positioned in the Y direction; and according to the back-off inclined surface in the X direction, a hydraulic pulling rod drives the left and right slide blocks to firmly lock the product on the Y-direction automatic aligning inclined support block through the slide block bracket, so that the automatic clamping purpose is realized.

Description

technical field [0001] The invention relates to an external thread processing device for a frame bracket of an automobile, belonging to the technical field of automobile manufacturing. Background technique [0002] When turning many metal parts, due to the influence of the part structure, the hydraulic rod of the lathe itself cannot be used for automatic tightening, so workers need to use a wrench to manually lock, which not only increases the clamping time, but also increases the labor intensity of the workers. Under the background of modern labor shortage, this kind of tooling cannot meet the production needs and is not popular among workers. [0003] Especially for non-circular parts in the clamping part, ordinary tooling cannot achieve symmetrical center of weight and cannot rotate smoothly. The centrifugal force is relatively large during turning, and the workpiece is affected by the centrifugal force, which reduces the concentricity during rotation, so that the lathe c...

Problems solved by technology

[0002] When turning many metal parts, due to the influence of the part structure, the hydraulic rod of the lathe itself cannot be used for automatic tightening, so workers need to use a wrench to manually lock, which not only increases the clamping time, but also increases the labor intensity of the workers. Under the background of modern labor shortage, this kind of tooling cannot meet the production needs and is not popular among workers.

[0003] Especially for non-circular parts in the clamping part, ordinary tooling cannot achieve symmetrical center of weight and cannot rotate smoothly. The centrifugal force is relatively large during turning, and the workpiece is affected by the centrifugal force, which reduces the concentricity during rotation, so that the lathe can only be rotated at a low Machining at a high speed will not only damage the spindle, but also increase the wear of the tool due to the non-concentric rotation
