Abstract

The utility model relates to a special machine tool for car wheels, in particular to a roller seamer for the process of the flat wheel felloe. The roller seamer comprises a body, a C-shaped frame, a fastening device, an idler wheel, and a hydrocylinder, which is characterized in that the C-shaped frame is fixed to the bracket which can glide along the guideway and contact roller adjusting gears are arranged on the top of the C-shaped frame, the contact roller and the lower contact roller are provided on the foreside of the C-shaped frame. The fastening device comprises a clamp air cylinder connected with a lever, which is connected with the upper clamp check and the lower clamp check. When processing the workpieces, the workpieces can be set on the lower clamp, then the air cylinder will drive the lever to hold the workpieces tightly and the hydrocylinder propels the C-shaped frame which will steer and push the rolling heads to roll through 8 needle bearings on its flanks. The two rolling heads can be adjusted through the adjusting gears above.

Description

Dull and stereotyped wheel rim roll extrusion welding machine

Technical field

The utility model relates to a kind of wheel special purpose machine tool, especially for the roll extrusion welding machine of dull and stereotyped wheel rim processing.

Background technology

At present, mostly be greatly for the machining tool of rim for automobile wheel in the machining manufacturing and dig slag, roll extrusion, cut-out integrative-structure, in process, planing tool lays respectively in the two hinged crossbeams up and down, do different institutional adjustments according to the thick need of different material,, dig between slag, the roll extrusion and can produce interference because machining tool is structure as a whole, cause the plane slag unclean, the roll extrusion injustice.

Summary of the invention

For overcoming above-mentioned weak point of the prior art, the utility model provides a kind of dull and stereotyped wheel rim roll extrusion welding machine, fuselage and roller fixed support, adopt the double C-type framework, guarantee stiffness of fuselage, adopt the lever clamp mechanism, expect that thick variation fuselage need not to regulate, thereby make the commissure smooth.

The utility model is realized with following technical scheme: described dull and stereotyped wheel rim roll extrusion welding machine comprises: lathe bed, C type framework, clamp mechanism, roller, oil cylinder, it is characterized in that: C type frame fixation is in can be along on the support of guide rail movement, the upper unit of C type framework has last contact roller guiding mechanism, and the anterior device of C type framework has last contact roller, following contact roller; Described clamp mechanism comprises the clamping cylinder and clamps cylinder lever that is connected and the upper clamping block that is connected with lever, following clamp bracket.

The utility model has the advantages that: this machine fuselage and roller fixed support adopt the double C-type frame mechanism, good rigidity, and roll extrusion is smooth, has overcome linkwork and has been easy to the shortcoming that becomes capable; Adopt the lever clamp mechanism, expect that thick variation need not to regulate, improved operating efficiency.

Among the figure: 1, lathe bed, 2, C type framework, 3, clamp mechanism, 4, roller, 5, oil cylinder, 6, following contact roller, 7, go up contact roller, 8, go up contact roller and adjust structure, 9, C type framework, 10, roller bearing, 11, clamp cylinder, 12, lever, 13, upper clamping block, 14, clamp bracket down.

The specific embodiment

As shown in Figure 4, C type frame fixation is in can be along on the support of guide rail movement, hydraulic oil cylinder driving, and support slides by polygon four needle bearings, and the main effect of C framework is to stop the skew of roll extrusion power and the skew of the roll extrusion size that causes thus.

As shown in Figure 7, clamping claw is fixed in the lathe bed external part, is positioned at the weld seam two ends, and hydraulic-driven adopts lever clamp mechanism, expects that thick variation need not to regulate.

Workpiece adds man-hour, at first workpiece is placed on down on the clamp bracket, and the cylinder ventilation is by the lever clamping work pieces, and oil cylinder promotes C type framework, and C type framework leads by 8 needle bearings in both sides, drives rolling wheel and carries out roll extrusion forward.Two rolling wheels can be regulated by top adjustment structure.

Claims (1)

1, a kind of dull and stereotyped wheel rim roll extrusion welding machine, comprise lathe bed (1), C type framework (2), clamp mechanism (3), roller (4), oil cylinder (5), it is characterized in that: C type frame fixation is in can be along on the support of guide rail movement, the upper unit of C type framework has last contact roller guiding mechanism (8), and the anterior device of C type framework has last contact roller (7), following contact roller (6); Described clamp mechanism comprises clamping cylinder (11) and clamps cylinder lever (12) that is connected and the upper clamping block that is connected with lever (13), following clamp bracket (4).
