Abstract

The utility model discloses a fixture for processing welding grooves of the spherical heads relating to a lathe fixture. The aim of the utility model is to provide a fixture to process welding grooves of the spherical heads. The fixture can process the grooves of the head the diameter of which is more than 3100mm on the Phi3500mm vertical lathe. The technical proposal of the utility model is that: the utility model provides a fixture used to process welding grooves of the spherical heads, wherein, an adjusting fixture is arranged on the lathe stand; three cushion blocks are evenly positioned on the surface of the lathe stand; two bolts are arranged in the bolts holes of the blocks; the bolts heads are smoothly arranged in a T-shaped slot; a support plate is positioned on the surface of the lathe stand between the evenly positioned cushion blocks; two bolts are arranged in the bolts holes of the support plate; the bolts heads are smoothly arranged in the T-shaped slot of the lathe stand; a center positioned on the support plate is connected with the end surface of the head; the length of both the movable blocks in the adjusting fixture and the fixture block matches with the diameter of the head. The utility model is applied for the small lathe to process the heads with large diameter.

Description

The anchor clamps of processing dome head bevel for welding

Technical field:

The utility model relates to a kind of turning attachment, particularly a kind of anchor clamps of processing the dome head bevel for welding.

Background technology:

Be welded with adapter on the general dome head, thereby need process bevel for welding in the place, aperture, adapter hole on end socket, when the end socket diameter greater than 3100mm (as φ 3400mm), for the enterprise that φ 3500mm vertical lathe is only arranged, then can't process the groove of the above big end socket of φ 3100mm.

Summary of the invention:

The purpose of this utility model provides a kind of anchor clamps of processing the dome head bevel for welding, can process the groove of diameter greater than the 3100mm end socket on the upright bed of φ 3500mm with these anchor clamps.The technical solution of the utility model is, a kind of anchor clamps of processing the dome head bevel for welding, comprise the alignment jig on the Lathe bench, it is characterized in that: uniform at least three cushion blocks of work top, two bolts place in the bolt hole of cushion block, the bolt head cunning fits in the T type groove in the workbench, on the work top between the above-mentioned uniform cushion block, be provided with gripper shoe, two bolts place the bolt hole of gripper shoe, the bolt head cunning fits in the T type groove of workbench, gripper shoe is provided with and toply contacts with the end face of end socket, and the diameter of the movable block in the alignment jig and the length of fixture block and end socket matches.Uniform four cushion blocks and four are top on the work top.The utility model has enlarged the range of work of vertical lathe because a kind of anchor clamps of fixed seal head are provided, thereby has the advantage of the big end socket groove of processing on little vertical lathe compared with the prior art.

Description of drawings:

Fig. 1 is a vertical view of the present utility model, and Fig. 2 is the A-A profile of Fig. 1, and Fig. 3 is the B-B profile of Fig. 1, and Fig. 4 is the C-C profile of Fig. 1, and Fig. 5 is the E-E profile of Fig. 3.

The specific embodiment:

In conjunction with above accompanying drawing the utility model is described in detail, for groove with the place, adapter hole on the above dome head of existing φ 3500mm vertical lathe processing φ 3400mm, utilize dovetail groove on the vertical lathe workstation face uniform four cushion blocks 5 on workbench, the length of this cushion block can be determined (referring to Fig. 3) according to the diameter of end socket.In order to strengthen rigidity of support to the end socket end face, the vibrations of workpiece when avoiding the turning groove, between four cushion blocks 5, respectively be provided with a gripper shoe 4, this gripper shoe is fixed on the work top with the T-slot of bolt and workbench, and gripper shoe is provided with top 7 contact with the end face of end socket 8 (referring to Fig. 2).The utility model can utilize the groove of existing φ 3500mm vertical lathe processing diameter for the large-sized end enclosure below the 4500mm, and the expense of big vertical lathe and the difficulty and the expense of external coordination transportation are purchased in saving.

Claims
