Description

A kind of machining tooling for curved surface conical cylinder

technical field

The invention relates to a machining tool, in particular to a machining tool used for finishing the cast blank conical cylinder.

Background technique

The shape of the special-shaped curved conical cylinder with fins is a conical surface, and there are four fins evenly distributed on one side of the small end. The inner cavity is distributed with a large number of bosses and hole seats with different spatial positions and shapes. The shell blank of the special-shaped curved conical cylinder is a casting, and the processing content in the shell cavity is relatively complicated, such as milling large planes, small planes, step planes, making holes on planes, holes on arcuate surfaces, etc. During machining, the vertical rotary table clamps the small end, and the workpiece needs to be rotated once for each part of the machining. The flat top supports the outer circular surface of the large end of the workpiece. When the end is at a horizontal position, there is a problem of large adjustment errors, especially when the large end of the conical cylinder is prone to shake during processing, resulting in a high rate of defective products in processing.

Detailed ways

The present invention is described in detail below in conjunction with accompanying drawing:

A kind of machining tooling for a curved conical cylinder, comprising a worktable 1 and a curved conical cylinder 6, on which a rotary table support 2 and a two-way clamp support seat 7 are arranged respectively, on the rotary worktable A vertical rotary table 3 is provided on the support 2, and a bidirectional clamp is provided on the support seat 7 of the bidirectional clamp. The right end of the vertical rotary table 3 is connected to the three-jaw chuck 4 through the flange 5. Together, rear support rollers 13 are provided on the rear clamping block 8 of the bidirectional clamp, and front support rollers 15 are provided on the front clamping block 14 of the bidirectional clamp. The large mouth end of the curved tapered cylinder 6 is arranged between them, and the three-jaw chuck 4 is clamped in the small mouth end of the curved tapered cylinder 6, on the working table 1 on the side of the bidirectional clamp support seat 7 The pressing assembly 9 provided with the clamp support seat 7 is provided with a door-shaped frame 10 on the work surface 1 on both sides of the large mouth end of the curved tapered cylinder body 6, and a sliding door frame is arranged on the top beam of the door-shaped frame 10. The sleeve 16 is provided with a slider 19 in the sliding sleeve 16, and the bottom end of the slider 19 is connected with a slider pressing roller 18, and the slider pressing roller 18 is connected to the upper end surface of the large mouth end of the curved tapered cylinder 6 Together, a screw hole is provided on the top plate of the sliding sleeve 16, and a bolt 17 is screwed in the screw hole, and the lower end of the bolt 17 is connected with the top surface of the slider 19; A fixed pressure plate 21 is arranged inside, and the pressure plate fixing bolt 22 is connected with the vertical rotary table 3 through the fixed pressure plate 21 .

The drive rocker 11 of the three-jaw chuck is set on the vertical rotary table 3, the drive handle 12 of the clamping block is set on the two-way clamp, and the top wire 20 is set between the slider 19 and the sliding sleeve 16 .

By rotating the drive handle 12 of the clamping block, the back support roller 13 and the front support roller 15 are controlled to open or close, so as to achieve a slight adjustment of the height of the large mouth end of the curved tapered cylinder body 6, so that the large mouth of the curved surface tapered cylinder body 6 End center line coincides with the small mouth end center line of curved surface tapered cylinder body 6. In order to overcome the shaking of the large mouth end of the curved tapered cylinder body 6 during processing, the slider pressing roller 18 is reliably connected to the upper surface of the large mouth end of the curved surface tapered cylinder body 6 by adjusting the bolt 17, and the slider The top screw 20 provided between the block 19 and the sliding sleeve 16 is tightened to prevent the bolt 17 from loosening.
