Problems solved by technology

During processing, the first clamping device, the first clamping device, the first turret, the second turret and the main shaft cooperate to perform rough turning and finishing turning on the long-axis workpiece, and use the first turret and the second turret to The two turrets process both sides of the long-axis workpiece at the same time to offset the stress generated by the turret on the workpiece during single-sided processing. At the same time, the added clamping device can ensure that the long-axis workpiece will not shake and solve the vibration during processing. The low precision of the machined parts and the influence of poor roughness lead to a decrease in the pass rate. Using one machine tool can complete the entire process of a long-axis workpiece, which can avoid multiple clamping and affect the accuracy.

Embodiment 1

[0034] Example 1 as figure 1 As shown, a long-axis turning machine tool includes a bed 11, a column is arranged on the bed, a spindle 11 is arranged on the column, and a driving member 12 is arranged on the rear side of the column. The driving member 12 is a servo motor, and the driving member 12 is synchronously The belt drives the main shaft 11 to rotate, and the other side of the column is provided with a first movable hole 13, and a top device 2 is movable in the first movable hole 13. The top device 2 is mainly used to assist the main shaft 11 to clamp the workpiece, preventing the The end of the workpiece shakes, which affects the machining accuracy.

[0035] The first turret 3 and the second turret 4 are arranged on the column of the bed 1, and the first turret 3 and the second turret 4 are vertically distributed and arranged on the upper and lower sides of the clamped workpiece. The first clamping device 5 and the second clamping device 9 are also movable on the colum...

Embodiment 2

[0049] Such as Figure 11-Figure 12 As shown, other structures on the bed are the same as those in Embodiment 1, the difference is that Embodiment 2 does not have a retractable top device 2, and replaces the top device 2 with a rotating tailstock. The specific structure is as follows: one end of the column is movable Three slide rails, a rotary tailstock 111 is movably arranged on the third slide rail, and a third driving part 112 is arranged on the column, and the third driving part 112 controls the movement of the rotary tailstock 111 through a screw rod.

[0050] The rotating tailstock 111 has other functions besides ensuring the basic function of supporting the workpiece, so the rotating tailstock 111 must have a good bearing capacity, so based on this requirement, the turret seat and the turret seat handle are designed The whole body of the rotary tailstock 111 is wrapped, and only the tool part is reserved on the outside for processing the workpiece, which can greatly in...

Embodiment 3

[0052] Such as Figure 13 As shown, the technical solution of embodiment 3 is generally the same as the structure of embodiment 1 and embodiment 2, the difference is that a movable sub-spindle 135 is set on the bed, and the movement mode of the sub-spindle 135 is the same as the horizontal direction of the top device 2. The movement method is the same, both of which are driven by the motor screw to control the lateral movement of the sub-spindle 135. The application of the sub-spindle 135 is that when the processed workpiece is too thin, it can be fixed by the sub-spindle 135, which can be fixed more firmly. It looks simple and convenient.

Abstract

The invention belongs to the technical field of long shaft type part machining equipment, and particularly relates to a long-shaft turning machine tool. The long-shaft turning machine tool comprises amachine tool body, the machine tool body is provided with a main shaft used for driving a workpiece to rotate, the portion, on one side of the main shaft, of the machine tool body is provided with afirst clamping device and a second clamping device which are used for clamping the workpiece, a first tool turret and a second tool turret are arranged on the machine tool body and distributed on thetwo sides of the workpiece, and in the main shaft workpiece rotating process, the first clamping device, the second clamping device, the first tool turret and the second tool turret cooperate with oneanother to machine the workpiece; and the machine tool body is movably provided with a rotating tailstock used for fixing multiple tools and tips, and the tips of the rotating tailstock are movably connected with a central hole of the workpiece in an abutting manner. The long-shaft turning machine tool has the advantages that the machining precision is high, the machining rate is high, and one device can complete all processes for machining a long-shaft part.

Description

technical field [0001] The invention belongs to the technical field of long-axis parts processing equipment, and in particular relates to a long-axis turning machine tool. Background technique [0002] In the processing and production of long axis parts, due to the particularity of its processing, rotation processing is generally used, and one end of the long axis is fixed, and the other end is suspended for processing, which leads to the fact that the long axis will be smaller during processing. Amplitude up and down or back and forth shaking, and because of processing reasons, the tool on the turret will vibrate during processing, and the precision of the processed parts is low, and the roughness is poor; at the same time, processing long-axis parts requires multiple different machines. For example, the rough turning of the long shaft should be carried out first to make the surface neat, confirm the center hole, etc., and then be clamped to the finish car for subsequent pr...
