Problems solved by technology

Apparently, Option 1 and Option 2 not only occupy a large space, but also cost a lot
As for the use of machining centers, although the accuracy is easy to guarantee and the floor space is small, the input cost is very high.
Especially in the automatic line or assembly line, when inserting a machining center, it is necessary to consider a series of problems such as the delivery of parts and the addition of manipulators, and the investment is even greater.

Embodiment 1

[0017] Embodiment 1: see Figure 1-Figure 4 Positioning rotary device in. The drive shaft 1 is installed on the rotary shaft 12 and the rear cover 17 of the box with two ball bearings 2, 18. The rear end of the drive shaft 1 is equipped with a toothed belt pulley 20 powered by a driving motor, and the front end is connected with the keyway on the rear end surface of the drive shaft of the headstock. Connected to drive the headstock spindle to rotate for processing.

[0018] The back cover 17 of the box body is fixed on the box body 28 with a screw cylindrical pin, and a bolt oil cylinder 25 and a hydraulic motor 35 are installed on it through a positioning bolt. The driving gear 16 is connected with the hydraulic motor 35 by a spline, and the driving gear 16 drives the driven gear 22, the driven gear 22 is connected with the rotary shaft 12 with a key, thereby driving the rotary shaft 12 to rotate, and the rotary disc 4 is connected and fixed with the rotary shaft 12 with scr...

Embodiment 2

[0021] Embodiment 2: The accompanying drawings are not drawn, and the content is basically the same as Embodiment 1, and the similarities will not be repeated. The difference is that six spindles are evenly distributed on the end surface of the headstock, which is suitable for parts that need to be processed six times. When processing a station, the positioning rotary device drives the spindle box to rotate 60 degrees, and the latch mechanism is inserted into the positioning sleeve to realize positioning.

Abstract

The invention relates to a positioning turning device which drives in a hydraulic and mechanical combined mode and comprises a turning mechanism, a hydraulic locking releasing mechanism, a hydraulic positioning plug mechanism and a power driving mechanism, wherein a turning plate is driven by a hydraulic motor through a set of gears and is continuously turned along a same peripheral direction; when a signal is encountered, the turning is stopped, a plug cylinder is plugged, the turning plate is positioned, and then the turning plate is backward pulled and locked by a locking cylinder; and a power part transmits the power to a main bearing box which is used together with the power part through a driving shaft. The positioning turning device is used together with the main bearing box and is suitable for a special machine and an automatic moving line for repeatedly processing a same position on a workpiece in different processes. The positioning turning device has the advantages of compact structure, stability in moving, high precision, low cost and conveniences in operating and maintaining.

Description

technical field [0001] The invention relates to a positioning rotary device, in particular to a multi-station processing device with rotary, positioning, locking and power transmission. Background technique [0002] In the prior art, when processing a certain special position on the workpiece, or when the accuracy of a certain hole on the workpiece is relatively high, it often needs to be processed in multiple processes. For example, the lubricating hole of the crankshaft hole of the cylinder block is on an inclined side of the cylinder block, and the three steps of countersinking the end face of the inclined hole, drilling, and tapping are required to meet the requirements. The processing of the hole is often processed by the following schemes: scheme one is processed by three special machine tools; scheme two is processed by one machine tool horizontally arranged in three stations, and the workpiece is placed on a mobile workbench; scheme three uses a machining center. Ob...
