Balancing pilot run transmission

Abstract

The invention is concerned with a balance test run gearing, relating to a platform, a turntable, two workbenches, an inner revolving seat, a driving source, a on-off piece and a driving group. The turntable is running on the platform and the workbench with paw is symmetrically running on the turntable. The inner revolving seat is running on the platform and the driving source drives and connects with the transmission gear. The on-off piece connects with inner revolving seat in running and the driving group drives the on-off piece to separate of match with the transmission gear. When the turntable revolves, it makes the workbench to match and fix with the inner revolving seat tightly, and the driving group drives the on-off piece to separate the transmission gear. When the paw holds the workpiece tightly, the driving group drives the on-off piece to match with the transmission gear, and the driving source drives the workbench to revolve to test the balance of the holding state to paw.

Description

technical field [0001] The present invention relates to a transmission device for balanced test run, in particular to a transmission device for balanced test run with a clutch member engaged and disengaged from a transmission gear, so that the clamping of the workpiece is separated from the test run, and the workpiece can be moved before entering the processing step. Do a test run to test for balance. Background technique [0002] A lathe is an important machine tool for workpiece processing. Please refer to Fig. 1. It is one of various types of vertical lathes. The vertical lathe 9 includes a machine table 91, a cutting tool 92, two door panels 93, a turntable 94 and Two workbenches 95, the cutting tool 92 is arranged in the processing space 911 in the machine platform 91, the two door panels 93 can be opened and closed on the machine platform 91, and the workbench has a plurality of jaws 951 for clamping the workpiece, When a workbench 95 with workpieces fixed enters the ...

Problems solved by technology

[0004] However, the biggest problem with the above-mentioned structure is that the workpiece cannot be tested, that is, whether the workpiece to be processed is stably clamped by the jaws 951, it must wait for the turntable 94 to rotate the worktable 95 into the processing space 911, and the spindle drives the worktable 95 test rotation to find out, or manually rotate the test, if the spindle test run finds that the workpiece clamping is unbalanced, the worktable 95 must be turned out again and reinstalled to waste time, if the manual test is performed, it cannot be detected Slight abnormality, when the abnormality exists and the processing starts, the light workpiece will become waste, and the severe one will cause the workpiece to fly out and damage the structure or parts of the machine 91, or even hurt people
