Abstract
The present invention discloses a hand-protecting device for machine tool with reciprocating movement. It includes a hand-shifting bar, the static portion of machine tool is equipped with a rack bar, the hand-shafting bar is placed on a rotation shaft and is positioned on the outside portion of motion portion of punching machine, and between the rack bar and rotation shaft a driving device formed from driving gear or driving band is set.
Description
Technical field
The present invention relates to a kind of machine tool safety protection device, specifically relate to the hand guard device of reciprocating lathe such as punch press, injection machine, hydraulic machinery etc.
Background technique
Existing reciprocating machining equipment such as punch press etc. must impose power to the worktable of place work piece, and the operator will put and the position adjustment to workpiece, therefore do not have the punch press of protective equipment, and very easily the drift that is descended is at a high speed cut pressure and sustained a severe injury.In order to solve above-mentioned safety problem, people have been installed safety installations additional on lathe, yet general safety installations is the stopping device that punch press is set, as stop switch, punch press switch by photoelectric control etc., but only control the punch press switch and often do not reach ideal effect and since punch press high speed inertia, also need have a bigger punch press braking device just can reach the safety protection effect.Someone has invented hand protector, as application number is 99243324, the applying date is on September 20th, 1999, denomination of invention is the patent application of a kind of punch press with hand protector, mainly constitute by switch, the poker device of controlling its work by switch, poker device is fixed in punch press worktable side, switch can be arranged on punch press foot treadle above, also can be arranged on punch press foot treadle below, the position of switch is to set like this, when the punch press foot treadle down moves but before also not touching the punch ram switch, switch is touched.This patent adopts the poker device that installs additional by switch control, can set the motion formula of punch press, equal in course of working, to have added the hand preface one, the follow procedure operation can be played certain protection, but cause the reduction of working efficiency, and the operator controls bad coordination to the interlock between switch and the foot treadle, and the action that drift dashes poker device down at a high speed also has influence.
Summary of the invention
Purpose of the present invention provides a kind of simple in structure in order to solve above-mentioned deficiency exactly, can be by the punch press hand guard device that fixedly motion formula is operated automatically, operational reliability is high.
The present invention realizes above-mentioned purpose by following technical proposals:
The hand guard device of reciprocating lathe of the present invention comprises and dials hand lever, is provided with tooth bar in the stationary part of lathe, dials hand lever and is arranged on the rotatingshaft and is positioned at punch press motion portion lateral part, between tooth bar and the rotatingshaft transmission device is set.
Described transmission device is for being provided with driving gear formation being provided with on the rotatingshaft between gear, tooth bar and the rotatingshaft gear.
The gear of described transmission device for being meshed with tooth bar in the setting of tooth bar side, gear and transmission shaft connect and compose by driving belt.
The invention has the advantages that:
Adopt fixedly linkage pattern, mechanical motion portion such as drift and tooth bar to-and-fro motion, before the minimum point of drift whereabouts, as 50-60mm, the hand lever lowest point of rotation handle of dialling that is on the drift is pushed aside, can effectively avoid accident to take place; Simple in structure, to install easily, cost is low.
Description of drawings
The invention will be further described below in conjunction with the drawings and specific embodiments:
Fig. 1 is one embodiment of the invention plane structure schematic representation;
Fig. 2 is Fig. 1 embodiment's a side direction structural representation;
Fig. 3 is the transmission structures schematic representation of another embodiment of the present invention.
Specific embodiment
As shown in Figure 1 and Figure 2, embodiments of the invention are example with the punch press, comprise dialling hand lever 1, dial hand lever 1 and are arranged on the rotatingshaft 7 and are positioned at punch press motion portion lateral part, are provided with tooth bar 6 in the stationary part of punch press, between tooth bar 6 and the rotatingshaft 7 transmission device are set; The surface of pulling out hand lever 1 is provided with soft cover, and this transmission device is for being provided with a plurality of driving gears 5 formations being provided with on the rotatingshaft 7 between gear, tooth bar 6 and the rotatingshaft gear 4, and driving gear 5 all is arranged on punch press motion portion; Rotatingshaft is arranged on the neutral position of punch press motion portion.
As shown in Figure 3, transmission device of the present invention is the gear that is meshed with tooth bar 6 in tooth bar 6 side settings, and gear and transmission shaft connect and compose by driving belt 5, and this driving belt 5 can adopt cingulum.
Transmission device is converted to rotatablely moving of rotatingshaft 7 with the to-and-fro motion of punch press drift 2 by tooth bar 6, transmission device, by velocity ratio is set, when drift 2 is positioned at peak, pull out hand lever 1 and also be in higher position, when drift 2 drops near minimum point, pull out hand lever 1 and on table top 3, rotated and stirred, so go round and begin again, thereby can push the hand on the worktable 3 when punch press is worked aside, the accident that prevents takes place, and guarantees operator's safety.
The present invention can be used for reciprocating machining equipment, as punch press, injection machine, hydraulic machinery etc.
