Abstract
An instant-locking mechanical safety locking device comprises a support, and a guide sleeve is mounted at the bottom of the support. The instant-locking mechanical safety locking device is characterized in that an oil cylinder is mounted on an oil cylinder flange at the inner left of the support, a top disk is connected with the oil cylinder, four top rods are mounted at four corners of the top disk respectively, the four corners of the top disk penetrate through a left semi-arc locking block which is mounted in the support, a guide plate is mounted on the upper portion of the left semi-arc locking block, a spring cylinder is mounted on a spring cylinder flange on the right end face of the support, an adjusting bolt is mounted at the right end of the spring cylinder which is connected with a right semi-arc locking block through a spring, the left semi-arc locking block and the right semi-arc locking block are symmetrically mounted, the right ends of the four top rods contact with the right semi-arc locking block, and a stopper is mounted on the lower portion of the right semi-arc locking block. By the aid of the instant-locking mechanical safety locking device, a slider of a press machine can be instantly locked at any position each time when the slider moves and the slider is automatically locked under conditions of scram power loss and oil loss. The problem that a slider of the existing press machine cannot be automatically locked at any position at any time is solved, and the mechanical safety locking device is suitable for various press machines.
Description
Technical field
The utility model relates to the press industry, specifically the safety locking device of a kind of machinery, instant automatic locking press equipment slide blocks.
Background technique
At present, the various press equipment that domestic pressure machinery manufacturing company produces, its slide blocks safety locking device main structure are to utilize the socket type structural of hydraulic oil cylinder driving to come the slide blocks of locked-in stress machinery.This kind structure can only be worked as slide blocks, and (as topmost) could be by locking in fixing position, and still in actual production, the movement of slide blocks highly can not all peak at every turn, thereby the safety locking device of socket type structural is just ineffective.And, socket type structural in the situation that the outage, system's decompression, safe locking device all can lose efficacy.That is to say, the bolt-type safety locking device can only work when press equipment slide blocks is got back to topmost, and other operating modes are failure state, and operator's personal safety is brought great harm.
Summary of the invention
The utility model for solve present press equipment slide blocks can not be in any position by the problem of locking at any time, design a kind of automatic locking device with spring, lock block structure.
The technical solution of the utility model is, a kind of machine security Locking Device of immediately locking, comprise support, frame bottom is equipped with guide sleeve, it is characterized in that: the cylinder flange of left end is equipped with oil cylinder in the support, take over a business with oil cylinder to be connected, take over a business four jiaos and four push rods are housed respectively and pass left half arc lock dog, left half arc lock dog is installed in the support, and guide plate is equipped with on top, the spring cylinder flange of support right part is equipped with spring cylinder, the spring cylinder right-hand member is equipped with the adjustment bolt, and spring cylinder is connected with right half arc lock dog by spring, and left half arc lock dog and right half arc lock dog are symmetrical to be installed, four push rod right-hand members contact with right half arc lock dog, and block is equipped with in right half arc lock dog bottom.
During work, the machine security Locking Device is positioned on the upper table surface of press equipment, the special locking screw thread of slide blocks sissy bar upper end processing certain-length, sissy bar penetrates by the guide sleeve endoporus.Press equipment normal operation, during the slide blocks upstream or downstream, the mechanical lock oil cylinder produces thrust and promotes right half arc lock dog by push rod and indirectly drive left half arc lock dog till the block, and this moment, left half arc lock dog and right half arc lock dog were in open configuration.When slide blocks when stop suddenly in arbitrary position in working stroke, mechanical lock cylinder oil system pressure release this moment, oil cylinder loses thrust, and the spring in the spring cylinder then produces thrust, and left and right sides two halves arc lock dog is pushed to the locking closed state.Owing to being processed with special locking screw thread on left half arc lock dog and right half arc lock dog inboard and the sissy bar, the slide block safety pull bar can being embraced, locked.Outage or the working principle during system's decompression are identical with it, thereby guarantee under any operating mode, and safety locking device all can be automatically, immediately with the slide block locking, guarantee to greatest extent operator's personal safety.
Technique effect of the present utility model is, adopts above-mentioned technological scheme, can realize a kind of easy and simple to handle, safe safety locking device.
Description of drawings
Fig. 1 is structural front view of the present utility model, and the accompanying drawing that makes an abstract.
Fig. 2 is plan view of the present utility model.
Fig. 3 is front view of the present utility model.
In the drawings, 1 oil cylinder, 2 supports, 3 cylinder flanges, 4 are taken over a business, 5 guide plates, 6 push rods, 7 left half arc lock dogs, 8 right half arc lock dogs, 9 spring cylinder flanges, 10 spring cylinders, 11 adjust bolts, 12 guide sleeves, 13 blocks.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further specified.
As shown in the figure, guide sleeve 12 is equipped with in support 2 bottoms, the cylinder flange 3 of support 2 interior left ends is equipped with oil cylinder 1, taking over a business 4 is connected with oil cylinder 1, taking over a business 4 four jiaos is equipped with respectively four push rods 6 and passes left half arc lock dog 7, left half arc lock dog 7 is installed in the support 2, guide plate 5 is equipped with on top, the spring cylinder flange 9 of support 2 right parts is equipped with spring cylinder 10, spring cylinder 10 right-hand members are equipped with adjusts bolt 11, and spring cylinder 10 is connected with right half arc lock dog 8 by spring, left half arc lock dog 7 and right half arc lock dog, 8 symmetrical installations, four push rod 6 right-hand members contact with right half arc lock dog 8, and block 13 is equipped with in 8 bottoms of right half arc lock.
During work, the machine security Locking Device is positioned on the upper table surface of press equipment, the special locking screw thread of slide blocks sissy bar upper end processing certain-length, sissy bar penetrates by guide sleeve 12 endoporus.Press equipment normal operation, during the slide blocks upstream or downstream, mechanical lock oil cylinder 1 produces thrust and promotes right half arc lock dog 8 by push rod 6 and indirectly drive left half arc lock dog 7 till the block 13, and this moment, left half arc lock dog 7 was in open configuration with right half arc lock dog 8.When slide blocks when stop suddenly in arbitrary position in working stroke, mechanical lock oil cylinder 1 oil-way system pressure release this moment, oil cylinder 1 loses thrust, and the spring in the spring cylinder 10 then produces thrust, and the right side half arc lock dog 8 and left half arc lock dog 7 are pushed to the locking closed state.Because left half arc lock dog 7 is processed with special locking internal thread with right half arc lock dog 8 inboards, the slide blocks sissy bar can be embraced, is locked.Outage or the working principle during system's decompression are identical with it, can guarantee under any operating mode, and the machine security Locking Device all can be automatically, immediately with the slide block locking, guarantee to greatest extent operator's personal safety.
