Abstract
The invention discloses a mechanical safety locking device capable of locking instantaneously. The mechanical safety locking device comprises a bracket, wherein a guide sleeve is arranged at the bottom of the bracket. The mechanical safety locking device is characterized in that an oil cylinder is arranged on an oil cylinder flange at the inner left end of the bracket; a top tray is connected with the oil cylinder; four carrier rods are respectively arranged at the four corners of the top tray, and pass through a left semi-arc locking piece; the left semi-arc locking piece is arranged in the bracket; a guide plate is arranged on an upper part of the left semi-arc locking piece; a spring cylinder is arranged on a spring cylinder flange on the right end part of the bracket; an adjusting bolt is arranged at the right end of the spring cylinder; the spring cylinder is connected with a right semi-arc locking piece through a spring; the left semi-arc locking piece and the right semi-arc locking piece are arranged symmetrically; the right ends of the four carrier rods are contacted with the right semi-arc locking piece; and a chock block is arranged on the lower part of the right semi-arc locking piece. According to the device, a slide block can be locked instantaneously at any position after every action of the slide block of a pressing machine, and the slide block is locked automatically under the situation that a hydraulic system or an electrical appliance system fails, loses power in an emergency stop way and loses oil. The problem that a slide block of the conventional pressing machine cannot be locked automatically at any position at any time is solved, and the mechanical safety locking device is suitable for pressing machine equipment of various types.
Description
Technical field
The present invention relates to 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 is the slide blocks utilizing the socket type structural of hydraulic oil cylinder driving to carry out locked-in stress machinery.This kind of structure can only work as slide blocks could by locking in fixing position (as topmost), but in actual production, the movement of slide blocks highly can not all peak at every turn, and thus the safety locking device of socket type structural is just ineffective.Further, socket type structural is when power-off, system decompression, and safe locking device all can lose efficacy.That is, 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, bring great harm to the personal safety of operator.
Summary of the invention
The present invention solves current press equipment slide blocks in any position by the problem of locking at any time, to design a kind of automatic locking device with spring, lock block structure.
Technological scheme of the present invention is, a kind of can the machine security Locking Device of locking immediately, comprise support, frame bottom is equipped with guide sleeve, it is characterized in that: in support, the cylinder flange of left end is equipped with oil cylinder, take over a business and be connected with oil cylinder, take over a business corner four push rods are housed respectively and pass left half arc lock dog, left half arc lock dog is installed in support, guide plate is equipped with on top, the spring cylinder flange of support right part is equipped with spring cylinder, spring cylinder right-hand member is equipped with adjustment bolt, spring cylinder is connected with right half arc lock dog by spring, left half arc lock dog and right half arc lock dog symmetry are installed, four push rod right-hand members contact with right half arc lock dog, block is equipped with in right half arc lock dog bottom.
During work, be positioned over by machine security Locking Device 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 is penetrated by guide sleeve endoporus.Press equipment normally works, and during slide blocks upstream or downstream, mechanical lock oil cylinder produces thrust and promotes right half arc lock dog by push rod and indirectly drive left half arc lock dog to block, and now left half arc lock dog and right half arc lock dog are in open configuration.When in working stroke, any position stops suddenly slide blocks, now mechanical lock cylinder oil system pressure release, oil cylinder loses thrust, and the spring in spring cylinder then produces thrust, and left and right two halves arc lock dog is pushed to locking closed state.Due to inside left half arc lock dog and right half arc lock dog and sissy bar is processed with special locking screw thread, slide block safety pull bar can be embraced, lock.Working principle when power-off or system decompression is identical with it, thus guarantees under any operating mode, and safety locking device all can automatically, immediately by slide block locking, guarantee the personal safety of operator to greatest extent.
Technique effect of the present invention is, adopts above-mentioned technological scheme, can realize a kind of easy and simple to handle, safety locking device that Security is high.
Accompanying drawing explanation
Fig. 1 is structural front view of the present invention, and the accompanying drawing that makes an abstract.
Fig. 2 is plan view of the present invention.
Fig. 3 is front view of the present invention.
In the drawings, 1 oil cylinder, 2 supports, 3 cylinder flanges, 4 take 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 adjustment bolt, 12 guide sleeves, 13 blocks.
Embodiment
Below in conjunction with drawings and Examples, the present invention is further described.
As shown in the figure, guide sleeve 12 is housed bottom support 2, in support 2, the cylinder flange 3 of left end is equipped with oil cylinder 1, take over a business 4 to be connected with oil cylinder 1, take over a business 4 four jiaos four push rods 6 are housed respectively and pass left half arc lock dog 7, left half arc lock dog 7 is installed in support 2, guide plate 5 is equipped with on top, the spring cylinder flange 9 of support 2 right part is equipped with spring cylinder 10, spring cylinder 10 right-hand member is equipped with adjustment bolt 11, spring cylinder 10 is connected with right half arc lock dog 8 by spring, left half arc lock dog 7 is installed with right half arc lock dog 8 symmetry, four push rod 6 right-hand members contact with right half arc lock dog 8, right half arc is locked 8 pieces of bottoms and block 13 is housed.
During work, be positioned over by machine security Locking Device 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 is penetrated by guide sleeve 12 endoporus.Press equipment normally works, and during 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 till indirectly driving left half arc lock dog 7 to block 13, now left half arc lock dog 7 is in open configuration with right half arc lock dog 8.When in working stroke, any position stops suddenly slide blocks, now mechanical lock oil cylinder 1 oil-way system pressure release, oil cylinder 1 loses thrust, and the spring in spring cylinder 10 then produces thrust, and right half arc lock dog 8 and left half arc lock dog 7 are pushed to locking closed state.Owing to being processed with special locking internal thread inside left half arc lock dog 7 and right half arc lock dog 8, slide blocks sissy bar can being embraced, lock.Working principle when power-off or system decompression is identical with it, can guarantee under any operating mode, and machine security Locking Device all can automatically, immediately by slide block locking, guarantee the personal safety of operator to greatest extent.
