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 the press industry, a kind of specifically machinery, the instant safety lock locking apparatus of locking press equipment slide blocks automatically.
Background technique
At present, the various press equipment that domestic pressure machinery manufacturing company produces, its slide blocks safety lock locking apparatus main structure is to utilize the bolt-type structure 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, moving of slide blocks highly can not all peak at every turn, thereby the safety lock locking apparatus of bolt-type structure is just ineffective.And the bolt-type structure is under the situation of outage, system's decompression, and safe locking device all can lose efficacy.That is to say that bolt-type safety lock locking apparatus can only work when press equipment slide blocks is got back to topmost, other operating modes are failure state, and operator's personal safety is brought great harm.
Summary of the invention
The present invention 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 locking apparatus that has spring, lock dog structure.
Technological scheme of the present invention is that a kind of machine security Locking Device of locking immediately comprises support; Frame bottom is equipped with guide sleeve, it is characterized in that: the oil cylinder flange of left end is equipped with oil cylinder in the support, takes 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, and the spring cylinder right-hand member is equipped with the adjustment bolt, and spring cylinder is connected with right half arc lock dog through spring; A left side half arc lock dog and right half arc lock dog symmetry are installed, and 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 through the guide sleeve endoporus.Press equipment proper functioning, during the slide blocks upstream or downstream, till mechanical lock oil cylinder generation thrust promoted right half arc lock dog and drives left half arc lock dog to block indirectly through push rod, 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 be processed with special locking screw thread on left half arc lock dog and right half arc lock dog inboard and the sissy bar, can the slide block sissy bar embraced, lock.Outage or the working principle during system's decompression are identical with it, thereby guarantee under any operating mode, and the safety lock locking apparatus all can be automatically, immediately with the slide block locking, guarantee operator's personal safety 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, safe safety lock locking apparatus.
Description of drawings
Fig. 1 is a structural front view of the present invention, and the accompanying drawing that makes an abstract.
Fig. 2 is a plan view of the present invention.
Fig. 3 is a front view of the present invention.
In the drawings, 1 oil cylinder, 2 supports, 3 oil 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 bolts, 12 guide sleeves, 13 blocks.
Embodiment
Below in conjunction with accompanying drawing and embodiment, the present invention is further specified.
As shown in the figure, guide sleeve 12 is equipped with in support 2 bottoms, and the oil cylinder flange 3 of left end is equipped with oil cylinder 1 in the support 2; Take over a business 4 and be connected with oil cylinder 1, take over a business 4 four jiaos and four push rods 6 are housed respectively and pass 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, and the spring cylinder flange 9 of support 2 right parts is equipped with spring cylinder 10, and spring cylinder 10 right-hand members are equipped with adjustment bolt 11; Spring cylinder 10 is connected with right half arc lock dog 8 through spring; A left side half arc lock dog 7 is installed with right half arc lock dog, 8 symmetries, and 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 through guide sleeve 12 endoporus.Press equipment proper functioning, during the slide blocks upstream or downstream, mechanical lock oil cylinder 1 produces thrust through the right half arc lock dog 8 of push rod 6 promotions and till driving left half arc lock dog 7 to block 13 indirectly, and this moment, left half arc lock dog 7 and right half arc lock dog 8 were in open configuration.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 is pushed to the locking closed state with left half arc lock dog 7.Because left half arc lock dog 7 is processed with special locking internal thread with right half arc lock dog 8 inboards, can the slide blocks sissy bar embraced, lock.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 operator's personal safety to greatest extent.
