Abstract
The utility model discloses a clamp for cylinder mounting machines, which comprises a clamp seat, a main body and a locating shaft, and is characterized in that a roller holder is fixed in a hole of the main body, three uniformly distributed slots are arranged on the inner surface of the roller holder, the cross section of the bottom of each slot is a circular and smooth curve, the distance between the curve and the center of the roller holder gradually increases from one end to the other, and rollers are arranged in the slots. The utility model uses a fast clamping mechanism which clamps a non-thread surface of an oil cylinder body, and thus has the advantages of no damage to threads of oil cylinders and high efficiency of cylinder mounting compared with the prior art.
Description
(1) technical field: the utility model belongs to clamping tool, particularly a kind of vertical hydraulic jack upper cylinder half machine anchor clamps.
(2) background technology; Vertical hydraulic jack is a kind of widely used instrument that hoists, when the assembling jack cylinder, existing method is after the upper cylinder half machine has the anchor clamps of a band silk mouthful to be spun on the screw thread of oil cylinder upper end, continue rotation again with on the screw thread precession base of oil cylinder lower end and screw, the counter-rotating of upper cylinder half machine breaks away from cylinder body then, its shortcoming is fragile oil cylinder screw thread, and efficient is lower.
(3) summary of the invention: the utility model technical issues that need to address are that design does not a kind ofly damage the oil cylinder screw thread, and the high upper cylinder half machine anchor clamps of upper cylinder half efficient.Technical solution of the present utility model is such, this upper cylinder half machine includes clamping fixture seat, body and locating shaft with anchor clamps, it is characterized in that: be fixed with roller stand in the hole of body, on the roller stand inner surface, be provided with three uniform grooves, the cross section of bottom land is a smooth curve, this curve passes through to the distance at roller stand center and increases gradually, is provided with roller in the groove.The utility model adopts the quick clamping mechanism on the non-threaded surface of clamping cylinder body.Thereby have compared with the prior art and do not damage oil cylinder screw thread and the high advantage of upper cylinder half efficient.
(4) description of drawings: Fig. 1 is a structural representation of the present utility model.Fig. 2 is the A-A profile of Fig. 1.Among the figure, 1. clamping fixture seat 2. bodies 3. locating shafts 4. packing rings 5. pins 6. pins 7. roller stands 8. rollers 9. back-up rings 10. bolts
(5) specific embodiment: the utility model includes clamping fixture seat 1, body 2 and locating shaft 3, the stepped cylinder of locating shaft upper end places in the stepped hole of body, one roller stand 7 is arranged in the bottom hole of body, it is evenly equipped with three grooves, the cross section of groove is the curve of a slyness, the centre distance in this curve and hole is increased gradually by little, roller 8 is arranged in the groove, the gap of locating shaft 3 and body mider hole is greater than the wall thickness of oil cylinder, the protruding step body of locating shaft upper end is provided with the screw via hole, body is provided with and the relative screwed hole of above-mentioned screw via hole, screw links into an integrated entity locating shaft and body, and pin 5 inserts in the hole of back-up ring 9 and body, and pin 6 inserts in the hole of back-up ring and roller stand, guarantee the concentricity of body and roller stand and locating shaft, bolt 10 is worn in the screwed hole that people's back-up ring and body screw in clamping fixture seat each part is linked to be an integral body.Using method of the present utility model is, inject the locating shaft of these anchor clamps in the oil har opening and oil cylinder lower end screw thread is revolved the screwed hole of people's jack base after start the upper cylinder half machine, anchor clamps are rotated counterclockwise, roller moves to the center cylinder body is clamped the rotation of drive oil cylinder, after the screwed hole of oil cylinder and base screws, the upper cylinder half machine stops operating and the backward rotation roller unclamps cylinder body, finishes cylinder working.The utility model has upper cylinder half efficient height compared with the prior art and does not damage the advantage of oil cylinder screw thread.
Claims (1)
1, upper cylinder half machine anchor clamps, it includes clamping fixture seat, body and locating shaft, it is characterized in that: be fixed with roller stand in the hole of body, on the roller stand inner surface, be provided with three uniform grooves, the cross section of bottom land is a smooth curve, this curve passes through to the distance at roller stand center and increases gradually, is provided with roller in the groove.
