Description
Technical field
[0001] the utility model relates to a kind of used positioning fixture of rolling stock accessory production, pneumatic rolling clamp of type in particularly a kind of side bearing mills of being used for.
Background technology
[0002] side bearing is the strength member in the railway goods train bogie, and it is installed in the bolster in every bogie, forms elastic side bearing with elastic side bearing body, side bearing wear plate, roller, Roller Shaft, adjustment backing plate and backing plate.Elastic side bearing plays interception when vehicle rollover and sideslip.Side bearing is the crucial accessory of railway goods train bogie; Each part of this product is whole rust steel part steel-casting; Complex-shaped, processing dimension is various, and the accuracy of manufacture is high; Difficulty of processing and production lot are bigger, and the version of side bearing and performance are directly connected to the operation critical speed of crawling of vehicle, the important dynamics performance indications such as coefficient, wheel off-load rate, curving performance of derailing.So whether reasonable traffic safety that directly influences the permutation lorry of its processing technology of side bearing.Original processing mode adopts earlier that type unloads workpiece again in processing one side, rotational workpieces, clamping workpiece once more, type in the processing opposite side.Clamping is wasted time and energy, and clamping precision is low, and process velocity is slow, requires all higher being not easy of dimensional requirement to guarantee that it is higher percent defective to occur, and higher to operator's competency profiling.
Summary of the invention
The utility model technical problem to be solved is to overcome the problem that the clamping that exists in the background technology is wasted time and energy, clamping precision is low, process velocity is slow; And provide a kind of side bearing mill in the pneumatic rolling clamp of type; The pneumatic rolling clamp of type in this side bearing mills is saved the clamping time and is alleviated operator's work difficulty, can enhance productivity; Guarantee crudy, suitable large batch of production.
The utility model solves its problem and can reach through following technical scheme: the pneumatic rolling clamp of type comprised base plate in this side bearing milled; Be fixedly connected reservoir on the base plate; Described reservoir top is equipped with installing plate; Between reservoir and installing plate deep groove ball bearing is housed, studdle is equipped with in the installing plate center, is rotary with adjusting nut and packing ring on the studdle; Be equipped with piston and positioning body on the base plate of reservoir one side, the locating shaft middle part that connects piston rod places on the positioning body, the perforate of piston rod subtend installing plate bottom; Installing plate top is fixed as one pressing plate and rotating clamp, workpiece, installing plate through studs, and pressing plate and rotating clamp are pressed in the two ends of workpiece respectively, are equipped with parallels between workpiece bottom margin place and installing plate; Workpiece centre is fixed with the center lever body, is equipped with the center guiding ruler between the inwall of center lever body and workpiece, and guiding ruler bottom, center places on two risers.
The utility model and above-mentioned background compared with techniques can have following beneficial effect: the pneumatic rolling clamp of type in this side bearing mills is owing to adopt said structure, and slewing equipment is clamped during the air door air intake, during the air door air draft; Slewing equipment can turn round, and confirms the angle of revolution by positioning body, has saved the clamping time; Alleviate operator's work difficulty, guaranteed the quality of side bearing, the processing accepted product percentage is high; Production efficiency is high, is fit to produce in enormous quantities.Worker, anchor clamps are once invested little, have good and economic.
Description of drawings:
Accompanying drawing 1 is the structural representation of the utility model;
Accompanying drawing 2 is vertical views of accompanying drawing 1;
Accompanying drawing 3 is structural representations of the workpiece side bearing of the utility model.
Among the figure: 1-positioning body, 2-reservoir, 3-center lever body, 4-workpiece, 5-pressing plate; The 6-studs, 7-cover, 8-packing ring, 9-adjusting nut, 10-deep groove ball bearing; The 11-base plate, 12-installing plate, 13-parallels, 14-rotating clamp, 15-riser; 16-center guiding ruler, 17-piston rod, 18-locating shaft, 19-studdle.
The specific embodiment:
To be described further the utility model below in conjunction with accompanying drawing:
Accompanying drawing 1 combines shown in Figure 2; The pneumatic rolling clamp of type comprised base plate 11 in this side bearing milled; Be fixedly connected reservoir 2 on the base plate 11, reservoir 2 tops are equipped with installing plate 12, and 12 of reservoir 2 and installing plates are equipped with deep groove ball bearing 10; Studdle 19 is equipped with in installing plate 12 centers, is rotary with adjusting nut 9 and packing ring 8 on the studdle 19; Be equipped with piston and positioning body 1 on the base plate of reservoir 2 one sides, locating shaft 18 middle parts that connect piston rod 17 place on the positioning body 1, the perforate of piston rod 17 subtend installing plates 12 bottoms, and piston rod 17 upper ends are with sheath 7; Installing plate 12 tops are fixed as one fixation clip 5 and rotating clamp 14, workpiece 4, installing plate 12 through studs 6, and pressing plate 5 and rotating clamp 14 are pressed in the two ends of workpiece 4 respectively, and workpiece 4 bottom margin places and 12 of installing plates are equipped with parallels 13; Workpiece 4 center fixation have center lever body 3, are equipped with center guiding ruler 16 between the inwall of center lever body 3 and workpiece, and guiding ruler bottom, center places on two risers 15.
