Description
Technical field:
The utility model relates to a kind of bearing grinder, prevents when relating in particular to a kind of processing thin-walled bearing products that bearing ring is out of shape because of impulsive force, improves the spring adjustable type fixture for grinding machine of machining accuracy.
Background technology:
In the prior art, top formula oil cylinder pushing upper roller clamping work pieces after general the employing, grinding machine is when grinding microminiature or thin wall type bearing ring, because rear top formula oil cylinder push-tight power is difficult to adjust to accurate dynamics, and top formula oil cylinder pushing upper roller has impulsive force when clamping work pieces afterwards, can cause the original circularity of bearing ring destroyed, directly causes the crudy of bearing ring, affect product quality and production efficiency, directly bring economic loss to enterprise.
The utility model content:
The utility model is for the deficiencies in the prior art, provides a kind of bearing grinder to affect the spring adjustable type of bearing machining precision techniques difficult problem fixture for grinding machine because the clamping impulsive force causes being out of shape when grinding thin-wall bearing product.
For realizing the above object, the technical solution adopted in the utility model is:
A kind of spring adjustable type fixture for grinding machine is by capable of regulating oil cylinder, fixed support, small extension spring, fork, balance nut, mention screw, stage clip, threaded adjusting inner sleeve, threaded adjusting overcoat, Oscillating lever bearing, the headstock, rear bearing block, upper roller, bottom roller, round pin, screw thread, bottom roller seat and form; It is characterized in that: capable of regulating oil cylinder is installed on the fixed support, and small extension spring is between fixed support and fork, and an end is connected with fixed support, and the other end is connected with fork; Fork left end position is provided with screw thread, and balance nut is sleeved on the fork left end and establishes on the threaded position; Stage clip is installed in the threaded adjusting inner sleeve, and the threaded adjusting inner sleeve is installed in the threaded adjusting overcoat, mentions screw and passes the rod end that stage clip is fixed on capable of regulating oil cylinder, and the threaded adjusting overcoat is installed in the middle part of fork by round pin; Fork utilizes the swing seat bearing to be fixed on the headstock, and swings take Oscillating lever bearing as leverage points and to realize the action of material folding and discharging; Upper roller is installed in the fork right-hand member, and bottom, headstock right side is equipped with the bottom roller seat, and bottom roller is installed on the bottom roller seat, and rear bearing block is screwed on the headstock right flank; Piece-holder is in the middle of upper bottom roller and rear bearing block.
But described capable of regulating oil cylinder can replace with adjusting cylinders or with servo leading screw.
Described threaded adjusting inner sleeve and threaded adjusting overcoat can replace with C type support.
The utility model advantage compared with prior art is: when grinding machine processes unit one, with capable of regulating oil cylinder toward pressing down, stage clip just is relaxed, pulling force on fork is the pulling force of remaining small extension spring only just, this pulling force can guarantee that second workpiece enters upper roller, can easily previous workpiece be pushed away away during grinding area that bottom roller and rear bearing block form, second workpiece stably remains on grinding position, and be subjected to the pressure of small extension spring, then rise by device program control capable of regulating oil cylinder, mention screw compressing stage clip and drive the threaded adjusting inner sleeve, threaded adjusting overcoat and fork rise, under the effect of stage clip, leverage by fork is applied to second pressure on the workpiece and can progressively be increased to an accurate clamping force, and this clamping force can realize by the distance of regulating between threaded adjusting inner sleeve and the threaded adjusting overcoat; Since when clamping work pieces, there is not impulsive force, incremental, so bearing ring can not knocked distortion by upper roller, can not destroy the original circularity of bearing ring, greatly improved qualification rate and the production efficiency of product, bring good economic benefit to enterprise.
Description of drawings:
Fig. 1 is structural representation of the present utility model.
The specific embodiment:
As shown in Figure 1, a kind of spring adjustable type fixture for grinding machine is by capable of regulating oil cylinder 1, fixed support 2, small extension spring 3, fork 4, balance nut 5, mention screw 6, stage clip 7, threaded adjusting inner sleeve 8, threaded adjusting overcoat 9, Oscillating lever bearing 10, the headstock 11, rear bearing block 12, upper roller 13, bottom roller 14, round pin 15, screw thread 16, bottom roller seat 17 and form; It is characterized in that: capable of regulating oil cylinder 1 is installed on the fixed support 2, and small extension spring 3 is between fixed support 2 and fork 4, and an end is connected with fixed support 2, and the other end is connected with fork 4; Fork 4 left end positions are provided with screw thread 16, and balance nut 5 is sleeved on fork 4 left ends and is provided with on the position of screw thread 16; Stage clip 7 is installed in the threaded adjusting inner sleeve 8, and threaded adjusting inner sleeve 8 is installed in the threaded adjusting overcoat 9, mentions screw 6 and passes the rod end that stage clip 7 is fixed on capable of regulating oil cylinder 1, and threaded adjusting overcoat 9 is installed in the middle part of fork 4 by round pin 15; Fork 4 utilizes swing seat bearing 10 to be fixed on the headstock 11, and swings take Oscillating lever bearing 10 as leverage points and to realize the action of material folding and discharging; Upper roller 13 is installed in fork 4 right-hand members, and bottom, headstock right side is equipped with bottom roller seat 17, and bottom roller 14 is installed on the bottom roller seat 17, and rear bearing block 12 is screwed on the headstock 11 right flanks; Piece-holder is in the middle of upper bottom roller and rear bearing block 12; But described capable of regulating oil cylinder 1 can replace with adjusting cylinders or with servo leading screw; Described threaded adjusting inner sleeve 8 and threaded adjusting overcoat 9 can replace with C type support.
During enforcement, when grinding machine processes unit one, with capable of regulating oil cylinder 1 past pressing down, stage clip 7 just is relaxed, pulling force on fork 4 is the pulling force of remaining small extension spring 3 only just, and this pulling force can guarantee can easily previous workpiece be pushed away away when second workpiece enters the grinding area that upper roller 13, bottom roller 14 and rear bearing block 12 form; Second workpiece stably remains on grinding position, and be subjected to the pressure of small extension spring 3, then rise by device program control capable of regulating oil cylinder 1, mention screw 6 compressing stage clips 7 and drive threaded adjusting inner sleeve 8, threaded adjusting overcoat 9 and fork 4 risings, under the effect of stage clip 7, leverage by fork 4 is applied to second pressure on the workpiece and can progressively be increased to an accurate clamping force, and this clamping force can realize by the distance of regulating between threaded adjusting inner sleeve 8 and the threaded adjusting overcoat 9.
The product circularity of the utility model processing is good, and qualification rate is high, is applicable to produce in enormous quantities, has reduced enterprise's production cost, has improved production efficiency and product quality, has great promotional value.
