Abstract
The invention provides a device for preventing sand from entering holes, comprising a fixed side-pressing plate, a movable side-pressing plate, a bottom cover plate, a movable side-pressing plate positioning pin for positioning the movable side-pressing plate, a fixed side-pressing plate positioning pin for positioning the fixed side-pressing plate, a hinge, a press rod, attachment bolts and fastening nuts. The fixed side-pressing plate is linked with the press rod by the hinge. The bottom cover plate and the press rod are fastened together by the attachment bolts. The bottom cover plate can rotate along with the rotation of the press rod. The device of the invention has the following technical effects: as cavities are formed between the parts of the device, the sand ejected at high speed can be isolated out of the rolling element channels, the fixed support bolt holes, the fixed bolt holes on the sealing covers and the internal surfaces of the slider cavities, thus preventing the surface, which does not require sand blast, of the slider of the linear rolling guide from sand blast and reducing the subsequent cleaning procedure and the production and processing cost.
Description
Technical field
The present invention relates to a kind of device for preventing sand from entering holes, be used for the blasting treatment of the slide block finished surface of linear rolling guide, belong to field of machining.
Background technology
Linear rolling guide is as a kind of precision of Digit Control Machine Tool, straight-line guidance parts, and, positioning accuracy little because of its resistance of motion and repetitive positioning accuracy height, good reliability and versatility be good to be able to extensive use.
In order to improve the surface anticorrosive ability of linear rolling guide, can carry out blasting treatment to the shoe surface of linear rolling guide usually, so not only can remove the oxide layer of shoe surface, and can play the effect of anti-corrosion.As shown in Figure 1; carry out in the blasting treatment process of the test at slide block 10 linear rolling guide; many sand grains can stick in the rolling element passage 11 that machined and bracket fixing bolt hole 13, the seal cover fixed bolt hole 12; can increase the difficulty of next procedure cleaning and polishing processing like this, also influence product quality.In sand grains sticks to the rolling element passage, because cleaning is not thorough, just as increased abrasive body in raceway, has quickened the wearing and tearing of rolling element and raceway, shorten dramatically service life, easily causes the positioning accuracy of linear rolling guide and repetitive positioning accuracy forfeiture rapid; In sand grains enters support and seal cover fixed bolt hole, when clearing up, usually cause screw tap to fracture in bolt hole with screw tap, not only increase the cleaning difficulty, and increased the processing cost of subsequent handling.Other does not need the surface of sandblast, owing to sprayed sand, so that surface roughness increases, has influenced product assembly quality on the contrary.
Summary of the invention
The present invention provides a kind of device for preventing sand from entering holes in order to address the above problem, and the cleaning process and the production and processing cost in road, back reduced by sandblast in the surface that does not need sandblast that can prevent the linear rolling guide slide block.
Device for preventing sand from entering holes of the present invention, comprise fixation side pressing plate, active side pressing plate, bottom plate, be used for the geocoded activity side guide active side pressing plate alignment pin, be used for fixation side pressing plate alignment pin, hinge, depression bar, attachment bolt and the clamp nut of positioning and fixing side guide, said fixation side pressing plate and depression bar link by hinge; Said bottom plate and depression bar tighten together with attachment bolt, and bottom plate can rotate with the rotation of depression bar.
Preferably, this device comprises two attachment bolts, all is used for fastening bottom plate and depression bar.
Preferably, said depression bar is the screw thread depression bar, and said clamp nut is a wing nut.
Device for preventing sand from entering holes of the present invention, has following technique effect: owing to form cavity between the various piece of device for preventing sand from entering holes, the sand grains that penetrates at a high speed can be completely cut off outside rolling element passage, fixed support bolt hole, seal cover fixed bolt hole and slider type inner cavity surface, the cleaning process and the production and processing cost in back road reduced by sandblast in the surface that does not need sandblast that can prevent the linear rolling guide slide block.
Description of drawings
Fig. 1 is not for adopting the structural representation of device for preventing sand from entering holes linear rolling guide slide block in the prior art;
Fig. 2 is the structural representation of device for preventing sand from entering holes of the present invention;
Fig. 3 is the left view of Fig. 2;
Wherein, 1 is the fixation side pressing plate, 2 fixation side pressing plate alignment pins, 3 is the active side pressing plate, and 4 is active side pressing plate alignment pin, and 5 is bottom plate, 6 is hinge, 7 is attachment bolt, and 8 is the screw thread depression bar, and 9 is wing nut, 10 is slide block, 11 is the rolling element passage, and 12 is the seal cover fixed bolt hole, and 13 is the bracket fixing bolt hole.
The specific embodiment
As Fig. 2, shown in Figure 3, device for preventing sand from entering holes of the present invention, comprise fixation side pressing plate 1, active side pressing plate 3, bottom plate 5, be used for the active side pressing plate alignment pin 4 of geocoded activity side guide 3, the fixation side pressing plate alignment pin 2 that is used for positioning and fixing side guide 1, hinge 6, screw thread depression bar 8, two attachment bolts 7 and wing nuts 9, fixation side pressing plate 1 links by hinge 6 with screw thread depression bar 8; Bottom plate 5 and screw thread depression bar 8 tighten together with two attachment bolts 7, and bottom plate 5 can rotate with the rotation of screw thread depression bar 7.
Device for preventing sand from entering holes of the present invention is performed such work, fixation side pressing plate 1 is positioned at a side of slide block by fixation side pressing plate alignment pin 2; Active side pressing plate 3 is positioned the another side of slide block by active side pressing plate alignment pin 4, threaded depression bar 8 is embedded in the medial launder of active side pressing plate 3, fastening with wing nut 9, realize forming between fixation side pressing plate 1, active side pressing plate 3, bottom plate 5 and the slide block chamber of a sealing, thereby the sand grains that will penetrate at a high speed completely cuts off outside rolling element passage, fixed support bolt hole, seal cover fixed bolt hole and slider type inner cavity surface.Do not need sand blasted surface by sandblast thereby stoped.
