Description
Technical field
The invention belongs to bearing shell processing technique field.
Background technology
Bearing shell (Engine bearings) bearing shell is sliding bearing and the tactile part that is coupling, and unusual light, the high-abrasive materials such as general bronze, antifriction alloy are made.The bearing shell of new casting is through after the assay was approved, and need alloy unnecessary for upper and lower watt of contact surface (i.e. end face) shoot off and grind, upper and lower watt is carried out being combined to form bearing shell entirety by the instrument that re-uses, and machines.
Existing when the contact surface process of bearing shell, be all adopt the manually hand-held type scraping knife that then uses to carry out digging unnecessary alloy, then on this watt or lower tiling end face is contacted with grinding head grind.The shortcoming of this mode is: artificial hand-held time easily there is the problem such as shakiness, hand shaking, and bearing shell end face is very narrow, the easily outer ring of scuffing bearing shell of mistake or the surface of inner ring when using scraper.
Summary of the invention
The invention is intended to provide a kind of and clamp firm, to prevent from scratching bearing shell surface bearing shell clamping device.
Bearing shell clamping device in this programme, comprises frame and pedestal, and pedestal upper surface has the deep-slotted chip breaker holding bearing shell, and frame is vertically provided with by briquetting above deep-slotted chip breaker, and the lower surface of briquetting is arc pressure surface; The axle center of briquetting has axis hole, shaft hole inner wall has one section of vertical gathering sill, and the cylinder output shaft lower end that frame is vertically arranged is with guide block, and cylinder output shaft inserts in the axis hole of briquetting and its guide block mates with gathering sill; The both sides of briquetting are respectively arranged with left scraping block and right scraping block, left scraping block by left connecting rod and cylinder output shaft hinged, right scraping block by right connecting rod and cylinder output shaft hinged.
Beneficial effect of the present invention is as follows: Shang watt or lower watt be placed in deep-slotted chip breaker, briquetting under the drive of cylinder output shaft its arc pressure surface by upper watt or lower watt of compression, meanwhile, cylinder output shaft continues mobile in axis hole, the left and right scraping block hinged with cylinder output shaft is moved, thus by upper watt or lower watt of end face on unnecessary alloy exclude.Structure of the present invention is simple, and owing to being affixed with bearing shell cambered surface, clamping is very firm, and can not damage the surface of bearing shell during the scraping of scraping block.
Further, the bottom land of gathering sill is higher than at the bottom of the hole of axis hole, and because cylinder output shaft axle body is provided with guide block, design makes the lower end of cylinder output shaft contact completely with bottom axis hole completely like this, increases its stroke.
Further, the notch of gathering sill is provided with cover plate, and this cover plate and briquetting are bolted, and prevents cylinder output shaft from exiting axis hole.
Further, the axle body of cylinder output shaft is welded with contiguous block, the upper end of left connecting rod and right connecting rod and this contiguous block are by hinge, and because cylinder output shaft is cylindrical, time hinged, installation difficulty is comparatively large, reduces hinged installation difficulty by being welded to connect block.
Accompanying drawing explanation
Fig. 1 is the structural representation of bearing shell clamp embodiment of the present invention.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
Reference numeral in Figure of description 1 comprises: pedestal 1, deep-slotted chip breaker 2, briquetting 3, arc pressure surface 4, axis hole 5, gathering sill 6, cylinder output shaft 7, guide block 8, contiguous block 9, left connecting rod 10, right connecting rod 11, left scraping block 12, right scraping block 13, cover plate 14, bearing shell 15.
Embodiment is substantially as shown in Figure 1: bearing shell clamping device, and comprise frame, pedestal 1 and briquetting 3, this pedestal upper surface has deep-slotted chip breaker 2, bearing shell 15 upper watt or lower watt of outer wall can to fit this deep-slotted chip breaker cell wall.
Briquetting is positioned at above deep-slotted chip breaker, the lower surface of briquetting be with upper watt or the lower watt of inwall arc pressure surface 4 of fitting, the axle center of briquetting has axis hole 5, and the inwall of this axis hole has one section of vertical gathering sill 6, the bottom land of this gathering sill is higher than at the bottom of the hole of axis hole.The notch of gathering sill uses cover plate 14 to add bolt and seals.The guide block 8 coordinated with gathering sill is welded in the lower end of the cylinder output shaft 7 that frame is vertically arranged.The installation process of cylinder output shaft is first insert in the axis hole of briquetting by cylinder output shaft, and guide block inserts in gathering sill, then covers the cover plate at gathering sill notch place, after bolt tightening cover plate, can complete the connection of cylinder output shaft and briquetting.
The contiguous block 9 of the side's of being welded with bodily form on the axle body of cylinder output shaft, this contiguous block there are left connecting rod 10 and right connecting rod 11 by hinge, left scraping block 12 on the left of this left connecting rod and lower end and briquetting upper surface is by hinge, and the right scraping block 13 on the right side of the lower end of right connecting rod and briquetting upper surface passes through hinge.
The course of work of the present embodiment is as follows: when upper watt or lower watt be placed in the deep-slotted chip breaker of pedestal, briquetting moves down along with stretching out of cylinder output shaft, know the arc pressure surface of briquetting with upper watt or the inner surface of lower watt contact, the upper surface of briquetting and upper watt or the end face of lower watt, now cylinder output shaft continues in the axis hole of briquetting lower mobile, thus promote left scraping block and right scraping block moves respectively to left side and right side, thus by upper watt or lower watt of end face on unnecessary alloy exclude.
Above-described is only embodiments of the invention, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect the practicality of effect of the invention process and invention.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
