Description
Technical field
The present invention relates to a kind of special internal grinder bracing frame.
Background technology
Special internal grinder is when processing parts, and the general special-purpose supporting frame that adopts realizes part support, to implement the processing operations such as part internal grinding.Conventional racks comprises bracket base and two rest pads, bracket base is angle-square-shaped and is installed on grinding machine, two rest pads are at a right angle to be respectively located on bracket base, processing parts is if piston is between the end face of two rest pads, the fulcrum of rest pad end face plays the supporting role of part against the treatment of surfaces of components, the intersection point of two rest pad center lines and the central point of processing parts coincide; Each rest pad end face inlays the fulcrum that two carbide alloy make respectively, and four fulcrum end faces are arc surface through special equipment grinding.And the corresponding difference of different arc surface needs processing parts outside diameter, add four carbide alloy fulcrum arc surfaces that part in man-hour (as piston external diameter) is close on two rest pads to rotate, play pivot and the supporting role of part, because in part processing, the relative processing parts of carbide alloy fulcrum produces spin friction, easily cause fulcrum to wear and tear and the treatment of surfaces of components scuffing, have a strong impact on the quality of processing parts; The carbide alloy fulcrum simultaneously worn and torn needs to repair, in reparation, because the factors such as carbide alloy material, welding, reconditioning precision make fulcrum repair, difficulty is high, cost is high, and one secondary rest pad can only corresponding a kind of specification outside dimension part processing, lack versatility, processing various outer diameter specification part just need change different size bracing frame, so both reduce the operating efficiency of grinding machine, too increase production cost.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of special internal grinder bracing frame, this bracing frame overcomes the defect of conventional dedicated internal grinder bracing frame, its highly versatile, it is convenient that fulcrum wearability is higher, fulcrum is changed, avoid the scuffing of piece surface, ensure that the quality of processing parts, reduce production cost, improve the operating efficiency of grinding machine.
For solving the problems of the technologies described above, the special internal grinder bracing frame of the present invention comprises angle-square-shaped bracket base and two rest pads, also comprise two ceramic rods and two fishbolts, described two rest pads are at a right angle to be located at the both sides of described bracket base respectively and to be connected with bracket base by chute, described two rest pads are fastened by bolts on described bracket base, described rest pad end face is provided with arc groove and bottom arc groove, has clamping seam downwards, described rest pad clamping seam both sides are respectively equipped with counterbore and the screw of connection, described two fishbolts are each passed through the counterbore of described two rest pads and are screwed in described screw, the arc groove that described two ceramic rods embed described two rest pad end faces is respectively interior and fastening by fishbolt.
Further, on above-mentioned two rest pads ceramic rod center respectively with processing parts central point for benchmark outwards offsets 2mm.
Because the special internal grinder bracing frame of the present invention have employed technique scheme, namely this bracing frame comprises angle-square-shaped bracket base and two rest pads, also comprise two ceramic rods and two fishbolts, two rest pads are at a right angle to be located at the both sides of bracket base respectively and to be connected with bracket base by chute, two rest pads are fastened by bolts on bracket base, rest pad end face is provided with arc groove and bottom arc groove, has clamping seam downwards, rest pad clamping seam both sides are respectively equipped with counterbore and the screw of connection, two fishbolts are each passed through the counterbore of two rest pads and are screwed in screw, fastening by fishbolt in the arc groove that two ceramic rods embed two rest pad end faces respectively.This bracing frame overcomes the defect of conventional dedicated internal grinder bracing frame, increases the service life, its highly versatile, and fulcrum is changed convenient, avoids the scuffing of piece surface, ensure that the quality of processing parts, improves the operating efficiency of grinding machine, reduces production cost.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the present invention is described in further detail:
Fig. 1 is the structural representation of the special internal grinder bracing frame of the present invention;
Fig. 2 is the structural representation of rest pad in this bracing frame;
Fig. 3 is the structural representation that seat is calibrated by this bracing frame and reference center.
Detailed description of the invention
As shown in Figure 1 to Figure 3, the special internal grinder bracing frame of the present invention comprises angle-square-shaped bracket base 1 and two rest pads 2, also comprise two ceramic rods 3 and two fishbolts 4, described two rest pads 2 are at a right angle to be located at the both sides of described bracket base 1 respectively and to be connected with bracket base 1 by chute 11, described two rest pads 2 are anchored on described bracket base 1 by bolt 23, described rest pad 2 end face is provided with arc groove and bottom arc groove, has clamping seam 21 downwards, described rest pad clamping seam 21 both sides are respectively equipped with counterbore 22 and the screw 25 of connection, described two fishbolts 4 are each passed through the counterbore 22 of described two rest pads 2 and are screwed in described screw 25, the arc groove that described two ceramic rods 3 embed described two rest pad 2 end faces is respectively interior and fastening by fishbolt 4.
Further, on above-mentioned two rest pads 2 ceramic rod 3 center respectively with processing parts 5 central point for benchmark outwards offsets 2mm, namely as with processing parts 5 central point for initial point, on a rest pad, ceramic rod center offsets to positive Y direction, and on another rest pad, ceramic rod center offsets to negative X-direction.On two rest pads ceramic rod depart from processing parts center be arranged so that part put into two supporting fulcrums between center of gravity safer, play the effect of secure support processing parts.
As shown in Figure 3, the dimensions different according to processing parts, in advance this supporting base is put on reference center's calibration seat 7 and carry out calibrate, calibration seat 7 is provided with the center bar 6 arranging processing parts 5, center bar 6 is put into and needs processing parts 5, moving two rest pads 2 by adjustment screw 24 makes ceramic rod 3 contact the fastening rest pad 2 of rear bolt 23 with needing processing parts 5, and ceramic rod 3 and processing parts 5 form linear contact lay.Two removable processing operations making this bracing frame be applicable to different size part of rest pad, improve the versatility of bracing frame.
This bracing frame is by being located at the fulcrum of the ceramic rod in rest pad end face arc groove as processing parts, ceramic rod compares with conventional rigid alloy fulcrum and has the lubricity that hardness is high, wearability good and surface is good, the problem that piece surface scratches, fulcrum weares and teares because of pivoting friction generation between processing parts and fulcrum can be solved, effectively ensure that the crudy of part; To change after ceramic rod wearing and tearing quite convenient simultaneously, only need the fishbolt unscrewed on rest pad, the clamping seam of rest pad opens, ceramic rod can be shifted out in the arc groove of rest pad end face, tighten fishbolt after moving into new ceramic rod subsequently and can fix ceramic rod in arc groove, this structure overcomes the defect that conventional rigid alloy fulcrum changes difficulty, improves the efficiency that fulcrum changes operation.
This support frame structure is simple, easy to operate, and processing parts supports reliable and stable, guarantees the crudy of part, reduces production cost, improve the operating efficiency of grinding machine.
