Abstract
The utility model relates to a piston rod small-end external grinding fixture. The fixture is provided with a fixed base which is arranged on the table-board of a worktable of a grinder, a mandrel with a step through hole is arranged in a through hole at the center part of the fixed base, the mandrel is connected with a driving motor by a belt transmission piece, a rotary air cylinder is sheathed at one end of the mandrel, an elastic clamping piece is arranged at the center part at the other end of the mandrel, taper sleeves which are matched with the elastic clamping piece are arranged at the two ends of the elastic clamping piece, and a propping bushing which is arranged in the mandrel is connected with the telescopic end of the rotary air cylinder by a connecting flange. The fixture can reliably ensure the small-end external grinding quality of the piston rod, and has the advantages of reasonable structural design, convenient clamping, good safety, high reliability and high production efficiency.
Description
Technical field
The utility model belongs to the damper technique field, is a kind of automobile vibration damper piston rod small end cylindricalo grinding anchor clamps that are applicable to.
Background technology
In the Grinding Technology of piston rod, normally used clamping workpiece tool, its structure is to fix a holder that has two V-type supports on the Grinder bench face, the particle size part of piston rod is clamped in the V-type groove of support as benchmark, driving one by fixed pedestal then has the axle sleeve of screw mandrel workpiece pressing to rotate, and carries out the grinding of workpiece small end cylindrical.The defective that this anchor clamps carry out grinding is: 1. because reference edge is longer apart from the grinding end, under the effect of emery wheel frictional force, easily the quality problems that dimension overproof, barring and the out-of-roundness of grinding face cause occur because of the vibration of grinding end; 2. the end face near the grinding face shoulder can be abraded by emery wheel because of the swing of grinding end, and then influences the piston rod quality of fit in when assembling, even causes scrapping of piston rod; 3. in carrying out Grinding Process, need the operative employee piston rod to be repeated the loading and unloading that clamps, unclamps with hand on V-shaped rest, in a large amount of production, not only labour intensity is big, efficient is low, and the clamping of piston and the quality of grinding also are difficult to be guaranteed reliably.
The utility model purpose
The purpose of this utility model provides a kind of crudy that can guarantee the piston rod grinding reliably, enhances productivity, and the piston rod small end cylindricalo grinding anchor clamps of convenient mounting and clamping, dependable performance.
Realize that the technical scheme that the purpose of this utility model is taked is: these anchor clamps have a fixed pedestal that is installed on the Grinder bench face, the axle of band step through-hole is housed in the through hole in fixed pedestal centre, this axle is connected with drive motors by the belt transmission part, the one end is set with rotary cylinder, the centre of the other end is provided with the elasticity clamping element, the two ends of elasticity clamping element are provided with the tapered sleeve that cooperates with it, be provided with in the axle and hold out against sleeve pipe, this holds out against sleeve pipe and is connected with the flexible end of rotary cylinder by adpting flange.
Described elasticity clamping element is the double end collet, and its two ends are cone structure.
The piston rod small end cylindricalo grinding anchor clamps of making according to such scheme can guarantee the grinding quality of piston rod small end cylindrical reliably, and have reasonable in design, convenient mounting and clamping, safe and reliable, production efficiency advantages of higher.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, piston rod small end cylindricalo grinding anchor clamps of the present utility model, comprise fixed pedestal 1, axle 2, rotary cylinder 14, elasticity clamping element 4, fixedly tapered sleeve 5, movable tapered sleeve 3, hold out against sleeve pipe 9, adpting flange 15, trim ring 13, belt pulley 12, bearing gland 11, Bearing housing 10, holding screw 16, positioning sleeve 8, spacer 7, bearing (ball) cover 6, its central shaft 2 is installed in the through hole in support body centre by bearing, and compresses with trim ring 7, bearing (ball) cover 6 in bearing gland 11, Bearing housing 10, positioning sleeve 8, the bearing respectively.The axis part of axle 2 is provided with the step through-hole that is used to install piston rod, elasticity clamping element 4 matches with movable tapered sleeve 3, and be installed in the hole of axle 2 front ends, elasticity clamping element 4 adopts double end elasticity chuck structure, its two ends are cone-shaped, and the front end of axle 2 is equipped with the fixedly tapered sleeve 5 that cooperates with elasticity clamping element 4.Rotary cylinder 14, trim ring 13 and belt pulley 12 are sleeved on the excircle position of axle 2 tail ends successively, hold out against sleeve pipe 9 and be contained in the rear portion of axle 2 through holes, and is connected with the flexible end of rotary cylinder 14 by adpting flange 15, belt pulley 12 is connected with drive motors, and the drive axle is rotated.
These anchor clamps in use, fixed pedestal 1 is installed on the work top of cylindrical grinder, adjust the relative position of the axle center of fixedly tapered sleeve front end face and axle 2 and emery wheel and be fixed, utilize charging and discharging mechanism that piston rod to be ground is sent into axle 2 and arrived Working position, moving rotary cylinder 14 of startup and drive hold out against sleeve pipe 9 and move forward, by holding out against 3 reaches of sleeve pipe 9 promotion activity tapered sleeves, at movable tapered sleeve 3 with fixedly under the acting in conjunction of tapered sleeve 5, the particle size position that elasticity clamping element 4 shrinks piston rod clamps, and guarantee the axiality of itself and axle automatically, can operation of drive motor and the emery wheel of grinding machine piston rod neck to be ground is carried out grinding.After grinding was finished, operation rotary cylinder 14 and drive held out against sleeve pipe 9 and retreat, and 4 of elasticity clamping elements unclamp naturally, can carry out next fabrication cycles, will be finished the piston rod of grinding by next workpiece in the axle 2 and release.Because this grinding is a benchmark with the retaining part of elasticity clamping element 4, the grinding neck of piston rod neither can be swung, and also axial float can not occur, thereby grinding accuracy is guaranteed reliably.
Claims (2)
1, a kind of piston rod small end cylindricalo grinding anchor clamps, it is characterized in that: these anchor clamps have a fixed pedestal that is installed on the Grinder bench face, the axle of band step through-hole is housed in the through hole in fixed pedestal centre, this axle is connected with drive motors by the belt transmission part, the one end is set with rotary cylinder, the centre of the other end is provided with the elasticity clamping element, the two ends of elasticity clamping element are provided with the tapered sleeve that cooperates with it, be provided with in the axle and hold out against sleeve pipe, this holds out against sleeve pipe and is connected with the flexible end of rotary cylinder by adpting flange.
