Description

Vertical connecting rod of drill pump clamping and positioning device

Technical field

The utility model belongs to machining equipment technical field, is exclusively used in connecting rod of drill pump processing quick-clamping location, relates to a kind of vertical connecting rod of drill pump clamping and positioning device.

Background technology

Connecting rod is the vital part in oil drilling pump, is low-alloy high-strength steel casting, belongs to Pear-Shaped prolate shape shape, and part body is larger.Connecting rod need to be processed through hole and the hole end surface of the through hole of stub end, little head end, and the necessary size conforms drawing requirement that guarantees two pitch-rows, due to the particularity of part body, it is inconvenient that microcephaly's end adds the clamping location in man-hour for a long time, non-cutting time is very long, is the key factor that affects product working (machining) efficiency.

Existing processing mode is, product is first rule and determined working position size, on vertical lathe, stub end through hole and end face are carried out to roughing adds man-hour reference data as microcephaly hole, then on boring machine, process contour leveling and adjusting connecting rod level by horizontal connecting rod placement and according to level, then after holding through hole processing line with boring spindle centering microcephaly, connecting rod clamping is fixed.The processing method of this little head end, fail effectively to utilize the working position of stub end as the clamping benchmark of rear operation, the universal fixturing of use has determined that clamping, location, the centering operation of connecting rod is loaded down with trivial details, takies non-cutting time greatly, be not suitable for batch production, and human factor impact is large.

Utility model content

The purpose of this utility model is to provide a kind of vertical connecting rod of drill pump clamping and positioning device, has solved the location and the clamping centering operation that in prior art, exist loaded down with trivial details, takies large problem non-cutting time.

The technical scheme that the utility model adopts is, a kind of vertical connecting rod of drill pump clamping and positioning device, comprise vertical pedestal, on vertical pedestal front, along continuous straight runs is provided with centering machine on one side, for being set with the stub end of connecting rod, be provided with vertical V-type clamping device at along continuous straight runs another side, for clamping the little head end of connecting rod.

Vertical connecting rod of drill pump clamping and positioning device of the present utility model, its feature is also:

Centering machine comprises three locating dowels, and these three locating dowels are even circumferential setting, and one of them is arranged on below of circumference, and three locating dowel correspondences of centering machine are arranged on three alignment pin installing holes of vertical pedestal.

Centering machine is provided with a set of eccentric stiffener in a locating dowel of below.

In three locating dowels of centering machine, be all set with a contour annulus, these three contour annulus height dimensions are identical.

The beneficial effects of the utility model are, utilize through hole that big end end processed and end face as clamping benchmark, adopt three points centering, contour annulus as quick positioning means; Adopt eccentric wheel, V-type clamping device as Quick-clamped means, thereby realize quick location and the clamping that small end of connecting rod end adds man-hour.Accurate positioning, easy for installation, fixing reliable, artifical influence factor is little, is suitable for batch production.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is elaborated.

With reference to Fig. 1, Fig. 2, the structure of the vertical connecting rod of drill pump clamping and positioning device of the utility model is, comprise vertical pedestal 1, on vertical pedestal 1 front, along continuous straight runs is provided with centering machine 2 on one side, for being set with the stub end of connecting rod 6, on vertical pedestal 1, along continuous straight runs another side is provided with vertical V-type clamping device 5, for clamping the little head end of connecting rod 6; In three locating dowels of centering machine 2, be all set with a contour annulus 4, centering machine 2 is provided with a set of eccentric stiffener 3 in a locating dowel of below.

Centering machine 2 comprises three locating dowels, three are even circumferential setting, one of them is arranged on below of circumference, three locating dowel correspondences of centering machine 2 are arranged on 1 three alignment pin installing holes of vertical pedestal, these three locating dowels have adopted 3 principles of determining a circle, according to big end end clear size of opening and the center of circle, on vertical pedestal 1, have three corresponding alignment pin installing holes, as quick-clamping positioning datum.

Eccentric stiffener 3 is arranged on centering machine 2 in a locating dowel of below.Eccentric stiffener 3 comprises with the eccentric wheel of offset and eccentric wheel locking piece thereof, adopts eccentric adjusting and self-locking structure, utilizes its offset to realize the self-locking that connecting rod is removed stage makeup and costume after gap and compression.

Contour annulus 4 comprises three, and these three contour annulus 4 height dimensions are identical, is set on three locating dowel circumference of centering machine 2, guarantees that linkage plane is vertical with centerline hole.

As Fig. 3, the vertical bent plate (back side) of vertical pedestal 1 adopts the rear support mode of right angled triangle, has handling convenient, easy operating, and little advantage takes up room.

As Fig. 4, the opening size capable of regulating of V-type clamping device 5, utilize upper and lower V-block to small end of connecting rod end cylindrical nature centering, by the self-locking screw mandrel (screw mandrel that in Fig. 1, right side is connected with two V-blocks, helical angle has auto-lock function) adjustment clamping small end of connecting rod end, connecting rod integral rotates take major part stomidium center as the center of circle and (drives the little head end of product to adjust up and down because right-hand member screw mandrel moves up and down, right-hand member is to hang in three locating dowels, it is naturally just around its center rotating), realize microcephaly's stomidium center and overlap with machining center, guarantee connecting rod installation accuracy.

The course of work of the utility model device is:

Step 1, connecting rod are transported in face of vertical pedestal 1 with vertical hanging, major part stomidium is hung in three locating dowels of centering machine 2, stub end hole end surface and three groups of contour annulus 4 are adjacent to (see figure 2), and connecting rod, by the tenesmus of deadweight nature, has guaranteed that connecting rod center overlaps naturally with the centre of location.

The bottom V-block of step 2, adjustment V-type clamping device 5, makes small end of connecting rod stomidium center overlap with machining center, then top V-block is pressed down to connecting rod, thereby realization is firm to the clamping of small end of connecting rod end, guarantees to add the stable of connecting rod in man-hour.

After step 3, the adjustment of small end of connecting rod end clamp, big end end through hole is carried out to locked clamping with eccentric stiffener 3.The quick-clamping location of so far having realized connecting rod, can start to process microcephaly's stomidium.

Device of the present utility model adopts vertical clamping mode, method take the big end stomidium that processes as positioning datum application three points centering, adjust the machining center of small end of connecting rod stomidium in conjunction with V-type clamp mechanism, method is simple, structure is unique, easy to use, location is reliable, has effectively shortened the clamping non-cutting time before processing, significantly enhances productivity.
