Abstract

The utility model discloses a tooling for processing a horizontal extension slot at the end part of a slotted hole at the middle part of a pillar. The tooling comprises a base, a vertical plate vertically arranged on the top surface of the base and position-limiting devices symmetrically arranged on two side surfaces of the vertical plate, wherein the position-limiting device arranged on one side surface of the vertical plate comprises a first position-limiting column vertically fixed at the middle part of the side surface of the vertical plate, a second position-limiting column and a compaction mechanism. The tooling has the advantages as follows: the pillar position-limiting devices are arranged on the two sides of the vertical plate on the top surface of a baseplate, the position-limiting devices are configured and arranged according to the shape of the pillar, a circular hole at the middle part of the pillar is sheathed on the first position-limiting column, the second position-limiting column and the first position-limiting column, as well as a vertical screw rod and a pressure plate, which are arranged on the top surface of the vertical plate, are matched for realizing the positioning of the pillar, and the clamping is simple; furthermore, two pillars can be clamped once, and the production efficiency is effectively improved.

Description

A kind of pillar intermediate channel bore ends level prolongs the groove processing tool

Technical field

The utility model has related to the secondary process frock of the pillar that uses on a kind of Train brake beam, particularly a kind of pillar intermediate channel bore ends level prolong the groove processing tool.

Background technology

The Train brake beam is the vitals in the Train brake system, it is directly connected to train vibration influence safety, and brake beam strut is the core component of brake beam, pillar mainly bears the relative load between brake beam girder and the auxiliary girder in the brake beam work progress, its loading status is complicated, for the brakes inefficacy that prevents to lose efficacy and bring because of pillar, production and processing to pillar has proposed higher requirement, pillar one end that is installed on the brake beam is processed into arc groove, this arc groove auxiliary girder middle part circular arc portion direct and brake beam coincide, its other end is provided with bayonet socket, is fixed on brake beam girder middle part after bayonet socket and clip fasten; In order to strengthen the antitorque ability of pillar and to alleviate pillar weight, process a long slot bore and axis normal at the pillar middle part simultaneously in the circular hole of long slot bore hole wall; Long slot bore one end also is processed with level and prolongs groove, and level prolongs groove and is located on the middle facial planes of two pillars vertical with long slot bore; Since in the pillar facial planes and an end bayonet socket vertical plane not on same plane, out-of-shape, so the location is difficult in the pillar process, process though can directly pillar be positioned on the workbench of vertical knee-type milling machine at present by cushion block, but owing to can only process one at every turn, and positioning time is longer, directly influences its working (machining) efficiency.

The utility model content

Technical problem to be solved in the utility model provides a kind of pillar intermediate channel bore ends level and prolongs the groove processing tool, can effectively improve pillar intermediate channel bore ends level and prolong the groove working (machining) efficiency.

For solving the problems of the technologies described above, the technical scheme that the utility model adopted is: a kind of pillar intermediate channel bore ends level prolongs the groove processing tool, comprises pedestal, is vertical at the riser on the base top surface and is symmetrically set in stopping means on the riser two sides; The described stopping means of being located on riser one side comprises first limited post, second limited post and the hold-down mechanism that is vertically fixed on middle part, riser side; The diameter of described first limited post equals the internal diameter of pillar middle part circular hole; Described second limited post is located at the lower right corner, riser side, the distance of the axis in the vertical direction of the axis of second limited post and first limited post equals the axis of pillar middle part circular hole and the radius that the distance on the vertical direction between the middle facial planes in parallel adds second limited post, and the distance that the horizontal range between the axis of the axis of second limited post and first limited post equals the middle facial planes right-hand member of round hole axial and pillar in the middle part of the pillar subtracts the radius of second limited post; Described hold-down mechanism comprises the vertical screw rod that is fixed on riser end face right-hand member and is sleeved on pressing plate on the vertical screw rod, also comprises the nut with the vertical supporting setting of screw rod.

Adopt the beneficial effect that technique scheme produced to be: the riser both sides of being located on the substrate top surface are equipped with one group of pillar stopping means, and stopping means is according to the supporting setting of shape of pillar, pillar middle part circle hole sleeve is contained on first limited post, second limited post and first limited post and be located at vertical screw rod on the riser end face and the location of the supporting realization pillar of pressing plate, clamp easy, and once clamp two pillars, effectively enhance productivity.

The specific embodiment

A kind of pillar intermediate channel bore ends level as shown in Figures 1 to 4 prolongs the groove processing tool, it is characterized in that: comprise pedestal 1, be vertical at the riser 2 on pedestal 1 end face and be symmetrically set in stopping means on riser 2 two sides; The described stopping means of being located on riser 2 one sides comprises first limited post 3, second limited post 4 and the hold-down mechanism that is vertically fixed on middle part, riser side; The diameter of described first limited post 3 equals the internal diameter of pillar middle part circular hole; Described second limited post 4 is located at the lower right corner, riser 2 side, the distance of the axis in the vertical direction of the axis of second limited post 4 and first limited post 3 equals the axis of middle part circular hole 8-1 of pillar 8 as shown in Figure 5 and the radius that the distance on the vertical direction between the middle facial planes 8-2 in parallel adds second limited post 4, and the distance that the horizontal range between the axis of the axis of second limited post 4 and first limited post 3 equals the middle facial planes right-hand member of the middle part circular hole 8-1 axis of pillar 8 and pillar subtracts the radius of second limited post 4; Described hold-down mechanism comprises the vertical screw rod 7 that is fixed on riser 2 end face right-hand members and is sleeved on pressing plate 5 on the vertical screw rod 7, also comprises the nut 6 with vertical screw rod 7 supporting settings.

In concrete application process, at first frock is fixedly mounted on the workbench of vertical knee-type milling machine, then the pillar symmetry is positioned on the stopping means of being located on the riser two sides, the long slot bore at pillar middle part vertically is provided with, compress pillar with pressing plate, vertical screw rod and nut cooperation, start vertical knee-type milling machine milling intermediate channel hole horizontal at last and prolong groove, the level that one side is finished in milling prolongs groove turnover support later on, repeat above-mentioned location and operating procedure, finish the processing of the level prolongation groove of other one side, enhance productivity greatly.
