Abstract

The utility model relates to a drilling and positioning device for a limiting tooth of a transmission system of a concrete mixer truck and belongs to a drilling device. The drilling and positioning device is characterized by mainly consisting of a standard hole pattern plate, a central positioning bolt, a nut, a gasket, a left puller nut, a left puller screw, a right puller nut and a right puller screw, wherein the standard hole pattern plate is disc-shaped; standard holes are arranged at the radial central line on left and right sides of the standard hole pattern plate according to the aperture and pitch designed for the limiting tooth; the central positioning bolt is fixedly installed in the centre of the standard hole pattern plate; the gasket is sleeved on the central positioning bolt and the nut is screwed on the central positioning bolt; the left and right puller nuts which are vertically arranged are respectively welded on the periphery at both sides of the standard hole pattern plate; and the left and right puller screws with arc heads are correspondingly screwed in the left and right puller nuts. The drilling and positioning device is used for drilling the limiting tooth on a small drilling machine according to the standard hole, and is convenient and reliable.

Description

The boring positioner of the spacing gear piece of concrete mixer truck transmission system
Technical field
The utility model belongs to drilling equipment, especially relates to a kind of drilling equipment of spacing gear piece.
Background technology
The transmission system of trucd mixer is the key position of complete vehicle quality; Spacing gear piece is again a vitals of controlling the hydraulic motor rotating speed of adorning on engine and the trucd mixer; This component controls trucd mixer cylindrical shell forward uniform rotation and reverse uniform rotation, therefore very high to the requirement of this parts boring and location; In general, if this spacing gear piece adopts artificial line location and boring, not only time-consuming; And boring, location can not reach designing requirement, can not fine assurance pitch-row with each hole on same center line, often make product quality uneven; Greatly reduce employee's efficiency, influence assembling of trucd mixer car load and performance, bring the uncertainty on many safety for the continuous back work of product; Prolong the production cycle of product, restricted the large-scale production of product.
Summary of the invention
The purpose of the utility model is the boring positioner that proposes the spacing gear piece of a kind of concrete mixer truck transmission system, and is not only rational in infrastructure, easy to use, and can improve the quality of products and operating efficiency, reduces labor intensity of operating personnel.
The purpose of the utility model is that realization is like this: the boring positioner of the spacing gear piece of a kind of concrete mixer truck transmission system; The boring positioner that it is characterized in that the spacing gear piece of this concrete mixer truck transmission system is held out against by datum hole template, centralized positioning bolt, nut, packing ring, a left side mainly that nut, left fastening screw, the right side hold out against nut, right fastening screw is formed; This datum hole template is disc; About it to radial centre lines on offer each datum hole by spacing gear piece set aperture and pitch-row; In the center fixation of this datum hole template (being welded) centralized positioning bolt is installed simultaneously; Suit packing ring and spinning nut on the heart bolt hereinto; Hold out against nut with the right side holds out against nut on the left side of putting on vertical that is welded respectively on the periphery of the left and right sides of this datum hole template, and make this left and right line of centres that holds out against nut and datum hole template about to radial centre lines be arranged in same vertical plane, distinguish the left and right fastening screw of corresponding spinning in the nut left and right holding out against; The medial end of this left and right fastening screw is the circular arc head, and the outboard end Duan Shangjun of fastening screw holes and is equipped with handle in the left and right sides.
During use, the centre bore on the spacing gear piece to be holed is sleeved on the centralized positioning bolt of this device, and this spacing gear piece and left and right fastening screw is positioned on the sustained height with packing ring; Twist left and right fastening screw then respectively; In the arc groove of the centre of corresponding roof pressure on spacing gear piece left and right sides circumference, (centre bore on this spacing gear piece shapes in preceding working procedure with each arc groove) tightened left and right fastening screw; And tighten the nut on the centralized positioning bolt; To clamp this boring positioner upset of spacing gear piece at last, on small drilling machine, spacing gear piece holed according to datum hole, convenient reliable again.
The boring positioner of the spacing gear piece of concrete mixer truck transmission system that the utility model proposed, rational in infrastructure, use reliably, improved the quality and the operating efficiency of spacing gear piece and trucd mixer car load, reduced labor intensity of operating personnel.
Combine accompanying drawing and embodiment that the boring positioner of the spacing gear piece of concrete mixer truck transmission system that the utility model proposed is described further at present.
Description of drawings
Fig. 1 is the main cross-sectional schematic of the boring positioner of the spacing gear piece of concrete mixer truck transmission system that proposes of the utility model when using.
Fig. 2 is the schematic top plan view of the boring positioner of the spacing gear piece of concrete mixer truck transmission system that proposes of the utility model when using.
Among Fig. 1, Fig. 2: 1, datum hole template 2, spacing gear piece 3, packing ring 4, centralized positioning bolt 5, nut 6, right fastening screw 7, the right side hold out against nut 8, left fastening screw 9, a left side and hold out against nut.
The specific embodiment
From Fig. 1, Fig. 2, can find out: the boring positioner of the spacing gear piece of a kind of concrete mixer truck transmission system; The boring positioner that it is characterized in that the spacing gear piece of this concrete mixer truck transmission system is held out against by datum hole template 1, centralized positioning bolt 4, nut 5, packing ring 3, a left side mainly that nut 9, left fastening screw 8, the right side hold out against nut 7, right fastening screw 6 is formed; This datum hole template 1 is disc; About it to radial centre lines on the aperture and the pitch-row that are designed by spacing gear piece 2 offer each datum hole; In the center fixation of this datum hole template 1 (being welded) centralized positioning bolt 4 is installed simultaneously; Suit packing ring 3 and spinning nut 5 on the heart bolt 4 hereinto; A left side of on being welded vertically on the periphery of the left and right sides of this datum hole template 1 respectively, putting holds out against nut 9 and holds out against nut 7 with the right side; And make this left and right line of centres that holds out against nut 9,7 and datum hole template 1 about to radial centre lines be arranged in same vertical plane; At the left and right left and right fastening screw 8,6 of corresponding spinning respectively that holds out against in the nut 9,7, the medial end of this left and right fastening screw 8,6 is the circular arc head, in the outboard end Duan Shangjun of left and right fastening screw 8,6 boring and be equipped with handle.
During use; Centre bore on the spacing gear piece 2 to be holed is sleeved on the centralized positioning bolt 4 of this device; And this spacing gear piece 2 is positioned on the sustained height with left and right fastening screw 8,6 with packing ring 3, twist left and right fastening screw 8,6 then respectively, in the arc groove of the centre of corresponding roof pressure on spacing gear piece 2 left and right sides circumference; (centre bore on this spacing gear piece 2 shapes in preceding working procedure with each arc groove); Tighten left and right fastening screw 8,6, and tighten the nut 5 on the centralized positioning bolt 4, will clamp this boring positioner upset of spacing gear piece 2 at last; On small drilling machine, spacing gear piece 2 is holed according to datum hole, convenient reliable again.
