Abstract
The utility model is related to a kind of tubular type brown coal drying machine tube sheet drill jig panel assembly, the tube sheet is installed on the cutter of tubular type brown coal drying machine, is closely connect with bushing plate, and the cutter is fixedly connected with bushing plate by fixed drill bushing.Tubular type brown coal drying machine tube sheet drill jig panel assembly described in the utility model, under the premise of CNC programming boring work mesa dimensions can not be met the requirements, it can avoid manually repeating to cross using tube sheet bushing plate, reduce error rate, reduce requirement of the worker to technology, drilling efficiency is improved, while cost-effective to greatest extent.
Description
Technical field
The utility model is related to mechanical device fields, relate in particular to a kind of tubular type brown coal drying machine tube sheet bushing plate dress
It puts.
Background technology
Up to 5300mm, plate thickness 60mm, tube sheet surface is drilled with 1554 Φ 103 and justifies tubular type brown coal drying machine tube sheet diameter
Hole.When live CNC programming boring work mesa dimensions can not be met the requirements, it is necessary to cross, must first be carried out before scribing line
One bushing plate, the bushing plate are the 1/6 of entire tube sheet, on bushing plate all holes all must on CNC as requested into
Row programming drills and is compared with crossing.Single-piece integral marking is mainly taken in current this major diameter thickness drilling of tubesheet, and two
Block is with brill processing or seeks the CNC work tops progress single-piece drilling for meeting tube sheet diameter dimension.
Utility model content
The purpose of this utility model is to provide a kind of tubular type brown coal drying machine tube sheet drill jig panel assembly, to determine cutter
Position, and prevent cutter from being tilted in boring procedure, so as to ensure to be processed the positional precision in hole.
In order to solve the above technical problems, the purpose of this utility model is achieved through the following technical solutions：
A kind of tubular type brown coal drying machine tube sheet drill jig panel assembly, the tube sheet are installed on the cutter of tubular type brown coal drying machine
On, it is closely connect with bushing plate, the cutter is fixedly connected with bushing plate by fixed drill bushing.
The tube sheet has two pieces, is installed on cutter in the form of superposition connection, in concentric circles.
It drills after by bushing plate, front and rear two pieces of tube sheets are superimposed, drilled diameter is Φ 80.
There is the hole of concentric structure even compact distribution on the tube sheet.
To ensure the concentricity of two pieces of tube sheet pores, front and rear two pieces of tube sheets are superimposed and then carried out using bushing plate
Drilling, drilled diameter can arrive Φ 80.The necessary centering center of circle, drilling can be divided to two to three steps to carry out, use first during drilling
Then the drill bit centering centre bore of Φ 10 is drilled with the drill bit of Φ 30 to Φ 35 according to the track of Φ 10, finally with the brill of Φ 80
Head processing.All drilling programs must be strictly controlled, it is impossible to have bore it is askew, bore the phenomenon that inclined, need to use bolt in boring procedure
Bushing plate, tube sheet is got togather, there is phenomena such as Integrated Chip, dislocation in gap between preventing plate.Drill bit must assure that vertical and chip removal is suitable
Freely, normally, scene preferably ensures that the radial drill for having two bench drill bore dias up to more than 100mm works at the same time, and such stress would not
It concentrates somewhither, tube sheet is also not easy to deform.
The beneficial effects of the utility model are：
Tubular type brown coal drying machine tube sheet drill jig panel assembly described in the utility model programs boring work table top ruler in CNC
It is very little can not meet the requirements under the premise of, using tube sheet bushing plate can avoid manually repeat cross, reduce error rate, reduce worker to skill
The requirement of art improves drilling efficiency, while cost-effective to greatest extent.
Description of the drawings
Fig. 1 is the structure diagram of tubular type brown coal drying machine tube sheet drill jig panel assembly；
Fig. 2 is the structure diagram of tubular type brown coal drying machine；
Fig. 3 is tube plate structure schematic diagram；
Wherein, 1- tube sheets；2- cutters；3- bushing plates；4- fixes drill bushing.
Specific embodiment
The utility model is described in further detail below in conjunction with attached drawing：The present embodiment is with the utility model skill
Implemented under premised on art scheme, give detailed embodiment, but the scope of protection of the utility model be not limited to it is following
Embodiment.
As depicted in figs. 1 and 2, a kind of tubular type brown coal drying machine tube sheet drill jig panel assembly, it is brown that the tube sheet 1 is installed on tubular type
It on the cutter 2 of coal drier, is closely connect with bushing plate 3, the cutter 2 is fixedly connected with bushing plate 3 by fixed drill bushing 4.
The tube sheet 1 has two pieces, is installed on cutter 2 in the form of superposition connection, in concentric circles.
It drills after by bushing plate 3, front and rear two pieces of tube sheets 1 are superimposed, drilled diameter is Φ 80.
As shown in figure 3, there is the hole of concentric structure even compact distribution on the tube sheet 1.
To ensure the concentricity of two pieces of 1 pores of tube sheet, using bushing plate 3 then front and rear two pieces of tube sheets 1 are superimposed
It drills, drilled diameter can arrive Φ 80.The necessary centering center of circle, drilling can be divided to two to three steps to carry out during drilling, first
The drill bit centering centre bore of Φ 10 is first used, is then drilled with the drill bit of Φ 30 to Φ 35 according to the track of Φ 10, finally with Φ 80
Drill bit processing.All drilling programs must be strictly controlled, it is impossible to have bore it is askew, bore the phenomenon that inclined, need to use in boring procedure
Bolt is bushing plate 3, tube sheet 1 is got togather, and phenomena such as Integrated Chip, dislocation occurs in gap between preventing plate.Drill bit must assure that it is vertical and
Chip removal is smooth, normal, and scene preferably ensures that the radial drill for having two bench drill bore dias up to more than 100mm works at the same time, such stress
It would not concentrate somewhither, tube sheet 1 is also not easy to deform.
The preferable specific embodiment of the above, only the utility model, these specific embodiments are all based on this
Different realization methods under utility model general idea, and the scope of protection of the utility model is not limited thereto, it is any ripe
It knows in the technical scope that those skilled in the art disclose in the utility model, the change or replacement that can be readily occurred in, all
It should cover and be within the protection scope of the utility model.
