Summary of the invention
The utility model mainly is at the high problem of the complicated cost of existing electronic expansion tool construction, provides a kind of metal tube port diameter with low cost, that make simply, conveniently use to expand instrument.
The purpose of this utility model mainly is achieved by following proposal: a kind of metal tube port diameter expands instrument, comprise fixture and expanding device, described fixture comprises last fixture block and the following fixture block that is used to clamp copper pipe, last fixture block and following fixture block are for removably connecting, and the lower surface of described upward fixture block and the upper surface of following fixture block are provided with position and the corresponding semicircle groove of size; Described expanding device comprises holder and expands bar that described expansion bar and holder flexibly connect.The semicircle groove position of last fixture block lower surface and following fixture block upper surface is corresponding with size, and the semicircle groove in both sides is combined into circular hole when fixture block splices up and down, and the diameter of circular hole can be provided with a plurality of different sizes as required.The metal tube that port diameter need be expanded is clipped in up and down between the fixture block, holder with expanding device is fixed on fixture block two ends up and down again, expand the expansion end of bar and aim at the metal tube port, utilize the expansion end that expands bar the port of metal tube to be expanded into the horn mouth of required size.Metal tube port diameter expands easy to use, the low cost of manufacture of instrument.
As preferably, described holder is the steel rectangular tube, one side of holder is provided with transverse opening, and the width sum of the width of described transverse opening and last fixture block and following fixture block is suitable, and the vertical corresponding transverse opening of described expansion bar also is threaded with holder.Holder adopts steel rectangular tube, low cost of manufacture.Transverse opening on the holder is clipped in the good both sides of fixture block up and down of splicing, expands bar and be threaded with holder, will expand the bar rotation, the expansion end of expansion bar is tight and expansion port diameter to the metal tube port inward turning that fixes.During rotation, holder can prevent the expanding device rotation, avoids expanding bar and skids.
As preferably, the described fixture block of going up is connected with following fixture block bolt.Utilize bolting when fixture block splices up and down, fastening effect is firm, and is simple to operate.
As preferably, an end of described expansion bar is a spherical crown surface.The end size that expands bar is a necessary diameter, and adopts spherical crown surface.An end that adopts spherical crown surface is as expanding end, and spherical crown surface surface slyness has good guide effect, slows down the power that is critical that produces in the reaming process.
As preferably, described semicircle groove surface is provided with anti-skidding screw thread.In the reaming process, fixture block clamps metal tube up and down, and anti-skidding screw thread can prevent that metal tube from skidding.
Therefore, metal tube port diameter expansion instrument of the present utility model possesses following advantage: 1, fixture and expanding device simple in structure, easily manufactured, cost is low; 2, fixture block clamps metal tube only to need to utilize up and down, expands bar expansion port diameter by rotation, and is easy to operate.

Illustrate: the last fixture block of 1-, fixture block under the 2-, the semicircle groove of 3-, the 4-holder, 5-expands bar, 6-transverse opening, 7-copper pipe, 8-handle, 9-fastening bolt.
The specific embodiment
Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of metal tube port diameter expands instrument, comprises fixture and expanding device.Fixture comprises last fixture block 1 and the following fixture block 2 that is used to clamp metal tube, as shown in Figure 2.Last fixture block 1 is connected with the fastening bolt 9 of following fixture block 2 by both sides.The upper surface of the lower surface of last fixture block 1 and following fixture block 2 all offers 3 positions and the corresponding semicircle groove 3 of size.When last fixture block 1 and 2 splicings of following fixture block, semicircle groove is spliced into circular hole, and the diameter of 3 circular holes that are spliced into is arranged in order from big to small, is respectively 12mm, 16mm and 19mm.The surface of semicircle groove is provided with anti-skidding screw thread, is convenient to clamp metal tube.Expanding device comprises holder 4 and expands bar 5, as shown in Figure 3, holder 4 is rectangular tubes of steel, offer a transverse opening 6 on one side of holder 4, transverse opening 6 is used to clamp the good two ends of fixture block up and down of splicing, so the width of transverse opening 6 is suitable with the width sum of fixture block up and down.Expand bar 5 and be provided with external screw thread, fixedly install an inner screw sheath on the one side relative on the holder 4, expand bar 5 and be threaded, and pass holder, guarantee expansion bar 5 vertical corresponding transverse openings 6 with inner screw sheath with transverse opening 6.An end that expands bar 5 is a spherical crown surface, and an end that adopts spherical crown surface is as expanding end, and the diameter that expands end is the diameter of required expansion, and the other end that expands bar 5 is a handle 8 vertical with expanding bar 5, and expansion bar 5 can move horizontally by rotary handle 8.
When copper pipe 7 ports that need be 16mm with diameter are expanded into 18mm, unscrew the fastening bolt 9 on fixture block 1 and the following fixture block 2, copper pipe 7 is placed on diameter is in the semicircle groove 3 of 16mm on fixture block 1 and the following fixture block 2, screw fastening bolt 9, copper pipe 7 is clamped in the circular hole that semi-circular groove 3 is combined into, and the anti-skidding screw thread on semi-circular groove 3 surfaces can prevent that copper pipe 7 from skidding.The holder 4 of expanding device is clamped the spliced both sides of fixture block up and down by the transverse opening on the holder 46, expand the expansion of bar 5 this moment and hold vertical corresponding transverse opening 6.Selecting expansion to hold diameter is the expansion bar 5 of 18mm, and with expanding the port of the expansion end aligning copper pipe 7 of bar 5, because an end of expansion bar 5 is a spherical crown surface, an end of employing spherical crown surface carries out diameter and expands, and conveniently expands the location and the guiding of bar 5.Handle 8 by on the rotation expansion bar 5 expands bar 5 translations, expands the expansion end screw-in of bar 5 and the port diameter that expands copper pipe 7.The diameter of one end of the spherical crown surface of expansion bar 5 can be selected voluntarily according to user's needs.
Compact conformation, the material of fixture and expanding device are simple, and with respect to the occasion that some counter-boring techniques frequently do not use, compact conformation, material are simple, low cost of manufacture, easily manufactured, and the user's that is more convenient for use.
