Abstract
The utility model relates to a novel drill jig for a circulating hole of an upper bearing pedestal of a shield pump. The drill jig comprises a drill jig plate and two locating pins with threads. Parallel locating holes used for accommodating the locating pins with the threads are formed in the drill jig plate. A drill bushing hole is further formed in the drill jig plate, is located between the two locating holes, and perpendicular to the two locating holes. The novel drill jig can ensure that the location degree and the size, required by drawings, of a drill hole, and improves product quality and overall beauty, is simple in structure and easy to manufacture, and all parts of the drill jig can be machined by a general lathe. When the drill jig is manufactured, the requirements for machining dimensional accuracy of the parts are not high, and only the conditions that the central line of the drill bushing and the central lines of the locating pins with the threads coincide and the interval of the two locating holes is H1 are guaranteed. Due to the fact that manual observation by means of scribing is eliminated, the machining accuracy is improved, and the production efficiency is greatly improved. In addition, the drill jig is convenient to use, and not high in the requirements for skills of operators.
Description
Technical field
The utility model relates to a kind of drill jig, and it is simple to relate in particular to a kind of Drilling Jig Structure, easy to manufacture, has saved artificial line and has observed, and improved machining accuracy, and is easy to use, to the less demanding novel canned motor pump top chock circulation port drill jig of operator's technical ability.
Background technology
Circulation port 2(such as Fig. 1 and 2 of the motor top chock 1 of canned motor pump), link together by circulation pipe and the pump housing.Yet when boring fabrication cycles hole 2, if do not guarantee the position degree (generally all requiring the center line of circulation port 2 to overlap with two hole symmetrical center line of bearing saddle bore 3) (seeing Fig. 1 and 2) in hole, the circulation pipe deflection will occur during whole pump assembling, affect the aesthetic property of the overall appearance of pump.But when boring fabrication cycles hole 2, not to be difficult to guarantee position degree by frock, therefore for the aesthetic property of the overall appearance that guarantees pump, when boring, in order to guarantee the position degree of circulation port 2, design a Special drilling jig and bore circulation port 2 and be very important.
The utility model content
For the problems referred to above, main purpose of the present utility model is to provide a kind of Drilling Jig Structure simple, easy to manufacture, having saved artificial line observes, and improved machining accuracy, and easy to use, to the less demanding novel canned motor pump top chock circulation port drill jig of operator's technical ability.
The utility model solves above-mentioned technical problem by following technical proposals: a kind of novel canned motor pump top chock circulation port drill jig, described drill jig comprises bushing plate, two threaded alignment pins, have two parallel locating holes of placing threaded alignment pin on the described bushing plate, also have the drill bushing hole on the described bushing plate, open between two locating holes in the drill bushing hole, and perpendicular to two locating holes.
In specific embodiment of the utility model: the spacing of facing mutually two bearing saddle bores on the top chock of the spacing at the center of two locating holes and needs processing equates.
In specific embodiment of the utility model: in the described bushing plate in drill bushing center line and bushing plate distance (L1) on one side and the top chock to be processed circulation port equate with the distance (L) of end face.
Positive progressive effect of the present utility model is: the novel canned motor pump top chock circulation port drill jig that the utility model provides has following advantage: bore position degree and the size that can guarantee drawing requirement with this drill jig, and product quality and overall aesthetics have been improved, Drilling Jig Structure is simple, easy to manufacture, all parts machine tools of drill jig can both be processed.When drill jig was made, each accurate to dimension was less demanding.As long as guarantee drill bushing center line and screw thread alignment pin central lines and spacing H1.Observe owing to saved artificial line, therefore can improve machining accuracy, greatly improved production efficiency.In addition, drill jig is easy to use, and is less demanding to operator's technical ability.

The specific embodiment
Provide the utility model preferred embodiment below in conjunction with accompanying drawing, to describe the technical solution of the utility model in detail.
Fig. 1 is the left view of the structural representation of top chock to be processed, and Fig. 2 is the front view of the structural representation of top chock to be processed, and as illustrated in fig. 1 and 2: the processing method that adopts at present is to rule by eye-observation before the boring, determines the position of boring.But the subjective factor of eye-observation is very large, is difficult to guarantee that the center line of circulation port 2 overlaps with the symmetrical center line in two holes of bearing saddle bore 3, and the position degree of circulation port 2 just can not guarantee like this; Because line also wastes time, production efficiency is low, and this method is difficult to meet design requirement.
Fig. 3 is the left view of the structural representation of the drilling jig tool that provides of the utility model, and Fig. 4 is the front view of the structural representation of the drilling jig tool that provides of the utility model.Shown in Fig. 3 and 4: the utility model comprises bushing plate 4, two threaded alignment pins 6, have two parallel locating holes 7 of placing threaded alignment pin on the bushing plate 4, also have drill bushing hole 5 on the bushing plate, open between two locating holes 7 in drill bushing hole 5, and perpendicular to two locating holes 7.
The spacing H1(at the center of two locating holes 7 sees Fig. 3) with the top chock 1 that needs processing on face mutually the spacing H(of two bearing saddle bores 3 with reference to figure 2) equate.
Drill bushing and bushing plate distance L 1(on one side sees Fig. 3 in the bushing plate) with top chock to be processed in circulation port equate with the distance L (see figure 5) of end face.
Fig. 5 is the left view that the drilling jig tool that provides of the utility model uses schematic diagram, and Fig. 6 is the front view that drilling jig tool that the utility model provides uses schematic diagram.As illustrated in Figures 5 and 6: the screw thread alignment pin 6 of drill jig is inserted in the bearing saddle bore 3 that top chocks 1 two-phase faces, then with nut drill jig and top chock 1 are fixed, clamping workpiece again, the drilling rod 8 of packing into just can bore circulation port 2.
The drill jig that provides with the utility model can guarantee bore position degree and the size of drawing requirement, and has improved product quality and overall aesthetics, and Drilling Jig Structure is simple, and is easy to manufacture, and all parts machine tools of drill jig can both be processed.When drill jig was made, each accurate to dimension was less demanding.As long as guarantee drill bushing center line and screw thread alignment pin central lines and spacing H1.Observe owing to saved artificial line, therefore can improve machining accuracy, greatly improved production efficiency.In addition, this drill jig is easy to use, and is less demanding to operator's technical ability.
