Description

Automotive engine test bench frock

Technical field

This utility model is specifically related to a kind of automotive engine test bench frock.

Background technology

The most mostly use public base during Engine Block Test, by cushion block regulation engine output shaft and survey The difference in height of test stand frame shaft coupling, and use pressing plate stationary engine, regulation height and shaft assignment process are numerous Trivial, it is substantially and empirically judges, the accuracy of centering cannot ensure, uses pressing plate stationary engine to hold again Easily electromotor is caused damage, therefore electromotor is arranged on testboard bay the most loaded down with trivial details arduously, start Machine output shaft and testboard spindle central centering degree of accuracy cannot ensure, directly affects Engine Block Test Accuracy.

Utility model content

The technical problems to be solved in the utility model, is to provide a kind of automotive engine test bench frock.

This utility model is achieved in that a kind of automotive engine test bench frock, is located on testboard bay, Described testboard bay has a testboard and a framework, and described testboard has a rotating shaft, on described framework Surface has two dovetail grooves, and described dovetail groove has an aperture section；Described frock includes horizontal plate, vertical Plate and two alignment pins；When in running order, the left and right sides of described horizontal plate lock onto described respectively In two dovetail grooves；Described horizontal plate is provided with two holes, location, described two holes, location and two dovetail grooves one a pair Should arrange；Every described alignment pin all inserts in a hole, location, and stretches into a corresponding dovetail groove, and this is fixed The aperture section of diameter and the described dovetail groove of position pin matches setting；It is big that the top of described vertical plate is provided with one Circular hole and four screws, the central shaft of described big hole coincides with the longitudinal axis of described rotating shaft；Described four screws Arrange with four bolt hole one_to_one corresponding of a crankcase cover of engine.

Preferably, described horizontal plate is provided with two installing hole groups, and every described location Kong Junyu mono-installing hole Group is arranged in " one " word；Every described installing hole group all includes two installing holes, and described horizontal plate is by described Four installing holes, two dovetail slot locks are paid on framework.

The utility model has the advantage of: simplify the process that electromotor is installed at testboard bay, improve work Make efficiency；Improve engine output shaft and the centering degree of accuracy of testboard rotating shaft, thus improve electromotor and survey The accuracy of examination.

Detailed description of the invention

Refer to shown in Fig. 1 and Fig. 2, a kind of automotive engine test bench frock 100, it is located at testboard bay On 200, described testboard bay 200 has testboard 1 and a framework 2, and described testboard 1 has One rotating shaft 3, described framework 2 upper surface has two dovetail grooves 21, and described dovetail groove 21 has an aperture Section 211；Described frock 100 includes horizontal plate 4, vertical plate 5 and two alignment pins 6；When being in work During state, the left and right sides of described horizontal plate 4 lock onto in described two dovetail grooves 21 respectively；Described water Flat board 4 is provided with two holes, location 41, and described two holes 41, location and two dovetail groove 21 one_to_one corresponding are arranged； Every described alignment pin 6 all inserts in a hole 41, location, and stretches into a corresponding dovetail groove 21, and this is fixed The position diameter of pin 6 and the aperture section 211 of described dovetail groove 21 match setting.On described horizontal plate 4 It is provided with two installing hole groups 42, and hole, every described location 41 is all arranged in " one " word with an installing hole group 42 Cloth；Every described installing hole group 42 all includes that two installing holes 421, described horizontal plate 4 are pacified by described four Dress hole 421, two dovetail groove 21 lock is paid on framework 2.

Referring again to Fig. 2 and Fig. 3, the top of described vertical plate 5 is provided with big hole 51 and four screws 52, the central shaft of described big hole 51 coincides with the longitudinal axis of described rotating shaft 3；Described four screws 52 Arrange with four bolt hole 7 one_to_one corresponding of electromotor 300 crankcase cover.

Referring again to Fig. 1 and Fig. 2, when applying utility model works, operating procedure is as follows:

1, first four bolts 8 are loaded in two dovetail grooves 21 of described framework 2, by the four of frock 100 Individual installing hole 421 is directed at bolt 8 and is arranged on testboard bay 200, with four nut 9 pretensions；

2, alignment pin 6 is inserted in the hole, location 41 of described horizontal plate 4, make frock 100 vertical plate 5 The center of big hole 51 and the vertical centrage alignment of testboard 1 rotating shaft 3；

3, then four bolts hole 7 of electromotor 300 crankcase cover are directed at the four of described vertical plate 5 Screw 52 is locked with four flange bolts 10, is arranged in frock 100 by electromotor 300, makes to start Machine 300 output shaft and testboard 1 rotating shaft 3 centering；

4, shaft coupling 11 is contained on electromotor 300 output shaft, by electromotor 300 together with frock 100 Advance testboard bay 200 shaft coupling (not shown), make electromotor 300 shaft coupling 11 and testboard bay 200 shaft couplings precisely coordinate；

5, finally four nuts 9 of locking can carry out the test of electromotor 300.

This utility model simplifies the process that electromotor 300 is installed at testboard 1, improves work efficiency； Improve electromotor 300 output shaft and the centering degree of accuracy of testboard 1 rotating shaft 3, thus improve electromotor The accuracy of 300 tests.
