Background

The conventional method for measuring the strength of the blank of the bonded grinding tool generally adopts a manual test method, wherein the blank is placed on a smooth plane, and then the blank is pushed at a constant speed, so that the end part of the blank leaks out of the plane until the blank breaks and the blank leaked out of the plane falls, and the method is simple and easy to implement.

It also has several drawbacks including:

1. subjective impact: the results of the manual trial are affected by subjective factors of the operator. Different people may have different strengths, speeds and patterns, which may lead to uncertainty in the test results.

The drawings are preferred embodiments of the conventional bonded abrasive tool blank strength testing device, and the utility model is further described in detail below with reference to the drawings.

The conventional bonded grinding tool blank strength testing device comprises a thrust robot and a platform 7, wherein roughness of each position on the surface of the platform 7 is consistent, and the thrust robot slides on the surface of the platform 7.

The surface roughness of the platform 7 is consistent, and the influence of the surface roughness on the blank 12 in the test process can be counteracted through calculation, so that the accuracy of the test result is further improved.

During testing, the blank 12 is placed on the platform 7, most of the blank 12 is long, when the blank is placed, the length direction is consistent with the moving direction of the blank 12, and the edges of the blank 12 can be arranged on the edge of the platform 7 in a flush manner on a vertical plane. The thrust robot pushes the blank 12 to gradually push the blank 12 to the edge of the platform 7 until the blank 12 is partially leaked to the outside of the edge and broken off under the action of gravity, and the time from the contact of the thrust robot with the blank 12 to the breaking of the blank 12 is counted.

The thrust robot has the following two arrangement forms:

first kind:

the thrust robot comprises a linear electric module and a sliding rail which is arranged in parallel with the linear electric module, the sliding rail and the linear electric module are arranged on the platform 7, and a cross beam is fixed between a sliding part of the linear electric module and a sliding part on the sliding rail. The crossbeam is arranged with sharp electronic module is perpendicular, and the crossbeam front end is fixed with push pedal 101, and sharp electronic module drives push pedal 101 and moves forward, and push pedal 101 promotes blank 12.

Second kind:

the thrust robot comprises a frame 1, driving wheels 2 are arranged at two ends of the frame 1, the driving wheels 2 are connected with a motor 4 through a speed reducing mechanism 5, and the speed reducing mechanism 5 and the motor 4 are fixedly connected with the frame 1.

The thrust robot may adopt a front drive, a rear drive or a four-drive mode, and in this embodiment, the thrust robot adopts a rear drive mode. At least two driving wheels 2 are respectively arranged on two sides of the frame 1, and a crawler belt 3 is sleeved on the driving wheels 2 on the same side. The crawler belt 3 can increase the grasping force between the thrust robot and the platform 7, avoid slipping and ensure that the thrust can act on the blank 12 unchanged.

The frame 1 top is equipped with control module 6, and control module 6 adopts prior art, including control panel and power module. The control module 6 is electrically connected with the motor 4, and controls the motor 4 to rotate in a switch or remote control mode.

The front end face of the frame 1 is provided with a push plate 101. The push plate 101 is vertically arranged, a gap is reserved between the bottom surface of the push plate 101 and the platform 7, the height of the gap is less than 5mm, the existence of the gap prevents the bottom surface of the push plate 101 from being abutted to the platform 7, friction force is increased, the height of the gap is not easy to be too large, and uneven thrust to the blank 12 is avoided.

Because it is necessary that the blank 12 breaks during testing, there should be a height difference between the underside of the platform 7 and the ground. In this embodiment, four support columns 8 are vertically arranged at the bottom of the platform 7.

The lower part of the front end surface of the platform 7 is provided with a receiving plate 9, and the broken blank 12 falls into the receiving plate 9 to be collected. In order to avoid that the blank 12 and the receiving plate 9 are scattered after collision, the receiving plate 9 is of a frame-shaped structure with an open upper end.

Because the blanks 12 of different strength are stretched by different distances from the platform 7, the receiving plate 9 is slidingly connected with the platform 7 for improved applicability.

In this embodiment, the one end that connects flitch 9 towards support column 8 is equipped with rectangle frame 10, and frame 10 cover is established on support column 8, and threaded connection has screw rod 11 on the frame 10, through rotatory screw rod 11, adjusts the extrusion force of frame 10 to support column 8, and then realizes the fixed of receiving flitch 9.

By the human eye, sometimes an inaccurate gauge of the time at which the blank 12 is pushed to fracture of the blank 12. Therefore, in order to improve the accuracy of measurement, the two sides of the moving direction of the smoke blank 12 of the platform 7 are provided with a grating used in a complete set and a timer electrically connected with the grating, and the front end of the grating extends out of the front end face of the platform 7 for a certain distance.

When the push plate 101 is abutted against the blank 12, the grating is shielded, and after the motor 4 of the thrust robot is electrified, the timer starts to count. When the blank 12 moves forward and breaks, the ray emitted by the grating is blocked before the breaking part, the breaking is the unblocking, the ray emitted by the emitter can be received by the receiver, at the moment, the timer stops timing, and the timing time on the timer is the test result.

The control program and the connection mode among the motor 4, the timer and the grating all adopt the prior art.

The embodiments of the present utility model have been described in detail with reference to the drawings, but the present utility model is not limited to the above embodiments, and various changes can be made within the knowledge of one of ordinary skill in the art without departing from the spirit of the present utility model.
