Description
Technical Field
The utility model relates to a testing arrangement's technical field, concretely relates to vibrations testing arrangement.
Background
The traditional test equipment for testing the vertical vibration conditions of articles such as automobile air conditioner pipes, metal hoses and the like mostly adopts a cam mechanism or a screw rod mechanism to realize the vibration function, the mechanism is easy to wear and tear under long-time use, the maintenance cost is high, on the other hand, the vibration frequency of the mechanism is not high, the detection range is narrow, and certain limitation is realized.
SUMMERY OF THE UTILITY MODEL
In view of the not enough of background art, the utility model provides a vibrations testing arrangement, the technical problem of its solution is how to effectively improve the frequency and the range of vibrations and extension fixture's life.
For solving the technical problem, the utility model provides a following technical scheme:
vibrations testing arrangement, which comprises a frame, be equipped with the linear electric motor of vertical setting in the frame, linear electric motor has the active cell, the active cell is connected with the slide, install the test mount pad on the slide, be equipped with the mounting hole that the level set up on the test mount pad, linear electric motor is last still to be fixed and is provided with the grating encoder, the detection direction of grating encoder with the axial of mounting hole is mutually perpendicular.
The rack comprises a horizontal part and a vertical part connected to the middle part of the horizontal part, the linear motor is installed on an installation surface of the vertical part, a triangular support frame is fixedly connected to the reverse side of the vertical part and the installation surface, and the bottom end of the triangular support frame is fixedly installed on the horizontal part.
The test device is characterized in that a threaded hole is formed in the sliding seat, a waist-shaped hole with the width matched with the inner diameter of the threaded hole is formed in the test mounting seat, and the test mounting seat is connected with the sliding seat through a bolt.
Compared with the prior art, the utility model beneficial effect who has is: the utility model discloses an use linear electric motor's active cell to drive the test mount pad activity from top to bottom in order to realize vibrations effect, compare cam or screw rod mechanism and can effectively avoid the friction, improve the frequency and the range of vibrations, satisfy the test needs.
Drawings
The utility model discloses there is following figure:
FIG. 1 is a schematic view of the present invention;
fig. 2 is a schematic view of fig. 1 with the carriage hidden.
Detailed Description
As shown in the figure, this kind of vibrations testing arrangement in this embodiment, including frame 1, be equipped with the linear electric motor 2 of vertical setting in frame 1, linear electric motor 2 has active cell 3, active cell 3 threaded connection has slide 4, install test mount pad 5 on the slide 4, be equipped with the mounting hole 51 of level setting on the test mount pad 5, the mounting hole 51 is used for placing articles such as metal collapsible tube or the vehicle air conditioner pipe of waiting to detect, still the fixed grating encoder 6 that is provided with on linear electric motor 2, the detection direction of grating encoder 6 with the axial of mounting hole 51 is mutually perpendicular, and grating encoder 6 can read the position of the article that awaits measuring and feed back its vibration frequency and range.
In this embodiment, the frame 1 includes a horizontal portion 11 and a vertical portion 12 connected to a middle portion of the horizontal portion 11, the linear motor 2 is mounted on a mounting surface of the vertical portion 12, a triangular support frame 13 is fixedly connected to a reverse side of the vertical portion 12 and the mounting surface, and a bottom end of the triangular support frame 13 is fixedly mounted on the horizontal portion 11. This kind of structure can play good fixed stay effect to linear electric motor 2, prevents that it from taking place to rock when transmission slide, test mount pad and the article that awaits measuring remove, whole vibrations testing arrangement, has effectively improved the stability of device to the stability of testing result has further been improved.
In the present embodiment, the test mounting base 5 is connected to the slider 4 in the following manner: the test device is characterized in that a threaded hole is formed in the sliding seat 4, a waist-shaped hole 52 with the width matched with the inner diameter of the threaded hole is formed in the test mounting seat 5, and the test mounting seat 5 is connected with the sliding seat 4 through a bolt. Because the length of waist shape hole 52 is longer than the screw hole, can adjust its position from top to bottom when installing test mount pad 5 to realize better installation effect.
To sum up, the utility model discloses an use linear electric motor 2's active cell 3 to drive test mount pad 5 activity from top to bottom in order to realize vibrations effect, because linear electric motor's characteristic itself, it can realize the non-contact motion of drive disk assembly, reduces the transmission friction, compares cam or screw mechanism and can effectively avoid the friction, and the noise is less during the operation, improves the frequency and the range of vibrations, satisfies the test needs.
