A robot component testing device

Abstract

The present invention provides a robot component testing device, which relates to the technical field of testing devices and includes a dynamic balance testing machine, an installation part, a cleaning part, and a washing part. First, the roller needs to be clamped with the limit rod, then pushed to the left, and then the locking seat is threadedly connected to the rotating shaft, so that when installing the roller, the steel ring on the roller can be prevented from hitting the thread on the rotating shaft by the shielding of the limit rod, thereby avoiding poor connection between the locking seat and the rotating shaft. This solves the problem that when performing dynamic balance testing on the roller, a dynamic balance tester needs to be used, and the staff needs to install the roller on the rotating shaft of the dynamic balance tester. During the installation process, the steel ring of the roller is likely to collide with the thread on the rotating shaft, thereby affecting the normal use of the device. At the same time, if there are impurities on the roller during testing, it will affect the testing accuracy.

[0040] The following further describes the implementation manners of the present invention in detail with reference to the drawings and embodiments.

[0041] Embodiment: Please refer to Figures 1 to 8 :

[0042] The present invention provides a robot component testing device, including: a dynamic balance testing machine 1, an installation part 2, a cleaning part 4 and a cleaning part 5;

[0043] The dynamic balance testing machine 1 is placed on the ground; a protective seat 102 is fixed to the right end face of the dynamic balance testing machine 1;

[0044] The installation part 2 is composed of a rotating shaft 201, a first retaining ring 202, a mounting seat 203, a limiting rod 204, a second retaining ring 205, an elastic member 206, a locking seat 207, a contact block 208 and a protrusion 209. The rotating shaft 201 is rotatably connected to the dynamic balance testing machine 1, and the rotating shaft 201 is connected to the rotating shaft of the driving motor in the dynamic balance testing machine 1;

[0045] The cleaning part 4 is composed of a sliding rod 401, a protective plate 402, a cleaning brush 403, a spring rod 404 and a handle 405; there are four sliding rods 401 in total, and the four sliding rods 401 are all welded to the top end face of the protective seat 102;

[0046] The cleaning part 5 is installed on the cleaning part 4;

[0047] The cleaning part 5 is composed of a water storage box 501, a water outlet pipe 502 and an extrusion switch 503.

[0048] Among them, two first retaining rings 202 are welded on the rotating shaft 201; a protrusion 209 is welded to both the top end face and the bottom end face of the outer wall of the rotating shaft 201. The two protrusions 209 are both rectangular block structures, and the protrusions 209 are located between the two first retaining rings 202;

[0049] A mounting base 203 is slidably connected to the rotating shaft 201 and the protrusion 209. At this time, the mounting base 203 cannot rotate axially and is located between two first retaining rings 202. Six limiting rods 204 are annularly arrayed on the right end face of the mounting base 203, and the six limiting rods 204 are inserted into the fixing holes on the roller 3. At this time, axial limitation of the roller 3 can be achieved, facilitating subsequent detection of the roller 3.

[0050] Among them, a resilient member 206 is sleeved on the rotating shaft 201, and the resilient member 206 is a helical spring structure;

[0051] The right end of the resilient member 206 is in elastic contact with the left end face of the mounting base 203, and the left end of the resilient member 206 is in elastic contact with the right end face of the left first retaining ring 202;

[0052] A locking seat 207 is threadedly connected to the rotating shaft 201. When the locking seat 207 is tightened, the resilient member 206 is in an elastically compressed state. During detection, the elastic pushing of the resilient member 206 can achieve the abutment of the roller 3 against the locking seat 207, thereby reducing the probability of loosening of the locking seat 207.

[0053] Among them, a contact block 208 is rotatably connected to the left end face of the locking seat 207. The contact block 208 is an annular structure, and the left end face of the contact block 208 is in contact with the right end face of the steel ring on the roller 3. When the locking seat 207 is tightened, the rotation between the locking seat 207 and the contact block 208 can replace the friction between the contact block 208 and the steel ring, thereby avoiding wear of the steel ring.

[0054] Among them, the six limiting rods 204 are all cylindrical rod structures, and a second retaining ring 205 is welded to each of the six limiting rods 204. The right end faces of the six second retaining rings 205 are respectively abutted against the left end face of the steel ring on the roller 3, thereby avoiding shaking of the roller 3 during the detection process.

[0055] Among them, the right end faces of the six limiting rods 204 are all polished. After being polished, the right ends of the six limiting rods 204 are all arc-shaped structures, which can improve the smoothness when the limiting rods 204 are inserted into the fixing holes on the steel ring during use.

[0056] Among them, when the resilient member 206 elastically extends, the right end face of the mounting base 203 is in elastic contact with the left end face of the right first retaining ring 202. At this time, the right end of the limiting rod 204 is located on the right side of the right end of the rotating shaft 201. Then, when installing the roller 3, first, the roller 3 needs to be clamped with the limiting rod 204, then pushed to the left, and then the locking seat 207 is threadedly connected to the rotating shaft 201. Then, when installing the roller 3, the steel ring on the roller 3 can be prevented from hitting the thread on the rotating shaft 201 by the shielding of the limiting rod 204, thereby avoiding poor connection between the locking seat 207 and the rotating shaft 201.

[0057] Among them, a protective plate 402 is slidably connected to four sliding rods 401. The protective plate 402 is in the shape of a rectangular plate and is located above the roller 3. During the detection process, the protective plate 402 can block the debris thrown off by the roller 3.

[0058] Among them, a spring rod 404 is installed on the top end surface of the protective seat 102, and the upper end of the spring rod 404 is fixed to the bottom end surface of the protective plate 402;

[0059] A cleaning brush 403 is installed on the bottom end surface of the protective plate 402, and the cleaning brush 403 is located 5 cm above the roller 3;

[0060] A handle 405 is welded to the front end surface of the protective plate 402. When the handle 405 is pulled down by 5 cm, the cleaning brush 403 contacts the roller 3. At this time, the roller 3 can be cleaned by the cleaning brush 403, thereby improving the detection accuracy.

[0061] Among them, a water storage box 501 is installed on the top end surface of the protective plate 402. A water outlet pipe 502 is connected to the water storage box 501, and the lower end of the water outlet pipe 502 is located 5 cm above the roller 3. During use, when the water outlet pipe 502 discharges water, the roller 3 can be cleaned.

[0062] Among them, a squeeze switch 503 is installed on the water outlet pipe 502. When the squeeze switch 503 is squeezed, the water outlet pipe 502 is in a water discharge state;

[0063] An auxiliary rod 101 is installed on the dynamic balance tester 1. The auxiliary rod 101 is in the shape of an L-shaped bent rod, and the auxiliary rod 101 is aligned with the squeeze switch 503;

[0064] When the protective plate 402 moves downward by 5 cm, the auxiliary rod 101 contacts the squeeze switch 503. At this time, the water outlet pipe 502 can discharge water, thereby realizing the cleaning of the roller 3.

[0065] The specific usage method and function of this embodiment:

[0066] In use, first install the roller 3 on the limit rod 204, then push the roller 3 to the left, and then thread the locking seat 207 onto the rotating shaft 201 and tighten it. At this time, since two first retaining rings 202 are welded to the rotating shaft 201; a protrusion 209 is welded to both the top end face and the bottom end face of the outer wall of the rotating shaft 201. Both protrusions 209 are rectangular block structures, and the protrusions 209 are located between the two first retaining rings 202; an installation seat 203 is slidably connected to the rotating shaft 201 and the protrusions 209. At this time, the installation seat 203 cannot rotate axially, and the installation seat 203 is located between the two first retaining rings 202; six limit rods 204 are annularly arrayed on the right end face of the installation seat 203. All six limit rods 204 are inserted into the fixing holes on the roller 3. At this time, axial limitation of the roller 3 can be achieved, facilitating subsequent detection of the roller 3; also, since a resilient member 206 is sleeved on the rotating shaft 201, and the resilient member 206 is a helical spring structure; the right end of the resilient member 206 is elastically in contact with the left end face of the installation seat 203, and the left end of the resilient member 206 is elastically in contact with the right end face of the left first retaining ring 202; a locking seat 207 is threadedly connected to the rotating shaft 201. When the locking seat 207 is tightened, the resilient member 206 is in an elastically compressed state. During detection, the roller 3 can be pressed against the locking seat 207 by the elastic push of the resilient member 206, thereby reducing the probability of loosening of the locking seat 207; also, since a contact block 208 is rotatably connected to the left end face of the locking seat 207, and the contact block 208 is an annular structure, the left end face of the contact block 208 is in contact with the right end face of the steel ring on the roller 3. When tightening the locking seat 207, the rotation between the locking seat 207 and the contact block 208 can replace the friction between the contact block 208 and the steel ring. At this time, wear of the steel ring can be avoided; also, since all six limit rods 204 are cylindrical rod structures, a second retaining ring 205 is welded to each limit rod 204. The right end faces of the six second retaining rings 205 are respectively pressed against the left end face of the steel ring on the roller 3. At this time, the roller 3 can be prevented from shaking during the detection process; also, since the right end faces of all six limit rods 204 are polished, and after polishing, the right ends of all six limit rods 204 are arc-shaped structures, the smoothness of the insertion of the limit rods 204 into the fixing holes on the steel ring can be improved during use; when the resilient member 206 elastically extends, the right end face of the installation seat 203 is elastically in contact with the left end face of the right first retaining ring 202. At this time, the right end of the limit rod 204 is located to the right of the right end of the rotating shaft 201. Then, when installing the roller 3, first, the roller 3 needs to be engaged with the limit rod 204, then pushed to the left, and then the locking seat 207 is threadedly connected to the rotating shaft 201. Then, when installing the roller 3, the steel ring on the roller 3 can be prevented from hitting the thread on the rotating shaft 201 by the shielding of the limit rod 204, thereby preventing poor connection between the locking seat 207 and the rotating shaft 201;

[0067] Then, start the dynamic balance testing machine 1. At this time, hold the handle 405 and pull it downward. Since a spring rod 404 is installed on the top surface of the protective seat 102, the upper end of the spring rod 404 is fixed to the bottom surface of the protective plate 402. A cleaning brush 403 is installed on the bottom surface of the protective plate 402, and the cleaning brush 403 is located 5 cm above the roller 3. A handle 405 is welded to the front surface of the protective plate 402. When the handle 405 is pulled downward by 5 cm, the cleaning brush 403 contacts the roller 3. At this time, the roller 3 can be cleaned by the cleaning brush 403, thus improving the detection accuracy. Also, since a water storage box 501 is installed on the top surface of the protective plate 402, a water outlet pipe 502 is connected to the water storage box 501, and the lower end of the water outlet pipe 502 is located 5 cm above the roller 3. During use, when the water outlet pipe 502 discharges water, the roller 3 can be cleaned. Also, since a squeeze switch 503 is installed on the water outlet pipe 502, when the squeeze switch 503 is squeezed, the water outlet pipe 502 is in a water discharge state. An auxiliary rod 101 is installed on the dynamic balance testing machine 1. The auxiliary rod 101 is an L-shaped bent rod structure, and the auxiliary rod 101 is aligned with the position of the squeeze switch 503. When the protective plate 402 moves downward by 5 cm, the auxiliary rod 101 contacts the squeeze switch 503. At this time, the water outlet pipe 502 can discharge water, thus realizing the cleaning of the roller 3.

[0068] During use, since a protective plate 402 is slidably connected to four sliding rods 401, the protective plate 402 is a rectangular plate structure, and the protective plate 402 is located above the roller 3. During the detection process, the protective plate 402 can block the debris flying off the roller 3.
