[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field to which the present invention belongs. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0039] Embodiment 1

[0040] Referring to Figure 1 , the present invention discloses a polishing head test device, which includes:

[0041] A base 8, a grinding head assembly 2 is rotatably arranged above the base 8 through an upper main shaft 7. At the same time, the grinding head assembly 2 can adjust its position in the vertical direction. Preferably, the upper main shaft 7 is slidably arranged on the base 8 through a slide table, and the grinding head assembly 2 adjusts its position in the vertical direction through the slide table.

[0042] Specifically, the grinding head assembly 2 includes a grinding body 21 and a mounting seat 22. In this embodiment, the mounting seat 22 is a cylindrical structure, and the mounting seat 22 is rotatably arranged on the upper main shaft 7. The grinding body 21 includes a grinding block seat 211 and grinding blocks 212. Specifically, the grinding block seat 211 is an "L" - shaped structure. One end of the L - shaped grinding block seat 211 is rotatably arranged on the side of the mounting seat 22, and the other end extends into the bottom of the mounting seat 22. The grinding blocks 212 are arranged at the bottom of the grinding block seat 211.

[0043] The number of the grinding bodies 21 can be set according to the test requirements. In this embodiment, taking four grinding bodies 21 as an example, the four grinding bodies 21 are evenly distributed on the mounting seat 22.

[0044] Referring to Figure 3 , a bottom support assembly 3, the bottom support assembly 3 includes a turntable 31, and the turntable 31 is rotatably arranged below the grinding head assembly 2.

[0045] A damping assembly 1 is arranged on the turntable 31. Preferably, the damping assembly 1 is, but not limited to, a loading cylinder 11. Since loading cylinders 11 need to be arranged on both the left and right sides of the grinding block seat 211, one ends of the piston rods of the two loading cylinders 11 act on the left and right sides of the grinding block seat 211 respectively.

[0046] Specifically, as described above, the number of grinding bodies 21 is four, so the corresponding number of loading cylinders 11 is six. In this embodiment, each loading cylinder 11 corresponds to four mounting holes on the turntable 31. The four mounting holes on one side of the same grinding body 21 are symmetrically arranged with the four mounting holes on the other side with respect to the grinding block seat 211. These eight mounting holes form a hole group 9. The four grinding bodies 21 correspond to three hole groups 9. In this embodiment, the centers of the turntable 31 and the mounting seat 22 are vertically aligned, and the three hole groups 9 are centrosymmetrically arranged with respect to the center of the turntable 31. The loading cylinders 11 are fixed on the turntable 31 by bolts connected to the mounting holes. The middle position between two adjacent and opposite loading cylinders 11 is the friction test simulation position of one grinding body 21.

[0047] Specifically, to prevent direct contact between the piston rod and the grinding block seat 211 and generate sliding friction, a roller 6 is rotatably arranged at the end of the piston rod. The piston rod forms a rolling contact with the grinding block seat 211 through the roller 6.

[0048] To facilitate the layout of the air circuit of the loading cylinder 11, through holes are provided on the turntable 31. The compressed air pipeline or power line connected to the loading cylinder 11 is connected to an external air pump or battery through the through holes. It can be understood that the battery is used to drive the air pump to supply gas to the loading cylinder 11.

[0049] Specifically, according to the principle of the damping compression test, if the piston rod is required to provide damping when the grinding body 21 moves, the loading cylinder 11 is a single-acting cylinder. The principle of the single-acting cylinder is that the contraction and reset of the cylinder piston rod are due to external forces. Therefore, the gas in the compressed air pipe of the loading cylinder 11 in this embodiment is only used to push the piston rod to extend.

[0050] The test method of the polishing grinding head test device is as follows: In the initial state, the piston rod of the loading cylinder 11 is in the contracted state, and the grinding head assembly 2 is at the highest position, which is called the upper upper limit position. The mounting seat 22 rotates slowly so that the four grinding bodies 21 are respectively located directly above the center positions of the four friction test simulation positions. The grinding head assembly 2 descends from the upper upper limit position, and the four grinding block seats 211 are respectively located in the four friction test simulation positions. At this time, it is the lower upper limit position of the grinding head assembly 2.

[0051] The air pump supplies gas to the cylinder to drive the piston rod of the loading cylinder 11 to extend, and the roller 6 at the end of the piston rod abuts against the nearest side surface of the nearest grinding block seat 211.

[0052] The upper main shaft 7 rotates to drive the mounting base 22 to rotate (this can also be called revolution), with a rotational speed of 200 - 520 r / min. While the mounting base 22 is revolving, through an internal differential conversion mechanism (which is also a speed reduction mechanism, this is prior art and will not be elaborated here), the rotational speed is reduced (referred to as rotation), and the grinding block base 211 swings left and right, with a swing frequency of 30 - 80 times / min. Specifically, taking the example when the grinding block base 211 swings to the left, specifically: when the grinding block base 211 swings to the left, the piston rod of the loading cylinder 11 on the left side of the grinding block base 211 contracts under the push of the grinding block base 211. The principle of the grinding block base 211 swinging to the right is the same as that to the left and will not be elaborated here.

[0053] Further, the rotation time of the mounting base 22 is 25 - 45 min. The above time can be determined according to actual requirements. Hereinafter, an experimental time of 30 min is taken as an example;

[0054] From the above, the determination indexes for the technical performance and use stability of the grinding head assembly 2 are as follows: During the test process, observe whether there is abnormal noise in the grinding head assembly 2, and monitor the noise of the working environment of the grinding head assembly 2 every five minutes. A conventional decibel meter can be used as the noise detection instrument, and the noise decibels detected at each time point are all less than 85 dB.

[0055] After the test is completed, stop the rotation of the mounting base 22, and the air pump stops supplying air to the loading cylinder 11. At this time, perform surface temperature detection on each component of the grinding head assembly 2. Specifically, perform multi-point temperature detection on the mounting base 22, the grinding block base 211, and the grinding block 212 respectively. Preferably, select five surface temperature measurement points on each of the above temperature-measured components, and all the temperatures are less than 30°; furthermore, observe that there is no oil leakage in each component of the grinding head assembly 2.

[0056] If all the above conditions are met, it indicates that the technical performance and use stability of the grinding head assembly 2 are qualified; immediately afterwards, the piston rod of the loading cylinder 11 contracts, and the roller 6 on the loading cylinder 11 disengages from the side of the grinding block base 211. At this time, the grinding head assembly 2 moves upward, and finally the grinding body 21 disengages from the position between the two loading cylinders 11.

[0057] Embodiment 2

[0058] In this embodiment, refer to Figure 1, To ensure the synchronous rotation of the turntable 31 and the mounting base 22, a linkage assembly 13 is further included. The linkage assembly 13 includes a plug 131 and a pull sleeve 132. A plurality of plugs 131 are provided at the bottom of the mounting base 22. Correspondingly, a pull sleeve 132 for cooperating with the plug 131 is provided on the turntable 31. When the grinding head assembly 2 reaches the upper lower limit position, the pull sleeve 132 is inserted into the plug 131 to connect the turntable 31 and the mounting base 22. Therefore, it can be known that the rotation of the mounting base 22 drives the turntable 31 to rotate synchronously; Other feasible embodiments further include: the plug 131 is provided on the turntable 31, and the pull sleeve 132 is provided on the mounting base 22.

[0059] Further, as can be seen from Embodiment 1, the grinding block seat 211 needs to enter the lower friction test simulation position through the downward movement of the mounting base 22; For this purpose, to shorten the guiding time of the grinding block seat 211 to reach the position, refer to Figure 4 , the bottom support assembly 3 further includes a lifting slide seat 32 and a guide post 33.

[0060] The turntable 31 is rotatably arranged on the top of the lifting slide seat 32 through a rotating shaft 12. Specifically, at least two deep groove ball bearings 19 are provided on the lifting slide seat 32. The bottom end of the rotating shaft 12 is rotatably arranged in the two deep groove ball bearings 19, and the top end is fixedly connected to the turntable 31.

[0061] In this way, the lifting slide seat 32 can adjust its height position in the vertical direction, that is, slide in the height direction of the mounting base 22. Specifically, a plurality of guide posts 33 are provided on the base 8. In this embodiment, the number of guide posts 33 is four, and the four guide posts 33 are symmetrically distributed at the bottom of the lifting slide seat 32. Four socket holes 321 for sleeving the guide posts 33 are provided on the lifting slide seat 32, and the lifting slide seat 32 slides up and down along the guide posts 33; Preferably, to prevent direct wear between the lifting slide seat 32 and the guide posts 33, a sliding sleeve 34 is sleeved in the socket hole 321, and the lifting slide seat 32 is slidably connected to the guide posts through the sliding sleeve 34.

[0062] As can be known above, the up and down sliding of the lifting slide seat 32 requires external drive. In this embodiment, a plurality of lifting cylinders 14 are provided at the bottom of the lifting slide seat 32, and the up and down sliding of the lifting slide seat 32 is controlled by the lifting cylinders 14.

[0063] In other preferred embodiments, the lifting cylinder 14 can be a linear motor.

[0064] Furthermore, to limit the downward stroke of the lifting slide seat 32, a limit seat 15 is sleeved at the bottom of the guide post 33. It can be understood that when the bottom of the lifting slide seat 32 abuts against the top of the limit seat 15, it is the lowest position of the lifting slide seat 32, that is, the lower lower limit position of the lifting slide seat 32.

[0065] As can be seen from the above, part of the guide column 33 is exposed to the outside between the bottom of the lifting slide 32 and the bottom of the limit seat 15. In order to prevent external impurities from adhering to the guide column 33 and causing problems such as the lifting slide 32 not sliding smoothly, the present embodiment has a dust cover 16 connected to the outer cover of the guide column 33. The dust cover 16 is located below the lifting slide 32, and its top is connected to the bottom of the lifting slide 32. When the lifting slide 32 slides up and down, the dust cover 16 expands and contracts up and down, thereby better wrapping and protecting the guide column 33.

[0066] In combination with Example 1, during the process of the grinding head assembly 2 moving downward from the upper upper limit position, the turntable 31 moves upward under the action of the lifting cylinder 14 until the four grinding block seats 211 are respectively located in the four friction test simulation positions. This is the upper lower limit position of the grinding head assembly 2 and also the lower upper limit position of the turntable 31.

[0067] According to the above, it can be known that the lifting cylinder 14 directly acts on the lifting slide 32, and the lifting slide 32 is slidably connected with the guide column 33. In order to prevent the lifting cylinder 14 from directly acting on the lifting slide 32 and causing the lifting slide 32 to deform, thereby causing the lifting slide 32 and the guide column 33 to slide and get stuck, the lifting cylinder 14 is now connected to the lifting slide 32 through a slide support seat 35; preferably, in order to facilitate the connection of the lifting cylinder 14, the end of the telescopic rod of the lifting cylinder 14 of this embodiment is connected with a connecting pair, specifically, the connecting pair includes a connecting nail 17 and a socket seat 18, preferably, the connecting nail 17 is T-shaped, and a step hole is provided on the socket seat 18, one end of the T-shaped connecting nail 17 passes through the step hole and is socketed with the socket seat 18, finally, one end of the T-shaped connecting nail 17 passes through the step hole and is screwed to one end of the telescopic rod, and the socket seat 18 is connected to the slide support seat 35 by bolts.

[0068] It can be seen from the above that the purpose of setting the lifting slide 32 is: when the grinding head assembly 2 descends or rises, the lifting slide 32 drives the loading cylinder 11 to rise or descend, so that the grinding block seat 211 enters the friction test simulation position or disengages from the friction test simulation position more quickly; so when the grinding head assembly 2 descends, the lifting cylinder 14 drives the lifting slide 32 to rise, and when the grinding head assembly 2 rises, the lifting cylinder 14 drives the lifting slide 32 to descend.

[0069] Embodiment 3

[0070] The test of the grinding head assembly 2 will involve the installation of the grinding head assembly and the upper spindle 7, so refer to Figure 2 In this embodiment, a transportation system 5 is also included, and the transportation system 5 includes a guide rail 51 and a trolley 52.

[0071] Before installing the grinding head assembly 2, the guide rail 51 is spanned above the turntable 31. Preferably, the guide rail 51 can be erected through a bracket. The trolley 52 is slidably arranged on the guide rail 51, and the grinding head assembly 2 is placed on the trolley 52. Push the trolley 52 to transport the grinding head assembly 2 to directly below the upper main shaft 7. Since the upper main shaft 7 can adjust the height position in the vertical direction, after lowering the position of the upper main shaft 7 to the connection position, assemble the upper main shaft 7 and the mounting seat 22 of the grinding head assembly 2. Then lift the grinding head assembly 2 upward to disengage it from the guide rail 51. Finally, withdraw the guide rail 51 and the trolley 52 to one side of the turntable 31.

It should be noted that for those of ordinary skill in the art in this technical field, without departing from the principle of the present invention, several improvements and retouches can be made, and these improvements and retouches are also regarded as the protection scope of the present invention.
