[0052] The embodiments of the present application will be further described in detail below in combination with the drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0053] The following will be combined Figs. 1-3 to describe the selection test device for polishing consumables of the present application.

[0054] As Figs. 1-3 shown, the selection test device for polishing consumables provided by the embodiments of the present application comprises a base 1, a test piece placing table 2, a polishing tool mounting frame 3 and a pose adjusting mechanism.

[0055] Specifically, the base 1 is used for supporting, and the test piece placement table 2 and the pose adjustment mechanism are arranged on the base 1. The test piece placement table 2 is used for placing the test piece, and the polishing tool mounting rack 3 is used for mounting the polishing tool 4, wherein the polishing tool 4 is mounted with the polishing consumable 5 to be tested.

[0056] The polishing tool mounting rack 3 can be arranged in the form of a clamping sleeve as shown in the drawings. Fig. 1

[0057] It should be noted that the polishing tool 4 can be an angle grinder or a straight grinder, and the polishing consumable 5 can be a grinding head, a grinding sheet, a grinding wheel sheet, etc. When performing selection testing, the polishing tool 4 is selected according to the type of the polishing consumable 5 to be tested. When testing a plurality of polishing consumables 5, for each polishing consumable 5 of the same type, the same polishing tool 4 is used for testing, so as to avoid the influence of the polishing tool 4 on the selection testing.

[0058] The pose adjustment mechanism is arranged between the polishing tool mounting rack 3 and the base 1, and the polishing tool mounting rack 3 is mounted on the base 1 through the pose adjustment mechanism. The pose adjustment mechanism includes a position adjustment assembly and an angle adjustment assembly. The position adjustment assembly is used for adjusting the relative position of the polishing tool mounting rack 3 and the test piece placement table 2, and the angle adjustment assembly is used for adjusting the relative angle of the polishing tool mounting rack 3 and the test piece placement table 2. Through the pose adjustment mechanism, the position and the angle of the polishing tool mounting rack 3 relative to the test piece placement table 2 can be adjusted, so that the position and the polishing angle of the polishing consumable 5 to be tested are adjusted.

[0059] Different polishing consumables 5 correspond to different standard polishing angles, and the same polishing consumable 5 with different sizes corresponds to different standard polishing angles. After the polishing tool 4 mounted with the polishing consumable 5 to be tested is mounted on the polishing tool mounting rack 3, the angle of the polishing tool mounting rack 3 needs to be adjusted according to the standard polishing angle corresponding to the polishing consumable 5 to be tested, so that the polishing consumable 5 to be tested is polished in a standard state.

[0060] ​In this way, when the selection test of the polishing consumable 5 needs to be performed, the test piece and the polishing tool 4 provided with the polishing consumable 5 to be tested are respectively installed on the polishing tool mounting rack 3 and the test piece placing table 2. The angle of the polishing tool mounting rack 3 relative to the test piece placing table 2 is adjusted according to the standard polishing angle of the polishing consumable 5 to be tested, so that the actual polishing angle of the polishing consumable 5 to be tested is consistent with the standard polishing angle of the polishing consumable 5 to be tested, and the selection test of the polishing consumable 5 to be tested is performed in the standard state. Then, the position of the polishing tool mounting rack 3 is adjusted according to the position of the test piece, and the polishing tool 4 is started to perform polishing. During the polishing process, the position and angle of the polishing tool mounting rack 3 remain fixed, and accordingly the position and polishing angle of the polishing consumable 5 to be tested remain unchanged, thereby avoiding the influence of the change of the polishing parameters on the selection test, greatly improving the accuracy of the selection test, and being beneficial to improving the product quality.

[0061] Furthermore, the selection test device for the polishing consumable provided in the embodiment of the utility model has the position and posture adjusting mechanism, can adjust the position and polishing angle of the polishing consumable 5 to be tested, can make various polishing consumables 5 to be tested perform the selection test in the standard state corresponding to the polishing consumable 5 to be tested, and can further improve the accuracy of the selection test.

[0062] In addition, the selection test device for the polishing consumable provided in the embodiment of the utility model is used to replace the manual test, reduces the manual participation, and improves the test safety.

[0063] In the embodiment, the position adjusting assembly includes a base 6, a sliding block 7, a driving member and a first locking member.

[0064] The base 6 is fixed relative to the base 1, the sliding block 7 is slidingly connected with the base 6, and the sliding direction of the sliding block 7 relative to the base 6 is parallel to the distribution direction of the base 6 and the test piece placing table 2. When the sliding block 7 slides relative to the base 6, the sliding block 7 can approach or move away from the test piece placing table 2.

[0065] The driving member is arranged between the sliding block 7 and the base 6, and the driving member can drive the sliding block 7 to slide relative to the base 6.

[0066] The first locking member can selectively limit the sliding of the sliding block 7 relative to the base 6. When the position of the sliding block 7 on the base 6 needs to be adjusted, the first locking member is switched to the unlocked state, the limitation of the first locking member on the sliding block 7 is released, and thus the driving member can drive the sliding block 7 to slide relative to the base 6. After the position of the sliding block 7 is adjusted, the first locking member is switched to the locked state, the sliding of the sliding block 7 relative to the base 6 is limited by the first locking member, so that the position of the sliding block 7 is stable, and thus the position stability of the polishing consumable 5 to be tested is improved.

[0067] The base 6 is provided with length scale marks, facilitating determination of the relative position of the sliding block 7 and the base 6.

[0068] In the embodiment of the utility model, the driving member at least includes a rotating part 8 and a moving part, and the driving member further includes one of a power input part 9 and a driving part.

[0069] That is, in some embodiments, the driving member includes the rotating part 8, the moving part, and the power input part 9, and in other embodiments, the driving member includes the rotating part 8, the moving part, and the driving part.

[0070] The rotating part 8 is rotationally connected to the base 6, the moving part is in transmission connection with the rotating part 8, and the sliding block 7 is connected to the moving part.

[0071] Specifically, the transmission connection between the moving part and the rotating part 8 can be a screw nut transmission connection or a gear and rack transmission connection. The transmission connection mode of the moving part and the rotating part 8 can only be able to convert the rotating action of the rotating part 8 into the moving action of the moving part, and is not limited.

[0072] The power input part 9 or the driving part is used to be connected to the rotating part 8 and to provide torque to the rotating part 8 to drive the rotating part 8 to rotate relative to the base 6.

[0073] Specifically, the power input part 9 can be a rotating handle, and the rotating handle is manually rotated to apply torque to the rotating part 8. The driving part can be an electric motor, and the electric motor applies torque to the rotating part 8.

[0074] In this embodiment, the first locking member includes a locking hole and a first locking part 10, the locking hole is arranged on the rotating part 8, and the first locking part 10 is movably connected to the base 6, so that the first locking part 10 can selectively enter and exit the locking hole.

[0075] Specifically, the first locking part 10 is threadedly connected to the base 6, the axis of the locking hole is arranged along the radial direction of the rotating part 8, the axis of the first locking part 10 coincides with the axis of the locking hole, the first locking part 10 is moved relative to the base 6 by screwing the first locking part 10 to enter and exit the locking hole. When the first locking part 10 enters the locking hole, the first locking part 10 and the side wall of the locking hole interact to limit the rotation of the rotating part 8 relative to the base 6, corresponding to the locking state of the first locking member. When it is necessary to make the sliding block 7 slide relative to the base 6, the first locking part 10 can be screwed out of the locking hole, corresponding to the unlocking state of the first locking member.

[0076] In the embodiment of the utility model, the angle adjusting assembly includes a cantilever 11, a second locking member, and a third locking member.

[0077] The first end of the cantilever 11 is rotationally connected with the sliding block 7, and the polishing tool mounting rack 3 is rotationally connected with the second end of the cantilever 11. The rotation axis of the cantilever 11 relative to the sliding block 7 and the rotation axis of the polishing tool mounting rack 3 relative to the cantilever 11 are parallel, and both are parallel to the bearing surface of the test piece placing table 2.

[0078] By rotating the cantilever 11 relative to the sliding block 7, or rotating the polishing tool mounting rack 3 relative to the cantilever 11, or both, the angle of the polishing tool mounting rack 3 can be adjusted, so that the polishing angle of the polishing tool 4 and the polishing consumable 5 can be adjusted.

[0079] By combining the rotation of the cantilever 11 relative to the sliding block 7 and the rotation of the polishing tool mounting rack 3 relative to the cantilever 11, the angle of the polishing tool 4 and the position and polishing angle of the polishing consumable 5 can be accurately adjusted.

[0080] The second locking member can selectively limit the rotation of the cantilever 11 relative to the sliding block 7. When the angle of the cantilever 11 relative to the sliding block 7 needs to be adjusted, the second locking member is switched to the unlocked state to release the restriction of the second locking member on the cantilever 11, so that the cantilever 11 can be rotated relative to the sliding block 7. After adjusting the angle of the cantilever 11 relative to the sliding block 7, the second locking member is switched to the locked state to limit the rotation of the cantilever 11 relative to the sliding block 7 by the second locking member, so as to ensure the stability of the angle of the cantilever 11, which is conducive to improving the stability of the angle of the polishing tool 4 and the polishing angle of the polishing consumable 5.

[0081] The third locking member can selectively limit the rotation of the polishing tool mounting rack 3 relative to the cantilever 11. When the angle of the polishing tool mounting rack 3 relative to the cantilever 11 needs to be adjusted, the third locking member is switched to the unlocked state to release the restriction of the third locking member on the polishing tool mounting rack 3, so that the polishing tool mounting rack 3 can be rotated relative to the cantilever 11. After adjusting the angle of the polishing tool mounting rack 3 relative to the cantilever 11, the third locking member is switched to the locked state to limit the rotation of the polishing tool mounting rack 3 relative to the cantilever 11 by the third locking member, so as to ensure the stability of the angle of the polishing tool mounting rack 3, which is conducive to improving the stability of the angle of the polishing tool 4 and the polishing angle of the polishing consumable 5.

[0082] In this embodiment, the second locking member includes a locking plate 12 and a second locking piece 14.

[0083] The locking plate 12 is fixedly arranged on the sliding block 7, and the locking plate 12 is perpendicular to the bearing surface of the test piece placing table 2 and located on one side of the cantilever 11. The first end of the cantilever 11 can be rotationally connected with the sliding block 7, or rotationally connected with the locking plate 12.

[0084] The locking plate 12 is provided with an arc-shaped slot 13, and the center of the arc of the arc-shaped slot 13 is located on the rotation axis of the cantilever 11 relative to the sliding block 7.

[0085] The first end of the second locking member 14 penetrates the arc-shaped slot 13 and is threadedly connected with the cantilever 11, and the second end of the second locking member 14 is provided with a first abutting portion which can abut against the side of the locking plate 12 away from the cantilever 11.

[0086] By screwing the second locking member 14, the first abutting portion can be made to approach or move away from the locking plate 12. When the first abutting portion abuts against the locking plate 12, the rotation of the cantilever 11 relative to the locking plate 12 and the sliding block 7 can be limited by the friction between the first abutting portion and the locking plate 12, corresponding to the locking state of the second locking member. When it is needed to rotate the cantilever 11 relative to the locking plate 12 and the sliding block 7, the second locking member 14 is screwed to have a gap between the first abutting portion and the locking plate 12, corresponding to the unlocking state of the second locking member, at this time, the second locking member 14 rotates relative to the locking plate 12 and the sliding block 7 synchronously with the cantilever 11.

[0087] The first angle scale mark is arranged on the locking plate 12, facilitating the determination of the angle of the cantilever 11.

[0088] In the embodiment, the third locking member includes a third locking member 15.

[0089] The first end of the third locking member 15 penetrates the second end of the cantilever 11 and is threadedly connected with the polishing tool mounting rack 3. The second end of the third locking member 15 is provided with a second abutting portion which can abut against the side of the cantilever 11 away from the polishing tool mounting rack 3.

[0090] By screwing the third locking member 15, the second abutting portion can be made to approach or move away from the cantilever 11. When the second abutting portion abuts against the cantilever 11, the rotation of the polishing tool mounting rack 3 relative to the cantilever 11 can be limited by the friction between the second abutting portion and the cantilever 11 and the friction between the cantilever 11 and the polishing tool mounting rack 3, corresponding to the locking state of the third locking member. When it is needed to rotate the polishing tool mounting rack 3 relative to the cantilever 11, the third locking member 15 is screwed to have a gap between the second abutting portion and the cantilever 11 or a gap between the cantilever 11 and the polishing tool mounting rack 3, corresponding to the unlocking state of the third locking member.

[0091] The second angle scale mark is arranged on the second end of the cantilever 11, facilitating the determination of the angle of the polishing tool mounting rack 3 relative to the cantilever 11.

[0092] In the embodiment of the utility model, the type selection testing device of polishing consumables further includes a counterweight mechanism, which is detachably connected with the polishing tool mounting rack 3. When the counterweight mechanism is installed on the polishing tool mounting rack 3, the counterweight mechanism can generate a downward force on the polishing tool 4. At this time, the second locking member can be switched to the unlocked state, and the counterweight mechanism can increase the polishing intensity of the polishing tool 4.

[0093] The counterweight mechanism includes a counterweight mounting rack and counterweight blocks 16. At least two counterweight blocks 16 are provided, and any one of the counterweight blocks 16 can be installed on the counterweight mounting rack. The number of counterweight blocks 16 provided on the counterweight mounting rack can be adjusted. By adjusting the number of counterweight blocks 16 on the counterweight mounting rack, the polishing intensity of the polishing tool 4 can be adjusted.

[0094] In the embodiment, the counterweight mounting rack includes a connecting seat 17 and a fastener.

[0095] The connecting seat 17 is connected with the polishing tool mounting rack 3. Specifically, the connecting seat 17 and the polishing tool mounting rack 3 can be connected together by using bolts.

[0096] The connecting seat 17 is provided with a connecting column, and the counterweight block 16 is provided with a through hole through which the connecting column penetrates. After the counterweight block 16 is arranged outside the connecting column, the fastener is connected with the connecting column to restrict the counterweight block 16 from being pulled out of the connecting column by using the fastener.

[0097] Specifically, the fastener is threadedly connected with the connecting column.

[0098] To improve the stability of the counterweight block 16 on the counterweight mounting rack, two parallel connecting columns can be provided, and each connecting column corresponds to at least one fastener. At this time, the counterweight mounting rack further includes a gasket. After the counterweight block 16 is arranged outside the two connecting columns, the gasket is arranged outside the two connecting columns, and then the fastener is connected with the connecting column.

[0099] In the embodiment of the utility model, the test piece placing table 2 includes a placing table body and a driving assembly.

[0100] The placing table body is used to support the test piece. The placing table body can rotate about the axis relative to the base 1, and the driving assembly is used to drive the placing table body to rotate about the axis relative to the base 1.

[0101] In this way, during the type selection testing process, the placing table body can drive the test piece to rotate, so that the polishing consumable 5 can polish different positions of the test piece, avoiding excessive polishing of the same position of the test piece by the polishing consumable 5, avoiding changes in the polishing angle and polishing intensity caused by excessive polishing to form pits on the test piece, and further improving the accuracy of the type selection testing.

[0102] It should be noted that the fixing member needs to be arranged on the placing table body, and after the test piece is placed on the placing table body, the test piece is fixed by the fixing member to rotate synchronously with the placing table body, so as to avoid the position displacement of the test piece or the problem that the test piece slides off the placing table body.

[0103] In the embodiment of the utility model, the selection and testing device for polishing consumables further comprises a tray 18 and a protective cover 19.

[0104] The tray 18 is arranged on the base 1, and the pose adjusting mechanism and the test piece placing table 2 are both arranged inside the tray 18, so that the tray 18 can hold the grinding dust generated in the polishing process and facilitate cleaning.

[0105] The protective cover 19 can be arranged outside the test piece placing table 2, the polishing tool mounting rack 3 and the pose adjusting mechanism, and the protective cover 19 is detachably connected with the tray 18. During the polishing process, the protective cover 19 is connected with the tray 18 to prevent the grinding dust from splashing and improve the test safety.
