Description

Technical Field

[0001] The utility model relates to the field of grinding and polishing mechanical equipment, and particularly relates to a polishing device for the bottom and the mouth of a heat preservation cup. Background Art

[0002] At present, in the production of heat preservation cups, the external polishing of the heat preservation cups is mostly completed manually. The environment in the polishing workshop is very harsh - there is a lot of dust and noise. It is easy to cause occupational diseases such as pneumoconiosis for the operators. There is an urgent need for professionals to design special equipment to replace manual operations.

[0003] The heat preservation cup mainly includes a cup body, and a cup bottom and a cup mouth located at both ends of the cup body. The cup mouth is usually made by a pressing process. The polishing work of the heat preservation cup mainly includes cup body polishing, cup bottom polishing, cup mouth polishing, etc. To solve the problem of heat preservation cup polishing, in the prior art, a heat preservation cup polishing machine, a single-station polishing machine and a production line can realize the external polishing of the cup body of the heat preservation cup. However, for the existing heat preservation cup bottom polishing equipment, during the polishing work, the heat preservation cup can only rotate around the rotation axis of the heat preservation cup, and due to the connection of the air pipe, it can only rotate a little more than one circle around the rotation axis, and the air pipe is often wound in, with great limitations. The technical problems existing in the prior art are as follows: First, it is impossible to complete the polishing work at the connection between the cup bottom and the cup body cup mouth with a relatively large right-angle turning arc. Second, the existing bottom polishing equipment can only form rotating polishing patterns. For some heat preservation cups with process requirements such as transverse bottom polishing, the existing bottom polishing equipment cannot complete it. Third, in addition to polishing the body and the bottom of the heat preservation cup, some cups with special shapes need to be polished at the pressed mouth. There is currently no corresponding equipment to complete this process, which affects the full automation of the polishing production line. Fourth, it is impossible to realize the function of rotating and polishing multiple circles around the rotation axis, with great limitations, affecting the reliability and continuity of the cup bottom and cup mouth polishing.

[0111] The following will describe in detail the specific implementation manners of the present utility model with reference to the accompanying drawings.

[0112] The present utility model provides a polishing device for the bottom and mouth of a thermos cup, which is applied to polish the bottom or mouth of a thermos cup. Refer to Figure 1 Combined with Figure 4 , the thermos cup 10 has a cup body 11, a cup bottom 12 and a cup mouth 13. The cup bottom 12 and the cup mouth 13 are located at both ends of the cup body 11, and the cup body 11 is a rotating body with a thermos cup rotation axis 14. Refer to Figure 1As shown in the figure, the polishing equipment for the bottom and mouth of the heat-insulating cup provided by the utility model includes: a bed body 19, a tool assembly, a compound motion module, and a cup body rotation assembly. The tool assembly includes a polishing wheel 21 and a polishing motor 22. The compound motion module includes: a first-direction reciprocating movement assembly 30, a second-direction reciprocating movement assembly 40, and a third-direction rotation assembly 50, which drives the heat-insulating cup to perform a compound motion of reciprocating movement in the first direction X, reciprocating movement in the second direction Y, and rotational movement in the third direction Z (which can be defined as C-axis movement). The cup body rotation assembly 60 is mounted on the compound motion module, and the cup body rotation assembly 60 can clamp the body 11 of the heat-insulating cup. When polishing, the polishing motor 22 drives the polishing wheel 21 to rotate around the first-direction X axis, the compound motion module drives the cup body rotation assembly to make the bottom 12 or the mouth 13 of the heat-insulating cup abut against the polishing wheel 21, and the cup body rotation assembly drives the heat-insulating cup to rotate around the heat-insulating cup rotation axis 14.

[0113] Refer to Figure 1 As shown in the figure, the first direction X, the second direction Y, and the third direction Z are perpendicular to each other, forming a fixed reference three-dimensional coordinate system; the heat-insulating cup rotation axis 14 is the rotation axis that moves in a compound motion together with the heat-insulating cup.

[0114] Refer to Figure 1 As shown in the figure and refer to Figure 2 As shown in the figure and refer to, the first-direction reciprocating movement assembly 30 includes: a first guide rail 31 and a first slider 32. The first guide rail 31 is mounted on the bed body 19, and the first slider 32 reciprocates along the first direction X on the first guide rail 31; a first lead screw 33 and a first slide seat 34. The first slide seat 34 is provided with a first transmission thread hole 35. The first lead screw 33 is threadedly connected to the first transmission thread hole 35.

The output shaft of the first servo motor 36 and the shaft head of the first lead screw 33 can be realized by means such as the gear belt drive shown in the figure. Since the first lead screw 33 is limited to a rotational degree of freedom, and the first slide seat 34 (with the first transmission thread hole 35 fixedly arranged relative to the first slide seat 34) is limited to a translational degree of freedom, the threaded connection between the first lead screw 33 and the first transmission thread hole 35 can convert the rotation of the first lead screw 33 around the first-direction X axis into the movement of the first slide seat 34 along the first direction X.

[0115] Refer to Figure 1 As shown in the figure and refer to Figure 2, the second-direction reciprocating movement assembly 40 includes: a second guide rail 41 and a second slider 42.

A second transmission threaded hole 45 is provided on the second sliding seat 44, and the second lead screw 43 is threadedly connected to the second transmission threaded hole 45. The second lead screw 43 extends along the second direction Y, and the second sliding seat 44 is fixedly connected to the second slider 42; a second servo motor 46, and the second servo motor 46 provides rotation of the second lead screw around the axis of the second direction Y. The output shaft of the second servo motor 46 and the shaft head of the second lead screw 43 can be realized by means such as the gear belt drive shown in the figure. Since the second lead screw 43 is limited to one degree of rotational freedom and the second sliding seat 44 (with the second transmission threaded hole 45 fixedly arranged relative to the second sliding seat 44) is limited to one degree of translational freedom, the threaded connection between the second lead screw 43 and the second transmission threaded hole 45 can convert the rotation of the second lead screw 43 around the axis of the second direction Y into the movement of the second sliding seat 44 along the second direction Y.

[0116] Refer to Figure 1 as shown in combination with reference to Figure 2 , the third-direction rotation assembly 50 includes: a third support seat 51 and a third turntable 52.

Accordingly, the combination of reciprocating movement in the first direction X and reciprocating movement in the second direction Y is achieved.

[0120] Refer to Figure 2As shown, the third rotary servo motor 53 provides a rotary motion about the Z axis in the third direction to the third turntable 52 through a speed reducer. The third rotary servo motor 53 is installed at the third support seat 51. Since the third support seat 51 is erected on the second-direction reciprocating movement assembly 40, accordingly, the combination of the reciprocating movement in the second direction Y and the rotary movement in the third direction Z is achieved.

[0121] Refer to Figure 2 As shown, the composite motion module further includes: a constant-force control component. The constant-force control component is arranged between the second-direction reciprocating movement assembly 40 and the third-direction rotary assembly 50.

The plunger of the force control cylinder 58 pushes out the constant-force control slider 57, so that the bottom 12 or the mouth 13 of the heat-insulating cup is driven to be pushed against the polishing wheel 21. Moreover, the component of the polishing cutting force along the Y axis is kept constant, which is determined by the set pressure of the fluid.
