Description

Technical Field

[0001] The present application belongs to the field of laser processing technology, and more specifically, relates to a position adjustment device and a motor. Background Art

[0002] The speed of the motor on the laser cutting machine is generally adjusted by the reducer, in which the good meshing of the reducer gear and the rack is the guarantee of the machine tool accuracy. The clearance between the reducer gear and the rack is in the optimal state after precise adjustment when the equipment leaves the factory. However, with the acceleration, deceleration and vibration of the equipment during production, the reducer may be displaced. In addition, in order to meet the customer's high requirements for the processing accuracy and processing efficiency of the equipment, the overall weight of the selected drive motor and the matching reducer is also increasing. In this way, the overall inertia of the motor and the reducer will become larger, and the screw tightening mechanism used to fix the reducer will become more and more unreliable. Once the screws are loose, the cutting accuracy of the equipment will be reduced. Utility Model Content

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this application, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0033] See also Figure 1 , Figure 2 and Figure 3 , the position adjustment device provided by the embodiment of the present application is now described. The position adjustment device provided by the embodiment of the present application includes an upper inclined wedge 1, a lower inclined wedge 2 and a pusher 3. The upper inclined wedge 1 includes a supporting surface 11 and a first sliding inclined surface 12, and the lower inclined wedge 2 includes a bottom surface 21 and a second sliding inclined surface 22. The first sliding inclined surface 12 of the upper inclined wedge 1 is in contact with the second sliding inclined surface 22 of the lower inclined wedge 2. The supporting surface 11 of the upper inclined wedge 1 is parallel to and opposite to the bottom surface 21 of the lower inclined wedge 2. The upper inclined wedge 1 is slidably arranged on the second sliding inclined surface 22 of the lower inclined wedge 2 to adjust the distance between the supporting surface 11 of the upper inclined wedge 1 and the bottom surface 21 of the lower inclined wedge 2. The pusher 3 is used to abut against the side wall of the upper inclined wedge 1 to push the upper inclined wedge 1 to slide on the second sliding inclined surface 22 of the lower inclined wedge 2. The length direction of the pusher 3 is parallel to the second sliding inclined surface 22 of the lower inclined wedge 2.

[0034] The position adjustment device of the utility model can be used to adjust the position between the gear 5 and the rack 6 connected to the reducer 4 on the motor, and can also be used to adjust the position of the workpiece during processing.

[0035] The pushing member 3 may be a threaded rod or a screw, preferably a threaded rod.

[0036] The lower inclined wedge 2 of the position adjustment device is installed on the motor by screws, and the reducer 4 is placed on the supporting surface 11 of the upper inclined wedge 1. The pusher 3 is rotated to push the upper inclined wedge 1 to slide on the second sliding inclined surface 22 of the lower inclined wedge 2, and the distance between the supporting surface 11 of the upper inclined wedge 1 and the bottom surface 21 of the lower inclined wedge 2 is adjusted. When the distance between the supporting surface 11 of the upper inclined wedge 1 and the bottom surface 21 of the lower inclined wedge 2 becomes larger, the gear 5 connected to the reducer 4 can be brought close to the rack 6, so that the gear 5 and the rack 6 are more closely engaged, thereby preventing the gear 5 from being loosened due to the vibration of the reducer 4, resulting in a decrease in cutting accuracy, thereby improving the cutting accuracy of the equipment.

[0037] The length direction of the pusher 3 is parallel to the second sliding slope 22 of the lower inclined wedge 2, so that when the pusher 3 pushes the upper inclined wedge 1, the contact point between the pusher 3 and the upper inclined wedge 1 remains unchanged, thereby preventing the upper inclined wedge 1 from wearing the pusher 3 when moving.

[0038] The lower inclined wedge 2 is provided with a mounting portion 23 for threaded connection with the pushing member 3 , and the pushing member 3 is provided with an anti-loosening thread member 31 , which abuts against the mounting portion 23 to prevent the upper inclined wedge 1 from sliding.

[0039] The anti-loosening screw 31 is a nut sleeved on the pusher 3, and the pusher 3 is a screw. The mounting portion 23 is provided with a threaded hole, and the pusher 3 is threadedly connected with the threaded hole of the mounting portion 23. The anti-loosening screw 31 abuts against the mounting portion 23 to increase the friction between the external thread on the pusher 3 and the internal thread of the threaded hole of the mounting portion 23, so as to prevent the pusher 3 from loosening and causing the upper wedge 1 to slide down due to gravity.

[0040] The abutting surface between the mounting portion 23 and the anti-loosening screw member 31 is perpendicular to the second sliding inclined surface 22 of the lower wedge 2 so that the anti-loosening screw member 31 and the mounting portion 23 can be abutted.

[0041] Since the length direction of the pusher 3 is parallel to the second sliding inclined surface 22 of the lower wedge 2, if the side of the mounting portion 23 that contacts the anti-loosening screw 31 is perpendicular to the bottom surface 21 of the lower wedge 2, the contact area between the anti-loosening screw 31 and the mounting portion 23 may be small, and the anti-loosening screw 31 may form a pit on the mounting portion 23 when fixing the pusher 3, thereby wearing the mounting portion 23. However, the abutting surface between the mounting portion 23 and the anti-loosening screw 31 is perpendicular to the second sliding inclined surface 22 of the lower wedge 2, which can increase the contact area between the anti-loosening screw 31 and the mounting portion 23, facilitate the abutment between the anti-loosening screw 31 and the mounting portion 23, and prevent the mounting portion 23 from being worn.

[0042] The contact surface between the upper inclined wedge 1 and the pushing member 3 is perpendicular to the second sliding inclined surface 22 of the lower inclined wedge 2 to increase the contact area between the pushing member 3 and the upper inclined wedge 1 .

[0043] Since the pushing member 3 is preferably a screw, the end of the screw is a plane. Generally, the abutment surface between the upper inclined wedge 1 and the pushing member 3 is perpendicular to the bottom surface 21 of the lower inclined wedge 2, which easily leads to a smaller abutment surface between the pushing member 3 and the upper inclined wedge 1. The pressure exerted by the pushing member 3 on the upper inclined wedge 1 is too large, which may cause pits to appear on the abutment surface of the upper inclined wedge 1 when the upper inclined wedge 1 is pushed. Therefore, in order to increase the abutment surface between the pushing member 3 and the upper inclined wedge 1, the abutment surface between the upper inclined wedge 1 and the pushing member 3 is perpendicular to the second sliding inclined surface 22 of the lower inclined wedge 2, that is, the length direction of the pushing member 3 is perpendicular to the abutment surface between the upper inclined wedge 1 and the pushing member 3.

[0044] A side of the supporting surface 11 of the upper inclined wedge 1 close to the pushing member 3 is provided with an avoidance surface 13 , and the avoidance surface 13 is used to facilitate the retreat of the upper inclined wedge 1 .

[0045] When the upper wedge 1 moves downward on the second sliding slope 22 of the lower wedge 2, that is, when the distance between the supporting surface 11 of the upper wedge 1 and the bottom surface 21 of the lower wedge 2 decreases, the avoidance surface 13 can prevent the protrusion on the reducer 4 or the workpiece from hindering the retreat of the upper wedge 1. The avoidance surface 13 can be a circular arc surface.

[0046] Preferably, the avoidance surface 13 is an inclined surface, the avoidance surface 13 is inclined toward the first sliding inclined surface 12, and the angle between the supporting surface 11 and the avoidance surface 13 is an obtuse angle.

[0047] When the angle between the supporting surface 11 and the avoidance surface 13 is equal to 90°, the upper inclined wedge 1 moves downward on the second sliding inclined surface 22 of the lower inclined wedge 2, that is, when the distance between the supporting surface 11 of the upper inclined wedge 1 and the bottom surface 21 of the lower inclined wedge 2 is reduced, the protrusion on the reducer 4 or the workpiece will jam the upper inclined wedge 1, making it impossible for the upper inclined wedge 1 to retreat; when the angle between the supporting surface 11 and the avoidance surface 13 is less than 90°, a sharp angle will be formed on the upper inclined wedge 1. When the upper inclined wedge 1 retreats, the sharp angle will interfere with the protrusion on the reducer 4 or the workpiece, and the sharp angle may knock off the protrusion, causing damage to the reducer 4 or the workpiece. Therefore, the angle between the supporting surface 11 and the avoidance surface 13 is set to be an obtuse angle.

[0048] Preferably, the angle between the supporting surface 11 and the avoiding surface 13 is 150°. At this angle, the effect of preventing the protrusion on the reducer 4 or the workpiece from hindering the upper inclined wedge 1 from retreating is best.

[0049] A transition arc surface may also be provided between the supporting surface 11 and the avoiding surface 13 to prevent the upper inclined wedge 1 from rubbing against the reducer 4 or a protrusion on the workpiece.

[0050] The angle formed between the supporting surface 11 of the upper inclined wedge 1 and the first sliding inclined surface 12 and the angle formed between the second sliding inclined surface 22 of the lower inclined wedge 2 and the bottom surface 21 are both 8-15°.

[0051] In order to improve the anti-loosening effect of the position adjustment device, the angle between the supporting surface 11 of the upper inclined wedge 1 and the first sliding inclined surface 12 and the angle between the second sliding inclined surface 22 and the bottom surface 21 of the lower inclined wedge 2 cannot be greater than 15°. If it exceeds 15°, the upper inclined wedge 1 will easily slide down.

[0052] However, in order to increase the adjustable range of the distance between the supporting surface 11 of the upper inclined wedge 1 and the bottom surface 21 of the lower inclined wedge 2, the angle formed by the supporting surface 11 of the upper inclined wedge 1 and the first sliding inclined surface 12 and the angle formed by the second sliding inclined surface 22 of the lower inclined wedge 2 and the bottom surface 21 cannot be less than 8°, otherwise the adjustable range of the distance between the supporting surface 11 of the upper inclined wedge 1 and the bottom surface 21 of the lower inclined wedge 2 is too small. When the distance difference between the gear 5 and the rack 6 connected to the reducer 4 is large, the position adjustment device cannot make the gear 5 and the rack 6 mesh, and the cutting accuracy of the equipment cannot be improved.

[0053] Preferably, the angle between the supporting surface 11 of the upper inclined wedge 1 and the first sliding inclined surface 12 and the angle between the second sliding inclined surface 22 of the lower inclined wedge 2 and the bottom surface 21 are both 10°. At this angle, the anti-loosening effect and adjustment range of the position adjustment device are most suitable for adjusting the distance between the gear 5 and the rack 6 on the reducer 4.

[0054] See also Figure 2 and Figure 3 The embodiment of the present application also provides a motor, including the position adjustment device described above, and also including a reducer 4, a gear 5 and a rack 6, the reducer 4 is transmission-connected to the gear 5, the rack 6 is meshed with the gear 5, the reducer 4 is placed on the supporting surface 11 of the upper inclined wedge 1 of the position adjustment device, and the position adjustment device is used to adjust the position of the gear 5 connected to the reducer 4 so that the gear 5 is meshed with the rack 6.

[0055] The motor of the embodiment of the present application includes the position adjustment device in any of the above embodiments, and thus has the beneficial effects brought by the position adjustment device in any of the above embodiments, which will not be elaborated here.

[0056] The motor also includes a motor housing 7, and the position adjustment device is installed on the motor housing 7. The upper inclined wedge 1 of the position adjustment device is provided with an adjustment hole 14 and an anti-loosening abutment portion 15. The anti-loosening abutment portion 15 is inserted into the adjustment hole 14 to be connected to the motor housing 7.

[0057] The adjustment hole 14 is a waist-shaped hole, and the length direction of the waist-shaped hole is parallel to the second sliding inclined surface 22 of the lower inclined wedge 2. The anti-loosening abutment portion 15 can be a threaded rod, which is passed through the adjustment hole 14 and connected to the motor housing 7. The head of the threaded rod abuts against the edge of the adjustment hole 14 to prevent the upper inclined wedge 1 from sliding on the second sliding inclined surface 22 of the lower inclined wedge 2.

[0058] When the pushing member 3 pushes the upper inclined wedge 1, it is necessary to loosen the anti-loosening abutment portion 15. After the upper inclined wedge 1 is positioned, the pushing member 3 is fixed, the anti-loosening threaded member 31 is tightened, and then the anti-loosening abutment portion 15 is tightened, thereby further preventing the upper inclined wedge 1 from sliding on the second sliding inclined surface 22 of the lower inclined wedge 2.

[0059] The above description is only a preferred embodiment of the present application and is not intended to limit the present application. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present application should be included in the protection scope of the present application.
