Description

Technical Field

[0001] This application relates to the field of grinding machine equipment technology, and in particular to a grinding machine handle angle adjustment device. Background Technology

[0002] When changing operators of a grinding machine, the handle height needs to be adjusted due to differences in operator height, making operation easier. Current grinding machine handles are fixed with a pivot pin, meaning they can only be fixed in a single, pre-defined position. This results in the handle height not being adequately adapted for operators of different heights; in other words, the current pivot pin-fixed handle design has poor adaptability. Summary of the Invention

[0003] The technical problem to be solved by this application is to address the shortcomings in the above-mentioned background technology. To this end, a grinding machine handle angle adjustment device is provided. This application can adjust the grinding machine handle at multiple angles, thereby accommodating operators of different heights to use the grinding machine.

[0006] A connecting cylinder having a first end and a second end disposed opposite to each other along the length direction, and having an inner wall and an outer wall disposed opposite to each other along the thickness direction, with a handle body fixedly connected to the outer wall;

[0007] Friction plates, wherein there are a plurality of friction plates, and the plurality of friction plates are disposed at the first end and / or the second end of the connecting cylinder, and the friction plates are provided with through holes;

[0008] A friction plate fixing base, the friction plate fixing base including a base fixing plate and a connecting sleeve fixedly connected to the base fixing plate, the friction plate being fitted onto the connecting sleeve;

[0009] The locking handle includes a handle body and a lead screw fixed on the handle body. The lead screw passes through the friction plate fixing base, the friction plate, and the connecting cylinder and is threadedly connected to the fastener. The spacing between several friction plates is controlled by rotating the handle body.

[0010] This application has at least the following beneficial effects:

[0011] Compared to the existing handle's pin and pin hole angle adjustment structure, this application uses a friction plate to fix the handle angle, thereby achieving "stepless" adjustment of the handle angle and meeting the needs of operators of different heights for multi-angle adjustment of the handle.

[0020] Please see Figures 1 to 3 The embodiments of this application include:

[0021] This application discloses a grinding machine handle angle adjustment device, including: a connecting cylinder 10, a friction plate 30, a friction plate fixing base 40, and a locking handle 50. The connecting cylinder 10 is a hollow cylindrical structure, specifically having a first end 11 and a second end 12 arranged opposite each other along its length. The connecting cylinder 10 has a certain thickness, specifically having an inner wall 13 and an outer wall 14 arranged opposite each other along its thickness direction. The connecting cylinder 10 is used to form a rotatable connection between the handle body 20 and the frame 60. The friction plate fixing base 40 includes a base fixing plate 41 and a connecting sleeve 42 fixedly connected to the base fixing plate 41. The connecting sleeve 42 is a hollow tubular structure, used to fit the friction plate 30 onto the connecting sleeve 42. To allow the friction plate 30 to be installed on the connecting sleeve 42, the friction plate 30 has a through hole, and the friction plate 30 can rotate on the connecting sleeve 42. The friction plates 30 of this application are a plurality of ones. After the plurality of friction plates 30 are installed on the friction plate fixing base 40, the friction plate fixing base 40 is disposed on at least one end of the connecting cylinder 10, such as on the first end 11 and / or the second end 12. The locking handle 50 of this application includes a handle body 51 and a lead screw 52 fixed on the handle body 51. The lead screw 52 passes through the friction plate fixing base 40, a plurality of friction plates 30 and the connecting cylinder 10 and is threadedly connected to the fastener. The friction plate fixing base 40 and the fastener are located at both ends of the connecting cylinder 10. That is, if the friction plate fixing base 40 is located at the first end 11 of the connecting cylinder 10, the fastener is located at the second end 12 of the connecting cylinder 10. By rotating the handle body 51, the lead screw 52 is driven to rotate, and the lead screw 52 tightens or loosens the fastener, thereby controlling the spacing between the plurality of friction plates 30. This allows the friction plates 30 to be controlled to move or remain stationary. When the handle body 20 needs to be rotated, the spacing between the plurality of friction plates 30 is appropriately loosened. When the handle body 20 needs to be fixed, the spacing between the plurality of friction plates 30 is reduced to ensure the friction between the plurality of friction plates 30.

[0022] This application controls the rotation and stillness of the handle body 20 by rotating the locking handle 50 to control the spacing between several friction plates 30, thereby achieving the purpose of "stepless" adjustment of the angle of the handle body 20. Compared with the prior art that uses the cooperation of pins and pin holes, the adjustment of this application is not only convenient, but also has a wider range of angle selection.

[0023] In a preferred embodiment of this application, the friction plates 30 are divided into two groups. One group of friction plates 30 is disposed at the first end 11 of the connecting cylinder 10, and the other group of friction plates 30 is disposed at the second end 12 of the connecting cylinder 10. Similarly, this application has two friction plate fixing bases 40. One friction plate fixing base 40 is used to install one group of friction plates 30, and the other friction plate fixing base 40 is used to install another group of friction plates 30. By setting two groups of friction plates 30 and friction plate fixing bases 40, the entire device can be made more stable. Moreover, the two groups of friction plates 30 and friction plate fixing bases 40 can also increase the friction force during locking, making the adjustment of the handle body 20 safer. Preferably, the friction plate 30 of this application has a structure that is larger at one end and smaller at the other. Specifically, the friction plate 30 includes a rotating part 31 and a connecting part 32, wherein the rotating part 31 is wider than the connecting part 32, making the friction plate 30 teardrop-shaped. Both the rotating part 31 and the connecting part 32 of this application are provided with through holes. The through holes in the rotating part 31 are to allow the friction plate 30 to rotate on the friction plate fixing base 40, and the through holes in the connecting part 32 are to allow several friction plates 30 to be connected together. The connecting parts 32 of adjacent friction plates 30 in the same group of this application are staggered, and the connecting parts 32 of spaced friction plates 30 in the same group of this application are oriented in the same direction. That is, the connecting parts 32 of adjacent friction plates 30 in the same group form two directions, wherein one The connecting part 32 of the friction plate 30 in one direction is connected to the handle body 20 by bolts, and the connecting part 32 of the friction plate 30 in the other direction is connected to the frame 60 by bolts. The rotating part 31 of the friction plate 30 can rotate on the connecting sleeve 42 on the friction plate fixing base 40, thereby forming a rotatable structure between the handle body 20 and the frame 60. When it is necessary to adjust the angle between the handle body 20 and the frame 60, the distance between the friction plates 30 is increased by rotating the locking handle 50, thereby reducing the friction between the friction plates 30 and allowing the handle body 20 to be rotated. When it is necessary to fix the handle body 20 and the frame 60 relative to each other, the locking handle 50 is rotated in the opposite direction to reduce the distance between the friction plates 30, thereby increasing the friction between the friction plates 30. To ensure stability and prevent deformation between the spacer friction plates 30, friction plate washers 33 are provided between the spacer friction plates 30 in this application. The thickness of the friction plate washers 33 is the same as the thickness of the friction plates 30, ensuring that the friction plate washers 33 can support the spacer friction plates 30. The spacer friction plates 30 are connected by friction plate bushings 34 inserted into the through holes on the connecting part 32. The friction plate bushings 34 further protect the friction plates 30 from deformation.

[0024] In a preferred embodiment of this application, the fastener is a friction plate fixing base 40 or a nut. When the locking handle 50 is rotated, the distance between the fastener and the locking handle 50 can be increased or decreased, thereby controlling the increase or decrease of the distance between the friction plates 30. Preferably, the fastener is a friction plate fixing base 40, and the friction plate fixing base 40 is provided with a screw hole that matches the lead screw 52. By controlling the rotation of the lead screw 52, ​​the movement of the fastener can be controlled.

[0025] In a preferred embodiment of this application, the friction plate fixing base 40 is provided with a first through hole 43. Specifically, the base fixing plate 41 is provided with a first through hole 43, and there are at least two first through holes 43. Preferably, there are six first through holes 43. The friction plate fixing base 40 is fixedly connected to the frame 60 by a first screw 44 inserted into the first through hole 43. The friction plate fixing base 40 is provided with a second through hole 45. Preferably, the base fixing plate 41 is provided with a second through hole 45. Preferably, the shape of the base fixing plate 41 is approximately the same as that of the friction plate 30. The friction plate fixing base 40 is fixedly connected to the frame 60 by a second screw 46 inserted into the second through hole 45 and the through hole on the connecting part 32. The frame 60 is provided with a screw hole 61, which matches the second screw 46.

[0026] In a preferred embodiment of this application, the first end 11 and / or the second end 12 of the connecting cylinder 10 are provided with plugs 70. Preferably, both the first end 11 and the second end 12 of the connecting cylinder 10 are provided with plugs 70. The plug 70 has a convex cross-section and a through hole in the center of the plug 70 for the lead screw 52 to pass through. The smaller end of the plug 70 is inserted into the interior of the connecting cylinder 10. Preferably, the smaller end of the plug 70 is press-fitted with the inner wall 13 of the connecting cylinder 10, and the larger end of the plug 70 contacts the friction plate 30, thereby supporting the friction plate 30 and preventing the friction plate 30 from being squeezed and deformed.

[0027] The above are merely preferred embodiments of this application. The scope of protection of this application is not limited to the above embodiments. All technical solutions falling within the scope of this application's concept are within the scope of protection of this application. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principles of this application should be considered within the scope of protection of this application.
