Description

Technical Field

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

[0002] Grinding machines can be classified into handheld, ride-on, and self-propelled types according to their structure. Among them, ride-on grinding machines require an operator to control the operation of the grinding machine through a handlebar. Since grinding time is generally long, operators need to operate the grinding machine for extended periods. When operators of different heights take turns, the fixed position of the handlebar due to their different heights makes it inconvenient for shift workers to operate the machine. Long working hours cause discomfort to the operators and make them more prone to fatigue. 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 handrail adjustment device is provided. This application can adjust the position of the handrail, so that shift workers of different heights can adjust the position of the handrail according to their own needs, thereby making the operation more comfortable for the operator.

[0004] To achieve the above technical objectives, the technical solution adopted in this application is as follows:

[0005] A grinding machine handle adjustment device, comprising:

[0006] The support base includes a first connecting plate and a second connecting plate. The second connecting plate consists of two pieces. The first connecting plate has a first side and a second side that are arranged opposite to each other along the width direction. A second connecting plate is fixedly connected to the first side and a second connecting plate is fixedly connected to the second side. The second connecting plate is provided with a first shaft hole and a first pin hole.

[0007] The power unit is a linear output power unit, and one end of the power unit is rotatably connected to a first shaft hole provided on a second connecting plate through a first connecting shaft.

[0008] The linkage bracket has one end rotatably connected to the first pin hole provided on the second connecting plate, and the other end rotatably connected to the positioning base, which is fixedly installed on the grinder. The linkage bracket is also rotatably connected to the other end of the power device.

[0009] This application has at least the following beneficial effects:

[0010] The position of the handrail of the grinding machine in this application can be adjusted. Specifically, by extending and retracting the power device, and by rotating both ends of the power device, the linkage bracket can be rotated. When the linkage bracket rotates, it drives the bracket base to move. If the handrail is fixed on the bracket base, the movement of the handrail can be controlled, thereby adapting to the operation of operators of different heights and maintaining the operator's operating comfort.

The power device 30 of this application is a linear output power device. Preferably, the power device 30 can be a cylinder or an electric push rod. One end of the power device 30 is rotatably connected to the first shaft hole 45 on the second connecting plate 42 via the first connecting shaft 31. That is, the power device 30 and the support base 40 are rotatably connected. There are two sets of linkage brackets 50. One end of each linkage bracket 50 is rotatably connected to a first pin hole 44 on the second connecting plate 42, and the other end of each linkage bracket 50 is rotatably connected to the positioning base 20. The two sets of linkage brackets 50 form a parallelogram structure. The positioning base 20 is fixedly installed on the grinder 100. The linkage bracket 50 is also rotatably connected to the other end of the power device 30. That is, the power device 30 can rotate the linkage bracket 50 during the extension and retraction process.

[0023] This application solves the problem of adaptability for operators of different heights by adding an adjustment device to the existing handrail. Specifically, this application uses the extension and retraction of the power device 30, which can rotate at both ends, thereby driving the two sets of linkage brackets 50 to rotate. When the linkage brackets 50 rotate, they drive the bracket base 40 to move. If the bracket base 40 is equipped with the handrail body 10, then the handrail body 10 can also be height adjusted.

[0024] In a preferred embodiment of this application, a handrail base 11 is fixed on the first connecting plate 41, and a handrail body 10 is mounted on the handrail base 11. Preferably, the first connecting plate 41 and the handrail base 11, and the handrail base 11 and the handrail body 10 are both fixedly connected by screws. To enable the handrail body 10 to be adjusted forward and backward, a handrail slider 60 is also added between the first connecting plate 41 and the handrail base 11. Specifically, the first connecting plate 41 is provided with a plurality of first screw holes 46, preferably four. The handrail slider 60 is provided with four first connecting holes. The handrail slider 60 is fixedly connected to the first connecting plate 41 by screws screwed into the first connecting holes and the first screw holes 46, that is, the handrail slider 60 and the first connecting plate 41 are fixedly connected by four screws. Preferably, the handrail slider 60 of this application is provided with a slide rail 61. The slide rail 61 can be located in the middle of the upper surface of the handrail slider 60, or on both sides of the upper surface of the handrail slider 60. Preferably, the slide rail 61 can be located in the middle of the upper surface of the handrail slider 60, and the side of the handrail slider 60 has a convex shape. Preferably, the lower surface of the handrail base 11 is provided with a sliding groove, and the slide rail 61 and the sliding groove cooperate with each other, so that the handrail base 11 can slide on the handrail slider 60. In order to fix the position of the handrail base 11 on the handrail slider 60, the side of the handrail base 11 of this application is provided with a second screw hole, and a matching rotating handle 62 is provided in the second screw hole. The handrail base 11 is locked and fixed on the handrail slider 60 by rotating the handle 62.

[0025] In a preferred embodiment of this application, the number of linkage brackets 50 is two sets, and the number of first pin holes 44 provided on the second connecting plate 42 is two. Both sets of linkage brackets 50 are rotatably connected to the second connecting plate 42 by pins 43 inserted into the first pin holes 44. Preferably, when the two sets of linkage brackets 50 rotate, the two sets of linkage brackets 50 remain parallel to each other. Each set of linkage brackets 50 in this application includes two connecting strips 51. The two connecting strips 51 have the same structure. One end of the two connecting strips 51 is connected by a first connecting sleeve 53. The first connecting sleeve 53 is rotatably connected to the pin 43, and the pin 43 is fixedly connected to the second connecting plate 42. In this way, one end of the two connecting strips 51 and the second connecting plate 42 form a rotatable connection. To enable the other end of the linkage bracket 50 of this application to also form a rotatable connection, the other end of the connecting strip 51 of this application is connected through a second connecting sleeve 52. A rotatable bushing 21 is provided inside the second connecting sleeve 52. The bushing 21 is connected to the positioning base 20 by bolts 22. The other end of the connecting strip 51 of this application can rotate on the positioning base 20 through the bushing 21 and the second connecting sleeve 52, thereby allowing the other end of the linkage bracket 50 to rotate on the positioning base 20. The connecting strip 51 of this application also has an extension 54, on which a second shaft hole 55 is provided. The extension 54 is rotatably connected to the other end of the power device 30 through a second connecting shaft 32 inserted into the second shaft hole 55. One end of the connecting strip 51 of this application has a limiting groove 56, which forms a limiting end 57 at the end of the connecting strip 51. The limiting end 57 cooperates with the first connecting shaft 31, thus providing a certain limiting effect on the position of the handrail body 10.
