Description

Technical Field

[0001] The invention relates to the technical field of positioning and adjusting devices, and in particular to an auxiliary positioning and adjusting device for a positioning frame of an electric saw. Background Art

[0002] Electric saws are currently commonly used cutting tools. The motor can drive the blade to move, thereby cutting the workpiece. However, in the actual construction process, there is such a problem: when the existing electric saw performs straight-line cutting, the positioning frame is positioned along the direction of the workpiece to be cut, and the blade and the positioning frame are arranged parallel to each other. However, due to the angle deviation between the blade and the positioning frame, the blade is prone to cutting deviation or cutting without stopping as the cutting distance increases. Summary of the invention

[0003] The present invention solves the technical problem that the blade is easily offset or unable to cut as the cutting distance increases due to the angle deviation between the blade and the positioning frame. By adjusting the reference datum plane for blade cutting and the angle of the blade, the blade and the workpiece are always kept parallel, so that the blade can cut the workpiece in a straight line, and the operation is simple.

[0004] In order to solve the above problems, the present invention provides an auxiliary positioning and adjustment device for an electric saw positioning frame, comprising: a base plate, on which the electric saw is installed, the base plate is provided with an opening, the opening is used to accommodate the electric saw blade, and the base plate is provided with a positioning frame; an angle adjustment device, the angle adjustment device is arranged on the electric saw, and the electric saw blade can be kept parallel to the positioning frame through the angle adjustment device.

[0005] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the electric saw is installed on the bottom plate, and the positioning frame on the bottom plate is the reference reference surface of the electric saw blade when cutting, and the blade cuts along the direction of the positioning frame. When the electric saw blade is parallel to the positioning frame on the bottom plate, and the positioning frame is parallel to the workpiece, the blade is parallel to the workpiece, so that the blade can cut along the straight line of the workpiece, and as the cutting distance increases, the blade is not prone to cutting deviation or cutting motion. Since the electric saw is prone to shaking due to the action of the motor when cutting, if the positioning frame is not set, directly judging whether the blade is parallel to the workpiece is likely to cause a large error and easily deviate from the straight line. Therefore, it is more intuitive and simple to judge the positional relationship between the blade and the workpiece by setting the positioning frame. It only needs to adjust the positional relationship between the positioning frame and the blade before the electric saw cuts, and the positional relationship is adjusted by the angle adjustment device. The angle adjustment device is installed on the electric saw. By adjusting the angle adjustment device, the positioning frame originally inclined to the blade is moved away from or close to the blade, so that the blade and the positioning frame remain parallel, which is easy to operate, convenient and fast.

[0006] In one example of the present invention, the auxiliary positioning and adjusting device further comprises an adjusting plate, the adjusting plate is connected to the bottom plate, and the angle adjusting device is in contact with the adjusting plate.

[0007] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: since the angle adjustment device is fitted with the adjustment plate, when the angle adjustment device moves, the angle adjustment device will drive the adjustment plate to move, the adjustment plate is connected to the bottom plate, and the adjustment plate drives the bottom plate to move, thereby realizing the angle adjustment device to adjust the position relationship between the blade and the bottom plate, so that the blade remains parallel to the bottom plate and the positioning frame. Among them, the adjustment plate has a transmission function, which can simplify the operation steps, save time and effort, and is easy to operate.

[0008] In one embodiment of the present invention, the angle adjustment device is provided with an adjustment hole and an adjustment member, the adjustment member is installed in the adjustment hole, and the adjustment member can rotate in the adjustment hole.

[0009] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the adjusting member is connected with the adjusting hole, and the adjusting member can rotate in the adjusting hole, which is convenient for operation. By rotating the adjusting member, the tightness of the connection between the angle adjustment device and the electric saw can be controlled, thereby adjusting the positional relationship between the angle adjustment device and the electric saw. When the angle adjustment device moves in a direction away from the electric saw blade, the adjustment plate also moves in a direction away from the electric saw blade, so that the positioning frame of the bottom plate moves in a direction close to the electric saw blade; when the angle adjustment device moves in a direction close to the electric saw blade, the adjustment plate also moves in a direction close to the electric saw blade, so that the positioning frame of the bottom plate moves in a direction away from the electric saw blade. By controlling the tightness of the connection between the angle adjustment device and the electric saw, the positional relationship between the blade and the positioning frame can be adjusted at the same time. It is easy to implement, simple in structure, and easy to operate.

[0010] In an example of the present invention, the adjustment hole includes at least one first adjustment hole, in which a first adjustment member is disposed. The first adjustment member can rotate in the first adjustment hole to drive the angle adjustment device to move toward a first direction.

[0011] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the first adjusting member is connected with the first adjusting hole so that the first adjusting member can rotate in the first adjusting hole, thereby the position of the angle adjusting device moves, and the movement direction of the angle device is related to the rotation direction of the first adjusting member in the first adjusting hole, and the movement distance of the angle device is related to the movement distance of the first adjusting member in the first adjusting hole. The rotation direction of the first adjusting member and its movement distance in the first adjusting hole are adjusted according to the offset angle between the blade and the positioning frame. The angle adjusting device is adjusted by rotating the first adjusting member, which is easy to operate and can achieve multiple goals at one stroke. The movement direction and movement distance of the angle adjusting device can be controlled at the same time, thereby driving the adjustment plate to move, so that the blade and the positioning frame do not deviate and remain parallel.

[0012] In one example of the present invention, the first adjustment hole protrudes outward and is provided with a first through hole.

[0013] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the first adjustment hole protrudes outward, and a first through hole is provided at the protrusion, so that the first adjustment member passes through the first through hole, the first adjustment member is installed in the first adjustment hole, and the first adjustment member can rotate in the first through hole, thereby playing the effect of fixing and adjusting the angle adjustment device. In addition, compared with the through hole in which the first adjustment member is installed on a common plane, the length of the first adjustment member exposed outside the first adjustment hole is shortened, which is more conducive to distinguishing the rotation effect and function of the first adjustment hole.

[0014] In one example of the present invention, the adjustment hole also includes at least one second adjustment hole, in which a second adjustment member is arranged. The second adjustment member can rotate in the second adjustment hole to drive the angle adjustment device to move in a second direction, and the second direction is opposite to the movement direction of the first direction.

[0015] Compared with the prior art, the technical effect achieved by adopting the technical solution is as follows: the second adjusting member is connected with the second adjusting hole, so that the second adjusting member can rotate in the second adjusting hole, so that the position of the angle adjusting device moves, and the movement direction of the angle device is related to the rotation direction of the second adjusting member in the second adjusting hole, and the movement distance of the angle device is related to the movement distance of the second adjusting member in the second adjusting hole. The rotation direction of the second adjusting member and the movement distance of the second adjusting member in the second adjusting hole are adjusted according to the offset angle between the blade and the positioning frame. The angle adjusting device is adjusted by rotating the second adjusting member, which is easy to operate and can achieve multiple goals at one stroke. The movement direction and movement distance of the angle adjusting device can be controlled at the same time, thereby driving the adjustment plate to move, so that the blade and the positioning frame do not deviate and remain parallel. In addition, the second adjusting member and the first adjusting member have opposite control directions on the angle adjusting device, and their control directions are distinguished, which further improves the efficiency of angle adjustment, and determines which adjusting member to adjust according to the offset angle between the blade and the positioning frame, which is more universal and flexible.

[0016] In one example of the present invention, the second adjustment hole is provided with a groove, the groove includes a first protrusion, a second through hole is provided in the groove, and an elongated piece is provided on the second adjustment hole, and the extending direction of the elongated piece is consistent with the concave direction of the groove of the second adjustment hole.

[0017] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the second adjustment hole is recessed inwardly and provided with a groove, the groove extends inwardly to form a first protrusion, and a second through hole is provided at the groove, so that the second adjustment member passes through the second through hole, the second adjustment member is installed in the second adjustment hole, and the second adjustment member can rotate in the second through hole, thereby playing a fixing and adjusting effect on the angle adjustment device. And compared with the through hole in which the second adjustment member is installed on a common plane, the length of the second adjustment member exposed outside the second adjustment hole is increased, and the distance the second adjustment member moves in the second adjustment hole is increased, which is more conducive to distinguishing the rotation effect and function of the second adjustment hole. An extension member is provided on the second adjustment hole, and the extension direction of the extension member is consistent with the recessed direction of the recessed groove of the second adjustment hole. When the second adjustment member moves toward the recessed direction of the recessed groove of the second adjustment hole, the extension member can play a fixing role, making the structure more stable.

[0018] In one embodiment of the present invention, a guard is provided on the blade of the electric saw, a fixing seat is provided on the side of the guard facing the angle adjustment device, and the angle adjustment device is installed on the fixing seat.

[0019] Compared with the prior art, the technical effect achieved by adopting this technical solution is as follows: the guard can prevent the electric saw from hurting people during the cutting process. When used in normal construction, the guard is adjusted to a horizontal position and fixed, and the construction is safe and reliable. The angle adjustment device is installed on the fixed seat, and the fixed seat plays a supporting and fixing effect. The fixed seat is arranged on the guard, so that the angle adjustment device is connected to the guard, so that the angle adjustment device can indirectly act on the electric saw blade, which is convenient for operation. An adjustment space is formed between the angle adjustment device and the fixed seat, and the angle adjustment device moves in the adjustment space. The angle adjustment device interacts with the fixed seat, so as to adjust the movement direction of the angle adjustment device, which is easy to achieve. The angle adjustment device is controlled to move closer to or away from the fixed seat, and the angle device drives the adjustment plate to move, and the adjustment plate drives the bottom plate to move, so that the positioning frame moves away from or closer to the fixed seat, and the angle and distance between the positioning frame and the blade are adjusted, so that the positioning frame and the blade remain parallel, which is convenient for operation.

[0020] In an example of the present invention, the fixing seat includes at least one mounting opening, the mounting opening is provided with a notch, the notch is adapted to the first protrusion, the notch is provided with a third through hole, and the third through hole is used to install the second adjusting member.

[0021] Compared with the prior art, the technical effect achieved by adopting this technical solution is that the structure of the fixed seat is adapted to the structure of the angle adjustment device, so that the angle adjustment device can be installed on the fixed seat. The installation notch corresponds to the first protrusion at the groove of the second adjustment hole, the second adjustment member corresponds to the second through hole of the groove, and the second through hole of the groove corresponds to the third through hole at the notch, so that the connection is more stable, so that the second adjustment member can move in the third through hole, so that the second adjustment member can act on the fixed seat, apply pressure to the fixed seat, so that the angle adjustment device moves relative to the fixed seat, and the angle of the angle adjustment device is further adjusted.

[0022] In one example of the present invention, the slot is provided with a fourth through hole, and the fourth through hole is used for mounting the elongated member.

The positional relationship between the blade 20 and the positioning surface 111 is adjusted by an angle adjustment device 120 installed on the electric saw 10. The angle adjustment device 120 can adjust the position of the bottom plate 110 and move the bottom plate 110, thereby adjusting the angle relationship between the blade 20 and the positioning surface 111, so that the positioning surface 111 originally inclined to the blade 20 is away from or close to the blade 20, thereby achieving that the blade 20 and the positioning surface 111 remain parallel.

At this time, the electric saw 10 is fixed on the base plate 110, and a positioning frame is provided on the base plate 110.

The blade 20 can perform a straight-line cutting on the workpiece along the direction of the positioning surface 111.

[0075] When the first adjusting member 124 rotates clockwise in the first adjusting hole 123, the first adjusting member 124 applies pressure to the angle adjusting device 120, and the first adjusting member 124 moves toward the direction close to the fixed seat 31. When the first adjusting member 124 is close to the fixed seat 31, the first adjusting member 124 can no longer move into the fixed seat 31. If the first adjusting member 124 continues to rotate clockwise, the fixed seat 31 will react on the angle adjusting device 120, so that the angle adjusting device 120 moves in the direction away from the fixed seat 31, that is, the angle adjusting device 120 moves in the direction away from the blade 20, and the angle adjusting device 120 drives the adjusting plate 130 to move, and the adjusting plate 30 drives the bottom plate 110 to move, so that the positioning surface 111 moves in the direction close to the blade 20.

[0076] When the second adjusting member 126 rotates clockwise in the second adjusting hole 125, the second adjusting member 126 applies pressure to the angle adjusting device 120, and the extension member 127 on the second adjusting hole 125 fixes the angle adjusting device 120. The extension member 127 passes through the fourth through hole 314, and the extension member 127 is fixed on the fixing seat 31. The second adjusting member 126 passes through the fixing seat 31, so that the angle adjusting device 120 can continuously move toward the direction close to the fixing seat 31, that is, the angle adjusting device 120 moves toward the direction close to the blade 20, and the angle adjusting device 120 drives the adjusting plate 130 to move, and the adjusting plate 30 drives the bottom plate 110 to move, so that the positioning surface 111 moves in the direction away from the blade 20.

[0077] Although the present invention is disclosed as above, the present invention is not limited thereto. Any person skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the scope defined by the claims.
