Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of electric tools, in particular to a high-stability machine base for electric circular saws. BACKGROUND

[0002] An electric circular saw is a tool for sawing operations, mainly composed of an electric motor, a reduction gearbox, a protective cover, an adjusting mechanism, a bottom plate, a handle, a switch, a non-reusable plug, a circular saw blade, etc. It is powered by a single-phase series motor, which then drives the circular saw blade through a transmission mechanism. It has the characteristics of safety and reliability, high work efficiency, etc. The current operation mode of electric circular saws on the market is completely dependent on manual lifting and holding operation. The stability is poor during the initial cutting and cutting process, the requirements for the operator are high, the cover angle cannot be adjusted according to the position of the flying debris, and the functionality is also relatively simple. SUMMARY

[0003] The technical problem to be solved by the present application is that the current electric circular saws on the market completely rely on manual lifting and holding operation, and the stability is poor during the initial cutting and cutting process. The requirements for the operator are high, the cover angle cannot be adjusted according to the position of the flying debris, and the functionality is also relatively simple.

[0004] The technical solution adopted by the present application to solve the technical problem is: a high-stability machine base for electric circular saws, comprising a main machine shell, a lateral protective cover movably assembled on the side wall of the main machine shell, an electrically controlled cutting circular saw installed inside the side wall of the main machine shell, a lateral stability adjusting seat provided on one side of the main machine shell, a side-hung dust collection box installed on the side wall of the lateral stability adjusting seat, and a pull-out dust extraction pipe connected to the inside of the lateral protective cover and installed on the side-hung dust collection box.

[0005] An embedded top guide rail is fixedly assembled on the lateral stability adjusting seat.

[0006] An electric control screw rod for controlling the translation of the main machine shell is installed inside the embedded top guide rail, and the main machine shell is threadedly assembled with the electric control screw rod by being sleeved on the electric control screw rod through an internally threaded mounting block of the bottom integral structure.

[0007] The side wall of the main machine shell has an integral structure of a lateral connecting boss at the connecting end of the lateral protective cover, the lateral protective cover is movably assembled with the main machine shell by being sleeved on the lateral connecting boss, and an angle adjusting support rod is installed between the main machine shell and the lateral protective cover.

[0008] An infrared monitoring module for controlling the angle adjusting support rod is fixedly assembled on the arc-shaped surface on both sides of the lateral protective cover.

[0009] The side-mounted dust collection box has a lateral telescopic hole on its side wall. The horizontal section of the pull-out dust collection pipe is inserted into the lateral telescopic hole and slidably assembled with the side-mounted dust collection box. The section of the pull-out dust collection pipe located inside the side-mounted dust collection box is fixed with an inner guide sealing piston. The outer end of the pull-out dust collection pipe is fixedly connected to the side protective cover through a connecting pipe.

[0010] The lower end of the lateral stabilizing adjustment seat is elastically fitted with a telescopic limiting pin at the apex position, and the upper end of the telescopic limiting pin is fitted with an operating cap.

[0011] A handle for easy control is fixedly mounted on the upper surface of the main unit housing.

[0012] The lower surface of the lateral stabilizing adjustment seat has a bottom expansion groove.

[0013] The bottom expansion groove has inner limiting slots on both sides.

[0014] The beneficial effects of this invention are:

[0015] (1) The high-stability electric circular saw base of the present invention is provided with a lateral stabilizing adjustment seat on one side of the main body housing. The lateral stabilizing adjustment seat limits the position of the entire electric circular saw, thereby improving the stability of the electric circular saw during installation and cutting, and making it easy to operate.

[0016] (2) An embedded top guide rail with a built-in electric control screw fixedly mounted on the upper surface of the lateral stabilizing adjustment seat is used to directly connect and control the main body shell through the electric control screw, which facilitates storage and unfolding.

[0017] (3) By controlling the angle adjustment struts through the infrared monitoring modules on the arc surfaces on both sides of the side shield, the flying debris can be greatly reduced and the blocking effect of the side shield can be improved.

[0018] (4) A side-mounted dust collection box is installed on the side wall of the lateral stabilizing adjustment seat. The pull-out dust collection pipe on the side-mounted dust collection box is connected to the inside of the side protective cover. It can be pulled out synchronously with the movement of the electric circular saw, automatically increasing the dust collection volume. During recycling, the internal material is automatically controlled, and the space layout is reasonable. Attached Figure Description

[0026] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the invention, and therefore only show the components relevant to the invention.

[0027] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0028] Figure 1 , Figure 2 , Figure 3 and Figure 4 The high-stability electric circular saw base shown includes a main housing 1, a lateral protective cover 2 movably mounted on the side wall of the main housing 1, an electrically controlled cutting circular saw 3 installed inside the lateral protective cover 2, a lateral stabilization adjustment seat 4 provided on one side of the main housing 1, a side-mounted dust collection box 5 installed on the side wall of the lateral stabilization adjustment seat 4, and a pull-out dust collection pipe 6 connected to the inside of the lateral protective cover 2 installed on the side-mounted dust collection box 5.

[0029] To facilitate installation and adjustment, an embedded top guide rail 7 is fixedly mounted on the lateral stabilizing adjustment seat 4.

[0030] To facilitate the electronically controlled translation, an electronically controlled lead screw 71 for controlling the translation of the main housing 1 is installed inside the embedded top guide rail 7. The main housing 1 is threaded onto the electronically controlled lead screw 71 via an internally threaded mounting block 8 with an integrated bottom structure.

[0031] The electric control screw 71 controls the internal thread mounting block 8 to move and adjust along the interior of the embedded top guide rail 7 by rotation.

[0032] To facilitate assembly and angle adjustment, the side wall of the main housing 1 has an integrally structured lateral connecting boss 9 at the connection end of the lateral protective cover 2. The lateral protective cover 2 is movably assembled with the main housing 1 by fitting onto the lateral connecting boss 9. An angle adjustment strut 10 is installed between the main housing 1 and the lateral protective cover 2.

[0033] The angle adjustment strut 10 controls the rotation and adjustment of the side shield 2 along the side connecting boss 9 by telescoping. One end of the angle adjustment strut 10 is connected to the outside of the side shield 2, and the other end is connected to the outside of the main housing 1.

[0034] To facilitate infrared control, infrared monitoring modules 11 for controlling the angle adjustment struts 10 are fixedly mounted on the curved surfaces on both sides of the side protective cover 2.

[0035] The infrared monitoring module 11 performs infrared monitoring on both sides of the side protective cover 2. The infrared monitoring methods include infrared temperature measurement or infrared distance measurement. When the infrared monitoring detects that the temperature is higher or the distance is shorter, the infrared monitoring module 11 at that position will control the angle adjustment support rod 10 to extend or retract, thereby changing the angle of the side protective cover 2, thus reducing the gap and improving the blocking efficiency.

[0036] To facilitate synchronous telescopic control, a lateral telescopic hole 51 is provided on the side wall of the side-mounted dust collection box 5. The horizontal section of the pull-out dust collection pipe 6 is inserted into the lateral telescopic hole 51 and slidably assembled with the side-mounted dust collection box 5. The section of the pull-out dust collection pipe 6 located inside the side-mounted dust collection box 5 is fixed with an inner guide sealing piston 61. The outer end of the pull-out dust collection pipe 6 is fixedly connected to the side protective cover 2 through a connecting pipe.

[0037] While the electric control screw 71 rotates and drives the internal thread mounting block 8 to move horizontally, the side protective cover 2 drives the pull-out dust extraction pipe 6 to slide and adjust inside the side telescopic hole 51, and then drives the inner guide sealing piston 61 to slide and adjust inside the side-mounted dust collection box 5. When the pull-out dust extraction pipe 6 is pulled out, the inner guide sealing piston 61 expands the dust collection space inside the side-mounted dust collection box 5. When the pull-out dust extraction pipe 6 is retracted inward, the inner guide sealing piston 61 squeezes the dust collection space inside the side-mounted dust collection box 5 inward, making it easier to squeeze the internal garbage outward.

[0038] To improve the stability of the installation limit, a telescopic limit pin 12 is elastically fitted at the lower end of the lateral stabilizing adjustment seat 4 at the top corner position, and an operating cap 13 is installed at the upper end of the telescopic limit pin 12.

[0039] The lateral stabilizing adjustment seat 4 has a lateral telescopic hole for elastically assembling the telescopic limiting pin 12. The compression spring inside the lateral telescopic hole presses the telescopic limiting pin 12 downward, so that the telescopic limiting pin 12 can be easily inserted into the surface of the material to be cut. The telescopic limiting pin 12 adopts a non-marking nail design, which can greatly reduce its impact on the material surface. The function of the operating cap 13 is that when the lateral stabilizing adjustment seat 4 is placed on the material surface, people can press the operating cap 13 to smoothly insert the telescopic limiting pin 12 into the material, thereby limiting and fixing the lateral stabilizing adjustment seat 4.

[0040] To facilitate manual control and handling, a handle 14 is fixedly mounted on the upper surface of the main unit housing 1 for easy control.

[0041] When the main unit casing 1 is in the storage state, it moves horizontally to the top of the lateral stabilizing adjustment seat 4, and people only need to hold the handle 14 to lift the entire device.

[0042] To accommodate internal functional expansion, a bottom expansion groove 15 is provided on the lower surface of the lateral stabilization adjustment seat 4.

[0043] like Figure 5 and Figure 6 As shown, in order to cooperate with the inner limit, the bottom expansion groove 15 has inner limit slots 16 on both sides.

[0044] Devices for functional expansion, such as bottom tracks for easy translation, can be inserted through the opening on one side of the bottom expansion slot 15. The bottom tracks can eliminate the limitation of the telescopic limiting pin 12, and drive the entire base to translate. Alternatively, a bottom guide plate can be inserted through the opening on one side of the bottom expansion slot 15. After the electric circular saw cuts a strip groove, the longitudinal guide plate at the lower end of the bottom guide plate is inserted into the strip groove, and then translational cutting is performed along the strip groove. The guide wheels inside the bottom guide plate reduce friction.

[0045] Working principle: The equipment is placed on the surface of the material to be cut. The electric circular saw 3 is used to cut a strip-shaped cutting groove on the surface of the material. Finally, the telescopic limiting pin 12 at the lower end of the lateral stabilizing adjustment seat 4 is inserted into the surface of the material. Then, the lateral stabilizing adjustment seat 4 is flipped and attached to the surface of the material. At the same time, the main housing 1 at the upper end of the lateral stabilizing adjustment seat 4 is moved along the embedded top guide rail 7. Simultaneously, the electric circular saw 3 moves and cuts. While moving and cutting, the lateral protective cover 2 drives the pull-out dust extraction pipe 6 to move and extend on one side of the side-mounted dust collection box 5. The external air pump at the end of the side-mounted dust collection box 5 quickly draws the dust inside the lateral protective cover 2 into the side-mounted dust collection box 5.

[0046] Based on the above-described preferred embodiments of the present invention, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the inventive concept. The technical scope of this invention is not limited to the contents of the specification, but must be determined according to the scope of the claims.
