Description

Technical Field

[0001] The utility model relates to the technical field of partial improvement design of cutting saws, in particular to a positioning seat for a plate cutting saw. Background Art

[0002] A hand-held cutting machine, also known as a stone cutting machine or a marble machine, is a machine that can be used to cut materials such as stones, tiles, and woods. It is a tool that uses an electric motor as the power to drive a circular saw blade through a transmission mechanism for sawing operations. It has the characteristics of safety and reliability, reasonable structure, high working efficiency, etc. Corresponding saw blades are selected according to different cutting materials, and a large grip design makes it more comfortable to hold with both hands. When cutting a plate, when the cutting size is small, a positioning member can be directly used as an auxiliary cutting reference for cutting. However, when the cutting size is large, the size of the positioning member often cannot meet the cutting length requirements. At this time, due to the inability to accurately determine the cutting reference during the cutting operation, the cutting size will deviate, directly affecting the subsequent installation quality and the overall appearance.

[0003] In the prior art, the patent with the publication number CN205888241U discloses a hand-held electric circular saw, which includes a machine shell with a driving mechanism inside, an output shaft extending out of the machine shell, a saw blade arranged on the output shaft, a first guard for receiving the saw blade, and a bottom plate. The first guard is fixed to the machine shell. The characteristics are as follows: the electric circular saw further includes a second guard that can surround the serrated part of the saw blade above the bottom plate both when the circular saw is working or stopped. The second guard is fixed to the bottom plate. This hand-held electric circular saw has few components, a simple structure, avoids using structures such as springs for the lower guard, has good reliability, and brings convenience to the overall assembly and design of the circular saw. However, this device does not have a mechanism for auxiliary limiting of the cutting path.

[0004] The patent with the publication number CN216828934U discloses a positioning assembly for a hand-held cutting saw, which includes a hand-held cutting saw. A grip is arranged on one side of the hand-held cutting saw. Connecting blocks are hinged to both side walls of the hand-held cutting saw. A sliding pin is arranged on one side wall of the connecting block. A connecting frame is arranged on one side of the sliding pin. A sliding groove is opened in the connecting frame. The sliding pin is slidably connected in the sliding groove. A limiting mechanism is arranged at the top of the sliding pin, and a limiting mechanism is arranged at the bottom of the connecting frame. A telescopic frame mechanism is connected to one side of the grip. The utility model relates to the technical field of cutting saws. The structure of this device is compact. When cutting materials with the hand-held cutting saw, during the cutting process, due to possible path deviation during manual cutting, the cutting effect is not ideal. The cutting path of the hand-held cutting saw is fixed by a pair of connecting frames and a bottom frame on both side walls of the hand-held cutting saw, and no deviation will occur, resulting in a good cutting effect and bringing convenience to people.

[0005] In the above technical solution, the cutting path of the hand-held cutting saw is fixed by a pair of connecting frames on both side walls of the hand-held cutting saw and the bottom frame. Since a secondary frame is hinged to one side of the bottom frame, the cutting guide path can be extended. The sliding groove inside the connecting frame allows the hand-held cutting saw to slide up and down to cut the material. Although this positioning component can assist in limiting the position during the cutting operation, the overall structural design is still relatively complex and not convenient to operate.

[0006] To solve one of the above problems, the present application provides a positioning seat for a sheet cutting saw. Utility Model Content

[0007] The purpose of the present utility model is to solve the problems existing in the prior art, and a positioning seat for a sheet cutting saw is proposed. By installing a positioning seat on the existing cutting saw, first, the side of the upper positioning edge is closely attached to the existing positioning part to be used as the front cutting reference, and then as the lower positioning edge is inserted into the saw kerf formed by the saw blade cutting, the side is used as the rear cutting reference, so that the positioning operation during cutting can be realized by using the lower positioning edge when the length of the positioning part is insufficient.

[0008] To achieve the above purpose, the present utility model adopts the following technical solution: A positioning seat for a sheet cutting saw, which is fixed on the cutting saw to play a role of self-positioning by relying on the edge. The positioning seat includes a bottom plate, and an installation opening matching the saw blade of the cutting saw is processed on the bottom plate. An upper positioning edge is provided on the upper part of one side of the installation opening of the bottom plate, and a lower positioning edge is provided on the lower part of the other side of the installation opening of the bottom plate. The upper positioning edge and the saw blade are parallel to each other, and the same-side surface of the lower positioning edge and the saw blade is flush;

[0009] A plurality of clamping edges are further provided on the bottom plate, and two adjacent clamping edges form a clamping groove, and the clamping groove is fixedly connected to the installation plate of the cutting saw.

[0010] Further, a side support edge is horizontally extended on the bottom plate as described above, and the side support edge is perpendicular to the lower positioning edge.

[0011] Further, as described above, both the upper positioning edge and the lower positioning edge are perpendicular to the bottom plate.

[0012] Further, as described above, the length directions of both the upper positioning edge and the lower positioning edge are the same as the length direction of the bottom plate.

[0013] Further, as described above, the width of the lower positioning edge is not greater than the thickness of the saw blade.

[0014] Further, as described above, the height of the lower positioning edge is greater than the cutting depth of the saw blade.

[0015] Further, the card edges described above include a first card edge, a second card edge, a third card edge, and a fourth card edge with the same structure. The first card edge and the second card edge are arranged opposite to each other, and the third card edge and the fourth card edge are arranged opposite to each other.

[0016] Further, the first card edge and the second card edge described above form a first card slot of the upper opening cavity, and the third card edge and the fourth card edge form a second card slot of the upper opening cavity. The first card slot and the second card slot have the same shape and structure.

[0017] Further, the bottom plate described above includes a mounting plate and fixing plates located on both sides of the mounting plate. A first strip-shaped groove is machined on the mounting plate, and the position of the first strip-shaped groove corresponds to that of the card slot and is fixedly connected by bolts and nuts.

[0018] Further, a second strip-shaped groove and an avoidance position are machined on the fixing plate described above. The second strip-shaped groove is in threaded connection with a threaded hole machined on the body of the cutting saw, and the avoidance position is at the lower part of the body. The cutting saw further includes a motor, the motor is installed on one side of the body and drives the saw blade at a reduced speed, and a battery pack is installed at the handle end of the body, and the battery pack is electrically connected to the motor.

[0019] Compared with the prior art, the beneficial effect of the present utility model is that: by installing a positioning seat on the existing cutting saw, first using the side of the upper positioning edge to closely adhere to the existing positioning part to be close to the edge as the front cutting reference, and then inserting the lower positioning edge into the saw kerf formed by the saw blade cutting to be close to the edge as the rear cutting reference, it can realize the positioning operation during cutting by using the lower positioning edge when the length of the positioning part is insufficient, meet the use requirements in the case where the cutting length of the plate is long while the size of the existing positioning part is short, can quickly be close to the edge for positioning, and the processing size is stable and reliable.

[0020] The function of the bottom plate is to support the entire cutting saw. When the saw blade cuts off the part of the plate that needs to be cut off, the bottom plate is placed on the remaining part of the plate, playing an auxiliary supporting role in the horizontal direction. The function of the side supporting edge is to assist in supporting. When the part below the bottom plate is the part of the plate that needs to be cut off, if this part has no workbench support and will sink, at this time, the bottom plate itself needs to be suspended, and it can only play an auxiliary supporting role in the horizontal direction by carrying on the plate through the side supporting edge.

[0031] For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0033] Embodiment 1

[0034] Referring to Figure 1-7 As shown, a positioning seat of a plate cutting saw of the present utility model. The positioning seat 1 is fixed on the cutting saw 3 to play a role of self-positioning against the edge. The cutting saw 3 is an existing device and can be operated by hand. Generally, a mounting plate 20 is fixedly connected to the bottom, and a saw blade 31 passes through the mounting plate 20 for cutting the plate. The mounting plate 20 is positioned against the edge through a positioning member as a cutting reference. The positioning member is generally a plate member. When the side of the mounting plate 20 closely adheres to the positioning member and moves, the saw blade 31 can be driven to cut according to a set track. When the length of the positioning member meets the cutting length requirement, the cutting saw 3 with the mounting plate 20 can meet the use requirement. On the contrary, when the length of the positioning member is short and cannot meet the positioning requirement of the mounting plate 20, the existing cooperation between the mounting plate 20 and the positioning member cannot complete the long-distance cutting operation.

[0035] Based on the situation that the use between the long-distance cutting operation and the shorter positioning member cannot meet the requirements as described above, the improvement of this application lies in adding a positioning seat 1 below the mounting plate 20. The positioning seat 1 includes a bottom plate 14, and an installation opening 10 matching the saw blade 31 of the cutting saw 3 is machined on the bottom plate 14. The function of the installation opening 10 is to leave space for the installation of the saw blade 31. On the upper part of one side of the installation opening 10 of the bottom plate 14, there is an upper positioning edge 11, and on the lower part of the other side of the installation opening 10 of the bottom plate 14, there is a lower positioning edge 12. Both the upper positioning edge 11 and the lower positioning edge 12 are straight plates. The upper positioning edge 11 is parallel to the saw blade 31, and the moving direction of the saw blade 31 during cutting is a straight line. The lower positioning edge 12 is flush with the same-side surface of the saw blade 31, that is, the lower positioning edge 12 and the same-side surface direction of the saw blade 31 are coplanar. With this design, the upper positioning edge 11 can be used as the front-end positioning reference surface, and the lower positioning edge 12 can be used as the rear-end positioning reference surface. The function of the upper positioning edge 11 is the same as the side-by-side positioning function of the mounting plate 20 before improvement. The lower positioning edge 12 is inserted into the saw kerf formed by front-end positioning on the plate and against one side surface of the saw kerf as the rear-end cutting reference. In this way, the moving direction of the cutting saw 3 moves forward along the direction of the already formed saw kerf, and there is no need to continue using the positioning member. The structure is ingenious, simple and practical. Multiple clamping edges are also provided on the bottom plate 14, and two adjacent clamping edges form a clamping groove. The clamping groove is fixedly connected to the mounting plate 20 of the cutting saw 3. Through the connection and fixation between the clamping groove and the mounting plate 20, there is no need to drill holes in the bottom surface of the bottom plate 14, and the bottom surface of the bottom plate 14 is flat, and the stability of the support and translation operations is good.

[0036] Embodiment 2

[0037] Referring to Figure 1-7 As shown, on the basis of the technical solution of Embodiment 1, for a positioning seat of a plate cutting saw, a side support edge 13 horizontally extends from the bottom plate 14, and the side support edge 13 is perpendicular to the lower positioning edge 12. As Figure 4 shown, the side support edge 13 is located on the left side of the bottom plate 14 and is perpendicular to the lower positioning edge 12, and its function is to assist in supporting. Combining Figure 5 with the installation schematic diagram, when the saw blade 31 cuts the plate, it can cut off the plate on the left or right side of the saw blade 31. In the conventional use operation, the plate is first clamped and fixed with a fixture, and generally the part of the plate that needs to be retained is clamped. When it is necessary to cut off the part of the plate on the left side of the saw blade 31, the bottom plate 14 is located above the clamped part of the plate, and the bottom plate 14 plays the role of supporting and translating the entire cutting saw 3 at this time; when it is necessary to cut off the part of the plate on the right side of the saw blade 31, the bottom plate 14 is located above the unclamped part of the plate, and the bottom plate 14 cannot play the role of supporting and translating the entire cutting saw 3 at this time, while the side support edge 13 is located above the clamped part of the plate at this time and can play the role of assisting in supporting.

[0038] Example 3

[0039] Refer to Figure 1-7 As shown, on the basis of the technical solutions of Example 1 or Example 2, a positioning seat of a sheet cutting saw, combined with Figure 1-2 it can be known that the upper positioning edge 11 and the lower positioning edge 12 are both perpendicular to the bottom plate 14 to meet the use requirements of side edge positioning. It can be seen from Figure 1 that the length directions of the upper positioning edge 11 and the lower positioning edge 12 are the same as the length direction of the bottom plate 14, that is, the stretching direction of the profile of the positioning seat 1.

[0040] Furthermore, the width of the lower positioning edge 12 is not greater than the thickness of the saw blade 31. It is necessary to ensure that the lower positioning edge 12 can be inserted into the saw kerf formed by the saw blade 31 on the sheet, so as to use the saw kerf as the reference for the side edge positioning of the lower positioning edge 12. For the width of the upper positioning edge 11, there is no specific limitation, as long as it is parallel to the saw surface of the saw blade 31, it can be coplanar or non-coplanar.

[0041] Furthermore, the height of the lower positioning edge 12 is greater than the cutting depth of the saw blade 31, that is, the height of the lower positioning edge 12 is greater than the depth of the saw kerf formed by the saw blade 31 on the sheet.

[0042] Furthermore, the clamping edges include a first clamping edge 151, a second clamping edge 152, a third clamping edge 161 and a fourth clamping edge 162 with the same structure. The first clamping edge 151 and the second clamping edge 152 are arranged oppositely, and the third clamping edge 161 and the fourth clamping edge 162 are arranged oppositely. Among them, the first clamping edge 151 and the second clamping edge 152 form a first clamping groove with an upper opening cavity, and the third clamping edge 161 and the fourth clamping edge 162 form a second clamping groove with an upper opening cavity. The shape and structure of the first clamping groove and the second clamping groove are the same. In addition, the bottom plate 14 includes a mounting plate 20 and fixing plates 21 on both sides of the mounting plate 20. A first strip-shaped groove is processed on the mounting plate 20. The position of the first strip-shaped groove corresponds to that of the clamping groove and is fixedly connected by bolts and nuts. Refer to Figure 5-7 As shown, the bolt fastens the nut between the clamping groove and the mounting plate 20, and the nut is located in the clamping groove to avoid using connecting parts on the bottom plate 14. As Figure 5 shown, a second strip-shaped groove and an avoidance position 212 are processed on the fixing plate 21. The second strip-shaped groove is in threaded connection with the screw holes processed on the fuselage 34 of the cutting saw 3, and the avoidance position 212 is located at the lower part of the fuselage 34; Refer to Figure 6-7It can be seen that the cutting saw 3 further includes a motor 33. The motor 33 is installed on one side of the fuselage 34 and drives the saw blade 31 at a reduced speed. The battery pack 32 is installed at the end of the handle 341 of the fuselage 34. The battery pack 32 is electrically connected to the motor 33. The motor 33 is equipped with a reducer, and the output shaft of the reducer is connected to the rotating shaft of the saw blade 31. The cutting function of the cutting saw 3 is a mature technology. The above-mentioned battery pack 32, motor 33, unsubmitted switch button, built-in control panel, etc. will not be elaborated here.

[0043] In the device of the present utility model, the assembly and mating relationships of the various components involved, the battery pack 32, motor 33, reducer and its control software of the cutting machine are prior art or materials. Those skilled in the art can directly purchase or customize them from the market according to the required product models and specifications.

[0044] The electrical components mentioned in the text are all electrically connected to the external main controller and 220V mains or industrial electricity, and the main controller can be a conventional known device such as a computer that plays a control role.

[0045] The above are only the preferred specific embodiments of the present utility model. The well-known specific structures and characteristics and other common knowledge are not described in detail here. For those skilled in the art, it is obvious that the present utility model is not limited to the details of the above embodiments, and can be implemented in other specific forms without departing from the spirit or basic characteristics of the present utility model. Therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution of the present utility model and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
