Description

Technical Field

[0001] This utility model relates to the technical field of workpiece flat chisel processing, specifically a double-blade flat chisel device. Background Technology

[0002] During the flat chisel machining process, unevenness often exists on the workpiece surface due to the inherent characteristics of the material or pre-processing issues. Traditional flat chisel devices use a fixed, fitted structure, which cannot dynamically adjust to the unevenness of the workpiece surface. This easily leads to low machining accuracy and poor surface quality, making it difficult to meet the requirements of precision machining. Subsequent correction processes are often required, increasing production costs and reducing production efficiency.

[0003] Therefore, this utility model provides a double-blade flat shovel device. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide a double-blade flat shovel device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a double-blade flat shovel device, comprising symmetrically arranged base plates, bearing seats fixed to the base plates by horizontal supports, a lifting shaft slidably assembled in the bearing seats by linear bearings, a lower shaft seat fixedly connected to one end of the lifting shaft, and an upper shaft seat detachably connected to the other end of the lifting shaft through a height adjustment screw hole; The lower shaft seat end is equipped with a template, and the template has two sets of sliding grooves on its side. Blade holder A and blade holder B are slidably assembled in the sliding grooves, and a triangular flat blade is fixedly installed on each of blade holder A and blade holder B. A cylinder is fixedly installed on the bearing seat. The output end of the cylinder is connected to the lower shaft seat for transmission. A clamping plate is clamped between the template and the lower shaft seat. A compression spring is elastically provided between the clamping plate and the lower shaft seat. A spherical groove is opened on the clamping plate. A steel ball is movably embedded in the spherical groove. One end of the steel ball abuts against the back side of the template, and the other end of the steel ball is tightened by a locking screw.

[0006] When the workpiece surface is uneven, the template adjusts the angle by rotating the steel ball to ensure that the working surface fits, thereby avoiding processing wobbling and ensuring the blade trajectory. The device can be adapted to workpieces of different thicknesses and heights by adjusting the height of the upper shaft seat and driving the cylinder to expand its application range.

[0007] In a preferred embodiment, the locking screw is threaded through the clamping plate and the lower shaft seat in sequence, and is used to adjust the pre-pressure of the steel ball on the template; the locking screw is also threaded with a locking nut, which is used to lock the adjustment position of the locking screw.

[0008] The technical advantages of adopting the above-mentioned further solutions are as follows: By adjusting the pre-pressure, the tightness of the fit can be adapted according to the hardness of the workpiece material, avoiding insufficient pressure leading to poor fit and excessive pressure damaging the workpiece, thus improving processing adaptability. The locking nut ensures stable pre-pressure during processing, consistent mold fit, reduces processing accuracy deviations caused by pressure fluctuations, and guarantees uniform processing quality.

[0009] In a preferred embodiment, both blade holder A and blade holder B have internally threaded holes on their sidewalls, and blade alignment adjustment screws are internally threaded into the internally threaded holes. The end of the blade alignment adjustment screw abuts against the side of the triangular flat blade in the horizontal direction. By turning the blade alignment adjustment screw, the triangular flat blade can be pushed to move in the blade holder, so as to align and fix the cutting edge positions of the two triangular flat blades.

[0010] The technical advantages of adopting the above-mentioned further solution are: after the double blade edges are aligned, they simultaneously and evenly scrape the workpiece surface, avoiding height differences and step marks caused by blade misalignment. This eliminates the need to disassemble the triangular flat blades; adjustment can be made directly by pushing the blade alignment adjustment screw, simplifying operation, increasing adjustment precision, reducing manual adjustment time and skill requirements, and lowering adjustment costs.

[0011] In a preferred embodiment, an adjustment seat is fixed to the side of the lower shaft seat, and a position display is mounted on the adjustment seat; an adjustment handwheel is rotatably mounted on the position display, and the output end of the adjustment handwheel is connected to the blade holder A or the blade holder B for adjusting the machining depth of the triangular flat blade.

[0012] The technical advantage of adopting the above-mentioned further solution is that by rotating the adjusting handwheel, the cutting depth of the triangular flat blade can be changed by moving the blade holder A or blade holder B up and down. The position display receives the transmission signal from the adjusting handwheel in real time, converts the movement distance (machining amount) into a numerical display, and provides intuitive feedback on the adjustment result, thus avoiding workpiece scrap caused by machining amount deviation.

[0013] In a preferred embodiment, a dust collection hood is installed between the two base plates via an outer mounting plate; the opening of the dust collection hood faces the processing area of ​​the triangular flat blade and is used to collect chips and dust generated during processing.

[0014] The technical advantages of adopting the above-mentioned further solution are: chips and dust generated during processing are sucked in by external dust collection equipment through the opening of the dust hood, preventing them from accumulating in the processing area. This reduces the amount of chips adhering to the workpiece surface or the blade edge, avoiding secondary scratches on the workpiece and accelerated blade wear, and ensuring the cleanliness of the processed surface.

[0015] In a preferred embodiment, a pressure regulating valve is fixedly installed on the bearing housing. The pressure regulating valve is connected to the air inlet pipe of the cylinder through an air connector and is used to regulate the working air pressure when the cylinder pushes the template.

[0016] The technical effect of adopting the above-mentioned further solution is that the cylinder thrust can be adjusted according to the workpiece thickness and material characteristics. For example, the thrust can be increased to ensure a close fit for thick workpieces, and the thrust can be reduced to avoid deformation for thin workpieces, thereby further improving the adaptability of the device to different workpieces.

[0017] In a preferred embodiment, an air inlet is fixedly installed on the side of the lower shaft seat, and an air passage is opened inside the lower shaft seat. One end of the air passage is connected to the air inlet, and the other end of the air passage extends to the processing area of ​​the template and forms an air hole.

[0018] The technical effect of adopting the above-mentioned further solution is that the air passage opened inside the lower shaft seat guides the air source to the air blowing hole in the template processing area. Compressed air is blown directly onto the processing surface and the cutting edge of the blade through the air blowing hole, and the residual fine debris and dust are blown away in time.

[0019] This utility model provides a double-blade flat shovel device. It has the following beneficial effects: The use of steel balls and compression springs allows the template to dynamically adapt to the undulations of the workpiece surface, avoiding the problems of localized missed machining and overpressure scratches caused by traditional fixed bonding structures, ensuring that the machined part after flat chiseling fits the workpiece surface perfectly. The dual blades achieve precise blade alignment via blade alignment adjustment screws. Combined with numerical machining control via an adjustment handwheel and position display, blade holders A and B, located in a groove, synchronously adjust the machining volume of the two sets of blades by adjusting the handwheel and the adjustment screw. The height adjustment screw hole allows the upper shaft seat to quickly adapt to different workpiece heights, reducing debugging time and improving batch production efficiency.

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] like Figures 1-5 As shown, this embodiment provides a technical solution: a double-blade flat shovel device, including a symmetrically arranged base plate 15. The base plate 15 is fixed with a bearing seat 18 by a horizontal support 14. A lifting shaft 17 is slidably assembled in the bearing seat 18 through a linear bearing 20. One end of the lifting shaft 17 is fixedly connected to a lower shaft seat 7, and the other end of the lifting shaft 17 is detachably connected to an upper shaft seat 21 through a height adjustment screw hole 22. A template 2 is assembled at the end of the lower shaft seat 7. Two sets of sliding grooves are opened on the side of the template 2, and blade seats are slidably assembled in the sliding grooves. A24 and B25 are blade holders, each with a triangular flat blade 23 fixedly mounted. A cylinder 12 is fixedly mounted on the bearing seat 18, and the output end of the cylinder 12 is connected to the lower shaft seat 7 for transmission. A clamping plate 4 is clamped between the template 2 and the lower shaft seat 7, and a compression spring 5 is elastically arranged between the clamping plate 4 and the lower shaft seat 7. A spherical groove is formed on the clamping plate 4, and a steel ball 3 is movably embedded in the spherical groove. One end of the steel ball 3 abuts against the back side of the template 2, and the other end of the steel ball 3 is tightened by a locking screw 8. The steel ball 3 has internal threads and is fixed to the lower shaft seat 7 by internal and external threaded screws, and the piston rod threads of the cylinder 12 are connected to the internal and external threaded screws.

[0024] The symmetrically arranged base plate 15 fixes the bearing seat 18 through the horizontal support 14. The linear bearing 20 in the bearing seat 18 provides guidance for the lifting shaft 17, ensuring that the lifting shaft 17 moves along a fixed trajectory. One end of the lifting shaft 17 is fixedly connected to the lower shaft seat 7, and the other end is connected to the upper shaft seat 21 through the height adjustment screw hole 22, so that the position of the upper shaft seat 21 can be finely adjusted to adapt to different workpiece heights. The lower shaft seat 7 is equipped with a template 2 on its side. The template 2 has a sliding groove on its side where the blade holder A24 and blade holder B25 are slidably mounted. The blade holder A24 and blade holder B25 drive the triangular flat blade 23 to move with the template 2. The output end of the cylinder 12 on the bearing seat 18 drives the lower shaft seat 7, which in turn drives the template 2 to rise and fall along the guide of the linear bearing 20, so as to achieve the contact and separation between the template 2 and the workpiece machining surface. The clamping plate 4 between the template 2 and the lower shaft seat 7 is provided with a spherical groove. The spherical groove contains a movable steel ball 3. One end of the steel ball 3 abuts against the back of the template 2, and the other end of the steel ball 3 is tightened by the locking screw 8. With the help of the compression spring 5 between the clamping plate and the lower shaft seat, the template 2 is provided with elastic support and universal adjustment space. When the workpiece surface is uneven, the template 2 can adjust the angle by rotating the steel ball 3 to ensure that the working surface is in contact, thereby avoiding machining shaking and ensuring the blade trajectory. The height of the upper shaft seat 51 is adjusted and the cylinder 12 is used to drive the device to rise and fall, so that the device can be adapted to workpieces of different thicknesses and heights, thus expanding the application range.

[0025] Going further, such as Figure 2 and Figure 5 As shown: The locking screw 8 is threaded through the clamping plate 4 and the lower shaft seat 7 in sequence, and is used to adjust the pre-pressure of the steel ball 3 on the template 2. The locking screw 8 is also threaded with a locking nut 10, which is used to lock the adjustment position of the locking screw 8.

[0026] The locking screw 8 is threaded through the clamping plate 4 and the lower shaft seat 7. Tightening the locking screw changes the clamping force on the steel ball 3, thereby adjusting the pre-pressure of the steel ball on the template 2 and controlling the tightness of the fit between the template 2 and the workpiece machining surface. The locking nut 10, threaded onto the locking screw 8, is tightened to abut against the surface of the lower shaft seat 7 after the pre-pressure is adjusted, locking the position of the locking screw 8 and preventing pre-pressure deviation caused by machining vibration. By adjusting the pre-pressure, the fit tightness can be adapted to the workpiece material hardness, avoiding insufficient pressure leading to poor fit and excessive pressure damaging the workpiece, thus improving machining adaptability. The locking nut 10 ensures stable pre-pressure during machining, consistent template 2 fit, reduces machining accuracy deviations caused by pressure fluctuations, and guarantees consistent machining quality.

[0027] Going further, such as Figures 2-5As shown: Both blade holder A24 and blade holder B25 have internal threaded holes on their side walls, and blade alignment adjusting screws 27 are internally threaded into the internal threaded holes; the end of the blade alignment adjusting screw 27 abuts against the side of the triangular flat blade 23 in the horizontal direction. By turning the blade alignment adjusting screw 27, the triangular flat blade 23 can be pushed to move in the blade holder, so as to align and fix the cutting edge positions of the two triangular flat blades 23.

[0028] The internal threaded holes on the sidewalls of blade holders A24 and B25 are threaded into the blade alignment adjusting screw 27. The end of the blade alignment adjusting screw 27 abuts against the side of the triangular flat blade 23 in a horizontal direction. When the blade alignment adjusting screw 27 is turned, the triangular flat blade 23 can be pushed to move horizontally within the mounting slot of blade holder A24 or blade holder B25 until the cutting edges of the two triangular flat blades 23 are on the same plane or machining trajectory, thus achieving alignment. After the cutting edges of the two blades are aligned, they can be simultaneously flat-shoveled onto the workpiece surface, avoiding height differences and step marks caused by blade misalignment. This eliminates the need to disassemble the triangular flat blades 23; adjustment can be made directly by pushing the blade alignment adjusting screw 27, which is simple to operate and has high adjustment accuracy, reducing manual debugging time and skill threshold, and reducing debugging costs.

[0029] Going further, such as Figures 3-4 As shown: An adjusting seat 26 is fixed on the side of the lower shaft seat 7, and a position display 9 is installed on the adjusting seat 26; an adjusting handwheel 11 is rotatably mounted on the position display 9, and the output end of the adjusting handwheel 11 is connected to the blade holder A24 or the blade holder B25 for adjusting the machining depth of the triangular flat blade 23.

[0030] A position display 9 and an adjustment handwheel 11 are mounted on an adjustment seat 26 fixed to the side of the lower shaft seat 7. The output end of the adjustment handwheel is connected to the blade holder A24 or the blade holder B25. By rotating the adjustment handwheel 11, the blade holder A24 or the blade holder B25 is moved up and down, changing the cutting depth of the triangular flat blade 23. The position display 9 receives the transmission signal from the adjustment handwheel 11 in real time, converts the movement distance (machining amount) into a numerical display, and intuitively provides feedback on the adjustment result, avoiding workpiece scrap caused by machining amount deviation.

[0031] Going further, such as Figures 1-2 As shown, a dust collection hood 1 is installed between the two base plates 15 via an outer mounting plate 13; the opening of the dust collection hood 1 faces the processing area of ​​the triangular flat blade 23 and is used to collect chips and dust generated during processing.

[0032] A dust collection hood 1, mounted between the two base plates 15 via an external mounting plate 13, has its opening facing the processing area of ​​the triangular flat blade 23. Chips and dust generated during processing are sucked in by an external dust collection device through the opening of the dust collection hood, preventing accumulation in the processing area. This reduces chip adhesion to the workpiece surface or blade edge, preventing secondary scratches on the workpiece and accelerated blade wear, ensuring a clean processing surface. It also prevents debris from entering the device, reducing the risk of component jamming and wear, extending the device's lifespan, and lowering maintenance frequency and costs.

[0033] Going further, such as Figure 2 and Figure 5 As shown, a pressure regulating valve 16 is fixedly installed on the bearing housing 18. The pressure regulating valve 16 is connected to the air inlet pipe of the cylinder 12 through the air connector 19 and is used to regulate the working air pressure when the cylinder 12 pushes the template 2.

[0034] The pressure regulating valve 16 on the bearing housing 18 is connected to the air inlet pipe of the cylinder 12 via the air connector 19. Adjusting the pressure regulating valve 16 changes the compressed air pressure input to the cylinder 12, thereby controlling the thrust of the piston rod of the cylinder 12 and adjusting the driving force of the template 2 to fit the workpiece processing surface. This allows the thrust of the cylinder 12 to be adjusted according to the workpiece thickness and material characteristics. For example, increasing the thrust for thick workpieces ensures a close fit, while decreasing the thrust for thin workpieces avoids deformation, further improving the adaptability of the device to different workpieces. This prevents the template 2 from damaging the workpiece due to excessive thrust of the cylinder 12, or from being too weak to ensure a tight fit and affect processing, thus balancing the processing quality.

[0035] Going further, such as Figures 2-5 As shown, an air inlet 6 is fixedly installed on the side of the lower shaft seat 7. An air passage is opened inside the lower shaft seat 7. One end of the air passage is connected to the air inlet 6, and the other end of the air passage extends to the processing area of ​​the template 2 and forms an air hole.

[0036] The air inlet 6 on the side of the lower shaft seat 7 connects to an external air source. The air passage inside the lower shaft seat guides the air source to the air blowing hole in the machining area of ​​the template 2. Compressed air is blown directly onto the machining surface and the cutting edge of the blade through the air blowing hole, promptly blowing away residual fine debris and dust. Air blowing cleaning removes fine debris adhering to the cutting edge and machining surface, further ensuring the cleanliness of the machined surface and preventing small impurities from affecting subsequent machining or assembly.

[0037] Working principle: like Figure 1-5As shown, based on the workpiece thickness, the connection position between the upper shaft seat 21 and the lifting shaft 17 is changed by turning the adjusting screw through the height adjusting screw hole 22 of the upper shaft seat 21, thereby adjusting the overall height of the lower shaft seat 7 and the template 2 to ensure that the working surface of the template 2 and the workpiece machining surface are within the appropriate height range. The locking screw 8 is then turned through the clamping plate 4 and the lower shaft seat 7 in sequence, adjusting the pre-pressure of the steel ball 3 on the template 2 to match the workpiece material hardness; reduce the pressure for soft materials and increase the pressure for hard materials. After adjustment, the locking nut 10 is tightened to lock it in place. Simultaneously, the blade alignment adjusting screw 27 is turned to push the triangular flat blade 23 to move horizontally within the blade holder A24 or blade holder B25, aligning the double blade edges to ensure consistent machining. The dust collection hood 1 is connected to an external dust collection device, the air inlet 6 is connected to an external air source, and the pressure regulating valve 16 is adjusted to a suitable air pressure according to the workpiece characteristics. The position display 9 is reset to zero, ready for machining.

[0038] When the equipment is started, cylinder 12 receives the air circuit signal, the piston rod of cylinder 12 extends, and drives the lower shaft seat 7 to rise and fall along the guide direction of linear bearing 20, which drives the template 2 to approach the workpiece processing surface until the working surface of template 2 contacts the workpiece surface.

[0039] If the workpiece surface is uneven (such as protrusions or depressions), the template 2 is subjected to the reaction force of the workpiece surface, and the steel ball 3 in the spherical groove of the clamping plate 4 rotates in all directions to adjust the angle; at the same time, the compression spring 5 between the clamping plate 4 and the lower shaft seat 7 elastically expands and contracts to compensate for the displacement of the template 2, ensuring that the working surface of the template 2 is always tightly attached to the workpiece surface, without local loose connection or overpressure.

[0040] According to the processing requirements, rotate the adjusting handwheel 11 on the adjusting seat 26 to drive the blade holder A24 or blade holder B25 to move up and down along the sliding groove of the template 2, thereby changing the cutting depth of the triangular flat blade 23; the position display 9 displays the adjustment value in real time to ensure accurate processing; as the workpiece moves, the two blades simultaneously perform flat cutting on the workpiece processing surface.

[0041] During the machining process, the dust hood 1 continuously sucks in the chips and dust generated during cutting to prevent accumulation; the air inlet 6 blows compressed air into the machining area through the internal air passage of the lower bearing 7 to remove small debris attached to the blade edge and workpiece surface, while also assisting in cooling the blade.

[0042] After processing is completed, the piston rod of cylinder 12 retracts, driving the lower shaft seat 7 and template 2 to descend along the linear bearing 20, and the template 2 separates from the workpiece processing surface.

[0043] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
