Description

Technical Field

[0001] This utility model relates to the field of saw blade grinding technology, specifically a reciprocating saw blade grinding device with high stability. Background Technology

[0002] A saw blade is a thin, round tool used for cutting various materials. It is typically made of metal (such as high-speed steel or tungsten carbide) or cemented carbide, and has serrated edges. Depending on their application, saw blades can be categorized as woodworking saw blades, metal cutting saw blades, stone saw blades, etc. The shape, angle, and arrangement of the teeth vary depending on the material properties. Woodworking saw blades have a larger tooth pitch to reduce resistance, while metal saw blades have denser teeth for better wear resistance. Some saw blades have surface coatings (such as titanium alloys) to enhance durability. Installation methods include center-hole fixing (such as in circular saws and angle grinders) or edge attachment (such as in band saws).

[0003] For example, patent announcement number CN212823111U discloses a saw blade grinding device, including a worktable, a lead screw, and a handle. A frame column is welded below the worktable, and an operation panel is connected to one side wall of the worktable by screws. A slide is provided above the worktable, and the lead screw is located in the middle of the upper part of the slide. One end of the lead screw is connected to a handle, and a slider is located in the middle of the lead screw. A rotating tube is located above the slider. The beneficial effects are: by setting up a handle, lead screw, slide, slider, rotating tube, and handle, this utility model not only enables sliding grinding of the saw blade, avoiding grinding difficulties caused by inconvenient sliding, but also enables rotating grinding of the saw blade, avoiding low grinding efficiency caused by slow grinding speed, thus improving the working efficiency of the saw blade grinding device.

[0004] Because the shape and movement of reciprocating saw blades are different from those of circular saw blades, the grinding devices described above are only suitable for fixing and grinding circular saw blades and cannot meet the grinding needs of reciprocating saw blades (strip saw blades). Therefore, the market urgently needs to develop a highly stable reciprocating saw blade grinding device to help people solve existing problems. Utility Model Content

[0005] The purpose of this invention is to provide a highly stable reciprocating saw blade grinding device to solve the problem mentioned in the background art that, due to the different shape and movement of reciprocating saw blades compared to circular saw blades, existing grinding devices are only suitable for fixing and grinding circular saw blades and cannot meet the grinding needs of reciprocating saw blades (strip saw blades).

[0006] To achieve the above objectives, this utility model provides the following technical solution: a reciprocating saw blade grinding device with high stability, comprising a support plate, a fixed seat vertically fixedly connected to the middle of the upper surface of the support plate, a linear guide rail fixedly connected to the middle of the upper surface of the fixed seat, a U-shaped clamp connected to the front end of the upper end of the linear guide rail, clamping plates provided on both sides of the middle of the upper end of the U-shaped clamp, adjusting seats fixedly connected to the upper surface of the support plate and to the middle of both sides of the fixed seat, sliding seats connected to the upper ends of the two adjusting seats, oblique drive motors fixedly connected to the upper ends of the two sliding seats, the two drive motors being mirror-shaped and their output shafts fixedly connected to a grinding disc.

[0008] Preferably, electro-hydraulic rods are fixedly connected to the front and rear ends of the middle part of both sides of the U-shaped clamp, and the telescopic ends of the two electro-hydraulic rods on both sides of the U-shaped clamp extend into the U-shaped clamp and are fixedly connected to the outer end faces of the two clamping plates respectively.

[0009] Preferably, both of the upper surfaces of the two adjusting seats are provided with T-shaped limiting slide grooves, and the middle of the two T-shaped limiting slide grooves are rotatably connected to a rotating shaft. Both sides of the rotating shaft are fixedly connected to threaded parts inside the two T-shaped limiting slide grooves, and the two threaded parts are arranged in a mirror image.

[0010] Preferably, each of the two slide blocks is fixedly connected to a T-shaped slider at its lower end. The two T-shaped sliders are respectively inserted into the two T-shaped limiting slide grooves. The T-shaped sliders are provided with threaded through holes in the middle. The two sides of the rotating shaft pass through the threaded through holes in the middle of the two T-shaped sliders and the threaded part is threadedly connected to the T-shaped sliders.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) In this utility model, by setting a structure in which a U-shaped clamping seat cooperates with a linear guide rail, the strip reciprocating saw blade can be stably clamped and linear feed motion can be achieved, which solves the problem that the traditional circular saw blade grinding device cannot adapt to the shape and motion mode of the reciprocating saw blade, and significantly improves the grinding accuracy and stability of the reciprocating saw blade.

[0015] (2) In this utility model, a dual-motor driven symmetrically arranged grinding disc structure is adopted, which is combined with a synchronously adjustable sliding block mechanism. This can not only achieve synchronous grinding of the saw teeth on both sides of the reciprocating saw blade, but also flexibly adjust the grinding spacing to adapt to saw blades of different thicknesses, which greatly improves the versatility and grinding efficiency of the device.

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figure 1-4This utility model provides an embodiment of a highly stable reciprocating saw blade grinding device, comprising a support plate 1, a fixed seat 101 vertically fixedly connected to the middle of the upper end face of the support plate 1, a linear guide rail 102 fixedly connected to the middle of the upper end face of the fixed seat 101, a U-shaped clamp 2 connected to the front end of the upper end of the linear guide rail 102, clamping plates 202 provided on both sides of the middle of the upper end of the U-shaped clamp 2, and the lower end of the U-shaped clamp 2 connected to the linear guide rail 102 by a linear slider 201, with the inner end faces of the two clamping plates 202 fixed. A baffle plate 205 is fixedly connected to the front end face of the U-shaped clamp 2, and electro-hydraulic rods 204 are fixedly connected to the middle of both sides of the U-shaped clamp 2. The telescopic ends of the two electro-hydraulic rods 204 on both sides of the U-shaped clamp 2 extend into the U-shaped clamp 2 and are fixedly connected to the outer ends of the two clamping plates 202 respectively. The four electro-hydraulic rods 204 are connected by a synchronizer. The reciprocating saw blade to be sharpened is placed longitudinally in the middle of the U-shaped clamp 2, and the four electro-hydraulic rods 204 work synchronously to drive the two clamping plates 202 respectively. The clamping plates 202 move relative to each other, causing the two anti-slip plates 203 to fix and clamp the reciprocating saw blade on both sides, while the teeth of the reciprocating saw blade to be ground extend out of the upper end of the U-shaped clamping seat 2. The upper surface of the support plate 1 and the middle of both sides of the fixed seat 101 are fixedly connected to the adjusting seats 3. The upper end of each adjusting seat 3 is connected to the slide 4. The upper end of each slide 4 is fixedly connected to the inclined drive motor 401. The two drive motors 401 are mirrored and the output shafts of each are fixedly connected to the grinding disc 402. The grinding disc moves along the linear guide rail 102 through the U-shaped clamping seat 2. The blade slides backward, causing the upper teeth of the reciprocating saw blade to pass between the two grinding discs 402. The two drive motors 401 drive the two grinding discs 402 to rotate and grind both sides of the teeth of the reciprocating saw blade. By setting the two grinding discs 402 to rotate in the opposite direction to the movement of the U-shaped clamp 2, the force exerted by the grinding discs 402 on the reciprocating saw blade is directed towards the front end. The baffle plate 205 limits the front end of the reciprocating saw blade and cancels the forward friction force on the reciprocating saw blade, preventing the reciprocating saw blade from loosening between the two anti-slip plates 203.

[0024] Please see Figure 3 and Figure 4Both adjusting seats 3 have T-shaped limiting grooves 301 on their upper surfaces. A rotating shaft 302 is rotatably connected to the center of each T-shaped limiting groove 301. Threaded portions 303 are fixedly connected to both sides of the rotating shaft 302 within the two T-shaped limiting grooves 301, and the two threaded portions 303 are mirror-shaped. T-shaped sliders 5 are fixedly connected to the lower ends of both sliding seats 4. The two T-shaped sliders 5 are inserted into the two T-shaped limiting grooves 301. A threaded through hole 501 is provided in the center of each T-shaped slider 5. The rotating shaft 302 passes through the threaded through holes 501 in the center of each T-shaped slider 5, and the threaded portions 303 are threadedly connected to the T-shaped sliders 5. Lateral guides are fixedly connected to the front and rear ends of the center of each T-shaped limiting groove 301. The rod 304 and the T-shaped slider 5 are provided with guide holes 502 at both the front and rear ends of the middle. The two guide rods 304 pass through the two guide holes 502 on the T-shaped slider 5 respectively. The driving device 6 is fixedly connected to the middle of the outer side of the adjustment seat 3 on one side. The servo motor module 601 is fixedly installed inside the driving device 6. One end of the rotating shaft 302 extends into the driving device 6 and is fixedly connected to the output shaft of the servo motor module 601. The servo motor module 601 drives the rotating shaft 302 to rotate, so that the rotating shaft 302 synchronously drives the two T-shaped sliders 5 to move relative to each other, thereby causing the two slide seats 4 and the driving motor 401 on them to move relative to each other, so as to adjust the distance between the lower ends of the two grinding discs 402, which is convenient for grinding reciprocating saw blades of different thicknesses.

[0025] Please see Figure 3 When grinding a circular saw blade, the grinding disc 402 on one side drive motor 401 is removed and the circular saw blade with grinding is fixed. Then, the two slides 4 and the drive motors 401 on them move relative to each other, so that the grinding disc 402 on one side drive motor 401 and the circular saw blade on one side drive motor 401 move relative to each other, so that the lower ends of the grinding disc 402 and the circular saw blade come into contact. The two drive motors 401 rotate in opposite directions to grind the circular saw blade.

[0026] Working Principle: In use, the reciprocating saw blade to be ground is first placed longitudinally into the U-shaped clamp 2. The synchronously controlled electro-hydraulic rod 204 pushes the two clamping plates 202 to move towards each other, using the anti-slip plate 203 to firmly clamp the saw blade body, while simultaneously exposing the saw teeth above the clamp. Two drive motors 401 are activated, causing the grinding discs 402 to rotate in opposite directions. The servo motor module 601 drives the rotating shaft 302, causing the two T-shaped sliders 5 to move synchronously towards or away from each other along the T-shaped limiting groove 301, thereby precisely adjusting the distance between the two grinding discs 402 to accommodate different saw blade thicknesses. During grinding, the U-shaped clamp 2 slides smoothly backward along the linear guide rail 102 via the linear slider 201, and the saw teeth pass sequentially between the lower ends of the two rotating grinding discs 402 to complete synchronous grinding on both sides. During this process, the forward force exerted by the grinding discs 402 on the saw teeth is effectively counteracted by the stop plate 205, ensuring that the saw blade does not shift while clamped. When it is necessary to grind the circular saw blade, one side of the grinding disc 402 can be removed and the circular saw blade can be installed on the output shaft of the corresponding drive motor 401. By adjusting the position of the single-side grinding disc 402, single-sided grinding can be achieved.

[0027] It will be apparent to those skilled in the art that this invention 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 essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
