Description

Technical Field

[0001] This utility model belongs to the field of processing equipment technology, and specifically relates to an improved chamfering machine. Background Technology

[0002] Chamfering machines are mainly used for chamfering workpieces. A relatively simple type of chamfering machine on the market typically includes a worktable with a first guide plate and a second guide plate arranged in an L-shape or a V-shape. A chamfering cutter and a cutter drive mechanism for rotating the chamfering cutter are positioned on the worktable between the first and second guide plates.

[0003] For example, the Chinese utility model patent with publication number "CN218396269U" submitted by the applicant to the State Intellectual Property Office discloses a chamfering machine with two-axis adjustable worktable. The machine includes a worktable with a first guide plate and a second guide plate for guiding the workpiece. A cutter hole is formed between the first and second guide plates. It also includes a cutter head and a cutter head driving mechanism corresponding to the cutter hole. The first and second guide plates are mounted on a support block. A support plate is provided on the worktable, movable vertically. The support block is mounted on the support plate in a manner that allows horizontal movement relative to the cutter head. The machine also includes a first driving mechanism for moving the support block and a second driving mechanism for moving the support plate. By adopting the technical solution of this utility model, the first and second driving mechanisms enable two-axis adjustment of the first and second guide plates in both horizontal and vertical directions. This allows adjustment of the position of the workpiece to be ground and the cutter head. During use, the workpiece moves along the first and second guide plates, causing the cutter head to contact the workpiece, thus achieving chamfering. This fully utilizes the cutter head and reduces production costs.

[0004] Although the above-mentioned chamfering machine can adjust the position of the workpiece to be ground and the cutting head to make full use of the cutting head, the applicant found that the workpiece needs to move back and forth along the first guide plate and the second guide plate during grinding. This will easily cause wear on the contact surface between the workpiece and the two guide plates, thereby scratching or even damaging the workpiece, resulting in defective products.

[0005] In view of this, the applicant conducted in-depth research on the above-mentioned issues, which led to the occurrence of this case. Summary of the Invention

[0006] The purpose of this utility model is to provide an improved chamfering machine with a simple structure that does not easily cause wear to the workpiece during grinding.

[0007] To achieve the above objectives, this utility model adopts the following technical solution:

[0008] An improved chamfering machine includes a worktable with a first guide plate and a second guide plate for guiding workpieces. A grinding head for grinding the workpiece is positioned on the worktable between the first and second guide plates. A grinding head driving mechanism for rotating the grinding head is also provided at the bottom of the worktable. A sliding lateral movement mechanism for moving the first and second guide plates laterally is also provided on the worktable. The sliding lateral movement mechanism includes several fixed seats fixed to the worktable and sliding rods slidably passing through the fixed seats. Fixed plates are respectively provided at both ends of the worktable corresponding to the length directions of the first and second guide plates. The two ends of the first and second guide plates are respectively fixedly connected to the corresponding fixed plates, and the two ends of the sliding rods are respectively fixed to the corresponding fixed plates.

[0009] Furthermore, the first guide plate is arranged horizontally, the second guide plate is arranged vertically, and the first guide plate and the second guide plate are arranged in an L-shape.

[0010] Furthermore, the fixed base includes a first base and a second base spaced apart along the width direction of the workbench. The first base is located below the first guide plate, and both the first base and the second base have through holes in their middle portions for the sliding rod to pass through.

[0011] Furthermore, the workbench is provided with an installation slot corresponding to the position of the first base, the first base is embedded in the installation slot on the workbench, and the bottom of the installation slot is provided with a support plate for supporting the first base, the support plate being fixed to the bottom of the workbench.

[0012] Furthermore, rubber stop blocks for blocking the fixed plate are provided on both sides of the workbench. The rubber stop blocks on both sides are respectively arranged facing the corresponding fixed plate, and the rubber stop blocks are fixed on the workbench by stop block mounting seats.

[0013] Furthermore, a connecting plate is provided between the two fixed plates. The connecting plate is located above the workbench. The workbench is provided with a screw abutting mechanism for abutting the connecting plate. The connecting plate is provided with a plurality of grooves on one side corresponding to the screw abutting mechanism for the screws on the screw abutting mechanism to extend into.

[0014] Furthermore, each of the two fixed plates is provided with a first screw adjustment assembly for adjusting the height of the first guide plate at the position corresponding to the first guide plate, and each of the two fixed plates is provided with a second screw adjustment assembly for adjusting the horizontal position of the second guide plate at the position corresponding to the second guide plate.

[0015] Furthermore, the first screw adjustment assembly includes a slide block and a slider fixed to the bottom of the first guide plate. The slide block has a groove for the slider to move. The groove is arranged vertically. The side of the slider away from the slide block is fixedly connected to the fixed plate. The bottom of the slide block has a screw mounting seat and an adjusting screw passing through the screw mounting seat. The screw mounting seat has a first threaded hole through which the adjusting screw passes, corresponding to the position of the groove. The rod of the adjusting screw extends from the bottom of the threaded hole and abuts against the bottom of the slider.

[0016] Furthermore, one side of the slide block is provided with a limiting screw for limiting the relative movement of the slide block and the slider. The slide block is provided with a second threaded hole for the limiting screw to extend into, corresponding to the position of the limiting screw. A long groove is provided on the slide block corresponding to the position of the second threaded hole. The long groove is located near the side wall of the groove, and the arrangement direction of the long groove is the same as the arrangement direction of the groove. The second threaded hole is connected to the long groove.

[0017] Furthermore, the second guide plate is detachably provided with a limiting block for restricting the movement of the workpiece.

[0018] By adopting the aforementioned design scheme, the beneficial effects of this utility model are:

[0019] This improved chamfering machine features a sliding transverse mechanism on the worktable. The fixed plates on both sides drive the first and second guide plates to move synchronously, allowing them to move closer to or further away from the cutting head. Compared to existing technologies, the synchronous movement of the workpiece with the first and second guide plates effectively prevents wear on the contact surfaces, thus avoiding scratches or damage and significantly improving the yield rate.

[0020] Furthermore, a mounting slot is provided on the workbench corresponding to the position of the first base. The first base is embedded in the mounting slot on the workbench. A support plate for supporting the first base is provided at the bottom of the mounting slot. This arrangement can reduce the height of the first base, leaving space for the first guide plate to adjust its height, thereby preventing the first guide plate from colliding with the first base when adjusting its height.

[0021] Furthermore, rubber stop blocks are provided on both sides of the worktable to block the fixed plate. With this design, when the sliding transverse mechanism moves the first guide plate and the second guide plate left and right and approaches the worktable, the rubber stop blocks can provide a buffering effect, which can prevent the fixed plate from directly hitting the worktable and causing damage, thus extending the service life of the chamfering machine.

[0022] Furthermore, the workbench is equipped with a screw abutting mechanism for abutting the connecting plate. The connecting plate has several grooves on one side corresponding to the screw abutting mechanism for the screws on the screw abutting mechanism to extend into. With this configuration, when the sliding transverse mechanism is not needed, the connecting plate can be fixed by extending the screws on the screw abutting mechanism into the grooves, thus preventing the sliding transverse mechanism from sliding left and right.

[0046] 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.

[0047] like Figures 1 to 4 As shown, an improved chamfering machine includes a worktable 1, which is a rectangular plate and horizontally positioned. Support legs 10 are provided around the worktable 1 for support. A first guide plate 11 and a second guide plate 12 are provided on the worktable 1 for guiding the workpiece. The length direction of the first guide plate 11 and the second guide plate 12 is the same as the length direction of the worktable 1. A grinding head 13 is provided on the worktable 1 at a position corresponding to the gap between the first guide plate 11 and the second guide plate 12 for grinding the workpiece. The grinding head 13 is located at the second guide plate 11. The guide plate 12 is located away from the first guide plate 11. Correspondingly, the bottom of the worktable 1 is also provided with a cutter head drive mechanism 14 for driving the cutter head 13 to rotate. It should be noted that the cutter head 13 and the cutter head drive mechanism 14 can adopt conventional structures in the art. Specifically, in this utility model, the cutter head drive mechanism 14 is a motor, the cutter head 13 is mounted on the spindle (not shown in the figure), the cutter head 13 is provided with a blade, the spindle is rotatably mounted on the worktable 1 in the vertical direction, and the spindle is connected to the motor for transmission, for example, by belt transmission.

[0048] like Figure 1As shown, with the length direction of the first guide plate 11 as the left-right direction and the width direction of the first guide plate 11 as the front-back direction, the worktable 1 is also provided with a sliding transverse mechanism 2 for driving the first guide plate 11 and the second guide plate 12 to move laterally in the left-right direction. In this embodiment, the sliding transverse mechanism 2 includes several fixed seats 21 fixed on the worktable 1 and sliding rods 22 slidably passing through the fixed seats 21. The worktable 1 is provided with fixed plates 23 at both ends of the length direction corresponding to the first guide plate 11 and the second guide plate 12, and the two ends of the length direction of the first guide plate 11 and the second guide plate 12 are respectively fixedly connected to the corresponding fixed plates 23. The two ends of the sliding rods 22 are respectively fixed on the corresponding fixed plates 23. The fixed seats 21 include first guide plates 23 that are spaced apart along the width direction of the worktable 1. The base 211 and the second base 212 are provided, and correspondingly, two sliding rods 22 are provided. The two sliding rods 22 are respectively passed through the first base 211 and the second base 212. The first base 211 is located below the first guide plate 11. The middle part of the first base 211 and the second base 212 are provided with through holes for passing through the sliding rods 22. The number of the first base 211 and the second base 212 can be set according to actual needs. Preferably, in this embodiment, there are two first bases 211 and two bases 212, and the first bases 211 and the second bases 212 have the same structure. The two first bases 211 are spaced apart along the length direction of the worktable 1, and the two second bases 212 are spaced apart along the length direction of the worktable 1, so as to achieve a better support effect.

[0049] This improved chamfering machine features a sliding transverse mechanism 2 on the worktable 1, with fixed plates 23 on both sides driving the first guide plate 11 and the second guide plate 12 to move synchronously. This allows the first guide plate 11 and the second guide plate 12 to move closer to or further away from the cutter head 13. In use, the operator first places the workpiece against the first guide plate 11 and the second guide plate 12, and then pulls the first guide plate 11, the second guide plate 12, or the fixed plate 23. This allows the sliding transverse mechanism 2 to drive the first guide plate 11, the second guide plate 12, and the workpiece to move synchronously closer to the cutter head 13 for grinding. Compared to existing technologies, the synchronous movement of the workpiece with the first guide plate 11 and the second guide plate 12 effectively avoids wear on the contact surfaces of the workpiece and the first guide plate 11 and the second guide plate 12, preventing scratches or damage to the workpiece and thus effectively improving the yield rate.

[0050] Preferably, the first guide plate 11 is arranged horizontally and the second guide plate 12 is arranged vertically, with the first guide plate 11 and the second guide plate 12 arranged in an L-shape.

[0051] Preferably, each of the two fixing plates 23 is provided with a first screw adjustment assembly 3 for adjusting the height of the first guide plate 11 at a position corresponding to the first guide plate 11. The two first screw adjustment assemblies 3 are symmetrically arranged with the middle of the first guide plate as the center. Similarly, each of the two fixing plates 23 is provided with a second screw adjustment assembly 4 for adjusting the horizontal position of the second guide plate 12 at a position corresponding to the second guide plate 12. The two second screw adjustment assemblies 4 are symmetrically arranged with the middle of the second guide plate as the center. Since the height of the cutter head 13 and the height of the first guide plate 11 are both factory-preset, their heights are compatible. Furthermore, since the first base 211 is located below the first guide plate 11, to avoid the first guide plate 11 colliding with the first base 211 when adjusting its height, preferably, as shown... Figure 3 As shown, in this utility model, a mounting slot 16 is provided on the workbench 1 at the position corresponding to the first base 211. The first base 211 is embedded in the mounting slot 16 on the workbench 1. A support plate 17 for supporting the first base 211 is provided at the bottom of the mounting slot 16. The middle part of the support plate 17 is used to support the first base 211. The support plate 17 is fixed to the bottom of the workbench 1 by fasteners. This arrangement can reduce the height of the first base 211, leaving space for the first guide plate 11 to adjust its height, thereby avoiding the first guide plate 11 from bumping into the first base 211 when adjusting its height.

[0052] like Figure 3 and Figure 4 As shown ( Figure 4 (The perspective in the image is from below). The first screw adjustment assembly 3 includes a slide block 31 and a slider 32 fixed to the bottom of the first guide plate 11. The slide block 31 has a groove 33 for the slider 32 to move. The groove 33 is arranged vertically. The side of the slider 32 away from the slide block 31 is fixedly connected to the fixing plate 23. The bottom of the slide block 31 has a screw mounting seat 34 and an adjusting screw 35 passing through the screw mounting seat 34. The screw mounting seat 34 has a first threaded hole 36 through which the adjusting screw 35 passes, corresponding to the position of the groove 33. The rod of the adjusting screw 35 extends from the bottom of the first threaded hole 36 and abuts against the bottom of the slider 32. With this configuration, the relative position of the slider 32 and the slide block 31 can be adjusted by tightening or loosening the adjusting screw 35. Since the slider 32 is fixedly connected to the fixed plate 23, and the fixed plate 23 is fixed to the worktable 1 by the sliding rod 22 and the fixed seat 21, it cannot move up and down. Therefore, when the adjusting screw 35 is tightened or loosened, the slide block 31 can move relative to the slider 32, thereby driving the first guide plate 11 to move up and down to adjust the height.

[0053] Preferably, the first screw adjusting assembly 3 further includes a limiting screw 37 disposed on the front side of the slide 31 to limit the relative movement of the slide 31 and the slider 32. The slide 31 has a second threaded hole 311 corresponding to the position of the limiting screw 37, into which the limiting screw 37 extends. Specifically, an elongated groove 312 is formed on the slide 31 corresponding to the position of the second threaded hole 311. The elongated groove 312 is located near the side wall of the slide groove 33, and its arrangement direction is the same as that of the slide groove 33. The second threaded hole 311 communicates with the elongated groove 312. When the limiting screw 37 is tightened, the shaft of the limiting screw 37 extends from the second threaded hole 311 into the elongated groove 312. Due to the elongated groove 312, tightening the limiting screw 37 can apply pressure to the side wall of the slide groove 33 corresponding to the elongated groove 312. This causes the sidewall to press tightly into the slide groove 33, thereby pressing the slider 32 within the slide groove 33 and limiting the relative movement of the slide block 31 and the slider 32. The second screw adjustment assembly 4 is located on the rear side of the second guide plate 12. It should be noted that the second screw adjustment assembly 4 and the first screw adjustment assembly 3 have the same structure, the only difference being the orientation. The first screw adjustment assembly 3 is arranged vertically, while the second screw adjustment assembly 4 is arranged front and back. The front and back position of the second guide plate 12 can be adjusted by the second screw adjustment assembly 4. By setting the first screw adjustment assembly 3 to adjust the height of the first guide plate 11 and setting the second screw adjustment assembly 4 to adjust the front and back position of the second guide plate 12, the distance between the first guide plate 11 and the second guide plate 12 can be adjusted, thereby adjusting the grinding position according to different workpieces.

[0054] Preferably, the second guide plate 12 is detachably provided with a limiting block 121 for restricting the movement of the workpiece. The detachment method can be any conventional method in the art, such as disassembly by fasteners. In use, the workpiece is placed on the first guide plate 11, the second guide plate 12 and the limiting block 121, and then the workpiece is pressed down by hand so that the other side of the workpiece abuts against the limiting block 121 to ensure the stability of the workpiece during processing.

[0055] Preferably, rubber stop blocks 18 for blocking the fixed plate 23 are provided on both sides of the worktable 1. The rubber stop blocks 18 on both sides are respectively arranged facing the corresponding fixed plate 23. The rubber stop blocks 18 are fixed on the worktable 1 by the stop block mounting seat 19, and the rubber stop blocks 18 on both sides protrude from the outer side of the worktable 1. With this arrangement, when the sliding transverse mechanism 2 drives the first guide plate 11 and the second guide plate 12 to move left and right and approach the worktable 1, the rubber stop blocks 18 can play a buffering role, which can prevent the fixed plate 23 from directly hitting the worktable 1 and causing damage, thus extending the service life of the chamfering machine.

[0056] Preferred, such as Figure 2As shown, a connecting plate 24 is also provided between the two fixed plates 23. The connecting plate 24 is located above the workbench 1 and behind the second guide plate 12. The workbench 1 is provided with a screw abutting mechanism 20 for abutting the connecting plate 24. The screw abutting mechanism 20 includes a base 201 fixed on the workbench 1 and abutting screw 202 passing through the base 201. Correspondingly, the connecting plate 24 is provided with a plurality of grooves 241 on the side corresponding to the abutting screw 202 for the abutting screw 202 to extend into. When the sliding transverse mechanism 2 is not needed, the connecting plate 24 can be fixed by extending the abutting screw 202 into the groove 241 to prevent the sliding transverse mechanism 2 from sliding left and right.

[0057] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
