Description

Technical Field

[0001] The utility model relates to the technical field of metal material processing equipment, in particular to a burr grinding device. Background Art

[0002] During metalworking, burrs inevitably form on the edges of metal profiles. Deburring equipment can be used to remove burrs from profile edges. Deburring equipment typically includes a driving wheel and a driven wheel, both of which are grinding wheels. For example, when deburring a metal profile, the profile is passed between the driving and driven wheels, with both sides of the profile contacting the driving and driven wheels, respectively, thereby grinding away the burrs on the profile surface.

[0003] In existing burr removal equipment, the passive wheel is supported on the frame only by the wheel axle.

[0081] The present invention provides a burr removal device for removing burrs generated on the edges of profiles during the processing of profiles. The profiles described in this application are objects with a certain geometric shape made from materials with certain strength and toughness through processes such as rolling, extrusion, and casting. The burr removal device of this application is particularly suitable for removing burrs from plate-shaped metal profiles, but is not limited to plate-shaped metal profiles.

[0082] Now, refer to the attached Figure 1 To the attached Figure 8b Exemplary embodiments according to the present invention are described in more detail.

[0083] like Figures 1 to 3As shown, the burr grinding device 100 includes a workbench 110, which is provided with a driving wheel 10, a first driving device 20 and a passive wheel 30. The driving wheel 10 is used to grind the burrs on the first side of the profile, and the passive wheel 30 is used to grind the burrs on the second side of the profile. The rotation axis of the passive wheel 30 is arranged parallel to the rotation axis of the driving wheel 10. The first driving device 20 is used to drive the driving wheel 10 to rotate. As a result, the profile passes between the driving wheel 10 and the passive wheel 30, and the two sides of the profile are respectively polished by the driving wheel 10 and the passive wheel 30 to remove the burrs on the two sides. The workbench 110 is also provided with a supporting wheel 40, which is arranged on the side of the passive wheel 30 away from the driving wheel 10, and the rotation axis of the supporting wheel 40 is arranged parallel to the rotation axis of the passive wheel 30, and the supporting wheel 40 abuts against the passive wheel 30. The support wheel 40 is a circular wheel that can rotate around an axis and is arranged on the side of the driven wheel 30 perpendicular to its rotation axis, thereby supporting the driven wheel 30 in a direction perpendicular to the rotation axis and preventing the driven wheel 30 from tilting under the extrusion of the profile.

[0084] As will be appreciated, the deburring apparatus 100 is typically used to pass a profile between the driving wheel 10 and the driven wheel 30, whereupon both sides of the profile are respectively polished by the driving wheel 10 and the driven wheel 30 to remove burrs from the sides. While the driven wheel 30 polishes the profile, it rotates under the friction of the profile. Alternatively, only one side of the profile may be polished by either the driving wheel 10 or the driven wheel 30.

[0085] The first drive device 20, such as a motor, preferably a reduction motor, is configured to match the required rotational speed and transmission torque. The first drive device 20 and the driving wheel 10 are preferably secured to opposite sides of the workbench 110. For example, the driving wheel 10 is secured above the workbench, while the first drive device 20 is secured below the workbench. The output shaft of the first drive device 20 passes through the workbench 110 and connects to the driving wheel 10, thereby driving the driving wheel 10 to rotate.

[0086] The driving wheel 10 and the driven wheel 30 are both grinding wheels, which are arranged in a circular shape. When the profile to be ground is plate-shaped, the outer periphery of the driving wheel 10 and the driven wheel 30 is provided with a groove in the middle part along its axial direction, which surrounds a circle, and the cross-section of the groove is, for example, V-shaped. The plate-shaped profile has a thickness, and the two side edges of the V-shaped groove respectively contact the upper edge and the lower edge of the side of the plate-shaped profile to be processed to grind off the burrs on the upper edge and the lower edge of the side of the plate-shaped profile. The driving wheel 10 or the driven wheel 30 can be integrally formed, or can be composed of two grinding wheels fixedly connected. The two grinding wheels that constitute the driving wheel 10 or the driven wheel 30 are coaxially connected, and the grinding wheels are provided with chamfers on the side where they are connected, so that a V-shaped groove is formed at the connection between the two grinding wheels.

[0087] In some preferred embodiments, the burr grinding device 100 includes at least two support wheels 40, at least one of the at least two support wheels 40 is located on one side of the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located, and at least one of the at least two support wheels 40 is located on the other side of the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located, so that the support of the support wheels 40 on the driven wheel 30 is balanced. The rotation axis of the driving wheel 10 is parallel to the rotation axis of the driven wheel 30, and the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located is a plane defined by two parallel lines of the rotation axes of the driving wheel 10 and the driven wheel 30. More preferably, the at least two support wheels 40 are symmetrically arranged with respect to the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located.

[0088] like Figure 3 As shown, the burr grinding device 100 includes two support wheels 40, and the two support wheels 40 are respectively located on both sides of the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located. For another example, the burr grinding device 100 includes three support wheels 40, two of which are respectively located on both sides of the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located, and the rotation axis of the other support wheel 40 is located in the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located. For another example, the burr grinding device 100 includes four support wheels 40, two of which are coaxially arranged and located on one side of the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located, and the other two support wheels 40 are coaxially arranged and located on the other side of the plane where the rotation axes of the driving wheel 10 and the driven wheel 30 are located. Of course, the burr grinding device 100 may also include only one support wheel 40. Preferably, the rotation axis of the support wheel 40 is in the same plane as the rotation axes of the driven wheel 30 and the driving wheel 10. The supporting wheel 40 may also be a bearing, so that the outer ring surface of the bearing directly abuts against the driven wheel 30 .

[0089] The passive wheel 30 is set on the workbench 110 through the first bracket 31, and the passive wheel 30 is rotatably supported on the first bracket 31. For example, the passive wheel 30 is mounted on an axle, and the axle is supported on the first bracket 31 through a bearing so that the axle and the first bracket 31 can move relative to each other. The support wheel 40 is set on the workbench 110 through the second bracket 41, and the support wheel 40 is rotatably supported on the second bracket 41. Preferably, at least two support wheels 40 are set on the workbench 110 through the same second bracket 41. Figure 3 As shown, the two support wheels 40 are mounted on the workbench 110 by the same second bracket 41 .

[0090] The workbench 110 is also provided with a guide rail 60. The first bracket 31 and the second bracket 41 are movable along the guide rail 60 to adjust the distance between the driven pulley 30 and the driving pulley 10. The profile moves along a first direction D1, and the driving pulley 10 and the driven pulley 30 are arranged along a second direction D2. The guide rail 60 extends along the second direction D2. The first direction D1 is perpendicular to the second direction D2.

[0091] To enable the first bracket 31 to move along the guide rail 60, the guide rail 60 may optionally be provided with a guide groove, within which a slider is movable along the guide rail 60, and the slider is connected to the first bracket 31. The slider may be connected to the first bracket 31 via fasteners or may be integrally formed with the first bracket 31. Similarly, the second bracket 41 may be connected to another slider within the guide groove.

[0092] Further preferably, scale lines are provided above the guide rail 60 , and the scale lines are provided on the exposed surface and arranged along the second direction D2 , so as to intuitively display the adjustment distance of the passive wheel 30 , so as to facilitate the operator to perform visual adjustment.

[0093] To ensure that the supporting wheel 40 and the passive wheel 30 are always in close contact, in some specific embodiments, a tensile elastic member (e.g., a spring in a tensile state) is connected between the first bracket 31 and the second bracket 41, and the tensile elastic member is used to provide tension between the second bracket 41 and the first bracket 31. In other specific embodiments, the workbench 110 is further provided with a third bracket 50, which is located on the side of the second bracket 41 away from the first bracket 31 and is fixedly connected to the first bracket 31. A compression elastic member (e.g., a spring, rubber spring, etc. in a compressed state) is provided between the third bracket 50 and the second bracket 41, and the compression elastic member is used to provide thrust between the second bracket 41 and the third bracket 50. The third bracket 50 can be movable along the guide rail 60 together with the first bracket 31 to adjust the position of the passive wheel 30. The third bracket 50 can also be connected to a slider to move along the guide rail 60. It should be noted that the third bracket 50 and the first bracket 31 can be two components fixedly connected together, or they can be integrally formed components.

[0094] In the embodiment with the third bracket 50, when the supporting wheel 40 is separated from the driven wheel 30, in order to prevent the second bracket 41 from being separated from the third bracket 50 under the elastic force of the elastic member, a limiting device is provided between the third bracket 50 and the second bracket 41. Specifically, Figure 4As shown, a limiting rod 51, such as a screw, is connected between the third bracket 50 and the second bracket 41. The third bracket 50 is provided with a through hole. One end of the limiting rod 51 is fixedly connected to the second bracket 41, and the other end of the limiting rod 51 is connected to a limiting sleeve 52 (such as a nut) through the through hole of the third bracket 50. The limiting rod 51 can move axially within the through hole, and the radial dimension of the limiting sleeve 52 in the through hole is larger than the diameter of the through hole. Because the limiting sleeve 52 cannot pass through the through hole, the second bracket 41 can move within a certain range relative to the third bracket 50 without being separated from the third bracket 50.

[0095] The deburring apparatus 100 also includes an adjustment device 70 for adjusting the position of the passive wheel 30, specifically, the distance between the passive wheel 30 and the active wheel 10, to accommodate profiles of varying sizes. In some specific embodiments, the adjustment device 70 includes an adjustment sleeve 71 and an adjustment rod 72. The adjustment rod 72 extends along the guide rail 60. The adjustment sleeve 71 is secured to the workbench 110 and has a through hole with an internal thread. The adjustment rod 72 passes through the through hole of the adjustment sleeve 71 and is threadedly connected to the adjustment sleeve 71. One end of the adjustment rod 72 is connected to the first bracket 31. As the adjustment rod 72 rotates about its axis, it drives the first bracket 31 along the guide rail 60. The adjustment rod 72 can rotate relative to the first bracket 31 while maintaining its position relative to the first bracket 31. For example, the first bracket 31 may have a through hole through which the adjustment rod 72 passes, with stoppers positioned on either side of the through hole to prevent the rod from passing through. This allows the adjustment rod 72 to rotate relative to the first bracket 31 while maintaining its position relative to the first bracket 31.

[0096] It should be noted that in the embodiment where the third bracket 50 is provided, since the third bracket 50 is fixedly connected to or integrally formed with the first bracket 31 , the adjustment sleeve 71 or the adjustment rod 72 can also be connected to the first bracket 31 by being connected to the third bracket 50 .

[0097] The adjusting rod 72 of the adjusting device 70 is connected to a driving member 73, which drives the adjusting rod 72 to rotate around its own axis. Figure 5 As shown, the driving member 73 can be a hand wheel, which is in transmission connection with the adjusting rod 72. By rotating the hand wheel, the adjusting rod 72 is driven to rotate. In other specific embodiments, the driving member is connected to the driving shaft 74, and the driving shaft 74 is supported on the working platform through the bearing seat 75. The driving shaft 74 is connected to the adjusting rod 72 through a transmission mechanism. The transmission mechanism can be a sprocket transmission mechanism, a gear transmission mechanism, or a belt transmission mechanism, so that the operator can drive the adjusting rod 72 to rotate with less force. Figure 6As shown, the driving shaft 74 is connected to the first sprocket 76, and the adjusting rod 72 is connected to the second sprocket 77. The first sprocket 76 and the second sprocket 77 can be connected by a chain.

[0098] The adjustment device 70 may also include a locking mechanism 78, such as a shaft lock. The locking mechanism 78 is connected to the adjustment rod 72 or drive shaft 74 to prevent the adjustment rod 72 from rotating automatically. Specifically, the shaft lock can be a clamping structure, fixedly connected to the workbench 110 and fitted over the adjustment rod 72 or drive shaft 74. The clamping hole in the clamping mechanism, through which the adjustment rod 72 or drive shaft 74 passes, is a non-enclosed hole. Specifically, a notch is defined on the sidewall of the clamping mechanism, which communicates with the clamping hole. A fastener is connected to the notch to adjust the gap between the notches and thereby reduce the size of the clamping hole. When the fastener is tightened, the locker tightly abuts the adjustment rod 72 or drive shaft 74, clamping the adjustment rod 72 or drive shaft 74 to prevent the driven wheel 30 from shifting due to external impact during operation. When the spacing needs to be adjusted, the fastener is simply loosened to perform the adjustment. Of course, the locking mechanism 78 can also employ other structures to prevent the adjustment rod 72 from rotating.

[0099] In other specific embodiments, the adjustment sleeve 71 is fixedly connected to the first bracket 31, and the position of the adjustment rod 72 relative to the workbench 110 remains unchanged. Figure 7 As shown, the adjustment sleeve 71 is connected to the first bracket 31 by being connected to the third bracket 50. The adjustment sleeve 71 has a threaded hole, and the adjustment rod 72 is provided with an external thread. The adjustment rod 72 is screwed to the adjustment sleeve 71. The adjustment rod 72 is connected to the workbench 110 through a bearing, so that the adjustment sleeve 71 and the first bracket 31 are driven to move along the second direction D2 by rotating the adjustment rod 72.

[0100] The burr grinding device 100 also includes a guide device 80 for supporting and guiding the profile to facilitate the profile to pass between the driving wheel 10 and the driven wheel 30. The guide device 80 includes at least two guide rods 81, which extend along the first direction D1 and are located between the driving wheel 10 and the driven wheel 30. Preferably, at least some of the guide rods 81 are movable along the second direction D2 to accommodate profiles of different sizes. The driving wheel 10 and the driven wheel 30 are arranged along the second direction D2, and the first direction D1 is perpendicular to the second direction D2. The profile moves along the first direction D1 and passes between the driving wheel 10 and the driven wheel 30. The direction in which the rotation axes of the driving wheel 10 and the driven wheel 30 extend is the height direction D3. Preferably, the first direction D1 and the second direction D2 are perpendicular to the height direction D3. Of course, the first direction D1 and the second direction D2 may not be perpendicular to the height direction D3.

[0101] In some specific embodiments, the guide device 80 further includes a support rod 82 and a connector 83. The support rod 82 extends along the second direction D2, with its ends secured to the workbench 110 via respective mounting brackets. The connector 83 connects the guide rod 81 and the support rod 82, and the connector 83 is capable of sliding along the support rod 82, allowing the guide rod 81 to move along the second direction D2. This allows the spacing of the guide rods 81 to be adjusted to accommodate profiles of different sizes. For example, the guide device 80 includes two spaced support rods 82 and at least two guide rods 81, wherein each guide rod 81 is connected to two support rods 82 via two connectors 83.

[0102] The connecting member 83 is configured to have two connecting holes arranged in an upper and lower direction, and the upper connecting hole extends along the first direction D1, and the lower connecting hole extends along the second direction D2. The guide rod 81 and the support rod 82 are respectively installed in the upper and lower connecting holes. Preferably, a slot is provided on the side wall of the connecting hole to allow the support rod 82 or the guide rod 81 to be inserted into the connecting hole. At the same time, the profile can directly contact the guide rod 81 through the connecting member 83 without any protrusions, thereby ensuring that the profile passes smoothly. At the same time, a fastener, such as a screw, is provided on the connecting member 83. After passing through the side wall of the connecting hole, the fastener presses against the support rod 82 or the guide rod 81 to fix the support rod 82 or the guide rod 81 to the connecting member 83.

[0103] In other specific embodiments, the guide rod 81 can be directly fixed to the workbench 110 through the support frame 85. The connection between the support frame 85 and the guide rod 81 can be basically the same as the connection between the connecting member 83 and the guide rod 81, that is, the support frame 85 is provided with a connecting hole, and the guide rod 81 is inserted into the connecting hole.

[0104] More preferably, Figure 5 As shown, guide rods 81 are arranged at intervals along the rotation axis, for example, in two layers. That is, when the rotation axis of the driving wheel 10 is in the vertical direction, guide rods 81 are provided on both the upper and lower sides of the profile. This makes the profile more stable during movement, especially when the profile being polished is plate-shaped. There is at least one upper guide rod 81a, which can be directly fixed to the workbench 110 or the first bracket 31 via a support bracket 85. The upper guide rod 81a is fixed to the first bracket 31 via the support bracket 85.

[0105] The guide rod 81 is provided with a wear-resistant layer on its outer surface to increase its surface hardness and thereby extend its service life. This wear-resistant layer may be a cold-work hardened layer. Alternatively, the wear-resistant layer may be a metal coating, such as chromium, nickel, cobalt, or other metals. Other heat treatment methods, such as nitriding, may also be employed. The guide rod 81 may be directly formed from a piston rod.

[0106] The guide device 80 also includes at least one stopper plate 84, extending along the first direction D1 and aligned tangentially with the driving wheel 10 or the driven wheel. The stopper plate 84 is connected to the workbench 110 of the frame 90 or to the first bracket 31. Preferably, two stopper plates 84 are provided, one on each side of the guide rod 81. Their dimension in the height direction D3 is slightly larger than the profile's height dimension to prevent tilting.
