The existing centerless grinding machine generally comprises a grinding machine body, a grinding wheel 10, a guide wheel 20, a supporting plate 31 and the like, wherein the grinding wheel 10 and the guide wheel 20 are arranged in parallel, and the supporting plate 31 is positioned between the grinding wheel 10 and the guide wheel 20. In specific work, the supporting plate 31 supports the rod-like workpiece, the grinding wheel 10 rotates at a high speed to grind, and meanwhile, the guide wheel 20 rotates at a slower speed in the same direction to drive the workpiece to rotate for circumferential feeding, so that grinding processing of the surface of the rod-like workpiece is realized.
However, in the existing wide grinding machine dressing mode, the grinding wheel and the guide wheel are respectively dressed through the independent dressing devices, and each dressing device is controlled to move by the independent driving part, so that after long-term use, the moving direction of each dressing device has deviation, namely the paths are not parallel, and the moving paths of each dressing device are inconsistent with the grinding paths of the workpiece, so that the dressing does not reach the standard, the circle run-out of the workpiece after grinding is difficult to control in a smaller range, and the product quality is affected. In addition, the existing trimmer on the centerless grinder trims at the rear of the grinding wheel or the guide wheel, and the trimmer can trim only after stopping during trimming, so that the output is affected.
In a first aspect, referring to fig. 1 to 4, an embodiment of the present invention provides a trimming device, which includes a support base 100, and a first trimming assembly 200 and a second trimming assembly 300 disposed on the support base 100.
The support base 100 is configured to be disposed on the supporting frame 30 and move relative to the grinding machine body along a first direction, which is parallel to the rotation axis of the grinding wheel 10 or the guide wheel 20.
The grinding wheel 10 is moved to the outer circumference in contact with a portion of the first dressing assembly 200, and the grinding wheel 10 is driven to rotate for dressing.
And/or, moving the guide wheel 20 to the outer circumference to contact with a part of the second dressing assembly 300, and driving the guide wheel 20 to rotate for dressing.
The support base 100 in this embodiment is used for mounting the first trimming assembly 200 and the second trimming assembly 300, and may be a support plate, a support block, a support frame, etc., which may be fixedly connected to one side of the pallet 30 by screwing, welding, clamping, etc. The support 100 is movable with the carrier 30 in a first direction parallel to the axis of rotation of the grinding wheel 10 or the guide wheel 20, i.e. along the grinding path of the workpiece.
The first dressing assembly 200 and the second dressing assembly 300 in this embodiment are respectively used for dressing the grinding wheel 10 and the guide wheel 20, and may have the same structure, and the first dressing assembly 200 and the second dressing assembly 300 may be fixedly connected to the support base 100 by screwing, clamping, welding, or the like.
Specifically, as shown in fig. 1 and 2, dressing is performed when the grinding wheel 10 is moved in the second direction to the point where the outer circumference is in contact with a part of the first dressing assembly 200 and the grinding wheel 10 is driven to rotate. Or when the guide wheel 20 is moved in the second direction to the outer circumference to be in contact with a part of the second dressing assembly 300 and the guide wheel 20 is driven to rotate for dressing. The second direction is perpendicular to the first direction, and the second direction is distributed along the direction approaching or separating from the trimming device.
In this way, the two trimming assemblies are jointly arranged on the supporting seat, so that the movement of the supporting seat is consistent with the grinding path, namely, the movement paths of the two trimming assemblies and the supporting plate frame 30 are unique, the parallelism error caused by non-uniform paths of the two trimming assemblies and the supporting plate frame 30 in the prior art is eliminated, when the two trimming assemblies trim the grinding wheel 10 or the guide wheel 20 respectively, the cylindricity of the grinding wheel 10 is ensured to be consistent with that of the guide wheel 20, the circle runout of a workpiece after grinding is controlled within a smaller range, the grinding quality of a product is improved, the trimming operation is convenient, and the trimming efficiency is higher.
In some embodiments, the upper end of the support 100 is provided with a first arm 110 and a second arm 120 at intervals along the second direction, where the first arm 110 is located on a side close to the grinding wheel 10, and the second arm 120 is located on a side close to the guide wheel 20.
The first conditioning assembly 200 is attached to the first arm 110 and the second conditioning assembly 300 is attached to the second arm 120.
Specifically, as shown in fig. 1 and 2, the upper end of the supporting seat 100 is provided with a first support arm 110 and a second support arm 120 which are arranged at intervals along the second direction, that is, a space is formed between the first support arm 110 and the second support arm 120, the first support arm 110 and the second support arm 120 and the supporting seat 100 can form a U-shaped structure, the first support arm 110 and the second support arm 120 are both arranged along the vertical direction, and the lower ends of the first support arm 110 and the second support arm 120 can be integrally formed with the supporting seat 100 or fixedly connected with the supporting seat 100 by means of screw connection, welding and the like.
The first arm 110 is located at a side near the grinding wheel 10, the first dressing assembly 200 may be mounted on the first arm 110 and away from the second arm 120 by screwing, welding, etc., and the second dressing assembly 300 may also be mounted on the second arm 120 and away from the first arm 110 by screwing, welding, etc.
However, since the first dressing assembly 200 or the second dressing assembly 300 is in contact with the uneven surface of the grinding wheel 10 or the guide wheel 20 to form strong vibration during the dressing process, the first support arm 110 and the second support arm 120 can form a cantilever structure, and the vibration during the dressing process can be effectively absorbed, thereby improving the dressing accuracy.
Further, in the present embodiment, the first dressing assembly 200 and the second dressing assembly 300 each have a dressing portion 201 thereon, the dressing portion 201 is configured to contact with an outer circumference of the grinding wheel 10 or the guide wheel 20, and a projection of the dressing portion 201 along the second direction is offset from the support base 100.
Specifically, as shown in fig. 1 and 2, the upper sides of the first dressing assembly 200 and the second dressing assembly 300 are respectively provided with a dressing portion 201, the dressing portion 201 is a super wear-resistant tip, and the dressing portion 201 faces the adjacent grinding wheel 10 or the guide wheel 20 respectively and is directed to the surface of the grinding wheel 10 or the guide wheel 20 in a substantially radial direction.
It should be noted that the projection of the trimming portion 201 along the second direction is offset from the supporting seat 100, that is, the projection of the trimming portion 201 along the second direction is located on the first arm 110 or the second arm 120. Or the projection of the trimming portion 201 along the second direction exceeds the adjacent first arm 110 or second arm 120, but does not fall onto the support 100.
In this way, the force acting on the dressing portion 201 is transmitted in the second direction without falling on the support base 100, so that the vibration during the dressing process is effectively damped. The specific position of the trimming portion 201 may be determined according to the actual requirement, and is not excessively limited in the present embodiment.
Still further, in the present embodiment, at least one of the first arm 110 and the second arm 120 is provided with a buffer slot 111, and the buffer slot 111 is located at a side facing away from the corresponding trimming portion 201.

In this way, when the trimming portion 201 is vibrated by being pressed relatively much in the second direction, on the one hand, the positions of the first arm 110 and the second arm 120 near the root portions can be deformed in the direction away from the corresponding trimming portion 201, thereby further playing a role in damping vibration, and on the other hand, the deformation amounts of the root portions of the first arm 110 and the second arm 120 are limited by the limitation of the pitch of the damping grooves 111, so that the excessive deformation is avoided.
Preferably, the buffer grooves 111 are arranged at intervals in the vertical direction, and the cross section of the first arm 110 or the second arm 120 corresponding to each buffer groove 111 is sequentially reduced from bottom to top. In this way, the deformation of the root of the first arm 110 or the second arm 120 from bottom to top can be further effectively limited, so as to avoid excessive deformation.
It should be noted that the vertical spacing of the buffer slots 111 may be determined according to practical requirements, and the specific spacing in fig. 3 is only for illustration, and the specific spacing may be determined according to the deformation amount of the root portion of the first arm 110 or the second arm 120 and the number of the buffer slots 111. Also, the groove bottom of the buffer groove 111 may be provided in a circular shape to reduce stress concentration. In addition, the buffer slot 111 should be located below the fastening position of the first conditioning assembly 200 on the first arm 110, or the buffer slot 111 should be located below the fastening position of the second conditioning assembly 300 on the second arm 120.
