As shown in fig. 1 and 2, the double-wheel slot milling machine of the present embodiment includes a milling cutter holder 4, a milling cutter 6 provided at the bottom of the milling cutter holder 4, and a deviation correcting device provided on the side surface of the milling cutter holder 4. The double-wheel slot milling machine is positioned in the slot wall 5.
As shown in fig. 3, when the milling cutter holder 4 is tilted in the slot wall, the push plates of the deviation rectifying devices located at the lower left corner and the upper right corner are respectively pushed out in the direction of the arrow (the pushing direction is perpendicular to the side plate of the milling cutter holder) under the action of the respective cylinders until the push plates abut against the slot wall, and at this time, the slot wall generates a reaction force to the push plates. Along with the continuous push-out of the oil cylinder and the push plate, the counter-acting force of the groove wall on the push plate of the deviation correcting device can enable the milling cutter frame 4 to rotate anticlockwise until the milling cutter frame 4 is in a vertical state.
The milling cutter holder 4 of the double-wheel slot milling machine of the embodiment is of a square structure and comprises four side surfaces which are circumferentially enclosed. The four sides include two first sides parallel to the axis of the cutterhead 6 and two second sides perpendicular to the axis of the cutterhead 6. The first side surface is provided with a first deviation correcting device 1, and the second side surface is provided with a second deviation correcting device 2. As shown in fig. 4, a first rock wall projection 51 is formed on a first groove wall parallel to the axis of the cutterhead 6, and a second rock wall projection 52 is formed on a second groove wall perpendicular to the axis of the cutterhead 6. The two second deviation rectifying devices 2 on the same side of the milling cutter holder 4 are respectively located on two sides of the second rock wall bulge 52, and in operation, the second deviation rectifying devices 2 and the second rock wall bulge 52 are spaced from each other, so that the second rock wall bulge 52 has no influence on the action of the second deviation rectifying device 2. However, the first rock wall projection 51 is located in the middle of the first deviation rectification device 1, so that the first rock wall projection 51 may have an adverse effect on the deviation rectification of the first deviation rectification device 1.
In order to improve the above problem, as shown in fig. 5 to 7, the embodiment of the present invention provides an improvement to the first deviation correcting device 1, where the first deviation correcting device 1 includes a push plate 12, and the push plate 12 is provided with an avoiding groove 124 penetrating in the longitudinal direction X.
When the first deviation correcting device 1 of the embodiment of the present invention works, referring to fig. 4, the first rock wall protrusion 51 on the groove wall 5 enters the avoiding groove 124 to prevent the pushing plate 12 of the first deviation correcting device 1 from extruding with the first rock wall protrusion 51, so as to avoid the influence on the deviation correcting stability and the grooving precision. In addition, the push plate 12 of the embodiment avoids the protrusion of the rock wall, and simultaneously, the contact between the plane of the push plate and the rock wall is changed from point contact into double parallel line contact, so that the deviation rectification stability is improved.
In the present embodiment, as shown in fig. 6, the pushing plate 12 includes a bottom plate 121 and a top plate located above the bottom plate 121, and the top plate is provided with an avoiding groove 124.
The bottom plate 121 and the top plate of the present embodiment are separately provided, and the top plate being located above the bottom plate 121 means that the top plate of the present embodiment is stacked above the bottom plate 121 in the thickness direction. And the top plate of the present embodiment is connected to the bottom plate 121 by the connecting means 123. The connecting device 123 may be a detachable structure or a non-detachable structure.
However, in other embodiments not shown in the drawings, the bottom plate and the top plate are integrally provided to form the push plate, and in this case, there is no division between the bottom plate and the top plate in the thickness direction of the push plate. The upper side of the push plate in the thickness direction is directly provided with an avoiding groove. The integrally provided push plate can be manufactured, for example, by forging or the like.
In some embodiments, the top plate includes two partial top plates 122 respectively located at both sides of the escape slot 124, and a gap between the two partial top plates 122 forms the escape slot 124. Specifically, in the present embodiment, as shown in fig. 6, the two partial ceiling plates 122 are independently provided. And the two sub-ceiling plates 122 are respectively connected to both lateral sides of the bottom plate 121 by connection means 123. In this case, the escape groove 124 directly penetrates the top plate in the thickness direction of the top plate.
In other embodiments, the top plate may also include more than three independent sub-plates, as long as the avoidance groove can be constructed, and the number of the sub-plates is not limited.
In other embodiments not shown in the figures, the two partial ceiling panels are provided integrally. The two sub-top plates are integrated and connected with each other. For example, a slot is made directly in the middle of the top plate. The avoiding groove can penetrate in the thickness direction of the top plate or can not penetrate in the thickness direction of the top plate. The avoidance groove is formed in the first rock wall, and the width and the depth of the avoidance groove are larger than those of the first rock wall protrusion, so that the avoidance effect is achieved.
The avoidance groove 124 of the present embodiment is configured to receive the first rock wall projection 51 for the avoidance effect. In the present embodiment, the width and depth of the avoiding groove 124 are larger than the height and width of the first rock wall protrusion 51, so as to achieve the avoiding effect.
The sidewall of the escape groove 124 of the present embodiment is formed by the side surfaces of the ceiling dividing plates 122 disposed at both sides. In the present embodiment, the side surface of the ceiling-divided plate 122 is disposed obliquely with respect to the upper surface of the ceiling-divided plate 122. Specifically, the side surface of the ceiling portion 122 and the upper surface of the ceiling portion 122 form an obtuse angle therebetween.
As shown in fig. 6, the relief groove 124 of the present embodiment includes a flared section 1241 at a longitudinally lower end. When the first deviation correcting device 1 works, the first rock wall protrusion 51 enters the avoiding groove 124 from the flaring section 1241, the flaring section 1241 is arranged to be beneficial to ensuring that the first rock wall protrusion 51 smoothly enters the groove, and the first rock wall protrusion 51 is prevented from being clamped by the avoiding groove 124.
The relief groove 124 of this embodiment also includes a flared section at the upper longitudinal end. The upper and lower symmetry of the deviation correcting device of the embodiment is realized by the arrangement, and the deviation correcting device is not required to be distinguished during installation so as to improve the efficiency.
As shown in fig. 7, the upper surface of the ceiling dividing plate 122 of the present embodiment includes inclined sections 1221 at the longitudinal ends. The inclined section 1221 can reduce the shearing force applied to the branch top plate 122 and the connecting device 123 in the milling process, and prevent the branch top plate 122 and the connecting device 123 from being damaged.
Preferably, the plane section 1222 of the upper surface of the ceiling-dividing plate 122 is smoothly connected with the inclined section 1221 so that the inclined section 1221 is streamlined.
The deviation correcting device of the embodiment further comprises a deviation correcting main body 11 arranged on the lower side of the push plate 12. The base plate 121 is rotatably connected to the correcting body 11. The upper end of the bottom plate 121 of this embodiment is bent toward the deviation rectifying body 11 to cover the space between the bottom plate 121 and the deviation rectifying body 11. During the operating condition, should bend and can prevent to mill the in-process upper portion and drop the stone and produce the extrusion to deviation correcting device inner structure. In the embodiment, the deviation rectifying main body 11 includes a base and a plurality of internal structures, such as a four-bar linkage, an oil cylinder, etc., disposed between the bottom plate 121 and the base. Therefore, the upper end of the bottom plate 121 of the present embodiment is bent to protect the internal structures.
Preferably, the lower end of the bottom plate 121 of the present embodiment is also provided with a bend. The second deviation correcting device 2 may have the same structure as the first deviation correcting device 1 of the above embodiment. However, since the second rock wall projection 52 does not affect the operation of the second deviation correction device 2, the push plate of the second deviation correction device 2 can also be provided as an unslotted flat plate structure.
Finally, it should be noted that: the above examples are only intended to illustrate the technical solution of the present invention and not to limit it; although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art will understand that: modifications to the specific embodiments of the invention or equivalent substitutions for parts of the technical features may be made; without departing from the spirit of the present invention, it is intended to cover all aspects of the invention as defined by the appended claims.
