DETAILED DESCRIPTION

[0027] The following will be described in detail with reference to the accompanying drawings. Figures 1-7 The present application is further described in detail.

[0028] The present application discloses a double-head inclined surface milling machine for conductive rods.

[0029] With reference to Figure 1 and Figure 2 , the double-head inclined surface milling machine for conductive rods comprises a rack 1 having an opening on one side for placing and taking materials, two sliding seats 2 symmetrically arranged in the rack 1 along the length direction of the rack 1, and two lead screw driving mechanisms respectively used for driving the two sliding seats 2 to move towards each other. The two sliding seats 2 are coaxial, and the two lead screw driving mechanisms are respectively located at the two ends of the rack 1 along the length direction.

[0030] The purpose of this design is to make the device suitable for the requirement of simultaneously processing the two ends of conductive rods of different lengths, to improve the processing efficiency, and to achieve the purpose of simplifying the processing procedure.

[0031] With reference to Figure 2 and Figure 3 , the top ends of the two sliding seats 2 are located on the same horizontal plane, and a vertical milling head 211 and a horizontal milling head 221 are arranged on each sliding seat 2. The vertical milling head 211 is drivingly connected with a vertical motor 21 along the vertical direction, and is used for milling the top side of the conductive rod. The horizontal milling head 221 is movably arranged along the width direction of the conductive rod, and is drivingly connected with a horizontal motor 22, and is used for simultaneously milling the side surface of the conductive rod.

[0032] The vertical motor 21 and the horizontal motor 22 are respectively connected with the lead screw driving mechanisms located on the sliding seats 2, so that the present application can achieve accurate milling for conductive rods of different transverse sizes, and also makes it easier to place the conductive rod to the predetermined milling position.

[0033] The screw rod driving mechanism described in the application specifically comprises a driving motor and a screw rod fixedly connected with the output shaft of the driving motor, the screw rod is threadedly connected with a component that needs to be moved, and the component can only slide back and forth in one direction.

[0034] Because the screw rod driving mechanism belongs to the prior art and is a relatively common and traditional driving mode, the same is not separately shown in the drawings of the application. Meanwhile, the application contents achieved by other driving modes also belong to simple transformations based on the application and should be included in the protection scope of the application.

[0035] With reference to Figure 3 and Figure 4 , two positioning assemblies 4 are connected with the top sides of the two sliding seats 2 near the opening end of the rack 1, so as to limit the conductive rod and avoid the conductive rod from shaking during the milling process, thereby causing processing errors.

[0036] The positioning assembly 4 specifically comprises two base plates 41 mounted on the top sides of the two sliding seats 2 near the opening end of the rack 1 and two positioning blocks 42 detachably connected to the two base plates 41. The length direction of the positioning block 42 is parallel to the length direction of the rack 1, and a positioning V-shaped groove 421 is formed in the top side of the positioning block 42 along the length direction, so as to facilitate the inclined placement of the conductive rod and realize the simultaneous milling of the two vertical surfaces. The positioning plate 43 is adjustably connected to the side of the positioning block 42 away from the other positioning block 42 through a bolt, and the two positioning plates 43 together realize the limiting effect on the two ends of the conductive rod along the axial direction.

[0037] The bolt connection between the positioning plate 43 and the positioning block 42 is designed to enable the positioning block 42 to abut against the end of the conductive rod through fine adjustment when the two ends of the conductive rod are respectively placed on the two positioning blocks 42, thereby avoiding the axial displacement of the conductive rod during milling.

[0038] Further, the oil cylinder 44 is arranged on each base plate 41, and the pressing block 45 is rotatably sleeved on the output shaft at the top end of the oil cylinder 44. The pressing block 45 is provided with a pressing V-shaped groove 451 on the side close to the base plate 41, and the pressing V-shaped groove 451 is connected with the upper end of the conductive rod during the milling of the conductive rod, thereby realizing the complete positioning of the conductive rod.

[0039] Further, the guide block 5 is arranged on the base plate 41 away from the positioning plate 43 on the side of the positioning block 42. The axis of the guide block 5 is collinear with the axis of the positioning block 42, and a guide V-shaped groove 51 is formed in the top side of the guide block 5, which is the same as the positioning V-shaped groove 421, so as to provide support for the middle part of the conductive rod and prevent the conductive rod from being bent or broken due to excessive internal stress during the milling.

[0040] Preferably, when the pressing block 45 is clamped with the conducting rod, the guiding block 5 and the pressing block 45 are located in the same vertical plane. And the pressing V-shaped groove 451 and the guiding V-shaped groove 51 jointly form an enclosing effect on the conducting rod, so that the conducting rod can be completely limited while avoiding excessive pressing force of the pressing block 45 on the conducting rod, thereby generating excessive shear internal stress.

[0041] With reference to Figure 4 and Figure 7 Preferably, the two base plates 41 are further detachably provided with a tool setting structure 6 on the side away from the positioning block 42, so that the conducting rod can be quickly positioned at the predetermined machining position when machining conducting rods of different sizes, thereby simplifying the operation steps. The tool setting structure 6 specifically comprises a tool setting seat 61 detachably connected to the base plate 41 and a tool setting rod 62 vertically hinged to the top end of the tool setting seat 61. The tool setting rod 62 has a predetermined spacing with the positioning block 42 in the axial direction of the conducting rod, and when machining conducting rods of different sizes, the tool setting rod 62 can quickly determine the installation position of the positioning block 42.

[0042] With reference to Figure 5 and Figure 6 The rack 1 is provided with a displacement mechanism 7 for moving the conducting rod, which is used to move the machined conducting rod away from the milling station and move the conducting rod to be machined to the milling station. The displacement mechanism 7 comprises a mounting seat 71 arranged in the middle of the rack 1 along the length direction, a transverse cylinder 72 connected to the mounting seat 71, and a vertical cylinder 73 fixedly connected to the output end of the transverse cylinder 72. The vertical cylinder 73 is perpendicular to the transverse cylinder 72, and the telescopic rod end of the vertical cylinder 73 is located at the top of the cylinder. The telescopic rod end of the vertical cylinder 73 is connected with a horizontally placed supporting plate 74, and the top side of the supporting plate 74 is in abutment with the conducting rod. The two base plates 41 are commonly provided with a feeding assembly 8 to facilitate the workers to take down the machined conducting rod and place the conducting rod to be machined.

[0043] When the conducting rod is machined, the worker places the conducting rod on the feeding assembly 8, at which time the transverse cylinder 72 and the vertical cylinder 73 jointly act to move the supporting plate 74 to the position of the conducting rod. Then the supporting plate 74 moves to move the conducting rod to the milling station. When the machining of the conducting rod is completed, the displacement mechanism 7 is reversely operated to move the machined conducting rod to the feeding assembly 8.

[0044] This design aims to make the taking and placing of the conducting rod more convenient, thereby saving labor and avoiding the problem of collision during manual operation.

[0045] With reference to Figure 6 and Figure 7Specifically, the feeding assembly 8 includes two feeding blocks 81 symmetrically mounted on the two base plates 41. The feeding blocks 81 are provided with a material blocking plate 82 on the side away from each other. The top side of the feeding block 81 is also provided with a V-shaped groove. The feeding assembly 8 is used to place the conductive rod in the designated position, which is convenient for the shifting mechanism 7 to take and place the conductive rod in the correct milling position.

[0046] Referring to Figure 1 and Figure 5 The bottom of the rack 1 is also provided with a waste removal device 9 for collecting milling waste, so as to promote the recycling of milling waste and prevent the scattering of waste in the interior of the rack 1. The waste removal device 9 includes a flat transmission belt 91 placed on the bottom of the rack 1 and a lifting transmission belt 92 placed on one side of the adjacent opening of the rack 1, and the bottom end of the lifting transmission belt 92 abuts against the flat transmission belt 91. The top of the lifting transmission belt is placed below the output end of the top and is also provided with a collection vehicle 93 for conveniently collecting and transporting waste.

[0047] In order to more effectively collect the milling waste, so that the waste falls more on the flat transmission belt 91, therefore, the rack 1 is provided with a waste collection hopper 94 below the two base plates 41, and the outlet of the bottom of the two waste collection hoppers 94 is located directly above the flat transmission belt 91.

[0048] Referring to Figure 4 and Figure 7 Preferably, the base plate 41 is provided with a protective plate 95 outside the positioning block 42 to prevent the scattering of milling waste. The bottom of the protective plate 95 has an opening, and the bottom side thereof is inclined to help the waste fall more easily onto the flat transmission belt 91.

[0049] The vertical motor 21 is provided with a flow guide pipe 3 with an outlet end close to the positioning block 42, and the flow guide pipe 3 is provided with cooling liquid to cool the milling operation and prevent the horizontal milling head 221 and the vertical milling head 211 from overheating.

[0050] The implementation principle of the double-head inclined surface milling machine for the conductive rod of the embodiment is as follows:

[0051] Firstly, the staff places the conductive rod to be processed on the feeding block 81 of the feeding assembly 8. At this time, the horizontal cylinder 72 and the vertical cylinder 73 jointly act to move the supporting plate 74 below the conductive rod, and then the supporting plate 74 drives the conductive rod to move to the positioning block 42. Then, the oil cylinder 44 drives the pressing block 45 to rotate and then move downward to completely fix the conductive rod.

[0052] Then, the horizontal motor 22 and the vertical motor 21 jointly act to drive the horizontal milling head 221 and the vertical milling head 211 to simultaneously mill the two ends of the conductive rod and the two mutually perpendicular sides on the two ends.

[0053] In this process, the debris will be carried by the cooling liquid through the debris collection hopper 94, and fall onto the flat conveyor belt 91. After being transported by the flat conveyor belt 91 and the lifting conveyor belt 92, the debris finally falls into the collection vehicle 93.

[0054] Finally, the processed conductive rod is lifted by the pallet 74 and placed on the discharge block 81, completing the integrated automatic operation of milling.

[0055] The above are preferred embodiments of the present application, and are not intended to limit the protection scope of the present application. Therefore, any equivalent changes made on the basis of the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
