[0039] Example

[0040] like Figures 1 to 5 As shown, an embodiment of the present invention provides an electric rail fat edge milling machine.

[0041] like Figure 1It is a three-dimensional structural diagram of the electric rail fat edge milling machine described in an embodiment of the present invention. Figure 1 In the embodiment, the milling machine includes a frame 200 that spans two rails 100 and moves along the rails 100 , and a transverse movement mechanism 300 is installed on the frame 200 , and the transverse movement mechanism 300 can move on the frame 200 in a direction perpendicular to the rails 100 .

[0042] The transverse movement mechanism 300 is provided with a longitudinal movement mechanism 400 , and the longitudinal movement mechanism 400 is provided with a milling mechanism 500 ; the longitudinal movement mechanism 400 is used to adjust the height of the milling mechanism 500 , thereby adjusting the grinding force of the milling mechanism 500 on the rail 100 .

[0043] The transverse movement mechanism 300 is also provided with a milling angle deflection mechanism 600 , which is used to adjust the deflection angle of the longitudinal movement mechanism 400 in a vertical plane perpendicular to the rail 100 , thereby adjusting the grinding angle of the rail 100 by the milling mechanism 500 .

[0044] The frame 200 spans two corresponding rails 100, and a transverse mechanism 300 is installed on the frame 200, a longitudinal mechanism 400 is installed on the transverse mechanism 300, and a milling mechanism 500 is installed on the longitudinal mechanism 400. The transverse position of the longitudinal mechanism 400 and the milling mechanism 500 on the frame is adjusted by the transverse mechanism 300. When the rail needs to be ground, the grinding wheel of the milling mechanism 500 is adjusted to the top of the rail by the transverse mechanism 300, and the height of the milling mechanism 500 from the rail and the contact force between the grinding wheel and the rail are adjusted by the longitudinal mechanism 400, so as to adjust the grinding force of the rail. The milling angle deflection mechanism 600 can adjust the deflection angle of the longitudinal mechanism 400 in the vertical plane perpendicular to the rail 100, so as to adjust the grinding angle of the milling mechanism 500 on the rail 100.

[0045] The rail grinding quality can be controlled by adjusting the rail grinding force and the Dharma angle.

[0046] Figure 2 FIG. 1 is a structural diagram of a milling machine according to an embodiment of the present invention. Figure 2 As shown, the frame 200 includes two cross bars 1, and a longitudinal bar 2 is connected between the two cross bars 1. The frame 200 is equipped with a running wheel 3, and the running wheel 3 can run on the rail 100, thereby driving the frame 200 to move on the rail 100. The running wheel 3 can be driven on the rail 100 by an external force. For example, the operator provides a thrust or a pull force to the frame by holding the lifting handle, so that the running wheel 3 drives the frame to move on the rail, changes the position of the milling machine as a whole on the rail 100, and realizes grinding of different positions of the rail.

[0047] Figure 3 As shown, the transverse movement mechanism 300 of the milling machine described in the embodiment of the present invention includes a transverse movement frame 4, on which a U-shaped wheel 5 corresponding to the cross bar 1 is installed; the U-shaped wheel 5 can rotate on the cross bar 1, thereby driving the transverse movement frame 4 to move on the cross bar 1; one end of the transverse movement frame 4 is pivoted with a connecting rod 6, and the other end of the connecting rod 6 is pivoted to a pressure rod 7, and the bottom end of the pressure rod 7 is pivoted to the cross bar 1.

[0048] The pressure rod 7, the connecting rod 6, the transverse frame 4 and the crossbar 1 together form a four-bar linkage. Figure 3 As shown, when the pressure rod 7 is pressed downward, the connecting rod 6 moves to the right, and the connecting rod 6 moves to the right to give the traverse frame 4 a rightward thrust, thereby pushing the traverse frame 4 to move to the right side of the cross bar 1 under the drive of the U-shaped wheel 5. When the pressure rod 7 is lifted upward, the connecting rod 6 moves to the left, and the connecting rod 6 moves to the left to give the traverse frame 4 a leftward pulling force, thereby pulling the traverse frame 4 to move to the left side of the cross bar under the drive of the U-shaped wheel 5.

[0049] like Figure 3 As shown, the milling angle deflection mechanism 600 of the milling machine according to the embodiment of the present invention comprises a spindle 8 mounted on the transverse frame 4, a longitudinal support frame 9 is rotatably mounted on the spindle 8, an arc-shaped rack plate 10 is provided on one side of the longitudinal support frame 9; a scale is provided on the arc-shaped rack plate 10;

[0050] A deflection hand wheel bracket 11 is installed on the transverse movement frame 4 , and a deflection hand wheel 12 is installed on the deflection hand wheel bracket 11 . One end of the wheel shaft of the deflection hand wheel 12 is meshed with the rack 38 on the arc-shaped rack plate 10 .

[0051] When the deflection hand wheel 12 is rotated, the arc-shaped rack plate 10 meshed with one end of the wheel shaft of the deflection hand wheel 12 will also rotate accordingly. Since the arc-shaped rack plate 10 is an arc convex upward, the longitudinal support frame 9 fixedly connected to the arc-shaped rack plate 10 will also rotate on the core shaft 8 accordingly. For example, a through hole 40 is provided at the lower part of the longitudinal support frame 9, and the core shaft 8 can move through the through hole 40, so that the longitudinal support frame 9 can rotate on the core shaft. The longitudinal support frame 9 realizes the rotation in the vertical plane perpendicular to both rails on the core shaft 8, thereby realizing the adjustment of the angle between the longitudinal support frame 9 and the vertical line.

[0052] An arc scale can be set on the arc-shaped upper surface of the arc-shaped rack plate 10, and a marking line can be set on the longitudinal support frame 9. The deflection angle of the longitudinal support frame 9 can be read out by the markings on the arc scale corresponding to the engraved lines on the marking line, thereby making the angle adjustment more precise.

[0053] like Figure 4As shown, the longitudinal movement mechanism 400 of the milling machine described in the embodiment of the present invention includes a vertical guide rail 13 installed on the other side of the longitudinal movement support frame 9, a slider 14 is provided on the vertical guide rail 13, and a bearing platform 15 is provided on the slider 14; a screw bracket 16 is provided on the upper part of the longitudinal movement support frame 9, and a through sleeve 17 with an internal thread is provided on the bearing platform 15, and a screw 18 can be rotatably passed through the screw bracket 16 and then threadedly connected with the through sleeve 17; the top end of the screw 18 is connected to a longitudinal movement handwheel 19.

[0054] By rotating the longitudinal hand wheel 19 , the screw rod 18 is driven to rotate, and the rotation of the screw rod 18 drives the bearing platform 15 to move up and down along the longitudinal support frame 9 under the cooperation of the slider 14 and the vertical guide rail 13 through the penetrating sleeve 17 .

[0055] like Figure 5 As shown, the milling mechanism 500 of the milling machine described in the embodiment of the present invention includes a driving device 20 installed on the supporting platform 15; the milling mechanism 500 also includes a mounting support frame 23, and a vertical frame 24 is provided on one side of the mounting support frame 23; the other side of the mounting support frame 23 is sequentially mounted with a louver wheel 21 and a milling cutter disc 22; the rotating shaft of the driving device 20 can rotatably pass through the vertical frame 24 and then be connected to a double-toothed driving wheel 25, and the double-toothed driving wheel 25 is respectively connected to a first driven gear 28 and a second driven gear 29 through a first rack transmission belt 26 and a second rack transmission belt 27; the rotating shaft of the louver wheel 21 can rotatably pass through the side plate of the mounting support frame 23 to be connected to the first driven gear 28, and the rotating shaft of the milling cutter disc 22 can rotatably pass through the side plate of the mounting support frame 23 to be connected to the second driven gear 29.

[0056] The driving device 20 may be a servo motor. A power box 30 and an electrical box 37 are also mounted on the frame 200. The power box 30 provides power to the electrical box 37 and the servo motor, and the electrical box 37 controls the rotation speed of the servo motor.

[0057] The rotation of the servo motor drives the double-toothed driving wheel 25 to rotate, and the rotation of the double-toothed driving wheel 25 drives the first driven gear 28 to rotate through the first rack transmission belt 26. The rotation of the first driven gear 28 drives the shutter wheel 21 to rotate, and the rotation of the shutter wheel 21 realizes the grinding of the fat edge of the rail; the rotation of the double-toothed driving wheel 25 drives the second driven gear 29 to rotate through the second rack transmission belt 27, and the rotation of the second driven gear 29 drives the rotation of the milling cutter disc 22, and the rotation of the milling cutter disc 22 realizes the milling of the fat edge of the rail.

[0058] Combination Figure 4When the longitudinal shift hand wheel 19 is rotated, the carrying platform 15 moves up and down, and the servo motor moves up and down with the carrying platform, thereby driving the vertical frame 24 to move up and down through the rotating shaft of the servo motor, and the vertical frame 24 drives the entire milling mechanism to move up and down, thereby adjusting the contact force between the shutter wheel 21 and the milling cutter disc 22 and the rail.

[0059] Combination Figure 3 When the deflection hand wheel 12 is rotated, the longitudinal support frame 9 deflects left and right. The deflection of the longitudinal support frame 9 drives the deflection of the bearing platform. The servo motor deflects left and right with the bearing platform, thereby driving the entire milling mechanism to deflect left and right through the vertical frame 24 through the rotating shaft of the servo motor, thereby adjusting the contact angle between the shutter wheel 21 and the milling cutter disc 22 and the rail.

[0060] Specifically, in order to realize the rotation of the louver wheel and the milling cutter disc driven by the double-toothed driving gear, the side panels of the mounting support frame 23 are successively provided with a first bearing seat 30 and a second bearing seat, and bearings are installed in the first bearing seat 30 and the second bearing seat. The rotating shaft of the louver wheel 21 passes through the bearing in the first bearing seat 30 and is connected to the first driven gear 28, and the rotating shaft of the milling cutter disc 22 passes through the bearing in the second bearing seat and is connected to the second driven gear 29.

[0061] The traverse frame 4 is also provided with a handrail 32; the frame 200 is provided with a lifting handle 33; the side plate of the mounting support frame 23 is provided with a protective cover 34, and the protective cover 34 is located above the shutter wheel 21 and the milling cutter disc 22. The setting of the protective cover 34 can prevent debris from splashing, avoid physical harm to the operator, and make it safer to use.

[0062] A first limit lever 35 is fixed on the cross bar 1, and a second limit lever 36 corresponding to the first limit lever 35 is fixed on the transverse frame. During the normal angle fat edge milling process and the variable angle milling process, the second limit lever 36 corresponding to the first limit lever 35 contacts at the movement limit position, thereby realizing the limit control of the milling process.

[0063] In summary, the electric rail fat edge milling and grinding machine described in the embodiment of the present invention uses a milling cutter disc and a louver wheel as milling and grinding tools, an electric motor as a power source, and a rechargeable lithium battery to power the electric motor. When the grinder is in operation, the motor drives the milling cutter disc and the louver wheel to grind, and the longitudinal feed of the processing tool system is achieved by turning the hand wheel, and the lateral position and grinding angle of the abrasive belt wheel system are adjusted by the transverse pressure rod and the swinging hand wheel. At the same time, the limit system realizes the position limit of the milling and grinding operation to ensure the safety of the processing. During the grinding operation, the milling cutter disc first contacts the fat edge disease and performs milling processing on the fat edge. The milling processing can ensure the efficiency of the processing and reduce the labor intensity; the louver wheel grinds the milling surface, which increases the accuracy of the processing surface and improves the processing quality. The use of the motor also makes the processing process more environmentally friendly.

The components in the above embodiment can be combined into one component, or can be further divided into multiple sub-components.
