Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling, in particular to a milling machine tooling for a tooth rail seat. Background Art

[0002] The tooth rail seat is a commonly used part on a scraper conveyor. When in use, the tooth rail seat is welded to the side of the middle trough, and a tooth rail is placed on the tooth rail seat. As Figure 8 shown, the top surface B of the tooth rail seat needs to be milled on a milling machine. However, the heights of the front plate ( Figure 8 the lower left part in Figure 8 the figure) and the rear plate ( the lower right part in

[0003] the figure) of the tooth rail seat are inconsistent. Therefore, it is impossible to place the top surface B horizontally on the milling machine workbench, resulting in the tooth rail seat can only be milled on high-end equipment such as a machining center and cannot be processed by an ordinary milling machine, thus increasing the processing cost of the tooth rail seat.

[0004] The utility model aims at the deficiencies of the prior art and provides a milling machine tooling for a tooth rail seat.

[0005] The milling machine tooling for a tooth rail seat provided by the utility model includes a pressing plate and a tooling body fixed on a milling machine workbench. The tooth rail seat is placed on the milling machine workbench and located between the tooling body and the pressing plate. A pressing screw rod horizontally passing through the tooth rail seat and the pressing plate is fixedly connected to the tooling body. A nut for pressing the pressing plate against the side surface of the tooth rail seat is installed on the pressing screw rod. A cushion plate is placed between the front plate of the tooth rail seat and the milling machine workbench.

[0006] As an optimization, the length of the cushion plate is equal to the distance from the rear plate of the tooth rail seat to the tooling body. In this scheme, both ends of the cushion plate respectively abut against the rear plate of the tooth rail seat and the tooling body, thereby further ensuring the accuracy of the fixed position of the tooth rail seat.

[0007] As an optimization, the tooling body includes a tooling bottom plate and a tooling vertical plate fixedly connected to one end of the tooling bottom plate. The tooth rail seat is arranged on the side of the tooling vertical plate away from the tooling bottom plate. In this scheme, the tooling bottom plate is fixed on the milling machine workbench, and the tooth rail seat is fixed on the side surface of the tooling vertical plate.

[0008] As an optimization, a tool setting block is fixedly connected to the upper end of the tooling vertical plate. During processing, the milling cutter is based on the tool setting block, so that the processing dimensions of the tooth rail seat can be guaranteed.

[0009] As an optimization, the tool setting block is fixedly connected to the tooling vertical plate through bolts, facilitating the replacement of the tool setting block to adapt to tooth rail seats of different sizes.

[0010] As an optimization, a rib plate is fixedly connected between the tooling vertical plate and the tooling bottom plate. The rib plate in this solution improves the connection strength between the tooling vertical plate and the tooling bottom plate and enhances the anti-deformation ability.

[0011] As an optimization, the pressing screw rod is fixedly connected to the tooling vertical plate through two nuts, enabling the pressing screw rod to be detachable.

[0012] As an optimization, a screw rod through hole for the pressing screw rod to pass through is formed on the pressing plate, and the screw rod through hole extends downward through the pressing plate. During use, without removing the nut for pressing the pressing plate, the pressing plate can be placed downward on the pressing screw rod.

[0013] The beneficial effects of the present utility model are as follows: A tooth rail seat milling machine tooling of the present utility model realizes the fixation and positioning of the tooth rail seat through this tooling, thereby enabling the fixation of the horizontal state of the top surface of the tooth rail seat, and thus enabling the machining of the top surface of the tooth rail seat through an ordinary milling machine, reducing the machining cost and improving the machining efficiency.

[0024] To clearly illustrate the technical features of this solution, the following will elaborate on this solution through specific implementation manners.

[0025] As Figures 1 - 8 shown, a tooth rail seat milling machine tooling of the present utility model includes a pressure plate 3 and a tooling body 1 fixed on a milling machine workbench 7. The pressure plate 3 is located on one side of the tooling body 1. The tooth rail seat 5 is placed on the milling machine workbench 7 and is located between the tooling body 1 and the pressure plate 3.

[0026] The tooling body 1 includes a tooling bottom plate 11 and a tooling vertical plate 12 fixedly connected to one end of the tooling bottom plate 11. The tooling vertical plate 12 and the tooling bottom plate 11 form an L-shaped structure. The tooling vertical plate 12 and the tooling bottom plate 11 are perpendicular to each other, keeping the tooling vertical plate 12 in a vertical state. The tooth rail seat 5 is arranged on the side of the tooling vertical plate 12 away from the tooling bottom plate 11, so that the tooth rail seat 5 can be attached to the vertical surface of the tooling vertical plate 12. When the tooth rail seat 5 is placed, the top surface B of the tooth rail seat faces upward, the lower end of the rear plate of the tooth rail seat is placed on the milling machine workbench 7, and the side surface of the rail seat is attached to the tooling vertical plate 12.

[0027] A rib plate 13 is fixedly connected between the tooling vertical plate 12 and the tooling bottom plate 11. The rib plate 13 is a triangular plate. One right-angled side is welded to the tooling bottom plate 11, and the other right-angled side is welded to the tooling vertical plate 12. In this embodiment, two rib plates 13 are provided in total, thus playing a good role in strengthening the connection between the tooling vertical plate 12 and the tooling bottom plate 11.

[0028] The tooling body 1 is fixedly connected with compression screws 2 that horizontally pass through the tooth rail seat 5 and the pressure plate 3. There are two compression screws 2 and they are located in the same horizontal plane. Two screw mounting holes 14 are opened on the tooling vertical plate 12. The two compression screws 2 respectively pass through the two screw mounting holes 14. As Figure 2 shown, the compression screws 2 are fixedly connected to the tooling vertical plate 12 through two nuts, so that while the compression screws 2 are fixed, their disassembly and replacement can be realized.

[0029] Nuts for pressing the pressure plate 3 against the side surface of the tooth rail seat 5 are installed on the compression screws 2. The pressure plate 3 is provided with screw through holes 31 for the compression screws 2 to pass through. The screw through holes 31 extend downward through the pressure plate 3. During use, the nuts pressing the pressure plate can be not disassembled, and the pressure plate can be placed on the compression screws from above.

[0030] A backing plate 4 is placed between the front plate of the tooth rail seat 5 and the milling machine workbench 7. The thickness of the backing plate 4 is equal to the height difference between the lower end of the rear plate of the tooth rail seat 5 and the lower end of the front plate of the tooth rail seat 5, so that the front plate of the tooth rail seat 5 is supported on the backing plate 4, keeping the upper end of the tooth rail seat horizontal.

[0031] The length of the backing plate 4 is equal to the distance from the rear plate of the tooth rail seat 5 to the tooling body 1. The two ends of the backing plate respectively abut against the rear plate of the tooth rail seat and the tooling body, further ensuring the accuracy of the fixed position of the tooth rail seat.

[0032] A tool setting block 6 is fixedly connected to the upper end of the tooling vertical plate 12. The tool setting block 6 is fixedly connected to the tooling vertical plate 12 by bolts, facilitating the replacement of the tool setting block 6.

[0033] The usage method of the present utility model: Fix the tooling body at the position shown in the figure on the milling machine workbench 7 with bolts. Then place one side of the tooth rail seat 5 on the backing plate 4, and make the side tightly lean against the side positioning surface of the tooling body 1 for positioning. Press the tooth rail seat 5 tightly with the pressing plate 3. Start the milling machine, operate the handle, and adjust the position of the milling cutter head 8 up and down. Taking the tool setting block 6 as the reference, the machining dimensions of the tooth rail seat 5 can be ensured, and then start machining. After the machining is completed, loosen the nut on the pressing screw 2, remove the tooth rail seat, and conduct inspection to complete this process.
