Description

Technical Field

[0001] The present application relates to the technical field of tooling and fixtures, and in particular to a pressure strip chamfering tool. Background Art

[0002] As an important component of the middle seam water stop of the miter gate, the pressure strip must be processed strictly according to the requirements of the drawings during the processing. In addition to the external dimensions, flatness and straightness, the appearance quality is also one of the items for acceptance. The acceptance result directly affects the evaluation level of the gate sub-project. In previous processing projects, the chamfers on both sides of the working surface are usually processed by planers, which has low processing efficiency and the chamfered parts are relatively rough. After chrome plating, it is easy to get nodules and difficult to clean. When the milling machine is used for processing, the processing effect is better, but it is difficult to fix the pressure strip on the milling machine. Therefore, there is an urgent need for a tooling that can quickly clamp and fix the pressure strip to improve the processing efficiency and quality of the pressure strip. Utility Model Content

[0003] In order to solve the problems in the prior art that when a gantry milling machine is used to perform chamfering on a pressure strip, the pressure strip is difficult to clamp and fix, and the processing efficiency is low, the present application provides a pressure strip chamfering tool.

[0004] The present application provides a pressure strip chamfering tool adopting the following technical solution: a pressure strip chamfering tool, comprising:

[0005] A bottom plate, the bottom plate being used for connecting to a milling machine;

[0007] A top block assembly is arranged on one end of the bottom plate close to the limit plate, and the top block assembly includes a top block movably connected to the bottom plate, and one end of the top block extends above the limit plate.

[0008] By adopting the above technical scheme, when the pressure bar is chamfered, the pressure bar is placed horizontally on the inclined surface of the support frame, and the limit plate supports and limits the bottom of the pressure bar, so that the pressure bar is inclined at a certain angle, and then one end of the top block is pressed against the bottom of the pressure bar, and the top block is fixed to complete the clamping of the pressure bar. Since one side of the support frame is set as an inclined surface, the pressure bar is tilted on the milling machine through the support frame, the gantry milling machine is started, and the milling machine tool processes along the upper edge of the pressure bar, so as to achieve chamfering of the pressure bar. After the chamfering of one side of the pressure bar is completed, the pressure bar is turned over, and the above operation is repeated to achieve chamfering on both sides of the pressure bar.

[0009] Optionally, the support frame is made of angle steel, and both ends of the support frame are welded to the base plate.

[0010] By adopting the above technical solution, the support frame adopts angle steel with an angle of 90 degrees, so that when the pressure strip is placed on the inclined surface of one side of the support frame, it forms an angle of 45 degrees with the milling machine, which is convenient for processing a 45-degree chamfer.

A first threaded hole is opened at the four corners of the surface of the base plate, and a second threaded hole is opened on the base plate corresponding to the limit plate. The limit plate is fixedly connected to the base plate by the cooperation of the connecting bolts passing through the limit plate and the second threaded hole on the base plate.

[0014] By adopting the above technical solution, two base plates are provided for easy disassembly and assembly with the milling machine. The limit plate is fixed to the base plate by connecting bolts and the second threaded hole, thereby improving the connection strength between the limit plate and the base plate to achieve stable support for the pressure strip and facilitate disassembly, assembly and replacement of the limit plate.

[0015] Optionally, a locking bolt is connected through the middle of the top block, and the locking bolt is threadedly connected to the first threaded hole on the bottom plate.

[0016] By adopting the above technical solution, the top block is connected to the bottom plate through the connecting bolts, and the top block can be fixed by rotating the connecting bolts, so that the top block can be easily adjusted.

[0017] Optionally, a pad that is flush with the upper surface of the limiting plate and is used to support the top block is provided at one end of the bottom plate.

[0018] By adopting the above technical solution, the pad is used to support the top block, which makes it easier to fix the top block and improves the supporting and limiting effect on the pressure strip.

[0019] Optionally, clamping components for clamping and fixing the pressure strip are provided at both ends of the support frame.

[0020] By adopting the above technical solution, after the pressure bar is placed on one side of the support frame, the two ends of the pressure bar are fixed to the support frame through the clamping assembly, thereby further improving the clamping effect of the pressure bar and preventing the pressure bar from shifting during processing.

[0021] Optionally, the clamping assembly includes a clamping block, one end of which is threadedly connected to a clamping screw.

[0022] By adopting the above technical solution, when the pressure strip is clamped and fixed, the clamping block is clamped on the outside of the support frame and the pressure strip, and then the clamping screw at one end of the clamping block is rotated, and the pressure strip and the support frame are fixedly clamped by the cooperation of the clamping screw and the clamping block.

[0023] In summary, the present application includes at least one of the following beneficial technical effects:

[0024] 1. In the present application, a support frame is arranged on the bottom plate, and one side of the support frame is arranged as an inclined surface, so that the pressure strip can be placed on the support frame at an angle, and the limit plate cooperates with the top block to fix and support the bottom of the pressure strip, thereby realizing the rapid clamping and fixing of the pressure strip, facilitating the chamfering operation of the pressure strip by the gantry milling machine, and improving the efficiency and quality of the chamfering operation of the pressure strip;

[0038] The implementation principle of a pressure strip chamfering tool in the present embodiment is as follows: two base plates 2 are fixedly arranged on the milling machine 1, and the support frame 3 is welded to the base plate 2. When clamping the pressure strip, one end of the pressure strip is placed downward between the support frame 3 and the limit plate 4.
