Description

Technical Field

[0001] The utility model relates to the technical field of brake valve seat plate processing, in particular to a tool for processing the brake valve seat plate by using a four-axis machining center. Background Art

[0002] The brake valve seat plate is primarily used to connect the brake valve and sensor, and to connect these components to the engineering equipment (excavator). As the intermediary component connecting the brake valve, sensor, and other components to the engineering equipment, it requires high machining precision.

[0003] There are two existing processing methods, namely horizontal machining center processing and three-axis machining center processing. Using a horizontal machining center to process the seat plate can ensure the efficiency and precision of the seat plate, but the price of a horizontal machining center is twice as high as that of a three-axis machining center. It is difficult for small-scale enterprises to purchase large quantities of horizontal machining centers, so they can only use three-axis machining centers for processing. Since the three-axis machining center does not have an A-axis, the brake valve seat plate can only be processed one surface at a time. The processing of this seat plate requires at least three clamping and processing. In terms of efficiency and precision, it cannot meet the requirements of large-scale production.

DETAILED DESCRIPTION

[0020] The present invention will be further described below with reference to the specific embodiments in the accompanying drawings.

[0021] See Figure 1-3 As shown, the utility model is a tool for machining a brake valve seat plate using a four-axis machining center, comprising a base 1, a four-axis plate 2 adapted to a three-jaw chuck 14 is provided in the middle position on one side of the base 1, two positioning plates 4 for placing a brake valve seat plate 3 are provided on the other side of the base 1, and a positioning structure for positioning the brake valve seat plate 3 is provided on the positioning plate 4. A first paving groove 8 is provided on both sides of the base 1, a screw 7 is provided on the positioning plate 4, and a pressure plate 10 for locking the brake valve seat plate 3 is provided on the screw 7. The screw 7 passes through the brake valve seat plate 3 and the pressure plate 10 in sequence and is threadedly connected to a locking piece. The entire device is first installed on the three-jaw chuck 14 of the three-axis machining center through the four-axis plate 2, and cooperates with the claws through the cylindrical pin 5 to prevent over-machining. During the process, the four-axis plate 2 and the three-jaw chuck 14 rotate relative to each other, and the base 1 is tightened by the pin in the tailstock 17, and then positioned by the locating pin 6 and the hole on the brake valve seat plate 3. The brake valve seat plate 3 fits with the locating plate 4 on the base 1, and is pressed by the pressing plate 10 and the U-shaped block 12 to complete the installation. This tooling can process two parts at a time, effectively improving work efficiency, and the entire tooling can be rotated by using the CNC dividing head to act as the A-axis in the machining center, so that four directions can be processed at one time, eliminating the tedious operations of multiple clamping required when using three-axis machining, meeting the machining requirements of the brake valve seat plate 3, and making the brake valve seat plate machining more efficient, stable and cost-effective.

[0022] Specifically, the positioning structure includes two positioning pins 6 , which are arranged diagonally on the positioning plate 4 . The two diagonally arranged positioning pins 6 can better position the brake valve seat plate 3 .

[0023] Preferably, a stepped hole 20 is provided on the base 1, and a connecting screw 19 is provided in the stepped hole 20. The connecting screw 19 passes through the stepped hole 20 and is threadedly connected to the four-axis plate 2. The four-axis plate 2 and the base 1 are assembled together through the connecting screw 19, which is convenient for assembly and later disassembly.

[0024] Furthermore, pin holes 18 are provided on the base 1 and the four-axis plate 2 , and cylindrical pins 5 are provided in the pin holes 18 . The cylindrical pins 5 play a positioning role, and the cylindrical pins 5 are interference fit with the base 1 .

[0025] Furthermore, the screw rod 7 is threadedly connected to the base 1 , and a limiting nut 9 is provided on one end of the screw rod 7 close to the base 1 to prevent the screw rod 7 from loosening.

[0026] Furthermore, the pressure plate 10 has an I-shaped structure, and second paving grooves 11 corresponding to the connecting ribs 15 of the brake valve seat plate 3 are opened on the upper and lower sides of the pressure plate 10, so that the pressure plate 10 can better press the brake valve seat plate 3.

[0027] Furthermore, the locking member is a clamping nut 13, which is threadedly connected to the screw rod 7. A U-shaped block 12 is provided between the clamping nut 13 and the pressure plate 10. The clamping nut 13 plays the role of clamping the pressure plate 10 so that the brake valve seat plate 3 can be firmly installed on the base 1. The function of the U-shaped block 12 is to reduce the distance that the clamping nut 13 needs to be screwed out. If there is no U-shaped block 12, a very large distance needs to be screwed out to remove or install the pressure plate so that there is enough space to remove the pressure plate 10.
