Milling the counterweight axle is an important process to ensure its precise fit with other components, and the quality and applicability of the tooling directly affect the machining accuracy and efficiency.

[0003] Traditional counterweight axle milling fixtures are usually integral structures. Different fixtures are required for different specifications of counterweight axles. When the specifications of the counterweight axle being processed change, the entire fixture must be replaced. This not only makes the replacement process cumbersome but also increases the cost of the fixtures, thereby increasing the processing cost of elevator parts and reducing production efficiency. Utility Model Content

[0004] In view of the problems existing in the existing counterweight wheel axle milling flat end tooling, this utility model is proposed.

[0005] Therefore, the purpose of this utility model is to provide a milling fixture for counterweight wheel shafts, which solves the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A milling fixture for counterweight wheel axles includes a base plate, support seats, and pressure plates. Multiple support seats are fixedly mounted on the upper surface of the base plate from left to right. Multiple pressure plates are positioned above corresponding support seats. The support seats and pressure plates are connected by bolts and threads. First mounting grooves are formed on both sides of the lower surface of each pressure plate, with a contoured clamping core engaging inside each groove. Second mounting grooves are formed on the upper surface of each support seat at positions corresponding to the first mounting grooves, with a contoured support core engaging inside each groove. A first limiting mechanism restricting the movement of the contoured clamping core is provided on the upper surface of the pressure plates, and a second limiting mechanism restricting the movement of the contoured support core is provided on the outer side of the support seats.

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This utility model discloses a milling fixture for counterweight wheel axles.

[0025] Reference Figure 1-4 A milling fixture for counterweight wheel axles includes a base plate 1, support seats 2, and pressure plates 4. Multiple support seats 2 are fixedly arranged on the upper surface of the base plate 1 from left to right. Multiple pressure plates 4 are arranged above the corresponding support seats 2. The multiple support seats 2 and pressure plates 4 are all connected by bolts 6 with threaded fastening. The lower surfaces of the multiple pressure plates 4 are provided with first mounting grooves on both sides. A contoured clamping core 5 is snapped into the inner side of the first mounting groove. The upper surface of the support seats 2 is provided with second mounting grooves at positions corresponding to the first mounting grooves. A contoured support core 3 is snapped into the inner side of the second mounting groove. A mounting block 7 is fixedly arranged on the upper surface of the base plate 1 and behind the multiple support seats 2. Mounting holes are provided on the surface of the mounting block 7 and the surface of the base plate 1 below it, so as to facilitate the fixed installation of the base plate 1 on the worktable.

[0026] Reference Figure 1-4 The upper surface of the pressure plate 4 is provided with a first limiting mechanism to restrict the movement of the contour clamping core 5. The first limiting mechanism includes a first wedge block 8 and a first threaded rod 9. The upper inner wall of the first mounting groove is provided with a first wedge groove. The first wedge block 8 is engaged in the inside of the first wedge groove. The first wedge block 8 is fixedly connected to the corresponding contour clamping core 5. The upper side of the wedge groove is provided with a first threaded hole. The first threaded rod 9 is threadedly sleeved in the inside of the first threaded hole. The upper side of the first wedge block 8 is provided with an insertion hole. The lower end of the first threaded rod 9 is inserted into the insertion hole. The upper end of the first threaded rod 9 is fixedly sleeved with a first knob to facilitate the rotation of the first threaded rod 9.

[0027] Reference Figure 1-4 A second limiting mechanism is provided on the outer side of the support base 2 to restrict the movement of the contour support core 3. The second limiting mechanism includes a U-shaped plate 11 and a second threaded rod 13. A second wedge-shaped groove is opened at the bottom of the second mounting groove. A second wedge-shaped block 10 is engaged inside the second wedge-shaped groove. The upper side of the second wedge-shaped block 10 is fixedly connected to the corresponding contour support core 3. The U-shaped plate 11 is abutted on the outer side of the second wedge-shaped blocks 10 on both sides. A second threaded hole is opened on the upper surface of the middle end of the U-shaped plate 11. The second threaded rod 13 is threaded into the inside of the second threaded hole. Both ends of the second threaded rod 13 are rotatably connected to a side plate 12. One side of the side plate 12 is fixedly connected to the support base 2. A second knob is fixedly sleeved on the upper end of the second threaded rod 13 to facilitate the rotation of the second threaded rod 13.

[0028] In this utility model, during use, firstly, the base plate 1 is fixedly installed on the workbench using suitable connectors such as bolts through the mounting holes on the rear side of the upper surface of the base plate 1 and the mounting block 7 and the lower surface of the base plate 1. This ensures the stability of the entire fixture during operation, providing a reliable foundation for the subsequent milling of the counterweight wheel shaft. Before clamping the counterweight wheel shaft, according to the specifications of the counterweight wheel shaft to be processed, a matching contour clamping core 5 and contour support core 3 are selected. The contour clamping core 5 is engaged in the first mounting grooves on both sides of the lower surface of the pressure plate 4, and the contour support core 3 is engaged in the second mounting groove on the upper surface of the support base 2 corresponding to the first mounting groove. The first wedge block 8 is then inserted. In the first wedge-shaped groove on the upper inner wall of the first mounting groove, since the first wedge block 8 is fixedly connected to the corresponding contour clamping core 5, the horizontal position of the contour clamping core 5 is initially defined. Then, by rotating the first knob at the upper end of the first threaded rod 9, the first threaded rod 9 moves downwards within the first threaded hole until its lower end inserts into the insertion hole on the upper side of the first wedge block 8. This further fixes the first wedge block 8, thereby restricting the movement of the contour clamping core 5 in both the vertical and horizontal directions, ensuring the stability of the contour clamping core 5 during clamping and processing. The second wedge block 10 is then inserted into the second wedge-shaped groove at the bottom of the second mounting groove. The upper side of the second wedge block 10... The U-shaped plate 11 is fixedly connected to the corresponding contour support core 3 to achieve initial horizontal positioning of the contour support core 3. Then, the U-shaped plate 11 is placed against the outer side of the second wedge blocks 10 on both sides. The second knob at the upper end of the second threaded rod 13 is rotated to make the second threaded rod 13 rotate in the second threaded hole on the upper surface of the middle end of the U-shaped plate 11. Since the two ends of the second threaded rod 13 are rotatably connected to the side plates 12, and the side plates 12 are fixedly connected to the support base 2, as the second threaded rod 13 rotates, the U-shaped plate 11 will move along the second threaded rod 13, thereby blocking the outer side of the second wedge blocks 10 on both sides, further fixing the second wedge blocks 10, and thus restricting the movement of the contour support core 3 to ensure... After the installation and positioning of the contour clamp 5 and the contour support core 3 are completed, the counterweight shaft to be processed is placed on the contour support core 3. Then, the pressure plate 4 is lowered, and the support base 2 and the pressure plate 4 are threadedly locked with bolts 6 so that the contour clamp 5 and the contour support core 3 tightly clamp the counterweight shaft. At this time, the counterweight shaft is firmly clamped in the tooling and can be milled flat. When it is necessary to process counterweight shafts of different specifications, simply reverse the above positioning steps. That is, first turn the first knob to pull the first threaded rod 9 out of the insertion hole of the first wedge block 8, and take the first wedge block 8 out of the first wedge groove. Then the contour clamp 5 can be taken out of the first mounting groove.Rotate the second knob to move the U-shaped plate 11 away from the outside of the second wedge block 10, remove the second wedge block 10 from the second wedge groove, and then remove the contour support core 3 from the second mounting groove. Replace it with a contour clamp 5 and contour support core 3 that match the new specification counterweight wheel axle. Then, follow the above limiting steps for installation and limiting. This eliminates the need to replace the entire tooling, reducing replacement costs.

[0029] In summary, this counterweight wheel axle milling fixture, through its reasonable structural design and operating procedure, achieves stable clamping and machining of the counterweight wheel axle. At the same time, it allows for easy replacement of the clamping core according to different specifications of the counterweight wheel axle, thus reducing the cost of use.
