Description

Technical Field

[0001] This utility model relates to the field of tooling for producing leaf spring pressure plates, and in particular to a milling and positioning device for leaf spring pressure plates. Background Technology

[0002] In the production and processing of leaf springs, milling and drilling are two key processes that directly affect the accuracy and quality of the leaf spring pressure plate. Currently, most leaf spring pressure plate milling and positioning devices used by enterprises adopt a fixed structure, using simple bolt tightening or mechanical grippers to position and clamp the leaf springs. This traditional fixture has many drawbacks. First, it has poor versatility; different specifications and sizes of leaf springs require different fixtures, leading to the need for enterprises to keep multiple fixtures in stock, increasing production costs. Second, in actual operation, the adjustment method of traditional fixtures is cumbersome, requiring workers to spend a lot of time adjusting the fixtures to adapt to different sizes of leaf springs, seriously affecting production efficiency. In addition, due to the weight of the workpiece, changing leaf springs is very laborious each time.

[0003] Based on this, the present invention designs a plate spring pressure plate milling positioning device to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a milling and positioning device for a leaf spring pressure plate, thereby solving the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] The leaf spring pressure plate milling positioning device includes a clamping mechanism mounted on a fixed base. The clamping mechanism includes a centrally fixed positioning screw, and a central positioning plate fixed on each of the left and right sides of the positioning screw. The central positioning plate divides the fixed base into two symmetrical parts for placing the leaf spring. Threaded adjusting rods are installed on the left and right side walls of the fixed base. The end face of the threaded adjusting rod contacts the outer wall of the leaf spring. From bottom to top, the positioning screw is sequentially equipped with a support spring, a long strip-shaped pressure block, and a positioning nut. The positioning nut is threadedly connected to the positioning screw.

[0007] Furthermore, the fixed base is installed on the operating table, which has several horizontal positioning slots. The bottom of the fixed base has a positioning block that matches the positioning slot, and a limit block is installed on the outside of the positioning slot.

[0008] Furthermore, the limit block is rotatably connected to the limit pin through a through hole. The limit pin has threads that connect with the threaded hole reserved on the operating table.

[0009] Furthermore, the threaded adjusting rod is a threaded rod with a slotted handle fixed to its end, and the threaded adjusting rod is threaded onto an L-shaped fixed seat.

[0010] Furthermore, the short end of the L-shaped mounting base is fixed to the operating table with bolts.

[0011] Furthermore, the leaf springs are symmetrically placed on both sides of the central positioning plate.

[0012] Furthermore, the height of the center positioning plate is lower than the thickness of the leaf spring.

[0013] The present invention has the following advantages: the clamping mechanism of the present invention can be adjusted at multiple angles, and is suitable for leaf springs of different sizes. When replacing leaf springs, the supporting spring can also achieve the effect of saving effort. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0023] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-5 As shown, this utility model is a positioning device for milling a leaf spring pressure plate, including a clamping mechanism mounted on a fixed base 1. The fixed base 1 is mounted on the operating table 8 of a CNC machine tool. The operating table 8 has several horizontal positioning grooves 9. A positioning block 10 is located at the bottom of the fixed base 1, and the positioning block 10 matches the positioning grooves 9. A limiting block 11 is installed on the outside of the positioning grooves 9. The limiting block 11 is rotatably connected to a limiting pin 12 through a through hole. The limiting pin 12 has threads and is threadedly connected to a threaded hole 13 pre-drilled on the operating table 8. The position of the fixed base 1 on the operating table 8 can be finely adjusted by using the limiting block 11.

[0024] The clamping mechanism includes a centrally fixed positioning screw 2, and a central positioning plate 3 fixed on each of the left and right sides of the positioning screw 2. The central positioning plate 3 divides the fixed base 1 into two symmetrical parts. The height of the central positioning plate 3 is lower than the thickness of the leaf spring pressure plate 4 to avoid interfering with the downward pressing path of the pressure block 7.

[0025] The leaf spring pressure plate 4 is used to place the leaf spring pressure plate 4, which is symmetrically placed on both sides of the central positioning plate 3. Threaded adjusting rods 5 are installed on the left and right side walls of the fixing base 1. The threaded adjusting rods 5 are threaded rods with a slotted handle 14 fixed to their ends. The threaded adjusting rods 5 are threaded onto the L-shaped fixing base 18, whose short end is fixed to the operating table 8 by bolts. The threaded end face of the threaded adjusting rod 5 contacts the outer side wall of the leaf spring pressure plate 4. From bottom to top, the positioning screw 2 is sequentially equipped with a support spring 6, a long strip-shaped pressure block 7, and a positioning nut 17. The pressure block 7 has a hole through which the positioning screw 2 can pass, and the positioning nut 17 is threadedly connected to the positioning screw 2. The positioning nut 17 can be a wing nut, which is easy to tighten and loosen. The lower end of the support spring 6 rests against the upper surface of the fixed seat 1, and the upper end rests against the lower surface of the pressure block 7. In use, the threaded adjusting rod 5 and the positioning nut 17 are loosened, and the leaf spring pressure plate 4 is pulled out. At this time, the support spring 6 returns to its original position. Since the support spring 6 has a certain supporting force on the pressure block 7, it is not necessary to completely disassemble the pressure block 7 and the positioning nut 17. It is only necessary to directly insert the leaf spring pressure plate 4 between the pressure block 7 and the fixed seat 1, which saves time and effort.
