Description

Technical Field

[0001] This utility model belongs to the field of piston turning positioning tooling technology, specifically relating to a turning positioning tooling for a new energy vehicle brake piston. Background Technology

[0002] Piston turning positioning fixtures are devices used to accurately fix and position pistons during piston turning. They play a key role in ensuring piston turning accuracy, improving machining quality, and increasing production efficiency. In the turning of automotive engine pistons, the use of high-precision positioning fixtures, such as a three-jaw chuck with locating pins, can ensure the dimensional accuracy and geometric tolerances of the piston, thereby improving engine performance and reliability. For fixtures that are not used for a long time, rust prevention treatment should be carried out, such as applying rust-preventive oil or using rust-preventive packaging, to prevent the fixtures from rusting and corroding.

[0003] However, when using piston turning positioning fixtures, automotive brake piston turning usually uses a chuck for fixing and positioning. However, in the limiting stage, only the bottom end of the piston is usually fixed. This method makes it impossible to fix the piston in the middle or other arbitrary positions. As a result, it is difficult to accurately position the chuck when adjusting the position of the piston on the chuck, which brings inconvenience to the operation.

[0004] To address the aforementioned issues, this application proposes a machining and positioning fixture for brake pistons in new energy vehicles. Utility Model Content

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0023] Please see Figure 1-5 The present invention provides the following technical solution: a new energy vehicle brake piston turning positioning fixture, including a fixture bracket 1, an adjusting cylinder 18 fixedly installed on the inner top wall of the fixture bracket 1, a connecting plate 5 fixedly installed on the telescopic end of the adjusting cylinder 18, two push rods 19 fixedly installed on the upper surface of the connecting plate 5, a lifting rod 20 provided at the top of each push rod 19, a sleeve 16 slidably connected to the outer surface of each lifting rod 20, the outer surface of each push rod 19 slidably connected to the inside of the sleeve 16, the outer surface of each sleeve 16 fixedly connected to the inner wall of the fixture bracket 1, a connecting plate 6 fixedly installed on the outer surface of the two lifting rods 20, a chuck 2 provided above the connecting plate 6, two marker rods 17 fixedly installed on the left side of the connecting plate 5, and two lifting scales 14 fixedly installed on the left side of the fixture bracket 1;

[0024] In this embodiment, the rod 17 and the lifting scale 14 are used. The rod 17 is aligned with the scale of the lifting scale 14. When the top rod 19 and the lifting rod 20 are raised and lowered, the adjustment amount can be easily determined by the scale of the lifting scale 14, and the chuck 2 is positioned in the vertical height.

[0025] Specifically, the piston body 3 is engaged inside the chuck 2, and two sets of fixing holes 4 are opened on the outer surface of the tooling bracket 1. In this embodiment, the fixing holes 4 are used to fix the tooling bracket 1, and bolts and other fixing devices are provided.

[0026] Specifically, the inner wall of the connecting disc 6 is threaded with two sets of double-ended bolts 7. The outer surface of each set of double-ended bolts 7 is threaded with the inner wall of the chuck 2. In this embodiment, the chuck 2 and the connecting disc 6 are connected by the double-ended bolts 7, so that the chuck 2 follows the connecting disc 6, and the position of the chuck 2 can be easily changed.

[0027] Specifically, each set of double-ended bolts 7 has a threaded anti-loosening nut 8 on its outer surface. The upper surface of each anti-loosening nut 8 is in contact with the bottom surface of the connecting plate 6. In this embodiment, the anti-loosening nut 8 is used to tighten the connecting plate 6, reducing the possibility of the connecting plate 6 and the chuck 2 coming loose, and avoiding the situation where the gap between the chuck 2 and the connecting plate 6 is too large, resulting in poor positioning accuracy.

[0028] Specifically, a support column 13 is fixedly installed on the upper surface of the tooling bracket 1. A slot 12 is opened on the upper surface of the support column 13. The outer surface of the piston body 3 is engaged with the inside of the slot 12. In this embodiment, the lower end of the piston body 3 is supported by the support column 13 and the slot 12, and the slot 12 can fix the piston body 3 to ensure the stability of the lower end of the piston body 3.

[0029] Specifically, two through screw holes 11 are provided on the outer surface of the support column 13. Each through screw hole 11 has a tightening screw 9 threadedly connected to its inner wall. In this embodiment, the piston body 3 can be tightened by moving the tightening screw 9 through the through screw holes 11 and the tightening screw 9. When the chuck 2 is located on the upper part of the piston body 3, the piston body 3 is further fixed.

[0030] Specifically, each tightening screw 9 has a support tube 10 threadedly connected to its outer surface, and the bottom surface of each support tube 10 is fixedly connected to the upper surface of the tooling bracket 1. In this embodiment, the tightening screw 9 is supported by the support tube 10, and the tightening screw 9 rotates threadedly inside the support tube 10.

[0031] Specifically, the inner sidewall of the tooling bracket 1 has two guide grooves 15. The outer surface of the connecting plate 5 is slidably connected to the inside of the guide grooves 15. In this embodiment, the guide grooves 15 can restrict the movement of the connecting plate 5 and provide guidance for the connecting plate 5, ensuring the stable lifting and lowering of the connecting plate 5.

[0032] The working principle and usage process of this utility model are as follows: When using the tooling bracket 1 to fix the piston body 3, the piston body 3 can be inserted into the chuck 2, with the lower end of the piston body 3 inserted into the slot 12. Then, the tightening screw 9 is turned, and the tightening screw 9 enters the through screw hole 11, fixing one end of the tightening screw 9 to the lower end of the piston body 3. When turning the piston body 3, the chuck 2 and the tightening screw 9 simultaneously fix the piston body 3. When it is necessary to adjust the position of the chuck 2 on the piston body 3, the chuck 2 can be loosened, and the adjusting cylinder 18 can be activated to adjust the position. The cylinder 18 drives the push rod 19 to rise through the connecting plate 5. The push rod 19 then drives the lifting rod 20. The lifting rod 20 drives the chuck 2 to rise through the connecting plate 6. After the chuck 2 reaches the appropriate position, the cylinder 18 is stopped, and the piston body 3 is fixed with the chuck 2. When adjusting the position of the chuck 2, the scale 17 will be aligned with the lifting scale 14. As the scale 17 rises, the height of the chuck 2 adjustment is determined by the scale 14, thus completing the adjustment of the chuck 2 position. Turning can be performed between the chuck 2 and the support column 13.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
