Description

Technical Field

[0001] This application relates to a clamping fixture for drilling holes in automotive steel rings, belonging to the field of automotive parts processing and manufacturing technology. Background Technology

[0002] In the automotive manufacturing industry, steel rings are key components widely used in many critical parts such as engines, transmission systems, and braking systems. For example, in automotive wheel hub units, steel rings are an important part of the bearing, and their quality directly affects the rotational accuracy and stability of the wheel hub, thus affecting the driving safety and comfort of the vehicle; in the universal joint of the drive shaft, steel rings also play an important role in transmitting power and ensuring the flexibility of movement.

[0003] With the rapid development of the automotive industry, the requirements for the precision and quality of automotive parts are increasing. The machining of holes in steel rings is a crucial process in steel ring manufacturing. The positional accuracy, dimensional accuracy, and surface quality of these holes have a vital impact on the assembly and performance of the steel ring. Taking automotive wheel hub bearing steel rings as an example, the bolt holes on them need to be precisely machined to ensure accurate assembly of the wheel hub with components such as the wheel and brake disc. Excessive deviation in the hole position may lead to improper wheel hub installation, causing vibration and noise during vehicle operation, and even affecting driving safety.

[0004] Traditional clamping methods often have several drawbacks. Some simple fixtures cannot provide sufficient and uniform clamping force, causing the steel ring to easily shift or vibrate during drilling, thus affecting drilling accuracy and resulting in significant hole position deviations, which in turn affect subsequent assembly quality. In addition, some fixtures have low positioning accuracy, failing to guarantee that the steel ring is in the correct position during each processing, leading to poor product consistency, increased scrap rate, and higher production costs.

[0005] With the continuous development of the automotive industry, the requirements for the processing quality of automotive steel rings are becoming increasingly stringent, and the market demand for high-precision and high-stability automotive steel ring drilling fixtures is becoming increasingly urgent. Therefore, developing a special clamping fixture capable of accurately positioning and stably clamping automotive steel rings is of great practical significance for improving the processing quality and production efficiency of automotive steel rings. Summary of the Invention

[0006] The purpose of this application is to provide a clamping fixture for drilling automotive steel rings, so as to solve the problems of inaccurate positioning and uneven clamping in the existing technology of drilling automotive steel rings, improve drilling accuracy and product quality, and reduce scrap rate.

[0007] The technical problem to be solved in this application is achieved by the following technical solution: A clamping fixture for drilling holes in automotive steel rings includes: The base provides an installation platform for other components, ensuring the stability of the tooling as a whole during the processing, and a first threaded hole is provided at the center of the base; A tubular annular limiting component is fixedly connected to the base and coaxially arranged with the base. It is used to insert the target automotive steel ring by means of gap insertion to ensure the stability of the initial positioning. An annular fastening plate, wherein a through hole is provided at the center of the annular fastening plate, and after the target automotive steel ring is initially positioned by the tubular annular limiting component, the annular fastening plate presses against the outside of the target automotive steel ring; The locking component has an external thread structure. After passing through the through hole, the locking component is screwed into the first threaded hole. When the locking component is tightened, it moves downward and applies pressure to the annular fastening plate, so that the annular fastening plate is tightly pressed against the target automotive steel ring, thereby achieving stable clamping of the target automotive steel ring. After the drilling is completed, the locking component can be loosened to remove the target automotive steel ring.

[0008] Preferably, the tubular annular limiting member has a protruding limiting block, which is adapted to the limiting groove on the target car steel ring to ensure that the target car steel ring is more accurately positioned with the tubular annular limiting member.

[0009] Preferably, a cylindrical platform is coaxially fixedly connected to the base, and an annular limiting groove is formed between the cylindrical platform and the inner wall of the tubular annular limiting member. The inner ring of the target car steel ring extends to the annular limiting groove, thereby enhancing the accuracy and stability of positioning.

[0010] Preferably, a second threaded hole is provided at the center of the cylindrical platform, and the second threaded hole is coaxially arranged and connected with the first threaded hole.

[0011] Preferably, the annular fastening plate is provided with an annular rounded corner abutment portion, which prevents damage to the target automotive steel ring.

[0012] Preferably, the locking element includes: Adjustment section; A threaded rod is fixedly connected to the adjusting part, and the threaded rod is provided with an external thread structure.

[0013] Preferably, the adjusting part is provided with a slot, which is used for engaging the lever and for tightening or loosening the locking member.

[0014] Preferably, the top circumferential of the tubular annular limiting member is provided with a plurality of preset circular holes.

[0015] The beneficial effects of this application are: 1. Precise positioning: Through the insertion of tubular annular limiting components and the cooperation between limiting blocks and limiting grooves, combined with the annular limiting groove formed by the cylindrical platform, multi-directional precise positioning of automotive steel rings can be achieved, ensuring the consistency of the steel ring position during each processing.

[0016] 2. Stable clamping: The locking mechanism applies pressure to the annular fastening plate, ensuring that the annular fastening plate is tightly pressed against the automotive steel ring. This provides a stable and reliable clamping force, effectively preventing displacement or vibration of the steel ring during the drilling process and improving drilling accuracy.

[0017] 3. Protect the steel ring: The rounded corner design of the annular fastening plate prevents damage to the automotive steel ring during clamping, ensuring the surface quality of the steel ring.

[0018] 4. Easy to operate: The slot design of the locking adjustment part makes it easy to tighten or loosen using a lever, improving work efficiency. Attached Figure Description
