Description

Technical Field

[0001] This utility model relates to the field of automotive ball joints, and more particularly to a quick clamping mechanism for automotive ball joints. Background Technology

[0002] The ball joint is a core connecting component of a car's steering and suspension systems, and its assembly stability directly affects the vehicle's handling safety and ride comfort. During automobile production and repair, the ball joint must be precisely secured using a specialized clamping mechanism to ensure the accuracy of subsequent assembly, testing, or repair operations.

[0003] In existing technologies, the clamping of automotive ball pins mostly relies on a single threaded sleeve or a simple clamp: first, the ball pin is manually screwed into the threaded hole of the clamp, and then clamping force is applied by tightening the nut or bolt. The operation requires manual control of the thread engagement and clamping force, and the assembly process is relatively traditional.

[0004] However, existing clamping mechanisms are prone to gaps due to machining errors or wear when the ball pin meshes with the internal thread of the fixture, and lack an active compensation structure. After clamping, the ball pin is prone to axial movement or radial displacement, which leads to a decrease in the accuracy of subsequent operations. Therefore, a quick clamping mechanism for automotive ball pins is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick clamping mechanism for automotive ball joints, which aims to solve the problem of insufficient fixing accuracy caused by thread clearance in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a quick clamping mechanism for automotive ball joints, comprising a base, mounting plates fixedly connected to both sides of the base, and mounting holes provided on the top of the mounting plates, a fixing mechanism provided on the top of the base, the fixing mechanism comprising a fixing cylinder, the bottom of the fixing cylinder being movably connected to the top of the base, a connecting screw fixedly connected to the bottom of the fixing cylinder, and the bottom of the connecting screw movably penetrating the top of the base and threadedly connected to a fixing nut; The inner wall of the fixed cylinder is fixedly connected with an internal thread, the bottom of the inner wall of the fixed cylinder is fixedly connected with a first spring, the top of the first spring is fixedly connected with a clamping plate, and the side of the clamping plate is slidably connected to the inner wall of the fixed cylinder. The top of the base is fixedly connected with a positioning plate, and the bottom of the outer wall of the fixed cylinder is fixedly connected with a positioning block.

[0007] As a further description of the above technical solution: a washer is sleeved on the outer wall of the connecting screw, and the washer is located above the fixing nut.

[0008] As a further description of the above technical solution: there are two positioning plates, and the two sides of the positioning block are slidably connected to the opposite surfaces of the two positioning plates respectively.

[0009] As a further description of the above technical solution: the outer wall of the fixed cylinder is provided with a clamping mechanism, the clamping mechanism includes a circular groove, the circular groove is opened at the top of the fixed cylinder, the outer wall of the fixed cylinder is provided with an insertion hole, and the insertion hole is connected to the circular groove. The inner wall of the insertion hole is slidably connected with a push rod, the outer end of the push rod is fixedly connected with a helical thread block, and the outer side of the helical thread block is threadedly connected with a threaded ring.

[0010] As a further description of the above technical solution: a second spring is fixedly connected to the side of the oblique threaded block, and the second spring abuts against the outer wall of the fixed cylinder.

[0011] As a further description of the above technical solution: a rocker arm is fixedly connected to the top of the threaded ring, a fixing rod is fixedly connected to the outer wall of the fixing cylinder, and the inner wall of the fixing rod is slidably connected to the outer wall of the threaded ring.

[0012] As a further description of the above technical solution: the abutment is provided in four sets, and each set has two abutments, both of which are fixedly connected to the inclined threaded block.

[0013] As a further description of the above technical solution: the fixed cylinder is provided with an automotive ball pin inside, and the automotive ball pin is threadedly connected to the fixed cylinder through an internal thread.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the basic fixation is achieved by the precise engagement of the inner thread of the fixed cylinder with the ball pin thread. At the same time, the first spring at the bottom of the inner wall drives the top clamping plate to press the bottom of the ball pin upward, which can actively compensate for the thread meshing gap and prevent the ball pin from moving axially. Together with the positioning plate and positioning block, the fixed cylinder is positioned to prevent rotation, which effectively ensures the accuracy of subsequent processing or assembly operations and meets the requirements for stable fixation.

[0015] 2. In this utility model, the connecting screw, fixing nut and base are detachably connected, and the corresponding fixing cylinder can be quickly replaced according to different specifications of automobile ball pins, which has strong adaptability; and the rocker arm in the clamping mechanism drives the threaded ring to rotate, which can drive multiple sets of abutment rods to clamp the outer wall of the ball pin inward at the same time. The operation is simple and labor-saving, greatly shortens the clamping operation time, and improves the efficiency of automobile ball pin assembly or repair. Attached Figure Description

The inner wall of the fixing cylinder 21 is fixedly connected to an internal thread 25, which is used to connect the car ball pin 5. The outer wall thread is used for connection, thereby fixing the car ball pin 5. The bottom of the inner wall of the fixing cylinder 21 is fixedly connected to the first spring 26, and the top of the first spring 26 is fixedly connected to the top of the first spring 26. The side of the top ...

[0021] Reference Figure 3 - Figure 4The outer wall of the fixed cylinder 21 is provided with a clamping mechanism 3, which includes a circular groove 31. The circular groove 31 is opened at the top of the fixed cylinder 21. The outer wall of the fixed cylinder 21 is provided with an insertion hole, which is connected to the circular groove 31. A stop rod 32 is slidably connected to the inner wall of the insertion hole. By setting the stop rod 32, it can abut against the outer wall of the automobile ball pin 5, thereby clamping the automobile ball pin 5. There are four sets of stop rods 32, with two stop rods 32 in each set. Setting multiple sets of stop rods 32 can improve the clamping effect. Both stop rods 32 are fixedly connected to the inclined threaded block 33. The outer end of the stop rod 32 is fixedly connected to the inclined threaded block 33. The outer thread of the inclined threaded block 33 is connected to the inclined threaded block 33. A threaded ring 35 is attached. Through the cooperation of the oblique threaded block 33 and the threaded ring 35, multiple sets of abutment rods 32 are driven to move inward to clamp the automobile ball pin 5.

Insert the car ball pin 5 into the fixing cylinder 21 and rotate the car ball pin 5. The car ball pin 5 is fixed by the internal thread 25. At the same time, the car ball pin 5 will press down on the clamping plate 27, which will drive the first spring 26 to compress. Thus, the elastic force of the first spring 26 will clamp the bottom of the car ball pin 5. Then, rotate the rocker arm 36 to drive the threaded ring 35 to rotate, so that the threaded ring 35 rotates downward, thereby causing the inclined threaded block 33 to move inward, which in turn drives the abutment rod 32 to move inward, clamping the outer wall of the car ball pin 5, making the car ball pin 5 more stable during processing.
