Description

Technical field

[0001] The utility model relates to the technical field of ball head connecting rod flange installation equipment, in particular to a ball head connecting rod flange pulling device. [Background Technology]

[0002] The tie rod ball joint assembly is used to connect the steering gear and the steering wheel in the automobile chassis structure to ensure the safety of wheel steering and bouncing. It is a key component in the independent suspension chassis steering system. Therefore, the design and manufacturing level of the steering tie rod ball joint assembly directly affects the stability of the vehicle's driving. If there are problems with the design and manufacturing technology of the steering tie rod ball joint assembly, the vehicle's steering wheel will become loose, tremble, or difficult to return to its original position, or even lose direction. The existing tie rod ball joint assembly is mainly composed of a tie rod body with a ball seat, a ball head, a sealing cover, a sealing gasket and a flange. When installing the tie rod ball joint, the person can put the ball head on the ball seat and The sealing cover is placed on the ball seat to seal one end of the ball head, and the sealing gasket is used to seal the other end of the ball head. Once the ball head is sealed, the personnel will install the flange on the connecting rod of the ball head to achieve the installation of the tie rod ball head assembly. The installation of the flange will use a flange installation device. The existing flange installation device mainly requires personnel to place the flange on the ball head rod in advance, and insert the ball head with the flange into the positioning seat. The ball seat is pressed by the movement of the pressure block, so that the flange is supported by the positioning seat and the pressure of the pressure block, so that the ball head is pressed into the ball head, thereby achieving the installation of the flange.

[0003] Although the flange can be installed through the above scheme, the following problems still exist: the above scheme mainly uses the positioning seat to position and support the ball head and the flange, and uses the pressure block to test the sealing cover. Although this method can install the flange, it is easy to cause the sealing cover to be depressed in the middle due to pressure by pressing the flange onto the ball head during the pressure test of the sealing cover. Once the sealing cover is depressed in the middle, the depressed part of the sealing cover will contact the ball head, which can easily cause the ball head to become stuck when turning. [Utility Model Content]

[0004] The purpose of the utility model is to solve the problems in the prior art and to provide a ball head connecting rod flange pulling device, which can be used to install flanges.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes a ball head connecting rod flange device, comprising: a base,

[0006] Also includes:

[0007] A positioning seat, the positioning seat being detachably fixedly connected to the top surface of the base;

[0008] A positioning plate, the positioning plate being detachably connected to the top surface of the positioning seat, and a positioning hole for the ball head connecting rod to enter is formed through the positioning plate and the positioning seat;

[0009] A threaded barrel, wherein the threaded barrel is driven to rotate and connected in the positioning seat, and the threaded hole on the threaded barrel is arranged opposite to the positioning hole;

[0010] The rubber block is driven to rise and fall and is connected to the base, and the rubber block is arranged opposite to the positioning hole.

[0011] Preferably, a movable disk is slidably connected to the base, and the movable disk is fixed to the rubber block by bolts. A cylinder 1 is fixedly connected to the base, and the output shaft of the cylinder 1 is fixed to the top surface of the movable disk by bolts.

[0012] Preferably, a sliding rod is slidably connected to the top surface of the base, and one end of the sliding rod is fixedly connected to an end of the movable plate away from the positioning seat.

[0013] Preferably, a positioning groove is provided on the positioning seat, and the positioning plate is placed on the positioning groove.

[0014] Preferably, a bolt 1 is rotatably connected to the positioning seat, and one end of the bolt 1 is threadedly connected to the base.

[0015] Preferably, a motor 1 is fixedly connected to the base, and an output shaft of the motor 1 is fixedly connected to the threaded barrel.

[0016] Preferably, the positioning hole is provided with a chamfer.

[0017] The beneficial effects of the present invention are as follows: compared with the prior art, the present invention rotates the threaded barrel connected to the base to drive the ball head pull rod to move downward under the influence of the thread, and in order to prevent the pull rod from rotating, the rubber block is lifted and lowered to press the pull rod ball seat to prevent the ball seat from rotating. Once the ball head pull rod moves downward, the flange will enter the ball head, thereby realizing the installation of the flange plate. The threaded barrel is threadedly connected to the connecting rod on the ball head, and the threaded barrel is rotated to pull the connecting rod and the ball head downward, and the flange will enter the ball head, thereby realizing the installation of the flange, thereby reducing the pressure deformation of the sealing cover during installation, which affects the smoothness of the subsequent ball head steering.

[0029] The positioning seat 1 is disassembled and fixedly connected to the top surface, and the positioning plate 2 is placed on the positioning seat 1. The positioning plate 2 is used to support the ball seat. It is worth mentioning that a positioning hole 4 for the ball head connecting rod to enter is passed through the positioning seat 1 and the positioning plate 2. The positioning hole 4 is convenient for the positioning rod on the ball head to be placed in. When the positioning rod is placed in the positioning hole 4 and connected to the threaded hole, the rubber block 5 connected to the base 13 is driven to move, and the ball seat is pressed with the rubber pad, and the threaded barrel 3 connected to the positioning seat 1 is driven to rotate, so that the threaded barrel 3 drives the ball seat connecting rod threadedly connected to it to move. When the ball head moves downward, the flange will be pushed by the positioning plate 2 into the ball head, thereby realizing the installation of the flange.

[0030] Specifically, the movable plate 6 is slidably connected to the base 13, and the movable plate 6 is fixed to the rubber block 5 by bolts, which makes it easy for personnel to remove the rubber block 5. The cylinder 17 is fixedly connected to the base 13, and the output shaft of the cylinder 17 is fixed to the top surface of the movable plate by bolts. The output shaft of the cylinder 17 can drive the movable plate 6 to drive the rubber block 5 to move, making it easy for the rubber block 5 to press the ball seat.

[0031] Specifically, a sliding block is slidably connected to the top surface of the base 13, and one end of the sliding rod 8 is fixedly connected to the end of the movable disk 6 away from the positioning seat 1, thereby limiting the movable disk 6 and preventing the movable disk 6 from rotating.

[0032] Specifically, a positioning groove 9 is opened on the positioning seat 1 , and the positioning disc 2 is placed on the positioning groove 9 to facilitate positioning of the positioning disc 2 . The positioning disc 2 is circular, and the shape of the corresponding positioning groove 9 is adapted to the positioning disc 2 .
