Description

[Technical field]

[0001] The utility model relates to the technical field of ball pin installation equipment, in particular to a ball pin pressing device. [Background technology]

[0002] The ball pin, also known as the ball pin head, is widely used in independent suspension systems. There are two main structures: one is a combination of a ball pin and an integral ball seat, and the other is a combination of a hemispherical ball pin and a spherical component. In the past, spiral springs were mostly used for pre-stressing and compensating for wear. Now, synthetic resin ball seats with elasticity and lubrication are widely used, which not only reduces costs but also improves handling stability. In addition, the material and shape of the dust cover, the type of grease, etc. have been greatly improved, the grease nipple has been cancelled, and a maintenance-free structure has been achieved. For the installation of the ball pin head, a press-in device is generally used. The ball head is pressed into the ball seat through the press-in device, thereby realizing the assembly of the ball seat and the ball head. The existing press-in device is mainly composed of a positioning base, a press-in block, and a cylinder connection. The ball seat is placed on the positioning base, and then the ball head is placed on the ball seat, and the connecting rod on the ball head is aligned with the press-in block. The cylinder is driven to drive the press-in block to move, so that the ball head output stem is forced to press the ball head into the ball seat, thereby realizing the assembly of the ball head and the ball seat.

[0003] In the above method, the ball head and the ball seat are assembled. Although the ball seat and the ball seat can be installed, when the ball head is placed on the ball seat, the connecting rod and the press-in block on the ball head need to be arranged relative to each other. If the connecting rod is in a tilted state during the process of inserting the ball head, the press-in block will cause the connecting rod to drive the ball head to rotate when the connecting rod is pressure tested. Once the press-in block continues to pressure test while the ball head is rotating, it is easy to cause the connecting rod to contact with the ball seat and cause the connecting rod to bend. [Contents of the utility model]

[0004] The utility model aims to solve the problems in the prior art and provides a ball pin pressing device which can install a ball seat and a ball head.

[0005] To achieve the above purpose, the utility model proposes a ball pin pressing device, comprising: a base, a pressing block and a ball seat positioning seat arranged on the base.

[0006] A movable seat is elastically and relatively slidably connected to the base in a transverse direction, and a clamping block 1 is fixedly connected to the movable seat, and the clamping block 1 is located on both sides of the ball seat positioning seat;

[0007] The base is driven to slide in a vertical direction and connected with a lifting plate, the pressing block is fixedly connected to the bottom surface of the lifting plate, and the end of the pressing block away from the lifting plate is arranged opposite to the ball seat positioning seat;

[0008] A push plate is fixedly connected to the bottom of the lifting plate in a vertical direction, and the push plate is located between the two moving seats;

[0009] The pressing block is fixedly connected to the bottom surface of the lifting plate, and the pressing block is arranged opposite to the ball seat positioning seat;

[0010] The push plate is provided with two inclined surfaces with equal angles at one end close to the moving seat;

[0011] The push plate and the pressing block are arranged in a front-to-back staggered manner, and the distance between the push plate and the moving seat is equal to the distance between the pressing block and the top end of the ball head.

[0012] Preferably, the movable seats are rotatably connected with driving wheels, the two driving wheels are arranged opposite to each other, and the inclined surface can be in contact with the two driving wheels.

[0013] Preferably, the torsion spring on the clamping block 1 is connected to the clamping block 2, and the clamping block 2 is provided with a positioning hole for the ball head connecting rod to enter.

[0014] Preferably, a limiting block is fixedly connected to the clamping block 1, and the limiting block can be attached to the side wall of the clamping block 2.

[0015] Preferably, a spring telescopic rod is fixedly connected to the base, and one end of the spring telescopic rod is fixedly connected to the movable seat.

[0016] Preferably, a T-shaped sliding block is fixedly connected to the movable seat, and a T-shaped sliding groove for the sliding block to slide is provided on the base.

[0017] Preferably, a receiving groove for the push plate to enter is formed on the top surface of the base.

[0018] The beneficial effects of the utility model are as follows: compared with the prior art, the utility model moves the lifting plate arranged on the base, so that the lifting plate drives the pressing block to fit against the connecting rod. During the process of the pressing block and the connecting rod fitting against each other, the pressing block continues to test the connecting rod, and the pushing plate pushes the moving seat to move relatively, so that as soon as the clamping block releases the connecting rod, the ball head can be pressed into the ball seat. By positioning the connecting rod on the ball head in advance, the bending of the connecting rod due to tilting and pressure can be avoided. Moreover, the pressing and releasing of the connecting rod are performed simultaneously, which can avoid the situation where the ball head cannot be pressed in normally when the connecting rod is in positioning during the pressing process.

[0027] like Figure 1 to Figure 2 The utility model discloses a ball pin pressing device, comprising: a base 1, a pressing block 2 and a ball seat positioning seat 3 arranged on the base 1.

[0028] It also includes: a moving seat 4, a clamping block 5, a lifting plate 6 and a pushing plate 7;

[0029] The movable seat 4 is relatively elastically slidably connected to the base 1, and the movable seat 4 is elastically connected by a spring or a spring telescopic rod 12 (not shown in the spring structure diagram), wherein the spring is fixedly connected to the base 1, and one end is fixedly connected to the movable seat 4, so that the movable seat 4 can be driven to reset, and the clamping block 5 is fixedly connected to the movable seat 4, and the clamping block 5 is fixedly connected to the movable seat 4, and the clamping block 5 is fixedly fixed by bolts, and the bolts are rotatably connected to the clamping block 5, and one end is threadedly connected to the movable seat 4, so that the clamping block 5 can be fixed, wherein the clamping block 5 is a rectangular parallelepiped, and one end of the clamping block 5 in the length direction is located on the ball seat positioning seat 3, so that the clamping block 5 can clamp the connecting rod of the ball head, and at the same time, because the push plate 7 and the press-in block 2 are staggered front and back, the distance between the push plate 7 and the movable seat 4 is equal to the distance between the press-in block 2 and the top of the ball head, so that there will be no interference;

[0030] The lifting plate 6 is driven by the cylinder to slide in the vertical direction and is connected to the base 1. The cylinder is fixedly connected to the base 1, and one end of its output shaft is fixedly connected to the lifting plate 6, so that the lifting and lowering of the lifting plate 6 can be realized. During the lifting and lowering process of the lifting plate 6, the pressing block 2 fixedly connected to the bottom surface of the lifting plate 6 will be in contact with the connecting rod. During the contact between the connecting rod and the pressing block 2, the pushing plate 7 fixedly connected to the ground of the lifting plate 6 will push the moving seat 4 to move to both sides, so that the clamping block 5 releases the connecting rod, and the pressing block 2 continues to move, so that the connecting rod can drive the ball head into the ball seat, thereby realizing the installation of the ball seat and the ball head.

[0031] Specifically, two inclined surfaces 8 with equal angles are provided at one end of the pushing plate 7 close to the moving seat 4. The moving seat 4 is rotatably connected with a pushing wheel 9. The two pushing wheels 9 are arranged opposite to each other, and the inclined surfaces 8 can be in contact with the two pushing wheels 9. The inclined surfaces 8 are mainly used to drive the pushing wheels 9 to drive the moving seat 4 to move. Through the setting of equal inclined surfaces 8, the moving distance of the moving seat 4 can be made the same, thereby reducing the situation where one clamping block 5 is in contact with the connecting rod while the other clamping block 5 is not in contact with the connecting rod, thereby reducing the contact between one clamping block 5 and the connecting rod, increasing the friction of the connecting rod, and further improving the smoothness of pressing the ball head into the ball seat.

[0032] Specifically, the torsion spring on the clamping block 1 5 is connected to the clamping block 2 10, and a positioning hole 16 for the ball head connecting rod to enter is opened on the clamping block 10. By moving the clamping block, the connecting rod is located in the positioning hole 16 for clamping, which makes it easy for personnel to install the connecting rod on the clamping block 2 10.

[0033] Specifically, a limit block 11 is fixedly connected to the clamping block 1 5 , and the limit block 11 can be attached to the side wall of the clamping block 2 10 . The limit block 11 blocks the rotation of the clamping block 2 10 , thereby preventing the clamping block 2 10 from rotating when the movable seat 4 is released.

[0034] Specifically, a spring telescopic rod 12 is fixedly connected to the base 1, and one end of the spring telescopic rod 12 is fixedly connected to the moving seat 4. Through the design of the spring telescopic rod 12, the circular rotation of the moving seat 4 can be limited to prevent the moving seat 4 from rotating.

[0035] Specifically, a T-shaped sliding block 13 is fixedly connected to the moving seat 4 , and a T-shaped sliding groove 14 for the sliding block 13 to slide is provided on the base 1 . The sliding block 13 is mainly used to support the moving seat 4 , thereby further improving the supporting effect of the moving seat 4 .

[0036] Specifically, a receiving groove 15 for the push plate 7 to enter is formed on the top surface of the base 1 , and the receiving groove 15 is mainly used to receive the push plate 7 to prevent the push plate 7 from hitting the base 1 .

[0037] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
