Description

Technical Field

[0001] This utility model relates to the field of press-fitting equipment, specifically to a press-fitting equipment for control arm ball joint pins. Background Technology

[0002] The ball joint of the control arm can support the wheel and transmit force while providing multi-directional rotational freedom, ensuring the coordinated operation of suspension movement and steering function. It is an indispensable flexible connection component in the suspension system.

[0003] The control arm and ball joint pin are fixedly connected by fastening bolts. When installing the fastening bolts, the control arm and ball joint pin need to be positioned separately. Since the relative positions of the left and right control arms and ball joint pins are different, different tooling is required when installing the ball joint pins to limit the left and right control arms at different workstations. This increases the manufacturing cost of the production equipment. Utility Model Content

[0004] The purpose of this invention is to provide a control arm ball joint pin pressing device that is compatible with the production of both left and right control arms.

[0005] To achieve the above objectives, this utility model provides a control arm ball joint pin pressing device, including a worktable, a lifting press head, a first positioning mechanism, and a control arm positioning mechanism. The first positioning mechanism is fixedly connected to the worktable for positioning the ball joint pin, the press head is located above the first positioning mechanism, and the control arm positioning mechanism is fixedly connected to the worktable.

[0006] The first positioning mechanism includes positioning holes that cooperate with fastening bolts. During the descent of the pressure head, the fastening bolts can be pressed into the two positioning holes. Two control arm positioning mechanisms are symmetrically arranged, with the two control arm positioning mechanisms located on both sides of the first positioning mechanism.

[0007] Preferably, the first positioning mechanism further includes a first support block.

[0008] Preferably, two first support blocks are arranged symmetrically.

[0009] Preferably, the first positioning mechanism further includes a second sensor, which is disposed on the worktable and is used to detect whether the ball head pin is placed in place.

[0010] Preferably, the control arm positioning mechanism includes a positioning pin and a second support block.

[0011] Preferably, the control arm positioning mechanism includes a first sensor, which is used to detect whether the control arm is placed in the correct position.

[0012] Preferably, the pressure head is connected to the worktable via a guide mechanism.

[0013] According to the above technical solution, after the ball head pin is placed in the first positioning mechanism, the mounting surface of the ball head pin and the control arm is in a horizontal state, and the second through hole on the ball head pin that cooperates with the fastening bolt is in a vertical state. When the pressure head descends, it can push the fastening bolt through the first through hole and the second through hole into the positioning hole.

[0014] The control arm positioning mechanism located on the left side of the first positioning mechanism cooperates with the left control arm. The ball head pin is placed in the first positioning mechanism. The ball head pin is located between the control arm and the first positioning mechanism. The fastening bolt is manually inserted into the first through hole of the control arm. After passing through the second through hole of the ball head pin, the fastening bolt enters the positioning hole.

[0015] The end of the fastening bolt is manually inserted into the positioning hole on the first positioning mechanism by means of rotation, etc. After these operations are completed, the pressure head is started to descend, and the fastening bolt is pressed into the positioning hole by the pressure head.

[0016] The left and right control arms share a set of positioning holes. Control arm positioning mechanisms for cooperating with the left and right control arms are respectively provided on the left and right sides of the first positioning mechanism. When using this control arm ball-head pin press-fitting equipment, simply place the left and right control arms into the corresponding control arm positioning mechanism on one side, and then place the ball-head pin into the corresponding first positioning mechanism. This fixes the relative position of the ball-head pin and the control arm. The first and second through holes, which mate with the fastening bolts, remain coaxial with the positioning holes and engage. The press head is located directly above the positioning holes. The press head does not need to move horizontally; simply pressing down on the press head and causing it to move up and down achieves the pressing of the ball-head pin fastening bolt.

[0017] Preferably, multiple pressure heads are provided under the same press, and the simultaneous operation of multiple pressure heads can tighten multiple fastening bolts.

[0018] Therefore, by setting two symmetrical control arm positioning mechanisms on both sides of the first positioning mechanism, the two control arm positioning mechanisms can cooperate with the first positioning mechanism to realize the pressing operation of the left control arm or the right control arm with the ball head pin, thereby achieving the purpose of completing the ball head pin pressing tooling in the same station and saving the fixed investment of equipment.

[0040] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0041] In this utility model, unless otherwise stated, directional words such as "above," "symmetrical," "both sides," "horizontal," "vertical," and "left side" contained in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the terminology.

[0042] See Figure 1-2 The control arm ball joint pin pressing equipment includes a worktable 1, a lifting press head 7, a first positioning mechanism 2, and a control arm positioning mechanism 3. The first positioning mechanism 2 is fixedly connected to the worktable 1 for positioning the ball joint pin. The press head 7 is located above the first positioning mechanism 2, and the control arm positioning mechanism 3 is fixedly connected to the worktable 1.

[0043] The first positioning mechanism 2 includes a positioning hole 21. During the descent of the pressure head 7, the fastening bolt 4 can be pressed into the positioning hole 21. Two control arm positioning mechanisms 3 are symmetrically arranged, with the two control arm positioning mechanisms 3 located on both sides of the first positioning mechanism 2.

[0044] By implementing the above technical solution, after the ball head pin is placed in the first positioning mechanism 2, the mounting surface 61 of the ball head pin and the control arm is in a horizontal state, and the second through hole 62 on the ball head pin that cooperates with the fastening bolt 4 is in a vertical state. When the pressure head 7 descends, it can push the fastening bolt 4 through the first through hole 51 and the second through hole 62 into the positioning hole 21.

[0045] The control arm positioning mechanism 3 located on the left side of the first positioning mechanism 2 cooperates with the left control arm. The ball head pin is placed in the first positioning mechanism 2. The ball head pin is located between the control arm and the first positioning mechanism 2. The fastening bolt 4 is manually inserted into the first through hole 51 of the control arm. The fastening bolt 4 passes through the second through hole 62 of the ball head pin and enters the positioning hole 21.

[0046] The end of the fastening bolt 4 is manually inserted into the positioning hole 21 on the first positioning mechanism 2 by means of rotation, etc. After these operations are completed, the pressure head 7 is started to descend, and the fastening bolt 4 is pressed into the positioning hole 21 by the pressure head 7.

[0047] The left and right control arms share a set of positioning holes 21. Control arm positioning mechanisms 3 are respectively provided on the left and right sides of the first positioning mechanism 2 for cooperating with the left and right control arms. When using the control arm ball head pin pressing equipment, simply place the left and right control arms into the corresponding control arm positioning mechanism 3 on one side, and then place the ball head pin into the corresponding first positioning mechanism 2. This will fix the relative position of the ball head pin and the control arm. The first through hole 51 and the second through hole 62, which cooperate with the fastening bolt 4, can remain coaxial with the positioning hole 21 and cooperate. The pressing head 7 is located directly above the positioning hole 21. The pressing head 7 does not need to move in the horizontal direction. The pressing head 7 is pressed down by the press, and the pressing head 7 moves up and down to press the fastening bolt 4 of the ball head pin.

[0048] Preferably, multiple pressure heads 7 are provided under the same press, and the simultaneous operation of multiple pressure heads 7 can tighten multiple fastening bolts 4.

[0049] Therefore, by setting two symmetrical control arm positioning mechanisms 3 on both sides of the first positioning mechanism 2, the two control arm positioning mechanisms 3 can cooperate with the first positioning mechanism 2 to realize the pressing operation of the left control arm or the right control arm with the ball head pin, thereby realizing the purpose of completing the ball head pin pressing fixture at the same station and saving the fixed investment of the equipment.

[0050] In this embodiment, preferably, the first positioning mechanism 2 further includes a first support block 22.

[0051] The first support block 22 is used to support the position where the control arm connects to the ball joint pin. In actual production, the control arm is placed first, and a recess 52 that matches the outer edge of the ball joint pin is provided at the position where the control arm connects to the ball joint pin. The side of the first support block 22 facing the recess 52 limits the side wall of the recess 52. At the same time, the upper end of the first support block 22 can also support the control arm, thereby ensuring the height of the support arm at the position where it connects to the ball joint pin. Therefore, the first support block 22 and the control arm positioning mechanism 3 work together to limit and support the control arm.

[0052] After the control arm is placed, lift the control arm and insert the ball head pin. During the insertion of the ball head pin, the recess 52 of the control arm can limit the ball head pin, while the side of the positioning hole 21 facing the ball head pin supports the ball head pin, so that the ball head pin fits against the control arm. Under the combined action of the control arm and the positioning hole 21, the mounting surface 61 of the ball head pin is in a horizontal state, and the second through hole 62 is in a vertical state.

[0053] In this embodiment, preferably, two first support blocks 22 are symmetrically arranged.

[0054] The two first support blocks 22 cooperate with the left control arm and the right control arm respectively. When the left control arm is produced, the left control arm is placed in the control arm positioning mechanism 3 on the left side, and the first support block 22 on the left side is used to limit and support the control arm. When the right control arm is produced, the right control arm is placed in the control arm positioning mechanism 3 on the right side, and the first support block 22 on the right side is used to limit and support the control arm.

[0055] In this embodiment, preferably, the first positioning mechanism 2 further includes a second sensor 23, which is disposed on the worktable 1 and is used to detect whether the ball head pin is placed in place.

[0056] Before activating the pressure head 7, it is necessary to ensure that the ball head pin, fastening bolt, and control arm are all in place. A second sensor 23 is installed in the first positioning mechanism to detect whether the ball head pin is in position. Preferably, this second sensor 23 is a photoelectric sensor. If the ball head pin is in place, the second sensor 23 will receive a signal reflected by the ball head pin, thus issuing a signal indicating that the ball head pin is in position. The light emitted by the photoelectric sensor can only be reflected by the positioned ball head pin and will not be reflected by the control arm, thereby avoiding false activation of the photoelectric sensor.

[0057] In one embodiment, two photoelectric sensors are respectively set on both sides of the first positioning mechanism 2 to detect whether the ball head pin is placed in place during the production of the left control board and the right control arm.

[0058] Preferably, a second sensor 23 is provided, which is located near the first positioning mechanism 2. Since the ball head pin is in almost the same position near the positioning hole 21 during the production of both the left and right control arms, by detecting the ball head pin near the positioning hole 21, it is possible to use a photoelectric sensor to check the ball head pin during the production of the left and right control arms.

[0059] The photoelectric sensor is configured to detect ball joint pins near the positioning hole 21, ensuring that it can detect either the ball joint pin of the left or right control arm. Furthermore, the light emitted by the photoelectric sensor is not reflected by the control arm.

[0060] In this embodiment, preferably, the control arm positioning mechanism 3 includes a positioning pin 31 and a second support block 32.

[0061] The positioning pin 31 engages with the positioning hole 21 on the control arm. During the pressing process of the pressure head 7, the positioning pin 31 can prevent the control arm from moving. Preferably, the upper end of the positioning pin 31 is set to be conical. When the conical positioning pin 31 engages with the positioning hole 21 of the control arm, the control arm has a certain degree of freedom. When the fastening bolt 4 needs to be installed, the operator needs to adjust the relative position of the control arm and the ball head pin by shaking the fastening bolt 4 so that the fastening pin can pass through the control arm and the ball head pin at the same time and extend into the positioning hole 21 below.

[0062] The second support block 32 supports the two ends of the control arm away from the ball head pin, thereby adjusting the posture of the control arm on the worktable so that the first through hole 51 is in a vertical state at the position where the control arm is connected to the ball head pin. Therefore, during the pressing of the pressure head 7, the fastening bolt 4 can pass smoothly through the first through hole 51 on the control arm.

[0063] In this embodiment, preferably, the control arm positioning mechanism 3 includes a first sensor 33, which is used to detect whether the control arm is placed in the correct position.

[0064] Two first sensors 33 are provided, and the two first sensors 33 are used to detect the left control arm and the right control arm respectively.

[0065] The first sensor 33 and the second sensor 23 respectively detect whether the control arm and the ball head pin are in position. Only when the control arm and the ball head pin are in position are the pressure head 7 allowed to press down.

[0066] In this embodiment, preferably, the pressure head 7 is connected to the worktable 1 via a guide mechanism.

[0067] The guiding mechanism includes a fixed plate 11 and a linear guide rail 12. The fixed plate 11 is fixedly connected to the worktable 1. The fixed plate 11 is vertically arranged and the linear guide rail 12 is provided on the fixed plate 11. The pressure head 7 is slidably connected to the fixed plate 11 through the linear guide rail 12.

[0068] The linear guide 12 restricts the pressure head 7 from moving in a straight line in the vertical direction, thereby ensuring that the pressure head 7 can be aligned with the positioning hole 21 below each time it falls.

[0069] Preferably, at least two linear guide rails 12 are provided.

[0070] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0071] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0072] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
