For the purpose of illustration, the drawings show only the structures associated with embodiments of the utility model.

Referring to the drawings, in one embodiment, the tie rod ball disassembling tool 100 provided by the present application includes a base 10, a positioning assembly 20 and an ejector 30. Specifically, the tie rod ball disassembling tool 100 of the present application can be applied to disassembling the tie rod ball 200.

As shown in fig. 1 and fig. 2, the base 10 has a supporting plane 11 and a separating channel 12 penetrating through the supporting plane 11, the supporting plane 11 is convexly provided with a connecting portion 111, the separating channel 12 can be clamped with the drawbar ball 200, the positioning assembly 20 includes a positioning member 21 and a connecting member 22 connected to the positioning member 21, the positioning member 21 is disposed opposite to the supporting plane 11, one end of the connecting member 22 protrudes out of the positioning member 21 to be connected to the connecting portion 111, and the ejecting member 30 is positioned at the positioning member 21 and is operable to move relative to the positioning member 21 to provide an acting force for ejecting the drawbar ball 200 out of the separating channel 12. Specifically, one end of the connecting member 22 is provided with a limiting groove, and the connecting portion 111 protrudes into the limiting groove to connect with the connecting member 22.

It should be noted that the base 10 in the embodiment of the present application can be fixedly attached to the test stand. Specifically, the base 10 is a fixing jig. Preferably, the base 10 is in the shape of a disc and the escape passage 12 is a through hole in the center of the disc. Thus, the disk-shaped base 10 is strong in adaptability, does not have edges and edges, and can avoid damage to other components in the process of using the pull rod ball head to disassemble the tool 100.

Therefore, the connecting part 111 is arranged on the base 10 in a protruding mode and connected with the connecting piece 22, and a threaded hole is prevented from being tapped in the base 10, so that the bearing capacity of the base 10 is improved, and the bearing capacity of the pull rod ball head dismounting tool 100 is further improved.

Further, the connection portion 111 has a first thread portion, the limit groove has a second thread portion, and the connection portion 111 and the limit groove are in threaded connection with the second thread portion through the first thread portion. So, base 10 and connecting piece 22 can be through connecting portion 111 and the fixed linking to each other of spacing groove, avoid dismantling frock 100 at the pull rod bulb in the use, connecting piece 22 takes place relative slip with base 10, cause can't provide the holding power that leans on steadily for ejecting 30. Preferably, the connection portion 111 is a bolt. In other embodiments, the first threaded portion may be disposed outside the connecting member 22, and the connecting portion 111 may be a bolt sleeve having a second threaded portion, so that the connecting portion 111 is threadedly coupled to the connecting member 22.

In some embodiments, the connection portion 111 includes at least two sub-connection portions 1111, the at least two sub-connection portions 1111 are spaced apart from each other around the escape passage 12, the connection member 22 includes at least two sub-connection members 222, and the at least two sub-connection members 222 are connected to the at least two sub-connection portions 1111 in a one-to-one correspondence. In this way, the positioning member 21 can be balanced without tilting, thereby providing a reliable supporting force for the ejector 30 to move in the guide hole 211 in the first direction.

In the embodiment of the present application, the connection portion 111 includes two sub-connection portions 1111, the two sub-connection portions 1111 are disposed at two sides of the separation channel 12, and the connection member 22 includes two sub-connection members 222, and the two sub-connection members 222 are connected to the two sub-connection portions 1111 in a one-to-one correspondence manner. In this way, the two sub-connectors 222 disposed oppositely can provide balanced acting force for the positioning member 21, thereby ensuring that the ejector 30 can move in the guide hole 211 along the first direction while saving material and simplifying the structure. Preferably, the connector 22 is a screw.

Furthermore, the positioning element 21 is provided with at least two adjusting holes 212, each sub-connecting element 222 can respectively penetrate through a corresponding adjusting hole 212, and each sub-connecting element 222 can operatively move in the corresponding adjusting hole 212. Since the base 10 has different sizes in practical applications, the position of the connecting portion 111 relative to the separation channel 12, that is, the position of the connecting portion 111 on the base 10, can be changed, and by providing the adjusting hole 212, each sub-connecting member 222 can move in the adjusting hole 212, so as to adapt to the positions of different connecting portions 111 on the base 10, thereby improving the versatility of the tie rod ball head dismounting device 100. In particular, in the present embodiment, the adjustment hole 212 is a kidney-shaped hole. More specifically, the adjusting hole 212 includes two sub-adjusting holes through which the two sub-connecting members 222 can be respectively inserted.

Thus, the limiting shoulder 221 can provide stable supporting force for the positioning element 21, and limit the positioning element 21, so that the positioning element 21 is prevented from moving along with the ejector 30 in the guide hole 211 in the use process of the pull rod ball head dismounting tool 100, and reliable supporting force cannot be provided for the ejector 30. Specifically, the connector 22 includes a connector segment 223 and a connector sleeve segment 224, the connector segment 223 having a diameter smaller than the diameter of the connector sleeve segment 224 such that a stop shoulder 221 is formed at the junction of the connector segment 223 and the connector sleeve segment 224.

Further, the positioning assembly 20 further comprises a locking member 23, wherein the locking member 23 can cooperate with the connecting member 22 to lock the connecting member 22 to the positioning member 21. Thus, the locking member 23 can reliably fix the connecting member 22 to the positioning member 21, so as to prevent the connecting member 22 from sliding relative to the positioning member 21 during the process of ejecting the tie rod ball 200, thereby reliably fixing the connecting member 22 and the positioning member 21.

Furthermore, the connecting member 22 is disposed through the positioning member 21, so that the positioning member 21 is supported on the limiting shoulder 221, and the locking member 23 is engaged with the connecting member 22 at a side of the positioning member 21 away from the limiting shoulder 221, and abuts against the positioning member 21, so as to lock the connecting member 22 to the positioning member 21. Specifically, the locking member 23 is a nut, and the connecting member 22 has a first threaded portion capable of being engaged with the threads of the locking member 23. More specifically, the connecting rod segment 223 has a first threaded portion. Of course, in other embodiments, other assembling methods that can reliably fix the connecting member 22 to the positioning member 21 may be adopted.

In some embodiments, the positioning member 21 defines a guide hole 211, and the ejector 30 is disposed through the guide hole 211. The guide hole 211 is provided to guide the ejector 30 to move, thereby reliably ejecting the tie rod ball 200. More specifically, the central axis of the guide hole 211 coincides with the central axis of the escape passage.

Further, the ejector 30 has a third thread portion, the guide hole 211 has a fourth thread portion, and the ejector 30 can be inserted into the guide hole 211 and is in threaded connection with the guide hole 211 through the third thread portion and the fourth thread portion. In this way, the ejector 30 can be stably and reliably screwed in from the guide hole 211 through the cooperation of the third threaded portion and the fourth threaded portion, so as to apply a continuous and stable pressure to the tie rod ball 200 until the tie rod ball is separated from the base 10.

As shown in fig. 3, in the embodiment of the present application, the end of the ejector 30 that abuts against the tie rod ball 200 has a tapered portion 31 so that the urging force applied to the tie rod ball 200 by the ejector 30 can be concentrated on a point at which the ejector 30 abuts against the tie rod ball 200. Specifically, the ejector 30 is a bolt.
