Description

Technical Field

[0001] The utility model relates to the technical field of ball head assembly assembling equipment, in particular to a gasket assembling mechanism for a ball head assembly. Background Art

[0002] The automobile tie rod ball head is an important component in the automobile steering system. Its main function is to transmit steering force and buffer. Generally speaking, the two ends of the steering tie rod are respectively provided with ball head assemblies with different directions, and the main structure of the ball head assembly includes a ball head shell connected to the tie rod and a ball head body movably plugged into the ball head shell. The ball head body has a ball head pin extending to the outside of the ball head shell, and the free end of the ball head pin away from the ball head body is provided with an external thread, and the connection end of the ball head pin close to the ball head body needs to be equipped with a gasket.

[0003] Generally, the inner diameter of the gasket is larger than the outer diameter of the free end of the ball pin and equal to the outer diameter of the connecting end of the ball pin. Therefore, when the gasket is assembled on the ball pin, although it can pass through the free end of the ball pin relatively easily, it needs a large external force to be further installed on the connecting end of the ball end. However, since the ball head body and the ball head shell are movably connected, it is easy to misalign the gasket when it is installed on the connecting end of the ball pin by press-fitting, resulting in assembly failure. At the same time, the ball head body and the ball head shell will be under great pressure under press-fitting, which is prone to damage. Utility Model Content

[0004] The utility model aims to solve the problem in the prior art that when a ball stud and a gasket of a ball stud assembly are assembled, if a press-fitting method is adopted, the assembly is difficult and damage is easy to occur.

[0005] In order to solve the above problems, the utility model provides a gasket assembly mechanism for a ball head assembly, comprising:

[0006] The support platform is provided with a placing portion for placing the gasket, and the placing portion is provided with a vertical through hole for the ball stud to pass through;

[0007] A pre-pressing assembly, comprising a press platform and a pre-pressing driving member, wherein the press platform is located above the shelf portion, and an output end of the pre-pressing driving member is connected to the press platform and is used to drive the press platform to rise and fall;

[0008] The cam is provided with a screw hole, and the screw hole is arranged in a vertical direction, and the screw hole is arranged in a vertical direction, and is used for realizing the sleeve connection of the ball pin. The interior of the cam is provided with a accommodating cavity, and the upper part of the accommodating cavity is connected to the screw hole. The limit lever is arranged in a vertical direction, and the limit lever is slidably connected to the accommodating cavity along the vertical direction, and the limit lever can freely rotate relative to the accommodating cavity with the vertical axis as the axis. The accommodating cavity is provided with a spring acting on the limit lever, and the upper end of the limit lever is provided with a limit head, and the spring applies an upward thrust to the limit lever so that the limit head extends upward through the screw hole in a natural state, and the limit head is used to abut against the free end of the ball pin to realize the circumferential limit of the ball pin, and the pull-out driving member is used to drive the lifting and lowering of the cam or the rotation with the vertical axis as the axis.

[0009] When the pressing plate is pressed down and pressed to the upper side of the ball head assembly, the free end of the ball head pin will abut against the limiting head. Due to the upward thrust of the spring, the circumferential rotational friction resistance between the ball head pin and the ball head body and the ball head shell is large, so the ball head pin tends to remain circumferentially fixed; at this time, the pull-out drive member drives the pull-out table to rise while rotating, and the screw hole of the pull-out table will gradually move upward and be screwed with the ball head pin, and then the pull-out drive member drives the pull-out table to descend. Due to the screw connection between the screw hole and the ball head pin, the ball head pin will be driven downward, and the gasket of the resting part can be put on the connecting end position of the ball head pin, and finally the pull-out drive member drives the pull-out table to descend while rotating in the opposite direction, so that the ball head pin is disengaged from the screw hole, and the assembly of the ball head pin and the gasket can be completed. Compared with the prior art, the above scheme realizes circumferential limitation of the spherical pin by designing a pull-out assembly, and realizes circumferential limitation of the spherical pin through a limit lever of the pull-out assembly combined with a spring, and then screws the spherical pin with the screw hole of the pull-out table. When the pull-out table descends, the spherical pin can be moved in a downward pulling manner, so that the gasket is fitted to the connecting end position of the spherical pin, and the assembly of the spherical pin and the gasket is completed, thereby avoiding the misalignment problem of the spherical pin and the gasket in the traditional press-fitting method, or the damage problem of the spherical body and the spherical shell caused by excessive pressure.

[0010] In an improved embodiment, the support platform includes a base and a shelf, the base is fixed and a shelf groove is opened on the upper side of the base, the shelf is detachably connected to the shelf groove, and the shelf portion is located on the shelf, so that gaskets of different specifications and sizes can be adapted by replacing shelf plates with different shelf portions.

[0011] In an improved implementation scheme, the pull-out platform includes a receiving plate, a fixed sleeve, a screw sleeve head and a vertical transmission shaft, the output end of the pull-out drive acts on the transmission shaft, the receiving plate is connected to the upper end of the transmission shaft, the fixed sleeve is detachably connected to the upper side of the receiving plate, the screw sleeve head is located in the fixed sleeve, the upper part of the inner hole of the fixed sleeve is narrowed to achieve vertical limitation of the screw sleeve head, the receiving plate is provided with a positioning portion for circumferential limitation of the screw sleeve head, the screw hole is located at the upper part of the screw sleeve head, so that the receiving plate drives the screw sleeve head to rotate synchronously through the positioning portion, and the screw sleeve head with different screw holes can be replaced by removing the fixed sleeve, so as to achieve adaptation to spherical pins of different specifications and sizes, with good versatility and convenient disassembly and assembly.

[0012] In an improved embodiment, the accommodating cavity extends from the lower part of the screw sleeve head through the receiving plate to the upper part of the transmission shaft, and the lower end of the limit lever is provided with a guide column body, and the guide column body is vertically slidably connected to the accommodating cavity in the upper part of the transmission shaft; the spring is located in the accommodating cavity in the upper part of the transmission shaft and abuts against the guide column body, when the spring is in an extended state, the limit head of the limit lever passes through the screw hole to above the screw sleeve head, and when the spring is in a compressed state, the limit head of the limit lever retracts downward into the screw sleeve head. Since the limit lever is slidably connected to the accommodating cavity in the upper part of the transmission shaft through the guide column body at the lower end, replacing the screw sleeve head will not affect the limit lever.

[0013] In an improved implementation scheme, the upper part of the screw head is a conical structure that is small at the top and large at the bottom, and the lower side of the support platform is provided with a conical groove for the upper part of the screw head to adapt to. When the upper part of the screw head reaches the conical groove, it means that the threaded connection depth of the spherical pin and the screw hole meets the requirements. At this time, the pull-out drive can drive the pull-out platform to descend, so that the spherical pin is also driven to descend.

[0014] In an improved implementation scheme, the transmission shaft includes an upper shaft body and a lower shaft sleeve, the lower end of the upper shaft body is slidably inserted in the lower shaft sleeve, and the lower end of the upper shaft body is provided with a fastening bolt, and the side wall of the lower shaft sleeve is provided with an elongated hole with a vertical long edge, and the fastening bolt is cooperated and inserted into the elongated hole to control the telescopic position of the upper shaft body relative to the lower shaft sleeve, so that the telescopic position of the upper shaft body relative to the lower shaft sleeve can be controlled by the fastening bolt, thereby realizing the adjustment of the length of the transmission shaft.

[0028] The present application is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] See also Figure 1-Figure 6 , an embodiment of the utility model provides a gasket assembly mechanism for a ball head assembly, comprising:

[0030] The support platform 1 is provided with a placing portion 12a for placing the gasket, and the placing portion 12a is provided with a through hole 12b for the ball stud to pass through in the vertical direction;

[0031] The pre-pressing assembly 2 includes a press table 21 and a pre-pressing driving member 22. The press table 21 is located above the shelf portion 12a. The output end of the pre-pressing driving member 22 is connected to the press table 21 and is used to drive the press table 21 to rise and fall.

[0032] The pull-out assembly includes a pull-out platform 3, a limit lever 4 and a pull-out driving member 6. The pull-out platform 3 is located below the shelf portion 12a. A vertical screw hole 33a is provided on the upper side of the pull-out platform 3. The screw hole 33a is vertically arranged and used to realize the socket connection of the ball pin.

The limit lever 4 is vertically arranged, and the limit lever 4 is vertically slidably connected to the accommodating cavity 3a. It can rotate freely with the vertical axis relative to the accommodating chamber 3a. A spring 5 is arranged in the accommodating chamber 3a to act on the limit lever 4. A limit head 41 is arranged on the upper end of the limit lever 4. The spring 5 applies an upward thrust to the limit lever 4 so that the limit head 41 extends upward through the screw hole 33a in a natural state. The limit head 41 is used to abut against the free end of the spherical pin to achieve circumferential limitation of the spherical pin.

Due to the upward thrust of the spring 5, the circumferential rotational friction resistance between the ball head pin and the ball head body and the ball head shell is relatively large, so the ball head pin tends to remain The screw hole 33a of the pulling table 3 will gradually move upward and be screwed with the ball pin, and then the pulling drive member 6 will drive the pulling table 3 to descend. Due to the screw connection between the screw hole 33a and the ball pin, the ball pin will be driven downward. At this time, the gasket of the shelf portion 12a can be fitted to the connecting end position of the ball pin, and finally the pulling drive member 6 will drive the pulling table 3 to rotate in the opposite direction and descend, so that the ball pin is disengaged from the screw hole 33a, and the assembly of the ball pin and the gasket can be completed. Compared with the prior art, the above scheme realizes the circumferential limitation of the spherical pin by designing a pull-out assembly, and realizes the circumferential limitation of the spherical pin by the limit lever 4 of the pull-out assembly combined with the spring 5, and then screws the spherical pin with the screw hole 33a of the pull-out platform 3. When the pull-out platform 3 descends, the spherical pin can be moved in a downward pulling manner, so that the gasket is fitted to the connecting end position of the spherical pin, and the assembly of the spherical pin and the gasket is completed, thereby avoiding the misalignment problem of the spherical pin and the gasket in the traditional press-fitting method, or the damage problem of the spherical body and the spherical shell caused by excessive pressure.

The shelf portion 12a is a groove-shaped structure located on the shelf 12 for accurate placement of the gasket. After adopting the above structure, by replacing the shelf 12 with a different shelf portion 12a, gaskets of different specifications and sizes can be adapted.

[0035] In this embodiment, the pre-stressing drive member 22 is preferably a vertically arranged cylinder, the cylinder body of the pre-stressing drive member 22 is fixedly arranged and located above the support platform 1, the cylinder rod of the pre-stressing drive member 22 is arranged downward, and the pressing platform 21 is connected to the cylinder rod of the pre-stressing drive member 22.

[0036] In this embodiment, the rotary pull table 3 includes a receiving plate 31, a fixed sleeve 32, a screw sleeve head 33 and a transmission shaft 34 along the vertical direction. The output end of the rotary pull drive 6 acts on the transmission shaft 34. For the specific connection form of the rotary drive and the transmission shaft 34, please refer to the relevant content of the rotary pull drive 6 below, which will not be expanded here. The receiving plate 31 is connected to the upper end of the transmission shaft 34 and the two are coaxial, and the fixed sleeve 32 is detachably connected to the upper side of the receiving plate 31; the detachable connection between the fixed sleeve 32 and the receiving plate 31 in this embodiment is: the fixed sleeve 32 and the receiving plate 31 are both provided with screw holes 33a along the vertical direction and corresponding in position, and the detachable connection between the fixed sleeve 32 and the receiving plate 31 can be realized by screwing the screws to the screw holes 33a of the fixed sleeve 32 and the receiving plate 31; of course, the detachable connection between the fixed sleeve 32 and the receiving plate 31 can also be a common form in other prior arts, and this design does not limit this. The screw sleeve head 33 is located in the fixed sleeve 32, and the upper part of the inner hole of the fixed sleeve 32 is narrowed to realize the vertical limit of the screw sleeve head 33. The receiving plate 31 is provided with a positioning portion 31a for realizing circumferential limit of the screw sleeve head 33. In this embodiment, the positioning portion 31a is a plurality of plug keys distributed circumferentially on the upper side of the receiving plate 31, and the lower side of the screw sleeve head 33 is provided with key slots corresponding to the plug keys one by one, so as to realize the circumferential limit of the receiving plate 31 and the screw sleeve head 33, and facilitate the separation of the receiving plate 31 and the screw sleeve head 33.

When the spring 5 is in an extended state, the limit head 41 of the limit lever 4 passes through the screw hole 33a to the top of the screw sleeve head 33. When the spring 5 is in a compressed state, the limit head 41 of the limit lever 4 retracts downward into the screw sleeve head 33. Since the limit lever 4 is slidably connected to the accommodating chamber 3a at the upper part of the transmission shaft 34 through the guide column body 42 at the lower end, replacing the screw sleeve head 33 will not affect the limit lever 4. The shape of the limit head 41 can be designed according to the spherical pin. For example, if the end face of the free end of the spherical pin is a hexagonal hole, the limit head 41 of the limit lever 4 is a hexagonal head. When the hexagonal head is inserted into the hexagonal hole, the spherical pin is fixed circumferentially relative to the limit lever 4.

A conical groove 11b is provided on the lower side of the support platform 1 for the upper part of the screw head 33 to fit. When the upper part of the screw head 33 reaches the conical groove 11b, it means that the threaded connection depth between the spherical pin and the screw hole 33a meets the requirements. At this time, the pull-out drive 6 can drive the pull-out platform 3 to descend, so that the spherical pin is also driven to descend.

[0039] As an improvement to the transmission shaft 34, the transmission shaft 34 includes an upper shaft body 341 and a lower shaft sleeve 342.
