Description

Technical Field

[0001] The utility model relates to the technical field of automatic bolt tightening, in particular to a feeding guide for an automatic bolt tightening device. Background Art

[0002] An automatic bolt tightening device is a device used to connect two or more components together by bolts.

[0003] When the existing automatic bolt tightening device is in use, bolts are first placed into the feeding guide. Due to their own gravity and the guiding effect of the feeding guide, the connecting parts of the bolts are placed at a predetermined position above the connecting holes of the components to be connected, and the extending direction of the connecting parts faces the connecting holes of the components to be connected. Then, after a fastener of a collaborative robot extends into the feeding guide, the connecting parts of the bolts can be successfully threadedly connected to the connecting holes of the components to be connected, and finally the purpose of connecting the components to be connected is achieved.

[0004] Among them, the feeding guide of the existing automatic bolt tightening device includes a fixed member and two releasing members. The two releasing members are movably arranged on the fixed member. A space for passing bolts is formed between the two releasing members. The space formed between the two releasing members is in communication with the space inside the fixed member. The fixed member is fixed at a predetermined position of the disk group. After the bolts enter the space inside the fixed member, the bolts will fall into the space between the two releasing members due to their own gravity. Since the shape of the bolts is irregular, the postures of the bolts after entering the feeding guide are random. And because the two releasing members are movably arranged on the fixed member, there are gaps at the joints of the fixed member and the two releasing members. Therefore, one end of the bolt will abut against the gap and be stuck during the falling process.

[0005] Furthermore, since the operation steps of the automatic bolt tightening device when tightening bolts are set as fixed procedures, when the bolts are stuck and not discovered in time, the automatic bolt tightening device still executes the fixed procedures to extend the fastener into the fixed member and to a predetermined position inside the space between the two releasing members for rotation. At this time, the bolts will be driven by the fastener and rub against the inner walls of the fixed member and the two releasing members to generate metal particles, resulting in damage to the fixed member and the two releasing members and causing losses. The generated metal particles will also fall onto the components to be connected from the space between the two releasing members due to gravity, contaminating the components to be connected. And cleaning the contaminated components to be connected will also cause time loss. Summary of the Utility Model

[0031] Reference Figures 1 to 3 , according to a preferred embodiment of the present invention, the feeding and guiding member for a bolt automatic tightening device will be elaborated in detail below, wherein the feeding and guiding member for the bolt automatic tightening device includes a fixed member 10 and at least two release members 20.

[0032] The fixing member 10 includes a fixing guide 11 and a fixing piece 12. The fixing guide 11 is inserted through the fixing piece 12, and the fixing guide 11 is fixed to a disk set 92 through the fixing piece 12. The fixing guide 11 forms a feeding space 1101, and the feeding space 1101 is used for passing through a connecting piece 93. The connecting piece 93 enters the feeding space 1101 from the upper end of the feeding space 1101 with a connecting portion 931 of the connecting piece 93 facing downward. The extending direction of the feeding space 1101 of the fixing guide 11 faces a connecting hole 9401 of a member 94 to be connected. The fixing piece 12 has at least two resilient spaces 1201, and a pair of fixing shaft holes 1202 are formed at opposite positions on the side walls of the resilient spaces 1201.

[0033] The releasing member 20 includes a rotating member 21 and a releasing piece 22.

[0034] Specifically, the rotating member 21 is movably disposed in the resilient space 1201. The rotating member 21 has a rotating shaft hole 2101 corresponding to the pair of fixing shaft holes 1202, and the movement of the rotating member 21 is realized by a shaft rod passing through the rotating shaft hole 2101 and the pair of fixing shaft holes 1202. That is to say, the rotating member 21 is movably disposed on the fixing piece 12 through the shaft rod.

[0035] The releasing piece 22 includes a releasing insertion portion 221, an anti-jamming portion 222, and a releasing guide portion 223.

[0036] In this embodiment, the releasing insertion portion 221 is connected to the rotating member 21.

[0037] In a variant embodiment, the anti-jamming portion 222 is connected to the rotating member 21.

[0038] In another variant embodiment, the releasing guide portion 223 is connected to the rotating member 21.

[0039] To enable those skilled in the art to understand the present invention, in at least one embodiment of the present invention, only the example where the releasing insertion portion 221 is connected to the rotating member 21 is described.

[0040] Specifically, the releasing guide portion 223 is connected to the releasing insertion portion 221 through the anti-jamming portion 222.

[0041] A connection space 22101 is formed between the release insertion portions 221 of the release members 22 of at least two of the release members 20. The fixed guide 11 has an insertion end 111. After the rotating member 21 is movably disposed on the fixing member 12 through the shaft, the insertion end 111 of the fixed guide 11 will be disposed in the connection space 22101.

[0042] An anti-jamming space 22201 is formed between the anti-jamming portions 222 of the release members 22 of at least two of the release members 20. After the insertion end 111 of the fixed guide 11 is disposed in the connection space 22101, the upper end portion of the anti-jamming space 22201 will communicate with the lower end portion of the feeding space 1101.

[0043] A release space 22301 communicating with the anti-jamming space 22201, a limiting space 22302 communicating with the release space 22301, and a release guiding space 22303 communicating with the limiting space 22302 are formed between the release guiding portions 223 of the release members 22 of at least two of the release members 20.

[0044] It should be noted that since the rotating member 21 is movably disposed on the fixing member 12 through the shaft, there is a gap between the anti-jamming portion 222 of the release member 22 and the insertion end 111 of the fixed guide 11. When the connecting member 93 enters the release space 22301 from the lower end portion of the feeding space 1101 through the anti-jamming space 22201, the attitude of the connecting member 93 falling under the action of gravity is random, and further, a driving portion 932 and a connecting portion 931 of the connecting member 93 will enter and be stuck in the gap between the anti-jamming portion 222 and the insertion end 111.

[0045] Preferably, the inner diameter of the upper end portion to the lower end portion of the anti-jamming space 22201 gradually decreases and forms a sliding surface 22202, so that after the insertion end 111 of the fixed guide 11 is disposed in the connection space 22101, when the connecting portion 931 and the driving portion 932 of the connecting member 93 falling under the action of gravity enter the gap between the anti-jamming portion 222 and the insertion end 111, they will abut against the surface of the sliding surface 22202 and fall into the release space 22301 under the action of the sliding surface 22202.

[0046] It is worth mentioning that the inner diameter of the upper end of the anti-jamming space 22201 is smaller than the inner diameter of the connection space 22101, so that after the insertion end 111 of the fixed guide member 11 is arranged in the connection space 22101, the insertion end 111 will be prevented from moving due to abutting against the upper end of the anti-jamming part 222. The inner diameter of the release space 22301 is the same as the inner diameter of the lower end of the anti-jamming space 22201, so that the connecting member 93 can smoothly enter the release space 22301 after passing through the anti-jamming space 22201.

[0047] Specifically, the inner diameter of the upper end to the lower end of the limiting space 22302 gradually decreases. The inner diameter of the upper end of the limiting space 22302 is the same as the inner diameter of the release space 22301 and is larger than the outer diameter of the driving part 932. The inner diameter of the release guiding space 22303 is the same as the inner diameter of the lower end of the limiting space 22302 and is larger than the outer diameter of the connecting part 931.

[0048] Preferably, the feeding guide member for the bolt automatic tightening device further includes a plurality of resilient members 30. At least one of the resilient members 30 is arranged between the rotating member 21 and the fixing member 12 in a compressible manner, and the resilient member 30 is used to restore the position of the rotating member 21 relative to the fixing member 12 after the rotating member 21 rotates relative to the fixing member 12 through the shaft rod.

[0049] Specifically, a fixing groove matching the resilient member 30 is formed on the facing surfaces of the fixing member 12 and the rotating member 21, and both ends of the resilient member 30 are arranged in the fixing groove formed on the facing surfaces of the fixing member 12 and the rotating member 21 to prevent the resilient member 30 from sliding between the fixing member 12 and the rotating member 21.

[0050] As an example, the fixing groove formed on the surface of the fixing member 12 is located above the fixing shaft hole 1202, and the fixing groove formed on the surface of the rotating member 21 is located above the rotating shaft hole 2101. In other words, the resilient member 30 is located above the shaft rod.

[0051] In a modified embodiment, the fixing groove formed on the surface of the fixing member 12 is located below the fixing shaft hole 1202, and the fixing groove formed on the surface of the rotating member 21 is located below the rotating shaft hole 2101. In other words, the resilient member 30 is located below the shaft rod.

[0052] Preferably, the resilient member 30 is implemented to include a spring.

[0053] To enable those skilled in the art to understand the present utility model, in at least one embodiment of the present utility model, only the fixing groove formed on the surface of the fixing member 12 is located below the fixing shaft hole 1202, and the fixing groove formed on the surface of the rotating member 21 is located below the rotating shaft hole 2101 as an example for elaboration.

[0054] It should be noted that the driving portion 932 of the connecting member 93 has a rotating groove matching with a fastening end 911 of a fastening member 91, so as to facilitate the fastening end 911 to drive the driving portion 932 to rotate, and threadedly connect the connecting portion 931 to the inner wall of the connecting hole 9401 of the member to be connected 94 through the rotation of the driving portion 932.

[0055] As Figures 4A to 4D shown, those skilled in the art should understand that when the connecting member 93 enters the feeding space 1101 from the upper end of the feeding space 1101 under the action of gravity, the driving portion 932 of the connecting member 93 will sequentially pass through the feeding space 1101, the anti - jamming space 22201 and the release space 22301 and reach the limiting space 22302, and the connecting portion 931 will enter the release guiding space 22303. At this time, control the fastening member 91 so that the fastening end 911 of the fastening member 91 sequentially passes through the feeding space 1101, the anti - jamming space 22201 and the release space 22301 and then reaches the limiting space 22302, and make the fastening end 911 of the fastening member 91 extend into the rotating groove of the driving portion 932, press the driving portion 932 of the connecting member 93 towards the release guiding space 22303, and make the edge of the driving portion 932 abut against the side wall of the limiting space 22302.

[0056] Furthermore, since the inner diameter of the upper end to the lower end of the limiting space 22302 gradually decreases, and the rotating member 21 connected to the release member 22 is movably arranged on the fixing member 12 through the shaft rod, during the process that the fastening end 911 presses the driving portion 932 downward, the driving portion 932 will gradually expand the inner diameters of the limiting space 22302 and the release guiding space 22303, so as to facilitate the driving portion 932 to enter the release guiding space 22303, and make the connecting portion 931 enter the connecting hole 9401 of the member to be connected 94, and threadedly connect the connecting portion 931 of the connecting member 93 to the inner wall of the connecting hole 9401 through the rotation of the fastening member 91 by the fastening end 911.

[0057] It is worth mentioning that, during the process that the driving part 932 gradually expands the inner diameters of the limiting space 22302 and the release guiding space 22303, the rotating part 21 will rotate around the shaft rod and compress the resilient member 30. When the driving part 932 of the connecting member 93 enters the release guiding space 22303 under the pressing of the fastening end 911, the release guiding parts 223 of the release pieces 22 of at least two release members 20 will press against the driving part 932 under the resilient action of the resilient member 30 to prevent the driving part 932 from falling out of the release guiding space 22303.

[0058] During the process that the connecting part 931 of the connecting member 93 is threadedly connected to the inner wall of the connecting hole 9401 through the fastening end 911 under the rotation of the fastener 91, the fastening end 911 of the fastener 91 will enter and pass through the limiting space 22302, and the release guiding parts 223 of the release pieces 22 of at least two release members 20 will press against the fastener 91 under the resilient action of the resilient member 30.

[0059] Furthermore, after the connecting part 931 of the connecting member 93 is threadedly connected to the inner wall of the connecting hole 9401, the fastening end 911 of the fastener 91 will separate from the rotating groove of the driving part 932, and sequentially pass through the release guiding space 22303, the limiting space 22302, the release space 22301, the anti-jamming space 22201 and the feeding space 1101, so that the fastening end 911 of the fastener 91 is far away from the feeding space 1101 to wait for the next connecting member 93 to enter the feeding space 1101.

[0060] It is worth mentioning that, under the resilient action of the resilient member 30, the inner diameters of the limiting space 22302 and the release guiding space 22303 will return to their original sizes.

[0061] In this embodiment, the inner diameter of the upper end to the lower end of the feeding space 1101 gradually decreases, so that when the connecting member 93 entering the feeding space 1101 enters and passes through the feeding space 1101 under the action of gravity, skewing can be avoided.

[0062] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been shown and described in the embodiments. Without departing from the above principles, the embodiments of the present invention can have any deformation or modification.
