Description

Technical Field

[0001] This utility model belongs to the field of support tool technology, specifically relating to an auxiliary support device for double-forked ear assembly parts. Background Technology

[0002] In daily production, bushings or bearings need to be installed on double-fork lug assemblies. This requires support between the two lugs to prevent damage during installation. Currently, a single support block is used, but to facilitate installation, the block's dimensions are slightly smaller than the distance between the lugs. This results in insufficient support strength and fails to provide adequate protection. With increasingly stringent assembly quality requirements, the current method is no longer sufficient. Therefore, a support device that can adapt to the height difference between the two lugs is needed. Utility Model Content

[0003] The purpose of this invention is to provide an auxiliary support device for double-forked lug assemblies, solving the problem of insufficient support strength of existing support blocks.

[0004] The technical solution adopted by this utility model is an auxiliary support device for double-ear type fittings, including a hollow support member, a spiral fine-tuning member threadedly connected to the inner wall of the support member, an upper plate sleeved on the outer wall of the support member, a rotating sliding member threadedly connected to the outer wall of the support member and below the upper plate, a bottom plate sleeved on the bottom of the rotating sliding member, and the bottom plate connected to the upper plate. The features of this utility model also include: The support includes a regular hexagonal body with a fourth threaded through hole and a second adjusting block connected to the bottom of the regular hexagonal body.

[0005] The hexagonal body, the fourth threaded through hole, and the second adjusting block are coaxially arranged.

[0006] The spiral fine-tuning component includes a top support block, the bottom of which is connected to a first adjusting block, and the outer wall of the first adjusting block is threadedly connected to the inner wall of the fourth threaded through hole.

[0007] The top support block is coaxially arranged with the first adjusting block, and the diameter of the top support block is not less than the diameter of the first adjusting block.

[0008] The upper plate includes an upper plate body, which has an internal hexagonal through hole. A protrusion is connected to the side wall of the upper plate body, and a number of first threaded through holes are provided on the protrusion. A regular hexagonal body is embedded in the internal hexagonal through hole.

[0009] The center of the internal hexagonal through hole coincides with the center of the upper plate body, and the thickness of the protrusion is the sum of the thickness of the upper plate body and the thickness of the rotating sliding part.

[0010] The base plate includes a base plate body, the top of which is provided with a groove, the base plate body and the groove are coaxially arranged, a first handle is connected to the side wall of the base plate body, the first handle is provided with a number of second threaded through holes, the number of second threaded through holes is equal to the number of first threaded through holes and they correspond one-to-one, the number of second threaded through holes and the number of first threaded through holes are connected by bolt threads.

[0011] The rotating slider includes a sliding body with a third threaded through hole, a second handle connected to the side wall of the sliding body, a boss connected to the bottom of the sliding body, the third threaded through hole being threadedly connected to the outer wall of the second adjusting block, and the boss being embedded in the groove.

[0012] The boss and the sliding body are coaxially arranged, and the diameter of the boss is not greater than the diameter of the sliding body.

[0013] The beneficial effects of this utility model are: (1) This utility model is used for an auxiliary support device for double-fork lug assemblies. By adjusting the height of the spiral fine-tuning part, the support height can be initially adjusted so that the height is close to the distance between the two forks in the double-fork lug assembly. Then, by adjusting the height of the support part, the upper surface of the spiral fine-tuning part contacts the bottom of the upper fork lug, so that the entire auxiliary support device can fully contact the two forks lugs. The height meets the distance requirement between the two forks lugs and provides full support, avoiding the problem of insufficient support force. In addition, the support height of this device is easy to adjust and easy to operate. During the batch installation of the same product, the height can be adjusted by rotating the second handle, and the spiral fine-tuning part can remain stationary, which greatly improves the work efficiency.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments.

[0016] Example 1 This utility model relates to an auxiliary support device for double-forked lug assembly parts, the structure of which is as follows: Figure 1 As shown, the support includes a hollow support member 5. A screw-adjusting component 1 is threadedly connected to the inner wall of the support member 5. The screw-adjusting component 1 can move axially up and down relative to the support member 5. An upper plate 2 is sleeved on the outer wall of the support member 5. The upper plate 2 is used to prevent the support member 5 from rotating, so that the support member 5 can only move axially up and down. A rotating sliding component 4 is threadedly connected to the outer wall of the support member 5 and located below the upper plate 2. The rotating sliding component 4 can make the support member 5 move up and down. A bottom plate 3 is sleeved on the bottom of the rotating sliding component 4. The bottom plate 3 is used to make the rotating sliding component 4 only move in a circle around the axis of the bottom plate 3. The bottom plate 3 is connected to the upper plate 2.

[0017] The working process of this auxiliary support device for double-fork lug assemblies is as follows: First, rotate and adjust the screw fine-tuning part 1 so that the dimension between the upper surface of the screw fine-tuning part 1 and the bottom of the base plate 3 is close to the dimension between the two forks. Then, place the entire auxiliary support device between the two forks and place the bottom of the base plate 3 on the lower fork. By rotating the rotating sliding part 4, the support part 5 moves upward along the axis until the upper surface of the screw fine-tuning part 1 contacts the lower surface of the upper fork. Thus, bushings or bearings can be installed on the double-fork lug assemblies. The auxiliary support device supports the double forks. In the mass production of the same product, after one adjustment, it is not necessary to repeatedly adjust the screw fine-tuning part 1. Simply rotate the rotating sliding part 4 in the opposite direction to lower the height of the auxiliary support device and release the support. Then, by rotating the rotating sliding part 4 in the initial rotation direction, the support can be quickly restored.

[0018] Example 2 This utility model relates to an auxiliary support device for double-forked lug assembly parts, the structure of which is as follows: Figure 1 As shown, the support includes a hollow support member 5. A screw-adjusting component 1 is threadedly connected to the inner wall of the support member 5. The screw-adjusting component 1 can move axially up and down relative to the support member 5. An upper plate 2 is sleeved on the outer wall of the support member 5. The upper plate 2 is used to prevent the support member 5 from rotating, so that the support member 5 can only move axially up and down. A rotating sliding component 4 is threadedly connected to the outer wall of the support member 5 and located below the upper plate 2. The rotating sliding component 4 can make the support member 5 move up and down. A bottom plate 3 is sleeved on the bottom of the rotating sliding component 4.

[0019] like Figure 2 and Figure 3 As shown, the support member 5 includes a regular hexagonal body 51, on which a fourth threaded through hole 53 is provided. The fourth threaded through hole 53 is used to connect the spiral fine-tuning member 1, so that the spiral fine-tuning member 1 can move axially up and down by rotating the thread, thereby adjusting the height. The bottom of the regular hexagonal body 51 is connected to a second adjusting block 52. The regular hexagonal body 51, the fourth threaded through hole 53, and the second adjusting block 52 are coaxially arranged, which makes the stability and adaptability higher. The regular hexagonal body 51 cooperates with the upper plate 2 to limit and prevent the support member 5 from moving in a circle around the axis. The second adjusting block 52 is used to be threadedly connected to the rotating sliding member 4. By rotating the rotating sliding member 4 and under the limitation of the upper plate 2, the support member 5 can only move axially up and down, thereby realizing the height adjustment.

[0020] The working process of this auxiliary support device for double-fork lug assemblies is as follows: First, rotate the adjusting screw fine-tuning part 1 so that the dimension between the upper surface of the screw fine-tuning part 1 and the bottom of the base plate 3 is close to the dimension between the two forks. Then, place the entire auxiliary support device between the two forks and place the bottom of the base plate 3 on the lower fork. Rotate the rotating sliding part 4 to make the second adjusting block 52 move upward along the axis. The second adjusting block 52 drives the regular hexagonal body 51 to move upward, thereby driving the screw fine-tuning part 1 to move upward, so that the upper surface of the screw fine-tuning part 1 contacts the lower surface of the upper fork. Thus, bushings or bearings can be installed on the double-fork lug assemblies. The auxiliary support device supports the double forks. In the mass production process of the same product, after one adjustment, it is not necessary to repeatedly adjust the screw fine-tuning part 1. Simply rotate the rotating sliding part 4 in the opposite direction to lower the height of the auxiliary support device and release the support. Then, by rotating the rotating sliding part 4 in the initial rotation direction, the support can be quickly restored.

[0021] Example 3 This utility model relates to an auxiliary support device for double-forked lug assembly parts, the structure of which is as follows: Figure 1 As shown, the support includes a hollow support member 5. A screw-adjusting component 1 is threadedly connected to the inner wall of the support member 5. The screw-adjusting component 1 can move axially up and down relative to the support member 5. An upper plate 2 is sleeved on the outer wall of the support member 5. The upper plate 2 is used to prevent the support member 5 from rotating, so that the support member 5 can only move axially up and down.

The regular hexagonal body 51, the fourth threaded through hole 53, and the second adjusting block 52 are coaxially arranged, which makes the stability and adaptability higher. The regular hexagonal body 51 cooperates with the upper plate 2 to limit and prevent the support member 5 from making circular motion around the axis. The second adjusting block 52 is used to be threadedly connected to the rotating sliding member 4. By rotating the rotating sliding member 4 and under the limitation of the upper plate 2, the support member 5 can only make axial up and down movements, thereby realizing height adjustment.

[0023] like Figure 4 and Figure 5As shown, the spiral fine-tuning component 1 includes a top support block 11, and a first adjusting block 12 is connected to the bottom of the top support block 11. The outer wall of the first adjusting block 12 is threadedly connected to the inner wall of the fourth threaded through hole 53. By rotating the spiral fine-tuning component 1, the spiral fine-tuning component 1 moves axially up and down through the thread rotation, thereby adjusting the height.

[0024] The top support block 11 is coaxially arranged with the first adjusting block 12. The diameter of the top support block 11 is not less than the diameter of the first adjusting block 12, which can increase the contact area with the upper fork lug and improve the support effect.

[0025] The working process of this auxiliary support device for double-fork lug assemblies is as follows: First, rotate the top support block 11 of the adjusting screw fine-tuning part 1. The top support block 11 drives the first adjusting block 12 to move upward along the thread of the fourth threaded through hole 53, so that the dimension between the upper surface of the top support block 11 and the bottom of the base plate 3 is close to the dimension between the two forks. Then, place the entire auxiliary support device between the two forks and place the bottom of the base plate 3 on the lower fork. By rotating the rotating sliding part 4, the second adjusting block 52 moves upward along the axial direction. The second adjusting block 52 carries... The movable hexagonal body 51 moves upward, thereby driving the spiral fine-tuning component 1 to move upward, so that the upper surface of the top support block 11 contacts the lower surface of the fork lug located above it. This allows for the installation of bushings or bearings on double fork lug assemblies. The auxiliary support device supports the double fork lugs. During the batch production of the same product, after one adjustment, there is no need to repeatedly adjust the spiral fine-tuning component 1. Simply rotate the rotating slider 4 in the opposite direction to lower the height of the auxiliary support device, release the support, and then quickly restore the support by rotating the rotating slider 4 in the initial rotation direction.

[0026] Example 4 This utility model relates to an auxiliary support device for double-forked lug assembly parts, the structure of which is as follows: Figure 1 As shown, the support includes a hollow support member 5. A screw-adjusting component 1 is threadedly connected to the inner wall of the support member 5. The screw-adjusting component 1 can move axially up and down relative to the support member 5. An upper plate 2 is sleeved on the outer wall of the support member 5. The upper plate 2 is used to prevent the support member 5 from rotating, so that the support member 5 can only move axially up and down. A rotating sliding component 4 is threadedly connected to the outer wall of the support member 5 and located below the upper plate 2. The rotating sliding component 4 can make the support member 5 move up and down. A bottom plate 3 is sleeved on the bottom of the rotating sliding component 4. The bottom plate 3 is used to make the rotating sliding component 4 only move in a circle around the axis of the bottom plate 3. The bottom plate 3 is connected to the upper plate 2.

By rotating the rotating sliding member 4 and under the limitation of the upper plate 2, the support member 5 can only make axial up and down movements, thereby realizing height adjustment.

[0028] like Figure 4 and Figure 5 As shown, the spiral fine-tuning component 1 includes a top support block 11, and a first adjusting block 12 is connected to the bottom of the top support block 11. The top support block 11 and the first adjusting block 12 are coaxially arranged. The diameter of the top support block 11 is not less than the diameter of the first adjusting block 12, which can increase the contact area with the upper fork lug and improve the support effect. The outer wall of the first adjusting block 12 is threadedly connected to the inner wall of the fourth threaded through hole 53. By rotating the spiral fine-tuning component 1, the spiral fine-tuning component 1 moves axially up and down through the thread rotation, thereby adjusting the height.

[0029] like Figure 6 and Figure 7 As shown, the upper plate 2 includes an upper plate body 21, on which an internal hexagonal through hole 24 is provided. A regular hexagonal body 51 is embedded in the internal hexagonal through hole 24. Through the cooperation between the internal hexagonal through hole 24 and the regular hexagonal body 51, the internal hexagonal through hole 24 is limited in the circumferential direction along the axis, so that it can only move up and down in the axial direction and cannot move in the circle. A protrusion 22 is connected to the side wall of the upper plate body 21. A plurality of first threaded through holes 23 are provided on the protrusion 22. The protrusion 22 is used to connect and fix with the bottom plate 3.

[0030] The center of the internal hexagonal through hole 24 coincides with the center of the upper plate body 21. The thickness of the protrusion 22 is the sum of the thickness of the upper plate body 21 and the thickness of the rotating sliding member 4, thereby ensuring that the bottom of the protrusion 22 contacts the bottom plate 3 for fixation.

[0031] The working process of this auxiliary support device for double-fork lug assemblies is as follows: First, rotate the top support block 11 of the adjusting screw fine-tuning part 1.

The auxiliary support device supports the double fork lug. In the process of mass production of the same product, after one adjustment, there is no need to repeatedly adjust spiral fine-tuning component 1. Simply rotate the rotating slider 4 in the opposite direction to lower the height of the auxiliary support device, release the support, and then quickly restore support by rotating the rotating slider 4 in the initial rotation direction.

The regular hexagonal body 51, the fourth threaded through hole 53, and the second adjusting block 52 are coaxially arranged, which makes the stability and adaptability higher. The regular hexagonal body 51 cooperates with the upper plate 2 to limit and prevent the support member 5 from making circular motion around the axis. The second adjusting block 52 is used to be threadedly connected to the rotating sliding member 4. By rotating the rotating sliding member 4 and under the limitation of the upper plate 2, the support member 5 can only make axial up and down movements, thereby realizing height adjustment.

[0034] like Figure 4 and Figure 5As shown, the spiral fine-tuning component 1 includes a top support block 11, and a first adjusting block 12 is connected to the bottom of the top support block 11. The top support block 11 and the first adjusting block 12 are coaxially arranged.

A protrusion 22 is connected to the side wall of the upper plate body 21, and a plurality of first threaded through holes 23 are provided on the protrusion 22.

[0036] The center of the internal hexagonal through hole 24 coincides with the center of the upper plate body 21.

The plurality of second threaded through holes 33 and the plurality of first threaded through holes 23 are connected by bolt threads.

[0038] The working process of the auxiliary support device for double-fork lug assembly of this utility model is as follows: First, rotate the top support block 11 of the adjusting screw fine-tuning part 1. The top support block 11 drives the first adjusting block 12 to move upward along the thread of the fourth threaded through hole 53, so that the dimension between the upper surface of the top support block 11 and the bottom of the base plate 3 is close to the dimension between the two forks. Then, place the entire auxiliary support device between the two forks and place the bottom of the base plate body 31 on the lower fork. Under the limitation of the groove 34, the rotating sliding part 4 can only move circumferentially. Under the limitation of the upper plate body 21, the support part 5 can only move axially up and down. Therefore, by rotating... The sliding member 4 causes the second adjusting block 52 to move upward along the axial direction. The second adjusting block 52 drives the regular hexagonal body 51 to move upward, thereby driving the spiral fine-tuning member 1 to move upward, so that the upper surface of the top support block 11 contacts the lower surface of the fork lug located above. This allows bushings or bearings to be installed on double fork lug assemblies. The auxiliary support device supports the double fork lug. In the process of mass production of the same product, after one adjustment, there is no need to repeatedly adjust the spiral fine-tuning member 1. Simply rotate the sliding member 4 in the opposite direction to lower the height of the auxiliary support device, release the support, and then quickly restore the support by rotating the sliding member 4 in the initial rotation direction.

The plurality of second threaded through holes 33 and the plurality of first threaded through holes 23 are connected by bolt threads.

[0045] like Figure 10 and Figure 11As shown, the rotating slider 4 includes a sliding body 41, on which a third threaded through hole 43 is provided. A second handle 42 is connected to the side wall of the sliding body 41. The second handle 42 is used for hand gripping, which facilitates the application of force to rotate the sliding body 41. A boss 44 is connected to the bottom of the sliding body 41. The boss 44 is coaxially arranged with the sliding body 41. The diameter of the boss 44 is smaller than the diameter of the sliding body 41. The third threaded through hole 43 is threadedly connected to the outer wall of the second adjusting block 52. The boss 44 is embedded in the groove 34. Through the cooperation between the boss 44 and the groove 34, the boss 41 can only make circumferential movements within the groove 34, thereby ensuring that the sliding body 41 makes circumferential movements. The outer diameter of the upper plate body 21 is equal to that of the sliding body 41. Therefore, the protrusion 22 is also located on the outside of the sliding body 41 and will not be blocked by the sliding body 41, so that it can be connected and fixed with the first handle 32.

[0046] The working process of the auxiliary support device for double-fork lug assembly of this utility model is as follows: First, rotate the top support block 11 of the adjusting screw fine-tuning part 1. The top support block 11 drives the first adjusting block 12 to move upward along the thread of the fourth threaded through hole 53, so that the dimension between the upper surface of the top support block 11 and the bottom of the base plate 3 is close to the dimension between the two forks. Then, place the entire auxiliary support device between the two forks and place the bottom of the base plate body 31 on the lower fork. Under the limitation of the groove 34, the rotating sliding part 4 can only move circumferentially. Under the limitation of the upper plate body 21, the support part 5 can only move axially up and down. Then, by rotating the second handle 42, the device can be driven to move upward. The sliding body 41 rotates, causing the second adjusting block 52 to move upward along the axis. The second adjusting block 52 drives the regular hexagonal body 51 to move upward, thereby driving the spiral fine-tuning component 1 to move upward, so that the upper surface of the top support block 11 contacts the lower surface of the fork lug located above. This allows bushings or bearings to be installed on double fork lug assemblies. The auxiliary support device supports the double fork lug. During the batch production of the same product, after one adjustment, it is not necessary to repeatedly adjust the spiral fine-tuning component 1. Simply rotate the second handle 42 in the opposite direction to lower the height of the auxiliary support device, release the support, and then quickly restore the support by rotating the second handle 42 in the same direction as at the beginning.
