Description

Technical Field

[0001] This utility model relates to the field of bushing placement technology, specifically a bushing placement fixture. Background Technology

[0002] Bushing placement refers to the process of arranging ring-shaped components, such as bushings, which serve functions like support, positioning, shock absorption, or sealing, in a specific manner and order according to production processes, assembly requirements, or storage specifications. When placing bushings, their model, size, and material characteristics must be considered to avoid deformation, wear, or confusion due to improper stacking. This is commonly seen on workbenches in machining and parts assembly, on dedicated pallets, or on warehouse shelves. The placement must ensure convenient access while also complying with safety production and management standards to guarantee the bushings function properly in subsequent use.

[0003] Chinese patent CN218488931U discloses a bushing placement fixture. The key technical features include: a guide post fixing plate and a top rod fixing plate arranged front and rear; a limit post and a guide post at the front of the guide post fixing plate; a limit bolt connecting the guide post fixing plate and the top rod fixing plate; a spring fitted on the limit bolt; a bushing sleeve vertically mounted on the guide post fixing plate; and an ejector rod vertically mounted on the top rod fixing plate, extending into the bushing sleeve. An annular groove is formed on the outer front end of the bushing sleeve, containing several steel balls for fixing the bushing. A circular hole is formed in the annular groove for the steel balls to partially extend into the bushing sleeve. A binding rubber ring is fitted on the annular groove, with the steel balls contacting the inner ring of the binding rubber ring. A discharge rod is connected to the limit bolt, and a lifting handle is connected to the rear of the top rod fixing plate. This bushing placement fixture provides a convenient and accurate way to place bushings, while improving production efficiency.

[0004] Due to structural design limitations, bushing placement fixtures cannot be adjusted according to the position of the bushings on the items. When installing bushings on items of different specifications, the fixture needs to be redesigned or replaced, which increases the cost of use and leads to low production line changeover efficiency, making it difficult to meet the production needs of multiple varieties and small batches. To address this, we propose a bushing placement fixture. Utility Model Content

[0005] The purpose of this utility model is to provide a bushing placement fixture to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a bushing placement fixture, comprising a base plate, a frame fixedly connected to the surface of the base plate, a drive plate slidably connected to the surface of the frame, the size of the drive plate being adapted to the size of the base plate, a plurality of threaded holes symmetrically opened on the surfaces of the drive plate and the base plate, a plurality of round tubes mounted on the surface of the base plate, all of the round tubes being threadedly connected to the threaded holes, a drive rod inserted into the inner wall of the round tube, the drive rod being threadedly connected to the threaded hole on the surface of the drive plate, and one end of the round tube being connected to a placement platform.

[0007] The effect achieved by the above components is that by moving the position of the drive rod and the round tube according to the placement position of the bushing, bushings of different sizes can be placed, thereby improving the applicability of the fixture.

[0008] Preferably, a push rod slides through the surface of the frame, and a connecting frame is fixedly connected to one end of the push rod near the drive plate. The connecting frame is fixedly connected to the surface of the drive plate.

[0009] The effect achieved by the above components is as follows: pushing the push rod, the push rod drives the connecting frame and then drives the drive plate to slide on the frame surface, and the push rod facilitates the movement of the drive plate.

[0010] Preferably, a handle is fixedly connected to the surface of the frame, and a plurality of anti-slip strips are fixedly connected to the surface of the handle. The effect achieved by the above components is that the operator can move the frame by holding the handle, the handle facilitates gripping the frame, and the anti-slip strips increase the friction when holding the handle, thereby improving the stability when holding the handle.

[0011] Preferably, the surface of the frame is fitted with two springs, and the two ends of the springs are fixedly connected to the drive plate and the base plate, respectively.

[0012] The above components achieve the following effects: the spring restricts the position of the drive plate, preventing the drive plate from moving freely on the surface of the frame, which could cause the drive plate to collide with the base plate and cause damage; furthermore, it prevents the drive rod from penetrating the placement platform during bushing installation, thus preventing the bushing from being installed.

[0013] Preferably, a fixing plate is fixedly connected to the surface of the drive plate, and a pin slides through the surface of the fixing plate. One end of the pin is fixedly connected to an elastic rope, and the other end of the elastic rope is fixedly connected to the drive plate. A limiting hole is formed on the surface of the frame, and the size of the limiting hole is adapted to the size of the pin.

[0014] The effect achieved by the above components is that the pins limit the position of the drive plate, thereby preventing the drive plate from moving on the frame surface due to the tension of the spring when adjusting the drive rod.

[0015] Preferably, threaded rods are rotatably connected to both sides of the base plate, and clamps are threadedly connected to the surface of the threaded rods.

[0016] The effect achieved by the above components is that the clamps on both sides of the base plate hold the surface of the item, thereby fixing the position of the base plate and making it easier to place the bushing.

[0017] Preferably, both sides of the clamping plate are fixedly connected to an extension arm, and a guide rod slides through the surface of the extension arm, the guide rod being fixedly connected to the surface of the base plate.

[0018] The effect achieved by the above components is that the movement of the clamping plate will cause the extension arm to slide along the surface of the guide rod. The guide rod restricts the movement path of the extension arm, thereby restricting the movement path of the clamping plate and preventing the clamping plate from rotating during movement.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This invention involves moving a round tube and a drive rod into symmetrical threaded holes on the base plate and drive rod, respectively. The positions of the threaded holes are determined according to the bushing mounting holes on the item. After the movement is complete, several bushings are sequentially placed into the placement platform. Then, the operator can hold the handle and move the base plate above the item. At this time, pressing the drive plate will cause it to slide on the frame surface. The movement of the drive plate will push the drive rod, which will slide inside the round tube. As the drive rod moves, it will squeeze the bushing, thereby squeezing the bushing from the placement platform into the item's placement slot, thus facilitating the installation of the bushing.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-2 This utility model provides a technical solution: a bushing placement fixture, including a base plate 1, a frame 2 fixedly connected to the surface of the base plate 1, a drive plate 3 slidably connected to the surface of the frame 2, the size of the drive plate 3 being adapted to the size of the base plate 1, a plurality of threaded holes 4 symmetrically opened on the surfaces of the drive plate 3 and the base plate 1, a plurality of round tubes 6 being installed on the surface of the base plate 1, all of the round tubes 6 being threadedly connected to the threaded holes 4, a drive rod 5 being inserted into the inner wall of the round tube 6, the drive rod 5 being threadedly connected to the threaded holes 4 on the surface of the drive plate 3, and one end of the round tube 6 being connected to a placement platform 7. By moving the positions of the drive rod 5 and the round tube 6 according to the placement position of the bushing, bushings of different sizes can be placed, thereby improving the applicability of the fixture.

[0029] Reference Figure 3-5As shown in this embodiment: A push rod 8 slides through the surface of the frame 2. A connecting frame 9 is fixedly connected to one end of the push rod 8 near the drive plate 3. The connecting frame 9 is fixedly connected to the surface of the drive plate 3. Pushing the push rod 8 causes the connecting frame 9 to drive the drive plate 3 to slide on the surface of the frame 2, thus facilitating the movement of the drive plate 3. A handle 10 is fixedly connected to the surface of the frame 2. Several anti-slip strips 11 are fixedly connected to the surface of the handle 10. The operator can move the frame 2 by holding the handle 10, which facilitates gripping the frame 2. The anti-slip strips 11 increase the friction and improve the stability of the handle 10. Two springs 12 are fitted on the surface of the frame 2. The two ends of the springs 12 are fixedly connected to the drive plate 3 and the base plate 1, respectively. The springs 12 restrict the position of the drive plate 3, preventing it from moving freely on the surface of the frame 2 and causing collisions and damage between the drive plate 3 and the base plate 1. Furthermore, it prevents the drive rod 5 from penetrating the placement platform 7 during bushing installation, thus preventing the bushing from being installed. A fixing plate 13 is fixedly connected to the surface of the drive plate 3. A pin 14 slides through the surface of the fixing plate 13. One end of the pin 14 is fixedly connected to an elastic rope 16, and the other end of the elastic rope 16 is fixedly connected to the drive plate 3. A limiting hole 15 is opened on the surface of the frame 2. The size of the limiting hole 15 is adapted to the size of the pin 14. The pin 14 restricts the position of the drive plate 3, thereby preventing the drive plate 3 from moving on the surface of the frame 2 due to the tension of the spring 12 when adjusting the drive rod 5. Threaded rods 17 are rotatably connected to both sides of the base plate 1. Clamping plates 18 are threadedly connected to the surface of the threaded rods 17. The clamping plates 18 on both sides of the base plate 1 clamp the surface of the item, thereby fixing the position of the base plate 1 and further facilitating the placement of the bushing. Both sides of the clamping plate 18 are fixedly connected to extension arms 19. Guide rods 20 slide through the surface of the extension arms 19. The guide rods 20 are fixedly connected to the surface of the base plate 1. When the clamping plate 18 moves, it will cause the extension arms 19 to slide along the surface of the guide rods 20. The guide rods 20 limit the movement path of the extension arms 19, thereby limiting the movement path of the clamping plate 18 and preventing the clamping plate 18 from rotating when it moves.

[0030] Working principle: When using this bushing placement fixture, first adjust according to the placement requirements of the bushing on the item. First, pull the drive plate 3 away from the base plate 1. The drive plate 3 will slide along the surface of the frame 2 as it moves. When the drive plate 3 moves, it will pull the spring 12, which will limit the position of the drive plate 3 and prevent it from moving freely on the surface of the frame 2, thus avoiding collision and damage between the drive plate 3 and the base plate 1. This also prevents the drive rod 5 from penetrating the placement table 7 during bushing installation, which would prevent the bushing from being installed. The movement of the drive plate 3 will also drive the drive rod 5 to move. After the drive rod 5 is disengaged from the round tube 6, press the pin 14. The pin 14 will insert into the limiting hole 15, and the pin 14 will limit the position of the drive plate 3, thus preventing the drive plate 3 from moving on the surface of the frame 2 due to the tension of the spring 12 when adjusting the drive rod 5. Then, move the round tube 6 and the drive rod 5 into the symmetrical threaded holes 4 on the base plate 1 and the drive rod 5, respectively. The position of the threaded holes 4 is positioned according to the bushing mounting holes on the item. After the movement is completed, pull the pin 14 out of the limiting hole 15. The pin 14 is fixed to the surface of the fixing plate 13 by the tension of the elastic rope 16, thus preventing the pin 14 from falling off the fixing plate 13. When the fixed plate 13 detaches and is lost, the spring 12 will cause the drive plate 3 to reset. The drive plate 3 will then cause the drive rod 5 to insert into the round tube 6. The end face of the drive rod 5 will be flush with the inner wall of the placement platform 7. At this time, several bushings are placed into the placement platform 7 in sequence. Then, the operator can hold the handle 10 to move the base plate 1 above the item and then rotate the threaded rod 17. The rotation of the threaded rod 17 will cause the clamping plate 18 to move through the thread. The movement of the clamping plate 18 will cause the extension arm 19 to slide along the surface of the guide rod 20. The guide rod 20 will limit the movement path of the extension arm 19, thereby limiting the movement of the clamping plate 18. The path is designed to prevent the clamping plate 18 from rotating during movement. The clamping plate 18 moves closer to the object until the clamping plates 18 on both sides of the base plate 1 clamp the surface of the object, thus fixing the position of the base plate 1. Then, the operator can hold the handle 10 and push the push rod 8, which drives the connecting frame 9 and then drives the drive plate 3 to slide on the surface of the frame 2. The movement of the drive plate 3 will push the drive rod 5, and the drive rod 5 will slide inside the round tube 6. When the drive rod 5 moves, it will squeeze the bushing, thereby squeezing the bushing from the placement table 7 into the placement slot of the object, thus facilitating the installation of the bushing.
