Description

Technical Field

[0001] This utility model relates to the field of mechanical parts technology, specifically an adjustable bushing separation device. Background Technology

[0002] Bushings are fittings used on the exterior of mechanical components to achieve functions such as sealing and wear protection. They are typically installed in parts requiring isolation, support, or protection, such as valves, bearings, and gears. Bushings play an important role in many fields, including automotive manufacturing, machining, food processing, and electrical equipment.

[0003] As the usage time increases, the bushing will gradually wear out and need to be replaced. Since the bushing models are different, the current bushing separation device is often used in sets of various models, which requires carrying a large number of parts at once, resulting in a large weight and inconvenience for carrying. Therefore, an adjustable bushing separation device is proposed. Utility Model Content

[0004] The purpose of this invention is to provide an adjustable bushing separation device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an adjustable bushing separation device, including a pull plate, a contact assembly installed inside the pull plate, the contact assembly including multiple limiting grooves opened on the outer circumference of the pull plate, the multiple limiting grooves being equally distributed, a contact plate being slidably connected inside each of the multiple limiting grooves, a support rod being rotatably connected to the middle of the top outer wall of each of the multiple contact plates, a common connecting frame being rotatably connected to one end of the top of each of the multiple support rods, a second lead screw being rotatably connected to the middle of the bottom inner wall of the pull plate, and the connecting frame being threadedly connected to the outside of the second lead screw.

[0006] This allows the device to be adjusted according to the bushing diameter, ensuring that bushings of different diameters can be disassembled without the need to carry a large number of accessories. It is convenient to use. The position of the contact plate can be adjusted as needed to ensure that multiple contact plates can make contact with the end of the bushing. The screw rod is driven to rotate on the bottom wall of the pull plate by the knob. Because the contact plate is restricted by the limiting groove and cannot move left or right, and the support rod is restricted by the contact plate and is at the same level, the connecting frame can only move vertically under the restriction of multiple support rods. The screw rod can then drive the connecting frame to move downward. The connecting frame, through the support rod, will drive multiple contact plates to move outward synchronously until the contact plates move to the appropriate position.

[0007] As a further preferred embodiment of this technical solution, a separation component is installed on the outside of the pull plate. The separation component includes a lead screw rotatably connected to the top outer wall of the pull plate. A connecting plate is threaded onto the outside of the lead screw, and an abutment sleeve is slidably inserted into the inside of the connecting plate.

[0008] As a further preferred embodiment of this technical solution, a positioning frame is coaxially fixed to the outer wall of the bottom of the connecting plate. The positioning frame surrounds the outside of the lead screw and is arranged in a frustum shape.

[0009] As a further preferred embodiment of this technical solution, the outer circumferential wall of the abutment sleeve is fixedly connected with a plurality of equally spaced extension plates.

[0010] As a further preferred embodiment of this technical solution, a locking post is fixedly connected to the bottom outer wall of one of the extension plates.

[0011] The extension plate on the outside of the abutment sleeve can increase the contact area of ​​the abutment sleeve, preventing the abutment sleeve from directly entering the bushing due to its large diameter. The locking post at the bottom of the extension plate can contact the external equipment, thus ensuring that the abutment sleeve will not be rotated by the lead screw. There is no need to manually press the connecting plate. The lead screw rotates and moves upward along the connecting plate, and the pull plate will drive the bushing to move synchronously. In this way, the bushing can be easily removed.

[0012] As a further preferred embodiment of this technical solution, a turntable is coaxially fixed to one end of the lead screw, and the diameter of the turntable is larger than the diameter of the lead screw.

[0013] As a further preferred embodiment of this technical solution, a hexagonal groove is provided on the top outer wall of the lead screw, and the hexagonal groove is located in the middle of the turntable.

[0014] This utility model provides an adjustable bushing separation device, which has the following advantages:

[0015] (1) By setting up contact components, the device can be adjusted according to the diameter of the bushing, ensuring that bushings of different diameters can be disassembled without carrying a large number of supporting devices. It is convenient to use. The position of the contact plate can be adjusted as needed to ensure that multiple contact plates can contact the end of the bushing. The screw rod is driven to rotate on the bottom wall of the pull plate by the knob. Because the contact plate is restricted by the limiting groove and cannot move left or right, and the support rod is restricted by the contact plate and is at the same level, the connecting frame can only move vertically under the restriction of multiple support rods. The screw rod can drive the connecting frame to move downward. The connecting frame will drive multiple contact plates to move outward synchronously through the support rod until the contact plate moves to the appropriate position.

[0016] (2) By setting up a separation component, an extension plate and a locking post, the extension plate outside the abutment sleeve can increase the contact area of ​​the abutment sleeve, thus preventing the abutment sleeve from directly entering the bushing due to its large diameter. The locking post at the bottom of the extension plate can contact the external equipment, thereby ensuring that the abutment sleeve will not be rotated by the lead screw. There is no need to manually press the connecting plate. The lead screw rotates and moves up along the connecting plate, and the pull plate will drive the bushing to move synchronously. In this way, the bushing can be easily removed. Attached Figure Description

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model provides a technical solution: such as Figure 3 As shown in Figure 4, in this embodiment, an adjustable bushing separation device includes a pull plate 1. A contact component 8 is installed inside the pull plate 1. The contact component 8 includes multiple limiting grooves 801 opened on the outer circumference of the pull plate 1. The multiple limiting grooves 801 are distributed at equal intervals. A contact plate 802 is slidably connected inside each of the multiple limiting grooves 801. A support rod 805 is rotatably connected to the middle of the top outer wall of each of the multiple contact plates 802. The top end of each of the multiple support rods 805 is rotatably connected to the same connecting frame 804. A second lead screw 803 is rotatably connected to the middle of the bottom inner wall of the pull plate 1. The connecting frame 804 is threaded to the outside of the second lead screw 803.

[0024] Adjust the position of the contact plate 802 as needed to ensure that multiple contact plates 802 can make contact with the end of the bushing. Drive the screw 803 to rotate on the bottom wall of the pull plate 1 by the knob. Since the contact plate 802 is restricted by the limiting groove 801 and cannot move left or right, and the support rod 805 is restricted by the contact plate 802 and is at the same level, the connecting frame 804 can only move vertically under the restriction of multiple support rods 805. The screw 803 can drive the connecting frame 804 to move downward. The connecting frame 804 will drive multiple contact plates 802 to move outward synchronously through the support rods 805 until the contact plates 802 move to the appropriate position.

[0025] like Figure 2 and Figure 3 As shown, a separation component 7 is installed on the outside of the pull plate 1. The separation component 7 includes a lead screw 701 rotatably connected to the top outer wall of the pull plate 1. A connecting plate 703 is threaded on the outside of the lead screw 701. An abutment sleeve 702 is slidably inserted into the inside of the connecting plate 703.

[0026] A positioning frame 2 is coaxially fixed to the bottom outer wall of the connecting plate 703. The positioning frame 2 surrounds the lead screw 701 and is shaped like a frustum. When the connecting plate 703 is pressed down, the connecting plate 703 drives the positioning frame 2 to slide down along the abutment sleeve 702. Then the positioning frame 2 contacts the inner wall of the bushing. Since the positioning frame 2 is shaped like a frustum, its cooperation ensures that the center line of the abutment sleeve 702 and the center line of the bushing are aligned, thereby ensuring that the contact component 8 can contact the bushing precisely, so that the separation operation can proceed smoothly.

[0027] The outer circumference of the abutment sleeve 702 is fixedly connected with multiple equally spaced extension plates 3.

[0028] One of the extension plates 3 has a locking post 4 fixedly connected to the bottom outer wall.

[0029] The extension plate 3 on the outside of the abutment sleeve 702 can increase the contact area of ​​the abutment sleeve 702, preventing the abutment sleeve 702 from directly entering the bushing due to its large diameter. The locking post 4 at the bottom of the extension plate 3 can contact the external equipment, thereby ensuring that the abutment sleeve 702 will not be rotated by the lead screw 701. Without manually pressing the connecting plate 703, the lead screw 701 rotates and moves upward along the connecting plate 703, and the pull plate 1 will drive the bushing to move synchronously. In this way, the bushing can be easily removed.

[0030] like Figure 1 As shown in Figure 2, a turntable 5 is coaxially fixed to one end of the lead screw 701, and the diameter of the turntable 5 is larger than the diameter of the lead screw 701, which can increase the power transmission arm and make separation easier.

[0031] like Figure 1As shown, a hexagonal groove 6 is provided on the top outer wall of the lead screw 701, and the hexagonal groove 6 is located in the middle of the turntable 5. The external drilling machine can drive the lead screw 701 by inserting it into the hexagonal groove 6, thus providing a wider range of driving methods.

[0032] This utility model provides an adjustable bushing separation device, the specific working principle of which is as follows:

[0033] When the device is in operation, pull plate 1 is passed through the bushing and moved to the other side, then...

[0034] Adjust the position of the contact plates 802 as needed to ensure that multiple contact plates 802 are in contact with the bushing ends. Drive the lead screw 803 to rotate on the bottom wall of the pull plate 1 via a knob. Because the contact plates 802 are restricted from moving left or right by the limiting groove 801, and the support rods 805 are also restricted by the contact plates 802 and are at the same level, the connecting frame 804 can only move vertically under the restriction of multiple support rods 805. The lead screw 803 then drives the connecting frame 804 to move downwards. The connecting frame 804, through the support rods 805, drives multiple contact plates 802 to move outwards synchronously until the contact plates 802 reach the appropriate position.

[0035] Then, the connecting plate 703 is pressed down, causing the positioning frame 2 to slide downwards along the abutment sleeve 702. The positioning frame 2 then contacts the inner wall of the bushing. Since the positioning frame 2 is frustum-shaped, its cooperation ensures that the centerline of the abutment sleeve 702 and the centerline of the bushing are aligned, thus guaranteeing that the contact component 8 can precisely contact the bushing, facilitating smooth separation.

[0036] The extension plate 3 on the outside of the abutment sleeve 702 can increase the contact area of ​​the abutment sleeve 702, preventing the abutment sleeve 702 from directly entering the bushing due to its large diameter. The locking post 4 at the bottom of the extension plate 3 can contact external equipment, thereby ensuring that the abutment sleeve 702 will not be rotated by the lead screw 701, without the need to manually press the connecting plate 703.

[0037] Then, the turntable 5 drives the lead screw 701 to rotate, or it can be driven by an electric drill through the hexagonal slot 6. The lead screw 701 rotates and moves upward along the connecting plate 703, and the pull plate 1 drives the bushing to move synchronously. In this way, the bushing can be easily removed.

[0038] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
