Description

Technical Field

[0001] This utility model relates to the technical field of horizontal machining center parts, and more specifically to an exchange turntable with an automatic oil dispensing fixture interface. Background Technology

[0002] An exchange turntable with an automatic oil dispensing fixture interface is a device used in industrial automation, typically for the rapid exchange and positioning of workpieces on a production line.

[0003] Based on publication number CN216882697U, published on 2022-07-05, an exchange turntable with an automatic oil dispensing clamp interface is disclosed. It adopts an oil dispensing shaft and an annular oil groove structure, so that the overall structure has several interconnected oil circuits. It performs tightening and loosening actions on the positioning cone seat, thereby realizing the clamping or loosening of the turntable table surface. At the same time, corresponding hydraulic quick-change plugs are installed above the rotating base of the turntable and below the table surface.

[0004] However, in the prior art, including the aforementioned patent, the hydraulic quick-connect plug can only ensure that the oil circuits in the turntable base and the platform are interconnected. At this time, the base and the platform may not be fully connected, and the oil leakage problem will occur when oil is introduced into the oil circuit. Utility Model Content

[0005] The purpose of this invention is to provide an exchange turntable with an automatic oil dispensing fixture interface to solve the above-mentioned problems.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an exchange turntable with an automatic oil dispensing fixture interface, comprising a base and a turntable;

[0007] A boring hole formed on the base and connected to the oil passage;

[0008] An interface seat that is fixedly installed inside the boring hole;

[0009] A plug that is slidably installed inside the interface seat and used to block the oil passage;

[0010] A transmission rod is radially slidably mounted on the interface seat and moves synchronously with the plug block;

[0011] The transmission rod is pushed out of the interface seat as the base and turntable approach each other to ensure the oil passage is unobstructed.

[0012] Preferably, the interface seat is slidably provided with a slide block that forms a sliding engagement with the transmission rod, and the block is fixedly provided on the slide block. The slide block is provided with a second spring for maintaining a predetermined distance from the interface seat.

[0013] Preferably, the port of the interface seat is fixedly provided with a sealing ring, and multiple clips are slidably provided on the sealing ring along the radial direction.

[0014] Preferably, the turntable is provided with an insertion port that cooperates with the card to remove or retract.

[0015] Preferably, the interface base is slidably provided with a slider that moves synchronously with the card, and the slider is fixedly provided with a pin that engages with the card.

[0016] Preferably, the card is provided with a roller that is rotatably mounted, and the roller is eccentrically mounted.

[0017] In the above technical solution, the exchange turntable with automatic oil dispensing fixture interface provided by this utility model has the following beneficial effects: when the base and the turntable are not connected, the block is located in the bucket-shaped part and blocks the oil inlet cavity to avoid leakage. When the base and the turntable are close to and connected, the distance between the block and the bucket-shaped part increases, and the oil passage is unobstructed. This allows the oil passage to flow normally only after the connection is completed, thus avoiding the problem of leakage. Attached Figure Description

[0026] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0027] like Figure 1-5 As shown, an exchange turntable with an automatic oil dispensing fixture interface includes a base 1 and a turntable 2.

[0028] A boring hole formed on base 1 and connected to the oil passage;

[0029] Interface seat 3 is fixedly installed inside the boring hole;

[0030] A plug 52 is slidably disposed within the interface seat 3 and is used to block the oil passage;

[0031] A transmission rod 4 is radially slidably mounted on the interface seat 3 and moves synchronously with the block 52;

[0032] The transmission rod 4 is pushed out of the interface seat 3 as the base 1 and turntable 2 approach each other to make the oil passage unobstructed.

[0033] Specifically, it also includes a conical opening 92 fixedly installed on the turntable 2, an oil inlet chamber opened in the interface seat 3, and the bottom of the oil inlet chamber is a bucket-shaped part corresponding to the plug 52. When the base 1 and the turntable 2 are not connected, the plug 52 is close to the bucket-shaped part and seals the oil inlet chamber to prevent leakage. When the base 1 and the turntable 2 are close and connected, the transmission rod 4 is squeezed out of the interface seat 3 by the conical opening 92, and drives the plug 52 away from the bucket-shaped part, no longer sealing the oil inlet chamber. At this time, the oil passage is unobstructed.

[0034] In the above technology, when the base 1 and the turntable 2 are not connected, the block 52 is located in the bucket-shaped part and blocks the oil inlet cavity to prevent leakage. After the base 1 and the turntable 2 are close to and connected, the distance between the block 52 and the bucket-shaped part increases. At this time, the oil passage is unobstructed, so that the oil passage can only be normally connected after the connection is completed, thus avoiding the problem of leakage.

[0035] As a further embodiment of this utility model, a slide block 5 is slidably disposed on the interface seat 3 to form a sliding engagement with the transmission rod 4, and a block 52 is fixedly disposed on the slide block 5. A second spring 51 is disposed on the slide block 5 to maintain a predetermined distance from the interface seat 3.

[0036] Specifically, a first spring 41 is provided on the transmission rod 4 to drive the transmission rod 4 close to the interface seat 3. The slide 5 is provided with an inclined surface that slides and engages with the transmission rod 4. In the unconnected state, the slide 5 is limited by the transmission rod 4 and remains in its original position. At this time, the block 52 is located in the bucket-shaped part and blocks the oil inlet cavity. The second spring 51 is in a contracted and stored state. At this time, the oil passage is blocked. Only after the base 1 and the turntable 2 approach and connect, the conical opening 92 pushes the transmission rod 4, causing the transmission rod 4 to slide radially and be squeezed out of the interface seat 3, thus no longer limiting the slide 5. The elastic potential energy of the second spring 51 is released, pushing the slide 5 and causing a gap to be created between the block 52 and the bucket-shaped part. The oil passage is unobstructed, avoiding oil supply when the base 1 and the turntable 2 are not fully connected, which would cause leakage.

[0037] As another embodiment provided by this utility model, the port of the interface base 3 is fixedly provided with a sealing ring 6, and multiple clips 7 are slidably provided on the sealing ring 6 along the radial direction.

[0038] Specifically, the sealing ring 6 is interference-fitted with the inner wall of the conical opening 92. After the base 1 and the turntable 2 are docked, the sealing ring 6 fits tightly against the inner wall of the conical opening 92 to further prevent leakage. The locking piece 7 on the sealing ring 6 is provided with an elastic element 72 that brings multiple locking pieces 7 close to each other. Under the elastic action of the elastic element 72, the locking piece 7 is located at the center of the sealing ring 6. During the docking process, since the turntable 2 is provided with a socket 9 that engages with the locking piece 7, multiple locking pieces 7 are pushed by the socket 9 and move radially away from the center. At this time, the locking piece 7 is pressed tightly against the socket 9 by the elastic force of the elastic element 72, which increases the friction and prevents it from falling off.

[0039] As a further embodiment of this utility model, the interface base 3 is slidably provided with a slide member 8 that moves synchronously with the card member 7, and the slide member 8 is fixedly provided with a pin 81 that engages with the card member 7.

[0040] Specifically, in the unconnected state, the locking piece 7 is located at the center of the sealing ring 6. The sliding piece 8 has a groove that slides and connects to the fixing rod on the locking piece 7. At this time, the sliding piece 8 is in the initial position, and the pin 81 engages with the locking piece 7. When the locking piece 7 is pushed away from the center radially by the insertion port 9, the fixing rod drives the sliding piece 8 to move upward, thereby causing the pin 81 to move upward and be offset from the locking piece 7. At this time, the pin 81 no longer engages with the locking piece 7, ensuring that the locking piece 7 can only move after the sealing ring 6 seals the conical opening 92, further preventing oil leakage.

[0041] As another embodiment provided by this utility model, a roller 71 is rotatably provided on the card 7, and the roller 71 is eccentrically arranged.

[0042] Specifically, the roller 71 is divided into a long axis and a short axis by the pivot, and a torsion spring is provided on the roller 71. In the initial state, the long axis of the roller 71 is naturally located at the bottom due to gravity, and the short axis is located at the top. In the unconnected state, the locking piece 7 is located at the center of the sealing ring 6. During the connection process, multiple locking pieces 7 are pushed by the insertion port 9 and move radially away from the center, and rub against the outer wall of the roller 71, thereby driving the roller 71 to rotate. This makes the locking piece 7 smoother when pushed, and causes the contact side of the roller 71 with the insertion port 9 to rotate from the short axis to the long axis. The torsion spring deforms and stores force until the roller 71 corresponds to the recess 91 opened on the insertion port 9. The elastic force of the torsion spring locks the recess 91 and the roller 71, which plays a role in preventing it from falling off.

[0043] Working principle: In the unconnected state, the slide 5 is limited by the transmission rod 4 and remains in its original position. At this time, the block 52 is located in the bucket-shaped part and blocks the oil inlet. The second spring 51 is in a contracted and stored state. At this time, the oil passage is blocked, the slide 8 is in the initial position, and the pin 81 engages with the locking piece 7. After the base 1 and the turntable 2 approach and connect, multiple locking pieces 7 are pushed by the insertion port 9 and move radially away from the center. The sealing ring 6 tightly fits the inner wall of the conical opening 92, causing the pin 81 to move upward and be misaligned with the locking piece 7. At this time, the pin 81... No longer engaging with the clip 7, the contact side of the roller 71 with the socket 9 rotates from the short axis to the long axis, the torsion spring deforms and stores force until the roller 71 corresponds to the recess 91 on the socket 9, and the elastic force of the torsion spring locks the recess 91 and the roller 71. Then the conical opening 92 pushes the transmission rod 4, causing the transmission rod 4 to slide radially and be squeezed out of the interface seat 3, thus no longer limiting the slide 5. The elastic potential energy of the second spring 51 is released, pushing the slide 5 and causing the block 52 to create a gap between the block 52 and the bucket-shaped part, so that the oil passage is unblocked.

[0044] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
