Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, specifically to a tool holder slide assembly for a welding and turning machine. Background Technology

[0002] A cladding and turning machine is a piece of equipment that integrates cladding and turning processes, and it has wide applications in mechanical manufacturing, repair, and other fields. The tool holder slide assembly is an important component of the cladding and turning machine, and its function is to drive the tool holder to achieve precise movement to meet machining requirements.

[0003] In existing integrated welding and lathe assembly, the tool holder slide assembly mainly includes a slide rail located at the top of the machine body, a sliding block slidably connected to the slide rail, and a slide body fixedly connected to the sliding block and movable at the top of the machine body. After prolonged use, the sliding block is prone to severe wear, requiring replacement by operators. Replacing the sliding block typically requires disassembling it from the slide body. Furthermore, due to the excessive weight of the slide body, a lifting device is needed to lift it before the sliding block can be replaced. This structure makes the sliding block replacement process cumbersome and inefficient, requiring improvement. Utility Model Content

[0004] To simplify the process of replacing the sliding block and improve the efficiency of replacement, this utility model provides a tool holder slide assembly for a welding machine.

[0005] The present invention provides a tool holder slide assembly for a welding and machining integrated machine, which adopts the following technical solution: A tool holder slide assembly for a lathe welding machine includes a lathe welding machine body, a sliding block slidably mounted on the lathe welding machine body, and a slide body mounted on top of the sliding block. It also includes a support mechanism and a pushing mechanism. The support mechanism is disposed between the lathe welding machine body and the slide body to support the slide body. The pushing mechanism is connected to the support mechanism and is used to simultaneously push the sliding block out from between the lathe welding machine body and the slide body for easy replacement.

[0006] By adopting the above technical solution, when replacing the sliding block, the support mechanism first applies upward force to the slide body to relieve the pressure on the sliding block, and then the pushing mechanism pushes the sliding block out from the bottom of the slide body. The pushing mechanism can work simultaneously during the operation of the support mechanism, allowing the sliding block to be replaced concurrently as the slide body is lifted. This facilitates the replacement of the sliding block. Compared to existing methods that require lifting the slide body with a hoisting device to replace the sliding block, this structure simplifies the sliding block replacement process for operators and increases efficiency.

[0007] Optionally, the support mechanism includes a bidirectional threaded rod, a drive block threaded to the outside of the bidirectional threaded rod, a connecting plate, and a drive rod; the connecting plate is lifted and installed between the welding machine body and the slide plate body; the connecting plate and the drive block are hinged together by the drive rod, so that the lifting and lowering of the connecting plate is achieved by the displacement of the drive block on the bidirectional threaded rod.

[0008] By adopting the above technical solution, the drive block can move horizontally along the bidirectional threaded rod by rotating the bidirectional threaded rod; and since the connecting plate is restricted to only lifting and lowering, the connecting plate can be driven to lift and lower by the drive rod when the drive block moves.

[0009] Optionally, a buffer assembly for absorbing the impact force generated during the lifting process is provided between the connecting plate and the main body of the fusion machine. The buffer assembly includes a support plate that abuts against the main body of the fusion machine and a buffer spring that connects the connecting plate and the support plate.

[0010] By adopting the above technical solution, and by connecting a buffer spring between the connecting plate and the support plate, when the support plate is supported on the body of the welding machine, it can effectively avoid directly lifting the slide body, and the force applied by the support mechanism to the slide body can gradually increase; at the same time, the buffer spring absorbs the impact force generated when the connecting plate supports the slide body for lifting and lowering, thereby preventing damage to the connecting plate during lifting.

[0011] Optionally, a telescopic guide post is provided between the connecting plate and the skateboard body. The telescopic guide post includes two telescopic units that extend and retract with each other to guide and limit the lifting and lowering of the connecting plate.

[0012] By adopting the above technical solution, the lifting and lowering of the connecting plate is limited and guided by the telescopic guide column, so that the connecting plate remains stable during the lifting and lowering process. This makes it difficult for the skateboard body to move horizontally with the drive block when the connecting plate is lifted and lowered to support it.

[0013] Optionally, the slide body is provided with a T-shaped groove, and a T-shaped slider that slides and cooperates with the T-shaped groove is fixedly installed on the top of the drive block.

[0014] By adopting the above technical solution, the drive block is circumferentially limited by the cooperation of the T-shaped slider and the T-shaped groove, so that when the bidirectional threaded rod rotates, the drive block is not easy to rotate circumferentially with the bidirectional threaded rod, thereby generating horizontal displacement.

[0015] Optionally, the support mechanisms are symmetrically arranged at the bottom of the skateboard body and the two support mechanisms are connected by a transmission mechanism; the transmission mechanism includes a geared motor, a rotating shaft connected to the output end of the geared motor, and a worm gear assembly connecting the rotating shaft and the bidirectional threaded rod.

[0016] By adopting the above technical solution, the rotary shaft is driven to rotate by the geared motor, the rotary shaft drives the worm gear assembly, and then the worm gear assembly drives the two bidirectional threaded rods to rotate synchronously, thereby facilitating the synchronous lifting and lowering of the two support mechanisms to raise the skateboard body.

[0017] Optionally, the pushing mechanism includes a pushing rod, a pushing block, and a pushing spring; the pushing rod is connected to the driving block, the pushing block is connected to the end of the pushing rod away from the driving block through the pushing spring, and the pushing block abuts against the sliding block.

[0018] By adopting the above technical solution, when the drive block moves and supports the skateboard body through the connecting plate, the drive block will simultaneously drive the push block to move through the push rod connected to it, thereby driving the sliding block that is in contact with the push block to move. This allows the sliding block to be pushed out and replaced simultaneously when supporting the skateboard body. At the same time, by setting the push spring 52, it is avoided that the sliding block is moved directly through the push rod, and it is also avoided that the sliding block moves immediately after the drive block moves, because the drive block cannot provide effective support for the skateboard body immediately after moving, and the sliding block still bears a lot of the weight of the skateboard body, thus avoiding damage to the drive rod.

[0019] Optionally, the push rod is fixedly connected to the drive block.

[0020] By adopting the above technical solution, a first structure of the pushing mechanism is disclosed. In this pushing mechanism, the pushing rod is fixedly connected to the driving block. When the bidirectional threaded rod drives the driving block to move horizontally, the two driving blocks move away from each other and are in the same direction as the sliding block is pushed out. Therefore, the pushing rod is directly driven to move horizontally through the driving block, thereby pushing out the sliding block, which facilitates the replacement of the sliding block. The above structure is simple and can apply force well.

[0021] Optionally, the push rod is rotatably mounted on the skateboard body and is rotatably connected to the drive block.

[0022] By adopting the above technical solution, a second structure of the pushing mechanism is specifically disclosed. In this pushing mechanism, the pushing rod is rotatably connected to the driving block and the slide body. When the bidirectional threaded rod drives the driving block to move horizontally and approach each other, its direction is opposite to that of the sliding block being pushed out. The driving block drives the pushing rod to rotate, so that the end of the pushing rod away from the driving block can drive the sliding block to move in the opposite direction, thereby facilitating the replacement of the sliding block. Furthermore, when the pushing rod is rotatably connected to the slide body, a lever structure can be formed, making it easier to push out the sliding block.

[0023] Optionally, a limiting mechanism is provided between the skateboard body and the sliding block; the limiting mechanism includes a limiting rod movably inserted into the sliding block, a locking component connected to the limiting rod, and a first return spring sleeved on the limiting rod; the locking component drives the limiting rod to retract from the sliding block and locks the limiting rod; the first return spring drives the limiting rod to always have a tendency to return to the sliding block.

[0024] By adopting the above technical solution, the limiting rod is pulled upward to detach from the skateboard body and the sliding block, so that the sliding block is no longer fixed to the skateboard body. When the connecting plate lifts the skateboard body, it will simultaneously push the sliding block out of the bottom of the skateboard body through the pushing block, making it convenient to replace the sliding block. At the same time, the upward-moving limiting rod can be fixed by the locking component to prevent the limiting rod from re-inserting into the sliding block during the sliding block's retraction process, which would cause the skateboard body and the sliding block to be fixed again.

[0025] In summary, this utility model has at least one of the following beneficial technical effects: 1. When replacing the sliding block, the support mechanism first applies upward force to the slide body to relieve the pressure on the sliding block, and then the pushing mechanism pushes the sliding block out from the bottom of the slide body. The pushing mechanism can work simultaneously during the operation of the support mechanism, allowing the sliding block to be replaced concurrently as the slide body is lifted. This facilitates the replacement of the sliding block, and compared to existing methods that require lifting the slide body with a hoisting device to replace the sliding block, the above structure makes the sliding block replacement process simpler and more efficient for operators. 2. When the drive block moves and supports the skateboard body through the connecting plate, the drive block will simultaneously move through the push rod connected to it, thereby moving the sliding block that is in contact with the push block. This allows the sliding block to be pushed out and replaced simultaneously while supporting the skateboard body. At the same time, the push spring 52 is set to prevent the sliding block from moving directly through the push rod, and to prevent the sliding block from moving immediately after the drive block moves. This is because the drive block cannot provide effective support for the skateboard body immediately after moving, and the sliding block still bears a lot of the weight of the skateboard body, thus preventing damage to the drive rod. 3. By pulling the limit rod upward, the limit rod is disengaged from the skateboard body and the sliding block, so that the sliding block is no longer fixed to the skateboard body. When the connecting plate lifts the skateboard body, it will simultaneously push the sliding block out of the bottom of the skateboard body through the push block, making it easy to replace the sliding block. At the same time, the upward-moving limit rod can be fixed by the locking component to prevent the limit rod from re-inserting into the sliding block during the sliding block's retraction process, which would cause the skateboard body and the sliding block to be fixed again.

[0028] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0029] This utility model discloses a tool holder and slide plate assembly for a welding and machining integrated machine.

[0030] Reference Figure 1 and Figure 2 A tool holder slide assembly for a fusion lathe includes a fusion lathe body 1, sliding blocks 11, a slide body 12, a support mechanism 2, and a pushing mechanism 5. The fusion lathe body 1 has a guide rail, and four sliding blocks 11 are slidably mounted on the guide rail. The slide body 12 is fixed to the sliding blocks 11, with the sliding blocks 11 located at the four corners of the bottom of the slide body 12. The support mechanism 2 is disposed between the fusion lathe body 1 and the slide body 12, and is used to support the slide body 12 when the sliding blocks 11 are replaced. In this embodiment, the support mechanism 2 is fixedly installed on the bottom plate of the slide body 12 so that it can move synchronously with the slide body 12 when not in use. The pushing mechanism 5 is connected to the support mechanism 2, and is driven by the support mechanism 2 to operate, synchronously pushing the sliding blocks 11 out from between the fusion lathe body 1 and the slide body 12 during the process of the support mechanism 2 supporting the slide body 12.

[0031] When replacing the sliding block 11, first disconnect the connection between the skateboard body 12 and the sliding block 11, then support the skateboard body 12 through the support mechanism 2, and simultaneously push out the sliding block 11 through the push-out mechanism.

[0032] There are two support mechanisms 2, which are symmetrically distributed under the skateboard body 12 and can support the skateboard body 12 on both sides at the same time.

[0033] Reference Figure 2 and Figure 3The support mechanism 2 includes a bidirectional threaded rod 21, a drive block 22, a connecting plate 24, and a drive rod 23. The bidirectional threaded rod 21 is rotatably mounted on the bottom of the slide body 12, and has two external threads with opposite directions of rotation on its outer side. There are two drive blocks 22, each threadedly connected to the bidirectional threaded rod 21 and located on different external threads. The number of drive rods 23 corresponds one-to-one with the number of drive blocks 22; one end of each drive rod 23 is rotatably connected to the bottom of the drive block 22, and the other end is rotatably connected to the top of the connecting plate 24.

[0034] When the bidirectional threaded rod 21 rotates, the drive block 22 moves along the bidirectional threaded rod 21 and drives the drive rod 23 to rotate. At this time, the end of the drive rod 23 away from the drive block 22 can rise and fall, thereby driving the connecting plate 24 to rise and fall. When the connecting plate 24 is in the lowered state, the support mechanism 2 can support the slide body 12.

[0035] Furthermore, a telescopic guide post 25 is provided between the connecting plate 24 and the skateboard body 12. The lower end of the telescopic guide post 25 is fixed to the connecting plate 24, and the upper end is fixed to the skateboard body 12. There are four telescopic guide posts 25, located at the four corners of the connecting plate 24. The telescopic guide post 25 has a telescopic tube structure, including two telescopic units that extend and retract from each other. When the drive block 22 drives the connecting plate 24 to rise and fall, the telescopic guide post 25 can extend and retract, thereby guiding the connecting plate 24 to rise and fall.

[0036] Reference Figure 2 and Figure 3 Furthermore, a T-shaped groove 27 is provided on the slide body 12, and a T-shaped slider 26 that slides and engages with the T-shaped groove 27 is fixedly installed on the top of the drive block 22. The T-shaped slider 26 can limit the movement of the drive block 22 by engaging with the T-shaped groove 27, thus restricting the circumferential rotation of the drive block 22. When the bidirectional threaded rod 21 rotates, the drive block 22 can only move horizontally, and the T-shaped slider 26 can move synchronously within the T-shaped groove 27.

[0037] Furthermore, a buffer assembly 3 is provided between the connecting plate 24 and the welding machine body 1. The buffer assembly 3 includes a support plate 31 and a buffer spring 32. The support plate 31 is located below the connecting plate 24 and can abut against the welding machine body 1. The buffer spring 32 is located between the connecting plate 24 and the support plate 31. When the connecting plate 24 descends and the support plate 31 abuts against the welding machine body 1, the buffer spring 32 can be compressed. Moreover, when the bidirectional threaded rod 21 rotates, the pressure of the buffer spring 32 on the support plate 31 gradually increases, and the support plate 31 gradually applies force to support the slide plate body 12.

[0038] Reference Figure 4 and Figure 5To enable the two support mechanisms 2 to be driven synchronously, the two support mechanisms 2 are connected by a transmission mechanism 4. The transmission mechanism 4 includes a geared motor 41, a rotating shaft 42, and a worm gear assembly 43. The worm gear assembly 43 also includes a worm section 431 and two worm wheels 432 that mesh with the worm section 431.

[0039] The geared motor 41 is fixedly mounted on the slide body 12. The output end of the geared motor 41 is fixedly connected to the rotating shaft 42 via a coupling. The worm section 431 is fixedly mounted on the rotating shaft 42, and the worm wheel 432 is fixedly mounted on the outside of the bidirectional threaded rod 21. Each bidirectional threaded rod 21 is connected to the rotating shaft 42 via a corresponding worm wheel and worm assembly 43.

[0040] When working, the geared motor 41 is started first. At this time, the geared motor 41 will drive the rotating shaft 42 to rotate, and drive the bidirectional threaded rod 21 to rotate through the worm gear assembly 43.

[0041] Refer to Figure 6 and Figure 7 The pushing mechanism 5 includes a pushing rod 51, a pushing block 53, and a pushing spring 52.

[0042] The push rod 51 is rotatably mounted on the bottom of the skateboard body 12 via a hinge shaft, and one end of the push rod 51 is rotatably connected to the drive block 22, while the other end is connected to the push block 53 via the push spring 52. The end of the push block 53 away from the push spring 52 abuts against the sliding block 11.

[0043] In this embodiment, the ends of the two drive rods 23 furthest from the drive block 22 move closer together. Only when the two drive blocks 22 move closer together can the support plate 31 descend to provide support. Therefore, the direction of movement of the drive block 22 is opposite to the direction of retraction of the sliding block 11. In this case, since the push rod 51 is rotatably mounted on the skateboard body 12, when the two drive blocks 22 move closer together, the ends of the two push rods 51 furthest from the drive block 22 move away from each other, thus allowing the sliding block 11 to be pushed out from the bottom of the skateboard body 12.

[0044] In other embodiments, one end of the push rod 51 is fixedly connected to the drive block 22, and the other end is connected to the push block 53 via a push spring 52. The ends of the two drive rods 23 furthest from the drive block 22 are separated from each other. Only when the two drive blocks 22 are separated from each other can the support plate 31 descend to provide support. Therefore, the direction of movement of the drive block 22 is the same as the direction of retraction of the sliding block 11. In the above case, since the push rod 51 is fixedly connected to the drive block 22, when the two drive blocks 22 are separated from each other, the ends of the two push rods 51 furthest from the drive block 22 also move away from each other, thus enabling the sliding block 11 to be pushed out from the bottom plate of the slide body 12.

[0045] Reference Figure 4 , Figure 8 and Figure 9 Furthermore, since the sliding block 11 is locked to the skateboard body 12 before it is disassembled, the sliding block 11 needs to be unlocked in order to push the sliding block 11 out from under the skateboard body 12. Therefore, a limit mechanism 6 is provided between the sliding block 11 and the skateboard body 12 to lock and unlock the sliding block 11.

[0046] The limiting mechanism 6 includes a limiting rod 61, a locking component 64, and a first return spring 63. The locking component 64 also includes a pull plate 641, a plug rod 642, and a second return spring 644.

[0047] The limiting rod 61 is U-shaped, with the bottom of the limiting rod 61 passing through the slide body 12 and engaging with the sliding block 11. A limiting ring 62 is fixedly installed on the outer side of the limiting rod 61, and a first return spring 63 is sleeved on the outer side of the limiting rod 61 and located between the limiting ring 62 and the slide body 12. The first return spring 63 drives the limiting rod 61 to always tend to return to the sliding block 11.

[0048] The pull plate 641 is fixedly installed on the limiting rod 61, and the insertion rod 642 is telescopically installed on the pull plate 641. The second return spring 644 is sleeved on the insertion rod 642, and the second return spring 644 drives the insertion rod 642 to always tend to extend out of the pull plate 641. The slide body 12 has an insertion slot 643, and the insertion rod 642 can be movably inserted into the insertion slot 643.

[0049] In this embodiment, in order to unlock the limiting rods 61 on both sides of the skateboard body 12 at the same time, the limiting rods 61 on both sides are connected and fixed by the same pull plate 641.

[0050] When unlocking the sliding block 11, the limiting rod 61 is lifted upwards by pulling the lever. At this time, the lower end of the limiting rod 61 can disengage from the sliding block 11, allowing the sliding block 11 to move relative to the skateboard body 12. After the limiting rod 61 moves upwards, the insertion rod 642 and the insertion slot 643 are aligned. At this time, the insertion rod 642 can be inserted into the insertion slot 643 under the elastic force of the second return spring 644, thereby locking the limiting rod 61 and preventing it from being reinserted when the sliding block 11 is pushed out.

[0051] After the sliding block 11 is replaced, the plug rod 642 is pulled out from the plug slot 643. At this time, the first reset spring 63 can drive the bottom of the limit rod 61 to re-insert the sliding block 11, thereby re-locking the sliding block 11 and the slide body 12.

[0052] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
