Description

Technical Field

[0001] This utility model relates to the technical field of horizontal lathe processing equipment, and more specifically to a double worktable quick exchange mechanism. Background Technology

[0002] The dual-table quick-change mechanism enables machine tools to exchange two worktables, meaning that while one worktable is being processed, a part can be clamped on another worktable, and the worktable can be directly changed after processing is completed.

[0003] According to the publication (announcement) number: CN202527948U, the publication (announcement) date: 2012-11-14, a dual-worktable fast exchange mechanism is disclosed.

[0004] In the prior art, including the aforementioned patent, one of the worktables of a dual-worktable machine tool will inevitably generate certain waste chips and sparks during the processing. The other worktable is easily interfered with by the waste chips and sparks during the addition of new parts, which may cause damage to the parts to be processed. The existing technology can install a protective plate between the two worktables, but the protective plate is easy to interfere with the working area and affect the normal operation of the equipment, regardless of whether it is installed on a horizontally moving or rotating dual worktable. Utility Model Content

[0005] The purpose of this invention is to provide a dual-worktable rapid exchange mechanism to solve the problems mentioned above.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A dual-worktable quick-exchange mechanism includes a base and a platform and dual worktables disposed thereon, and also includes a boss mounted on the dual worktables. The boss has a recess, and a pit block is installed at the end of the recess to divide its internal space and form symmetrically arranged slides.

[0008] A partition is slidably installed in the slide, and a pull rope is fixedly installed on the partition, with a rope head that is threadedly connected to the base at the end of the pull rope.

[0009] Preferably, a section for containing cutting fluid is formed between the two partitions, and the partitions are further arranged in an array with sliding strips that cooperate with the section.

[0010] Preferably, the slide is divided by a partition to form an inner channel and an outer channel, the slide bar slides in the inner channel and is used to squeeze out the cutting fluid in the outer channel.

[0011] Preferably, the pit block has an inclined opening that connects to the inner channel.

[0012] Preferably, the outer port is fixedly equipped with an elastic strip that slides in cooperation with the partition.

[0013] In the above technical solution, the dual-worktable quick-exchange mechanism provided by this utility model has the following beneficial effects: when the dual worktables rotate or slide on the base, the distance between two points on the two worktables increases, that is, the connection position between the hole of the pull rope extending out of the base and the rope end. Therefore, the rope end fixed by the threaded connection of the base pulls the pull rope, thereby compressing the spring on the partition and retracting it into the slide. This enables the dual worktables to store and protect the partition during adjustment, avoiding interference from the partition in the working area. In the default state, the two partitions form a double barrier protection, effectively preventing the erosion and damage to the parts to be processed by waste chips and sparks, and ensuring the processing efficiency of the parts.

[0021] 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.

[0022] like Figure 1-4As shown, a dual-worktable quick exchange mechanism includes a base 1 and a platform 20 and a dual-worktable 2 disposed thereon, and also includes a boss 3 installed on the dual-worktable 2. The boss 3 has a recess 30, and a pit block 31 is installed at the port of the recess 30 to divide its internal space and form a symmetrically arranged slide rail 32.

[0023] A partition 4 is slidably arranged in the slide 32, and a pull rope 41 is fixedly installed on the partition 4. The end of the pull rope 41 is fixedly installed with a rope head 42 that is threadedly connected to the base 1.

[0024] Specifically, the base 20 is fixedly installed on the lower end face of the double worktable 2. The base 20 can rotate on the base 1 or slide on the base 1 to adapt to the usage range of the double worktable 2. Both installation methods with the base 1 are existing technologies and will not be described in detail here.

[0025] Furthermore, the boss 3 is fixed to the middle of the double worktable 2, and the connection between the two is rounded so that the sprayed cutting fluid flows to the drainage groove on the table surface to ensure the cleaning effect.

[0026] Furthermore, the pit block 31 can seal the recess 30 so that the two partitions 4 can slide in their respective slides 32, ensuring the blocking effect of the partitions 4. The lower end of the partition 4 is fixedly installed with multiple springs connected to the bottom of the recess 30. The pull rope 41 also passes through the bottom of the recess 30 and the base 20, and extends from the side of the base 20 so that the threaded block on the rope end 42 can be detachably and stably connected to the base 1.

[0027] When the double worktables 2 rotate or slide on the base 1, the distance between two points on them increases. This corresponds to the connection position between the hole where the pull rope 41 extends out of the base 20 and the rope end 42. Therefore, the rope end 42, which is fixed by the threaded connection of the base 1, pulls the pull rope 41, thereby compressing the spring on the partition 4 and retracting it into the slide rail 32. This allows the double worktables 2 to protect the partition 4 during adjustment, preventing the partition 4 from interfering with the work area. In the default state, the two partitions 4 form a double barrier protection, effectively preventing the erosion and damage to the parts to be processed by waste chips and sparks, and ensuring the efficiency of parts processing.

[0028] As a further embodiment of this utility model, a section 43 for containing cutting fluid is formed between the two partitions 4, and slide bars 44 that cooperate with the section 43 are also arranged in an array on the partitions 4.

[0029] Specifically, the partition 43 is the space between two partitions 4, and this space is filled with cutting fluid sprayed onto the workpiece, so that the partition 43 is filled with mist-like cutting fluid.

[0030] Furthermore, the slider 44 is specifically formed by bonding a sound-absorbing pad and a rubber pad together, and the material and adhesive used for the connection are existing technologies, which will not be elaborated here.

[0031] By setting up the partition 43, the resonance phenomenon generated by the machining of parts by the dual worktable 2 can be buffered. The cutting fluid filled in the partition 43 can reduce the propagation of resonance. In addition, the multiple slide bars 44 between the two partitions 4 can further absorb the resonance and avoid deformation damage to the workpiece.

[0032] As another embodiment further provided by this utility model, the slide 32 is divided by the partition 4 to form an inner channel 321 and an outer channel 322, and the slide bar 44 slides in the inner channel 321 and is used to squeeze out the cutting fluid in the outer channel 322.

[0033] Specifically, when the partition 4 slides down and is stored in the slide 32, the inner slide 321 and the outer slide 322 are responsible for the gas flow in the recess 30.

[0034] As the partition 4 moves downward, multiple sliders 44 sequentially enter the inner channel 321. As the sliders 44 slide against the side wall of the pit block 31, they function as piston plates. At the same time, multiple sliders 44 enhance the piston effect, allowing the gas and cutting fluid in the pit 30 to enter the outer channel 322 and be ejected from the upper port of the outer channel 322. The purpose is to spray out gas containing cutting fluid to flush the surface of the partition 4, effectively removing residual debris from the surface of the partition 4, ensuring the smooth retraction of the partition 4, and reducing damage to the partition 4.

[0035] As another embodiment further provided by this utility model, the pit block 31 is provided with an oblique opening 320 that connects to the inner channel 321.

[0036] Specifically, the bevels 320 are symmetrically arranged on the upper surface of the pit block 31, with the purpose of delivering the atomized cutting fluid equally from the two inner channels 321 into the recess 30 so that the cutting fluid can be sprayed out from the outer channel 322.

[0037] The atomized cutting fluid in the partition 43 is collected by the inclined port 320 and guided into the inner channel 321, which facilitates the collection and reuse of the cutting fluid.

[0038] As another embodiment provided in this utility model, an elastic strip 45 that slides with the partition 4 is fixedly installed at the outer channel 322 port.

[0039] Specifically, the elastic strip 45 is a rubber strip and is installed at the port of the recess 30, with the elastic strip 45 tilted towards the end face of the partition 4 where the slide bar 44 is not provided.

[0040] The elastic strip 45, which is inclined to the surface of the partition plate 4, can prevent the cutting fluid sprayed upward from the outer channel 322 port from flowing back. On the other hand, it also prevents the possibility of waste chips falling into the outer channel 322 from the surface of the partition plate 4. In the default state, the elastic strip 45 can also block the waste chips on the partition plate 4, ensuring the flow effect of gas and cutting fluid in the recess 30.

[0041] Working principle: When the double worktables 2 rotate or slide on the base 1, the distance between two points on them increases. This corresponds to the connection position between the hole where the pull rope 41 extends out of the base 20 and the rope end 42. Therefore, the rope end 42, which is fixed by the threaded connection of the base 1, pulls the pull rope 41, thereby compressing the spring on the partition 4 and retracting it into the slide rail 32. This allows the double worktables 2 to protect the partition 4 during adjustment, preventing the partition 4 from interfering with the working area. In the default state, the two partitions 4 form a double barrier, effectively preventing the erosion and damage to the parts to be processed by sparks and debris. Furthermore, the partition 43 can control the output of the parts processed by the double worktables 2. The vibration phenomenon is buffered, and the cutting fluid in the partition 43 can reduce the propagation of the vibration. In addition, the multiple sliding strips 44 between the two partitions 4 can further absorb the vibration. As the partition 4 moves down, the multiple sliding strips 44 enter the inner channel 321 in sequence. As the sliding strips 44 slide against the side wall of the pit block 31, the sliding strips 44 act as piston plates. At the same time, the multiple sliding strips 44 can enhance the piston effect, so that the gas and cutting fluid in the pit 30 can only enter the outer channel 322 and be sprayed out from the upper port of the outer channel 322. The purpose is to spray the gas with cutting fluid to flush the surface of the partition 4 and effectively remove the residual and attached waste chips on the surface of the partition 4.

[0042] 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.
