Description

Technical Field

[0001] This utility model relates to the field of auxiliary equipment for mechanical processing, and in particular to a rapid cooling device for Chuck discs. Background Technology

[0002] In modern machining and automated production processes, the Chuck disc, as a key component for fixing and clamping workpieces, directly determines the quality of the final product through its stability and precision. Under prolonged, high-load, or high-speed rotational machining environments, the Chuck disc often accumulates heat due to internal mechanical friction and high-temperature conduction in the cutting area.

[0003] However, existing chucks typically lack efficient and easy-to-maintain active cooling solutions. Current common heat dissipation methods rely heavily on natural airflow or simple external fans. This passive cooling approach is inefficient and fails to quickly remove heat generated in the core area, leading to chuck deformation and affecting clamping accuracy or even damaging the equipment. While some high-end equipment is equipped with liquid cooling systems, these systems are usually structurally enclosed and use rigid connections. This not only fails to provide efficient, close-fitting heat exchange at the bottom of the chuck, but also makes the auxiliary cooling components on the sides difficult to disassemble quickly. These structural limitations result in extremely cumbersome, time-consuming, and labor-intensive operations when cleaning, repairing, or replacing the cooling system, failing to balance efficient cooling with ease of maintenance and failing to meet the dual demands of modern industry for processing efficiency and equipment maintainability.

[0004] Therefore, this invention proposes a rapid cooling device for Chuck discs to address the shortcomings of existing technologies. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rapid cooling device for Chuck discs, which aims to improve the problems of heat accumulation during Chuck disc operation leading to decreased processing accuracy and the inconvenience of disassembly and maintenance of existing cooling devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a rapid cooling device for a Chuck disc, comprising: a Chuck disc, wherein a retaining clip is fixedly connected to the side wall of the Chuck disc;

[0011] Preferably, the cooling mechanism further includes a connecting shell, the top of which is fixedly connected to the bottom edge of the Chuck disk.

[0012] Preferably, the cooling mechanism further includes a second cooling plate, which is fixedly connected inside the connecting shell.

[0013] Preferably, the cooling mechanism further includes a protective shell, which is fixedly connected above the second cooling plate, and the cooling pipe is disposed inside the protective shell.

[0014] Preferably, the cooling mechanism further includes a sealing plate, which is fixedly connected to the top of the protective shell, and the first cooling plate is fixedly connected above the sealing plate.

[0015] Preferably, the first connecting plate has a guide groove and a threaded groove, and the second connecting plate has a corresponding guide groove and a threaded groove that cooperate with the guide groove and the threaded groove.

[0029] 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.

[0030] Reference Figures 1-6 This utility model provides an embodiment of a rapid cooling device for a Chuck disc, comprising a Chuck disc 1 and a retaining housing 2 fixedly connected to the side wall of the Chuck disc 1. The Chuck disc 1 serves as the core load-bearing component of the entire device, while the retaining housing 2 provides a basic mounting interface for the side heat dissipation components. A heat dissipation plate 4 is detachably connected to the side wall of the retaining housing 2 via a disassembly and assembly mechanism 5, and a cooling mechanism 3 is tightly fixedly connected to the bottom of the Chuck disc 1.

[0031] The cooling mechanism 3 is the core component for achieving rapid cooling of the Chuck 1. The cooling mechanism 3 contains cooling pipes 306, which serve as channels for the circulation of the cooling medium, enabling efficient heat removal through the flow of the cooling medium. A first cooling plate 302 is located on the top of the cooling mechanism 3, and it fits tightly against the bottom of the Chuck 1, serving as the main interface for heat transfer from the Chuck 1 to the interior of the cooling mechanism 3, ensuring that the heat generated by the Chuck 1 can be efficiently transferred to the cooling pipes 306 for heat exchange.

[0032] The disassembly / assembly mechanism 5 is a key structure for enabling the rapid disassembly and installation of the heat sink 4. The disassembly / assembly mechanism 5 includes a first connecting plate 501 and a second connecting plate 502. The first connecting plate 501 and the second connecting plate 502 cooperate with each other and can move relative to each other to achieve the connection and separation between the heat sink 4 and the retaining housing 2. The disassembly / assembly mechanism 5 also includes a threaded post 504, which is the core component driving the relative movement of the first connecting plate 501 and the second connecting plate 502. Disassembly / assembly operations are achieved by rotating the threaded post 504. The disassembly / assembly mechanism 5 further includes a guide post 503, which precisely guides the relative movement trajectory of the first connecting plate 501 and the second connecting plate 502, ensuring the smoothness and accuracy of the disassembly / assembly process. In addition, a spring 505 is sleeved on the outer wall of the guide post 503. The spring 505 provides a buffering effect, generates pre-tightening force during connection to ensure the stable and reliable connection of the heat sink 4, and assists in the separation of the mechanism during disassembly to prevent jamming.

[0033] The cooling mechanism 3 has a connecting shell 301, the top of which is fixedly connected to the bottom edge of the Chuck 1. The connecting shell 301 serves as the outer shell and main support structure of the cooling mechanism 3. A second cooling plate 305 is fixedly connected inside the connecting shell 301. The second cooling plate 305 is used to enhance the heat transfer efficiency and structural stability inside the cooling mechanism 3.

[0034] The protective shell 304 is fixedly connected above the second cooling plate 305. The interior of the protective shell 304 forms a space for accommodating cooling pipes 306 that circulate the cooling medium. The cooling pipes 306 are arranged in a coiled or grid-like pattern inside the protective shell 304 to increase the contact area between the cooling medium and the protective shell 304, thereby improving heat exchange efficiency. Both ends of the cooling pipes 306 extend to the outside of the protective shell 304 and are connected to a cooling medium circulation system, such as a pump and a radiator, to facilitate the entry, exit, and circulation of the cooling medium.

[0035] The sealing plate 303 is fixedly connected to the top of the protective shell 304. The function of the sealing plate 303 is to form a sealed cavity to prevent the cooling medium from leaking from the inside of the cooling mechanism 3. It also serves as the mounting base for the first cooling plate 302. The first cooling plate 302 is tightly fixedly connected above the sealing plate 303 and is in direct and tight contact with the bottom of the Chuck 1. It serves as the main heat exchange interface for the heat from the Chuck 1 to be transferred to the inside of the cooling mechanism 3, ensuring that the heat generated by the Chuck 1 can be efficiently and quickly transferred to the first cooling plate 302, and then conducted to the cooling medium in the cooling pipe 306 through the sealing plate 303, the protective shell 304, and the second cooling plate 305.

[0036] This multi-layered plate structure combined with internal piping ensures that the heat from the Chuck 1 can be efficiently and evenly absorbed and conducted to the cooling medium, thereby achieving a rapid cooling effect. For the cooling medium circulation system, those skilled in the art can employ various conventional methods such as pumps, storage tanks, and external radiators; the specific internal structure of these systems is well-known in the field and will not be described in detail here.

[0037] In a preferred embodiment, the first connecting plate 501 of the disassembly and assembly mechanism 5 is provided with a guide groove 506 and a threaded groove 507, and the second connecting plate 502 is provided with a guide groove and a threaded groove that cooperate with the guide groove 506 and the threaded groove 507. This slotting design provides a precise trajectory for the movement of the threaded post 504 and the guide post 503, ensuring that the relative movement between the first connecting plate 501 and the second connecting plate 502 follows a preset path and preventing deviation or jamming.

[0038] In another preferred embodiment, the threaded post 504 is threadedly connected to the threaded groove 507 of the first connecting plate 501. The threaded post 504, through its own rotation, converts rotation into axial movement using the helix angle of its thread, thereby driving the first connecting plate 501 to move relative to the second connecting plate 502. The guide post 503 is slidably connected to the guide groove 506 of the first connecting plate 501. The guide post 503 ensures that the connecting plates remain aligned when the threaded post 504 drives the connecting plates to move, preventing misalignment due to uneven force or manufacturing tolerances.

[0039] In another preferred embodiment, spring 505 is sleeved on the outer wall of guide post 503, with its two ends abutting against the shoulder of guide post 503 and the end of guide groove 506 or a corresponding position on another connecting plate. When disassembly / reassembly mechanism 5 is in the locked state, spring 505 is in the compressed state, providing a stable preload for connection, ensuring the firmness of the connection between heat sink 4 and clip 2, and reducing vibration and loosening. When disassembly is required, the release force of spring 505 can assist in the separation of connecting plates, providing a buffering effect and avoiding impact.

[0040] Working principle: Chuck 1 is the main body, and the housing 2 is fixedly connected to the side wall of Chuck 1. The heat dissipation plate 4 is connected to the side wall of the housing 2 through the disassembly and assembly mechanism 5. The top of the connecting shell 301 is fixedly connected to the bottom of Chuck 1. The second cooling plate 305 is fixedly connected inside the connecting shell 301. The second cooling plate 305 is fixedly connected to the protective shell 304. The protective shell 304 is provided with a cooling pipe 306. The sealing plate 303 is fixedly connected to the top of the protective shell 304. The first cooling plate 302 is fixedly connected to the sealing plate 303. The first connecting plate 501 and the second connecting plate 502 are each provided with a guide groove 506 and a threaded groove 507. The threaded post 504 is threadedly connected inside the threaded groove 507. The guide post 503 is slidably connected inside the guide groove 506. The outer wall of the guide post 503 is fitted with a spring 505.

[0041] Working principle: When the Chuck 1 generates heat and needs cooling, cooling medium such as water, oil or special coolant is introduced into the cooling pipe 306. The heat generated by the Chuck 1 is first conducted through the bottom of the Chuck 1 to the first cooling plate 302 that is in close contact with it. The first cooling plate 302 then transfers the heat to the fixedly connected sealing plate 303. The sealing plate 303 then transfers the heat to the fixedly connected protective shell 304. The cooling pipe 306 inside the protective shell 304 absorbs the heat and carries it away through the circulation of the cooling medium. At the same time, the protective shell 304 also conducts the heat to the fixedly connected second cooling plate 305. The second cooling plate 305 further assists in the diffusion of heat to the fixedly connected connecting shell 301. The connecting shell 301 finally dissipates the heat. Simultaneously, the retainer 2 fixedly connected to the side wall of the Chuck 1 also absorbs heat and transfers the heat to the heat dissipation plate 4 connected through the disassembly and assembly mechanism 5. The heat dissipation plate 4 assists in passive heat dissipation. Through this combination of bottom active liquid cooling and side wall auxiliary heat dissipation, efficient and rapid cooling of the Chuck 1 is achieved.

[0042] When the heat sink 4 needs to be disassembled for maintenance or replacement, the operator rotates the threaded post 504 in the disassembly mechanism 5. The threaded post 504 rotates inside the threaded groove 507 on the first connecting plate 501 and the second connecting plate 502 and generates axial movement, driving the first connecting plate 501 and the second connecting plate 502 to move relative to each other. During the relative movement, the guide post 503 slides along the length of the guide groove 506 inside the guide groove 506 on the first connecting plate 501 and the second connecting plate 502, ensuring that the two connecting plates move smoothly and aligned. The spring 505 sleeved on the outer wall of the guide post 503 extends and retracts accordingly, providing separation elasticity during disassembly and pre-tightening force and buffering effect during installation and locking. Through this combination of threaded drive and guide buffering, convenient disassembly and assembly between the heat sink 4 and the retainer 2 is achieved.
