Description

Technical Field

[0001] This utility model relates to the field of milling machine technology, specifically a cooling device for a mold production milling machine. Background Technology

[0002] In the field of mold making, milling machines are crucial equipment, as their machining accuracy and efficiency directly affect mold quality and production cycle. When workpieces are machined on a milling machine, coolant must be continuously sprayed to cool them and remove chips.

[0003] Traditional milling machine cooling devices typically use nozzles directly fixed to the side of the spindle or worktable with bolts or clamps. Each time the nozzle spray angle is adjusted, the operator must first loosen the fixing bolts, manually align them to the target position, and then tighten them again. This process requires repeated use of tools, is time-consuming for each adjustment, and affects the continuity of processing. Therefore, we propose a cooling device for milling machines used in mold production. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a cooling device for a milling machine used in mold production.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A cooling device for a milling machine used in mold production includes a coolant tank, a pumping pipeline, and a nozzle. The nozzle is mounted on the side of the milling machine spindle via an angle adjustment mechanism. The angle adjustment mechanism includes a mounting base, a support rod, a fixed ball, a fixed sleeve, a pressure block, an adjusting block, and an adjusting screw. The mounting base is fixed to the side wall of the milling machine spindle. The support rod is fixed to the outside of the pumping pipeline, with a fixed ball at one end. The fixed sleeve is fixed to the outside of the mounting base, with the fixed ball embedded in the fixed sleeve and rotatably connected to the inner wall of the fixed sleeve end. A gap is left between the fixed sleeve and the mounting base, and the adjusting block is slidably disposed within this gap. The pressure block is slidably fitted inside the fixed sleeve, with an arc-shaped groove on its side near the fixed ball that mates with the spherical surface of the fixed ball. The pressure block and the adjusting block slide together via an inclined structure, and the forward and backward movement of the adjusting block drives the pressure block to axially press the fixed ball to lock the angle of the support rod. One end of the adjusting screw is rotatably connected to the adjusting block, and the other end passes through the support plate of the mounting base and is fixedly provided with a handle, and is threadedly connected to the support plate.

[0006] Preferably, the inclined surface where the pressure block and the adjusting block meet is a double-inclined surface structure.

[0007] Preferably, the arc-shaped groove is coated with a wear-resistant and anti-slip layer.

[0008] Preferably, the wear-resistant and anti-slip layer also covers the contact surface between the fixed ball and the fixed sleeve.

[0009] Preferably, the inner wall of the fixed sleeve end is provided with an annular limiting flange, the inner diameter of which is smaller than the diameter of the fixed ball.

[0010] Preferably, the surface of the throttle handle of the adjusting screw is provided with anti-slip texture.

[0011] Preferably, the area between the pumping pipeline and the coolant tank and the support rod fixing point is a plastic hose.

[0012] Preferably, a self-lubricating coating is provided on the inclined surface where the adjusting block and the pressure block meet.

[0013] Preferably, the inclined surface where the pressure block and the adjusting block meet further includes a T-shaped guide rail structure.

[0014] Preferably, the support rod and the fixed ball are integrally formed.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This device achieves tool-free, rapid adjustment through an innovative angle adjustment mechanism (rotational connection between the fixed ball and the fixed sleeve, inclined engagement between the pressure block and the adjusting block, and an adjusting screw with a handle). The operator only needs to rotate the handle with one hand to drive the adjusting block to slide back and forth via the adjusting screw. The inclined structure pushes the pressure block against the fixed ball to lock or loosen the mechanism. When loosened, the support rod can rotate freely to precisely position the nozzle's spray direction; when locked, the pressure block axially presses against the fixed ball to ensure stability. This design simplifies complex bolt adjustments to a single-handed rotation operation, significantly reducing adjustment time and effectively ensuring smooth processing. The locking mechanism of this device achieves multi-dimensional stable locking through a tight fit between the pressure block's arc-shaped groove and the spherical surface of the fixed ball, combined with a wear-resistant and anti-slip layer and an annular limiting flange. The adjusting block drives the pressure block to apply uniform clamping force to the fixed ball along the axial direction, while the double-sloping surface structure or T-shaped guide rail structure further enhances force transmission stability and fitting accuracy. The wear-resistant and anti-slip layer reduces wear and slippage during long-term use, and the limiting flange prevents the fixed ball from dislodging. These designs collectively ensure that the nozzle angle remains highly stable even under the intense vibrations generated by high-speed milling, guaranteeing a continuous and precise spray of coolant to the machining area. The pumping pipeline uses a plastic hose between the coolant tank and the support rod fixing point, which can adapt to the flexible deformation when the support rod angle is adjusted, and is also corrosion resistant.

The basic principles of the present invention defined in the following description can be used in other embodiments, modifications, improvements, equivalents, and other technical solutions that do not depart from the spirit and scope of the present invention.

They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, the above terms should not be construed as limitations on this utility model.

[0022] It is understood that the term "a" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element can be one, while in another embodiment, the number of the element can be multiple, and the term "a" should not be understood as a limitation on the number. Example

[0023] Please see Figure 1-6A cooling device for a milling machine used in mold production includes a coolant tank 1, a pumping pipeline 2, and a nozzle 3. The nozzle 3 is mounted on the side of the milling machine spindle via an angle adjustment mechanism 4. The angle adjustment mechanism 4 includes a mounting base 5, a support rod 6, a fixed ball 7, a fixed sleeve 8, a pressure block 9, an adjusting block 10, and an adjusting screw 11. The mounting base 5 is fixed to the side wall of the milling machine spindle. The support rod 6 is fixed to the outside of the pumping pipeline 2, and a fixed ball 7 is provided at one end of the support rod, allowing the nozzle 3 to have omnidirectional adjustment freedom. The fixed sleeve 8 is fixed to the outside of the mounting base 5, and the fixed ball 7 is embedded in the fixed sleeve 8 and is in contact with the fixed sleeve. The inner wall of the 8 end is rotatably connected; a gap is left between the fixed sleeve 8 and the mounting base 5, and the adjusting block 10 is slidably disposed in the gap; the pressure block 9 is slidably fitted into the inside of the fixed sleeve 8, and an arc groove 13 that mates with the spherical surface of the fixed ball 7 is provided on the side near the fixed ball 7; the pressure block 9 and the adjusting block 10 are slidably engaged through the inclined structure, and the back and forth movement of the adjusting block 10 drives the pressure block 9 to axially press the fixed ball 7 to lock the angle of the support rod 6; one end of the adjusting screw 11 is rotatably connected to the adjusting block 10, and the other end passes through the support plate of the mounting base 5 and is fixedly provided with a handle 12, and is threadedly connected to the support plate.

[0024] The mating slope between the pressure block 9 and the adjusting block 10 is a double-sloped structure, which ensures that the driving force is symmetrically transmitted to both sides of the pressure block 9, eliminating the risk of jamming caused by unilateral load. The double slope increases the contact area, improves the linear accuracy of the axial movement of the pressure block 9, ensures that the fixed ball 7 bears uniform clamping force, and avoids local wear.

[0025] Meanwhile, the arc-shaped groove 13 is coated with a wear-resistant and anti-slip layer 16, which directly enhances the static friction between the pressure block 9 and the fixed ball 7, suppressing micro-displacement caused by vibration. The wear-resistant and anti-slip layer 16 further covers the surface of the fixed ball 7 and the inner wall of the fixed sleeve 8, forming full-area friction pair protection: it reduces the wear of the ball hinge joint, and improves the locking reliability through friction-enhancing properties, extending the life of key moving parts.

[0026] In this technical solution, the inner wall of the end of the fixed sleeve 8 is provided with an annular limiting flange 14, the inner diameter of which is smaller than the diameter of the fixed ball 7, forming a mechanical stop. When the adjusting block 10 is fully released, the flange still restricts the axial degree of freedom of the fixed ball 7, preventing the nozzle 3 from accidentally falling off due to gravity or vibration, and ensuring operational safety.

[0027] In this technical solution, the area between the pumping pipeline 2 and the coolant tank 1 and the fixed point of the support rod 6 is made of plastic flexible tubing, which has three functions: 1. Flexibility to adapt to the multi-angle deflection of the support rod 6; 2. Resistance to chemical corrosion of the coolant; 3. Buffering the impact of spindle vibration on the pipeline. Its combination with the rigid support rod 6 achieves an optimized force transmission path of "local flexibility - overall rigidity".

[0028] It is worth noting that the inclined surface where the adjusting block 10 and the pressure block 9 meet is provided with a self-lubricating coating, which reduces the friction coefficient of the double inclined sliding pair, eliminates dry friction noise, and makes the adjustment process smoother. This also reduces the generation of metal wear particles during long-term use and maintains the efficiency of locking force transmission.

[0029] In this technical solution, the inclined surface of the mating block 9 and the adjusting block 10 further includes a T-shaped guide rail structure 15, which not only restricts the circumferential displacement of the pressure block 9 and ensures its precise movement along the axis of the fixed sleeve 8, but also increases the shear strength of the contact surface to prevent locking failure caused by misalignment of the inclined surface under vibration.

[0030] Furthermore, the support rod 6 and the fixed ball 7 are integrally molded, eliminating the risks of thread loosening or welding fatigue associated with traditional split connections, and improving the bending and torsional stiffness of the ball head area. The integral structure prevents coolant from seeping into the connection gaps, extending the service life of the components in corrosive environments.

[0031] The working principle of this device is as follows: Rotating the handle 12 at the end of the adjusting screw 11 counterclockwise causes the screw to disengage from the support plate of the mounting base 5 via threaded transmission, pulling the adjusting block 10 to slide backward. As the adjusting block 10 moves backward, its double-sloped structure or the sloping surface with the T-shaped guide rail disengages from the mating surface of the pressure block 9, and the pressure block 9 loses its axial thrust. The pressure block 9 retracts within the fixed sleeve 8, releasing the clamping force between its arc groove 13 and the fixed ball 7. At this time, the fixed ball 7 can rotate freely within the fixed sleeve 8, driving the support rod 6 and the nozzle 3 to achieve omnidirectional angle adjustment. Rotating the handle 12 clockwise pushes the adjusting screw 11 forward, driving the adjusting block 10 to slide forward. The inclined surface of the adjusting block 10 presses against the corresponding inclined surface of the pressure block 9. Guided by the double inclined surface / T-shaped guide rail, the horizontal thrust is converted into the axial movement of the pressure block 9. The pressure block 9 moves towards the fixed ball 7, and the wear-resistant and anti-slip layer 16 in its arc groove 13 tightly adheres to the surface of the fixed ball 7, applying uniform axial pressure. This pressure forces the fixed ball 7 to generate strong friction with the inner wall of the fixed sleeve 8, instantly locking the angle of the support rod 6. In the locked state, the axial pressing force of the pressure block 9 on the fixed ball 7, the friction-enhancing effect of the wear-resistant and anti-slip layer 16, and the mechanical constraint of the limiting flange 14 form a triple anti-vibration mechanism to resist the vibration of milling machine processing.

[0032] Coolant is pumped from coolant tank 1 into pumping line 2, and the liquid flows through plastic hose into the internal channel of rigid pipe section; the liquid is sprayed out from nozzle 3 at the end of support rod 6. Because the angle of nozzle 3 has been precisely locked by the above mechanism, the coolant continuously covers the milling area. Example

[0033] In this technical solution, the surface of the handle 12 of the adjusting screw 11 is provided with anti-slip texture (not shown in the attached figure), which increases the friction of the operator's hand, especially in a humid environment where coolant splashes, to ensure that the adjustment force is stable and controllable, and to avoid loss of adjustment accuracy or safety accidents caused by slippage.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The purpose of the present invention has been fully and effectively achieved. The functions and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
