Description

Technical Field

[0001] This invention belongs to the field of bolt processing cooling technology, and specifically relates to a bolt processing cooling device. Background Technology

[0002] Bolts are widely used in aircraft wheel braking systems. During bolt processing, the cooling process directly affects the material's microstructure, mechanical properties, and dimensional stability. For aerospace fasteners in particular, rapid and uniform cooling after high-temperature quenching or heat treatment is crucial. This can effectively suppress internal grain coarsening, reduce residual stress, and prevent deformation or cracking caused by temperature gradients. Cooling efficiency and uniformity directly determine the bolt's fatigue strength, high-temperature creep resistance, and long-term reliability. This is especially critical for bolts in aircraft wheel braking systems that withstand extreme conditions. Therefore, specialized bolt processing cooling devices are usually used.

[0003] Existing bolt processing cooling devices mostly employ static immersion or fixed spraying methods. Static immersion involves directly immersing the bolt in a coolant tank, relying on natural convection for heat dissipation. However, the coolant flow rate is low and unevenly distributed, resulting in an excessive temperature gradient between the bolt surface and its core, which can easily lead to residual thermal stress. Linear spraying uses high-pressure nozzles to directionally scour the bolt surface, which can improve the local cooling rate, but the fixed spray angle makes it difficult to cover the entire circumference of the bolt, and the stationary workpiece can easily create stagnant zones in the liquid flow. All of these methods are relatively limited. Therefore, we propose a bolt processing cooling device. Summary of the Invention

[0004] In view of this, the present invention provides a bolt processing cooling device, which can significantly enhance the heat exchange efficiency between the coolant and the bolt surface by combining the up-and-down swaying and rotational combined motion of the bolt loading cylinder with the high-flow-rate vortex coolant synchronously sprayed by the spraying component, thereby greatly improving the cooling speed and effect, shortening the processing cycle and ensuring product quality.

[0005] To solve the above-mentioned technical problems, the present invention provides a bolt processing cooling device, including a cooling box and a cooling mechanism disposed therein. The cooling mechanism includes fixed cylinders symmetrically arranged at both ends of the bottom of the cooling box, each fixed cylinder having a sliding frame slidably connected inside. A bolt loading cylinder is rotatably connected between the two sliding frames. Both ends of the cooling box are also provided with spraying components for cooling the bolts. The upper end of the cooling box is also provided with a conveying component for guiding and conveying the cooled bolts. That is, through the combined up-and-down swaying and rotational motion of the bolt loading cylinder, combined with the high-flow-rate vortex coolant synchronously sprayed by the spraying components, the heat exchange efficiency between the coolant and the bolt surface is significantly enhanced, thereby greatly improving the cooling speed and effect, shortening the processing cycle and ensuring product quality.

[0006] The cooling mechanism also includes a rectangular cylinder located at the lower middle of the cooling box. An adjusting frame is slidably connected inside the rectangular cylinder. The outer arc surface of the bolt loading cylinder is rotatably connected to the inner arc surface of the adjusting frame. An electric telescopic rod is installed inside the rectangular cylinder. The electric telescopic rod is fixedly connected to the top of the rectangular groove at the lower end of the adjusting frame, thus achieving the function of lifting.

[0007] The cooling mechanism also includes a mounting port located on one side of the upper end of the adjustment frame. A gear is rotatably connected inside the mounting port. A toothed ring is located on the outer arc surface of the inner cavity of the adjustment frame near the gear. The toothed ring meshes with the gear. A motor is installed on the adjustment frame. The output shaft of the motor is fixedly connected to one end of the gear, which provides a drive source for the bolt loading cylinder.

[0008] The liquid spraying assembly includes a rotating tube symmetrically connected to both ends of the cooling tank. A transmission tube is installed in the liquid outlet hole at the inner end of the outer arc surface of the rotating tube. Several liquid outlets are distributed on the outer arc surface of the transmission tube near the bolt loading cylinder. Both ends of the bolt loading cylinder are equipped with a synchronous transmission assembly for driving the rotating tube to rotate synchronously, which serves as the function of liquid jetting.

[0009] The transmission pipes are all vortex-shaped, which ensures that the sprayed coolant can be evenly distributed.

[0010] The liquid spraying assembly also includes rotating caps respectively located at the outer ends of the rotating tube. The rotating tube is provided with several distributed liquid inlets on the outer arc surface of the inner cavity of the rotating cap. Liquid pumps are provided at both ends of the bottom of the inner cavity of the cooling box. The liquid outlet pipes of the liquid pumps penetrate through the outer surface of the cooling box and extend to the outside. The liquid outlet ends of the liquid outlet pipes are respectively connected to the liquid inlet ends of the adjacent rotating caps on the same side, which serves to transmit coolant.

[0011] The synchronous transmission assembly includes connectors respectively located at the inner ends of the rotating tube, and U-shaped connecting seats at both ends of the bolt loading cylinder. The U-shaped connecting seats are movably engaged with the adjacent connectors on the same side, thus achieving the function of rapid transmission.

[0012] The conveying assembly includes fixed plates symmetrically arranged at both ends of the upper part of the cooling box. Each fixed plate is provided with a sliding groove that slopes downward from back to front. A guide plate is slidably connected between the two sliding grooves to achieve efficient unloading.

[0013] The conveying assembly also includes a limiting plate located at the lower end of the guide plate near the cooling box, which serves to limit the movement of the guide plate.

[0014] It also includes a magnetic adsorption component, which includes mounting seats symmetrically arranged at both ends of the outer arc surface of the bolt loading cylinder. A magnetic roller is rotatably connected between the two mounting seats at each end, which can continuously adsorb iron impurities in the coolant.

[0015] The beneficial effects of the above-described technical solution of the present invention are as follows:

[0016] 1. The relevant operators add an appropriate amount of coolant to the cooling tank, then open the cover plate of the bolt loading cylinder, and feed the bolts that need to be cooled into the bolt loading cylinder. The cover plate is then reset and locked. The angle of the bolt loading cylinder is adjusted to align the synchronous transmission components. The electric telescopic rod then starts, its telescopic end retracting to move the adjusting frame and its auxiliary mechanisms downwards. Simultaneously, the sliding frame slides relative to the fixed cylinder until the bolt loading cylinder and its auxiliary mechanisms are immersed in the coolant, causing the synchronous transmission components to engage. After this, the electric telescopic rod starts again, its telescopic end moving up and down reciprocating to move the bolt loading cylinder. The loading cylinder oscillates up and down, while the motor starts and drives the gear to mesh with the toothed ring, causing the bolt loading cylinder to rotate continuously. During this process, the synchronous transmission component rotates along with the bolt loading cylinder, and simultaneously the rotating tube, transmission tube, and liquid outlet rotate coaxially with the bolt loading cylinder. At the same time, the liquid pump operates to send coolant into the rotating tube through the liquid inlet of the rotating cap. Through the combined motion of the bolt loading cylinder's up-and-down oscillation and rotation, combined with the high-flow-rate vortex coolant synchronously sprayed by the liquid spraying component, the heat exchange efficiency between the coolant and the bolt surface is significantly enhanced, thereby greatly improving the cooling speed and effect, shortening the processing cycle, and ensuring product quality.

[0017] 2. The lower openings of the U-shaped connecting seats at both ends of the bolt loading cylinder are precisely aligned with the connectors at the ends of the rotating tube. Then, the bolt loading cylinder moves down, causing the U-shaped connecting seats to engage with the connectors. As the bolt loading cylinder continues to rotate, the U-shaped connecting seats rotate with the bolt loading cylinder and simultaneously rotate coaxially with the rotating tube, transmission tube, and liquid outlet through the connectors.

[0018] 3. After the draining is completed, the operator raises the guide plate and slides it backward along the groove of the fixed plate to the designated position. Then, the guide plate is lowered so that the limiting plate at its end is precisely engaged inside the opening of the cooling box to form a smooth discharge path. At this time, the guide plate is tilted. Then, the bolt loading cylinder is rotated and the cover plate is opened so that the cooled bolts slide out automatically along the guide plate to achieve efficient unloading.

[0019] 4. The magnetic roller continuously adsorbs iron impurities in the coolant during bolt loading, maintaining the cleanliness of the cooling medium and further optimizing the cooling quality. Attached Figure Description

Detailed Implementation

[0027] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of the present invention. Figure 1-6 The technical solutions of the embodiments of the present invention will be clearly and completely described herein. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention are within the scope of protection of the present invention.

[0028] This embodiment provides a bolt processing cooling device, such as... Figure 1-6The cooling system includes a cooling tank 100 and a cooling mechanism disposed therein. The cooling mechanism includes fixed cylinders 200 symmetrically arranged at both ends of the bottom of the cooling tank 100. Sliding frames 201 are slidably connected inside each fixed cylinder 200. A bolt loading cylinder 202 is rotatably connected between two sliding frames 201. The outer arc surface of the bolt loading cylinder 202 has evenly distributed openings, and cover plates are hinged to both ends of the outer arc surface. The cover plates are fixedly connected to the bolt loading cylinder 202 by bolts. Both ends of the cooling tank 100 are also equipped with liquid spraying assemblies for cooling the bolts. The upper end of the cooling tank 100 is also equipped with a conveying assembly for guiding and transporting the cooled bolts. The cooling mechanism also includes a rectangular cylinder 203 disposed in the middle of the lower end of the cooling tank 100. An adjusting frame 204 is slidably connected inside a rectangular cylinder 203. The middle part of the outer arc surface of the bolt loading cylinder 202 is rotatably connected to the inner arc surface of the adjusting frame 204. An electric telescopic rod 205 is provided inside the rectangular cylinder 203. The electric telescopic rod 205 is fixedly connected to the top of the rectangular groove at the lower end of the adjusting frame 204. The cooling mechanism also includes an installation port 206 located on one side of the upper end of the adjusting frame 204. A gear 207 is rotatably connected inside the installation port 206. A toothed ring 208 is provided on the outer arc surface of the bolt loading cylinder 202 located in the inner cavity of the adjusting frame 204 near the gear 207. The toothed ring 208 is meshed with the gear 207. A motor 209 is provided on the adjusting frame 204. The output shaft of the motor 209 is fixedly connected to one end of the gear 207.

[0029] The operators add an appropriate amount of coolant to the cooling tank 100, then open the cover of the bolt loading cylinder 202, and feed the bolts that need to be cooled into the bolt loading cylinder 202. The cover is then reset and locked. The angle of the bolt loading cylinder 202 is adjusted to align the synchronous transmission components. Then, the electric telescopic rod 205 is activated, its telescopic end retracting to move the adjusting frame 204 and its auxiliary mechanisms downwards. Simultaneously, the sliding frame 201 slides relative to the fixed cylinder 200 until the bolt loading cylinder 202 and its auxiliary mechanisms are immersed in the coolant, causing the synchronous transmission components to engage. After this, the electric telescopic rod 205 is activated, its telescopic end moving up and down reciprocating, thereby causing the bolt loading cylinder 202 to sway up and down. Simultaneously, the motor 209 activates the drive gears. Wheel 207 meshes with toothed ring 208, causing bolt loading cylinder 202 to rotate continuously. During this process, the synchronous transmission component rotates along with bolt loading cylinder 202, and the spraying component rotates coaxially with bolt loading cylinder 202. Through the combined up-and-down swaying and rotational motion of bolt loading cylinder 202, combined with the high-flow-rate vortex coolant sprayed synchronously by the spraying component, the heat exchange efficiency between coolant and bolt surface is significantly enhanced, thereby greatly improving cooling speed and effect, shortening processing cycle and ensuring product quality. After cooling is completed, electric telescopic rod 205 extends fully, raising bolt loading cylinder 202 above the liquid surface to complete the draining. Then, the operator uses the conveying component to make the cooled bolts slide out automatically along guide plate 502, achieving efficient unloading.

[0030] like Figure 1-6 As shown, the liquid spraying assembly includes a rotating tube 300 symmetrically rotatably connected to both ends of the cooling tank 100. A transmission tube 301 is provided in the liquid outlet hole at the inner end of the outer arc surface of the rotating tube 300. Several liquid outlets 302 are provided on the outer arc surface of the transmission tube 301 near the bolt loading cylinder 202. Both ends of the bolt loading cylinder 202 are provided with synchronous transmission components for driving the rotating tube 300 to rotate synchronously. The transmission tubes 301 are all vortex-shaped structures. The liquid spraying assembly also includes a rotating cap 303 respectively provided at the outer end of the rotating tube 300. Several liquid inlets 304 are provided on the outer arc surface of the rotating tube 300 located in the inner cavity of the rotating cap 303. Liquid pumps 305 are provided at both ends of the bottom of the inner cavity of the cooling tank 100. The liquid outlet pipes of the liquid pumps 305 penetrate the outer surface of the cooling tank 100 and extend to the outside. The liquid outlet end of the liquid outlet pipe is connected to the liquid inlet end of the adjacent rotating cap 303 on the same side.

[0031] The rotating tube 300, the transmission tube 301, and the outlet 302 rotate coaxially with the bolt loading cylinder 202. At the same time, the liquid pump 305 operates to send coolant into the rotating tube 300 through the inlet 304 of the rotating cap 303, and spray it in the form of a jet stream through the outlet 302 of the vortex transmission tube 301, which significantly enhances the heat exchange efficiency between the coolant and the bolt surface.

[0032] like Figure 2-6 As shown, the synchronous transmission assembly includes connectors 400 respectively disposed at the inner ends of the rotating tube 300, and U-shaped connecting seats 401 are provided at both ends of the bolt loading cylinder 202. The U-shaped connecting seats 401 are movably engaged with the adjacent connectors 400 on the same side.

[0033] The lower openings of the U-shaped connecting seats 401 at both ends of the bolt loading cylinder 202 are precisely aligned with the connector 400 at the end of the rotating tube 300. Then, the bolt loading cylinder 202 moves down, so that the U-shaped connecting seats 401 and the connector 400 are engaged. When the bolt loading cylinder 202 continues to rotate, the U-shaped connecting seats 401 rotate with the bolt loading cylinder 202 and simultaneously rotate with the rotating tube 300, the transmission tube 301 and the liquid outlet 302 through the connector 400, coaxially rotating with the bolt loading cylinder 202.

[0034] like Figure 1-5 As shown, the conveying assembly includes fixed plates 500 symmetrically arranged at both ends of the upper part of the cooling box 100. Each fixed plate 500 is provided with a sliding groove 501 that is inclined downward from back to front. A guide plate 502 is slidably connected between the two sliding grooves 501. The conveying assembly also includes a limiting plate 503 arranged at the lower end of the guide plate 502 near the side of the cooling box 100. The middle part of the guide plate 502 is provided with an avoidance opening that is adapted to the adjusting frame 204.

[0035] After the draining is completed, the operator lifts the guide plate 502 upwards and slides it backwards along the groove 501 of the fixed plate 500 to the designated position. Then, the guide plate 502 is lowered so that the limiting plate 503 at its end is precisely engaged inside the opening of the cooling box 100, forming a smooth discharge path. At this time, the guide plate 502 is tilted. Then, the bolt loading cylinder 202 is rotated and the cover plate is opened so that the cooled bolts slide out automatically along the guide plate 502, achieving efficient unloading.

[0036] like Figure 2-4 As shown, it also includes a magnetic adsorption component, which includes mounting seats 600 symmetrically arranged at both ends of the outer arc surface of the bolt loading cylinder 202, and a magnetic roller 601 rotatably connected between the two mounting seats 600 at each end.

[0037] The magnetic roller 601 continuously adsorbs iron impurities in the coolant during bolt loading, maintaining the cleanliness of the cooling medium and further optimizing the cooling quality.

[0038] The working principle of the bolt processing cooling device provided by this invention is as follows: First, the relevant operator adds an appropriate amount of coolant to the cooling tank 100. Then, the cover plate of the bolt loading cylinder 202 is opened, and the bolts that need to be cooled are fed into the bolt loading cylinder 202. Then, the cover plate is reset and locked. Then, the angle of the bolt loading cylinder 202 is adjusted so that the lower opening of the U-shaped connecting seat 401 at both ends is precisely aligned with the connecting head 400 at the end of the rotating tube 300. Then, the electric telescopic rod 205 is started, and its telescopic end retracts, driving the adjusting frame 204 and its auxiliary mechanism to move down. At the same time, the sliding frame 201 moves synchronously with the fixed cylinder. The bolt loading cylinder 202 and its auxiliary mechanisms slide relative to each other until they are immersed in the coolant, causing the U-shaped connecting seat 401 to engage with the connecting head 400. After this, the electric telescopic rod 205 is activated, its telescopic end moving up and down reciprocally, thereby causing the bolt loading cylinder 202 to sway up and down. Simultaneously, the motor 209 activates the drive gear 207 to mesh with the toothed ring 208, causing the bolt loading cylinder 202 to rotate continuously. During this process, the U-shaped connecting seat 401 rotates along with the bolt loading cylinder 202, and simultaneously, through the connecting head 400, it links the rotating pipe 300, the transmission pipe 301, and the outlet 302 with the bolt loading cylinder. The loading cylinder 202 rotates coaxially. Simultaneously, the liquid pump 305 operates, sending coolant through the inlet 304 of the rotating cap 303 into the rotating tube 300. The coolant is then sprayed in a jet stream form through the outlet 302 of the vortex transmission tube 301. The combined up-and-down swaying and rotational motion of the bolt loading cylinder 202, along with the high-velocity vortex coolant sprayed synchronously from both rotating tubes 300, significantly enhances the heat exchange efficiency between the coolant and the bolt surface. This greatly improves the cooling speed and effect, shortens the processing cycle, and ensures product quality. Meanwhile, the magnetic roller 601 continuously adsorbs iron impurities from the coolant during bolt loading, maintaining the cooling medium... To improve the cleanliness of the liquid and further optimize the cooling quality, after cooling is complete, the electric telescopic rod 205 extends fully, raising the bolt loading cylinder 202 above the liquid surface to complete the draining. Then, the operator lifts the guide plate 502 upward and slides it backward along the sliding groove 501 of the fixed plate 500 to the designated position. Then, the guide plate 502 is lowered, so that the limiting plate 503 at its end is precisely engaged inside the opening of the cooling box 100, forming a smooth discharge path. At this time, the guide plate 502 is tilted. Then, the bolt loading cylinder 202 is rotated and the cover is opened, so that the cooled bolts slide out automatically along the guide plate 502, achieving efficient unloading.
