Description

Technical Field

[0001] The invention relates to the technical field of sawing cooling, and in particular to a high-efficiency cooling device for trimming of automobile parts. Background Art

[0002] When trimming the edges of automotive parts, trimming equipment is required. Common trimming equipment usually uses straight saw blades or circular saw blades, and trimmers in the form of circular saw blades are mainly used in the trimming of automotive parts. Due to the high-speed rotation and friction of the circular saw blade when trimming the automotive parts, a high temperature will be generated, resulting in poor trimming effect. For this reason, staff usually spray coolant on the surface of the circular saw blade when trimming, and then cool the circular saw blade to achieve the purpose of effective trimming.

[0003] In practice, in order to save costs and water resources, intermittent spraying of coolant is usually used during edge cutting. However, when automotive parts are larger, harder or thicker, the edge cutting time and the intensity of the circular saw blade also increase, and the circular saw blade may overheat. The current cooling device is not convenient for switching intermittent spraying to continuous spraying according to the situation, which leads to low cooling efficiency of the circular saw blade. In addition, the existing cooling device is not convenient for increasing the water pressure while increasing the water volume, which leads to insufficient cooling of the circular saw blade, thus affecting the cooling effect. Summary of the invention

[0004] In order to overcome the above-mentioned shortcomings, the present invention provides a high-efficiency cooling device for trimming automotive parts, which can switch the spray mode to improve the cooling efficiency when the circular saw blade is overheated, and can increase the water volume of the coolant while increasing the water pressure to make the cooling of the circular saw blade more thorough, thereby enhancing the cooling effect.

[0015] As a preferred technical solution of the present invention, the reciprocating assembly includes: a bidirectional threaded sleeve fixedly connected to the transmission shaft; a threaded rod threadedly connected to the bidirectional threaded sleeve; a piston rod fixedly connected to one end of the threaded rod and slidably connected to the piston cylinder, one end of the piston rod being in contact with the inner wall of the piston cylinder.

[0016] As a preferred technical solution of the present invention, it also includes a refrigeration plate installed on the piston cylinder.

[0017] As a preferred technical solution of the present invention, it also includes a reinforcement mechanism for increasing the flow rate of the coolant under high strength conditions, which is arranged on the cooling box, the one-way valve and the outer frame, and the reinforcement mechanism includes: a pipe two connected to the bottom of the cooling box; a transfer pipe installed at the bottom end of the pipe two, a cavity and a lock cavity are opened in the transfer pipe, and the cavity of the transfer pipe is connected to the pipe two; an empty slot pipe installed on another one-way valve one, one end of which is connected to the external air; a U-shaped pipe slidably connected between the transfer pipe and the empty slot pipe; a pull rod installed on the U-shaped pipe and passing through the outer frame.

[0020] The present invention has the following advantages: 1. The present invention drives the circular saw blade to rotate through a motor, and the staff holds the horizontal handle and the vertical handle with both hands to push the device to move, so that the rotating circular saw blade contacts the automobile parts and performs edge cutting; the rotation of the transmission shaft drives the rotation of the bidirectional threaded sleeve so that the threaded rod and the piston rod move back and forth laterally together, and then the coolant is intermittently pushed into the infusion stand, and the coolant in the infusion stand will enter the liquid outlet cavity.

[0021] 2. The staff can pull the pull rod to move the U-tube according to the situation. The movement of the U-tube will connect the transfer tube with the empty slot tube and block the connection between the empty slot tube and the outside air. In this way, the head of the piston rod will divide the inside of the piston cylinder into two independent chambers. When the piston rod pushes out the coolant in one of the chambers, it will simultaneously suck the coolant into the other chamber. Then, when the piston rod reciprocates, the coolant will continuously and uninterruptedly be pushed out of the piston cylinder, so that the coolant will continuously adhere to the circular saw blade for cooling, thereby cooling the circular saw blade more quickly, thereby improving the cooling efficiency.

[0022] 3. The movement of the pull rod drives the pull ring to pull the two limit frames to move. The four inclined grooves squeeze the four protrusions respectively to make the two pressure blocks move towards each other, thereby reducing the size of the liquid outlet cavity. With the same amount of water and the effect of reducing the outlet, the water pressure of the cooling water sprayed on the surface of the circular saw blade can be increased, so that the coolant can be more fully attached to the circular saw blade, thereby cooling the circular saw blade more thoroughly, thereby enhancing the cooling effect.

DETAILED DESCRIPTION

[0041] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] Embodiment 1: A highly efficient cooling device for trimming automotive parts, such as Figure 1-Figure 16 As shown, including:

[0043] External frame 101;

[0044] The support base 102 is welded to one side of the inner bottom of the outer frame 101;

[0045] A cooling box 103 with a loading port on the top is installed on one side of the top of the outer frame 101 and is used to load the coolant;

[0046] The horizontal handle 21 and the vertical handle 22 installed on the outer frame 101 are used to push the outer frame 101 when trimming the automotive parts;

[0047] The driving mechanism is arranged on the outer frame 101 and the support seat 102, and the circular saw blade 0 is installed on the driving mechanism. The driving mechanism is used to drive the circular saw blade 0 to rotate at a high speed to cut the edges of the automobile parts;

[0048] The cooling mechanism is used to cool the circular saw blade 0 and is arranged on the support base 102 , the outer frame 101 and the cooling box 103 .

[0049] The driving mechanism includes: a motor 31, which is installed on a support seat 102; a transmission shaft 32 installed on the output shaft of the motor 31, with a liquid passage groove 321 opened inside one side, and two liquid inlet grooves 322 extending from the liquid passage groove 321 to the outside of the transmission shaft 32; a saw blade shaft 33 connected to the transmission shaft 32 through a coupling, for installing a circular saw blade 0, and a threaded groove is opened at one end of the saw blade shaft 33 away from the transmission shaft 32; a circular saw blade 0 slidably connected to the saw blade shaft 33; a threaded cap 34 threadedly connected to the threaded groove of the saw blade shaft 33, for limiting the circular saw blade 0 and contacting the circular saw blade 0.

[0050] The saw blade shaft 33 has a second liquid passage groove 331 and a liquid outlet cavity 332 formed therein, and the second liquid passage groove 331 is communicated with the first liquid passage groove 321 and the liquid outlet cavity 332 respectively.

[0051] The cooling mechanism includes: a piston cylinder 41 connected to the support seat 102 by bolts, located on one side of the motor 31; one-way valves 42 respectively installed on both sides of the top of the piston cylinder 41, and both are connected to the inside of the piston cylinder 41; one-way valves 42 respectively installed on both sides of the bottom of the piston cylinder 41, and both are connected to the inside of the piston cylinder 41; a pipe 44 installed on one of the one-way valves 42, and the other end of the pipe 44 is connected to the cooling box 103; a three-head pipe 45 is connected between the two one-way valves 43; an infusion stand 46 installed on the inner bottom of the outer frame 101 and rotatably connected to the transmission shaft 32, the infusion stand 46 is connected to the two liquid inlet grooves 322, and the other end of the three-head pipe 45 is connected to the infusion stand 46; a reciprocating assembly provided on the transmission shaft 32 and the piston cylinder 41, used to drive the flow of coolant.

[0052] The reciprocating assembly includes: a bidirectional threaded sleeve 471 connected to the transmission shaft 32 through a flat key; a threaded rod 472 connected to the bidirectional threaded sleeve 471 through a thread; a piston rod 473 welded to one end of the threaded rod 472 and slidably connected to the piston cylinder 41, and one end of the piston rod 473 contacts the inner wall of the piston cylinder 41.

[0053] A refrigeration plate 7 is also included, which is installed on the piston cylinder 41 and is used to further cool the coolant in the piston cylinder 41 .

[0054] When it is necessary to install the circular saw blade 0, the staff first unscrews the threaded cap 34 from the saw blade shaft 33, and then installs the circular saw blade 0 to be used on the saw blade shaft 33, and then the staff twists the threaded cap 34 back onto the saw blade shaft 33 to fix the circular saw blade 0; when it is necessary to trim the automotive parts, the staff first places the device and the automotive parts to be trimmed on the corresponding workbench, and then the staff starts the motor 31. The output shaft of the motor 31 rotates to drive the transmission shaft 32, the saw blade shaft 33, the threaded cap 34 and the circular saw blade 0 to rotate synchronously. At this time, the staff can hold the two ends of the saw blade shaft 33 with both hands. The horizontal handle 21 and the vertical handle 22 are used to push the device to move, so that the rotating circular saw blade 0 contacts the automobile parts and performs trimming. Before trimming the automobile parts, the staff first pours the prepared coolant into the cooling box 103 through the loading port. When trimming the automobile parts, the rotation of the transmission shaft 32 drives the two-way threaded sleeve 471 to rotate. The rotation of the two-way threaded sleeve 471 drives the threaded rod 472 and the piston rod 473 to move back and forth horizontally. The reciprocating movement of the piston rod 473 first passes through one of the one-way valves 42 and the pipeline 44 to The coolant in the cooling box 103 is sucked into the piston cylinder 41, and then the piston rod 473 will push the coolant sucked into the piston cylinder 41 into the infusion stand 46 through one of the one-way valves 43 and the three-head pipe 45. In this way, the reciprocating movement of the piston rod 473 will intermittently push the coolant into the infusion stand 46, and the coolant in the infusion stand 46 will successively pass through the two liquid inlet grooves 322, the liquid through groove 1 321 and the liquid through groove 2 331 into the liquid outlet chamber 332. The coolant in the liquid outlet chamber 332 will be thrown out with the centrifugal force of the saw blade shaft 33 rotating and adhere to the middle position of the circular saw blade 0. Under the inertia of the liquid, the coolant will continue to be thrown in a spiral shape along the surface of the circular saw blade 0 toward the edge, so that the coolant can fully adhere to the surface of the circular saw blade 0, thereby cooling the circular saw blade 0 more efficiently; under the working environment and other factors, the coolant in the cooling box 103 may heat up. Before cutting the edge, the staff can power on the cooling plate 7. When the coolant enters the piston cylinder 41, the cooling plate 7 will cool down the coolant inside the piston cylinder 41, so that the subsequent coolant can cool the circular saw blade 0 more effectively; after the edge cutting is completed, the staff can turn off the motor 31 and cut off the power to the cooling plate 7 at the same time.

[0055] Embodiment 2: Based on embodiment 1, Figure 2-Figure 14As shown, a reinforcing mechanism is also included for increasing the flow rate of the coolant under high strength conditions, and is arranged on the cooling box 103, the one-way valve 42 and the outer frame 101, and the reinforcing mechanism includes: a pipe 2 51 connected to the bottom of the cooling box 103; a transfer pipe 52 installed at the bottom end of the pipe 2 51, a cavity and a lock cavity are formed in the transfer pipe 52, the cavity diameter of the transfer pipe 52 is larger than the lock cavity diameter, and the cavity of the transfer pipe 52 is connected to the pipe 2 51; a hollow groove pipe 53 installed on another one-way valve 42, one end of which is connected to the external air; a U-shaped pipe 54 slidably connected between the transfer pipe 52 and the hollow groove pipe 53; a pull rod 55 installed on the U-shaped pipe 54 and passing through the outer frame 101.

[0056] The top of the U-shaped tube 54 is a side opening structure, and the opening structure of the U-shaped tube 54 is located in the lock cavity of the transfer tube 52 to block the cavity of the transfer tube 52 .

[0057] Initially, one side of the hollow slot tube 53 is connected to the outside air. When the piston rod 473 moves away from the hollow slot tube 53 to push out the coolant, negative pressure is generated on the other side of the piston rod 473, and then the outside air is sucked in through another one-way valve 42 and the hollow slot tube 53. When the automotive parts are larger, harder or thicker, the cutting time and the strength of the circular saw blade 0 are increased, and the circular saw blade 0 may overheat, resulting in poor cooling effect of the intermittent output of coolant on the circular saw blade 0. At this time The staff can pull the pull rod 55 according to the situation, and the pull rod 55 will drive the U-shaped tube 54 to move in the direction close to the piston cylinder 41. During the movement of the U-shaped tube 54, the bottom of the U-shaped tube 54 will extend into the interior of the empty slot tube 53, and then the bottom of the U-shaped tube 54 will be connected with the empty slot tube 53 and block the connection between the empty slot tube 53 and the external air. At the same time, the opening structure of the U-shaped tube 54 will extend into the cavity of the transfer tube 52. Since the cavity diameter of the transfer tube 52 is larger than the diameter of the lock cavity, the top of the U-shaped tube 54 will be The piston rod 473 moves away from the empty slot tube 53 to push out the coolant. The piston rod 473 sequentially passes through another one-way valve 1 42, the empty slot tube 53, the U-shaped tube 54, the transfer tube 52 and the pipeline 2 51 to synchronously absorb the coolant in the cooling box 103 into the piston cylinder 41. When the piston rod 473 moves toward the empty slot tube 53 to absorb the coolant, the piston rod 473 sequentially passes through another one-way valve 2 43 and the three-head tube 45 to absorb the coolant in the piston cylinder 41. The liquid is pushed into the infusion stand 46, so that the head of the piston rod 473 divides the interior of the piston cylinder 41 into two independent chambers. When the piston rod 473 pushes out the coolant in one of the chambers, the coolant will be sucked into the other chamber at the same time, and then the piston rod 473 will continuously and uninterruptedly push the coolant out of the piston cylinder 41 when moving back and forth, so that the coolant continues to adhere to the circular saw blade 0 for cooling, thereby cooling the circular saw blade 0 more quickly, thereby improving the cooling efficiency.

[0058] Embodiment 3: Based on embodiment 2, Figure 2-Figure 17 As shown, a pressurizing mechanism is also included for increasing the coolant flow and strengthening the water pressure at the same time, which is arranged on the saw blade shaft 33 and the pull rod 55, and the pressurizing mechanism includes: two pressurizing blocks 61 slidably connected to the saw blade shaft 33, which are symmetrically arranged on both sides of the liquid groove 331, and are used to control the water pressure by controlling the outlet size of the coolant; the upper and lower ends of the two pressurizing blocks 61 are provided with protrusions 611, a total of four; two limit frames 62 slidably connected to the saw blade shaft 33 are symmetrically arranged, and both sides of the two limit frames 62 are provided with inclined grooves 621, and the two inclined grooves 621 on the same limit frame 62 are symmetrically arranged, and the four protrusions 611 are respectively located in the four inclined grooves 621; a pull ring 63 welded on the pull rod 55 and slidably connected to the outer frame 101, which is used to pull the limit frame 62, and one side of the pull ring 63 contacts with one end of the two limit frames 62 away from each other.

[0059] When the pull rod 55 moves, the pull ring 63 will be driven to move. The movement of the pull ring 63 will pull the two limit frames 62 to move together in the direction close to the transmission shaft 32. The four inclined grooves 621 will respectively squeeze the four protrusions 611 to make the two pressure blocks 61 move towards each other. The movement of the two pressure blocks 61 towards each other will reduce the size of the outlet of the liquid outlet cavity 332. With the effect of the same amount of water and the reduction of the outlet, the water pressure of the cooling water sprayed on the surface of the circular saw blade 0 can be increased, so that the coolant can be more fully attached to the circular saw blade 0, and then the circular saw blade 0 can be cooled more thoroughly, thereby enhancing the cooling effect.

[0060] Although the present disclosure has been described with respect to only a limited number of embodiments, those skilled in the art having benefit of this disclosure will appreciate that various other embodiments can be devised without departing from the scope of the present invention. Accordingly, the scope of the present invention should be limited only by the claims appended hereto.
