Description

Technical Field

[0001] This utility model relates to the field of battery cooling flat tube cutting technology, specifically to a flat tube cutting tool. Background Technology

[0002] Battery cooling flat tubes are devices used for heat dissipation in batteries. Battery packs generate a significant amount of heat during operation; if this heat cannot be dissipated in time, it will affect battery life and performance. Cooling flat tubes utilize a circulating cooling fluid (such as water or refrigerant) to carry away the heat generated by the battery and dissipate it to the external environment, thereby maintaining a stable internal temperature of the battery pack. The use of cooling flat tubes is of great significance for improving battery efficiency, extending lifespan, and ensuring battery pack safety.

[0003] Flat tubes are typically cut manually or automatically. Automated cutting equipment is more efficient, but also more expensive. Manual cutting usually involves the use of cutting equipment and fixtures.

[0004] For example, Chinese patent document CN111644686B discloses a device for manually and quickly cutting flat tubes. This device includes a handle, a cutting mechanism connected to the handle, and an adjustment mechanism connected to the bottom of the cutting mechanism. The cutting mechanism includes a housing, an operating groove on the housing, a drive handle within the operating groove, a cutting groove at the bottom of the housing, a cutting blade within the cutting groove, and a drive mechanism between the drive handle and the cutting blade. The drive mechanism includes a limiting connecting plate connected to the drive handle, several springs connected to the upper end of the limiting connecting plate, a drive rod connected to the lower end of the limiting connecting plate, an inner hole at the lower end of the drive rod, and a screw within the inner hole. This device for manually and quickly cutting flat tubes can be applied to the cutting process of flat tubes in prototype and mass production, solving the problem of lacking tooling for prototype production and switching between multiple product varieties, improving production efficiency, and is versatile, easy to operate, and reduces the cost of tooling manufacturing.

[0005] However, the above-mentioned device also has certain drawbacks: the manual cutting device can only perform two flat tube cutting operations at the same time during use, resulting in low work efficiency; in addition, the device relies on the cutting groove to complete the radial direction calibration of the flat tube, and the thickness of the cutting groove is small, which makes the cutting accuracy of the flat tube low. When cutting manually, defects such as skewed cuts are easily caused, affecting the cutting quality of the flat tube. Utility Model Content

[0006] This utility model provides a flat tube cutting fixture to solve the technical problem of low cutting accuracy and efficiency of existing manual flat tube cutting devices.

[0013] When the crank rotates upward, the lower pressure plate moves upward and releases the flat tube; when the crank rotates downward, the lower pressure plate moves downward and presses the flat tube into a pressing state.

[0014] Furthermore, both of the lower pressure rods are screwed to the bottom with adjusting screws that extend vertically. The upper side of the lower pressure plate is provided with a fixing block, which has a U-shaped groove. The lower side of the U-shaped groove has a retaining groove, which is used to press the lower end of the adjusting screw to fix the lower pressure plate and the adjusting screw.

[0015] Furthermore, two left-right extending guide rods are provided on the placement plate and on the left side of the placement slot, and the side top plate is fixed to the right end of the two guide rods;

[0016] The left end of the placement plate is also screwed with a screw extending to the left and right. The left end of the screw is fixed with a locking knob, and the right end of the screw has a circumferentially extending annular groove. The left side of the side top plate is fixed with a connecting block, which has a stepped groove that mates with the annular groove, so that the side top plate moves left and right with the screw.

[0017] Furthermore, a handle is provided at the left end of the placement plate to facilitate the operator to apply force to push the placement plate.

[0018] Furthermore, the drive motor is a speed-regulating motor, which is fixed on the operating platform. The front end of the drive motor is the output end, and a transmission wheel is provided at its front end. A support frame is provided on the operating platform and in front of the drive motor.

[0035] The principles and spirit of this utility model will be explained in detail below with reference to several representative embodiments.

[0036] Embodiment 1 of the flat tube cutting fixture provided by this utility model:

[0037] like Figures 1 to 5 As shown, the fixture includes an operating platform 1, on which a fixed plate 2 is fixedly mounted. Two parallel slide rails 3 are mounted on the fixed plate 2, extending horizontally. Limiting blocks 31 are provided at both ends of the two slide rails 3. A clamping assembly 4 is slidably mounted on the two slide rails 3, used to fix the flat tube. A cutting assembly 5 is located on the operating platform 1 and behind the fixed plate 2, used to cut the flat tube.

[0038] The clamping component 4 will be introduced first below, such as Figure 1 and Figure 2As shown, the clamping assembly 4 includes a placement plate 41 slidably mounted on two slide rails 3, with two sliders provided between the placement plate 41 and each of the two slide rails 3. The placement plate 41 has a rectangular placement groove 411 extending front to back, which is used to place the flat tube. On the placement plate 41 and located to the right of the placement groove 411, there are two vertically extending support plates 42. The support plates 42 are L-shaped plates, and their lower ends are fixedly connected to the placement plate 41. The upper left side of each of the two support plates 42 is provided with a mounting plate 43.

[0039] like Figure 1 and Figure 2 As shown, each mounting plate 43 and its corresponding support plate 42 are connected by bolts, and a gasket 421 is provided between the mounting plate 43 and the corresponding support plate 42 to prevent the bolts between the mounting plate 43 and the support plate 42 from loosening. A hinge arm 431 extending obliquely upwards and to the left is provided on the left side of the mounting plate 43. A crank 44 bent downwards is provided on the lower side of the hinge arm 431, and the crank 44 has a long end and a short end. The right end of the short end is hinged to the left end of the hinge arm 431, and the left end of the long end has a handle 441 for easy gripping.

[0040] like Figure 1 and Figure 2 As shown, each mounting plate 43 also has a guide arm 432 extending downward to the left on its left side. The left end of the guide arm 432 has a guide sleeve 433 extending vertically. A cylindrical pressure rod 46 is slidably mounted inside the guide sleeve 433. There are two connecting plates 45 between the top of the pressure rod 46 and the bent part of the crank 44. The two connecting plates 45 are located on the front and rear sides of the pressure rod 46 and the crank 44, respectively, and the upper and lower ends of the two connecting plates 45 are respectively hinged to the bent part of the crank 44 and the top of the pressure rod 46. Each pressure rod 46 has a pressure plate 48 fixed at its lower end. The pressure plate 48 is a horizontally arranged rectangular plate. When the long end of the crank 44 rotates upward, the pressure rod 46 moves upward under the drive of the connecting plate 45. At this time, the pressure plate 48 is in a released state where it moves upward and releases the flat tube. When the long end of the crank 44 rotates downward, the pressure rod 46 moves downward under the push of the connecting plate 45. At this time, the pressure plate 48 is in a pressed state where it moves downward and presses the flat tube.

[0041] like Figure 2 and Figure 4As shown, each pressure rod 46 has an adjusting screw 461 screwed to its bottom. The adjusting screw 461 extends vertically with its head facing downwards, and a nut 462 is fitted onto the adjusting screw 461. The nut 462 is used to adjust the extension length of the adjusting screw 461 at the bottom of the pressure rod 46. Each pressure plate 48 has a fixing block 47 on its upper side, and the fixing block 47 is fixedly connected to the pressure plate 48 by screws. The fixing block 47 has a through U-shaped groove 471 for the adjusting screw 461 to pass through. The lower side of the U-shaped groove 471 has an outwardly expanding slot 472 for pressing the head of the adjusting screw 461 downwards to fix the pressure plate 48 and the pressure rod 46 together.

[0042] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, two left-right extending guide rods 491 are inserted through the left end of the placement plate 41, located to the left of the placement groove 411. A front-rear extending side top plate 49 is fixed to the right end of the two guide rods 491. A left-right extending screw 492 is also screwed to the left end of the placement plate 41, located between the two guide rods 491. The left end of the screw 492 has a locking knob 493 for easy rotation. The right end of the screw 492 has a circumferentially extending annular groove 497. A rectangular connecting block 494 is fixed to the left side of the side top plate 49. The connecting block 494 has a stepped groove 495 that expands from left to right. The stepped groove 495 is used to engage with the annular groove 497, allowing the side top plate 49 to move left and right with the screw 492. A handle 496 is also provided at the left end of the placement plate 41 to facilitate the operator's application of force to push the placement plate 41.

[0043] Then, we will introduce cutting component 5, such as... Figure 1 and Figure 3 As shown, the cutting assembly 5 includes a drive motor 51 located behind the fixed plate 2. The drive motor 51 is fixed to the operating platform 1 and is a speed-regulating motor. The front end of the drive motor 51 is the output end, and it has a transmission wheel 52. A support frame 54 is located on the front side of the drive motor 51. The right end of the support frame 54 is fixed to the operating platform 1, and the left end of the support frame 54 is a cantilever structure to facilitate the passage of the flat tube to be cut. A transmission shaft 55 extending forward and backward is passed through the left end of the support frame 54. A transmission wheel 56 is sleeved at the rear end of the transmission shaft 55. A synchronous belt 53 is sleeved on the transmission wheel 52 and the transmission wheel 56. A rotating blade 57 is fixed to the front end of the transmission shaft 55 to drive the rotating blade 57 to rotate via the synchronous belt 53. The rotating blade 57 is a polygonal blade to improve the cutting quality of the cut surface.

[0044] In addition, a controller 6 is provided on the front side of the drive motor 51. The controller 6 is used to adjust the speed of the drive motor 51 according to the size and material of different flat tubes in order to improve the cutting efficiency of the flat tubes.

[0045] The application principle of this tooling is as follows: First, multiple flat tubes to be cut are stacked in the placement groove 411. Then, the locking knob 493 is rotated to move the side top plate 49 to the right and press the flat tubes to the right. Then, the two handles 441 are rotated downward to press the flat tubes downward with the lower pressure plate 48. At this time, the flat tubes are fixed in the placement groove 411 under the action of the lower pressure plate 48 and the side top plate 49. Then, the drive motor 51 is started by the controller 6. After adjusting the speed of the drive motor 51, the clamping component 4 is pushed to the right by the handle 496. At this time, each flat tube is cut under the action of the rotating blade 57.

[0046] The flat tube is fixed in the placement groove 411 by the pushing action of the side top plate 49 and the lower pressure plate 48, which can prevent the flat tube from being placed crookedly. At the same time, the adjustable side top plate 49 makes the tooling compatible with flat tubes of different widths, improving the applicability of the cutting tooling. In addition, the placement plate 41 moves to the right under the guidance of the two slide rails 3, ensuring the straightness of the flat tube cut.

[0047] Embodiment 2 of the flat tube cutting fixture provided by this utility model:

[0048] Its main difference from Example 1 is:

[0049] In Example 1, the rotating blade and the drive motor are connected by a synchronous belt drive.

[0050] In this embodiment, the rotating blade and the drive motor are connected by gear transmission.

[0051] Embodiment 3 of the flat tube cutting fixture provided by this utility model:

[0052] Its main difference from Example 1 is:

[0053] In Example 1, the placement plate is moved left and right along the slide rail by manually applying force.
