DETAILED DESCRIPTION

[0022] The following describes in detail embodiments of the present invention. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended only to explain the present invention and are not to be construed as limiting the present invention.

[0023] In the description of the present invention, it should be understood that descriptions involving orientations, such as up, down, front, back, left, right, etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present invention.

[0024] In the description of this utility model, "a plurality" means more than two. The use of "first" or "second" is solely for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of technical features indicated, or implicitly indicating the order of the technical features indicated.

[0025] In the description of the present invention, unless otherwise clearly defined, terms such as setting, installing, and connecting should be understood in a broad sense, and technicians in the relevant technical field can reasonably determine the specific meanings of the above terms in the present invention based on the specific content of the technical solution.

[0026] Reference Figure 1 and Figure 2 The utility model discloses a leveling tool, including a base 100 and a lifting and fine-tuning mechanism 200 and a quick clamp 400 both arranged on the base 100. The quick clamp 400 presses the product against the lifting and fine-tuning mechanism 200, and the quick clamp 400 and the lifting and fine-tuning mechanism 200 clamp and realize the function of flattening the product.

[0027] The lifting and fine-tuning mechanism 200 is provided with a supporting platform 300, and the supporting platform 300 is provided with a positioning groove 310 for positioning the product; the quick clamp 400 includes a mounting plate 410, a pressure rod 420 which can slide up and down on the mounting plate 410, and a handle 430 with one end hinged to the mounting plate 410, the mounting plate 410 is connected to the base 100, the middle part of the handle 430 is hinged to the upper end of the pressure rod 420 through the connecting plate 440, and the lower end of the pressure rod 420 is connected to the pressing assembly 500 above the positioning groove 310. By rotating the handle 430, the handle 430 can drive the pressure rod 420 to descend, that is, drive the pressing assembly 500 to rise and fall.

[0028] When the flatness of the product needs to be processed, the pressure rod 420 is first driven to a high position through the handle 430, so that the pressing component 500 is away from the object platform 300, and then the product is positioned in the positioning groove 310 of the object platform 300. Then, the pressure rod 420 is driven to a lower position through the handle 430, so that the pressing component 500 presses the product tightly down in the positioning groove 310 of the object platform 300. The pressing component 500 and the object platform 300 are in a state of clamping the product, thereby flattening the product and obtaining a finished product with qualified flatness.

[0029] Because the pressing assembly 500 and the support platform 300 are in a state of clamping the product, the distance between the pressing assembly 500 and the support platform 300 when the pressing assembly 500 is in its lowest position determines the force with which the flattening tool flattens the product. The greater the distance between the pressing assembly 500 and the support platform 300, the greater the force with which the flattening tool flattens the product. By adjusting the height of the support platform 300 through the lifting and fine-tuning mechanism 200, the distance between the pressing assembly 500 and the support platform 300 is adjusted, and thus the force with which the product is flattened is adjusted, ensuring that the overall flatness of the product is improved without damaging its appearance.

[0030] It should be noted that since the product itself has concave and convex structures, the lower surface of the pressing component 500 and the bottom of the positioning groove 310 should be compatible with the product to avoid the inherent concave and convex structure of the product being deformed when the pressing component 500 and the support platform 300 clamp the product.

[0031] The leveling tool replaces manual straightening of products, which can effectively improve the flatness of the products, thereby improving the product qualification rate, reducing the production cost of the products, and reducing the workload of personnel and labor costs.

[0032] It can be understood that a first guide sleeve is provided on the mounting plate 410 , the central axis of the first guide sleeve is in the up-down direction, and the pressure rod 420 is passed through the through hole of the first guide sleeve.

[0033] In some embodiments, the base 100 includes a bottom plate 130, a guide plate 110, and a side plate 120. The bottom plate 130 is located below the guide plate 110. The bottom plate 130 and the guide plate 110 are connected by at least three support columns. The side plate 120 can be connected to one of the bottom plate 130 and the guide plate 110, or both the bottom plate 130 and the guide plate 110 are connected to the side plate 120. The bottom plate 130 and the guide plate 110 are arranged horizontally, while the side plate 120 is arranged vertically. The side plate 120 is located above the guide plate 110 and connected to the mounting plate 410. The side plate 120 supports the entire quick clamp 400.

[0034] In some embodiments, the guide plate 110 is provided with a guide hole 111 for the platform 300 to slide up and down. Under the action of the guide hole 111, the platform 300 moves in the up and down direction, so the guide hole 111 serves to limit the moving direction of the platform 300.

[0035] The lifting and fine-tuning mechanism 200 is disposed on the bottom plate 130 and is located just below the guide hole 111 . The output end of the lifting and fine-tuning mechanism 200 can be directly connected to the object support platform 300 .

[0036] In some embodiments, the lifting fine-tuning mechanism 200 is a worm elevator, wherein the worm (output end) of the worm elevator is arranged upward and connected to the object support platform 300. The worm elevator is a common component.

[0037] It is conceivable that the worm elevator includes a base and a turbine and worm both mounted on the base. The turbine and worm mesh with each other, with the worm being vertically disposed and threadedly connected to the base. The upper end of the worm extends above the base and is rotatably connected to the object support platform 300. The turbine is connected to a drive shaft that extends outside the base. The drive shaft drives the turbine to rotate, which in turn drives the worm to rotate, thereby driving the worm to lift.

[0038] In this embodiment, the worm gear elevator is connected to the base plate 130 .

[0039] See also Figure 3 and Figure 4 In some embodiments, the leveling tool further includes a timing device 600, which includes a swingable lever 610. The lever 610 can be positioned above the handle 430 to prevent the pressure rod 420 / pressing assembly 500 from rising.

[0040] It can be imagined that the operation of the pressing component 500 and the support platform 300 clamping the product is the pressure-holding step, and the length of time the pressing component 500 and the support platform 300 clamp the product is the pressure-holding time. The leveling of the product requires a certain pressure-holding time. When the pressing component 500 is pressed on the product, the gear lever 610 can swing (swing forward) to the top of the handle 430 to limit the pressure rod 420 and the pressing component 500, thereby completing the pressure-holding step of the product. When the pressing component 500 presses the product down for a set time, that is, after the pressure is completed, the gear lever 610 swings in the opposite direction to leave the top of the handle 430, so that the pressure rod 420 / pressing component 500 can move upward.

[0041] The timing device 600 can drive the gear lever 610 to swing at a fixed time, thereby indicating when the personnel should operate the handle 430 to drive the pressure rod 420 / pressure assembly 500 to rise, which can prevent the personnel from operating the leveling tooling without following the pressure holding time, ensuring that the product pressure holding requirements meet the set conditions, and thus ensuring the product leveling effect and quality.

[0042] In some embodiments, the timing device 600 also includes a shell 620 and a timing control circuit board and a rotation drive mechanism both of which are arranged in the shell 620. The shell 620 is detachably connected to the base 100, the timing control circuit board and the rotation drive mechanism are electrically connected, the timing control circuit board controls the forward and reverse rotation of the rotation drive mechanism, the output end of the rotation drive mechanism is connected to the gear lever 610, and the rotation drive mechanism drives the gear lever 610 to swing.

[0043] It is understood that the timing control circuit board is provided with an interval time for controlling the forward and reverse rotation of the rotary drive mechanism, which is the pressure holding time. The timing control circuit board controls the operation of the rotary drive mechanism, which drives the gear lever 610 to swing forward, so that the gear lever 610 is blocked above the handle 430. After the pressure holding time, the timing control circuit board automatically controls the operation of the rotary drive mechanism again, which drives the gear lever 610 to swing backward, so that the gear lever 610 is removed from the top of the handle 430. This notifies the personnel that the product pressure holding is complete. The personnel can lift the handle 430, thereby moving the pressure rod 420 and the pressure assembly 500 upward, and then remove the leveled product from the positioning groove 310.

[0044] The rotation drive mechanism is a motor, which is horizontally arranged. The surface where the handle 430 rotates is parallel to the output shaft of the motor, and the gear lever 610 is perpendicular to the output shaft of the motor.

[0045] In this embodiment, the handle 430 is located above the pressure rod 420 / pressure assembly 500, and the area of the handle 430 near one end of the handle 430 is provided with a gear position. The gear rod 610 can swing from top to bottom to above the gear position and very close to the gear position. The gear rod 610 limits the rise of the handle 430 to achieve the limit of the rise of the pressure rod 420 / pressure assembly 500.

[0046] Of course, a stopper may be provided on any one of the handle 430 , the pressure rod 420 and the pressing assembly 500 , and the stopper rod 610 may be swung to the top of the stopper, thereby limiting the rise of the handle 430 , the pressure rod 420 and the pressing assembly 500 .

[0047] In some embodiments, a minute-second setting knob 630 and a running button 640 are provided on the housing 620. Both the minute-second setting knob 630 and the running button 640 are electrically connected to a timing control circuit board. The minute-second setting knob 630 inputs an interval time instruction to the timing control circuit board, and the minute-second setting knob 630 sets the duration of one forward and reverse rotation cycle of the rotary drive mechanism, that is, sets the pressure holding time. The running button 640 inputs an interval action instruction to the timing control circuit board. Pressing the running button 640 once causes the timing control circuit board to control the rotary drive mechanism to rotate forward or reverse once, thereby starting or urgently stopping pressure holding.

[0048] In this embodiment, a battery compartment 650 is further provided on the housing 620. The battery compartment 650 is used to place an external power supply. The external power supply is electrically connected to the timing control circuit board to supply power to the timing control circuit board.

[0049] In some embodiments, the housing 620 is further provided with an in-position sensor 660, which is electrically connected to the timing control circuit board. The in-position sensor 660 is opposite to the area when any one of the handle 430, the pressure rod 420 and the pressing assembly 500 is in the lower position. When the handle 430, the pressure rod 420 and the pressing assembly 500 are in the lower position, that is, when the pressing assembly 500 starts to press the product, any one of the handle 430, the pressure rod 420 and the pressing assembly 500 triggers the in-position sensor 660, and the in-position sensor 660 sends a start signal to the timing control circuit board. After receiving the start signal, the timing control circuit board enters the pressure maintaining operation, and the timing control circuit board controls the operation of the rotation drive mechanism, and the rotation drive mechanism drives the gear lever 610 to swing forward.

[0050] In some embodiments, the pressing assembly 500 includes a pressing block 510 connected to the lower end of the pressing rod 420 and an elastic pad 520 provided on the lower surface of the pressing block 510. The elastic pad 520 is elastic and can prevent the product from being crushed. The elastic pad 520 is a high-strength rubber stick.

[0051] It is conceivable that the bottom of the positioning groove 310 can be made of a high-strength rubber stick.

[0052] In some embodiments, the pressing block 510 is connected to the base 100 in a liftable manner via a guide rod 700 . The guide rod 700 serves to guide the movement of the pressing block 510 , so that the pressing block 510 can be lifted and lowered smoothly.

[0053] Specifically, there are two guide rods 700, which are flush with each other. Second guide sleeves are provided at both ends of the pressure block 510, and the central axis of the second guide sleeves is in the up and down direction. The two guide rods 700 are respectively passed through the through holes of the two second guide sleeves.

[0054] Specifically, the pressing block 510 is connected to the side plate 120 in a liftable manner via the guide rod 700 .

[0055] The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0056] Of course, the present invention is not limited to the above-mentioned embodiments. Those skilled in the art may make equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
