Description

Technical Field

[0001] This utility model relates to the field of lifting mechanism technology, and in particular to a synchronous lifting structure for heavy-duty tooling. Background Technology

[0002] In battery box manufacturing, a roller conveyor with accompanying tooling is often used. The weight of the tooling and tray can reach 2-3 tons. At the working position, the tooling needs to be lifted off the roller conveyor to reduce roller wear and achieve precise positioning of the tooling. In the existing technology, the lifting method often uses multiple cylinders or hydraulic cylinders. Due to the inability of the cylinders to be linked and the uneven distribution of the tooling weight, the entire mechanism cannot be precisely controlled synchronously. There will be obvious collisions during lifting, which will also cause great wear to the system. The debugging time for multiple working positions is long and the effect is not ideal.

[0032] Figure 2 This is a schematic diagram of the linkage drive unit of the synchronous lifting structure of the heavy tooling according to an embodiment of the present invention. Detailed Implementation

[0033] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0034] First, combine Figures 1-2 The present invention describes a synchronous lifting structure for heavy tooling according to an embodiment of the present invention, which is used for lifting heavy tooling and has a wide range of applications.

[0035] like Figures 1-2 As shown, the synchronous lifting structure of the heavy-duty tooling of this utility model embodiment includes a base 1, and also includes: a tray 4 and a linkage drive unit, a plurality of vertical guide units 5 and a pair of inclined sliders 2 disposed on the base 1.

[0036] Specifically, such as Figures 1-2 As shown, in this embodiment, a pair of inclined sliders 2 are slidably disposed on the base 1. The inclined surfaces of the pair of inclined sliders 2 are inclined in opposite directions. The inclined sliders 2 are slidably connected to the base 1 via a slide rail 3. The slide rail 3 is fixed on the base 1 and slidably connected to the bottom of the inclined sliders 2. The tray 4 is placed on the pair of inclined sliders 2, and the bottom of the tray 4 abuts against the pair of inclined sliders 2. Multiple vertical guide units 5 are slidably connected to the tray 4. The vertical guide units 5 limit the vertical movement of the tray 4. The number and installation position of the vertical guide units 5 can be adapted to the size and shape of the tray 4, so that the tray 4 can only move in the vertical direction and will not move horizontally with the inclined sliders 2. The linkage drive unit is connected to the pair of inclined sliders 2 and drives the pair of inclined sliders 2 to move closer or further away from each other to drive the tray 4 to move vertically. The linkage drive unit drives the pair of inclined sliders 2 to move synchronously in the horizontal direction. The pair of inclined sliders 2 convert the horizontal force into synchronous lifting of the tray 4 through their inclined surfaces.

[0037] Specifically, such as Figures 1-2As shown, in this embodiment, the tray 4 includes: a tray body 41 and a pair of rolling elements 42; the tray body 41 is used to place tooling, and the pair of rolling elements 42 are disposed at the bottom of the tray body 41 and correspond one-to-one with a pair of inclined sliders 2 respectively. The rolling elements 42 abut against the inclined surfaces of the inclined sliders 2, and the rolling elements 42 may be bearings.

[0038] Specifically, such as Figures 1-2 As shown, in this embodiment, the vertical guide unit 5 includes: a guide rail mounting bracket 51, a guide rail 52, and a connecting block 53; the guide rail mounting bracket 51 is fixed on the base 1; the guide rail 52 is vertically fixed on the guide rail mounting bracket 51; the connecting block 53 is fixed on the tray 4 and slidably connected to the guide rail 52; the guide rail 52 and the connecting block 53 limit the vertical movement of the tray 4.

[0039] Specifically, such as Figures 1-2 As shown, in this embodiment, the linkage drive unit includes: a pair of linkage assemblies and a drive assembly; the pair of linkage assemblies are disposed between a pair of inclined sliders 2, respectively connected to the pair of inclined sliders 2, and both are hinged to the drive assembly; the vertical movement of the drive assembly drives the pair of linkage assemblies to rotate, thereby causing the pair of inclined sliders 2 to move closer to or further away from each other.

[0040] Furthermore, such as Figures 1-2 As shown, in this embodiment, the linkage assembly includes: a slider linkage 61 and a rotating linkage 62; one end of the slider linkage 61 is connected to the inclined slider 2; both ends of the rotating linkage 62 are respectively hinged to the driving assembly and the other end of the slider linkage; the driving assembly drives the rotating linkage 62 to rotate, causing the slider linkage to move horizontally, and the rotating linkage 62 tilts, causing the slider linkage 61 and the inclined slider 2 to move along the slide rail 3.

[0041] Furthermore, such as Figures 1-2 As shown, in this embodiment, the linkage assembly further includes: a linkage guide block 63, which is fixed on the base 1 and sleeved on the slider linkage 61. The slider linkage 61 can slide along the linkage guide block 63, and the linkage guide block 63 guides and limits the movement direction and movement range of the slider linkage 61.

[0042] Furthermore, such as Figures 1-2As shown, in this embodiment, the drive assembly includes: a cylinder 64, a drive shaft 65, and a pair of drive shaft guide blocks 66; the cylinder 64 and the pair of drive shaft guide blocks 66 are fixed on the base 1, the output end of the cylinder 64 is connected to the drive shaft 65, and the drive shaft 65 is hinged to a pair of connecting rod assemblies; the drive shaft guide blocks 66 have guide grooves 67 in the vertical direction, and the two ends of the drive shaft 65 are respectively slidably disposed in the guide grooves 67 of the pair of drive shaft guide blocks 66; the cylinder 64 drives the drive shaft 65 to rise and fall, thereby driving the pair of connecting rod assemblies to rotate, specifically driving one end of the rotating connecting rod 62 to rise and fall. Since the two ends of the rotating connecting rod 62 are respectively hinged to the drive shaft 65 and the slider connecting rod 61, the rotating connecting rod 62 will rotate and tilt, causing the slider connecting rod 61 to move horizontally under the limitation of the connecting rod guide block 63. In this embodiment, the output end of the cylinder 64 is connected to the drive shaft 65 through an elbow joint 68.

[0043] Furthermore, such as Figures 1-2 As shown, in this embodiment, the two ends of the inclined slider 2 extend vertically upward to form a limiting plate 21, which limits the sliding range of the inclined slider 2.

[0044] In this embodiment, the number of inclined sliders 2 can be set to multiple according to the size of the tray 4, but they must be set in pairs to ensure stability. For example, two pairs or three pairs can be set. The number of rolling elements 42 is set according to the number of inclined sliders 2. One rolling element 42 abuts against one inclined slider 2, and one inclined slider 2 is connected to one linkage assembly. Each linkage assembly is hinged to the drive shaft 65. At this time, multiple inclined sliders 2 can be synchronously driven under the drive of one cylinder 64.

[0045] like Figures 1-2 As shown, taking two pairs of inclined sliders 2 as an example, the tray 4 is connected to the entire base 1 through four vertical guide units 5 and can move up and down along the guide rail 52; bearings are installed at the four corners below the tray 4 and contact the inclined surfaces of the four inclined sliders 2, allowing the inclined sliders 2 to move back and forth in the horizontal direction; the slider connecting rod 61 passes through the connecting rod guide block 63 and is connected to the inclined slider 2 and the rotating connecting rod 62 respectively through pins; the transmission shaft 65 is installed in a pair of transmission shaft guide blocks 66 and can move up and down and connect the four rotating connecting rods 62; the cylinder 64 is connected to the transmission shaft 65 through the toggle joint 68. When tray 4 needs to be lowered, cylinder 64 extends, driving drive shaft 65 to move upward in guide groove 67 of drive shaft guide block 66. Rotating connecting rod 62, under the action of drive shaft guide block 66 and connecting rod guide block 63, makes an inclined movement with one end upward and the other end close to drive shaft 65. Then, slider connecting rod 61 drives inclined slider 2 to move horizontally towards the side close to drive shaft 65. The bearing at the bottom of tray 4 moves relative to the inclined surface of inclined slider 2. At this time, tray 4 descends along guide rail 52. When cylinder 64 reaches its stroke, the four sets of inclined sliders 2 reach the position close to drive shaft 65 simultaneously, and the work is completed.

[0046] When tray 4 needs to rise, cylinder 64 retracts, driving drive shaft 65 to move downward in guide groove 67 of drive shaft guide block 66. Rotating connecting rod 62, under the action of drive shaft guide block 66 and connecting rod guide block 63, makes an inclined movement with one end downward and the other end horizontal away from drive shaft 65. Then, slider connecting rod 61 drives inclined slider 2 to move horizontally away from drive shaft 65. The bearing at the bottom of tray 4 moves relative to the inclined surface of inclined slider 2. At this time, tray 4 rises along guide rail 52. When cylinder 64 reaches its stroke, the four sets of inclined sliders 2 simultaneously reach the position away from drive shaft 65, and the work is completed.

[0047] This structure can also change the tilt direction of the inclined plane of the inclined slider 2, so as to achieve the effect of the cylinder 64 extending and retracting, and the tray 4 descending and rising synchronously. The process is the same as above.

[0048] Above, refer to Figures 1-2 This invention describes a synchronous lifting structure for heavy-duty tooling according to an embodiment of the present invention. It employs inclined sliders to convert the vertical lifting force into a horizontal force, and uses the movement of angled sliders to achieve the lifting effect. It can lift heavy tooling with a smaller cylinder. In conjunction with connecting rods, guides, and drive shafts, the vertical movement of one or a group of cylinders is transformed into synchronous horizontal drive of multiple sets of inclined sliders, achieving synchronous lifting. Even if the weight of the tooling is uneven, the entire system can still operate smoothly.
