Description

Technical Field

[0001] This utility model belongs to the field of fine-tuning platform technology and relates to a mold fine-tuning tooling. Background Technology

[0002] In the production process of lithium batteries, molds are used extremely frequently and require very strict precision. Typically, each mold needs to be repaired and maintained after about one million uses to ensure product consistency and pass rate. Due to processing errors of the equipment itself, mold installation errors, and structural deformation caused by long-term operation, each time a new mold is replaced or a repaired mold is completed, fine-tuning and calibration are required in three directions: the X-axis, Y-axis, and θ-axis (the direction of rotation around the Z-axis).

[0003] However, due to the compact structure and high safety requirements of lithium battery production equipment, the internal operating space is extremely limited, making it impossible for maintenance personnel to enter the equipment for direct adjustments. They can only operate the equipment by lying on the outside with their arms outstretched. This adjustment method is not only inefficient but also easily leads to physical fatigue and occupational injuries. Utility Model Content

[0024] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0025] 1. This tooling can achieve fine adjustment of the mold in three directions. During the adjustment process, the mold fixing plate can be translated in X / Y on the base plate, while the entire base plate (together with the mold fixing plate) can be rotated in θ. This overcomes the drawback that equipment maintenance personnel need to enter the equipment to make adjustments, reduces the adjustment difficulty and workload of operators, and improves work efficiency.

[0026] 2. By using a hex wrench to turn the corresponding adjusting screws in sequence, fine adjustments in the X, Y, and θ directions can be achieved respectively.

The structural design is simple and intuitive, which greatly simplifies the debugging process, improves operating efficiency, and facilitates daily equipment maintenance and quick mold changes.

[0027] 3. When the mold fixing plate slides along the X direction, the first elastic reset member is compressed and deformed. At this time, the second elastic reset member slides on the second limit plate through the bullseye bearing to ensure that there is no motion interference between the two. Similarly, when the mold fixing plate slides along the Y direction, the first elastic reset member slides on the first limit plate through the bullseye bearing to ensure that there is no motion interference between the two.

Detailed Implementation

[0034] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0035] like Figures 1 to 5 As shown, a mold fine-tuning fixture includes:

[0036] The substrate 100 is configured to be able to rotate in the θ direction about the Z-axis as the rotation center.

[0037] Mold fixing plate 200 is movably disposed on substrate 100 and fixed to substrate 100 in the θ direction. One side of one opposite side of mold fixing plate 200 is configured as a first inclined surface 210 and the other side is configured as a first force-bearing part 220. One side of the other opposite side of mold fixing plate 200 is configured as a second inclined surface 230 and the other side is configured as a second force-bearing part 240.

[0038] The X-axis fine-tuning mechanism includes a first wedge block 300 and a first elastic reset member 400. The first wedge block 300 is vertically connected to the base plate 100. The first wedge block 300 is in contact with the first inclined surface 210 and forms a wedge mechanism that can drive the mold fixing plate 200 to move in the X direction. The two ends of the first elastic reset member 400 are respectively connected to the base plate 100 and the first force receiving part 220.

[0039] The Y-axis fine-tuning mechanism includes a second wedge block 500 and a second elastic reset member 600. The second wedge block 500 is vertically connected to the base plate 100. The second wedge block 500 is in contact with the second inclined surface 230 and forms a wedge mechanism that can drive the mold fixing plate 200 to move in the Y direction. The two ends of the second elastic reset member 600 are respectively connected to the base plate 100 and the second force receiving part 240.

[0040] The θ-axis fine-tuning mechanism includes an eccentric cam 700, which is in contact with the substrate 100. The angular position of the eccentric cam 700 determines the θ-axis position of the substrate 100 and the mold fixing plate 200.

[0041] This fixture is positioned between the equipment and the mold, enabling fine-tuning of the mold in three directions: X, Y, and θ. The X direction is defined as the direction along the X-axis, the Y direction as the direction along the Y-axis, and the θ direction as the direction of rotation around the Z-axis.

[0042] The base plate 100 is the foundation for the installation and θ-axis rotation of the entire tooling, and is used for fixed connection with the equipment or workbench; the mold fixing plate 200 is used for fixed connection with the mold, and the mold fixing plate 200 can move along the X or Y direction on the base plate 100; the X-axis fine adjustment mechanism and the Y-axis fine adjustment mechanism have the same structure and working principle, both of which use the wedge principle to convert the vertical displacement (along the Z-axis direction) into horizontal displacement (X or Y direction).

[0043] The working principle of the θ-direction fine adjustment mechanism is to use the rotation of the eccentric cam 700 to drive the base plate 100 to rotate relative to the equipment, thereby changing the θ-direction angle of the mold fixing plate 200.

[0044] The mold fixing plate 200 is preferably rectangular in structure. The first inclined surface 210 and the first force-bearing part 220 are located on opposite sides of the mold fixing plate 200, and the second inclined surface 230 and the second force-bearing part 240 are located on the other opposite sides of the mold fixing plate 200. One of the opposite sides of the mold fixing plate 200 is connected to the inclined wedge and the other is held against by the elastic reset member, so that the mold fixing plate 200 can move bidirectionally in the X direction or the Y direction.

[0045] Specifically, the wedge block can move up and down in the Z direction. When the wedge block descends, the mold fixing plate 200 is squeezed by the wedge block, thus generating displacement. At this time, the elastic reset member opposite the wedge block deforms and stores force. When the wedge block rises, the elastic reset member pushes the mold fixing plate 200 to move in the opposite direction. This design controls the displacement of the mold fixing plate 200 through the cooperation of the wedge mechanism and the elastic reset member. That is, by controlling the height position of the wedge block in the Z direction, the displacement of the mold fixing plate 200 in the X or Y direction can be controlled.

[0046] Taking the X-axis fine-tuning process as an example: when the first wedge block 300 descends, it forces the mold fixing plate 200 to move forward in the X direction; when the first wedge block 300 rises, the mold fixing plate 200 retracts in the X direction under the action of the first elastic reset member 400. Thus, the displacement of the mold fixing plate 200 in the X direction is controlled by the height of the first wedge block 300. The Y-axis fine-tuning process is the same as the X-axis fine-tuning process, and will not be described again here.

[0047] The substrate 100 is hinged to the equipment or worktable via a hinge shaft 140. The eccentric cam 700 is rotatably connected to the equipment via a third adjusting screw 710. The edge of the eccentric cam 700 abuts against the substrate 100, so the substrate 100 remains fixed to the equipment when the eccentric cam 700 is not rotating. When the eccentric cam 700 rotates, it can push the substrate 100 to rotate around its hinge shaft 140 (which can be regarded as the Z-axis), thereby changing the θ-direction angle of the mold fixing plate 200 on the substrate 100.

[0048] In simple terms, the principle of the θ-direction rotation of the mold fixing plate 200 is as follows: Since the mold fixing plate 200 and the base plate 100 are locked in the θ direction, the mold fixing plate 200 rotates together with the base plate 100 when the base plate 100 rotates around the Z-axis. The eccentric cam 700 is linked with the base plate 100 through the eccentric structure, so the eccentric cam 700 can push the base plate 100 to rotate around the hinge axis 140 as the rotation center, thereby realizing the θ-direction angle adjustment.

[0049] This tooling can achieve fine adjustment of the mold in three directions. During the adjustment process, the mold fixing plate 200 can be translated in X / Y on the base plate 100, while the entire base plate 100 (together with the mold fixing plate 200) can be rotated in θ. This overcomes the drawback that equipment maintenance personnel need to enter the equipment to make adjustments, reduces the adjustment difficulty and workload of operators, and improves work efficiency.

[0050] like Figures 1 to 4As shown, based on the above embodiment, the first wedge block 300 is provided with a first adjusting screw 310, which is threadedly connected to the base plate 100. The first adjusting screw 310 is configured to control the X-axis travel position of the mold fixing plate 200 by adjusting the lifting height of the first wedge block 300; the second wedge block 500 is provided with a second adjusting screw 510, which is threadedly connected to the base plate 100. The second adjusting screw 510 is configured to control the Y-axis travel position of the mold fixing plate 200 by adjusting the lifting height of the second wedge block 500; the rotation center of the eccentric cam 700 is provided with a third adjusting screw 710, which is circumferentially fixedly connected to the eccentric cam 700. The third adjusting screw 710 is configured to control the rotation angle of the base plate 100 and the mold fixing plate 200 through the eccentric cam 700.

[0051] Since both the first adjusting screw 310 and the second adjusting screw 510 are screwed to the base plate 100, the Z-axis height of the first wedge block 300 or the second wedge block 500 can be adjusted by turning the first adjusting screw 310 or the second adjusting screw 510.

[0052] The substrate 100 can rotate around the hinge axis 140 (Z-axis) to achieve θ-axis angle adjustment. The eccentric cam 700 is in contact with the substrate 100. When the eccentric cam 700 rotates, it can push the substrate 100 to rotate around the hinge axis 140. The third adjusting screw 710 is set as the rotation center of the eccentric cam 700. The third adjusting screw 710 is threadedly connected to the equipment or workbench. By turning the third adjusting screw 710, the eccentric cam 700 can be rotated, thereby pushing the substrate 100 and the mold fixing plate 200 on it to rotate together around the Z-axis, changing the θ-axis angle between the substrate 100 and the mold fixing plate 200.

[0053] Preferably, the first adjusting screw 310, the second adjusting screw 510, and the third adjusting screw 710 are all configured as internal hexagon or external hexagon screws.

[0054] By using a hex wrench to turn the corresponding adjusting screws in sequence, fine adjustments in the X, Y, and θ directions can be achieved respectively. Each direction adjustment only requires operating one screw. The structural design is simple and intuitive, which greatly simplifies the debugging process, improves operating efficiency, and facilitates daily equipment maintenance and quick mold changes.

[0055] Based on the above embodiments, the substrate 100 is provided with a first guide rod 320 and a second guide rod 520. The first guide rod 320 passes through the first wedge block 300 and the first wedge block 300 is slidably connected to the first guide rod 320. The second guide rod 520 passes through the second wedge block 500 and the second wedge block 500 is slidably connected to the second guide block.

[0056] The guide rod forces the wedge block to move only along the Z-axis, thus providing guidance and ensuring a smooth and unobstructed lifting process.

[0057] like Figures 1 to 3 As shown, based on the above embodiment, the substrate 100 is provided with a first limiting plate 110 and a second limiting plate 120, the first limiting plate 110 being close to the first force-bearing part 220, and the second limiting plate 120 being close to the second force-bearing part 240.

[0058] One end of the first elastic reset member 400 is provided with a first bullseye bearing 410. One end of the first elastic reset member 400 is slidably connected to one of the first limiting plate 110 and the first force receiving part 220 through the first bullseye bearing 410. The other end of the first elastic reset member 400 is fixedly connected to the other of the first limiting plate 110 and the first force receiving part 220.

[0059] One end of the second elastic reset member 600 is provided with a second bullseye bearing 610. One end of the second elastic reset member 600 is slidably connected to one of the second limiting plate 120 and the second force-receiving part 240 through the second bullseye bearing 610. The other end of the second elastic reset member 600 is fixedly connected to the other of the second limiting plate 120 and the second force-receiving part 240.

[0060] Bullseye bearings are used to ensure that the elastic reset member can slide relative to the force-bearing part or the limiting plate. The two ends of the elastic reset member are not directly fixedly connected to the limiting plate and the force-bearing part. One end is slidably connected to one of the limiting plate and the force-bearing part through the bullseye bearing, and the other end is fixedly connected to the other of the limiting plate and the force-bearing part, so that the elastic reset member will not bend due to the movement of the mold fixing plate 200.

[0061] For example, when the mold fixing plate 200 slides along the X direction, the first elastic reset member 400 is compressed and deformed. At this time, the second elastic reset member 600 slides on the second limit plate 120 through the bullseye bearing to ensure that there is no motion interference between the two. Similarly, when the mold fixing plate 200 slides along the Y direction, the first elastic reset member 400 slides on the first limit plate 110 through the bullseye bearing to ensure that there is no motion interference between the two.

[0062] like Figure 1 , Figure 2 , Figure 4 As shown, based on the above embodiment, the mold fixing plate 200 is configured as a rectangular structure, and the mold fixing plate 200 is located within the rectangular area formed by the first wedge block 300, the first limiting plate 110, the second wedge block 500, and the second limiting plate 120.

[0063] like Figure 1 , Figure 4As shown, based on the above embodiment, the substrate 100 has a force-receiving hole 130, and the eccentric cam 700 is rotatably installed in the force-receiving hole 130. The outer edge of the eccentric cam 700 abuts against the hole wall of the force-receiving hole 130.

[0064] Based on the above embodiments, the substrate 100 is provided with a hinge shaft 140, which is set as the rotation center of the substrate 100 in the θ direction.

[0065] The hinge shaft 140 is axial in the Z-axis direction, and can be considered as the Z-axis. The substrate 100 can only rotate around the hinge shaft 140. The eccentric cam 700 is rotatably connected to the equipment or worktable via the third adjusting screw 710. The eccentric cam 700 is located inside the force-receiving hole 130 and abuts against the hole wall of the force-receiving hole 130. The eccentric cam 700 abuts against both sides of the hole wall of the force-receiving hole 130. Therefore, when the eccentric cam 700 is not rotating, the base is essentially locked by the hinge shaft 140 and the eccentric cam 700, preventing it from actively rotating around the hinge shaft 140. When the eccentric cam 700 rotates, it can force the substrate 100 to rotate around the hinge shaft 140, thereby achieving fine adjustment in the θ direction.

[0066] like Figure 1 As shown, based on the above embodiment, both the substrate 100 and the mold fixing plate 200 are provided with chip removal holes 900, and the two chip removal holes 900 are connected. The chip removal holes 900 enable the tooling to form a through structure in a local area, thereby achieving the purpose of discharging waste materials.

[0067] like Figure 1 , Figure 4 As shown, based on the above embodiment, a third elastic reset member 800 is provided between the first wedge block 300 and the base plate 100, and between the second wedge block 500 and the base plate 100. The third elastic reset member 800 is used to provide an upward force to the wedge block. After loosening the first adjusting screw 310 or the second adjusting screw 510, the first wedge block 300 or the second wedge block 500 can rise under the action of the third elastic reset member 800, so that the mold fixing plate 200 can retract smoothly.

[0068] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in this utility model embodiment are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0069] Furthermore, in this utility model, the use of terms such as "first," "second," and "a" is for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0070] In this utility model, unless otherwise explicitly specified and limited, the terms "connection," "fixing," etc., should be interpreted broadly. For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0071] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other.

[0072] However, this must be based on the premise that it can be implemented by a person skilled in the art, when the technical solution...

[0073] When the combination of these elements results in contradictions or is impossible to achieve, such a combination of technical solutions should be considered...

[0074] It does not exist and is not within the scope of protection claimed by this utility model.
