Abstract
Description
Technical Field
[0001] This utility model relates to the field of positioning tooling technology, and in particular to a forming positioning tooling. Background Technology
[0002] Positioning fixtures are specialized auxiliary devices used in industrial production to fix and position workpieces, ensuring the accuracy of assembly or machining positions. Their core function is to guarantee operational consistency and product quality by restricting the workpiece in spatial directions (such as the X / Y / Z axes).
[0003] The side cover of the power battery is an important component of the power battery structure. Its main functions include protecting the internal components of the battery, preventing battery leakage, and providing electrical insulation. It is made of metal materials such as aluminum alloy, which has advantages such as excellent machinability, corrosion resistance and recyclability. The side cover produced by stamping process has good structural integrity, can effectively reduce weight, and ensure stable operation of the battery.
[0004] When stamping the side cover of a power battery, the cut sheet material is fed into a stamping machine. The side cover is formed by stamping between the molds that match the sheet material. This method requires precise alignment of the sheet material on the lower mold so that the upper mold can process it accurately. The whole process requires manual feeding, alignment and positioning. This method is physically demanding for the operator, resulting in low production efficiency and is also unsafe.
[0005] To address the aforementioned issues, a forming and positioning fixture is proposed. Utility Model Content
[0006] The main purpose of this utility model is to provide a forming and positioning tooling that solves the problems mentioned in the background art.
[0007] The objective of this utility model can be achieved by adopting the following technical solution:
[0008] A forming and positioning fixture includes a feeding mechanism, a discharging mechanism and a stamping mechanism, wherein a positioning mechanism is fixedly installed between the feeding mechanism and the discharging mechanism;
[0009] The positioning mechanism includes a frame integrally connected to the feeding mechanism and the unloading mechanism. A cross-shaped positioning groove is provided in the top inner wall of the frame. A positioning push plate is slidably arranged in the positioning groove. A positioning frame is detachably fixed to the top of the frame. A guide groove is provided through the positioning frame to limit the sliding of the positioning push plate. A reserved hole is formed through the center of the top of the positioning frame. A detachable lower mold is installed in the reserved hole.
[0010] Furthermore, the positioning push plates are threadedly connected by a first bidirectional screw and a second bidirectional screw, both of which are rotatably supported on the frame by a bracket.
[0011] Furthermore, a drive motor is installed at one external end of the first bidirectional screw and the second bidirectional screw. Several ejection springs are fixed in the mold cavity of the lower mold. An ejection template that slides along the mold cavity is fixedly connected to the top of the ejection spring. The top of the ejection template is 2-3mm higher than the top of the lower mold.
[0012] Furthermore, a pressure sensor is embedded in the inner wall of the positioning push plate, and a stamping mechanism is also fixed on both sides of the outer side of the frame.
[0013] Furthermore, the stamping mechanism includes a hydraulic cylinder, a guide rod, and an upper die, the upper die being adapted to the lower die, and a laser sensor being fixedly mounted through the upper die.
[0014] Furthermore, the outer walls of the feeding mechanism are bolted with a material gripping mechanism, which includes a gantry frame, an electric cylinder, a suction cup claw, and an electric push rod.
[0015] The beneficial technical effects of this utility model are as follows:
[0016] This invention utilizes a positioning fixture comprised of a positioning frame, a positioning push plate, a first bidirectional screw, and a second bidirectional screw. This fixture enables automatic double-sided alignment and positioning of the incoming sheet metal at the top center of the lower mold, aligning it with the upper mold. This allows for rapid stamping of the sheet metal into a battery side cover. The formed battery side cover is then ejected by the ejector plate and fed into the unloading mechanism for automatic discharge, replacing manual feeding, positioning, and unloading. This significantly improves the processing efficiency of the stamping equipment. Attached Figure Description

[0023] To enable those skilled in the art to understand the technical solution of this utility model more clearly, the present utility model will be further described in detail below with reference to the embodiments and accompanying drawings, but the implementation of this utility model is not limited thereto.
[0024] like Figures 1-4 As shown, this embodiment provides a forming and positioning fixture, including a feeding mechanism 1, a discharging mechanism 2, and a stamping mechanism 3. A positioning mechanism 4 is fixedly installed between the feeding mechanism 1 and the discharging mechanism 2. The positioning mechanism 4 includes a frame 403 integrally connected to the feeding mechanism 1 and the discharging mechanism 2. A cross-shaped positioning groove 403a is opened in the inner wall of the top of the frame 403. A positioning push plate 402 is slidably arranged in the positioning groove 403a. A positioning frame 404 is detachably fixed to the top of the frame 403. A guide groove 404b for limiting the sliding of the positioning push plate 402 is opened through the positioning frame 404. A reserved hole 404a is formed through the center of the top of the positioning frame 404. A detachable lower mold 401 is installed in the reserved hole 404a.
[0025] In the above structure, the feeding mechanism 1 consists of a clamping roller and an external drive unit, which is used to clamp and transport the sheet metal to be stamped to the stamping mechanism 3 and the positioning mechanism 4. The unloading mechanism 2 consists of a single set of conveying rollers and a drive unit, which is used to send the formed battery side cover out of the equipment.
[0026] The positioning groove 403a is used to limit the directional movement of the bottom of the positioning push plate 402, and the guide groove 404b is used to limit the directional movement of the middle part of the positioning push plate 402, thus improving the ability of the positioning push plate 402 to move linearly.
[0027] The lower die 401 can be disassembled and replaced through the reserved hole 404a to adapt to the installation and use of stamping dies of different sizes.
[0028] The positioning push plates 402 are threadedly connected by a first bidirectional screw 405 and a second bidirectional screw 406. Both the first bidirectional screw 405 and the second bidirectional screw 406 are rotatably supported on the frame 403 by a bracket. The first bidirectional screw 405 and the second bidirectional screw 406 are screws composed of opposing positive and negative threads. When rotating, they can drive the positioning push plates 402 on both sides to move synchronously in opposite directions, thereby pushing the plate to gather and adjust towards the middle. The length and width of the plate are adapted to the lower mold 401. Therefore, when the positioning push plates 402 are aligned, they can push the outer edge of the plate to align with the edge of the lower mold 401.
[0029] A drive motor 407 is installed on the outer end of the first bidirectional screw 405 and the second bidirectional screw 406. Several ejection springs 401b are fixed in the cavity of the lower mold 401. The top of the ejection springs 401b is fixedly connected to the ejection template 401a that slides along the mold cavity. The top of the ejection template 401a is 2-3mm higher than the top of the lower mold 401. After the stamping mechanism 3 presses the sheet metal into the cavity of the lower mold 401, the ejection template 401a, which is pushed up by the ejection springs 401b, is pushed out to the top. The depth of the inner cavity of the lower mold 401 is sufficient for the stamping and shaping of the sheet metal after the ejection template 401a is pressed in with the sheet metal. After the sheet metal is stamped at this position, it is initially shaped into a concave structure with an internal concavity and a flat surface on all sides. Subsequent processes will then perform punching and grooving.
[0030] The inner wall of the positioning push plate 402 is fitted with a pressure sensor 402a. The outer sides of the frame 403 are also fitted with a stamping mechanism 3. The pressure sensors 402a are paired up in a set. When the values of the two sets are the same, the plate positioning adjustment is completed.
[0031] The stamping mechanism 3 includes a hydraulic cylinder, a guide rod, and an upper die. The upper die and the lower die 401 are adapted to each other. A laser sensor 6 is also fixed through the upper die. When the sheet metal enters the positioning mechanism 4, it blocks the beam of the laser sensor 6. The light path of the reflected beam changes. After the processor identifies the corresponding electrical signal, it starts the positioning mechanism 4 to make adjustments. Then, it starts the next execution action through the end signal controller.
[0032] The outer walls of the unloading mechanism 2 are bolted with a gripping mechanism 5. The gripping mechanism 5 includes a gantry frame, an electric cylinder, a suction cup claw, and an electric push rod. After the stamping mechanism 3 completes its action, it rises to its maximum position, which facilitates the suction cup claw and the electric push rod to enter the bottom of the upper mold. The electric push rod lowers the suction cup claw into the groove of the formed battery side cover to grip and suck it up. It then returns along the original path and is placed on the conveyor roller of the unloading mechanism 2.
[0033] The working principle of this device is as follows: When in use, this device is connected to an external power supply and an external control device.
[0034] The feeding mechanism 1 uses opposing rotating clamping rollers to feed the sheet metal into the positioning mechanism 4. When the sheet metal is fed into the top of the lower mold 401 of the positioning mechanism 4, the front end is abutted by a set of positioning push plates 402 directly in front, and the tail end falls freely into the top of the lower mold 401 and is located directly above the ejection template 401a. At this time, the sheet metal is directly above the ejection template 401a, triggering the laser sensor 6 to identify the entry of the sheet metal. The external controller then sequentially starts the positioning mechanism 4, the stamping mechanism 3, and the gripping mechanism 5 to work in the set order.
[0035] In this process, the positioning mechanism 4 starts two sets of drive motors 407 to drive the first bidirectional screw 405 and the second bidirectional screw 406 to rotate synchronously, thereby driving the positioning push plate 402 to move along the guide groove 404b and the positioning groove 403a, so as to realize the positioning adjustment of the plate that exceeds the edge of the lower mold 401, aligning the plate with the edge of the lower mold 401 and the center aligned. At this time, the pressure sensor 402a located on the side wall of the positioning push plate 402 is in a balanced state and the data of each pair is equal.
[0036] Next, the stamping mechanism 3 presses down on the upper mold to extrude the sheet metal into the mold cavity of the lower mold 401. The stamping mechanism 3 rises and lifts up, and the formed battery side cover is bounced up to the top of the lower mold 401 by the ejection plate 401a and the ejection spring 401b. The electric cylinder of the gripping mechanism 5 sends the suction cup claw into the top of the formed battery side cover. The electric push rod of the claw lowers the suction cup to grab the battery side cover and returns it to the initial position. The battery side cover is then released onto the unloading mechanism 2 and sent out of the equipment.
[0037] With the above structure, the material can be automatically fed into the stamping mechanism 3 and automatically aligned and positioned in the mold to achieve automatic stamping, reducing manual operation and improving the production efficiency of the equipment.
[0038] The above are merely further embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope disclosed by this utility model, based on the technical solution and concept of this utility model, shall fall within the protection scope of this utility model.
[0039] All standard parts used in this application can be purchased from the market, and can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art. The control method is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art and is common knowledge in the field. Since this application is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail in this application.
