Description

Technical Field

[0001] This application relates to the field of motor housing fixture technology, specifically a production fixture for automotive micro motor housings. Background Technology

[0002] In the manufacturing process of automotive micro motors, the molding process of the housing is crucial. Currently, automotive micro motor housings are mainly produced by stamping disc-shaped blanks. The fixture device mainly relies on the coordinated operation of cylinders and fixtures to achieve the intermittent movement of materials to the stamping equipment. Specifically, the cylinders provide power to drive the fixtures to accurately transport the disc-shaped blanks one by one to the stamping position according to a predetermined rhythm and stroke, so as to ensure the stable operation of the stamping process.

[0003] However, in actual stamping production, it is usually necessary to drip lubricant or release agent onto the conveyor support table to facilitate the smooth demolding of subsequent workpieces from the mold. Although the friction between the bottom of the workpiece and the support table during the movement of the workpiece allows the auxiliary material to be automatically applied to the bottom of the workpiece, the diameter of the disc-shaped workpiece is usually much larger than the width of the support table. The purpose of the narrow width of the support table is to avoid interfering with the clamping action of the fixture and to ensure that the material can move in a straight line intermittently. This results in a limited contact area between the bottom of the workpiece and the support table, and the auxiliary material cannot be evenly applied to the bottom of the workpiece. Uneven application not only affects the demolding effect, but may also cause problems such as jamming and damage to the workpiece during the demolding process, reducing the product qualification rate. Utility Model Content

[0004] To address the shortcomings of existing technologies, this application provides a production fixture for automotive micro motor housings, which has advantages such as simultaneous application of release agent during the conveying process, thus solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: a production fixture for a micro motor housing for automobiles, comprising a support platform and fixture platforms respectively arranged on both sides, wherein a nozzle is fixedly installed inside the support platform along its length direction, and a set of nozzles arranged along the height direction of the support platform are fixedly connected to the outer surface of the nozzle, and a through groove is opened on the upper surface of the support platform, and a set of nozzles is located below the through groove. Above the two clamping platforms are two symmetrically arranged clamping mechanisms; The clamping mechanism includes a movable plate arranged along the length of the support platform. The upper surface of the movable plate is provided with multiple sets of linearly arranged swing arms. Each pair of adjacent swing arms has a figure-eight structure. The end of each swing arm near the support platform is rotatably connected to a rotating shaft along the height direction of the support platform. Each rotating shaft has a limit roller fixedly connected to its outer surface. Each limit roller has an embedded groove on its outer surface. The top end of each rotating shaft is fixedly connected to the output end of an external motor. Each motor is connected to an external control system.

[0006] Furthermore, the clamping mechanism also includes a long-stroke cylinder, the output end of which is fixedly connected to the moving plate, and the long-stroke cylinder is fixedly connected to the upper surface of the clamping platform.

[0007] Through the above solution, the long-stroke cylinder can provide a large stroke of linear motion, meet the conveying requirements of blanks of different sizes, and ensure the stability of the conveying process.

[0008] Furthermore, the bottom of the movable plate is slidably connected to the upper surface of the clamping platform.

[0009] The above scheme provides a certain guiding function for the moving plate, preventing it from shifting during movement.

[0010] Furthermore, the clamping mechanism also includes a set of bidirectional cylinders arranged along the length of the support platform. Each bidirectional cylinder is fixedly connected to the moving plate, and a slide rod is fixedly connected to the output end of each bidirectional cylinder. The clamping mechanism also includes a sliding groove on each swing arm along its length, and each sliding rod is slidably connected to its corresponding sliding groove.

[0011] Through the above scheme, the extension and retraction of the bidirectional cylinder causes the slide bar to slide in the slide groove, thereby driving the swing arm to rotate around the rotating shaft and realize the clamping of the disc blank.

[0012] Furthermore, a support frame is fixedly installed at the bottom of the support platform.

[0013] The above solution can provide stable support for the platform.

[0014] Furthermore, a storage tank is installed in the middle of the support frame along its length for storing the release agent. A pump body is installed above the storage tank, with the input end of the pump body fixedly connected to the storage tank and the output end of the pump body fixedly connected to the spray pipe.

[0015] Through the above scheme, the pump body extracts the release agent from the storage tank and delivers it to the spray pipe, and then sprays it evenly from the nozzle. Combined with the rotation of the ingredients during the movement, the release agent can evenly cover the contact surface between the ingredients and the mold cavity, ensuring the demolding effect.

[0016] Furthermore, each of the embedded slots has anti-slip grooves on its surface.

[0017] The above solution increases the friction between the limiting roller and the edge of the disc blank, further preventing slippage during the rotation of the blank and ensuring stable rotation of the blank, thereby allowing the release agent to be evenly applied.

[0018] Compared with the prior art, the technical solution of this application has the following beneficial effects: This production fixture for automotive micro motor housings features a spray pipe and nozzle installed inside the support platform. In conjunction with the fixture mechanism, the blank rotates automatically during the conveying of the disc blank. Simultaneously, the nozzle evenly sprays the release agent onto the contact surface between the blank and the die cavity, thereby ensuring the demolding effect and effectively reducing problems such as workpiece jamming and damage during demolding, thus improving the product qualification rate. By setting a long-stroke cylinder to drive the moving plate, in conjunction with the clamping mechanism, the purpose of intermittently moving and conveying materials can be achieved, ensuring continuous stamping of subsequent stamping equipment and guaranteeing production efficiency.

Detailed Implementation

[0021] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0022] Please see Figures 1-8 This embodiment of a production fixture for a micro motor housing for automobiles includes a support platform 1 and fixture platforms 2 respectively arranged on both sides. The fixture is characterized in that: a nozzle 3 is fixedly installed inside the support platform 1 along its length direction, a set of nozzles 4 arranged along the height direction of the support platform 1 is fixedly connected to the outer surface of the nozzle 3, a through groove 5 is opened on the upper surface of the support platform 1, a set of nozzles 4 is located below the through groove 5, and a support frame 7 is fixedly installed at the bottom of the support platform 1 to stably support the support platform 1.

[0023] Above the two clamping platforms 2 are two symmetrically arranged clamping mechanisms 6. Each clamping mechanism 6 includes a movable plate 601 arranged along the length of the support platform 1. The upper surface of the movable plate 601 is provided with multiple sets of linearly arranged swing arms 602. Every two adjacent swing arms form a V-shape. The end of each swing arm closest to the support platform 1 is rotatably connected to a rotating shaft 603 along the height direction of the support platform 1. The outer surface of each rotating shaft 603 is fixedly connected to a limiting roller 604. The outer surface of each limiting roller 604 is provided with an embedding groove 605. The top of each rotating shaft 603 is divided into... Do not connect the motor output to the external motor. Each motor is connected to the external control system. The servo motor has a speed accuracy of ±0.01%. The synchronous rotation of the motor is achieved through precise programming of the control system. Due to the low accuracy error, even if some limit rollers 604 slip at the edge of the external disc feeding, the blank can still be driven to rotate during the movement. With the linear arrangement of atomizing nozzles 4 at the bottom, during the material conveying process, release agent is sprayed on the contact surface between the feeding and the cavity of the die, which facilitates demolding and reduces damage to the workpiece surface.

[0024] The clamping mechanism 6 also includes a long-stroke cylinder 606. The output end of the long-stroke cylinder 606 is fixedly connected to the moving plate 601, and the long-stroke cylinder 606 is fixedly connected to the upper surface of the clamping platform 2. The long-stroke cylinder 606 can provide a large stroke of linear motion to meet the conveying requirements of blanks of different sizes, while ensuring the stability of the conveying process. The bottom of the moving plate 601 is slidably connected to the upper surface of the clamping platform, which plays a certain guiding role for the moving plate 601 and prevents it from deviating during movement. The clamping mechanism 6 also includes... A set of bidirectional cylinders 607 are arranged along the length of the support platform 1. Each bidirectional cylinder 607 is fixedly connected to the moving plate 601. The output end of each bidirectional cylinder 607 is fixedly connected to a slide rod 609. The clamping mechanism 6 also includes a slide groove 608 opened along the length of each swing arm. Each slide rod 609 is slidably connected to its corresponding slide groove 608. The extension and retraction of the bidirectional cylinders 607 causes the slide rod 609 to slide in the slide groove 608, thereby driving the swing arm to rotate around the rotating shaft 603 to achieve the clamping of the disc blank.

[0025] A storage tank 8 is installed along the length of the support frame 7 in the middle for storing the release agent. A pump body 9 is installed above the storage tank 8. The input end of the pump body 9 is fixedly connected to the storage tank 8, and the output end of the pump body 9 is fixedly connected to the spray pipe 3. The pump body 9 draws the release agent from the storage tank 8 and delivers it to the spray pipe 3, and then sprays it evenly from the nozzle 4. With the rotation of the material during the movement, the release agent can evenly cover the contact surface between the material and the mold cavity, ensuring the demolding effect. Each embedded groove 605 has an anti-slip groove 608 on its surface, which increases the friction between the limiting roller 604 and the edge of the disc blank, further preventing slippage during the rotation of the blank and ensuring that the blank can rotate stably, thereby making the release agent evenly covered.

[0026] The working principle of the above embodiment is as follows: the control system issues a command to start the bidirectional cylinder 607 to work. The extension and retraction of the bidirectional cylinder 607 drives the slide rod 609, which is fixedly connected to its output end, to move. Since each slide rod 609 is slidably connected to the corresponding swing arm with a groove 608 opened along its length direction, when the slide rod 609 slides in the groove 608, it will drive the swing arm to rotate around the rotating shaft 603. Every two adjacent swing arms form a figure-eight structure. Under the action of the bidirectional cylinder 607, the swing arm gradually approaches and clamps the edge of the disc blank, thereby achieving stable clamping of the disc blank.

[0027] The control system starts the long-stroke cylinder 606. The output end of the long-stroke cylinder 606 is fixedly connected to the moving plate 601. The long-stroke cylinder 606 pushes the moving plate 601 to move linearly along the length of the support platform 1. During the material conveying process, the control system controls the motor connected to the top of each rotating shaft 603 to drive the limiting roller 604 to rotate. The embedded groove 605 on the outer surface of the limiting roller 604 contacts the edge of the disc blank, thereby driving the blank to rotate automatically during the movement. At the same time, the control system controls the pump body 9 to start working. The pump body 9 extracts the release agent from the storage tank 8 and delivers it to the spray pipe 3. The release agent is delivered to the nozzle 4 through the spray pipe 3 and sprayed evenly by the nozzle 4. It is sprayed on the contact surface between the disc blank and the cavity of the die above the through groove 5. Because the blank rotates continuously during the movement, the release agent can be evenly covered on the contact surface between the material and the cavity of the die, ensuring the demolding effect.
