Description
Technical Field
[0001] This utility model relates to the technical field of seat lock production equipment, specifically to a riveting device for automotive seat lock production equipment. Background Technology
[0002] The overall function of the riveting device in the automotive seat lock production equipment is to perform high-precision, high-efficiency, and high-consistency hole processing for the core components of automotive seat locks. By integrating mechanical support, precise positioning, automated execution, and auxiliary support systems, it ensures that the processed holes meet the assembly and safety performance requirements of the seat lock.
[0003] A single seat lock involves 3-6 riveting points. The rivets must penetrate both the metal sheet and the internal moving parts. The riveting accuracy directly determines the fit clearance between the lock hook and the stop hook, as well as the triggering sensitivity. In the current production of car seat locks, the riveting device mostly adopts the form of positioning tooling and stamping riveting, but it lacks an active clamping and anti-movement mechanism for the workpiece. Under the action of riveting impact force, it is easy to produce elastic deformation or slight displacement, resulting in the misalignment of the rivet hole, which in turn leads to the risk of lock hook jamming or unlocking failure. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a riveting device for automobile seat lock production equipment, which addresses the shortcomings of the prior art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a riveting device for an automotive seat lock production equipment, comprising a frame, an indexing turntable rotatably mounted on the frame, a plurality of clamps for placing products on the indexing turntable, and a riveting assembly for riveting products on the clamps on the outer periphery of the frame, characterized in that: the riveting assembly includes a frame body disposed on the outer periphery of the indexing turntable, a riveting drill bit disposed on the side of the frame body facing the indexing turntable, and a mounting platform for mounting a clamping assembly disposed on the side of the frame facing the clamps, the clamping assembly being able to press and fix the products during riveting.
[0006] Using the above technical solution, the indexing turntable, which rotates on the frame, transports the product placed on the fixture to the corresponding processing position of the riveting assembly. When the product reaches the riveting position, the clamping assembly on the mounting table facing the fixture moves before riveting, applying pressure to the product on the fixture to achieve pressing and fixing. Subsequently, the riveting drill bit on the outer frame of the indexing turntable performs riveting processing on the pressed and fixed product. Through the active pressing and fixing action of the clamping assembly during product riveting, the elastic deformation or slight displacement of the product under the riveting impact force can be directly limited, thereby reducing the rivet hole alignment deviation caused by workpiece movement and reducing the risk of jamming or unlocking failure caused by abnormal clearance between the locking hook and the stop hook.
[0007] The riveting device of the above-mentioned car seat lock production equipment can be further configured as follows: the clamping assembly includes a drive seat mounted on the upper end of the mounting platform, the top of the drive seat is provided with a drive frustum, the center of the drive frustum is provided with a central shaft that can rotate and be raised and lowered, the end of the central shaft is sleeved with a first connecting arm, the end of the first connecting arm is provided with a second connecting arm, and the bottom of the second connecting arm is provided with an abutment block that abuts against the product.
[0008] Using the above technical solution, the drive seat installed on the upper part of the mounting platform provides support for the overall structure. The central shaft of the drive frustum at the top of the drive seat rotates and moves up and down. The rotation of the central shaft can adjust the horizontal position of the first connecting arm sleeved at its end, so that the first connecting arm drives the second connecting arm to move in the horizontal direction, thereby positioning the abutment block at the bottom of the second connecting arm to the corresponding position of the product to be riveted. When the central shaft moves up and down, through the transmission between the first connecting arm and the second connecting arm, the abutment block is driven to descend in the vertical direction until the abutment block contacts the product surface and applies pressure, thereby pressing and fixing the product.
[0009] The riveting device of the above-mentioned automotive seat lock production equipment can be further configured as follows: the frame includes a plurality of mounting plates vertically arranged on the machine frame, the mounting plates are provided with mounting grooves for mounting the fixing plates, the riveting drill bit includes a drill body connecting block provided on one side of the fixing plate, the bottom of the drill body connecting block is provided with a retractable riveting head, and the top of the drill body connecting block is provided with a first driving member that can drive the riveting head to rotate.
[0010] Using the above technical solution, several mounting plates vertically set on the frame form a rigid support frame. The mounting grooves between the mounting plates are used to fix the lateral position of the drill body connecting block. Through the cooperation of the mounting grooves and the fixing plates, the drill body connecting block and the product riveting point on the clamp below maintain a preset longitudinal alignment relationship. The first driving component at the top of the drill body connecting block outputs rotational power to drive the bottom rivet head to rotate around its own axis. At the same time, the rivet head can extend and retract along the axial direction. During the rotation, the axial extension and retraction apply continuous pressure to the rivets on the product, causing the rivets to undergo plastic deformation under the combined action of rotation and extrusion, thereby realizing the riveting and fixing of various parts of the product.
[0011] The riveting device of the aforementioned automotive seat lock production equipment can be further configured as follows: the indexing turntable includes a turntable body and a second driving component disposed at the bottom of the turntable body to drive the turntable body to rotate; a first detection sensor is mounted on the mounting frame; the first detection sensor can detect the placement of the fixture at any point; the frame is provided with connecting columns on both sides of the fixture detected by the first sensor; the end of the connecting column is provided with a mounting block for mounting a second sensor; the second sensor and the first sensor form a three-directional detection.
[0012] Using the above technical solution, the disc body serves as the supporting foundation, and the second driving component at its bottom provides rotational power, driving the disc body to rotate the fixture around the central axis, thereby realizing the transfer of products between different processing stations; the first detection sensor set by the mounting frame is used to detect the placement of the product on any fixture; connecting columns are set on both sides of the fixture detected by the first detection sensor on the frame, and the mounting blocks at the ends of the connecting columns are used to fix the second sensor, so that the second sensor and the first detection sensor form a three-way detection, confirming the placement status of the product in the fixture from different angles.
[0013] The riveting device of the above-mentioned automotive seat lock production equipment can be further configured as follows: the clamp includes a clamp base plate fixedly installed on the disc body, the top of the clamp base plate is provided with a plurality of placement blocks, the top of the placement blocks is provided with a placement protrusion for the product to be placed, and the clamp base plate is provided with abutment posts between the placement blocks for the product to abut against the product and move axially.
[0014] Using the above technical solution, the clamp base plate fixedly installed on the disc provides a rigid support foundation for the overall structure. Several placement blocks set on its top are used to support the product. The placement protrusions on the top of the placement blocks cooperate with the positioning holes, grooves and other structures preset on the bottom or inside of the product to achieve the initial lateral and circumferential positioning of the product on the clamp. At the same time, the abutment post of the clamp base plate located between the placement blocks directly abuts against the axial end face of the product when the product is placed on the placement block. The rigid blocking effect of the abutment post restricts the axial movement of the product.
[0015] The riveting device of the above-mentioned car seat lock production equipment can be further configured as follows: the mounting plate is provided with adjustment plates on both sides, the mounting platform is installed on one side of the mounting plate through the adjustment plates, both the adjustment plates and the mounting plate are provided with adjustment grooves for adjusting the vertical position of the mounting platform, and the adjustment plates are provided with a plurality of mounting holes for mounting the mounting platform.
[0016] Using the above technical solution, the mounting plate serves as the basic support component. Adjustable plates on both sides of the mounting plate connect the mounting platform and the mounting plate. The mounting platform is mounted on one side of the mounting plate via the adjustable plates. Both the adjustable plates and the mounting plate have adjustable grooves, which are elongated grooves extending vertically. This allows the mounting platform to move vertically along the length of the adjustable groove using fasteners, thereby adjusting the vertical height of the mounting platform to accommodate the vertical position requirements of the mounting platform's supporting components for products of different thicknesses or specifications. Several mounting holes on the adjustable plates are used to fix the mounting platform to the mounting plate after it is adjusted to the target vertical position, by fasteners passing through the corresponding height mounting holes, thus achieving rigid locking of the vertical position of the mounting platform.
[0017] The beneficial effects of this utility model are as follows: The clamping component on the mounting platform facing the fixture can directly limit the elastic deformation or slight displacement of the product under the riveting impact force through the active pressing and fixing action of the clamping component during product riveting, thereby reducing the rivet hole alignment deviation caused by workpiece movement.
