Description

Technical Field

[0001] This utility model relates to the field of tooling and fixture technology, and in particular to a tooling for flipping automotive parts. Background Technology

[0002] In the manufacturing process of automotive parts, many components, such as housings and brackets, require multi-faceted machining, inspection, or assembly. To improve production efficiency, tooling equipment is needed to fix the parts in place and to flip them to different working surfaces.

[0003] Existing flipping fixtures have structural deficiencies in achieving clamping and flipping functions. For example, many fixtures use manual screw clamps or quick clamps to fix parts. This manual clamping method relies entirely on the operator's experience and physical strength, making standardization and precise control difficult. Excessive clamping force can cause deformation and damage to thin-walled or precision parts; while insufficient clamping force may cause parts to loosen or shift during flipping, severely affecting the machining accuracy of subsequent processes.

[0004] Furthermore, existing flipping structures face a dilemma in order to accommodate the aforementioned clamping mechanisms. Some flipping structures are designed to be relatively simple, such as manual flipping via a simple pivot, but after flipping to a specific angle, such as 180 degrees, their locking devices often become complex or unreliable in positioning, causing wobbling or angular deviation due to the workpiece's own weight. On the other hand, some automated flipping and locking mechanisms that attempt to solve this problem make the entire tooling structure extremely complex and costly, and are incompatible with the unstable manual clamping method, thus failing to fundamentally solve the problem.

[0005] Existing automotive parts tooling generally suffers from inaccurate clamping force control, which can easily lead to workpiece deformation or loosening. Furthermore, the flipping and positioning structure is complex or the locking is unreliable, which directly affects the stability of processing and overall operational efficiency.

[0006] Therefore, this utility model proposes an automotive parts flipping tool to address the shortcomings of the prior art. Utility Model Content

[0007] In view of the problems of inaccurate clamping force control, easy deformation or loosening of workpieces, and complex or unreliable flipping positioning structure in the existing automotive parts flipping fixture, this utility model aims to provide an automotive parts flipping fixture with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a tooling for flipping automotive parts, including: an operating table, a flipping mechanism mounted on the operating table, and a clamping mechanism mounted on the flipping mechanism.

[0009] The flipping mechanism includes a fixed base, bearings, connecting blocks, turntables, connecting rods, circular grooves, rockers, limit plates, and fixed cylinders.

[0010] The clamping mechanism includes a hollow block, a servo motor, a slide plate, a slider, a rotating rod one, a rotating rod two, a rotating rod three, and a clamping plate.

[0011] In the specific connection relationship and structure, the fixed seat is fixedly connected to the top wall of the operating table, the outer ring of the bearing is fixed to the inner wall of the fixed seat, the connecting block is rotatably connected to the inner ring of the bearing and passes through the bearing, one end of the connecting block is fixedly connected to the turntable, the connecting rod is fixedly connected to the outer peripheral wall of the turntable, the upper end of the connecting rod is provided with a circular groove, the rocker arm is slidably connected to the inner wall of the circular groove, the front wall of the rocker arm is fixedly connected to a limit piece, and the fixed cylinder is symmetrically fixed to the top and bottom of the fixed seat.

[0012] Meanwhile, the hollow block is fixedly connected to the other end of the connecting block away from the turntable, the servo motor is set inside the hollow block, the second rotating rod is fixedly connected to the output end of the servo motor, the first rotating rod and the third rotating rod are respectively rotatably connected to the left and right ends of the second rotating rod, the slider is respectively rotatably connected to the other end of the first rotating rod and the third rotating rod away from the second rotating rod, and the slider is slidably connected to the slide plate, while the clamping plate is fixedly connected to the outer wall of the slider.

[0013] Preferably, the function of the limiting piece is that when the flipping mechanism rotates to a predetermined angle, the operator can use the pushing and pulling action of the rocker arm to make the limiting piece engage and fix it with the two fixed cylinders. In addition, as an anti-drop design, the width of the limiting piece is set to be greater than the groove width of the circular slide. This structure can effectively prevent the rocker arm from slipping out of the circular slide during operation.

[0014] Preferably, in order to achieve a smooth and symmetrical clamping action, the sliding plates are symmetrically arranged on the inner walls of both sides of the hollow block. The guiding function of the sliding plates is used to strictly limit the two sliders to move synchronously only along opposite straight lines, thus ensuring the stability of the clamping.

[0015] Preferably, the first rotating rod, the second rotating rod, and the third rotating rod together constitute a symmetrical linkage transmission mechanism. In this structure, when the second rotating rod at the center of the servo motor rotates, the rotational motion is efficiently converted into the synchronous linear motion of the two sliders moving in opposite directions or away from each other through this linkage transmission mechanism, thereby driving the clamping plate.

[0016] Preferably, in order to ensure the concentricity and stability of the flipping, the connecting block and the turntable are designed to be coaxial. They rely on the support of bearings to rotate together around their central axis. This design enables the clamping mechanism fixed on the connecting block to achieve smooth overall flipping.

[0017] Preferably, as a specific manual driving method, the operator operates a rocker arm to slide the rocker arm on the inner wall of the circular groove. This sliding action effectively transmits the force applied by the operator to the connecting rod, which then acts as a lever arm, thereby driving the turntable to rotate around the bearing and achieve flipping.

[0018] Preferably, to enhance structural rigidity and simplify assembly, the hollow block is designed to be integrally formed at the end of the connecting block away from the turntable. This integrated structure forms a high-rigidity clamping unit, which can rotate directly with the connecting block, ensuring structural strength during the flipping process.

[0019] Preferably, the clamping mechanism specifically includes two sliders and two clamping plates. When the two sliders move in opposite directions or away from each other on their respective slide plates under the drive of the servo motor, they will synchronously drive the two clamping plates fixed on them to move closer or further away, thereby realizing the clamping or release of the workpiece.

[0020] This utility model has the following beneficial effects: 1. This utility model solves the problems of poor stability, uncontrollable clamping force, and low operating efficiency in the prior art when manually clamping automotive parts by setting up a linkage transmission mechanism composed of a servo motor, a rotating rod 1, a rotating rod 2, and a rotating rod 3, which drives the slider and clamping plate sliding on the slide plate. It achieves the technical effects of automated clamping process, precise and controllable clamping force, and stable and reliable clamping.

[0021] 2. This utility model solves the problems of complex flipping positioning structure, inconvenient operation, and unreliable locking in the existing flipping fixture by setting a rocker arm, a connecting rod that slides in a circular groove, and a turntable to form a flipping drive structure. It also utilizes a limiting piece fixedly connected to the rocker arm to engage with a fixed cylinder fixedly connected to the fixed base. This achieves the technical effect of convenient flipping operation, simple structure, and stable and reliable positioning and locking after flipping.

[0022] 3. This utility model integrates the servo motor-driven clamping mechanism with the manually operated flipping mechanism. The hollow block of the clamping mechanism is integrally formed on the connecting block of the flipping mechanism, which solves the problems of poor connection between the clamping and flipping processes, bulky overall structure or single function of existing tooling. It achieves the comprehensive technical effect of compact overall structure, integrated automated clamping and convenient flipping, and improved auxiliary efficiency of automotive parts processing.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0026] Please refer to Figures 1 to 4 This utility model provides an automotive parts flipping fixture, which aims to solve the technical problems existing in the prior art. Some existing automotive parts tooling suffers from unstable manual clamping and uncontrollable clamping force when flipping parts. Furthermore, the angle positioning after flipping relies on a complex structure, which is not convenient or reliable, affecting overall operational efficiency and processing accuracy. like Figure 1 and Figure 2 As shown, an automotive parts flipping fixture includes an operating table 1, a flipping mechanism 2, and a clamping mechanism 3. The operating table 1 serves as the mounting base for the entire device. The flipping mechanism 2 is mounted on the operating table 1, and the clamping mechanism 3 is mounted on the flipping mechanism 2. The flipping mechanism 2 drives the clamping mechanism 3 to flip as a whole, and the clamping mechanism 3 is used to automatically clamp or release automotive parts. Specifically, such as Figure 1 , Figure 2 and Figure 3As shown, the flipping mechanism 2 includes a fixed base 207, a bearing 208, a connecting block 201, a turntable 206, a connecting rod 209, a circular groove 204, a rocker arm 205, a limiting piece 203, and a fixed cylinder 202. The fixed base 207 is fixedly connected to the top wall of the operating table 1. The outer ring of the bearing 208 is fixed to the inner wall of the fixed base 207. The connecting block 201 is rotatably connected to the inner ring of the bearing 208 and passes through the bearing 208. One end of the connecting block 201 is fixedly connected to the turntable 206. The connecting block 201 and the turntable 206 are coaxially arranged and rotate around their common central axis through the support of the bearing 208, thereby driving the clamping mechanism 3 to flip as a whole. The connecting rod 209 is fixedly connected to the outer peripheral wall of the turntable 206. A circular groove 204 is provided at the upper end of the connecting rod 209. The rocker arm 205 is slidably connected to the inner wall of the circular groove 204. A limit piece 203 is fixedly connected to the front wall of the rocker arm 205. The rocker arm 205 transmits the force applied by the operator to the connecting rod 209 by sliding on the inner wall of the circular groove 204. The connecting rod 209 acts as a lever arm to drive the turntable 206 to rotate around the bearing 208. The fixed cylinders 202 are symmetrically fixed to the top and bottom of the fixed base 207. The limiting piece 203 is used to engage and fix with the two fixed cylinders 202 by the pushing and pulling action of the rocker arm 205 when the flipping mechanism 2 rotates to a predetermined angle. Furthermore, the width of the limiting piece 203 is greater than the groove width of the circular slide 204 to prevent the rocker arm 205 from slipping out of the circular slide 204.

[0027] Please refer to Figure 2 and Figure 4 The clamping mechanism 3 includes a hollow block 301, a servo motor 302, a sliding plate 303, a slider 304, a first rotating rod 305, a second rotating rod 306, a third rotating rod 307, and a clamping plate 308. Hollow block 301 is fixedly connected to the other end of connecting block 201 away from turntable 206. In this embodiment, hollow block 301 is integrally formed on the end of connecting block 201 away from turntable 206 to form a rigid clamping unit that rotates with connecting block 201. The servo motor 302, serving as the power source, is located inside the hollow block 301. Rotary rod 2 306 is fixedly connected to the output end of servo motor 302. Rotary rod 1 305 and rotary rod 307 are rotatably connected to the left and right ends of rotary rod 2 306, respectively. Rotary rod 1 305, rotary rod 2 306 and rotary rod 307 constitute a symmetrical linkage transmission mechanism. The slide plates 303 are symmetrically arranged on the inner walls of both sides of the hollow block 301. The slide plates 303 are used to limit the synchronous movement of the two sliders 304 in opposite linear directions. Slider 304 is rotatably connected to the other end of rotating rod 305 and rotating rod 307 away from rotating rod 306, and the two sliders 304 are slidably connected to the corresponding slide plates 303. The clamping plate 308 is fixedly connected to the outer wall of the slider 304. When the servo motor 302 drives the rotating rod 306 to rotate, the rotational motion is converted into the synchronous linear motion of the two sliders 304 by the linkage transmission mechanism composed of the rotating rod 305 and the rotating rod 307. When the sliders 304 move towards or away from each other on the slide plate 303, they drive the two clamping plates 308 to move closer or further away synchronously, thereby realizing the stable clamping or release of the automotive parts.

[0028] As a preferred embodiment, to achieve reliable flipping positioning and operational safety, please refer to... Figure 3 The fixed cylinders 202 are symmetrically fixed to the top and bottom of the fixed base 207. The limiting piece 203 is used to engage and fix with the two fixed cylinders 202 by the pushing and pulling action of the rocker arm 205 when the flipping mechanism 2 rotates to a predetermined angle. Furthermore, the width of the limiting piece 203 is greater than the width of the groove of the circular slide 204, and the structure is used to prevent the rocker arm 205 from slipping out of the circular slide 204. As another preferred implementation, to ensure stable and synchronized clamping, please refer to... Figure 4 The slide plates 303 are symmetrically arranged on the inner walls of both sides of the hollow block 301. The slide plates 303 are used to limit the synchronous movement of the two sliders 304 in opposite linear directions. Rotary rod 1 305, rotary rod 2 306 and rotary rod 307 constitute a symmetrical linkage transmission mechanism, which is used to accurately convert the rotational motion output by the servo motor 302 into the synchronous linear motion of the two sliders 304 in opposite directions or outwards. As another preferred embodiment, to improve the rigidity of the structure and the directness of the transmission, please refer to... Figure 3 and Figure 4 The connecting block 201 is coaxially arranged with the turntable 206 and rotates around their common central axis through the support of the bearing 208. The hollow block 301 is integrally formed on the end of the connecting block 201 away from the turntable 206 to form a rigid clamping unit that rotates with the connecting block 201. The rocker arm 205 transmits the force applied by the operator to the connecting rod 209 by sliding on the inner wall of the circular groove 204. The connecting rod 209 acts as a lever arm to drive the turntable 206 to rotate.

[0029] Working principle: When it is necessary to clamp automotive parts, the servo motor 302 located inside the hollow block 301 is activated. The output of the servo motor 302 drives the second rotating rod 306 to rotate. Since the first rotating rod 305 and the third rotating rod 307 are rotatably connected to the left and right ends of the second rotating rod 306 respectively, the rotation of the second rotating rod 306 drives the two sliders 304 to move through the linkage transmission mechanism formed by the first rotating rod 305 and the third rotating rod 307. The sliders 304 are rotatably connected to the first rotating rod 305 and the third rotating rod 307. 7. The other end of the rotating rod 306 is away from the slider 304, and the slider 304 is slidably connected to the slide plate 303. The slide plate 303 is symmetrically arranged on the inner walls of both sides of the hollow block 301. The slide plate 303 restricts the slider 304 to move only along a straight track. Therefore, the rotational motion of the servo motor 302 is finally converted into the synchronous opposite motion of the two sliders 304 on the slide plate 303. The clamping plate 308, which is fixedly connected to the outer wall of the slider 304, moves closer synchronously to achieve a stable clamping of the automotive parts. After the parts are clamped, the operator operates the rocker arm 205, which slides on the inner wall of the circular groove 204 at the upper end of the connecting rod 209, transmitting the force applied by the operator to the connecting rod 209. The connecting rod 209 is fixedly connected to the outer peripheral wall of the turntable 206, and drives the turntable 206 to rotate. The turntable 206 is fixedly connected to one end of the connecting block 201, which is rotatably connected to the inner ring of the bearing 208. The outer ring of the bearing 208 is fixed to the inner wall of the fixing seat 207. 07 is fixedly connected to the top wall of the operating table 1, so that the turntable 206 and the connecting block 201 can rotate around their common axis on the bearing 208. Since the hollow block 301 of the clamping mechanism 3 is fixedly connected to the other end of the connecting block 201, the clamping mechanism 3 drives the entire automotive parts to flip. When flipped to a predetermined angle, the operator pushes and pulls the rocker arm 205, so that the limiting piece 203 on the front wall of the rocker arm 205 engages with the fixed cylinder 202 symmetrically fixed at the top and bottom of the fixed seat 207, completing the positioning and locking after flipping. Through the linkage driven by the servo motor 302, the clamping mechanism 3 achieves precise control of the clamping force of the parts and automated operation, solving the problem of unstable traditional manual clamping. At the same time, through the cooperation of the rocker arm 205, the circular slide 204, the limiting plate 203, and the fixed cylinder 202, a simple and reliable manual flipping and locking method is provided, solving the problem of complex flipping and positioning structure.
