Description

Technical Field

[0001] This application relates to the field of die casting equipment technology, and in particular to a fixture for die casting parts. Background Technology

[0002] In the subsequent processing or inspection of die-cast parts, fixtures are essential auxiliary equipment. Their main function is to stably and reliably clamp irregularly shaped parts on the worktable for precise machining or quality inspection. To accommodate the clamping requirements of different types of parts or the processing requirements of different processes for the same part, these fixtures usually need to have the function of adjusting their position on the worktable.

[0003] Currently, after position adjustment, most fixed fixtures use a manual locking method. The operator needs to first move the entire fixture to the predetermined position, and then use tools such as wrenches to tighten the fixing bolts one by one, or turn the manual lever to use friction or mechanical locking pins to fix the base of the fixture to the worktable.

[0004] However, this positioning and locking method, which relies entirely on manual operation, has significant shortcomings. In production scenarios requiring frequent workpiece changes or adjustments to processing positions, repeatedly manually loosening, moving, aligning, and locking is not only time-consuming and labor-intensive, but also severely impacts the overall efficiency of the production line. More importantly, the reliability of locking depends entirely on the operator's experience and physical strength, making it difficult to ensure that the locking force is uniform and appropriate each time. Insufficient locking force can cause vibration or slight displacement of the tooling during processing, thus affecting the final product accuracy, while excessive locking force can damage the equipment. Therefore, this utility model proposes a fixing fixture for die-cast parts to address the shortcomings of the existing technology. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a fixing fixture for die-cast parts, aiming to improve the problems of cumbersome fixture position adjustment, reliance on manual operation for locking, and low positioning reliability of some existing fixing fixtures for die-cast parts.

[0006] This utility model provides a fixing fixture for die-cast parts, including a working surface and a sliding block movably disposed inside the working surface; it also includes a motor, a turntable, a connecting arm, a main limiting rod, a rotating ring, a sliding block and a rubber block.

[0007] The motor is fixedly connected inside the sliding block as a power source. A turntable is fixedly connected to the output end of the motor. The surface of the turntable is eccentrically connected to one end of the connecting arm, forming the initial link to convert rotary motion into reciprocating motion.

[0008] Furthermore, the other end of the connecting arm is fixedly connected to the main limiting rod. A rotating ring is rotatably connected to the outer wall of the main limiting rod, a sliding block is fixedly connected to the outer wall of the rotating ring, and a rubber block is fixedly connected to the outer wall of the sliding block. Through this complete transmission chain combination from the motor to the rubber block, an automated locking action under electronic control is achieved. The rubber block can selectively abut against or disengage from the inner wall of the working surface under the drive of the sliding block.

[0009] Preferably, the main limiting rod and the sliding block together constitute part of the shifting mechanism, which also includes a limiting assembly. The limiting assembly consists of a main limiting rod and a secondary limiting rod, with the secondary limiting rod fixedly connected to the bottom of the sliding block and slidably engaged within the sliding block. The dual guiding and limiting functions of the main and secondary limiting rods ensure high stability and accuracy of the sliding block during reciprocating motion, preventing deflection or jamming.

[0010] Preferably, a pressing mechanism is fixedly connected to the top of the sliding block. The pressing mechanism includes a fixed base fixed to the top of the sliding block, and a top pressing block that is movably connected to the fixed base via an elastic component. This arrangement integrates the position adjustment locking function with the component pressing and fixing function, resulting in a compact structure and convenient operation.

[0011] Preferably, a connecting base is fixedly connected to the top of the fixed base of the pressing mechanism, and a rotating block is rotatably connected between the bottom of the top pressing block and the connecting base. This hinged structure makes the posture of the top pressing block more stable when it moves up and down.

[0012] Preferably, the rotating block and the top pressing block are connected by a telescopic block. The telescopic block, as the core force transmission and energy storage component, is designed to stretch when the top pressing block is pulled upward, providing a basis for rapid pressing.

[0013] Preferably, a spring is sleeved around the outer periphery of the telescopic block. The spring stores elastic energy simultaneously when the telescopic block is stretched, and when the top pressing block is released, the restoring force of the spring can drive the top pressing block to press down quickly, thereby achieving rapid clamping of the parts.

[0014] Preferably, the device also includes a housing. The working surface and the sliding block are both housed inside the housing, providing effective protection for the internal precision motion mechanism and improving the device's durability and adaptability to the workshop environment.

[0015] Preferably, the motor, turntable, connecting arm, rotating ring, limiting component, sliding block, and rubber block together constitute a complete shifting mechanism. The shifting mechanism and the pressing mechanism are integrated and set inside the working surface, forming two core functional modules, making the overall structure clear and the functions well-defined.

[0016] This utility model has the following beneficial effects: 1. This utility model, by setting a displacement mechanism driven by a motor, converts the rotational motion of the motor into the linear motion of the sliding block, thereby driving the rubber block to abut against the inner wall of the working surface to achieve locking. This solves the problem that the tooling position adjustment in the prior art requires manual locking, which is cumbersome and inefficient. It achieves the technical effect of automated fast locking and accurate and reliable positioning.

[0017] 2. This utility model, by setting up a pressing mechanism that utilizes the principle of spring energy storage and release, can complete energy storage by lifting the top pressing block upwards, and automatically press it down after release. This solves the problems of slow operation speed and low clamping efficiency when using lead screws and other methods to clamp parts in the prior art, and achieves the technical effect of fast clamping and simple operation, effectively shortening auxiliary time.

[0018] 3. This utility model integrates the automatic locking shifting mechanism and the rapid pressing mechanism into a single design, which are then mounted on the sliding block. This solves the problems of traditional tooling having limited functionality, separate adjustment and clamping steps, and a long overall operation process. It achieves the technical effects of compact structure, high functional integration, and high collaborative operation efficiency, thereby enhancing the equipment's adaptability to different processing tasks.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0022] Example: Reference Figures 1 to 4 This utility model provides a fixing fixture for die-cast parts, aiming to solve the problems of cumbersome position adjustment and low efficiency caused by manual operation of fixing fixtures in the prior art.

[0023] like Figure 1 and Figure 2 As shown, the device includes a housing 1, a working surface 2 housed inside the housing 1, and a sliding block 31 movably disposed inside the working surface 2. The sliding block 31 serves as a support platform, and a motor 32, which acts as a power source, is fixedly connected inside it. A turntable 33 is fixedly connected to the output end of the motor 32. One end of a connecting arm 34 is eccentrically connected to the surface of the turntable 33, and the other end of the connecting arm 34 is fixedly connected to a main limiting rod 361. A rotating ring 35 is rotatably connected to the outer wall of the main limiting rod 361, and a sliding block 37 is fixedly connected to the outer wall of the rotating ring 35. A rubber block 38 is fixedly connected to the outer wall of the sliding block 37. The motor 32 drives the turntable 33 to rotate, and through the linkage of the connecting arm 34, the main limiting rod 361, and the rotating ring 35, the sliding block 37 and the rubber block 38 are driven to reciprocate horizontally, so that the rubber block 38 can selectively abut against or detach from the inner wall of the working surface 2, thereby realizing the rapid locking and unlocking of the entire sliding block 31.

[0024] The shifting mechanism 3 includes a motor 32, a turntable 33, a connecting arm 34, a rotating ring 35, a sliding block 37, a rubber block 38, and a limiting component 36 for guiding and limiting the movement; please refer to the following for details. Figure 2 The internal core structure of the shifting mechanism 3 will be described in detail below: The limiting assembly 36 includes a main limiting rod 361 and a secondary limiting rod 362. The main limiting rod 361 is slidably inserted inside the sliding block 31 and is used to perform horizontal linear movement under the drive of the connecting arm 34. The secondary limiting rod 362 is fixedly connected to the bottom of the sliding block 37 and is slidably engaged inside the sliding block 31. The combined function of the main limiting rod 361 and the secondary limiting rod 362 is to provide precise guidance and double limiting for the movement of the sliding block 37.

[0025] Reference Figure 1 and Figure 3A pressing mechanism 4 is fixedly connected to the top of the sliding block 31. The pressing mechanism 4 includes a fixed base 41 fixed to the top of the sliding block 31, and a top pressing block 46 that can be moved up and down above the fixed base 41 by an elastic component. The top pressing block 46 is used to directly contact and press the parts.

[0026] Reference Figure 3 and Figure 4 A connecting base 42 is fixedly connected to the top of the fixed base 41; a rotating block 43 is rotatably connected between the bottom of the top pressing block 46 and the connecting base 42; the rotating block 43 and the top pressing block 46 are connected by a telescopic block 44, and a spring 45 is sleeved on the outer periphery of the telescopic block 44; by pulling the top pressing block 46 upward, the telescopic block 44 is stretched, and the spring 45 is stretched and stores elastic force. After release, the restoring force of the spring 45 drives the top pressing block 46 to move downward, thereby completing the pressing and fixing of the material.

[0027] The implementation principle of this application embodiment is as follows: When it is necessary to lock or unlock the sliding block 31, the motor 32 inside the sliding block 31 is started; the motor 32 drives the fixedly connected turntable 33 to rotate, the turntable 33 drives the connecting arm 34 to move through the eccentric setting, the connecting arm 34 drives the main limit rod 361, the main limit rod 361 drives the rotating ring 35 on the outer wall, and then drives the fixedly connected sliding block 37 to move horizontally; during the movement, the main limit rod 361 and the secondary limit rod 362 in the limit assembly 36 jointly provide guidance for the sliding block 37; the sliding block 37 drives the rubber block 38 on the outer wall to move synchronously, when it is necessary to lock, the sliding block 37 expands outward, driving the rubber block 38 to tightly abut against the inner wall of the working surface 2, and using friction to complete the stable positioning of the sliding block 31, solving the problem of cumbersome and unreliable manual locking.

[0028] When it is necessary to press and fix the parts, pull up the top pressing block 46 of the pressing mechanism 4; the top pressing block 46 drives the telescopic block 44 to move upward through the rotating block 43 on the connecting base 42. During the stretching process, the telescopic block 44 also drives the spring 45 on the outer periphery to stretch, thereby storing elastic potential energy; after the parts are placed in place, release the top pressing block 46. Under the restoring force of the spring 45, the top pressing block 46 moves downward quickly, pressing and fixing the parts on the fixed base 41, realizing a quick clamping operation.
