Description

Technical Field

[0001] This utility model belongs to the field of home appliance parts processing technology, and relates to a convenient clamping fixture for home appliance parts. Background Technology

[0002] Existing clamping and machining methods for home appliance components suffer from significant technical shortcomings in precise dimensional positioning and clamping. The core issue stems from the insufficient adaptability of traditional fixture designs to complex geometries, material properties, and dynamic machining loads. Since many components employ thin-walled, curved, or irregularly shaped structures, traditional mechanical clamping systems struggle to achieve uniform contact, leading to uneven clamping force distribution. This can easily cause localized plastic deformation or elastic rebound, resulting in offset of the machining reference surface or dimensional deviations. The root cause lies in the non-conformal matching between the fixture contact surface and the workpiece surface, and the lack of real-time feedback and dynamic adjustment capabilities in the clamping mechanism. Conventional solutions to these deficiencies include using high-precision locating pins in conjunction with hydraulic force-enhancing mechanisms to strengthen clamping stability, or introducing modular fixture platforms to improve compatibility. However, the former suffers from high maintenance costs due to the complexity of the hydraulic system and is difficult to adapt to the needs of small-batch flexible production; while the latter expands its applicability through adjustable components, the time-consuming mechanical structure adjustments increase clamping auxiliary time. Therefore, a convenient clamping fixture for home appliance components is urgently needed to solve these problems. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a convenient clamping fixture for household appliance parts, and to solve the problems mentioned in the background technology.

[0004] This utility model is achieved through the following technical solution: a convenient clamping fixture for home appliance parts, including: a side support plate and an electric cylinder 2. The right side of the side support plate is provided with two sets of connecting seats for connecting and fixing with clamping rods.

The support components include a movable seat and a scale. The movable seat has a rectangular cross-section when viewed from above. The upper front and rear sides of the movable seat are respectively provided with a set of slide rails for guiding the left and right movement of the active bracket. In actual use, the side support plates are first fixed to the two sets of connecting seats with bolts to ensure the stability of the vertical reference plane. Then, the clamping rod is installed on the right side of the connecting seat, and a mesh reinforcement structure is formed by embedding reinforcing support plates through slots. A rubber flexible block is fitted at the end for cushioning protection. The lower support seat is connected via… The second slide rail connects to the bottom of the side support plate. The movable seat of the support component slides laterally along the second slide rail. It integrates an inner support seat and an inner support bar with a positioning suction cup. The position is locked by a locking buckle and the horizontal accuracy is adjusted by a scale. The first slide rail is installed on the top of the support component. The first electric cylinder drives the active bracket to achieve lateral clamping action. The first slide rail and the lower guide seat form a lifting mechanism. The vertical movement is controlled by the second electric cylinder, forming a multi-axial adjustment capability. During assembly, the parallelism of each slide rail must be ensured. Then, by adjusting the coordinated clamping capability of the clamping rod and the active bracket, the composite clamping effect of the negative pressure adsorption of the positioning suction cup and the elastic support of the flexible block is ensured to meet the rapid positioning needs of different specifications of home appliance parts.

[0008] In a preferred embodiment, the length of the slide rail is two-thirds of the length of the movable seat, and the two sets of slide rails are located on the upper right side of the movable seat. The upper left side of the movable seat is provided with two sets of inner support seats for supporting the lower end of the appliance parts to be clamped. The inner support seats are an arc-shaped concave structure.

[0009] As a preferred embodiment, each set of inner support bases has two sets of inner support strips at the lower inner side to improve the anti-slip effect on the lower end of the appliance parts to be clamped.

The right telescopic end of the second electric cylinder is fixed to the lower guide seat by bolts. The telescopic stroke length of the second electric cylinder is less than the top-view cross-sectional length of the slide rail 2. First, the operator places the part to be clamped on the arc surface of the inner support seat on the left side of the movable seat. Its concave structure initially fits the bottom contour of the part. Then, the front locking buckle is released, and the distance between the two sets of inner support seats is symmetrically adjusted according to the scale markings so that the anti-slip rubber on the surface of the inner support strip contacts the part, completing the initial anti-slip limit. After the adjustment is completed, the second electric cylinder is started to drive the lower guide seat to move laterally along the slide rail 2, driving the movable seat to move to the preset position. At this time, the first electric cylinder is operated to push the active bracket to move to the left along the slide rail 1. The clamping rod applies clamping force to the right side of the part, and the flexible block is compressed synchronously to balance the pressure, thereby achieving precise clamping of the appliance parts.
