Detailed Description

The following detailed description of embodiments of the invention is, therefore, to be taken in conjunction with the accompanying drawings, and it is to be understood that the scope of the invention is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the term "comprise" or variations thereof such as "comprises" or "comprising", etc. will be understood to include the stated element or component without excluding other elements or other components.

The clamping and positioning device provided by the invention is generated based on analysis of the defects of the clamping and positioning jig in the existing manufacturing process. Specifically, in the existing planar product manufacturing process, such as laser engraving, laser welding of studs, etc., special clamping and positioning jigs are generally required to ensure accuracy and efficiency. However, each specification of product often requires a specific jig, which not only increases the complexity of jig production and management, but also wastes a large amount of production resources. In addition, due to the single positioning performance of the jig, the jig cannot be suitable for rapid debugging of the position degree of various types of products in the processes of laser welding and the like, and a great deal of time and labor are consumed in the debugging process, so that the time cost is wasted.

Based on the problems, the inventor provides the invention, and the core idea is to design a multifunctional clamping and positioning device which can realize clamping and positioning, rapid debugging and accurate welding of stud samples with various types and specifications. Through improving the structure and the function of the device, the device has the capabilities of clamping and quick positioning in multiple specifications, so that the device is suitable for high-efficiency manufacturing of stud samples in different types and specifications, can greatly improve the debugging efficiency of various planar products, reduces the debugging time, and simultaneously increases the manufacturing precision and stability.

Referring to fig. 1 to 9, a clamping and positioning device according to an embodiment of the invention includes a base 1, a carrying mechanism 2, a transferring mechanism 3 and a clamping mechanism 4. The carrying mechanism 2 is disposed on the base 1, and the carrying mechanism 2 has a carrying table 21 for carrying products. The transfer mechanism 3 is provided on the base 1, and the movement range of the transfer mechanism 3 covers the area where the carrying table 21 is located. The clamping mechanism 4 is arranged on the transfer mechanism 3, the clamping mechanism 4 can be driven by the transfer mechanism 3 to move to the bearing table 21, the clamping mechanism 4 comprises a rotary disc 41 and a plurality of clamping pieces 42 movably arranged on the rotary disc 41, and the rotary disc 41 can move the clamping pieces 42 to zoom and retract a clamping space 43 surrounded by the clamping pieces 42.

According to the clamping and positioning device provided by the embodiment, products can be effectively supported and stabilized through the design of the bearing mechanism 2, the clamping mechanism 4 is arranged on the transferring mechanism 3, and can be moved to the bearing table 21 under the driving of the transferring mechanism 3, so that products of different types and specifications can be processed under the condition that the jig is not replaced, the working efficiency is greatly improved, the area where the bearing table 21 is located is covered by the transferring mechanism 3, the clamping mechanism 4 can flexibly move in the device, the clamping mechanism 4 comprises the rotating disc 41 and a plurality of clamping pieces 42, the size of the clamping space 43 can be adjusted by rotating the rotating disc 41, and the adaptability and the flexibility of the clamping mechanism 4 are enhanced.

The clamping and positioning device is designed to reflect the versatility of the device. For example, for stud samples with different specifications, only the rotating disc 41 of the clamping mechanism 4 needs to be adjusted, so that the size of the clamping space 43 is adapted to the specifications of the samples, and meanwhile, quick debugging and accurate welding can be realized through the transfer mechanism 3, thereby avoiding time and resource waste caused by using a single positioning jig and improving the production efficiency.

In an exemplary embodiment, referring to fig. 1 and 2, the carrying mechanism 2 includes a plurality of clamping blocks 22, a plurality of spiral sliding grooves 23 corresponding to the clamping blocks 22 one by one are provided on the carrying platform 21, the clamping blocks 22 are slidably provided on the spiral sliding grooves 23, a positioning space is defined between the plurality of clamping blocks 22, and rotating the carrying platform 21 can move the clamping blocks 22 along the radial direction of the spiral sliding grooves 23 to zoom the positioning space. The combination design of the plurality of clamping blocks 22 and the spiral chute 23 enables the clamping blocks 22 to move towards the radial direction of the chute, so that the size of the positioning space is adjusted. For example, when a product having a large size needs to be processed, the carrying table 21 may be rotated to move the clamping block 22 outwardly with respect to the center of the spiral chute 23, thereby enlarging the size of the positioning space; conversely, when a product with a smaller diameter is processed, the carrying table 21 can be reversely rotated to move the clamping block 22 inwards relative to the center of the spiral chute 23, thereby reducing the size of the positioning space. Preferably, the number of the clamping blocks 22 and the spiral type sliding grooves 23 is four, the centers of the spiral type sliding grooves 23 are coincident, the distances from the clamping blocks 22 to the centers of the spiral type sliding grooves 23 are equal, and the four clamping blocks 22 are arranged in a square shape.

Specifically, the carrying mechanism 2 further includes a bracket 24 mounted on the base 1, the carrying platform 21 is rotatably disposed on the bracket 24, the mounting seat 44 is provided with a plurality of limit rails 25 extending along a radial direction of the spiral chute 23, and the clamping blocks 22 are slidably mounted on the limit rails 25. Through the setting of spacing track 25, it only can follow the radial movement of spiral spout 23 to have limited grip block 22, and when rotatory plummer 21, spiral spout 23 can produce thrust to grip block 22 to promote grip block 22 along the radial movement of spiral spout 23, thereby change the location space size, in order to fix the product of different specification sizes. Moreover, due to the existence of the bracket 24, the bearing table 21 can stably rotate, and displacement or rolling caused by overweight or other factors of the bearing sample can not be caused, so that the stable operation and the manufacturing precision of the equipment are ensured.

In a specific example, if a large-sized product is to be fixed, the carrying table 21 may be rotated so that the clamping blocks 22 slide outward along the limit rails 25, thereby enlarging the size of the positioning space. Conversely, if a small-sized product is to be secured, the carrier 21 can be rotated in the opposite direction so that the clamp block 22 slides inwardly along the limit rail 25, thereby reducing the size of the positioning space. The design effectively realizes the quick adjustment of the size of the positioning space, and greatly improves the working efficiency.

In some embodiments, it is contemplated that the shape and configuration of the bracket 24 may be varied to accommodate different work environments and requirements. For example, the height-adjustable brackets 24 may be designed to accommodate operating requirements of different heights. It is contemplated that differently shaped stop rails 25, such as linear, curvilinear, etc., may be used to accommodate different movement requirements. The carrier 21 may be designed in different shapes and configurations to accommodate different sizes and shapes of products. For example, the angle-adjustable carrying platform 21 can be designed to adapt to the operation requirements of different angles.

Further, the clamping block 22 is provided with a limiting portion 26, and the limiting portion 26 includes a supporting surface 261 for supporting a product and an abutting surface 262 for limiting the product. The stop 26 includes a support surface for supporting the product and an abutment surface 262 for defining the product, which allows for a more stable placement and positioning of the product. By way of specific example, assuming a rectangular product is to be held, one can place the product on the support surface 261 and the abutment surface 262 serves as a boundary to limit the position of the product and prevent the product from moving or sliding during processing. Therefore, the design can ensure the stability of the sample in the processing process, thereby improving the processing precision. A key advantage of this design is its versatility and adaptability, and the fixation of the product can be achieved as long as the sample can be placed on the support surface 261 and can be defined by the abutment surface 262, regardless of the shape and size of the product.
