TECHNICAL FIELD

[0001] The utility model relates to mechanical clamping field especially, and it is a kind of fixed pressing jaw for auxiliary processing. BACKGROUND

[0002] In the processing industry, fixing and stabilizing the workpiece is the key to ensure the processing precision and efficiency, but the existing clamping technology has certain problems in practical application.

[0003] Firstly, the clamping jaw used in the prior art is often designed complicatedly, composed of numerous delicate components, which not only increases the manufacturing cost, but also makes the maintenance in daily use extremely difficult. The complicated structure means higher failure rate, and once failure occurs, the maintenance process is time-consuming and laborious, which seriously affects the production efficiency.

[0004] Secondly, another significant problem of the prior art is the lack of universality. Since the shapes, sizes and weights of different products are different, the traditional clamping jaw design can often only be used for clamping specific types of products. This limitation leads to the fact that processing enterprises have to frequently change the clamping device when facing diversified products, and even need to customize specific clamping equipment for each new product, which undoubtedly increases the production cost and operational complexity.

[0005] At the same time, the operation convenience of the existing clamping technology needs to be improved. The complicated clamping jaw design often accompanies with complicated operation steps, and the operator needs to be professionally trained to master it, which limits the production efficiency and flexibility of the processing enterprise to some extent.

[0006] Therefore, the existing clamping technology has obvious deficiencies in structural complexity, universality and operation convenience, and how to design a new type of fixed pressing jaw for auxiliary processing to solve the problems existing in the prior art and improve the efficiency and stability of the processing process is a problem to be solved by the technical personnel in the field. CONTENT OF THE UTILITY MODEL

[0007] The utility model aims at providing a fixed pressing jaw for auxiliary processing to solve the problem of obvious deficiency in structural complexity, universality and operation convenience of the existing clamping technology.

[0008] In order to achieve the above object, the technical scheme of the utility model is a kind of fixed pressure pawl for auxiliary processing, including telescopic mechanism and connecting rod mechanism, the connecting rod mechanism includes fixed support, rack, connecting rod, pressure arm and pressure block, the fixed support is the "concave" shape structure of setting certain angle, the fixed support below is provided with fixed bolt, the fixed support is set on processing equipment by the fixed bolt below, the fixed support upper end is fixedly connected with the main part of telescopic mechanism, two racks are provided in the middle of the fixed support, the rack is "L" shape, oppositely arranged, the vertical plate lower end of the rack is rotatably connected with the lower end of connecting rod, the vertical plate upper end of the rack is rotatably connected with the rear end of pressure arm, the upper end of connecting rod is rotatably connected with the telescopic end of telescopic mechanism, and the pressure block is arranged on the front end of pressure arm.

[0009] Further, the pressure block is cylindrical as a whole, thin at the connection with the pressure arm and thick at the lower end.

[0010] Preferably, the pressure arm is hollow in the middle to reduce the overall weight.

[0011] Preferably, the telescopic mechanism is a pneumatic cylinder.

[0012] Preferably, the telescopic mechanism is a motor.

[0013] The utility model has the advantages and beneficial effects that compared with the complex jaw design in the prior art, the fixed pressure pawl for auxiliary processing is simpler in structure, mainly composed of telescopic mechanism and connecting rod mechanism, with smaller components, effectively reducing the manufacturing cost and maintenance difficulty. Due to the unique connecting rod mechanism design, the fixed pressure pawl can adapt to products of different shapes, sizes and weights, greatly improving the versatility of the clamping equipment and reducing the cost of frequent replacement or customization of grippers due to product diversification. The hollow design in the middle of the pressure arm reduces the overall weight, which helps to reduce energy consumption during operation and improve operational agility.

[0018] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all the other embodiments obtained by the person skilled in the art without creative labor fall within the protection scope of the utility model. In addition, it should be understood that the specific embodiments described herein are only used for illustrating and explaining the utility model, rather than limiting the utility model. In the utility model, the orientation words such as 'upper' and 'lower' are generally used for indicating the upper and lower in the actual use or working state of the device, and the specific is the drawing direction in the drawings; and 'inner' and 'outer' are used for the contour of the device.

[0019] As shown in Figure 1 and Figure 2 The technical scheme of the utility model is to design a fixed pressing jaw for auxiliary machining, which comprises a telescopic mechanism 1 and a connecting rod mechanism 2.

[0020] The telescopic mechanism 1 is the core driving component of the utility model, which is responsible for providing power to make the connecting rod mechanism 2 act. It can be composed of a gas cylinder or a motor, and has the characteristics of telescopic self, and the gas cylinder is adopted in the embodiment, and the driving of the connecting rod mechanism 2 is realized by controlling the telescopic end. The telescopic mechanism 1 is located at the upper end of the fixed support 21, and the main part is tightly connected with the fixed support 21.

[0021] The connecting rod mechanism is the main driving and executing component of the utility model, which is composed of multiple components, and cooperates to complete the fixing and pressing work of the workpiece, which comprises a fixed support 21, a rack 22, a connecting rod 23, a pressing arm 24 and a pressing block 25 and the like.

[0022] The fixed support 21 is the supporting component of the connecting rod mechanism 2, which is designed as a certain angle 'concave' structure, and has sufficient strength and stability. The fixed bolt 211 is arranged below the fixed support 21, and the fixed support 21 can be stably installed on the machining equipment by rotating the fixed bolt 211. The upper end of the fixed support 21 is tightly connected with the main part of the telescopic mechanism 1, so as to ensure the effective transmission of power.

[0023] The frame 22 is an important component of the linkage mechanism 2, which adopts an "L" shape design and has sufficient rigidity and stability. The frame 22 is arranged opposite to the middle part of the fixed support 21, and a certain space is formed between the two frames 2 for accommodating the linkage 23, the pressing arm 24 and other components. The lower end of the vertical plate of the frame 2 is rotatably connected to the lower end of the linkage 23, so that the linkage 23 can rotate under the constraint of the frame 22.

[0024] The linkage 23 is responsible for transmitting the power of the telescopic mechanism 1 to the pressing arm 24. The upper end of the linkage 23 is rotatably connected to the telescopic end of the telescopic mechanism 1, so that the linkage 23 can rotate with the telescopic mechanism 1. The lower end of the linkage 23 is rotatably connected to the lower end of the vertical plate of the frame 22, forming a rotatable fulcrum.

[0025] The pressing arm 24 is an execution component of the linkage mechanism 1, which is responsible for directly contacting and applying pressure to the workpiece. The rear end of the pressing arm 24 is rotatably connected to the upper end of the vertical plate of the frame 22, so that the pressing arm 24 can rotate under the constraint of the frame 22. In order to reduce the overall weight and improve the agility of operation, the middle part of the pressing arm 24 in this embodiment adopts a hollow design.

[0026] The pressing block 25 is a component fixed to the front end of the pressing arm 24, which is responsible for directly contacting and applying pressure to the workpiece. The pressing block 25 is designed in a cylindrical shape, with a thinner connection part at the upper part and a thicker working part at the lower end, to ensure that the contact area with the workpiece is large enough and the applied pressure is evenly distributed.

[0027] Specific working mode:

[0028] In actual application, the operator first places the workpiece to be processed in the working area of the fixed pressing jaw. Then, the telescopic mechanism 1 is controlled to make the telescopic end perform telescopic movement. This action is transmitted to the pressing arm 24 through the linkage 23, causing the pressing arm 24 and the pressing block 25 to produce corresponding actions, thereby firmly pressing the workpiece. Due to the unique design of the linkage mechanism 2, the fixed pressing jaw can adapt to and firmly press workpieces of different shapes, sizes and weights, greatly enhancing the versatility and flexibility of the clamping device. During processing, the fixed pressing jaw can ensure the stability and processing accuracy of the workpiece, thereby improving the overall processing efficiency. After processing is completed, the pressing arm 24 and the pressing block 25 are released by the telescopic mechanism 1 to release the workpiece, facilitating the next operation of the operator.

[0029] The above has carried out the detailed introduction to the fixed pressing claw for auxiliary machining provided by the utility model. The principle and implementation mode of the present application are described by applying specific examples in this paper, and the above embodiment description is only used to help understand the method and core idea of the utility model. It should be pointed out that, for ordinary skilled persons in the technical field, some improvements and modifications can be made to the present application without departing from the principle of the present application, and these improvements and modifications also fall within the protection scope of the utility model claim.
