Description

Field of technology and

This utility model relates to a detachable jaw gripper, which will find application in the medical, machine-building and military industries, and in particular for fastening small parts in the production of assemblies.

BACKGROUND OF THE INVENTION

Part fastening systems are used where it is necessary for the products and / or their component parts and assemblies to be adequately fastened. The system for fastening, planning and production management is made to ensure the tracking of the details, as well as the reduction of the auxiliary time. Every detail is fixed at the beginning of the production process. With the fastening, a precisely defined and safe connection is achieved between the workpiece and the machine table, as well as between the workpiece and the respective tool. The fasteners of the systems must also absorb the forces generated during machining. The elements of the systems that securely hold the workpieces locked in place are called fasteners such as clamps or grippers. Fasteners should have a relatively simple construction, allowing quick and easy installation, as well as the possibility to be easily adapted to a new fastening. There is a need for a gripper whose jaws can be used and rotated 180 ° to grip several parts simultaneously, so-called combination grippers, in which case their jaws must be provided with the appropriate number of identical holes or ellipses.

In different fields of technology it is necessary to create different constructions of gripping devices. The need arises from the presence of many specialized environments, such as pharmaceutical, food and others, in which the drive has to be rotated around the part. Such requirements may also exist in explosive industries.

Technical essence of the utility model

The task of the utility model is to create a gripper with movable jaws, which provides separate and remote attachment of a wide range of various details, realized at extremely low operating costs.

The problem is solved by creating a gripper with movable jaws, which includes a housing to which two bases are attached opposite each other. An auxiliary surface is formed on each base. At the lower end of each base, a movable jaw provided with a spring is movably gripped in a respective center of rotation.

The advantage of the created gripper with movable jaws is the reduced risk of errors in positioning of the processed details, at the same time improvement of the accuracy in the processing of various types of parts with rotationally symmetrical parts is provided. Another advantage is that very large fastening forces are generated, leading to high machining accuracy as well as the installation of various joints.

In addition, the created gripper provides rotational fastening of the gripping jaws, which makes it suitable for use in the pharmaceutical, medical, military industry and others where gripping in a clean environment is required. The gripper has low operating costs and increased efficiency, which leads to reduced cost of the processed product and high production efficiency. It is made of standardized components, which further reduces its cost.

Examples of implementation of the utility model

The created grip with movable jaws, shown in figure 1, includes a housing 1, on which opposite to each other are attached two bases 2. On each base 2 is formed an auxiliary surface 5 formed in the process of modeling its complex structural inner surface and assisting for its stability. At the lower end of each base 2 in a corresponding mathematically defined center of rotation 4 is movably gripped a movable jaw 3 provided with a spring 6.

The use of the created gripper with movable jaws is carried out as follows.

The part 7 is fixed in the movable jaws 3 by means of the fastening center 4 and the auxiliary surfaces 5. The springs 6 help the gripper not to drop the part 7. The movable jaws 3 serve to limit the movement of the part 7 in height, providing a large contact surface between them. The pressing force is also increased so that the gripper can withstand greater dynamic and static forces. The larger contact surface between the jaws 3 and the part 7 helps to increase the speed of its movement, which in turn leads to a reduction in the auxiliary processing time of the part 7, and hence to an increase in the cost of the final product.

While closing the movable jaws 3 of the gripper, they contact the part 7 and lift it from the V-channel in which it is placed, therefore there is no need to provide a device with lifting motion. This is a prerequisite for the jaws 3 to have a suitable smooth surface. This gripper design eliminates the need for an additional movable axle.

The method of fastening the workpieces is of particular importance for performing relevant operations on them. With the fastening, a precisely defined and safe connection is achieved between the workpiece and the machine table, and hence between the workpiece and the respective tool.

The detachable jaw gripper uses standard components, which allows both reducing its cost and increasing its efficiency. It allows the attachment of various and numerous details, reducing the cost of the product, as well as high efficiency in production. This type of fastening guarantees durability, detail and speed. The gripper can work in a wide range of materials in various industries, namely cast iron, aluminum, plastic and others.
