Background

In industrial production, tool clamps are widely used for clamping and fixing workpieces to ensure stability and precision of the workpieces during processing. However, conventional tool clamps suffer from several disadvantages:

cannot sense clamping force in real time: conventional tool clamps generally lack an inductive force feedback mechanism, and cannot sense the force applied by the clamping contact piece to the workpiece in real time. This results in a failure to adjust the clamping force in time to accommodate new demands as the workpiece size, shape or material changes, possibly resulting in movement, deformation or damage to the workpiece.

Lack of tuning and optimization capabilities: traditional frock clamp generally needs manual regulation clamping-force degree, and accommodation is limited. This makes it necessary for a worker to spend a great deal of time and effort to manually adjust the clamping force, and is prone to human error. In addition, due to the lack of adjustment and optimization capabilities, the tool clamp cannot be adjusted adaptively according to the actual requirements of the workpiece, so that the clamping force is inaccurate or unstable.

The control precision is limited: the control precision of the traditional tool clamp is limited, and the requirement of precision machining cannot be met. Because of the lack of real-time feedback and accurate control mechanisms, the tool clamp cannot provide highly accurate clamping force, and workpieces often face machining errors and unstable clamping states, so that the quality and production efficiency of products are affected.

Therefore, the present disclosure provides a fixture with inductive force feedback to solve the above-mentioned problems.

All other embodiments, based on the embodiments of the utility model, which would be apparent to one of ordinary skill in the art without inventive effort are within the scope of the utility model.

It should be noted that, in the embodiment of the present utility model, directional indications (such as up, down, left, right, front, and rear … …) are referred to, and the directional indications are merely used to explain the relative positional relationship, movement conditions, and the like between the components in a specific posture (as shown in the drawings), and if the specific posture is changed, the directional indications are correspondingly changed.

In addition, "a plurality of" means two or more. In addition, the technical solutions of the embodiments may be combined with each other, but it is necessary to base that the technical solutions can be realized by those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should be considered to be absent and not within the scope of protection claimed by the utility model.

Referring to fig. 1-7 of the specification, the utility model provides a fixture with inductive force feedback, wherein a fixture table 1 of the fixture adopts a firm structure and has high bearing capacity and stability. The center of the top of the clamping driving mechanism is transversely provided with a clamping driving groove 2, so that the accurate positioning of the clamping driving mechanism is ensured, and a driving force transmission channel is provided.

The clamping driving mechanism 3 is one of key components of the tool clamp. It comprises a double-shaft speed reducing motor 31, a clamping driving screw rod 32 and a threaded sleeve block 33. The biaxial speed reducing motor 31 is installed at a central position inside the grip driving groove 2 to provide a driving force source. The clamping driving screw rod 32 is rotatably arranged at the left end and the right end of the clamping driving groove 2 and is connected with the clamping assembly 4 through a threaded sleeve block 33, so that the transmission of clamping force is realized.

The clamping contact 41 of the clamping assembly 4 is a component that is in direct contact with the workpiece to be clamped. The clamping contacts 41 are distributed in parallel on the inner side of the mounting plate 43, ensuring stable clamping of the clamping workpiece. The limiting pin 42 is mounted on the outer corner end of the clamping contact 41, and is fixed on the mounting plate 43 through a limiting through hole 431. These limit pins 42 can limit the movement range of the clamping contact 41, and ensure the accuracy of the position of the clamping workpiece.

A spring positioning cylinder 44 is located in the center of the mounting plate 43 and serves to support and position the clamping contact 41. The jack spring 45 is installed inside the spring positioning cylinder 44 to provide a jack force acting on the clamping contact, ensuring a stable clamping force.

The clamping force adjustment mechanism 46 is a key component for adjusting the clamping force. It includes a gear motor 461, a drive screw 462 and a spring loaded slider 463. The gear motor 461 is mounted at one end of the outer side of the spring positioning cylinder 44 and is connected with the spring tightening slider 463 through the driving screw 462. By starting the gear motor 461, the driving screw 462 can be driven to rotate, and then the spring pushing slider 463 is driven to push forward, so that the compression state of the pushing spring 45 can be adjusted, and the pushing force to the clamping contact 41 can be adjusted.

The guide assembly 47 is used to guide and position the movement of the clamping assembly. It includes an L-shaped arm 471 and a guide tooth 472. The L-shaped supporting arm 471 is fixed on the side surface of the mounting plate 43, and the guide teeth 472 are arranged on the inner side surface of the L-shaped supporting arm 471 and meshed with the guide grooves 11 arranged on the side edge of the tool table 1 to play a role in guiding.

The working principle is as follows:

The clamping force adjusting mechanism 46 inside the clamping assembly 4 is started, and the driving screw rod 462 can be driven to rotate by starting the gear motor 461, so that the spring jacking sliding block 463 is driven to jack forward, the compression state of the jacking spring 45 is adjusted, and the jacking force of the clamping contact 41 is adjusted.

When the gear motor 461 is started, the rotational force output therefrom is transmitted to the spring pressing slider 463 through the driving screw 462. The drive screw 462 has a threaded configuration that engages a threaded hole in the spring puller slide 463. When the driving screw 462 is rotated, the spring-loaded slider 463 is urged by the driving force to move forward in the direction of the driving screw 462.

Since the spring jack slider 463 is connected with the jack spring 45, its forward jacking movement results in compression of the jack spring. The degree of compression of the spring determines the amount of jacking force exerted by the jack spring against the clamping contact 41. When the jack spring 45 receives a larger compression force, the jack force of the clamp contact 41 increases, thereby achieving a tighter clamp.
