Description

A new type of electromagnetic differential speed linkage device

technical field

The utility model relates to a linkage device, in particular to a different-speed linkage equipment with different linkage speeds.

Background technique

The traditional clamping mechanism, tensioning mechanism or different-speed linkage equipment with different linkage speeds often use a mechanism with a dual-drive power source, and the power source often uses a cylinder, motor, etc. Its disadvantages are that the control system is relatively complex due to the need to control the actions of two power sources at the same time, resulting in poor reliability of the linkage action of the mechanism, large equipment volume, high cost of power source procurement and use, and is not conducive to energy conservation and environmental protection.

Contents of the invention

The utility model provides a single-drive power source variable-speed linkage device with better performance, small size and low cost in view of the defects of the above-mentioned variable-speed linkage equipment with dual-drive power sources.

In order to achieve the above purpose, the solution adopted by the utility model is: a new type of electromagnetic differential speed linkage device, including a mounting frame, and a power source fixed on the mounting frame; Guide rails, from right to left are the active guide rail and the driven guide rail respectively; there are sliders on the active guide rail and the driven guide rail, which are respectively the active slider and the driven slider; the inner sides of the active slider and the driven slider are opposite to each other There are gear racks arranged in parallel, which are the driving rack and the driven rack respectively. The tooth pitches of the driving rack and the driven rack are different; there is a rotatable linkage gear between the driving rack and the driven rack. , the gear is set on the installation frame through the bearing; the driving rack and the driven rack are meshed with the linkage gear respectively; the aforementioned power source is the electromagnetic control assembly installed on the outer upper side of the installation frame, and the electromagnetic control assembly includes The iron core, armature, iron core protection buffer, coil and coil drive circuit, the static iron core, buffer block, coil and coil drive circuit are all arranged in the fixed frame; the static iron core is an "E"-shaped structure, and its open end faces The lower setting; the core protection buffer is set on the upper part of the static iron core; the coil is sleeved in the static iron core, and the coil driving circuit is electrically connected to the coil; ;The active slider is provided with a tension spring that pulls the active slider downward; the driven slider is provided with a tension spring that pulls the driven slider upward; , then extend forward again, then extend to the right after the center position of the installation frame, and then extend to the linkage crank arm below the installation frame but not in contact with the installation frame. The linked crank arm can bypass the workpiece to realize the up and down linkage.

As an illustration of the above technical solution, the tension generated by the extension spring makes the active slider and the driven slider press against each other, and the static iron core and coil of the electromagnetic control component generate an upward attractive force, which stretches the extension spring and pushes the active slider. The block and driven slider open oppositely. Only one power source is needed to push the active rack to do linear motion, the active rack drives the linkage gear to rotate, and the dynamic linkage gear drives the driven rack to also perform linkage linear motion opposite or opposite to the active rack, but due to the tooth distance between the two They are not the same, and the moving speeds of the two are also different. Therefore, the driving rack and the driven rack drive the driving slider and the driven slider to move, and different speed linkage can be realized. Because it is a single driving power source, the control is more convenient, the volume can be made smaller, the linkage of different speeds is realized through mechanical transmission, the control is more convenient, energy saving and environmental protection, production costs, maintenance and use costs are low. The speed ratio can be changed by changing the size of the tooth pitch, that is, within a unit time, the active slider and the driven slider move oppositely or oppositely, but the strokes of the two are different. Among them, the linkage function can be realized by connecting the external linkage mechanism with the active slider and the driven slider.

As an improvement of the above technical solution, the aforementioned linkage gear is composed of two coaxial gears of different sizes, wherein the large gear meshes with the driving rack, and the pinion meshes with the driven rack. Since the angular speed of the large and small gears is the same when they rotate, but the linear speed is different, the speed transmitted to the rack is also different, so different linkage speeds can be realized.

As a further illustration of the above technical solution, the aforementioned guide rail is a dovetail guide rail, and the slider is a dovetail groove slider.

As an improvement of the above technical solution, a chute is provided on the bottom side of the aforementioned rack, and a roller supporting the rack is provided in the chute, and the roller is fixed on the installation frame. The chute is matched with the roller, which can not only support the function of the rack, but also play the role of limiting the stroke of the rack.

It can be known from the above scheme that the utility model has the following advantages: scientific structure, simple and practical, stable structure, easy manufacture, small size, convenient assembly, low cost, and different speed linkage action can be realized with only one driving power source, easy Control, safe and reliable, can be widely used in clamping mechanism, tensioning mechanism or different speed linkage equipment with different linkage speeds.
