Description

Technical Field

[0001] The utility model relates to the technical field of automation equipment, in particular to a free-pitch variable module. Background Art

[0002] Modular design is a key trend in modern industrial design, aiming to improve design efficiency and product quality while reducing costs and risks. As a key technology in modular design, variable pitch modules offer a high degree of flexibility and intelligence.

[0003] Most of the variable pitch modules currently on the market are camshaft variable pitch modules, whose principle is to achieve equal pitch variation based on the rotation of the camshaft. However, the variable pitch movement of the related components is driven by the rotation of the camshaft. The driven related components can only operate at the same time, and the free movement of a single related component is impossible. When only a single related component is required to operate, it can only drive all the related components, resulting in unnecessary energy consumption.

[0004] Based on the above reasons, it is necessary to improve the existing technology. Utility Model Content

[0019] Figure 2 It is a partial structural diagram of the utility model.

[0020] Figure 3 It is a structural schematic diagram of the driving device of the utility model.

[0021] In the figure: 1 is a machine base, 10 is a guide rail, 11 is a wiring screw, 12 is a position sensor, 2 is a screw, 3 is a driving device, 30 is a nut, 31 is a driving motor, 32 is an electric wire, 4 is a slide seat, 40 is a slider, and 41 is a sensor bar. DETAILED DESCRIPTION

[0022] The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0023] See also Figure 1-3 , the utility model provides a free pitch variable module, including a base 1;

[0024] A screw rod 2, wherein the screw rod 2 is fixedly installed in the inner cavity of the machine base 1, and at least one screw rod 2 is provided;

[0025] A driving device 3, comprising a nut 30 sleeved on the screw rod 2 and a driving motor 31 disposed on one side of the nut 30, the driving motor 31 being configured to drive the nut 30 to perform linear reciprocating motion on the screw rod 2;

[0026] The slide 4 is fixedly arranged on the top of the driving device 3.

[0027] In the above structure, the operator only needs to control the drive motor to rotate the nut controlled by the drive motor, so that the power of the nut rotation is converted into a linear reciprocating motion of the entire drive device on the screw through the cooperation of the nut and the screw. By only starting the drive motor at the bottom of the corresponding slide, the movement of the slide can be freely controlled to achieve free pitch change.

[0028] Specifically, guide rails 10 are symmetrically provided on both sides of the machine base 1, and sliders 40 are provided at both ends of the slide seat 4 for use with the guide rails 10. The cooperation of the guide rails and the sliders is used to play a guiding role. At the same time, the cooperation of the guide rails and the sliders can help the screw rod share the downward pressure applied to the screw rod by the entire drive device.

[0029] Specifically, three screw rods 2 are arranged horizontally, multiple slides 4 are arranged in the direction of the guide rail 10, and the driving device 3 fixed at the bottom is staggered on the three screw rods 2. The use of multiple screw rods can prevent more driving devices and the slides thereon from being staggered, thereby increasing the number of slides that can be used on the entire free pitch module.

[0030] Specifically, a plurality of position sensors 12 are staggeredly arranged on the side of the machine base 1, and a plurality of the slides 4 are provided with induction strips 41 used in conjunction with the position sensors 12. The use of the induction strips and the position sensors can help each slide return to the basic position, effectively avoiding the situation where the slide position cannot be reset to zero after the free pitch module is restarted due to sudden reasons such as power outages.

[0031] Specifically, the base 1 is rotatably provided with a wiring screw 11 on both sides, and the wiring screw 11 is used to accommodate the wires 32 of the drive motor 31. Using the wiring screw to place and store the wires of the drive motor can effectively prevent the drive motor from being unable to operate due to the entanglement of multiple wires when there are too many drive motors.

[0032] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
