Description

Technical Field

[0001] The utility model relates to the technical field of digital control multi-way valves, in particular to an electric push rod type digital control multi-way valve. Background Art

[0002] CNC multi-way valve is a key component widely used in CNC hydraulic systems. It is mainly used to control the actions of multiple actuators and realize complex industrial automation control functions. The multi-way valve is composed of valve body, valve core, spring, valve seat, sealing ring and other components. The hydraulic oil flows from the inlet and flows to different outlets through the control of the valve core to realize the hydraulic action. There are two main types of multi-way valve working principles: flow distribution type multi-way valve and flow regulation type multi-way valve. In the former, when the control quantity changes, the multi-way valve will automatically adjust its outlet flow, while in the latter, when the outlet flow changes, the multi-way valve will automatically adjust the control quantity. This adjustment mechanism enables the multi-way valve to achieve precise control of the hydraulic system. In CNC hydraulic systems, the application scenarios of the multi-way valve are very wide. It can be used for fluid control and distribution of industrial robots, forging machines, injection molding machines and other equipment to improve production efficiency and product quality. In the fields of agricultural machinery, construction engineering, engineering machinery, etc., multi-way valves also play an important role to achieve precise control and motion control of equipment.

[0003] At present, the opening and closing of CNC multi-way valves are generally achieved by manual push rods, which require manual push and pull operations, which is very inconvenient and requires occupying part of the space in the operating chamber to achieve the forward and backward push and pull operations of the push rods.

[0004] Therefore, an electric push rod type numerically controlled multi-way valve is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the utility model will be clearly and completely described 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 of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Example:

[0027] See also Figure 1-4The present embodiment provides an electric push rod type numerical control multi-way valve, comprising a multi-way valve 1, a support seat 2 is symmetrically installed at both ends of one side of the multi-way valve 1, a vertical plate 3 is installed at one end of the top of the support seat 2, an electric push rod 4 is installed at the top of the inner side of the vertical plate 3, a rubber sleeve 10 is installed at the other end of the top of the support seat 2, a push rod 11 is installed on the top of the rubber sleeve 10, a telescopic rod 13 is connected to the top of the push rod 11, a connecting block 15 is fixedly connected to the top of the telescopic rod 13, a groove 151 is opened at the top of the connecting block 15, a rotating rod 16 is connected between the inner sides of the groove 151, and the rotating rod 16 is rotatably connected to one end of the electric push rod 4. When the push rod needs to be pushed forward, 11, the electric push rod 4 is started to extend. At this time, one end of the electric push rod 4 pushes the connecting block 15 to tilt forward. At the same time, the connecting block 15 drives the push rod 11 to tilt forward through the telescopic rod 13, thereby pushing the push rod 11 forward. When it is necessary to pull the push rod 11 back, the electric push rod 4 is started to shorten, so that one end of the electric push rod 4 pulls the connecting block 15 to tilt backward. At the same time, the connecting block 15 drives the push rod 11 to tilt backward through the telescopic rod 13, thereby realizing the backward pulling operation of the push rod 11. Since the forward and backward pushing and pulling of the push rod 11 can be completed by the extension and retraction of the electric push rod 4, there is no need to push the push rod manually, thereby effectively solving the problem that the current multi-way valve opening and closing requires manual pushing and pulling of the push rod.

[0028] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, one end of the electric push rod 4 is fixedly connected to a pull rod 5, and a through hole 501 is opened between the two side surfaces of one end of the pull rod 5. One end of the pull rod 5 extends into the inner side of the groove 151 and is rotatably sleeved on the outer ring surface of the rotating rod 16 through the through hole 501. There is a gap of a certain distance between the bottom of the pull rod 5 and the bottom of the inner side surface of the groove 151. By utilizing the rotational connection between the pull rod 5 and the connecting block 15, the pull rod 5 can push the connecting block 15 forward without causing motion interference.

[0029] In this embodiment, if Figure 1 and Figure 4 As shown, the top of the handle 8 is spherical, and buttons 9 are symmetrically installed on both sides of the handle 8. The buttons 9 are electrically connected to the electric push rod 4. One button 9 on the handle 8 can control the extension of the electric push rod 4, and the other button 9 can control the shortening of the electric push rod 4. At this time, hold the handle 8 by hand, and control the extension and retraction operation of the electric push rod 4 by pressing the two buttons 9 on the handle 8, and enter the push-pull operation of the control push rod 11.

[0030] In this embodiment, if Figure 1 and Figure 2As shown, the inner side of the push rod 11 is hollowed out, one end of the telescopic rod 13 extends into the inner side of the push rod 11 and is slidably connected to the push rod 11, a baffle 14 is fixedly installed at the bottom of the telescopic rod 13, and the top of the baffle 14 is the same size as the inner top of the push rod 11, thereby preventing the telescopic rod 13 from separating from the push rod 11 when sliding inside the push rod 11.

[0031] In this embodiment, if Figure 1 and Figure 2 As shown, a spring 12 is sleeved and installed on the outer ring surface of the telescopic rod 13, and the top and bottom of the spring 12 are respectively fixedly connected to the bottom of the connecting block 15 and the top of the push rod 11. In the initial state, the spring 12 pulls down the connecting block 15 to make part of the length of the telescopic rod 13 slide into the inner side of the push rod 11, so that when the electric push rod 4 pushes the connecting block 15 through the pull rod 5, the telescopic rod 13 can be extended to make up for the distance requirement between the connecting block 15 and the push rod 11 after tilting, thereby avoiding motion interference.

[0032] In this embodiment, if Figure 1 , Figure 2 and Figure 3 As shown, the two inner side surfaces of the groove 151 fit with the two side surfaces of the pull rod 5, and the outer annular surface of the rotating rod 16 fits with the inner wall of the through hole 501, so that the rotation between the pull rod 5 and the rotating rod 16 is more stable.

[0033] Working principle: When the CNC multi-way valve is in use, when it is necessary to push the push rod 11 forward, manually press the button 9 on the handle 8 that controls the extension of the electric push rod 4. At this time, one end of the electric push rod 4 pushes the connecting block 15 forward, driving the pull rod 5 to push the connecting block 15 forward, and the connecting block 15 drives the push rod 11 forward through the telescopic rod 13 during the forward tilting process, so as to push the push rod 11 forward. When it is necessary to pull the push rod 11 backward, manually press the button 9 on the handle 8 that controls the shortening of the electric push rod 4, and the electric push rod 4 shortens, so that one end of the pull rod 5 is pulled back. The movable connecting block 15 tilts backward, and at the same time, the connecting block 15 drives the push rod 11 to tilt backward through the telescopic rod 13, so as to realize the backward pulling operation of the push rod 11. When the electric push rod 4 pushes the connecting block 15 through the pull rod 5, the telescopic rod 13 can be extended to make up for the distance requirement between the connecting block 15 and the push rod 11 after the tilt, thereby avoiding motion interference. At the same time, since the forward and backward pushing and pulling of the push rod 11 can be completed by the extension and retraction of the electric push rod 4, there is no need to push the push rod manually, thereby effectively solving the problem that the current multi-way valve opening and closing requires manual forward and backward pushing and pulling of the push rod.

[0034] All technical features in this embodiment can be freely combined according to actual needs.

[0035] The above embodiments are preferred implementation schemes of the present invention. In addition, the present invention can also be implemented in other ways. Any obvious replacement without departing from the concept of the present technical solution is within the protection scope of the present invention.
