Description

Technical Field

[0001] This utility model relates to the field of lens processing equipment, and in particular to an adaptive gravity balance guide rail structure. Background Technology

[0002] Lens processing equipment typically includes a guide rail structure, which primarily drives the spindle. Existing guide rail structures are mainly of two types: vertical and horizontal. Horizontal guide rail structures are simpler, while vertical guide rail structures require balancing the spindle's weight to ensure the stability of the lens processing equipment and the machining accuracy. Therefore, a guide rail structure that can adaptively maintain spindle weight balance is needed. Utility Model Content

[0003] The purpose of this invention is to solve at least one of the technical problems existing in the prior art and to provide an adaptive gravity balance guide rail structure.

[0004] The adaptive gravity balance guide rail structure according to an embodiment of the present invention includes a base and a platform. The base is provided with a vertical guide rail, a balance cylinder, an air tank, a detection device, and a control device. The platform is provided with a main shaft and a drive mechanism. The drive mechanism can drive the platform to move up and down along the guide rail. The balance cylinder is located at the top of the guide rail. The balance cylinder includes a cylinder barrel, a piston, and a piston rod connected to the piston. The piston rod is connected to the platform. The piston divides the cylinder barrel into upper and lower layers. The air tank is connected to both ends of the cylinder barrel. The detection device can detect the pressure of the upper and lower layers in the cylinder barrel. The control device controls the air tank to fill the upper or lower layer of the cylinder barrel with gas according to the pressure difference between the upper and lower layers, so that the main shaft remains balanced.

[0005] The adaptive gravity balance guide rail structure according to this utility model embodiment has at least the following beneficial effects: When the drive mechanism drives the main shaft to move upward, the piston squeezes upward in the cylinder, increasing the pressure in the upper layer and decreasing the pressure in the lower layer, causing a change in the pressure difference between the upper and lower layers, making it impossible to balance the gravity of the main shaft; at this time, the detection device detects the pressure in the upper and lower layers of the cylinder and feeds the pressure information back to the control device. The control device can calculate the pressure difference between the upper and lower layers, and the control device has a pre-set target pressure difference that can balance the main shaft. By comparing the current pressure difference with the target pressure difference, the control device controls the gas tank to fill a certain amount of gas into the corresponding upper or lower layer of the cylinder, so that the detected pressure difference is consistent with the target pressure difference. In this way, adaptive gravity balance adjustment can be achieved, with a simple structure and easy application.

[0006] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0014] Reference Figures 1 to 3This utility model discloses an adaptive gravity balance guide rail 11 structure, comprising: a base 10 and a base 20. The base 10 is provided with a vertical guide rail 11, a balance cylinder, an air tank 12, a detection device 13, and a control device. The base 20 is provided with a main shaft 21 and a drive mechanism, which can drive the base 20 to move up and down along the guide rail 11. The balance cylinder is located at the top of the guide rail 11 and includes a cylinder 31, a piston 32, and a piston rod 33 connected to the piston 32. The piston rod 33 is connected to the base 20. The piston 32 divides the cylinder 31 into upper and lower layers. The air tank 12 is connected to both ends of the cylinder 31. The detection device 13 can detect the pressure in the upper and lower layers of the cylinder 31. The detection device 13 can be a pressure sensor, which can be located in the upper and lower layers of the cylinder 31 or can detect the pressure in the upper and lower layers of the cylinder 31 through an air pipe. The control device controls the gas storage tank 12 to fill the upper or lower layer of the cylinder 31 with gas based on the pressure difference between the upper and lower layers, thus maintaining the balance of the main shaft 21. When the drive mechanism drives the main shaft 21 to move upward, the piston 32 squeezes upward within the cylinder 31, increasing the pressure in the upper layer and decreasing the pressure in the lower layer, causing a change in the pressure difference between the two layers, which makes it impossible to balance the gravity of the main shaft 21. At this time, the detection device 13 detects the pressure between the upper and lower layers in the cylinder 31 and feeds the pressure information back to the control device. The control device can calculate the pressure difference between the upper and lower layers, and the control device has a pre-set target pressure difference to balance the main shaft 21. By comparing the current pressure difference with the target pressure difference, the control device controls the gas storage tank 12 to fill a certain amount of gas into the corresponding upper or lower layer of the cylinder 31, so that the detected pressure difference matches the target pressure difference. This achieves adaptive gravity balance adjustment, with a simple structure and easy application.

[0015] In some embodiments, the guide rail 11 is a magnetic rail, and the driving mechanism is a linear motor, which drives the base 20 to rise and fall through the action of electromagnetic force. The linear motor has the advantages of high precision, high speed, high efficiency and simple structure.

[0016] Furthermore, it also includes two inflation pipes connected to the gas storage tank 12. The top of the base 10 is provided with an installation box 14 for installing the gas storage tank 12. The installation box 14 has a through hole 15 for passing through the inflation pipes. The two inflation pipes are respectively connected to the upper and lower ends of the cylinder 31 to facilitate inflation to the upper or lower layer of the cylinder 31.

[0017] Furthermore, the inflation pipe is equipped with a solenoid valve that is electrically connected to the control device. The control device controls the opening and closing of the corresponding solenoid valve by detecting the pressure difference, so as to inject gas into the upper or lower layer of the cylinder 31.

[0018] Furthermore, it also includes a connecting block 34 connected to the piston rod 33. The upper end surface of the base 20 is provided with a groove 22 that can cooperate with the connecting block 34. The connecting block 34 is connected to the bottom of the groove 22 by a connector 35 (bolt or screw). The structure is simple and facilitates the connection between the balance cylinder and the base 20.

[0019] It will be readily understood by those skilled in the art that the above preferred methods can be freely combined and superimposed without conflict.

[0020] The above are merely preferred embodiments of this utility model and do not limit the patent scope of this utility model. Any equivalent structural transformations made based on the inventive concept of this utility model and the contents of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are included within the patent protection scope of this utility model.
