Description

Technical Field

[0001] This utility model belongs to the field of glass edging machine equipment, and particularly relates to a servo-controlled manual / automatic grinding head feeding system with linear guide rail. Background Technology

[0002] Glass edging machines mainly use grinding heads to perform glass processing steps. This requires a feeding system for the grinding head to perform the glass processing work. Existing feeding systems are usually automated feeding systems driven by electric motors. Although this eliminates the need for frequent manual operation to adjust the feed amount, when there is a need to temporarily adjust the feed amount or adjust the origin of the feeding system, the parameters can only be adjusted on the operating system, which is inconvenient.

[0003] This invention designs a servo-controlled, manual / automatic grinding head feed system with linear guide rails to solve the above problems. Utility Model Content

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A servo-controlled, manual / automatic grinding head feed system with linear guide rails includes an upper support plate, a lower support plate, and a lead screw bearing housing. The upper support plate is slidably mounted on the upper end of the lower support plate. The lead screw bearing housing is mounted on one end of the upper support plate. A lead screw nut housing is mounted on the upper end of the lower support plate. A lead screw is mounted on the lead screw bearing housing. The front end of the lead screw is connected to the lead screw nut housing, and a transmission gear is mounted on the rear end of the lead screw. A first gear shaft and a second gear shaft, located on both sides of the transmission gear, are rotatably connected on the lead screw bearing housing. Both the first and second gear shafts mesh with the transmission gear. A motor that is poweredly connected to the first gear shaft is mounted on the lead screw bearing housing. The outer end of the second gear shaft extends to the outside of the lead screw bearing housing and is fitted with a handle.

[0006] As a preferred embodiment, the upper part of the lower support plate is equipped with two parallel guide rails, which are located on both sides of the lead screw. Slider blocks are installed on the guide rails, and the upper support plate is installed on the two slider blocks.

[0007] As a preferred embodiment, the lead screw is connected to the lead screw bearing housing via an angular contact ball bearing.

[0008] As a preferred embodiment, the second gear shaft is connected to the lead screw bearing housing via two thrust ball bearings, and a locking nut is installed on the second gear shaft, with the locking nut tightly attached to the outer wall of the thrust ball bearing located on the side away from the transmission gear.

[0009] As a preferred embodiment, a position indicator for displaying the position of the grinding head is mounted on the second gear shaft, and the position indicator is located outside the lead screw bearing housing.

[0010] As a preferred option, the transmission gear is a reduction gear.

[0011] As a preferred embodiment, the speed ratio between the transmission gear and the first gear shaft is 4:1.

[0012] As a preferred embodiment, the speed ratio between the transmission gear and the second gear shaft is 2:1.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. With the cooperation of the lead screw nut seat, transmission gear, first gear shaft and second gear shaft, the motor and handle can control the upper support plate to move on the lower support plate. The position of the grinding head is adjusted by the movement of the upper support plate. The grinding head position adjustment function is integrated with manual and automatic functions. The automatic adjustment function has the advantages of high precision and no need for personnel supervision, while the manual adjustment function can meet the needs of quick temporary adjustment.

[0015] 2. The transmission ratio between the transmission gear and the first gear shaft of this utility model can effectively reduce the rated torque of the motor, thereby achieving energy saving and emission reduction.

[0016] 3. The second gear shaft of this utility model is fixed by two thrust ball bearings, which solves the problem of installation gap in the second gear shaft. Attached Figure Description
