Description

Technical Field

[0001] The utility model relates to the technical field of bench-type drilling machines, in particular to a bench-type drilling machine with a double-guiding mechanism. Background Art

[0002] A drilling machine is a machine tool that primarily uses a drill to create holes in a workpiece. Typically, the drill's primary motion is rotation, with axial movement serving as the feed motion. Drilling machines have a simple structure and relatively low machining accuracy. They can drill through holes, blind holes, and, with the addition of specialized tools, perform processes such as expanding, countersinking, reaming, and tapping. During machining, the workpiece remains stationary, while the tool moves to align the tool center with the hole center, while the tool rotates (the primary motion). A drilling machine's characteristic is that the workpiece remains stationary while the tool rotates.

[0003] For example, a bench drilling machine with a dual-guide mechanism with the authorization announcement number "CN220278321U" starts the first motor to drive the second support member to rotate, and cooperates with the first adjustment component to drive four groups of first clamps to fix the workpiece. When symmetrical guiding is required, the workpiece is placed on the first clamp, and then the first motor is started, and the second adjustment component drives the two groups of second clamps to clamp and fix the workpiece. Although it is placed on the first clamp, and the two groups of mechanisms are running at the same time, as long as the workpiece is not extremely heavy and does not exceed the force of pulling the first clamp, it will not affect the operation of the two groups of guide mechanisms. Compared with the existing technology, the two guide mechanisms are combined, which can perform both centering clamping and guiding and symmetrical clamping and guiding, which improves adaptability and makes it easier to meet the guiding and fixing requirements of different workpieces. However, the bench drilling machine with a dual-guide mechanism requires the operator to manually adjust the position of the drill bit, which takes a long time to adjust the position of the drill bit for processing, thereby reducing work efficiency. At the same time, the bench drilling machine with a dual-guide mechanism can position the workpiece by simultaneously driving multiple groups of first clamping blocks through the first motor copper when clamping the workpiece. When it is necessary to drill other vertical positions of the workpiece, the workpiece cannot be limited, so that drilling cannot be performed, which increases work limitations. Utility Model Content

[0027] Working principle:

[0028] When using a bench drilling machine with a double guide mechanism to process a workpiece:

[0029] Preparation process:

[0030] The operator first places the workpiece to be processed in the center of the workbench.

[0031] Workpiece limiting process:

[0032] First, according to the position where the workpiece needs to be drilled, adjust the distance that each vertical plate 806 moves, start the power supply of the third motor 802, and the output shaft of the third motor 802 rotates forward to drive the threaded rod 803 to rotate, thereby driving the cross block 804 to slide along the surface of the second fixed column 805. At the same time, the cross block 804 slides along the slide groove processed on the second shell 801. The movement of the cross block 804 drives the vertical plate 806 to move toward the center position of the workbench 1. When the output shaft of the third motor 802 is reversed, the vertical plate 806 moves away from the center position of the workbench 1. First, control the power supply of the four third motors 802. , and at the same time drive the four vertical plates 803 to move toward the center position, fixing the workpiece at the center position of the workbench 1. When the front and rear positions of the workpiece are adjusted as needed, the front and rear two third motors 802 power supplies are started to make the two vertical plates 803 move back and forth synchronously, driving the workpiece to move back and forth. Similarly, when the left and right positions of the workpiece are adjusted as needed, the left and right two third motors 802 power supplies are started to make the two vertical plates 803 move left and right synchronously, driving the workpiece to move left and right, so as to realize the adjustment of multiple positions of the workpiece and punching at different positions of the workpiece, thereby reducing working limitations.

[0033] Workpiece drilling process:

[0034] The operator starts the second motor 502 and the output shaft rotates forward to drive the gear 503 to rotate, thereby driving the rack 504 to move to the right. The rack 504 moves to the right and drives the limit plate 506 to slide to the right along the groove processed on the inner wall of the first shell 501. At the same time, the slider 506 slides to the right along the groove processed on the first shell 501. The slider 506 slides along the groove processed on the bent plate 7. At the same time, along the surface of the first fixed column 507, the slider 506 moves to the right and drives the hydraulic cylinder 4 to move, thereby driving the cross plate 6 to move to the right. The cross plate 6 moves to the right and drives the first motor 3 and the drill bit 2 to move to the right, so that the drill bit 2 can be controlled to move left and right by controlling the forward and reverse rotation of the output shaft of the second motor 502. When the drill bit 2 moves to the appropriate position, the power of the second motor 502 is turned off, and then the operator The operator starts the power supply of the first motor 3, the output shaft of the first motor 3 rotates to drive the drill bit 2 to rotate, starts the power supply of the hydraulic cylinder 4, the telescopic end of the hydraulic cylinder 4 extends to drive the drill bit 4 to move downward, and drills the workpiece. When the drilling is completed, the operator retracts the telescopic end of the hydraulic cylinder 4 to drive the drill bit 2 to reset, then turns off the power supply of the first motor 3, starts the power supplies of multiple third motors 802, reverses the output shafts of multiple third motors 802, drives multiple vertical plates 806 away from the workpiece, and then takes out the processed workpiece. Through the cooperation of the slider 506 and the multiple vertical plates 806, different positions of the workpiece can be drilled, and the multiple vertical plates 806 can perform dual-guide control on the workpiece horizontally and vertically. At the same time, the drill bit 2 can move left and right and up and down with dual guide to drill the workpiece.
