DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0027] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0028] The utility model discloses a drilling device for precision instrument processing, which is mainly used in the scene of collecting and processing drilling debris of precision workpieces.

[0029] Reference Figure 1, Figure 2 and Figure 3 , a drilling device for precision instrument processing, comprising a frame shell 1, a liquid injection mechanism 2 is installed on the left side of the frame shell 1, the liquid injection mechanism 2 is used for cooling the drilled hole and flushing the waste chips; a collecting mechanism 3 is arranged in the middle of the frame shell 1, and the collecting mechanism 3 is used for collecting chips; the liquid injection mechanism 2 includes a liquid guide tube 202 running through the middle of the upper end of the left side of the frame shell 1, and the lower end of the right side of the liquid guide tube 202 is connected to an arc-shaped nozzle 203; the collecting mechanism 3 includes an inclined groove 301 opened in the middle of the interior of the frame shell 1, a collecting groove 302 is opened on the right side of the inclined groove 301, and a filter screen 303 is slidably connected to the right side of the interior of the frame shell 1; a motor 8 is installed on the right side of the upper end of the mounting plate 7, and a drill bit 9 is connected to the output end of the lower side of the motor 8, a telescopic cylinder 6 is installed on the left side of the upper end of the frame shell 1, and the lower end of the telescopic cylinder 6 is connected to the mounting plate 7, in which a water pressure pump 201 is installed in the middle of the left side of the frame shell 1, and a liquid storage tank 5 is opened at the lower end of the interior of the frame shell 1;

[0030] In this embodiment, when drilling a precision workpiece, the precision workpiece is first mounted between the two groups of clamps on the left side of the upper end of the frame housing 1. The clamps are driven by the cylinder to clamp the precision workpiece to fix the position. Then, the hydraulic pump 201 is started to extract the coolant from the inside of the liquid storage tank 5. The coolant is introduced from the liquid guide tube 202 to the arc-shaped nozzle 203 to flush the lower end of the drill bit 9. At this time, the motor 8 is started to drive the drill bit 9 to rotate. Then, the telescopic cylinder 6 is extended, and the mounting plate 7 is shifted downward, so that the drill bit 9 and the arc-shaped nozzle 203 are synchronously displaced downward to ensure that the coolant sprayed by the arc-shaped nozzle 203 is always aimed at the lower end of the drill bit 9. At this time, the lower end of the drill bit 9 is in contact with the surface of the workpiece, and the rotating drill bit 9 exerts a downward pressure on the workpiece. The force of the drill bit 9 is applied to generate workpiece debris. When the drill bit 9 contacts the workpiece, the arc nozzle 203 flushes the contact point between the drill bit 9 and the workpiece, which has the effect of cooling the drill bit 9. The coolant can speed up the drilling speed of the workpiece, extend the service life of the drill bit 9, and improve the drilling accuracy of the workpiece. The debris generated by the drilling is flushed to the right into the inclined groove 301, and then slowly enters the collection groove 302. The debris is blocked by the filter 303 to ensure that the debris is accumulated in the collection groove 302, which is convenient for subsequent centralized processing. The coolant passes through the filter 303 to filter the debris and then enters the liquid storage tank 5. After the equipment stops, the concentrated debris flushed to the collection groove 302 by the coolant can be processed.

[0031] Reference Figure 2 and Figure 3 In a preferred embodiment, a flat nozzle 204 is installed on the right side of the arc-shaped spray head 203, and the arc-shaped spray head 203 is connected to the liquid storage tank 5 through the liquid guide tube 202;

[0032] Supplementary explanation: After the coolant enters the arc-shaped nozzle 203, the flat nozzle 204 is set to narrow the liquid outlet, causing the coolant flow to become faster, achieving a jetting effect, and can flush the debris generated by the drill bit 9. The flushed coolant flows through the collecting tank 302 along the inclined groove 301 into the liquid storage tank 5, and then is introduced into the arc-shaped nozzle 203 through the liquid guide tube 202 to form a water circulation, thereby reducing the waste of cooling water resources.

[0033] Reference Figure 1 , Figure 2 and Figure 4 In a preferred embodiment, a clamping mechanism 4 is provided at the front and rear ends of the filter 303, and the clamping mechanism 4 is used to clamp and fix the filter 303 on the frame shell 1. The clamping mechanism 4 includes grooves 401 opened at the front and rear ends of the upper right side of the frame shell 1, and an arc plate 402 is installed in the middle of the groove 401. The arc plate 402 is elastic, and hook blocks 404 are connected to the upper sides of the front and rear ends of the filter 303. A spring 403 is connected to the side of the arc plate 402 away from the filter 303;

[0034] In this embodiment, when the filter screen 303 blocks and filters debris for a long time, it needs to be replaced accordingly. First, the handle at the upper end of the filter screen 303 is held by the hand, and the filter screen 303 is pulled upward from the frame shell 1, so that the hook blocks 404 at the front and rear ends of the filter screen 303 are disengaged from the clamping of the arc plate 402. Then the entire filter screen 303 is pulled out, and a new filter screen 303 is replaced and inserted into the original position. When the hook block 404 is inserted into the position between the arc plate 402 in the groove 401 and the inner wall of the frame shell 1, the arc plate 402 is forced to bend toward the spring side. When the hook block 404 is fully inserted, the hook block 404 is clamped by the elastic reset characteristic of the arc plate 402 itself. At the same time, the spring 403 gives the arc plate 402 an inward squeezing force, which increases the clamping effect of the arc plate 402 on the hook block 404, so that the filter screen 303 is fixed in the frame shell 1, and the replacement of the filter screen 303 is completed.

[0035] Working principle: When drilling a precision workpiece, first install the precision workpiece between the two groups of clamps on the left side of the upper end of the frame shell 1, and the clamp is driven by the cylinder to clamp the precision workpiece to fix the position, then start the hydraulic pump 201 to extract the coolant from the inside of the liquid storage tank 5, and the coolant is introduced from the liquid guide tube 202 to the arc-shaped nozzle 203 to flush the lower end of the drill bit 9. At this time, start the motor 8 to drive the drill bit 9 to rotate, then extend the telescopic cylinder 6, and move the mounting plate 7 downward, so that the drill bit 9 and the arc-shaped nozzle 203 move downward synchronously to ensure that the coolant sprayed by the arc-shaped nozzle 203 is always aimed at the lower end of the drill bit 9. At this time, the lower end of the drill bit 9 contacts the surface of the workpiece, and the rotating drill bit 9 exerts pressure on the workpiece. The downward force generates workpiece debris. When the drill bit 9 contacts the workpiece, the arc-shaped nozzle 203 flushes the contact point between the drill bit 9 and the workpiece, which has the effect of cooling the drill bit 9. The coolant can speed up the drilling speed of the workpiece, extend the service life of the drill bit 9, and improve the drilling accuracy of the workpiece. The debris generated by the drilling is flushed to the right into the inclined groove 301, and then slowly enters the collection groove 302. The debris is blocked by the filter 303 to ensure that the debris is accumulated in the collection groove 302, which is convenient for subsequent centralized processing. The coolant passes through the filter 303 to filter the debris and then enters the liquid storage tank 5. After the equipment stops, the concentrated debris flushed to the collection groove 302 by the coolant can be processed.

[0036] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
