Description

Technical Field

[0001] This utility model relates to the field of drilling machine technology, specifically a high-precision constant pressure control system for drilling machines. Background Technology

[0002] Some decorative items often require a large number of rhinestones to enhance their overall aesthetic appeal. In the production of decorative items, rhinestone-filling machines are often used to achieve automatic rhinestone loading.

[0003] Among the relevant technologies, a search revealed that the rotary three-dimensional point drilling machine (publication number CN114393949A) uses negative pressure to hold the drill bit in place. The point drill bit moves perpendicular to the cutting surface of the workpiece where it needs to be processed, and then the drill bit is mounted on the jewelry.

[0004] However, in the above solution, the precision of the dispensing cylinder is required to ensure that the dispensing drill bit is close to the drill when the drill bit is being picked up. Due to the variety of drill shapes, problems such as drill damage and unstable drill picking can easily occur, and improvements are still needed. Utility Model Content

[0005] The purpose of this invention is to provide a high-precision constant pressure control system for a point drilling machine to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-precision point drilling machine constant pressure control system, including a machine body, an assembly plate installed on the machine body, a lifter installed on the assembly plate, and the lifter controls the flexible suction nozzle to approach the drill, which can stably pick up the drill.

[0007] A connecting pipe is connected to the lifting device. A connector is inserted into the lower end of the connecting pipe. A tube is inserted inside the connector and the tube is slidably connected to the connector. A spring is sleeved on the tube. The upper end of the spring presses against the connector. The tube can move up and down to prevent the flexible drill nozzle from pressing on the drill and to ensure that the drill is not damaged.

[0008] The flexible drill bit is connected to the insertion tube. The flexible drill bit uses negative pressure to hold the drill tightly and can hold drills of various shapes, making it more adaptable.

[0009] Furthermore, the machine body is equipped with several material plates, on which drills are placed, which can realize the positioning and placement of drills, and facilitate the precise picking up of drills by the flexible drill suction nozzle.

[0010] Furthermore, the machine body is equipped with front and rear linear modules, and left and right linear modules are installed on the front and rear linear modules. The assembly plate is installed on the left and right linear modules to realize the forward, backward, left and right movement of the flexible drill nozzle, which can move the drill to the location of the jewelry.

[0011] Furthermore, the lifting device includes a cylinder, a guide rail, and a slide. A clamp is installed on the slide, which clamps the connecting pipe to improve the stability of the flexible drill bit lifting.

[0012] Furthermore, the insertion tube has a retaining ring, the lower end of the spring abuts against the retaining ring, and a sealing sleeve is fitted onto the surface of the insertion tube. The sealing sleeve is slidably connected to the insertion joint to improve the sealing effect and stabilize the suction force on the drill. A limiting ring is provided on the inner wall of the insertion joint to block the sealing sleeve and prevent the insertion tube from falling off.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) When the flexible drill bit picks up the drill, the insertion tube connected to the flexible drill bit can slide up and down in the insertion joint without damaging the drill. When the height of the drill is different, the integrity of the drill can be guaranteed. The pressure on the drill is controllable, and the yield rate of the jewelry is higher.

[0015] (2) The spring pushes the insertion tube down to achieve the positioning of the insertion tube and the flexible suction nozzle. When the flexible suction nozzle is controlled by the cylinder to approach the drill, it is positioned by the material plate, making the drill stable and less prone to the problem of empty drilling.

[0016] (3) The flexible drill bit is flexible and can hold drills of different shapes. It can adapt to drills of different shapes and has better compatibility. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example:

[0024] Please see Figure 1-4 This utility model provides a technical solution: a high-precision point drilling machine constant pressure control system, including a machine body 1, an assembly plate 4 installed on the machine body 1, a lifter installed on the assembly plate 4, the lifter controls the flexible suction nozzle 9 to move up and down, and can automatically control the flexible suction nozzle 9 to approach the material plate 17 to suction the drill.

[0025] Connecting pipe 10, which is connected to the lifting device, has a connector 14 inserted into its lower end. The connector 14 is connected to the connecting pipe 10 by plugging and unplugging, which facilitates the replacement of the flexible suction drill nozzle 9.

[0026] The connector 14 has a tube 18 inserted inside, and the tube 18 is slidably connected to the connector 14. A spring 11 is sleeved on the tube 18. The upper end of the spring 11 presses against the connector 14. The spring 11 pushes the tube 18 down, and the flexible suction nozzle 9 connected to the tube 18 is at the bottom, realizing the positioning and automatic reset of the flexible suction nozzle 9.

[0027] The flexible drill nozzle 9 is connected to the insertion tube 18. The flexible drill nozzle 9 uses negative pressure to hold the drill tightly. The flexible drill nozzle 9 can be made of rubber so as not to damage the drill. The flexible drill nozzle 9 can hold drills of different shapes by slight deformation.

[0028] In this embodiment, as Figure 1 As shown, the machine body 1 is provided with several material plates 17, on which drills are placed. The material plates 17 have holes, through which the drills are placed to achieve the positioning of the drills and improve the drill suction accuracy of the flexible drill suction nozzle 9.

[0029] In this embodiment, as Figure 1 As shown, the body 1 is equipped with a front and rear linear module 2, and the front and rear linear module 2 is equipped with a left and right linear module 3. The assembly plate 4 is installed on the left and right linear modules 3. The front and rear linear modules 2 and the left and right linear modules 3 control the front, rear, left and right movement of the flexible drill nozzle 9. In conjunction with the cylinder 5, the cylinder 5 controls the lifting and lowering of the flexible drill nozzle 9 to ensure that the flexible drill nozzle 9 can stably suck up the drill and install the drill on the jewelry.

[0030] In this embodiment, as Figure 2As shown, the lifting device includes a cylinder 5, a guide rail 6, and a slide 7. A clamp 8 is installed on the slide 7, and the clamp 8 clamps the connecting pipe 10. The cylinder 5 and the guide rail 6 are installed on the assembly plate 4. The slide 7 and the guide rail 6 are slidably connected. The clamp 8 uses two screws to clamp the connecting pipe 10.

[0031] In this embodiment, as Figure 3 and Figure 4 As shown, the insertion tube 18 has a retaining ring 13, and the lower end of the spring 11 presses against the retaining ring 13. The spring 11 pushes the insertion tube 18 downward to stabilize it, thereby stably positioning the flexible suction drill nozzle 9.

[0032] In this embodiment, as Figure 3 and Figure 4 As shown, a sealing sleeve 16 is fitted onto the surface of the insertion tube 18. The sealing sleeve 16 is slidably connected to the insertion connector 14 to improve the sealing effect between the insertion tube 18 and the insertion connector 14 and avoid air leakage.

[0033] In this embodiment, as Figure 4 As shown, the inner wall of the connector 14 is provided with a limiting ring 15. The limiting ring 15 blocks the sealing sleeve 16, which can prevent the insertion tube 18 from moving down too much and prevent the insertion tube 18 from separating from the connector 14.

[0034] In this embodiment, as Figure 3 As shown, a quick connector 12 is installed at the upper end of the connecting pipe 10 for easy connection to the pipeline.

[0035] Specifically, during use, the left and right linear modules 3, the front and rear linear modules 2, and the cylinder 5 control the three-axis movement of the flexible drill nozzle 9. The flexible drill nozzle 9 sucks up the drill through negative pressure. When the flexible drill nozzle 9 contacts the drill, the flexible drill nozzle 9 and the insertion tube 18 move upward. The flexible drill nozzle 9 will not excessively press the drill, avoiding drill pressure damage. After sucking up the drill, the spring 11 pushes the retaining ring 13 to reset the flexible drill nozzle 9 and the insertion tube 18, preparing for the next drill sucking. It can adaptively suck up drills of different heights, has good compatibility, and the pressure on the drill is controllable.

[0036] The flexible drill bit 9 can deform slightly. When the shape of the drill is different, the flexible drill bit 9 can better fit the drill by deforming, which improves the stability of the flexible drill bit 9 in sucking the drill and will not cause the problem of empty drill.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
