[0024] Specific implementation and principle

[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with specific embodiments.

[0026] It should be noted that, unless otherwise defined, the technical or scientific terms used in this utility model should have the usual meanings understood by people with ordinary skills in the field to which this utility model belongs. The "first", "second" and similar words used in this utility model do not indicate any order, quantity or importance, but are only used to distinguish different components. "Include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, without excluding other elements or objects. "Connect" or "connected" and similar words are not limited to physical or mechanical connections, but may include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to indicate relative position relationships. When the absolute position of the object being described changes, the relative position relationship may also change accordingly.

[0027] The first aspect of the present invention is as follows Figure 1 and Figure 3 As shown, the present invention integrates drilling equipment into a conveyor line 101, improving production efficiency and reducing equipment costs. Specifically, a mounting base 102 is provided above the conveyor line 101, a drive motor 103 is fixedly mounted on the upper end of the mounting base 102, and a drill bit 107 connected to the drive motor 103 is provided at the lower end of the mounting base 102. The drill bit 107 is configured to be liftable.

[0028] The drilling equipment is integrated into the conveyor line 101. When the precision metal parts to be processed are conveyed to the location of the drilling equipment, they will be blocked by the movable positioning block 109. Therefore, when the precision metal parts are conveyed to the location of the drilling mechanism, they can automatically stop for drilling processing. This not only greatly improves the processing efficiency, but also does not affect the conveying operation of the conveyor line 101 itself.

[0029] In addition, a telescopic cylinder 104 is provided at the upper end of the mounting base 102, and a connecting plate 105 connected to the output shaft of the telescopic cylinder 104 is provided at the lower end of the mounting base 102. A pressure rod 106 is also provided at the lower end of the connecting plate 105 for pressing and fixing precision metal parts. A circular opening is opened in the middle position of the connecting plate 105, and the drill bit 107 is located in the circular opening.

[0030] Preferably, the pressure rod 106 is telescopically and slidably connected to the connecting plate 105, and a buffer member, such as a spring or elastic cotton, is provided between the pressure rod 106 and the connecting plate 105. This makes the pressure rod 106 flexible rather than rigid when pressing the metal part, thus avoiding indentations on the precision metal part due to bumps and wear.

[0031] After the precision metal part stops, the telescopic cylinder 104 drives the pressure rod 106 to press the precision metal part and fix it, which not only achieves accurate positioning of the precision metal part, but also ensures that the precision metal part can remain stable during the drilling operation, thereby performing accurate drilling.

[0032] In order to ensure that the metal parts can be accurately positioned when the drilling equipment is processing them. Figure 2 and Figure 4 As shown, a groove is provided in the middle of the conveyor line 101, and a positioning component for positioning the precision metal parts in operation is fixedly arranged in the groove.

[0033] The positioning assembly includes a positioning seat 108 and a movable positioning block 109. A movable groove 110 is provided in the positioning seat 108. The movable positioning block 109 is slidably connected in the movable groove 110, and a return spring 111 is also provided in the movable groove 110. The upper and lower ends of the return spring 111 are respectively connected to the lower end of the movable positioning block 109 and the bottom of the movable groove 110.

[0034] The height of the movable positioning block 109 in the normal rotation state is higher than the precision metal parts in the conveying state. Therefore, the precision metal parts will be blocked when they move to the position of the movable positioning block 109. By setting the position of the movable positioning block 109 according to the position of the drill bit 107 and other conditions, the function of blocking and positioning the precision metal parts in operation can be achieved.

[0035] Furthermore, conveyor line 101 utilizes elevating rollers for conveying. Each roller has an inner groove beneath it, housing a lifting mechanism for supporting and raising and lowering the roller. This mechanism can be implemented using sophisticated springs, airbags, and other structures. Furthermore, movable positioning blocks 109 are configured in a stepped pattern, with the front lower and the back higher. Therefore, when precision metal parts are pressed down and secured by pressure rod 106, the movable positioning blocks 109 and the rollers are also pressed down with them.

[0036] On the other hand, Figure 5 As shown, after drilling is complete, the drill rises, and telescopic cylinder 104 drives pressure rod 106 upward to release the precision metal part. At this point, the lifting assembly beneath the rollers drives the rollers upward, carrying the precision metal part with them. The movable positioning block 109, affected by air pressure, can only rise slowly, no longer blocking the precision metal part. Therefore, conveyor line 101 can automatically transport the precision metal part to the next processing unit, streamlining the process and saving costs.

[0037] Specifically, an airflow channel 112 is provided at the bottom of the positioning seat 108. The inner end of the airflow channel 112 communicates with the inner cavity of the movable groove 110, and the outer end of the airflow channel 112 communicates with the external atmosphere. A flow blocking plate 113 is provided within the airflow channel 112. The upper end of the flow blocking plate 113 is rotatably connected to the upper wall of the airflow channel 112. The flow blocking plate 113 is also provided with micropores 114. A baffle 115 is also fixedly connected to the bottom of the airflow channel 112 inside the flow blocking plate 113. It should be noted that the movable positioning block 109 is sealed in the movable groove 110 to prevent air in the movable groove 110 from flowing out of the gap between the movable positioning block 109 and the movable groove 110.

[0038] Therefore, when the movable positioning block 109 is pressed down and lowered, the gas in the movable groove 110 is squeezed and flows out from the airflow channel 112 below. During this outflow, the airflow automatically lifts the blocking plate 113 due to its rotatable structure, allowing for smooth exhaust in the airflow channel 112. When the precision metal parts are removed and no longer press on the movable positioning block 109, the movable positioning block 109 rises under the action of the return spring 111. However, when air returns to the airflow channel 112, the blocking plate 113 falls back under its own weight and remains at its lowest point under the action of the baffle 115, rather than rotating in the opposite direction due to the return airflow.

[0039] Therefore, the blocking plate 113 blocks the air flow channel 112, and the air is returned only through the micropores 114 on the blocking plate 113. The return air is restricted and can only be returned slowly. Therefore, the movable groove 110 is in a negative pressure state, and the movable positioning block 109 can only rise slowly. DETAILED DESCRIPTION

[0040] When the precision metal parts are transported by rollers on the conveyor line 101 to the location of the drilling equipment, they will be blocked by the movable positioning block 109. Then the telescopic cylinder 104 drives the pressure rod 106 to descend and press the precision metal parts. The movable positioning block 109 slides up and down and is connected in the movable groove 110. The roller can also be raised and lowered. Therefore, when the precision metal parts are pressed down, they will descend with the movable positioning block 109 and the roller, and finally complete the fixation.

[0041] After the above preparatory work is completed, the drill bit 107 descends to drill. After the drilling process is completed, the drill hole rises, and the telescopic cylinder 104 also drives the pressure rod 106 to rise and release the precision metal parts. At this time, the lifting assembly under the roller drives the roller to rise and the precision metal parts rise. At this time, when the air flow channel 112 returns air, the flow blocking plate 113 will fall back under the action of its own gravity and be at the lowest point under the action of the baffle 115, instead of rotating in the opposite direction under the action of the return airflow. Therefore, the flow blocking plate 113 will block the air flow channel 112, and the air will only be returned through the micropores 114 on the flow blocking plate 113. The return air is restricted and can only be returned slowly. Therefore, the movable groove 110 is in a negative pressure state, and the movable positioning block 109 can only rise slowly.

[0042] The precision metal parts are lifted up first by the rollers, so the movable positioning block 109 can no longer block the precision metal parts, so the conveyor line 101 can automatically convey the precision metal parts to the next processing unit.

[0043] Based on the above, the present invention integrates the drilling equipment into the conveyor line 101. When the precision metal parts to be processed are transported to the location of the drilling equipment, they will be blocked by the movable positioning block 109. This allows the original precision metal parts to automatically stop and be drilled when they are transported to the location of the drilling mechanism. This not only greatly improves processing efficiency, but also does not affect the conveying operation of the conveyor line 101 itself. After the precision metal parts stop, the pressure rod 106 presses the precision metal parts to fix them, which not only achieves accurate positioning of the precision metal parts, but also ensures that the precision metal parts can remain stable during the drilling operation, thereby performing accurate drilling. After the drilling operation is completed, the pressure rod 106 and the drill bit 107 rise to release the precision metal parts. The precision metal parts will rise with the conveyor roller, while the movable positioning block 109 can only rise slowly due to the influence of air pressure and can no longer block the precision metal parts. Therefore, the conveyor line 101 can automatically transport the precision metal parts to the next processing unit, simplifying the process and saving costs.
