[0021] Depend on Figure 1 , Figure 2 and Figure 3 As shown, the utility model includes a workbench 1, and a gear clamping assembly is provided on one side of the workbench 1, and a bracket 15 on which a linear motor 11 is fixed is provided on the other side, a stepper motor 12 connected to a PLC controller 5 is provided at the output end of the linear motor 11, a support plate 13 is provided at the output end of the stepper motor 12, a power motor 14 for clamping a drill bit is provided on one side of the support plate 13 corresponding to the gear clamping assembly, and a detection assembly for through-hole inspection is provided on the other side.

[0022] Specifically, the gear clamping assembly includes a base 2 connected and fixed to the workbench 1, a hollow placing cylinder 20 is provided on the base 2, a limiting boss 21 is arranged around the hollow inner hole wall of the placing cylinder 20, and two sections of limiting tooth grooves 22 are symmetrically arranged on the hollow inner hole wall of the placing cylinder 20; the gear clamping assembly also includes a rotating cylinder 23 arranged on the base 2, and a pressure block 24 is provided at the output end of the rotating cylinder 23, which abuts against the upper end face of the gear for limiting.

[0023] The detection assembly includes a connecting seat 3 fixedly connected to the support plate 13, a supporting block 30 screwed to the connecting seat 3, and a sleeve 31 sleeved on the outside of the supporting block 30. A groove is provided on the supporting block 30, and a proximity switch 4 is fixedly inserted into the bottom of the groove. One end of a compression spring 40 is also connected to the bottom of the groove. The other end of the compression spring 40 is fixedly connected to one end of a guide rod 42, and the other end of the guide rod 42 is inserted with a probe 43 extending out of the sleeve 31.

[0024] A bearing 44 is sleeved at a position in the jacket 31 corresponding to one side of the probe 43 , and a corresponding end of the guide rod 42 is sleeved and passed through a center hole of the bearing 44 .

[0025] The power motor 14 , the rotary cylinder 23 and the proximity switch 4 are all connected to the PLC controller 5 .

[0026] The operating principle of the utility model is as follows:

[0027] like Figures 1 to 3 As shown, first turn the gear ( Figure 1 The gear (as shown in the dotted line position) is placed on the limiting boss 21 in the placing tube 20, and the tooth groove of the gear extends into the two-section limiting tooth groove 22 correspondingly to achieve the purpose of limiting the gear meshing in the horizontal direction. Subsequently, the PLC controller 5 starts the rotating cylinder 23, driving the pressure block 24 to rotate to the top of the gear and move down to abut against the upper end surface of the gear, thereby achieving the limiting fixation of the gear in the vertical direction.

[0028] Then, the PLC controller 5 starts the linear motor 11 and the power motor 14 at the same time, that is, the rotating drill bit moves down to drill a hole on the gear. At this time, the sleeve 31 is not directly above the placement tube 20, that is, when the drill bit and the probe 43 move down at the same time, the probe 43 does not interfere with the movement of the gear or the placement tube 20; after the drilling is completed, the PLC controller 5 starts the linear motor 11 to drive the power motor 14 to move back upward to the standby position. At this time, the linear motor 11 and the power motor 14 are turned off, and the stepper motor 12 is started at the same time to drive the support plate 13 to rotate, that is, the sleeve 31 is synchronously driven to move to the top of the gear. At this time, the probe 43 is located directly above the drilling position. Similarly, the power motor 14 at this time also leaves the position directly above the placement tube 20 and moves to the position directly above the edge position of the base 2. In this way, when the probe moves down for detection, the drill bit will not interfere with the movement of the gear or the placement tube 20 (such as Figure 1 and Figure 2 status shown).

[0029] Subsequently, the PLC controller 5 turns off the stepper motor 12 and restarts the linear motor 11 at the same time, synchronously driving the jacket 31 and the probe 43 to move downward. When the probe 43 is inserted into the drilling position, if the oil hole is not drilled through, the lower end surface of the probe 43 abuts against the bottom of the hole. As the support plate 13 drives the connecting seat 3 and the jacket 31 to continue to move downward, the guide rod 42 gradually moves closer to the proximity switch 4 and squeezes the compression spring 40. At this time, the compression spring 40 plays a role in buffering the movement speed of the guide rod 42, reducing the impact force of the guide rod 42 on the proximity switch 4. When the guide rod 42 abuts against the proximity switch 4, the proximity switch 4 sends a signal to the PLC controller 5 (such as Figure 3 At the dotted line position shown, the proximity switch 4 line passes through the connecting seat 3 and is electrically connected to the PLC controller 5), the PLC controller 5 sends a command to turn off the linear motor 11, and turns on the alarm light to prompt the operator to check and adjust; if the oil hole has been drilled through, the probe 43 will not be interfered with when passing through the drilling position, and the guide rod 42 will not approach and interfere with the proximity switch 4. After the linear motor 11 drives the probe 43 to move down to the set displacement distance, the PLC controller 5 will immediately start the linear motor 11 to drive the probe 43 to move up to the standby position, and then the PLC controller 5 will start the stepping motor 12 to drive the support plate 13 to rotate, that is, synchronously drive the power motor 14 to move to the top of the gear, preparing for the drilling process of the next gear.

[0030] Finally, the PLC controller 5 starts the rotating cylinder 23 to drive the pressing block 24 to move up and rotate horizontally away from the upper position of the gear. The operator manually removes the processed gear. This operation is repeated to achieve the purpose of drilling the gear oil hole and online instant detection.

[0031] It should be noted that when the length required for the probe 43 to detect needs to be adjusted, it is only necessary to twist the sleeve 31 to synchronously drive the support block 30 screwed to the connecting seat 3 to rotate, and use the spiral movement to adjust the use length of the probe 43; in addition, the rotation angle of the stepper motor 12 and the moving distance of the output end of the linear motor 11 need to be tested before processing and set on the PLC controller 5, and the interval period of opening and closing of each electrical component is adjusted according to the motion cycle set after debugging, so that the entire processing link can be carried out in an orderly manner.

[0032] The PLC controller 5 used in this embodiment does not involve the protection content of program modification. It only needs to connect various electrical components and preset usage data. Therefore, the connection status of the PLC controller 5 and various electrical components will not be repeated.
