Description

Technical Field

[0001] The utility model relates to the technical field of potting and glue injection, in particular to a chain pin drilling machine. Background Art

[0002] A drilling machine is a punching device. Chains are commonly used parts in the mechanical field, and pin shafts are important components of chains. Generally, one end of the pin shaft is a large diameter end, and the other end is drilled with a pin hole for positioning a positioning pin. Therefore, a drilling machine is needed to drill holes. Some drilling machine solutions have also appeared in the prior art. For example, a workpiece positioning device of a multi-station drilling machine for a pin shaft for a chain recorded in publication number CN219403264U includes a frame, a movable slide plate is fixedly installed on the top of the frame, a horizontal movable plate is movably installed on the bottom of the movable slide plate, a longitudinal sliding plate is movably installed on the bottom of the horizontal movable plate, and a fixed plate is fixedly installed on the top of the movable slide plate;

[0003] The above scheme mainly fixes the pin shaft, but during the fixing process, multiple slides need to be moved to fix it horizontally and vertically. Drilling operations can only be performed after fixing. The pin shaft cannot be fixed synchronously when the drilling rig is lowered, resulting in low drilling efficiency of the device. Utility Model Content

When the drilling rig descends, the pin shaft is fixed synchronously to improve the drilling efficiency of the device.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figures 1 to 4 In the embodiment of the utility model, a chain pin drilling machine includes a workbench 1, an upper surface of the workbench 1 is fixedly connected with a mounting seat 2 near one side, a lower surface of the mounting seat 2 is fixedly connected with a stepping motor 201, an output end of the stepping motor 201 is fixedly connected with a worm 202, the other side surface of the mounting seat 2 is embedded with a rotating shaft 203, the outer surface of the rotating shaft 203 is fixedly connected with a worm gear 204, the outer surface of the rotating shaft 203 is fixedly connected with a rotating cylinder 3, the upper surface of the workbench 1 is fixedly connected with a fixing frame 4, the lower surface of the fixing frame 4 is fixedly connected with a hydraulic cylinder 401, the output end of the hydraulic cylinder 401 is fixedly connected with a lower pressure plate 402, the upper surface of the lower pressure plate 402 is embedded with a drilling rig 403, the lower end of the drilling rig 403 is embedded with a cutter head 404, the upper surface of the workbench 1 is fixedly connected with a connecting seat 5, the other side surface of the connecting seat 5 is embedded with an air pipe joint 501, and the upper surface of the workbench 1 is embedded with a material box 6.

[0023] Specifically, when in use, the pin shaft is placed on the outer surface of the rotating cylinder 3, and the stepper motor 201 is started. The output end of the stepper motor 201 cooperates with the worm 202 and the worm wheel 204 to drive the rotating shaft 203 to rotate, so that the rotating cylinder 3 rotates, and the pin shaft can be moved to the bottom of the fixed frame 4. Then the hydraulic cylinder 401 is started, and the pin shaft is drilled by the drill rig 403 and the cutter head 404. Then the rotating cylinder 3 is rotated again, and the pin shaft can be automatically entered into the discharge box 6, and the air pipe joint 501 is connected to the external air pipe for cleaning the rotating cylinder 3.

[0024] like Figure 1 and 2 As shown, the lower surface of the workbench 1 is fixedly connected with support legs 101 near the four corners, and the upper surface of the workbench 1 and the corresponding positions of the stepper motor 201 are provided with through grooves, and the worm 202 and the worm wheel 204 are meshed and connected.

[0025] In this embodiment, the support leg 101 is used to support the device, and the output end of the stepping motor 201 cooperates with the worm 202 and the worm wheel 204 to drive the rotating shaft 203 to rotate, so that the rotating cylinder 3 rotates.

[0026] like Figure 4 and 3 As shown, air inlet channels 301 are provided on both side surfaces of the rotating cylinder 3, an air storage chamber 302 is provided inside the rotating cylinder 3, an air outlet 303 is provided on the outer surface of the rotating cylinder 3 near the air storage chamber 302, a trapezoidal groove 304 is provided on the outer surface of the rotating cylinder 3, one end of the air pipe joint 501 is nested and connected with a connecting sleeve 502, a No. 2 spring 503 is placed inside the connecting sleeve 502, the other end of the connecting sleeve 502 is embedded and connected with an air outlet pipe 504, and the end of the air outlet pipe 504 is fixedly connected with a connecting ball 505.

[0027] In this embodiment, when the rotating cylinder 3 rotates, under the elastic force of the No. 2 spring 503, the opening position of the air inlet channel 301 squeezes the connecting ball 505, so that the connecting ball 505 drives the air outlet pipe 504 to move outward, thereby separating the connecting ball 505 and the air inlet channel 301. As the rotating cylinder 3 continues to rotate, the connecting ball 505 contacts different air inlet channels 301 to supply air to different air inlet channels 301. The outside air enters the air storage chamber 302 and is sprayed toward the trapezoidal groove 304 from the air outlet 303, so that the waste chips and the pin shaft in the trapezoidal groove 304 are discharged, so as to prevent the chips from affecting the later loading of the trapezoidal groove 304. There are multiple trapezoidal grooves 304, which is convenient for double-station drilling and unloading, and can improve the drilling efficiency of the device.

[0028] In order to make up for the problem that the pin in the trapezoidal groove 304 is not clamped in this embodiment.

[0029] like Figure 4As shown, a fixing rod 405 is embedded and movably connected to the upper surface of the lower pressing plate 402 , a No. 1 spring 406 is nested and connected to the outer surface of the fixing rod 405 , and a pressing plate 407 is fixedly connected to the lower end of the fixing rod 405 .

[0030] In this embodiment, a nut is threadedly connected to the upper end of the fixing rod 405. Under the elastic force of the No. 1 spring 406, the extrusion plate 407 tends to move downward. As the hydraulic cylinder 401 is started, when the extrusion plate 407 contacts the trapezoidal groove 304, the trapezoidal groove 304 limits the extrusion plate 407 and the lower end of the fixing rod 405, so that the drilling rig 403 is more stable when cooperating with the cutter head 404 to drill holes. The pin shaft is located between the extrusion plate 407 and the trapezoidal groove 304 to avoid displacement of the pin shaft during drilling. The pin shaft is fixed synchronously when the drilling rig 403 descends, thereby improving the drilling efficiency of the device.

[0031] like Figure 2 As shown, a screen 601 is fixedly connected to the interior of the material box 6 , and a collecting box 602 is fixedly connected to the front surface of the material box 6 near the screen 601 .

[0032] In this embodiment, under the action of gravity, the debris passes through the screen 601, and the pins enter the collection box 602 along the screen 601, which is convenient for collecting the pins later and further improves the working efficiency of the device.
