Description

Technical Field

[0001] The utility model relates to the technical field of drilling machine equipment, in particular to a feeding mechanism of a radial drilling machine. Background Art

[0002] A radial drilling machine is a drilling machine whose rocker arm can rotate and rise and fall around a column, and whose spindle box usually moves horizontally on the rocker arm. When machining holes on a vertical drilling machine, the centering of the tool and the workpiece is achieved by moving the workpiece, which is obviously very inconvenient for some large and heavy workpieces; while a radial drilling machine can use the position of the moving tool axis for centering, which greatly facilitates the machining of holes on large and heavy workpieces in single-piece and small-batch production; the feed mechanism of an existing radial drilling machine is mainly composed of a slide, a guide rail and a slider, and the slide is used to carry the tool; the guide rail, as the reference surface of the slide, determines the motion trajectory of the slide, ensuring that the tool can accurately move along the predetermined path for machining; the slider is a component that performs the feed motion, and is usually driven by a motor to move the slide along the guide rail to achieve the feed action.

[0003] In the prior art, since the guide rail is exposed to the outside, there will be dust on the surface of the guide rail. When the slider moves along the guide rail, there is friction between the slider and the guide rail. As the usage time increases, the contact part between the slider and the guide rail gradually wears out, causing the electric drill installed on the slide to be unable to be in a vertical state, so that the drilling accuracy is affected, and the slider or guide rail needs to be replaced, affecting work efficiency.

[0004] Therefore, a feeding mechanism of a radial drilling machine is proposed. Summary of the invention

[0005] The utility model aims to provide a radial drilling machine feeding mechanism, which can solve the problem that the electric drill on the slide plate cannot be in a vertical state due to wear between the slide block and the guide rail, and needs to be stopped for maintenance, which affects the work efficiency.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a feeding mechanism of a radial drilling machine, comprising a guide rail, a slider is slidably mounted on the guide rail, a slide plate is mounted on the slide plate, a motor and an electric drill are arranged on the slide plate, and the motor is used to drive the slide plate to move;

[0007] A cavity is provided on the slide plate, an air supply mechanism matched with the cavity is provided on the slide plate, an oil tank is installed on the side wall of the cavity, the oil tank is filled with lubricating oil, an atomizing nozzle is installed on the output end of the oil tank, and the atomizing nozzle is used to atomize the lubricating oil, a pressurizing mechanism matched with the oil tank is provided on the slide block, and a lubricating mechanism is provided on the slide plate, and the lubricating mechanism is used to reduce the friction between the slide block and the guide rail;

[0008] The lubrication mechanism comprises a guide groove arranged on the side wall of the slider, a discharge groove is arranged on the side wall of the guide groove, the distance between the side walls of the discharge groove and the guide groove is 1mm, and the output end of the atomizing nozzle is connected with the discharge groove.

[0009] Preferably, the air supply mechanism includes an elastic pad fixedly mounted on the top wall of the guide rail, a roller is mounted on the output end of the motor, the roller cooperates with the elastic pad, a cavity is opened on the elastic pad, and a conduit extending into the oil tank is inserted on the side wall of the cavity.

[0010] First, the staff starts the motor, and the output end of the motor drives the roller to rotate, so that the roller can move on the surface of the elastic pad. Since the guide rail is in a fixed state, the roller will drive the motor installed on the skateboard to move. At this time, the skateboard drives the slider to move, so that the position of the skateboard and the electric drill can be adjusted; at the same time, the cavity is gradually squeezed near the end of the conduit, so the gas in the cavity is squeezed into the oil tank through the conduit. At this time, the lubrication in the oil tank is squeezed out, and under the action of the atomizing nozzle, the lubricating oil can be evenly distributed in the discharge groove, so that the atomized lubricating oil can be sprayed on the position where the slider is about to pass, that is, the slider and the guide rail are lubricated, which reduces the wear of the slider and the guide rail, and ensures that the slider and the skateboard can drive the output end of the electric drill to maintain a vertical state, reduces the frequency of maintenance, and ensures work efficiency.

[0011] Preferably, a support plate is installed on the side wall of the guide rail, a threaded rod is threadedly inserted on the side wall of the skateboard, the threaded rod cooperates with the support plate, and a level is horizontally arranged on the side wall of the skateboard.

[0012] Preferably, a guide rod is installed on the slide plate, a top block is sleeved on the guide rod, and the top block is pushed by the threaded rod.

[0013] As the usage time accumulates, when the slider is slightly worn, the staff can drive the top block to move along the guide rod by twisting the threaded rod, so that when the top block contacts the support plate, the threaded rod is subjected to a reaction force. At this time, the threaded rod drives the slider to swing, so that the slider can be adjusted to a vertical state. Under the action of the spirit level, the staff can observe the status of the electric drill output end of the slider and slide plate, ensuring the accuracy of the electric drill.

[0014] Preferably, an air inlet valve is embedded on the side wall of the cavity close to the conduit.

[0015] When the processing is completed and the slider is reset, the space on the side of the cavity close to the catheter gradually recovers. At this time, the space inhales air from the outside through the intake valve, so that it can prepare for work again.

[0016] Preferably, a sponge is embedded in the guide groove.

[0017] The sponge can limit the flow rate of the mist lubricating oil, so that the mist lubricating oil can be evenly distributed in the guide groove, ensuring that the lubricating oil can be evenly applied to the surface of the guide rail. At the same time, the sponge can prevent debris from entering the gap between the slider and the guide rail, and the mist lubricating oil can impact the sponge when passing through the sponge, thereby blowing off impurities attached to the sponge surface, ensuring that the sponge can remain clean.

[0018] Compared with the prior art, the beneficial effects of the utility model are:

[0019] 1. The present application sets an oil tank, a guide groove, and a discharge groove; the gas in the cavity is squeezed into the oil tank through a conduit, and the lubricant in the oil tank is squeezed out and evenly distributed in the discharge groove, so that the lubricant in an atomized state can be sprayed on the position where the slider is about to pass, that is, the slider and the guide rail are lubricated, the wear of the slider and the guide rail is reduced, and the slider and the slide plate can drive the output end of the electric drill to maintain a vertical state, which reduces the frequency of maintenance and ensures work efficiency.

[0020] 2. The present application provides a sponge, which can limit the flow rate of the mist lubricating oil, so that the mist lubricating oil can be evenly distributed in the guide groove, ensuring that the lubricating oil can be evenly applied to the surface of the guide rail. At the same time, the sponge can prevent debris from entering the gap between the slider and the guide rail, and the mist lubricating oil can impact the sponge when passing through the sponge, thereby blowing off impurities attached to the sponge surface, ensuring that the sponge can remain clean.

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.

[0030] See also Figures 1 to 5 , the utility model provides a technical solution:

[0031] A feeding mechanism of a radial drilling machine comprises a guide rail 1, characterized in that: a slider 2 is slidably mounted on the guide rail 1, a slide plate 3 is mounted on the slide plate 2, a motor 4 and an electric drill 5 are arranged on the slide plate 3, and the motor 4 is used to drive the slide plate 2 to move;

[0032] A cavity 9 is provided on the slide plate 3, and an air supply mechanism matched with the cavity 9 is provided on the slide plate 3. An oil tank 10 is installed on the side wall of the cavity 9, and the oil tank 10 is filled with lubricating oil. An atomizing nozzle 11 is installed on the output end of the oil tank 10, and the atomizing nozzle 11 is used to atomize the lubricating oil. A pressurizing mechanism matched with the oil tank 10 is provided on the slider 2, and a lubricating mechanism is provided on the slide plate 3, and the lubricating mechanism is used to reduce the friction between the slider 2 and the guide rail 1;

[0033] The lubrication mechanism includes a guide groove 14 provided on the side wall of the slider 2. A discharge groove is provided on the side wall of the guide groove 14. The distance between the side wall of the discharge groove and the side wall of the guide groove 14 is 1 mm. The output end of the atomizing nozzle 11 is connected to the discharge groove.

[0034] The air supply mechanism includes an elastic pad 15 fixedly mounted on the top wall of the guide rail 1, a roller 17 is mounted on the output end of the motor 4, the roller 17 cooperates with the elastic pad 15, a cavity 16 is opened on the elastic pad 15, and a conduit 18 extending into the oil tank 10 is inserted on the side wall of the cavity 16.

[0035] First, the staff starts the motor 4. At this time, the output end of the motor 4 drives the roller 17 to rotate, so that the roller 17 can move on the surface of the elastic pad 15. Since the guide rail 1 is in a fixed state, the roller 17 will drive the motor 4 installed on the slide plate 3 to move. At this time, the slide plate 3 drives the slider 2 to move, so that the position of the slide plate 3 and the electric drill 5 can be adjusted; at the same time, the cavity 16 is gradually squeezed near the end of the conduit 18, so the gas in the cavity 16 is squeezed into the oil tank 10 through the conduit 18. At this time, the lubrication in the oil tank 10 is squeezed out, and under the action of the atomizing nozzle 11, the lubricating oil can be evenly distributed in the discharge groove, so that the atomized lubricating oil can be sprayed on the position where the slider 2 is about to pass, that is, the slider 2 and the guide rail 1 are lubricated, the wear degree of the slider 2 and the guide rail 1 is reduced, and it plays a role in ensuring that the slider 2 and the slide plate 3 can drive the output end of the electric drill 5 to maintain a vertical state, reducing the frequency of maintenance and ensuring work efficiency.

[0036] A support plate 6 is installed on the side wall of the guide rail 1 , a threaded rod 7 is threadedly inserted on the side wall of the slide plate 3 , the threaded rod 7 cooperates with the support plate 6 , and a level 8 is horizontally arranged on the side wall of the slide plate 3 .

[0037] A guide rod 12 is installed on the slide plate 3 , and a top block 13 is sleeved on the guide rod 12 . The top block 13 is pushed by the threaded rod 7 .

[0038] As the usage time accumulates, when the slider 2 is slightly worn, the staff can drive the top block 13 to move along the guide rod 12 by screwing the threaded rod 7, so that when the top block 13 contacts the support plate 6, the threaded rod 7 is subjected to a reaction force. At this time, the threaded rod 7 drives the slider 2 to swing, so that the slider 2 can be adjusted to a vertical state, and with the action of the spirit level 8, the staff can observe the state of the output end of the electric drill 5 of the slider 2 and the slide plate 3, thereby ensuring the accuracy of the electric drill 5.

[0039] Specifically, Figure 2 As shown, an air intake valve 19 is embedded on the side wall of the cavity 16 close to the conduit 18 .

[0040] When the processing is completed and the slider 2 is reset, the space on the side of the cavity 16 close to the conduit 18 is gradually restored. At this time, the space inhales air from the outside through the air inlet valve 19, so as to prepare for work again.

[0041] Specifically, Figure 1 As shown, a sponge 20 is embedded in the guide groove 14 .

[0042] The sponge 20 can limit the flow rate of the mist lubricating oil, so that the mist lubricating oil can be evenly distributed in the guide groove 14, which ensures that the lubricating oil can be evenly applied to the surface of the guide rail 1. At the same time, the sponge 20 can prevent debris from entering the gap between the slider 2 and the guide rail 1, and the mist lubricating oil can impact the sponge 20 when passing through the sponge 20, so as to blow away impurities attached to the surface of the sponge 20, ensuring that the sponge 20 can be kept clean.

[0043] Working principle: First, the staff starts the motor 4, and the output end of the motor 4 drives the roller 17 to rotate, so that the roller 17 can move on the surface of the elastic pad 15. Since the guide rail 1 is in a fixed state, the roller 17 will drive the motor 4 installed on the slide 3 to move. At this time, the slide 3 drives the slider 2 to move, so that the position of the slide 3 and the electric drill 5 can be adjusted; at the same time, the cavity 16 is gradually squeezed near the end of the conduit 18, so the gas in the cavity 16 is squeezed into the oil tank 10 through the conduit 18. At this time, the lubrication in the oil tank 10 is squeezed out, and under the action of the atomizing nozzle 11, the lubricating oil can be evenly distributed in the discharge groove, so that the atomized lubricating oil can be sprayed on the slider 2 that is about to move. The position of the path, that is, lubrication of the slider 2 and the guide rail 1, reduces the degree of wear of the slider 2 and the guide rail 1, ensures that the slider 2 and the slide plate 3 can drive the output end of the electric drill 5 to maintain a vertical state, and reduces the frequency of maintenance. With the accumulation of use time, when the slider 2 is slightly worn, the staff can drive the top block 13 to move along the guide rod 12 by twisting the threaded rod 7, so that when the top block 13 contacts the support plate 6, the threaded rod 7 is subjected to a reaction force. At this time, the threaded rod 7 drives the slider 2 to swing, so that the slider 2 can be adjusted to a vertical state, and under the action of the spirit level 8, it is convenient for the staff to observe the state of the output end of the electric drill 5 of the slider 2 and the slide plate 3, thereby ensuring the accuracy of the electric drill 5.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
