Description

TECHNICAL FIELD

[0001] The utility model relates to a drilling mechanical technical field especially relates to a two -way drilling device. BACKGROUND

[0002] In the manufacturing industry, many products in the manufacturing process need to be drilled, and the drilling process is generally completed by a drilling machine. The traditional drilling machine is manually operated for drilling. Such a manual drilling machine not only has a very low working efficiency, but also has a low drilling precision, which does not meet the requirements of industrial production. Therefore, some automatic drilling machines have appeared. Although the working efficiency and the drilling precision are improved, only one hole can be drilled at a time, and the drilling can only be performed from one direction. When producing products that need to be drilled from two directions and have multiple holes in each direction, the efficiency is very low, which does not meet the requirements of mass production.

[0003] Therefore, a full-automatic glass drilling machine applied to glass production and processing is disclosed in Chinese patent No. CN105171932B. The full-automatic glass drilling machine includes a base and a conveying device. The conveying device is located on the base. Vertical support frames are arranged on both sides of the conveying device. An upper horizontal frame is arranged at the upper end of the vertical support frames. A lower horizontal frame is arranged at the lower end of the vertical support frames. A first guide rail is arranged on the upper horizontal frame. An upper drilling mechanism is connected to the first guide rail. The upper drilling mechanism includes an upper drilling seat and an upper drilling frame. A second guide rail is arranged on the lower horizontal frame. A lower drilling mechanism is connected to the second guide rail. The lower drilling mechanism includes a lower drilling seat and a lower drilling frame. The upper drilling mechanism and the lower drilling mechanism are arranged to perform two-way drilling on the workpiece, which improves the drilling efficiency to a certain extent. However, the upper drilling mechanism and the lower drilling mechanism in the patent can only move horizontally along the first guide rail and the second guide rail to adjust the positions of the upper drill bit and the lower drill bit in the horizontal direction. The spacing between the upper drill bit and the lower drill bit in the vertical direction and the rotation angle of the upper drill bit and the lower drill bit in the horizontal direction cannot be adjusted. Therefore, in some scenarios that require multi-angle drilling or scenarios that require high drilling precision, the patent cannot meet the actual product processing requirements.

[0004] Therefore, the prior art needs to be further improved and improved. UTILITY MODEL CONTENTS

[0052] Exemplary embodiments of the present application will be described in greater detail below with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is understood that the present application can be embodied in various forms and should not be limited by the embodiments set forth herein.

[0053] Referring to Figure 1 As shown in the drawings, the present application provides a bidirectional drilling device, which comprises a base 100, a column 200, an upper rocker arm 300 and a lower rocker arm 400. The base 100 is provided with a rotating mechanism 110 at the top, the column 200 is connected with the rotating mechanism 110, and the column 200 has a rotating axis (not shown in the drawings) which is collinear with the center line of the base 100. The upper rocker arm 300 is horizontally connected with the column 200 and is provided with an upper drilling unit 310 with downward drilling direction. The lower rocker arm 400 is correspondingly arranged below the upper rocker arm 300 and is horizontally connected with the column 200 and is provided with a lower drilling unit 410 with upward drilling direction. The upper rocker arm 300 and the lower rocker arm 400 can move along the extension direction of the column 200.

[0054] It should be noted that the bidirectional drilling device provided by the present application can be used as an independent processing equipment to perform single drilling processing on workpieces. It can also be used as a functional module in a comprehensive processing equipment to perform one of the processing functions (i.e. drilling function) possessed by the equipment. Alternatively, it can also be used as a functional unit in a processing system to perform different processing on workpieces through linkage with other processing units. The specific application mode of the bidirectional drilling device is not limited in the present application.

[0055] In addition, the connecting and fixing structure of the bidirectional drilling device varies with the application mode. Specifically, since the base 100 is a supporting and fixing component of the overall device, the base 100 can be connected to different external structures by providing a mounting mechanism (not labeled in the figure) on the base 100. For example, the mounting mechanism can be a connecting hole provided on the base 100, and the base 100 can be fixedly connected to the ground, a workbench, or a mounting seat by cooperating with a fixing hole provided on the ground, the workbench, or the mounting seat through a threaded fastener (such as an anchor bolt, a stud, etc.). Alternatively, the mounting mechanism can be a clamping groove formed on the base 100, and the base 100 can be detachably connected to the ground, the workbench, or the mounting seat by cooperating with a clamping buckle provided on the ground, the workbench, or the mounting seat through clamping. Alternatively, the mounting mechanism can be a magnetic body provided on the base 100, and the base 100 can be magnetically connected to the ground, the workbench, or the mounting seat by cooperating with a magnet provided on the ground, the workbench, or the mounting seat.

[0056] It should be further noted that the base 100 and the column 200 are rotatably connected by the rotation mechanism 110. The specific structure of the rotation mechanism 110 can have various embodiments. For example, the rotation mechanism 110 can be a rotating shaft provided on the top of the base 100, or the rotation mechanism 110 can be a rotating disc that can rotate relative to the base 100, or the rotation mechanism 110 can be a plurality of rollers arranged in a ring shape on the top of the base 100. The specific structure of the rotation mechanism 110 is not limited in the present application.

[0057] The upper drilling unit 310 is a component that directly contacts the workpiece. On the one hand, the upper drilling unit 310 can be composed of an upper drill bit and an upper drill holder for clamping the upper drill bit. The upper drill bit can move up and down in the upper drill holder along its axial direction, so that the upper drilling unit 310 has a telescopic function and further expands the movement stroke of the upper drill bit in the extension direction of the column 200, so that the upper drill bit has a wider drilling range. On the other hand, different types of upper drill bits can be selected to process different types and specifications of holes. For example, the upper drill bit can be a twist drill, a center drill, a triangular drill, a conical hole drill, a cylindrical hole drill, etc. The specific structure of the upper drilling unit 310 is not limited in the present application. It can be understood that the lower drilling unit 410 corresponding to the upper drilling unit 310 has a similar main function as the upper drilling unit 310, and only differs from the upper drilling unit 310 in the drilling direction. Therefore, the specific structure of the lower drilling unit 410 can be referred to the above description, which will not be repeated here.

[0058] The bidirectional drilling device provided by this utility model firstly enables the column 200 to rotate relative to the base 100 along the rotation axis through the setting of the rotating mechanism 110, so that the upper rocker arm 300 and the lower rocker arm 400, which are horizontally connected to the column 200, can rotate with the rotation of the column 200; secondly, the upper drilling unit 310 and the lower drilling unit 410 have opposite drilling directions, so that the device can realize bidirectional drilling of the workpiece; thirdly, through the movement of the upper rocker arm 300 and the lower rocker arm 400 along the extension direction of the column 200, the upper drilling unit 310 can move closer to or further away from the lower drilling unit 410, so that the device can be adapted to workpieces of different types and sizes. The bidirectional drilling device provided in this application, through the above-described structure, can not only adjust the rotation angle of the upper drilling unit 310 and the lower drilling unit 410 in the horizontal direction, but also adjust the distance between the upper drilling unit 310 and the lower drilling unit 410 in the vertical direction. This allows the device to perform drilling processing on the workpiece from multiple different angles. Moreover, in some scenarios where high drilling accuracy is required, this device also has a good drilling effect, thereby enabling the device to meet the processing needs of different products.

[0059] In some embodiments, refer to Figure 2 and Figure 3 As shown, the upper rocker arm 300 includes an upper rocker arm body 320 and an upper guide portion 330 connected to the upper drilling unit 310. The upper rocker arm body 320 has an upper guide portion 321 perpendicular to the rotation axis. The upper guide portion 330 cooperates with the upper guide portion 321 and is capable of horizontal movement along the extension direction of the upper guide portion 321. Correspondingly, the lower rocker arm 400 includes a lower rocker arm body 420 and a lower guide portion 430 connected to the lower drilling unit 410. The lower rocker arm body 420 has a lower guide portion 421 perpendicular to the rotation axis. The lower guide portion 430 cooperates with the lower guide portion 421 and is capable of horizontal movement along the extension direction of the lower guide portion 421.

[0060] It can be understood that, since the upper guide part 321 and the lower guide part 421 are arranged on the upper rocker arm body 320 and the lower rocker arm body 420 respectively, the size of the upper rocker arm body 320 and the lower rocker arm body 420, especially the length of the upper rocker arm body 320 and the lower rocker arm body 420, limits the guiding stroke of the upper guide part 321 and the lower guide part 421 to a certain extent. In addition, the movement range of the upper drilling unit 310 and the lower drilling unit 410 in the horizontal direction mainly depends on the guiding stroke of the upper guide part 321 and the lower guide part 421, so the size of the upper rocker arm body 320 and the lower rocker arm body 420 also indirectly affects the movement range of the upper drilling unit 310 and the lower drilling unit 410. Based on this, the person skilled in the art can flexibly adjust the size of the upper rocker arm body 320, the lower rocker arm body 420, the upper guide part 321 and the lower guide part 421 to realize the adjustment of the movement range of the upper drilling unit 310 and the lower drilling unit 410 during specific implementation.

[0061] As for the cooperation mode between the upper guide part 321 and the upper guide part 330, and the lower guide part 421 and the lower guide part 430, the present application can have various different embodiments. For example, the cooperation between the upper guide part 321 and the upper guide part 330, and the cooperation between the lower guide part 421 and the lower guide part 430 can be rail-guide block cooperation, gear-rack cooperation, sprocket-chain cooperation, pulley-belt cooperation, screw-nut cooperation, etc. In addition, the cooperation mode between the upper guide part 321 and the upper guide part 330 can be the same as or different from the cooperation mode between the lower guide part 421 and the lower guide part 430; for example, the cooperation between the upper guide part 321 and the upper guide part 330 can be rail-guide block cooperation, and the cooperation between the lower guide part 421 and the lower guide part 430 can be rail-guide block cooperation or sprocket-chain cooperation, and the present application is not limited in this regard.

[0062] Preferably, the upper guide part 321 is a screw, and the upper guide part 330 is a nut matched with the screw; the lower guide part 421 is a screw, and the lower guide part 430 is a nut matched with the screw; and in order to further improve the smoothness of the movement process of the upper guide part 321 relative to the upper guide part 330 and the lower guide part 421 relative to the lower guide part 430, a guide rail (not marked in the figure) can also be arranged on the upper rocker arm body 320, and a guide block (not marked in the figure) matched with the guide rail can also be arranged on the upper drilling unit 310; a guide rail (not marked in the figure) can also be arranged on the lower rocker arm body 420, and a guide block (not marked in the figure) matched with the guide rail can also be arranged on the lower drilling unit 410.

[0063] The horizontal movement of the upper drilling unit 310 and the lower drilling unit 410 is realized through the cooperation between the upper guide part 321 and the upper guide part 330 and the cooperation between the lower guide part 421 and the lower guide part 430, so that the bidirectional drilling device has a larger adjustment range, thereby facilitating the improvement of the machining capacity of the device for large-size complex workpieces and the improvement of the machining precision of the device.

[0064] In some embodiments, continuing to refer to Figure 2 and Figure 3 shown, the upper rocker arm 300 further comprises a first driving member 340 connected with the upper guide part 321, and the lower rocker arm 400 further comprises a second driving member 440 connected with the lower guide part 421; wherein the upper drilling unit 310 and the lower drilling unit 410 can be horizontally synchronously moved by the driving of the first driving member 340 and the second driving member 440. Optionally, the first driving member 340 and the second driving member 440 can be driving motors.

[0065] When bidirectional drilling of both sides of a workpiece is needed, especially when the workpiece has holes with the same axis on both sides, the movement mode of the upper drilling unit 310 and the lower drilling unit 410 is configured as horizontal synchronous movement, which can improve the machining precision of the bidirectional drilling device for this type of hole and greatly avoid the situation that the axes of the holes on both sides of the workpiece are not collinear.

[0066] In addition, the horizontal synchronous movement between the upper drilling unit 310 and the lower drilling unit 410 can be realized in the following ways. On the one hand, the first driving member 340 and the second driving member 440 can be configured to have the same parameters such as model, power, and rotation speed, so that the first driving member 340 and the second driving member 440 can synchronously drive the horizontal movement of the upper drilling unit 310 and the lower drilling unit 410. On the other hand, a synchronous transmission shaft can be arranged between the first driving member 340 and the second driving member 440, so that the first driving member 340 and the second driving member 440 can synchronously drive the upper drilling unit 310 and the lower drilling unit 410. At this time, the parameters of the first driving member 340 and the second driving member 440 can be different, and during the specific synchronous transmission, one of the first driving member 340 and the second driving member 440 can not work, and only one driving member works to drive the other driving member to work.

[0067] It can be understood that when the holes on both sides of the workpiece to be machined are not on the same axis, the upper drilling unit 310 and the lower drilling unit 410 can also move asynchronously, so that the upper drilling unit 310 and the lower drilling unit 410 respectively machine the holes on different axes. At this time, the first driving member 340 and the second driving member 440 can be configured to have different parameters such as model, power, and rotation speed, so that the first driving member 340 and the second driving member 440 can asynchronously drive the upper drilling unit 310 and the lower drilling unit 410.

[0068] In some embodiments, referring to Figures 1-4 As shown in the figure, the connecting end of the upper rocker arm body 320 is provided with an upper matching part 322, and the connecting end of the lower rocker arm body 420 is provided with a lower matching part 422. The stand 200 comprises a stand body 210 and a third driving member 220, the stand body 210 has a transmission part 211 parallel to the rotation axis, and the transmission part 211 is matched with the upper matching part 322 and the lower matching part 422 respectively; the third driving member 220 is connected with the transmission part 211 and is used to drive the upper rocker arm body 320 and the lower rocker arm body 420 to move synchronously towards each other or away from each other along the extension direction of the transmission part 211. Optionally, the third driving member 220 can be a driving motor.

[0069] Wherein, the "connecting end" refers to the end of the upper rocker arm body 320 or the lower rocker arm body 420 connected with the stand body 210; the transmission part 211 provided on the stand body 210 is parallel to the rotation axis, that is, the transmission part 211 is arranged on the stand body 210 in the vertical direction. Through the matching between the transmission part 211 and the upper matching part 322 and the lower matching part 422, the transmission of the transmission part 211 to the upper rocker arm body 320 and the lower rocker arm body 420 can be realized. As for the specific structure of the transmission part 211, the upper matching part 322 and the lower matching part 422, the present application can have various different embodiments.

[0070] Preferably, the transmission part 211 is configured as a lead screw, the upper matching part 322 is configured as an upper nut, the lower matching part 422 is configured as a lower nut, and the rotation directions of the upper nut and the lower nut are opposite. This kind of lead screw-nut transmission structure has relatively high transmission precision and transmission efficiency, which can improve the drilling precision of the equipment; in addition, this structure has a certain self-locking ability, which is beneficial to ensure the stability of the upper drilling unit 310 and the lower drilling unit 410 during the drilling operation; in addition, this kind of transmission mode has simple structure, stable movement and high load capacity, which can be well adapted to the bidirectional drilling device.

[0071] It should be noted that, in order to realize the bidirectional drilling operation on the workpiece, the upper drilling unit 310 and the lower drilling unit 410 preferably should be able to approach each other or move away from each other, rather than moving upwards or downwards at the same time. In view of this, the present application configures the upper nut and the lower nut to have opposite rotation directions, and two sections of external threads respectively matched with the rotation directions of the upper nut and the lower nut are formed on the surface of the lead screw, so that when the lead screw rotates in a single direction (such as clockwise or counterclockwise), the upper nut can be driven to approach the lower nut or to move away from the lower nut.

[0072] In some embodiments, continuing to refer to Figures 1-4As shown, the connecting end of the upper rocker arm body 320 is further provided with an upper sliding block 323, and the connecting end of the lower rocker arm body 420 is further provided with a lower sliding block 423. The stand 200 further comprises a sliding rail 212 provided on the stand body 210, and the sliding rail 212 is matched with the upper sliding block 323 and the lower sliding block 423 respectively.

[0073] Through the sliding cooperation among the sliding rail 212, the upper sliding block 323 and the lower sliding block 423, the stability of the movement of the upper rocker arm body 320 and the lower rocker arm body 420 along the extension direction of the stand body 210 can be further improved.

[0074] In some embodiments, referring to Figure 1 and Figure 5 As shown, the rotating mechanism 110 comprises a rotating table 111, a fourth driving member 112 and a transmission assembly (not shown in the figure). The rotating table 111 is connected with the stand body 210 and the base 100 respectively, and the transmission assembly is connected with the rotating table 111 and the fourth driving member 112 respectively, so that the rotating table 111 can rotate along the rotating axis. Optionally, the fourth driving member 112 can be a driving motor.

[0075] Further, the transmission assembly can comprise a turbine (not shown in the figure) located inside the rotating table 111 and a worm (not shown in the figure) connected with the fourth driving member 112, and the worm is engaged with the turbine to transmit the driving force generated by the fourth driving member 112 to the rotating table 111.

[0076] In view of the characteristics of the turbine worm transmission, such as large transmission ratio, large load capacity, compact structure, stable and silent, self-locking ability and the like, the application configures the transmission assembly by adopting the structure, so that the driving force can be transmitted to the rotating table 111 more stably and accurately, thereby realizing the accurate control of the rotating speed and the rotating angle of the rotating table 111, and further improving the drilling effect of the equipment.

[0077] In some embodiments, referring to Figure 5 As shown, the stand body 210 further comprises a support plate 213, a reinforcing plate 214 and a connecting plate 215. The bottom of the support plate 213 is connected with the rotating table 111, and the first side is used for fixing the sliding rail 212. The reinforcing plate 214 is vertically arranged on the second side of the support plate 213. The connecting plate 215 is connected with the top of the support plate 213 and the top of the reinforcing plate 214 respectively.

[0078] Through the arrangement of the reinforcing plate 214, the column body 210 has higher structural strength and higher bearing capacity, thereby facilitating to ensure the connection effect between the column 200 and the upper rocker arm body 320, the lower rocker arm body 420 and the base 100, to keep the upper rocker arm 300 and the lower rocker arm 400 always in parallel state, and to keep the rotation of the column 200 always parallel to the base 100, thereby facilitating to further improve the drilling precision and drilling effect of the equipment.
