The gang drill 400 is driven to move towards the mould 300 by the lifting assembly 200 so as to realize the drilling of the workpiece 600 arranged on the mould 300 by the gang drill 400; the fixing assembly 500 is used for fixing a workpiece 600 to be processed.

It should be understood by those skilled in the art that when the workpiece 600 is fixed to the mold 300 by the fixing assembly 500, the mold 300 and the drill 410 should be located at two sides of the workpiece 600; in the process of drilling the workpiece 600, the workpiece 600 needs to be completely penetrated by the drill bit 410, and the workpiece 600 is supported on the mold 300, so that in order to avoid interference between the drill bit 410 and the mold 300, an avoidance hole for avoiding the drill bit 410 in the gang drill 400 is further formed in the mold 300, and after the drill bit 410 penetrates through the workpiece 600, the drill bit 410 is located in the avoidance hole.

It should be understood by those skilled in the art that, during the drilling process, the main stress position of the workpiece 600 is located at the position of the avoiding hole, so, in order to better clamp the workpiece 600, to avoid the condition that the workpiece 600 shakes during the drilling process, in a preferred embodiment of the present application, the fixing assembly 500 includes a pressing member 510 for cooperating with the mold 300 to clamp the workpiece 600, and the pressing member 510 is partially located between two adjacent avoiding holes. Wherein, the pressing member 510 cooperates with the mold 300 to clamp the workpiece 600 means that the pressing member 510 and the mold 300 apply pressure to the workpiece 600 from both sides of the plate-shaped workpiece 600, respectively, when the workpiece 600 is clamped on the mold 300; the partial location of the compression member 510 between two adjacent avoidance holes means that the partial structure of the compression member 510 is located between the outer common tangent of two adjacent avoidance holes and the connecting line of the circle centers of the two adjacent avoidance holes.

It should be understood to those skilled in the art that the avoidance hole should be set according to the position of the through hole to be machined on the workpiece 600 to be machined, the position of the hole drilled on the workpiece 600 is weak in the process of drilling the workpiece 600, deformation easily occurs, and the force received by the workpiece 600 at the position of the hole drilled in the drilling process is large, so that the deformation of the workpiece 600 in the machining process can be reduced and the machining precision can be improved by the clamping of the clamping piece 510 between two adjacent avoidance holes by the means that the clamping piece 510 is partially located between the two adjacent avoidance holes.

In this application, there is no particular limitation on the specific structure of the compressing element 510, and according to the above preferred embodiment, an optional structure of the compressing element 510 in this application includes a main body and a plurality of protrusions 511 distributed on one side of the main body, where the compressing element 510 is an integral comb-shaped structural member, and one end of the protrusions 511 away from the main body is located between two adjacent avoidance holes, that is, in the extending direction of the main body, the protrusions 511 are arranged with the avoidance holes at intervals. During the drilling process, the material between the two through holes in the work 600 is compressed by the protrusions 511 to reduce deformation of the work 600 and to reduce shaking of the work 600. It should be readily understood by those skilled in the art. The body of the hold-down member 510 is of a length in the direction of the distribution of the relief holes so that the body can better grip the region between the through hole in the workpiece 600 and the edge of the workpiece 600.

Further, as shown in fig. 2, the protruding portions 511 and the main body are both rectangular plate-shaped structures, a gap for avoiding the drill 410 is formed between two adjacent protruding portions 511 and the main body, during the drilling process, the drill 410 is lowered into the gap, holes are drilled in the region of the workpiece 600 located in the gap, and the protruding portions 511 clamp the workpiece 600 under processing from two sides of the drill 410. Preferably, the protrusion 511 is connected to the body through a circular arc transition to reduce stress concentration at the connection location.

The above is only one embodiment of the pressing member 510 provided in the present application, and in other embodiments, the pressing member 510 may be a strip-shaped plate-shaped structural member having a plurality of through holes, where the pressing member 510 is led away from the drill 410 through the through holes, and the workpiece 600 is pressed by the solid portion of the pressing member 510. In this embodiment, the pressing member 510 includes two main bodies, which are a first main body located at one side of the through hole and a second main body located at the other side of the through hole, wherein the first main body and the second main body are elongated, the protruding portion 511 connects the first main body and the second main body from a direction perpendicular to an extending direction of the first main body, that is, one end of the protruding portion 511 is connected with the first main body, and the other end of the protruding portion 511 is connected with the second main body. And the adjacent two protrusions 511, the first body and the second body together form a through hole for avoiding the drill bit 410.

In the above embodiment of the present application, the body is a structural member having a certain length, and in order to enable the body to uniformly transmit the force to the workpiece 600, the body may be made of a material having a good rigidity such as metal, and accordingly, the protrusion 511 may be made of a metal material.

In some embodiments of the present application, the fixing assembly 500 further includes a driving member 520 disposed on the mold 300, where the driving member 520 is connected to the pressing member 510 to drive the pressing member 510 to fix the workpiece 600. The driving member 520 is not limited to being mounted on the mold 300, and in some embodiments, the driving member 520 may be mounted on the frame 100 or the lift assembly 200. Because the pressing member 510 is matched with the mold 300 to clamp the workpiece 600, the driving member 520 is disposed on the mold 300, and the connection between the driving member 520 and the pressing member 510 is equivalent to the manner that the pressing member 510 is disposed on the mold 300, so that the clamping operation of the workpiece 600 is conveniently completed.

The specific structural form of the driving member 520 is not limited in this application, as long as the pressing member 510 can move under the action of the driving member 520, so as to clamp the workpiece 600. In some embodiments, the driving member 520 may be a device capable of outputting a linear motion, such as an air cylinder or a hydraulic cylinder, and the driving member 520 may move the pressing member 510 toward the mold 300, thereby pressing the workpiece 600 against the mold 300. In other embodiments, the driving member 520 may also include a motor and a linkage mechanism, where the motor is in transmission connection with the pressing member 510 through the linkage mechanism, and a person skilled in the art may adjust the linkage mechanism according to actual needs, so as to drive the pressing member 510 to press and fix the workpiece 600 on the mold 300 during the rotation of the motor.

There is no limitation in the position where the driving member 520 and the compressing member 510 are connected to each other, and it is preferable that the driving member 520 is connected to the main body of the compressing member 510.

The gang drill 400 provided by the application comprises a shell and a plurality of drill bits 410 arranged on the shell, wherein the drill bits 410 are in transmission connection through a gear structure, so that under the condition that one drill bit 410 is in transmission connection with a motor, the drill bits 410 can transmit kinetic energy of the motor to other drill bits 410, and the synchronous rotation of the drill bits 410 is realized through one motor.

The gang drill 400 is already known in the art, and the specific structure of the gang drill 400 is not particularly limited in this application, and those skilled in the art can adjust the structure of the gang drill 400 according to actual use needs. For example, the arrangement manner of the drill bits 410 is changed to process the through holes of the workpiece 600 arranged in different arrangement manners, for example, the drill bits 410 are arranged along a straight line to process the holes of the workpiece 600 arranged along the straight line, and the drill bits 410 are arranged along a curved line to process the holes of the workpiece 600 arranged along the curved line.

In some embodiments of the present application, the housing is an elongated structural member, and one lifting assembly 200 is connected to both ends of the housing, and the two lifting assemblies 200 are lifted synchronously to move the gang drill 400 up and down. It should be understood by those skilled in the art that in embodiments where the lift assembly 200 moves the gang drill 400 up and down, the axial direction of the drill bit 410 is parallel to the vertical direction. Since the gang drill 400 is provided with a plurality of drill bits 410 for simultaneously drilling holes at a plurality of positions, the force along the axial direction of the drill bits 410 is large during the drilling process, and by providing one lifting assembly 200 at each end of the housing, a sufficient downward force can be provided to the drill bits 410 of the gang drill 400 to enable the drill bits 410 to drill through the workpiece 600. In addition, in the case that the distribution of the through holes in the workpiece 600 to be processed is not uniform, the distribution of the drill bits 410 is also non-uniform, so that the stress of the gang drill 400 is also non-uniform, and the deflection phenomenon of the gang drill 400 caused by the non-uniform stress in the drilling process can be effectively avoided by setting one lifting assembly 200 at each of the two ends of the shell, and the condition that the holes processed on the workpiece 600 are not satisfactory due to the deflection of the gang drill 400 is avoided.

The specific form of the lifting assembly 200 is not limited in this application, and in some embodiments, the lifting assembly 200 may be a telescopic member such as a cylinder or a hydraulic cylinder, and one end of the lifting assembly 200 is connected to the frame 100, and the other end is connected to the housing. In other embodiments, the lifting assembly 200 may also be a screw-nut mechanism, specifically including a screw and a slider connected with the screw in a transmission manner, in such embodiments, one end of the lifting assembly 200 is connected with the frame 100 by the screw, and the other end of the lifting assembly 200 is fixedly connected with the housing by the slider.

Accordingly, in the embodiment where the lifting assemblies 200 are cylinders or hydraulic cylinders, the lifting assemblies 200 at two ends of the housing may be connected to the same air path or oil path to achieve synchronous lifting of the piston rods of the two lifting assemblies 200. In the case that the lifting assembly 200 is a screw-nut mechanism, a servo motor can be connected to screws in the two lifting assemblies 200, and synchronous lifting of the lifting assemblies 200 can be realized by controlling synchronous rotation of the two servo motors through a control circuit.

In some embodiments of the present application, in order to achieve positioning of the workpiece 600 on the mold 300, a positioning structure for positioning the workpiece 600 is further provided on the mold 300. The positioning mode is not particularly limited, and may be positioning by a positioning pin, or positioning by an edge and a surface in the workpiece 600, and one skilled in the art may select an existing positioning mode according to actual needs.

In some embodiments of the present application, the spacing between the drill bit 410 and the upper surface of the mold 300 is limited due to the gang drill 400 being disposed above and below the mold 300, which is inconvenient for mounting the workpiece 600 on the mold 300. Thus, in some embodiments, the mold 300 is movably disposed on the frame 100, and the movement direction of the mold 300 is perpendicular to the direction in which the gang drill 400 moves toward the mold 300, that is, in embodiments in which the gang drill 400 moves toward the mold 300 in the vertical direction, the movement direction of the mold 300 is the horizontal direction. As shown in fig. 1, 3 and 5, the rack 100 is connected with a sliding rail 110, and the mold 300 is disposed on the sliding rail 110.

Of course, in order to provide sufficient space for mounting the workpiece 600 on the mold 300, in some embodiments, the gang drill 400 and the lifting assembly 200 may be movably disposed on the frame 100 along an axis perpendicular to the drill 410, that is, in this embodiment, the gang drill 400 may be capable of moving in a direction parallel to the axis of the drill 410 or in a direction perpendicular to the axis of the drill 410.

In other embodiments, the interval between the gang drill 400 and the mold 300 is sufficiently large, and the mold 300 may be fixedly disposed on the frame 100.

In some embodiments of the present application, the mold 300 is movably disposed on the frame 100 by using the ball screw mechanism 120. Further, a moving member is connected to the screw in a transmission manner, the moving member is fixedly connected to the mold 300, and the moving member moves along the axial direction of the screw through rotation of the screw. In embodiments where the axis of the drill bit 410 is parallel to the vertical, the lead screw is disposed horizontally. Further, the screw rod can be driven by a servo motor, the servo motor is connected with the screw rod, and the moving distance of the clamping fixture 300 can be controlled by controlling the rotating circle number of the servo motor, so that when the clamping fixture 300 moves back to the lower part of the gang drill 400, the drill bit 410 in the gang drill 400 can still move to the inside of the avoidance hole without interference with the clamping fixture 300.

In one embodiment of the present application, a backing plate 530 made of plastic material is further disposed on the mold 300, where the backing plate 530 is disposed at the position of the avoidance hole and covers the avoidance hole. A gap for clamping the workpiece 600 is formed between the pressing member 510 and the backing plate 530, i.e., the workpiece 600 is clamped between the clamping member and the backing plate 530 during the drilling process.

For those skilled in the art, the size of the relief hole is larger than the size of the drill 410, so in the embodiment where the mold 300 directly contacts the workpiece 600, since the size of the relief hole is larger than the size of the drill 410, the solid portion of the workpiece 600 between the relief hole and the drill 410 lacks support during drilling, and the drill 410 has a downward force on the workpiece 600, so that the size of the through hole machined on the workpiece 600 may be unsatisfactory or the edge of the through hole of the machined workpiece 600 protrudes toward the side contacting the mold 300.

By adopting the processing device provided by the technical scheme, the backing plate 530 made of plastic material is covered on the avoidance hole on the mold 300, and the backing plate 530 directly supports the workpiece 600 in the process of drilling, so that the situation that the workpiece 600 after processing deforms or the through hole on the workpiece 600 does not meet the requirements due to the fact that the workpiece 600 lacks support at the position of the avoidance hole can be avoided.

In addition, since the pad 530 is a plastic structural member after the drill bit 410 penetrates the workpiece 600, the drill bit 410 can also penetrate the pad 530, and the size of the through hole drilled by the drill bit 410 on the pad 530 is identical to the outer diameter of the drill bit 410. Therefore, when the subsequent work 600 is processed, the pad 530 is not replaced, and the previously used pad 530 is used, and the through hole in the pad 530 is equal to the outer diameter of the drill 410, so that deformation of the processed work 600 to the jig 300 side at the through hole position or unsatisfactory processing of the through hole is not caused.

In the present application, the size of the cushion plate 530 is not specifically limited, and the cushion plate 530 may cover a plurality of avoidance holes simultaneously in the distribution direction of the avoidance holes, or each avoidance hole may be covered by a cushion plate 530, which may be set by a person skilled in the art according to actual situations. In the above embodiment, since it is not necessary to reposition the shim plate 530 each time a hole is drilled, the shim plate 530 may be fixedly attached directly to the mold 300, for example, by tightening a threaded fastener onto the mold 300.

It should be understood by those skilled in the art that the direction of movement of the drill bit 410 is parallel to its axis during drilling. In embodiments where the axis of the drill bit 410 is parallel to the vertical, the drill bit 410 is disposed up and down with the mold 300, wherein the drill bit 410 is mounted above the mold 300.

The foregoing description is only of the preferred embodiments of the present application and is not intended to limit the same, but rather, various modifications and variations may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
