Description

Technical Field

[0001] The present application relates to the technical field of punching equipment, and specifically discloses a punching equipment for a machining center. Background Art

[0002] Punching equipment is a mechanical device used to create holes in various materials and is widely used in many industries;

[0003] A machining center is a CNC machine tool with automatic tool change capability that can perform a variety of machining operations;

[0004] However, it should be made clear that not all holes can be punched using a machining center. For example, holes can be drilled in concave surfaces or concave areas of anisotropic surfaces. Drilling holes in such special locations cannot be done using CNC machine tools. The reason for this is not because the tool cannot be moved, but because the workpiece cannot be clamped at all. A specific clamping mold is required. Such holes are usually small-volume pieces, and most parties are unwilling to bear the mold costs. Therefore, a machining center not only requires high-precision equipment such as CNC machine tools, but also handheld punching equipment to perform drilling on surfaces that are not accessible to the machining center. Traditional handheld parts have the problem of unstable drilling. In view of this, the inventor proposes a punching device for a machining center. Summary of the invention

[0005] The purpose of the invention is to solve the problem of unstable drilling of traditional handheld drilling equipment.

[0006] In order to achieve the above object, the present invention provides the following basic scheme:

[0007] A punching device for a machining center comprises a punching assembly, a sliding assembly connected to the punching assembly for vertical sliding movement, and a fixing assembly for fixing the sliding assembly;

[0008] The punching assembly includes a first handle, a driving unit built into the first handle, a motor driven by the driving unit and arranged at one end of the first handle, and a punching group, wherein a drill bit is installed on the punching group;

[0009] Sliding assembly: comprising a connecting block fixedly connected to the first handle, a plurality of guide rails slidably connected to the connecting block, a connecting plate arranged above the connecting block and a second handle fixedly connected to the connecting plate, one end of the guide rail passing through and fixedly connected to the connecting plate and a scale is provided on the guide rail;

[0010] A fixing assembly comprising a collar detachably connected to the second handle and an elastic rope arranged on the guide rail, wherein the free end of the elastic rope is fixedly connected to the collar;

[0011] It also includes a plurality of laser generators arranged on the drilling group, and the convergence point of the laser generators is on the extension line of the central axis of the drill bit.

[0012] The principles and effects of this basic solution are:

[0013] 1. Compared with the prior art, this device has a simple structure and ingenious design. The biggest problem of handheld punching equipment is unstable drilling, which includes the skewness of the hole, the drilling depth of the hole and the inability to find the accurate drilling point. This device can improve the above three problems, thereby solving the problem of unstable drilling in traditional handheld punching equipment.

[0014] 2. Compared with the prior art, the skewness of the hole is improved: the device is provided with a sliding component, and the punching component can be slid up and down on the sliding component to ensure that the punching component punches vertically, and the skewness of the traditional handheld punching can be improved.

[0015] 3. Compared with the prior art, in terms of improvement in the drilling depth of the hole: improvements are made directly on the sliding component. Since the punching component slides up and down on the sliding component, it is only necessary to make a scale design on the sliding component to convert the sliding amount of the punching component sliding up and down on the sliding component into data, and the data can be consistent with the drilling depth of the hole. Therefore, in terms of improvement in the drilling depth of the hole, the drilling depth can be accurately judged.

[0016] 4. Compared with the prior art, when it is difficult to find the exact punching point: laser aiming is adopted, and the laser aiming point is used to aim at the punching point. The laser aiming point is on the extension line of the drill bit. Therefore, when the laser aiming point is consistent with the punching point, the fixing component is used to directly fix the sliding component, so that the sliding component does not move in the up and down directions. When the sliding component does not move in the up and down directions, only the punching component slides up and down on the sliding component. Since the laser aiming point is on the extension line of the drill bit, the punching point of the drill bit can be accurately captured. Therefore, when it is difficult to find the exact punching point, this device has an advantage.

[0017] 5. Compared with the existing technology, this device is miniaturized and simplified, has advantages in drill bits, adopts the characteristics of external motor and battery structure, has certain cost performance and quick replacement.

[0018] Furthermore, the driving unit includes a battery pack and a plurality of electrical connection wires, and the battery pack supplies power to the motor to drive the output shaft of the motor to rotate. The battery pack and the electrical connection wires are electrically connected to drive the output shaft of the motor to rotate, thereby making the device portable and avoiding the limitations of the socket electrical connection.

[0019] Furthermore, the punching group is provided on the rotating block at the bottom of the connecting block and the groove on the rotating block, the groove is evenly provided with slots connected to the groove, the bottom of the connecting block is provided with a circular groove, the rotating block is rotatably connected to the circular groove, the output shaft of the motor is rotatably connected to the rotating block, and the drill bit is adapted to the groove and the slot. The rotation of the rotating block is realized and then the drill bit is driven to rotate. The advantage of such a design is that it avoids the damage to the motor output shaft that may be caused by the direct rigid connection between the drill bit and the output shaft of the motor, and the rotatable connection between the rotating block and the circular groove improves the smoothness of the rotation of the rotating block.

[0020] Furthermore, the drill bit includes a head and a body, the shape and size of the body are adapted to the groove, plug blocks are fixed around the body, the shape, position, size and number of the plug blocks are adapted to the circular groove, and the size of the head depends on the size of the hole. The drill bit includes a head and a body, the body in the drill bit is a standard part, so that all drill bits can be coaxially connected to the rotating block, and the head is a non-standard part, because the size of the hole depends on the plan, because the drill bit needs to be replaced, therefore, the head is replaced with a non-standard part for better drilling, providing a variety of options, convenient operation, and convenient installation and replacement of the drill bit.

[0021] Furthermore, a plurality of mounting blocks are fixedly connected around the bottom of the rotating block, and the bottom surface of the mounting block is an inclined surface, on which a laser generator is mounted, and the laser generator is installed at an angle, so that the lasers emitted by the laser generator converge at the same point. The lasers emitted by the laser generator converge at the same point in order to give the staff relevant reminders, thereby fixing the sliding assembly and achieving precise drilling.

[0022] Furthermore, the connection block is provided with through grooves around it, the guide rail slides up and down in the through grooves, a connecting ring is provided at the connection between the guide rail and the through groove, and the connecting ring is detachably connected to the guide rail.

[0023] Furthermore, it also includes a locking ring assembly for fixing the collar, the locking ring assembly is a latch rod for connecting the collar with a latch, and the latch rod is fixed vertically to achieve precise drilling.

[0025] Furthermore, the first handle and the second handle are both provided with mesh anti-skid patterns, so as to ensure that the first handle and the second handle have sufficient friction when in use, and avoid the occurrence of hand-held slippage.

[0026] Furthermore, the locking ring assembly is used after the laser generator, and when the convergence point of the laser generator is aligned with the punching position, the locking ring assembly is used to fix the collar. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the specific implementation mode, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0036] The figure marks in the drawings of the specification include: first handle 1, anti-slip pattern 2, cavity 3, battery pack 4, end cover 5, connecting block 6, connecting plate 7, guide rail 8, second handle 9, rotating block 10, drill bit 11, motor 12, slot 13, body 14, circular groove 15, gathering point 16, mounting block 17, elastic rope 18, ring 19, fixing surface 20, connecting hole 21, and latch rod 22.

[0037] Implementation example Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown:

[0038] A punching device for a machining center comprises a punching assembly, a sliding assembly connected to the punching assembly for vertical sliding movement, and a fixing assembly for fixing the sliding assembly;

[0039] The punching assembly includes a first handle 1, a driving unit built into the first handle 1, a motor 12 driven by the driving unit and arranged at the end of the first handle 1, and a punching group, on which a drill bit 11 is installed;

[0040] Regarding the first handle 1: the first handle 1 is a cylinder, and a cavity 3 is provided inside the cylinder. The cavity 3 is used to install the drive unit. The right end of the cavity 3 is clamped with an end cap 5, which is used to fix the drive unit and enable the drive unit to form an electrical circuit to complete the power supply to the motor 12;

[0041] About the drive unit: The drive unit includes a battery pack 4 and a plurality of electrical connection wires, and the battery pack 4 supplies power to the motor 12 to drive the output shaft of the motor 12 to rotate. The battery pack 4 and the electrical connection wires are electrically connected to drive the output shaft of the motor 12 to rotate, thereby making the device portable and avoiding the limitations of the socket electrical connection.

[0042] Sliding assembly: comprising a connecting block 6 fixedly connected to the first handle 1, a plurality of guide rails 8 slidably connected to the connecting block 6, a connecting plate 7 arranged above the connecting block 6 and a second handle 9 fixedly connected to the connecting plate 7, one end of the guide rail 8 passing through and fixedly connected to the connecting plate 7 and a scale is provided on the guide rail 8;

[0043] Specifically: the connecting block 6 is provided with through grooves around it, the guide rail 8 slides up and down in the through grooves, a connecting ring is provided at the connection between the guide rail 8 and the through grooves, the connecting ring is detachably connected to the guide rail 8, and the other end of the guide rail 8 passes through the connecting block 6 to determine a sufficiently long length;

[0044] About the use of scale:

[0045] The drill bit 11 contacts the workpiece but does not act on the workpiece. At this time, the lower end face of the connecting block 6 is the zero scale line. When the drill bit 11 drills downward to a certain depth, the connecting block 6 will also move downward. The sliding amount of the punching component sliding up and down on the sliding component can be converted into data, and the data can be consistent with the drilling depth of the hole. Therefore, the drilling depth can be accurately judged by improving the drilling depth of the hole.

[0046] About the role of the connecting ring:

[0047] Fully considering the actual situation of drilling, since the drilling may not ensure rapid drilling to a certain depth, that is, the drill bit 11 stays on the surface of the workpiece, in order to ensure the accuracy of drilling, a connecting ring is needed. After the connecting ring is inserted into the through groove from the upper end of the connecting block 6, the connecting block 6 cannot move downward, avoiding damage to the drill bit 11 caused by the forced downward movement of the connecting block 6. This damage may be the bending of the drill bit 11. Therefore, from this point of view, the designed connecting ring can ensure the accuracy of drilling to a certain extent.

[0048] The punching group is arranged on the rotating block 10 at the bottom of the connecting block 6 and the groove opened on the rotating block 10. The groove is evenly surrounded by slots 13 connected to the groove. The bottom of the connecting block 6 is provided with a circular groove 15. The rotating block 10 is rotatably connected to the circular groove 15. The output shaft of the motor 12 is rotatably connected to the rotating block 10. The drill bit 11 is adapted to the groove and the slot 13. The rotation of the rotating block 10 is realized and then the drill bit 11 is driven to rotate. The advantage of such a design is that it avoids the damage to the output shaft of the motor 12 caused by the direct rigid connection between the drill bit 11 and the output shaft of the motor 12. The rotatable connection between the rotating block 10 and the circular groove 15 improves the smoothness of the rotation of the rotating block 10.

[0049] Regarding drill bit 11 mentioned above:

[0050] The drill bit 11 includes a head and a body 14. The shape and size of the body 14 match the groove. Insert blocks are fixed around the body 14. The shape, position, size and number of the insert blocks match the circular groove 15. The size of the head depends on the size of the hole. The drill bit 11 includes a head and a body 14. The body 14 in the drill bit 11 is a standard part so that all drill bits 11 can be coaxially connected to the rotating block 10. The head adopts a non-standard part because the size of the hole depends on the drilling plan. Because the drill bit 11 needs to be replaced, the head is replaced with a non-standard part in order to better drill the hole, provide a variety of options, and facilitate operation and installation and replacement of the drill bit 11.

[0051] A fixing assembly: comprising a ring 19 detachably connected to the second handle 9 and an elastic rope 18 arranged on the guide rail 8, wherein the free end of the elastic rope 18 is fixed to the ring 19;

[0052] This implementation designs two different fixed components:

[0053] The first type: it also includes a locking ring assembly for fixing the collar 19, the locking ring assembly is a latch rod 22 for latching the collar 19, and the latch rod 22 is fixed vertically to achieve precise drilling.

[0054] Specifically: after the latch rod 22 is vertically fixed on the fixed surface 20, the latch rod 22 connected by the latch of the collar 19 is connected to the collar 19, so that the collar 19 does not move. When the collar 19 does not move, the connecting plate 7 does not move. When the connecting plate 7 does not move, as long as the drill bit 11 is aligned with the punching point, the punching will not be inaccurate.

[0055] The second type: further comprising a locking ring assembly for fixing the collar 19, wherein the locking ring assembly comprises a fixing surface 20 and a connecting hole 21 opened on the collar 19, wherein the connecting hole 21 is connected with a screw, and the fixing surface 20 and the collar 19 are connected by the screw, so as to realize precise drilling.

[0056] Specifically: the fixing surface 20 and the collar 19 are connected by screws so that the collar 19 does not move. When the collar 19 does not move, the connecting plate 7 does not move. When the connecting plate 7 does not move, as long as the drill bit 11 is aligned with the punching point, the punching will not be inaccurate.

[0057] Regarding the alignment of the drill bit 11 with the punching point, a laser generator was used in this case;

[0058] It also includes a plurality of laser generators arranged on the drilling group, and the convergence point 16 of the laser generators is on the extension line of the central axis of the drill bit 11.

[0059] Specifically: Several mounting blocks 17 are fixed around the bottom of the rotating block 10. The bottom surface of the mounting block 17 is an inclined surface. The laser generator is installed on the inclined surface. The laser generator is installed obliquely, and the lasers emitted by the laser generator are gathered at the same point. The lasers emitted by the laser generator are gathered at the same point to give relevant reminders to the staff, thereby fixing the sliding component and achieving accurate drilling.

[0060] Specific implementation process:

[0061] The first step, such as Figures 1 to 7 As shown, install the device, and then fix the workpiece to be punched. No special mold is needed for fixing, and it is sufficient that the workpiece to be punched does not shake. According to the design drawing, use a pen to mark the punching points on the workpiece to be punched;

[0062] In the second step, the first handle 1 is held in the right hand, the second handle 9 is held in the left hand, the device is moved as a whole, the laser generator is turned on, and the convergence point 16 of the laser generator is aligned with the punching point. After alignment, the locking ring assembly is used to fix the connecting plate 7. When fixing the connecting plate 7, it is necessary to ensure that the convergence point 16 of the laser generator is aligned with the punching point.

[0063] The third step is to release the left hand, and use both hands to act on the first handle 1 to move the first handle 1 downward so that the drill bit 11 begins to contact the surface of the workpiece. At this time, the lower end face of the connecting block 6 is the zero scale line. Remember the scale at this time, and then start drilling. According to the design requirements of the drawing, continue to move the first handle 1 downward. At this time, there is a distance change between the lower end face of the connecting block 6 and the guide rail 8. This distance change is digitized by the ruler, and then the depth of the drilling is determined.

[0064] The device solves the problem of unstable drilling in traditional handheld drilling equipment.

[0065] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not used to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
