The present invention can perform drilling processing on the inclined surface of the conveyed punch body by setting a drilling assembly. When the drilling assembly is working, the punch body can be drilled by the drilling machine. When the trigger plate rises and slides into the fixed frame, it is blocked by the limit plate, and at the same time, the contact switch is pressed to turn on the indicator light and the nozzle, which is used to prompt people to start the drilling operation and lubricate the punch body, so as to facilitate drilling; 3.

At this time, since the rectangular block also slides upward, the push rod drives the rubber block to slide toward the inside of the conveying groove under the push of the inclined surface of the rectangular block until one side of the rubber block fits with the inner wall of the conveying groove, so that the conveying block can be limited.

By setting a drilling assembly, the inclined surface of the conveyed punch body 7 can be drilled, and the drilling assembly can also constrain the storage plate 5 after jacking to prevent slippage, making subsequent drilling more stable. By setting a connecting device, the punch body 7 can be conveyed to the inside of the drilling assembly and then the power transmission can be released, and the clamping assembly and the positioning device can be triggered to position the punch body 7 and the conveying block 16. Positioning the punch body 7 can prevent shaking during subsequent drilling, and positioning the conveying block 16 can In order to prevent the conveying block 16 from sliding during the processing of the punch body 7, causing the punch body 7 to be displaced and affecting the drilling process, and at the same time facilitating the resetting of the subsequent connecting components, by setting a clamping component, the punch body 7 can be limited to make the punch body 7 more secure, and by setting a positioning device, the conveying block 16 can be positioned and constrained to prevent shaking, and at the same time facilitate the resetting of the subsequent connecting components.

After sliding to the inside of the drilling component, after the guide strips 3 completely slide out of the guide groove 21, the limit on the storage plate 5 can be released, and at this time, the storage plate 5 can be lifted upward under the action of the lifting spring 41.

[0021] like Figure 3 , Figure 4 , Figure 5 and Figure 6As shown, the drilling assembly includes a fixed frame 8, two vertical plates 6 are fixed to the bottom of the fixed frame 8, and the two vertical plates 6 are fixed to the rear side of the workbench 1.

Indicator lights 11 are fixed on both sides of the fixed frame 8, and the two indicator lights 11 are electrically connected to the contact switches 18 accordingly.

[0022] The effect achieved is that when the storage plate 5 is slid into the interior of the fixed frame 8, the guide strip 3 completely slides out from the guide groove 21. At this time, the storage plate 5 will be lifted upward to the bottom of the limit plate 13 under the action of the elastic force of the lifting spring 41. At this time, the contact switch 18 will be pressed to turn on the indicator light 11 and the nozzle 17 to prompt people to start the drilling operation and lubricate the punch body 7. Then the punch body 7 can be drilled by manually operating the drilling machine 9. The limit plate 13 is set on the rear side of the guide strip 3, and a gap is left between the bottom of the limit plate 13 and the top of the guide strip 3, so that the storage plate 5 can be limited by the guide strip 3 when it does not slide into the interior of the fixed frame 8.

[0023] like Figure 2 , Figure 4 , Figure 5 and Figure 6As shown, the connection device includes a rectangular block 44, both sides of the rectangular block 44 are inclined near the top edge, the transmission block 16 is internally rotatably connected with a drive sleeve 19, both ends of the drive sleeve 19 extend to the front and rear sides of the transmission block 16, and two limit rings 37 are fixed on the outer surface of the drive sleeve 19, and the two limit rings 37 are correspondingly slidably engaged in the interior of the transmission block 16, and a rectangular cavity 42 is provided inside the transmission block 16, and the rectangular block 44 is slidably connected to the interior of the rectangular cavity 42, and a limit cavity 43 is provided on the outer surface of the drive sleeve 19, and the limit cavity 43 is located directly below the rectangular cavity 42, and the bottom of the rectangular block 44 extends and engages in the interior of the limit cavity 43, and a motor 14 is fixed to the front side of the transmission slot 4, and a screw rod 12 is fixed to the output end of the motor 14, and one end of the screw rod 12 is rotatably connected to the inner wall of the transmission slot 4, and the drive The movable sleeve 19 is fitted onto the outer surface of the screw rod 12 and is threadedly connected to the screw rod 12. A lifting cavity 38 is provided inside the conveying block 16 above the rectangular cavity 42. A lifting rod 39 is provided inside the lifting cavity 38. The top of the lifting rod 39 slides through the top of the conveying block 16 and is connected to the bottom of the storage plate 5. The bottom of the lifting rod 39 slides through the inside of the rectangular cavity 42 and is fixed to the top of the rectangular block 44. A support plate 40 is fixed to the outer surface of the lifting rod 39. The support plate 40 is located inside the lifting cavity 38. A lifting spring 41 is fixed between the bottom of the support plate 40 and the inner bottom surface of the lifting cavity 38. First copper sheets 45 are fixed to the inner walls on both sides of the lifting cavity 38, and second copper sheets 46 are fixed to both sides of the support plate 40. The two first copper sheets 45 and the two second copper sheets 46 fit each other correspondingly.

[0024] The effect achieved is that when the storage plate 5 does not slide into the interior of the fixed frame 8, the bottom of the rectangular block 44 will extend into the interior of the limiting cavity 43. Under the mutual engagement of the rectangular block 44 and the limiting cavity 43, the driving sleeve 19 and the transmission block 16 will not rotate relative to each other. Under the drive of the screw rod 12, the driving sleeve 19 and the transmission block 16 will slide together. When the storage plate 5 slides into the interior of the fixed frame 8, the storage plate 5 is lifted upward under the action of the elastic force of the lifting spring 41, and the rectangular block 4 is driven at the same time. 4 slides upward, so that the bottom of the rectangular block 44 slides out from the limiting cavity 43. At this time, the driving sleeve 19 and the conveying block 16 are in a state of being released from the constraints, and the driving sleeve 19 and the conveying block 16 can rotate relatively. At the same time, when the lifting rod 39 slides upward, the first copper sheet 45 and the second copper sheet 46 are separated from each other. In actual use, the first copper sheet 45 and the second copper sheet 46 are the on-off contacts of the circuit of the control motor 14, so the motor 14 stops working when the first copper sheet 45 and the second copper sheet 46 are separated from each other.

[0025] like Figure 2 , Figure 3 , Figure 5 , Figure 7 and Figure 8As shown, the clamping assembly includes a pressure rod 23, a reciprocating cavity 22 is opened inside the storage plate 5, the pressure rod 23 is located inside the reciprocating cavity 22, a hexagonal cavity 26 is opened at the bottom of the storage plate 5, the bottom of the hexagonal cavity 26 penetrates into the interior of the conveying block 16, one end of the pressure rod 23 slides through to one side of the inner wall of the storage groove 20, a hexagonal rod 27 is fixed to the inner top surface of the hexagonal cavity 26, a wedge-shaped opening 29 is opened on one side of the hexagonal rod 27, the inner bottom surface of the wedge-shaped opening 29 is inclined, the other end of the pressure rod 23 slides through to the inside of the hexagonal cavity 26, and extends to the inside of the wedge-shaped opening 29 to fit into the inclined surface, a limiting rod 28 is fixed to the bottom of the hexagonal rod 27, a fixing ring 24 is fixed to the outer surface of the pressure rod 23, the fixing ring 24 is located between the inner walls of the reciprocating cavity 22, and a reciprocating spring 25 is fixed between one side of the fixing ring 24 and one side of the inner wall of the reciprocating cavity 22.

[0026] The effect achieved is that when the storage plate 5 slides upward, the hexagonal rod 27 will slide upward. At this time, the inclined surface of the bottom surface of the wedge-shaped opening 29 will push the pressure rod 23 to one side when sliding upward, so that one end of the pressure rod 23 slides into the storage groove 20 to press the punch body 7.

[0027] like Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, the positioning device includes a push rod 34, an adjusting cavity 33 is formed inside the conveying block 16, the push rod 34 is located inside the adjusting cavity 33, a fixing plate 36 is fixed to the outer surface of the push rod 34, one side of the fixing plate 36 is inclined near the edge of the outer surface, the bottom of the limit rod 28 slides through the inside of the adjusting cavity 33, and fits with the inclined surface of one side of the fixing plate 36, a push spring 35 is fixed between one side of the fixing plate 36 and one side inner wall of the adjusting cavity 33, one end of the push rod 34 slides through the inside of the rectangular cavity 42, and fits with the inclined surface of one side of the rectangular block 44, a receiving groove 31 is provided on the outer surface of the conveying block 16, a rubber block 32 is arranged inside the receiving groove 31, the other end of the push rod 34 slides through the inside of the receiving groove 31, and is fixed to one side of the rubber block 32.

[0028] The effect achieved is that when the storage plate 5 drives the hexagonal rod 27 to slide upward, the limit rod 28 will slide upward, releasing the limit on the fixed plate 36. At this time, since the rectangular block 44 also slides upward, the push rod 34 drives the rubber block 32 to slide into the conveying groove 4 under the push of the inclined surface of the rectangular block 44, until one side of the rubber block 32 is in contact with the inner wall of the conveying groove 4, the conveying block 16 can be limited.

[0029] The main problem solved by this embodiment is that: by setting up a drilling assembly, the inclined surface of the transported punch body 7 can be drilled, and the drilling assembly can also constrain the storage plate 5 after jacking to prevent slippage, so that the subsequent drilling is more stable. By setting up a connection device, the power transmission can be released after the punch body 7 is transported to the inside of the drilling assembly, and the clamping assembly and the positioning device are triggered to position the punch body 7 and the conveying block 16. Positioning the punch body 7 can prevent shaking during subsequent drilling, and positioning the conveying block 16 can prevent the conveying block 16 from sliding when processing the punch body 7, causing the punch body 7 to be displaced. The punch body 7 can be limited by setting the clamping assembly to make the punch body 7 more firm. The positioning device can be set to position the transmission block 16 to prevent shaking and facilitate the reset of the subsequent connection assembly. Under the combined movement of the above-mentioned mechanisms, the current problem of using a vise to clamp and position the punch when processing the inclined surfaces on both sides of the punch is solved. This positioning method requires each punch to be recalibrated and positioned during processing, which is very inconvenient for operators when processing it and will affect the processing efficiency. Working principle: When the device is in motion, the action sequence of the lifting rod 39, the hexagonal rod 27, the pressure rod 23, the limiting rod 28 and the push rod 34 is interrelated, and the specific interrelated motion modes are as follows: when the storage plate 5 slides into the interior of the fixed frame 8, the storage plate 5 is lifted upward under the action of the elastic force of the lifting spring 41, and the rectangular block 44 is driven to slide upward, so that the bottom of the rectangular block 44 slides out from the limiting cavity 43. At this time, the driving sleeve 19 and the conveying block 16 are in a state of being released from the constraints, and the driving sleeve 19 and the conveying block 16 can rotate relative to each other. At the same time, when the lifting rod 39 slides upward, the first copper sheet 45 and the second copper sheet 46 are separated from each other, so that the motor 14 stops working; At the same time, when the storage plate 5 slides upward, the hexagonal rod 27 will slide upward. At this time, the inclined surface of the inner bottom surface of the wedge-shaped opening 29 will push the pressing rod 23 to one side when sliding upward, so that one end of the pressing rod 23 slides into the storage groove 20 to press the male mold body 7. When the limit rod 28 slides upward, the limit on the fixed plate 36 will be released. At this time, the rectangular block 44 also slides upward. Under the push of the inclined surface of the rectangular block 44, the push rod 34 drives the rubber block 32 to slide into the conveying groove 4 until one side of the rubber block 32 is in contact with the inner wall of the conveying groove 4, so that the conveying block 16 can be limited. The device can instantly and synchronously position the punch body 7 and the transmission block 16 while releasing the power transmission, avoiding the problem of motion deviation of mechanical parts in the gap of electrical signal transmission caused by using electric push rods or hydraulic cylinders, which need to receive electrical signals to trigger the action. The device adopts mechanical structures such as these rods, which can make multiple combined parts move synchronously, thereby improving the sensitivity of mechanical transmission. For example, in one embodiment, the present invention further provides a method for processing a convex inclined hole, which is applied to a convex inclined hole processing device as described above, and comprises the following steps: Step S1: The punch body 7 is placed on the storage plate 5, and the motor 14 drives the screw rod 12 to rotate, so as to push the conveying block 16 into the drilling assembly. After entering the drilling assembly, the connection assembly is triggered to release the power transmission of the screw rod 12 to the conveying block 16, and the positioning device is triggered to position the conveying block 16. At the same time, the pressing assembly is also triggered to press the punch body 7, and then the drilling machine 9 inside the drilling assembly is operated to drill the punch body 7; Step S2: When the drilling assembly is working, the punch body 7 can be drilled by the drilling machine 9. When the trigger plate 5 rises and slides into the fixed frame 8, it is blocked by the limit plate 13, and at the same time, the contact switch 18 is pressed to turn on the indicator light 11 and the nozzle 17, which is used to prompt people to start the drilling operation and lubricate the punch body 7 to facilitate drilling; Step S3: When the connection device is working, after the punch body 7 is transported into the drilling assembly, the bottom of the rectangular block 44 is slid out of the limiting cavity 43, so that the power transmission can be released, and the clamping assembly and the positioning device are triggered to position the punch body 7 and the transmission block 16; Step S4: When the pressing assembly is working, the storage plate 5 will slide upwards, driving the hexagonal rod 27 to slide upwards.
