Description

Technical Field

[0001] This utility model relates to the field of machining equipment technology, and in particular to a fully automatic drilling and tapping machine. Background Technology

[0002] In modern machining, drilling and tapping are the most common and critical machining processes in the manufacture of metal parts. Traditional machining methods typically require these processes to be completed on different equipment; for example, drilling is done on a drilling machine first, and then tapping is done on a tapping machine. This decentralized machining model has many drawbacks. First, frequent equipment changes lead to low machining efficiency. Each equipment change requires re-clamping the workpiece and adjusting machining parameters, increasing auxiliary time and reducing production efficiency. Second, multiple clamping can easily cause workpiece positioning errors, affecting machining accuracy. It is difficult to guarantee the consistency of machining accuracy between different machines, which in turn affects the overall quality of the parts. In addition, multi-machine processing increases the equipment footprint and investment costs. For enterprises, this not only requires purchasing multiple machines but also equipping them with corresponding operators and maintenance personnel, significantly increasing labor and equipment maintenance costs. Utility Model Content

[0003] To address the problems associated with decentralized processing, this utility model presents a fully automatic drilling and tapping integrated machine that combines drilling and tapping into one unit, enabling a single machine to complete multiple processing steps.

[0004] To solve the above-mentioned technical problems, this utility model provides a fully automatic drilling and tapping integrated machine, including a frame and a feeding device, a drilling device, a tapping device, a loading device, a unloading device, a detection device, and a control system for controlling the processing of each device, all mounted on the frame.

[0005] The frame is equipped with a multi-station indexing plate, and the feeding device, drilling device, detection device, tapping device and unloading device are arranged sequentially along the rotation direction of the multi-station indexing plate. The multi-station indexing plate is used to transfer workpieces between different devices.

[0006] The multi-station indexing plate has several processing stations evenly distributed along the circumference. Each processing station includes a first tooling and a clamping device. The first tooling has at least one first placement groove. The first placement groove has a first opening that extends radially outward and a second opening that extends vertically upward.

[0007] The workpiece is placed in or removed from the first placement slot through the first opening, and the second opening provides processing space for the workpiece; a set of clamping devices is provided for each first placement slot, and the clamping devices are used to clamp and fix the workpiece in the first placement slot;

[0008] The discharge end of the feeding device is connected to the loading device, and its inlet end is provided with a pre-drilling device; the workpiece includes a drilling position, and the pre-drilling device is used for pre-drilling on the reverse side of the drilling position.

[0009] When the pre-drilling device is used for processing, the drilling position is set with the reverse side facing upward; when the drilling device is used for processing, the drilling position is set with the front side facing upward; the feeding device includes a flipping channel, and when the workpiece passes through the feeding device, the flipping channel flips the drilling position so that the reverse side is facing upward and the front side is facing upward.

[0010] In a preferred embodiment, the clamping device includes a clamping frame and a first elastic element. The two legs of the clamping frame are movably mounted on the first tooling from bottom to top in the vertical direction. The two legs of the clamping frame are arranged opposite to each other on both sides of the first placement groove in the circumferential direction.

[0011] One end of the first elastic member is fixed to the bottom of the first tooling in the vertical direction, and the other end is fixed to the clamping frame. The first elastic member can push out of the clamping frame in the vertical direction. The end of the support leg away from the first elastic member extends upward out of the first tooling and is provided with a pressure head. The projection of the pressure head in the vertical direction is in the first placement groove.

[0012] When the clamping frame is ejected, the pressure head restricts it from moving downward away from the first tooling; under the ejection action of the first elastic element, the pressure head presses the workpiece vertically downward, and the workpiece is fixed in the first placement groove.

[0013] In a preferred embodiment, both the feeding device and the unloading device include a release device. The release device includes a first lifting cylinder and a pressure plate. The first lifting cylinder drives the pressure plate to move vertically up and down. The pressure plate is used to lift the clamping frame vertically upward, so that the legs of the clamping frame drive the pressure head to lift upward.

[0014] When the feeding device feeds the workpiece, the pressure head is raised upwards away from the first placement slot, making room for the first opening to place the workpiece; when the unloading device unloads the workpiece, the pressure head is raised upwards to release the workpiece, and the workpiece is released from the first placement slot through the first opening.

[0015] In a preferred embodiment, the first tooling includes a push rod arranged radially, and one push rod is provided for each of the first placement slots;

[0016] One end of the push rod passes through the first tooling and can extend into the first placement groove; the other end of the push rod is provided with a push block, and the rod body of the push rod is fitted with a second elastic element, the two ends of the second elastic element being fixed to the push block and the first tooling respectively;

[0017] The feeding device includes a discharge channel and a feeding pusher. The feeding pusher includes a feeding cylinder and a feeding component. The feeding cylinder drives the feeding component to move radially.

[0018] When the processing station corresponds to the discharge channel, the unloading cylinder drives the unloading component, the unloading component pushes the push block radially outward, the push block presses the second elastic element to push out the push rod, and the push rod pushes the workpiece in the first placement slot to the discharge channel;

[0019] When the feeding component moves radially inward, the push rod moves radially inward and exits the first placement slot under the action of the second elastic element.

[0020] In a preferred embodiment, the feeding device includes a support frame and a feeding assembly and a feeding pusher mounted on the support frame. The feeding assembly includes a second lifting cylinder and a second tooling. The second tooling has a through groove radially corresponding to the first placement groove.

[0021] The second lifting cylinder drives the second tooling to move vertically to have a first position and a second position; when the second tooling is in the first position, the through groove is connected to the discharge end of the feeding device, and the workpiece falls into the through groove from the discharge end; when the second tooling is in the second position, the through groove is connected to the first placement groove, and the workpiece is pushed from the through groove to the first placement groove by the feeding pusher.

[0022] In a preferred embodiment, the feeding device further includes a first sensor and a baffle plate, the baffle plate being positioned corresponding to the discharge end, and the first sensor being fixed on the baffle plate;

[0023] When the second tooling is in the first position, one side of the through groove is connected to the discharge end, and the other side is blocked by the baffle plate. The first sensor is used to detect whether the workpiece exists in the through groove.

[0024] In a preferred embodiment, the feeding pusher includes a feeding cylinder and a feeding component. The feeding cylinder drives the feeding component to move radially so that the feeding component can extend into or retract from the through groove.

[0025] When the second tooling is in the second position, one side of the through slot corresponds to the feeding component, and the other side of the through slot is connected to the first placement slot. The feeding cylinder drives the feeding component to push the workpiece toward the first placement slot.

[0026] In a preferred embodiment, the pre-drilling device includes a pre-drilling machine and a third tooling. The third tooling has an inlet and an outlet on both sides along the transport direction. The inlet and the outlet are offset from each other, and the outlet is connected to the inlet end of the feeding device.

[0027] The third tooling is provided with a slide groove perpendicular to the transport direction. A slider is slidably installed in the slide groove. The slider is provided with at least two second placement slots. The slider is driven by a drive cylinder to slide along the slide groove to change the position of the second placement slots.

[0028] One of the two second placement slots is connected to the inlet, and the workpiece is fed into the placement slot from the inlet. The other placement slot is connected to the outlet, and the workpiece is discharged from the outlet to the inlet.

[0029] In a preferred embodiment, a second sensor is provided on the side of the third tooling away from the feed inlet, and the position of the second sensor corresponds to the position of the feed inlet;

[0030] When one of the placement slots is connected to the inlet, the second sensor detects that the workpiece is in the placement slot and feeds back to the control system, which then controls the pre-drilling machining.

[0031] A pusher cylinder is provided on the side of the third tooling away from the discharge port, and the position of the pusher cylinder corresponds to the position of the discharge port. When one of the placement slots is connected to the discharge port, the telescopic rod of the pusher cylinder extends into the placement slot and pushes the workpiece to the inlet end.

[0032] In a preferred embodiment, the feeding device includes a feeding channel in a reverse S-shape, the upper end of the feeding channel being the inlet end and the lower end being the outlet end, with the inlet end being higher than the outlet end;

[0033] The flipping channel is set in the S-shaped middle section of the feeding channel; the flipping channel is set as a spiral channel.

[0034] Compared with the prior art, the technical solution of this utility model has the following beneficial effects:

[0035] 1. A fully automatic drilling and tapping integrated machine is provided, which can effectively reduce the number of workpiece clamping times, improve processing accuracy and efficiency, and at the same time reduce the equipment footprint and labor costs, thus meeting the demand for high-efficiency, high-precision, and low-cost processing equipment.

[0036] 2. By adding a pre-drilling device, pre-drilling is performed on the opposite side of the drilling position before drilling, removing burrs on the opposite side of the drilling position and avoiding the impact of burrs on the subsequent machining accuracy. Furthermore, the pre-drilling device removes burrs on the opposite side before drilling, making burr formation in a more controllable position during machining, reducing the difficulty and workload of subsequent deburring.

[0037] 3. By using the flipping channel, the drilling position of the workpiece can be flipped from the reverse side to the front side before processing, so that the workpiece can automatically complete the posture adjustment during the feeding process. This ensures that the burrs removed in the pre-drilling stage will not interfere with the subsequent drilling process, thus improving the automation level of the entire process.

[0057] refer to Figures 1-15 This embodiment provides a fully automatic drilling and tapping machine, which can automatically feed, pre-drill, drill, inspect, tap and unload workpiece 101. By integrating multiple functional devices, it achieves efficient and automated processing. At the same time, by optimizing the structural design, it improves processing efficiency and quality.

[0058] like Figure 1 The fully automatic drilling and tapping machine includes a frame 10 and a feeding device 2, a drilling device 6, a tapping device 8, a loading device 4, a unloading device 5, a detection device 7, and a control system for controlling the processing of each device, all mounted on the frame 10. The frame 10 is equipped with a multi-station indexing plate 1, and along the rotation direction of the multi-station indexing plate 1, a set of loading devices 4, two sets of drilling devices 6, a set of detection devices 7, two sets of tapping devices 8, and a set of unloading devices 5 are sequentially arranged (e.g., ...). Figure 2 ).

[0059] The specific structure is as follows:

[0060] The frame 10 serves as the basic framework of the equipment, supporting all processing devices and control systems.

[0061] like Figure 3The multi-station indexing plate 1 is used to transfer the workpiece 101 between different devices. The multi-station indexing plate 1 includes a rotating device, which drives the multi-station indexing plate 1 to realize the automatic switching of the workpiece 101 between different devices. Several processing stations 11 are evenly distributed along the circumference on the multi-station indexing plate 1. Eight processing stations 11 are set for each group of devices. An extra processing station 11 is set between the unloading device 5 and the loading device 4 as a waiting processing station 11 or a spare processing station 11. Therefore, a total of nine processing stations 11 are set on the multi-station indexing plate 1.

[0062] Each of the aforementioned processing stations 11 includes a first tooling 12 and a clamping device 13 (e.g., ...). Figure 4 The first tooling 12 has two first placement slots 121. Each first placement slot 121 has a first opening 122 extending radially outward and a second opening 123 extending vertically upward. The workpiece 101 is placed in or removed from the first placement slot 121 through the first opening 122. The second opening 123 provides processing space for the workpiece 101. Each first placement slot 121 corresponds to a set of clamping devices 13, which are used to clamp and fix the workpiece 101 within the first placement slot 121. The first tooling 12 and the clamping devices 13 are used to position and fix the workpiece 101, ensuring that the workpiece 101 does not shift during processing.

[0063] The discharge end 22 of the feeding device 2 is connected to the loading device 4, and its inlet end 23 is provided with a pre-drilling device 3; the workpiece 101 includes a drilling position 1011, and the pre-drilling device 3 is used for pre-drilling the reverse side of the drilling position 1011; during processing by the pre-drilling device 3, the reverse side of the drilling position 1011 is set upwards (e.g., Figure 14 During the drilling process by the drilling device 6, the drilling position 1011 is positioned with the front facing upwards (e.g., Figure 15 The feeding device 2 includes a flipping channel 24. When the workpiece 101 passes through the feeding device 2, the flipping channel 24 flips the drilled position 1011 from the reverse side to the front side.

[0064] The drilling device 6 includes a drilling power head for completing the drilling process. Two sets of drilling devices 6 are arranged adjacent to each other along the multi-station indexing plate 1, corresponding to two first placement slots 121. The left drilling device 6 corresponds to the left first placement slot 121, and the right drilling device 6 corresponds to the right first placement slot 121, so that two workpieces 101 can be processed simultaneously.

[0065] The detection device 7 includes a contact sensor (such as a probe), which is driven by a lifting device to measure the drilling status of the workpiece 101.

[0066] The tapping device 8 includes a tapping power head for thread machining. Corresponding to the drilling device 6, two sets of tapping devices 8 are similarly configured to simultaneously process two workpieces 101.

[0067] The feeding device 5 is used for feeding the workpiece 101.

[0068] The control system employs a PLC or CNC system to achieve automated control of the equipment and adjustment of processing parameters. Position sensors are installed on each device to identify whether the processing station 11 has rotated into position when the multi-station indexing plate 1 rotates to switch processing stations 11, thus enabling the corresponding device to be driven for processing.

[0069] In this embodiment, the clamping device 13 includes a clamping frame 131 and a first elastic member 134 (e.g., ...). Figure 3 , Figure 4 The clamping frame 131 has two legs 132 that are movably mounted on the first tooling 12 from bottom to top in the vertical direction. The two legs 132 are arranged opposite each other on both sides of the first placement groove 121 in the circumferential direction. One end of the first elastic member 134 is fixed to the bottom of the first tooling 12 in the vertical direction, and the other end is fixed to the clamping frame 131. The first elastic member 134 can push the clamping frame 131 out vertically downward. The end of the leg 132 away from the first elastic member 134 extends upward from the first tooling 12 and is provided with a pressure head 133. The projection of the pressure head 133 in the vertical direction is in the first placement groove 121.

[0070] The pressure head 133 limits the support legs 132 of the clamping frame 131. When the clamping frame 131 is pushed out, the pressure head 133 is engaged with the first tooling 12, preventing the clamping frame 131 from continuing to detach downwards from the first tooling 12. Under the pushing action of the first elastic member 134, the clamping frame 131 always provides a downward force from the pressure head 133, so that the pressure head 133 presses the workpiece 101 vertically downwards (e.g., ...). Figure 4 The workpiece 101 is fixed in the first placement groove 121. The pressure head 133 vertically fixes the workpiece 101 to ensure that the workpiece 101 does not move when the drilling device 6 and the tapping device 8 process vertically downwards.

[0071] In this embodiment, both the feeding device 4 and the unloading device 5 include a release device 9 (e.g., Figure 4The release device 9 is located below the multi-station indexing plate 1. The release device 9 includes a first lifting cylinder 91 and a pressure plate 92. The first lifting cylinder 91 drives the pressure plate 92 to rise and fall vertically. The pressure plate 92 is used to lift the clamping frame 131 vertically upward, so that the support legs 132 of the clamping frame 131 drive the pressure head 133 to lift upward. When the loading device 4 loads the material, the pressure head 133 is lifted upward away from the first placement groove 121, making room for the first opening 122 for the placement of the workpiece 101. When the unloading device 5 unloads the material, the pressure head 133 is lifted upward to release the workpiece 101, and the workpiece 101 is released from the first placement groove 121 through the first opening 122.

[0072] The feeding structure and operation of the feeding device 5 are as follows:

[0073] like Figure 5 The first tooling 12 includes a radially arranged push rod 124, and one push rod 124 is provided for each first placement slot 121; one end of the push rod 124 passes through the first tooling 12 and can extend into the first placement slot 121; the other end of the push rod 124 is provided with a push block 125, and the rod body of the push rod 124 is fitted with a second elastic element 126, and the two ends of the second elastic element 126 are respectively fixed on the push block 125 and the first tooling 12; the feeding device 5 includes a discharge channel 51 and a feeding pusher 52, and the feeding pusher 52 includes a feeding cylinder 521 and a feeding component 522, and the feeding cylinder 521 drives the feeding component 522 to move radially.

[0074] When the processing station 11 corresponds to the discharge channel 51, the release device 9 is activated, the pressure head 133 is lifted upward to release the workpiece 101, and then the unloading cylinder 521 drives the unloading component 522. The unloading component 522 pushes the push block 125 radially outward. The push block 125 presses the second elastic element 126 to push out the push rod 124. The push rod 124 pushes the workpiece 101 in the first placement groove 121 to the discharge channel 51, completing the unloading of the workpiece 101.

[0075] After workpiece 101 is unloaded, the unloading cylinder 521 drives the unloading component 522 to return radially inward for the next unloading operation. After the unloading component 522 moves radially inward, the push rod 124 moves radially inward under the action of the second elastic element 126 and exits the first placement groove 121, so that the first placement groove 121 is empty and can be used for the next loading process. At the same time, the release device 9 resets, the pressure plate 92 descends vertically and retracts, the clamping frame 131 is pushed vertically downward again by the first elastic element 134, and the pressure head 133 presses downward on the edge of the first placement groove 121.

[0076] The feeding structure and operation of the feeding device 4 are as follows:

[0077] like Figure 7 The feeding device 4 includes a support frame 41 and a feeding assembly 42 and a feeding pusher 43 mounted on the support frame 41. The feeding assembly 42 includes a second lifting cylinder 421 and a second tooling 422. The second tooling 422 has a through groove 423 radially corresponding to the first placement groove 121 (e.g., Figure 9 The second lifting cylinder 421 drives the second tooling 422 to move vertically to have a first position and a second position. When the second tooling 422 is in the first position, the through groove 423 connects to the discharge end 22 of the feeding device 2, and the workpiece 101 falls into the through groove 423 from the discharge end 22. When the second tooling 422 is in the second position, the through groove 423 connects to the first placement groove 121, and the workpiece 101 is pushed from the through groove 423 to the first placement groove 121 by the feeding pusher 43 (e.g., Figure 8 ).

[0078] To facilitate the loading and transfer of workpiece 101, the loading device 4 also includes a first sensor 44 and a baffle plate 45 (e.g., ...). Figure 9-10 The baffle plate 45 is positioned corresponding to the discharge end 22, and the first sensor 44 is fixed on the baffle plate 45. When the second tooling 422 is in the first position, one side of the through groove 423 is connected to the discharge end 22, and the other side is blocked by the baffle plate 45. The position of the first sensor 44 corresponds to the position of one side of the through groove 423. The first sensor 44 is used to detect whether the workpiece 101 exists in the through groove 423.

[0079] The feeding device 2 and the loading device 4 load the workpiece as follows: the second lifting cylinder 421 drives the second tooling 422 to move vertically upward to the first position. The through slot 423 of the second tooling 422 connects to the discharge end 22 of the feeding device 2. The workpiece 101 is transported into the through slot 423 by the feeding device 2. The baffle plate 45 prevents the workpiece 101 from falling out from the other side of the through slot 423, ensuring that the workpiece 101 falls into the through slot 423. When the first sensor 44 detects that a workpiece 101 has been placed in the through slot 423, the first sensor 44 feeds back to the control system, which activates the second lifting cylinder 421 to drive the second tooling 422 to move vertically downward to the second position for loading into the first placement slot 121.

[0080] like Figure 8The feeding pusher 43 includes a feeding cylinder 431 and a feeding component 432. The feeding cylinder 431 drives the feeding component 432 to move radially, so that the feeding component 432 can extend into or retract from the through groove 423; when the second tooling 422 is in the second position (e.g. Figure 7 The through groove 423 has one side opening corresponding to the feeding component 432, and its other side opening is connected to the first placement groove 121. The feeding cylinder 431 drives the feeding component 432 to push the workpiece 101 toward the first placement groove 121.

[0081] like Figure 7 The feeding device 4 feeds the workpiece 101 into the first placement slot 121 as follows: When the second tooling 422 is in the second position, the feeding cylinder 431 drives the feeding component 432 to move radially toward the through slot 423. The feeding component 432 extends into the through slot 423, pushing the workpiece 101 located in the through slot 423 toward the first placement slot 121 until the workpiece 101 falls into the first placement slot 121, completing the feeding of the workpiece 101. During the feeding process, the pressure plate 92 of the release device 9 lifts the pressure head 133 upward, providing sufficient space for the first placement slot 121 to feed the workpiece 101. After feeding is completed, the first lifting cylinder 91 drives the pressure plate 92 downward, and the pressure head 133 presses down on the workpiece 101, fixing the workpiece 101 in the first placement slot 121.

[0082] In this embodiment, the pre-drilling device 3 includes a pre-drilling machine 31 and a third tooling 32 (such as...). Figure 11-12 The third tooling 32 has an inlet 321 and an outlet 322 on both sides along the transport direction. The inlet 321 and the outlet 322 are staggered. The outlet 322 is connected to the inlet end 23 of the feeding device 2.

[0083] like Figure 13 The third tooling 32 is provided with a slide groove 323 perpendicular to the transport direction. A slider 33 is slidably installed in the slide groove 323. The slider 33 has at least two second placement slots 331. The slider 33 is driven by a drive cylinder 34 to slide along the slide groove 323 to change the position of the second placement slots 331. One of the two second placement slots 331 is connected to the feed port 321, and the workpiece 101 is fed into the placement slot from the feed port 321. The other placement slot is connected to the discharge port 322, and the workpiece 101 is discharged from the discharge port 322 to the feed end 23.

[0084] The third tooling 32 has a second sensor mounting position 35 on the side away from the feed inlet 321 (e.g., Figure 13A second sensor is installed at the second sensor mounting position 35, and the position of the second sensor corresponds to the position of the feed port 321. When one of the placement slots is connected to the feed port 321, the second sensor detects that the workpiece 101 is in the placement slot and feeds back to the control system. The control system controls the pre-drilling machine 31 to process the workpiece.

[0085] The third tooling 32 is provided with a pusher cylinder 36 on the side away from the discharge port 322 (e.g., Figure 12 The position of the pusher cylinder 36 corresponds to the position of the discharge port 322; when one of the placement slots is connected to the discharge port 322, the telescopic rod of the pusher cylinder 36 extends into the placement slot and pushes the workpiece 101 to the inlet end 23.

[0086] The operation of the pre-drilling device 3 is as follows: corresponding to the two first placement slots 121 on the first tooling 12, two discharge ports 322 are opened on the third tooling 32, connecting the two sets of feeding devices 2 to realize the transportation of workpieces 101 in the two first placement slots 121. The pre-drilling device 3 is set as a set, and the processing position of the pre-drilling hole corresponds to the position of the inlet 321. The workpiece 101 is transported by vibration by the vibratory plate and enters the second placement slot 331 on the third tooling 32 through the inlet 321. In this embodiment, the slider 33 is provided with two second placement slots 331, corresponding to one inlet 321 and two discharge ports 322. The slider 33 has a first position and a second position under the drive of the drive cylinder 34, and the two discharge ports 322 are set on both sides of one inlet 321.

[0087] When performing pre-drilling, slider 33 slides to a position (e.g.) Figure 13 The second placement groove 331 on the left side is connected to the left discharge port 322, and the second placement groove 331 on the right side is connected to the feed port 321. The workpiece 10 is fed by the vibrating plate 20 (vibrating plate 20 is as follows). Figure 6 (As shown) Vibration transport to the second placement slot 331 on the right (as shown) Figure 12 The second sensor detects and provides feedback, driving the pre-drilling device 3 to start the pre-drilling process. After pre-drilling, the slider 33 slides to position two, with the left second placement groove 331 aligning with the feed inlet 321 and the right second placement groove 331 aligning with the right discharge outlet 322. The left second placement groove 331 continues to feed and pre-drill the workpiece 101, while the workpiece 101, which has already been pre-drilled, is pushed out to the feeding device 2 for unloading and transport by the pushing cylinder 36. The slider 33 slides back and forth, and the workpiece 101, after pre-drilling, is alternately unloaded at the two discharge outlets 322, thus completing the pre-drilling process.

[0088] In this embodiment, the feeding device 2 includes a feeding channel 21 in a reverse S-shape (e.g., Figure 6 The upper end of the feeding channel 21 is the inlet end 23, and the lower end is the outlet end 22, with the inlet end 23 being higher than the outlet end 22; the S-shaped middle section of the feeding channel 21 is provided with the flipping channel 24; the flipping channel 24 is configured as a spiral channel (e.g., Figure 11 The workpiece 101 is flipped through the spiral channel.

[0089] When the workpiece 101 is unloaded through the feeding channel 21, the height difference gives it the kinetic energy to fall from a high position to a low position. This kinetic energy allows the workpiece 101 to move smoothly along the S-shaped channel without the need for an additional power unit. The workpiece 101 moves along a curved path in the reverse S-shaped feeding channel 21. When the workpiece 101 passes through the spiral channel, the spiral design of the flipping channel 24 causes the workpiece 101 to gradually change its posture during movement, flipping from reverse side to front side. After flipping, the workpiece 101 continues to slide down the S-shaped channel and finally reaches the discharge end 22.

[0090] The above description is only a preferred embodiment of the present utility model, but the design concept of the present utility model is not limited thereto. Any non-substantial modifications made to the present utility model by those skilled in the art within the scope of the technology disclosed in the present utility model using this concept shall be deemed as an infringement of the protection scope of the present utility model.
