Description

Technical Field

[0001] The utility model relates to a hole opening device, in particular to a hole opening device for automatically detecting cutting materials. Background Art

[0002] In the current field of hole drilling in hollow plastic parts, the hole drilling device can only drill holes in hollow plastics; due to the lack of a reliable positioning mechanism, the following problems are likely to occur during the hole drilling process: 1. Large shaking is likely to occur during cutting, causing the cutting knife to break, and low accuracy in the hole cutting position; 2. It is difficult to detect whether the cut material has fallen into the product, and it can only rely entirely on manual visual inspection and removal, which greatly increases the labor intensity, low work efficiency, and leads to high labor costs. Utility Model Content

[0003] The purpose of the utility model is to provide a hole-opening device with simple structure, automatic detection and high working efficiency in view of the above problems. The hole-opening device can automatically detect whether the hole is in place and accurately detect whether the cut material is taken out, thereby preventing abnormal hole opening and the cut material from falling into the inside, greatly reducing the work intensity of employees and improving work efficiency.

[0004] The purpose of the utility model can be achieved by adopting the following technical solutions:

[0005] A hole-opening device for automatically detecting cutting materials comprises a frame, a driving device arranged on the frame, a positioning device and a cutting device fixedly mounted on the power output end of the driving device, a sensor arranged on the frame, and a detected mechanism slidably mounted on the power output end of the driving device; the detected mechanism comprises a limit block and a detected block, the limit block and the detected block are respectively arranged below and above the positioning device, and the limit block and the detected block are connected by a sliding rod; when the limit block is pressed upward by the product, the detected block slides upward, and the lower end of the positioning device extends out of the limit block and positions the cutting material; the cutting device cuts the product, and when the detected block slides upward to be detected by the sensor, the cutting device completes cutting the product, and the cutting material is positioned on the positioning device.

[0006] As a preferred solution, a discharge device is provided above the detected block. When the discharge device moves downward, the discharge device presses the detected block and the limit block to slide downward, and the limit block presses the cutting material downward to remove the cutting material from the positioning device.

[0007] As a preferred solution, the positioning device is a positioning needle, and the positioning needle is fixedly installed on the power output end of the driving device.

[0008] As a preferred solution, the sliding rod passes through the cutting device, and the sliding rod and the cutting device are movably connected.

[0009] As a preferred solution, the cutting device includes a mounting seat and a cutting knife fixedly mounted on the circumference of the mounting seat, and the mounting seat is fixedly mounted on the power output end of the driving device.

[0010] As a preferred solution, the unloading device includes a telescopic motor and a pressure plate fixedly mounted on the piston rod of the telescopic motor, and the pressure plate presses the detected block to remove the cut material from the positioning device.

[0011] As a preferred solution, the driving device includes a motor and a transmission shaft, the transmission shaft is fixedly mounted on the rotating shaft of the motor, and the positioning device and the cutting device are mounted on the transmission shaft.

[0013] As a preferred solution, the limit block and the detected block are made of metal materials.

[0014] The implementation of this utility model has the following beneficial effects:

[0015] 1. When drilling a hole in a product, the product moves upward under the drive of the top pressure mechanism and is pressed against the lower bottom surface of the limit block. The lower end of the positioning device gradually extends out of the lower bottom surface of the limit block and penetrates into the cutting material, so that the product is positioned on the positioning device. Then the cutting device cuts the product, and at the same time the limit block drives the detected block to slide upward. As the cutting depth continues to extend, when the detected block slides upward to be detected by the sensor, the cutting device completes the cutting of the product, and the cutting material is nailed to the lower end of the positioning device. In this process, the cutting material is nailed to the positioning device and will not fall into the product by itself. The entire opening automatic detection design is ingenious, with a simple structure, easy use and high work efficiency.

[0016] 2. When the cutting block needs to be removed from the positioning device, just start the unloading device to press the detected block, and let the detected block drive the limit block to move downward through the slide bar. Then the limit block presses the cutting material to make the cutting material escape from the lower end of the positioning device and fall, so that the cutting material can be controlled to fall to the desired position or container. The whole unloading process is extremely simple and convenient, which can better prevent the cutting material from falling automatically and realize controllable unloading.

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Example

[0025] Reference Figures 1 to 3, the present embodiment relates to a hole-opening device, comprising a frame 1, a driving device 2 arranged on the frame 1, a positioning device 3 and a cutting device 4 fixedly mounted on the power output end of the driving device 2, a sensor 5 arranged on the frame 1, and a detected mechanism 6 slidably mounted on the power output end of the driving device 2; the detected mechanism 6 comprises a limit block 61 and a detected block 62, the limit block 61 and the detected block 62 are respectively arranged below and above the positioning device 3, and the limit block 61 and the detected block 62 are connected by a sliding rod 63; when the limit block 61 is pressed upward by the product 100 and slides upward, the detected block 62 slides upward, and at the same time, the lower end of the positioning device 3 gradually extends out of the limit block 61 and positions the cutting material 101; then the cutting device 4 cuts the product 100; when the detected block 62 slides upward to be detected by the sensor 5, the cutting device 4 completes cutting the product 100, and the cutting material 101 is positioned on the positioning device 3.

[0026] When the product 100 is perforated, the product 100 moves upward under the drive of the top pressing mechanism and is pressed against the lower bottom surface of the limit block 61. The lower end of the positioning device 3 gradually extends out of the lower bottom surface of the limit block 61 and penetrates into the cutting material 101, so that the product is positioned on the positioning device. Then the cutting device 4 cuts the product 100, and the limit block 61 drives the detection block 62 to slide upward. As the cutting depth continues to extend, when the detection block 62 slides upward to be detected by the sensor 5, the cutting device 4 completes the cutting of the product 100, and the cutting material 101 is nailed to the lower end of the positioning device 3. In this process, the cutting material 101 is nailed to the positioning device 3 and will not fall into the interior of the product 100 by itself. If the cutting device 4 does not completely open the hole of the product 100, the limit block 61 presses against the cutting device 4 and cannot continue to rise, so that the sensor 5 cannot detect the detected block 62, indicating that the hole opening is abnormal; otherwise, it indicates that the hole opening is completed, thereby achieving accurate hole opening and preventing the problem of insufficient hole opening in the processed product 100. The entire hole opening automatic detection design is ingenious, simple in structure, easy to use and high in work efficiency.

[0027] like Figure 3 and Figure 4As shown, a discharge device 7 is provided above the detected block 62. When the discharge device 7 moves downward, the discharge device 7 presses the detected block 62 and the limit block 61 slides downward, and the limit block 61 presses the cutting material 101 downward to disengage the cutting material 101 from the positioning device 3. When the cutting block needs to be removed from the positioning device 3, it is only necessary to start the discharge device 7 to press the detected block 62, and let the detected block 62 drive the limit block 61 to move downward through the slide bar 63, and then the limit block 61 presses the cutting material 101 to disengage and fall from the lower end of the positioning device 3, so that the cutting material 101 can be controlled to fall to the desired position or container. The entire unloading process is extremely simple and convenient, which can better prevent the cutting material 101 from falling automatically and realize controllable unloading.

[0028] The positioning device 3 is a positioning needle, which is fixedly mounted on the power output end of the driving device 2. A through hole corresponding to the position of the positioning needle is opened on the limit block 61. As the product 100 presses the limit block 61 upward, the lower end of the positioning needle passes through the through hole and pierces into the cutting material 101.

[0029] The slide bar 63 passes through the cutting device 4, and the slide bar 63 is movably connected to the cutting device 4. The limit block 61 and the detected block 62 can slide in the vertical direction relative to the cutting device 4. When the product 100 presses the limit block 61 to slide upward, the limit block 61 drives the detected block 62 to slide upward through the slide bar 63.

[0030] The cutting device 4 includes a mounting seat 41 and a cutting blade 42 fixedly mounted on the circumference of the mounting seat 41. The mounting seat 41 is fixedly mounted on the power output end of the driving device 2. The slide bar 63 is slidably mounted on the mounting seat 41. The limit block 61 and the detected block 62 are fixedly mounted on the lower end and the upper end of the slide bar 63 respectively.

[0031] The unloading device 7 includes a telescopic motor 71 and a pressing plate 72 fixedly mounted on the piston rod of the telescopic motor 71 . The pressing plate 72 presses the detected block 62 to remove the cut material 101 from the positioning device 3 .

[0032] The driving device 2 includes a motor 21 and a transmission shaft 22, wherein the transmission shaft 22 is fixedly mounted on the rotating shaft of the motor 21, and the positioning device 3 and the cutting device 4 are mounted on the transmission shaft 22. The mounting seat 41 is fixedly mounted on the transmission shaft 22. The motor 21 drives the transmission shaft 22 to rotate, so that the transmission shaft 22 drives the positioning device 3, the cutting device 4 and the detected mechanism 6 to rotate.

[0033] The limiting block 61 and the detected block 62 are both circular in shape, and are made of metal.

[0034] The working principle of this utility model:

[0035] 1) The motor 21 outputs power to drive the transmission shaft 22 to rotate, so that the transmission shaft 22 drives the positioning needle, the limit block 61, the detected block 62 and the cutting device 4 to rotate.

[0036] 2) The pressing mechanism drives the product 100 to rise and press against the bottom surface of the limit block 61; the limit block 61 drives the detected block 62 to slide upward. As the product 100 presses the limit block 61 upward, the lower end of the positioning pin passes through the through hole and pierces the cutting material 101. Then the cutting device 4 cuts the product 100. When the detected block 62 slides upward to be detected by the sensor 5, the cutting device 4 completes the cutting of the product 100, and the cutting material 101 is nailed to the lower end of the positioning device 3.

[0037] 3) The pressing mechanism drives the product 100 to move downward and return to its original position. At this time, there are two opening situations: 1. Figure 3 As shown, the cutting material 101 is fixed on the positioning needle, and the detection sensor 5 detects the detected block 62, which indicates that the hole is opened normally and the device does not alarm; 2. Figure 5 As shown, the cut material 101 is not fixed on the positioning pin and falls into the interior of the product 100. At this time, the limit block 61 and the detected block 62 slide downward to the bottom position under the action of their own gravity; the sensor 5 cannot detect the detected block 62, and the equipment alarms at this time, and the next processing action cannot be performed.

[0038] 4) The telescopic motor 71 drives the pressing plate 72 to move downward and press the detected block 62. The detected block 62 drives the limit block 61 to move downward and press the cut material 101 downward, thereby removing the cut material 101 from the positioning device 3, so that the cut material 101 can be controlled to fall to the desired position or container. Then the telescopic motor 71 drives the pressing plate 72 back to its original position, completing the hole processing.

[0039] The above disclosure is only a preferred embodiment of the present invention, and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope covered by the present invention.
