Description

Technical Field

[0001] This application relates to the field of workpiece polishing technology, and in particular to an automatic workpiece polishing device. Background Technology

[0002] After parts are machined by CNC machining centers, their surfaces will have a layer of fine cutting marks. For parts with high precision requirements, these cutting marks can seriously affect their use. Therefore, it is necessary to mirror polish the parts to remove the cutting marks.

[0003] In existing technologies, to shorten the polishing time and improve the efficiency of workpiece processing, a polishing machine is often used. A typical polishing machine mainly consists of a frame with a hinged door. Inside the frame is a chamber for placing the workpiece, and inside the chamber is a drive mechanism for moving the blasting head. When sandblasting larger workpieces, operators often need to use tools such as an electric hoist to pre-lift the workpiece into the chamber, place it inside, close the door, and then control the sandblasting machine and drive mechanism together via the control panel on the frame. The drive mechanism propels the sandblasting machine along a set path across the surface of the workpiece, polishing and grinding it.

[0004] However, after the workpiece is polished, the operator needs to open the chamber door to take the workpiece out. There is a lot of dust in the chamber, which causes great harm to the operator's health. There is room for improvement. Utility Model Content

[0005] To improve the ease of use of the control cabinet, this application provides an automatic workpiece polishing device.

[0006] The automatic workpiece polishing device provided in this application adopts the following technical solution:

[0007] An automatic workpiece polishing device includes a frame, on which a plurality of dust removal pipes are fixedly installed. A plurality of exhaust ports are formed on the inner wall of a chamber within the frame. The inlet ends of the dust removal pipes are respectively connected to the exhaust ports. A baffle is fixedly installed on the inner wall of the chamber, and the baffle has a plurality of filter holes, covering the exhaust ports.

[0008] The position detection module is fixedly installed on the inner wall of the chamber and is connected to the signal output terminal of the control panel on the frame. It is used to detect the position of the sandblasting head in the chamber and output the first control signal after the sandblasting head completes the grinding process.

[0009] A fan is fixedly installed on the frame and connected to the outlet end of several dust removal pipes. The outlet end is connected to a dust collector. The signal input end is connected to the signal input end of the position detection module to receive the first control signal and operate.

[0010] The prompting module is fixedly installed on the rack, and its signal input terminal is connected to the signal output terminal of the position detection module. It is used to issue a prompt after receiving the first control signal for a set time.

[0011] The signal output terminal of the prompting module is connected to the signal input terminal of the fan and the dust collector.

[0012] By adopting the above technical solution, during the actual production and processing, the operator can place large workpieces into the chamber using an electric hoist, ensuring the workpiece's surface to be polished faces upwards. Then, a start signal is input through the control panel. Upon receiving the start signal, the position detection module activates, detecting the position of the sandblasting head. The drive mechanism then drives the sandblasting head along a set path past the processing surface and resets. When the sandblasting head returns to its initial position, the position detection module outputs a first control signal. Upon receiving this signal, the fan and dust collector activate, drawing in dust-laden air from the chamber, purifying it, and discharging it into the indoor exhaust system. When the fan and dust collector have run for the set duration, a prompting module alerts the operator that the dust-laden air in the chamber has been completely expelled. Simultaneously, the fan and dust collector stop, prompting the operator to open the chamber door and remove the workpiece. This achieves the technical effect of automatically detecting the position of the sandblasting head and automatically removing dust-laden air from the chamber after sandblasting and polishing, effectively reducing the amount of dust inhaled by the operator when opening the chamber door.

[0013] Preferably, the position detection module includes:

[0014] An ultrasonic ranging sensor is fixedly installed on the inner wall of the chamber. Its signal input terminal is connected to the signal output terminal of the control panel. It is used to detect the distance between the sensor and the sandblasting head and output a sensing distance signal.

[0015] The comparator chip has its signal input terminal connected to the signal output terminal of the ultrasonic ranging sensor. It is used to receive the sensing distance signal and output a high-level signal when the sensing distance reaches a set value.

[0016] The first microcontroller has its signal input terminal connected to the signal output terminal of the ultrasonic ranging sensor, and is used to receive the high-level signal and output the first control signal when the high-level signal lasts for a set duration.

[0017] The signal input terminal of the ultrasonic ranging sensor is connected to the signal output terminal of the first microcontroller. The ultrasonic ranging sensor receives the first control signal and stops operating.

[0018] By adopting the above technical solution, when the sandblasting head is reset, the sensing distance measured by the ultrasonic ranging sensor remains constant, the comparator chip continuously outputs a high-level signal, the first microcontroller calculates the duration of the high-level signal to calculate the duration after the sandblasting head is reset, and outputs the first control signal after the sandblasting head is reset for the set duration. The fan and dust collector can run automatically upon receiving the first control signal, achieving the effect of automatically starting the fan and dust collector; at the same time, the ultrasonic ranging sensor stops running after receiving the first control signal, and can be automatically turned off.

[0019] Preferably, the exhaust end of the fan is connected to an exhaust pipe, the outlet end of the exhaust pipe is connected to the dust collector, and the exhaust end of the dust collector is connected to the indoor exhaust gas emission system.

[0020] By adopting the above technical solution, the connection between the fan and the dust collector can be realized through the exhaust pipe, so that the air containing powder drawn out by the fan can be purified by the dust collector.

[0021] Preferably, the prompting module includes:

[0022] A timer is connected to the signal output terminal of the first microcontroller and is used to receive the first control signal and output the dust removal time signal.

[0023] The second microcontroller has its signal input terminal connected to the signal output terminal of the timer, and is used to receive the dust removal time signal and output a second control signal when the dust removal time reaches the set duration.

[0024] An indicator light is fixedly installed on the outer wall of the frame, and its signal input terminal is connected to the signal output terminal of the second microcontroller to receive the second control signal and emit light.

[0025] The signal input terminals of the timer, the fan, and the dust collector are connected to the signal output terminal of the second microcontroller. The timer, the fan, and the dust collector receive the second control signal and stop operating.

[0026] By adopting the above technical solution, the running time of the fan and dust collector can be detected through the combination and use of the timer, the second microcontroller and the indicator light. When the running time of the fan and dust collector reaches the set time, the second microcontroller controls the indicator light to light up, and at the same time controls the fan, timer and dust collector to stop running. The fan, dust collector and timer can be automatically shut down, and the indicator light will prompt the operator to open the silo door.

[0027] Preferably, a cantilever mounting bracket is fixedly installed on the side wall of the frame, and the control panel is fixedly installed on the cantilever mounting bracket.

[0028] By adopting the above technical solution and using a cantilever mounting bracket, the control panel can be installed.

[0029] In summary, the automatic workpiece polishing device of this application has at least one of the following beneficial technical effects:

[0030] 1. When the sandblasting head is reset, the sensing distance measured by the ultrasonic ranging sensor remains constant, and the comparator chip continuously outputs a high-level signal. The first microcontroller calculates the duration of the high-level signal to calculate the duration after the sandblasting head is reset, and outputs the first control signal after the sandblasting head is reset for the set duration. The fan and dust collector can automatically run upon receiving the first control signal, thus achieving the effect of automatically starting the fan and dust collector.

[0031] 2. By using the timer, the second microcontroller, and the indicator lights in combination, the running time of the fan and dust collector can be detected. When the running time of the fan and dust collector reaches the set time, the second microcontroller controls the indicator lights to light up, and at the same time controls the fan, timer, and dust collector to stop running. The fan, dust collector, and timer can be automatically shut down, and the indicator lights will prompt the operator to open the silo door. Attached Figure Description

[0036] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0037] Example

[0038] This application discloses an automatic workpiece polishing device. (Refer to...) Figures 1-3It mainly includes a frame 1, on which several dust removal pipes 2 are fixedly installed. Several exhaust ports 11 are opened on the inner wall of the chamber 13 of the frame 1. The inlet ends of several dust removal pipes 2 are respectively connected to several exhaust ports 11. A baffle 12 is fixedly installed on the inner wall of the chamber 13. Several filter holes are opened on the baffle 12, and the baffle 12 covers several exhaust ports 11.

[0039] In addition: a position detection module, fixedly installed on the inner wall of the chamber 13, connected to the signal output terminal of the control panel 15 on the frame 1, used to detect the position of the sandblasting head in the chamber 13 and output a first control signal after the sandblasting head completes the grinding process; a fan, fixedly installed on the frame 1, connected to the outlet end of several dust removal pipes 2, with the outlet end connected to a dust collector 3, and its signal input terminal connected to the signal input terminal of the position detection module, used to receive the first control signal and operate; a prompting module, fixedly installed on the frame 1, with its signal input terminal connected to the signal output terminal of the position detection module, used to issue a prompt after receiving the first control signal for a set time; the signal output terminal of the prompting module is connected to the signal input terminals of the fan and the dust collector 3.

[0040] During actual production and processing, the operator can use an electric hoist to place large workpieces into chamber 13, ensuring the workpiece's surface to be polished faces upwards. Then, a start signal is input through control panel 15. Upon receiving the start signal, the position detection module activates, detecting the position of the sandblasting head. The drive mechanism then drives the sandblasting head along a set path past the processing surface and resets it. When the sandblasting head returns to its initial position, the position detection module outputs a first control signal. Upon receiving this signal, the fan and dust collector 3 activate, drawing in dust-laden air from chamber 13, purifying it, and discharging it into the indoor exhaust system. When the fan and dust collector 3 have run for the set duration, a prompting module alerts the operator that the dust-laden air in chamber 13 has been completely expelled. Simultaneously, the fan and dust collector 3 stop operating, prompting the operator to open chamber door 14 and remove the workpiece from chamber 13. This technology automatically detects the position of the sandblasting head and automatically removes dust-laden air from chamber 13 after sandblasting and polishing, effectively reducing the amount of dust inhaled by the operator when opening chamber door 14.

[0041] Among them, the dust collector 3 is the prior art, and the dust collector 3 is a bag dust collector of model DS-101. In some other embodiments, other models of dust collector 3 may be used according to actual needs, which will not be limited or described here.

[0042] Reference Figure 1 and Figure 2The position detection module includes: an ultrasonic ranging sensor 4, fixedly installed on the inner wall of the chamber 13, with its signal input terminal connected to the signal output terminal of the control panel 15, used to detect the distance between itself and the sandblasting head and output a sensing distance signal; a comparator chip, with its signal input terminal connected to the signal output terminal of the ultrasonic ranging sensor 4, used to receive the sensing distance signal and output a high-level signal when the sensing distance reaches a set value; and a first microcontroller, with its signal input terminal connected to the signal output terminal of the ultrasonic ranging sensor 4, used to receive the high-level signal and output a first control signal when the duration of the high-level signal reaches a set duration; the ultrasonic ranging sensor 4 is connected to the signal output terminal of the first microcontroller, and the ultrasonic ranging sensor 4 receives the first control signal and stops operating.

[0043] When the sandblasting head is reset, the sensing distance measured by the ultrasonic ranging sensor 4 remains constant, and the comparator chip continuously outputs a high-level signal. The first microcontroller calculates the duration of the high-level signal to calculate the duration after the sandblasting head is reset, and outputs the first control signal after the sandblasting head is reset for the set duration. The fan and dust collector 3 can run automatically after receiving the first control signal, thus achieving the effect of automatically starting the fan and dust collector 3. At the same time, the ultrasonic ranging sensor 4 stops running after receiving the first control signal, and can be automatically turned off.

[0044] It should be noted that in this embodiment, the fan is fixedly installed on the rear side of the polishing frame 1, and the exhaust end of the fan is connected to an exhaust pipe 5. The outlet end of the exhaust pipe 5 is connected to the dust collector 3, and the exhaust end of the dust collector 3 is connected to the indoor exhaust gas emission system.

[0045] The exhaust pipe 5 allows for connection between the fan and the dust collector 3, enabling the air containing powder drawn out by the fan to be purified by the dust collector 3.

[0046] Reference Figure 3 The prompting module includes: a timer, which is connected to the signal output terminal of the first microcontroller to receive the first control signal and output a dust removal time signal; a second microcontroller, whose signal input terminal is connected to the signal output terminal of the timer to receive the dust removal time signal and output a second control signal when the dust removal time reaches the set duration; an indicator light 6, which is fixedly installed on the outer wall of the frame 1, whose signal input terminal is connected to the signal output terminal of the second microcontroller to receive the second control signal and emit light; and the signal input terminals of the timer, fan, and dust collector 3 are connected to the signal output terminal of the second microcontroller, and the timer, fan, and dust collector 3 receive the second control signal and stop running.

[0047] By using the timer, the second microcontroller, and the indicator light 6 together, the running time of the fan and dust collector 3 can be detected. When the running time of the fan and dust collector 3 reaches the set time, the second microcontroller controls the indicator light 6 to light up, and at the same time controls the fan, timer, and dust collector 3 to stop running. The fan, dust collector 3, and timer can be automatically shut down, and the indicator light 6 will prompt the operator to open the hopper door 14.

[0048] Reference Figure 1 A cantilever mounting bracket 7 is fixedly installed on the side wall of the frame 1, and the control panel 15 is fixedly installed on the cantilever mounting bracket 7. The control panel 15 can be installed through the cantilever mounting bracket 7.

[0049] The implementation principle of the automatic workpiece polishing device in this application embodiment is as follows: During actual production and processing, the operator can place a large workpiece into the chamber 13 using an electric hoist, ensuring the workpiece's surface to be polished faces upwards. Then, a start signal is input through the control panel 15. Upon receiving the start signal, the position detection module starts, detecting the position of the sandblasting head. The drive mechanism drives the sandblasting head along a set path past the processing surface and then resets it. When the sandblasting head returns to its initial position, the position detection module outputs a first control signal, and the fan and dust collector 3 start upon receiving the first control signal. The dust-laden air in chamber 13 is drawn in, purified, and then discharged into the indoor exhaust system. When the fan and dust collector 3 have been running for a set time, the prompt module alerts the operator that the dust-laden air in chamber 13 has been completely discharged. At the same time, the fan and dust collector 3 stop running, prompting the operator to open the chamber door 14 and remove the workpiece from chamber 13. This technology can automatically detect the position of the sandblasting head and automatically remove the dust-laden air in chamber 13 after sandblasting and polishing, effectively reducing the amount of dust inhaled by the operator when opening the chamber door 14.

[0050] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
