Description

Technical Field

[0001] This utility model relates to the field of blower processing technology, and in particular to a centrifugal blower volute processing device. Background Technology

[0002] With the continuous development of society and the continuous improvement of technology, more and more mechanical equipment is being applied to industrial, agricultural and other fields. Currently, blowers are commonly used in industrial fields. Blowers are mainly composed of motors, air filters, blower bodies, air chambers, bases (which also serve as oil tanks), oil drip nozzles, volutes and other components. When the blower is working, it relies on the eccentric rotation of the offset rotor inside the cylinder, and the volume change between the blades in the rotor slots to draw in, compress and expel air. Currently, centrifugal blowers are the most commonly used in industry. When manufacturing blowers, the end face of the blower housing, i.e., the volute, needs to be ground to ensure the smoothness of the housing surface. During the grinding process, the volute is usually clamped by a clamping structure. The upper end is set on the grinding structure, and the grinding structure is raised and lowered to achieve grinding of the volute. However, during the clamping process, the volute is often not fixedly clamped, making it inconvenient to adjust the angle of the volute. Grinding can only be achieved by moving the grinding device. Because the movement of the grinding device is limited, the volute often needs to be repeatedly clamped and fixed to achieve overall grinding, which greatly reduces the grinding efficiency. To address the above problems, a solution is proposed below. Utility Model Content

[0003] The purpose of this invention is to provide a centrifugal blower volute processing device to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A centrifugal blower volute processing device includes a processing box and a processing plate. The processing plate is rotatably mounted on the inner bottom wall of the processing box. A drive assembly for rotating the processing plate is provided between the processing box and the processing plate. Two fixed blocks are slidably mounted on the top of the processing plate. A push assembly for sliding the two fixed blocks is provided on the processing plate. Two electric slide rails are symmetrically mounted on the inner top wall of the processing box. A sliding plate is slidably mounted on each of the two electric slide rails. An electric slide rail is also mounted on the bottom of the two sliding plates. A sliding plate is also slidably mounted on the electric slide rail. A connecting plate is mounted on the sliding plate. An electric push rod is mounted on the bottom of the connecting plate.

[0007] Preferably, an annular groove is provided on the inner bottom wall of the processing box, and multiple sets of rollers are installed on the bottom of the processing plate. The processing plate is rotated and positioned in the annular groove by the rollers.

[0008] Preferably, the pushing assembly includes a double-ended screw, two sliders, and a third drive motor. A wide slot is provided on the top of the processing plate. The double-ended screw is rotatably disposed in the wide slot. The third drive motor is fixed on the side wall of the processing plate. The output shaft of the third drive motor passes through the processing plate and is fixedly connected to the double-ended screw. The two sliders are slidably disposed on both sides of the wide slot. The two sliders are threadedly engaged with both ends of the double-ended screw. The fixing block is fixed to the top of the sliders by bolts.

[0009] Preferably, the top of the processing plate is provided with multiple chip removal grooves, which are arranged at an inclination. The higher part of the chip removal groove is connected to the second wide groove, and the lower part of the chip removal groove penetrates the outer wall of the processing plate.

[0019] See Figures 1 to 6 As shown, a centrifugal blower volute processing device includes a processing box 1 and a processing plate 2. The processing plate 2 is rotatably mounted on the inner bottom wall of the processing box 1. Two fixed blocks 4 are slidably mounted on the top of the processing plate 2. The processing plate 2 is provided with a pushing component 5 for driving the two fixed blocks 4 to slide. When the volute needs to be surface polished, the volute can be placed on the processing plate 2 first. By activating the pushing component 5, the pushing component 5 can drive the two fixed blocks 4 to move, thereby clamping and fixing the volute through the fixed blocks 4.

[0020] The pushing assembly 5 includes a double-ended screw 51, two sliders 52, and a drive motor 53. A wide slot 54 is provided on the top of the processing plate 2. The double-ended screw 51 is rotatably mounted within the wide slot 54. The drive motor 53 is fixed to the side wall of the processing plate 2. The output shaft of the drive motor 53 passes through the processing plate 2 and is fixedly connected to the double-ended screw 51. The two sliders 52 are slidably mounted on both sides of the wide slot 54, and are threadedly engaged with both ends of the double-ended screw 51. A fixing block 4 is fixed to the top of the sliders 52 by bolts. When it is necessary to move the fixing block 4, the drive motor 53 can be started first. 3. The output shaft of the drive motor 53 drives the double-ended screw 51 to rotate. The double-ended screw 51 can drive the slider 52, which is threaded with it, to slide in the wide groove 54. The slider 52 is limited by the wide groove 54. The slider 52 transforms the rotational engagement with the double-ended screw 51 into a sliding engagement through the wide groove 54. The movement of the slider 52 can drive the top fixing block 4 to move. The fixing block 4 clamps the volute. The shape of the fixing block 4 can be freely selected according to the shape of the volute. The height of the fixing block 4 is less than the height of the volute, which facilitates the subsequent grinding of the volute.

[0021] The top of the processing plate 2 is also provided with multiple chip removal grooves 55. The chip removal grooves 55 are set at an inclination. The high part of the chip removal grooves 55 is connected to the second wide groove 54, and the low part of the chip removal grooves 55 penetrates the outer wall of the processing plate 2. During the grinding process of the volute, a lot of chips are generated. Some of the chips will remain in the second wide groove 54, which will affect the operation of the double-headed screw 51 in the second wide groove 54. Therefore, multiple chip removal grooves 55 connected to the second wide groove 54 are opened on the processing plate 2. The chip removal grooves 55 facilitate the subsequent cleaning of the waste chips in the second wide groove 54. The outer wall of the third drive motor 53 is also equipped with a protective box. By installing a protective box on the outside of the third drive motor 53, the third drive motor 53 can be protected.

[0022] Two electric slide rails 6 are symmetrically installed on the inner top wall of the processing box 1. Slide plates 7 are slidably mounted on both electric slide rails 6. Electric slide rails 8 are also installed at the bottom of the two slide plates 7, and slide plates 9 are slidably mounted on the electric slide rails 8. A connecting plate 10 is installed on the slide plate 9, and an electric push rod 11 is installed at the bottom of the connecting plate 10. A mounting bracket 12 is installed on the telescopic rod of the electric push rod 11, and a drive motor 13 is installed at the bottom of the mounting bracket 12. A connecting rod 14 is installed on the output shaft of the drive motor 13, and a grinding disc 15 is installed at the end of the connecting rod 14 away from the drive motor 13. After the volute is clamped, the electric slide rails 6 can be started. The two electric slide rails 6 are linked and start synchronously. The electric slide rails 6 can drive the slide plates 7 to slide. The first 7 can drive the second electric slide rail 8 to move. When the second electric slide rail 8 moves to the designated position, the second electric slide rail 8 can be activated again. The second electric slide rail 8 can drive the second slide plate 9 to move. The second slide plate 9 can indirectly drive the grinding disc 15 to move to the designated position. Through the setting of the first electric slide rail 6 and the second electric slide rail 8, the grinding disc 15 can be moved back and forth and left and right. When the grinding disc 15 corresponds with the worm gear 31, the second drive motor 13 can be activated first. The second drive motor 13 drives the connecting rod 14 to rotate. The connecting rod 14 drives the grinding disc 15 to rotate. At this time, the electric push rod 11 is activated. The electric push rod 11 can push the bottom mounting bracket 12 and the second drive motor 13 to lift and lower, thereby pushing the bottom grinding disc 15 to lift and lower, so that the grinding disc 15 can contact the worm housing for grinding.

[0023] A drive assembly 3 is provided between the processing box 1 and the processing plate 2 to drive the processing plate 2 to rotate. When the processing angle of the volute needs to be adjusted during the grinding process, the drive assembly 3 can be activated to drive the processing plate 2 to rotate. The processing plate 2 can drive the volute mounted on its top to rotate, thereby realizing the adjustment of the volute angle. This is more convenient and faster than the adjustment using electric slide rail 1 6 and electric slide rail 2 8.

[0024] The drive assembly 3 includes a worm gear 31, a worm 32, and a drive motor 33. A wide slot 34 is provided on the inner bottom wall of the processing box 1. The worm gear 31 is rotatably mounted at the bottom of the processing plate 2. The drive motor 33 is installed in the wide slot 34. The output shaft of the drive motor 33 is fixedly connected to the worm 32. The worm 32 is rotatably mounted in the wide slot 34 and meshes with the worm gear 31. The drive motor 33 is installed in the wide slot 34. The output shaft of the drive motor 33 is fixedly connected to the processing plate 2. When it is necessary to drive the processing plate 2 to rotate, the drive motor 33 can be started first. The output shaft of the drive motor 33 drives the worm 32 to rotate. The worm 32 can drive the worm gear 31 that meshes with it to rotate. Through the rotation of the worm gear 31, the rotation of the processing plate 2 is achieved, thereby realizing the adjustment of the worm housing angle without the need for repeated disassembly and reassembly of the worm housing.

[0025] An annular groove 35 is also provided on the inner bottom wall of the processing box 1. Multiple sets of rollers 36 are installed on the bottom of the processing plate 2. The processing plate 2 is rotatably set in the annular groove 35 by means of the rollers 36. When the processing plate 2 rotates, it will drive each roller 36 to rotate in the annular groove 35. The setting of the rollers 36 can support the processing plate 2 and reduce the friction generated when the processing plate 2 rotates.

[0026] The processing box 1 is also equipped with a filter assembly 16 for dust treatment. During the grinding process, the filter assembly 16 can be activated to treat the dust generated during grinding, thereby reducing dust pollution during the operation of the device. The filter assembly 16 includes a dust removal fan 161, two filter plates 162, and two collection frames 163. A dust removal chamber 164 is opened in the lower part of the processing box 1. A connecting groove 165 is opened on the top of both sides of the dust removal chamber 164, which communicates with the upper end of the processing box 1. The dust removal fan 161 is installed in the dust removal chamber 164, and the two filter plates 162 are respectively installed on both sides of the dust removal fan 161. The collection frames 163 are installed on the inner bottom wall of the dust removal chamber 164. The dust removal chamber 164 and the connecting groove 165 are connected. Corresponding to 65, an exhaust port is also provided in the dust removal chamber 164. During the filtration and dust removal process, the dust removal fan 161 can be started first. Two diversion pipes are installed at the air inlet of the dust removal fan 161. The two diversion pipes correspond to the filter plates 162 on both sides respectively. The dust removal fan 161 will generate a suction force. Through the suction force of the dust removal fan 161, the dust can be sucked into the dust removal chamber 164 through the connecting groove 165. The dust will be processed through the filter plates 162. The filtered gas is discharged through the exhaust port. A filter screen is also installed on the exhaust port to prevent external dust from entering the dust removal chamber 164. When the parts are processed, the dust removal fan 161 will not be started again. The dust can fall into the collection frame 163 by gravity for collection and processing.
