Description

Technical Field

[0001] This utility model relates to the field of flange shaft production and processing technology, specifically a grinding device for flange shaft production. Background Technology

[0002] Flange shafts are widely used in machinery, automobiles, aerospace and industrial equipment. They are a type of shaft part with a flange. If the flange mounting surface and shaft mounting surface of the flange shaft are too rough, it will lead to unstable connection and sealing failure. Therefore, grinding equipment is often required during the production of flange shafts.

[0003] Current grinding equipment for flange shaft production often requires grinding the flange mounting surface and the outer diameter mounting surface of the shaft one by one. This results in low grinding efficiency and makes it difficult to achieve one-time grinding and shaping of the flange shaft mounting surfaces. To address this, we propose a new type of grinding equipment for flange shaft production, which improves the processing effect. Utility Model Content

[0004] The purpose of this invention is to provide a grinding device for flange shaft production, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a grinding device for flange shaft production, comprising a frame, a PLC controller mounted on the outer wall of the frame, a drive housing uniformly fixed at the top of the frame, a stepper motor mounted at the top of the drive housing, a drive gear connected to the output end of the stepper motor, a laser positioner mounted at the top of the drive gear, a laser emitter matching the laser positioner mounted on the inner wall of the drive housing, a driven gear meshing with the drive gear movably connected inside the drive housing, telescopic cylinders fixed at both ends of the top of the driven gear, a clamping block connected to the output end of the telescopic cylinder, a pressure sensing plate mounted on the clamping block, side grinding parts for shafts and lower grinding parts for flanges respectively mounted at both ends of the frame, connecting arms matching the frame fixed on both the side grinding parts for shafts and the lower grinding parts for flanges, a dust collection box mounted at the bottom of the frame, a dust removal fan mounted on one side of the dust collection box, and a main exhaust pipe mounted on the other side of the dust collection box.

[0006] Preferably, there are two drive housings, and the drive housings are hollow.

[0007] Preferably, the driven gear has a hollow structure, and a hollow bearing connected to the drive housing is provided at the bottom edge of the driven gear. The top and bottom of the drive housing are provided with openings that match the driven gear.

[0008] Preferably, one end of the connecting arm is provided with an assembly slide bar, and the frame is provided with an assembly slide groove that is slidably connected to the assembly slide bar.

[0009] Preferably, the outer side wall of the frame is fixed with a hydraulic telescopic cylinder that matches the assembly slide.

[0010] Preferably, the output end of the hydraulic telescopic cylinder is equipped with a locking block that presses against the mounting slide bar.

[0011] Preferably, both ends of the top of the main exhaust pipe are threadedly connected to dust removal branch pipes that match the drive housing, and there are two of each of the drive housing and the dust removal branch pipes.

[0012] Preferably, a filter cloth layer is installed inside the dust collection box on the side near the dust removal fan by screws.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] (1) The grinding device for flange shaft production optimizes its performance by installing a lower grinding component for flanges. On the one hand, starting the stepper motor can drive the drive gear to rotate, which in turn drives the driven gear meshing with the drive gear to rotate. This enables the flange shaft product fixed inside the driven gear to rotate. When the product rotates, the outer surface of the upper part of the shaft will continuously rub against the side grinding component for shafts, achieving grinding of the outer surface of the shaft and improving the flatness of the shaft mounting surface. At the same time, the lower surface of the flange of the flange shaft product will continuously rub against the lower grinding component for flanges, achieving grinding of the lower surface of the flange and improving the performance of the flange shaft. The flatness of the flange mounting surface allows the device to perform comprehensive grinding of both the shaft and flange mounting surfaces of the flange shaft in one operation, improving work efficiency. On the other hand, by adding a laser positioner to the drive gear and installing a matching laser emitter on the inner wall of the drive housing, each time the laser positioner receives a signal emitted by the laser emitter, it indicates that the drive gear has rotated one revolution. This allows the PLC controller to control the number of revolutions of the drive gear to regulate the number of revolutions of the flange shaft driven by the driven gear, thus facilitating precise control of the number of grinding revolutions. This is beneficial for standardized grinding control and improves processing quality.

[0015] (2) The grinding device for flange shaft production is equipped with telescopic cylinders, which optimizes the structure of the device. On the one hand, the user can pass the shaft of the flange shaft product upward through the driven gear, and then start the telescopic cylinder fixed at both ends of the driven gear. The clamping and fixing block at its output end clamps and fixes the flange shaft product. The clamping pressure can be monitored and fed back in real time by the pressure sensing plate installed on the clamping and fixing block. This makes it easy for the PLC controller to intelligently control the clamping force of the product and avoid the situation of being too loose or too tight. On the other hand, the user can use the sliding connection structure formed between the assembly slide and the assembly slide to position and assemble the connecting arm set on the shaft side grinding part and the flange lower grinding part on the frame. Then, the user can start the hydraulic telescopic cylinder to make the locking block at its output end extend into the assembly slide to press the assembly slide to achieve fast and automatic locking and fixing. This makes it easy for the device to select the appropriate specifications of the shaft side grinding part and the flange lower grinding part according to the specific flange shaft product and achieve quick installation and disassembly on the frame, which improves the flexibility.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0023] Please see Figure 1-5 An embodiment of this utility model provides a grinding device for flange shaft production, including a frame 1, a PLC controller 6 installed on the outer wall of the frame 1, a drive housing 3 uniformly fixed at the top inside the frame 1, a stepper motor 5 installed at the top of the drive housing 3, a drive gear 10 connected to the output end of the stepper motor 5, a laser positioner 12 installed at the top of the drive gear 10, and a laser emitter 11 matching the laser positioner 12 installed on the inner wall of the drive housing 3.

[0024] The drive housing 3 is internally connected to a driven gear 8 that meshes with the drive gear 10. Both ends of the top of the driven gear 8 are fixed with telescopic cylinders 9. The output end of the telescopic cylinder 9 is connected to a clamping block 14. A pressure sensing plate 13 is installed on the clamping block 14.

[0025] There are two drive housings 3, and the drive housing 3 has a hollow structure;

[0026] The driven gear 8 has a hollow structure. A hollow bearing connected to the drive housing 3 is provided at the bottom edge of the driven gear 8. The top and bottom of the drive housing 3 are provided with openings that match the driven gear 8.

[0027] In use, the user can pass the shaft of the flange shaft product upward through the driven gear 8, and then activate the telescopic cylinder 9 fixed at both ends of the top of the driven gear 8. The flange shaft product is clamped and fixed through the clamping and fixing block 14 at its output end. The clamping pressure can be monitored and fed back in real time through the pressure sensing plate 13 installed on the clamping and fixing block 14. This makes it easy for the PLC controller 6 to intelligently control the clamping force of the product and avoid the situation of being too loose or too tight. In specific grinding processes;

[0028] The two ends of the frame 1 are respectively equipped with a side grinding part 2 for shaft and a lower grinding part 21 for flange. Both the side grinding part 2 for shaft and the lower grinding part 21 for flange are fixed with a connecting arm 22 that matches the frame 1. One end of the connecting arm 22 is provided with an assembly slide 19, and the frame 1 is provided with an assembly slide groove 20 that is slidably connected to the assembly slide 19.

[0029] A hydraulic telescopic cylinder 4 that matches the assembly slide 20 is fixed to the outer side wall of the frame 1;

[0030] The output end of the hydraulic telescopic cylinder 4 is equipped with a locking block 18 that presses against the mounting slide bar 19;

[0031] In use, the user can use the sliding connection structure formed between the assembly slide bar 19 and the assembly slide groove 20 to position and assemble the connecting arm 22 on the shaft side grinding part 2 and the flange lower grinding part 21 on the frame 1. Then, the hydraulic telescopic cylinder 4 is activated so that the locking block 18 at its output end extends into the assembly slide groove 20 to press the assembly slide bar 19 to achieve quick and automatic locking and fixing. This makes it easy to select the appropriate specifications of the shaft side grinding part 2 and the flange lower grinding part 21 on the frame 1 according to the specific flange shaft product to achieve quick installation and disassembly, thus improving flexibility.

[0032] Both ends of the top of the main exhaust pipe 15 are threadedly connected to dust removal branch pipes 16 that match the drive housing 3. Both the drive housing 3 and the dust removal branch pipes 16 are provided with two.

[0033] A filter cloth layer is installed inside the dust collection box 7 on the side near the dust removal fan 17 by screws;

[0034] A dust collection box 7 is installed at the bottom inside the frame 1. A dust removal fan 17 is installed on one side of the dust collection box 7, and a main exhaust pipe 15 is installed on the other side of the dust collection box 7.

[0035] When in use, the dust removal fan 17 is started, which can extract the gas inside the dust collection box 7, so that the dust collection box 7 has a negative pressure. Then, through the main exhaust pipe 15 and the dust removal branch pipe 16 at the top, the debris generated by the product being polished inside the two drive housings 3 is promptly extracted and discharged, which makes the device achieve a good dust removal and protection effect.

[0036] In use, this embodiment of the application is powered by an external power source. The user can pass the shaft of the flange shaft upward through the driven gear 8, and then activate the telescopic cylinder 9 fixed at both ends of the top of the driven gear 8. The clamping and fixing block 14 at its output end clamps and fixes the flange shaft. The pressure sensor 13 installed on the clamping and fixing block 14 can monitor and provide feedback on the clamping pressure in real time. This facilitates the PLC controller 6 to intelligently control the clamping force of the product, avoiding situations where it is too loose or too tight. At the same time, the user can use the sliding connection structure formed between the assembly slide bar 19 and the assembly slide groove 20 to connect the connecting arm 2 on the side grinding part 2 for the shaft and the lower grinding part 21 for the flange. 2. Positioning and assembly are performed on frame 1. Then, the hydraulic telescopic cylinder 4 is activated, causing the locking block 18 at its output end to extend inside the assembly slide groove 20 and press against the assembly slide strip 19 to achieve rapid and automated locking and fixing. This allows the device to easily select the appropriate specifications of the shaft side grinding part 2 and flange lower grinding part 21 for positioning and quick installation and removal on frame 1 according to the specific flange shaft product, improving flexibility. Furthermore, starting the stepper motor 5 can drive the drive gear 10 to rotate, which in turn drives the driven gear 8 meshing with the drive gear 10 to rotate. This enables the flange shaft product fixed inside the driven gear 8 to rotate. When the product rotates, its upper shaft part... The outer cylindrical surface continuously rubs against the side grinding component 2 of the shaft, achieving grinding of the outer cylindrical surface of the shaft and improving the flatness of the shaft mounting surface. Simultaneously, the lower surface of the flange of the flange shaft continuously rubs against the lower grinding component 21 of the flange, achieving grinding of the lower surface of the flange and improving the flatness of the flange mounting surface. This allows the device to perform comprehensive grinding of both the shaft and flange mounting surfaces of the flange shaft in one operation, improving work efficiency. Furthermore, by adding a laser positioner 12 to the drive gear 10 and installing a laser emitter 11 matching the laser positioner 12 on the inner wall of the drive housing 3, the laser positioner 12 receives a laser pulse each time... The signal emitted by the laser emitter 11 indicates that the drive gear 10 has rotated one revolution. This allows the PLC controller 6 to control the number of revolutions of the drive gear 8 to rotate the flange shaft by controlling the number of revolutions of the drive gear 10. This facilitates precise control of the number of grinding revolutions, which is beneficial for standardized grinding control and improves processing quality. In addition, the dust removal fan 17 is started, which can extract the gas inside the dust collection box 7, creating a negative pressure inside the dust collection box 7. Then, through the main exhaust pipe 15 and the dust removal branch pipe 16 at the top, the debris generated by the product being ground inside the two drive housings 3 is promptly extracted and discharged. This makes the device achieve a good dust removal and protection effect.
