Description

Technical Field

[0001] The invention belongs to the technical field of surface grinders, and in particular relates to an adjustable manual precision surface grinder. Background Art

[0002] Manual precision surface grinder is a surface grinder manual process suitable for batch processing. It can grind various planes and shapes through adsorption or special fixtures. It is suitable for processing precision small parts, mold inserts and medical devices. It mainly uses the periphery of the grinding wheel to grind various materials such as steel, cast iron and non-ferrous metals. During the grinding process of the grinder, splash grinding materials in a directional spark state will be generated between the grinding wheel and the upper surface of the material to be ground. At this time, the surface temperature of the splash grinding materials can reach 600-900℃, so it is necessary to install a cooling water pipe on the grinding wheel side, and spray cooling water through the cooling water pipe to cool the grinding wheel and the workpiece to be ground. If the splash grinding materials after cooling are not cleaned in time, they will solidify on the grinding wheel outer cover, baffle plate and upper surface of the grinding machine body.

[0003] For example, a Chinese patent with announcement number CN216421970U discloses a surface grinder for precision machining, including a base and a bottom box, the bottom of the base is connected to the bottom box, the upper left end of the base is connected to a studio, the middle of the inner bottom end of the studio is connected to a workbench, the upper right end of the base is connected to a control panel, a protective box is installed at the top of the inner top of the studio, a ball screw is horizontally arranged inside the protective box, a guide opening is opened at the bottom of the protective box, a nut seat is installed on the nut of the ball screw, and the lower end of the nut seat passes through the guide opening of the protective box and is connected to the external support The support plate is connected, the lower left end of the support plate is connected with a telescopic cylinder, the lower end of the telescopic cylinder is connected with a fixed block, a rotating motor is installed in the middle of the bottom of the fixed block, the lower end of the rotating motor is connected with a coupling, the lower end of the coupling is connected with a grinding tool, the right end of the ball screw is connected with a driven wheel, the driven wheel passes through the top of the studio through a belt and is connected to the external driving wheel, the axis of the driving wheel is connected to the output shaft of the power motor at the right end; by setting two baffle plates, it can effectively prevent the grinding waste from splashing everywhere, which is convenient for cleaning the grinding waste later.

[0004] However, the above scheme has the following shortcomings: in the above patent document, the splashing grinding material is collected by two fixedly installed material baffles, but for different specifications and types of materials to be ground, the splashing grinding material in the state of Mars is thrown out at different distances, and the installation position of the material baffle is fixed, and it cannot be adaptively adjusted according to the throwing range of the splashing grinding material and the distance between the grinding wheels. At the same time, the grinding material splashed onto the material baffle cannot be cleaned up in the first time. How to facilitate the adaptive adjustment of the distance between the material baffle and the grinding wheel while timely cleaning the splashing grinding material that is about to solidify on the material baffle is a problem that needs to be solved now.

The left side of the scraper frame 6 has the same curvature as the inner side of the baffle plate 4, and the right side of the scraper frame 6 is parallel to the upper and lower end surfaces of the frame box 5. The transmission motor 7 is a 5IK60RGU-CF-5GU7.5K speed-regulating motor produced by Guizhou Yutian Motor Co., Ltd. The specifications and models of the transmission motor 7 are adaptively adjusted according to the size of the baffle plate 4. A bearing hole is preset on the side wall of the scraper frame 6. The output shaft end of the transmission motor 7 is interference-pierced through the inner ring of the bearing hole and is detachably fixed to the scraper frame 6. The output shaft end of the transmission motor 7 drives the scraper frame 6 to rotate along the inner side of the baffle plate 4.

[0029] A suction cone cover 8 extending to the inner area of ​​the baffle plate 4 is fixedly inserted into the inner side of the opening of the frame box 5. The suction cone cover 8 is inserted into the inner side of the frame box 5. Figure 5 The connecting rod shown is detachably fixed on the inner rear wall of the frame box 5, and the connecting part of the connecting rod and the frame box 5 is located outside the rotation trajectory of the scraper frame 6, so that the fixed position design of the connecting rod will not affect the rotation movement of the scraper frame 6 around the suction cone cover 8. The suction cone cover 8 is a funnel-shaped structure, and the center line of the suction cone cover 8 and the horizontal line of the output shaft end of the transmission motor 7 are arranged to coincide with each other. The outer surface of the suction cone cover 8 is circumferentially embedded with a magnetic suction block 9, and the magnetic suction block 9 is arranged in four circumferential directions. The magnetic suction block 9 is a permanent magnet or an electromagnet block. When the electromagnet block is used, the power supply end of the electromagnet block is connected to the external power supply connected to the surface grinder body 1, and the control end of the electromagnet block is connected to the controller on the surface grinder body 1, so that the electromagnet block is closed for four seconds after running for ten seconds and then opened again. The four electromagnet blocks are opened and closed at staggered times to ensure that one electromagnet block is in working condition within ten seconds. At the same time, it is necessary to ensure that the output shaft end of the transmission motor 7 drives the scraper frame 6 to rotate one circle within four seconds. The magnetic suction block 9 is used to magnetically absorb and collect the splashing grinding material passing through, effectively reducing the amount of splashing grinding material leaking from the bottom of the frame box 5.

[0032] Embodiment three:

[0033] Further explanation is given on the basis of Example 1. The upper and lower ends of the frame box 5 are provided with grooves. The scraper rack 6 is set in two. The maximum opening of the suction cone cover 8 faces the bottom of the grinding wheel inside the grinding wheel outer cover 2. The scraper assembly includes a main scraper plate 14 arranged on the outer surface of the scraper rack 6. The outer surface of the main scraper plate 14 is sleeved with a 1 mm thick nylon layer to prevent the main scraper plate 14 from scratching the inner curved surface of the baffle plate 4. The main scraper plate 14 follows the rotation of the scraper rack 6 to scrape the splashed grinding material on the inner curved surface of the baffle plate 4 into the groove at the bottom of the frame box 5 for temporary collection.

[0034] The scraper assembly also includes an outer scraper plate 15 and an inner scraper plate 16 arranged on the upper and lower scraper frames 6. The outer scraper plate 15 and the inner scraper plate 16 are also covered with a 1mm thick nylon layer on their outer surfaces. The outer scraper plate 15 and the inner scraper plate 16 scrape the splashed grinding material attracted by the magnetic suction block 9 on the outer and inner surfaces of the suction cone cover 8 through the discharge port 10 into the groove at the bottom of the frame box 5;

[0035] The two side walls of the bottom groove of the frame box 5 are provided with drainage inclined mesh ports 17, the top groove of the frame box 5 is provided with a water distribution chamber box 18, the bottom end surface of the water distribution chamber box 18 is connected with a water nozzle 19, the cooling liquid sprayed by the water nozzle 19 can be in the form of any one of atomization and umbrella shape, the side of the surface grinder body 1 is screwed and fixed with a water pump body 20, the water pump body 20 is a TL-C01-C24-2411 cooling liquid pump produced by Changsha Duopule Pump Industry Technology Co., Ltd., the liquid inlet end of the water pump body 20 is connected to the liquid inlet side of the cooling liquid pipe 3 through a three-way valve, and the flow specification selection of the water pump body 20 will not affect the normal flow of the cooling liquid pipe 3, the premise is that the displacement of the cooling box corresponding to the cooling liquid pump is greater than the required drainage flow, and the liquid outlet side of the water pump body 20 and the water distribution chamber box 18 are connected by a guide The liquid pipe 21 is connected, and a pipe winding disk 101 is provided on the horizontal telescopic component. The pipe winding disk 101 can temporarily store the liquid guide pipe 21. The liquid guide pipe 21 is wound and inserted into the pipe winding disk 101. The water pump body 20 allows the sucked coolant to pass through the liquid guide pipe 21 and the water distribution chamber box 18 in sequence and be sprayed out from the water nozzle 19 end. The water nozzle 19 sprays the coolant to spray and cool the inner curved surface of the baffle plate 4 and the inner and outer surfaces of the suction cone cover 8 respectively, and the coolant discharged by the water nozzle 19 can clean the baffle plate 4 and the suction cone cover 8. At the same time, the drainage inclined mesh port 17 performs solid-liquid separation on the splashing grinding material collected at the bottom groove of the frame box 5 and the flowing coolant. At the same time, the flowing coolant can mix the splashing grinding material on the baffle plate 4 and the suction cone cover 8 and bring it to the drainage inclined mesh port 17 end for collection.

[0036] The working principle is as follows: during the use of the manual precision surface grinder body 1, the operator first installs and fixes the material to be ground on the grinding seat, and then adjusts the sleeve 11 and the sleeve plate column 12 to make the distance between the baffle plate 4 and the grinding wheel outer cover 2 as far as possible, connects the transmission motor 7 and the power end of the water pump body 20 to the external power socket, and the control end is connected to the controller part of the surface grinder body 1, and pre-grinds the material to be ground above the grinding seat by the grinding wheel on the surface grinder body 1, and manually operates the surface grinder body 1 to set the horizontal reciprocating motion distance of the grinding seat. After the setting is completed, the horizontal position of the baffle plate 4 is adjusted by adjusting the bolt 13, the sleeve plate column 12 and the adjusting sleeve 11, and the farthest moving distance between the frame box 5 and the material to be ground has a gap of 5 cm, so as to avoid collision between the material to be ground and the frame box 5, or the upper surface of the material to be ground is lower than the lower end surface of the frame box 5 by setting the grinding seat;

[0037] As the surface grinder body 1 is started, the transmission motor 7 and the water pump body 20 are started in turn. The splashing grinding materials generated by the grinding wheel and the grinding material to be ground will be thrown into the inner curved surface of the frame box 5 and the baffle plate 4 in turn under the action of centrifugal force, and the magnetic suction block 9 on the suction cone cover 8 can magnetically attract and guide the passing splashing grinding materials, reduce the amount of splashing grinding materials thrown out of the frame box 5, and improve the collection effect of the splashing grinding materials. The output shaft end of the transmission motor 7 drives the scraper frame 6 to rotate, and the water pump body 20 flushes the baffle plate 4 and the suction cone cover 8 through the liquid guide pipe 21 and the water nozzle 19, and the rotation of the scraper frame 6 drives the main scraper plate 14 and the outer scraper plate 1 5 and the inner scraper plate 16 rotate, thereby scraping and cleaning the splashing grinding materials on the inner curved surface of the baffle plate 4, the outer surface and the inner surface of the suction cone cover 8 respectively, and the splashing grinding materials on the suction cone cover 8 will be scraped into the bottom groove of the frame box 5 through the discharge port 10, and the splashing grinding materials and coolant flowing into the bottom groove of the frame box 5 will be separated into solid and liquid by the discharge inclined mesh port 17. After grinding, the operator only needs to clean the bottom groove of the frame box 5 uniformly, which is convenient for adaptively adjusting the distance between the baffle plate 4 and the grinding wheel, and can also timely clean the splashing grinding materials that are about to solidify on the baffle plate 4 and the suction cone cover 8.
