Description

Technical Field

[0001] The utility model relates to the technical field of resin grinding blocks, in particular to a resin grinding block which is conducive to chip removal. Background Art

[0002] Resin grinding blocks are a type of grinding material, usually made of resin binder, abrasive and filler. They are widely used in industrial fields such as machinery, chemical industry, metallurgy, light industry, building materials and electronics. Resin grinding blocks have high hardness, wear resistance, good toughness and impact resistance, and can be used to grind various hard materials such as metal, glass, ceramics and stone.

[0003] The patent document with application number 202223400333.2 discloses an elastic grinding block with a chip removal effect, including a top cover, an elastic grinding block and a fixing ring, the elastic grinding block includes an elastic base, a mounting block is provided on the top of the elastic base, a grinding head is provided at the bottom of the elastic base, a chip removal groove is provided at the bottom of the grinding head, holes are provided in the middle of the elastic base and the mounting block, the top cover includes an airbag, an air duct is provided at the bottom of the airbag, and the air duct outlet passes through the elastic base and the mounting block toward the chip removal groove.

[0004] However, traditional resin grinding blocks usually use the centrifugal force generated by the rotation of the grinding block itself to throw out some debris, and use the chip fluid to flush and cool the grinding block to help remove the debris. However, there are still some small debris that stubbornly adhere to the inner wall of the chip groove and cannot be quickly discharged with the chip fluid. This may cause a large amount of debris to accumulate in the chip groove for a long time, affecting the grinding effect of the grinding block, and may also cause an increase in cutting force during the cutting process, affecting the cutting efficiency, and even the retention of debris may cause vibration or instability during the cutting process, thereby affecting the accuracy and surface quality of the machined parts. Utility Model Content

[0005] The utility model discloses a resin grinding block which is conducive to chip removal, and aims to solve the problem that the traditional resin grinding block usually uses the centrifugal force generated when the grinding block rotates to throw out part of the debris, and helps to remove the debris when the grinding block is flushed and cooled by the chip liquid, but there are still some small debris stubbornly adhering to the inner wall of the chip groove and unable to be quickly discharged with the chip liquid, which may cause a large amount of debris to accumulate in the chip groove for a long time, affecting the grinding effect of the grinding block, and may also cause the cutting force to increase during the cutting process, affecting the cutting efficiency, and even the retention of debris may cause vibration or instability during the cutting process, thereby affecting the precision and surface quality of the processed parts.

[0006] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] A resin grinding block that is conducive to chip removal, comprising a grinding block base, a top cover is provided on the top outer wall of the grinding block base, a mounting base is provided on the top outer wall of the top cover, six grinding heads are provided at equal distances on the bottom outer wall of the grinding block base, and further comprising:

[0010] The above technical solution can improve cutting efficiency and avoid chip retention that affects cutting stability. Specifically, first install the mounting base on a grinder or polisher to ensure that it is firmly installed to prevent it from falling off or being damaged during work. Then make the grinding head contact the workpiece to perform grinding or polishing operations. When the ground chips slide through the inclined surface into the chip grooves between the grinding block bases, start the driving mechanism, which drives the connecting assembly to perform a circular linear reciprocating motion, thereby driving the guide plate to fold and shake, and then promote the discharge of the chips inside the chip groove. At the same time, during the grinding process, the cutting fluid can be used to flush the grinding block base to flush and discharge the chips in the chip groove, thereby improving the chip removal effect.

[0011] In a preferred embodiment, the connecting assembly includes six connecting frames, both ends of the connecting frames are fixedly connected with connecting rods, the outer walls of the connecting rods are sleeved with connecting blocks, the two ends of the connecting blocks are respectively fixedly connected to the outer walls of two adjacent guide plates, and the connecting rods are inserted into the inner walls of the connecting grooves, and both ends of the connecting rods and the connecting frames are located inside the mounting grooves.

[0012] When in use, the driving mechanism drives the connecting frame and the connecting rod to move back and forth in a straight line in the installation groove, similar to the working principle of an eccentric wheel, thereby driving the connecting block to move left and right, and then driving the guide plate to tilt left and right, increasing the friction on the debris in the chip discharge groove and promoting the discharge of the debris. The connecting groove is set to reserve a certain amount of moving space for the connecting rod to move left and right, and also to limit the connecting rod.

[0013] In a preferred embodiment, the driving mechanism includes a fixed plate and six gears, the six gears are meshed with each other, a motor is provided on the bottom outer wall of the fixed plate, one end of the output shaft of the motor is fixedly connected to one of the gears, a protrusion is provided on the bottom outer wall of the gear near the edge, one end of the connecting frame is installed on the circumferential outer wall of the protrusion, a mounting rod is provided at the center of the bottom outer wall of the fixed plate, a protective cover is provided on the end of the mounting rod away from the fixed plate, and five of the gears are connected to the top outer wall of the protective cover through bearings.

[0014] When in use, start the motor, and the output shaft of the motor drives one of the gears to rotate. Since the six gears are meshed with each other, the other five gears are driven to mesh with each other and rotate, so that the rotation of the gear drives the protrusion to rotate, and then drives the connecting frame to move back and forth in the installation groove, so that one power source can drive multiple connecting components to move back and forth at the same time, so as to quickly discharge the debris in the chip discharge groove and prevent the accumulation of debris.

[0015] As can be seen from the above, a resin grinding block that is conducive to chip removal includes a grinding block base, a top cover is provided on the top outer wall of the grinding block base, a mounting base is provided on the top outer wall of the top cover, and six grinding heads are distributed at equal distances on the bottom outer wall of the grinding block base, and also includes:

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. The components of the embodiments of the present application usually described and marked in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the application claimed for protection, but merely represents the selected embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present application.

[0024] The resin grinding block that is conducive to chip removal disclosed by the utility model is mainly used for traditional resin grinding blocks, which usually use the centrifugal force generated when the grinding block itself rotates to throw out part of the debris, and use the chip fluid to flush and cool the grinding block to help remove the debris. However, there are still some small debris that stubbornly adhere to the inner wall of the chip groove and cannot be quickly discharged with the chip fluid. This may cause a large amount of debris to accumulate in the chip groove for a long time, affecting the grinding effect of the grinding block, and may also cause the cutting force to increase during the cutting process, affecting the cutting efficiency, and even the retention of debris may cause vibration or instability during the cutting process, thereby affecting the accuracy and surface quality of the processed parts.

[0025] Reference Figure 1 , Figure 3 and Figure 4 A resin grinding block that is conducive to chip removal, comprising a grinding block base 3, a top cover 2 is provided on the top outer wall of the grinding block base 3, a mounting base 1 is provided on the top outer wall of the top cover 2, and six grinding heads 4 are equidistantly distributed on the bottom outer wall of the grinding block base 3, and further comprising:

[0026] Driving mechanism: located in the center of the outer wall of the bottom of the grinding block base 3;

[0027] Chip removal mechanism: located between two adjacent grinding heads 4, the chip removal mechanism includes six chip removal grooves 6, the inner walls on the opposite sides of the chip removal grooves 6 are provided with mounting grooves 17, the inner walls on one side of the mounting grooves 17 are provided with limit blocks 14, the interior of the limit blocks 14 is provided with connecting grooves, the outer walls on the opposite sides of the chip removal grooves 6 are hinged with seventeen guide plates 13, the bottom outer wall of the driving mechanism is provided with a connecting assembly, and the connecting assembly is installed between two adjacent guide plates 13.

[0028] Among them, the cross-sectional shape of the chip groove 6 is an arc structure, and the opening of the chip groove 6 gradually increases from the inside to the outside. The chip groove 6 is used to guide the chips generated during the cutting process to flow out, to avoid the chips from accumulating in the grinding block base 3 and affecting the grinding effect. The arc-shaped section of the chip groove 6 has a certain gathering effect on the debris, making it difficult for the debris to scatter, and it is convenient to cooperate with the connecting component to push the debris out.

[0029] Specifically, when in use, first install the mounting base 1 on a grinder or polisher to ensure that it is firmly installed to prevent it from falling off or being damaged during work, and then make the grinding head 4 contact the workpiece to perform grinding or polishing operations. When the ground chips slide through the inclined surface into the chip groove 6 between each grinding block base 3, start the driving mechanism, and the driving mechanism drives the connecting assembly to perform a circular linear reciprocating motion, thereby driving the guide plate 13 to fold and shake, and then promote the discharge of the chips inside the chip groove 6. At the same time, during the grinding process, the cutting fluid can also be used to flush the grinding block base 3 to flush and discharge the chips in the chip groove 6, thereby improving the chip removal effect.

[0030] Reference Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the connecting assembly includes six connecting frames 7, both ends of the connecting frames 7 are fixedly connected with connecting rods 15, the outer wall of the connecting rod 15 is sleeved with a connecting block 16, the two ends of the connecting block 16 are respectively fixedly connected to the outer walls of two adjacent guide plates 13, and the connecting rod 15 is inserted into the inner wall of the connecting groove, and both ends of the connecting rod 15 and the connecting frame 7 are located inside the mounting groove 17.

[0031] The connecting block 16 is a “T”-shaped structure, and the connecting block 16 of the “T”-shaped structure is convenient for connecting two guide plates 13 at the same time, so as to better control the deflection angle and movement direction of the guide plates 13 .

[0032] During the specific implementation process, the connecting frame 7 is a "U"-shaped structure. The "U"-shaped connecting frame 7 can drive the two connecting rods 15 to move at the same time, thereby driving the guide plates 13 on the inner walls on both sides of the chip groove 6 to discharge the debris at the same time, thereby enhancing the chip removal effect and avoiding the accumulation of debris, which affects the grinding effect of the grinding block base 3.

[0033] The height of the guide plate 13 is consistent with the height of the chip removal groove 6 .

[0034] Specifically, when in use, the driving mechanism drives the connecting frame 7 and the connecting rod 15 to move back and forth in a straight line in the installation groove 17, similar to the working principle of an eccentric wheel, thereby driving the connecting block 16 to move left and right, and then driving the guide plate 13 to tilt left and right, thereby increasing the friction on the debris in the chip discharge groove 6 and promoting the discharge of the debris. The connecting groove is set to reserve a certain amount of moving space for the connecting rod 15 to move left and right, and also to limit the connecting rod 15.

[0035] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 In a preferred embodiment, the driving mechanism includes a fixed plate 10 and six gears 9, which are meshed with each other. A motor 11 is provided on the bottom outer wall of the fixed plate 10, and one end of the output shaft of the motor 11 is fixedly connected to one of the gears 9. A protrusion 8 is provided on the bottom outer wall of the gear 9 near the edge, and one end of the connecting frame 7 is installed on the circumferential outer wall of the protrusion 8. A mounting rod 12 is provided at the center of the bottom outer wall of the fixed plate 10, and a protective cover 5 is provided at the end of the mounting rod 12 away from the fixed plate 10, wherein five gears 9 are connected to the top outer wall of the protective cover 5 through bearings.

[0036] Specifically, when in use, the motor 11 is started, and the output shaft of the motor 11 drives one of the gears 9 to rotate. Since the six gears 9 are meshed with each other, the other five gears 9 are driven to mesh with each other and rotate, so that the rotation of the gear 9 drives the protrusion 8 to rotate, and then drives the connecting frame 7 to reciprocate in the mounting groove 17, so that one power source can drive multiple connecting components to reciprocate at the same time, thereby quickly discharging the debris in the chip discharge groove 6 to prevent the accumulation of debris.

[0037] Working principle: When in use, first install the mounting base 1 on the grinder or polisher to ensure that it is firmly installed to prevent it from falling off or being damaged during work, and then make the grinding head 4 contact the workpiece to perform grinding or polishing operations. When the ground chips slide through the inclined surface into the chip groove 6 between each grinding block base 3, start the driving mechanism, and the driving mechanism drives the connecting assembly to perform a circular linear reciprocating motion, thereby driving the guide plate 13 to fold and shake, and then promote the discharge of the chips inside the chip groove 6. At the same time, during the grinding process, the cutting fluid can also be used to flush the grinding block base 3 to flush and discharge the chips in the chip groove 6, thereby improving the chip removal effect.
