Description

Technical Field

[0001] This utility model relates to the field of metal processing equipment technology, and in particular to an auxiliary tooling for grinding metal castings. Background Technology

[0002] Castings are metal shaped objects obtained by various casting methods. They are objects with a certain shape, size and properties obtained by pouring, injecting, sucking or other casting methods into a pre-prepared mold after smelting liquid metal, cooling and then processing them by grinding and other subsequent means.

[0003] After some long columnar metal castings are produced, they need to be cut according to actual needs. After the columnar metal castings are cut, burrs and flash will be left on the cut end face. In order to remove the burrs and flash, metal casting grinding equipment is generally used. This method is fast and efficient. However, most existing metal casting grinding equipment can only be used for castings of one specification. When processing columnar castings of different lengths and diameters, it is necessary to change and adjust the equipment. Utility Model Content

[0004] The technical problem to be solved by this utility model is that most existing grinding devices for columnar metal castings can only be applied to castings of one specification, and equipment needs to be changed when processing castings of different lengths and diameters.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows: This utility model provides an auxiliary tooling for grinding metal castings, including a clamping mechanism, a grinding mechanism, and a base. The clamping mechanism includes two clamping bases arranged opposite each other, the two clamping bases being "L"-shaped. Two roller support seats are fixedly installed on the clamping bases. A power roller is rotatably mounted on the roller support seats. One end of the power roller passes through the clamping base and is poweredly connected to a first rotating motor. The first rotating motor is fixedly installed at one end of the long side of the clamping base. Grinding grooves are opened on both sides of the long side of the clamping base. The grinding mechanism includes a first traveling motor, a grinding fixing block, a grinding motor, and a traveling truss. A traveling collar is fixedly installed on one side of the grinding fixing block. The power end of the grinding motor is fixedly connected to the traveling lead screw. The traveling lead screw is sleeved in the traveling collar. The traveling truss is "L" shaped. One end of the traveling lead screw is rotatably installed in the traveling truss through a bearing. The output end of the first traveling motor is poweredly connected to one end of the traveling lead screw. The grinding motor is fixedly installed on the grinding fixing block. A grinding wheel is installed on the output end of the grinding motor. The clamping mechanism is slidably installed on the base. Grinding mechanisms are slidably installed in both grinding grooves. The first traveling motor is fixedly installed on one side of the long side of both clamping bases. One end of the traveling truss is fixedly installed at the opening of the grinding groove.

[0006] Preferably, the traveling truss includes two parallel "L"-shaped truss plates. A push-pull plate is fixedly installed between the short sides of the two truss plates. One end of the traveling screw is rotatably mounted in the push-pull plate via a bearing. One end of the long side of each of the two truss plates is fixedly installed near the opening at the upper and lower ends of the grinding groove. A traveling guide rail is fixedly installed on the opposite side of the long side of the two truss plates. The grinding fixing block has a first sliding groove at both the upper and lower ends, and the grinding fixing block is slidably mounted on the traveling guide rail through the first sliding groove. The truss plates provide greater displacement space for the movement of the grinding fixing block, enabling the entire equipment to accommodate castings of more specifications. The push-pull plate serves to fix the traveling screw and also acts as a limit to prevent the grinding fixing block from derailing. The cooperation between the first sliding groove and the traveling guide rail reduces the friction of the grinding fixing block during movement, improves the accuracy of displacement, and also maintains the direction of movement to prevent it from deviating during movement.

[0007] Preferably, the grinding wheel includes a side grinding wheel and an end grinding wheel, with the side grinding wheel and end grinding wheel fixedly installed at the output ends of the two grinding motors, respectively. After cutting the casting, burrs and flash mainly appear at the intersection of the cut end face and the side face. Therefore, the side grinding wheel grinds the side face of the casting near the cut end, while the end grinding wheel grinds the cut end of the casting. Both the side grinding wheel and the end grinding wheel are replaceable.

[0008] Preferably, the base has a clamping groove at its top, and limit plates are provided at both ends of the clamping groove. A left-hand rotating screw is rotatably installed in the clamping groove. A motor mounting frame is fixedly installed on one side of the base, and a second travel motor is fixedly installed on the motor mounting frame. One end of the left-hand rotating screw passes through the limit plate and is poweredly connected to the output end of the second travel motor. A clamping collar is fixedly installed at the bottom of the short sides of the two clamping bases, and the two clamping collars are sleeved on the left-hand rotating screw. Two parallel clamping tracks are fixedly provided on the base, and the clamping groove is located between the two parallel clamping tracks. Two parallel clamping track grooves are opened at the bottom of the short sides of the two clamping bases, and the clamping collars are located between the two parallel clamping track grooves. The two clamping bases are slidably mounted on the clamping tracks through the clamping track grooves. The motor mounting frame is hollow inside. The output end of the second travel motor passes through the motor mounting frame, through the limiting plate, and is connected to one end of the left and right rotating screws. The second travel motor drives the left and right rotating screws to rotate. The two clamping bases move relative to each other through the clamping collars fixed at the bottom. The limiting plate can prevent the two clamping bases from disengaging from the clamping track. The cooperation between the clamping track and the clamping track groove can reduce friction and stabilize the direction of movement.

[0009] Preferably, a plurality of buffer mechanisms are provided on one long side of the clamping base. Each buffer mechanism includes two parallel buffer bases, and a buffer roller is rotatably arranged between the two buffer bases. The plurality of buffer mechanisms are arranged circumferentially, and the side of the buffer roller is in contact with the end face of the casting, which allows the casting to rotate more smoothly while ensuring stable clamping.

[0010] Preferably, a motor truss is fixedly installed on the grinding fixing block, the motor truss is sleeved on the first traveling motor, and the motor truss is slidably disposed in the grinding groove and the traveling truss. The first traveling motor is close to the casting, and the motor truss plays a role in protecting and fixing the first traveling motor.

[0011] The beneficial effects of this utility model are as follows: The rust removal brush of this utility model is replaceable. It clamps the casting through two relatively movable clamping bases, making the equipment applicable to castings of different lengths. The casting is driven to rotate by two power rollers, realizing the rotational grinding of the casting. The buffer rollers are in contact with the end face of the casting, ensuring stable clamping and smoother rotation of the casting. The end face and side face of the casting are ground by two sets of movable grinding mechanisms, making the equipment applicable to castings of different diameters. The entire device has a fast grinding speed, wide applicability, and can greatly improve production efficiency. Attached Figure Description

A push-pull plate 7 is fixedly installed between the short sides of the two truss plates 6. One end of the traveling screw 206 is rotatably mounted in the push-pull plate 7 via a bearing. One end of the long side of the two truss plates 6 is fixedly installed near the opening at the upper and lower ends of the grinding groove 4. A traveling guide rail 8 is fixedly installed on the opposite side of the long side of the two truss plates 6. The upper and lower ends of the grinding fixing block 202 are both provided with first sliding grooves 9.

[0027] In use, according to the specifications of the casting to be ground, the controller starts the second travel motor 14, which drives the left and right spiral screws 12 to rotate. The two clamping bases 101 sleeved on the left and right spiral screws 12 move relative to each other until they are adjusted to a suitable distance. External equipment transfers the casting between the two clamping bases 101, so that both ends of the casting are placed on the power rollers 103 of the two roller support seats 102 respectively. The sides of the power rollers 103 are in contact with the sides of the casting. The controller controls the second travel motor 14 to start. Machine 14 restarts, driving the two clamping bases 101 to move relative to each other until the side of the buffer roller 18 of the buffer mechanism 16 is in contact with the end face of the casting. The controller then starts the first traveling motor 201, which drives the traveling screw 206 to rotate. The traveling collar 205 sleeved on the traveling screw 206 moves accordingly. The grinding fixing block 202 moves within the grinding groove 4 and the traveling truss 204 in cooperation with the first sliding groove 9 and the traveling guide rail 8, until the side grinding wheel 501 is in contact with the side of the casting, and the end face grinding wheel 502... The casting is clamped by clamping mechanism 1 when it is in contact with the cut end face of the casting. The first rotating motor 104 is started by the controller, which drives the power roller 103 to rotate. The power rollers 103 on the two roller support seats 102 rotate in the same direction, and the casting placed on the two power rollers 103 also rotates. The grinding motor 203 is started by the controller, and the two grinding motors 203 drive the end face grinding wheel 502 and the side grinding wheel 501 respectively to grind the side and cut end face of the casting. After grinding is completed, the mechanism is turned off. The first rotating motor 104 and the grinding motor 203 start the first traveling motor 201, causing the two grinding fixing blocks 202 to move away. The ground casting is then transferred out by external equipment, thus completing the grinding process. To grind castings of the same length but different diameters, the position of the grinding mechanism only needs to be adjusted. To grind castings of different lengths, the distance between the two clamping bases 101 needs to be readjusted. This device is suitable for grinding castings of different lengths and diameters. It has high grinding efficiency and speed, and can reduce labor costs.
