[0002] Machine tool castings can also be called large castings, bed bodies, bases, workbenches, etc. When castings are manufactured, they are metal formed objects obtained by various casting methods. By injecting liquid metal into a pre-prepared mold through various different methods and then grinding and other processes after cooling, grooving processing is required during the manufacturing of machine tool castings. During grooving processing, workers need corresponding clamping devices to fix the castings to facilitate the workers to perform grooving.

[0003] When workers perform grooving processing on castings, they need to perform grooving operations on the castings from different directions. However, after the traditional clamping device fixes the castings, it cannot adjust the direction of the castings. Therefore, workers still need to frequently remove the castings from the clamping device, adjust the direction and then fix them again, which greatly reduces the efficiency of grooving processing of castings. To improve the grooving efficiency of castings, we propose a grooving clamping device for machine tool castings. Content of the Utility Model

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0026] Please refer to Figure 1-6, the present utility model provides a technical solution: a grooving clamping device for a machine tool casting. A grooving clamping device for a machine tool casting includes a base 1, and a plurality of feet 4 are fixedly installed below the base 1. A rotating mechanism 2 is arranged on the base 1, and a clamping mechanism 3 is fixedly installed on the rotating mechanism 2. A plurality of mounting holes and a plurality of mating grooves are formed in the base 1; the rotating mechanism 2 includes a rotating ring 7, the rotating ring 7 is rotatably installed on the base 1, a rotating frame 6 is fixedly installed on the rotating ring 7, a first stopper 8 is fixedly installed on the front outer surface of the rotating ring 7, a second stopper 9 is fixedly installed on the rear outer surface of the rotating ring 7, a plurality of inclined convex blocks 10 are fixedly installed on the left outer surface of the rotating ring 7, a plurality of nuts 31 are threadedly connected to the rotating ring 7, a plurality of threaded holes are formed in the rotating ring 7, and an automatic safety component 11 is fixedly installed on the base 1.

[0027] During use, the staff first place the casting on the clamping mechanism 3 and clamp the casting. Then, the direction of the clamping mechanism 3 is adjusted through the rotating mechanism 2 to adjust the angle of the casting, and then the grooving operation is performed on the casting.

[0028] The automatic safety component 11 includes a baffle 12, the baffle 12 is fixedly installed on the base 1, a fixed rod 15 is fixedly installed on the baffle 12, an auxiliary hollow block 13 is fixedly installed on the base 1, a telescopic arm 14 is slidably installed in the auxiliary hollow block 13, the telescopic arm 14 is slidably connected to the fixed rod 15, a spring is sleeved on the fixed rod 15, and the spring is fixedly connected to the baffle 12 and the telescopic arm 14 respectively. An insurance hollow block 16 is slidably installed on the auxiliary hollow block 13, a block 17 is fixedly installed in the insurance hollow block 16, a mating notch 18 is formed in the telescopic arm 14, the top end of the telescopic arm 14 is fixedly connected to an inclined block 19, a plurality of notches are formed in the auxiliary hollow block 13, and a long hole is formed in the telescopic arm 14.

[0029] During use, the operator rotates the rotating frame 6 counterclockwise. Then, the inclined surface bump 10 fixedly installed on the rotating frame 6 also starts to rotate with the rotating frame 6. When the inclined surface bump 10 rotates, it will push the inclined block 19 forward. After that, the telescopic arm 14 also moves forward with the cooperation of the auxiliary hollow block 13. Then, the telescopic arm 14 compresses the spring. When the inclined surface bump 10 is not in contact with the inclined block 19, the spring will push the inclined block 19 and the telescopic arm 14 forward, thus jamming the inclined surface bump 10 and preventing the rotating frame 6 from rotating counterclockwise. After adjusting the angle, tighten the nut 31 to fix the rotating mechanism 2. Then, start grooving the casting. When the rotating frame 6 rotates 180 degrees clockwise, with the cooperation of the auxiliary hollow block 13, the second stop block 9 moves the insurance hollow block 16 to the right, thus clamping the block 17 into the mating notch 18, making the inclined block 19 retract into the auxiliary hollow block 13. Then, the rotating frame 6 can rotate 180 degrees counterclockwise to reset. When the moving frame rotates 180 degrees counterclockwise, the first stop block 8 moves the insurance hollow block 16 to the left, and the block 17 comes out of the mating notch 18. Under the action of the spring, the inclined block 19 resets.

[0030] The clamping mechanism 3 includes a frame 21 fixedly installed on the rotating frame 6. A number of protective covers 25 are fixedly installed on the frame 21. A T-shaped long arm 22 is fixedly installed inside the frame 21. A first clamping plate 23 and a second clamping plate 24 are slidably sleeved on the T-shaped long arm 22. Both the first clamping plate 23 and the second clamping plate 24 are slidably connected to the protective covers 25. A first double-threaded rod 28 and a second double-threaded rod 29 are rotatably installed on the frame 21. The first double-threaded rod 28 is threadedly connected to both the first clamping plate 23 and the second clamping plate 24. The second double-threaded rod 29 is threadedly connected to both the first clamping plate 23 and the second clamping plate 24. T-shaped notches and a number of threaded holes are provided on both the first clamping plate 23 and the second clamping plate 24; The clamping mechanism 3 further includes a clamping motor 20 fixedly installed on the rotating frame 6. The output shaft of the clamping motor 20 is fixedly sleeved with a driving gear 26. Chain wheels 30 are fixedly sleeved on both sides of the first double-threaded rod 28 and the second double-threaded rod 29. Chains are tensionedly sleeved between the left chain wheels 30 and between the right chain wheels 30. The right end of the first double-threaded rod 28 is fixedly connected to a driven gear 27, and the driven gear 27 meshes with the driving gear 26. A number of mounting holes and a number of mating grooves are provided on the frame 21.

[0031] During operation, the staff places the casting on the T-shaped long arm 22, then turns on the clamping motor 20. The output shaft of the clamping motor 20 drives the driving gear 26 to rotate, and the driving gear 26 then drives the driven gear 27 meshing with it to rotate. Under the action of the sprocket 30 and the chain, the first double-threaded rod 28 and the second double-threaded rod 29 start to rotate in the same direction. Then, under the restriction of the T-shaped long arm 22, the first clamping plate 23 starts to move to the right, and the second clamping plate 24 starts to move to the left until the casting is clamped. Then, the clamping motor 20 is turned off. During the grooving process, debris will be generated, and the protective cover 25 can prevent the first double-threaded rod 28 and the second double-threaded rod 29 from being contaminated by the debris, causing damage to the device.

[0032] A debris collection bin 5 is fixedly installed below the frame 21, which can collect the debris to prevent the debris from entering the device and causing damage to the device.

[0033] A number of convex strips are fixedly connected to the outer surface on the right side of the first clamping plate 23 and the outer surface on the left side of the second clamping plate 24, which can clamp the casting more tightly.

[0034] A number of heat sinks are fixedly connected to the outer surface of the clamping motor 20, which can improve the heat dissipation performance of the clamping motor 20.

[0035] Working principle: When in use, the staff places the casting on the T-shaped long arm 22, then turns on the clamping motor 20. The output shaft of the clamping motor 20 drives the driving gear 26 to rotate, and the driving gear 26 then drives the driven gear 27 meshing with it to rotate. Under the action of the sprocket 30 and the chain, the first double-threaded rod 28 and the second double-threaded rod 29 start to rotate in the same direction. Then, under the restriction of the T-shaped long arm 22, the first clamping plate 23 starts to move to the right, and the second clamping plate 24 starts to move to the left until the casting is clamped. Then, the clamping motor 20 is turned off. During the grooving process, debris will be generated, and the protective cover 25 can prevent the first double-threaded rod 28 and the second double-threaded rod 29 from being contaminated by the debris, causing damage to the device.

[0036] Next, the staff rotates the rotating frame 6 counterclockwise, and the inclined surface convex block 10 fixedly installed on the rotating frame 6 also starts to rotate with the rotating frame 6. When the inclined surface convex block 10 rotates, it will push the inclined block 19 forward. Then, the telescopic arm 14 also moves forward under the cooperation of the auxiliary hollow block 13. Then, the telescopic arm 14 compresses the spring. When the inclined surface convex block 10 is not in contact with the inclined block 19, the spring will push the inclined block 19 and the telescopic arm 14 forward, thus clamping the inclined surface convex block 10 and preventing the rotating frame 6 from rotating counterclockwise. After adjusting the angle, turn the nut 31 tightly to fix the rotating mechanism 2. Then, start grooving the casting.

[0037] When the rotating frame 6 rotates clockwise by 180 degrees, with the cooperation of the second stopper 9 and the auxiliary hollow block 13, the safety hollow block 16 is moved to the right, so that the locking block 17 is locked into the mating notch 18, and the inclined block 19 retracts into the auxiliary hollow block 13. Then the rotating frame 6 can rotate counterclockwise by 180 degrees to reset. When the moving frame rotates counterclockwise by 180 degrees, the first stopper 8 moves the safety hollow block 16 to the left, and the locking block 17 comes out of the mating notch 18. Under the action of the spring, the inclined block 19 resets.
