[0002] The engine cylinder block directional blanking device is an automated equipment specially used for engine cylinder block blanking. It is used to achieve directional, accurate and efficient blanking of engine cylinder blocks, thereby improving the automation level and production efficiency of the production line.

[0003] In the prior art, when the engine cylinder body needs to be unloaded, the engine cylinder body is first placed on a roller conveyor, and the roller conveyor is driven to move the engine cylinder body thereon until the engine cylinder body moves to the grasping area.

[0018] A directional blanking process for an engine cylinder block, comprising the following steps:

Preparation: Check the operating status of the equipment to ensure that it is working properly, then place the cylinder body on the roller conveyor, start the drive motor to drive the bidirectional screw to rotate, so that the two limit plates move toward the middle of the bidirectional screw under the first limit of the guide groove, so that the clamping plates on the two limit plates clamp the two ends of the cylinder body;

[0020] Step 2: Cylinder transmission: Drive the roller conveyor to move the cylinder. The movement of the cylinder drives the clamping plate to slide in the moving groove and elastically compress the compression spring 2, so that the cylinder only moves in a straight line.

[0021] Step 3: Cylinder grabbing and orienting: When the cylinder moves to the grabbing area, the roller conveyor stops running. During this process, the concave block is inserted into the clamping groove through the two telescopic blocks and the fixed block, and the clamping plate is kept stationary. Then the manipulator is driven to grab the cylinder. After grabbing the cylinder, the drive motor is driven to rotate in the opposite direction until the limit plate is reset. At this time, contact 1 and contact 2 are in conflict, so that the clamping plate is no longer stationary. The clamping plate is reset by the elastic release of compression spring 2. At the same time, the manipulator is driven to rotate and flip the cylinder.

[0022] Step 4: Cylinder movement, release, and equipment reset: At this time, the robot is driven to move the oriented cylinder into the material cage and release the cylinder, and then the robot is reset to prepare for the next work.

[0023] The beneficial effects of the present invention are as follows:

[0024] 1. The present invention starts the driving motor to drive the bidirectional screw to rotate, so that the two limit plates move toward the middle of the bidirectional screw under the first limit of the guide groove, thereby limiting the moving trajectory of the cylinder body on the roller conveyor, avoiding the problem of deviation of the existing cylinder body when moving on the roller conveyor, so that the manipulator does not need to adjust the grasping angle, saving the time spent on adjusting the grasping angle, and thus improving the efficiency of cylinder unloading.

[0025] 2. The present invention reduces the friction resistance of the clamping plate when it slides by the rolling of the balls, making the sliding of the clamping plate smoother, further maintaining the moving speed of the cylinder on the roller conveyor, and inserting the concave block into the clamping groove so that the clamping plate remains in the plugged state after the cylinder is grasped by the robot, preventing the problem of scratches on the cylinder surface caused by friction between the clamping plate and the cylinder surface due to the resetting of the clamping plate, and resetting the clamping plate through the contact between contact one and contact two, preparing for the next clamping of the cylinder.

[0039] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0040] Example 1

[0041] like Figures 1 to 9As shown, an engine cylinder block directional unloading device according to an embodiment of the present invention comprises a roller conveyor 1, and a manipulator 2 is provided on one side of the roller conveyor 1;

[0042] A clamping assembly is provided at one end of the roller conveyor 1. The clamping assembly includes a fixed plate 31. A limit plate 36 is symmetrically slidably provided on the fixed plate 31. The engine cylinder on the roller conveyor 1 is limited by the two limit plates 36 moving toward each other.

[0043] The clamping assembly also includes a support plate 32, which is fixed to one end of the fixed plate 31. A drive motor 33 is fixedly connected to the support plate 32. A guide groove 34 is opened on one side of the fixed plate 31. A bidirectional screw rod 35 is rotatably connected in the guide groove 34. Two limit plates 36 both slide in the guide groove 34.

[0044] Specifically, the two limit plates (36) are respectively connected to the two ends of the bidirectional screw rod (35) by threads, and the bottom ends of the two limit plates (36) are both located above the roller conveyor (1);

[0045] The above solution still has some shortcomings in actual use. During the process of the roller conveyor 1 conveying the engine cylinder body, since the engine cylinder body contacts the top of the roller on the roller conveyor 1, and there is a distance between adjacent rollers on the roller conveyor 1, the roller conveyor 1 inevitably vibrates during operation, causing the engine cylinder body thereon to vibrate during movement, thereby causing the engine cylinder body to shift, resulting in the robot 2 needing to adjust the gripping angle according to the position of the engine cylinder body after shifting, which reduces the efficiency of material unloading.

[0046] Therefore, the present invention solves this problem by setting up a corresponding structure. When the cylinder body needs to be directional unloading, the cylinder body is first placed on the roller conveyor 1, and the bidirectional screw 35 is driven to rotate by starting the drive motor 33, so that the two limit plates 36 move toward the middle of the bidirectional screw 35 under the limit of the guide groove 1 34, which is used to limit the movement trajectory of the cylinder body on the roller conveyor 1, and then the roller conveyor 1 is driven to move the cylinder body. When the cylinder body moves to the grabbing area, the roller conveyor 1 stops running, and the manipulator 2 is driven to rotate and flip the cylinder body, and then the directional cylinder body is moved into the material cage and released, thereby completing the directional unloading operation of the cylinder body, and then the manipulator 2 is reset to prepare for the next work.

[0047] The present invention starts the driving motor 33 to drive the bidirectional screw 35 to rotate, so that the two limit plates 36 move toward the middle of the bidirectional screw 35 under the limit of the guide groove 1 34, thereby limiting the movement trajectory of the cylinder body on the roller conveyor 1, avoiding the problem of the existing cylinder body offset when moving on the roller conveyor 1, and eliminating the need for the manipulator 2 to adjust the gripping angle, saving the time spent on adjusting the gripping angle, thereby improving the efficiency of cylinder unloading.

[0048] like Figures 2 to 9 As shown, in this embodiment, an anti-scratch component is provided on one side of the two limit plates 36, and the anti-scratch component includes a movable groove 41. The movable groove 41 is provided on one side of the limit plate 36, and a clamping plate 43 is slidingly provided in the movable groove 41. In the process of the two limit plates 36 clamping the engine cylinder body, the two clamping plates 43 will clamp the engine cylinder body, and the engine cylinder body is moved by driving the roller conveyor 1 to drive the clamping plate 43 to slide in the movable groove 41, so that the clamping plate 43 and the engine cylinder body maintain relative movement.

[0049] Specifically, when the cylinder body moves, the two clamping plates 43 clamp the cylinder body and move synchronously with the movement of the cylinder body, so that the clamping plates 43 slide in the moving groove 41, so that the clamping plates 43 and the engine cylinder body remain relatively fixed while the cylinder body and the clamping plates 43 also move, avoiding the problem of friction between the cylinder body and the clamping plates 43 due to the movement of the cylinder body while the clamping plates 43 do not move, causing damage to the cylinder body surface.

[0050] like Figures 4 to 7 As shown, the anti-scratch assembly of this embodiment further includes multiple sets of arc grooves 1 42, which are all formed on the inner wall of the movable groove 41. One side of the clamping plate 43 is formed with multiple sets of arc grooves 2 44, and multiple balls 45 are rolled in each set of arc grooves 2 44.

[0051] Each set of arc grooves 2 44 corresponds to each set of arc grooves 1 42 on a one-to-one basis. The plurality of balls 45 in each set of arc grooves 2 44 are all rolled in the corresponding arc groove 1 42 .

[0052] Specifically, when the clamping plate 43 moves, the rolling action of the balls 45 reduces the frictional resistance of the clamping plate 43 when sliding, making the clamping plate 43 slide more smoothly, further maintaining the moving speed of the cylinder on the roller conveyor 1.

[0053] like Figures 7 to 9 As shown, in this embodiment, one end of the clamping plate 43 is fixedly connected to a concave block 46, and contraction grooves 47 are symmetrically opened in the concave block 46. A telescopic block 48 is slidably connected in each contraction groove 47, and a compression spring 49 is fixedly connected between one end of the telescopic block 48 and the inner wall of the contraction groove 47 in which it is located;

[0054] A second guide groove 410 is defined in the concave block 46 , and a third guide groove 411 is defined in the concave block 46 . The second guide groove 410 is connected to a contraction groove 47 below it, and the third guide groove 411 is connected to another contraction groove 47 below it.

[0055] A transmission groove 412 is defined within the concave block 46 , to which an electric telescopic rod 413 is fixedly connected. A guide rack 414 is symmetrically and slidably connected within the transmission groove 412 , and a transmission gear 415 is rotatably connected within the guide rack 414 . The transmission groove 412 is connected to the second guide groove 410 and the third guide groove 411 , and both guide racks 414 are meshed with the transmission gear 415 .

[0056] One end of a guide rack 414 is located on the motion trajectory of the electric telescopic rod 413, and the other end is fixedly connected to a connecting plate 1 417, the other end of which is fixed to the surface of a telescopic block 48. Another guide rack 414 has a return spring 416 fixedly connected between one end and the inner wall of the transmission groove 412, and the other end is fixedly connected to a connecting plate 2 418, the other end of which is fixed to the surface of another telescopic block 48.

[0057] A compression spring 2 419 is symmetrically fixedly connected between one end of the clamping plate 43 and one end of the movable slot 41. A snap-fit slot 420 is provided at one end of the movable slot 41. A fixed block 421 is fixedly connected to the inner wall of the snap-fit slot 420. The shape of the fixed block 421 matches the shape of the telescopic block 48. The fixed block 421 is on the motion trajectory of the concave block 46. Contact 1 422 is fixedly connected to one side of each of the two limiting plates 36. Contact 2 423 is fixedly connected to both ends of the guide slot 1 34. Contact 2 423 is on the motion trajectory of contact 1 422 on its adjacent limiting plate 36.

[0058] Specifically, the contraction groove 47 is composed of two rectangular grooves and a cylindrical groove. The cylindrical groove is located between the two rectangular grooves, and both ends of the cylindrical groove are connected to the two rectangular grooves. The telescopic block 48 is composed of a trapezoidal block, a cylindrical block and a rectangular plate. The bottom of the trapezoidal block is fixed to one end of the cylindrical block, the other end of the cylindrical block is fixed to one side of the rectangular plate, and the other side of the rectangular plate is fixed to one end of a compression spring 49.

[0059] The rectangular plate slides in a rectangular groove, the cylindrical block slides in the cylindrical groove, the rectangular plate slides in another rectangular groove, and the other end of the compression spring 49 is fixed to the inner wall of the other rectangular groove;

[0060] The transmission slot 412 consists of two long slots and a cylindrical slot. The cylindrical slot is located between the two long slots and is connected to them. The electric telescopic rod 413 is fixed in one long slot, and this long slot is connected to the second guide slot 410. The return spring 416 is fixed in the other long slot, and this long slot is connected to the third guide slot 411. The guide rack 414 fixed to the first connecting plate 417 slides in the long slot where the electric telescopic rod 413 is located. The guide rack 414 fixed to the second connecting plate 418 slides in the other long slot. The transmission gear 415 rotates in the cylindrical slot.

[0061] The fixing block 421 is composed of a cone and a guide post. The bottom end of the cone is fixed to one end of the guide post, and the other end of the guide post is fixed to one end of the clamping groove 420.

[0062] When the two clamping plates 43 clamp the cylinder body, the clamping groove 420 and the fixing block 421 are not in contact, the contraction groove 47 and the second compression spring 419 are not deformed, and the electric telescopic rod 413 is in a contracted state;

[0063] When the cylinder moves, the clamping plate 43 drives the concave block 46 to move toward the clamping groove 420. During this process, the compression spring 2 419 is elastically compressed until the concave block 46 is inserted into the clamping groove 420. At this time, the cylinder moves to the gripping area.

[0064] During the insertion of the concave block 46 into the engaging groove 420, the telescopic block 48 first conflicts with the fixed block 421, causing the rectangular plate to conflict with the cone. As the concave block 46 is continuously inserted into the engaging groove 420, the telescopic block 48 contracts into the contraction groove 47 and elastically compresses the compression spring 1 49. Under the action of the connecting plate 1 417 and the connecting plate 2 418, the two guide racks 414 are driven to move and the return spring 416 is elastically stretched until the cone no longer conflicts with the rectangular plate, so that the fixed block 421 and the two telescopic blocks 48 are in a card-engaged state. At this time, under the action of the return spring 416 and the compression spring 1 49 being elastically released, the two guide racks 414 and the telescopic block 48 are reset.

[0065] During the return process of the limit plate 36, the two clamping plates 43 no longer clamp the cylinder body. At this time, the second compression spring 419 is in an elastically released state. Since the fixed block 421 and the two telescopic blocks 48 are in a clamping state, the concave block 46 continues to be inserted into the clamping groove 420.

[0066] Until the limit plate 36 is reset, the contact 1 422 contacts the contact 2 423, thereby extending the electric telescopic rod 413, pushing one guide rack 414 to move, and driving the other guide rack 414 to move toward each other through the transmission of the transmission gear 415, so that the telescopic block 48 contracts and elastically compresses the contraction groove 47 and the elastic tension reset spring 416. At this time, the two telescopic blocks 48 are no longer engaged with the fixed block 421. Under the action of the elastic release of the compression spring 2 419, the clamping plate 43 is reset to prepare for the next clamping.

[0067] The present invention reduces the friction resistance of the clamping plate 43 when it slides by the rolling of the ball 45, making the sliding of the clamping plate 43 smoother, further maintaining the moving speed of the cylinder on the roller conveyor 1, and inserting the concave block 46 into the clamping groove 420, so that the clamping plate 43 remains in the plugged state after the cylinder is grasped by the manipulator 2, preventing the problem of scratches on the cylinder surface caused by friction between the clamping plate 43 and the cylinder surface due to the resetting of the clamping plate 43, and resetting the clamping plate 43 through the contact between the contact 1 422 and the contact 2 423, preparing for the next clamping of the cylinder.

[0068] Example 2

[0069] like Figures 1 to 9 As shown, compared with Example 1, another embodiment of the present invention is: a directional blanking process for an engine cylinder block, the specific steps include:

[0070] Step 1, preparation: Check the operating status of the equipment to ensure that it is working properly, then place the cylinder body on the roller conveyor 1, start the drive motor 33 to drive the bidirectional screw 35 to rotate, so that the two limit plates 36 move toward the middle of the bidirectional screw 35 under the limit of the guide groove 1 34, so that the clamping plates 43 on the two limit plates 36 clamp the two ends of the cylinder body;

[0071] Step 2: Cylinder transmission: Drive the roller conveyor 1 to move the cylinder. The movement of the cylinder drives the clamping plate 43 to slide in the moving groove 41 and elastically compress the second compression spring 419, so that the cylinder only moves in a straight line.

[0072] Step 3: Cylinder grabbing and orienting: When the cylinder moves to the grabbing area, the roller conveyor 1 stops running. During this process, the concave block 46 is inserted into the clamping groove 420 through the two telescopic blocks 48 and the fixed block 421, and the clamping plate 43 is kept stationary. Then the manipulator 2 is driven to grab the cylinder. After grabbing the cylinder, the drive motor 33 is driven to rotate in the opposite direction until the limit plate 36 is reset. At this time, the contact 1 422 and the contact 2 423 are in conflict, so that the clamping plate 43 is no longer kept stationary. The clamping plate 43 is reset under the action of the elastic release of the compression spring 2 419. At the same time, the manipulator 2 is driven to rotate and flip the cylinder.

[0073] Step 4: Cylinder movement, release, and equipment reset: At this time, drive the manipulator 2 to move the oriented cylinder into the material cage and release the cylinder, then reset the manipulator 2 to prepare for the next work.

[0074] Working principle:

[0075] When the cylinder body needs to be directional unloading, the cylinder body is first placed on the roller conveyor 1, and the driving motor 33 is started to drive the bidirectional screw 35 to rotate, so that the two limit plates 36 move toward the middle of the bidirectional screw 35 under the limit of the guide groove 1 34, so that the two clamping plates 43 clamp the cylinder body, and then the driving motor 33 is turned off, and then the roller conveyor 1 is driven to operate to move the cylinder body;

[0076] At this time, the two clamping plates 43 move synchronously with the movement of the cylinder body toward the clamping groove 420. Under the rolling action of the ball 45, the friction resistance of the clamping plates 43 when sliding is reduced, so that the clamping plates 43 slide more smoothly in the moving groove 41. In this process, the compression spring 2 419 is elastically compressed until the concave block 46 is inserted into the clamping groove 420. At this time, the cylinder body moves to the grasping area.

[0077] During the insertion of the concave block 46 into the engaging groove 420, the telescopic block 48 first conflicts with the fixed block 421, causing the rectangular plate to conflict with the cone. As the concave block 46 is continuously inserted into the engaging groove 420, the telescopic block 48 contracts into the contraction groove 47 and elastically compresses the compression spring 1 49. Under the action of the connecting plate 1 417 and the connecting plate 2 418, the two guide racks 414 are driven to move and the return spring 416 is elastically stretched until the cone no longer conflicts with the rectangular plate, so that the fixed block 421 and the two telescopic blocks 48 are in a card-engaged state. At this time, under the action of the return spring 416 and the compression spring 1 49 being elastically released, the two guide racks 414 and the telescopic block 48 are reset.

[0078] When the cylinder moves to the grabbing area, the roller conveyor 1 stops running, and then drives the manipulator 2 to grab the cylinder. After grabbing the cylinder, the drive motor 33 is driven to rotate in the reverse direction to reset the limit plate 36.

[0079] During the return process of the limit plate 36, the two clamping plates 43 no longer clamp the cylinder body. At this time, the second compression spring 419 is in an elastically released state. Since the fixed block 421 and the two telescopic blocks 48 are in a clamping state, the concave block 46 continues to be inserted into the clamping groove 420.

[0080] Until the limit plate 36 is reset, the first contact 422 contacts the second contact 423, thereby extending the electric telescopic rod 413, pushing one guide rack 414 to move, and the transmission gear 415 drives the other guide rack 414 to move toward each other, causing the telescopic block 48 to contract and elastically compress the contraction groove 47 and the elastic tension return spring 416. At this time, the two telescopic blocks 48 are no longer engaged with the fixed block 421. Under the action of the elastic release of the second compression spring 419, the clamping plate 43 is reset, preparing for the next clamping.

[0081] Then drive the robot 2 to rotate and flip the cylinder body, then move the oriented cylinder body into the material cage and release the cylinder body, thereby completing the directional unloading operation of the cylinder body, and then reset the robot 2 to prepare for the next work.

[0082] The basic principles, main features, and advantages of the present invention are shown and described above.
