[0024] Reference Figure 1 to Figure 4 A transport line comprises a frame 1, a slide rail 2 arranged along the front-to-back direction is provided on the frame 1, a slider 3 is provided on the slide rail 2, the slider 3 is slidably connected to the slide rail 2, a front-to-back driving device is provided on the frame 1, the front-to-back driving device is drivingly connected to the left-to-right driving device, the front-to-back driving device drives the left-to-right driving device to reciprocate along the front-to-back direction, the left-to-right driving device is drivingly connected to the latch 4, the left-to-right driving device drives the latch 4 to reciprocate left and right, an opening 5 corresponding to the latch 4 is provided on the slider 3, and the latch 4 can be inserted into the opening 5.

[0025] In this embodiment, the semi-finished engine cylinder block can be placed on the slider 3, and the left and right driving devices drive the pin 4 to be inserted into the opening 5. The left and right driving devices are driven to move forward and backward by the front and rear driving devices, thereby driving the slider 3 to move in the front and rear directions. The movement direction of the slider 3 can be guided by the setting of the slide rail 2. During use, the slider 3 can transport the semi-finished engine cylinder block to the work station for removing the sprue and the pressure relief strip. The semi-finished engine cylinder block is supported by the slider 3. The user can use the slider 3 as a processing platform for the semi-finished engine cylinder block, so that the sprue and pressure relief strip on the semi-finished engine cylinder block can be directly knocked manually or by a stacking robot. The processing is convenient and the structure of the transport chain 16 is avoided, which has a longer service life.

[0026] As a further preferred embodiment, the left and right drive device comprises a bracket 6, a left and right cylinder 7, and a push plate 8. The left and right cylinder 7 is fixedly arranged on the bracket 6. The left and right cylinder 7 is driven to connect the push plate 8. The left and right cylinder 7 drives the push plate 8 to move left and right. The push plate 8 is connected to the latch 4. The front and rear drive device is driven to connect the bracket 6. The structure is simple and convenient to set. When in use, the left and right cylinder 7 drives the push plate 8 to move left and right, and the latch 4 is driven to move in the left and right direction through the push plate 8. Optionally, the bracket 6 is fixedly connected to the front and rear drive device, and the bracket 6 is driven to move forward and backward through the front and rear device.

[0027] Further as a preferred embodiment, a through hole 9 is opened on the push plate 8 along the left-right direction, a flange 11 is provided on the inner wall of the through hole 9, the flange 11 is arranged at the end of the through hole 9 close to the slider 3, and an annular groove is provided on the outer side surface of the latch 4, and the flange 11 extends into the annular groove.

[0028] As a further preferred embodiment, a mounting opening 12 is provided on one side of the push plate 8, and the mounting opening 12 is connected to the through hole 9. The structure is simple and convenient to set up, and the latch 4 can be installed through the mounting opening 12 before use.

[0029] As a further preferred embodiment, a bushing 15 is provided on the bracket 6, the bushing 15 is fixedly connected to the bracket 6, the latch 4 passes through the bushing 15, and the bushing 15 is slidably connected to the latch 4. The structure is simple and convenient to set up. When the latch 4 needs to be inserted into the opening 5 on the slider 3, the left and right cylinders 7 drive the push plate 8 to move toward the opening 5, thereby driving the latch 4 to be inserted into the opening 5 on the slider 3.

[0030] In actual use, if the push plate 8 is directly fixed to the connected latch 4 so that the latch 4 is directly inserted into the opening 5 under the drive of the front and rear drive devices, at this time, due to the relatively large mass of the semi-finished engine cylinder block, the latch 4 is prone to bending. Once the latch 4 is bent, the latch 4 may be stuck in the opening 5 and cannot be pulled out. It is possible that the latch 4 cannot be smoothly and accurately inserted into the opening 5 again after being pulled out.

[0031] In this embodiment, the bolt 4 is installed in the through hole 9 through the installation opening 12, the bolt 4 passes through the bushing 15, and the bolt 4 is inserted into the opening 5. The bolt 4 drives the slider 3 to move in the front-to-back direction under the drive of the front-to-back drive device. The length of the bolt 4 where the outer wall of the bolt 4 cooperates with the bushing 15 is called the first section, the length of the bolt 4 where the outer wall of the bolt 4 cooperates with the opening 5 is called the second section, and the length of the bolt 4 where the annular groove cooperates with the flange 11 is called the third section. Since the bushing 15 and the opening 5 wrap the bolt 4, the positions where stress concentration may occur on the bolt 4 during the movement of the slider 3 are mainly at the end of the first section close to the second section, the two ends of the second section, and the two ends of the third section. Since there is a corner at the annular groove of the bolt 4, and the bolt 4 has no obvious shape change in the first and second sections, the stress concentration of the bolt 4 at the annular groove is the largest, so that if the bolt 4 is bent and deformed by force during the process of driving the slider 3 to slide in the front-to-back direction, the positions where the bolt 4 first deforms are at the two ends of the third section.

[0032] When the two ends of the third section of the latch 4 are deformed, the latch 4 has been inserted into the opening 5 and does not affect the fit between the latch 4 and the opening 5. When the left and right cylinders 7 drive the push plate 8 to retract, the flange 11 on the push plate 8 drives the annular groove to retract. The deformation of the two ends of the third section of the latch 4 does not affect the sliding of the latch 4. In addition, if the two ends of the third section of the latch 4 are deformed, the center of gravity of the third section of the latch 4 will change, causing the latch 4 to rotate relative to the bushing 15 and the flange 11, so that the bent part near the third section of the latch 4 is downward; in this way, the fit between the latch 4 and the bushing 15 and the fit between the latch 4 and the opening 5 is still not affected.

[0033] As a further preferred embodiment, the bracket 6 includes a flat plate 13 and a vertical plate 14, the flat plate 13 and the vertical plate 14 are perpendicular to each other and fixedly connected to each other, the front and rear drive devices are drivingly connected to the flat plate 13, the left and right cylinders 7 are fixedly connected to the flat plate 13, a fixing hole is provided on the vertical plate 14, and the bushing 15 is fixedly connected to the fixing hole. The structure is simple and convenient to set up, the bushing 15 is fixedly connected to the fixing hole, and the bushing 15 is set in the fixing hole, so that the bushing 15 can be conveniently fixed.

[0034] As a further preferred embodiment, the front and rear drive device comprises a transport chain 16, a sprocket 17, a conveying block 18, and a motor 19. At least two sprockets 17 are provided, and all the sprockets 17 are provided on the left or right side of the frame 1. All the sprockets 17 are connected to the frame 1 through a rotating shaft, and all the sprockets 17 are connected to the transport chain 16 in a transmission manner. The motor 19 is connected to one sprocket 17 in a driving manner. The transport chain 16 drives the conveying block 18 to reciprocate along the front and rear directions, and the left and right drive devices are provided on the conveying block 18. The structure is simple and convenient to set up. When in use, the motor 19 drives the sprocket 17 to rotate, thereby driving the transport chain 16 to move, and the transport chain 16 drives the conveying block to move. The left and right drive devices are provided on the conveying block. In some embodiments, the flat plate 13 is provided on the conveying block. Through the setting of this structure, the split setting of the front and rear drive devices and the slider 3 is realized, so as to prevent the semi-finished product of the engine cylinder block on the slider 3 from dropping a large amount of debris into the front and rear drive devices.

[0035] Preferably, the motor 19 is a servo motor.

[0036] As a further preferred embodiment, a dust cover 20 is provided on the frame 1, and the dust cover 20 covers the transport chain 16, the transport block and the left and right drive devices. The dust cover 20 is provided with an escape opening on the side close to the slider 3, and the latch 4 extends from the escape opening. The structure is simple and convenient to set up. Through the setting of the dust cover 20 of this structure, aluminum debris dropped from the semi-finished product of the engine cylinder block can be effectively prevented from entering the transport chain 16.

[0037] As a further preferred embodiment, two support rails 32 are provided on the slider 3, and a guide rod 22 is provided between the two support rails 32. The lengths of the support rails 32 and the guide rod 22 are respectively arranged along the front-rear direction, and a front stopper assembly 29 is provided at the front side of the guide rod 22, and a rear stopper assembly 24 is provided at the rear side of the guide rod 22. The structure is simple and convenient to set up. The guide rod 22 is used to guide the moving direction of the semi-finished engine cylinder block, and at the same time, the sliding direction of the semi-finished engine cylinder block is limited. By setting the front stopper assembly 29 and the rear stopper assembly 24, the semi-finished engine cylinder block can be limited, and the semi-finished engine cylinder block can be limited on the guide rod 22, so as to avoid the semi-finished engine cylinder block from falling during the sliding process.

[0038] In some embodiments, the front limiting assembly 29 includes a limiting rod 10, which is arranged on the slider 3, and the upper end of the limiting rod 10 is higher than the supporting rail 32. The structure is simple and convenient to set up. Through the setting of the structure, the engine cylinder block can be limited from the front side.

[0039] In some embodiments, the front limit assembly 29 further includes a sleeve 30 and a spring 31. The sleeve 30 is fixedly connected to the slider 3, and the limit rod 10 is slidably connected to the sleeve 30. The limit rod 10 is arranged vertically, and one end of the spring 31 is connected to the sleeve 30 or the slider 3, and the other end of the spring 31 is connected to the limit rod 10. The structure is simple and convenient to set. Through the setting of the spring 31, the limit rod 10 can be easily reset. In actual use, when the limit rod 10 moves downward, the engine cylinder can be released from the limit. When the limit rod 10 moves downward under the action of an external force, the spring 31 will be deformed. When the external force disappears, the limit rod 10 can be reset under the action of the force of the spring 31. In actual use, the spring 31 is arranged above the slider 3, the lower end of the spring 31 is connected to the sleeve 30, and the upper end of the spring 31 is connected to the limit rod 10. When the limit rod 10 moves downward, the spring 31 is compressed.

[0040] In some embodiments, the rear limit assembly 24 includes a support frame 25, a first shaft 26, a limit block 27, and a stop block 28. The support frame 25 is arranged at the rear side of the guide rod 22, the support frame 25 is fixedly connected to the slider 3, the support frame 25 is rotatably connected to the limit block 27 through the first shaft 26, the center of gravity of the limit block 27 is arranged below the first shaft 26, the stop block 28 is arranged on the support frame 25, the stop block 28 is arranged at the front side of the limit block 27, and the rotation track of the limit block 27 intersects with the stop block 28. The structure is simple and convenient to set. Through the setting of the structure, the unidirectional rotation of the limit block 27 is realized, for example, the stop block 28 blocks the limit block 27, effectively avoiding the reverse rotation of the limit block 27, so that the engine cylinder body cannot return along the road after passing the limit block 27, thereby limiting the engine cylinder body from the rear side.

[0041] In some embodiments, the top rear side of the stop block 27 is provided with a chamfer or a rounded corner. This structure is simple and convenient to set up. With this structure, when the engine cylinder body passes through the stop block 27, the engine cylinder body can pass through the chamfer or rounded corner more smoothly. In this embodiment, a rounded corner is used.

[0042] As a further preferred embodiment, a pulley 23 is provided on the slider 3, and the pulley 23 slidably cooperates with the slide rail 2. The structure is simple and convenient to set up. Through the setting of the structure, the relative movement between the slider 3 and the slide rail 2 is smoother.

[0043] The preferred embodiments of the present invention are specifically described above, but the invention is not limited to the embodiments.
