Description

[0001] The utility model relates to the technical field of engine cylinder production, and more specifically to a V-shaped cylinder rotating tool. Background Art

[0002] The engine block has a V-shaped cylinder block. During the production and processing, since the processing machine tool cannot be turned over, the V-shaped cylinder block needs to be rotated 60° around the crankshaft hole direction so that one of the cylinder top surfaces is perpendicular to the spindle direction of the horizontal machining center, and then it is hoisted into the machine tool for processing.

[0003] At present, manual rotation is mostly adopted, and two cranes are used to complete the above operation. Specifically, one crane uses a hoist to lift the cylinder body vertically, so that the cylinder body is tilted and placed on the ground, and the other crane pulls the tilted cylinder body obliquely to rotate the cylinder body to a 60° posture, and then hoist it into the machine tool for processing. During the above operation, two cranes need to be manually operated to cooperate, which is difficult to operate and has low rotation efficiency. In addition, once improper operation occurs, it is very easy to cause safety accidents with casualties, and the rotation safety is low.

[0004] In summary, how to solve the low rotation efficiency and safety of the V-type cylinder is an urgent problem to be solved by those skilled in the art. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0030] The core of the utility model is to provide a V-shaped cylinder body rotating tool, which can improve the efficiency and safety of the V-shaped cylinder body rotation.

[0031] It should be noted that, in the present embodiment, the directions or positional relationships indicated by “up”, “down”, “left”, “right”, etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present application.

[0032] Please refer to Figure 1 and Figure 2 The present application provides a V-shaped cylinder rotating tool, including a cylinder placing platform 1 and a base 4. The cylinder placing platform 1 is provided with a clamping block driving mechanism 2 and a clamping block 3 for clamping and matching with the bottom of the cylinder 8. The driving end of the clamping block driving mechanism 2 is connected to the clamping block 3, and is used to drive the clamping block 3 to move so as to clamp or loosen the cylinder 8; the base 4 is located below the cylinder placing platform 1, and a gear driving mechanism 5 and a gear 6 are provided on the base 4 and at the two end positions corresponding to the cylinder placing platform 1. The driving end of the gear driving mechanism 5 is connected to the gear 6, and is used to drive the gear 6 to rotate, and the two ends of the cylinder placing platform 1 are both connected to the corresponding gear 6 through a chain 7, and are used to drive the cylinder placing platform 1 to rotate.

[0033] Specifically, a pillar is provided between the cylinder placing platform 1 and the base 4, and the bottom end of the pillar is fixed on the base 4. The cylinder placing platform 1 can be rotatably set at the top of the pillar to ensure a firm connection between the cylinder placing platform 1 and the base 4. The cylinder placing platform 1 is used to place the cylinder 8. To ensure that the cylinder 8 does not overturn during the rotation of the cylinder placing platform 1, a clamping block driving mechanism 2 and a clamping block 3 are set on the cylinder placing platform 1. The number of clamping blocks 3 is not unique. Preferably, the clamping blocks 3 can be set to be multiple, and the multiple clamping blocks 3 are evenly distributed around the placement position of the cylinder 8, and each clamping block 3 is connected to the driving end of the clamping block driving mechanism 2. When the cylinder 8 is placed in the set placement position, the clamping block driving mechanism 2 drives the clamping block 3 toward or away from the bottom of the cylinder 8 to clamp or loosen the bottom of the cylinder 8, that is, to realize the loading and unloading of the cylinder 8. In addition, the type of the clamping block driving mechanism 2 is not unique. A motor, an oil cylinder or an air cylinder can be selected as long as it can drive the clamping block 3 to move.

[0034] In addition, a rotating device for driving the cylinder placement platform 1 above it to rotate is provided on the base 4, and a gear driving mechanism 5 and a gear 6 are provided on the base 4 located below the left and right ends of the cylinder placement platform 1. The specific structure of the gear driving mechanism 5 is not unique, and it can be selected to be composed of a driving motor and a driving rod 52 connected to its output shaft. The driving rod 52 is provided with a gear 6 for driving the gear 6 to rotate. The left and right ends of the cylinder placement platform 1 are connected to the corresponding gear 6 below it through a chain 7, so as to drive the cylinder placement platform 1 to rotate through the meshing transmission of the gear 6 and the chain 7.

[0035] When the above-mentioned V-type cylinder rotating tool is operated and used, the cylinder 8 is placed on the cylinder placement platform 1 manually using the cylinder 8 hoist. After confirming the placement position, the start button of the clamping block driving mechanism 2 is pressed manually. The clamping block driving mechanism 2 drives the clamping block 3 to move to the bottom of the cylinder 8 and clamps it to fix the cylinder 8. Then the start buttons of the two gear driving mechanisms 5 are pressed. The two gear driving mechanisms 5 respectively drive the gears 6 under the two ends of the cylinder placement platform 1 to keep rotating in the same direction, so as to drive the two chains 7 located at the two ends of the driving cylinder placement platform 1 to rotate in the same direction, thereby driving the cylinder placement platform 1 to rotate to the required posture, that is, a specific processing angle. Finally, the cylinder 8 hoist is used manually to lift the cylinder 8 to the machine tool, so as to realize the processing of the cylinder 8 at a specific angle.

[0036] In summary, the manual operation only needs to use a sling to hoist the cylinder body 8 onto the cylinder body placement platform 1, start the clamping and rotation drive mechanisms one by one, and the cylinder body placement platform 1 can automatically rotate the cylinder body 8 to the desired posture, and then the manual operation uses a sling to hoist the cylinder body 8 out to the machine tool. Therefore, the present application can automatically rotate the V-shaped cylinder body 8 to the desired posture, reduce the manual labor intensity, save time and effort, improve the rotation efficiency, and reduce the risk of manual rotation.

[0037] Considering the specific structure of the cylinder body placement platform 1, based on the above embodiment, please refer to Figure 1 The cylinder body placement platform 1 is an L-shaped structure. A fixing seat 11 is provided at the bottom end of the L-shaped cylinder body placement platform 1 for cooperating with the clamping block 3 to fix the bottom of the cylinder body 8. A contoured stopper 12 is provided at the top end of the L-shaped cylinder body placement platform 1 for abutting against the side of the cylinder body 8.

[0038] Specifically, the cylinder body placement platform 1 is an L-shaped structure, the bottom end of the L-shaped cylinder body placement platform 1 is rotatably connected to the base 4 through a support, and a fixing seat 11 is set on the bottom end of the L-shaped cylinder body placement platform 1. The fixing seat 11 is the designated placement position of the cylinder body 8, so as to facilitate manual hanging of the cylinder body 8 and avoid the cylinder body 8 from being placed randomly. In addition, in order to further ensure that the cylinder body 8 does not overturn during the rotation process, a clamping block 3 is set on the side of the fixing seat 11 away from the top end of the L-shaped cylinder body placement platform 1, and a contour block 12 is set on the top end of the L-shaped cylinder body placement platform 1. The shape of the contour block 12 is adapted to the shape of the side of the cylinder body 8. In this way, after the cylinder body 8 is hung on the fixing seat 11, as shown in FIG. Figure 3 As shown, the left side of the clamping block 3 can be in contact with the top end of the L-shaped cylinder body placement platform 1, and the clamping block 3 is located on the right side of the cylinder body 8. The clamping block driving mechanism 2 drives the clamping block 3 to move leftward until the clamping block 3 clamps the bottom of the cylinder body 8, and then the gear driving mechanism 5 is started to drive the L-shaped cylinder body placement platform 1 to rotate. During the rotation process, Figure 4 As shown, the bottom of the cylinder body 8 is clamped by the clamping block 3, and the side of the cylinder body 8 is against the top end of the L-shaped cylinder body placement platform 1, which can effectively prevent the cylinder body 8 from overturning.

[0039] Considering the specific structure of the clamping block driving mechanism 2, the screw drive has the characteristics of good impact resistance, high reliability and high precision. Figure 1 and Figure 2 The clamping block driving mechanism 2 includes a clamping block 3 driving motor and a screw rod. The clamping block 3 driving motor is arranged at the bottom end of the L-shaped cylinder body placement platform 1 and its output shaft is connected to the screw rod. The clamping block 3 is sleeved on the screw rod and is threadedly connected to it. In this way, when the clamping block 3 driving motor is started, its output shaft drives the screw rod to rotate. The screw rod is threadedly connected to the clamping block 3, and the rotational motion can be converted into linear motion to drive the clamping block 3 to move toward or away from the cylinder body 8.

[0040] Optionally, the output shaft of the clamping block 3 driving motor is set toward the contour stopper 12, so that a clamping force is formed between the clamping block 3 sleeved on the output shaft of the clamping block 3 driving motor and the contour stopper 12, which is used to firmly clamp the cylinder body 8, thereby effectively fixing the cylinder body 8 and preventing the cylinder body 8 from overturning during rotation.

[0041] Considering the specific structure of the gear drive mechanism 5, based on the above embodiment, please refer to Figure 2 The gear drive mechanism 5 includes a gear drive motor 51, a drive rod 52 and a transmission member 53. The drive rod 52 is rotatably arranged on the base 4 and gears 6 are sleeved on both ends of the drive rod 52. The gear drive motor 51 is arranged on the base 4, and its output shaft is connected to the drive rod 52 through the transmission member 53.

[0042] Specifically, a left gear drive mechanism 5 is arranged at the lower left side of the bottom end of the L-shaped cylinder body placement platform 1, and a right gear drive mechanism 5 is arranged at the lower right side of the top end. Both the left gear drive mechanism 5 and the right gear drive mechanism 5 are composed of a drive motor, a drive rod 52 and a transmission member 53. Both ends of the drive rod 52 are rotatably fixed on the base 4 through a support, and both ends of the drive rod 52 are sleeved with gears 6. Each gear 6 in the left gear drive mechanism 5 is connected to the bottom end of the L-shaped cylinder body placement platform 1 through a chain 7, and each gear 6 in the right gear drive mechanism 5 is also connected to the top end of the L-shaped cylinder body placement platform 1 through a chain 7. In this way, the two gear drive motors 51 located on the left and right sides are started at the same time, and their output shafts rotate and drive the drive rod 52 to rotate through the transmission member 53, so as to drive all the gears 6 to rotate in the same direction, thereby realizing the rotation of the cylinder body placement platform 1.

[0043] To ensure that the cylinder 8 rotates smoothly, based on the above embodiment, please refer to Figure 1 and Figure 2 , the driving rods 52 in the two gear driving mechanisms 5 are parallel to each other and are arranged along the length direction of the two ends of the cylinder body placement platform 1. Specifically, the two supports are symmetrically arranged at the four corners of the base 4, the two ends of the left driving rod 52 are rotatably arranged on the two left supports, and the two ends of the right driving rod 52 are rotatably arranged on the two right supports. The left driving rod 52 and the right driving rod 52 are arranged in parallel. In this way, the bottom end of the L-shaped cylinder body placement platform 1 is connected to the gears 6 at the two ends of the left driving rod 52 through two symmetrical chains 7, and the top end of the L-shaped cylinder body placement platform 1 is connected to the gears 6 at the two ends of the right driving rod 52 through two symmetrical chains 7, which can avoid the chain 7 from driving the cylinder body placement platform 1 to tilt during the rotation process, thereby ensuring that the cylinder body placement platform 1 rotates smoothly, and then ensuring that the cylinder body 8 rotates smoothly.

[0044] The output shaft of the gear driving mechanism 5 is vertically arranged with respect to the driving rod 52 . To ensure the transmission of driving force between the gear driving mechanism 5 and the driving rod 52 , a transmission member 53 is arranged between the output shaft of the gear driving mechanism 5 and the driving rod 52 .

[0045] Optionally, the transmission member 53 adopts a worm gear structure with a high transmission ratio and a compact structure. The worm is connected to the output shaft of the gear drive motor 51, and the worm wheel is sleeved on the drive rod 52 and meshingly connected with the worm, so that the gear drive mechanism 5 has the characteristics of high transmission ratio and compact structure.

[0046] Alternatively, the transmission member 53 uses a first bevel gear and a second bevel gear with good stability and strong load-bearing capacity. The first bevel gear is sleeved on the output shaft of the gear drive motor 51, and the second bevel gear is sleeved on the drive rod 52, and the two are meshed and connected to ensure smooth transmission of the gear drive mechanism 5.

[0047] In addition, the transmission member 53 can also be selected as a universal joint. Specifically, the output shaft of the gear drive motor 51 is connected to an interface of the universal joint, and the drive rod 52 is divided into two sections, and the two ends are respectively connected to the two interfaces of the universal joint to achieve the vertical drive rod 52 and the output shaft of the gear drive motor 51. Rotate simultaneously.
