Description

Technical Field

[0001] This application relates to the field of pulling devices, and more specifically, to a roller pulling device for an engine cylinder block. Background Technology

[0002] The cylinder block is the main body of the engine. It connects the cylinders and crankcase into one unit and serves as the supporting frame for mounting pistons, crankshafts, and other parts and accessories.

[0003] In related technologies, the engine cylinder block inspection process is carried out on a roller conveyor, which is equipped with a push-pull device. A platform is placed on the roller conveyor, and the engine cylinder block is placed on the platform. The push-pull device pushes and pulls the platform to achieve the purpose of pushing and pulling the cylinder block. In actual use, the hook lock at the end of the push-pull device is connected to one end of the platform to push or pull the platform. During the inspection process, it is necessary to separate the hook lock from the platform to avoid affecting the inspection of the engine cylinder block. However, at this time, it is difficult for the push-pull device hook lock to be automatically unhooked, and manual assistance is required to unhook it. That is, a tool is used to pry the hook lock to separate it from the platform, which increases the number of steps in the engine cylinder block inspection process to a certain extent. Summary of the Invention

[0004] To overcome the shortcomings of the existing system, this application provides a roller conveyor pulling device for engine cylinder blocks, which can solve the problem that the existing push-pull device cannot achieve automatic disengagement from the platform.

[0005] The technical solution adopted by this application embodiment to solve its technical problem is: a roller conveyor pulling device for an engine cylinder block, including a roller conveyor mechanism, a push-pull mechanism and a lifting mechanism fixedly installed on the roller conveyor mechanism, a rotating shaft rotatably connected to one end of the push-pull mechanism, a push-pull block fixedly connected to the outer wall of the rotating shaft, a flat gear fixedly connected to one end of the rotating shaft, a flat tooth provided at the top of the lifting mechanism, the flat gear being able to mesh with the flat tooth, and a stop block fixedly installed at one end of the push-pull mechanism, the stop block being located directly below the rotating shaft and being able to contact and limit the push-pull block.

[0006] In one specific implementation, the roller conveyor mechanism includes two supports, two rollers, and a support plate. The two supports are arranged parallel to each other, and the support plate and the two rollers are both mounted on the two supports and arranged parallel to each other. The push-pull mechanism and the lifting mechanism are respectively fixedly installed on the top and side wall of the support plate.

[0007] In one specific implementation, both roller conveyors are provided with grooves at their tops, and the two grooves are open on their facing surfaces. Several conveying rollers are rotatably connected to the facing sidewalls of both roller conveyors.

[0008] In one specific implementation, the push-pull mechanism includes a first cylinder and an L-shaped block. The first cylinder is fixedly installed on the top of the support plate. The side wall of the L-shaped block is fixedly connected to the output shaft of the first cylinder. A groove is provided on one side wall of the L-shaped block, and the groove is open at both the top and bottom.

[0009] In one specific implementation, one end of the rotating shaft is rotatably connected to one end of the groove, and the other end of its sidewall rotatably passes through the other end of the groove. The stop block is fixedly installed on both ends of the groove.

[0010] In one specific implementation, the lifting mechanism includes a vertically arranged mounting plate, a second cylinder, and a lifting plate. The mounting plate is fixedly installed on one end side wall of a support plate, the second cylinder is fixedly installed on the side wall of the mounting plate, and the lifting plate is horizontally installed on the output shaft of the second cylinder, with flat teeth arranged on the top of the lifting plate.

[0011] In one specific implementation, a roller is installed at the bottom of the L-shaped block, and the roller is rotatably mounted on the support plate.

[0012] The advantages of this embodiment are: a rotatable shaft is provided on the roller conveyor mechanism, and the push-pull block is installed on the outer wall of the shaft, which can rotate around the center of the shaft. One end of the shaft is connected to a flat gear. After the flat gear contacts the rising flat gear, it will cause the shaft to rotate, thus causing the push-pull block to rotate to the other side, thereby pulling the platform to reset. During the reset process, the flat gear moves on the flat gear, causing the shaft to rotate counterclockwise, and thus the push-pull block rotates counterclockwise, thereby achieving the purpose of automatic unhooking.

Detailed Implementation

[0020] The technical solution in this application embodiment is to solve the problem that the existing push-pull device cannot automatically disengage from the platform. The overall idea is as follows:

[0021] Example 1:

[0022] Please see Figure 1-6 A roller conveyor pulling device for engine cylinder blocks, comprising:

[0023] The roller conveyor mechanism 10 has a push-pull mechanism 110 and a lifting mechanism 120 fixedly installed on it. One end of the push-pull mechanism 110 is rotatably connected to a rotating shaft 130. A push-pull block 140 is fixedly connected to the outer wall of the rotating shaft 130. One end of the rotating shaft 130 is fixedly connected to a flat gear 150. The top of the lifting mechanism 120 is provided with a flat gear. The flat gear 150 can mesh with the flat gear. One end of the push-pull mechanism 110 is fixedly installed with a stop block 160. The stop block 160 is located directly below the rotating shaft 130 and can contact and limit the movement of the push-pull block 140.

[0024] When set up, since the spur gear 150 can mesh with the spur gear, the spur gear 150 and the spur gear are on the same line. That is, the push-pull mechanism 110 pushes the rotating shaft 130 to move, so that the spur gear 150 can contact the spur gear and mesh, thereby causing the spur gear 150 to move with the spur gear, so that the rotating shaft 130 rotates and drives the push-pull block 140 to rotate.

[0025] See Figure 1 and 4 The roller conveyor mechanism 10 includes two supports 100, two roller conveyors 200 and a support plate 300. The two supports 100 are arranged in parallel to each other. The support plate 300 and the two roller conveyors 200 are both installed on the two supports 100 and are arranged in parallel to each other. The push-pull mechanism 110 and the lifting mechanism 120 are respectively fixedly installed on the top and side wall of the support plate 300.

[0026] Both roller conveyors 200 have grooves at their tops, and the two grooves are open on their facing surfaces. Several conveying rollers are rotatably connected to the facing sidewalls of both roller conveyors 200.

[0027] Specifically, the connection between the support plate 300 and the roller conveyor 200 and the two supports 100 is the prior art. The bottom of the existing platform (such as the platform described in patent number CN209615418U) is placed on the conveyor rollers on both sides, and the front and rear side walls of the platform are respectively in two slide grooves. The two slide grooves can limit the platform so that the platform will not move in the front and rear directions when it moves on the conveyor rollers.

[0028] participate Figure 1 and 5 The push-pull mechanism 110 includes a first cylinder 1110 and an L-shaped block 1120. The first cylinder 1110 is fixedly installed on the top of the support plate 300. The side wall of the L-shaped block 1120 is fixedly connected to the output shaft of the first cylinder 1110. A groove 1130 is provided on one side wall of the L-shaped block 1120, and the groove 1130 is set with openings at the top and bottom.

[0029] In the specific setup, the first cylinder 1110 is installed in the existing technology. The first cylinder 1110 extends and retracts, driving the L-shaped block 1120 to move horizontally, thereby enabling the push-pull block 140 to move horizontally.

[0030] See Figure 4 and 6 One end of the rotating shaft 130 is rotatably connected to one end of the groove 1130, and the other end of its side wall rotatably passes through the other end of the groove 1130. The stop block 160 is fixedly installed on both ends of the groove 1130.

[0031] The stop block 160 is set to limit the push-pull block 140. When the push-pull block 140 rotates to the left side of the pivot 130, it contacts the left side of the stop block 160, thus limiting the push-pull block 140 during the pushing process. Conversely, when the push-pull block 140 rotates to the right side of the pivot 130, it contacts the right side of the stop block 160, thus limiting the push-pull block 140 during the pulling process.

[0032] See Figure 1 and 5 The lifting mechanism 120 includes a vertically arranged mounting plate 1210, a second cylinder 1220, and a lifting plate 1230. The mounting plate 1210 is fixedly installed on one side wall of the support plate 300, the second cylinder 1220 is fixedly installed on the side wall of the mounting plate 1210, and the lifting plate 1230 is horizontally installed on the output shaft of the second cylinder 1220. A flat tooth is arranged on the top of the lifting plate 1230.

[0033] Specifically, the connection between the second cylinder 1220 and the mounting plate 1210 is existing technology. The second cylinder 1220 is a three-axis cylinder, with all three axes connected to the bottom of the lifting plate 1230, increasing the contact area with the lifting plate 1230 and ensuring the structural stability of the lifting plate 1230. Furthermore, the extension and retraction of the first cylinder 1110 and the second cylinder 1220 are controlled by an existing PLC controller.

[0034] See Figure 5 The bottom of the L-shaped block 1120 is equipped with a roller 20, which rolls on the support plate 300.

[0035] It should be noted that the roller 20 consists of a central shaft, two circular wheels, and two collars. The two circular wheels are fixedly connected to the two end side walls of the central shaft, and the two collars are fixedly installed at the bottom of the L-shaped block 1120. The central shaft passes through the two collars, allowing the two circular wheels to roll on the support plate 300. In addition, the structure of the roller 20 is not limited to the above structure. It can also be an existing fixed pulley. The bottom of the fixed pulley can be installed at the bottom of the L-shaped block 1120, allowing the wheels of the fixed pulley to roll on the support plate 300. Thus, the roller 20 can achieve the purpose of auxiliary support for the L-shaped block 1120.

[0036] When using this application: the platform is placed on two roller conveyors 200 and simultaneously in contact with the conveyor roller below. Then, the engine block can be hoisted onto the platform. The first cylinder 1110 is controlled to run, causing the first cylinder 1110 to push the L-shaped block 1120 to move to the right. At this time, the push-pull block 140 is located to the left of the rotating shaft 130. After the push-pull block 140 contacts the platform, it will push the platform to move to the right. When it moves to the designated position, it stops. Then, the first cylinder 1110 is controlled to reset. After the reset is completed, the engine block can be inspected.

[0037] Furthermore, after the test is completed, the engine block needs to be pulled back. At this time, the push-pull block 140 is located on the left side of the rotating shaft 130. Then, the first cylinder 1110 and the second cylinder 1220 are started, causing the L-shaped block 1120 to move to the right. At the same time, the lifting plate 1230 drives the flat gear to move to the height that can mesh with the flat gear 150. As the L-shaped block 1120 moves to the right, the flat gear 150 rolls to the right on the flat gear, causing the rotating shaft 130 to rotate clockwise, thereby causing the push-pull block 140 to rotate to the right side of the rotating shaft 130.

[0038] Furthermore, since the push-pull block 140 is located to the right of the rotating shaft 130 at this time, it will be squeezed when it contacts the left side wall of the platform, causing the push-pull block 140 to rotate to the left by a certain angle. After passing the left side wall of the platform, it will reset. Then, the first cylinder 1110 is controlled to drive the L-shaped block 1120 to reset, so the push-pull block 140 will pull the platform to the left. At the same time, the position of the flat gear does not change, so when the flat gear 150 rolls to the left on the flat gear, the rotating shaft 130 rotates counterclockwise, causing the push-pull block 140 to flip to the left. At this time, the push-pull block 140 will squeeze the platform to the left until the push-pull block 140 separates from the bottom left side of the platform, thus achieving the purpose of automatic unhooking. Then the L-shaped block 1120 continues to move and resets. At the same time, the push-pull block 140 also rotates to the left side of the rotating shaft 130, and then the engine block is lifted away, so that the next engine block can be inspected.

[0039] It should be noted that the specific model and specifications of the first cylinder 1110 and the second cylinder 1220 need to be selected and determined according to the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

[0040] The power supply and operating principle of the first cylinder 1110 and the second cylinder 1220 are clear to those skilled in the art and will not be described in detail here.

[0041] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the scope of protection of this invention.
