Description

Technical Field

[0001] The invention relates to the technical field of engine production, in particular to an engine tightening device and a protective cover. Background Art

[0002] In the process of tightening bolts of engines, manual operation is currently generally relied on, and torque wrenches are used to tighten bolts one by one. However, it is easy to leak when tightening bolts manually, which may cause vibration and abnormal noise when the engine is running. In severe cases, it may even cause loosening and falling of components, causing serious mechanical failures. Wrong tightening is also a common problem when tightening bolts manually, which may cause incoordination between engine components, thereby affecting its overall performance and reliability. Inadequate torque is also a major hidden danger when tightening bolts manually. Torque is an important indicator of the tightness of bolt connection. If the torque is insufficient, the bolt connection will not achieve the expected tightening effect, which may cause the gap between engine components to be too large, thereby affecting its sealing and durability. On the contrary, if the torque is too large, it may cause problems such as bolt breakage or thread damage, which also poses a threat to the performance and safety of the engine. Inconsistent torque is also an unavoidable problem when tightening bolts manually. Due to factors such as differences in hand feel or fatigue during operation, workers may have different tightening torques between different bolts. This difference may cause uneven force between engine components, thereby affecting its overall performance and life. Summary of the invention

[0035] Example 1

[0036] Reference Figure 1 , which is the first embodiment of the present invention, provides an engine tightening device, comprising:

[0037] The mounting unit 100 includes a mounting seat 101, a sliding assembly 102 disposed on the mounting seat 101, and a mounting plate 103 disposed on the top of the sliding end of the sliding assembly 102;

[0038] The robot 200 is disposed on the top of the mounting plate 103;

[0039] The tightening unit 300 includes a driving component 301 disposed at the output end of the robot 200 and a fixing component 302 disposed at the output end of the driving component 301;

[0040] The linear unit 400 is disposed on the mounting seat 101 , and the moving end of the linear unit 400 is fixedly connected to the mounting plate 103 .

[0041] It should be noted that the mounting unit 100 includes a mounting base 101, and the device is fixedly mounted in the pre-working area by the mounting base 101. Because the device is too large and inconvenient to move, it needs to be fixed. The inner cavity of the mounting base 101 is fixedly connected with a sliding component 102, and the sliding component 102 can limit the movement trajectory of the mounting plate fixed to its mobile end;

[0042] The robot 200 is fixedly mounted on the top of the mounting plate 103 . The robot can drive the fixing assembly 302 in the tightening unit 300 to connect with the bolts on the engine, and then drive the fixing assembly 302 to rotate through the driving assembly 301 to tighten the bolts.

[0043] Specifically, the sliding assembly 102 includes a sliding rail 102a disposed at the bottom of the inner wall of the mounting seat 101, and a sliding bracket 102b slidably disposed on the top outer wall of the sliding rail 102a.

[0044] It should be noted that the sliding assembly 102 includes a sliding rail 102a fixedly installed on the bottom of the inner wall of the mounting base 101, and the number of the sliding rails 102a is at least two. A sliding bracket 102b is slidably connected to the top of the sliding rail 102a, and the mounting plate 103 is fixedly installed on the top of the sliding bracket 102b. Since the weight of the robot 200 is too large, multiple sliding rails 102a are required to provide multi-point support for the bottom of the sliding bracket 102b.

[0045] Specifically, the robot 200 includes a rotating base 201 disposed on the mounting plate 103, a first rotating component 202 disposed at the rotating end of the rotating base 201, a second rotating component 203 disposed at the rotating end of the first rotating component 202, and a third rotating component 204 disposed at the rotating end of the second rotating component 203.

[0046] Specifically, the robot 200 includes a rotating base 201 installed on the top of the mounting plate 103. The rotating base 201 can drive the horizontal rotation of the first rotating component 202, the second rotating component 203, and the third rotating component 204 above it. The fixing component 302 is connected to the bolt through the cooperation between the first rotating component 202, the second rotating component 203, and the third rotating component 204.

[0047] Specifically, the driving assembly 301 includes a mounting frame 301a disposed at the output end of the robot 200, and a tightening motor 301b disposed inside the mounting frame 301a.

[0048] It should be noted that the driving component 301 controls the mounting frame 301a installed at the output end of the robot 200, the mounting frame 301a is L-shaped, the tightening motor 301b is installed on the inner side of the mounting frame 301a, and the tightening motor 301b is a reciprocating motor.

[0049] Specifically, the fixing assembly 302 includes a mounting sleeve 302a disposed at the output end of the driving assembly 301, a screw 302b threadedly disposed on the mounting sleeve 302a, and a fitting groove 302c opened at the bottom of the mounting sleeve 302a.

[0050] It should be noted that the fixing assembly 302 includes a mounting sleeve 302a, and the side of the mounting sleeve 302a is threadedly connected with a screw 302b. By loosening the screw 302b, the mounting sleeve 302a can be removed from the driving assembly 301 and replaced. The fitting groove 302c is opened at the bottom of the mounting sleeve 302a, and the fitting groove 302c fits with the top outer wall of the bolt.

[0051] When in use, the engine is moved to one side of the equipment, and the relevant parameters such as the corresponding engine model, bolt installation position, torque size, quantity, etc. are preset in the system. The equipment is started, and the linear unit 400 drives the mounting plate 103 to move horizontally, thereby driving the robot 200 to move. After the robot 200 moves to the corresponding position, it drives the fixing component 302 to get stuck on the bolt, and the driving component 301 works, driving the fixing component 302 to rotate to tighten the bolt. The robot 200 automatically stops and searches for the next bolt to be tightened, and so on, until all the bolts are completed. After completing the operation, the robot will reset to the initial position, and the human worker only needs to ensure safety and check the normal operation of the robot 200.

[0052] In summary, the linear unit 400 drives the robot 200 to move, the robot 200 drives the fixing component 302 to be fixed on the bolt, and then drives the fixing component 302 to rotate through the driving component 301 to tighten the bolt. By presetting the corresponding parameters in advance, the robot will automatically find the next bolt to work after tightening a bolt. The whole process does not require human intervention, which solves the problems of missed tightening, wrong tightening, insufficient torque, and inconsistent torque caused by manual operation.

[0053] Example 2

[0054] Reference Figure 2 - Figure 4 The second embodiment of the present invention based on the first embodiment further provides a linear unit 400 including a motor housing 401 disposed at both ends of the mounting base 101, a first motor 402 disposed in the inner cavity of the motor housing 401, a transmission wheel 403 disposed at the output end of the first motor 402, and a transmission belt 404 sleeved on the two transmission wheels 403;

[0055] The transmission belt 404 and the mounting plate 103 are fixedly connected.

[0056] It should be noted that two motor housings 401 are fixedly connected to both ends of the mounting base 101, a first motor 402 is fixedly installed in the inner cavity of the motor housing 401, and two transmission wheels 403 are fixedly connected to the output end of the first motor 402. The outer walls of the two transmission wheels 403 are sleeved with transmission belts 404. When the transmission belts 404 work on the transmission wheels 403, they drive the mounting plate 103 to move.

[0057] When in use, first, a group of first motors 402 are started. This group of motors provides necessary power to drive the transmission wheel 403 connected thereto to start rotating. The transmission wheel 403 and the transmission belt 404 cooperate closely to ensure the effectiveness of power transmission.

[0058] The transmission belt 404 is tightly attached to the path below the mounting plate 103, and drives the mounting plate 103 to move through its own movement;

[0059] The mounting plate 103 serves as a platform for carrying the robot 200 and can ensure the stability of the robot 200 during movement. With the traction of the transmission belt 404, the mounting plate 103 moves along a preset route until the robot 200 is delivered to the working area.

[0060] In summary, through the coordinated work of the two first motors 402, the transmission wheel 403 is driven to rotate, and then the transmission belt 404 is driven to move, accurately driving the mounting plate 103 and the robot 200 thereon to move along a preset route. The entire process only requires presetting the movement length of the transmission belt 404 to achieve precise positioning of the robot 200.

[0061] Example 3

[0062] Reference Figure 2 - Figure 4 , which is a third embodiment based on the first embodiment of the present invention, comprises a linear unit 400 including a motor housing 401 disposed at one end of a mounting seat 101, a second motor 405 disposed in an inner cavity of the motor housing 401, a fixing bracket 406 disposed in the inner cavity of the mounting seat 101, and a threaded rod 407 disposed at an output end of the second motor 405;

[0063] The threaded rod 407 is rotatably connected to the fixing bracket 406 , and one end of the threaded rod 407 is rotatably connected to the mounting seat 101 .

[0064] It should be noted that one end of the mounting base 101 is fixedly connected to a motor housing 401, and the inner cavity of the motor housing 401 is fixedly connected to a second motor 405. The second motor 405 is specifically a reciprocating motor, which can drive the threaded rod 407 at its output end to achieve forward and reverse rotation. The threaded rod 407 and the mounting plate 103 are threadedly connected. When the threaded rod 407 rotates, it will drive the mounting plate 103 to move linearly.

[0065] When in use, after starting the second motor 405, the motor drives the threaded rod 407 to rotate. Since the threaded rod 407 is tightly connected to the mounting plate 103 through threads, the rotation of the threaded rod causes the mounting plate 103 to move linearly. As the threaded rod continues to rotate, the mounting plate 103 moves smoothly along a predetermined path and drives the robot 200 thereon to move to the working area.

[0066] In summary, the second motor 405 drives the threaded rod 407 to rotate, thereby driving the mounting plate 103 to move inside the chassis. Since the threaded rod 407 and the mounting plate 103 are threadedly connected, the mounting plate 103 can be precisely displaced by preset rotation numbers of the threaded rod 407, thereby achieving precise positioning of the robot 200.

[0067] Example 4

[0068] Reference Figure 1 , which is the fourth embodiment of the present invention, this embodiment provides a protective cover, including a wrapping unit 500, including a fixed cover body 501, and a shielding component 502 arranged on one side of the fixed cover body 501;

[0069] The moving unit 600 is specifically a universal wheel installed at the bottom of the fixed cover 501 .

[0070] The shielding assembly 502 includes a fixed rod 502a disposed on the top of the fixed cover body 501, and a shielding curtain 502b disposed on the outer wall of the fixed rod 502a.

[0071] It should be noted that the fixed cover 501 can completely wrap the engine tightening device, and a plurality of universal wheels are fixedly connected to the bottom of the fixed cover 501, and the universal wheels can facilitate the movement of the fixed cover. A fixed rod 502a is fixedly connected to the top of the fixed cover 501, and a shielding curtain 502b is provided on the outer wall of the fixed rod 502a. Pulling up the shielding curtain 502b can completely close the fixed cover 501.

[0072] When in use, push the fixed cover 501, align the opening of the fixed cover 501 with the engine tightening device, push the fixed cover 501 until it completely covers the engine tightening device, and then pull up the shielding curtain 502b to seal and protect the engine tightening device.

[0073] In summary, by providing a movable protective cover to wrap the engine tightening device, it is possible to prevent the engine tightening device from being exposed in a workshop when not in use and from absorbing dust due to static electricity.

[0074] It is important to note that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
