Description

Technical Field

[0001] The invention relates to the technical field of spark plug processing, in particular to an automatic press-fitting mechanism for a spark plug sheath. Background Art

[0002] During the manufacturing and assembly process of automobile engines and other equipment, the installation of spark plug boots is one of the key links. As an important component to protect the spark plugs and ensure their normal operation, the installation quality of the spark plug boots directly affects the performance and reliability of the engine. The traditional manual press-fitting method is not only inefficient and difficult to meet the needs of large-scale production, but also manual operation cannot ensure the consistency of the force and position accuracy of each press-fit, which can easily lead to damage to the boots or loose installation, thereby affecting the overall performance of the engine and even causing safety hazards.

[0003] With the continuous development of industrial automation technology, a number of automatic press-fitting mechanisms for spark plug sleeves have gradually appeared on the market, aiming to improve production efficiency and ensure press-fitting quality. However, existing automatic press-fitting mechanisms for spark plug sleeves still have many defects. Although existing mechanisms have achieved automation to a certain extent, they still require manual placement of the sleeves one by one. This not only increases labor costs, but also, due to the randomness of manual operation, it is difficult to ensure the stability and consistency of the production rhythm, limiting further improvements in production efficiency and seriously insufficient automation. Some mechanisms have obvious deficiencies in the feeding of sleeves, making it difficult to achieve intermittent and orderly entry of sleeves into the placement slot. Multiple sleeves often enter the placement slot at the same time, resulting in press-fitting confusion and errors. This not only wastes raw materials, but also increases the defective rate and increases production costs.

[0004] Therefore, the development of a highly automated, high-precision, stable feeding, and automatic resetting spark plug sheath automatic pressing mechanism has become a technical problem that needs to be urgently solved in the current automobile manufacturing and related industries.

[0012] As a further preferred embodiment of the present technical solution, a fixed plate is fixedly installed on the other side of the slide frame, a moving wheel is provided at one end of the fixed plate, and the positions of the moving wheel and the inclined surface of the trapezoidal block correspond to each other.

[0013] As a further preferred embodiment of the present technical solution, a gear is rotatably connected to the bottom of the tilting frame, and a first gear rod and a second gear rod are meshedly connected on both sides of the gear. One end of the first gear rod is fixedly connected to the first vertical rod, and the first vertical rod is fixedly installed at the bottom of the sliding frame. The second gear rod is slidably installed at the bottom of the tilting frame, and one end is fixedly connected to the second vertical rod.

[0014] As a further optimization of the present technical solution, mounting seats are fixedly connected on both sides of the placing table, a movable rod is connected to the surface of the mounting seat through rotation of the mounting seat, a flip clamp is fixedly connected to the outer wall of the movable rod, a torsion spring is arranged between the flip clamp and the mounting seat, one end of the flip clamp is fixedly connected to a pressure plate, one end of the movable rod is fixedly connected to a V-shaped rod, a push rod is arranged on the surface of the V-shaped rod, and the two push rods are respectively installed on the first vertical rod and the second vertical rod.

[0015] Compared with the existing technology, it has the following beneficial effects:

[0016] Automated operation improves production efficiency: The entire pressing process controls the movement of each component through the opening and closing of the cylinder, realizing the automated operation of the sleeve from entering the placement groove to being pressed into the cylinder head mounting hole. There is no need to manually place the sleeves one by one and perform press-fitting operations, which greatly reduces manual intervention and saves labor costs. The mechanism can continuously and repeatedly complete the press-fitting action of the sleeve according to the set program. The various components work together, so that the sleeve can intermittently and orderly enter the placement groove and be press-fitted, which can meet the needs of large-scale production and significantly improve production efficiency.

[0017] Precise control to ensure the quality of pressing: the first cylinder drives the sliding frame and the rotating plate to move, so that the placement slot of the rotating plate can be accurately moved to the position corresponding to the discharge port of the tilting frame, ensuring that the sleeve can smoothly enter the placement slot, providing a basis for subsequent precise pressing, and the second cylinder drives the lifting seat and the pressure rod to move, thereby pressing the sleeve into the mounting hole of the cylinder head. By controlling the movement of the second cylinder, the downward pressure and downward pressure distance of the pressure rod can be accurately controlled to avoid damage to the sleeve or loose installation due to excessive or insufficient pressing force, thereby ensuring the quality of pressing. When the pressed part is about to completely press the sleeve into the cylinder head, the first cylinder is used to drive the rotating plate away from the sleeve and cylinder head, so that the rotating plate is separated from the sleeve and cylinder head, and then the second cylinder is opened to drive the pressure rod to completely press the sleeve in. This step-by-step pressing method avoids interference of the rotating plate with the sleeve and cylinder head during the pressing process, further improving the accuracy and stability of pressing.

[0018] The structure is ingenious, and intermittent feeding is realized: when the slide frame moves, it drives the fixed plate and the moving wheel to move synchronously, and the moving wheel pushes the trapezoidal block to move, which in turn drives the slide rod, the disc, and the partition plate to move synchronously and compress the third damping spring, so that the partition plate moves out of the inclined frame, allowing the sleeve to enter the placement slot; when the slide frame moves in the opposite direction, the partition plate and other components move and reset under the elastic force of the third damping spring, forming a barrier to the next group of sleeves. This ingenious structural design realizes the intermittent entry of the sleeve into the placement slot, ensuring that only one sleeve enters the placement slot for press-fitting at a time, avoiding confusion and press-fitting errors caused by multiple sleeves entering at the same time. The design of the third damping spring makes the movement of the partition plate have a certain buffer and stability, which can ensure that During the movement of the carriage, the partition plate can accurately block or release the sleeve, ensuring the stability and reliability of feeding, thereby improving the working stability of the entire pressing mechanism. After the sleeve completely enters the mounting hole of the cylinder head, the second cylinder drives the lifting seat and the pressure rod to move upward and reset; when the first cylinder pushes the sliding frame to move and reset, the rotating plate rotates and resets under the elastic force of the first damping spring. The automatic reset function of each component enables the mechanism to quickly return to its initial state, preparing for the next pressing, and ensuring the continuous and normal operation of the mechanism. The automatic reset function avoids failures such as jamming and collision caused by failure to reset components, reduces equipment downtime, reduces maintenance costs, and improves equipment service life and reliability.

[0019] By controlling the synchronous outward or inward movement of the first vertical rod and the second vertical rod, the automatic opening and closing of the pressure plate can be achieved. This automated operation method greatly simplifies the manual operation process, reduces the time and energy required for manual placement and fixing of the cylinder head, and improves overall work efficiency. For example, in the mass production process, workers only need to place the cylinder head on the placement table, and then control the movement of the vertical rod through the control system to quickly complete the fixing of the cylinder head. There is no need to manually adjust the pressure plate one by one. The movement of the vertical rod can quickly drive the movement of related components, so that the pressure plate can complete the opening and closing action in a short time. This rapid response capability enables the equipment to adapt to the high-speed and continuous production rhythm, reduces the waiting time in the production process, and further improves production efficiency.

DETAILED DESCRIPTION

[0030] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] Example 1: Combination Figures 1-8As shown, the present invention provides a technical solution: an automatic press-fitting mechanism for a spark plug sheath, comprising a frame 1, a placement table 2 fixedly mounted on the top of the frame 1, a support base 3 fixedly mounted on the frame 1 is provided on one side of the placement table 2, and a press-fitting assembly 4 is provided on the top of the support base 3;

[0032] The press-fitting assembly 4 includes a support frame 41 fixedly mounted on the top of the support seat 3, a placement groove 45 is provided on one side of the support frame 41, a tilting frame 413 fixedly mounted on the frame 1 is provided on one side of the placement groove 45, a pressing piece mounted on the frame 1 is provided on the top of the placement groove 45, a sliding frame 43 is provided on the surface of the support frame 41, and a rotating plate 44 is rotatably mounted on one side of the sliding frame 43, a first cylinder 410 is fixedly mounted on the surface of the support frame 41, and the output end of the first cylinder 410 is fixedly connected to the sliding frame 43, and the sliding frame 4 is driven by opening the first cylinder 410. 3. The rotating plate 44 moves toward one side of the tilting frame 413, so that the placement groove 45 of the rotating plate 44 moves to the position corresponding to the discharge port of the tilting frame 413. After the sheath in the tilting frame 413 enters the placement groove 45, the pressing member pushes the sheath toward the side of the cylinder head, and when moving downward, it can push the rotating plate 44 downward. When the pressing member is about to completely press the sheath into the cylinder head, the first cylinder 410 is turned on to drive the sliding frame 43 and the rotating plate 44 to move away from the side of the tilting frame 413, thereby separating the rotating plate 44 from the sheath and the cylinder head.

[0033] A slide groove 42 is formed on the surface of the support frame 41, and a slide rod 48 is fixedly mounted on the inner wall of the slide groove 42. The slide frame 43 is slidably mounted on the slide groove 42 and the slide rod 48. A second damping spring 49 is provided on one side of the slide frame 43 and is sleeved on the slide rod 48. When the first cylinder 410 drives the slide frame 43 to move, the slide frame 43 can slide on the slide groove 42 and the slide rod 48. When the slide frame 43 moves to the side away from the tilting frame 413, the second damping spring 49 can be compressed, and the second damping spring 49 is used for buffering, thereby ensuring a smooth and safe entire press-fitting process.

[0034] The tilting frame 413 is designed to tilt toward one side of the placement slot 45 so that the protective cover can enter the placement slot 45 more easily. On one side of the tilting frame 413, the sliding frame 43 is fixedly installed and equipped with a crossbar 46. A first damping spring 47 is cleverly arranged between the crossbar 46 and the rotating plate 44. When the tilting frame 413 tilts toward the placement slot 45, it not only facilitates the entry of the protective cover, but also, under the elastic force of the first damping spring 47, the rotating plate 44 can be driven to move upward and return to its initial position.

[0035] The design of the pressed part includes slide rails 432 fixedly mounted on both sides of the surface of the frame 1, and a lifting seat 433 is slidably connected to the slide rails 432 to ensure that the lifting seat 433 can move freely on the slide rails 432. A second cylinder 434 is also fixedly mounted on the top of the frame 1, and its output end is fixedly connected to the lifting seat 433. A pressure rod 435 is fixedly mounted on the bottom of the lifting seat 433, and the position of the pressure rod 435 corresponds to the placement groove 45. By activating the second cylinder 434, the lifting seat 433 can move upward along the slide rails 432. As the lifting seat 433 rises, the pressure rod 435 will also move downward, thereby pushing the sleeve on the placement groove 45 to move to one side of the cylinder head. This series of actions ultimately realizes the pressing of the sleeve into the mounting hole of the cylinder head, ensuring the correct installation of the sleeve.

[0036] At the outer end of the tilting frame 413, there is a sleeve 414 fixedly connected, and there is a sliding connection between the inner wall of the sleeve 414 and the slide bar 415, one end of the slide bar 415 is firmly connected to the disc 417, and the other end of the disc 417 is connected to the partition plate 416, and the partition plate 416 is slidably installed on the tilting frame 413, and a third damping spring 418 is provided between the disc 417 and the sleeve 414. It is sleeved on the slide bar 415, and the other end of the slide bar 415 is fixedly connected to the trapezoidal block 419. On the other side of the slide frame 43, a fixed plate 411 is fixedly installed, and one end of the fixed plate 411 is provided with a moving wheel 412. The inclined surface positions of the moving wheel 412 and the trapezoidal block 419 correspond to each other. When the slide frame 43 moves to the side away from the tilting frame 413, the slide frame 43 can drive the fixed plate 411 and the moving wheel 412 to move synchronously, so that When the moving wheel 412 moves to one side, it can push the trapezoidal block 419 to move to the side away from the sleeve 414. The movement of the trapezoidal block 419 will drive the sliding rod 415, the disc 417, and the partition plate 416 to move synchronously and compress the third damping spring 418. This process causes the partition plate 416 to move out of the inclined frame 413 and no longer form an obstacle to the sheath in the inclined frame 413. In this way, the sheath can smoothly enter the placement groove 45. When the sliding frame 43, the fixed plate 411, and the moving wheel 412 move to one side of the inclined frame 413, the partition plate 416, the disc 417, the sliding rod 415, and the trapezoidal block 419 move and reset under the elastic force of the third damping spring 418. After resetting, the partition plate 416 will block the next group of sheaths, thereby realizing the control of the sheath intermittently entering the placement groove 45. This process can be repeated continuously to ensure the orderly placement of the sheaths.

[0037] The bottom of the tilting frame 413 is connected to the gear 421 by rotation. The two sides of the gear 421 are respectively meshed with the first gear rod 422 and the second gear rod 423. One end of the first gear rod 422 is fixedly connected to the first vertical rod 420, and the first vertical rod 420 is fixedly installed at the bottom of the slide 43. The second gear rod 423 is slidably installed at the bottom of the tilting frame 413 and one end is fixedly connected to the second vertical rod 424. When the slide 43 moves to the side away from the tilting frame 413, the slide 43 can drive the first vertical rod 420 to move synchronously. The movement of the first vertical rod 420 will drive the first gear rod 422 to move synchronously, thereby causing the first gear rod 422 to drive the meshed gear 421 to rotate, and the rotation of the gear 421 will This causes the second gear rod 423 and the second vertical rod 424 engaged therewith to move in opposite directions. This design ensures that the movement of the slide 43 can be achieved through the gear 421 transmission mechanism. The first cylinder 410 drives the slide 43, the fixed plate 411, and the moving wheel 412 to move synchronously. When the moving wheel 412 moves toward the side away from the tilting frame 413, it can push the trapezoidal block 419 to move away from the tilting frame 413, so that the trapezoidal block 419 drives the slide rod 415, the disc 417, and the partition plate 416 to move synchronously, and compresses the third damping spring 418, so that the partition plate 416 no longer forms an obstacle to the sheath in the tilting frame 413, so that the sheath can enter the placement groove 45 on the rotating plate 44, thereby achieving the placement of the sheath.

[0038] In the embodiment of the present invention, by starting the first cylinder 410, the sliding frame 43 and the rotating plate 44 will move to one side of the tilting frame 413, causing the placement groove 45 on the rotating plate 44 to move to the discharge port of the tilting frame 413, and the positions correspond to each other. Subsequently, the sleeve in the tilting frame 413 will enter the placement groove 45. Then, by activating the second cylinder 434, the lifting seat 433 moves upward along the slide rail 432, thereby driving the pressure rod 435 to move downward. The pressure rod 435 will push the sleeve on the placement groove 45 to move to one side of the cylinder head, thereby pressing the sleeve into the mounting hole of the cylinder head. When the sleeve is about to completely enter the cylinder head, the first cylinder 410 is started again. The sliding frame 43 and the rotating plate 44 will move away from the side of the tilting frame 413, so that the rotating plate 44 is separated from the sleeve and the cylinder head. Then, the second cylinder 434 will continue to operate to move the pressure rod 435 downward, pushing the sleeve completely into the mounting hole of the cylinder head. When the sleeve is completely in the mounting hole of the cylinder head, the second cylinder 434 will drive the lifting seat 433 and the pressure rod 435 to move upward and reset. At the same time, under the elastic action of the first damping spring 47, the rotating plate 44 will rotate and reset. Finally, the first cylinder 410 will push the sliding frame 43 to move to the side of the sliding frame 43, the fixed plate 411, the moving wheel 412, and the rotating plate 44 close to the tilting frame 413 and reset.

[0039] In the process of the slide 43 moving to the side away from the tilting frame 413, the slide 43 can drive the fixed plate 411 and the moving wheel 412 to move synchronously. When the moving wheel 412 moves to one side, it pushes the trapezoidal block 419 away from the side of the sleeve 414, and then the trapezoidal block 419 drives the slide bar 415, the disc 417, and the partition plate 416 to move synchronously and compress the third damping spring 418. In this way, the partition plate 416 will move out of the tilting frame 413 and no longer The sheaths in the tilting frame 413 form a blockage, allowing the sheaths to enter the placement groove 45. When the sliding frame 43, the fixed plate 411, and the moving wheel 412 move toward one side of the tilting frame 413, the partition plate 416, the disc 417, the slide rod 415, and the trapezoidal block 419 move and reset under the elastic force of the third damping spring 418, so that the partition plate 416 forms a block for the next group of sheaths. Through such reciprocating action, the sheaths can be controlled to intermittently enter the placement groove 45.

[0040] Example 2: Combination Figure 9 As shown, on the basis of Example 1, mounting seats 425 are fixedly connected on both sides of the placement table 2, and a movable rod 426 is rotatably connected to the surface of the mounting seat 425 through the mounting seat 425, and a flip clamp 427 is fixedly connected to the outer wall of the movable rod 426, and a torsion spring 429 is arranged between the flip clamp 427 and the mounting seat 425, and a pressure plate 428 is fixedly connected to one end of the flip clamp 427, and a V-shaped rod 430 is fixedly connected to one end of the movable rod 426, and a push rod 431 is arranged on the surface of the V-shaped rod 430, and the two push rods 431 are respectively mounted on the first vertical rod 420 and the second vertical rod 424, and under the elastic force of the torsion spring 429, the flip clamp 427 and the pressure plate 428 can be pushed to rotate toward the side of the surface of the placement table 2, so that the pressure plate 428 can press and position the cylinder head located on the placement table 2, thereby fixing the cylinder head on the placement table 2.

[0041] In the embodiment of the present invention, when the first vertical rod 420 and the second vertical rod 424 move outward synchronously, the first vertical rod 420 and the second vertical rod 424 can push the push rod 431 to move outward, so that the push rod 431 drives the V-shaped rod 430 to rotate, so that the V-shaped rod 430 drives the movable rod 426, the flip clamp 427, and the pressure plate 428 to move and rotate outward, so that the two pressure plates 428 can be opened. Then, after the cylinder head is placed on the placement table 2, the first vertical rod 420 and the second vertical rod 424 are controlled to move inward synchronously.

[0042] The first vertical rod 420 and the second vertical rod 424 drive the V-shaped rod 430 to rotate inward, so that the V-shaped rod 430 drives the movable rod 426, the flip clamp 427, and the pressure plate 428 to rotate inward. At this time, under the elastic force of the torsion spring 429, the pressure plate 428 presses down and fixes the cylinder head in position.

[0043] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
