Description

Technical Field

[0001] The present invention relates to the technical field of special assembly equipment for air spring production sites, and more specifically, to an air spring support ring installation mechanism and an installation method applied to the air spring support ring installation mechanism. Background Art

[0002] At present, the automobile industry has widely promoted the use of air spring shock absorbers to replace traditional coil spring shock absorbers. Due to the unique structure of air springs, one of the processes in the production process is to install the support ring at a fixed height position inside the bladder skin. Among them, the support ring is made of carbon steel with a large outer diameter, and the bladder skin is made of rubber with a small inner diameter and an internal woven mesh. In the natural state, the diameter difference between the two is about 1.5 times, so it is impossible to install the support ring into the bladder skin by manpower or simple mechanisms. Therefore, in the current production process, there is an urgent need for a device that can automatically install the support ring into the bladder skin. However, there are currently a variety of assembly structures on the market, but all of them have shortcomings, such as: the existing guide head inflation introduction structure has a loud inflation leakage sound during installation, the support ring installation position is not accurate, the support ring is easy to tilt, the bladder skin cannot smoothly pass over the support ring thickness, or the support ring is on the end face of the bladder skin, resulting in the failure of the support ring to enter the bladder skin, etc.

[0003] In summary, how to provide a device that can automatically install a support ring into a bladder skin, and the assembly quality and success rate of the device are high, is a problem that needs to be solved urgently by those skilled in the art. Summary of the invention

[0019] In one embodiment, the first push rod actuating cylinder is disposed on the top of the cylinder mounting plate, and the second push rod actuating cylinder is disposed on the bottom of the cylinder mounting plate;

[0020] The cylinder mounting plate is connected to the centering plate, the centering plate is connected to the active plate, and the active plate moves up and down along the main door-shaped frame.

[0021] In one embodiment, a magnet is embedded on the end surface of the outer sleeve.

[0022] An installation method, applied to any of the above-mentioned air spring support ring installation mechanisms, comprising:

[0023] S1, the lower positioning and clamping mechanism positions and clamps the bladder skin;

[0024] S2, the support ring moves along the guide head of the upper positioning and loading mechanism to the lower end surface of the outer sleeve;

[0025] S3, the second driving member retracts downward, driving the second push rod to descend, so as to push out the multiple guide members horizontally to block the lower end surface of the support ring;

[0026] S4, the upper positioning and loading mechanism descends along the main door-shaped frame, and when the guide head contacts the bladder skin, the lower positioning and clamping mechanism fills the bladder skin with high-pressure air;

[0027] S5, the upper positioning and loading mechanism continues to descend along the main door-shaped frame, the guide head opens the bladder skin, and the bladder skin climbs upward along the guide head and the guide member until the support ring is loaded into the bladder skin, and the upper positioning and loading mechanism stops at a preset position;

[0028] S6, the first driving member extends downward, and pushes the guide member downward by a preset distance through the first push rod and the guide ring;

[0029] S7, the second driving member extends upward, driving the second push rod to rise, and the guide member retracts horizontally under the action of the return spring;

[0030] S8, the first driving member retracts upward, driving the first push rod to retract until the bottom end of the guide head retracts into the outer sleeve;

[0031] S9, the upper positioning and loading mechanism rises along the main door-shaped frame, driving the guide head and the guide member to be pulled out from the bladder skin, leaving the support ring in the bladder skin.

[0032] When using the air spring support ring installation mechanism provided by the present invention, first, place the bladder skin in the lower positioning clamping mechanism, and position and clamp the bladder skin through the lower positioning clamping mechanism. Then, move the support ring along the guide head of the upper positioning loading mechanism to the lower end surface of the outer set, and the upper end surface of the support ring is adsorbed by the lower end surface of the outer set. After that, control the second driving member to retract downward, and drive the second push rod to descend, so as to push multiple guide members horizontally outward, and the circular ring member composed of multiple guide members can block the lower end surface of the support ring. Then, control the upper positioning loading mechanism to descend along the main body door-type frame, and when the guide head contacts the bladder skin, control the lower positioning clamping mechanism to fill high-pressure air into the bladder skin. After that, control the upper positioning loading mechanism to continue to descend along the main body door-type frame, and the guide head can open the bladder skin during the descent process, and the bladder skin climbs upward along the guide head and the guide member until the support ring is loaded into the bladder skin, and the upper positioning loading mechanism stops at a preset position.

[0033] Afterwards, the first driving member is controlled to extend downward, and the guide member is pushed downward by a preset distance as a whole through the first push rod and the guide ring to avoid the guide member and the support ring from getting stuck. Subsequently, the second driving member is controlled to extend upward to drive the second push rod to rise. At this time, the guide member is horizontally retracted and reset under the action of the return spring, so that the size of the circular ring member is smaller and no longer blocks the lower end surface of the support ring. Afterwards, the first driving member is controlled to retract upward, driving the first push rod to retract until the bottom end of the guide head is retracted into the outer sleeve, and at this time, only the support ring is left on the lower end surface of the outer sleeve.

[0034] Finally, the upper positioning and loading mechanism is controlled to rise along the main body door frame, driving the guide head and the guide member to be pulled out of the bladder skin, leaving the support ring in the bladder skin. In addition, when the guide head is about to be separated from the bladder skin, the lower positioning clamping mechanism stops inflating and deflates the bladder skin to avoid the explosion sound caused by the high-pressure air when it is suddenly separated.

[0035] By using this device, the support ring can be smoothly installed, and the installation position of the support ring can be specified. During the installation process, the device can effectively reduce the leakage of high-pressure air and avoid harsh screams and blasting sounds. Since the guide head and the guide member are provided, the guide head and the guide member can be provided with an inclined surface that is convenient for them to be inserted into the bladder skin, so that the bladder skin can smoothly climb upward along the guide head and the guide member, and avoid the support ring pressing against the end surface of the bladder skin and being unable to enter the interior of the bladder skin, so as to effectively improve the assembly quality and success rate of the bladder skin and the support ring.

[0036] In summary, the air spring support ring installation mechanism provided by the present invention can automatically install the support ring into the bladder skin, and can effectively improve the assembly quality and success rate of the bladder skin and the support ring.

DETAILED DESCRIPTION

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

[0048] The core of the present invention is to provide an air spring support ring installation mechanism, which can automatically install the support ring into the bladder skin and effectively improve the assembly quality and success rate of the bladder skin and the support ring. Another core of the present invention is to provide an installation method applied to the above-mentioned air spring support ring installation mechanism.

[0049] Please refer to Figures 1 to 6 ,in, Figure 1 This is a schematic structural diagram of the air spring support ring installation mechanism provided by the present invention; Figure 2 is another structural schematic diagram of the air spring support ring mounting mechanism; Figure 3 It is a structural schematic diagram of the upper positioning loading mechanism; Figure 4 is a structural schematic diagram of the upper positioning and loading mechanism from another viewing angle; Figure 5 is a cross-sectional view of the second push rod and the guide member from a top view; Figure 6 The present invention is a flowchart of the installation method provided by the present invention.

[0050] This specific embodiment provides an air spring support ring installation mechanism, comprising:

[0051] A lower positioning and clamping mechanism 1, which is used to position the bladder skin 4 and blow air into the bladder skin 4 during the assembly process;

[0052] Main door frame 2;

[0053] The upper positioning and loading mechanism 3 is lifted and arranged in the middle of the main door-shaped frame 2. The upper positioning and loading mechanism 3 includes a guide head 301 for inserting into the bag skin 4, a guide ring 303, a first push rod 304, an outer sleeve 305 for adsorbing the support ring 5, a second push rod 306 embedded in the first push rod 304, a plurality of guide members that are spaced and matched to form a circular ring, a first driving member for driving the first push rod 304 to move up and down, and a second driving member for driving the second push rod 306 to move up and down;

[0054] The guide head 301 is connected to the guide ring 303 through the connecting rod 302 to form a guide cavity. Each guide member is arranged in the guide cavity through a reset spring. The contact surface between the guide member and the second push rod 306 is a wedge-shaped surface, so that when the second push rod 306 descends, the guide member is pushed to extend horizontally relative to the guide cavity. When the second push rod 306 rises, the reset spring pushes the guide member to retract horizontally relative to the guide cavity. The bottom of the first push rod 304 is connected to the guide ring 303 to drive the guide ring 303 to rise and fall along the inner wall of the outer sleeve 305.

[0055] It should be noted that the fixed part of the first driving member and the fixed part of the second driving member can be connected to the cylinder mounting plate 319, and the cylinder mounting plate 319 is used for lifting and moving relative to the main door frame 2. The outer sleeve 305 is arranged below the outer sleeve mounting plate 314, and the outer sleeve mounting plate 314 is arranged below the fixed part of the second driving member. The second push rod 306 is embedded in the first push rod 304, and the first push rod 304 passes through the inner wall of the outer sleeve 305 and is connected to the guide ring 303. The second push rod 306 passes through the inner wall of the first push rod 304 and contacts the guide member in the guide cavity. The driving part of the first driving member is connected to the first push rod 304 to drive the guide ring 303 to move up and down along the inner wall of the outer sleeve 305. The driving part of the second driving member is connected to the second push rod 306 to drive the second push rod 306 to move up and down. When the second push rod 306 descends, it can drive the guide member to extend outward horizontally. When the second push rod 306 moves up, the guide member retracts inward horizontally under the action of the reset spring.

[0056] In addition, it should be noted that although the lower positioning clamping mechanism 1 and the main door-type frame 2 are necessary mechanisms for the overall structure to complete its functions, they are conventional mechanisms, that is, the lower positioning clamping mechanism 1 is similar to the clamping mechanism used in the prior art for positioning the bag skin 4 and inflating the bag skin 4, and the main door-type frame 2 is also similar to the structure in the prior art for realizing the lifting and lowering movement of the upper positioning loading mechanism 3, so they will not be described in detail in this patent.

[0057] It should also be noted that the guide ring 303 needs to telescopically move along the inner wall of the outer sleeve 305, so the guide ring 303 can be set to have a certain taper structure to facilitate the guide ring 303 to be introduced into the outer sleeve 305. The lower positioning clamping mechanism 1 clamps the bladder skin 4, which means that the lower positioning clamping mechanism 1 clamps the bottom of the bladder skin 4, and the top of the bladder skin 4 can be sealed by the guide head 301.

[0058] In actual use, the shape, structure, size, material, etc. of the lower positioning clamping mechanism 1, the main door frame 2, the upper positioning loading mechanism 3, the guide head 301, the guide ring 303, the first push rod 304, the outer kit 305, the second push rod 306, the guide member, the first driving member and the second driving member can be determined according to actual conditions and actual needs.

[0059] When using the air spring support ring installation mechanism provided by the present invention, first, place the bladder skin 4 into the lower positioning and clamping mechanism 1, and position and clamp the bladder skin 4 through the lower positioning and clamping mechanism 1. Then, move the support ring 5 along the guide head 301 of the upper positioning and loading mechanism 3 to the lower end surface of the outer sleeve 305, and the upper end surface of the support ring 5 is adsorbed by the lower end surface of the outer sleeve 305. After that, control the second driving member to retract downward, and drive the second push rod 306 to descend, so as to push the multiple guide members outward horizontally, and the circular ring member composed of the multiple guide members can block the lower end surface of the support ring 5. Then, control the upper positioning and loading mechanism 3 to descend along the main door frame 2, and when the guide head 301 contacts the bladder skin 4, control the lower positioning and clamping mechanism 1 to fill the bladder skin 4 with high-pressure air. Afterwards, the upper positioning and loading mechanism 3 is controlled to continue to descend along the main door frame 2. The guide head 301 can open the bag skin 4 during the descent process. The bag skin 4 climbs upward along the guide head 301 and the guide until the support ring 5 is loaded into the bag skin 4, and the upper positioning and loading mechanism 3 stops at the preset position.

[0060] Afterwards, the first driving member is controlled to extend downward, and the guide member is pushed downward by a preset distance through the first push rod 304 and the guide ring 303 to avoid the guide member and the support ring 5 from getting stuck. Subsequently, the second driving member is controlled to extend upward to drive the second push rod 306 to rise. At this time, the guide member is horizontally retracted and reset under the action of the return spring, so that the size of the circular ring member is smaller and no longer blocks the lower end surface of the support ring 5. Afterwards, the first driving member is controlled to retract upward, driving the first push rod 304 to retract until the bottom end of the guide head 301 is retracted into the outer sleeve 305, and at this time, only the support ring is left on the lower end surface of the outer sleeve 305.

[0061] Finally, the upper positioning and loading mechanism 3 is controlled to rise along the main door-shaped frame 2, driving the guide head 301 and the guide member to be pulled out from the bladder skin 4, leaving the support ring 5 in the bladder skin 4. In addition, when the guide head 301 is about to be separated from the bladder skin 4, the lower positioning and clamping mechanism 1 can stop inflating and deflation of the bladder skin 4 to avoid the explosion sound caused by the high-pressure air when it is suddenly separated. In the process of loading the support ring 5 into the bladder skin 4, the whole structure operates stably, the feeding height of the support ring 5 can be adjusted, and the expansion of the bladder skin 4 is within the allowable range, which can ensure the assembly quality and yield rate of the product.

[0062] By using this device, the support ring 5 can be smoothly installed, and the installation position of the support ring 5 can be specified. During the installation process, the device can effectively reduce the leakage of high-pressure air and avoid the occurrence of harsh screams and blasting sounds. Since the guide head 301 and the guide member are provided, the guide head 301 and the guide member can be provided with an inclined surface that is convenient for them to be inserted into the bladder skin 4, so that the bladder skin 4 can smoothly climb upward along the guide head 301 and the guide member, and avoid the support ring 5 hitting the end surface of the bladder skin 4 and being unable to enter the bladder skin 4, so as to effectively improve the assembly quality and success rate of the bladder skin 4 and the support ring 5.

[0063] In summary, the air spring support ring installation mechanism provided by the present invention can automatically install the support ring 5 into the bladder skin 4, and can effectively improve the assembly quality and success rate of the bladder skin 4 and the support ring 5.

[0064] In one embodiment, the guide member includes a first guide block 307 and a second guide block 311 alternately spaced with the first guide block 307 , the second guide block 311 cooperates with the first guide block 307 to form a circular ring member, and the cross section of the first guide block 307 is larger than the cross section of the second guide block 311 .

[0065] It should be noted that the guide head 301 is connected to the guide ring 303 above the guide head 301 through the connecting rod 302 to form a guide cavity, and the first guide block 307 with a wider cross section and the second guide block 311 with a narrower cross section can be horizontally extended and retracted in the guide cavity. Figure 5 As shown, four first guide blocks 307 and four second guide blocks 311 are arranged alternately to form a circular ring, and the inner and outer peripheral walls of the circular ring are both circular. A gap is left between the first guide block 307 and the second guide block 311 to facilitate pushing the first guide block 307 and the second guide block 311. Moreover, a waist-shaped hole can be arranged on the first guide block 307, and the connecting rod 302 passes through the waist-shaped hole to connect the guide head 301 and the guide ring 303, and the waist-shaped hole can limit the moving range of the first guide block 307.

[0066] Of course, the first guide block 307 and the second guide block 311 can also be set to structures of other shapes and numbers, but it is necessary to ensure that the first guide block 307 and the second guide block 311 can cooperate to open or retract to form circular rings of different diameters to resist the bottom of the support ring or pass through the support ring.

[0067] It should also be noted that, in the initial state, the diameter of the circular ring is the smallest, so that the support ring 5 can be inserted into the lower end surface of the outer sleeve 305 along the outer circumference of the circular ring, and when the first guide block 307 and the second guide block 311 extend horizontally outward under the action of the second push rod 306, a circular ring structure with a larger diameter can be formed, which needs to abut against the lower end surface of the support ring 5 to prevent the support ring 5 from falling. The structural dimensions of the first guide block 307 and the second guide block 311 can be set according to the structural dimensions of the support ring 5.

[0068] In one embodiment, the return spring includes a first upper return spring 309, a first lower return spring 308, a second upper return spring 313 and a second lower return spring 312. The first upper return spring 309 is horizontally arranged between the top of the first guide block 307 (i.e., the top side) and the guide ring 303, and the first lower return spring 308 is horizontally arranged between the bottom of the first guide block 307 (i.e., the bottom side) and the guide head 301; the second upper return spring 313 is horizontally arranged between the top of the second guide block 311 and the guide ring 303, and the second lower return spring 312 is horizontally arranged between the bottom of the second guide block 311 and the guide head 301.

[0069] Therefore, when the second push rod 306 no longer pushes downward to extend the first guide block 307 and the second guide block 311 horizontally outward (or when the second push rod 306 is pushed upward), the first guide block 307 can be horizontally retracted inward under the action of the first upper return spring 309 and the first lower return spring 308, and the second guide block 311 can be horizontally retracted inward under the action of the second upper return spring 313 and the second lower return spring 312 to avoid the first guide block 307 and the second guide block 311 continuing to resist the lower end surface of the support ring 5.

[0070] In one embodiment, if Figure 5 As shown, a wedge angle and a wedge push block 310 are provided at the end of the second push rod 306, the wedge angle (which is located at the end of the second push rod 306 where the wedge push block 310 is not provided) and the first guide block 307 are provided in cooperation to push the first guide block 307 to extend horizontally, and the wedge push block 310 and the second guide block 311 are provided in cooperation to push the second guide block 311 to extend horizontally. That is, the wedge angle and the wedge push block 310 can convert the vertical movement of the second push rod 306 into the horizontal movement of the first guide block 307 and the second guide block 311.

[0071] In one embodiment, the bottom slope of the wedge-shaped corner is higher than the bottom slope of the wedge-shaped push block 310 .

[0072] It should be noted that the height positions of the wedges of the second push rod 306 and the bottom end of the wedge-shaped push block 310 (the bottom end here is also the front end that first contacts the bag skin 4) are different, so the order of the horizontal movement of the first guide block 307 and the second guide block 311 is different. In this way, when retracting, the second guide block 311 retracts first and the first guide block 307 retracts later, and the outer diameter of the circular ring part is retracted to be smaller than the inner diameter of the support ring 5, so as to facilitate the loading of the support ring 5.

[0073] Furthermore, since the bottom end slope of the second push rod 306 is higher than the bottom end slope of the wedge-shaped push block 310, during the downward movement of the second push rod 306, the second push rod 306 first contacts the first guide block 307 (whose cross section is wider), and the wedge-shaped push block 310 then contacts the second guide block 311 (whose cross section is narrower), so that when the guide member is extended, the first guide block 307 is extended first, and the second guide block 311 is extended later, forming a complete circular ring member, which can not only block the lower end surface of the support ring 5, but also form a complete guide angle to facilitate the circular ring member to enter the bladder skin 4, and can also form a closed and complete circular ring member to avoid air leakage during the process of the circular ring member entering the bladder skin 4; when the second push rod 306 moves upward and the guide member retracts, the second guide block 311 retracts first under the action of the reset spring, and when there is enough space, the first guide block 307 retracts later.

[0074] In one embodiment, the first driving member includes a first push rod actuating cylinder 318 and a first push rod mounting plate 317, the first push rod 304 is connected to the guide ring 303, the first push rod 304 is connected to the first push rod mounting 317, and the first push rod mounting plate 317 is connected to the telescopic rod of the first push rod actuating cylinder 318, so that the first push rod actuating cylinder 318 can drive the first push rod 304 to move up and down.

[0077] In one embodiment, a magnet is embedded on the end surface of the outer sleeve 305 , and the magnet can effectively absorb the support ring 5 to achieve the positioning operation of the support ring 5 .

[0078] In addition to the above-mentioned air spring support ring installation mechanism, the present invention also provides an installation method for the air spring support ring installation mechanism described in any one of the above-mentioned items, the installation method comprising:

[0079] S1, the lower positioning and clamping mechanism 1 positions and clamps the bladder skin 4;

[0080] S2, the support ring 5 moves along the guide head 301 of the upper positioning and loading mechanism 3 to the lower end surface of the outer sleeve 305;

[0081] S3, the second driving member retracts downward, driving the second push rod 306 to descend, so as to push out the multiple guide members horizontally to block the lower end surface of the support ring 5;

[0082] S4, the upper positioning and loading mechanism 3 descends along the main door-shaped frame 2, and when the guide head 301 contacts the bladder skin 4, the lower positioning and clamping mechanism 1 fills the bladder skin 4 with high-pressure air;

[0083] S5, the upper positioning and loading mechanism 3 continues to descend along the main door-shaped frame 2, the guide head 301 opens the bag skin 4, and the bag skin 4 climbs upward along the guide head 301 and the guide member until the support ring 5 is loaded into the bag skin 4, and the upper positioning and loading mechanism 3 stops at the preset position;

[0084] S6, the first driving member extends downward, and pushes the guide member downward by a preset distance through the first push rod 304 and the guide ring 303;

[0085] S7, the second driving member extends upward, driving the second push rod 306 to rise, and the guide member retracts horizontally under the action of the return spring;

[0086] S8, the first driving member retracts upward, driving the first push rod 304 to retract until the bottom end of the guide head 301 is retracted into the outer sleeve 305;

[0087] S9, the upper positioning and loading mechanism 3 rises along the main door-shaped frame 2, driving the guide head 301 and the guide member to be pulled out from the bladder skin 4, leaving the support ring 5 in the bladder skin 4.

[0088] In order to further illustrate the installation method for the air spring support ring installation mechanism provided by the present invention, an example is given below.

[0089] First, the lower positioning clamping mechanism 1 clamps the bladder skin 4, and the support ring 5 moves to the lower end surface of the outer sleeve 305 along the guide head 301 of the upper positioning loading mechanism 3. Then, the second push rod actuating cylinder 315 retracts downward, driving the second push rod 306 and the wedge-shaped push block 310 to descend, pushing the first guide block 307 and the second guide block 311 horizontally to block the lower end surface of the support ring 5. After that, the upper positioning loading mechanism 3 descends along the main door frame 2. When the guide head 301 contacts the bladder skin 4, the lower positioning clamping mechanism 1 fills the bladder skin 4 with high-pressure air, and the upper positioning loading mechanism 3 continues to descend. The guide head 301 expands the bladder skin 4, and the bladder skin 4 climbs upward along the guide head 301, the first guide block 307 and the second guide block 311 until the support ring 5 is loaded into the bladder skin 4, and the upper positioning loading mechanism 3 stops at the set position.

[0090] When the bladder skin 4 is moved to the right position, the first push rod actuating cylinder 318 extends downward, and pushes the first guide block 307, the second guide block 311, and the guide head 301 downward by a preset distance through the first push rod mounting plate 317, the first push rod 304, and the guide ring 303, so as to prevent the first guide block 307, the second guide block 311, and the support ring 5 from getting stuck. Then, the second push rod actuating cylinder 315 extends upward, driving the second push rod 306 and the wedge-shaped push block 310 to rise. During this process, the first guide block 307 and the second guide block 311 will be horizontally retracted under the action of the return spring, so that the first guide block 307 and the second guide block 311 will not block the support ring 5.

[0091] After that, the first push rod actuating cylinder 318 is controlled to retract upward, driving the first push rod 304 to retract until the bottom end of the guide head 301 is retracted into the outer sleeve 305, at which time only the supporting ring 5 is left on the lower end surface of the outer sleeve 305. Finally, the upper positioning loading mechanism 3 is controlled to rise along the main door frame 2, and the guide head 301, the first guide block 307 and the second guide block 311 are pulled out of the bladder skin 4, leaving the supporting ring 5 in the bladder skin 4. When the guide head 301 is about to be separated from the bladder skin 4, the lower positioning clamping mechanism 1 stops inflating and deflates the bladder skin 4 to avoid the explosion sound caused by the high-pressure air when it is suddenly separated.

[0092] By using this installation method on the present device, the support ring 5 can be smoothly installed, and the installation position of the support ring 5 can be specified. During the installation process, the leakage of high-pressure air is small, and harsh screams and blasting sounds can be avoided. In addition, in order to better install the support ring 5 into the bladder skin 4, an outer bevel can be set on the outer peripheral wall of the first guide block 307 and the second guide block 311, so that the bladder skin 4 can smoothly transition from the small outer diameter of the guide head 301 to the large outer diameter of the support ring 5, so as to avoid the support ring 5 hitting the end face of the bladder skin 4 and being unable to enter the bladder skin 4. That is, the bladder skin 4 needs to be gradually expanded by multiple guides, and then expanded to the same size as the support ring 5, so as to insert the support ring 5 into the bladder skin 4.

[0093] It should be noted that the first push rod 304 and the second push rod 306, the first driving member and the second driving member, the first guide block 307 and the second guide block 311, the first upper return spring 309 and the second upper return spring 313, the first lower return spring 308 and the second lower return spring 312, the first push rod actuating cylinder 318 and the second push rod actuating cylinder 315, the first push rod mounting plate 317 and the second push rod mounting plate 316 mentioned in the present application document, wherein the first and the second are only for distinguishing the different positions, and there is no order of precedence.
