Description

Technical Field

[0001] The invention relates to the technical field of air compressor anti-impact performance detection devices, and in particular to an automobile air compressor anti-impact performance detection device and a detection method thereof. Background Art

[0002] When testing the impact resistance of automobile air compressors, it is necessary to test the air compressor legs to test the damage to the legs when the car stops when braking. In order to simulate the braking situation of the car, it is necessary to test high-speed braking and low-speed braking, and when conducting the braking test, emergency braking and slow braking should also be considered. According to the user's driving habits, when braking, emergency braking is generally used for high-speed braking, and slow braking is used for low-speed braking. Therefore, it is necessary to set up a device to test these two situations separately to analyze the impact resistance of the air compressor legs. Summary of the invention

[0003] In view of the above-mentioned technical deficiencies, the purpose of the present invention is to provide a device and method for detecting the impact resistance of an automobile air compressor, and to set up a device for separately detecting the two situations of high-speed braking and low-speed braking, so as to analyze the impact resistance of the air compressor legs.

[0004] In order to solve the above technical problems, the present invention adopts the following technical scheme: the present invention provides an anti-impact performance detection device for an automobile air compressor, comprising an elastic clamping mechanism, an air compressor mounting seat, an air compressor guide rail, a speed regulating pulling mechanism, a brake pad and a brake strip. The air compressor mounting seat can be horizontally slidably installed on the air compressor guide rail. The speed regulating pulling mechanism is used to drive the air compressor mounting seat to slide horizontally along the air compressor guide rail. The elastic clamping mechanism is located at the end of the air compressor guide rail. A brake strip is arranged on the elastic clamping mechanism. The air compressor mounting seat is provided with a brake pad for the brake strip to clamp and rub. The air compressor guide rail is installed on the air compressor mounting seat.

[0005] Preferably, the elastic clamping mechanism includes a sliding seat, a mounting clamp, a horizontal push plate, an inner pulling mechanism, a first resistance spring and two first sliding columns. The two first sliding columns can be horizontally slidably installed on the first sliding columns. The mounting clamp is fixedly installed on one end of the two first sliding columns. The brake strip is fixedly installed on the mounting clamp. The horizontal push plate is slidably installed on the two first sliding columns. The first resistance spring is used to provide elastic force between the horizontal push plate and the mounting clamp. The inner pulling mechanism is transmission-connected to the horizontal push plate, and the inner pulling mechanism pulls the horizontal push plate toward the guide rail of the air compressor.

[0006] Preferably, the elastic clamping mechanism further comprises a second resisting spring and a resisting plate, wherein the second resisting spring is fixedly mounted on one end of the first slide column, and the second resisting spring is used to provide an elastic force for the resisting plate to move away from the slide seat.

[0007] Preferably, it also includes an inner push mechanism, a clamping mechanism, a swinging and rotating mechanism and a one-way clamping mechanism. The swinging and rotating mechanism is used to convert the resistance thrust of the air compressor mounting seat into a rotational force of the swinging and rotating mechanism. The swinging and rotating mechanism is provided with a resistance rod in contact with the air compressor mounting seat, and the resistance rod is detachably installed on the swinging and rotating mechanism. The clamping mechanism is transmission-connected with the swinging and rotating mechanism, and is used to convert the rotational force of the swinging and rotating mechanism into a pulling force for pulling the inner push mechanism to move. When the clamping mechanism pulls the inner push mechanism to move inward, the inner push mechanism will push the brake strip to move inward; when the resistance rod is separated from the first push plate, the brake strip will contact the brake pad, and the one-way clamping mechanism will clamp the inner push mechanism.

[0008] Preferably, the swinging and rotating mechanism includes a rotating gear, a reversing gear and a horizontally rotatable rotating shaft, the rotating shaft is detachably connected to the interference rod, the rotating gear is fixedly mounted on the rotating shaft, the horizontally rotatable reversing gear is meshed with the rotating gear, and the reversing gear is transmission-connected to the clamping mechanism.

[0009] Preferably, the clamping mechanism comprises a first hinged rod and a horizontally slidable rack, the rack is meshed with the reversing gear, one end of the first hinged rod is hinged to the rack, and the other end is hinged to the inner pushing mechanism.

[0010] Preferably, the inner push mechanism comprises a second push plate and two second sliding columns that can slide horizontally, the second push plate is fixedly mounted on one end of the two second sliding columns, and one end of the first hinged rod is hinged to the second push plate.

[0011] Preferably, the one-way clamping mechanism comprises a trapezoidal clamping block and an elastic lifting mechanism for pushing the trapezoidal clamping block upwards.

[0012] Preferably, the inner pulling mechanism includes a vertical pushing mechanism, a second hinged rod and a fixed rod, the fixed rod is fixedly installed on the bottom of the mounting clamp, one end of the second hinged rod is hinged to the fixed rod, and the other end of the second hinged rod is hinged to the output end of the vertical pushing mechanism.

[0013] A method for detecting an impact resistance performance detection device for an automobile air compressor comprises the following steps:

[0014] Step 1: The speed regulating pulling mechanism pulls the air compressor mounting base to move horizontally.

[0015] Step 2: The air compressor mounting seat moves into the detection range of the elastic clamping mechanism, and the elastic clamping mechanism drives the brake strip to the brake pad;

[0016] After the brake strip and the brake pad come into contact, the elastic clamping mechanism continues to work, thereby increasing the clamping force to simulate the slow braking process. Through repeated tests, the connection of the air compressor leg is broken. The air compressor leg is observed by scanning electron microscope to analyze its fracture mechanism.

[0017] Step 3: Install a new air compressor guide rail on the air compressor mounting seat, and install the resistance rod on the rotating shaft, increase the speed of the speed regulating pulling mechanism to pull the air compressor mounting seat, and then use the speed regulating pulling mechanism to pull the air compressor mounting seat to move horizontally;

[0018] Step 4: When the first push plate contacts the resistance rod, the first push plate will push the resistance rod to rotate, and the resistance rod will drive the reversing gear to rotate, so that the reversing gear drives the rack to move. When the rack is pulled horizontally, the rack will pull the inner push mechanism inward through the first hinged rod, so that the inner push mechanism pushes the mounting clamp to move, thereby making the brake strip clamp the brake pad, and the one-way clamping mechanism clamps and limits the second push plate, realizing the process of high-speed emergency braking. Through repeated tests, the connection of the air compressor leg is broken, and the air compressor leg is observed by scanning electron microscope to analyze its fracture mechanism.

[0019] The beneficial effect of the present invention is that by setting an elastic clamping mechanism and a speed regulating pulling mechanism, the impact resistance performance of the air compressor can be tested in a slow low-speed braking state. And after the slow low-speed braking test, the speed regulating pulling mechanism can be accelerated to pull the air compressor to achieve the impact resistance performance test in a high-speed braking state. And in the case of high speed, in order to avoid the brake pad being unable to clamp the brake strip due to excessive speed, the resistance rod is installed on the rotating shaft, so that the inner push mechanism, the clamping mechanism, the swing rotation mechanism and the one-way clamping mechanism can work, so as to ensure that braking can also be performed in high-speed mode.

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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.

[0029] Embodiment: The present invention provides an anti-impact performance testing device for an automobile air compressor, comprising an elastic clamping mechanism 1, an air compressor mounting seat 2, an air compressor guide rail 3, a speed regulating pulling mechanism 9, a brake pad 11 and a brake strip 12. The air compressor mounting seat 2 can be horizontally slidably installed on the air compressor guide rail 3. The speed regulating pulling mechanism 9 is used to drive the air compressor mounting seat 2 to slide horizontally along the air compressor guide rail 3. The speed regulating pulling mechanism 9 can pull or push the air compressor mounting seat 2 to slide horizontally on the air compressor guide rail 3. The elastic clamping mechanism 1 is located at the end of the air compressor guide rail 3. The brake strip 12 is arranged on the elastic clamping mechanism 1. The air compressor mounting seat 2 is provided with a brake pad 11 for the brake strip 12 to clamp and rub. The air compressor guide rail 3 is installed on the air compressor mounting seat 2. When the pulling force of the speed regulating pulling mechanism 9 increases, the movement speed of the air compressor mounting seat 2 will be accelerated, so that the air compressor mounting seat 2 can achieve a faster effect, and the speed regulating pulling mechanism 9 includes a pull rope 9a, a hanging basket 9b, a steering roller 9c and a hoist for pushing the hanging basket 9b upward, the steering roller 9c is used to adjust the movement direction of the pull rope 9a, one end of the pull rope 9a is connected to the hanging basket 9b, and the other end is connected to the air compressor 10 mounting seat 2, the hoist is a vertical hoist, when the hanging basket 9b moves to the highest point, the connection between the pull rope and the hanging basket 9b will be released, so that the hanging basket 9b falls by gravity, and then the pull rope 9a is pulled to move, and the pull rope 9a will be turned by the steering roller 9c, thereby pulling the air compressor mounting seat 2 to slide horizontally along the air compressor guide rail 3.

[0030] A through-beam sensor for sensing the air compressor mounting seat sliding past is arranged on the front side of the elastic clamping mechanism 1. The sensor senses the air compressor 10 passing by, so as to control the elastic clamping mechanism 1 to perform clamping work through a controller.

[0031] It is conceivable that according to the speed requirement, the weight in the hanging basket 9b can be increased to achieve the effect of changing the movement speed of the air compressor mounting base 2 to simulate the high-speed and low-speed driving of the vehicle. The specific acceleration principle is: the gravity acceleration and the height of the hanging basket 9b do not change, only the weight is changed to achieve a greater pulling force, and the greater pulling force is used to offset the friction generated by the movement of the air compressor mounting base 2 and the pull rope 9a, thereby achieving a faster speed.

[0032] When the air compressor mounting base 2 slides into the clamping range of the elastic clamping mechanism 1, the elastic clamping mechanism 1 will quickly push the brake strip 12 to clamp the brake pad 11, and after the clamping contact, the clamping of the elastic clamping mechanism 1 will continue to improve. Since the elastic clamping mechanism 1 is an elastic clamp, the friction force gradually increases, that is, the buffer braking process is simulated.

[0033] like Figure 2As shown, the elastic clamping mechanism 1 includes a slide seat 1a, a mounting clamp plate 1c, a horizontal push plate 1e, an inner pulling mechanism 1f, a first interference spring 1d and two first slide columns 1b. The two first slide columns 1b can be horizontally slidably installed on the first slide columns 1b. The mounting clamp plate 1c is fixedly installed on one end of the two first slide columns 1b. The brake strip 12 is fixedly installed on the mounting clamp plate 1c. The horizontal push plate 1e is slidably installed on the two first slide columns 1b. The first interference spring 1d is used to provide elastic force between the horizontal push plate 1e and the mounting clamp plate 1c. There are two first interference springs 1d. The two first interference springs 1d are respectively sleeved on the two first slide columns 1b. One end of the first interference spring 1d is in conflict with the horizontal push plate 1e, and the other end is in conflict with the mounting clamp plate 1c. Of course, the two ends of the first interference spring 1d can also be respectively in conflict with the horizontal push plate 1 e is fixedly connected to the mounting clamp plate 1c, so that when the horizontal push plate 1e is reset, the first resistance spring 1d can be pulled to pull the mounting clamp plate 1c, so that the mounting clamp plate 1c is also reset, and the inner pulling mechanism 1f is transmission-connected with the horizontal push plate 1e, and the inner pulling mechanism 1f pulls the horizontal push plate 1e toward the air compressor guide rail 3. When the inner pulling mechanism 1f pulls the horizontal push plate 1e inward and the horizontal push plate 1e is pushed horizontally, the horizontal push plate 1e will be driven by the first resistance spring 1d to push the brake strip 12 to slowly brake the air compressor mounting seat 2, and when the brake strip 12 contacts the brake pad 11, the inner pulling mechanism 1f will continue to push the horizontal push plate 1e, so that the first resistance spring 1d is compressed to a larger deformation amount, thereby increasing a greater thrust to simulate the slow braking process.

[0034] There can be two elastic clamping mechanisms 1, and the two elastic clamping mechanisms 1 are respectively arranged on both sides of the air compressor guide rail 3. The horizontal push plates 1e on the two elastic clamping mechanisms 1 are driven by the inner pulling mechanism 1f, so that the two brake strips 12 contact the brake pads 11 on both sides of the air compressor mounting seat 2 at the same time, that is, when the air compressor mounting seat 2 is braked, the air compressor mounting seat 2 will not be offset laterally, so as to better simulate the situation where the rear two wheels are braked at the same time when the vehicle brakes.

[0035] like Figure 2As shown, the elastic clamping mechanism 1 also includes a second resisting spring 1h and a resisting plate 1j. The second resisting spring 1h is fixedly mounted on one end of the first sliding column 1b. The second resisting spring 1h is used to provide an elastic force to the resisting plate 1j away from the sliding seat 1a. In the process of the horizontal push plate 1e pushing the first resisting spring 1d to compress, since the initial yield strength of the first resisting spring 1d is greater than the initial yield strength of the second resisting spring 1h, the second resisting spring 1h will be compressed first. In the process of compression, the elastic force gradually increases, and the yield strength increases, that is, when the yield strength of the second resisting spring 1h is greater than the yield strength of the first resisting spring 1d, the first resisting spring 1d is compressed again, so that when the horizontal push plate 1e is reset, when the first resisting spring 1d recovers its elastic deformation, the second resisting spring 1h has not recovered yet, so that the second resisting spring 1h can push the brake strip 12 to separate from the brake pad 11.

[0036] like Figure 3 and Figure 4 As shown, it is characterized in that it also includes an inner push mechanism 4, a clamping mechanism 5, a swinging and rotating mechanism 6 and a one-way clamping mechanism 7. The swinging and rotating mechanism 6 is used to convert the resistance thrust of the air compressor mounting seat 2 into the rotational force of the swinging and rotating mechanism 6. A resistance rod 6a in contact with the air compressor mounting seat 2 is provided on the swinging and rotating mechanism 6. The air compressor mounting seat 2 is provided with a first push plate 2a in contact with the resistance rod 6a. The first push plate 2a is used for horizontal sliding. When the first push plate 2a contacts the resistance rod 6a, the first push plate 2a will push the resistance rod 6a to rotate, so that the resistance rod 6a drives the swinging and rotating mechanism 6 as a whole to work through rotation. The resistance rod 6a can be detachably installed on the swinging and rotating mechanism 6 so that when high-speed emergency braking is not performed, During simulation, the interference rod 6a can be disassembled so that the swinging rotating mechanism 6 does not contact the air compressor mounting seat 2 during movement, so as to avoid driving the inner pushing mechanism 4 to push the brake strip 12 to move. The clamping mechanism 5 is connected to the swinging rotating mechanism 6 in a transmission manner, and is used to convert the rotational force of the swinging rotating mechanism 6 into a pulling force for pulling the inner pushing mechanism 4 to move. When the swinging rotating mechanism 6 rotates, the swinging rotating mechanism 6 will drive the clamping mechanism 5 to move, so that the clamping mechanism 5 pulls the inner pushing mechanism 4 inwardly. When the clamping mechanism 5 pulls the inner pushing mechanism 4 to move inwardly, the inner pushing mechanism 4 will push the brake strip 12 to move inwardly, so that when the installation clamp plate 1c is pushed, it will push the installation clamp plate 1c and then drive the brake strip 12 to move inwardly.

[0037] When the resistance rod 6a separates from the first push plate 2a, the brake strip 12 will contact the brake pad 11, so that the brake strip 12 and the brake pad 11 are in hard contact, thereby realizing the emergency braking process, and the one-way clamping mechanism 7 will clamp the inner push mechanism 4 to avoid the friction and separation between the brake strip 12 and the brake pad 11. During the movement of the brake strip 12, the inner push mechanism 4 will push the one-way clamping mechanism 7 to avoid it.

[0038] There can be two inner pushing mechanisms 4, two clamping mechanisms 5 and two one-way clamping mechanisms 7, and the swinging and rotating mechanism 6 is transmission-connected with the two clamping mechanisms 5, so that the two inner pushing mechanisms 4 can push the two brake strips 12 inward at the same time.

[0039] like Figure 5 As shown, the swinging and rotating mechanism 6 includes a rotating gear 6c, a reversing gear 6d and a rotating shaft 6b that can rotate horizontally. The rotating shaft 6b rotates horizontally through a rotating seat installed on the ground. The rotating shaft 6b is detachably connected to the interference rod 6a. The rotating shaft 6b is provided with a connecting plate that is detachably connected to the interference rod 6a. The rotating gear 6c is fixedly installed on the rotating shaft 6b. The reversing gear 6d that can rotate horizontally is meshed with the rotating gear 6c. The reversing gear 6d rotates horizontally through the rotating seat. The reversing gear 6d is transmission-connected to the clamping mechanism 5. When the first push plate 2a pushes the interference rod 6a to rotate, the interference rod 6a will drive the reversing gear 6d to rotate, so that the reversing gear 6d drives the clamping mechanism 5 to move.

[0040] like Figure 4 As shown, the clamping mechanism 5 includes a first hinged rod 5b and a rack 5a that can slide horizontally. The rack 5a is fixedly installed on the top of the rack 5a and a slide rail installed through a mounting frame. The slide seat and the slide rail are slidably connected, so that the rack 5a can slide horizontally. The rack 5a is meshed with the reversing gear 6d, so that when the rack 5a rotates, the rack 5a will push the reversing gear 6d to move horizontally through the meshing. One end of the first hinged rod 5b is hinged to the rack 5a, and the other end is hinged to the inner push mechanism 4. When the rack 5a is pulled horizontally, the rack 5a will pull the inner push mechanism 4 to move inward through the first hinged rod 5b, so that the inner push mechanism 4 pushes the mounting clamp 1c to move, and then the brake strip 12 clamps the brake pad 11.

[0041] like Figure 5 As shown, the inner push mechanism 4 includes a second push plate 4a and two second sliding columns 4b that can slide horizontally. The second sliding columns 4b can slide horizontally through a sliding seat. The second push plate 4a is fixedly installed on one end of the two second sliding columns 4b. One end of the first hinged rod 5b is hinged to the second push plate 4a. When the first hinged rod 5b is pulled, the second push plate 4a is driven to push the brake strip 12 to clamp the brake pad 11.

[0042] like Figure 5As shown, the one-way clamping mechanism 7 includes a trapezoidal clamping block 7a and an elastic lifting mechanism 7b for pushing the trapezoidal clamping block 7a upward. When the second push plate 4a is pushed horizontally, the second push plate 4a will contact the inclined surface of the trapezoidal clamping block 7a, so that the trapezoidal clamping block 7a is pushed downward. When the brake strip 12 contacts the brake pad 11, the plane side of the trapezoidal clamping block 7a will contact the second push plate 4a, realizing the clamping limit of the second push plate 4a. The elastic lifting mechanism 7b includes a resisting spring and a square guide column and a limit plate installed under the square guide column. The elastic lifting mechanism 7b is used to apply an upward elastic force to the trapezoidal clamping block 7a, and the lifting position of the trapezoidal clamping block 7a is limited by the limit plate.

[0043] like Figure 6 As shown, the inner pulling mechanism 1f includes a vertical pushing mechanism 1f1, a second hinged rod 1f2 and a fixed rod 1f3. The fixed rod 1f3 is fixedly installed at the bottom of the mounting clamp plate 1c. One end of the second hinged rod 1f2 is hinged to the fixed rod 1f3, and the other end of the second hinged rod 1f2 is hinged to the output end of the vertical pushing mechanism 1f1. The vertical pushing mechanism 1f1 includes an electric push rod and an articulated seat articulated to the second articulated rod 1f2. The articulated seat is fixedly installed on the output end of the vertical pushing mechanism 1f1. The articulated seat assists in limiting the up and down movement of the articulated seat through a guide column and a guide seat. When the output end of the electric push rod is pulled downward, the second articulated rod 1f2 will be pulled to move, so that the fixed rod 1f3 will pull the mounting clamp plate 1c to move inward.

[0044] A method for detecting an impact resistance performance detection device for an automobile air compressor comprises the following steps:

[0045] Step 1: The speed regulating pulling mechanism 9 pulls the air compressor mounting base 2 to move horizontally.

[0046] Step 2: The air compressor mounting base 2 moves into the detection range of the elastic clamping mechanism 1, and the elastic clamping mechanism 1 drives the brake strip 12 to the brake pad 11;

[0047] After the brake strip 12 contacts the brake pad 11, the elastic clamping mechanism 1 continues to work, thereby increasing the clamping force to simulate the slow braking process. Through repeated tests, the connection of the air compressor leg is broken. The air compressor leg is observed by scanning electron microscope to analyze its fracture mechanism.

[0048] Step 3: Install a new air compressor guide rail 3 on the air compressor mounting seat 2, and install the abutment rod 6a on the rotating shaft 6b, increase the speed of the speed regulating pulling mechanism 9 to pull the air compressor mounting seat 2 to move horizontally, and then use the speed regulating pulling mechanism 9 to pull the air compressor mounting seat 2;

[0049] Step 4: When the first push plate 2a contacts the resistance rod 6a, the first push plate 2a will push the resistance rod 6a to rotate, and the resistance rod 6a will drive the reversing gear 6d to rotate, so that the reversing gear 6d drives the rack 5a to move. When the rack 5a is pulled horizontally, the rack 5a will pull the inner push mechanism 4 to move inward through the first hinged rod 5b, so that the inner push mechanism 4 pushes the mounting clamp 1c to move, and then the brake strip 12 clamps the brake pad 11, and the one-way clamping mechanism 7 clamps and limits the second push plate 4a, realizing the process of high-speed emergency braking. Through repeated tests, the connection of the air compressor leg is broken, and the air compressor leg is observed by scanning electron microscope to analyze its fracture mechanism.

[0050] By setting up an elastic clamping mechanism and a speed regulating pulling mechanism, the air compressor can be tested for its impact resistance under slow braking at low speed. After the slow braking test at low speed, the speed regulating pulling mechanism can be used to accelerate the speed of the air compressor to achieve the impact resistance test under high-speed braking. In addition, in the case of high speed, in order to avoid the brake pads being unable to clamp the brake strips due to excessive speed, the resistance rod is installed on the rotating shaft so that the inner push mechanism, the clamping mechanism, the swinging rotating mechanism and the one-way clamping mechanism can work to ensure that braking can also be performed in high-speed mode.

[0051] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.

9. A detection method for the impact resistance detection device for an automobile air compressor according to claim 7, characterized in that: The following steps are involved: Step 1: The speed regulating pulling mechanism (9) pulls the air compressor mounting base (2) to move horizontally; Step 2: The air compressor mounting base (2) moves into the detection range of the elastic clamping mechanism (1), and the elastic clamping mechanism (1) drives the brake strip (12) to the brake pad (11); After the brake strip (12) contacts the brake pad (11), the elastic clamping mechanism (1) continues to work, thereby increasing the clamping force to simulate a slow braking process. Through repeated tests, the connection between the air compressor legs is broken, and the air compressor legs are observed by scanning electron microscopy to analyze their fracture mechanism. Step 3: Install a new air compressor guide rail (3) on the air compressor mounting seat (2), and install the abutment rod (6a) on the rotating shaft (6b), increase the speed at which the speed regulating pulling mechanism (9) pulls the air compressor mounting seat (2) to move, and then pulls the air compressor mounting seat (2) through the speed regulating pulling mechanism (9) to perform horizontal movement; Step 4: When the first push plate (2a) contacts the abutment rod (6a), the first push plate (2a) will push the abutment rod (6a) to rotate, and the abutment rod (6a) will drive the reversing gear (6d) to rotate, so that the reversing gear (6d) drives the rack (5a) to move. When the rack (5a) is pulled horizontally, the rack (5a) will pull the inner push mechanism (4) inward through the first hinge rod (5b), so that the inner push mechanism (4) pushes the mounting clamp (1c) to move, thereby causing the brake strip (12) to clamp the brake pad (11), and the one-way clamping mechanism (7) clamps and limits the second push plate (4a), thereby realizing the process of high-speed emergency braking. Through repeated tests, the connection of the air compressor leg is broken, and the air compressor leg is observed by scanning electron microscope to analyze its fracture mechanism.
