Description

Technical Field

[0001] The present disclosure relates to the technical field of shock absorber assembly, and particularly relates to a shock absorber leak detection and oil injection device. Background Art

[0002] Shock absorbers are widely used in automobiles, motorcycles, etc. To accelerate the attenuation of the vibration of the vehicle frame and body and improve the ride comfort of the vehicle. When passing through an uneven road surface, although the shock-absorbing spring can filter the road vibration, the spring itself will still have reciprocating motion, and the shock absorber is used to suppress this spring jump. The shock absorption system is composed of a spring and a shock absorber. The shock absorber is not used to support the weight of the vehicle body, but to suppress the shock when the spring rebounds after absorbing shock and absorb the energy of road impact. During the production process of the shock absorber, it is necessary to check the sealing performance of the shock absorber and press-fit and inflate the airbag.

[0055] The second positioning assembly 70 includes a second supporting member 701 and a positioning member 702. The second supporting member 701 and the positioning member 702 are arranged oppositely. A second supporting portion adapted to the outer periphery of the shock absorber is formed on the second supporting member 701, and a positioning portion is formed on the positioning member 702 corresponding to the second supporting portion.

[0056] Specifically, one airbag pressing and inflating station is located in the middle of the frame 10, and two leak detection and oil injection stations are located on both sides of the airbag pressing and inflating station. One side of the leak detection and oil injection head 201 is communicated with the vacuum pumping device, and the other side is communicated with the oil storage tank. The opening and closing of the leak detection and oil injection head 201 and the vacuum pumping device are switched through a switching valve. At the same time, the opening and closing of the leak detection and oil injection head 201 and the oil storage tank are realized through the switching valve (not shown in the figure).

[0057] The first lifting mechanism 202 includes a first driving member and a first lifting block. The first lifting block is movably connected to the frame 10. Specifically, the first lifting block moves along the height direction of the frame 10, and the first lifting block is connected to the leak detection and oil injection head 201 for driving the leak detection and oil injection head 201 to lift.

[0058] The first support assembly 30 is used to connect the first positioning assembly 40, and the first positioning assembly 40 is used to provide support for the shock absorber to be tested or refueled.

[0059] The first support base 301 can be fixedly connected to the frame 10, detachably connected to the frame 10, or slidably connected to the frame 10. The above several connection methods can be set according to actual needs.

[0060] A first connecting plate is formed on the first support base 301 along the moving direction of the first lifting mechanism 202. That is, the first support base 301 is a stainless steel plate in the shape of an "L". The bottom of the first support base 301 is connected to the frame 10, the side surface of the first support base 301 is parallel to the side surface of the frame 10, and a plurality of mounting holes are formed on the side surface of the first support base 301 for connecting with the first positioning assembly 40.

[0061] Specifically, the first positioning component 40 includes a first support member 401 and a positioning rod 402. The first support member 401 is detachably connected to the first connecting plate. A first support portion adapted to the outer periphery of the shock absorber is formed on the first support member 401. Exemplarily, the first support portion is a curved groove adapted to the outer periphery of the shock absorber. At the same time, the first support member 401 can rotate relative to the first connecting plate. The specific operation is as follows: The first support member 401 and the first connecting plate are locked to a mounting hole on the side of the first connecting plate through a screw and a nut. If the angle of the first support portion needs to be adjusted, loosen the nut and then rotate the first support member 401 to the required angle and tighten the nut to complete the adjustment.

[0062] The positioning rod 402 is detachably connected to the first connecting plate, and the positioning rod 402 extends along a direction perpendicular to the moving direction of the first lifting mechanism 202. Specifically, the extending direction of the positioning rod 402 is perpendicular to the first connecting plate.

[0063] There is usually an annular structure at the end or middle of the shock absorber. The rod shape of the positioning rod 402 is adapted to the annular structure of the shock absorber. When performing leak detection or oil injection, the annular structure of the shock absorber to be tested or filled with oil is sleeved on the positioning rod 402 to fix the approximate position of the shock absorber, and then the angle of the first support member 401 is adjusted so that the first support portion fits the outer periphery of the shock absorber, and the positioning of the shock absorber can be completed. Figure 1 Both the left and right positions are leak detection and oil injection stations, respectively corresponding to the cases of leak detection of two types of shock absorbers. As Figure 1 shown, the shock absorber clamped at the left leak detection and oil injection station is a type of shock absorber, which is called the first shock absorber a in this application. The shock absorber clamped at the middle airbag press-fitting and inflation station is another type of shock absorber, which is called the second shock absorber b in this application.

[0064] Through the setting of the first positioning component 40, it can adapt to various types of shock absorbers, and at the same time use the annular structure on the shock absorber for positioning, which is more accurate than direct visual inspection by workers.

[0065] The airbag press-fitting and inflation component 50 includes an airbag press-fitting and inflation head 501, an air storage tank, and a second lifting component. The airbag press-fitting and inflation head 501 is communicated with the air storage tank.

[0068] The second support base 601 can be fixedly connected to the frame 10, detachably connected to the frame 10, or slidably connected to the frame 10. The above several connection methods can be set according to actual needs;

[0069] The second support base 601 is formed with a second connecting plate along the movement direction of the second lifting mechanism 502. That is, the second support base 601 is a stainless steel plate in the shape of an "L". The bottom of the second support base 601 is connected to the frame 10. The side surface of the second support base 601 can be parallel to the back surface of the frame 10 or parallel to the side surface of the frame 10. A plurality of mounting holes are formed on the side surface of the second support base 601 for connecting to the second positioning component 70;

[0070] Specifically, the second positioning component 70 includes a second supporting member 701 and a positioning member 702. The second supporting member 701 and the positioning member 702 are arranged oppositely. The second supporting member 701 is detachably connected to the second connecting plate. A second supporting portion adapted to the outer periphery of the shock absorber is formed on the second supporting member 701. Exemplarily, the second supporting portion is a curved groove adapted to the outer periphery of the shock absorber. At the same time, the second supporting member 701 can rotate relative to the second connecting plate. The specific operation is as follows: The second supporting member 701 and the second connecting plate are locked to a mounting hole on the side surface of the second connecting plate through a screw and a nut. If the angle of the second supporting portion needs to be adjusted, loosen the nut and then rotate the second supporting member 701 to the required angle and tighten the nut to complete the adjustment;

Preferably, it is adapted to the end portion of the shock absorber for fixing the shock absorber at the positioning portion;

[0072] Further, as Figure 3 shown, in order to facilitate adjustment and adapt to different types of shock absorbers, the shock absorber leak detection and oil injection device described in the present disclosure further includes a first sliding mechanism 80. Define the movement direction of the first lifting mechanism 202 as the z-axis direction and the extending direction of the positioning rod 402 as the x-axis direction. The first sliding mechanism 80 includes a first sliding bottom plate 801 and a first adjusting slide plate 802;

[0073] The first sliding bottom plate 801 is slidably arranged on the frame 10 along the x-axis direction;

[0074] The first adjusting slide plate 802 is slidably arranged on the first sliding bottom plate 801 along a direction perpendicular to the x-axis in the plane where the first sliding bottom plate 801 is located;

[0075] The first support assembly 30 is connected to the first adjustment slide plate 802.

[0076] Specifically, in the plane of the first sliding bottom plate 801, the direction perpendicular to the x-axis is the y-axis direction. A first screw rod arranged along the x-axis direction is provided between the frame 10 and the first sliding bottom plate 801. The first sliding bottom plate 801 is in threaded connection with the first screw rod. The first screw rod is rotated by a first handwheel fixedly connected to one end of the first screw rod, so that the first sliding bottom plate 801 moves along the axial direction of the first screw rod on the first screw rod, that is, the first sliding bottom plate 801 moves along the x-axis direction; a second screw rod arranged along the y-axis direction is provided between the first sliding bottom plate 801 and the first adjustment slide plate 802, so that the first adjustment slide plate 802 can stably move along the y-axis direction. The first adjustment slide plate 802 rotates the second screw rod through a second handwheel fixedly connected to one end of the second screw rod, and then drives the first support assembly 30 to slide along the y-axis; before fixing the shock absorber, the first handwheel can be rotated to finely adjust the first adjustment slide plate 802 and the first support assembly 30 along the x-axis direction, and then the second handwheel is rotated to finely adjust the support seat along the y-axis direction, and then the support seat is moved to a suitable position to adapt to different types of shock absorbers and support different types of shock absorbers.

[0077] Further, as Figure 4 shown, in order to facilitate adjustment and be adaptable to different types of shock absorbers, the shock absorber leak detection and oil injection device described in the present disclosure further includes a second sliding mechanism 90. Define the movement direction of the second lifting mechanism 502 as the z-axis direction and the orientation of the positioning portion as the y-axis direction. The second sliding mechanism 90 includes a second sliding bottom plate 901 and a second adjustment slide plate 902;

[0078] The second sliding bottom plate 901 is slidably arranged on the frame 10 along the direction perpendicular to the y-axis in the plane of the positioning portion;

[0079] The second adjustment slide plate 902 is slidably arranged on the second sliding bottom plate 901 along the y-axis direction;

[0080] The second support assembly 60 is connected to the second adjustment slide plate 902.

[0081] Specifically, the direction perpendicular to the x-axis within the plane where the second sliding base plate 901 is located is the y-axis direction. A third screw rod arranged along the x-axis direction is provided between the frame 10 and the second sliding base plate 901. The second sliding base plate 901 is threadedly connected to the third screw rod. The third screw rod is rotated by a third handwheel fixedly connected to one end of the third screw rod, so that the second sliding base plate 901 moves along the axial direction of the third screw rod on the second screw rod, that is, the second sliding base plate 901 moves along the x-axis direction. A fourth screw rod arranged along the y-axis direction is provided between the second sliding base plate 901 and the second adjusting slide plate 902, so that the second adjusting slide plate 902 can stably move along the y-axis direction. The second adjusting slide plate 902 rotates the fourth screw rod through a fourth handwheel (not shown in the figure) fixedly connected to one end of the fourth screw rod, and then drives the second support assembly 60 to slide along the y-axis. Before fixing the shock absorber, the third handwheel can be rotated to finely adjust the second adjusting slide plate 902 and the second support assembly 60 along the x-axis direction, and then the fourth handwheel is rotated to finely adjust the support seat along the y-axis direction, so as to move the support seat to a suitable position to adapt to different types of shock absorbers and support different types of shock absorbers.

[0082] Further, it further includes a controller, and the controller is respectively in signal connection with the first driving member and the second driving member.

[0083] Specifically, the controller can be a commonly used industrial controller such as a PLC (Programmable Logic Controller) or an MCU (Microcontroller Unit). In this embodiment, it is used for simple start-stop control. The controller is respectively in signal connection with the first driving member and the second driving member, and is used to control the start and stop of each driving member according to the production steps. In other preferred embodiments, a display screen and control buttons can also be installed on the frame 10, and the display screen and control buttons are respectively in signal connection with the controller, so as to facilitate the operator to input control instructions and observe the operation status of the equipment.

[0084] Further, the switching valve is a three-way valve, and the three-way valve is in signal connection with the controller.

[0085] Specifically, the three channels of the three-way valve are respectively communicated with the leak detection and oil injection head 201, the vacuum pumping device and the oil storage tank. There is a valve core at the connection of the three-way valve with the leak detection and oil injection head 201, the vacuum pumping device and the oil storage tank. The opening and closing of the valve core are controlled by the controller. By controlling the opening and closing of the valve core by the controller, the connection state between the leak detection and oil injection head 201 and the vacuum pumping device and the oil storage tank is further controlled.

[0086] Exemplarily, if a leak detection test is to be performed, the controller controls the valve core at the connection between the three-way valve and the storage oil tank to close, and controls the valve core at the connection between the three-way valve and the vacuum pumping device to open and the valve core at the connection between the three-way valve and the leak detection oil injection head 201 to open, and controls the vacuum pumping device to evacuate air to realize the leak detection test;

[0087] Similarly, if an oil injection operation is to be performed, the controller controls the valve core at the connection between the three-way valve and the storage oil tank to open and the valve core at the connection between the three-way valve and the leak detection oil injection head 201 to open, and controls the valve core at the connection between the three-way valve and the vacuum pumping device to close, and controls the storage oil tank to output oil to realize the oil injection operation

[0088] Furthermore, it also includes a start switch 110 and a warning light 100, and both the start switch 110 and the warning light 100 are signal-connected to the controller.

[0089] Specifically, the start switch 110 is arranged on one side of the frame 10 close to the operator, and the warning light 100 is arranged on the top of the frame 10. When the operator presses the start switch 110, a start signal is input to the device, and the controller controls each driving part to act to complete the pressing process. The controller is signal-connected to the warning light 100 and is used to output an alarm signal when the device reports an error or fails, so that the warning light 100 lights up to prompt the operator.

[0090] Furthermore, a storage cabinet and a door body are arranged at the bottom of the frame 10. An opening is provided on one side of the storage cabinet, and the door body is rotatably arranged at the opening of the storage cabinet; the vacuum pumping device, the storage oil tank and the gas storage tank are all arranged in the storage cabinet.

[0091] Specifically, a storage cabinet is provided at the bottom of the frame 10, and the inside of the cabinet body is used to accommodate the vacuum pumping device, the storage oil tank and the gas storage tank. In order to prevent the vacuum pumping device, the storage oil tank and the gas storage tank from accumulating dust, a door body is rotatably arranged at the opening of the cabinet body, which can prevent the vacuum pumping device, the storage oil tank and the gas storage tank from accumulating dust and is convenient for the staff to repair at the same time.

[0092] Furthermore, both the first driving part and the second driving part are linear cylinders, which are used to drive the corresponding executing parts to do linear reciprocating motion. The above-mentioned driving parts have the advantages of simple application, easy installation and stable driving.
