Description

Technical Field

[0001] The utility model belongs to the technical field of grinding and polishing the end of a shock-absorbing air bag, and particularly relates to a device for grinding and polishing the end of a shock-absorbing air bag. Background Technique

[0002] The end of the shock-absorbing air bag is a shock-absorbing accessory used on an automobile. It is installed on the suspension of the vehicle body, and pneumatic shock absorption is achieved through the shock-absorbing air bag, thereby achieving an enhanced shock-absorbing effect for the automobile.

[0003] The main structure of the shock-absorbing air bag includes an air bag end housing and a rubber air bag installed on the air bag housing. Pneumatic shock absorption is achieved by filling a certain pressure of gas into the rubber air bag.

[0004] The air bag end housing of the shock-absorbing air bag is made of plastic and is processed and produced by an injection molding method. The air bag end housing obtained after injection molding needs to undergo many processing procedures such as water boiling and toughening treatment to obtain a plastic housing workpiece. However, due to the plastic housing processed by the injection molding method, there are burrs, bulges and other defects on some housings, which seriously affect the smoothness of the plastic housing. Therefore, defective products need to be ground and polished. Specifically, because the air bag end housing of the shock-absorbing air bag has a special-shaped structure, in the prior art, the air bag end housing can only be ground and polished by an operator holding it by hand. Similarly, it is difficult to firmly hold the air bag end housing of the shock-absorbing air bag with a special-shaped structure. The high-speed rotating polishing wheel makes it impossible to stably support the housing, and it is impossible to control the polishing and grinding force well.

[0005] At the same time, during the production process, once the mold has problems, a large number of defective products produced need to be polished and ground. Obviously, the polishing and grinding efficiency is too low to polish and grind the batch of defective products. Content of the Utility Model

[0006] Based on the above background, the purpose of the utility model is to provide a device for grinding and polishing the end of a shock-absorbing air bag.

[0007] To achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A device for grinding and polishing the end of a shock-absorbing air bag, including an air bag end grinding and polishing fixture. The air bag end grinding and polishing fixture includes a grinding and polishing table, and a rotary grinding and polishing assembly is assembled and connected to the grinding and polishing table. The rotary grinding and polishing assembly includes a first fixture table and a second fixture table which are arranged at intervals on both sides;

[0009] A number of mutually cooperating elastic top support assemblies are respectively rotatably connected to the side walls of the first fixture table and the second fixture table facing each other;

[0010] The bullet top support assembly includes a rotating shaft rotatably connected to the corresponding first fixture table and second fixture table. End limit seats are installed at the ends of the rotating shaft facing each other. A number of spring pressing plates are installed on the outer side wall of the end limit seat. The spring pressing plates are slidably connected and assembled in the end limit seat through spring structures;

[0011] A number of drive motors for driving the rotation of the rotating shaft are assembled and connected to the second fixture table;

[0012] A cylinder for pushing the first fixture table to move is assembled and connected to the first fixture table;

[0013] During the grinding and polishing process, the end shell of the shock-absorbing airbag is installed on the bullet top support assembly on the second fixture table. The first fixture table is pushed close by the cylinder so that the bullet top support assembly on the first fixture table elastically presses against the inside of the shell of the shock-absorbing airbag. Under the drive of the drive motor, the shell of the airbag end rotates for polishing.

[0014] Preferably, the spring pressing plate includes a horizontally arranged pressing portion, and the pressing portion is integrally formed with an L-shaped sliding portion;

[0015] The spring structure includes a short sliding rod fixedly connected to the end limit seat. The short sliding rod is slidably connected to the lower L-shaped sliding portion;

[0016] A short spring is sleeved on the short sliding rod, and the two ends of the short spring are respectively fixedly connected to the L-shaped sliding portion and the end limit seat.

[0017] Preferably, a number of mounting holes are provided on the first fixture table and the second fixture table, and bearings are installed in the mounting holes;

[0018] The rotating shaft is fixedly assembled on the bearing.

[0019] Preferably, the second fixture table rotates through a rotating structure;

[0020] The angle of the airbag end shell positioned on the bullet top support assembly is adjusted through the rotating structure.

[0021] Preferably, the rotating structure includes bearing brackets rotatably connected to the front and rear ends of the second fixture table respectively. The bearing brackets are fixedly installed on the top of the grinding and polishing table. A rotating shaft rotatably connected to the bearing brackets is fixedly connected to the second fixture table;

[0022] The rotating structure further includes a rotating motor, and the output shaft of the rotating motor is fixedly installed on the rotating shaft.

[0023] Preferably, sliding frames are respectively fixedly connected to the front and rear ends of the first fixture table, and the bottom of the sliding frames is slidably connected to the grinding and polishing table through a spring sliding structure.

[0024] Preferably, the spring sliding structure includes a chute formed on the polishing table, and a sliding seat slidably connected to the chute is installed at the bottom of the carriage;

[0025] A slide bar slidably connecting the sliding seat is fixedly connected in the chute.

[0026] Preferably, a spring is sleeved on the slide bar, and two ends of the spring are respectively fixedly connected to the front side wall of the chute and the side wall of the sliding seat.

[0027] Preferably, a cylinder block seat is installed at the bottom of the cylinder barrel of the air cylinder, and the cylinder block seat is fixed on the polishing table;

[0028] The cylinder block seat and the cylinder barrel of the air cylinder are connected by a plurality of connecting screws.

[0029] The utility model has the following beneficial effects:

[0030] 1. During the working process, the end shell of the air bag with a special-shaped structure is locked. Specifically, the two lip openings of the end shell of the air bag are locked by the spring pressing plate structure, and the two lip openings of the shell are in an elastic contact locking state. When the driving motor is turned on, the shock-absorbing air pump shell under clamping and positioning rotates at this time, and the operator uses sandpaper or a polishing disc to touch the outer side wall of the shell to realize the deburring, grinding and polishing of the burrs and bulges on the shell. In this way, multiple accessories are locked synchronously and multiple workpieces are polished synchronously. Therefore, this method solves the technical defect that it is difficult to lock the end shell of the air bag with special-shaped processing during the polishing and grinding process. And for the shell in the locked state, during the rotation process, the polishing and grinding force can be effectively controlled (the contact pressure of the sandpaper is easy to control).

[0031] 2. During the polishing process, for the defects in the hidden parts, it is difficult to polish the horizontally rotating shell. At this time, the shell is tilted up to facilitate polishing. Specifically, after the polishing process, the first fixture table disengages from the shell with the assistance of the air cylinder. At this time, the second fixture table rotates to tilt up the shell. Since one end of the shell is still in the locked state and the driving motor still drives the shell to rotate, the tilted shell in the rotating state is more likely to expose the hidden parts, facilitating the polishing process.

[0043] Embodiment 1

[0044] As shown Figures 1-6 in the figure, a grinding and polishing device for the end of a shock-absorbing airbag includes an airbag end grinding and polishing fixture. The airbag end grinding and polishing fixture includes a grinding and polishing table 5. A rotary grinding and polishing component is assembled and connected to the grinding and polishing table 5. Specifically, the special-shaped shock-absorbing airbag end housing is firmly locked and clamped through a specific method and rotated. After the shock-absorbing airbag end housing rotates, it is efficiently ground and polished without dead ends by auxiliary grinding tools such as grinding discs or grinding sandpapers, and burrs, bulges and other defective structures on the housing are fully removed.

[0045] Specifically, the rotary grinding and polishing component includes a first fixture table 11 and a second fixture table 12 arranged at intervals on both sides. A number of mutually cooperating spring top support components 22 are rotatably connected to the mutually facing side walls of the first fixture table 11 and the second fixture table 12.

[0046] Specifically, the spring top support component 22 includes a rotating shaft 21 rotatably connected to the corresponding first fixture table 11 and second fixture table 12 (specific method: a number of mounting holes are provided on the first fixture table 11 and the second fixture table 12, and bearings 13 are installed in the mounting holes; the rotating shaft 21 is fixedly assembled on the inner ring of the bearing). End limit seats 221 are installed at the mutually facing ends of the rotating shaft 21. A number of spring pressing plates 222 are installed on the outer side wall of the end limit seat 221. The spring pressing plates 222 are slidably connected and assembled in the end limit seat through a spring structure.

[0047] Specifically, the spring pressing plate 222 includes a horizontally arranged pressing part, and the pressing part is integrally formed with an L-shaped sliding part; the spring structure includes a short sliding rod 223 fixedly connected to the end limit seat. The short sliding rod 223 is slidably connected to the L-shaped sliding part; a short spring 224 is sleeved on the short sliding rod 223, and both ends of the short spring 224 are fixedly connected to the L-shaped sliding part and the end limit seat 221 respectively (a partition cap is fixedly connected to the outer end of the short sliding rod).

[0048] At the same time, a number of drive motors 3 for driving the rotating shaft 21 to rotate are assembled and connected to the second fixture table 12 (specifically, the fixing method is the same as that of the existing motor. The motor is fixed on the side wall of the second fixture table 12, and its output shaft is fixedly installed with the rotating shaft 21). During the working process, the operator first fixes the lip of one end of the airbag end housing (the two ends of the airbag end housing have lips) through the spring top support components on the second fixture table 12. The specific method is: all the spring pressing plates 222 are pressed in a mutually approaching manner, and after being sleeved into the lip, under the restoring force of the spring, at this time, the spring pressing plates 222 abut against the inner side wall of the lip.

[0049] In order to support and fix the spring-loaded support component on the first fixture table 11 into the lip on the other side of the housing, a cylinder 2 for pushing the first fixture table 11 to move is assembled and connected to the first fixture table 11 as described above.

[0050] After pressing the spring pressure plates 222 in a manner of approaching each other in the same way as described above, the cylinder 2 is used to carry the first fixture table 11 towards the second fixture table 12 until the spring pressure plates 222 elastically abut against the lip on the other side of the housing. At this time, the lips on both sides of the housing are in an elastically abutted and locked state. The driving motor 3 is turned on, and at this time, the shock-absorbing air pump housing held and positioned rotates. The operator uses sandpaper or a polishing disc to abut against the outer side wall of the housing in the conventional grinding and polishing method disclosed in the prior art to achieve the grinding and polishing treatment of the burrs and bulges on the housing.

[0051] Embodiment 2

[0052] As Figures 1-6 shown, on the basis of the structure of Embodiment 1 in this embodiment, the sliding connection method of the first fixture table 11 is as follows:

[0053] Sliding frames 111 are respectively fixedly connected to the front and rear ends of the first fixture table 11 (connecting shafts are respectively fixedly connected to the front and rear ends of the first fixture table 11, and the connecting shafts are fixedly installed on the sliding frames 111), and the bottom of the sliding frames 111 is slidably connected to the polishing table 5 through a spring sliding structure.

[0054] Specifically, the spring sliding structure includes a chute opened on the polishing table 5, and a sliding seat 14 slidably connected in the chute is installed at the bottom of the sliding frame 111; a sliding rod 15 slidably connecting the sliding seat 14 is fixedly connected in the chute. A spring 16 is sleeved on the sliding rod 15, and both ends of the spring 16 are respectively fixedly connected to the front side wall of the chute and the side wall of the sliding seat 14.

[0055] A cylinder block seat is installed at the bottom of the cylinder barrel of the cylinder 2 (the piston rod of the cylinder 2 is fixed at the lower end position of the side wall of the first fixture table 11), and the cylinder block seat is fixed on the polishing table 5; specifically, the cylinder block seat and the cylinder barrel of the cylinder 2 are connected by a plurality of connecting screws.

[0056] During the working process, under the push of the cylinder 2, at this time, the first fixture table 11 approaches the second fixture table 12 and locks the plastic housing at the end of the air bag in the above manner.

[0057] In this process, the sliding seat 14 compresses the spring 16, and after processing, the cylinder 2 is turned off, and under the auxiliary restoring force of the spring 16, the spring-loaded support component on the first fixture table 11 quickly disengages from the lip position of the plastic housing at the end of the air bag.

[0058] Embodiment 3

[0059] AsFigures 1-6 As shown, based on the structure of Embodiment 2, the second fixture table 12 rotates through a rotating structure in this embodiment.

[0060] Specifically, the angle of the airbag end housing positioned on the elastic top support assembly is adjusted through the rotating structure.

[0061] Specifically, during the polishing process, for the defects in the hidden parts, it is difficult for the horizontally rotating housing to be polished. At this time, the housing is tilted up to facilitate polishing. Specifically, after the polishing process, the first fixture table 11 disengages from the housing with the assistance of the cylinder 2. At this time, the second fixture table 12 is rotated to tilt up the housing. Since one end of the housing is still in the locked state, the driving motor 3 still drives the housing to rotate. At this time, the tilted housing in the rotating state is more likely to expose the hidden parts, facilitating the polishing process.

[0062] Specifically, the rotating structure includes bearing brackets 121 rotatably connected to the front and rear ends of the second fixture table 12 respectively. The bearing brackets 121 are fixedly installed on the top of the polishing table 5. A rotating shaft (a rolling bearing is installed in the bearing bracket 121) rotatably connected to the bearing bracket 121 is fixedly connected to the second fixture table 12; the rotating structure further includes a rotating motor. In the conventional manner, the output shaft of the rotating motor 4 is fixedly installed on the rotating shaft. In the conventional manner, the rotating motor 4 is installed on the polishing table 5 through a motor base (not shown in the figure).

[0063] Of course, the above description is not a limitation of the present invention, and the present invention is not limited to the above examples. Changes, modifications, additions, or substitutions made by those skilled in the art within the essence of the present invention should also fall within the protection scope of the present invention.
