Description

Technical Field

[0001] The utility model relates to the technical field of flange sleeve processing, in particular to a special polishing device for the inner diameter of a flange sleeve. Background Art

[0002] Currently, if the inner diameter roughness value of the flange sleeve does not meet the standard, the inner diameter size of the flange sleeve bushing will be different after press-fitting (the inner diameter roughness will affect the peeling force after press-fitting the flange sleeve, so the roughness is one of the key controlled dimensions in this part). The current roughness standard for the inner diameter of the flange sleeve is below Ra1.60, but there will be out-of-tolerance phenomena after actual turning.

[0003] The current process of flange sleeve inner diameter polishing is as follows:

[0004] After the flange sleeve is turned, the inner diameter is polished for 5 seconds on the lathe while the flange sleeve is running at high speed and held with 600# sandpaper. This poses a great safety hazard and the degree of automation needs to be improved. In addition, the flange sleeve is currently fixed during the polishing process by the machine tool clamp, but the surface of the flange sleeve is easily worn during the clamp locking process. In summary, the polishing process of the flange sleeve needs to be further optimized. Utility Model Content

[0005] The purpose of the utility model is to solve the problems raised in the above background technology, and then proposes a special polishing device for the inner diameter of a flange sleeve.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A special polishing device for the inner diameter of a flange sleeve includes a mounting plate, a driving motor, a primary pulley, a fixing plate, a rotating roller, a secondary pulley, a belt, a rubber layer, a deflection assembly, a pressure roller, a mounting platform, a telescopic member, and a polishing assembly.

[0008] The driving motor, the fixing plate, the deflection assembly and the mounting platform are all arranged on the mounting plate;

[0009] The main pulley is connected to the drive motor;

[0010] The two rotating rollers are respectively connected to the interior of the fixed plate and are symmetrically distributed. The rotating rollers are covered with a rubber layer.

[0011] The two secondary pulleys are respectively arranged at the other ends of the two rotating rollers and are connected to the primary pulley through belts;

[0012] The pressure roller is connected to a deflection assembly;

[0013] The telescopic member is arranged on the mounting platform and the polishing assembly is connected to the telescopic member.

[0014] Furthermore, the deflection assembly includes a mounting rod, a drive box and a deflection rod.

[0015] The mounting rod is disposed on the mounting plate;

[0016] The drive box is arranged on the mounting rod and a drive assembly is arranged in the drive box;

[0017] One end of the deflection rod is connected with a driving assembly so that the deflection rod moves in a circular motion, and a pressure roller is rotatably connected to the deflection rod.

[0018] The above solution can drive the pressure roller to make circular motion through the deflection component and thus contact the upper part of the flange sleeve. At the same time, it can cooperate with the two rotating rollers to avoid position deviation of the flange sleeve during the subsequent polishing process.

[0019] Furthermore, the driving assembly is a chain drive or a gear drive.

[0020] Furthermore, the polishing assembly includes a servo motor and a polishing wheel.

[0021] The servo motor is connected with a telescopic member;

[0022] The polishing wheel is connected to a servo motor.

[0023] The above solution can realize the circumferential polishing of the inner diameter of the flange sleeve by using the telescopic part, the polishing assembly and the belt transmission method.

[0024] Furthermore, a distance sensor is provided on the fixing plate.

[0025] Furthermore, the fixing plate is also provided with a voice prompter electrically connected to the distance sensor.

[0026] The above scheme can limit the placement area of the flange sleeve on the rotating roller through the distance sensor. When the distance sensor detects that the distance range between the flange sleeve and it reaches the preset numerical range, it will immediately feedback the signal to the controller. The controller then controls the voice prompter and the drive component to work in sequence. The voice prompter can remind the placement personnel that the flange sleeve has been placed in place. The drive component can drive the deflection rod to move and then limit the upper position of the flange sleeve through the pressure roller to avoid the flange sleeve from moving up and down during the subsequent polishing process.

[0027] Furthermore, a timer is also included.

[0028] The above scheme can accurately limit the total processing time of a flange sleeve through a timer. When the preset time is reached, the polishing is immediately ended, and then a new flange sleeve can be replaced to start a new round of processing.

[0029] Compared with the prior art, the beneficial effects of the present invention are:

[0030] Compared with the existing technology, this device does not require manual labor to hold 600# sandpaper to press the high-speed rotating flange sleeve for inner diameter polishing, thereby significantly reducing the safety hazards in the polishing process, and significantly improving the degree of automation of polishing. At the same time, the probability of surface wear of the flange sleeve when fixing it is significantly reduced, and the probability of surface damage of the flange sleeve during the entire polishing process is greatly reduced, and the polishing effect is better.

[0035] 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 embodiments described 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 making creative work are within the scope of protection of the present invention. The present invention is further described in conjunction with the drawings and embodiments:

[0036] like Figure 1 and Figure 2 As shown, a special polishing device for the inner diameter of a flange sleeve includes a mounting plate 1, a drive motor 11, a primary pulley 12, a fixed plate 13, a rotating roller 14, a secondary pulley 15, a belt 16, a rubber layer 17, a deflection assembly, a pressure roller 24, a mounting platform 31, a telescopic member 32, and a polishing assembly.

[0037] The driving motor 11, the fixing plate 13, the deflection assembly and the mounting platform 31 are all arranged on the mounting plate 1;

[0038] The main pulley 12 is connected to the drive motor 11;

[0039] The two rotating rollers 14 are rotatably connected to the interior of the fixed plate 13 and are symmetrically distributed. One end of the rotating roller 14 is sleeved with a rubber layer 17 in contact with the flange sleeve 101.

[0040] Two secondary pulleys 15 are respectively provided at the other end of the rotating roller 14 and are connected to the primary pulley 12 via a belt 16; (after the belt 16 is installed on the primary pulley 12 and the secondary pulley 15, it is tightened. The tightening of the belt is a prior art and will not be described here.)

[0041] The pressure roller 24 is connected to a deflection assembly;

[0042] The telescopic member 32 is disposed on the mounting platform 31 and the polishing assembly is connected to the telescopic member 32 (specifically, the telescopic member 32 is an electric push rod or an electric cylinder).

[0043] Further refinement of the embodiment of the present invention is as follows: Figure 1 and Figure 2 As shown, the deflection assembly includes a mounting rod 21, a drive box 22 and a deflection rod 23.

[0044] The mounting rod 21 is provided on the mounting plate 1;

[0045] The drive box 22 is provided on the mounting rod 21 and a drive assembly is provided in the drive box 22 (specifically, the drive assembly is one of a chain drive or a gear drive, both of which belong to the prior art and their working principles are not described and are not shown in the figure);

[0046] One end of the deflection rod 23 is connected to a driving assembly to enable the deflection rod 23 to move in a circular motion, and a pressure roller 24 is rotatably connected to the deflection rod 23 .

[0047] Further refinement of the embodiment of the present invention is as follows: Figure 1 As shown, the polishing assembly includes a servo motor 33 and a polishing wheel 34.

[0048] The servo motor 33 is connected to the telescopic member 32;

[0049] The polishing wheel 34 is connected to a servo motor 33 .

[0050] A further refinement of the embodiment of the present invention also includes a timer, which is not shown in the figure. The timer can accurately limit the processing time of a flange sleeve 101. When the pre-set time is reached, the polishing is immediately ended, and then a new flange sleeve 101 can be replaced to start a new round of processing.

[0051] It should be noted that the drive motor 11 , the drive assembly, the telescopic member 32 , the servo motor 33 and the timer are all electrically connected to the controller, which is not shown in the figure.

[0052] The workflow of this utility model:

[0053] When the flange sleeve 101 is processed on the lathe, the processed flange sleeve 101 is placed steadily between the two rotating rollers 14. At this time, the outer surface of the flange sleeve 101 contacts the rubber layer 17, and the controller controls the driving component to work and drive the deflection rod 23 to slowly move in a circular motion (the deflection rod 23 is in a vertical state in the initial state so as not to affect the placement of the flange sleeve 101). Then the pressure roller 24 will slowly contact the upper surface of the flange sleeve 101, and the position of the flange sleeve 101 can be limited. After the position of the flange sleeve 101 is limited, the controller controls the telescopic part 32 to work and the polishing wheel 34 moves to the inner part of the flange sleeve 101. The inner diameter of the flange sleeve 101 is in the middle and in contact with the local part, and then the controller controls the servo motor 33 to work to realize the high-speed rotation of the polishing wheel 34, and at this time, the local polishing of the inner diameter of the flange sleeve 101 can be realized. At the same time, the controller controls the drive motor 11 to work, and after the drive motor 11 works, the two rotating rollers 14 can be synchronously rotated in the same direction through the belt transmission mode, and then the flange sleeve 101 can be rotated to change the polishing position, and then the polishing wheel 34 can realize the circumferential polishing of the inner diameter of the flange sleeve 101. Subsequently, the penetration depth of the polishing wheel 34 can be changed according to the pre-set motion trajectory of the telescopic member 32, and finally the automatic polishing process of the inner diameter of the flange sleeve 101 is realized;

[0054] Compared with the existing technology, this device does not require manual labor to hold 600# sandpaper to press the high-speed rotating flange sleeve for inner diameter polishing, thereby significantly reducing the safety hazards in the polishing process, and significantly improving the degree of automation of polishing. At the same time, the probability of surface wear of the flange sleeve when fixing it is significantly reduced, and the probability of surface damage of the flange sleeve during the entire polishing process is greatly reduced, and the polishing effect is better.

[0055] In some embodiments, as Figure 1 As shown, a distance sensor 18 is provided on the fixed plate 13;

[0056] In a further optimization of the above embodiment, a voice prompter electrically connected to the distance sensor 18 is further provided on the fixed plate 13. The voice prompter is not shown in the figure and belongs to the existing technology and no improvement is made. This embodiment can accurately define the placement area of the flange sleeve 101 on the rotating roller 14 through the distance sensor 18. When the distance sensor 18 detects that the distance range between the flange sleeve 101 and it reaches a preset numerical range, it will immediately feedback a signal to the controller, and then the controller controls the voice prompter and the drive assembly to work in sequence. The voice prompter can remind the placement personnel that the flange sleeve 101 has been placed in place at this time, and the drive assembly can drive the deflection rod 23 to move slowly and then realize the upper position limitation of the flange sleeve 101 through the pressure roller 24, so as to avoid the flange sleeve 101 from moving up and down during the subsequent polishing process.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
