Inside the device housing, there are a positioning assembly, a trimming assembly, and a discharging assembly. The positioning assembly includes a mounting seat, a downward pressing mechanism, an upward pushing mechanism, a transmission mechanism, and a driving mechanism. The mounting seat is slidably connected to the top of the device housing; the motor drives the downward pressing mechanism and the upward pushing mechanism to move towards each other through the transmission mechanism. The downward pressing mechanism utilizes a limiting disk, and the upward pushing mechanism relies on a supporting block to quickly complete the positioning and clamping of the hub. After positioning, the limiting disk drives the driven block to engage with the driving block.

Description

Technical Field

[0001] The present invention relates to the technical field of accessory trimming, and particularly relates to an efficient trimming device for processing automotive accessories. Background Art

[0002] In the manufacturing process of automotive wheels, due to the influence of casting or forging processes, defects such as flash and burrs often appear on the wheel edges. These defects not only damage the appearance of the wheels but may also scratch the tires, affect the tire sealing performance, cause air leakage, and thus reduce the service life of the tires and threaten driving safety. Therefore, it is necessary to use a professional trimming device to process the wheel edges to eliminate the above defects, ensure that the wheel quality meets the standards, and then improve the comprehensive performance of automotive wheels.

[0003] In the existing wheel trimming process, the wheel is placed on the working platform. After being fixed by the clamping component, the trimming component is started to rotate around the wheel to perform the trimming and grinding operation of the wheel. However, this trimming method mainly relies on manual operation to position the wheel on the working platform, which not only significantly increases the manual labor intensity and operation risk but also greatly reduces the trimming efficiency. In addition, due to the lack of coordination between the wheel and the clamping component, when replacing wheels of different specifications, it is necessary to debug the clamping component and the trimming component in sequence to ensure the normal trimming of the wheel. However, this operation mode seriously affects the operation efficiency of the device, and it is very easy to have deviations during the adjustment process, which will have a negative impact on the trimming quality.

[0004] Therefore, it is necessary to provide an efficient trimming device for processing automotive accessories to solve the above problems. Summary of the Invention

The driving shaft is fixedly connected to the output shaft of the motor through a coupling.

[0013] As a further improvement of the above solution, the trimming assembly includes fixed seats symmetrically and fixedly connected to the inside of the bracket. A grinding seat is slidably connected to the inside of the fixed seat. A bidirectional lead screw is rotatably connected to the inside of the fixed seat.

[0014] As a further improvement of the above solution, the discharging assembly includes conveying rollers and a cleaning belt.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] 1. The motor drives the downward pressing mechanism and the upward pushing mechanism to move towards each other through the transmission mechanism. The downward pressing mechanism utilizes the limiting disk and the upward pushing mechanism relies on the supporting block to quickly complete the positioning and clamping of the hub. After positioning, the limiting disk drives the driven block to engage with the driving block. Immediately afterwards, the driving block drives, through the movable sleeve, the clamping block to disengage from the driving sleeve. At this time, the motor drives the limiting disk to rotate alone through the driving shaft, driving the clamped hub to rotate, providing support for the stable trimming of the trimming assembly. In addition, the device can conveniently replace the limiting disk, the supporting block and the grinding block, ensuring both the trimming quality and significantly improving the trimming efficiency.

[0022] 2. The transmission shaft in the transmission mechanism can also drive the bidirectional lead screw to rotate. The bidirectional lead screw, through the slider and the push rod, pushes the grinding seat to slide inside the fixed seat, causing the grinding block to closely fit the hub. At the same time, the third spring provides a buffer space, effectively avoiding excessive force during trimming and ensuring the trimming quality. In addition, the device supports replacing the two grinding blocks with different meshes to meet different trimming precision requirements, optimizing the grinding effect and further improving the trimming efficiency and quality.

[0023] 3. During the hub transportation process, the conveying roller and the supporting roller cooperate to smoothly deliver the hub to the trimming station. The debris generated during the trimming process will fall to the top of the support plate. At this time, the cleaning belt drives the cleaning block to rotate, which can push these debris out of the device housing, automatically completing the internal cleaning work of the device, maintaining the cleanliness inside the device housing, reducing the potential impact of debris on the operation of the equipment, and ensuring the long-term stable operation of the equipment.

Detailed implementation manner

[0040] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0041] Please refer to Figures 1 to 14 As shown in the figure, the present invention provides an embodiment:

[0042] An efficient trimming device for processing auto parts, including a device housing 1. Inside the device housing 1, there are arranged a positioning assembly 5, a trimming assembly 6 and a discharging assembly 7. The positioning assembly 5 includes a mounting seat 51, a downward pressing mechanism 53, an upward pushing mechanism 54, a transmission mechanism 55 and a driving mechanism 56. The mounting seat 51 is slidably connected to the top of the device housing 1, and a bracket 52 is fixedly connected inside the device housing 1;

[0043] The pressing-down mechanism 53 includes a lower pressing plate 531, a movable rod 532 and a limiting disc 534. The limiting disc 534 is fixedly connected to the bottom of the movable rod 532. A positioning block 533 is fixedly connected to the bottom of the lower pressing plate 531 through a limiting shaft 536. An installation disc 538 is rotatably connected to the outer side of the movable rod 532. The installation disc 538 is slidably connected to the outer side of the limiting shaft 536. A first spring 537 is fixedly connected between the installation disc 538 and the lower pressing plate 531. Connecting plates 59 are symmetrically and fixedly connected between the lower pressing plate 531 and the installation base 51;

[0044] The upward pushing mechanism 54 includes an upper fixed plate 541, a fixed rod 542 and a supporting block 543. The fixed rod 542 is fixedly connected to the top of the upper fixed plate 541. The fixed rod 542 and the supporting block 543 are rotatably connected;

[0045] The transmission mechanism 55 includes a unidirectional lead screw 553 and a driving sprocket 555. Two unidirectional lead screws 553 are provided as a group, and the two unidirectional lead screws 553 in each group respectively and independently form a helical pair transmission with the lower pressing plate 531 and the upper fixed plate 541. The driving sprocket 555 is rotatably connected to the inside of the installation base 51;

[0046] The transmission mechanism 55 further includes a transmission shaft 551 that is symmetrically and rotatably connected inside the device housing 1. The unidirectional lead screw 553 and the bidirectional lead screw 62 are both fixedly connected to the outer side of the transmission shaft 551. Driven sprockets 554 are symmetrically and rotatably connected to the inside of the installation base 51. A chain drive is formed between the driving sprocket 555 and the two driven sprockets 554 through a transmission chain 552. The driven sprocket 554 is slidably installed on the outer side of the transmission shaft 551 through a spline;

[0047] The driving mechanism 56 includes a driving shaft 561 that is rotatably connected to the inside of the device housing 1. A driving sleeve 563 is fixedly connected to the inside of the driving sprocket 555. A movable sleeve 562 penetrates through the inside of the driving sleeve 563. The driving shaft 561 is slidably connected to the inside of the movable sleeve 562. A connecting disc 568 is slidably connected to the outer side of the movable sleeve 562. Blocks 565 are evenly fixedly connected to the bottom of the connecting disc 568. The blocks 565 are slidably connected to the inside of the driving sleeve 563;

[0048] A fixed disc 566 is fixedly connected to the outer side of the movable sleeve 562. Limiting rods 569 are symmetrically fixedly connected to the bottom of the fixed disc 566. A second spring 567 is fixedly connected between the connecting disc 568 and the fixed disc 566. The connecting disc 568 is slidably connected to the outer side of the limiting rods 569;

[0049] A driven block 535 is fixedly connected to the top of the movable rod 532. A driving block 564 is fixedly connected to the bottom of the movable sleeve 562. The driven block 535 and the driving block 564 are mutually engaged;

[0050] At the top of the device housing 1, a motor 4 is fixedly installed, and the drive shaft 561 is fixedly connected to the output shaft of the motor 4 through a coupling.

[0051] In the actual application of the embodiment of the present invention, as Figure 5 , Figure 7 , Figure 8 and Figure 11 shown, when the hub is conveyed into the device housing 1 between the pressing mechanism 53 and the top pressing mechanism 54, the motor 4 is started. The motor 4 drives the drive shaft 561 to rotate through the coupling. Since the drive shaft 561 is in sliding connection with the movable sleeve 562, the rotation of the drive shaft 561 drives the movable sleeve 562 to rotate. The block 565 on the outer side of the movable sleeve 562 meshes with the drive sleeve 563, thereby driving the drive sleeve 563 and the driving sprocket 555 fixedly connected thereto to rotate. The driving sprocket 555 drives the driven sprockets 554 at both ends to rotate synchronously through the transmission chain 552. The driven sprocket 554 drives the transmission shaft 551 connected thereto to rotate through the spline, and the rotation of the transmission shaft 551 further drives the one-way lead screw 553 to rotate;

[0052] As Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Figure 10 and Figure 14 shown, the one-way lead screw 553 forms a helical pair transmission relationship with the lower pressing plate 531 and the upper fixed plate 541 respectively. As the one-way lead screw 553 rotates, the lower pressing plate 531 and the upper fixed plate 541 start to move towards each other. Since the lower pressing plate 531 is rotatably connected to the mounting disk 538 through the limiting shaft 536 and the first spring 537 with a movable rod 532, when the lower pressing plate 531 moves downward, it will drive the limiting disk 534 to move downward together through the movable rod 532; at the same time, the upper fixed plate 541 moves upward, driving the fixed rod 542 and the support block 543 to rise synchronously. Finally, the limiting disk 534 and the support block 543 clamp the hub. During the clamping process, the limiting disk 534 and the support block 543 are in close contact with the hub center hole through their inclined surfaces, which not only ensures the stability of the clamping but also accurately fixes the clamping position of the hub;

[0053] As Figure 3 , Figure 4 , Figure 5 , Figure 8 and Figure 9As shown, as the clamping action continues, after the limit disc 534 contacts the hub, it will block the limit disc 534 and the movable rod 532 from moving downward continuously. However, since the lower pressing plate 531 is fixedly connected to the mounting base 51 through the connecting plate 59, the mounting base 51 will drive the driving sprocket 555, the driven sprocket 554 and the transmission chain 552 to continue moving downward. During the downward movement of the driving sprocket 555, it drives the driving sleeve 563 to move downward synchronously, causing the driving sleeve 563 to disengage from the engaging block 565. The state at this time is as Figure 7 shown. After that, the rotation of the drive shaft 561 and the movable sleeve 562 will only drive the engaging block 565 to move upward repeatedly. After squeezing the second spring 567, it will reset. And the driven block 535 at the top of the movable rod 532 is clamped with the driving block 564 at the bottom of the movable sleeve 562. Therefore, the movable sleeve 562 can drive the limit disc 534 to rotate, thereby realizing the rotation of the hub within the device housing 1, so as to cooperate with the trimming assembly 6 to trim and polish the hub;

[0054] As Figures 3 to 5 , Figures 8 to 10 shown. After the grinding process is completed, the motor 4 is started again to drive the drive shaft 561 to rotate in the reverse direction. Since the drive shaft 561 is slidably connected to the movable sleeve 562, the reverse rotation of the drive shaft 561 drives the movable sleeve 562 to rotate in the reverse direction accordingly. At this time, under the action of the elastic restoring force of the second spring 567 and its own special structure design, the engaging block 565 re-engages with the driving sleeve 563 and drives the driving sleeve 563 to rotate in the reverse direction. The reverse rotation of the driving sleeve 563 causes the driving sprocket 555 connected to it to rotate in the reverse direction. The driving sprocket 555 drives the driven sprocket 554 to rotate in the reverse direction through the transmission chain 552. Furthermore, the transmission shaft 551 rotates in the reverse direction. The reverse rotation of the transmission shaft 551 drives the one-way lead screw 553 to rotate in the reverse direction. The one-way lead screw 553 drives the lower pressing plate 531 and the upper fixing plate 541 to move away from each other through the screw pair transmission, and the limit disc 534 and the support block 543 gradually move away, realizing the loosening of the clamping of the hub, so that the subsequent hub can be smoothly removed from the device housing 1;

[0055] When it is necessary to replace hubs of different specifications, the corresponding limit disc 534 and support block 543 can be conveniently replaced, so as to meet the positioning requirements of hubs of different specifications. Cooperating with the trimming assembly 6 can not only ensure the trimming quality but also significantly improve the trimming efficiency.

[0056] As Figure 1 and Figure 2 shown, roller conveyors 2 are symmetrically and fixedly installed on the outer side of the device housing 1, and legs 3 are fixedly connected to the four corners of the bottom of the device housing 1.

[0057] In the actual application of the embodiment of the present invention, the roller feeder 2 transports the hub stably and efficiently into the device housing 1 by virtue of the frictional force with the hub, and accurately positions it at the designated trimming station between the downward pressing mechanism 53 and the upward pushing mechanism 54. During the entire trimming process, the legs 3 fixedly connected to the four corners of the bottom of the device housing 1 provide stable and reliable support for the entire device.

[0058] As Figures 3 to 6 shown, the trimming assembly 6 includes fixed seats 61 symmetrically and fixedly connected inside the bracket 52. A grinding seat 65 is slidably connected inside the fixed seat 61. A bidirectional lead screw 62 is rotatably connected inside the fixed seat 61. Two sliders 63 are symmetrically and slidably connected inside the fixed seat 61. A screw pair drive is formed between the slider 63 and the bidirectional lead screw 62. A push rod 64 is rotatably connected between the slider 63 and the grinding seat 65. A grinding block 66 is slidably installed inside the grinding seat 65. A third spring 67 is fixedly connected to the inner wall of the grinding seat 65.

[0059] In the actual application of the embodiment of the present invention, the drive shaft 551 in the drive mechanism 55 drives the bidirectional lead screw 62 to rotate inside the fixed seat 61. Since a screw pair drive is formed between the slider 63 and the bidirectional lead screw 62, as the bidirectional lead screw 62 rotates, the two sliders 63 slide symmetrically in opposite directions inside the fixed seat 61. The sliding of the slider 63 transmits power through the push rod 64, pushing the grinding seat 65 to slide towards the hub inside the fixed seat 61 until the grinding block 66 installed inside the grinding seat 65 is in close contact with the hub. When the hub is accurately clamped, as the hub continues to rotate, the grinding block 66 performs trimming and grinding operations on the edge of the hub;

[0060] During the grinding process, when the grinding block 66 comes into contact with an uneven part of the hub or encounters a large resistance, the third spring 67 can provide buffering through its own elastic deformation, avoiding damage to the hub caused by excessive grinding force and ensuring the trimming quality. At the same time, the third spring 67 can also keep the grinding block 66 in close contact with the hub all the time, improving the uniformity and stability of trimming;

[0061] In addition, when trimming work with different roughness requirements is required, different meshes of grinding blocks 66 can be conveniently replaced inside the grinding seat 65 to meet diverse trimming needs and further improve the trimming efficiency and quality.

[0062] As Figure 3 、 Figure 4 、 Figure 12 and Figure 13As shown in the figure, the blanking assembly 7 includes a conveying roller 71 and a cleaning belt 72. The conveying roller 71 is evenly rotatably connected to the inside of the bracket 52. The bottom of the bracket 52 is symmetrically rotatably connected with driving rollers 75. The cleaning belt 72 is drivingly connected between the two driving rollers 75. Cleaning blocks 74 are evenly fixedly connected to the outer side of the cleaning belt 72. A power shaft 76 is rotatably connected to the inside of the device housing 1. Worms 77 are evenly fixedly connected to the outer side of the power shaft 76. A worm gear 73 is fixedly connected to the outer side of the conveying roller 71. The worm 77 meshes with the worm gear 73. Driving wheels 79 are fixedly connected to the outer sides of the conveying roller 71 and the cleaning belt 72. A transmission belt 78 is sleeved between the driving wheels 79.

[0063] In the actual application of the embodiment of the present invention, when the hub trimming operation starts, the power shaft 76 rotates, and the worms 77 evenly fixedly connected to the outer side of the power shaft 76 rotate synchronously. Since the worm 77 meshes with the worm gear 73 fixedly connected to the outer side of the conveying roller 71, the rotation of the worm 77 drives the worm gear 73, thereby driving the conveying roller 71 to rotate inside the bracket 52. The rotation of the conveying roller 71 is responsible for smoothly conveying the hub to the trimming station on the one hand, and on the other hand, through the driving wheel 79 fixedly connected to its outer side and the sleeved transmission belt 78, it drives the driving wheel 79 on the outer side of the cleaning belt 72 to rotate, so that the cleaning belt 72 circulates and drives between the two driving rollers 75;

[0064] During the trimming process, the debris generated by the hub trimming falls onto the conveying roller 71 and the bracket 52. As the cleaning belt 72 circulates and drives, the cleaning blocks 74 fixedly connected to its outer side continuously pass through the surfaces of the conveying roller 71 and the bracket 52. The cleaning blocks 74 gather the fallen debris, and with the movement of the cleaning belt 72, the debris is pushed out of the device housing 1, realizing the cleaning inside the device, maintaining the cleanliness inside the device, and preventing the accumulation of debris from affecting the normal operation of the equipment and the subsequent trimming quality of the hub.

[0065] As Figure 3 and Figure 5 shown in the figure, a support plate 58 is fixedly connected to the bottom of the bracket 52. Support rollers 57 are symmetrically rotatably connected between two fixed seats 61.

[0066] In the actual application of the embodiment of the present invention, during the trimming process, the debris ground off from the hub falls one after another. The support plate 58 can effectively receive these debris, prevent them from scattering everywhere, facilitate subsequent cleaning, and maintain the neatness inside the device; at the same time, during the process of transporting the hub to the trimming station, the support roller 57 and the conveying roller 71 cooperate with each other. The hub moves forward under the push of the conveying roller 71, and the support roller 57 provides a supporting force below the hub to ensure that the hub remains stable during the movement, avoiding shaking or deviation due to uneven local stress, so as to accurately position to the appropriate position of the trimming assembly 6, providing a stable foundation for the subsequent trimming operation.
