Description

Technical Field

[0001] The invention relates to the technical field of trimming of accessories, in particular to a high-efficiency trimming device for processing automobile accessories. Background Art

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

[0003] In the existing wheel hub trimming process, the wheel hub is placed on a work platform, and after being fixed with the help of a clamping assembly, the trimming assembly is started to rotate around the wheel hub to achieve the trimming and grinding operation of the wheel hub. However, this trimming method mainly relies on manual positioning of the wheel hub on the work platform, which not only significantly increases the labor intensity and operation risks, but also greatly reduces the trimming efficiency; in addition, due to the lack of coordination between the wheel hub and the clamping assembly, when replacing wheels of different specifications, the clamping assembly and the trimming assembly need to be debugged in turn to ensure the normal trimming of the wheel hub, but this operating mode seriously affects the operating efficiency of the device, and deviations are very likely to occur during the adjustment process, which in turn has a negative impact on the trimming quality.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The motor drives the pressing mechanism and the lifting mechanism to move toward each other through the transmission mechanism. The pressing mechanism uses the limit plate and the lifting mechanism relies on the support block to quickly complete the positioning and clamping of the wheel hub. After positioning, the limit plate drives the driven block to engage with the active block, and the active block then passes through the movable sleeve to disengage the clamping block from the driving sleeve.

[0016] 2. The transmission shaft in the transmission mechanism can also drive the bidirectional screw to rotate. The bidirectional screw pushes the grinding seat to slide in the fixed seat through the slider and the push rod, so that the grinding block fits the wheel hub closely. At the same time, spring three provides buffer space to effectively avoid excessive force during trimming and ensure the trimming quality. In addition, the device supports replacing the two grinding blocks with different mesh sizes to meet different trimming accuracy requirements, optimize the grinding effect, and further improve the trimming efficiency and quality.

[0017] 3. In the hub transportation process, the conveying roller and the supporting roller work together 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 the debris out of the device casing, automatically complete the internal cleaning of the device, keep the inside of the device casing clean, reduce the potential impact of debris on the operation of the equipment, and ensure the long-term stable operation of the equipment.

A spring 537 is fixedly connected between the mounting plate 538 and the pressing plate 531. A connecting plate 59 is symmetrically fixedly connected between the pressing plate 531 and the mounting seat 51. The lifting mechanism 54 includes an upper fixed plate 541, a fixing rod 542 and a support block 543. The fixing rod 542 is fixedly connected to the top of the upper fixed plate 541, and the fixing rod 542 and the support block 543 are rotatably connected. The transmission mechanism 55 includes a one-way screw rod 553 and a driving sprocket 555. The one-way screw rods 553 are arranged in two groups, and the two one-way screw rods 553 in each group are independently connected to the lower pressure plate 531 and the movable rod 532 to form a spiral pair transmission. The driving sprocket 555 is rotatably connected to the inside of the mounting seat 51. The transmission mechanism 55 also includes a lower pressure plate 531 symmetrically rotatably connected to the device housing 1, a one-way screw 553 and a two-way screw 62 are fixedly connected to the outer side of the lower pressure plate 531, and a driven sprocket 554 is symmetrically rotatably connected inside the mounting seat 51. A chain drive is formed between the driving sprocket 555 and the two driven sprockets 554 through a transmission chain 552, and the driven sprocket 554 is slidably mounted on the outer side of the transmission shaft 551 through a spline. The driving mechanism 56 includes a driving shaft 561 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 the inside of the driving sleeve 563, the driving shaft 561 is slidably connected to the inside of the movable sleeve 562, a connecting plate 568 is slidably connected to the outside of the movable sleeve 562, a clamping block 565 is evenly fixedly connected to the bottom of the connecting plate 568, and the clamping block 565 is slidably connected to the inside of the driving sleeve 563; The outer side of the movable sleeve 562 is fixedly connected with a fixed plate 566, the bottom of the fixed plate 566 is symmetrically fixedly connected with a limit rod 569, a spring 2 567 is fixedly connected between the connecting plate 568 and the fixed plate 566, and the connecting plate 568 is slidably connected to the outer side of the limit rod 569; The top of the movable rod 532 is fixedly connected with a driven block 535, and the bottom of the movable sleeve 562 is fixedly connected with an active block 564, and the driven block 535 and the active block 564 are mutually engaged; The motor 4 is fixedly mounted on the top of the device housing 1, and the drive shaft 561 is fixedly connected to the output shaft of the motor 4 through a coupling.

[0023] In practical application, the embodiment of the present invention is as follows: Figure 5 , Figure 7 , Figure 8 and Fig.11As shown, when the wheel hub is conveyed to between the pressing mechanism 53 and the lifting mechanism 54 in the housing 1 of the device, the motor 4 is started, and the motor 4 drives the driving shaft 561 to rotate through the coupling. Since the driving shaft 561 and the movable sleeve 562 are in sliding connection, the driving shaft 561 rotates and then drives the movable sleeve 562 to rotate. The block 565 on the outer side of the movable sleeve 562 engages with the driving sleeve 563, thereby driving the driving 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. The rotation of the transmission shaft 551 further drives the one-way screw rod 553 to rotate. like Figure 3 , Figure 4 , Figure 5 , Figure 7 , Figure 8 , Fig.10 and Fig.14 As shown, the one-way screw rod 553 forms a spiral pair transmission relationship with the lower pressure plate 531 and the upper fixed plate 541 respectively. As the one-way screw rod 553 rotates, the lower pressure plate 531 and the upper fixed plate 541 begin to move toward each other. Since the lower pressure plate 531 is rotatably connected to the movable rod 532 through the limiting shaft 536, the spring 1 537 and the mounting plate 538, when the lower pressure plate 531 moves downward, it will drive the limiting plate 534 to move downward together through the movable rod 532; at the same time, the upper fixed plate 541 moves upward, driving the fixing rod 542 and the supporting block 543 to rise synchronously, and finally the limiting plate 534 and the supporting block 543 achieve clamping of the wheel hub. During the clamping process, the limiting plate 534 and the supporting block 543 are tightly connected with the center hole of the wheel hub through their inclined surfaces, which not only ensures the stability of the clamping, but also accurately fixes the clamping position of the wheel hub. like Figure 3 , Figure 4 , Figure 5 , Figure 8 and Fig. 9 As shown, as the clamping action continues, the limit plate 534 contacts the wheel hub, which will prevent the limit plate 534 and the movable rod 532 from continuing to move downward. However, since the lower pressure plate 531 is fixedly connected to the mounting seat 51 through the connecting plate 59, the mounting seat 51 will drive the driving sprocket 555, the driven sprocket 554 and the transmission chain 552 to continue to move downward. During the downward movement of the driving sprocket 555, the driving sleeve 563 is driven to move downward synchronously, causing the driving sleeve 563 to disengage from the block 565. The state at this time is as shown in FIG. Figure 7As shown, the rotation of the drive shaft 561 and the movable sleeve 562 will only drive the clamping block 565 to move upward repeatedly, squeeze the spring 567 and then reset, and the driven block 535 at the top of the movable rod 532 is engaged with the active block 564 at the bottom of the movable sleeve 562, so the movable sleeve 562 can drive the limit plate 534 to rotate, thereby realizing the rotation of the wheel hub in the device housing 1, so as to cooperate with the trimming assembly 6 to perform trimming and grinding on the wheel hub; like Figures 3 to 5 , Figures 8 to 10 As shown, after the grinding process is completed, the motor 4 is started again to drive the driving shaft 561 to rotate in the opposite direction. Since the driving shaft 561 and the movable sleeve 562 are in sliding connection, the reverse rotation of the driving shaft 561 drives the movable sleeve 562 to rotate in the opposite direction. At this time, the block 565 re-engages with the driving sleeve 563 under the elastic restoring force of the second spring 567 and its own special structural design, and drives the driving sleeve 563 to reverse. The reverse rotation of the driving sleeve 563 causes the driving sprocket 555 connected thereto to rotate in the opposite direction. The driving sprocket 555 drives the driven sprocket 554 to rotate in the opposite direction through the transmission chain 552, thereby reversing the transmission shaft 551. The reverse rotation of the transmission shaft 551 drives the one-way screw rod 553 to rotate in the opposite direction. The one-way screw rod 553 is driven by the spiral pair to make the lower pressure plate 531 and the upper fixed plate 541 move away from each other, and the limit plate 534 and the support block 543 gradually move away from each other, so as to realize the loosening of the wheel hub clamping, so that the subsequent wheel hub can be smoothly moved out of the device housing 1. When it is necessary to replace a wheel hub of different specifications, the corresponding limit plate 534 and support block 543 can be easily replaced to meet the positioning requirements of wheel hubs of different specifications. In combination with the trimming assembly 6, the trimming quality can be guaranteed and the trimming efficiency can be significantly improved.

[0024] like Figure 1 and Figure 2 As shown, a roller conveyor 2 is symmetrically fixedly installed on the outer side of the device housing 1, and supporting legs 3 are fixedly connected to the four corners of the bottom of the device housing 1.

[0025] When the embodiment of the present invention is actually used, the roller conveyor 2 relies on the friction between the wheel hub and the roller conveyor 2 to smoothly and efficiently transport the wheel hub into the device housing 1, and accurately positions it at the designated trimming station between the pressing mechanism 53 and the lifting mechanism 54. During the entire trimming process, the legs 3 fixedly connected at the four corners of the bottom of the device housing 1 provide stable and reliable support for the entire device.

[0026] like Figures 3 to 6As shown, the trimming assembly 6 includes a fixed seat 61 symmetrically fixedly connected to the inside of the bracket 52, a grinding seat 65 is slidably connected inside the fixed seat 61, a bidirectional screw rod 62 is rotatably connected inside the fixed seat 61, a slider 63 is symmetrically slidably connected inside the fixed seat 61, a spiral pair transmission is formed between the slider 63 and the bidirectional screw rod 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, and a spring 67 is fixedly connected to the inner wall of the grinding seat 65.

[0027] In actual application of the embodiment of the present invention, the transmission shaft 551 in the transmission mechanism 55 drives the bidirectional screw 62 to rotate in the fixed seat 61. Since the slider 63 and the bidirectional screw 62 form a spiral pair transmission, as the bidirectional screw 62 rotates, the two sliders 63 slide symmetrically in opposite directions in the fixed seat 61. The sliding of the slider 63 transmits power through the push rod 64, pushing the grinding seat 65 to slide in the fixed seat 61 toward the wheel hub until the grinding block 66 installed inside the grinding seat 65 fits tightly with the wheel hub. When the wheel hub is accurately clamped, as the wheel hub continues to rotate, the grinding block 66 performs trimming and grinding operations on the edge of the wheel hub. During the grinding process, when the grinding block 66 contacts an uneven part of the wheel hub or encounters a large resistance, the spring three 67 can provide a buffer through its own elastic deformation to avoid damage to the wheel hub caused by excessive grinding force, thereby ensuring the trimming quality. At the same time, the spring three 67 can also keep the grinding block 66 in close contact with the wheel hub at all times, thereby improving the uniformity and stability of the trimming. In addition, when trimming work with different roughness requirements is required, the grinding blocks 66 with different mesh sizes can be easily replaced from inside the grinding seat 65 to meet the diverse trimming needs and further improve the trimming efficiency and quality.

[0028] like Figure 3 , Figure 4 , Fig.12 and Fig.13 As shown, the discharge 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 to a transmission roller 75. The cleaning belt 72 is transmission-connected to the two transmission rollers 75. The outer side of the cleaning belt 72 is evenly fixedly connected to a cleaning block 74. The inside of the device housing 1 is rotatably connected. The outer side of the power shaft 76 is evenly fixedly connected to a worm 77. The outer side of the conveying roller 71 is fixedly connected to a worm wheel 73. The worm 77 and the worm wheel 73 are meshed with each other. The outer sides of the conveying roller 71 and the cleaning belt 72 are fixedly connected to transmission wheels 79, and a transmission belt 78 is sleeved between the transmission wheels 79.

[0029] In actual application, when the wheel hub trimming operation starts, the power shaft 76 rotates, and the worm 77 uniformly fixed on the outside of the power shaft 76 rotates synchronously therewith. Since the worm 77 and the worm wheel 73 fixed on the outside of the conveying roller 71 are meshed with each other, the rotation of the worm 77 drives the worm wheel 73, and then drives the conveying roller 71 to rotate inside the bracket 52. The rotation of the conveying roller 71 is responsible for smoothly conveying the wheel hub to the trimming station on the one hand, and on the other hand, the transmission wheel 79 on the outside of the cleaning belt 72 is driven to rotate through the transmission wheel 79 fixed on the outside and the sleeved transmission belt 78, so that the cleaning belt 72 is circulated and driven between the two transmission rollers 75; During the trimming process, the debris generated by the wheel hub trimming falls onto the conveying roller 71 and the bracket 52. As the cleaning belt 72 circulates, the cleaning block 74 fixed on its outer side continuously passes over the surface of the conveying roller 71 and the bracket 52. The cleaning block 74 gathers the fallen debris and pushes the debris out of the device housing 1 as the cleaning belt 72 moves, thereby cleaning the inside of the device, maintaining the cleanliness of the inside of the device, and preventing the accumulation of debris from affecting the normal operation of the equipment and the subsequent trimming quality of the wheel hub.

[0030] like Figure 3 and Figure 5 As shown, a support plate 58 is fixedly connected to the bottom of the bracket 52, and a support roller 57 is symmetrically rotatably connected between two fixing seats 61.

[0031] When the embodiment of the present invention is actually used, during the trimming process, the debris polished from the wheel hub falls down, and the support plate 58 can effectively receive these debris to prevent them from scattering everywhere, which is convenient for subsequent cleaning and keeps the interior of the device tidy; at the same time, during the transportation of the wheel hub to the trimming station, the support roller 57 and the conveying roller 71 cooperate with each other, and the wheel hub moves forward under the push of the conveying roller 71. The support roller 57 provides support force from below for the wheel hub, ensuring that the wheel hub remains stable during movement and avoiding shaking or deviation due to local uneven force, thereby accurately positioning the trimming assembly 6 at a suitable position to provide a stable foundation for subsequent trimming operations.
