Description

Technical Field

[0001] The present application relates to the technical field of track plate processing equipment, and in particular to a grinding device for track plate processing. Background Art

[0002] Track shoes are one of the chassis parts of engineering machinery and are also a kind of vulnerable parts. Track shoes are usually made by casting, so there will be metal burrs on the pin ear holes, pin ear grooves and edge edges of the track shoes. In order to make the assembly between track shoes less susceptible to the influence of burrs, the burrs on the track shoes need to be polished.

[0003] Existing track plate grinding devices are usually only capable of grinding one of the pin ear holes, pin ear grooves or edge ridges. For example, Chinese patent publication number CN116021368A discloses a track plate fast grinding machine, which can grind the pin ear grooves of the track plate. For example, Chinese patent publication number CN221735747U discloses a mechanical edge grinding device for track plate processing with a flipping function, which can perform edge grinding on the track plate.

[0004] Since the above solution can only grind a single portion of the track shoe, the overall grinding efficiency of the track shoe is reduced, which is not conducive to the mass production of the track shoe. Summary of the Invention

[0032] The following is combined with Figure 1-4 This application is described in further detail.

[0033] The embodiment of the present application discloses a grinding device for track plate processing. Figure 1A grinding device for track shoe processing includes a frame 1, a rotating component 2, a hole grinding component 3, a supporting component 4, a groove grinding component 5, an edge grinding component 6 and a magnetic drive component 7.

[0034] Reference Figure 2 A support disc 11 and a support ring 12 are rotatably mounted on the frame 1. The support disc 11 and the support ring 12 are disposed opposite each other and coaxially. A rotating assembly 2 is connected to the frame 1, the support disc 11, and the support ring 12, respectively, and is used to drive the support disc 11 and the support ring 12 to rotate synchronously.

[0035] Reference Figure 3 The hole grinding assembly 3 includes a support rod 31 , a support block 32 , a grinding rod 33 and a hole grinding motor 34 .

[0036] Reference Figure 2 and Figure 3 Two support rods 31 are provided, and both are rotatably mounted on the support plate 11. The two support rods 31 are respectively configured to be mounted in all the pin holes on each side of the track shoe, and the support rods 31 are rotatably connected to the track shoe. Multiple groups of support blocks 32 are provided, and are respectively mounted on the two support rods 31. The multiple groups of support blocks 32 correspond one-to-one with all the pin holes on the track shoe. Each group of support blocks 32 is provided with three support blocks 32 surrounding the corresponding support rod 31. The three support blocks 32 are evenly arranged around the support rod 31 and are fixedly connected to the support rod 31.

[0037] There are multiple grinding rods 33, each of which is fixedly connected to the side of the support block 32 away from the support rod 31. The grinding rods 33 are round rod-shaped, and their axes are parallel to the axes of the support rod 31. The grinding rods 33 are used to make linear contact with the wall of the pin ear hole. Since the grinding rods 33 and the pin ear hole are in linear contact, the grinding rods 33 can easily fit the wall of the pin ear hole and be inserted into the pin ear hole. The grinding motor 34 is fixedly connected to the support plate 11 and is located on the side of the support plate 11 away from the support rod 31. There are two grinding motors 34, each of which is fixedly connected to one end of the support rod 31. The output shaft of the grinding motor 34 is fixedly connected to the end of the support rod 31.

[0038] Reference Figure 2 The support assembly 4 is arranged on the support ring 12, and the support assembly 4 is used to reserve space for the track shoe to be loaded and unloaded on the two support rods 31, and the support assembly 4 is used to provide supporting force to the ends of the support rods 31 when the track shoe is installed on the two support rods 31.

[0039] Reference Figure 3 and Figure 4There are multiple groups of grinding groove assemblies 5, which are respectively arranged on two support rods 31. The grinding groove assemblies 5 correspond one-to-one to the pin ear grooves on the track shoe. The grinding groove assembly 5 includes a grinding plate 51 and a rebound part 52. There are three grinding plates 51 and three rebound parts 52 around the support rod 31, and they correspond one to one. The rebound part 52 elastically connects the grinding plate 51 and the support rod 31. The speed output by the grinding motor 34 changes sinusoidally, so that the grinding plate 51 can slide close to and away from the support rod 31 cyclically under the action of centrifugal force.

[0040] Reference Figure 4 When the support rod 31 is stationary, the rebound portion 52 is used to drive the grinding plate 51 to pass through the pin ear hole. In this embodiment, at this time, the three grinding plates 51 can together form a complete circular tube. When the rotation speed of the support rod 31 reaches the maximum, the grinding plate 51 can just grind the bottom of the pin ear groove.

[0041] Reference Figure 2 and Figure 3 The edge grinding assembly 6 includes a edge grinding motor 61, a flexible grinding roller 62 and a sliding drive part 63. The edge grinding motor 61 is slidingly set on the support plate 11 with a waist-shaped track. The flexible grinding roller 62 is connected to the output shaft of the edge grinding motor 61. The sliding drive part 63 is used to drive the edge grinding motor 61 to slide with the help of the rotational force output by the edge grinding motor 61. The flexible grinding roller 62 is used to squeeze on the outer surface of the track shoe.

[0042] Among them, reference Figure 3 A grinding shaft 613 is fixedly connected to the output shaft of the grinding motor 61, and the flexible grinding roller 62 is sleeved on the grinding shaft 613 and fixedly connected to the grinding shaft 613. The grinding shaft 613 realizes the connection between the flexible grinding roller 62 and the output shaft of the grinding motor 61; in this embodiment, the interior of the flexible grinding roller 62 is made of sponge and the outer surface is made of diamond.

[0043] Reference Figure 2 The magnetic drive assembly 7 is arranged on the support plate 11 , and the magnetic drive assembly 7 is used to drive the track shoe to be loaded and unloaded on the two support rods 31 .

[0044] During use, the magnetic drive assembly 7 drives the track shoe to move, so that the support rod 31 is passed through the pin ear hole, and the grinding rod 33 abuts against the hole wall of the pin ear hole to support the entire track shoe. The support assembly 4 provides supporting force to the ends of the two support rods 31, so that the two support rods 31 can stably support the track shoe, and the grinding motor 34 drives the support rod 31 to rotate, and the support rod 31 drives the grinding rod 33 to rotate, so that the grinding rod 33 can grind the pin ear hole.

[0045] The rotating assembly 2 drives the support plate 11 and the support ring 12 to rotate synchronously, and the support plate 11 and the support ring 12 drive the two support rods 31 to carry the track shoe to flip, so as to avoid the grinding rod 33 grinding excessively on one side of the pin ear hole wall on the track shoe due to the gravity of the track shoe, so that the pin ear hole can be evenly ground.

[0046] Since the rotational speed output by the grinding motor 34 changes sinusoidally, the grinding plate 51 can receive the sinusoidally changing centrifugal force. Driven by the sinusoidally changing centrifugal force, the grinding plate 51 can slide towards and away from the support rod 31 in a cycle. During the sliding process, the grinding plate 51 grinds the groove wall and groove bottom of the pin ear groove.

[0047] The edge grinding motor 61 drives the flexible grinding roller 62 to rotate. Under the drive of the sliding drive part 63, the edge grinding motor 61 drives the flexible grinding roller 62 to rotate around the track shoe. Since the flexible grinding roller 62 can be squeezed on the outer surface of the track shoe, the flexible grinding roller 62 can grind the outer surface and edge of the track shoe during the process of rotating around the track shoe.

[0048] Based on the above analysis, under the joint action of the hole grinding assembly 3, the groove grinding assembly 5 and the edge grinding assembly 6, the pin ear holes, pin ear grooves and edge edges of the track plate can be ground and deburred at the same time, thereby improving the overall grinding efficiency of the track plate and facilitating the mass production of the track plate.

[0049] Reference Figure 2 In order to enable the grinding rod 33 to be inserted exactly into the corresponding pin ear hole, the grinding hole assembly 3 also includes a positioning block 35. Two positioning blocks 35 are provided and are both fixedly connected to the support plate 11. The two support rods 31 are rotated and passed through the positioning blocks 35 in a one-to-one correspondence. The positioning blocks 35 are used to abut against the end surface of the track shoe. When the positioning blocks 35 abut against the end surface of the track shoe, the grinding rod 33 is exactly located in its corresponding pin ear hole.

[0050] Driven by the magnetic drive assembly 7, the end face of the track shoe can abut against the positioning block 35, so that the grinding rod 33 can be exactly located in its corresponding pin ear hole. At the same time, when the grinding rod 33 corresponds to the pin ear hole, the grinding plate 51 can also be exactly located in its corresponding pin ear groove.

[0051] Reference Figure 2In order to be able to grind the end of the track shoe, both ends of the flexible grinding roller 62 are integrally connected with end surface grinding rollers 621. The end surface grinding rollers 621 are used to grind the end surface of the track shoe. The magnetic drive assembly 7 includes a driving cylinder 71 and an electromagnet 72. The driving cylinder 71 is fixedly connected to the support plate 11, and the electromagnet 72 is fixedly connected to the movable end of the driving cylinder 71. When the track shoe abuts against the positioning block 35, the electromagnet 72 can be separated from the track shoe under the drive of the driving cylinder 71, so that the electromagnet 72 and the end surface of the track shoe are in a non-contact magnetic connection state.

[0052] The driving cylinder 71 can drive the electromagnet 72 to move. The electromagnet 72 can drive the track shoe to be installed on the two support rods 31 through magnetic attraction, and can drive the track shoe to be unloaded from the two support rods 31 through thrust, thereby facilitating the loading and unloading of the track shoe on the two support rods 31; since a non-contact magnetic attraction can be formed between the electromagnet 72 and the track shoe, after the track shoe is pressed against the positioning block 35, a space can be formed between the electromagnet 72 and the track shoe for the end face grinding roller 621 to move, so that when the flexible grinding roller 62 is grinding the edge edge, the end face of the track shoe can be simultaneously ground by the end face grinding roller 621, thereby enhancing the overall grinding effect of the track shoe.

[0053] Reference Figure 2 and Figure 3 In order to prevent the flexible grinding roller 62 and the end face grinding roller 621 from causing obstacles to the loading and unloading of the track shoe, the edge grinding motor 61 is hinged with a sliding seat 611, and the sliding seat 611 is slidably set in a waist-shaped slide groove 111 opened on the support plate 11. A swing electric cylinder 612 is set between the sliding seat 611 and the edge grinding motor 61. The swing electric cylinder 612 is hinged on the sliding seat 611, and the movable end of the swing electric cylinder 612 is hinged on the edge grinding motor 61. The swing electric cylinder 612 is used to drive the flexible grinding roller 62 to swing in the direction away from the track shoe.

[0054] When the track shoe is being loaded and unloaded, the swing electric cylinder 612 is extended, and the swing electric cylinder 612 drives the edge grinding motor 61 to deflect in the direction away from the track shoe. The edge grinding motor 61 can drive the flexible grinding roller 62 to swing in the direction away from the track shoe through the edge grinding shaft 613, so that the flexible grinding roller 62 and the end grinding roller 621 can be away from the track shoe, making it difficult for the flexible grinding roller 62 and the end grinding roller 621 to cause obstacles to the loading and unloading of the track shoe.

[0055] Specifically, refer to Figure 2 and Figure 3 The sliding drive part 63 includes a waist-shaped ring gear 631 and a surrounding gear 632. The waist-shaped ring gear 631 is sleeved on the two support rods 31 and fixedly connected to the support plate 11. The surrounding gear 632 is fixedly connected to the output shaft of the edge grinding motor 61. The surrounding gear 632 is engaged with the waist-shaped ring gear 631.

[0056] When the edge grinding motor 61 drives the flexible grinding roller 62 to rotate, the edge grinding motor 61 synchronously drives the surrounding gear 632 to rotate. Since the surrounding gear 632 is engaged with the waist-shaped ring gear 631, the waist-shaped ring gear 631 can drive the edge grinding motor 61 to slide, so that the edge grinding motor 61 can drive itself to slide by relying on the rotational force output by itself.

[0057] Specifically, refer to Figure 4 The rebound part 52 includes a telescopic rod 521 and a spring 522. The telescopic rod 521 is fixedly connected to the support rod 31. The movable end of the telescopic rod 521 is fixedly connected to the polishing plate 51. The telescopic direction of the telescopic rod 521 is perpendicular to the axial direction of the support rod 31. The spring 522 is arranged in the telescopic rod 521. One end of the spring 522 is fixedly connected to the telescopic rod 521, and the other end is fixedly connected to the movable end of the telescopic rod 521. The spring 522 is used to drive the telescopic rod 521 to retract.

[0058] When the support rod 31 is inserted into the pin ear hole, the support rod 31 is in a stationary state. Under the action of the elastic force of the spring 522, all the grinding plates 51 can be contracted into a complete circular tube that can pass through the pin ear hole, so that the support rod 31 can be easily inserted into all the corresponding pin ear holes; when the support rod 31 rotates at a sinusoidal speed, the grinding plate 51 can pull the telescopic rod 521 out under the drive of centrifugal force, and make the spring 522 accumulate elastic force. Under the cooperation of the spring 522 and the centrifugal force, the grinding plate 51 can slide in a cycle in the pin ear groove.

[0059] Specifically, refer to Figure 2 and Figure 3 The support assembly 4 includes a support cylinder 41 and a support bar 42. There are two support cylinders 41 and two support bars 42 symmetrically arranged, and they correspond one to one. The support cylinder 41 is fixedly connected to the inner wall of the support ring 12, and the support bar 42 is fixedly connected to the movable end of the support cylinder 41. Two support slots 421 are provided on the support bar 42. The support slots 421 pass through the support bar 42, and the two support slots 421 are used to be clamped on the two support rods 31 respectively.

[0060] When the track shoe needs to be loaded and unloaded, the two supporting cylinders 41 are retracted, and the supporting cylinders 41 can drive the supporting bar 42 away from the supporting rod 31 to leave space for the track shoe to move, so that the track shoe can be loaded and unloaded; when the track shoe needs to be polished, the two supporting cylinders 41 are extended, and the supporting cylinders 41 can drive the supporting bar 42 to approach the supporting rod 31, and the supporting slots 421 are clamped on the corresponding supporting rod 31 to form a rotary support for the support rod 31.

[0061] Reference Figure 3In order to prevent the rotation of the support rod 31 from being obstructed by the support bar 42, a support sleeve 311 is nested on the end of the support rod 31 away from the support plate 11. The support sleeve 311 is rotatably connected to the support rod 31, and the support slot 421 is used to be clamped on the support sleeve 311.

[0062] Since the support slot 421 can be clamped on the support sleeve 311 , the rotation of the support rod 31 is not easily affected by the clamping support force of the support bar 42 through the support sleeve 311 .

[0063] Specifically, refer to Figure 2 The rotating assembly 2 includes a rotating motor 21 , a rotating shaft 22 , a rotating gear 23 and a rotating ring gear 24 .

[0064] The rotating motor 21 is fixedly connected to the frame 1, the rotating shaft 22 is fixedly connected to the output shaft of the rotating motor 21, and two rotating gears 23 and rotating ring gears 24 are provided, and they correspond one to one. The rotating gears 23 are engaged with the rotating ring gears 24, and the rotating gears 23 are fixedly connected to the rotating shaft 22. One of the rotating ring gears 24 is fixedly connected to the support plate 11, and the other rotating ring gear 24 is fixedly connected to the support ring 12.

[0065] The rotating motor 21 can synchronously drive the two rotating gears 23 to rotate via the rotating shaft 22 , so that the two rotating gears 23 can synchronously drive the two rotating ring gears 24 to rotate, thereby enabling the support plate 11 and the support ring 12 to rotate synchronously.

[0066] Reference Figure 1 In order to facilitate the loading and unloading of the track shoes, a conveyor belt 13 is provided on the side of the support ring 12 away from the support plate 11, and the conveyor belt 13 is used to transport the track shoes one by one.

[0067] The track shoes are supplied to the support rods 31 through the conveyor belt 13, which reduces the labor intensity of manually moving the track shoes and improves the automation level of track shoe grinding, thereby facilitating batch grinding of the track shoes.

[0068] The implementation principle of a grinding device for track plate processing in an embodiment of the present application is as follows: when in use, the conveyor belt 13 conveys the track plates one by one to the support ring 12, causing the two support cylinders 41 to contract to open the two support bars 42, and the driving cylinder 71 drives the electromagnet 72 to move to the track plate. The electromagnet 72 drives the track plate to move through magnetic attraction, so that the support rod 31 is inserted into the pin ear hole until the track plate abuts against the positioning block 35, and the driving cylinder 71 drives the electromagnet 72 to separate from the track plate. Under the action of the magnetic attraction, the track plate stably abuts against the positioning block 35.

[0069] Start the hole grinding motor 34, the rotating motor 21 and the edge grinding motor 61. The hole grinding motor 34 drives the support rod 31 to rotate so that the grinding rod 33 grinds the pin ear hole and the grinding plate 51 grinds the pin ear groove. The rotating motor 21 drives the support plate 11 and the support ring 12 to rotate so that the track shoe can be flipped during the grinding process. The edge grinding motor 61 drives the flexible grinding roller 62 and the end face grinding roller 621 to rotate, and the edge grinding motor 61 drives itself to slide so that the flexible grinding roller 62 grinds the edge edge and the end face grinding roller 621 grinds the end face of the track shoe, so that the pin ear hole, pin ear groove, edge edge and end face of the track shoe can be grinded synchronously, thereby improving the overall grinding efficiency of the track shoe and facilitating the mass production of the track shoe.

[0070] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
