Description

Technical Field

[0001] The present invention relates to the technical field of grinding, and in particular to a steel plate grinding device. Background Art

[0002] Figure 1 One of the components is a steel plate. Four arc-shaped notches are arrayed on the outer periphery of the steel plate. Generally, manual grinding is adopted for grinding this steel plate. Because there are the following difficulties in realizing automatic grinding: the steel plate needs to be moved to a specific position at the grinding place, and each notch faces a specific direction, so that the grinding device can be moved to the four notches in turn under the action of the stroke mechanism to automatically grind the notches. If the steel plate is moved to the grinding place by an ordinary conveyor table, the position of the steel plate cannot be accurately controlled, nor can the orientation of the notch be accurately controlled, which affects the subsequent grinding task. In view of the above difficulties, the present invention provides a steel plate grinding device to solve the problems of low efficiency and inconsistent grinding effect of manual grinding. Summary of the Invention

[0003] To solve the deficiencies of the prior art, the present invention provides a steel plate grinding device, which can move the steel plate in a specific direction and to a specific position, and the notches of the steel plate also face a specific direction, so as to realize automatic grinding.

[0004] In order to achieve the purpose of the present invention, the following scheme is proposed:

[0005] A steel plate grinding device includes a conveyor belt, a plurality of limit members, an unlocking mechanism, a grinding table, and a translation mechanism.

[0006] A plurality of through holes are arrayed on the conveyor belt along the conveying direction;

[0007] Each limit member includes a sleeve, a limit post, and an L-shaped plate. The sleeve is fixedly arranged below the corresponding through hole. A circular plate is arranged at the bottom of the sleeve. The limit post is located in the through hole. A steel plate is placed between adjacent two limit posts, and the limit post matches the notch of the steel plate. Two grooves are arranged at the bottom of the limit post. A guide post is arranged in the groove. The guide post slides downward through the circular plate. A first spring is arranged on the outer periphery of the guide post. Two ends of the first spring are respectively connected to the circular plate and the limit post. The vertical section of the L-shaped plate is connected to the limit post;

[0008] The unlocking mechanism is arranged below the conveyor belt and includes a first lifting rod and a U-shaped pull rod arranged at the top thereof. The U-shaped groove of the U-shaped pull rod faces the horizontal direction of the L-shaped plate. The horizontal sections of adjacent two L-shaped plates are both located in the U-shaped groove. The first lifting rod is used to move the U-shaped pull rod downward to release the locking of the two limit posts on the steel plate;

[0009] The grinding table is located outside the conveyor belt. Four avoidance holes are arranged on its surface. A grinding device is arranged below the grinding table;

[0010] The translation mechanism is mounted above the conveyor belt and the grinding table through a support frame, and is used to translate the unlocked steel plate onto the grinding table, and the notch of the steel plate corresponds to the avoidance hole.

[0011] The beneficial effects of the present invention are as follows: A plurality of limiting members are provided on the conveyor belt. The structure of the limiting members is ingenious and is used to limit the steel plate to ensure that the steel plate will not move or rotate randomly during the conveying process. The unlocking mechanism is also very ingeniously matched with the limiting members. When the steel plate moves above the unlocking mechanism, the L-shaped plates of the two limiting members automatically move into the action range of the unlocking mechanism, so as to use the unlocking mechanism to pull down the L-shaped plates, thereby unlocking the locking of the two limiting members on the steel plate, and then using the translation mechanism to translate the steel plate onto the grinding table for grinding.

Detailed implementation manners

[0024] As Figure 1 , Figure 2 shown, this embodiment provides a steel plate grinding device, including a conveyor belt 1, a plurality of limiting members 2, an unlocking mechanism 3, a grinding table 4, and a translation mechanism 5.

[0025] Specifically, as Figure 1 , Figure 4 , Figure 5 shown, the plurality of limiting members 2 are arranged in an array along the conveying direction of the conveyor belt 1. The conveyor belt 1 is provided with a plurality of through - holes, and one through - hole corresponds to one limiting member 2. Each limiting member 2 includes a sleeve 21, a limiting post 22, and an L - shaped plate 23. The sleeve 21 is fixedly arranged below the corresponding through - hole and is coaxially arranged with it. Both the top and bottom of the sleeve 21 are open. A circular annular plate 211 is provided at the bottom of the sleeve 21. The limiting post 22 is located in the through - hole, and the top surface of the limiting post 22 is higher than the through - hole. A steel plate is placed between adjacent two limiting posts 22, and the limiting post 22 matches the notch of the steel plate for limiting the steel plate. The top of the limiting post 22 is provided with a rounded corner. Two grooves 221 are provided at the bottom of the limiting post 22. A guiding post 223 is arranged in the groove 221, and the guiding post 223 slides downward through the annular plate 211. A stop block with a diameter larger than that of the guiding post 223 can be arranged at the bottom of the guiding post 223 to prevent the guiding post 223 from detaching from the annular plate 211. A first spring 222 is arranged on the outer circumference of the guiding post 223, and both ends of the first spring 222 are respectively connected to the annular plate 211 and the limiting post 22. The vertical section of the L - shaped plate 23 is connected to the limiting post 22, and the horizontal section of the L - shaped plate 23 is located below the sleeve 21.

[0026] Specifically, as Figures 2 - 4As shown in the figure, the unlocking mechanism 3 is arranged below the conveyor belt 1. The unlocking mechanism 3 includes a first lifting rod 31 and a U-shaped pull rod 32 arranged at the top thereof. The U-shaped groove of the U-shaped pull rod 32 faces horizontally towards the L-shaped plate 23. The horizontal segments of two adjacent L-shaped plates 23 are both located in the U-shaped groove. The power source of the first lifting rod 31 can be driven by a cylinder or an oil cylinder, and is used to move the U-shaped pull rod 32 downward, and then move the two L-shaped plates 23 and the corresponding two limit posts 22 downward, so as to release the locking of the two limit posts 22 on the steel plate.

[0027] Specifically, as Figure 1 shown in the figure, the grinding table 4 is located outside the conveyor belt 1. The top surface of the grinding table 4 is flush with the top surface of the conveyor belt 1, and a channel is provided between the two, so as to translate the steel plate on the conveyor belt 1 to the grinding table 4 through the channel. Four circumferentially distributed avoidance holes 41 are provided on the surface of the grinding table 4. The avoidance holes 41 penetrate the grinding table 4 up and down. The diameter of the avoidance holes 41 is larger than the diameter of the notch of the steel plate. A grinding device 6 is provided below the grinding table 4, which is used to grind the four notches of the steel plate on the grinding table 4.

[0028] Specifically, the translation mechanism 5 is used to translate the unlocked steel plate onto the grinding table 4, and the notch of the steel plate corresponds to the avoidance hole 41. As Figure 1 shown in the figure, the translation mechanism 5 includes a linear travel component 51, a second lifting rod 52 and two circular plates 53. The linear travel component 51 is arranged on the support frame 54 and is erected above the conveyor belt 1 and the grinding table 4. The linear travel component 51 is connected to the second lifting rod 52, and the second lifting rod 52 is connected to the two circular plates 53. The connection line of the two circular plates 53 is perpendicular to the conveying direction of the conveyor belt 1. The linear travel component 51 is used to linearly move the second lifting rod 52 and the two circular plates 53. There are many ways to realize the linear travel component 51, such as by using a motor to drive a lead screw, or by using a cylinder or an oil cylinder to drive a telescopic rod. The power source of the second lifting rod 52 is driven by a cylinder or an oil cylinder. The second lifting rod 52 is used to move the two circular plates 53 downward so that the circular plates 53 are matched with the notches of the steel plate.

[0029] The usage method is as follows: First, place the steel plate on the conveyor belt 1 in advance, and the steel plate is located between two adjacent limit posts 22. The limit posts 22 play a role in limiting the steel plate to ensure that the steel plate will not move or rotate randomly. Use the conveyor belt 1 to convey the steel plates to the unlocking mechanism 3 in sequence. Taking the first steel plate as an example, when the first steel plate moves above the unlocking mechanism 3, the L-shaped plate 23 below the steel plate automatically moves into the U-shaped pull rod 32. First, use the second lifting rod 52 to lower the two circular plates 53 so that the circular plates 53 match the remaining notches of the steel plate. Then, use the first lifting rod 31 to lower the U-shaped pull rod 32, and further lower the two L-shaped plates 23 and the corresponding two limit posts 22 to release the locking of the two limit posts 22 on the first steel plate. The linear travel component 51 moves the second lifting rod 52 and the two circular plates 53 linearly towards the grinding table 4 until the notches of the steel plate correspond to the avoidance holes 41 one by one. During the translation of the steel plate, one function of the circular plate 53 is to promote the movement of the steel plate, and the other function is to ensure that the steel plate will not rotate randomly, so as to ensure that the notches of the steel plate correspond to the avoidance holes 41 one by one.

[0030] The specific implementation method of the translation mechanism 5 is as follows: As Figure 1 , Figure 6 shown, the translation mechanism 5 further includes a frame 55 and a first rack 56, a second rack 57, a gear 58 and a U-shaped plate 59 arranged in the frame 55. The frame 55 includes a baffle 554, a top plate 552, a partition plate 553 and two symmetric side plates 551. The top plate 552 covers the tops of the two side plates 551. The partition plate 553 is arranged between the two side plates 551. The baffle 554 covers one side of the two side plates 551. At the same height on the inner walls of the baffle 554 and the two side plates 551, there are bosses 555. Between the bosses 555 and the partition plate 553, there are two columns 556. The U-shaped plate 59 is horizontally arranged and is slidably matched with the two columns 556 up and down. A second spring 557 is arranged on the outer periphery of the column 556. The two ends of the second spring 557 are respectively connected to the partition plate 553 and the U-shaped plate 59. The two circular plates 53 are respectively arranged below the two branches of the U-shaped plate 59. The gear 58 is rotatably arranged between two vertical plates 581. The top of the vertical plate 581 is connected to the partition plate 553. The first rack 56 is vertically arranged and is fixedly connected to the inner wall of the U-shaped plate 59. At the position corresponding to the first rack 56 on the partition plate 553, there is a through groove 5531. The first rack 56 and the second rack 57 are arranged in parallel, and both the first rack 56 and the second rack 57 are engaged with the gear 58. The second lifting rod 52 is arranged on the bracket 521. The bracket 521 is connected to the frame 55. The bottom of the second lifting rod 52 is connected to the second rack 57. On the outside of the bottom of the second rack 57, there is a pressing block 571.

[0031] Instructions for use: The conveyor belt 1 conveys the steel plates to the top of the unlocking mechanism 3 in sequence, the second lifting rod 52 moves up the second rack 57, the second rack 57 shifts the gear 58, and then the first rack 56, the U-shaped plate 59 and the two circular plates 53 move downward as a whole, until the circular plate 53 matches the notch of the steel plate. In addition, please note that when the circular plate 53 matches the notch of the steel plate, the bottom surface of the first rack 56 should not contact the steel plate. The state at this time is as follows: Figure 8 Then the unlocking mechanism 3 releases the locking of the two limit columns 22 on the steel plate, and the state at this time is as Figure 9 As shown; the linear stroke assembly 51 moves the frame 55 and other components connected to the frame 55 as a whole toward the grinding table 4 until the gap in the steel plate corresponds to the avoidance hole 41 one by one. At this time, the state is as shown Figure 10 Then the second lifting rod 52 continues to move the second rack 57 downward, and the second rack 57 shifts the gear 58, thereby moving the first rack 56, the U-shaped plate 59 and the two circular plates 53 upward as a whole, until the circular plate 53 is out of the gap of the steel plate, and the pressing block 571 presses the steel plate on the grinding table 4. The state at this time is as shown in FIG. Figure 11 As shown, the four notches of the steel plate are then ground using a grinding device 6, and the function of the pressing block 571 is to prevent the steel plate from moving randomly during the grinding process.

[0032] like Figure 1 , Figure 7 As shown, the specific implementation of the grinding device 6 is as follows: it includes a housing 67 and four grinding rods 61, a first motor 62, a second motor 63, a cam 64, four sprocket wheels 65 and a chain 66 arranged in the housing 67. A support plate 68 is provided in the housing 67 for sliding up and down. The grinding rods 61 are located below the corresponding avoidance holes 41. The bottom of the grinding rods 61 is respectively provided with mounting columns 611. The bottom of the mounting columns 611 is rotatably connected to the support plate 68. The sprocket wheels 65 are coaxially arranged on the corresponding mounting columns 611. The chain 66 is sleeved on the four chain wheels. The outer periphery of the wheel 65, the first motor 62 is arranged at the bottom of the support plate 68, the output shaft of the first motor 62 is connected to one of the mounting columns 611, and is used to drive the mounting column 611, the second motor 63 is arranged on the bottom plate of the shell 67, the output shaft of the second motor 63 is connected to the cam 64, and is used to drive the second motor 63 arranged on the bottom plate of the shell 67, the output shaft of the second motor 63 is connected to the cam 64, and the side wall of the cam 64 is close to the bottom surface of the support plate 68, and the bottom of the support plate 68 is connected to the bottom plate of the shell 67 through a plurality of third springs 681.

[0033] The method of using the grinding device 6 is as follows: on the one hand, the first motor 62 drives one of the mounting columns 611, causing the four sprockets 65 and the four grinding rods 61 to rotate synchronously; on the other hand, the second motor 63 continuously drives the cam 64, which sometimes squeezes the support plate 68 upward, causing the first motor 62, the four sprockets 65, the chain 66 and the four grinding rods 61 to move upward as a whole, and sometimes the cam 64 releases the squeeze on the support plate 68, and then the support plate 68 moves downward under the action of the third spring 681, thereby causing the first motor 62, the four sprockets 65, the chain 66 and the four grinding rods 61 to move downward as a whole. In other words, the grinding rod 61 itself will rotate and move up and down with the support plate 68, thereby completing the grinding of the gap in the steel plate.

[0034] After the steel plate is polished, in order to facilitate the removal of the steel plate on the polishing table 4, the present embodiment adopts the following measures: Figure 1 As shown, the grinding device also includes a conveying table 7, which is docked with the grinding table 4, and the conveying directions of the conveying table 7 and the conveyor belt 1 are perpendicular. The linear travel component 51 extends above the conveying table 7, and the translation mechanism 5 is also used to translate the grinded steel plate onto the conveying table 7.

[0035] exist Figure 11 In this state, after the grinding of the steel plate gap is completed by the grinding equipment 6, the second lifting rod 52 moves up the second rack 57 and the pressure block 571, and the second rack 57 shifts the gear 58, thereby moving the first rack 56, the U-shaped plate 59 and the two circular plates 53 as a whole downward until the circular plate 53 matches the gap of the steel plate; the linear stroke assembly 51 moves the frame 55 and other components connected to the frame 55 as a whole toward the direction of the conveying platform 7 until the steel plate is translated onto the conveying platform 7.

[0036] The above embodiments are only used to illustrate the technical ideas and features of the present invention, and are not intended to be the only or limit the present invention.
