Technical Field
[0001] This utility model relates to the field of conveying equipment technology, and in particular to a conveying device. Background Technology
[0002] A conveying device is a mechanical structure that continuously transports workpieces along a defined route from a loading station to a unloading station, where they are then processed. Currently, to improve the processing accuracy of workpieces (dimensional accuracy, shape accuracy, and surface quality), it is necessary to improve the accuracy of the conveying device (i.e., design the entire conveying device to be high-precision), which increases the overall production cost of the conveying device. Utility Model Content
[0003] In response to the shortcomings of the existing production technology, the applicant provides a conveying device that, through improvements to the structure of the conveying device, can ensure the workpiece processing accuracy while reducing the production cost of the conveying device.
[0004] The technical solution adopted in this utility model is as follows:
[0005] A conveying device includes: a worktable, a linear guide mechanism, a drive mechanism, and a base. The worktable is used to carry and convey workpieces. The linear guide mechanism includes: a linear guide section and a slider. The linear guide section is slidably connected to the linear guide section. The slider is connected to the worktable. The drive mechanism includes: a first drive member, a first roller, and a rack. The first drive member is connected to the worktable. The drive end of the first drive member is connected to the first roller. The first roller meshes with the rack. The linear guide section and the rack are both mounted on the base. The base includes: a first base, a second base, and a third base connected in sequence. The second base is parallel to a horizontal plane. The plane accuracy of the second base near the linear guide section and the rack is greater than the plane accuracy of the first base and the third base near the linear guide section and the rack.
[0006] Therefore, only the second base is designed to be high-precision, while the first and third bases are not designed to be high-precision. Compared with the design of the entire conveying device to be high-precision, this method has a simple structure and is easy to operate. Since only the second base is designed to be high-precision, the workpiece processing accuracy can be ensured while reducing the production cost of the entire conveying device.
[0007] As a further improvement to the above technical solution: the support part, the drive unit, and the turntable, the slider and the first drive component are all connected to the support part through the fixing part, the drive unit is connected to the support part, the drive end of the drive unit is connected to the turntable, and the turntable is rotatably connected to the support part; the linear guide mechanism and the drive mechanism are used together to drive the support part to move along the conveying direction of the workpiece, and the drive unit is used to drive the turntable to rotate along its axis.
[0008] As a further improvement to the above technical solution: two base portions are provided, and the two base portions are arranged opposite to each other.
[0009] As a further improvement to the above technical solution: the linear guide mechanism corresponds one-to-one with the base portion.
[0010] As a further improvement to the above technical solution: the linear guide section includes: a first linear guide, a second linear guide, and a third linear guide connected in sequence.
[0011] As a further improvement to the above technical solution: the connection point between the first linear guide rail and the second linear guide rail is position A, and the connection point between the second linear guide rail and the third linear guide rail is position B; the straight line where the two positions A are located is the first straight line, and the straight line where the two positions B are located is the second straight line. The angle between the first straight line and the workpiece conveying direction is α, and the angle between the second straight line and the workpiece conveying direction is β, where 0° < α < 90° and 0° < β < 90°. Therefore, by using the design method of 0° < α < 90° and 0° < β < 90°, the first linear guide rail, the second linear guide rail, and the third linear guide rail of the two linear guide rail sections are relatively staggered, thereby preventing the slider from simultaneously moving to the gap between the first and second linear guide rails and the gap between the second and third linear guide rails, thus reducing the vibration and noise generated when the worktable moves.
[0012] As a further improvement to the above technical solution, it also includes: a plurality of fourth bases, which are equally spaced along the conveying direction of the workpiece, and the fourth bases are connected to the base portion. Thus, the entire conveying device can be placed on the ground or mounted on other mechanical equipment via the fourth bases.
[0013] As a further improvement to the above technical solution, it also includes: the housing part, the housing part comprising: a first housing and a second housing, the two ends of the first housing being connected to one end of the two base parts respectively, the two ends of the two second housings being connected to the other end of the two base parts respectively, and the fixing part penetrating the second housing and slidably connected to the second housing.
[0014] As a further improvement to the above technical solution: a receiving space is formed between the first housing, the second housing, and the two base portions, and the linear guide mechanism and the drive mechanism are both located within this receiving space. Therefore, the linear guide mechanism and the drive mechanism are not in contact with the external environment, ensuring that they are not contaminated by dust from the external environment. This reduces vibration and noise generated during table movement and extends the service life of the linear guide mechanism and the drive mechanism.
[0015] As a further improvement to the above technical solution: the drive unit includes a second drive member, a second roller, and a gear ring. The second drive member is connected to the support portion, the drive end of the second drive member is connected to the second roller, the second roller meshes with the gear ring, and the gear ring is connected to the turntable. Thus, activating the second drive member drives the second roller to rotate, and with the cooperation of the gear ring, the turntable rotates along its axis.
[0016] The beneficial effects of this utility model are as follows:
[0017] By designing the second base to be of high precision, while the first and third bases are not designed to be of high precision, this method is simpler in structure and easier to operate compared to the design of the entire conveying device to be of high precision. Since only the second base is designed to be of high precision, the workpiece processing accuracy can be ensured while reducing the production cost of the entire conveying device.
[0018] This utility model also has the following advantages:
[0019] 1. This utility model uses a design of 0°<α<90° and 0°<β<90° to make the first linear guide rail, the second linear guide rail, and the third linear guide rail of the two linear guide rails relatively staggered. This prevents the slider from moving to the gap between the first and second linear guide rails and the gap between the second and third linear guide rails at the same time, thereby reducing the vibration and noise generated when the worktable moves.
[0020] 2. Neither the linear guide mechanism nor the drive mechanism of this utility model comes into contact with the external environment, ensuring that the linear guide mechanism and the drive mechanism will not be contaminated with dust from the external environment. This reduces the vibration and noise generated when the worktable moves and increases the service life of the linear guide mechanism and the drive mechanism. Attached Figure Description

[0043] The specific embodiments of this utility model are described below with reference to the accompanying drawings.
[0044] like Figures 1 to 11 The diagram shows the preferred embodiment of this utility model. The conveying device of this embodiment includes: a worktable 1, a linear guide mechanism 2, a drive mechanism 3, and a base 4. The worktable 1 is used to carry and convey workpieces. The linear guide mechanism 2 includes: a linear guide section 201 and a slider 202. The linear guide section 201 is slidably connected to the worktable 1, and the slider 202 is connected to the worktable 1. The drive mechanism 3 includes: a first drive member 301, a first roller 302, and a rack 303. The first drive member 301 is connected to the worktable 1, and the first drive member 302... The drive end of 1 is connected to the first roller 302, and the first roller 302 meshes with the rack 303. The linear guide section 201 and the rack 303 are both installed on the base section 4. The base section 4 includes a first base 401, a second base 402 and a third base 403 connected in sequence. The second base 402 is parallel to the horizontal plane. The plane accuracy of the second base 402 near the linear guide section 201 and the rack 303 is greater than the plane accuracy of the first base 401 and the third base 403 near the linear guide section 201 and the rack 303. Therefore, only the second base 402 is designed to be of high precision (i.e., the plane of the second base 402 near the linear guide 201 and rack 303 is kept horizontal, and the plane of the second base 402 near the linear guide 201 and rack 303 has high precision), while the first base 401 and the third base 403 are not designed to be of high precision. Compared with the high precision design of the entire conveying device, this method is simple in structure and easy to operate. Since only the second base 402 is designed to be of high precision, the workpiece processing accuracy can be ensured while reducing the production cost of the entire conveying device.
[0045] In other words, to ensure the machining accuracy of the workpiece, it is necessary to ensure the high-precision design of the workpiece machining area. Existing technology uses a high-precision design for the entire conveying device, which can ensure the machining accuracy of the workpiece. However, designing the entire conveying device with high precision will increase the production cost. In this solution, only the second base 402 is designed with high precision (i.e., the high-precision design of the machining area). In this way, the machining accuracy of the workpiece can be ensured while reducing the production cost of the entire conveying device.
[0046] Specifically, the first drive unit 301 is activated, which drives the first roller 302 to rotate. With the cooperation of the rack 303, the worktable 1 moves along the conveying direction of the workpiece.
[0047] For example, the first driving component 301 is a motor.
[0048] In this embodiment, the workbench 1 includes a support 101, a drive unit 102, and a turntable 103. The slider 202 and the first drive member 301 are both connected to the support 101 through a fixing part 104. The drive unit 102 is connected to the support 101, and the drive end of the drive unit 102 is connected to the turntable 103. The turntable 103 is rotatably connected to the support 101. The drive unit 102 includes a second drive member 1021, a second roller 1022, and a gear ring 1023. The second drive member 1021 is connected to the support 101, and the drive end of the second drive member 1021 is connected to the second roller 1022. The second roller 1022 meshes with the gear ring 1023, and the gear ring 1023 is connected to the turntable 103. Therefore, the second drive unit 1021 is activated, which drives the second roller 1022 to rotate, and with the cooperation of the gear ring 1023, the turntable 103 rotates along its axis.
[0049] For example, the second drive component 1021 uses a motor.
[0050] In this embodiment, two base parts 4 are provided, and the two base parts 4 are arranged opposite to each other; the linear guide mechanism 2 corresponds to the base parts 4 one by one; the linear guide part 201 includes: a first linear guide 2011, a second linear guide 2012 and a third linear guide 2013 connected in sequence; the connection point between the first linear guide 2011 and the second linear guide 2012 is position A, and the connection point between the second linear guide 2012 and the third linear guide 2013 is position B; the straight line where the two positions A are located is the first straight line, the straight line where the two positions B are located is the second straight line, the angle between the first straight line and the workpiece conveying direction is α, the angle between the second straight line and the workpiece conveying direction is β, 0°<α<90°, 0°<β<90°. Therefore, by using the design method of 0°<α<90° and 0°<β<90°, the first linear guide 2011 of the two linear guide sections 201 is staggered relative to each other, the second linear guide 2012 is staggered relative to each other, and the third linear guide 2013 is staggered relative to each other. This prevents the slider 202 from moving to the gap between the first linear guide 2011 and the second linear guide 2012, and the gap between the second linear guide 2012 and the third linear guide 2013 at the same time, thereby reducing the vibration and noise generated when the worktable 1 moves.
[0051] In this embodiment, the device further includes a plurality of fourth bases 5, which are evenly spaced along the conveying direction of the workpiece and are connected to the base portion 4. Thus, the entire conveying device can be placed on the ground or mounted on other mechanical equipment via the fourth bases 5.
[0052] In this embodiment, the system further includes a housing portion 6, which comprises a first housing 601 and a second housing 602. The two ends of the first housing 601 are respectively connected to one end of each of the two base portions 4, and the two ends of the two second housings 602 are respectively connected to the other ends of each of the two base portions 4. A fixing portion 104 passes through the second housing 602 and is slidably connected to it. A receiving space is formed between the first housing 601, the second housing 602, and the two base portions 4, and the linear guide mechanism 2 and the drive mechanism 3 are both located within this receiving space. Therefore, the linear guide mechanism 2 and the drive mechanism 3 are not in contact with the external environment, ensuring that they are not contaminated by dust from the external environment. This reduces vibration and noise generated when the worktable 1 moves and improves the service life of the linear guide mechanism 2 and the drive mechanism 3.
[0053] The workpiece conveying process of this utility model is as follows: First, the workbench 1 is placed in the loading area of the entire conveying device, and the workpiece to be conveyed is placed on the workbench 1; then, the first drive unit 301 is started, and with the cooperation of the first roller 302 and the rack 303, the workpiece is conveyed from the loading area to the processing area along with the workbench 1 through the linear guide mechanism 2; then, through the cooperation of the linear guide mechanism 2, the drive mechanism 3, the drive unit 102 and the processing part (not shown in the figure), the workpiece is processed in the processing area; finally, the first drive unit 301 is started, and with the cooperation of the first roller 302 and the rack 303, the workpiece is conveyed from the processing area to the unloading area along with the workbench 1 through the linear guide mechanism 2, thus completing the conveying of the workpiece from the loading area to the unloading area.
[0054] In summary, this utility model only designs the second base 402 to be of high precision, while the first base 401 and the third base 403 are not designed to be of high precision. Compared with the design method of high precision for the entire conveying device, this method has a simple structure and is easy to operate. Since only the second base 402 is designed to be of high precision, the workpiece processing accuracy can be ensured while reducing the production cost of the entire conveying device.
