Technical Field

[0001] The invention relates to the technical field of mechanical processing equipment, in particular to an automatic feeding and grinding device for tubular parts. Background Art

[0002] In the fields of engineering machinery, automotive hydraulic systems, and pipe connection fittings, there are numerous tubular parts that require only single-end grinding (such as the sealed butt ends of hydraulic rigid pipes, the flanged ends of automotive transmission oil pipes, and the threaded ends of engineering machinery pipelines). The ground ends of these parts must meet stringent precision requirements: the end face must maintain excellent flatness to ensure a tight seal, the outer surface and the end face must maintain a high degree of perpendicularity to ensure assembly coaxiality, and the surface must have a certain degree of finish to reduce fluid resistance. The other end does not require grinding because it does not participate in the connection or has already passed preliminary processing (such as cutting and rolling) to meet the requirements.

[0003] In the prior art, after the clamping device clamps the part, it is necessary to translate the clamped part before grinding the part. The part cannot be ground in situ, which will inevitably reduce the grinding accuracy.

[0004] Therefore, it is necessary to develop and design an automatic feeding and grinding device for tubular parts. Improving the grinding accuracy of tubular parts is a technical problem that currently needs to be solved urgently by those skilled in the art. Summary of the Invention

DETAILED DESCRIPTION

[0026] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0027] The purpose of the present invention is to provide an automatic feeding and grinding device for tubular parts, so as to improve the grinding accuracy of the tubular parts.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0029] refer to Figures 1-4 The automatic feeding and grinding device for tubular parts disclosed in the embodiment of the present invention at least includes a conveying device for conveying tubular parts 3. The conveying end of the conveying device is connected to the clamping device to convey the tubular parts 3 to the clamping device. A grinding device for grinding the tubular parts 3 is provided above the clamping device. The grinding device includes a telescopic frame, on which a grinder 5 is provided. The grinder 5 can move up and down with the telescopic frame. The telescopic frame is provided with a belt drive motor 6 for driving a grinding head provided on the grinder 5 to rotate. The grinding head is arranged directly opposite the tubular part 3. By setting the grinding head directly opposite the tubular part 3, after the clamping device clamps the tubular part 3, there is no need to move the tubular part 3 to the grinding head. The tubular part 3 can be ground in the clamping position, thereby ensuring the grinding accuracy of the tubular part 3.

[0030] refer to Figure 1 In one embodiment, the conveying device includes a frame 16, a driving device is provided inside the frame 16, and the output end of the driving device is connected to the rotating disc 2, the driving device can drive the rotating disc 2 to rotate, and an annular baffle 1 is provided on the circumference of the rotating disc 2, the annular baffle 1 can limit the tubular part 3, and a conveying channel 15 is provided on the edge of the annular baffle 1. The conveying channel 15 passes through the annular baffle 1 and extends a distance into the interior of the annular baffle 1. The conveying channel 15 is connected to the clamping device. When the driving device drives the rotating disc 2 to rotate, the tubular part 3 rotates with it on the rotating disc 2, moves toward the edge under the action of centrifugal force, and is restricted in the annular area after contacting the annular baffle 1. It continues to move with the rotating disc 2 to the conveying channel 15, and is then conveyed to the clamping device through the conveying channel 15.

[0031] It should be noted that a conveyor belt is provided at the bottom of the conveying channel 15 so as to convey the tubular parts 3 through the conveyor belt.

[0032] refer to Figure 1 As a preferred method, an isolation baffle is provided on the conveying channel 15 for isolating adjacent tubular parts. The isolation baffle can be extended and retracted in the conveying direction perpendicular to the conveying channel 15. By setting the isolation baffle, after the tubular parts 3 are conveyed to the conveying channel 15, the isolation baffle will isolate the tubular parts 3 close to the clamping device from other tubular neighbors, avoiding the problem that multiple tubular parts 3 are too closely spaced and the tubular parts 3 cannot be accurately clamped.

[0033] refer to Figure 1 As an embodiment, a guide plate 17 is provided at one end of the conveying channel 15 close to the clamping device. The guide plate 17 is parallel to the conveying direction of the conveying channel 15 and is arranged close to the center of the rotating disk 2. The conveying channel 15 is laterally provided with bolts that pass through the conveying channel 15 and the guide plate 17 at the same time. Adjustment nuts are provided on both sides of the guide plate 17. The guide plate 17 can guide the tubular part 3 and guide the tubular part 3 to a position facing the clamping device. By setting the bolts and adjusting nuts, when the size of the tubular part 3 changes, the guide plate 17 can be adjusted to change the width of the conveying channel 15 to ensure the guiding effect on the tubular part 3.

[0034] refer to Figure 1 As a preferred method, a guide plate 4 connected to the conveying channel 15 is provided inside the annular baffle 1. By providing the guide plate 4, the tubular part 3 conveyed to the edge of the annular baffle 1 by centrifugal force can be guided so that the tubular part 3 is conveyed to the inside of the conveying channel 15.

[0035] refer to Figure 1-Figure 3 As a preferred embodiment, the driving device includes a transmission motor 23 arranged inside the frame 16, and the output end of the transmission motor 23 is connected to the reducer 22, and the output end of the reducer 22 is provided with an adapter flange 24, and the end of the adapter flange 24 away from the reducer 22 is connected to the rotating disc 2 through a bottom plate 26, and a shaft ring 25 is sleeved on the adapter flange 24 where it fits the bottom plate 26. When the transmission motor 23 drives the reducer 22 to operate, the power is transmitted to the shaft ring 25 through the adapter flange 24, and then the shaft ring 25 drives the rotating disc 2 to rotate around the central axis, thereby realizing the rotation function of the rotating disc 2, wherein the annular baffle 1 is connected to the base 27, and the base 26 is fixed to the base 27, integrating the shaft ring 25 into a whole, enhancing the structural rigidity, and ensuring the stable operation of the shaft ring 25 and the entire transmission system. A motor bracket is provided at the bottom of the transmission motor 23 and the reducer 22.

[0036] refer to Figure 1As a preferred embodiment, the clamping device includes a supporting platform, on which a telescopic motor 9 and a propulsion mechanism 8 are provided, the output end of the telescopic motor 9 is connected to the propulsion mechanism 8, and a clamping portion is provided at one end of the propulsion mechanism 8 away from the telescopic motor 9, the clamping portion includes a first clamping plate 19 and a second clamping plate 20 respectively hinged to the two ends of the propulsion mechanism 8, a spring 7 is provided between the first clamping plate 19 and the second clamping plate 20, and a first limiting plate 18 and a second limiting plate are respectively provided on the supporting platform, and a first annular clamping plate 21 and a second annular clamping plate 14 are provided at the ends of the first clamping plate 19 and the second clamping plate 20 away from the propulsion mechanism 8. When the tubular part 3 needs to be clamped, the telescopic motor 9 drives the first clamping plate 19 and the second clamping plate 20 to move toward the end close to the conveying channel 15. At this time, since there is no first limiting plate 1 8 and the second limiting plate, under the action of the restoring force of the spring 7, the first clamping plate 19 and the second clamping plate 20 move away from each other, thereby moving the first annular clamping plate 21 and the second annular clamping plate 14 away from each other, and the openings of the first annular clamping plate 21 and the second annular clamping plate 14 are arranged opposite to the outlet of the tubular part 3 of the conveying channel 15, and the tubular part 3 of the conveying channel 15 is conveyed between the first annular clamping plate 21 and the second annular clamping plate 14, and the telescopic motor 9 drives the first clamping plate 19 and the second clamping plate 20 to retract. Under the limitation of the first limiting plate 18 and the second limiting plate, the spring 7 is compressed to make the first clamping plate 19 and the second clamping plate 20 approach each other, thereby closing the first annular clamping plate 21 and the second annular clamping plate 14 to achieve clamping of the tubular part 3, and when the first annular clamping plate 21 and the second annular clamping plate 14 are closed, the tubular part 3 is facing the grinding head on the grinder 5.

[0037] refer to Figure 1 and Figure 4 As an implementation method, a screw rod 10 is provided at the bottom of the supporting platform, and the first limit plate 18 and the second limit plate pass through the supporting platform and are threadedly connected to the screw rod 10. The screw rod 10 can adjust the distance between the first limit plate 18 and the second limit plate. By setting the screw rod 10, the distance between the first limit plate 18 and the second limit plate can be adjusted to adapt to tubular parts 3 of different sizes.

[0038] It should be noted that a screw drive motor is provided at the end of the screw 10 to drive the screw 10 to rotate, so as to automatically adjust the distance between the first limiting plate 18 and the second limiting plate.

[0039] refer to Figure 1As an implementation method, a telescopic baffle 11 is provided at the bottom of the first annular clamping plate 21 and the second annular clamping plate 14. The telescopic baffle 11 is connected to the push rod telescopic motor 28 provided at the bottom of the supporting platform. A collecting device 13 for collecting tubular parts is provided at the bottom of the telescopic baffle 11. After the grinding of the tubular parts 3 is completed, the push rod telescopic motor 28 drives the telescopic baffle 11 to move. The tubular parts 3 set above the telescopic baffle 11 fall into the collecting device 13 due to lack of support, thereby completing the collection of the processed tubular parts 3.

[0040] It should be noted that when the tubular component 3 is conveyed to the clamping device through the conveying channel 15 , it is supported by the telescopic baffle 11 .

[0041] refer to Figure 1 As an embodiment, a support platform 12 for supporting the collecting device 13 is provided below the supporting platform.

[0042] refer to Figure 1 As an embodiment, a gravity sensor is provided on the telescopic baffle 11. The gravity sensor on the telescopic baffle 11 senses the weight and stops the rotating disc 2. At this time, the telescopic motor 9 pulls the propulsion mechanism 8 backward, so that the first annular clamping plate 21 and the second annular clamping plate 14 clamp the tubular part 3. The belt drive motor 6 drives the grinder 5 to rotate, and moves up and down through the lifting frame to achieve precise grinding of the tubular part 3. After the grinding is completed, the grinder 5 is raised, and the telescopic motor 9 simultaneously pushes the propulsion mechanism 8 forward to release the first annular clamping plate 21 and the second annular clamping plate 14 from the tubular part 3, and the telescopic baffle 11 is also moved backward by the push rod telescopic motor 28, so that the tubular part 3 falls into the collecting device 13 below. After the tubular part 3 falls, the push rod telescopic motor 28 pushes the telescopic baffle 11 forward, and the rotating disc 2 starts working again.

[0043] It should be noted that it will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above and that the present invention can be implemented in other specific forms without departing from the spirit or essential characteristics of the present invention. Therefore, the embodiments should be considered in all respects as illustrative and non-restrictive, and the scope of the present invention is defined by the appended claims, not the foregoing description, and it is intended that all variations within the meaning and range of equivalents of the claims be encompassed therein. Any reference signs in the claims should not be construed as limiting the claim to which they relate.
