Description

Technical Field

[0001] The utility model relates to the field of parts processing, in particular to an automobile parts positioning device. Background Art

[0002] Auto parts are the various units that constitute the overall auto parts processing and the products that serve the auto parts processing. Traditional auto parts can be roughly divided into seven categories, namely engine, transmission system, steering system, braking system, running system, body accessories and electronic appliances.

[0003] Sometimes, pipe fittings or shaft workpieces are needed in automobile parts, and cutting, welding and other operations are required on the pipe fittings or shaft workpieces. When processing traditional pipe fittings or shaft workpieces, clamping mechanisms are often used to position both ends. However, the base of the clamping mechanism is mostly fixed, that is, the clamping mechanism is fixed at the lower end of the processing mechanism, and the space is small. Although the processing mechanism can be moved using a robotic arm to expand the loading and unloading space of the pipe fittings or shaft workpieces, in actual operation, the placement of the pipe fittings or shaft workpieces is still dangerous due to the risk of failure or misoperation of the robotic arm. In view of the existing problems, an automobile parts positioning device is proposed. Utility Model Content

[0004] The utility model aims to solve the disadvantage of certain danger in the placement and positioning of pipe fittings or shaft-like workpieces in the prior art, and proposes an automobile parts positioning device.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A positioning device for automobile parts is designed, including two bases and a positioning mechanism, wherein the positioning mechanism is installed on the upper ends of the two bases, and the positioning mechanism includes an arc-shaped base plate, two end seats, and a bidirectional screw. The arc-shaped base plate is movably placed on the upper ends of the two bases, and the two end seats are fixedly installed at the two ends of the upper surface of the arc-shaped base plate. The two ends of the bidirectional screw are rotatably penetrated and installed on the two end seats, and the two ends of the bidirectional screw are respectively threadedly sleeved with a moving seat, and an auxiliary deflection mechanism is installed on the two bases and the lower surface of the arc-shaped base plate.

[0007] Preferably, a clamping piece is rotatably mounted on the inner side of the movable seat at both ends, a first motor is fixedly mounted on the outer side of the movable seat, and an output shaft of the first motor is fixedly connected to the clamping piece.

[0008] Preferably, a rubber pad is attached to the outer side of the clamping member.

[0009] Preferably, a slide groove is provided on the arc-shaped bottom plate, and a slide rack is fixedly installed under the movable seat.

[0010] Preferably, the auxiliary deflection mechanism comprises a rotating shaft and two gears, both ends of the rotating shaft are rotatably installed on the two bases, the two gears are fixedly installed at both ends of the rotating shaft, and a gear plate is fixedly installed on the lower surface of the arc bottom plate corresponding to the two gears.

[0011] Preferably, a limiting frame is fixedly installed in the middle of the lower surface of the arc-shaped bottom plate, and the limiting frame is sleeved on the rotating shaft.

[0012] Preferably, the lower side of the limiting frame is arranged in an arc shape corresponding to the lower surface of the arc-shaped bottom plate, and the lower inner wall of the limiting frame is in contact with the rotating shaft.

[0013] The utility model provides an automobile parts positioning device, which has the following beneficial effects:

[0014] 1. Through the threaded transmission cooperation between the bidirectional screw and the moving seat in the positioning mechanism, when the bidirectional screw rotates, it can drive the two moving seats to move closer or farther synchronously, so that pipes or shaft parts of different lengths can be clamped and positioned through the clamping piece, which has stronger adaptability, and the first motor can drive the pipe or shaft parts and the clamping piece to rotate, which is convenient for processing the outer circular wall of the pipe or shaft parts without dead angles. At the same time, the slide under the moving seat slides in the slide groove, which can effectively prevent the moving seat from rotating with the bidirectional screw during the movement, which is more stable and reliable;

[0015] 2. The arc-shaped bottom plate is tilted at multiple angles on the two bases. When the positioning mechanism tilts to both sides as a whole, the upper end of the mobile seat and the protrusion of the clamping piece can greatly facilitate the supply and placement of pipe fittings or shaft parts, as well as the unloading of pipe fittings or shaft parts after processing. The rotation of the shaft and the meshing transmission between the gear and the toothed plate can drive the arc-shaped bottom plate to deflect within a certain angle. At the same time, the setting of the limit frame can always ensure that the lower surface of the arc-shaped bottom plate fits the upper end of the base to ensure safety and reliability.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Example 1

[0023] Reference Figure 1-4 A positioning device for automobile parts includes two bases 1 and a positioning mechanism 2. The positioning mechanism 2 is installed on the upper ends of the two bases 1. The positioning mechanism 2 includes an arc-shaped bottom plate 21, two end seats 22, and a bidirectional screw 23. The upper ends of the two bases 1 are provided with arc-shaped grooves corresponding to the lower surfaces of the arc-shaped bottom plates 21, so as to ensure the deflection and inclination of the positioning mechanism 2 as a whole on the upper ends of the two bases 1, which is convenient for the placement and unloading of pipe fittings or shaft parts. The arc-shaped bottom plate 21 is movably placed on the upper ends of the two bases 1, and the two end seats 22 are fixedly installed at both ends of the upper surface of the arc-shaped bottom plates 21. The two ends of the bidirectional screw 23 are rotatably penetrated and installed on the two end seats 22. Both ends of the bidirectional screw 23 are provided with external threads. A driving motor is fixedly installed on the outer side of one of the end seats 22. The output shaft of the driving motor is fixedly connected to the bidirectional screw 23, and the two ends of the bidirectional screw 23 are respectively threadedly connected. There is a movable seat 24, and the inner sides of the movable seats 24 at both ends are rotatably installed with clamping members 25, and the outer sides of the movable seats 24 are fixedly installed with a first motor 26, and the output shaft of the first motor 26 is fixedly connected to the clamping member 25, and a rubber pad is attached to the outer side of the clamping member 25. The rubber pad can isolate the end of the pipe or shaft part from direct contact with the clamping member 25, thereby reducing damage and wear to the end of the pipe or shaft part. Through the threaded transmission cooperation of the bidirectional screw 23 and the movable seat 24 in the positioning mechanism 2, when the bidirectional screw 23 rotates, it can drive the two movable seats 24 to approach or move away synchronously, so that pipes or shaft parts of different lengths can be clamped and positioned by the clamping member 25, which has stronger adaptability, and the first motor 26 can drive the pipe or shaft part and the clamping member 25 to rotate, so as to facilitate the processing of the outer cylindrical wall of the pipe or shaft part without dead angle.

[0024] A slide groove 27 is provided on the arc bottom plate 21, and a slide 28 is fixedly installed under the moving seat 24. The slide 28 slides in the slide groove 27. At the same time, the slide 28 under the moving seat 24 slides in the slide groove 27, which can effectively prevent the moving seat 24 from rotating with the bidirectional screw 23 during movement, making it more stable and reliable.

[0025] Example 2

[0026] According to Example 1, the positioning mechanism 2 in Example 1 is placed on two bases 1 through the arc bottom plate 21, and has strong mobility, but the deflection angle is not easy to control. Figure 1-4 As another preferred embodiment of the utility model, based on embodiment 1, it further includes an auxiliary deflection mechanism 3;

[0027] The auxiliary deflection mechanism 3 is installed on the two bases 1 and the lower surface of the arc-shaped bottom plate 21. The auxiliary deflection mechanism 3 includes a rotating shaft 31 and two gears 32. The two ends of the rotating shaft 31 are rotatably installed on the two bases 1. The two gears 32 are fixedly installed at the two ends of the rotating shaft 31. A tooth plate 33 is fixedly installed on the lower surface of the arc-shaped bottom plate 21 corresponding to the two gears 32. The gears 32 and the tooth plates 33 are meshed and transmitted. The arc-shaped bottom plate 21 is tilted at multiple angles on the two bases 1. When the positioning mechanism 2 is tilted to both sides as a whole, the upper end of the moving seat 24 and the protrusion of the clamping member 25 can greatly facilitate the supply and placement of pipe fittings or shaft parts, and the unloading of pipe fittings or shaft parts after processing. The rotation of the rotating shaft 31 and the meshing transmission cooperation between the gear 32 and the tooth plate 33 can drive the arc-shaped bottom plate 21 to deflect within a certain angle.

[0028] A limiting frame 34 is fixedly installed in the middle of the lower surface of the arc-shaped bottom plate 21, and the limiting frame 34 is sleeved on the rotating shaft 31. A second motor is fixedly installed on the outer side of the base 1, and the output shaft of the second motor is fixedly connected to the rotating shaft 31. The lower side of the limiting frame 34 corresponds to the arc-shaped setting of the lower surface of the arc-shaped bottom plate 21, and the lower inner wall of the limiting frame 34 fits with the rotating shaft 31. At the same time, the setting of the limiting frame 34 can always ensure that the lower surface of the arc-shaped bottom plate 21 fits with the upper end of the base 1, ensuring safety and reliability.

[0029] Working principle: When in use, first control the second motor to drive the rotating shaft 31 to rotate, and drive the arc bottom plate 21 to deflect through the meshing transmission of the gear 32 and the toothed plate 33, so that the pipe fittings or shaft parts to be processed are placed between the two clamping parts 25 through the protrusion of the upper end of the moving seat 24 and the clamping part 25, and control the driving motor on the outer side of the end seat 22 to start, and the output shaft of the driving motor drives the bidirectional screw 23 to rotate, and through the threaded transmission cooperation of the bidirectional screw 23 and the moving seat 24 in the positioning mechanism 2, when the bidirectional screw 23 rotates, it can drive the two moving seats 24 to approach synchronously, so that the pipe fittings or shaft parts of different lengths can be clamped and positioned by the clamping part 25, and then the arc bottom plate 21 deflects to make the moving seat 24 erect, and the pipe fittings or shaft parts can be processed by the processing mechanism. After the processing is completed, the arc bottom plate 21 is controlled to deflect in the opposite direction, and the rotation of the bidirectional screw 23 drives the two moving seats 24 to move away synchronously, releasing the pipe fittings or shaft parts after processing.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
