Description

Technical Field

[0001] The present application relates to the technical field of shaft detection, and in particular to an external circle runout detection device. Background Art

[0002] Circular runout refers to the difference between the maximum and minimum readings measured by a fixed indicator in a given direction when the measured element rotates around the reference axis for one circle. The circular runout tolerance is the maximum allowable change in the indicator value when the measured element rotates around the reference axis for one circle at a fixed reference point (there is no axial displacement between the part and the measuring instrument).

[0003] When performing circular runout detection on each shaft, the circular runout detection device in traditional technology requires employees to manually clamp and manually drive the detection instrument to move and rotate along the axial direction of the shaft. This method is relatively inefficient and cannot guarantee detection accuracy.

[0004] In order to solve the above problems, the present application discloses an external circle runout detection device.

[0024] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0025] In the description of the present application, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limitations on the present application.

[0026] Example

[0027] In order to solve the problem of manually detecting the outer circle of the shaft in the prior art, Figure 1-Figure 3 As shown, the present application discloses an outer circle runout detection device, comprising:

[0028] The belt conveyor line 10 is provided with a plurality of supporting jigs 20 for placing shafts. In a specific implementation, the shafts are placed on the supporting jigs and gradually move forward under the drive of the belt conveyor line.

[0029] The rotating clamping mechanism 30 includes two telescopic drive components 31 disposed on both sides of the middle of the belt conveyor line, an active rotating shaft seat 32 and a driven rotating shaft seat 33 respectively disposed on the two telescopic drive components, and two tops 34 respectively disposed on the active rotating shaft seat and the driven rotating shaft seat. When the supporting fixture reaches the middle of the belt conveyor line, the two telescopic drive components synchronously drive the active rotating shaft seat and the driven rotating shaft seat to extend so that the two tops support the shaft on the supporting fixture;

[0030] The beating detection mechanism 40 includes a first gantry 41 erected above the belt conveyor line, a transverse drive assembly 42 arranged on the first gantry crossbeam, a first lifting drive assembly 43 connected to the transverse drive assembly, an L-shaped plate 44 connected to the first lifting drive assembly, and a contact probe 45 arranged on the L-shaped plate. Two top ends on the above-mentioned active rotating shaft seat and driven rotating shaft seat abut against the shaft member. The transverse drive assembly drives the first lifting drive assembly to the initial detection position, and then drives the contact probe to descend through the first lifting drive assembly to make it contact with the shaft member, and the shaft member is rotated through the active rotating shaft seat and the driven rotating shaft seat. In this process, the transverse drive assembly drives the first lifting drive assembly to move along the axial direction of the shaft member, so that the entire shaft member can be fully tested for beating;

[0031] The sorting and unloading mechanism 50 includes a second door frame 51 erected above the conveying end of the belt conveyor line and extending to both sides of the outside, two lateral moving components 52 arranged on the second truss crossbeam, two second lifting and driving components 53 respectively connected to the two lateral moving components, two grabbing manipulators 54 respectively connected to the two second lifting and driving components, and a qualified product recovery box 55 and an unqualified product recovery box 56 respectively arranged on both sides of the conveying end of the belt conveyor line. When the supporting fixture reaches the conveying end of the belt conveyor line, if the contact probe detects that the vibration of the shaft is qualified, the corresponding lateral moving component will drive the second lifting and driving component to move above the belt conveyor line. After it is in place, the second lifting and driving component drives the grabbing manipulator to descend so that the grabbing manipulator grabs the detected shaft. After that, the corresponding lateral moving component brings the second lifting and driving component to the top of the qualified product recovery box and puts the grabbed shaft into the qualified product recovery box. Otherwise, it will not be repeated. The working principle is the same.

[0032] The supporting jig of the present application includes a jig plate 21 arranged on the belt conveyor line, two support blocks 22 arranged on both sides of the jig plate and a V-shaped groove 221 opened above the two support blocks. In specific implementation, the operator only needs to place the shaft to be inspected in the V-shaped grooves of the two support blocks.

[0033] In order to ensure that the supporting carrier reaches the detection position accurately, the present application is provided with a shooting sensor on the opposite side of the shaft rotating shaft seat and the driven rotating shaft seat. When the shooting sensor cannot detect the supporting fixture, the belt conveyor line moves normally. On the contrary, if the shooting sensor detects the supporting fixture, the belt conveyor line will stop running. At this time, it means that the supporting carrier reaches the set detection position, and the next step can be carried out.

[0034] Specifically, the first lateral drive assembly, the first lifting drive assembly, the second lifting drive assembly and the two telescopic drive assemblies of the present application are all servo screw modules. The servo screw module has high precision and can accurately detect the outer circle runout of the shaft.

[0035] In this embodiment, two linear slide rails 521 are arranged side by side on one side of the crossbeam of the second gantry, and a linear rack 522 is arranged between the two linear slide rails. The lateral moving assembly includes a slide 523 slidably arranged on the two linear slide rails, a servo motor 524 arranged on the slide and having its output shaft passing through the slide, and a gear 525 installed on the output shaft of the servo motor and meshingly connected with the linear rack. According to the detection result of the contact probe, the corresponding servo motor drives the gear to rotate and cooperate with the rack, so that the slide can slide on the two linear slide rails until it reaches directly above the belt conveyor line.

[0036] In this embodiment, the material grabbing robot includes a material grabbing plate 541 connected to the second lifting drive assembly and two finger cylinders 542 arranged side by side on the material grabbing plate. The two jaws of the finger cylinders are provided with arc grooves relative to each other. When grabbing the shaft, the two finger cylinders will move synchronously, and the two finger jaws of each finger cylinder will clamp the shaft through the arc groove. At the same time, it should be noted that the provision of two finger cylinders can ensure the stability of the movement of the shaft.

[0037] In the description of this specification, the description with reference to the terms "one embodiment", "example", "specific example", etc. means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described can be combined in any one or more embodiments or examples in a suitable manner.

[0038] The above embodiments are only for illustrating the technical concept and features of the present application, and their purpose is to enable technicians familiar with the technical field to understand the content of the present application and implement it accordingly, and they cannot be used to limit the protection scope of the present application.
