Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of automobile parts processing, and particularly relates to a limiting guide mechanism for automobile parts. Background Art
[0002] With technological advancements, the precision requirements for automotive parts are becoming increasingly demanding. After machining, automotive parts require dimensional inspection. Traditionally, automotive parts inspection involves placing the part directly on a testing device. Sliding stoppers are then used to perform position measurement.
[0003] However, when the part being tested is placed on the inspection device, it may tilt horizontally or intersect the sliding direction of the sliding stop. If the tilt angle is too large, the sliding stop will cause the workpiece to remain tilted when clamping it, resulting in detection errors in the inspection device, which can easily lead to misjudgments and waste resources. Utility Model Content
[0004] In order to make up for the deficiencies of the prior art, the utility model provides a limit guide mechanism for automobile parts to solve the technical problem that the detection device may have detection errors on the measured workpiece due to the tilt of the measured workpiece.
[0005] In order to achieve the above purpose, the specific technical solutions of the present utility model are as follows:
[0006] A limiting guide mechanism for automobile parts, comprising
[0007] The limiting mechanism includes a limiting base and a limiting assembly. The limiting base defines a limiting slot. A detection member is provided at the input end of the limiting slot for detecting the input of the workpiece being detected. The limiting assembly includes a push cylinder and a limiting cylinder, each of which is disposed at either end of the limiting slot.
[0008] The guide assembly includes a limiting guide and a guide cylinder. The limiting guide is arranged on one side of the limiting slot and can be extended or retracted in a direction perpendicular to the limiting slot under the drive of the guide cylinder.
[0009] The horizontal jacking assembly includes a jacking cylinder and a jacking piece. The jacking piece is arranged in a limit groove and can be raised or lowered under the drive of the jacking cylinder.
[0010] Furthermore, a push rod and a limit rod are fixed to the piston rods of the pushing cylinder and the limit cylinder respectively. The shapes of the ends of the push rod and the limit rod match the workpiece to be measured.
[0011] Furthermore, the limiting base includes a base body and two limiting frames. The two limiting frames are fixed to the two side edges of the top of the base body by bolts, and the spaced area between them forms a limiting groove for limiting the state of the workpiece to be measured.
[0012] Furthermore, a clearance groove is provided in the limiting groove to match the lifting member. The clearance groove is located at the center of the bottom surface of the limiting groove. The top of the lifting member is located in the clearance groove.
[0013] Furthermore, in the initial state, the top of the lifting member is flush with the top of the clearance groove.
[0014] Furthermore, the detection element adopts a distance sensor.
[0015] Compared with the prior art, the utility model has the following advantages:
[0016] 1. The utility model respectively provides a pushing cylinder and a limiting cylinder at both ends of the limiting groove, so that the workpiece to be measured entering the limiting groove can be limited to the middle of the limiting groove. At the same time, by providing a limiting guide on one side of the limiting groove, the limiting guide can be driven by the guide cylinder to extend or retract in a direction perpendicular to the length direction of the limiting groove, and cooperate with the side wall of the limiting groove to guide the inclined workpiece to be measured in the limiting groove, so that the two side edges of the workpiece to be measured after correction are parallel to the side wall of the limiting groove, thereby avoiding the tilt of the detection clamping side edge of the workpiece to be measured intersecting with the detection end of the detection device when the workpiece is detected, thereby avoiding the occurrence of misjudgment.
[0017] 2. The present invention provides a lifting member at the center of the bottom surface of the limit slot, which can be raised or lowered by a lifting cylinder. The workpiece under test can be adjusted horizontally under the influence of the lifting member, thereby avoiding detection errors caused by horizontal tilt. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] In the description of the present invention, it should be understood that the terms "one end", "the other end", "outside", "upper", "inside", "horizontal", "coaxial", "center", "end", "length", "outer end", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.
[0023] The present invention will be further described below with reference to the accompanying drawings.
[0024] like Figure 1 and 2 As shown, a limiting and guiding mechanism for automotive parts includes a limiting mechanism 1, a guide assembly, a detection component 4, and a horizontal lifting assembly 3. The limiting mechanism 1 includes a limiting base 1-1 and a limiting assembly 1-2. A limiting slot is defined in the limiting base 1-1. The detection component 4 is positioned on one side of the limiting slot input end and is used to detect the input of the workpiece being inspected.
[0025] like Figure 3 As shown, during operation, the workpiece to be measured is input into the limit slot one by one through the vibrating loader 5. After entering the limit slot, the workpiece to be measured can be limited in the middle of the limit slot under the push and limit of the limit component 1-2. The guide component is arranged on one side of the limit slot, and can limit the two corresponding side walls on the workpiece to be measured in cooperation with the side walls of the limit slot, so that it is parallel to the side walls of the limit slot, thereby avoiding errors in size detection caused by the tilt of the workpiece to be measured. The horizontal lifting component 3 is arranged in the limit slot, and is used to horizontally limit the workpiece to be measured in the limit slot, so as to avoid size detection deviations due to the tilt of the workpiece to be measured in the horizontal direction. The workpiece to be measured that has completed the limit guide is output one by one by the industrial robot.
[0026] In this embodiment, the limiting base 1-1 includes a base body and two limiting frames. The two limiting frames are fixed to the two side edges of the top of the base body by bolts, and the spaced area between them forms a limiting groove for limiting the state of the workpiece to be measured.
[0027] like Figure 2As shown, the limiting assembly 1-2 includes a push cylinder and a limiting cylinder. The push cylinder and the limiting cylinder are respectively arranged at the two ends of the limiting groove. A push rod 1-2-1 and a limiting rod 1-2-2 are fixed to the piston rods of the push cylinder and the limiting cylinder, respectively. The end shapes of the push rod 1-2-1 and the limiting rod 1-2-2 match the workpiece to be measured. During operation, the piston rods on the push cylinder and the limiting cylinder extend toward each other. Under the mutual cooperation of the push rod 1-2-1 and the limiting rod 1-2-2 on the push cylinder and the limiting cylinder, the workpiece to be measured is confined to the middle of the limiting groove.
[0028] The guide assembly includes a limit guide 2 and a guide cylinder. The limit guide 2 is positioned on one side of the limit slot. Driven by the guide cylinder, the limit guide 2 extends or retracts perpendicular to the length of the limit slot, cooperating with the side walls of the limit slot to align the tilted workpiece within the limit slot, ensuring that the two side edges of the workpiece are parallel to the side walls.
[0029] The horizontal lifting assembly 3 includes a lifting cylinder and a lifting member. A clearance groove that matches the lifting member is provided in the limit groove. The clearance groove is located in the center of the bottom surface of the limit groove. The top of the lifting member extends into the clearance groove and can be pushed upward or dropped back downward under the drive of the lifting cylinder. In the initial state, the top of the lifting member is flush with the top of the clearance groove. After the limiting guide 2 completes the correction of the workpiece to be measured, the lifting member is driven upward by the lifting cylinder, thereby driving the workpiece to be measured to be adjusted in the horizontal direction.
[0030] In this embodiment, the detection member 4 on the input end side of the limiting groove is a distance sensor.
[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the above embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the above embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the scope of the technical solutions of the embodiments of the present invention.
