Description

Technical Field

[0001] The utility model relates to the technical field of automobile part processing, and specifically relates to a pull rope lifting device for a checking fixture. Background Art

[0002] In the automobile manufacturing industry, the quality inspection of welded assembly parts is an important link to ensure the quality of the whole vehicle. After these parts are welded, they need to be inspected by precise checking fixtures to verify whether their dimensions, shapes and positions meet the design requirements. During the inspection process, in order to simulate the actual installation state of the parts in the vehicle body, it is often necessary to adjust the position and posture of the parts to ensure the accuracy and reliability of the inspection results.

[0003] However, in actual operation, the shapes and sizes of welded assembly parts are diverse and often have complex geometric features. Especially in some cases, the positioning surface (i.e., the zero-contact surface) of the part is located at the upper part of the part, while the zero-contact surface of the checking fixture is located at the lower part. At this time, if the part is directly placed on the checking fixture for inspection, due to the action of gravity, the part cannot naturally fit onto the zero-contact surface of the checking fixture, resulting in deviation of the inspection results or inability to complete the inspection.

[0004] Traditional methods are to manually adjust the position of the part by hand or use automated equipment such as robotic arms to assist in positioning. However, these methods are not only inefficient but also prone to introducing human errors or mechanical errors, affecting the accuracy of the inspection results. Content of the Utility Model

[0005] The utility model aims at the technical problems existing in the prior art, and provides a pull rope lifting device for a checking fixture to solve the problem of low efficiency in manually adjusting the position of parts.

[0006] The technical solution of the utility model for solving the above technical problems is as follows: a pull rope lifting device for a checking fixture, including a zero-contact surface on the checking fixture and a lifting seat located below the zero-contact surface. A connecting rod that can slide in the vertical direction is arranged in the lifting seat, and a supporting block facing the zero-contact surface is arranged on the connecting rod; a sliding block is arranged at the bottom end of the connecting rod, and a lifting mechanism connected to the sliding block; the lifting mechanism is used to lift the sliding block so that the connecting rod drives the supporting block to approach the zero-contact surface.

[0007] Based on the above technical solution, the utility model can be further improved as follows.

[0008] Further, the lifting mechanism includes:

[0009] A fixed column located above the sliding block and slidably matched with the connecting rod;

[0010] A plurality of hollow limiting terminals arranged below the sliding block;

[0011] A steel wire rope is passed through the hollow limit terminal, penetrates the sliding block and is connected to the fixed column;

[0012] A metal sleeve which is sleeved outside the steel wire rope and clamped with the hollow limit terminal;

[0013] A pull rope assembly connected to the steel wire rope is used to pull the steel wire rope in the metal sleeve so that the metal sleeve and the hollow limit terminal push the sliding block to rise.

[0014] Further, the pull rope assembly comprises:

[0015] Limiting cylinder;

[0016] A wire drum slidably arranged in the limiting cylinder;

[0017] A pull rod axially penetrating the limiting cylinder and connected to the wire drum;

[0018] A fixed terminal is installed on the limiting cylinder and directly faces the wire drum, the fixed terminal is clamped with the other end of the metal sleeve, and the steel wire rope passes through the fixed terminal and is connected to the wire drum.

[0019] Furthermore, the fixed column is also provided with a plurality of guide pins which are slidably matched with the sliding block.

[0020] Furthermore, the guide pin is externally sleeved with a return spring for elastically supporting the fixed column and the sliding block.

[0021] Moreover, the inspection tool pulling rope lifting device provided by the utility model has at least the following beneficial effects compared with the prior art:

[0022] 1. The innovative lifting mechanism effectively solves the problem of fitting the welding assembly parts due to gravity during the quality inspection process. In the traditional method, the parts cannot naturally fit the zero surface of the inspection fixture due to gravity, resulting in deviation in the inspection results or failure to complete the inspection. However, this equipment uses the pull rope assembly to accurately control the rise of the sliding block and the connecting rod to ensure that the parts can fit the zero surface of the inspection fixture smoothly and accurately, thereby significantly improving the inspection accuracy. At the same time, the automated lifting process reduces manual intervention, improves inspection efficiency, and reduces the risk of human error.

[0023] 2. The guide pin ensures the stable movement of the sliding block in the vertical direction, effectively preventing deviation or shaking, and ensuring the stability of the lifting process. After the lifting task is completed, the reset spring uses elastic potential energy to automatically reset the sliding block and the connecting rod to the initial state without additional operation, which greatly simplifies the operation process. This automatic reset function not only improves work efficiency, but also extends the service life of the equipment and reduces maintenance costs. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] The principles and features of the present utility model will be described below with reference to the attached drawings. The examples given are only for explaining the present utility model and are not intended to limit the scope of the present utility model.

[0030] It should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "coupling" in the terms should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integrally formed structure. For those of ordinary skill in the art, the specific meanings of such terms in this patent can be understood according to specific circumstances.

[0031] As Figure 1 and Figure 2 shown, the inspection tool drawstring lifting device of the present utility model design includes a zero sticker 1 based on the inspection tool and a lifting seat 2 located below the zero sticker 1. A connecting rod 3 that can slide in the vertical direction is provided inside the lifting seat 2, and a supporting block 4 facing the zero sticker 1 is provided on the connecting rod 3; a sliding block 5 is provided at the bottom end of the connecting rod 3, and a lifting mechanism 6 connected to the sliding block 5; the lifting mechanism 6 is used to lift the sliding block 5 so that the connecting rod 3 drives the supporting block 4 to approach the zero sticker 1.

[0032] As an implementation manner, the lifting mechanism 6 includes:

[0033] A fixed vertical column 6.1 located above the sliding block 5 and slidably matched with the connecting rod 3; ensuring the stable movement of the connecting rod 3 in the vertical direction;

[0034] A number of hollow limiting terminals 6.2 arranged below the sliding block 5; providing a channel and a limiting function for the steel wire rope 6.3 to ensure that the steel wire rope 6.3 does not deviate from the predetermined path during the pulling process;

[0035] A steel wire rope 6.3 that passes through the hollow limit terminal 6.2, penetrates the sliding block 5, and is connected to the fixed column 6.1;

[0036] A metal sleeve 6.4 sleeved outside the steel wire rope 6.3 and clamped with the hollow limit terminal 6.2; It plays a role in protection and guiding, and is connected to the fixed terminal 6.8 of the pull rope assembly at the same time to transmit the pulling force to the sliding block 5

[0037] A pull rope assembly connected to the steel wire rope 6.3, and the pull rope assembly is used to pull the steel wire rope 6.3 in the metal sleeve 6.4 so that the metal sleeve 6.4 and the hollow limit terminal 6.2 push the sliding block 5 to rise.

[0038] Specifically, as Figure 3 shown, the pull rope assembly includes:

[0039] A limit cylinder 6.5; It provides a sliding track for the wire reel 6.6 and an installation position for the fixed terminal 6.8;

[0040] A wire reel 6.6 slidably arranged in the limit cylinder 6.5;

[0041] A pull rod 6.7 axially penetrating the limit cylinder 6.5 and connected to the wire reel 6.6; When the pull rod 6.7 is pulled, the wire reel 6.6 will move synchronously to pull the steel wire rope 6.3;

[0042] A fixed terminal 6.8 installed on the limit cylinder 6.5 and facing the wire reel 6.6, the fixed terminal 6.8 is clamped with the other end of the metal sleeve 6.4, and the steel wire rope 6.3 passes through the fixed terminal 6.8 and is connected to the wire reel 6.6.

[0043] As an implementation manner, a plurality of guide pins 7 slidably matched with the sliding block 5 are further arranged on the fixed column 6.1; A return spring 8 for elastically supporting the fixed column 6.1 and the sliding block 5 is sleeved outside the guide pin 7.

[0044] The jacking mechanism can not only accurately lift the sliding block 5 under the control of the pull rope assembly, but also automatically reset under the action of the return spring 8. The guide pin 7 ensures the stability of the movement of the sliding block 5, while the return spring 8 provides the reset function, enabling the jacking mechanism to automatically return to the initial state after completing the jacking task and be ready for the next operation. This design improves the automation degree and operation convenience of the jacking mechanism.

[0045] The working principle of the present utility model is as follows:

[0046] Initial state: In the initial state, the connecting rod 3 and the supporting block 4 are in a lower position, and the parts are not placed on the supporting block 4.

[0047] Pull rope operation: When it is necessary to lift the part, the operator applies a pulling force to the steel wire rope 6.3 through the pull rope assembly. The pull rope assembly includes a limit cylinder 6.5, a wire reel 6.6, a pull rod 6.7, and a fixed terminal 6.8. By pulling the pull rod 6.7, the wire reel 6.6 rotates within the limit cylinder 6.5, thereby tightening the steel wire rope 6.3.

[0048] Steel wire rope drive: The tightened steel wire rope 6.3 transmits the pulling force to the sliding block 5 through the metal sleeve 6.4 and the hollow limit terminal 6.2. Since the steel wire rope 6.3 is connected to the fixed column 6.1, the pulling force will push the sliding block 5 to rise along the fixed column 6.1.

[0049] Lifting process: As the sliding block 5 rises, the connecting rod 3 also rises, and then drives the supporting block 4 closer to the zero sticker 1. When the part is placed on the supporting block 4, the supporting block 4 will continue to rise until the part is lifted to a position where it fits with the zero sticker 1.

[0050] Stable state: After the part fits with the zero sticker 1, the lifting mechanism 6 maintains the pulling force to ensure that the part remains in a stable position during the detection process.

[0051] Reset operation is optional: After the detection is completed, by releasing the pulling force in the pull rope assembly, the sliding block 5, the connecting rod 3, and the supporting block 4 will return to their initial positions under the action of gravity or a reset spring (if any) for the next lifting operation.

[0052] It should be noted that in this article, the terms "include", "comprise", or any other variant thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or device including a series of elements not only includes those elements, but also includes other elements not explicitly listed, or elements inherent to such process, method, article, or device.
