And the transfer mechanism is used for transporting the detected workpieces to the detection platform one by one and keeping a clamping state. The size detection mechanism comprises a distance measuring device, a clamping piece and a displacement driving assembly.

According to the utility model, the two clamping pieces which are slidably connected are arranged on the detection platform and are matched with the transfer mechanism to form cross-shaped clamping on the detected workpiece, so that the detected workpiece is ensured to be uniformly stressed during detection, and the situation that the detected workpiece is inclined due to single-side pressure application and the accuracy of size data obtained by detection is influenced is avoided.

Description

Technical Field

[0001] The utility model belongs to the technical field of automobile part processing, and particularly relates to a detection device for automobile parts. Background Art

[0002] In the prior art, due to the complex types of automobile parts and the large size differences between different automobile parts, in order to ensure the accuracy of the detection results, different detection tools need to be selected when detecting different parts. Moreover, when detecting the dimensions of some parts with relatively simple structures, such as length and width, manual detection is usually adopted. However, manual detection not only greatly reduces the detection efficiency and prolongs the detection time, but also increases the workload of the staff. The long-term detection work may reduce the attention of the operators and lead to errors in the detection results.

[0003] For the existing automatic dimension detection tooling for automobile parts, the workpiece to be measured is usually placed on the detection platform, and a single-direction clamping force is applied to cooperate with the corresponding tooling to complete the clamping of the workpiece to be measured. However, the magnitude of this clamping force is difficult to control. If it is too large, it is easy to cause deformation of the workpiece to be measured; if it is too small, it is easy to cause the workpiece to be measured to shift and tilt. At the same time, applying the clamping force unidirectionally is easy to cause uneven stress on the workpiece to be measured, which in turn causes the workpiece to be measured to tilt in the horizontal direction. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the prior art, the utility model provides a detection device for automobile parts to solve the technical problems such as the difficulty in controlling the magnitude of the clamping force when clamping the workpiece to be measured and the uneven stress on the workpiece to be measured.

[0005] To achieve the above object, the specific technical solution of the utility model is as follows:

[0006] A detection device for automobile parts, including a detection platform,

[0007] a transfer mechanism, which is used to transport the workpieces to be measured to the detection platform one by one and maintain the clamping state.

[0008] a dimension detection mechanism, which includes a distance measuring device, clamping members and a displacement driving assembly. The two clamping members are slidably connected to both sides of the detection platform. Both clamping members can move towards one side of the detection platform under the drive of the displacement driving assembly and cooperate with the transfer mechanism to form a cross-shaped clamping of the workpiece to be measured. The distance measuring device is used to detect the corresponding dimensions of the workpiece to be measured in the clamping state.

[0009] Further, the dimension detection mechanism further includes two sliding bases. The two sliding bases are slidably connected to both sides of the detection platform. Two clamping members are fixed on the opposite sides of the two sliding bases.

[0010] Further, the distance measuring device adopts a telescopic displacement sensor. The telescopic displacement sensor is fixed on one of the sliding bases, and the detection end abuts against the other sliding base.

[0011] Further, the displacement driving assembly includes a spring and a spreading cylinder. Mounting frames are fixed on both sides of the detection platform. The two springs are respectively installed on one side of the two mounting frames facing the two sliding bases. The sliding base can move towards the detection platform side under the drive of the corresponding spring to clamp the workpiece to be measured.

[0012] The spreading cylinder is fixed between the two sliding bases. The two sliding bases can move away from each other under the drive of the spreading cylinder.

[0013] Further, the transfer mechanism adopts an industrial robot.

[0014] Compared with the prior art, the utility model has the following advantages:

[0015] By arranging the two clamping members slidably connected to the detection platform in the utility model. Both clamping members can move towards the detection platform side under the drive of the displacement driving assembly, and cooperate with the transfer mechanism to form a cross-shaped clamping of the workpiece to be measured, ensuring uniform force on the workpiece to be measured during detection, avoiding tilting of the workpiece to be measured caused by unilateral pressure application, and further affecting the accuracy of the measured dimension data.

[0016] In the utility model, two springs are used in cooperation with a spreading cylinder to drive the two clamping members to move. When the thrust of the spreading cylinder is released, the sliding base is driven by the spring to move towards the detection platform, and the two clamping members cooperate with each other to clamp the workpiece to be measured placed on the detection platform, which can avoid deformation of the workpiece to be measured caused by excessive clamping force while completing the clamping of the workpiece to be measured.

[0020] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by terms such as "one end", "the other end", "outer side", "upper", "inner side", "horizontal", "coaxial", "center", "end portion", "length", "outer end", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model 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 should not be construed as a limitation to the present utility model.

[0021] The present utility model will be further described below with reference to the drawings.

[0022] As Figure 1 and 2 shown, a detection device for automotive parts includes a base, and a detection platform 1, a transfer mechanism 3 and a dimension detection mechanism 2 provided on the base. Among them, the transfer mechanism 3 is used to transport the workpieces to be measured to the detection platform 1 one by one and maintain a clamped state. The dimension detection mechanism 2 is used to clamp and detect the edges of the corresponding sides of the workpiece to be detected, and measure the corresponding width or length dimension of the workpiece to be detected. The transfer mechanism 3 and the dimension detection mechanism 2 form a cross-shaped clamping, which can effectively reduce the deformation influence caused by the clamping detection on the workpiece to be detected.

[0023] The specific structure is that the dimension detection mechanism 2 includes a distance measuring device 2-1, a sliding base 2-2 and a displacement driving component 2-4. The two sliding bases 2-2 are symmetrically arranged on both sides of the detection platform 1 and are both slidably connected to the base. On one side of the two sliding bases 2-2 facing the detection platform 1, there are clamping members 2-3 for clamping the workpiece to be detected. During operation, the two clamping members 2-3 can move away from or close to the detection platform 1 under the drive of the displacement driving component 2-4, and complete the clamping of the workpiece to be detected when approaching, and release the clamping when moving away.

[0024] In this embodiment, the transfer mechanism 3 uses an industrial robot. During operation, the industrial robot transports the workpiece to be measured onto the detection platform 1 and maintains a clamped state. The two clamping members 2-3 move towards the detection platform 1 under the drive of the displacement driving component 2-4 and clamp the workpiece to be detected. The distance measuring device 2-1 is arranged on one of the sliding bases 2-2 and can detect the size of the workpiece to be detected.

[0025] As Figure 2As shown, the distance measuring device 2-1 uses a telescopic displacement sensor. The telescopic displacement sensor is fixed on one of the sliding bases 2-2, and the detection end abuts against the other sliding base 2-2. During operation, the two sliding bases 2-2 move towards each other driven by the displacement driving assembly 2-4, causing the detection end of the telescopic displacement sensor to be compressed. The displacement generated by the compression is used to measure the size of the product, and then measurement data corresponding to the length or width of the workpiece to be measured is formed.

[0026] As Figure 2 shown, the displacement driving assembly 2-4 includes a spring 2-4-1 and a spreading cylinder 2-4-2. Among them, mounting brackets fixed by bolts are provided on both sides of the base. The two springs 2-4-1 are respectively installed on the side of the two mounting brackets facing the sliding base 2-2. The sliding base 2-2 and the clamping member 2-3 move towards the detection platform 1 under the drive of the two springs 2-4-1, thereby completing the clamping of the workpiece to be measured.

[0027] In this embodiment, the spreading cylinder 2-4-2 uses a two-way cylinder. The two-way cylinder is fixed in the middle of the base, and the two piston rods respectively abut against the two sliding bases 2-2. The two sliding bases 2-2 can move in opposite directions under the drive of the two-way cylinder. When it is necessary to release the clamping of the workpiece to be measured, the two piston rods of the two-way cylinder retract, releasing the thrust on the two sliding bases 2-2. Driven by the spring 2-4-1, the sliding base 2-2 moves towards the detection platform 1, and the two clamping members 2-3 cooperate with each other to clamp the workpiece to be measured placed on the detection platform 1.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention.
