Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automobile parts detection equipment, specifically to a device for automobile parts detection. BACKGROUND

[0002] Automobile parts are products that constitute various functional units of an automobile, and there are many types. Since the quality of a single automobile part directly affects the quality of the whole automobile, automobile part detection work is an important link to improve the quality of the whole automobile. Since automobile parts have different shapes and types, detection personnel need to rotate the parts at multiple angles to complete the detection work. However, the overall quality of automobile parts is large, and it is difficult to determine the rotation angle by relying on manpower, so a power-assisted device is needed to rotate and fix the parts at multiple angles during detection.

[0003] In the prior art, a "turning device for automobile part detection" is disclosed in a Chinese patent application with application number CN202410853800.1. The turning device includes a support seat, a driving structure, a turning structure, a placement plate, a connection structure, a limiting structure, and a fixing structure. The driving structure can drive the turning structure to achieve multi-directional turning of the workpiece. In this technical solution, the turning action is controlled by the operator driving the motor. However, if the workpiece is heavy, the motor torque often cannot match the inertia of the workpiece, making it easy for the operator to turn the workpiece too much or end the turning action too early, resulting in a large error in the turning angle of the workpiece. This also makes it difficult for the operator to adjust the detection angle, reducing the detection efficiency of the operator. In addition, the fixing mechanism of this technical solution is composed of a screw, a sliding block, a clamping plate, a stop block, a rotating rod, and other structures cooperating with the placement plate. However, manual screwing of the screw is required to drive the sliding block, clamping plate, and other structures to move, which is time-consuming and labor-intensive. Therefore, further improvement is needed. UTILITY MODEL CONTENTS

DETAILED DESCRIPTION

[0034] The utility model will be further described in detail below in combination with the embodiment of the drawings.

[0035] Embodiment 1

[0036] As Figures 1-5 shown, it is the best embodiment of the utility model. The device for automobile accessory detection of this embodiment includes frame 1, rotatably arranged with rotating mechanism on frame 1, the rotating mechanism includes rotating shaft 2 rotatably connected with frame 1 and placing rack 3 fixedly connected on rotating shaft 2, the placing rack 3 is used to bear the workpiece 4 to be detected, and the fixing mechanism for fixing workpiece 4 on placing rack 3 is also arranged on placing rack 3.

[0037] With reference to Figure 5 , the fixing mechanism of this embodiment is the pneumatic locking mechanism arranged on the bearing rack 51 outwardly periphery from placing rack 3, the pneumatic locking mechanism includes first cylinder 52, locking seat 53, locking shaft 54 and locking piece 55, wherein, locking shaft 54 is arranged on locking seat 53, locking piece 55 is rotatably arranged on locking shaft 54, when locking piece 55 is subjected to the gas pressure force from first cylinder 52, it is rotated to workpiece, thereby closely extruding contact with the workpiece 4 to be locked, so that the operator can control first cylinder 52 to operate the pneumatic locking mechanism to press workpiece 4 on placing rack 3.

[0038] As Figures 1-4As shown, a brake mechanism is arranged around the rotating shaft 2, which acts on the rotating shaft 2 to stop the rotating movement of the rotating mechanism. Specifically, the rotating shaft 2 of the rotating mechanism extends into the end of the frame 1 and is provided with a brake disc 23 which rotates synchronously with the rotating shaft 2, and the brake mechanism includes brake members arranged on the frame 1 and acting on the brake disc 23, the power of which comes from the second cylinder 63 connected thereto. The brake members are two in total, which are sequentially a first brake member 61 and a second brake member 62, and are oppositely arranged on both sides of the brake disc 23. The first brake member 61 and the second brake member 62 have arc surfaces in contact with the brake disc 23. In order to enable the second cylinder 63 to simultaneously push the two brake members to compress the brake disc 23, a connecting rod mechanism is further arranged. It is particularly noted that Figure 4 the connecting rod mechanism includes a first connecting rod 72, a second connecting rod 73 and a third connecting rod 74, each of which is connected in a "U" shape, and the first connecting rod 72 and the third connecting rod 74 each include an upper segment, a lower segment and an intermediate segment connecting the upper segment and the lower segment, the first brake member 61 is connected to the intermediate segment of the first connecting rod 72, and the second brake member 62 is connected to the intermediate segment of the third connecting rod 74, the piston rod includes a first piston rod 631 at one end of the second cylinder 63 and a second piston rod 632 at the other end, and correspondingly, the connecting seat includes a first connecting seat 711 corresponding to the first piston rod 631 and a second connecting seat 712 corresponding to the second piston rod 632, the lower segment of the first connecting rod 72 is hinged with the first piston rod 631 through the first connecting seat 711, the lower segment of the third connecting rod 74 is hinged with the second piston rod 632 through the second connecting seat 712, the upper segment of the first connecting rod 72 is hinged with the first end of the second connecting rod 73, and the second end of the second connecting rod 73 is hinged with the upper segment of the third connecting rod 74, in the state that the second cylinder 63 retracts the first piston rod 631 and the second piston rod 632 by air pressure, each connecting seat can drive the first connecting rod 72, the second connecting rod 73 and the third connecting rod 74 to deflect, thereby driving the first brake member 61 and the second brake member 62 to lock the brake disc 23. As shown, Figure 6 when the brake disc 23 is in a free state, the first brake member 61 and the second brake member 62 do not contact the brake disc 23, when it is necessary to lock the brake disc 23, as shown, Figure 7 the second cylinder 63 can drive the piston rod by air pressure, so that the first connecting rod 72, the second connecting rod 73 and the third connecting rod 74 deflect, thereby stopping the rotation of the rotating shaft 2 by locking the brake disc 23.

[0039] The braking component can be single or multiple, as long as it can lock the brake disc 23. In this embodiment, two opposing brake components are provided to ensure uniform and stable locking of the brake disc 23 and to prevent excessive wear of a single brake component. The purpose of providing the brake disc 23 is mainly to increase the lever arm, thereby reducing the friction of the brake component and reducing its wear rate. Of course, this braking mechanism can also act on other parts of the mounting bracket 3 or the rotating shaft 2, such as a clamping plate that can clamp the mounting bracket 3, or a fastening brake pad that can lock the rotating shaft 2.

[0040] To facilitate operators in controlling the braking mechanism to complete braking actions, such as Figures 1-3 As shown, in this embodiment, a first foot switch 8 is connected to the braking mechanism via an air circuit, enabling the braking mechanism to perform braking actions. Of course, the first foot switch 8 can also be implemented in other ways, such as a foot brake that can be controlled by the foot, as long as it can be controlled by the foot. Specifically, the first foot switch 8 is connected to the second cylinder 63 of the braking mechanism via an air circuit. When the first foot switch 8 is in a free state, the piston rod 631 of the second cylinder 63 retracts, driving the first brake member 61 and the second brake member 62 to press and lock the brake disc 23, preventing it from rotating. When the first foot switch 8 is pressed, the state of the second cylinder 63 changes. At this time, each piston rod of the second cylinder 63 extends, causing the first brake member 61 and the second brake member 62 to release the pressure on the brake disc 23, allowing the brake disc 23 and its connected rotating shaft 2 to rotate, thus facilitating the operator to rotate the placement frame 3 to any predetermined angle. Because the process is pneumatically controlled, the rotating mechanism can be braked / released sensitively and quickly, eliminating the need for manual control and freeing the operator's hands for other tasks. Therefore, the rotating mechanism can be a hand-operated rotary wheel 21 coaxially mounted on the rotating shaft 2. The radius of this wheel 21 is larger than the rotating shaft 2, for example, more than ten times its diameter. This significantly reduces the force required to rotate the wheel 21 by increasing the lever arm length, facilitating manual rotation and control, and improving rotational accuracy. By using this hand-operated wheel 21, a motor and its associated power supply and control devices can be saved, and the rotation angle of the workpiece 4 can be more intuitively aligned with the operator's requirements. Furthermore, a handle 22 can be provided on the placement rack 3. When necessary, the operator can use one hand to operate the hand-operated wheel 21 and the other hand to operate the handle 22 to rotate the placement rack 3, resulting in more stable and precise rotation.

[0041] Example 2

[0042] As another embodiment of the utility model, the rest structure is same with the first embodiment, and the second foot switch is additionally arranged, and the first cylinder 52 of the pneumatic locking mechanism is connected through the gas circuit, when the second foot switch is stepped, the locking part 55 of the pneumatic locking mechanism is lifted, namely the workpiece 4 can be freely taken down.

[0043] Embodiment 3

[0044] As another embodiment of the utility model, the rest structure is same with the first embodiment, the solenoid valve is additionally arranged in the second cylinder 63, the first foot switch 8 is electrically connected with the solenoid valve, the spring is sleeved on the piston rod and connected with the bottom of the movable channel in the second cylinder 63, the spring makes the piston rod always have the tendency of extending to the outside of the second cylinder 63, and the opening or closing of the solenoid valve can be controlled under the state that the operator steps the first foot switch 8 to correspondingly control the second cylinder 63 to extend or retract the piston rod.

[0045] When operating, the operator first holds the hand control rotary wheel 21 and the handle 22, rotates the placing rack 3 to the loading angle, steps the first foot switch 8, and locks the placing rack 3 at the angle, then stably places the workpiece 4 on the placing rack 3, controls another pedal in the first foot switch 8 or other control switch, and locks the workpiece 4 on the placing rack 3 through the pneumatic locking mechanism. Subsequently, the operator steps the first foot switch 8 again, releases the rotating mechanism, rotates the workpiece 4 and the placing rack 3 to the predetermined angle, steps the first foot switch 8 to operate the brake mechanism, rapidly fixes the workpiece 4 at the predetermined angle, avoids the error caused by further rotation, and detects the workpiece 4. After detection, the operator can continue to step the first foot switch 8, rotates the placing rack 3, releases the pneumatic locking mechanism, and takes down the workpiece 4.
