Technical Field

[0001] The present invention relates to the technical field of quality inspection of vehicle parts, and particularly to an on-line performance tester for quality inspection of vehicle parts. Background Art

[0002] Vehicle parts are the basic units that make up an automobile and are used to achieve various functions of the automobile (such as power transmission, safety control, comfortable driving, etc.). They are usually made of materials such as metal, plastic, and rubber and need to meet performance requirements such as high precision, high strength, and wear resistance. During the quality inspection of vehicle parts, it is usually necessary to perform test operations on the surface roughness of vehicle parts to ensure that the parts can be used normally later.

[0003] According to a roughness detector for surface inspection of machined parts disclosed in the patent publication number CN 217403428 U, through the settings of structures such as a lateral support frame, a first adjustment frame, a second adjustment frame, an electric push rod, and a workpiece placement table, starting the electric push rod causes its output end to synchronously drive the detector body on the first adjustment frame and the second adjustment frame to adjust the height up and down. And starting the drive motor to drive the threaded rod to rotate, so that the sliding seat slides on the surface of the housing, and the horizontal position of the detector body can also be adjusted, so that the detection position can be adjusted according to the workpiece on the workpiece placement table, which not only reduces the labor intensity of the staff, but also improves the detection of the detector; however, this device cannot perform a fixing operation on the workpiece to be quality inspected, thus affecting the subsequent test operation on the workpiece and further affecting the applicability of the device.

The output end of the first electric telescopic rod 311 is fixedly connected with a fixing plate 312. A positioning groove 313 is opened on one side of the fixing plate 312. A positioning block 314 is clamped inside the positioning groove 313. A connecting plate 315 is fixedly connected to the outside of the positioning block 314. A rubber pad 316 is fixedly connected to the outside of the connecting plate 315. A clamping groove 317 and a pressing groove 318 are respectively opened on the side wall of the positioning block 314. An activity groove 319 is opened inside the fixing plate 312. An activity block 3110 is slidably connected to the inner wall of the activity groove 319. A clamping rod 3111 is fixedly connected to one side of the activity block 3110. A connecting rod 3113 is fixedly connected to the side of the activity block 3110 away from the clamping rod 3111. A first spring 3112 is fixedly connected to the inner wall of the activity groove 319. A pull rod 3114 is fixedly connected to the outer end of the connecting rod 3113. An activity hole is opened inside the pull rod 3114. A sliding rod 3115 is fixedly connected to the inner wall of the hole. A sliding block 3116 is slidably connected to the outer wall of the sliding rod 3115. A limiting rod 3117 is fixedly connected to the inside of the sliding block 3116. A limiting groove 3118 and a receiving hole are respectively opened in the front part of the fixing plate 312. And the limiting rod 3117 is movably connected inside the receiving hole. An inner groove 3119 is opened on the inner wall of the positioning groove 313. A pressing column 3120 is sleeved inside the inner groove 3119. A second spring 3121 is fixedly connected to the inner wall of the inner groove 3119.

[0021] In this embodiment, the clamping rod 3111 movably penetrates through the fixing plate 312 and is clamped with the clamping groove 317. One end of the first spring 3112 is fixedly connected with the activity block 3110. The limiting rod 3117 is adapted to the limiting groove 3118. The outer end of the connecting rod 3113 is movably connected with the fixing plate 312. Through the cooperation of the first electric telescopic rod 311 and the fixing plate 312, the vehicle parts can be pressed and fixed, so as to be more convenient for subsequent detection operations. And by setting the rubber pad 316, the workpiece is not easy to slide after being fixed, so that the fixing effect can be better. At the same time, through the cooperation of the positioning groove 313, the positioning block 314, the connecting plate 315, the clamping groove 317, the activity groove 319, the activity block 3110, the clamping rod 3111, the first spring 3112, the connecting rod 3113, the pull rod 3114, the sliding rod 3115, the sliding block 3116, the limiting rod 3117, and the limiting groove 3118, it is convenient for manual replacement of the rubber pad 316 with larger wear in time, so as to achieve a better fixing effect on the vehicle parts.

[0022] Further, one end of the second spring 3121 is fixedly connected to the pressing column 3120, and the pressing column 3120 is in pressing contact with the pressing groove 318. Through the cooperation of the inner groove 3119, the pressing column 3120, the second spring 3121, and the pressing groove 318, the connecting plate 315 can be assisted in fixing, thereby making it more convenient to install the rubber pad 316, and further increasing the applicability of the device.

[0023] When the device is in use, first, the vehicle parts are manually placed on the upper part of the placing plate 5, and then the first electric telescopic rod 311 drives the fixing plate 312 to move inward, so as to press and fix the workpiece. And under the action of the rubber pad 316, the fixing effect can be better. Further, when it is necessary to disassemble the rubber pad 316, only by manually holding the pull rod 3114 and pulling it outward, the connecting rod 3113 and the limiting rod 3117 can move outward synchronously. Furthermore, the movable block 3110 fixedly connected to the inner end of the connecting rod 3113 can drive the clamping rod 3111 to move outward, so that the clamping rod 3111 is separated from the clamping groove 317. And when the limiting rod 3117 moves outward and is separated from the receiving hole, the clamping rod 3111 and the clamping groove 317 are separated one step earlier. Subsequently, under the limiting action of the sliding rod 3115 and the sliding block 3116, by manually pulling the limiting rod 3117 and engaging the limiting rod 3117 with the limiting groove 3118, the clamping rod 3111 can stay at a position away from the clamping groove 317, enabling the worker to free up hands. Then, the connecting plate 315 can be taken out manually, so as to facilitate the worker to replace the worn rubber pad 316 in time. And when installing the connecting plate 315 and the rubber pad 316, by manually engaging the positioning block 314 fixedly connected to one side of the connecting plate 315 with the positioning groove 313 and pressing it inward, and then under the action of the elastic force of the second spring 3121, the pressing column 3120 can be pressed against the pressing groove 318, so as to press and fix the positioning block 314 in the positioning groove 313, and assist in fixing the connecting plate 315. Then, by manually separating the limiting rod 3117 from the limiting groove 3118 and matching the limiting rod 3117 with the receiving hole, and then under the action of the elastic force of the first spring 3112, the movable block 3110 can drive the clamping rod 3111 to move inward and engage with the clamping groove 317, so as to further fix the positioning block 314, and the fixing effect of the connecting plate 315 can be achieved, that is, the installation operation is completed, and the operation is simple and convenient.

[0026] After the vehicle parts are fixed, the hydraulic cylinder 325 drives the adjusting plate 326 to move downward, so that the detector body 3210 arranged below the adjusting plate 326 can move downward synchronously, making it contact with the surface of the workpiece. Then, the roughness of the surface of the vehicle parts can be detected. And the motor 321 drives the lead screw 322 to rotate, so that the adjusting block 324 threadedly connected to the outer wall of the lead screw 322 drives the hydraulic cylinder 325 to move left and right. And the second electric telescopic rod 327 drives the cross connecting block 329 to move in the cross slide rail 328, so that the detector body 3210 installed below the cross connecting block 329 can move back and forth.
