Description

Technical Field

[0001] The utility model belongs to the technical field of bearing processing, and in particular relates to a detection device for needle roller processing. Background Art

[0002] The use of bearings on various types of mechanical equipment is very huge, and needle rollers, as the main components of bearings, directly affect the quality of bearings. Defective needle rollers have poor stress resistance, which not only affects the service life of bearings, but in some cases even endangers human life and property. Therefore, the appearance and size inspection links in the needle roller manufacturing process are very important. However, some existing inspection methods usually use manual measuring instruments for inspection, which results in slow manual inspection speed, which is not conducive to rapid inspection of the length of the needle roller, and thus causes inconvenience in inspection.

[0003] The Chinese utility model patent with publication number CN219129978U discloses a device for rapid detection of needle roller length. The device prevents the needle roller to be detected from being placed in the groove of a rotating disc. A second guide plate is provided above the disc to screen needle rollers longer than the standard length and push them out of the groove. A first guide plate is also provided on the disc to stop the needle rollers that meet the standard length from being adsorbed by the magnet, and then the needle rollers are quickly withdrawn from the notch on the support seat, thereby facilitating the withdrawal of the needle rollers from the support seat, reducing the difficulty of manual material collection, improving the convenience of material collection, and improving work efficiency. However, the device still has some other problems. For example, the device can only screen out needle rollers longer than the standard length, and those shorter than the standard length cannot be screened. Utility Model Content

[0004] The purpose of the utility model is to provide a detection device for needle roller machining to solve the problems raised in the above background technology.

[0005] In order to achieve the above-mentioned purpose, the following technical solution is provided: a detection device for needle roller machining, comprising:

[0006] Support frame;

[0008] A turntable is arranged on the output end of the motor, the turntable is provided with a groove, the inside of the groove is provided with a mounting opening, a magnetic block is fixedly installed through the mounting opening, and a stopper is fixedly installed on the periphery of the turntable between the two grooves;

[0009] A roller needle is arranged inside the groove;

[0010] A detection device, arranged above the turntable;

[0011] Wherein, the detection device comprises:

[0012] A connecting rod, arranged on the supporting frame;

[0013] A detection plate is arranged at the other end of the connecting rod, and a round hole is opened on a side of the detection plate close to the rotating disk;

[0014] The electric push rod is arranged inside the circular hole, and a detection sensor is arranged on the fixing seat of the electric push rod.

[0015] In the above technical solution, further, four openings are provided on the periphery of the support frame, which are respectively a feed port, a discharge port, a discharge port for over-long products and a discharge port for short products, wherein a conveying mechanism is provided on the periphery of the support frame near the openings.

[0016] In any of the above technical solutions, further, a push plate is provided on one side of the discharge port along the rotation direction of the turntable.

[0017] In any of the above technical solutions, further, the detection sensor is one of an ultrasonic sensor and an infrared sensor.

[0018] In any of the above technical solutions, further, the connecting rod is set with an adjustable length to change the distance between the detection plate and the groove.

[0019] In any of the above technical solutions, further, the detection plate is provided with a notch, and the notch is opposite to the discharge port of the extra-long product.

[0020] The beneficial effects of the utility model are:

[0021] 1. A detection device is designed on the support frame, and the detection plate is installed above the rotating turntable, and the top of the detection plate is connected to an electric push rod. A detection sensor is set at the position of the fixed electric push rod. The detection sensor can detect whether there is a gap between the top of the needle roller inside the groove of the turntable and the detection plate. After detecting that there is a gap between the needle roller and the detection plate, the output shaft of the electric push rod is controlled to separate the needle roller shorter than the qualified product from the magnetic block, so that it is pushed to the discharge port of the short product by the block.

[0022] 2. By opening a notch on the detection plate, the needle roller that is longer than the qualified product will be blocked by the notch of the detection plate. At the same time, the discharge port for extra-long products is set behind the feed port, so the needle roller that is longer than the qualified product can be blocked by the notch of the detection plate at the first time, so that the needle roller of the extra-long product is separated from the magnetic block and transported to the discharge port for extra-long products.
