Description

Technical Field

[0001] The utility model relates to the technical field of hardware detection, in particular to a special grabbing mechanism for burr detection of small hardware. Background Art

[0002] During the processing of hardware products, burrs will be formed due to various reasons, which will cause the surface of the workpiece to be rough and increase the risk of injury to operators, especially when handling, which may scratch the skin or cause other accidents. At the same time, burrs may interfere with the normal function of parts, such as hindering assembly and affecting the smooth operation of moving parts, thereby reducing the performance and reliability of the product. Therefore, it is necessary to perform burr detection on the processed hardware and sort out the hardware with burrs for subsequent grinding and deburring.

[0003] In the prior art, hardware is usually clamped and fixed with a clamp, and burrs are detected by using a CCD camera. However, the existing clamps for clamping hardware cannot drive the hardware to rotate, and the CCD shooting angle is limited, and there are blind spots for shooting. It is impossible to shoot and detect the entire circumference of the hardware. Shooting and detection can only be performed by arranging multiple CCD cameras in different directions, which increases the investment in equipment costs. Even if multiple CCDs are set up to shoot and detect from different angles, there will be missed detections, which greatly reduces the accuracy of burr detection. Utility Model Content

[0004] The purpose of the utility model is to provide a special grabbing mechanism for detecting burrs of small hardware parts, which can improve the detection accuracy and effectively solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions.

[0006] A special grabbing mechanism for burr detection of small hardware comprises a mounting frame and a fixed seat, wherein the fixed seat is arranged above the mounting frame, a first driving mechanism is arranged above the mounting frame and located on one side of the fixed seat, the first driving mechanism is used to drive the fixed seat to translate left and right, a bearing seat is installed on the upper surface of the fixed seat, a shaft rod is rotatably installed on the bearing seat, a second driving mechanism is arranged on one side of the bearing seat on the fixed seat, the second driving mechanism is used to drive the shaft rod to rotate, a mounting block is fixed at one end of the shaft rod, a clamping cylinder is fixed on the mounting block, and two clamping claws for clamping hardware are symmetrically arranged on the clamping cylinder.

[0007] It can be seen that the second driving mechanism drives the shaft rod to rotate one circle, and under the fixed connection of the mounting block, it can drive the clamping cylinder, the clamping claw and the clamped hardware to rotate one circle, so that the entire circumference of the hardware can be photographed and inspected by the CCD, and there is no blind spot in the shooting and inspection, thereby ensuring the accuracy of the inspection results. In addition, there is no need to arrange multiple CCDs in different positions, which reduces the equipment cost investment, and the overall structural layout is reasonable and highly practical.

[0008] Furthermore, the second driving mechanism includes a fixed frame, a driving motor, a first pulley, a second pulley and a transmission belt. The driving motor is fixed to the fixed seat through the fixed frame, the first pulley is fixed to the output shaft of the driving motor, the second pulley is fixedly sleeved on the end of the shaft away from the mounting block, and the transmission belt is sleeved on the first pulley and the second pulley.

[0009] By driving the motor, its output shaft drives the first pulley to rotate, and the rotating first pulley can drive the second pulley and the shaft to rotate synchronously under the transmission action of the transmission belt, thereby providing stable drive for the hardware rotation detection. In addition, compared with the traditional transmission method, the utility model utilizes a rotating structure composed of the first pulley, the second pulley and the transmission belt, which can effectively reduce the vibration and noise during the transmission process and provide smoother power transmission. At the same time, the second pulley has a certain elasticity when transmitting power, which reduces the impact and vibration of the transmission to a certain extent, and helps to protect machine parts.

[0010] Furthermore, the first driving mechanism includes a bracket, a translation cylinder and a connecting arm, the bracket is fixed on the mounting frame, the translation cylinder is fixed on the bracket, the connecting arm is fixed on the end of the telescopic rod of the translation cylinder, and the side of the fixed seat is fixedly connected to the connecting arm.

[0011] The connecting arm is driven to move synchronously by the telescopic work of the translation cylinder, and then the fixed seat is driven to achieve a reciprocating translation effect, which facilitates the clamping cylinder and the clamping claw to switch back and forth between the loading station and the inspection station, thereby realizing the function of transferring the hardware from the loading station to the inspection station for easy inspection.

[0012] Furthermore, two guide rails are fixed on the upper surface of the mounting frame, and sliding seats are respectively installed on the two guide rails for limited sliding, and the tops of the two sliding seats are fixed to the lower surface of the fixed seat.

[0013] The sliding cooperation between the guide rail and the sliding seat can provide a limiting guiding function for the fixed seat, ensuring that the reciprocating translation of the fixed seat is smoother and more fluent. In addition, it can also provide a supporting effect for the fixed seat to ensure the stability of the entire structure.

[0014] Furthermore, a V-shaped groove is provided on each side of the two clamping jaws close to each other, and the inner wall of the V-shaped groove has anti-slip grooves. When the two clamping jaws are close to each other and clamped, the V-shaped grooves on the two clamping jaws jointly form a clamping cavity.

[0015] The V-shaped groove can be used to limit the position of the hardware, thereby ensuring that the hardware can be firmly clamped in the clamping cavity, avoiding the hardware from falling off due to loose clamping during the transfer and rotation process.

[0016] Furthermore, a protective cover is fixed on the upper surface of the mounting frame, the protective cover covers the fixing seat and the second driving mechanism, and the protective cover is provided with a first clearance opening that matches the bearing seat and a second clearance opening that matches the connecting arm.

[0017] The second driving mechanism is covered by a protective cover to avoid safety accidents caused by accidental touch. The first clearance opening makes room for the bearing seat, and the second clearance opening makes room for the connecting arm to ensure the adaptability of the structural layout.

[0018] Compared with the prior art, the beneficial effects of the present invention are as follows.

[0019] 1. The utility model drives the shaft to rotate one circle through the operation of the second driving mechanism, and under the fixed connection of the mounting block, it can further drive the clamping cylinder, the clamping claws and the clamped hardware to rotate one circle, so that the entire circumference of the hardware can be photographed and detected by the CCD, and there is no blind spot for shooting and detection, thereby ensuring the accuracy of the detection results. In addition, there is no need to arrange multiple CCDs in different positions, thereby reducing the equipment cost investment, and the overall structural layout is reasonable and highly practical.

[0020] 2. Compared with the traditional transmission method, the utility model utilizes a rotating structure composed of a first pulley, a second pulley and a transmission belt, which can effectively reduce vibration and noise during the transmission process and provide smoother power transmission. At the same time, the second pulley has a certain elasticity when transmitting power, which reduces the impact and vibration of the transmission to a certain extent and helps to protect machine parts.
