Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a high-reliability positioning device for workpiece processing. Background Art

[0002] A positioning device for workpiece processing is a device used to ensure the accurate position of the workpiece during the processing process. It is usually used in processes such as mechanical processing, welding, and assembly. By fixing the workpiece or providing an accurate position reference, the position, size, shape and other requirements of the processing process can be met. The positioning device can include a fixture, a fixture assembly, a fixture fixture, a positioning pin, a positioning hole, a support block, etc. Its design principle is to ensure that the workpiece maintains a stable and accurate position during the processing process to improve processing efficiency and ensure product quality.

[0003] The application number is CN202122928383.7, which discloses a workpiece positioning device for wood product processing, including a fixed base plate, two symmetrically arranged threaded plates are fixedly installed on the upper end of the fixed base plate, the two threaded plates are threadedly connected with threaded rods, and a fixed disc is fixedly installed on one end of the two threaded rods facing the center of the fixed base plate, and the fixed disc is movably connected with a clamping plate, and a fixed plate is fixedly installed on the lower end of the fixed base plate, and an electric push rod is fixedly installed on the side wall of the fixed plate, and the electric push rod penetrates through the side wall of the fixed base plate to the side wall of the upper end of the fixed base plate and a support plate is fixedly installed, and the inner wall of the support plate is rotatably connected with a connecting plate, and the upper end of the connecting plate is fixedly installed with a supporting base plate, which is convenient for fixing logs of a certain volume, and rotating the logs by rotating the clamping plate during processing, thereby facilitating log processing, and the device has a simple structure and is easy to use.

[0004] Although this arrangement can drive the clamping plate to move by rotating the threaded rod, since the clamping plates at both ends need to be adjusted separately, it is impossible to ensure that the clamped object is located at the central axis of the fixed base plate, which can easily lead to inaccurate processing during symmetrical processing. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a high-reliability positioning device for workpiece processing.

[0006] The utility model is implemented by the following technical scheme: a high-reliability positioning device for workpiece processing, comprising a placement box, a servo motor is fixedly connected to the bottom wall of the placement box, a first threaded rod is fixedly connected to the output end of the servo motor, an end of the first threaded rod away from the servo motor is rotatably connected to the top wall of the placement box, a ball slider is threadedly connected to the outer wall of the first threaded rod, a connecting rod is rotatably connected to the outer wall of the ball slider, a sliding groove is provided at the top of the placement box, a first sliding rod is fixedly connected to the inner wall of the sliding groove, a sliding block is slidably connected to the outer wall of the first sliding rod, the sliding block is slidably connected to the inside of the sliding groove, a rotator is fixedly connected to the bottom of the sliding block, an end of the connecting rod away from the ball slider is rotatably connected to the inside of the rotator, and ends of the sliding blocks close to each other are fixedly connected to a fixing box.

[0007] Through the above technical solution, the servo motor is operated to drive the first threaded rod to rotate, and the rotation of the first threaded rod causes the ball slider to move up and down, thereby driving the bottom end of the connecting rod to move.

[0008] As a further improvement of the above scheme, the servo motor is located at the central axis of the placement box, four connecting rods are provided, and the connecting rods are symmetrically arranged with respect to the center of the ball slider, four slide grooves are provided, and the slide grooves are symmetrically arranged with respect to the center of the placement box, and four fixed boxes are provided, and the fixed boxes are symmetrically arranged with respect to the center of the placement box.

[0009] As a further improvement of the above scheme, the inner wall of the fixed box is fixedly connected to a second sliding rod, the outer wall of the second sliding rod is rotatably connected to a fixing ring, the outer wall of the fixing ring contacts the inner wall of the placement box, and the side of the fixing ring close to each other is fixedly connected to a spring, and the spring is located inside the fixed box.

[0010] Through the above technical solution, the movement of the fixed box drives the second slide bar to move, and the second slide bar pushes the fixed box to move, thereby clamping the workpiece.

[0011] As a further improvement of the above scheme, two second sliding rods are provided, and the second sliding rods are symmetrically arranged with the fixed box. Two fixing rings are provided, and the fixing rings and the second sliding rods are symmetrically arranged. The side of the fixing box away from the slider is arc-shaped, and the inner diameter of the fixing ring is the same as the radius of the side of the fixing box away from the slider.

[0012] As a further improvement of the above solution, a fixing plate is fixedly connected to one side of the fixing box away from the slider, a second threaded rod is threadedly connected inside the fixing plate, and both ends of the second threaded rod penetrate the outer wall of the fixing plate and extend.

[0013] As a further improvement of the above solution, the bottom of the second threaded rod is rotatably connected to a fixed block, and one end of the second threaded rod away from the fixed block is fixedly connected to a rotating rod.

[0014] Through the above technical solution, by rotating the rotating rod, the rotation of the rotating rod drives the second threaded rod to rotate, and the rotation of the second threaded rod causes the fixed block to move, thereby further fixing the workpiece.

[0015] The fixing plate is located on the top of the fixing box, four fixing plates are provided, and the fixing plates are symmetrically arranged around the center of the placement box, and the fixing block is circular.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] The utility model starts the servo motor clockwise, and the operation of the servo motor will drive the first threaded rod to rotate. Due to the limitation of the connecting rod, the ball slider will descend along the first threaded rod, and the ball slider will bring the bottom end of the connecting rod down, so that the top of the connecting rod is close to the center of the placement box, and the top of the connecting rod will drive the rotator to move, and the rotator drives the slider to move along the first slide rod toward the center of the placement box, the slider moves with the fixed box, the fixed box drives the second slide rod to move, and the second slide rod drives the fixed ring to move, because the fixed ring is symmetrically arranged with the center of the placement box and moves at the same time, the fixed ring will push the workpiece to the center of the placement box, thereby ensuring the accuracy of symmetrical engraving.

[0018] After the utility model contacts the workpiece through the symmetrical fixing ring, the servo motor continues to run. At this time, due to the obstruction of the workpiece, the fixing ring will rotate around the second sliding rod, and the fixing rings located outside the fixing box will move away from each other, so that the other ends of the fixing rings are close to each other. At this time, the spring will be compressed, and the spring will apply a reaction force to the fixing ring, so that the fixing ring will fix the workpiece more firmly. Then the rotating rod is rotated clockwise, and the rotating rod drives the second threaded rod to rotate. The rotation of the second threaded rod will lengthen the length of the second threaded rod at the bottom of the fixing plate, thereby driving the fixing block to move downward, so that the fixing block can longitudinally fix the workpiece to prevent the workpiece from moving during the processing.
