Description

Technical Field

[0001] The utility model belongs to the technical field of double gear rapid positioning, in particular to a rapid positioning device for double gear processing. Background Art

[0002] A double gear is two coaxial gears that are separated by a certain distance and made into one. This type of double gear is called a sliding gear in the gear train (transmission). Its function is to change the rotational speed or speed of the output shaft. In the gearbox, if there is a sliding gear, there can be multiple rotational speeds or speeds. If there is no sliding gear, there is only one rotational speed or speed.

[0003] During the production and processing of existing double gears, the workpiece needs to be positioned, but the existing fixtures are cumbersome to operate and most of them cannot achieve fast and accurate positioning. Therefore, we propose a double gear rapid positioning device. Utility Model Content

[0004] The purpose of the utility model is to provide a rapid positioning device for double gear processing, by setting a connecting bracket and a connecting block, starting the output end of cylinder one to shrink toward the middle, and driving the fixed blocks on the left and right sides to shrink toward the middle through connecting shaft two, the connecting brackets on the left and right sides drive the connecting blocks to rotate due to the shrinkage of cylinder one, and the rotation of the connecting blocks simultaneously drives the connecting brackets on the front and back sides to rotate, and perform concentric rotation, so that the sliding jaw one and the sliding jaw two on the top are simultaneously clamped close to the middle, solving the problem of the existing center positioning that does not require frequent replacement of fixtures.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a rapid positioning device for double gear processing, comprising a positioning box and a flip box, wherein a positioning disc is fixedly connected to the bottom of the positioning box, a fixed shaft 1 is fixedly connected to the top of the positioning disc, a connecting block is rotatably connected to the outer surface of the fixed shaft 1, a sliding disc is fixedly connected to the top of the fixed shaft 1, four sliding grooves are provided inside the sliding disc, a fixed shaft 2 is fixedly connected to the outer surface of the connecting block, a connecting bracket is rotatably connected to the outer surface of the fixed shaft 2, and there are four connecting brackets, all of which are rotatably connected to the connecting shaft 1, and sliding clamps 2 are fixedly connected to the tops of the connecting shaft 1 located on the front and back sides, A sliding clamp 1 is fixedly connected to the top of the connecting shaft 1 on the left and right sides, and a fixed block is fixedly connected to the bottom of the sliding clamp 1 on the left and right sides. A connecting shaft 2 is fixedly connected inside the fixed block. By setting a connecting bracket and a connecting block, the output end of the cylinder 1 is started to shrink toward the middle, and the fixed blocks on the left and right sides are driven to shrink toward the middle through the connecting shaft 2. The connecting brackets on the left and right sides drive the connecting blocks to rotate due to the contraction of the cylinder 1, and the rotation of the connecting blocks simultaneously drives the connecting brackets on the front and back sides to rotate, and they rotate concentrically, so that the sliding clamp 1 and the sliding clamp 2 on the top are simultaneously clamped close to the middle, so that the workpiece to be processed can be quickly positioned.

[0007] Furthermore, a flip block is fixedly connected to the bottom of the sliding disc, a limiting block 2 is fixedly connected to the bottom of the flip block, and a limiting block 1 is fixedly connected to the left side of the flip block. By setting the flip block, cylinder 2 is started to move the right output end to the left side, driving the rack to slide inside the sliding block. When the rack slides to the left side, it drives the top gear to rotate, and the gear is driven by connecting shaft 3 to rotate the flip block to the right side. The flipping angle is limited by the limiting block 2 at the bottom of the flip block.

[0008] Furthermore, the front and back sides of the flip block are rotatably connected with a U-shaped plate, the left side of the U-shaped plate is fixedly connected with a limit plate, and the front side of the limit plate is fixedly connected with a sliding block. By setting the limit plate, the limit block can limit the flipping angle when flipping, and the device will not be damaged due to excessive flipping.

[0009] Furthermore, a connecting shaft three is fixedly connected inside the flip block, a gear is fixedly connected to the front of the connecting shaft three, a rack is meshingly connected to the bottom of the gear, and a cylinder two is fixedly connected to the right side of the rack. By setting the meshing connection between the rack and the gear, the gear can be rotated by pushing and pulling back through cylinder two, which saves resources and uses compressed air to drive the equipment to work.

[0010] Furthermore, a rack is fixedly connected to the right output end of the second cylinder, a second sliding groove is provided inside the sliding block, and the rack is slidably connected to the inside of the second sliding groove. By setting the second sliding groove, the rack can slide inside, which has the advantage of convenient installation and can also limit the position of the rack from being offset.

[0011] Furthermore, the front and back sides of the fixed shaft 1 are fixedly connected with cylinder 1, and the connecting shaft 2 on the left side is fixedly connected with the output end of cylinder 1. By setting the two ends fixedly connected, they can move simultaneously, and the high synchronization improves the flexibility of the equipment, and the operation is smooth and simple to manufacture.

[0012] The utility model has the following beneficial effects:

[0013] 1. The utility model sets a connecting bracket and a connecting block, starts the output end of the cylinder 1 to shrink toward the middle, drives the fixed blocks on the left and right sides to shrink toward the middle through the connecting shaft 2, and the connecting brackets on the left and right sides drive the connecting blocks to rotate due to the shrinkage of the cylinder 1. The rotation of the connecting blocks simultaneously drives the connecting brackets on the front and back sides to rotate, and the concentric rotation is performed, so that the sliding jaws 1 and 2 on the top are simultaneously clamped close to the middle, and the workpiece to be processed can be quickly positioned.

[0014] 2. The utility model sets a flip block, starts cylinder 2 to move the right output end to the left, drives the rack to slide inside the sliding block, and drives the top gear to rotate when the rack slides to the left. The gear is driven by connecting shaft 3, and the flip block rotates to the right. The flip angle is limited by the limit block 2 at the bottom of the flip block.

[0015] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
