Description

Technical Field

[0001] The utility model relates to the technical field of clock and watch assembly devices, in particular to a device that is convenient for assembling clock and watch workpieces. Background Art

[0002] The parts inside a clock generally include several transition wheels, torsion springs, brake claws and rotating bodies. With the continuous development of science and technology, the assembly method of clocks has changed. The assembly of some clocks has gradually replaced manual assembly with mechanical assembly, which greatly improves the efficiency of clock assembly.

[0003] A search revealed an invention patent with publication number CN117420748, which specifically discloses a watch assembly method, including the following steps: 1. Gear train assembly: S11, securing the base; S12, assembling the second transition wheel; S13, assembling the first transition wheel; S14, assembling the riding wheel; S15, assembling the balance wheel; S16, assembling the rotating body; S17, assembling the pressure plate fixture; 2. Assembly of the rotating body and the brake pawl: S21, rotating the rotating body; S22, assembling the left brake pawl; S23, assembling the right brake pawl; 3. Assembly of the upper cover, left torsion spring, and right torsion spring: S31, removing the pressure plate fixture using an external device; S32, assembling the left torsion spring; S33, assembling the right torsion spring; S34, assembling the upper cover. Advantages: This method automatically overcomes the problem of gear misalignment, achieving automatic meshing between gears without requiring prior gear position correction, improving assembly efficiency and reducing assembly costs. The assembly sequence of the entire steps can effectively improve the efficiency of watch assembly, reduce assembly costs, and reduce the difficulty of watch verification after assembly.

[0004] In the above patent, multiple parts cooperate with each other to achieve the need for pre-correction of the position of the gears, thereby improving assembly efficiency and reducing assembly costs. Mechanical assembly generally uses a multi-axis manipulator to drive the clamps or suction cups to adsorb and clamp the parts, and then place the parts in the watch case. However, after multiple parts are placed on the existing tooling, because the tooling is installed and fixed under the clamps, when the tooling is transported and installed on the assembly platform, the shaking of the positioning tooling is likely to cause the parts to shake, resulting in inaccurate positioning of the parts by the suction cups and clamps, and making it difficult to remove the parts from the tooling, affecting the efficiency of mechanical assembly.

[0005] Therefore, it is necessary for us to propose a device for assembling clockwork to solve the above problems. Utility Model Content

[0006] The purpose of the utility model is to provide a device that is convenient for assembling watch workpieces. Through the mutual cooperation between the internal parts of the clamping mechanism, the positioning tooling can be moved during transportation, and the parts are clamped and fixed in the positioning tooling. Through the mutual cooperation between the internal parts of the telescopic mechanism, it is convenient to drive the parts to extend a part from the positioning tooling, so as to facilitate the assembly of the clamping claw assembly to locate and pick up the parts on the positioning tooling, so as to solve the problem in the prior art that when the tooling is transported and installed on the assembly platform, the shaking of the positioning tooling easily drives the parts to shake, resulting in inaccurate positioning of the parts by the suction cup and the clamping claw, and making it difficult to remove the parts from the tooling, thereby affecting the efficiency of mechanical assembly.

[0007] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: a device for assembling watch workpieces, comprising an assembly platform, a four-axis robot is mounted and fixed on the top of the assembly platform, an assembly clamping jaw assembly is mounted and fixed on one end of the four-axis robot, a clamping mechanism is mounted and connected to the top of the assembly platform and is located below the assembly clamping jaw assembly, and a telescopic mechanism is slidably connected to the inside of the clamping mechanism and extends to the top of the clamping mechanism.

[0008] Preferably, the clamping mechanism includes a positioning tool, which is installed and connected to the top of the assembly platform, passes through the interior of the assembly platform, and is located below the assembly clamping jaw assembly. Support columns are slidably connected to both sides of the positioning tool and pass through the interior of the positioning tool. A contraction spring is connected and fixed to one side of the support column that passes through the interior of the positioning tool. A connecting gear is provided above the support column and is rotatably connected to the interior of the positioning tool. The top of the connecting gear is rotatably connected to a support shaft and is located inside the positioning tool. A connecting tooth block is provided at the bottom end of the support shaft and is meshed with the connecting gear. A clamping block is connected and fixed to one side of the top end of the support shaft.

[0009] Preferably, the telescopic mechanism includes a conical block, which is connected and fixed to the top of the support column and is located inside the positioning tool. The positioning tool is slidably connected to a connecting column inside and is located on one side of the conical block. The top of the connecting column is connected and fixed to the telescopic column and is slidably connected to the inside of the positioning tool. The top of the telescopic column is connected and fixed to a support plate and passes through the top of the positioning tool. A limiting plate is provided at the top of the connecting column and is sleeved on the outer wall of the telescopic column. The top of the limiting plate is connected and fixed to a telescopic spring and is sleeved on the outer wall of the telescopic column.

[0010] Preferably, the top of the assembly platform is provided with a mounting groove matching the positioning tool, the interior of the positioning tool is provided with a sliding groove matching the support column, and the top of the positioning tool is provided with placement grooves for different parts.

[0013] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0014] 1. The installation slot on the assembly platform makes it easy for workers to install and fix the positioning tooling on the assembly platform. When the positioning tooling is installed and fixed to the assembly platform, the inner wall of the assembly platform contacts the support columns on both sides of the positioning tooling and squeezes the support columns, causing the support columns to squeeze and move the contraction springs. The movement of the support columns drives the connecting gear to rotate through the tooth grooves, and the rotation of the connecting gear drives the connecting gear block to move through the tooth block. The connecting gear block drives the support shaft to rotate, and the rotation of the support shaft drives the clamping block to rotate, so that the clamping block moves to release the clamping of the parts on the positioning tooling. This means that before the positioning tooling and the assembly platform are installed, the parts are clamped and fixed on the positioning tooling, thereby reducing the shaking of parts when the positioning tooling is transported.

[0015] 2. Move the support column to move the conical block, so that the conical block moves and contacts the connecting column, so that the connecting column is subjected to force to drive the limit plate to squeeze the telescopic spring to contract and move, the movement of the connecting column drives the movement of the telescopic column, the movement of the telescopic column drives the support plate to move, and the movement of the support plate drives the parts on the positioning tooling to be moved out of the positioning tooling, so that the four-axis robot can locate and pick up the parts on the positioning tooling by assembling the gripper assembly.
