Description

Technical Field

[0001] The utility model relates to the technical field of clamp spring assembly, in particular to a clamp spring assembly. Background Art

[0002] The retaining spring of the disc brake upper pump is an internal retaining spring, which is usually installed in the groove of the piston hole to maintain the pressure and stability of the brake system, thereby ensuring the braking effect. In order to improve the assembly efficiency of retaining springs and realize automated production, retaining spring press machines for automatically assembling retaining springs have appeared on the market, which usually include a retaining spring feeding part and a retaining spring press part. For example, the utility model patent with patent number CN116765795A discloses a retaining spring press machine for a motor, including a clamping mechanism and a first feeding device, wherein the clamping mechanism includes a rotary drive assembly, a first gear, a second gear and two retaining spring clamping needles, wherein the first gear and the second gear are arranged side by side on the lifting frame and mesh with each other, and the rotary drive The driving assembly is arranged on the lifting frame and is transmission-connected with the first gear. The two clamping spring clamping needles are respectively connected with the first gear and the second gear and are located at the bottom of the lifting frame. The first gear and the second gear are both provided with a plurality of small teeth, and the plurality of small teeth are arranged in sequence around the first gear or the second gear. The first gear and / or the second gear are also provided with a plurality of large teeth, and the plurality of large teeth are located between two adjacent small teeth. The tooth thickness of the large teeth is greater than the tooth thickness of the small teeth, and the full tooth height of the large teeth is greater than the full tooth height of the small teeth. When the first gear and the second gear are When the gears are rotated together to move the large toothed portion to between the first gear and the second gear, the large toothed portion opens the first gear and the second gear to move the second gear in a direction away from the first gear, thereby making the two retaining spring clamping needles move away from each other. The first loading device includes a first translation drive assembly and a material tray. The material tray is movably arranged on the frame. A positioning portion that cooperates with the retaining spring is arranged on the material tray. The material tray moves to the bottom of the retaining spring clamping needle under the drive of the first translation drive assembly. A retaining spring storage barrel is provided on the frame. The retaining spring storage barrel is arranged above the material tray. The positioning portion is a groove arranged on the material tray. The first translation drive assembly drives the material tray to move , so that the positioning part moves between the bottom of the circlip clamping needle and the bottom of the circlip storage barrel. When the positioning part moves to the bottom of the circlip storage barrel, the circlip on the circlip storage barrel falls into the positioning part. A positioning protrusion is provided on the outside of the circlip storage barrel. The positioning protrusion extends from top to bottom. When the circlip is sleeved on the outside of the circlip storage barrel, the two ends of the circlip are respectively located on both sides of the positioning protrusion. In the actual production process, there are the following disadvantages: 1. The meshing transmission of the first gear and the second gear is used to expand the circlip, which has high requirements on the accuracy of the gears, resulting in increased production costs. Moreover, after the two gears are meshed, the outer diameter of the circlip cannot be further reduced, which limits the installation method of the circlip; 2. Figure 4As shown in the figure, when the retaining spring clamping needle cooperates with the retaining spring, its end extends outside the retaining spring, which cannot be applied to the installation structure with a retaining spring groove. The end of the retaining spring clamping needle will conflict with the bottom of the groove, resulting in the retaining spring being unable to be installed to the bottom of the groove. Therefore, it cannot be applied to the retaining spring assembly of the disc brake upper pump; 3. When taking the retaining spring out of the material tray, only the retaining spring clamping needle is inserted into the retaining spring hole to position the retaining spring. There are too few positioning structures for the retaining spring. When the retaining spring clamping needle is lowered with the lifting frame, there is vibration, which can easily cause the retaining spring to fall off the needle and fly out; 4. Combined with the instructions attached Figure 1 It can be known that the retaining spring storage barrel in the first feeding device is fixed on the frame, and the retaining spring storage barrel will vibrate with the action of the lifting mechanism, and the material tray will also vibrate when it moves. Since there is no connection between the retaining spring storage barrel and other components in the first feeding device, the vibration frequency of the retaining spring storage barrel is different from the vibration frequency of the material tray. Over time, misalignment occurs between the retaining spring storage barrel and the material tray, resulting in the retaining spring not being able to fall into the positioning portion smoothly, affecting assembly; 5. The retaining spring storage barrel is located above the material tray, and the retaining spring is sleeved on the outside of the retaining spring storage barrel. The bottom of the retaining spring storage barrel is roughly flush with the top of the material tray. However, the end of the retaining spring storage barrel lacks a guide block for straightening the retaining spring, resulting in the retaining spring not being able to fall into the positioning portion smoothly.
