Description

Technical Field

[0001] The utility model relates to the technical field of clamp spring assembly, in particular to a feeding mechanism of a clamp spring assembly machine. 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 first feeding device, which includes a first translation drive assembly and a material tray. The material tray is movably arranged on a frame, and a positioning part that cooperates with the retaining spring is arranged on the material tray. The material tray moves to the retaining spring clamping position under the drive of the first translation drive assembly. Under the needle, a retaining spring storage barrel is provided on the frame, and the retaining spring storage barrel is arranged above the material tray, and the positioning part is a groove arranged on the material tray, and the first translation drive assembly drives the material tray to move so that the positioning part moves between the bottom of the retaining spring clamping needle and the bottom of the retaining spring storage barrel. When the positioning part moves to the bottom of the retaining spring storage barrel, the retaining spring on the retaining spring storage barrel falls into the positioning part, and a positioning protrusion is provided on the outside of the retaining spring storage barrel, and the positioning protrusion extends in the direction from top to bottom. When the retaining spring is sleeved on the outside of the retaining spring storage barrel, the two ends of the retaining spring are respectively located on both sides of the positioning protrusion. The above retaining spring storage barrel has the following disadvantages in the actual production process: 1. Combined with the attached manual 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 movement of the lifting device, 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 being unable to fall smoothly into the positioning portion and affecting assembly; 2. 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 guiding and blocking the retaining spring, resulting in the retaining spring being unable to fall smoothly into the positioning portion.

When the equipment is running, the vibration frequency to which the two are subjected remains the same, thereby reducing the influence of the vibration generated during the operation of the equipment on the retaining spring feeding accuracy, and improving the retaining spring feeding accuracy and smoothness.

[0006] A further arrangement of the utility model is that a material guide block is provided on one side of the driving chassis parallel to the moving direction of the material tray, the material guide block and the material barrel connecting block are respectively arranged on both sides of the driving chassis, the material guide block is L-shaped, comprising a connecting portion connected to the driving chassis, and a material guide portion matched with a retaining spring storage barrel, an arc-shaped material guide groove is provided on the material guide portion, an end of the material guide groove away from the chassis is provided with a chamfer, the arc-shaped inner wall of the material guide groove is adapted to the outer periphery of the retaining spring, a gap is provided between the arc-shaped inner wall of the material guide groove and the retaining spring storage barrel for placing the retaining spring, and a height difference between the material guide portion and the material tray is less than the thickness of a retaining spring.

[0007] The utility model with the above-mentioned characteristics: the retaining spring at the end of the retaining spring storage barrel is placed in the material guide groove, and the material guide groove has a guiding effect on the retaining spring, so that the outer peripheral walls of several retaining springs located in the material guide groove remain neat, ensuring the smoothness of material dropping; a chamfer is set at the upper end of the material guide groove, so that the retaining spring located above the material guide groove can smoothly enter the material guide groove along the chamfer when falling; the height difference between the material guide part and the material tray is set to be less than the thickness of one retaining spring. When one retaining spring falls into the positioning part, the material guide part can block the remaining retaining springs to prevent the remaining retaining springs from falling in, ensuring smooth operation.

[0008] A further configuration of the utility model is that the positioning portion is a retaining spring groove arranged on the material tray, and at least one magnetic attraction member for adsorbing the retaining spring is arranged at the bottom of the retaining spring groove.

[0009] The utility model with the above characteristics: the magnetic attraction component can absorb the retaining spring into the retaining spring groove, and the provision of the magnetic attraction component can increase the stability of the retaining spring on the material tray.

[0010] A further configuration of the utility model is that a plurality of positioning grooves are provided on the outer peripheral wall of the retaining spring storage barrel, and the positioning grooves extend from top to bottom. When the retaining spring is sleeved on the outer side of the retaining spring storage barrel, the teeth on the retaining spring are embedded in the positioning grooves.

[0011] The utility model with the above-mentioned features: the number of positioning grooves is set according to the number of teeth on the retaining spring, thereby improving the installation matching of the retaining spring on the retaining spring storage barrel.
