Technical Field
[0001] The utility model belongs to the technical field of core component assembly, and in particular relates to an assembly device for a clamping spring. Background Art
[0002] The core assembly is a commonly used accessory in the solenoid valve. In order to facilitate installation in the solenoid valve, a retaining spring is often installed in the groove of the core body. The general existing assembly process is to manually place the core body in the positioning mold, and then place the retaining spring on the pneumatic pressure rod, and close the pneumatic pressure rod to the core body, so as to install the retaining spring in the groove of the core body. Since the core body and the retaining spring need to be placed manually each time, the assembly efficiency of the retaining spring and the core body is low, and the degree of automation is low. At the same time, the core body is often not well positioned during the assembly process. The retaining spring is installed at the end of the core body. The core body is prone to warping during the assembly process, which makes it impossible for the retaining spring to be accurately aligned with the groove of the core body; the retaining spring is easy to twist during the insertion process, which makes it impossible for the retaining spring to be firmly stuck on the core body. Therefore, it is necessary to design an assembly device for retaining springs to overcome the above difficulties. Summary of the invention
[0003] In view of the problems existing in the prior art, the utility model designs an assembly device for retaining springs. The utility model fixes the core body by a positioning component and a limit cylinder, and continuously presses the retaining springs by a crimping cylinder and a retaining spring pressure plate. The retaining spring crimping efficiency is high and the operation can be carried out continuously. The cooperation is reliable and the degree of automation is high.
[0004] The invention objective of the utility model is achieved through the following technical solutions: an assembly device for retaining springs, comprising a fuselage platform, a circulating synchronous belt assembly for conveying an iron core body is provided on the fuselage platform, a compression retaining spring assembly is provided above the circulating synchronous belt assembly; the circulating synchronous belt assembly comprises a mounting bracket, a conveyor belt and a circulating carrier, the mounting bracket is provided with a positioning assembly for fixing the iron core body; the compression retaining spring assembly comprises a crimping cylinder, a limiting cylinder, a retaining spring pressure plate, a feeding track and a vibrator, the crimping cylinder controls the retaining spring pressure plate to approach the groove on the iron core body when working; the retaining spring pressure plate is provided with a plurality of magnets for absorbing retaining springs, and the feeding track is installed on the vibrator; a limiting block is provided below the feeding track, and the limiting block and the retaining spring pressure plate are arranged parallel to each other; a feeding assembly is provided at the end of the circulating synchronous belt assembly.
[0005] Preferably, the circulation synchronous belt assembly also includes a driving motor, a transmission pin and a pulley; the mounting bracket is arranged on the upper end surface of the fuselage platform, and the transmission pin is installed on the mounting bracket through a bearing; the outer sleeve of the transmission pin is installed with a pulley that rotates synchronously with it, and the outer sleeve of the pulley is installed with a conveyor belt, and the conveyor belt is provided with a number of circulation carriers for transporting the iron core body; the driving motor is installed on the mounting bracket, and a coupling is provided between the driving motor and the transmission pin to connect the two; a positioning assembly is provided on the side of the mounting bracket.
[0006] When the driving motor is working, the transmission pin shaft is driven to rotate, and when the transmission pin shaft rotates, the belt pulley is driven to rotate, and the belt pulley drives the conveyor belt to rotate, thereby the flow conveyor moves relative to the mounting bracket. A positioning component is provided on the mounting bracket to facilitate fixing the iron core body in the flow conveyor.
[0007] Preferably, the positioning assembly includes a mounting plate, a positioning cylinder and a first positioning rod; the mounting plate is fixedly mounted on the side of the mounting bracket, a positioning cylinder is provided on the mounting plate, and a first positioning rod is provided on the piston shaft of the positioning cylinder; the first positioning rod is coaxially arranged with the core body on the flow carrier.
[0008] When the positioning cylinder is working, the first positioning rod moves toward the end of the core body, thereby axially limiting the core body to prevent the core body from moving relative to the flow carrier.
[0009] Preferably, the compression spring assembly also includes a first bracket, a second bracket, a guide plate and a slider; the first bracket is provided with a guide plate, and the top of the first bracket is provided with a crimping cylinder; the guide plate is provided with a guide rail, and the guide rail is provided with a slider; the piston shaft of the crimping cylinder is connected to the slider, and the lower end surface of the slider is provided with a compression spring plate that moves synchronously with it; a limiting cylinder is provided at the bottom of the guide plate, and the piston shaft of the limiting cylinder is arranged opposite to the core body on the flow carrier; a vibrator is provided on the second bracket, and a feeding rail is provided on the vibrator, and the feeding rail and the compression spring plate are arranged perpendicular to each other.
[0010] When the vibrator is working, it will transport the circlip to the circlip pressure plate. When the circlip is close to the end face of the circlip pressure plate, it will be adsorbed onto the circlip pressure plate. Before the crimping cylinder works, the limit cylinder works to make the piston shaft of the limit cylinder abut against the core body, thereby pressing the core body to prevent the core body from tilting when the circlip is pressed. Then the crimping cylinder works to control the slider to move along the guide track, so that the slider will control the circlip pressure plate to move down, thereby clamping the circlip in the groove of the core body. When the circlip pressure plate moves down, the magnet on the circlip pressure plate is misaligned with the feeding track, and the new circlip will be separated by the end face of the circlip pressure plate, and the new circlip cannot be adsorbed onto the circlip pressure plate. When the crimping cylinder controls the circlip pressure plate to reset, the magnet and the circlip are automatically aligned, so that the new circlip will be adsorbed onto the circlip pressure plate, and then a new clamping can be performed.

[0012] By setting the guide plate, the vertical movement of the slider is more stable, the placement groove is aligned with the groove on the core body more accurately, and the retaining spring can be reliably clamped on the core body. By setting the placement groove, the retaining spring can be adsorbed into the placement groove; when the retaining spring is in the placement groove, the end face of the retaining spring is flush with the end face of the retaining spring pressure plate, so that the retaining spring pressure plate will not interfere with the limit block during the downward movement.

[0014] By setting the limit stopper and the guide plate to cooperate with each other, the clamp spring pressure block is clamped between the limit stopper and the side wall of the guide plate during the downward movement, so that the downward movement of the clamp spring pressure block is more stable. By setting the bending limit plate to limit the clamp spring, the clamp spring can reliably move along the axial direction of the feeding track during the operation of the vibrator, and the clamp spring is prevented from being separated from the feeding track.
[0015] Preferably, the unloading assembly includes a third bracket, a first slide cylinder, a second slide cylinder and a clamping cylinder; the first slide cylinder is vertically arranged, and the second slide cylinder is horizontally arranged; the first slide cylinder includes a first cylinder body and a vertical slide, and the second slide cylinder is arranged on the vertical slide; the second slide cylinder includes a second cylinder body and a horizontal slide, and a clamping cylinder is arranged on the horizontal slide; the clamping arm on the clamping cylinder is arranged toward the circulation conveyor.

When the second slide is working, the second cylinder body controls the horizontal slide to move left and right. In this way, the first slide cylinder and the second slide cylinder cooperate with each other to control the clamping cylinder to move arbitrarily in the horizontal and vertical directions, so as to clamp the iron core body in the circulation transport and place it in the unloading frame.
[0017] Preferably, when the first cylinder body is working, the vertical slide moves up and down relative to it, and when the second cylinder body is working, the horizontal slide moves left and right relative to it; the clamping cylinder is arranged near the middle of the flow conveyor.
[0018] Compared with the prior art, the utility model has the following beneficial effects: the utility model sets a circulating synchronous belt assembly on the fuselage platform, which is convenient for continuously transporting the core body through the circulating carrier; a positioning assembly is set on the mounting bracket, and the core body is positioned by the positioning assembly, so that the position of the subsequent compression spring is more accurate.

[0031] The specific working process of this embodiment is as follows: when the circulation synchronous belt assembly 2 is working, the core body is transported to the bottom of the compression spring assembly 3 through the circulation carrier 23.
