Description

Technical Field

[0001] This utility model relates to the field of dynamic spring assembly technology, specifically to a novel dynamic spring insertion mechanism. Background Technology

[0002] In the manufacturing of electrical switching equipment such as relays and contactors, the moving spring assembly is a key functional component, and its assembly quality and efficiency directly affect the performance and production efficiency of the entire electrical product. One existing moving spring assembly consists of a base plate, a moving contact, and a V-shaped spring. The base plate is located inside the V-shaped spring, and the two are riveted together by the moving contact, forming a combined structure with stable electrical connection and mechanical action. Furthermore, the V-shaped spring has through holes, a design that provides a crucial structural basis for the assembly of the moving spring assembly with other components.

[0003] In the actual assembly process of the moving spring assembly, the moving spring assembly needs to be precisely placed on top of other pre-prepared workpieces, aligning the protrusions on the workpieces with the through holes of the moving spring assembly. Then, by applying a certain downward pressure, the protrusions on the workpieces are smoothly forced through the through holes of the moving spring assembly, thus firmly pressing the moving spring assembly and the workpiece together as a single unit. This assembly process has strict requirements on the relative positional accuracy between the moving spring assembly and the workpiece, as well as the pressure application position; any slight deviation may lead to unstable electrical connections or malfunctioning mechanical movements.

[0004] However, the manual pressing method commonly used in the industry has many obvious drawbacks. Because the perforation and protrusion use a transition fit, considerable force is required during assembly to ensure the workpiece protrusion smoothly penetrates the perforation of the moving spring assembly and presses the assembly into place. This significantly increases the labor intensity of the operators. Furthermore, due to the inherent randomness and uncertainty of manual operation, incomplete pressing is prone to occur, such as the workpiece protrusion failing to fully penetrate the perforation, making it difficult to guarantee the assembly accuracy and quality stability of the moving spring assembly.

[0005] Given the numerous drawbacks of the aforementioned manual pressing method, it is particularly necessary to develop a new type of moving spring insertion mechanism. Utility Model Content

[0007] This utility model provides a novel moving spring mounting mechanism, which can at least solve the technical problem of how to automatically assemble the moving spring into the workpiece.

[0008] (II) Technical Solution

[0009] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel moving spring loading mechanism, comprising:

[0010] The frame has an installation station.

[0011] The workpiece fixture is located at the installation station and is used to accommodate and limit the workpiece and the movable spring assembly inserted thereon.

[0012] A positioning component, mounted on the frame, is used to fix the workpiece in the mounting position;

[0013] The pressure block and the pressure block drive assembly are mounted on the frame and connected to the pressure block drive. The pressure block drive assembly is used to drive the pressure block to move relative to the mounting station, pressing or releasing the moving spring assembly and the workpiece on the mounting station.

[0014] In a further configuration, the aforementioned positioning component includes a clamping drive and two clamping arms. The two clamping arms are respectively located on both sides of the installation station. The clamping drive is located on the frame and is connected to the two clamping arms in a transmission manner. The clamping drive is used to drive the two clamping arms to move towards or away from each other in order to clamp or release the workpiece on the installation station.

[0015] Furthermore, the aforementioned novel moving spring loading mechanism also includes a conveyor line, which is mounted on the frame and used to continuously transport workpiece fixtures one by one.

[0016] The positioning assembly includes a first lifting drive, a clamping drive, and two clamping arms. The first lifting drive is mounted on the frame, and the two clamping arms are respectively mounted on both sides of the installation station. The clamping drive is mounted on the output end of the first lifting drive and is connected to the two clamping arms in a transmission manner.

[0017] The first lifting drive is used to drive the clamping drive and the two clamping arms to move up and down relative to each other at the mounting station. The clamping drive is used to drive the two clamping arms to move towards or away from each other.

[0018] In a further configuration, the aforementioned positioning component also includes a stop block, which is located on the side of the workpiece facing away from the conveying direction at the installation station. The first lifting drive component is also connected to the stop block in a transmission manner, and the first lifting drive component is also used to drive the stop block to move up and down relative to the installation station.

[0019] Further, the aforementioned stop includes a side stop and an upper stop that are vertically connected. The upper stop is located above the moving spring assembly at the installation station and is used to restrict the moving spring assembly from moving upward and disengaging from the workpiece. The side stop is located on the side of the workpiece at the installation station that faces away from the conveying direction and is used to restrict the workpiece from moving out of or deviating from the installation station.

[0020] In a further configuration, the aforementioned positioning component also includes a first translational drive component, which is located on the output end of the first lifting drive component and is connected to the stop block via a transmission connection. The first translational drive component is used to drive the stop block to move along the conveying direction of the conveyor line.

[0021] In a further configuration, the aforementioned pressure block driving assembly includes a second translational driving component and a second lifting driving component connected to each other. The second translational driving component is used to drive the pressure block to move relative to the installation station along the conveying direction of the conveyor line, so that the pressure block and the protrusion of the workpiece are positioned relative to each other. The second lifting driving component is used to drive the pressure block to move relative to the installation station in the vertical direction.

[0022] Furthermore, the aforementioned pressure block is provided with clearance recesses. The number of clearance recesses is the same as the number of protrusions on the workpiece, and their positions are one-to-one. The clearance recesses are used for the corresponding protrusions to be inserted.

[0023] (III) Beneficial Effects

[0024] Compared with the prior art, the novel moving spring loading mechanism provided by this utility model has the following advantages:

[0025] Beneficial effects:

[0026] When using the novel moving spring loading mechanism provided by this utility model, firstly, the moving spring assembly is placed on the workpiece of the workpiece fixture manually or through the moving spring feeding mechanism, so that the protrusion of the workpiece is aligned and inserted with the through hole of the moving spring assembly; then, the positioning component fixes the workpiece at the installation station to prevent the workpiece from moving during subsequent assembly and affecting the assembly; next, the pressure block driving component drives the pressure block to move toward the protrusion of the workpiece at the installation station, pressing down on the workpiece and the moving spring assembly at the installation station, so that the protrusion of the workpiece passes through the through hole of the moving spring assembly, thereby pressing the moving spring assembly and the workpiece together; finally, the pressure block driving component drives the pressure block to release the moving spring assembly and the workpiece at the installation station, and at the same time the positioning component releases the workpiece at the installation station, so that the assembled moving spring assembly and the workpiece can be moved out of the installation station.

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] This utility model provides a novel moving spring loading mechanism to solve the problem of how to automatically load the moving spring assembly 7 onto the workpiece 6.

[0039] See Figure 1 As shown, Figure 1 The figure shows a perspective view of the novel moving spring loading mechanism in the embodiment. The novel moving spring loading mechanism includes a frame 1, a workpiece fixture 2, a positioning component 3, a pressure block 4, and a pressure block driving component 5.

[0040] The frame 1 is equipped with an installation station 11.

[0041] The workpiece fixture 2 is located on the installation station 11. The workpiece fixture 2 is used to accommodate and limit the workpiece 6 and the movable spring assembly 7 inserted thereon.

[0042] The positioning component 3 is mounted on the frame 1 and is used to fix the workpiece 6 on the mounting station 11.

[0043] The pressure block drive assembly 5 is mounted on the frame 1 and is connected to the pressure block 4 in a transmission manner. The pressure block drive assembly 5 is used to drive the pressure block 4 to move relative to the mounting station 11, thereby pressing down or releasing the moving spring assembly 7 and the workpiece 6 on the mounting station 11.

[0044] When using the novel moving spring loading mechanism described above, firstly, the moving spring assembly 7 is placed on the workpiece 6 of the workpiece fixture 2 manually or through the moving spring feeding mechanism, so that the protrusion 61 of the workpiece 6 is aligned and inserted with the through hole 71 of the moving spring assembly 7; then, the positioning component 3 fixes the workpiece 6 on the mounting station 11 to prevent the workpiece 6 from moving during subsequent assembly and affecting the assembly; next, the pressure block driving component 5 drives the pressure block 4 to move toward the mounting station 11, pressing down on the workpiece 6 and the moving spring assembly 7 on the mounting station 11, so that the protrusion 61 of the workpiece 6 passes through the through hole 71 of the moving spring assembly 7, thereby pressing the moving spring assembly 7 and the workpiece 6 together; finally, the pressure block driving component 5 drives the pressure block 4 to release the moving spring assembly 7 and the workpiece 6 on the mounting station 11, and at the same time, the positioning component 3 releases the workpiece 6 on the mounting station 11 so that the assembled moving spring assembly 7 and the workpiece 6 can be moved out of the mounting station 11. It can be seen that the new type of moving spring loading mechanism, through the cooperation of workpiece fixture 2, positioning component 3, pressure block 4 and pressure block driving component 5, can position and press the moving spring assembly 7 and workpiece 6 on the installation station 11, realize the automatic and precise loading of the moving spring assembly 7 into the workpiece 6, replace manual assembly, thereby greatly improving assembly efficiency and quality stability, solving the efficiency and quality problems caused by manual assembly, and also reducing labor intensity.

[0045] The aforementioned workpiece fixture 2 can be directly welded or screwed onto the installation station 11. Before assembly, the workpiece 6 can be placed on the workpiece fixture 2 manually or automatically by a feeding mechanism. Then, the moving spring assembly 7 is placed and inserted into the workpiece 6 on the workpiece fixture 2. After installation, the assembled moving spring assembly 7 and workpiece 6 are removed from the workpiece fixture 2 manually or by a unloading mechanism. Then, the next workpiece 6 to be assembled and the moving spring assembly 7 are placed into the workpiece fixture 2 in sequence. Alternatively, the aforementioned workpiece fixture 2 can also be continuously fed into and out of the installation station 11 one by one via a conveyor line.

[0046] In a first embodiment of the positioning component 3, the positioning component 3 includes a clamping drive 31 and two clamping arms 32. The two clamping arms 32 are located on both sides of the mounting station 11. The clamping drive 31 is mounted on the frame 1 by means of screwing or welding, and is connected to the two clamping arms 32 in a transmission manner. The clamping drive 31 is used to drive the two clamping arms 32 to move towards or away from each other to clamp or release the workpiece 6 on the mounting station 11. In this way, the positioning component 3, through the cooperation of the clamping drive 31 and the two clamping arms 32, can clamp and fix the workpiece 6 on the mounting station 11, effectively preventing the workpiece 6 from moving, leaving or deviating from the mounting station 11 during the assembly process. It can be seen that this embodiment is more suitable for fixed workpiece fixture 2, effectively avoiding interference between the positioning component 3 and the workpiece fixture 2, its moving spring assembly 7, and the workpiece 6.

[0047] The aforementioned clamping drive unit 31 can be a clamping mechanism such as a clamping cylinder or a clamp.

[0048] See Figure 1 and Figure 2 As shown, Figure 2 for Figure 1 The enlarged schematic diagram at point A shows that in the second embodiment of the positioning component 3, the positioning component 3 includes a first lifting drive 33, a clamping drive 31, and two clamping arms 32. The novel moving spring loading mechanism also includes a conveyor line (not shown in the figure), which is mounted on the frame and used to continuously transport the workpiece fixture 2 one by one. The first lifting drive 33 is mounted on the frame 1 by means of screwing or welding. The two clamping arms 32 are located on both sides of the mounting station 11. The clamping drive 31 is mounted on the output end of the first lifting drive 33 by means of screwing or welding and is connected to the two clamping arms 32 in a transmission manner. The first lifting drive 33 is used to drive the clamping drive 31 and the two clamping arms 32 to move up and down relative to the mounting station 11; the clamping drive 31 is used to drive the two clamping arms 32 to move towards or away from each other. Thus, when the conveyor line transports the workpiece fixture 2 to the installation station 11, the first lifting drive 33 drives the two clamping arms 32 to descend to both sides of the installation station 11. Then, the clamping drive 31 drives the two clamping arms 32 to move towards each other, thereby achieving the clamping and positioning function of the workpiece 6 on the installation station 11. Until the assembly is completed, the clamping drive 31 drives the two clamping arms 32 to move away from each other, releasing the workpiece 6 on the installation station 11. Then, the first lifting drive 33 drives the two clamping arms 32 to rise away from the installation station 11. At this time, the conveyor line can send the workpiece fixture 2 out of the installation station 11. It can be seen that this implementation method is suitable for mobile workpiece fixtures 2. After each assembly, the first lifting drive 33 drives the two clamping arms 32 to rise away from the installation station 11, which can effectively avoid interference between the positioning component 3 and the workpiece fixture 2, its moving spring assembly 7, and the workpiece 6.

[0049] The aforementioned first lifting drive component 33 can be a linear drive mechanism such as a telescopic cylinder or a linear module. The aforementioned conveyor line can be formed using a conveyor belt mechanism, a roller mechanism, or a shift fork mechanism.

[0050] See Figure 1 and Figure 2 As shown, based on the above embodiment, the positioning component 3 further includes a stop 34. The stop 34 is located on the side of the workpiece 6 facing away from the conveying direction at the installation station 11. The first lifting drive 33 is also connected to the stop 34 in a transmission manner. The first lifting drive 33 is also used to drive the stop 34 to move up and down relative to the installation station 11. Thus, when the first lifting drive 33 drives the two clamping arms 32 to descend to both sides of the installation station 11, the stop 34 descends to the side of the workpiece 6 facing away from the conveying direction, which can effectively prevent the workpiece 6 from moving out of or deviating from the installation station 11 with the conveyor line, so that the clamping drive 31 and the two clamping arms 32 cooperate to accurately clamp and fix the workpiece 6 at the installation station 11, thereby ensuring that the moving spring assembly 7 is accurately installed on the workpiece 6.

[0051] See Figure 2 As shown, in one embodiment of the stop block 34, the stop block 34 includes a side stop surface 341 and an upper stop surface 342 connected vertically. The upper stop surface 342 is located above the moving spring assembly 7 at the mounting station 11, and is used to restrict the upward movement of the moving spring assembly 7. The side stop surface 341 is located on the side of the workpiece 6 at the mounting station 11 facing away from the conveying direction, and is used to restrict the workpiece 6 from moving out of or deviating from the mounting station 11. It can be seen that the stop block 34 can not only prevent the workpiece 6 from moving out of or deviating from the mounting station 11 with the conveyor line, but also prevent the moving spring assembly 7 from moving upward and detaching from the workpiece 6, so that the moving spring assembly 7 can be pressed onto the workpiece 6 subsequently.

[0052] See Figure 1 As shown, based on the embodiment of the first lifting drive 33 described above, the positioning assembly 3 further includes a first translation drive 35. The first translation drive 35 is mounted on the output end of the first lifting drive 33 by means of screwing or welding, and is connected to the stop block 34 in a transmission manner. The first translation drive 35 is used to drive the stop block 34 to move along the conveying direction of the conveyor line. Thus, the positioning assembly 3 can adjust the horizontal position of the stop block 34 through the first translation drive 35 to ensure that the stop block 34 accurately blocks the workpiece 6 at the installation position 11, thereby improving the pressing quality of the subsequent moving spring assembly 7 and the workpiece 6.

[0053] The first translation drive 35 mentioned above can be a linear drive mechanism such as a telescopic cylinder or a telescopic pole, and its output end is connected to the stop block 34 by means of screwing or welding.

[0054] See Figure 1 As shown, in one embodiment of the pressure block driving assembly 5, the pressure block driving assembly 5 includes a second translational driving member 51 and a second lifting driving member 52 connected to each other. The second translational driving member 51 is used to drive the pressure block 4 to move relative to the mounting station 11 along the conveying direction of the conveyor line, so that the pressure block 4 and the protrusion 61 of the workpiece 6 are positioned opposite each other. The second lifting driving member 52 is used to drive the pressure block 4 to move relative to the mounting station 11 in the vertical direction. It can be seen that the pressure block driving assembly 5 can accurately control the position of the pressure block 4 through the cooperation of the second translational driving member 51 and the second lifting driving member 52, so that the pressure block 4 is accurately pressed down at the through hole 71 of the moving spring assembly 7, thereby ensuring that the moving spring assembly 7 is pressed into place.

[0055] The aforementioned second translation drive 51 can use a linear drive mechanism such as a stepper motor-lead screw and nut linear module or a servo motor-lead screw and nut linear module, which can precisely control the position of the pressure block 4 in the conveying direction. The aforementioned second lifting drive 52 can use a linear drive mechanism such as a telescopic cylinder or a linear module. In this embodiment, the second translation drive 51 is mounted on the frame 1, and the second lifting drive 52 is mounted on the output end of the second translation drive 51, with the output end of the second lifting drive 52 fixedly connected to the pressure block 4.

[0056] See Figure 2 As shown, based on the above embodiment, the pressure block 4 has a clearance recess 41. The number of clearance recesses 41 is the same as the number of protrusions 61 on the workpiece 6, and their positions are one-to-one. The clearance recesses 41 are used for the insertion of the corresponding protrusions 61. Thus, when the pressure block 4 presses down on the through hole 71 of the moving spring assembly 7, the clearance recesses 41 can provide clearance, making it convenient for the protrusions 61 to pass through the through hole 71 and insert into the clearance recesses 41, so that the through hole 71 of the moving spring assembly 7 can completely cover the upper surface of the workpiece 6, ensuring that the moving spring assembly 7 is pressed into place.
