Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of spring ring assembly equipment, in particular to a buckling piece feeding mechanism of a spring ring assembly machine. BACKGROUND

[0002] The spring ring is in a whole annular structure, which includes a spring ring body, a buckling piece, a torsion spring, a rivet and the like. The spring ring body is provided with an opening at one end, and the spring ring body and the head of the buckling piece are both provided with a rivet hole. The two are hinged together by the rivet passing through the rivet hole. The tail of the two forms a closable normally closed switch buckle. The closed loop formed between the spring ring body and the buckling piece is an elastic buckle. The torsion spring is installed between the spring ring body and the buckling piece. The circle of the torsion spring is fixed at the hinged place of the spring ring body and the buckling piece by the rivet. Pressing the buckling piece can compress the torsion spring and rotate relative to the spring ring body, thereby forming an opening between the spring ring body and the buckling piece. Then the buckling piece is released. Under the action of the torsion spring, the buckling piece can restore to its original state.

[0003] At present, in the automatic assembly equipment of the spring ring, such as the Chinese invention patent with the application number CN202210827581.0 and the name "spring buckle automatic assembly equipment", and the Chinese invention patent with the application number CN202310292751.4 and the name "spring ring assembly machine", the buckling piece will be pushed to the spring ring body which has been preliminarily assembled with the torsion spring at the opening, and the buckling piece will be installed at the opening of the spring ring body, thereby completing the assembly process of closing the opening. However, in the above-mentioned equipment, the structure related to this assembly process is relatively complex, and the equipment manufacturing cost is high.

[0004] In addition, in the key action of assembling the buckling piece to the tooling die (the spring ring body assembled with the torsion spring is located on the tooling die at this time), the Chinese invention patent with the application number CN202310292751.4 adopts the following way (also the way adopted by all similar equipment on the market): "Under the driving of the door seal assembly horizontal movement cylinder in the door seal assembly feeding assembly, the door seal feeding shovel lifts the door seal shovel in the door seal feeding platform, and the door seal feeding shovel is pressed by the door seal feeding top pressure clamp, and the door seal is pressed in the door seal feeding shovel. The door seal feeding platform is sent to the corresponding position of the tooling die, so that the door seal is in place, and then the door seal in place lifting block rises to limit the door seal in the tooling die."

[0005] As can be seen from the above, the equipment on the market usually chooses to directly push the buckling piece to the opening of the spring ring body in this key action. In this process, the buckling piece will often mistakenly touch the torsion spring, thereby causing the torsion spring to be misaligned, and the assembly precision cannot be guaranteed. Therefore, the above-mentioned technical problems need to be improved. SUMMARY

[0069] The distribution device 30 is installed on one side of the feeding guide rail 20, which is used for spacing and blocking the buckle a in the sliding way 21;

[0070] Second mounting frame 40;

[0071] The receiving transfer device 60 is installed on the second mounting frame 40, and the receiving transfer device 60 is provided with a push channel 63 and a receiving channel 64 which are communicated with each other, wherein one side of the receiving channel 64 is communicated with the discharge port;

[0072] The carry drive pressing device 50 is installed on the second mounting frame 40, and comprises a driving source, a connecting seat 52 connected with the driving source, and a push rod 53 fixed on the connecting seat 52, and the push rod 53 is matched with the push channel 63;

[0073] The compression positioning device 80 is installed above the tooling mold base 90, and is connected with the main driving source of the spring ring assembly machine, and the compression positioning device 80 comprises:

[0074] The driving pressure part 81 is connected with the main driving source and moves up and down;

[0075] The compression holding part 82 is installed below the driving pressure part 81 and directly above the spring ring body b;

[0076] The top pressing assembly 83 comprises a sleeve rod 831 and positioning blocks 832 and limiting blocks 833 installed at both ends of the sleeve rod 831, wherein the sleeve rod 831 slides through the pressing portion 82, the positioning blocks 832 and the limiting blocks 833 are respectively located at both sides of the pressing portion 82, and the positioning blocks 832 are located close to one side of the material receiving channel 64;

[0077] The compression spring 84 is installed between the pressing portion 82 and the positioning blocks 832;

[0078] The push rod 53 is used for pushing the fastener a in the material receiving channel 64 to the tooling die seat 90 at intervals. As a preferred embodiment of the present embodiment, the lower end of the positioning block 832 is lower than the lower end of the pressing portion 82. Please refer to Figure 6 and Figure 11 It can be seen that, in the present embodiment, the pressing portion 82 and the positioning blocks 832 are respectively provided with mounting holes 821 for mounting the end portions of the compression spring 84, and the compression spring 84 is arranged horizontally.

[0079] Then, the top pressing assembly 83 has a positioning state, a semi-positioning state and a separation state, wherein,

[0080] In the positioning state, the compression spring 84 is in a free state, and the positioning blocks 832 are pressed down to the top of the torsion spring;

[0081] In the semi-positioning state, the compression spring 84 is in a compressed state, and the two sides of the positioning blocks 832 respectively abut to the push rod 53 and the pressing portion 82;

[0082] In the separation state, the positioning blocks 832 move up and away from the torsion spring, and the compression spring 84 is in a free state.

[0083] Please refer to Figure 4 and Figure 9 It can be seen that, before the fastener a is pushed to the opening of the spring ring by the push rod 53, the top pressing assembly 83 is in the separation state. In fact, at this time, the tooling die seat 90 may not have been rotated to the directly below the pressing and positioning device 80 by the dividing disc of the spring ring assembling machine, for the convenience of description, it is assumed that the tooling die seat 90 has been rotated to the directly below the pressing and positioning device 80.

[0084] Please refer to Figure 6 and Figure 11 It can be seen that, when the fastener a is about to be pushed to the opening of the spring ring by the push rod 53 (at this time, the fastener a has not entered the opening of the spring ring), the main driving source of the spring ring assembling machine drives the pressing portion 82 to move down to the lowest position and press the spring ring (position the spring ring on the tooling die seat 90), at this time, the top pressing assembly 83 is in the positioning state, the positioning blocks 832 are above the torsion spring, and the torsion spring is pressed and positioned.

[0085] Please refer to Figure 5 and Figure 10 It can be seen that, in the process of pushing the fastener a into the opening of the spring ring by the push rod 53, the fastener a will abut to the positioning block 832, and continue to push the positioning block 832 forward and abut to the pressing part 82, at this time the compression spring 84 is in a compressed state. Note that, in the process of the fastener a entering the opening of the spring ring, the positioning block 832 and the fastener a are always in abutment and jointly press the torsion spring, so that the torsion spring will not be loosened or displaced due to the pushing of the fastener a. In this way, it can be ensured that after the fastener a is assembled into the opening of the spring ring, the torsion spring will be accurately positioned at the rivet hole position and will not be misaligned.

[0086] When the fastener a is completely assembled into the opening of the spring ring, the main drive source of the spring ring assembly machine drives the driving pressure part 81 to move upward, at this time the positioning block 832 is out of the abutment state with the fastener a, and the top pressure assembly 83 is switched to a separated state, at the same time, the drive source of the carry-in driving device 50 drives the push rod 53 to reset, and enters the next assembly action of the fastener a.

[0087] As another preferred embodiment of the present embodiment, please refer to Figure 3 and Figure 8 It can be seen that the material receiving and transferring device 60 includes a material receiving seat 61, above which a material guide plate 62 is arranged for cooperating to form a pushing channel 63 and a material receiving channel 64, and the material guide plate 62 is provided with a concave accommodation guide opening 621 on the side close to the material receiving channel 64. Here, since the fastener a is arc-shaped, the concave accommodation guide opening 621 is mainly arranged for accommodating the fastener a to be placed in the material receiving channel 64.

[0088] Please refer to Figure 3 , Figure 7 and Figure 12 It can be seen that the material receiving seat 61 is provided with a material pressing device 70, and the material pressing device 70 includes:

[0089] a third cylinder 71 fixedly installed below the material receiving seat 61,

[0090] a vertical sliding rod 72 linked to the cylinder shaft of the third cylinder 71 and vertically sliding through the material receiving seat 61;

[0091] a material pressing block 73 installed above the vertical sliding rod 72 and above the material receiving seat 61, and the material pressing block 73 is provided with a downward extending pressing convex position 731 above the material receiving channel 64.

[0092] In this embodiment, the third cylinder 71 drives the pressing block 73 to press down through the vertical sliding rod 72 during the process that the end of the push rod 53 enters the receiving channel 64 and transports the snap element a to the side close to the tooling die 90. The pressing position 731 on the pressing block 73 will enter the receiving channel 64 and press the snap element a to prevent the snap element a from rotating during the process of being pushed by the push rod 53. Here, if the snap element a rotates, it will affect the subsequent assembly of the opening of the snap element a and the spring ring body b.

[0093] As another preferred embodiment of the present embodiment, the second mounting frame 40 comprises:

[0094] The main support 41 is installed above the frame of the spring assembly machine;

[0095] The horizontal connecting plate 42 is fixed on the main support 41 and located below the receiving transfer device 60;

[0096] The vertical connecting plate 43 is fixed on the horizontal connecting plate 42, and the end of the feeding guide rail 20 and the receiving seat 61 are both fixedly installed on the vertical connecting plate 43.

[0097] In this embodiment, the driving source is the second cylinder 51, which is fixedly installed on one side of the main support 41. More specifically, please refer to Figure 1 and Figure 13 The distributing device 30 comprises:

[0098] The connecting seat 33 is fixedly installed on the feeding guide rail 20, and a sliding groove is provided through the connecting seat 33;

[0099] The first cylinder 31 is fixed on the connecting seat 33;

[0100] The horizontal moving block 32 is connected to the cylinder shaft of the first cylinder 31;

[0101] The guide block 34 is slidably connected in the sliding groove, and one end of the guide block 34 is connected to the horizontal moving block 32. One side of the guide block 34 is provided with a front protruding position 342, a recessed position 341 and a rear protruding position 343 in sequence along the conveying direction of the snap element a;

[0102] The fixed sleeve 310 is installed above the connecting seat 33, and the front sliding arm 35 and the rear sliding arm 36 are slidably provided in sequence on the fixed sleeve 310 along the conveying direction of the snap element a. The front sliding arm 35 and the rear sliding arm 36 are spaced apart from each other, and one end of each of the front sliding arm 35 and the rear sliding arm 36 extends to the guide block 34;

[0103] The front distributing piece 37 is installed above the front sliding arm 35;

[0104] The rear distributing piece 38 is installed above the rear sliding arm 36;

[0105] The limiting baffle 39 is installed on the side of the connecting seat 33 away from the horizontal moving block 32;

[0106] The spring is arranged between the front sliding arm 35 and the limiting baffle 39 and between the rear sliding arm 36 and the limiting baffle 39; and the front distribution sheet 37 and the rear distribution sheet 38 are inserted into the sliding channel 21 in an interval.

[0107] The working principle of the distribution device 30 is as follows: the first cylinder 31 drives the guide block 34 to slide in the sliding groove of the connecting seat 33 through the transverse block 32, and the front convex position 342, the concave position 341 and the rear convex position 343 are sequentially arranged on one side of the guide block 34 along the conveying direction of the buckling piece a. The conveying direction of the buckling piece a is a forward direction, and the direction opposite to the forward direction is a reverse direction. When the guide block 34 moves in the reverse direction, the end of the front sliding arm 35 transitions from the front convex position 342 to the concave position 341, and the end of the rear sliding arm 36 transitions from the concave position 341 to the rear convex position 343. Since the front distribution sheet 37 is installed on the front sliding arm 35, and the rear distribution sheet 38 is installed on the rear sliding arm 36, at this time, the spring between the front sliding arm 35 and the limiting baffle 39 is switched to a natural state, the spring between the rear sliding arm 36 and the limiting baffle 39 is switched to a compressed state, and then the front distribution sheet 37 is inserted into the sliding channel 21, and the rear distribution sheet 38 is away from the sliding channel 21.

[0108] When the guide block 34 moves in the forward direction, the end of the front sliding arm 35 transitions from the concave position 341 to the front convex position 342, and the end of the rear sliding arm 36 transitions from the rear convex position 343 to the concave position 341. Similarly, at this time, the spring between the front sliding arm 35 and the limiting baffle 39 is switched to a compressed state, the spring between the rear sliding arm 36 and the limiting baffle 39 is switched to a natural state, and then the rear distribution sheet 38 is inserted into the sliding channel 21, and the front distribution sheet 37 is away from the sliding channel 21.

[0109] In summary, the first cylinder 31 drives the guide block 34 to slide back and forth in the sliding groove of the connecting seat 33 through the transverse block 32, so as to drive the front distribution sheet 37 and the rear distribution sheet 38 to be inserted into the sliding channel 21 in an interval, and complete the distribution action of the buckling piece a.
